Do you know how many kinds of bumper cars?
Bumper car is a highly participatory equipment for amusement park playground . It is very popular with tourists. Its technology is getting more and more mature, its performance is getting better and better, and its varieties are getting more and more. It mainly includes Skynet bumper cars, bumper cars without Skynet, and common battery bumper cars.
Skynet amusement park Bumper Cars
Skynet bumper car is a kind of amusement rides which run freely in a fixed venue and can collide with each other. This type of bumper car is driven by a DC motor. The two electrodes for power supply are on the floor and on the ceiling (or net) of the venue respectively. The electric motor is powered by the conductive device on the car body and the trailing needle (ie, the ferris bow) to drive the car. body runs. Bumper cars are driven freely by the passengers, who freely choose to crash. The game is safe, reliable and exciting. A race-like competition concept and a self-driving car experience. It has a strong attraction to tourists.

(1) Main structure
1) The body of the bumper car is composed of manipulation control, transmission, body, chassis, rear wheels, buffer tires, seat belts, conductive rods and electrical switches, as shown in Figure 3-414. It consists of a sky net and a ground net to form a power supply system. After the 220V AC power is transformed and rectified by the control cabinet, the positive and negative poles of the 90V or 110V DC power are respectively applied to the sky net and the ground net. The bumper car obtains the DC voltage from the sky net through the conductive rod at the tail, and forms an electrical circuit with the ground net through the load motor and the rear wheel to realize the operation of the load motor. Through the control of the operating mechanism, the bumper car is driven to move forward, backward, and turn left and right. Because there is a pneumatic tire buffer on the side of the car, it can collide arbitrarily. The body and chassis of the Skynet bumper car are shown in Figure 3-415 and Figure 3-416
At present, most conductive devices on the market use Ferris bows, as shown in Figure 3-417. Because the ferris bow is relatively thin and the contact area with the upper pole plate is small, the ferris bow will destroy the galvanized layer of the upper pole plate under the action of the spring. The plate will be slowly oxidized. Therefore, spark discharges are often generated during the operation of the bumper car, which will cause unnecessary trouble. Now many users have changed to copper wheels, and the weight should not be too heavy, as shown in Figure 3-418. When connecting, try to balance both sides of the copper wheel to prevent one side from being heavy. In addition, the upper plate is very flat, the contact area of the copper wheel is large, and it is not easy to jump to generate a gap, and it is not easy to generate electric sparks. Since the upper plate is not easily oxidized, it is difficult to generate sparks on the plate, so as to ensure that tourists will not be injured by sparks during exercise and collision.

2) Steering mechanism. As shown in Figure 3-419, the steering mechanism is meshed by a bevel gear (Figure 3-420). Passengers only need to rotate the steering wheel, and through this transmission mechanism, the steering of the bumper car is realized. The steering mechanism must be flexible, and the clearance of the bevel gear should be checked frequently to prevent the steering wheel from having a large idle stroke. The steering wheel and steering rod are connected by pins, and the pins will loosen due to long-term collision of bumper cars.

3) The structure and installation of Tianwang depot
①The structure of the parking lot.
The Tiandiwang car yard is mainly composed of roof trusses, skynets, railings, lower poles (ground nets), etc. The distance between the sky and the earth network should be at least 2.7m. Skynet is generally connected to the positive pole of the bumper car. It is mainly composed of hanging device and pole plate. The pole plate is a live body, which is insulated and fixed with the roof truss through the hanging device. It is generally made by riveting zinc plate and its fixed frame, as shown in Figure 3-421. The ground grid is generally composed of ground grid plates and anti-collision bars. The ground plate is the negative pole of the bumper car, which is connected to the zero line of the power supply of the control box through a wire. The ground grid plate is also the operating site of the bumper car, and the ground grid steel plate is required to be connected smoothly and welded firmly. The upper plate is suspended from the ceiling through an angle steel frame. If galvanized steel sheet is used, its thickness should not be less than 0.5mm. If steel plates are used, the thickness should not be less than 2mm, but the gap between two adjacent electrode plates should not be greater than 3mm. The lower plate yard is required to be flat and solid, and there should be no unevenness. Buffer barriers should be set up around the parking lot. Blocks are generally made of channel steel. Its crash surface interface should be polished smooth to avoid damage to bumper car buffer tires. The support frame behind the blocker should be set at intervals.
Figure 3-421 Skynet bumper car upper plate connection
②The installation of the parking lot.
First, ensure that the foundation is level and pre-embed and fix the iron plate according to the drawing. Then arrange channels at intervals as shown in Figure 3-422. Use a welding machine to spot-weld the channel steel at the embedded iron plate, and then scribe the horizontal channel steel after it is arranged. Then transversely weld the channel steel, as shown in Figure 3-423 and Figure 3-424. Note that after the channel steel is welded, it is also necessary to check whether the bottom of the channel steel and the embedded iron plate are fully welded. The channel steel and the embedded iron should be well welded to enhance the connection effect. After the channel steel is laid, concrete should be poured and leveled, as shown in Figure 3-425. When the concrete reaches a certain strength, start laying the lower plate.
Figure 3-422 Laying channel steel at Tianwang bumper car site;Figure 3-423 Tianwang bumper car site positioning transverse channel steel
Figure 3-424 Welding of transverse channel steel in Skynet bumper car site;Figure 3-425 Concrete pouring at Skynet bumper car site
The welding of the lower pole steel plate requires that the length of the welding seam is not less than 30mm, the interval between the welding seams is not more than 300mm, and the gap at the unwelded part should not be more than 3mm. The thickness of the lower pole steel plate shall not be less than 4mm, and the area of each piece shall not be less than 2m2. And each lower pole steel plate shall be welded and connected with the embedded channel steel. Each pole plate is relatively long, and the channel steel is embedded in the middle of the lower part. The ground nail should be installed at the center of the transverse channel, and the welding between the ground nail and the pole plate should be firm and smooth. To ensure that the plate does not arch. After the lower pole steel plate is laid, the weld shall be inspected and repaired according to the requirements.
Working principle
The bumper car is driven by a DC motor, and the positive and negative electrodes of the power supply are respectively connected to the ceiling (sky net) and the floor (ground net). The DC motor can be powered by the conductive device on the car body and the trailing needle (that is, the Ferris bow) and drive the car body to run.
Safety devices
The safety devices of bumper cars are mainly seat belts and buffer devices. They are mainly used to prevent passengers from hitting the steering wheel when playing, because when the vehicle collides, the person will collide with the vehicle due to inertia.
No Skynet amusement park Bumper Cars
The skynet-free bumper car is a new type of equipment that is deformed and improved on the basis of the skynet bumper car. It removes the original long ferris bow and conductive skynet (or upper plate), making it more beautiful. The bumper car is driven by a DC motor, and the two power supply electrodes are located on the specially treated floor, and the electric motor drives the car body to run through the conductive device on the car body.
(1) Main structure.
The whole set of bumper car rides without Skynet is mainly composed of several bumper cars, electrode floors and electrical control systems.
1) Body structure.
The bumper car body is composed of a control mechanism, a transmission mechanism, a body, a chassis (Figure 3-426), conductive wheels, buffer tires, seat belts and electrical switches.
2) The structure of the parking lot.
The floor of the amusement park is made up of positive and negative electrode plates laid alternately on a plane. At the same time, an epoxy resin base layer is also provided under the electrode plate. In this way, the insulation problem between the electrode plate and the ground can be effectively solved. Due to the strong adhesive force of epoxy resin, it can achieve a one-time construction of a flat and firm skyless net parking lot floor. The bulky chassis and dense screws in the original structure are removed, saving a lot of material and labor costs. At the same time, epoxy resin floor parking lot can prevent moisture, and can also adapt to relatively humid environment and atmosphere. The noise in the parking lot is low, and there is no floor resonance sound when the vehicle is running. The flatness of the parking lot is relatively high and the flame retardant performance is good.
Figure 3-426 Bumper car chassis without Skynet
(2) Working principle
The bumper car is driven by a DC motor, and the AC power source is controlled and transformed through an electrical console. Then output the DC voltage to the electrode plate of the parking lot. Then, the positive and negative electrodes of the DC power are respectively delivered to the bumper car through the wheels at the bottom of the car. The direct current is sent to the motor through the foot switch to make the direct current motor rotate. The rotation of the DC motor drives the wheels to run through a centrifugal clutch and a deceleration mechanism. Tourists sit in the car and use foot switches to control driving and stopping. Turn the steering wheel to control the driving direction. Since there are air tire shock absorbers around the car body, any collision is possible.
(3) Safety device
The safety devices of bumper cars without skynet include seat belts, buffer devices, etc.
Battery bumper cars amusement park rides
The battery bumper car is a kind of bumper car that has neither skynet nor ground net. Its power comes from the battery, and it only needs a flat ground to operate the game.
(1) Main structure
The battery bumper car is mainly composed of driving mechanism, steering system, battery, buffer tire, car body, cockpit, seat belt and walking wheel, etc., as shown in Figure 3-427. Its drive mechanism and chassis structure are shown in Figure 3-428 and Figure 3-429. The steering system is used for the steering of the bumper car, and its shape and transmission principle are shown in Figure 3-430 and Figure 3-431. The inflatable buffer tires are located on the outside of the car body, which can slow down the impact force in the event of a collision, thereby avoiding injury to tourists. In addition, seat belts are also installed in the car to prevent the driver from being thrown out of the car, as shown in Figure 3-432.

(2) Working principle.
The operation process of the battery bumper car is as follows: after the passengers get on the car and step on the pedal switch, the motor will run with electricity from the battery, and drive the sprocket on the driving wheel through the chain deceleration, so as to realize the movement of the bumper car.
The steering of the bumper car is realized through the steering wheel. When the passenger wants to change the running direction, the steering wheel is rotated, and the steering wheel drives the steering column to drive the gear to rotate through the steering rod connected to the lower end of the steering knuckle, and then drives the gear to the sector gear to drive the center of the sector tooth. The shaft rotates, and the lower end of the central shaft is equipped with a steering wheel, thereby realizing the steering movement.
(3) Safety device
The safety devices of battery bumper cars mainly include seat belts and buffer devices.

What are included in the large-scale bumper car amusement facilities? What are the common movement feature?
Common bumper car includes skynet bumper car and ground-net bumper car. Their common movement feature is that the vehicles run and collide in a fixed parking lot.
What are the structure feature and movement form of the skynet bumper cars ?
Skynet bumper car is a typical product of large-scale bumper car amusement facilities. To operation of the bumper cars with skynet is to obtain DC power from the skynet and the floor through the conductive pole in the fixed parking lot. When the foot switch in the car is turned on, the conductive device makes the DC motor energize to drive the car body to run. The motor stator is fixed on the steering mechanism, and the rotor shell is equipped with rubber wheels as a wheel. After the motor is energized, the rotor rotates, that is, the wheel rotates. Meanwhile, the steering device can be manipulated to make the motor to do 360° arbitrary turning, so by turning the steering wheel, bumper cars can do forward and backward turning and walking left and right.The structure diagram is shown in Figure 1-20
