Description
Technical Field
[0001] The utility model relates to the technical field of model car door bridge structures, in particular to a model car door bridge structure. Background Art
[0002] The car door bridge structure is a transmission device at the bottom of a motor vehicle. It is responsible for connecting the left front wheel and the right front wheel of the vehicle. By modifying the door bridge, the passability of the motor vehicle can be effectively increased, thereby raising the height of the vehicle chassis and making the vehicle perform better when driving on unpaved roads. The door bridge is an important part of the electric vehicle transmission device. Its basic function is to transmit the power generated by the engine to the driving wheels of the car, enabling the motor vehicle to drive at a certain speed. It should be noted that there is generally no direct power connection between the front wheels of the car and the transmission system, so they are called driven wheels.
[0003] The inventor found during daily use of the car door bridge that the connection between the adjusting rod for adjusting the rotation of the wheel and the door bridge bracket of the car door bridge is exposed for a long time, which leads to a dry phenomenon when the connection rotates. When adjusting the wheel angle, it will cause wear at the connection between the adjusting rod and the door bridge bracket, thereby causing an impact. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a model car door bridge structure is proposed.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A model car door bridge structure includes a driving member. One end of the driving member is provided with a transmission assembly. One end of the transmission assembly is fixedly connected to a rotating shaft. A first bracket is arranged on the surface of the rotating shaft. A second bracket is arranged on the side of the first bracket. A lubricating device is arranged on the upper top of the second bracket. An adjusting rod is rotatably connected inside the second bracket. An angle recognition device is arranged on the upper top of the first bracket. One end of the rotating shaft is fixedly connected to a small gear. The surface of the small gear is meshed and driven by a large gear. A wheel is arranged at one end of the large gear. The lubricating device includes a lubricating tank fixedly connected to the upper top of the second bracket. A discharge pipe is fixedly connected to the bottom of the lubricating tank. The discharge pipe is arranged at the connection between the adjusting rod and the second bracket.
[0006] The effects achieved by the above components are as follows: Under the action of the lubricating device, the connection between the adjusting rod and the second bracket can be lubricated, so that the adjusting rod can be quickly adjusted when adjusting the angle of the wheel. When the door bridge needs to be used, the driving part is connected to the driving machine, so that the two bevel gears inside the transmission component are engaged and driven. Then, one of the bevel gears drives the rotating shaft to rotate, so that the small gear rotates and drives the large gear to rotate, thereby making the wheel rotate and the model car move.
[0007] Preferably, a fixing rod is fixedly connected to the upper top of the adjusting rod, and an extrusion plate is fixedly connected to one end of the fixing rod. The extrusion plate is arranged in the upper half of the lubricating tank.
[0008] The effects achieved by the above components are as follows: Under the action of the fixing rod and the extrusion plate, the upper half of the lubricating tank is extruded, so that the lubricating oil is extruded, and then the connection between the adjusting rod and the second bracket is lubricated.
[0009] Preferably, a rubber block is fixedly connected to the side surface of the extrusion plate, and the rubber block is arranged on the side of the extrusion plate close to the lubricating tank.
[0010] The effects achieved by the above components are as follows: Under the action of the rubber block, the extrusion plate does not make rigid contact with the lubricating tank, thus avoiding the direct contact between the extrusion plate and the lubricating tank.
[0011] Preferably, a sliding plate is slidably connected inside the lubricating tank. A first telescopic rod is fixedly connected to the upper top of the sliding plate, and the other end of the first telescopic rod is fixedly connected to the upper top of the lubricating tank.
[0012] The effects achieved by the above components are as follows: Under the action of the first telescopic rod, the sliding plate can move inside the lubricating tank, thus achieving the effect of pushing out the lubricating oil.
[0013] Preferably, a second telescopic rod is fixedly connected to the side surface of the first telescopic rod. A spring is sleeved on the surface of the second telescopic rod. The other end of the second telescopic rod is fixedly connected to an arc plate, and the arc plate is closely attached to the inner wall of the lubricating tank. Both ends of the spring are fixedly connected to the side surface of the arc plate and the side surface of the first telescopic rod respectively.
[0014] The effects achieved by the above components are as follows: Under the action of the first telescopic rod and the second telescopic rod being squeezed by the squeezing plate, the skateboard moves downward, thereby pushing the lubricating oil out of the lubricating tank, and then lubricating the connection between the adjusting rod and the second bracket. When it is necessary to lubricate the connection between the adjusting rod and the second bracket, when the adjusting rod rotates inside the second bracket, it drives the fixed rod to rotate, thereby causing the squeezing plate to drive the rubber block to squeeze the upper half of the lubricating tank, so that the skateboard inside the lubricating tank is pushed downward by the gas between the lubricating tank and the skateboard, and then the lubricating oil is pushed out of the lubricating tank, and then the lubricating oil lubricates the connection between the adjusting rod and the second bracket through the discharge pipe. Under the action of the second spring, the second telescopic rod can be reset after being squeezed, so that the arc plate supports the upper half of the lubricating tank, and then resets the skateboard, thus achieving the lubricating effect.
[0015] Preferably, the angle recognition device includes an angle recognition sensor fixedly connected to the top of the first bracket, and the probe of the angle recognition sensor is inserted into the connection between the first bracket and the second bracket.
[0016] The effects achieved by the above components are as follows: Under the action of the angle recognition sensor, the angle adjusted between the first bracket and the second bracket can be recognized, thus achieving the effect of facilitating reset.
[0017] Preferably, a pointer is rotatably connected to the side of the first bracket, and an angle recognition disk is fixedly connected to the top of the second bracket.

[0019] Preferably, an inductor is fixedly connected to the top of the angle recognition disk, and a receiver is fixedly connected to the side of the first bracket.
[0020] The effects achieved by the above components are as follows: Under the action of the receiver and the inductor, the angle adjusted between the first bracket and the second bracket can be accurately recognized.

When the car door bridge needs to be used, the driving member 1 is connected to a driving machine, so that two bevel gears inside the transmission assembly 4 are meshed and driven. Then one of the bevel gears drives the rotating shaft 5 to rotate, so that the small gear 6 rotates and drives the large gear 7 to rotate, thereby making the wheel rotate, and further making the model car move.
[0029] Refer to Figure 2, the lubrication device 2 includes a lubricating tank 24 fixedly connected to the top of the second bracket 8. A discharge pipe is fixedly connected to the bottom of the lubricating tank 24. The discharge pipe is arranged at the connection of the adjusting rod 9 and the second bracket 8. Under the action of the lubrication device 2, the connection between the adjusting rod 9 and the second bracket 8 can be lubricated, so that the adjusting rod 9 can be quickly adjusted when adjusting the angle of the wheel. When the door bridge needs to be used, the driving part 1 is connected to the driving machine, so that the two bevel gears inside the transmission component 4 are engaged and driven. Then one of the bevel gears drives the rotating shaft 5 to rotate, so that the small gear 6 rotates and drives the large gear 7 to rotate, thus making the wheel rotate and the model car move. A fixing rod 21 is fixedly connected to the top of the adjusting rod 9. One end of the fixing rod 21 is fixedly connected to a pressing plate 22. The pressing plate 22 is arranged in the upper half of the lubricating tank 24. Under the action of the fixing rod 21 and the pressing plate 22, the upper half of the lubricating tank 24 is squeezed, and then the lubricating oil is extruded, so as to lubricate the connection between the adjusting rod 9 and the second bracket 8. A rubber block 23 is fixedly connected to the side of the pressing plate 22. The rubber block 23 is arranged on the side of the pressing plate 22 close to the lubricating tank 24. Under the action of the rubber block 23, the pressing plate 22 will not make rigid contact with the lubricating tank 24, thus avoiding the direct contact between the pressing plate 22 and the lubricating tank 24.

Under the action of the first telescopic rod 26 and the second telescopic rod 27 being squeezed by the pressing plate 22, the sliding plate 25 moves downward, thus pushing the lubricating oil out of the lubricating tank 24 to lubricate the connection between the adjusting rod 9 and the second bracket 8. When it is necessary to lubricate the connection between the adjusting rod 9 and the second bracket 8, when the adjusting rod 9 rotates inside the second bracket 8, it drives the fixing rod 21 to rotate, so that the pressing plate 22 drives the rubber block 23 to squeeze the upper half of the lubricating tank 24, so that the sliding plate 25 inside the lubricating tank 24 is pushed downward by the gas between the lubricating tank 24 and the sliding plate 25, thus pushing the lubricating oil out of the lubricating tank 24, so that the lubricating oil lubricates the connection between the adjusting rod 9 and the second bracket 8 through the discharge pipe. Under the action of the second spring 29, the second telescopic rod 27 can be reset after being squeezed, so that the arc plate 28 supports the upper half of the lubricating tank 24,Furthermore, the skateboard 25 is reset, thus achieving the lubricating effect.

A pointer 35 is rotatably connected to the side of the first bracket 10, and an angle recognition disk 32 is fixedly connected to the top of the second bracket 8. Under the action of the angle recognition disk 32 and the pointer 35, the angle can be recorded more clearly, and thus the second bracket 8 can be reset very conveniently. An inductor 33 is fixedly connected to the top of the angle recognition disk 32, and a receiver 34 is fixedly connected to the side of the first bracket 10. Under the action of the receiver 34 and the inductor 33, the angle adjusted between the first bracket 10 and the second bracket 8 can be accurately recognized. When it is necessary to recognize the angle between the first bracket 10 and the second bracket 8, the probe of the angle recognition sensor 31 is inserted into the connection between the first bracket 10 and the second bracket 8 for angle recognition. Under the action of the angle recognition disk 32 and the pointer 35, the angle can be recorded more clearly, and thus the second bracket 8 can be reset very conveniently.

[0031] Working principle: When the model car door bridge structure needs to be used, when the door bridge is needed, the driving part 1 is connected to the driving machine, so that the two bevel gears inside the transmission component 4 are engaged and driven. Then, one of the bevel gears drives the rotating shaft 5 to rotate, so that the small gear 6 rotates and drives the large gear 7 to rotate, thus driving the wheels to rotate and making the model car move. When it is necessary to lubricate the connection between the adjusting rod 9 and the second bracket 8, when the adjusting rod 9 rotates inside the second bracket 8, it drives the fixed rod 21 to rotate, so that the pressing plate 22 drives the rubber block 23 to press the upper half of the lubricating tank 24. Then, the sliding plate 25 inside the lubricating tank 24 is pushed downward by the gas between the lubricating tank 24 and the sliding plate 25, and then the lubricating oil is pushed out of the lubricating tank 24, so that the lubricating oil lubricates the connection between the adjusting rod 9 and the second bracket 8 through the discharge pipe. Under the action of the second spring 29, the second telescopic rod 27 can be reset after being pressed, so that the arc plate 28 supports the upper half of the lubricating tank 24, and then resets the sliding plate 25, thus achieving the lubrication effect. When it is necessary to identify the angle between the first bracket 10 and the second bracket 8, the probe of the angle identification sensor 31 is inserted into the connection between the first bracket 10 and the second bracket 8 for angle identification. Under the action of the angle identification disc 32 and the pointer 35, the angle can be recorded more clearly, and then the second bracket 8 can be reset conveniently. Under the action of the receiver 34 and the inductor 33, the adjusted angle between the first bracket 10 and the second bracket 8 can be accurately identified, thus achieving the angle identification effect.
