Description

Technical Field

[0001] This invention belongs to the field of electric tricycle motor technology, specifically an electric tricycle motor protection component. Background Technology

[0002] Electric tricycles are tricycles powered by batteries. They have a certain carrying capacity and are widely used in transportation in factories, homes, and by individual tenants due to their low price, flexibility, and ease of maintenance.

[0003] In addition to the battery, the drive motor is also one of the core components of an electric tricycle. Currently, most electric tricycle motors are exposed without any effective protection mechanism. Some transportation routes have complex road conditions, often with deep potholes, sharp rocks, etc. Electric tricycles are prone to motor damage when traveling on such roads. Therefore, this invention provides an electric tricycle motor protection component. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: An electric tricycle motor protection component of this invention includes a motor body, which is a permanent magnet synchronous motor. A protective plate is provided on the outside of the motor body. A connecting block is fixed to the side of the motor body near the protective plate, and a pressing block is fixed to the side of the connecting block away from the motor body. A buffer spring is fixed between the pressing block and the protective plate. During operation, the permanent magnet synchronous motor has the advantages of high torque and low noise. In use, the motor body is mounted on the bottom of the tricycle, and the protective plate is connected to the floor of the tricycle. During the tricycle's operation, if a large pothole or bump appears on the road surface, and the driver is unable to avoid it, the protective plate will contact the pothole or bump first, thus protecting the motor body. Simultaneously, the protective plate will compress the buffer spring, causing it to deform and buffer the impact force. This effectively protects the electric tricycle motor from damage caused by collisions during normal operation, thus improving the service life of the electric tricycle.

[0006] Preferably, the buffer spring has a compression rod inside, which is fixedly connected to the protective plate. A hollow column is slidably connected to the outside of the compression rod. A return pipe is fixed inside the connecting block. The inlet and outlet of the return pipe are both located inside the hollow column, and a one-way valve is installed at both the inlet and outlet of the return pipe. Water is stored between the hollow column and the compression rod. During operation, when a collision occurs, the protective plate compresses the buffer spring and simultaneously drives the compression rod to slide inside the hollow column. As the compression rod slides inside the hollow column, it simultaneously forces the water inside the hollow column into the return pipe. This achieves a damping and shock absorption effect, preventing excessive impact force from causing the buffer spring to rebound repeatedly and causing the protective plate to continuously impact the ground and suffer significant wear. After the water inside the hollow column is forced into the return pipe, the water flows through the return pipe and simultaneously cools the connecting block, which in turn cools the motor body, thus reducing the operating temperature of the motor body.

[0007] Preferably, the protective plate has multiple heat dissipation holes inside, and T-shaped closing plates are provided on both sides of the inner wall of the heat dissipation holes. An expansion column is fixed on the side of the T-shaped closing plate away from the heat dissipation holes. A water guide hole is provided inside the protective plate on the side of the expansion column away from the motor body. During operation, the multiple heat dissipation holes inside the protective plate can ensure the heat dissipation needs of the motor under normal driving conditions of the tricycle. However, if the electric tricycle is traveling in the rain and falls into a deep pit with water accumulation, the water in the pit will flow into the expansion column through the water guide hole, causing the expansion column to expand. The expanded expansion column will push the T-shaped closing plates to slide until the two T-shaped closing plates contact each other, thus sealing the heat dissipation holes. This automatically seals the pit after the electric tricycle falls into a deep pit with water accumulation, preventing water from directly contacting the motor. It should be noted that the expansion column is made of a material that absorbs water, expands, and shrinks after dehydration.

[0008] Preferably, a return spring is fixed between the pair of T-shaped closing plates, and each pair of T-shaped closing plates has a storage groove adapted to the return spring. A rubber pad is fixed on the side of the pair of T-shaped closing plates that are close to each other. During operation, as the T-shaped closing plates move, they will simultaneously compress the return spring and deform it until the return spring retracts into the storage groove. After the tricycle drives out of the deep pit, under the action of the return spring's rebound force, the two T-shaped closing plates will gradually return to their original positions, thereby preventing the protective plate from remaining closed and causing heat dissipation problems for the motor body. The rubber pad allows the two T-shaped closing plates to close more tightly.

[0009] Preferably, the protective plate is rotatably connected to multiple guide wheels, which are made of high-hardness metal material. During operation, after the electric tricycle falls into a deep pit or collides with a ground protrusion, the guide wheels will come into contact with the pit or protrusion. Then, during the tricycle's travel, the guide wheels will rotate, thereby accelerating the tricycle's escape from the pit or separation from the ground protrusion.

[0010] Preferably, waterproof plates are provided on both sides of the buffer spring, and the waterproof plates are fixedly connected to the protective plate. During operation, if the tricycle falls into a deep pit with water accumulation, some heat dissipation holes may not be closed in time, causing some water to enter the interior of the protective plate. The waterproof plates can effectively prevent sewage from directly contacting the buffer spring and the compression rod, thereby preventing corrosion of the buffer spring and the compression rod, thus effectively improving the service life of the equipment.

[0011] Preferably, both the extrusion block and the hollow column have water inlet holes, and the two water inlet holes cooperate with each other. A guide pipe is fixed to the end of the water inlet hole away from the extrusion block, and a filter pipe is fixed to the end of the guide pipe away from the extrusion block. The filter pipe is fixedly connected to the waterproof plate. During operation, when the extrusion rod slides inside the hollow column, during the reset process of the buffer spring, the extrusion rod will draw water out of the return pipe. When the water level inside the hollow column is too low, the extrusion rod will simultaneously apply a suction force to the filter pipe through the guide pipe after drawing water out of the return pipe, thereby drawing the water accumulated inside the protective plate into the hollow column to replenish the water in the hollow column and improve the service life of the equipment.

[0012] Preferably, a sealing plate is slidably connected inside the hollow column, and a float is fixed to the end of the sealing plate away from the extrusion rod. It should be noted that in the initial state, the water level inside the hollow column is higher than the position of the water inlet hole. Therefore, under the action of buoyancy, the float will drive the sealing plate to slide upward and block the water inlet hole. This can effectively seal and preserve the water inside the hollow column and prevent excessive evaporation.

[0013] Preferably, a drainage hole is provided inside the protective plate and on the side of the waterproof plate away from the buffer spring. The diameter of the drainage hole is smaller than the diameter of the guide pipe. During operation, the drainage hole allows residual water inside the protective plate to be slowly discharged without affecting the water absorption operation of the filter pipe.

[0014] Preferably, a plurality of elastic sheets are fixed to the side of the waterproof plate near the buffer spring, and a striking ball is fixed to the end of the elastic sheet away from the waterproof plate. During operation, when the tricycle falls into a deep pit or collides with a ground protrusion, the striking ball on the outside of the waterproof plate will cause the elastic sheet to deform under the action of inertial force and repeatedly strike the waterproof plate, thereby generating a rapid alarm sound to remind the driver to stop in time to observe the condition under the vehicle, judge the specific road conditions, and avoid blind driving that may cause vehicle damage or rollover.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The electric tricycle motor protection component of the present invention protects the motor body by first contacting the protective plate with the dent or protrusion. At the same time, the protective plate compresses the buffer spring during the process to deform it and buffer the impact force. In this way, the motor of the electric tricycle can be effectively protected from damage caused by bumps during normal operation, thereby improving the service life of the electric tricycle.

[0017] 2. The electric tricycle motor protection component of the present invention uses a squeezing rod to slide inside a hollow column, squeezing water inside the hollow column into a return pipe, thus achieving a damping and shock absorption effect. After the water inside the hollow column is squeezed into the return pipe, the water will simultaneously cool the connecting block during the flow of water in the return pipe, thereby cooling the motor body through the connecting block, thus reducing the operating temperature of the motor body.

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Example 1

[0029] like Figures 1 to 3 As shown in the embodiment of the present invention, an electric tricycle motor protection component includes a motor body 1, which is a permanent magnet synchronous motor. A protective plate 2 is provided on the outside of the motor body 1. A connecting block 3 is fixed on the side of the motor body 1 near the protective plate 2, and a pressing block 4 is fixed on the side of the connecting block 3 away from the motor body 1. A buffer spring 5 is fixed between the pressing block 4 and the protective plate 2. During operation, the permanent magnet synchronous motor has the advantages of high torque and low noise. In use, the motor body 1 is installed at the bottom of the tricycle, and the protective plate 2 is connected to the floor of the tricycle. During the operation of the tricycle, if a large pothole or bump appears on the road, and the driver is unable to avoid it, the protective plate 2 will contact the pothole or bump first, thereby protecting the motor body 1. At the same time, the protective plate 2 will compress the buffer spring 5 to deform it, thereby buffering the impact force. In this way, the motor of the electric tricycle can be effectively protected from damage caused by bumps during normal operation, thus improving the service life of the electric tricycle.

[0030] like Figures 2 to 3As shown, the buffer spring 5 has a compression rod 6 inside, which is fixedly connected to the protective plate 2. A hollow column 7 is slidably connected to the outside of the compression rod 6. A return pipe 8 is fixed inside the connecting block 3. The inlet and outlet of the return pipe 8 are both located inside the hollow column 7, and a one-way valve is installed at both the inlet and outlet of the return pipe 8. Water is stored between the hollow column 7 and the compression rod 6. During operation, in the process of collision, the protective plate 2 compresses the buffer spring 5 and simultaneously drives the compression rod 6 to slide inside the hollow column 7. As the extrusion rod 6 slides inside the hollow column 7, it simultaneously forces the water inside the hollow column 7 into the return pipe 8. This achieves a damping and shock absorption effect, preventing excessive impact force from causing the buffer spring 5 to reciprocate and rebound, resulting in the protective plate 2 continuously impacting the ground and causing significant wear. After the water inside the hollow column 7 is forced into the return pipe 8, the water will simultaneously cool the connecting block 3 as it flows through the return pipe 8. This, in turn, cools the motor body 1 through the connecting block 3, thereby reducing the operating temperature of the motor body 1.

[0031] like Figures 2 to 4 As shown, the protective plate 2 has multiple heat dissipation holes inside. T-shaped closing plates 10 are provided on both sides of the inner wall of the heat dissipation holes. An expansion column 9 is fixed on the side of the T-shaped closing plate 10 away from the heat dissipation holes. A water guide hole 13 is provided inside the protective plate 2 on the side of the expansion column 9 away from the motor body 1. During operation, the multiple heat dissipation holes inside the protective plate 2 can ensure the heat dissipation needs of the motor under normal driving conditions of the tricycle. However, if the electric tricycle is traveling in the rain and falls into a deep pit with water accumulation, the water in the pit will flow into the expansion column 9 through the water guide hole 13, causing the expansion column 9 to expand. The expanded expansion column 9 will push the T-shaped closing plate 10 to slide until the two T-shaped closing plates 10 contact each other, thus sealing the heat dissipation holes. This automatically seals the pit after the electric tricycle falls into the deep pit with water accumulation, preventing water from directly contacting the motor. It should be noted that the expansion column 9 is made of a material that absorbs water, expands, and shrinks after dehydration.

[0032] like Figure 4 As shown, a return spring 12 is fixed between the pair of T-shaped closing plates 10. Each pair of T-shaped closing plates 10 has a storage groove adapted to the return spring 12. A rubber pad 11 is fixed on the side of the pair of T-shaped closing plates 10 that are close to each other. During operation, as the T-shaped closing plates 10 move, they will simultaneously compress the return spring 12 and deform it until the return spring 12 retracts into the storage groove. After the tricycle drives out of the pit, under the action of the rebound force of the return spring 12, the two T-shaped closing plates 10 will gradually return to their original position, thereby preventing the protective plate 2 from remaining closed and causing heat dissipation problems in the motor body 1. The rubber pad 11 can make the two T-shaped closing plates 10 close more tightly.

[0033] like Figure 4 As shown, the protective plate 2 is rotatably connected to a plurality of guide wheels 14, which are made of high-hardness metal material. When in operation, after the electric tricycle falls into a deep pit or collides with a ground protrusion, the guide wheels 14 will come into contact with the pit or protrusion. Then, during the tricycle's travel, the guide wheels 14 will rotate, thereby accelerating the tricycle to get out of the pit or separate from the ground protrusion.

[0034] like Figure 3 As shown, waterproof plates 15 are provided on both sides of the buffer spring 5, and the waterproof plates 15 are fixedly connected to the protective plate 2. During operation, after the tricycle falls into a deep pit with water accumulation, some heat dissipation holes may not be closed in time, causing some water to enter the interior of the protective plate 2. The waterproof plates 15 can effectively prevent sewage from directly contacting the buffer spring 5 and the compression rod 6, thereby preventing corrosion of the buffer spring 5 and the compression rod 6. This can effectively improve the service life of the equipment.

[0035] like Figure 3 As shown, both the extrusion block 4 and the hollow column 7 have water inlet holes, and the two water inlet holes cooperate with each other. A guide pipe 17 is fixed to the end of the water inlet hole away from the extrusion block 4, and a filter pipe 16 is fixed to the end of the guide pipe 17 away from the extrusion block 4. The filter pipe 16 is fixedly connected to the waterproof plate 15. During operation, when the extrusion rod 6 slides inside the hollow column 7, during the reset process of the buffer spring 5, the extrusion rod 6 will draw water out of the return pipe 8. When the water level inside the hollow column 7 is too low, the extrusion rod 6 will simultaneously apply a suction force to the filter pipe 16 through the guide pipe 17 after drawing water out of the return pipe 8, thereby drawing the water accumulated inside the protective plate 2 into the hollow column 7 to replenish the water in the hollow column 7 and improve the service life of the equipment.

[0036] like Figure 5 As shown, a sealing plate 18 is slidably connected inside the hollow column 7, and a float 19 is fixed to the end of the sealing plate 18 away from the extrusion rod 6. It should be noted that in the initial state, the water level inside the hollow column 7 is higher than the position of the water inlet hole. Therefore, under the action of buoyancy, the float 19 will drive the sealing plate 18 to slide upward and block the water inlet hole. In this way, the water inside the hollow column 7 can be effectively sealed and preserved to prevent excessive evaporation.

[0037] like Figure 3 As shown, a drain hole 20 is provided inside the protective plate 2 and on the side of the waterproof plate 15 away from the buffer spring 5. The diameter of the drain hole 20 is smaller than the diameter of the guide pipe 17. During operation, the drain hole 20 allows the residual water inside the motor body 1 to be slowly discharged without affecting the water suction operation of the filter pipe 16.

[0038] Example 2

[0039] like Figures 6 to 7 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a plurality of elastic sheets 21 are fixed on the side of the waterproof plate 15 near the buffer spring 5, and a striking ball 22 is fixed on the end of the elastic sheet 21 away from the waterproof plate 15; during operation, after the tricycle falls into a deep pit or collides with a ground protrusion, during the deformation of the protective plate 2, the striking ball 22 on the outside of the waterproof plate 15 will drive the elastic sheet 21 to deform under the action of inertial force and repeatedly strike the waterproof plate 15, thereby generating a rapid alarm sound to remind the driver to stop in time to observe the situation under the vehicle, judge the specific road conditions, and avoid blind driving that may cause vehicle damage or rollover.

[0040] Working principle: It adopts a permanent magnet synchronous motor, which has the advantages of high torque and low noise. When in use, the motor body 1 is installed at the bottom of the tricycle, and the protective plate 2 is connected to the floor of the tricycle. When the tricycle is in motion, if there is a large pothole or bump on the road, and the driver is unable to avoid it, the protective plate 2 will contact the pothole or bump first, thus protecting the motor body 1. At the same time, the protective plate 2 will compress the buffer spring 5 to deform it, thereby buffering the impact force. In this way, the motor of the electric tricycle can be effectively protected from damage caused by bumps during normal driving, thus improving the service life of the electric tricycle.

[0041] During the collision, the protective plate 2 compresses the buffer spring 5 while simultaneously causing the squeezing rod 6 to slide within the hollow column 7. As the squeezing rod 6 slides within the hollow column 7, it forces the water inside into the return pipe 8. This damping effect prevents excessive impact from causing the buffer spring 5 to repeatedly rebound, resulting in significant wear from continuous impacts between the protective plate 2 and the ground. Furthermore, the water flowing through the return pipe 8 cools the connecting block 3, thereby reducing its temperature. The motor body 1 is cooled down, reducing its operating temperature. The multiple heat dissipation holes inside the protective plate 2 ensure the motor's heat dissipation needs are met during normal driving. However, if the electric tricycle is traveling in the rain and falls into a deep, water-filled pit, the water will flow into the expansion column 9 through the water guide hole 13, causing the expansion column 9 to expand. The expanded expansion column 9 will then push the T-shaped closing plate 10 to slide until the two T-shaped closing plates 10 contact each other, thus sealing the heat dissipation holes. This prevents damage after the electric tricycle falls into the water-filled pit. The automatic sealing prevents direct contact between water and the motor. It should be noted that the expansion column 9 is made of a material that absorbs water, expands, and contracts upon dehydration. During the movement of the T-shaped closing plate 10, it simultaneously compresses the return spring 12, causing it to deform until the return spring 12 retracts into the storage groove. After the tricycle leaves the pit, the rebound force of the return spring 12 gradually returns the two T-shaped closing plates 10 to their original positions, preventing the protective plate 2 from remaining closed and causing heat dissipation problems for the motor body 1. The rubber pad 11 further ensures a tighter seal between the two T-shaped closing plates 10. When a tricycle falls into a deep pit or collides with a ground protrusion, the guide wheel 14 will come into contact with the pit or protrusion. Then, during the tricycle's movement, the guide wheel 14 will rotate, thereby accelerating the tricycle's escape from the pit or separation from the ground protrusion. When a tricycle falls into a deep pit with accumulated water, some of the heat dissipation holes may not be closed in time, causing some water to enter the interior of the protective plate 2. The waterproof plate 15 can effectively prevent sewage from directly contacting the buffer spring 5 and the compression rod 6, thus preventing corrosion of the buffer spring 5 and the compression rod 6. This effectively improves the service life of the equipment.

[0042] When the squeezing rod 6 slides inside the hollow column 7, during the reset process of the buffer spring 5, the squeezing rod 6 will draw water out of the return pipe 8. When the water level inside the hollow column 7 is too low, the squeezing rod 6 will simultaneously apply a suction force to the filter pipe 16 through the guide pipe 17 after drawing water out of the return pipe 8, thereby drawing water accumulated inside the motor body 1 into the hollow column 7 to replenish the water inside the hollow column 7 and improve the service life of the equipment. It should be noted that in the initial state, the water level inside the hollow column 7 is higher than the position of the water replenishment hole. Therefore, under the action of buoyancy, the float ball 19 will drive the sealing plate 18 to slide upward to block the water replenishment hole. This can effectively seal and preserve the water inside the hollow column 7 and prevent excessive evaporation. The setting of the drain hole 20 allows the residual water inside the protective plate 2 to be slowly discharged without affecting the water suction operation of the filter pipe 16.

[0043] After the tricycle falls into a deep pit or collides with a protruding part of the ground, during the deformation of the protective plate 2, the striking ball 22 on the outside of the waterproof plate 15 will cause the elastic sheet 21 to deform under the action of inertial force and repeatedly strike the waterproof plate 15, thereby generating a rapid alarm sound to remind the driver to stop in time to observe the situation under the vehicle, judge the specific road conditions, and avoid blind driving that could lead to vehicle damage or rollover.
