Description

Technical Field

[0001] This utility model relates to the field of electric motorcycle motors, and in particular to an electric motorcycle motor. Background Technology

[0002] An electric motorcycle motor is an electric motor used to drive an electric motorcycle. It is powered by a battery, converting electrical energy into mechanical energy to propel the motorcycle's wheels forward.

[0003] Electric motorcycle motors are powered by batteries. The current flowing through the stator windings generates a magnetic field, which interacts with the magnetic field on the rotor to produce electromagnetic force that drives the rotor to rotate. The rotation of the rotor is transmitted to the wheels through a mechanical transmission system, enabling the motorcycle to move forward. The electronic control system adjusts the current to precisely control the speed and torque of the motor body, ensuring the electric motorcycle runs smoothly and efficiently. However, the current generates resistance heat, and the internal mechanical components of the motor body also generate heat due to friction during rotation. This makes the motor body prone to overheating and damage during use, reducing its lifespan. Utility Model Content

[0004] The technical problem this invention aims to solve is that the passage of current generates resistance heat, and the mechanical components inside the motor body also generate heat due to friction during rotation, making the motor body prone to overheating damage during use and reducing its service life.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an electric motorcycle motor, including a motor body, and a cooling device is provided on the outer surface of the motor body. The cooling device can cool the surface of the water tank through a semiconductor cooling chip, so that when the water inside comes into contact with the water tank, heat exchange occurs and the temperature is reduced. Then, the water is guided to the inner wall of the U-shaped tube to cool the surface of the motor body, thereby achieving the effect of preventing overheating damage.

[0006] Preferably, the cooling device includes a water tank, one side of which is fixedly mounted on one side of the motor body; a semiconductor cooling chip, one side of which is fixedly mounted on one side of the water tank; a micro water pump, the inlet of which is installed through the water tank on one side; a first ring tube frame, one end of which is fixedly mounted on one side of the outlet of the micro water pump; a second ring tube frame, one end of which is installed through the water tank on one side; and a plurality of U-shaped tubes, the two ends of which are respectively installed through the first and second ring tube frames on one side, and one side is in close contact with the outer surface of the motor body.

[0007] The aforementioned components achieve the following effects: By incorporating a cooling device, when the motor body is mounted on the electric motorcycle, the motor body receives electrical energy from the battery. The current flowing through the stator windings generates a magnetic field, which interacts with the magnetic field on the rotor, producing electromagnetic force that drives the rotor to rotate. The rotor's rotation is transmitted to the wheels via a mechanical transmission system, propelling the motorcycle forward. The electronic control system adjusts the current to precisely control the motor body's speed and torque, ensuring smooth and efficient operation of the electric motorcycle. During motor body operation, the semiconductor cooling chip can be energized to cool the inner wall of the water tank. The process involves the water being poured into the tank, where it exchanges heat with the inner wall of the tank to lower its temperature. A micro water pump then pumps the cooled water into the first ring pipe frame, and finally distributes it into the inner walls of several U-shaped tubes to reduce the surface temperature of the U-shaped tubes. This allows for heat exchange with the motor body surface, further lowering its temperature. The water is then transported from the other end to the inner wall of the second ring pipe frame, flowing back into the tank for continuous cooling. This efficient and stable cooling process effectively and stably reduces the motor body temperature, preventing overheating that could lead to performance degradation or component damage, and extending the motor's lifespan.

[0008] Preferably, a plurality of limiting frames are fixedly installed on the outer surface of the motor body, wherein one end of the U-shaped tube is inserted into the inner wall of the limiting frame.

[0009] The effect achieved by the above components is that by setting a limiting frame, the outer surface of one end of the U-shaped tube can be limited and fixed, making it less prone to shaking during use.

[0010] Preferably, the cooling device further includes several elastic rubber blocks, wherein one side of the elastic rubber block is fixedly installed at an angle on the inner wall of one end of the U-shaped tube near the first ring tube frame.

[0011] The effect achieved by the above components is as follows: by setting up elastic rubber blocks, the inlet of the first ring pipe rack can be initially sealed. In this way, after the micro water pump draws the cooled water into the first ring pipe rack, the water will not flow into the U-shaped pipes before it is filled to a certain pressure. Only when the cooling water completely fills the first ring pipe rack and the pressure increases will the elastic rubber block be pushed open and deformed, so that the cooling water is evenly distributed to the inner walls of several U-shaped pipes. This can make the water temperature on the inner wall of each U-shaped pipe uniform, achieving a uniform cooling effect.

[0012] Preferably, a plurality of brackets are fixedly installed on one side of the motor body, and the two ends of the brackets are respectively fixedly installed on one side of the first ring tube frame and the second ring tube frame.

[0013] The effect achieved by the above components is that by setting up the bracket, the first ring tube frame and the second ring tube frame can be supported and fixed on one side of the motor body, which is less likely to shake and be damaged, thus improving the stability of use.

[0014] Preferably, the outer surface of the second ring tube frame is provided with a protective mechanism, wherein the protective mechanism includes a ring block, wherein the inner wall of the ring block is fixedly installed on the outer surface of the second ring tube frame, and a locking hole is symmetrically opened on one side of the ring block; a protective cover, wherein a locking rod is symmetrically and rotatably installed on one side of the protective cover, wherein the inner wall of the protective cover is sleeved on the outer surface of the motor body and several U-shaped tubes, and two locking rods on one side are respectively inserted into two locking holes.

[0015] The effect achieved by the above components is as follows: by setting up a protective mechanism, after the cooling device is installed, the clamp can be rotated to a certain angle, and then its protective cover can be placed on the outer surface of the motor body and several U-shaped tubes. The two clamps are inserted into the two clamp holes respectively, and then rotated to a certain angle, so that the protective cover can be installed on one side of the annular block to protect the outer surface of the motor body and the U-shaped block and improve the service life of both.

[0016] Preferably, the protective mechanism further includes two torsion springs, wherein the inner wall of the torsion spring is sleeved on the outer surface of one end of the lever, and the two ends are respectively fixedly installed on one side of the lever and one side of the protective cover.

[0017] The effect achieved by the above components is as follows: by setting a torsion spring, when the locking rod is rotated to a certain angle, the torsion spring will be deformed. After being locked into the locking hole, the torsion spring will drive the locking rod to return to its original position in the locking hole, making the locking more secure and less prone to loosening.

[0018] Preferably, the protective mechanism further includes a plurality of reinforcing rods, wherein the outer surface of the reinforcing rods is fixedly installed in the inner wall of the protective cover.

[0019] The effect achieved by the above components is that by setting up reinforcing rods, the compressive strength and compressive strength of the protective cover can be increased, making it more secure in protecting the outer surface of the motor body and the U-shaped tube.

[0020] The beneficial effects of this utility model are: By incorporating a cooling device, when the motor body is mounted on an electric motorcycle, the semiconductor cooling chip is energized to cool the inner wall of the water tank. Water inside the tank then exchanges heat with the inner wall, lowering its temperature. A micro water pump then pumps the cooled water into the first ring pipe frame, and finally distributes it into the inner walls of several U-shaped tubes, reducing the surface temperature of the U-shaped tubes. This allows for heat exchange with the motor body surface, further lowering its temperature. Finally, the water is transported from the other end to the inner wall of the second ring pipe frame, flowing back into the water tank for cyclic cooling. This efficient and stable cooling system effectively and stably reduces the motor body temperature, preventing overheating-induced performance degradation or component damage, and extending the motor's lifespan.

For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0025] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] In this embodiment: Figures 1-7 The electric motor shown includes a motor body 1. A cooling device 2 is provided on the outer surface of the motor body 1. The cooling device 2 can cool the surface of the water tank 21 through a semiconductor cooling chip 22, so that when the water inside comes into contact with the water tank 21, heat exchange occurs and the temperature is reduced. Then, the water is guided to the inner wall of the U-shaped tube 26 to cool the surface of the motor body 1, thereby achieving the effect of preventing overheating damage.

[0027] Figures 1-7 The cooling device 2 shown includes a water tank 21, one side of which is fixedly mounted on one side of the motor body 1; a semiconductor cooling chip 22 (model TEC1-12706), one side of which is fixedly mounted on one side of the water tank 21; a micro water pump 23 (model JN-300), the inlet of which is installed through one side of the water tank 21; a first ring tube frame 24, one end of which is fixedly mounted on one side of the outlet of the micro water pump 23; a second ring tube frame 25, one end of which is installed through one side of the water tank 21; and several U-shaped tubes 26, the two ends of which are respectively installed through one side of the first ring tube frame 24 and the second ring tube frame 25, and one side is in close contact with the outer surface of the motor body 1. By setting up the cooling device 2, when the motor body 1 is installed on the electric motorcycle for use, the motor body 1 is powered by a battery. The current flows through the stator windings to generate a magnetic field, which interacts with the magnetic field on the rotor to generate electromagnetic force to drive the rotor to rotate. The rotation of the rotor is transmitted to the wheels through the mechanical transmission system, enabling the motorcycle to move forward. The electronic control system adjusts the current to precisely control the speed and torque of the motor body 1, ensuring the smooth and efficient operation of the electric motorcycle. During the use of the motor body 1, the semiconductor cooling chip 22 can be energized to cool the inner wall of the water tank 21 before being installed inside the water tank 21. The water will come into contact with the inner wall of the water tank 21, undergoing heat exchange to lower its temperature. Then, the micro water pump 23 will be activated to pump the cooled water from the water tank 21 into the interior of the first ring pipe frame 24. Finally, the water will be distributed into the inner walls of several U-shaped pipes 26, lowering the surface temperature of the U-shaped pipes 26. This will cause heat exchange when the U-shaped pipes 26 come into contact with the surface of the motor body 1, further lowering the surface temperature of the motor body 1. Finally, the water will be transported from the other end to the inner wall of the second ring pipe frame 25, flowing back to the inner wall of the water tank 21 for circulating cooling. This efficiently and stably lowers the temperature of the motor body 1, preventing performance degradation or component damage due to overheating and extending the motor's service life. It should be noted that the semiconductor cooling chip 22 and the micro water pump 23 are mature technologies and equipment in the prior art, and their internal structure, connection method, and principle will not be described further.

[0028] Figures 1-7Several limiting brackets 27 are fixedly installed on the outer surface of the motor body 1 shown, with one end of the U-shaped tube 26 inserted into the inner wall of the limiting bracket 27. By setting the limiting brackets 27, the outer surface of one end of the U-shaped tube 26 can be limited and fixed, making it less prone to shaking during use. The cooling device 2 also includes several elastic rubber blocks 210, with one side of the elastic rubber block 210 fixedly installed at an angle on the inner wall of the end of the U-shaped tube 26 near the first annular tube frame 24. By setting the elastic rubber block 210, the inlet of the first ring pipe frame 24 can be initially sealed. This prevents water from flowing into the U-shaped pipes 26 until the micro water pump 23 draws cooled water into the first ring pipe frame 24 and reaches a certain pressure. Only when the cooling water completely fills the first ring pipe frame 24 and the pressure increases will the elastic rubber block 210 be forced open, causing it to deform and evenly distribute the cooling water to the inner walls of the U-shaped pipes 26. This ensures a uniform water temperature on the inner wall of each U-shaped pipe 26, achieving a uniform cooling effect. Several brackets 28 are fixedly installed on one side of the motor body 1. The two ends of the brackets 28 are respectively fixed to one side of the first ring pipe frame 24 and the second ring pipe frame 25. By setting the brackets 28, the first ring pipe frame 24 and the second ring pipe frame 25 can be supported and fixed to one side of the motor body 1, preventing shaking and damage, and improving operational stability.

[0029] Figures 1-7 The outer surface of the second ring tube frame 25 shown is provided with a protective mechanism 29, wherein the protective mechanism 29 includes an annular block 291, wherein the inner wall of the annular block 291 is fixedly installed on the outer surface of the second ring tube frame 25, and a locking hole 292 is symmetrically opened on one side of the annular block 291; a protective cover 293, wherein a locking rod 294 is symmetrically rotatably installed on one side of the protective cover 293, wherein the inner wall of the protective cover 293 is sleeved on the outer surface of the motor body 1 and several U-shaped tubes 26, and two locking rods 294 on one side are respectively inserted into two locking holes 292. By setting up the protective mechanism 29, after the cooling device 2 is installed, the clamping rod 294 can be rotated to a certain angle, and then its protective cover 293 can be fitted onto the outer surface of the motor body 1 and several U-shaped tubes 26. The two clamping rods 294 are respectively inserted into the two clamping holes 292, and then rotated to a certain angle, so that the protective cover 293 can be installed on one side of the annular block 291 to protect the outer surface of the motor body 1 and the U-shaped block and improve their service life.

[0030] Figures 1-7The protective mechanism 29 also includes two torsion springs 295, the inner walls of which are fitted onto the outer surface of one end of the locking rod 294, and both ends are fixedly installed on one side of the locking rod 294 and one side of the protective cover 293, respectively. By providing the torsion springs 295, when the locking rod 294 is rotated to a certain angle, the torsion springs 295 deform. After being engaged in the locking hole 292, the torsion springs 295 will cause the locking rod 294 to return to its original position within the locking hole 292, making the engagement more secure and less prone to loosening. The protective mechanism 29 also includes several reinforcing rods 296, the outer surfaces of which are fixedly installed in the inner wall of the protective cover 293. By providing the reinforcing rods 296, the compressive strength and rigidity of the protective cover 293 can be increased, making it more secure in protecting the outer surfaces of the motor body 1 and the U-shaped tube 26.

[0031] Working principle: When the motor body 1 is installed on the electric motorcycle, it is powered by a battery. Current flows through the stator windings, generating a magnetic field that interacts with the magnetic field on the rotor, producing electromagnetic force that drives the rotor to rotate. The rotor's rotation is transmitted to the wheels via a mechanical transmission system, propelling the motorcycle forward. The electronic control system adjusts the current to precisely control the speed and torque of the motor body 1, ensuring smooth and efficient operation of the electric motorcycle. During operation, the semiconductor cooling chip 22 can be energized to cool the inner wall of the water tank 21, allowing the water inside the tank to cool down. The water exchanges heat with the inner wall of the water tank 21 to lower its temperature. Then, the micro water pump 23 is activated to pump the cooled water from the water tank 21 into the interior of the first ring pipe frame 24. Finally, the water is diverted into the inner wall of several U-shaped pipes 26 to lower the surface temperature of the U-shaped pipes 26. This allows the water to exchange heat with the surface of the motor body 1, further lowering the surface temperature of the motor body 1. Finally, the water is transported from the other end to the inner wall of the second ring pipe frame 25 and flows back to the inner wall of the water tank 21 for circulating cooling. This process efficiently and stably lowers the temperature of the motor body 1, preventing performance degradation or component damage caused by overheating and extending the motor's service life.

[0032] After the cooling device 2 is installed, the locking rod 294 can be rotated to a certain angle, causing the torsion spring 295 to deform. Then, its protective cover 293 is fitted onto the outer surface of the motor body 1 and several U-shaped tubes 26. After the two locking rods 294 are inserted into the two locking holes 292 respectively, the torsion spring 295 will drive the locking rods 294 to reset and limit them in the locking holes 292. The protective cover 293 can then be installed on one side of the annular block 291 to protect the outer surface of the motor body 1 and the U-shaped block, thereby improving their service life.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
