[0003] The conventional electric tricycle motor heat abstractor mostly adopts simple air cooling mode, and only relies on the fan with fixed rotating speed to heat dissipation, and has obvious limitation, on the one hand, the fan rotating speed is constant, cannot be flexibly adjusted according to the real-time heating condition of the motor, when the motor is in light load operation, and the heat production is less, the fan still runs with fixed high power, causes unnecessary energy waste and equipment wear and tear, and in the working condition that the motor is heavy load, and the heat production increases greatly, the fan with fixed rotating speed is difficult to provide sufficient heat dissipation capacity, so that the motor temperature is too high, and then causes problems such as insulation material aging and winding resistance increase, seriously affects the service life and working efficiency of the motor, therefore, we provide an electric tricycle motor heat abstractor to solve the above problems.

[0013] This device continuously circulates coolant via a water-cooled circulating pump. Through close contact between the water-cooling pipes and the heat-conducting plate, it rapidly and efficiently absorbs the large amount of heat generated by the drive motor. The coolant is then cooled by a chiller, ensuring continuous heat dissipation. When the temperature sensor detects that the motor temperature is too high, it triggers the air-cooling system. The drive motor drives the cooling fan blades to introduce external cool air for further cooling. Working together, these two systems keep the drive motor temperature within a suitable range. This excellent heat dissipation effectively protects the drive motor. Stable operating temperature prevents problems such as insulation aging and increased winding resistance caused by overheating, extending motor lifespan, reducing maintenance frequency and costs, ensuring the stability and reliability of the electric tricycle's power output, and improving overall vehicle performance and operational safety.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 In this utility model, a heat dissipation device for an electric tricycle motor includes a drive box 3. A water-cooled circulating pump 4 is connected to the right side of the drive box 3, and a cooler 401 is also connected to the right side of the drive box 3. A water-cooling pipe 402 is connected to the inner bottom wall of the drive box 3, and a heat-conducting plate 403 is connected to the inner wall of the drive box 3. The bottom surface of the heat-conducting plate 403 is in contact with the water-cooling pipe 402. One end of the water-cooling pipe 402 is connected to the input end of the water-cooled circulating pump 4, and the other end of the water-cooling pipe 402 is connected to the output end of the cooler 401. The input end of the cooler 401 is connected to the output end of the water-cooled circulating pump 4. A drive motor 8 is connected to the upper surface of the heat-conducting plate 403, and a temperature sensor 9 is connected to the upper surface of the drive motor 8. The temperature sensor 9 provides real-time temperature control. The temperature of the drive motor 8 is monitored and fed back to the internal controller. The water-cooled circulation pump 4 works continuously, and the coolant circulates between the water-cooling pipe 402, the water-cooled circulation pump 4, and the refrigerator 401, continuously removing the heat transferred from the drive motor 8 to the heat conduction plate 403. If the temperature sensor 9 detects that the temperature of the drive motor 8 has risen to the set air-cooling start threshold, the control system issues a command to start the drive motor 504 at the heat dissipation port 5, which drives the cooling fan blades 505 to rotate for air cooling. The two work together to keep the temperature of the drive motor 8 within a suitable range. The good heat dissipation effect effectively protects the drive motor 8, and the stable operating temperature can avoid problems such as insulation aging and increased winding resistance caused by overheating of the motor.

[0021] The bottom surface of the drive box 3 is connected to a base plate 1. Two mounting blocks 2 are connected to both the front and back of the base plate 1. A rubber pad 6 is connected to the bottom surface of the base plate 1. The rubber pad 6 improves the installation stability of the device. The inner wall of the drive box 3 is connected to a limit assembly 7. A first limit bushing 701 is embedded in the inner wall of the limit assembly 7, and a second limit bushing 702 is embedded in the inner wall of the drive box 3. The combination of the above structures improves the structural strength of the equipment. The output end of the drive motor 8 is connected to a transmission rod 703. The end of the transmission rod 703 away from the drive motor 8 passes through the first limit bushing 701 and the second limit bushing 702 in sequence and extends to the outside of the drive box 3. The end of the transmission rod 703 away from the drive motor 8 is connected to a connecting flange 704. The connecting flange 704 allows the transmission rod 703 to be quickly connected or separated from external transmission components.

[0022] The inner wall of the drive box 3 has two heat dissipation vents 5, and the upper surface of the drive box 3 has a heat dissipation top opening 501. The upper surface of the heat dissipation top opening 501 is connected to a dust cover 502 by bolts. The dust cover 502 can improve the dust prevention performance of the equipment. Each heat dissipation vent 5 has a heat dissipation mounting bracket 503 connected to the side away from each other. Each heat dissipation mounting bracket 503 has a set of drive motors 504 connected to the inner wall. Each drive motor 504 has a set of heat dissipation fan blades 505 connected to the output end. Through the cooperation of the above structures, the temperature control performance of this device can be improved.

[0023] The working principle of this utility model is as follows:

[0024] In use, the entire device is first fixed to the electric tricycle. When the electric tricycle is started, the drive motor 8 starts to work and generates heat. The temperature sensor 9 monitors the temperature of the drive motor 8 in real time and feeds the temperature signal back to the internal controller. The water-cooled circulation pump 4 works continuously, and the coolant circulates between the water-cooling pipe 402, the water-cooled circulation pump 4 and the cooler 401, continuously carrying away the heat transferred from the drive motor 8 to the heat conduction plate 403. If the temperature sensor 9 detects that the temperature of the drive motor 8 has risen to the set air-cooling start threshold, the control system issues a command to start the drive motor 504 at the heat dissipation port 5, which drives the cooling fan blades 505 to rotate for air cooling, assisting the water cooling system in reducing the temperature of the drive motor 8 and ensuring that the drive motor 8 works stably within a suitable temperature range.
