Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electric tricycle motors, and more particularly to an electric tricycle motor with dual heat dissipation of water cooling and air cooling. Background Art
[0002] In the field of electric tricycle motors, electric tricycles are used as a means of transportation, and their motors will generate a lot of heat when running for a long time or under heavy load. The traditional heat dissipation method mainly relies on air cooling, that is, using the airflow generated by the fan to take away the heat generated by the motor, which is difficult to meet the needs of efficient heat dissipation and easily causes motor overheating, performance degradation, and even damage. At the same time, with the improvement of electric tricycle performance and the increase in motor power, the traditional air cooling method has been difficult to meet the needs of efficient heat dissipation. Especially in high temperature or harsh environment, when the motor runs for a long time under high load, it will generate a lot of heat. If the heat dissipation is not timely or the effect is not good, it will cause the motor temperature to rise, thereby affecting the performance and life of the motor.
[0003] In order to solve this problem, it is necessary to explore new heat dissipation methods. Among them, water cooling has attracted much attention due to its efficient and stable heat dissipation effect. Water cooling can more effectively remove the heat generated by the motor through the circulation of coolant inside the motor, thereby reducing the temperature of the motor.
[0004] Therefore, how to provide an electric tricycle motor with water-cooling and air-cooling dual heat dissipation that combines the advantages of air cooling and water cooling to more effectively take away the heat generated by the motor, reduce the temperature of the motor, and thus improve the performance and life of the motor is an issue that technical personnel in this field urgently need to solve. Summary of the invention

At the same time, a fan for air cooling and heat dissipation is fixedly installed on the rear side of the motor body.

[0009] Furthermore, the water tank fixedly mounted on one side of the frame body is a square box body, a cooling fan is fixedly arranged on the water tank, and a water inlet is provided on the top of the water tank.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] Combined with Figure 1 and attached Figure 3 As shown:
[0019] The present invention discloses a water-cooled and air-cooled electric tricycle motor, comprising a motor body 1, a temperature sensing device 6 fixedly mounted on the motor body 1, a water tank 3 fixedly mounted on one side of a frame body 100, and a circulating water pump 2 arranged between the water tank 3 and the motor body 1;
[0020] The motor body 1 includes a motor body 101 for providing power and a hollow shell 103 sleeved on the outside of the motor body 101. The hollow shell 103 is used to store water cooling liquid for water cooling and heat dissipation. At the same time, a fan 102 for air cooling and heat dissipation is fixedly installed on the rear side of the motor body 101.
[0021] Combined with Figure 1 As shown:
[0022] In order to further optimize the above technical solution, the motor body 1 is fixedly arranged on one side of the electric vehicle rear axle 200 , and the electric vehicle rear axle 200 is located in the rear area of the frame body 100 .
[0023] The temperature sensing device 6 on the motor body 1 is a temperature sensor, which is a device that can monitor and sense changes in the ambient temperature. In the water-cooled and air-cooled dual-heat dissipation electric tricycle motor, the temperature sensor is installed on the hollow housing 103 outside the motor body 1. The temperature sensor is connected to the circulating water pump through an electric wire, and the temperature sensor can monitor the changes in the motor temperature in real time.
[0024] Combined with Figure 1 and attached Figure 2 As shown:
[0025] In order to further optimize the above technical solution, the water tank 3 fixedly mounted on one side of the frame body 100 is a square box, and a cooling fan 302 is fixedly arranged on the water tank 3. At the same time, a water inlet 301 is provided on the top of the water tank for timely adding the refrigerant in the water tank when the refrigerant is insufficient. The water tank 3 is usually made of corrosion-resistant and high-temperature-resistant materials to ensure that the water tank will not deform or leak during long-term use. A water inlet and a water outlet are provided in the lower area of the side of the water tank, and the water outlet is used to connect the first pipe 4, and the first pipe 4 is fixedly connected to the water outlet of the circulating water pump 2. The water inlet of the water tank is directly connected to the hollow shell 103 outside the motor body 101 through the second pipe 5. When the circulating water pump 2 extracts the refrigerant in the hollow shell 103 outside the motor body 101, the water inlet of the water tank continues to add refrigerant to the hollow shell 103 outside the motor body 101 through the second pipe 5.
[0026] The circulating water pump 2 is fixedly arranged in the area between the motor body 1 and the water tank 3. The circulating water pump is usually composed of a pump body, an impeller (or rotor), a shaft, a bearing, a sealing device, a driving motor, etc. After the driving motor of the circulating water pump is started, the power is transmitted to the impeller (or rotor) through the shaft, and the impeller (or rotor) starts to rotate, generating centrifugal force, sucking the water at the inlet into the pump body. During the rotation of the impeller (or rotor), its blades will push the water to flow along the channel on the inner wall of the pump body. Due to the action of centrifugal force, the water is thrown to the outlet of the pump body, forming a certain pressure difference. This pressure difference causes the water at the water inlet to be continuously sucked into the pump body.
[0027] Combined with Figure 2 As shown:
[0028] The two ends of the first pipe 4 are respectively connected to the water outlet of the water tank and the water outlet of the circulating water pump 2, and the water inlet of the circulating water pump 2 is fixedly connected to one end of the third pipe 7, and the other end of the third pipe 7 is finally connected to the lower end of the hollow shell 103 outside the motor body 101. The liquid in the hollow shell 103 is pumped back into the water tank 3 through the operation of the circulating water pump 2.
[0029] In order to further optimize the above technical solution, the circulating water pump 2 and the temperature sensing device 7 are monitored and adjusted through a control system. The control system is responsible for receiving input signals and outputting control signals after processing to achieve precise control of the motor operating state.
[0030] Specifically, when the temperature sensing device 7 monitors the temperature of the motor in real time and feeds back the temperature signal to the control system. When the temperature exceeds the preset threshold, the control system will issue an instruction to start the circulation pump. As the coolant circulates, the temperature of the motor body 1 will gradually decrease. When the temperature drops below the preset threshold, the control system will issue an instruction to stop the operation of the circulation pump. In this way, through the cooperation of the temperature sensing device 7 and the circulation pump 2, the precise control and regulation of the motor temperature can be achieved.
[0031] The specific usage is as follows: when the temperature of the coolant in the hollow shell 103 of the motor body 1 is too high, the coolant inside the shell is first extracted, that is, the impeller of the circulating water pump 2 rotates to generate negative pressure, and the coolant in the hollow shell 103 of the motor body 1 is sucked into the pump body and discharged into the water tank 3. When this step is completed, the coolant in the water tank 3 is continuously circulated to the hollow shell 103 of the motor body 1 through the second pipe 5, and the liquid replacement process is completed.
