Description

Technical Field

[0001] The present invention relates to the technical field of motors, and more specifically, to an efficient heat dissipation motor and its motor end cover. Background Art

[0002] Motors play a crucial role in fields such as electric vehicles and mechanical transmissions, and are indispensable kinetic energy output devices in these systems. With the continuous progress and innovation of technology, the application prospects of motors will be broader, providing strong support for the development and progress of related industries.

[0003] The existing heat dissipation mode of motors is single, but the requirements for heat dissipation and dust prevention of motors are different in different situations. The existing usage mode of motors is single and cannot meet the usage in different environments. For example, the environments of cars for urban commuting and high-intensity off-road vehicles are quite different. Although both are equipped with motors as power sources, their working environments are very different. Cars for urban commuting usually drive on urban roads, and the environment is relatively mild. High-intensity off-road vehicles, on the other hand, need to drive in complex and changeable outdoor environments, and have more complex heat dissipation requirements. In addition, the working conditions in factories and those for outdoor use also have different requirements for the use of motors. The environment in factories is usually relatively enclosed with high cleanliness, while motors used outdoors have a low environmental cleanliness and face more complex heat dissipation requirements. Therefore, the existing motors cannot meet the usage requirements in different environments. Summary of the Invention

The heat conduction blocks 5.2 and the heat dissipation through holes 4.1 are both radially distributed.

[0115] Working principle: The motor of the present application can be used in different states, and different combinations of modules are used in different modes. When the requirements for heat dissipation and dust prevention are relatively low, the first state can be used, and natural heat dissipation is achieved through the heat dissipation through holes at this time. When used in an environment with high dust prevention requirements, the second state can be used. Although the heat dissipation through holes are blocked at this time, due to the multiple heat dissipation fins on the front and back of the heat conduction block, a good heat dissipation effect can also be obtained. When dust prevention is required and higher heat dissipation requirements are needed, an air cooling module can be installed, so that the rotating blade can suck air from the air inlet hole and discharge air from the air outlet hole, thereby realizing the purging of the heat dissipation fins and achieving a better heat dissipation effect. When the requirements for heat dissipation are further increased, a liquid cooling module can be installed, so that during the circulation of the heat conduction liquid, the heat dissipation fins are wrapped by the circulating heat conduction liquid, thereby achieving a better heat dissipation effect.

[0116] And at this time, although the rotating blade cannot be used for heat dissipation, it can generate a detection air flow, so that the air flow can enter from the air inlet hole, exit from the air outlet hole, and finally exit from the air outlet groove. Thus, the air flow at the air outlet groove can be detected by the wind speed sensor. And through the detection of the wind speed sensors at the two air outlet grooves, comparing the differences in the measured values of the two, as well as the differences in the measured values at different times of itself, it is possible to detect whether the installation of each module is loose. When looseness occurs, due to the generation of a gap (or a local gap) between the inner circular ring part and the inner circular ring gasket, air leakage will occur, which will lead to abnormal measured values of the wind speed sensor. Therefore, an alarm can be given in time when looseness occurs.
