Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric machines, and more particularly, to a high-efficiency heat-dissipation moisture-proof electric machine. BACKGROUND

[0002] As a core power device in the development process of modern industry and technology, electric machines play an irreplaceable role in many fields such as automobiles and transmission machinery, and promote the continuous progress of various industries.

[0003] However, the specific requirements of electric machines are different in different use scenarios, and electric machines may be used in different environments, for example, in the field of electric vehicles, electric machines are used in different temperature environments. And in different regions, different weather, the humidity requirements of the environment are different. Although the existing electric machines have some basic protection measures, such as simple shell sealing, these measures are often difficult to resist the invasion of long time and high humidity. Electric machines will generate a lot of heat during operation, which will cause the temperature of the electric machine to rise if it cannot be dissipated in time and effectively, affecting the performance and service life of the electric machine. The existing electric machine cooling methods mainly rely on traditional means such as heat sinks and fans, but in some high-load, long-time running scenarios, these cooling methods often appear to be ineffective. Since the demand for heat dissipation and moisture-proof of electric machines changes during use, and may need to be switched during the operation of the electric machine, the existing electric machines cannot meet this function.

The outer diameter of the annular convex plate 4.4 is less than or equal to the inner diameter of the outer circular cylindrical plate 5.4, and the difference between them is less than 1 mm.

[0070] Working principle: the motor of the application, under the driving of the driving motor, the movable cover can translate along the direction of the rotating shaft, so that the movable cover can switch between the first state, the second state and the third state. Therefore, according to the measurement value of the temperature sensor (or according to the temperature signal obtained by the system where the motor of the application is located), the movable cover can be controlled to switch between the first state, the second state and the third state. When the temperature is low, the movable cover is in the first state, so that each first strip-shaped through hole is shielded by the inner annular plate, so that it has good moisture-proof effect. When the temperature is slightly high, the movable cover is in the second state, at this time, the end plate and the inner annular plate have a spacing, but along the direction of the rotating shaft, the first strip-shaped through hole is still shielded by the inner annular plate, so that the first strip-shaped through hole is still shielded to a certain extent while the natural heat dissipation can be achieved, thereby also playing a certain protection effect. When the temperature rises again, the movable cover is in the third state, at this time, the first strip-shaped through hole is aligned with the second strip-shaped through hole, and at this time, the passive abutting plate abuts against the driving abutting plate, so that the passive abutting plate is driven to rotate synchronously with the rotating shaft by the abutting of the driving abutting plate, so that the rotating blade generates a heat dissipation airflow, thereby achieving good heat dissipation effect.

[0071] Under the action of the tension spring, in the first state, the inner annular plate stably abuts against the end plate. In the second state, the first abutting plane can abut against the end plate, so that it can stably be in the second state under the action of the tension spring and the first abutting plane. In the third state, the second abutting plane can abut against the end plate, so that it can stably be in the third state under the action of the tension spring and the second abutting plane. And under the action of the laser emitter and the light receiver, when the two movable covers are independently driven, they can be synchronously rotated, and the two movable covers remain in the synchronous rotation state, which indicates that the driving of the two movable covers is in normal state and neither of them is abnormal. And the circular ring-shaped convex plate and the outer circular ring-shaped cylindrical plate can shield the space where the tension spring is located, avoiding the entry of sundries thereinto. The second annular mounting plate and the third annular mounting plate can shield the space where the driving abutting plate is located to a certain extent, avoiding the entry of sundries thereinto. Therefore, the movable cover can be better driven and is not prone to failure.

[0072] Although the application is illustrated and described in terms of preferred embodiments, it will be understood by those skilled in the art that various changes and modifications can be made without departing from the scope of the application as defined by the claims.
