Problems solved by technology

[0002] The demand for electric vehicle motors in the market is increasing, and the performance requirements are also getting higher and higher. However, when the current electric vehicle motors are assembled, the connecting plate and end cover are directly installed with the barrel of the motor, and the sealing effect is not good. , there is a problem of poor waterproofing during use. Once the motor enters water, it is easy to burn out the motor and affect the normal driving of the electric vehicle

Abstract

The invention relates to a motor with good sealing performance. The motor comprises a motor body, a middle connecting plate and an end cover, wherein the middle connecting plate and the end cover areeach provided with a spigot to be connected with a machine barrel of the motor body, a groove is formed in the outer side of the root part of the spigot of each of the middle connecting plate and theend cover, and the grooves are used for mounting O-shaped rings; and barrel ports of the machine barrel are clamped on the outside of the O-shaped rings after the end cover and the middle connecting plate are mounted with the machine barrel, thereby achieving a sealing effect. The middle connecting plate and the end cover of the motor are optimized on the premise of maintaining the original motor,the grooves for placing the O-shaped rings are formed in the spigots connected with the machine barrel, the O-shaped rings are used for static sealing, and the overall waterproof performance of the motor can be effectively improved; and the O-shaped rings are cheap, simple to manufacture, reliable in function, simple in mounting requirements and convenient to replace.

Description

technical field [0001] The invention relates to the field of electric vehicle motors, and specifically discloses a motor with good sealing performance. Background technique [0002] The demand for electric vehicle motors in the market is increasing, and the performance requirements are also getting higher and higher. However, when the current electric vehicle motors are assembled, the connecting plate and end cover are directly installed with the barrel of the motor, and the sealing effect is not good. , There is a problem of poor waterproofing during use. Once the motor enters water, it is easy to burn out the motor and affect the normal driving of the electric vehicle. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a motor with good sealing performance, which increases the waterproof performance of the electric vehicle motor. [0004] The technical solution adopted in the present invention is: a motor wi...
