Description

TECHNICAL FIELD

[0001] The present application relates to the field of power machinery, in particular to a motor. BACKGROUND

[0002] A wire box needs to be installed on each motor to facilitate wiring during subsequent motor use. The existing circuit cover on the wire box is generally stamped from an aluminum plate. In order to ensure the sealing performance of the circuit cover and the circuit integrated end cover, the circuit cover needs to have a certain thickness, otherwise the circuit cover is prone to bending and deformation. The circuit cover and the circuit integrated end cover are connected by screws. Specifically, an outwardly protruding mounting portion is formed at the edge of the circuit cover and the circuit integrated end cover. The mounting portion on the circuit cover has a through hole, and the mounting portion on the circuit integrated end cover has a threaded hole. The screw is connected by passing through the through hole and the threaded hole. Considering the overall volume of the motor, in order to reduce the size of the mounting portion, the screw is generally small in size. Therefore, if the circuit cover is relatively thin, the portion between the two screws in the circumferential direction of the circuit cover is prone to deformation, resulting in poor sealing performance.

[0012] By adopting the technical scheme, when the circuit cover is assembled to the circuit integrated end cover, the mounting portion of the circuit cover does not interfere with the circuit integrated end cover.

[0013] In a possible implementation, an annular protrusion is formed on the end face of the circuit integrated end cover away from the motor body, and the side edge of the circuit cover abuts against the inner circle of the annular protrusion.

[0014] By adopting the technical scheme, the annular protrusion is arranged mainly to facilitate the installation of the circuit cover, and the outer diameter of the circuit cover can be understood as the same as the inner diameter of the annular protrusion, or gap fit (such gap fit is formed due to machining precision).
