电机壳体和电机

Abstract

本申请提供一种电机壳体和电机，涉及电机技术领域。该电机壳体包括壳体本体、第一盖板和第二盖板，壳体本体上设有第一安装槽和第二安装槽；第一盖板覆盖第一安装槽，并用于与电机控制器电连接，第一盖板被配置为，第一盖板与壳体本体分离时，断开电机控制器和电机的电连接，第二盖板覆盖第二安装槽；第一盖板上设有至少一个限位部，限位部与第二盖板连接，限位部被配置为，在第一盖板连接在壳体本体上时，限制第二盖板由壳体本体上拆卸。本申请的电机壳体，通过第一盖板与壳体本体分离时，断开电机控制器和电机的电连接，并通过限位部，使得第二盖板仅在第一盖板拆卸后才能被拆卸，确保第二盖板拆卸后的电机处于断电状态，利于提高操作安全性。

4. The motor housing of claim 3, wherein, The limiting part (210) bends toward the first part (121), and the second cover plate (300) is provided with a connecting arm (311) that bends toward the first part (121), and the limiting fitting part (3111) is provided on the connecting arm (311).

5. The motor housing of claim 4, wherein, The limiting part (210) and the limiting mating part (3111) are inserted together; Alternatively, the limiting mating part (3111) has a first inclined surface that is inclined toward the limiting part (210), and the limiting part (210) has a second inclined surface (212) that is inclined toward the limiting mating part (3111), and the second inclined surface (212) abuts against the first inclined surface.

6. The motor housing of claim 5, wherein, One of the limiting part (210) and the limiting mating part (3111) is a insert and the other is a socket, and the insert and the socket are inserted into each other; Alternatively, one of the limiting part (210) and the limiting mating part (3111) may be a protrusion and the other may be a groove, with the protrusion and the groove being inserted into each other.

7. The motor housing of any one of claims 1 to 6, wherein, It also includes at least one connector (800), the limiting part (210) bends toward the second cover plate (300) and abuts against the side of the second cover plate (300) away from the housing body (100), the connector (800) passes through the limiting part (210) and the second cover plate (300) and is connected to the housing body (100).

8. The motor housing of any one of claims 1 to 6, wherein, It also includes a switching component (600); The on / off component (600) is disposed between the first cover plate (200) and the electrical connector (400). The on / off component (600) is configured to send a power supply signal to the motor controller when the first cover plate (200) is connected to the housing body (100); and to disconnect the power supply signal when the first cover plate (200) is separated from the housing body (100).

9. The motor housing of claim 8, wherein, The on / off assembly (600) includes a trigger (610) and a triggered component (620).
