The utility model relates to a remote controller with a safety battery compartment, the remote controller comprises a shell and a battery cover, a storage compartment is arranged on the surface of the shell, and the battery cover is rotatably matched with the storage compartment; a limiting part is arranged in the storage cabin, the battery cover is provided with a clamping part, and the limiting part is matched with the clamping part to limit the battery cover to rotate and be separated relative to the storage cabin. Through an interlocking mechanism of the limiting part and the clamping part, including the matching of the L-shaped first limiting piece and the first clamping piece and the matching of the second limiting piece and the second clamping piece, the vertical separation of the battery cover and the storage cabin is prevented through the first limiting piece, and the constraint is relieved through the elastic deformation of the second limiting piece; when the battery cover is opened, the second limiting piece needs to be poked by external force while the battery cover is rotated, the operation complexity far exceeds the cognitive ability of children, and the risk of mistakenly swallowing the battery is effectively avoided.

This application discloses a cooling assembly for an electric motor, an electric motor, and a vehicle. The cooling assembly includes an inlet and an outlet arranged within a sealed cavity. Both the inlet and outlet are provided with cooling fluid inlets, forming a circulating flow channel within the motor and the sealed cavity. The middle section of the circulating flow channel is a disc-shaped cooling space, in which the cooling fluid directly contacts the winding unit. One of the orientations of the disc surface and the disc wall of the cooling space is the cooling fluid inflow direction, and the other is the cooling fluid outflow direction. In this application, the cooling fluid in the cooling space can form a diffuse inflow field surrounding the winding unit through the directional distribution of the inlet, ensuring sufficient contact between the cooling fluid and the winding unit. After heat exchange, the cooling fluid is led out by the outlet. The cooling fluid enters from the axial or circumferential end face of the cooling space and exits from the circumferential or axial end face, allowing the cooling space to cover the entire area of ​​the disc-shaped cooling space, significantly improving the heat dissipation effect.

The invention discloses a cooling assembly of a motor, the motor and a vehicle, the cooling assembly comprises an inflow piece and an outflow piece which are arranged in a sealing cavity in the axial direction, the inflow piece and the outflow piece define a cooling space, and the inflow piece and the outflow piece are each provided with a cooling fluid flowing opening. The winding unit comprises a cooling space and an outflow part, the outflow part is arranged in the cooling space so that cooling fluid can be injected into and led out of the cooling space, at least part of the winding unit penetrates through the inflow part to stretch into the cooling space and makes direct contact with the cooling fluid in the cooling space, and the extension length of the outflow part in the axial direction is larger than the extension length of the inflow part in the axial direction. Cooling fluid can form a cooling fluid flow field wrapping the periphery of the winding unit through directional flow distribution of the flow inlet piece, the cooling fluid is led out through the flow outlet piece after heat exchange is completed, the heat dissipation effect is guaranteed, the axial extension length of the flow inlet piece is smaller than that of the flow outlet piece, the heat exchange area can be increased, the flow speed of the cooling fluid in the iron core gap can be increased, and the heat dissipation effect is enhanced.
