The positioning tool for the sealing pressing strip of the passenger room door is convenient and fast to operate, and the first extrusion piece and the second extrusion piece cannot influence each other.

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.

According to the technical scheme, the automobile back row lock catch is characterized in that the automobile back row lock catch comprises a metal base, the metal base comprises a bottom plate, a first vertical plate and a second vertical plate, the first vertical plate and the second vertical plate are fixed to the two sides of the bottom plate, a pull belt is fixed to the first vertical plate, and a first lock catch is fixed to the pull belt; a second lock catch rotating vertically is hinged to the second vertical plate, a rotating shaft is arranged between the second vertical plate and the second lock catch and sleeved with a torsional spring driving the second cable harness to rotate upwards, the first lock catch is connected with a first bunch, the second lock catch is connected with a second bunch, the first bunch and the second bunch are fixed together, one of the two adjacent lock catches is rotationally connected, and the other lock catch is rotationally connected with the other lock catch. One lock catch is connected with the other lock catch through a drawstring, so that only one lock catch can swing, the other lock catch is positioned, the situation that the two lock catches collide with the hip of a sitting user at the same time is avoided, and the comfort of the sitting user is improved when the sitting user sits in the back row.

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.
