The utility model provides a glass guide rail installation structure, a vehicle door and a vehicle. The glass guide rail installation structure comprises a lower support located in the vehicle door. The lower support is located at the bottom end of the glass guide rail, is in an n shape and is provided with an installation platform located in the middle and installation supporting legs arranged on the two opposite sides of the installation platform respectively. The lower support is fixedly connected into the vehicle door through the installation supporting legs on the two sides, and the bottom end of the glass guide rail is fixed to the installation platform. According to the glass guide rail installation structure, the lower support is arranged to be in the shape of the Chinese character'ji ', the supporting legs on the two sides are connected with the automobile door, the rigidity of the lower support of the glass guide rail and the connecting rigidity between the lower support and the automobile door metal plate can be improved, and the abnormal sound problem that automobile door glass shakes due to insufficient rigidity of installation points of the glass guide rail is avoided. And a good use effect is achieved.

The utility model provides a vehicle body stand column and a vehicle, the vehicle body stand column comprises a stand column outer plate, a stand column inner plate and a stand column reinforcing plate clamped between the stand column outer plate and the stand column inner plate, the stand column reinforcing plate comprises a plurality of branch reinforcing plates, and the branch reinforcing plates are sequentially arranged in the height direction of the vehicle. The adjacent portions of the adjacent branch reinforcing plates are provided with overlapping areas, the overlapping areas are connected through connecting pieces, and receding holes are formed in the stand column inner plate and used for allowing installation tools for installing the connecting pieces to penetrate through. According to the automobile body stand column, the overlapping areas are arranged on the adjacent portions of the adjacent branch reinforcing plates and connected through the connecting pieces, the receding holes are formed in the stand column inner plate, and the stand column inner plate, the stand column outer plate and the reinforcing plates are still welded in a three-layer mode. The reinforcing structures of the column inner plate and the column outer plate can be continuous in the height direction of the vehicle, so that the overall structural strength of the vehicle body column can be well enhanced, and the collision resistance of the vehicle can be improved.

The utility model discloses an automobile brake which comprises a support, a caliper body is installed on the support, a nut is arranged in the caliper body, the inner side of the nut is in threaded connection with a lead screw, one end of the lead screw is provided with a piston, and the other end of the lead screw is sequentially sleeved with a support, a plane thrust bearing assembly, a pressure sensor and a lining. An elastic mechanism is arranged at the end, away from the piston, of the lead screw. The caliper body is provided with two friction plates used for braking, and one friction plate abuts against the piston. The elastic mechanism is additionally arranged at the end of the lead screw, in the lead screw transmission process, the structure not only eliminates the axial clearance of the lead screw, but also reduces friction of the lead screw during working rotation, improves the working efficiency of a product, avoids shaking and vibration abnormal sound caused by too large clearance of connecting pieces, and also avoids impact and abnormal sound caused by stress in the braking process, so that the service life of the product is prolonged, and the service life of the product is prolonged. And the service life of the part is influenced.
