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 embodiment of the present invention discloses a front wheel pressure regulation method, device and storage medium. The front wheel pressure regulation method comprises: obtaining a brake pedal stroke signal; determining the front wheel pressure state according to the brake pedal stroke signal; adjusting the opening of the front wheel inlet valve or maintaining the opening of the front wheel inlet valve according to the front wheel pressure state to control the front wheel boost rate. This solution can reduce the boost rate of the front wheel by adjusting the opening of the front wheel inlet valve, prevent the front wheel pressure from reaching the locking critical point quickly, and prevent the front wheel from entering the locking state quickly, thereby reducing the braking distance and enhancing the safety of vehicle braking to a certain extent. In addition, by adjusting the opening of the front wheel inlet valve to reduce the front wheel boost rate, the vehicle's powertrain suspension can be prevented from hitting the limit, avoiding collision noise and collision vibration inside the vehicle, and ensuring the comfort of the vehicle to a certain extent.

This utility model provides a bathroom cabinet drawer buffer slide structure, belonging to the technical field of furniture hardware accessories. It includes a cabinet frame and a drawer body, which are detachably connected. An outer rail assembly is provided on the inner side of the cabinet frame, and an inner rail assembly is provided on the outer side of the drawer body. Through the outer rail assembly, this utility model enables a retractable damper and spring-assisted slider to move with the inner rail. When the drawer body is pushed in to its final stroke, the damper is triggered, the piston is compressed, and internal oil flows slowly through small channels, creating resistance and gradually reducing the drawer body's speed to a standstill. The inner rail assembly enables a meshing plastic rack and pinion to effectively improve the stability of the inner rail and drawer body during movement. Therefore, this structure provides a buffer function when the drawer body is pulled out or pushed in, and avoids collision noise when closing.
