The invention discloses an automobile glass guide rail. The automobile glass guide rail comprises an upper guide rail and a lower guide rail. The lower guide rail is provided with U-shaped columns in the length direction, and the U-shaped columns are provided with U-shaped grooves. The upper guide rail is provided with insertion plates matched with the U-shaped grooves, a plurality of insertion blocks are arranged in the length direction of the insertion plates, and insertion holes matched with the insertion blocks are formed in the U-shaped grooves. When the insertion plates are inserted into the U-shaped grooves, the insertion blocks are inserted into the insertion holes. According to the invention, the insertion plates of the upper guide rail are inserted into the U-shaped grooves of the lower guide rail, the insertion blocks of the upper guide rail are inserted into the insertion holes of the lower guide rail, the upper guide rail and the lower guide rail are easily matched, and installation is convenient and fast. Through fastening of the insertion blocks and the insertion holes and matching of the insertion plates and the U-shaped grooves, the upper guide rail and the lower guide rail can be matched more closely, and abnormal sounds caused when automobiles vibrate after installation are avoided.

The invention discloses a method for controlling P-gear parking used for a vehicle. The method comprises the following steps: when a vehicle is on a ramp, obtaining current gradient of the ramp where the vehicle is on; according to the current gradient of the ramp where the vehicle is on, calculating delayable locking time when the vehicle is shifted in a P-gear; in the delayable locking time, controlling an electronic parking brake (EPB) system of the vehicle to operate, and after the EPB system operates, controlling the vehicle to execute P-gear locking operation. The method for controlling P-gear parking can reduce acting force between a P-gear lock cylinder and a P-gear lock slot when a vehicle parks on a ramp, so as to prevent abnormal sound caused by P-gear unlocking when the vehicle parks on the ramp. The invention also discloses a system for controlling P-gear parking used for a vehicle, and the vehicle with the P-gear parking control system.

The invention discloses a door check, and relates to the technical field of automobile parts. The door check comprises a limiting support, a limiting pull plate and a limiting assembly, wherein the limiting assembly is fixedly connected to a vehicle door, one end of the limiting support is connected to a vehicle body, the other end of the limiting pull plate penetrates through the limiting assembly and then extends into the space inside the vehicle door, the limiting assembly is used for limiting the limiting pull plate, and the opening-closing angle of the vehicle door is fixed. According to the door check, the movement noise of the limiting pull plate can be eliminated when the vehicle door is opened and closed, the influence of rainwater corrosion and the influence of bad effects caused by internal abrasion of the door check are avoided, and the service life of a door check assembly is prolonged.

The invention discloses a shock-absorbing pedal of a motorcycle. In the shock-absorbing pedal, a rear connecting tube consists of an upper connecting tube and a lower connecting tube, wherein, the rear part of the lower connecting tube turns up to form an inclined section, and the lower end of the upper connecting tube is sheathed into the inclined section; a first spring is arranged in the inclined section of the lower connecting tube, the lower end of the first spring is abutted with a first locating plate fixed in the inclined section, and the upper end of the first spring is abutted with a second locating plate on the bottom end of the upper connecting tube; and a second spring is sheathed on the upper connecting tube, the lower end of the second spring is abutted with the second locating plate, and the upper end of the second spring is abutted with an inner flange at an upper port of the inclined section of the lower connecting tube. In the invention, shock of the foot pedal is lowered during the running process of the motorcycle by virtue of elasticity of the springs, which effectively improves riding comfortability; and the shock-absorbing pedal has the characteristics of artful design, simple structure, easy reconstruction, low reconstruction cost and the like, and can be widely applied to various two-wheeled motorcycles.
