Description

Automobile and automobile side sliding door Technical Field The invention relates to the technical field of reduction boxes, in particular to an automobile and an automobile side sliding door. Background The reduction gearbox is called as a speed reducer or a speed reducer, and is mainly used for reducing the output of a motor or improving the output of the motor, and works according to the principle that a prime mover is connected with the reduction gearbox and then connected with a working machine, and is power transmission equipment, and can be classified into a worm gear reduction gearbox, a worm gear reduction gearbox, a planetary reduction gearbox and the like. The automatic side sliding door of the automobile is connected with the power mechanism thereof through a reduction gearbox, so that the proper moving speed of the automatic side sliding door and enough output torque are ensured. At present, a worm gear gearbox is generally adopted in a braking device of an automatic side sliding door, a worm in the gearbox and a spur gear are generally arranged vertically, the arrangement can lead to the situation that the inclined teeth of the worm and the teeth of the spur gear can generate larger noise and lose partial power in the meshing process, the use experience of a customer is affected, and a braking mechanism is lacking, so that the braking force of the side sliding door is insufficient when an automobile parks on a slope, and the automobile door is automatically opened or closed. Disclosure of Invention The invention aims to provide an automobile, an automobile side sliding door and an inclined reduction gearbox thereof, which enable meshing of a worm and a main gear to be smoother, reduce collision between the main gear and the worm, reduce noise of the reduction gearbox, improve customer experience, enable power to be sufficient when the automobile side sliding door is opened and closed, enable braking force to be sufficient in a slope parking process, and prevent automatic opening or closing of a vehicle door in the slope parking process.
