Description

Worm wheel with self-locking structure for automobile seat level regulator Technical Field The utility model belongs to the technical field of automobile seat adjustment, and particularly relates to a worm wheel with a self-locking structure for an automobile seat horizontal adjuster. Background In an automobile seat adjusting system, a seat level adjuster is a key component for adjusting the front and rear positions of a seat, the existing seat level adjuster adopts a worm gear transmission structure to realize the horizontal movement of the seat, however, the traditional worm gear transmission lacks a reliable self-locking function after the seat is adjusted in place, and the seat can be displaced due to conditions of road surface jolt, rapid acceleration or rapid braking and the like in the running process of an automobile, so that the comfort of drivers and passengers is influenced, and certain potential safety hazards exist. Therefore, a worm wheel with a self-locking structure for a horizontal regulator of a car seat is proposed in view of the above-mentioned problems. Disclosure of utility model In order to solve the problems in the prior art, the utility model provides the worm wheel with the self-locking structure for the automobile seat level regulator, which can realize reliable self-locking after the seat is regulated in place, prevent the seat from displacing in the automobile driving process and improve the comfort and safety of drivers and passengers. The technical scheme is that the worm wheel with the self-locking structure for the automobile seat horizontal regulator comprises a shell with an opening at the top end, a top cover matched with the opening is arranged at the top end of the shell, a worm is rotatably connected inside the shell, the surface of the worm is in meshed connection with the worm wheel, the worm wheel is rotatably connected inside the shell, and a locking assembly is arranged inside the top cover; The locking assembly comprises a rotating rod arranged between the top cover and the shell, the top end of the rotating rod penetrates through the surface of the top cover and extends to the upper side of the top cover, a connecting column is fixedly connected to the bottom end of the rotating rod, a connecting groove matched with the connecting column is formed in the surface of the worm, a first locking piece is fixedly connected to the side face of the rotating rod, a second locking piece matched with the first locking piece is fixedly arranged in the top cover, a fixing disc is fixedly connected to the top end of the worm, a spring is fixedly connected between the first locking piece and the fixing disc, and the spring is in a compressed state.
