The invention discloses a safety belt winding device, a safety belt device and a vehicle. The safety belt winding device comprises a frame, a winding shaft and at least one locking seat. The frame comprises a back board and two supporting boards, the back board is connected between the two supporting boards, through holes are formed in the two supporting boards, and at least one through hole is a ratchet wheel hole. The winding shaft is arranged between the two supporting boards in a pivoting manner, two covering discs are arranged on the winding shaft in a spaced manner and arranged adjacent to the corresponding two supporting boards, and an orthographic projection of each covering disc on the corresponding supporting board covers the corresponding through hole. The locking seats are arranged on the corresponding covering discs and provided with brake pawls, and the brake pawls are provided with ratchets suitable for being engaged with the ratchet wheel hole to prevent the winding shaft from rotating in the pull-out direction of a safety belt. According to the safety belt winding device, a dustproof effect and the work reliability are improved, and noise is lowered. In addition, the covering discs can prevent the safety belt from deviating when the safety belt is wound around the winding shaft, and the protective performance of a passenger is improved.
Description
technical field [0001] The invention relates to the field of vehicles, in particular to a safety belt take-up device, a safety belt device and a vehicle. Background technique [0002] In modern society, vehicles have entered thousands of households, and the environments in which vehicles drive are also various. In places with dry climate and severe sandstorms, the dust content in the air is relatively high. Most of the safety belt take-up devices in the vehicle have an emergency locking mechanism, which has the function of detecting the state of the vehicle and taking emergency protection against abnormal driving of the vehicle. The emergency locking mechanism is greatly affected by dust. If the dustproof effect of the emergency locking mechanism is not good, the emergency protection function of the seat belt take-up device will be damaged, and the protection performance of the occupant will be reduced or even invalid. The dustproof performance of the belt device puts forwa...
