Problems solved by technology

In the related art, the seat belt pretensioning device has a complex structure and many installation parts. For example, an electric motor is used to drive the seat belt pretensioning, which is costly and cannot effectively control the safety in the scene of sharp turning and rapid acceleration of the vehicle. With locking, the security is poor, and there is room for improvement

Abstract

The invention discloses a safety belt pre-tightening device and a vehicle. The safety belt pre-tightening device comprises a detection mechanism and an execution mechanism, wherein the detection mechanism comprises a detection ball and a shell, the detection ball is movably supported in the shell, the shell is provided with a first electrode layer and a second electrode layer which are spaced in an insulating mode, and the detection mechanism is constructed to enable the detection ball to move in the shell and enable the first electrode layer to be electrically connected with the second electrode layer when the acceleration of the vehicle exceeds a set value; the execution mechanism is electrically connected with the detection mechanism, the detection mechanism outputs an electric signal to the execution mechanism when the first electrode layer is electrically connected with the second electrode layer, and the execution mechanism controls a safety belt to be locked and tightened when receiving the electric signal. According to the safety belt pre-tightening device, the execution mechanism can lock and tighten the safety belt under the working conditions of rapid deceleration or rapid acceleration or sharp turn and the like of the vehicle, and the safety of passengers is guaranteed.

Description

technical field [0001] The present application relates to the technical field of vehicle manufacturing, in particular to a seat belt pretensioner and a Background technique [0002] Car seat belts can effectively protect the safety of drivers and passengers, and avoid or reduce the damage to passengers caused by secondary collisions. In related technologies, the seat belt pretensioning device has a complex structure and many installation parts. For example, an electric motor is used to drive the seat belt pretensioning, and the cost is relatively high, and it cannot effectively control the safety in the scene of sharp turning and rapid acceleration of the vehicle. The belt is locked, the security is poor, and there is room for improvement. Contents of the invention [0003] This application aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the present application is to propose a seat belt pretensioning device, w...
