Problems solved by technology

[0005] The scheme of the above-mentioned patent document is mainly to reduce the noise generated at the balance wheel structure, and the friction force generated by the swing method is unstable. The technical solution that produces friction cannot be realized
[0006] To sum up, there is an urgent need for a retractor that can reduce noise at the position of the vehicle sensor component and can generate friction stably, but there is no report about this retractor

Abstract

The invention relates to an emergency locking retractor for noise reduction on a vehicle sensing assembly. The emergency locking retractor comprises a belt sensing assembly, a noise reduction piece and the vehicle sensing assembly; the belt sensing assembly is provided with a disc outer tooth, the noise reduction piece is arranged on the disc outer tooth, the interaction force exists and the extrusion is generated between the noise reduction piece and the disc outer tooth, and the disc outer tooth performs circular motion under the trigger of a ribbon and provides a movement trend for the noise reduction piece to generate friction force; when the ribbon is unreeled, the noise reduction piece rotates and squeezes a vehicle sensing arm of the vehicle sensing assembly from the front face or side face through a locking mechanism of the noise reduction piece, thereby limiting moving space of a steel ball of the vehicle sensing assembly; when the ribbon is pulled out, the noise reduction piece rotates reversely, and the noise reduction piece breaks away from the vehicle sensing arm of the vehicle sensing assembly. The emergency locking retractor for the noise reduction at the vehicle sensing assembly has the advantages that the steel ball state of the vehicle sensing assembly can be limited, so that after a passenger does not wear or wears a safety belt, the steel ball is in a specified position and cannot move due to vehicle running, thereby eliminating the sound made by the vehicle sensing assembly.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a retractor for reducing noise at the position of a car sensing component. Background technique [0002] With the rapid development of the automobile industry, automobiles have become a product with a high penetration rate and have entered thousands of households. Therefore, people's requirements for the safety and comfort of automobiles are also constantly improving. The retractor is a key component of the passive safety of the car. [0003] The retractor refers to the retractor with emergency locking function, which is the core component of the car seat belt. Car seat seat belt retractor, the traditional seat belt is installed behind the car body, the steel ball in the car sensor component is in a relatively free state, affected by the operation of the vehicle, it collides with nearby parts and makes a sound, this kind of interference sound is easy to make the user produce...
