Car seat sliding rail unlocking mechanism

Abstract

Provided is a car seat sliding rail unlocking mechanism. The unlocking mechanism comprises a wrench, a fixed bracket, a torsion spring, a fixed shaft and an unlocking handle. A wrench hole is formed in the one end of the wrench and an abdication hole is installed near the middle part of the wrench; a shaft hole and a pin hole are installed between the other end of the wrench and the abdication hole; the one side of the abdication hole is provided with a limited hook; the upper end and the lower end of the wrench are provided with a first fold and a second fold; a first torsion spring hole is formed in the first fold. The one side of the fixed bracket is provided with a fold; a fixed hole, and a second torsion spring hole and a limited groove are formed in the fold; the limited groove is fitted with the limited hook; the wrench is installed on the fixed bracket in a rotating mode through the fixed shaft. The torsion spring is installed on the fixed shaft in a clamping mode, wherein a first torsion spring hook and a second torsion spring hook are installed on the torsion spring. A connector is installed on the both sides of the middle handle of the unlocking handle; the connector is in a sheet shape, and the middle of the connector is provided with a connecting hole; the connecting hole is corresponding to the pin hole; the connecting hole and the pin hole are connected through a pin so that the unlocking handle is fixed on the wrench. The car seat sliding rail unlocking mechanism has the advantages that the unlocking is reliable; the synchronization is good; there is no abnormal sound; the misoperation force of the sliding rail is guaranteed when the sliding rail is unlocked and the manufacture is convenient.

Description

technical field [0001] The invention belongs to the technical field of vehicle accessories, and in particular relates to an unlocking mechanism for a sliding rail of an automobile seat. Background technique [0002] The car seat slide usually includes a moving guide, a fixed guide, a locking mechanism and an unlocking mechanism. Its function is to change the front and rear positions of the seat and lock the seat. Chair rails are mandatory. In this regard, a detailed understanding can be obtained from previously disclosed Chinese patent documents, such as the Chinese utility model patent authorization announcement number CN204354858U, which discloses a "car seat slide rail assembly", It describes two kinds of unlocking mechanisms, and its contribution lies in that it is simpler in structure than previous unlocking mechanisms. However, in the actual use process, the following problems are also exposed: the unlocking mechanism in the shape of "a few" needs to be fixed by weld...

AI Technical Summary

Problems solved by technology

However, in the actual use process, the following problems are also exposed: the unlocking mechanism in the shape of "a few" needs to be fixed by welding, the processing accuracy is high, the consistency is difficult to control, the unlocking synchronization is poor, and the installation is difficult. At the same time, the unlocking mechanism The center of rotation is placed outside the sliding guide rail, which takes up a lot of space and has a small scope of application; the "U"-shaped unlocking mechanism adopts a steel wire structure with poor stability, and the synchronization of unlocking on both sides is poor, and the connection between the unlocking mechanism and the locking mechanism There is a period of empty travel, and there will be abnormal noise due to the contact between metal parts when unlocking

Moreover, the unlocking mechanism in the prior art has no limit structure, so that the misoperation force (also known as overload loading force) of the slide rail when unlocking can only be guaranteed by the locking mechanism, which cannot meet the actual needs of users.
