Description

Technical Field

[0001] The present application relates to the field of automobile seat slide rails, and in particular to a locking mechanism for a slide rail on an automobile seat. Background Art

[0002] Car seats can usually be adjusted and slid forward and backward. Their main structure includes an upper slide rail and a lower slide rail. While the upper and lower slide rails slide with each other, they also need to be locked by a corresponding locking structure to keep the relative sliding of the two in a relatively static state when no adjustment is needed.

[0003] The conventional locking mechanism is generally installed on the upper slide rail. The locking mechanism includes a lock tongue with locking teeth, which is locked by cooperating with the lock tongue and the locking groove on the lower slide rail. The locking mechanism includes a locking box for installing the lock tongue and other related parts. Locking openings are respectively provided on both sides of the locking box. The traditional locking box installation is to install the locking box on the upper slide rail by cooperating with the upper locking box and the lower locking box. During assembly, the upper locking box is inserted into the locking opening, and the lower locking box is installed into the lower end of the upper locking box from below. The locking opening is provided on the side wall of the upper locking box, and the lower locking box is provided with elastic locking teeth that can be inserted into the locking opening.

[0004] However, the inventor believes that although the cooperation of the upper and lower locking boxes can play a locking function, since the elastic locking teeth of the lower locking box itself have an elastic function, after the seat is subjected to a shaking external force, the upper and lower locking boxes will also be affected by the external force, which can easily cause the elastic locking teeth themselves to deform, resulting in the risk of the elastic locking teeth detaching from the locking holes. In addition, this structure also has the problem that when a car seat equipped with such a structure is being transported, since there is no locking relationship between the upper locking box and the upper slide rail, if the car seat is placed upside down, during transportation shaking, the entire upper and lower locking boxes will directly detach from the locking mouth toward the upper slide rail; in addition, when a seat equipped with such a structure is in use, the upper and lower contractions may detach from each other, resulting in the failure of the seat's forward and backward sliding adjustment function, which poses a lot of insecurity during vehicle driving. Utility Model Content
