Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically a push-pull locking mechanism suitable for the confined space of automotive seats. Background Technology

[0002] The flexible adjustment of car seats affects the comfort of drivers and passengers. The movement and locking of the seat rails can adapt to adjust the space for drivers and passengers, thus improving comfort.

[0003] Locking mechanisms should not only be simple and convenient, but also applicable to various scenarios. In order to provide more room for movement for drivers and passengers, the overall seat needs to be optimized. However, the space that can be optimized will inevitably reduce the adjustment space of the seat, so the narrow gap after the car seat is adjusted is particularly important.

[0004] Authorization announcement number: CN 116901796 B discloses a car seat slide rail structure.

[0005] Authorization announcement number: CN110239401 B discloses a crank-rocker type slide rail locking mechanism.

[0006] The two patents mentioned above apply to seats with normal layouts. When the sliding space of the seat is small, the limitation on adjusting the position will not be used. If the size changes, the strength of the slide rail will be sacrificed, and the safety performance cannot be guaranteed. Utility Model Content

[0007] In order to solve the locking problem in the confined space of a car seat without changing the strength of the car slide rail, this utility model provides a push-pull locking mechanism suitable for the confined space of a car seat.

[0008] Therefore, the technical solution of this utility model is a push-pull locking mechanism suitable for the narrow space of a car seat, including an inner rail and an outer rail. The inner rail is set inside the outer rail, and the inner rail protrudes from the outer rail, so that the inner rail moves along the outer rail. The upper part of the inner rail is connected to the car seat frame, and the lower part of the outer rail is connected to the car cabin. The feature is that multiple locking nuts are evenly provided on one side of the inner rail. A fixing plate is provided at the lower part of the outer rail. After the fixing plate extends out of the outer rail, a support part is provided upward. The support part consists of a first support part and a second support part, and the first support part and the second support part are spaced apart. The first support portion and the second support portion are respectively provided with a first through hole and a second through hole; A locking piece is provided through the first through hole and the second through hole. A locking male buckle is provided at the front end of the locking piece, wherein the locking male buckle corresponds to the locking female buckle. The locking plate is also fitted with a spring within the distance between the first support and the second support, and is provided with a spring locking pin; A handle is provided on the fixed plate by means of a rivet, and an unlocking piece is also provided on the handle facing upward; The unlocking piece forms a corresponding movement relationship with the spring lock pin within the distance between the first support and the second support.

[0009] The effect is: The motion relationship in this utility model is as follows: when in use, the handle rotates through the rivet pin, which in turn provides a push-pull force to the spring lock pin through the unlocking plate, causing the locking plate to move back and forth. The rebound force locks and unlocks the locking male and female latches. This utility model is a purely mechanical push-pull motion that can lock and unlock the locking male and female latches, and is suitable for locking and unlocking the inner and outer rails in the confined space of a car seat.

[0010] A further improvement is that the fixing plate and the first and second support parts of the support are integrally stamped structures.

[0011] The advantages are: the one-piece stamping structure is easy to form, the consistency of dimensions can be guaranteed, and it is also suitable for mass production.

[0012] A further improvement is that the handle and the unlocking plate are integrally stamped structures.

[0013] The advantages are: the one-piece stamping structure is easy to form, the consistency of dimensions can be guaranteed, and it is also suitable for mass production.

[0014] A further improvement is that a guide groove is provided on the side of the outer rail corresponding to the locking piece.

[0015] The effect is that the guide groove provides a space for the locking plate to move, making it easier for the locking plate to lock the inner rail and prevent interference.

[0016] A further improvement is that the handle is either "L" shaped, with the outer end of the "L" shaped handle perpendicular to the outer rail and covered with a rubber sleeve.

[0017] The effect is that the "L" shape of the handle extends its control length, further providing power to the spring lock pin.

[0018] A further improvement is that a first retainer and a second retainer are provided inside the outer rail and between the inner rail.

[0019] The effect is that the first and second cages not only allow the inner rail to slide smoothly within the outer rail, but also limit its displacement space, preventing cross-flow and abnormal noise.

[0020] A further improvement is that the first and second retainers include a "W"-shaped structural frame, wherein multiple steel balls are provided on both sides of the "W"-shaped structural frame and a ball bearing is provided in the middle.

[0021] The effect is that the "W" shaped frame structure facilitates the installation of the inner and outer rails, while the steel balls facilitate the movement of the inner rail inside the outer rail. The rolling balls not only facilitate movement but also provide support.

[0022] Beneficial effects: When using this utility model, the handle rotates through the rivet pin, which in turn provides a push-pull force to the spring lock pin via the unlocking plate, causing the locking plate to move back and forth. The rebound force then locks and unlocks the locking male and female latches. This utility model uses a purely mechanical push-pull motion to achieve locking and unlocking of the locking male and female latches, making it suitable for locking and unlocking the inner and outer rails of car seats in confined spaces.
