[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 This utility model provides a technical solution: a car seat slide rail locking mechanism, which is set on a public rail 5. The locking mechanism includes a locking plate 1, a locking box 2, a locking shaft 3 and a spring 4. The locking box 2 is connected to the public rail 5.

[0020] The locking plate 1 and the locking shaft 3A' are fixedly connected. Specifically, the locking plate 1 and the locking shaft 3 are fixedly connected by a fixed riveting. In order to prevent the locking plate 1 from rotating after riveting during installation, the outer wall of the locking shaft 3 is provided with a positioning key 31. The locking plate 1 is provided with a mounting hole 11 that matches the shape of the outer wall of the locking shaft 3. Specifically, in this embodiment, the cross-section of the locking shaft 3 is elliptical. The locking shaft 3 is provided with a mounting step 32, which is fixedly set on the outer wall of the locking shaft 3. The diameter of the mounting step 32 is larger than the diameter of the mounting hole 11, so as to prevent the locking shaft 3 from moving axially in the A direction and to quickly determine the arrival of the locking shaft 3 at the mounting point during installation.

[0021] The locking box 2 and spring 4 are movably sleeved on the outer wall of the locking shaft 3, with spring 4 positioned between the locking box 2 and the locking plate 1. The A' end of spring 4 is connected to the locking shaft 3. Specifically, a fixed step 33 is fixedly provided on the outer wall of the locking shaft 3. The diameter of the A' end of spring 4 is smaller than the diameter of the fixed step 33. The A' end of spring 4 abuts against the A' end of the fixed step 33, thereby restricting the movement of the A end of spring 4 and ensuring that spring 4 applies a preload force towards the A direction to the locking shaft 3. A protrusion 41 is fixedly provided at the A end of spring 4, protruding outwards. The locking box 2 has a connecting slot through which the protrusion 41 passes. The connecting slot restricts the rotation of the protrusion 41. To balance the overall movement of spring 4, two protrusions 41 are provided and arranged opposite each other. The number and position of the protrusions 41 correspond to the number and position of the connecting slots.

[0022] The public rail 5 is provided with a connecting hole 51. The locking box 2 passes through the connecting hole 51. The locking box 2 includes a box body 21, a connecting U-shaped piece 22, and a connecting boss 23. The connecting U-shaped piece 22 and the box body 21 are fixedly connected, and the two connecting U-shaped pieces 22 are located on opposite sides of the box body 21. The connecting boss 23 is located on the side of the connecting U-shaped piece 22 away from the box body 21. When the locking box 2 is connected to the public rail 5, the box body 21 abuts against the A surface of the public rail 5, and the connecting boss 23 abuts against the A' surface of the public rail 5. Since the connecting U-shaped piece 22 has a certain deformation, when the locking box 2 passes through the connecting hole 51 from A to A', the connecting U-shaped piece 22 can deform towards the box body 21, so that the connecting boss 23 passes through the connecting hole 51.

[0023] The locking shaft 3 passes through the locking box 2, which has a limiting hole 24 that matches the shape of the outer wall of the locking shaft 3. The protrusion 41 of the spring 4 passes through the connecting groove and abuts against the surface of the guide rail 5A to prevent the spring 4 from moving.

[0024] Assembly process of this utility model:

[0025] S1. Spring 4 is assembled onto locking shaft 3, and locking shaft 3 is assembled onto locking plate 1;

[0026] S2. The locking shaft 3 is fixedly riveted to the locking plate 1. There is a gap between the spring 4 and the locking plate 1. The spring 4 can rotate around the axis of the locking shaft 3.

[0027] S3. Assemble the pre-assembled parts that have completed S2 onto the public rail 5. At this time, the spring 4 is in a free state and is between the public rail 5 and the locking plate 1.

[0028] S4. Pull the spring 4 out of the connecting hole 51 of the public rail 5 and release it after rotating the spring 4 90°. The protrusion 41 abuts against the surface of the public rail 5A. At this time, the spring 4 is in a stretched state.

[0029] S5. The locking box 2 passes through the connecting hole 51 from A to A' and is mounted on the public rail 5. The locking box 2 can restrict the rotation of the spring 4, protect the spring 4 from falling out of the hole of the public rail 5, prevent the pin from rotating and moving after unlocking, and also protect the lock plate 1 from being over-unlocked.

[0030] When the locking shaft 3 is pressed in the direction of A', the locking plate 1 is unlocked. After the locking shaft 3 is released, due to the elastic force of the spring 4, the locking shaft 3 returns to the A direction, and the locking plate 1 returns to the locked state.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
