Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] In the description of this technology, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technology based on the specific circumstances.

[0025] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0026] Please see Figure 1-5 This utility model discloses a rear-end connection assembly for a car seat slide rail, comprising a car connecting plate 1, a guide rail connecting plate 3, a support arm 2, a cover plate 10, and a locking device. The support arm 2 is integrally formed between the car connecting plate 1 and the guide rail connecting plate 3. The guide rail connecting plate 3 has mounting holes for connecting with the guide rail at the bottom of the car seat. The upper surface of the car connecting plate 1 has a waist-shaped hole 4 in the middle for connecting with the sheet metal part of the car floor by bolts. Both sides of the car connecting plate 1 are integrally formed with side skirts 5. The cover plate 10 is movably inserted into the top of the car connecting plate 1. The locking device includes a lock cylinder structure and a lock tongue structure. The lock cylinder structure is rotatably connected to the upper surface of the cover plate 10, and the lock tongue structure is fixedly connected to the upper surface of the car connecting plate 1.

[0027] In this embodiment, the lock cylinder structure is movably inserted into the lock tongue structure. The lock cylinder structure includes a knob 11, a connecting post 12 is fixedly connected to the center of the lower surface of the knob 11, and a lock block 13 is fixedly connected to the bottom end of the connecting post 12. The lock tongue structure includes a positioning post 7, which is fixedly connected to the upper surface of the vehicle connecting plate 1. A lock hole 9 is provided in the inner cavity of the positioning post 7 near the bottom. An insertion hole 8 communicating with the lock hole 9 is provided in the middle of the upper surface of the positioning post 7 along the vertical direction. A mounting groove is provided on the upper surface of the cover plate 10. A first rubber ring 15 is fixedly connected to the inner wall of the mounting groove. The knob 11 is rotatably connected to the inside of the mounting groove. The outer side of the knob 11 fits against the inner side of the rubber ring. A handle 14 is fixedly connected to the middle of the upper surface of the knob 11.

[0028] With the above technical solution, after the staff inserts the cover plate 10 above the car connecting plate 1, the locking block 13 passes through the insertion hole 8 and enters the lock hole 9. After the staff rotates the knob 11 90°, the locking block 13 cannot be pulled out of the lock hole 9, which has the effect of limiting the vertical and horizontal directions of the cover plate 10 and preventing the cover plate 10 from falling off the car connecting plate 1.

[0029] In this embodiment, a sealing block 18 is fixedly connected to the center of the bottom of the cover plate 10 and near both ends. The sealing block 18 is inserted between the two side skirts 5. With the two sealing blocks 18, the cover plate 10 can achieve all-round sealing protection for exposed bolts, effectively isolate water vapor and corrosive media, and solve the corrosion problem caused by traditional exposed bolts.

[0030] In this embodiment, a through hole is provided at the position corresponding to the center of the mounting groove on the cover plate 10. A second rubber ring 16 is fixedly connected to the inner wall of the through hole. The end of the connecting post 12 passes through the through hole, and the surface of the connecting post 12 is in contact with the inner wall of the second rubber ring 16.

[0031] By setting the first rubber ring 15 and the second rubber ring 16, the friction force on the knob 11 and the connecting post 12 can be increased, preventing the knob 11 and the connecting post 12 from rotating unexpectedly under natural conditions, and ensuring the stability of the locking block 13.

[0032] It should be noted that the locking block 13 has a cuboid structure, and the length of the locking block 13 is greater than the width of the locking block 13. The shape and structure of the socket 8 are adapted to the shape and structure of the locking block 13. The locking block 13 passes through the socket 8 and extends into the interior of the lock hole 9.

[0033] Therefore, after the locking block 13 is inserted into the lock hole 9, the operator only needs to hold the handle 14 and rotate it 90° to turn the locking block 13 horizontally. At this time, the locking block 13 can no longer pass through the insertion hole 8, thus achieving the locking effect.

[0034] Please refer to 1. In this embodiment, there are two locking devices. The two positioning pins 7 are fixedly connected to the upper surface of the car connecting plate 1 and are located near the two sides of the waist-shaped hole 4. The position of the locking block 13 on the cover plate 10 corresponds to the position of the insertion hole 8 on the positioning pin 7. By setting two locking devices on both sides, the force distribution of the cover plate 10 after locking can be optimized, making the cover plate 10 more stable.

[0035] In some other embodiments, the outer side of the side skirt 5 is integrally formed with a recess 6, and a locking block 17 is fixedly connected to the inner wall of the cover plate 10 at a position corresponding to the recess 6, and the locking block 17 is inserted into the interior of the recess 6.

[0036] The above technical solution can provide secondary protection for the cover plate 10, and can still maintain the connection of the cover plate 10 when the locking device fails unexpectedly.

[0037] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
