[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] The following describes an embodiment of the present invention based on its overall structure.

[0028] Example 1:

[0029] A car seat inner lock type slide rail, such as Figure 1-Figure 4As shown, it includes a slide rail body 1, a pull rod device 2 is provided on one side of the slide rail body 1, the pull rod device 2 includes a first pull rod 21 connected to the unlocking structure and a second pull rod 22 held by a person's hand, a conversion mechanism 23 is provided between the first pull rod 21 and the second pull rod 22, and the conversion mechanism 23 includes a frame 231 separated from the slide rail body 1, and a first gear block 232 and a second gear block 233 are rotatably connected to the frame 231;

[0030] The top two sides of the frame 231 are slidably connected with locking cards 234. The frame 231 in the conversion mechanism 23 is separated from the slide rail body 1, which not only simplifies the installation and maintenance process, but also realizes precise transmission and stable unlocking action through the first tooth block 232 and the second tooth block 233 rotatably connected on the frame 231. The locking cards 234 slidably connected on both sides of the top of the frame 231 provide solid support and locking effect for the entire conversion mechanism. When the locking card 234 slides to the predetermined position, it can effectively fix the frame 231 or the tooth block to prevent shaking or deviation during the unlocking process, thereby further improving the stability and safety of the seat slide.

[0031] See Figure 3 A fixing plate 235 is provided at the relative position of the locking card 234. The fixing plate 235 is fixedly connected to the slide rail body 1. The fixed connection between the fixing plate 235 and the slide rail body 1 also provides additional structural strength for the entire pull rod device 2. During the unlocking or locking process, this strong connection can effectively resist the stress generated, thereby ensuring the normal operation of the pull rod device 2.

[0032] See Figure 3 The first tooth block 232 and the second tooth block 233 are engaged with each other, the first tooth block 232 and the first pull rod 21 are fixedly connected, and the second tooth block 233 and the second pull rod 22 are fixedly connected. The fixed connection between the first tooth block 232 and the first pull rod 21, and the fixed connection between the second tooth block 233 and the second pull rod 22 further enhance the structural stability and reliability of the conversion mechanism 23.

[0033] See Figure 3 The first tooth block 232 and the second tooth block 233 are both provided with a first card slot 236, and the first card slot 236 is adapted to one end of the locking card 234. The user can choose different unlocking methods by sliding the locking card 234 according to needs, and the presence of the first card slot 236 ensures that the locking card 234 can firmly fix the tooth block so that it will not rotate due to external force, so that the pull rod device 2 can adapt to the operating habits and needs of different users, thereby improving the applicability and user satisfaction of the product.

[0034] The implementation principle of the present utility model is as follows: first, the conversion mechanism 23 can be used to switch the unlocking direction;

[0035] When the user selects to unlock by pulling the lever downward, the locking card 234 is slid. The locking card 234 and the fixing plate 235 engage with each other, thereby engaging the frame 231. When the second pull rod 22 is pulled downward, the second tooth block 233 rotates, driving the first tooth block 232 to rotate downward, thereby driving the first pull rod 21 to rotate around the fulcrum 3, thereby unlocking the door.

[0036] When you choose to unlock by pulling it upward, slide the locking card 234 so that the locking card 234 is locked in the first slot 236, so that the first tooth block 232 and the second tooth block 233 and the frame 231 are fixed to form an immovable whole. At this time, when you pull the second pull rod 22 upward, you can drive the first pull rod 21 to rotate around the fulcrum 3 to achieve unlocking.

[0037] Example 2:

[0038] See Figure 1 、 Figure 2 and Figure 3 A second slot 237 is provided on the frame 231, and a third slot 238 is provided on the fixing plate 235. The third slot 238 on the fixing plate 235 cooperates with other structures on the slide rail body 1 or the frame 231 to provide an additional fixing point for the entire pull rod device 2. Through the snapping action of the third slot 238, the fixing plate 235 can be fixed more firmly.

[0039] See Figure 1 、 Figure 2 and Figure 3 There are two card blocks 239 fixedly connected to the locking card 234, and the card block 239 is adapted to the second card slot 237 and the third card slot 238. When the locking card 234 is fixedly connected through the third card slot 238, the card block 239 can be tightly inserted into the third card slot, ensuring that the locking card 234 is firmly fixed in the predetermined position.

[0040] The implementation principle of the present invention is as follows: first, through the adaptation of the card block 239 and the second card slot 237 and the third card slot 238, when the locking card 234 slides to the specified position, it can be firmly fixed to prevent sliding.
