[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners.

[0041] Please refer to Figures 1 - 9 , in the embodiment of the present invention, an adjustable-height automobile seat belt connecting slider includes a seat belt guide ring 1, a slide rail 2, and a hollow slider 3 that slidably cooperates with the slide rail 2. An angle adjustment mechanism is provided between the slide rail 2 and the hollow slider 3. The seat belt guide ring 1 is disposed on the hollow slider 3 through the angle adjustment mechanism. During the sliding process of the hollow slider 3 on the slide rail 2, the angle adjustment mechanism will drive the seat belt guide ring 1 to perform corresponding deflection;

[0042] A locking mechanism is further provided between the slide rail 2 and the hollow slider 3. The locking mechanism can lock the hollow slider 3 on the slide rail 2;

[0043] A switch assembly is disposed on the hollow slider 3. The switch assembly is connected to the locking mechanism. The locking mechanism can be unlocked from the hollow slider 3 under the action of the switch assembly, so as to realize the height adjustment of the hollow slider 3 on the slide rail 2.

[0044] In this solution, the locking mechanism and the switch assembly are cooperatively arranged to enable the switching between the locked state and the unlocked state of the hollow slider 3 and the slide rail 2, so as to facilitate the rapid height adjustment of the hollow slider 3. During the ascending or descending process of the hollow slider 3, the angle adjustment mechanism will drive the seat belt guide ring 1 to deflect at an adapted angle, so that the seat belt can fit the human body more closely, which not only increases the comfort when wearing the seat belt, but also improves the safety performance.

[0045] As a further solution of the present utility model, the angle adjustment mechanism includes a first gear 4 vertically rotatably arranged on the hollow slider 3. The seat belt guide ring 1 is arranged on the first gear 4, and the seat belt guide ring 1 is located outside the hollow slider 3.

[0046] In this embodiment, since the first gear 4 is vertically rotatably arranged on the hollow slider 3 and the seat belt guide ring 1 is arranged on the first gear 4, when the first gear 4 rotates, the seat belt guide ring 1 will deflect at a certain angle following the first gear 4, so that the seat belt fits the human body more closely under the action of the seat belt guide ring 1.

[0047] As a further solution of the present utility model, the angle adjustment mechanism further includes a U-shaped frame 5 arranged inside the hollow slider 3. A second gear 6 meshing with the first gear 4 is rotatably arranged on the U-shaped frame 5;

[0048] A toothed plate 7 is arranged on the slide rail 2, and the second gear 6 meshes with the toothed plate 7.

[0049] In this embodiment, as Figure 4 shown, when the hollow slider 3 slides upward, since the second gear 6 meshes with the toothed plate 4, the second gear 6 will rotate clockwise. Also, because the first gear 4 meshes with the second gear 6, the first gear 4 will rotate counterclockwise, so that the seat belt guide ring 1 deflects downward, causing the seat belt to be pressed against the human body by the seat belt guide ring 1, and improving the fitting degree between the seat belt and the human body;

[0050] Similarly, when the hollow slider 3 slides downward, the seat belt guide ring 1 will deflect upward to avoid excessive pressure on the human body caused by the seat belt;

[0051] Wherein, the diameter of the first gear 4 is larger than the diameter of the second gear 6.

[0052] As a further solution of the present utility model, the locking mechanism includes a sleeve 8 arranged inside the hollow slider 3 and a slide rod 9 slidably matched with the sleeve 8;

[0053] A spring 10 is installed inside the sleeve 8, and both ends of the spring 10 are abutted against the inner wall of the sleeve 8 and one end of the sliding rod 9 respectively.

[0054] In this embodiment, as Figure 4 shown, due to the existence of the spring 10 and being in a compressed state, and the sleeve 8 and the sliding rod 9 being in sliding fit with each other, therefore, in the absence of external force, the sliding rod 9 will always have a tendency to move towards the sliding rail 2.

[0055] As a further solution of the present invention, the locking mechanism further includes a moving plate 12 and sliding grooves 11 respectively opened at the top and bottom inside the hollow slider 3. Both ends of the moving plate 12 are located in the two sliding grooves 11 and are in sliding fit with each other. The other end of the sliding rod 9 is connected to one side wall of the moving plate 12;

[0056] A plurality of teeth 13 are uniformly arranged along the length direction on the other side of the moving plate 12. A locking tooth 14 adapted to the plurality of teeth 13 is arranged on the sliding rail 2. Among them, the locking tooth 14 is located between two adjacent teeth 13 and is buckled with each other.

[0057] In this embodiment, since the sliding rod 9 always has a tendency to move towards the sliding rail 2, and the moving plate 12 is in sliding fit with the sliding groove 11, therefore, the moving plate 12 will always have a tendency to move towards the sliding rail 2 under the drive of the sliding rod 9;

[0058] Since the locking tooth 14 is located between two adjacent teeth 13 and is buckled with each other, therefore, the hollow slider 3 cannot slide on the sliding rail 2, achieving the purpose of locking the hollow slider 3 on the sliding rail 2.

[0059] As a further solution of the present invention, both the locking tooth 14 and the plurality of teeth 13 are in a "triangle" shape composed of two inclined surfaces at the mutually approaching ends.

[0060] In this embodiment, since both the locking tooth 14 and the plurality of teeth 13 are in a "triangular" shape composed of two inclined surfaces at the mutually approaching ends, it enables the locking tooth 14 and the plurality of teeth 13 to be smoothly misaligned and buckled, avoiding the situation of jamming.

[0061] As a further solution of the present invention, the switch assembly includes a bracket 15 arranged inside the hollow slider 3 and a rotating rod 16 horizontally rotatably arranged on the hollow slider 3 and the bracket 15. And the rotating rod 16 is in rotational fit with the moving plate 12. A spiral groove 17 is opened on the outer wall of the rotating rod 16;

[0062] A first ball 18 is rollingly fitted inside the moving plate 12, and the first ball 18 is also rollingly fitted inside the spiral groove 17.

[0063] In this embodiment, since the first ball 18 is rollingly fitted inside the moving plate 12 and also rollingly fitted inside the spiral groove 17, when the rotating rod 16 rotates, the moving plate 12 will drive the plurality of teeth 13 to separate from the locking teeth 14, thereby releasing the locking of the hollow slider 3 and the slide rail 2, and the hollow slider 3 can be slid. During this process, the spring 10 will be further compressed.

[0064] As a further solution of the present utility model, the switch assembly further includes a button 19 slidably disposed on the rotating rod 16. A limiting rod 20 is horizontally disposed on one side of the button 19, and one end of the limiting rod 20 penetrates through the hollow slider 3 and extends into its interior;

[0065] A second ball 21 is rollingly fitted inside the button 19, and the second ball 21 is also rollingly fitted inside the spiral groove 17.

[0066] In this embodiment, when the height of the hollow slider 3 needs to be adjusted, the button 19 is pushed by an external force, so that the button 19 moves towards the hollow slider 3. During this process, the limiting rod 20 will slidably cooperate with the hollow slider 3. Due to the action of the limiting rod 20, the button 19 can only slide and cannot rotate. Also, because the second ball 21 is rollingly fitted inside the button 19 and the second ball 21 is also rollingly fitted inside the spiral groove 17, the rotating rod 16 will rotate during the process of pushing the button 19.
