[0028] In order to make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present utility model, rather than 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 efforts fall within the protection scope of the present utility model.

[0029] As shown in an embodiment of the present utility model Figures 1 to 7 a seat back hook bracket includes a base 1 installed on the seat back. A first hook 2 and a second hook 3 that can be flipped open or retracted relative to the base 1 are respectively provided on the base 1. The second hook 3 is slidably disposed on the base 1 up and down through a sliding mechanism, and the sliding mechanism is also positioned through a positioning mechanism to adjust the position height of the second hook 3 on the base 1 through the sliding mechanism and the positioning mechanism.

[0030] In this embodiment, the base 1 includes a front side plate 11 and a rear side plate 12. The upper ends of the front side plate 11 and the rear side plate 12 are integrally connected, so that a card slot 101 is formed between the front side plate 11 and the rear side plate 12, and the slot opening of the card slot 101 faces downward. Both the first hook 2 and the second hook 3 are provided on the front surface of the front side plate 11. Among them, the front side plate 11 and the rear side plate 12 have the same shape, and both the front side plate 11 and the rear side plate 12 are long spindle-shaped plates. Specifically, the lower edge of the front side plate 11 is straight and the two ends are curved upward in an arc shape, and the upper edge of the front side plate 11 is straight and the two ends are curved downward in an arc shape. The rear side plate 12 is basically the same as the front side plate 11, and the difference between the two is that a notch 120 is provided in the middle of the rear side plate 12, and the notch 120 serves as an avoidance opening to facilitate the smooth insertion of the rear side plate 12 into the card slot on the back of the car seat. A non-slip gasket (not shown in the drawings) is provided in the middle of the rear surface of the front side plate 11, and the non-slip gasket (not shown in the drawings) corresponds to the notch 120. The non-slip gasket (not shown in the drawings) is, for example, a rubber gasket.

[0031] In this embodiment, a convex shell 6 is provided on the front surface of the front side plate 11. The shape of the convex shell 6 matches that of the front side plate 11, that is, it is also spindle-shaped, and the outer surface of the convex shell 6 is a smooth arc-shaped convex. A first groove 601 and a second groove 602 are respectively provided on the convex shell 6. The first groove 601 correspondingly houses the first hook 2, and the second groove 602 correspondingly houses the second hook 3. After the first hook 2 and the second hook 3 are folded and retracted, they have a hidden storage appearance effect on the convex shell 6, and can also effectively avoid the risk of collision, and the use safety is better.

[0032] In this embodiment, the sliding mechanism includes a sliding plate 4, and a vertical hollow groove 401 is formed in the middle of the sliding plate 4. The positioning mechanism includes a clamping projection 5. On both sides of the sliding plate 4 at the vertical groove walls located within the hollow groove 401, a plurality of clamping projections 5 are respectively provided. The plurality of clamping projections 5 on the same side are arranged at intervals from top to bottom in sequence, and the plurality of clamping projections 5 on both sides correspond to each other in pairs to form a plurality of clamping and fixing areas within the hollow groove 401 of the sliding plate 4. A guiding column 7 is provided within the second groove 602. The guiding column 7 passes through the hollow groove 401 and is clamped in one of the clamping and fixing areas accordingly. The sliding plate 4 can slide up and down relative to the guiding column 7. The rear end of the guiding column 7 is fixedly arranged on the inner surface of the second groove 602, the front end of the guiding column 7 passes through the hollow groove 401 and is located on the front side of the sliding plate 4, and a limiting block 8 opposite to the sliding plate 4 is further provided at the front end of the guiding column 7. Among them, the guiding column 7 plays a guiding and limiting role in the sliding of the sliding plate 4, and the function of the limiting block 8 is to prevent the sliding plate 4 from detaching from the guiding column 7. The limiting block 8 and the guiding column 7 are fixedly connected by screws, which is convenient for disassembly, and thus facilitates the sliding plate 4 to be sleeved on the guiding column 7. The overall shape of the limiting block 8 and the guiding column 7 after connection is T-shaped, which can not only provide space for the sliding of the sliding plate 4, but also play a limiting role in the up, down and front directions of the sliding of the sliding plate 4.

[0033] For example, two clamping projections 5 are respectively provided on the left and right vertical groove walls of the sliding plate 4 located within the hollow groove 401 to form three clamping and fixing areas within the hollow groove 401 of the sliding plate 4. When the lowermost clamping and fixing area within the hollow groove 401 clamps the guiding column 7, the sliding plate 4 is in the initial position. When the sliding plate 4 is pulled down forcefully, the clamping and fixing area changes, and the sliding plate 4 can be moved downwards to adjust the position height of the sliding plate 4. Through the abutting and clamping cooperation of the corresponding plurality of clamping projections on both sides with the guiding column 7, stable positioning of the sliding plate 4 is achieved. If the position height of the sliding plate 4 on the convex shell 6 is different, then correspondingly, the position height of the second hook 3 is also different.

[0034] In this embodiment, the rotating connecting piece is a rotating shaft for example. Among them, first mounting holes are correspondingly formed in the lower parts of the two opposite inner side walls of the first groove 601. There are two rotating shafts, and the two rotating shafts are correspondingly arranged on the two outer side walls at the lower end of the first hook 2 for correspondingly inserting into the first mounting holes on the same side, so that the first hook 2 can be flipped open by a first angle to achieve the hooking function.

[0035] A horizontal first mounting portion for inserting the rotating shaft is provided at the lower end of the sliding plate 4, and a horizontal second mounting portion for inserting the rotating shaft is provided at the lower end of the second hook 3. A bayonet for the first mounting portion to be inserted into is formed in the middle of the second mounting portion. After the first mounting portion is inserted into the bayonet, the first mounting portion and the second mounting portion can be rotationally connected by the rotating shaft, so that the second hook 3 can be flipped open by a second angle to achieve the hooking function.

[0036] It should be noted that the above structures for enabling the first hook 2 to pass through the rotating shaft and the first mounting hole and enabling the second hook 3 to pass through the rotating shaft, the first mounting portion and the second mounting portion to achieve angle-limited rotational connection are relatively common in the art. In actual applications, any suitable rotational connection structure in the prior art can be adopted, as long as it can achieve angle-limited flipping connection. Only an example is given in this embodiment and it does not constitute a specific limitation; the magnitude of the rotational damping of the first hook 2 and the second hook 3 can be designed and selected according to actual requirements.

[0037] It can be understood that the first angle and the second angle can be the same or different, and the flipping degrees of the first hook 2 and the second hook 3 can be the same or different, as long as the hooking function can be achieved. For example, if both the first angle and the second angle are 45°, then the flipping degrees of the first hook 2 and the second hook 3 are the same. Or, if the first angle is 45° and the second angle is 60°, then the flipping degrees of the first hook 2 and the second hook 3 are different. Therefore, the differences in the flipping degrees of the first hook 2 and the second hook 3 can all be achieved through corresponding existing structures.

[0038] In this embodiment, a limiting convex block 6011 is provided in the first groove 601. The limiting convex block 6011 does not protrude from the first groove 601. The side of the first hook 2 opposite to the limiting convex block 6011 has an arc-shaped retaining arm 21. There are two arc-shaped retaining arms 21, and the two arc-shaped retaining arms 21 are correspondingly arranged at two opposite edges of the first hook. Notches 210 adapted to the limiting convex block 6011 are formed on the edges of the two arc-shaped retaining arms 21. The depression arc of the notch 210 is adapted to the convex shell arc of the limiting convex block 6011. The setting of the notch 210 can further improve the stability of hooking and effectively prevent the item from falling, while the setting of the limiting convex block 6011 is convenient for the first hook 2 to be buckled thereon through the notch 210.

[0039] Furthermore, a plurality of first grooves 601 are provided. The plurality of first grooves 601 are arranged side by side and spaced apart one by one along the length direction of the convex shell 6. For example, in this embodiment, three first grooves 601 are provided. The three first grooves 601 are arranged side by side and spaced apart. Each first groove 601 is connected with a first hook 2 through a rotating connecting member. The number of first hooks 2 corresponds to the number of first grooves 601 one by one. In order to facilitate the operation of flipping and opening the first hook 2, a first depression is formed at the upper edge of each first groove 601 so that a finger can be inserted to pry out the first hook 2.

[0040] Further, a plurality of second grooves 602 are provided. The plurality of second grooves 602 are arranged side by side and spaced apart one by one along the length direction of the convex shell 6, and each second groove 602 is correspondingly located between two adjacent first grooves 601. For example, in this embodiment, two second grooves 602 are provided. The two second grooves 602 are arranged side by side and spaced apart, and the two second grooves 602 and the three first grooves 601 are alternately distributed one by one. A second hook 3 is connected in each second groove 602 through a sliding mechanism, and the number of the second hooks 3 corresponds to the number of the second grooves 602 one by one. In order to facilitate the operation of flipping and opening the second hook 3, a second recess is also provided at the upper edge of each second groove 602 so that a finger can be inserted to pull out the second hook 3.

[0041] It should be noted that the weights of the objects that the first hook 2 and the second hook 3 can hook should not be too heavy, and their use effects are better within a reasonable weight range.

[0042] By adopting the seat back hook bracket of the embodiment of the present utility model, the base 1 is adaptively installed at, for example, the clamping slot of the seat back of a Tesla car, and the clamping slot is as shown in the attached Figure 8 installation position indicated by the arrow A. During installation, the rear side plate 12 is snapped into the clamping slot, and the front side plate 11 correspondingly fits on the outer surface of the seat back. The shapes of the front side plate 11 and the rear side plate 12 are designed to exactly match the trend of the edge of the clamping slot. Therefore, the spatial shape of the card slot 101 also matches it, so that the base 1 can be stably installed on the seat back, and the setting of the anti-slip gasket (not shown in the attached drawing) can further increase the stability of the installation of the base 1, and the base 1 is not easy to loosen and fall off.

[0043] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
