[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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model 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 6 a seat back hook bracket includes a base 1 installed on the seat back. A hook 2 is provided on the base 1. The lower end of the base 1 has a card slot 101. An installation seat 3 is provided at the upper end of the base 1. A clamping plate 4 is provided on the installation seat 3. The clamping plate 4 makes a telescopic movement relative to the installation seat 3. When the base 1 is installed on the seat back through the card slot 101, the clamping plate 4 gradually approaches the installation seat 3 and presses tightly against the seat back.

[0030] In this embodiment, the base 1 includes a first plate body 11, a second plate body 12 and a connecting strip 13. The first plate body 11 and the second plate body 12 are parallel to each other. The upper ends of the first plate body 11 and the second plate body 12 are connected by the connecting strip 13. A clamping groove 101 is formed by enclosing between the first plate body 11, the second plate body 12 and the connecting strip 13. The base 1 is clamped and fixed on the plastic backboard of the seat back through the clamping groove 101. Specifically, the first plate body 11, the second plate body 12 and the connecting strip 13 are integrally connected. The first plate body 11 and the second plate body 12 have the same shape, and both the first plate body 11 and the second plate body 12 are long strip-shaped shuttle plates. Among them, the lower edges of the first plate body 11 and the second plate body 12 are both straight and the two ends are arc-shaped bent upward, and the upper edges of the first plate body 11 and the second plate body 12 are both straight and the two ends are arc-shaped bent downward. The bending radian of the connecting strip 13 is the same as the upper edge of the first plate body 11 and the second plate body 12. The mounting seat 3 is arranged in the middle of the connecting strip 13. An avoidance opening 120 corresponding to the clamping plate 4 and accommodating the clamping plate 4 is formed in the middle of the second plate body 12. The avoidance opening 120 communicates with the clamping groove 101, which is convenient for the clamping plate 4 to directly contact the plastic backboard of the seat back, not only facilitating the accommodation of the clamping plate 4, but also saving the manufacturing material of the clamping plate 4 and reducing the production cost.

[0031] It should be noted that the length of the clamping plate 4 is such that it can contact the plastic backboard of the seat back and abut against it.

[0032] In this embodiment, the mounting seat 3 is located in the middle of the connecting strip 13, and the clamping plate 4 is located on the side of the second plate body 12 facing away from the first plate body 11. A telescopic driving mechanism is provided on the mounting seat 3. The clamping plate 4 is connected to the telescopic driving mechanism. The telescopic driving mechanism drives the clamping plate 4 to move in a direction close to or away from the mounting seat 3. When the clamping plate 4 gradually moves in a direction close to the mounting seat 3, a tightening force will gradually be generated between the clamping plate 4 and the plastic backboard of the seat back, so that the base 1 can be stably installed on the plastic backboard of the seat back.

[0033] Specifically, the mounting base 3 has a cavity. The telescopic driving mechanism includes a knob 51 and a screw rod 52 disposed inside the mounting base 3. A through groove 301 is formed on the upper side of the mounting base 3, and the knob 51 partially extends out of the mounting base 3 through the through groove 301 to facilitate the operation and control of the rotation of the knob 51. The clamping plate 4 is provided with a threaded hole column 41 and a guide post 42 extending into the mounting base 3. On the surface of the mounting base 3 opposite to the clamping plate 4, a first through hole 302 for inserting the threaded hole column 41 and a second through hole 303 for inserting the guide post 42 are respectively formed. There is one threaded hole column 41 corresponding to the screw rod 52, and the number of the first through holes 302 is the same as that of the threaded hole column 41. One end of the screw rod 52 is fixedly connected to the knob 51, and the other end of the screw rod 52 is threadedly connected to the threaded hole column 41. Among them, there are two guide posts 42, and the number of the second through holes 303 is the same as that of the guide posts 42. The two guide posts 42 are correspondingly located on both sides of the threaded hole column 41 and both extend into the mounting base 3. The two guide posts 42 move along with the movement of the clamping plate 4, mainly for guiding and limiting. When the screw rod 52 is rotated by rotating the knob 51, the screw rod 52 drives the threaded hole column 41 to move, and under the guiding and limiting action of the guide posts 42, the clamping plate 4 moves relative to the mounting base 3.

[0034] Specifically, on the surface of the mounting base 3 opposite to the first through hole 302, an annular flange 31 is provided, and the annular flange 31 corresponds to the first through hole 302. A first groove 510 for accommodating the annular flange 31 is formed on the surface of the knob 51 facing the annular flange 31. The knob 51 is rotationally limited and arranged on the annular flange 31 through the first groove 510, so that the knob 51 can rotate stably.

[0035] In this embodiment, a second groove 401 is formed at a lower position on the surface of the clamping plate 4 facing away from the mounting base 3. The second groove 401 is horizontally arranged. At a lower position on the surface of the clamping plate 4 facing the mounting base 3, a convex bump 402 corresponding to the second groove 401 is provided, which is used to tightly press against the plastic backboard of the seat back.

[0036] In this embodiment, a convex shell 6 is provided on the surface of the first plate body 11 facing away from the second plate body 12. The shape of the convex shell 6 matches that of the first plate body 11, that is, it is also fusiform. The outer surface of the convex shell 6 is in a smooth arc-shaped convex state. A plurality of third grooves 601 are formed on the convex shell 6. The plurality of third grooves 601 are arranged side by side and at intervals. Each third groove 601 is provided with a hook 2. The hook 2 can be flipped open or retracted, achieving an appearance effect of hidden storage on the convex shell 6, and can also effectively avoid the risk of collision, with better use safety.

[0037] For example, if three third grooves 601 are formed, correspondingly, the number of the hooks 2 is three. Among them, the middle hook 2 is slidably positioned up and down in the corresponding third groove 601 through a sliding positioning mechanism.

[0038] Specifically, the sliding positioning mechanism includes a sliding plate 7. A vertical hollow groove 701 is formed in the middle of the sliding plate 7. On both vertical groove walls of the sliding plate 7 located within the hollow groove 701, two clamping bumps 702 are respectively provided. Multiple clamping bumps 702 on the same side are arranged at intervals from top to bottom in sequence. Multiple clamping bumps 702 on both sides correspond to each other in pairs to form multiple clamping and fixing areas within the hollow groove 701 of the sliding plate 7. Among them, a convex post 72 is provided on the inner side wall of the middle third groove 601. The convex post 72 passes through the hollow groove 701 and is correspondingly clamped in one of the clamping and fixing areas. The sliding plate 7 can slide up and down relative to the convex post 72. A limiting block 73 opposite to the sliding plate 7 is provided at one end of the convex post 72 passing through the hollow groove 701. The convex post 72 plays a guiding and limiting role in the sliding of the sliding plate 7. The function of the limiting block 73 is to prevent the sliding plate 7 from separating from the convex post 72. The limiting block 73 and the convex post 72 are fixedly connected by screws, which is convenient for disassembly so that the sliding plate 7 can be sleeved on the convex post 72. The overall shape of the limiting block 73 and the convex post 72 after connection is T-shaped, which can not only provide space for the sliding of the sliding plate 7 but also limit the sliding of the sliding plate 7. By setting the sliding positioning mechanism, the flexibility of the hook 2 in use is increased, meeting different usage requirements of users.

[0039] In this embodiment, the lower parts of the two hooks 2 that do not slide through the sliding positioning mechanism are rotatably connected to the corresponding third grooves 601 through rotating shafts. Specifically, taking one of the hooks 2 as an example for illustration, at the lower parts of two opposite inner side walls of the third groove 601, first mounting holes 6011 are correspondingly formed. There are two rotating shafts, and the two rotating shafts are correspondingly arranged on the outer side walls at the lower ends of the hook 2 for correspondingly inserting into the first mounting holes 6011 on the same side, so that the hook 2 can be flipped open at a first angle to achieve the hooking function.

[0040] In this embodiment, the lower part of the middle hook 2 that slides through the sliding positioning mechanism is rotatably connected to the lower part of the sliding plate 7 through a rotating shaft. Specifically, a horizontal first mounting portion 711 for inserting the rotating shaft is provided at the lower end of the sliding plate 7. A horizontal second mounting portion 211 for inserting the rotating shaft is provided at the lower end of the hook 2. A bayonet 2110 for the first mounting portion 711 to be inserted into is formed in the middle of the second mounting portion 211. After the first mounting portion 711 is inserted into the bayonet 2110, the first mounting portion 711 and the second mounting portion 211 can be rotatably connected through the rotating shaft, so that the hook 2 can be flipped open at a second angle to achieve the hooking function.

[0041] It should be noted that the structures of limiting the angle of rotation connection of the corresponding hooks through the rotating shaft and the first mounting hole 6011, and through the rotating shaft, the first mounting portion 711 and the second mounting portion 211 are relatively common in the prior art. In actual applications, any suitable rotating connection structure in the prior art can be adopted, as long as it can achieve the limiting-angle flipping connection. Only examples are provided in this embodiment and do not constitute specific limitations; the magnitude of the rotational damping of each hook 2 can be designed and selected according to actual requirements.

[0042] It can be understood that the first angle and the second angle can be the same or different, that is, the flipping degrees of each hook 2 can be the same or different, as long as the hooking function can be achieved.

[0043] Furthermore, avoidance depressions 90 are provided at the upper ends of the first plate body 11 and the convex shell 6, and the lower end of the mounting seat 3 is placed in the avoidance depression 90. Through reasonable space design, the overall aesthetic effect is guaranteed.

[0044] Using the seat back hook bracket of the embodiment of the present utility model, the base 1 is adaptively installed at the clamping slot of the seat back of, for example, a Tesla car, and the clamping slot is as shown in the attached Figure 7 installation position indicated by the arrow A. During installation, the second plate body 12 is snapped into the clamping slot, and then fixed to the upper part of the plastic backboard through the clamping slot 101. Then, the first plate body 11 is correspondingly attached to the outer surface of the plastic backboard. Then, the position of the clamping plate 4 is adjusted by the knob 51, so that the clamping plate 4 gradually approaches the mounting seat 3 and finally presses tightly against the plastic backboard, and thus the base 1 can be stably installed. The shapes of the first plate body 11, the second plate body 12 and the connecting strip 13 are designed to exactly match the trend of the edge of the clamping slot. Therefore, the spatial shape of the clamping slot 101 also matches it. The inner surfaces of the first plate body 11, the second plate body 12 and the connecting strip 13 are all smooth surfaces, which is convenient for the clamping slot 101 to be smoothly snapped in.

[0045] In some other embodiments, in order to further increase the installation stability of the base 1, an anti-slip gasket (not shown in the drawings) can also be provided at the position corresponding to the avoidance opening 120 on the first plate body 11, so that the first plate body 11 can be more stably attached to the outer surface of the plastic backboard.

[0046] It should be understood that those of ordinary skill in the art can make improvements or changes according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of the present utility model.
