Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] As shown in the embodiments of the present utility model Figures 1 to 7 a seat back hook bracket includes a base 1 installed on the seat back. The base 1 includes a first plate body 11 and a second plate body 12 arranged in parallel. The upper ends of the first plate body 11 and the second plate body 12 are connected. A card slot 101 is formed between the first plate body 11 and the second plate body 12. On one side surface of the first plate body 11 facing away from the second plate body 12, a first hook 2 and two clamping arms 3 are provided. The two clamping arms 3 are arranged oppositely. The first hook 2 is located between the two clamping arms 3. The first hook 2 and the two clamping arms 3 can be flipped open or retracted relative to the first plate body 11. The flipping directions of the two clamping arms 3 are both perpendicular to the flipping direction of the first hook 2. After the two clamping arms 3 and the first hook 2 are flipped open, a clamping space for clamping an electronic device is formed between the two clamping arms 3 and the first hook 2.

[0031] In this embodiment, the base 1 further includes a connecting strip 13. The upper ends of the first plate body 11 and the second plate body 12 are integrally connected through the connecting strip 13. A card slot 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 card slot 101. Among them, 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 spindle plates. Specifically, the lower edges of the first plate body 11 and the second plate body 12 are both linear and their two ends are curved upward in an arc shape. The upper edges of the first plate body 11 and the second plate body 12 are both linear and their two ends are curved downward in an arc shape. The bending radian of the connecting strip 13 is the same as the upper edges of the first plate body 11 and the second plate body 12.

[0032] Further, in this embodiment, a convex shell 4 is further provided on the surface of the first plate body 11 facing away from the second plate body 12 (i.e., on the outer surface of the first plate body 11). The shape of the convex shell 4 matches that of the first plate body 11, that is, it is also spindle-shaped. The outer surface of the convex shell 4 is a smooth arc-shaped convex surface. The first hook 2 and the two clamping arms 3 are respectively rotatably provided on the convex shell 4. Two first grooves 401 for accommodating the two clamping arms 3 and a second groove 402 for accommodating the first hook 2 are correspondingly provided on the convex shell 4; the size of the first groove 401 is adapted to the clamping arm 3, and the size of the second groove 402 is adapted to the first hook 2. Wherein, two first through grooves 403 are respectively provided on the convex shell 4. The two first through grooves 403 are correspondingly located on one side of the two first grooves 401 away from the second groove 402 respectively, and the two first through grooves 403 are correspondingly communicated with the two first grooves 401; a slider 41 that slides horizontally and is limited is respectively provided in the two first through grooves 403, and the two clamping arms 3 are respectively rotatably connected to the two sliders 41; the size of the first through groove 403 is adapted to the slider 41.

[0033] Specifically, guide rods 42 are provided on the side wall of any first through groove 403 adjacent to the first groove 401 on the same side. The guide rods 42 are horizontally arranged transversely and are located in the first through groove 403. The guide rods 42 penetrate into the interior of the slider 41 on the same side. The slider 41 slides horizontally on the guide rods 42 to realize the adjustment of the relative position of the clamping arms 3. Wherein, a limit block 43 is further provided at one end of the guide rod 42 penetrating into the interior of the slider 41. A spring 44 sleeved on the guide rod 42 is abutted between the limit block 43 and the inner side wall of the slider 41. When the slider 41 slides horizontally outward on the guide rod 42, the clamping space becomes larger to adapt to the clamping use of electronic devices of different sizes within a reasonable range. At the same time, the slider 41 presses the spring 44; after releasing the slider 41, the elastic force of the spring 44 on the slider 41 enables the clamping arms 3 to generate a clamping force on the clamped electronic devices such as mobile phones. If there is no clamping, the slider 41 slides back to the initial position. Therefore, when it is necessary to clamp an electronic device such as a mobile phone, the mobile phone and other electronic devices can be clamped and fixed in the clamping space in the above manner. During this process, through the sliding of the slider 41, the relative position of the clamping arms 3 can be changed, so as to adapt to the smooth insertion of mobile phones and other electronic devices of different lengths. When taking out the mobile phone and other electronic devices, the slider 41 is reset by the elastic force of the spring 44.

[0034] It should be noted that, in order to make the sliding of the slider 41 more stable, the number of guide rods 42 in any first through groove 403 is not less than two, and the adjacent two guide rods 42 are arranged at intervals, and the number of limit blocks 43 and springs 44 corresponds to the number of guide rods 42 one by one.

[0035] In this embodiment, a rotating mounting portion 411 is provided at one end of any slider 41 close to the first groove 401 on the same side. A first mounting hole for inserting a rotating connecting member such as a rotating shaft is formed in the rotating mounting portion 411. Correspondingly, the clamping arm 3 is connected to the rotating mounting portion 411 on the same side through a rotating connecting member such as a rotating shaft. An installation matching portion 31 is provided at one end of the clamping arm 3 corresponding to the rotating mounting portion 411. A second mounting hole for inserting a rotating connecting member such as a rotating shaft is formed in the installation matching portion 31. A bayonet 310 for the rotating mounting portion 411 to be snapped into is further provided at the central position of the installation matching portion 31. When the rotating mounting portion 411 is snapped into the bayonet 310, the first mounting hole and the second mounting hole are corresponding. By sequentially inserting the rotating shaft into the first mounting hole and the second mounting hole, the clamping arm 3 can be rotatably connected to the slider 41. In order to make the overall structure beautiful, a notch 4011 for accommodating the rotating mounting portion 411 is correspondingly formed on the inner bottom surface of any first groove 401. When the slider 41 is reset, the whole slider 41 is placed in the first through groove 403, the rotating mounting portion 411 is placed in the notch 4011, and the clamping arm 3 is smoothly received in the first groove 401, having a good appearance effect of hidden storage, and can also effectively avoid the risk of collision, with good use safety.

[0036] In this embodiment, the first hook 2 is slid up and down on the convex shell 4 (i.e., in the second groove 402) through a sliding positioning mechanism. Specifically, the sliding positioning mechanism includes a sliding plate 5. A vertical first hollow groove 501 is formed in the middle of the sliding plate 5. Two clamping convex blocks 502 are respectively provided on the vertical groove walls on both sides of the sliding plate 5 located in the first hollow groove 501. A plurality of clamping convex blocks 502 on the same side are arranged at intervals from top to bottom in sequence. The plurality of clamping convex blocks 502 on both sides correspond to each other in pairs to form a plurality of clamping and fixing areas in the first hollow groove 501 of the sliding plate 5. Among them, a convex column 52 is provided on the inner side wall of the second groove 402. The convex column 52 passes through the first hollow groove 501 and is correspondingly clamped in one of the clamping and fixing areas. The sliding plate 5 can slide up and down relative to the convex column 52. A stop block 53 opposite to the sliding plate 5 is provided at one end of the convex column 52 passing through the first hollow groove 501. The convex column 52 plays a role in guiding and limiting the sliding of the sliding plate 5. The function of the stop block 53 is to prevent the sliding plate 5 from detaching from the convex column 52. The stop block 53 and the convex column 52 are fixedly connected by screws, which is convenient for disassembly so as to sleeved the sliding plate 5 on the convex column 52. The overall shape of the stop block 53 and the convex column 52 after connection is in a T shape, which can not only provide space for the sliding of the sliding plate 5 but also limit the sliding of the sliding plate 5. By setting the sliding positioning mechanism, the flexibility of using the first hook 2 is increased, and the position height of the first hook 2 relative to the clamping arm 3 can also be adjusted to meet different clamping height requirements.

[0037] Wherein, a first anti-slip gasket (not shown in the drawings) is further provided on the inner side surface of the first hook 2 to make it more stable when supporting the electronic device. The lower end of the first hook 2 is rotatably connected to the lower end of the sliding plate. The rotation connection manner and structure between the first hook 2 and the sliding plate can refer to the rotation connection manner and structure between the clamping arm 3 and the slider 41, and only the main setting orientation needs to be adjusted. The flipping angles of the two clamping arms 3 and the first hook 2 are both 90°.

[0038] It should be noted that the above structure for realizing the limited-angle rotational connection through the rotating shaft, the rotating mounting portion 411 and the mounting and mating portion 31 is relatively common. In actual application, any suitable rotational connection structure in the prior art can be adopted, as long as it can realize the limited-angle flipping connection. This is only an example in this embodiment and does not constitute a specific limitation; the magnitude of the rotational damping of the clamping arm 3 and the first hook 2 can be designed and selected according to actual requirements.

[0039] Furthermore, in this embodiment, a mounting seat 6 is provided in the middle of the connecting strip 13. A clamping plate 7 for pressing against the backrest of the seat is provided on the mounting seat 6. The clamping plate 7 is located on the side of the second plate body 12 facing away from the first plate body 11. The clamping plate 7 makes a telescopic movement relative to the mounting seat 6. When the base 1 is installed on the backrest of the seat through the card slot 101, the clamping plate 7 gradually approaches the mounting seat 6 and presses against the backrest of the seat. A telescopic driving mechanism is provided on the mounting seat 6. The clamping plate 7 is connected to the telescopic driving mechanism. The telescopic driving mechanism drives the clamping plate 7 to move in a direction approaching or away from the mounting seat 6. When the clamping plate 7 gradually moves in a direction approaching the mounting seat 6, a pressing force will gradually be generated between the clamping plate 7 and the plastic backboard of the seat backrest, so that the base 1 can be stably installed on the plastic backboard of the seat backrest.

[0040] In this embodiment, an avoidance opening 120 corresponding to the clamping plate 7 and accommodating the clamping plate 7 is provided in the middle of the second plate body 12. The avoidance opening 120 is communicated with the card slot 101, which is convenient for the clamping plate 7 to directly contact the plastic backboard of the seat backrest, which not only facilitates the accommodation of the clamping plate 7, but also can save the manufacturing material of the clamping plate 7 and reduce the production cost.

[0041] Specifically, the mounting base 6 has a cavity inside. The telescopic driving mechanism includes a knob 61 and a screw rod 62 disposed inside the mounting base 6. A second hollow groove 601 is formed on the upper side of the mounting base 6. The knob 61 partially extends out of the mounting base 6 through the second hollow groove 601 to facilitate operating and controlling the rotation of the knob 61. The clamping plate 7 is provided with a screw hole column 71 and a guide post 72 extending into the mounting base 6. The opposite side surfaces of the mounting base 6 and the clamping plate 7 are respectively provided with a first through hole 602 for inserting the screw hole column 71 and a second through hole 603 for inserting the guide post 72. There is one screw hole column 71 corresponding to the screw rod 62, and the number of the first through holes 602 is the same as that of the screw hole column 71. One end of the screw rod 62 is fixedly connected to the knob 61, and the other end of the screw rod 62 is threadedly connected to the screw hole column 71. Among them, there are two guide posts 72, and the number of the second through holes 603 is the same as that of the guide posts 72. The two guide posts 72 are correspondingly located on both sides of the screw hole column 71 and both extend into the mounting base 6. The two guide posts 72 move as the clamping plate 7 moves, mainly for guiding and limiting functions. When the screw rod 62 is rotated by rotating the knob 61, the screw rod 62 drives the screw hole column 71 to move. Then, under the guiding and limiting action of the guide posts 72, the clamping plate 7 moves relative to the mounting base 6.

[0042] Specifically, on the opposite side surface of the mounting base 6 inside and opposite to the first through hole 602, there is an annular flange 63 corresponding to the first through hole 602. On the side surface of the knob 61 facing the annular flange 63, there is a receiving groove 610 for receiving the annular flange 63. The knob 61 is rotationally limited and disposed on the annular flange 63 through the receiving groove 610, enabling the knob 61 to rotate stably.

[0043] Further, in this embodiment, on the convex shell 4 at the position between the second groove 402 and the two first grooves 401, there are also respectively provided a third groove 404. Inside each of the two third grooves 404, there is respectively provided a second hook 8 that can be flipped open or retracted relative to the convex shell 4 (i.e., the third groove 404). The flipping directions of the two second hooks 8 are the same as the flipping direction of the first hook 2. Specifically, the second hook 8 is rotatably connected inside the third groove 404, and the size of the third groove 404 is adapted to the second hook 8. For example, through holes are correspondingly formed in the lower parts of the two opposite inner side walls of the third groove 404. There are two rotating shafts, and the two rotating shafts are correspondingly disposed on the outer side walls at the lower ends of the second hook 8 for correspondingly inserting into the through holes on the same side, so that the second hook 8 can be flipped open by a certain angle to achieve the hooking function. Among them, the flipping angle of the second hook 8 is smaller than the flipping angle of the first hook 2.

[0044] It should be noted that the manner and structure for realizing the rotational connection of the second hook 8 are also relatively common. In actual applications, any suitable rotational connection structure in the prior art can be adopted, as long as it can achieve a limited-angle flipping connection. Only an example is given in this embodiment, which does not constitute a specific limitation.

[0045] Further, in this embodiment, a fourth groove 701 is provided at a lower position on the surface of the clamping plate 7 facing away from the mounting seat 6. The fourth groove 701 is horizontally arranged, and a convex hull 702 corresponding to the fourth groove 701 is provided at a lower position on the surface of the clamping plate 7 facing the mounting seat 6, which is used to tightly press against the plastic backboard of the seat back.

[0046] Among them, avoiding recesses 102 are provided at the upper ends of the first plate body 11 and the convex shell 4, and the lower end of the mounting seat 6 is placed in the avoiding recess 102. By making reasonable use of the space design, the overall aesthetic effect is ensured.

[0047] 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. The clamping slot is as shown at the installation position indicated by the arrow A in the attached Figure 8 figure. During installation, the second plate body 12 is snapped into the clamping slot, and then is fixed to the upper part of the plastic backboard through the clamping slot 101. Then the first plate body 11 correspondingly fits on the outer surface of the plastic backboard. Then, the position of the clamping plate 7 is adjusted through the knob 61, so that the clamping plate 7 gradually approaches the mounting seat 6 to finally tightly press against the plastic backboard, and then 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.

[0048] After the installation is in place, the electronic device can be clamped through the cooperation of the first hook 2 and the two oppositely arranged clamping arms 3. The first hook 2 and the second hook 8 can also be used to hook some objects. The overall structure design is simple, the installation is convenient, and the use is convenient, effectively meeting the different use requirements of the passengers in the back seat of the car, and the use effect is better.

[0049] In some other embodiments, in order to further increase the installation stability of the base 1, a second anti-slip gasket (not shown in the attached drawings) can also be provided at a position on the first plate body 11 corresponding to the avoiding opening 120, so that the first plate body 11 more stably fits on the outer surface of the plastic backboard. For example, both the first anti-slip gasket (not shown in the attached drawings) and the second anti-slip gasket (not shown in the attached drawings) are made of rubber gaskets.

[0050] It should be understood that those of ordinary skill in the art can make improvements or transformations 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.
