As a further improvement, as shown in FIG10 and FIG13 , the side wall of the adjusting nut 4 is provided with anti-slip stripes arranged along the circumference of the adjusting nut 4 , so that the adjusting nut 4 is not easy to slip, making it easier for the user to rotate the adjusting nut 4 .

As a further improvement, as shown in Figures 10 and 11, a ball head 8 for connecting a magnetic mobile phone clamp is provided at one end of the connecting bracket 6 away from the bracket body 1. The ball head 8 is integrally formed with the connecting bracket 6. The ball head 8 is a standard ball head used in conventional vehicle brackets. It has high versatility and is easy to connect and replace. It can be matched with common magnetic clamps on the market.

As a further improvement, as shown in FIG14 and FIG15 , a fan assembly 14 is connected to the bracket body 1 through a flexible metal tube 13 to further enrich the function of the bracket and provide fan blowing service for rear passengers.

Example 3

An embodiment of the present utility model is shown in Figures 16 to 23 (it should be noted that the numbers in this embodiment only correspond to Figures 16 to 23, and have no corresponding relationship with the drawings in other specifications, and have no corresponding relationship with the components corresponding to the numbers in other embodiments), including a base 1 installed on the back of the seat, and a first hook 2 and a second hook 3 are respectively provided on the base 1, which can be flipped open or folded relative to the base 1. The second hook 3 is slid up and down on the base 1 by a sliding mechanism, and the sliding mechanism is also positioned by a positioning mechanism. The position height of the second hook 3 on the base 1 is adjusted by the sliding mechanism and the positioning mechanism.

In this embodiment, the base 1 includes a front panel 11 and a rear panel 12. The upper ends of the front and rear panels 11, 12 are integrally connected, forming a slot 101 between the front and rear panels 11, with the slot 101 facing downward. A first hook 2 and a second hook 3 are both provided on the front surface of the front panel 11. The front and rear panels 11, 12 have identical shapes, each being a long, spindle-shaped panel. Specifically, the lower edge of the front panel 11 is straight, with its ends curving upward. The upper edge of the front panel 11 is straight, with its ends curving downward. The rear panel 12 is essentially the same as the front panel 11, differing in that a notch 120 is provided in the middle of the rear panel 12. This notch 120 serves as a clearance, facilitating smooth insertion of the rear panel 12 into the slot in the back of the car seat. An anti-skid pad (not shown in the drawings) is provided in the middle of the rear surface of the front side plate 11 . The anti-skid pad (not shown in the drawings) corresponds to the notch 120 . The anti-skid pad (not shown in the drawings) is, for example, a rubber pad.

In this embodiment, a convex housing 6 is provided on the front surface of the front side panel 11. This housing 6 matches the front side panel 11 in shape, namely, it is also spindle-shaped, and its outer surface is a smooth, curved, convex shape. A first groove 601 and a second groove 602 are defined in the convex housing 6. The first groove 601 accommodates the first hook 2, and the second groove 602 accommodates the second hook 3. When the first and second hooks 2 and 3 are folded and stowed, they appear to be hidden within the convex housing 6, effectively preventing collisions and providing enhanced safety.

In this embodiment, the sliding mechanism includes a slide 4 having a vertical hollow groove 401 defined in the middle. The positioning mechanism includes locking protrusions 5. The slide 4 is provided with multiple locking protrusions 5 on the vertical groove walls on either side of the hollow groove 401. The multiple locking protrusions 5 on the same side are spaced sequentially from top to bottom, with each pair of locking protrusions 5 corresponding to each other, forming multiple locking and fixing areas within the hollow groove 401 of the slide 4. A guide post 7 is provided within the second groove 602. The guide post 7 extends through the hollow groove 401 and is positioned in one of the locking and fixing areas, allowing the slide 4 to slide up and down relative to the guide post 7. The rear end of the guide post 7 is fixed to the inner surface of the second groove 602, while the front end of the guide post 7 extends through the hollow groove 401 and is located in front of the slide 4. A stopper 8 is also provided at the front end of the guide post 7, facing the slide 4. The guide post 7 guides and limits the movement of the slide 4, while the stopper 8 prevents the slide 4 from disengaging from the guide post 7. The limit stopper 8 is fastened to the guide post 7 by screws, which is convenient for disassembly, so that the slide plate 4 can be sleeved on the guide post 7. The overall shape of the limit stopper 8 and the guide post 7 after being connected is T-shaped, which can not only provide space for the sliding of the slide plate 4, but also limit the sliding of the slide plate 4 in the upward, downward and forward directions.

For example, two locking protrusions 5 are respectively provided on the vertical groove walls on the left and right sides of the hollow groove 401 on the skateboard 4 to form three locking fixing areas in the hollow groove 401 of the skateboard 4. When the lowest locking fixing area in the hollow groove 401 locks the guide column 7 therein, the skateboard 4 is in the initial position. By pulling down the skateboard 4 with force, the locking fixing area changes, and the skateboard 4 can be moved down to adjust the position height of the skateboard 4. The corresponding multiple locking protrusions on both sides are engaged and engaged with the guide column 7 to achieve stable positioning of the skateboard 4. The position height of the skateboard 4 on the convex shell 6 is different, and accordingly, the position height of the second hook 3 is also different.

In this embodiment, the rotating connecting member is, for example, a rotating shaft. First mounting holes are correspondingly formed at the lower portions of two opposing inner side walls of the first groove 601. Two rotating shafts are provided, one on each outer side wall of the lower end of the first hook 2, for insertion into the first mounting holes on the same side, so that the first hook 2 can be flipped open to the first angle to achieve the hooking function.

The lower end of the slide plate 4 is provided with a first horizontal mounting portion for inserting the rotating shaft, and the lower end of the second hook 3 is provided with a second horizontal mounting portion for inserting the rotating shaft. The middle part of the second mounting portion is provided with a slot for the first mounting portion to be inserted. After the first mounting portion is inserted into the slot, the first mounting portion and the second mounting portion can be rotatably connected by the rotating shaft, so that the second hook 3 can be flipped open to a second angle to realize the hooking function.

It should be noted that the above-mentioned structures of 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 a limited angle rotation connection are both relatively existing. In actual application, any suitable rotation connection structure in the existing technology can be adopted, so long as it can achieve a limited angle flip connection. This embodiment is only an example and does not constitute a specific limitation. The size of the rotation damping of the first hook 2 and the second hook 3 can be designed and selected according to actual requirements.

It is understood that the first angle and the second angle can be the same or different, and the degree of rotation 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 the first angle and the second angle are both 45°, the degree of rotation of the first hook 2 and the second hook 3 are the same. Alternatively, if the first angle is 45° and the second angle is 60°, the degree of rotation of the first hook 2 and the second hook 3 are different. Therefore, the different degree of rotation of the first hook 2 and the second hook 3 can be achieved using corresponding existing structures.

In this embodiment, a limiting protrusion 6011 is provided within the first groove 601. The limiting protrusion 6011 does not protrude from the first groove 601. The first hook 2 has an arcuate retaining arm 21 on the side opposite the limiting protrusion 6011. Two arcuate retaining arms 21 are provided, and the two arcuate retaining arms 21 are correspondingly provided at two opposite edges of the first hook. The edges of the two arcuate retaining arms 21 are each provided with a notch 210 that matches the limiting protrusion 6011. The concave curvature of the notch 210 matches the convex curvature of the limiting protrusion 6011. The provision of the notch 210 can further improve the stability of the hook and effectively prevent items from falling. The provision of the limiting protrusion 6011 facilitates the first hook 2 to be fastened thereto through the notch 210.

Furthermore, a plurality of first grooves 601 are provided, and the plurality of first grooves 601 are arranged side by side and spaced apart along the length direction of the convex shell 6. For example, in this embodiment, three first grooves 601 are provided, and the three first grooves 601 are arranged side by side and spaced apart. A first hook 2 is connected to each first groove 601 via a rotating connecting member, and the number of first hooks 2 corresponds to the number of first grooves 601. To facilitate the operation of flipping and opening the first hook 2, a first recess is provided at the upper edge of each first groove 601, so that a finger can be inserted to pull out the first hook 2.

Furthermore, multiple second grooves 602 are provided, and the multiple second grooves 602 are arranged side by side and spaced apart along the length of the convex shell 6, with each second groove 602 correspondingly located between two adjacent first grooves 601. For example, in this embodiment, there are two second grooves 602, which are arranged side by side and spaced apart, and the two second grooves 602 are alternately distributed with the three first grooves 601. Each second groove 602 is connected to a second hook 3 via a sliding mechanism, and the number of second hooks 3 corresponds to the number of second grooves 602. To facilitate the operation of flipping and opening the second hook 3, a second recess is also provided on the upper edge of each second groove 602, allowing a finger to reach in and pull out the second hook 3.

It should be noted that the weight of the objects that can be hooked by the first hook 2 and the second hook 3 should not be too heavy, and the use effect is better within a reasonable weight range.

Using the seat hook bracket of the present invention, the base 1 is mounted in the slot on the seatback of a Tesla vehicle, for example. The slot is indicated by arrow A in FIG23 . During installation, the rear side panel 12 engages the slot, while the front side panel 11 rests against the outer surface of the seatback. The shapes of the front and rear side panels 11 and 12 precisely match the edge of the slot, and thus the spatial shape of the slot 101 also matches it, ensuring a stable installation of the base 1 on the seatback. The presence of a non-slip pad (not shown) further enhances the stability of the base 1, preventing it from loosening and falling.

Example 4

An embodiment of the present invention is shown in Figures 24 to 31 (it should be noted that the reference numerals in this embodiment only correspond to Figures 16 to 23 and do not correspond to components corresponding to reference numerals in other embodiments). The load-bearing portion includes a base 1 mounted on the seat back. The base 1 includes a first plate 11 and a second plate 12 arranged in parallel. The upper ends of the first plate 11 and the second plate 12 are connected, and a clamping slot 101 is formed between the first plate 11 and the second plate 12. A first hook 2 and two clamping arms 3 are provided on a surface of the first plate 11 facing away from the second plate 12. The two clamping arms 3 are arranged opposite each other, and 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 relative to the first plate 11 to open or retract, and the flipping directions of the two clamping arms 3 are perpendicular to the flipping direction of the first hook 2. When 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.

In this embodiment, the base 1 also includes a connecting strip 13, and the upper ends of the first plate 11 and the second plate 12 are integrally connected by the connecting strip 13. A slot 101 is formed between the first plate 11, the second plate 12, and the connecting strip 13, and the base 1 is fixed to the plastic backboard of the seat back through the slot 101. The first plate 11 and the second plate 12 have the same shape, and the first plate 11 and the second plate 12 are both long, spindle-shaped plates. Specifically, the lower edges of the first plate 11 and the second plate 12 are both straight and their ends are curved upward, and the upper edges of the first plate 11 and the second plate 12 are both straight and their ends are curved downward. The curvature of the connecting strip 13 is the same as that of the upper edges of the first plate 11 and the second plate 12.

Furthermore, in this embodiment, a convex shell 4 is provided on the side of the first plate 11 facing away from the second plate 12 (i.e., the outer surface of the first plate 11). The convex shell 4 matches the shape of the first plate 11, also being spindle-shaped, with a smooth, curved, convex outer surface. The first hook 2 and the two clamping arms 3 are rotatably mounted on the convex shell 4. The convex shell 4 has two corresponding first grooves 401 for accommodating the two clamping arms 3, and a second groove 402 for accommodating the first hook 2. The first groove 401 is sized to match the clamping arms 3, while the second groove 402 is sized to match the first hook 2. Among them, two first through grooves 403 are respectively provided on the convex shell 4, and the two first through grooves 403 are correspondingly located on the side of the two first grooves 401 away from the second groove 402, and the two first through grooves 403 are correspondingly communicated with the two first grooves 401; a horizontal limited sliding slider 41 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.

Specifically, a guide rod 42 is provided on a side wall adjacent to the first groove 401 on the same side of any first through-slot 403. The guide rod 42 is horizontally disposed and located within the first through-slot 403. The guide rod 42 penetrates into the interior of the slider 41 on the same side, and the slider 41 slides horizontally on the guide rod 42 to adjust the relative position of the clamping arm 3. A stop block 43 is provided at one end of the guide rod 42 that penetrates into the slider 41. A spring 44 provided on the guide rod 42 abuts between the stop 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 is enlarged to accommodate electronic devices of different sizes within a reasonable range. At the same time, the slider 41 compresses the spring 44. When the slider 41 is released, the elastic force of the spring 44 on the slider 41 causes the clamping arm 3 to generate a clamping force on the clamped electronic device, such as a mobile phone. If the clamping is not achieved, the slider 41 slides back to its initial position. Therefore, when it is necessary to clamp electronic devices such as mobile phones, the mobile phones and other electronic devices can be clamped in the clamping space in the above manner. During this process, the relative position of the clamping arm 3 can be changed by sliding the slider 41, so that mobile phones and other electronic devices of different lengths can be smoothly clamped in. When taking out the mobile phone and other electronic devices, the slider 41 is reset by the elastic force of the spring 44.

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 no less than two, and there is a gap between two adjacent guide rods 42. The number of limit blocks 43 and springs 44 corresponds to the number of guide rods 42 one by one.

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, and a first mounting hole is provided on the rotating mounting portion 411 for inserting a rotating connecting member such as a rotating shaft. Accordingly, 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, and a mounting fitting portion 31 is provided at the end of the clamping arm 3 corresponding to the rotating mounting portion 411. A second mounting hole is provided on the mounting fitting portion 31 for inserting a rotating connecting member such as a rotating shaft, and a bayonet 310 is also provided at the central position of the mounting fitting portion 31 for the rotating mounting portion 411 to be snapped into. When the rotating mounting portion 411 is snapped into the bayonet 310, the first mounting hole and the second mounting hole correspond. By inserting the rotating shaft into the first mounting hole and the second mounting hole in sequence, the clamping arm 3 can be rotatably connected to the slider 41. In order to make the overall structure beautiful, a corresponding recess 4011 for accommodating the rotating mounting portion 411 is provided on the inner bottom surface of any first groove 401. When the slider 41 is reset, the slider 41 is placed as a whole in the first through groove 403, and the rotating mounting portion 411 is placed in the recess 4011. The clamping arm 3 is smoothly stored in the first groove 401, which has a better hidden storage appearance effect, can effectively avoid collision risks, and is safer to use.

In this embodiment, the first hook 2 is slid up and down on the convex shell 4 (i.e., within the second groove 402) via a sliding positioning mechanism. Specifically, the sliding positioning mechanism includes a slide plate 5, with a first vertical hollow groove 501 defined in the middle thereof. Two retaining protrusions 502 are provided on the vertical groove walls on either side of the first hollow groove 501. Multiple retaining protrusions 502 on the same side are spaced apart from each other from top to bottom, with the multiple retaining protrusions 502 on either side corresponding to each other, thereby forming multiple retaining areas within the first hollow groove 501 of the slide plate 5. A boss 52 is provided on the inner sidewall of the second groove 402. The boss 52 extends through the first hollow groove 501 and is correspondingly retained in one of the retaining areas, allowing the slide plate 5 to slide up and down relative to the boss 52. A stopper 53 is provided at one end of the boss 52 passing through the first hollow groove 501, which is opposite to the slide plate 5. The boss 52 guides and limits the sliding of the slide plate 5, and the stopper 53 prevents the slide plate 5 from separating from the boss 52. The stopper 53 is fastened to the boss 52 by screws, which facilitates disassembly so that the slide plate 5 can be sleeved on the boss 52. The overall shape of the stopper 53 and the boss 52 after connection is T-shaped, which can not only provide space for the sliding of the slide plate 5 but also limit the sliding of the slide plate 5. The provision of a sliding positioning mechanism increases the flexibility of the use of the first hook 2 and can also be used to adjust the position height of the first hook 2 relative to the clamping arm 3 to meet different clamping height requirements.

The inner side of the first hook 2 is also equipped with a first anti-slip pad (not shown in the drawings) to provide greater stability when supporting electronic devices. The lower end of the first hook 2 is pivotally connected to the lower end of the slide. The pivotal connection and structure of the first hook 2 and the slide can be similar to the pivotal connection and structure of the clamping arm 3 and the slider 41, with the main positioning being adjusted. The tilt angle of both clamping arms 3 and the first hook 2 is 90°.

It should be noted that the above-mentioned structure for realizing a limited-angle rotation connection through a rotating shaft, a rotating mounting portion 411 and a mounting matching portion 31 is relatively existing. In actual application, any suitable rotation connection structure in the prior art may be adopted, so long as a flip connection capable of realizing a limited-angle is achieved. This embodiment is only an example and does not constitute a specific limitation. The size of the rotation damping of the clamping arm 3 and the first hook 2 can be designed and selected according to actual requirements.

Furthermore, in this embodiment, a mounting seat 6 is provided in the middle of the connecting strip 13, and a splint 7 for pressing against the back of the seat is provided on the mounting seat 6, and the splint 7 is located on the side of the second plate body 12 facing away from the first plate body 11. The splint 7 performs telescopic movement relative to the mounting seat 6, and when the base 1 is installed on the back of the seat through the slot 101, the splint 7 gradually approaches the mounting seat 6 and presses against the back of the seat. A telescopic driving mechanism is provided on the mounting seat 6, and the splint 7 is connected to the telescopic driving mechanism. The telescopic driving mechanism drives the splint 7 to move toward or away from the mounting seat 6. When the splint 7 gradually moves toward the mounting seat 6, a pressing force is gradually generated between the splint 7 and the plastic back panel of the seat back, thereby enabling the base 1 to be stably installed on the plastic back panel of the seat back.

In this embodiment, an avoidance opening 120 corresponding to the splint 7 and accommodating the splint 7 is opened in the middle of the second plate body 12. The avoidance opening 120 is communicated with the card slot 101, which facilitates the direct contact between the splint 7 and the plastic back panel of the seat back. It is convenient for accommodating the splint 7, and can also save materials for manufacturing the splint 7 and reduce production costs.

Specifically, the mounting seat 6 has a cavity therein, and the telescopic drive mechanism includes a knob 61 and a screw 62 provided in the mounting seat 6. A second hollow slot 601 is provided on the upper side of the mounting seat 6, and the knob 61 partially extends out of the mounting seat 6 through the second hollow slot 601 to facilitate the operation of the control knob 61. A screw hole column 71 and a guide column 72 are provided on the splint 7, which extend into the mounting seat 6. A first through hole 602 for inserting the screw hole column 71 and a second through hole 603 for inserting the guide column 72 are respectively provided on the side surface of the mounting seat 6 opposite to the splint 7. There is one screw hole column 71 and it corresponds to the screw 62. The number of the first through holes 602 is the same as that of the screw hole column 71. One end of the screw 62 is fixedly connected to the knob 61, and the other end of the screw 62 is threadedly connected to the screw hole column 71. There are two guide columns 72, and the number of the second through holes 603 is the same as that of the guide columns 72. The two guide columns 72 are located on both sides of the screw hole column 71 and extend into the mounting base 6. The two guide columns 72 move with the movement of the splint 7 and are mainly used to play a guiding and limiting role. When the screw 62 is rotated by rotating the knob 61, the screw 62 drives the screw hole column 71 to move. Under the guiding and limiting action of the guide column 72, the splint 7 moves relative to the mounting base 6.

Specifically, an annular flange 63 is provided on a side surface of the mounting base 6 opposite the first through hole 602. The annular flange 63 corresponds to the first through hole 602. A receiving groove 610 for receiving the annular flange 63 is provided on a side surface of the knob 61 facing the annular flange 63. The knob 61 is rotationally limited by the receiving groove 610 and is mounted on the annular flange 63, allowing the knob 61 to rotate stably.

Furthermore, in this embodiment, the convex housing 4 further includes a third recess 404 located between the second recess 402 and the two first recesses 401. Each of the two third recesses 404 houses a second hook 8 that can be flipped open or retracted relative to the convex housing 4 (i.e., the third recess 404). The flipping direction of the two second hooks 8 is the same as the flipping direction of the first hook 2. Specifically, the second hook 8 is rotatably connected within the third recess 404, and the dimensions of the third recess 404 are adapted to those of the second hook 8. For example, through-holes are defined on the lower portions of two opposing inner sidewalls of the third recess 404. Two rotating shafts are provided, one on each outer sidewall of the lower end of the second hook 8, for insertion into the through-holes on the same side. This allows the second hook 8 to flip open to a certain angle to achieve a hooking function. The flipping angle of the second hook 8 is smaller than that of the first hook 2.

It should be noted that the method and structure for realizing the rotational connection of the second hook 8 are also relatively existing. In actual application, any suitable rotational connection structure in the prior art can be adopted, so long as it can realize a flip connection with a limited angle. This embodiment is only an example and does not constitute a specific limitation.

Furthermore, in this embodiment, a fourth groove 701 is provided at a lower position on the side surface of the splint 7 facing away from the mounting seat 6. The fourth groove 701 is arranged horizontally, and a convex bump 702 corresponding to the fourth groove 701 is provided at a lower position on the side surface of the splint 7 facing the mounting seat 6, which is used to press tightly against the plastic back panel of the seat back.

Among them, the upper ends of the first plate body 11 and the convex shell 4 are both provided with an avoidance recess 102, and the lower end of the mounting seat 6 is placed in the avoidance recess 102, which rationally utilizes the space design and ensures the overall aesthetic effect.

Using the seat hook bracket of the present invention, the base 1 is adapted to be mounted in the slot of the seat back, for example, in a Tesla vehicle. The slot is indicated by arrow A in FIG31 . During installation, the second plate 12 is inserted into the slot and then secured to the upper portion of the plastic back panel via the slot 101. The first plate 11 then fits against the outer surface of the plastic back panel. The position of the clamping plate 7 is then adjusted using the knob 61, gradually approaching the mounting base 6 until it rests firmly against the plastic back panel, ensuring a stable installation of the base 1. The shapes of the first and second plates 11, 12, and connecting strip 13 precisely match the orientation of the slot edge, thus matching the spatial shape of the slot 101. The inner surfaces of the first and second plates 11, 12, and connecting strip 13 are all smooth, facilitating smooth insertion of the slot 101.

After installation, the electronic device can be clamped by using 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 structural design is simple, easy to install and use, effectively meeting the different usage needs of passengers in the back seat of the car, and the use effect is better.

In other embodiments, to further enhance the installation stability of the base 1, a second anti-slip pad (not shown in the drawings) may be provided on the first plate 11 at a position corresponding to the avoidance opening 120 to ensure a more stable fit of the first plate 11 against the outer surface of the plastic backing. For example, both the first anti-slip pad (not shown in the drawings) and the second anti-slip pad (not shown in the drawings) may be rubber pads.

Example 5

An embodiment of the present utility model is shown in Figures 32 to 38 (it should be noted that the numbers in this embodiment only correspond to Figures 32 to 38, and have no corresponding relationship with the figures in other specifications, and have no corresponding relationship with the components corresponding to the numbers in other embodiments), the load-bearing part includes a base 1 installed on the back of the seat, the base 1 is provided with a hook 2, the lower end of the base 1 has a slot 101, the upper end of the base 1 is provided with a mounting seat 3, the mounting seat 3 is provided with a splint 4, the splint 4 performs telescopic movement relative to the mounting seat 3, and when the base 1 is installed on the back of the seat through the slot 101, the splint 4 gradually approaches the mounting seat 3 and presses against the back of the seat.

In this embodiment, the base 1 comprises a first plate 11, a second plate 12, and a connecting bar 13. The first and second plates 11, 12 are parallel to each other and connected at their upper ends by the connecting bar 13. A slot 101 is formed between the first, second, and connecting bars 13, and the base 1 is secured to the plastic back panel of the seat via the slot 101. Specifically, the first, second, and connecting bars 13 are integrally connected. The first and second plates 11, 12 are identical in shape, each being a long, spindle-shaped plate. The lower edges of the first and second plates 11, 12 are both straight, with their ends curving upward. The upper edges of the first and second plates 11, 12 are both straight, with their ends curving downward. The curvature of the connecting bar 13 is the same as that of the upper edges of the first and second plates 11, 12. The mounting seat 3 is arranged in the middle of the connecting strip 13, and an avoidance opening 120 corresponding to the splint 4 and accommodating the splint 4 is opened 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 splint 4 to directly contact the plastic back panel of the seat back, which is convenient for accommodating the splint 4 and can also save materials for manufacturing the splint 4 and reduce production costs.

It should be noted that the length of the clamping plate 4 is based on the length that can contact and tightly abut the plastic back plate of the seat back.

In this embodiment, the mounting base 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 12 facing away from the first plate 11. The mounting base 3 is provided with a telescopic drive mechanism, and the clamping plate 4 is connected to the telescopic drive mechanism. The telescopic drive mechanism drives the clamping plate 4 to move toward or away from the mounting base 3. As the clamping plate 4 gradually moves toward the mounting base 3, it gradually generates a pressing force between the clamping plate 4 and the plastic backboard of the seat back, thereby stably mounting the base 1 on the plastic backboard of the seat back.

Specifically, the mounting base 3 has a cavity therein, and the telescopic drive mechanism includes a knob 51 and a screw 52 provided in the mounting base 3. A through slot 301 is provided on the upper side of the mounting base 3, and the knob 51 partially extends out of the mounting base 3 through the through slot 301 to facilitate the operation of the control knob 51 to rotate. The splint 4 is provided with a screw hole column 41 and a guide column 42 extending into the mounting base 3. The surface of the mounting base 3 opposite to the splint 4 is respectively provided with a first through hole 302 for inserting the screw hole column 41, and a second through hole 303 for inserting the guide column 42. There is one screw hole column 41 and it corresponds to the screw 52. The number of the first through holes 302 is the same as that of the screw hole column 41. One end of the screw 52 is fixedly connected to the knob 51, and the other end of the screw 52 is threadedly connected to the screw hole column 41. There are two guide columns 42, and the number of the second through holes 303 is the same as that of the guide columns 42. The two guide columns 42 are located on both sides of the screw hole column 41 and extend into the mounting base 3. The two guide columns 42 move with the movement of the splint 4 and are mainly used to play a guiding and limiting role. When the screw 52 is rotated by rotating the knob 51, the screw 52 drives the screw hole column 41 to move. Under the guiding and limiting action of the guide column 42, the splint 4 moves relative to the mounting base 3.

Specifically, an annular flange 31 is provided on a surface of the mounting base 3 opposite the first through hole 302. The annular flange 31 corresponds to the first through hole 302. A first groove 510 is provided on a surface of the knob 51 facing the annular flange 31 to accommodate the annular flange 31. The knob 51 is rotationally limited by the first groove 510 on the annular flange 31, allowing the knob 51 to rotate stably.

In this embodiment, a second groove 401 is provided at a lower position on the side surface of the splint 4 facing away from the mounting seat 3. The second groove 401 is arranged horizontally. A convex bump 402 corresponding to the second groove 401 is provided at a lower position on the side surface of the splint 4 facing the mounting seat 3, which is used to press tightly against the plastic back panel of the seat back.

In this embodiment, a convex shell 6 is provided on the side of the first plate 11 facing away from the second plate 12. The convex shell 6 matches the shape of the first plate 11, namely, it is also spindle-shaped, and the outer surface of the convex shell 6 is a smooth, curved, convex shape. The convex shell 6 is provided with a plurality of third grooves 601, arranged side by side and spaced apart. Each third groove 601 is provided with a hook 2, which can be flipped open or retracted, creating a hidden storage effect on the convex shell 6. It also effectively prevents collision hazards and provides improved safety.

For example, if three third grooves 601 are provided, then correspondingly, there are three hooks 2 , wherein the middle hook 2 is slid up and down in the corresponding third groove 601 through a sliding positioning mechanism.

Specifically, the sliding positioning mechanism includes a slide 7, which has a vertical hollow groove 701 in the middle. Two latching protrusions 702 are provided on the vertical groove walls on either side of the slide 7 within the hollow groove 701. Multiple latching protrusions 702 on the same side are spaced apart from top to bottom, and the multiple latching protrusions 702 on both sides correspond to each other, forming multiple latching and fixing areas within the hollow groove 701 of the slide 7. A boss 72 is provided on the inner sidewall of the middle third groove 601. The boss 72 passes through the hollow groove 701 and is correspondingly latched in one of the latching and fixing areas, allowing the slide 7 to slide up and down relative to the boss 72. A stopper 73 is provided at one end of the boss 72 that passes through the hollow groove 701, opposing the slide 7. The boss 72 guides and limits the sliding of the slide 7, and the stopper 73 prevents the slide 7 from separating from the boss 72. The stopper 73 is fastened to the boss 72 via screws, allowing for easy disassembly, allowing the slide 7 to be fitted onto the boss 72. The stopper 73 and boss 72 are connected to form a T-shape, which not only provides space for the slide 7 to slide, but also limits its position. The provision of a sliding positioning mechanism increases the flexibility of the hook 2, meeting the diverse needs of users.

In this embodiment, the lower portions of the two hooks 2, which are not slidably mounted via a sliding positioning mechanism, are both rotatably connected to the corresponding third groove 601 via a rotating shaft. Specifically, taking one of the hooks 2 as an example, first mounting holes 6011 are correspondingly defined at the lower portions of the two opposing inner sidewalls of the third groove 601. Two rotating shafts are provided, one on each outer sidewall of the lower end of the hook 2, for insertion into the first mounting holes 6011 on the same side, thereby enabling the hook 2 to be flipped open to the first angle to achieve the hooking function.

In this embodiment, the lower portion of the middle hook 2, which is slidably mounted via a sliding positioning mechanism, is rotatably connected to the lower portion of the slide 7 via a rotating shaft. Specifically, the lower end of the slide 7 is provided with a first, transverse mounting portion 711 for inserting the rotating shaft, and the lower end of the hook 2 is provided with a second, transverse mounting portion 211 for inserting the rotating shaft. The middle portion of the second mounting portion 211 is provided with a snap-in notch 2110 for the first mounting portion 711 to engage. Once the first mounting portion 711 engages the snap-in notch 2110, the first mounting portion 711 and the second mounting portion 211 can be rotatably connected via the rotating shaft, allowing the hook 2 to flip open to a second angle to achieve a hooking function.

It should be noted that the above-mentioned structures for achieving limited-angle 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 existing. In actual application, any suitable rotation connection structure in the existing technology can be adopted, so long as the flip connection that can achieve limited angle is achieved. This embodiment is only an example and does not constitute a specific limitation. The size of the rotation damping of each hook 2 can be designed and selected according to actual requirements.

It is understandable 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.

Furthermore, the upper ends of the first plate 11 and the convex shell 6 are both provided with an avoidance recess 90 , and the lower end of the mounting seat 3 is placed in the avoidance recess 90 , which rationally utilizes the space design and ensures the overall aesthetic effect.

Using the seat hook bracket of the present invention, the base 1 is adapted to be mounted in the slot of the seat back, for example, in a Tesla vehicle. The slot is indicated by arrow A in FIG38 . During installation, the second plate 12 is inserted into the slot and then secured to the upper portion of the plastic back panel via the slot 101. The first plate 11 then conforms to the outer surface of the plastic back panel. The position of the clamping plate 4 is then adjusted using the knob 51, gradually approaching the mounting base 3 until it rests firmly against the plastic back panel, ensuring a stable installation of the base 1. The shapes of the first and second plates 11, 12, and connecting strip 13 precisely match the orientation of the slot edge, thus aligning the spatial shape of the slot 101. The inner surfaces of the first and second plates 11, 12, and connecting strip 13 are all smooth, facilitating smooth insertion of the slot 101.

In other embodiments, in order to further increase the installation stability of the base 1, an anti-slip gasket (not shown in the drawings) can be provided at a position on the first plate 11 corresponding to the avoidance opening 120 to enable the first plate 11 to fit more stably on the outer surface of the plastic back panel.

It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
