To meet aesthetic requirements, these mounting hooks are generally shorter. This often results in the child seat not being securely fastened, resulting in a loose connection between the mounting hooks, posing a potential safety risk to child passengers. Utility Model Content

[0003] Based on this, it is necessary to provide a hook structure and a safety seat installation system to solve the problems that the installation hooks on the existing vehicle body are not aesthetically pleasing and are prone to loose connections.

[0004] The hook structure provided in the present application includes a connecting bracket, a hook and a limit adjustment piece. The hook structure can be fixedly connected to the vehicle body through the connecting bracket. The limit adjustment piece is installed on the connecting bracket. One end of the hook is movably limited and connected to the limit adjustment piece, and the other end extends out of the end of the connecting bracket along a preset direction. The hook extending out of the end of the connecting bracket is used to clamp the safety seat, and the limit adjustment piece can adjust the length of the hook extending out of the end of the connecting bracket.

[0005] In one embodiment, the limit adjustment member includes a limit card plate and a limit bolt. The limit card plate is installed on the connecting bracket. One of the limit card plate and the hook is provided with a plurality of clamping grooves arranged at intervals along a preset direction, and the other is provided with mounting holes corresponding to the clamping grooves. The limit bolt can be passed through the mounting hole and inserted into the corresponding clamping slot, so that the hook can be limitedly connected to the preset position of the limit card plate by the limit bolt.

[0006] In one embodiment, one or both of the inner wall of the mounting hole and the inner wall of the clamping groove are threadedly connected to the outer side wall of the limiting bolt.

[0007] In one embodiment, there are multiple mounting holes, and the multiple mounting holes are spaced apart along a preset direction.

[0008] In one embodiment, the limiting clamping plate includes a first limiting plate and a second limiting plate, and the first limiting plate and the second limiting plate cooperate to form a limiting through hole extending along a preset direction. The hook is movably passed through the limiting through hole along the preset direction. The mounting hole is provided on the first limiting plate and connected to the limiting through hole. A plurality of snap-fit ​​grooves are respectively provided on the snap-fit ​​hook. The limiting bolt can be passed through the mounting hole and inserted into the corresponding snap-fit ​​groove in the limiting through hole.

[0009] In one embodiment, the first limiting plate and the second limiting plate are sheet metal parts, the first limiting plate is bent to form a first fixing groove with an opening toward the second limiting plate, and the second limiting plate is bent to form a second fixing groove with an opening toward the first limiting plate. The first fixing groove and the second fixing groove are arranged opposite to each other and surrounded to form a limiting through hole.

DETAILED DESCRIPTION

[0021] With the widespread adoption of vehicles, the use of child seats is also increasing. Child seats are primarily secured to the back seat of a car using mounting hooks on the vehicle body. To meet aesthetic requirements, these mounting hooks are generally shorter. This often results in the child seat not being securely fastened, resulting in a loose connection between the mounting hooks, posing a potential safety risk to child passengers.

[0022] See also Figure 1-Figure 3 In order to solve the problems that the existing installation hooks on the vehicle body are not aesthetically pleasing and the installation hooks are easily connected, the present application provides a hook structure and a safety seat installation system. The hook structure includes a connecting bracket 100, a hook 200 and a limit adjustment member 300. The hook structure is used to fix the connection to the vehicle body through the connecting bracket 100 (including but not limited to welding, clamping or fastener connection and other connection methods). The limit adjustment member 300 is installed on the connecting bracket 100. One end of the hook 200 is movably limited and connected to the limit adjustment member 300, and the other end extends out of the end of the connecting bracket 100 along a preset direction. The hook 200 extending out of the end of the connecting bracket 100 is used to clamp the safety seat (not shown in the figure), and the limit adjustment member 300 can adjust the length of the hook 200 extending out of the end of the connecting bracket 100.

[0023] With such an arrangement, on the one hand, when the safety seat is not installed, the length of the hook 200 extending from the end of the connecting bracket 100 in a preset direction can be shortened, and the position of the hook 200 can be fixed by the limit adjustment member 300, so that when the safety seat is not installed, the exposed length of the hook 200 is shorter, which is beneficial to improving the aesthetics of the entire hook structure. In addition, it can also prevent the hook 200 from extending too far from the connecting bracket 100 and affecting the passenger's riding experience, that is, it can also improve the riding comfort of the rear seats.

[0024] On the other hand, when a safety seat needs to be installed, the length of the hook 200 extending from the end of the connecting bracket 100 can be extended along a preset direction, and the position of the hook 200 can be fixed by the limit adjustment member 300, so that when the safety seat is installed, the exposed length of the hook 200 is longer, which is conducive to the hook 200 being connected to the safety seat and preventing the safety seat from being loosely connected.

[0025] Specifically, the cross section of the connecting bracket 100 is approximately U-shaped, so as to facilitate welding or clamping of the connecting bracket 100 and the vehicle body.

[0026] In one embodiment, if Figure 1-Figure 3 As shown, the limit adjustment member 300 includes a limit card plate 320 and a limit bolt 310. The limit card plate 320 is installed on the connecting bracket 100. One of the limit card plate 320 and the hook 200 is provided with a plurality of clamping grooves 210 arranged at intervals along a preset direction, and the other is provided with a mounting hole 3211 corresponding to the clamping groove 210. The limit bolt 310 can be passed through the mounting hole 3211 and inserted into the corresponding clamping groove 210, so that the hook 200 can be limited and connected to the preset position of the limit card plate 320 through the limit bolt 310.

[0027] With such a setting, the relative position of the hook 200 and the limiting clamping plate 320 can be adjusted by clamping the limiting bolt 310 in different clamping grooves 210. In addition, the installation and disassembly of the limiting bolt 310 are relatively simple, which is conducive to the rapid adjustment of the limiting adjustment member 300 and the hook 200.

[0028] However, the present invention is not limited thereto. In other embodiments, the limit adjustment member 300 may also be a telescopic rod (not shown), one end of the telescopic rod being fixedly connected to the connecting bracket 100, and the other end being fixedly connected to the hook 200. By adjusting the telescopic length of the telescopic rod itself, the length of the hook 200 extending out of the end of the connecting bracket 100 can be adjusted.

[0029] Such an arrangement can also realize rapid adjustment of the limit adjustment member 300 and the hook 200 .

[0030] In one embodiment, only one mounting hole 3211 is required to achieve adjustment of the length of the hook 200 extending from the end of the connecting bracket 100 .

[0031] However, in order to increase the adjustment stroke, in other embodiments, a plurality of mounting holes 3211 spaced apart along a preset direction may be provided.

[0032] Furthermore, in one embodiment, Figure 1-Figure 3As shown, one or both of the inner wall of the mounting hole 3211 and the inner wall of the clamping groove 210 are threadedly connected to the outer wall of the limiting bolt 310 .

[0033] In this way, the limiting bolt 310 can be easily removed or installed by screwing the limiting bolt 310 , thereby reducing the difficulty of adjusting the limiting adjustment member 300 .

[0034] However, the present invention is not limited thereto. In other embodiments, the limiting bolt 310 may pass through the limiting clamping plate 320 and the hook 200 , and the limiting bolt 310 may be assembled, fixed, and disassembled by the cooperation of a nut and a screw.

[0035] In one embodiment, if Figure 1-Figure 3 As shown, the limiting clamping plate 320 includes a first limiting plate 321 and a second limiting plate 322. The first limiting plate 321 and the second limiting plate 322 cooperate to form a limiting through-hole 323 extending in a predetermined direction. The hook 200 is movably disposed through the limiting through-hole 323 along the predetermined direction and movably cooperates with the limiting through-hole 323 along the predetermined direction. A mounting hole 3211 is provided on the first limiting plate 321 and communicates with the limiting through-hole 323. A plurality of engaging grooves 210 are provided on the hook 200. The limiting bolts 310 can be disposed through the mounting holes 3211 and inserted into corresponding engaging grooves 210 within the limiting through-hole 323.

[0036] Such an arrangement reduces the difficulty of assembling the limiting clamping plate 320 and the hook 200 .

[0037] In one embodiment, the cross section of the engaging groove 210 is U-shaped, and the engaging groove 210 passes through the hook 200 along a direction perpendicular to the predetermined direction.

[0038] With such a configuration, the engaging groove 210 can be processed on the engaging hook 200 by cutting, thereby facilitating reducing the difficulty of processing the engaging groove 210 .

[0039] However, the present invention is not limited thereto. In other embodiments, the engaging slot 210 may also be in the shape of a hole.

[0040] In one embodiment, if Figure 1-Figure 3 As shown, there are two limiting through holes 323 , and the two limiting through holes 323 are arranged in parallel. The hook 200 is U-shaped, and the two ends of the hook 200 are respectively passed through the two limiting through holes 323 .

[0041] Such a configuration is beneficial to improving the installation stability of the hook 200 and the limiting card plate 320.

[0042] But not limited to this, in other embodiments, the number of the limiting through holes 323 can also be one or three, etc., which are not listed one by one again. For example, when the number of the limiting through hole 323 is one, the hook 200 can be approximately Y-shaped.

[0043] Furthermore, in one embodiment, the first limiting plate 321 and the second limiting plate 322 are detachably connected via fasteners or are snap-fitted via latches.

[0044] This facilitates assembly and disassembly between the first limiting plate 321 and the second limiting plate 322 .

[0045] However, the present invention is not limited thereto. In other embodiments, the first limiting plate 321 and the second limiting plate 322 may be connected by welding, bonding or other connection methods, which are not listed here.

[0046] Furthermore, in one embodiment, Figure 1-Figure 3 As shown, the first limiting plate 321 and the second limiting plate 322 are sheet metal parts. The first limiting plate 321 is bent to form a first fixing groove 3212 with an opening toward the second limiting plate 322. The second limiting plate 322 is bent to form a second fixing groove 3221 with an opening toward the first limiting plate 321. The first fixing groove 3212 and the second fixing groove 3221 are arranged opposite to each other and surround each other to form a limiting through hole 323.

[0047] With such a configuration, the limiting through hole 323 is processed by bending and forming, so that the thickness of the first limiting plate 321 and the second limiting plate 322 can be made relatively thin. On the one hand, it is conducive to the lightweight of the limiting card 320, and on the other hand, it is also conducive to reducing the processing difficulty of the limiting through hole 323.

[0048] However, the present invention is not limited thereto. In other embodiments, the first fixing groove 3212 and the second fixing groove 3221 may also be formed by turning. In this case, the required thickness of the first limiting plate 321 and the second limiting plate 322 is larger.

[0049] Furthermore, in one embodiment, if Figure 1 and Figure 2 As shown, the connecting bracket 100 is provided with a groove 110 , and the portion of the second limiting plate 322 bent away from the first limiting plate 321 is arranged in the groove 110 to reduce the height of the limiting card plate 320 protruding from the surface of the connecting bracket 100 .

[0050] The present application also provides a safety seat installation system, which includes the hook structure described in any one of the above embodiments.
