[0043] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] First embodiment

[0045] See also Figure 1 In this embodiment, a tow hook device 10 is provided for installation on a vehicle, specifically, on a frame cross member. The tow hook device 10 can be controlled to extend to a suitable position to avoid scratches and interference between the tow hook device 10 and the vehicle during use. Furthermore, the tow hook device 10 can be easily retracted to a suitable position without affecting the vehicle's appearance.

[0046] It should be noted that when a car breaks down or needs to be towed for other reasons, the tow hook assembly 10 mounted on the front of the car is pulled by a trailer. The tow hook assembly 10 provided in this embodiment can be selectively extended from the vehicle body, that is, extended a sufficient distance from the front of the vehicle to prevent the towing device on the trailer or the tow hook assembly 10 from scratching the car when the trailer is towing the car. Furthermore, the tow hook assembly 10 can be retracted into the vehicle body for storage, ensuring that the tow hook assembly 10 does not affect the appearance of the car.

[0047] Please refer to Figures 1 to 5 The towing hook device 10 includes a mounting assembly 100, a towing hook base 200, and a towing hook structure 300. The mounting assembly 100 is used to be mounted on the vehicle's frame cross member, while the towing hook base 200 and the towing hook structure 300 are mounted on the mounting assembly 100. The mounting assembly 100 provides stable load-bearing support to the towing hook base 200 and the towing hook structure 300, ensuring their stable operation.

[0048] In this embodiment, the hook mount 200 is mounted on a side of the mounting assembly 100 that is away from the frame cross member. The hook mount 200 extends away from the mounting assembly 100. A chute 210 is provided on the hook mount 200, extending along the extension direction of the hook mount 200. Specifically, in this embodiment, the chute 210 is disposed within the hook mount 200, with the axis of the chute 210 coinciding with the axis of the hook mount 200. It should be understood that in other embodiments, the chute 210 may alternatively be disposed parallel to the axis of the hook mount 200. Furthermore, the chute 210 opens away from the frame cross member.

[0049] The hook structure 300 extends into the chute 210 and is slidably connected to the hook base 200. Furthermore, the hook structure 300 can be selectively retained by the hook base 200 to ensure relative positional stability between the hook structure 300 and the hook base 200, thereby ensuring stable towing of the vehicle by the hook assembly 10. In this embodiment, the hook base 200 is provided with a plurality of second positioning holes 220, which are spaced apart on the hook base 200. Furthermore, the hook assembly 10 further includes a fixing member 400, which can pass through the second positioning holes 220 and retain the hook structure 300, ensuring relative positional stability of the hook structure 300 relative to the hook base 200. The plurality of second positioning holes 220 extend through the sidewall of the hook base 200 and communicate with the chute 210, allowing the fixing member 400 to pass through the second positioning holes 220 and retain the hook structure 300.

[0050] Furthermore, in this embodiment, a plurality of second positioning holes 220 are arranged on the hook base 200 to form a plurality of second hole rows (not shown). The arrangement direction of the plurality of second positioning holes 220 in each second hole row is substantially aligned with the extension direction of the hook base 200. This allows the hook structure 300 to be secured by the fixing member 400 by penetrating different second positioning holes 220 in the second hole row as it slides along the chute 210. The plurality of second hole rows are spaced apart so that when the hook structure 300 rotates about its own axis in the chute 210, the fixing member 400 can also be secured by penetrating the second positioning holes 220 in different second hole rows.

[0051] In addition, in this embodiment, the multiple second positioning holes 220 in two adjacent second hole columns are staggered with each other, so that the staggered arrangement of the multiple second positioning holes 220 can avoid excessive impact on the strength of the towing hook seat 200, thereby ensuring that the towing hook seat 200 has sufficient strength.

[0052] Specifically, in this embodiment, the tow hook seat 200 is in the shape of a quadrangular prism, and the slide groove 210 is also roughly in the shape of a quadrangular prism. In other words, the tow hook seat 200 has four side surfaces, each of which is provided with a plurality of second positioning holes 220, and the plurality of second positioning holes 220 on adjacent side surfaces are staggered. Furthermore, in this embodiment, the plurality of second positioning holes 220 located on opposite side surfaces correspond one to one, and the line connecting two corresponding second positioning holes 220 is perpendicular to the axis of the tow hook seat 200. In other words, the plurality of second positioning holes 220 can be considered to be formed by providing second positioning holes 220 on the side surfaces of the tow hook seat 200 perpendicular to the quadrangular prism, and simultaneously penetrating two opposing side walls to form two corresponding second positioning holes 220 on the opposing side walls.

[0053] It should be noted that, in the present embodiment, a plurality of second positioning holes 220 on one side surface can be interconnected to form a waist-shaped hole, so that the fixing member 400 can be inserted into the waist-shaped hole to limit the rotation of the towing hook structure 300 along its own axis without limiting the sliding of the towing hook structure 300 along the slide groove 210. When it is necessary to limit the sliding of the towing hook structure 300 along the slide groove 210, it is only necessary to use another fixing member 400 to pass through the second positioning hole 220 on the other side surface to achieve the clamping of the towing hook structure 300, which can facilitate the adjustment of the position of the towing hook structure 300 relative to the towing hook seat 200.

[0054] It should be understood that in other embodiments, the actual shape of the towing hook seat 200 can be designed based on actual conditions. For example, the towing hook seat 200 can be designed as a cylinder, a pentagonal prism, or a hexagonal prism. In addition, in other embodiments, the second positioning holes 220 can be provided on only two adjacent side surfaces of the towing hook seat 200 in the shape of a quadrangular prism, or on three side surfaces.

[0055] The mounting assembly 100 includes a mounting base 110 and a reinforcement member 120. The mounting base 110 is intended for mounting on a vehicle. Specifically, in this embodiment, the mounting base 110 is welded to a frame rail. The tow hook mount 200 is mounted on the side of the mounting base 110 facing away from the frame rail. The reinforcement member 120 is also mounted on the side of the mounting base 110 facing away from the frame rail and is connected to the tow hook mount 200. The reinforcement member 120 provides stable support for the tow hook mount 200, further ensuring its stability.

[0056] In this embodiment, the reinforcement member 120 has a U-shaped cross-section. The outer bottom of the reinforcement member 120 is designed to fit against the side of the hook base 200. A through-slot 121 is defined in the bottom of the reinforcement member 120. The through-slot 121 penetrates the reinforcement member 120 and allows the hook base 200 to be exposed through the through-slot 121, thereby connecting the through-slot 121 with the second positioning hole 220 and, in turn, with the chute 210. This prevents the reinforcement member 120 from interfering with the securing member 400's insertion into the chute 210 and securing the hook structure 300. Furthermore, in this embodiment, two reinforcement members 120 are provided, one on each opposing side of the hook base 200. This provides stable support for the hook base 200 through the reinforcement members 120, further ensuring the stability of the hook base 200. It should be noted that when a second positioning hole 220 is provided on the side surface of the towing hook seat 200 connected to the reinforcement 120, a through groove 121 needs to be provided on the reinforcement 120; when a second positioning hole 220 is not provided on the side surface of the towing hook seat 200 connected to the reinforcement 120, a through groove 121 does not need to be provided on the reinforcement 120.

[0057] One end of the hook structure 300 extends into the chute 210 and is movably connected to the hook base 200. The hook structure 300 can slide along the chute 210 to adjust the length of the hook structure 300 extending from the chute 210, thereby adjusting the length of the entire hook assembly 10. This allows the hook assembly 10 to extend beyond the vehicle body, facilitating towing and preventing the hook assembly 10 or the trailer from scratching the vehicle body during towing. Furthermore, the hook structure 300 can rotate relative to the hook base 200 about its own axis, adjusting the posture of the hook structure 300. When the hook structure 300 is retracted into the chute 210 and retracted into the vehicle for storage, the hook structure 300 can be rotated to an appropriate posture for easy storage, preventing the hook structure 300 from falling out and causing damage to the hook structure 300.

[0058] The towing hook structure 300 includes a towing hook 320 and an adjustment portion 310. One end of the adjustment portion 310 extends into the chute 210 to achieve a movable connection with the towing hook base 200. Furthermore, the towing hook 320 is pivotally connected to the other end of the adjustment portion 310 and can be flipped relative to the adjustment portion 310 to facilitate position adjustment of the towing hook 320, thereby facilitating connection between the towing hook 320 and the trailer and storage of the towing hook 320.

[0059] It should be noted that when the fixing member 400 passes through the slide groove 210, the fixing member 400 is clamped on the adjustment portion 310 to achieve the clamping of the towing hook structure 300, thereby ensuring that the relative position stability between the adjustment portion 310 and the towing hook seat 200 can be maintained.

[0060] Furthermore, in this embodiment, the adjustment portion 310 is provided with a plurality of first positioning holes 313. When the adjustment portion 310 is inserted into the chute 210 and adjusted to a desired position, the fixing member 400 can pass through the connected first positioning holes 313 and second positioning holes 220, thereby achieving mutual engagement between the adjustment portion 310 and the towing hook seat 200. In this embodiment, the plurality of first positioning holes 313 are also arranged on the adjustment portion 310 to form a plurality of first hole rows (not shown). Furthermore, the arrangement direction of the plurality of first positioning holes 313 in each first hole row is substantially the same as the extension direction of the adjustment portion 310. Furthermore, the arrangement direction of the plurality of first positioning holes 313 in the first hole row is the same as the arrangement direction of the plurality of second positioning holes 220 in the second hole row. This ensures that when the adjustment portion 310 slides along the slide groove 210, the plurality of first positioning holes 313 in the first hole row can sequentially overlap and connect with one of the second positioning holes 220 while moving, thereby facilitating the insertion of the fixing member 400 into the connected first positioning hole 313 and second positioning hole 220 and achieving interlocking between the adjustment portion 310 and the towing hook seat 200. Furthermore, the plurality of first hole rows are spaced apart, and the plurality of first positioning holes 313 in two adjacent first hole rows are staggered. This staggered arrangement of the plurality of first positioning holes 313 prevents excessive impact on the overall strength of the adjustment portion 310, thereby ensuring the strength and stability of the adjustment portion 310.

[0061] It should be noted that, in the present embodiment, the plurality of first positioning holes 313 correspond to the plurality of second positioning holes 220, which is manifested as, when the adjustment portion 310 extends into the chute 210, all the first positioning holes 313 and all the second positioning holes 220 correspond one to one. That is, in the present embodiment, the plurality of first positioning holes 313 penetrate the adjustment portion 310 in the radial direction of the adjustment portion 310, and two adjacent first positioning holes 313 are opened in opposite directions and perpendicular to each other. Specifically, the plurality of first positioning holes 313 are opened in such a manner that the first positioning holes 313 are opened in the radial direction of the adjustment portion 310, the axis of the first positioning hole 313 intersects with the axis of the adjustment portion 310, and the axis of the first positioning hole 313 is perpendicular to the axis of the adjustment portion 310. Furthermore, the first positioning hole 313 extends through the adjustment portion 310, forming first positioning holes 313 on opposite sides of the adjustment portion 310. Furthermore, a second first positioning hole 313 is provided perpendicular to the direction of the previous first positioning hole 313, and the first and second first positioning holes 313 are spaced apart from each other. Multiple first positioning holes 313 are sequentially provided in accordance with the above pattern, thereby forming multiple first positioning holes 313 on the adjustment portion 310. It should be noted that when the adjustment portion 310 extends into the chute 210, the two openings of one first positioning hole 313 can simultaneously correspond to two corresponding second positioning holes 220 on two oppositely disposed sides of the towing hook seat 200. At this point, the fixing member 400 can pass through the first and second positioning holes 313, 220, and simultaneously penetrate the towing hook seat 200 and the adjustment portion 310, thereby ensuring stable engagement of the adjustment portion 310 and the towing hook seat 200.

[0062] It should be noted that in this embodiment, the fixing member 400 is arranged in a manner of a pin 410 and a cotter pin 420. Specifically, the pin 410 passes through the hook seat 200 and the adjustment portion 310, and the cotter pin 420 passes through the pin 410 along its axis to prevent the pin 410 from coming out, thereby ensuring stable engagement between the adjustment portion 310 and the hook seat 200. In addition, the fixing member 400 also includes a locking spring 430, which is sleeved on one end of the larger end of the pin 410. The elastic force of the locking spring 430 forces the cotter pin 420 to abut against the hook seat 200 or the reinforcement member 120, thereby ensuring stable engagement between the pin 410 and the adjustment portion 310 and the hook seat 200 and preventing vibration of the pin 410 that could cause unstable engagement.

[0063] It should be noted that in the initial state, Figure 3The adjusting portion 310 extends into the chute 210 so that all the first positioning holes 313 correspond to all the second positioning holes 220. At this time, the fixing members 400 can be inserted into the corresponding first positioning holes 313 and second positioning holes 220 to ensure the stable clamping of the adjusting portion 310 and the towing hook seat 200. In this embodiment, one fixing member 400 is inserted into each of the two mutually perpendicular first positioning holes 313. When only the length of the adjusting portion 310 extending out of the chute 210 needs to be adjusted, the two fixing members 400 can be removed, and then the adjusting portion 310 can be moved along the axial direction of the chute 210 until the adjusting portion 310 moves to the appropriate position and some of the first positioning holes 313 are connected to some of the second positioning holes 220 respectively. The fixing members 400 can then be inserted into the corresponding first positioning holes 313 and second positioning holes 220. In addition, when it is necessary to adjust the angular posture of the adjusting portion 310, the fixing member 400 is removed and the adjusting portion 310 is rotated until the adjusting portion 310 is rotated to the appropriate position, and when some of the first positioning holes 313 and some of the second positioning holes 220 are correspondingly connected, the fixing member 400 is inserted into the corresponding first positioning holes 313 and second positioning holes 220. It should be noted that since the multiple first positioning holes 313 in the adjacent first hole columns are staggered, and the multiple second positioning holes 220 in the adjacent second hole columns are staggered, after adjusting the angular posture of the adjusting portion 310, the adjusting portion 310 will move a certain distance along the axis of the slide groove 210, such as Figure 5 .

[0064] In this example, see Figure 7 The adjustment portion 310 includes a sliding rod 312 and a connecting portion 311. The sliding rod 312 is in the shape of a cylindrical rod and extends into the interior of the slide groove 210. That is, the sliding rod 312 is slidably connected to the tow hook seat 200, that is, the sliding rod 312 can slide along the slide groove 210 and can also rotate relative to the tow hook seat 200 around its own axis. In addition, the sliding rod 312 can be selectively clamped to the tow hook seat 200 so that the sliding rod 312 maintains a relatively stable position relative to the tow hook seat 200. Specifically, in this embodiment, a plurality of first positioning holes 313 are provided on the sliding rod 312. The connecting portion 311 is U-shaped, and the outer side of the bottom of the connecting portion 311 is connected to the sliding rod 312, and the tow hook 320 is rotatably connected to the open end of the connecting portion 311. In this embodiment, the tow hook 320 is rotatably connected to the inner side of the opening of the connecting portion 311.

[0065] In addition, in this embodiment, the adapter portion 311 can provide a limiting function for the slide rod 312, that is, when the slide rod 312 is retracted into the slide groove 210, the adapter portion 311 can be abutted against the edge of the opening of the slide groove 210, thereby providing a limiting function.

[0066] In this example, see Figure 6 The towing hook 320 includes a connecting portion 321 and two hinged portions 322. The two hinged portions 322 are respectively provided at both ends of the connecting portion 321 and together form an I-shape. One end of the two hinged portions 322 is hinged to the adjusting portion 310. Specifically, one end of the two hinged portions 322 is hinged to the open end of the adapter portion 311, and the two hinged portions 322 are hinged to the inner side of the opening of the adapter portion 311. In addition, the towing hook device 10 also includes a latch. The latch passes through the other ends of the two hinged portions 322 and forms a ring with the connecting portion 321 and the two hinged portions 322. The latch facilitates hooking to a trailer through the ring formed by the latch, the connecting portion 321, and the two hinged portions 322, so that the trailer can tow the vehicle through the towing hook device 10.

[0067] Please refer to Figure 3 and Figure 4 In this embodiment, the rotational connection between the hinge part 322 and the adapter part 311 is connected through a fixing part 400, that is, the rotational connection is achieved through the pin shaft 410, the cotter pin 420 and the locking spring 430. The adapter part 311 and the hinge part 322 connected by the fixing part 400 can make the rotation of the hinge part 322 have damping when the hinge part 322 rotates relative to the adapter part 311, thereby ensuring that the hinge part 322 can stay at any specified position relative to the adapter part 311, thereby ensuring that the angle posture of the towing hook 320 relative to the adjustment part 310 can be adjusted, which is convenient for the storage and accommodation of the towing hook 320.

[0068] In summary, the towing hook device 10 provided in this embodiment can adjust the length of the towing hook 320 extending out of the slide groove 210 by sliding the towing hook 320 along the slide groove 210, and then adjust the length of the rotating part extending out of the car, so that the rotating part can be extended to a sufficient length, so that when towing is carried out through the towing hook structure 300, the rotating part can have a sufficient distance from the car body to avoid scratches and damage to the car body. In addition, after the towing is completed, the towing hook 320 can be moved relative to the slide groove 210 so that the towing hook 320 extends into the interior of the slide groove 210, that is, the distance that the towing hook 320 extends out of the slide groove 210 can be shortened, and the rotating part can be retracted into the interior of the vehicle body. At the same time, the towing hook 320 can be rotated relative to the towing hook seat 200 around its own axis, and at the same time, the rotating part can be flipped relative to the towing hook 320, so that the rotating part can be accommodated at any position inside the vehicle body. That is, the towing hook device 10 can control the extension length so that it can be extended to the appropriate position to avoid the problem of scratching and interference during the use of the towing hook 320, and it is easy to be stored in the appropriate position without affecting the appearance of the car.
