[0027] See also Figure 1 and Figure 2The present invention provides a device for simulating the use environment of a trailer hook, comprising a bracket 1 for supporting the rear bumper 3 of a vehicle and a mounting member 2 for connecting the trailer hook 5 to the rear bumper 3. The bracket 1 comprises an adjusting rod 11 and a base 12. The adjusting rod 11 is in the shape of a hollow column as a whole, and the base 12 is in the shape of a hollow prism. The rear bumper 3 is fixedly connected to the end of the adjusting rod 11 away from the base 12 by bonding or welding. Specifically, the adjusting rod 11 comprises an outer rod 111, an inner rod 112, and a connecting assembly 13. The outer rod 111 is sleeved outside the inner rod 112 and fixedly connected to the inner rod 112 via the connecting assembly 13. The inner rod 112 is fixedly connected to the base 12. The height of the rear bumper 3 from the ground can be adjusted by the adjusting rod 11, and the position of the trailer hook 5 relative to the rear bumper 3 can be adjusted by the mounting member 2, thereby ensuring that the trailer hook 5 can be easily installed and removed without affecting the overall appearance of the vehicle. In addition, by verifying the reasonable position of the trailer hook 5 through the trailer hook usage environment simulation device of the present invention, the impact of the trailer hook 5 on the rear space of the vehicle when not in use can be reduced.

[0028] Optionally, the mounting member 2 includes a housing 21 that is fixedly connected to the rear bumper by adhesive bonding, welding, or fastener connection. Specifically, the housing 21 includes a top plate 211 and side plates 212 that together form a receiving cavity for receiving the trailer hook 5.

[0029] In some embodiments, the trailer hook usage environment simulation device of the present invention can also adjust the position of the connector 4 and other peripheral structures of the trailer hook 5, the trailer hook 5, and the rear bumper 3. In this embodiment, the mounting member 2 includes a first mounting plate 23 and a second mounting plate 41. The first mounting plate 23 is fixedly connected to the surface of the top plate 211 near the accommodating cavity, and the second mounting plate 41 is used to be fixedly connected to the connector 4. The first mounting plate 23 and the second mounting plate 41 are fixedly connected to fix the connector 4 to the mounting member 2. Specifically, the first mounting plate 23 and the second mounting plate 41 are fixedly connected by fasteners 24, snap connection, magnetic attraction, or other methods. Optionally, the second mounting plate 41 and the connector 4 are integrally formed or fixedly connected by adhesive bonding or other methods.

[0030] In one example, the first mounting plate 23 and the second mounting plate 41 are fixedly connected by fasteners 24. At least one of the first mounting plate 23 and the second mounting plate 41 has a plurality of connecting holes. The fasteners 24 are passed through different connecting holes on the first mounting plate 23 or the second mounting plate 41 to adjust the position of the connector 4 relative to the mounting member 2, further verifying the spatial position relationship between the trailer hook 5, the connector 4 and the rear bumper 3, avoiding damage to the wiring harness connected to the connector 4 due to extrusion or wear, and improving the rationality of the wiring harness layout.

[0031] Optionally, a first mounting hole and a second mounting hole are respectively formed on the inner rod 112 and the outer rod 111. The first mounting hole and the second mounting hole are connected to each other for passing the connecting assembly 13. Optionally, a plurality of first mounting holes and second mounting holes are arranged along the axial direction of the adjustment rod 11, and the connecting assembly 13 is sequentially inserted into different first mounting holes and the second mounting holes corresponding to the first mounting holes to adjust the relative position of the outer rod 111 and the inner rod 112, thereby adjusting the height of the rear bumper 3 relative to the ground.

[0032] See also Figure 3 In one example, the connecting assembly 13 includes a nut 131 and a bolt 132. The nut 131 is fixed to the inner wall of the inner sleeve rod 112 near the first mounting hole by welding, riveting, etc. The bolt 132 cooperates with the nut 131 to fix the outer sleeve rod 111 to the inner sleeve rod 112.

[0033] See also Figure 4 In another example, the connecting assembly 13 includes an elastic member (not shown) and a stop ball 133. The elastic member is at least partially in the shape of a curved plate and is made of an elastic material such as metal or plastic. The opposite ends of the elastic member are fixedly connected to the inner wall of the inner rod 112 and the stop ball 133, respectively, by bonding or welding. The stop ball 133 at least partially passes through a first mounting hole and a second mounting hole corresponding to the first mounting hole. The stop ball 133 selectively engages with the adjustment rod 11 through the elastic member to limit the relative position of the outer rod 111 and the inner rod 112. Specifically, the stop ball 133 applies pressure to the elastic member. The curved plate structure bends the elastic member, accumulating elastic potential energy and providing an outward-pushing force for the stop ball 133. To adjust the relative position of the outer rod 111 and the inner rod 112, the stop ball 133 is pressed into the inner rod 112, moving the outer rod 111 and thereby adjusting the length of the adjustment rod 11.

The first slide rail 221 and the second slide rail 222 are used to cooperate with each other to adjust the relative position of the trailer hook 5 or the connector 4 and the rear bumper 3 along the length direction of the slide rail assembly 22.

[0035] Optionally, the first slide rail 221 is cylindrical and has a sliding groove defined along its length. The second slide rail 222 is flat, with a portion of the second slide rail 222 slidably embedded in the sliding groove, and another portion of the second slide rail 222 fixedly connected to the trailer hook 5. There are at least two slide rail assemblies 22. The top plate 211 defines a mounting groove 213. At least two first slide rails 221 are embedded in the mounting groove 213 in parallel with each other. The second slide rails 222 are slidably connected to the mounting member via the first slide rails 221.
