Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a trailer hitch mounting structure and vehicle. Background Technology

[0002] Currently, tow hooks are automotive auxiliary tools used when a vehicle encounters a breakdown. Their main function is to help a vehicle escape from difficult road conditions or tow other non-powered or damaged vehicles. Existing commercial vehicle tow hooks are typically welded to one side of a longitudinal beam via a bracket. However, this method does not consider the even distribution of force on the tow hook during welding, resulting in excessive bias towards one side of the longitudinal beam. This uneven force at the connection between the tow hook and the longitudinal beam can easily lead to structural damage to one side of the longitudinal beam or damage to the tow hook itself, causing the vehicle to fail to escape. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] like Figures 1 to 3 As shown, this embodiment provides a trailer hitch mounting structure, which includes a connector 1, a first fixing member 2, a connecting sleeve 3, and a second fixing member 4. One side of the connector 1 is connected to the front bumper beam 5 of the vehicle, and the other side is perpendicularly connected to the end of the longitudinal beam 6 of the vehicle. The first fixing member 2 is connected to the inner wall of the longitudinal beam 6. The connecting sleeve 3 is disposed on the first fixing member 2, with one end passing through the connector 1 and perpendicularly connected to it. The connecting sleeve 3 is located at the center of the cross-section of the longitudinal beam 6. The second fixing member 4 encloses the connecting sleeve 3 and is connected to both the first fixing member 2 and the connecting sleeve 3.

[0031] The trailer hook installation structure of this utility model connects the first fixing member 2 to the inner wall of the longitudinal beam 6. One end of the connecting sleeve 3 is perpendicularly connected to the connecting member 1 and located at the center of the longitudinal beam 6 cross-section. This arrangement ensures that the connecting sleeve 3 is at the center of the longitudinal beam 6 cross-section, thus ensuring uniform stress at the connection between the connecting sleeve 3 and the longitudinal beam 6 during operation. This avoids the problem in the prior art where the connecting sleeve 3 is biased to one side of the longitudinal beam 6, which could easily lead to structural damage to the longitudinal beam 6 or the trailer hook. Simultaneously, the second fixing member 4 wraps around the connecting sleeve 3 and is connected to both the first fixing member 2 and the connecting sleeve 3. This improves the connection strength between the connecting sleeve 3 and the longitudinal beam 6, thereby achieving the goal of improving vehicle off-road capability.

[0032] In some embodiments, as Figure 1 and Figure 2As shown, the first fixing member 2 includes a fixing plate 21 and a fixing protrusion 22 connected to each other. The fixing plate 21 is connected to the inner wall of the longitudinal beam 6. This arrangement increases the contact area between the fixing plate 21 and the inner wall of the longitudinal beam 6, thereby improving the connection strength between the first fixing member 2 and the inner wall of the longitudinal beam 6. Simultaneously, a connecting sleeve 3 is mounted on and connected to the fixing protrusion 22. This arrangement facilitates the fixing of the connecting sleeve 3, thereby improving the connection strength between the connecting sleeve 3 and the first fixing member 2. The second fixing member 4 is connected to the fixing protrusion 22.

[0033] Specifically, such as Figure 3 As shown, the fixing protrusion 22 has a mounting groove 221. The mounting groove 221 extends along the axial direction of the connecting sleeve 3 and passes through the fixing protrusion 22, placing the connecting sleeve 3 within the mounting groove 221. This arrangement facilitates the placement of the connecting sleeve 3 and ensures a tight fit with the connecting sleeve 3, making welding and fixing easier.

[0034] In this embodiment, the shape of the mounting groove 221 includes, but is not limited to, an arc shape. This design allows it to match the shape of the outer wall of the connecting sleeve 3, thereby increasing the contact area with the connecting sleeve 3 and improving the connection strength.

[0035] like Figure 1 and Figure 2 As shown, the second fastener 4 has multiple plug welding holes 41. These plug welding holes 41 are spaced apart along the axial direction of the connecting sleeve 3. The second fastener 4 and the connecting sleeve 3 can be welded together through these plug welding holes, thereby securing the second fastener 4 and the connecting sleeve 3.

[0036] Furthermore, the second fixing member 4 includes a first fixing plate 42, a second fixing plate 43, and a third fixing plate 44. The two ends of the second fixing plate 43 are connected to the first fixing plate 42 and the third fixing plate 44 respectively. The second fixing plate 43 wraps around and is connected to the connecting sleeve 3. Both the first fixing plate 42 and the third fixing plate 44 are connected to the first fixing member 2. With this configuration, the connection points between the second fixing plate 43 and the first fixing plate 42 and the third fixing plate 44 each have plug weld holes 41, thus further improving the welding strength between the second fixing member 4 and the connecting sleeve 3.

[0037] In some embodiments, the shape of the second fixing plate 43 includes, but is not limited to, an arc shape, and it fits against the outer wall of the connecting sleeve 3. This arrangement allows the shape of the second fixing plate 43 to match the shape of the outer wall of the connecting sleeve 3, thereby increasing the contact area with the connecting sleeve 3 and improving the connection strength.

[0038] Specifically, the connector 1 has a central hole 11. One end of the connecting sleeve 3 passes through the central hole 11 and is connected to the inner wall of the central hole 11. This facilitates the passage of one end of the connecting sleeve 3 through the connector 1.

[0039] Optionally, connector 1 is a connecting plate with multiple mounting holes for easy connection to the front bumper beam 5.

[0040] Optionally, the front bumper beam 5 has a through hole corresponding to the center hole 11.

[0041] In this embodiment, one of the connecting sleeve 3 and the trailer hook has an internal thread, and the other has an external thread, with the internal and external threads engaging. This arrangement facilitates installation and disassembly.

[0042] Optionally, the longitudinal beam 5 includes an interconnected beam body and a connecting beam, both of which are welded and fixed to the connector 1, thereby forming a trailer hook installation structure with high structural strength.

[0043] This embodiment also provides a vehicle including the trailer hitch mounting structure described above. In the vehicle using this invention, the first fixing member 2 is connected to the inner wall of the longitudinal beam 6, and one end of the connecting sleeve 3 is perpendicularly connected to the connecting member 1 and located at the center of the longitudinal beam 6 cross-section. This arrangement ensures that the connecting sleeve 3 is at the center of the longitudinal beam 6 cross-section, thus ensuring uniform stress at the connection between the connecting sleeve 3 and the longitudinal beam 6 during operation. This avoids the problem in the prior art where the connecting sleeve 3 is biased to one side of the longitudinal beam 6, which could easily lead to structural damage to the longitudinal beam 6 or damage to the trailer hitch. Simultaneously, the second fixing member 4 wraps around the connecting sleeve 3 and is connected to both the first fixing member 2 and the connecting sleeve 3, thereby improving the connection strength between the connecting sleeve 3 and the longitudinal beam 6, and ultimately achieving the vehicle's ability to get out of trouble.
