[0020] like Figure 1 and Figure 2The rear tow hook 1 shown includes an outer tow hook plate 11, an inner tow hook plate 12, an outer plate reinforcement 15, and an inner plate reinforcement. The outer tow hook plate 11 includes an outer plate body portion 111 and a first connecting plate portion 113. The inner tow hook plate 12 includes an inner plate body portion 121 and a second connecting plate portion 123. The outer plate body portion 111 and the inner plate body portion 121 are fixedly connected to form a first double-layer plate structure. A tow hook hole 13 is provided at the lower part of the first double-layer plate structure. The first connecting plate portion 113 is used to be fixedly connected to the outer side plate of the rear longitudinal beam of the vehicle, and the second connecting plate portion 123 is used to be fixedly connected to the outer side plate of the rear longitudinal beam of the vehicle. The outer plate reinforcement 15 is fixedly connected to the outer side of the outer tow hook plate 11, forming a first cavity reinforcement structure extending from the upper part of the outer tow hook plate 11 to the lower part of the outer tow hook plate 11. The inner plate reinforcement is fixedly connected to the inner side of the inner tow hook plate 12, forming a second cavity reinforcement structure extending from the upper part of the inner tow hook plate 12 to the lower part of the inner tow hook plate 12.

[0021] By adopting the above technical solution, and by setting the first connecting plate portion 113 and the second connecting plate portion 123, the rear tow hook 1 can be connected to the rear longitudinal beam of the vehicle, meeting the requirement of adding the rear tow hook 1 to the vehicle. By forming the first double-layer plate structure, the first cavity reinforcement structure, and the second cavity reinforcement structure, the overall strength and rigidity of the rear tow hook 1 can be enhanced, which helps to improve the safety of the rear tow hook 1. This rear tow hook 1 is particularly suitable for vehicle hub rotation tests, helping to improve test safety.

[0022] As a specific example, the tow hook hole 13 is formed by a first through hole 112 at the lower part of the outer plate body 111 and a second through hole 122 at the lower part of the inner plate body 121.

[0023] In some embodiments, the first connecting plate portion 113 is located above the outer plate body portion 111, the upper part of the outer plate reinforcing member 15 is fixedly connected to the first connecting plate portion 113, and the lower part of the outer plate reinforcing member 15 is fixedly connected to the outer plate body portion 111. The outer plate reinforcing member 15 can reinforce the first connecting plate portion 113 and the outer plate body portion 111. In specific implementations, the outer plate reinforcing member 15 can be a U-shaped reinforcing member, which facilitates the formation of a first cavity reinforcing structure.

[0024] In some embodiments, the second connecting plate portion 123 extends inwardly from the upper edge of the inner plate body portion 121, and the inner plate reinforcing member is fixedly connected to the inner side of the inner plate body portion 121, with its upper end fixedly connected to the second connecting plate portion 123. The inner plate reinforcing member can strengthen both the second connecting plate portion 123 and the inner plate body portion 121.

[0025] In some embodiments, the lower end of the inner plate reinforcement is located inside the tow hook hole 13, and the lower end of the inner plate reinforcement is provided with a first through hole 191 corresponding to the tow hook hole 13. The inner plate reinforcement can strengthen the tow hook hole area, which helps to improve the structural performance of the tow hook hole area, thereby improving the safety performance of the rear tow hook 1.

[0026] In some embodiments, the inner panel reinforcement includes a first sub-reinforcing member 18 fixedly connected to the upper inner side of the inner panel body portion 121 and a second sub-reinforcing member 19 fixedly connected to the lower inner side of the inner panel body portion 121. The upper end of the second sub-reinforcing member 19 is connected to the lower end of the first sub-reinforcing member 18, and the second sub-reinforcing member 19 is inclined backward from top to bottom relative to the first sub-reinforcing member 18. The provision of the first sub-reinforcing member 18 and the second sub-reinforcing member 19 has two advantages: first, it makes it easier to match the shape of the inner panel reinforcement, and the inclined second sub-reinforcing member 19 bypasses the clearance notch 14 to reinforce the tow hook hole area; second, it can form a multi-cavity reinforcement structure, which can further improve the structural performance of the rear tow hook 1.

[0027] In specific implementation, the second sub-reinforcing member 19 can be a U-shaped reinforcing member, and the second sub-reinforcing member 19 can be a box-shaped structure with an open outer side.

[0028] In some embodiments, a first gasket 16 is fixedly connected to the outer side of the first connecting plate portion 113. The first gasket 16 and the first connecting plate portion 113 form a second double-layer plate structure. The second double-layer plate structure is provided with a first connecting hole for fixed connection with the outer side plate of the rear longitudinal beam of the vehicle.

The first gasket 16 is provided with a second through hole 161 corresponding to the third through hole 114. The third through hole 114 and the corresponding second through hole 161 constitute a first connecting hole. As a preferred embodiment, the first connecting plate portion 113 is provided with a first break 115 in the area between the two third through holes 114. Providing the first break 115 can reduce the matching difficulty between the first connecting plate portion 113 and the rear longitudinal beam of the vehicle.

[0030] In some embodiments, a second gasket 17 is fixedly connected to the lower side of the second connecting plate portion 123. The second gasket 17 and the second connecting plate portion 123 form a third double-layer plate structure. The third double-layer plate structure is provided with a second connecting hole for fixed connection with the bottom plate of the vehicle's rear longitudinal beam. Providing the second gasket 17 can locally strengthen the second connecting plate portion 123 and prevent the second connecting plate portion 123 from deforming due to stress.

[0031] In a specific implementation, the second connecting plate portion 123 is provided with two fourth through holes 124, and each of the two fourth through holes 124 is provided with a second gasket 17. The second gasket 17 is provided with a third through hole 171 corresponding to the fourth through hole 124. The fourth through hole 124 and the corresponding third through hole 171 constitute a second connecting hole. As a preferred embodiment, the second connecting plate portion 123 is provided with a second break 125 in the area between the two fourth through holes 124. Providing the second break 125 can reduce the matching difficulty between the second connecting plate portion 123 and the rear longitudinal beam of the vehicle.

[0032] In some embodiments, the rear of the first double-layer plate structure is provided with a clearance notch 14 for avoiding the vehicle exhaust pipe 3. The clearance notch 14 is used to avoid the vehicle exhaust pipe 3, so that the tow hook hole 13 can be better exposed. In a specific implementation, both the outer plate body portion 111 and the inner plate body portion 121 are vertically arranged, and the position of the tow hook hole 13 is lower than the position of the clearance notch 14.

[0033] In some embodiments, the outer panel body 111 and the inner panel body 121 are welded along their periphery, and plug weld holes 116 are provided on the outer panel body 111 and / or the inner panel body 121. The combination of periphery welding and plug welding ensures a stable connection between the outer panel body 111 and the inner panel body 121. In specific implementations, the plug weld holes 116 can be provided on the outer panel body 111, and the welding method can be carbon dioxide shielded welding. Obviously, the reinforcing members and gaskets can also be fixedly connected by welding.

[0034] In practical implementation, the outer hook plate 11 and the inner hook plate 12 can be sheet metal parts made by blanking and bending; the outer plate reinforcing member 15, the first sub-reinforcing member 18, and the second sub-reinforcing member 19 can be sheet metal parts made by stamping; the first gasket 16 and the second gasket 17 can be sheet metal parts made by blanking. The above technical solution has the advantage of simple manufacturing process.

The first connecting plate part 113 is stacked on the outer side of the outer plate 21 and is fastened to the outer plate 21 by bolt and nut assemblies that cooperate with the first connecting holes and the first mounting holes 23. The second connecting plate part 123 is stacked on the lower side of the bottom plate 22 and is fastened to the bottom plate 22 by bolt and nut assemblies that cooperate with the second connecting holes and the second mounting holes 24.

[0036] In practice, the first mounting hole 23 and the second mounting hole 24 mentioned above can be reserved on the rear longitudinal beam 2, and mounting nuts can be fixed at the first mounting hole 23 and the second mounting hole 24.

[0037] When conducting the wheel rotation test, the rear tow hook 1 can be installed on the rear longitudinal beam 2. The clearance notch 14 of the rear tow hook 1 avoids the exhaust pipe 3. After the rear bumper 4 is installed on the vehicle, the tow hook hole 13 of the rear tow hook 1 is below the rear bumper 4 and is fully exposed.
