[0032] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0033] Reference below Figure 1-Figure 9 A trailer hook cover 100 according to an embodiment of the present invention is described, and the trailer hook cover 100 can be applied to a vehicle.

[0034] Combination Figure 1-Figure 9 As shown, the trailer hook cover 100 according to the utility model can mainly include: a first plate body 10 and a second plate body 20, wherein the first plate body 10 is provided with a first clamping portion 11 and a second clamping portion 12, the second clamping portion 12 is spaced above the first clamping portion 11 and is two, the two second clamping portions 12 are spaced from each other in the left-right direction, and the second plate body 20 is provided with a third clamping portion 221 and a fourth clamping portion 231, the first clamping portion 11 and the third clamping portion 221 are clamped together in the up-and-down direction, the second clamping portion 12 and the fourth clamping portion 231 are clamped together in the left-and-right direction, there are two fourth clamping portions 231, and the two fourth clamping portions 231 correspond one-to-one to the two second clamping portions 12.

[0035] Specifically, the vehicle is usually designed with a trailer hook cover 100 as a covering piece for the trailer hook, and when the installation position of the trailer hook cover 100 is at the intersection of two areas, the trailer hook cover 100 is made to include a first plate body 10 and a second plate body 20. In this way, the first plate body 10 and the second plate body 20 can be respectively adapted to the designs of the two areas, thereby ensuring the refinement of the vehicle.

[0036] By providing the first clamping portion 11 on the first plate 10 and the third clamping portion 221 on the second plate 20, the connection between the first plate 10 and the second plate 20 can be achieved through the clamping cooperation between the first clamping portion 11 and the third clamping portion 221. Also, by providing two second clamping portions 12 on the first plate 10 and two fourth clamping portions 231 on the second plate 20, the connection between the first plate 10 and the second plate 20 can be achieved through the one-to-one corresponding clamping cooperation between the two second clamping portions 12 and the two fourth clamping portions 231. In this way, the assembly of the trailer hook cover 100 can be achieved, which not only improves the convenience of assembly, but also allows the first plate 10 and the second plate 20 to be disassembled and replaced separately when one of them is damaged, thereby reducing the maintenance cost of the trailer hook cover 100.

[0037] Furthermore, the two second clamping portions 12 are spaced apart above the first clamping portion 11, and correspondingly, the two fourth clamping portions 231 are spaced apart above the second clamping portion 12, and the first clamping portion 11 and the third clamping portion 221 are clamped together in the up and down directions, and the second clamping portion 12 and the fourth clamping portion 231 are clamped together in the left and right directions. In this way, the structural design of the first plate body 10 and the second plate body 20 can be optimized, and the clamping of the first plate body 10 and the second plate body 20 can be achieved from two directions, so that the distribution of the clamping force between the first plate body 10 and the second plate body 20 is more uniform and reasonable, thereby improving the connection reliability between the first plate body 10 and the second plate body 20, increasing the disassembly strength of the first plate body 10 and the second plate body 20, preventing the first plate body 10 and the second plate body 20 from falling off when the trailer hook cover 100 is removed from the vehicle body, and improving the structural reliability of the trailer hook cover 100.

[0038] Therefore, by arranging the first clamping portion 11 and the second clamping portion 12 on the first plate body 10, the second clamping portion 12 is arranged above the first clamping portion 11 at intervals and there are two of them, the two second clamping portions 12 are spaced apart from each other in the left-right direction, and the third clamping portion 221 and the fourth clamping portion 231 are arranged on the second plate body 20, there are two fourth clamping portions 231, and the two fourth clamping portions 231 correspond to the two second clamping portions 12 one by one, it is only necessary to make the first clamping portion 11 and the third clamping portion 221 clamped and matched in the up and down direction, and the second clamping portion 12 and the fourth clamping portion 231 clamped and matched in the left and right direction, so as to realize the detachable connection between the first plate body 10 and the second plate body 20, which can not only reduce the maintenance cost of the trailer hook cover 100, but also ensure that the trailer hook cover 100 is not prone to the problem of the first plate body 10 and the second plate body 20 being detached after multiple disassemblies, and the structural reliability of the trailer hook cover 100 can be improved.

[0039] Combination Figure 1 , Figure 3 and Fig. 9 As shown, the second plate body 20 can mainly include a first plate portion 21, a second plate portion 22 and a third plate portion 23. The third plate portion 23 is located above the first plate portion 21. The third plate portion 23 and the first plate portion 21 are spaced apart in the front-to-back direction, and the second plate portion 22 is connected between the upper end of the first plate portion 21 and the lower end of the third plate portion 23. In this way, the overall structure of the second plate body 20 can be formed, so that the second plate body 20 has a stepped structure as a whole.

[0040] Specifically, by setting the third clamping portion 221 on the second plate portion 22, and setting the first plate body 10 above the second plate portion 22, and setting the first clamping portion 11 at the lower end of the first plate body 10, when the first plate body 10 is moved from top to bottom close to the second plate portion 22, the clamping fit between the first clamping portion 11 and the third clamping portion 221 can be achieved, and the speed and accuracy of the clamping fit between the first clamping portion 11 and the third clamping portion 221 can be improved.

[0041] Furthermore, the two fourth clamping portions 231 are respectively arranged on the left and right sides of the third plate portion 23, and the first plate body 10 is located on the side of the third plate portion 23 facing the first plate portion 21 in the front-to-back direction. In this way, when the first plate body 10 is moved from top to bottom close to the second plate portion 22, the first plate portion 21 also corresponds to the third plate portion 23 in the front-to-back direction, and the two second clamping portions 12 can also correspond to the two fourth clamping portions 231 for clamping engagement, thereby improving the speed and reliability of the clamping engagement between the second clamping portions 12 and the fourth clamping portions 231.

[0042] In this way, by optimizing the structure of the second plate body 20, when the first plate body 10 is connected to the second plate body 20, the first plate body 10 is not only snap-fitted with the second plate portion 22 in the up and down directions, but also snap-fitted with the third plate portion 23 in the left and right directions, thereby improving the connection stability between the first plate body 10 and the second plate body 20 and improving the disassembly strength between the first plate body 10 and the second plate body 20.

[0043] In some embodiments of the present invention, Figure 1-Figure 9 As shown, the first clamping part 11 is a first clamping buckle, the third clamping part 221 is a first clamping slot, the first clamping buckle and the first clamping slot are clamped together. In addition, the second clamping part 12 is a second clamping slot, the fourth clamping part 231 is a second clamping buckle, the second clamping buckle and the second clamping slot are clamped together.

[0044] Specifically, by setting the first clamping part 11 as the first clamping buckle and the third clamping part 221 as the first clamping slot, it is only necessary to extend the first clamping buckle into the first clamping slot so that the first clamping buckle and the first clamping slot are clamped together, thereby realizing the clamping fit between the first clamping part 11 and the third clamping part 221, thereby not only improving the speed and accuracy of the clamping fit between the first clamping part 11 and the third clamping part 221, but also improving the stability and reliability of the clamping fit between the first clamping part 11 and the third clamping part 221.

[0045] Furthermore, by setting the second clamping portion 12 as a second clamping slot and setting the fourth clamping portion 231 as a second buckle, it is only necessary to extend the second buckle into the second clamping slot so that the second buckle and the second clamping slot are clamped together, thereby realizing the clamping fit between the second clamping portion 12 and the fourth clamping portion 231. This can not only improve the speed and accuracy of the clamping fit between the second clamping portion 12 and the fourth clamping portion 231, but also improve the stability and reliability of the clamping fit between the second clamping portion 12 and the fourth clamping portion 231.

[0046] Furthermore, considering that the first clamping portion 11 and the second clamping portion 12 are both arranged on the first plate body 10, and the third clamping portion 221 and the fourth clamping portion 231 are both arranged on the second plate body 20, by making the structures of the first clamping portion 11 and the second clamping portion 12 different, correspondingly, the structures of the third clamping portion 221 and the fourth clamping portion 231 are different, this can further improve the connection stability between the first plate body 10 and the second plate body 20, and improve the disassembly strength of the trailer hook cover 100.

[0047] Combination Figure 1 as well as Figure 5-Figure 9 As shown, a clamping seat 13 is provided on the first plate body 10, the second clamping portion 12 is provided on the clamping seat 13, and a first supporting rib 232 is provided on the upper end of the third plate portion 23. The first supporting rib 232 is supported and supported against the clamping seat 13 from top to bottom.

[0048] Specifically, a clamping seat 13 is provided on the first plate body 10, and the clamping seat 13 extends not only in the vertical direction but also in the left-right direction, and two clamping seats 13 are provided. By providing the second clamping portion 12 on the clamping seat 13, and providing the first support rib 232 at the upper end of the third plate portion 23, after the second clamping portion 12 and the fourth clamping portion 231 are clamped and matched, the first support rib 232 can be supported up and down with the portion of the clamping seat 13 extending in the left-right direction, which can not only improve the clamping and matching force between the second clamping portion 12 and the fourth clamping portion 231, improve the structural reliability and disassembly strength of the trailer hook cover 100, but also adjust the gap between the first plate body 10 and the second plate portion 22 in the vertical direction, and adjust the gap surface difference of the trailer hook cover 100, so as to improve the refinement of the trailer hook cover 100 and even the vehicle. Optionally, two first support ribs 232 can be provided, and the two first support ribs 232 correspond to the two first clamping seats 13 respectively.

[0049] Furthermore, combined with Figure 1 as well as Figure 5-Figure 9 As shown, two guide protrusions 233 are provided at the upper end of the third plate portion 23, and the two guide protrusions 233 are provided between the two clamping seats 13, and the two guide protrusions 233 are respectively guided and matched with the two clamping seats 13. Specifically, by providing two guide protrusions 233 at the upper end of the third plate portion 23, and the two guide protrusions 233 are arranged at intervals in the left-right direction, when the first plate body 10 is clamped with the second plate body 20 from top to bottom, the two guide protrusions 233 can be located between the two clamping seats 13, and guided and matched with the two clamping seats 13, so that on the one hand, the first plate body 10 can be quickly positioned to the correct assembly position relative to the second plate body 20, thereby improving the assembly efficiency of the trailer hook cover 100, and on the other hand, it can effectively prevent the first plate body 10 from shaking left and right relative to the second plate body 20, thereby ensuring the surface difference of the trailer hook cover 100 in the left-right direction, and improving the refinement of the trailer hook cover 100.

[0050] Combination Figure 1 , Figure 3 as well as Figure 5-Figure 9As shown, a limited flange 131 is provided on one side of the clamping seat 13 away from the first plate body 10 in the front-to-back direction, and the limited flange 131 cooperates with the third plate portion 23 in the front-to-back direction. Specifically, by providing a limited flange 131 on one side of the clamping seat 13 away from the first plate body 10 in the front-to-back direction, after the first plate body 10 is clamped and matched with the second plate body 20, the limited flange 131 can cooperate with the third plate portion 23 in the front-to-back direction, that is, the third plate portion 23 can be limited between the first plate body 10 and the limited flange 131, so that when the trailer hook cover 100 is pried up to remove it from the vehicle body, the limited flange 131 can abut against the third plate portion 23 in the front-to-back direction, thereby avoiding the failure of the clamping between the first plate body 10 and the second plate body 20, further improving the disassembly strength of the trailer hook cover 100, and further improving the structural reliability of the trailer hook cover 100.

[0051] Optionally, a limiting rib 132 may be provided on a side of the limiting flange 131 facing the third plate portion 23 , so that the limiting rib 132 fits the third plate portion 23 .

[0052] Combination Figure 1 , Figure 4 as well as Figure 7-Figure 9 As shown, the lower end of the first plate body 10 is provided with a second support rib 14, and the second support rib 14 is supported and arranged with the second plate portion 22 in an up-and-down manner. Specifically, by providing the second support rib 14 at the lower end of the first plate body 10, the second support rib 14 and the first clamping portion 11 are spaced apart in the left-right direction, so that after the first clamping portion 11 is clamped and matched with the third clamping portion 221, the second support rib 14 and the second plate portion 22 are supported and arranged in an up-and-down manner, which can not only improve the clamping and matching force between the first clamping portion 11 and the third clamping portion 221, improve the structural reliability and disassembly strength of the trailer hook cover 100, but also adjust the gap between the first plate body 10 and the second plate portion 22 in the up-and-down direction, and adjust the gap surface difference of the trailer hook cover 100, so as to improve the refinement of the trailer hook cover 100 and even the vehicle. It should be noted that the height of the second support rib 14 can be adjusted according to the actual loading state.

[0053] Optionally, two second supporting ribs 14 may be provided, and the two second supporting ribs 14 are respectively arranged at intervals on the left and right sides of the first clamping portion 11 .
