[0031] This application provides a tow hook assembly and a vehicle, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0032] To address the technical problem of insufficient load-bearing capacity of tow hooks on vehicle bodies in existing technologies, one embodiment of this application provides a tow hook assembly. This tow hook assembly has a first direction and a second direction. When the tow hook assembly is installed on the vehicle body, the first direction is parallel to the height direction of the vehicle body, and the second direction is parallel to the length direction of the vehicle body. The tow hook assembly includes a mounting member for connecting to the vehicle body. The mounting member has a first mounting cavity inside, with mounting walls on both sides in the first direction and support walls on both sides in the second direction. The tow hook assembly also includes a reinforcing component disposed in the first mounting cavity, abutting against the mounting walls and the support walls. The tow hook assembly also includes a tow hook member disposed on the mounting member and connected to the reinforcing component. This will be described in detail below.

[0033] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an embodiment of the tow hook assembly of this application.

[0034] In one embodiment, a tractor unit is connected to a towable caravan via a tow hook assembly 10, and the tractor unit tows the towable caravan via the tow hook assembly 10. The vehicle in this embodiment can be either a tractor unit or a towable caravan. The following description uses a tractor unit as an example only for illustrative purposes and is not intended to limit the scope of the application. Specifically, the vehicle includes a body and a tow hook assembly 10, which is disposed on the body and used to connect to the towable caravan.

[0035] The following describes the tow hook assembly 10 according to an embodiment of this application.

[0036] Please refer to the following: Figure 2 , Figure 2 yes Figure 1 The diagram shows an exploded view of the tow hook assembly.

[0037] In one embodiment, the tow hook assembly 10 has a first direction Z and a second direction X. When the tow hook assembly 10 is installed on the vehicle body, the first direction Z is parallel to the height direction of the vehicle body, and the second direction X is parallel to the length direction of the vehicle body. The tow hook assembly 10 includes a mounting member 11 for connecting to the vehicle body. The mounting member 11 has a first mounting cavity 111 inside, with mounting walls 112 on both sides in the first direction Z and support walls 113 on both sides in the second direction X. The tow hook assembly 10 also includes a reinforcing component 12 disposed in the first mounting cavity 111, abutting against each mounting wall 112 and each support wall 113. The tow hook assembly 10 also includes a tow hook member 13 disposed on the mounting member 11 and connected to the reinforcing component 12.

[0038] In this embodiment, the tow hook 13 is connected to the reinforcing component 12, and the reinforcing component 12 abuts against each mounting wall 112 and each supporting wall 113. That is, the reinforcing component 12 achieves four-sided support in the first mounting cavity 111 inside the mounting component 11. The tow hook 13 increases the overlapping contact surface with the mounting component 11 through the reinforcing component 12. When the load is applied to the tow hook 13, the reinforcing component 12 can provide a more reasonable stress distribution and provide sufficient bending and torsional support to the mounting component 11. This can greatly improve the load-bearing capacity of the tow hook assembly 10 and improve the bending and torsional stiffness of the mounting component 11, which can meet the user's requirements for the RVGW of the towed caravan.

[0039] For example, based on the example of the tow hook assembly 10 being installed on a tractor, the mounting component 11 can specifically be a bumper, such as a rear bumper. Both ends of the mounting component 11 can be connected to the vehicle body via connecting seats 14, and the reinforcing component 12 and the tow hook component 13 can be positioned close to the center of the mounting component 11, without limitation.

[0040] Please refer to the following: Figures 3 to 5 , Figure 3 This is a schematic diagram of an embodiment of the present application in which the reinforcing component and the tow hook are in a connected state. Figure 4 This is an exploded structural diagram of an embodiment of the reinforced component of this application. Figure 5 This is a schematic diagram of an embodiment of the support component of this application being installed on the base.

[0041] In one embodiment, the reinforcing component 12 includes a base 121. The base 121 includes a first base 1211 and second bases 1212 connected to both sides of the first base 1211 in a first direction Z, i.e., the first base 1211 has second bases 1212 connected to both sides of the first base 1211 in the first direction Z. The first base 1211 abuts against a support wall 113 of the mounting member 11, and each second base 1212 abuts against a different mounting wall 112, i.e., one second base 1212 abuts against one mounting wall 112 of the mounting member 11, and the other second base 1212 abuts against another mounting wall 112 of the mounting member 11. The first base 1211 and the second base 1212 cooperate to form a second mounting cavity 1214. The reinforcing component 12 also includes a support member 122, which is disposed in the second mounting cavity 1214. The support member 122 abuts against another support wall 113, that is, one support wall 113 of the mounting member 11 abuts against the first base 1211, and the other support wall 113 abuts against the support member 122. In this embodiment, the reinforcing component 12 abuts against each mounting wall 112 and each support wall 113 through the cooperation of the base 121 and the support member 122, thereby improving the load-bearing capacity of the tow hook assembly 10 and improving the bending and torsional stiffness of the mounting member 11.

[0042] Furthermore, the tow hook assembly 10 also has a third direction Y, with the first direction Z, the second direction X, and the third direction Y being mutually perpendicular. The base 121 also includes a third base 1213, which is disposed on at least one side of the first base 1211 in the third direction Y. The first base 1211 is also connected to the second base 1212 through the third base 1213. In this way, the third base 1213 can enhance the connection strength between the first base 1211 and the second base 1212, thereby improving the overall structural strength of the base 121 and further enhancing the load-bearing capacity of the tow hook assembly 10.

[0043] For example, the base 121 can be a stamped sheet metal part, etc. The first base 1211 is integrally formed with the second base 1212 and the third base 1213. The second base 1212 is located on both sides of the first base 1211 in the first direction Z, and the second base 1212 is folded over the first base 1211. The third base 1213 is located on both sides of the first base 1211 in the third direction Y, and the third base 1213 is folded over the first base 1211. The second base 1212 and the third base 1213 are welded together, so that the base 121 forms a five-sided structure. That is, the base 121 has an opening on the side of the second direction X opposite to the first base 1211. The opening communicates with the second mounting cavity 1214, and the support member 122 abuts against the support wall 113 through the opening.

[0044] In one embodiment, the support member 122 includes a first sub-support member 1221 and a second sub-support member 1222. The first sub-support member 1221 includes a first main body portion 1223 and a first support portion 1224, with the first support portion 1224 connected to the first main body portion 1223 on one side in the second direction X. The second sub-support member 1222 includes a second main body portion 1225 and a second support portion 1226, with the second support portion 1226 connected to the second main body portion 1225 on one side in the second direction X.

[0045] In this embodiment, the first main body portion 1223 of the first sub-support member 1221 and the second main body portion 1225 of the second sub-support member 1222 abut against each other, that is, the support member 122 is a reinforced structure formed by the first sub-support member 1221 and the second sub-support member 1222 back to back. The first main body portion 1223 and the second main body portion 1225 can be connected by spot welding or other methods. Furthermore, the first support portion 1224 of the first sub-support member 1221 and the second support portion 1226 of the second sub-support member 1222 both abut against the support wall 113, realizing the abutment between the support member 122 and the support wall 113. In this embodiment, the first sub-support member 1221 and the second sub-support member 1222 can abut against the support wall 113 stably and reliably, which is beneficial to further improving the load-bearing capacity of the tow hook assembly 10.

[0046] Furthermore, the first sub-support member 1221 also includes a third support portion 1227, which is connected to the first main body portion 1223 on the other side in the second direction X. The second sub-support member 1222 also includes a fourth support portion 1228, which is connected to the second main body portion 1225 on the other side in the second direction X. Both the third support portion 1227 and the fourth support portion 1228 abut against the first base portion 1211, which can improve the overall structural strength of the reinforcing assembly 12 and is beneficial to further improving the load-bearing capacity of the tow hook assembly 10.

[0047] For example, in the third direction Y, the first support portion 1224 is located on the side of the first main body portion 1223 away from the second main body portion 1225, and the second support portion 1226 is located on the side of the second main body portion 1225 away from the first main body portion 1223. Furthermore, in the third direction Y, at least a portion of the third support portion 1227 is away from the first main body portion 1223 relative to the first support portion 1224, and at least a portion of the fourth support portion 1228 is away from the second main body portion 1225 relative to the second support portion 1226. In this way, the first sub-support 1221 and the second sub-support 1222 form a stable triangular structure. The first sub-support 1221 and the second sub-support 1222 can stably and reliably support the first base 1211 of the base 121, improving the overall structural strength of the reinforcing assembly 12. Furthermore, the first sub-support 1221 and the second sub-support 1222 can stably and reliably abut against the support wall 113, which further enhances the load-bearing capacity of the tow hook assembly 10. There are at least two sets of support members 122, with each set spaced apart from the others. Each set of support members 122 cooperates to abut against the support wall 113, further improving the load-bearing capacity of the tow hook assembly 10. Figures 3 to 5 An example is shown where there are two sets of support members 122, which are distributed at intervals along the third direction Y.

[0048] Please refer to the following: Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of an embodiment in which the support sleeve is disposed between the first sub-support member and the second sub-support member. Figure 7 yes Figure 1 The diagram shows a structural schematic of the tow hook assembly from another perspective.

[0049] In one embodiment, the mounting walls 112 on both sides of the first mounting cavity 111 in the first direction Z include a first mounting wall 112a and a second mounting wall 112b, and the tow hook 13 is disposed on the side of the first mounting wall 112a away from the second mounting wall 112b. The reinforcing assembly 12 includes a first fixing member 124, which extends from the second mounting wall 112b through the first mounting wall 112a in the first direction Z and is connected to the tow hook 13. In other words, in this embodiment, the first fixing member 124 adopts a through-connection design to fix the tow hook 13 to the mounting member 11 and also connects the tow hook 13 to the reinforcing assembly 12. This allows the entire inner cavity of the mounting member 11 (i.e., the first mounting cavity 111) to participate in bearing the load, which is beneficial to further improve the load-bearing capacity of the tow hook assembly 10.

[0050] Specifically, the reinforcing assembly 12 also includes a support sleeve 123, which is disposed between the first sub-support 1221 and the second sub-support 1222. The support sleeve 123 has an axially extending mounting hole 1231 inside, through which the first fixing member 124 also passes. The support sleeve 123 extends along a first direction Z, supporting the second bases 1212 on both sides of the first base 1211 in the first direction Z. This improves the overall structural strength of the reinforcing assembly 12 and further enhances the load-bearing capacity of the tow hook assembly 10.

[0051] For example, the support sleeve 123 is connected to the first sub-support 1221 and the second sub-support 1222 respectively via welds on both sides. After the support sleeve 123 is welded to the support 122, the support 122 is installed into the second mounting cavity 1214 of the base 121. The support 122 and the base 121 can be connected by welding or other methods. In the example where there are two groups of support 122, each group of support 122 is provided with a support sleeve 123, and the number of first fixing members 124 corresponds to the number of groups of support 122, that is, there are two first fixing members 124. After the support 122 is installed into the second mounting cavity 1214 of the base 121, the reinforcing component 12 is installed into the first mounting cavity 111 of the mounting component 11. The mounting component 11 may include an outer plate and an inner plate. Specifically, the reinforcing component 12 is installed into the inner plate and connected to the inner plate by spot welding. The spot welding position can be arranged according to the specific stress conditions. The outer and inner panels are then welded together, and the reinforcing component 12 is welded to the outer panel via weld seams. After the reinforcing component 12 is installed into the first mounting cavity 111 of the mounting member 11, each first fixing member 124 is inserted from the second mounting wall 112b of the mounting member 11 along the first direction Z to the first mounting wall 112a and connected to the tow hook member 13. Each first fixing member 124 is inserted into the mounting hole 1231 of its corresponding support sleeve 123.

[0052] In one embodiment, the tow hook 13 includes a tow hook body 131 and a connecting portion 132. The tow hook body 131 is fixed to the side of the first mounting wall 112a away from the second mounting wall 112b by a first fixing member 124. The connecting portion 132 is connected to the side of the tow hook body 131 close to the second mounting wall 112b, and the connecting portion 132 is fixed to the support wall 113 by a second fixing member 125. In this embodiment, the tow hook 13 achieves an off-plane overlapping design with the mounting member 11 through the tow hook body 131 and the connecting portion 132. Compared with the single-sided connection between the tow hook 13 and the mounting member 11, this embodiment can increase the contact area between the tow hook 13 and the mounting member 11 and optimize the stress distribution between the tow hook 13 and the mounting member 11, making the stress distribution more reasonable and helping to further improve the load-bearing capacity of the tow hook assembly 10.

[0053] Specifically, in the second direction X, the connecting portion 132 is located on the side of the tow hook body 131 near the first base 1211 of the base 121, and the connecting portion 132 is located on the side of the support wall 113 opposite to the first base 1211. The second fixing member 125 passes through the tow hook member 13 (i.e., the connecting portion 132) and the support wall 113 along the second direction X, and the first fixing member 124 and the second fixing member 125 cooperate to fix the tow hook member 13 to the mounting member 11.

[0054] For example, the number of second fasteners 125 can be one or more. Figure 7 The example demonstrates a case where there are two second fasteners 125, which cooperate to fix the tow hook 13 to the mounting member 11. The tow hook body 131 and the connecting part 132 of the tow hook 13 are generally L-shaped. The tow hook body 131 is fixed to the mounting member 11 by two first fasteners 124, and the connecting part 132 is fixed to the mounting member 11 by two second fasteners 125. That is, the tow hook 13 and the mounting member 11 are fixedly connected at four points with different surfaces. This design increases the contact area between the tow hook 13 and the mounting member 11 and optimizes the stress distribution between them, resulting in a more reasonable stress distribution and further improving the load-bearing capacity of the tow hook assembly 10.

[0055] It should be noted that the load-bearing capacity of the tow hook assembly 10 in the ±Z (i.e., the first direction and its opposite), ±X (i.e., the second direction and its opposite), and ±Y (i.e., the third direction and its opposite) directions is subject to assessment requirements. The reinforcing component 12 of this embodiment can significantly improve the bending and torsional stiffness of the mounting member 11 at the tow hook assembly 10 in all directions, and the tow hook member 13 has increased lap contact surface with the mounting member 11 through the reinforcing component 12. This design provides a more reasonable stress distribution and sufficient bending and torsional support to the mounting member 11 when a load is applied to the tow hook member 13. Compared to traditional tow hooks, the tow hook assembly 10 in this embodiment has a towing load mass increased by more than 5 times, while fully meeting the strength requirements. Furthermore, the optimization of plate thickness enables a lightweight design, meeting user requirements for towable caravans (RVGW) while reducing overall vehicle costs.

[0056] The technical solutions provided in the embodiments of this application will be described below with reference to specific examples.

[0057] Example 1:

[0058] The tow hook assembly 10 has a first direction Z and a second direction X. When the tow hook assembly 10 is installed on the vehicle body, the first direction Z is parallel to the height direction of the vehicle body, and the second direction X is parallel to the length direction of the vehicle body. The tow hook assembly 10 includes a mounting member 11 for connecting to the vehicle body. The mounting member 11 has a first mounting cavity 111 inside, with mounting walls 112 on both sides in the first direction Z and support walls 113 on both sides in the second direction X. The tow hook assembly 10 also includes a reinforcing component 12 disposed in the first mounting cavity 111, abutting against each mounting wall 112 and each support wall 113. The tow hook assembly 10 also includes a tow hook member 13 disposed on the mounting member 11 and connected to the reinforcing component 12.

[0059] The tow hook 13 is connected to the reinforcing assembly 12, which abuts against each mounting wall 112 and each supporting wall 113. That is, the reinforcing assembly 12 provides four-sided support in the first mounting cavity 111 inside the mounting member 11. The tow hook 13 increases the overlapping contact surface with the mounting member 11 through the reinforcing assembly 12. When the load is applied to the tow hook 13, the reinforcing assembly 12 can provide a more reasonable stress distribution and provide sufficient bending and torsional support to the mounting member 11, which can greatly improve the load-bearing capacity of the tow hook assembly 10 and improve the bending and torsional stiffness of the mounting member 11, thus meeting the user's requirements for the RVGW of the towed caravan.

[0060] Example 2:

[0061] The first mounting cavity 111 has mounting walls 112 on both sides in the first direction Z, including a first mounting wall 112a and a second mounting wall 112b. The tow hook 13 is disposed on the side of the first mounting wall 112a away from the second mounting wall 112b. The reinforcing assembly 12 includes a first fixing member 124, which extends from the second mounting wall 112b through the first mounting wall 112a in the first direction Z and connects to the tow hook 13. In other words, the first fixing member 124 adopts a through-connection design to fix the tow hook 13 to the mounting member 11 and also connects the tow hook 13 to the reinforcing assembly 12. This allows the entire inner cavity of the mounting member 11 (i.e., the first mounting cavity 111) to participate in bearing the load, which is beneficial to further improve the load-bearing capacity of the tow hook assembly 10.

[0062] Example 3:

[0063] The tow hook assembly 13 includes a tow hook body 131 and a connecting portion 132. The tow hook body 131 is fixed to the side of the first mounting wall 112a away from the second mounting wall 112b by a first fixing member 124. The connecting portion 132 is connected to the side of the tow hook body 131 close to the second mounting wall 112b, and is fixed to the support wall 113 by a second fixing member 125. The tow hook assembly 13 achieves an off-plane overlapping design with the mounting member 11 through the tow hook body 131 and the connecting portion 132. Compared with the single-sided connection between the tow hook assembly 13 and the mounting member 11, this increases the contact area between the tow hook assembly 13 and the mounting member 11 and optimizes the stress distribution between them, resulting in a more reasonable stress distribution and further improving the load-bearing capacity of the tow hook assembly 10.

[0064] In summary, this application provides a tow hook assembly and a vehicle. The tow hook assembly has a first mounting cavity inside its mounting member. The first mounting cavity has mounting walls on both sides in a first direction and support walls on both sides in a second direction. The tow hook component of the tow hook assembly is disposed on the mounting member and is connected to a reinforcing assembly. The reinforcing assembly abuts against each mounting wall and each support wall, meaning that the reinforcing assembly provides four-sided support within the first mounting cavity inside the mounting member. This significantly improves the load-bearing capacity of the tow hook assembly and the bending and torsional stiffness of the mounting member, meeting the user's requirements for RVGW (RV Wheelhouse).
