[0031] Reference below Figure 1-Figure 5 A trailer hook assembly 100 according to an embodiment of the present invention is described.

[0032] Reference Figure 1 , Figure 2 According to an embodiment of the utility model, a trailer hook assembly 100 includes: a trailer part 20.

[0033] The trailer component 20 includes: a trailer portion 21, a first connection portion 22 and a second connection portion 23. The trailer portion 21 is used for towing a vehicle. The first connection portion 22 and the second connection portion 23 are respectively arranged on opposite sides of the trailer portion 21. The first connection portion 22 and the second connection portion 23 are respectively connected to the longitudinal beam 10 to fix the trailer component 20 to the longitudinal beam 10.

[0034] The trailer hook assembly 100 is usually installed on the vehicle body or frame, and is used to connect a trailer or other towing equipment. The trailer hook assembly 100 is mainly used to tow a trailer or other vehicles and equipment, such as a trailer, a boat, a camper, etc. By connecting the trailer hook assembly 100, the vehicle can tow the trailer or other equipment to a destination, such as transporting goods, traveling, moving, etc.

[0035] The trailer part 21 is used for towing the vehicle, and the first connection part 22 and the second connection part 23 play a connecting role. The first connection part 22 and the second connection part 23 on the trailer part 20 are respectively connected to the longitudinal beam 10 to fix the trailer part 20 on the longitudinal beam 10.

[0036] In the related art, a trailer hook is used for towing a vehicle. The trailer hook generally includes a connecting portion and a traction portion. The connecting portion is provided with a through hole for passing a traction rope. The traction portion is connected to one end of the connecting portion. The traction portion is fixed to the longitudinal beam of the vehicle by a plurality of bolts. The plurality of bolts are located on the same side of the connecting portion. The traction capacity of the trailer hook is relatively low.

[0037] In the embodiment of the utility model, the first connection part 22 and the second connection part 23 are respectively arranged on the opposite sides of the trailer part 21, and the trailer part 21 is located between the first connection part 22 and the second connection part 23. During the operation of the trailer hook assembly 100, the trailer part 21 transfers the force received to the trailer component 20, and the trailer component 20 transfers the force to the longitudinal beam 10 through the first connection part 22 and the second connection part 23 on the opposite sides of the trailer part 21. The force is more balanced, and the trailer hook assembly 100 can withstand a greater force, thereby improving the traction capacity of the trailer hook assembly 100.

[0038] Among them, the first connection part 22 can be single or multiple, and multiple first connection parts 22 increase the connection stability; the second connection part 23 can be single or multiple, and multiple second connection parts 23 increase the connection stability.

[0039] Specifically, the first connection portion 22 may be a first connection hole, in which a first connection member 221, such as a bolt or a screw, for connecting the longitudinal beam 10 is disposed; or, the first connection portion 22 is configured as a first welding portion, and the first welding portion is welded to the longitudinal beam 10. The second connection portion 23 may be a second connection hole, in which a second connection member 231, such as a bolt or a screw, for connecting the longitudinal beam 10 is disposed; or, the second connection portion 23 is configured as a second welding portion, and the second welding portion is welded to the longitudinal beam 10.

[0040] According to the trailer hook assembly 100 of the embodiment of the utility model, by respectively arranging the first connection part 22 and the second connection part 23 on the opposite sides of the trailer part 21, the trailer part 20 transmits the force to the longitudinal beam 10 through the first connection part 22 and the second connection part 23 on the opposite sides of the trailer part 21, the force is more balanced, the trailer hook assembly 100 can withstand a greater force, thereby improving the traction capacity of the trailer hook assembly 100.

[0041] Reference Figures 1 to 5 In some embodiments, the trailer hook assembly 100 further includes: a mounting bracket 30 , the mounting bracket 30 is disposed on the longitudinal beam 10 , and the trailer component 20 is mounted on the mounting bracket 30 .

[0042] The mounting bracket 30 is located between the longitudinal beam 10 and the trailer component 20 , and the mounting bracket 30 provides a position for installing the trailer component 20 .

[0043] In the above scheme, the mounting bracket 30 is installed between the trailer part 20 and the longitudinal beam 10, and the trailer part 20 is indirectly installed on the longitudinal beam 10 by using the mounting bracket 30. The length of the trailer part 20 is shorter, thereby shortening the force arm of the trailer part 20 in operation, and improving the upper force limit of the trailer hook assembly 100.

[0044] For example, the mounting bracket 30 is installed on the lower side of the longitudinal beam 10, and the trailer part 20 is installed below the mounting bracket 30. The trailer part 20 needs to be installed at a position 50 mm away from the longitudinal beam 10. The height of the portion of the mounting bracket 30 outside the longitudinal beam 10 is 20 mm. Therefore, the height of the trailer part 20 only needs to be designed to be 30 mm instead of 50 mm, thereby shortening the lever arm during operation.

[0045] Reference Figure 3 In some embodiments, the mounting bracket 30 at least partially wraps the longitudinal beam 10 .

[0046] The mounting bracket 30 may completely wrap the longitudinal beam 10 , or may partially wrap the longitudinal beam 10 . When the mounting bracket 30 wraps the longitudinal beam 10 , the mounting bracket 30 partially overlaps with the longitudinal beam 10 , and the mounting bracket 30 fits the longitudinal beam 10 .

[0047] In the above scheme, by setting the mounting bracket 30 to at least partially wrap the longitudinal beam 10, the contact area between the mounting bracket 30 and the longitudinal beam 10 is increased, and the stability is improved. At the same time, the overall volume of the mounting bracket 30 and the longitudinal beam 10 is smaller, and the force arm during the working process can also be shortened, thereby increasing the upper force limit of the trailer hook assembly 100.

[0048] For example, the mounting bracket 30 is installed on the lower side of the longitudinal beam 10 , the trailer component 20 is installed below the mounting bracket 30 , a portion of the mounting bracket 30 wraps around the longitudinal beam 10 , and the remaining portion of the mounting bracket 30 is located below the longitudinal beam 10 .

[0049] Reference Figure 2 , Figure 3 In some embodiments, the mounting bracket 30 includes: a bracket body 31 and an extension portion 32 .

[0050] The bracket body 31 is disposed below the longitudinal beam 10. The extension portion 32 is disposed on the bracket body 31 and extends in a direction away from the trailer member 20. In the height direction, the extension portion 32 at least partially overlaps with the longitudinal beam 10.

[0051] The extension portion 32 is disposed on the bracket body 31 , the trailer part 20 and the longitudinal beam 10 are located on both sides of the mounting bracket 30 , and the extension portion 32 extends away from the trailer part 20 , that is, the extension portion 32 extends toward the longitudinal beam 10 , and the extension portion 32 wraps the longitudinal beam 10 .

[0052] In the above solution, by providing the extension part 32 on the bracket body 31 to wrap the longitudinal beam 10 , the contact area between the extension part 32 and the longitudinal beam 10 is large, thereby improving the connection stability and facilitating the assembly of the rear longitudinal beam 10 and the mounting bracket 30 .

[0053] Reference Figure 5 In some embodiments, the mounting bracket 30 is constructed as a stamping part, the bracket body 31 is provided with an inclined surface 311, the first connecting portion 22 is connected to a portion of the bracket body 31 different from the inclined surface 311, and the second connecting portion 23 is connected to the inclined surface 311. In the front-to-back direction, the distance between the inclined surface 311 and the longitudinal beam 10 gradually decreases.

[0054] Among them, the mounting bracket 30 is constructed as a stamped part, that is, the mounting bracket 30 is stamped and formed, and a slope 311 is arranged on the bracket body 31. The slope 311 is arranged in the front-to-back direction, that is, in the direction from the front to the rear of the vehicle. The distance between the slope 311 and the longitudinal beam 10 gradually decreases, and the depth of the mounting bracket 30 gradually decreases.

[0055] At the same time, the bracket body 31 can be divided into at least two parts, the inclined surface 311 is the first part, and the part of the bracket body 31 different from the inclined surface 311 is the second part. The first connecting part 22 and the second connecting part 23 respectively connect the first part and the second part. The structure of the inclined surface 311 increases the distance between the first connecting part 22 and the second connecting part 23.

[0056] In the above scheme, the mounting bracket 30 is constructed as a stamping part. The mounting bracket 30 is stamped and formed. A bevel 311 is provided on the bracket body 31 to reduce the stamping depth, which is beneficial to the management of stamping and single-piece precision, reduces the probability of the bracket body 31 being weak and damaged due to excessive depth, and reduces the defective rate in the manufacturing process. At the same time, the second connecting part 23 is connected to the bevel 311, and the first connecting part 23 is connected to other parts of the bracket body 31. The structure of the bevel 311 increases the distance between the first connecting part 23 and the second connecting part 23, so that the connection between the trailer part 20 and the mounting bracket 30 is more stable.

[0057] In some embodiments, a first welding portion is provided between an edge of the extension portion 32 and the longitudinal beam 10 .

[0058] The first welding portion is located between the edge of the extension portion 32 and the longitudinal beam 10 , that is, the mounting bracket 30 and the longitudinal beam 10 are connected by a welding process.

[0059] In the above scheme, the longitudinal beam 10 and the extension portion 32 are connected by a welding process, which improves the connection stability. The welding process can be gas shielded welding, such as carbon dioxide shielded welding or others. The edge of the extension portion 32 is connected to the longitudinal beam 10 by welding to increase the connection area.

[0060] In some other embodiments, a through hole 321 is provided on the extension portion 32 , a second welding portion is provided in the through hole 321 , and the second welding portion is connected to the longitudinal beam 10 .

[0061] The through hole 321 on the extension portion 32 is provided with a second welding portion, the second welding portion is connected to the longitudinal beam 10 , and the second welding portion is an intermediate connecting component between the longitudinal beam 10 and the extension portion 32 , so that the mounting bracket 30 is fixed to the longitudinal beam 10 .

[0062] In the above solution, the longitudinal beam 10 and the extension portion 32 are connected by a welding process, which improves the connection stability. The welding process may be plug welding, which further improves the connection strength.

[0063] Specifically, plug welding is a metalworking process also known as "filler welding" or "filler welding". Plug welding is used to repair or join metal parts. During the plug welding process, the welder will use filler material to fill the metal surface or gap that needs to be joined or repaired, and then heat to melt the filler material so that it fuses with the metal base material to form a uniform weld.

[0064] In other embodiments, a first welding portion is provided between the edge of the extension portion 32 and the longitudinal beam 10 , a through hole 321 is provided on the extension portion 32 , a second welding portion is provided in the through hole 321 , and the second welding portion is connected to the longitudinal beam 10 .

[0065] The longitudinal beam 10 and the extension portion 32 are connected by a plurality of welding portions, the welding portions include a first welding portion and a second welding portion, and the connection at a plurality of positions makes the connection between the longitudinal beam 10 and the mounting bracket 30 more stable. The first welding portion is a welding portion left by a welding process, and the welding process may be gas shielded welding, such as carbon dioxide shielded welding or others, and the second welding portion is a welding portion left by a welding process, such as plug welding.

[0066] In the above solution, the longitudinal beam 10 and the mounting bracket 30 are connected by providing a first welding portion and a second welding portion, and multiple welding locations are provided to improve the connection stability.

[0067] In some embodiments, the trailer portion 21 extends obliquely backward, the first connection portion 22 is disposed at the front side of the trailer portion 21 , the second connection portion 23 is disposed at the rear side of the trailer portion 21 , and the number of the first connection portions 22 is greater than the number of the second connection portions 23 .

[0068] It can be understood that the direction of the front of the vehicle is front, the direction of the rear of the vehicle is rear, and the trailer part 21 extends toward the rear of the vehicle. Compared with the trailer part 21, the first connection part 22 is closer to the front of the vehicle, and the second connection part 23 is closer to the rear of the vehicle. The number of the first connection parts 22 is greater than the number of the second connection parts 23. For example, there are two first connection parts 22 and one second connection part 23, or there are more first connection parts 22 and the second connection part 23 is less than the first connection part 22.

[0069] In the above scheme, by arranging the first connection part 22 on the front side of the trailer part 21 and the second connection part 23 on the rear side of the trailer part 21, and the number of the first connection parts 22 is greater than the number of the second connection parts 23, during the operation of the trailer hook assembly 100, the distribution of the first connection part 22 and the second connection part 23 is more adapted to the stress condition of the trailer part 20, thereby improving the performance of the trailer hook assembly 100.

[0070] Specifically, the trailer part 21 extends obliquely toward the rear of the vehicle, the first connection part 22 is arranged on the front side of the trailer part 21, and there are two first connection parts 22, and the second connection part 23 is arranged on the rear side of the trailer part 21, and there is one second connection part 23. When the trailer hook assembly 100 tows other vehicles, the trailer hook assembly 100 is subjected to a backward pulling force, and the two first connection parts 22 adapt to the force conditions, thereby improving the performance of the trailer hook assembly 100.
