The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0029] In the related art, due to the traction force from the rearwardly towed vehicle by the trailer hitch assembly acting on the cross beam of the vehicle, the connection between the cross beam and the trailer hitch assembly is prone to breakage, resulting in the detachment of the trailer hitch assembly.

[0030] The following refers to Figures 1-5 to describe a trailer hitch assembly for a vehicle according to an embodiment of the present utility model.

[0031] The trailer hitch assembly 100 for a vehicle according to the present utility model includes: a cross beam 11, a mounting seat 12, a support block 13, and a trailer hitch support 14. The mounting seat 12 is disposed on the cross beam 11, and the mounting seat 12 protrudes from the outer peripheral surface of the cross beam 11; the support block 13 is disposed on the surface of the cross beam 11 and the end thereof is connected to the mounting seat 12; the trailer hitch support 14 is fixedly connected to the mounting seat 12; wherein the support block 13 is configured such that the cross-sectional area gradually decreases in the direction away from the mounting seat 12.

[0032] In some specific embodiments, the trailer hitch assembly 100 is composed of a cross beam 11, a mounting seat 12, a support block 13, and a trailer hitch support 14. The support block 13 and the mounting seat 12 are both disposed on the cross beam 11. The cross beam 11 connects the vehicle to the trailer hitch assembly 100. The mounting seat 12 protrudes from the outer peripheral surface of the cross beam 11 to provide a fixed point for the trailer hitch support 14. The end of the support block 13 is connected to the mounting seat 12, and the trailer hitch support 14 is fixedly connected to the mounting seat 12. The trailer hitch support 14 can be used to fix the trailer hitch to ensure the stability and safety of the trailer hitch during the towing process. The cross-sectional area of the support block 13 gradually decreases in the direction away from the mounting seat 12, increasing the contact area between the support block 13 and the cross beam 11, which helps to evenly disperse the force exerted by the trailer hitch on the cross beam 11, avoid stress concentration on the cross beam 11, and thus effectively prevent the cross beam 11 from breaking and improve the load-bearing capacity and stability of the entire trailer hitch assembly 100.

[0033] According to the trailer hitch assembly 100 of the present invention, a support block 13 is provided on the cross beam 11. The end of the support block 13 is connected to the mounting seat 12, and the trailer hitch support 14 is fixedly connected to the mounting seat 12. The cross-sectional area of the support block 13 gradually decreases in the direction away from the mounting seat 12, increasing the contact area between the support block 13 and the cross beam 11, which helps to evenly disperse the force exerted by the trailer hitch on the cross beam 11, avoid stress concentration on the cross beam 11, and thus effectively prevent the cross beam 11 from breaking and improve the load-bearing capacity and stability of the entire trailer hitch assembly 100.

[0034] According to some embodiments of the present invention, the cross beam 11 is configured as a tubular shape. Compared with a solid structure, the tubular structure can provide higher strength and rigidity with the same amount of material used. The tubular structure can utilize materials more effectively, resist bending and twisting, and improve the structural strength and stiffness of the cross beam 11. At the same time, the hollow design of the tubular cross beam 11 also reduces the weight, improves the fuel efficiency and handling performance of the vehicle. The mounting seat 12 is sleeved on the cross beam 11, and the mounting seat 12 and the cross beam 11 form a tightly combined structure, improving the overall stability and strength of the trailer hitch assembly 100 and the cross beam 11 after connection. At the same time, the sleeving method simplifies the installation and disassembly process, facilitating the maintenance and adjustment of the trailer hitch assembly 100.

[0035] According to some embodiments of the present invention, the wall thickness of the cross beam 11 is d and satisfies: 4 mm ≤ d ≤ 10 mm.

[0036] In some specific embodiments, the cross beam 11 can be made of high-strength alloy steel (such as 25CrMo4). High-strength alloy steel is an alloy steel with high yield strength and good toughness. When the vehicle collides or receives the traction force from the rear vehicle, it can absorb more energy without breaking easily, thereby protecting the passengers from harm or preventing separation from the rear vehicle during the process of towing the rear vehicle. The wall thickness of the cross beam 11 is d, and it satisfies: 4mm ≤ d ≤ 10mm. Preferably, the wall thickness of the cross beam 11 can be 7mm. The 7mm wall thickness can ensure that the cross beam 11 has sufficient rigidity to resist the impact force during collision and the traction force from the tow hook, preventing the cross beam 11 from deforming or breaking prematurely, and thus maintaining the safety and stability of the vehicle during normal operation.

[0037] According to some embodiments of the present invention, a plurality of mounting seats 12 are configured. By using a plurality of mounting seats 12 to connect with the cross beam 11, the load can be more evenly distributed on the cross beam 11, reducing the stress concentration at a single connection point, thereby improving the stability and load-bearing capacity of the overall structure. This design is particularly suitable for vehicles that need to bear heavy loads or perform frequent towing tasks, and can significantly enhance the durability and safety of the tow hook assembly 100. A support surface for fixing to the tow hook support 14 is formed at the end of the mounting seat 12. The tow hook support 14 is respectively fixedly connected to the support surfaces of a plurality of mounting seats 12. A support surface is provided at the end of each mounting seat 12, and the support surface is used for fixedly connecting with the tow hook support 14. The plurality of independent support surfaces provide more contact points, increasing the connection area between the tow hook support 14 and the mounting seat 12, thereby enhancing the connection strength between the tow hook support 14 and the mounting seat 12 and improving the reliability of the connection between the tow hook support 14 and the mounting seat 12.

[0038] According to some embodiments of the present invention, the support block 13 is configured as a wedge-shaped block, that is, the support block 13 has one or two opposite inclined surfaces. One end of the support block 13 is wider, and the other end of the support block 13 gradually narrows. The design of the wedge-shaped block helps to evenly disperse the force applied to the tow hook assembly 100, avoiding stress concentration, thereby improving the stability and safety of the connection between the tow hook assembly 100 and the cross beam 11. The bottom surface of the wedge-shaped block is configured as an arc surface that fits the cross beam 11. On the one hand, it increases the contact area between the support block 13 and the cross beam 11, thereby improving the connection strength between the support block 13 and the cross beam 11 and ensuring the reliability of the structure of the tow hook assembly 100 when bearing heavy loads. On the other hand, it makes the support block 13 fit more closely with the cross beam 11, and the force received by the tow hook can be better transmitted from the support block 13 to the cross beam 11.

[0039] According to some embodiments of the present invention, a welding layer is provided between the edge of the arc surface of the support block 13 and the outer surface of the cross beam 11.

[0040] In some specific embodiments, the connection between the support block 13 and the cross beam 11 is achieved by providing a welding layer between the edge of the arc surface of the support block 13 and the outer surface of the cross beam 11. The support block 13 and the cross beam 11 are welded together. The welding layer provides a direct metal-to-metal connection between the support block 13 and the cross beam 11. Compared with other connection methods (such as bolt connection or riveting), the welding layer can provide higher structural strength and rigidity, ensuring that the support block 13 can effectively transfer the load to the cross beam 11, enhancing the load-bearing capacity and impact resistance of the entire trailer hitch assembly 100. The use of the welding layer ensures the reliability of the connection between the support block 13 and the cross beam 11, avoiding loosening or failure of the connection between the support block 13 and the cross beam 11 due to vibration or external forces. The welded connection can maintain a stable connection state during long-term use, reducing the maintenance requirements and extending the service life of the trailer hitch assembly 100.

[0041] According to some embodiments of the present invention, a trailer hitch mounting groove 101 adapted to accommodate the trailer hitch is formed on the trailer hitch support 14. The trailer hitch mounting groove 101 provides precise positioning for the installation of the trailer hitch, ensuring that the trailer hitch can be quickly and accurately installed on the trailer hitch support 14 without a complex adjustment or calibration process, greatly improving the convenience and efficiency of the assembly of the trailer hitch and the trailer hitch support 14. In addition, as long as the sizes of different types of trailer hitches match the mounting groove, the same set of trailer hitch assembly 100 can be used, eliminating the need to design a dedicated support for each type of trailer hitch, reducing costs and improving the utilization rate of resources.

[0042] According to some embodiments of the present invention, the trailer hitch assembly 100 further includes: a trailer hitch. One end of the trailer hitch is formed with a plug-in end detachably disposed in the trailer hitch mounting groove 101. The detachable connection between the plug-in end of the trailer hitch and the trailer hitch mounting groove 101 allows the user to easily install or remove the trailer hitch as needed without professional tools, simplifying the operation process and improving the convenience of use. The user can also replace different types of trailer hitches according to different towing requirements. For example, replacing a heavy-duty trailer hitch with a light-duty trailer hitch, or replacing a trailer hitch with different connection devices to adapt to different types of trailers or loads. The detachable characteristic of the trailer hitch allows it to be easily removed when not in use, facilitating storage and transportation, reducing the occupied space, and also avoiding the impact on the vehicle appearance when not in use. The other end of the trailer hitch is formed with a ball head 23, and the ball head 23 is connected to the components on the towed vehicle, enabling the trailer hitch assembly 100 to withstand various forces during the towing process, including longitudinal tensile force, lateral shear force, and up-and-down bumping force, ensuring a safe and stable connection between the towing vehicle and the towed vehicle.

[0043] According to some embodiments of the present utility model, the trailer hitch assembly 100 further includes: a latch pin 22, which is adapted to pass through the trailer hitch mounting groove 101 and the insertion end 21 of the trailer hitch to restrict the relative movement between the trailer hitch and the trailer hitch support 14.

[0044] In some specific embodiments, a latch pin 22 is also provided within the trailer hitch assembly 100. The latch pin 22 is used to pass through the trailer hitch mounting groove 101 and the insertion end 21 of the trailer hitch to form a mechanical locking mechanism between the trailer hitch mounting groove 101 and the trailer hitch insertion end. After the insertion end 21 of the trailer hitch is inserted into the trailer hitch mounting groove 101, the latch pin 22 passes through from the side and fixes it within the mounting groove, thereby restricting the relative movement between the trailer hitch and the trailer hitch support 14, ensuring a firm connection of the trailer hitch during towing, and avoiding the risk of accidental loosening of the trailer hitch.
