[0038] The trailer hitch assembly 10 and the vehicle according to an embodiment of the present invention are described in detail below with reference to the accompanying drawings.

[0039] Reference Figures 1-4As shown, the trailer hitch assembly 10 according to an embodiment of the present invention includes: a mounting beam 1, a trailer hitch 2, and a crash barrier 3. The mounting beam 1 is adapted to be connected to the vehicle body. The trailer hitch 2 includes a drive member 21 and a hook body 22. The drive member 21 is connected to the mounting beam 1 and is used to drive the hook body 22 to move. The crash barrier 3 is connected to the drive member 21 and / or the mounting beam 1, and at least a portion of the crash barrier 3 is located on the side of the mounting beam 1 away from the vehicle body.

[0040] The trailer hitch assembly 10 can be used in vehicles and can be located at the rear of the vehicle. The mounting beam 1 can be used to support and fix the trailer hitch 2. The trailer hitch 2 can be used to tow other vehicles. The anti-collision bracket 3 can protrude behind the mounting beam 1 to support the rear bumper of the vehicle. The mounting beam 1 and the anti-collision bracket 3 can replace the original anti-collision beam structure of the vehicle. In the event of a collision at the rear of the vehicle, the damage to the vehicle can be reduced and the maintenance economy of the vehicle can be improved.

[0041] Specifically, in the front-rear direction, the mounting beam 1 can be located between the vehicle body and the rear bumper. The mounting beam 1 can protect the rear of the vehicle and can also fix the tow hook 2 and the anti-collision bracket 3.

[0042] The trailer hitch 2 includes a drive unit 21 and a hook body 22. The drive unit 21 is fixedly mounted on the mounting beam 1, and the hook body 22 is connected to the drive unit 21. The drive unit 21 can drive the hook body 22 to move relative to the mounting beam 1, so that the hook body 22 extends or retracts relative to the mounting beam 1. (Refer to...) Figure 1 As shown, when the drive unit 21 drives the hook body 22 to extend rearward from the mounting beam 1, a portion of the hook body 22 is located behind the mounting beam 1 and the rear bumper to facilitate connection of a towing device such as a towing rope. (Refer to...)

By driving the hook body 22 to move through the drive unit 21, the extension and retraction of the hook body 22 can be controlled, so that the user can use the trailer hook 2 and avoid the tedious operation of repeatedly disassembling and storing the hook body 22.

[0043] The anti-collision bracket 3 can be connected to at least one of the drive component 21 and the mounting beam 1, and at least a portion of the anti-collision bracket 3 is located on the side of the mounting beam 1 away from the vehicle body. That is, the anti-collision bracket 3 can protrude relative to the mounting beam 1 towards the rear of the vehicle. In the event of a rear-end collision, the mounting beam 1 can support the rear bumper through the anti-collision bracket 3 to prevent excessive deformation of the rear bumper from damaging high-value accessories such as headlights, thereby reducing vehicle repair costs and improving the vehicle's crash repairability.

[0044] Meanwhile, the mounting beam 1 and the anti-collision bracket 3 can replace the original anti-collision beam structure of the vehicle, which helps to reduce the number of rear parts of the vehicle, reduce the cost of the vehicle, and provide sufficient space for the trailer hook 2 to reduce the risk of the hook 22 interfering with other parts when it is in motion.

[0045] According to the present invention, the trailer hitch assembly 10 can be located at the rear of the vehicle. The mounting beam 1 can be used to support and fix the trailer hitch 2. The driving component 21 can drive the hook body 22 to extend and retract, so that the user can use the trailer hitch 2 and avoid the tedious operation of repeatedly disassembling and storing the hook body 22. At the same time, the anti-collision bracket 3 can protrude behind the mounting beam 1 to support the rear bumper of the vehicle. The mounting beam 1 and the anti-collision bracket 3 can replace the original anti-collision beam structure of the vehicle, thereby providing more installation space for the trailer hitch assembly 10, facilitating the arrangement of the trailer hitch assembly 10, reducing vehicle damage in the event of a rear-end collision, and improving the economic efficiency of vehicle maintenance.

[0046] In some embodiments of this utility model, reference is made to Figures 1-3 As shown, there are multiple anti-collision brackets 3, which are arranged at intervals along the extension direction of the mounting beam 1.

[0047] Specifically, the mounting beam 1 can extend along the left and right directions of the vehicle, and multiple anti-collision brackets 3 are arranged at intervals along the left and right directions to support the rear bumper at different positions in the left and right directions, thereby strengthening multiple positions of the bumper, protecting high-value parts at the rear of the vehicle, making it easier for the vehicle to meet the requirements of collision regulations, and further improving the vehicle's crash repairability.

[0048] Reference Figures 1-3 As shown, there are two anti-collision brackets 3, namely a first anti-collision bracket 31 and a second anti-collision bracket 32. The first anti-collision bracket 31 is connected to the rear of the drive component 21, and the second anti-collision bracket 32 ​​is connected to the rear of the mounting beam 1 and located to the right of the first anti-collision bracket 31. At least a portion of the first anti-collision bracket 31 and at least a portion of the second anti-collision bracket 32 ​​are located on the rear side of the mounting beam 1 away from the vehicle body. The first anti-collision bracket 31 and the second anti-collision bracket 32, which are spaced apart to the left and right, can support different positions of the rear bumper to reduce the collision damage to the vehicle. At the same time, the first anti-collision bracket 31 can also protect the drive component 21 and reduce the risk of damage to the drive component 21.

[0049] It should be noted that the anti-collision bracket 3 can be selectively installed at any position on the mounting beam 1 and the drive component 21 to achieve compatibility with different vehicle models, which is beneficial to improving the versatility of the trailer hitch assembly 10.

[0050] In some embodiments of this utility model, reference is made to Figures 1-4As shown, the trailer hitch assembly 10 also includes at least one body connection component 4, the mounting beam 1 being adapted to be connected to the vehicle body via the body connection component 4, and a portion of the body connection component 4 being located on the side of the mounting beam 1 away from the vehicle body.

[0051] Understandably, in the vehicle's longitudinal direction, one part of the body connection assembly 4 is located behind the mounting beam 1, forming a protrusion towards the rear of the mounting beam 1. This protrusion supports the rear bumper, reducing collision damage. The other part of the body connection assembly 4 is located between the mounting beam 1 and the vehicle body, connecting the mounting beam 1 and the vehicle body. Multiple body connection assemblies 4 can be used to improve the stability and reliability of the connection between the mounting beam 1 and the vehicle body, and to provide support for multiple locations on the bumper.

[0052] Reference Figure 1 and Figure 2 As shown, in the extension direction of mounting beam 1, i.e. Figure 1 and Figure 2 In the left and right direction, the two ends of the mounting beam 1 are respectively connected to a body connection component 4. The anti-collision bracket 3 is located between the two body connection components 4. The body connection components 4 and the anti-collision bracket 3 located on the rear side of the mounting beam 1 can be used to support the rear bumper at different positions, so that the vehicle can meet the requirements of collision regulations more easily even without the rear anti-collision beam, thus improving the vehicle's maintenance economy.

[0053] In some embodiments of this utility model, reference is made to Figures 1-4 As shown, the vehicle body connection assembly 4 includes a fixed bracket 41 and a mounting bracket 42.

The design change cost of the trailer hitch assembly 10 is low and its compatibility is good, which is conducive to realizing the platform design of the vehicle and reducing the design and manufacturing costs of the vehicle.

[0056] In some embodiments of this utility model, reference is made to Figure 4 As shown, the fixed bracket 41 includes a first ear plate 411, a second ear plate 412, and a fixed connecting plate 413. The first ear plate 411 and the second ear plate 412 are arranged at intervals relative to each other in the left and right directions. The mounting beam 1 passes through the first ear plate 411 and the second ear plate 412 and is welded to them. A portion of the first ear plate 411 and the second ear plate 412 is located on the side of the mounting beam 1 away from the vehicle body. The fixed connecting plate 413 is connected between the first ear plate 411 and the second ear plate 412. The mounting bracket 42 is detachably connected to the fixed connecting plate 413. The fixed bracket 41 has an overall U-shaped structure, which has good stability and reliability.

[0057] In some embodiments of this utility model, reference is made to Figures 4-6 As shown, the mounting bracket 42 includes a fixing plate 421 and a connecting beam 422. The fixing plate 421 has a mounting hole 4211. The fixing plate 421 is detachably connected to the fixing bracket 41 by a first fastener 5. The connecting beam 422 passes through and is fixed in the mounting hole 4211. The connecting beam 422 is detachably connected to the longitudinal beam of the vehicle body by a second fastener 6.

[0058] Specifically, the connecting beam 422 can be inserted into the mounting hole 4211 on the fixing plate 421, and the connecting beam 422 is fixed to the mounting hole 4211 by welding, bonding or other means. The connection between the connecting beam 422 and the fixing plate 421 is stable and reliable and can withstand large impact loads. The fixing plate 421 can be connected to the fixing bracket 41 by the first fastener 5. The mounting bracket 42 and the fixing bracket 41 can be installed and disassembled by removing and installing the first fastener 5. The connecting beam 422 is connected to the longitudinal beam of the vehicle body by the second fastener 6. The mounting bracket 42 and the vehicle body can be installed and disassembled by removing and installing the second fastener 6.

[0059] In some embodiments, the first fastener 5 may include a first bolt 51 and a first nut 52. The first bolt 51 may be welded and fixed to the fixing plate 421. The first bolt 51 may pass through the fixing bracket 41 and be threadedly engaged with the first nut 52 to connect the fixing plate 421 to the fixing bracket 41 via the first fastener 5. There may be multiple first fasteners 5, which may be arranged around the outside of the mounting hole 4211 to improve the stability and reliability of the connection between the mounting bracket 42 and the fixing bracket 41. The second fastener 6 may include a second bolt 61 and a second nut 62. The second nut 62 may be welded and fixed to the connecting beam 422. The second bolt 61 may pass through the longitudinal beam of the vehicle body and the connecting beam 422 and be threadedly engaged with the second nut 62 to connect the connecting beam 422 to the longitudinal beam of the vehicle body. There may be multiple second fasteners 6, which may be spaced apart along the front-rear direction of the vehicle to improve the stability and reliability of the connection between the mounting bracket 42 and the vehicle body.

[0060] In other embodiments, the first fastener 5 and the second fastener 6 may also be structural components such as locking pins and rivets.

[0061] It should be noted that during the manufacturing and assembly of the mounting bracket 42, different sizes of connecting beams 422 can be selected or the depth of the connecting beams 422 inserted into the mounting holes 4211 can be adjusted to adapt to vehicles with different rear overhang lengths.

[0062] In some embodiments of this utility model, reference is made to Figure 5 and Figure 6 As shown, the mounting bracket 42 further includes a reinforcing plate 423, which is connected to the fixing plate 421. The reinforcing plate 423 has an elongation hole 4231, which is coaxially opposite to and communicates with the mounting hole 4211. The connecting beam 422 passes through and is fixed to the mounting hole 4211 and the elongation hole 4231. The reinforcing plate 423 can improve the strength of the fixing plate 421, and the fixing plate 421 can increase the connection area with the connecting beam 422 through the reinforcing plate 423, thereby improving the reliability and load-bearing capacity of the mounting bracket 42. Optionally, the reinforcing plate 423 and the fixing plate 421 are integrally formed, or the reinforcing plate 423 and the fixing plate 421 are welded together.

[0063] In some embodiments of this utility model, reference is made to Figures 1-3 As shown, the drive unit 21 includes a housing 211 and a motor. The upper end of the housing 211 is connected to the mounting beam 1, and the lower end of the housing 211 is lower than the mounting beam 1 and located between the mounting beam 1 and the vehicle body. At least a portion of the motor is located inside the housing 211. The output shaft of the motor is connected to the hook body 22 to drive the hook body 22 to rotate around a first axis, which is located at the lower end of the housing 211.

[0064] Specifically, the housing 211 is used to fix and protect the motor. The upper end of the housing 211 is connected to the mounting beam 1, and the lower end of the housing 211 is lower than the mounting beam 1 and located between the mounting beam 1 and the vehicle body. That is, the lower end of the housing 211 is located in front of and below the upper end of the housing 211. The housing 211 is tilted to reduce the space occupied by the housing 211 in the vertical direction, which is beneficial to the arrangement of the drive component 21, reduces the negative impact of the drive component 21 on the vehicle's ground clearance, and reduces the risk of interference between the tow hook 2 and other components. In addition, the tilt angle of the housing 211 can be adjusted during assembly to meet the space requirements of different vehicle models.

[0065] The motor can be partially or entirely housed within the housing 211. The motor's output shaft can be directly connected to the hook body 22 via a transmission drive, or the motor's output shaft can be connected to the hook body 22 via a reducer. The motor can drive the hook body 22 to rotate around the first axis, so that the hook body 22 rotates to extend out of the mounting beam 1 and retract into the mounting beam 1. The first axis is located at the lower end of the housing 211, that is, the first axis is located at the lower front position of the mounting beam 1, so as to reduce the risk of interference between the hook body 22 and the mounting beam 1 when the hook body 22 rotates around the first axis.

[0066] In some other embodiments of this utility model, the driving component 21 may be a hydraulic telescopic rod, an electric telescopic rod, etc. The driving component 21 can drive the hook body 22 to move along the front and rear direction of the vehicle by telescopically driving the hook body 22 to extend and retract.

[0067] In some embodiments of this utility model, reference is made to Figure 3 As shown, a connecting groove 2111 is formed at the upper end of the housing 211, and the inner wall of the connecting groove 2111 is fitted and connected to the mounting beam 1.

[0068] Specifically, the mounting beam 1 can be a circular tube beam, which can be made from standard-sized profiles using mature technology to save processing costs. The connecting groove 2111 can be a semi-circular groove adapted to the circular tube beam. The inner wall of the connecting groove 2111 is fitted and connected to the mounting beam 1 to increase the contact area between the housing 211 and the mounting beam 1, thereby improving the reliability and stability of the connection between the housing 211 and the mounting beam 1, and increasing the traction load of the trailer hook 2. It should be noted that the inner wall of the connecting groove 2111 can be connected to the mounting beam 1 by welding, which has good load-bearing capacity.

[0069] In some embodiments of this utility model, reference is made to Figures 1-4 As shown, the trailer hitch assembly 10 also includes a heat shield 23, which covers at least part of the exterior of the drive unit 21.

[0070] Specifically, the heat shield 23 can be connected to the housing 211 of the drive component 21 by four screws 7. The heat shield 23 can isolate the heat of the exhaust system from the drive component 21, so that the drive component 21 can work stably and reliably at a closer distance to the exhaust system, reduce the temperature of the drive component 21, facilitate the arrangement of the tow hook 2, improve the utilization rate of the vehicle's rear space, and reduce the thermal damage of the exhaust system to the drive component 21.

[0071] In some embodiments of this utility model, the heat insulation cover 23 includes a vacuum heat insulation layer and a copper foil layer that are stacked and connected together.

[0072] Specifically, the vacuum insulation layer (VIP) has a low thermal conductivity, good flame retardancy, long service life, and low cost per unit area, which helps to reduce the cost and volume of the heat insulation cover 23 and improve the reliability and service life of the heat insulation cover 23.

[0073] In some implementations, the copper foil layer can be located on the side of the vacuum insulation layer away from the drive unit 21. That is, the copper foil can be located on the outside of the vacuum insulation layer. The copper foil can protect the vacuum insulation layer and has a heat equalization effect to avoid damage to the vacuum insulation layer and reduce the risk of excessive local temperature in the vacuum insulation layer.

[0074] In other embodiments, the copper foil layer may be located on the side of the vacuum insulation layer close to the drive member 21. That is, the copper foil may be located on the inner side of the vacuum insulation layer. The copper foil layer may support the vacuum insulation layer on the inner side of the vacuum insulation layer to ensure the strength of the vacuum insulation layer and prevent the vacuum insulation layer from deforming.

[0075] The trailer hitch assembly 10 according to the present invention can be used in vehicles, especially hybrid vehicles. The heat shield 23 can reduce the heat damage to the trailer hitch 2 caused by the exhaust system's rear muffler. The gap between the drive component 21 and the rear muffler can be shortened to less than 40mm (e.g., 35mm) to improve the space utilization of the rear of the vehicle. The mounting beam 1 and the anti-collision bracket 3 can replace the original anti-collision beam structure of the vehicle to reduce the vehicle's weight, save layout space, and facilitate the installation of the larger trailer hitch 2 while meeting the requirements of collision regulations.

[0076] Meanwhile, for models with different vehicle heights and rear overhang lengths, the specifications of the body connection component 4 and the anti-collision bracket 3 can be adjusted to adapt to the model. The design change cost of the trailer hitch assembly 10 is low, which is conducive to the realization of the platform design of the vehicle.

[0077] The vehicle according to another embodiment of the present invention includes the trailer hitch assembly 10 of the above embodiment.

[0078] According to the embodiment of this utility model, the tow hook assembly 10 of the vehicle can be located at the rear of the vehicle. The mounting beam 1 can be used to support and fix the tow hook 2. The driving component 21 can drive the hook body 22 to extend and retract, so as to facilitate the user's use of the tow hook 2 and avoid the tedious operation of repeatedly disassembling and storing the hook body 22. At the same time, the anti-collision bracket 3 can protrude behind the mounting beam 1 to support the rear bumper of the vehicle.
