DETAILED DESCRIPTION

[0052] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0053] As shown in the background technology, in the prior art, when it is necessary to tow a vehicle, a reinforcement plate is usually added to the rear of the vehicle and a trailer assembly is installed. The trailer assembly includes a crossbeam and a trailer hook. The crossbeam is connected to the rear of the vehicle, and the trailer hook is connected to the vehicle to be towed, thereby transmitting the towing force to the vehicle through the crossbeam. However, this method can only tow lighter vehicles, and the reinforcement plate has a poor effect on strengthening the structure. When the towing force is large, it will still cause certain damage to the vehicle body.

[0054] In response to the above technical problems, an embodiment of the present application provides a rear trailer mounting structure and a vehicle, wherein the rear trailer mounting structure includes a rear longitudinal beam assembly, a connecting end plate, a rear panel and a rear trailer assembly, wherein the rear trailer assembly and the rear longitudinal beam assembly are respectively arranged on both sides of the rear panel, the rear trailer assembly is connected to the connecting end plate, and the connecting end plate is axially connected to the rear longitudinal beam assembly, so that the drag force exerted on the rear trailer assembly can be transmitted to the rear longitudinal beam assembly through the connecting end plate. In addition, two connecting beams are arranged on the cross beam of the rear trailer assembly, and the connecting beams are connected to the rear longitudinal beam assembly, thereby increasing the radial connection between the rear trailer assembly and the rear longitudinal beam assembly, further dispersing the drag force exerted on the cross beam to the rear longitudinal beam assembly, thereby increasing the weight that the vehicle can tow, and reducing the damage to the vehicle body caused by the drag force.

[0055] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings:

[0056] It should be noted that the rear trailer mounting structure provided in the embodiment of the present application can be applied to a variety of different vehicles.

[0057] See also Figure 1 and Figure 2 As shown, the rear trailer mounting structure of the embodiment of the present application includes a rear longitudinal beam assembly 100, a connecting end plate 200, a rear panel 300 and a rear trailer assembly 400; the connecting end plate 200 is connected to the rear longitudinal beam assembly 100, the rear longitudinal beam assembly 100 and the rear trailer assembly 400 are respectively arranged on opposite sides of the rear panel 300, and the rear trailer assembly 400 is detachably connected to the connecting end plate 200; the rear trailer assembly 400 includes a cross beam 410 and two connecting beams 420 arranged on the cross beam 410, the connecting beam 420 sequentially passes through the rear panel 300 and the connecting end plate 200 and is detachably connected to the rear longitudinal beam assembly 100, and the cross beam 410 is used to be connected to the vehicle to be towed.

[0058] In the present application, the cross beam 410 of the rear trailer assembly 400 is connected to the vehicle to be towed, the rear trailer assembly 400 is connected to the connecting end plate 200, and the connecting end plate 200 is connected to the end of the rear longitudinal beam assembly 100, thereby installing the rear trailer assembly 400 on the vehicle, and the dragging force received by the rear trailer assembly 400 is transmitted to the rear longitudinal beam assembly 100 through the connecting end plate 200, and the rear longitudinal beam assembly 100 bears part of the dragging force, thereby increasing the towing weight of the rear trailer assembly 400.

[0059] Furthermore, the connecting beam 420 of the rear trailer assembly 400 is connected to the rear longitudinal beam assembly 100 through the rear panel 300 and the connecting end plate 200, so that a radial connection is added between the rear trailer assembly 400 and the rear longitudinal beam assembly 100, thereby transferring the drag force on the cross beam 410 to the rear longitudinal beam assembly 100 to a greater extent, further dispersing the force on the rear trailer assembly 400, increasing the drag force that the rear trailer assembly 400 can withstand, thereby increasing the weight of the towed vehicle that can be towed, and reducing the damage to the vehicle as a whole caused by the towing vehicle.

[0060] In addition, the rear trailer assembly 400 and the connecting end plate 200 as well as the connecting beam 420 and the rear longitudinal beam assembly 100 are all detachably connected. When there is no need to tow the vehicle, the rear trailer assembly 400 can be removed to reduce the weight of the vehicle itself and save the cost of vehicle driving.

[0061] In some possible implementations, see Figure 1 and Figure 2 As shown, the rear trailer assembly 400 of the embodiment of the present application also includes a first connecting plate 430, which is arranged around the connecting beam 420, and the connecting end plate 200 and the first connecting plate 430 are respectively located on two opposite sides of the rear panel 300, and the connecting end plate 200 and the first connecting plate 430 are detachably connected.

[0062] It can be understood that the first connecting plate 430 is arranged around the connecting beam 420. On the one hand, the first connecting plate 430 is detachably connected to the connecting end plate 200, so that the rear trailer assembly 400 is installed on the vehicle, and the dragging force on the cross beam 410 is transmitted to the rear longitudinal beam assembly 100 through the first connecting plate 430 and the connecting end plate 200; on the other hand, the first connecting plate 430 can also play a role in limiting the position of the connecting beam 420. When installing the rear trailer assembly 400, the connecting beam 420 is passed through the rear panel 300 and the connecting end plate 200 in sequence until the first connecting plate 430 abuts against the rear panel 300, thereby limiting the connecting beam 420 to a position suitable for connection with the rear longitudinal beam assembly 100, thereby improving the installation efficiency of the rear trailer assembly 400.

[0063] In some possible implementations, see Figure 2 , Figure 5 and Figure 6 As shown, the rear longitudinal beam assembly 100 of the embodiment of the present application includes a first beam body 110, a second beam body 120 and a side beam 130; the first beam body 110, the second beam body 120 and the side beam 130 are connected in sequence, and the first beam body 110, the second beam body 120 and the side beam 130 together form a accommodating cavity; the side beam 130 is used to be detachably connected to the part of the connecting beam 420 inserted into the accommodating cavity; the same end of the first beam body 110, the second beam body 120 and the side beam 130 is connected to the connecting end plate 200.

[0064] It should be noted that the first beam body 110, the second beam body 120 and the side beam 130 are connected together by welding, and the sides of the first beam body 110 and the second beam body 120 can be flanged to make the connection with the side beam 130 more stable. The specific connection method is not limited in this application. The side of the side beam 130 away from the accommodating cavity can be provided as follows: Figure 5 The mounting plate 131 shown is used to connect with other structures in the vehicle to fix the position of the rear longitudinal beam assembly 100 and improve the stability of the rear longitudinal beam assembly 100.

[0065] In addition, the portion of the connecting beam 420 inserted into the accommodating cavity is detachably connected to the side beam 130, so that the portion of the connecting beam 420 inserted into the accommodating cavity can be detachably connected to the side beam 130. Figure 6 As shown, the connecting beam 420 is cut along the diagonal line S, and a side connected to the side beam 130 is retained. In this way, it is convenient to set a connecting structure inside the connecting beam 420 to connect the connecting beam 420 to the side beam 130.

[0066] In some possible implementations, see Figure 2 , Figure 5 and Figure 6 As shown, a first avoidance hole 210 is opened on the connecting end plate 200 of the embodiment of the present application, a second avoidance hole 310 is opened on the rear panel 300, and the first avoidance hole 210 corresponds to the second avoidance hole 310, and the connecting beam 420 passes through the second avoidance hole 310 and the first avoidance hole 210 in sequence and is inserted into the accommodating cavity.

[0067] In a specific implementation, a first avoidance hole 210 and a second avoidance hole 310 are respectively opened on the connecting end plate 200 and the rear panel 300, and the connecting beam 420 can be inserted into the accommodating cavity through the second avoidance hole 310 and the first avoidance hole 210 to be connected to the side beam 130, thereby dispersing the force received by the rear trailer assembly 400 to the rear longitudinal beam assembly 100, thereby increasing the weight of the vehicle to be towed by the rear trailer assembly 400.

[0068] In some possible implementations, see Figures 2 to 5As shown, the embodiment of the present application also includes at least two first connecting members 500, one end of the first connecting member 500 is connected to the connecting end plate 200, and the first connecting member 500 is arranged on the peripheral side of the first avoidance hole 210; the first connecting member 500 passes through the connecting end plate 200 and the rear panel 300 in sequence and is connected to the first connecting plate 430.

[0069] In some embodiments, the first connector 500 is fixedly connected to the connecting end plate 200. The first connector 500 can be a projection welding stud. The projections of the projection welding stud are uniform in size and the projection welding points are precisely positioned, which is conducive to improving the stability of the connection between the first connector 500 and the connecting end plate 200. At least two first mounting holes 431 are provided on the first connecting plate 430. The first mounting holes 431 correspond to the first connector 500 one by one. When installing the rear trailer assembly 400, the stud passes through the rear panel 300, and the position of the rear trailer assembly 400 is adjusted so that the stud passes through the first mounting hole 431. The rear trailer assembly 400 can be installed on the vehicle by tightening the bolts on the side of the first connecting plate 430 away from the rear panel 300. The operation is convenient and is conducive to improving the installation efficiency of the rear trailer assembly. The specific structure of the first connector 500 is not limited in this application, as long as the connecting end plate 200 and the first connecting plate 430 can be detachably connected.

[0070] In some possible implementations, see Figure 3 and Figure 4 As shown, the rear longitudinal beam assembly 100 of the embodiment of the present application further includes a second connecting plate 140 , the first beam body 110 and the second beam body 120 are connected via the second connecting plate 140 , and the side of the second connecting plate 140 is connected to the connecting end plate 200 .

[0071] Specifically, the second connecting plate 140 can be U-shaped. By connecting the second connecting plate 140 with the first beam body 110 and the second beam body 120, on the one hand, the stability of the connection between the first beam body 110 and the second beam body 120 can be improved. On the other hand, the local thickness of the rear longitudinal beam assembly 100 can be increased, thereby improving the structural strength of the rear longitudinal beam assembly 100 and avoiding damage to the rear longitudinal beam assembly 100 caused by dragging force.

[0072] Furthermore, the second connecting plate 140 and the connecting end plate 200 can be welded by double-protection welding, which has small welding deformation and good crack resistance, and can further improve the stability of the connection between the rear longitudinal beam assembly 100 and the connecting end plate 200.

[0073] In some possible implementations, see Figure 4 and Figure 5 As shown, the rear longitudinal beam assembly 100 of the embodiment of the present application further includes a third connecting plate 150 , and the third connecting plate 150 connects the side beam 130 and the end plate 200 .

[0074] In a specific implementation, the third connecting plate 150 is L-shaped, and the third connecting plate 150 is connected to the connecting end plate 200 and the side beam 130. While strengthening the connection stability between the rear longitudinal beam assembly 100 and the connecting end plate 200, the thickness of the end of the side beam 130 can be further increased, and the structural strength of the rear longitudinal beam assembly 100 can be improved, thereby increasing the weight of the towed vehicle.

[0075] In some possible implementations, see Figure 4 , Figure 5 and Figure 6 As shown, the embodiment of the present application further includes a second connecting member (not shown in the figure), which passes through the third connecting plate 150, the side beam 130 and the connecting beam 420 in sequence to connect the side beam 130 and the connecting beam 420.

[0076] It should be noted that the third connecting plate 150 has a second mounting hole 151, the side beam 130 has a third mounting hole (not shown in the figure), the connecting beam 420 has a fourth mounting hole (not shown in the figure), and the second connecting member can be a bolt, and a connecting nut 421 matching the bolt is provided at the fourth mounting hole. After the rear trailer assembly 400 is fixed to the vehicle through the first connecting member 500, the second connecting member is sequentially passed through the second mounting hole 151, the third mounting hole and the fourth mounting hole to connect with the connecting nut 421, and the bolt is screwed to connect the connecting beam 420 to the side beam 130. In this way, the connecting beam 420 can be fastened from the side of the side beam 130 away from the accommodating cavity, which helps to improve the loading and unloading efficiency of the rear trailer assembly 400.

[0077] In some possible implementations, see Figure 1 As shown, the rear trailer assembly 400 of the embodiment of the present application further includes a trailer hook 440 , which is used to connect to the towed vehicle. The trailer hook 440 is disposed in the middle of the side of the cross beam 410 away from the rear panel 300 .

[0078] In some embodiments, the cross beam 410 is connected to the towed vehicle via a trailer hook 440. The trailer hook 440 is arranged in the middle of the cross beam 410 so that the dragging force can be evenly transmitted to the connecting beams 420 at both ends of the cross beam 410, and the dragging force can be evenly dispersed to the rear longitudinal beam assembly 100 via the connecting beams 420 and the connecting plates 430, thereby avoiding damage to the rear trailer assembly 400 and the vehicle caused by the dragging force and improving the load-bearing capacity of the rear trailer assembly 400.

[0079] See also Figure 1 As shown, an embodiment of the present application further provides a vehicle, comprising a vehicle body and any of the above-mentioned rear trailer mounting structures arranged on the vehicle body.

[0080] Among them, the structure and working principle of the rear trailer mounting structure are described in detail in the above embodiments, and will not be repeated here.

[0081] In the present application, the rear trailer assembly 400 of the rear trailer mounting structure is detachably connected to the rear longitudinal beam assembly 100. When the vehicle does not need to be towed, the rear trailer assembly 400 can be disassembled to reduce the vehicle's own weight and reduce the cost of vehicle travel. When the vehicle needs to be towed, the rear trailer assembly 400 is installed on the vehicle, the vehicle is towed through the trailer hook 440, and the towing force is transmitted to the rear longitudinal beam assembly 100 to avoid the towing force causing the vehicle body to deform and damage the vehicle.

[0082] In summary, the rear trailer installation structure of the present application connects the connecting beam 420 of the rear trailer assembly 400 to the side beam 130 of the rear longitudinal beam assembly 100 when it is necessary to tow a vehicle, and the first connecting plate 430 on the connecting beam 420 is connected to the connecting end plate 200, and the connecting end plate 200 is connected to the end of the rear longitudinal beam assembly 100, so that there are connection points in both axial and radial directions between the rear trailer assembly 400 and the rear longitudinal beam assembly 100, so that the dragging force exerted on the rear trailer assembly 400 can be transmitted to the rear longitudinal beam assembly 100 to a greater extent, and the rear longitudinal beam assembly 100 includes a second connecting plate 140 and a third connecting plate 150 to strengthen the structural strength of the rear longitudinal beam assembly 100, so that the rear longitudinal beam assembly 100 can withstand a greater dragging force, thereby increasing the towing weight of the rear trailer assembly 400 and reducing the possibility of damage to the vehicle body caused by the dragging force.
