[0029] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0030] Reference below Figure 1-Figure 4 A connection assembly 100 for a vehicle according to an embodiment of the present invention is described, and the connection assembly 100 for a vehicle can be applied to a vehicle.

[0031] Combination Figure 1-Figure 4As shown, the vehicle connection assembly 100 according to the present invention may mainly include: a vehicle frame rear cross beam 10 , a towing assembly 20 and a towing hook 30 .

[0032] Among them, the rear cross beam 10 of the frame is extended in the left and right direction, and the towing assembly 20 includes: a connecting column 21, a towing arm 22 and a towing ball head 23. The connecting column 21 is extended in the front-to-back direction and is connected to the rear cross beam 10 of the frame. One end of the towing arm 22 is connected to the end of the connecting column 21 away from the rear cross beam 10 of the frame, and the other end of the towing arm 22 is inclined downward and extends backward. The towing ball head 23 is arranged at the other end of the towing arm 22. The towing hook 30 is extended in the front-to-back direction. The towing hook 30 is detachably connected to at least one of the connecting column 21 and the towing arm 22. A towing hole 321 is opened at the end of the towing hook 30 away from the rear cross beam 10 of the frame, and the towing hole 321 is located above the towing ball head 23 and in front of the towing ball head 23.

[0033] Specifically, by setting the connecting column 21 along the front-to-back direction, one end of the towing arm 22 is connected to the end of the connecting column 21 away from the rear cross beam 10 of the frame, and the other end of the towing arm 22 is inclined downward and extends rearward, and the towing ball head 23 is set at the other end of the towing arm 22. In this way, the basic structure of the towing assembly 20 can be formed. After the front end of the connecting column 21 is connected to the rear cross beam 10 of the frame, the towing assembly 20 as a whole can be located on the rear side of the rear cross beam 10 of the frame, and the towing ball head 23 is located on the rear lower side of the rear cross beam 10 of the frame. The towing ball head 23 can be connected to the towing end of a bicycle trailer, a motorcycle trailer or a motorhome waiting to be towed, thereby realizing the towing function of the vehicle.

[0034] In addition to the towing function of the vehicle, the vehicle also needs to be towed out of trouble. In the prior art, the vehicle needs to be equipped with a corresponding towing assembly. In actual applications, compared with using the towing assembly to tow out of trouble, users often use the towing ball head 23 visible at the rear end to tow out of trouble. Since the towing ball head 23 is located at a low position and has a large horizontal height from the rear cross beam 10 of the frame, there is a large lever arm, which is prone to failure, thereby posing a safety hazard.

[0035] In the present application, by providing a towing hook 30 extending in the front-rear direction, the towing hook 30 is detachably connected to at least one of the connecting column 21 and the towing arm 22, and a towing hole 321 is provided at one end of the towing hook 30 away from the rear cross beam 10 of the frame. At this time, the end of the towing hook 30 away from the rear cross beam 10 of the frame is located above the towing ball head 23 and at the front side of the towing ball head 23. In this way, the towing hook 30 has a towing function while ensuring that it will not interfere with the towing vehicle and that the towing ball head 23 and even the connecting assembly 100 of the vehicle can normally perform the towing function.

[0036] Specifically, on the one hand, the towing hole 321 can be used for a towing hook or a towing rope to be inserted, which is convenient for towing and realizes the towing function, thereby avoiding the need to provide an additional towing hook 30 on the frame, realizing the integration of the towing function and the towing function, and shortening the towing arm to improve the towing capacity, thereby facilitating the user to choose to use the towing function or the towing function of the vehicle's connection assembly 100 according to usage requirements, thereby avoiding failure of the vehicle's connection assembly 100 and avoiding safety hazards.

[0037] On the other hand, when the vehicle connection assembly 100 performs the towing function, the towing hole 321 can also be used for the safety chain to pass through, providing towing safety protection, thereby reducing the setting of the safety chain hanging hole 121 in the towing component 20 and simplifying the structure of the towing component 20.

[0038] In addition, through the detachable design of the towing hook 30 and the towing assembly 20, the towing hook 30 can be removed and installed on the front side of the vehicle body when needed, so that the towing hook 30 can be shared at the front and rear of the vehicle body, which can reduce the cost and weight of the vehicle.

[0039] Therefore, by detachably connecting the towing hook 30 extending forward and backward to at least one of the connecting column 21 and the towing arm 22, the end of the towing hook 30 away from the rear cross beam 10 of the frame is located above the towing ball head 23 and in front of the towing ball head 23, and a towing hole 321 is provided at the end of the towing hook 30 away from the rear cross beam 10 of the frame, which can not only realize the integration of towing function and traction function, improve the traction capacity, and facilitate user use, but also simplify the structure of the towing component 20 and even the vehicle, thereby reducing cost and weight.

[0040] Combination Figure 1-Figure 4 As shown, the towing hook 30 may include a connecting portion 31 and a towing portion 32, the connecting portion 31 is extended in the front-to-back direction, the towing portion 32 is connected to the connecting portion 31 in the front-to-back direction and is provided with a towing hole 321, the outer periphery of the connecting portion 31 is provided with a first threaded portion (not shown in the figure), the connecting column 21 and the towing arm 22 are provided with a mounting hole 24, the mounting hole 24 extends in the front-to-back direction and the inner wall is provided with a second threaded portion (not shown in the figure), and the first threaded portion and the second threaded portion are detachably threadedly matched.

[0041] Specifically, by providing a first threaded portion on the periphery of the connecting portion 31 and providing a second threaded portion inside the mounting hole 24, the connection between the towing hook 30 and the towing component 20 can be fixed only by gradually screwing the connecting portion 31 into the mounting hole 24 so that the first threaded portion and the second threaded portion are threadedly engaged with each other. Moreover, the towing hook 30 can be removed from the towing component 20 only by gradually screwing the connecting portion 31 out of the mounting hole 24 and releasing the threaded engagement between the first threaded portion and the second threaded portion. This not only improves the connection stability between the towing hook 30 and the towing component 20, but also makes the assembly and disassembly of the towing hook 30 simpler and more convenient.

[0042] It should be noted that since the towing component 20 is a solid steel structure with a very strong structure, after the mounting holes 24 are provided on the connecting column 21 and the towing arm 22, the towing component 20 can still meet its structural strength requirements and ensure the reliability of the vehicle connection assembly 100.

[0043] In addition, considering that the connecting column 21 and the trailing arm 22 are mostly connected by welding, the connecting portion 31 of the towing hook 30 of the present application is threadedly matched with the trailing arm 22 and the connecting column 21 at the same time. This can also enhance the connection stability and reliability between the connecting column 21 and the trailing arm 22, thereby preventing the vehicle's connection assembly 100 from being damaged or even failing due to low structural strength during operation, thereby improving the reliability of the vehicle's connection assembly 100.

[0044] Combination Figure 1 and Figure 4 As shown, the axis of the mounting hole 24 coincides with the axis of the connecting column 21. Specifically, the connecting column 21 is extended in the front-to-back direction, and the axis of the connecting column 21 is located in the same horizontal plane as the rear cross beam 10 of the frame. The mounting hole 24 is extended in the front-to-back direction. By coinciding the axis of the mounting hole 24 with the axis of the connecting column 21, it can be ensured that the mounting hole 24 and the rear cross beam 10 of the frame are located in the same horizontal plane, so that the towing hook 30 and the rear cross beam 10 of the frame are located in the same horizontal plane. When the towing function of the vehicle is exerted, the towing point is horizontally coincident with the rear cross beam 10 of the frame, which can make the lever arm as short as possible, thereby better improving the towing capacity.

[0045] Combination Figure 4 As shown, one end of the connecting portion 31 away from the pulling portion 32 is connected to an elastic member 33 , which is disposed in the mounting hole 24 , and the other end of the elastic member 33 selectively abuts against the inner wall of the mounting hole 24 in the front-to-back direction.

[0046] Specifically, by connecting the elastic member 33 at one end of the connecting portion 31 away from the traction portion 32, when the connecting portion 31 is extended into the mounting hole 24, the elastic member 33 can also be extended into the mounting hole 24, and as the connecting portion 31 is gradually extended, the other end of the elastic member 33 can abut against the inner wall of the mounting hole 24 in the front-to-back direction, and the elastic member 33 is compressed and deformed and applies a backward elastic force to the connecting portion 31, which can provide a pre-tightening force for the threaded connection between the connecting portion 31 and the connecting column 21, thereby improving the connection stability and reliability between the traction hook 30 and the towing component 20, and improving the reliability of the vehicle connection assembly 100.

[0047] Combination Figure 1-Figure 4 As shown, the vehicle connection assembly 100 may also include: a first connecting pin 40, a first through hole 311 is provided on the connecting portion 31, a second through hole 211 is provided on the connecting column 21, the first through hole 311 and the second through hole 211 correspond to each other, and the first connecting pin 40 is penetrated by the first through hole 311 and the second through hole 211.

[0048] Specifically, by providing a first through hole 311 on the connecting portion 31 and a second through hole 211 on the connecting column 21, when the connecting portion 31 gradually extends into the mounting hole 24 in the connecting column 21, the first through hole 311 and the second through hole 211 can be made to correspond to each other, so that the user can be prompted that the correct assembly position has been reached. Then, the first connecting pin 40 is passed through the first through hole 311 and the second through hole 211, so that the first connecting pin 40 can also connect the connecting column 21 and the connecting portion 31, and the connection strength between the connecting column 21 and the connecting portion 31 can be strengthened, that is, without affecting the detachable setting of the towing hook 30, the connection strength between the towing hook 30 and the towing component 20 can be further strengthened, and the structural reliability of the vehicle connection assembly 100 can be improved.

[0049] Combination Figure 1-Figure 4 As shown, a first guide portion 312 is provided on the side of the connecting portion 31 away from the traction portion 32, and a second guide portion 221 is provided on the side of the dragging arm 22 away from the connecting column 21. The second guide portion 221 is located on the circumferential outer side of the mounting hole 24, and the first guide portion 312 and the second guide portion 221 are guided and matched in the front-to-back direction.

[0050] Specifically, during assembly, the connecting portion 31 needs to be extended into the mounting hole 24 from the back to the front, so that the side of the connecting portion 31 away from the traction portion 32 will first approach the rear side of the mounting hole 24, and the rear side of the mounting hole 24 is the side of the dragging arm 22 away from the connecting column 21 in the front-to-back direction. By providing a first guide portion 312 on the side of the connecting portion 31 away from the traction portion 32, and providing a second guide portion 221 on the side of the dragging arm 22 away from the connecting column 21, when the connecting portion 31 is extended into the mounting hole 24, the first guide portion 312 and the second guide portion 221 can be guided and matched in the front-to-back direction, so that the connecting portion 31 can be extended into the mounting hole 24 more quickly and accurately, thereby improving the assembly efficiency of the vehicle connection assembly 100, making the assembly of the vehicle connection assembly 100 simpler and more convenient, and enhancing the user experience.

[0051] In some embodiments of the utility model, as shown in the figure, at least one of the first guide portion 312 and the second guide portion 221 can be set as a guiding slope, which can not only make the structure of the first guide portion 312 and the second guide portion 221 simpler, but also make the guiding cooperation between the first guide portion 312 and the second guide portion 221 more stable and smooth.

[0052] Of course, at least one of the first guide portion 312 and the second guide portion 221 may also be an arc-shaped surface, which is not specifically limited here.

[0053] Combination Figure 1-Figure 4 As shown, the vehicle connection assembly 100 may further include: a second connecting pin 50, a third through hole 212 is provided on the connecting column 21, a towing mounting member 11 is provided on the rear cross beam 10 of the frame, the towing mounting member 11 is provided with a mounting groove 111 and a fourth through hole 112, the mounting groove 111 is extended in the front-rear direction, the connecting column 21 is provided in the mounting groove 111 and the third through hole 212 corresponds to the fourth through hole 112, and the second connecting pin 50 is penetrated by the third through hole 212 and the fourth through hole 112.

[0054] Specifically, by setting a third through hole 212 on the connecting column 21, and opening a mounting groove 111 and a fourth through hole 112 on the towing mounting member 11, and the mounting groove 111 is extended in the front-to-back direction, so that during assembly, the connecting column 21 can be first inserted into the mounting groove 111 until the third through hole 212 and the fourth through hole 112 correspond to each other, and then the second connecting pin 50 is passed through the third through hole 212 and the fourth through hole 112, and a fixing clip 51 is set on the second connecting pin 50, so as to realize the connection between the connecting column 21 and the towing mounting member 11, that is, to realize the connection between the towing component 20 and the rear cross beam 10 of the frame, so that the connection between the towing component 20 and the rear cross beam 10 of the frame can be made simpler and more convenient.

[0055] It should be noted that the third through hole 212 can be spaced in front of the first through hole 311, and the first through hole 311 and the towing mounting member 11 can be spaced in the front-to-rear direction, so that the connection between the towing component 20 and the rear cross beam 10 of the frame and the connection between the towing hook 30 and the towing component 20 can be independent of each other, thereby making it convenient for users to disassemble and assemble the towing hook 30.

[0056] Combination Figure 1 and Figure 2 As shown, the towing mounting member 11 is further provided with a safety plate 12, and a safety chain hanging hole 121 is provided on the safety plate 12. In this way, when the vehicle connection assembly 100 performs the towing function, even if the towing hook 30 is removed, the safety chain can be connected through the safety chain hanging hole 121, so that when the coordination between the towing ball head 23 and the towed vehicle fails, the safety chain can also connect the vehicle connection assembly 100 with the towed vehicle, providing towing safety protection and improving the reliability of the vehicle connection assembly 100.
