The towing device may include a cross beam (e.g., a bumper beam) located at the front end or the rear end of the vehicle and a tow hook connected to the cross beam. The tow hook can be either near one end of the cross beam to align with a longitudinal frame member along the front-rear direction of the vehicle; in this way, the traction force applied by the towing vehicle is mainly transmitted to the longitudinal frame member.

It can be understood that these terms and coordinate axes are only used for simplifying the description and facilitating the clear description of the technical solution, and they do not constitute any limitation to the protection scope of the present application.

[0039] The present application provides a towing device. In one embodiment, as Figures 1 to 4As shown, the towing device includes a first plate 100, a second plate 200, and a cross beam 300. The first plate 100 is fixedly connected to the cross beam 300 and is used to fixedly connect the end of the longitudinal beam 401 of the vehicle frame. The second plate 200 includes a side plate 201 and a bottom plate 202. The side plate 201 is used to connect the side of the longitudinal beam 401, and the bottom plate 202 is used to connect the bottom of the longitudinal beam 401. The first end 2021 of the bottom plate 202 is connected to the first plate 100 and is separated from the longitudinal beam 401, so that a triangular space 101 is formed by the bottom plate 202, the first plate 100, and the longitudinal beam 401, as Figure 4 shown.

[0040] Compared with the prior art, the beneficial effect of the towing device provided by this embodiment is that the cross beam 300 is connected to the longitudinal beam 401 through the first plate 100 and the second plate 200, which improves the connection strength between the cross beam 300 and the longitudinal beam 401 at least from the following three aspects: First, the first plate 100 is connected to the end of the longitudinal beam 401, and the second plate 200 is connected to the side and bottom of the longitudinal beam 401, thus forming a multi-point connection. Second, the bottom plate 202 of the second plate 200 is inclined downward, and the first end 2021 of the bottom plate 202 is separated from the longitudinal beam 401, so that a triangular space is formed between the bottom surface of the longitudinal beam 401, the bottom plate 202, and the first plate 100; that is to say, overall, the lower part of the longitudinal beam 401, the bottom plate 202, and the first plate 100 form a triangular structure, thereby improving the connection strength between the cross beam 300 and the longitudinal beam 401 by using the stability of the triangle. Third, the triangular space, as a cavity structure, is superposed with the longitudinal beam cavity 4011 (the longitudinal beam 401 is generally a hollow structure) in the Z direction, forming a cavity reinforcement, thereby improving the connection strength between the cross beam 300 and the longitudinal beam 401.

[0041] Exemplarily, as Figure 4 shown, the connection between the bottom plate 202 and the bottom of the longitudinal beam 401, and the connection between the first end 2021 of the bottom plate 202 and the first plate 100 can both be realized by bolts. Exemplarily, as Figure 3 shown, the connection between the side plate 201 and the side of the longitudinal beam 401 can also be realized by bolts.

[0042] Exemplarily, a end plate perpendicular to the longitudinal beam 401 can be fixedly arranged at the top of the longitudinal beam 401, and the first plate 100 can be fixedly connected to the end plate by bolts, so as to realize the fixed connection with the end of the longitudinal beam 401, as Figure 4 shown.

[0043] In this embodiment, the connection between the first plate 100 and the end of the longitudinal beam 401 mainly realizes the relative fixation of the cross beam 300 and the longitudinal beam 401 in the X direction. The connection between the side plate 201 and the side of the longitudinal beam 401 mainly realizes the relative fixation of the cross beam 300 and the longitudinal beam 401 in the Y direction. The connection between the bottom plate 202 and the bottom of the longitudinal beam 401 mainly realizes the relative fixation of the cross beam 300 and the longitudinal beam 401 in the Z direction. In this way, the cross beam 300 and the longitudinal beam 401 are relatively fixed in all three directions of X, Y, and Z, and the connection force can be generated by the tensile strength (rather than the shear strength) of the bolt, thus greatly improving the connection strength.

[0044] In this embodiment, the first plate 100 may be a flat plate structure. Exemplarily, a flat plate portion that fits with the first plate 100 is provided at the first end 2021 of the bottom plate 202.

[0045] Exemplarily, the side plate 201 and the bottom plate 202 of the second plate 200 are of an integral structure.

[0046] Exemplarily, the longitudinal beam 400 connected to the cross beam 300 may include an upper plate, an upper plate reinforcement plate, a lower plate, a lower plate reinforcement plate, a lower plate strengthening plate, and so on.

[0047] It is easy to understand that generally, in this embodiment, the number of the first plates 100 and the second plates 200 is two each. They are divided into two groups and are respectively arranged at both ends of the cross beam 300. Among them, each group includes one first plate 100 and one second plate 200.

[0048] In this embodiment, the cross beam 300 may be a crash beam, especially a rear crash beam, so as to realize the effective integration of the towing device and the crash beam, enable the towing device to have the towing function while taking into account the safety collision performance of the crash beam, and can be used as an upgrade of the vehicle end anti-collision performance structure.

[0049] In this embodiment, the application scenarios of the towing device are not limited. For example, it can be applied to the front end of the vehicle or the rear end of the vehicle. It can be applied to the case where the trailer hitch is located on one side of the cross beam or the case where the trailer hitch is located in the middle of the cross beam.

[0050] In a possible embodiment, as Figure 1 and Figure 4 shown, the second end 2022 of the bottom plate 202 of the second plate 200 is attached to and connected to the bottom of the longitudinal beam 401. The second plate 200 is provided with a side connection portion 203 extending towards the first plate 100, and the side connection portion 203 is fixedly connected to the first plate 100.

[0051] This embodiment provides a connection method between the bottom plate 202 and the longitudinal beam 401, that is, the bottom of the longitudinal beam 401 is connected through the flat second end 2022. The second end 2022 and the first end 2021 are the two ends of the bottom plate 202 that are far away from each other.

[0052] In this embodiment, the second plate 200 is provided with a side connection portion 203, so that on the basis of being connected to the first plate 100 through the first end 2021, the first plate 100 is connected again through the side connection portion 203, forming a multi-point connection, thereby improving the connection strength between the first plate 100 and the second plate 200, and further improving the connection strength between the cross beam 300 and the longitudinal beam 401.

[0053] In a possible embodiment, the first plate 100 is provided with a tilted portion 102, which is fixedly connected to a side connection portion 203 of the second plate 200, and the side connection portion 203 and the tilted portion 102 are both inclined toward the outside of the vehicle, forming an angle between the tilted portion 102 and the first plate 100.

[0054] This embodiment provides a connection method between the side connection portion 203 of the second plate 200 and the first plate 100 , that is, the connection is made through the tilting portion 102 .

[0055] The tilting portion 102 and the side connection portion 203 are both inclined toward the outside of the vehicle. Specifically, when the towing device is applied to the front end of the vehicle, the tilting portion 102 and the side connection portion 203 are both extended toward the front and outside of the vehicle; when the towing device is applied to the rear end of the vehicle, they are both extended toward the rear and outside of the vehicle.

[0056] There is an angle between the tilting portion 102 and the first plate 100 . Exemplarily, the two are an integrated structure.

[0057] In one possible implementation, Figure 4 As shown, the first plate 100 and the longitudinal beam 401 are fixedly connected to the vehicle body panel 402 , and the vehicle body panel 402 is sandwiched between the first plate 100 and the end of the longitudinal beam 401 .

[0058] In one example of this embodiment, Figure 4 As shown, the vehicle body panel 402 may include a rear panel inner panel 4021 and a rear panel outer panel 4022 , which enclose a rear panel cavity 4023 at the upper portion, and whose lower portion is a flat plate structure inserted between the first plate 100 and the end of the longitudinal beam 401 .

[0059] In this embodiment, after the triangular space 101 and the longitudinal beam cavity 4011 are superimposed in the Z direction to form a high-strength cavity reinforcement, the superimposed reinforced cavity and the rear enclosure inner and outer panels intersect at the end of the longitudinal beam 401, and the rear enclosure cavity 4023 is connected to the load through the overlapping area of the rear enclosure inner and outer panels. The corresponding drag force transmission diagram of this embodiment is shown in FIG. Figure 7 As shown, the arrows in the figure indicate the transmission path of the drag force.

[0060] In one possible implementation, Figure 1 , Figure 2 andFigure 5 As shown in the figure, the first plate 100 is connected to the cross beam 300 through two third plates 500. The two third plates 500 are arranged at intervals and are located between the first plate 100 and the cross beam 300. The third plate 500 is perpendicular to the extension directions of the first plate 100 and the cross beam 300. The first plate 100, the two third plates 500 and the cross beam 300 enclose a rectangular space 501, as Figure 6 shown in the figure.

[0061] Based on the triangular space 101, the longitudinal beam cavity 4011 and the rear enclosure cavity 4023 in this embodiment (see Figure 4 ), a rectangular space 501 is further provided. The longitudinal beam cavity 4011, the triangular space 101 and the rear enclosure cavity 4023 are connected to the cross beam 300 which is also a hollow structure with a cavity through the rectangular space 501 formed by the third plate 500 in the X direction, achieving the effect of multi-cavity superposition and combined force bearing, thereby improving the connection strength between the cross beam 300 and the longitudinal beam 401, enabling the towing force to be successfully transmitted to the vehicle and allowing the vehicle to get out of trouble smoothly.

[0062] In a possible embodiment, as Figure 4 and Figure 5 shown, one end of the third plate 500 is connected to the first plate 100, and the other end is provided with a first opening groove 502. The cross beam 300 is located in the first opening groove 502 and fits against the inner wall of the first opening groove 502. Figure 4 In the figure, the thick solid line represents the inner wall of the first opening groove 502.

[0063] Specifically, as Figure 4 and Figure 5 shown, when the cross section of the cross beam 300 is rectangular, the first opening groove 502 is also rectangular; in this way, the first opening groove 502 can cover three surfaces of the cross beam 300, thereby increasing the contact length between the first opening groove 502 and the cross beam 300 and improving the connection strength between the two, especially when the edge of the first opening groove 502 is welded to the cross beam 300.

[0064] Generally, as Figure 5 shown, the cross beam 300 is horizontally arranged, the third plate 500 is vertically arranged and perpendicular to the cross beam 300; the first plate 100 is vertically arranged and perpendicular to the third plate 500, and the side plates of the second plate 200 are vertically arranged and substantially perpendicular to the first plate 100.

[0065] In a possible embodiment, as Figures 1 to 3 shown, the towing device provided in this application further includes a trailer hitch assembly 600. The trailer hitch assembly 600 is connected to the middle of the cross beam 300 through a fourth plate 700; the fourth plate 700 is L-shaped, the upper part of the fourth plate 700 is connected to the cross beam 300, and the trailer hitch assembly 600 is connected to the lower part of the fourth plate 700.

[0066] In this embodiment, the trailer hitch assembly 600 is arranged in the middle of the cross beam 300. Compared with being arranged on one side of the cross beam, arranging it in the middle enables the towing force generated by the towing vehicle to be transmitted to the two longitudinal beams of the vehicle, providing good stability during towing and better adapting to various scenarios such as mud rescue and RV towing.

[0067] The schematic diagram of the towing force transmission corresponding to this embodiment is as Figure 11 shown. The arrows in the figure indicate the transmission path of the towing force. When towing the whole vehicle, the towing force is sequentially transmitted through the trailer hitch assembly 600 to the fourth plate 700, the cross beam 300, and the third plate 500. The third plate 500 is firmly connected to the frame longitudinal beam 401 and the body panel 402 through the first plate 100 and the second plate 200, and the towing force drives the frame longitudinal beam 401 and the body panel 402 to transmit the force synchronously. During the towing process, the longitudinal beam cavity 4011, the triangular space 101, and the rear enclosure cavity 4023 cooperate to bear the force, realizing the structural advantages of high bearing strength, safety, and stability.

[0068] In this embodiment, the trailer hitch assembly 600 is connected to the cross beam 300 through the L-shaped fourth plate 700. Most of the fourth plate 700 is located below the cross beam 300, and the trailer hitch assembly 600 is basically connected to the lowermost end of the fourth plate 700, thereby forming an avoidance space 701 to provide space for the installation of vehicle components such as the bumper, as Figure 8 shown.

[0069] In a possible embodiment, as Figure 9 shown, the number of the fourth plates 700 is two. The two fourth plates 700 are arranged at intervals and perpendicular to the extension direction of the cross beam 300; a second opening groove 702 is provided in the upper part of the fourth plate 700 ( Figure 9 The thick solid line in it shows a part of it, and the other parts are located below the cross beam and are blocked by the cross beam and cannot be seen), and the cross beam 300 is located in the second opening groove 702 and fits against the inner wall of the second opening groove 702.

[0070] The further limitation of the fourth plate 700 in this embodiment helps to improve the connection strength of the fourth plate 700, so that the trailer hitch assembly 600 is more stably connected to the cross beam 300.

[0071] The shape of the second opening groove 702 is not limited in this embodiment. It can be understood that the shape of the second opening groove 702 matches the cross-sectional shape of the cross beam 300. When the cross-section of the cross beam 300 is rectangular, as Figure 9 shown, the shape of the second opening groove 702 is also rectangular.

[0072] In a possible implementation, the trailer hitch assembly 600 includes a ball pin 601 and a telescopic rod 603. A horizontal sleeve 800 is provided at the lower part of the fourth plate 700. The first end of the telescopic rod 603 is inserted into the horizontal sleeve 800, the second end extends out of the horizontal sleeve 800 and is provided with a ball pin 601, and the length of the second end of the telescopic rod 603 extending out of the horizontal sleeve 800 is adjustable.

[0073] In this implementation, the length of the end of the telescopic rod 603 provided with the ball pin 601 extending out of the horizontal sleeve 800 is adjustable, so as to realize the platform application of the trailer part; that is, for different vehicle models produced on the same platform, by adjusting the extending length of the telescopic rod 603, the horizontal dimension of the avoidance space 701 can be adjusted, so as to meet the requirements of different vehicle models for different sizes of avoidance spaces. In addition, when there is no towing requirement, the trailer hitch assembly 600 can be not installed during vehicle production, and at this time, the towing device can perform the function of a conventional anti-collision beam.

[0074] Specifically, as Figure 10 shown, the adjustable length of the telescopic rod 603 extending out of the horizontal sleeve 800 can be achieved in the following way. The telescopic rod 603 is slidably arranged inside the horizontal sleeve 800. At least two first pin holes 6031 ( Figure 10 in this case, the number of the first pin holes 6031 is two) are provided on the telescopic rod 603, and a second pin hole is provided on the horizontal sleeve 800. When different first pin holes 6031 are aligned with the second pin hole, the length of the telescopic rod 603 extending out of the horizontal sleeve 800 is different. After adjusting the telescopic rod 603 to the required extending length, the telescopic rod 603 can be locked by using a locking pin 801.

[0075] Specifically, the telescopic rod 603 can be a hollow square tube, which has the characteristics of high bending and torsion resistance and light weight, and can bear a greater towing force. The relative sliding between the telescopic rod 603 and the horizontal sleeve 800 can be achieved by clearance fit, and the designed clearance is 0.5 mm to meet the assembly passability and avoid large loose connection noises generated by the telescopic rod 603 during towing. Specifically, the X-direction telescopic stroke of the telescopic rod 603 can be 245 mm, the accommodation stroke of the horizontal sleeve 800 can be 195 mm, and the telescopic reserve is 50 mm.

[0076] In this implementation, the horizontal sleeve 800 is clamped between two fourth plates 700 and can be fixedly connected to the fourth plates 700 by welding.

[0077] Exemplarily, in addition to the ball pin 601 and the telescopic rod 603, the trailer hitch assembly may further include an intermediate connecting member 602, as Figure 9 shown. The ball pin 601 and the telescopic rod 603 are connected into one body through the intermediate connecting member 602.

[0078] The present application also provides a vehicle, which is provided with the above-mentioned towing device. Therefore, the cross beam of the towing device and the longitudinal beam of the vehicle frame have good connection strength, and the towing force for towing the vehicle can be smoothly transmitted to the vehicle frame and body of the vehicle, thereby realizing the towing of the vehicle.

[0079] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
