[0038] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0039] Embodiment 1

[0040] This embodiment relates to an anti-collision beam assembly, which can reduce the installation height of the trailer hitch, thereby improving the stress state of the anti-collision beam assembly during towing; an exemplary structure of the anti-collision beam assembly is as shown in Figure 1 、 Figure 2 and Figure 3 shown.

[0041] Generally speaking, the anti-collision beam assembly includes an anti-collision beam body 1, a mounting bracket 3 provided on the anti-collision beam body 1, and a trailer hitch mounting sleeve 4 for mounting the trailer hitch; the mounting bracket 3 includes an upper connecting portion fixedly connected to the anti-collision beam body 1 and a lower connecting portion located below the anti-collision beam body 1, and the trailer hitch mounting sleeve 4 is arranged on the lower connecting portion.

[0042] It should be noted that based on the above overall design concept, the technical solutions of the present utility model can adopt a variety of different specific implementation structures, forms or configuration sequences. For example, the above anti-collision beam assembly can be applied to the front anti-collision beam or the rear anti-collision beam, that is, the above anti-collision beam body 1 can be the body of the front anti-collision beam or the rear anti-collision beam; when the anti-collision beam assembly is applied to the front anti-collision beam, it is used for being towed by a rescue vehicle when a trapped vehicle is to be rescued; when the anti-collision beam assembly is applied to the rear anti-collision beam, the vehicle is used as a rescue vehicle to tow a trapped vehicle. For the specific structure and assembly of the mounting bracket 3, of course, a variety of different specific structural forms can be flexibly adjusted. For parts required for the implementation of the overall solution but not involved in the above overall setting, reasonable and flexible design can be made with reference to mature setting means in the art, the actual situation during implementation, etc. The following specific implementation solutions of this embodiment are only one of the relatively better ones among the many solutions that can be formed by the above various combinations and their variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements in combination with the actual situation. Obviously, the many solutions that can be formed by the above various specific form combinations and their variations, as well as the specific implementation solutions of this embodiment, are all within the protection scope of the present utility model.

[0043] Specifically, in this embodiment, as shown in Figure 2As shown in the figure, the mounting bracket 3 includes a front mounting plate 31 and a rear mounting plate 32 respectively disposed on the front and rear sides of the anti-collision beam body 1, and both the front mounting plate 31 and the rear mounting plate 32 include an upper plate body 300 and a lower plate body 301 that are integrally connected up and down. Among them, the two upper plate bodies 300 belonging to the front mounting plate 31 and the rear mounting plate 32 constitute the upper connecting portion, and the two lower plate bodies 301 belonging to the front mounting plate 31 and the rear mounting plate 32 constitute the lower connecting portion. The upper plate bodies 300 of the front mounting plate 31 and the rear mounting plate 32 are respectively lapped on the front and rear sides of the anti-collision beam body 1. The mounting bracket 3 uses the front mounting plate 31 and the rear mounting plate 32, which are respectively lapped on the front and rear sides of the anti-collision beam body 1. The trailer hitch mounting sleeve 4 can be simultaneously connected to the lower plate bodies 301 of the front mounting plate 31 and the rear mounting plate 32. The trailer hitch mounting sleeve 4 can transmit the towing force to the anti-collision beam body 1 through the front mounting plate 31 and the rear mounting plate 32 respectively, which is beneficial to the dispersed transmission of the force between the trailer hitch and the anti-collision beam body 1, thereby enriching the force transmission path, improving the force transmission effect, and further enhancing the structural stability and force transmission performance of the mounting bracket 3.

[0044] In addition, as Figure 2 and Figure 3 , Figure 4 shown in the figure, the anti-collision beam assembly of this embodiment further includes energy-absorbing boxes 2 respectively connected between the body side rails on both sides and the anti-collision beam body 1. The mounting bracket 3 of this embodiment is disposed at the portion of the anti-collision beam body 1 connected to a certain energy-absorbing box 2, and the upper plate body 300 of the rear mounting plate 32 is clamped between the anti-collision beam body 1 and the energy-absorbing box 2. That is, the mounting bracket 3 can be disposed at the energy-absorbing box 2 on the left side of the vehicle, or at the energy-absorbing box 2 on the right side of the vehicle. By disposing the mounting bracket 3 at the position where the energy-absorbing box 2 is located, and clamping the upper plate body 300 of the rear mounting plate 32 between the energy-absorbing box 2 and the anti-collision beam body 1, the connection firmness of the rear mounting plate 32 on the anti-collision beam body 1 can be improved, and further the structural stability of the mounting bracket 3 can be enhanced.

[0045] Regarding the specific installation method of the mounting bracket 3 on the anti-collision beam body 1, of course, there are many different structural schemes to choose from. In this embodiment, as Figure 5 , Figure 6 and Figure 7 shown in the figure, the energy-absorbing box 2 includes an energy-absorbing box body 21 and an end plate 20 disposed at the front end of the energy-absorbing box body 21. The upper plate body 300 of the rear mounting plate 32 is clamped between the anti-collision beam body 1 and the end plate 20. The energy-absorbing box 2, the anti-collision beam body 1 and the mounting bracket 3 are integrally fixed by fasteners sequentially passing through the upper plate body 300 of the front mounting plate 31, the anti-collision beam body 1, the upper plate body 300 of the rear mounting plate 32, and the end plate 20. By using fasteners to sequentially pass through the front mounting plate 31, the anti-collision beam body 1, the rear mounting plate 32 and the end plate 20, the connection and fixation of the mounting bracket 3, the anti-collision beam body 1 and the energy-absorbing box 2 are realized, which is not only convenient and efficient in the assembly method, but also reliable in the connection performance.

[0046] Specifically, a plurality of connection holes 200 are provided on the end plate 20 of this embodiment. Corresponding to each connection hole 200, a plurality of mounting holes 302 are provided on the upper plate bodies 300 of the front mounting plate 31 and the rear mounting plate 32. A plurality of through holes 10 are provided on the anti-collision beam body 1. The above-mentioned fasteners include multiple sets of bolt pairs 5 provided according to the number of the connection holes 200. Four sets of bolt pairs 5 are provided in this embodiment, that is, two connection holes 200 are provided on each of the left and right sides of the end plate 20. Correspondingly, four through holes 10 are provided on the anti-collision beam body 1, and four mounting holes 302 are also provided on each of the upper plate bodies 300 of the front mounting plate 31 and the rear mounting plate 32. The bolts of the four bolt pairs 5 are respectively passed through the corresponding mounting holes 302, through holes 10 and connection holes 200, pass through the cavity 100 of the anti-collision beam body 1, and finally pass to the rear side of the end plate 20 and are screwed into the matching nuts, so that the anti-collision beam body 1, the mounting bracket 3 and the end plate 20 can be locked into one body. The anti-collision beam body 1, the energy absorption box 2 and the mounting bracket 3 are screwed and fixed by multiple bolt pairs 5, which greatly improves the maintenance convenience and economy of the vehicle, and has high maintenance convenience and maintenance economy. The anti-collision beam body 1, the mounting bracket 3 or the energy absorption box 2 can be conveniently disassembled and replaced separately.

[0047] In addition to being screwed and fixed by the bolt pairs 5, the anti-collision beam body 1 of this embodiment is welded and fixed between the two upper plate bodies 300 belonging to the front mounting plate 31 and the rear mounting plate 32, and between the trailer hitch mounting sleeve 4 and the two lower plate bodies 301 belonging to the front mounting plate 31 and the rear mounting plate 32. Welding the front mounting plate 31 and the rear mounting plate 32 to the anti-collision beam body 1 can further improve the connection reliability between the mounting bracket 3 and the anti-collision beam body 1. The trailer hitch mounting sleeve 4 and the front mounting plate 31 and the rear mounting plate 32 are fixed by welding. Not only the connection performance is reliable, but also the structure is easy to implement, and the front mounting plate 31, the rear mounting plate 32 and the trailer hitch mounting sleeve 4 can be reliably welded into a firm whole. For the above two welds, conventional welding methods can be used. However, preferably, the CO2 shielded arc welding process is used for welding and fixing.

[0048] In addition, as Figure 6 、 Figure 7As shown, flanges 303 are formed at the edge parts of the lower plate bodies 301 of the front mounting plate 31 and the rear mounting plate 32 of this embodiment, and the two flanges 303 belonging to the front mounting plate 31 and the rear mounting plate 32 are overlapped and connected. By providing flanges 303 at the edges of the lower plate bodies 301 of the front mounting plate 31 and the rear mounting plate 32, and using the lap joint between the two flanges 303 belonging to the front mounting plate 31 and the rear mounting plate 32, the middle and lower parts of the front mounting plate 31 and the rear mounting plate 32 can be connected together to form support for each other, which can further improve the overall structural stability of the mounting bracket 3.

[0049] Based on the above settings, preferably, the flange 303 of this embodiment is configured as an arched structure protruding downward toward the bottom of the bumper beam body 1, and both ends of the flange 303 are overlapped on the bottom of the bumper beam body 1. By reasonably setting the shape of the lower plate body 301, the flange 303 located at its edge can be designed as a downwardly convex arched structure; in this embodiment, the lower plate body 301 is generally semicircular, protruding downward from the middle part of the lower side of the upper plate body 300. In this way, the flange 303 is formed into an arched shape accordingly. With the help of the connection parts between the two ends of the lower plate body 301 and the connecting section of the upper plate body 300, both ends of the flange 303 can be designed to be in a horizontal state to overlap on the bottom of the bumper beam body 1. The above design form of the flange 303 can greatly improve the self-structural stability of the lower plate body 301, and further improve the structural stability of the lower connecting part of the mounting bracket 3.

[0050] Regarding the specific setting method of the trailer hitch mounting sleeve 4 on the mounting bracket 3, of course, there are also many different structural solutions to choose from; for example, different methods such as screw connection and welding can be adopted. In this embodiment, insertion holes 30 are provided on the lower plate bodies 301 of the front mounting plate 31 and the rear mounting plate 32, and the trailer hitch mounting sleeve 4 is inserted into the insertion holes 30 of the front mounting plate 31 and the rear mounting plate 32. By providing the insertion holes 30 on the lower plate bodies 301 of the front mounting plate 31 and the rear mounting plate 32, the convenient insertion and fixation of the trailer hitch mounting sleeve 4 on the lower connection part can be realized, providing good installation conditions for the configuration of the trailer hitch mounting sleeve 4 on the mounting bracket 3. As mentioned above, the trailer hitch mounting sleeve 4 and the mounting bracket 3 can be fixedly connected by welding. After the trailer hitch mounting sleeve 4 is inserted into the insertion holes 30 on the front mounting plate 31 and the rear mounting plate 32, the trailer hitch mounting sleeve 4 can be welded and fixed at the insertion holes 30 of the two plate bodies by CO2 shielded welding; in addition, to improve the stress state between the trailer hitch mounting sleeve 4 and the lower connection part, a retaining platform (not shown in the figure) and other structures can be provided at the rear end of the trailer hitch mounting sleeve 4, and the retaining platform is left inside the rear mounting plate 32. In this way, when the trailer hitch mounting sleeve 4 is subjected to a pulling force, the trailer hitch mounting sleeve 4 will transfer most of the force to the rear mounting plate 32 through the retaining platform, thereby reducing the stress burden on the weld between the trailer hitch mounting sleeve 4 and the lower plate body 301.

[0051] In addition, as Figure 6 shown, reinforcing bosses 304 located at the insertion holes 30 are formed on the lower plate bodies 301 of the front mounting plate 31 and the rear mounting plate 32, and the insertion holes 30 are opened on the reinforcing bosses 304. By providing the reinforcing bosses 304 at the positions where the insertion holes 30 are opened on the lower plate body 301, the structural strength and stability of this part can be improved, thereby reducing the risk of cracking and deformation of the lower plate body 301 during the pulling process by the trailer hitch mounting sleeve 4.

[0052] Based on the above overall setting situation, taking the anti-collision beam assembly applied to the front anti-collision beam as an example, the anti-collision beam assembly of this embodiment effectively reduces the setting height of the trailer hitch; when the front anti-collision beam of the vehicle adopts the anti-collision beam assembly of this embodiment, the stress state of the vehicle being towed as a trapped vehicle is as Figure 8 shown, where the stress situation of the anti-collision beam assembly of this embodiment is as indicated by the solid arrows in Figure 8 , and the stress situation of the conventional anti-collision beam assembly is as indicated by the dashed arrows in Figure 8 ; compared with the situation where the conventional trailer hitch is directly provided on the anti-collision beam body 1, the anti-collision beam assembly of this embodiment has a better stress state.

[0053] In Figure 8In the figure, T is the pulling point of the rescue vehicle, G is the center of gravity of the trapped vehicle, F0 is the dragging force provided by the force point of the conventional anti-collision beam assembly, F1 is the dragging force provided by the force point of the anti-collision beam assembly of the utility model, and F is the horizontal resistance of the trapped vehicle.

[0054] In the anti-collision beam assembly of the utility model: F = F1*cosθ1, that is, F1 = F / cosθ1;

[0055] In the conventional structure: F = F0*cosθ2*cosθ2, that is, F0 = F / (cosθ2*cosθ2);

[0056] Because θ1<θ2<90°, cosθ1>cosθ2>cosθ2*cosθ2.

[0057] Moreover, in the anti-collision beam assembly of the present invention, the drag force F1 also generates a portion of upward pulling force, thereby offsetting a portion of the gravity of the vehicle body, thereby reducing the horizontal resistance F, which is more conducive to reducing the difficulty of dragging.

[0058] For better quantitative comparison, even if we temporarily assume that the horizontal resistance F of the vehicle is the same in the two cases, it can be seen from the above derivation process that: F1<F0, that is, compared with the conventional anti-collision beam assembly, the anti-collision beam assembly of the patent is easier to be rescued when the vehicle weight is the same.

[0059] Moreover, most of the force of the conventional trailer hook mounting sleeve 4 is concentrated on the weld between it and the anti-collision beam body 1, which makes the trailer hook mounting sleeve 4 easy to break and fall off. The trailer hook mounting sleeve 4 of the utility model is arranged downward and fixed on the front mounting plate 31 and the rear mounting plate 32. During the force-bearing process, part of the force can be dispersed to the two mounting plates, so as to better disperse the force and transmit it to the anti-collision beam body 1, reducing the risk of cracking and falling off of the trailer hook mounting sleeve 4, and on the other hand, also improving the safety of the rescue process.

[0060] To sum up, the anti-collision beam assembly of the present embodiment, by arranging a mounting frame 3 on the anti-collision beam body 1, arranging a lower connecting portion located below the anti-collision beam body 1 on the mounting frame 3, and arranging the trailer hook mounting sleeve 4 on the lower connecting portion, is conducive to lowering the height of the installation position point of the trailer hook, so that the trailer hook is closer to the center of gravity of the towing vehicle in the height direction of the vehicle; this has a good effect on reducing the dragging force when the vehicle is out of trouble, improving the stress state of the anti-collision beam assembly when towing, etc., thereby making the vehicle rescue process more efficient and safe.

[0061] Embodiment 2

[0062] This embodiment relates to a vehicle, on which the anti-collision beam assembly provided in the first embodiment is provided.

[0063] When the anti-collision beam assembly of the present utility model is adopted on a vehicle, by adding the mounting bracket 3, the installation position of the towing hook mounting sleeve 4 is lowered, and thus the stress point position of the towing hook is lowered, which is beneficial to reducing the towing force and reducing the risks of the towing hook mounting sleeve 4 falling off and the anti-collision beam body 1 deforming, and improving the towing efficiency and safety. Moreover, the anti-collision beam assembly of the present utility model can not only be applied to SUV models with a load-bearing body, but also be extended to sedan models with a load-bearing body, with strong expandability and good versatility.

[0064] The above are only the preferred embodiments of the present utility model. The detailed explanation of the configuration, the examples of the specific structural forms, or the description of the assembly connection methods, etc., are all for the need of full disclosure so that those skilled in the art can better implement the present utility model, rather than being used to limit the protection scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
