The first plug tube 3111 and the second plug tube 3211 are plugged together in a manner of one inserting into the other; wherein the plug-in structure further includes a locking member 4, which passes through the first plug tube 3111 and the second plug tube 3211 in sequence to fix the first plug tube 3111 and the second plug tube 3211 together. The plug-in matching of the first plug tube 3111 and the second plug tube 3211 is achieved by plugging the first plug tube 3111 and the second plug tube 3211 together in a manner of one inserting into the other, and the plug-in is convenient and fast, thereby facilitating the connection between the second traction part 32 and the first traction part 31. The arrangement of the locking member 4 facilitates fixing the first plug-in tube 3111 and the second plug-in tube 3211 together, thereby effectively preventing the second plug-in tube 3211 from falling off from the first plug-in tube 3111, thereby ensuring connection reliability. A sleeve 314 may be arranged outside the first plug-in tube 3111 to further improve the connection reliability between the second traction part 32 and the first traction part 31. It should be noted that the locking member 4 may be constructed in any suitable manner. Optionally, refer to Figure 2 As shown, the locking member 4 can be constructed as a fixing pin, which can completely penetrate the first plug-in tube 3111 and the second plug-in tube 3211, or can only penetrate a portion of the first plug-in tube 3111 and the second plug-in tube 3211, and the present disclosure does not impose any limitation on this.

[0048] refer to Figure 1 and Figure 4 As shown, the upper and lower ends of the first plug-in tube 3111 are respectively connected to the first beam body 11 and the second beam body 12 through the towing connecting plates 312, and each towing connecting plate 312 is welded to the outer wall of the first plug-in tube 3111 and is respectively connected to the first beam body 11 and the second beam body 12 through fasteners. In addition, in order to improve the connection reliability, the two ends of the first plug-in tube 3111 can also be provided with towing reinforcement plates 313, and the towing reinforcement plates 313 are respectively connected to the first plug-in tube 3111 and the towing connecting plates 312. In addition, the towing reinforcement plates 313 can also be bolted to the first beam body 11 and the second beam body 12 to further improve the connection reliability.

[0049] In the specific embodiments provided in the present disclosure, reference is made to Figure 1 and Figure 4 As shown, the cross beam 1 is provided with a trailer hook 6. When not towing a trailer, the trailer hook 6 has the function of a rear trailer hook, which avoids the situation where it is hung on the rear leaf spring eye when towing other vehicles, causing damage to the corresponding parts, and / or, the cross beam 1 is provided with a fourth mounting bracket 7 for installing power supply accessories. The fourth mounting bracket 7 is provided to provide a mounting point for electrical accessories (such as a trailer connector socket, etc.), with a reasonable layout, high integration and a more compact structure. Among them, the fourth mounting bracket 7 can be constructed in a variety of ways, and the present disclosure does not impose any restrictions on this. Those skilled in the art can selectively design it according to actual needs.

[0050] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0051] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0052] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
