DETAILED DESCRIPTION

[0029] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0030] In the present disclosure, the positional words such as "inner, outer" used without the opposite description refer to the inner and outer relative to the outline of the component or structure itself; "first, second" and the like are to distinguish one element from another element, and do not have sequentiality and importance, and in addition, the same reference numerals in different reference drawings represent the same element.

[0031] In a first aspect of the present disclosure, a trailer mechanism is provided, referring to Figures 1 to 10As shown, the trailer mechanism includes a rod body 1 and a hitch assembly 3, the rod body 1 includes opposite first and second ends, the first end is provided with a first locking piece 110, the first locking piece 110 is used for detachably connecting to a matching device 2 of a vehicle, the hitch assembly 3 includes two fork arms 310 and a hitch 320, the two fork arms 310 are connected to the second end at intervals, the fork arms 310 are provided with first mounting holes 311, and the hitch 320 is arranged through the two first mounting holes 311.

[0032] Through the above technical solution, that is, the trailer mechanism provided by the present disclosure, when the trailer operation is performed through the trailer mechanism, the first locking piece 110 can be connected to the matching device 2 of the vehicle (for example, a rear vehicle that needs to be towed), and the hitch or other external hanging parts can be hung on the hitch 320, that is, the trailer operation of the front vehicle towing the rear vehicle can be realized, and the rod body 1 can also extend the hitch assembly 3 to the outside of the vehicle, thereby preventing the rod body 1 from colliding with the front wall component (for example, the front wall plate) of the rear vehicle when the front vehicle tows the rear vehicle to turn, so as to reduce the damage of the front wall component of the rear vehicle.

[0033] It should be noted that the connection relationship between the first locking piece 110 and the matching device 2 mentioned in the above embodiment can be constructed in any suitable manner, for example, threaded connection, buckle connection, positioning pin and positioning hole connection, and other modes capable of realizing detachable connection, and the present disclosure will be illustrated and described in detail below, and will not be described here.

[0034] In some embodiments, referring to Figures 1 to 6 As shown, the hitch assembly 3 further includes a limiting piece 330, the limiting piece 330 is connected to the hitch 320, so as to lock the hitch 320 after the hitch 320 passes through the two first mounting holes 311. In this way, when the hitch 320 passes through the two first mounting holes 311 of the fork arms 310, the relative position of the hitch 320 and the two fork arms 310 can be fixed and limited by the limiting piece 330, that is Figure 1 or Figure 3 As shown, in this state, when the hitch 320 is hung by the hook or other external hanging parts or in a natural state, the hitch 320 will not be separated from the fork arms 310, thereby improving the stability of the connection between the hitch 320 and the fork arms 310.

[0035] In some embodiments, referring to Figures 1 to 6As shown, one end of the hanger shaft 320 is provided with a stopper 322, and the side wall of the other end is provided with a second mounting hole 323. The limiting member 330 is configured as a positioning pin inserted into the second mounting hole 323. In this way, when the hanger shaft 320 passes through the two first mounting holes 311 of the two fork arms 310 in sequence, the one end of the hanger shaft 320 can be stopped by the stopper 322, and the other end of the hanger shaft 320 can be locked and limited by inserting the positioning pin into the second mounting hole 323, that is, referring to Figure 6 As shown, in Figure 6 In the embodiment shown, the stopper 322 can be a disc with an outer diameter greater than the first mounting hole 311. The face body on the side close to one of the fork arms 310 can limit the one end of the hanger shaft 320 by fitting the outer side wall of the fork arm 310, and the other end can be limited and fixed by inserting the positioning pin into the second mounting hole 323. In Figure 6 When the disc is fitted to the fork arm 310, the second mounting hole 323 on the hanger shaft 320 can be located on the side away from the two fork arms 310. At this time, the positioning pin can be inserted into the second mounting hole 323. The part of the positioning pin exposed on the outer side wall outside the second mounting hole 323 can limit the hanger shaft 320, thereby preventing the hanger shaft 320 from being separated from the two fork arms 310. In order to further improve the cooperation effect of the positioning pin and the second mounting hole 323, the outer diameter of the positioning pin can be equal to the hole diameter of the second mounting hole 323, thereby preventing the positioning pin from shaking relative to the second mounting hole 323 after being inserted into the second mounting hole 323, and improving the stability of the connection between the positioning pin and the second mounting hole 323.

[0036] In some embodiments, referring to Figures 1 to 6 As shown, the two fork arms 310 are arranged in parallel and spaced apart. In this arrangement, when the hook of the current vehicle hooks the hanger shaft 320, the two parallel fork arms 310 can uniformly bear the force generated by the hanger shaft 320 on the fork arms 310, that is, the force on the two fork arms 310 is the same, and the two fork arms 310 can jointly bear the force of the hanger shaft 320, thereby improving the force stability of the hanger assembly 3 as a whole.

[0037] In a second aspect of the present disclosure, a trailer device is provided, referring to Figures 1 to 10As shown, the trailer device includes the trailer mechanism and the matching device 2 in the above-mentioned embodiments, and the trailer mechanism has all the beneficial effects in the above-mentioned embodiments, and the matching device 2 includes the first matching part 210 and the fixing part 220 connected to the first matching part 210, and the first matching part 210 is detachably connected to the first locking part 110, and the fixing part 220 is used to connect the vehicle. In this way, the trailer device can be connected to the vehicle body (such as the frame) of the vehicle through the fixing part 220 of the matching device 2, and the first locking part 110 of the trailer mechanism can be locked and connected with the first matching part 210 of the matching device 2, and then the trailer operation can be realized by hanging the hanger shaft 320 of the trailer mechanism through the trailer hook of the front vehicle, and when the matching device 2 is connected to the vehicle body (such as the frame) of the vehicle, it is generally inside the vehicle body of the rear vehicle. In this state, when the trailer mechanism is connected to the matching device 2, the trailer mechanism can also be extended to the outside of the vehicle body of the rear vehicle through the extended rod body 1, and at this time, the connection point of the hanger shaft of the trailer mechanism and the hook of the front vehicle is also outside the vehicle body. In this arrangement, when the front vehicle drags the rear vehicle to turn, the trailer mechanism can also prevent the front wall part (such as the front wall plate) of the rear vehicle from being hit, thereby reducing the risk of damage to the front wall part of the vehicle. After the trailer operation is completed, the trailer hook can be disconnected from the hanger shaft 320, and the first matching part 210 and the first locking part 110 can be unlocked to complete the unlocking of the trailer mechanism and the matching device 2, and then the fixing part 220 can be disconnected from the vehicle body (such as the frame) of the vehicle to realize the separation of the matching device 2 and the vehicle. At this time, the trailer mechanism and the matching device can be stored after being disassembled, thereby saving the occupied space of the entire trailer device when not in use.

[0038] In some embodiments, referring to Figures 1 to 10 As shown, the first locking part 110 includes a threaded rod 111, and the first matching part 210 includes a threaded hole 211 threadedly connected with the threaded rod 111. In this way, the trailer mechanism and the matching device 2 can be connected in a threaded manner, that is, through the threaded connection of the threaded rod 111 and the threaded hole 211 to lock or unlock each other, and the threaded connection has high stability and is also convenient for quick locking and unlocking of the first locking part 110 and the first matching part 210.

In this way, the reinforcing ribs 2131 can further improve the deformation resistance of the sleeve 213, and with reference to Figure 7 As shown, the reinforcing ribs 2131 can be spaced apart by four around the outer wall of the sleeve 213, and the four reinforcing ribs 2131 can be spaced apart by 90° two by two, thereby better resisting deformation of the outer wall of the sleeve 213.

[0041] It should be noted that Figure 7 The number of reinforcing ribs 2131 shown in the above is four, which is exemplary, and in embodiments not shown in the drawings, the reinforcing ribs 2131 can also be other suitable numbers, such as three, five or more, and the spacing angles of the plurality of reinforcing ribs 2131 on the outer wall of the sleeve 213 can be the same or different, and the present disclosure does not make specific limitations thereon.

[0042] In some embodiments, with reference to Figures 1 to 10 As shown, the fixing member 220 comprises a mounting plate 221 comprising opposite first and second faces and a plurality of third mounting holes 2211 penetrating through the first and second faces, and the first face is connected to the shaft portion 212, and the second face is used to connect the vehicle. In this way, when the fitting device 2 needs to be connected to the body of the vehicle, the second face of the mounting plate 221 can be attached to the body of the vehicle, and then connected to the body of the vehicle through the third mounting holes 2211 and components such as bolts or positioning pins, thereby achieving the fixation of the fixing member 220 and the body of the vehicle.

[0043] Alternatively, in an embodiment not shown in the drawings, the second face of the mounting plate 221 can also be connected to the vehicle by welding, and the cooperation device 2 can be fixedly connected to the vehicle in this way. In this way, after the trailer is operated, the cooperation device 2 can be left on the frame of the rear vehicle, and at this time, the threaded rod 111 of the trailer mechanism can be screwed out of the threaded hole 211, and the trailer mechanism can be stored.

[0044] In a third aspect of the present disclosure, a vehicle is provided, which comprises a vehicle body and the trailer device mentioned in the above embodiments. The cooperation device 2 is arranged at the front end of the vehicle body, and the trailer mechanism is detachably connected to the first cooperation part 210 at the end of the cooperation device 2 away from the vehicle body. The trailer device has all the beneficial effects of the above embodiments, and can be widely used in the towing of various vehicles, such as cars, buses, trucks, etc. The towing of the above different types of vehicles can be achieved by the trailer device.

[0045] The preferred embodiments of the present disclosure are described in detail above with reference to the drawings, but the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0046] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0047] Furthermore, any combination of the various different embodiments of the present disclosure can also be made, as long as it does not deviate from the idea of the present disclosure, and it should be considered as disclosed by the present disclosure.
