[0002] In recent years, with the development of domestic brand cars, more and more automobile companies have begun to increase their export business, especially in the European and American markets, where the demand for station wagons is growing. Station wagons are connected to tractors through a traction mechanism and driven by the tractor. They are suitable for parks, resorts, tourist areas or short trips. Existing traction mechanisms usually use a trailer hook to connect the tractor and the station wagon. However, the existing trailer hook usually protrudes from the body of the vehicle, cannot be folded, occupies a large space, and is inconvenient to use. Utility Model Content

[0003] Based on this, it is necessary to provide a tractor trailer structure that can solve the above problems.

[0004] In order to solve the above technical problems, this application provides the following technical solutions:

[0005] A tractor trailer structure, the tractor trailer structure comprising:

[0006] Tractor;

[0008] A traction assembly connected between the tractor and the trailer, wherein the tractor can drive the trailer to travel through the traction assembly; the traction assembly includes a plurality of traction frames, one end of each traction frame is rotatably connected to one of the tractor or the trailer, and the other end of each traction frame is detachably connected to the other one;

[0009] When the towing assembly is detached from one of the tractor or the trailer, the plurality of towing frames can be restrained to the other one.

[0010] It can be understood that the tractor is connected to the trailer through the towing frame, and when the towing assembly is detached from the tractor or trailer, the towing frame can be limited so that the towing frame can be folded on the tractor or trailer. The towing assembly occupies a small space, has a high degree of integration, improves the appearance, and is more convenient to use.

[0011] In one embodiment, the traction frame is rotatably connected to the tractor.

[0012] In one embodiment, the traction frame includes a rotating shaft and a connecting rod connected to each other, the rotating shaft is rotatably connected to the tractor, and the connecting rod can swing under the drive of the rotating shaft and be connected to the trailer.

[0013] In one embodiment, the number of the traction frames is two, and the two traction frames are arranged on the tractor at intervals along the width direction of the tractor.

[0014] It is understandable that providing two towing frames on the tractor is beneficial to balancing the forces when the towing frames are connected to the trailer, thereby improving the connection stability.

[0015] In one embodiment, the two traction frames are respectively set as a first traction frame and a second traction frame, the first traction frame is formed with a first connection portion on the connecting rod, the second traction frame is formed with a second connection portion on the connecting rod, and the first connection portion and the second connection portion are used to connect with the trailer;

[0016] The two connecting rods are arranged in a straight line, and a groove is provided on the second connecting portion. When the traction frame is limited to the tractor, the first connecting portion can at least partially extend into the second connecting portion and be located in the groove.

[0017] It can be understood that the first connecting portion can at least partially extend into the second connecting portion and be located in the groove, so that the two connecting rods partially overlap, thereby improving space utilization and ensuring that the two connecting rods have sufficient length.

[0018] In one embodiment, the traction assembly further includes a fixing member, and when the traction frame is limited to the traction vehicle, the first connection portion is connected to the second connection portion through the fixing member, and along the height direction of the traction vehicle, the fixing member is arranged through the first connection portion and the second connection portion.

[0019] It can be understood that the fixing piece is passed through the first connecting portion and the second connecting portion so that the two connecting rods are connected to each other, thereby achieving the limiting of the traction frame on the tractor.

[0020] In one embodiment, the traction assembly further includes a locking member, and the locking member can be connected to the fixing member to limit the fixing member to the traction frame.

[0021] It is understandable that the locking member is connected to the fixing member so that when the fixing member is inserted into the first connecting portion and the second connecting portion, the fixing member is prevented from falling out.

[0022] In one of the embodiments, the traction frame is configured as an electrically controlled traction frame.

[0024] In one of the embodiments, a connecting hole is provided on the trailer, and a telescopic member is provided in the connecting hole, and the telescopic member can perform telescopic movement in the height direction of the trailer to lock the connecting rod extended into the connecting hole in the connecting hole or unlock the connecting rod.

[0025] It is understandable that the telescopic member is provided to lock the connecting rod in the connecting hole to prevent the traction frame from being separated from the trailer.

[0026] In one of the embodiments, a through hole is provided on the connecting rod, and when the connecting rod is connected to the trailer, the outer peripheral wall of the telescopic member is in contact with the hole wall of the through hole and is circumferentially limited by the hole wall of the through hole.

[0027] It can be understood that the outer peripheral wall of the telescopic part is attached to the hole wall of the through hole and limited circumferentially so that there is no gap between the telescopic part and the hole wall of the through hole, thereby avoiding abnormal noise during connection and making the connection more stable.

[0028] Due to the application of the above solution, the present application has the following advantages compared with the prior art:

[0029] The tractor-trailer structure for which protection is sought in the present application connects the tractor and the trailer via a towing frame, and when the towing assembly is detached from the tractor or the trailer, the towing frame can be limited so that the towing frame can be folded onto the tractor or the trailer. The towing assembly occupies a small space, has a high degree of integration, and improves the aesthetic appearance. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] See also Figures 1 to 3A tractor trailer structure 100 provided in one embodiment of the present application includes a tractor 10, a trailer 20 and a traction assembly 30. The traction assembly 30 is connected between the tractor 10 and the trailer 20. The tractor 10 can drive the trailer 20 to travel through the traction assembly 30. The traction assembly 30 includes a plurality of traction frames 31. One end of the traction frame 31 is rotatably connected to one of the tractor 10 or the trailer 20, and the other end of the traction frame 31 is detachably connected to the other. When the traction assembly 30 is separated from one of the tractor 10 or the trailer 20, the plurality of traction frames 31 can be limited to the other, so that the traction frames 31 can be folded on the tractor 10 or the trailer 20. The traction assembly 30 occupies a small space, has a high degree of integration, and improves the aesthetics of the shape.

[0050] In this embodiment, the tractor 10 can be configured as a sedan or SUV, etc., and the trailer 20 can be configured as a station wagon, and people can rest, sleep, etc. in the trailer 20.

[0051] like Figure 1 and Figure 2 As shown, in this embodiment, one end of the traction frame 31 is rotatably connected to the tractor 10 , and the other end is detachably connected to the trailer 20 .

[0052] Not limited thereto, in other embodiments, the traction frame 31 may also be rotatably connected to the trailer 20 and detachably connected to the tractor 10 .

[0053] like Figure 3 and Figure 4 As shown, in one embodiment, a plurality of mounting grooves 11 are provided on the tractor 10 , and the plurality of mounting grooves 11 are arranged corresponding to a plurality of traction frames 31 . The traction frames 31 are partially arranged in the corresponding mounting grooves 11 and are rotatably connected to the groove walls of the mounting grooves 11 .

[0054] like Figure 5 and Figure 6 As shown, in one embodiment, the traction frame 31 includes a rotating shaft 311 and a connecting rod 312 connected to each other, the rotating shaft 311 is rotatably connected to the tractor 10, and the connecting rod 312 can swing under the drive of the rotating shaft 311 and is connected to the trailer 20. The rotating shaft 311 is located in the installation groove 11, and the connecting rod 312 is arranged perpendicular to the rotating shaft 311. When the rotating shaft 311 rotates around its center line, the connecting rod 312 can be driven by the rotating shaft 311 to form an angle with the body of the tractor 10.

[0055] like Figure 4As shown, in this embodiment, the groove wall of each mounting groove 11 is provided with two mounting holes 12, and the two mounting holes 12 are coaxially arranged up and down. Both ends of the rotating shaft 311 are installed in the corresponding mounting holes 12. Bearings are arranged in the mounting holes 12, so that the rotating shaft 311 can rotate in cooperation with the bearings, and the rotating shaft 311 has a certain damping during the rotation process to prevent the traction frame 31 from generating abnormal noise during the movement process.

[0056] In one embodiment, there are two traction frames 31, and the two traction frames 31 are arranged on the tractor 10 at intervals along the width direction of the tractor 10, which is conducive to the force balance when the traction frame 31 is connected to the trailer 20, and improves the connection stability. Two mounting grooves 11 are correspondingly provided on the tractor 10, and the two mounting grooves 11 are symmetrically arranged at the rear of the tractor 10, so that the two traction frames 31 correspondingly installed on the two mounting grooves 11 are balanced in force.

[0057] Not limited to this, in other embodiments, the number of traction frames 31 can also be set to three or four, etc., which can be selected according to actual needs.

[0058] like Figure 5 and Figure 6 As shown, in one embodiment, the two traction frames 31 are respectively set as a first traction frame 313 and a second traction frame 314, the first traction frame 313 is formed with a first connection portion 3121 on the connecting rod 312, and the second traction frame 314 is formed with a second connection portion 3122 on the connecting rod 312, and the first connection portion 3121 and the second connection portion 3122 are used to connect with the trailer 20.

[0059] The two connecting rods 312 are arranged in a straight line, and a groove 3123 is provided on the second connecting portion 3122. When the traction frame 31 is limited to the tractor 10, the first connecting portion 3121 can at least partially extend into the second connecting portion 3122 and be located in the groove 3123, so that the two connecting rods 312 partially overlap, thereby improving space utilization and ensuring that the two connecting rods 312 have sufficient length.

[0060] like Figure 5 and Figure 7 As shown, in one embodiment, the traction assembly 30 further includes a fixing member 32. When the traction frame 31 is limited to the tractor 10, the first connection portion 3121 is connected to the second connection portion 3122 through the fixing member 32. Along the height direction of the tractor 10, the fixing member 32 is arranged to penetrate the first connection portion 3121 and the second connection portion 3122, so that the first connection portion 3121 and the second connection portion 3122 are connected to each other, thereby realizing the limitation of the traction frame 31 on the tractor 10.

[0061] like Figure 5 and Figure 7As shown, in one embodiment, the traction assembly 30 further includes a locking member 33, which can be connected to the fixing member 32 to limit the fixing member 32 to the traction frame 31, so that when the fixing member 32 is inserted into the first connection portion 3121 and the second connection portion 3122, the fixing member 32 is prevented from falling out. Specifically, the locking member 33 is configured as a nut and is threadedly connected to the fixing member 32.

[0062] In one embodiment, the traction frame 31 is configured as an electrically controlled traction frame, so that the traction frame 31 can be automatically folded or unfolded, thereby improving the automation and intelligence level of the traction component 30 and enhancing user comfort.

[0063] like Figures 8 to 12 As shown, in one embodiment, a connecting hole 21 is provided on the trailer 20, and a telescopic member 22 is arranged in the connecting hole 21, and the telescopic member 22 can perform telescopic movement in the height direction of the trailer 20, so as to lock the connecting rod 312 inserted into the connecting hole 21 in the connecting hole 21 or release the locking of the connecting rod 312, so as to prevent the traction frame 31 from being separated from the trailer 20, and thereby realize the detachable connection between the traction frame 31 and the trailer 20. A locking pin hole 23 is provided on the hole wall of the connecting hole 21, and the locking pin hole 23 can cooperate with the telescopic member 22. When the telescopic member 22 moves along its own axial direction, the telescopic member 22 can extend into the locking pin hole 23, and the locking pin hole 23 can lock or unlock the telescopic member 22.

[0064] like Fig.11 and Fig.12 As shown, the cross section of the telescopic member 22 is hexagonal, and the cross section of the locking pin hole 23 is hexagonal, so when the telescopic member 22 extends into the locking pin hole 23 and is limitedly engaged with the hole wall of the locking pin hole 23, the stability is better.

[0065] In one embodiment, a through hole 3124 is opened on the connecting rod 312. When the connecting rod 312 is connected to the trailer 20, the outer peripheral wall of the telescopic member 22 is in contact with the hole wall of the through hole 3124 and is circumferentially limited by the hole wall of the through hole 3124, so that there is no gap between the telescopic member 22 and the hole wall of the through hole 3124, thereby avoiding abnormal noise during connection and making the connection more stable.

[0066] In this embodiment, the cross-section of the telescopic member 22 is set to be a hexagon, and the shape of the corresponding through hole 3124 is also a hexagon, which improves the firmness of the connection between the telescopic member 22 and the through hole 3124.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
