[0035] As Figure 1 shown, the present utility model provides a trailer connection device, which includes a fixing frame 1, a connecting line 2, a winch mechanism 5, and a positioning assembly; the fixing frame 1 includes a positioning portion 101 and a connecting portion 102, the positioning portion 101 is formed with a positioning hole 1013, the positioning assembly includes a first positioning member 3, and the first positioning member 3 passes through the positioning hole 1013 and is connected to the winch mechanism 5; the connecting portion 102 is formed with a limiting space 1021, one end of the connecting line 2 is located in the limiting space 1021, and one end of the connecting line 2 is connected to the connecting portion 102; the winch mechanism 5 is connected to the main vehicle, and the other end of the connecting line 2 is connected to the main vehicle.

[0036] Compared with the prior art, the trailer connection device provided by the present utility model has the following advantages:

[0037] The trailer connection device provided by the present utility model can achieve a stable connection between the fixing frame 1 and the winch mechanism 5 through the positioning portion 101 of the fixing frame 1, and a positioning hole 1013 is formed in the positioning portion 101. Through the limiting space 1021 formed by the connecting portion 102, one end of the connecting line 2 can be limited and an installation position can be provided, so as to limit and connect the connecting line 2, and avoid problems such as damage to the line caused by the free scattering of the connecting line 2 or affecting the layout of other wire harnesses.

[0038] Moreover, since the connecting portion 102 in this application limits one end of the connecting line 2, and this end is the connecting end of the connecting line 2 and the docking line in the trailer, therefore, limiting and connecting this end can also facilitate the subsequent connection process with the docking line to a certain extent.

[0039] Optionally, as Figure 1 shown in combination with Figure 2 Figure, the connecting portion 102 in this application has a superior arc structure, and an opening is formed in the connecting portion 102. The connecting line 2 can enter the limiting space 1021 formed by the connecting portion 102 from the opening.

[0040] It can be understood that the connecting line 2 in this application includes a connecting line segment and a joint segment. The diameter of the joint segment is greater than the inner diameter of the limiting space 1021, while the diameter of the connecting line segment is less than the inner diameter of the limiting space 1021. By making the connecting portion 102 have a superior arc structure in this application, the width of the opening can be made less than the diameter of the joint segment and greater than the diameter of the connecting line segment. Thus, during installation, the connecting line segment can first pass through the opening and enter the limiting space 1021, and then the joint segment is connected to the connecting portion 102 to achieve the installation between the connecting line 2 and the fixing frame 1, ensuring the stability of their connection.

[0041] Optionally, as Figure 1 shown in combination with Figure 2 Figure, a plurality of connection holes 1022 are formed on the connecting portion 102 in this application, and the plurality of connection holes 1022 are evenly distributed on the connecting portion 102; the positioning assembly further includes a second positioning member 4, and the second positioning member 4 passes through the connecting line 2 and is connected to the connection holes 1022 to connect one end of the connecting line 2 to the connecting portion 102.

[0042] By forming a plurality of connection holes 1022 on the connecting portion 102 and using the second positioning member 4 to pass through the connecting line segment and connect to the connection holes 1022, a stable connection between the connecting line 2 and the fixing frame 1 can be achieved. By making the connection holes 1022 evenly distributed on the connecting portion 102, the connecting line 2 and the connecting portion 102 can be stressed evenly after connection, further ensuring the connection stability.

[0043] It should be noted here that the connection between the connecting line 2 and the connecting part 102 in this application refers to the connection between the above-mentioned joint section and the connecting part 102. Correspondingly, mounting holes matching the connecting holes 1022 are formed at the edges of the joint section, so that the second positioning member 4 passes through the mounting holes and is connected to the connecting holes 1022 to achieve the positioning of the joint section.

[0044] Preferably, projection welding nuts are provided at the positions of the connecting part 102 corresponding to the connecting holes 1022 in this application, and the projection welding nuts are arranged in one-to-one correspondence with the connecting holes 1022.

[0045] Through the formed projection welding nuts, the rapid connection between the second positioning member 4 and the connecting part 102 can be achieved.

[0046] Correspondingly, the second positioning member 4 in this application is a bolt, so that it can be adapted to the projection welding nut. Moreover, the second positioning member 4 in this application is a cross-head bolt, which can facilitate the screwing operation.

[0047] Furthermore, as Figure 3 shown, alignment holes are formed at the positions of the winch mechanism 5 corresponding to the positioning holes 1013 in this application, and the first positioning member 3 passes through the positioning holes 1013 and is connected to the alignment holes.

[0048] It can be understood that the first positioning member 3 in this application also uses a bolt, and the rapid disassembly and assembly between the fixing frame 1 and the winch mechanism 5 can be achieved through the bolt. Moreover, the first positioning member 3 in this application is an M6 bolt.

[0049] Preferably, as Figure 1 combined with Figure 2 shown, the positioning part 101 in this application includes a transition section 1011 and a positioning section 1012. The positioning holes 1013 are formed on the positioning section 1012. The positioning section 1012 is arranged at a right angle to the transition section 1011, and the transition section 1011 is connected to the connecting part 102.

[0050] By setting the positioning section 1012 and the transition section 1011 at a right angle, and the transition section 1011 is located between the positioning section 1012 and the connecting part 102, so that when the positioning section 1012 is connected to the winch mechanism 5, the orientation of the limiting space 1021 of the connecting part 102 can be made outward, and thus it is convenient to connect with the docking line of the trailer subsequently.

[0051] Preferably, the diameter of the positioning hole 1013 in this application is 7 mm, and the diameter of the connecting hole 1022 is 6 mm.

[0052] Since the fixing bracket 1 needs to be connected to the winch mechanism 5 through the positioning hole 1013, in order to ensure the connection stability, in this application, the diameter of the positioning hole 1013 is made 7 mm, so as to be able to match the diameter of the M6 bolt and provide a greater fastening force for the connection between the fixing bracket 1 and the winch mechanism 5.

[0053] And since the connecting wire 2 is of light weight and does not require a large positioning force, a screw hole with a smaller diameter can be used, and positioning and connection can be completed by using a cross-head bolt.

[0054] In addition, the present utility model also provides a vehicle system, which includes a main vehicle, a trailer and the above-mentioned trailer connection device; the trailer includes a main body and a docking wire, one end of the docking wire is connected to the trailer, and the other end is connected to one end of the connecting wire 2 connected to the connecting part 102, and the other end of the connecting wire 2 is connected to the main vehicle.

[0055] For the vehicle system adopting the trailer connection device provided by this application, when it is necessary to connect the trailer to the main vehicle, the docking wire of the trailer can be quickly connected to the connecting wire 2 of the main vehicle, and the connecting wire 2 of the main vehicle is always limited, thus ensuring the stability and safety of the overall transmission line.

[0056] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
