[0028] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0029] The following describes the embodiments of the present application in detail, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limiting the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0030] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0031] The present application embodiment provides a trailer, combined with Figures 1 to 3 As shown, the trailer of the embodiment of the present application includes a trailer body 100 and a body driving structure, wherein the body driving structure includes a driving disc 300 and a driving arm group, wherein the driving arm group is located between the driving disc 300 and the trailer body 100, and the driving disc 300 can move between a locking position and an ejecting position;

[0032] When the driving disc 300 is in the locking position, the trailer body 100 is locked with six degrees of freedom through the driving arm assembly, so that the trailer body 100 is locked on the trailer body 400;

[0033] When the driving disc 300 is in the ejection position, the trailer body 100 is ejected by the driving arm assembly, so that the trailer body 100 slides out of the trailer body 400 .

[0034] In an embodiment of the present application, a body driving structure is provided for the trailer body. The body driving structure includes a driving disc that can move between a locking position and a pop-up position, and also includes a driving arm group located between the driving disc and the trailer body. The trailer body is placed in a different state by controlling the driving disc to be in different positions. For example, when the driving disc is in the locking position, the driving arm group can be used to lock the trailer body with six degrees of freedom to prevent the trailer from shaking due to vehicle bumps and abnormalities caused by shaking; when the driving disc is in the locking position, the trailer body can be popped out by the driving arm group. In this way, the pop-up and locking of the trailer body can be effectively controlled by the driving arm group, thereby realizing a simple and effective drive control method.

[0035] In some embodiments of the present application, a flange 110 is fixed to the side of the trailer body 100, and the driving arm group includes a plurality of driving arms 200 with the same structure;

[0036] One end of each driving arm 200 is a connecting end, which is rotatably connected to the driving plate 300 , and the other end is a movable end, which is pop-up connected to the flange 110 of the trailer body 100 .

[0037] It is understandable that when each driving arm 200 has one movable end, the embodiment of the present application includes more than three driving arms, and the trailer body can be locked with six degrees of freedom through more than three driving arms. When each driving arm has more than two movable ends (in this case, each movable end can be connected to a different position of the flange in a pop-up manner), the function of the driving arm group in the present application can also be implemented by providing one driving arm or two driving arms.

[0038] In some possible implementation schemes of the present embodiment, the number of the driving arms 200 is three, and the connection ends of the three driving arms 200 are evenly distributed on the circumferential side wall of the driving disk 300 .

[0039] like Figure 6 As shown, the circumferential side wall of the driving disk 300 has three evenly distributed connecting portions 310 , the angle between adjacent connecting portions 310 is 120°, and the connecting ends of the three driving arms 200 are rotatably connected to the connecting portions 310 .

[0040] The "pop-up connection" can be understood as that when the trailer body is in a locked state, the movable end of each driving arm 200 is firmly connected to the flange; when the trailer body is in a pop-up state, the movable end of each driving arm 200 pops out from the flange, and at this time the movable end is detached from the flange, and the two are in an unconnected state.

[0041] In some embodiments of the present application, the driving arm 200 includes a driving rod 210 and a driving claw 220, one end of the driving rod 210 is the connecting end, one end of the driving claw 220 is the movable end, the other end of the driving rod 210 is rotatably connected to the other end of the driving claw 220, and the driving claw 220 is provided with a fixed position 222, and the driving arm 200 is fixed to the trailer body 400 through the fixed position 222, and the driving claw 220 is rotatable relative to the fixed position 222.

[0042] The term "rotatably connected" may be understood as a connection point where one of the interconnected components can rotate relative to another component, for example, Figure 5 and Figure 6 As shown, the driving rod 210 can rotate counterclockwise relative to the connecting portion of the driving disk 300 , the other end of the driving rod 210 can rotate counterclockwise relative to the driving claw 220 , and the movable end can rotate counterclockwise relative to the fixed position 222 .

[0043] It should be noted that Figure 5 and Figure 6 The rotation direction is related to the moving direction of the driving disk. When the driving disk moves to the ejection position, the rotation direction is counterclockwise, and when the driving disk moves to the locking position, the rotation direction is clockwise.

[0044] In order to realize the rotatable connection relationship between the above components, the embodiment of the present application rotatably connects one end of the driving rod 210 to the connecting portion 310 of the driving disk 300 through the first rotating connector 231, rotatably connects the other end of the driving rod 210 to the other end of the driving claw 220 through the second rotating connector 232, and rotatably connects the driving claw 220 to the trailer body 400 at the fixed position of the driving claw 220 through the third rotating connector 233. It can be understood that in actual applications, the two rotatably connected components can also be implemented by a rotating connector, and the rotating connector or rotating connector is usually composed of two connectors and a freely rotatable rotating shaft.

[0045] In some embodiments of the present application, the movable end has a ball head 221, and the flange 110 includes a track that cooperates with the ball head 221, and the ball head 221 can be popped out and embedded in the track.

[0046] In some embodiments of the present application, the track is an annular track located on the circumferential side wall of the flange 110 .

[0047] In this embodiment, the pop-up connection between the driving arm 200 and the trailer body 100 is implemented by means of a ball head 221 and a circular track. When the trailer body 100 is in a locked state, the ball head 221 is tightly embedded in the circular track; when the trailer body 100 is in a pop-up state, the ball head 221 slides out of the circular track and detaches from the circular track.

[0048] In order to prevent the ball head 221 from interfering with the trailer body 100 when sliding out of the annular track, the other end of the driving claw 220 of the embodiment of the present application is staggeredly connected to the ball head 221. Figure 2 or Figure 5 As shown, the ball head 221 and the other end of the driving claw 220 (ie, the end where the fixing position is located) form a bent or stepped structure to prevent the driving claw from interfering with the side wall of the trailer body.

[0049] Combination Figure 3 and Figure 4 As shown, the driving principle of the main body driving structure in the embodiment of the present application is as follows:

[0050] When the drive disc moves from the locking position to the ejecting position under the action of the external force F1, each drive arm of the drive arm group is linked, and the three rotary connectors mentioned above rotate counterclockwise in turn, causing the ball head of each drive arm to rotate in accordance with Figure 4 The drive arm slides out of the circular track in the direction of the solid arrow in the middle. When the drive disc moves to the pop-up position, the ball head of each drive arm will be completely separated from the flange, and during the sliding of the ball head, the trailer body will pop out and slide out of the trailer body under the thrust of the ball head.

[0051] When the driving plate moves from the pop-up position to the locking position under the action of external force F2 (opposite to F1, not shown in the figure), each driving arm of the driving arm group is linked, and the three rotating connectors rotate clockwise in turn, causing the ball head of each driving arm to slide toward the annular track of the flange. When the driving plate moves to the locking position, the ball head of each driving arm will be completely embedded in the annular track of the flange, and the six-degree-of-freedom locking of the trailer body is completed under the action of multiple driving arms.

[0052] An embodiment of the present application also provides a transport vehicle, which includes a trailer and a trailer body, wherein the structure of the trailer is referred to above and will not be repeated herein in the embodiment of the present application.

[0053] The trailer body of the embodiment of the present application is provided with a fixing piece that cooperates with the driving arm, and the fixing position of each driving arm of the trailer is rotatably connected to the fixing piece of the trailer body through a third rotating connecting piece.

[0054] In addition, the trailer body of the embodiment of the present application is also provided with a sliding track, and the trailer body can slide along the sliding track.
