[0030] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] Embodiment 1: The present application embodiment discloses a frame connection structure, such as Figure 1 and 2 As shown, the vehicle comprises a sub-frame 1, on which a sidecar is mounted, a first connecting rod 11 is fixedly connected to one side of the front portion of the sub-frame 1, a first ball joint 111 is fixedly connected to one end of the first connecting rod 11 away from the sub-frame 1, and the first ball joint 111 is rotatably connected to the main frame. When the vehicle turns, the main frame will tilt, and the sub-frame 1 is rotatably connected to the main frame through the setting of the first ball joint 111. Even if the main frame tilts, the sub-frame 1 is not affected by the tension generated by the tilt of the main frame, thereby reducing the possibility of the sub-frame 1 tilting.

[0033] like Figure 2As shown, the first connecting rod 11 is provided with a first reinforcing rod 112, which is arranged obliquely, and one end of the first reinforcing rod 112 is rotatably connected to the main frame, and the other end is rotatably connected to the first connecting rod 11. The first reinforcing rod 112 can improve the connection stability between the first connecting rod 11 and the main frame, and facilitate the main frame to drive the movement of the first connecting rod 11, thereby facilitating the main frame to drive the movement of the sub-frame 1.

[0034] like Figure 2 As shown, a second connecting rod 12 is rotatably connected to one side of the rear portion of the sub-frame 1, and a second ball joint 121 is fixedly connected to one end of the second connecting rod 12 away from the sub-frame 1, and the second ball joint 121 is rotatably connected to the main frame. The second connecting rod 12 can improve the connection stability between the sub-frame 1 and the main frame, thereby improving the stability of the sub-frame 1 during driving, and further reducing the possibility of the sub-frame 1 rolling over.

[0035] like Figure 2 As shown, the second connecting rod 12 is provided with a second reinforcing rod 122, the second reinforcing rod 122 is arranged obliquely, one end of the second reinforcing rod 122 is rotatably connected to the sub-frame 1, and the other end is rotatably connected to the second connecting rod 12. The second reinforcing rod 122 can improve the connection stability between the second connecting rod 12 and the sub-frame 1, thereby improving the connection stability between the main frame and the sub-frame 1, and facilitating the main frame to drive the sub-frame 1 to move.

[0036] like Figure 1 , 2 As shown in Figure 3, the auxiliary frame 2 is detachably connected to the sub-frame 1, and the auxiliary plate 21 is connected to the auxiliary frame 2 by bolts. The first connecting plate 13 is fixedly connected to the sub-frame 1, and the second connecting plate 22 is fixedly connected to the auxiliary frame 2. The first connecting plate 13 and the second connecting plate 22 fit together, and the first connecting plate 13 and the second connecting plate 22 are connected by bolts. When the auxiliary frame 2 needs to be installed, the operator can move the auxiliary frame 2 to drive the movement of the second connecting plate 22, so that the second connecting plate 22 fits with the first connecting plate 13, and then screw in the bolts to fix the first connecting plate 13 and the second connecting plate 22, thereby achieving the installation of the auxiliary frame 2. The fixed installation of the auxiliary frame 2 can make the auxiliary plate 21 relatively fixed to the sub-frame 1, and the auxiliary plate 21 can be used by the operator, such as placing sundries or taking daily meals, etc., which improves the driving experience of the operator.

[0037] The implementation principle of a frame connection structure in the embodiment of the present application is: When the vehicle turns, the main frame will tilt. The first ball joint 111 and the second ball joint 121 are arranged to make the sub-frame 1 and the main frame rotationally connected. Even if the main frame tilts, the sub-frame 1 is not affected by the tension generated by the tilt of the main frame, thereby reducing the possibility of the sub-frame 1 tilting. The operator can install the auxiliary frame 2 on the sub-frame 1, thereby realizing the installation of the auxiliary plate 21. The auxiliary plate 21 can be used by the operator in daily life, thereby improving the practicality of the vehicle.

[0038] Embodiment 2: like Figure 4 and 5 As shown, the difference between the embodiment of the present application and the first embodiment is that the rear of the auxiliary frame 1 is fixedly connected with a support plate 3, the auxiliary frame 2 is rotatably connected to the support plate 3, and baffles 23 are fixedly connected to both sides of the auxiliary frame 2. A lifting plate 4 is provided on the auxiliary frame 1 and is located between the support plate 3 and the side bucket and slides relatively in the vertical direction. A control component 5 for controlling the sliding of the lifting plate 4 is provided on the auxiliary frame 1. When the auxiliary plate 21 is not needed, the operator can rotate the auxiliary frame 2 to abut against the support plate 3, and control the rise of the lifting plate 4 through the control component 5. At this time, the auxiliary plate 21, the support plate 3, the baffle 23 and the lifting plate 4 can form a storage space for the operator to place the items they carry, thereby improving the practicality of the vehicle.

[0039] like Figure 4 and 5 As shown, the control assembly 5 includes a contact sensor 51 and a control cylinder 52. The support plate 3 is provided with a mounting groove 31. The contact sensor 51 is installed in the mounting groove 31. The notch of the mounting groove 31 is rotatably connected with a protective cover 32. The protective cover 32 can protect the contact sensor 51 and reduce the possibility of the contact sensor 51 being accidentally touched. The contact sensor 51 and the control cylinder 52 are connected by wires. The control cylinder 52 is fixedly installed on the sub-frame 1. The piston rod of the control cylinder 52 is fixedly connected to the lifting plate 4. When the auxiliary plate 21 is not needed, the operator can rotate the auxiliary frame 2 to make the auxiliary frame 2 rotate to abut against the support plate 3. At this time, the rotating frame contacts the contact sensor 51. The contact sensor 51 activates the control cylinder 52 through the wire, so that the piston rod of the control cylinder 52 drives the lifting plate 4 to move. At this time, the storage space formed by the auxiliary plate 21, the support plate 3, the baffle 23 and the lifting plate 4 can be used to place items.

[0040] like Figure 4 and 5As shown, a storage slot 41 is provided on the top of the support plate 3, a drawstring 42 is fixedly connected to the wall of the storage slot 41, a draw hook 43 is installed at one end of the drawstring 42, and a draw ring 33 is fixedly connected to one side of the support plate 3, and the draw hook 43 is embedded in the draw ring 33. When the auxiliary frame 2 rotates to abut against the support plate 3, the operator can pull out the drawstring 42 to embed the draw hook 43 in the draw ring 33. The drawstring 42 can apply force to the auxiliary frame 2 to reduce the possibility of the auxiliary frame 2 flipping over when the sub-frame 1 is driving. The drawstring 42 can also protect the items carried by the operator to reduce the possibility of the items falling.

[0041] The implementation principle of a frame connection structure in the embodiment of the present application is: When the auxiliary plate 21 is not needed, the operator can rotate the auxiliary frame 2 backward so that the auxiliary frame 2 rotates to abut against the support plate 3. At this time, the rotating frame contacts the contact sensor 51, and the contact sensor 51 starts the control cylinder 52 through the electric wire, so that the piston rod of the control cylinder 52 drives the movement of the lifting plate 4. At this time, the auxiliary plate 21, the support plate 3, the baffle 23 and the lifting plate 4 can form a storage space for the operator to place the items they carry. The pull rope 42 can apply force to the auxiliary frame 2 to reduce the possibility of the auxiliary frame 2 flipping over when the sub-frame 1 is traveling. The pull rope 42 can also protect the items carried by the operator to reduce the possibility of the items falling.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
