[0020] The specific workflow of the moving body 1 from the vehicle compartment to the ground plane is as follows: the moving body 1 can be moved to the door frame of the compartment through the moving assembly, and the upper lifting support 2 is longitudinally slid relative to the moving body 1 and extended out of the door frame, and the lower lifting support 3 is moved downward and against the ground plane by means of the outward extension of the telescopic hinge assembly, and then the moving body 1 can be longitudinally moved relative to the upper lifting support 2 to move out of the vehicle compartment, and then the telescopic hinge assembly is retracted inwardly to allow the moving body 1 to stably descend and fall on the ground plane, and finally when the telescopic hinge assembly is retracted inwardly to the extreme value, the lower lifting support 3 can move upward to contact and separate from the ground plane. Correspondingly, the specific workflow of the moving body 1 from the ground plane to the vehicle compartment is opposite to the above workflow sequence.

[0021] The utility model has a simple structure, reasonable design and low cost. With the help of an upper lifting support 2 that slides longitudinally relative to the mobile body 1, and a telescopic hinge assembly that can drive the upper lifting support 2 and the lower lifting support 3 to move up and down, the mobile body 1 can be enabled to get on and off the vehicle between the connecting carriage and the ground, thereby effectively reducing the labor intensity of manually carrying goods up and down and reducing labor costs.

[0022] Among them, the telescopic hinge assembly can adopt a common combination structure of four hinge rods, that is, the hinge rods are combined in pairs and cross-hinged, the corresponding ends of the two groups of hinge rods are hinged to each other, and the outer ends of the two groups of hinge rods are respectively hinged to the upper lifting support 2 or the lower lifting support 3. In this embodiment, the telescopic hinge assembly includes a hinge bracket 1 5 and a hinge bracket 2 6 that are cross-arranged and hinged in the middle, the upper end of the hinge bracket 1 5 is hinged to the upper lifting support 2, the lower end of the hinge bracket 1 5 is horizontally slidably matched on the lower lifting support 3, the lower end of the hinge bracket 2 6 is hinged to the lower lifting support 3, and the upper end of the hinge bracket 2 6 is horizontally slidably matched on the upper lifting support 2, and one end of the telescopic power source 4 is hinged to the upper lifting support 2, and the other end is hinged to the hinge bracket 1 5 or the hinge bracket 2 6 or the lower lifting support 3.

[0023] In order to ensure that the mobile body 1 can move stably when getting on and off the vehicle, parallel supporting longitudinal rods 7 are longitudinally arranged on the left and right sides of the bottom surface of the mobile body 1, and the lifting upper support 2 is located between the two supporting longitudinal rods 7, and the left and right sides of the lifting upper support 2 are respectively slidably matched with the corresponding supporting longitudinal rods 7.

[0024] In order to make the longitudinal movement length of the upper lifting support 2 and the lower lifting support 3 longer and ensure that the lower lifting support 3 can move longitudinally to the corresponding side of the moving component, the supporting longitudinal rod 7 and the corresponding side wall of the upper lifting support 2 are slidably matched through the telescopic guide rail 8.

[0025] Furthermore, the moving component may adopt a crawler structure, and in the present embodiment, the moving component is a moving roller 9, and two or more connecting seats 10 are arranged at intervals on the left and right sides of the bottom surface of the moving vehicle body 1, and the moving roller 9 is rotatably engaged with each connecting seat 10.

[0026] At the same time, in order to facilitate the longitudinal movement of the upper lifting support 2 and the lower lifting support 3, the left and right side walls of the rear end of the lower lifting support 3 are respectively extended outward to form an extended push-pull portion 11.

[0027] In addition, a push-pull handle 12 is provided on the mobile body 1 .

[0028] The above embodiment is only one of the preferred embodiments of the present utility model, and is not intended to limit the scope of implementation of the present utility model. Therefore, any equivalent changes made based on the shape, structure, and principle of the present utility model should be included in the protection scope of the present utility model.
