Detailed Description

In order to facilitate understanding of the technical solutions of the present invention, the following detailed description is made with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1, a collapsible and expandable DIY cart includes a universal base 100, a frame 200, and a housing 300.

The general base 100 is shown in fig. 2, and includes a chassis 110, front wheels and rear wheels 120 disposed at two ends of the chassis, a steering wheel 130, an accelerator, and a seat 140 disposed on the chassis, a battery and a motor disposed inside the chassis, and a steering mechanism 150 disposed below the chassis. The output end of the steering mechanism 150 is connected with the front wheels, and the input end is connected with the steering wheel and used for controlling the advancing direction of the trolley. The circuit connection diagrams of the battery, the motor and the like in the universal base and the more detailed structural schematic diagram are taken as the prior art, and are not repeated herein. Parts such as a steering wheel, a seat, wheels and the like can be expanded and replaced according to the actual requirements of users.

The framework 200 is schematically shown in FIG. 3, and comprises 4 vertical frameworks 210-240 and horizontal frameworks 250-260. The vertical frame 210 and 230 is in an inverted U shape, and the vertical frame 240 is fixedly connected with the center point of the vertical frame 230 through the hand-screwed screw 400 and the hand-screwed nut 500. The vertical frameworks 210 and 220 are distributed at the front end of the universal base, and the vertical frameworks 230 and 240 are distributed at the rear end of the universal base and fixed with the universal base 100 through hand-screwed screws 400. The transverse frameworks 250 and 260 and each vertical framework are provided with at least one connecting point which is connected with a hand-screwed nut through a hand-screwed screw, and the transverse frameworks and the vertical frameworks form the stable and reliable framework 200 together.

The shell 300 comprises a plurality of shell pieces 310 with flanging structures, a first decorating piece 320 and a second decorating piece 330, the shell pieces are spliced into the shell through buckles, the shell pieces 310 are made of plastics, corresponding unique numbers are arranged at positions where the appearance of the shell pieces is not affected, the shell pieces can be installed on the framework 200 according to the number sequence, and a corresponding vehicle type appearance can be spliced by one complete set of shell pieces. The number of pieces of the housing tile 310 varies according to the vehicle type. Taking fig. 8 as an example, the total number of the blocks is 18. Fig. 7 and 8 show that the colors and shapes of some shell tiles can be changed in a variety by replacement. The first decorative pieces 320 are wing-shaped members in this embodiment, and have spherical fasteners, corresponding slots are reserved on the housing fragments, the spherical fasteners are fastened into the slots to realize the fixed connection to the housing, and two first decorative pieces 320 are symmetrically arranged on the housing from left to right, as shown in fig. 10 and 11. As shown in fig. 9, the second decorative member is fixedly connected to the universal base 100 by a hand screw 400, and is fixedly connected to the frame 200 by a fastening structure 340.
