[0053] In actual use, when the user carries a lot of items, the extension portion 2433 can be moved away from the connecting portion 2411, so that the first plug block 242 is disengaged from the first through hole 2121 and the second plug block 244 is disengaged from the second through hole 2221, and the positioning member 24 can be removed from the surrounding frame 21 and the bottom plate 22. Similarly, each positioning member 24 on the frame body 211 can be removed in turn to release the positioning state between the surrounding frame 21 and the bottom plate 22. At this time, the bottom plate 22 drives the connecting rod 23 to move away from the surrounding frame 21 under the action of gravity, thereby expanding the storage space of the basket 2 and can be used to place more items.

[0054] When the passenger carries a child, the basket 2 is positioned between the two movable plates 10 with the opening facing downward. Then, according to the size of the child, each positioning member 24 can be removed from the surrounding frame 21 and the bottom plate 22 to release the positioning state between the surrounding frame 21 and the bottom plate 22, and the plate body 221 is moved until the height of the plate body 221 matches the size of the child. The extension portion 2433 is rotated to align the boss 19 with the groove 2421, and then the insert block 1 242 and the insert block 244 are aligned with the through hole 231 located above the surrounding frame 21 and closest to the surrounding frame 21. Then, the extension portion 2433 is moved close to the connecting portion 2411, so that the boss 19 is inserted into the groove 2421, and the insert block 1 242 and the insert block 244 are penetrated with the through hole 231. The above operation is performed on each connecting rod 23 in turn. At this time, the connecting block 1 241 and the connecting block 243 abut against the frame 211, so that the plate body 221 can be positioned to meet the riding needs of children of different sizes.

[0055] See also Figures 1-11 The plug block 1 242, the transition portion 2412 and the connecting portion 2411 are spliced ​​to form a slot 3 20, the plug block 244, the extension portion 2433 and the sliding portion 2431 are spliced ​​to form a slot 4 25, the openings of the slot 3 20 and the slot 4 25 are opposite, a clearance hole 2113 is opened on the outer wall of the frame 211, the clearance hole 2113 is for the plug block 1 242 and the transition portion 2412 to pass through, the slot 3 20 is for the frame 211 to be inserted into, and an elastic strip 26 is fixed on the outer wall of the frame 211 near the clearance hole 2113. When the frame 211 is inserted into the slot 3 20, the elastic strip 26 is used to be inserted between the connecting portion 2411 and the extension portion 2433. In this embodiment, the elastic strip 26 is made of rubber.

[0056] In actual use, when the user carries items in plastic bags or bags and other objects that can be hung, the extension part 2433 can be rotated so that the plug block 1 242 and the plug block 244 are respectively located on the opposite sides of the rotation axis of the extension part 2433, and then the plug block 1 242 and the transition part 2412 are penetrated with the clearance hole 2113, and then the positioning member 24 is moved to make the frame 211 inserted into the card slot 3 20. At this time, the extension part 2433 and the plug block 244 are located on the outside of the frame 21 and can be used to hook items in plastic bags or bags and other objects.

[0057] The implementation principle of a shared electric vehicle that can improve driving safety in the embodiment of the present application is as follows:

[0058] When the weight of the items in the basket 2 is heavy, the positioning block 6 is flipped so that the positioning block 6 is disengaged from the positioning groove 2112, and then the basket 2 is moved to remove the basket 2 from the frame 1. Then, the positioning block 28 is flipped to overcome the effect of the elastic member 29 and the dovetail block 25 is slidably inserted into the dovetail groove 2111 until the positioning block 28 and the positioning groove 2112 are aligned. Then, the positioning block 28 is released. Under the action of the elastic member 29, the positioning block 28 is inserted into the positioning groove 2112 to realize the installation and positioning of the basket 2 on the tail frame 3. The transfer of the basket 2 is completed, and the weight of the basket 2 and the items therein are transferred to the tail of the electric vehicle, thereby reducing the influence on the user's control of the front of the vehicle, improving the sensitivity, accuracy and stability of the control of the front of the vehicle, and thus improving the driving safety of the shared electric vehicle when the weight of the items in the basket 2 is heavy.

[0059] If necessary, when the user carries a child, the basket 2 can be removed from the frame 1, and then the two movable plates 10 can be moved away from each other, and then the basket 2 with the opening facing downward can be placed between the two movable plates 10, so that the two movable plates 10 and the dovetail grooves 2111 are aligned, and then the movable plates 10 are moved so that the two movable plates 10 are respectively inserted into the corresponding dovetail grooves 2111 and the movable plates 10 are positioned, so that a seat can be provided for the child to sit on. At this time, the movable plates 10 can be used to place the user's feet. During the driving of the shared electric vehicle, the stability and safety of the child's riding are improved, and it is convenient for parents to carry their children to travel in the shared electric vehicle.

[0060] 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.
