[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 4 A foldable and retractable electric vehicle rear rack includes a rear rack body 1, with a mounting frame 2 rotatably connected to the rear rack body 1. A carrying plate 3 is located at the movable end of the mounting frame 2. The mounting frame 2 can rotate to switch the carrying plate 3 between a horizontal and a vertical position. When the carrying plate 3 is in a horizontal position, it is located below the rear rack body 1 and used to support goods. When the carrying plate 3 is in a vertical position, it is located at the rear of the rear rack body 1 and can be used as a backrest. This allows users to control the position and state of the carrying plate 3 as needed, thereby achieving different functions and meeting the usage needs in different scenarios.

[0022] Specifically, the rear shelf body 1 includes a central crossbar 101 distributed along the width direction of the rear shelf body 1, and the mounting frame 2 is rotatably connected to the central crossbar 101 so that the mounting frame 2 can be flipped around the central crossbar 101, thereby changing the state of the carrying plate 3.

[0023] Furthermore, the mounting bracket 2 includes two L-shaped movable rods 201. One end of each movable rod 201 is fixedly provided with a rotating part 202. The rotating part 202 is rotatably mounted on the outside of the middle crossbar 101. The rotating part 202 is fixed to the middle crossbar 101 by a fixing bolt 203. The two movable rods 201 are fixedly connected by a connecting rod.

[0024] The rotating part 202 is fixedly connected to one end of the movable rod 201. The rotating part 202 is symmetrically distributed on the middle crossbar 101, and the middle crossbar 101 passes through the rotating part 202 and is rotatably connected to the rotating part 202. The two ends of the connecting rod are fixedly connected to the two movable rods 201 respectively, so that the two movable rods 201 are connected as a whole, and the two movable rods 201 can rotate synchronously.

[0025] On the other hand, threaded holes for inserting fixing bolts 203 are provided on both the rotating part 202 and the middle crossbar 101. The fixing bolts 203 are threaded into the threaded holes of the rotating part 202. When the fixing bolts 203 are screwed into the threaded holes on the middle crossbar 101, the rotating part 202 can be fixed, thereby fixing the flipping angle of the movable rod 201 and thus fixing the state of the carrying plate 3.

[0026] In this embodiment, the carrier plate 3 is detachably connected to the movable ends of the two movable rods 201, so that a user can perform maintenance and replacement on the carrier plate 3, thereby prolonging the service life of the device.

[0027] Further, positioning frames 204 are fixedly arranged on the side surfaces of the movable ends of the two movable rods 201 respectively. The positioning frames 204 are C-shaped, and the openings of the two positioning frames 204 are arranged facing each other. The carrier plate 3 is slidably embedded inside the two positioning frames 204, so as to facilitate disassembly and assembly of the carrier plate 3.

[0028] Wherein, when the carrier plate 3 and the positioning frame 204 are connected by interference fit, the frictional resistance between the carrier plate 3 and the inner side of the positioning frame 204 is relatively large. Specifically in this embodiment, when the force applied by the user to the carrier plate 3 along the length direction of the positioning frame 204 is greater than 10N, the carrier plate 3 can be driven to slide inside the positioning frame 204. When the interference fit connection is not used between the carrier plate 3 and the positioning frame 204, threaded holes can be opened on the positioning frame 204 and the carrier plate 3, and the installation and fixation of the carrier plate 3 can be completed through bolts or screws, which can be selected according to actual conditions.

[0029] In order to prevent goods from falling easily when stored on the carrier plate 3, in the present application, a plurality of strap hooks 205 are fixedly arranged on the side of the positioning frame 204. When the carrier plate 3 is in a horizontal state, the strap hooks 205 are located at the bottom of the positioning frame 204, presenting as Figure 1 the state shown, at this time, the user can wind an elastic strap around the strap hooks 205 to fix the goods on the carrier plate 3.

[0030] Further, when the user does not have many articles to store, the user can turn over the mounting frame 2 to make the carrier plate 3 in the state as Figure 2 the state shown, at this time, the overall space occupied by the mounting frame 2 is reduced, and the carrier plate 3 can be used as a backrest at the same time, so that the device has more functions.

[0031] It is worth mentioning that a storage slot 301 is provided on the side surface of the carrier plate 3. When the carrier plate 3 is in a vertical state, the storage slot 301 is located on the top surface of the carrier plate 3. At this time, the user can place paper documents or other thin articles in the storage slot 301. Meanwhile, a flip cover can be arranged at the opening of the storage slot 301, and the flip cover can be connected to the carrier plate 3 through a buckle to seal the storage slot 301, so as to avoid article loss.

[0032] The working principle and application process of the present utility model: first, when the user needs to carry a large number of articles, the mounting frame 2 needs to be turned over to the state as Figure 1As shown, the storage tray 3 is positioned below the rear shelf body 1 and is in a horizontal state. The rotating part 202 is fixed to the middle crossbar 101 using the fixing bolt 203, thus completing the fixing of the mounting bracket 2 and the storage tray 3. At this time, items can be placed on the upper surface of the storage tray 3 and secured with elastic straps wrapped around the strap hooks 205. Items can also be stored in the upper area of ​​the rear shelf body 1 using elastic straps.

[0033] When the user is carrying fewer items, the mounting bracket 2 can be flipped up to the desired position. Figure 2 The state shown allows the tray 3 to be located at the rear of the rear shelf body 1 and in a vertical position; at this time, goods can still be stored above the rear shelf body 1, and some paper documents can also be stored in the storage slot 301; at the same time, the tray 3 can also be used as a backrest.
