[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] A trolley with a rear-opening door, see reference Figures 1-5 The vehicle includes a body, which includes wheels 6, a base plate 4, a front plate 2 and a rear plate 3 respectively disposed on both sides of the base plate 4, two side plates 5 disposed between the front plate 2 and the rear plate 3, and a handle 1 rotatably connected to the front plate 2. The base plate 4 is rotatably connected to the front plate 2, and the rear plate 3 is rotatably connected to the two side plates 5. When the rear plate 3 rotates, it rotates from a vertical state to an inclined state. A rotating rod 10 is rotatably connected to one end of the rear plate 3 near the side plates 5. A rotating shaft 11 is protruding from one end of the rotating rod 10 near the side plates 5. The rotating shaft 11 is rotatably connected to the rotating rod 10. The side plates 5 have movable grooves 12 for the rotating shaft 11 to move. The rear plate 3 is provided with a fixing structure for fixing the rear plate 3 and the side plates 5.

[0021] The bottom plate 4 is located at the very bottom and is rotatably connected to the front plate 2. As can be seen from the attached figure, the bottom plate 4 consists of two pieces. It can be rotated and folded from the position of the rear plate 3 to the position of the front plate 2. Then, by folding the side plates 5 at both ends, the front plate 2 and the rear plate 3 are brought closer to each other, thus folding the entire vehicle body.

[0022] When using the vehicle body, the bottom plate 4 is positioned between the front plate 2 and the rear plate 3, and the rear plate 3 has a part for the bottom plate 4 to be inserted into. However, when the rear plate 3 rotates, the part connected to the bottom plate 4 does not rotate with it but is fixed to the side plates 5 at both ends for the insertion of the locking blocks on the bottom plate 4. During the rotation of the rear plate 3, the rotating rod 10 between the rear plate 3 and the side plates 5 will rotate at the connection point between the rear plate 3 and the side plates 5 due to the rotation of the rear plate 3. A rotating shaft 11 is provided at the end of the rotating rod 10 near the side plate 5. As the rear plate 3 rotates, the rotating shaft 11 will always be located in the movable slot. The rotating rod 10 slides along the inner wall of the movable groove 12, causing the rotating shaft 11 to rotate between the rotating shaft 11 and the rear plate 3, thereby opening the rear plate 3. This allows the user to put items in through the rear opening of the vehicle body or to allow pets to enter the vehicle body through the rear opening, making it more convenient for the user. After the items are placed and the pet is in the vehicle, the rear plate 3 and the side plate 5 are finally fixed together by the fixing structure to prevent the rear plate 3 from rotating away from the side plate 5 during the vehicle's movement, which would cause the vehicle to become unstable.

[0023] Example 1: Refer to Figure 5 The fixing structure includes a spring block 13 protruding on the rear plate 3 and a slot 14 formed on the side plate 5, the slot 14 for the spring block 13 to be inserted.

[0024] When the back plate 3 rotates back to the vertical position, it moves closer to the side plate 5. The spring block 13 on the back plate 3 corresponds to the slot 14 on the side plate 5. The spring block 13 is a relatively mature existing technology, which is hemispherical and has good elasticity. When the spring block 13 is aligned with the slot 14, the spring block 13 will be locked into the slot 14 to fix it, thereby fixing the back plate 3 and the side plate 5. When the back plate 3 is separated from the side plate 5, the user only needs to pull the back plate 3 to separate it from the side plate 5. At the same time, magnets that can attract each other can be set in the spring block 13 and the side plate 5 respectively, so that when the spring block 13 is locked into the slot 14, the fixing effect and fixing force between the two can be increased.

[0025] Example 2: Refer to Figures 1-4 The difference between the fixed structure and the first and second embodiments is that the fixed structure includes a first slide rail 7 on the rear plate 3, a second slide rail 8 on the side plate 5, and a sliding block 9 slidably connected between the first slide rail 7 and the second slide rail 8. The sliding block 9 has an inner groove with the same shape as the first slide rail 7 and the second slide rail 8.

[0026] When the user needs to open the rear panel 3, they first need to slide the sliding block 9 so that it slides from the position of the second slide rail 8 onto the first slide rail 7 and completely disengages from the second slide rail 8. Then, both ends of the sliding block 9 slide onto the first slide rail 7, thus opening the rear panel 3 and the side panel 5. The user can then rotate the rear panel 3 and open the rear opening of the vehicle. The structure is simple and convenient for the user to operate. At this time, the user can put items in and pets can easily get in and out of the vehicle through the rear opening. After the items are placed and the pet is in the vehicle, the user can proceed with the operation. Then rotate the rear panel 3 so that it is close to the side panel 5 until the surface of the rear panel 3 is in contact with the inner wall of the side panel 5. Then, the user slides the sliding block 9 so that the sliding block 9 slides along the outer wall of the first slide rail 7 to the position close to the side panel 5 and slides into the position of the second slide rail 8. The sliding block 9 slides between the first slide rail 7 and the second slide rail 8, thereby locking the first slide rail 7 and the second slide rail 8, preventing the rear panel 3 from rotating on its own, making it convenient for the user to operate, and also making it easier to open the rear panel 3, and making it easier to load items and pets into the vehicle.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
