[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0024] An electric vehicle frame with a dual-effect tail box, such as Figures 1 to 7 As shown, the vehicle includes a frame body 1. Two oppositely arranged mounting plates 2 are provided at the rear end of the frame body 1. A tail box 3 is movably connected to the two mounting plates 2. The tail box 3 can rotate or slide relative to the two mounting plates 2.
[0025] Specifically, both sides of the tail box 3 are provided with connectors 6, and both mounting plates 2 are provided with corresponding strip holes 7 for connectors 6. Connectors 6 are movably inserted through strip holes 7. Strip holes 7 are opened along the length direction of mounting plates 2. Connectors 6 can slide along strip holes 7 or rotate relative to strip holes 7. It should be noted that in this embodiment, connectors 6 are threaded to tail box 3, which facilitates the disassembly and assembly of connectors 6 and makes it convenient for later maintenance and replacement.
[0026] The tail box 3 and the mounting plate 2 are spaced apart. Both connecting parts 6 are threaded with positioning nuts 18. The two positioning nuts 18 can abut against the outer surface of the corresponding mounting plate 2, thereby achieving relative stability between the tail box 3 and the mounting plate 2.
[0027] The tail box 3 can be rotated to a horizontal or vertical position and remain stable. Fasteners 8 can be detachably connected to both mounting plates 2, and the fasteners 8 can keep the tail box 3 and the mounting plates 2 relatively stable.
[0028] Specifically, both mounting plates 2 are provided with several adjustment holes 9, which are evenly distributed along the length of the strip hole 7. The tail box 3 is provided with positioning hole 10 and positioning hole 21. When the tail box 3 is in a vertical state, the fastener 8 can pass through any one of the adjustment holes 9 and be threaded to the positioning hole 10. When the tail box 3 is in a horizontal state, the fastener 8 can pass through any one of the adjustment holes 9 and be threaded to the positioning hole 21. By restricting the connector 6 through the strip hole 7 and by restricting the fastener 8 through the adjustment holes 9 in conjunction with the positioning holes 10 or 21, the stability of the tail box 3 in a horizontal or vertical state is ensured.
[0029] Specifically, when the tail box 3 is in a vertical position, its position is adjusted by sliding, and then the fastener 8 passes through the corresponding adjustment hole 9 and is threaded to the positioning hole 10 to achieve positioning. When the tail box 3 is in a horizontal position, its position is adjusted by sliding, and then the fastener 8 passes through the corresponding adjustment hole 9 and is threaded to the positioning hole 11 to achieve positioning.
[0030] The tail box 3 has a lid end face 5 and two oppositely arranged box side faces 4. The area of the two box side faces 4 is larger than the area of the lid end face 5. When the tail box 3 is in a vertical state, the lid end face 5 faces upward in the vertical direction, and one of the box side faces the front end of the frame body 1. When the tail box 3 is in a horizontal state, the lid end face 5 faces the front end of the frame body 1, and the other box side face 4 faces upward in the vertical direction. When the tail box 3 is in a horizontal or vertical state, it can slide closer to or further away from the rear end of the frame body 1.
[0031] When the tail box 3 is in a vertical position, it can be used as a backrest to provide reliable support for the passenger, thereby ensuring the passenger's safety and comfort. When the tail box 3 is in a horizontal position, it can be used as a support for the carried items, which not only effectively ensures that the rear of the frame body 1 has sufficient loading space, but also improves the stability of the carried items.
[0032] Furthermore, when the tail box 3 is used as a support for the carried items, the larger side surface 4 of the box contacts the carried items, thereby increasing the support area for the items and further improving the stability of the carried items.
[0033] It should be noted that by adjusting the state of the tailgate 3, it can be used as a backrest for passengers or a support for items, meeting the needs of different scenarios and making it convenient for users.
[0034] One of the boxes has a backrest pad 12 detachably mounted on its side 4, and the other box has a cushioning pad 13 detachably mounted on its side 4. In this embodiment, the backrest pad 12 is made of memory foam and the cushioning pad 13 is made of rubber.
[0035] The backrest cushion 12, made of memory foam, comes into contact with the back of the passenger. The memory foam can adapt to the deformation of the human back, thereby effectively dispersing back pressure and improving riding comfort. The cushioning pad 13, made of rubber, comes into contact with the carried items. The cushioning pad 13 can effectively absorb and disperse vibration energy, preventing damage to the items or trunk 3 due to vibration during vehicle operation, and further ensuring the stability of the items when the vehicle is traveling on complex road conditions.
[0036] One of the side panels 4 of the box has a hook-and-loop fastener 14, and the backrest cushion 12 has a loose-fitting hook-and-loop fastener 15. The hook-and-loop fastener 14 and the loose-fitting hook-and-loop fastener 15 correspond to each other. The tight fit between the hook-and-loop fastener 14 and the loose-fitting hook-and-loop fastener 15 ensures the relative stability of the tail box 3 and the backrest cushion 12. At the same time, this method also makes it easier to install and remove the backrest cushion 12, which is conducive to the maintenance and replacement of the backrest cushion 12 in the future.
[0037] Another side panel 4 of the box is equipped with hook-and-loop fastener 16, and the cushioning pad 13 is equipped with loose-fitting hook-and-loop fastener 17. The hook-and-loop fastener 16 and the loose-fitting hook-and-loop fastener 17 correspond to each other. The tight fit between the hook-and-loop fastener 16 and the loose-fitting hook-and-loop fastener 17 ensures the relative stability of the tail box 3 and the cushioning pad 13. At the same time, this method also makes it easier to install and remove the cushioning pad 13, which is conducive to the maintenance and replacement of the cushioning pad 13 in the future.
[0038] The working principle of this utility model is as follows:
[0039] When the state of the tail box 3 needs to be adjusted, first turn the two positioning nuts 18 away from the corresponding mounting plate 2, then turn the two fasteners 8 to remove them. After that, the tail box 3 can be rotated or moved by external force. Then, the fasteners 8 are passed through the corresponding adjustment holes 9 and threaded to the positioning hole 10 or positioning hole 21. Finally, turn the two positioning nuts 18 to make them abut against the mounting plate 2.
[0040] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
