It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0028] As Figures 1 to 7 shown, the battery swapping forklift frame system of this embodiment includes a battery swapping frame 1. Two battery swapping cavities 2 are arranged from top to bottom at the front end of the battery swapping frame 1. The battery swapping cavities 2 are used for placing battery swapping battery boxes. A connection plug 3 is installed on the battery swapping frame 1 at the rear of the interior of the battery swapping cavity 2. The connection plug 3 is used to connect with the socket of the battery swapping battery box to realize the connection between the battery swapping battery box and the electric forklift equipment circuit. Support plates 4 are installed on both sides inside the battery swapping frame 1 below the battery swapping cavities 2. A plurality of roller assemblies are installed on the support plates 4. The roller assemblies are used to support the bottom end of the battery swapping battery box, and the roller assemblies can drive the battery swapping battery box to move. A limiting assembly is commonly installed inside the battery swapping frame 1 between the fronts of the two battery swapping cavities 2. The limiting assembly is used to limit the battery swapping battery box to prevent the battery swapping battery box from accidentally sliding out of the interior of the battery swapping cavity 2. A rotating rod 7 is rotatably connected to the limiting assembly. The setting of the rotating rod 7 facilitates driving the limiting assembly to rotate.

[0029] Specifically, the roller assembly includes a mounting shaft 501, a bearing assembly 502, and a roller body 503. Bearing assemblies 502 are installed at both ends of the roller body 503. Mounting shafts 501 are rotatably connected inside the bearing assemblies 502. The mounting shafts 501 are detachably installed on the support plates 4. The roller body 503 is installed on the support plates 4 through the mounting shafts 501. The roller body 503 can rotate through the bearing assemblies 502 to realize the rotation of the roller body 503. The rotation of the roller body 503 can move the battery swapping battery box, and the roller body 503 also supports the battery swapping battery box.

[0030] Further, the support plate 4 is U-shaped. Installation grooves 8 are provided at the upper ends of both sides of the support plate 4. The installation grooves 8 are U-shaped. Planes 9 are provided on the front and rear parts of the surface of the installation shaft 501. The installation shaft 501 is installed inside the installation groove 8. The planes 9 on the installation shaft 501 are respectively in contact with the front and rear ends inside the installation groove 8. The roller body 503 extends above the support plate 4. When the battery swapping box is installed into the battery swapping cavity 2 and taken out from the inside of the battery swapping cavity 2, the movement of the battery swapping box drives the roller body 503 to rotate. The roller body 503 is installed through the installation shaft 501. The planes 9 on the surface of the installation shaft 501 effectively prevent the installation shaft 501 from sliding when supporting the roller body 503.

[0031] Further, the limiting component includes a mounting plate 601, a rotating shaft 602, a threaded block 603 and a limiting plate 604. The mounting plate 601 is installed at the rear of the battery swapping frame 1 between the fronts of the two battery swapping cavities 2. A rotating shaft 602 is rotatably connected between the front end of the mounting plate 601 and the battery swapping frame 1 through a bearing member. Threads are provided on the surface of the rotating shaft 602. A threaded block 603 is threadedly connected to the surface of the rotating shaft 602. A limiting plate 604 is installed at the front end of the threaded block 603. The limiting plate 604 is sleeved on the surface of the rotating shaft 602. The front end of the rotating shaft 602 extends outside the battery swapping frame 1. The rotating rod 7 is hingedly installed at the front end of the rotating shaft 602. By rotating the rotating rod 7, the rotating shaft 602 is driven to rotate. The rotating shaft 602 drives the threaded block 603 to move. The threaded block 603 drives the limiting plate 604 to rotate. When the limiting plate 604 rotates 90°, the two battery swapping boxes can be blocked and limited simultaneously. And after the rotation of the limiting plate 604 ends, continuously rotating the rotating rod 604 can continuously drive the limiting plate 604 to continue to move, facilitating the movement of the limiting plate 7 towards and away from the battery swapping box.

[0032] Further, a left fixing plate 12 is installed at the upper end of the mounting plate 601 on one side of the limiting plate 604, and a right fixing plate 13 is installed at the lower end of the mounting plate 601 on the other side of the limiting plate 604. The limiting plate 604 is installed between the left fixing plate 12 and the right fixing plate 13. The left fixing plate 12 is used to keep the limiting plate 604 in a vertical state, and the right fixing plate 13 is used to keep the limiting plate 604 in a horizontal state, facilitating the control of the state of the limiting plate 604. And the limiting plate 604 is always located between the left fixing plate 12 and the right fixing plate 13, avoiding the phenomenon that the limiting plate 604 always rotates following the rotating shaft 602.

[0033] Further, protective pads 14 are installed above and below the rear end of the limiting plate 604. Limiting blocks are installed at the rear ends inside the two battery swapping cavities 2 on both sides of the connection plug 3. Protective blocks 11 are installed at the front ends of the limiting blocks. The protective pads 14 and the protective blocks 11 are used to limit the front and rear ends of the battery swapping box, facilitating the connection between the socket on the battery swapping box and the equipment connection plug 3, and effectively preventing the battery swapping box from shaking back and forth.

[0034] Further, one end of the rotating rod 7 is hingedly installed with a handle 15. A storage board 16 is installed at the front end of the battery swapping frame 1 on one side of the rotating shaft 602. The storage board 16 is L-shaped. The connection part of the handle 15 and the rotating rod 7 is located inside the storage board 16. The setting of the handle 15 forms a Z shape with the handle 15, the rotating rod 7 and the rotating shaft 602, which facilitates multi-turn rotation of the rotating shaft 602. Moreover, the setting of the storage board 16 facilitates the storage and placement of the handle 15 and the rotating shaft 602.

[0035] Further, the battery swapping frame 1 is installed with a forklift housing 18. A battery swapping door 19 is installed at the front end of the forklift housing 18. A door lock 20 is installed on the battery swapping door 19. The setting of the battery swapping door 19 facilitates the protection of the battery swapping frame 1. The setting of the door lock 20 effectively prevents the battery swapping door 19 from being accidentally opened, ensuring the safety of the battery swapping battery box and avoiding the phenomenon that the battery swapping battery box is stolen by lawbreakers.

[0036] Furthermore, guiding pads 21 are installed at both ends inside the battery swapping cavity 2. Guiding blocks 22 are installed on both sides in front of the bottom end inside the battery swapping cavity 2. Guiding surfaces 17 are arranged on the opposite surfaces of the front ends of the two guiding pads 21 and the two guiding blocks 22. The guiding pads 21 are used for soft contact with both ends of the battery swapping battery box, playing a protective role. The guiding surfaces 17 on the guiding pads 21 and the guiding blocks 22 facilitate the battery swapping battery box to be inserted into a proper position, facilitating the alignment and connection of the socket on the surface of the battery swapping battery box and the connecting plug 3.

[0037] The usage method of this embodiment is as follows: When using this battery swapping forklift frame system, open the battery swapping door 19 to expose the battery swapping cavity 2. Then, take out the handle 15 and the rotating rod 7 from the storage plate 16, form a Z shape with the handle 15, the rotating rod 7 and the rotating shaft 602, and rotate the handle 15 to rotate the mounting shaft 501. The rotating shaft 602 drives the limiting plate 604 to rotate through the threaded block 603. When the limiting plate 604 changes from the vertical state to the horizontal state, then store the handle 15 and the rotating rod 7 inside the storage plate 16 again. The external moving device moves the battery swapping battery box inside the battery swapping cavity 2, so that the socket of the battery swapping battery box and the connecting plug 3 are separated, take out the used battery swapping battery box, and put in the unused battery swapping battery box. During this process, the surface of the guide roller body 503 contacts the bottom end of the battery swapping battery box, and the guide roller body 503 rotates following the movement of the battery swapping battery box, which facilitates the movement of the battery swapping battery box. After the unused battery box is placed inside the battery swapping cavity 2, use the handle 15 to drive the rotating shaft 602 to rotate in the reverse direction again. The rotating shaft 602 drives the limiting plate 604 to rotate, so that the limiting plate 604 changes from the horizontal state to the vertical state. The limiting plate 604 limits the battery swapping battery boxes inside the two battery swapping cavities 2. As the rotating shaft 602 continues to rotate, the limiting plate 604 approaches the battery swapping battery box. At the same time, the battery swapping battery box compresses the protective pad 14 and the protective block 11. Store the rotating rod 7 and the handle 15 inside the storage plate 16, and then close the battery swapping door 19, that is, complete the replacement of the battery swapping battery box.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
