DETAILED DESCRIPTION

[0022] The utility model is further described in detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides a battery-swap battery box for an electric forklift, comprising an external fixed shell 1 and a battery box body 5, a top cover 2 is movably installed on the top of the external fixed shell 1, limiting slots 3 are fixedly installed at the four corners inside the external fixed shell 1, a buffer component 4 is fixedly installed inside the external fixed shell 1, the inner side of the limiting slot 3 is movably connected with the battery box body 5, the battery box body 5 is arranged on the inner side of the buffer component 4, and installation grooves 11 are opened on the left and right sides inside the external fixed shell 1, and a fixing component 6 is movably installed inside the installation groove 11.

[0024] The battery box body 5 is installed on the inner side of the limit slot 3 in the outer fixed shell 1, and the top cover 2 is installed on the top of the outer fixed shell 1 to compress the battery box body 5. The fixing components 6 on the left and right sides of the outer fixed shell 1 are respectively operated to make the fixing components 6 penetrate the outer fixed shell 1 and clamp the top cover 2 to limit and fix the top cover 2. The battery box body 5 is pressed by the top cover 2, so that the structure of the battery box body 5 is stable. The fixing components 6 are operated quickly to facilitate the installation and removal of the battery box body 5 and to facilitate quick replacement. At the same time, the buffer component 4 arranged inside the outer fixed shell 1 and the top cover 2 surrounds the battery box body 5 from the side, which plays an elastic buffer role for the battery box body 5 and plays a certain protective role.

[0025] like Figure 4 As shown, the fixing assembly 6 includes two threaded columns 61, which are rotatably installed at the front and rear sides of the installation groove 11 respectively, and the outer sides of the two threaded columns 61 are fixedly connected to the operating hand wheels 63 located outside the outer fixing shell 1, and the interior of the installation groove 11 is movably connected with a sliding plate 64, and a connecting hole 65 is opened inside the sliding plate 64. The sliding plate 64 is threadedly connected to the outside of the two threaded columns 61 through the connecting hole 65, and a clamping block 66 is fixedly connected to the inner side of the sliding plate 64.

[0026] By rotating the operating hand wheel 63 on the side of the outer fixed shell 1, the threaded column 61 located inside the installation groove 11 is driven to rotate synchronously by synchronously rotating the operating hand wheel 63. The sliding plate 64 located in the installation groove 11 and threadedly connected to the outside of the threaded column 61 is driven to slide outward by the synchronous rotation of the threaded column 61. The block 66 is driven by the sliding plate 64 to escape from the interior of the top cover 2 and be received into the installation groove 11. Then, the top cover 2 is removed from the top of the outer fixed shell 1, and the battery box main body 5 is removed from the top cover 2 for replacement, thereby facilitating the disassembly and replacement of the battery box main body 5.

[0027] like Figure 5 As shown, the buffer assembly 4 includes a lower buffer pad 41 movably connected to the inner side of the top cover 2, a support card plate 42 movably connected to the bottom of the outer fixed shell 1, the lower buffer pad 41 is arranged above the support card plate 42, an upper buffer pad 43 movably connected to the bottom of the top cover 2, and side limit grooves 44 are fixedly connected to the four sides inside the outer fixed shell 1, and side buffer pads 45 are movably connected inside the side limit grooves 44.

[0028] The battery box body 5 is pressed by the top cover 2 to ensure its stable fixation. The battery box body 5 is set on the supporting card plate 42. A lower buffer pad 41 is set at the bottom of the supporting card plate 42 to cooperate with the upper buffer pad 43 at the bottom of the top cover 2 to press the battery box body 5. At the same time, the side buffer pad 45 that fits the side of the battery box body 5 on the inner side of the external fixed shell 1 is used to limit and buffer the battery box body 5.

[0029] like Figure 3 and Figure 4 As shown, the left and right sides of the top cover 2 are both provided with fixing grooves 21 corresponding to the clamping blocks 66 .

[0030] The clamping block 66 penetrates through the inner side of the outer fixing shell 1 and is movably clamped in the fixing groove 21 .

[0031] The clamping block 66 passes through the outer fixing shell 1 and is clamped in the fixing groove 21 , so that the top cover 2 is fixed on the outer fixing shell 1 , which is convenient for disassembly and assembly of the top cover 2 and replacement of the battery box body 5 .

[0032] like Figure 4 As shown, the outer part of the threaded column 61 is movably sleeved with a support spring 62 located outside the sliding plate 64 .

[0033] The support spring 62 is arranged on the outer side of the sliding plate 64 to support the sliding plate 64 , thereby improving the stability when the sliding plate 64 moves with the threaded column 61 .

[0034] like Figure 3 and Figure 5As shown, a circular protrusion corresponding to the supporting clamping plate 42 is provided on the top of the lower buffer pad 41 , and the lower buffer pad 41 is movably clamped on the top of the supporting clamping plate 42 .

[0035] The battery box body 5 is disposed on the supporting card plate 42 , and the battery box body 5 is located inside the upper buffer pad 43 and the side buffer pad 45 .

[0036] The circular protrusion on the top of the lower buffer pad 41 corresponds to the support card plate 42, so that when the support card plate 42 carries the battery box body 5, the support card plate 42 is pressed down and the side buffer pad 45 is located on the side of the battery box body 5 to play an elastic buffering role, thereby improving the protection effect.

[0037] The following is a detailed description of the working principle of the battery-swap battery box for electric forklifts.

[0038] like Figures 1 to 5 As shown, the outer fixed shell 1 is located on the electric forklift, and the two operating hand wheels 63 corresponding to one side of the outer fixed shell 1 are rotated, and the two threaded columns 61 located inside the mounting groove 11 are driven to rotate synchronously by the synchronous rotation of the two operating hand wheels 63. The sliding plate 64 located in the mounting groove 11 and threadedly connected to the outside of the threaded column 61 is driven to slide outward by the synchronous rotation of the two threaded columns 61. The block 66 engaged in the fixing groove 21 is driven to be disengaged and received in the mounting groove 11 by the sliding plate 64. The fixing assembly 6 on the other side is disengaged by operating, and then the top cover 2 is removed from the top of the outer fixed shell 1. During disassembly, the battery box body 5 is removed from the top cover 2 for replacement, and then the top cover 2 is docked and snapped back to the top of the external fixed shell 1, and the fixing components 6 on both sides are operated respectively to make the clamping block 66 snap into the fixing groove 21 to limit and fix the top cover 2, and the battery box body 5 is pressed tightly by the top cover 2 to ensure its stable fixation, and the battery box body 5 is arranged on the supporting card plate 42, and the bottom of the supporting card plate 42 is provided with a lower buffer pad 41 to cooperate with the upper buffer pad 43 at the bottom of the top cover 2 to press the battery box body 5, and at the same time, the side buffer pad 45 that fits the side of the battery box body 5 on the inner side of the external fixed shell 1 is used to limit and buffer the battery box body 5.

[0039] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
