[0002] In the practice of converting forklifts from gasoline to electric, the battery pack, as the core power source, directly affects the forklift's operating efficiency due to its ease of battery swapping. Existing battery pack installation structures for converted forklifts mostly employ a fixed bracket design, requiring the battery pack to be rigidly connected to the bracket via multiple bolts. Battery swapping necessitates manual disassembly of each bolt, a cumbersome process. Furthermore, the battery pack itself is heavy and lacks auxiliary handling structures, requiring external equipment for transfer after disassembly, further extending swapping time and severely impacting the forklift's continuous operating capability. Therefore, this application proposes a battery pack installation structure for converted forklifts to address these issues. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1-3As shown, this utility model provides a technical solution: a battery pack installation structure for an electric forklift converted from gasoline, including a mounting frame 1 for supporting and positioning the battery pack 5. The mounting frame 1 is a frame structure with one side open. Several protective plates 2 are fixedly arranged along the side height direction on the outer walls of its three closed sides. Several heat dissipation gaps are formed between the several inclined protective plates 2. The inclined protective plates 2 can play a good protective role and also ensure heat dissipation.

[0021] The mounting frame 1 has an assembly port on the open side. A sealing plate 3 is installed at the bottom of the assembly port. The sealing plate 3 is set along the length of the mounting frame 1 and has a sliding groove inside. An extension plate 4 is adapted to slide in the sliding groove. The extension plate 4 can extend completely out of the sealing plate 3 along the sliding groove. When the extension plate 4 and the sealing plate 3 are unfolded, they together form a slide rail plate for assembling the battery pack 5.

[0022] A battery pack 5 for providing power is detachably installed inside the mounting frame 1 via an assembly port. A protective frame 6 for protecting the battery pack 5 is fixedly fitted onto the outer wall of the battery pack 5. The protective frame 6 is adapted to and fits snugly against the shape of the battery pack 5. Multiple pulleys 7 are rotatably mounted on both sides of the bottom end of the protective frame 6 via brackets. The pulleys 7 can roll along the surface of the extended plate 4 and the sealing plate 3 after being unfolded, so that the battery pack 5 and the protective frame 6 can be easily pushed in or pulled out as a whole. After the sealing plate 3 is opened, the extended plate 4 is pulled outward along the sliding groove of the sealing plate 3 until the extended plate 4 is fully extended, so that the extended plate 4 and the sealing plate 3 together form a complete slide rail. The battery pack 5 with the protective frame 6 fitted on it is placed at the end of the extended plate 4 away from the mounting frame 1, aligned with the assembly port. The battery pack 5 is pushed along the slide rail with the help of the pulleys 7 at the bottom end of the protective frame 6 until the outer wall of the protective frame 6 is tightly fitted with the limiting plate 9 inside the mounting frame 1, thus completing the positioning of the battery pack 5. When the battery pack 5 needs to be replaced, the power plug should be disconnected first. The sealing plate 3 and the extension plate 4 unfold to form a slide rail plate. The battery pack 5 and the protective frame 6 are pulled out as a whole, so that they can slide out of the mounting frame 1 along the sealing plate 3 and the extension plate 4. A power slot 8 that penetrates into the interior of the frame is opened in the middle of the top side of the mounting frame 1. The position of the power slot 8 corresponds to the power supply port on the top of the battery pack 5. The power plug of the forklift passes through the slot and connects to the power supply port of the battery pack 5. The forklift power plug passes through the power slot 8 on the top side of the mounting frame 1 and connects with the power supply port on the top of the battery pack 5. The battery pack 5 then supplies power to the forklift.

[0023] Multiple limiting plates 9 are fixedly installed inside the mounting frame 1. When the protective frame 6 is fully installed into the mounting frame 1 along with the battery pack 5, the outer side wall of the protective frame 6 is tightly fitted with the inner side wall of the four limiting plates 9 to limit the lateral displacement of the protective frame 6 and the battery pack 5 within the mounting frame 1. The tight fit between the outer side wall of the protective frame 6 and the limiting plates 9 inside the mounting frame 1 can complete the positioning of the battery pack 5 and ensure that the battery pack 5 is stably installed in the mounting frame 1. The mounting frame 1, protective plate 2, sealing plate 3 and protective frame 6 are all made of aluminum alloy, and the outer surface of each component is coated with an anti-rust and anti-corrosion coating.

[0024] The operational steps for this application are as follows:

[0025] After opening the sealing plate 3, pull the extension plate 4 outward along the sliding groove of the sealing plate 3 until the extension plate 4 is fully extended, so that the extension plate 4 and the sealing plate 3 together form a complete slide rail plate. Place the battery pack 5 with the protective frame 6 on the end of the extension plate 4 away from the mounting frame 1, align it with the assembly port direction, and push the battery pack 5 along the slide rail plate with the help of the pulley 7 at the bottom of the protective frame 6 until the outer wall of the protective frame 6 is tightly fitted with the limiting plate 9 in the mounting frame 1, thus completing the positioning of the battery pack 5.

[0026] Push the extension plate 4 to retract it completely into the sliding groove of the sealing plate 3, rotate the sealing plate 3 to seal it at the assembly port of the mounting frame 1, and lock it with the locking bolt; then pass the forklift power plug through the power slot 8 on the top side of the mounting frame 1 and connect it with the power supply port on the top of the battery pack 5, so that the battery pack 5 can power the forklift.

[0027] When the battery pack 5 needs to be replaced, first disconnect the power plug. The sealing plate 3 and the extension plate 4 are unfolded to form a slide rail. The battery pack 5 and the protective frame 6 are pulled out as a whole and slid out along the sealing plate 3 and the extension plate 4 to install the frame 1.
