These screws are made of corrosion-resistant alloy material, providing strong fixing force while being easy to disassemble and maintain, ensuring efficient assembly and stability of the battery pack 1. Multiple waterproof connectors 106 are fixedly connected to the top of the battery cover 103. The connector structure is precisely designed with excellent waterproof performance, ensuring the safety of the battery pack 1 in various operating environments.

[0036] One side of the discharge interface 109 is fixedly connected to one side of the waterproof connector 106. This interface is designed in accordance with industrial standards and can transmit electrical energy stably and efficiently, ensuring the normal operation of the forklift. The bottom of the access port 105 is fixedly connected to the top of the battery cover 103. The access port 105 facilitates quick access to the inside of the battery pack 1 for maintenance, simplifies the maintenance process, and improves the overall ease of operation.

[0037] The waterproof sealing strip 104 is externally pressed and connected to the side of the battery cover 103 and the access port 105, which further enhances the waterproof sealing performance of the battery pack 1 and ensures that it can still operate normally in harsh environments.

[0038] The counterweight block 2 is detachably connected to the inner wall of the battery pack 1. Its stable connection design ensures the stability of the battery pack 1 during operation and improves the safety of the forklift during operation.

[0039] Two fixing strips 3 and multiple fixing screws 4 are used to connect the counterweight box block 2 and the battery pack 1. The fixing strips 3 and fixing screws 4 are made of high-strength materials, providing excellent shock resistance and durability, ensuring the stability and safety of the entire battery swapping device in long-term use.

[0040] Counterweight box block 2 includes:

[0041] PACK module 201 is externally fixed to the inner wall of the counterweight box block 2. This module adopts a modular design, which facilitates installation and maintenance and ensures the efficient operation of the battery system.

[0042] Module 202 is connected in series. The left end of module 202 is fixedly connected to the right end of PACK module 201. This series structure is optimized to ensure stable current transmission throughout the battery system and improve overall efficiency.

[0043] Module series connection 203 is fixedly connected to the right end of PACK module 1 201 at its left end. Together with module series connection 202, it works to ensure stable and reliable electrical connection between battery modules and further improve system safety.

[0044] PACK Module 204 is fixedly connected to the bottom of PACK Module 1 201 at its top. This module uses high-density battery cells and can provide powerful power output to support the continuous operation of the forklift in high-intensity operations.

[0045] Electrical module 205 is fixedly connected to the left end of PACK module 204 at its right end. The module integrates multiple protection functions, including overcurrent, overvoltage and overtemperature protection, to ensure the safe operation of the system under various operating conditions.

[0046] The electrical panel 205 is externally mounted on the inner wall of the battery casing 101, and the external part of PACK module two 204 is fixedly connected to the inner wall of PACK module one 201. The tight connection between the components improves the stability and safety of the entire system. One end of module series one 202 and module series two 203 is fixed to the positive terminal of PACK module two 204, and the other end of module series one 202 and module series two 203 is fixed to the negative terminal of PACK module one 201, forming a complete electrical circuit to ensure stable power output and continuous operation of the equipment.

[0047] Waterproof sealing strip 104 is pressed together by positioning screw 108 to ensure a tight seal, preventing external moisture from entering and ensuring long-term reliable system operation. Antenna 107 works with electrical board 205 to upload data to the cloud, ensuring real-time and accurate remote monitoring and improving the intelligent management level of the equipment. Waterproof connector 106 is used at the wire harness exit point; its design ensures that the wire harness exit point has a high degree of waterproof capability, further improving the overall reliability of the system.

[0048] Working principle: Install PACK module 204 inside the battery casing 101 and fix it in place. One end of module series connection 202 and module series connection 203 is fixed to the positive terminal of PACK module 204.

[0049] Subsequently, PACK module 1 201 is installed into and secured to battery casing 101. The other end of module 201 (connected in series) and module 202 (connected in series) are then fixed to the negative terminal of BPACK module 1 201, forming a series connection for the entire device. At this point, electrical board 205 is installed into battery casing 101. Once the battery is connected to electrical board 205, it provides multiple protection functions including overcurrent, overvoltage, and overtemperature protection. Simultaneously, it supports cloud-based monitoring of battery pack 1's status, allowing users to conveniently view real-time battery operating information and detect any abnormalities.

[0050] Waterproof adhesive strip 102 is pressed between the battery casing 101 and the battery cover 103, while waterproof adhesive strip 104 is pressed between the battery cover 103 and the battery access port 105. Positioning screws 108 are used for pressing, and waterproof connectors 106 are used at the wiring harness exit points to ensure normal operation of the equipment in rainy conditions. Antenna 107 works in conjunction with electrical board 205 to upload data to the cloud, while the battery discharges through discharge interface 109. Furthermore, the universal battery pack 1 is designed to be suitable for multiple forklift models, and is fixed to the counterweight block 2 using fixing screws 4. The counterweight block is designed according to the dimensions of the forklift battery compartment to ensure that it can adapt to different forklift models without affecting the forklift's counterweight, thus achieving standardization of battery pack 1.

[0051] When the forklift battery is low, the forklift can quickly drive into the battery swapping station to replace battery pack 1. Without moving or replacing the counterweights, simply replacing battery pack 1 quickly restores the forklift to normal operation. The entire battery swapping process is convenient and efficient, significantly reducing downtime caused by battery replacement.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
