[0002] The power unit of a forklift is the core component of the forklift, responsible for providing driving force for driving, lifting, and steering. It mainly includes two categories: internal combustion system and electric system. Electric power system: relies on battery (such as DC series motor) to drive, converting electrical energy into mechanical energy. It has the advantages of being environmentally friendly and having low noise, and is suitable for short-distance indoor handling. The forklift battery is an energy storage device that provides power to the electric forklift. It converts chemical energy into electrical energy to drive the equipment through an electrochemical reaction. Therefore, a forklift battery structure that is easy to fix is ​​particularly needed.

[0003] However, in the existing forklift battery structures that are easy to fix, most forklift batteries are often fixed with bolts during installation. This operation requires tools and is cumbersome. At the same time, bolt stripping is also prone to occur, affecting the installation and removal of forklift batteries. Summary of the Invention

[0004] The purpose of this utility model is to provide a forklift battery structure that is easy to fix, in order to solve the problem mentioned in the background art that the existing forklift battery structures that are easy to fix are often fixed with bolts during use. This operation requires tools and is cumbersome. At the same time, the bolts are prone to stripping, which affects the installation and disassembly of the forklift battery.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forklift battery structure that is easy to fix, comprising a battery body and a fixing mechanism, wherein a fixing frame is provided on the surface of the battery body, heat dissipation holes are provided on the surface of the fixing frame, a shock-absorbing pad is bonded to the inner wall of the fixing frame, and a fixing mechanism is provided inside the fixing frame; The fixing mechanism includes a movable groove, a fixing block is fitted inside the movable groove, a return spring is fixedly connected to one end of the fixing block, a limit rod is fixedly connected to one end of the fixing block, a connecting rod is fixedly connected to one end of the fixing block, and a pull ring is fixedly connected to the other end of the connecting rod.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-4This utility model provides a technical solution: a forklift battery structure that is easy to fix, including a battery body 1 and a fixing mechanism 5. A fixing frame 2 is provided on the surface of the battery body 1, and heat dissipation holes 3 are opened on the surface of the fixing frame 2. A shock-absorbing pad 4 is bonded to the inner wall of the fixing frame 2. The fixing mechanism 5 is provided inside the fixing frame 2. The battery body 1, as the core unit of energy storage, achieves physical protection and mechanical positioning through the fixing frame 2. Its surface directly contacts the shock-absorbing pad 4 to buffer vibration and impact. The fixing frame 2 provides a rigid support frame for the battery body 1. The internal fixing mechanism 5 enables quick assembly and disassembly. The shock-absorbing pad 4 is made of sponge material to absorb high-frequency vibration during forklift operation and prevent the battery body 1 from hard contacting the fixing frame 2, which could cause the shell to crack. The fixing mechanism 5 includes a movable groove 501, a fixing block 502 is fitted inside the movable groove 501, a return spring 503 is fixedly connected to one end of the fixing block 502, a limit rod 504 is fixedly connected to one end of the fixing block 502, a connecting rod 505 is fixedly connected to one end of the fixing block 502, and a pull ring 506 is fixedly connected to the other end of the connecting rod 505. Through the arrangement of the movable groove 501, fixing block 502, return spring 503, limit rod 504, connecting rod 505, and pull ring 506, in... During use, when it is necessary to install and fix the battery body 1, the pull ring 506 can be pulled. Since one end of the connecting rod 505 passes through the fixing frame 2 and is connected to the pull ring 506, and the other end is fixedly connected to the fixing block 502, and one end of the fixing block 502 is fitted inside the movable groove 501, pulling the pull ring 506 can drive the fixing block 502 to move into the movable groove 501 through the connecting rod 505. Since the return spring 503 is set inside the movable groove 501 and its two ends are respectively fixed... The frame 2 and the fixed block 502 are fixedly connected. At the same time, the limiting rod 504 is set inside the movable groove 501 and its two ends are fixedly connected to the fixed frame 2 and the fixed block 502 respectively. When the fixed block 502 moves into the movable groove 501, the return spring 503 is compressed and deformed, and the limiting rod 504 retracts. When the fixed block 502 is fully engaged in the movable groove 501, the battery body 1 can be placed inside the fixed frame 2. Then, the force applied to the pull ring 506 is released. At this time, the return spring 503 rebounds and deforms. The rebounding return spring 503 drives the fixed block 502 to return to its original position. At this time, the fixed block 502 can fix the battery body 1 inside the fixed frame 2. When it is necessary to remove the battery body 1, the pull ring 506 can be pulled to make the fixed block 502 fully engaged in the movable groove 501. Thus, the fixed block 502 loses its limiting effect on the battery body 1, so the battery body 1 can be easily removed. The overall battery body 1 disassembly and assembly operation is simple and quick.

[0016] Furthermore, the shock-absorbing pad 4 is made of sponge material. By utilizing its porous elastic structure, the shock-absorbing pad 4 effectively absorbs the vibration energy generated during forklift travel or operation, preventing direct transmission of vibration to the battery body 1. This isolation reduces the risk of electrode plate damage and prevents electrolyte leakage, thereby extending battery life. The shock-absorbing pad 4, adhered to the inner wall of the fixing frame 2, forms a flexible wrapping layer. When the battery is subjected to external impacts (such as road bumps or cargo collisions), the sponge material disperses the impact force through deformation, reducing mechanical wear on the battery casing. Combined with the limiting function of the fixing mechanism 5, a dual protection mechanism of "rigid fixing + flexible protection" is formed. The shock-absorbing pad 4 fills the gap between the battery body 1 and the fixing frame 2, eliminating assembly gaps. Its compression and rebound characteristics ensure a tight fit of the battery within the fixing frame 2, preventing loosening due to micro-displacement during operation and ensuring reliable electrical connections.

[0017] Furthermore, the movable groove 501 is formed on the inner side wall of the fixed frame 2. Through the setting of the movable groove 501, the fixed block 502 is accommodated and guided to move during use. The movable groove 501 serves as a sliding track for the fixed block 502, constraining the fixed block 502 to move horizontally only in a specific direction, avoiding deviation or tilting, and ensuring the accuracy of the clamping action. A return spring 503 is installed inside the movable groove 501, providing a stable support point for the return spring 503, so that the return spring 503 can effectively drive the fixed block 502 to move towards the battery body 1, realizing the automatic locking function.

[0018] Furthermore, two sets of return springs 503 are provided and installed inside the movable groove 501. The end of the return spring 503 away from the fixed block 502 is fixedly connected to the fixed frame 2. Through the setting of the return spring 503, during use, the return spring 503 drives the fixed block 502 to continuously press upward towards the battery body 1 through the elastic force generated in the pre-compression state, thereby realizing the automatic fixation of the battery body 1. When disassembly is required, the connecting rod 505 is pulled by the pull ring 506 to overcome the spring force and unlock. After being released, the return spring 503 automatically returns to its initial position.

[0019] Furthermore, two sets of limiting rods 504 are provided. The limiting rods 504 are telescopic rods. Through the setting of the limiting rods 504, during use, the limiting rods 504 act as telescopic rods, rigidly connecting the fixed block 502 and the inner wall of the movable groove 501, constraining the fixed block 502 to move only in a straight line in the horizontal direction, preventing it from shifting or rotating during vibration or operation. The stroke range of the limiting rods 504 strictly limits the maximum displacement of the fixed block 502. When the pull ring 506 is released, the limiting rods 504 extend to their limit length to prevent the fixed block 502 from disengaging from the movable groove 501, thus avoiding disintegration of the mechanism.

[0020] Furthermore, one end of the connecting rod 505 passes through the fixed frame 2 and is fixedly connected to the pull ring 506. The connecting rod 505, as a rigid transmission component, directly transmits the manual pulling force of the external pull ring 506 to the fixed block 502, driving the fixed block 502 to overcome the elastic force of the reset spring 503 and move horizontally in the movable groove 501, thereby realizing the rapid unlocking of the battery.

[0021] Working Principle: The battery body 1 serves as the core energy storage unit. It is physically protected and mechanically positioned via the fixed frame 2. Its surface directly contacts the shock-absorbing pad 4 to buffer vibration and impact. The fixed frame 2 provides a rigid support frame for the battery body 1, and integrates a fixing mechanism 5 for quick assembly and disassembly. The shock-absorbing pad 4 uses sponge material to absorb high-frequency vibrations during forklift operation, preventing the battery body 1 from breaking due to hard contact with the fixed frame 2. When the battery body 1 needs to be installed and fixed, the pull ring 506 can be pulled. Since one end of the connecting rod 505 passes through the fixed frame 2 and connects to the pull ring 506, and the other end is fixedly connected to the fixing block 502, and one end of the fixing block 502 is embedded inside the movable groove 501, pulling the pull ring 506 can move the fixing block 502 into the movable groove 501 via the connecting rod 505. The return spring 503 is located inside the movable groove 501 and its two ends are fixedly connected to the fixed frame 2 and the fixing block 502 respectively, while also providing a limit. The rod 504 is located inside the movable groove 501 and its two ends are fixedly connected to the fixed frame 2 and the fixed block 502, respectively. When the fixed block 502 moves into the movable groove 501, the return spring 503 is compressed and deformed, and the limiting rod 504 retracts. When the fixed block 502 is fully engaged inside the movable groove 501, the battery body 1 can be placed inside the fixed frame 2. Then, the force applied to the pull ring 506 is released, and the return spring 503 rebounds and deforms. The rebounding return spring 503 drives the fixed block 502 back to its original position. At this time, the fixed block 502 can fix the battery body 1 inside the fixed frame 2. When it is necessary to remove the battery body 1, the pull ring 506 can be pulled to make the fixed block 502 fully engaged inside the movable groove 501. Thus, the fixed block 502 loses its limiting effect on the battery body 1, and the battery body 1 can be easily removed. The overall battery body 1 disassembly and assembly operation is simple and quick.
