Description

Technical Field

[0001] This utility model relates to the technical field of forklift batteries, and in particular to a forklift battery pack that is easy to maintain. Background Technology

[0002] Forklift battery packs are the core power unit of electric forklifts. They are composed of multiple batteries connected in series and parallel to provide the DC power required for the forklift to drive, lift, and perform other operations. Electric forklift battery packs are auxiliary devices installed on electric forklifts during logistics transportation to provide power and enable them to operate better. They have been widely used in the field of battery pack technology. Therefore, there is a particular need for a forklift battery pack that is easy to maintain.

[0003] However, most existing forklift battery packs are installed and fixed with bolts during use. When they need to be disassembled for maintenance, a lot of time and effort are often required for disassembly and assembly, which wastes time and reduces maintenance efficiency.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN217983577U that discloses a forklift battery pack designed for easy maintenance. The patent describes a system comprising: "a housing with a shock-absorbing plate slidably connected within it; a battery pack positioned on top of the shock-absorbing plate; rotating columns connected to the left and right sides of the top of the shock-absorbing plate via bearings; cavities within the rotating columns; and a clamping mechanism within each cavity. Adjustment mechanisms are also provided on the left and right sides of the top of the shock-absorbing plate. This invention, through the clamping mechanism, can clamp and secure the forklift battery pack, ensuring its stability within the housing." When the forklift battery needs maintenance, the clamping plate is separated from the forklift battery pack. Then, under the action of the adjustment mechanism, the rotating column is rotated, thereby rotating the clamping plate to both sides of the forklift battery pack. This makes it easy to remove the forklift battery pack from the box for maintenance, which is convenient and improves maintenance efficiency. Although the forklift battery can be installed and fixed through the clamping mechanism, and it is also convenient to remove the battery, maintenance personnel need to spend a lot of effort to rotate it. At the same time, the fixing is not stable, which affects the disassembly and assembly efficiency. In addition, relying solely on spring shock absorption cannot achieve the required shock absorption effect.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Summary of the Invention

[0006] The purpose of this utility model is to provide a forklift battery pack that is easy to maintain, in order to solve the problem mentioned in the background art that most existing forklift battery packs are often installed and fixed with bolts during use. When it is necessary to disassemble and maintain them, a lot of time and precision are often required for disassembly and assembly, which wastes time and reduces maintenance efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a forklift battery pack that is easy to maintain, comprising a housing, a battery body, and a clamping mechanism. The battery body is placed inside the housing, a damper is installed on the bottom surface of the housing, a limit rod is fixedly connected to the bottom surface of the housing, a shock-absorbing spring is sleeved on the surface of the limit rod, a support plate is fixedly connected to the top of the limit rod, and a clamping mechanism is provided inside the housing. The clamping mechanism includes a lifting groove, a limit groove is formed inside the housing, a synchronous motor is installed inside the housing, a one-way lead screw is installed inside the lifting groove, a lifting block is threaded on the surface of the one-way lead screw, limit blocks are fixedly connected to both ends of the lifting block, and a clamping plate is fixedly connected to one side of the surface of the lifting block.

[0008] Preferably, one end of the damper is fixedly connected to the support plate.

[0009] Preferably, the limiting rod is a telescopic rod, and the shock-absorbing spring is provided in two sets, with both ends fixedly connected to the outer shell and the support plate respectively.

[0010] Preferably, the limiting groove is a dovetail-shaped groove, and the limiting groove is connected to the lifting groove.

[0011] Preferably, the output end of the synchronous motor is fixedly connected to the unidirectional lead screw.

[0012] Preferably, the limiting block is a dovetail-shaped block, and the limiting block is fitted inside the limiting groove.

[0013] Preferably, the lifting block is fitted inside the lifting groove, and the clamping plate is disposed inside the outer casing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This easy-to-maintain forklift battery pack uses a synchronous motor to drive a unidirectional lead screw to control the lifting and lowering of the clamping plate to achieve automatic clamping / release of the battery body, replacing the traditional bolt fixing method. Disassembly can be completed without tools during maintenance, greatly improving efficiency. The dovetail-shaped limit block and the limit groove cooperate to ensure no deviation during the clamping process, avoiding the time-consuming manual adjustment. The damper absorbs low-frequency large-amplitude impacts (such as sudden braking and going over bumps) during forklift operation, and reduces the vibration amplitude of the battery through hydraulic energy consumption.

[0017] 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a forklift battery pack that is easy to maintain, including a shell 1, a battery body 2, and a clamping mechanism 7. The battery body 2 is placed inside the shell 1. A damper 3 is installed on the bottom surface of the shell 1. A limit rod 4 is fixedly connected to the bottom surface of the shell 1. A shock-absorbing spring 5 is sleeved on the surface of the limit rod 4. A support plate 6 is fixedly connected to the top of the limit rod 4. The clamping mechanism 7 is set inside the shell 1. The shell 1 serves as the main frame of the battery pack, providing mechanical support and protection. It integrates a shock absorption system and a clamping mechanism 7. The damper 3 is rigidly connected to the support plate 6 to absorb the impact energy during forklift operation and suppress the vertical vibration amplitude of the battery body 2. The limit rod 4 acts as a telescopic rod to constrain the vertical displacement range of the support plate 6 and prevent excessive shaking. The shock-absorbing spring 5 is sleeved on the surface of the limit rod 4 and buffers high-frequency vibration through elastic deformation. The two sets of shock-absorbing springs 5 ​​are symmetrically distributed to enhance stability. The clamping mechanism 7 includes a lifting groove 701, a limiting groove 702 inside the housing 1, a synchronous motor 703 installed inside the housing 1, a one-way lead screw 704 installed inside the lifting groove 701, a lifting block 705 threaded onto the surface of the one-way lead screw 704, limiting blocks 706 fixedly connected to both ends of the lifting block 705, and a clamping plate 707 fixedly connected to one side of the surface of the lifting block 705. Through the arrangement of the lifting groove 701, limiting groove 702, synchronous motor 703, one-way lead screw 704, lifting block 705, limiting block 706, and clamping plate 707, during use, when it is necessary to install and fix the battery body 2, the battery body 2 can be placed on the surface of the support plate 6 inside the housing 1, and then the synchronous motor 703 is turned on by the controller. Because the output end of the synchronous motor 703... The unidirectional lead screw 704 is fixedly connected to the synchronous motor 703, which drives the unidirectional lead screw 704 to rotate inside the lifting groove 701. Since the lifting block 705 is embedded inside the lifting groove 701 and threaded onto the surface of the unidirectional lead screw 704, and dovetail-shaped limiting blocks 706 are fixedly connected to both ends of the lifting block 705, the limiting blocks 706 are embedded inside the limiting groove 702. Thus, when the unidirectional lead screw 704 rotates, the lifting block 705 moves downward along the unidirectional lead screw 704 inside the lifting groove 701. At this time, the lifting block 705 drives the clamping plate 707 to install and fix the battery body 2. When the battery body 2 needs to be disassembled for maintenance, the battery body 2 can be removed simply by driving the unidirectional lead screw 704 to rotate in the opposite direction through the synchronous motor 703, causing the lifting block 705 to move upward.

[0019] Furthermore, one end of the damper 3 is fixedly connected to the support plate 6. As the core component of the shock absorption system, the damper 3 is rigidly connected to the support plate 6. Through internal hydraulic or friction mechanisms, it converts the impact kinetic energy generated during forklift travel into heat energy for dissipation, reducing the vibration amplitude of the battery body 2. It works in conjunction with the limit rod 4 to limit the vertical movement range of the support plate 6, preventing the battery from dislodging or colliding due to severe bumps. It complements the damping spring 5, which is responsible for buffering high-frequency small-amplitude vibrations (such as minor road bumps) and responds quickly through elastic deformation. The damper 3 is responsible for low-frequency large-amplitude impacts (such as sudden braking or going over bumps) and suppresses resonance through damping force, avoiding continuous shaking of the battery caused by the reciprocating oscillation of the spring. Compared with bolt fixing that relies on structural rigidity for vibration resistance, the introduction of the damper 3 realizes dynamic energy management, significantly reducing the risk of damage to the battery electrode plates caused by vibration and extending the battery cycle life.

[0020] Furthermore, the limiting rod 4 is a telescopic rod, and the shock-absorbing spring 5 is provided in two sets with its two ends fixedly connected to the outer shell 1 and the support plate 6 respectively. The limiting rod 4, as a telescopic rod, rigidly connects the outer shell 1 and the support plate 6, strictly limiting the vertical displacement range of the support plate 6, preventing the battery body 2 from moving due to overload caused by vibration or impact. Working together with the shock-absorbing spring 5, the spring buffers the vibration energy, while the limiting rod 4 avoids the spring from failing due to excessive compression or stretching by physically limiting it. Through the rod structure, it guides the support plate 6 to only make linear movements in the vertical direction, eliminating the risk of lateral swaying and ensuring the stability of the battery under bumpy conditions.

[0021] Furthermore, the limiting groove 702 is a dovetail-shaped groove, and the limiting groove 702 is connected to the lifting groove 701. Through the setting of the limiting groove 702, the limiting groove 702 can limit the limiting block 706 and provide it with sliding space.

[0022] Furthermore, the output end of the synchronous motor 703 is fixedly connected to the one-way lead screw 704. With the synchronous motor 703 in use, since the output end of the synchronous motor 703 is fixedly connected to the one-way lead screw 704, the synchronous motor 703 can drive the one-way lead screw 704 to rotate inside the lifting groove 701 when it is working.

[0023] Furthermore, the limiting block 706 is a dovetail-shaped block, which is fitted inside the limiting groove 702. By setting the limiting block 706, the limiting block 706 can limit the lifting block 705 during use, preventing the lifting block 705 from rotating with the one-way lead screw 704.

[0024] Furthermore, the lifting block 705 is fitted inside the lifting groove 701, and the clamping plate 707 is disposed inside the outer casing 1.

[0025] Working Principle: The outer casing 1 serves as the main frame of the battery pack, providing mechanical support and protection. Internally, it integrates a shock absorption system and clamping mechanism 7. The damper 3 is rigidly connected to the support plate 6, absorbing the impact energy during forklift operation and suppressing the vertical vibration amplitude of the battery body 2. The limiting rod 4 acts as a telescopic rod, constraining the vertical displacement range of the support plate 6 to prevent excessive swaying. Shock-absorbing springs 5 ​​are sleeved on the surface of the limiting rod 4, buffering high-frequency vibrations through elastic deformation. The two sets of shock-absorbing springs 5 ​​are symmetrically distributed to enhance stability. When it is necessary to install and fix the battery body 2, it can be placed on the surface of the support plate 6 inside the outer casing 1. Then, the synchronous motor 703 is turned on via the controller. Since the output end of the synchronous motor 703 is fixedly connected to the one-way lead screw 704, it... The stepper motor 703 drives the one-way lead screw 704 to rotate inside the lifting groove 701. Since the lifting block 705 is embedded inside the lifting groove 701 and threaded onto the surface of the one-way lead screw 704, and the lifting block 705 is fixedly connected to the two ends of the dovetail-shaped limiting block 706, which is embedded inside the limiting groove 702, when the one-way lead screw 704 rotates, the lifting block 705 moves downward along the one-way lead screw 704 inside the lifting groove 701. At this time, the lifting block 705 drives the clamping plate 707 to install and fix the battery body 2. When the battery body 2 needs to be disassembled for maintenance, the battery body 2 can be removed simply by driving the one-way lead screw 704 to rotate in the opposite direction through the synchronous motor 703, causing the lifting block 705 to move upward.
