Description

Technical Field

[0001] This utility model relates to the field of lithium battery electrode fixing technology, specifically a split lithium battery electrode fixing structure. Background Technology

[0002] Lithium-ion batteries are widely used in mobile electronic devices, electric vehicles, and energy storage systems due to their high energy density, low self-discharge rate, long lifespan, and low internal resistance. One of their core structural components is the electrode, which includes the positive electrode and the negative electrode. The performance of the electrode directly affects the energy storage and release efficiency of the lithium-ion battery.

[0003] However, in some existing lithium battery electrode fixing structures, the connection between the electrode and the mounting component is not tight enough. Fixation is achieved by the mounting shell being slightly larger than the electrode size, without any additional anti-slip or fixing design. During the use of lithium batteries, the electrode is prone to displacement due to vibration or shaking, reducing the overall stability. Furthermore, the four corners of the electrode are prone to deformation due to excessive compression, thus affecting the normal use of the electrode. Utility Model Content

[0004] The purpose of this invention is to provide a separate lithium battery electrode fixing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a split-type lithium battery electrode fixing structure, including lithium battery electrode sheets and mounting shells slidably connected to both sides thereof, and further comprising:

[0006] Several heat dissipation holes are opened at the bottom of the mounting shell, and several first anti-slip particles are fixedly connected to the surfaces of the upper and lower inner walls of the mounting shell. Guide grooves are opened on the upper and lower surfaces of one side of the mounting shell.

[0007] A fixed plate is slidably connected to the inner cavity of the mounting shell. A connecting plate is fixedly connected to the surface of the fixed plate. A sliding block is slidably connected to the surface of the connecting plate. Positioning grooves are provided on both sides of the surface of the connecting plate. Positioning blocks are fixedly connected to the bottom of the sliding blocks.

[0008] Preferably, two limiting blocks are fixedly connected to the other two sides of the fixing plate, and a limiting groove is formed in the inner wall of the mounting shell, and the surface of the limiting block is slidably connected to the inner wall of the limiting groove.

[0009] Preferably, a plurality of second anti-slip particles are fixedly connected to both sides of the fixing plate. The second anti-slip particles are hemispherical in shape and made of rubber.

[0010] Preferably, the mounting shell has a C-shaped cross-section and is used in conjunction with the lithium battery cell electrode.

[0011] Preferably, the sliding block has an L-shaped cross-section, and the surface of the sliding block is slidably connected to the inner wall of the mounting shell.

[0012] Preferably, the first anti-slip particle is made of rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, through the design of the first anti-slip particle and the mounting shell, facilitates the fixation of the lithium battery cell electrode, thereby ensuring the stable position of the lithium battery cell electrode even in complex working environments. This effectively reduces the performance degradation or safety hazards that may be caused by displacement, greatly improving the operational reliability and stability of the overall structure. The cooperation between the connecting plate and the sliding block further enhances the connection between the lithium battery cell electrode and the mounting shell, preventing the mounting shell from easily detaching from the surface of the lithium battery cell electrode. This effectively improves the protection of the lithium battery cell electrode and solves the problem of poor self-protection and easy damage in existing structures during use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-6As shown, the split-type lithium battery electrode fixing structure includes a lithium battery cell electrode 1, which is one of the core components of the lithium battery. Its performance directly determines the energy density, charge / discharge efficiency, and cycle life of the lithium battery. Mounting shells 2 are slidably connected to both sides of the lithium battery cell electrode 1. The mounting shells 2 have a C-shaped cross-section and work in conjunction with the lithium battery cell electrode 1. The mounting shells 2 protect the lithium battery cell electrode 1, effectively reducing the risk of damage from collisions. Several heat dissipation holes 3 are provided on the surface and bottom of the mounting shells 2. The heat dissipation holes 3 are frustoconical in shape, enhancing the heat exchange efficiency between the air and the interior of the mounting shells 2 and improving heat dissipation performance. The surfaces of the upper and lower inner walls of the mounting shells 2 are fixedly connected... Several first anti-slip particles 4 are attached, made of rubber and hemispherical in shape, which increases the friction between the mounting shell 2 and the lithium battery electrode 1, making the lithium battery electrode 1 more stable inside the mounting shell 2 and reducing the possibility of the lithium battery electrode 1 shaking. Guide grooves 5 are provided on both the upper and lower surfaces of one side of the mounting shell 2. The guide grooves 5 are designed with an inclined structure, which guides the lithium battery electrode 1 as it slides into the mounting shell 2, allowing it to enter the mounting shell 2 more smoothly and accurately along a predetermined trajectory, reducing installation difficulty and improving installation efficiency. A fixing plate 6 is slidably connected to the inner cavity of the mounting shell 2, and the fixing plate 6 can apply pressure to the lithium battery electrode 1 installed inside the mounting shell 2. To ensure stability and prevent displacement due to shaking, a connecting plate 8 is fixedly connected to the surface of the fixing plate 6, and a sliding block 9 is slidably connected to the surface of the connecting plate 8. The sliding block 9 has an L-shaped cross-section and its surface is slidably connected to the inner wall of the mounting shell 2, facilitating operator movement. When it is necessary to fix the lithium battery electrode 1 inside the mounting shell 2, the operator presses down on the sliding block 9, causing the connecting plate 8 to drive the fixing plate 6 to fit tightly against the surface of the lithium battery electrode 1. Simultaneously, the operator moves the sliding block 9 to one side, allowing a portion of it to enter the inner cavity of the mounting shell 2, thus fixing the lithium battery electrode 1 and reducing the possibility of displacement due to vibration or shaking during use, thereby improving overall stability. To ensure stability and reliability, several second anti-slip particles 7 are fixedly connected to both sides of the fixed plate 6. The second anti-slip particles 7 are hemispherical in shape and made of rubber, which has good elasticity. This effectively prevents the fixed plate 6 from naturally slipping out of the inner cavity of the mounting shell 2 when the structure is not in use, ensuring the safety and integrity of the structure during storage and transportation. Positioning grooves 10 are provided on both sides of the surface of the connecting plate 8, and positioning blocks 11 are fixedly connected to the bottom of the sliding blocks 9. The surface of the positioning blocks 11 is slidably connected to the inner wall of the positioning grooves 10. The cooperation between the positioning blocks 11 and the positioning grooves 10 guides the sliding blocks 9 during movement, making the sliding blocks 9 more stable.Two limiting blocks 13 are fixedly connected to the other two sides of the fixed plate 6. Four limiting grooves 12 are provided on the inner wall of the mounting shell 2. The surface of the limiting blocks 13 is slidably connected to the inner wall of the limiting grooves 12. The cooperation between the limiting blocks 13 and the limiting grooves 12 guides the fixed plate 6 during movement, thus making the fixed plate 6 more stable during movement.

[0024] Working principle: First, the lithium battery electrode 1 is slid into the inner cavity of the mounting shell 2 along the guide groove 5. Under the action of the first anti-slip particle 4 fixedly connected in the inner cavity, the friction between the mounting shell 2 and the lithium battery electrode 1 is increased, allowing the lithium battery electrode 1 to be initially stabilized in the mounting shell 2 and reducing shaking. Then, the operator presses down the sliding block 9 to drive the connecting plate 8 and the fixing plate 6 to move downward, so that the bottom of the fixing plate 6 is tightly attached to the surface of the lithium battery electrode 1. At this time, the sliding block 9 is moved to one side so that a part of it enters the inner cavity of the mounting shell 2, thereby blocking the sliding block 9 and the mounting shell 2 from each other, thus fixing the lithium battery electrode 1. This reduces the possibility of displacement of the lithium battery electrode 1 due to vibration or shaking during use, and improves the overall stability and reliability. When the structure is not used, the second anti-slip particle 7 made of rubber can effectively prevent the fixing plate 6 from naturally slipping in the inner cavity of the mounting shell 2, ensuring the safety and integrity of the structure during storage and transportation.
