Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery technology, specifically to an anti-collision shell for lithium-ion batteries. Background Technology

[0002] Lithium-ion batteries are widely used in many fields, such as electronic devices, due to their high energy density and long cycle life. However, during transportation, lithium-ion batteries are susceptible to external forces such as collisions and compression. These forces may cause deformation of the battery casing, damage to the internal structure, or even lead to serious safety accidents such as short circuits, fires, and explosions. This not only damages the battery itself but may also pose a significant threat to the life and property safety of users.

[0003] During transportation, lithium-ion batteries are typically placed in protective cases to protect them from impacts. However, different models of lithium-ion batteries have different sizes, and existing protective cases are not suitable for positioning different models, resulting in significant limitations in their use. Therefore, it is necessary to redesign and modify the protective cases for lithium-ion batteries to effectively prevent these inconveniences. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a shockproof shell for lithium-ion batteries, which has the advantages of being easy to use and providing good protection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shockproof shell for lithium-ion batteries, comprising a base plate, a limiting rod fixedly connected to the top of the base plate, the number of limiting rods being several, a movable frame slidably connected to the surface of the limiting rod, a spring fixedly connected to the top of the base plate, the end of the spring away from the base plate being fixedly connected to the movable frame, a shockproof shell fixedly connected to the top of the movable frame, a sliding groove provided at the bottom of the inner wall of the shockproof shell, and a clamping plate slidably connected inside the sliding groove, first threaded rods threadedly connected to both sides of the inside of the shockproof shell, the first threaded rods being rotatably connected to the clamping plates, grooves provided on the front and back of the clamping plates, and a limiting frame slidably connected inside the grooves, a fixing block fixedly connected to the top of the limiting frame, and a second threaded rod rotatably connected inside the fixing block, the second threaded rod being threadedly connected to the clamping plate.

[0006] As a preferred embodiment of this utility model, both sides of the top of the base plate are slidably connected to sliding grooves, and sliders are slidably connected inside the sliding grooves. A connecting rod is hinged to the top of the slider, and the end of the connecting rod away from the slider is hinged to the anti-collision shell. A tension spring is fixedly connected between the two sliders.

[0007] As a preferred embodiment of this utility model, buffers are fixedly connected to both the front and rear sides of the top of the base plate, and the end of the buffer away from the base plate is fixedly connected to the anti-collision shell.

[0008] As a preferred embodiment of this utility model, the front and rear sides of the top of the anti-collision shell are fixedly connected to slide rails, and a cover plate is slidably connected inside the slide rails. Handles are fixedly connected to both sides of the top of the cover plate. The cover plate fits into the anti-collision shell, and bolts are provided on the surface of the cover plate. The bolts are threadedly connected to the anti-collision shell. The surface of the handle is provided with anti-slip textures, and the number of anti-slip textures is several.

[0009] As a preferred embodiment of this utility model, the front and back of the anti-collision shell are provided with openings, the bottom of the inner wall of the anti-collision shell is provided with a placement groove, and a lifting frame is provided inside the placement groove, the lifting frame being slidably connected to the opening.

[0010] As a preferred embodiment of this invention, a protective frame is fixedly connected to the top of the base plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model employs adjustable clamping plates and a limiting frame, allowing the operator to flexibly adjust their positions according to the size of different lithium-ion battery models. Rotating the first threaded rod moves the clamping plates closer together or further apart, achieving clamping and fixing the battery in the width direction; rotating the second threaded rod moves the limiting frame, limiting the battery in the front-to-back length direction, effectively preventing the battery from shaking inside the anti-collision shell. This not only significantly improves the protection effect for batteries of different sizes but also greatly enhances the versatility of the anti-collision shell, effectively solving the problem of limited use of existing anti-collision shells and meeting the needs of various application scenarios. This device has the advantages of ease of use and good protective effect.

[0012] 2. This utility model uses a sliding groove, slider, connecting rod and tension spring. For example, when the anti-collision shell moves down due to vibration, it will drive the connecting rod to move, which in turn will drive the sliders on both sides to move away from each other, thereby stretching the tension spring. According to the relationship between action and reaction forces, the tension spring applies a force to the sliders on both sides to move closer to each other, thereby indirectly applying an upward force to the anti-collision shell, thus buffering the anti-collision shell.

Detailed Implementation

[0015] 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.

[0016] like Figures 1 to 4 As shown, a shockproof shell for lithium-ion batteries includes a base plate 1. A limiting rod 2 is fixedly connected to the top of the base plate 1. Several limiting rods 2 are present. A movable frame 3 is slidably connected to the surface of the limiting rod 2. A spring 4 is fixedly connected to the top of the base plate 1. The end of the spring 4 away from the base plate 1 is fixedly connected to the movable frame 3. A shockproof shell 5 is fixedly connected to the top of the movable frame 3. A groove is provided at the bottom of the inner wall of the shockproof shell 5, and a clamping plate 6 is slidably connected inside the groove. First threaded rods 8 are threadedly connected to both sides of the interior of the shockproof shell 5. The first threaded rods 8 are rotatably connected to the clamping plate 6. Grooves are provided on both the front and back of the clamping plate 6, and a limiting frame 7 is slidably connected inside the grooves. A fixing block 9 is fixedly connected to the top of the limiting frame 7. A second threaded rod 10 is rotatably connected inside the fixing block 9, and the second threaded rod 10 is threadedly connected to the clamping plate 6.

[0017] refer to Figure 2 Both sides of the top of the base plate 1 are slidably connected to sliding grooves, and sliders 11 are slidably connected inside the sliding grooves. A connecting rod 12 is hinged to the top of the slider 11. The end of the connecting rod 12 away from the slider 11 is hinged to the anti-collision shell 5, and a tension spring 13 is fixedly connected between the two sliders 11.

[0018] As a technical optimization of this utility model, by setting up a sliding groove, slider 11, connecting rod 12 and tension spring 13, for example, when the anti-collision shell 5 moves down due to vibration, it will drive the connecting rod 12 to move, thereby causing the sliders 11 on both sides to move away from each other, and then stretching the tension spring 13. According to the relationship between action and reaction forces, the tension spring 13 applies a force to the sliders 11 on both sides to move closer to each other, thereby indirectly applying an upward force to the anti-collision shell 5, thereby buffering the anti-collision shell 5.

[0019] refer to Figure 2 Both the front and rear sides of the top of the base plate 1 are fixedly connected to the buffer 14, and the end of the buffer 14 away from the base plate 1 is fixedly connected to the anti-collision shell 5.

[0020] As a technical optimization of this utility model, by setting the buffer 14, the anti-collision shell 5 can be prevented from moving up and down due to the use of spring 4 and tension spring 13, thereby playing a role in damping and shock absorption. The buffer 14 is a common existing technology and is common knowledge to those skilled in the art, so this application will not describe it in detail.

[0021] refer to Figure 1 The front and rear sides of the top of the anti-collision shell 5 are fixedly connected to slide rails 16. The inside of the slide rails 16 is slidably connected to a cover plate 17. The top two sides of the cover plate 17 are fixedly connected to handles. The cover plate 17 fits into the anti-collision shell 5. The surface of the cover plate 17 is provided with bolts 18, which are threadedly connected to the anti-collision shell 5. The surface of the handle is provided with anti-slip textures, and the number of anti-slip textures is several.

[0022] As a technical optimization of this utility model, by setting up the slide rail 16, cover plate 17 and bolt 18, after the operator puts the lithium battery into the anti-collision shell 5, the operator can slide the cover plate 17 into the slide rail 16 from right to left. Then, the operator can use the bolt 18 to thread the cover plate 17 to the anti-collision shell 5, thereby completing the installation of the cover plate 17. The cover plate 17 can play a role in protecting the top of the lithium battery, thereby improving the protection effect of the lithium battery.

[0023] refer to Figure 2 The front and back of the anti-collision shell 5 are provided with openings 20. The bottom of the inner wall of the anti-collision shell 5 is provided with a placement groove, and a lifting frame 15 is provided inside the placement groove. The lifting frame 15 is slidably connected to the opening 20.

[0024] As a technical optimization of this utility model, by setting up the opening 20, the placement groove and the lifting frame 15, the lifting frame 15 can be placed in the placement groove and can slide up and down in the opening 20. When the operator needs to take out the lithium battery, the operator moves the lifting plate upward, thereby moving the lithium battery upward, so that the operator can easily take out the lithium battery.

[0025] refer to Figure 1 A protective frame 19 is fixedly connected to the top of the base plate 1.

[0026] As a technical optimization of this utility model, the protective frame 19 can protect the movable frame 3 and the spring 4 to a certain extent.

[0027] The working principle and usage process of this utility model are as follows: In use, the operator places the lithium battery into the anti-collision shell 5 from top to bottom. Then, the operator adjusts the distance between the two clamping plates 6 according to the width of the lithium battery. The operator rotates the first threaded rod 8, which in turn moves the first threaded rod 8 and the clamping plates 6 closer together until the lithium battery is clamped. Then, the operator adjusts the distance between the two limiting frames 7 according to the front and rear length of the lithium battery. The operator rotates the second threaded rod 10, which moves the second threaded rod 10 closer to the clamping plate 6. This moves the fixing block 9 and the limiting frame 7 closer to the clamping plate 6 until the limiting frame 7 is in close contact with the front or rear side of the lithium battery. This clamps and positions the lithium battery on the left and right sides and the front and rear sides, preventing the lithium battery from shaking inside the anti-collision shell 5, thereby improving the protection effect of the lithium battery. It can also protect lithium batteries of different sizes. The anti-collision shell 5 and the cover plate 17 form a protective cavity, in which the lithium battery is fixed. This can prevent the lithium battery from being damaged by impact to a certain extent. For example, when the lithium battery moves downward due to vibration, the anti-collision shell 5 and the movable frame 3 move downward, thereby compressing the spring 4. According to the relationship between action and reaction forces, the spring 4 indirectly exerts an upward force on the anti-collision shell 5 and the lithium battery, thereby buffering the lithium battery. The surface of the anti-collision shell 5 can be provided with rubber buffer blocks to improve the buffering effect when impacted. Both the anti-collision shell 5 and the cover plate 17 have openings on their surfaces. These openings can dissipate heat from the lithium battery and also allow the operator to easily observe the status of the lithium battery inside the anti-collision shell 5. The protective frame 19 can prevent the buffer and shock absorption components in the device from being damaged by impact.
