Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to an all-solid-state lithium battery structure. Background Technology

[0002] Solid-state lithium batteries represent the next generation of lithium battery technology, characterized by high specific capacity, long cycle life, and excellent safety performance. Currently, power lithium batteries are widely used in new energy vehicles. In harsh driving environments such as off-road and mountain roads, the chassis of new energy vehicles is prone to impacts, and power batteries are mostly installed in the vehicle chassis.

[0003] A Chinese patent (publication number CN219123363U) discloses a solid-state lithium battery packaging structure. The internal battery structure is protected by the splicing structure of the lower shell and the upper shell. The main support rod, spring and slide rod reduce the impact of vibration caused by external factors on the solid-state lithium battery packaging structure, improve safety and ensure the stability of the solid-state lithium battery packaging structure when dealing with complex working environments.

[0004] However, in the case of the solid-state lithium battery packaging structure designed above, the spring can only be stretched directly by the offset of the hinge point of the support rod through the cooperation of the main support rod and the spring. The impact force is concentrated on the hinge point of the support rod and the spring, which can easily lead to excessive local stress, wear at the hinge point of the support rod, and aggravation of the local stress of the buffer component, thereby reducing the overall buffering efficiency.

[0005] To address these issues, we designed an all-solid-state lithium battery structure. Utility Model Content

[0006] The purpose of this invention is to provide an all-solid-state lithium battery structure to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides an all-solid-state lithium battery structure, which includes a protective shell and a battery body fixedly installed inside the protective shell. A fixing block is fixedly installed on the top of the protective shell, and a round rod is fixedly installed on one side of the fixing block. A slider is slidably sleeved on the outer side of the round rod. The number of sliders is set to two. A telescopic spring is sleeved on the outer side of the round rod. The two ends of the telescopic spring are respectively fixedly connected to the two sliders. A connecting rod is rotatably connected to one side of the slider. A first mounting plate is movably connected to one side of the connecting rod. The battery body is fixedly installed on the top of the first mounting plate.

[0008] Furthermore, a top cover is snapped onto the top of the protective shell, a mounting block is fixedly installed at the bottom of the top cover, a first airbag is fixedly installed in the middle of the mounting block, a first damper is fixedly installed on one side of the bottom of the mounting block, a second mounting plate is fixedly installed on the telescopic end of the first damper, a first damping spring is sleeved on the outside of the first damper, one end of the first damping spring is fixedly connected to the mounting block, the other end of the first damping spring is fixedly connected to the second mounting plate, and a second airbag is fixedly installed on the side of the second mounting plate near the battery body.

[0009] Furthermore, a second damper is fixedly installed on the top of the fixed block, and a first mounting plate is fixedly connected to the telescopic end of the second damper. A second damping spring is sleeved on the outside of the second damper, one end of the second damping spring is fixedly connected to the first mounting plate, and the other end of the second damping spring is fixedly connected to the fixed block.

[0010] Furthermore, a heat dissipation vent is provided on one side of the protective shell, and the number of the heat dissipation vent is set to five, with the five heat dissipation vents being equally spaced on one side of the protective shell.

[0011] Furthermore, a limiting block is fixedly installed on the top of the first mounting plate, and the battery body abuts against the limiting block.

[0012] Furthermore, a guide slider is fixedly installed at the bottom of the slider, and a guide groove is provided on one side of the inner wall of the protective shell, with the guide slider slidably connected to the guide groove.

[0013] Furthermore, a mounting base is fixedly installed on the bottom of the first mounting plate, and the end of the connecting rod away from the slider is movably connected to the mounting base.

[0014] Furthermore, the number of the limiting blocks is set to four, and the four limiting blocks are fixedly installed at the top four corners of the first mounting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. When the first mounting plate moves upward under impact, the connecting rod moves upward synchronously. The two connecting rods drive the two sliders to move away from each other. The telescopic spring is stretched and deformed on the round rod. The second damper and the second damping spring deform synchronously to buffer the impact on the first mounting plate. Affected by the force of the telescopic spring's reset, the two sliders then move closer to each other. When the sliders move, they drive one end of the connecting rod to move closer synchronously, so that the first mounting plate and the battery body are reset inside the protective shell.

[0017] 2. When the battery body is impacted along with the first mounting plate, the top of the battery body comes into contact with the second airbag. The second airbag is compressed, which drives the second mounting plate to move closer to the top cover. The second mounting plate comes into contact with the first airbag. At the same time, the first damper and the first damping spring are also subjected to the compression force of the second mounting plate, generating deformation buffering impact force. The first airbag buffers the second mounting plate simultaneously. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-4This utility model provides a technical solution: It includes a protective shell 1 and a battery body 4 fixedly installed inside the protective shell 1. A fixing block 5 is fixedly installed on the top of the protective shell 1. A round rod 6 is fixedly installed on one side of the fixing block 5. A slider 8 is slidably sleeved on the outer side of the round rod 6. Two sliders 8 are provided. A telescopic spring 7 is sleeved on the outer side of the round rod 6. The two ends of the telescopic spring 7 are respectively fixedly connected to the two sliders 8. A connecting rod 9 is rotatably connected to one side of the slider 8. A first mounting plate 12 is movably connected to one side of the connecting rod 9. The battery body 4 is fixedly installed on the top of the first mounting plate 12. The fixing block 5... A second damper 16 is fixedly installed on the top of the device. A first mounting plate 12 is fixedly connected to the telescopic end of the second damper 16. A second damping spring 17 is sleeved on the outside of the second damper 16. One end of the second damping spring 17 is fixedly connected to the first mounting plate 12, and the other end of the second damping spring 17 is fixedly connected to the fixing block 5. A guide slider 8 is fixedly installed on the bottom of the slider 8. A guide groove is opened on one side of the inner wall of the protective shell 1. The guide slider 8 is slidably connected to the guide groove. A mounting base is fixedly installed on the bottom of the first mounting plate 12. The end of the connecting rod 9 away from the slider 8 is movably connected to the mounting base.

[0025] It should be noted that there are two sliders 8. The two sliders 8 are symmetrically arranged on both sides of the round rod 6 with the vertical axis of the round rod 6 as the center. The first mounting plate 12 is slidably connected to the protective shell 1.

[0026] In practice, when the battery body 4 is placed inside the protective shell 1, and the protective shell 1 and the battery body 4 are subjected to bumps, the protective shell 1 can protect the battery body 4. When the first mounting plate 12 is subjected to a vertical impact and moves upward under force, the first mounting plate 12 drives the connecting rod 9 to move upward. One end of the connecting rod 9 rotates on one side of the slider 8. The two connecting rods 9 respectively drive the two sliders 8 to move away from each other. When the two sliders 8 move away from each other, the telescopic spring 7 is stretched and deformed on the round rod 6. The second damper 16 and the second damping spring 17 deform synchronously to buffer the energy received by the first mounting plate 12. Affected by the reset force of the telescopic spring 7, the two sliders 8 then move closer to each other. When the sliders 8 move, they drive one end of the connecting rod 9 to move closer synchronously, so that the first mounting plate 12 and the battery body 4 are reset inside the protective shell 1.

[0027] See Figure 3The top of the protective shell 1 is snapped with a top cover 2. The bottom of the top cover 2 is fixedly installed with a mounting block 14. The middle of the mounting block 14 is fixedly installed with a first airbag 15. The bottom side of the mounting block 14 is fixedly installed with a first damper 10. The telescopic end of the first damper 10 is fixedly installed with a second mounting plate 18. The outside of the first damper 10 is sleeved with a first damping spring 11. One end of the first damping spring 11 is fixedly connected to the mounting block 14. The other end of the first damping spring 11 is fixedly connected to the second mounting plate 18. The second mounting plate 18 is fixedly installed with a second airbag 19 on the side near the battery body 4.

[0028] It should be noted that the mounting block 14 has a mounting groove in the middle, and the first airbag 15 is fixedly installed inside the mounting groove of the mounting block 14.

[0029] By setting the first airbag 15 and the second airbag 19, when the battery body 4 moves with the first mounting plate 12, the top of the battery body 4 first comes into contact with the second airbag 19. The second airbag 19 is squeezed, which drives the second mounting plate 18 to move closer to the top cover 2. The second mounting plate 18 gradually comes into contact with the first airbag 15. At the same time, the first damper 10 and the first damping spring 11 are also squeezed by the second mounting plate 18 and move closer to the mounting block 14. The first damper 10 and the first damping spring 11 deform to buffer the impact force on the second mounting plate 18. The first airbag 15 simultaneously buffers the second mounting plate 18.

[0030] See Figure 1 The protective shell 1 has a heat dissipation vent 3 on one side, and there are five heat dissipation vents 3, which are equally spaced on one side of the protective shell 1.

[0031] By opening multiple heat dissipation vents 3, the protective shell 1 is cooled, which helps to improve the stability of the battery body 4.

[0032] See Figure 2 A limiting block 13 is fixedly installed on the top of the first mounting plate 12. The battery body 4 abuts against the limiting block 13. There are four limiting blocks 13. The four limiting blocks 13 are fixedly installed at the four corners of the top of the first mounting plate 12.

[0033] The battery body 4 is clamped and fixed by setting four limiting blocks 13. When the battery body 4 is placed on the top of the first mounting plate 12, the limiting blocks 13 fit with the corners of the battery body 4 to limit the battery body 4 and fix the battery body 4.

[0034] Working principle: When the device is in use, after the battery body 4 is placed inside the protective shell 1, when the protective shell 1 and the battery body 4 are bumped, the protective shell 1 can protect the battery body 4. When the first mounting plate 12 is subjected to vertical impact, the first mounting plate 12 moves upward under force, and the first mounting plate 12 drives the connecting rod 9 to move upward. One end of the connecting rod 9 rotates on one side of the slider 8. The two connecting rods 9 respectively drive the two sliders 8 to move away from each other. When the two sliders 8 move away from each other, the telescopic spring 7 is stretched on the round rod 6 and deforms. The second damper 16 and the second damping spring 17 deform synchronously to buffer the energy received by the first mounting plate 12. Affected by the reset force of the telescopic spring 7, the two sliders 8 then move closer to each other. When the sliders 8 move, they drive one end of the connecting rod 9 to move closer synchronously, so that the first mounting plate 12 and the battery body 4 are reset inside the protective shell 1.

[0035] When the battery body 4 moves with the first mounting plate 12, the top of the battery body 4 first comes into contact with the second airbag 19. The second airbag 19 is compressed, which drives the second mounting plate 18 to move closer to the top cover 2. The second mounting plate 18 gradually comes into contact with the first airbag 15. At the same time, the first damper 10 and the first damping spring 11 are also compressed by the second mounting plate 18 and move closer to the mounting block 14. The first damper 10 and the first damping spring 11 deform to buffer the impact force on the second mounting plate 18. The first airbag 15 simultaneously buffers the second mounting plate 18.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
