Description

Technical Field

[0001] This utility model relates to the field of solid-state sodium-ion battery technology, and in particular to a puncture-resistant solid-state sodium-ion battery module structure. Background Technology

[0002] Solid-state sodium-ion batteries are a new type of rechargeable battery technology that uses the migration of sodium ions (Na⁺) in a solid electrolyte to achieve charging and discharging. They combine the advantages of abundant sodium resources and low cost with the high safety and high energy density of solid electrolytes, and are considered a strong contender for the next generation of energy storage technology.

[0003] However, existing technologies have some problems: existing solid sodium-ion batteries usually only have a protective film on the surface. However, the battery may be punctured by sharp objects during use, causing electrolyte leakage, which may react with oxygen and moisture in the air and cause violent combustion or explosion. Therefore, we propose a puncture-resistant solid sodium-ion battery module structure. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a puncture-resistant solid sodium-ion battery module structure. By using puncture-resistant plates, buffer components, and arc plates to block and buffer puncture objects, the structure can prevent puncture objects from entering the battery and causing damage.

[0005] This utility model is implemented as follows: a puncture-resistant solid sodium-ion battery module structure includes a shell, a battery body disposed inside the shell, a top cover detachably connected to one side of the shell, a fixing component disposed on the shell for fixing the top cover, a buffer plate fixedly connected to the shell, an anti-puncture plate fixedly connected to the buffer plate, a guide plate movably connected to the buffer plate, a buffer component disposed between the guide plate and the buffer plate, arc-shaped plates fixedly connected to both sides of the guide plate, and a limit plate fixedly connected to the buffer plate.

[0006] Optionally, the fixing component includes a fixing block, and the housing has a fixing groove, in which the fixing block is engaged.

[0007] Optionally, the inner wall of the outer casing fixing groove is provided with a slide rail, the inner wall of the slide rail is slidably connected with a fixing pin, the fixing block is provided with a slot, the fixing pin is engaged in the slot, a fixing spring is fixedly connected to the fixing pin, the fixing spring is fixedly connected to the inner wall of the slide rail, and a pull ring is fixedly connected to one end of the fixing pin.

[0008] Optionally, the anti-penetration plate has multiple sets of honeycomb holes, which are evenly distributed on the anti-penetration plate, and the inner walls of the honeycomb holes are inclined.

[0009] Optionally, the buffer assembly includes a guide rod, which is fixedly connected to a guide plate. A guide seat is fixedly connected to the buffer plate, and a groove is provided on the guide seat. The guide rod is slidably connected in the groove.

[0010] Optionally, the buffer assembly further includes a buffer spring, one end of which is fixedly connected to the guide rod, and the other end of which is fixedly connected to the inner wall of the guide seat's groove.

[0011] Optionally, the guide plate corresponds to the honeycomb holes on the anti-penetration plate, and an anti-slip strip is fixedly connected to the arc-shaped plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model is equipped with an anti-penetration plate. When a sharp object (such as a nail or fragment) impacts the material at a vertical or near-vertical angle, the stress will be concentrated around the puncture point, causing local material failure (such as cracking or tearing). The inclined honeycomb channels will force the sharp object to slide along the channel direction, decomposing the vertical impact force into shear force along the channel direction and normal force perpendicular to the channel direction, thereby significantly reducing the positive penetration kinetic energy of the puncture object and thus preventing the battery from being punctured and damaged by the puncture object.

[0014] 2. This utility model is equipped with a buffer component. When the puncture object passes through the honeycomb holes, it will impact the guide plate. After the guide plate is impacted, it will drive the guide rod to compress the buffer spring and slide in the groove of the guide seat. The buffer spring will generate elastic deformation, converting the impact force of the puncture object into elastic potential energy, thereby further reducing the penetration ability of the puncture object and protecting the internal battery.

[0015] 3. The upper end of the guide plate of this utility model is semi-circular. After being buffered by the buffer component, the puncture object will slide from the guide plate to the arc plate. The arc surface guides the puncture object to deflect, which plays a certain buffering role. Then the puncture object slides along the arc plate. The anti-slip strip on the arc plate further slows down the speed of the puncture object. Finally, a limit plate is set to support the arc plate, improve its puncture resistance, and block the puncture object, further protecting the battery and preventing the battery from being penetrated and damaged.

[0024] 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.

[0025] like Figures 1 to 6 As shown in the figure, the embodiment of this utility model provides a puncture-resistant solid sodium-ion battery module structure, including a shell 1. The shell 1 is made of aluminum alloy. The main function of the shell 1 is to support the entire device and ensure the stability of the device.

[0026] Furthermore, a battery body 2 is provided inside the outer casing 1, and a top cover 3 is detachably connected to one side of the outer casing 1. A fixing component 4 is provided on the outer casing 1 to fix the top cover 3, and positive and negative terminals are provided on the top cover 3.

[0027] Specifically, the fixing component 4 includes a fixing block 41, and a fixing groove is provided on the outer shell 1, in which the fixing block 41 is snapped into the fixing groove.

[0028] Furthermore, a slide is provided on the inner wall of the fixing groove of the outer shell 1, and a fixing pin 42 is slidably connected to the inner wall of the slide. A slot is provided on the fixing block 41, and the fixing pin 42 is engaged in the slot. A fixing spring 43 is fixedly connected to the fixing pin 42, and the fixing spring 43 is fixedly connected to the inner wall of the slide. A pull ring 44 is fixedly connected to one end of the fixing pin 42.

[0029] Specifically, by aligning the fixing block 41 on the top cover 3 with the fixing groove of the outer casing 1, the top cover 3 is pressed down, causing the fixing block 41 to be inserted into the fixing groove. During the insertion of the fixing block 41, the fixing block 41 pushes the fixing pin 42 to compress the fixing spring 43 and move it into the slide until the slot on the fixing block 41 corresponds to the fixing pin 42. At this time, the fixing pin 42 will automatically engage in the slot of the fixing block 41 due to the fixing spring 43 and the rebound force, thus fixing the top cover 3. When it is necessary to remove the top cover 3, the fixing pin 42 is pulled by pulling the pull ring 44 to compress the fixing spring 43 and move into the slide. At this time, the fixing pin 42 no longer engages with the fixing block 41, and the top cover 3 can be removed. The top cover 3 can be quickly installed and removed by the fixing component 4, which facilitates the maintenance and replacement of the battery body 2.

[0030] Furthermore, a buffer plate 5 is fixedly connected to the outer shell 1, and an anti-penetration plate 6 is fixedly connected to the buffer plate 5. Multiple sets of honeycomb holes are opened inside the anti-penetration plate 6, and the multiple sets of honeycomb holes are evenly distributed on the anti-penetration plate 6. The inner wall of the honeycomb holes is inclined.

[0031] Specifically, when a sharp object (such as a nail or fragment) impacts a material at a vertical or near-vertical angle, stress is concentrated around the puncture point, causing local material failure (such as cracking or tearing). The inclined honeycomb channels force the sharp object to slide along the channel direction, decomposing the vertical impact force into shear force along the channel direction and normal force perpendicular to the channel direction, thereby significantly reducing the positive penetration kinetic energy of the puncture object and thus preventing the battery from being punctured and damaged.

[0032] Furthermore, a guide plate 7 is movably connected to the buffer plate 5, and a buffer assembly 8 is provided between the guide plate 7 and the buffer plate 5. The buffer assembly 8 includes a guide rod 81, which is fixedly connected to the guide plate 7. A guide seat 82 is fixedly connected to the buffer plate 5, and a groove is provided on the guide seat 82. The guide rod 81 is slidably connected in the groove.

[0033] Furthermore, the buffer assembly 8 also includes a buffer spring 83, one end of which is fixedly connected to the guide rod 81, and the other end of which is fixedly connected to the inner wall of the groove of the guide seat 82.

[0034] Specifically, when the puncture object passes through the honeycomb holes, it will impact the guide plate 7. After the guide plate 7 is impacted, it will drive the guide rod 81 to compress the buffer spring 83 and slide it in the groove of the guide seat 82. The buffer spring 83 will undergo elastic deformation, converting the impact force of the puncture object into elastic potential energy, thereby further reducing the penetration ability of the puncture object and protecting the internal battery.

[0035] Furthermore, curved plates 9 are fixedly connected to both sides of the guide plate 7, and limit plates 10 are fixedly connected to the buffer plate 5. The honeycomb holes on the guide plate 7 correspond to those on the anti-penetration plate 6, and anti-slip strips 11 are fixedly connected to the curved plates 9.

[0036] Specifically, the upper end of the guide plate 7 is semi-circular. After being buffered by the buffer assembly 8, the puncture object slides from the guide plate 7 onto the arc plate 9. The arc surface guides the puncture object to deflect, which plays a certain buffering role. Then, the puncture object slides along the arc plate 9. The anti-slip strip 11 on the arc plate 9 further slows down the speed of the puncture object. Finally, a limit plate 10 is set to support the arc plate 9, improve its puncture resistance, and block the puncture object, further protecting the battery and preventing the battery from being penetrated and damaged.

[0037] The working principle of this utility model is as follows:

[0038] This utility model is equipped with a puncture-proof plate 6. When a sharp object (such as a nail or fragment) impacts the material at a vertical or near-vertical angle, the stress will be concentrated around the puncture point, causing local material failure (such as cracking or tearing). The inclined honeycomb channels will force the sharp object to slide along the channel direction, decomposing the vertical impact force into a shear force along the channel direction and a normal force perpendicular to the channel direction, thereby significantly reducing the positive penetration kinetic energy of the puncture object and thus preventing the battery from being punctured and damaged by the puncture object.

[0039] This utility model is equipped with a buffer component 8. When the puncture object passes through the honeycomb holes, it will impact the guide plate 7. After the guide plate 7 is impacted, it will drive the guide rod 81 to compress the buffer spring 83 and slide it in the groove of the guide seat 82. The buffer spring 83 will generate elastic deformation, converting the impact force of the puncture object into elastic potential energy, thereby further reducing the penetration ability of the puncture object and protecting the internal battery.

[0040] The upper end of the guide plate 7 of this utility model is semi-circular. After being buffered by the buffer component 8, the puncture object slides from the guide plate 7 onto the arc plate 9. The arc surface guides the puncture object to deflect, which plays a certain buffering role. Then the puncture object slides along the arc plate 9. The anti-slip strip 11 on the arc plate 9 further slows down the speed of the puncture object. Finally, a limit plate 10 is set to support the arc plate 9, improve its puncture resistance, and block the puncture object, further protecting the battery and preventing the battery from being penetrated and damaged.

[0041] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
