Description

Technical Field

[0001] This utility model belongs to the field of lithium battery technology, and in particular relates to a fast-charging lithium battery with heat dissipation and explosion-proof function. Background Technology

[0002] Lithium batteries are rechargeable batteries that use lithium metal or lithium compounds as the main chemical components. Due to their high energy density, long lifespan, and lightweight characteristics, lithium batteries have been widely used in consumer electronics, transportation, energy storage, and military fields.

[0003] When a lithium battery is charging, a certain resistance is generated inside the battery due to the flow of current. When the current passes through the internal resistance of the battery, some energy is converted into heat. If the battery is not secured during this process, it may explode when subjected to external impact. Therefore, we propose a fast-charging lithium battery with heat dissipation and explosion-proof function. Utility Model Content

[0004] The purpose of this utility model is to provide a fast-charging lithium battery with heat dissipation and explosion-proof function. Through the reaction force of the second spring, the protective plate will be squeezed, which in turn squeezes the clamping block, thereby making the clamping block clamp the card block, solving the problem that the battery may explode if it is not fixed and is subjected to external impact during charging.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a fast-charging lithium battery with heat dissipation and explosion-proof function, including a lithium battery shell, a cover snapped onto the top of the lithium battery shell, an explosion-proof heat dissipation mechanism provided inside the lithium battery shell, and an alarm mechanism provided at the bottom of the cover;

[0007] The explosion-proof heat dissipation mechanism includes a slide groove inside the lithium battery casing. A slider is slidably connected to the inner wall of the slide groove. A telescopic rod is fixedly connected to the outer wall of the slider. A spring is fixedly connected to the side of the slider near the telescopic rod. A connecting rod is rotatably connected to the outer wall of the slider. A protective plate is rotatably connected to the end of the connecting rod away from the slider. A second slide groove is opened inside the lithium battery casing. A damper is fixedly connected to the outer wall of the protective plate. A second spring is fixedly connected to the outer wall of the protective plate. A mounting block is fixedly connected to the inner wall of the lithium battery casing. A lithium battery is inserted into the inner wall of the mounting block. A locking block is fixedly connected to the outer wall of the lithium battery.

[0008] Furthermore, a clamping block is fixedly connected to the outer wall of the protective plate, a heat dissipation plate is snapped into the inner wall of the lithium battery casing, four slide grooves are provided in total, and the side of the telescopic rod away from the slider is fixedly connected to the inner wall of the slide groove.

[0009] Furthermore, the end of the spring away from the slider is fixedly connected to the inner wall of the slide groove, the telescopic rod is located inside the spring, and the inner wall of the slide groove is slidably connected to the outer wall of the protective plate.

[0010] Furthermore, the side of the damper away from the protective plate is fixedly connected to the inner wall of the lithium battery casing, the end of the second spring away from the protective plate is fixedly connected to the inner wall of the lithium battery casing, the damper is located inside the second spring, the inner wall of the clamping block is engaged with the outer wall of the card block, and a total of four heat dissipation plates are provided.

[0011] Furthermore, the alarm mechanism includes two telescopic rods fixedly connected to the outer wall of the cover.

[0012] Furthermore, a fixing plate is fixedly connected to the side of the telescopic rod two away from the cover, and a spring three is fixedly connected to the side of the fixing plate close to the telescopic rod two.

[0013] Furthermore, the end of the spring away from the fixing plate is fixedly connected to the outer wall of the cover, and a fixing shaft is fixedly connected to the outer wall of the fixing plate.

[0014] Furthermore, a limiting frame is fixedly connected to the outer wall of the cover, the inner wall of the limiting frame is slidably connected to the outer wall of the fixed shaft, an alarm is fixedly connected to the outer wall of the cover, the alarm is located inside the limiting frame, and a controller is fixedly connected to the inner wall of the lithium battery casing.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a protective plate. First, the cover is manually removed, and then the protective plate is moved to both sides. While moving the protective plate, the damper and spring are compressed, and the connecting rod is also moved. As the connecting rod moves, the slider slides in the groove. While the slider slides, it compresses the spring and telescopic rod. This mechanism can reduce the impact force when the lithium battery explodes, and at the same time, it firmly fixes the lithium battery in the lithium battery casing, preventing damage to internal parts from external impacts during use.

[0017] 2. This utility model features a fixed shaft that secures the cover to the lithium battery casing. Once the cover is in place, the fixed plate contacts the top of the lithium battery. If the lithium battery bulges during charging, the fixed plate will be lifted, compressing the telescopic rod and spring, which in turn moves the fixed shaft upwards. When the fixed shaft contacts the alarm, it triggers a battery bulge warning, preventing further bulging and reducing the risk of subsequent explosion. This mechanism can trigger the alarm when the battery bulges and then immediately cut off the battery charging power via the controller, further reducing the risk of explosion due to battery bulging.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5As shown, this utility model is a fast-charging lithium battery with heat dissipation and explosion-proof function, including a lithium battery shell 101, a cover 102 snapped onto the top of the lithium battery shell 101, an explosion-proof heat dissipation mechanism 2 provided inside the lithium battery shell 101, and an alarm mechanism 3 provided at the bottom of the cover 102.

[0029] The explosion-proof heat dissipation mechanism 2 includes a groove 201 formed inside the lithium battery casing 101. A slider 202 is slidably connected to the inner wall of the groove 201, and a telescopic rod 203 is fixedly connected to the outer wall of the slider 202. The lithium battery casing 101, made of aluminum alloy, is lightweight, which helps reduce the overall weight of the battery. It also has high thermal conductivity, which helps the battery dissipate heat quickly during operation. A spring 204 is fixedly connected to the side of the slider 202 near the telescopic rod 203. A connecting rod 205 is rotatably connected to the outer wall of the lithium battery casing 101. A protective plate 206 is rotatably connected to the end of the connecting rod 205 away from the slider 202. A second sliding groove 207 is provided inside the lithium battery casing 101. A spring 204 is installed; when the slider 202 slides within the groove 201, it compresses the spring 204, and the reaction force of the spring 204 buffers the slider 202. A damper 208 is fixedly connected to the outer wall of the protective plate 206, and a second spring 209 is also fixedly connected to the outer wall of the protective plate 206. (The lithium battery...) A mounting block 211 is fixedly connected to the inner wall of the outer casing 101. A lithium battery 212 is inserted into the inner wall of the mounting block 211. A protective plate 206 is provided, which is made of aluminum foam. The protective plate 206 has a good energy absorption capacity and can effectively disperse the impact force in the event of an explosion or impact. Moreover, the low density of the metal foam will not excessively increase the weight of the battery. A locking block 213 is fixedly connected to the outer wall of the lithium battery 212, and a clamping block 210 is fixedly connected to the outer wall of the protective plate 206. A heat dissipation plate 2 is clamped to the inner wall of the lithium battery casing 101. 14. There are four slides 201. The heat dissipation plate 214 is set to dissipate the heat released by the battery during charging, so as to prevent the battery from overheating and exploding. The side of the telescopic rod 203 away from the slider 202 is fixedly connected to the inner wall of the slide 201. The end of the spring 204 away from the slider 202 is fixedly connected to the inner wall of the slide 201. The telescopic rod 203 is located inside the spring 204. The inner wall of the second slide 207 is slidably connected to the outer wall of the protective plate 206.

[0030] The damper 208 is fixedly connected to the inner wall of the lithium battery casing 101 on the side away from the protective plate 206. The spring 209 is fixedly connected to the inner wall of the lithium battery casing 101 on the end away from the protective plate 206. The damper 208 is located inside the spring 209. The inner wall of the clamping block 210 is engaged with the outer wall of the locking block 213. By setting the clamping block 210, when the lithium battery 212 is subjected to external force, the clamping block 210 clamps the locking block 213, so the lithium battery 212 will not shake inside the lithium battery casing 101. The heat sink 2... There are four alarm mechanisms 14 in total. The alarm mechanism 3 includes two telescopic rods 301 that are fixedly connected to the outer wall of the cover 102. There are two telescopic rods 301. A fixing plate 303 is fixedly connected to the side of the telescopic rod 301 away from the cover 102. By setting the fixing plate 303, since the battery bulge is generally located at the top of the battery, when the battery starts to bulge, it will squeeze the fixing plate 303, causing the fixing shaft 304 to rise. A spring 302 is fixedly connected to the side of the fixing plate 303 near the telescopic rod 301.

[0031] The end of spring 302 away from the fixing plate 303 is fixedly connected to the outer wall of the cover 102. The fixing plate 303 is fixedly connected to the outer wall of the fixing shaft 304. The outer wall of the cover 102 is fixedly connected to the limiting frame 305. The inner wall of the limiting frame 305 is slidably connected to the outer wall of the fixing shaft 304. By setting the limiting frame 305, since the battery bulging may have an irregular shape, the limiting frame 305 limits the fixing shaft 304, so that the fixing shaft 304 can smoothly contact the alarm 306. The alarm 306 is fixedly connected to the outer wall of the cover 102. The alarm 306 is located inside the limiting frame 305. The inner wall of the lithium battery casing 101 is fixedly connected to the controller 307. By setting the controller 307, when the alarm 306 is triggered, the controller 307 can urgently cut off the power supply of the lithium battery 212, prevent the lithium battery 212 from continuing to bulge, and reduce the risk of subsequent lithium battery 212 explosion.

[0032] One specific application of this embodiment is:

[0033] First, manually remove the cover 102. Then, move the protective plates 206 to both sides. Moving the protective plates 206 will compress the damper 208 and spring 209, and will also move the connecting rod 205. As the connecting rod 205 moves, it will cause the slider 202 to slide within the groove 201. While sliding, the slider 202 will compress the spring 204 and the telescopic rod 203. As the protective plates 206 move relative to each other, the clamping blocks 210 will also move away from each other. When the clamping blocks 210 are far apart, manually insert the lithium battery 212 into the mounting block 211, and then release the protective plate 206. Due to the reaction force of springs 209 and 204, the protective plate 206 will be squeezed, which in turn will squeeze the clamping block 210, thereby clamping the locking block 213. During charging, the heat dissipation plate 214 provides ventilation to dissipate heat from the lithium battery 212. And when the lithium battery 212 explodes, springs 204 and 209 will release the pressure. The reaction force generated by the second 209 buffers the impact force during the explosion. This mechanism can reduce the impact force when the lithium battery 212 explodes, and at the same time firmly fix the lithium battery 212 in the lithium battery casing 101 to prevent damage to internal parts caused by external impacts during use. Then, the cover 102 is clipped onto the lithium battery casing 101. After the cover 102 is clipped, the fixing plate 303 will contact the top of the lithium battery 212. If the lithium battery 212 bulges during charging, it will push up the fixing plate 303, thereby squeezing the telescopic rod 301 and the spring 302, and then driving the fixing shaft 304 to move upward. When the fixing shaft 304 contacts the alarm 306, it triggers the battery bulging warning, prevents the battery from bulging further, and reduces the risk of subsequent explosion. This mechanism can trigger the alarm 306 when the battery bulges, and then cut off the battery charging power supply in an emergency through the controller 307 to reduce the risk of subsequent explosion due to battery bulging.
