Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to a battery structure with an explosion-proof and long-life lithium battery pack casing. Background Technology

[0002] Lithium-ion batteries are a new type of high-energy battery developed in the 20th century. The negative electrode of this battery is metallic lithium, while the positive electrode uses materials such as MnO2, SOCl2, and (CFx)n. They entered practical application in the 1970s. Due to their advantages such as high energy density, high battery voltage, wide operating temperature range, and long storage life, they have been widely used in military and civilian small electronic devices, such as mobile phones, portable computers, camcorders, and cameras, partially replacing traditional batteries. High-capacity lithium batteries have been tested in electric vehicles and will become one of the main power sources for electric vehicles in the 21st century. They will also be used in artificial satellites, aerospace, and energy storage.

[0003] Because lithium-ion batteries have a certain internal resistance, they generate heat while outputting electrical energy to power pure electric vehicles, causing their own temperature to rise. If the battery's heat dissipation is not good, the high-temperature battery may catch fire and cause an explosion. Utility Model Content

[0004] The purpose of this invention is to provide a battery structure with an explosion-proof and long-life lithium battery pack casing, which solves the problem mentioned in the background art that the battery itself has poor heat dissipation, which may cause the high-temperature battery to catch fire and generate explosion factors.

[0005] This application provides a battery structure with an explosion-proof and long-life lithium battery pack casing, including a battery pack, a mounting plate fixedly connected to the bottom of the battery pack, a connecting plate movably connected to the bottom of the mounting plate, a wind guide plate fixedly connected to the lower section of the connecting plate, a plurality of inclined wind guide grooves formed on the wind guide plate, and a heat-conducting layer provided at the lower end of the battery pack.

[0006] By adopting the above technical solution, during vehicle operation, the heat generated by the battery pack is dissipated through the heat-conducting layer. The vehicle's speed generates wind speed, and the inclined air guide groove on the air guide plate directs the airflow into the lower end of the battery pack. The wind blows across the lower end of the battery pack, dissipating the heat from the heat-conducting layer. When the air guide plate is bumped, it needs to be replaced. The worker pushes the limiting rod upward, causing it to move upward. The limiting rod then moves the limiting block upward. The limiting rod, through the fixed plate, compresses the spring again, causing the limiting block to disconnect from the mounting plate. The worker then rotates the limiting rod, causing the fixed plate to rotate. The fixed plate rotates the spring, and the other end of the spring rotates through the rotating disc. The rotating disc rotates through the rotating ring, causing the limiting rod to rotate until the limiting block aligns with the second limiting port. The compressed spring then pops out, moving the limiting rod and the limiting block out of the second limiting port, allowing the worker to replace the air guide plate.

[0007] Optionally, the thermal conductive layer is made of thermally conductive pad material, and the thermally conductive pad has a thickness of 2 mm.

[0008] By adopting the above technical solution, the heat generated by the battery can be quickly dissipated.

[0009] Optionally, the connecting plate is provided with a limiting component, the limiting component including a spring, one end of the spring is fixedly connected to a fixed disk, the other end of the spring is fixedly connected to a rotating disk, a limiting rod is fixedly connected to the inner ring of the fixed disk, a rotating ring is rotatably connected to the outer wall of the rotating disk, a limiting sleeve is fixedly connected to the outer wall of the rotating ring, and a limiting block is fixedly connected to the limiting rod.

[0010] By adopting the above technical solution, the limiting component facilitates users to quickly replace the air guide plate.

[0011] Optionally, the rotating ring is slidably connected to the limiting rod.

[0012] By adopting the above technical solution, the movement of the limit rod is guaranteed.

[0013] Optionally, the pulling end of the limiting rod is provided with a pulling disc, and the surface of the pulling disc is provided with an anti-slip layer.

[0014] By adopting the above technical solution, the pull plate makes it easy for users to push and pull.

[0015] Optionally, the mounting plate may have multiple sets of second limiting ports.

[0016] By adopting the above technical solution, the connection between the connecting plate and the mounting plate is ensured through the second limiting port.

[0017] Optionally, the connecting plate has multiple sets of first limiting ports.

[0018] By adopting the above technical solution, the connection between the connecting plate and the mounting plate is ensured through the first limiting port.

[0019] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0020] The technical solution of this application utilizes the heat generated by the battery pack during the operation of the car to be discharged through the heat-conducting layer. The speed of the car's movement generates wind speed, and the inclined air guide channel on the air guide plate directs the wind into the lower end of the battery pack. The wind blows the lower end of the battery pack, dissipating the heat from the heat-conducting layer and quickly cooling the battery inside the battery pack, thus preventing the battery from catching fire and exploding due to high temperature.

[0021] When the air guide plate is bumped, it needs to be replaced. The worker pushes the limit rod upwards, causing it to move upwards. This causes the limit block to move upwards as well. The limit rod then compresses the spring again via the fixed plate, disengaging the limit block from the mounting plate. The worker then rotates the limit rod, causing the fixed plate to rotate, which in turn rotates the spring. The other end of the spring rotates via the rotating disc, which in turn rotates via the rotating ring. The limit rod causes the limit block to rotate to align with the second limiting port, at which point the compressed spring pops out, moving the limit rod and limit block out of the second limiting port. The worker can then replace the air guide plate quickly, improving work efficiency. Attached Figure Description

Detailed Implementation

[0030] Please see Figure 1-6 This utility model provides a technical solution: a battery structure with an explosion-proof and long-life lithium battery pack shell, including a battery pack 1, a mounting plate 2 fixedly connected to the bottom of the battery pack 1, a connecting plate 3 movably connected to the bottom of the mounting plate 2, a wind guide plate 9 fixedly connected to the lower section of the connecting plate 3, multiple sets of inclined wind guide grooves 5 opened on the wind guide plate 9, and a heat-conducting layer 8 provided at the lower end of the battery pack 1.

[0031] In the above technical solution, during vehicle operation, the heat generated by the battery pack 1 is dissipated through the heat-conducting layer 8. The vehicle's speed generates wind speed, and the inclined air guide groove 5 on the air guide plate 9 directs the airflow into the lower end of the battery pack 1. The wind blows across the lower end of the battery pack 1, dissipating the heat from the heat-conducting layer 8. When the air guide plate 9 is bumped, it needs to be replaced. The operator pushes the limiting rod 402 upward, causing it to move upward. The limiting rod 402 drives the limiting block 407 upward, and the limiting rod 402 compresses the spring 404 again through the fixing plate 403. This disconnects the limiting block 407 from the mounting plate 2. Then, the operator rotates the limiting rod 402, which in turn rotates the fixed plate 403. The fixed plate 403 then rotates the spring 404. The other end of the spring 404 rotates via the rotating plate 405, which in turn rotates via the rotating ring 406. The limiting rod 402 causes the limiting block 407 to rotate to coincide with the second limiting port 7. Then, the spring 404 is compressed and pops out. The spring 404 moves the limiting rod 402 and the limiting block 407 out of the second limiting port 7, and the operator replaces the air guide plate 9.

[0032] In the technical solution of this utility model, such as Figure 3 As shown, the thermal conductive layer 8 is made of thermal pad material with a thickness of 2 mm, which quickly dissipates the heat generated by the battery.

[0033] In the technical solution of this utility model, such as Figure 1 and Figure 4 and Figure 5 As shown, a limiting component 4 is provided on the connecting plate 3. The limiting component 4 includes a spring 404. One end of the spring 404 is fixedly connected to a fixed disk 403, and the other end of the spring 404 is fixedly connected to a rotating disk 405. A limiting rod 402 is fixedly connected to the inner ring of the fixed disk 403. A rotating ring 406 is rotatably connected to the outer wall of the rotating disk 405. A limiting sleeve 401 is fixedly connected to the outer wall of the rotating ring 406. A limiting block 407 is fixedly connected to the limiting rod 402. The limiting component 4 facilitates the user to quickly replace the air guide plate 9.

[0034] In the technical solution of this utility model, such as Figure 4 and Figure 5 As shown, the rotating ring 406 is slidably connected to the limiting rod 402 to ensure that the limiting rod 402 can move.

[0035] In the technical solution of this utility model, such as Figure 4 As shown, the pull end of the limit rod 402 is equipped with a pull plate, and the surface of the pull plate is provided with an anti-slip layer, so that the user can push and pull it through the pull plate.

[0036] In the technical solution of this utility model, such as Figure 3 As shown, the mounting plate 2 has multiple sets of second limiting ports 7, which ensure the connection between the connecting plate 3 and the mounting plate 2.

[0037] In the technical solution of this utility model, such as Figure 2 As shown, the connecting plate 3 has multiple sets of first limiting ports 6, which ensure the connection between the connecting plate 3 and the mounting plate 2.

[0038] During use, as the car is in motion, the heat generated by the battery pack 1 is dissipated through the heat-conducting layer 8. The car's speed generates wind, and the inclined air guide trough 5 on the air guide plate 9 directs the airflow into the lower end of the battery pack 1. The wind blows across the lower end of the battery pack 1, dissipating the heat from the heat-conducting layer 8. When the air guide plate 9 is bumped, it needs to be replaced. The operator pushes the limiting rod 402 upwards, causing it to move upwards. The limiting rod 402 then moves the limiting block 407 upwards. The limiting rod 402, through the fixing plate 403, further compresses the spring 404, thus limiting the movement. Block 407 is disconnected from mounting plate 2. Then, the operator rotates the limiting rod 402, which in turn rotates the fixed plate 403. The fixed plate 403 then rotates the spring 404. The other end of the spring 404 rotates via the rotating plate 405, which in turn rotates via the rotating ring 406. The limiting rod 402 rotates the limiting block 407 90 degrees so that it coincides with the second limiting port 7. Then, the spring 404 is compressed and pops out. The spring 404 moves the limiting rod 402 and the limiting block 407 out of the second limiting port 7, and the operator replaces the air guide plate 9.
