Description

Technical Field

[0001] This utility model relates to the field of battery cell technology, and in particular to a battery cell anti-collision protection device. Background Technology

[0002] Battery cells are the core unit of a battery pack, often referred to as the heart of the battery, and their performance directly determines the energy, lifespan, and safety of the entire battery system. They are mainly classified into three categories based on their shape: cylindrical, prismatic, and pouch cells, each with different characteristics in energy density, manufacturing cost, and structural strength. Essentially, a battery cell is an independent, closed system that converts chemical energy into electrical energy. Its core materials and structure include positive and negative electrodes, a separator, and an electrolyte. Charging and discharging are achieved through the insertion and extraction of lithium ions between the positive and negative electrodes.

[0003] Currently, protective devices are generally required in the practical application of battery cells to ensure their safety. However, most existing protective devices rely solely on a single outer casing for physical isolation. Such structures typically lack dedicated impact-absorbing mechanisms. Since the casing itself usually lacks sufficient impact resistance and energy absorption capacity, when the device collides with an external object, the impact energy directly acts on the casing, causing deformation or even breakage. This deformation further propagates inward, causing physical damage such as compression or puncture to the internal battery cells, severely affecting the structural integrity and electrical safety of the cells, thus reducing overall protective performance. Therefore, relying solely on passive protection from the casing is insufficient to meet the safety requirements for impact resistance, collision protection, and cushioning in practical applications. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a battery cell anti-collision protection device that has anti-collision function, prevents deformation of the casing, effectively protects the battery cells inside the casing, improves protection performance, and thus solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a battery cell anti-collision protection device, comprising a housing, wherein a battery cell body is fixedly installed at the middle position of the upper surface of the bottom end of the housing, a telescopic rod is provided through the outer surface of the housing, and one end of the telescopic rod is fixedly connected to an anti-collision plate on the outer side of the housing, and the other end of the telescopic rod is fixedly connected to a protective pad on the inside of the housing, and a spring is sleeved on the outer surface of the telescopic rod between the anti-collision plate and the housing.

[0006] Preferably, a reinforcing block is fixedly connected inside the shell. There are multiple reinforcing blocks, which are evenly distributed at the four corners inside the shell. The reinforcing blocks are matched with the shell.

[0007] Preferably, the telescopic rod is movably connected to the housing.

[0008] Preferably, the housing is provided with a top cover, which is threadedly connected to a threaded hole on the top surface of the housing by bolts.

[0009] Preferably, there are multiple anti-collision plates, which are evenly distributed on the four outer sides of the shell, and the anti-collision plates are matched with the shell.

[0010] Preferably, heat dissipation holes are provided through both sides of the housing, and a plurality of heat dissipation holes are provided, which are evenly distributed on both sides of the housing.

[0011] Preferably, a gap is left between the anti-collision plate and the shell.

[0012] Preferably, the protective pad is located at the outer corner of the battery cell body, and the protective pad corresponds to the battery cell body.

[0013] Compared with the prior art, the present invention provides a battery cell anti-collision protection device, which has the following beneficial effects: (1) In this utility model, the top cover is opened and the battery cell body is fixed inside the housing. Then the top cover is closed to form a basic protective structure. When an external object hits the device, the anti-collision plate first bears the impact and pushes the rear telescopic rod to move inward, so that the protective pad at the end of the telescopic rod contacts the corner of the battery cell body. During this process, the spring on the outside of the telescopic rod is compressed to generate a reverse buffering effect, which effectively absorbs and disperses the impact energy and reduces the direct impact of the external force on the housing. This mechanism not only avoids direct contact between external objects and the housing, but also prevents the deformation of the housing caused by the collision, thereby maintaining the structural integrity of the internal battery cell body. At the same time, the protective pad's covering buffering of the corner of the battery cell further strengthens the local protection of key parts, and improves the safety and reliability of the battery cell body in the impact environment, thereby helping to improve the protection effect of the battery cell body.

[0014] (2) In this utility model, the heat dissipation holes evenly distributed on both sides of the shell constitute the main heat dissipation channel of the battery cell body, which can effectively dissipate the heat generated during operation in a timely manner, thereby maintaining the stable operation of the battery cell body at a suitable temperature. At the same time, the reinforcing blocks installed at the four corners inside the shell enhance the overall structural strength and rigidity of the shell, which not only directly improves the shell's resistance to deformation and its firmness, but also indirectly enhances the device's protective performance in the face of physical impact by strengthening its overall load-bearing frame, thereby further improving its reliability and safety.

[0020] Please see Figure 1-4 A battery cell anti-collision protection device includes a housing 1. A battery cell body 7 is fixedly installed at the middle position of the upper surface of the bottom end of the housing 1. The battery cell body 7 matches the housing 1, and the housing 1 can protect the battery cell body 7. A telescopic rod 3 is provided through the outer surface of the housing 1. One end of the telescopic rod 3 is fixedly connected to an anti-collision plate 4 on the outside of the housing 1, and the other end of the telescopic rod 3 is fixedly connected to a protective pad 8 inside the housing 1. A spring 5 is sleeved on the outer surface of the telescopic rod 3 between the anti-collision plate 4 and the housing 1. When the housing 1 collides with the outside, a spring 5 is provided. When an external object touches the anti-collision plate 4, the anti-collision plate 4 will push the telescopic rod 3 to move. When the telescopic rod 3 moves, the protective pad 8 at one end of the telescopic rod 3 will contact the corner of the battery cell body 7. At this time, the anti-collision plate 4 will squeeze the spring 5 on the outer surface of the telescopic rod 3. Through the use of the spring 5, the adverse effects of external impact force on the shell 1 can be reduced, the protective barrier of the shell 1 can be improved, and external objects can be prevented from directly contacting the shell 1, thereby preventing the shell 1 from deforming and improving the protection effect of the battery cell body 7.

[0021] Please see Figure 2 and Figure 3 The shell 1 is fixedly connected with a reinforcing block 9. There are multiple reinforcing blocks 9, which are evenly distributed at the four corners inside the shell 1. The reinforcing blocks 9 match the shell 1. By using the reinforcing blocks 9, the four corners inside the shell 1 can be reinforced, thereby strengthening the shell 1, improving its strength, and further improving its impact resistance.

[0022] Please see Figure 1 and Figure 2 The telescopic rod 3 is movably connected to the housing 1, which allows the telescopic rod 3 to move normally on the housing 1, thereby allowing the anti-collision plate 4 and the protective pad 8 to move normally, facilitating the protection of the housing 1.

[0023] Please see Figure 1 and Figure 4 The top cover 2 is provided on the top of the housing 1. The top cover 2 is threadedly connected to the threaded hole on the top surface of the housing 1 by bolts. The battery cell body 7 is fixedly installed in the housing 1 by opening the top cover 2 and by closing the top cover 2. The battery cell body 7 can be protected by using the housing 1 and the top cover 2.

[0024] Please see Figure 1 , Figure 2 and Figure 4 Multiple anti-collision plates 4 are provided, and the multiple anti-collision plates 4 are evenly distributed on the four sides of the outer side of the housing 1. The anti-collision plates 4 are matched with the housing 1. By using multiple anti-collision plates 4, the outer perimeter of the housing 1 can be protected, the blind spots of protection are reduced, and the protection effect of the battery cell body 7 can be improved.

[0025] Please see Figure 1 and Figure 2 The two sides of the housing 1 are provided with heat dissipation holes 6. There are multiple heat dissipation holes 6, and the multiple heat dissipation holes 6 are evenly distributed on the two sides of the housing 1. Through the use of heat dissipation holes 6, the heat generated by the battery cell body 7 in the housing 1 during use can be dissipated, and the normal heat dissipation of the battery cell body 7 can be maintained.

[0026] Please see Figure 1 and Figure 2 A gap exists between the anti-collision plate 4 and the shell 1, which can maintain the normal heat dissipation of the heat dissipation hole 6, avoid heat accumulation, and facilitate heat dissipation of the battery cell body 7.

[0027] Please see Figure 2 and Figure 3 The protective pad 8 is located at the outer corner of the battery cell body 7. The protective pad 8 corresponds to the battery cell body 7. By using the protective pad 8, the corners of the battery cell body 7 can be protected, further improving the protection effect of the battery cell body 7.

[0028] Working principle: In use, first open the top cover 2, fix the battery cell body 7 in the housing 1, and close the top cover 2. The use of the housing 1 and the top cover 2 can protect the battery cell body 7. When the housing 1 collides with the outside, the external object will first touch the anti-collision plate 4. When it touches the anti-collision plate 4, the anti-collision plate 4 will push the telescopic rod 3 to move. When the telescopic rod 3 moves, the protective pad 8 at one end of the telescopic rod 3 will contact the corner of the battery cell body 7. At this time, the anti-collision plate 4 will compress the spring 5 on the outer surface of the telescopic rod 3. Through the use of the spring 5, the adverse effects of external impact on the housing 1 can be reduced, thus improving the protection of the housing 1. The shield prevents external objects from directly contacting the housing 1, thus preventing deformation of the housing 1 and improving the protection of the battery cell body 7. The use of protective pads 8 can protect the corners of the battery cell body 7, further improving the protection of the battery cell body 7. The use of heat dissipation holes 6 can dissipate the heat generated by the battery cell body 7 during use in the housing 1, maintaining normal heat dissipation of the battery cell body 7. Secondly, the use of reinforcing blocks 9 can reinforce the four corners inside the housing 1, thereby strengthening the housing 1, improving its strength, and further improving its impact resistance.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
