Technical Field

[0001] The utility model belongs to the technical field related to lithium battery steel shells, and particularly relates to a ternary lithium battery steel shell for a medical electric saw. Background Art

[0002] Ternary lithium batteries are a type of lithium-ion battery that typically uses a combination of nickel (Ni), cobalt (Co) and manganese (Mn) as positive electrode materials. They are a relatively new type of lithium-ion battery and are increasingly used in medical devices due to their excellent performance. Medical chainsaws are often used during surgery, especially in plastic surgery and orthopedic surgery. Such equipment requires batteries with high energy density, long service life and reliable safety. Ternary lithium batteries have higher energy density than traditional lithium batteries and can provide longer working time. They are suitable for equipment such as medical chainsaws that require instantaneous high power output. As the medical device industry gradually develops towards intelligence, convenience and high stability, the demand for lithium batteries in medical power tools and mobile devices is also increasing.

[0003] However, the existing lithium battery steel shell is easily deformed when it is directly subjected to external impact or squeeze collision, and the seismic performance of the lithium battery steel shell is poor. Long-term external vibration may affect the normal working state of the lithium battery. Utility Model Content

[0004] The purpose of the present utility model is to provide a ternary lithium battery steel shell for a medical electric saw, so as to solve the problem proposed in the above background technology that the existing lithium battery steel shell is easily deformed when directly subjected to external impact or extrusion collision, and the lithium battery steel shell has poor shock resistance, and long-term external vibration may cause the normal working state of the lithium battery to be affected.

[0005] To achieve the above-mentioned object, the present utility model provides the following technical solutions: a ternary lithium battery steel shell for a medical electric saw, comprising a battery shell and a battery top cover arranged on the top of the battery shell;

[0006] The battery top cover is provided with a battery cap, and the bottom of the battery shell is provided with a bottom cover;

[0007] A plurality of heat dissipation fins are vertically arranged on the outside of the battery shell, a plurality of reinforcement rings are horizontally arranged between the heat dissipation fins, a heat dissipation shell is arranged on the outside of the heat dissipation fins, a plurality of heat dissipation cavities are formed between the heat dissipation fins and the reinforcement rings, a plurality of shock-resistant protective shells are arranged on the outside of the heat dissipation shell, a plurality of springs are arranged between the shock-resistant protective shells and the heat dissipation shell, and a buffer block is also arranged between the shock-resistant protective shells and the heat dissipation shell.

[0008] Preferably, splicing blocks are respectively provided on both sides of the shock-resistant protective shell, and the multiple shock-resistant protective shells are spliced ​​together through the splicing blocks. The multiple shock-resistant protective shells are spliced ​​into a whole outside the heat dissipation shell.

[0009] Preferably, a fixing seat is provided inside the anti-seismic protective shell, the fixing seat is integrally connected to the anti-seismic protective shell, and the spring is fixedly connected to the fixing seat.

[0010] Preferably, a plurality of fixing blocks are provided on the outside of the heat dissipation housing, the fixing blocks are welded to the heat dissipation housing, the spring is sleeved with the fixing blocks, and the fixing blocks can limit the bottom of the spring.

[0011] Preferably, the buffer block is filled between the shock-resistant protective shell and the heat dissipation shell. The buffer block is made of flexible rubber material. When the shock-resistant protective shell is impacted, the buffer block can be compressed and extended to both sides.

[0012] Preferably, the heat dissipation shell is integrally connected to the heat dissipation fins, and the heat dissipation fins are integrally connected to the battery shell, so that the heat on the battery shell can be transferred to the heat dissipation shell through the heat dissipation fins.

[0013] Preferably, the reinforcement ring is welded to the heat dissipation fins, and the reinforcement ring can enhance the impact resistance of the battery housing.

[0014] Compared with the prior art, the present invention provides a ternary lithium battery steel shell for medical electric saws, which has the following beneficial effects:

[0015] When the lithium battery encounters external impact, the shockproof protective shell can effectively deform and absorb the impact force. When the shockproof protective shell is compressed inward, the synergistic effect of the spring and the buffer block can greatly reduce the pressure applied to the lithium battery steel shell, thereby reducing the risk of deformation or damage. This buffer mechanism makes the lithium battery safer and more reliable in the face of various extreme environments. The design of the fixing seat and the fixing block can stabilize the spring to avoid twisting or deformation during compression. It ensures that the spring and the buffer block can always be in the best condition to maximize the effect. Multiple shockproof protective shells are connected to each other by splicing blocks. When one of the shells is impacted When hit, the energy will be effectively dispersed to the adjacent protective shells. This dispersion effect can reduce the force on any single protective shell, reduce the risk of damage to the entire system, and improve the overall protection efficiency. The buffer block is made of flexible material and can extend to both sides when under pressure, which means that it can adapt to different types of impact and deformation and provide more flexible protection. This adaptability can cope with a variety of external environmental conditions, such as falls, collisions or vibrations, ensuring that lithium batteries can be protected in various situations. By effectively absorbing and buffering impact forces, the probability of damage to internal and external structures is reduced, which can significantly extend the service life of lithium batteries.

[0016] By setting up heat dissipation fins, heat dissipation shells and reinforcement rings, the battery can dissipate heat efficiently during operation. The design of the heat dissipation fins can increase the contact area with the air, effectively promoting the conduction and dissipation of heat. The heat generated by the battery during use can be quickly transferred to the heat dissipation fins through the battery shell, and then to the heat dissipation shell. This coherent heat conduction path ensures that the battery can maintain a relatively stable temperature under high-load operation, preventing performance degradation or damage caused by overheating. Through the setting of the heat dissipation structure, heat can be dissipated in time, significantly reducing the safety hazards of the battery caused by high temperature. The gap between the heat dissipation shell and the shock-resistant protective shell further assists in heat dissipation, forming a good heat flow channel, ensuring that the battery is always within a safe temperature range. The addition of the reinforcement ring not only improves the structural strength of the battery shell, but also effectively improves its impact resistance. When impacted by external force, the battery shell can better maintain its shape and reduce the risk of deformation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides Figure 1-5The ternary lithium battery steel shell for medical electric saw shown includes a battery shell 8 and a battery top cover 2 arranged on the top of the battery shell 8;

[0025] A battery cap 1 is provided on the battery top cover 2, and a bottom cover 9 is provided at the bottom of the battery shell 8;

[0026] A plurality of heat dissipation fins 5 are vertically arranged on the outside of the battery shell 8, a plurality of reinforcement rings 6 are horizontally arranged between the heat dissipation fins 5, a heat dissipation shell 3 is arranged on the outside of the heat dissipation fins 5, a plurality of heat dissipation cavities 7 are formed between the heat dissipation fins 5 and the reinforcement rings 6, a plurality of shock-resistant protective shells 4 are arranged on the outside of the heat dissipation shell 3, a plurality of springs 14 are arranged between the shock-resistant protective shell 4 and the heat dissipation shell 3, and a buffer block 11 is also arranged between the shock-resistant protective shell 4 and the heat dissipation shell 3.

[0027] In this embodiment, the lithium battery steel shell is one of the important components of the lithium battery, and it mainly plays the following roles. First, the battery shell 8 provides a solid shell for the battery, which can effectively resist external impact, pressure and other mechanical stresses, and prevent internal materials from being damaged by external forces. The lithium battery contains electrolyte, and the battery shell 8 can prevent the electrolyte from leaking, avoiding pollution to the environment or damage to the equipment. The battery shell 8 has a certain thermal conductivity, which can help the battery dissipate heat and reduce the temperature of the battery during the charging and discharging process. This is very important for improving the safety and performance of the battery. When the battery is short-circuited, overcharged, over-discharged or other abnormal conditions occur, the battery shell 8 can provide certain structural support to reduce the risk of battery expansion, explosion or fire. Although the battery shell 8 is conductive, by designing an insulating layer inside, internal short circuits can be prevented to ensure the normal operation of the battery. The battery shell 8 can effectively encapsulate the various components inside the battery, prevent the intrusion of external substances such as moisture and dust, and extend the service life of the battery.

[0028] like Figure 1 、 Figure 3 and Figure 4 As shown, splicing blocks 12 are respectively provided on both sides of the earthquake-resistant protective shell 4, and multiple earthquake-resistant protective shells 4 are spliced ​​together through the splicing blocks 12. Multiple earthquake-resistant protective shells 4 are spliced ​​into a whole on the outside of the heat dissipation shell 3, and a fixing seat 13 is provided on the inside of the earthquake-resistant protective shell 4. The fixing seat 13 is integrated with the earthquake-resistant protective shell 4, and the spring 14 is fixedly connected to the fixing seat 13. Multiple fixing blocks 10 are provided on the outside of the heat dissipation shell 3, and the fixing blocks 10 are welded to the heat dissipation shell 3. The spring 14 is sleeved with the fixing block 10. The fixing block 10 can limit the bottom of the spring 14, and the buffer block 11 is filled between the earthquake-resistant protective shell 4 and the heat dissipation shell 3. The buffer block 11 is made of flexible rubber material. When the earthquake-resistant protective shell 4 is impacted, the buffer block 11 can be compressed and extended to both sides.

[0029] Preferably, through the arrangement of the shock-resistant protective shell 4, the fixing seat 13, the spring 14, the fixing block 10, the buffer block 11 and the splicing block 12, when the lithium battery encounters an external impact, the shock-resistant protective shell 4 will move inward after being impacted. At this time, the shock-resistant protective shell 4 will compress the spring 14 inward, and at the same time, the buffer block 11 between the shock-resistant protective shell 4 and the heat dissipation shell 3 will be compressed. Due to the characteristics of the flexible material of the buffer block 11, the buffer block 11 will extend to both sides. In this process, the spring 14 and the buffer block 11 can simultaneously buffer and absorb the external impact to prevent the lithium battery steel shell from being deformed due to external impact, and the buffer block 11 and the spring 14 can also play a good role in absorbing external vibrations. The fixing seat 13 and the fixing block 10 can fix the spring 14 to prevent the spring 14 from twisting and deforming during the compression process. Multiple shock-resistant protective shells 4 are connected to each other through the splicing block 12. When one of them is impacted, its impact will be transmitted to the adjacent shock-resistant protective shell 4, thereby sharing the impact and protecting the internal structure.

[0030] like Figure 2 As shown, the heat dissipation shell 3 is integrally connected to the heat dissipation fins 5, and the heat dissipation fins 5 are integrally connected to the battery shell 8. The heat on the battery shell 8 can be transferred to the heat dissipation shell 3 through the heat dissipation fins 5. The reinforcement ring 6 is welded to the heat dissipation fins 5, and the reinforcement ring 6 can enhance the impact resistance of the battery shell 8.

[0031] Preferably, through the arrangement of the heat dissipation fins 5, the heat dissipation shell 3 and the reinforcement ring 6, when heat is generated inside the battery, it will be transferred to the heat dissipation fins 5 through the battery shell 8, and then transferred to the heat dissipation shell 3, and finally the heat is dissipated from the battery through the heat dissipation shell 3 and the gap between the heat dissipation shell 3 and the shock-resistant protective shell 4 to prevent the battery from being damaged due to overheating. The reinforcement ring 6 can effectively enhance the impact resistance of the battery shell 8 and avoid deformation of the battery shell 8 during impact.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
