Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a battery top cover and a battery. Background Technology

[0002] Currently, with the continuous development of the energy storage industry, lithium-ion batteries have been widely used due to their high capacity and other excellent characteristics. A lithium-ion battery mainly consists of an aluminum casing and a top cover. The aluminum casing has an opening, and the top cover seals the opening in the aluminum casing, thus forming a closed energy storage system. Within this closed system are corresponding energy storage structures and materials.

[0003] During the use of lithium-ion batteries, the charge-discharge cycles generate a large amount of heat and gas, which poses significant challenges to battery performance, safety, and maintenance. In particular, the accumulation of gas can cause the battery to swell, thereby affecting its reliability and lifespan.

[0004] In existing technologies, sensors are welded onto the battery top cover to effectively monitor key data such as temperature and pressure inside the battery. However, this process is not only complex but also hinders subsequent maintenance and replacement of the sensors, thus reducing production efficiency. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model provides a battery top cover and a battery. After the sensor module enters the receiving space through the clearance opening, the sensor module can be rotated around its rotation axis so that the second limiting part enters the limiting space after passing through the clearance space and abuts against the first limiting part. The air inlet is connected to the through hole, thereby installing the sensor module on the top cover body. The installation is convenient and facilitates the later maintenance and replacement of the sensor module, thus improving production efficiency.

[0006] The technical effects to be achieved by this utility model are realized through the following aspects:

[0007] In a first aspect, this utility model provides a battery top cover, comprising:

[0008] A top cover body, wherein a through hole is formed on the top cover body along a first direction;

[0009] A limiting component is provided on the top surface of the top cover body and around the through hole. The limiting component and the top cover body enclose a receiving space. A clearance opening is formed on the side of the limiting component away from the top cover body along a first direction. Clearance spaces are formed on opposite sides of the limiting component along a second direction. Limiting spaces are formed on opposite sides of the limiting component along a third direction. The clearance opening, the clearance spaces, and the limiting spaces are all connected to the receiving space. A first limiting part is provided on the limiting component near the limiting spaces.

[0010] A sensor module, wherein the width of the sensor module is smaller than the rotation diameter of the sensor module, an air inlet is provided at the bottom of the sensor module, and a second limiting part is provided on opposite sides along the length direction of the sensor module, the rotation diameter of the second limiting part being equal to the rotation diameter of the sensor module;

[0011] When the width direction of the sensor module is parallel to the third direction, the sensor module can enter the accommodating space from the clearance opening along the first direction so that the sensor module covers the through hole; the sensor module can rotate around the pivot so that the second limiting part enters the limiting space after passing through the clearance space and abuts against the first limiting part, and the air inlet is connected to the through hole.

[0012] In some implementations, the limiting component includes a first limiting member and a second limiting member disposed opposite to each other along the third direction, the limiting space includes a limiting groove formed on the first limiting member and the second limiting member, and the first limiting portion includes the inner wall surface of the limiting groove.

[0013] In this implementation, after the sensor module enters the accommodating space, the sensor module can be rotated around its rotation axis so that the second limiting parts located on opposite sides of the sensor module along the length direction enter the limiting grooves of the first and second limiting members respectively and abut against the inner wall of the limiting grooves. This allows the first and second limiting members to limit the sensor module on opposite sides along the length direction, thereby limiting the sensor module to the top cover body.

[0014] In some implementations, the inner wall surface of the limiting groove includes a first arc surface, and the outer surface of the second limiting part includes a second arc surface that mates with the first arc surface.

[0015] In some implementations, the first limiting member and / or the second limiting member includes a first limiting block and a second limiting block disposed opposite to each other along the second direction, the limiting groove is formed on the first limiting block and the second limiting block, and the second limiting part is disposed at the corner of the sensor module.

[0016] In this implementation, the sensor module can be rotated around its rotation axis so that its second limiting portion enters the limiting grooves of the first and second limiting blocks respectively, and abuts against the inner wall of the limiting grooves, thereby installing the sensor module onto the top cover body. The first and second limiting blocks respectively limit the angular position of the sensor module, thereby confining the sensor module to the top cover body.

[0017] In some implementations, the limiting component further includes a first connecting block and a second connecting block, wherein the first connecting block is connected to two first limiting blocks respectively, and the second connecting block is connected to two second limiting blocks respectively;

[0018] The clearance space includes clearance slots formed on the first connecting block and the second connecting block; or

[0019] The first connecting block and the second connecting block form the clearance space with the accommodating space.

[0020] In some implementations, the first limiting member and / or the second limiting member further include a third limiting block, which is connected to the first limiting block and the second limiting block respectively. The limiting groove is also formed on the third limiting block, and the second limiting part is also provided on the edge of the sensor module and extends along the length direction.

[0021] In some implementations, the first limiting part is provided with a first anti-torsion structure, and the second limiting part is provided with a second anti-torsion structure that cooperates with the first anti-torsion structure to limit the torsion of the sensor module.

[0022] In this implementation, when the second limiting part of the sensor module abuts against the first limiting part, the second anti-torsion structure and the first anti-torsion structure cooperate with each other to improve the anti-torsion performance of the sensor module and avoid the problem that the sensor module rotates relative to the top cover body or the limiting component, thereby affecting the monitoring of key data such as temperature and / or pressure inside the battery.

[0023] In some implementations, the first anti-torsion structure includes a snap-fit ​​hole formed on the first limiting portion, and the second anti-torsion structure includes a snap-fit ​​post provided on the second limiting portion; and / or

[0024] The first anti-torsion structure includes a snap-fit ​​post disposed on the first limiting portion, and the second anti-torsion structure includes a snap-fit ​​hole formed on the second limiting portion.

[0027] The housing includes a receiving cavity with an opening;

[0028] Electrode assemblies are installed within the accommodating cavity; and

A limiting component is disposed on the top surface of the top cover body and around the through hole. An accommodating space is formed between the limiting component and the top cover body. The limiting component has a clearance opening, a clearance space, and a limiting space communicating with the accommodating space on the side of the limiting component away from the top cover body in the first direction, on opposite sides along the second direction, and on opposite sides along the third direction, respectively. A first limiting part is provided on the limiting component near the limiting space, and a second limiting part is provided on opposite sides of the sensor module along the length direction. After the sensor module enters the accommodating space through the clearance opening, the sensor module can be rotated around its rotation axis to allow the second limiting part to pass through the clearance space and enter the limiting space, abutting against the first limiting part.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0050] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0051] Example 1:

[0052] Please see the appendix Figure 1 ~Appendix Figure 3 The battery top cover 1 of this utility model includes a top cover body 10, a limiting component 20, and a sensor module 30.

[0053] In this regard, please combine Figure 1 and Figure 2 , Figure 1 The diagram illustrates the structural relationship between the top cover body 10, the limiting component 20, and the sensor module 30 in this embodiment of the present invention. Figure 2 The specific structure of the limiting component 20 in this embodiment of the present invention is illustrated. For ease of description, an example of the first direction, the second direction, and the third direction is defined, as follows: Figure 1 and Figure 2 As shown, the XYZ coordinate axes are defined, where the first direction is parallel to the Z-axis, the second direction is parallel to the Y-axis, and the third direction is parallel to the X-axis. These three directions are orthogonal to each other. It is understandable that the first, second, and third directions may not be orthogonal, or may only be partially orthogonal.

[0054] Specifically, a through hole 11 is provided on the top cover body 10 along the first direction; a limiting component 20 is provided on the top surface of the top cover body 10 and around the through hole 11. The limiting component 20 and the top cover body 10 enclose a receiving space 21. A clearance opening 22 is formed on the side of the limiting component 20 away from the top cover body 10 along the first direction. Clearance spaces 23 are formed on opposite sides of the limiting component 20 along the second direction. Limiting spaces 24 are formed on opposite sides of the limiting component 20 along the third direction. The clearance opening 22, clearance spaces 23 and limiting spaces 24 are respectively connected to the receiving space 21. A first limiting part 25 is provided on the limiting component 20 near the limiting space 24. The width of the sensor module 30 is smaller than the rotation diameter of the sensor module 30. An air inlet 31 is provided at the bottom of the sensor module 30. A second limiting part 32 is provided on opposite sides of the sensor module 30 along the length direction. The rotation diameter of the second limiting part 32 is equal to the rotation diameter of the sensor module 30.

[0055] When the width direction of the sensor module 30 is parallel to the third direction, the sensor module 30 can enter the accommodating space 21 from the clearance opening 22 along the first direction so that the sensor module 30 covers the through hole 11; the sensor module 30 can rotate around the pivot so that the second limiting part 32 enters the limiting space 24 after passing through the clearance space 23 and abuts against the first limiting part 25, and the air inlet 31 communicates with the through hole 11.

[0056] In this embodiment, the limiting component 20 is disposed on the top surface of the top cover body 10 and around the through hole 11. A receiving space 21 is formed between the limiting component 20 and the top cover body 10. The limiting component 20 has a clearance opening 22 on the side facing away from the top cover body 10 along the first direction, clearance spaces 23 are formed on opposite sides along the second direction, and limiting spaces 24 are formed on opposite sides along the third direction. The clearance opening 22, clearance spaces 23, limiting spaces 24, and receiving space 21 are interconnected so that the sensor module 30 can be... The sensor module 30 enters the accommodating space 21 through the clearance opening 22 and covers the through hole 11 of the top cover body 10. The limiting component 20 is provided with a first limiting part 25 near the limiting space 24, and the sensor module 30 is provided with second limiting parts 32 on opposite sides along the length direction. After the sensor module 30 enters the accommodating space 21, the sensor module 30 can be rotated around the rotation axis of the sensor module 30 so that the second limiting part 32 abuts against the first limiting part 25, so as to install the sensor module 30 on the top cover body 10.

[0057] Specifically, during actual installation, when the width direction of the sensor module 30 is parallel to the third direction, since the width of the clearance opening 22 and the width of the accommodating space 21 are both greater than the width of the sensor module 30, and the length of the clearance opening 22 and the length of the accommodating space 21 are both greater than the length of the sensor module 30, the sensor module 30 can enter the accommodating space 21 from the clearance opening 22 along the first direction, so that the sensor module 30 covers the through hole 11, and the air inlet 31 of the sensor module 30 is connected to the through hole 11. Since the width of the sensor module 30 is smaller than the rotation diameter of the sensor module 30, and the rotation diameter of the second limiting part 32 is equal to the rotation diameter of the sensor module 30, the sensor module 30 can be rotated around its rotation axis so that the second limiting part 32 passes through the clearance space 23 and enters the limiting space 24 and abuts against the first limiting part 25. This allows the limiting component 20 to limit the sensor module 30 to the top cover body 10, preventing the sensor module 30 from coming out of the accommodating space 21 and causing the inability to effectively monitor key data such as the temperature and pressure inside the battery.

[0058] It is understood that after the sensor module 30 enters the accommodating space 21, the sensor module 30 covers the through hole 11. The air inlet 31 of the sensor module 30 may not be connected to the through hole 11. Instead, the air inlet 31 of the sensor module 30 is connected to the through hole 11 by rotating the sensor module 30 around its rotation axis. When it is necessary to disassemble the sensor module 30, the sensor module 30 can be rotated around its rotation axis to disengage the second limiting part 32 from the limiting space 24. That is, the second limiting part 32 and the first limiting part 25 are released from contact until the width direction of the sensor module 30 is parallel to the third direction. The sensor module 30 can then be removed from the accommodating space 21 along the first direction through the clearance 22, thereby replacing the sensor module 30 and improving the maintenance efficiency of the sensor module 30.

[0059] Furthermore, the sensor module 30 includes a sensor and a base. An air inlet 31 is provided at the bottom of the sensor, which is connected to a through hole 11 via the air inlet 31. Gas inside the battery can be transmitted to the sensor through the through hole 11 and the air inlet 31, thereby achieving active safety monitoring of the battery's internal state. The base is arranged around the bottom of the sensor, and a second limiting part 32 is provided on opposite sides of the base along its length. Specifically, the width of the sensor module 30 can be understood as the width of the base, and the width direction of the sensor module 30 is parallel to the width of the base; the length of the sensor module 30 can be understood as the length of the base, and the length direction of the sensor module 30 is parallel to the length of the base.

[0060] The rotation axis of the sensor module 30 can be understood as the rotation axis of the base, and the rotation diameter of the sensor module 30 is the same as the rotation diameter of the base. The rotation diameter of the base is equal to the rotation diameter of the second limiting part 32.

[0061] The battery top cover 1 described above has a top cover body 10 with a through hole 11 along a first direction. A limiting component 20 is disposed on the top surface of the top cover body 10 and around the through hole 11. An accommodating space 21 is formed between the limiting component 20 and the top cover body 10. The limiting component 20 has a clearance opening 22, a clearance space 23, and a limiting space 24 communicating with the accommodating space 21 on the side of the limiting component 20 away from the top cover body 10 in the first direction, on the opposite sides along the second direction, and on the opposite sides along the third direction. A first limiting part 25 is provided on the limiting component 20 near the limiting space 24. A second limiting part 32 is provided on the opposite sides of the sensor module 30 along the length direction. After the sensor module 30 enters the receiving space 21 through the clearance port 22, the sensor module 30 can be rotated around the rotation axis of the sensor module 30 so that the second limiting part 32 enters the limiting space 24 after passing through the clearance space 23 and abuts against the first limiting part 25. The air inlet 31 is connected to the through hole 11, thereby installing the sensor module 30 on the top cover body 10. The installation is convenient and facilitates the maintenance and replacement of the sensor module 30 in the later stage, thus improving production efficiency.

[0062] In some preferred embodiments, please refer to Figure 3 , Figure 3 The diagram illustrates the structural relationship between the first limiting member 26 and the second limiting member 27 in this embodiment of the present invention. Specifically, the limiting assembly 20 includes a first limiting member 26 and a second limiting member 27 disposed opposite to each other along a third direction. The limiting space 24 includes limiting grooves 241 formed on the first limiting member 26 and the second limiting member 27. The first limiting part 25 includes the inner wall surface of the limiting groove 241. When the sensor module 30 enters the accommodating space 21, the sensor module 30 can be rotated around its rotation axis so that the second limiting parts 32 disposed on opposite sides of the sensor module 30 along the length direction respectively enter the limiting grooves 241 of the first limiting member 26 and the second limiting member 27 and abut against the inner wall surface of the limiting grooves 241. This allows the first limiting member 26 and the second limiting member 27 to limit the sensor module 30 on opposite sides along the length direction, thereby limiting the sensor module 30 to the top cover body 10.

[0063] In some more preferred embodiments, the inner wall surface of the limiting groove 241 includes a first arc surface 2411, and the outer surface of the second limiting part 32 includes a second arc surface 321 that mates with the first arc surface 2411. When the sensor module 30 is rotated about its rotation axis, the second arc surface 321 and the first arc surface 2411 mate with each other, so that the second limiting part 32 can enter the limiting groove 241 more smoothly and abut tightly against the inner wall surface of the limiting groove 241, thereby improving assembly reliability.

[0064] Example 2:

[0065] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the limiting component 20 and the sensor module 30 of this utility model. Please refer to the appendix. Figure 4 .

[0066] The first limiting member 26 and / or the second limiting member 27 include a first limiting block 261 and a second limiting block 262 arranged opposite to each other along the second direction, a limiting groove 241 is formed on the first limiting block 261 and the second limiting block 262, and a second limiting part 32 is provided at the corner of the sensor module 30.

[0067] In this embodiment, the sensor module 30 can be rotated around its rotation axis so that the second limiting part 32 of the sensor module 30 enters the limiting groove 241 of the first limiting block 261 and the second limiting block 262 respectively, and abuts against the inner wall surface of the limiting groove 241, thereby installing the sensor module 30 on the top cover body 10. The first limiting block 261 and the second limiting block 262 respectively limit the corner positions of the sensor module 30, thereby limiting the sensor module 30 on the top cover body 10. It can be understood that the sensor module 30 has four corner positions, and the second limiting part 32 at two corner positions of the sensor module 30 distributed along the width direction abuts against the inner wall surface of the limiting groove 241 of the first limiting block 261 and the second limiting block 262 respectively.

[0068] Example 3:

[0069] The difference between this embodiment and Embodiment 2 is that this embodiment further optimizes the structure of the limiting component 20 and the sensor module 30 of this utility model. Please refer to the appendix. Figure 5 ~Appendix Figure 7 .

[0070] Please see below. Figure 5 , Figure 5 The diagram illustrates the structural relationship between the first connecting block 263 and the second connecting block 264 in this embodiment of the present invention. Specifically, the limiting component 20 further includes a first connecting block 263 and a second connecting block 264. The first connecting block 263 is connected to two first limiting blocks 261 respectively, and the second connecting block 264 is connected to two second limiting blocks 262 respectively. The clearance space 23 includes clearance grooves 231 formed on the first connecting block 263 and the second connecting block 264; or a clearance space 23 is formed between the first connecting block 263 and the second connecting block 264 and the accommodating space 21.

[0071] In this embodiment, after the sensor module 30 enters the accommodating space 21, the sensor module 30 can be rotated around the rotation axis of the sensor module 30 so that the second limiting part 32 can enter the limiting groove 241 after passing through the clearance groove 231 or the clearance space 23. The first connecting block 263 and the second connecting block 264 make the limiting component 20 more stable, thereby improving the reliability of the overall structure.

[0072] In some preferred embodiments, the first limiting member 26 and / or the second limiting member 27 further include a third limiting block 265, which is connected to the first limiting block 261 and the second limiting block 262 respectively. A limiting groove 241 is also formed on the third limiting block 265, and a second limiting part 32 is also provided on the edge of the sensor module 30 and extends along the length direction. When the sensor module 30 enters the accommodating space 21, the sensor module 30 can be rotated around its rotation axis so that the second limiting part 32, which is provided on the edge of the sensor module 30 and extends along the length direction of the sensor module 30, abuts against the inner wall surface of the limiting groove 241 formed on the third limiting block 265. This limits the edge of the sensor module 30 by the third limiting block 265, thereby limiting the sensor module 30 to the top cover body 10, thereby improving the installation stability between the sensor module 30 and the top cover body 10, and further ensuring the reliability of the sensor module 30 in monitoring key data such as temperature and / or pressure inside the battery.

[0073] In some preferred embodiments, please refer to Figure 6 , Figure 6 The diagram illustrates the structural relationship between the first anti-torsion structure 251 and the second anti-torsion structure 322 in this embodiment of the invention. Specifically, the first limiting part 25 is provided with the first anti-torsion structure 251, and the second limiting part 32 is provided with the second anti-torsion structure 322, which cooperates with the first anti-torsion structure 251 to limit the torsion of the sensor module 30. When the second limiting part 32 of the sensor module 30 abuts against the first limiting part 25, the second anti-torsion structure 322 and the first anti-torsion structure 251 cooperate with each other to improve the anti-torsion performance of the sensor module 30, preventing the sensor module 30 from rotating relative to the top cover body 10 or the limiting component 20, thereby affecting the monitoring of key data such as temperature and / or pressure inside the battery.

[0074] In some preferred embodiments, the first anti-torsion structure 251 includes a snap-fit ​​hole formed on the first limiting portion 25, and the second anti-torsion structure 322 includes a snap-fit ​​post formed on the second limiting portion 32; and / or the first anti-torsion structure 251 includes a snap-fit ​​post formed on the first limiting portion 25, and the second anti-torsion structure 322 includes a snap-fit ​​hole formed on the second limiting portion 32. The snap-fit ​​post snaps into the snap-fit ​​hole, so that the first limiting portion 25 and the second limiting portion 32 snap into each other, thereby causing the sensor module 30 to snap into the limiting component 20, thereby improving the anti-torsion performance of the sensor module 30 and making the overall structure more stable.

[0075] In some more preferred embodiments, the battery top cover 1 further includes a seal 40, which is disposed between the sensor module 30 and the top cover body 10 and surrounds the through hole 11. The seal 40 can ensure the sealing between the sensor module 30 and the top cover body 10, so that the sensor module 30 can accurately obtain information such as the internal air pressure and / or temperature of the battery through the air inlet 31 and the through hole 11, thereby achieving the purpose of active safety.

[0080] In this embodiment, the electrode assembly 60 is a cell formed by winding or stacking a separator, a positive electrode, and a negative electrode. The battery 2 described above can be a lithium-ion battery or a sodium-ion battery.

[0081] The battery 2 of this utility model has a top cover body 10 with a through hole 11 along a first direction. A limiting component 20 is disposed on the top surface of the top cover body 10 and around the through hole 11. An accommodating space 21 is formed between the limiting component 20 and the top cover body 10. The limiting component 20 has a clearance opening 22, a clearance space 23, and a limiting space 24 communicating with the accommodating space 21 on the side of the limiting component 20 away from the top cover body 10 in the first direction, on the opposite sides along the second direction, and on the opposite sides along the third direction. A first limiting part 25 is provided on the limiting component 20 near the limiting space 24. A second limiting part 32 is provided on the opposite sides of the sensor module 30 along the length direction. After the sensor module 30 enters the receiving space 21 through the clearance port 22, the sensor module 30 can be rotated around the rotation axis of the sensor module 30 so that the second limiting part 32 enters the limiting space 24 after passing through the clearance space 23 and abuts against the first limiting part 25. The air inlet 31 is connected to the through hole 11, thereby installing the sensor module 30 on the top cover body 10. The installation is convenient and facilitates the maintenance and replacement of the sensor module 30 in the later stage, thus improving production efficiency.
