Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of batteries, and more specifically, to a connecting member, a battery, and an electronic device. Background Art

[0002] The electrical connection between the battery cell and the outside is achieved by electrically connecting the tab and the terminal. When welding the tab and the terminal, a relatively long tab is required to achieve the welding with the terminal. After the two are welded, the tab needs to be bent into the interior of the housing, and even needs to be bent several layers. In this case, on the one hand, it is difficult to control the bending of the tab, and on the other hand, the bent tab also occupies a relatively large volume of the housing.

[0003] In view of this, a new technical solution is needed to solve the above technical problems. Summary of the Utility Model

[0004] The purpose of the present application is to provide a new technical solution for a connecting member, a battery, and an electronic device.

[0006] The connecting member includes:

[0007] A first connecting portion for connecting to one of the tab and the terminal;

[0008] A second connecting portion for connecting to the other of the tab and the terminal;

[0009] An intermediate connecting portion, one end of the intermediate connecting portion is connected to the first connecting portion, and the other end is connected to the second connecting portion. The intermediate connecting portion is configured to be capable of generating elastic deformation.

[0010] Optionally, the intermediate connecting portion can be stretched to generate elastic deformation.

[0011] Optionally, the intermediate connecting portion is a structure formed by winding a metal sheet into a spiral shape.

[0012] Optionally, the intermediate connecting portion is disposed outside the first connecting portion.

[0013] Optionally, the intermediate connecting portion is a structure formed by bending a metal sheet at least once.

[0018] In a third aspect, an embodiment of the present application further provides an electronic device. The electronic device includes the battery as described in the second aspect.

[0019] According to the embodiments of the present application, by using a connecting member capable of elastic deformation to weld the tab and the terminal, on the one hand, it avoids welding the tab and the terminal by bending the tab, thereby avoiding the problem that the bent tab occupies a relatively large amount of space in the housing. On the other hand, by using a connecting member capable of elastic deformation to weld the tab and the terminal, the positions of the first connecting portion and the second connecting portion can be adjusted, and connection problems caused by relative position changes between the tab and the terminal can be reduced.

[0033] It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, further discussion thereof in subsequent drawings is not required.

[0034] A connector 1 provided by an embodiment of the present application is used to connect the pole column 21 and the tab 22 of the battery 2. Specifically, the connector 1 has an intermediate connecting portion 12 that can generate elastic deformation. When welding the pole column 21 and the tab 22 together through the connector 1, the connector 1 can be manipulated, and the intermediate connecting portion 12 generates elastic deformation so that the first connecting portion 10 or the second connecting portion 11 moves to a set position (the set position is the position where the tab 22 is located or the position where the pole column 21 is located) for welding. The battery 2 can be a steel shell button battery 2 with a fully sealed structure, and the pole column 21 can be an aluminum pole column 21.

[0035] Refer to Figure 1 and Figure 2 , the connector 1 includes a first connecting portion 10, a second connecting portion 11, and an intermediate connecting portion 12. The first connecting portion 10 is used to connect to one of the tab 22 and the pole column 21; the second connecting portion 11 is used to connect to the other of the tab 22 and the pole column 21; one end of the intermediate connecting portion 12 is connected to the first connecting portion 10, and the other end is connected to the second connecting portion 11. The intermediate connecting portion 12 is configured to be able to generate elastic deformation.

[0036] In an embodiment of the present application, the connecting member 1 includes a first connecting portion 10, a second connecting portion 11, and an intermediate connecting portion 12. The connecting member 1 may be an integrally formed structural member, or the first connecting portion 10 and the intermediate connecting portion 12 may be connected together by an additional connecting member, and / or the second connecting portion 11 and the intermediate connecting portion 12 may also be connected together by an additional connecting member. Optionally, the connecting member may be a buckle or a fastener, etc.

[0037] The first connecting portion 10 is used to connect to one of the tab 22 and the terminal 21, and the second connecting portion 11 is used to connect to the other of the tab 22 and the terminal 21. In one example, the first connecting portion 10 is connected to the tab 22, and the second connecting portion 11 is connected to the terminal 21. More specifically, the first connecting portion 10 and the tab 22 are welded, and the second connecting portion 11 and the terminal 21 are welded. Optionally, both the first connecting portion 10 and the second connecting portion 11 may be in a sheet structure, a block structure, or a strip structure. Considering the welding reliability between the connecting portion and the tab 22 or the terminal 21, and considering that the connecting portion does not occupy too much volume of the battery 2 housing 20, both the first connecting portion 10 and the second connecting portion 11 may be in a sheet structure.

[0038] It should be noted that in this embodiment, the intermediate connecting portion 12 is a bridge connecting the first connecting portion 10 and the second connecting portion 11. The intermediate connecting portion 12 can produce elastic deformation to allow a certain degree of flexibility and mobility between the first connecting portion 10 and the second connecting portion 11 to adapt to the relative position change between the tab 22 and the terminal 21.

[0039] Specifically, the intermediate connecting portion 12 is configured to be able to produce elastic deformation. This means that the intermediate connecting portion 12 is usually made of an elastic material, such as a metal spring sheet, rubber, or other elastic plastics. This design enables the connecting member 1 to maintain its integrity when subjected to pressure or tension, while allowing a certain amount of deformation to adapt to different situations.

[0040] For example, when the first connecting portion 10 is welded to the pole column 21 and the second connecting portion 11 needs to be welded to the tab 22, during welding, the first connecting portion 10 can be first welded to the pole column 21, and then the connecting member 1 is operated. The middle connecting portion 12 of the connecting member 1 undergoes elastic deformation (the connecting member 1 can be stretched or compressed). For example, taking stretching the connecting member 1 as an example, the connecting member 1 is stretched so that the second connecting portion 11 of the connecting member 1 is pulled out of the housing 20, and then the second connecting portion 11 is welded to the tab 22. When the second connecting portion 11 is welded to the tab 22, the connecting member 1 is released, and the elastic deformation of the connecting member 1 is restored. By using the connecting member 1 that can produce elastic deformation to connect the tab 22 and the pole column 21, it is convenient to weld the tab 22 and the pole column 21, avoiding the need to bend the tab 22 to achieve the connection between the tab 22 and the pole column 21. In addition, by welding the tab 22 and the pole column 21 through the connecting member 1, it is avoided that the connecting member 1 occupies too much volume of the housing 20 of the battery 2.

[0041] Therefore, in the embodiment of the present application, by using the connecting member 1 that can produce elastic deformation to weld the tab 22 and the pole column 21, on the one hand, it is avoided to weld the tab 22 and the pole column 21 by bending the tab 22, and thus the problem that the bent tab 22 occupies more space of the housing 20 is avoided. On the other hand, by using the connecting member 1 that can produce elastic deformation to weld the tab 22 and the pole column 21, the positions of the first connecting portion 10 and the second connecting portion 11 can be adjusted, and the connection problems caused by the relative position change between the tab 22 and the pole column 21 can be reduced.

[0042] In one embodiment, referring to Figure 1 and Figure 2 , the middle connecting portion 12 can be stretched to produce elastic deformation.

[0043] In this embodiment, the middle connecting portion 12 adopts a stretchable structural design, allowing it to deform when subjected to a tensile force. This deformation is elastic, meaning that when the external force disappears, the middle connecting portion 12 can return to its original shape and size. This design can make the connecting member 1 occupy less space in the housing 20 of the battery 2, rationally utilize the internal space of the housing 20 of the battery 2, and improve the performance of the battery 2.

[0044] Specifically, when it is necessary to connect the tab 22 and the pole column 21, a tensile force can be applied to the middle connecting portion 12 to stretch it and adapt to the distance between the tab 22 and the pole column 21. Since the middle connecting portion 12 has elasticity, it can adapt to this change in distance within a certain range.

[0045] Once the middle connecting portion 12 is stretched to an appropriate position, the middle connecting portion 12 can be tightly connected to the tab 22 and the pole column 21 to ensure the stability and reliability of the electrical contact.

[0046] When the external force disappears, the intermediate connecting portion 12 will utilize its elastic property to return to its original shape, thereby maintaining the stability and durability of the connection.

[0047] In one embodiment, referring to Figure 1 , the intermediate connecting portion 12 is a structure formed by winding a metal sheet into a spiral shape.

[0048] In this embodiment, the spiral structure enables the metal sheet to undergo elastic deformation when subjected to an external force. When the external force disappears, the metal sheet can quickly return to its original shape, maintaining the stability and reliability of the connection. Additionally, by adjusting the number of turns and pitch of the spiral, it is possible to adapt to different distances between the tab 22 and the terminal 21. Moreover, the metal sheet has good elasticity and ductility, and can withstand multiple stretching and recovery processes without being easily damaged. This ensures the stability and reliability of the intermediate connecting portion 12 during long-term use. For example, the material of the metal sheet can be stainless steel or aluminum.

[0049] Optionally, the intermediate connecting portion 12 can be a semi-spiral structure or a full-spiral structure.

[0050] Furthermore, the spiral-shaped connecting member 1 in the battery 2 design, especially in the application of connecting the terminal 21 and the tab 22, not only plays a crucial connecting role, but also can effectively improve the noise state of the battery 2 by adjusting the spiral direction and the winding forward and reverse directions with respect to the core.

[0051] Specifically, when the spiral direction of the spiral-shaped connecting member 1 matches the winding direction of the core, their interaction can produce a "damping" effect, reducing the noise generated inside the battery 2. For example, if the connecting member 1 has a reverse spiral direction with respect to the core winding direction, it can be used to suppress noise. On the contrary, if the spiral direction does not match the winding direction, it may exacerbate the generation of vibration and noise.

[0052] In addition, by adjusting the winding forward and reverse directions of the spiral-shaped connecting member 1 with respect to the core, the noise state of the battery 2 can be further improved. This is because different winding forward and reverse directions will cause changes in the distribution of internal stress and vibration in the battery 2, thereby affecting the generation and propagation of noise.

[0053] In one embodiment, referring to Figure 1 , the intermediate connecting portion 12 is disposed around the outer side of the first connecting portion 10.

[0054] In this embodiment, the intermediate connecting portion 12 being disposed around the outer side of the first connecting portion 10 means that the intermediate connecting portion 12 extends along the periphery of the first connecting portion 10 to form a continuous ring. This structure can ensure close contact between the intermediate connecting portion 12 and the first connecting portion 10, thereby providing better stability and reliability.

[0055] Referring toFigure 1 The connecting member 1 is in a spiral structure as a whole. The first connecting portion 10 is the starting end of the spiral structure, and the second connecting portion 11 is the end of the spiral structure. The connecting member 1 is an integrally formed structural member.

[0056] In one embodiment, referring to Figure 2 the intermediate connecting portion 12 is a structure formed by bending a metal sheet at least once.

[0057] Specifically, the metal sheet has good elasticity, ductility and strength. Therefore, the intermediate connecting portion 12 uses the metal sheet as the basic material. For example, the material of the metal sheet can be stainless steel or aluminum.

[0058] In this embodiment, the intermediate connecting portion 12 is a component with a specific bending structure. Specifically, the metal sheet is subjected to at least one bending treatment to form a structure with a bent portion. Such bending can be a simple bend or multiple complex bends. In addition, the bending structure enables the intermediate connecting portion 12 to have a certain degree of adjustability in length, shape and angle. Therefore, the connecting member 1 can adapt to the tab 22 and the terminal 21 with different sizes and shapes, improving the flexibility and versatility of the connection.

[0059] Specifically, due to the elasticity of the bent portion of the metal sheet, the intermediate connecting portion 12 can generate elastic deformation when subjected to an external force. This deformation enables the connecting member 1 to adapt to different connection distances and angles and maintain the stability of the connection.

[0060] Through the bending design of the metal sheet, a complex connection structure can be realized in a limited space. This helps to achieve a stable electrical connection inside the compact battery 2 housing 20.

[0061] Referring to Figure 2 the first connecting portion 10 is in a semi-circular structure, and the second connecting portion 11 is also in a semi-circular structure. The intermediate connection is a component with a bending structure. It should be noted that the structures of the first connecting portion 10 and the second connecting portion 11 include but are not limited to semi-circular structures, and the shapes of the first connecting portion 10 and the second connecting portion 11 can be adjusted according to the shapes of the tab 22 and the terminal 21.

[0062] In one embodiment, referring to Figure 2 the intermediate connecting portion 12 is in a "bow" shape structure.

[0063] In this embodiment, the intermediate connecting portion 12 is in a "bow" shape structure, or a combined structure in which multiple "bow" shape structures are connected together. This structural design enables the connecting member 1 to have good elasticity and bending ability.

[0064] Specifically, due to the natural bending characteristics of the "bow" - shaped structure, the middle connecting portion 12 can undergo elastic deformation when subjected to an external force. This deformation allows the connecting portion to adapt to different connection distances and angles, ensuring the stability and reliability of the connection.

[0065] It should be noted that the shape of the middle connecting portion 12 includes but is not limited to a "bow" - shaped structure.

[0066] In one embodiment, referring to Figure 1 and Figure 2 , when the middle connecting portion 12 does not undergo elastic deformation, the connecting member 1 is in a sheet - like structure.

[0067] In this embodiment, when the connecting member 1 does not undergo elastic deformation, the middle connecting portion 12 maintains its original designed shape and structural characteristics. Specifically, when the middle connecting portion 12 does not undergo elastic deformation, the entire connecting member 1 presents a sheet - like structure. The sheet - like structure means that the connecting member 1 is relatively flat in appearance and has a relatively small volume. In this way, when applied to the battery 2 structure, the connecting member 1 occupies less space in the battery 2 housing 20.

[0068] In one embodiment, the thickness range of the connecting member 1 is within 0.1 mm.

[0069] In this embodiment, when the connecting member 1 does not undergo elastic deformation, the thickness of the connecting member 1 is controlled within 0.1 mm. The connecting member 1 occupies less space in the housing 20, rationally uses the internal space of the battery housing 20, and improves the battery performance.

[0070] Referring to Figure 3 and Figure 4 , the embodiment of the present application also provides a battery 2. For example, the battery 2 includes but is not limited to a button battery.

[0071] The battery 2 includes the connecting member 1 as described above. Specifically, the connecting member 1 connects the pole column 21 and the pole ear 22. For example, the battery core of the battery 2 includes a first pole ear and a second pole ear. The first pole ear is connected to the battery 2 housing. The pole column 21 and the battery 2 housing are isolated by an insulating layer 23. The second pole ear is connected to the pole column 21 through the connecting member 1.

[0072] The embodiment of the present application also provides an electronic device. The electronic device includes the battery 2 as described above. For example, the electronic device includes but is not limited to headphones, tablet computers, wearable devices, etc.

[0073] In the above - mentioned embodiments, the differences between the various embodiments are mainly described. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a more optimal embodiment. Considering the simplicity of the writing, it will not be elaborated here.
