Description

Technical Field

[0001] The present application belongs to the technical field of energy storage devices, and in particular, relates to a battery assembly and an electronic device. Background Art

[0002] Batteries are used as energy storage devices in electronic devices.

[0003] In the related art, a protection board is usually provided on the battery, and the battery is connected to other components in the electronic device through the protection board. However, the current protection board and the battery are usually connected by wires. When the battery has overcurrent, overheating, etc., the wires between the protection board and the battery are prone to leakage, and the wires between the protection board and the battery also increase the clutter of the device.

[0004] Therefore, there is an urgent need for a battery assembly and electronic device that can solve the above problems. Summary of the invention

[0005] The purpose of the present application is to provide a battery assembly and an electronic device, aiming to solve the problem of low protection and high clutter of batteries in traditional technologies.

[0006] A first aspect of an embodiment of the present application provides a battery assembly, the battery assembly comprising:

[0007] A battery having a first end surface, on which a first electrical connection contact and a second electrical connection contact are arranged at intervals;

[0008] a protection plate, arranged close to the first end surface and arranged on the first electrical connection contact and the second electrical connection contact; the protection plate is electrically connected to the first electrical connection contact and the second electrical connection contact respectively;

[0009] The battery assembly has a protection state, and in the protection state, a height between the first electrical connection contact and the first end surface is different from a height between the second electrical connection contact and the first end surface.

[0010] As can be seen from the above, on the one hand, the present application arranges the protection plate close to the first end face and on the first electrical connection contact and the second electrical connection contact, and the protection plate is electrically connected to the first electrical connection contact and the second electrical connection contact, respectively, which is beneficial to reducing the wire structure between the protection plate and the battery, which is beneficial to improving the protection of the battery and reducing the clutter between the protection plate and the battery; on the other hand, by setting the height of the first electrical connection contact from the first end face to be different from the height of the second electrical connection contact from the first end face, it is beneficial to reduce the risk of other metal structures contacting the positive and negative poles of the battery at the same time, causing a battery short circuit.

[0011] In some embodiments of the present application, in the protection state, a height between the first electrical connection contact and the first end surface is lower than a height between the second electrical connection contact and the first end surface.

[0012] In this way, other metal shell structures will be preferentially connected to the second electrical connection contact, while maintaining a certain distance from the first electrical connection contact, which is helpful to avoid other metal shell structures being directly connected to the positive and negative electrodes of the battery.

[0013] In some embodiments of the present application, an insulating structure is provided between the first electrical connection contact and the second electrical connection contact.

[0014] In this way, the insulating structure can isolate the first electrical connection contact from the second electrical connection contact, which is beneficial to avoid a short circuit between the first electrical connection contact and the second electrical connection contact, and further beneficial to avoid a short circuit between the positive and negative electrodes of the battery.

[0015] In some embodiments of the present application, the insulating structure is disposed around the first electrical connection contact.

[0016] This is helpful to improve the protection effect of the insulating structure on the first electrical connection contact.

[0017] In some embodiments of the present application, the insulating structure is a ring-shaped structure, the first electrical connection contact is arranged inside the ring of the insulating structure, and the second electrical connection contact is arranged outside the ring of the insulating structure.

[0018] In this way, the first electrical connection contact and the second electrical connection contact are completely separated, which is beneficial to optimizing the isolation effect of the insulation structure.

[0019] In some embodiments of the present application, the insulating structure is a silicone member, and the silicone member is disposed on the first end surface.

[0020] In this way, starting from the first end face, the insulating structure can play an isolating effect between the first electrical connection contact and the second electrical connection contact, which is beneficial to improving the isolating effect of the insulating structure.

[0021] In some embodiments of the present application, a height of the insulating structure is higher than a height of the first electrical connection contact.

[0022] In this way, the insulating structure can protect the first electrical connection contact in the height direction of the first electrical connection contact.

[0023] In some embodiments of the present application, the first electrical connection contact is the positive electrode of the battery, and the second electrical connection contact is the negative electrode of the battery.

[0024] In some embodiments of the present application, the second electrical connection contact is a first elastic member, which connects the first end surface and the protective plate; the height of the first elastic member from the first end surface is higher than the height of the first electrical connection contact from the first end surface.

[0025] In this way, the first elastic member can first contact the external conductive structure with the first electrical connection contact, which is beneficial to reduce the risk of the positive and negative electrodes of the battery being connected to the external conductive structure at the same time, thereby helping to avoid a short circuit between the positive and negative electrodes of the battery.

[0026] In some embodiments of the present application, the battery assembly also includes a second elastic member, and the battery assembly has a non-protective state. In the non-protective state, the second elastic member connects the first electrical connection contact and the protective plate; the sum of the height of the second elastic member and the height of the first electrical connection contact is equal to the height of the first elastic member.

[0027] In this way, when protection is not needed, the protection plate and the positive and negative electrodes of the battery can be connected through the second elastic member and the first elastic member. When protection is needed, the second elastic member can be removed.

[0028] In some embodiments of the present application, the first elastic member is configured so that, in a compressed state, a height of the first elastic member from the first end surface is equal to a height of the first electrical connection contact from the first end surface.

[0029] In this way, the protection plate can be connected to the first elastic member and the first electrical connection contact at the same time by compressing the first elastic member.

[0030] In some embodiments of the present application, the protective plate has a second end face arranged close to the first end face, and the second end face is provided with a first connecting portion and a second connecting portion, the second connecting portion is arranged around the first connecting portion, the first connecting portion is used to be electrically connected to the first electrical connection contact, and the second connecting portion is used to be electrically connected to the second electrical connection contact.

[0031] In this way, even after the protection board or the battery is rotated by a certain angle, the second electrical connection contact can still be connected to the second connection portion, which is beneficial to ensure the connection stability between the battery and the protection board.

[0032] In a second aspect, the present application also provides an electronic device, which includes the above-mentioned battery assembly.

[0033] In some embodiments of the present application, the electronic device further comprises a connecting wire, and the connecting wire is welded to the protective plate of the battery assembly without electricity.

[0034] This helps to avoid damaging the connection structure between the connecting wire and the protection plate due to live welding.

[0035] In some embodiments of the present application, the electronic device also includes a connecting wire and a connector, one side of the connector is arranged on the protection board of the battery assembly and electrically connected to the protection board, and the other side of the connector is electrically connected to the connecting wire.

[0036] This helps reduce defects caused by welding.

[0037] In some embodiments of the present application, the electronic device is a headset or a speaker.

[0038] Compared with the prior art, the embodiments of the present invention have the following beneficial effects: in the above-mentioned battery assembly and electronic device, the battery assembly includes a battery and a protection board; the battery has a first end face, and a first electrical connection contact and a second electrical connection contact are arranged on the first end face at intervals; on the one hand, the present application arranges the protection board close to the first end face and on the first electrical connection contact and the second electrical connection contact, and the protection board is electrically connected to the first electrical connection contact and the second electrical connection contact, respectively, which is beneficial to reducing the wire structure between the protection board and the battery, which is beneficial to improving the protection of the battery and reducing the clutter between the protection board and the battery; on the other hand, by setting the height of the first electrical connection contact from the first end face to be different from the height of the second electrical connection contact from the first end face, it is beneficial to reduce the risk of other metal structures contacting the positive and negative poles of the battery at the same time and causing a battery short circuit.

DETAILED DESCRIPTION

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0050] It should be understood that the terms "length", "width", "up", "down", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0051] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0052] It is important to know that with the rapid development of modern electronic devices, batteries, as key energy storage devices, are particularly important in various electronic devices for their stability and safety. Batteries not only provide the necessary power support for the device, but also directly affect the overall performance of the device and user experience. In order to ensure the stable operation of the battery in various usage environments, a protection board is usually set on the battery to monitor the working status of the battery and cut off the connection between the battery and other components in time under abnormal conditions (such as overcurrent, overheating, etc.), so as to prevent battery damage or safety accidents.

[0053] In the prior art, the connection between the protection board and the battery mainly relies on wires. Although this connection method meets the basic needs of battery protection to a certain extent, it has many shortcomings. First, when the battery has abnormal conditions such as overcurrent and overheating, the wires between the protection board and the battery are prone to leakage due to aging, wear or design defects of the wires themselves. Leakage may not only cause rapid consumption of battery power, but also cause serious consequences such as short circuits and fires, seriously threatening the overall safety of electronic equipment and the personal safety of users.

[0054] Secondly, the wire connection between the protection board and the battery increases the clutter of the device. As electronic devices are increasingly pursuing thinness and integration, too many wire connections not only take up valuable internal space, but also may affect the overall appearance and user experience of the device. In addition, the presence of wires also increases the difficulty of equipment assembly and maintenance, which is not conducive to improving production efficiency and reducing production costs.

[0055] Based on this, the present application improves the relevant battery components and electronic equipment.

[0056] See also Figure 1 , Figure 1 The schematic diagram of the structure of the battery assembly provided by the present embodiment is shown. The battery assembly of the present embodiment includes a battery 100 and a protection plate 200; the battery 100 has a first end face 110, and the first end face 110 is provided with a first electrical connection contact 120 and a second electrical connection contact 130 at intervals; the protection plate 200 is provided close to the first end face 110 and is provided on the first electrical connection contact 120 and the second electrical connection contact 130; the protection plate 200 is electrically connected to the first electrical connection contact 120 and the second electrical connection contact 130 respectively; wherein the battery assembly has a protection state, and in the protection state, the height of the first electrical connection contact 120 from the first end face 110 is different from the height of the second electrical connection contact 130 from the first end face 110.

[0057] It should be explained that the battery 100 may include batteries 100 of different structures such as cylindrical batteries 100 and square shell batteries 100. The battery 100 has two end faces arranged opposite to each other, and the first electrical connection contact 120 and the second electrical connection contact 130 are both arranged on the same end face (first end face 110). The first end face 110 is the main interface for connecting the battery 100 with the protective plate 200. The first electrical connection contact 120 and the second electrical connection contact 130 are convex structures on the first end face 110. The first electrical connection contact 120 and the second electrical connection contact 130 serve as the positive and negative electrodes of the battery 100, respectively. Exemplarily, the first electrical connection contact 120 is the positive electrode of the battery 100, and the second electrical connection contact 130 is the negative electrode of the battery 100. Alternatively, the first electrical connection contact 120 is the negative electrode of the battery 100, and the second electrical connection contact 130 is the positive electrode of the battery 100.

[0058] In the related art, the positive lead and the negative lead are directly drawn from the battery 100 in the battery assembly, and the positive lead and the negative lead are connected through the protective plate 200 to achieve a stable connection between the battery 100 and the protective plate 200. However, in the present application, on the one hand, the protective plate 200 is arranged close to the first end face 110, and is arranged on the first electrical connection contact 120 and the second electrical connection contact 130, and the protective plate 200 is electrically connected to the first electrical connection contact 120 and the second electrical connection contact 130 respectively, which is conducive to reducing the wire structure between the protective plate 200 and the battery 100, and is conducive to improving the protection of the battery 100 and reducing the degree of clutter between the protective plate 200 and the battery 100; on the other hand, by setting the height of the first electrical connection contact 120 from the first end face 110 to be different from the height of the second electrical connection contact 130 from the first end face 110, it is conducive to reducing the risk of other metal structures contacting the positive and negative electrodes of the battery 100 at the same time and causing the battery 100 to short-circuit.

[0059] In some embodiments of this application, please continue to refer to Figure 1 In this embodiment, in the protection state, the height of the first electrical connection contact 120 from the first end surface 110 is lower than the height of the second electrical connection contact 130 from the first end surface 110.

[0060] It is understandable that other metal shell structures will be preferentially connected to the second electrical connection contact 130 while maintaining a certain distance from the first electrical connection contact 120 , which is beneficial to avoid other metal shell structures being directly connected to the positive and negative electrodes of the battery 100 .

[0061] In some embodiments of this application, please refer to Figure 2 , Figure 2 A schematic structural diagram of a battery assembly provided in this embodiment is shown; an insulating structure 300 is provided between the first electrical connection contact 120 and the second electrical connection contact 130 in this embodiment.

[0062] It is understandable that the insulating structure 300 can isolate the first electrical connection contact 120 and the second electrical connection contact 130 , which is helpful to avoid short circuit between the first electrical connection contact 120 and the second electrical connection contact 130 , and further helps to avoid short circuit between the positive and negative electrodes of the battery 100 .

[0063] In some embodiments of this application, please refer to Figure 3 , Figure 3 The insulating structure 300 of this embodiment is arranged around the first electrical connection contact 120. It can be understood that this is conducive to improving the protection effect of the insulating structure 300 on the first electrical connection contact 120.

[0064] In some embodiments of this application, please refer to Figure 4 , Figure 4 A schematic diagram of the structure of the battery assembly provided in this embodiment is shown; the insulating structure 300 of this embodiment is a ring-shaped structure, the first electrical connection contact 120 is arranged inside the ring of the insulating structure 300, and the second electrical connection contact 130 is arranged outside the ring of the insulating structure 300.

[0065] It can be understood that the first electrical connection contact 120 and the second electrical connection contact 130 are completely separated, which is beneficial to optimize the isolation effect of the insulation structure 300 .

[0066] In some embodiments of this application, please continue to refer to Figure 2 In this embodiment, the insulating structure 300 is a silicone member, and the silicone member is disposed on the first end surface 110. It can be understood that starting from the first end surface 110, the insulating structure 300 can play an isolation effect between the first electrical connection contact 120 and the second electrical connection contact 130, which is conducive to improving the isolation effect of the insulating structure 300.

[0067] In some embodiments of this application, please continue to refer to Figure 2 , the height of the insulating structure 300 of this embodiment is higher than the height of the first electrical connection contact 120. It can be understood that since the insulating structure 300 is higher than the first electrical connection contact 120, the insulating structure 300 can protect the first electrical connection contact 120 in the height direction of the first electrical connection contact 120.

[0068] In some embodiments of this application, please continue to refer to Figure 2 In this embodiment, the first electrical connection contact 120 is the positive electrode of the battery 100 , and the second electrical connection contact 130 is the negative electrode of the battery 100 .

[0069] In some embodiments of this application, please continue to refer to Figure 2 In this embodiment, the second electrical connection contact 130 is a first elastic member, which connects the first end surface 110 and the protection plate 200 ; the height of the first elastic member from the first end surface 110 is higher than the height of the first electrical connection contact 120 from the first end surface 110 .

[0070] It is understandable that the first elastic member can first contact the first electrical connection contact 120 with the external conductive structure, which is beneficial to reduce the risk of the positive and negative electrodes of the battery 100 being simultaneously connected to the external conductive structure, thereby helping to avoid a short circuit between the positive and negative electrodes of the battery 100.

[0071] In some embodiments, the first elastic member is a spring.

[0072] In some embodiments of this application, please refer to Figure 5 , Figure 5A schematic diagram of the structure of the battery assembly provided in this embodiment is shown; the battery assembly also includes a second elastic member 400, and the battery assembly has a non-protected state. In the non-protected state, the second elastic member 400 connects the first electrical connection contact 120 and the protection plate 200; the sum of the height of the second elastic member 400 and the height of the first electrical connection contact 120 is equal to the height of the first elastic member.

[0073] It is understandable that when no protection is needed, the protection plate 200 and the positive and negative electrodes of the battery 100 can be connected through the second elastic member 400 and the first elastic member. When protection is needed, the second elastic member 400 can be removed.

[0074] In some embodiments, the second elastic member 400 is a spring.

[0075] In some embodiments of the present application, the first elastic member is configured such that, in a compressed state, the height of the first elastic member from the first end surface 110 is equal to the height of the first electrical connection contact 120 from the first end surface 110. It is understood that the protection plate 200 can be connected to the first elastic member and the first electrical connection contact 120 at the same time by compressing the first elastic member.

[0076] In some embodiments of this application, please refer to Figure 6 , Figure 6 A schematic diagram of the structure of the battery assembly provided in this embodiment is shown; the protection plate 200 of this embodiment has a second end face 210 arranged near the first end face 110, and the second end face 210 is provided with a first connecting portion 211 and a second connecting portion 212, and the second connecting portion 212 is arranged around the first connecting portion 211, the first connecting portion 211 is used to be electrically connected to the first electrical connection contact 120, and the second connecting portion 212 is used to be electrically connected to the second electrical connection contact 130.

[0077] It is understandable that even after the protection board 200 or the battery 100 is rotated by a certain angle, the second electrical connection contact 130 can still be connected to the second connection portion 212 , which is beneficial to ensure the connection stability between the battery 100 and the protection board 200 .

[0080] In some embodiments, the connecting wire 500 is selected from at least one of a positive line, a negative line, a ground line, and a detection line. Specifically, the detection line can be an NTC (Negative Temperature Coefficient Thermistor) detection line, which is used to detect the temperature of the protection board 200 to protect the protection board 200 and the battery 100 from over-temperature.
