The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] At present, electronic devices on the market, such as mobile phones and laptops, use different batteries, and the batteries of different types of electronic devices cannot match each other. For example, mobile phone batteries can only match mobile phones, and laptop batteries can only match laptops. Due to the poor compatibility of batteries of different electronic devices, they cannot be used interchangeably. On the one hand, the R&D cost and manpower and material resources are greatly increased. On the other hand, when the battery of an electronic device is damaged, the user can only customize and replace the battery of the same type, which has high maintenance and replacement costs and poor user experience.

[0045] In view of this, the utility model provides a battery. By arranging a power connection component on the battery cell, an openable and closable power connection compartment is defined. The power connection end of the electrical equipment can be inserted into the power connection compartment to draw power from the battery cell. This can greatly improve the versatility of the battery among different types of electrical equipment, which is beneficial to reducing research and development costs and research and development manpower and material resources. In addition, when the battery of the electrical equipment needs to be replaced, the user can use the battery of other equipment to replace it conveniently, which is beneficial to reducing the user's use cost and improving the user's use experience.

[0046] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0047] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0048] In the description of the present invention, "plurality" means two or more.

[0049] In the description of the present invention, a first feature being “above” or “below” a second feature may include that the first and second features are directly in contact with each other, or may include that the first and second features are not in direct contact but are in contact with each other via another feature therebetween.

[0050] In the description of the present invention, a first feature “above”, “over” and “above” a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature.

[0051] Reference below Figure 1-Figure 9A battery 1 according to an embodiment of the present utility model is described. The battery 1 may include: a battery cell 11 and a power connection assembly 20. The battery cell 11 is arranged along a first direction (eg Figure 1 A pole lug 12 is provided at one end of the battery cell 11 (in the X direction shown in the figure). The extension direction of the pole lug 12 on the battery cell 11 can be set as required, and the first direction can be the direction in which the pole lug 12 extends from the battery cell 11. For example, when the battery 1 is in an upright position, the pole lug 12 can extend vertically upward on the top surface of the battery cell 11, and the first direction can be the vertical direction; or, the pole lug 12 can also extend in the horizontal direction on a side wall of the battery cell 11, in which case the first direction can be the horizontal direction. Optionally, there can be two pole lugs 12, one positive pole lug and one negative pole lug. The current is output from the battery cell 11 through the positive pole lug, and returns to the battery cell 11 from the negative pole lug through the electrical equipment, forming a loop to supply power to the electrical equipment. Therefore, the number of the conductive sheets 22 can match the pole lugs 12, and two pieces are provided, which are electrically connected to the positive pole lug and the negative pole lug respectively.

[0052] The power connection assembly 20 and the pole tab 12 are located at the same end of the battery cell 11. The power connection assembly 20 may include a protection plate 21, a shell assembly 230, and a conductive sheet 22. The protection plate 21 may be used to regulate the current transmission state of the battery. The shell assembly 230 defines a power connection compartment, which is used to match the power connection terminal of the electrical equipment. The protection plate 21 and the conductive sheet 22 are both in the power connection compartment. The conductive sheet 22 is provided on the protection plate 21 and is electrically connected to the pole tab 12. The shell assembly 230 may protect the protection plate 21, the conductive sheet 22, and the pole tab 12.

[0053] The power connection compartment can be opened and closed. When the battery 1 is idle, the power connection compartment is closed to protect the internal protection board, conductive sheet, pole ear and other components from the external environment, avoiding dust accumulation and dirt inside the protection board, and improving the service life of the protection board; effectively reducing the oxidation rate of the protection board components, avoiding poor performance, short circuit and other problems caused by oxidation of metal components.

[0054] When the battery is installed in the power-consuming device or when the battery 1 of the power-consuming device needs to be replaced, the power supply terminal of the power-consuming device can be plugged into the power supply compartment to obtain power. The operation is simple and convenient, and is not limited by the type of the power-consuming device. For example, the power-consuming device can be a mobile phone, and the power supply terminal can be a power supply plug. The battery 1 compartment of the mobile phone can have a power supply plug, and the power supply plug is inserted into the power supply compartment to obtain power. Alternatively, the power-consuming device can also be a laptop computer, and the battery 1 compartment of the laptop computer also has a power supply plug, and the power supply plug is inserted into the power supply compartment to obtain power.

[0055] The battery of this embodiment is provided with a power connection assembly 20 on the battery cell. The power connection assembly 20 defines an openable and closable power connection compartment, so that power connection terminals of different types of electrical equipment can be inserted into the power connection compartment to draw power from the battery. In this way, the versatility of the battery between different types of electrical equipment can be greatly improved, which is beneficial to reducing research and development costs and research and development manpower and material resources. In addition, when the battery of an electrical equipment needs to be replaced, the user can use the battery of other equipment to replace it, which is beneficial to reducing the user's use cost and improving the user's use experience. In addition, the structure of the power connection assembly 20 is relatively simple and easy to implement.

[0056] refer to Figures 1 to 4 In some embodiments, the protection plate 21 can be fixed to one end of the battery cell 11 where the pole ear 12 is provided by welding or bonding. The protection plate 21 can have a first side surface and a second side surface opposite to each other along a second direction. The second direction can be parallel to the thickness direction of the battery cell 11. For example, the second direction can be Figure 1 The Z direction in the diagram. The conductive sheet 22 is arranged on the first side surface, and the pole ear 12 extends from the second side surface to the first side surface and is electrically connected to the conductive sheet 22. For example, the pole ear 12 extends from the end surface of the battery cell 11 along the first direction and is located on the second side surface of the protective plate 21. The pole ear 12 is bent at least once from the edge of the protective plate 21 away from the battery cell 11, so that the bent portion of the pole ear 12 reaches the first side surface of the protective plate 21 and is connected to the conductive sheet 22 on the first side surface. The bent portion of the pole ear 12 can at least partially cover the conductive sheet 22 and be spot-welded and fixed to the conductive sheet 22. In this way, the contact area between the pole ear 12 and the conductive sheet 22 is large, the current carrying capacity can be improved, and the conductive effect is good; the protective plate 21 plays a protective and supporting role for the pole ear 12 and the conductive sheet 22, and improves the stability of the structure.

[0057] refer to Figure 3Further, the conductive sheet 22 may include a connecting portion 221 and a power connection portion 222, wherein the connecting portion 221 is arranged in close contact with the first side surface of the protective plate 21, and in a second direction perpendicular to the first direction, the connecting portion 221 may be provided with a first area 221a and a second area 221b side by side, the pole tab 12 covers the first area 221a, so that the first area 221a is electrically connected to the pole tab 12, and the power connection portion 222 is provided in the second area 221b, and the power connection portion 222 cooperates with the second area 221b to be connected to the power connection terminal of an external electrical device to supply power. For example, the power connection portion 222 and the second area 221b can clamp the power connection terminal of the electrical device to achieve a reliable connection with the power connection terminal. The connecting portion 221 of the conductive sheet 22 is divided into a first area 221a and a second area 221b, and the portion of the conductive sheet 22 connected to the pole tab 12 and the portion of the conductive sheet 22 connected to the power terminal are staggered to avoid direct contact between the power terminal and the pole tab 12, to avoid friction and damage between the pole tab 12 and the power terminal, thereby avoiding short circuit of the battery cell 1 and damaging the battery 1, thereby improving the safety of the device.

[0058] It is understandable that for different types of electrical equipment, the size and structure of the electrical terminals may be different. Therefore, the electrical connection portion 222 of the conductive sheet 22 may be elastic to improve the matching effect with the electrical terminals of different types of electrical equipment.

[0059] In some embodiments, the elasticity of the power connection portion 222 of the conductive sheet 22 may be brought about by the material of the conductive sheet 22. For example, the conductive sheet 22 may be a nickel sheet, which has good conductivity and can also undergo elastic deformation to adapt to the power connection terminals of various types of electrical equipment. Of course, the conductive sheet 22 may also be other metal materials with conductivity and elasticity, such as copper or beryllium bronze, etc., and the present application does not impose any restrictions on this.

[0060] refer to Figure 3 , Figure 8 and Fig. 9Furthermore, the elasticity of the power connection portion 222 may also be brought about by the structure of the power connection portion 222. The power connection portion 222 may include a first extension segment 222a and a second extension segment 222b. Along the first direction, the first extension segment 222a is connected to the second area 221b of the connecting portion 221 and is located on a side of the second area 221b close to the battery cell 11. The first extension segment 222a extends along the thickness direction of the battery cell 11 and is parallel to the thickness direction of the battery cell 11. One end of the second extension section 222b is connected to the first extension section 222a, and the other end extends away from the battery cell 11 along the first direction, and the distance between the second area 221b of the connecting portion 221 gradually decreases after the extension, that is, the second extension section 222b is inclined toward the second area 221b compared to the first direction. At this time, a space can be defined between the second extension section 222b and the connecting portion 221 for clamping and fixing the power terminal of the electrical equipment. One end of the second extension section 222b away from the first extension section 222a forms a power socket with the connecting portion 221, and the power socket is the position on the second extension section 222b with the smallest distance from the connecting portion 221.

[0061] In other words, the setting of the power connection part 222 can be regarded as the first extension section 222a first bending relative to the second area 221b of the connection part 221, and the bending angle of the first bending can be 90°, and then the second extension section 222b is bent toward the connection part 221 for the second time to form an approximately U-shaped power connection structure, and the second extension section 222b as one side arm of the U-shape is inclined toward the other side arm. When the battery 1 is needed, the power connection terminal of the electrical equipment is inserted into the space from the power connection socket, and the second extension section 222b is elastic and can expand in the direction away from the connection part 221 according to the size of the power connection terminal to match different types of electrical equipment. At the same time, during the power collection process, the second extension section 222b applies a force toward the connection part 221 to the docking terminal, clamping the connection part 221 to improve the stability of the structure.

[0062] Continue to refer Figure 3 , Figure 8 and Fig. 9According to some embodiments of the present invention, the power connection portion 222 may further include a third extension segment 222c, which is connected to the second extension segment 222b and is located at one end of the second extension segment 222b away from the first extension segment 222a, and the third extension segment 222c and the second extension segment 222b at least partially overlap to improve the elasticity of the power connection portion 222 at the second extension segment 222b. For example, the third extension segment 222c can be regarded as an arc-shaped protruding structure formed by bending one end of the second extension segment 222b away from the first extension segment 222a toward the connecting portion 221. On the one hand, when the power terminal is inserted into the space, the arc surface of the arc-shaped protruding structure contacts the power terminal, and the friction force is small, thereby avoiding damage to the power terminal. On the other hand, the arc-shaped protruding structure of the third extension segment 222c occupies part of the space of the power socket, so that the power socket can match the power terminal with a smaller thickness, thereby improving the compatibility of the battery 1 with the electrical device.

[0063] It can be understood that after being bent, the third extension section 222c can completely overlap with the second extension section 222b, and the third extension section 222c and the second extension section 222b form a V-shaped structure, so that the third extension section 222c also has elasticity, which improves the clamping effect on the power terminal and ensures the stability of the power supply process. Of course, after being bent, the third extension section 222c can also have only a partial structure overlap with the second extension section 222b, and a cavity can be formed in the arc-shaped protruding structure of the third extension section 222c to increase the radius of the arc-shaped protruding structure, thereby reducing the space of the power socket, so that the power socket can match the power terminal with a smaller thickness, thereby improving the compatibility of the battery 1 with the electrical equipment.

[0064] refer to Figure 1 and Figure 2 In some embodiments, the shell component 230 of the power connection component 20 may include: a shell body 23 and a switch component 24, the shell body 23 defines a power connection compartment along the first direction, and the power connection compartment is provided with a power connection port at one end away from the battery cell 11, and the power connection port is arranged opposite to the conductive sheet 22; the switch component 24 is provided at the power connection port and is movably connected to the shell body 23 to open or close the power connection port.

[0065] When the battery 1 is in use, the switch 24 is opened to expose the power port, and the power terminal is inserted from the power port of the shell body 23 to contact the conductive sheet 22 to obtain power. The structure is simple and the operation is convenient. The switch 24 is movably connected to the shell body 23. For example, the connection method can be that the switch 24 is slidably set at the power port, and the power port is opened or closed by reciprocating the switch 24. It can also be that the switch 24 is flipped and set at the power port, and the power port is opened or closed by rotating the switch 24. The specific setting method can be set according to needs, and this application does not limit this.

[0066] refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 Further, the shell body 23 may include: a frame body 231 and a blocking plate 232. In the direction away from the battery cell 11 along the first direction, the two ends of the frame body 231 are respectively provided with a first opening and a second opening. The first opening is located at the end of the frame body 231 facing the battery cell 11, and the second opening is located at the end of the frame body 231 facing away from the battery cell 11. The protection plate 21, the pole ear 12 and the conductive sheet 22 extend into the inner side of the frame body 231 from the first opening; the blocking plate 232 is embedded in the second opening to at least partially block the second opening, the electrical port is opened on the blocking plate 232, and the switch member 24 is movably connected to the blocking plate 232.

[0067] At this time, the above-mentioned power connection compartment is defined in the frame 231, and the power connection port is located at the second opening. When the battery 1 is in use, the switch 24 is turned on, the power connection terminal is inserted into the power connection port and connected to the conductive sheet 22, and the power is taken from the battery cell 11 through the tab 12, which has a simple structure and strong practicality.

[0068] Among them, the blocking plate 232 is arranged at the second opening, and its main function is to block the internal space in the power connection cabin, so that the conductive sheet 22 and the protection plate 21 are in a closed space when the battery 1 is idle, to prevent dust and other debris from contaminating the conductive sheet 22, thereby extending the service life of the battery 1. Therefore, when the blocking plate 232 is arranged, it can only partially block the second opening, as long as it ensures that the conductive sheet 22 is sealed and protected. Of course, the blocking plate 232 can also completely block the second opening to provide sealed protection for all devices in the frame 231.

[0069] The switch component 24 is movably connected to the blocking plate 232. For example, the connection method can be that the switch component 24 is slidably set on the blocking plate 232, and the power port is opened or closed by reciprocatingly toggling the switch component 24. Alternatively, the switch component 24 can be flipped and set on the blocking plate 232, and the power port is opened or closed by rotating the switch component 24. The specific setting method can be set according to needs, and this application does not impose any restrictions on this. The switch component 24 is used to block or open the power port. Since the switch component 24 is set, the protection plate 21 is prevented from contacting the external air environment when the battery is idle, and dust and dirt are avoided inside the protection plate, thereby improving the service life of the protection plate. At the same time, it can also effectively reduce the oxidation rate of the pole ear 12 and the conductive sheet 22 on the protection plate 21, and avoid problems such as poor conductivity and short circuit caused by oxidation of the pole ear 12 and the conductive sheet 22.

[0070] Continue to refer Figure 5Furthermore, along the thickness direction of the battery cell 11, an abutment structure 2311 is provided on the inner wall of the frame 231, and the abutment structure 2311 is arranged opposite to the first area 221a of the connecting portion 221 of the conductive sheet 22, and the connection between the pole ear 12 and the first area 221a is pressed, thereby improving the stability of the connection between the pole ear 12 and the first area 221a, and ensuring the position stability of the overall structure formed by the protection plate 21, the pole ear 23 and the conductive sheet 22, so that the current output from the battery cell 11 is stable and continuous.

[0071] The function of the abutment structure 2311 is to apply pressure to the connection between the pole tab 12 and the first region 221a, so that the pole tab 12 and the first region 221a are in close contact. For example, the abutment structure 2311 may include abutment ribs, and the abutment ribs extend from the abutment ribs opposite to the first region 221a to the first region 221a until the connection between the pole tab 12 and the first region 221a is abutted and pressed against the protective plate 21, thereby improving the stability of the structure.

[0072] Continue to refer Figure 5 Furthermore, a plurality of abutment ribs serving as the abutment structure 2311 may be provided, and the plurality of abutment ribs are arranged at intervals along a second direction perpendicular to the first direction. On the one hand, for the connection position between the pole ear 12 and the first region 221a, a plurality of abutment ribs are provided, and the fixing effect is better. For example, for the connection position between a pole ear 12 and the first region 221a, two abutment ribs may be provided, respectively pressing against the two ends of the pole ear 12 in the second direction, and the fixing effect is better. Of course, the number of abutment ribs may be designed and selected according to specific needs, and the present application does not impose any restrictions on this. On the other hand, the abutment ribs are arranged at intervals, and a heat dissipation gap is reserved to avoid overheating of the pole piece and the conductive sheet 22 when the battery 1 is in use, thereby improving the safety of the battery 1.

[0073] refer to Figure 5 and Figure 6 According to some embodiments of the utility model, the blocking plate 232 may include: a plate body 2321 and a fixed plate 2322, the plate body 2321 is adapted to the shape of the second opening, the power ports are all opened on the plate body 2321, the fixed plate 2322 is arranged on the side of the plate body 2321 facing the power connection cabin, the fixed plate 2322 extends along the first direction, there are at least two fixed plates 2322, at least two fixed plates 2322 are respectively located on both sides of the power port along the second direction, the fixed plate 2322 is inserted into the inner side of the frame 231 and connected to the frame 231, and the switch member 24 is pivotally connected to at least one of the plate body 2321 and the fixed plate 2322.

[0074] The fixing plates 2322 located on both sides of the power connection port extend along the first direction and align with the space of the power connection part 222, so as to facilitate the insertion of the power connection terminal into the space from the power connection port to obtain electricity. For one power connection port, at least two fixing plates 2322 are required to cooperate with the inner wall of the frame 231 to form a sealed space for sealing and protecting the conductive sheet 22. The battery cell 11 has two pole ears 12 and requires two power connection ports. The power connection terminals are respectively inserted into the two power connection ports and connected to the positive ear and negative ear of the battery cell 11. Therefore, the fixing plates 2322 can be set to 4 pieces, respectively located on both sides of the two power connection ports to improve the stability of the structure. In addition, when the blocking plate 232 is inserted into the frame 231 from the second opening for installation, the fixing plate 2322 extending along the first direction can also play a guiding role to facilitate the installation and fixation of the blocking plate 232, and the fixing plate 2322 can separate the area where the conductive sheet is located from other areas in the power connection cabin.

[0075] The switch member 24 is pivotally connected to at least one of the plate body 2321 and the fixed plate 2322 to open or close the power port in a flipping manner. For example, the switch member 24 can be pivotally connected to the plate body 2321, or the switch member 24 can be pivotally connected to the fixed plate 2322, or the switch member 24 can be pivotally connected to the plate body 2321 and the fixed plate 2322, or the switch member 24 can be pivotally connected to both fixed plates 2322 at the same time, all of which can cause the switch member 24 to flip, thereby opening or closing the power port.

[0076] refer to Figure 6 and Figure 7 Furthermore, a pivot groove 23221 may be provided on the fixing plate 2322, and a pivot shaft 241 may be provided on the switch member 24. The pivot shaft 241 may be rotatably provided in the pivot groove 23221. By flipping the switch member 24 and rotating it around the pivot shaft 241, the switch member 24 may open or close the power port. The structure is simple and the operation is convenient.

[0077] The pivot groove 23221 can extend along the thickness direction of the battery cell 11, and form a mounting opening with one side of the fixing plate 2322 in the thickness direction. The end of the pivot shaft 241 located in the pivot groove 23221 can be installed into the pivot groove 23221 from the mounting opening, with a simple structure and convenient installation. After the assembly is completed, the inner wall of the frame 231 blocks the mounting opening, and the pivot shaft 241 will not fall out of the pivot groove 23221.

[0078] refer to Figures 6 to 8The power connection assembly 20 may also include an elastic reset member 25. On the one hand, the elastic reset member 25 is used to provide a pre-tightening force for the switch member 24. When the power terminal is not inserted into the power connection port, the switch member 24 is blocked by the pre-tightening force to prevent dust and other debris from entering the power connection port and contaminating the battery 1. On the other hand, the elastic reset member 25 provides a reset force for the switch member 24. After the battery 1 is used, the power terminal is pulled out of the power connection port, and the elastic reset member 25 applies a reset force to the switch member 24, so that the switch member 24 automatically resets and blocks the power connection port. It is simple, convenient and practical. For example, the elastic reset member 25 can be a torsion spring, which can be sleeved on the pivot shaft 241, the first terminal of the torsion spring abuts against the inner wall of the switch member 24 facing the battery cell 11, the second terminal of the torsion spring abuts against the inner wall of the frame 231, and the first terminal and the second terminal are perpendicular to each other, so as to apply a pre-tightening force and a reset force to the switch member 24.

[0079] refer to Figure 1 , Figure 2 , Figure 8 and Fig. 9 In some embodiments, the battery 1 may further include an injection molded part 13, which is disposed at one end of the battery cell 11 where the pole ear 12 is disposed, and the injection molded part 13 at least covers the peripheral side of the power connection component 20 and the connection portion between the battery cell 11 and the power connection component 20. For example, the injection molded part 13 may cover the peripheral side of the outermost frame 231 of the power connection component 20, in which case the connection portion between the battery cell 11 and the power connection component 20 is completely located in the frame 231 and is also covered by the injection molded part 13, so that the entire power connection component 20 is fixedly mounted on the battery cell 11 by the injection molded part 13. It can be understood that the injection molded part 13 can also cover more areas. For example, the injection molded part 13 can cover one end of the battery cell 11 where the pole ear 12 is set. In the first direction, the length and height of the injection molded part 13 match the battery cell 11, thereby improving the aesthetics of the battery 1. Alternatively, after the injection molded part 13 covers one end of the battery cell 11 where the pole ear 12 is set, it continues to extend along the first direction away from the power connection component 20 to completely cover the battery cell 11, thereby forming a protective layer on the outside of the battery cell 11.

[0080] The use principle of the battery 1 of the utility model is:

[0081] When the battery 1 is needed, the power terminal of the external electrical device pushes open the switch 24, inserts the power port, and extends into the space formed by the power connection portion 222 of the conductive sheet 22. The second extension 222b of the conductive sheet 22 clamps the power terminal and is connected to the power terminal. The current is output from the battery cell 11 through the tab 12 and the conductive sheet 22 to the electrical device for power supply. After use, just pull out the power terminal, and under the action of the elastic reset member 25, the switch 24 automatically flips over and closes the power port.
