[0002] With the development of science and technology, the functions of electronic terminals are becoming more and more abundant, the performance is getting higher and higher, and the requirements for battery capacity and charging and discharging capabilities are also increasing accordingly. For example, dual-cell or multi-cell batteries are increasingly widely used, for example, dual-cell batteries are used in foldable screen mobile phones to increase the battery's power supply capacity.

[0003] However, in the production process of dual-cell batteries, since the part where the side seal and the top seal are connected protrudes from the top wall of the battery cell when the side seal of the battery cell is bent toward the side wall and fits with the side wall, there is a side seal protrusion at the battery cell splicing position of the dual-cell battery, which makes the side seal protrusion occupy the space on the top of the battery cell, thereby affecting the assembly of the battery protection plate. If the overall installation position is raised to avoid the aforementioned side seal protrusion, the effective utilization space of the battery cell will be greatly compressed, and the energy density of the battery cannot be improved.

[0045] like Figures 1 to 11 As shown, the battery includes:

[0046] At least two battery cell bodies 1 are arranged in parallel, the battery cell body 1 has a top sealing edge 2 bent toward its top wall surface 11 and a side sealing edge 3 bent toward its side wall surface 12, and the intersection of the top sealing edge 2 and the side sealing edge 3 forms a folded corner 4 protruding from the top wall surface 11;

[0047] The protection plate 5 is arranged on the side of the top sealing edge 2 away from the top wall surface 11, and the plate surface of the protection plate 5 is arranged opposite to the side of the top sealing edge. The protection plate 5 is provided with at least one avoidance groove 51, and two adjacent corners 4 are located in the avoidance groove 51 at their corresponding positions;

[0048] The reinforcing structure 6 forms a connecting section 55 connecting two adjacent sections of the plate body 56 when the avoiding groove 51 is constructed on the protection plate 5 , and the reinforcing structure 6 is arranged on the connecting section 55 .

[0049] In the embodiment of the utility model, since the battery body 1 has a top sealing edge 2 bent toward its top wall surface 11 and a side sealing edge 3 bent toward its side wall surface 12, the intersection of the top sealing edge 2 and the side sealing edge 3 forms a folded corner 4 protruding from the top wall surface 11, and the protective plate 5 is arranged on the side of the top sealing edge 2 away from the top wall surface 11, and the plate surface of the protective plate 5 is arranged opposite to the side of the top sealing edge, and the protective plate 5 is provided with at least one avoidance groove 51, and two adjacent folded corners 4 are located in the avoidance groove 51 at their corresponding positions, so that the folded corner 4 can pass through the avoidance groove 51, so that the protective plate 5 can avoid the folded corner 4, and when the battery is packaged, for batteries of the same size, the folded corner 4 and the protective plate 5 can jointly occupy the space above the top wall surface 11, thereby reducing the influence of the folded corner 4 on the assembly of the protective plate 5, so that the effective space of the battery body 1 is increased. That is, in the embodiment of the utility model, the folded corner 4 can be adapted to the protective plate 5 set on the top wall surface 11, and the installation position of the protective plate 5 will not be raised due to the folded corner 4. For batteries of the same size, the effective space of the battery body 1 can be increased, so that the power supply capacity of the battery is improved, which is beneficial to improve the energy density of the battery. At the same time, since the protective plate 5 is constructed with the avoidance groove 51 to form a connecting section 55 connecting two adjacent sections of the plate body 56, and the reinforcing structure 6 is set on the connecting section 55, the strength of the connecting section 55 can be improved by the reinforcing structure 6, so as to solve the problem of insufficient strength of the protective plate 5 caused by the avoidance groove 51 on the protective plate 5, thereby avoiding the problem of deformation and fracture of the protective plate 5 caused during the battery assembly process, and improving the battery yield.

[0050] In summary, in the battery provided in the embodiment of the utility model, not only can the energy density of the battery be improved by opening the avoidance groove 51 on the circuit board to avoid the folded corner 4, but also the strength of the protective plate 5 will not be reduced due to the opening of the avoidance groove 51 on the protective plate 5.

[0051] Among them, in the embodiment of the utility model, the battery body 1 can be a cylindrical structure, a rectangular structure, or other shapes. The battery can include two battery bodies 1 or multiple battery bodies 1, and the embodiment of the utility model does not limit this. Usually, it is necessary to seal the top wall surface 11 of the battery body 1 to form a top sealing edge 2, and to seal the side wall surface 12 of the battery body 1 to form a side sealing edge 3. The intersection of the top sealing edge 2 and the side sealing edge 3 forms interference, so that the intersection of the top sealing edge 2 and the side sealing edge 3 convexly extends to the corner 4 away from the top wall surface 11.

[0052] In order to avoid interference of the folded corner 4 with the installation of the protection plate 5, in the embodiment of the utility model, the protection plate 5 is provided with at least one avoidance groove 51, and two adjacent folded corners 4 are located in the avoidance grooves 51 at their corresponding positions, and the number of avoidance grooves 51 provided on the protection plate 5 is determined according to the number of battery cell bodies 1. For example, when the battery includes two battery cell bodies 1, there is one folded corner 4, and the number of avoidance grooves 51 is 1, and when the battery includes three battery cell bodies 1, there are two folded corners 4, and the number of avoidance grooves 51 is 2.

[0053] Since the avoidance groove 51 is provided in the middle of the protection plate 5, the overall strength of the protection plate 5 is reduced. Based on this, in the embodiment of the utility model, a reinforcing structure 6 is provided, so that the reinforcing structure 6 is located on the protection plate 5 to form a connecting section 55 connecting two adjacent sections of the plate body 56 when the avoidance groove 51 is constructed. It should be noted that the connecting section 55 is a connecting portion connecting two sections of the plate body 56, and the number of the connecting sections 55 is determined according to the number of the battery body 1. For example, in the case where the battery includes two battery bodies 1, there is one folding angle 4, then the number of the avoidance groove 51 is one, and the number of the connecting sections 55 is also one. If the battery includes three battery bodies 1, there are two folding angles 4, then the number of the avoidance grooves 51 is two, and the number of the connecting sections 55 is two. The reinforcing structure 6 can be a plate-like structure, or a frame-shaped structure such as a U-shaped or L-shaped structure, which is not limited in the embodiment of the utility model.

[0054] For the specific form of the reinforcement structure 6, such as Figures 4 to 6 As shown, in a possible implementation manner, the reinforcement structure 6 is a support sheet 61 , and the support sheet 61 covers the connecting section 55 .

[0055] It should be noted that, in this embodiment, since the reinforcing structure 6 is a support sheet 61, and the support sheet 61 covers the connecting section 55, the specific support sheet 61 on the connecting section 55 can be used as a strength reinforcement, and the overall strength of the protective plate 5 can be improved by the support sheet 61. And since the support sheet 61 covers the connecting section 55, the support sheet 61 only occupies the size of the top of the connecting section 55, and only the size of the support sheet 61 in the second direction (Z) occupies the space, so the size of the overall battery in the second direction (Z) will not be increased due to the provision of the support sheet 61.

[0056] like Figures 1 to 3 As shown, in another possible implementation, the battery has an intersecting first direction (X) and a second direction (Z); the reinforcing structure 6 is a reinforcing cover 62, and the reinforcing cover (62) includes at least one plate-like structure whose positive projection in the second direction (Z) overlaps with the positive projection of the connecting section 55 in the second direction (Z), wherein the first direction (X) is the extension direction of the protective plate 5, and the plane formed by the first direction (X) and the third direction (Y) is parallel to the plane where the protective plate (5) is located. In this way, since the reinforcing cover (62) includes at least one plate-like structure whose positive projection in the second direction (Z) overlaps with the positive projection of the connecting section 55 in the second direction (Z), the specific support sheet 61 on the connecting section 55 can be used as a strength reinforcement, and then the overall strength of the protective plate 5 can be improved by the support sheet 61, and then the strength loss caused by the avoidance groove 51 on the protective plate 5 can be compensated.

[0057] Furthermore, the reinforcing cover 62 has a first side plate 621 and a second side plate 622 opposite to each other along the first direction X, a top plate 623 located in the second direction (Z), and a third side plate 623 located in the third direction (Y), and the first side plate 623, the second side plate (622), the top plate 623 and the third side plate 623 form a cover-like structure with openings on both sides;

[0058] The end of the first side plate 623 in the second direction (Z) is connected to the surface of the protection plate 5 away from the top wall surface (11), the end of the second side plate 622 in the second direction (Z) is connected to the surface of the protection plate 5 away from the top wall surface (11), the orthographic projection of the top plate 623 in the second direction (Z) and the orthographic projection of the avoidance groove 51 in the second direction (Z) partially overlap, the orthographic projection of the third side plate 623 in the second direction (Z) and the orthographic projection of the connecting section 55 in the second direction (Z) partially overlap, and an avoidance cavity is formed between the top wall surface 11 and the top plate 623, and the corner 4 is located in the avoidance cavity.

[0059] In this embodiment, since the orthographic projection of the top plate 623 in the second direction (Z) and the orthographic projection of the avoidance groove 51 in the second direction (Z) partially overlap, the orthographic projection of the third side plate 623 in the second direction (Z) and the orthographic projection of the connecting section 55 in the second direction (Z) partially overlap, a avoidance cavity is formed between the top wall surface 11 and the top plate 623, and the corner 4 is located in the avoidance cavity. Therefore, a cover-like structure with openings on two sides is formed between the first side plate 621, the second side plate 622, the top plate 623 and the third side plate 624, thereby ensuring that the reinforced cover 62 forms an avoidance cavity of stable size, and the corner 4 can be located in the avoidance cavity, so that the strength loss caused by opening the avoidance groove 51 on the protective plate 5 is compensated by the reinforced cover 62. Furthermore, since the end of the first side plate 621 in the second direction (Z) is connected to the surface of the protective plate 5 away from the top wall surface 11, and the end of the second side plate 622 in the second direction (Z) is connected to the surface of the protective plate 5 away from the top wall surface 11, the portion of the reinforcement cover 62 connected to the protective plate 5 is only the end of the first side plate 621 in the second direction (Z) and the end of the second side plate 622 in the second direction (Z). Therefore, the space occupied by the reinforcement structure 6 on the protective plate 5 can be reduced, which is beneficial to the arrangement of the electronic components 7 on the protective plate 5.

[0060] It should be noted that according to Figure 1 Figure 2 As shown, in the embodiment of the utility model, the X-axis direction and the Z-axis direction intersect, the X-axis direction and the Y-axis direction intersect, and the Y-axis direction and the Z-axis direction intersect. For the convenience of explanation, the first direction is defined as the X-axis direction, the second direction is defined as the Z-axis direction, and the second direction is defined as the Y-axis direction. Further explanation, the definition of vertical in the specification should be understood as vertical when it fluctuates by 10% within 90 degrees, that is, the angle between the defined first direction and the second direction should be understood as vertical when it is between 80 degrees and 90 degrees.

[0061] In addition, in some embodiments, Figure 7 As shown, the battery may also include an electronic component 7 and a plastic package, the protective plate 5 includes a flexible circuit board and at least two circuit boards stacked on the flexible circuit board, and the flexible circuit board is arranged on the top wall surface 11; the electronic component 7 is arranged on the surface of the circuit board away from the flexible circuit board, and the plastic package covers the electronic component 7.

[0062] Since the electronic component 7 is arranged on the surface of the circuit board away from the flexible circuit board, and the plastic seal covers the electronic component 7, on the one hand, when the battery is packaged, in the direction from the top wall surface 11 to the top sealing edge 2, the electronic component 7 will not occupy the additional size of the battery, that is, when the battery is packaged, only the circuit board needs to be packaged, and the electronic component 7 is inside the circuit board. The electronic component 7 will not occupy the space on the surface of the circuit board, and will not occupy the size of the battery in the direction from the top wall surface 11 to the top sealing edge 2, so that when the battery is packaged, the size of the battery is further reduced. That is, by arranging the electronic component 7 inside the protective plate 5, when the battery is packaged, for batteries of the same size, the size of the battery body 1 can be increased, which is conducive to improving the power supply capacity of the battery. On the other hand, the electronic component 7 is injection molded by the plastic seal, so as to avoid the electronic component 7 and the connection line of the electronic component 7 being directly exposed to the air surface, improve the waterproof and moisture-proof performance of the electronic component 7, improve the reliability of the protective plate 5, strengthen the integrity of the electronic component 7, improve the mechanical properties such as resistance to external impact and vibration, and improve the heat dissipation capacity of the protective plate 5, which can meet the requirements of large current rapid charging and discharging. It should be noted that the plastic package may be coated on the electronic component 7 by special processes such as wafer packaging or plastic packaging.

[0063] In addition, in some embodiments, Figure 8 As shown, the battery can have a second direction (Z), and the protective plate 5 has a first surface 52 and a second surface 53 opposite to each other along the second direction; the first surface 52 is in contact with the top sealing edge 2, and a fixing groove 54 is provided on the second surface 53, and an electronic component 7 is embedded in the fixing groove 54, wherein the second direction (Z) is a direction intersecting with the plane where the protective plate 5 is located.

[0064] Since the electronic component 7 is embedded in the fixing groove 54, when the battery is packaged, the size of the battery occupied by the electronic component 7 is smaller in the direction from the top wall surface 11 to the top sealing edge 2, that is, when the battery is packaged, the size of the electronic component 7 is smaller, so for batteries of the same size, the size of the battery body 1 can be increased, thereby improving the energy density of the battery. That is, by providing the fixing groove 54 on the second surface 53 and embedding the electronic component 7 in the fixing groove 54, it is equivalent to that the fixing groove 54 can avoid the electronic component 7, so that the size of the battery occupied by the electronic component 7 is reduced, and the size of the battery body 1 can be increased, thereby increasing the energy density of the battery.

[0065] It should be noted that a plurality of fixing grooves 54 may be provided on the second surface 53 , and an electronic component 7 is embedded in each fixing groove 54 .

[0066] In addition, in some embodiments, Fig. 9 As shown, the battery may further include an injection molded part 8 ; the injection molded part 8 covers the protection plate 5 and the top sealing edge 2 .

[0067] Since the battery also includes an injection molded part 8, when the battery is packaged, the protection plate 5, the top sealing edge 2 and the folded corner 4 can be covered by the injection molded part 8, that is, by providing the injection molded part 8, it is beneficial to package the battery and ensure the flatness of the top space of the battery.

[0068] It should be noted that the injection molded part 8 can be injection molded glue.

[0069] In addition, in the embodiment of the present application, the battery may further include adhesive tape, which is attached to the outer surface of the injection molded part 8.

[0070] In addition, in the embodiment of the present application, the protection plate 5 may be a printed circuit board (PCB).

[0071] In addition, in some embodiments, the battery further includes a tear-off sticker and a handle; the tear-off sticker simultaneously covers at least three surfaces of the battery cell body 1; the portion of the tear-off sticker on the battery cell body 1 has at least two relatively arranged notches, and a handle is arranged in each notch.

[0072] It should be noted that, in this embodiment, the tear-off sticker not only has the function of fixing and insulating, but also because the portion of the tear-off sticker on the battery body 1 has at least two relatively arranged notches, each notch is provided with a handle, so the battery can be removed by the handle, which is convenient for the later disassembly and assembly of the battery.

[0073] In addition, in some embodiments, Fig.11 As shown, the battery has an intersecting first direction (X) and a third direction (Y); the dimension of the connecting section 55 in the third direction (Y) is d, wherein 1.7 mm ≤ d ≤ 2 mm, the first direction (X) is the extension direction of the protective plate 5, and the plane formed by the first direction (X) and the third direction (Y) is parallel to the plane where the protective plate 5 is located. In this way, while ensuring that the avoidance groove 51 can avoid the folding angle 4, the reduction in the strength of the protective plate 5 caused by the excessive size of the groove is minimized. In addition, in order to ensure that the dimension d of the connecting section 55 in the third direction (Y) is between 1.7 mm and 2 mm, the connecting section 55 can be made to protrude from the side portions of the two adjacent sections 56 of the protective plate 5 in the third direction (Y).

[0074] In the embodiment of the utility model, since the battery body 1 has a top sealing edge 2 bent toward its top wall surface 11 and a side sealing edge 3 bent toward its side wall surface 12, the intersection of the top sealing edge 2 and the side sealing edge 3 forms a folded corner 4 protruding from the top wall surface 11, and the protective plate 5 is arranged on the side of the top sealing edge 2 away from the top wall surface 11, and the plate surface of the protective plate 5 is arranged opposite to the side of the top sealing edge, and the protective plate 5 is provided with at least one avoidance groove 51, and two adjacent folded corners 4 are located in the avoidance groove 51 at their corresponding positions, so that the folded corner 4 can pass through the avoidance groove 51, so that the protective plate 5 successfully avoids the avoidance groove 51, and when the battery is packaged, for batteries of the same size, the folded corner 4 and the protective plate 5 can jointly occupy the space above the top wall surface 11, thereby reducing the influence of the folded corner 4 on the assembly of the protective plate 5, so that the effective space of the battery body 1 is increased. That is, in the embodiment of the utility model, the folded corner 4 can be adapted to the protective plate 5 set on the top wall surface 11, and the installation position of the protective plate 5 will not be raised due to the folded corner 4. For batteries of the same size, the effective space of the battery body 1 can be increased, so that the power supply capacity of the battery is improved, which is beneficial to improve the energy density of the battery.
