Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0040] Figure 1 is a schematic diagram of the structure of a battery assembly provided by an embodiment of the utility model, Figure 2 This is a schematic diagram of an exploded structure of a protection plate included in a battery assembly provided by an embodiment of the utility model. Figure 3 : is a schematic diagram of the assembly structure of a protection plate included in a battery assembly provided by an embodiment of the utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the battery assembly includes:

[0041] A battery body 1 and a protection plate 2 located on the top of the battery body 1 .

[0042] A first electronic device 3 and a second electronic device 4 are electrically connected on a surface of a protective plate 2 away from a battery body 1, wherein a size of the first electronic device 3 in a first direction (Z) is greater than a size of the second electronic device 4 in the first direction (Z), and the first direction (Z) intersects with a plane where the protective plate 2 is located.

[0043] At least two metal connectors 5 are connected to the protective plate 2, and the orthographic projection of at least one surface of the metal connector 5 on the plane where the protective plate 2 is located overlaps with the orthographic projection of at least one second electronic device 4 on the plane where the protective plate 2 is located, the first electronic device 3 is located between two adjacent metal connectors 5, and the battery body 1 is electrically connected to the protective plate 2 through the metal connector 5.

[0044] It can be seen from the above embodiments that in the embodiments of the utility model, since the first electronic device 3 and the second electronic device 4 are electrically connected on the surface of the protection plate 2 away from the battery body 1, the metal connector 5 is connected to the protection plate 2, and the orthographic projection of at least one surface of the metal connector 5 on the plane where the protection plate 2 is located overlaps with the orthographic projection of at least one second electronic device 4 on the plane where the protection plate 2 is located, the first electronic device 3, the second electronic device 4 and the metal connector 5 are all located on the surface of the protection plate 2 away from the battery body 1, so that the protection plate 2 is located between the metal connector 5 and the battery body 1, and the space between the protection plate 2 and the battery body 1 is not occupied. In addition, since the orthographic projection of at least one surface of the metal connector 5 on the plane where the protection plate 2 is located overlaps with the orthographic projection of at least one second electronic device 4 on the plane where the protection plate 2 is located, the first electronic device 3 is located between two adjacent metal connectors 5, so that the first electronic device 3, the second electronic device 4 and the metal connector 5 are arranged on the same plane, so that the metal connector 5 does not occupy the space between the protection plate 2 and the battery body 1. To sum up, through the battery assembly provided by the embodiment of the utility model, the space between the protection plate 2 and the battery body 1 can be left unoccupied while the volume of the battery assembly remains unchanged, so that the space occupied by the protection plate 2 is reduced, which is beneficial to the increase of the effective space of the battery body 1, thereby reducing the difficulty of subsequently improving the energy density of the battery.

[0045] Among them, in the above embodiments, the battery body 1 can be a single cell or a dual cell, the battery body 1 can be a cylindrical structure, a rectangular structure, or other shapes, which are not limited in the embodiments of the utility model. The battery body 1 has a top surface, a top seal can be connected to the top surface, a pole ear 11 is connected to the top seal, the protection plate 2 is in contact with the top surface, and the pole ear 11 and the protection plate 2 are electrically connected.

[0046] The first electronic device 3 and the second electronic device 4 disposed on the surface of the protection plate 2 away from the battery body 1 may include devices such as fuses, MOS tubes, comparators, capacitors, etc. Since the functions of the electronic devices are different, the structures and occupied volumes of the electronic devices are also different, so that the sizes of the electronic devices in the first direction (Z) are also different. In the embodiment of the utility model, the size of the first electronic device 3 in the first direction (Z) is set to be larger than the size of the second electronic device 4 in the first direction (Z).

[0047] Specifically, in some embodiments, the size of the first electronic device 3 in the first direction (Z) is greater than or equal to 0.6 mm, and the size of the second electronic device 4 in the first direction (Z) is less than or equal to 0.6 mm. In this way, when the size of the metal connector 5 in the first direction (Z) (the thickness of the metal connector 5) is less than 0.3 mm, the sum of the size of the second electronic device 4 in the first direction (Z) and the size of the metal connector 5 in the first direction (Z) can be less than or equal to the size of the first electronic device 3 in the first direction (Z), thereby making the metal connector 5 not occupy the size of the battery assembly in the first direction (Z).

[0048] In order to utilize the space occupied by the first electronic device 3 and the second electronic device 4 and to make electrical connections with the circuit board assembly, a metal connector 5 is provided in the embodiment of the utility model. The metal connector 5 can be connected to the protective plate 2 by welding. In some embodiments, the metal connector 5 is constructed of an aluminum block, a nickel block, or a copper-plated nickel block, which is not limited in the embodiment of the utility model. The number of metal connectors 5 is determined according to the number of cells included in the battery body 1. For example, when the battery body 1 is a single cell, the number of metal connections is two, and when the battery body 1 is a dual cell, the number of metal connections is four.

[0049] In addition, the orthographic projection of at least one surface of the metal connector 5 on the plane where the protective plate 2 is located overlaps with the orthographic projection of at least one second electronic device 4 on the plane where the protective plate 2 is located, that is, at least one second electronic device 4 is located inside the cavity surrounded by the metal connector 5, and the first electronic device 3 with a larger size in the first direction (Z) is located between adjacent metal connectors 5.

[0050] In addition, in the embodiment of the utility model, the protection plate 2 includes a printed circuit board 21 and a flexible circuit board 22; the flexible circuit board 22 is overlapped on the end of the printed circuit board 21 in the third direction (X), and a metal connector 5 is connected to the overlap position of the flexible circuit board 22 overlapped on the printed circuit board 21. Among them, the third direction (X) intersects with the first direction (Z), and the third direction (X) is consistent with the extension direction of the protection plate 2. In this way, a metal connector 5 is connected to the overlap position of the printed circuit board 21 by the flexible circuit board 22 overlapped, so that the connection part between the flexible circuit board 22 and the printed circuit board 21 can be hidden by the metal connector 5, and the connection strength between the flexible circuit board 22 and the printed circuit board 21 can be increased by the metal connector 5.

[0051] As for the structure of the metal connector 5 , the metal connector 5 may be U-shaped, L-shaped, or other structures with at least two specific connection surfaces, which is not limited in the embodiment of the present utility model.

[0052] In some embodiments, Figure 3 , Figure 4 and Figure 6 As shown, the metal connector 5 includes a first connecting plate 51, a second connecting plate 52 and a third connecting plate 53; the first connecting plate 51 is connected between the first connecting plate 51 and the second connecting plate 52, the first connecting plate 51 and the second connecting plate 52 extend in the first direction (Z), and the plane where the third connecting plate 53 is located intersects with the first direction (Z); the first connecting plate 51 and the second connecting plate 52 are connected to the protective plate 2, and the orthographic projection of the third connecting plate 53 on the plane where the protective plate 2 is located overlaps with the orthographic projection of at least one second electronic device 4 on the plane where the protective plate 2 is located.

[0053] In this embodiment, the first connecting plate 51, the second connecting plate 52 and the third connecting plate 53 form a concave structure, or in other words, the first connecting plate 51, the second connecting plate 52 and the third connecting plate 53 form a U-shaped plate structure. In this way, the cavity structure formed by the first connecting plate 51, the second connecting plate 52 and the third connecting plate 53 can accommodate the second electronic device 4, and the first connecting plate 51 and the second connecting plate 52 can provide welding points for the protection plate 2, and the third connecting plate 53 can provide connection points for the battery body 1. In addition, since the first connecting plate 51 is connected between the first connecting plate 51 and the second connecting plate 52, the first connecting plate 51 and the second connecting plate 52 extend in the first direction (Z), and the plane where the third connecting plate 53 is located intersects with the first direction (Z), the metal connector 5 has connecting surfaces with different orientations, and the frame structure formed by the first connecting plate 51, the second connecting plate 52 and the third connecting plate 53 is more conducive to covering the second electronic device 4, and the overall structure of the metal connector 5 is more compact.

[0054] Regarding the connection method between the first connecting plate 51, the second connecting plate 52 and the protective plate 2, in one possible implementation method, the end of the first connecting plate 51 facing the protective plate 2 and the end of the second connecting plate 52 facing the protective plate 2 are both connected to the surface of the protective plate 2 away from the battery body 1.

[0055] In this embodiment, since the end of the first connecting plate 51 facing the protection plate 2 and the end of the second connecting plate 52 facing the protection plate 2 are both connected to the surface of the protection plate 2 away from the battery body 1, the first electronic device 3, the second electronic device 4 and the metal connector 5 can be welded to the surface of the protection plate 2 away from the battery body 1 through the same process. In addition, since the end of the first connecting plate 51 facing the protection plate 2 and the end of the second connecting plate 52 facing the protection plate 2 are welded to the surface of the protection plate 2 away from the battery body 1, the surface of the first connecting plate 51, the second connecting plate 52 in contact with the protection plate 2 is only the area of ​​the end of the first connecting plate 51 facing the protection plate 2 and the area of ​​the end of the second connecting plate 52 facing the protection plate 2, thereby achieving the coplanar arrangement of the first electronic device 3, the second electronic device 4 and the metal connector 5 in the case of a small connection area between the first connecting plate 51, the second connecting plate 52 and the protection plate 2.

[0056] In another possible implementation, the end of the first connecting plate 51 facing the protective plate 2 is connected to the first side surface of the protective plate 2, and the end of the second connecting plate 52 facing the protective plate 2 is connected to the second side surface of the protective plate 2. The first side surface and the second side surface are two opposite sides of the protective plate 2, and the first side surface and the second side surface respectively intersect with the surface of the protective plate 2 away from the battery body 1.

[0057] In this embodiment, since the end of the first connecting plate 51 facing the protective plate 2 is connected to the first side surface of the protective plate 2, and the end of the second connecting plate 52 facing the protective plate 2 is connected to the second side surface of the protective plate 2, the first side surface and the second side surface are two opposite sides of the protective plate 2. Therefore, the metal connector 5 can not only cover the first electronic device 3, but also partially cover the protective plate 2, thereby avoiding the first electronic device 3, the second electronic device 4 being arranged on the same plane as the metal connector 5 and occupying the area occupied by the first electronic device 3 and the second electronic device 4 on the protective plate 2.

[0058] Furthermore, the size of the first connecting plate 51 in the second direction (Y) and the size of the second connecting plate 52 in the second direction (Y) are greater than or equal to 0.1 mm and less than or equal to 0.2 mm; wherein the second direction (Y) intersects with the first direction (Z), and the second direction (Y) intersects with the extension direction of the protection plate 2. In this way, the first electronic device 3, the second electronic device 4 and the metal connector 5 can be arranged on the same plane while the first connecting plate 51 and the second connecting plate 52 occupy a small area of ​​the protection plate 2.

[0059] It should also be noted that according to Figure 1 and Figure 3As 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 Z-axis direction, the second direction is defined as the Y-axis direction, and the third direction is defined as the X-axis direction. Further explanation, the definition of vertical in the specification should be understood as vertical within a 10% fluctuation of 90 degrees, that is, the angle between the first direction and the second direction defined as between 80 degrees and 90 degrees should be understood as vertical.

[0060] In some embodiments, Figure 4 and Figure 5 As shown, the end of the battery body 1 facing the protection plate 2 is provided with a pole ear 11; the battery body 1 is electrically connected to the metal connector 5 on the protection plate 5 through the pole ear 11; the pole ear 11 is connected to the surface of the third connection plate 53 away from the protection plate 2. In this way, a larger connection area can be provided between the pole ear 11 and the metal connector 5.

[0061] Optionally, when the pole lug 11 is connected to the surface of the third connecting plate 53 away from the protective plate 2, the pole lug 11 is bent to form a first bent portion and a second bent portion, the first bent portion is attached to the surface of the third connecting plate 53 away from the protective plate 2, and the second bent portion connects the battery body 1 and the first bent portion. In this way, the pole lug 11 can form an L-shaped structure, which is convenient for stacking between the battery body 1 and the protective plate 2, thereby helping to reduce the space between the battery body 1 and the protective plate 2.

[0062] In addition, if Figure 7 As shown, in some embodiments, the battery assembly includes at least two battery bodies 1 arranged in parallel, the battery body 1 has a top seal 6 bent toward its top wall surface 12 and a side seal 7 bent toward its side wall surface 13, and the intersection of the top seal 6 and the side seal 7 forms a folded corner 8 protruding from the top wall surface 12; an avoidance groove 23 is opened in the middle of the protective plate 2, and the folded corner 8 is located in the avoidance groove 23.

[0063] In this embodiment, in the embodiment of the utility model, since the battery body 1 has a top seal 6 bent toward its top wall surface 12 and a side seal 7 bent toward its side wall surface 13, the intersection of the top seal 6 and the side seal 7 forms a folded corner 8 protruding from the top wall surface 12, and the protective plate 2 is arranged on the side of the top seal 6 away from the top wall surface 12, and the plate surface of the protective plate 2 is arranged opposite to the side surface of the top cover, and an avoidance groove 23 is opened in the middle of the protective plate 2, and the folded corner 8 is located in the avoidance groove 23, so that the folded corner 8 can pass through the avoidance groove 23, so that the protective plate 2 can avoid the folded corner 8, and when the battery is packaged, for batteries of the same size, the folded corner 8 and the protective plate 2 can jointly occupy the space above the top wall surface 12, thereby reducing the influence of the folded corner 8 on the assembly of the protective plate 2, so that the effective space of the battery body 1 is increased. That is, in the embodiment of the utility model, the folded corner 8 can be adapted to the protective plate 2 arranged on the top wall surface 12, and the installation position of the protective plate 2 will not be raised due to the folded corner 8. 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.

[0064] Furthermore, the portion of the protective plate 2 on one side of the avoidance groove 23 in the second direction (Y) is a connecting section, and the connecting section protrudes from the main body of the protective plate 2. In this way, the degree of reduction in the size of the connecting section in the second direction (Y) caused by the avoidance groove 23 on the protective plate 2 can be reduced, thereby reducing the degree of reduction in the strength of the protective plate 21 caused by the avoidance groove 23 on the protective plate 2.

[0065] Furthermore, the number of metal connectors 5 matches the number of battery bodies 1 included in the battery. For example, if the battery body 1 has two tabs, the number of metal connectors 5 is twice the number of battery bodies 1. In other embodiments, the number of tabs of the battery body 1 may be greater than two, such as three tabs or four tabs, and the number of metal connectors 5 may be adaptively configured, that is, one metal connector 5 is connected to one tab. Specifically, since one battery body 1 has two tabs 11, one tab 11 is electrically connected to one metal connector 5, and therefore, when the number of metal connectors 5 is equal to twice the number of battery bodies 1 included in the battery, the electrical connection requirements of the battery assembly can be met.

[0066] It can be seen from the above embodiments that in the embodiments of the utility model, since the first electronic device 3 and the second electronic device 4 are electrically connected on the surface of the protection plate 2 away from the battery body 1, the metal connector 5 is connected to the protection plate 2, and the orthographic projection of at least one surface of the metal connector 5 on the plane where the protection plate 2 is located overlaps with the orthographic projection of at least one second electronic device 4 on the plane where the protection plate 2 is located, the first electronic device 3, the second electronic device 4 and the metal connector 5 are all located on the surface of the protection plate 2 away from the battery body 1, so that the protection plate 2 is located between the metal connector 5 and the battery body 1, and the space between the protection plate 2 and the battery body 1 is not occupied. In addition, since the orthographic projection of at least one surface of the metal connector 5 on the plane where the protection plate 2 is located overlaps with the orthographic projection of at least one second electronic device 4 on the plane where the protection plate 2 is located, the first electronic device 3 is located between two adjacent metal connectors 5, so that the first electronic device 3, the second electronic device 4 and the metal connector 5 are arranged on the same plane, so that the metal connector 5 does not occupy the space between the protection plate 2 and the battery body 1. To sum up, through the battery assembly provided by the embodiment of the utility model, the space between the protection plate 2 and the battery body 1 can be left unoccupied while the volume of the battery assembly remains unchanged, so that the space occupied by the protection plate 2 is reduced, which is beneficial to the increase of the effective space of the battery body 1, thereby reducing the difficulty of subsequently improving the energy density of the battery.

[0067] The embodiment of the utility model further provides an electronic terminal, which includes the battery assembly in any of the above embodiments, and the battery assembly is electrically connected to the main board of the electronic terminal through a connector. Specifically, the aforementioned connector can be a protective plate 2 led out through a flexible circuit board. The beneficial effects of the electronic terminal are consistent with the beneficial effects of the battery assembly in the above embodiments, and the embodiment of the utility model will not be repeated here.

[0068] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the utility model embodiments.

[0070] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or terminal device.
