[0002] The battery pole is used to connect with electrical connectors such as metal sheets and wires, so that the battery is connected to other components in the circuit. In order to facilitate the connection between the battery and the electrical connector, the pole needs to protrude relative to the outer surface of the battery shell. Based on the current pole setting method, the space required for the battery in the prior art is relatively large, and the space required to be reserved for the battery in the electronic device is also correspondingly large.

[0027] Figure 1 and Figure 2A battery 100 in the prior art is shown, and the battery 100 includes a shell 101, a battery cell (not shown) and two poles 102. The shell 101 includes a cover plate 106 and a main shell 105. The main shell 105 can be made by a stamping process, and the main shell 105 and the cover plate 106 can be fixed to each other by welding. The outer edge of the cover plate 106 is arranged on the periphery of the main shell 105. The battery cell is located inside the shell 101, and the battery cell is electrically connected to the pole 102. For example, the battery cell includes a positive electrode ear and a negative electrode ear, and the two poles 102 are respectively a positive pole 103 and a negative pole 104, the positive pole ear is welded to the positive pole 103, and the negative pole ear is welded to the negative pole 104.

[0028] In the prior art, the space occupied by the battery 100 is relatively large. Figure 1 As shown, the pole 102 is arranged at the upper end of the main shell 105, and the pole 102 protrudes relative to the upper end surface of the main shell 105. Although the outer edge of the cover plate 106 may not protrude relative to the main shell 105 after the outer edge of the cover plate 106 is cut, the space occupied by the battery 100 in the up-down direction (i.e., the first direction) is still large due to the protrusion of the pole 102. If the pole 102 is changed to be arranged at the left end or the right end of the main shell 105, the space occupied by the battery 100 in the left-right direction (i.e., the second direction) will also be large.

[0029] In order to reduce the space occupied by the battery 100 , the present invention adjusts the position of the pole 102 and fully utilizes the space at the corners of the housing 101 to accommodate the pole 102 .

[0030] Figures 3 to 8 FIG. 1 shows a battery 100 according to a first embodiment of the present invention. Figure 3 As shown, the battery 100 includes a shell 101, a battery cell (not shown) and a pole 102, which is a positive pole 103. Both the shell 101 and the pole 102 can be made of metal. The battery cell is contained inside the shell 101, and the battery cell is electrically connected to the pole 102. The shell 101 includes two first enclosure plates 107 and two second enclosure plates 108, the two first enclosure plates 107 are spaced along the first direction, and the two second enclosure plates 108 are spaced along the second direction. The first direction and the second direction intersect, and the intersection of these two directions means that the two directions are not parallel and do not overlap, and the angle between the two directions can be a right angle, an acute angle or an obtuse angle. In this embodiment, the first direction is the up-down direction, the second direction is the left-right direction, and the first direction and the second direction are perpendicular to each other. The shell 101 also includes a connecting plate 109, and the two ends of the connecting plate 109 are respectively connected to a first enclosure plate 107 and a second enclosure plate 108.

[0031] In this embodiment, the connecting plate 109 is in an outwardly convex arc shape, which is conducive to increasing the cavity 126 (such as Figure 7 As shown in the figure, the housing 101 can accommodate a larger battery cell, thereby facilitating the improvement of the energy density of the battery 100. Figure 3 As shown, the housing 101 also includes three transition plates 110, which are also convex arc-shaped, and the two ends of the transition plates 110 are also connected to a first enclosure plate 107 and a second enclosure plate 108 respectively. A connecting plate 109 and three transition plates 110 are equivalent to the four rounded corners of the housing 101. It should be noted that the pole 102 is not installed at the transition plate 110. The housing 101 is provided with rounded corners to disperse or reduce stress, and can also reduce the risk of scratching the user at the corners of the housing 101 and piercing other components of the electronic device.

[0032] like Figure 4 As shown, the shell 101 also includes two third enclosing plates 112 spaced apart in the third direction. Any two of the first direction, the second direction and the third direction are perpendicular to each other. In the present embodiment, the third direction is the front-rear direction. Furthermore, the first direction may be the length direction of the battery 100, the second direction may be the width direction of the battery 100, and the third direction may be the thickness direction of the battery 100. The first enclosing plate 107 is connected to a third enclosing plate 112 at both ends (front and rear ends) in the third direction, and the second enclosing plate 108 is connected to a third enclosing plate 112 at both ends (front and rear ends) in the third direction. In this way, the first enclosing plate 107, the second enclosing plate 108, the third enclosing plate 112, the connecting plate 109 and the transition plate 110 together enclose a cavity 126 that can accommodate a battery cell. The position of the cavity 126 can refer to Figure 7 .

[0033] like Figure 6 As shown, for a first enclosed plate 107, a connecting plate 109 and a second enclosed plate 108 connected to each other, the extended surface of the first enclosed plate 107, the extended surface of the second enclosed plate 108 and the connecting plate 109 together enclose a receiving space 117. Figure 6 The first extended surface 113 in the middle, the extended surface of the second enclosing plate 108 is Figure 6 The first extension surface 113 and the second extension surface 114 are both planes. Figure 6 For example, the first extension surface 113 may satisfy the following conditions: the first extension surface 113 is perpendicular to Figure 6 When the battery 100 is observed from a third direction (such as Figure 6 As shown in FIG. 1 ), starting from the intersection of the first enclosed plate 107 and the connecting plate 109, a tangent line of the first enclosed plate 107 or the connecting plate 109 is drawn in a direction away from the first enclosed plate 107. The tangent line is the first extended surface 113 at Figure 6The relationship between the second extension surface 114, the second enclosing plate 108 and the connecting plate 109 is similar to the relationship between the first extension surface 113, the first enclosing plate 107 and the connecting plate 109, and will not be repeated here.

[0034] Please combine Figure 5 and Figure 6 If the portion of the pole 102 exposed outside the housing 101 (i.e., the portion of the pole 102 located outside the cavity 126 ) is called the external connection portion 118 , then the external connection portion 118 protrudes relative to the connecting plate 109 , and the external connection portion 118 is located in the accommodating space 117 . Figure 5 The external connection portion 118 is actually a part of the positive electrode column 103. In the present invention, "the external connection portion 118 is located in the accommodating space 117" means that the external connection portion 118 does not extend out of the accommodating space 117. For example, there may be a gap between the surface of the external connection portion 118 and the first extension surface 113; or, the surface of the external connection portion 118 may be tangent to the first extension surface 113, or, the surface of the external connection portion 118 may partially overlap with the first extension surface 113. Similarly, the surface of the external connection portion 118 and the second extension surface 114 may be spaced apart, tangent to, or partially overlap. In the first embodiment, there is a gap between the external connection portion 118 and any extension surface.

[0035] In the prior art, the pole 102 is equivalent to being directly protruded on the first enclosure plate 107 or the second enclosure plate 108. However, for the battery 100 of the present invention, since the external connection portion 118 of the pole 102 is located in the accommodation space 117, the pole 102 does not protrude relative to the first enclosure plate 107 in the first direction, and the pole 102 does not protrude relative to the second enclosure plate 108 in the second direction (e.g., Figure 5 Therefore, compared with the prior art, the battery 100 as a whole occupies less space in the first direction and the second direction.

[0036] In the first embodiment, the battery 100 includes only one positive pole 103, and the battery 100 does not have a negative pole 104. The housing 101 directly serves as the negative pole of the battery 100. This electrode arrangement is similar to the electrode arrangement of the cylindrical battery 100. In other embodiments, the battery 100 may also include two poles 102.

[0037] For example, please refer to Figure 1 and Figure 2 In the prior art, the negative pole 104 is directly connected to the shell 101, and the height of the negative pole 104 is relatively low. The positive pole 103 is insulated from the shell 101, and the height of the positive pole 103 is relatively high. Figure 1 and Figure 2The battery 100 shown in FIG. 1 can reduce the space occupied by the battery 100 even if only the height of the positive electrode column 103 is reduced. Fig. 9 and Fig.10 , the negative electrode column 104 can still remain on the first enclosure plate 107, and the positive electrode column 103 is arranged in the accommodation space 117 at the corner of the shell 101, which can also reduce the space occupied by the battery 100 (compared to Figure 1 and Figure 2 for example).

[0038] For example, Fig.11 As shown, in the third embodiment, two poles 102 and two connecting plates 109 are provided, and the poles 102 and the connecting plates 109 are provided one by one. A receiving space 117 ( Fig.11 The two poles 102 are respectively arranged in two different accommodating spaces 117, that is, the two external connecting parts 118 are located in different accommodating spaces 117. Since both the positive pole 103 and the negative pole 104 are located in the accommodating space 117, compared with the second embodiment, the protruding distance of the negative pole 104 of the third embodiment relative to the first enclosure plate 107 is reduced, and the battery 100 of the third embodiment occupies a smaller space.

[0039] In the case where the battery 100 includes two poles 102, in the first direction, the two poles 102 may be located at the same end of the battery 100. Fig.11 As shown, the two poles 102 are both located at the top of the battery 100. Alternatively, in the second direction, the two poles 102 are located at the same end of the battery 100, for example, the two poles 102 are both located at the left end or the right end of the battery 100. This arrangement is conducive to reducing the structural complexity and processing difficulty of the battery 100.

[0040] In some embodiments, the first enclosure plate 107 and the second enclosure plate 108 are both flat, the first direction and the second direction are perpendicular to each other, the normal direction of the first enclosure plate 107 is the first direction, and the normal direction of the second enclosure plate 108 is the second direction. The first to seventh embodiments shown in the drawings of the present invention all meet the above conditions. Under the above arrangement, the shape complexity and processing difficulty of the housing 101 are relatively low.

[0041] like Figure 5As shown, in the first embodiment, the connecting plate 109 is in the shape of a convex arc, the first enclosing plate 107 and the second enclosing plate 108 are both in the shape of flat plates, and both ends of the connecting plate 109 are tangent to the first enclosing plate 107 and the second enclosing plate 108 respectively. The outer surface of the outer connecting portion 118 of the pole column 102 includes adjacent first plane 115 and second plane 116. The first extended plane 113 is parallel to the first plane 115, and the distance between the first extended plane 113 and the first plane 115 is A1, where 0 < A1 ≤ 0.5 mm. With the size of the accommodating space 117 unchanged, the larger A1 is, the smaller the volume of the outer connecting portion 118 is. Therefore, A1 not being greater than 0.5 mm enables the outer connecting portion 118 to have a sufficiently large volume, thus facilitating the processing and assembly of the pole column 102 and the electrical connection between the pole column 102 and external devices. Similarly, to prevent the outer connecting portion 118 from being too small, the second extended plane 114 is parallel to the second plane 116, and the distance between the second extended plane 114 and the second plane 116 is A2, where 0 < A2 ≤ 0.5 mm.

[0042] In some other embodiments not shown, to prevent the outer connecting portion 118 from being too small, the first extended plane 113 can coincide with the first plane 115, and the second extended plane 114 coincides with the second plane 116.

[0043] In addition, when the connecting plate 109 is in the shape of a convex arc, the radius of the connecting plate 109 is not less than 1 mm. Since both ends of the connecting plate 109 are tangent to the first enclosing plate 107 and the second enclosing plate 108 respectively, the smaller the radius of the connecting plate 109 is, the smaller the accommodating space 117 is. Also, since the outer connecting portion 118 cannot extend beyond the accommodating space 117, the smaller the accommodating space 117 is, the smaller the outer connecting portion 118 of the pole column 102 needs to be set. The radius of the connecting plate 109 not being less than 1 mm enables the outer connecting portion 118 to have a sufficiently large volume, thus facilitating the processing and assembly of the pole column 102 and the electrical connection between the pole column 102 and external devices.

[0044] In some embodiments (such as the first embodiment and the third embodiment), the battery 100 further includes an outer insulating member 111, and at least one pole column 102 is connected to an outer connecting member. For example, Fig.12 the shown outer connecting portion 118 is a part of the positive pole column 103, and the outer insulating member 111 is used to separate the outer connecting portion 118 of the positive pole column 103 and the connecting plate 109, so that the positive pole column 103 is not electrically connected to the housing 101. There may be no outer insulating member 111 between the negative pole column 104 and the corresponding connecting plate 109, and the negative pole column 104 is directly electrically connected to the housing 101. Of course, in some other embodiments not shown, an outer insulating member 111 may also be provided at the negative pole column 104, and the negative pole column 104 and the housing 101 may also be insulated from each other.

[0045] The following is an example to illustrate the assembly method between the outer insulating member 111, the pole column 102, and the connecting plate 109. As Figure 7 shown, in the first embodiment, the battery 100 further includes an inner insulating member 120 and a riveting block 119. The riveting block 119 is located in the cavity 126, the pole column 102 penetrates through the connecting plate 109, and the riveting block 119 and the pole column 102 are fixed to each other. The inner insulating member 120 is clamped by the inner surface of the connecting plate 109 and the riveting block 119, and the outer insulating member 111 is clamped by the outer surface of the connecting plate 109 and the outer connecting portion 118.

[0046] Please refer to Figure 5 and Figure 6 , the outer insulating member 111 is located in the accommodation space 117. Such a setting can reduce the protruding distance of the outer insulating member 111 relative to the first enclosing plate 107 and the second enclosing plate 108, thereby reducing the space occupied by the battery 100 in the first direction and the space occupied in the second direction. "The outer insulating member 111 is located in the accommodation space 117" means that the outer insulating member 111 does not extend beyond the accommodation space 117.

[0047] As Figure 5 shown, the outer surface of the outer insulating member 111 includes an adjacent third plane 123 and a fourth plane 124. The first extension surface 113 is parallel to the third plane 123, and the distance between the first extension surface 113 and the third plane 123 is B1, 0 < B1 ≤ 0.5 mm. When the size of the accommodation space 117 remains unchanged, the larger B1 is, the smaller the volume of the outer insulating member 111 is. Therefore, B1 not being greater than 0.5 mm enables the outer insulating member 111 to have a sufficiently large volume, thereby facilitating the processing and assembly of the insulating member. Similarly, in order to prevent the outer insulating member 111 from having too small a volume, the second extension surface 114 is parallel to the fourth plane 124, and the distance between the second extension surface 114 and the fourth plane 124 is B2, 0 < B2 ≤ 0.5 mm.

[0048] Of course, in order to ensure that the outer insulating member 111 does not extend beyond the accommodation space 117, in some other embodiments not shown, the first extension surface 113 may coincide with the third plane 123, and the second extension surface 114 coincides with the fourth plane 124.

[0049] As Figure 8 shown, in the first embodiment, the outer connecting portion 118 is located between two third enclosing plates 112. That is, in the third direction, the outer connecting portion 118 of the pole column 102 and the third enclosing plate 112 are spaced apart. This can reduce the protruding distance of the pole column 102 relative to the third enclosing plate 112, thereby reducing the space occupied by the battery 100 in the third direction. Similarly, as Figure 8As shown, the outer insulating member 111 is also located between the two third enclosure plates 112. That is, in the third direction, the outer insulating member 111 is spaced apart from the third enclosure plates 112. This can reduce the protruding distance of the outer insulating member 111 relative to the third enclosure plates 112, thereby reducing the space occupied by the battery 100 in the third direction.

[0050] The second embodiment and the third embodiment are introduced below.

[0051] like Fig. 9 and Fig.10 As shown, the housing 101 of the second embodiment includes a cover plate 106 and a main housing 105. The cover plate 106 serves as one of the third enclosure plates 112. The main housing 105 is integrally formed, and the main housing 105 includes the first enclosure plate 107, the second enclosure plate 108, the connecting plate 109, the transition plate 110 and another third enclosure plate 112. The main housing 105 and the cover plate 106 are welded to each other. After the welding of the two is completed, if the housing 101 is observed along the third direction, the outer edge of the cover plate 106 is set at the periphery of the main housing 105. After the welding of the main housing 105 and the cover plate 106 is completed, the cover plate 106 can be cut to reduce the size of the protruding portion of the cover plate 106 relative to the main housing 105, thereby reducing the space occupied by the battery 100. After the cover plate 106 is cut, its outer edge can overlap with the first enclosure plate 107 and the second enclosure plate 108 (as shown in the first embodiment). Alternatively, as shown in the third embodiment, after the cover plate 106 is cut, its outer edge is still protruding relative to the first enclosing plate 107 and the second enclosing plate 108, but the size of the protrusion becomes smaller.

[0052] For the convenience of description, the third enclosure plate 112 protruding outward relative to the main shell 105 is referred to as the outer convex plate 127 below. The cover plate 106 mentioned above is the outer convex plate 127. The outer convex plate 127 satisfies the following conditions: when viewed along the third direction, the first enclosure plate 107, the second enclosure plate 108 and the outer connecting portion 118 are all located within the outer edge of the outer convex plate 127. Fig.12 As shown, in the third embodiment, the outer convex plate 127 includes a first side 121 and a second side 122, the first side 121 is parallel to the first enclosure plate 107, the second side 122 is parallel to the second enclosure plate 108, the distance between an adjacent first side 121 and a first enclosure plate 107 is D1, 0<D1≤1mm, and the distance between an adjacent second side 122 and a second enclosure plate 108 is D2, 0<D2≤1mm. Since D1 and D2 meet the above conditions, the size of the outer convex part of the outer convex plate 127 is small, which is conducive to reducing the space occupied by the battery 100. In addition, since D1 and D2 are greater than 0, the risk of damaging the first enclosure plate 107 or the second enclosure plate 108 when cutting the outer convex plate 127 is low.

[0053] In addition, if Fig.14 As shown, in the third direction, the distance (i.e., D3) between the outer convex plate 127 and the outer connecting portion 118 is not less than 0.8 mm. This arrangement can prevent the outer connecting portion 118 of the pole 102 from contacting the outer convex plate 127 (especially the positive pole 103 needs to be insulated from the housing 101). In addition, this arrangement can prevent the distance between the outer connecting portion 118 and the outer convex plate 127 from being too small, thereby reducing the risk of damage to the pole 102 when the outer convex plate 127 is cut. Similarly, in the third direction, the outer insulating member 111 is spaced from the outer convex plate 127, thereby reducing the risk of damage to the pole 102 when the outer convex plate 127 is cut.

[0054] In the embodiments described above, the connecting plate 109 is in a convex arc shape, but the shape of the connecting plate 109 is not limited to the above shape. Fig.15 As shown in FIG. 1 , the connecting plate 109 is in the shape of an inwardly concave arc. Fig.16 As shown, the connecting plate 109, the first enclosing plate 107 and the second enclosing plate 108 are all flat plates, the angle between the connecting plate 109 and the first enclosing plate 107 is an obtuse angle, and the angle between the connecting plate 109 and the second enclosing plate 108 is also an obtuse angle. Fig.17 As shown, the connection plate 109 includes two connection units 125 connected in sequence, the connection units 125 are in the shape of a flat plate, and the angle between adjacent connection units 125 is a right angle. Fig.18 As shown, the connection plate 109 includes three connection units 125 connected in sequence, the connection units 125 are flat, and the angle between adjacent connection units 125 is an obtuse angle. The number of connection units 125 can also be greater than three. When the number of connection units 125 is greater than three, the angle between adjacent connection units 125 is an obtuse angle, which is exemplified one by one here. Figures 15 to 17 The connecting plate 109 shown can also form a receiving space 117 together with the first connecting surface and the second connecting surface, and Figures 15 to 17 The connecting plate 109 shown has a simple shape and low processing difficulty and cost.
