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

[0034] The directional nouns involved in the embodiments of the present application, such as "upper", "lower", "side", etc., are generally represented by Figure 1 The relative relationship of the orientation shown in the figure is used as the basis, and these orientation terms are used only to more clearly describe the relationship between structures, not to describe absolute orientation.

[0035] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as those generally understood by those of ordinary skill in the art. Some technical terms appearing in the embodiments of the present application are explained below.

[0036] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0037] like Figures 1 to 3 As shown, an embodiment of the present application provides a battery 1, including a battery housing 11 and a battery cell assembly.

[0038] The battery housing 11 includes a first cover plate 111, a second cover plate 112 and an intermediate housing 113 arranged therebetween. The first cover plate 111, the second cover plate 112 and the intermediate housing 113 are arranged to form a cell accommodating cavity. The first cover plate 111 and the second cover plate 112 are respectively located on both sides of the width direction of the intermediate housing 113. The edges of the first cover plate 111 and the second cover plate 112 are both protruding relative to the outer peripheral wall of the intermediate housing 113 to form a flange edge 111a. The cell assembly is accommodated in the cell accommodating cavity.

[0039] Illustratively, the battery 1 provided in the embodiment of the present application is a steel shell battery, which has high strength, corrosion resistance and energy density.

[0040] Illustratively, the battery 1 provided in the embodiment of the present application is applied to an electronic device, and the electronic device is a mobile phone, a tablet computer, an e-reader, a laptop computer, an e-reader or a smart watch, etc. In this embodiment, only the electronic device being a mobile phone is used as an example for explanation.

[0041] The electronic device includes a middle frame 100, and the middle frame 100 is provided with a battery receiving slot 101 for accommodating a battery 1. Figures 1 to 3 As shown, the up-down direction in the figure is the length direction of the battery 1, the left-right direction is the width direction of the battery 1, and the front-back direction is the thickness direction of the battery 1. The length of the battery 1 is greater than the width of the battery 1. The battery housing 11 is accommodated in the battery receiving slot 101, and the battery 1 is used to power the electronic device.

[0042] The intermediate housing 113 has four sequentially connected side walls, and the first cover plate 111 and the second cover plate 112 respectively close the two openings in the width direction of the intermediate housing 113 to form a sealed cell accommodating chamber, and the cell assembly includes a diaphragm, an electrolyte, a cell, etc. Exemplarily, the first cover plate 111 and the second cover plate 112 are parallel to each other and are both perpendicular to the side walls of the intermediate housing 113.

[0043] In the prior art, the battery cover is usually arranged on both sides of the length direction of the battery. The flange edge of the cover affects the width of the battery, which has a greater impact on the loss of battery capacity. When the size of the battery receiving slot 101 remains unchanged, compared with the structural arrangement of arranging the first cover 111 and the second cover 112 on both sides of the length direction of the intermediate shell 113, the battery shell 11 provided in the embodiment of the present application can expand the size in the width direction, thereby improving the capacity and energy density of the battery 1.

[0044] Moreover, when the main board 200 and the sub-board 300 of the electronic device are respectively located on both sides of the length direction of the battery 1, the first cover plate 111 and the second cover plate 112 will not hinder the routing of the FPC (Flexible Printed Circuit) between the main board 200 and the sub-board 300, which is beneficial to improving the adaptability of the battery 1.

[0045] Exemplarily, the first cover plate 111 and the second cover plate 112 are connected to the intermediate shell 113 by welding, and the setting of the flange edge 111a provides a welding position for the first cover plate 111, the second cover plate 112 and the intermediate shell 113 to ensure the connection sealing and reliability of the battery shell 11.

[0046] The battery 1 provided in the embodiment of the present application reduces the space occupied by the first cover plate 111 and the second cover plate 112 in the width direction of the battery 1 while keeping the length, width and height dimensions of the battery 1 unchanged, thereby facilitating expansion of the width dimension of the battery casing 11, increasing the volume of the battery cell accommodating cavity, and thereby increasing the capacity of the battery 1.

[0047] In a further embodiment, the battery 1 also includes a battery protection board 14, which is covered on the first side of the intermediate shell 113 in the length direction and is electrically connected to the battery cell assembly, and the side of the battery protection board 14 facing away from the battery cell assembly is configured to be electrically connected to the mainboard 200 of the electronic device.

[0048] The battery protection board 14 is an integrated circuit board that protects the battery 1. Its working principle is to monitor the voltage, current, temperature and other parameters of the battery 1, and control the charging and discharging process of the battery 1 in real time to ensure that the battery 1 is in a safe working state. For example, when the voltage of the battery 1 is too high or too low, the battery protection board 14 will automatically cut off the charging and discharging of the battery 1 to prevent safety accidents caused by overcharging or over-discharging of the battery 1; for another example, when the temperature of the battery 1 is too high, the battery protection board 14 will also automatically cut off the charging and discharging of the battery 1 to prevent safety accidents caused by overheating of the battery 1.

[0049] like Figure 3 As shown, the upper side of the intermediate shell 113 is the first side in the length direction of the intermediate shell 113, and the battery protection plate 14 is located on the upper side of the intermediate shell 113. The battery protection plate 14 is arranged between the first cover plate 111 and the second cover plate 112, and is respectively perpendicular to the first cover plate 111 and the second cover plate 112. The thickness direction of the battery protection plate 14 is parallel to the length direction of the battery 1.

[0050] In a specific embodiment, the thickness of the battery protection plate 14 is less than or equal to the height of the flange edge 111a protruding relative to the outer peripheral wall of the intermediate shell 113 along the length direction of the intermediate shell 113. The thickness of the battery protection plate 14 can absorb the size of the flange edge 111a along the length direction of the battery 1, making full use of the space on the upper side of the intermediate shell 113, which is beneficial to increasing the capacity of the battery 1.

[0051] In a further embodiment, the battery 1 also includes a positive electrode column 12 and a negative electrode column 13, which are located on the first side of the length direction of the intermediate shell 113, and the ends of the positive electrode column 12 and the negative electrode column 13 facing away from the battery cell accommodating cavity are respectively connected to the battery protection board 14, and the ends of the positive electrode column 12 and the negative electrode column 13 facing the battery cell accommodating cavity are respectively electrically connected to the battery cell assembly.

[0052] like Figure 2As shown, the positive electrode column 12 and the negative electrode column 13 are spaced apart and distributed on one side of the length direction of the intermediate housing 113, and the battery protection plate 14 covers the top of the positive electrode column 12 and the negative electrode column 13 to achieve electrical contact connection with the positive electrode column 12 and the negative electrode column 13. Through this arrangement, the thickness of the battery protection plate 14 can absorb the size of the flange edge 111a along the length direction of the battery 1, which is conducive to improving the capacity of the battery 1.

[0053] Furthermore, if Figure 4 As shown, the distance between the surface of the battery protection plate 14 facing away from the intermediate housing 113 and the top wall of the intermediate housing 113 is D1, and the height of the flange edge 111a protruding relative to the top wall of the intermediate housing 113 in the length direction of the intermediate housing 113 is D2, satisfying:

[0054] D1≤D2.

[0055] Among them, Figures 1 to 3 As shown, the top wall of the intermediate shell 113 is the uppermost surface, and the surface of the battery protection board 14 facing away from the intermediate shell 113 is the upper surface of the battery protection board 14 .

[0056] like Figure 4 As shown, the upper surface of the battery protection plate 14 is lower than the upper edge of the flange 111a, that is, D1 is less than D2, so the thickness of the battery protection plate 14 and the height of the positive column 12 and the negative column 13 can absorb the size of the flange 111a along the length direction of the battery 1, and make full use of the space on the upper side of the intermediate shell 113. Alternatively, the upper surface of the battery protection plate 14 is flush with the upper edge of the flange 111a, that is, D1 is equal to D2, which can also absorb the size of the flange 111a along the length direction of the battery 1, which is beneficial to increase the capacity of the battery 1.

[0057] In a further embodiment, a positive electrode column mounting hole is opened on the first side surface of the intermediate shell 113 in the length direction, the positive electrode column 12 is inserted into the positive electrode column 12 mounting hole and connected to the battery cell assembly, and the negative electrode column 13 is installed on the surface of the first side in the length direction of the intermediate shell 113 and is adjacent to the positive electrode column 12.

[0058] In this embodiment, the battery case 11 is negatively charged, that is, the battery case 11 is connected to the negative electrode of the battery cell assembly in the battery cell receiving cavity. The battery case 11 is non-insulated and is directly placed in the battery receiving slot 101 of the electronic device. The positive and negative electrodes are led out from the battery cell assembly and extend out from the positive electrode column mounting hole. The negative electrode column 13 is fixed to the intermediate shell 113 by bonding, welding, etc. and is electrically connected to the intermediate shell 113.

[0059] like Figure 5 As shown, an embodiment of the present application further provides an electronic device, comprising the battery 1 provided in any of the above embodiments.

[0060] Electronic devices include mobile phones, tablets, e-readers, laptops, e-readers or smart watches, etc.

[0061] In a further embodiment, the electronic device further includes a middle frame 100 , and the middle frame 100 is provided with a battery receiving slot 101 for accommodating the battery 1 .

[0062] Exemplarily, the length direction of the middle frame 100 and the length direction of the battery receiving groove 101 are both parallel to the length direction of the battery 1, the width direction of the middle frame 100 and the width direction of the battery receiving groove 101 are both parallel to the width direction of the battery 1, and the shape and size of the battery receiving groove 101 are adapted to the shape and size of the battery 1.

[0063] In a further embodiment, the battery receiving groove 101 includes a first groove body 101a, a second groove body 101c and an intermediate groove body 101b which are interconnected. The first groove body 101a and the second groove body 101c are respectively located on both sides of the intermediate groove body 101b. The bottom wall of the intermediate groove body 101b abuts against the intermediate shell 113, and the first groove body 101a and the second groove body 101c are recessed relative to the bottom wall of the intermediate groove body 101b.

[0064] Specifically, the first tank body 101a and the second tank body 101c are respectively located on both sides of the width direction of the middle tank body 101b, the first tank body 101a is used to accommodate the first cover plate 111, the second tank body 101c is used to accommodate the second cover plate 112, and the middle tank body 101b is used to accommodate the middle shell 113. It can be understood that the length direction and width direction of the middle tank body 101b are respectively parallel to the length direction and width direction of the battery 1.

[0065] like Figure 6 As shown, the first trough body 101a and the second trough body 101c are both recessed relative to the bottom wall of the middle trough body 101b to accommodate the flange edge 111a and enable the middle shell 113 to fit the bottom wall of the middle trough body 101b, thereby increasing the contact area between the middle shell 113 and the middle trough body 101b, thereby stably placing the battery 1.

[0066] Furthermore, the electronic device also includes a main board 200 , a sub-board 300 and a connector 700 . The main board 200 and the sub-board 300 are respectively located on both sides of the length direction of the battery 1 , and the main board 200 and the sub-board 300 are electrically connected through the connector 700 .

[0067] like Figure 5As shown, the main board 200 is located above the battery 1, and the sub-board 300 is located below the battery 1. Exemplarily, the connector 700 is an FPC, and the connector 700 extends along the length direction of the middle frame 100. One end of the connector 700 is electrically connected to the main board 200 through the first connector 400, and the other end is electrically connected to the sub-board 300 through the second connector 500. The connector 700 is used to realize the electrical connection between the main board 200 and the sub-board 300.

[0068] In this embodiment, since the first cover plate 111 and the second cover plate 112 are arranged on both sides of the battery 1 in the width direction, the first cover plate 111 and the second cover plate 112 will not interfere with the connector 700 to affect the wiring arrangement of the connector 700, thereby improving the adaptability of the battery 1.

[0069] In a further embodiment, a mounting groove 102 is recessed on the bottom wall of the middle tank body 101 b . The mounting groove 102 extends along the length direction of the battery 1 , and the connector 700 is received in the mounting groove 102 .

[0070] like Figure 6 As shown, the mounting groove 102 is recessed downward relative to the bottom wall of the middle tank body 101b, so that the bottom wall of the mounting groove 102 is located below the bottom wall of the middle tank body 101b, and the mounting groove 102 is used to accommodate the connector 700. It can be understood that the length direction of the mounting groove 102 is parallel to the length direction of the battery 1, and the connector 700 is buried on one side of the thickness direction of the battery 1 through the mounting groove 102, which reduces the occupation of the battery 1 expansion space by the connector 700, improves the space utilization of the center frame 100, and facilitates the adaptation of the battery 1 to other components of the electronic device.

[0071] In a further embodiment, the battery 1 includes a battery protection board 14 , which is covered on one side of the intermediate shell 113 in the length direction and is electrically connected to the battery cell assembly, and the side of the battery protection board 14 facing away from the battery cell assembly is electrically connected to the main board 200 .

[0072] Specifically, the battery protection board 14 is located on the side of the battery close to the main board 200, and the battery protection board 14 is connected to the main board 200 through the battery connector 600 to achieve electrical connection between the battery protection board 14 and the main board 200. The thickness of the battery protection board 14 can absorb the size of the flange edge 111a along the length direction of the battery 1, which is conducive to improving the capacity of the battery 1.

[0073] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.
