[0042] Figure 1 is a schematic diagram of a battery according to an exemplary embodiment. Figure 1 As shown, the battery 100 includes:

[0043] A battery housing 1 and a battery cell 2, wherein the battery housing 1 has a receiving cavity 11a, and the battery cell 2 is located in the receiving cavity 11a;

[0044] A fixing portion 3 is provided on the side of the battery housing 1 , and the fixing portion 3 is used to fix the battery 100 to the side wall of the middle frame, wherein the side wall is the side wall opposite to the side edge.

[0045] In the embodiment of the present disclosure, the shape of the battery 100 can be a cuboid, a column, etc. The battery 100 includes a battery housing 1 and a battery cell 2. The battery cell 2 is used to store and release electrical energy; the battery housing 1 is used to wrap and protect the battery cell 2. In the embodiment of the present disclosure, the material of the battery cell 2 can be lithium ion, nickel metal hydride, lead acid, etc.; the shape of the battery cell 2 can be a column, a cuboid, etc.; the number of the battery cells 2 can be one or more. In the case of multiple battery cells 2, the battery cells 2 can be connected in series or in parallel.

[0046] In the disclosed embodiment, the battery housing 1 is provided with a receiving cavity 11a, and the aforementioned one or more battery cells 2 can be received in the receiving cavity 11a of the battery housing 1, wherein the shape of the receiving cavity 11a can be adapted to the shape of the battery cell 2, for example, when the battery 100 is provided as a single battery cell 2, the shape of the receiving cavity 11a is adapted to the shape of the single battery cell 2; for another example, when the battery 100 is provided as a battery cell 2 assembly composed of a plurality of battery cells 2, the shape of the receiving cavity 11a is adapted to the shape of the battery cell 2 assembly. In the disclosed embodiment, the battery housing 1 can be a cuboid, a cylinder, etc.; the battery housing 1 can be made of metal material, plastic material, etc., such as a steel shell battery 100 made of steel.

[0047] In the disclosed embodiment, the middle frame may be made of metal, plastic or composite materials, and may be used to fix the internal components of the electronic device, such as the screen, back cover, battery 100 and the like. Figure 2 is a schematic diagram of an electronic device according to an exemplary embodiment. Figure 2 As shown, the electronic device 1000 includes a middle frame 200 , and the battery 100 can be fixed in the middle frame 200 of the electronic device 1000 . The battery 100 is used to provide power for the electronic device 1000 .

[0048] In the embodiment of the present disclosure, the fixing portion 3 can be a variety of types such as an opening, a groove, a protrusion, etc., such as a fixing hole, a fixing groove, a protrusion, etc.; the shape of the fixing portion 3 can be a cuboid, a column, etc. In the embodiment of the present disclosure, the material of the fixing portion 3 can be the same as the material of the battery housing 1; or it can be different from the material of the battery housing 1. In some embodiments, the fixing portion 3 and the battery housing 1 are set to the same material, and the fixing portion 3 can be a structure integrally formed with the battery housing 1, for example, the battery housing 1 extends and bends toward the side to form the fixing portion 3 (such as a fixing hole); for another example, the battery housing 1 protrudes toward the side to form the fixing portion 3 (such as a protrusion). In other embodiments, the fixing portion 3 and the battery 100 can be set to different materials, and the fixing portion 3 and the battery housing 1 can adopt a split structure. The fixing portion 3 is set on the side of the battery housing 1 by means of colloid bonding, screw fixing, etc. For example, an L-shaped lock ear (fixing portion 3) is fixed on the large surface of the battery housing 1, so that the lock ear is located on the side of the battery housing 1.

[0049] In the disclosed embodiment, there are multiple ways to set the fixing part 3 on the side of the battery housing 1. The fixing part 3 may be set on one side of the battery housing 1; or the fixing part 3 may be set on multiple sides of the battery housing 1. The number of fixing parts 3 set on one side of the battery housing 1 may be one or more; the types of fixing parts 3 set on different sides may be the same or different. Figure 1As shown, a plurality of opening-type fixing portions 3 (fixing holes) are provided on one side of the rectangular parallelepiped battery 100 , and a protrusion-type fixing portion 3 (protrusion) is provided on the other side.

[0050] In the embodiment of the present disclosure, the side edge of the battery housing 1 and the side wall of the middle frame 200 are arranged opposite to each other. Figure 2 As shown, the side of the battery housing 1 is arranged parallel to the side wall of the middle frame 200. In the embodiment of the present disclosure, the battery 100 can be fixed to one or more side walls of the middle frame 200 by the fixing portion 3 on one or more side edges of the battery housing 1. There are many ways to fix the battery 100 to the side wall of the middle frame 200 by the fixing portion 3.

[0051] In some embodiments, the fixing part 3 is set as an opening type, and a corresponding through hole can be set on the side wall of the middle frame 200, and a plug-in connector that matches the opening shape of the fixing part 3 is inserted through the through hole on the middle frame 200 to plug the battery 100, so that the battery 100 is plugged and fixed to the side wall of the middle frame 200; in other embodiments, the fixing part 3 is set as a non-opening type (protrusion type or groove type), and the battery 100 can be clamped and fixed to the side wall of the middle frame 200 through the fixing part 3 on the side of the battery housing 1 and the clamping part (such as a groove or a protrusion) that matches the fixing part 3 set on the side wall of the middle frame 200. Among them, the plug-in connector and the clamping part can be the fixing parts used to install the battery 100 on the electronic device.

[0052] It should be noted that the fixing part 3 is usually a three-dimensional component, and the length, width, radius and other dimensions of the fixing part 3 on the large surface are usually larger than the height of the fixing part 3. The fixing part 3 is arranged on the side of the battery housing 1 to reduce the area occupied by the fixing part 3 on the large surface of the battery 100. Figure 1 As shown, the fixing portion 3 is a nearly cylindrical body, the large surface of the fixing portion 3 is nearly circular, the radius of the fixing portion 3 is much larger than the height of the fixing portion 3, and the fixing portion 3 is arranged on the side of the battery 100, which reduces the area occupied by the fixing portion 3 on the large surface of the battery 100. It can be understood that by arranging the fixing portion 3 on the side of the battery housing 1, the large surface area of ​​the battery 100 can be reduced when the capacity of the battery 100 remains unchanged, or the capacity of the battery 100 can be increased when the size of the battery 100 remains unchanged.

[0053] In the related art, there are two major ways to fix the battery 100 to the electronic device. One fixing method is to set a locking ear (fixing part 3) on the large surface of the battery 100, and fix the battery 100 to the electronic device through the locking ear on the large surface of the battery 100. However, the setting of the locking ear on the large surface will limit the size of the battery 100 (for example, the length or width of the battery 100 is limited), which may reduce the capacity of the battery 100. Another fixing method is to directly use a colloid to stick the battery 100 to the inside of the electronic device, but this method of fixing the battery 100 is affected by the viscosity of the glue layer, and it is easy to have a high return rate of the electronic device due to the loose adhesion of the battery 100.

[0054] In the embodiment of the present disclosure, the battery 100 is provided with a fixing portion 3 on the side of the battery housing 1, so that the battery 100 can be fixed to the side wall of the middle frame 200 by using the fixing portion 3 on the side of the battery housing 1. On the one hand, by using the fixing portion 3 on the side of the battery housing 1 to fix the battery 100 to the side wall of the middle frame 200, the size of the large surface of the battery 100 occupied by the fixing portion 3 can be reduced. In the case of limited installation space in the electronic device, the increase in the large surface area of ​​the battery 100 is conducive to increasing the capacity of the battery 100; on the other hand, by fixing the battery 100 to the side wall of the middle frame 200 by the fixing portion 3 on the side of the battery 100, compared with the method of only fixing the battery 100 by gluing, it is conducive to improving the stability of the installation of the battery 100.

[0055] In some embodiments, a first fixing portion 31 is provided on the first side 12a of the battery housing 1, and the first fixing portion 31 is used to fix the battery 100 to the first side wall 201a of the middle frame 200; and / or a second fixing portion 32 is provided on the second side 12b of the battery housing 1, and the second fixing portion 32 is used to fix the battery 100 to the second side wall 201b of the middle frame 200; wherein the first side 12a and the second side 12b are different, the first side wall 201a is a side wall opposite to the first side 12a, and the second side wall 201b is a side wall opposite to the second side 12b.

[0056] In the embodiment of the present disclosure, there are various types of the first fixing portion 31 on the first side 12a of the battery housing 1, which may be an open hole type (fixing holes of various shapes) or a non-open hole type (such as a groove, a protrusion, etc.), and the number of the first fixing portions 31 provided on the first side 12a may be one or more. In the case where there are multiple first fixing portions 31 on the first side 12a, the types of the first fixing portions 31 may be the same or different. As mentioned above Figure 1 As shown, three first fixing portions 31 (fixing holes) of the same type are provided on the first side 12a.

[0057] In the embodiment of the present disclosure, the first side wall 201a is arranged opposite to the first side edge 12a. There are multiple ways to fix the battery 100 on the first side wall 201a of the middle frame 200 by using the first fixing portion 31 of the first side edge 12a of the battery housing 1. In some embodiments, the first fixing portion 31 of the first side edge 12a is set to an opening type, and a corresponding through hole can be set on the first side wall 201a of the middle frame 200, and a plug-in component adapted to the opening shape of the first fixing portion 31 is used to pass through the middle frame 20 The through hole on the first side wall 201a is plugged with the battery 100, and the battery 100 is plugged and fixed to the first side wall 201a of the middle frame 200; in other embodiments, the first fixing portion 31 of the first side edge 12a is set to a non-opening type (a convex type or a groove type), and the battery 100 can be clamped and fixed to the first side wall 201a of the middle frame 200 by using a clamping member (such as a groove or a convex member) provided on the first side wall 201a of the middle frame 200 and matching the shape of the first fixing portion 31.

[0058] In the embodiment of the present disclosure, a second fixing portion 32 is provided on the second side 12b of the battery housing 1, and the second fixing portion 32 is used to fix the battery 100 on the second side wall 201b of the middle frame 200. For details, reference can be made to the related description of the first fixing portion 31, which will not be repeated in the present disclosure.

[0059] In the disclosed embodiment, the battery housing 1 may be provided with a fixing portion 3 on one side, or may be provided with the same or different types of fixing portions 3 on multiple different sides. In some embodiments, when the battery housing 1 is provided with multiple sides, the first side 12a and the second side 12b may be oppositely arranged sides, or may be non-opposite sides; the first fixing portion 32 provided on the first side 12a and the second fixing portion 32 provided on the second side 12b may be the same or different.

[0060] It should be noted that when the fixing part 3 (the first fixing part 31 or the second fixing part 32) is set to an opening type, fixing the battery 100 by plugging is beneficial to improving the stability of the fixation of the battery 100; when the fixing part 3 is set to a non-opening type, the snap-on method uses fewer components to complete the fixation of the battery 100, which is beneficial to the convenience of fixing the battery 100.

[0061] In the disclosed embodiment, the battery housing 1 can be flexibly provided with the same or different types of fixing parts 3 on one or more sides, thereby achieving a variety of fixing methods for the battery 100 and facilitating the firmness and convenience of fixing the battery 100 .

[0062] In some embodiments, the battery housing 1 includes a housing body 11 and a cover body 12;

[0063] The shell body 11 has the accommodating cavity 11a;

[0064] The cover 12 covers the accommodating cavity 11 a of the shell body 11 , and extends toward the first side edge 12 a of the shell body 11 and is bent to form a bent portion 12 c , and the bent portion 12 c is provided with the first fixing portion 31 .

[0065] In the embodiment of the present disclosure, the battery housing 1 includes a housing body 11 and a cover body 12. The housing body 11 and the cover body 12 can be arranged opposite to each other, and the shapes of the housing body 11 and the cover body 12 are adapted. Figure 1 As shown, the rectangular battery housing 1 includes a rectangular shell body 11 and a square cover body 12 which is not fully shown. The center point of the shell body 11 coincides with the center point of the cover body 12 .

[0066] In the disclosed embodiment, the shell body 11 of the battery shell 1 has a receiving cavity 11a, and the battery cell 2 can be arranged in the receiving cavity 11a of the shell body 11, and the cover body 12 of the battery shell 1 is covered on the receiving cavity 11a of the shell body 11, so that the shell body 11 and the cover body 12 form a closed space to enclose the battery cell 2 of the battery 100. The gap between the shell body 11 and the cover body 12 can be sealed by means of colloid bonding or welding.

[0067] In the disclosed embodiment, the cover 12 of the battery housing 1 extends toward the first side 12a of the shell body 11 and bends to form a bent portion 12c. The cover 12 may extend toward one side of the shell body 11 or may extend toward multiple sides of the shell body 11. The cover 12 may extend toward each side of the shell body 11 and bend to form one or more bent portions 12c. The first fixing portion 31 is disposed on the bent portion 12c. The first fixing portion 31 of an open hole type or a non-open hole type may be disposed on the bent portion 12c. As described above Figure 1 As shown, the cover body 12 extends and bends toward two oppositely disposed side edges of the shell body 11 , and three bending portions 12 c are formed on the two side edges respectively, and each bending portion 12 c is provided with a hole-shaped first fixing portion 31 .

[0068] As mentioned above, the connector of the electronic device can be plugged into the fixing part 3 to fix the battery 100. If the operation is improper, for example, the connector is inserted too deep into the fixing part 3, it may cause deformation or even damage to the accommodating cavity 11a of the battery shell 1, thereby causing slight deformation or exposure of the battery cell 2.

[0069] In the disclosed embodiment, the first fixing portion 31 of the battery 100 is arranged on the bent portion 12c obtained by extending and bending the first side edge 12a of the battery 100 cover 12 toward the shell body 11, rather than directly arranging the first fixing portion 31 on the shell body 11 accommodating the battery cell 2. This can reduce the deformation or exposure of the battery cell 2 caused by improper fixing operation, and is beneficial to improving the safety of the battery 100.

[0070] In some embodiments, the cover body 12 extends along the first side edge 12a of the shell body 11 and is bent to form one or more bent portions 12c, and each bent portion 12c is provided with a first fixing portion 31 .

[0071] In the embodiment of the present disclosure, the cover body 12 extends along the first side 12a of the shell body 11. The first side 12a can be any side of the shell body 11. For example, the first side 12a can be the side with the longer side of the shell body 11, or the side with the shorter side of the shell body 11. In the embodiment of the present disclosure, the cover body 12 extends along the first side 12a of the shell body 11 and bends to form one or more bending portions 12c. When extending to form multiple bending portions 12c, the multiple bending portions 12c can be arranged at equal intervals or at non-equal intervals. A first fixing portion 31 is provided for each bending portion 12c.

[0072] As mentioned above Figure 1 As shown, three bends 12c are extended at equal intervals from the rectangular cover 12 along the length direction (first side 12a) of the shell body 11, and each bend 12c is provided with a first fixing portion 31. For example, the cover 12 of the battery 100 can be bent toward one side of the battery 100 to form three hole-shaped locking ears.

[0073] In the disclosed embodiment, the battery 100 extends and bends along the first side 12a of the shell body 11 through the cover body 12 to form a bent portion 12c where the first fixing portion 31 is set, which helps to reduce the use of materials of the battery shell 1 and facilitates lightweighting of the battery 100.

[0074] In some embodiments, the first fixing portion 31 is a first opening 31 on the bending portion 12 c.

[0075] In the disclosed embodiment, the first fixing portion 31 is a first opening 31 on the bent portion 12c, and the shape of the first opening 31 may be circular, square, etc. As mentioned above, the electronic device generally includes a fixing part for fixing the battery 100, such as a plug-in connector, a snap connector, etc., and the shape of the first opening 31 may be compatible with the shape of the fixing part used by the electronic device to fix the battery 100, so as to fix the battery 100 in the electronic device.

[0077] In some embodiments, the shell body 11 and the cover body 12 seal the accommodating cavity 11 a by welding.

[0078] In the disclosed embodiment, the shell body 11 and the cover body 12 of the battery shell 1 are welded to seal the accommodating cavity 11 a. The battery shell 1 is sealed by welding, which is easy to operate and has good sealing performance.

[0079] In some embodiments, the first side 12a and the second side 12b are sides that are perpendicular to each other.

[0080] In the embodiment of the present disclosure, the first side 12a and the second side 12b of the battery housing 1 are perpendicular sides, and the first fixing portion 31 on the first side 12a and the second fixing portion 32 on the second side 12b can be of the same type or different types.
