The rear side of the middle frame 4 has a battery compartment 41 in which a battery assembly is mounted, the battery assembly being located within the battery compartment 41. Referring to fig. 1, the rear of the battery compartment 41 is opened, and the battery cover 2 is positioned at the rear side of the middle frame 4 and covers the battery compartment 41. Thereby, the battery assembly can be conveniently assembled in the battery compartment 41 and the position of the battery assembly can be stabilized.

Specifically, the bottom wall of the battery compartment 41 smoothly transitions between both sides of the curved display screen 1 in the width direction and both side walls of the battery compartment 41, respectively, to form a first arc-shaped portion 411. Alternatively, the first arc portion 411 may be a circular arc. Further, the first arc 411 may be a first rounded corner, i.e. the first arc 411 is tangential to the bottom wall of the battery compartment 41 and the first arc 411 is tangential to the side wall of the battery compartment 41. Simple structure and convenient processing.

Wherein, the bottom wall of the battery compartment 41 refers to the inner wall of the battery compartment 41 adjacent to the curved display screen 1. Referring to fig. 2, a rounded transition between the left side of the bottom wall of the battery compartment 41 and the left side wall of the battery compartment 41 forms a first arc-shaped portion 411, and a rounded transition between the right side of the bottom wall of the battery compartment 41 and the right side wall of the battery compartment 41 forms a first arc-shaped portion 411. Wherein, the two first arc-shaped portions 411 may correspond to the two curved surface portions one by one. Specifically, the first arc portion 411 on the left side may correspond to the curved surface portion on the left side, and the first arc portion 411 on the right side may correspond to the curved surface portion on the right side.

Therefore, the occupied height of the battery compartment 41 can be reduced through the first arc-shaped portion 411, the occupied space of the battery compartment 41 is reduced, the distance between the battery compartment 41 and the curved surface portion can be increased, the thickness of the middle frame 4 is increased, the structural strength of the middle frame 4 is improved, and the optimization of the internal space of the electronic device 100 is facilitated.

According to the electronic device 100 of the embodiment of the invention, the bottom wall of the battery compartment 41 is smoothly transited between the two sides of the curved display screen 1 in the width direction and the two side walls of the battery compartment 41 to form the first arc-shaped part 411 respectively, so that the thickness of the left and right edges of the battery compartment 41 can be reduced, the occupied height of the left and right edges of the battery compartment 41 can be reduced, the distance between the battery compartment 41 and the curved part can be increased, the thickness of the middle frame 4 is increased, the structural strength of the middle frame 4 is improved, the thickness of the electronic device 100 is reduced, the internal space of the electronic device 100 is optimized, and the internal layout of the electronic device 100 is more reasonable.

According to some embodiments of the present invention, a battery assembly includes a battery cell 31, a packaging film 32 wrapped around the battery cell 31, and a packaging case 33 wrapped around the packaging film 32. The front wall surface of the package case 33 smoothly transitions between two sides of the curved display screen 1 in the width direction and two side wall surfaces of the package case 33 to form a second arc-shaped portion 331, the rear wall surface of the package case 33 smoothly transitions between two sides of the curved display screen 1 in the width direction and two side wall surfaces of the package case 33 to form a third arc-shaped portion 332, and the arc length of the third arc-shaped portion 332 is smaller than the arc length of the second arc-shaped portion 331.

Specifically, the rounded transition between the left side of the front wall surface of the package case 33 and the left side wall surface of the package case 33 forms the second arc-shaped portion 331, and the rounded transition between the right side of the front wall surface of the package case 33 and the right side wall surface of the package case 33 forms the second arc-shaped portion 331. The third arc-shaped portion 332 is formed by smoothly transitioning between the left side of the rear wall surface of the package case 33 and the left side wall surface of the package case 33, and the third arc-shaped portion 332 is formed by smoothly transitioning between the right side of the rear wall surface of the package case 33 and the right side wall surface of the package case 33. The arc length of the third arc-shaped portion 332 is less than or equal to the arc length of the second arc-shaped portion 331. Preferably, the third arc-shaped portion 332 has an arc length smaller than that of the second arc-shaped portion 331

Therefore, the arc length of the second arc-shaped portion 331 is greater than or equal to the arc length of the third arc-shaped portion 332, so that the thickness of the left and right side edges of the battery assembly can be reduced, the occupied height of the left and right side edges of the battery assembly can be reduced, the battery assembly can adapt to the assembly of the arc-shaped screen, and in addition, the internal layout of the electronic device 100 can be optimized, so that the internal layout of the electronic device 100 is more reasonable.

According to some embodiments of the present invention, the second arc-shaped portion 331 and the first arc-shaped portion 411 are formed as circular arcs, and the second arc-shaped portion 331 and the first arc-shaped portion 411 are concentric arcs. Referring to fig. 1 and 2, the second arc portion 331 may be fitted on an inner surface of the first arc portion 411. Alternatively, the interval between the second arc-shaped portion 331 and the first arc-shaped portion 411 is smaller. Thereby, the utilization rate of the battery compartment 41 can be improved, and space waste can be avoided.

Alternatively, the second arc portion 331 may be formed as a second rounded corner, and the third arc portion 332 may be formed as a third rounded corner. The radius of the second rounded corner is greater than the radius of the third rounded corner. Wherein, the larger the radius of the second fillet, the smaller the occupation height of the battery assembly. Simple structure and convenient processing.

Alternatively, the packaging film 32 may be an aluminum plastic film or a steel plastic film.

According to some embodiments of the present invention, the packaging 33 is a PET plastic (i.e., a polyethylene terephthalate plastic). Wherein PET is an abbreviation for Polyethylene terephthalate. Therefore, the reliability of the battery assembly can be improved, the battery assembly can be integrated into a whole, and the assembly of the battery assembly is facilitated.

According to some embodiments of the present invention, the side seal is formed on the opposite side walls of the packaging film 32, in particular, the left and right side walls of the packaging film 32, whereby sealability of the battery assembly can be improved.

Specifically, the side seal is folded at least twice to form a hem, the front end of which is lower than the front side surface of the packaging film 32 to form the second arc 331 on the package 33. For example, in some embodiments of the invention, the side seal is folded twice to form a double-folded structure. For example, the side seal may be formed by bending the side seal upward once and then bending the side seal downward once. Therefore, the occupied height of the side sealing edges can be reduced, the arc length of the second arc-shaped portion 331 on the packaging shell 33 can be increased, and when the second arc-shaped portion 331 is formed into a second round angle, the radius of the second round angle can be increased, so that the heights of the two side edges of the battery assembly can be further reduced.

Referring to fig. 1 and 2, the hem may include: a first flange 321 and a second flange 322. The first flange 321 is formed by bending upwards a side edge, and the second flange 322 is formed by bending downwards a part of the first flange 321.

For example, the second flange 322 may be formed by bending a portion of the first flange 321 downward toward a direction approaching the side wall of the packaging film 32, and at this time, the second flange 322 is located at a side of the first flange 321 approaching the side wall of the packaging film 32. Thus, not only the height of the side seal can be reduced, but also the dimension of the side seal in the left-right direction can be reduced.

It will be appreciated that the second flange 322 may also be formed by bending a portion of the first flange 321 downwardly in a direction away from the side wall of the packaging film 32, where the second flange 322 is located on the side of the first flange 321 away from the side wall of the packaging film 32. Thereby, the height of the side seal can also be reduced.

According to some embodiments of the invention, the front end of the second flange 322 is lower or flush with the rear end of the second arc 331. Specifically, the front end of the second flange 322 may be lower than the rear end of the second arc 331, or the front end of the second flange 322 may be flush with the rear end of the second arc 331. Thereby, it is advantageous to increase the arc length of the second arc-shaped portion 331 on the pack case 33, so that the heights at both side edges of the battery pack can be reduced.

Optionally, the first and second flanges 321, 322 are parallel. For example, referring to fig. 2, the folds are generally formed in a U-shape with the opening facing downward. Thereby, the occupation space of the folded edge can be further reduced.

According to some embodiments of the invention, the first fold 321 is parallel to the side wall of the packaging film 32. Thereby, the occupation space of the folded edge can be reduced even further.

According to some further embodiments of the present invention, the electronic device 100 further comprises: protection board and flexible circuit board. The protection board includes a first surface and a second surface which are oppositely arranged in the thickness direction of the battery cell 31, the tab of the battery cell 31 is welded on the first surface, and the flexible circuit board is welded on the second surface. Therefore, through respectively welding the flexible circuit board and the lugs of the battery cell 31 on the first surface and the second surface of the protection plate, the flexible circuit board can be led out from the end part of the battery assembly, and the top edge sealing of the packaging film 32 is bypassed, so that the interference between the flexible circuit board and the top edge sealing of the packaging film 32 can be avoided.
