In addition, the fifth surface 131 has fewer parts, which is beneficial for the adhesive member 40 to directly adhere and fix the battery assembly 30 to the rear cover, and effectively improves the fixing efficiency of the battery assembly 30.

The first housing 12 (main housing) includes a bottom plate 123 and a side plate 124, one end of the side plate 124 is disposed around the bottom plate 123, and the side plate 124 is disposed perpendicular to the bottom plate 123.

In some embodiments, the bottom plate 123 and the side plate 124 are integrally formed, the cover plate 133 and the connecting plate 134 are integrally formed, and the connecting plate 134 and the side plate 124 are connected by a snap connection or a screw connection.

Referring to fig. 4, the battery assembly 30 includes a first battery cell 31, a protection plate 32, and a conductive member 33. Protection plate 32 sets up in the one end of first electric core 31 and is connected with first electric core 31 electricity, and the one end of electrically conductive piece 33 is connected with protection plate 32 electricity, and the other end of electrically conductive piece 33 is connected with mainboard subassembly 20 electricity, and first electric core 31 provides the electric energy to mainboard subassembly 20 through electrically conductive piece 33, and protection plate 32 then has the effect of guaranteeing first electric core 31's safety.

In some embodiments, referring to fig. 5, in a direction perpendicular to the third surface 121 of the main housing, since the thickness of the protection plate 32 is smaller than that of the first battery cell 31, one end of the first battery cell 31 connected with the protection plate 32 may be disposed between the bottom plate 123 of the main housing and the connection plate 134 of the rear cover, so as to improve the space utilization rate of the accommodating cavity 11.

Referring to fig. 4, the first cell 31 includes a first surface 311 and a second surface 312, which are disposed opposite to each other, where the first surface 311 and the second surface 312 are both the outer surfaces of the first cell 31 with the largest area, i.e., the body surfaces of the first cell 31. The adhesive member 40 includes a first adhesive member 41, the first adhesive member 41 is disposed between the first surface 311 of the first cell 31 and the third surface 121 of the main casing, and the first adhesive member 41 is used for adhering and fixing the first cell 31 to the main casing.

In some embodiments, the adhesive 40 is disposed between the body surface of the first cell 31 and the inner surface of the casing 10, and the plane in which the adhesive 40 is disposed is parallel to the first surface 311 or the second surface 312 of the first cell 31. In order to ensure the bonding firmness of the bonding member 40, the bonding area S1 of the bonding member 40 to the body surface of the first battery cell 31, and the area S2 of the body surface of the first battery cell 31 satisfy: 30% to S1/S2 to 100%, i.e., the area of the body surface of the first cell 31 covered by the adhesive member 40 needs to occupy more than about one third of the area of the body surface of the first cell 31.

It is understood that the first adhesive member 41 may be a conventional double-sided tape, or may be an easily detachable easy-open adhesive, and the adhesive member 40 is not limited in this application. The number of the adhesive members 40 may be one or more, and the number of the adhesive members 40 is not limited in the present application. The total weight G of the adhesive 40 satisfies: g is more than or equal to 0.5G and less than or equal to 4G, compared with the method of wrapping and fixing the first battery cell 31 by using a rubber frame and large-area adhesive paper, the method is more convenient to directly bond the first battery cell 31 to the inner surface of the shell 10 by using the bonding member 40, and the total weight of the bonding member 40 is lighter, so that the weight of the electronic device 100 can be greatly reduced.

The thickness H1 of the adhesive member 40 in the direction perpendicular to the inner surface of the case 10 satisfies: h1 is more than or equal to 0.05mm and less than or equal to 0.3mm. On the premise that the adhesive 40 can fix the first battery cell 31 to the casing 10, the thinner the thickness of the adhesive 40 is, the more the space of the accommodating cavity 11 is released. The bonding force F between the bonding member 40 and the first battery cell 31 satisfies: f is more than or equal to 1kgf/in and less than or equal to 3kgf/in.

In some embodiments, continuing to refer to fig. 1, battery assembly 30 further includes a bracket 34. The support 34 is disposed in the first mounting region 1212 of the third surface 121 of the main housing, and a surface of the support 34 facing the rear cover is flush with a surface of the protrusion 1211, so that the first bonding member 41 can bond the first surface 311 of the first battery cell 31 and the surface of the support 34 facing the rear cover, thereby increasing a bonding area of the first battery cell 31 and improving safety and stability of the first battery cell 31. On one hand, the bracket 34 is arranged, so that the problem that the battery assembly 30 is suspended can be effectively avoided, and abnormal sound generated by collision between the first battery cell 31 and the main case in the use process of the electronic device 100 is avoided; on the other hand, the third surface 121 can be filled by the bracket 34 and then forms a flush surface again, so that the regular single first battery cell 31 can be conveniently mounted without setting the regular multiple first battery cell 31, and the manufacturing cost of the first battery cell 31 is effectively reduced.

In some embodiments, a surface of the bracket 34 close to the first battery cell 31 is provided with a groove 341, and the groove 341 can greatly reduce the total weight of the bracket 34 without affecting the supporting function of the bracket 34. Of course, the bracket 34 may be provided with other hollow structures to reduce the weight of the bracket 34. In order to ensure the bonding firmness of the first bonding member 41, the area S3 of the first bonding member 41 bonded to the bracket 34, and the area S4 of one surface of the bracket 34 close to the first battery cell 31 satisfy: S3/S4 is more than or equal to 30 percent and less than or equal to 100 percent. That is, the area of the surface of the bracket 34 covered by the first adhesive member 41 needs to occupy more than about one third of the area of the surface of the bracket 34 close to the first battery cell 31.

In the embodiment of the present application, the first housing 12 (main housing) and the second housing 13 (back cover) are directly connected by a snap-fit manner, in some other embodiments, the bracket 34 may be provided with a snap-fit portion, and the bracket 34 is respectively snap-fit connected with the first housing 12 and the second housing 13, so as to connect the first housing 12 and the second housing 13.

In some embodiments, with continued reference to fig. 1, the battery assembly 30 further includes a first buffer member 35. The first buffer 35 may be a flexible material such as sponge or foam, and the first buffer 35 is disposed between the second surface 312 of the first battery cell 31 and the fifth surface 131 of the rear cover. The first buffer member 35 is configured to buffer an acting force, which acts on the rear cover from the outside in the use process of the electronic device 100, to cause pressure on the first battery cell 31, so as to affect performance of the first battery cell 31.

Of course, in some embodiments, referring to fig. 6, the battery assembly 30 further includes a second battery cell 37, wherein, along a direction perpendicular to the third surface 121 of the main housing, a thickness of the first battery cell 31 is smaller than a thickness of the second battery cell 37, the first battery cell 31 is fixed to a region of the protrusion 1211 on the third surface 121 by the first adhesive member 41, and the second battery cell 37 is fixed to the first mounting region 1212 of the third surface 121 by the first adhesive member 41, that is, the electronic device 100 may not be provided with the bracket 34 to fill a region of the third surface 121 except the protrusion 1211, but may be provided with the first battery cell 31 and the second battery cell 37 having different thicknesses to be directly filled, so that a space of the third surface 121 is effectively utilized, and the capacity of the first battery cell 31 is increased.

In the above embodiments, the first battery cell 31 is adhesively fixed to the main casing by the adhesive 40, and in other embodiments, the first battery cell 31 may be adhesively fixed to the rear cover by the adhesive 40. Referring to fig. 7 and 8, the adhesive member 40 includes a second adhesive member 42, and the second adhesive member 42 is disposed between the second surface 312 of the first cell 31 and the fifth surface 131 of the back cover, that is, the second adhesive member 42 adheres and fixes the first cell 31 to the back cover. Because the components on the back cover are fewer than the components on the main casing body, the difficulty of bonding and fixing the first battery cell 31 to the back cover through the second bonding piece 42 is less than the difficulty of bonding and fixing the first battery cell 31 to the main casing body through the first bonding piece 41.

In some embodiments, referring to fig. 11, in order to mount the first battery cell 31 on the back cover more quickly during the assembly process, a retaining wall 1331 is disposed on a surface of the cover plate 133 of the back cover facing the receiving cavity, the retaining wall 1331 and the cover plate 133 together enclose a battery placing area, the second adhesive member 42 is disposed between the battery placing area and the second surface of the first battery cell 31, and the second adhesive member 42 fixes the first battery cell 31 in the battery placing area. On one hand, the retaining wall 1331 has a marking function on the installation position of the first battery cell 31, and on the other hand, the retaining wall 1331 may have a limiting function on the first battery cell 31 installed in the battery placement region, so as to prevent the first battery cell 31 from moving relative to the rear cover by breaking away the constraint of the adhesive force of the second adhesive member 42 in an abnormal use state such as dropping or violent impact of the electronic device 100.

In some embodiments, the retaining walls 1331 are L-shaped, and two L-shaped retaining walls 1331 are disposed on the cover plate 133 along the diagonal of the second surface of the first cell 31. Each L-shaped retaining wall 1331 can limit two mutually perpendicular directions of the first battery cell 31 in the plane where the cover plate 133 is located, and the two L-shaped retaining walls 1331 are arranged diagonally, so that a better limiting effect can be exerted on the first battery cell 31.

Referring to fig. 11 and 12, it can be understood that in some embodiments, the retaining wall 1331 may be a continuous annular whole connected end to end, or a plurality of independent retaining walls 1331 are annular and arranged on the cover plate 133 at intervals.

In some embodiments, referring to fig. 13, along the direction perpendicular to the cover plate 133, the height T1 of the retaining wall 1331 and the thickness H2 of the first cell 31 satisfy: T1/H2 is more than or equal to 30% and less than or equal to 110%. Since the retaining wall 1331 mainly serves to mark and limit the first cell 31, rather than fix the first cell 31, the height of the retaining wall 1331 may be lower than the thickness of the first cell 31, and certainly, in consideration of the fact that the first cell 31 may expand during use, a certain expansion space is left between the first cell 31 and the retaining wall 1331, and the height of the retaining wall 1331 may also be appropriately greater than the thickness of the first cell 31 due to the protection effect on the first cell 31.

Referring to fig. 13, a gap exists between the retaining wall 1331 and the first cell 31, and a distance D of the gap satisfies: d is more than or equal to 0mm and less than or equal to 2mm.
