In one embodiment of the present application, the second protective cover 170 is provided with at least one void area.

In one example, a void area is provided at one end of the second protective cover 170. As shown in fig. 6, since a certain bending structure exists at one end of the first circuit board 160, in order to ensure that the second protection cover 170 can protect the first circuit board 160, a region of the second protection cover 170 corresponding to the bending structure at one end of the first circuit board 160 may be configured as a void area.

In one example, the second protective cover 170 may have a clearance area at both ends. The second protection cover 170 may further protect the first tab 121 and the second tab 122, and the first tab 121 and the second tab 122 generally have a certain thickness, so that, except for the bending structure at one end of the first circuit board 160, two ends of the second protection cover 170 may be set to avoid empty areas, so that the first tab 121 and the second tab 122 are also avoided.

Example 3

According to another aspect of the present application, an electronic device 200 is also provided. As shown in fig. 7, the electronic device 200 includes a battery compartment 220 and a battery 210, and the battery 100 is disposed in the battery compartment 220.

The electronic device 200 may be implemented as a mobile phone, a notebook, a tablet, or the like, which is not limited thereto.

In one example, as shown in fig. 7, the second insulating offset 230 includes an upper adhesive layer 231, a middle substrate layer 232 and a lower adhesive layer 233, and the upper adhesive layer 231 and the lower adhesive layer 233 are respectively disposed on the upper surface and the lower surface of the substrate layer 232. The second insulating adhesive tape 230 is fixedly connected with the bottom of the battery compartment 220 through the lower adhesive layer 233, and the second insulating adhesive tape 230 is fixedly connected with the lower surface of the battery through the upper adhesive layer 231, so that the battery is fixedly arranged in the battery compartment 220.

In one example, the glue sites on the second insulating glue 230 are acutely angled.

By setting the glue sites to an acute angle shape, when the battery 210 is taken out from the battery compartment 220 through the pulling part 110, the battery packaging film is separated from the second insulating glue paper 230 in a point-by-point process, so that the battery 210 can be more easily peeled off from the second insulating glue paper 230, and the battery packaging film can be prevented from being wrinkled due to the peeling between the battery packaging film and the second insulating glue paper 230, thereby reducing the deformation of the battery packaging film.

In one example, to further facilitate stripping of the battery 210 from the second insulating sticker 230, the direction in which the acute angle openings of the glue sites are oriented may be set opposite to the direction in which the battery 210 is removed from the battery compartment 220.

For example, for the upper adhesive layer 231 of the second insulating adhesive paper 230, a printing process may be adopted to partially remove the adhesive, so as to weaken the adhesive strength of the whole area of the second insulating adhesive paper, so that the adhesive points remained after the adhesive removal are in an acute angle shape, and the opening direction of the acute angle is opposite to the direction when the battery is taken out from the battery compartment 220.

In one embodiment of the present application, the electronic device 200 further includes a second circuit board 240, and the electronic device 200 is electrically connected to the battery through the second circuit board 240.

The second circuit board 240 may be a PCB (Printed Circuit Board ), an FPC (Flexible Printed Circuit, flexible printed circuit board), or the like, which is not limited thereto.

Illustratively, fig. 8 shows a schematic structural diagram of a second circuit board 240.

In one example, as shown in fig. 6 and 9, the first circuit board 160 has a third connection portion 161 thereon, the second circuit board 240 has a fourth connection portion 241 thereon, and the first circuit board 160 and the second circuit board 240 are electrically connected through the third connection portion 161 and the fourth connection portion 241.

Illustratively, after the first circuit board 160 is bent and positioned at a proper position of the sealing portion 130, the third connection portion 161 of the first circuit board 160 may be corresponding to the fourth connection portion 241 of the second circuit board 240 to achieve an electrical connection between the first circuit board 160 and the second circuit board 240.

In one embodiment of the present application, battery compartment 220 includes a first compartment 221 and a second compartment 222, wherein first compartment 221 is configured to house a battery and second compartment 222 is configured to house a second circuit board 240.

In one embodiment of the present application, a corresponding void-avoidance slot may be provided on the electronic device 200 to accommodate the pull-up portion.

To sum up, according to the battery, electronic equipment of this application embodiment, through being equipped with on the battery packaging film and carry the portion of drawing, after the battery assembly is to the battery compartment, when need taking out the battery because of other reasons, can drive the battery atress through pulling the portion of drawing to can overcome the peeling force of battery, make things convenient for the battery to take out, avoid the battery packaging film to take place the fold, guarantee to take out the performance of back battery, solve the battery because of there is not the portion of drawing in the battery compartment with the compartment wall of battery compartment draw in the diapire when laminating, the problem that the battery can not exert moment and can not take out.

In addition, compared with the mode of adopting easy-pull glue and easy-tear film, the mode of arranging the lifting part reduces occupied battery space and improves battery capacity by 2% -3.5%.
