Example one

As shown in fig. 1 to 3, the present embodiment provides a lithium battery 10 for a mobile phone, which is disposed in cooperation with a mobile phone casing (not shown). The cell-phone casing has seted up the storage tank of being connected with the cooperation of cell-phone lithium cell 10 downwards at its upper surface, and the cell-phone casing has seted up the groove of dodging the finger backward in the back cell wall department of storage tank.

The rear surface of the lithium battery 10 of the mobile phone is provided with a clamping groove 121 which extends left and right and is used for inserting a fingernail of a person, and the clamping groove 121 is arranged opposite to the avoiding groove.

In the storage tank is arranged in to cell-phone lithium cell 10, when disassembling, stretch into the groove of dodging with the people hand, nail butt draw-in groove 121 tank bottom and to lift away from cell-phone lithium cell 10, take out to the direction that deviates from the storage tank.

The cell-phone lithium cell 10 that this embodiment provided, setting through draw-in groove 121, for the hand operation provides the fulcrum, draw-in groove 121 supplies the finger nail to put into, the last cell wall of draw-in groove 121 directly bears the ascending effort of nail for the effect face of nail, compare in finger butt cell-phone lithium cell 10 vertically surface and lean on its frictional force to produce ascending effort, effectively reduce to lift cell-phone lithium cell 10 from the required effort of applying of storage tank, the degree of difficulty of taking out cell-phone lithium cell 10 from the storage tank has effectively been reduced promptly, the angle of change says, the separation operation of cell-phone lithium cell 10 and cell-phone casing has been facilitated.

Referring to fig. 1, a lithium battery 10 for a mobile phone includes a battery body 11 and a bottom plate 12 connected to a lower surface of the battery body 11, and a card slot 121 is formed in the bottom plate 12. The bottom plate 12 is disposed to protect the battery body 11 and provide a working space for opening the card slot 121.

In this embodiment, the bottom plate 12 is attached to the battery body 11 by using an AB adhesive. The AB glue has high bonding strength and meets the requirement of the connection stability of the bottom plate 12 and the battery body 11.

The AB glue is a different name of two-liquid mixed hardening glue, one liquid is the glue, the other liquid is the hardening agent, the two liquids can be hardened after being mixed, and the AB glue is one of normal-temperature hardening glue which can be hardened without depending on temperature. The component A is acrylic modified epoxy or epoxy resin or contains catalyst and other assistants, and the component B is modified amine or other hardener or contains catalyst and other assistants. Mixing at a certain ratio. The catalyst may control the cure time and other adjuvants may control properties (e.g., viscosity, stiffness, flexibility, adhesion, etc.).

In this embodiment, the plurality of slots 121 are arranged in parallel. Considering the difference of staff, when the finger stretched into and dodges the groove, the height that the finger nail can reach cell-phone lithium cell 10 was slightly different, under the setting of a plurality of draw-in grooves 121, can solve the inconvenience that the difference that reaches cell-phone lithium cell 10 height brought because the fat thin difference of staff brought.

In the illustrated embodiment, there are two card slots 121 arranged in parallel. In other embodiments, the card slots 121 may be arranged in three, four, etc. In this embodiment, the slots 121 have the same length (extending direction), and only one slot 121 is disposed on the same horizontal plane. In other embodiments, a plurality of card slots 121 may be arranged at intervals on the same horizontal plane, that is, one card slot 121 may be divided into a plurality of segments.

Referring to fig. 2 and 3, all the card slots 121 are disposed symmetrically up and down, so that the overall positions of the card slots 121 in the up-down direction are the same regardless of whether the bottom plate 12 is disposed on the front side or the back side.

Further, the respective card slots 121 are arranged bilaterally symmetrically, so that the positions of the card slots 121 in the left-right direction are the same regardless of whether the chassis 12 is placed on the front side or the back side.

That is, each of the slots 121 is vertically symmetrical, and specifically, each of the slots 121 has a vertically symmetrical cross section. All the card slots 121 are formed in a vertically and horizontally symmetrical pattern. With this arrangement, the same effect can be achieved regardless of whether the bottom plate 12 is placed on the front side or the back side, that is, the bottom plate 12 is placed without a directional requirement, thereby facilitating the assembling operation.

Referring to fig. 3, in the present embodiment, the cross section of the slot 121 is an isosceles trapezoid with a wide back and a narrow front. This arrangement makes the corner between the base plate 12 and the card slot 121 an obtuse angle, thereby reducing the risk of being scratched when operated by a human hand. The specific angle of the obtuse angle can be set by those skilled in the art according to actual needs, and is not limited herein.

In another embodiment, the slot 121 is rectangular in cross-section. This setting makes the corner between bottom plate 12 and the draw-in groove 121 be the right angle, and this setting makes the nail upwards raise battery body 11 the time, and draw-in groove 121 has the biggest vertical ascending effort to furthest reduces the degree of difficulty of operation.

Referring to fig. 1, the length of the card slot 121 along the extending direction is not less than three-quarters of the lithium battery 10 of the mobile phone. As will be appreciated by those skilled in the art, increasing the length of the slot 121 advantageously increases the working space for manual operation. Alternatively, the locking groove 121 and the avoiding groove are disposed opposite to each other, and the size thereof can be adjusted as needed. The appropriate increase in the length of the card slot 121 reduces the restrictions placed on the position of the avoidance slot.

Referring to fig. 1 and 2, the lower surface of the base plate 12 and the side surfaces thereof form an angle of a right angle. Because the space of storage tank need can supply cell-phone lithium cell 10 to put into from the top with cell-phone lithium cell 10 cooperation simultaneously, consequently, the cell wall of storage tank and the lower surface shape angle of the cell-phone casing rather than being connected are the right angle. The lower surface of bottom plate 12 and its side surface form an angle be the right angle be provided with do benefit to the cooperation compactness that improves bottom plate 12 and storage tank, improve the connection fastening nature between cell-phone lithium cell 10 and the storage tank promptly.
