After the electric core is packaged, the aluminum-plastic film can expose the aluminum foil in the middle layer after being cut (the aluminum foil generally appears on the side face 104 of the electric core), and in order to avoid short circuit danger, the aluminum-plastic film needs to be coated by materials such as insulating gummed paper and the like. The third injection molding body 42 of the present application can coat the place where the battery cell 10 needs to be insulated, protect the battery cell 10, and replace and omit the insulating adhesive tape. The place where the battery cell 10 needs to be insulated is generally a side sealing edge of an aluminum plastic film, the side sealing edge is generally located on the side surface 104 of the battery cell, and the third injection molded body 42 at least covers the side sealing edge of the battery cell 10.

The battery and the electric device according to some embodiments of the present application are described below by taking a lithium ion battery and a mobile terminal as examples, but it is understood by those skilled in the art that the application of the present application is not limited to the mobile terminal, and for example, the present application may also be applied to other electric devices such as a tablet computer.

Comparative example

At present, there are three main ways for fixing the internal battery:

the first is to adopt the fixing mode of easy-to-draw paste and double faced adhesive tape. Firstly, the detachable easy-to-pull sticker and the handle part are pasted on the battery, and then the high-viscosity double-sided adhesive tape is pasted on the surface of the easy-to-pull sticker, so that the battery can be fixed on the host machine. When the battery needs to be disassembled or repaired, the pull handle of the easy-to-pull sticker is pulled, the easy-to-pull sticker is separated from the surface of the battery, and then the battery can be disassembled.

The second is the mode of adopting easy-to-draw glue to fix. A protective film is pasted on one surface, close to the mobile terminal, of the battery, and then strip-shaped easy-to-pull glue is pasted between the battery and the mobile terminal, namely one strip-shaped easy-to-pull glue or even a plurality of strips of easy-to-pull glue are pasted between the battery and the mobile terminal, so that the battery can be fixed on the mobile terminal. When the battery needs to be repaired or disassembled, the easy-to-draw glue can be removed by slowly pulling the handle which is left outside by the easy-to-draw glue, so that the battery can be taken down.

The third is to stick double-sided adhesive tape between the battery and the mobile terminal. When the battery needs to be taken out, the battery can be taken out after the double-sided adhesive tape loses viscosity through violence disassembly or special solvent soaking in the double-sided adhesive tape in the battery bin.

In the process of taking out the battery by the first and second methods, the battery may be damaged and cannot be used again, the repair cost is high, and the battery can only be taken out violently if the handle is broken by carelessness. Moreover, the two designs require multi-layer material stacking, so that the space of the battery compartment is greatly occupied, the mobile terminal becomes thicker, or the capacity of the battery is reduced. And the material cost and the labor cost are greatly increased due to the reasons of large quantity of materials, high requirement on material performance, high requirement on attached operation normativity and the like. Although the third method occupies a small space, the battery taking process is difficult to operate, and the battery is scrapped after being taken out, so that the repair cost is greatly increased.

Example 1

For solving the contradiction that battery and mobile terminal both reliably fixed can conveniently be dismantled again, simplify the design simultaneously, the simplified operation, reduce cost's purpose, this application is synthetic one with a plurality of materials, and the material quantity reduces, and overall thickness reduces, and the operation is simplified, satisfies the demand of easy disassembly simultaneously functionally.

The periphery or the head and the tail of the battery are subjected to injection molding by using an injection molding process to form an injection molding body fastened on the battery core, the injection molding body not only plays a role in protecting the battery core, but also is used for fixing the battery core to the terminal by using some special structures. Most of protection and insulating gummed paper are replaced by the injection molding body, and when the injection molding body is fixed on a terminal, materials such as double faced adhesive tapes and wrapping films are not needed, so that the cost is greatly reduced. The battery and the terminal are fixed by adopting a buckle and/or a screw, so that the battery is very easy to disassemble, and the battery cannot be damaged. Because no material is on the surface of the battery, a large amount of space is saved in thickness, the whole host end can be made thinner, or the capacity of the battery can be greatly improved.

As shown in fig. 3, the battery head of the present application is provided with a protection plate holder 30, and a protection plate 20 is fixed to the protection plate holder 30. The protection plate 20 is provided with gold fingers 21 connected with terminals. The protective plate holder 30 can be molded prior to mounting to the battery using conventional injection molding techniques. The protection plate holder 30 is provided with a buckle 31. The gaps and the tails of the battery heads, or the gaps, the tails and the two sides of the battery heads are filled with plastic by Low pressure injection molding (LPM). The protective plate holder 30 is connected to the head of the battery cell 10 by a first injection molded body 40 formed during injection molding.

As shown in fig. 3 and 4, the structure of the battery is schematically illustrated by low-pressure injection molding at the gap of the head part and the tail part of the battery. The battery has a first injection molded body 40 in the head space and a second injection molded body 41 in the tail part. The second injection-molded body 41 of the tail part forms a step buckle (i.e. a clamping structure 410) during injection molding. The protective plate holder 30 of the battery head is also provided with a step catch (i.e., catch 31). The first injection molding body 40 and the second injection molding body 41 are attached to the battery cell 10 to provide insulation and protection effects for the battery cell 10, so that the battery formed by the battery cell is convenient to operate.

Fig. 5 is a schematic diagram of a battery structure with low-pressure injection molding on the gap, both sides and tail of the battery head. The head, tail and sides of the battery have injection molded bodies 4. The injection molded body 4 has a stepped catch (i.e., a snap structure 410) formed at the end portion during injection molding. The protective plate holder 30 of the head is also provided with a step catch (i.e. catch 31). The injection molded body 4 is attached to the battery cell 10, and provides insulation and protection for the battery cell 10.

In this embodiment, the form of the clip on the head protection plate holder 30 and the clip on the tail portion can be various, and for example, the clip may be a spring arm clip. The head and tail snaps are not limited to two in the drawings, and one or more snaps may be provided in the middle. Fig. 12 shows a schematic diagram of the elastic arm buckle arranged at the head of the battery, and the protection board bracket may not be provided with the clamping structure.

The number of the battery cells 10 in one battery in this embodiment may be two or more. The relative positions of the cells 10 may be "side-by-side", "end-to-end", etc.

The above is the structure of the battery, and the following describes the connection structure of the battery and the host (corresponding electronic device or electric device).

As previously described, as shown in fig. 12-15, the head and tail of the battery are provided with snaps (the aforementioned snaps 31 and snap structures 410) that mate with the structures 72, 73 on the battery compartment 71 of the host 7 to secure the battery. In the above fastening scheme, when the battery head is an elastic arm fastener, the battery compartment 71 has a mounting hole 72 corresponding to the elastic arm fastener.

In the first embodiment, as shown in fig. 12, the battery 100 is molded around, the latch 31 at the head of the battery is an elastic arm latch, and the engaging structure 410 at the tail of the battery is a step latch. The corresponding positions of the head and the tail of the battery compartment 71 are respectively provided with mounting hole positions 72 corresponding to the elastic arm buckle and the step buckle.

The assembly mode is as follows: the tail of the battery is inserted into the battery bin 71 to be installed on the hole position 72, then the elastic arm at the head of the battery is buckled and pressed down, and the elastic arm at the head is buckled with certain elasticity and interference, so that the battery can be assembled and fixed.

In a second embodiment, the injection molded body on the side of the battery is formed with a stepped snap. Optionally, the position of the snap-in of the elastic arm of the head may also be located on the second injection-molded body 42 on the side of the battery cell 10.

In the third embodiment, as shown in fig. 13 and 14, the latch 31 at the head of the battery 100 is a spring arm latch, and the latch structure 410 at the tail is a step latch. The battery compartment 71 of the main unit 7 is provided with a mounting hole 72 corresponding to the arm clip, and a clearance 73 for avoiding the step clip is provided at a position corresponding to the step clip. A cover plate 81 of the main body 7 for covering the device circuit board is provided with a protrusion 80 at a position corresponding to the clearance 73, the protrusion 80 being for pressing a step catch fitted into the clearance 73.

The catch 31 of the head of the battery 100 may also be a step catch. The mounting hole 72 of the battery compartment 71 corresponds to the step catch.

In the assembling process, firstly, the elastic arm buckle or the step buckle at the head of the battery 100 is inserted into the mounting hole 72 of the battery bin 71, the clearance 73 is designed at the position of the step buckle at the tail of the battery bin 71, and the step buckle at the tail of the battery 100 enters the clearance 73 and can be easily put down. Then, a circuit board cover plate 81 at the tail of the main unit is assembled, and a protruding structure 80 formed at a position of the cover plate 81 corresponding to the step catch at the tail of the battery 100 presses the step catch at the tail of the battery 100. The circuit board cover plate 81 at the tail of the main unit is fixed with the battery chamber 71 through screws. This allows the battery 100 to be easily fitted into the battery chamber 71 and stably held, and also allows easy removal when necessary.

In the fourth embodiment, as shown in fig. 15, the battery 100 is provided with step snaps at both the head and tail portions. Specifically, the latch 31 of the protection plate holder at the head of the battery 100 may be designed as a step latch, and the engaging structure 410 of the second injection-molded body 41 at the tail of the battery 100 may also be designed as a step latch. The battery compartment 71 of the main unit 7 has a first notch 73a at the head portion for avoiding the step catch at the head portion, and a second clearance 73b at the position corresponding to the step catch at the tail portion for avoiding the step catch. The first cover plate 81a of the main unit 7 for covering the main board of the device circuit is provided with a protrusion 80a at a position corresponding to the clearance 73a, and the protrusion 80a is used for pressing the step catch fitted into the clearance 73 a. A second cover plate 81b of the main body 7 for covering the device circuit sub-plate is provided with a protrusion 80b at a position corresponding to the clearance 73b, the protrusion 80b for pressing a step catch fitted into the clearance 73b

As shown in fig. 15, clearance 73a and 73b for avoiding the head step catch and the tail step catch are provided at the head and the tail of the battery compartment 71, respectively. The battery is pressed by the cover plates 81a, 81b at the head and tail of the battery container 71 at the same time. The cover plates 81a and 81b are structures that are usually found on a terminal host 7, and are usually used to cover a main board or a sub-board of the host for protection. It is only necessary to provide the protruding portions 80a, 80b at positions of the head cover plate 81a and the tail cover plate 81b corresponding to the spaces 73a, 73b, the protruding portions 80a, 80b being used to press the step snaps fitted into the two spaces 73a, 73b, respectively.

The invention fully utilizes the function of the terminal cover plate, does not increase the structural part additionally, and does not waste the space of the terminal.
