Abstract
The utility model relates to a polymer battery metal shell structure, which comprises an electric core and a shell, wherein the shell is formed by coating a single metal foil at the outer side of the electric core, and the metal foil is fixedly connected with the electric core through adhesive, and the rear end part of the electric core is provided with a rear cover, and the gap between the rear cover, the electric core and the metal foil is filled with filler gum; a bracket, a circuit board and a front cover are inserted in the front end of the electric core in turn; at least the gap between the bracket and the electric core is filled with filler gum; the circuit board is electrically connected with electrodes of the electric core; and an electrode connection plate which is led out from the circuit board is inserted in the front cover. By utilizing the metal foil to wrap the electric core, not only the strength requirement is satisfied, but also the circumferential thickness of the battery can be effectively reduced; the thickness and the width can be reduced by 0.4; and the metal shell has abrasion resistance and impact resistant capacity, thereby effectively protecting the application security of the electric core.
Description
Technical field:
The utility model relates to a kind of portable power source, especially a kind of encapsulating structure of polymer battery electricity core.
Background technology:
In mobile digital equipment industry, along with people use the universalness of equipment and to many requirements of functions of the equipments, continued power ability for device battery has had higher requirement, so, under existing situation, security performance and capacity for battery have had higher requirement, and lithium ion polymer battery relies on high power capacity and good security performance and be subjected to increasing application.Yet if by traditional shell packaged type of moulding, owing to be subjected to the restriction of injecting condition, it is bigger to take up room.
Summary of the invention:
The purpose of this utility model is that design a kind ofly both can effectively be protected battery safety, can improve battery capacity under same space again.
Technical solutions of the utility model are achieved in that a kind of polymer battery metal shell structure, comprise electric core and shell, it is characterized in that shell is to be wrapped in the electric core outside by the unitary piece of metal thin slice to form, pass through the colloid cementation between sheet metal and the electric core, electricity core rearward end is embedded with a bonnet, bonnet and electric core, the sheet metal gap is filled with filling glue, electricity core front end is embedded with support successively, circuit board and protecgulum, at least the gap between support and electric core is filled with filling glue, circuit board is electrically connected with electric core electrode by electrode connecting piece, and output electrode is convexly equipped with on protecgulum on the circuit board.Utilize sheet metal to wrap up electric core and both satisfied requirement of strength; can effectively reduce the thickness all around of battery again; and in order to keep electrode and equipment to have satisfactory electrical conductivity, the forward and backward lid that its shell and two ends are provided with is formed rigid body, protects electric core not to be subjected to external force in normal operating position.
Described sheet metal inner surface is compounded with glued membrane, and itself and the thermo-compression bonding of forward and backward lid contact site can guarantee the well secured of shell and forward and backward lid.
The utility model is compared with traditional product, and thickness and width all can be saved the space more than 0.4, and encapsulating structure is simple, and metal shell has more and resistance to wears and impact resistance, effectively protects the safe in utilization of electric core.
