Utility model content
Main purpose of the present utility model is the multiple cells at battery two ends for positive and negative electrode, and a kind of battery pack is provided; Implementation structure compactness, fixation also have the effect that anti-vibration is pushed.
The utility model solves the technical scheme that its technical problem adopts:
A kind of battery pack, comprise square shell, described shell is made up of frame and upper cover, lower cover, covers the anti-overvoltage/overcurrent/excess temperature circuit board that is provided with power supply output wiring terminal, is connected with each battery by wire on described shell, and described circuit board is provided with circuit board signal output line; It is characterized in that, the inside of described shell comprises the array that divides the cell that is located at two ends to form with the contrary assembled arrangement of adjacent cell polarity by some positive and negative electrodes, the positive and negative electrode of adjacent cell connects by brace, end face and bottom surface at described array are respectively equipped with upper and lower supporting seat, the groove at the packed battery two ends of can crouching is set respectively on described upper and lower supporting seat, the intercommunicating pore that can expose battery electrode is set between interconnective battery grooves, and described upper and lower supporting seat is fixedly connected with by many support columns.
In the groove floor of described upper and lower supporting seat respectively and elastic buffer rubber cushion is set between battery upper and lower end face.
Being shaped as of described elastic buffer rubber cushion is circular.
The material of described elastic buffer rubber cushion is EPDM.
On described brace, attach insulating heat-conductive adhesive tape.
Mounting circuit boards protective cover on described circuit board, circuit board signal output line is drawn from described circuit board protective cover.
The beneficial effects of the utility model are: in the shell of battery pack, the groove at the packed battery two ends of can crouching is set respectively on upper and lower supporting seat, effectively self-contained battery; And, upper and lower supporting seat couples together by support column, both can make the bulk strength reliability of battery pack increase, can effectively limit again the position of each battery, prevent that each battery is in use due to Relative Vibration, the connection causing is snapped with battery and is damaged, and effectively prevents the battery damage that battery pack causes due to unbalance stress in the time of assembling.The intercommunicating pore that can expose battery the two poles of the earth arranging on upper and lower supporting seat, is convenient to arrange brace, and the position of adjusting intercommunicating pore can change the series-parallel system of array.In the groove floor of upper and lower supporting seat respectively and the elastic buffer rubber cushion arranging between battery both ends of the surface, in the time that battery pack is given a shock or push, can effectively prevent that battery from contacting firmly with supporting seat, play buffering, dividing potential drop effect, and can effectively prevent the situations such as intercell connection in vibrations the battery container breakage and the use procedure that cause snaps, becomes flexible, fracture.Between the positive and negative electrode of each cell, connect by brace, on brace, adhere to insulating heat-conductive adhesive tape, be conducive to battery heat radiation.Power supply output wiring terminal is placed in upper cover outside, is easy to outside connection.Circuit board has the effect of anti-overvoltage, overcurrent, excess temperature; Mounting circuit boards protective cover on circuit board, well protective circuit plate.Compared with prior art, the utility model provides a kind of battery pack, and its compact overall structure, fixation, reliability are high, effectively anti-vibration extruding, are of great practical significance.
