If a patent No. is the Chinese utility model patent electric drill of conveniently assemble and disassemble " a kind of power brick can " of ZL200820083853.6 (notification number is CN201168806Y), and one the patent No. be the Chinese utility model patent " be convenient to handling power brick " of ZL201020271676.1 (notification number is CN201728641U), they have all disclosed so a kind of lithium battery bag.
Lithium battery bag is easily heating in use, overheated lithium battery bag can affect the useful life of lithium battery, accelerate the aging of lithium battery, it does not arrange specially louvre existing lithium battery bag on shell, and due to directly contact between charged lithium cells, there is no sufficient heat-dissipating space, these factors all cause lithium battery bag radiating effect poor, have a strong impact on the useful life of lithium battery, the once service time after charging, existing lithium battery bag is directly placed in housing in addition, do not form good location with housing, and electric tool in use has certain vibrations, the vibration resistance effect of existing lithium battery bag is poor, cause battery and getting loose of wiring board connecting line in power brick and produce fault.
Summary of the invention
Technical problem to be solved in the utility model is the lithium battery bag that a kind of good heat dissipation effect is provided for above-mentioned prior art present situation, this lithium battery bag have advantages of long service life, once charging after service time long.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of lithium battery bag, comprise shell and be located at the lithium battery group in shell, the battery part that lithium battery group comprises wiring board and is connected with wiring board and connected to form by several charged lithium cells, it is characterized in that: the two ends, left and right of described battery part constrain in respectively on a support, this support makes the each charged lithium cells in battery part form each other heat radiation gap, the end face of described shell is provided with louvre, and the bottom surface of shell is provided with lower louvre.
On above-mentioned support, have some jacks that are intervally installed, the end corresponding setting one by one of described jack and charged lithium cells, the respective ends of charged lithium cells is plugged in corresponding jack.First jack retrains the end of charged lithium cells, owing to being intervally installed between jack, guarantees to be plugged in self-assembling formation heat radiation gap between the adjacent charged lithium cells on support.
Above-mentioned jack is many row's multiple rows to be arranged, the position, boundary of adjacent jack has auxiliary heat dissipation hole, and this auxiliary heat dissipation hole communicates with described heat radiation gap.Auxiliary heat dissipation hole is set can be gone out the heat quick heat radiating of heat radiation spatial summation, strengthens radiating effect.
Above-mentioned shell is formed by connecting by base and upper cover, and described upper louvre is arranged on and covers, and described lower louvre is arranged on base.This shell mechanism is convenient to battery component to be assembled in shell.
Further improve, the top of above-mentioned support is provided with at least two upwardly extending reference columns, and the inner top surface of described upper cover is provided with the jack matching with described reference column, is connected under the state on base at top cap, and described reference column is plugged in described jack.Support is pegged graft by reference column and the jack above covering, and can by firm battery pack constraint in the enclosure, strengthen the vibration resistance effect of power brick.
The bottom surface of above-mentioned support, front-back all with the Surface Contact of shell inner cavity.Each of support all contacts and can better retrain battery pack with shell inner cavity bottom surface, further strengthens the vibration resistance effect of power brick.
Compared with prior art, the utility model has the advantage of: the each charged lithium cells in lithium battery bag in battery part forms heat radiation gap each other, the end face of shell is provided with louvre in addition, the bottom surface of shell is provided with lower louvre, the heat that this power brick produces can be effectively by battery some work time can shed fast by heat radiation gap, upper louvre and lower louvre, radiating effect strengthens greatly, effectively extend the useful life of power brick, and service time of the power brick after charging once.
