Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, good heat dissipation, can waterproof and the battery pack that extends battery.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of battery pack, wherein: comprise in parallel by some battery cells and arrange and be connected in series battery pack, the heating panel arranging forming and the battery protection plate that is located in described battery pack between described battery cell by orthoscopic; Between described battery cell, be provided with sponge, make to leave gap between described battery cell; Described heating panel contacts with described battery protection plate, and the described battery protection plate on described battery pack both sides is provided with wire hole, and the electric wire that connects the both positive and negative polarity of described battery pack stretches out through described wire hole respectively.The battery pack that orthoscopic is arranged facilitates the accurate connection of electric wire in parallel, and battery protection plate protection battery is not subject to the possibility that shell directly collides, protection inside battery.The sponge arranging between battery cell can separate keeping flexible between two battery cells, when making battery pack in use can occur to collide, between battery cell, can not bump and can protect better shape and the performance of battery, can extend the life-span that battery is used; And sponge has certain heat insulation function, when heat battery being produced at heating panel can shed quickly, sponge is owing to directly not contacting with heating panel, the heat that sponge absorbs can remain on certain hour and not scatter and disappear at once, make battery can keep the even of temperature, also can extend the useful life of battery.
In technique scheme, described sponge is arranged at four jiaos between battery cell described in every two, and the heat shedding of battery is uniformly distributed better.
In technique scheme, described heating panel is a kind of in heat-conducting plastic, heat conductive silica gel, aluminum heat conducting plate and phase-change heat-storage material, can carry out well the transmission of heat.
In technique scheme, 1 to 3 millimeter of described heat radiation thickness of slab, the blocked up or thin effect that all can affect heat transfer of mistake, this range effect is best, and the blocked up space utilization ability that can reduce battery pack.
In technique scheme, between described battery protection plate, enclose the place, gap connecing and be coated with waterproof material, increase water-proof function, prevent from intaking in humid environment or rainy weather, have influence on the use of battery; If do not use waterproof material in addition but put again watertight composition, in sealing, be can be relatively good, but thermal diffusivity be poor, too high in order to prevent battery temperature, or on the gap between battery protection plate, use the waterproof material that does not affect thermal diffusivity.
The beneficial effects of the utility model are: the battery pack that orthoscopic is arranged facilitates the accurate connection of electric wire in parallel, and battery protection plate protection battery is not subject to the possibility that shell directly collides, protection inside battery.The sponge arranging between battery cell can separate keeping flexible between two battery cells, when making battery pack in use can occur to collide, between battery cell, can not bump and can protect better shape and the performance of battery, can extend the life-span that battery is used; And sponge has certain heat insulation function, when heat battery being produced at heating panel can shed quickly, sponge is owing to directly not contacting with heating panel, the heat that sponge absorbs can remain on certain hour and not scatter and disappear at once, make battery can keep the even of temperature, also can extend the useful life of battery.Heating panel is used the material of high thermal conductivity can carry out well the transmission of heat.Between battery protection plate, enclose the place, gap connecing and be coated with waterproof material, increase water-proof function, prevent from intaking in humid environment or rainy weather, have influence on the use of battery; If do not use waterproof material in addition but put again watertight composition, in sealing, be can be relatively good, but thermal diffusivity be poor, too high in order to prevent battery temperature, or on the gap between battery protection plate, use the waterproof material that does not affect thermal diffusivity.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of battery pack, wherein: comprise in parallel by some battery cells 1 and arrange and be connected in series the battery pack forming, the heating panel 2 arranging and the battery protection plate 3 that is located in described battery pack between described battery cell 1 by orthoscopic; Between described battery cell 1, be provided with sponge 4, make to leave gap between described battery cell 1, some sponges 4 are laid in respectively in four corners between battery cell 1, and so the effect of insulation is also optimization; Described heating panel 2 contacts with described battery protection plate 3 and carries out heat transmission, and the described battery protection plate 3 on described battery pack both sides is provided with wire hole 5, and the electric wire that connects the both positive and negative polarity of described battery pack stretches out through described wire hole 5 respectively, after stretching out, is connected with circuit board.Battery protection plate 3 comprises round totally six up and down of the left-right and front-backs of battery pack, uses screw and screw to fix, but due to the assembleability between battery protection plate 3, be not fine in sealing between battery protection plate 3.
