Embodiment
Shown in Fig. 7, power brick 100 of the present utility model comprises: battery container 11, battery core combination 12, splicing ear 13, master control circuit board 14; This power brick 100 at least has the output voltage of 56V.With regard to the ability of output voltage, it can export the output voltage of at least 56.
Wherein, battery core combination 12 comprises more than one battery core unit 121, battery core combination 12 be one by multiple entirety that there is certain electrical connection and form according to the battery core unit 121 of certain structural arrangement, it is arranged on the energy source as power brick 100 in battery container 11.Certainly, the situation only containing a battery core unit 121 in battery core combination 12 is not got rid of.
Power brick 100 should form the structure of a relative compact at three dimensions, make it be convenient for carrying, and also makes it easy to plug-in mounting to corresponding charger 200 and electric tool 300.For the power brick 100 that output voltage is less, the Limited Number of its battery core unit 121, does not often need to consider that battery core unit 121 is arranged, and only makes them neatly arrange.
But for the utility model power brick 100, it at least has the output voltage of 56V, this makes them must possess relatively many battery core unit 121, and each battery core unit 121 possesses larger caloric value when powering and when charging.If according to existing proper alignment, power brick 100 internal heat can be made to concentrate, be difficult to discharge, occur potential safety hazard.And relatively many battery core unit 121 can not simply be arranged at a certain dimension Linear, and the profile of such power brick and size will extremely be unsuitable for carrying and installing.
So as a kind of preferred version, with reference to shown in Fig. 3, battery core unit 121 is cylinder, in order to make, the surface of the battery core unit 121 in battery core combination 12 is as much as possible exposes, battery core unit 121 can adopt arrangement mode as shown in Figure 3, if supposed with the maximum projection plane A of parallel battery core combination 12 for horizontal direction, the battery core unit 121 that in the vertical direction is adjacent staggers setting in the horizontal direction, and battery core unit 121 adjacent in the horizontal direction both can stagger to arrange and also can to have alignd setting, the volume making whole battery core combine 12 while having enough area of dissipations to make battery core unit 121 is unlikely to undue large, battery core unit 121 adjacent is in the horizontal direction that alignment is arranged.Also just says, in three-dimensional system of coordinate, multiple battery core unit 121 can two dimensions formation repeated arrangement wherein, and to stagger setting at the battery core unit 121 that remaining dimension is adjacent.Certainly, also can two dimensions, even three dimensions make adjacent battery core unit 121 all stagger setting.But significantly increase power brick 100 volume like this, make its structure not compact.So the scheme shown in employing Fig. 3, obviously can be taken into account in heat radiation and volume these two aspects.
With reference to the scheme shown in Fig. 3, it has not only carried out individual improvement in the mode of battery core unit 121 arrangement, it has made improvement in shape also in the overall battery core combination 12 be made up of battery core unit 121, as shown in Figure 3, when battery core unit 121 adopts the mode of Heterogeneous Permutation in a certain dimension, the entirety of battery core combination 12 is difficult to reconstruct regular three-dimensional shape.As a kind of preferred version, battery core combination 12 comprises: specular arranges left cell cube 122 and right cell cube 123 and arranges linkage unit body 124 between which; Wherein left cell cube 122 and right cell cube 123 form specular, their symmetrical minute surface combines the maximum projection plane A of 12 perpendicular to battery core, if with the maximum projection plane A of parallel battery core combination 12 for horizontal aspect, left cell cube 122 and right cell cube 123 all exceed linkage unit body 124 in upper and lower both sides, and they form two grooves 124a, 124b varying in size in the both sides of linkage unit body 124.
Specifically, left cell cube 122 and right cell cube 123 are all made up of three layers of battery core unit 121, every one deck has a lot at the battery core unit 121 of vertical direction alignment, the i.e. battery core unit 121 of repeated arrangement in the horizontal direction, every layer all relatively last layer to stagger to the side away from linkage unit body 124 setting, linkage unit body 124 is only made up of one deck battery core unit 121 and aligns at vertical direction with the intermediate layer of left cell cube 122 and right cell cube 123, the both sides of this one deck of linkage unit body 124 and left cell cube 122 and right cell cube 123 form the groove 124a of two vary in size (because the outer wrong reasons arranged of different layers) at one deck that its both sides have more, 124b.The beneficial effect of such setting is, for in left cell cube 122, all some exposes the cylindrical sides of all battery core unit 121, instead of completely surround by the battery core unit 121 of surrounding, so its each battery core unit 121 all effective distribute heats of energy, and it is concentrated to produce heat, right cell cube 123 is also identical, for linkage unit body 124, the both sides up and down of all battery core unit 121 included by it all do not stop the structure that they dispel the heat, so they more easily dispel the heat.
It should be noted is that, because the relatively left cell cube 122 in linkage unit body 124 place and right cell cube 123 are more prone to heat radiation, so when the heat that all battery core unit 121 distribute is suitable, heat can form to the both sides of linkage unit body 124 two grooves 124a, 124b varying in size by left cell cube 122 and right cell cube 123 and spread, especially larger groove 124b.
This is also the usefulness that battery core of the present utility model combination 12 is arranged to as shown in Figure 3, be convenient to when arranging battery container 11, the main aeration structure correspondence being used for dispelling the heat is arranged on groove 124b place, both larger area of dissipation can be obtained, again because this face, place three is battery core unit 121, radiating efficiency is high, be more cleverly, battery core combination 12 self just exists by the diffusion to groove 124b of left cell cube 122 and right cell cube 123, if again aeration structure is arranged on this place to do further to guide to heat diffusion, will make that heat is more efficiently diffuses out battery container 11, correspondingly can reduce the area of the aeration structure set by all the other positions of battery container 11, to ensure the structural strength of whole battery container 11.

The benefit of such design is: the utility model power brick at least has the output voltage of 56V, so the power brick of the relatively general low output voltage of the number of its battery core unit 121 and Yan Yaoduo, its size and weight are also relatively large, so when plug-in mounting in order to ensure to have enough contacts area to realize backstop perpendicular to cartridge insertion direction I and enough plug-in mounting length, its full-size direction M first needing parallel as much as possible battery core to combine 12 has obtained enough plug-in mounting length, secondly need the maximum projection plane A combining 12 as much as possible with battery core parallel, obtain enough areas to arrange for plug-in mounting structure 151, terminal interface 152 etc.
Known through testing, when the angle that maximum projection plane A, full-size direction M that cartridge insertion direction I and battery core combine 12 are formed is more than 45 degree, the increase with angle reduces by the obtainable length of cartridge insertion direction I.And generally speaking, in order to make power brick 100 compact conformation, the maximum projection plane A that maximum projection plane B and the battery core of battery container 11 combine 12 overlaps, so when the angle that the maximum projection plane A that cartridge insertion direction I and battery core combine 12 is formed is more than 45 degree, the housing area of the battery container 11 that plug-in mounting structure 151 can utilize also can increase along with angle and reduce.Therefore the utility model adopts design as above.
Preferably, cartridge insertion direction I can with battery core combine 12 maximum projection plane A parallel with full-size direction M.
As further preferred version, the maximum projection plane A that maximum projection plane C and the battery core of plug-in mounting shell wall 15 combine 12 overlaps, further, they all overlap with the maximum projection plane B of battery container 11, that is, battery container 11, battery core combination 12 has identical maximum projection plane B, A, and the maximal projection area C for the formation of the plug-in mounting shell wall 15 of plug-in mounting structure 151 in battery container 11 also overlaps with it.The object of such design is, battery container 11 can hold battery core combination 12 with the space structure of relative compact, and makes plug-in mounting shell wall 15 have sufficient size to form plug-in mounting structure 151.
