Battery pack of the present invention is through being provided with the elastic component that prevents to produce between upper and lower compressing tablet and fixture stress relaxation in the lug coupling assembling; Guarantee that lug is connected with the tight of upper and lower compressing tablet; Guarantee the fail safe and the reliability of battery pack, do not influenced the battery pack of assembling random capacity and voltage quickly and easily simultaneously.
Description of drawings
Fig. 1 is the three-dimensional exploded view of a part of the battery pack of an embodiment.
Embodiment
To combine specific embodiment and accompanying drawing that battery pack of the present invention is described in further detail below.
As shown in Figure 1, in the preferred embodiment, battery pack mainly comprises a plurality of cell 10, be used for fixing and settle the battery carrier 20 of these a plurality of batteries 10 and be used for these a plurality of batteries 10 are electrically connected many groups lug coupling assembling of getting up.Every group of coupling assembling comprises that a lower sheeting 30, one go up compressing tablet 50, be used for preventing upper and lower compressing tablet and 60 a plurality of elastic components 41, a compressing tablet 40 fixing these a plurality of elastic components 41 and fixtures 60 that each compressing tablet is fixed together that produce stress relaxation of fixture.
In the present embodiment, battery 10 neatly is placed in the grid of battery carrier 20, and battery 10 end up all has positive pole ear 11 and negative lug 12 to stretch out.
In compressing tablet 40 be pressed on the lower sheeting 30, be formed with on it with lower sheeting 30 on the corresponding fixing hole of fixing hole.
Elastic component 41 is a spring, among other embodiment, also can be stage clip, compressing tablet, shell fragment, waveform sheet metal, silica gel, rubber etc. and under load force, can produce strain, remove the elastic component that load still can recover original physical dimension and shape.Elastic component 41 is fixed on middle compressing tablet 40 equably; Guarantee the upper, middle and lower compressing tablet closely make in the contact between each compressing tablet contact more evenly, increase the contact-making surface of battery pole ear and middle compressing tablet and middle compressing tablet and last compressing tablet 50, thereby the contact resistance and the battery loss of minimizing battery.In the present embodiment, elastic component 41 is welded on the middle compressing tablet 40.
Last compressing tablet 50 is pressed on elastic component 41, be formed with on the last compressing tablet 50 with lower sheeting 30 on the corresponding fixing hole of fixing hole.In the present embodiment, fixture 60 is a screw, corresponding, the said fixing hole is a screw.
When the actual assembled battery pack; At first the battery 10 of needs parallel connection is just being pressed; The direction that negative pole is identical is placed in the battery carrier 20 side by side; Needs series connected battery 10 by just; The direction that negative pole interlaces is placed in the battery carrier 20 side by side; Then just with battery; Negative lug 11; 12 pass groove 31 and the bending along the surface of lower sheeting 30 in the lower sheeting 30 respectively; The center platen 40 that will be formed with elastic component 41 then is placed on the lug top of bending; At last; Last compressing tablet 50 is placed on the top of elastic component 41; Make the corresponding screw alignment of three compressing tablets simultaneously, fixture 60 is passed screw be fastenedly connected.
During dismounting; Only need fixture 60 be taken off with a common screwdriver; Take out down then and middle compressing tablet 40,50; Just can dismantle the battery 10 that series and parallel connects; Change problematic monomer electricity core extremely easily; Lowered battery pack operation and maintenance cost greatly, the recycling that has increased battery is worth.
Among other embodiment, in middle compressing tablet 40 and the last compressing tablet 50 at least a slice be conductive metal sheet, as long as the lug coupling assembling can be used as electrode.Can adopt lower sheeting 30, middle compressing tablet 40 and the last compressing tablet 50 of different shape and size as required, the size that for example goes up compressing tablet 50 also can be less than the size of lower sheeting 30 and middle compressing tablet 40.Those skilled in the art are easy to expect, elastic component 41 can be fixed on the one side of the middle relatively compressing tablet 40 of compressing tablet 50, compressing tablet 40 in also can not adopting.Those skilled in the art it will also be appreciated that, can adopt other modes that elastic component 41 is fixed on the middle compressing tablet 40, for example on middle compressing tablet 40, offer location hole, and elastic component 41 is fixed in this location hole.Fixture 60 can adopt other fixtures 60 commonly used such as rivet.
To sum up, adopt lug coupling assembling of the present invention, can assemble the battery pack of random capacity and voltage quickly and easily.Owing to adopted elastic component 41, each interelement of lug coupling assembling can keep the stress tense situation for a long time, the electric connection of guaranteeing battery reliably and with long-term, stable.
Though the description of this invention combines above specific embodiment to carry out,, those skilled in the art that can carry out many replacements, modification and variation according to above-mentioned content, be conspicuous.Therefore, all are such substitute, improve and change all is included in the spirit and scope of attached claim.
