Abstract
The utility model relates to a kind of brace of battery pack, belongs to technical field of lithium ion, and the brace it solving battery pack of the prior art installs trouble, the problem of poor stability.The brace of this battery pack comprises body in the form of sheets, and body is provided with at least 3 bolts hole, is also provided with the elastic portion of curved projection between described adjacent two bolts hole.This brace, can the multiple positive source of disposable connection or negative pole by designing multiple bolt hole in battery pack use procedure, avoids same pole is arranged multiple brace and causes installing loaded down with trivial details and reduce and install stability; Can be effectively reduced because the reasons such as cell bulging or brace loosen cause the pulling force of cell pole spacing increase to brace by the elastic portion of arc convex, improve the unfailing performance of battery, and ensure reliability and the fail safe of battery; Bolt hole spacing and bolt internal diameter and stud external diameter and spacing match, and can ensure that stability installed by brace.
Description
Technical field
The utility model belongs to technical field of lithium ion, relates to a kind of insulating protection structure of Li-ion batteries piles.
Background technology
Along with the enforcement that national new forms of energy are planned, the electrokinetic cell of electric automobile also more and more receives much concern.Present lithium ion battery market demand is increasing, and known lithium ion battery need meet the requirements such as heavy-current discharge, high rate cyclic and longer useful life.Existing electric automobile needs to use a large amount of battery pack in producing, in order to need to carry out parallel connection and series connection to monomer battery core or battery pack when reaching high voltage and the high power capacity of battery.Battery pack conventional at present battery pack is fixed in casing by multiple battery cell box, battery core, lug fixed head etc.Therefore need in series or in parallel with each other for the lug of different monomers battery by electrode connecting piece.
In prior art, what the series and parallel connections of battery cell adopted is holes brace, directly brace is sheathed on the stud of cell, then by nut, brace is pressed on the stud of lug, but for a fairly large number of battery cell of connection in series-parallel, a lug stud often needs socket two braces, this just causes brace to install trouble, be difficult to ensure its installation strength simultaneously, when battery pack is arranged in electric motor car, because vehicle vibration also easily causes brace to loosen the bonding strength affecting battery with rocking.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of structure simple, cell connector easy to use.
The purpose of this utility model realizes by following technical proposal: a kind of brace of battery pack, it is characterized in that, comprise body in the form of sheets, described body is provided with at least 3 bolts hole, is also provided with the elastic portion of curved projection between described adjacent two bolts hole.
In the brace of above-mentioned battery pack, described body is provided with 3 ~ 6 bolts hole.
In the brace of above-mentioned battery pack, described bolt hole internal diameter is Φ 9mm.
In the brace of above-mentioned battery pack, described bolt hole spacing is 55mm.
In the brace of above-mentioned battery pack, described body outer application has wear-resistant coating.
Compared with prior art, this brace, can the multiple positive source of disposable connection or negative pole by designing multiple bolt hole in battery pack use procedure, avoids same pole is arranged multiple brace and causes installing loaded down with trivial details and reduce and install stability; Can be effectively reduced because the reasons such as cell bulging or brace loosen cause the pulling force of cell pole spacing increase to brace by the elastic portion of arc convex, improve the unfailing performance of battery, and ensure reliability and the fail safe of battery; Bolt hole spacing and bolt internal diameter and stud external diameter and spacing match, and can ensure that stability installed by brace.

Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Embodiment 1
As depicted in figs. 1 and 2, the brace of this battery pack, comprises body 1 in the form of sheets, and body 1 is provided with 3 bolts hole 2, is also provided with the elastic portion 3 of curved projection between described adjacent two bolts hole 2.Described bolt hole 2 internal diameter is Φ 9mm, and the spacing between described each adjacent bolt hole 2 is 55mm.For strengthening the useful life of brace further, outside described body 1, be also coated with wear-resistant coating.This brace, can the multiple positive source of disposable connection or negative pole by designing multiple bolt hole 2 in battery pack use procedure, avoids same pole is arranged multiple brace and causes installing loaded down with trivial details and reduce and install stability; Can be effectively reduced because the reasons such as cell bulging or brace loosen cause the pulling force of cell pole spacing increase to brace by the elastic portion 3 of arc convex, improve the unfailing performance of battery, and ensure reliability and the fail safe of battery; Bolt hole 2 spacing and bolt internal diameter and stud external diameter and spacing match, and can ensure that stability installed by brace.
Embodiment 2
As shown in Figure 3 and Figure 4, the structural principle of the present embodiment is substantially identical with the structural principle of embodiment 1, different places is, in the brace of this battery pack, body 1 is provided with 6 bolts hole 2, connect for the total negative pole of storage battery, can disposable connection 6 cell negative poles, effectively reduce the labour intensity that battery pack is installed.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Claims (4)
1. a brace for battery pack, is characterized in that, comprises body in the form of sheets, and described body is provided with at least 3 bolts hole, and be also provided with the elastic portion of curved projection between described adjacent two bolts hole, described body outer application has wear-resistant coating.
2. the brace of battery pack according to claim 1, is characterized in that, described body is provided with 3 ~ 6 bolts hole.
