Abstract

The utility model belongs to the field of electric vehicle power battery packs and relates to a novel battery polar column and a connecting plate, in particular to a fast male and female connection structure of a battery pack. The fast male and female connection structure comprises a battery and the connecting plate and is characterized in that the battery is provided with a male column pile connected with an anode and a cathode in the battery, and a female column pile matched with the male column pile is fixed on the connecting plate. The male column pile is a cylinder with the outer surface provided with an arc-shaped protrusion, a groove is arranged in the middle of the outer portion of the female column pile, a spring steel ring is arranged on the groove, and a rubber soft plate is arranged on one side of the connecting plate. Under the conditions of the battery with the equal capacity, the height of the fast male and female connection structure is lowered to be favorable for arrangement. Under the conditions that the equal current passes, the area of materials required for the column piles is small, the fast male and female connection structure is rapid to install and suitable for rapid manufacturing of the battery pack, the column piles do not need stressing, the internal structure of the battery is not damaged, and the service life of the battery is guaranteed. The connecting plate is high in reliability and convenient and safe to use, and suspension voltage cannot be formed easily internally.

Description

A kind of quick male and female syndeton of battery pack
Technical field
The utility model belongs to electric automobile power battery group field, relates to the invention of a kind of novel battery pole and connecting plate, applies to especially battery and forms fast power brick male and female syndeton.
Background technology
Along with the research and development output of electric automobile is increasing, also harsher to the requirements of battery pack, not only the performance parameter of battery there is higher requirement, battery is installed also had higher requirement.
The electrokinetic cell Battery pack connected mode of present nearly all used for electric vehicle is all with bolts, by various screw rods conductive plate is screwed in the screwed hole on the battery, finishing the connection of cell positive/negative plate through test of many times needs about 10s consuming time, as finish a power brick all connection work are installed, the general time is all more than 15min, and occur easily unexpected in the operating process, cause battery and personnel injury, and each battery tie down screw is because the moment that operating personnel tighten is different, cause that the long-time large electric current operation of loose contact is overheated burns or situation that tension destroys the inside battery structure occurs, so that security performance reduces greatly, shortens battery.
Summary of the invention
The purpose of this utility model is the quick male and female syndeton that proposes a kind of battery pack.
Main technical schemes of the present utility model: the quick male and female syndeton of battery pack, comprise battery and connecting plate, it is characterized in that battery is provided with the public pile that is connected with the inside battery both positive and negative polarity, is fixed with the female stanchion that matches with male stanchion on the connecting plate; Described public stanchion is that outer surface has the cylindrical of arc-shaped convex, and the outside middle of described female stanchion has a groove, and groove is provided with steel rim of spring; Connecting plate one side has rubbery flexible sheet.
Syndeton of the present utility model, because the cooperation of male and female stanchion, pile reduces about 15mm than the battery total height with capacity, pole material economy about 40%, the positive and negative terminals material adopts copper or stainless steel is made, connecting plate adopts copper material to make, and become to connect flexible cord and connecting plate forces together with copper wire woven, according to battery mounting means in groups, connecting plate is fixed on the rubbery flexible sheet plate, and the rubbery flexible sheet plate folds, will be with the connecting plate of female stanchion and rubbery flexible sheet one by one by on the male pile of battery after last power brick installs, battery strings is linked togather, forms the power brick of high pressure.
Advantage of the present utility model compared with prior art:
1, under the battery of equal capacity, highly decreases, more be conducive to arrange;
2, in the situation by equal electric current, the required material area of stanchion is less;
3, install fast, be more suitable for the quick Fabrication of power brick;
4, stanchion need not stressedly, does not destroy the inside battery structure, guarantees battery life;
5, the connecting plate reliability is high, and is easy to use, safe, the inner formation suspended voltage that is difficult for.
Description of drawings
Fig. 1 is battery and public stanchion perspective view among the utility model embodiment; Fig. 2 is connecting plate perspective view among the embodiment; Fig. 3 is the three-dimensional structure for amplifying schematic diagram of female stanchion among the embodiment.
Among the figure, the 1-battery; The public stanchion of 2-; The female stanchion of 3-; The 4-connecting plate; The 5-rubbery flexible sheet; The 6-steel rim of spring.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.
Embodiment: battery pack fast joint structure, shown in Fig. 1,2 and 3, mainly comprise battery 1 and connecting plate 4, it mainly improves is that battery 1 is provided with the public pile 2 that is connected with battery 1 inner both positive and negative polarity, is fixed with the female stanchion 3 that matches with male stanchion 2 on the connecting plate 4; Described public stanchion 2 has the cylindrical of arc-shaped convex for outer surface, and the outside middle of described female stanchion 3 has a groove, and groove is provided with steel rim of spring 6; Connecting plate 4 one sides have rubbery flexible sheet 5.
Among the embodiment, two positive and negative public piles 2 are stretched out in battery 1 upper end, and public pile 2 highly is 20mm, and outer surface has the cylindrical of arc-shaped convex; The form of putting according to battery pack is fixed together female stanchion 3 with connecting plate 4, the inner structure form of female stanchion 3 matches with male stanchion 2 external structure forms, one end of female stanchion 3 connects by the wire on the connecting plate 4, female stanchion 3 outside middle grooves that have, card one steel rim of spring 6 to guarantee after being pressed into the battery pile, can tightly block the battery pile in the groove, guarantee to connect tightness and fitting area, guaranteed the safety of electric current.
Connecting plate 4 also is fixed on the rubbery flexible sheet 5 by glue special, rubbery flexible sheet 5 can twist in together, after battery installs, will with the connecting plate 4 of female stanchion 3 and rubbery flexible sheet 5 one by one by on the male stanchion 2 of cell, can form fast the high-tension battery bag.After the moment of connecting plate 4 usefulness 50N.m is pressed on the public pile 2 of battery, public pile 2 all is connected plate 4 and wraps, so that contact-making surface is larger than the contact-making surface of existing thread forms, to such an extent as to will save much by the material of the utility model use in the situation of same current.
Present embodiment has been innovated structural design at the positive and negative pile of battery, by battery and connecting plate male and female stanchion fit form, and the steel rim of spring that an automatic tightening is arranged at female stanchion, connecting plate and battery combine closely, to guarantee battery still normal operation under the 5c of specified volume discharge-rate, and all connecting plates are fixed together by the series system of fire-retardant rubbery flexible sheet according to battery in the electrokinetic cell bag, in power brick, be well placed after the battery, link together into a high-tension battery bag with battery fast with arranging the connecting plate that fixes, and finish this process, consuming time generally in 1min, not only guaranteed fail safe but also so that the tightness of battery be consistent, compare with existing battery connecting construction, greatly improved operating efficiency and reduced personnel's input, be more applicable for and produce in enormous quantities and manufacturing.
