Description
Technical field
The utility model relates to a kind of lithium battery group, is specifically related to the lithium battery group of a kind of collector plate and the riveted joint of battery plastics location-plate hot melt.
Background technology
At present, in New-energy electric vehicle industry, because lithium battery environmental pollution is little, noiselessness, energy advantages of higher, now be used as the power source of new-energy automobile, its groundwork principle is to provide electric energy by lithium battery to motor, drive motor running, thus propelling vehicle advances.Conventionally multiple battery cells are carried out to connection in series-parallel and get up to form jumbo battery pack, thereby reach the requirement to electric automobile power supply.In the series parallel structure of battery pack, be mainly made up of battery cell, battery plastics location-plate and collector plate, wherein battery plastics location-plate is mainly realized battery cell is positioned, and plays the effect that battery skeleton supports in battery pack; Collector plate is installed on battery plastics location-plate, and the electric current of mainly realizing battery cell collects; Electrode slice is the electric conductor that connects collector plate and battery cell, plays battery cell electric current is transmitted to the effect in collector plate.
The way at present collector plate being installed on battery plastics location-plate is often that the method being fixed by metal screw or plastics screw realizes being fixedly connected with between the two.Generally on battery plastics location-plate, to open screw hole, in collector plate, drive again location hole, then the screw hole of corresponding collector plate location hole battery plastics location-plate is installed, collector plate is fixed on battery plastics location-plate by metal screw or plastics screw.There is following shortcoming in this structure: the cost of (1) metal screw or plastics screw is high; (2) while assembling, need install one by one, installation work-hour cost is higher; (3) manual installation wastes time and energy, if realize with automatically disguising screw, equipment cost is higher; (4) can, because vibration makes screw loose or dislocation, there is potential safety hazard in the process of moving in bolt connection.
Utility model content
The purpose of this utility model is just to provide that a kind of cost is low, the lithium battery group of the safe collector plate that is connected firmly and the riveted joint of battery plastics location-plate hot melt.
In order to reach above-mentioned effect, the utility model provides the lithium battery group of a kind of collector plate and the riveted joint of battery plastics location-plate hot melt, comprise battery plastics location-plate, collector plate, on described battery plastics location-plate, be installed with reference column, in described collector plate, offer the location hole matching with described reference column, described collector plate is set in the reference column on described battery plastics location-plate and is riveted collector plate is fixed on battery plastics location-plate by hot melt by location hole.
The preferred version of such scheme is that the bottom face of described collector plate is installed with electrode slice.
The preferred version of such scheme is that the height of described reference column is not less than the twice of collector plate thickness.
More excellent technical scheme, described reference column and battery plastics location-plate are integrated injection moldings.
The utility model by integrated injection molding reference column on battery plastics location-plate, in collector plate, offer corresponding location hole, then location hole is enclosed within on reference column, adopt hot melt riveting technique to carry out hot melt riveting to reference column and become mushroom to be fixed on collector plate outer face, thereby collector plate is fixedly installed on plastics location-plate.
Hot melt riveting technique is by heating of metal instrument, metal tools is reached after the fusing point of hot melting plastic workpiece, metal tools is applied pressure on plastics part, thereby make plastics part meet the requirements of plastic shape after hot melt, shaping, cooling fixing, thereby play the object of fixing collector plate, it is fixing that hot melt riveting can carry out the hot melt shaping simultaneously of many heat fusion joints as required, and its production efficiency is high.
The utlity model has with beneficial effect:
1, the utility model carries out hot melt riveted joint by the reference column on battery plastics location-plate and fixes with collector plate, has saved screw, thereby has greatly reduced product cost.
2, between the battery plastics location-plate in the utility model and collector plate, be fixedly connected with and can use platform hot-melting tool many fixing points to be carried out to hot melt riveting to fix simultaneously, thereby greatly improved production efficiency, reduced product time cost.
3, after plastic column hot melt is shaped, collector plate and fully integratedization of battery plastics location-plate fusion and very close to each other, has avoided screw to be connected to prolonged exercise and can produce loose or dislocation phenomenon, thereby has greatly improved the security performance of electric automobile.
