Abstract
The utility model relates to technical field of lithium ion, more particularly to a kind of novel battery connecting bracket, including by multiple battery compositions battery pack, the battery cathode connection elastic slice of described battery one end be set, be provided with the insulating support and busbar connector of multiple through-holes；The battery connects elastic slice by the battery cathode and is fixed on the insulating support, and the battery cathode connection elastic slice passes through the through-hole and connect with the busbar connector.The utility model connects the design of elastic slice, insulating support by battery cathode, when the battery pack, which needs repairing, to be dismounted, it only needs the elastic force for overcoming the battery cathode connection elastic slice by external force that dismounting can be completed, any damage is had no to battery itself, it is easy to disassemble.
Description
Technical field
The utility model relates to technical field of lithium ion, more particularly, to a kind of novel battery connecting bracket.
Background technique
For current power battery market, circular battery and rectangular cell are always two different directions.Especially with
Tesla is that the passenger car aspect of representative is more likely to select cylindrical electrical core, and 21700 batteries are represented as emerging battery,
The energy density of 21700 battery systems is about improved in 300Wh/kg or so, the 250Wh/kg of 18650 battery system more original than its
20%.The promotion of battery cell battery capacity means that the quantity of required battery core under equal energy reduces about 1/3, drops since then
Low system administration difficulty simplifies the number of fitting parts such as hardware, although the weight and cost of single battery core,
The weight and cost of battery system PACK is but reduced.
It is mainly still realized by the electric resistance welding to battery bottom in most of cylindrical battery cathode connection at present,
Although connection is reliable, once performance occur bad for some battery, can not replace.In addition, fluffy with electric car industry
The echelon Utilizing question of the exhibition of breaking out, power battery will also bring into schedule, and the battery of resistance welding mode does not have to be decoupled again
The problem of possibility, echelon utilizes, does not just know where to begin yet.
Utility model content
The purpose of the utility model is to overcome defects in the prior art, provide a kind of novel battery connection branch
Frame.
In order to achieve the above object, the utility model adopts the following technical solutions:
A kind of novel battery connecting bracket, including by multiple battery compositions battery pack, described battery one end is set
Battery cathode connection elastic slice, be provided with the insulating support and busbar connector of multiple through-holes；The battery passes through the electricity
Cathode connection elastic slice in pond is fixed on the insulating support, and the battery cathode connection elastic slice pass through the through-hole with
The busbar connector connection.
Battery cathode connection elastic slice includes and the matched cup dolly of the battery and the circular base is arranged in
The multi-disc elastic slice in seat ring week.
The elastic slice is 6-12 piece.
The through-hole is provided with fixed floor corresponding with the elastic slice.
Compared with prior art, the utility model has the beneficial effects that
The utility model connects the design of elastic slice, insulating support by battery cathode, tears open when the battery pack needs repairing
When dress, it is only necessary to dismounting can be completed by the elastic force that external force overcomes the battery cathode to connect elastic slice, had no to battery itself
Any damage, it is easy to disassemble.
Preferably, the design of elastic slice can both realize the fixed battery of interference, while in battery charge and discharge process, not only bottom
Battery is contacted, the elastic slice of side can also play shunting function, so that the ability for making battery itself pass through electric current is higher, it is more conducively whole
The quick charge of body battery pack and high power discharge.
And the design for fixing floor is calculated by size, it is ensured that the company of battery cathode the connection elastic slice and battery
It connects close.The height of the fixed floor guarantees the fixed stability of battery simultaneously.
Detailed description of the invention
Fig. 1 show the structural schematic diagram of the utility model；
Fig. 2 show the structural schematic diagram of battery cathode connection elastic slice；
Fig. 3 show the local detail structural schematic diagram of the utility model；
In figure, 1- battery, 2- battery cathode connects elastic slice, and 21- circle egative film, 22- elastic slice, 3- insulating support, 31- fixes
Floor, 32- through-hole, 4- busbar connector.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing
The utility model is described in further detail with most preferred embodiment.
Fig. 1-3 shows a kind of novel battery connecting bracket, including be made of multiple batteries 1 battery pack, be arranged described
Battery one end battery cathode connection elastic slice 2, be provided with the insulating support and busbar connector 4 of multiple through-holes 32；The electricity
Pond connects elastic slice by the battery cathode and is fixed on the insulating support, and the battery cathode connection elastic slice is worn
The through-hole is crossed to connect with the busbar connector.The busbar connector connect elastic slice with the battery cathode by Laser Welding mode
Weld together through the circular through hole of the insulating support.Thereby realize the whole in parallel of multiple battery cathode.And
When the battery pack, which needs repairing, to be dismounted, it is only necessary to overcome the elastic force of the battery cathode connection elastic slice can be complete by external force
At dismounting, any damage is had no to battery itself, it is easy to disassemble.
Battery cathode connection elastic slice includes and the matched cup dolly 21 of the battery and the circle is arranged in
The multi-disc elastic slice 22 in base ring week.The elastic slice is 6-12 piece.The design of elastic slice can both realize the fixed battery of interference, while electricity
In the charge and discharge process of pond, not only bottom contacts battery, and the elastic slice of side can also play shunting function, so that battery itself be made to pass through
The ability of electric current is higher, more conducively the quick charge of integral battery group and high power discharge.
The through-hole 32 is provided with fixed floor 31 corresponding with the elastic slice.The design of fixed floor passes through size
It calculates, it is ensured that the battery cathode connection elastic slice and battery is completely embedded.The height of the fixed floor is protected simultaneously
Demonstrate,prove the fixed stability of battery.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
