Description
Technical field
The utility model relates to a kind of green long circulating power batteries, belong to power battery technology field.
Background technique
Domestic electric vehicle is using lead-acid accumulator mostly as power battery at present, and there are cruising ability shortcomings, electricity
The short disadvantage of pond service life, general lead-acid accumulator was needed replacing using 1 year or so, and lead-acid accumulator green
Environmental pollution is larger during production.Lithium ion battery can be improved because having higher energy density as power battery
The cruising ability of electric vehicle, and the less pollution in its preparation process are a kind of green long circulating batteries.But lithium ion battery is used
When making power battery of electric vehicle, it is preferred that emphasis is its safety problem.Lithium ion battery is easy to produce internal short-circuit when being impacted
And on fire or even explosion, and electric vehicle is unavoidable in the process of moving can generate vibration, especially when there is fortuitous event, by force
Big impact force is easy to cause the on fire of lithium ion battery or explosion.
Utility model content
The purpose of this utility model is to provide a kind of green long circulating power batteries, the specific scheme is that
A kind of green long circulating power battery, including multiple single batteries and frame, the frame include integral structure
Side frame, the side frame be multilayer folding structure, the inner wall of side frame includes the connection wall at multistage interval, every section of connection wall
Equipped with card slot, the cell wall of card slot is to be obliquely installed relative to the short transverse of side frame；The upper and lower part of two side frames is logical
It crosses cover board and connects and composes frame, multilayered thermally-conductive plate is equipped between two side frames, single battery is arranged between adjacent heat-conducting plate,
The two sides of the heat-conducting plate are embedded in the card slot of side frame, and the walls parallel of heat-conducting plate and card slot.
Further, the rear portion of the heat-conducting plate is equipped with L-shaped flange, the spacing one of the height of flange and adjacent card slot
It causes.
Further, the inner and outer wall of the side frame is arc-shaped transition；The lamination surface of side frame is equipped with bolt hole.
Further, the cover board is L shape, and the both ends of cover board are equipped with bolt hole corresponding with side frame, the inside of cover board
Equipped with triangular shaped elastomeric backing plate.
The beneficial point of the utility model is: the power battery in this programme uses the side frame of integral structure, is used for
Battery pack as single battery is assembled into module, the side frame of integral structure can provide firm support, prevent
Extruding is generated to battery pack when being impacted；In addition, it has been recognised by the inventors that the impact force that power battery in actual use, is subject to
It is consistent with gravity direction mostly, and power battery at this stage is that battery pack is arranged to lying fashion, although this field
Technical staff thinks which is conducive to the service life of battery, but in shock resistance, due to battery pack face direction with
Impact force is vertical, it is easier to be deformed extruding.Creatively the face direction of battery pack is arranged to and side frame in this programme
It is at certain angle of inclination, can effectively mitigate the impact force that battery pack is subject to.Due to using the above structure, the lithium of this programme
Ion battery has preferable security performance.
Detailed description of the invention
Fig. 1 is the power battery structure schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of side frame in the utility model；
Fig. 3 is the structural schematic diagram of heat-conducting plate in the utility model.
Specific embodiment
A kind of green long circulating power battery as shown in Figs. 1-3, including multiple single batteries 1 and frame, the frame
Side frame 2 including integral structure, the side frame 2 are multilayer folding structure, and the inner wall 3 of side frame includes multistage interval
Connection wall, every section of connection wall are equipped with card slot 4, and the cell wall of card slot 4 is to be obliquely installed relative to the short transverse of side frame, cell wall with
The angle of side frame short transverse is preferably 70~85 °；The upper and lower part of two side frames connects and composes frame by cover board 5
Frame is equipped with multilayered thermally-conductive plate 6 between two side frames, and heat-conducting plate uses aluminium sheet structure, and single battery is arranged in adjacent heat-conducting plate
Between, the two sides of the heat-conducting plate are embedded in the card slot of side frame, and the walls parallel of heat-conducting plate and card slot.
Specifically, the rear portion of the heat-conducting plate is equipped with L-shaped flange 601, the spacing one of the height of flange and adjacent card slot
It causes, heat-conducting plate is after stacking, and towards unanimously, flange and side frame enclose and constitute accommodating cavity open at one end, single battery flange
It is arranged in the accommodating cavity.The electrode connecting end of single battery is located at the open side of the accommodating cavity, facilitates connection conductive sheet.
Specifically, the inner and outer wall of the side frame is arc-shaped transition, inner and outer wall uses arc-shaped transition can be with
Make side frame that there is certain elasticity, certain prestressing force can be applied by connecting bolt 7 in assembling, to resist impact
Power；Correspondingly, it is equipped with bolt hole in the lamination surface of side frame, for installing connection bolt.
In addition, the cover board 5 is L shape, the both ends of cover board are equipped with bolt hole corresponding with side frame, and the inside of cover board is equipped with
Triangular shaped elastomeric backing plate 8.After completion of assembly, the side frame of two sides offsets one from another one end distance in height, to facilitate and lead
The gradient of hot plate cooperates.
