Description
Technical field
The present invention relates to a kind of accessory structure of electric car, and in particular to the knot that a kind of lithium battery for electric car is installed
Structure.
Background technology
With the progress of lithium battery technology, because under same battery capacity, lithium battery has in light weight, small volume excellent
Gesture, it is increasingly being applied on electric car, to substitute existing lead zinc battery.
The battery case of traditional electric car has two kinds of set-up modes, a kind of rear for being arranged on middle pipe, this structure meeting
The back segment of car body is elongated, causes to be difficult to the requirement for meeting ergonomics during Vehicle Frame Design；Another kind is arranged on front frame position,
A battery holding structure is fixedly installed above vehicle frame, battery case loads from top, is fixed in battery holding structure, this knot
The battery holding structure and the integraty of vehicle frame that structure is set are poor, influence the installation effect of battery case.
Chinese utility model patent CN205303556U discloses a kind of electric vehicle lithium battery box mounting structure, including battery
Box is complete and skew girder of vehicle frame, the box body are made up of upper lid, lower cover, and upper lid, lower cover be arranged in parallel up and down, are formed with battery box front end
Jack, mounting groove is formed with the skew girder of vehicle frame, in anterior mounting groove built with preceding battery case base, in preceding battery case base
It is provided with the tongue of key actuated, being locked to insert in jack by tongue of battery box and skew girder of vehicle frame is realized,
An arc-shaped limit groove to raise up is formed with the lower cover central axis of the box body, the mounting groove of the skew girder of vehicle frame is one
The mounting groove of front and rear opening, a spacing preiection being adapted with arc-shaped limit groove, the battery are formed with the mounting groove bottom land
The chimeric realization that the installation of box body and vehicle frame section bar passes through arc-shaped limit groove and spacing preiection.
The program battery case base before being set in the mounting groove on skew girder of vehicle frame, is matched somebody with somebody by structure design with battery case
Close and cause battery case to form continuous cabling in appearance with cant beam after mounting, make vehicle profile neat.But due to battery case
It is to coordinate to realize lateral register with the mounting groove on cant beam by the arc-shaped limit groove of box body, the battery case can only take from top
Go out, i.e., need certain space above battery case with dismounting cell box.Therefore, it is not applied for triangle frame structure.
In fact, just because of the installation question of battery case, current most electric bicycle is caused to abandon firm triangle
Body frame structure for automotive, and its stress performance must not be increased by increasing the thickness of vehicle frame body, cause electric bicycle vehicle body weight
Measure the problem of big.
