Cell fixing device and electric motor car
The present invention relates to the battery of electric motor car and the technical field of auto-body assembly, particularly relate to a kind of battery
Fixing device and electric motor car.
In recent years, environmental pollution is increasingly severe, especially air pollution, has become as urgently to be resolved hurrily
One of problem, and vehicle exhaust is one of air pollution source, and therefore new-energy automobile is seasonable and go out,
Wherein electric motor car is the most widely used new-energy automobile, and motor wagon therein is due to its vehicle frame
Special construction, the layout and the technique for fixing that account for the battery of complete vehicle weight nearly 1/4th are urgently to be resolved hurrily
One of problem.
In prior art, solution to the problems described above is broadly divided into two kinds, and one is directly by fuel oil goods
The tank support of car is used for supporting battery case, further according to the spacing of the length adjustment tank support of battery case,
Finally it is bolted again；Another kind of method is to use rectangular steel pipe through being simply welded
Battery case bracing frame, then by bolt, bracing frame is fixed on vehicle frame sidewall, finally battery case is led to
Cross and be bolted in battery case bracing frame.
Owing to the battery of lorry and the weight of battery case generally more than fill the fuel tank weight ten times of fuel oil
Above, therefore directly utilizing the tank support of fuel oil lorry to support battery case, its intensity is far from
No more, reliability is very poor, there is potential safety hazard；And the battery case being welded with rectangular steel pipe supports
Frame, simply the local strengthening fixing intensity of battery case, and do not account for the concrete structure of Truck Frame Model,
Being only that the battery case bracing frame being welded and battery case hang over vehicle frame both sides, lorry uses the time slightly
Long, frame distortion will be caused, and owing to battery is to need often to safeguard, above two method
All it is unfavorable for later stage dismounting and safeguards.
