Safety requirements after 31498-2015 electric automobile collisions》Physical protection and electrolyte leakage after colliding is proposed to battery pack to want
It asks.Since power battery is mounted between public transport vehicle chassis lower part and battery side hatch door, and not enough spaces generate foot
Enough deformations absorb collision energy, it is therefore desirable to collision prevention girders are installed between power battery and battery hatch door to prevent side from hitting
Contact squeeze of the lower battery side hatch door to power battery is hit, to cause the damage of battery.
The existing anticollision device, collision-prevention device of electric motor coach mostly directly uses square steel, and square steel rigidity is limited, deformation is not exclusively controllable,
It is easily deformed after being hit and is even broken, serious pierceable battery case.To improve the crash-worthiness of battery flat, generally
Square steel rigidity and intensity are improved using square steel thickness is increased, but this mode can increase complete vehicle quality.
Invention content：
The present invention be in order to solve the above-mentioned problems of the prior art and to provide a kind of electric motor coach battery flat side impact anti-
Collision device.
The technical solution adopted in the present invention has：A kind of electric motor coach battery flat side impact anticollision device, collision-prevention device, including crossbeam, installation
Holder, vertical beam, diagonal brace and vehicle frame, two vertical beams are arranged on two grid faces of vehicle frame, auxiliary on every vertical beam to have diagonal brace,
Two mounting brackets are respectively welded on vertical beam, and the both ends of crossbeam are connect by bolt with mounting bracket；
The crossbeam is by the isometric angle steel welding fabrication of one section of groove profile part and three sections, the arrangement of three sections of isometric angle steel deciles
In the slot of groove profile part, the opening direction of angle steel is consistent with the opening direction of groove profile part；Trisection on the facade of groove profile part
Point position is provided with the circular hole of two a diameter of 6mm.
Further, the mounting bracket includes holder facade and bracket end face, and it is 40mm that holder facade, which cuts into specification,
× 30mm, thickness are the square steel of 3mm, and the steel plate full weld of bracket end face " L " type seals, is soldered and surface polishes flat.
Further, it is provided with the through-hole installed for bolt on " L " shape steel plate of the bracket end face.
Further, the vertical beam is square steel, respectively has one, and and Frame Welding on two grid faces of vehicle frame.
The present invention has the advantages that：Crossbeam in anticollision device, collision-prevention device of the present invention is molded by groove profile part and angle steel welding,
The cross sectional shape of the crossbeam effectively increases the rigidity and intensity of anti-collision beam, improves battery flat Structural Crashworthiness；Secondly
It is partially opened on crossbeam there are two deformation inductdion hole, the deformation for inducing crossbeam in knockout process, crossbeam is avoided to fracture thorn
The case where wearing battery；The inclined support structure of crossbeam position can effectively disperse side impact impact force.
