Description
Technical field
The present invention relates to Truck Frame Structure more particularly to a kind of pure electric vehicle body frame structure for automotive.
Background technique
Vehicle frame is the tower structure being connected across on automobile tandem axle, is commonly called as crossbeam, is the matrix of automobile.Generally by two
Root stringer and several crossbeam compositions, mount Zhi ﹑ Qian Qiao ﹑ rear axle via Xuan and are supported on wheel.Vehicle frame must have enough strong
Degree and impact of the rigidity to bear the load of automobile and be transmitted from wheel.The function of vehicle frame is each assembly of support, connection automobile,
So that each assembly is kept relatively correct position, and bears the various load of automobile interior exterior.
It is divided at present according to the mode of body structure: bearing-type and separate frame construction, in the different form of body frame structure for automotive,
It is divided into straight frame, central frame, composite type vehicle frame again.The small-sized pure electric vehicle of the prior art is broadly divided into two kinds: one
Kind is no vehicle frame, realizes and carries by monocoque body, similar with traditional vehicle body；One is there is vehicle frame, vehicle body is non-bearing
Formula vehicle body, vehicle frame carrying.Body frame structure for automotive has defect below in the prior art: 1, the strength and stiffness of vehicle frame are small, and vehicle body can be sent out
Change shape.2, the central collision of vehicle frame, side impact effect are poor；3, for vehicle frame than cumbersome, extra repetitive structure increases its quality, manufacture
It is at high cost.Another kind is no vehicle frame, and vehicle body is monocoque body.The major defect of monocoque body: 1, due to eliminating vehicle
Frame, vibration and noise from power train and suspension will be directly transmitted to vehicle body, and compartment itself is to be easily formed to cause cavity
The resonance box of sympathetic response, therefore the riding comfort that can deteriorate significantly, for that purpose it is necessary to using a large amount of sound-proof vibration-proof material, from forming
This and quality can all increased；2, it retrofits more difficult.
Summary of the invention
The present invention is a kind of pure electric vehicle body frame structure for automotive, and crash feature is simplified on body frame structure for automotive, is done in lightweight
Go out bigger contribution, while substantially increasing the safety of the head-on crash and side collision of vehicle frame.
The technical scheme is that a kind of pure electric vehicle body frame structure for automotive, the body frame structure for automotive includes the anticollision of vehicle frame front
Structure, the vehicle frame central structure are vehicle frame left side beam inner panel, vehicle frame the right beam inner panel, are installed after mounting rail, seat before seat
Beam and battery anticollision beam assembly.The vehicle frame rear structure includes rear portion H-shaped structure, it is characterised in that: front anti-collision structure with
Rear portion H-shaped structure is connect with beam inner panel on the right of vehicle frame left side beam inner panel, vehicle frame, constitutes body frame structure for automotive.
Preferably, front anti-collision structure includes vehicle frame front anti-collision beam, vehicle frame left front girder, vehicle frame front right longitudinal beam, a floor left side
Connecting plate and front section of vehicle frame rear cross beam and one cover board of frame front cross beam before preceding connecting plate, floor are right, front section of vehicle frame rear cross beam and ground
Connecting plate constitutes " arch " structure before the left front connecting plate of plate, floor are right.
Preferably, at the intermediate position of " arch " structure of longitudinal beam connecting vehicle frame leading portion rear cross beam.
Preferably, " arch " the structure both ends of front section of vehicle frame rear cross beam and vehicle frame left side beam inner panel, vehicle frame the right beam inner panel
Connection.
Preferably, attachment beam assembly after rear portion H-shaped structure, including the left back attachment beam assembly of vehicle frame, the vehicle frame right side, vehicle frame are left back
The right floor side member of stringer, vehicle frame, vehicle frame back segment crossbeam one, vehicle frame back segment crossbeam two, vehicle frame back segment crossbeam three form.
Preferably, rear portion H-shaped structure by the left back attachment beam assembly of vehicle frame, vehicle frame it is right after at attachment beam assembly two overlap joint with
Beam inner panel connection on the right of vehicle frame left side beam inner panel, vehicle frame.
Preferably, attachment beam and right one bodily form of floor side member of vehicle frame left rear longitudinal beam, vehicle frame after the left back attachment beam of vehicle frame, vehicle frame are right
It links together at either two components.
Preferably, the cross section of vehicle frame left front girder and vehicle frame front right longitudinal beam is in " π " type, and vehicle frame left front girder and vehicle frame are right
It is connected between front longitudinal beam by several crossbeams, the cross section of the crossbeam is also in " π " type.
Preferably, the cross section of the left back attachment beam of vehicle frame is in " π " type, opening upwards, after vehicle frame left rear longitudinal beam and vehicle frame are right
The cross section of stringer is in " π " type, opening upwards, attachment beam and vehicle frame left rear longitudinal beam, vehicle frame after the left back attachment beam of vehicle frame, vehicle frame are right
Integrally formed either two components of right floor side member link together.
After adopting the above technical scheme, can effectively improve the peace of head-on crash, side collision compared to traditional body frame structure for automotive
Quan Xing, while the performance of vehicle frame anti-torsion can also be effectively improved, it ensure that the installation strength and rigidity of the vehicle of chassis system,
The performances such as ride performance, handling, passability are taken into account.The structure that above-mentioned technical proposal uses is by vehicle frame front portion structure and vehicle
Beam inner panel forms on the right of frame rear structure and vehicle frame left side beam inner panel, vehicle frame.It is designed using segmentation structure, stringer front has one
Fixed energy-absorbing function, then pass through " arch " structure of front section of vehicle frame rear cross beam, left and right side bar is transferred its energy to, energy is reached
The safety of cockpit is effectively guaranteed in the purpose of decaying, reduces front wall intrusion volume and crash acceleration to the greatest extent, gives
The maximum safe space of passenger.During side impact, collision is evenly dispersed to vehicle frame by energy by frame side member and each crossbeam
On, in transmittance process, energy is evenly arranged on entire vehicle frame middle section by cross beam support B column lower part, each crossbeam, remaining energy one
Decayed by stringer part.
