Abstract
The utility model discloses an automotive body structure. The body structure adopts a lower longitudinal beam (4) of a front bottom plate in the longitudinal direction to connect a front longitudinal beam (2) and a back bottom plate longitudinal beam (8) as a whole, and adopts a front baffle outer beam (10) and a back bottom plate front beam (5), a back bottom plate middle beam (6) and a back plate rear beam (7) in the transversal direction to connect an engine room and a bottom plate part. The back beam is connected with a door sill (3) in the lapping part of the front bottom plate and the back bottom plate, and is strengthened by the back bottom plate front beam. With the special structure, the automotive body structure can effectively improve the bending rigidity and torsional rigidity of a whole vehicle, be favorable for improving the bearing capacity of the whole vehicle, reduce local fatigue failure caused by insufficient rigidity, and effectively improve the NVH performance of the whole vehicle. All longitudinal beams of the lower assembly are connected so as to facilitate the transmission of power and the collision energy consumption and absorption, and improve the collision safety of the whole vehicle.
Description
Technical field
The utility model relates to the automobile body-in-white structure design, especially relates to the vehicle body framework construction design of a kind of body in white bottom.
Background technology
Existing body in white bottom body framwork all is made up of longeron, back underframe longitudinal member, back front floor crossmember, back base plate after cross member and threshold under front apron, the outer crossbeam of front apron, front side member, the noseplate basically, front side member and the welding of noseplate longeron, longeron is connected by the back front floor crossmember indirectly with floor side member under the noseplate, there are following 2 deficiencies in this connection mode: 1, be unfavorable for the car load bending stiffness; 2, be unfavorable for transfer of energy, cause body distortion bigger during collision easily.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of automotive body structure at problems of the prior art, its objective is effective transmission of power in the rigidity that improves car load and the collision process, and the consumption of collision energy and absorption, finally reach the collision safety performance that improves car load.
The technical solution of the utility model is that this a kind of automotive body structure go up to adopt vertically that longeron connects as one front side member and back underframe longitudinal member under the noseplate, transversely adopt outer crossbeam of front apron and back front floor crossmember, back base plate center member and after the base plate after cross member will send out the cabin and be connected with bottom parts.
Described after cross member is connected with threshold in forward and backward base plate lap-joint, and strengthens by the back front floor crossmember.
A kind of automotive body structure with above-mentioned special construction has the following advantages:
1, improves car load bending stiffness, torsional stiffness effectively, help improving the load-carrying capacity of car load, and can reduce the local fatigue destruction that insufficient rigidity causes, improve the NVH performance of car load effectively.
2, the raising of rigidity of the vehicle can guarantee occupant space effectively, makes the passenger avoid impacting when collision as far as possible, reaches the passenger protection effect.
3, whole bottom assembly longeron couples together, and helps the transmission of power, and collision energy consumption and absorption help improving the collision safety of car load.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the utility model rear impact power is transmitted scheme drawing.
In Fig. 1-2,1: the front bumper crossbeam; 2: front side member; 3: threshold; 4: longeron under the noseplate; 5: the back front floor crossmember; 6: back base plate center member; 7: back base plate after cross member; 8: the back underframe longitudinal member; 9: post-bumper beam; 10: the outer crossbeam of front apron.
The specific embodiment
Figure 1 shows that a kind of structural representation of automotive body structure.By as can be known shown in Figure 1, this kind automotive body structure utilizes on vertically under the noseplate longeron 4 with front side member 2 and back underframe longitudinal member 8 direct connections, back underframe longitudinal member 8 is in front and back base plate lap-joint and threshold 3 couples together and pass through 5 reinforcements of back front floor crossmember, utilizing the outer crossbeam 10 of front apron will send out the cabin with back front floor crossmember 5, back base plate center member 6 and back base plate after cross member 7 in the horizontal is connected with bottom parts, and play carries left, right vertical beam effect, reduce reversing of bottom vehicle body.
This body framwork can improve car load bending stiffness, torsional stiffness effectively, helps improving the load-carrying capacity of car load, and can reduce the local fatigue destruction that insufficient rigidity causes.
Fig. 2 is that a kind of automotive body structure rear impact power is transmitted scheme drawing.As shown in Figure 2, when body framwork post-bumper beam 9 bumps,, can effectively collision energy be passed to the gusset part, reduce the application force that passes to the occupant, help collision safety because of back underframe longitudinal member 8 is connected with threshold 3.
Same, when body framwork front bumper crossbeam 1 bumps, because of longeron under the noseplate 4 is connected front side member 2 with back underframe longitudinal member 8, transferred to the back bottom parts during load input reliably, and can convert collision energy to kinetic energy, can reduce body distortion effectively, correspondingly reduce the human injury, improve the collision performance of car load.
After being subjected to vibrational excitation, vehicle body can produce the complex form of overall bending vibrattion, torsion oscillations or various vibrations of vehicle body, also can cause the local vibration of plate simultaneously, produce the mechanicalness noise, and reasonably rigidity can be improved the noise that is produced by body structure preferably, improves the NVH performance of car load.
Under the situations such as vehicle rollover, the raising of rigidity of the vehicle can guarantee occupant space effectively, makes the passenger avoid impacting when collision as far as possible, reaches the passenger protection effect, helps to improve the safety performance of vehicle.
Claims (2)
