Abstract
The utility model discloses an automobile collision protective structure, comprising a frame cross beam and a collision diagonal bracing, wherein one end of the collision diagonal bracing is connected with the frame cross beam; the frame cross beam is fixedly connected on a frame longitudinal beam, and the other end of the collision diagonal bracing is fixedly connected on the frame longitudinal beam. In the automobile collision protective structure, by adding the collision diagonal bracing, the collision protective performance of the automobile frame can be promoted, so as to protect a driver and passengers well; furthermore, the automobile collision protective structure is connected on the frame longitudinal beam of the automobile by a bolt, so as to be convenient for assembly, disassembly or replacement.
Description
Technical field
The utility model belongs to the automobile chassis frame technical field, and specifically, the utility model relates to a kind of automobile chassis frame crash protection structure.
Background technology
In the crash protection structure of automobile ladder type frame, what use at present mainly is energy-absorbing girder construction, spring attenuating structure, rubber buffering energy-absorbing structure, air bag attenuating structure, front bumper protection class formation or the like.These structures mainly are exactly to utilize the buffering energy-absorbing performance of structure itself, when collision happens, reach control fireproof brickwork intrusion amount, thereby protection chaufeur and passenger's life security, but this structure does not often have good protective action, the crash protection effect is undesirable, and lower grade of collision; And above-described crash protection structure all is non-removable, is not easy to dismounting maintenance or replacing.
The utility model content
The technical problems to be solved in the utility model is to realize a kind of detouchable auto against protection structure, not only has good crash protection effect, and is convenient to dismounting maintenance or replacing.
To achieve these goals, the technical solution adopted in the utility model is: a kind of auto against protection structure comprises that a cross member of frame and an end are connected in the collision diagonal brace on the described cross member of frame; Described cross member of frame is fastenedly connected on chassis side rail, and the described collision diagonal brace other end is fastenedly connected on chassis side rail.
Described collision diagonal brace has two, is symmetrically welded on described cross member of frame; This collision diagonal brace is a strip, and the middle part has step and arc transition is arranged.
Be provided with overarm brace at described cross member of frame and chassis side rail junction, described cross member of frame is by being bolted on this overarm brace; Be provided with the diagonal brace support at described collision diagonal brace and chassis side rail junction, described collision diagonal brace is by being bolted on this diagonal brace support.
Described collision diagonal brace at connection location on the cross member of frame between two chassis side raiies.
Described overarm brace and diagonal brace support all are welded on the chassis side rail.
Advantage of the present utility model is to increase the collision diagonal brace, can promote the crash protection performance of automobile chassis frame, can play a very good protection to chaufeur and passenger; And this crash protection structure by bolted connection on the automobile chassis frame longeron, be convenient to dismounting maintenance or change.
Description of drawings
Below the content of each width of cloth accompanying drawing expression of the utility model specification sheets and the mark among the figure are made brief description:
Fig. 1 is the utility model structural representation;
Fig. 2 is collision diagonal brace structural representation.
Mark among the above-mentioned figure is: 1, diagonal brace support; 2, collision diagonal brace; 3, cross member of frame; 4, overarm brace; 5, chassis side rail; 6, bolt; 21, diagonal brace crossbeam coupling end; 22, diagonal brace support coupling end.
The specific embodiment
Contrast accompanying drawing below, by description to embodiment, effect and principle of work, the manufacturing process of mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
As shown in Figure 1 and Figure 2, a kind of auto against protection of the utility model structure comprises that a cross member of frame 3 and an end are connected in the collision diagonal brace 2 on the cross member of frame 3; This cross member of frame 3 is fastenedly connected on chassis side rail 5, and described collision diagonal brace 2 other ends are fastenedly connected on chassis side rail 5.
Described collision diagonal brace 2 has two, is symmetrical in vehicle centerline and is welded on the described cross member of frame 3; This collision diagonal brace 2 is a strip, comprises diagonal brace crossbeam coupling end 21 and diagonal brace support coupling end 22, and the middle part has step and arc transition is arranged.Described collision diagonal brace 2 between two chassis side raiies 5, constitutes gusseted at connection location on the cross member of frame 3 separately.This structure can be when automobile bumps; make the automobile crumple so far just stop crumple in the structure place; make fireproof brickwork intrusion amount less; and can be within the receptible zone of reasonableness of chaufeur and passenger institute Acceleration Control; so just can promote the whole crash protection performance of automobile, greatly protect chaufeur and passenger's safety.
In order to have promoted the coupling stiffness of whole crash protection structure, between described cross member of frame 3 and chassis side rail 5, be provided with overarm brace 4, described cross member of frame 3 two ends respectively are fixed on this overarm brace 4 by 4 bolts 6; Be provided with diagonal brace support 1 at described collision diagonal brace 2 with chassis side rail 5 junctions, described two collision diagonal braces 2 respectively are fixed on this diagonal brace support 1 by 4 bolts 6.Described overarm brace 4 and diagonal brace support 1 all are welded on the chassis side rail 5.So just make that the crash protection structure is detachable, be convenient to maintenance or replacing, improved car load NVH performance simultaneously again.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
