Abstract
The utility model relates to a sandwich and cross composite structure of the portion of a front floor. The sandwich and cross composite structure comprises the front floor and a side beam inner face plate. The front floor is provided with a protrusion portion opposite to the side edge inner face plate, and a ground face plate. The ground face plate is provided with a front chair beam and a rear chair beam. The lower portion of the ground face plate is provided with a front end longitudinal beam. The upper portion of the ground face plate is provided with a top frame. The top frame penetrates through the front chair beam and extends to the rear chair beam, so that the top frame and the front chair beam form a cross structure. The top frame, the ground face plate and the front end longitudinal beam form a sandwich structure. According to the composite structure, on the basis of not increasing the weight, the front floor structure which does not exist in a traditional structure and is very firm is arranged, the floor space can be effectively utilized, the structure is firmer, and the load input by front impact and side impact can be effectively dispersed; the structure can be applied to front floor structures of a car, an SUV and the like.
Description
Technical field
The utility model belongs to the technical field that automobile design is manufactured, and in particular, the utility model relates to a kind of front floor place's sandwich and cross unitized construction.
Background technology
As shown in Figure 1, the vehicle frame using when vehicle in front only has below, front floor, the vehicle frame that fore-and-aft direction stretches, this vehicle frame is in comprehensive collision, particularly when offset collision, can there is very large distortion, load passes to 4 and threshold side bar by front end longeron, energy dispersibility is limited, can make after passenger cabin row and occupant foot that large degree distortion occurs around, can increase the injury values to occupant, especially in the time of high speed, impulsive force is larger, bearing load can produce significantly distortion, in order to prevent this significantly distortion, the conventional confguration large-scale reinforcement structure of plural number that the binding site of plate and passenger cabin uses previously, increase resistance to deformation feature, improve material, the methods such as thickness approach are strengthened performance herein, these schemes can make complex structure, increase welding difficulty and gain in weight and material cost.
Utility model content
The above-mentioned technical matters existing in order to solve prior art, the purpose of this utility model is to provide a kind of front floor place's sandwich and cross unitized construction.
Front floor described in the utility model place's sandwich and cross unitized construction, comprise front floor and curb girder wainscot; Described front floor has the jut relative with described curb girder wainscot, and extends to the floor plate of described curb girder wainscot from described jut; It is characterized in that: on described floor plate, there is the cross beam of front seat and the back seat crossbeam that extend to described curb girder wainscot from described jut; Described cross beam of front seat and back seat girder space certain distance and be arranged in parallel, described cross beam of front seat is all mutually vertical with described curb girder wainscot with described jut with back seat crossbeam; The bottom of described floor plate is provided with front end longeron, at the corresponding upper frame that is provided with in the position relative with described front end longeron, the top of described floor plate; Described upper frame is through described cross beam of front seat and extend to described back seat crossbeam, makes described upper frame and described cross beam of front seat form cross structure, and described upper frame, floor plate and front end longeron form sandwich construction.
Front floor described in the utility model place's sandwich and cross unitized construction compared with prior art have following beneficial effect:
Front floor described in the utility model place's sandwich and cross unitized construction, on the basis of not gaining in weight, provide conventional confguration not available very firm front floor panel structure; The floor space that not only can effectively utilize, structure is more firm, and load is effectively disperseed, and can also effectively disperse central collision, biasing to touch the load of inputting with side impact, improves collision safety performance; Structure described in the utility model can be applied in the front floor panel structure of the vehicle such as car, SUV.
Brief description of the drawings
Fig. 1 is a kind of in prior art schematic diagram of body frame structure for automotive;
Fig. 2 is front floor place's sandwich described in embodiment 1 and the schematic diagram of cross unitized construction;
Fig. 3 is front floor place's sandwich and the cross unitized construction central collision power transmission schematic diagram described in embodiment 1;
Fig. 4 is front floor place's sandwich and the cross unitized construction side impact power transmission schematic diagram described in embodiment 1.
Detailed description of the invention
Below with reference to embodiment and accompanying drawing, described front floor place's sandwich and cross unitized construction are described in further detail.
Embodiment 1
As shown in Figure 2, front floor place's sandwich and cross unitized construction described in the present embodiment, it comprises front floor 10 and curb girder wainscot 40; Described front floor 10 has the jut 12 relative with described curb girder wainscot 40, and extends to the floor plate 14 of described curb girder wainscot from described jut 12; On described floor plate 14, there is the cross beam of front seat 30 and the back seat crossbeam 20 that extend to described curb girder wainscot 40 from described jut 12; Described cross beam of front seat 30 and back seat crossbeam 20 keep at a certain distance away and be arranged in parallel, and described cross beam of front seat 30 is all mutually vertical with described curb girder wainscot 40 with described jut 12 with back seat crossbeam 20; The bottom of described floor plate 14 is provided with front end longeron 60, at the corresponding upper frame 50 that is provided with in the position relative with described front end longeron 60, the top of described floor plate 14; Described upper frame 50 is through described cross beam of front seat 30 and extend to described back seat crossbeam 20, makes described upper frame 50 form cross structure with described cross beam of front seat 30, and described upper frame 50, floor plate 14 form sandwich construction with front end longeron 60.
Structure described in the utility model can be born the impact load that front passes over, and can prevent the distortion on front floor, and the effective crumple in vehicle front engine chamber place is also played a role, large load when it can bear 64km/h collision; Deformation behavior of vehicle body when this can significantly improve frontal collisions, improves collision safety performance.Adopt structure of the present utility model can omit the multiple large-scale reinforcement structure that in conventional confguration, passenger cabin binding site uses, be conducive to the lightweight of body structure and reduce costs.As shown in Figure 3, described cross is in conjunction with the input load that can disperse to the left and right front to pass over, and can further disperse to the left and right input load by upper frame rear end and back seat crossbeam are carried out to combination.The upper frame of being combined with cross before and after cross beam of front seat when side collision as shown in Figure 4, can disperse impact load.Structure described in the utility model can be applied in the front floor panel structure of the vehicle such as car, SUV.
For the ordinary skill in the art; specific embodiment is just exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
