Abstract
The utility model discloses a car roof. The car roof comprises a top cover body, wherein the left side and right side of the top cover body are connected with side walls of a car, and bosses which protrude upward are formed on the left side and right side of the top cover body respectively. Due to the fact that the bosses which protrude upward are formed on the left side and right side of the top cover body respectively, the bottoms of the side walls of the car are lifted by the bosses, and a space for people to get in and out is enlarged.
Description
Technical field
The utility model relates to auto body, relates in particular to a kind of car roof.
Background technology
In the Modern Car design process, although usually relate to, be the compact vehicle body, inner space but still will guarantee quite spacious, more can not affect because of the compactness of vehicle body the turnover comfort feature.
Referring to Fig. 1, in Fig. 1, the E-E position passes in and out the critical positions of comfort feature, the section drawing that Fig. 2 is E-E for personnel.Car roof 1 in Fig. 2 ' the left and right sides connect vehicle side 2 ', vehicle side 2 ' comprise gusset brace panel 21 ' and side-wall inner-plate 22 ', B
1the height of some position has determined that maximum personnel pass in and out space, for obtaining more head space, and B
1it is more high better that the some position needs.Reached minimum spatial dimension (B at body structure
1c
1spacing), in situation, if also need to obtain more head space, the designer has two kinds of ways usually:
First method: keep the roof radian, raise the height of roof, to reach, raise B
1the purpose of point. such design not only brings the increase of weight and design cost, and runs counter to the requirement of vehicle overall dimensions.
Second method: keep the roof height, reduce the roof radian, to reach, raise B
1the purpose of point. such design causes the roof radian to reduce, and roof self stiffness degradation, easily resonate in the Vehicle Driving Cycle process, produces noise, for the driver and crew in car bring puzzlement.Some automobile designers, for solving noise problem, adopt following methods to improve roof rigidity usually, reduce even to abate the noise:
1, increase the material thickness of roof
Embodiment: increase the material thickness of roof, to improve roof rigidity, eliminate resonance.
Shortcoming: gain in weight, reduce fuel economy.
2, increase clump weight in roof cross beam, change natural frequency, eliminate resonance
Embodiment: increase clump weight in roof cross beam, the material of this clump weight is metal, and general thickness, more than 10mm, otherwise can't reach the purpose that improves roof rigidity.
Shortcoming: gain in weight, reduce fuel economy; Clump weight itself and its fitting process all can bring cost to increase.
3, paste damping material at roof, change natural frequency, eliminate resonance
Embodiment: by cae analysis, find the resonance zone of roof, in this zone, paste damping material, to change local frequencies, eliminate resonance.
Shortcoming: the damping material cost is higher, increases cost; Position deviation easily occurs in fitting process, affect its performance effect; In vehicular transport/driving process, easily drop.
Therefore, be necessary to relate to a kind of car roof, can for personnel's vehicles passing in and out provides more head space, can also improve roof rigidity not improving under car load height prerequisite, solve the noise problem that the roof insufficient rigidity is brought simultaneously.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, providing a kind of can not improve under car load height prerequisite, for personnel's vehicles passing in and out provides more head space, can also improve roof rigidity, the car roof of the noise problem that solution roof insufficient rigidity is brought simultaneously.
Particularly, the technical solution of the utility model provides a kind of car roof, comprises the top cover body, and the described top cover body left and right sides connects vehicle side, and the left and right sides of described top cover body forms respectively the boss raised up.
Preferably, described boss connects the front and back of described top cover body.
Preferably, described boss is formed on the position of corresponding car door.
Preferably, described boss is 30mm with respect to the maximum height of described top cover body, and the width of described boss on left and right directions is 50mm-200mm.
After adopting technique scheme, have following beneficial effect: because the left and right sides at the top cover body forms respectively the boss raised up, boss is raised the bottom of vehicle side, thereby has promoted personnel's turnover space.
The accompanying drawing explanation
Fig. 1 is traditional vehicle side and the block diagram of car roof;
Fig. 2 is the section drawing of E-E in Fig. 1;
Fig. 3 is the utility model one embodiment and traditional car roof and the result of use comparison diagram of vehicle side;
Fig. 4 is the local structure schematic diagram of car roof in the utility model one embodiment.
The Reference numeral synopsis:
1 '---car roof 2 '---vehicle side 21 '---gusset brace panel
22 '---side-wall inner-plate
1---top cover body 2---vehicle side 11---boss
The specific embodiment
Further illustrate the specific embodiment of the present utility model below in conjunction with accompanying drawing, hereinafter identical mark refers to identical element.Said in the utility model " left side ", " right side ", 'fornt', 'back' are that orientation in the process of moving defines with respect to automobile.
As shown in Figure 3, car roof comprises top cover body 1, and top cover body 1 left and right sides connects vehicle side 2, and the left and right sides of top cover body 1 forms respectively the boss 11 raised up.The horizon that in Fig. 3, chain line A is the car roof sustained height.Because the left and right sides at top cover body 1 forms respectively the boss 11 raised up, boss 11 is raised the bottom of vehicle side 2, thereby has promoted personnel's turnover space.As can be seen from Figure 3, the nadir B of the vehicle side after improvement 2
2higher than the vehicle side 2 before improving ' nadir B
1.Therefore, the car roof in the present embodiment can for personnel's vehicles passing in and out provides more head space, can also improve roof rigidity not improving under car load height prerequisite, solves the noise problem that the roof insufficient rigidity is brought simultaneously.
Preferably, boss 11 can connect the front and back of top cover body 1.The convenient processing to car roof of this design.
Preferably, boss 11 also only is formed on the position of corresponding car door, and the bottom that only need to raise the vehicle side 2 of car door position just can meet the demand that promotes the turnover space.
Preferably, as shown in Figure 4, boss 11 is 30mm with respect to the maximum height of top cover body 1, and the width of boss 11 on left and right directions is 50mm-200mm.The height of boss 11 is higher, more can promote the bottom of vehicle side 2.Width is larger, in the situation that boss height is identical, the height that vehicle side 2 promotes is larger.
Above-described is only principle of the present utility model and preferred embodiment.It should be pointed out that for the person of ordinary skill of the art, on the basis of the utility model principle, can also make some other modification, also should be considered as protection domain of the present utility model.
