Abstract
The utility model discloses an inner plate of an automotive front hood. The inner plate comprises an inner plate body made of an aluminum alloy material, wherein a plurality of large pits are uniformly distributed in the middle of the inner plate body and are spherical pits, and the edges of the large pits are in fillet transition fit with the inner plate body; reverse small pits are formed in the bottoms of the large pits and are spherical pits, and the edges of the large pits are in fillet transition fit with the large pits. The molding manufacturability of the inner plate of the automotive front hood can be improved, and the effect of adhesion between the inner plate and an outer plate is enhanced.
Description
Technical field
The utility model relates to automobile body components, is specially a kind of car bra inner panel.
Background technology
More and more higher along with automotive light weight technology is required, the application of aluminium alloy part on automobile is also more and more.Front shroud, as the large-scale covering on vehicle body, still be take steel plate punched at present as main.Steel front shroud weight is large, is unfavorable for energy-saving and emission-reduction.Meanwhile, because steel plate hardness is large, only, by optimizing its structure, pedestrian protecting performance boost space is also less.
Front shroud adopts aluminium alloy plate punching press can realize lightweight and promotes pedestrian protecting performance.But because aluminium alloy plate ductility is not as steel plate, punch forming difficulty is large, so structure is restricted.Existing aluminium alloy car front hood back head is mainly divided into two kinds, and a kind of is on inner panel, to carry out hollow out to form skeleton shape structure, but at skeleton cross section, is unfavorable for the absorption of impulsive force, so this part effective impact-absorbing power when clashing into pedestrian.Another kind of inner panel is the pit at the some circular cone shapes of plate body middle part punching press; and by bonding at pit top gluing and front hood panel; this kind of inner panel has good pedestrian protecting performance; but because described coated face is less and smooth; therefore glue easily occurs to flow before solidifying, thereby affects the effect that is adhesively fixed between inner panel and outside plate.
Summary of the invention
The purpose of this utility model is to provide a kind of car bra inner panel, to improve inner panel moulded manufacturability, and improves the adhesive effect between inner panel and outside plate.
Car bra inner panel described in the utility model, the inner panel body that comprises aluminum alloy material, at the middle part of described inner panel body, be evenly equipped with a plurality of large pits, described large pit is sphere pit, between its edge and inner panel body, fillet is excessive, in the bottom of described large pit, be provided with reverse small rut, described small rut is sphere pit, and between its edge and large pit, fillet is excessive.
Near the posterior lateral along vehicle commander's direction of described inner panel body, be provided with reinforced rib one, and its two ends, left and right extend forward and make described reinforced rib be U-shaped, surround the large pit on described inner panel body.
On described inner panel body, offer a plurality of auxiliary holes.
Car bra inner panel described in the utility model; by the large pit of uniform sphere on inner panel body, make to form uniform larger cushion space between front shroud inner and outer plates, when being subject to pedestrian head shock; can better impact-absorbing power, thus pedestrian protecting performance improved.In addition, by small rut, as coated face, can avoid gluing to solidify front flowing, guarantee the adhesive effect of inner panel and outside plate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A section-drawing of Fig. 1;
Fig. 3 is the M place partial enlarged drawing of Fig. 2.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Car bra as shown in Figure 1, 2, comprise inner panel and outside plate 2, described inner panel comprises the inner panel body 1 of aluminum alloy material, at the middle part of inner panel body 1, be evenly equipped with 24 large pits 11, described large pit 11 is sphere pit, 1 fillet of its edge and inner panel body is excessive, in the bottom of described each large pit 11, be provided with reverse small rut 12, be that large pit 11 caves in towards outside plate direction, and small rut 12 outside plate depression dorsad, described small rut 12 is also sphere pit, and between its edge and large pit, fillet is excessive.
Described large small rut is all designed to sphere pit, and all with fillet smooth excessiveness, is beneficial to aluminum alloy material and flows, can effectively improve the punch forming process of inner panel.
In order to improve the rigidity of inner panel body 1, near the posterior lateral along vehicle commander's direction of described inner panel body, be provided with reinforced rib 13 one, and its two ends, left and right extend forward and make described reinforced rib 13 be U-shaped, surround the large pit 11 on described inner panel body.
On described inner panel body 1, offer a plurality of auxiliary holes 14, the liquid-leaking nozzle during as application.
As shown in Figure 3, flowing before inner panel and outside plate when bonding, being coated in glue 3 in the small rut 12 of described inner panel body 1, having avoided gluing to solidify, has guaranteed bonding stability.
Claims (3)
