Description
Technical field
This utility model relates to technical field of automobile, the most reinforced bonnet.
Background technology
Raising day by day along with people's living standard; automobile come into more and more the common people other; the owning amount of passenger car sharply increases; vehicle driving safety problem becomes a major issue of harmonious society, and a main research and development problem of world today's development of automobile is exactly to protect pedestrian and the safety of passengers inside the car to greatest extent.
But, along with automobile gets more and more, the automobile safety accident of appearance also gets more and more, and the intensity of the bonnet of electromotor is the important indicator of impact safety, and existing bonnet is thin board type cavity structure, and its intensity is low, and bonnet is easily deformed.It addition, during engine rotation, in the incoming driver's cabin of roar sent, affect Ride Quality.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of fill convenient and that intensity is high reinforced bonnet.
The purpose of this utility model is achieved through the following technical solutions: reinforced bonnet, including engine hood outer panel, bonnet inner panel and filler, the edge of engine hood outer panel is provided with kink, kink extends along the inner side of engine hood outer panel, the edge card of bonnet inner panel is combined between engine hood outer panel and kink, engine hood outer panel forms closed cavity with bonnet inner panel, is filled with filler in described closed cavity.
Further, the surface of described bonnet inner panel has at least one hand-hole.
Further, described hand-hole has two, and hand-hole is arranged at the front portion of bonnet inner panel, and another hand-hole is arranged at the rear portion of bonnet inner panel.
Further, described filler is cranny filler of polyurethane foam.
This utility model has the advantage that
1, engine hood outer panel is connected by filler with bonnet inner panel so that engine hood outer panel has the support of bonnet inner panel, has cushioning effect and the sound insulation vibration isolation effect of filler simultaneously.
2, on bonnet inner panel, have hand-hole, inject filler to closed cavity respectively by hand-hole front and back, it is achieved closed cavity injects more tight, and intensity is high, and fills conveniently.
3, filler is cranny filler of polyurethane foam, and it has high-foaming, the characteristic of resisted shrinkage, and after solidification, temperature resistant range is-30～+90 DEG C, and expansion rate is at about 80 times.

Fig. 2 is structure for amplifying schematic diagram at A in Fig. 1；
Fig. 3 is structure for amplifying schematic diagram at B in Fig. 1；
In figure: 1-engine hood outer panel, 2-bonnet inner panel, 3-filler, 4-kink, 5-hand-hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in figures 1 and 3, reinforced bonnet, including engine hood outer panel 1, bonnet inner panel 2 and filler 3, the edge of engine hood outer panel 1 is provided with kink 4, kink 4 extends along the inner side of engine hood outer panel 1, the edge card of bonnet inner panel 2 is combined between engine hood outer panel 1 and kink 4, and engine hood outer panel 1 and bonnet inner panel 2 form closed cavity, are filled with filler 3 in described closed cavity.
As in figure 2 it is shown, have at least one hand-hole 5 on the surface of described bonnet inner panel 2, in the closed cavity between engine hood outer panel 1 and bonnet inner panel 2, inject filler 3 by hand-hole 5, convenient and swift.
Further, described hand-hole 5 has two, and hand-hole 5 is arranged at the front portion of bonnet inner panel 2, and another hand-hole 5 is arranged at the rear portion of bonnet inner panel 2.
As preferably, described filler 3 is cranny filler of polyurethane foam, and it has high-foaming, the characteristic of resisted shrinkage, and after solidification, temperature resistant range is-30～+90 DEG C, and expansion rate is at about 80 times.
Work process of the present utility model is as follows: first block the hand-hole 5 at bonnet inner panel 2 rear portion, filler 3 is injected by the hand-hole 5 of bonnet inner panel 2 front portion, when filler 3 is full of the closed cavity front portion between engine hood outer panel 1 and bonnet inner panel 2, block the hand-hole 5 of front portion, filler 3 is injected again by the hand-hole 5 at bonnet inner panel 2 rear portion, when the closed cavity rear portion that filler 3 is full of between engine hood outer panel 1 and bonnet inner panel 2 blocks the hand-hole 5 at rear portion again, 8 hours are treated after injection, solidification is removed plug and clears up surface, engine hood outer panel 1 is connected by filler 3 with bonnet inner panel 2, engine hood outer panel 1 is made to have the support of bonnet inner panel 2, there are cushioning effect and the sound insulation vibration isolation effect of filler 3 simultaneously.
