The whole impact resistance for enough enhancing cover, to be effectively increased safety.
In addition, the utility model embodiment provide front engine cover of car and apply its automobile, using carbon fiber composite
Expect material, relatively cover before steel material, it can 50% or more effective loss of weight；The structure design of optimization, compared to steel material
Preceding cover, largely improves collision performance and dent resistance；Efficiently solve the interior template face of cover before steel material excessively
The problem complicated, manufacture difficulty is big, of high cost.
Embodiment one：
Fig. 4 is the inside structure schematic diagram for the 4th kind of front engine cover of car that the utility model embodiment provides.
As Figure 1-Figure 4, the front engine cover of car that the utility model embodiment one provides, including：Cover outside plate 1, and
Cover inner panel 2, cover inner panel 2 are adhered to side of the cover outside plate 1 towards body frame.
In the present embodiment one, cover outside plate 1 and cover inner panel 2 are all made of carbon fibre composite and are made, individually solid
It is bonded to one after chemical conversion type；Herein it should be added that, cover outside plate 1 and cover inner panel 2 and non-fully fitting attachment
Together, but there are part curve form matching areas 3, as shown in figure 4, at the curve form matching area 3, outside cover
Plate 1 bonds together with cover inner panel 2, remaining part not being bonded, and cavity is formed between cover outside plate 1 and cover inner panel 2, with
Ensure that front engine cover of car has enough rigidity.
Since carbon fibre composite manufacturing tolerance is big, to reduce the bonding difficulty of cover outside plate 1 and cover inner panel 2,
Meet between inner and outer plates under the premise of there are enough cohesive forces, can reduce as far as possible viscous between cover outside plate 1 and cover inner panel 2
Junction is accumulated；Specifically, the distribution of bonding region and size can be optimized through CAE analysis.
As shown in figure 4, cover inner panel 2 is formed at the circumference of corresponding front engine cover of car, at the position by front end
With the curve form matching area 3 of cover outside plate 1, the i.e. bonding region of cover inner panel 2 and cover outside plate 1.In addition to this, automobile
There is outburst area, cover inner panel 2, which has from the outburst area, extends to front engine cover of car at left and right sides of the rear end of preceding cover
The rising zone of front end forms the gap of perforation, to ensure automobile in the rising zone between cover outside plate 1 and cover inner panel 2
The rigidity of preceding cover in the longitudinal direction, and the section in the gap formed between cover outside plate 1 and cover inner panel 2 can be calculated through CAE
It optimizes.
As Figure 1-Figure 4, it is contemplated that the factors such as loss of weight demand and collision safety, cover inner panel 2 are formed with weakening region
Hollow structure may be used in domain 20, the atenuator region 20；Preferably, cover inner panel 2 the central region of front engine cover of car can be with
It is formed with atenuator region 20 at three.Not only the weight of front engine cover of car can as a result, reduced, but also before automobile being reduced
Local stiffness of the cover in corresponding front engine cover of car at front end area, to front engine cover of car be made to be easy in collision
Bending enters the risk of crew module to reduce front engine cover of car in collision, and then reduces front engine cover of car intrusion cockpit
Risk.
Atenuator region 20 can be obtained by implementing local hollow out to cover inner panel 2, but be hollowed out to cover inner panel 2
Although processing can absorb energy when colliding, the rigidity of front engine cover of car is also reduced simultaneously, dent resistance can become
Difference, in order to solve this problem, cover inner panel 2 are formed with the rigidity reinforced structure 21 around atenuator region 20.
Specifically, as shown in Fig. 2, three atenuator regions 20 are arranged side by side in the width direction of front engine cover of car；Accordingly
Ground, rigidity reinforced structure 21 may include the first rib 211 and the second rib 212.
Further, the first rib 211 is located at four sides of three atenuator regions 20, plays intensity to cover inner panel 2 and carries
The effect risen, that is, the first rib 211 can be located at the peripheral regions of front engine cover of car, to improve the surrounding area of front engine cover of car
The rigidity in domain, and buckle is installed before can be also used for stationary cover；When practical set, installation buckle can pass through example before cover
Such as screw connector attaches to the first rib 211.
Second rib 212 can be two, and two the second ribs 212 can extend and in vapour in the first rib 211
It is alternately arranged with three atenuator regions 20 in the width direction of Chinese herbaceous peony cover.
To sum up, cover outside plate 1 remains to all obtain the support from cover inner panel 2 at three atenuator regions 20.
In addition, in order to be conducive to carbon fibre composite manufacture, the section of rigidity reinforced structure 21 can design for shape for hat,
The dent resistance of front engine cover of car can be greatly promoted in this way.
Further, cover inner panel 2 can also be formed with boss 22, which is located at the rear end of front engine cover of car,
For fixed block after connection.As shown in figure 3, boss 22 can carry mounting hole, it can be for example, by screw from then fixed block
Equal fixing pieces pass through mounting hole to be fixed on boss 22.
It, can be in the inner surface additional of boss 22 in the present embodiment one since mounting hole can reduce the rigidity of boss 22
The second reinforcement laying is connect, to realize connection reinforcement to boss 22.
In addition, it is contemplated that volume production needs, above-mentioned cover outside plate 1 and cover inner panel 2 may be used high pressure RTM techniques at
Type.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
