Abstract
The utility model relates to a composite construction bonnet that gathers dicyclopentadiene material, including outer covering piece and interior reinforcement, the interior side surface of outer covering piece is provided with the recess, the outside of interior reinforcement is provided with the boss, there is the clearance fit relation between recess and the boss, use glue to be connected between outer covering piece and the interior reinforcement, so the compound bonnet of structure has light in weight, and the outward appearance molding is freer, advantages such as surface quality height, and the specially adapted has lightweight requirement new energy automobile.
Description
Technical field
The utility model relates to a kind of composite construction bonnet, particularly relates to a kind of composite construction bonnet of dicyclopentadiene material.
Background technology
Existing automobile engine cover uses cold-rolled steel sheet to process by Sheet Metal Forming Technology conventionally, in order to reach the specification standards of integral rigidity, when design, can adopt concavo-convex geometry and turnup structure and inner side edge riveting to strengthen the measures such as structure structural member, one of this fault of construction is Heavy Weight, and energy consumption increases. In recent years, along with the eruptive growth of new-energy automobile, automotive dead weight has been proposed to requirement, because be directly connected to endurance distance problem, and endurance distance is a bottleneck of new-energy automobile development, and the way that prior art is dealt with problems has two, the one, increase battery capacity, the 2nd, reduce automotive dead weight, by contrast, the latter is more having superiority aspect technology, cost. The density of dicyclopentadiene material is approximately 1/8 of steel plate, can use mould once-forming, surface quality surpasses steel plate, and material itself has high cold-resistant heat, high impact properties, UV resistant radiation, stable mechanical property, passes through cae analysis, ensureing under the prerequisite that serviceability is suitable, weight can decline 40%, and lightweight is for new-energy automobile, very meaningful.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of composite construction bonnet of light-weighted dicyclopentadiene material.
The utility model solves the technical scheme that its technical problem adopts: the composite construction bonnet that a kind of dicyclopentadiene material is provided, comprise outer covering piece and interior reinforcement, the inner surface of described outer covering piece is provided with groove, the arranged outside of described interior reinforcement has boss, between described groove and boss, there is clearance fit relationship, between described outer covering piece and interior reinforcement, use glue to be connected.
Produce corresponding mould by the shape of the outer covering piece of described composite construction bonnet and interior reinforcement, on reaction injection molding machine, by dicyclopentadiene material once-forming.
Beneficial effect
Owing to having adopted above-mentioned technical scheme, the utility model compared with prior art, there is following advantage and good effect: the utility model is by splitting into bonnet part outer covering piece and interior reinforcement, outer covering piece is a curved surface part that waits wall thickness, inner side does not have structure except groove, piece surface does not produce stress defect, therefore, the appearance surfaces being shaped out can reach A level curved surface standard, meet the requirement of automobile industry, compare metal forming curved surface more freely smooth, the purpose of design of groove and boss is to allow outer covering piece and interior reinforcement accurately locate. the effect of interior reinforcement has two, the one, form and be rigidly connected by glue and outer covering piece, thereby play the integral rigidity that strengthens composite construction bonnet, the 2nd, bear all force structures, be distributed to equably outer covering piece on the whole by interior reinforcement by stressed, thereby avoid outer covering piece to produce distortion because of local pressure, final realization with steel plate relatively in the constant situation of performance, the practical effect of weight reducing 40%. reaction injection molding technique makes large-sized automobile engine cover shaping have feasibility.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, further set forth the utility model, should understand, these embodiment are only not used in restriction scope of the present utility model for the utility model is described, in addition should understand, after having read the content of the utility model instruction, those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, embodiment of the present utility model relates to a kind of composite construction bonnet of dicyclopentadiene material, comprise outer covering piece 1 and interior reinforcement 2, outer covering piece 1 inner surface is provided with groove A, the arranged outside of interior reinforcement 2 has boss B, groove A and boss B form and coordinate positioning relation, glue coating 3 between outer covering piece and interior reinforcement, on special equipment, outer covering piece and interior reinforcement compressed and keep certain hour, make glue dries, complete being rigidly connected between interior outer member.
Claims (1)
1. the composite construction bonnet of a dicyclopentadiene material, comprise outer covering piece and interior reinforcement, it is characterized in that, the inner surface of described outer covering piece is provided with groove, the arranged outside of described interior reinforcement has boss, between described groove and boss, have clearance fit relationship, between described outer covering piece and interior reinforcement, use glue to be connected, the material of described outer covering piece and interior reinforcement is polydicyclopentadiene.
