Abstract
The invention relates to a vehicle front cover, which comprises cover plate (1) and supports fixed on the inner surface of cover plate, wherein said support is inner plate (1) made from aluminum alloy sheet, whose lower surface facing the chamber has several upwards concaves (3) to form platforms (5); the inner plate (2) is connected to the chamber plate (1) at the platforms (5). The invention has low cost and high efficiency.
Description
Technical field
The present invention relates to the especially preceding hatchcover of car of automobile, but hatchcover before the light metal of the various automobiles of specifically a kind of lightweight.
Background technology
Automobile front chamber lid is the part of vehicle structure, is in the same place by two hinges and front deck cover lock and body contact, plays the effect that parts such as protecting engine assembly are not subjected to rainwater and harsh environment infringement.Preceding hatchcover normally is stamped to form by steel plate; because the vertical and horizontal span of preceding hatchcover is bigger; the hatchcover surface needs certain rigidity; and under the situation of automobile generation head-on crash, also need to play the work of buffering with the protection occupant; therefore; proof strength again in the time of for expendable weight; present preceding hatchcover is usually by hatchway cover be fixed on the hatchway cover lower surface strut member of its reinforcing is formed; this hatchway cover and strut member are to be processed by the steel plate that two thickness are generally 0.7-0.9MM; one is processed into hatchway cover; another piece is made the steel structure strut member of frame-type usually by punching press, strut member is connected with hatchway cover by welding.The strut member of this spline structure produces the polylith waste material in punching course, reduced the part material degree of utilization, makes steel plate materials degree of utilization only about 54%; Another shortcoming is that weight ratio is bigger, and the preceding hatchcover weight of whole steel structure reaches 14 kilograms, deviates from mutually with the lightweight of present car industry requirement, and weight will increase consumption of fuel greatly, increases the influence to environment.
Summary of the invention
To be solved by this invention is the low and heavier problem of weight of the used strut member stock utilization of above-mentioned automobile front chamber lid, the invention provides a kind of automobile front chamber lid, by the strut member that adopts the lightweight material to make, not only can improve the degree of utilization of material, can also reduce the weight of automobile front chamber lid, play energy-conserving action.
Solution of the present invention is: automobile front chamber lid, comprise hatchway cover and be fixed on the strut member of hatchway cover inside face, the inner panel that described strut member is made by light metal sheet material, the downside surface of inner panel promptly is provided with some depressions upward and forms the flat-bed pit of projection at uper side surface towards the surface in cabin, inner panel is connected with hatchway cover at the platform place.
Inner panel as strut member is connected with hatchway cover at the platform place of pit bottom, and therefore, the power that acts on the hatchway cover is delivered on the inner panel by pocket wall, by the pit quantity selecting to be fit to distribute and can improve dent resistance to hatchway cover.
Inner panel material of the present invention is most economical with aluminum alloy materials, and processing is the easiest, can utilize its good prolonging to press performance with the pit punch forming on the inner panel.
In addition, can pass through adhesive-bonded joint between aluminum alloy and the steel plate, and bind strength is higher, therefore inner panel of the present invention is bonding by viscose glue and hatchway cover at the platform place, and the edge of inner panel is fastened by flange by hatchway cover and reinforces.Can also improve work efficiency by bonding.
The present invention is provided with the reinforced rib that is connected between the adjacent pit sidewall of length over ends of body direction, can improve the support strength of hatchway cover in the length over ends of body direction, when car body the place ahead bumps, can play a protective role to the occupant.This reinforced rib can be the groove walls that forms at the inner panel uper side surface by punch forming.
In addition, between the adjacent pocket wall of width over sides of car body direction, also the reinforced rib that is connected can be set, on inner panel, form network architecture, make support strength improve.
The present invention adopts the light metal material aluminum alloy plate materials to substitute original steel plate and makes strut member, on inner panel, be easy to form the connection platform of projection by Sheet Metal Forming Technology, and between pit, form interconnective reinforcing rib structure, not only improve the dent resistance of hatchway cover, material therefor is almost not loss in the course of processing, the degree of utilization of material is high, and the cost of material also lowers significantly.And processing easily, and the forming process of employing is well suited for industrialized mass, the production efficiency height.Inner panel is that the aluminum alloy plate materials of 0.9-1.2mm is an example to adopt thickness, and the steel structure that weight ratio is traditional has alleviated more than 30%, can reduce the weight of car load, is greatly improved aspect energy-conserving and environment-protective.
Description of drawings
Fig. 1 is the upward view of automobile front chamber lid of the present invention.
Fig. 2 is along A-A line section-drawing among Fig. 1.
Among the above-mentioned figure, 1, hatchway cover, 2, inner panel, 3, pit, 4, reinforced rib, 5, platform.
The specific embodiment
As shown in Figure 1 and Figure 2, inner panel 2 its downside surfaces of being made by aluminum alloy plate materials promptly are provided with some (promptly in Fig. 2 direction) from top to bottom upward depressions and form the pit 3 of the platform 5 of projection at uper side surface towards the surface of engine compartment, this pit is through stamping forming, be bowl-shape, near coal-mine is circular, and near coal-mine diameter is greater than hole end diameter.Certainly pit also can be hexagon or other any suitable shape.Pit is looked the pit diameter size number row is set on the length over ends of body direction, establish three rows in this example, adjacent row's pit is staggered, be provided with reinforced rib 4 between the pocket wall of front and rear row, this reinforced rib is at the inner panel downside surface groove that forms of (promptly in Fig. 2 direction) from top to bottom punching press promptly towards the surface in cabin upward.Also the reinforced rib (not shown) can be set between the adjacent pit of same row.
Before about hatchcover the back afterbody be that the brace panel (not shown) can be welded in top and hinged place among Fig. 1, to improve preceding hatchcover and hinged intensity.
