Abstract
The utility model relates to a novel automobile rear bumper structure which comprises a rear end plate and a bumper arranged on the rear end plate; and the bumper comprises an energy absorbing area with parts protruding, and a connected area connected with the energy absorbing area and arranged on the rear end plate. Based on the common steel material, the utility model optimizes the structure, so that the structure is easy to form, so as to reduce the weight and provide convenience for installation. The novel automobile rear bumper structure greatly reduces the cost from material selection, number of parts, part manufacturing process, installation and other links. In addition, the utility model can also well meet the requirements of relevant national regulations and industrial standards (GB17354), well protects the tail structure of a car, greatly reduces the production cost, and is very practical.
Description
Technical field
The utility model relates to a kind of crash bar mechanism, particularly relates to a kind of later-model automobile Grard Assy structure.
Background technology
In recent years, along with the fast development of auto-domain, market competition is fierce day by day, and characteristics such as low-cost, easy enforcement, high quality, lightweight more and more are subject to people's attention and favor.Present Grard Assy divides from material plastics, aluminium and made of iron.The structure of plastics Grard Assy as shown in Figure 1, equal more complicated: part is many, the molding procedure complexity, bolted connection is installed to the floor side member more loaded down with trivial details, main is the cost height; And the aluminum Grard Assy is as shown in Figure 2, and its weight reduces to some extent, but extrusion forming mode, bolted connection to floor side member and cost in price all than higher, so, only be used for above the luxury car usually; Grard Assy made of iron in recent years more and more is applied on the various vehicles because its have the cost of raw material low, not only economy but also special quality characteristics such as processing technology is simple, easy for installation.
The utility model content
The purpose of this utility model be to provide a kind of economical and practical, when vehicle afterbody generation low speed collision, can protect bonnet or lifting door zone, guarantee that vehicle is not subjected to the later-model automobile Grard Assy structure of major injury.
For achieving the above object, the utility model is taked following design plan:
A kind of later-model automobile Grard Assy structure comprises lower back panel and is installed in crash bar on the described lower back panel, and described crash bar comprises to the energy-absorbing zone of small part projection also can be installed in join domain on the described lower back panel with linking to each other with described energy-absorbing zone.
Preferably, described energy-absorbing zone and described join domain are made into integration.Further, perpendicular to described Grard Assy axis of no-feathering to the cross section on, the area in described energy-absorbing zone is less than the area of described join domain.
Preferably, the longitudinal cross-section in described energy-absorbing zone is several fonts or M type or their combination.
The utility model has the advantages that: the utility model is on the basis of ordinary steel material, optimizes structure, makes it to be easy to moulding and expendable weight, is convenient to install.All greatly reduce cost from each links such as the manufacturing process of the quantity of selection, part, part and installations.And the utility model also is well positioned to meet the requirement of national relevant laws and regulations and industry standard (GB17354), protects the tail of body structure well.The utility model can reduce production costs widely, and is very practical.
Description of drawings
Fig. 1 and Fig. 2 are the structural representation of Grard Assy in the prior art;
Fig. 3 is a structural representation of the present utility model;
Fig. 4 is the birds-eye view of structure shown in Figure 3;
Fig. 5 and Fig. 6 are the schematic cross-section of the utility model crash-proof pole structure preferred embodiment.
The specific embodiment
Referring to Fig. 3～Fig. 6, the preferred embodiment of a kind of later-model automobile Grard Assy structure of the utility model shown in it, comprise lower back panel 3 and be installed in crash bar 10 on the described lower back panel 3, described lower back panel 3 is installed on the vehicle body, wherein, described crash bar 10 comprises to the energy-absorbing of small part projection zone 1 and also can be installed in join domain 2 on the described lower back panel 3 with linking to each other with described energy-absorbing zone 1.In the present embodiment, as shown in Figure 3, be provided with the energy-absorbing zone 1 of projection at the middle part of described crash bar 10.Preferably, described energy-absorbing zone 1 and described join domain 2 are made into integration, and can be common structure of steel product.
As shown in Figure 4, perpendicular to described Grard Assy axis of no-feathering to the cross section on, the area in described energy-absorbing zone 1 is less than the area of described join domain 2, this kind structure helps absorbing owing to impact the energy that produces more.
The longitudinal cross-section in described energy-absorbing of the present utility model zone 1 is several fonts (as shown in Figure 5), or M type (as shown in Figure 6) or their combination.
More specifically, because selection of the present utility model is prevailing steel, so, aspect raw MAT'L, be very easy to buying.
In addition, the utility model is structurally very simple: the integral body of crash bar 10 has only a part, as Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6.Again as shown in Figure 3 and Figure 4, the centre portion in the energy-absorbing zone 1 of the utility model projection is the join domain 2 that arch and cross section are slightly less than both sides, thus can be so that the distortion energy-absorbing.And a kind of embodiment in 1 cross section, the utility model energy-absorbing zone is similar " several " font or " M " type structure, preferably, can increase reinforced rib in position; Such structure has significantly reduced the number of part and the complexity of part.
Part of the present utility model is directly punch forming all, and mounting means is for directly being welded on the lower back panel.Do not have a plurality of bolts to need to connect, this has also simplified manufacturing and mounting process process greatly.
In application, when low speed collision or when touching the arcuate part in energy-absorbing zone 1, the energy-absorbing zone of Grard Assy will begin distortion, absorb owing to impact the energy that produces.We find out that arcuate part has cooresponding deformation space from figure, as long as the deflection of arcuate part in the design-calculated scope, just can not damage protected parts.Grard Assy has just protected bonnet or lifting door to be without prejudice thus, even behind low speed collision, bonnet or lifting door also can normally be opened (promptly meeting standard GB 17354 regulations).
Obviously, those of ordinary skill in the art can constitute various types of anticollision mechanisms with a kind of later-model automobile Grard Assy structure of the present utility model.
The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the utility model scope; can also make various variations and modification; therefore all technical schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
