Manned vehicle hard instrument carrier panel upper cover plate assembly
Technical field
The utility model relates to hard manned vehicle instrument carrier panel, specifically, relates to a kind of all-in-one-piece hard instrument carrier panel upper cover plate assembly.
Background technology
Along with being showing improvement or progress day by day of automotive technology, many-sided requirements such as cost savingsization, technology simplification, handsome in appearanceization have been proposed for the structure design of automotive trim.At present, the prolate the brim of a hat type appearance and modeling of instrument carrier panel upper cover plate enjoys favor because of its individual character is graceful.At present, this class upper cover plate all adopts hard skeleton to cover soft material formation outward.Yet for the hard instrument carrier panel, soft material cover type instrument carrier panel has shortcomings such as material cost costliness, process structure complexity, Fabrication procedure be various.
According to the prolate structure of existing hard facia design method realization upper cover plate, need be assembled by top panel, following cover cap, support frame and fastener.This kind structure causes following drawback: can form long and narrow, the showy slit that cooperates between top panel and following cover cap, the slit parallelism is relatively poor.Top panel is difficult to arrange strong draw bail with the prolate space that following cover cap surrounds, and has a strong impact on air bag explosion and head impact performance.
At present, do not find that all-in-one-piece hard upper cover plate structure occurs.
The utility model content
The purpose of this utility model provides a kind of manned vehicle hard instrument carrier panel upper cover plate assembly, and solution prolate type upper cover plate assembly is difficult to the technical matters with the hard structure realization.
The utility model is achieved through the following technical solutions:
A kind of manned vehicle hard instrument carrier panel upper cover plate assembly is fixedly installed on the instrument board framework body, and described upper cover plate is flat slab construction, and has the all-in-one-piece moulding of the brim of a hat type flange at the occupant side edge.
Arrange some U type reinforced ribs in the inner chamber of the brim of a hat type flange of described upper cover plate.
The outward flange of described upper cover plate connects with instrument carrier panel body skeletal fixation by fastener.The slab construction of described upper cover plate connects with the body skeleton by assembling guide finger and screw.Described upper cover plate also comprises the bottom of dangling from the edge of the brim of a hat type flange downwards, and this bottom is fixedly connected on instrument carrier panel body skeleton.
Described upper cover plate also is provided with left demist air port and right demist air port, and the air bag reinforced bulkhead.
The utility model is cancelled the labyrinth and the connection in split type the brim of a hat zone owing to adopt all-in-one-piece upper cover plate, makes parts connect failure risk and reduces, and structural strength significantly strengthens simultaneously; Because adopting single part to be aided with U type reinforced rib group, the upper cover plate brim structure constitutes, so energy-absorbing effect is better, head bumps performance and significantly improves; And simplified manufacturing process, cost significantly reduces.

Fig. 2 is an integral type hard instrument carrier panel upper cover plate assembly upward view of the present utility model;
Fig. 3 is an integral type hard instrument carrier panel upper cover plate assembly subssembly drawing of the present utility model; Number in the figure explanation: 1-hard upper cover plate, 2-body skeleton, 3-slab construction, 4-upper cover plate U type reinforced rib group, 5-upper cover plate the brim of a hat type structure, 6-set screws, flange zone under the 7-upper cover plate, demist air port, a 8-left side, 9-upper cover plate edge set screws, the right demist of 10-air port, the 11-set screws, 12-assembles guide finger, 13-body skeleton projecting tendon group, 14-air bag reinforced bulkhead.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
As Fig. 1, Fig. 2, shown in Figure 3, the moulding of the one that the manned vehicle hard instrument carrier panel upper cover plate assembly that present embodiment relates to, described hard upper cover plate 1 are made up of PP or PC/ABS; It has flat basically slab construction 3, and has the brim of a hat type flange 5 at its whole occupant side edge.
Described upper cover plate 1 is fixedly installed on the body skeleton 2, wherein: described hard upper cover plate 1 all outward flanges adopt set screws 9 to connect with body skeleton 2; The slab construction 3 of hard upper cover plate 1 adopts assembling guide finger 12, set screws 11 to connect with body skeleton 2; Described upper cover plate 1 also comprises the bottom 7 of dangling from the edge of the brim of a hat type flange 5 downwards, and this bottom connects with the body skeleton by tightening screw group 6.
Arrange upper cover plate U type reinforced rib group 4 in the inner chamber of the brim of a hat type flange 5 of described hard upper cover plate 1, hard upper cover plate 1 other zone is supported by the end face body skeleton projecting tendon group 13 of body skeleton 2.
Described upper cover plate assembly also comprises air bag reinforced bulkhead 14, left demist air port 8, right demist air port 9, and described air bag reinforced bulkhead 14 is fixed with friction welding with the copilot side of upper cover plate bottom, and adopts screw attachment in headstock direction and body skeleton 2; Described left demist air port 8 connects with hard upper cover plate 1 by self interface arrangment; Described right demist air port 10 connects with hard upper cover plate 1 by self interface arrangment.
The utility model is compared with the split type upper cover plate assembly of existing Automobile instrument owing to adopt all-in-one-piece upper cover plate, cancels the labyrinth and the connection in split type the brim of a hat zone, makes parts connect failure risk and reduces, and structural strength significantly strengthens simultaneously; Because adopting single part to be aided with U type reinforced rib group, the upper cover plate brim structure constitutes, so energy-absorbing effect is better, head bumps performance and significantly improves; Because integral type hard upper cover plate assembly is on manufacturing process, save the raw material of epidermis manufacturing and foaming than similar soft upper cover plate assembly, reduce number of components and draw bail than bulk-breaking formula hard assembly scheme, obvious saving is all being arranged aspect mould, cubing and the assembly process, and comprehensive manufacturing cost significantly reduces.
Above-described, be preferred embodiment of the present utility model only, be not in order to limiting scope of the present utility model, the foregoing description of the present utility model can also be made various variations.Be that every simple, equivalence of doing according to the claims and the description of the utility model application changes and modification, all fall into the claim protection domain of the utility model patent.
