The specific embodiment
In order to make those skilled in the art better understand technical scheme of the present invention, below in conjunction with accompanying drawing, the present invention is described in detail.
Shown in Fig. 3-8, in a kind of specific embodiment, the invention provides a kind of clamping mechanism of handrail blanking cover, this clamping mechanism comprises blanking cover 3 and is located at the projection 31 of blanking cover 3, bolt hole 41 interference fit of projection 31 and handrail 4.In order to overcome this defect of bolt hole that in prior art, stopple is easily deviate from handrail, the present invention has made following technological improvement to this: on blanking cover 3, set up block tongue 32, at the interior draw-in groove 42 that arranges of bolt hole 41, block tongue 32 coordinates clamping with draw-in groove 42.This technical scheme is on the basis of blanking cover 3 and handrail 4 interference fit, increase the clamping location structure between blanking cover 3 and handrail 4, avoided coming off of blanking cover 3, solved in prior art and without any location structure, held caducous problem between stopple and the bolt hole of handrail.
In the above-mentioned specific embodiment, preferably, at the spigot surface that end arranges wedge shape that snaps in of block tongue 32, this spigot surface is convenient to snapping in of block tongue 32, meanwhile, preferably block tongue 32 is plane with the card access surface of draw-in groove 42, and this scheme is made as inclined-plane by card access surface and compares, clamping is more firm, and effect is more excellent.
Block tongue 32 can be located at the outer wall of projection 31, in projection 31 and bolt hole 41 interference fit, realize the clamping of block tongue 32 and draw-in groove 42, yet, consider that block tongue 32 clamping deflections are when larger, interface arrangment is more stable, and block tongue 32 is located at protruding 31 o'clock, during block tongue 32 distortion, can be subject to the restriction of projection 31, clamping deflection is relatively little, causes clamping unreliable.In view of above defect, in the present embodiment, preferably block tongue 32 is set to separately to cantilevered interface arrangment.This scheme can increase the elasticity of block tongue 32, thereby increases the clamping deflection of block tongue 32, makes clamping more reliable.And more preferably, the weakening of Joint strenght while arranging separately in order to make up block tongue 32, increases block tongue 32 and the area of the junction of blanking cover 3, thereby increases both Joint strenghts, avoids the stress of both junctions concentrate and cause block tongue to rupture.
Projection 31 is interference fit with bolt hole 41, can guarantee that blanking cover 3 is connected with the tight of handrail 4.Projection 31 can be selected following embodiment.Embodiment mono-: projection 31 is made as entity structure, by it, realized and coordinates location with the magnitude of interference of bolt hole 41, and in this embodiment, self intensity and larger with the Joint strenght of blanking cover 3 of protruding 31, can not be out of shape or rupture.Yet the deflection of projection 31 is relative also less, when designing both magnitudes of interference, consider this factor, it is relatively little that the magnitude of interference protruding and bolt hole can design, and after so arranging, after projection 31 coordinates with bolt hole 41 is long-term, meeting produces permanent plastic deformation and causes loosening or relative collecting together.
Embodiment bis-: projection 31 is made as a plurality of, and a plurality of projections arrange along the circumferential interval of bolt hole, and this scheme increases to some extent compared with scheme one resilience in comparison, but assembly process process is poor and difficulty of processing is higher.Based on foregoing description, the preferred embodiment of the present invention three: projection 31 is set to curved slab, and curved slab is located at a side of block tongue 32 and along the opposite side that circumferentially extends to block tongue 32 of bolt hole 41, projection 31 respectively with interval, the both sides predeterminable range of block tongue 32.Embodiment tri-compares the deflection that has increased projection 31 compared with embodiment mono-, compared with embodiment bis-, relatively improved its difficulty of processing and assembly process process, and because of the structure of curved slab for extending to form continuously, Joint strenght also can meet operating needs.
And further, projection 31 is from shrinking gradually tapered structure with the junction of blanking cover 3 along the degree of depth of bolt hole 41, and meanwhile, bolt hole 41 is also made as taper hole, by the large end of projection 31 and the large end of taper hole, realizes interference fit.This structure has reduced the coordinate area of projection 31 with bolt hole 41, and whole outer walls of more protruding 31 coordinate and compare with the inwall of bolt hole 41, has reduced the working accuracy of projection 31 with bolt hole 41, has improved both fit qualities.During installation, the small end of projection 31 is put into bolt hole 41, small end also can play directional tagging when assembling, when reaching the matching part of projection 31 and bolt hole 41, presses blanking cover 3, the interference that can realize both connects, this scheme coordinates area relatively little, assemble simple and convenient, simultaneously by the optimization with bolt hole 41 both matching parts to projection 31, the fitting surface having improved between blanking cover 3 and handrail 4 is poor, makes both cooperation outward appearances more attractive in appearance.
In above-mentioned description, bolt hole 41 is made as taper hole, the angle consideration that this structure is manufactured from mould, and the withdrawing pattern at bolt hole place is more prone to.In like manner, also easy withdrawing pattern of the projection of pyramidal structure.Be appreciated that when preferred embodiment three adopts the curved slab of pyramidal structure in the present invention, pyramidal structure can increase the Joint strenght between projection and blanking cover.
As shown in Figure 7, clamping mechanism provided by the invention also comprises registration mast 33, and registration mast 33 coordinates location with the positioning groove 43 of handrail 4.Registration mast 33 can further prevent that blanking cover 3 from collecting together in bolt hole 41, makes both cooperations more stable.Registration mast 33 is preferably rectangular configuration, and positioning groove 43 is rectangular channel, and is preferably opened in the inwall of bolt hole 41, and this structure processing technology is simple.Certainly, registration mast 33 also can be selected other structures such as cylindrical, dovetail form.
Further, registration mast 33 is at least made as two, and a plurality of registration masts 33 arrange along the circumferential interval of bolt hole, and a plurality of registration masts 33 can be strengthened the location that coordinates of blanking cover 3 and handrail 4 better.
The clamping mechanism of handrail blanking cover provided by the invention, blanking cover 3 is assemblied in after handrail 4, and the curved profile of blanking cover 3 and handrail 4 profiles match, and coordinate aesthetics higher.And blanking cover 3, projection 31, block tongue 32 and the preferred integral structure of registration mast 33, adopt Shooting Technique one-body molded, and processing technology is simple.
Automobile provided by the invention comprises the clamping mechanism of handrail blanking cover, and this detent mechanism is the detent mechanism described in above-mentioned arbitrary scheme, because this detent mechanism has above-mentioned technique effect, comprises that the automobile of this detent mechanism should have identical technique effect.
Although the present invention is described in conjunction with above embodiment, but the present invention is not limited to above embodiment, and being just subject to the restriction of claim, this area common technique personnel can easily modify to it and change, but do not leave essence design of the present invention and scope.
