Abstract
The utility model discloses a novel assembly structure for a vehicle mirror case. The novel assembly structure is characterized by being formed by assembling a rear cover (1) and the mirror case (2), the rear cover (1) is provided with clamping feet (3) symmetrically, the clamping feet (3) are arranged oppositely in the inner side direction of the rear cover (1), and the root portions of the clamping feet (3) are rounded. A lengthened guide slope (4) is arranged on the lower edge of the rear cover (1) and is in lap joint with the clamping feet (3) in a guide mode. The clamping feet (3) are assembled to the mirror case (2) through the guide slope (4). According to the novel assembly structure, shortcomings are converted into advantages by fully utilizing the characteristic of injection molding deformation, the direction of the clamping feet is set to be consistent with the deformation direction by utilizing inward injection molding deformation of the rear cover, the clamping feet are smoothly clamped into the mirror case through the lengthened guide slope firmly and stably, and interior sheet metal parts can be well protected.
Description
Technical field
The utility model relates to vehicle mirror shell technology field, is specifically related to the novel mounting structure of a kind of vehicle mirror shell.
Background technology
Up to now, the fit structure card base of bonnet is all toward the outer side.The problem points of this kind of fit structure has a lot: 1, very high to injection molding technology requirement, need stable Shooting Technique condition, even so, also be difficult to ensure that Plastic Parts is indeformable, in order to prevent distortion, goods also need to make shape righting tool after taking out, and have increased manpower and material resources cost.
After bonnet is assembled in mirror shell, in driving process, meet the road conditions such as shake, jolt, after time is long, thereby card base will produce creep, wearing and tearing cause bonnet to come off, and sheet metal component is directly exposed in air, the bad problems such as cause getting rusty, intensity declines, and camera lens is loosening.
the content of utility model
For the drawback existing in prior art; the purpose of this utility model is to provide a kind of vehicle mirror shell novel mounting structure; make full use of the feature of injection molding deformation; change defect is advantage, utilizes bonnet injection molding deformation inwards, card base direction is set also consistent with deformation direction; by the guiding surface lengthening; snap in smoothly in mirror shell, firm and stable, can well protect inner sheet metal component.
The technical scheme that the utility model is taked is:
The novel mounting structure of a kind of vehicle mirror shell, it is characterized in that, be assembled by bonnet (1) and mirror shell (2), on described bonnet (1), be symmetrical arranged card base (3), card base (3) is oppositely arranged along the direction of bonnet (1) inner side, the root rounding of card base (3), and the lower edge of described bonnet (1) arranges the guiding surface (4) of lengthening, guiding surface (4) and card base (3) guiding overlap joint, card base (3) is assembled on mirror shell (2) by guiding surface (4).
Further, described card base (3) is arranged on the position, two base angles, left and right of bonnet (1).
Further, described guiding surface (4) middle part is arcs of recesses.
Further, in injection moulding process, the inside shrinkage distortion of the right and left of bonnet (1).
Further, the material of described bonnet (1) is polypropylene.
The beneficial effects of the utility model are:
1, in the utility model, utilize the feature of bonnet injection molding deformation; by the card base consistent with deformation direction and guiding surface, snap in mirror shell, distortion and card base amount of lap provide enough power; make bonnet snapping in mirror shell tightly, thus protection sheet metal component and good outward appearance.
2, the symmetrical card base root rounding on bonnet, in injection moulding process, the inside shrinkage distortion of the right and left of bonnet, avoids Root Stress to concentrate, and ensures that in fitting process, card base can not rupture.
3, the raw MAT'L of bonnet is polypropylene, contractibility is very large, add the restriction of injecting condition, after goods depanning, be difficult to the conformability in guarantee and data, can produce along left and right directions shrinkage distortion inwards, bonnet utilizes injection molding deformation and the card base guiding overlap joint consistent with deformation direction, can be assembled to smoothly on mirror shell, the risk that firmly and not comes off, larger guiding surface, has avoided card base to produce the difficulty of fit on because not leading.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of card base in the utility model.
Wherein, 1, bonnet; 2, mirror shell; 3, card base; 4, guiding surface.
Detailed description of the invention
Further illustrate the utility model below in conjunction with accompanying drawing 1 and accompanying drawing 2.
The novel mounting structure of a kind of vehicle mirror shell, it is characterized in that, be assembled by bonnet 1 and mirror shell 2, on described bonnet 1, be symmetrical arranged card base 3, card base 3 is oppositely arranged along the direction of bonnet 1 inner side, the root rounding of card base 3, and the lower edge of described bonnet 1 arranges the guiding surface 4 of lengthening, guiding surface 4 and card base 3 guiding overlap joints, card base 3 is assembled on mirror shell 2 by guiding surface 4.
Further, described card base 3 is arranged on the position, two base angles, left and right of bonnet 1.
Further, described guiding surface 4 middle parts are arcs of recesses.
Further, in injection moulding process, the inside shrinkage distortion of the right and left of bonnet 1.
Further, the material of described bonnet 1 is polypropylene.
Mounting structure as shown in Figure 1, symmetrical card base 3 root roundings on bonnet 1, and card base direction is consistent with the direction of arrow.In injection moulding process, bonnet 1 is along direction of arrow shrinkage distortion.Card base 3 consistent with deformation direction when assembling is assembled in mirror shell 2 by the guiding surface 4 lengthening, and is combined together securely with mirror shell 2, well protects inner sheet metal structural.
Above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-described embodiment; variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present utility model, also should belong to protection domain of the present utility model.
