Abstract
The utility model discloses a sealing strip for an automobile. The sealing strip comprises a base body and a foaming piece connected with the base body. A clamping hole is formed in the base body. At least two protrusions are arranged on the top face of the foaming piece, the foaming piece is provided with a cavity, and a first thickness area and a second thickness area thinner than the firs thickness area are arranged on the side wall of the cavity. The second thin thickness area is formed on the side wall of the foaming piece to form a yielding mechanism, and when the foaming piece and a metal plate are in contact and are compressed, the foaming piece can be bent along the second thickness area, and the foaming piece is prevented from deformation compression and damage. Systemic resistance in the compression process can be reduced, good sealing performance is facilitated, and the service life of the sealing strip is prolonged.
Description
Technical field
The utility model relates to vehicular spare parts field, specifically relates to a kind of weather strip for automobile.
Background technology
At present, in order to meet better the pursuit of customer to automobile function quality, each auto vendor constantly improves the various aspects of performance of car load, the sealing band of car just can well embody this point, the front deck sealing band of general sealing band automobile and the joint form of front cover are all fairly simple, have leak tightness shortcoming, cracky phenomenon.
Utility model content
In order to solve existing sealing band, have leak tightness shortcoming, cracky phenomenon, the utility model provides a kind of weather strip for automobile.
The technical scheme that the utility model embodiment adopts is: a kind of weather strip for automobile, comprising: matrix is provided with blocked hole with the foaming piece being connected with matrix phase, described matrix; The end face of described foaming piece is provided with at least two projections, and described foaming piece has a cavity, and the sidewall of described cavity has the second thickness area of the first thickness area and ratio the first thin thickness.
Preferably, described projection is arranged on the both sides of foaming piece end face.
Preferably, described projection has wedge angle.
Preferably, in described matrix, be provided with skeleton.
Preferably, in described blocked hole, be provided with the flexible catch that multilayer disconnects.
Preferably, described catch is provided with barb at gap.
The beneficial effects of the utility model are: the utility model by being formed with the second thinner thickness area on foaming piece sidewall, form surrender mechanism, when contacting compression with panel beating, foaming piece can, along the bending of the second thickness area place, prevent distortion compression and the breakage of foaming piece.And be also conducive to reduce the systemic resistance in compression process, be more conducive to good leak tightness, extend the sealing band life-span.
Accompanying drawing explanation
Fig. 1 is existing gasket structure schematic diagram;
Fig. 2 is the section drawing of the sealing band of a kind of embodiment of the utility model.
The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in 2, be the structural representation of a kind of embodiment of the utility model, this weather strip for automobile comprises matrix 200 and the foaming piece 100 being connected with matrix phase, described matrix 200 is provided with blocked hole 201; The end face of described foaming piece 100 is provided with at least two projections 101, and described foaming piece has a cavity, and the sidewall of described cavity has the second thickness area 102 of the first thickness area and ratio the first thin thickness.Fig. 2 shows the section drawing of the utility model sealing band, and sealing band of the present utility model is strip, and foaming piece has cavity.
On the sidewall of the utility model sealing band, be formed with the second thinner thickness area, form surrender mechanism, when contacting compression with panel beating, foaming piece can be along the bending of the second thickness area place, prevent distortion compression and the breakage of foaming piece, and be also conducive to reduce the systemic resistance in compression process, be more conducive to good leak tightness, extend the sealing band life-span.
The utility model projection 101 is arranged on the both sides of foaming piece end face, at the end face of foaming piece, forms two fulcrums, when contact with panel beating, can increase the area of contact with panel beating, and formation face contacts.The utility model projection can be various applicable shapes, and for example circular, square etc., preferably, this projection has wedge angle.
Can be one-body molded between foaming piece of the present utility model and matrix, be closely connected with matrix, can also be bonding, hinged etc.
The second thickness area 102 of the present utility model can be any region at foaming piece sidewall, and for example 1/3 or 2/3 region, preferably, in the region, middle and upper part of foaming piece sidewall, does not contact with matrix phase while making foaming piece bending.The present embodiment is respectively provided with the second thickness area of an attenuate on the first side wall and the second sidewall, can be symmetrical or asymmetric setting, makes this foaming piece when being under pressure, and first from weakened region bending, prevents distortion compression and the breakage of foaming piece.This second thickness can be than the first thin thickness 20%-50%.For example the first thickness is 20mm, and the second thickness is 10mm.
In blocked hole of the present utility model, every one deck catch comprises left catch and right catch, is connected respectively with base side walls.Preferably, catch is provided with barb at gap, further prevents that metal piece from departing from.Left catch one end is connected with base side walls, near the second end of right catch, has barb, thereby can strengthen and being connected of metal piece.Right catch also has same structure.
Embodiment in Fig. 2 is provided with the flexible catch of two-layer disconnection in blocked hole, can coordinate with metal piece, and be contacted and be connected with metal piece by flexible catch, thereby increase the combination with metal piece.Preferably, in matrix 200, be provided with metallic framework 202, increased the rigidity of matrix.
The beneficial effect of technique scheme is: the utility model by being formed with the second thinner thickness area on foaming piece sidewall, form surrender mechanism, when contacting compression with panel beating, foaming piece can, along the bending of the second thickness area place, prevent distortion compression and the breakage of foaming piece.And be also conducive to reduce the systemic resistance in compression process, be more conducive to good leak tightness, extend the sealing band life-span.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
