Abstract

The utility model relates to a novel glass guide channel for an automobile, which comprises a door-shaped main body, wherein the inner side of the main body is provided with a first lip and a second lip which relatively stretch, an opening which is embedded with door and window glass is formed between the first and the second lips, and the front and the rear outer side surfaces of the main body are respectively provided with a forth lip and a fifth lip which are used to hook with guide rails. The novel glass guide channel for the automobile is characterized in that the surfaces of the first and the second lips which contact with the door and window glass are adhered with a layer of wear-resisting material smooth layer. Because the novel glass guide channel replaces original flocking or coating through adhering the smooth layer on the lips which contact with the door and window glass, the smooth layer does not have abnormality after abrasion tests for 2000 times in the normal state and 10000 times after four states of thermal ageing, weather resistant, muddy water and warm water impregnation, therefore, the smooth layer still can be firmly adhered on the main body after the door and window glass lift many times in long time, thereby effectively preventing the door and window glass from generating badness of difficult lifting, abnormal noise and migration and the like, and can guarantee the door and window glass to smoothly lift.

Description

A kind of later-model glass run for automobile

Technical field

The utility model relates to a kind of car accessories, specifically refers in a kind of guide rail that is installed on week in the vehicle window frame and glass run that automobile that can the oscilaltion of lead car wind glass is used.

Background technology

On the existing vehicle various upholstery borders are installed, as automobile glass guide slot is upholstery border between automobile window glass and guide rail, match in week in the global shape of glass run and the vehicle window frame, as shown in Figure 1, its main body 1 is " door " font, this glass run is embedded and is being arranged in the vehicle window frame guide rail in week, the inboard of glass run has the first lip limit of relative stretching, extension, the second lip limit, first, form opening between the second lip limit, this opening inserts for the door glass edge, door glass is under the guiding of this glass run, and up-and-down movement in opening makes glass for vehicle window can successfully realize oscilaltion.

Because door glass is in lifting process, and between the first lip limit of glass run and the second lip limit friction is arranged all, the decoration grade that in lifting process, produces noise and improve automobile for fear of door glass, usually the surface on contact with the door glass first lip limit and the second lip limit carry out flocking or on gluing.Take such measure, though can play the noise reduction effect to a certain extent, the former is after driving is one section the time, and fine hair comes off easily, exposes the main body base material and influences outward appearance; Simultaneously with door glass lifting difficulty, the different sound of generation or door glass out-of-position phenomenon; And the high defective of the fraction defective with flocking technique complexity, product.And the following gluing mode of spraying of the latter's online or line, coating often skewness, thickness differs, and is rubbed off by door glass easily and exposes base material, and such structure is understood generator gate window glass up-down difficulty, different sound and or door glass out-of-position phenomenon equally.

The utility model content

Technical problem to be solved in the utility model is at above-mentioned prior art present situation, and a kind of glass run for automobile that smooth lifting of door glass and noiselessness and shift phenomenon are produced is provided.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this later-model glass run for automobile comprises the main body of door type, the first lip limit, the second lip limit that have relative stretching, extension in the inboard of described main body, form the opening that embeds for door glass between this first, second lip limit, have respectively on the forward and backward lateral surface of described main body and be used for the 4th lip limit, the 5th lip limit of colluding mutually with guide rail it is characterized in that: with the smooth layer of contacted described first, second surface, lip limit of door glass with one deck wear-resistant material.

In order to make guide groove better with cooperating of door glass, also have on the inside face of described main body and corresponding the 3rd lip limit of this opening, and on the surface, the 3rd lip limit of the described opening of correspondence, also has the described smooth layer of one deck, like this after assembling, the surface on the 3rd lip limit and the edge of door glass are inconsistent, reduce the side-play amount of door glass in lifting process.

In the door glass lifting process, the edge of door glass also might touch to the forward and backward medial surface of main body, in order to reduce wearing and tearing, also can be on the forward and backward medial surface of described main body with the smooth layer of the described wear-resistant material of one deck, further to guarantee the smooth lifting of door glass.

Satisfying under the wearing and tearing requirement, thick the spending most with 0.1mm～0.2mm of described smooth layer is good, to reduce production costs.

Compared with prior art, because the utility model replaces original flocking or gluing by the smooth layer that adheres to wear-resistant material on the lip limit that contacts with door glass, and this smooth layer is through 10000 times abrasion test after the normality 20000 times, thermal ageing/anti-marquis/muddy water/four kinds of states of warm water immersion and no abnormal, thereby at door glass for a long time repeatedly after the lifting, smooth layer of the present utility model still can be securely attached on the main body, thereby actv. has been avoided bad generations such as door glass lifting difficulty, different sound, skew, can guarantee the smooth lifting of door glass.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1 to Figure 3, this glass run for automobile comprises the main body 1 of door type, the first lip limit 11 that has relative stretching, extension in the inboard of main body, the second lip limit 12, this is first years old, form the opening 16 that embeds for door glass 3 between the second lip limit, have on the inside face of main body and corresponding the 3rd lip limit 13 of this opening, before the main body, have respectively on the back lateral surface and be used for the 4th lip limit 14 of colluding mutually with guide rail, the 5th lip limit 15, simultaneously, with door glass contacted first, surface, the second lip limit is with the smooth layer 2 of one deck wear-resistant material, in the present embodiment, smooth layer adopts the thermoplastic elastomer material.Also has the described smooth layer of one deck on the forward and backward medial surface of main body.In the present embodiment, the thickness of smooth layer 1 is 0.1mm.Certainly the thickness of smooth layer 1 also can be 0.2mm or 0.15mm.

When making above-mentioned glass run, in the extrusion main body, former need flocking or on the described smooth layer of the bonding one deck in position of coating because this smooth layer is the lubricious material of high abrasion, therefore ability overcomes defective of the prior art preferably, makes door glass can successfully carry out lifting.
