Description

Prevent closing door and pat sound guide groove sealing strip

Technical Field

The utility model belongs to the field of automobiles, and particularly relates to a door-closing prevention flapping sound guide groove sealing strip.

Background

The novel frameless car door is used for meeting the requirements of a car factory on the appearance of the whole car, and the upper half part of the car door is not provided with a sheet metal support; the glass guide groove sealing strip can ensure that the glass of the vehicle door is sufficiently supported, and when the glass rises to 2/3, the glass can shake due to insufficient strength of the self-carried fixing structure; and the material of glass run channel sealing strip is harder, very easy and the glass that rocks produce each other many frequency striking, especially when the door is closed, receive the impact force influence of closing the door, produce vibrations friction with the glass sealing strip, still can cause abnormal sound.

Disclosure of Invention

The utility model aims at: in order to solve the problems of shaking and abnormal sound of the frameless door glass, the sealing strip for preventing the door from being closed and flapping with the sound guide groove is provided.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the sealing strip comprises a sealing strip fixed in a vehicle door, wherein the sealing strip is arranged along the boundary of the vehicle door glass in a closed state and according to the requirements of a frameless vehicle door; the section of the sealing strip is V-shaped, and a fixing strip facing the outside of the opening is fixed on one side of the opening end of the sealing strip; the sealing strip opening end both sides all are fixed with a buffer strip towards the opening inboard, are arranged in on the opening outside terminal surface on the buffer strip and are fixed with one deck high elasticity EPDM foaming sponge material layer, are filled by the closely knit material layer of EPDM between sealing strip and the buffer strip.

As a further description of the above technical solution:

the sealing strip is made of EPDM dense material.

As a further description of the above technical solution:

a plurality of lips are fixed on the outer edge surface of the fixing strip, and the lips are made of compact rubber materials.

As a further description of the above technical solution:

the buffer strip is formed by compounding and extruding a high-elasticity EPDM foaming sponge material arranged at the outer end of the opening and an EPDM compact material arranged at the inner end of the opening.

As a further description of the above technical solution:

the outer side end face of the buffer strip is made of glass, and the buffer strip is overlapped with the reciprocating movement direction of the glass in a crossing manner.

In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:

(1) When the glass rises, the high-elasticity EPDM foamed sponge material layer on the buffer strip contacts and forms extrusion, so that the buffer strip is deformed, the buffer strip and the high-elasticity EPDM foamed sponge material layer on the buffer strip always provide supporting force, and the shaking phenomenon of the glass is avoided when the glass rises;

(2) The utility model realizes that the buffer strip and the EPDM compact material layer filled in the buffer strip always provide supporting force when the vehicle door is opened and closed, so as to reduce the impact force of the vehicle door glass on the sealing strip, effectively buffer the impact force and solve the beating sound when the vehicle door is opened and closed.

(3) The utility model is suitable for door without door frame, ensures that no vibration abnormal sound is generated when the door is opened and closed, meets the requirements of automobile factories on the appearance of the whole automobile, reduces the windage coefficient of the whole automobile, and improves the automobile feeling of customers.

fig. 2 is a schematic view of the position of the glass 7 when the present utility model is used, wherein a is the moving direction of the glass 7, and B is the vibrating direction of the glass 7.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, the present utility model provides a technical solution for preventing a door from being closed and flapping to a sealing strip 1 of a sound guiding groove:

the door-closing-prevention flapping sound guide groove sealing strip 1 comprises a sealing strip 1 fixed in a vehicle door, wherein the sealing strip 1 is arranged along the boundary of the vehicle door glass 7 in a closed state and according to the requirements of a frameless vehicle door; the section of the sealing strip 1 is V-shaped, and a fixing strip 2 facing the outside of the opening is fixed on one side of the opening end of the sealing strip 1; the two sides of the opening end of the sealing strip 1 are both fixed with a buffer strip 3 facing the inner side of the opening, a layer of high-elasticity EPDM foaming sponge material layer 4 is fixed on the end face of the outer side of the opening on the buffer strip 3, and the sealing strip 1 and the buffer strip 3 are filled with an EPDM compact material layer 5.

The sealing strip 1 is made of EPDM dense material.

A plurality of lips 6 are fixed on the outer edge surface of the fixing strip 2, and the lips 6 are made of compact rubber materials.

The buffer strip 3 is formed by compounding and extruding a high-elasticity EPDM foaming sponge material arranged at the outer end of the opening and an EPDM compact material arranged at the inner end of the opening.

The outer end face of the buffer strip 3 is glass 7, and the buffer strip 3 and the glass 7 are overlapped in a cross mode in the reciprocating movement direction.

Working principle:

arranging the sealing strip 1 along the boundary of the closed state of the door glass 7 according to the requirements of the frameless door, and forming clamping connection with a vehicle body trim 8 through a plurality of lips 6 on the fixing strip 2 to fix the sealing strip 1; after the sealing strip 1 is fixed, the outer end face of the buffer strip 3 is overlapped with the reciprocating movement direction of the glass 7 in a crossing way. When the glass 7 moves along the length direction, the glass can be contacted with the high-elasticity EPDM foaming sponge material layer 4 on the buffer strip 3 to form extrusion, so that the buffer strip 3 is deformed, the buffer strip 3 and the high-elasticity EPDM foaming sponge material layer 4 on the buffer strip always provide supporting force, and the shaking phenomenon of the glass 7 is avoided when the glass rises; when the door is opened and closed to enable the glass 7 to move along the thickness direction of the door, the buffer strip 3 and the EPDM compact material layer 5 filled in the buffer strip always provide supporting force so as to reduce the impact force of the door glass 7 on the sealing strip 1, effectively buffer the impact force and solve the flapping sound when the door is opened and closed.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and those skilled in the art should appreciate that the technical scheme and the inventive concept according to the present utility model are equivalent or changed within the scope of the present utility model.
