Description

Sealing strip for automobile trunk

Technical Field

The application relates to the technical field of automobile parts, in particular to a sealing strip for an automobile trunk.

Background

The automobile sealing strip is one of important parts of an automobile, is usually used for parts such as doors, windows, bodies, skylights, engine cases, trunks and the like, and plays roles of water resistance, dust resistance and smoke resistance. In practice, it is found that due to the rear cover sheet metal structure and the car body arrangement, when a car is washed under high pressure, high-pressure water flow directly impacts the foam pores of the sealing strip, so that the sealing strip is deformed under the action of the water pressure, and cannot play a waterproof role, so that the water flow enters a trunk, and a user complains about the water flow. In the prior art, a mode of changing a rear cover sheet metal structure and vehicle body arrangement or adding a water retaining part is adopted, so that high-pressure water flow is prevented from directly impacting a sealing strip, and a waterproof effect is achieved. However, through the scheme of changing the rear cover sheet metal structure and the vehicle body arrangement, the influence on peripheral parts is large, the improvement period is long, and the influence on the scheduled delivery of the automobile is large; the scheme of adding the water retaining part can greatly increase the material cost and is not easy to arrange.

SUMMERY OF THE UTILITY MODEL

In order to solve at least one aspect of the above problems, the present invention provides a sealing strip for a trunk of an automobile, comprising a top strip, two side strips and a bottom strip, wherein the top ends of the two side strips are respectively fixedly connected with two ends of the top strip, and the bottom ends of the two side strips are respectively fixedly connected with two ends of the bottom strip; the top strip comprises a first bubble hole, a first mounting clamping seat and a water retaining strip; the extension size of the first foam hole, the extension size of the first mounting clamping seat and the extension size of the water retaining strip are matched with the extension size of the top of the opening of the trunk, and the bottom end of the first foam hole is fixedly connected with the top end of the first mounting clamping seat; the water bar is made of hard rubber, the first side face of the water bar is fixedly connected with the side face of the first mounting clamping seat, the width of the water bar enables the sealing strip to be mounted on the trunk, and when the automobile rear cover is closed, the bottom face of the automobile rear cover is abutted to the position, close to the second side face, of the water bar.

Through the technical scheme, add the breakwater in the top strip, avoided high-pressure rivers direct impact first bubble, when the high-pressure carwash, the breakwater can be strikeed to high-pressure rivers, then discharge after flowing to the tye of automobile body along the outside of first installation cassette, thereby waterproof effect has been played, and adopt stereoplasm rubber to make the breakwater, make the shock resistance ability of breakwater strong, consequently, the sealing strip simple structure of this application, simple to operate, waterproof performance is good, development cycle is short, the not enough of current waterproof scheme has been solved.

Preferably, a reinforcing strip is fixedly arranged on the second side surface of the water retaining strip; the extending size and the extending direction of the reinforcing strip are the same as those of the water bar, and the shape of the top surface of the joint of the reinforcing strip and the water bar is matched with the shape of the joint of the automobile rear cover and the water bar. Through above-mentioned technical scheme, help improving the intensity of water bar second side to improve the stability that back lid and water bar are connected.

Preferably, the inside of reinforcing bar has seted up the through-hole along the extending direction of reinforcing bar.

Preferably, sidebar and bottom strip all include second bubble and second installation cassette, the size of extension of the second bubble in the sidebar and the size of extension of second installation cassette all with the size phase-match that extends of the lateral part of suitcase opening part, the size of extension of the second bubble in the bottom strip and the size of extension of second installation cassette all with the size phase-match that extends of the bottom of suitcase opening part, the bottom of second bubble and the top fixed connection of second installation cassette. Because the bottom strip and the side strip are covered by the rear cover, the high-pressure water flow cannot impact the bottom strip and the side strip, the hidden danger of water inflow in the high-pressure car washing process does not exist in the bottom strip and the side strip, and the water retaining strip is not added in the bottom strip and the side strip through the technical scheme, so that the weight is favorably reduced.

Preferably, the top strip, the two side strips and the bottom strip are integrally formed.

Preferably, the first mounting clamp seat and the second mounting clamp seat are both fixedly provided with a framework.

Preferably, the first mounting clamping seat is fixedly connected with a mantle away from the side face of the water retaining strip, and the second mounting clamping seat is fixedly connected with a mantle on the side face.

Preferably, the bottom ends of the first and second mounting brackets are fixedly connected with decorative edges.
