Description

A kind of automobile door frame sealing strip

technical field

The utility model relates to the field of sealing systems of automobile parts, in particular to an automobile door frame sealing strip.

Background technique

The car door frame seal is a kind of car sealing parts, which is installed on the edge of the car door frame to seal the gap between the car door and the car door frame. The cross-sectional structure of the automobile door frame weather strip is shown in Figure 1, mainly including the clamping part 1 and the sealing part 2; wherein the clamping part 1 is used to fix the automobile door frame weather strip on the door frame of the automobile door; the sealing part 2 is located on the mounting part One side of the locking part 1 is connected with it, and is used for sealing the gap between the door and the door frame after the door is closed tightly. In order to prevent the automobile door frame sealing strip from disengaging or falling off during work, a metal skeleton 3 (or called a steel core) is usually embedded in the clamping part 1 to increase its strength.

And the automobile door frame sealing strip is not only a kind of sealing member of the car door, but also an interior part of the car, and the outer surface 6 of the clamping part 1 near the inner side of the car affects the decorative effect in the car. At present, colored fluff is usually planted on the outer surface 6 of the clamping part 1 of the automobile door frame weatherstrip close to the inner side of the car as an outer decoration layer to reflect its decorative function. Such as Chinese patent document CN2691916Y discloses a kind of automobile door frame sealing strip, and its foamed sponge sealing strip is connected with the clamping part that is shaped as "U" as a whole, and there are 3 teeth on the edge inside the clamping part, and the clamping part A metal skeleton in the shape of a "U" is fixed in the middle, and the end face of the edge is connected with a section of sponge rubber lip. However, the flocking process of producing this kind of automobile door frame seal has the following disadvantages: ①The process steps are very cumbersome and complicated, and usually need to go through multiple processes such as surface polishing, glue spraying, flocking, curing, and removal of floating fleece, so that the production efficiency Not high; ②Because there are many process steps, the required production line is relatively long and the production area is relatively large; ③Because there are many process steps, the required production machines are relatively large, the energy consumption is large, and the production cost is high; ④The process steps Many, any process will have a direct impact on the quality of flocking, making the quality of flocking unstable, and often lead to waste products due to flocking; ⑤ Moreover, the glue spraying step in the overall process will also cause environmental pollution, which is not conducive to environmental protection .

Utility model content

For this reason, the technical problem to be solved by the utility model is to overcome the cumbersome and complicated flocking process of producing automobile door frame sealing strips in the prior art, which causes low production efficiency, large energy consumption, high cost, large production area and serious pollution. , and high scrap rate, etc., and provide an automobile door frame sealing strip with short production line, high production efficiency, low energy consumption, small production area, clean and pollution-free, and low scrap rate.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is as follows:

An automobile door frame sealing strip, comprising a clamping part and a sealing part connected to the clamping part, the outer surface of the clamping part close to the interior of the car has an outer decorative layer, and the outer decorative layer is bonded to the outer surface superior.

In the above automobile door frame sealing strip, the clamping portion has sealing teeth.

In the above-mentioned sealing strip for the automobile door frame, a metal frame is embedded in the inside of the clamping part.

Compared with the prior art, the above-mentioned technical solution of the utility model has the following advantages: 1. The outer decoration layer of the automobile door frame sealing strip of the utility model is a thermoplastic elastomer layer. When producing this automobile door frame sealing strip, only It is only necessary to cover the thermoplastic elastomer layer on the side of the clamping part close to the inside of the car, without using the flocking process, which completely solves various defects caused by the flocking process; ② due to the production of the utility model provided This kind of automobile door frame sealing strip has few process steps, so the production line is relatively short, the production efficiency is high, the energy consumption is small, the cost is low, the production area is small, the scrap rate is low, and there is no glue spraying step, clean and pollution-free.

Description of drawings

In order to make the content of the utility model easier to understand clearly, the utility model will be described in further detail below according to specific embodiments of the utility model in conjunction with the accompanying drawings, wherein

Fig. 1 is the sectional schematic diagram of existing automobile door frame sealing strip;

Fig. 2 is a schematic cross-sectional view of the automobile door frame sealing strip of the present invention.

The reference numerals in the figure are represented as: 1 - clamping part, 2 - sealing part, 3 - metal skeleton, 4 - exterior decoration layer, 5 - sealing teeth, 6 - outer surface.

Detailed ways

As shown in Figure 2, it is a preferred embodiment of the automobile door frame sealing strip of the present invention, and the automobile door frame sealing strip includes a clamping part 1, a sealing part 2, and a metal skeleton embedded in the clamping part 1 3.

The clamping part 1 is EPDM (EPDM, Ethylene-Propylene-DieneMonomer); the clamping part 1 has sealing teeth 5; Covered with an exterior decoration layer 4, the exterior decoration layer 4 is bonded on the outer surface 6 of the clamping portion 1 close to the interior of the car; the exterior decoration layer 4 is a thermoplastic elastomer layer (the thermoplastic elastomer layer That is TPE, thermoplastic elastomer), in this embodiment, the thermoplastic elastomer layer is specifically a thermoplastic vulcanizate layer (the thermoplastic vulcanizate is TPV, Thermoplastic Vulcanizate). The sealing part 2 is located on one side of the clamping part 1 and is connected with the clamping part 1, and the sealing part 2 is made of sponge rubber.

The automobile door frame sealing strip provided by the utility model does not need to adopt flocking process during production, and completely solves various defects caused by the flocking process. The production of the automobile door frame sealing strip provided by the utility model requires few process steps, so the production line is relatively short, the production efficiency is high, the energy consumption is small, the cost is low, the production area is small, the reject rate is low, and there is no need for spraying Glue step, clean and pollution-free.

Apparently, the above-mentioned embodiments are only examples for clear description, rather than limiting the implementation. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here.
