The utility model will be described in detail below with reference to the drawings in connection with embodiments.

The embodiment relates to a vehicle door sealing strip, which comprises a sealing strip body and a joint angle 2 connected with the sealing strip body. The inside cavity 101 that is formed with of sealing strip body connects angle 2 and sealing strip body connection's one end is equipped with drawing of patterns groove 201, and drawing of patterns groove 201 and cavity 101 intercommunication.

In the door weather strip of the present embodiment, the demolding groove 201 is provided in the joint angle 2, and the demolding groove 201 communicates with the cavity 101 of the weather strip body. After the joint angle 2 is poured, the inner film in the sealing strip body can be smoothly pulled out through the demolding groove 201, so that the demolding of the sealing strip is facilitated, and the problem that the appearance and sealing are affected due to the fact that the joint angle 2 is easy to collapse due to the fact that an opening is formed at the joint angle 2 in the prior art is avoided.

Based on the above overall description, an exemplary structure of the door weather strip of the present embodiment is shown in fig. 1, and the joint angle 2 of the present embodiment is made of an integrally formed rubber or TPV material. The first sealing strip 4 is connected to this angle of connecing 2 one end, and the angle of connecing 2 other end is connected with second sealing strip 1, and wherein second sealing strip 1 includes foretell sealing strip body.

The door sealing strip of this embodiment can be used to be located the frame angle 2 department of B post and C post, also can be used to the frame angle 2 department of connecting between A post and the B post, and first sealing strip 4 and second sealing strip 1 can be door upper seal strip or door side sealing strip. The joint angle 2 of the embodiment can be used for connecting two sealing strips and also can be used for connecting three sealing strips.

As a specific embodiment, the joint angle 2 of the present embodiment is integrally cast with each sealing strip to which it is connected. Because the second sealing strip 1 is provided with the cavity 101, after pouring of the joint angle 2 and the second sealing strip 1 is completed, the inner film of the second sealing strip 1 is blocked in the cavity 101 of the sealing strip body.

As shown in fig. 1 and 2, in the present embodiment, the demolding groove 201 is provided at a side of the joint angle 2 near the weatherstrip body. The demolding groove 201 is a rectangular groove formed on the joint angle 2 and opened towards one side of the vehicle door, a through hole 205 communicated with the cavity 101 is formed in the side surface of the groove, close to the sealing strip body, of the groove, and the appearance of the through hole 205 is consistent with that of the cavity 101.

By the arrangement, after pouring is completed, the inner film of the second sealing strip 1 can be extracted from the demolding groove 201, so that the problem that the joint angle 2 collapses due to the fact that an opening communicated with the cavity 101 of each sealing strip is required to be formed in the joint angle 2 in the prior art is avoided.

In addition, in order to achieve a better demolding effect, as shown in fig. 3 to 5, the depth of the demolding groove 201 in the embodiment is greater than or equal to the depth of the butt angle 2 of the cavity 101. The width of the ejector slot 201 is greater than the maximum width of the profile of the cavity 101. The depth of the demolding groove 201 can be gradually reduced from the second sealing strip 1 to one end of the joint angle 2, so that the inner film is guided to the outlet of the demolding groove 201 to facilitate the demolding of the inner film when the inner film is pulled out.

As a preferred embodiment, the connecting angle 2 of the present embodiment is embedded with a skeleton 3, and the skeleton 3 is provided with a buckle 301 extending out of the connecting angle 2, where the buckle 301 is used for connecting with a door sheet metal. As shown in fig. 1, 2, 6 and 7, the skeleton 3 of the present embodiment is provided with the following angle 2, and two fasteners 301 protruding toward the vehicle body frame direction are formed at the bending position of the skeleton 3, and the fasteners 301 have the same structure as the prior art.

The provision of the framework 3 makes it possible to provide the door seal with structural strength at the door joint angle 2.

In addition, in order to prevent the relative displacement between the frame 3 and the joint angle 2, a limit groove 302 corresponding to the buckle 301 is provided on the frame 3, the limit groove 302 is provided at one end of the frame 3 in the width direction, and the joint angle 2 is recessed to form a limit protrusion 202 embedded in the limit groove 302.

As shown in fig. 7 and 8, the limiting groove 302 is gradually recessed from one side of the frame 3 to the other side along the thickness direction of the frame 3, and the bottom surface of the limiting groove 302 forms a downward inclined surface on the frame 3. As shown in fig. 8, a limiting protrusion 202 attached to the inclined surface is formed at a position corresponding to the limiting groove 302 on the joint angle 2. In order to achieve light weight, the limiting protrusion 202 is provided with a lightening hole with an opening at one end.

In order to achieve a better limiting effect, the number of the limiting protrusions 202 and the number of the limiting protrusions 301 are multiple, and the limiting protrusions 202 and the limiting protrusions 301 are arranged in a one-to-one correspondence manner. In a specific structure, as shown in fig. 7 and 8, three limiting grooves 302 are disposed at the bending position of the skeleton 3, that is, at the positions of the two buckles 301, and at the center between the two buckles 301.
