Abstract

A hidden belt weatherstrip assembly is provided on a vehicle door sheet metal with a first positioning member. The hidden belt weatherstrip assembly includes an outer belt weatherstrip. A first injection-molded joint corner is provided on an end side of the outer belt weatherstrip. A first positioning portion is provided on the first injection-molded joint corner. The first positioning member is fitted to the first positioning portion. The first injection-molded joint corner is fixed to the vehicle door sheet metal.

Claims (38)

1 . A hidden belt weatherstrip assembly, provided on a vehicle door sheet metal connected with a first positioning member, comprising:

an outer belt weatherstrip,

wherein:

a first injection-molded joint corner is provided on an end side of the outer belt weatherstrip, and a first positioning portion is provided on the first injection-molded joint corner; and

the first positioning portion comprises an open structure being downwardly open and extending from the end side of the outer belt weatherstrip, the open structure having an opening profile with varying widths to limit movement of the first positioning member, wherein:

the first positioning member is inserted from the end side of the outer belt weatherstrip and fitted into the open structure of the first positioning portion along a vertical direction perpendicular to a length direction of a vehicle body;

the first positioning member comprises a positioning column attached to and protruding from the vehicle door sheet metal and a limiting block arranged at an end of the positioning column, the positioning column extending into the open structure of the first positioning portion, and the limiting block being inserted into the open structure and retained by the opening profile having varying widths to constrain the outer belt weatherstrip relative to the vehicle door sheet metal; and

the first injection-molded joint corner is fixed to the vehicle door sheet metal.

2 . The hidden belt weatherstrip assembly according to claim 1 , further comprising:

an inner belt weatherstrip located below the outer belt weatherstrip.

3 . The hidden belt weatherstrip assembly according to claim 2 , wherein a second injection-molded joint corner is provided on an end side of the inner belt weatherstrip, the second injection-molded joint corner is fixed to the vehicle door sheet metal, and the second injection-molded joint corner is provided corresponding to the first injection-molded joint corner.

4 . The hidden belt weatherstrip assembly according to claim 1 , wherein the open structure of the first positioning portion is a slot.

5 . The hidden belt weatherstrip assembly according to claim 4 , wherein the slot has an accommodating area and an opening in communication with the accommodating area, and the limiting block of the first positioning member is clamped into the accommodating area through the opening along the vertical direction.

6 . The hidden belt weatherstrip assembly according to claim 5 , wherein the slot further has guiding edges inclined outwards and downwards from the opening to both sides of the slot.

7 . The hidden belt weatherstrip assembly according to claim 4 , wherein a depth of the slot is less than a thickness of a corresponding position of the outer belt weatherstrip.

8 . The hidden belt weatherstrip assembly according to claim 4 , wherein the first injection-molded joint corner and the first positioning portion are integrally formed by injection molding.

9 . The hidden belt weatherstrip assembly according to claim 1 , wherein the positioning column is configured to protrude towards the outer belt weatherstrip along a sheet metal surface of the vehicle door sheet metal.

10 . The hidden belt weatherstrip assembly according to claim 9 , wherein the limiting block is configured to be clamped into the first positioning portion.

11 . The hidden belt weatherstrip assembly according to claim 9 , wherein the positioning column is in a welded connection with the vehicle door sheet metal.

12 . The hidden belt weatherstrip assembly according to claim 1 , wherein the first positioning member is connected with the first injection-molded joint corner in the length direction of the vehicle body.

13 . The hidden belt weatherstrip assembly according to claim 12 , wherein the first positioning member is connected with the first injection-molded joint corner in the length direction of the vehicle body by a lap amount of 2.0 mm to 3.0 mm.

14 . The hidden belt weatherstrip assembly according to claim 1 , wherein the first positioning member is connected with the first injection-molded joint corner.

15 . The hidden belt weatherstrip assembly according to claim 1 , wherein the open structure of the first positioning portion comprises a notch downwards.

16 . A vehicle door, comprising:

a vehicle door sheet metal connected with a first positioning member; and

a hidden belt weatherstrip assembly, comprising:

an outer belt weatherstrip,

wherein:

a first injection-molded joint corner is provided on an end side of the outer belt weatherstrip, and a first positioning portion is provided on the first injection-molded joint corner; and

the first positioning portion comprises an open structure being downwardly open and extending from the end side of the outer belt weatherstrip, the open structure having an opening profile with varying widths to limit movement of the first positioning member,

wherein:

the first positioning member is inserted from the end side of the outer belt weatherstrip and fitted into the open structure of the first positioning portion along a vertical direction perpendicular to a length direction of a vehicle body;

the first positioning member comprises a positioning column attached to and protruding from the vehicle door sheet metal and a limiting block arranged at an end of the positioning column, the positioning column extending into the open structure of the first positioning portion, and the limiting block being inserted into the open structure and retained by the opening profile having varying widths to constrain the outer belt weatherstrip relative to the vehicle door sheet metal; and

the first injection-molded joint corner is fixed to the vehicle door sheet metal.

17 . The vehicle door according to claim 16 , wherein the hidden belt weatherstrip assembly further comprises an inner belt weatherstrip located below the outer belt weatherstrip.

18 . The vehicle door according to claim 16 , wherein the open structure of the first positioning portion is a slot.

19 . The vehicle door according to claim 16 , wherein the positioning column is configured to protrude towards the outer belt weatherstrip along a sheet metal surface of the vehicle door sheet metal.

20 . The vehicle door according to claim 16 , wherein the first positioning member is connected with the first injection-molded joint corner in the length direction of the vehicle body.
