Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an installation structure of a sealing strip joint corner of a vehicle door and a window frame. Background Art

[0002] The door and window frames of a car include an outer window frame panel, an inner window frame panel, decorative bright strips, a decorative cover plate, a sealing strip and a sealing strip corner, etc. The sealing strip corner is clamped to the inner window frame panel through an installation buckle, and is thus installed at the sharp corner of the door and window frame. Its two ends are respectively connected to the sealing strip on the inner side of the door and window frame, and together with the sealing strip, it plays a sealing role. At the same time, the sealing strip corner also plays a role in covering the unsightly parts of the decorative bright strips, decorative cover plates and window frames.

[0003] During long-term use, most existing sealing strip corners are prone to detachment at the joints between the two ends and the door window frame sealing strips due to frequent deformation, which affects the normal use of the sealing strip corners and also reduces the sealing performance of the door when it is closed. Utility Model Content

[0004] The utility model aims to provide a mounting structure for a sealing strip joint corner of a vehicle door and a window frame, so as to solve the technical problems mentioned in the above background technology.

[0005] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0006] A mounting structure for a sealing strip corner of a vehicle door and a window frame, comprising a vehicle door body;

[0007] A sealing strip corner body is arranged on one side of the door body, a safety groove is opened on one side of the door body, and the safety groove is located on one side of the sealing strip corner body, a plurality of groups of support springs are arranged inside the safety groove, a fixing plate is arranged at one end of the support spring, a plurality of groups of compensation springs are arranged on one side of the fixing plate close to the sealing strip corner body, and a constraint plate which fits with the sealing strip corner body is arranged at one end of the compensation spring close to the sealing strip corner body.

[0008] As a further solution of the utility model: the vehicle door body is provided with a first window frame sealing strip on one side of the sealing strip corner body, and one end of the first window frame sealing strip is bonded and fixed to one end of the sealing strip corner body.

[0009] As a further solution of the utility model: a second window frame sealing strip is arranged on one side of the door body provided with the first window frame sealing strip, and one end of the second window frame sealing strip is bonded and fixed to the other end of the sealing strip corner body.

[0010] As a further solution of the utility model: the first window frame sealing strip and the second window frame sealing strip are both provided with a slot at one end close to the sealing strip corner body, and both ends of the sealing strip corner body are provided with insert strips matching the slot.

[0011] As a further solution of the utility model: the inner wall of the slot and the outer wall of the inserting strip are both provided with anti-slip patterns.

[0012] Beneficial effects of the utility model:

[0013] When the utility model assembles the sealing strip corner body, the elastic support structure composed of the compensation spring and the constraint plate can extrude the sealing strip corner body from the outside, thereby constraining its deformation range, thereby effectively avoiding excessive deformation of the sealing strip corner body, and after the extrusion is completed, it also helps the sealing strip corner body to recover its deformation, thereby further extending the service life of the sealing strip corner body, and effectively reducing the probability of separation between the two ends of the sealing strip corner body and the connecting structure; and when the sealing strip corner body is excessively extruded, the fixed plate, the compensation spring and the constraint plate are retracted into the interior of the safety groove, avoiding damage to the fixed plate, the compensation spring and the constraint plate caused by collision, thereby ensuring the normal use of the device.
