Description

Lifter structure for reducing car window top impact noise

Technical Field

The utility model relates to a riser structure, especially a reduce car window and dash riser structure of top noise.

Background

The glass lifter is a lifting device for automobile door and window glass, and mainly comprises an electric glass lifter and a manual glass lifter. At present, the lifting of door and window glass of many cars is generally changed into a button type electric lifting mode, an electric glass lifter is used, and the electric glass lifter for the cars mostly comprises a motor, a speed reducer, a guide rope, a guide plate, a glass mounting bracket and the like. The main switch is controlled by the driver to open and close all the glass windows, and the sub-switches on the handles in the doors are controlled by the passengers to open and close all the glass windows, so that the operation is very convenient.

When the height of the window glass of the existing window glass lifter is adjusted, when the window glass rises to a top dead center, because only the lip at the top of a vehicle door groove has a buffer structure, the sound of glass top-flushing is larger and reaches 60-65Db, and the window glass is easy to damage.

Disclosure of Invention

The utility model aims to provide a: aiming at the problem of loud sound when the window glass is pushed to the top in the prior art, the utility model provides a car window capable of reducing abnormal sound.

In order to realize the purpose of the utility model, the utility model provides a following technical scheme:

a lifter structure for reducing the noise of car window top impact comprises a lifter provided with a guide rail, wherein the guide rail is connected with a limiting slide block, the limiting slide block is provided with a clearance hole, the clearance hole is arranged towards a guide rod, and a spring is sleeved outside the guide rod; when the car window is pushed, the limiting slide block is abutted to the spring and extrudes the spring.

Adopt above-mentioned technical scheme the utility model discloses, through setting up the spring, and establish the spring housing outside the guide arm, and the guide arm sets up towards spacing slider's clearance hole, therefore, at the last one section distance that the door window dashes the top, spacing slider can with the spring butt, the effect is exerted to spacing slider to the spring for spacing slider's the speed of dashing the top slows down, plays the effect of buffering, so that reduce the abnormal sound when the door window is closed, reduces the noise that the door window closed the in-process and produce.

Further, the top of the guide rod is fixed on the flanging of the lifter guide rail. The guide rod is matched with the clearance hole of the limiting slide block, and a buffering effect is generated through the spring, so that the guide rod can be arranged beside the lifter.

Furthermore, lubricating grease is coated between the guide rod and the spring. The friction force between the spring and the guide rod when the length of the spring is changed is reduced, and then the noise generated between the spring and the guide rod is reduced.

Furthermore, the limiting slide block is clamped on the guide rail. The clamping connection is realized, and the production, writing and maintenance are convenient.

Furthermore, the clearance hole is a blind hole, and the inner diameter of one end close to the guide rod is larger. The guide rod can be conveniently inserted into the clearance hole.

Furthermore, two lifters are arranged on the car window in parallel; each lifter is connected with a limiting slide block.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: through setting up the spring, and establish the spring housing outside the guide arm, and the guide arm sets up towards spacing slider's clearance hole, therefore, at the last one section distance that the door window dashes the top, spacing slider can with the spring butt, the effect is exerted to spacing slider by the spring for spacing slider's the speed of dashing the top slows down, plays the effect of buffering, so that reduce the abnormal sound when the door window is closed, reduces the noise that the door window closed the in-process and produce.

Detailed Description

It is noted that, unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1 and 2, a lifter structure for reducing the noise generated by the top impact of a car window comprises a lifter 10 provided with a guide rail, wherein the guide rail is connected with a limiting slide block 20, the limiting slide block 20 is provided with a clearance hole 21, the clearance hole 21 is arranged towards a guide rod 30, and a spring 40 is sleeved outside the guide rod 30; when the vehicle window is pushed, the limiting slide block 20 is abutted with the spring 40 and presses the spring 40.
