Abstract

The invention discloses a window lifter, which includes a cross-arm type glass lifter, including a main arm, an auxiliary arm, a fixed guide rail, a moving guide rail, a mounting plate and a driving mechanism for driving the main arm. The main arm is rotatably connected to the On the mounting plate, a guide rod is vertically arranged on at least one side of the moving guide rail, and a sleeve is slidably arranged on the guide rod, and the sleeve is connected to the moving guide rail through a connecting rod. Compared with the prior art, the present invention uses the connecting rod and the guide sleeve as the reinforcing part of the moving slide rail, which eliminates the disadvantage that the traditional lifter needs to set the guide slide rail in the door, so that the door fixedly connected with the moving slide rail During the lifting process of the vehicle window, even if the guide rail is not provided, the lifting effect of the vehicle window will not be affected, which is economical and practical.

Description

window regulator

technical field

The invention relates to the field of auto parts, and more specifically, to a lifter for lifting and lowering vehicle windows.

Background technique

The traditional arm lifter is shown in Fig. 1. In order to obtain a completely definite guide for the window, two guide rails 10 for guiding it must be provided inside the door. Since the window itself is not completely flat, in actual use, the two The design accuracy of the guide rail 10 is very high, and the guide rail 10 that is not processed properly will easily cause abnormal noise when the vehicle window is guided by the guide rail 10 in use. The above problems need to be solved urgently.

Contents of the invention

Aiming at the deficiencies in the prior art, the invention provides a window lifter.

The present invention is achieved through the following technical solutions: a vehicle window regulator, including a cross-arm type glass regulator, including a main arm, an auxiliary arm, a fixed guide rail, a moving guide rail, a mounting plate and a driving mechanism for driving the main arm. The main arm is rotatably connected to the mounting plate, a guide rod is vertically arranged on at least one side of the moving guide rail, and a sleeve is slidably arranged on the guide rod, and the sleeve is connected to the said guide rod through a connecting rod. Moving rail connection.

In the above technical solution, the length of the connecting rod is between 10cm and 15cm.

In the above technical solution, upwardly protruding protrusions are provided on both sides of the rotational connection between the active arm and the mounting plate, and a steel ball support mechanism is provided at the upper end of the protrusions.

In the above technical solution, an elongated through hole is opened on the raised portion.

The present invention has the following beneficial effects: the present invention uses the connecting rod and the guide sleeve as the reinforcing part of the moving slide rail, which eliminates the disadvantage that the traditional lifter needs to set the guide slide rail in the car door, so that the door fixedly connected with the moving slide rail During the lifting process of the vehicle window, even if the guide rail is not provided, the lifting effect of the vehicle window will not be affected, which is economical and practical.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments: Referring to Figures 2 to 6, the window regulator includes a cross-arm type glass regulator, including a main arm 1, an auxiliary arm 2, a fixed guide rail 3, and a moving guide rail. 4. The mounting plate 5 and the drive mechanism 6 for driving the active arm 1, the active arm 1 is rotatably connected to the mounting plate 5, the window glass is fixedly arranged on the moving guide rail 4 through the connecting piece 10, and the At least one side of the moving guide rail 4 is vertically provided with a guide rod 9, and a sleeve 8 is slidably arranged on the guide rod 9, and the sleeve 8 is connected with the moving guide rail 4 through a connecting rod 7, and the connection The length of the rod 7 is between 10cm and 15cm.

By using the connecting rod 7 and the guide sleeve 8 as the reinforcing parts of the moving guide rail 4, the disadvantage that the traditional lifter needs to be provided with a guide slide rail in the door is eliminated, so that during the lifting process of the window fixedly connected with the moving slide rail, Even if the guide slide rail is not provided, the lifting effect of the vehicle window will not be affected.

Protruding portions 50 protruding upward are provided on both sides of the rotational connection between the active arm 1 and the mounting plate 5 , and a steel ball support mechanism 51 is provided at the upper end of the protruding portion 50 . An elongated through hole 52 is opened on the protruding portion 50 .

Referring to FIG. 3 , an embodiment of the steel ball support mechanism 51 is shown in FIG. 3 , which includes a steel ball disposed on the upper end of the raised portion 50 . The steel ball makes point contact between the mounting plate 5 and the active arm 1, which reduces the noise generated by the active arm during rotation. Owing to having the convex portion 50 that protrudes upwards, and offer strip-shaped through-hole 52 on the convex portion 50, make steel ball when being pressed, the convex portion 50 between the strip-shaped through-hole 52 can Better deformation under compression, suitable springback force can be produced to make close contact between the steel ball and the mounting plate 5 .

Referring to Fig. 4 to Fig. 5, another embodiment of the steel ball support mechanism 51 is shown in Fig. Steel ball 51b is arranged in the installation sleeve 51a, the lower end of steel ball 51b is provided with the spring 51c against it, the adjustment nut 51d is screwed on the lower end of installation sleeve 51a, and the adjustment nut 51d is used to adjust the spring 51c by screwing. elastic tension.

The above examples are only specific examples of the present invention, and obviously, the present invention is not limited to the above examples. All deformations that can be directly derived or associated by those skilled in the art from the content disclosed in the present invention shall belong to the protection scope of the present invention.
