Abstract

The utility model provides a glass lifter, including installing motor on motor support, by motor drive and drive glass up-and-down linear motion's cross arm subassembly, cross arm subassembly includes short slide rail of fixed mounting on the glass face, connects long slide rail, the alternately arranged's of glass bottom master arm and slave arm, the one end of master arm pass through the rivet rotatable and motor support riveting, still the cover is equipped with stainless steel elastic washer on the center pin of rivet, stainless steel elastic washer press from both sides and establish between the nail lid of motor support and rivet, through the axial gap between stainless steel elastic washer pretension support rivet lid and the motor support, make the master arm hug closely motor support. Because the stainless steel elastic washer is additionally arranged between the motor support and the rivet, the long-term abrasion loss of the motor support in the axial direction is pre-tightened, and the driving arm is ensured to be tightly attached to the motor support at any rotation angle.

Description

Glass lifter

Technical Field

The utility model relates to a vehicle window glass lifter.

Background

The driving arm of the traditional crossed arm lifter is riveted and fixed with a motor mounting bracket by a cylindrical rivet, and rotates under the drive of a motor gear by taking a bracket rivet central shaft as a circle center, so that the circular motion of a motor output shaft is converted into the linear motion of glass. When the automobile door is opened or closed, the vibration of the glass is transmitted to the driving arm along with the long sliding chute connected to the glass, and the driving arm impacts the motor mounting bracket under the driving of the vibration source to form abnormal sound.

Disclosure of Invention

The utility model provides a can effectively solve the abnormal sound problem, prolong self or even the glass-frame riser of the whole life-span of door.

In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides a glass lifter, is including installing motor on motor support, by motor drive and drive glass up-and-down linear motion's crossing arm subassembly, crossing arm subassembly includes short slide rail of fixed mounting on the glass face, connects long slide rail, the alternately initiative arm and the follower arm that sets up in the glass bottom, the one end of initiative arm pass through the rivet rotatable and motor support riveting, still the cover is equipped with stainless steel elastic washer on the center pin of rivet, stainless steel elastic washer press from both sides and establish between the nail lid of motor support and rivet, through the axial clearance between stainless steel elastic washer pretension support rivet lid and the motor support, make the initiative arm hug closely motor support.

As an improvement: a flat gasket is arranged between the stainless steel elastic washer and the motor support in a clamping mode, so that sharp corners of the stainless steel elastic washer after being opened can be prevented from scraping the motor support.

The utility model discloses a glass-frame riser owing to increased stainless steel elasticity packing ring between motor support and rivet, pretension motor support is in the ascending long-term wearing and tearing volume of axial, guarantees under any rotation angle, and motor support is all hugged closely to the master arm.

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Fig. 2 is a schematic diagram of the exploded structure of fig. 1.

Detailed Description

As shown in fig. 1 and 2, the glass lifter provided by the present invention comprises a motor mounted on a motor support, and a cross arm assembly driven by the motor and driving glass to move linearly up and down, wherein the cross arm assembly comprises a short slide rail 5 fixedly mounted on a glass surface, a long slide rail 4 connected to the bottom of the glass, a driving arm 3 and a driven arm 6 arranged in a cross manner, one end of the driving arm is riveted with the motor support 1 through a rivet 9, the other end of the driving arm is slidably connected with the long slide rail 4 through a slider, the driven arm is arranged in a cross manner with the driving arm 3, the upper end of the driven arm is slidably connected to the short slide rail 5 through a slider, the lower end of the driven arm is slidably connected to the long slide rail 4, the rivet 9 comprises a central shaft through which the motor support 1 and one end of the driving arm pass, and a nail cover fixedly connected to one end of the central shaft, the central shaft of the rivet 9 is further sleeved with a stainless steel elastic washer 8 and a flat pad 7, the stainless steel elastic washer 8 is clamped between the motor support 1 and a rivet cover of the rivet, and the flat gasket 7 is clamped between the stainless steel elastic washer 8 and the motor support. And the gap caused by gradual abrasion between the rivet and the contact surface of the motor support can be pre-tightened by the elastic washer through proper selection of the elastic washer, so that the driving arm is tightly attached to the motor mounting support at any rotation angle. The flat cushion 7 functions as: avoid stainless steel elasticity packing ring to open back closed angle scraping motor support and form other troubles, because the area of contact of flat 7 with the motor support of filling up is big, the friction torque is little, and flat 7 of filling up is little with stainless steel elasticity packing ring area of contact, and local pressure is powerful, leads to locking relatively between flat and the bullet pad to die, and when the master arm was rotatory, flat and motor support rotated relatively, had avoided the bullet to fill up the scraping support.

Although the present invention has been described with reference to the specific embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.

Claims

1. A window regulator, characterized in that: including installing motor on motor support, by motor drive and drive glass linear motion's crossing arm subassembly from top to bottom, the crossing arm subassembly includes short slide rail (5), the long slide rail (4) of connection in the glass bottom, alternately arranged initiative arm (3) and trailing arm (6) of fixed mounting on the glass face, the one end of initiative arm (3) pass through rivet (9) rotatable and motor support (1) riveting, still the cover is equipped with stainless steel elastic washer (8) on the center pin of rivet (9), stainless steel elastic washer (8) press from both sides and establish between the nail lid of motor support (1) and rivet, through the axial clearance between stainless steel elastic washer pretension support rivet lid and the motor support, make the initiative arm hug closely motor support.

2. The window regulator of claim 1, wherein: a flat gasket (7) is also clamped between the stainless steel elastic washer (8) and the motor support, so that the sharp corner of the opened stainless steel elastic washer is prevented from scraping the motor support.
