Abstract

The utility model discloses an overturning-preventing connection device of a vehicle door glass, which comprises a rising and down block on which a one-way entering and positioning pin is arranged, an elastic reverse clasp is disposed on the one-way entering and positioning pin, and the lower part of the rising and down block is provided with a glass limiting and supporting block. The connection device is connected with the glass by the one-way entering and positioning pin, and the glass is clamped by the elastic reverse clasp on the one-way entering and positioning pin after a connecting hole on the glass threads through the one-way entering and positioning pin. When the glass is lifted and produces rotation, the glass limiting and supporting block produces an opposite moment to the glass so as to keep the balance of the glass. The structure is simple and the installation is convenient. The utility model avoids the use of multi-axial connection, and the positions of a plurality of axles have deviations when processing, which may cause a certain deviation between the connection of two axles and the ideal position, and the deviation can be amplified at other edges of the glass, thereby being unfavorable for the assembling and enhancing the friction with a weather strip, and the lifting noise will be increased.

Description

Anti-rotation connection device for door glass

technical field

The utility model belongs to a car door glass connecting device, in particular to a car door glass anti-turning connecting device.

Background technique

In the connecting structure of the door glass and the lifter, there are some structures that cannot prevent the glass from turning over during the lifting process, which affects the lifting of the door glass; at the same time, some structures that prevent the glass from turning over during the lifting process are too complicated, or the manufacturing process etc. Higher requirements.

Contents of the invention

The purpose of the utility model is to provide a simple-structured car door glass anti-turnover connection device to solve the above problems.

The technical scheme of the utility model is: the anti-turnover connection device for the door glass, which includes a lifting block, a one-way entry positioning pin is set on the lifting block, an elastic reverse buckle is set on the one-way entry positioning pin, and a glass limiter is set at the lower part of the lifting block. bit support block.

A glass removal elastic body is also arranged on the lifting block.

The connection device is connected with the glass through the one-way entry positioning pin, and after the connection hole on the glass passes through the one-way entry positioning pin, it is blocked by the elastic reverse buckle on the one-way entry positioning pin. The lower end of the glass is supported by a glass limit support block, especially an elastic block; when the glass rises and falls and rotates, the glass limit support block will generate an opposite moment to the glass to maintain the balance of the glass. The utility model has the advantages of simple structure and convenient installation. Avoiding the use of multi-axis connection, the position processing deviation between multiple axes may cause a certain deviation between the connection line of the two axes and the ideal position, which will be enlarged on the other edges of the glass, which is not conducive to assembly, enlargement and sealing The friction of the bar increases the lifting noise and other problems. Using a single axis can effectively reduce the effects of such deviations.

Detailed ways

Example 1

As shown in FIG. 1 , a guide rail 14 is provided on one side of the lifting block 1 , which is a typical structure. The other side of the lifting block 1 is provided with a one-way entry positioning pin 11, an elastic reverse buckle 110 is provided on the one-way entry positioning pin 11, and a glass removal elastic body 15 is also provided on the lifting block 1, and the glass removal elastic body 15 is located on At least one unit elastic block 15 on the lifting block, two unit elastic blocks 15 are provided in this embodiment. Lifting block 1 bottom establishes glass limit support block, and glass limit support block is an elastic block, and glass limit support block among the figure is that left and right two glass limit support blocks 12,13 are set on the same height. The effect after connecting the glass is shown in Figure 3.

Example 2

As shown in FIG. 4 , a guide rail 14 is provided on one side of the lifting block 1 , which is a typical structure. The other side of the lifting block 1 is provided with a one-way entry positioning pin 11, and the one-way entry positioning pin 11 is provided with an elastic reverse buckle 110, and the glass removal elastic body 3 is also provided on the lifting block 1, and the glass removal elastic body 3 is disc-shaped elastomer. Lifting block 1 bottom establishes glass limit support block, and glass limit support block is an elastic block, and glass limit support block among the figure is that left and right two glass limit support blocks 12,13 are set on the same height. The effect after connecting the glass is shown in Figure 6.

When the glass is installed, as shown in Figure 2 and 3, the glass moves along the axial direction of the guide column through the guide column of the positioning pin 11 through the one-way entry, (in order to facilitate installation, guide surfaces can also be provided on the elastic blocks 12 and 13), compression The elastic reverse buckle 110, after the surface 22 of the glass touches the elastic block 15, continues to move until the surface 21 crosses the non-return surface 112 on the buckle 110, the buckle 110 bounces up, and the glass is fixed. The hole 23 on the glass and the bearing pin are a kind of cooperative relationship (larger gap is shown in the figure), so as to be beneficial to reduce noise. When disassembling the glass (such as replacing the glass), the buckle 110 needs to be pressed down with a tool, and the glass 1 will withdraw under the action of the elastic body 3 or 15 .

Due to the inconsistency of the force on each edge during the lifting process of the glass, there may be a rotation trend in direction 7 or direction 8 as shown in Figure 3 . When the rotation in the direction 7 occurs, the elastic element 12 will be compressed, and the elastic element 13 will be relaxed, generating a reverse moment and maintaining the balance of the glass. vice versa.
