Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and particularly relates to a self-adjusting slider mechanism for a window lifter of a flush side window and related equipment. Background Art

[0002] The statements herein only provide the background art related to the present invention and do not necessarily constitute the prior art.

[0003] With the higher demand of users for comfort, there have emerged many frameless door side window system mechanisms and flush side window system mechanisms. The Y-direction surface difference between the side windows and the cover plates of the whole vehicle model is designed to be 0 mm, making the side of the whole vehicle window system present a mirror effect, improving the smoothness and high-class sense of the appearance of the whole vehicle. At the same time, in the case of high-speed driving, such flush windows are more conducive to the air guiding effect, effectively reducing the wind noise and the wind resistance system coefficient of the whole vehicle. Considering both the appearance effect and energy saving of the whole vehicle, it has very good application prospects.

[0004] Following the development of this trend, the flush side window system has been highly applied in C-class sedans / SUVs / MPVs. However, for the side window systems of the above models, the glass has a large X-direction dimension width, which poses a very great challenge to the layout of the lifting mechanism. How to meet the balance of the resistance of the lifting system with a large width (such as a side window with an X-direction width > 820 mm) and the deflection stability during the window lifting process puts forward higher requirements for the mechanism layout of the window lifter. The single-rail mechanism window lifter of the traditional flush window cannot meet the above requirements.

[0005] If the window lifter is arranged as a double-rail mechanism, there is a difference in the relative height in the Z direction between the A / B sliders. When the glass is clamped to the slider connection of the window lifter, it will drive the glass to have a deflection force F in the X direction, forming an overconstraint condition with the X-direction limit sliding slider of the flush side window glass, resulting in difficult lifting or stuck lifting phenomena. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the purpose of the embodiments of the present invention is to provide a self-adjusting slider mechanism for a window lifter of a flush side window, a flush side window structure, a door and a vehicle, so as to solve the problem that the existing double-rail lifting system has overconstraint, resulting in difficult lifting or stuck lifting of the side window glass.

[0039] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further descriptions of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0040] Embodiment 1

[0041] In the structural layout of the flush window lifting system, restrictive conditions are put forward for the weight of the glass and the width dimension in the X direction. For example, setting the self-gravity of the glass as G, the friction resistance of the guide groove and the water stop strip of the system as f1, and the internal consumption of the lifter mechanism as f2. Then, during the upward movement of the window, the system load is: F1 = G + f1 + f2, and during the downward movement, the system load is: F2 = f1 + f2 - G. When the force of F2 is negative, the entire window lifting system shows an unstable state of lifting and lowering.

[0042] The existing window lifters for flush side windows cannot be applied to side door glasses with a larger width, and cannot ensure the deflection stability and the balance of lifting resistance during the window lifting process. To solve the above technical problems, this embodiment proposes a self-adjusting slider mechanism for a flush side window, which increases the force value f2 of the internal consumption in the window lifter mechanism during the window lifting process, balances the resistance F2 of the lifting system, and at the same time, restricts the deflection amount in the X direction of the over-wide glass, so as to ensure the rotational stability of the glass during the lifting process.

[0043] Combined with Figures 1-7 , the self-adjusting slider mechanism for a flush side window includes a first self-adjusting slider mechanism and a second self-adjusting slider mechanism installed at the bottom end of the side door glass, and a limit sliding mechanism installed on one side of the side door glass; the first self-adjusting slider mechanism performs Z-direction constraint fixation on the side door glass, the second self-adjusting slider mechanism releases the over-constraint in the Z direction and the X direction of the side door glass, and the limit sliding mechanism is close to the B-pillar and performs X-direction limit on the side door glass.

[0044] As Figure 2 shown, the limit sliding mechanism is a rugby ball-shaped slider mechanism 1. The rugby ball-shaped slider mechanism 1 includes a first slider and a second slider. The first slider is fixed along the Z direction on one side of the side door glass. One side of the first slider in the width direction is connected to one side of the second slider in the width direction. An obtuse angle is formed between the first slider and the second slider, and the first slider and the second slider are an integral mechanism; the other side of the second slider in the width direction has a protrusion, and the protrusion is located on the upper surface and the lower surface of the second slider; there is a guide groove arranged along the Z direction on the door frame. The guide groove includes a cylindrical guide rail, and an opening for the second slider to extend into is opened on one side of the cylindrical guide rail. One side of the second slider extends into the cylindrical guide rail through the opening and is slidably connected with the cylindrical guide rail; a first limit plate in the X direction is arranged on one side of the opening, and a second limit plate in the Y direction is arranged on the other side of the opening. There is a moving space for the first slider and the second slider between the first limit plate and the second limit plate, and X / Y direction constraint limits are formed on the premise of satisfying the lifting and sliding of the rugby ball-shaped slider mechanism 1.

[0045] As Figures 3-4As shown in the figure, a first lower bracket 2 and a second lower bracket 3 are installed at the bottom end of the side door glass. A first lifting track and a second lifting track are correspondingly installed on the door frame and the first lower bracket 2 and the second lower bracket 3. A lifting motor is installed on the first lifting track; the first lower bracket 2 has a plurality of first reinforcing ribs 4, and the plurality of first reinforcing ribs 4 are evenly distributed along the width direction of the first lower bracket 2. The first lower bracket 2 is provided with a waist-shaped hole; the second lower bracket 3 has a plurality of second reinforcing ribs 7, and the plurality of second reinforcing ribs 7 are evenly distributed along the width direction of the second lower bracket 3; the first self-adjusting slider mechanism includes a first lifting slider 6. The top end of the first lifting slider 6 is connected with a claw structure 5. The claw structure 5 includes a claw main board and a clamping plate. One end of the clamping plate is connected to the claw main board. A claw space is formed between the clamping plate and the claw main board. The other end of the clamping plate has a limiting protrusion; the first lower bracket 2 extends between the claw main board and the clamping plate, and the limiting protrusion is clamped with the claw main board through the waist-shaped hole; the inner side surface of the first lifting slider 6 is slidably connected with the first lifting track, and the lifting motor is connected with the first lifting slider 6 through a steel wire rope to drive the first lifting slider 6 to lift and lower; the second self-adjusting slider mechanism includes a second lifting slider 9, a sliding claw mechanism 10 and a release pin 12. Two longitudinal waist-shaped holes 11 are spaced apart from each other at the top end of the second lifting slider 9. A transverse waist-shaped hole is provided at the bottom end of the second lifting slider 9. A locking bolt 8 passes through the longitudinal waist-shaped hole and the second lower bracket 3 and is locked to fix the second lifting slider 9 to the second upper bracket. The release pin 12 passes through the transverse waist-shaped hole and the sliding claw mechanism 10 to install the sliding claw mechanism 10 on the second lifting slider 9. The sliding claw mechanism 10 is clamped to the second lifting track and is slidably connected with the second lifting track. The lifting motor is connected with the second lifting slider 9 through a steel wire rope to drive the second lifting slider 9 to lift and lower.

[0046] In this embodiment, the major axis length of the longitudinal waist-shaped hole 11 is 6 mm, the major axis length of the transverse waist-shaped hole is 6 mm, the major axis length of the waist-shaped hole is 6 mm, and the X-direction width of the side window glass is greater than 820 mm.

[0047] The assembly method of the lifter self-adjusting slider mechanism for the flush side window in this embodiment is as follows:

[0048] First, insert the first lower bracket 2 of the side door glass into the clamping main board and the clamping plate for clamping and fixing, and perform Z-direction constraint fixing through the clamping mechanism. At this time, the attitude of the side door glass is only limited by the X-direction constraint of the rugby-shaped slider mechanism 1 pasted on the B-pillar side of the glass; then, place the second lifting slider 9 on the second lower bracket 3 of the side door glass, and adjust the position of the second lifting slider 9 within the range of the longitudinal waist-shaped hole 11 and the transverse waist-shaped hole according to the actual assembly situation. After releasing the Z-direction over-constraint and X-direction over-constraint of the side door glass, pass the locking bolt 8 through the longitudinal waist-shaped hole 11 of the second lifting slider 9 and the installation through-hole on the second lower bracket 3 that matches the locking bolt 8 for locking, and pass the release pin 12 through the transverse waist-shaped hole and the second lower bracket 3 to fix the second lifting slider 9 to the second lower bracket 3; since the second lifting slider 9 has two longitudinal waist-shaped holes (Z-direction waist-shaped holes), there is an adjustment amount of ±3 mm between the locking bolt 8 and the longitudinal waist-shaped hole 11. At this time, the Z-direction over-constraint condition of the side door glass can be released, and after it is in the natural state, it can be locked by the locking bolt 8; at the same time, the second lifting slider 9 has 1 transverse waist-shaped hole (X-direction waist-shaped hole), and the release pin 12 and the transverse waist-shaped hole form a clearance fit of ±3 mm to release the over-binding force in the X-direction.

[0049] During the lifting process of the side door glass, the lifting motor starts to drive the first lifting slider 6 and the second lifting slider 9 to slide along the guide rail. The Z-direction constraint is locked, and the overall X-direction has an adjustment amount of ±3 mm. The glass can slide and adjust in the X-direction, and the Y-direction surface difference depends on the constraint of the rugby-shaped slider mechanism 1 of the side door glass, forming an integral "double-guide rail lifter system for a flush side window structure", which can ensure the moment balance during the lifting process of the glass and the deflection stability during the lifting process, and improve the smooth and reliable movement of the lifting system.

[0050] Furthermore, the surface of the release pin 12 can be coated with a grease coating to reduce the sliding resistance performance.
