Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to a window glass hanging structure without step difference. Background Art

[0002] The zero-step window glass installation structure mainly positions the door glass in the X and Y directions in the groove through the guide slider glued to it and enables it to slide in the Z direction, so that the glass surface can be flush with the surface of the decorative panel, achieving a zero-step difference effect, thereby reducing the wind resistance and wind noise on the outside of the car body and improving the NVH performance.

[0003] To reduce sliding resistance within the glass run channel, smoother lifting and lowering of the window glass, and mitigate the difficulty of raising the window glass due to air resistance inside the door during the raising process, existing manufacturers typically add a tapered or curved surface to the upper end of the guide slider located within the glass run channel. This design increases the overall mass of the guide slider and makes it prone to jitter during raising and lowering, resulting in noise and vibration of the window glass. Furthermore, this design increases the overall length of the guide slider, which in turn increases the required length of the glass run channel, necessitating the addition of several weight-reducing holes in the door for weight balance. Summary of the Invention

[0004] To solve the above problems, the present invention provides a vehicle window glass hanging structure without step difference, which is achieved as follows:

[0005] A vehicle window glass hanging structure without step difference is arranged in a vehicle door, comprising a decorative panel and an interior panel arranged at intervals inside the lower edge of the window frame of the vehicle window glass, a glass guide groove being slidably provided between the decorative panel and the interior panel, a guide slider being slidably provided in the glass guide groove, the vehicle window glass being bonded to the guide slider by glass glue, a sheet metal component being embedded in the decorative panel and the interior panel, and the glass guide groove being attached to the surface of the sheet metal component,

[0006] The decorative plate is provided with a mounting portion on one side close to the window glass, and a surface of the decorative plate on one side close to the sheet metal component extends toward the sheet metal component to form a limiting portion;

[0007] The sheet metal component extends around the limiting portion toward a side close to the window glass to form a shock absorbing portion, and the shock absorbing portion, the attachment portion, and the limiting portion form a mounting groove for accommodating the glass run channel;

[0008] The glass run channel includes a channel body portion sleeved in the mounting groove, a side of the channel body portion away from the channel body portion extending toward the interior trim panel to form a fixing portion, and the fixing portion and the interior trim panel are mutually engaged;

[0009] The guide slider includes a long sliding portion that is slidably mounted in the groove body portion, the upper end of the sliding portion extends toward the direction close to the vehicle window glass to form a connecting portion, and the vehicle window glass is bonded to the connecting portion by glass glue. A plurality of silent noise reduction units are arranged along a longitudinal array on the outer wall of one side of the upper end of the sliding portion away from the connecting portion.

[0010] As a further improvement, each of the silent noise reduction units is a curved strip-shaped protrusion that passes around the upper end side wall surface of the sliding portion.

[0011] As a further improvement, the plurality of said silent noise reduction units include a plurality of sealing and dustproof units and a plurality of shock absorbing units;

[0012] Several of the sealing and dustproof units are arranged gradually sparsely from bottom to top, and several shock-absorbing units are respectively filled between two adjacent sealing and dust-proof units. The sealing and dust-proof units are attached to the inner wall of the groove body, and the shock-absorbing units are not attached to the inner wall of the groove body.

[0013] As a further improvement, a plurality of air passage grooves are provided on the plurality of the sealing and dustproof units in a vertical direction, and the air passage grooves between the plurality of the sealing and dustproof units are staggered with each other.

[0014] As a further improvement, the openings at the upper and lower ends of the air passage groove gradually shrink toward opposite directions.

[0015] As a further improvement, the vertical cross-section of the sealing dustproof unit is a geometric shape consisting of two upper and lower arcs, and the curvature of the upper arc of the cross-section of the sealing dustproof unit is greater than the curvature of the lower arc of the cross-section of the sealing dustproof unit;

[0016] The vertical cross section of the shock absorbing unit is in a semicircular arc shape.

[0017] As a further improvement, the vertical cross-sections of several of the mute and noise reduction units are rack-shaped.

[0018] As a further improvement, the glass run channel is integrally injection-molded from glass fiber reinforced polypropylene with a glass fiber content of 30%, long glass fiber reinforced polypropylene with a long glass fiber content of 30%, or nylon with a glass fiber content of 30%.

[0019] The beneficial effects of the present invention are:

[0020] 1. By arranging a number of silent noise reduction units along a longitudinal array on the outer wall of the upper end of the guide slider away from the connection portion, after the array is arranged with multiple units, compared with the traditional surface-to-surface contact between the guide slider and the glass run channel, it is converted to multi-point contact or line contact, the contact area is smaller, and the resistance generated during the rising and falling process is correspondingly smaller. Therefore, there is no need to add a gradually shrinking guide part, which reduces the overall structure of the guide slider without affecting its original effect.

[0021] 2. The silent noise reduction unit protruding from the upper side wall surface of the guide slider has higher rigidity, and is less likely to vibrate and cause noise during the rising and falling process, while ensuring that the rising and falling process of the window is smoother.

[0022] 3. By providing a silent noise reduction unit, the side wall is actually processed to form a raised silent noise reduction unit, thereby reducing the overall weight of the guide slider and further optimizing the performance of the car door. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0027] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0028] A step-free window glass mounting structure is provided inside a vehicle door and comprises a decorative panel 2 and an interior panel 3 spaced apart and arranged inside the lower edge of the window frame of the vehicle window glass 0. A glass guide groove 4 is slidably provided between the decorative panel 2 and the interior panel 3. A guide slider 1 is slidably provided in the glass guide groove 4. The vehicle window glass 0 is bonded to the guide slider 1 by glass glue. A sheet metal component 5 is also embedded in the decorative panel 2 and the interior panel 3. The glass guide groove 4 is attached to the surface of the sheet metal component 5.

[0029] The decorative plate 2 is formed with a mounting portion 21 on a side close to the vehicle window glass 0, and a surface of the decorative plate 2 is formed with a side close to the sheet metal component 5 and extends toward the sheet metal component 5 to form a limiting portion 22;

[0030] The sheet metal component 5 extends around the limiting portion 22 toward the side close to the window glass 0 to form a shock absorbing portion, and the shock absorbing portion, the attachment portion 21 and the limiting portion 22 form a mounting groove for accommodating the glass run channel 4;

[0031] The glass run channel 4 includes a groove portion 41 sleeved in the mounting groove, and a side of the groove portion 41 away from the groove portion 41 extends toward the interior panel 3 to form a fixing portion 42, and the fixing portion 42 is engaged with the interior panel 3;

[0032] The guide slider 1 includes a long sliding portion 11 that is slidably mounted in the groove portion 41. The upper end of the sliding portion 11 extends toward the direction close to the vehicle window glass 0 to form a connecting portion 12. The vehicle window glass 0 is bonded to the connecting portion 12 by glass glue. A plurality of silent noise reduction units 13 are arranged along a longitudinal array on the outer wall of one side of the upper end of the sliding portion 11 away from the connecting portion 12.

[0033] As a further improvement, each of the noise reduction units 13 is a curved strip-like protrusion that winds around the upper sidewall surface of the sliding portion 11. These curved strip-like protrusions can create a wavy vertical cross-section of the upper portion of the guide slider 1. This curved surface provides enhanced force dispersion. Furthermore, the wavy shape allows the guide slider 1 to form a series of linear contacts with the inner wall of the glass run, preventing guide slider 1 from deflecting while reducing the contact area and friction during ascent and descent.

[0034] To further reduce friction between the guide slider 1 and the glass run, as a further improvement, the plurality of silent noise reduction units 13 include a plurality of sealed dustproof units and a plurality of shock-absorbing units. The sealed dustproof units are arranged gradually more sparsely from bottom to top, and the shock-absorbing units are respectively filled between two adjacent sealed dustproof units. The sealed dustproof units are attached to the inner wall of the groove body 41, while the shock-absorbing units do not adhere to the inner wall of the groove body 41. The sealed dustproof units prevent dust from entering the interior, while the shock-absorbing units buffer the vibration caused by friction during the ascent and descent process, making the guide slider 1 more stable as a whole during the ascent and descent process.

[0035] To further reduce friction between the guide slider 1 and the glass run, and to avoid obstacles to ascent and descent caused by internal air pressure, several of the sealed dustproof units are provided with vertically disposed air passages, with the air passages staggered between the units. This staggered arrangement prevents dust from directly falling onto the bottom of the guide slider 1, potentially accumulating on the lifting mechanism and hindering its movement.

[0036] In order to improve the pressure relief capability of the air passage groove, as a further improvement, the openings at the upper and lower ends of the air passage groove gradually shrink toward opposite directions.

[0037] In order to reduce the air resistance during the ascent and descent process, as a further improvement, the vertical cross-section of the sealed dustproof unit is a geometric shape consisting of two upper and lower arcs, and the curvature of the upper arc of the cross-section of the sealed dustproof unit is greater than the curvature of the lower arc of the cross-section of the sealed dustproof unit;

[0038] The vertical cross section of the shock absorbing unit is semicircular;

[0039] The sealing and dustproof unit located at the lower end is arranged in reverse.

[0040] In another embodiment, the vertical cross-sections of the plurality of the mute noise reduction units 13 are rack-shaped.

[0041] In another embodiment, the plurality of mute noise reduction units 13 are a plurality of dot-shaped protrusions.

[0042] As a further improvement, the glass run channel 4 is integrally injection-molded from glass fiber reinforced polypropylene with a glass fiber content of 30%, long glass fiber reinforced polypropylene with a long glass fiber content of 30%, or nylon with a glass fiber content of 30%.

[0043] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
