Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vehicle door glass guide rails, in particular to a left front door glass upper guide rail with a noise reduction structure. Background Art
[0002] The front door glass guide is an important part of the car window system, responsible for guiding the movement of the window glass during the lifting process. It is usually installed inside the door and works with the window glass lifter to ensure that the window glass can be lifted and lowered smoothly.
[0003] At present, the structure of the door rail is mainly composed of the rail base and the rail rubber body. However, as time goes by, the door seal will inevitably age. Once the seal is aged, moisture from the outside may penetrate into the rail as the window is raised and lowered. This moisture retention will not only increase the friction coefficient, thus affecting the smooth lifting and lowering of the window, but may also corrode the rail rubber body, further shortening its service life. In addition, as the rail rubber body ages, its surface will gradually become rough and uneven. This surface roughening will not only reduce the smoothness of the window lifting and lowering, but may also produce harsh noise during the window lifting and lowering process, which will seriously affect the riding comfort.
[0004] Therefore, it is very necessary to invent a left front door glass upper guide rail with a noise reduction structure. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a left front door glass upper guide rail with a noise reduction structure, comprising a guide rail shell, a fixing piece, a rubber sealing lining, a door glass and a high-performance filling body, wherein the fixing piece is symmetrically fixedly installed on the outside of the guide rail shell, and the rubber sealing lining is fixedly installed on the inside of the guide rail shell, and the door glass is slidably installed in the rubber sealing lining, and the rubber sealing lining is filled with two high-performance filling bodies;
[0006] The rubber sealing lining includes a guide rail lining body, a positioning boss, an inner lip, an outer lip and noise reduction moisture holes. The guide rail lining body is fixedly installed inside the guide rail outer shell. The inner side of the guide rail lining body is symmetrically provided with positioning bosses, and one side of the positioning boss is provided with an inner lip and an outer lip. The inner lip and the outer lip are correspondingly provided with noise reduction moisture holes, and the two rubber sealing liners are respectively filled in the inner lip and the outer lip.
[0007] Preferably, the guide rail lining, positioning boss, inner lip and outer lip are an integrated structure, all made of high-strength rubber, and a sliding groove is formed between the positioning boss, inner lip and outer lip to allow the door glass to slide.
[0008] Preferably, the noise reduction moisture holes formed on the inner lip and the outer lip are composed of horizontal holes and inclined holes, and the slide groove formed by the positioning protrusion, the inner lip and the outer lip is connected to the area where the high-performance filling body is located through the noise reduction moisture holes.
[0009] Preferably, the high-performance filling body is made of a porous material, a diaphragm and a water-absorbing material. The diaphragm is arranged between the porous material and the water-absorbing material, and sound-absorbing holes are distributed in a rectangular array on the surface. The water-absorbing material is in contact with the inner surface of the inner lip or the inner surface of the outer lip, and the porous material is in contact with the guide rail lining or the positioning boss.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] The rubber sealing lining in the utility model is cleverly provided with noise-reducing moisture holes on the inner and outer lips, which are divided into two types: horizontal holes and inclined holes, each of which plays an important role. The design of the horizontal holes not only helps the noise to be effectively absorbed and processed by the high-performance filler, thereby significantly improving the quietness of the car; at the same time, it also avoids the concentration of stress to a certain extent, and improves the durability and stability of the lip. It not only meets the needs of noise reduction, but also ensures the reliability of the structure. The inclined holes focus on dealing with the moisture remaining on the surface of the door glass. They can quickly guide the moisture outflow to prevent the moisture from being retained inside the guide rail for a long time. The outflowing moisture is then absorbed by the high-performance filler, thereby keeping the inside of the guide rail dry and clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] As attached Figure 1 To Attachment Figure 3 As shown:
[0020] The utility model provides a left front door glass upper guide rail with a noise reduction structure, comprising a guide rail shell 1, a fixing part 2, a rubber sealing lining 3, a door glass 4 and a high-performance filling body 5, wherein the fixing part 2 is symmetrically fixedly installed on the outside of the guide rail shell 1, the rubber sealing lining 3 is fixedly installed on the inside of the guide rail shell 1, the door glass 4 is slidably installed in the rubber sealing lining 3, and the rubber sealing lining 3 is filled with two of the high-performance filling bodies 5.
[0021] The rubber sealing lining 3 includes a guide rail lining body 31, a positioning boss 32, an inner lip 33, an outer lip 34 and noise reduction moisture holes 35. The guide rail lining body 31 is fixedly installed inside the guide rail outer shell 1. The inner side of the guide rail lining body 31 is symmetrically provided with positioning bosses 32, and one side of the positioning boss 32 is provided with an inner lip 33 and an outer lip 34. Noise reduction moisture holes 35 are correspondingly opened on the inner lip 33 and the outer lip 34. The two rubber sealing liners 3 are respectively filled in the inner lip 33 and the outer lip 34. The guide rail lining body 31 is firmly installed inside the guide rail outer shell 1, providing stable support for the entire lining structure. The door glass 4 can easily slide in the rubber sealing lining 3, ensuring the smoothness of the window lifting and lowering.
[0022] Embodiment 1:
[0023] Specifically, the guide rail lining body 31, the positioning protrusion 32, the inner lip piece 33 and the outer lip piece 34 are an integrated structure, all made of high-strength rubber, and a slide groove allowing the door glass 4 to slide is formed between the positioning protrusion 32, the inner lip piece 33 and the outer lip piece 34. The positioning protrusion 32 is provided so that the inner lip piece 33 and the outer lip piece 34 can be accurately positioned at a specific position of the guide rail lining body 31, forming a slide groove allowing the door glass 4 to slide.
[0024] Specifically, the noise reduction moisture holes 35 opened on the inner lip 33 and the outer lip 34 are composed of horizontal holes and inclined holes. The slide groove formed by the positioning boss 32, the inner lip 33 and the outer lip 34 is connected with the area where the high-performance filler 5 is located through the noise reduction moisture holes 35. The horizontal holes help the noise to be absorbed by the high-performance filler while avoiding stress concentration; while the inclined holes can quickly guide the moisture to flow out and prevent the moisture from being retained inside the guide rail for a long time.
[0025] Specifically, the high-performance filler 5 is made of porous material, diaphragm and water-absorbing material. This combination enables the filler to have excellent sound absorption performance and effectively absorb and process residual moisture. The setting of the diaphragm enables the porous material and the water-absorbing material to work together to achieve the maximum effect. The diaphragm is set between the porous material and the water-absorbing material, and a rectangular array of sound-absorbing holes is distributed on the surface. The water-absorbing material contacts the inner surface of the inner lip 33 or the inner surface of the outer lip 34, and the porous material contacts the guide rail lining 31 or the positioning protrusion 32. The presence of the high-performance filler 5 not only further improves the noise reduction performance of the guide rail, but also ensures the dryness and cleanliness of the inside of the guide rail.
[0026] Embodiment 2:
[0027] First, when the door glass 4 slides in the rubber sealing lining 3, the noise generated during the window lifting process can be effectively reduced due to the noise reduction moisture hole 35 structure designed. These holes are composed of horizontal holes and inclined holes. The horizontal holes help the noise to be absorbed by the porous material in the high-performance filler 5, thereby reducing the noise level. At the same time, the design of the horizontal holes can also avoid stress concentration to a certain extent and enhance the stability of the structure. Next, when there is residual moisture on the surface of the door glass, the moisture will be quickly guided out by the inclined holes to prevent the moisture from being retained inside the guide rail for a long time. The outflowing moisture is then absorbed by the water-absorbing material in the high-performance filler 5, thereby keeping the inside of the guide rail dry and clean. In this process, the high-performance filler 5 plays a key role. Its diaphragm setting enables the porous material and the water-absorbing material to work together. The porous material can absorb and disperse the noise, while the water-absorbing material can effectively absorb and process the residual moisture. This combination enables the high-performance filler to have both excellent noise reduction performance and effective prevention of moisture retention. In addition, the design of the rubber sealing lining 3 also fully considers the stability and durability of the structure. The guide rail lining body 31, the positioning boss 32, the inner lip piece 33 and the outer lip piece 34 are made of high-strength rubber to form an integrated structure, thereby ensuring the stability and durability of the entire lining structure.
[0028] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
