Description

Technical Field

[0001] This invention relates to a glass run installed in the door frame of a vehicle, such as an automobile. Background Technology

[0002] Improving the quietness of vehicles such as cars enhances passenger comfort, thereby increasing product appeal and attention. Furthermore, electric vehicles, which are expected to rapidly become widespread, lack current engines. Therefore, while engine noise is eliminated, road noise and wind noise—the main sources of noise—become more noticeable. Consequently, the necessity for noise reduction technologies has increased further compared to current practices.

[0003] The sound of wind breaking is the sound produced when the wind comes into contact with the vehicle while it is moving, which travels through the vehicle body to the interior. Regarding this transmission path, it is known that the door glass, which is closest to the ears of the occupants inside the vehicle, plays the most important role. Countermeasures such as increasing the thickness of the door glass and setting up acoustic glass have been taken, but the increased weight and cost have become obstacles.

[0004] However, apart from the door glass, research was conducted on increasing the noise reduction effect of the glass groove, which serves as a seal between the door glass and the door frame, especially in the high-frequency range of 1 kHz or higher.

[0005] like Figure 7 As shown, the glass slide 110 is formed in a tunnel shape (cross-section is "ko") with the bottom wall 200, the outer side wall 300, and the inner side wall 400 as the basic framework. A cover lip 340 is formed at the front end of the outer side wall 300 to abut against the door glass 600. On the inner side of the outer side wall 300, which is closer to the bottom wall 200 than the cover lip 340, an outer sealing lip 330 is formed that protrudes toward the bottom wall 200 and slides in contact with the door glass 600.

[0006] On the other hand, an inner-side first sealing lip 410 is formed at the front end of the inner-side sidewall 400, which slides in contact with the door glass 600. A secondary lip 420, protruding in the opposite direction to the inner-side first sealing lip 410, is formed on the outer side of the inner-side sidewall 400, closer to the bottom wall 200 than the inner-side first sealing lip 410, facing outwards. When the inner-side first sealing lip 410 slides in contact with the door glass 600, the inner side of the inner-side first sealing lip 410 abuts against the secondary lip 420. Furthermore, a cover lip 430 is formed at the front end of the inner-side sidewall 400, which extends in such a way that the inner-side frame of the door frame 310 is sandwiched between the inner-side sidewall 400 and the inner-side sidewall 400 (Patent Document 1).

[0007] As a noise reduction technology based on glass slides, the technology described in Patent Document 2 below is known, for example. Patent Document 2 relates to... Figure 7 Arrow A indicates that the glass slide passes through the track. Furthermore, the same reference numerals are used for common parts as in Patent Document 1.

[0008] Regarding the glass groove 110 in Patent Document 2, such as Figure 8 As shown, the inner sealing lip of the vehicle has: a first inner sealing lip 410; and a second inner sealing lip 440, which is formed to be closer to the bottom wall 200 than the first inner sealing lip 410. The first inner sealing lip 410 and the second inner sealing lip are formed facing the bottom wall 200, and do not abut against each other when sliding in contact with the door glass 600.

[0009] As a result, the glass slide 110 has: a first sealing lip 410 on the inner side of the vehicle; and a plurality of second sealing lips 440 on the inner side of the vehicle, which are formed to be closer to the bottom wall 200 than the first sealing lip on the inner side of the vehicle. Therefore, the shielding effect of the glass slide through the track is increased, and noise can be reduced.

[0011] Patent Document 2: Japanese Patent Application Publication No. 2021-24388 Summary of the Invention

[0012] However, regarding techniques to reduce noise caused by wind noise, there is another method that can reduce vibration by using so-called impedance matching, which effectively directs the vibration energy of the door glass to flow and dissipate towards the components that come into contact with the door glass. However, this has not been adequately studied at present.

[0013] This invention focuses on impedance matching and provides a glass channel that can effectively dissipate the vibration energy of the car door glass and reduce noise caused by wind noise.

[0014] To solve the above problems, the present invention, technical solution 1, is a glass slide channel, which uses a bottom wall, an outer side wall of the vehicle, and an inner side wall of the vehicle as a basic frame. The basic frame is installed in the door frame groove formed in the door frame to guide the raising and lowering of the door glass. The glass slide channel is characterized in that a thick wall portion is formed on the inner side of the outer side wall of the vehicle. This thick wall portion protrudes towards the inner side of the vehicle and slides in contact with the door glass, and its hardness is higher than that of the main body of the outer side wall of the vehicle.

[0015] In the present invention, technical solution 1, a thick-walled portion protruding inward and slidingly contacting the door glass is formed on the inner side of the outer sidewall of the glass channel. Therefore, compared with the outer sealing lip of the prior art, the rigidity of the glass channel is increased, and the vibration energy of the door glass can be effectively dissipated when sliding in contact with the door glass. As a result, noise caused by wind noise can be reduced.

[0016] Furthermore, the hardness of the thick-walled section is higher than that of the main body of the outer sidewall of the vehicle, thus further increasing the rigidity of the glass slide. As a result, the thick-walled section of the glass slide can effectively dissipate the vibration energy of the door glass, reducing noise caused by wind noise.

[0017] Here, "the rigidity of the glass slide" is represented by the increase in the amount of displacement of the pressing part when the door glass presses against the glass slide relative to the reaction force from the glass slide. Therefore, "increased rigidity of the glass slide" means that the slope (gradient) of the relationship between displacement and reaction force increases.

[0018] Regarding impedance matching between the door glass and the glass track, it can be considered that the impedance of the door glass is governed by its mass, while the impedance of the glass track is governed by its rigidity. In the high-frequency range of 1kHz or higher, where noise reduction from the glass track is expected, the impedance of the door glass is greater than that of the glass track. Therefore, it can be argued that if the rigidity of the glass track can be increased to make its impedance close to or equal to that of the glass, impedance matching can effectively allow the vibrational energy of the door glass to flow and dissipate towards the glass track, thus reducing noise caused by wind noise.

[0019] The present invention described in technical solution 2 is based on the invention of technical solution 1, characterized in that an inner sealing lip is formed on the inner side wall of the vehicle. The inner sealing lip extends from the front end of the inner side wall or from the outer side of the vehicle between the front end of the inner side wall and the bottom wall towards the outer side of the vehicle and towards the bottom wall. The outer side of the vehicle slides in contact with the door glass. When the door glass slides in contact with the thick wall and the inner sealing lip and is raised and lowered, the reaction force from the outer side and the inner side of the vehicle on the door glass is greater than the reaction force from the outer side.

[0020] In the present invention described in technical solution 2, an inner sealing lip is formed on the inner sidewall of the vehicle. This inner sealing lip extends from the front end of the inner sidewall or from the outer side of the inner sidewall between the front end and the bottom wall towards the outer side of the vehicle and towards the bottom wall. The outer side of the vehicle slides in contact with the door glass. When the door glass slides and rises / falls in contact with the thick wall portion and the inner sealing lip, it experiences reaction forces from both the outer and inner sides of the vehicle. The reaction force from the inner side is greater than the reaction force from the outer side, thus increasing the pressure of the door glass against the thick wall portion. This allows the door glass to displace towards a position where the rigidity of the glass channel increases. As a result, the vibration energy of the door glass can be effectively dissipated towards the glass channel, further reducing noise caused by wind noise.

[0021] In the invention of technical solution 3, which is based on technical solution 1 or technical solution 2, a convex rib is formed on the inner surface of the thick-walled part of the vehicle.

[0022] In the present invention of technical solution 3, a convex rib is formed on the inner surface of the thick-walled part, which can prevent dust, dirt, foreign objects, etc. from getting stuck in the thick-walled part when the door glass is raised or lowered, and prevent the generation of abnormal noises associated with it.

[0023] Based on the invention of technical solution 1 or technical solution 2, the invention of technical solution 4 forms an outer sealing lip on the outer side wall of the vehicle. The outer sealing lip extends from the front end of the outer side wall or the inner side of the outer side wall between the front end of the outer side wall and the bottom wall towards the inner side of the vehicle and towards the bottom wall. The inner side of the vehicle slides in contact with the door glass, and the outer sealing lip does not abut against the thick wall portion.

[0024] In the present invention of technical solution 4, an outer sealing lip is formed on the outer sidewall of the vehicle. This outer sealing lip extends from the front end of the outer sidewall or from the inner side between the front end of the outer sidewall and the bottom wall towards the inner side and towards the bottom wall. The inner side of the lip slides in contact with the door glass, thus improving the sealing performance relative to the door glass and preventing the intrusion of raindrops, dust, etc., and enabling the glass slide channel to pass through the track (…). Figure 7 The noise of arrow A in the image is reduced.

[0025] Furthermore, the outer sealing lip does not abut against the thick-walled section, allowing the vibrational energy of the door glass to flow and dissipate effectively when the thick-walled section slides into contact with the door glass. As a result, noise caused by wind noise is reduced.

[0026] The invention of technical solution 5 is based on the invention of technical solution 1 or technical solution 2, wherein the outer side of the vehicle's outer sidewall makes surface contact with the vehicle door frame.

[0027] In the present invention, as described in technical solution 5, the outer sidewall of the vehicle makes surface contact with the door frame. Therefore, the outer sidewall is held between the door frame and the door glass, which increases its rigidity. As a result, the vibration energy transmitted to the thick-walled portion can be effectively attenuated, reducing noise caused by wind noise.

[0028] The effects of the invention

[0029] A thick-walled portion is formed on the inner side of the outer sidewall of the glass slide channel, protruding inward and sliding in contact with the door glass. Therefore, compared with the sealing lip in the prior art, the rigidity of the glass slide channel is increased, and the vibration energy of the door glass can be effectively dissipated when it slides in contact with the door glass. As a result, noise caused by wind noise can be reduced.

[0030] Furthermore, the stiffness of the thick-walled section is higher than that of the main body of the outer sidewall of the vehicle, thus further increasing the rigidity of the glass slide. As a result, the vibration energy of the door glass can be more effectively directed and dissipated towards the thick-walled section of the glass slide, reducing noise caused by wind noise.

[0038] Figure 8 This is a cross-sectional view showing the current installation structure of the glass slide, and it is in contrast to... Figure 1 The cross-sectional view corresponding to the XX line (Patent Document 2). Detailed Implementation

[0039] based on Figures 1 to 5 The first embodiment of the present invention will be described. Figure 1 This is a front view of the left front door 1 of a car, viewed from the outside. A door frame 3 is mounted on the upper part of the door body 2 that constitutes the front door 1. A window opening is formed by the door frame 3 and the upper edge of the door body 2. A glass slide 10 is installed on the inner periphery of the window opening and inside the door body 2 to guide the raising and lowering of the door glass 4. Furthermore, this invention can be applied not only to the left front door 1, but also to the right front door and the left and right rear doors. Additionally, it can be applied to sliding doors with raised and lowered windows.

[0040] Figure 2 This is a simplified front view of the glass slide 10 as seen from the outside of the vehicle. The glass slide 10 is composed of the following components: a first extrusion molding section 11, corresponding to the horizontal frame of the door frame 3; a second extrusion molding section 12, corresponding to the vertical frame of the front side of the front door 1; and a third extrusion molding section 13, corresponding to the vertical frame of the rear side. The front end of the first extrusion molding section 11 is connected to the upper end of the second extrusion molding section 12 by a first die molding section 14. Furthermore, the rear end of the first extrusion molding section 11 is connected to the upper end of the third extrusion molding section 13 by a second die molding section 15.

[0041] Figure 3 Is with Figure 1 The cross-sectional view corresponding to line XX. The glass slide 10 is formed in a tunnel shape (the cross-section is approximately "コ"-shaped) with the bottom wall 20, the outer side wall 30, and the inner side wall 40 as the basic framework. The bottom wall 20 is connected to the outer side wall 30 and the inner side wall 40 by grooves 21 on the outer and inner sides of the vehicle in a manner that allows it to unfold freely. In addition, the inner side wall 40 is formed to be larger than the outer side wall 30, and its shape is formed to be asymmetrical with the inner side being larger.

[0042] The bottom wall 20 is formed in an approximately plate-like shape, and a plurality of bottom wall recesses 22 are formed continuously and parallelly in the longitudinal direction on the inner surface of the bottom wall 20 (on the side of the door glass 4). In addition, a bottom wall sealing lip 23 is formed on the outer surface of the bottom wall 20, and the bottom wall sealing lip 23 abuts against the tunnel-shaped (cross-section approximately "ko") door frame groove 5 formed in the door frame 3, sealing the bottom wall 20 and the door frame groove 5.

[0043] On the outer side of the vehicle outer sidewall 30, near the connection with the bottom wall 20 and in the direction of the front end of the vehicle outer sidewall 30, a first vehicle outer retaining lip 33 and a second vehicle outer retaining lip 34 are formed that engage with the door frame groove 5. The door frame groove 5, which is formed in a curved manner, is retained by the first vehicle outer retaining lip 33 and the second vehicle outer retaining lip 34.

[0044] A thick-walled portion 31 is formed on the inner side of the outer sidewall 30 of the vehicle. This thick-walled portion 31 protrudes inward and slides in contact with the door glass 4, and its hardness is higher than that of the main body portion 37 of the outer sidewall 30. Furthermore, in Figure 3 In this design, the outer sidewall body 37 of the outer sidewall 30, which forms the thick-walled portion 31, is also formed to be relatively thick. However, the thickness of the outer sidewall body 37 is the same as in the prior art, allowing the thick-walled portion 31 to be formed thicker to the sliding contact position with the door glass 4. This allows the door glass 4 to slide into contact with the thick-walled portion 31 formed on the outer sidewall 30, making the hardness of the thick-walled portion 31 higher than that of the outer sidewall body 37. This reduces the rigidity difference between the door glass 4 and the outer sidewall 30, enabling the vibration energy of the door glass 4 to flow (transmit) and dissipate towards the thick-walled portion 31 effectively through impedance matching. As a result, noise caused by wind noise can be reduced.

[0045] Multiple convex ribs 32 are formed continuously and parallel along the length of the inner surface of the thick-walled portion 31. The ribs 32 prevent dust, dirt, foreign objects, etc. from getting stuck in the thick-walled portion 31 and causing abnormal noises when the door glass 4 is raised or lowered.

[0046] A cover lip 36 is formed on the front end 39 of the outer sidewall 30, on the side opposite to the bottom wall 20 in the direction of the door glass 4. The cover lip 36 abuts against the outer side surface of the door glass 4, which can prevent rainwater and dust from entering the thick wall portion 31 and prevent the thick wall portion 31 from deteriorating. In addition, it can improve the sealing performance relative to the door glass 4.

[0047] A locking portion 35 is formed at the base of the cover lip 36 facing outwards, which can fix the end of the pillar trim 6 and seal the gap between the pillar trim 6 and the surface of the door glass 4.

[0048] The outer sidewall 30 of the vehicle makes surface contact with the door frame groove 5. Therefore, by clamping the outer sidewall 30 between the door glass 4 and the door frame 3, the rigidity of the outer sidewall 30 is increased. As a result, the vibration energy of the door glass 4 can be effectively transmitted to the outer sidewall 30 through impedance matching, and the outer sidewall 30, i.e., the glass groove 10, can dissipate with a high degree of attenuation.

[0049] An inner sealing lip 41 is formed on the outer side of the inner sidewall 40. This inner sealing lip 41 extends outward from between the front end 47 of the inner sidewall and the bottom wall 20, and towards the outer side of the vehicle and towards the bottom wall 20. The outer side of the vehicle slides in contact with the door glass 4. Regarding the inner sealing lip 41, when the door glass 4 slides in contact with the thick wall portion 31 of the outer sidewall 30 and the inner sealing lip 41, the reaction forces from the outer and inner sides of the vehicle are greater on the inner side than on the outer side. This increases the pressing pressure towards the thick wall portion 31 of the door glass 4, which is consistent with the current... Figure 7 In comparison, it is shorter in length and thicker in thickness.

[0050] Furthermore, the increase in rigidity of the glass slide 10 is most incompatible with the sliding performance related to glass lifting and lowering. That is, if the reaction force from the inner sealing lip 41 on the door glass 4 is too large, it will adversely affect the lifting and lowering of the door glass 4, i.e., its sliding performance. On the other hand, if the reaction force from the inner sealing lip 41 on the door glass 4 is reduced, there is no problem with sliding performance, but the pressing force towards the thick-walled portion 31 is reduced, and the rigidity of the thick-walled portion 31 is reduced. Therefore, in this embodiment, the length and thickness of the inner sealing lip 41 are adjusted considering both sliding performance and rigidity. Sliding performance and rigidity will be described in detail later.

[0051] On the outer side of the inner sidewall 40 of the vehicle, and further from the bottom wall 20 than the inner sealing lip 41, a secondary lip 42 is formed in the opposite direction to the inner sealing lip 41. The front end of the secondary lip 42 abuts against the inner side of the inner sealing lip 41, assisting the inner sealing lip 41 in pressing the inner side of the door glass 4 towards the outer side of the vehicle.

[0052] On the inner side of the inner sidewall 40, a first inner side retaining lip 43 and a second inner side retaining lip 44 are formed, which engage with the curved portion of the door frame groove 5, which has a curved portion near the connection with the bottom wall 20 and in the direction of the front end of the inner sidewall 40. Furthermore, an abutting lip 45 is formed between the first inner side retaining lip 43 and the second inner side retaining lip 44. The inner sidewall 40 is held in the curved door frame groove 5 by the first inner side retaining lip 43, the second inner side retaining lip 44, and the abutting lip 45.

[0053] A cover lip 46 is formed at the front end 47 of the inner side wall 40 facing the inner side of the vehicle. The cover lip 46 abuts against the door frame groove 5, which can prevent the intrusion of rainwater, dust and noise and improve the sealing performance relative to the door frame groove 5.

[0054] In this embodiment, the glass slide 10, except for the thick-walled portion 31, uses an olefin thermoplastic elastomer (TPO) with an IRHD (International Rubber Hardness) of 80±5, and the thick-walled portion 31 uses a TPO with an IRHD of 100±5, and is manufactured by extrusion molding.

[0055] Furthermore, in embodiments of the present invention, the material constituting the glass slide 10 can be formed from rubber, thermoplastic elastomers, soft synthetic resins, etc. In the case of rubber, regarding EPDM (ethylene propylene diene monomer rubber), as a thermoplastic elastomer, from the viewpoints of weather resistance, reusability, and cost, olefin-based thermoplastic elastomers (TPO) and dynamically crosslinked thermoplastic elastomers (TPV) are preferred.

[0056] Figure 4 Is Figure 3 glass slide and Figure 7 The graph shown is a result of measuring the position of the door glass when it is displaced inwards or outwards within the glass slide, as well as the reaction force from the glass slide. Figure 3 The reaction forces of the thick-walled portion 31 and the inner sealing lip 41 were measured in the glass groove. Figure 7 The reaction forces of the outer sealing lip 330 and the inner first sealing lip 410 were measured. Figure 4 In the diagram, the solid line 'a' represents the invention (…). Figure 3 The reaction force from the outside of the vehicle, represented by the dashed line b, indicates the invention ( Figure 3 The reaction force from inside the vehicle. Additionally, the dotted line 'c' indicates existing technology (…). Figure 7 The reaction force from the outside of the vehicle, represented by the double-dotted line d, indicates the prior art. Figure 7 The reaction force from inside the car.

[0057] exist Figure 4 In the middle, rigidity can be verified by the slope at the point (●) where the reaction forces on the outer and inner sides of the vehicle intersect at the equilibrium position, and sliding performance can be verified by the magnitude.

[0058] according to Figure 4 It is clearly understood that the slope of the reaction force 'a' on the outer side of the vehicle is steeper than that of the reaction force 'c' in the prior art, thus significantly increasing rigidity. On the other hand, the magnitude of the reaction force at the equilibrium position (●) between the outer and inner sides of the vehicle is slightly larger than that in the prior art. Therefore, it can be seen that the present invention simultaneously satisfies the contradictory requirements of increased rigidity and good sliding performance.

[0059] Figure 5 Yes Figure 3 glass slide and Figure 7 The graph shown compares the relationship between the current glass slide's position relative to the seat's ear, the frequency at the center of the outer side of the door glass, and the sound sensitivity. According to... Figure 5 It is clear that, especially in the high-frequency range of 3kHz or higher, the vibration of the car door glass is significantly reduced, i.e., the noise is reduced.

[0060] As described above, the present invention focuses on impedance matching relative to the door glass and relates to a glass slide. By forming a thick wall portion with a hardness higher than that of the main body of the outer sidewall of the vehicle and making it slide in contact with the door glass, the rigidity of the glass slide can be increased. In particular, by setting the reaction force against the door glass to be greater on the inner side of the vehicle than on the outer side, the sliding performance of the door glass will not be affected, and the vibration of the door glass can be significantly reduced, thus reducing noise.

[0061] Furthermore, the present invention does not require any change to the material of the glass track, and will not affect other performance aspects of the glass track (e.g., the sealing performance between the glass and the door frame related to installation into the door frame, prevention of raindrops, dust, and other intrusions).

[0062] Figure 6 This is the glass slide of the second embodiment of the present invention, and it is related to... Figure 1 The cross-sectional view corresponding to the YY line. The difference between this second embodiment and the first embodiment described above is that, in this second embodiment, an outer sealing lip 38 is formed on the outer sidewall 30 of the vehicle. The outer sealing lip 38 extends from the front end 39 of the outer sidewall towards the inner side of the vehicle and towards the bottom wall 20. The inner side of the vehicle slides in contact with the door glass 4 and does not abut against the thick wall portion 31.

[0063] By forming an outer sealing lip 38 that allows the inner side of the vehicle to slide in contact with the door glass 4, the sealing performance relative to the door glass 4 can be improved, and the intrusion of raindrops, dust, etc. can be prevented, and the glass track can be made to pass through the track ( Figure 7 The noise reduction of arrow A).

[0064] Furthermore, since the outer sealing lip 38 does not abut against the thick-walled portion 31, similar to the first embodiment described above, the vibration energy of the door glass 4 can be effectively dissipated at the thick-walled portion 31 when it slides into contact with the door glass 4. As a result, noise caused by wind noise can be reduced.

[0065] In addition to the claims, the present invention includes the following points.

[0066] According to the glass sliding groove described in technical solution 3, an outer sealing lip is formed on the outer sidewall of the vehicle. The outer sealing lip extends from the front end of the outer sidewall or from the inner side of the outer sidewall between the front end of the outer sidewall and the bottom wall towards the inner side of the vehicle and towards the bottom wall. The inner side of the lip slides in contact with the door glass.

[0067] The outer sealing lip of the vehicle does not abut against the thick-walled portion.

[0068] According to the glass groove described in technical solution 4, the outer side of the vehicle's outer sidewall makes surface contact with the groove of the vehicle door frame.

[0069] When implementing this invention, it is not limited to the above-described embodiments. Various modifications can be made as long as they do not depart from the purpose of this invention.

[0070] For example, in the above embodiment, it is installed in the XX section. Figure 3 The glass slide groove of the structure was installed in the YY section. Figure 6 Glass tracks can be installed, but they can also be installed in the opposite direction. In addition, any glass track can be installed on two sections.

[0071] For example, the glass groove of the second embodiment described above can be applied to... Figure 2 The first extrusion molding section.

[0072] For example, in the two embodiments described above, as prior art, as Figure 7 The improvement example was explained, but it can also be applied to other situations. Figure 8 The existing technology of vehicle outer sidewall.
