Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile accessories, in particular to a triangular window rubber wrapping structure for weakening wind noise and a vehicle. BACKGROUND

[0002] In the early years, due to the less fierce competition in the automobile market, customers had low requirements on the vehicle NVH (Noise Vibration Harshness) performance. In view of the fact that users are more and more picky, it is necessary to improve the vehicle NVH performance, and thus the noise, vibration and comfort of the vehicle are optimized.

[0003] In some related technologies, the commercial MPV market is increasingly hot, becoming a field that major manufacturers are competing to occupy. Due to the longer wheelbase, the front end of the vehicle body is generally designed with a fixed front triangular window to increase the side view of the front row. However, this will cause the following problems:

[0004] As shown in Figure 1 and Figure 2 , the split seam position of the front door will produce a gap H between the door panel 7 and the corner window glass 6. This gap is basically above the outside rearview mirror and belongs to an area with relatively large wind noise. If the split seam position is not properly handled, the vehicle will produce obvious wind noise during high-speed driving, affecting the driving quality. In addition, in order to ensure that the door panel 7 can be normally opened and not collide with the corner window glass 6, the gap is inevitable. Moreover, considering the manufacturing tolerance, the gap needs to be appropriately larger, so the wind noise is larger. SUMMARY

[0005] The embodiments of the present application provide a triangular window rubber wrapping structure for weakening wind noise and a vehicle, so as to solve the problem that in the related art, the split seam position of the front door produces a gap between the door panel and the corner window glass, resulting in large wind noise and affecting the vehicle NVH performance.

[0006] In a first aspect, a triangular window rubber wrapping structure for weakening wind noise is provided, which comprises:

[0007] A corner window glass connecting portion, which is provided with a sealing connecting groove, an inner wall surface of the sealing connecting groove is used for sealing connection with an edge of the corner window glass, and the corner window glass is sealingly connected to two surfaces inside and outside the vehicle;

[0008] A sealing lip is connected to the corner window glass connecting part at a root end away from one end of the sealing connecting groove, and the root end is substantially parallel to the sealing connecting groove; a lip of the sealing lip is connected to the root end, and the lip extends from the root end to the outside of the vehicle and is used to abut against the abutment position of the surface of the door panel on the inside of the vehicle. Thus, the gap between the door panel and the corner window glass is completely sealed after the door is closed, the airflow circulation is blocked, the wind noise during vehicle driving is weakened, and the vehicle NVH quality is improved; and the normal opening of the door panel is not affected.

[0009] In some embodiments, the lip extends in a designed arc shape, and the concave direction of the designed arc shape is towards the inside of the vehicle. Such a design makes the lip have a stress dispersion function compared to a straight line structure, so that the pressure generated when the lip abuts against the surface of the door panel on the inside of the vehicle is evenly dispersed, and the service life of the lip is improved.

[0010] In some embodiments, the distance between the abutment position and the edge of the door panel is greater than 1-3 mm, and the abutment position is the position where the lip abuts against the surface of the door panel on the inside of the vehicle when the door is closed.

[0011] In some embodiments, the outer surface of the lip near one end of the door panel is provided with a lubricating coating; the possibility of friction noise is eliminated, and the friction consumption during use is also reduced, prolonging the service life.

[0012] In some embodiments, the root end on the inside of the vehicle is provided with a weakening groove; the rigidity of the lip is reduced, so that the root end is more easily deformed under pressure after the door is closed, and the lip is more easily abutted against the door panel.

[0013] In some embodiments, the weakening groove is a circular groove, and the diameter of the circular groove is 0.2-0.4 mm.

[0014] In some embodiments, the corner window glass connecting part on the inside of the vehicle is a plane;

[0015] The wall thickness of the corner window glass connecting part on the outside of the vehicle gradually decreases from the end near the door panel to the end of the corner window glass to form a noise reduction inclined surface; the arrangement of the noise reduction inclined surface is beneficial for airflow guidance, thereby reducing noise.

[0016] In some embodiments, the corner window glass connecting part on the outside of the vehicle is provided with a circular arc transition part for connecting the corner window glass on the outside of the vehicle.

[0017] In some embodiments, the corner window glass connecting part is provided with a support diffusion part for contacting the vehicle body, the support diffusion part extends towards the interior of the vehicle, and forms an acute angle with the root of the sealing lip. The setting of the support diffusion part makes the part of the sealing lip under pressure after the door is closed can be transmitted to the support diffusion part from the root, and also makes the corner window glass connecting part not deformed during use, to avoid the risk of the sealing connecting groove and the corner window glass being separated.

[0018] In a second aspect, a vehicle is provided, comprising: a triangular window encapsulation structure for weakening wind noise.

[0019] The beneficial effects brought by the technical solutions provided in the application include:

[0020] The embodiments of the application provide a triangular window encapsulation structure for weakening wind noise and a vehicle. The inner wall surface of the sealing connecting groove of the corner window glass connecting part is used for sealing connection with the edge of the corner window glass and the two surfaces of the corner window glass located inside and outside the vehicle.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0028] The commercial MPV market is increasingly hot, becoming the field that major manufacturers compete to occupy. The MPV model generally designs a fixed front triangular window at the front end of the vehicle body due to the longer wheelbase, increasing the front row side view. However, the following problems will be caused:

[0029] As shown in Figure 1 and Figure 2 , a gap H between the door sheet metal 7 and the corner window glass 6 will be generated at the split seam position of the front door. This gap is basically above the outside rearview mirror and belongs to an area with relatively large wind noise contribution. If the split seam position is not properly handled, obvious wind noise will be generated during high-speed driving of the vehicle, affecting the driving quality. In addition, in order to ensure that the door sheet metal 7 normally opens and does not collide with the corner window glass 6, the gap is inevitably present. Moreover, considering the manufacturing tolerance, the gap needs to be appropriately larger, so that the wind noise is larger.

[0030] Therefore, the embodiments of the present application provide a triangular window encapsulation structure for weakening wind noise and a vehicle, to solve the problem that in the related art, a gap between the door sheet metal and the corner window glass is large at the split seam position of the front door, resulting in large wind noise and affecting the NVH performance of the vehicle.

[0031] Please refer to Figures 3-4 , a triangular window encapsulation structure for weakening wind noise, comprising: a corner window glass connecting part 1 and a sealing lip 3;

[0032] The corner window glass connecting part 1 is provided with a sealing connecting groove 2, and the inner wall surface of the sealing connecting groove 2 is used for sealing connection with the edge of the corner window glass 6 and the two surfaces of the corner window glass 6 located inside and outside the vehicle;

[0033] The root of the sealing lip 3 is connected to one end of the corner window glass connecting part 1 away from the sealing connecting groove 2, and the root is substantially parallel to the sealing connecting groove 2. The lip of the sealing lip 3 is connected to the root, the lip extends from the root to the vehicle outward direction, and is used for abutting against the abutting position of the surface of the vehicle door sheet metal 7 located on the inside of the vehicle, that is, is provided with interference.

[0034] Wherein the inside of the vehicle refers to the side of the door panel 7 and the quarter window glass 6 located in the inside of the vehicle when the door is closed, wherein the quarter window rubber structure is made of rubber material and is formed into a whole with the quarter window glass 6 by injection molding.

[0035] Thus, through the above structure, the gap between the door panel and the quarter window glass is completely sealed after the door is closed, the airflow circulation is blocked, the wind noise during vehicle driving is weakened, and the vehicle NVH quality is improved; and the normal opening of the door panel 7 is not affected.

[0036] In some preferred embodiments, the lip of the sealing lip 3 extends in a designed arc shape, and the concave direction of the designed arc shape is towards the inside of the vehicle. Such a design makes the lip have the effect of dispersing the stress area compared to a straight line structure, so that the pressure generated when the lip and the surface of the door panel 7 on the inside of the vehicle abut is evenly dispersed, improving the service life of the lip.

[0037] Further, the distance between the abutting position and the edge of the door panel 7 is greater than 1-3 mm, and the abutting position is the position where the lip abuts on the surface of the door panel 7 on the inside of the vehicle when the door is closed. In this way, the lip and the edge of the door panel 7 are only slightly in contact, and during high-speed driving of the vehicle, external airflow breaks through the lip and the door panel 7 and enters the fitting gap H.

[0038] Further, the outer surface of the end of the lip close to the door panel 7 is provided with a lubricating coating to eliminate the possibility of friction noise and reduce friction consumption during use, prolonging the service life.

[0039] In some preferred embodiments, the root on the inside of the vehicle is provided with a weakening groove 4 to reduce the rigidity of the lip, so that the root is more easily deformed under pressure after the door is closed, and the lip is more easily abutted with the door panel 7. The weakening groove 4 is a circular groove with a diameter of 0.2-0.4 mm.

[0040] In some preferred embodiments, the inside of the quarter window glass connecting part 1 on the inside of the vehicle is a plane b; the wall thickness of the outside of the quarter window glass connecting part 1 gradually decreases from the end close to the door panel 7 to the end of the quarter window glass 6 to form a noise reduction inclined surface a; the setting of the noise reduction inclined surface a is conducive to airflow guidance, thereby reducing noise. The inclined direction of the noise reduction inclined surface a is inclined from the quarter window to the door panel 7 towards the outside of the vehicle, which is conducive to airflow circulation. The inclined angle of the noise reduction inclined surface a can be selected and set according to specific conditions.

[0041] Further, the corner window glass connecting part 1 is provided with a circular arc transition part on the side outside the vehicle, which is used to connect with the corner window glass 6 on the side outside the vehicle. Such a design is also beneficial for airflow guiding, thereby reducing the generation of noise, i.e. reducing the friction with airflow, and the wind noise generated is smaller compared with the original direct edge.

[0042] In some preferred embodiments, the corner window glass connecting part 1 is provided with a support diffusion part 5 for contacting the vehicle body, which extends towards the inside of the vehicle and forms an acute angle with the root of the sealing lip 3.

[0043] The support diffusion part 5 is provided so that, after the door is closed, part of the force of the sealing lip 3 after being pressed can be transmitted from the root thereof to the support diffusion part 5, and also so that the corner window glass connecting part 1 does not deform during use, thereby avoiding the risk of the sealing connection groove 2 and the corner window glass 6 being separated.

[0044] The application also provides a vehicle comprising the above-mentioned weak wind noise triangular window encapsulation structure. The corner window glass connecting part 1 of the triangular window encapsulation structure is provided with a sealing connection groove 2, the inner wall surface of the sealing connection groove 2 is used to seal and connect with the edge of the corner window glass 6 and the two surfaces of the corner window glass 6 on the inside and outside of the vehicle; the root of the sealing lip 3 is connected to one end of the corner window glass connecting part 1 away from the sealing connection groove 2, and the root is substantially parallel to the sealing connection groove 2; the lip part of the sealing lip 3 is connected to the root, the lip part extends from the root towards the outside of the vehicle, and is used to abut against the surface of the door panel 7 on the inside of the vehicle, i.e. is provided with an interference.

[0045] The inside of the vehicle refers to the side of the door panel 7 and the corner window glass 6 in the inside space of the vehicle when the door is closed, wherein the triangular window encapsulation structure is made of rubber material and is formed as a whole with the corner window glass 6 by injection molding.

[0046] Therefore, through the above structure, the gap between the door panel and the corner window glass is completely blocked after the door is closed, the circulation of airflow is blocked, thereby weakening the wind noise during vehicle driving and improving the NVH quality of the vehicle; and the normal opening of the door panel 7 is not affected.

[0047] In some preferred embodiments, the weak wind noise triangular window encapsulation structure is measured, and the specific conditions are as shown in Figure 4 The curve e in the figure represents the wind noise curve of the corner window without sealing design at a vehicle speed of 120 km.

[0048] The curve f represents the wind noise curve of the corner window with sealing design (encapsulation without wedge-shaped guide) at a vehicle speed of 120 km.

[0049] Curve g represents the wind noise curve at a speed of 120km / h for the corner window with the sealing design (rubber wedge guide).

[0050] NVH generally focuses on the sound quality of the medium frequency band above 30DB and in the frequency range of 200-8000HZ, because the frequency is too low to be heard by the ear, and the proportion of the frequency is too high to be ignored; From the three curves above 30DB and in the frequency range of 200-8000HZ, it can be seen that the structure of the application effectively reduces wind noise and improves the quality of vehicle NVH, and does not affect the normal opening of the door panel 7.

[0051] The principle of the application is:

[0052] (1) The root of the sealing lip 3 is connected to the corner window glass connecting part 1 away from one end of the sealing connecting groove 2, and the root is substantially parallel to the sealing connecting groove 2; The lip of the sealing lip 3 is connected to the root, the lip extends from the root to the outside of the vehicle, and is used to abut the surface of the door panel 7 on the inside of the vehicle, that is, the interference is set. The inside refers to the side of the door panel 7 and the corner window glass 6 in the inside space when the door is closed, and the triangular window rubber structure is made of rubber material and is made into a whole with the corner window glass 6 by injection molding. Thus, the gap between the door panel and the corner window glass is completely sealed after the door is closed, the airflow is blocked, the wind noise during vehicle driving is weakened, and the quality of vehicle NVH is improved; and the normal opening of the door panel 7 is not affected.

[0053] (2) The lip of the sealing lip 3 extends according to the designed arc shape, and the concave direction of the designed arc shape faces the inside of the vehicle. Such a setting makes the lip have the function of dispersing the stress surface compared with the straight line structure, so that the pressure generated when the lip abuts the surface on the inside of the door panel 7 is evenly dispersed, and the service life of the lip is improved.

[0054] (3) The distance between the abutting position and the edge of the door panel 7 is greater than 1-3mm, and the abutting position is the position of the lip abutting on the surface on the inside of the door panel 7 when the door is closed. In this way, the lip and the edge of the door panel 7 only have slight contact, and in the process of high-speed driving of the vehicle, external airflow breaks through the lip and the door panel 7 and enters the fitting gap H. The root on the inside is provided with a weakening groove 4 to reduce the rigidity of the lip, so that the root is more easily deformed under pressure after the door is closed, and the lip is more easily abutted with the door panel 7.
