Description
Technical Field
[0001] The utility model relates to the field of automobiles, in particular to a corner window structure of a frameless door, a door and a vehicle. Background Art
[0002] With the improvement of people's living standards, cars have been widely used as a daily means of transportation in life. Generally, car doors are divided into two types: framed doors and frameless doors. Framed doors have a frame on the top of the door, and a seal is installed on the frame. The frame can also play a guiding or stabilizing role in the process of the car glass rising. The door glass can be sealed with the sealing strip on the frame, and after the door is closed, it can be sealed with the sealing strip on the door frame. Frameless doors have no frame on the top, so from the overall appearance, they will appear more simple and generous, and are gradually becoming the favorite of more and more people.
[0003] Frameless car doors usually have triangular windows and liftable door glass. The lack of frame limiters or fixations between the triangular windows and the door glass of frameless car doors and the complex structure make water leakage of frameless car doors a difficult problem in the industry. Utility Model Content
[0004] In view of this, it is necessary to address the above problems. The utility model provides a corner window structure of a frameless door, a door and a vehicle to reduce the water leakage problem of the frameless door.
[0005] The utility model first provides a corner window structure for a frameless vehicle door, wherein the frameless vehicle door comprises a vehicle door sheet metal and a vehicle door glass, including: a corner window glass; a guide rail for being installed on the vehicle door sheet metal, wherein the guide rail extends along the Z-axis direction; and a rubber-coated structure, which is arranged on the guide rail, wherein the rubber-coated structure comprises a first supporting section, a second supporting section and a connecting section connecting the first supporting section and the second supporting section, wherein the first supporting section and the second supporting section are respectively located on both sides of the guide rail, and the connecting section is located at the top end of the guide rail, wherein the first supporting section wraps around the outer edge of the corner window glass, and the second supporting section and the connecting section are provided with guide grooves for sliding connection with the vehicle door glass, and the connecting section is also provided with a water diversion groove connected with the guide groove.
[0006] In the corner window structure provided by the utility model, the first supporting section is used for sealingly connecting the corner window glass and the guide rail, and when the vehicle door glass rises to the guide groove along the Z-axis direction, the second supporting section can seal the vehicle door glass and the guide rail; because when the vehicle door glass rises to the topmost point along the Z-axis direction, the top edge of the vehicle door glass is basically flush with the top edge of the corner window glass, and the top edge of the vehicle door glass is inclined toward the corner window glass, so the rainwater remaining on the top edge of the vehicle door glass will flow toward the corner window glass, and when the rainwater flows from the vehicle door glass to the connecting section, it will flow into the water guide groove, thereby preventing the rainwater remaining on the top edge of the vehicle door glass from flowing to the corner window glass, avoiding water leakage due to excessive rainwater at the corner window glass, thereby reducing the water leakage problem of the vehicle door.
[0007] In one of the embodiments, when the door glass rises to the top of the rubber-coated structure along the guide groove, along the X-axis direction, the distance between the end of the water guide groove away from the door glass and the edge of the door glass is L, and L≥3mm.
[0008] Such an arrangement can avoid the siphon effect of bubbles or water droplets between the inner wall of the water channel and the edge of the door glass, which may cause rainwater flowing down from the top edge of the door glass to be unable to flow into the water channel normally, thereby ensuring that the water channel can drain water normally.
[0009] In one of the embodiments, it further includes a first fixing component and a second fixing component, wherein the first fixing component and the second fixing component are arranged at intervals along the Z-axis direction and are used to fix the guide rail to the door sheet metal.
[0010] Such an arrangement can accurately position the guide rail in the X-axis and Z-axis directions, reduce assembly errors, and thus reduce water leakage problems at the corner window glass.
[0011] In one embodiment, the first fixing assembly includes a first fixing member and a first fastener, the first fixing member is arranged on the guide rail, and the first fixing member has a first through hole in the Y-axis direction, and the first fastener passes through the first through hole and is fixed to the door sheet metal.
[0012] With such arrangement, the structure of the first fixing assembly is simple, so as to facilitate installation of the guide rail on the door sheet metal.
[0013] In one embodiment, the second fixing assembly includes a second fixing member and a second fastener, the second fixing member is arranged on the guide rail, and the second fixing member has a second through hole in the Y-axis direction, and the second fastener passes through the second through hole and is fixed to the door sheet metal.
[0014] With such arrangement, the structure of the second fixing assembly is simple, so that the guide rail can be easily installed on the door sheet metal.
[0015] In one embodiment, the first supporting section includes a first sub-section and a second sub-section, the first sub-section extends along the Z-axis direction, the second sub-section extends along the X-axis direction, and the edges of the corner window glass are fixedly connected to the first sub-section and the second sub-section respectively; the corner window structure also includes a third fixing member arranged on the second sub-section, and the third fixing member is used to fix the second sub-section and the door sheet metal.
[0016] In this arrangement, the third fixing part can prevent the guide rail from rotating around the Z axis relative to the door sheet metal, thereby ensuring that the dimensions of the corner window glass and the door sheet metal in the Y axis direction match, and realizing adaptive compensation for the assembly dimension error in the Y axis direction caused by dimensional accuracy between the corner window glass and the door sheet metal, thereby reducing the problem of water leakage at the corner window glass.
[0017] The utility model also provides a vehicle door, comprising a vehicle door sheet metal, a vehicle door glass and the above-mentioned corner window structure, wherein the guide rail is mounted on the vehicle door sheet metal, the vehicle door glass is liftably mounted on the vehicle door sheet metal, and the vehicle door glass is slidably connected to the guide rail.
[0018] The utility model also provides a vehicle, comprising a door frame structure and the vehicle door described above, wherein the vehicle door is rotatably connected to the door frame structure; the door frame structure comprises a side panel upper sealing strip, and when the vehicle door is in a closed state, there is a gap between the inner lip edge of the connecting section and the side panel upper sealing strip.
[0019] Furthermore, a gap T between the inner lip edge of the connecting section and the sealing strip on the side enclosure is not less than 0.5 mm.
[0020] Such an arrangement can avoid interference and distortion between the inner lip edge of the connecting section and the sealing strip on the side panel due to dimensional accuracy and assembly errors, thereby reducing water leakage problems at the corner window structure.
[0021] In one embodiment, the door frame structure also includes a door opening sealing strip, which includes an assembly part and a sealing part. A deformation cavity is provided between the assembly part and the sealing part, and foam is provided in the deformation cavity. The foam has a hollow structure, and the outer diameter of the foam is 10 mm, and the wall thickness of the foam is 1.5 mm.
[0022] With such a configuration, the foam can appropriately reduce the deformation capacity of the sealing part, ensuring that the sealing part can fit tightly against the inner side of the door glass, thereby reducing water leakage at the door frame structure and extending the service life of the door opening sealing strip; moreover, the foam also has good sound insulation performance, effectively reducing wind noise at the door frame structure.

DETAILED DESCRIPTION
[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.
[0035] With the improvement of people's living standards, cars have been widely used as a daily means of transportation in life. Generally, car doors are divided into two types: framed doors and frameless doors. Framed doors have a frame on the top of the door, and a seal is installed on the frame. The frame can also play a guiding or stabilizing role in the process of the car glass rising. The door glass can be sealed with the sealing strip on the frame, and after the door is closed, it can be sealed with the sealing strip on the door frame. Frameless doors have no frame on the top, so from the overall appearance, they will appear more simple and generous, and are gradually becoming the favorite of more and more people.
[0036] Frameless car doors usually have triangular windows and liftable door glass. The lack of frame limiters or fixations between the triangular windows and the door glass of frameless car doors and the complex structure make water leakage of frameless car doors a difficult problem in the industry.
[0037] In order to meet the above requirements, the present application provides a corner window structure for a frameless door, a door and a vehicle to reduce the water leakage problem of the frameless door. For ease of description, the X-axis, Y-axis and Z-axis are defined as the directions of the coordinate axes shown in the figure, and the X-axis is roughly the length direction of the vehicle, the Y-axis is roughly the width direction of the vehicle, that is, the direction perpendicular to the plane where the triangular window and the door glass are located, and the Z-axis is roughly the height direction of the vehicle.
[0038] like Figure 1As shown, the vehicle includes a vehicle body and a vehicle door. The vehicle body is provided with a plurality of door frame structures 400, each door frame structure 400 corresponds to a vehicle door, and each vehicle door is rotatably connected to the door frame structure 400 to realize opening and closing of the door; the door frame structure 400 includes a side upper sealing strip 401. The vehicle door includes a vehicle door sheet metal 200, a vehicle door glass 300 and a corner window structure 100, and the corner window structure 100 includes a corner window glass 10 and a guide rail 20, and the guide rail 20 is installed on the vehicle door sheet metal 200, and the guide rail 20 extends along the Z-axis direction; the vehicle door glass 300 is arranged on the vehicle door sheet metal 200 in a liftable manner, and the vehicle door glass 300 is slidably connected to the guide rail 20 to realize opening and closing of the window. When the vehicle door is in a closed state and the door glass 300 rises to the top along the Z-axis direction, the top edge of the door glass 300 and the top edge of the corner window glass 10 form an approximately continuous transition curve, and both are sealed with the sealing strip 401 on the side panel. The sealing strip 401 on the side panel can ensure the sealing between the vehicle door and the door frame structure 400, and prevent water on the door glass 300 or the corner window glass 10 from entering the interior of the vehicle through the gap between the vehicle door and the door frame structure 400.
[0039] When the door is closed, the door glass 300 will rise and fall along the guide rail 20 and extend through the guide groove of the rubber-encapsulated structure to press against the side upper sealing strip 401 on the door frame structure 400, so that the top edge of the door glass 300 is sealed with the side upper sealing strip 401. However, in actual situations, such as on rainy days or when the vehicle is tested for rain, due to the step difference between the door glass 300 and the corner window glass 10, water leakage is easily caused between the side upper sealing strip 401 and the door glass 300.
[0040] like Figures 2 to 5 As shown, the corner window structure 100 also includes a rubber-coated structure 30, which is arranged on the guide rail 20. The rubber-coated structure 30 includes a first support segment 31, a second support segment 32, and a connecting segment 33 connecting the first support segment 31 and the second support segment 32. The first support segment 31 and the second support segment 32 are respectively located on both sides of the guide rail 20, and the connecting segment 33 is located at the top of the guide rail 20. The first support segment 31 wraps the outer edge of the corner window glass 10, and the second support segment 32 is provided with a guide groove 34 for sliding connection with the door glass 300. The connecting segment 33 is also provided with a water guide groove 331 connected to the guide groove 34.
[0041] When the door glass 300 rises to the top along the Z-axis direction, the top edge of the door glass 300 and the top edge of the corner window glass 10 form a curve that is approximately continuously transitioned. The top edge of the door glass 300 is inclined toward the corner window glass 10, that is, inclined toward the -XZ direction, so the water at the door glass 300 or on the sealing strip 401 on the side wall will flow toward the corner window glass 10, and after flowing from the door glass 300 to the connecting section 33, it will flow into the water guide groove 331, thereby preventing the water at the door glass 300 or on the sealing strip 401 on the side wall from entering the vehicle, and also guiding the water leakage caused by the break between the door glass 300 and the corner window glass 10 into the water guide groove 331, thereby reducing the water leakage problem of the door.
[0042] Furthermore, a drainage channel (not shown) connected to the outside can be provided in the door, and the water diversion groove 331 is connected to the drainage channel to discharge the water flowing into the water diversion groove 331 out of the door. The drainage channel can be set as a conventional structure in the prior art, and the embodiment of the utility model is not specifically limited here.
[0043] When the door glass 300 rises to the top of the rubber-encapsulated structure 30 along the guide groove 34, along the X-axis direction, the distance between the end of the water diversion groove 331 away from the door glass 300 and the edge of the door glass 300 is L, and L≥3mm. Among them, L can be any value greater than or equal to 3mm, such as 3mm, 3.1mm, 3.2mm...3.5mm, 4mm, etc. In this way, it is possible to avoid the generation of bubbles between the inner wall of the water diversion groove 331 and the edge of the door glass 300, which causes the rainwater flowing down from the top edge of the door glass 300 to be unable to flow into the water diversion groove 331 normally, thereby ensuring that the water diversion groove 331 can drain water normally. Preferably, L≥3.5mm, so that the water diversion groove 331 can maintain smooth drainage and faster drainage.
[0044] like Figure 4 As shown, the corner window structure 100 further includes a first fixing assembly 40 and a second fixing assembly 50, which are arranged at intervals along the Z-axis direction and are used to fix the guide rail 20 to the door sheet metal 200. The guide rail 20 is fixed to the door sheet metal 200 by the first fixing assembly 40 and the second fixing assembly 50, and the guide rail 20 can be accurately positioned in the X-axis and Z-axis directions to reduce assembly errors, thereby accurately positioning the entire corner window structure 100, avoiding a gap between the top edge of the corner window glass 10 and the side panel upper sealing strip 401 in the Z-axis direction when the door is in a closed state, and also avoiding the corner window structure 100 from rotating around the axis of the first fixing assembly 40 or the second fixing assembly 50, thereby ensuring the sealing effect between the corner window glass 10 and the side panel upper sealing strip 401, and reducing the water leakage problem at the corner window glass 10.
[0045] Specifically, the first fixing assembly 40 includes a first fixing member 41 and a first fastener (not shown in the figure), the first fixing member 41 is arranged on the guide rail 20, and the first fixing member 41 has a first through hole 411 in the Y-axis direction, and the first fastener passes through the first through hole 411 to be fixed to the door sheet metal 200. The second fixing assembly 50 includes a second fixing member 51 and a second fastener (not shown in the figure), the second fixing member 51 is arranged on the guide rail 20, and the second fixing member 51 has a second through hole 511 in the Y-axis direction, and the second fastener passes through the second through hole 511 to be fixed to the door sheet metal 200. The first fixing assembly 40 and the second fixing assembly 50 have simple structures, so as to facilitate the installation of the guide rail 20 on the door sheet metal 200. In addition, a first mounting position and a second mounting position corresponding to the first through hole 411 and the second through hole 511 respectively can be set on the door sheet metal 200. The first fastener can align and fix the first through hole 411 of the first fixing member 41 with the first mounting position on the door sheet metal 200, and the second fastener can align and fix the second through hole 511 of the second fixing member 51 with the second mounting position on the door sheet metal 200, so as to accurately and reliably fix the guide rail 20 to the door sheet metal 200.
[0046] In one embodiment, at least one of the first fastener and the second fastener is a self-positioning bolt. During the assembly process, when the self-positioning bolt is screwed into the mounting hole on the door sheet metal 200, the spherical head of the self-positioning bolt will automatically find a position in the mounting hole and form a pre-tightening force between the door sheet metal 200, further reducing the assembly error, ensuring the connection accuracy and stability between the corner window structure 100 and the door sheet metal 200, and at the same time improving the assembly efficiency. Of course, in other embodiments, the first fastener and the second fastener can also be set as ordinary screws, bolts and other fasteners, as long as the stability and reliability of the connection between the corner window structure 100 and the door sheet metal 200 can be ensured, and the embodiment of the utility model is not specifically limited here.
[0047] like Figure 4As shown, the first support section 31 includes a first subsection 311 and a second subsection 312, the first subsection 311 extends along the Z-axis direction, the second subsection 312 extends along the X-axis direction, and the edges of the corner window glass 10 are fixedly connected to the first subsection 311 and the second subsection 312 respectively; the corner window structure 100 also includes a third fixing member 60 disposed on the second subsection 312, and the third fixing member 60 is used to fix the second subsection 312 and the door sheet metal 200. The first subsection 311 and the second subsection 312 are respectively connected to the two sides of the corner window glass 10, which can ensure the position accuracy between the corner window glass 10 and the first support section 31 in the X-axis, Y-axis and Z-axis directions, thereby improving the connection accuracy and stability between the corner window glass 10 and the guide rail 20. The third fixing member 60 can prevent the guide rail 20 from rotating around the Z axis relative to the door sheet metal 200, thereby ensuring that the dimensions of the corner window glass 10 and the door sheet metal 200 in the Y axis direction match, and realizing adaptive compensation for the assembly dimension error in the Y axis direction caused by the dimensional accuracy between the corner window glass 10 and the door sheet metal 200, thereby avoiding the existence of a gap in the Y axis direction between the top edge of the corner window glass 10 and the sealing strip 401 on the side panel when the door is in a closed state, thereby further ensuring the sealing effect between the corner window glass 10 and the sealing strip 401 on the side panel, and reducing the water leakage problem at the corner window glass 10.
[0048] Specifically, the third fixing member 60 may also be provided with a third through hole 61 in the Y-axis direction, and the corner window structure further includes a third fastener (not shown), which passes through the third through hole 61 and is fixed to the door sheet metal 200. In addition, the third fastener may also be provided as a self-locating bolt.
[0049] like Figure 1 As shown, the embodiment of the utility model further provides a vehicle door, comprising a vehicle door sheet metal 200, a vehicle door glass 300 and the above-mentioned corner window structure, wherein a guide rail 20 is mounted on the vehicle door sheet metal 200, and the vehicle door glass 300 is liftably mounted on the vehicle door sheet metal 200, and the vehicle door glass 300 is slidably connected to the guide rail 20. The vehicle door glass 300 is lifted and lowered relative to the vehicle door sheet metal 200 along the guide rail 20 to realize opening and closing of the window.
[0050] like Figure 1 , Figure 6 and Figure 7As shown, the embodiment of the utility model further provides a vehicle, including a door frame structure 400 and the above-mentioned door, the door is rotatably connected to the door frame structure 400 to realize opening and closing of the door. The door frame structure 400 includes a side enclosure upper sealing strip 401, and when the door is in a closed state, there is a gap T between the inner lip edge 332 of the connecting section 33 and the side enclosure upper sealing strip 401. When the door glass 300 rises to the top along the Z-axis direction, the top edge of the door glass 300 will squeeze the side enclosure upper sealing strip 401, causing the side enclosure upper sealing strip 401 to deform, and the deformed side enclosure upper sealing strip 401 can fit and wrap the top edge of the door glass 300 to ensure the sealing between the door glass 300 and the door frame structure 400. The gap between the inner lip edge 332 of the connecting section 33 and the sealing strip 401 on the side panel can prevent the inner lip edge 332 of the connecting section 33 and the sealing strip 401 on the side panel from interfering and twisting due to dimensional accuracy and assembly errors, resulting in water leakage at the corner window structure 100, thereby ensuring the stability of the rubber-coated structure 30 and further reducing the water leakage problem at the corner window structure 100.
[0051] In the illustrated embodiment, the gap T between the inner lip 332 of the connecting section 33 and the upper sealing strip 401 of the side wall is not less than 0.5 mm. In this way, while ensuring that the inner lip 332 of the connecting section 33 and the upper sealing strip 401 of the side wall do not interfere with each other and twist, it is also prevented that the gap T between the inner lip 332 of the connecting section 33 and the upper sealing strip 401 of the side wall is too large to cause water leakage. Of course, in other embodiments, the gap T between the inner lip 332 of the connecting section 33 and the upper sealing strip 401 of the side wall can also be adjusted according to the size of the vehicle, and the embodiment of the utility model does not make any specific restrictions here.
[0052] like Figure 1 and Figure 8 As shown, the door frame structure 400 further includes a door opening sealing strip 402, which includes an assembly portion 4021 and a sealing portion 4022. A deformation cavity 4023 is provided between the assembly portion 4021 and the sealing portion 4022, and a foam 4024 is provided in the deformation cavity 4023. The door opening sealing strip 402 is located on the side of the door glass 300 facing the interior of the vehicle, and the assembly portion 4021 is used for sealing and fixing the door frame body (not shown) of the door frame structure 400. When the door glass 300 rises along the Z-axis direction to contact the door opening sealing strip 402, the inner side of the door glass 300 will squeeze the sealing part 4022 of the door opening sealing strip 402, causing the sealing part 4022 to deform. The deformed sealing part 4022 can be tightly attached to the inner side of the door glass 300 to ensure the sealing between the sealing part 4022 and the door glass 300, thereby preventing rainwater on the top edge of the door glass 300 from flowing into the interior of the vehicle along the inner side of the door glass 300.
[0053] Among them, the deformation cavity 4023 allows the sealing part 4022 to have a larger deformation space, so as to prevent the sealing part 4022 from affecting the normal lifting and lowering of the door glass 300. The foam 4024 can appropriately reduce the deformation capacity of the sealing part 4022, ensuring that the sealing part 4022 can be closely attached to the inner side of the door glass 300, thereby reducing the water leakage problem at the door frame structure 400. At the same time, the foam 4024 can also prevent the elasticity of the sealing part 4022 from gradually weakening due to long-term use, resulting in the inability to effectively rebound to the original shape, thereby extending the service life of the door opening sealing strip 402. In addition, the foam 4024 also has good sound insulation performance, so as to effectively reduce the wind noise at the door frame structure 400.
[0054] like Figure 8 As shown, in the illustrated embodiment, the foam 4024 is a hollow structure, the outer diameter D of the foam 4024 is 10 mm, and the wall thickness H of the foam 4024 is 1.5 mm. The hollow structure allows the foam 4024 to have a larger deformation space, thereby preventing the excessive hardness of the foam 4024 from affecting the normal deformation of the sealing part 4022, thereby preventing the sealing part 4022 from affecting the normal lifting of the door glass 300. In addition, the foam 4024 is adapted to the deformation cavity 4023, so that the foam 4024 can be stably arranged in the deformation cavity 4023. Of course, in other embodiments, when the size of the door opening sealing strip 402 changes, the size of the foam 4024 can also change accordingly, and the embodiment of the utility model is not specifically limited here.
[0055] In the illustrated embodiment, a water guide groove 331 is provided in the connection section 33 of the rubber-encapsulated structure 30 to prevent rainwater remaining on the top edge of the door glass 300 from flowing to the corner window glass 10; the corner window structure 100 is fixedly connected to the door sheet metal 200 through the first fixing assembly 40, the second fixing assembly 50 and the third fixing member 60 to reduce the assembly error of the corner window structure 100; a gap T is provided between the inner lip edge 332 of the connection section 33 and the upper sealing strip 401 of the side wall to prevent the inner lip edge 332 of the connection section 33 and the upper sealing strip 401 of the side wall from interfering and twisting; and a foam 4024 is provided in the deformation cavity 4023 of the door opening sealing strip 402 to ensure the sealing between the sealing part 4022 and the door glass 300. The various parts cooperate with each other, thereby solving the water leakage problem of the frameless door.
[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
