Description

Technical Field

[0001] The present invention relates to the technical field of vehicle parts, and in particular to a frameless vehicle door bright strip assembly and an assembling method thereof. Background Art

[0002] Frameless doors eliminate the traditional door frame structure and instead seal the window glass directly against the bright strip. When the window glass is closed, its upper end contacts the bright strip, creating a seal. Compared to traditional framed doors, frameless doors offer the advantage of being lighter, giving the vehicle a more streamlined and stylish appearance, and enhancing its sporty feel. Consequently, they are widely used in models such as coupes and sports cars.

[0003] The bright strip is the core structure of frameless doors, and the accuracy of its installation will directly affect the vehicle's sealing performance. Since the bright strip is overall long and has a certain curvature, it is difficult to position and install it. In addition, since the door and window glass will be frequently raised and lowered during vehicle use, improper installation of the bright strip will easily cause water leakage between it and the door and window glass, affecting the overall aesthetics of the vehicle and NVH (Noise, Vibration, Harshness) performance. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a frameless door bright strip assembly and assembly method. The bright strip body cooperates with the corner window glass to provide a positioning reference for the installation of the bright strip body, reducing the difficulty of assembly, which is beneficial to improving the sealing performance of the vehicle and is simple and convenient to operate.

[0005] The present invention provides a frameless vehicle door bright strip assembly for cooperating with the door window glass and corner window glass of a vehicle, wherein the door window glass is configured to be able to be raised and lowered, and comprises a bright strip body, a first seal and a second seal, wherein the bright strip body is mounted on a side panel and extends from the door window glass to the corner window glass, wherein the first seal is connected to one end of the bright strip body close to the vehicle window glass so that the bright strip body can be in sealing contact with the vehicle window glass, wherein the second seal is connected to one end of the bright strip body close to the corner window glass so that the bright strip body is in sealing connection with the corner window glass, and the front end of the second seal is in contact with or connected to the rear end of the first seal.

[0006] In one embodiment, the bright strip body includes a connecting section and an extending section, the connecting section extends from the door window glass to the corner window glass, the extending section cooperates with the door window glass, and the connecting section cooperates with the extending section to connect with the first seal.

[0007] In one embodiment, the connecting section includes a first base member and a second base member, and one end of the second base member is connected to a side of the first base member away from an outer surface thereof.

[0008] In one embodiment, an insert is protruding from one end of the first base member away from the outer surface thereof, the insert is located on a side of the second base member away from the side panel in the Z direction, and is spaced apart from the second base member, and the insert is used to cooperate with the first seal and the second seal.

[0009] In one embodiment, a first positioning member is protruding from one end of the first base member away from the outer surface thereof, the first positioning member is located on a side of the second base member close to the side panel metal in the Z direction, and is spaced apart from the second base member, and a second positioning member is protruding from one end of the second base member close to the side panel metal, the first positioning member and the second positioning member cooperate to form a positioning groove, and fixing glue is provided in the positioning groove.

[0010] In one embodiment, the extension section includes a third base member and a limiting member, one end of the third base member is connected to the second base member, and the other end is connected to the limiting member, the distance between the third base member and the side panel sheet metal is smaller than the distance between the second base member and the side panel sheet metal, the third base member is used to be connected to the side panel sheet metal, and the limiting member is used to be connected to the first sealing member.

[0011] In one embodiment, the second sealing member includes a first component and a second component, and the hardness of the first component is greater than the hardness of the second component.

[0012] In one embodiment, the first component includes a protrusion, which protrudes and extends toward one end close to the first base component and cooperates with the insert, or the first component includes a first embedding groove, which is used to accommodate the insert.

[0013] In one embodiment, the second component includes a second embedding groove, and the second embedding groove cooperates with the second base member. When the second sealing member is connected to the connecting section, the second base member is embedded in the second embedding groove.

[0014] The present invention also provides a method for assembling a frameless vehicle door bright strip assembly, which is used to assemble the above-mentioned frameless vehicle door bright strip assembly, comprising the following steps: Install the second seal: Connect the second seal to the corner window glass and install the second seal along the Y direction to the corner window side of the bright strip body; Install the corner window glass: Fix the corner window glass to the vehicle body; Install the corner window side of the bright strip body: Fix the corner window side of the bright strip body to the corner window side of the side panel; Install the first seal: Install the first seal along the Y direction to the door and window side of the bright strip body; Install the door and window side of the bright strip body: Fix the door and window side of the bright strip body to the door and window side of the side panel metal.

[0015] The beneficial effects of the present invention are: The bright strip body is configured to extend from the door and window glass to the corner window glass, which can realize the installation and fixation of the first seal and the second seal. Through the cooperation of the bright strip body, the second seal and the corner window glass, a positioning reference can be provided for the subsequent installation of the bright strip body to ensure the installation accuracy of the bright strip body and the door and window glass and the door and window side of the side panel metal, which reduces the assembly difficulty and the assembly process, and is conducive to improving the installation efficiency and installation quality; contacting or connecting the first seal and the second seal can cooperate with the bright strip body to improve the sealing performance and prevent external rain and snow water from entering the vehicle interior through the bright strip body.

[0016] In the prior art, bright strips are usually manufactured separately for door and window glass and corner window glass, and the bright strips of the door and window glass and the bright strips of the corner window glass are assembled and docked during installation. Such docking-type bright strips may have differences in production processes, manufacturers, etc., which will cause poor installation accuracy at the door and window glass, and are greatly affected by dimensional errors. The frameless door bright strip assembly proposed by the present invention can avoid the problem of docking misalignment caused by dimensional errors, production processes, etc., and thus avoid the problem of gaps and water leakage at the docking points, and also avoid the problem of abnormal noise caused by friction and displacement at the docking points of the bright strips during vehicle driving, which is beneficial to improving the sealing performance and NVH performance. Compared with docking-type bright strips, the mold opening process is reduced, thereby reducing production costs.

[0017] Due to the complex driving environment of the vehicle, the bright strip will be affected by the environment and expand and contract with heat. If a butt-jointed bright strip is used, the bright strip will move in the X direction, thereby causing a gap between the bright strip of the door and window glass and the bright strip of the corner window glass. Rain and snow water will corrode the sealing strip at the bright strip through the gap, thereby causing water seepage and leakage problems in the vehicle. The bright strip body of the present invention extends to the corner window glass and cooperates with the corner window glass to achieve installation positioning on the corner window side, and then connects to the door and window side of the side panel metal, thereby improving installation accuracy while preventing water seepage and leakage problems between the door and window glass and the corner window glass.

DETAILED DESCRIPTION

[0026] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, and not all, of the embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the description of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0027] Unless otherwise specified or limited, the terms "disposed," "installed," and "connected" should be interpreted broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms based on the specific circumstances.

[0028] The directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when in use. They are only for the convenience and simplification of description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0029] The terms "first," "second," "third," etc. are merely used to distinguish elements of similar nature and do not indicate or imply relative importance or a particular order.

[0030] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of elements other than the listed elements and may also include additional elements not specifically listed.

[0031] The positional relationship and connection relationship of each component in the present invention are referenced to the vehicle coordinate system. The vehicle coordinate system is a special dynamic coordinate system used to describe the movement of a vehicle. The origin of this coordinate system coincides with the center of mass of the vehicle. When the vehicle is stationary on a horizontal road, the X direction of this coordinate system refers to the direction parallel to the direction of travel of the vehicle, that is, the front-to-back direction. The Y direction refers to the width direction of the vehicle. The Z direction refers to the height direction of the vehicle, that is, the up-down direction.

[0032] like Figure 1 As shown, the frameless door bright strip assembly proposed in the present invention is used to cooperate with the door and window glass 102 and the corner window glass 103 of the vehicle. More specifically, it can be in sealing contact with the door and window glass 102 and sealed connected to the corner window glass 103. The door and window glass 102 is configured to be able to be raised and lowered to realize the opening and closing of doors and windows. More specifically, the door and window glass 102 can be raised and lowered relative to the frameless door bright strip assembly proposed in the present invention. When the door and window glass 102 is lowered, the window opening action is realized. When the door and window glass 102 is raised to be in sealing contact with the frameless door bright strip assembly proposed in the present invention, the window closing action is realized.

[0033] Since the door and window glass 102 can be raised and lowered, the X-dimension of the door and window glass 102 is relatively large, which will make the length dimension of the bright strip assembly in the X-direction larger. Moreover, since the bright strip assembly has a certain curvature, it brings difficulty to positioning during installation. If the positioning is not accurate, it will not only affect the overall aesthetics of the vehicle, but also easily lead to poor sealing between it and the door and window glass 102 and / or the corner window glass 103, making the vehicle prone to water seepage and leakage problems, and also affecting the NVH performance of the vehicle.

[0034] Combine Figure 1 、 Figure 4 and Figure 5The frameless door bright strip assembly proposed in the present invention includes a bright strip body 10, a first seal 20 and a second seal 30. The bright strip body 10 is installed on the side panel 101 of the vehicle body and extends from the door window glass 102 to the corner window glass 103. The first seal 20 is connected to the end of the bright strip body 10 close to the door window glass 102, so that the bright strip body 10 can be in sealing contact with the door window glass 102. The second seal 30 is connected to the end of the bright strip body 10 close to the corner window glass 103, so that the bright strip body 10 and the corner window glass 103 are sealed. The front end of the second seal 30 is in contact with or connected to the rear end of the first seal 20.

[0035] It can be understood that since the bright strip body 10 extends from the door and window glass 102 to the corner window glass 103, it has a door and window side that cooperates with the door and window glass 102, and a corner window side that cooperates with the corner window glass 103. The following "door and window side" and "corner window side" are based on the position and cooperation relationship of the bright strip body 10 and / or the side panel 101 relative to the two.

[0036] The bright strip body 10 is configured to extend from the door and window glass 102 to the corner window glass 103, which can realize the installation and fixation of the first seal 20 and the second seal 30. Through the cooperation of the bright strip body 10, the second seal 30 and the corner window glass 103, a positioning reference can be provided for the subsequent installation of the bright strip body 10 to ensure the installation accuracy of the bright strip body 10 and the door and window glass 102 and the door and window side of the side panel 101, thereby reducing the assembly difficulty and the assembly process, which is conducive to improving the installation efficiency and installation quality; the first seal 20 and the second seal 30 are contacted or connected, which can cooperate with the bright strip body 10 to improve the sealing performance and prevent external rain and snow water from entering the vehicle interior through the bright strip body 10.

[0037] In the prior art, bright strips are usually manufactured separately for the door and window glass 102 and the corner window glass 103. During installation, the bright strips of the door and window glass 102 and the bright strips of the corner window glass 103 are assembled and docked. Such docking-type bright strips may have differences in production processes, manufacturers, etc., which may cause poor installation accuracy at the door and window glass 102 and be greatly affected by dimensional errors. The frameless door bright strip assembly proposed by the present invention can avoid the problem of docking misalignment caused by dimensional errors, production processes, etc., and thus avoid the problem of gaps and water leakage at the docking points, and also avoid the problem of abnormal noise caused by friction and displacement at the docking points of the bright strips during vehicle driving, which is beneficial to improving the sealing performance and NVH performance. Compared with docking-type bright strips, the mold opening process is reduced, thereby reducing production costs.

[0038] Due to the complex driving environment of the vehicle, the bright strip will be affected by the environment and expand and contract with heat. If a docking bright strip is used, the bright strip will move in the X direction, thereby causing a gap between the bright strip of the door and window glass 102 and the bright strip of the corner window glass 103. Rain and snow water will corrode the sealing strip at the bright strip through the gap, thereby causing water seepage and leakage problems in the vehicle. The bright strip body 10 of the present invention extends to the corner window glass 103 and cooperates with the corner window glass 103 to achieve installation positioning on the corner window side, and then connects to the door and window side of the side panel 101. While improving the installation accuracy, it will not cause water seepage and leakage problems between the door and window glass 102 and the corner window glass 103.

[0039] In one embodiment, combining Figure 1 and Figure 2 The bright strip body 10 includes a connecting section 11 and an extending section 12. The connecting section 11 extends from the door window glass 102 to the corner window glass 103 in the X direction. The connecting section 11 can simultaneously connect with the door window glass 102 and the corner window glass 103. The extending section 12 cooperates with the door window glass 102. More specifically, the position of the extending section 12 cooperates with the door window glass 102. Figure 4 and Figure 5 The connecting section 11 is connected to the second sealing member 30 , the extending section 12 is connected to one side of the connecting section 11 , and the connecting section 11 cooperates with the extending section 12 to be connected to the first sealing member 20 .

[0040] In one example of this embodiment, the connecting section 11 and the extending section 12 are integrally formed. In another example of this embodiment, the connecting section 11 and the extending section 12 are separately formed and connected as one body.

[0041] For example, the bright strip body 10 is made of aluminum, and is formed into an integrated connecting section 11 and an extension section 12 extending to the corner window glass 103 through an extrusion process. The extension section 12 is then cut through a punching process so that the extension section 12 cooperates with the door and window glass 102, which is easy to process.

[0042] In one embodiment, combining Figure 3 、 Figure 4 and Figure 5 The connecting section 11 includes a first base member 111 and a second base member 112. The first base member 111 extends roughly along the X direction of the vehicle, and the second base member 112 extends roughly along the Y direction of the vehicle. The outer surface 111a of the first base member 111 cooperates with the side panel 101 to constitute a part of the vehicle body surface. The outer surface 111a can beautify and decorate the appearance. One end of the second base member 112 is connected to the side of the first base member 111 away from its outer surface 111a. The first base member 111 and the second base member 112 cooperate to be connected to the second seal 30, and to cooperate with the extension section 12 to be connected to the first seal 20.

[0043] In this embodiment, the Figure 4 and Figure 5 The first base member 111 is bent in the Z direction at one end away from the side panel 101 toward the side away from its outer surface 111a, and contacts the first seal 20 and the second seal 30 respectively, so as to shield the first seal 20 and the second seal 30 and prevent the first seal 20 and the second seal 30 from being exposed.

[0044] In this embodiment, the Figure 4 and Figure 5 An insert 113 is protruded from one end of the first base member 111 away from its outer surface 111a. The insert 113 is located on the side of the second base member 112 away from the side panel 101 in the Z direction, and is spaced apart from the second base member 112. The insert 113 extends roughly along the Y direction. The insert 113 is used to cooperate with the first seal 20 and the second seal 30 to position and connect the two in the Y direction, which can improve the assembly efficiency of the first seal 20 and the second seal 30.

[0045] In this example, if Figure 4 As shown, the first seal 20 includes a first embedding groove 21, which cooperates with the insert 113. When the first seal 20 is connected to the connecting section 11, the insert 113 is installed in the first embedding groove 21 to enable the first seal 20 and the connecting section 11 to be positioned and connected in the Y direction.

[0046] In this example, if Figure 5 As shown, the second seal 30 includes a protrusion 31, which protrudes and extends toward one end close to the first base member 111 and cooperates with the insert 113. When the second seal 30 is connected to the connecting section 11, the protrusion 31 is located at the upper end of the insert 113 and contacts the insert 113 and the first base member 111. The insert 113 can fix the second seal 30 in the Z direction, and the first base member 111 can fix the second seal 30 in the Y direction, which is beneficial to ensuring the connection quality of the second seal 30. Alternatively, the second seal 30 includes a first embedding groove 21 that cooperates with the insert 113 to accommodate the insert 113.

[0047] In this embodiment, the Figure 4 and Figure 5A first positioning member 114 is protruding from one end of the first base member 111 away from its outer surface 111a. The first positioning member 114 is located on the side of the second base member 112 close to the side panel 101 and is spaced apart from the second base member 112. A second positioning member 115 is protruding from the end of the second base member 112 close to the side panel 101. The first positioning member 114 and the second positioning member 115 cooperate to form a positioning groove 116. The positioning groove 116 has an opening on the side close to the side panel 101. A fixing glue 117 is provided in the positioning groove 116. The fixing glue 117 can realize the connection and fixation between the connecting section 11 and the side panel 101, and the fixing glue 117 can also realize the sealing connection between the connecting section 11 and the side panel 101.

[0048] Exemplarily, at least one of the first positioning member 114 and the second positioning member 115 is tilted, or has a bending member at the end, so that the opening of the positioning groove 116 is closed, so as to facilitate embedding and fixing the fixing glue 117 in the positioning groove 116.

[0049] For example, the fixing glue 117 is in the form of a glue strip, and the fixing glue 117 extends from the door and window side of the bright strip body 10 to the corner window side thereof, which simplifies the bonding process and helps to improve assembly efficiency.

[0050] In this example, if Figure 5 As shown, the second sealing member 30 also includes a second embedding groove 32, which cooperates with the second base member 112. When the second sealing member 30 is connected to the connecting section 11, the second base member 112 is embedded in the second embedding groove 32. The second embedding groove 32 cooperates with the protrusion 31 or the first embedding groove 21 of the second sealing member 30, and can limit and fix the second sealing member 30 in the Y direction, thereby realizing a fixed connection between the second sealing member 30 and the connecting section 11.

[0051] For example, Figure 5 As shown, at least one lip structure 321 is protruded from the groove wall of the second embedding groove 32. When the second base member 112 is embedded in the second embedding groove 32, the lip structure 321 contacts the second base member 112 and deforms to fix the second base member 112 in the second embedding groove 32, thereby avoiding the problem of the second sealing member 30 being displaced relative to the second base member 112, which is beneficial to improving the reliability of the installation of the second sealing member 30 and ensuring the connection strength.

[0052] Furthermore, lip structures 321 are protruded from the groove walls of the second embedding groove 32 located on both sides of the second base member 112 to ensure that the second sealing member 30 is installed firmly and reliably.

[0053] In one embodiment, if Figure 5As shown, the second sealing component 30 includes a first component 301 and a second component 302, and the hardness of the first component 301 is greater than the hardness of the second component 302. Such a configuration can improve the overall structural strength of the second sealing component 30, which is beneficial to improving the sealing performance.

[0054] In this embodiment, the first component 301 and the second component 302 are both made of TPV (Thermoplastic Vulcanizate).

[0055] In an example of this embodiment, the aforementioned protrusion 31 or the first embedding groove 21 is provided on the first component 301, so that it is not easy to deform when cooperating with the insert 113, which is equivalent to the insert 113 shifting, which is beneficial to improving the stability of the installation. The bending part of the first base member 111 is in contact with the first component 301.

[0056] In this embodiment, the second embedding groove 32 is opened on the second component 302, which can stabilize the connection between the second base member 112 and the second embedding groove 32 and make the lip structure 321 easy to deform, thereby fixing the second base member 112 in the second embedding groove 32 through the lip structure 321.

[0057] In this embodiment, the first component 301 , the second component 302 and the corner window glass 103 are integrally connected through a multi-color injection molding process.

[0058] In one embodiment, combining Figure 3 and Figure 4 The extension section 12 includes a third base member 121 and a limit member 122. One end of the third base member 121 is connected to the second base member 112, and the other end is connected to the limit member 122. The distance between the third base member 121 and the side panel 101 is smaller than the distance between the second base member 112 and the side panel 101. The third base member 121 is used to connect to the door and window side of the side panel 101, and the limit member 122 is cooperated with the first sealing member 20 for connection. By setting the distance between the third base member 121 and the second base member 112, the connecting section 11 can be adapted to the door and window side and the corner window side of the side panel 101 at the same time, and it is beneficial to connect the third base member 121 to the door and window side of the side panel 101.

[0059] In this embodiment, the Figure 3 and Figure 4The extension section 12 also includes an adapter 123, one end of the adapter 123 is connected to the third base member 121, and the other end is connected to the second base member 112. The adapter 123, the second positioning member 115 and the second base member 112 cooperate to form a slot, and a water-proof seal 118 is installed in the slot. The water-proof seal 118 is used to contact the door and window side of the side panel 101. The adapter 123 cooperates with the second positioning member 115 to limit the water-proof seal 118 in the Y direction, which is beneficial to ensure that the installation of the water-proof seal 118 is stable and firm to prevent displacement. The water-proof seal 118 cooperates with the fixing glue 117 to play a waterproof and dustproof role, which is beneficial to improve the sealing and firmness of the connection between the door and window side of the bright strip body 10 and the door and window side of the side panel 101.

[0060] For example, the water-proof seal 118 is made of waterproof foam. Figure 3 and Figure 4 A mounting hole 1211 is provided on the third base member 121, and an assembly hole matching the mounting hole 1211 is provided on the side panel 101. The mounting member 1212 is passed through the mounting hole 1211 and the assembly hole to realize the connection between the third base member 121 and the side panel 101 in the Z direction.

[0061] Exemplarily, the mounting member 1212 is a rivet.

[0062] In this embodiment, the Figure 3 and Figure 4 The end of the limiting member 122 away from the third base member 121 is protruded with a clamping member 124, which extends roughly along the Y direction. The first sealing member 20 is protruded with two opposite clamping members 22 at the end close to the limiting member 122. When the first sealing member 20 is connected to the extension section 12, the clamping member 124 is passed between the two clamping members 22. The clamping member 22 cooperates with the clamping member 124, the first embedding groove 21 and the embedding member 113, and can fix the first sealing member 20 to the bright strip body 10 in the Y direction, and can prevent the first sealing member 20 from shifting in the Z direction. When the door and window glass 102 is raised or lowered, the first sealing member 20 can maintain structural stability, effectively avoiding water leakage.

[0063] For example, Figure 4 As shown, one of the clamping members 22 contacts the side of the limiting member 122 close to the first base member 111 , and the limiting member 122 cooperates with the first base member 111 to limit the first sealing member 20 in the Y direction.

[0064] For example, Figure 4 As shown, the upper end of the first sealing member 20 contacts the second base member 112 to limit the first sealing member 20 in the Z direction to prevent the first sealing member 20 from moving in the Z direction.
