Description

Technical Field

[0001] This utility model relates to the field of lifting window technology, and in particular to a double-fork arm type guide rail sliding lifting window. Background Technology

[0002] As a core component of car doors, car windows serve functions such as lighting and ventilation. Currently, car windows typically use a lift-type design, where a window regulator drives the glass to move up and down along the door rails to open and close the window.

[0003] During the raising and lowering of car windows, the window glass rubs against the sealing strip at the door frame. When the contact pressure between the window glass and the sealing strip is uneven, the local friction between the window glass and the sealing strip will be further aggravated, accelerating the wear of both the sealing strip and the glass. Utility Model Content

[0004] In order to delay the wear of the sealing strip, this application provides a double-fork arm type guide rail sliding lift window.

[0005] The technical solution for a double-wishbone type sliding lift window provided in this application is as follows: A double-fork arm type sliding lift window includes an outer frame, an inner frame fixedly mounted on one side of the outer frame, an upper wheel frame and a lower wheel frame slidably mounted inside the inner frame, a glass body being mounted on both the upper and lower wheel frames, a sealing strip being fixedly mounted on the outer frame facing the glass body, the sealing strip being used to abut against the glass body, a set of guide components being provided inside the inner frame, the guide components being arranged opposite each other, the guide components being used to move the glass body away from the outer frame when it descends, and a plurality of fisheye connecting rods being provided at the bottom of the lower wheel frame, the bottom ends of the fisheye connecting rods being provided with a lifting crossbeam.

[0006] By adopting the above technical solution, the outer frame and inner frame are installed on the car door. When the window is closed, the lifting beam drives the glass body, upper wheel frame, and lower wheel frame to rise synchronously. When the window is closed, the glass body is offset 8mm towards the outer frame under the action of the guide component. At the same time, the spherical connecting rod provides the glass body with the freedom to offset towards the outer frame, thereby achieving the sealing function by squeezing the sealing strip. When the window is opened, the lifting beam drives the glass body, upper wheel frame, and lower wheel frame to fall synchronously. The glass body moves away from the outer frame under the action of the guide component. At the same time, the spherical connecting rod provides the glass body with the freedom to move away from the outer frame, reducing the friction between the glass body and the sealing strip, thus delaying the wear of the sealing strip.

[0007] Preferably, the guide assembly includes an upper guide rail, an upper inclined rail, and an upper guide wheel. The upper guide rail and the upper inclined rail are both fixedly mounted on the inner frame. The top end of the upper guide rail is connected to the bottom end of the upper inclined rail. The upper guide rail is vertically mounted, and the upper inclined rail is inclined. The bottom end of the upper inclined rail is away from the outer frame, and the top end of the upper inclined rail is close to the outer frame. The upper guide wheel is rotatably mounted inside the upper guide rail and the upper inclined rail, and the upper guide wheel is rotatably connected to the upper wheel frame.

[0008] By adopting the above technical solution, when the glass body and the upper wheel frame move synchronously, the upper guide wheel rolls in the upper guide rail and the upper inclined rail. When the upper guide wheel rolls along the upper guide rail, the glass body and the upper wheel frame move in the vertical direction. When the upper guide wheel rolls along the upper inclined rail, the glass body and the upper wheel frame shift in the horizontal direction.

[0009] Preferably, the guide assembly further includes a lower guide rail, a lower inclined rail, and a lower guide wheel. The lower guide rail and the lower inclined rail are both fixedly mounted on the inner frame. The top end of the lower guide rail is connected to the bottom end of the lower inclined rail. The lower guide rail is vertically mounted, and the lower inclined rail is inclined. The bottom end of the lower inclined rail is away from the outer frame, and the top end of the lower inclined rail is close to the outer frame. The lower guide wheel is rotatably mounted inside the lower guide rail and the lower inclined rail, and the lower guide wheel is rotatably connected to the lower wheel frame.

[0010] By adopting the above technical solution, when the glass body and the lower wheel frame move synchronously, the lower guide wheel rolls in the lower guide rail and the lower inclined rail. When the lower guide wheel rolls along the lower guide rail, the glass body and the lower wheel frame move in the vertical direction. When the lower guide wheel rolls along the lower inclined rail, the glass body and the lower wheel frame shift in the horizontal direction.

[0011] Preferably, the upper guide rail and the lower guide rail are arranged collinearly, the upper inclined rail and the lower inclined rail are arranged parallel to each other, the length of the upper guide rail is equal to the length of the lower guide rail, the length of the upper inclined rail is equal to the length of the lower inclined rail, the length of the upper guide rail is greater than the length of the upper inclined rail, and the length of the lower guide rail is greater than the length of the lower inclined rail.

[0012] By adopting the above technical solution, when the upper guide wheel rolls in the upper guide rail, the lower guide wheel rolls in the lower guide rail. At this time, the squeezing force of the glass body on the sealing strip is the first squeezing force. When the upper guide wheel rolls in the upper inclined rail, the lower guide wheel rolls in the lower inclined rail. At this time, the squeezing force of the glass body on the sealing strip is the second squeezing force. Since the upper guide rail is farther away from the sealing strip relative to the upper inclined rail, and the lower guide rail is farther away from the sealing strip relative to the lower inclined rail, the second squeezing force is not less than the first squeezing force.

[0013] Preferably, a second rotating arm and a third rotating arm are movably arranged on the lifting beam, the second rotating arm and the third rotating arm are arranged crosswise and rotatably connected. An interior panel is arranged below the inner frame, a drive shaft is rotatably arranged on the interior panel, a drive arm is fixedly arranged on the drive shaft, and the drive arm is rotatably connected to the third rotating arm. A first rotating arm is movably arranged on the interior panel, the first rotating arm is rotatably connected to the second arm, the first rotating arm is arranged crosswise and rotatably connected to the drive arm.

[0014] By adopting the above technical solution, the drive arm, the first rotating arm, the second rotating arm and the third rotating arm together form a scissor-type structure. When the drive shaft rotates and drives the drive arm to rotate, the lifting beam moves relative to the interior panel installed on the door under the combined action of the drive arm, the first rotating arm, the second rotating arm and the third rotating arm.

[0015] Preferably, a drive motor is fixedly mounted on the interior trim panel, a drive worm is fixedly mounted on the output shaft of the drive motor, a drive worm wheel is rotatably mounted on the interior trim panel, the drive worm wheel meshes with the drive worm, a drive gear is fixedly mounted on the drive worm wheel, a drive sector tooth is sleeved on the drive shaft, the drive sector tooth is fixedly connected to the drive shaft, and the drive sector tooth meshes with the drive gear.

[0016] By adopting the above technical solution, the drive motor starts and drives the drive worm to rotate, the drive worm to rotate, the drive worm wheel to rotate, the drive gear to rotate, the drive sector gear to rotate, and the drive sector gear to rotate.

[0017] Preferably, a lower slide rail is fixedly provided on the interior panel, and a lower slide block is slidably provided in the lower slide rail, the lower slide block being rotatably connected to the first rotating arm.

[0018] By adopting the above technical solution, when the first rotating arm and the drive arm rotate relative to each other, the first rotating arm and the lower slider rotate relative to each other, and the lower slider moves along the lower slide rail.

[0019] Preferably, a set of upper sliders is slidably arranged on the lifting beam, wherein one upper slider is rotatably connected to the second rotating arm and the other upper slider is rotatably connected to the third rotating arm.

[0020] By adopting the above technical solution, when the second rotating arm and the third rotating arm rotate relative to each other, the upper slider, the second rotating arm and the third rotating arm rotate relative to each other, and the upper slider moves along the lifting beam.

By setting up an upper guide rail, an upper inclined rail, an upper guide wheel, a lower guide rail, a lower inclined rail, and a lower guide wheel, the glass body is offset in the horizontal direction; 3. The glass body can be raised and lowered by setting up an interior panel, drive shaft, drive arm, first rotating arm, second rotating arm and third rotating arm. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0031] This application discloses a double-fork arm type guide rail sliding lift window. (Refer to...) Figures 1 to 4 The system includes an outer frame 1, with an inner frame 2 installed on one side of the outer frame 1. The outer frame 1 and the inner frame 2 are mounted on the car door. An upper wheel bracket 31 and a lower wheel bracket 32 ​​are slidably mounted within the inner frame 2, with the upper wheel bracket 31 positioned above the lower wheel bracket 32. A glass body 3 is mounted on both the upper wheel bracket 31 and the lower wheel bracket 32. A D-shaped sealing strip 11 is installed on the side of the outer frame 1 facing the glass body 3, and the sealing strip 11 is used to abut against the glass body 3. A set of guide components 4 are installed within the inner frame 2, with the guide components 4 positioned opposite each other, and the guide components 4 are used to move the glass body 3 away from the outer frame 1 when it descends. Several spherical connecting rods 5 are installed at the bottom of the lower wheel bracket 32, and a lifting crossbeam 51 is installed at the bottom of the spherical connecting rods 5. When the car window is closed, the lifting crossbeam 51 causes the glass body 3, the upper wheel bracket 31, and the lower wheel bracket 32 ​​to rise synchronously. When the window is closed, the glass body 3 is offset 8mm towards the outer frame 1 under the action of the guide assembly 4. At the same time, the spherical connecting rod 5 provides the glass body 3 with the freedom to offset towards the outer frame 1, thereby achieving the sealing function by compressing the sealing strip 11. When the window is opened, the lifting beam 51 drives the glass body 3, the upper wheel frame 31, and the lower wheel frame 32 to descend synchronously. Under the action of the guide assembly 4, the glass body 3 moves away from the outer frame 1. At the same time, the spherical connecting rod 5 provides the glass body 3 with the freedom to move away from the outer frame 1, reducing the friction between the glass body 3 and the sealing strip 11, thereby delaying the wear of the sealing strip 11.

[0032] Reference Figures 1 to 4The guide assembly 4 includes an upper guide rail 41, an upper inclined rail 42, an upper guide wheel 43, a lower guide rail 44, a lower inclined rail 45, and a lower guide wheel 46. The upper guide rail 41, upper inclined rail 42, lower guide rail 44, and lower inclined rail 45 are all mounted on the inner frame 2. The upper guide wheel 43 is rotatably disposed within the upper guide rail 41 and the upper inclined rail 42, and is rotatably connected to the upper wheel frame 31. The lower guide wheel 46 is rotatably disposed within the lower guide rail 44 and the lower inclined rail 45, and is rotatably connected to the lower wheel frame 32. The upper inclined rail 42 is located above the upper guide rail 41, the upper guide rail 41 is located above the lower inclined rail 45, and the lower inclined rail 45 is located above the lower guide rail 44. The top end of the upper guide rail 41 is connected to the bottom end of the upper inclined rail 42, and the top end of the lower guide rail 44 is connected to the bottom end of the lower inclined rail 45. The upper guide rail 41 is the same length as the lower guide rail 44, and the upper inclined rail 42 is the same length as the lower inclined rail 45. The upper guide rail 41 is longer than the upper inclined rail 42, and the lower guide rail 44 is longer than the lower inclined rail 45. Both the upper and lower guide rails 41 and 44 are vertically aligned and collinear. Both the upper and lower inclined rails 42 and 45 are inclined and parallel to each other. The bottom ends of both the upper and lower inclined rails 42 and 45 are far from the outer frame 1, while the top ends of both are close to the outer frame 1. When the glass body 3, the upper wheel frame 31, and the lower wheel frame 32 move synchronously, the upper guide wheel 43 rolls within the upper guide rail 41 and the upper inclined rail 42, and the lower guide wheel 46 rolls within the lower guide rail 44 and the lower inclined rail 45. When the upper guide wheel 43 rolls along the upper guide rail 41, the lower guide wheel 46 rolls along the lower guide rail 44, and the glass body 3 moves vertically. At this time, the pressure exerted by the glass body 3 on the sealing strip 11 is the first pressure. When the upper guide wheel 43 rolls along the upper inclined rail 42, the lower guide wheel 46 rolls within the lower inclined rail 45, and the glass body 3 and the upper wheel frame 31 shift horizontally. At this time, the pressure exerted by the glass body 3 on the sealing strip 11 is the second pressure. Since the upper guide rail 41 is farther away from the sealing strip 11 relative to the upper inclined rail 42, and the lower guide rail 44 is farther away from the sealing strip 11 relative to the lower inclined rail 45, the second pressure is not less than the first pressure. When the window is closed, the upper guide wheel 43 moves from the upper guide rail 41 into the upper inclined rail 42, and the lower guide wheel 46 moves from the lower guide rail 44 into the lower inclined rail 45. Under the action of the upper inclined rail 42 and the lower inclined rail 45, the glass body 3 shifts 8mm towards the outer frame 1, thereby compressing the sealing strip 11 to achieve the sealing function. During the opening of the car window, the upper guide wheel 43 enters the upper guide rail 41 from the upper inclined rail 42, and the lower guide wheel 46 enters the lower guide rail 44 from the lower inclined rail 45, so that the glass body 3 is away from the outer frame 1, reducing the friction between the glass body 3 and the sealing strip 11, thereby delaying the wear of the sealing strip 11.

[0033] Reference Figures 1 to 6An interior trim panel 21 is installed below the inner frame 2 and is fixed inside the door. A drive shaft 65 and a lower slide rail 74 are mounted on the interior trim panel 21. The drive shaft 65 is rotatably connected to the interior trim panel 21, and the lower slide rail 74 is fixedly connected to the interior trim panel 21. A sliding block 75 is slidably mounted on the lower slide rail 74. A drive arm 7 is mounted on the drive shaft 65, with the drive shaft 65 close to the bottom end of the drive arm 7. A first rotating arm 71 is rotatably mounted on the sliding block 75, with the sliding block 75 close to the bottom end of the first rotating arm 71. The first rotating arm 71 is crossed with the drive arm 7 and is rotatably connected to the drive arm 7. When the first rotating arm 71 and the drive arm 7 rotate relative to each other, the first rotating arm 71 and the sliding block 75 rotate relative to each other, and the sliding block 75 moves along the lower slide rail 74. A set of upper sliders 76 are slidably mounted on the lifting beam 51. A second rotating arm 72 and a third rotating arm 73 are rotatably mounted on the upper sliders 76, with one upper slider 76 near the top of the second rotating arm 72 and the other near the top of the third rotating arm 73. The second and third rotating arms 72 and 73 are arranged crosswise and rotatably connected. When the second and third rotating arms 72 and 73 rotate relative to each other, the upper sliders 76, the second rotating arm 72, and the third rotating arm 73 also rotate relative to each other, and the upper sliders 76 move along the lifting beam 51. The first rotating arm 71 and the second rotating arm 72 are rotatably connected, and the drive arm 7 and the third rotating arm 73 are rotatably connected. The drive arm 7, the first rotating arm 71, the second rotating arm 72, and the third rotating arm 73 together form a scissor lift structure. When the drive shaft 65 rotates and drives the drive arm 7 to rotate, the lifting beam 51 moves relative to the interior panel 21 installed on the door under the combined action of the drive arm 7, the first rotating arm 71, the second rotating arm 72 and the third rotating arm 73.

[0034] Reference Figures 5 to 7 A drive motor 6 is mounted on the interior trim panel 21, and a drive worm gear 61 is mounted on the output shaft of the drive motor 6. A drive worm wheel 62 is rotatably mounted on the interior trim panel 21, and the drive worm wheel 62 meshes with the drive worm gear 61. A drive sector gear 64 is sleeved on the drive shaft 65, and the drive sector gear 64 is fixedly connected to the drive shaft 65. A drive gear 63 is mounted on the drive worm wheel 62, and the drive gear 63 meshes with the drive sector gear 64. When the drive motor 6 starts, it drives the drive worm gear 61 to rotate, which in turn drives the drive worm wheel 62 to rotate, which in turn drives the drive gear 63 to rotate, which in turn drives the drive sector gear 64 to rotate, and finally, the drive shaft 65 to rotate.

[0035] The implementation principle of a double-fork arm type guide rail sliding lift window in this application embodiment is as follows: When the window is closed, the lifting beam 51 drives the glass body 3, the upper wheel frame 31 and the lower wheel frame 32 to rise synchronously. The upper guide wheel 43 enters the upper inclined rail 42 from the upper guide rail 41, and the lower guide wheel 46 enters the lower inclined rail 45 from the lower guide rail 44. Under the action of the upper inclined rail 42 and the lower inclined rail 45, the glass body 3 is offset 8mm towards the outer frame 1. At the same time, the fisheye connecting rod 5 provides the glass body 3 with the freedom to offset towards the outer frame 1, thereby achieving the sealing function by squeezing the sealing strip 11. When the car window is opened, the lifting beam 51 drives the glass body 3, the upper wheel frame 31 and the lower wheel frame 32 to descend synchronously. The upper guide wheel 43 enters the upper guide rail 41 from the upper inclined rail 42, and the lower guide wheel 46 enters the lower guide rail 44 from the lower inclined rail 45, so that the glass body 3 is away from the outer frame 1. At the same time, the fisheye connecting rod 5 provides the glass body 3 with a degree of freedom in the direction away from the outer frame 1, so that the friction between the glass body 3 and the sealing strip 11 is reduced, thereby delaying the wear of the sealing strip 11.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
