Description

Technical Field

[0001] This utility model relates to the field of opening and closing mechanism technology, specifically to an opening and closing mechanism for a dual-axis electric window. Background Technology

[0002] Car side windows, installed on the doors, effectively allow for air circulation inside the vehicle, increasing the intake of fresh air and providing a healthy and comfortable experience for the occupants. They also offer a wider field of vision and are often used for mobile photography and videography. Existing car windows are divided into manual and electric types. Manually opening and closing a sunroof can negatively impact the driving experience and driver attention, potentially causing unnecessary accidents or distraction, thus affecting vehicle operation. Current electric sunroofs use a pair of flexible shafts for drive, located on either side of the sunroof and driven by motors. However, dual flexible shafts require two motors to open and close simultaneously, which can easily lead to inconsistent actions and cause the sunroof to jam. Utility Model Content

[0003] The purpose of this utility model is to provide an opening and closing mechanism for a dual-axis electric window, which solves the problem that dual flexible shafts require the use of dual motors for simultaneous opening and closing, which can easily lead to inconsistent actions and cause the window to jam when opening or closing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an opening and closing mechanism for a dual-axis electric window, comprising a fixed frame, two guide rails on the fixed frame, two guide tubes at one end of the fixed frame, a flexible shaft slidably connected inside each guide tube, an upper slider fixedly connected to the end of the left flexible shaft, the upper slider slidably connected to the guide rails, a sliding window connecting block engaged with the side of the upper slider near the fixed frame, a movable glass window fixedly connected to the sliding window connecting block, a lower slider fixedly connected to the end of the right flexible shaft, the lower slider fixedly connected to the movable glass window, a motor fixedly mounted at one end of the fixed frame, a drive gear fixedly connected to the output shaft of the motor, the drive gear meshing with both flexible shafts, a stop bar fixedly connected to the fixed frame, an installation groove fixedly connected inside the stop bar, a positioning seat fixedly connected inside the installation groove, an installation block engaged outside the positioning seat, and the installation block slidably connected inside the installation groove, an elastic clip fixedly connected to the installation block, and a conductive sheet on the movable glass window, the conductive sheet slidably connected to the elastic clip.

[0005] Preferably, a pad is adhered to the fixed frame, and the pad is in contact with the movable glass window. The pad provides auxiliary support for the movable glass window, improving its accuracy during opening and closing.

[0006] Preferably, the fixed frame is provided with a decorative outer shell. Components such as guide rails, guide tubes, flexible shafts, upper sliders, lower sliders, motors, and pads are located inside the decorative outer shell, which serves both aesthetic and protective purposes.

[0007] Preferably, a fixing block is fixedly connected inside the mounting block, and guide rods are fixedly connected to both the left and right sides of the fixing block. Guide blocks are fixedly connected to the outer sides of the guide rods, and a locking block is fixedly connected to the guide blocks. The locking block passes through the positioning seat and is slidably connected to it. The locking block engages with the mounting block, and a pusher is slidably connected to the bottom of the positioning seat. The arc end of the pusher abuts against the inclined groove of the locking block. Through the interaction between the pusher and the inclined groove of the locking block, the locking block can be subjected to lateral compressive force.

[0008] Preferably, a limiting block is fixedly connected to the end of the guide rod, and the limiting block abuts against the guide block. The limiting block limits the travel of both the guide block and the locking block.

[0009] Preferably, a spring is sleeved on the outer side of the guide rod, one end of the spring is fixedly connected to the guide block, and the other end of the spring is fixedly connected to the fixing block.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5A dual-axis electric window opening and closing mechanism includes a fixed frame 1, two guide rails 2 on the fixed frame 1, and two guide tubes 3 at one end of the fixed frame 1. Each guide tube 3 has a flexible shaft 4 slidably connected inside. An upper slider 41 is fixedly connected to the end of the left flexible shaft 4, and the upper slider 41 is slidably connected to the guide rail 2. A sliding window connecting block 5 is engaged with the side of the upper slider 41 closest to the fixed frame 1, and a movable glass window 122 is fixedly connected to the sliding window connecting block 5. A lower slider 42 is fixedly connected to the end of the right flexible shaft 4, and the lower slider 42 is fixedly connected to the movable glass window 122. A motor 6 is fixedly installed at one end of the fixed frame 1. A drive gear is fixedly connected to the output shaft of the motor 6. The drive gear meshes with both flexible shafts 4. The motor 6 transmits power through the gear, enabling the extension and retraction of the two flexible shafts 4. The two flexible shafts 4, through the lower slider 42 and the upper slider 41 respectively, together with the sliding window connecting block 5, realize the opening and closing of the movable glass window 122. Since there is a space between the upper slider 41 and the sliding window connecting block 5 perpendicular to the driving direction of the flexible shaft 4, the extension and retraction of the two flexible shafts 4 can be kept consistent, and the left flexible shaft 4 is less likely to jam due to installation errors. A pad 7 is glued to the fixed frame 1, and the pad 7 contacts the movable glass window 122. The pad 7 provides auxiliary support for the movable glass window 122, improving its accuracy during opening and closing. A decorative shell 9 is provided on the fixed frame 1. The guide rail 2, guide tube 3, flexible shaft 4, upper slider 41, lower slider 42, motor 6, pad 7 and other components are located inside the decorative shell 9, which serves both aesthetic and protective purposes.

[0024] Please see Figures 4-7 A stop bar 8 is fixedly connected to the fixed frame 1. A mounting groove 10 is fixedly connected inside the stop bar 8. A positioning seat 11 is fixedly connected inside the mounting groove 10. A mounting block 12 is snapped onto the outside of the positioning seat 11 and is slidably connected inside the mounting groove 10. An elastic clip 121 is fixedly connected to the mounting block 12. A conductive sheet 21 is provided on the movable glass window 122. The conductive sheet 21 is slidably connected to the elastic clip 121. When the movable glass window 122 is closed, the conductive sheet 21 contacts the elastic clip 121 and is energized, thereby activating other functions of the movable glass window 122, such as electric heating.

[0025] Please see Figure 7A fixing block 13 is fixedly connected inside the mounting block 12. Guide rods 14 are fixedly connected to both sides of the fixing block 13. Guide blocks 15 are fixedly connected to the outer side of the guide rods 14. A locking block 16 is fixedly connected to the guide block 15. The locking block 16 passes through the positioning seat 11 and is slidably connected to the positioning seat 11. The locking block 16 is engaged with the mounting block 12. A pusher 19 is slidably connected to the bottom of the positioning seat 11. The arc end of the pusher 19 abuts against the inclined groove of the locking block 16. Through the interaction between the pusher 19 and the inclined groove of the locking block 16, the locking block 16 can be subjected to lateral compressive force. A limit block 17 is fixedly connected to the end of the guide rod 14. The limit block 17 abuts against the guide block 15. The limit block 17 limits the stroke of the guide block 15 and the locking block 16. A spring 18 is fitted onto the outer side of the guide rod 14. One end of the spring 18 is fixedly connected to the guide block 15, and the other end is fixedly connected to the fixing block 13. The spring 18 allows the reaction force to act on the locking block 16 via the guide block 15. A magnetic block 20 is fixedly connected to the push frame 19, and the magnetic block 20 is attracted to the inner wall of the positioning seat 11. The magnetic block 20 provides auxiliary fixation for the push frame 19.

[0026] The specific implementation process of this utility model is as follows: In use, the motor 6 can realize the extension and retraction of the two flexible shafts 4 through the transmission of gears. The two flexible shafts 4, together with the sliding window connecting block 5, realize the opening and closing action of the movable glass window 122 through the lower slider 42 and the upper slider 41 respectively. Since there is a space between the upper slider 41 and the sliding window connecting block 5 that is perpendicular to the driving direction of the flexible shaft 4, the two flexible shafts 4 can maintain the consistency of extension and retraction, and it is not easy for the left flexible shaft 4 to get stuck due to installation errors. Moreover, when the movable glass window 122 is closed, the movable glass window 122 will be inserted into the elastic card 121, thereby assisting in fixing the movable glass window 122 when it is closed, ensuring the accuracy of its position after closing. At the same time, the elastic card 121 is energized and other functions are activated. In addition, the locking block 16 is pushed by the pusher 19, causing the locking block 16 to be retracted by force, thereby releasing the restriction on the mounting block 12. Then the mounting block 12 and the elastic card 121 can be removed and replaced together.
