[0038] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0039] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0040] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0041] like Figures 1 to 5As shown, the transmission device of the utility model includes an output gear 1, an angle detection component 2 connected to the output gear 1, a driving element 3 connected to the output gear 1, a regulating component 4 arranged on the driving element 3, and a clutch component 5 arranged between the driving element 3 and the output gear 1. The driving element 3 is connected to the output gear 1 in a transmission manner to drive the output gear 1 to rotate along its own axis. The angle detection component 2 is used to obtain the rotation angle of the output gear 1; the regulating component 4 is electrically connected to the angle detection component 2, and the regulating component 4 can receive the detection data of the angle detection component 2 and send a corresponding regulating signal to the driving element 3, and the driving element 3 adjusts the output speed according to the regulating signal. The clutch component 5 is used to realize the transmission or separation between the driving element 3 and the output gear 1. The driving element 3 can select a motor, and a worm is arranged at the output end of the motor to realize the transmission.
[0042] When in use, the transmission device of the utility model is installed in the electric door and window, specifically, the output gear 1 is connected to the door and window rotating shaft, and the driving element 3 drives the output gear 1 to rotate, thereby realizing the automatic opening and closing of the electric door and window. During the automatic opening and closing of the electric door and window, the angle detection component 2 detects the rotation angle of the output gear 1 in real time and transmits the rotation angle data to the regulating component 4. When the output gear 1 rotates to a preset angle, the regulating component 4 regulates the output speed of the driving element 3 to a preset speed; specifically, when the opening and closing angle of the electric door and window is close to the maximum angle, the regulating component 4 controls the driving element 3 so that the speed of the driving element 3 gradually decreases, effectively avoiding the output gear 1 from stopping suddenly when the electric door and window reaches the maximum opening and closing angle, protecting the driving element 3, and ensuring the transmission accuracy and service life.
[0043] In addition, in the power-on state, the clutch assembly 5 ensures the transmission between the driving element 3 and the output gear 1 to realize the electric opening and closing of the electric door and window. In the power-off state, the clutch assembly 5 can disconnect the transmission between the driving element 3 and the output gear 1, effectively preventing the driving element 3 from reversing and causing damage when the user manually opens and closes the door and window. The above steps realize manual and automatic integration, which is convenient to use.
[0044] See also Figure 5 As shown, the angle detection component 2 includes a detection gear 21 meshing with the output gear 1, and a Hall sensor 22 arranged at the upper end of the detection gear 21; the Hall sensor 22 is used to sense the rotation angle of the detection gear 21, and calculate the rotation angle of the output gear 1 through the gear ratio.
[0045] Specifically, the angle detection component 2 also includes a fixed plate 23, which is arranged above the detection gear 21, and the Hall sensor 22 is fixed to the upper end of the fixed plate 23; a sensing shaft 24 extends upward from the axial part of the detection gear 21, and the upper end of the sensing shaft 24 passes through the fixed plate 23 upward, and is specifically located below the Hall sensor 22; the Hall sensor 22 detects the rotation angle of the sensing shaft 24 to obtain the rotation angle of the detection gear 21.
[0046] See also Figure 1 and Figure 2 As shown, the control component 4 includes an angle sensor 41 connected to the driving element 3, and a control board 42 connected to the angle sensor 41; in a specific application, the angle sensor 41 is used to obtain the output speed data of the driving element 3 and transmit it to the control board 42, and the control board 42 receives the rotation angle data of the output gear 1 from the angle detection component 2. The control board 42 analyzes the above two data and outputs a corresponding control signal to the driving element 3, thereby regulating the output speed of the driving element 3. Specifically, according to the different rotation angles of the output gear 1, the output speed of the driving element 3 is gradually reduced and finally stopped; it plays a buffering role to avoid the output gear 1 from stopping suddenly, causing damage to the driving element 3, and affecting the service life and transmission accuracy.
[0047] See also Figure 3 to Figure 4 As shown, the clutch assembly 5 includes a clutch shaft 51, a clutch gear 52 connected to the clutch shaft 51, a clutch deformation member 53 connected to the clutch shaft 51, and a clutch sleeve 54 sleeved on the outside of the clutch deformation member 53; wherein the clutch gear 52 is transmission-connected to the driving element 3, and meshing teeth are provided on the clutch sleeve 54 for transmission connection with the output gear 1; according to different usage states, the clutch deformation member 53 has an expansion state and a contraction state.
[0048] In the powered-on state, the clutch deformable member 53 is in an expanded state, and the clutch gear 52 rotates under the drive of the driving element 3; the clutch deformable member 53 expands outward along the radial direction of the clutch shaft 51, and the clutch deformable member 53 abuts against the inner wall of the clutch sleeve 54, and the clutch sleeve 54 rotates with the clutch gear 52 to achieve the transmission connection between the driving element 3 and the output gear 1, thereby ensuring the automatic opening and closing of the doors and windows. In the powered-off state, the clutch deformable member 53 is in a contracted state, and the clutch deformable member 53 contracts inward along the radial direction of the clutch shaft 51, and the clutch deformable member 53 cannot abut against the inner wall of the clutch sleeve 54, thereby disconnecting the transmission between the driving element 3 and the output gear 1; at this time, the user can manually open and close the doors and windows, and in this process, the driving element 3 will not be reversed and damaged under the action of external force. It can be used normally in the powered-on or powered-off state, with manual or automatic operation modes, and has a wider range of application scenarios.
[0049] In one embodiment, the clutch deformation member 53 includes a rotating ring 531 connected to the clutch shaft 51, a roller group 532 arranged around the outside of the rotating ring 531, and an elastic element 533 arranged on the outside of the roller group 532; specifically, the cross-sectional shape of the rotating ring 531 is a polygon, and when the rotating ring 531 rotates, the edges of the rotating ring 531 can abut against the roller group 532.
[0050] In the expanded state, the rotating ring 531 rotates with the clutch gear 52 and squeezes the roller set 532, driving the roller set 532 to move outward along the radial direction of the clutch shaft 51 to abut against the inner wall of the clutch sleeve 54. In the contracted state, the rotating ring 531 releases the squeezing of the roller set 532, and the elastic element 533 drives the roller set 532 to move inward along the radial direction of the clutch shaft 51, so that the roller set 532 is separated from the inner wall of the clutch sleeve 54.
[0051] Specifically, the roller assembly 532 includes a plurality of clutch rollers 534 distributed in a circumferential array on the outside of the rotating ring 531, a groove 535 is provided on the outside of the clutch roller 534, and the elastic element 533 is sleeved in the groove 535 to prevent the elastic element 533 from falling off. A plurality of spacers 536 are provided on the inside of the clutch sleeve 54 and are arranged at intervals along its axis. The spacers 536 are arranged between adjacent clutch rollers 534, and the elastic element 533 is sleeved on the outside of the spacers 536.
[0052] See also Figure 1 As shown, it also includes a lock box 6 and a rack 7; the lock box 6 is used to accommodate the angle detection component 2, the driving element 3, the regulating element, and the clutch component 5; a long strip-shaped movable hole 61 is opened on the lock box 6, and the rack 7 is meshed and connected with the output gear 1. The rack 7 is arranged in the movable hole 61 and reciprocates along the length direction of the movable hole 61. As shown in the figure, a first end point 61a and a second end point 61b are arranged at both ends of the movable hole 61 in the length direction, and a movable range of the rack 7 is arranged between the first end point 61a and the second end point 61b. When the rack 7 moves to the first end point 61a or the second end point 61b, the rack 7 will interfere with the movable hole 61, so that the output gear 1 stops rotating.
[0053] See also Figure 2 As shown, in order to ensure transmission, the transmission device of the utility model also includes a transmission component 8, and the transmission component 8 includes a plurality of transmission gears 81, through which the transmission between the angle detection component 2 and the output gear 1, and the output gear 1 and the driving element 3 is realized.
[0054] It also includes a door and window structure, including the above-mentioned transmission, and also includes a frame and doors and windows. The doors and windows are rotatably connected to the frame through the transmission. Specifically, the transmission is embedded in the frame, and the rotating part of the doors and windows is connected to the transmission, thereby realizing the rotation of the doors and windows relative to the frame to realize the opening and closing of the doors and windows.
[0055] Compared with the prior art, the transmission device and door and window structure involved in the utility model are applied to electric doors and windows, and are provided with an output gear 1, an angle detection component 2, a driving element 3, a regulating component 4 and a clutch component 5; wherein the output gear 1 is connected to the door and window, and the driving element 3 drives the output gear 1 to rotate forward and reverse to realize automatic opening and closing of the door and window; the angle detection component 2 can detect the rotation angle of the output gear 1, and the regulating component 4 regulates the output speed of the driving element 3 according to the data of the angle detection component 2, and then adjusts the rotation speed of the output gear 1 to avoid the output gear 1 from stopping suddenly and affecting the service life of the driving element 3; in addition, a clutch component 5 is provided, which ensures the transmission between the driving element 3 and the output gear 1 when the power is on, so as to realize automatic opening and closing of the door and window; when the power is off, the clutch component 5 can disconnect the transmission between the driving element 3 and the output gear 1, so as to realize manual opening and closing of the door and window.
