Detailed implementation mode

[0016] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0017] Reference is made below Figures 1-8 to describe a manual and automatic push-and-pull window opener for flat windows according to an embodiment of the present application.

[0018] Please refer to Figure 1 , Figure 2 and Figure 3 , according to some embodiments of the present application, the manual and automatic push-and-pull window opener 100 for flat windows includes: a first frame 1, a second frame 2 and a driving device 3. The first frame 1 is arranged in a closed frame shape; the second frame 2 is arranged in a closed frame shape and corresponds to the first frame 1 in a first direction, and at least one of the first frame 1 and the second frame 2 is in a shape that is recessed away from the other; the driving device 3 includes a driver 31 and a transmission assembly 32. The driver 31 is installed on one of the first frame 1 and the second frame 2, and the transmission assembly 32 is connected between the first frame 1 and the second frame 2. The driver 31 includes a hand crank 312 and a driving motor 311 that are power-coupled to the transmission assembly 32 to drive the first frame 1 and the second frame 2 to approach or move away from each other in the first direction; wherein, when the first frame 1 and the second frame 2 approach and are connected to each other, the inner circles and the outer circles of the first frame 1 and the second frame 2 are correspondingly connected, so that the first frame 1 and the second frame 2 jointly define a closed storage cavity, and the transmission assembly 32 is received in the storage cavity.

[0019] The first housing 1 and the second housing 2 provide a basic structural framework for the window opener. They can be made of materials such as metal (e.g., aluminum alloy, which has high strength and corrosion resistance), plastic (e.g., polycarbonate, which is light in weight and low in cost), etc., and play a role in carrying and protecting the internal components. The second housing 2 corresponds to the first housing 1 in the first direction, and at least one housing (which can be the first housing 1, the second housing 2, or both) is in a shape that is recessed away from the other. This recessed shape can form a spatial structure of a closed storage cavity when the two housings are close and connected. For example, the recessed shape can be a V-shaped recess, an arc-shaped recess, a trapezoidal recess, a rectangular recess, etc.

[0020] The hand crank 312 can be used by the user when there is a power outage or manual operation is required. By manually rotating the hand crank 312, power is transmitted to the transmission assembly 32; the drive motor 311, on the other hand, uses electrical energy to convert into mechanical energy and drives the transmission assembly 32 to work when powered on. The installation position of the driver 31 can be selected according to actual design requirements. For example, it can be installed on the side of the first housing 1 for convenient wiring and operation. The transmission assembly 32 is connected between the first housing 1 and the second housing 2, and its function is to transmit the power provided by the driver 31 to achieve the first housing 1 and the second housing 2 moving closer to or away from each other in the first direction. The transmission assembly 32 can be a gear transmission structure (transmitting power through the meshing of gears, with high transmission efficiency), a chain transmission structure (suitable for long-distance transmission, with stable transmission), a lead screw nut transmission structure (able to convert rotational motion into linear motion, with high precision), etc.

[0021] When the first housing 1 and the second housing 2 are close and connected to each other, their inner circles and outer circles are correspondingly connected, thus jointly defining a closed storage cavity, and the transmission assembly 32 is housed therein. This can effectively prevent the transmission components from being exposed to the external environment, prevent impurities such as dust and rainwater from adhering, protect the transmission assembly 32, and extend its service life.

[0022] According to the manual and electric integrated push-and-pull window opener 100 provided by the embodiment of the present application, by setting the first housing 1, the second housing 2, and the unique drive device 3, two drive modes of electric and manual are realized, meeting the usage requirements in different scenarios. At the same time, the design of using the first housing 1 and the second housing 2 to be close and connected to form a closed storage cavity to house the transmission assembly 32 avoids the adhesion of dust and impurities to the transmission components, ensures the transmission stability, reduces the wear and jamming of the transmission components, and thus improves the service life of the window opener. And because the transmission structure is hidden, it does not damage the overall beauty of the doors and windows. Please refer to Figure 2 and Figure 3, in some embodiments, a housing 314 is provided outside the drive motor 311 and the hand rocker 312. A through hole corresponding to the hand rocker 312 is provided on the housing 314, and a rubber plug 315 is provided in the through hole. By providing the housing 314, it plays a role in protecting the drive motor 311 and the hand rocker 312 as well as decoration. When there is a power outage, the rubber plug 315 can be removed, and a hand crank is used to connect to the hand rocker 312 through the through hole, and the hand crank is rotated to open or close the window.

[0023] Please refer to Figures 4-7 , according to some embodiments of the present application, the first frame 1 may include a plurality of first side frames 11 connected in sequence, and the second frame 2 may include a plurality of second side frames 21 corresponding to the plurality of first frames 1 one by one; the transmission assembly 32 includes a screw 321 provided on the first side frame 11. The screw 321 extends along the length direction of the first side frame 11 and is rotatably provided around its axis. A slider 323 that is in threaded cooperation with the screw 321 is provided on the screw 321. The transmission assembly 32 further includes a swing rod 324. One end of the swing rod 324 is rotatably connected to the slider 323, and the other end is rotatably connected to the second side frame 21 corresponding to the first side frame 11 where the slider 323 is located; the driver 31 is provided on the first frame 1. The driver 31 further includes a drive shaft 313 passing through the first frame 1. One end of the drive shaft 313 located in the installation cavity is power-coupled to the screw 321 to drive the screw 321 to rotate, and one end of the drive shaft 313 located outside the installation cavity is power-coupled to the output end of the drive motor 311 and the hand rocker 312.

[0024] The first frame 1 is composed of a plurality of first side frames 11 connected in sequence, and the second frame 2 includes a plurality of second side frames 21 corresponding to the plurality of first side frames 1 one by one. The side frames of the two are correspondingly arranged. The number of the first side frames 11 and the second side frames 21 is not specifically limited. For example, two, three or four first side frames 11 and the corresponding second side frames 21 can be provided. Taking four as an example, the four first side frames 11 are connected end to end to form a closed rectangular frame-shaped first frame 1, and the four second side frames 21 are also connected end to end to form a closed rectangular frame-shaped second frame 2, and the two correspond to each other.

[0025] The screw 321 can be installed on the first frame 11 through bearings to reduce the frictional resistance during rotation. The function of the screw 321 is to convert the rotational motion of the driver 31 into linear motion. The slider 323 is in threaded engagement with the screw 321. When the screw 321 rotates, the slider 323 will move along the axial direction of the screw 321. The slider 323 can be made of wear-resistant plastic or metal materials, and its threaded engagement with the screw 321 can accurately transmit the motion. The swing rod 324 can be rotatably connected through connecting parts such as pin shafts. Its function is to convert the linear motion of the slider 323 into the translational motion of the second frame 2 relative to the first frame 1, thereby realizing window opening and closing. The number of swing rods 324 can be the same as the number of screws 321 and sliders 323. For example, two screws 321, two sliders 323 and two swing rods 324 are provided, symmetrically distributed between the first frame 1 and the second frame 2 to ensure the stability and balance of the transmission.

[0026] The driver 31 is installed on the first frame 1. The drive shaft 313 included in the driver 31 passes through the first frame 1, and one end thereof located in the installation cavity is power-coupled to the screw 321. A common power-coupling method can be through a coupling connection, so as to transmit the rotational power of the drive shaft 313 to the screw 321 and drive the screw 321 to rotate; one end of the drive shaft 313 located outside the installation cavity is power-coupled to the output end of the drive motor 311 and the hand crank 312, for example, through a gear meshing or belt drive method, to realize the power transmission of two driving modes of electric and manual.

[0027] Please refer to Figure 4 and Figure 5 According to some embodiments of the present application, two adjacent first frames 11 are angularly connected. The screw 321 is provided with bevel gears 322 at the ends close to the adjacent first frames 11. The two screws 321 located on the two adjacent first frames 11 are power-coupled through the bevel gears 322; wherein, the driver 31 is arranged on one of the multiple first frames 11 and is power-coupled to the screw 321 of this first frame 11.

[0028] Two adjacent first frames 11 are angularly connected. For example, it can be a right-angle connection, an acute-angle connection or an obtuse-angle connection, etc. Commonly, in a rectangular frame, adjacent frames are at a right-angle connection. This angular connection method enables the first frame 1 to be designed according to the actual shape and requirements of the doors and windows, and has good adaptability.

[0029] The function of the bevel gear 322 is to achieve the power transmission between adjacent screws 321, transmit the rotational motion of one screw 321 to another screw 321, so that they can work together. The driver 31 is arranged on one of the plurality of first frames 11 and is power-coupled to the screw 321 of the first frame 11. For example, when the first frame 1 is a rectangular frame, the driver 31 can be installed on one of the long side frames, connected to the screw 321 on the frame through the drive shaft 313, transmit the power to the screw 321, and then transmit the power to the screw 321 on the adjacent frame through the bevel gear 322, so as to realize the synchronous rotation of multiple screws 321. This enables only one driver 31 to drive multiple screws 321 to rotate synchronously, simplifies the structure of the drive system, and reduces the cost. At the same time, this connection method can ensure the synchronism of multiple screws 321, make the window opener run more smoothly during operation, and improve the overall performance and reliability of the window opener.

[0030] Please refer to Figure 1 、 Figure 2 and Figure 4 , according to some embodiments of the present application, two screws 321 are provided on each first frame 11. The two first screws 321 on the first frame 11 are spaced apart at both ends of the first frame 11 along its extending direction. A swing rod 324 is connected to the slider 323 of each first screw 321. The thread directions of the two screws 321 on the same first frame 11 are opposite; wherein, a transmission rod 325 connected between the drive shaft 313 and the screw 321 is provided on the first frame 11 where the driver 31 is provided, and the transmission rod 325 is coaxially connected to the screw 321.

[0031] Two screw rods 321 are provided on each first frame edge 11. The two screw rods 321 are spaced apart at both ends of the frame edge along the extending direction of the first frame edge 11. Such a distribution method can make the second frame body 2 more evenly stressed during movement, avoiding skew or jamming phenomena. For example, in the rectangular first frame body 1, screw rods 321 are provided at both ends of the long side frame edge and the short side frame edge to ensure the stability of the entire second frame body 2 during translation. The thread directions of the two screw rods 321 on the same first frame edge 11 are opposite, so that when the screw rods 321 rotate, the moving directions of the two sliders 323 are opposite. For example, when one screw rod 321 rotates clockwise, the slider 323 cooperating with it moves to the left; when the other screw rod 321 with the opposite thread direction rotates clockwise, the slider 323 cooperating with it moves to the right, thereby realizing the smooth pushing and pulling of the second frame body 2 and further improving the smoothness and reliability of the window opener operation. The transmission rod 325 plays a role in transmitting power. It stably transmits the power of the drive shaft 313 to the screw rod 321. Common coaxial connection methods can be key connection, coupling connection, etc. In some examples, the drive shaft 313 is perpendicular to the transmission rod 325. A bevel gear portion is provided at one end of the drive shaft 313 located in the storage cavity. Two transmission rods 325 are provided on both sides of the drive shaft 313. One end of the transmission rod 325 close to the drive shaft 313 is meshed and connected through the bevel gear portion. The end of the transmission rod 325 far from the drive shaft 313 is keyway-connected to the screw rod 321, ensuring that there will be no slipping or misalignment during the power transmission process, enabling the driver 31 to efficiently drive the screw rod 321 to rotate.

[0032] By providing two screw rods 321 with opposite thread directions on each first frame edge 11 and cooperating with the swing rod 324 and the transmission rod 325, the second frame body 2 can be more evenly stressed during movement, greatly improving the smoothness of the window opener operation and reducing the shaking and jamming of the doors and windows during opening and closing.

[0033] Please refer to Figure 1 、 Figure 2 and Figure 4 According to some embodiments of the present application, a connecting rod 326 can be provided on the first frame edge 11 adjacent to the first frame edge 11 provided with the driver 31. The connecting rod 326 is coaxially connected between the two screw rods 321 on the corresponding first frame edge 11.

[0034] The function of the connecting rod 326 is to coaxially connect two screws 321 on the corresponding first frame 11, which can ensure stable power transmission between the screws 321. There are various connection methods between the connecting rod 326 and the screw 321. For example, through key connection, key grooves are machined on the screw 321 and the connecting rod 326, and the two are fixed with a key to achieve coaxial rotation; or a coupling connection can be adopted, which is convenient for installation and disassembly and can compensate for a certain coaxiality error at the same time. By connecting two screws 321 with the connecting rod 326, the two screws 321 on adjacent frames can rotate synchronously, further enhancing the stability and synchronism of the entire transmission system. During the operation of the window opener, problems such as uneven force and running jamming caused by the asynchronous rotation of the two screws 321 can be avoided, ensuring smooth opening and closing of the doors and windows.

[0035] Please refer to Figure 1 、 Figure 2 and Figure 4 According to some embodiments of the present application, the first frame 11 includes a first planar portion 111 and a first vertical portion 112 that are vertically connected. The second frame 21 includes a second planar portion 211 and a second vertical portion 212 that are vertically connected. The first planar portion 111 and the second planar portion 211 are perpendicular to the first direction and correspond to each other. The first vertical portion 112 and the second vertical portion 212 extend along the first direction. When the first frame 1 and the second frame 2 approach and connect to each other, the first vertical portion 112 abuts against the second planar portion 211, and the second vertical portion 212 abuts against the first planar portion 111; wherein, a first seal 113 is provided at the portion where the first planar portion 111 contacts the second vertical portion 212, and a second seal 213 is provided at the portion where the second planar portion 211 contacts the first vertical portion 112.

[0036] Both the first planar portion 111 and the second planar portion 211 are perpendicular to the first direction (i.e., the direction of door and window opening and closing) and are parallel and corresponding to each other. This structure enables the first frame 1 and the second frame 2 to form a flat surface when closed, improving the overall aesthetics and sealing performance of the doors and windows. The first vertical portion 112 and the second vertical portion 212 extend along the first direction, forming a cross-sectional structure similar to an "L" shape. When the doors and windows are closed, the first vertical portion 112 abuts against the second planar portion 211, and the second vertical portion 212 abuts against the first planar portion 111, forming an interleaved sealing interface. When the first frame 1 and the second frame 2 approach and close to each other along the first direction, the end face of the first vertical portion 112 abuts against the surface of the second planar portion 211, and at the same time, the end face of the second vertical portion 212 abuts against the surface of the first planar portion 111. This design enables the two frames to form multiple sealing barriers when closed, effectively blocking the penetration of external dust, rainwater, and air.

[0037] The first seal 113 is located at the part where the first planar portion 111 contacts the second vertical portion 212. For example, it can be embedded in the groove of the first planar portion 111. When the door or window is closed, the second vertical portion 212 presses the first seal 113 to form a seal. The second seal 213 is located at the part where the second planar portion 211 contacts the first vertical portion 112. Similarly, it can be embedded in the groove of the second planar portion 211 and realizes the seal through extrusion deformation. The seal can be made of elastic materials such as rubber (such as EPDM), silicone rubber, etc., which have good weather resistance and compression resilience to ensure the sealing effect after long-term use.

[0038] Please refer to Figures 1-6 , according to some embodiments of the present application, the screw 321 is provided on the first vertical portion 112, the other end of the swing rod 324 is rotatably connected to the corresponding second vertical portion 212, the first vertical portion 112 of the first frame 11 is located inside the inner circle of the first frame body 1, the second vertical portion 212 of the second frame 21 is located outside the outer circle of the second frame 21, and the driver 31 is provided on the first vertical portion 112.

[0039] The screw 321 is arranged on the first vertical portion 112. Such an arrangement enables the screw 321 to make full use of the space extending in the first direction of the first vertical portion 112 for layout during the relative movement of the first frame body 1 and the second frame body 2. The screw 321 can be fixed on the first vertical portion 112 through a bearing seat. The bearing seat is installed at the preset installation hole position of the first vertical portion 112 by means of bolt connection to ensure that the screw 321 can rotate flexibly around its axis and remain stable during the working process. One end of the swing rod 324 is rotatably connected to the slider 323 on the screw 321, and the other end is rotatably connected to the corresponding second vertical portion 212. The rotational connection between the swing rod 324 and the second vertical portion 212 can be realized through a pin shaft. A through hole is opened on the second vertical portion 212, the pin shaft is passed through the hole at the end of the swing rod 324 and the through hole of the second vertical portion 212, and is fixed by a circlip or a nut, so that the swing rod 324 can swing around the pin shaft, thereby converting the linear motion of the slider 323 into the translational motion of the second frame body 2.

[0040] The first vertical portion 112 of the first frame 11 is located inside the inner ring of the first housing 1, and the second vertical portion 212 of the second frame 21 is located outside the outer ring of the second housing 2. This layout of the inner ring and the outer ring enables the first housing 1 and the second housing 2 to better form a closed storage cavity when approaching and connecting to each other, and houses the transmission assembly 32 therein. At the same time, this layout is also conducive to the abutting and sealing between the first vertical portion 112 and the second planar portion 211, and between the second vertical portion 212 and the first planar portion 111, ensuring the sealing effect. The driver 31 is disposed on the first vertical portion 112. Since the first vertical portion 112 has sufficient space and structural strength, it can provide a stable installation foundation for the driver 31. The driver 31 can be fixed to the first vertical portion 112 through a bracket, and the bracket and the first vertical portion 112 are connected by welding or bolts, ensuring that the driver 31 will not loosen during operation and facilitating power connection with components such as the screw 321 and the drive shaft 313.

[0041] Please refer to Figure 8 , according to some embodiments of the present application, a guiding groove extending along the length direction of the first frame 11 may be provided on the first vertical portion 112. The cross-section of the guiding groove is arranged in a T shape. A guiding portion inserted into the guiding groove is provided on the slider 323, and at least a part of the screw 321 is located in the guiding groove.

[0042] This guiding groove with a T-shaped structure has good guiding and limiting effects, and can provide an accurate path for the movement of the slider 323, preventing the slider 323 from shifting or shaking during movement. A guiding portion inserted into the guiding groove is provided on the slider 323, and the shape of the guiding portion matches that of the guiding groove, usually also in a T shape. The guiding portion can be integrally formed with the slider 323 or fixed to the slider 323 by means of welding, bolt connection, etc. The fitting clearance between the guiding portion and the guiding groove should be controlled within a reasonable range, ensuring that the slider 323 can slide smoothly in the guiding groove and effectively restricting the lateral movement of the slider 323, improving the stability of the transmission.

[0043] At least a part of the screw 321 is located in the guiding groove. This design makes the cooperation between the screw 321 and the slider 323 more compact, and can also play a certain protective role for the screw 321, reducing the erosion of the screw 321 by external impurities, and reducing the space occupied by the transmission assembly 32, improving the space utilization rate.
