Description

Technical Field

[0001] This utility model relates to the field of doors and windows, and in particular to a gearbox device for raising and lowering doors and windows. Background Technology

[0002] Currently, many sliding doors and windows, especially those for enclosing balconies, are relatively large and heavy, and typically use motors to drive the sliding window sashes. If the motor malfunctions or there is a power outage, the sliding window sashes cannot be controlled, causing a lot of trouble for users.

[0003] Chinese utility model patent application number 202420251151.3, entitled "A Manual and Electric Drive Device for a Lifting Window," discloses a technical solution including a hollow mounting base, a drive motor, a rotating shaft, and a manual drive component. The mounting base has first mounting holes symmetrically opened on its left and right sides. The rotating shaft passes through the mounting holes and extends horizontally through the mounting base. The drive motor is mounted on one side of the mounting base and arranged parallel to the rotating shaft. The drive motor and the rotating shaft are rotatably connected via a first actuating gear and a first transmission gear. The mounting base has second mounting holes on its upper and lower sides. The manual drive component passes through the second mounting holes and is rotatably connected to the rotating shaft via a second actuating gear and a second transmission gear. Thus, in the event of a power outage or a drive motor failure, the lifting window can be opened and closed manually using the drive component. However, this technology still has the following technical problems in use:

[0004] First, in this technical solution, the mounting base, motor, and shaft must all be installed in the same horizontal frame of the window in order for the motor to drive the shaft to rotate, and the two ends of the shaft to drive the lifting sash to rise and fall. Therefore, the size of the horizontal frame of the window is very large, which greatly obstructs the view and makes the window view poor.

[0005] Secondly, the manual drive unit and the drive motor are connected to the shaft through their respective gear structures, which makes the technology have more parts, making the structure more complex and the mounting base larger. This results in a larger horizontal window frame to accommodate the mounting base, further worsening the window's visibility.

[0006] Given the above-mentioned shortcomings of the existing technology, the applicant believes it is necessary to improve it to provide a manual-automatic transmission device for lifting doors and windows with a simple structure and better visibility. Utility Model Content

[0007] The purpose of this invention is to solve the aforementioned problems and shortcomings by providing a manual / automatic transmission device for lifting windows and doors. This device utilizes a cross-shaped arrangement of longitudinal and transverse working chambers within the housing. The worm gear and worm wheel are installed longitudinally and transversely within the housing, respectively. The two ends of the worm gear extend longitudinally out of the housing and connect to the motor and manual handle, respectively. The power output shaft of the worm wheel extends transversely out of the housing, connecting to the transmission rod that drives the window's lifting motion. In use, the motor can be longitudinally installed within the window's side frame, requiring only the transmission rod to be accommodated within the window's transverse frame. This significantly reduces the size of the window's transverse frame, thereby minimizing obstruction of the view and providing a wider field of vision. Furthermore, both the electric and manual power input shafts can directly drive the active worm gear, which in turn drives the driven worm wheel. This results in a very simple structure, further reducing the size of the window's side frame and expanding the window's field of vision.

[0008] The technical solution of this utility model is implemented as follows: a manual / automatic transmission device for lifting doors and windows, characterized in that it includes a housing, which has a longitudinal working chamber and a transverse working chamber arranged in a cross shape, and the longitudinal working chamber and the transverse working chamber are interconnected; a worm gear rotatably installed in the longitudinal working chamber, with both ends of the worm gear extending out of the sides of the housing and forming an electric power input shaft for connecting to a motor shaft and a manual power input shaft for providing power manually; a worm wheel rotatably installed in the transverse working chamber and meshing with the worm gear, with a power output shaft extending out of the side of the housing.

[0009] Furthermore, the housing is composed of a bottom shell and a top shell that are fitted together.

[0010] Furthermore, the longitudinal working chamber is composed of a left longitudinal groove on the bottom shell and a right longitudinal groove on the top shell; the transverse working chamber is composed of a left transverse groove on the bottom shell and a right transverse groove on the top shell.

[0011] Furthermore, the left longitudinal groove and the left transverse groove are interconnected; the right longitudinal groove and the right transverse groove are interconnected.

[0012] Furthermore, the bottom of the left and right longitudinal grooves is provided with bearing cavities, and bearings are respectively fitted on the electric power input shaft and the manual power input shaft at both ends of the worm gear.

[0013] Furthermore, the left transverse groove is provided with bearing grooves and bearing holes on both sides; the right transverse groove is provided with bearing grooves and bearing holes on both sides; bearings are respectively fitted on both sides of the worm gear, and the power output shaft passes through the bearing holes and appears outside the side of the housing.

[0014] Furthermore, a recessed groove is provided on the side of the housing at the position of the power output shaft.

[0015] Furthermore, the cover also has multiple countersunk recesses with screw holes.

[0016] Furthermore, the bottom shell is provided with recessed areas with screw holes at the corners, and the cover shell is provided with corresponding recessed areas.

[0017] Furthermore, the bottom shell is also provided with a fixing lug with perforations.

[0018] The beneficial effects of this utility model are:

[0019] First, the housing contains a cross-shaped arrangement of longitudinal and transverse working chambers, which are interconnected. The worm gear is positioned within the longitudinal working chamber, ensuring that both the electric power input shaft (connected to the motor shaft) and the manual power input shaft (for manual operation) are also longitudinally aligned. This allows the motor to be installed in the vertical side frame of the window during use. Simultaneously, the worm wheel is located in the transverse working chamber, with its power output shaft extending laterally through the housing and connecting to the transmission rod that drives the window sash's lifting and lowering motion. In use, the horizontal frame of the window only needs to accommodate the transmission rod, allowing for a smaller size and less obstruction of the view, resulting in excellent visibility. Furthermore, the space along the wall thickness can be utilized to accommodate the invention and the motor, further minimizing the width of the vertical side frame and reducing its obstruction of the view, providing a better user experience.

[0020] Secondly, the motor and hand crank can directly drive the active worm gear through the electric power input shaft and the manual power input shaft, respectively, without the need for other parts. This makes the structure of this utility model very simple, not only reducing manufacturing costs but also allowing the mounting base to be made smaller, further reducing the size of the vertical side frame of the window and giving users a better view.

[0021] In addition, the longitudinal working chamber and the transverse working chamber can respectively limit the movement of the worm and the worm wheel, making it less likely for the worm and the worm wheel to deviate during operation, thus making the operation more stable, with lower noise and a longer service life.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figure 1 , 2 As shown in Figures 3 and 6, this utility model provides a manual / automatic transmission device for lifting doors and windows. To achieve the purpose proposed by this utility model, it includes a housing 1, which has a longitudinal working chamber 11 and a transverse working chamber 12 arranged in a cross shape, and the longitudinal working chamber 11 and the transverse working chamber 12 are interconnected; a worm gear 2 rotatably mounted in the longitudinal working chamber 11, and the two ends of the worm gear 2 respectively extend out of the sides of the housing 1 and form an electric power input shaft 21 for connecting to a motor shaft and a manual power input shaft 22 for providing manual power; a worm wheel 3 rotatably mounted in the transverse working chamber 12 and meshing with the worm gear 2, and a power output shaft 31 extending out of the side of the housing 1 from one side of the worm wheel 3.

[0031] When using this utility model, such as Figure 7As shown, the electric power input shaft 21 and manual power input shaft 22 of the worm gear 2 are arranged longitudinally, allowing the motor 30 to be longitudinally positioned within the side frame of the window. The power output shaft 31 of the worm gear 3 is arranged laterally and connected to the transmission rod 40. The transmission rod 40 drives the gear 50 to rotate, which in turn drives the racks 60 mounted on both sides of the lifting window sash 70 to move up and down, thus opening or closing the lifting window sash 70. This design utilizes the space within the wall thickness to accommodate the motor 30, allowing for a smaller width of the window side frame. Simultaneously, the horizontal frame of the window only needs to accommodate the transmission rod 40, not the motor, thus its size can also be made smaller. With smaller side and horizontal frame dimensions, there is less obstruction to the view, resulting in a better visual experience and providing users with a more enjoyable view.

[0032] like Figure 3 , 6 As shown, for ease of assembly, the housing 1 is composed of a bottom shell 10 and a top shell 20 that are fitted together. This allows for quick assembly by first installing the worm gear 2 and worm wheel 3 inside the bottom shell 10, and then fastening the top shell 20 onto the bottom shell 10.

[0033] like Figures 2 to 6 As shown, the longitudinal working chamber 11 is composed of a right longitudinal groove 101 on the bottom shell 10 and a left longitudinal groove 201 on the cover shell 20; the transverse working chamber 12 is composed of a right transverse groove 102 on the bottom shell 10 and a left transverse groove 202 on the cover shell 20. In this way, both the bottom shell 10 and the cover shell 20 can limit the movement of the worm gear 2 and the worm wheel 3, making it less likely for the worm gear 2 and the worm wheel 3 to deviate during operation, resulting in more stable operation and lower noise.

[0034] like Figures 3 to 6 As shown, in order to enable the worm 2 and the worm wheel 3 to mesh together, the right longitudinal groove 101 and the right transverse groove 102 are interconnected; the left longitudinal groove 201 and the left transverse groove 202 are interconnected.

[0035] like Figures 3 to 6 As shown, the bottom of the right longitudinal groove 101 and the left longitudinal groove 201 are also provided with bearing cavity holes 200, and bearings 4 are respectively fitted on the electric power input shaft 21 and the manual power input shaft 22 at both ends of the worm gear 2. In this way, the bearings 4 and the bearing cavity holes 200 provide effective support for the worm gear 2 when it rotates and reduce friction, so that it can run more stably.

[0036] like Figures 3 to 6As shown, the right transverse groove 102 has bearing grooves 103 and bearing holes 104 on both sides; the left transverse groove 202 has bearing grooves 103 and bearing holes 104 on both sides; bearings 4 are fitted on both sides of the worm gear 3, and the power output shaft 31 passes through the bearing holes 104 and extends outward from the side of the housing 1. This allows the worm gear to be supported by bearings during rotation and reduces friction, resulting in more stable operation.

[0037] like Figure 1 , 2 As shown, a recessed groove 5 is also provided on the side of the housing 1 at the position of the power output shaft 31. This allows the connection between the power output shaft 31 and the transmission rod 40 to be concealed in the recessed groove 5, thereby saving space and helping to further reduce the width of the window side frame, thus further increasing the window's field of vision.

[0038] like Figure 1 , 3 As shown, the cover 20 is also provided with multiple countersunk recesses 6 with screw holes, so that when the cover 20 and the bottom shell 10 are assembled together, the screws will not protrude from the surface of the cover 20, thereby saving installation space and making the thickness of the window side frame smaller, thus saving costs.

[0039] Furthermore, to make the assembly of the cover 20 and the bottom shell 10 more convenient and secure, multiple nesting protrusions 105 are provided on the bottom shell 10, and corresponding nesting notches 205 are provided on the cover 20. In this way, during assembly, the nesting action of the nesting protrusions 105 and the nesting notches 205 can be used to quickly place the cover 20 on the bottom shell 10, and then the two can be locked together by screws.

[0040] like Figure 1 , 3 As shown, the bottom shell 10 is provided with a recessed area 7 with screw holes at the corner, and the cover shell 20 is provided with a corresponding recessed area 8. In this way, the volume of the bottom shell 10 and the cover shell 20 can be reduced by the recessed area 7 and the recessed area 8, thereby saving costs. When the housing 1 is fixed to the side frame of the window, the screw does not need to pass through the bottom shell 10 and the cover shell 20, which can greatly reduce the length of the fixing screw and allow the screw to be quickly screwed into the window frame.

[0041] like Figure 1 , 2 As shown in Figure 3, the bottom shell 10 is also provided with a fixing lug 100 with a through hole. In this way, the fixing screw can pass through the through hole on the fixing lug 100 to install the shell 1 on the side frame of the window, which is very convenient to operate.
