Description

Technical Field

[0001] The utility model relates to the field of lifting doors and windows, in particular to an electric driving device for lifting doors and windows. Background Art

[0002] At present, in the lifting doors and windows, there has emerged a technical solution in which a rotary driving mechanism (constituted by a motor or by a motor and a speed reducer together) is fixed on a sprocket seat through a plurality of screws to form a lifting device. Among them, in order to control the space occupied by the lifting device on the space of the door leaf, after a sprocket shaft is horizontally installed on the sprocket seat, the rotary driving mechanism is fixed on the side wall of the sprocket seat for the installation of the end of the sprocket shaft. And in order to maintain the stability of the installation and positioning of the rotary driving mechanism, a plurality of fixing lugs are mostly arranged on the outer peripheral wall of the rotary driving mechanism near the end of the sprocket seat, and these fixing lugs are arranged around the rotation center of the sprocket shaft. Through holes are respectively opened on each fixing lug, and the axial directions of the through holes are the same as the axial direction of the sprocket shaft. When fixing the rotary driving mechanism, the threaded end of the screw passes through the through hole and is screwed on the sprocket seat or screwed on the motor seat fixedly connected with the sprocket seat (for example: the lifting device disclosed in the patent document with the Chinese patent authorization announcement number CN221169193U and the name of "a lifting device and a lifting window for a heavy lifting window" adopts the above structure, and specific reference can be made to the specification drawings thereof Figure 3 And Figure 4 It can be undoubtedly determined).

[0003] Now, in order to control the space occupied by the lifting device, most of the fixing lugs adopt a relatively short structure, which will cause the through holes to be very close to the outer peripheral wall of the rotary driving mechanism. This will not only interfere with the insertion of the screws, but also easily affect the convenience of the relevant tools acting on the screws, and will bring inconvenience to the movement of the relevant tools. Coupled with the need to install screws in multiple directions, this will lead to relatively poor convenience in installing and positioning the rotary driving mechanism, thus resulting in the installation and positioning efficiency of the rotary driving mechanism, and this will also lead to relatively poor convenience in disassembly and maintenance.

[0004] Therefore, it is very necessary to design an electric driving device for lifting doors and windows to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above problems and deficiencies, and provide an electric driving device for lifting doors and windows.

[0025] As Figures 1 to 3 As shown, an electric drive device for a lifting and lowering door and window of the present utility model includes a sprocket seat 1 and a rotation drive mechanism 2. To achieve the invention purpose of the present utility model, at least one radial locking component 3 capable of locking them together is provided between the sprocket seat 1 and the rotation drive mechanism 2, and the radial locking component 3 is a radial locking structure capable of performing a locking operation in the radial direction of the line connecting the sprocket seat 1 and the rotation drive mechanism 2.

[0026] On this electric drive device for a lifting and lowering door and window, at least one radial locking component 3 capable of locking the sprocket seat 1 and the rotation drive mechanism 2 together is provided between them, and the radial locking component 3 is a radial locking structure capable of performing a locking operation in the radial direction of the line connecting the sprocket seat 1 and the rotation drive mechanism 2. This not only facilitates providing a reasonable installation space for the radial locking component 3, but also does not occupy the space in the thickness direction of the door and window frame, so that it is beneficial to be used on a thin door and window frame, and the applicable range of this electric drive device for a lifting and lowering door and window is relatively large; and this also facilitates providing a very suitable installation space for the radial locking component 3, which can not only facilitate the arrangement of the radial locking component 3, but also help reduce the interference with related tools. Moreover, the radial locking component 3 is beneficial for performing a locking operation in one direction, which can not only facilitate the convenience and efficiency of the installation and positioning of the rotation drive mechanism 2, but also facilitate the convenience of disassembly and maintenance.

[0027] The radial direction of the radial locking component 3 is the direction perpendicular to the line connecting the sprocket seat 1 and the rotation drive mechanism 2. The following radial directions all refer to this direction. This can reasonably utilize the relatively large space in the length direction of the door and window frame without occupying the space in the thickness direction of the door and window frame, so that it is beneficial to provide a very suitable installation space for the radial locking component 3, which can not only facilitate the arrangement of the radial locking component 3, but also help reduce the interference with related tools, and the applicability of this electric drive device for a lifting and lowering door and window is very strong.

[0028] As Figures 1 to 3As shown, the radial locking assembly 3 includes a first positioning block 31, a second positioning block 32, and a radial locking screw 33. The first positioning block 31 is disposed on the side wall of the sprocket seat 1 facing the rotary drive mechanism 2, the second positioning block 32 is disposed on the side wall of the rotary drive mechanism 2 facing the sprocket seat 1, and the threaded end of the radial locking screw 33 passes through the first positioning block 31 and is screwed onto the second positioning block 32, or passes through the second positioning block 32 and is screwed onto the first positioning block 31, or is screwed onto both the first positioning block 31 and the second positioning block 32 simultaneously. Such a radial locking assembly 3 is very simple and reliable, which not only facilitates manufacturing but also helps to achieve a stable locking effect.

[0029] During the actual manufacturing process, the radial locking assembly 3 can not only adopt the above assembly structure but also the following several assembly structures: First, the radial locking screw 33 is replaced with a radial locking bolt, and the radial locking bolt passes through the first positioning block 31 and the second positioning block 32 and then is locked; Second, the radial locking assembly 3 includes a screw rod, a locking block, and a nut. The screw rod is arranged perpendicular to the connection line between the sprocket seat 1 and the rotary drive mechanism 2, and one end of the screw rod is fixedly connected to one of the sprocket seat 1 and the rotary drive mechanism 2. The locking block is relatively disposed on the sprocket seat 1 or the rotary drive mechanism 2 where the screw rod is not installed. The screw rod passes through the locking block, and the nut is screwed onto the screw rod; Third, the radial locking screw 33 is replaced with a screw rod and two nuts. The screw rod passes through the first positioning block 31 and the second positioning block 32 simultaneously, and the two nuts are respectively screwed onto both ends of the screw rod to lock the first positioning block 31 and the second positioning block 32 together through the two nuts. Here only several radial locking structures that can achieve the locking operation in the radial direction of the connection line between the sprocket seat 1 and the rotary drive mechanism 2 are introduced. In actual manufacturing, it is not limited to the above several types, and other radial locking structures that can achieve the locking operation in the radial direction of the connection line between the sprocket seat 1 and the rotary drive mechanism 2 can also be adopted.

[0030] As Figure 3 And Figure 7 As shown, the first positioning block 31 and / or the second positioning block 32 is / are C-shaped blocks. The inner hole of the C-shaped block constitutes a hole for the threaded end of the radial locking screw 33 to pass through or be screwed. This can not only reduce the use of materials but also eliminate the adverse effects brought by small machining errors, and can reduce the adverse effects on the first positioning block 31, the second positioning block 32, and the radial locking screw 33 under large impacts, thereby helping to further improve the applicability of the electric drive device for lifting and lowering doors and windows.

[0031] As Figure 2 And Figure 3As shown, the nut end of the radial locking screw 33 is arranged horizontally forward. This not only facilitates observation but also enables relevant tools to act on the radial locking screw 33, thereby helping to further improve the convenience of installation and disassembly.

[0032] As Figures 1 to 4 , Figure 7 shown, there are three radial locking assemblies 3, and the three radial locking assemblies 3 are arranged around the power output shaft of the rotary drive mechanism 2. This can form a relatively comprehensive locking effect in the circumferential direction of the outer periphery of the power output shaft of the rotary drive mechanism 2, which not only helps to make the connection between the rotary drive mechanism 2 and the sprocket seat 1 more stable and reliable but also ensures more stable and reliable power transmission, thereby contributing to further improving the reliability and applicability of the electric drive device for lifting doors and windows.

[0033] As Figures 1 to 3 , Figure 7 shown, a sprocket shaft 4 is provided on the sprocket seat 1, one end of the sprocket shaft 4 passes through between the sprocket seat 1 and the rotary drive mechanism 2, and the sprocket shaft 4 is drivingly connected to the power output shaft 21 of the rotary drive mechanism 2. Having one end of the sprocket shaft 4 pass through between the sprocket seat 1 and the rotary drive mechanism 2 not only facilitates observation and maintenance but also enables the sprocket shaft 4 to be drivingly connected to the power output shaft 21, thereby helping to further improve the convenience of assembly.

[0034] As Figure 1 , Figure 2 , Figure 5 and Figure 7 shown, a convex block portion 211 is provided on the outer circumferential surface of the power output shaft 21, a fitting hole 41 is opened in the middle of the end face of one end of the sprocket shaft 4, a clamping groove 42 extending to its hole opening is opened on the hole wall of the fitting hole 41, the power output shaft 21 is fitted in the fitting hole 41, and the convex block portion 211 is fitted in the clamping groove 42. This can form a more stable and reliable driving connection between the sprocket shaft 4 and the power output shaft 21, thereby contributing to further improving the reliability of the electric drive device for lifting doors and windows.

[0035] As Figure 5 shown, two circles of sprocket teeth 43 are provided on the outer circumferential surface of the sprocket shaft 4. This can help to form a double-chain lifting effect, thereby facilitating the lifting of doors and windows with a greater weight, and further contributing to improving the reliability and applicability of the electric drive device for lifting doors and windows.

[0036] As Figure 3 , Figure 4 and Figure 6As shown, the sprocket seat 1 includes a U-shaped bracket 11, two arc-shaped brackets 12, and two locking plates 13. An arc-shaped card slot 111 penetrating the top surfaces at both ends is provided on the top surface of the U-shaped bracket 11. Both ends of the sprocket shaft 4 are rotatably lapped on the arc-shaped card slots 111 at both ends of the U-shaped bracket 11. The two arc-shaped brackets 12 are respectively arranged on the top surfaces at both ends of the U-shaped bracket 11, and the two arc-shaped brackets 12 can respectively be rotatably clamped to both ends of the sprocket shaft 4. The two locking plates 13 are respectively fixed to both ends of the U-shaped bracket 11, and the upper ends of the two locking plates 13 are fixedly connected to the corresponding arc-shaped brackets 12. The rotary drive mechanism 2 is connected to one of the locking plates 13 through a radial locking assembly 3. This can not only facilitate the installation of the sprocket shaft 4 but also help to stably and reliably limit the sprocket shaft 4, thereby contributing to further improving the reliability and applicability of the electric drive device for the lifting doors and windows.

[0037] As Figure 4 shown, in the actual manufacturing process, the two ends of the arc-shaped bracket 12 can be respectively fixed to the U-shaped bracket 11 by screws, and the upper and lower ends of the locking plate 13 are respectively fixed to the arc-shaped bracket 12 and the U-shaped bracket 11 by screws, so as to meet the requirements of stable installation.

[0038] As Figure 3 With Figure 4 shown, bearings 44 are respectively sleeved on both ends of the sprocket shaft 4, and the two bearings 44 are respectively embedded in the arc-shaped card slots 111 at both ends of the U-shaped bracket 11, and the two arc-shaped brackets 12 are respectively clamped on the corresponding bearings 44. This can not only stably limit the sprocket shaft 4 but also make the rotation of the sprocket shaft 4 more stable and accurate, thereby contributing to further improving the reliability of the electric drive device for the lifting doors and windows.

[0039] As Figures 3 to 6 shown, relief notches 112 are respectively provided at both ends in the width direction of the middle part of the U-shaped bracket 11. Two sprocket teeth 43 are located inside the U-shaped bracket 11, and a chain (not shown in the figure) is wound around the sprocket teeth 43, and both ends of the chain respectively pass through the two relief notches 112. By providing such two relief notches 112, it is beneficial to make the U-shaped bracket 11 adopt a wide-body structure. This can not only enable the sprocket seat 1 to reliably support the sprocket shaft 4 but also avoid the interference of the chain by the U-shaped bracket 11, thereby being beneficial to achieving a very stable and reliable lifting effect.

[0040] As Figure 3 With Figure 7As shown, in the actual manufacturing process, the rotary drive mechanism 2 can adopt the following two structures: First, the rotary drive mechanism 2 is a drive motor. Such a rotary drive mechanism 2 is very simple and has good applicability. Second, the rotary drive mechanism 2 includes a drive motor 22 and a speed reducer 23. The housing of the speed reducer 23 is fixedly connected to the housing of the drive motor 22, and the power input shaft of the speed reducer 23 is drivingly connected to the drive motor 22. The speed reducer 23 is connected to the sprocket seat 1 through a radial locking assembly 3. The power output shaft of the speed reducer 23 constitutes the above-mentioned power output shaft 21, which can output more stable power and has higher reliability and applicability.

[0041] The installation and use of the electric drive device for the lifting doors and windows are the same as the conventional installation and use methods. The sprocket seat 1 is fixed inside the door and window frame, and the rotary drive mechanism 2 is horizontally arranged inside the door and window frame. The chain is also wound around the sprocket teeth 43, and the door and window sash is connected to the chain. In this way, the door and window sash can be driven to move up and down by the electric drive device for the lifting doors and windows.

[0042] During actual use, two electric drive devices for the lifting doors and windows can be used to drive the door and window sash to move up and down. The two electric drive devices for the lifting doors and windows are arranged side by side left and right to drive the left and right ends of the door and window sash, which can make the lifting of the door and window sash more stable.
