Description

Technical Field

[0001] This utility model belongs to the field of window opener technology, and in particular relates to an automatic opening and closing mechanism for high-altitude suspended windows. Background Technology

[0002] Currently, many buildings with high indoor spaces, such as office buildings, warehouses, factories, and entertainment venues, have installed awning windows for ventilation or lighting purposes. Because of their high installation position, awning windows are inaccessible by hand without ladders or other tools, and are difficult to open and close. Therefore, window openers are generally used for opening and closing.

[0003] There are many types of window openers available, broadly categorized into electric and manual types. Electric window openers are widely accepted by users due to their labor-saving and ease of operation. However, electric window openers suffer from complex structures and high costs. For example, Chinese utility model patents CN211313819U and CN215804024U disclose window openers that both use a motor-driven screw to open and close windows. Torque is transmitted between the motor and the screw via a transmission component, and both include a housing for mounting and fixing components. They also feature a hinged frame that allows the housing to rotate. Therefore, the large number of components results in excessively high manufacturing costs. Utility Model Content

[0004] The purpose of this invention is to provide an automatic opening and closing mechanism for high-altitude suspended windows, solving the problems of complex structure and high manufacturing cost of electric window openers. The technical solution adopted by this invention is as follows:

[0005] An automatic opening and closing mechanism for a high-altitude suspended window includes a through-type stepper motor, an opening and closing ball head, a connecting block, a radial joint bearing, and a bearing seat. The connecting block is connected to the window sash and has a ball cavity that rotates with the opening and closing ball head. The bearing seat is connected to the window frame. The through-type stepper motor is connected to the inner ring of the radial joint bearing through a motor seat. The outer ring of the radial joint bearing is connected to the bearing seat. The screw of the through-type stepper motor passes through the radial joint bearing and is connected to the opening and closing ball head.

[0006] Furthermore, the connecting block includes a first ball-head fixing block and a second ball-head fixing block. The first ball-head fixing block is connected to the window sash, and the second ball-head fixing block is connected to the first ball-head fixing block. Both the second ball-head fixing block and the first ball-head fixing block are provided with spherical grooves. The spherical grooves of the second ball-head fixing block and the first ball-head fixing block are combined to form the spherical cavity.

[0007] Furthermore, a connecting post is provided on one side of the opening and closing ball head, which passes through the second ball head fixing block and is connected to the screw.

[0008] Furthermore, the first ball-head fixing block is connected to the window sash via a connecting accessory.

[0009] Furthermore, one end of the motor base is a flange structure, and the other end of the motor base is a tubular structure. The flange structure and the tubular structure are coaxial, and the radial spherical bearing is sleeved on the tubular structure. The through-type stepper motor is connected to the flange structure.

[0010] Furthermore, the tubular structure has a shoulder at one end near the flange structure and an elastic retaining ring at the other end away from the flange structure. The shoulder and the elastic retaining ring abut against both ends of the radial spherical bearing.

[0011] Furthermore, it also includes a remote control, with a through-type stepper motor electrically connected to the remote control.

[0012] Furthermore, the remote control is equipped with a Type-C port, and the control line of the through-type stepper motor is equipped with a Type-C plug. The remote control and the through-type stepper motor are connected through the Type-C interface.

[0013] Furthermore, it also includes a distance sensor, which is connected to the motor mount. The distance sensor is used to measure the distance between the distance sensor and the window sash and transmits the data to the PLC. The PLC is integrated into the remote control and is electrically connected to the through-type stepper motor via a control line.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model eliminates the need for a shell or transmission components. The screw rotates adaptively with the opening angle of the window sash through the rotational cooperation of the radial joint bearing and the bearing seat. It eliminates the need for a hinge frame, reduces the number of parts to be processed, and features a simple structure, low manufacturing cost, ease of operation, and safety and reliability. It innovatively improves the connection method between components, resulting in better adaptability, convenient installation, and less likelihood of jamming. It solves the problem of opening and closing high-altitude awning windows in tall buildings.

[0016] 2. When opening the window, the through-type stepper motor is started, and the window sash opens to a certain angle. When the distance between the window sash and the distance sensor reaches the opening value set by the distance sensor, the window sash is considered to be open. The distance sensor sends a signal to control the through-type stepper motor to stop via PLC. When closing the window, the through-type stepper motor reverses. When the distance between the window sash and the distance sensor reaches the closing value set by the distance sensor, the window sash is considered to be closed. The distance sensor sends a signal to control the through-type stepper motor to stop via PLC. The PLC is a single-chip microcomputer. This application can realize automatic stopping when the window sash is fully opened or closed, which can avoid damage to components caused by excessive opening or closing of the window sash, and make the operation more convenient.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0027] The connections mentioned in this utility model are divided into fixed connections and detachable connections. Fixed connections, also known as non-detachable connections, include but are not limited to conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include but are not limited to conventional disassembly methods such as bolt connections, snap-fit ​​connections, pin connections, and hinge connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can be found to achieve this function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for a fixed connection, and a bolted connection can be chosen for a detachable connection.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0029] Example: Figure 1-8 As shown, an automatic opening and closing mechanism for a high-altitude suspended window includes a through-type stepper motor 1, an opening and closing ball head 7, a connecting block 5, a radial joint bearing 3, and a bearing seat 4. The suspended window includes a window frame 91 and a window sash 92, with the upper ends of the window frame 91 and the window sash 92 hinged together. The connecting block 5 is connected to the window sash 92, and the connecting block 5 is provided with a ball cavity that rotates with the opening and closing ball head 7. The bearing seat 4 is connected to the window frame 91. The through-type stepper motor 1 is connected to the inner ring of the radial joint bearing 3 through a motor seat 2, and the outer ring of the radial joint bearing 3 is connected to the bearing seat 4. The screw 11 of the through-type stepper motor 1 passes through the radial joint bearing 3 and is connected to the opening and closing ball head 7. The high-altitude awning is a awning window where the top of the sash is hinged to the window frame. The sash 92 rotates around the hinge axis to open and close. The connecting block 5 is connected to the lower part of the sash 92. When the window is opened, the screw 11 of the through-type stepper motor 1 extends towards the sash 92, and the opening and closing ball head 7 applies a pushing force to the connecting block 5, so the sash 92 can be pushed open. During the rotational opening process of the sash 92, the connecting block 5 moves with the sash 92, forming an arc trajectory of first descending and then rising. Since the opening and closing ball head 7 and the connecting block 5 rotate in coordination, and the inner and outer rings of the radial joint bearing 3 rotate in coordination, when the connecting block 5 descends or rises, the through-type stepper motor 1 rotates with the inner ring of the radial joint bearing 3 to adapt to the height change of the connecting block 5. That is, the direction of the screw 11 can be changed, so that the sash 92 can be opened smoothly. When the window is closed, the screw 11 of the through-type stepper motor 1 retracts, and the opening and closing ball head 7 applies a pulling force to the connecting block 5, so the sash 92 can be closed.

[0030] This utility model eliminates the need for a shell or transmission components. The screw 11 rotates adaptively with the opening angle of the window sash 92 through the rotational cooperation of the inner and outer rings of the radial joint bearing 3. It eliminates the need for a hinge frame, reduces the number of parts required, and features a simple structure, low manufacturing cost, ease of operation, and safety and reliability. It innovatively improves the connection method between components, resulting in better adaptability, convenient installation, and less likelihood of jamming. It solves the problem of opening and closing high-altitude suspended windows in tall buildings.

[0031] The connecting block 5 includes a first ball head fixing block 51 and a second ball head fixing block 52. The first ball head fixing block 51 is connected to the window sash 92, and the second ball head fixing block 52 is connected to the first ball head fixing block 51. The second ball head fixing block 52 and the first ball head fixing block 51 are clamped on both sides of the opening and closing ball head 7. Both the second ball head fixing block 52 and the first ball head fixing block 51 are provided with spherical grooves. The spherical grooves of the second ball head fixing block 52 and the first ball head fixing block 51 are combined to form the ball cavity.

[0032] A connecting post 71 is provided on one side of the opening and closing ball head 7. The connecting post 71 passes through the second ball head fixing block 52 and is connected to the screw 11.

[0033] The first ball-head fixing block 51 is connected to the window sash 92 via the connecting accessory 8.

[0034] One end of the motor base 2 is a flange structure 22, and the other end of the motor base 2 is a tubular structure 23. The flange structure 22 and the tubular structure 23 are coaxial. The radial spherical bearing 3 is sleeved on the tubular structure 23. The through-type stepper motor 1 is connected to the flange structure 22.

[0035] The tubular structure 23 has a shoulder at one end near the flange structure 22, and an elastic retaining ring 21 at the other end away from the flange structure 22. The shoulder and the elastic retaining ring 21 abut against both ends of the radial spherical bearing 3.

[0036] It also includes a remote control 13, and a through-type stepper motor 1 is electrically connected to the remote control 13.

[0037] The remote controller 13 is equipped with a Type-C port, and the control line 12 of the through stepper motor 1 is equipped with a Type-C plug. The remote controller 13 and the through stepper motor 1 are connected through the Type-C interface.

[0038] It also includes a distance sensor 6, which is connected to the motor mount 2. The distance sensor 6 measures the distance between itself and the window sash 92 and transmits the data to the PLC. The PLC is integrated into the remote controller 13 and is electrically connected to the through-type stepper motor 1 via the control line 12. When the window is opened, the through-type stepper motor 1 is started, and the window sash 92 opens to a certain angle. When the distance between the window sash 92 and the distance sensor 6 reaches the opening value set by the distance sensor 6, the window sash 92 is considered to be open, and the distance sensor 6 sends a signal to control the through-type stepper motor 1 to stop via the PLC. When the window is closed, the through-type stepper motor 1 reverses. When the distance between the window sash 92 and the distance sensor 6 reaches the closing value set by the distance sensor 6, the window sash 92 is considered to be closed, and the distance sensor 6 sends a signal to control the through-type stepper motor 1 to stop via the PLC. The PLC is a 51 microcontroller. This application can realize automatic stopping of the window sash 92 when it is fully opened or closed, which can avoid component damage caused by excessive opening or closing of the window sash 92, and make the operation more convenient.

Assemble the second ball head fixing block 52, the first ball head fixing block 51, and the opening / closing ball head 7, and fix the first ball head fixing block 51 to the window sash 92. The opening / closing ball head 7 is connected to the screw 11. If the assembly encounters non-horizontal or non-vertical issues, the radial spherical bearing 3 and the opening / closing ball head 7 can be freely adjusted to be horizontal or vertical. The outer circumference of the radial spherical bearing 3 is provided with an annular groove, and the set screw is threaded into the bearing base 4. The working end of the set screw mates with the annular groove of the radial spherical bearing 3 to fix the radial spherical bearing 3.

[0040] The remote control 13 is rechargeable and has replaceable batteries.

[0041] The above embodiments are merely illustrative examples of the present utility model and do not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of the present utility model, they are all within the scope of protection of the present utility model.
