Description

Technical Field

[0001] The utility model relates to the field of window opening equipment, in particular to an automatic window opening machine. Background Art

[0002] Electric window openers operate by using a motor to drive a transmission mechanism, opening and closing the window. This mechanism typically uses a gear or chain drive to convert the motor's rotation into the window's opening and closing motion. Intelligent electric window openers, controlled by a microcomputer integrated circuit, can automatically open and close windows remotely.

[0003] In related technologies, the overall structure of the window opener is compact, and the internal structure is assembled in a small area. It relies on a single motor to drive, and its actual power and endurance cannot be guaranteed. In addition, when the user performs an emergency stop, the power is lost, and the gear train is used to reduce speed, resulting in linear force decay. The motor may momentarily jam, and the gears in the transmission chain are prone to tooth disengagement, causing structural damage and shortening the life of the window opener. Therefore, how to improve the power, endurance, and service life of the window opener is an urgent problem that needs to be solved. Utility Model Content

[0060] Embodiment

[0061] The present embodiment provides an automatic window opener, referring to Figures 1 to 12 The automatic window opener comprises a box body 1 and a driving assembly, a speed reduction chain assembly, a transmission chain assembly, an electromagnetic clutch part 5 and a fluid damping part 6.

[0062] Referring to Figure 1 The box body 1 serves as a mounting base, and the box body 1 comprises a detachable joint sealing plate 11, a cover plate 12 and an enclosing frame 13. The enclosing frame 13 is connected to the end face of the sealing plate 11, and the cover plate 12 is embedded on the side of the enclosing frame 13 away from the sealing plate 11. The sealing plate 11, the cover plate 12 and the enclosing frame 13 jointly enclose a mounting cavity. The driving assembly, the speed reduction chain assembly, the transmission chain assembly, the electromagnetic clutch part 5 and the fluid damping part 6 are arranged in the mounting cavity of the box body 1. A plurality of limiting baffles are arranged in the mounting cavity to limit the assembly of the internal structural parts.

[0063] In this embodiment, see Figure 1 and Figure 2 The drive assembly includes a first drive member 21 and a second drive member 22. The drive end of the first drive member 21 and the drive end of the second drive member 22 are connected to form the drive side of the drive assembly. The reduction chain assembly is connected to the drive side of the drive assembly. The input end of the transmission chain assembly and the reduction end of the reduction chain assembly are connected. The electromagnetic clutch component 5 is installed at the connection between the input end of the transmission chain assembly and the reduction end of the reduction chain assembly; the electromagnetic clutch component 5 is suitable for switching the input end of the transmission chain assembly and the reduction end of the reduction chain assembly to a connected or disconnected state; the fluid damping component 6 is arranged at the transmission end of the transmission chain assembly, and the fluid damping component 6 is suitable for damping the force of the reverse transmission of the transmission chain assembly.

[0064] The automatic window opener provided in this embodiment drives the deceleration chain assembly jointly by the first drive member 21 and the second drive member 22 to improve the power and endurance of the window opener; when the window is opening, the electromagnetic clutch component 5 switches to a state where the input end of the transmission chain assembly and the deceleration end of the deceleration chain assembly are connected and combined to implement the window opening operation; in an emergency or braking operation, when reverse power is supplied, the deceleration chain assembly and the transmission chain assembly run in the reverse direction with the driving action of the drive assembly, and the fluid damping component 6 directly damps the force of the reverse transmission of the transmission chain assembly to alleviate the force transmission effect of the transmission chain assembly and reduce the risk of damage to the deceleration chain assembly and the transmission chain assembly.

[0065] In a specific embodiment, see Figure 6 and Figure 7 The fluid damping component 6 includes a damping plate 61 and a damping cover 62. The damping plate 61 is drivingly connected to the transmission end of the transmission chain assembly, and the damping cover 62 is fixedly mounted within the housing 1. The damping plate 61 is spaced apart and embedded within the damping cover 62. The space between the damping plate 61 and the damping cover 62 is suitable for being filled with a fluid damping medium. In an emergency or braking operation, when reverse power is supplied, the fluid damping medium flowing through the space between the damping plate 61 and the damping cover 62 stops and buffers the rotation of the damping cover 62, thereby providing a buffering effect on the transmission chain assembly.

[0066] As an exemplary embodiment, see Figure 8 and Figure 9The damping plate 61 includes a ring platform 611 and a damping protrusion 612. The ring platform 611 and the transmission end of the transmission chain assembly are fixedly arranged, and the damping protrusion 612 is annularly fixed and distributed on the outer peripheral wall of the ring platform 611; the damping cover 62 includes a ring cover body 621 and a damping recess 622. The ring cover body 621 and the box body 1 are fixedly arranged, and the damping recess 622 is annularly distributed on the inner ring wall of the ring cover body 621; in the direction in which the ring platform 611 is away from the ring cover body 621, the damping protrusion 612 is gradually expanded, and accordingly, the damping recess 622 is also gradually expanded; an avoidance gap is provided between the damping protrusion 612 and the inner ring wall of the ring cover body 621 to allow the fluid damping medium to circulate. Among them, the ring platform 611 is a rotating body structure, the ring cover body 621 is a hollow ring structure, the ring cover body 621 has an outer edge portion bent toward the damping plate 61, and the damping recess portion 622 is specifically recessed on the inner wall surface of the outer edge portion.

[0067] In a specific embodiment, the damping protrusion 612 is at least partially annularly fixedly distributed on the outer peripheral wall surface of the annular platform 611; for example, the damping protrusion 612 is distributed 300 degrees on the outer peripheral wall surface of the annular platform 611, and a 60-degree local blank area is established on the annular platform 611 for the circulation of the fluid damping medium; this arrangement, compared with the gap space between the damping protrusion 612 and the inner annular wall surface of the annular cover body 621, can establish a larger circulation space for the fluid damping medium between the outer peripheral wall surface of the annular platform 611 and the inner annular wall surface of the annular cover body 621, so that the fluid damping medium can have a spatial area for compression and release, so that the fluid damping medium has different circulation capacities in different areas, which can improve the buffering capacity of the fluid damping component 6 during the reverse operation of the transmission chain component and enhance the damping effect.

[0068] In this embodiment, the fluid damping component 6 only damps the reverse transmission of the transmission chain assembly; in an emergency or braking operation, when reverse power is supplied, the fluid damping component 6 directly damps the force transmitted by the transmission chain assembly to alleviate the force transmission effect of the transmission chain assembly and reduce the risk of damage to the deceleration chain assembly and the transmission chain assembly.

[0069] In a specific embodiment, the extension direction of the damping protrusion 612 is parallel to the extension direction of the damping recess 622; see Figure 11The damping protrusion 612 has a first damping surface 6121 and a first transition surface 6122, and the first damping surface 6121 and the first transition surface 6122 are set by an arc-shaped curved surface transition, wherein the undulating slope of the first damping surface 6121 is smaller than the undulating slope of the first transition surface 6122, and the first damping surface 6121 and the first transition surface 6122 can be set as a plane structure; the damping recess 622 has a second damping surface 6221 and a second transition surface 6222, and the second damping surface 6221 and the second transition surface 6222 are set by an arc-shaped curved surface transition, wherein the undulating slope of the second damping surface 6221 is smaller than the undulating slope of the second transition surface 6222, and the second damping surface 6221 and the second transition surface 6222 can be set as a plane structure.

[0070] See Figure 7 and Figure 11 , the direction in which the damping plate 61 rotates clockwise relative to the damping cover 62 is set as the forward direction in which the drive assembly drives the deceleration chain assembly and the transmission chain assembly; in forward transmission, the first transition surface 6122 and the second transition surface 6222 are close to each other, and the forward rotation of the first transition surface 6122 acts on the fluid damping medium in a circumferential direction. The fluid damping medium can pass through the space between the relatively flat first damping surface 6121 and the second damping surface 6221, and its flow resistance is small, so that the transmission chain assembly transmission damping plate 61 runs smoothly in forward motion; the direction in which the damping plate 61 rotates counterclockwise relative to the damping cover 62 is set as the reverse direction in which the drive assembly drives the deceleration chain assembly and the transmission chain assembly; in reverse transmission, the first damping surface 6121 and the second damping surface 6221 are close to each other, and the fluid damping medium passes through the space between the relatively steep first damping surface 6122 and the second transition surface 6222, and its flow resistance is large, so that the transmission chain assembly transmission damping plate 61 is hindered and stopped in reverse motion.

[0071] Of course, in other embodiments, in an emergency or braking operation, when the drive component removes the forward power or reverse power, the electromagnetic clutch component 5 can be switched to a disconnected state where the input end of the transmission chain component and the deceleration end of the deceleration chain component are disconnected, and the fluid damping component 6 damps the force transmitted by the transmission chain component to alleviate the force transmission effect of the transmission chain component. A flexible buffer is provided at the transmission end of the transmission chain to reduce the risk of damage to the transmission chain component and ensure stable operation of the product.

[0072] As a preferred embodiment, see Figure 10The fluid damping component 6 also includes a limit plate 63, which is fixed relative to the box body 1. The damping plate 61 is slidably arranged at the transmission end of the transmission chain assembly, and the limit plate 63 is relatively rotatably arranged at the transmission end of the transmission chain assembly; the projection line of the extension direction of the damping protrusion 612 on the radial cross section of the ring platform 611 is offset from the center of the radial cross section of the ring platform 611; when the transmission chain assembly is reversely transmitted, the damping plate 61 is suitable for abutting and moving toward the limit plate 63 under the action of the fluid damping medium to brake the damping plate 61. With this configuration, on the one hand, in the forward transmission stage, the first transition surface 6122 circumferentially pushes the fluid damping medium between the first transition surface 6122 and the second transition surface 6222 to move along the inclined direction toward the cover body, thereby reducing the circulation resistance of the fluid damping medium. The viscosity of the fluid damping medium can drive the damping plate 61 away from the limit plate 63, thereby promoting smooth forward transmission. On the other hand, in the reverse transmission stage, the first damping surface 6121 and the second damping surface 6221 approach each other, and the space between the first transition surface 6122 and the second transition surface 6222 expands, so that the fluid damping medium close to the cover body gradually tilts into the space between the first transition surface 6122 and the second transition surface 6222 as it rotates, and contacts the damping plate 61, so that the damping plate 61 and the limit plate 63 contact each other, thereby realizing an obstruction stop for reverse transmission, which is beneficial to improving the force transmission relief performance of the transmission chain component and ensuring good power attenuation.

[0073] In the above description, the fluid damping medium is set to damping oil, and the damping oil is able to circulate in the circulation cavity formed by the damping cover 62 and the damping plate 61; wherein, a sealing film (not shown in the figure) is provided on the damping cover 62 and the damping plate 61 to seal the damping oil.

[0074] In a specific embodiment, see Figure 4 and Figure 5 The deceleration chain assembly includes a second deceleration gear 33 and a positioning shaft 34; the second deceleration gear 33 is movably sleeved on the positioning shaft 34; the transmission chain assembly includes a first bevel gear 41, the first bevel gear 41 is rotatably configured on the positioning shaft 34, and the first bevel gear 41 and the second deceleration gear 33 are arranged at intervals; the deceleration member 31 and the first deceleration gear 32 are both provided with a rotating shaft, and the rotating shaft is fixedly configured with the box body 1.

[0075] As an exemplary embodiment, see Figure 4 and Figure 5 The electromagnetic clutch component 5 includes a first electromagnetic clutch component 51 and a second electromagnetic clutch component 52. Either electromagnetic clutch component is sleeved on the positioning shaft 34. The first electromagnetic clutch component 51 is fixedly connected to the second reduction gear 33. The second electromagnetic clutch component 52 is fixedly connected to the end face of the first bevel gear component 41 away from the bevel tooth surface. The first electromagnetic clutch component 51 and the second electromagnetic clutch component 52 are arranged facing each other.

[0076] Among them, under the action of power, the first electromagnetic clutch component 51 has a first state in which it moves toward the second electromagnetic clutch component 52 to connect, so as to drive the second reduction gear 33 to slide relative to the positioning shaft 34 toward the first bevel gear component 41 to connect; under the action of power off, the first electromagnetic clutch component 51 has a second state in which it moves away from the second electromagnetic clutch component 52 to reset, so as to drive the second reduction gear 33 to move away from the first bevel gear component 41 to disconnect and separate.

[0077] The automatic window opening machine provided in this embodiment can realize the connection or disconnection of the second reduction gear 33 and the first bevel gear 41 by energizing or deenergizing the first electromagnetic clutch 51 and the second electromagnetic clutch 52, thereby achieving the purpose of switching the connection or disconnection of the input end of the transmission chain component and the reduction end of the reduction chain component. It is simple to operate and runs stably.

[0078] In this embodiment, the first driving member 21 and the second driving member 22 are both configured with a power supply module, and the power supply module is set to a rechargeable module. The driving side of the driving component superimposes the driving force of the first driving member 21 and the driving force of the second driving member 22 to ensure the power and endurance of the automatic window opening machine.

[0079] As a further embodiment, see Figure 2 The drive assembly also includes a coupling 23 and an output worm 24. One end of the coupling 23 is fixedly connected to the drive end of the first drive member 21, and the other end of the coupling 23 is fixedly connected to the drive end of the second drive member 22. The output worm 24 is installed on the drive end of the first drive member 21 or the drive end of the second drive member 22. The reduction chain assembly also includes a reduction member 31 and a first reduction gear 32. The reduction member 31 is connected to the drive side of the drive assembly. The reduction member 31 is connected to the first reduction gear 32 in transmission connection, and the first reduction gear 32 is connected to the second reduction gear 33 in transmission connection. The reduction member 31 includes a reduction worm wheel portion 311 and a reduction gear portion 312. The reduction worm wheel portion 311 is arranged for transmission with the output worm 24, and the reduction gear portion 312 is arranged for transmission with the first reduction gear 32.

[0080] Specifically, the reduction chain assembly is configured as a three-stage reduction structure, with the output worm 24 and the reduction worm gear part 311 serving as the first-stage reduction structure, the reduction gear part 312 and the first reduction gear 32 serving as the second-stage reduction structure, and the first reduction gear 32 and the second reduction gear 33 serving as the third-stage reduction structure; this arrangement enables the reduction chain assembly to be configured to transmit a reasonable rotational speed to the transmission chain assembly.

[0081] In some embodiments, the coupling 23 is configured as a universal joint, which can provide a buffer time for the drive assembly during an emergency stop. Since the impact of force during an emergency stop comes from different angles, the universal joint acts as a force unloader, and the resistance of the universal joint can be used to make the driving force exhibit a curved attenuation.

[0082] In the specific implementation, see Figure 2 、 Figure 3 and Figure 6 The transmission chain assembly also includes a second bevel gear 42, a transmission rod 43, a third bevel gear 44, a force transmission member 45, a force transmission worm gear 46, and a force transmission shaft 47. The second bevel gear 42 and the first bevel gear 41 are meshed and transmitted. One end of the transmission rod 43 is fixedly connected to the second bevel gear 42, and the other end of the transmission rod 43 is fixedly connected to the third bevel gear 44. The third bevel gear 44 and the force transmission member 45 are arranged for transmission. The force transmission member 45 and the force transmission worm gear 46 are arranged for transmission. The force transmission worm gear 46 and the force transmission shaft 47 are fixedly connected. The force transmission shaft 47 is connected to the fluid damping component 6, and the force transmission shaft 47 is arranged to rotate with the box body 1. Among them, one end of the force transmission shaft 47 is connected to the external window hinge.

[0083] In a specific embodiment, the damping plate 61 is fixedly connected to the force transmission shaft 47 , and the force transmission shaft 47 is penetrated by the damping cover 62 .

[0084] In another specific embodiment, the damping plate 61 is slidably connected to the force transmission shaft 47 , and the force transmission shaft 47 is penetrated by the damping cover 62 .

[0085] As a further embodiment, see Figure 6 The force transmission member 45 includes a rotating rod 451, a force transmission bevel gear portion 452, and a force transmission worm portion 453. The force transmission bevel gear portion 452 is fixedly sleeved on the outside of the rotating rod 451, and the force transmission worm portion 453 is fixedly sleeved on the outside of the rotating rod 451. The force transmission bevel gear portion 452 and the force transmission worm portion 453 are arranged at intervals. The force transmission bevel gear portion 452 and the third bevel gear member 44 are meshed for transmission, and the force transmission worm portion 453 and the force transmission worm wheel 46 are meshed for transmission. In this arrangement, the rotating rod 451 serves as the rotating part of the rotating connection box body 1, the force transmission bevel gear portion 452 serves as the force transmission input end, and the force transmission worm portion 453 serves as the force transmission output end. The force transmission bevel gear portion 452 and the force transmission worm portion 453 are integrated on the rotating rod 451. The overall structure of the force transmission member 45 is compact, which is conducive to the compact design of the window opener.

[0086] In some embodiments, a support assembly is provided in the box body 1, see Figure 2The support assembly includes a first support plate 71 and a second support plate 72 spaced apart, and any one of the support plates is rotatably connected to the transmission rod 43. The first support plate 71 and the second support plate 72 support the rotationally connected transmission rod 43 to support the transmission rod 43 over a long span, thereby enhancing the movement accuracy of the structure.

[0087] As a preferred embodiment, see Figure 12 The automatic window opener also includes a controller, an angle sensor, and a wind and rain sensor mounted within the housing 1. The angle sensor is adapted to detect the rotation angle of the transmission end of the transmission chain assembly, and the wind and rain sensor is adapted to detect external environmental parameters such as wind force and humidity. The controller is electrically connected to the angle sensor, the wind and rain sensor, the first drive member 21, and the second drive member 22. The controller is connected to a communication module capable of interacting with user peripherals.

[0088] During operation, the user controls the drive assembly through the controller to activate the switch. During the window opening phase, forward transmission is initiated, with the electromagnetic clutch component 5 in a closed state, and the deceleration chain assembly and transmission link assembly connected. When the angle sensor detects an actual window opening angle of 10-20°, the wind and rain sensor checks the humidity. If the humidity meets the rain threshold, reverse transmission is initiated. If the humidity detected by the wind and rain sensor does not meet the rain threshold, forward transmission continues. Subsequently, when the angle sensor detects an actual window opening angle of 80°, braking is initiated. When the user activates the closing control logic through the controller, the drive assembly executes reverse transmission to reset the window opener.

[0089] The automatic window opener provided by the present invention provides buffer damping for power attenuation or reverse power change through the fluid damping component 6, which can reduce damage to the transmission structure and is beneficial to improving the durability and operational stability of the window opener.

Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
