Description

Technical Field

[0001] This invention belongs to the field of building door and window technology, and relates to automatic control technology for doors and windows, and in particular to a self-locking device and method for inclined windows based on a parallelogram mechanism. Background Technology

[0002] Slanted window mechanisms, also known as tilted window mechanisms, are a common type of window in the field of building doors and windows. They are widely used in various civil and industrial buildings such as residential, office, and commercial buildings, and are especially suitable for scenarios that require ventilation and lighting while also maximizing space utilization. A typical slanted window mechanism consists of a fixed frame and a slanted window sash. The slanted window sash is connected to the fixed frame by a hinge and can rotate around an imaginary horizontal tilt axis on the bottom side of the window. When the window sash rotates to the point where an opening is formed between the top of the sash and the fixed frame, it is in the typical working state of the slanted window – the tilted position. At this time, indoor and outdoor air can circulate while preventing rainwater from directly entering the room.

[0003] However, in practical applications, existing self-locking systems for inclined windows generally suffer from problems such as inadequate sealing and uneven stress distribution, directly affecting the comfort, energy efficiency, and safety of buildings. Specifically, the design of existing wind pressure self-locking systems for inclined windows, when the window sash is closed, is prone to improper control of the window sash tilt angle, leading to a loose seal between the window sash and the fixed frame. At the same time, the uneven stress distribution of the window sash as a whole can cause air leakage, water leakage, and other sealing failures. This not only affects the comfort of indoor living and use but may also lead to moisture damage to the window frame and walls in the long run, reducing the building's energy efficiency. On the other hand, the multi-point locking system used in traditional inclined window mechanisms is not safe enough in the face of extreme weather such as strong winds, making it difficult to meet the needs of high-rise buildings or windy areas, and thus has obvious application limitations. Summary of the Invention

[0004] In view of the technical problems existing in the prior art, the present invention provides a self-locking device and method for inclined windows based on a parallelogram mechanism, so as to solve the technical problems of poor sealing and uneven force distribution that are prone to occur in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: This invention provides a self-locking device for a slanted window based on a parallelogram mechanism, comprising a parallelogram mechanism, a self-locking system motor, and an integrated sensor; The parallelogram mechanism is disposed between the fixed frame of the slanted window mechanism and the slanted window sash, and is used to drive the slanted window sash to open or close; the self-locking system motor is disposed on the fixed frame, and the output end of the self-locking system motor is connected to the parallelogram mechanism. The integrated sensor is installed on the upper outer side of the fixed frame to collect wind speed data and raindrop information at the upper end of the fixed frame, and to generate a window opening control command based on the collected wind speed data and raindrop information at the upper end of the fixed frame. The self-locking system motor is used to receive and respond to the window opening control command, drive the parallelogram mechanism to move, and realize the switching of the opening and closing state of the slanted window sash.

[0006] Furthermore, the parallelogram mechanism includes a first link, a second link, a third link, and a fourth link; The first rod, the second rod, the third rod, and the fourth rod are sequentially hinged together to form a parallelogram structure; wherein, the first rod is attached to the side of the fixed frame, and the second rod is attached to the side of the slanted window sash. The third member is disposed at the upper end of the second member, and the third member is parallel to the first member; the fourth member is disposed at the upper end of the first member, and the fourth member is parallel to the second member. The output end of the self-locking system motor is connected to the hinge point of the second rod and the third rod.

[0007] Furthermore, the length ratio of the first rod, the second rod, the third rod, and the fourth rod is 1:1:1:1.

[0008] Furthermore, the self-locking system motor includes an electric winch, a steel wire rope, a motor housing, and a winch mounting base; The electric winch is mounted inside the motor housing via the winch mounting base, and the motor housing is fixed to the fixed frame; one end of the wire rope is wound around the output end of the electric winch, and the other end of the wire rope is connected to the hinge point of the second rod and the third rod.

[0009] Furthermore, the integrated sensor includes a wind speed sensor, a wind speed sensing signal processing circuit, a raindrop sensor, a raindrop sensing signal processing circuit, and a signal fusion module; The wind speed sensor is used to collect and send wind speed data at the upper end of the fixed frame to the wind speed sensing signal processing circuit; the wind speed sensing signal processing circuit is used to compare the wind speed data at the upper end of the fixed frame with a preset wind speed threshold to obtain wind speed monitoring results. The raindrop sensor is used to collect and send raindrop information from the upper end of the fixed frame to the raindrop sensing signal processing circuit; the raindrop sensing signal processing circuit is used to compare the raindrop information from the upper end of the fixed frame with a preset raindrop threshold to obtain raindrop monitoring results. The signal fusion module is used to generate and send window opening control commands to the self-locking system motor based on wind speed monitoring results and raindrop monitoring results.

[0010] Furthermore, the preset wind speed threshold is 3.4 m / s, and the preset raindrop threshold is 0.

[0011] Furthermore, the slanted window sash is installed within the fixed frame, and the bottom end of the slanted window sash is hinged to the bottom end of the fixed frame.

[0012] Furthermore, the parallelogram mechanism also includes a first hinge pin, a second hinge pin, a third hinge pin, and a fourth hinge pin. The first hinge pin is disposed between the first rod and the second rod to realize the hinged connection between the first rod and the second rod; The second hinge pin is disposed between the second rod and the third rod to achieve a hinged connection between the second rod and the third rod; wherein, the second hinge pin is connected to the output end of the self-locking system motor; The third hinge pin is disposed between the third member and the fourth member to realize the hinged connection between the third member and the fourth member; The fourth hinge pin is disposed between the fourth member and the first member, and is used to realize the hinged connection between the fourth member and the first member.

[0013] The present invention also provides a method for self-locking of a slanted window based on a parallelogram mechanism, utilizing the aforementioned slanted window self-locking device based on a parallelogram mechanism; Self-locking methods for slanted windows include: The wind speed data and raindrop information at the upper end of the fixed frame are collected using integrated sensors, and a window opening control command is generated based on the collected wind speed data and raindrop information at the upper end of the fixed frame. The self-locking system motor receives and responds to the window opening control command, and drives the parallelogram mechanism to operate according to the preset window opening rules, thereby switching the opening and closing state of the slanted window sash.

[0014] Furthermore, the preset window opening rules are as follows: If the wind speed monitoring result is no wind speed and the raindrop monitoring result is no rain, then the self-locking system motor drives the parallelogram mechanism to operate, so that the slanted window sash is fully open. If the wind speed monitoring result shows that the wind speed at the upper end of the fixed frame is less than the preset wind speed threshold, and the raindrop monitoring result shows that there is no rain, then the self-locking system motor drives the parallelogram mechanism to move, so that the opening and closing state of the slanted window sash is in the preset slightly open state. If the wind speed monitoring result is that the wind speed at the upper end of the fixed frame is greater than or equal to the preset wind speed threshold, or if the raindrop monitoring result is that it is raining, the parallelogram mechanism is driven by the self-locking system motor to make the opening and closing state of the slanted window sash completely closed.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides a self-locking device for slanted windows based on a parallelogram mechanism. By placing the parallelogram mechanism between the fixed frame and the slanted window sash, and utilizing the core characteristic of the parallel and synchronous movement trajectories of the endpoints of each link in the parallelogram mechanism during movement, combined with the linkage design of the self-locking system motor and the parallelogram mechanism, uniform force and tight sealing of the slanted window sash are achieved. Simultaneously, when the self-locking system motor drives the parallelogram mechanism, each locking point of the slanted window sash can synchronously and evenly press against the locking seat on the fixed frame, effectively avoiding the problem of loose sealing surfaces caused by uneven force in traditional mechanisms. This eliminates air leakage, water leakage, and other sealing failures, improving indoor comfort and enhancing building energy efficiency. Furthermore, by installing an integrated sensor on the upper outer side of the fixed frame, it can... The system collects wind speed and raindrop information in real time and generates corresponding window opening control commands. These commands are transmitted to the self-locking system motor, which drives the parallelogram mechanism to precisely switch between the opening and closing states of the slanted window sash. In extreme weather conditions such as strong winds, it can quickly respond and drive the window sash to lock. Combined with the structural stability of the parallelogram mechanism when locked, it significantly improves the wind resistance and safety of the slanted window mechanism compared to traditional multi-point locking systems, making it suitable for high-rise buildings and windy areas. Furthermore, the structural design of the parallelogram mechanism allows the self-locking system motor to output only a small driving force to achieve a strong compression and seal of the entire window sash through the mechanism transmission, balancing ease of operation and sealing reliability, and comprehensively improving the practicality, energy efficiency, and safety of the slanted window mechanism.

[0016] Furthermore, the corresponding attachment design of the first rod to the fixed frame and the second rod to the window sash allows the driving force of the mechanism to be directly and evenly transmitted to the side of the window sash. Combined with the parallel arrangement of the third and fourth rods, this effectively avoids problems such as force offset and jamming during transmission. At the same time, connecting the output end of the self-locking system motor to the hinge point of the second and third rods maximizes the transmission of motor driving force, effectively reduces the motor drive load, and achieves the design goal of using a small driving force to drive the window sash to press firmly. This also ensures that the opening and closing process of the window sash is smooth and stable, avoiding uneven contact of the window sash sealing surface due to poor transmission, and effectively optimizing the sealing effect.

[0017] Furthermore, by setting the length ratio of each member of the parallelogram mechanism to 1:1:1:1, the size specifications of the inclined window fixing frame and the window sash can be precisely matched, so that the movement trajectory of the parallelogram mechanism is perfectly adapted to the tilting opening and closing trajectory of the inclined window sash. This ensures that the sealing surface of the window sash can always remain parallel and aligned with the fixing frame throughout the entire movement process, thus fundamentally solving the problem of poor sealing caused by improper control of the window sash tilt angle in existing technologies. Secondly, the reasonable length ratio of the members can further optimize the force distribution of the mechanism, so that the clamping force of each locking point of the window sash is uniform and consistent, avoiding the phenomenon of excessive local clamping force leading to window sash deformation or insufficient local clamping force leading to sealing gaps.

[0018] Furthermore, the electric winch is installed inside the motor housing via a winch mounting bracket, and the motor housing is fixed to the fixed frame. This not only secures the motor but also protects the electric winch, wire rope, and other core transmission components from external environmental factors such as wind, rain, and dust, thus extending the motor's service life. Secondly, by utilizing the flexible transmission characteristics of the wire rope, it can adapt to the dynamic force angle changes of the parallelogram mechanism, ensuring that the driving force is stably transmitted during the mechanism's movement and avoiding the problems of force impact and transmission breakage caused by rigid transmission.

[0019] Furthermore, the integrated sensor design enables it to respond to environmental changes in real time and accurately, providing reliable command support for the self-locking system motor. This ensures that the slanted window can automatically adjust its opening and closing status according to actual wind and rain conditions, improving the device's intelligence level and ease of use.

[0020] The slanted window self-locking method based on a parallelogram mechanism provided by this invention possesses all the advantages of the aforementioned slanted window self-locking device based on a parallelogram mechanism. Attached Figure Description

Detailed Implementation

[0024] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] This invention provides a self-locking device for a slanted window based on a parallelogram mechanism, comprising a parallelogram mechanism 1, a self-locking system motor 2, and an integrated sensor 3. The parallelogram mechanism 1 is disposed between the fixed frame 100 and the slanted window sash 200 of the slanted window mechanism, and is used to drive the slanted window sash 200 to open or close. The self-locking system motor 2 is disposed on the fixed frame 100, and its output end is connected to the parallelogram mechanism 1. The integrated sensor 3 is installed on the upper outer side of the fixed frame 100, and is used to collect wind speed data and raindrop information at the upper end of the fixed frame 100, and generate a window opening control command based on the collected wind speed data and raindrop information at the upper end of the fixed frame 100. The self-locking system motor 2 is used to receive and respond to the window opening control command, drive the parallelogram mechanism 1 to move, and realize the switching of the opening and closing state of the slanted window sash 200.

[0026] In the above embodiments, by introducing a self-locking device for inclined windows composed of a parallelogram mechanism, a self-locking system motor, and integrated sensors, the technical problems of poor sealing, uneven force distribution, and insufficient safety under extreme weather conditions in traditional inclined window mechanisms are effectively solved. This achieves a strong and uniform seal with minimal operating force, while also possessing environmental adaptability, effectively improving the energy efficiency, comfort, and safety reliability of the inclined window system. The parallelogram mechanism has the characteristic of maintaining the posture of its components during movement. When applied to the drive of the inclined window sash, it ensures that the sash moves or tilts along a predetermined trajectory during opening and closing, avoiding misalignment of the sealing surface due to rotational angle deviation. More importantly, during locking, the parallelogram mechanism can evenly transmit the driving force applied by the self-locking system motor to multiple locking points on the window sash, achieving synchronous and equal pressure of each locking point onto the corresponding locking seat on the fixed frame, thereby forming a uniform overall sealing pressure distribution and significantly improving airtightness and watertightness.

[0027] Secondly, by installing an integrated sensor on the upper outer side of the fixed frame to collect wind speed and raindrop information in real time, the device can intelligently judge changes in the external environment and generate corresponding window opening control commands. This enables the device to automatically close and lock the window before wind and rain arrive, which not only improves the convenience and safety of use, but also optimizes the mechanism design by utilizing the direction of the external force of wind pressure itself. That is, under the action of wind pressure, the force of the mechanism tends to further compress and lock, forming a positive feedback mechanism that locks tighter the more wind blows, enhancing the stability and wind pressure resistance in high-rise or windy areas.

[0028] The following specific embodiments further explain the self-locking device for inclined windows based on a parallelogram mechanism provided by the present invention: Example As attached Figure 1As shown, this embodiment provides a self-locking device for a slanted window based on a parallelogram mechanism, used for controlling the opening and closing of the slanted window sash in the slanted window mechanism; wherein, the self-locking device for a slanted window based on a parallelogram mechanism can limit the maximum tilt opening angle of the slanted window sash in the slanted window mechanism, and can control the slanted window sash to close automatically.

[0029] It should be noted that the inclined window mechanism includes a fixed frame 100 and an inclined window sash 200. The fixed frame 100 is installed at a preset window in the main structure of the building, and the inclined window sash 200 is installed inside the fixed frame 100. The bottom end of the inclined window sash 200 is hinged to the bottom end of the fixed frame 100, and the inclined window sash 200 can be opened or closed around a preset horizontal inclined axis.

[0030] As attached Figure 1-7 As shown, the inclined window self-locking device based on the parallelogram mechanism includes a parallelogram mechanism 1, a self-locking system motor 2, and an integrated sensor 3.

[0031] The parallelogram mechanism 1 is disposed between the fixed frame 100 of the inclined window mechanism and the inclined window sash 200, and is used to drive the inclined window sash 200 to open or close.

[0032] The self-locking system motor 2 is mounted on the fixed frame 100, and the output end of the self-locking system motor 2 is connected to the parallelogram mechanism 1. The self-locking system motor 2 is used to receive and respond to the window opening control command sent by the integrated sensor 3, drive the parallelogram mechanism 1 to move, and realize the switching of the opening and closing state of the slanted window sash 200.

[0033] The integrated sensor 3 is installed on the upper outer side of the fixed frame 100 to collect wind speed data and raindrop information at the upper end of the fixed frame 100, and to generate a window opening control command based on the collected wind speed data and raindrop information at the upper end of the fixed frame 100.

[0034] In this embodiment, the parallelogram mechanism 1 includes a first rod 11, a second rod 12, a third rod 13, a fourth rod 14, a first hinge pin 15, a second hinge pin 16, a third hinge pin 17, and a fourth hinge pin 18; the first rod 11, the second rod 12, the third rod 13, and the fourth rod 14 are sequentially hinged together to form a parallelogram structure.

[0035] Specifically, the first rod 11 is attached to the side of the fixed frame 100, the second rod 12 is attached to the side of the slanted window sash 200; the third rod 13 is disposed above the second rod 12, and the third rod 13 is parallel to the first rod 11; the fourth rod 14 is disposed above the first rod 11, and the fourth rod 14 is parallel to the second rod 12.

[0036] It should be noted that, during the opening or closing of the slanted window sash 200, the second rod 12 can rotate synchronously with the slanted window sash 200; the third rod 13 and the fourth rod 14 do not need to be attached to the fixed frame 100 slanted window sash 200; the length of the first rod 11 is equal to the length of the fourth rod 14, and the length of the second rod 12 is equal to the length of the third rod 13.

[0037] Preferably, the length ratio of the first rod 11, the second rod 12, the third rod 13, and the fourth rod 14 is 1:1:1:1. By designing the length ratio of the first rod 11, the second rod 12, the third rod 13, and the fourth rod 14 to 1:1:1:1, it is ensured that the window sash 3 can be driven to move with a small stroke and a large torque when the user operates it. At the same time, the self-amplifying effect of the parallelogram mechanism 1 is utilized to make the locking of the slanted window sash 200 more secure under wind pressure.

[0038] The first hinge pin 15 is disposed between the first rod 11 and the second rod 12 to achieve a hinged connection between the first rod 11 and the second rod 12; the second hinge pin 16 is disposed between the second rod 12 and the third rod 13 to achieve a hinged connection between the second rod 12 and the third rod 13; the third hinge pin 17 is disposed between the third rod 13 and the fourth rod 14 to achieve a hinged connection between the third rod 13 and the fourth rod 14; the fourth hinge pin 18 is disposed between the fourth rod 14 and the first rod 11 to achieve a hinged connection between the fourth rod 14 and the first rod 11. It should be noted that the axial directions of the first hinge pin 15, the second hinge pin 16, the third hinge pin 17, and the fourth hinge pin 18 are all parallel to each other and perpendicular to the plane of the parallelogram mechanism 1.

[0039] In this embodiment, the output end of the self-locking system motor 2 is connected to the hinge point of the second rod 12 and the third rod 13, and is used to drive the slanted window sash 2 to rotate by driving the hinge point of the second rod 12 and the third rod 13, thereby realizing the switching of the opening and closing state of the slanted window sash 200; wherein, the output end of the self-locking system motor 2 is connected to the second hinge pin 16 in the parallelogram mechanism 1.

[0040] The self-locking system motor 2 includes an electric winch 21, a wire rope 22, a motor housing 23, and a winch mounting base 24. The electric winch 21 is installed inside the motor housing 23 via the winch mounting base 24, and the motor housing 23 is fixed to the fixed frame 100. One end of the wire rope 22 is wound around the output end of the electric winch 21, and the other end of the wire rope 22 is connected to the hinge point of the second rod 12 and the third rod 13. The electric winch 21 is connected and fixed to the electric winch mounting hole on the winch mounting base 24 by fixing bolts. The winch mounting base 24 is fixedly connected to the motor housing 23 by winch mounting base fixing bolts. The motor housing 23 is fixed to the fixed frame 200 by bolts through the housing mounting hole, ensuring that the self-locking system motor 2 is installed stably and does not shift during operation.

[0041] The electric winch 21 includes a winch motor 211, a gearbox 212, and a rope guide 213. The winch motor 211 is connected to the gearbox 212 for transmission, and the rope guide 213 is mounted on the output shaft of the gearbox 212. The fixed end of the wire rope 22 is wound around the outside of the rope guide 213, and the free end of the wire rope 22 passes through the outside of the motor housing 23 and is connected to the second hinge pin 16. The rope guide 213 provides winding space for the wire rope 22 and guides the winding and unwinding direction of the wire rope 22, preventing the wire rope 22 from becoming tangled.

[0042] In this embodiment, the integrated sensor 3 includes a wind speed sensor 31, a wind speed sensing signal processing circuit 32, a raindrop sensor 33, a raindrop sensing signal processing circuit 34, and a signal fusion module 35. The wind speed sensor 31 is electrically connected to the wind speed sensing signal processing circuit 32, the raindrop sensor 33 is electrically connected to the raindrop sensing signal processing circuit 34, and both the wind speed sensing signal processing circuit 32 and the raindrop sensing signal processing circuit 34 are electrically connected to the signal fusion module 35. The signal fusion module 35 is signal-connected to the self-locking system motor 2, and the output terminal of the signal fusion module 35 is connected to the control terminal of the winch motor 211.

[0043] The wind speed sensor 31 is used to collect and send wind speed data at the upper end of the fixed frame 100 to the wind speed sensing signal processing circuit 32; the wind speed sensing signal processing circuit 32 is used to compare the wind speed data at the upper end of the fixed frame 100 with a preset wind speed threshold to obtain a wind speed monitoring result; wherein, the wind speed monitoring result includes no wind speed, the wind speed at the upper end of the fixed frame 100 being less than the preset wind speed threshold, and the wind speed at the upper end of the fixed frame 100 being greater than or equal to the preset wind speed threshold; preferably, the preset wind speed threshold is 3.4 m / s; in this case, no wind speed means that the wind speed at the upper end of the fixed frame 100 is 0 m / s; the wind speed at the upper end of the fixed frame 100 being less than the preset wind speed threshold means that the wind speed at the upper end of the fixed frame 100 is 3.4 m / s, and the wind speed at the upper end of the fixed frame 100 is greater than or equal to 3.4 m / s.

[0044] The raindrop sensor 33 is used to collect and send raindrop information from the upper end of the fixed frame 100 to the raindrop sensing signal processing circuit 34; the raindrop sensing signal processing circuit 34 is used to compare the raindrop information from the upper end of the fixed frame 100 with a preset raindrop threshold to obtain a raindrop monitoring result; wherein, the raindrop monitoring result includes no rain and rain; preferably, the preset raindrop threshold is 0; at this time, no rain means that the amount of raindrops at the upper end of the fixed frame 100 is 0, and rain means that the amount of raindrops at the upper end of the fixed frame 100 is greater than 0.

[0045] The signal fusion module 35 is used to generate and send window opening control commands to the self-locking system motor 2 based on the wind speed monitoring results and raindrop monitoring results.

[0046] Self-locking method and working principle of slanted windows: Based on the parallelogram mechanism-based self-locking device for inclined windows provided in this embodiment, this embodiment also provides a method for self-locking inclined windows based on a parallelogram mechanism, including the following steps: The integrated sensor 3 collects wind speed data and raindrop information at the upper end of the fixed frame 100, and generates a window opening control command based on the collected wind speed data and raindrop information at the upper end of the fixed frame 100; the self-locking system motor 2 receives and responds to the window opening control command, and drives the parallelogram mechanism 1 to move according to the preset window opening rules, thereby switching the opening and closing state of the slanted window sash 200, as shown in the attached figure. Figure 8 As shown.

[0047] In this embodiment, the preset window opening rules are as follows: If the wind speed monitoring result is no wind and the raindrop monitoring result is no rain, then the self-locking system motor 2 drives the parallelogram mechanism 1 to operate, so that the slanted window sash 200 is fully open. Specifically, when the wind speed is determined to be 0 m / s and there is no rain, the winch motor 211 is controlled to rotate forward, and after being decelerated by the gearbox 212, it drives the rope guide 213 to rotate, releasing the steel wire rope 22. Under the gravity and mechanical transmission of the slanted window sash 200, the second member 12 of the parallelogram mechanism 1 fully opens the slanted window sash 200, as shown in the attached diagram. Figure 8 Figure a shows the window sash; where "fully open" means that the slanted window sash 200 reaches the preset maximum opening angle.

[0048] If the wind speed monitoring result indicates that the wind speed at the upper end of the fixed frame 100 is less than the preset wind speed threshold, and the raindrop monitoring result indicates no rainfall, then the self-locking system motor 2 drives the parallelogram mechanism 1 to move, so that the opening and closing state of the slanted window sash 200 is in a preset slightly open state; when it is determined that the wind speed is greater than 0 m / s and less than 3.4 m / s, and there is no rainfall, the winch motor 211 is controlled to rotate forward at a preset slightly open angle and then stop, the rope guide 213 releases part of the steel wire rope 22, and the slanted window sash 200 is slightly open, as shown in the attached figure. Figure 8 Figure b in the diagram; where the preset micro-opening angle refers to an angle smaller than the preset maximum opening angle; the preset micro-opening angle can be set by adjusting the release length of the wire rope 22 according to actual needs.

[0049] If the wind speed monitoring result indicates that the wind speed at the upper end of the fixed frame 100 is greater than or equal to the preset wind speed threshold, or if the raindrop monitoring result indicates rainfall, then the self-locking system motor 2 drives the parallelogram mechanism 1 to operate, so that the slanted window sash 200 is completely closed. Specifically, when the wind speed is determined to be greater than or equal to 3.4 m / s, or when rainfall is detected, the winch motor 211 is controlled to rotate in the reverse direction, driving the rope guide 213 to retract and tighten the steel wire rope 22. The steel wire rope 22 pulls the second rod 12 of the parallelogram mechanism 1, which, through the mechanism transmission, drives the slanted window sash 200 to move closer to the fixed frame 100 until all locking points are evenly pressed against the locking seat, thus achieving a secure closure of the slanted window sash 200. Figure 8 Figure c shows that if the external wind force continues to increase, the wind pressure acts on the slanted window sash 200. Through the self-amplifying effect of the parallelogram mechanism 1, the clamping force between the slanted window sash 200 and the fixed frame 100 is further increased, making the lock more secure.

[0050] The parallelogram mechanism self-locking device for a slanted window of the present invention comprises a parallelogram mechanism 1 installed between a fixed frame 100 and a slanted window sash 200. The parallelogram mechanism 1 limits the maximum tilt angle at which the slanted window sash 200 can be tilted open. In the parallelogram mechanism 1, a first member 11 is attached to the fixed frame 100, and a second member 12 is attached to the slanted window sash 200. The first member 11 and the second member 12 are connected by a first hinge pin 15, the second member 12 and the third member 13 are connected by a second hinge pin 16, the third member 13 and the fourth member 14 are connected by a third hinge pin 17, and the fourth member 14 and the first member 11 are connected by a fourth hinge pin 18.

[0051] In this invention, an integrated sensor 3 is installed on the upper outer side of the fixed frame 2. The integrated sensor 3 collects wind speed data and raindrop information at the upper end of the fixed frame 100, and generates a window opening control command based on the collected wind speed data and raindrop information at the upper end of the fixed frame 100. In actual operation, the wind speed sensor 31 and the raindrop sensor 32 monitor the wind speed and raindrops at the upper end of the fixed frame 100 in real time, respectively. The wind speed sensor signal processing circuit 32 compares the collected wind speed data at the upper end of the fixed frame 100 with a preset wind speed threshold to obtain the wind speed monitoring data. As a result, the raindrop information collected at the upper end of the fixed frame 100 is compared with a preset raindrop threshold by the raindrop sensing signal processing circuit 34 to obtain the raindrop monitoring result; the signal fusion module 35 is used to generate and send the window opening control command to the self-locking system motor 2 based on the wind speed monitoring result and the raindrop monitoring result; when the wind speed monitoring result is that the wind speed at the upper end of the fixed frame 100 is greater than or equal to the preset wind speed threshold, or the raindrop monitoring result is rainfall, the self-locking system motor 2 pulls back the second rod 12 through the second hinge pin 16, thereby completing the locking of the slanted window.

[0052] In this invention, the electric winch 21 is fixedly connected to the electric winch fixing hole in the winch fixing seat by fixing bolts. The winch fixing seat is fixedly connected to the motor housing 23 by winch fixing seat fixing bolts, thereby fixing the electric winch 21 in the motor housing 23. The motor housing 23 is fixed to the fixing frame 100 by bolts through the housing fixing hole. When no wind speed is detected and no rainfall is detected, the window opening control command is transmitted to the self-locking system motor 2, which controls the electric winch 21 to release the steel wire rope 22, so that the slanted window sash is fully opened. When the wind speed is detected to be less than 3.4 m / s and no rainfall is detected, the window opening control command is transmitted to the self-locking system motor 2, which controls the electric winch 21 to release the steel wire rope 22, so that the slanted window sash is slightly opened. When the wind speed is detected to be greater than 3.4 m / s or rainfall is detected, the window opening control command is transmitted to the self-locking system motor 2, which controls the electric winch 21 to pull back and tighten the steel wire rope 22, so that the slanted window sash is firmly closed. In this way, the device can open and close the slanted window to different degrees according to different weather conditions.

[0053] The parallelogram mechanism-based self-locking device for inclined windows described in this invention enables all locking points of the inclined window mechanism to press simultaneously and evenly against the lock seat on the fixed frame during the locking process. By designing the rod length ratio of the parallelogram mechanism, the user can achieve a strong and uniform sealing of the entire window with a small amount of force when operating the handle. In the normal closed state, the parallelogram mechanism is moved towards a tighter lock by the force of wind pressure, and the device can automatically monitor environmental data and close the window automatically in windy or rainy weather.

[0054] The above embodiments are merely one of the implementation methods for achieving the technical solution of the present invention. The scope of protection claimed by the present invention is not limited to this embodiment, but also includes any variations, substitutions and other implementation methods that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention.
