Description

Technical Field

[0001] This invention relates to the technical field of hydraulic window opening devices, specifically to a hydraulic window opening device. Background Technology

[0002] Attic homes, compared to other standard housing types, tend to be more expensive due to poorer lighting and ventilation. The windows in these attic homes are primarily skylights. Skylights are a common architectural feature; they are windows created by openings in the roof and are often used for ventilation or lighting. They can also decorate the house, adding to the aesthetics of the overall structure. Therefore, some homes with atriums also use skylights to increase natural light and further enhance comfort.

[0003] Existing skylight opening mechanisms typically involve using hydraulic rods or other electric actuators to drive and support the other side of the window frame around one side of the window frame, allowing the window to open outwards. This limits the size of the opening. Furthermore, this method presents several technical problems: Firstly, the exterior of the window is frequently exposed to rain and dust, resulting in dirt buildup on the outer panel. Regular cleaning is necessary to maintain the cleanliness of the window glass. Current technology makes cleaning the exterior of the window very cumbersome, requiring specialized magnetic cleaning devices or specialized cleaning workers. This increases cleaning costs and introduces inherent risks, reducing the practicality of the opening mechanism. Summary of the Invention

[0004] This invention proposes a hydraulic window opening device that allows the window frame to open along with the entire window, enabling the window opening to be fully opened, increasing the ventilation effect inside the house, while also facilitating the cleaning of the outer panel of the skylight and reducing the danger during cleaning, thereby increasing the practicality of the window opening device.

[0005] The technical solution of the present invention is as follows:

[0006] A hydraulic window opening device includes an outer window frame and a window frame mounting base. The outer window frame slides against the outside of the window frame mounting base. The device is characterized by an electric cylinder fixedly connected to the outside of the window frame mounting base for adjusting the window opening size. Window opening components are connected to both sides of the electric cylinder, which, driven by the electric cylinder, move and rotate the outer window frame. A counterweight abuts against the telescopic shaft of the electric cylinder, providing stable cooperation for the window opening components on both sides. Limiting plates abut against both sides of the outer window frame, limiting the movement and rotation of the outer window frame. Each limiting plate is fixedly connected to the window frame mounting base.

[0007] Furthermore, each of the window opening components includes a first protective shell and two linkage plates. Both linkage plates are fixed to the outer window frame on the side facing the electric cylinder. The first protective shell is fixedly connected to the window frame mounting base. A transmission column is rotatably connected to the first protective shell. A sprocket is fixedly connected to the end of the transmission column facing the electric cylinder. A chain is fitted on the sprocket. One end of the chain is detachably hinged to the counterweight, and the other end of the chain is detachably hinged to the linkage plate.

[0008] Furthermore, a first gear is rotatably connected inside the first protective shell, and a hydraulic rod is detachably fixedly connected to the first gear. The telescopic shaft of the hydraulic rod is hinged to the side of the outer window frame. A fixing collar is fitted on the hydraulic rod, and the fixing collar is detachably fixedly connected to the first gear. A second gear is fixedly connected to the transmission column, and the second gear meshes with the first gear.

[0009] Furthermore, the rotation angle of the first gear must be maintained between 0° and 80°.

[0010] Furthermore, each of the limiting plates is provided with a first limiting groove, which is an inclined groove. A second limiting groove communicating with the first limiting groove is provided on the side of the first limiting groove facing the electric cylinder. Positioning posts are fixedly connected to both sides of the outer window frame, and each positioning post abuts against the inner wall of each first limiting groove.

[0011] Furthermore, a first handle is fixedly connected to the side of the outer window frame away from the linkage plate, and the weight of the outer window frame is less than the weight of the counterweight.

[0012] Furthermore, two limiting nuts are fixedly connected to the telescopic shaft of the electric cylinder. The distance between the two limiting nuts is equal to the thickness of the counterweight. A first slot matching the diameter of the telescopic shaft of the electric cylinder is opened on the counterweight. A second slot communicating with the first slot is opened on one side of the first slot. The opening of the second slot is larger than the diameter of the limiting nut. Two second handles are fixedly connected to the counterweight.

[0013] Furthermore, two distance sensors for identifying the distance between the counterweight and the window frame mounting base are fixedly connected to the window frame mounting base. A second protective shell for protecting components such as the electric cylinder is fixedly connected between the two first protective shells. A lighting lamp is fixedly connected inside the second protective shell.

[0014] The beneficial effects of this invention are as follows:

[0015] In this invention, the movement of the electric cylinder's telescopic shaft allows the window to be in three states: closed, fully open, and with the outer window frame flipped. In the fully open state, the electric cylinder can directly control and adjust the window opening components on both sides via the counterweight, thereby adjusting the distance the outer window frame moves on the limiting plate to ensure the user's needs are met and to increase the ventilation effect of the building. In the flipped state, the limiting plate moves the outer window frame a certain distance and then limits it, allowing the outer window frame to flip around one side of the outer window frame. This makes it easier for the user to clean the outer glass surface of the outer window frame, reducing the danger during operation and thus increasing the practicality of the device.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1-6 As shown, this embodiment proposes a hydraulic window opening device, including an outer window frame 12 and a window frame mounting base 4. The outer window frame 12 slides against the outside of the window frame mounting base 4. An electric cylinder 32, which precisely adjusts the window opening size, is fixedly connected to the outside of the window frame mounting base 4. A window opening assembly 2, which moves and flips the outer window frame 12 through the electric cylinder 32, is connected to one side of the electric cylinder 32. The telescopic shaft of the electric cylinder 32 abuts against a counterweight 31 that provides stable cooperation with the window opening assembly 2. The movement of the telescopic shaft of the electric cylinder 32 allows the window to be in three states: closed, fully open, and flipped. In the fully open state, the electric cylinder 32 can directly control and adjust the window opening assemblies 2 on both sides through the counterweight 31 to adjust the movement distance of the outer window frame 12 on the limiting plate 27, ensuring the user's needs. The limiting plates 27 on both sides can also be connected by two horizontal plates. Both ends are hinged to the window frame mounting base 4 near the connection position of the hydraulic rod 25 and the outer window frame 12, and to the lower side of the outer window frame 12, respectively. When the outer window frame 12 is upward, the hydraulic rod 25 will pop out to allow the outer window frame 12 to flip around the horizontal plates on both sides. The linkage plate 26 connected to the window opening assembly 2 is fixedly connected to the side of the outer window frame 12 facing the electric cylinder 32. Two limiting plates 27 that limit the movement and flipping of the outer window frame 12 are abutted against both sides of the outer window frame 12. Each limiting plate 27 is fixedly connected to the window frame mounting base 4. When the outer window frame 12 is flipped, the limiting plate 27 limits the movement of the outer window frame 12 after it has moved a certain distance, allowing the outer window frame 12 to flip around one side of the outer window frame 12. This makes it easier for users to clean the outer glass surface of the outer window frame 12, reduces the danger during operation, and increases the practicality of the device.

[0027] like Figures 1-5As shown, each window opening assembly 2 includes a first protective shell 210, which is fixedly connected to the window frame mounting base 4. The first protective shell 210 is used to protect the internal components and increase their service life. A transmission column 24 is rotatably connected to the first protective shell 210. A sprocket 29 is fixedly connected to the end of the transmission column 24 facing the electric cylinder 32. A chain 28 is sleeved on the sprocket 29. One end of the chain 28 is detachably hinged to the counterweight 31, and the other end is detachably hinged to the linkage plate 26. A first gear 21 is rotatably connected to... Inside the first protective shell 210, a hydraulic rod 25 is detachably fixed to the first gear 21. The chain 28 drives the sprocket 29 to rotate, thereby causing the angle of the hydraulic rod 25 to change. The telescopic shaft of the hydraulic rod 25 is hinged to the side of the outer window frame 12. The hydraulic rod 25 serves as a buffer when the outer window frame 12 moves. After the hydraulic rod 25 is flipped to a certain angle, the return of the telescopic shaft of the hydraulic rod 25 can cause the outer window frame 12 to flip around a point. After the outer window frame 12 is flipped, it is convenient for the user to clean the outer glass panel of the outer window frame 12, thereby reducing the danger during cleaning.

[0028] like Figure 2 As shown, the fixing collar 22 is fitted onto the hydraulic rod 25. The fixing collar 22 is detachably fixedly connected to the first gear 21. The second gear 23 is fixedly connected to the transmission column 24. The second gear 23 meshes with the first gear 21.

[0029] like Figure 2 As shown, the rotation angle of the first gear 21 should be kept between 0° and 80° so that the number of teeth of the first gear 21 and the second gear 23 is relatively large. Even if the first gear 21 rotates multiple times, it will only rotate a certain angle. This allows the continuous upward movement of the outer window frame 12 to drive the hydraulic rod 25 to gradually rotate with the first gear 21. As a result, the outer window frame 12 can rotate outward around one side of the outer window frame 12 under the action of the hydraulic rod 25.

[0030] like Figure 2 and Figure 3As shown, each first limiting groove 271 is formed on each limiting plate 27. The first limiting groove 271 is an inclined groove. The second limiting groove 272, which communicates with the first limiting groove 271, is formed on the side of the first limiting groove 271 facing the electric cylinder 32. Two positioning posts 273 are fixedly connected to both sides of the outer window frame 12. Each positioning post 273 abuts against the inner wall of each first limiting groove 271. When the chain 28 moves the outer window frame 12, the sliding of the positioning posts 273 on the inner wall of the first limiting groove 271 allows the outer window frame 12 to move stably. At the same time, the first limiting groove 271 causes the outer window frame 12 to gradually increase the distance between itself and the window frame mounting base 4 during movement, reducing the distance between itself and the window frame. While the window frame 12 and the window frame mounting base 4 are worn, space is left for the outer window frame 12 to flip. When the positioning post 273 slides to the position of the second limiting groove 272, under the action of gravity, the positioning post 273 will bring the outer window frame 12 into the second limiting groove 272. When the 273 is subject to other limiting actions during the sliding, and it is not enough for the positioning post 273 to slide into the second limiting groove 272, after the chain 28 is reset, after the chain 28 has a certain amount of slack, the positioning post 273 can still be engaged into the second limiting groove 272 under the action of the gravity of the outer window frame 12, limiting the outer window frame 12 and laying the foundation for the flipping of the outer window frame 12.

[0031] like Figure 2 and Figure 3 As shown, the first handle 11 is fixedly connected to the outer window frame 12 on the side away from the linkage plate 26. When the outer window frame 12 is flipped in the opposite direction, it needs to be reset. A person can hold the first handle 11 and apply an outward force to the outer window frame 12 to push the positioning post 273 away from the second limiting groove 272, so that the outer window frame 12 can have the ability to reset. At the same time, the first handle 11 also makes it convenient for people on the outside to exert more force on the outer window frame 12 in the event of a fire or power outage, so that the outer window frame 12 can be opened more easily. The weight of the outer window frame 12 is less than the weight of the counterweight 31. After the counterweight 31 is no longer limited by the electric cylinder 32, the counterweight 31 can also move the outer window frame 12 according to its own weight, which further facilitates the rescue by firefighters.

[0032] like Figure 2 and Figure 4As shown, two limiting nuts 321 are fixedly connected to the telescopic shaft of the electric cylinder 32. The distance between the two limiting nuts 321 is equal to the thickness of the counterweight 31. The two limiting nuts 321 abut against the counterweight 31, thereby limiting the counterweight 31. A first slot 311, matching the diameter of the telescopic shaft of the electric cylinder 32, is formed on the counterweight 31. A second slot 312, communicating with the first slot 311, is formed on one side of the first slot 311. The opening of the second slot 312 is larger than the diameter of the limiting nuts 321. Two second handles 35 are fixedly connected to the counterweight 31. The electric cylinder 32 can be controlled by a separate backup power supply to prevent the equipment from being interrupted during power outages. While unusable in daily life, the electric cylinder 32 will automatically shut off due to fire or other reasons, indicating that it is not functioning properly. In cases where rescue is needed by opening the window from the outside, the two second handles 35 can be pushed horizontally towards the window frame mounting base 4, causing the telescopic shaft of the electric cylinder 32 to slide from the first slot 311 to the second slot 312. This allows the counterweight 31 to fall freely, thereby moving the outer window frame 12 and opening the window. After the power is restored, it can be used again. The device has multiple functions and can be reused, increasing its practicality and facilitating operation by firefighters, thus protecting the property safety of the user.

[0033] like Figure 4 and Figure 5 As shown, two distance sensors 36, used to identify the distance between the counterweight 31 and the window frame mounting base 4, are fixedly connected to the window frame mounting base 4. When the counterweight 31 is too close to the window frame mounting base 4, it indicates that someone outside is trying to illegally enter the house. The distance sensor 36 transmits an electrical signal to the buzzer or other alarm device to warn the people inside the house. The lighting lamp 34 is fixedly connected inside the second protective shell 33 and is used to provide illumination when the window is opened in the dark.

[0034] The working principle of this embodiment is as follows:

[0035] Closed state: This refers to the window being closed, such as... Figure 1 As shown, the counterweight 31 is controlled by the electric cylinder 32. Through the weight of the outer window frame 12 and the limiting plate 27, the outer window frame 12 completely blocks the window on the window frame mounting base 4.

[0036] Fully open: The electric cylinder 32 directly controls the distance the counterweight 31 moves down, so that the chain 28 drives the outer window frame 12 to move to the window size required by the user. When the user needs to fully open the window, the outer window frame 12 moves to the positioning post 273 and moves into the second limit groove 272 to stop. At this time, under the movement of the outer window frame 12 of the hydraulic rod 25, most of the telescopic shaft is pushed into the main body of the hydraulic rod 25, which plays a stabilizing and buffering role in the movement of the outer window frame 12. At this time, the positioning post 273 will move to the second limit groove 272 or will not move completely into the second limit groove 272 due to other limitations.

[0037] The outer window frame 12 flips: When the outer window frame 12 is not subject to other limiting forces, the positioning pin 273 moves into the second limiting groove 272, the electric cylinder 32 moves the counterweight 31 upward, causing the sprocket 29 to rotate continuously in the opposite direction as the chain 28 moves, thereby causing the second gear 23, which is coaxial with the sprocket 29, to rotate. This causes the first gear 21, which meshes with the second gear 23, to flip at a certain angle and then reverse. When the hydraulic rod 25 flips to a certain distance, because the positioning pin 273 is engaged in the second limiting groove 272, the outer window frame 12 flips. When one side of the outer window frame 12 is restricted, the chain 28, driven by the reset action of the electric cylinder 32, causes the other side of the outer window frame 12 to flip downwards, thereby enabling the outer window frame 12 to flip and allowing the user to safely contact and clean the outer glass panel of the outer window frame 12. Similarly, even when the outer window frame 12 is restricted, the positioning post 273, under the action of gravity, will still engage the outer window frame 12 into the second limiting groove 272 when the chain 28 is reset, laying the foundation for the flipping of the outer window frame 12.

[0038] Reset: After the telescopic shaft of the electric cylinder 32 moves downward to its maximum distance, the outer window frame 12 returns to the fully open state. Then, the user grasps the first handle 11 and pushes the outer window frame 12 outward to push the positioning pin 273 out of the second limiting groove 272. Then, the telescopic shaft of the electric cylinder 32 is reset, so that the outer window frame 12 moves along the inner wall of the first limiting groove 271 through the positioning pin 273. Finally, the outer window frame 12 is fully reset.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
