DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Please refer to Figures 1 to 6 The utility model provides a kind of child anti-falling mechanism, including window frame 1, window leaf 2, driving member 3, measurement and control module 4 and hinge rod 5, the sliding groove 11 is set in the window frame 1, the first hinge block 12 and the second hinge block 13 are equipped in the sliding groove 11, the first hinge block 12 is fixedly connected in the sliding groove 11, the second hinge block 13 is slidably connected in the sliding groove 11, the window leaf 2 includes two horizontal rods 21 and two vertical rods 22, the two horizontal rods 21 and two the vertical rod 22 is connected to form frame structure head to tail, one end of the hinge rod 5 is hinged with the middle part of the horizontal rod 21, the other end is hinged with first hinge block 12, the driving member 3 and the measurement and control module 4 are all located on the window frame 1, the driving member 3 is electrically connected with the measurement and control module 4, the power output end of the driving member 3 is hinged with the vertical rod 22 away from the second hinge block 13, the measurement and control module 4 is used to detect object close to the window frame 1, to control the opening and closing of the window leaf 2 by the driving member 3.

[0022] In the application, the cross section of sliding groove 11 is inverted T structure, correspondingly, the cross section of second hinge block 13 is also inverted T structure.

[0023] The specific process of closing the window leaf 2 on the window frame 1 in the application is as follows: under the driving of the driving member 3, the vertical rod 22 approaches the window frame 1, and at the same time, the horizontal rod 21 drives the hinged rod 5 to rotate towards the direction of the window frame 1, and the included angle between the horizontal rod 21 and the window frame 1 gradually decreases. At the same time, the second hinged block 13 slides in the sliding groove 11 away from the first hinged block 12, so that the window is gradually fully closed on the window frame 1. Compared with the side of the window leaf 2 directly hinged on the window frame 1, the both sides of the window leaf 2 can be cleaned when needed in the embodiment; or compared with the opening window mode of directly translating the window leaf 2, the opening window area of the application is larger, and the ventilation effect is better.

[0024] The driving member 3 in the application can adopt a gas cylinder, an electric cylinder or a chain type window opener. If a gas cylinder or an electric cylinder is adopted for driving, the other end of the gas cylinder or the electric cylinder needs to be hinged on the window frame 1. If a chain type window opener is adopted, the chain type window opener is fixed on the window frame 1, and the other end of the chain is hinged with the vertical rod 22. The above-mentioned driving member 3 is a commonly used driving device for those skilled in the art, which can be applied according to the actual situation.

[0025] In addition, parents can connect the measurement and control module 4 through a mobile phone APP and other smart devices to remotely monitor and control the state of the window leaf 2, and can know the safety situation at home at any time no matter where they are. At the same time, the measurement and control module 4 also supports voice control, timing switch and other convenient functions, which improves the use experience of users.

[0026] In one feasible implementation, the measurement and control module 4 is equipped with a camera 41 and an infrared sensor 42. The camera 41 is used to capture images of objects near the window frame 1, and the infrared sensor 42 is used to detect the distance between the object and the object near the window frame 1. In this application, the camera 41 acquires an image of a person near the window, and then, relying on computer vision and deep learning technologies, uses a trained model to classify and analyze the person in the image. For example, it can determine whether the person is a child through face detection. The camera 41 recognizes faces using computer vision technology. Once a face is detected, the camera 41 can infer the age range of the person in the image using a trained age estimation model. These models are typically trained based on deep neural networks (DNNs) and can predict a person's age range based on facial features. Through these features, the system can determine whether the person is an adult or a child. Age can also be identified through body proportions. Children and adults differ significantly in height and body proportions (such as the head-to-body ratio), and computer vision technology can use these features to help distinguish between adults and children. The infrared sensor 42 determines the distance between the person and the window by utilizing the principle of infrared light emission and reflection. The cooperation between camera 41 and infrared sensor 42 greatly improves the accuracy of detection. The aforementioned technology for detecting whether someone is a child using camera 41 and infrared sensor 42 is a relatively mature technique widely used in the field of smart technology. Those skilled in the art can adopt appropriate detection techniques according to the actual situation, which will not be elaborated further here.

[0027] In one feasible embodiment, the control module 4 is recessed on one side facing the window frame 1 to form a recess 43. The recess 43 is equipped with an emergency button 44, which is electrically connected to the drive unit 3. The emergency button 44 is used to control the opening of the window leaf 2 via the drive unit 3. In this embodiment, the recess 43 can successfully avoid attracting children's attention and simultaneously conceal the emergency button 44, effectively preventing accidental activation by children. Exemplarily, the emergency button 44 of this application consists of a pressable button, a mechanical switch built into the control module 4, and an elastic element. When the button is pressed, the mechanical switch within the control module 4 is triggered, thereby controlling the drive unit 3 to quickly open the window leaf 2. Emergency situations include, but are not limited to, situations such as a fire, where opening the window leaf 2 can help with ventilation, reduce smoke accumulation, and provide fresh air; or chemical or toxic gas leaks (such as natural gas leaks), where opening the window leaf 2 helps reduce the concentration of harmful gases indoors, thereby reducing the risk of poisoning.

[0028] In an available embodiment, the edge of the measurement and control module 4 is formed with a rounded corner. In this embodiment, if the edge of the measurement and control module 4 is sharp, it is easy to cause scratches or collision injuries to children. By setting the rounded corner, the edge becomes smooth, which can effectively reduce the injuries caused by accidental collisions of children.

[0029] In an available embodiment, the articulated rod 5 is articulated with the first articulated block 12 through an articulated assembly 6, the articulated assembly 6 comprising an articulated cylinder 61, an articulated shaft 62 and a spring 63, the articulated cylinder 61 being provided with an upper stop plate 611 for abutting against the articulated rod 5, the articulated shaft 62 being provided with a lower stop plate 621 for abutting against the first articulated block 12, the articulated cylinder 61 being a hollow structure for inserting the articulated shaft 62, the spring 63 being arranged in the articulated cylinder 61, two ends of the spring 63 being connected with the articulated cylinder 61 and the articulated shaft 62 respectively, a plurality of clamping grooves 612 being formed on the peripheral wall surface of the articulated cylinder 61, the clamping grooves 612 comprising a straight section 613 and a clamping section 614 which are in communication with each other, a clamping block 622 being protruded on the peripheral wall surface of the articulated shaft 62, the spring 63 being used to press the clamping block 622 which is slid from the straight section 613 into the clamping section 614 in the clamping section 614. Specifically, when connecting the articulated rod 5 and the first articulated block 12, the articulated shaft 62 is inserted from below the first articulated block 12, so that the lower stop plate 621 abuts against the first articulated block 12, the spring 63 is placed in the articulated cylinder 61, and the articulated cylinder 61 is inserted from above the articulated rod 5. It is worth noting that, in this process, the straight section 613 needs to be aligned with the clamping block 622 so that the upper stop plate 611 abuts against the articulated rod 5, and at this time the spring 63 is compressed. The articulated cylinder 61 is screwed, so that the clamping block 622 is slid from the straight section 613 into the clamping section 614. Under the elastic force of the spring 63, the clamping block 622 is tightly abutted in the clamping section 614, thereby completing the connection of the articulated rod 5 and the first articulated block 12. This embodiment has a simple structure and is convenient to install.

[0030] In one possible implementation, the upper stop plate 611 is hinged with a screw handle 615, and the upper stop plate 611 and the hinge rod 5 are both provided with a limiting groove 64 which is adapted to the screw handle 615 and used to accommodate the screw handle 615 to limit the rotation of the upper stop plate 611. In order to avoid the rotation of the hinge cylinder 61 caused by the rotation of the hinge rod 5 and the first hinge block 12, the screw handle 615 is accommodated in the limiting groove 64 to limit the rotation of the upper stop plate 611 and the hinge cylinder 61, thereby greatly improving the safety of the window leaf 2. In addition, in this embodiment, the screw handle 615 can be used to disassemble the hinge rod 5 and the first hinge block 12 in an emergency. Specifically, the screw handle 615 is flipped upward to make the screw handle 615 disengage from the limiting groove 64 and rotate the screw handle 615 to make the clamping block 622 slide from the clamping segment 614 to the straight segment 613. Under the elastic force of the spring 63, the hinge cylinder 61 is ejected to complete the disassembly. This embodiment can be applied in the case where the emergency button 44 fails. Since the hinge rod 5 and the first hinge block 12 are disassembled, there is one less force support point, which greatly reduces the difficulty of opening the window leaf 2 in an emergency.

[0031] In one possible implementation, the upper surface of the upper stop plate 611 is rotationally connected with a limiting plate 65 which is formed with a notch used to align with the limiting plate 65 for flipping the screw handle 615. Specifically, the limiting plate 65 is a circular piece with one side cut by a part, and the cut part forms the notch. After the connection of the hinge rod 5 and the first hinge block 12 is completed, the limiting plate 65 is rotated to make the notch disengage from the screw handle 615, thereby limiting the upward flipping of the screw handle. When disassembly is needed, the notch is aligned with the limiting plate 65 for the upward flipping of the screw handle 615. This embodiment can avoid the unintentional flipping of the screw handle by children to take down the hinge cylinder 61, thereby forming multiple protections for the hinge.

Therefore, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalency of the claims are intended to be embraced therein.
