An electric flush window anti-pinch safety protection device

Abstract

This utility model discloses an anti-pinch safety protection device for an electric flush window, relating to the field of electric flush window technology. It includes a window frame with a window hinged to its inner side. An electronic control component is located above the front end of the window, with its upper end connected to the window frame. A protective layer is provided on the side of the front end of the window frame, and a disassembly and replacement mechanism for removing and replacing the protective layer is provided at its rear end. This anti-pinch safety protection device for an electric flush window controls the opening and closing of the window via the electronic control component. When the window is closed, due to viewing angle, most of the eye is focused on the opening and closing point of the window, neglecting the hinge. This makes it easy for fingers to be pinched at the hinge. Therefore, by placing the protective layer at the window hinge, it effectively prevents fingers from being pinched when the window is opened and closed, providing better protection for the user's fingers.

Description

Technical Field

[0001] This utility model relates to the field of electric window technology, specifically to an electric flush window anti-pinch safety protection device. Background Technology

[0002] Electric flush windows require anti-pinch safety devices, primarily based on considerations such as protecting user safety, improving user experience, complying with regulations, and reducing potential risks. Traditional safety devices are inconvenient to disassemble and replace, and prolonged exposure to sunlight can shorten their lifespan and affect their future use. Normally, when the window is closed, the side furthest from the open window is more prone to pinching hands, leading to accidents.

[0003] To overcome the aforementioned deficiencies, existing technology (Chinese Patent Publication No. CN102434056A, Publication Date 2012-05-02) provides an anti-pinch system and its implementation method for household electric windows. This anti-pinch system for household electric windows is characterized by: an electroplated conductive layer disposed on the outer edge of the window and / or the inner edge of the window frame; a touch sensing circuit, the input terminal of which is electrically connected to the electroplated conductive layer; and a control unit connected to the output terminal of the touch sensing circuit for controlling the operation of the drive motor of the electric window. Compared with existing technology, by providing an electroplated conductive layer on the outer edge of the electric window and / or the inner edge of the window frame, when a user's hand or skin touches the edge of the window or window frame, the touch sensing circuit immediately senses it through the electroplated conductive layer and then notifies the control unit. The control unit immediately outputs a control signal to stop the drive motor, preventing pinching accidents. Furthermore, dynamically updating the anti-pinch current threshold avoids the protection from failing due to changes in window resistance after prolonged use. The aforementioned mechanism works by having the user's hand contact the edge of the window, and then using a control unit to output a signal to stop the drive motor from running, preventing it from continuing to operate. However, in actual use, when the window is closed, it is more likely to cause a hand to be pinched on the side away from the open window, leading to a safety accident. Utility Model Content

[0004] The purpose of this utility model is to provide an electric flush window anti-pinch safety protection device to solve the problem mentioned in the background art that when the window is closed, it is easier for a hand to be pinched on the side away from the open window, which leads to safety accidents.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric flush window anti-pinch safety protection device, comprising a window frame, a window hinged to the inner side of the window frame, an electric control component disposed above the front end of the window, and the upper end of the electric control component connected to the window frame; a protective layer disposed on the side of the front end of the window frame, and a disassembly and assembly mechanism for disassembling, washing and replacing the protective layer disposed at the rear end of the protective layer, the disassembly and assembly mechanism comprising a second limiting strip, the second limiting strip being disposed on the side of the window and the window frame respectively, a first limiting strip being slidably connected to the outer side of the second limiting strip, and the first limiting strip being connected to the protective layer; a detection mechanism for detecting finger position is disposed at both the top and bottom ends of the protective layer.

[0006] Furthermore, both the inner side and the surface of the protective layer are provided with bending grooves, and the cross-section of the bending grooves is arc-shaped.

[0007] Furthermore, the cross-section of the first limiting strip is "C" shaped, and the protective layer is fixedly connected to the groove at the top of the first limiting strip.

[0008] Furthermore, positioning plates are installed on both the left and right sides of the first limiting strip, and limiting plates matching the positioning plates are installed on the surfaces of the window frame and the window. The positioning plates are engaged and connected to the inner side of the limiting plates.

[0009] Furthermore, a locking block is engaged at the top of the limiting plate, and a locking groove matching the locking block is provided on the surface of the limiting plate, with the bottom end of the locking block passing through and extending into the interior of the positioning plate.

[0010] Furthermore, a connecting spring is wound around the outside of the card block, and the limiting plate and the card block form an elastic structure through the connecting spring.

[0011] Furthermore, the detection mechanism includes a fixing plate, which is fixedly connected to both ends of the first limiting strip, and an infrared transmitting and receiving component is fixedly connected to the inner side of the fixing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Windows can be opened and closed by electronic control components. However, when the window is closed, due to the viewing angle, most of the eye is focused on the opening and closing point on the side of the window and the hinge is ignored. Therefore, the hinge is prone to pinching fingers. By setting a protective layer at the hinge of the window, it is possible to effectively prevent fingers from being pinched when the window is opened and closed, and to better protect the user's fingers.

[0013] Furthermore, bending grooves are provided on both the surface and the inside of the protective layer. Therefore, when the window is hinged and the protective layer deforms, the protective layer will deform in accordance with the shape of the bending groove, thereby avoiding the situation where the protective layer is forcibly bent and cracked.

[0014] Furthermore, an infrared transmitter and receiver is installed in the middle of the inner side of the fixing plate. When the protective layer is removed, a finger on the hinge of the window will block the signal reception of the infrared transmitter and receiver, thereby causing the electronic control component to stop the opening and closing of the window and emit a buzzer to remind the user to pay attention to safety and reduce the occurrence of safety accidents.

[0015] 2. The first limiting strip is slidably connected to the outside of the second limiting strip. The inner locking block of the first limiting strip and the groove on the outside of the second limiting strip are mutually adapted to each other, so that the first limiting strip and the second limiting strip can achieve stable docking. Then, the positions of the first limiting strip and the second limiting strip are locked and fixed a second time by the disassembly and assembly mechanism, thereby effectively preventing the separation of the first limiting strip and the second limiting strip during the use of the protective layer. The locking block is engaged with the inside of the locking groove. The length of the locking block passes through the positioning plate, thereby restricting the position of the first limiting strip. The positioning plates at both ends of the first limiting strip are respectively engaged on one side between the limiting plates. Then, the locking block passes through the positioning plate and the limiting plate to achieve limiting and locking.

[0016] Furthermore, the elastic force of the connecting spring can assist the locking block in resetting its position, increasing the flexibility of the locking block during repeated pulling and pulling. Attached Figure Description

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

[0025] Example 1: As Figures 1-5 The technical solution shown addresses the problem that, when the window is closed, the side furthest from the open window is more prone to pinching fingers, leading to safety accidents. This electric flush window anti-pinch safety protection device discloses a protection mechanism including a window frame 1, a window 2 hinged to the inner side of the window frame 1, an electrical control component 3 located above the front end of the window 2, and the upper end of the electrical control component 3 connected to the window frame 1. A protective layer 6 is provided on the side of the front end of the window frame 1, and bending grooves 7 are formed on both the inner side and the surface of the protective layer 6, with the cross-section of the bending grooves 7 being arc-shaped.

[0026] In this example, such as Figure 1 As shown, the opening and closing of window 2 can be controlled by the electronic control component 3. However, when window 2 is closed, due to the viewing angle, most of the eye is focused on the opening and closing point of window 2, neglecting the hinge. This makes it easy for fingers to be pinched at the hinge. Therefore, by placing the protective layer 6 at the hinge of window 2, it is possible to effectively prevent fingers from being pinched when window 2 is opened and closed, thus providing better protection for the user's fingers. Figure 1 and Figure 4 As shown, bending grooves 7 are provided on both the surface and the inner side of the protective layer 6. Therefore, when the window 2 is hinged and the protective layer 6 deforms, the protective layer 6 will deform with the shape of the bending groove 7, thereby avoiding the situation where the protective layer 6 is forcibly bent and breaks.

[0027] Example 2: Figure 2 , Figure 3 and Figure 6The technical solution shown addresses the problem that the protective layer 6, being located near the window 2, is easily exposed to direct sunlight, leading to a shortened lifespan and inconvenient replacement of the first and second limiting strips 4 and 5 due to prolonged sunlight exposure. This electric flush window anti-pinch safety protection device discloses a disassembly and assembly mechanism. The rear end of the protective layer 6 is equipped with this mechanism for disassembling, cleaning, and replacing the protective layer 6. The disassembly and assembly mechanism includes the second limiting strip 5, which is respectively located on the sides of the window 2 and the window frame 1. The outer side of the second limiting strip 5 is slidably connected to the first limiting strip 4, and the first limiting strip 4 is connected to the protective layer 6. The cross-section is C-shaped, and the protective layer 6 is fixedly connected to the groove at the top of the first limiting strip 4; positioning plates 10 are installed on both the left and right sides of the first limiting strip 4, and limiting plates 11 matching the positioning plates 10 are installed on the surfaces of the window frame 1 and the window 2, with the positioning plates 10 snapped into the inner side of the limiting plates 11; a locking block 12 is snapped into the top of the limiting plate 11, and a locking groove 14 matching the locking block 12 is opened on the surface of the limiting plate 11, with the bottom end of the locking block 12 passing through and extending into the interior of the positioning plate 10; a connecting spring 13 is wound around the outside of the locking block 12, and the limiting plate 11 and the locking block 12 form an elastic structure through the connecting spring 13.

[0028] In this example, such as Figure 4 As shown, the first limiting strip 4 is slidably connected to the outside of the second limiting strip 5. The inner locking block of the first limiting strip 4 and the groove on the outside of the second limiting strip 5 are mutually adapted to each other, thereby enabling a stable connection between the first limiting strip 4 and the second limiting strip 5. Then, the positions of the first limiting strip 4 and the second limiting strip 5 are locked and fixed a second time by the disassembly and assembly mechanism, thereby effectively preventing the separation of the first limiting strip 4 and the second limiting strip 5 during the use of the protective layer 6; as shown. Figure 6 As shown, the locking block 12 is engaged inside the slot 14. The length of the locking block 12 passes through the positioning plate 10, thereby limiting the position of the first limiting strip 4. The positioning plates 10 at both ends of the first limiting strip 4 are respectively engaged on one side between the limiting plates 11. Then, the locking block 12 passes through the positioning plate 10 and the limiting plate 11 to achieve limiting and locking. The elastic force of the connecting spring 13 can assist the locking block 12 in resetting its position, increasing the flexibility of the locking block 12 when repeatedly pulled out.

[0029] Example 3: Figure 1 , Figure 2 and Figure 5The technical solution shown addresses the problem of difficulty in timely detection of finger position during anti-pinch protection: the electric flush window anti-pinch safety protection device discloses a detection mechanism. The top and bottom of the protective layer 6 are equipped with detection mechanisms for detecting finger position. The detection mechanism includes a fixing plate 9, which is fixedly connected to both ends of the first limiting strip 4. An infrared transmitting and receiving component 8 is fixedly connected to the inner side of the fixing plate 9.

[0030] In this example, such as Figure 5 As shown, an infrared transmitting and receiving component 8 is located at the middle position of the inner side of the fixing plate 9. When the protective layer 6 is removed, a finger at the hinge of the window 2 will block the signal reception of the infrared transmitting and receiving component 8, thereby causing the electronic control component 3 to stop the opening and closing of the window 2 and issue a buzzer reminder, promptly alerting the user to safety and reducing the occurrence of safety accidents. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
