Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hidden doors, in particular to an inward-pushing type hidden door. BACKGROUND

[0002] As a common facility in modern commercial places, the inward-pushing type hidden door is widely used due to its space saving and elegant appearance. With the progress of architectural aesthetics and technology, the design of the hidden door not only needs to meet the basic safety and practicality requirements, but also should have high concealment and convenient operation. In recent years, various forms of electric hidden doors have gradually become the mainstream products in the market, which can realize automatic opening and closing, greatly improving the user experience and living comfort.

[0003] In the existing design of the inward-pushing type hidden door, the commonly used way is to use a motor to drive the door leaf to move linearly along the guide rail to complete the opening and closing action of the door. That is, a guide rail is preset inside the door frame, and the motor is installed on the side of the door frame. The motor drives the transmission belt to move the door leaf.

[0004] However, most of the electric inward-pushing type hidden doors on the market cannot work normally in the case of sudden power failure, which leads to the safety hazard of users being trapped or facing emergency situations. This problem is particularly prominent because modern buildings often rely on electricity to operate many devices. Once a power failure occurs, it is crucial to ensure the key access. SUMMARY

DETAILED DESCRIPTION

[0059] The following will be combined with the drawings Figures 1-6Further details of the application are described below.

[0060] In combination Figure 1 And Figure 2 The embodiments of the present application disclose an inner pushing type hidden door, comprising a door frame 1 and a door leaf 11, the door frame 1 is horizontally provided with a moving groove 12 at the top, and further comprising a sliding rail 13, a sliding assembly, a motor 14, a matching piece 3, a driving piece 4, a driving rack 15, a first gear 16, the sliding rail 13 is fixedly arranged in the moving groove 12, the sliding direction of the sliding rail 13 is parallel to the opening and closing direction of the door leaf 11, a matching groove 17 is horizontally arranged on the side wall of the sliding rail 13, and the matching groove 17 is communicated with the moving groove 12; the sliding assembly is slidably arranged on the sliding rail 13; the motor 14 is fixedly arranged on the top of the door frame 1, and the motor 14 drives the sliding assembly to slide on the sliding rail 13; the matching piece 3 is slidably arranged in the matching groove 17; the driving piece 4 is fixedly arranged on the upper end of the door frame 1; the driving rack 15 is slidably arranged on the driving piece 4, and the driving rack 15 is connected with the driving piece 4 through a mounting piece 5; the first gear 16 is fixedly arranged on one side of the sliding assembly, and the first gear 16 is engaged with the driving rack 15, so as to drive the sliding assembly to move after power-off and control the opening and closing of the door leaf 11.

[0061] In the embodiments of the present application, the door frame 1 is square-shaped, and the specification and strength of the door frame 1 can meet the movement of the door leaf 11. The material of the door leaf 11 is arranged according to specific use conditions, and the embodiments of the present application are not limited in particular. The moving groove 12 is a through groove, that is, it penetrates through the door frame 1. It should be noted that one end of the moving groove 12 has an inclination angle, and the angle can meet the movement of the door leaf 11 and can be flush with the wall surface when closed. Two moving grooves 12 are arranged in parallel, and the two moving grooves 12 are arranged in parallel. The moving groove 12 is provided with two moving grooves 12, which can meet the stability of the door leaf 11 during movement. The sliding rail 13 can be integrally formed in the moving groove 12, or can be fixed in the moving groove 12 by welding or bolting, and the shape of the sliding rail 13 is consistent with the shape of the moving groove 12. The driving rack 15 is rectangular-shaped, the driving rack 15 is engaged with the first gear 16, and it should be noted that the driving rack 15 can slide by being embedded in the top of the door frame 1, or can slide by being provided with a groove for the sliding of a fixing block on the side wall of the driving rack 15. As long as the driving rack 15 can slide, the sliding mode of the driving rack 15 is well known to those skilled in the art, and therefore, the embodiments of the present application will not be described in detail.

[0062] It should be noted that the bottom of the door frame 1 is provided with an infrared sensor, and the infrared sensor is electrically connected with the motor 14. It is used to sense whether the person is close to the door leaf 11. If it is detected that the person is close to the door leaf 11, the motor 14 is controlled to start, so as to open the door leaf 11. If it is detected that the door leaf 11 is not close to the person, the motor 14 is controlled to close the door leaf 11.

[0063] In specific use, the motor 14 is started, so that the output shaft of the motor 14 drives the sliding assembly to open and close the door leaf 11. When the power is off, the door leaf 11 is pressed in the opening direction, so that the door leaf 11 slides on the sliding rail 13. In the process of sliding, the cooperating part 3 pushes the driving part 4 to move, and at the same time the driving part 4 drives the driving rack 15 to slide in the process of moving. Since the driving rack 15 is engaged with the first gear 16, the driving rack 15 drives the first gear 16 to rotate in the process of sliding. The first gear 16 drives the sliding assembly to slide on the sliding rail 13, and further drives the door leaf 11 to open, thereby reducing the problem that the motor 14 cannot drive the door leaf 11 to open due to sudden power failure.

[0064] In combination with Figure 1 and Figure 2 , specifically, the sliding assembly includes a second gear 21, a pulley block 22 and a sliding rack 23. The second gear 21 is rotatably arranged at the upper end of the door frame 1. One end of the second gear 21 is fixedly connected with the output shaft of the motor 14, and the other end of the second gear 21 is fixedly connected with the first gear 16. The pulley block 22 is slidably arranged on the sliding rail 13. The pulley block 22 includes a first pulley 221 rotatably arranged on one side of the sliding rail 13, a second pulley 222 rotatably arranged on the side of the sliding rail 13 away from the first pulley 221, a connecting plate 223, one end of the connecting plate 223 being rotatably connected with the first pulley 221, the other end of the connecting plate 223 being rotatably connected with the second pulley 222, and the bottom of the connecting plate 223 being fixedly connected with the door leaf 11. The lower end of the sliding rack 23 is fixedly connected with the top of the connecting plate 223, and the upper end of the sliding rack 23 is engaged with the second gear 21.

[0065] In the embodiment of the present application, the second gear 21 is disc-shaped. Since the moving groove 12 has an inclination angle, the sliding rack 23 will displace when sliding at the inclination angle. Therefore, the thickness of the second gear 21 can satisfy that the sliding rack 23 can still engage with the second gear 21 in the process of displacement. The first pulley 221 and the second pulley 222 are disc-shaped, and the rotation axes of the first pulley 221 and the second pulley 222 are perpendicular to the sliding direction of the sliding rail 13. The connecting plate 223 is square-shaped. The connection between the connecting plate 223 and the door leaf 11 and the connection between the connecting plate 223 and the sliding rack 23 can be integrally formed. It should be noted that the door leaf 11 and the connecting plate 223 are fixedly connected through a support plate to ensure the stability of the connection between the door leaf 11 and the connecting plate 223.

[0066] In specific use, the motor 14 drives the second gear 21 to rotate. Since the second gear 21 is engaged with the sliding rack 23, the second gear 21 drives the sliding rack 23 to slide when rotating, i.e. the sliding rack 23 drives the first pulley 221 and the second pulley 222 to rotate in the process of sliding, and the first pulley 221 and the second pulley 222 drive the connecting plate 223 to move when rotating, and the connecting plate 223 drives the door leaf 11 to move until the door leaf 11 is completely opened. When it is needed to close the door leaf 11, the motor 14 works reversely, and the output shaft reversely rotates to drive the second gear 21 to reversely rotate. Similarly, the rotation of the second gear 21 is transmitted to the pulley block 22 through the sliding rack 23, so that the pulley block 22 reversely slides along the sliding rail 13. With the reverse sliding of the pulley block 22, the connecting plate 223 drives the door leaf 11 to move until the door leaf 11 is completely closed.

[0067] In combination Figure 2 and Figure 3 In a specific embodiment, the door frame 1 is vertically provided with a mounting groove 35 at the top, the matching groove 17 is communicated with the mounting groove 35, the matching piece 3 comprises a first spring 31, a closing plate 32, a matching pipe 33 and a matching block 34, the first spring 31 is provided with two, and the two first springs 31 are fixedly arranged on the two sides of the matching groove 17; the closing plate 32 is provided with two, each closing plate 32 is slidingly arranged in the matching groove 17, and the ends of the two closing plates 32 away from each other are fixedly connected with the ends of the first springs 31 away from the side wall of the matching groove 17, and the ends of the closing plates 32 close to each other are fixedly provided with electromagnets, and the electromagnets are electrically connected with a power supply; the matching pipe 33 is fixedly arranged in the mounting groove 35, one end of the matching pipe 33 penetrates above the door frame 1, and the other end of the matching pipe 33 is a sliding end; the matching block 34 is fixedly arranged at the sliding end of the matching pipe 33, the matching pipe 33 is provided with inert gas, and the two sides of the matching block 34 are provided with second guide inclined surfaces.

[0068] In the embodiment of the present application, the mounting groove 35 and the matching groove 17 are both square-shaped, the mounting groove 35 is vertically arranged on the top of the door frame 1, the matching groove 17 and the mounting groove 35 form a complete channel, the first spring 31 and the closing plate 32 are square-shaped, when the two closing plates 32 are closed, they can just close the matching groove 17. The arrangement of the closing plate 32 does not affect the rotation of the first pulley 221 and the second pulley 222, the matching pipe 33 arranged at one end of the matching groove 17 can be a corrugated pipe or a rubber pipe, which can be elongated or shortened in the matching groove 17. The embodiment of the present application is not limited in this regard. The matching block 34 is triangular-shaped, when the two closing plates 32 are close to each other, the matching block 34 is pushed to slide into the matching groove 17. One end of the closing plate 32 close to each other is provided with an electromagnet, when energized, the electromagnet generates an attractive force, which drives the two closing plates 32 to be close to each other, when de-energized, the electromagnet loses the magnetic force, and the two closing plates 32 are driven by the first spring 31 to slide away from each other.

[0069] In specific use, when the power is off, the electromagnet loses the magnetic force, the first spring 31 has an elastic recovery effect, which drives the two closing plates 32 to pull away from each other, i.e. the matching groove 17 is opened. Since the matching pipe 33 is provided with inert gas, when the closing plate 32 is closed, the matching pipe 33 and the matching block 34 are pressed in the matching groove 17, when the closing plate 32 is opened, the matching pipe 33 is caused to flow due to the inert gas, so that the matching block 34 extends into the matching groove 17, i.e. the matching block 34 extends out of the sliding rail 13, and pushes the door leaf 11 in a direction perpendicular to the sliding rail 13. When the pulley block 22 presses the matching block 34, due to the existence of the second guide inclined surface, the pulley block 22 slides the matching block 34 into the matching groove 17, and the inert gas in the matching pipe 33 enters the driving member 4, so that the driving member 4 drives the door leaf 11 to rotate.

[0070] In combination Figure 5 , in a specific embodiment of the present application, the driving member 4 includes a telescopic plate 41, a mounting rod 42 and a second spring 43.

[0071] In the embodiment of the present application, the telescopic plate 41 is parallel to the slide rail 13, and the length of the telescopic plate 41 is set according to the use. The installation rod 42 is provided to guide the telescopic end of the telescopic plate 41. In specific use, when the matching block 34 is extruded, the inert gas in the matching pipe 33 enters the rodless cavity of the telescopic plate 41, so as to drive the telescopic end of the telescopic plate 41 to elongate, and the telescopic end extrudes the second spring 43 in the process of elongation, so as to compress the second spring 43. When the pulley block 22 slides through the position of the matching groove 17, the matching block 34 is not extruded, the inert gas in the rodless cavity of the telescopic plate 41 flows into the matching pipe 33, the telescopic end of the telescopic plate 41 is not extruded, so that the telescopic end moves to the fixed end of the telescopic plate 41 under the action of the elastic recovery potential of the second spring 43, so as to drive the driving rack 15 to slide under the action of the fixed part, since the driving rack 15 is engaged with the first gear 16, the driving rack 15 drives the first gear 16 to rotate in the process of sliding, the first gear 16 is fixedly connected with the second gear 21, therefore, the first gear 16 drives the second gear 21 to rotate, and the second gear 21 drives the sliding rack 23 to slide in the process of rotating, so as to open the door leaf 11, which is simple and easy to operate.

[0072] In combination with Figure 6 , specifically, the telescopic end of the telescopic plate 41 is vertically provided with a sliding groove 54, one end of the driving rack 15 close to the telescopic plate 41 is vertically provided with an embedded groove 55, and the installation part 5 comprises a telescopic column 51, a sliding block 52 and a third spring 53, one end of the telescopic column 51 is fixedly arranged at the bottom of the sliding groove 54, the sliding block 52 is fixedly arranged at one end of the telescopic column 51 away from the bottom of the sliding groove 54, and the third spring 53 is sleeved on the side of the telescopic column 51, one end of the third spring 53 is fixedly connected with the bottom wall of the sliding groove 54, and the other end of the third spring 53 is fixedly connected with the bottom wall of the sliding block 52, wherein the third spring 53 is used to drive the sliding block 52 to be embedded in the embedded groove 55 when the sliding groove 54 is communicated with the embedded groove 55. One end of the sliding block 52 close to the installation rod 42 is provided with a first guide inclined surface.

[0073] In the embodiment of the present application, the embedded groove 55 and the sliding groove 54 are both arranged in the shape of a rectangle, and a plurality of embedded grooves 55 are arranged along the length direction of the driving rack 15. The specification of the embedded groove 55 can meet the placement of the sliding block 52. The telescopic column 51 and the sliding block 52 can be integrally formed, or can be fixed by welding or bolting, which is not limited in the embodiment of the present application. The common action of the telescopic column 51 and the third spring 53 can ensure the sliding stability of the sliding block 52.

[0074] In specific use, due to the action of the first guide slope, when the telescopic end of the telescopic plate 41 is extended, the sliding block 52 will slide in the sliding groove and cannot be fixed, when the embedded groove 55 is communicated with the sliding groove, the telescopic column 51 and the third spring 53 drive the sliding block 52 to be embedded in the embedded groove 55, so as to realize the fixation of the driving rack 15 and the telescopic end, when the telescopic end is retracted, the side surface of the sliding block 52 is in contact with the embedded groove 55, and the surface of the sliding block 52 in contact with the embedded groove 55 has no guide slope, so under the push of the telescopic end, the sliding block 52 will drive the driving rack 15 to slide along with the retraction of the telescopic end, so as to drive the first gear 16 to rotate, and finally drive the sliding assembly to slide, thereby reducing the problem that the door leaf 11 cannot be opened due to power failure.
