Description

Technical Field

[0001] The utility model relates to the technical field of entrance doors, in particular to an entrance door with a low-power consumption broken bridge structure. Background Art

[0002] The entrance door is the first door into the house, also known as the entrance door or main door. It is not only a line of defense for home safety, but also a dividing line between indoor and outdoor environments. In order to ensure the thermal insulation performance of the entrance door, a broken bridge structure is often adopted. By setting up broken bridge aluminum strips, the indoor and outdoor aluminum profiles are separated, thereby effectively blocking the heat conduction path and achieving the purpose of thermal insulation.

[0003] The inventors of this application have found the following problems in practical use:

[0004] The existing broken bridge structure entrance doors currently use a hollow broken bridge structure, so the door panels have low strength and poor safety protection. When used for a long time under conditions of large temperature differences between indoor and outdoor, it is easy to cause slight deformation of the door panels, resulting in gaps between the door panels and the door frame, poor sealing, decreased thermal insulation performance, and even the inability to close. In addition, the hollow broken bridge structure entrance doors have poor safety protection and are easily damaged.

[0005] Therefore, it is necessary to provide a low-power broken bridge structure entrance door to solve the above technical problems. Utility Model Content

[0006] The technical problem to be solved by the present invention is that the existing entrance doors have low strength, poor safety protection, easy deformation resulting in poor sealing and reduced thermal insulation performance. In view of the above-mentioned defects of the existing technology, a low-power broken bridge structure entrance door is provided.

[0007] To achieve the above-mentioned object, the technical solution of the present invention is: a low-power thermal break structure entrance door, comprising a frame, a door panel, a first thermal break panel and a second thermal break panel, wherein a frame groove is provided inside the frame, a first sealing strip is provided on the outer surface of the frame groove, and a second sealing strip is provided on the bottom of the door panel;

[0008] An aluminum frame is provided inside the first and second broken bridge plates, and the interior of the aluminum frame is filled with a first and second heat insulation board, and the first and second heat insulation boards are alternately arranged longitudinally inside the door panel through a separation board;

[0009] The frame is rotatably connected to the first broken bridge plate through a hinge. A lock core is provided on one side of the first broken bridge plate. A permanent magnet is provided on the outer surface of the lock core. A lock slot is provided on the inner wall of the frame. A Hall sensor is provided inside the lock slot.

[0011] It is further provided that the first insulation board and the second insulation board are arranged in a triangular shape, the first insulation board is made of polyurethane, and the second insulation board is made of perlite.

[0012] By adopting the above technical solution, polyurethane is a highly efficient thermal insulation material with low thermal conductivity, which can effectively prevent the transfer of heat, significantly improve the thermal insulation performance of the door, reduce heat exchange between indoors and outdoors, and thus reduce energy consumption.

[0013] It is further provided that an arc-shaped groove is provided on the outer surface of the first sealing strip; an arc-shaped chamfer is provided on the outer surface of the second sealing strip, and the arc-shaped groove and the arc-shaped chamfer are matched with each other.

[0014] By adopting the above technical solution, the arc-shaped groove enables the first sealing strip to form a tighter fitting surface when combined with the second sealing strip, which helps to reduce the penetration of air, moisture and dust, thereby significantly improving the sealing performance of the entrance door.

[0015] It is further provided that the first sealing strip and the second sealing strip are made of EPDM material, and the isolation plate is made of aluminum silicate fiber material.

[0016] By adopting the above technical solutions, EPDM has excellent weather resistance and can maintain stable performance in various harsh environments, such as resisting erosion by ultraviolet radiation, acid rain, seawater, etc., ensuring the long-term effectiveness of the sealing strip and extending its service life.

[0017] It is further provided that the model of the Hall sensor is InAs-stable, and the Hall sensor is adapted to the permanent magnet.

[0018] By adopting the above technical solution, the InAs-stable Hall sensor usually has high measurement accuracy and stability, and can accurately sense the changes in the magnetic field generated by the permanent magnet, thereby ensuring that the switch state of the door lock is precisely controlled.

[0019] It is further provided that a handle is provided on the outer surface of the door panel, a rubber layer is provided on the outer surface of the handle, and friction lines are provided on the outer surface of the rubber layer.

[0020] By adopting the above technical solution, the handle is the most common operating component on the entrance door. It provides users with an intuitive and convenient way to open the door, allowing users to easily open or close the door.

[0021] It is further provided that a display screen is provided above the handle, and a password button and a camera are provided on the outer surface of the display screen.

[0022] By adopting the above technical solution, the camera can monitor the dynamics in front of the door in real time, and users can remotely view the scene in front of the door through mobile phone APP to find out whether there are visitors or abnormal situations.

[0023] Compared with related technologies, the low-power thermal break structure entrance door provided by the present invention has the following beneficial effects:

[0024] The utility model provides a low-power broken bridge structure entrance door, which effectively blocks the thermal bridge effect by arranging a first broken bridge plate, a second broken bridge plate, an isolation plate and an aluminum frame, and significantly improves the thermal insulation performance of the entrance door. The alternating arrangement of the isolation plates further enhances the thermal insulation effect, and the first and second broken bridge plates of the triangle fill the aluminum frame to provide good support and strength, thereby ensuring the structural stability and durability of the door and enhancing the safety of the entrance door. The arrangement of the sealing strip effectively prevents the penetration of air, dust and moisture, enhances the sealing performance of the door, and further improves the thermal insulation performance of the entrance door.

[0025] The utility model provides a low-power thermal break structure entrance door, which adopts a Hall sensor and a permanent magnet to improve the convenience of use and make the entrance door have higher security performance. When the door is illegally opened or attempted to be opened, the Hall sensor can immediately sense and send an alarm signal.

[0032] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.

[0033] Example 1:

[0034] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, a low-power thermal break structure entrance door of the present invention includes a frame 1, a door panel 3, a first thermal break panel 8 and a second thermal break panel 9. A frame groove 2 is provided inside the frame 1, a first sealing strip 6 is provided on the outer surface of the frame groove 2, and a second sealing strip 7 is provided on the bottom of the door panel 3.

[0035] An aluminum frame 10 is provided inside the first broken bridge plate 8 and the second broken bridge plate 9, and the interior of the aluminum frame 10 is filled with a first heat insulation board 11 and a second heat insulation board 12. The first heat insulation board 11 and the second heat insulation board 12 are longitudinally alternately arranged inside the door panel 3 through a separation board 16;

[0036] The frame 1 is rotatably connected to the first broken bridge plate 8 through a hinge 17. A lock core 5 is provided on one side of the first broken bridge plate 8. A permanent magnet 14 is provided on the outer surface of the lock core 5. A lock slot 13 is provided on the inner wall of the frame 1. A Hall sensor 15 is provided inside the lock slot 13. The aluminum frame 10 serves as a supporting structure inside the first broken bridge plate 8 and the second broken bridge plate 9. It is light and strong and can withstand greater pressure and impact. The hinge 17, as a component connecting the frame 1 and the first broken bridge plate 8, needs to have good load-bearing capacity and rotation flexibility.

[0037] like Figure 2 、 Figure 3 、 Figure 5As shown, the first insulation board 11 and the second insulation board 12 are arranged in a triangular shape. The first insulation board 11 is made of polyurethane and the second insulation board 12 is made of perlite. Polyurethane is a highly efficient thermal insulation material with low thermal conductivity, which can effectively prevent the transfer of heat, significantly improve the thermal insulation performance of the door, reduce the heat exchange between indoor and outdoor, and thus reduce energy consumption. Perlite is a porous inorganic material with extremely low thermal conductivity and excellent thermal insulation performance. In the low-power broken bridge structure entrance door, the second insulation board 12 made of perlite can further enhance the thermal insulation effect of the door and improve energy utilization efficiency.

[0038] like Figure 1 As shown, the outer surface of the first sealing strip 6 is provided with an arc-shaped groove; the outer surface of the second sealing strip 7 is provided with an arc-shaped chamfer, and the arc-shaped groove and the arc-shaped chamfer fit together. The arc-shaped groove enables the first sealing strip 6 to form a tighter fitting surface when combined with the second sealing strip 7, which helps to reduce the penetration of air, moisture and dust, thereby significantly improving the sealing performance of the entrance door. The first sealing strip 6 and the second sealing strip 7 play a role in buffering and shock absorption when closing the door, reducing the direct impact force, thereby reducing the noise caused by the impact.

[0039] like Figure 1 As shown, the first sealing strip 6 and the second sealing strip 7 are made of EPDM material, and the isolation plate 16 is made of aluminum silicate fiber material. EPDM has excellent weather resistance and can maintain stable performance in various harsh environments, such as resisting erosion by ultraviolet radiation, acid rain, seawater, etc., ensuring that the sealing strip is effective for a long time and extending its service life. The thermal conductivity of aluminum silicate fiber is low, which can effectively reduce heat transfer, improve the thermal insulation performance of the entrance door, and reduce energy consumption. The material is light, but has high strength and toughness, and can withstand certain mechanical shocks and vibrations.

[0040] like Figure 2 As shown, the model of the Hall sensor 15 is InAs-stable. The Hall sensor 15 is compatible with the permanent magnet 14. The InAs-stable model Hall sensor 15 usually has high measurement accuracy and stability, and can accurately sense the changes in the magnetic field generated by the permanent magnet 14, thereby ensuring that the switch state of the door lock is accurately controlled. The permanent magnet 14 can generate a magnetic field without an external power supply, reducing the complexity and energy consumption of the system.

[0041] like Figure 1As shown, a handle 4 is provided on the outer surface of the door panel 3, and a rubber layer is provided on the outer surface of the handle 4. The outer surface of the rubber layer is provided with friction patterns. The handle 4 is the most common operating component on the entrance door. It provides the user with an intuitive and convenient way to open the door, allowing the user to easily open or close the door. The rubber layer has good anti-slip properties. Even in a humid or rainy environment, the user can hold the handle stably to avoid slipping.

[0042] like Figure 1 As shown, a display screen 18 is provided above the handle 4, and a password button and a camera are provided on the outer surface of the display screen 18. The camera can monitor the dynamics in front of the door in real time. The user can remotely view the picture in front of the door through a mobile phone APP to find out whether there are visitors or abnormal situations. The password button allows the user to enter a customized password to unlock the door lock. Compared with traditional mechanical keys, the password is more difficult to copy and crack, thereby improving the security of the door lock.

[0043] During implementation, first, the first heat insulation board 11 and the second heat insulation board 12 in the aluminum frame 10 are staggered, and the upper and lower first heat insulation boards 11 and the second heat insulation boards 12 are also staggered. When heat is transferred, the horizontal and vertical directions are isolated by multiple layers of thermal bridges. When the door is closed, the arc grooves and arc chamfers of the first sealing strip 6 and the second sealing strip 7 fill the gap between the door panel 3 and the frame groove 2. When the handle 4 is turned, the permanent magnet 14 moves with the lock core 5 to change the magnetic field. The Hall sensor 15 detects the change in the magnetic field and sends an electrical signal to an external controller such as the user's mobile phone for prompting.

[0044] The advantages of this technical solution in practical applications include but are not limited to the following:

[0045] 1. The first and second broken bridge boards provide good support and strength for the aluminum frame, ensuring the structural stability and durability of the door, enhancing the safety of the entrance door, and improving the thermal insulation performance of the entrance door;

[0046] 2. Hall sensor and permanent magnet: When the door is illegally opened or attempted to be opened, the Hall sensor can instantly sense and send an alarm signal.

[0047] Although the 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 may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
