Description

Technical Field

[0001] This invention relates to thermally broken magnetic doors, and more particularly to all-aluminum smart doors. Background Technology

[0002] With economic and social development and the improvement of people's living standards, more and more mid-rise or high-rise buildings are springing up in cities. Since most buildings nowadays are structures with multiple households sharing elevators, the waterproof, heat insulation, and sound insulation performance of the entrance door is even more important. Therefore, thermal break structure is generally used to improve the heat insulation effect of aluminum doors, and anti-collision strips are used to improve the airtightness of the door, so that the entrance door can achieve the effects of heat insulation, sound insulation and fire prevention.

[0003] However, existing entrance doors only lock using a latch after being locked. Since aluminum doors with thermal break structure need to be equipped with anti-collision strips to increase airtightness, the structure that only locks using a latch would greatly increase the pressure on the latch. Therefore, existing technology has introduced magnetic doors, which use an electromagnetic device to generate a magnetic field to make the door panel and door frame firmly adhere to each other, thereby increasing the airtightness of the door.

[0004] The self-closing door formed by the combination of the magnetic attraction structure and the thermal break structure described above can achieve the magnetic attraction function during use, but it cannot achieve self-closing when closing. That is, because it does not have a triggering device, it cannot automatically trigger the electromagnetic device to generate a magnetic field when closing the door. It needs to be used in conjunction with other control devices, which leads to complex structure and increased cost. In addition, the magnetic field generated by the electromagnetic device will disappear when encountering power failure, so using a single magnetic attraction device will lead to locking failure in such cases. Summary of the Invention

[0005] In view of the shortcomings of existing technologies, such as the difficulty in triggering the self-priming of the interrupted bridge insulated self-priming aluminum door and the failure of the electromagnetic device due to power outages, resulting in the failure of the door lock, this invention provides an all-aluminum smart door.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] The all-aluminum smart door includes a door frame and a door leaf hinged to the door frame. Both the door frame and the door leaf have thermal break insulation structures, and anti-collision strips are installed between the door frame and the door leaf for sealing. The door frame and the door leaf are equipped with a magnetic attraction system and a door lock system. The magnetic attraction system includes a magnet installed in the door leaf, an electromagnetic device installed in the door frame, and a control mechanism installed in the door frame. The control mechanism includes a main controller with an external power supply and a pressure sensor connected to the main controller. A hydraulic rod is slidably installed on the door frame. When the door leaf is closed, the outer end of the hydraulic rod is squeezed, causing the inner end of the hydraulic rod to abut against and squeeze the pressure sensor. The sensor transmits the pressure signal to the main controller for comparison with a preset threshold. When the pressure exceeds the preset threshold, the main controller controls the power supply to the electromagnetic device. The electromagnetic device generates a magnetic field that cooperates with the magnet to attract the door leaf and keep it in a normally closed state. The door lock system is a smart lock. The smart lock is electrically or communicatively connected to the main controller. When the smart lock is unlocked, its priority is higher than that of the electromagnetic device. This solution involves installing a hydraulic rod on the door frame. When the door is closed, this rod compresses a pressure sensor, which in turn activates an electromagnetic device to generate a magnetic field that firmly secures the door to the frame. Unlocking is then achieved via a linked smart lock. This dual locking system remains unaffected even during power outages. The smart lock system and the magnetic system work together to lock and unlock the door, ensuring both airtightness and security when locked. The electromagnetic device is an electromagnet.

[0008] Preferably, the intelligent door lock includes a fingerprint and password unlocking module, a power supply, a secondary controller, and a telescopic motor. The fingerprint and password unlocking module, power supply, and telescopic motor are all electrically connected to the secondary controller, which is electrically or communicatively connected to the main controller. The intelligent door lock also includes: a lock body, detachably mounted on the door leaf; a U-shaped switch, mounted on the lock body and electrically connected to the secondary controller; an inner handle, rotatably mounted on the lock body and having an inner shaft extending into the lock body, with a circular turntable on the inner shaft and the inner shaft passing through the circular turntable to form a clutch; a bolt, slidably mounted within the lock body, its inner end passing through the U-shaped switch when retracted; a connecting rod, one end hinged to the inner end of the bolt, the other end eccentrically hinged to the circular turntable; a spring, mounted on the bolt to apply elastic force to extend the bolt out of the door leaf; and an outer handle, which rotates... The mechanism is mounted on the lock body and has an outer shaft extending into the lock body; a sliding ring, which is slidably sleeved on the outer shaft and can rotate with the outer shaft, has a frustum-shaped pressure surface at one end, and a partition is provided in the through hole in the middle; a pressing head, which is located at the end of the telescopic motor push rod and has a frustum-shaped structure, which abuts against the pressure surface of the sliding ring when it extends and drives the sliding ring to slide towards the inner shaft and is sleeved on the clutch part. When sleeved on the clutch part, the inner shaft can rotate with the outer shaft. The pressing head and the end of the motor push rod are fixedly connected or rotatably connected; a return spring, one end of which abuts against the partition and the other end of which abuts against the inner end of the inner shaft for the return of the pressing head; wherein the inner shaft and the sliding ring, and the outer shaft and the sliding ring are connected by mutually matching inner and outer splines or by mutually matching irregular structures. The inner shaft or sliding ring has a guide surface at the short end of its through hole. This guide surface is curved or inclined and guides the sliding ring, making it easier for it to slide and fit onto the inner shaft. For internal unlocking, simply rotate the inner handle to slide the bolt inward. The U-shaped switch receives the signal and transmits it from the secondary controller to the main controller. The main controller then disconnects the power supply to the electromagnetic device, unlocking the lock. For external unlocking, a fingerprint or password controls the telescopic motor. The telescopic motor extends and presses the sliding ring, causing it to fit onto the inner rotating rod. Rotating the outer handle then slides the bolt inward. The U-shaped switch receives the signal and transmits it from the secondary controller to the main controller. The main controller then disconnects the power supply to the electromagnetic device, unlocking the lock.

[0009] Preferably, the cross-section of the irregular structure is elliptical or regular polygonal. This solution provides a smart door lock that uses fingerprint or password in conjunction with a secondary controller to open and close, and then turns the handle to unlock the smart door lock. At the same time, the two controllers work together to cut off the power to the electromagnetic device, thus completing the unlocking of the magnetic attraction system.

[0010] Specifically, a torsion spring is fitted on both the inner and outer shafts, and two mounting posts are provided on the lock body. One end of each torsion spring is curled into a ring structure and fitted onto the two mounting posts respectively. The inner and outer shafts are provided with through holes, and the other ends of the two torsion springs pass through the through holes and are wrapped and fixed or curled into a knot.

[0011] Specifically, the lock body has two 360-degree rotating grooves and two arc-shaped limiting grooves. The limiting grooves are located around the rotating grooves. Both the inner and outer shafts have cylindrical rotating parts, and these rotating parts are respectively placed in the two rotating grooves and rotatably connected to the lock body. Each rotating part has a limiting block, which extends into the two limiting grooves to limit the rotation angle of the inner and outer handles.

[0012] Preferably, the lock body is provided with a groove for sliding the bolt. Both the bolt and the groove are stepped structures. One end of the spring abuts against the step of the bolt, and the other end abuts against the step of the groove to apply an outward sliding force to the bolt. Specifically, the outer end of the bolt is provided with a bevel.

[0013] Specifically, the door panels include a first door panel hinged to the left side of the door frame and a second door panel hinged to the right side of the door frame. The hydraulic rod is located inside the right side of the door frame. Anti-collision strips are provided between the first door panel and the door frame, between the first door panel and the second door panel, and between the second door panel and the door frame. The first door panel has a lock hole for the bolt to extend into.

[0014] Specifically, the first door leaf and the door frame, the first door leaf and the second door leaf, and the second door leaf and the door frame are all equipped with a two-stage step structure that cooperates with each other. An outer anti-collision strip is provided at the corner of the second-stage step of the door frame. The two-stage step structure of the first door leaf has two abutting surfaces that abut against the door frame, and a first inner anti-collision strip and a second inner anti-collision strip are respectively provided on the two abutting surfaces. A third inner anti-collision strip is provided at the corner of the first-stage step on the right side of the first door leaf. The two-stage step structure of the second door leaf has two abutting surfaces that abut against the door frame, and a fourth inner anti-collision strip and a fifth inner anti-collision strip are respectively provided on the two abutting surfaces. The first inner anti-collision strip abuts against the first-stage step of the door frame, the second inner anti-collision strip abuts against the outer anti-collision strip, the third inner anti-collision strip abuts against the fifth inner anti-collision strip, and the fourth inner anti-collision strip abuts against the door frame and the first-stage step of the first door leaf.

[0015] Specifically, both the first and second door panels include a door panel and a surrounding frame that wraps and fixes the door panel around its perimeter. Both the door frame and the surrounding frame are thermally broken structures. The door panel has a multi-layer structure with a mesh-like supporting aluminum frame between each layer.

[0016] Compared with the prior art, the advantages of this invention are as follows: This application sets a hydraulic rod on the door frame to squeeze the pressure sensor when the door is closed. The pressure sensor activates the electromagnetic device to generate a magnetic field that firmly fixes the door leaf to the door frame. Then, it unlocks the door by setting an intelligent door lock. The double locking is not affected even if there is a power outage. The intelligent door lock system and the magnetic attraction system work together to lock and unlock the door, ensuring airtightness and safety when locking. Attached Figure Description

Detailed Implementation

[0028] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of the invention. Example

[0029] All-aluminum smart doors, such as Figure 1-9As shown, the device includes a door frame 10 and a door leaf hinged to the door frame 10. Both the door frame 10 and the door leaf have thermal break structures, and a sealing anti-collision strip is provided between the door frame 10 and the door leaf. A magnetic attraction system and a door lock system are provided within the door frame 10 and the door leaf. The magnetic attraction system includes a magnet installed in the door leaf, an electromagnetic device 50 installed in the door frame 10, and a control mechanism installed in the door frame 10. The control mechanism includes a main controller 60 connected to an external power supply 424 and a pressure sensor 70 connected to the main controller 60. A hydraulic rod 80 is slidably mounted on the door frame 10. The door leaf... When closed, the hydraulic rod 80 is squeezed at its outer end, causing its inner end to press against and compress the pressure sensor 70. The pressure sensor 70 transmits a pressure signal to the main controller 60 for comparison with a preset threshold. If the pressure exceeds the preset threshold, the main controller 60 controls the power supply to the electromagnetic device 50. The electromagnetic device 50 generates a magnetic field that, in conjunction with a magnet, attracts the door leaf and keeps it in a normally closed state. The door lock system is a smart lock 40, which is electrically or communicatively connected to the main controller 60. The smart lock 40 has a higher priority than the electromagnetic device 50 when unlocking. In this solution, a hydraulic rod 80 is installed on the door frame 10 to squeeze the pressure sensor 70 when the door is closed. The pressure sensor 70 activates the electromagnetic device 50 to generate a magnetic field that firmly fixes the door leaf to the door frame 10. Unlocking is then achieved through the linked smart lock 40. This double locking system is unaffected even during power outages. The smart lock 40 system and the magnetic attraction system work together to lock and unlock the door, ensuring both airtightness and security when locked.

[0030] Door lock components:

[0031] like Figure 2-5As shown, the intelligent door lock 40 includes a fingerprint and password unlocking module 423, a power supply 424, a secondary controller 408, and a telescopic motor 409. The fingerprint and password unlocking module 423, the power supply 424, and the telescopic motor 409 are all electrically connected to the secondary controller 408. The secondary controller 408 is electrically or communicatively connected to the main controller 60. The intelligent door lock 40 also includes: a lock body 401, which is detachably mounted on the door leaf; a U-shaped switch 413, which is a photoelectric switch, mounted on the lock body 401 and electrically connected to the secondary controller 408; and an inner handle 421. The lock body 401 is rotatably mounted on the lock body 401 and has an inner shaft 417 extending into the lock body 401. A circular turntable 414 is provided on the inner shaft 417, and the inner shaft 417 passes through the circular turntable 414 to form a clutch part. The latch 402 is slidably mounted inside the lock body 401, and its inner end passes through the U-shaped switch 413 when it retracts. The connecting rod 415 has one end hinged to the inner end of the latch 402 and the other end eccentrically hinged to the circular turntable 414. The spring spring 416 is mounted on the latch 402 to apply spring force to the latch 402. 02.

The inner shaft rod 417 and the sliding ring 411, and the outer shaft rod 404 and the sliding ring 411 are connected by mutually matching inner and outer splines or by mutually matching irregular structures. The short end of the through hole of the inner shaft rod 417 or the sliding ring 411 is provided with a guide surface. The guide surface is a curved surface or an inclined surface. The guide surface is used to guide the sliding ring 411 so that the sliding ring 411 can slide more easily and be sleeved on the inner shaft rod 417.When unlocking from the inside, simply rotate the inner handle 421 to move the bolt 402 inward. The U-shaped switch 413 receives the signal and transmits it from the secondary controller 408 to the main controller 60. The main controller 60 then disconnects the power supply to the electromagnetic device 50 to unlock. When unlocking from the outside, the telescopic motor 409 is controlled by a fingerprint or password.
