[0002] At present, the opening and closing of the sliding and lifting doors on the market usually rely on manually turning the handle to lift or lower the door leaf. In the case of manual operation, traditional door leaves often require greater force to open or close, especially for heavier or larger door leaves. Turning the handle requires greater force, or the handle turns at a greater angle, which increases the difficulty of operation for users. In addition, sliding and lifting doors are generally heavy sliding doors. It is often difficult for the door leaf to stop accurately at any position during the sliding process. Especially at a certain speed, due to inertia, the door leaf may continue to slide for a distance before stopping, which not only affects the user experience, but may also cause accidental injuries or other safety accidents.

[0003] In order to solve the above problems and improve the safety and convenience of door leaf operation, the present invention proposes an improved design. Compared with the prior art, this embodiment aims to provide a simpler and safer door leaf and operation method, making the lifting or pressing operation of the door leaf easier and more convenient, allowing users to get started faster, and being able to stop the door leaf in time at any position during the sliding process, effectively avoiding potential risks caused by failure to stop in time during the sliding process.

The door leaf 2 can slide in the door frame 1, and can be locked with the door frame 1 at a position where the sliding stops; wherein the handle can control the lifting mechanism, and the lifting mechanism is electrically driven to lift or lower the door leaf 2 relative to the door frame 1, when the door leaf 2 is lifted, the door leaf 2 can slide in the door frame 1; when the door leaf 2 is lowered, the door leaf 2 is pressed on the door frame 1 and locked to the door frame 1, and the door leaf 2 is pressed down on the door frame 1, and the door leaf 2 and the door frame 1 are locked by the gravity of the door leaf 2 itself and the friction between the two. The lifting and lowering of the door leaf 2 can be achieved through a mechanical lifting method. After the door leaf 2 is lifted, it abuts against the door frame 1 through the sliding wheel 3, so that the door leaf 2 can slide in the door frame 1; or the lifting of the door leaf 2 can be achieved through electromagnetic suspension. In the lifted state, the door leaf 2 and the door frame 1 remain in a suspended state, and the door leaf 2 can be moved in the door frame 1 by pulling.

[0030] Instructions for use: When the control switch of the handle is activated, the door leaf 2 makes a lifting movement relative to the door frame 1. At this time, the handle can be pulled to make the door leaf 2 slide in the door frame 1; when the door leaf 2 slides to the desired position, the control switch of the handle is turned off, and the door leaf 2 is pressed down on the door frame 1 and locked.

[0031] Compared with the prior art, the lifting or pressing down operation of the door leaf 2 in this embodiment is more convenient and easier for users to use. Moreover, the door leaf 2 can stop in time at any position during the sliding process, avoiding accidents caused by inertial sliding that cannot be stopped in time.

[0032] In some embodiments, the handle is a touch handle 4, the touch handle 4 is electrically connected to the lifting mechanism, and the lifting mechanism can be controlled by touching the touch handle 4. The touch handle 4 has a stylish appearance and is easier to control the switch state.

[0033] In some embodiments, the door leaf 2 can stop sliding at any position during the sliding process, and when stopped, it is locked with the door frame 1. Specifically, when the touch handle 4 is held, the switch of the handle is in the start state, so that the door leaf 2 is lifted and held; when the touch handle 4 is released, the switch of the handle is in the close state, so that the door leaf 2 is pressed down and locked to the door frame 1 by its own gravity.

[0034] In some embodiments, the lifting mechanism includes a driving motor 5 and a lifting slide member, the driving motor 5 drives the lifting slide member through a transmission mechanism, so that the door leaf 2 can be lifted or lowered relative to the door frame 1, and the transmission mechanism can be at least one of a gear, a chain, and a belt. In addition, the lifting slide member is provided with a sliding wheel 3, and when the door leaf 2 is lifted relative to the door frame 1, the sliding wheel 3 abuts against the door frame 1.

[0035] In some embodiments, the lifting and sliding member includes a plurality of connecting arms 6 arranged along the bottom of the door leaf 2. The connecting arms 6 are rotatably connected to the inside of the door leaf 2 respectively. The rotating shaft connecting the connecting arm 6 and the door leaf 2 is arranged in the middle of the connecting arm 6. The sliding wheel 3 is rotatably connected below the connecting arm 6. The upper ends of the plurality of connecting arms 6 are linkedly connected with a push plate 7, and the driving motor 5 can make the push plate 7 move back and forth along the length direction of the push plate 7, and pushing the push plate 7 can make the connecting arm 6 swing up or down, thereby realizing the lifting and pressing down of the door leaf 2.

[0036] In some embodiments, the driving motor 5 is arranged at the middle position of the bottom of the door leaf 2, and the shaft of the driving motor 5 is connected to a screw rod 8, and the screw rod 8 is connected to an inverted trapezoidal slider 9. When the screw rod 8 rotates, the slider 9 can only move in the direction of the screw rod 8 and cannot rotate relative to the door leaf 2. There are two push plates 7, and the push plates 7 are respectively arranged on both sides of the slider 9. When the slider 9 moves, it can drive the push plates 7 to move outward on both sides of the driving motor 5 or move in the direction of the driving motor 5, and the connecting arms 6 arranged on both sides of the driving motor 5 have opposite rotation directions when they swing up or down. The connecting arms 6 with opposite rotation directions are designed on both sides of the driving motor 5, which can offset the lateral thrust generated during the rotation of the connecting arms 6, so that the lateral displacement of the door leaf 2 during the lifting and pressing process is smaller.

[0037] In some embodiments, a power generation device 10 and a power supply battery 11 are provided inside the door leaf 2. The rotor of the power generation device 10 is connected to the sliding wheel 3 through a transmission mechanism. In this embodiment, the transmission mechanism is a synchronous belt 12. The power generation device 10 is electrically connected to the power supply battery 11, and the power supply battery 11 supplies power to the drive motor 5. The power supply battery 11 can be set to be replaceable. An opening and a cover plate can be set on the surface of the door leaf 2. The cover plate is detachably sealed on the opening. When the power supply battery 11 needs to be replaced, the cover plate can be opened for replacement. A wireless charging device can also be provided between the door leaf 2 and the door frame 1, preferably between the door leaf 2 and the door frame 1 when in the closed position of this embodiment. When this embodiment is in the closed position, the wireless charging device is started to charge the power supply battery 11.

[0038] The generator 10 is arranged on the connecting arm 6, and the rotor of the generator 10 is connected to the sliding wheel 3 through a transmission mechanism, and the transmission mechanism can be at least one of a gear, a belt, and a chain. When the window sash slides in the window frame, the rotation of the sliding wheel 3 can drive the rotor to rotate, so that the generator 10 generates electricity and charges the power supply battery 11.

[0039] The power generation device 10 is provided with an output circuit switch. When the sliding speed of the door leaf 2 is less than 30 cm / s, the output circuit switch can be controlled to be disconnected, and the power generation device 10 does not work; when the sliding speed of the door leaf 2 is greater than or equal to 30 cm / s, the output circuit switch can be controlled to be closed, and the power generation device 10 works to generate electricity. At the same time, the power generation device 10 can form a certain resistance to the sliding wheel 3, reduce the sliding speed of the door leaf 2, and prevent the door leaf 2 from moving too fast. The sliding speed of the door leaf 2 can be obtained by the speed sensor set on the sliding wheel 3. This embodiment can prevent the door leaf 2 from sliding too fast, and can also recover kinetic energy, so that this embodiment can operate for a long time only by the power of the power supply battery 11.

[0040] In some embodiments, an anti-collision block 13 is provided on the side of the door leaf 2 away from the handle, and the anti-collision block 13 can move toward the direction of the door leaf 2 and can be reset. A second generator 14 is provided inside the door leaf 2, and the second generator 14 is electrically connected to the power supply battery 11. The rotor of the second generator 14 is connected to the anti-collision block 13 through a one-way transmission mechanism, and the one-way transmission mechanism can be realized by the cooperation of a bevel gear 16 and a bevel rack 15, and the bevel gear 16 is connected to the rotor of the second generator 14 through a transmission mechanism. The bevel rack 15 is provided on the anti-collision block 13, and the bevel rack 15 is slidably connected to the inside of the door leaf 2. When the anti-collision block 13 slides toward the direction of the door leaf 2, the anti-collision block 13 can drive the rotor of the second generator 14 to rotate, and when the anti-collision block 13 is reset, the anti-collision block 13 does not affect the rotation state of the rotor. An elastic member 17 is provided between the anti-collision block 13 and the door leaf 2, so that the anti-collision block 13 maintains a movement tendency to move outward from the door leaf 2. The anti-collision block 13 can play the role of impact buffering and can also recycle and charge kinetic energy.

[0041] Reference Figures 1 to 4 , a control method for a push-pull lifting door:

[0042] S1. When the door leaf 2 needs to be opened, the control switch of the handle is activated, the lifting mechanism lifts the door leaf 2 relative to the door frame 1, and the door leaf 2 is pulled to slide in the door frame 1;

[0043] S2. During the sliding process, the power generation device in the door leaf 2 can absorb the kinetic energy of the door leaf 2 during the movement process to charge the power supply battery 11;

[0044] S3. When the door leaf 2 slides to any desired position, the control switch of the handle is turned off, and the lifting mechanism causes the door leaf 2 to descend relative to the door frame 1. The door leaf 2 is pressed against the door frame 1 and locked to the door frame 1.

[0045] In some embodiments, during the sliding process, when the sliding speed of the door leaf 2 is greater than or equal to a preset value, the power generation device 10 is started to recover kinetic energy to charge the battery; when the sliding speed of the door leaf 2 is less than the preset value, the power generation device 10 turns off the power generation function.

[0046] In this embodiment, the preset value of the sliding speed of the door leaf 2 is set to 30 cm / s. When the sliding speed of the door leaf 2 is greater than or equal to 30 cm / s, the output switch of the power generation device 10 is closed to recover kinetic energy to charge the battery. At the same time, the power generation device 10 can form a certain resistance to the sliding wheel 3, thereby reducing the sliding speed of the door leaf 2 and preventing the door leaf 2 from moving too fast.
