Multi-segment lifting doors on the market have poor sealing, low speed, and require a large space at the top. Top-mounted doors on the market have low speed, and all door panels separate simultaneously when rising, resulting in slow opening speed, poor security, and a high risk of door panels falling. Airports, shipyards, mines, maintenance workshops of large industrial automated plants, and garages all require a highly stable intelligent door to address the shortcomings of existing intelligent door technologies. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a top-section vertical lifting smart door.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-14 The present invention provides a technical solution:

[0033] A top-section vertical lifting smart door includes several door panels 30, with door legs 10 on both sides of each door panel 30. Door panel guide wheels 31 are provided on both sides of each door panel 30. One end of each door panel guide wheel 31 is inserted into the door panel, and the axis of the door panel guide wheel 31 is on the side of the door panel 30 away from the door head. This allows the door panel 30 to tilt towards the wall under the drive of the synchronous belt 29, so that the door panel 30 slides down the track 27 after closely following the guide wheel, avoiding the door panel from getting caught on the front track entrance. The other end of the door panel guide wheel 31 is fixed on the synchronous belt 29, and the guide wheel slides on the track groove. The door panel 30 is located in the middle of the conveying mechanism, which drives the door panel by chain drive. Lifting mechanisms are provided on both sides of the door panel for lifting the door panel 30.

[0034] The door panel 30 is located in the middle of the conveying mechanism, which drives the door panel 30 by chain drive. The conveying mechanism is equipped with symmetrically arranged door legs 10, which are divided into upper and lower parts, namely door leg part one and door leg part two. Door leg part one and door leg part two are integrally formed. Door leg part two has a motor fixing frame 15 on one side and a groove on the other side for fixing the top drive shaft 3. The space formed by door leg part two is used to accommodate the lifting mechanism. The motor fixing frame 15 is fixedly installed at the top of the door leg 10. The motor 1 is installed on the lower side of the surface of the motor fixing frame 15. The motor drive main sprocket 6 is mounted on the motor shaft of the motor 1. The motor drive secondary sprocket 7 is arranged above the motor drive main sprocket 6. The motor drive chain 2 is sleeved between the motor drive main sprocket 6 and the motor drive secondary sprocket 7. The top drive shaft 3 is sleeved inside the motor drive secondary sprocket 7. The fixed bearing 12 is installed between the top drive shaft 3 and the motor fixing frame 15. The lifting mechanism is mounted on the top drive shaft 3. Using a chain drive, the chain is connected and fixed to the bottommost door panel. Driven by the chain, the bottommost door panel moves all the upper door panels upwards.

[0035] The lifting mechanism includes a top drive sprocket 8 and a bottom sprocket 9. A bottom sprocket bracket 5 is fitted around the bottom sprocket 9. A door lifting chain 4 is fitted between the top drive sprocket 8 and the bottom sprocket 9. The door lifting chain 4 is located inside the door leg 10. A gear fixing plate 24 is installed on the top side of the door leg 10. A main gear 18 and a secondary gear 19 are installed inside the gear fixing plate 24. A synchronous pulley 20 is installed on the end face of the secondary gear 19. A secondary bearing 14 is installed between the main gear 18 and the secondary gear 19 and the gear fixing plate 24. A guide wheel rear track 27 is fitted inside the door leg 10.

[0036] The door panel storage structure is used to store the door panel after it is lifted. Internally, it includes a top storage plate 28. A synchronous belt 29 connects the door panel guide wheels 31, indirectly connecting several door panels 30 together. The door panels 30 are positioned between the top storage plates 28 on both sides. A buffer rubber plate 33 is installed at the bottom of the top storage plate 28. A track seal 37 is installed between the top storage plate 28 and the door panel 30. The door panel guide wheels 31 are positioned on both sides of the door panel 30, and are positioned so that they engage with the top storage plate 28. A top pressure plate 22 is provided on the synchronous belt pulley 20 to prevent the guide wheels from... The top derails from the track, while simultaneously guiding the guide wheel smoothly into the vertical track. This prevents the top of the door panel guide wheel 31 from derailing and ensures that the door panel guide wheel 31 is smoothly guided into the vertical track. The top drive shaft 3 and the rotating shaft of the drive synchronous belt pulley 20 are driven by gears. The gear meshing causes the synchronous belt pulley 20 to rotate in the opposite direction to the top drive shaft 3, thus achieving the reciprocating motion of the chain and the unidirectional operation of the synchronous belt 29. This allows the door panels to finally stack on the horizontal guide rail of the top door head. Conversely, when the door panel 30 falls, the reciprocating motion of the chain brings the bottom door panel 30 to the ground, and the remaining door panels 30 fall separately under the speed limiting of the synchronous belt pulley 20 and the action of gravity.

[0037] The door panel 30 is fitted with the guide wheel rear track 27, and the door panel 30 is designed to be stacked.

[0038] The outer surface of the buffer plate 33 is made of silicone material, and the track seal 37 is made of rubber material.

[0039] The radius of the main gear 18 is R3, the radius of the secondary gear 19 is R4, the radius of the synchronous belt pulley 20 is R5, the radius of the top transmission sprocket 8 is R2, the height of the door panel 30 is H, and the tooth pitch of the synchronous belt 29 at the door panel mounting position is L. Figure 14 As shown, where, There is a certain numerical ratio between the door panel height H and the tooth pitch L of the synchronous belt clamping the door panel. This allows the top door panel in the slide to be pulled up by the synchronous belt first and move towards the door head under the drive of the synchronous belt. This process continues until all the door panels except the bottom one and the chain-connected door panels are stacked on the top door head horizontal guide rail. After the last bottom door panel connected by the synchronous belt, a length longer than the tooth pitch L of the clamping door panel is still reserved.

[0040] Meanwhile, a buffer rubber plate 33 is designed on the door head. The buffer rubber plate 33 is installed on the storage plate 28 on the top of the door panel. When the door panels 30 are stacked in the door head, the buffer rubber plate 33 reduces the shaking of the door panels 30 and achieves smooth operation.

[0041] The smart door can be controlled remotely, and to increase indoor lighting, translucent glass can be installed on the door.

[0042] Working principle: When the vertical lifting intelligent door is activated, the motor drives the sprocket, which in turn drives the top drive shaft via a chain. The top drive shaft is equipped with a drive sprocket and a transmission sprocket. The chain runs and is fixed to the bottom door panel. Driven by the chain, the bottom door panel connects to the remaining door panels via a synchronous belt. The top drive shaft and the shaft driving the synchronous belt pulley are connected by gears. The gear meshing causes the synchronous belt pulley to rotate in the opposite direction to the top drive shaft, thus achieving reciprocating motion of the chain and unidirectional movement of the synchronous belt. This results in the door panels ultimately stacking on the horizontal guide rail at the top of the door. The height of the door panels and the installation of the synchronous belt... The tooth pitch of the door panels has a specific ratio calculation relationship, which ensures that the top door panel in the slide is pulled up first by the synchronous belt and moves towards the door head under the drive of the synchronous belt. This process continues until all the door panels except the bottom one connected to the chain are stacked on the top horizontal guide rail. This allows all the top door panels to move upwards. The top drive shaft and the shaft driving the synchronous belt pulley are driven by gears. The gear meshing causes the synchronous belt pulley to rotate in the opposite direction to the top drive shaft, thus achieving the reciprocating motion of the chain and the unidirectional movement of the synchronous belt, so that the door panels are finally stacked on the top horizontal guide rail. Conversely, when the door panels fall, the reciprocating motion of the chain brings the bottom door panel to the ground, and the remaining door panels fall into the track under the speed limiting of the synchronous belt pulley and the action of gravity.

[0043] In some special cases, the required manual pulling force can be calculated based on the weight of the door panel. A torsion spring is fixed below the top drive shaft via a drive shaft. When the door loses power, the motor brake is released, and the door can be opened manually or with the help of small equipment to push and pull.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
