Description

Technical Field

[0001] This invention relates to the field of equipment control, and more particularly to a door opening structure and automated equipment. Background Technology

[0002] In recent years, with the continuous development of industrialization, more and more automated equipment has emerged to accelerate industrial production and improve the quality of life. For these automated equipment, it is necessary to design door opening structures for frequently maintained positions or human-machine interaction positions to facilitate equipment maintenance or personnel operation.

[0003] Common door opening methods mostly employ hinges or sliding rails to achieve a rotating opening mechanism, or use hinged doors that open vertically or horizontally. For hinged doors, because traditional door panels are rigid and cannot be extended or folded, sufficient space must be reserved in the design to accommodate the door panel. This results in a larger overall size of the door structure in the opening direction, making traditional rigid hinged doors unsuitable when space is limited. Traditional rotating doors are often flexible doors such as roller shutters, and are mostly suitable for vertical use, unable to meet the needs of horizontal use. In practical applications where space constraints necessitate the use of horizontal hinged doors, the aforementioned traditional hinged door or flexible door structures are no longer applicable, leaving these problems unresolved. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this application provides a door opening structure and an automated device.

[0005] This application provides a door opening structure, disposed on a door panel and side panel with an opening, including a drive assembly, a transmission pair, a steering assembly, and a flexible door assembly. The transmission pair includes a transmission belt and multiple transmission wheels, which are rotatably disposed on the door panel and the side panel respectively. The transmission belt is sleeved on the multiple transmission wheels. The drive assembly is used to drive the transmission wheels to rotate. The steering assembly includes a steering seat and a steering wheel. The steering seat is disposed at the connection between the side panel and the door panel. The steering wheel is rotatably disposed on the steering seat. The steering wheel abuts against the transmission belt to change the direction of movement of the transmission belt. The flexible door assembly includes multiple connectors and door panels. The multiple connectors are sequentially disposed on the transmission belt along its length direction. The door panels are disposed on the connectors along a direction perpendicular to the movement of the transmission belt, and the multiple door panels correspond to the multiple connectors respectively.

[0031] Example 1

[0032] Please see Figure 1 One embodiment of this application provides a door opening structure 100, which is installed at a location where a door needs to be opened and closed, such as in an automated device. The door opening structure 100 is used to solve the problem of needing a horizontally opening door but having limited space to open it.

[0033] The door opening structure 100 is provided on the door frame 200. The door frame 200 includes a door panel 201 and a side panel 202. An opening 203 is provided on the door panel 201. The door opening structure 100 is used to open and close the opening 203.

[0034] The door panel 201 is connected to the side panel 202, and the side panel 202 and the door panel 201 are not in the same plane.

[0035] In some embodiments, the angle between the side panel 202 and the door panel 201 is less than or equal to 90 degrees. Preferably, the side panel 202 is perpendicular to the door panel 201.

[0036] For details, please refer to Figure 2 The door opening structure 100 includes a drive assembly 10, a transmission assembly 20, a steering assembly 30, and a flexible door assembly 40. The drive assembly 10 is mounted on the side panel 202. The transmission assembly 20 is movably mounted on the door panel 201 and the side panel 202, and connected to the drive end of the drive assembly 10. The steering assembly 30 is located at the connection between the side panel 202 and the door panel 201. The steering assembly 30 is used to change the direction of movement of the transmission assembly 20. The flexible door assembly 40 is mounted on the transmission assembly 20. The drive assembly 10 can drive the transmission assembly 20 to move, thereby moving the flexible door assembly 40 mounted on the transmission assembly 20 to the opening 203 for closing, or away from the opening 203 for opening. The steering assembly 30 allows the flexible door assembly 40 mounted on the transmission assembly 20 to move to the side panel 202 when away from the door panel 201.

[0037] The drive assembly 10 includes a drive member 11, a drive wheel 12, a driven wheel 13, a drive shaft 14, and a drive belt 15. The drive member 11 is mounted on the side plate 202. The drive wheel 12 is connected to the drive end of the drive member 11. The drive shaft 14 is rotatably mounted on the side plate 202 and is vertically oriented. The driven wheel 13 is mounted on the drive shaft 14. The drive belt 15 is sleeved on the drive wheel 12 and the driven wheel 13, enabling a transmission connection between them. The transmission assembly 20 is connected to the drive shaft 14. The drive member 11 can drive the drive wheel 12 to rotate, thereby causing the drive belt 15 to drive the driven wheel 13 to rotate. The rotating driven wheel 13, in turn, drives the drive shaft 14 to rotate, thereby driving the transmission assembly 20 to move.

[0038] In some embodiments, the drive element 11 is a motor. Preferably, the drive element 11 is a servo motor to precisely control the door opening size and opening speed, etc.

[0039] In some embodiments, the drive element 11 is fixedly mounted on the side plate 202 via a mounting base 111.

[0040] In some embodiments, the drive wheel 12 and driven wheel 13 are sprockets, and the drive belt 15 is a transmission chain. The drive wheel 12, driven wheel 13, and drive belt 15 cooperate to improve control accuracy and achieve high transmission speed. The drive belt 15 may also employ other transmission methods such as belt drive or rope drive.

[0041] In some embodiments, the drive wheel 12, driven wheel 13 and drive belt 15 can be removed, and the drive member 11 is directly connected to the drive shaft 14, thereby reducing the number of components used.

[0042] In some embodiments, the drive shaft 14 is rotatably mounted on the side plate 202 via a bearing 141.

[0043] Specifically, the side plate 202 is provided with two bearings 141. The two bearings 141 are arranged opposite to each other. The two ends of the drive shaft 14 are respectively rotatably disposed in the corresponding bearings 141.

[0044] The transmission assembly 20 includes two sets of transmission pairs 21. The two sets of transmission pairs 21 are rotatably mounted on the door panel 201 and the side panel 202, respectively, and are arranged opposite to each other. The two sides of the flexible door assembly 40 are respectively connected to the corresponding transmission pairs 21.

[0045] Specifically, the transmission pair 21 includes a transmission belt 211 and a plurality of transmission pulleys 212. The plurality of transmission pulleys 212 are respectively rotatably mounted on the door panel 201 and the side panel 202. The transmission belt 211 is sleeved on the plurality of transmission pulleys 212.

[0046] In each group of transmission pairs 21, one transmission wheel 212 is mounted on the drive shaft 14 and rotates with the rotation of the drive shaft 14. At least one transmission wheel 212 in each group of transmission pairs 21 is mounted on the door panel 201 and is located on the side of the opening 203 away from the side panel 202.

[0047] Preferably, two sets of transmission wheels 212 in the transmission pair 21 are respectively provided at both ends of the drive shaft 14.

[0048] In some embodiments, the transmission wheel 212 is also a sprocket, and the transmission belt 211 is also a transmission chain, so that the matching accuracy between the transmission wheel 212 and the transmission belt 211 is higher, and the transmission speed is higher. The transmission belt 211 may also adopt other transmission methods such as belt drive or rope drive.

[0049] In some embodiments, the transmission assembly 20 further includes a synchronous shaft 22. The synchronous shaft 22 is connected to two transmission wheels 212 disposed opposite to each other in the two sets of transmission pairs 21, thereby enabling the two sets of transmission pairs 21 to rotate more precisely in sync.

[0050] In some embodiments, the synchronous shaft 22 is rotatably mounted on the door panel 201 and located on the side of the opening 203 away from the side panel 202. The two transmission wheels 212 furthest from the steering assembly 30 in the two sets of transmission pairs 21 are respectively located at both ends of the synchronous shaft 22.

[0051] In some embodiments, the synchronous shaft 22 is rotatably mounted on the door panel 201 via a bearing.

[0052] The steering assembly 30 includes a steering seat 31 and a steering wheel 32. The steering seat 31 is located at the connection between the side panel 202 and the door panel 201. The steering wheel 32 is rotatably mounted on the steering seat 31. The steering wheel 32 engages with the transmission belt 211 at the point where the transmission belt 211 needs to turn, so that the direction of movement of the transmission belt 211 changes after passing the steering wheel 32. The steering wheel 32 can also tension the transmission belt 211.

[0053] Specifically, each transmission pair 21 has two steering wheels 32 on its transmission belt 211 to change the direction of movement of the transmission belt 211.

[0054] In some embodiments, the steering seat 31 is located on the side of the side panel 202 near the door panel 201.

[0055] In some embodiments, the steering assembly 30 further includes a steering shaft 33. The steering shaft 33 is disposed on the steering seat 31. The steering wheel 32 is rotatably disposed on the steering shaft 33.

[0056] In some embodiments, the steering wheel 32 is also a sprocket to improve the fit between it and the drive belt 211.

[0057] Please also refer to Figure 3 The flexible door assembly 40 includes multiple connectors 41 and door panels 42. The multiple connectors 41 are arranged sequentially along the length of the transmission belt 211, and the connectors 41 are positioned opposite each other on the transmission belts 211 of the two sets of transmission pairs 21. The door panels 42 are positioned on the connectors 41 in a direction perpendicular to the movement of the transmission belt 211, and both ends are connected to the connectors 41 on the transmission belts 211 of the corresponding sets of transmission pairs 21. The multiple door panels 42 correspond to the multiple connectors 41. The multiple door panels 42 can move sequentially from the side plate 202 to the door panel 201 as the transmission belt 211 moves, gradually closing the opening 203.

[0058] In some embodiments, the transmission belt 211 is a transmission chain, and the connector 41 is disposed on the transmission chain plate of the transmission chain. The connector 41 and the transmission chain plate can be fixedly connected by screws or by welding, and the connector 41 can also be integrally formed with the transmission chain plate.

[0059] The number of connectors 41 and door panels 42 is determined according to the width of the opening 203, so as to ensure that all door panels 42 can be arranged in sequence to completely cover the opening 203 when the door is closed.

[0060] In some embodiments, the flexible door assembly 40 further includes a sealing cloth. The sealing cloth is attached to the plurality of door panels 42 or the connector 41. The sealing cloth can further seal the opening 203 when the door panel 42 closes the opening 203 to prevent dust, moisture, etc. from entering.

[0061] Please also refer to Figure 4 and Figure 5 When the door is opened, the drive wheel 12 is driven to rotate by the drive component 11, which causes the drive belt 15 to drive the driven wheel 13 to rotate, thereby driving the drive shaft 14 to rotate. The transmission wheel 212 on the drive shaft 14 rotates accordingly, thereby driving the transmission belt 211 to move. The moving transmission belt 211 drives the multiple door panels 42 connected to it by the connector 41 to move away from the opening 203. After passing the steering wheel 32, the door panels 42 are moved to the side panel 202 for storage.

[0062] The door opening structure 100 is driven by the drive component 10, which drives the transmission belt 211 to move. The direction of movement of the transmission belt 211 is changed by the steering component 30. Finally, the flexible door assembly 40 composed of door panels 42 moves to achieve flexible opening and closing of the door, thereby effectively solving the problem of needing a horizontal swing door in a space-constrained environment.

[0063] Example 2

[0064] Please see Figures 1 to 5 The second embodiment of this application also provides an automated device. The automated device includes a door frame 200 and a door opening structure 100 as described in Embodiment 1. The door opening structure 100 is mounted on the door frame 200.

[0065] The door opening structure 100, through the cooperation of the drive component 10, transmission component 20, steering component 30 and flexible door component 40, can change the spatial position of the door when it is opened, thereby avoiding the problem of excessive space required by traditional rigid doors and effectively solving the problem of needing a horizontal swing door in a space-constrained situation.
