Description

Technical Field

[0001] The present invention relates to sliding door mechanism technology, in particular to a sliding door based on an intermittent motion mechanism. Background Art

[0002] Sliding door is a general term for electric, pneumatic or manual sliding door mechanism. The closed state of this sliding door can be set as the zero point of the door body's own motion coordinate. When the door body slides under force and leaves the coordinate zero point, it gives up the space originally filled by the door body at the zero point. This given up space is the opening space of the door body.

[0003] Existing sliding doors use a variety of technical routes to achieve the movement of the door body. Some change the power source, some change the transmission mechanism, some change the support and stability structure, some change the door body running structure, and some change the electrical control method. These technical routes have their own characteristics, and their unique features can adapt to certain special working conditions.

[0004] A new requirement for sliding doors in current engineering applications requires that they be compatible with manual, pneumatic, and electric power sources, that the transmission system be able to convert the constant speed input of the power source into intermittent variable speed motion of the door body, and that the power source be located externally and not move with the door body. Existing publicly available sliding doors do not adequately meet these specialized operating conditions, and a new sliding door is needed to meet these practical engineering application requirements. Summary of the Invention

[0012] Furthermore, the main door is provided with a receiving space, and the auxiliary door can be stored in the receiving space of the main door.

[0013] Furthermore, the linkage component includes a linkage synchronous belt and a linkage driven wheel, the linkage synchronous belt is wound around the linkage driven wheel and the linkage driving wheel, and the linkage synchronous belt is provided with a secondary door connecting piece, and the linkage synchronous belt is connected to the secondary door through the secondary door connecting piece.

[0015] Furthermore, the power source is a motor or a gas tank.

[0016] Furthermore, the power transmission mechanism is a synchronous belt, a chain, a screw rod or a guide rail slider.

[0043] Example

[0044] See also Figures 1 to 6 A sliding door based on an intermittent motion mechanism includes a main door 1, a secondary door 2, a drive assembly 5, a linkage assembly 7, and an intermittent motion mechanism 6. The main door 1 is a door body that can be pushed and slid on the ground, preferably a frame structure. The secondary door 2 is a door body set on the main door and can be pushed and slid. Specifically, the main door 1 is provided with a slide seat 11, and the top of the slide seat 11 is provided with a slide slot 12. The secondary door 2 is correspondingly provided with a slide rail 21. The secondary door 2 moves along the slide slot 12 of the main door 1 along the width direction of the main door through the slide rail 21. The slide seat 11 can be set at the front or rear side of the main door 1 as needed, or the slide seat can be set on both the front and rear sides of the main door 1. In this way, the side storage secondary door 2B can be parallel to the front or rear side or both the front and rear sides of the main door when stored. Preferably, the main door 1 is provided with a accommodating space, the slide seat 11 is arranged in the accommodating space of the main door 1, and the internal storage sub-door 2A can be stored in the accommodating space inside the main door 1, so that the overall structure of the sliding door is more simple and compact when stored.

[0045] The driving assembly 5 is connected to the main door 1, and the driving assembly 5 is used to drive the main door 1 to reciprocate along the width direction of the main door; the driving assembly 5 includes a power source and a power transmission mechanism, the power source is used to provide driving force to the main door 1 through the power transmission mechanism, so that the main door 1 reciprocates along the width direction of the main door, the power source is preferably a motor 51, and the power transmission mechanism is preferably a synchronous belt 53. A synchronous belt driving wheel is provided on the rotating shaft of the motor 51, and a synchronous belt driven wheel 52 is provided at the end of the main door moving direction away from the motor. The synchronous belt 53 is wound around the synchronous belt driving wheel and the synchronous belt driven wheel 52, and the length direction of the synchronous belt is consistent with the width direction of the main door. The synchronous belt 53 is provided with a main door connecting member 54 connected to the main door. The rotation of the rotating shaft of the motor 1 drives the synchronous belt driving wheel to rotate, and then drives the synchronous belt 53 to rotate around the synchronous belt driving wheel and the synchronous belt driven wheel 52. The main door connecting member 54 can reciprocate along the length direction of the synchronous belt 53, thereby driving the main door 1 to reciprocate along the length direction of the synchronous belt.

[0046] Similarly, the power source can also be a gas-driven system, which includes an air compressor that inflates the gas tank, a gas tank for storing compressed gas, and a cylinder for actuating the main door. The compressed gas drives the cylinder to move, thereby actuating the main door. In the event of an unexpected situation and the power source fails, the main door can be manually actuated.

[0047] The power transmission mechanism can also be a toothed disc with a chain, a screw rod or a guide rail with a slider, etc.

[0048] The main door 1 is connected to the linkage assembly 7 through an intermittent motion mechanism 6. The intermittent motion mechanism 6 includes a gear 61, a guide rail 62, a wheel axle 63 and a linkage drive wheel 71. The gear 61 is fixed to the main door 1 through a gear mounting seat 13. The lower end of the wheel axle 63 is connected to the gear 61, and the upper end of the wheel axle 63 is connected to the linkage drive wheel 71. The gear 61 is provided with a boss 611, and the boss 611 is coaxially arranged with the gear 61. The boss 611 is provided with a locking string 612.

[0049] The guide rail 62 is arranged along the width direction of the main door, and the guide rail 62 includes a rack portion 621 and a slide rail portion 622. The slide rail portion 622 is provided with a guide platform 623 corresponding to the locking string 612 of the boss. When the main door 1 is moved, the gear 61 can move along the length direction of the guide rail 62.

[0050] When the power source drives the main door 1 to move along the width direction of the main door, the main door 1 intermittently provides driving force for the linkage assembly 7 through the intermittent motion mechanism 6. Specifically, the gear 61 moves along the guide rail 62 driven by the main door 1. When the gear 61 moves to the T12 period of the rack portion 621 of the guide rail, the gear 61 meshes with the rack, and the gear 61 performs a combined motion of translation and rotation. The rotation of the gear 61 drives the axle 63 to rotate, and then drives the linkage drive wheel 71 to rotate, thereby providing driving force for the linkage assembly 7. When the gear 61 moves to the T11 period of the slide rail portion 622, the guide platform 623 of the slide rail portion cooperates with the locking string 612 of the boss of the gear to prevent the gear 61 from rotating. At this time, the gear 61 performs translational motion along the guide rail 62, the gear 61 stops rotating, and the axle 63 and the linkage drive wheel 71 also stop rotating. At this time, the linkage assembly 7 cannot obtain driving force from the linkage drive wheel 71.

[0051] The linkage component 7 is connected to the auxiliary door 2, and the linkage component 7 is used to drive the auxiliary door 2 to reciprocate along the width direction of the main door. The linkage component 7 includes a linkage synchronous belt 73 and a linkage driven wheel 72. The linkage driven wheel 72 is arranged on the main door 1, and the linkage synchronous belt 73 is connected around the linkage driven wheel 72 and the linkage driving wheel 71. A secondary door connecting member 74 is provided on the linkage synchronous belt 73, and the linkage synchronous belt 73 is connected to the auxiliary door 2 through the secondary door connecting member 74. The linkage synchronous belt 73 rotates around the linkage driven wheel 72 and the linkage driving wheel 71 under the drive of the linkage driving wheel 71, and the secondary door connecting member 74 arranged on the linkage synchronous belt 73 moves along the width direction of the main door with the linkage synchronous belt 73, thereby driving the auxiliary door 2 to move along the width direction of the main door, thereby realizing relative movement between the auxiliary door 2 and the main door 1.

[0052] In order to allow the main door 1 to slide smoothly on the ground, a roller assembly 3 is provided under the main door 1. The roller assembly 3 includes multiple groups of rollers, which can convert the sliding friction between the main door 1 and the ground into rolling friction, making the opening and closing of the main door easier.

[0053] When installing the sliding door, first dig a groove on the ground along the opening and closing direction of the sliding door to accommodate the drive assembly, gears and guide rails of the intermittent motion mechanism and other devices. At the same time, in order to replace the ground to support the main door, it also includes a tread assembly 4, the tread assembly 4 includes a tread 41 and a tread base 42, the tread base 42 is set in the underground groove, the tread 41 is set on the tread base 42, the tread 41 is flush with the ground, and the main door 1 can reciprocate on the tread 41 through the roller assembly 3. At the same time, the tread 41 can also effectively protect the drive assembly and the intermittent motion mechanism and other devices set in the groove.

[0054] In order to facilitate the movement of the wheel axle, the step plate 41 is provided with an avoidance opening corresponding to the wheel axle 63, so that the wheel axle 63 will not be affected by the step plate 41 when it moves horizontally along the width direction of the main door.

[0055] From the above description, it can be seen that the beneficial effects of the present invention are: providing a sliding door based on an intermittent motion mechanism, which can use an external power source, and when the main transmission rate provided by the power source remains unchanged, the sliding door can be accelerated or decelerated within a preset travel segment of the running trajectory. This feature supports a sliding door group composed of multiple sliding doors to obtain an opening width that is much larger than the width of a single door, and has better market prospects.

[0056] Implementation Example

[0057] In one possible implementation, when a sliding door based on an intermittent motion mechanism needs to make a large-scale door opening action, the driving assembly drives the main door to slide on the step plate through the roller assembly. During the sliding process, the intermittent motion mechanism installed on the main door provides a power torque to the linkage assembly as the main door moves, so that the linkage assembly drives the secondary door to slide closer to the main door. At this time, the main door and the secondary door are regarded as a whole retractable sliding door, and the sliding door is performing a sliding and contracting action. Therefore, the expansion of the door opening area is the sliding distance of the main door plus the contraction distance of the secondary door to the main door, thereby obtaining a large-scale door opening action.

[0058] See also Figures 7 and 8 In another possible implementation, if a large-scale door opening action is to be performed by continuously sliding multiple door bodies, the multiple door bodies are in the initial state of T1. At this time, when a large-scale door opening action is required, the driving assembly drives the first main door to slide on the step plate through the roller assembly. During the sliding process, the intermittent motion mechanism installed on the first main door provides a power torque to the linkage assembly as the first main door moves, so that the linkage assembly drives the auxiliary door to slide toward the first main door. At this time, the first main door and its auxiliary door are regarded as a whole retractable first sliding door, and the sliding door is performing a sliding and contracting action. Therefore, the expansion of the door opening area is the sliding distance of the first main door plus the contraction distance of the auxiliary door to the main door, which obtains a large-scale door opening action. After the first sliding door completes the door opening and storage actions, the whole is in the first state of T2.

[0059] Since it is a multi-door opening action, it is necessary to continue moving the above-mentioned first main door on the basis of the above-mentioned door opening action. At this time, the auxiliary door carried by the main door has been fully retracted into position. Therefore, the linkage component cannot be driven in the next stroke of the main door. At this time, the intermittent motion mechanism of the first sliding door needs to be switched from the output torque mode to the non-output torque mode to ensure that the auxiliary door will not continue to be driven by the driving force and cause it to get stuck after it has been fully retracted into position.

[0060] The door opening action continues. While the first sliding door continues to move to the right, the second sliding door's main door begins to retract and simultaneously open. After the second door completes both the opening and retraction actions, the entire door enters the second state, T3. At this point, the intermittent motion mechanism of the second sliding door switches from output torque mode to non-output torque mode, ensuring that the auxiliary door, after fully retracting, will not be subject to further driving force and become stuck.

[0061] The door opening action continues. While the first sliding door and the second sliding door continue to move to the right, the main door of the third sliding door begins to retract and open at the same time. After the third door body completes the door opening and retracting actions, it is in the third state of T4 as a whole and reaches the final door opening state, thereby realizing the increased door opening action of continuous sliding of multiple door bodies.

[0062] It can be seen from this that the sliding door based on the intermittent motion mechanism can accelerate or decelerate the sliding door within a preset travel segment of the running trajectory while keeping the main transmission rate provided by the power source unchanged. This feature supports the sliding door group composed of multiple sliding doors to obtain an opening width that is much larger than the width of a single door.

[0063] The accelerated door-opening effect of the door-opening process is caused by the intermittent motion mechanism driving the secondary door to retract relative to the main door and the main door's own sliding stroke, resulting in an accelerated opening amplitude; the decelerated door-opening effect of the door-opening process is that after the secondary door has completely completed its retraction stroke on the main door, the intermittent motion mechanism switches to not output power to the secondary door. At this time, the door opening amplitude is only the main door's own sliding, which is equivalent to a decrease in the door opening speed.

[0064] Combine Figures 7 and 8 It can be seen that each set of sliding doors completes the contraction action within a fixed length of travel at the initial stage of sliding, and then continues to slide in a contracted state. It is easy to imagine that when these sliding doors are closed and reset, they also first slide back in a contracted state until a fixed length of travel at the end of the stroke, and then begin to extend, and close in place when all sliding doors are fully extended.

[0065] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention's description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
