Description

Technical Field

[0001] This invention relates to a method for controlling a lifting door operating system for opening and closing openings in a control device. The invention also relates to a lifting door operating system for opening and closing openings. Background Technology

[0002] A door operating system for a lifting door typically includes a door connected to a door frame and a drive unit arranged to move the door along the door frame between an open position and a closed position to open and close the opening. The door is commonly used as a garage door or industrial door, and may be a segmented door. The drive unit may also include a motor for moving the door.

[0003] In traditional lift gates, an electric motor mounted above the door uses a cable connected to the door to raise it. These lift gates typically use balance springs to reduce the force required to open, which increases complexity and makes installation cumbersome. If damage occurs to such a traditional lift gate, such as a broken cable, a mechanical device is used to prevent the door from falling.

[0004] To achieve a more efficient door operating system and reduce the complexity and risks associated with its operation, maintenance, and installation, a door operating system with a drive unit mounted on the door has been developed. The door is driven by a drive pinion that engages with a fixed rack extending along a predetermined movement trajectory of the door. This door system, by introducing a drive module, addresses some of the shortcomings and drawbacks of traditional door operating systems, making installation simpler, faster, and less complex. Furthermore, it eliminates the need for a balancing spring.

[0005] The fixed rack requires high precision in manufacturing, and it must be properly aligned during door installation. This increases the cost of the door itself and its installation.

[0006] To achieve high precision and proper rack alignment, a chain drive can be used. In this system, the drive sprocket on the door can engage with a chain extending to the side of the door.

[0007] However, this requires a lifting door operating system that helps avoid widespread damage related to door operation. Summary of the Invention

[0008] The purpose of this application is to mitigate or eliminate one or more of the aforementioned defects and disadvantages in the art, either individually or in any combination.

[0009] One of the objectives of this application is to provide a method in a control device for controlling a lifting door operating system for opening and closing an opening, which helps to mitigate or eliminate widespread damage associated with the lifting door operating system.

[0010] One of the purposes of this application is to provide a lifting door operating system that helps to mitigate or eliminate widespread damage associated with lifting door operating systems.

[0011] According to a first aspect, a method for controlling a lifting door operating system is provided in a control device. The lifting door operating system is configured to open and close an opening. The lifting door operating system includes a door frame including a first frame section located on a first side of the opening and a second frame section located on a second side of the opening opposite the first side. The lifting door operating system also includes a door arranged to move between an open position and a closed position, the door being movably connected to the door frame. The lifting door operating system further includes a drive unit mounted on the door, the drive unit including at least one motor arranged to move the door from a closed position to an open position; and a first elongated transmission member extending along the first side of the opening and the first frame section. The drive unit also includes a first driven transmission member connected to the motor, the first driven transmission member being movably connected to the first elongated transmission member and arranged to cooperate with the first elongated transmission member to drive the first driven transmission member along the first elongated transmission member, thereby moving the door between the closed and open positions. The method includes the following steps: receiving one or more signals from detections related to door movement; determining, based on the received signals, whether the detected door movement is related to accidental door movement; and if it is determined that the detected door movement is related to accidental door movement, taking action to prevent further damage. By utilizing information from the detection of door movement, accidental door movement can be determined simply and effectively, and widespread damage related to lifting door operating systems can be mitigated or eliminated in a simple and effective manner.

[0012] According to one aspect of this method, the steps of taking action include activating a braking function to prevent uncontrolled door movement. By activating the braking function based on determined, unexpected door movement, more widespread damage related to the lifting door operating system can be effectively prevented.

[0013] According to one aspect of the method, the drive unit includes at least one brake, wherein the step of activating the braking function to prevent uncontrolled door movement includes providing braking force by means of at least one brake abutting against a first side and / or a second side to prevent door movement. By providing braking force by means of at least one brake abutting against a first side and / or a second side based on a determined accidental door movement, more extensive damage related to the lifting door operating system can be effectively prevented.

[0014] According to one aspect of this method, the steps of taking action include preventing the operation of the door operating system related to opening and closing the opening. By preventing the operation of the door operating system related to opening and closing the opening based on determined accidental door movement, more widespread damage related to the lifting door operating system can be effectively prevented. If, for example, there is an impact acting on the door caused by a vehicle, this can, for example, prevent the activation of the door operating system.

[0015] According to one aspect of this method, the step of receiving one or more signals from the detection of door movement includes receiving acceleration signals and / or vibration signals from the detection of door movement. By utilizing acceleration detection information from the acceleration detection of door movement, unexpected door movement can be accurately determined in a simple and effective manner.

[0016] According to one aspect of this method, the step of receiving one or more signals from detections related to door movement includes receiving a torque signal from torque detection of at least one motor of the door. By utilizing the detection information from torque detection of at least one motor of the door, unexpected door movement can be effectively determined.

[0017] According to one aspect of the method, the drive unit further includes a second elongated transmission member extending along a second side of the opening and a second frame segment. The drive unit also includes a second driven transmission member arranged to cooperate with the second elongated transmission member. The drive unit includes a motor drivenly connected to the second driven transmission member. The step of receiving one or more signals from detections related to door movement includes receiving one or more signals from detections related to movement of a door connected to a first side and one or more signals from detections related to movement of a door connected to a second side. The method of determining whether the detected door movement is related to accidental door movement includes the steps of comparing the signals related to movement of the door connected to the first side and the signals related to movement of the door connected to the second side, and determining that the detected door movement is related to accidental door movement if the difference between the movement of the door connected to the first side and the movement of the door connected to the second side exceeds a certain threshold. Therefore, damage, such as a broken elongated transmission member located on one side, can be effectively and accurately identified, further facilitating the prevention of more widespread damage through action.

[0018] According to one aspect of this method, the drive unit includes a first motor drivenly connected to a first driven transmission member; and a second motor drivenly connected to a second driven transmission member. The step of activating the braking function to prevent uncontrolled movement of the door includes braking via the motor drivenly connected to the driven transmission member, wherein the elongated transmission member and the driven transmission member still function. Therefore, braking can be achieved simply and effectively using a braking member associated with the motor driven by the driven transmission member, wherein the elongated transmission member and the driven transmission member are still operational. Thus, the first braking member can be positioned connected to the first motor, for example, arranged on the motor shaft of the first motor, and the second braking member can be positioned connected to the second motor, for example, arranged on the motor shaft of the second motor. Such a braking member can be activated to provide braking force, for example, against the elongated transmission member and / or the driven transmission member, when no energy is supplied to the motor.

[0019] According to one aspect of the method, the step of receiving one or more signals from detections related to door movement includes: receiving one or more signals from detections related to door opening and closing movements during normal operation; and storing information from the detections related to door opening and closing movements during normal operation. The step of determining whether the detected door movement is related to unexpected door movement includes: comparing the signals related to door movement with the stored information from the detections related to door opening and closing movements during normal operation; and determining that the detected door movement is related to unexpected door movement if the difference between the detected door movement and the stored information on door movement during normal operation exceeds a certain threshold. Normal operation here refers to the operation of a lifting door operating system involving the trouble-free opening and closing of the door, i.e., raising and lowering. The method may include the step of determining whether the detections related to door opening and closing movements indicate normal, trouble-free opening and closing. This can be obtained by determining the average value of a certain number of cycle returns, which will detect sudden changes rather than gradual wear. Therefore, by comparing the stored information on door opening and closing movements during normal operation with door movement information, unexpected door movement can be accurately determined in a simple and effective manner. According to one aspect of this application, stored information on unexpected door movements is compared with actual door movements. If the detected door movement substantially corresponds to the stored unexpected door movement, then it is determined that the door movement is related to the unexpected door movement. Thus, unexpected door movements can be accurately determined in a simple and effective manner.

[0020] According to one aspect of the method, the step of determining whether the detected door movement is related to the unexpected door movement includes: comparing a signal related to the door movement with stored information about the unexpected door movement; and determining that the detected door movement is related to the unexpected door movement if the detected door movement substantially corresponds to the stored information about the unexpected door movement.

[0021] According to one aspect of the method, the stored information about unexpected door movement includes information about different types of unexpected door movement and information about possible causes of each type, wherein if the detected door movement substantially corresponds to the stored information about unexpected door movement, the step of determining that the detected door movement is related to the unexpected door movement includes determining the type of the determined unexpected door movement and thereby determining the possible causes of the unexpected door movement.

[0022] According to one aspect of this disclosure, the method may include the step of filtering received erroneous signals. Such erroneous signals may be related to noise in the electronic device or to minor movements of the door unrelated to unexpected door movement requiring action.

[0023] According to a second aspect, a lifting door operating system for opening and closing an opening is provided. The lifting door operating system includes a control device that controls the lifting door operating system. The lifting door operating system includes a door frame comprising a first frame segment and a second frame segment, the first frame segment located on a first side of the opening, and the second frame segment located on a second side of the opening opposite the first side. The lifting door operating system also includes a door arranged to move between an open position and a closed position, the door being movably connected to the door frame. The lifting door operating system further includes: a drive unit mounted on the door. The drive unit includes at least one motor arranged to move the door from a closed position to an open position; and a first elongated transmission member extending along the first side of the opening and the first frame segment. The drive unit also includes a first driven transmission member drivenly connected to the motor, the first driven transmission member being movably connected to the first elongated transmission member and arranged to cooperate with the first elongated transmission member to drive the first driven transmission member along the first elongated transmission member, thereby moving the door between the closed position and the open position. The control device is configured to: receive one or more signals from a detection related to the movement of the door; determine, based on the received signals, whether the detected door movement is related to an accidental door movement; and, if it is determined that the detected door movement is related to an accidental door movement, take action to prevent further damage.

[0024] According to one aspect of the lifting door operating system, the control device is configured to activate a braking function to prevent uncontrolled door movement.

[0025] According to one aspect of the lifting door operating system, the drive unit includes at least one brake, wherein the control device is configured to activate at least one brake when the door's movement braking function is activated to prevent uncontrolled door movement, so as to provide braking force by at least one last brake abutting against a first side and / or a second side, thereby preventing door movement.

[0026] According to one aspect of the lifting door operating system, the control device is configured to prevent the operation of the door operating system related to opening and closing openings when taking action.

[0027] According to one aspect of a lifting door operating system, the control device is configured to receive, upon receiving one or more signals related to the detection of door movement, acceleration signals and / or vibration signals from one or more motion sensors connected to the door. The one or more motion sensors may include one or more acceleration sensors, such as accelerometers, and / or one or more vibration sensors, such as mercury sensors. The one or more acceleration sensors and / or one or more vibration sensors are connected to the door.

[0028] According to one aspect of the lifting door operating system, the control device is configured to receive a torque detection signal from at least one motor of the door via a torque sensor connected to at least one motor when receiving one or more signals from a detection related to the movement of the door.

[0029] According to one aspect of the lifting door operating system, the drive unit further includes a second elongated transmission member extending along a second side of the opening and a second frame segment. The drive unit also includes a second driven transmission member arranged to cooperate with the second elongated transmission member. The drive unit includes a motor drivenly connected to the second driven transmission member. The control device is configured to receive, upon receiving one or more signals related to the movement of the door, one or more signals related to the movement of the door connected to the first side, and one or more signals related to the movement of the door connected to the second side. The control device is configured to, when determining whether the detected door movement is related to an unexpected door movement, compare the signals related to the movement of the door connected to the first side and the signals related to the movement of the door connected to the second side, and if the difference between the movement of the door connected to the first side and the movement of the door connected to the second side exceeds a certain threshold, determine that the detected door movement is related to an unexpected door movement.

[0030] According to one aspect of the lifting door operating system, the drive unit includes: a first motor drivenly connected to a first driven transmission member; and a second motor drivenly connected to a second driven transmission member. The control device is configured to activate the braking function of the motor driven by the driven transmission member when a braking function is activated to prevent uncontrolled door movement, wherein the elongated transmission member and the driven transmission member still function.

[0031] According to one aspect of a lifting door operating system, the control device is configured to receive, upon receiving one or more signals from detections related to door movement, one or more signals from detections related to door opening and closing movements during normal operation; and to store information from the detections related to door opening and closing movements during normal operation. The control device is configured to, when determining whether a detected door movement is related to an unexpected door movement, compare the signals related to door movement with the stored information from the detections related to door opening and closing movements during normal operation; and if the difference between the detected door movement and the stored information related to door movement during normal operation exceeds a certain threshold, determine that the detected door movement is related to an unexpected door movement. In this document, normal operation refers to the operation of the lifting door operating system involving the trouble-free opening and closing of the door, i.e., raising and lowering. This can be configured to determine whether the detections related to door opening and closing movements indicate normal and trouble-free opening and closing. This can be obtained by determining the average value of a certain number of cycle returns, which will detect sudden changes rather than gradual wear.

[0032] According to one aspect of the lifting door operating system, the control device is configured to compare a signal related to the door movement with stored information about the unexpected door movement when determining whether the detected door movement is related to the unexpected door movement; and if the detected door movement substantially corresponds to the stored information about the unexpected door movement, then it is determined that the detected door movement is related to the unexpected door movement.

[0033] According to one aspect of the lifting door operating system, the stored information about unexpected door movement includes information about different types of unexpected door movement and possible causes of each type, wherein the control device (100) is configured to determine the type of unexpected door movement and the possible causes of the unexpected door movement when it is determined that the detected door movement is related to the unexpected door movement if the detected door movement substantially corresponds to the stored information about unexpected door movement.

[0034] According to one aspect of this application, the control device of the lifting door operating system can be configured to filter received error signals. Such error signals may be related to noise from the electronic devices or to minor door movements unrelated to unexpected door movements requiring action.

[0051] Embodiments of the invention will now be described with reference to the accompanying drawings. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the application thorough and complete and to fully convey the scope of the invention to those skilled in the art. The terminology used in the detailed description of the specific embodiments shown in the drawings is not intended to limit the invention. In the drawings, the same reference numerals denote the same elements.

[0052] Figure 1 This is a schematic diagram of a door operating system 1. The invention can be applied to the door operating system 1. The door operating system includes a door frame 3 and a drive unit 10 (such as...). Figures 2a to 2c(As shown) and door 8. Door operating system 1 is arranged to be installed in opening 2 defined by walls and floor. Door 8 is connected to door frame 3. Door operating system 1 is arranged to open and close opening 2 by moving door 8 between open position O and closed position C. Open position O can be a horizontal open position O in the form of a planar horizontal position or an inclined horizontal position. Closed position C can be a vertical closed position C.

[0053] In this embodiment, door 8 is a segmented door 8, comprising a plurality of horizontally connected and interconnected segments 9a to 9e connected to door frame 3. In one embodiment, the door is a garage door. In another embodiment, the door is an industrial door. Door 8 is arranged to move along door frame 3 between a closed position C and an open position O.

[0054] like Figure 1 As shown, the gate operating system 1 may include a first terminal 13 and a second terminal 14. At least one of the first terminal 13 and the second terminal 14 is configured to transmit energy to charge an energy storage device (such as a battery) for powering a motor of a drive unit. In another embodiment, the motor of the drive unit may be powered via a wire.

[0055] The door operating system is an upward-opening door operating system. An upward-opening door operating system is a system in which the door in the closed position C is arranged substantially vertically, and the door in the open position O is arranged substantially horizontally within the opening.

[0056] In another embodiment, the door operating system is one in which the door in the closed position C is arranged substantially vertically, and the door in the open position O is arranged at an angle between substantially vertical and substantially horizontal. For example, in the open position O, the door can be arranged at an angle of 45° to the horizontal position, and as those skilled in the art will recognize, in the open position O, the door can be arranged at any angle between the horizontal and vertical directions of the door.

[0057] The door frame 3 includes a first frame section 4 located on a first side 7 of the opening 2 and a second frame section 6 located on a second side 5 of the opening 2. The door frame 3 is connected to the wall and the floor, i.e., the floor of the opening 2. In one embodiment, the first frame section 4 includes a generally vertical extension 4a and a generally horizontal extension 4b. The second frame section 6 includes a generally vertical extension 6a and a generally horizontal extension 6b. The vertical extensions 4a and 6a and the horizontal extensions 4b and 6b are connected to form a path for the door 8 to slide and a track that cooperates with the drive unit 10.

[0058] Therefore, each of the first frame segment 4 and the second frame segment 6 includes vertical extensions 4a and 6a; horizontal extensions 4b and 6b; and curved interconnections 4c and 6c. In other words, the first frame segment 4 includes a vertical extension 4a, a horizontal extension 4b, and a curved interconnection 4c. The curved interconnection 4c connects the vertical extension 4a and the horizontal extension 4b. Similarly, the second frame segment 6 includes a vertical extension 6a, a horizontal extension 6b, and a curved interconnection 6c. The curved interconnection 6c connects the vertical extension 6a and the horizontal extension 6b.

[0059] The vertical extensions 4a and 6a can be vertical portions 4a and 6a or inclined vertical portions 4a and 6a. Similarly, the horizontal extensions 4b and 6b can be horizontal portions 4b and 6b or inclined horizontal portions 4b and 6b.

[0060] Reference Figure 1 Door 8 is directly or indirectly connected to door frame 3. Door 8 is movably connected to first frame section 4 on a first side and movably connected to second frame section 6 on a second side. In one embodiment, one or more of a plurality of sections 9a to 9e are connected to first frame section 4 on the first side 7 and to second frame section 6 on the second side 5.

[0061] Reference Figures 2a to 2c The drive unit 10 is mounted on the door 8. The drive unit 10 includes at least one motor 11. The at least one motor 11 is arranged to move the door 8 from the closed position C to the open position O.

[0062] To allow the drive door 8 to be driven, the lifting door operating system 1 also includes an elongated drive member 19 extending along a first side 7 of the opening 2. The elongated drive member 19 may further extend along the first frame segment 4. The drive unit 10 also includes a driven drive member 18, which is drivenly connected to the motor 11. The driven drive member 18 is movably connected to the elongated drive member 19 and arranged to cooperate with the elongated drive member 19 to drive the driven drive member 18 along the elongated drive member 19 by the elongated drive member 19 at least partially surrounding the driven drive member 18. Thus, the elongated drive member 19 is arranged to at least partially enclose the driven drive member 18.

[0063] Compared to fixed brackets, elongated transmission components offer a more cost-effective solution in terms of both manufacturing and installation. Furthermore, elongated transmission components allow relative movement between door 8 and the door frame without requiring the high precision and proper alignment required by fixed bracket solutions. Elongated transmission components can therefore be arranged to allow a degree of movement along a direction orthogonal to the first frame segment 4.

[0064] Furthermore, since the elongated transmission element follows and maintains engagement with the driven transmission element at least to some extent, even if the door is pushed off the track, the elongated transmission element makes the door operating system safer. In addition, compared to a fixed frame, the elongated transmission element is quieter, more wear-resistant, and less likely to fail due to pressure from external objects.

[0065] The elongated transmission member 19 can be a flexible transmission member. The elongated transmission member 19 can be a suspended transmission member. It should be noted that "flexible" in this context does not necessarily mean that the transmission member must be flexible, but only that it can surround the driven transmission member. Accordingly, the transmission member 19 can be considered as being arranged to engage with the driven transmission member 18 and provide relative movement between the driven transmission member 18 and the direction of movement of the door 8 as defined by the door frame 3. In other words, the transmission member can be considered as a non-fixed transmission member or a suspended transmission member. The elongated transmission member can be correspondingly arranged to engage with a driven transmission member independent of the door frame.

[0066] A drive unit 10 is movably connected to an elongated transmission member 19. Accordingly, the drive unit 10 is connected to the elongated transmission member 19 to allow relative movement between the door and the door frame, thereby fixing the drive unit to the door. The drive unit 10 includes at least one motor 11. The drive unit 10 is arranged to move the door 8 from a closed position to an open position. To provide power to the motor 11, the at least one motor 11 may be connected to at least one energy storage device (e.g., a battery), which is arranged to power the at least one motor 11. The drive unit 10 is arranged to move the door 8 from a closed position C to an open position O.

[0067] In one embodiment, the drive unit 10 is arranged to move the door from the open position O to the closed position C. In one embodiment, the door 8 is arranged to move from the open position O to the closed position C by its own weight. In one embodiment, the drive unit 10 is arranged to brake the door 8 when it moves from the open position O to the closed position C.

[0068] In one embodiment, the elongated transmission element can be suspended only by its top and bottom ends.

[0069] The elongated transmission element 19 can be biased. The biasing of the elongated transmission element 19 can maintain the tension of the elastic elongated component 19 at a suitable level and further compensate for wear and potential tolerance issues.

[0070] In one embodiment, the elongated transmission member 19 can be biased by an arrangement of springs. The top end of the elongated transmission member 19 can be fixedly mounted, and the bottom end of the elongated transmission member 19 can be spring-loaded. This allows for easier access by personnel performing maintenance work involving the springs. In one embodiment, the top and bottom ends of the elongated transmission member 19 are mounted to a door frame, such as the first frame segment 4.

[0071] In one embodiment, the lifting door operating system further includes at least one guide member 92. The at least one guide member 92 is mounted to the door 8. The guide member 92 may be arranged to cooperate with an elongated drive member 19 to guide the door 8 along the elongated drive member 19, which at least partially surrounds the at least one guide member 92. The guide member 92 moves the elongated drive member 19 and guides the driven drive member 18 associated with the elongated drive member 19 to proper alignment. Thus, a more reliable door operating system is achieved. Preferably, the guide member 92 is a rotatable guide member that can be mounted to the door 8 via a journal connection. Therefore, the elongated drive member 19 may be arranged to at least partially enclose the guide member 92.

[0072] Reference Figures 2a to 2c The elongated transmission member 19 can be arranged to surround a portion of the driven transmission member 18 and a portion of the guide member 92, and mate with a portion of the driven transmission member 18 and a portion of the guide member 92. The portion of the driven transmission member 18 that mates with the elongated transmission member 19 is opposite to the portion of the guide member 92 that mates with the elongated transmission member 19. This achieves greater contact between the driven transmission member, the guide member, and the elongated transmission member, thereby enabling a more stable lifting door operating system that requires less torque to operate.

[0073] like Figure 2c As shown, the slender transmission member 19 is suspended there along the first side 7 of the opening.

[0074] The elongated drive element 19 can be any conventional elongated drive element 19, providing the necessary slack to compensate for the horizontal or diagonal movement of the drive unit and / or the door. The elongated drive element can be a belt or a chain.

[0075] In one embodiment, the elongated transmission member 19 may be a belt. Therefore, the guide member 92 and the driven transmission member 18 may be pulley elements arranged to engage with the belt. In one embodiment, the belt may be a V-belt or a multi-ribbed belt, whereby the guide member 92 and the driven transmission member 18 may be gears engaging with the ribs of the V-belt or multi-ribbed belt.

[0076] The slender transmission component 19 can also be in Figures 2a to 2cThe chain shown is an example. The chain may be provided with slots for receiving gears. Accordingly, the driven member 18 may be a gear arranged to engage with the chain (e.g., a slot in the chain). The driven member 18 may be a sprocket. Furthermore, the guide member 92 may be a gear arranged to engage with the chain (e.g., a slot in the chain). The guide member 92 may be a sprocket. In one embodiment, the guide member 92 may be a ribbed wheel that engages with the chain. In one embodiment, the chain is an endless loop chain that encloses one or more guide members and one or more driven members. In one embodiment, the chain is a non-endless loop chain, for example, a single chain that only partially encloses one or more guide members and one or more driven members.

[0077] In one embodiment, the lifting door operating system further includes a first guide roller assembly 17 and a second guide roller assembly 17. The first and second guide roller assemblies are mounted to the door 8. The first guide roller assembly 17 is arranged to cooperate with a first frame segment 4, and the second guide roller assembly 17 is arranged to cooperate with a second frame segment 6. Therefore, the guide rollers and the door 8 move together in a guided manner along a track formed by the door frame (e.g., the first frame segment 4 and the second frame segment 6).

[0078] In one embodiment, door 8 is a segmented door. Therefore, the door comprises multiple horizontal and interconnected segments 9a to 9e (e.g., Figure 1 (As shown).

[0079] Refer again Figures 2a to 2c The drive unit 10 is installed on section 9e of the door 8. To make the movement of this section smoother, the section on which the drive unit 10 is installed is provided with two pairs of guide rollers. The first upper guide roller and the second upper guide roller extend from section 9e to the first frame section 4 and the second frame section 6, respectively. Similarly, the first lower guide roller and the second lower guide roller also extend from section 9e to the first frame section and the second frame section 6, respectively.

[0080] In one embodiment, the drive unit 10 is mounted to the bottommost section 9e of the door 8. According to this embodiment, the first and second lower guide rollers can be arranged near the lower horizontal end of the bottommost section 9e. Correspondingly, the upper guide roller can be arranged near the upper horizontal end of the bottommost section 9e.

[0081] In one embodiment, the upper guide roller and the lower guide roller may be installed in one of the sections 9a to 9e. Preferably, the upper guide roller is arranged near the upper horizontal end of each section, and the lower guide roller is arranged adjacent to the lower horizontal end of each section.

[0082] At least one guide member 92 may be arranged coaxially with one of the guide rollers 17. Since the frame and guide rollers bear part of the load during door movement, the coaxial arrangement reduces the force on the guide member. Therefore, the resultant force on the door section and on the bearings of the drive unit and / or guide member is reduced. Furthermore, the coaxial configuration allows more elongated drive components to be positioned behind the guide roller, which reduces the exposure of said elongated drive components. The guide roller 17 is mounted to the door 8 via a shaft 88. Both the guide roller 17 and the guide member 92 are mounted to the shaft. The guide member 92 may be fixedly connected to the shaft 88. Advantageously, the guide roller 17 and the guide member 92 may be arranged near the lower horizontal edge of the door 8. In one embodiment, the guide member is integrated into the guide roller.

[0083] Coaxiality here means that the guide rollers and guide elements are arranged parallel to each other along a horizontally extending axis. The horizontal axis extends between the first frame section and the second frame section.

[0084] In one embodiment, the guide member is coaxial with the guide roller, which is positioned near the lower horizontal end of the bottommost section 9e of the door. This is particularly advantageous because it provides a greater pivoting position for the door. Thus, when the lifting door operating system is an upward-opening operating system, the guide roller and guide member create a common low pivot point for the door as it approaches its open position O. This significantly reduces the space required above the door opening compared to, for example, doors with a drive section using a fixed frame.

[0085] In one embodiment, the first upper guide 92 is arranged coaxially with the first upper guide roller 17. Correspondingly, the first lower guide 92 is arranged coaxially with the first lower guide roller 17. Therefore, the driven segment 9e can be guided along the elongated transmission member 17 and the door frame on the same axis. This further improves stability and reduces the load on the segment on which the drive unit 10 is mounted. Preferably, this segment is the bottommost segment, and the lower guide and lower guide wheel are arranged near the lower end of said bottommost segment. Therefore, one of the guide wheels 17 and one of the guides 92 can be arranged coaxially with each other and near the lower horizontal edge of the door 8. This can also be done in a single-segment door.

[0086] In one embodiment, see, for example Figure 3b The lifting door operating system includes a pair of elongated drive members to stabilize the movement of the door 8. A first elongated drive member 19 extends along the first side 7 of the opening 2. The first elongated drive member 19 may also extend along the first frame section 4. A second elongated drive member 19 extends along the second side 5 of the opening 2. The second elongated drive member 19 may also extend along the second frame section 6. The guiding and driving arrangement discussed with reference to the first side of the door can be correspondingly reflected on the second side of the door.

[0087] Therefore, the lifting door operating system may also include a first driven transmission member 18 and a second driven transmission member 18, the first driven transmission member 18 and the second driven transmission member 18 being arranged to cooperate with the first and second elongated transmission members 19 respectively by a first elongated transmission member and the second elongated transmission member that at least partially surround the first driven transmission member and the second driven transmission member.

[0088] The first driven transmission member 18 and the second driven transmission member 18 can be driven by one or more motors 11. In one embodiment, a single motor 11 is drivenly connected to the first and second transmission members 18. The single motor 11 can be connected to the first and second driven transmission members 18 via a first shaft and a second shaft extending from the motor 11. As will be further described with reference to FIG3, the drive unit 10 may include a first motor and a second motor, each of the first motor and the second motor being drivenly connected to the first driven transmission member 18 and the second driven transmission member 18, respectively.

[0089] Similar to the first vertical side of a door, the second side of the door may have one or more guides mounted on the second side. In one embodiment, the lifting door operating system further includes at least one guide 92 mounted to the door 8, the at least one guide 92 being arranged to cooperate with a second elongated drive member to guide the door 8 along a second elongated drive member 17 by means of a second elongated drive member at least partially surrounding the guide. In other words, the door operating system includes: at least one first guide 92 mounted to the door 8, the first guide 92 being arranged to cooperate with a first elongated drive member 19 by means of a first elongated drive member at least partially surrounding the first guide; and at least one second guide 92 mounted to the door 8, the second guide 92 being arranged to cooperate with a second elongated drive member 19 by means of a second elongated drive member at least partially surrounding the second guide.

[0090] Both elongated transmission elements 19 can be biased by a spring arrangement. The top end of the elongated transmission element 19 can be fixedly mounted, and the bottom end of the elongated transmission element 19 can be spring-loaded. This makes it easier for operators performing maintenance work involving the springs to access the device. In one embodiment, the top and bottom ends of the elongated transmission element 19 are mounted to a frame, for example, to a first frame section and a second frame section, respectively.

[0091] In one embodiment, as in Figure 2bAs exemplarily illustrated, a first driven transmission member 18 may be arranged between a first upper guide member 92 and a first lower guide member 92. The first upper guide member 92 and the first lower guide member 92 are arranged to engage with a first elongated transmission member 19 via a first elongated transmission member that at least partially surrounds the first upper guide member and the first lower guide member. Similarly, a second driven transmission member 18 may be arranged between a second upper guide member 92 and a second lower guide member 92. The second upper guide member 92 and the second lower guide member 92 are arranged to engage with a second elongated transmission member via a second elongated transmission member that at least partially surrounds the second upper guide member and the second lower guide member. This allows for additional guidance of the elongated transmission member in the drive direction, both before and after the driven transmission member, without requiring additional components. Thus, a low-complexity operating assembly is achieved. Furthermore, this achieves greater contact between the elongated transmission member and the guide member above the driven transmission member, resulting in a more stable door operating system that requires less torque to operate.

[0092] The first driven transmission member 18 and the second driven transmission member 18 can be arranged to extend from the door 8 in opposite directions toward the first elongated transmission member 19 and the second elongated transmission member 19, respectively. The first driven transmission member 18 can be arranged near the first vertical phase of the door, where the first phase is located near the first elongated transmission member when the door is in the closed position. Similarly, the second driven transmission member 18 can be arranged near the second vertical phase of the door, where the second phase is located near the second elongated transmission member when the door is in the closed position.

[0093] The elongated transmission member 19 can be arranged to surround a portion of the driven transmission member 18 and a portion of the upper and lower guide members 92, and mates with the portion surrounding the driven transmission member 18 and the portion of the upper and lower guide members 92. The portion of the driven transmission member 18 that mates with the elongated transmission member 19 is opposite to the portion of the upper and lower guide members 92 that mates with the elongated transmission member 19. This achieves greater contact between the driven transmission member, the guide members, and the elongated transmission member, thereby enabling a more stable lifting door operating system that requires less torque to operate.

[0094] In one embodiment, only the first elongated transmission member is driven connected to the transmission member, and the door operating system may only include the first upper guide member and the first lower guide member described above.

[0095] In one embodiment, the drive unit 10 is mounted to section 9e of the door 8, and a first upper guide 92, arranged to cooperate with a first elongated transmission member 19, may be arranged near the top of section 9e. A first lower guide 92, arranged to cooperate with the first elongated transmission member 19, may be arranged near the bottom of section 9e. A second upper guide 92, arranged to cooperate with a second elongated transmission member 19, may be arranged near the top of section 9e. A second lower guide 92, arranged to cooperate with the second elongated transmission member 19, may be arranged near the bottom of section 9e.

[0096] In one embodiment, the first upper guide member 92 may be arranged coaxially with the first upper guide roller 17 to engage with the first elongated transmission member 19 via a first elongated transmission member that at least partially surrounds the first upper guide member and the first lower guide member. The first lower guide member 92 may be arranged coaxially with the first lower guide roller 17 to engage with the first elongated transmission member 19. The second upper guide member 92 may be arranged coaxially with the second upper guide roller 17 to engage with the second elongated transmission member 19 via a second elongated transmission member that at least partially surrounds the second upper guide member and the second lower guide member. The second lower guide member 92 may be arranged coaxially with the second lower guide roller 17 to engage with the second elongated transmission member 19.

[0097] like Figures 2a to 2c As shown, the drive unit 10 may include a reduction gear 76 to provide additional torque between the motor and the driven transmission 18. The reduction gear 76 connects the driven transmission 18 and the motor 11. The reduction gear may be in the form of a gearbox 76. The gearbox 76 is capable of selective torque control between, for example, a high-speed mode and a high-torque mode in a door operating system.

[0098] In one embodiment, the drive unit 10 includes a single motor connected to a reduction gear 76, which may be in the form of a gearbox, whereby the output shaft of the gearbox is connected to a first driven transmission 18 and a second driven transmission 18 to transmit torque to the first driven transmission 18 and the second driven transmission 18, or, in the case where the operating system has only one elongated transmission, to transmit torque to a single driven transmission.

[0099] In one embodiment, the drive unit 10 includes a first motor and a second motor. The first motor can be connected to a first reducer, such as a gearbox, and then to a first driven transmission member. The second motor can be connected to a second reducer, such as a gearbox, and then to a second driven transmission member.

[0100] The lifting door operating system may also include at least one transmission element protector 61. The transmission element protector 61 is arranged to at least partially surround a portion of the driven transmission element 18 and the elongated transmission element 19 that engages with the driven transmission element 19. The transmission element protector 61 serves to prevent the elongated transmission element 19 from disengaging from the driven transmission element 18. Therefore, a safer lifting door operating system can be achieved. The transmission element protector 61 also serves to prevent contact between a person and the elongated transmission element 19.

[0101] The transmission element protector 61 can be arranged to extend outward from the door 8, i.e., horizontally, through the elongated transmission element 19 to cover it. The transmission element protector 61 can be connected to the door 8 or the drive unit 10.

[0102] In one embodiment, utilizing a plurality of driven actuators 18, the lifting door operating system may include a plurality of actuator protectors 61. Each actuator protector 61 may be arranged to at least partially surround a portion of the corresponding driven actuator 18 and an elongated actuator 19 that mates with the driven actuator 18.

[0103] In one embodiment, the lifting door operating system may further include a transmission tensioner for a spring-loaded elongated transmission member 19, wherein the top and bottom ends of the elongated transmission member 19 are fixedly mounted and the transmission tensioner is connected to the door 8. The transmission tensioner may include rollers arranged to cooperate with the elongated transmission member 19.

[0104] The operating system of the lifting door may include a spring arrangement. The bottom end of an elongated drive member 19 can be connected to a fixed point via the spring arrangement. The fixed point can be a point on the door frame or the floor. The spring arrangement can be connected to the door frame 3, such as the first frame segment 4, and the bottom end of the elongated drive member 19. The path of the elongated drive member 19 can be downward around a control console element arranged in the floor attachment of the opening, and upward toward the spring arrangement.

[0105] like Figures 2b to 2c As shown, the lifting door operating system may further include a resilient plate 91. The resilient plate 91 is connected to the door 8. The resilient plate 91 extends from the lower horizontal edge 8 of the door and is further arranged to contact the floor of the opening 2 when the door is in the closed position C. The resilient plate 91 deforms upon contact with the floor when the door 8 is closed, thereby protecting the door 8 from the impact and abrasion caused by direct contact with the floor. Furthermore, when the door is in the closed position, the resilient plate 91 can provide a sealing effect between the floor and the door. In one embodiment, the resilient plate 91 may be made of rubber.

[0106] refer to Figures 3a to 3bThe document describes in more detail the operating system for the lifting door, in which the drive unit includes two motors 11a and 11b. The first motor 11a and the second motor 11b can be arranged on the same horizontal section 9e of the door 8. The first motor and the second motor can also be arranged on the bottom horizontal section 9e of the door 8. The first motor 11a and the second motor 11b can be installed on different vertical sides of the door 8; for example, the first motor 11a can be arranged on the vertical side 7 of the door 8 near the opening, and the second motor 11b can be arranged on the vertical side 5 of the door 8 near the opening.

[0107] In one embodiment, the drive unit 10 includes at least a first motor 11a and a second motor 11b, which can be mounted on the same vertical side of the door 8. The first motor and the second motor can be arranged on the same horizontal section of the door 8. The first motor and the second motor can also be arranged on the bottom horizontal section 9e of the door 8.

[0108] In one embodiment, the first motor 11a is movably connected to the first elongated transmission member 19 via the first driven transmission member 18, and the second motor 11b is movably connected to the second elongated transmission member 19 via the second driven transmission member 18.

[0109] Preferably, the motor 11 and the drive unit 10 are arranged on the same main phase of the door 8, for example, the outer phase or the inner phase of the door 8. To protect the motor 11 and the drive unit 10, the motor and drive unit are arranged on the inner phase of the door facing inwards towards the door 8.

[0110] In one embodiment, one or more motors 11 of the drive unit 10 are DC motors 11. In a preferred embodiment, one or more motors 11 are brushless DC (BLDC) motors.

[0111] The control unit can communicate effectively with the drive unit 10. The control unit can communicate with the two motors 11a and 11b via wired or wireless communication.

[0112] The lifting door operating system 1 includes a control device 100 for controlling the lifting door operating system 1. See below for details.

The control device 100 may include one or more control units, such as electronic control units.

[0113] The control device 100 is configured to receive one or more signals from the detection device 110 for detecting door movement of the lifting door operating system 1.

The control device 100 can be configured to activate at least one brake element when activating the door's movement braking function to prevent uncontrolled door movement, thereby providing braking force by the at least one brake element abutting against the first side 7 and / or the second side 5, thus preventing door movement. The control device 100 can be configured to prevent operation of the door operating system 1 related to opening and closing the opening 2 when action is taken.

[0116] like Figure 3b As shown, the lifting door operating system 1 includes a drive unit 10, which includes a first transmission member 19 extending along a first side 7 and a second transmission member 19 extending along a second side 5. Therefore, the first elongated transmission member 19 is arranged to connect with the first frame segment 4, and the second elongated transmission member 19 is arranged to connect with the second frame segment 6. Figure 3b As shown, the drive unit 10 of the lifting door operating system 1 includes a first driven transmission member 18 arranged to cooperate with a first elongated transmission member 19 and a second driven transmission member 18 arranged to cooperate with a second elongated transmission member 19.

[0117] The control device 100 may be configured to receive one or more signals related to the detection of movement of the door connected to the first side 7, and one or more signals related to the detection of movement of the door connected to the second side 5. The control device 100 may be configured to compare the signals related to the movement of the door connected to the first side 7 and the signals related to the movement of the door connected to the second side 5; and if the difference between the movement of the door connected to the first side 7 and the movement of the door connected to the second side 5 exceeds a certain threshold, then determine that the detected door movement is related to an unexpected door movement.

[0118] The control device 100 can be configured to store information detected related to the opening and closing movement of a door during normal operation. The control device 100 can be configured to compare a signal related to door movement with the stored information detected related to the opening and closing movement of a door during normal operation; and if the difference between the detected door movement and the stored information related to door movement during normal operation exceeds a certain threshold, then it is determined that the detected door movement is related to an unexpected door movement.

[0119] The control device can be configured to control the movement of the drive unit 10, i.e., when and how the drive unit 10 and its associated motors 11a, 11b should move the door 8. The control device is arranged to receive input regarding whether the door 8 should be opened or closed. In one embodiment, the control device is arranged to receive input from one or more user interfaces, mechanical buttons, or a remote controller. In one embodiment, the control device is arranged to receive input from sensors for automatic operation of the door.

[0120] The drive unit may also include an additional motor, which will now be described in further detail.

[0121] In one embodiment (not shown), the drive unit 10 may include a third motor and a fourth motor mounted on a second horizontal segment 9 in the horizontal section and arranged to assist the first motor 11a and the second motor 11-b when moving the segmented door 8 from the closed position C to the open position O. In embodiments also having a third and fourth motor, according to one aspect of this application, these motors may also be operatively connected to a control unit 100 and arranged to be controlled by the control unit in the same manner as described above with respect to the first and second motors. In one embodiment, system 1 includes four motors and a control unit. The first motor 11a and the second motor 11b are arranged on segment 9e, and the third and fourth motors are arranged on another segment, such as segment 9c. The drive unit 10 may include a third driven transmission mounted to the door 8. The third driven transmission is movably connected to a first elongated transmission 19 for driving the third driven transmission 19 along the first elongated transmission 19. Furthermore, the drive unit may include a fourth driven transmission mounted to the door 8. The fourth driven transmission member is movably connected to the second elongated transmission member 19 for driving the fourth driven transmission member along the second elongated transmission member 19. (Refer to reference...) Figures 2a to 2c As described, the drive unit may also include guide wheels and guide rollers associated with the third driven drive and the fourth driven drive.

[0122] In one embodiment, the first motor 11a and the second motor 11b are arranged on section 9e, which, in the closed position C, is the section of the door 9 closest to the floor. However, it should be noted that section 9e could also be, for example, section 9d, which, in the closed position C, is arranged next to the section closest to the floor.

[0123] In one embodiment (not shown), the drive unit 10 may include a fifth motor and a sixth motor mounted on a third horizontal segment 9 in the horizontal segment 9 and arranged to assist the other motors 11 when moving the segment door 8 from the closed position C to the open position O.

[0124] In embodiments where motors are arranged on additional sections 9a to 9e, these motors may be arranged on each of the other sections, on each section, or on a section above section 9e.

[0125] In one embodiment, the first motor, the second motor, the third motor, or the first motor, the second motor, the third motor, and the fourth motor may be arranged on segment 9. Preferably, these motors may be arranged on the bottommost segment 9e.

[0126] In one embodiment, at least one motor 11 of the drive unit 10 is configured to brake the movement of the door 8 when the door 8 moves from the open position O to the closed position C. In another embodiment, the operating system has two motors, a first motor 11a and a second motor 11b, both configured to brake the movement of the door 8 when the door 8 moves from the open position O to the closed position C. According to one aspect of this application, if it has been determined that the detected movement of the door 8 is related to an unexpected door movement, the braking function of the first motor 11a and / or the second motor 11b can be activated.

[0127] In one embodiment, at least one motor 11 of the drive unit 10 is configured to function as a generator and charge at least one energy storage device when the door 8 moves from the open position O to the closed position C. In another embodiment, both the first motor 11a and the second motor 11b of the drive unit 10 are configured to function as generators and charge at least one energy storage device when the door 8 moves from the open position O to the closed position C. Because the weight of the door 8 forces it to move to the closed position, causing at least one motor of the drive unit to rotate, the motor can generate electricity to charge the energy storage device.

[0128] At least one motor 11 of the drive unit 10 may further include a brake. In one embodiment, both the first motor 11a and the second motor 11b include brakes. In one embodiment, the brake is an electromagnetic brake. The brake may be arranged to control / reduce the speed of the door 8 as it moves from the open position O to the closed position C. In one embodiment, the brake is arranged to prevent the door from moving at any position along the door's track between the closed and open positions. According to one aspect of this application, if it has been determined that the detected movement of the door 8 is related to accidental door movement, the brakes of the first motor 11a and / or the second motor 11b may be activated.

[0129] In one embodiment, the drive unit 10 is mounted to section 9e of the door 8, i.e., one of the plurality of horizontal and interconnected sections. A first motor 11a and a second motor 11b are arranged on the same section 9e. Preferably, the first motor 11a and the second motor 11b are arranged on different vertical sides of section 9e. Thus, each of the first motor 11a and the second motor 11b is arranged to cooperate with the first frame section 4 and the second frame section 6, respectively.

[0130] In one embodiment, the door 8 may be horizontal, or at least angled when viewed from the closed position C, with the door 8 positioned inside and above the opening 2. When moving from the closed position C to the open position O, the interconnected door segments 9 will push against each other, causing the entire door 8 to move upward. When moving from the vertical position to the horizontal position, the segments 9 will rotate and move relative to each other.

[0131] In one embodiment, when the door 8 is moved from the open position O to the closed position C, at least one of the first motor and the second motor 11 operates as a generator 11. The generator 11 rotates as the sprocket(s)(s)18 rotates. The generator 11 reduces the speed of the door 8. The generator 11, connected to an energy storage device, charges the energy storage device during movement. The energy storage device is charged by utilizing the kinetic energy of the moving door 8.

[0132] The lifting door operating system may include a transmission device mounting arrangement (not shown). The transmission device mounting arrangement is used to connect a slender transmission component 19.
