Description

Technical Field

[0001] This invention relates to the field of transmission clutch control technology, and in particular to a clutch control method. Background Technology

[0002] Electric curtains mainly rely on the movement of a transmission belt driven by a drive device to open or close the curtains. Usually, the drive device of electric curtains mainly consists of a drive motor. If the drive motor and the transmission structure are kept in a transmission connection, the operation will be very inconvenient. The function of being able to disconnect the two at any time not only facilitates installation or debugging, but also greatly enriches the user's experience of switching between manual and electric control.

[0003] Chinese patent CN201922225446.5 discloses a transmission wheel with a clutch structure, including a wheel body and a transmission shaft passing through the wheel body and coaxial with the wheel body. The wheel body has an inner cavity, which forms an annular inner circumferential wall inside the wheel body. The transmission shaft and the inner circumferential wall of the wheel body form a clutch structure, and the outer circumferential wall of the wheel body is provided with transmission teeth. The inner cavity is recessed from one end face of the wheel body. A damping element is sleeved on the transmission shaft and is located on one side of the wheel body where the inner cavity is recessed. The inner circumferential wall of the wheel body 1 has several slots. At least one movable roller is provided in the inner cavity. A lever is provided on the transmission shaft and is located in the inner cavity. The damping element and the roller form a magnetic traction engagement. The roller can cooperate with the lever to engage in the slots.

[0004] Compared to existing transmission structures with clutch mechanisms, this invention provides a completely new clutch control method and structure in addition to magnetic attraction. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a clutch control method. This method involves rotating the input gear structure to cause the clutch mechanism to swing and engage with the output gear structure, thus transmitting rotational power. Before the electronically controlled drive mechanism stops outputting rotational power, the control mechanism slightly reverses the clutch to disengage from the output gear structure, allowing manual rotation of the output gear structure. This can be applied to electric curtains, enabling manual operation of the curtains at any time. Furthermore, based on the swinging structure of the clutch mechanism, even in the event of a sudden power outage during electronic transmission, the output gear structure can be reversed to manually disengage the clutch. This ingenious and simple operation method, when applied to electric curtains, allows users to control the curtains both electronically and manually at any time. It offers intelligent and rich functionality and a superior user experience.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A clutch control method includes: an electric transmission process: in the energized state, the control system controls the drive system to rotate, and the power is transmitted to the clutch mechanism through the input gear structure. The clutch mechanism then swings to connect with the output gear structure, thereby driving the output gear structure to rotate and complete the power output.

[0008] As a preferred embodiment, it also includes: the disconnection process caused by the stop of the electric drive process: in the energized state, before each time the control system controls the drive system to stop rotating, it first controls the drive system to slightly reverse, thereby causing the clutch mechanism to swing slightly in the opposite direction until it is disconnected from the output gear structure.

[0009] As a preferred embodiment, it also includes: manual start-up process: when the output gear structure is manually controlled to rotate actively under power-on conditions, the control system receives the manual control signal and controls the drive system to rotate in the forward direction, thereby automatically triggering the electric transmission process.

[0010] As a preferred embodiment, it also includes: manual control process when power is off: since each stop of the electric drive process will trigger a disconnection process, the output gear structure can be actively rotated by manual control when the power is off.

[0011] As a preferred embodiment, it also includes: a manual disconnection process: if a sudden power failure occurs during the electric drive process and the electric disconnection process cannot be triggered, the output gear structure can be manually controlled to actively reverse, so that the clutch mechanism can swing slightly in the opposite direction to disconnect from the output gear structure.

[0012] Preferably, the process also includes: a stroke measurement process: the total stroke L is preset in both the forward and reverse rotation of the output tooth structure. The rotation measurement mechanism monitors the rotation state of the output tooth structure and feeds it back to the control system. When the output tooth structure reaches its total stroke L, the control system controls the drive system to stop rotating.

[0013] Preferably, the input tooth structure and the output tooth structure are rotatably mounted on the gear seat, the clutch mechanism is meshed with the input tooth structure, and the clutch mechanism is oscillating to form a clutch-type meshing connection with the output tooth structure, and the oscillation axis of the clutch mechanism is concentric with the rotation axis A of the input tooth structure.

[0014] Preferably, the clutch mechanism includes a rocker arm rotatably mounted on a gear seat and a clutch tooth rotatably mounted on the rocker arm and meshing with the input gear structure; when the clutch tooth rotates, it drives the rocker arm to swing through friction, so that the clutch tooth meshes with or separates from the output gear structure.

[0015] Preferably, as the clutch teeth continue to rotate, the rocker arm swings until the clutch teeth engage with the output tooth structure and then stops swinging. At this point, the rotational power is transmitted to the output tooth structure.

[0016] Preferably, the rotation metering mechanism monitors the rotation state of the output tooth structure and feeds it back to the control system, thereby triggering the manual start-up process.

[0017] Preferably, the drive system is electrically connected to the input gear structure to provide driving force, the control system is electrically connected to the drive system to control the rotation action, rotation direction and rotation stroke of the drive system, and the control system is electrically connected to the rotation metering mechanism to receive monitoring information issued by the rotation metering mechanism.

[0018] The beneficial effects of this invention are as follows:

[0019] (1) The present invention drives the clutch mechanism to swing and engage with the output gear structure by rotating the input gear structure, thereby realizing the transmission of rotational power. The control mechanism controls the micro-reverse rotation of the drive mechanism before the electric control stops the output of rotational power to disengage the clutch mechanism from the output gear structure, so that the output gear structure can be manually rotated. That is, when applied to electric curtains, the curtains can be manually pulled at any time. Moreover, based on the swing structure of the clutch mechanism, the clutch mechanism can be manually disengaged by reversing the output gear structure when a sudden power failure occurs during the electric control transmission process. It is very ingenious and easy to operate. The clutch control method in the present invention can be applied to the field of electric curtains, which can meet the user's needs to operate the curtains by electric control and manual control at any time. It has intelligent and rich functions and a good user experience.

[0020] (2) The present invention uses a clutch mechanism that is coaxially rotatably connected to the input tooth structure. The clutch mechanism is oscillating to form a clutch connection with the output tooth structure. When the input tooth structure rotates, it drives the clutch mechanism to oscillate randomly due to the friction force inside it, thereby engaging or disengaging with the output tooth structure, thus realizing the transmission or disconnection of rotational power. The structure is ingenious and the clutch engagement relationship is highly reliable. The present invention can achieve the effect of connecting the clutch mechanism with the output tooth structure by rotating the input tooth structure. It is very ingenious and the transmission connection process is completed efficiently.

[0021] (3) The present invention provides rotation drive for the system by setting a drive mechanism, sets a control mechanism to control the rotation action, rotation angle and rotation direction of the drive mechanism, and through program input, the control mechanism controls the micro-reverse of the drive mechanism before the electronic control drive mechanism stops outputting rotational power so that the clutch mechanism swings to disconnect from the output tooth structure, thereby enabling manual rotation of the output tooth structure;

[0022] (4) The present invention can measure the rotation stroke of the output tooth structure by setting a rotation measuring mechanism. With the help of the control mechanism, the output tooth structure stops rotating after the curtain is fully drawn or fully opened. Furthermore, through the rotation monitoring of the rotation measuring mechanism, the action of manually pulling the curtain from a stationary state can be captured by the control mechanism, thereby controlling the drive mechanism to start rotating. Thus, when the power is on, manually pulling the curtain will trigger the electronic control to continue pulling the curtain, making it more automated and intelligent. Attached Figure Description

[0035] Example 1

[0036] like Figure 10 As shown, this embodiment provides a clutch control method, including:

[0037] Electric transmission process: When powered on, the control system 6 controls the drive system 5 to rotate. The power is transmitted to the clutch mechanism 4 through the input gear structure 2. The clutch mechanism 4 then swings to connect with the output gear structure 3, thereby driving the output gear structure 3 to rotate and complete the power output.

[0038] Preferably, the drive system 5 is poweredly connected to the input gear structure 2 to provide driving force, and the control system 6 is electrically connected to the drive system 5 to control the rotation action, rotation direction and rotation stroke of the drive system 5.

[0039] Preferably, the input tooth structure 2 and the output tooth structure 3 are rotatably mounted on the gear seat 1, the clutch mechanism 4 is meshed with the input tooth structure 2, and the clutch mechanism 4 is oscillating to form a clutch-type meshing connection with the output tooth structure 3, and the oscillation axis of the clutch mechanism 4 is concentric with the rotation axis A21 of the input tooth structure 2.

[0040] Preferably, the clutch mechanism 4 includes a rocker arm 41 rotatably mounted on the gear seat 1 and a clutch tooth 42 rotatably mounted on the rocker arm 41 and meshing with the input gear structure 2; when the clutch tooth 42 rotates, it drives the rocker arm 41 to swing through friction, so that the clutch tooth 42 meshes with or separates from the output gear structure 3.

[0041] Preferably, as the clutch tooth 42 continues to rotate, the swing arm 41 swings until the clutch tooth 42 engages with the output tooth structure 3 and then stops swinging. At this time, the rotational power is transmitted to the output tooth structure 3.

[0042] Preferably, it also includes: a disconnection process triggered by the cessation of the electrically controlled drive process.

[0043] When powered on, before the control system 6 controls the drive system 5 to stop rotating, it first controls the drive system 5 to slightly reverse, thereby causing the clutch mechanism 4 to swing slightly in the opposite direction until it is disconnected from the output tooth structure 3.

[0044] As a preferred option, it also includes: manual start-up process:

[0045] When the output gear structure 3 is manually controlled to rotate actively, the control system 6 receives the manual control signal and controls the drive system 5 to rotate in the forward direction, thereby automatically triggering the electric transmission process.

[0046] Preferably, the rotation state of the output tooth structure 3 is monitored by the rotating metering mechanism 7 and fed back to the control system 6, thereby triggering the manual start-up process.

[0047] Preferably, the control system 6 is electrically connected to the rotating metering mechanism 7 to receive monitoring information from the rotating metering mechanism 7.

[0048] As a preferred option, it also includes: manual control process during power outage:

[0049] Since each stop of the electric drive process will trigger a disconnection process, the output gear structure 3 can be manually controlled to rotate actively when the power is off.

[0050] As a preferred option, it also includes: a manual disconnection process:

[0051] If a sudden power outage occurs during the electric drive process, preventing the electric control from disconnecting, the clutch mechanism 4 can be slightly reversed by manually controlling the output gear structure 3 to disconnect from the output gear structure 3.

[0052] As a preferred option, it also includes: a travel measurement process:

[0053] The output tooth structure 3 has a total stroke L preset for both forward and reverse rotation. The rotation metering mechanism 7 monitors the rotation status of the output tooth structure 3 and feeds it back to the control system 6. When the output tooth structure 3 reaches its total stroke L, the control system 6 controls the drive system 5 to stop rotating.

[0054] Example 2

[0055] like Figure 1As shown, this embodiment provides a swing arm clutch structure, including: a gear seat 1; an input gear structure 2 and an output gear structure 3 rotatably mounted on the gear seat 1; and a clutch mechanism 4 poweredly connected to the input gear structure 2, as shown. Figures 2-3 As shown, the clutch mechanism 4 is oscillating to form a clutch connection with the output tooth structure 3, thereby transmitting or disconnecting power.

[0056] In this embodiment, a clutch mechanism 4 is rotatably connected to the input gear structure 2 on the same axis. The clutch mechanism 4 is oscillating to form a clutch-type meshing connection with the output gear structure 3. When the input gear structure 2 rotates, it drives the clutch mechanism 4 to oscillate to mesh with or disengage from the output gear structure 3, thereby realizing the transmission or disconnection of the rotational power input through the input gear structure 2. The structure is ingenious and the clutch engagement relationship has high reliability.

[0057] As a preferred option, such as Figure 4 As shown, the clutch mechanism 4 includes: a swing arm 41, which is rotatably mounted on the gear seat 1; and a clutch tooth 42, which is rotatably mounted on the swing arm 41. The rotational friction of the clutch tooth 42 drives the swing arm 41 to swing, so that the clutch tooth 42 engages or disengages with the output tooth structure 3.

[0058] In this embodiment, when the input tooth structure 2 rotates, it drives the clutch tooth 42 to rotate synchronously through meshing. As the clutch tooth 42 continues to rotate, the swing arm 41 swings until the clutch tooth 42 meshes with the output tooth structure 3 and then stops swinging. At this time, the rotational power is transmitted to the output tooth structure 3.

[0059] As a preferred option, such as Figure 2 As shown, the gear seat 1 is provided with an abutment part 11. When the swing arm 41 swings forward and backward to make the clutch tooth 42 mesh with the output tooth structure 3, the swing arm 41 just abuts against the abutment part 11, so that the abutment part 11 helps to limit the swing arm 41 from continuing to swing, thereby improving the stability of the meshing between the clutch tooth 42 and the output tooth structure 3.

[0060] As a preferred option, such as Figure 5 As shown, a friction part 43 is connected between the rocker arm 41 and the clutch tooth 42 to transmit the rotational power of the clutch tooth 42 to the rocker arm 41 through friction.

[0061] In this embodiment, the clutch mechanism 4 has a clutch tooth 42 rotatably mounted on its swing arm 41, and a friction part 43 is tightly connected between the clutch tooth 42 and the swing arm 41. When the input tooth structure 2 drives the clutch tooth 42 to rotate synchronously, the friction between the friction part 43 and the clutch tooth 42 and the swing arm 41 causes the swing arm 41 to swing until the clutch tooth 42 meshes with the output tooth structure 3. Thus, the clutch mechanism 4 and the output tooth structure 3 can achieve the effect of transmission connection by rotating the input tooth structure 2. This is very ingenious, and the mechanism is small and compact, making the transmission connection process highly efficient.

[0062] Preferably, the friction part 43 is configured as a friction plate sleeved on the rotating shaft C44 of the clutch tooth 42, with its lower axial part abutting against the end face of the clutch tooth 42 and its upper axial part abutting against the wall surface of the swing arm 41.

[0063] As a preferred option, such as Figure 6 As shown, the friction plate is bent along the axial direction to form a bridge shape, and a limiting groove 421 is recessed on the end face of the clutch tooth 42. The lower two ends of the friction plate are matched and accommodated in the limiting groove 421, and the top of the friction plate abuts against the swing arm 41.

[0064] In this embodiment, the arc-shaped friction plate ensures sufficient friction, and the friction is within an appropriate range through debugging and testing. This allows the friction to drive the swing arm to swing smoothly while preventing excessive sliding friction caused by excessive friction after the clutch tooth 42 meshes with the output tooth structure 3, thus extending the service life. Furthermore, the wear-resistant material selection ensures that the material matches the overall service life of the system.

[0065] Preferably, the input tooth structure 2 is engaged with the clutch tooth 42 to drive the clutch tooth 42 to rotate synchronously.

[0066] As a preferred option, such as Figure 4 As shown, the input gear structure 2 includes: a rotating shaft A21, which is rotatably connected to the gear seat 1, and the swing axis of the swing arm 41 is concentric with the rotating shaft A21; and a transmission gear 22, which is mounted on the rotating shaft A21 and meshes with the clutch gear 42.

[0067] As a preferred option, such as Figure 5 As shown, the swing arm 41 has a mounting cavity 411, and the transmission gear 22 and the clutch gear 42 are mounted side by side in the mounting cavity 411.

[0068] As a preferred option, such as Figure 4As shown, the input gear structure 2 further includes an input gear 23, which is rotatably mounted on the gear seat 1 and coaxially connected to the rotating shaft A21. The input gear 23 is also connected to the drive system 5.

[0069] Preferably, the output gear structure 3 includes: a rotating shaft B31, which is rotatably mounted on the gear seat 1; a connecting gear 32 and an output gear 33, which are vertically distributed and mounted on the rotating shaft B31, and the connecting gear 32 is engaged with the clutch mechanism 4.

[0070] Example 2

[0071] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0072] As a preferred option, such as Figure 9 As shown, it also includes: a drive system 5, which is electrically connected to the input gear structure 2 to drive the input gear structure 2 to rotate; and a control system 6, which is electrically connected to the drive system 5 to control the rotation action, rotation direction and rotation stroke of the drive system 5.

[0073] Preferably, when the control system 6 controls the drive system 5 to rotate, the power is transmitted to the clutch mechanism 4 through the input gear structure 2, and the clutch mechanism 4 swings to connect with the output gear structure 3 to drive the output gear structure 3 to rotate; before the control system 6 controls the drive system 5 to stop rotating, it controls the drive system 5 to slightly reverse so that the clutch mechanism 4 swings to disconnect from the output gear structure 3.

[0074] In this embodiment, a drive mechanism 6 provides rotational driving force to the system, and a control mechanism 7 controls the rotational action, angle, and direction of the drive mechanism 6. Through program input, the control mechanism 7 slightly reverses the drive mechanism 6 before the electronically controlled drive mechanism 6 stops outputting rotational force, causing the clutch mechanism 4 to swing until it disconnects from the output gear structure 3. Figure 3 The output tooth structure 3 can be manually rotated in this state, which means that when applied to electric curtains, the curtains can be manually pulled at any time.

[0075] It should be further noted that, in this embodiment, the optimal implementation of the clutch mechanism 4's micro-reversal endpoint state is when the swing arm swings to the position shown in the diagram. Figure 3 In this state, the swing arm rotates forward or backward to the same distance as the output tooth structure 3 to re-engage, so that the next forward or reverse action can react and start at the fastest speed, and there is no risk of re-engagement in this position.

[0076] As a reference parameter for micro-reversal, the drive mechanism 6 micro-reversal is 150ms.

[0077] The electric curtains using this embodiment can be manually pulled at any time, whether the power is on or off. When the power is on, manually pulling the curtains will automatically trigger the electronic control process, enriching the user's usage methods, making them more intelligent and convenient, and providing a better user experience.

[0078] It should be further explained that even if a power outage occurs suddenly during the automatic opening and closing of the curtains controlled by the electric control, the clutch mechanism 4 and the output tooth structure 3 are in a meshing state. However, since the clutch mechanism 4 is a movable swinging structure, it is only necessary to manually pull the curtain in the opposite direction to reverse the output tooth structure 3 and make the clutch mechanism 4 swing in the opposite direction to disengage from the output tooth structure 3 through meshing. Therefore, even if a sudden power outage occurs, this embodiment can still complete the action of the clutch mechanism 4 swinging in the opposite direction to disconnect from the output tooth structure 3.

[0079] Example 3

[0080] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0081] As a preferred option, such as Figure 8 As shown, it also includes: a rotation measuring mechanism 7 electrically connected to the control system 6. The total stroke L is preset in both forward and reverse rotation of the output tooth structure 3. The rotation measuring mechanism 7 accumulates and calculates the rotation stroke of the output tooth structure 3 and feeds it back to the control system 6 so that when the output tooth structure 3 reaches its total stroke L, the control system 6 controls the drive system 5 to stop rotating.

[0082] In this embodiment, the rotational travel of the output tooth structure 3 can be measured by setting the rotational measuring mechanism 7, and the output tooth structure 3 stops rotating after the curtain is fully drawn or fully opened, in conjunction with the control mechanism 6.

[0083] In addition, by monitoring the rotation of the measuring mechanism 7, the action of manually pulling the curtain from a stationary state can be captured by the control mechanism 6. After obtaining the hand-pulling signal, the drive mechanism 5 is controlled to start rotating in the direction of hand-pulling, so that when the power is on, manually pulling the curtain will trigger the electronic control to continue pulling the curtain, i.e., the manual pull start function.

[0084] As a preferred option, such as Figure 7As shown, the rotation metering mechanism 7 includes: a sensing element 71, a plurality of sensing elements 71 are evenly distributed on the output tooth structure 3 around its rotation axis, and the sensing elements 71 are mounted on the end face of the output tooth 33; and a counting module 72 that is magnetically engaged with the sensing elements 71 and electrically connected to the control system 6. The counting module 72 is set facing the rotation path of each sensing element 71 to count and provide feedback on the sensing elements 71 that have rotated through. The counting module 72 is mounted on the gear seat 1.

[0085] Preferably, the sensing element 71 is a permanent magnet or a grating, and the counting module 72 is a Hall element. The method of measuring the stroke using magnetic sensitive elements and magnetic induction elements is existing technology, so its principle will not be described in detail here.

[0086] In this embodiment, the sensing element 71 for transmitting the rotational stroke signal is circumferentially distributed and installed on the end face of the output tooth 33. The counting module 72 for receiving the signal transmitted by the sensing element 71 is fixedly installed in the inner cavity of the mounting box 8, which saves installation space, meets the stroke measurement needs when using the rotary drive, and has a compact overall structure.

[0087] Example 4

[0088] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0089] As a preferred option, such as Figure 9 As shown, it also includes: a control box 8, in which the gear seat 1, input gear structure 2, output gear structure 3, clutch mechanism 4, drive system 5, control system 6, and rotation metering mechanism 7 are distributed and installed; and a transmission belt 9, which is poweredly connected to the output gear structure 3 and extends out of the control box 8 to output power. The transmission belt 9 is sleeved on the output gear 33, and the curtain is connected to the transmission belt 9 to be moved by the transmission belt 9.

[0090] Preferably, the drive system 5 is horizontal and located on the left side of the control box 8, the gear seat 1 is located on the right side of the control box 8 and the input gear structure 2 and the output gear structure 3 are distributed left and right, the clutch mechanism 4 is located on the lower side of the input gear structure 2, the rotation metering mechanism 7 is located on the upper side of the output gear structure 3, and the control system 6 is located above the gear seat 1.

[0091] In this embodiment, the layout of each mechanism module within the control box 8 is compact. The control box is small and aesthetically pleasing, can be installed discreetly, is suitable for various installation conditions, and the mechanisms work well together, resulting in efficient power transmission.

[0092] It should be further explained that the drive system 5 and the input tooth structure 2 are connected by a bevel gear group for power reversal. The input tooth 23 is a bevel tooth, and the output end of the drive system 5 is provided with a bevel tooth that meshes perpendicularly with the input tooth 23.

[0093] The clutch control method of the present invention is applied to the working process of electric curtains:

[0094] (1) Electrically controlled curtains in the power-on state:

[0095] After sending an open / close signal to the curtains via the external remote control button, the control system 6 receives the signal and controls the drive system 5 to rotate. The power is transmitted to the clutch mechanism 4 via the input gear structure 2. The clutch mechanism 4 swings to engage with the output gear structure 3, thereby driving the output gear structure 3 to rotate, which in turn drives the curtains to open / close via the transmission belt 9. After sending a stop signal via the external remote control button, before the control system 6 controls the drive system 5 to stop rotating, it controls the drive system 5 to slightly reverse until the clutch mechanism 4 swings to disconnect from the output gear structure 3.

[0096] (2) Manual starter with power on:

[0097] When the curtain is pulled manually from a stationary state, the control mechanism 6 captures the hand-pulling signal and then controls the drive mechanism 5 to start rotating in the direction of the hand pull, thereby triggering the electronic control to continue pulling the curtain;

[0098] (3) Manually opening and closing the curtains during power outage:

[0099] Before the drive system 5 stops rotating, it will cause the clutch mechanism 4 to swing until it is disconnected from the output gear structure 3 by slightly reversing. Therefore, the curtains can be pulled smoothly and manually opened and closed when the power is off.

[0100] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

A clutch control method according to any one of claims 1-5, characterized in that, Also includes: Stroke measurement process: The total stroke L is preset for both forward and reverse rotation of the output tooth structure. The rotation measurement mechanism monitors the rotation status of the output tooth structure and feeds it back to the control system. When the output tooth structure reaches its total stroke L, the control system controls the drive system to stop rotating.

7. A clutch control method according to any one of claims 1-5, characterized in that, The input gear structure and the output gear structure are rotatably mounted on the gear seat. The clutch mechanism is meshed with the input gear structure, and the clutch mechanism is oscillating to form a clutch-type meshing connection with the output gear structure.

8. The clutch control method according to claim 3, characterized in that, The rotating metering mechanism monitors the rotational state of the output gear structure and feeds it back to the control system, thereby triggering the manual start-up process.

9. A clutch control method according to claim 6, characterized in that, The drive system is electrically connected to the input gear structure to provide driving force, the control system is electrically connected to the drive system to control the rotation action, rotation direction and rotation stroke of the drive system, and the control system is electrically connected to the rotation metering mechanism to receive monitoring information issued by the rotation metering mechanism.
