Description

Technical Field

[0001] This invention belongs to the technical field of power systems, specifically an intelligent pressure plate control system and its operation method. Background Technology

[0002] A power switch is a very important secondary electrical device, typically installed in power line system circuits for opening and closing power lines, thus controlling the on / off state of transmission lines. A power switch with remote-controlled electric operation usually consists of a drive assembly, a transmission mechanism, and a switch assembly. The switch assembly can be automatically driven by the drive assembly and transmission mechanism to switch between active and disengaged positions.

[0003] In existing intelligent pressure plate control systems, although Chinese patent number CN201810845299.9 discloses an automatic pressure plate deployment and deployment device, it mainly employs a linear drive unit and a rotary drive unit. These units drive the linear and rotary motions of the transmission shaft, respectively, thereby achieving automatic switching of the pressure plate handle between the deployment and deployment positions. However, this device uses two drive systems to move or rotate the pressure plate. If one drive system malfunctions, the device will become unusable, resulting in poor operational stability. Furthermore, the use of two drive systems occupies a significant amount of space within the intelligent pressure plate control system, leading to a larger overall size. Summary of the Invention

[0004] The purpose of this invention is to improve the poor stability of the two-stage drive system for the pressure plate and the large size of the intelligent pressure plate control system, and to provide an intelligent pressure plate control system and its operation method.

[0005] The technical solutions for achieving the above objectives include the following:

[0006] An intelligent pressure plate control system includes a transmission mechanism, a drive assembly, a conductive base, a first housing assembly, and a pressure plate assembly. The transmission mechanism includes a first transmission assembly and a second transmission assembly. A first end of the first transmission assembly is mounted on the drive assembly, and a second end of the first transmission assembly abuts against the first end of the second transmission assembly. The second end of the second transmission assembly is mounted on the pressure plate assembly. The conductive base is sleeved around the pressure plate assembly, and the pressure plate assembly and the conductive base are in sliding fit. The intelligent pressure plate control system has an elastic element, and both ends of the elastic element abut against the conductive base and the pressure plate assembly, respectively.

[0007] The first housing assembly is sleeved on the outside of the second transmission assembly, the second transmission assembly is slidably engaged with the first housing assembly, the second transmission assembly has a first clearance groove, and the first housing assembly has a first anti-rotation rib that engages with the first clearance groove; the first transmission assembly has a first guide surface, and the second transmission assembly has a second guide surface that engages with the first guide surface.

[0008] In one embodiment, the first guide surface includes a first forward spiral surface and a first reverse spiral surface, and the second guide surface includes a second forward spiral surface and a second reverse spiral surface. The first forward spiral surface and the second forward spiral surface are in contact, and the first forward spiral surface is used to drive the second transmission component to rotate clockwise.

[0009] The first reverse spiral surface is in contact with the second reverse spiral surface, and the first reverse spiral surface is used to drive the second transmission component to rotate counterclockwise.

[0010] In one embodiment, the second forward spiral surface and the second reverse spiral surface are both located on the same end face of the second transmission component, and the second forward spiral surface and the second reverse spiral surface are staggered with each other.

[0011] In one embodiment, the first transmission component includes a first moving block, a protruding post, and a second anti-rotation rib. The first reverse spiral surface is disposed at the first end of the second anti-rotation rib, the second end of the second anti-rotation rib is mounted on the first moving block, the second anti-rotation rib extends along a first direction, and the protruding post is mounted on the first moving block.

[0012] In one embodiment, the first transmission assembly further includes a second moving block, a first spring, and an abutment block. The first positive helical surface is disposed on the second moving block, and the abutment block is mounted on the outer wall of the second moving block. The second moving block has a receiving groove, and at least a portion of the protrusion is located in the receiving groove and slides in cooperation with the second moving block. The first spring is sleeved on the outside of the protrusion, and both ends of the first spring abut against the second moving block and the first moving block, respectively.

[0013] The outer wall of the second moving block has a second clearance groove, which extends along a first direction. The second anti-rotation rib passes through the second clearance groove and cooperates with the second transmission assembly. The second anti-rotation rib is used to limit the rotation of the second moving block.

[0014] In one embodiment, the second transmission component has a third moving block, the first housing component is sleeved on the third moving block, and the third moving block is rotatably engaged with the first housing component; the first clearance groove is provided on the outer wall of the third moving block and extends along a first direction, and the effective length of the first anti-rotation rib is equal to the maximum moving distance of the second moving block.

[0015] In one embodiment, the first housing assembly has a first sleeve, and the outer wall of the first sleeve has five light guide holes, which are arranged along a first direction.

[0016] The intelligent pressure plate control system has a detection component, which includes five transmitters and five receivers. The five transmitters and five receivers are all mounted on the first housing assembly, with the five transmitters located on one side of the first sleeve and the five receivers located on the other side of the first sleeve. The five transmitters and five receivers correspond one-to-one. The light emitted by the transmitter is used to pass through one of the light guide holes and is sensed by the receiver.

[0017] In one embodiment, the outer wall of the third movable block has two sets of first through holes and two sets of second through holes, the two sets of first through holes and the second through holes being arranged opposite to each other with respect to the axis of the third movable block; the two sets of second through holes are connected, the two sets of first through holes are located on both sides of the second through holes respectively, and the first through holes and the second through holes are staggered on the outer wall of the third movable block.

[0018] The first or second through hole is respectively used to correspond to any one of the light guide holes, so that the light emitted by the transmitter can pass through the third moving block, and the position or state of the third moving block can be detected after the transmitter and receiver are connected.

[0019] In one embodiment, the conductive base includes a second sleeve and a spring assembly; the pressure plate assembly includes a rotary blade switch and a conductive needle, the first end of the rotary blade switch is mounted on the second transmission assembly, the conductive needle is mounted on the second end of the rotary blade switch, the elastic element is sleeved outside the rotary blade switch, and the two ends of the elastic element abut against the stops on the second transmission assembly and the rotary blade switch, respectively.

[0020] The second sleeve is fitted over the outside of the rotary knife switch, and the outer wall of the rotary knife switch slides in fit with the inner wall of the second sleeve. The spring assembly is installed over the second sleeve and is used to engage with the conductive needle.

[0021] This invention also proposes an operation method for an intelligent pressure plate control system, comprising the following steps:

[0022] Step 1: Start the drive assembly and drive the first transmission assembly and the second transmission assembly to move in the first direction. The second transmission assembly drives the pressure plate assembly to disconnect from the conductive base. When the second transmission assembly moves a certain distance, the first anti-rotation rib separates from the first clearance groove.

[0023] Step 2: The elastic element applies a reverse force to the second transmission assembly. The second guide surface of the second transmission assembly engages with the first guide surface of the first transmission assembly. The first guide surface drives the second transmission assembly to rotate, so that the pressure plate assembly is in a split state.

[0024] The technical solution provided by this invention has the following advantages and effects:

[0025] The elastic element has two ends that abut against the conductive base and the pressure plate assembly, respectively. The drive assembly moves the pressure plate assembly in a first direction via a transmission mechanism, thereby disengaging the pressure plate assembly from the conductive base. Due to the sliding fit between the pressure plate assembly and the conductive base, the pressure plate assembly compresses the elastic element during movement, putting it into a compressed state. When the second transmission assembly of the transmission mechanism moves in the first direction, its first clearance groove engages with the first anti-rotation rib of the first housing assembly. The first anti-rotation rib restricts the rotation of the second transmission assembly, ensuring stable movement in the first direction. When the second transmission assembly moves to a preset position, the first clearance groove separates from the first anti-rotation rib. The compressed elastic element then applies a directional force to the second transmission assembly. The second transmission assembly engages with the first transmission assembly. Since the first and second transmission assemblies are respectively provided with a first guide surface and a second guide surface, the first guide surface engages with the second guide surface to drive the second transmission assembly to rotate clockwise or counterclockwise, achieving linear and directional movement of the pressure plate assembly. Therefore, the present invention uses only one set of drive components, and improves the stability of the pressure plate assembly through the first transmission component and the second transmission component, thereby improving the problems of poor stability of the pressure plate driven by two sets of drive systems and the large size of the intelligent pressure plate control system.

[0057] To facilitate understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0058] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0059] Unless otherwise specified or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0060] It should be noted that when a component is considered "fixed" to another component, it can be directly fixed to the other component or there can be an intervening component; when a component is considered "connected" to another component, it can be directly connected to the other component or there can be an intervening component; when a component is considered "mounted" on another component, it can be directly mounted on the other component or there can be an intervening component; when a component is considered "placed" on another component, it can be directly placed on the other component or there can be an intervening component.

[0061] like Figures 1 to 11 As shown, an intelligent pressure plate control system 100 includes a transmission mechanism 10, a drive assembly 20, a conductive base 50, a first housing assembly 30, and a pressure plate assembly 40. The transmission mechanism 10 includes a first transmission assembly 11 and a second transmission assembly 13. The first end of the first transmission assembly 11 is mounted on the drive assembly 20, and the second end of the first transmission assembly 11 abuts against the first end of the second transmission assembly 13. The second end of the second transmission assembly 13 is mounted on the pressure plate assembly 40. The conductive base 50 is sleeved around the pressure plate assembly 40, and the pressure plate assembly 40 and the conductive base 50 are connected together. The base 50 is slidably fitted; the intelligent pressure plate control system 100 has an elastic element 43, the two ends of which abut against the conductive base 50 and the pressure plate assembly 40 respectively; the first housing assembly 30 is sleeved on the outside of the second transmission assembly 13, the second transmission assembly 13 is slidably fitted with the first housing assembly 30, the second transmission assembly 13 has a first clearance groove 132, and the first housing assembly 30 has a first anti-rotation rib 32 that cooperates with the first clearance groove 132; the first transmission assembly 11 has a first guide surface, and the second transmission assembly 13 has a second guide surface that cooperates with the first guide surface.

[0062] like Figures 2 to 4As shown, in this embodiment, the intelligent pressure plate control system 100 also has a second housing assembly 60, and the first housing assembly 30 is installed inside the second housing assembly 60; the drive assembly 20 includes a motor 21, a drive shaft 22, a drive block 23, and a second spring 24. The motor 21 is installed on the second housing assembly 60, and the drive shaft 22 is installed on the output end of the motor 21. The motor 21 is used to drive the drive shaft 22 to rotate. The second spring 24 is sleeved on the outside of the drive shaft 22. The drive block 23 is installed on the outer wall of the drive shaft 21 and is at least partially located within the pitch of the second spring 24. When the drive shaft 22 rotates, it drives the drive block 23 to move. The drive block 23 rubs against the elastic wire of the second spring 24 and moves back and forth between multiple pitches of the second spring 24, thereby compressing the second spring 24 and causing the second spring 24 to generate an elastic driving force. The second spring 24 abuts against the first moving block 111, and the elastic force of the second spring 24 drives the first moving block 111 to move in a first direction.

[0063] The elastic element 43 has two ends abutting against the conductive base 50 and the pressure plate assembly 40, respectively. The driving assembly 20 drives the pressure plate assembly 40 to move in the first direction through the transmission mechanism 10, thereby driving the pressure plate assembly 40 to disconnect from the conductive base 50. Since the pressure plate assembly 40 and the conductive base 50 are in sliding engagement, the pressure plate assembly 40 compresses the elastic element 43 when it moves, causing the elastic element 43 to be in a compressed state. When the second transmission assembly 13 of the transmission mechanism 10 moves in the first direction, the first clearance groove 132 of the second transmission assembly 13 engages with the first anti-rotation rib 32 of the first housing assembly 30. The first anti-rotation rib 32 is used to limit the rotation of the second transmission assembly 13, so that the second transmission assembly 13 moves stably in the first direction. When the second transmission component 13 moves to the preset position, after the first clearance groove 132 separates from the first anti-rotation rib 32, the elastic element 43 is compressed and applies a directional force to the second transmission component 13. The second transmission component 13 cooperates with the first transmission component 11. Since the first transmission component 11 and the second transmission component 13 are respectively provided with a first guide surface and a second guide surface, after the first guide surface cooperates with the second guide surface, the first guide surface is used to drive the second transmission component 13 to rotate clockwise or counterclockwise, realizing the linear motion and directional motion of the pressure plate assembly 40. Therefore, the present invention uses only one set of drive components 20, and improves the stability of the pressure plate assembly 40 through the first transmission component 11 and the second transmission component 13, thus improving the problems of poor stability of the pressure plate driven by two sets of drive systems and the large size of the intelligent pressure plate control system 100.

[0064] Furthermore, when the second transmission assembly 13 moves in the first direction, the first anti-rotation rib 32 cooperates with the first clearance groove 132, and the first anti-rotation rib 32 restricts the movement direction of the second transmission assembly 13, thereby improving the stability of the second transmission assembly 13 when moving in the first direction; after the second transmission assembly moves a certain distance, the first anti-rotation rib 32 separates from the first clearance groove 132, and the first guide surface cooperates with the second guide surface. The first guide surface and the second guide surface are used to drive the second transmission assembly 13 to rotate, and the first guide surface and the second guide surface are also used to improve the stability of the second transmission assembly 13 when rotating in the second direction.

[0065] In terms of component layout, such as Figure 3 and Figure 4 As shown, the first transmission component 11 and the second transmission component 13 are both arranged in the first direction, which is the length direction of the intelligent pressure plate control system 100. Therefore, through the cooperation between the first transmission component 11 and the second transmission component 13, the size of the intelligent pressure plate control system 100 in the width direction can be reduced, thereby making the size of the intelligent pressure plate control system 100 in the width direction smaller and realizing a more miniaturized design of the intelligent pressure plate control system 100.

[0066] To achieve clockwise or counterclockwise rotation of the drive pressure plate assembly 40. For example... Figures 5 to 9 As shown, the first guide surface includes a first forward spiral surface 125 and a first reverse spiral surface 114, and the second guide surface includes a second forward spiral surface 133 and a second reverse spiral surface 134. The first forward spiral surface 125 and the second forward spiral surface 133 are in contact, and the first forward spiral surface 125 is used to drive the second transmission component 13 to rotate clockwise; the first reverse spiral surface 114 and the second reverse spiral surface 134 are in contact, and the first reverse spiral surface 114 is used to drive the second transmission component 13 to rotate counterclockwise. When the first forward helical surface 125 engages with the second forward helical surface 133, the first forward helical surface 125 is compressed by the second forward helical surface 133. Because the first forward helical surface 125 is restricted by the first transmission assembly 11, it cannot rotate. Therefore, with the first forward helical surface 125 restricted, the second forward helical surface 133 is driven to rotate by the first forward helical surface 125, causing the second transmission assembly 13 to rotate the pressure plate assembly 40 clockwise by a certain angle. Similarly, when the first reverse helical surface 114 engages with the second reverse helical surface 134, the first reverse helical surface 114 is compressed by the second reverse helical surface 134. Because the first reverse helical surface 114 is restricted by the first transmission assembly 11, the second transmission assembly 13 causes the pressure plate assembly 40 to rotate counterclockwise by a certain angle. The initial state of the pressure plate assembly 40 is the engaged state; after rotation, the pressure plate assembly 40 is in the disengaged state.

[0067] To further enable the pressure plate assembly 40 to rotate clockwise or counterclockwise. For example... Figure 9 As shown, the second forward spiral surface 133 and the second reverse spiral surface 134 are both located on the same end face of the second transmission assembly 13, and the second forward spiral surface 133 and the second reverse spiral surface 134 are staggered. By setting the second forward spiral surface 133 and the second reverse spiral surface 134 on the same end face of the second transmission assembly 13, when the first transmission assembly 11 moves in the first direction, the first forward spiral surface 125 and the first reverse spiral surface 114 of the first transmission assembly 11 cooperate with the second forward spiral surface 133 and the second reverse spiral surface 134 respectively, further realizing the clockwise or counterclockwise rotation of the second transmission assembly 13. In this embodiment, the first forward spiral surface 125, the first reverse spiral surface 114, the second forward spiral surface 133, and the second reverse spiral surface 134 are all guide slopes, used to make the second transmission assembly 13 slide circumferentially by the compression of the first transmission assembly 11 after the first transmission assembly 11 and the second transmission assembly 13 come into contact, and drive the second transmission assembly 13 to rotate relative to the first transmission assembly 11 in the second direction.

[0068] To achieve counterclockwise rotation of the second transmission component 13. For example... Figure 5 and Figure 6 As shown, the first transmission assembly 11 includes a first moving block 111, a protrusion 112, and a second anti-rotation rib 113. A first reverse spiral surface 114 is disposed at the first end of the second anti-rotation rib 113, and the second end of the second anti-rotation rib 113 is mounted on the first moving block 111. The second anti-rotation rib 113 extends along a first direction, and the protrusion 112 is mounted on the first moving block 111. By mounting the second anti-rotation rib 113 on the first moving block 111, when the first moving block 111 moves in the first direction, it will drive the second anti-rotation rib 113 to move simultaneously. The first reverse spiral surface 114 is disposed on the second anti-rotation rib 113. When the second anti-rotation rib 113 contacts the second reverse spiral surface 134 of the second transmission assembly 13, it will drive the second transmission assembly 13 to rotate counterclockwise. This second anti-rotation rib 113 is also used to limit the rotation of the second moving block 121, thereby improving the stability of the second moving block 121 during movement. In this embodiment, the outer wall of the first moving block 111 has a limiting groove 115. The limiting groove 115 cooperates with the first limiting block of the second housing assembly 60 (not shown in the figure) to restrict the movement of the first moving block 111 in the first direction. When the first reverse spiral surface 114 abuts against the second reverse spiral surface 134, the first moving block 111 is stuck by the first limiting block, thereby driving the third moving block 131 to rotate counterclockwise.

[0069] like Figures 5 to 7As shown, the first transmission assembly 11 further includes a second moving block 121, a first spring 126, and an abutment block 122. A first positive helical surface 125 is disposed on the second moving block 121, and the abutment block 122 is mounted on the outer wall of the second moving block 121. The second moving block 121 has a receiving groove 123, at least a portion of the protrusion 112 is located in the receiving groove 123 and slides in cooperation with the second moving block 121. The first spring 126 is sleeved on the outside of the protrusion 112, and both ends of the first spring 126 abut against the second moving block 121 and the first moving block 111, respectively. By disposing of the protrusion 112 in the receiving groove 123, the first moving block 111 moves, causing the second moving block 121 to move in a first direction. Simultaneously, the first spring 126 is sleeved on the outside of the protrusion 112, with its two ends abutting against the second moving block 121 and the first moving block 111, respectively. This is because when the second transmission assembly 13 is driven to rotate clockwise for the first time, after the second moving block 121 moves to the maximum distance within the first housing assembly 30, the elastic force of the second spring 24 of the drive assembly 20 is greater than the elastic force of the elastic element 43, and the first spring 126 will not be compressed on the protrusion 112. The first positive spiral surface 125 of the second moving block 121 cooperates with the second positive spiral surface 133 of the second transmission assembly 13, and through the reverse force of the elastic element 43, the second transmission assembly 13 is driven to rotate clockwise, thereby putting the pressure plate assembly 40 in the split state. When the pressure plate assembly 40 needs to be engaged, the second transmission assembly 13 is first reset. The elastic force of the second spring 24 is greater than the sum of the elastic forces of the first spring 126 and the elastic element 43. At this time, the drive assembly 20 drives the first moving block 111 and the second moving block 121. The first moving block 111 moves to the maximum distance and squeezes the first spring 126 on the protrusion 112. At the same time, the second anti-rotation rib 113 also moves toward the second transmission assembly 13. The first reverse spiral surface 114 of the second anti-rotation rib 113 will be located in front of the first forward spiral surface 125. The first reverse spiral surface 114 contacts the second reverse spiral surface 134, thereby driving the second transmission assembly 13 to rotate counterclockwise and causing the pressure plate assembly 40 to rotate from the disengaged position back to its original position.

[0070] Furthermore, the outer wall of the second moving block 121 has a second clearance groove 124, which extends along the first direction. The second anti-rotation rib 113 passes through the second clearance groove 124 and cooperates with the second transmission assembly 13. The second anti-rotation rib 113 is used to restrict the rotation of the second moving block 121. The clearance groove 124 on the second moving block 121 is mainly used for the second anti-rotation rib 113 to pass through the second moving block 121 and simultaneously restrict the rotation of the second moving block 121 in the second direction, so that the first reverse spiral surface 114 of the second anti-rotation rib 113 cooperates with the second reverse spiral surface 134 of the second transmission assembly 13. The clearance groove structure configured in this way makes the first moving block 111 and the second moving block 121 fit together compactly, saving space. Moreover, it enables the first transmission assembly 11 to drive the second transmission assembly 13 to rotate clockwise or counterclockwise, and at the same time, it can also transmit the power of the drive assembly 20 to move the second transmission assembly 13 in the first direction.

[0071] To further prevent the second transmission assembly 13 from rotating within a certain distance, such as... Figures 8 to 10 As shown, the second transmission assembly 13 has a third moving block 131, the first housing assembly 30 has a first sleeve 36, the first sleeve 36 is fixed inside the second housing assembly 60, the first sleeve 36 is sleeved on the outside of the third moving block 131, and the third moving block 131 and the first sleeve 36 are rotatably engaged; the first clearance groove 132 is provided on the outer wall of the third moving block 131 and extends along the first direction, and the effective length of the first anti-rotation rib 32 is equal to the maximum moving distance of the second moving block 121. When the third moving block 131 moves in the first direction, the first clearance groove 132 of the third moving block 131 engages with the first anti-rotation rib 32, and the first anti-rotation rib 32 engages with the first clearance groove 132 in the second direction. However, the first anti-rotation rib 32 only restricts the rotation of the third moving block 131 in the second direction and does not hinder the movement of the third moving block 131 in the first direction. The effective length of the first anti-rotation rib 32 is equal to the maximum moving distance of the second moving block 121. When the second moving block 121 moves to the maximum distance, the abutment block 122 of the second moving block 121 will abut against the abutment portion 31 of the first housing assembly 30. At the same time, the first anti-rotation rib 32 separates from the first clearance groove 132, and the first anti-rotation rib 32 will no longer restrict the rotation of the third moving block 131 in the second direction. At this time, the drive assembly 20 will stop driving the second transmission assembly 13 to move, and the first positive spiral surface 125 of the second moving block 121 will contact the second positive spiral surface 133 of the third moving block 131.

[0072] To detect the position or state of the third moving block 131 within the first housing assembly 30. For example... Figure 11 and Figure 13As shown, the first housing assembly 30 has a first sleeve 36, and the outer wall of the first sleeve 36 has a first light guide hole 351, a second light guide hole 352, a third light guide hole 353, a fourth light guide hole 354, and a fifth light guide hole 355. The first light guide hole 351, the second light guide hole 352, the third light guide hole 353, the fourth light guide hole 354, and the fifth light guide hole 355 are arranged along a first direction. The intelligent pressure plate control system 100 has a detection assembly 70, which includes five transmitters 71 and five receivers 72. The five transmitters 71 and the five receivers 72 are all mounted on the first housing assembly 30, and the five transmitters 71 are located on one side of the first sleeve 36, while the five receivers 72 are located on the other side of the first sleeve 36. The five transmitters 71 and the five receivers 72 are arranged opposite each other with respect to the central axis of the first sleeve 36. The five transmitters 71 and the five receivers 72 correspond one-to-one. The light emitted by the transmitter 71 is used to pass through one of the light guide holes and is sensed by the receiver 72. In this embodiment, the transmitter 71 emits infrared light, which is received by the receiver 72 after passing through the light guide hole, thus enabling the detection component 70 to conduct. All five transmitters 71 are infrared lamps, and all five receivers 72 are infrared light sensors. Each transmitter 71 corresponds to one receiver 72, allowing at least five different states of the third moving block 131 to be determined, and its position and state to be deduced. By identifying the position and state of the third moving block 131, the operator can further operate the drive component 20 based on its different states. In this embodiment, the five transmitters 71 are mounted on the first circuit board 73, and the five receivers 72 are mounted on the second circuit board 74. The first circuit board 73 and the second circuit board 74 are electrically connected. The first housing assembly 30 has a mounting slot 34 for mounting either the first circuit board 73 or the second circuit board 74.

[0073] In this embodiment, the first sleeve 36 has a micro switch 80 and a third through hole 37. The micro switch 80 is used to monitor the opening or closing of the conductive base 50. The micro switch 80 is at least partially located at the third through hole 37. The outer wall of the third moving block 131 has a fourth through hole 137. The third moving block 131 has a trigger 90 located at the fourth through hole 137. When the third moving block 131 moves within the first sleeve 36, when the pressure plate assembly 40 is in the first moving position, the third through hole 37 and the fourth through hole 137 are connected, and the trigger 90 contacts the micro switch 80, so that the micro switch 80 monitors that the pressure plate assembly 40 and the conductive base 50 are in a conductive state. When the pressure plate assembly 40 is engaged, the trigger 90 and the micro switch 80 are in contact and normally conductive. When manually or remotely operated, the trigger 90 is separated from the micro switch 80, the micro switch 80 circuit is broken, and the pressure plate assembly is indirectly monitored as being in an disengaged state.

[0074] To further detect the position or state of the third moving block 131 within the first housing assembly 30. For example... Figure 11 , Figures 13 to 18 As shown, the outer wall of the third moving block 131 has two sets of first through holes 135 and two sets of second through holes 136. The two sets of first through holes 135 and second through holes 136 are arranged opposite to each other with respect to the axis of the third moving block 131. The two sets of second through holes 136 are connected, and the two sets of first through holes 135 are located on both sides of the second through holes 136 respectively. The first through holes 135 and second through holes 136 are staggered on the outer wall of the third moving block 131. The first through hole 135 or the second through hole 136 is used to correspond to any one of the light guide holes, so that the light emitted by the transmitter 71 passes through the third moving block 131, and the transmitter 71 detects the position or state of the third moving block 131 after it is connected to the receiver 72. When the intelligent pressure plate control system 100 is in the closed position, that is, the initial state, the pressure plate assembly 40 is electrically connected to the conductive base 50; at this time, the first light guide hole 351 is in the conducting state, and the infrared light emitted by the transmitter 71 passes through the first through hole 135 and the first light guide hole 351 in sequence and is directed to the receiver 72. The detection component 70 detects the state position of the third moving block 131, and the pressure plate assembly 40 is in the first moving position.

[0075] like Figures 14 to 18 As shown, when the motor 21 is started and rotates forward to drive the pressure plate assembly 40 to the second moving position, the pressure plate assembly 40 is disconnected from the conductive base 50. At this time, the third light guide hole 353 is in a conductive state. The infrared light emitted by the transmitter 71 passes through the first through hole 135 and the third light guide hole 353 in sequence and is then directed onto the receiver 72. The detection component 70 detects the state position of the third moving block 131. The conduction signal of this third light guide hole 353 drives the motor 21 to stop working, and the first forward spiral surface 125 drives the second forward spiral surface 133 to rotate clockwise by 45 degrees. At this time, the fourth light guide hole 354 is in a conductive state. The conduction signal of the fourth light guide hole 354 drives the motor 21 to reverse, driving the pressure plate assembly 40 to move from the second moving position to the first moving position. The pressure plate assembly 40 is in a stable split state, and the pressure plate assembly 40 is disconnected from the conductive base 50.

[0076] When the pressure plate assembly 40 is in the open position, the second light guide hole 352 is in the conductive state. Infrared light passes through the second light guide hole 352 and the second through hole 136 in sequence. If it is necessary to drive the pressure plate assembly 40 to close, the motor 21 rotates in the forward direction to drive the pressure plate assembly 40 to move to the third moving position and compresses the first spring 126 so that the first reverse spiral surface 114 and the second reverse spiral surface 134 cooperate. The motor 21 drives the third moving block 131 to rotate counterclockwise by 45 degrees so that the fifth light guide hole 355 is conductive. Infrared light passes through the fifth light guide hole 355 and the first through hole 135 in sequence. The electrical signal generated after the fifth light guide hole 355 is conductive drives the motor 21 to rotate in the reverse direction and moves the pressure plate assembly 40 to the closed position. The pressure plate assembly 40 is electrically connected to the conductive base 50.

[0077] After the first light guide hole 351, the second light guide hole 352, the third light guide hole 353, the fourth light guide hole 354, and the fifth light guide hole 355 are respectively turned on, different electrical signals are emitted to correspond to the five different states or positions of the third moving block 131. This allows the operator to detect the state of the third moving block 131 based on the different electrical signals, and to perform corresponding operations as needed, further controlling the pressure plate control system 100.

[0078] like Figures 2 to 4 as well as Figure 12 As shown, the conductive base 50 includes a second sleeve 51 and a spring assembly 52; the pressure plate assembly 40 includes a rotating blade 42 and a conductive needle 41. The first end of the rotating blade 42 is mounted on the second transmission assembly 13, and the conductive needle 41 is mounted on the second end of the rotating blade 42. An elastic member 43 is sleeved on the outside of the rotating blade 42, and the two ends of the elastic member 43 abut against the stop blocks 44 on the second transmission assembly 13 and the rotating blade 42, respectively. The second sleeve 51 is sleeved on the outside of the rotating blade 42, and the outer wall of the rotating blade 42 slides in cooperation with the inner wall of the second sleeve 51. The spring assembly 52 is mounted on the outside of the second sleeve 51 and is used to cooperate with the conductive needle 41. In this embodiment, the spring assembly 52 is used to connect the wire, the conductive pin 41 is used to electrically connect with the spring assembly 52, and the elastic element 43 is a spring. The elastic element 43 is sleeved on the outside of the rotary blade switch 42. When the rotary blade switch 42 is moved by the third moving block 131, the third moving block 131 will squeeze the elastic element 43 to compress the elastic element 43. The elastic element 43 has a reverse force. When the first anti-rotation rib 32 separates from the first clearance groove 132, the motor 21 is in a stopped state. The reverse force of the elastic element 43 will drive the third moving block 131 to rotate 45 degrees clockwise, further realizing the linear motion and steering motion of the rotary blade switch 42.

[0079] like Figure 3 and Figure 4 As shown, the present invention also proposes an operation method for an intelligent pressure plate control system 100, comprising the following steps:

[0080] Step 1: Start the drive assembly 20 and drive the first transmission assembly 11 and the second transmission assembly 13 to move in the first direction. The second transmission assembly 13 drives the pressure plate assembly 40 to disconnect from the conductive base 50. When the second transmission assembly 13 moves a certain distance, the first anti-rotation rib 32 separates from the first clearance groove 132.

[0081] Step 2: The elastic element 43 applies a reverse force to the second transmission assembly 13. The second guide surface of the second transmission assembly 13 cooperates with the first guide surface of the first transmission assembly 11. The first guide surface drives the second transmission assembly 13 to rotate so that the pressure plate assembly 40 is in a split state.

[0082] The intelligent pressure plate control system 100 can be operated in a simple way. Only the drive component 20 needs to be controlled to realize the closing and opening of the intelligent pressure plate control system 100. The pressure plate component 40 is relatively stable in the opening state. Moreover, the operation method is simple and easy to operate.

[0083] The working principle of the intelligent pressure plate control system 100 is as follows: the motor 21 drives the drive shaft 22 to rotate in the forward direction, the drive block 23 generates friction with the second spring 24, the elastic force of the second spring 24 is greater than the elastic force of the elastic element 43, thereby pushing the first moving block 111 to move forward. The first moving block 111 sequentially pushes the second moving block 121, the third moving block 131 and the pressure plate assembly 40 to move. The pressure plate assembly 40 moves from the first moving position to the second moving position and compresses the elastic element 43. When the motor 21 receives the electrical signal from the third light guide hole 353, the motor 21 stops working. The elastic element 43 applies a reverse force to the third moving block 131. The second positive spiral surface 133 of the third moving block 131 cooperates with the first positive spiral surface 125 of the second moving block 121, and the third moving block 131 rotates 45 degrees clockwise. The motor 21 receives the electrical signal from the fourth light guide hole 354, and the motor 21 drives the pressure plate assembly 40 back to the first moving position in the reverse direction. The pressure plate assembly 40 moves from the closed position to the open position.

[0084] Motor 21 drives drive shaft 22 to rotate in the forward direction. The elastic force of the second spring 24 is greater than the sum of the elastic force of elastic element 43 and the elastic force of the first spring 126, and squeezes the first spring 126. This pushes the first moving block 111 to move forward. The first moving block 111 pushes the second moving block 121, the third moving block 131 and the pressure plate assembly 40 to move in sequence. The pressure plate assembly 40 moves from the first moving position to the third moving position. The second reverse spiral surface 134 of the third moving block 131 cooperates with the first reverse spiral surface 114 of the first moving block 111. The third moving block 131 rotates counterclockwise by 45 degrees. Motor 21 receives the electrical signal from the fifth light guide hole 355. Motor 21 drives the pressure plate assembly 40 in the reverse direction to return to the first moving position. The pressure plate assembly 40 moves from the separated state to the joined state.
