[0030] Embodiment 1

[0031] In order to solve the problem of low detection efficiency of a pressing plate in the prior art, the utility model provides a pressing plate device.

[0032] like Figure 1 to Figure 2 As shown, the pressing plate device includes a housing 10, a pressing plate 20, an action mechanism and a detection mechanism. The pressing plate 20 has a casting position and a retracting position. At least a part of the action mechanism is installed inside the housing 10. At least another part of the action mechanism extends out of the housing 10 and is drivingly connected to the pressing plate 20. The action mechanism is movably connected to the housing 10. The action mechanism provides a driving force for the pressing plate 20 to switch between the casting position and the retracting position. The action mechanism has an extended state and a retracted state. When the action mechanism is in the retracted state, the pressing plate 20 is in the casting position or the retracted position. The detection mechanism is installed inside the housing 10. The detection mechanism at least includes a micro switch and a sensor detection module. The micro switch is used to detect whether the action mechanism is in the extended state or the retracted state, and a travel switch 410. The travel switch 410 is installed inside the housing 10; wherein, when the pressing plate 20 is in the casting position, the sensor detection module sends a casting signal, and at least a part of the action mechanism abuts against the travel switch 410 to trigger the travel switch 410; when the pressing plate 20 is in the retracted position, the sensor detection module sends a retracting signal, and the action mechanism and the travel switch 410 are spaced apart.

[0033] Specifically, the detection mechanism is provided with a micro switch and a sensor detection module, so that when the action mechanism drives the pressing plate 20 to switch between the casting position and the retracted position, the micro switch can detect whether the action mechanism is in the extended state or the retracted state, and the position of the action mechanism can be detected according to the signal feedback of the micro switch; the sensor detection module can detect the casting and retracting position of the pressing plate 20 to achieve the technical effect of double detection. The technical effect of double detection effectively improves the detection accuracy and detection efficiency, and improves the safety of using the pressing plate device. At the same time, by setting the travel switch 410 to achieve that when the pressing plate 20 is in the casting position, the travel switch 410 is triggered and sends a signal to the outside world that the pressing plate 20 is in the casting position, thereby realizing the information transmission of the position of the pressing plate 20, and conveniently determining the position of the pressing plate.

[0034] Furthermore, the pressure plate 20 includes a pressure plate base 220 and a pressure plate handle 210. The pressure plate handle 210 is movably connected to the pressure plate base 220, and the driving assembly is drivingly connected to the pressure plate handle 210. When the pressure plate 20 is in the projection position, the pressure plate handle 210 is located inside the pressure plate base 220; when the pressure plate 20 is in the retracted position, the pressure plate handle 210 is located outside the pressure plate base 220.

[0035] It should be noted that the pressure plate base 220 is fixedly connected to the shell 10, and there is a through hole on the pressure plate base 220, so that a part of the action mechanism passes through the through hole and is driven and connected to the pressure plate handle 210. The action mechanism can drive the pressure plate handle 210 to switch the position, thereby realizing the switching of the pressure plate 20 between the insertion position and the retracted position.

[0036] Furthermore, when the action mechanism drives the pressure plate handle 210 to move to the outside of the pressure plate base 220, the action mechanism is in an extended state, and the action mechanism triggers the micro switch to stop the action mechanism from extending; when the action mechanism drives the pressure plate handle 210 to move to the inside of the pressure plate base 220, the action mechanism is in a retracted state, and the action mechanism triggers the micro switch to stop the action mechanism from retracting; the sensor detection module cooperates with the action mechanism to send a throw signal or a retract signal, and identifies the position of the pressure plate 20 according to the state of the micro switch and the signal received from the sensor detection module.

[0037] Furthermore, when the action mechanism drives the pressing plate 20 to be in the casting position, the action mechanism triggers the travel switch 410, and the travel switch 410 is used to control the transmission of the casting signal to the outside.

[0038] In this embodiment, two trigger ends of the micro switch are provided to detect the transmission shaft 330 in different positions, and the state of the action mechanism is detected by detecting the position of the transmission shaft 330 .

[0039] like Figure 1 to Figure 2 As shown, the action mechanism includes a driving assembly, a transmission shaft 330 and a trigger structure. The driving assembly is installed inside the shell 10, and the driving assembly is connected to the transmission shaft 330. One end of the transmission shaft 330 passes through the shell 10 and extends to the outside of the shell 10 and is connected to the pressure plate 20. The transmission shaft 330 is movably connected to the shell 10. The trigger structure is installed on the transmission shaft 330. The driving assembly drives the pressure plate 20 to the throwing position or the retracting position through the transmission shaft 330. The trigger structure is in contact with the micro switch or is spaced apart. The trigger structure cooperates with the sensor detection module so that the sensor detection module sends a throwing signal or a retracting signal.

[0040] Specifically, the transmission shaft 330 passes through the through holes on the shell 10 and the pressure plate base 220 to achieve a driving connection with the pressure plate handle 210. The driving assembly can drive the pressure plate handle 210 to adjust its position through the transmission shaft 330. A trigger structure is set on the transmission shaft 330 to trigger or release the micro switch during the rotation of the transmission shaft 330, and the trigger structure of the transmission shaft 330 cooperates with the sensor detection module induction.

[0041] Furthermore, the driving assembly includes a throwing and retracting motor 310 and a rotating motor 320. The throwing and retracting motor 310 is drivingly connected to the transmission shaft 330. The throwing and retracting motor 310 drives the pressure plate handle 210 of the pressure plate 20 to move axially along the transmission shaft 330 through the transmission shaft 330, and the rotating motor 320 drives the pressure plate handle 210 to move circumferentially along the transmission shaft 330 through the transmission shaft 330.

[0042] When the pressure plate handle 210 needs to be switched from the inside to the outside of the pressure plate base 220, the insertion and retraction motor 310 drives the transmission shaft 330 to move axially so that the pressure plate handle 210 moves to the outside of the pressure plate base 220 and is spaced apart from the pressure plate base 220. After the transmission shaft 330 moves to the preset position, the trigger structure triggers the micro switch. At this time, the action mechanism is in the extended state, and the micro switch feedback signal is used to stop the insertion and retraction motor 310 from driving the transmission shaft 330 to extend and move; the rotary motor 320 drives the transmission shaft 330 to rotate, thereby driving the pressure plate handle 210 to rotate to move out of the pressure plate base 220. The insertion and retraction motor 310 drives the transmission shaft 330 to move axially in the opposite direction so that the pressure plate handle 210 abuts against the pressure plate base 220. At this time, the trigger structure triggers the micro switch, the action mechanism is in the retraction state, and the micro switch feedback signal is used to stop the insertion and retraction motor 310 from driving the transmission shaft 330 to extend and move, thereby realizing the switching of the pressure plate 20 from the insertion position to the retraction position.

[0043] Conversely, when the pressure plate handle 210 needs to be switched from the outside to the inside of the pressure plate base 220, the insertion and retraction motor 310 drives the transmission shaft 330 to move axially so that the pressure plate handle 210 moves to the outside of the pressure plate base 220 and is spaced apart from the pressure plate base 220. After the transmission shaft 330 moves to the preset position, the trigger structure triggers the micro switch. At this time, the action mechanism is in the extended state, and the micro switch feedback signal is used to stop the insertion and retraction motor 310 from extending and moving; the rotating motor 320 drives the transmission shaft 330 to rotate, thereby driving the pressure plate handle 210 to rotate by a preset angle. The insertion and retraction motor 310 drives the transmission shaft 330 to move axially in the opposite direction so that the pressure plate handle 210 enters the pressure plate base 220. At this time, the trigger structure triggers the micro switch, the action mechanism is in the retraction state, and the micro switch feedback signal is used to stop the insertion and retraction motor 310 from moving, thereby realizing the switching of the pressure plate 20 from the retraction position to the insertion position.

[0044] In order to ensure that the pressing plate 20 remains in the casting position and the retracting position, and to enable the casting and retracting motor 310 and the rotating motor 320 to drive the transmission shaft 330, the pressing plate device further includes a locking member, which is drivingly connected to the rotating motor 320. The locking member has a locking end and a driving end. The locking end is used to lock or unlock the transmission shaft 330, and the driving end is used to drive the transmission shaft 330 to rotate. Among them, a gear 70 is provided on the transmission shaft 330. When the pressing plate 20 is in the casting position or the retracting position, the locking end of the locking member abuts against the end face of the gear 70, so that the transmission shaft 330 cannot move axially.

[0045] Furthermore, the locking member is sleeved on the driving shaft of the rotary motor 320, the driving end is an annular rack, and the locking end is a protrusion.

[0046] When the position of the pressure plate 20 needs to be switched, the rotary motor 320 drives the locking member to rotate so that the locking end of the locking member releases the locking transmission shaft 330 . When the retracting motor 310 drives the transmission shaft 330 to a preset position, the rack meshes with the gear 70 .

[0047] Furthermore, the trigger structure includes a trigger arm, which is in contact with or spaced apart from the micro switch. When the trigger arm follows the axial movement and rotation of the transmission shaft 330, the trigger arm can be released from the micro switch to trigger the micro switch, thereby realizing the feedback of the status information of the action mechanism.

[0048] In this embodiment, the micro switch includes a first trigger switch and a second trigger switch. The first trigger switch and the second trigger switch are arranged axially spaced apart along the transmission shaft 330. When the action mechanism is in an extended state, the trigger arm contacts the first trigger switch; when the action mechanism is in a retracted state, the trigger arm contacts the second trigger switch.

[0049] Further, the trigger structure includes a protrusion disposed on the transmission shaft 330 , and the protrusion abuts against or is spaced apart from the travel switch 410 . When the pressing plate 20 is in the casting position, the protrusion abuts against the travel switch to trigger the travel switch 410 .

[0050] like Figure 1 to Figure 2 As shown, the sensor detection module is a photoelectric sensing element, which includes an infrared emitting terminal 421 and an infrared receiving terminal 422 that are spaced apart. The transmission shaft 330 is accommodated in the area between the infrared emitting terminal 421 and the infrared receiving terminal 422. The trigger structure includes a through hole set on the transmission shaft 330, and the extension direction of the through hole is colinear with the connection line between the infrared emitting terminal 421 and the infrared receiving terminal 422. The infrared emitting terminal 421 emits infrared light toward the infrared receiving terminal 422 through the through hole or the side wall of the transmission shaft 330 blocks the infrared light.

[0051] Specifically, the infrared transmitting end 421 and the infrared receiving end 422 are respectively arranged on both sides of the transmission shaft 330. When the pressure plate 20 is in one of the projecting position and the retracted position, infrared light can be emitted by the infrared transmitting end 421 and passed through the through hole and then received by the infrared receiving end 422. At this time, the sensor detection module sends a corresponding projecting signal. When the pressure plate 20 is in the other of the projecting position and the retracted position, the through hole is misaligned with the direction of the infrared light, and the side wall of the transmission shaft 330 blocks the infrared light, so that the infrared receiving end 422 cannot receive the infrared light.

[0052] In this embodiment, the pressure plate device also includes a printed circuit board, a communication chip, a single-chip microcomputer and a power socket 60. The printed circuit board is installed inside the shell 10, the communication chip is installed on the printed circuit board, the single-chip microcomputer is installed on the printed circuit board, the single-chip microcomputer is electrically connected to the communication chip, the detection mechanism, the action mechanism, and the travel switch, and the power socket 60 is installed on the shell 10, and the power socket 60 is electrically connected to the single-chip microcomputer.

[0053] Specifically, a power socket 60 is provided on the shell 10 to provide power to the pressure plate device by means of an external power supply, and an electrical connection with the communication chip, the action mechanism and the detection mechanism is realized through the single-chip microcomputer, so as to export the status information of the pressure plate 20, wherein the communication chip can realize signal connection with the external terminal equipment.

[0054] Furthermore, the single chip microcomputer adopts AVRmega48 single chip microcomputer, and the communication chip is RS485 communication chip.

[0055] Furthermore, the pressure plate device also includes an external interface 80, which is arranged on the shell 10. The external interface 80 is an input and output interface. The input and output interface socket includes 2 inputs and 1 group of outputs, which is mainly used to connect other protection and measurement and control devices or other terminal equipment, so that the remote control contacts of other protection and measurement and control devices can directly remotely control the pressure plate device to unlock and retract operations, and the pressure plate operation results can be confirmed by collecting the opening and output status of the pressure plate device.

[0056] Furthermore, the pressing plate device further includes a capacitor 50, which is mounted on a printed circuit board and electrically connected to the single-chip computer. When the pressing plate device loses power, the capacitor 50 will release the stored energy to drive the rotary motor 320 to rotate and unlock, so that the pressing plate 20 is in an unlocked state. When the pressing plate device is powered on again, it will automatically return to the state before the power failure.

[0057] Furthermore, the pressure plate device also includes an indicator light, which is electrically connected to the single-chip computer and installed on the housing 10. The indicator light is used for status display. The position of the pressure plate 20 can be observed by the color of the indicator light or whether it is illuminated, which is convenient for remote viewing.

[0058] Embodiment 2

[0059] Different from the first embodiment, in this embodiment, no through hole is provided on the transmission shaft 330, but a shielding member is used to realize the inductive cooperation between the sensor detection module and the trigger structure.

[0060] Specifically, the sensor detection module is a photoelectric sensing element, which includes an infrared emitting terminal 421 and an infrared receiving terminal 422 that are spaced apart. The transmission shaft 330 is accommodated in the area between the infrared emitting terminal 421 and the infrared receiving terminal 422. The trigger structure includes a shielding member arranged on the transmission shaft 330, and the shielding member is located at the connecting line between the infrared emitting terminal 421 and the infrared receiving terminal 422. The shielding member blocks the infrared light emitted from the infrared emitting terminal 421 toward the infrared receiving terminal 422, and the sensor detection module sends a throw signal; or the shielding member is misaligned with the connecting line between the infrared emitting terminal 421 and the infrared receiving terminal 422, and the shielding member stops blocking the infrared light, and the sensor detection module sends a retreat signal.

[0061] Furthermore, the infrared transmitting end 421 and the infrared receiving end 422 are respectively arranged on both sides of the transmission shaft 330. When the pressure plate 20 is in one of the projecting position and the retracted position, infrared light can be emitted from the infrared transmitting end 421 to the infrared receiving end 422. At this time, the shielding member on the transmission shaft 330 blocks the infrared light so that the infrared light cannot be received by the infrared receiving end 422, and the sensor detection module sends a projecting signal. When the pressure plate 20 is in the other of the projecting position and the retracted position, the connection between the shielding member and the infrared transmitting end 421 and the infrared receiving end 422 is misaligned, the shielding member stops blocking the infrared light, and the sensor detection module sends a retracting signal.
