Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power supply line switching, in particular to a switching control method and a switching device. BACKGROUND

[0002] With the development of power transmission technology, power generation car technology appears. As a temporary power supply device, the power generation car can make the maintenance position power off under the condition of ensuring continuous power supply of users through secondary grid connection operation, so as to safely maintain, and switch back to the original power supply after maintenance.

[0003] In the related art, when the power grid needs to be maintained, the power generation car needs to be physically connected to the downstream of the power grid to be maintained first. The upstream of the power grid is connected to the downstream of the power grid to be maintained through a low-voltage switch. After the power generation car and the power grid are synchronized for the first time, the power generation car is connected to the power grid and the low-voltage switch is opened, so that the power generation car is connected inductively, thereby making the maintenance position power off for maintenance under the condition of ensuring normal power supply of users. After the maintenance is completed, the power generation car and the power grid need to be synchronized for the second time. The existing method is to connect the quasi-synchronization platform to the power grid through a bypass cable and a bypass switch, so that the power generation car and the power grid are synchronized for the second time. After the power generation car and the upstream of the power grid are synchronized, the low-voltage main switch is closed, and the connection between the power grid and the power generation car is disconnected, so that the original power supply of the power grid is restored. The above-mentioned method of controlling the low-voltage switch usually includes manually pulling the operation handle to open and close the switch.

[0004] However, the method of connecting the power grid through the bypass cable and the bypass switch to realize the secondary synchronization is relatively complex in construction process and is greatly limited by the site conditions. In some cases, it cannot be used. In the condition of not using the bypass cable and the bypass switch for secondary synchronization, the operation personnel directly pull the operation handle manually to open and close the switch. Since the operation personnel cannot determine whether the opening and closing conditions are met at the moment of operation and need to directly contact the operation handle, there is a certain risk. Therefore, a switching device is needed to remotely control the operation handle to open and close the switch. The existing switching device usually has an opening button and a closing button. When the button is pressed, the movement structure in the switching device drives the operation handle to run a certain distance in a specific direction to realize the opening and closing operation. In actual use of the switching device, since the operation personnel are far away from the operation handle, they cannot directly know the current opening and closing situation. The operation personnel need to go to the position of the operation handle to know the current state of the operation handle, so the degree of automation is low. If the button is directly pressed without determining the state of the operation handle, it may cause misoperation, which may cause the operation handle to move too much and damage the equipment or even endanger the personal safety of the operation personnel. SUMMARY

[0005] Therefore, it is necessary to provide a switching control method and a switching device with high automation and capable of avoiding misoperation in view of the low automation of the switching device.

[0008] receiving a switching control request;

[0009] determining whether the switching control request matches the position of the operating handle;

[0010] when the switching control request matches the position of the operating handle, the control component accepts the switching control request and controls the driving mechanism to drive the operating handle to perform switching operation according to the switching control request; when the switching control request does not match the position of the operating handle, the control component rejects the switching control request.

[0011] In some embodiments, the step of determining whether the switching control request matches the position of the operating handle comprises:

[0012] obtaining operation information associated with the switching control request, wherein the operation information comprises a first direction parameter or a second direction parameter, wherein the first direction parameter is used to control the driving mechanism to drive the operating handle to move towards the open position, and the second direction parameter is used to control the driving mechanism to drive the operating handle to move towards the closed position;

[0013] when the position of the operating handle is in the open position, if the operation information comprises the second direction parameter, the switching control request matches the position of the operating handle, otherwise, the switching control request does not match the position of the operating handle;

[0014] when the position of the operating handle is in the closed position, if the operation information comprises the first direction parameter, the switching control request matches the position of the operating handle, otherwise, the switching control request does not match the position of the operating handle.

[0015] In some embodiments, the step of controlling the driving mechanism to drive the operating handle to perform switching operation according to the switching control request comprises:

[0016] The driving mechanism is connected with the operating handle, if the opening and closing control request is an opening control request, the driving mechanism drives the operating handle to move towards the opening position, if the opening and closing control request is a closing control request, the driving mechanism drives the operating handle to move towards the closing position.

[0017] When the operating handle is detected to switch to the closing position or the opening position, the driving mechanism is separated from the operating handle.

[0018] In another aspect, the application provides a kind of opening and closing device for realizing the opening and closing control method described above, it includes driving mechanism, detection component and control component, the driving mechanism is used to drive the operating handle to open and close operation;The detection component is arranged corresponding to the operating handle, and is used to detect the position of the operating handle;The control component is electrically connected with the detection component, the control component is used to receive the opening and closing control request, and when the opening and closing control request matches the position of the operating handle, according to the opening and closing control request, the driving mechanism is controlled to drive the operating handle to open and close operation.

[0019] In some embodiments, the opening and closing device further includes a clutch mechanism, the driving mechanism is connected with the operating handle through the clutch mechanism, and the clutch mechanism is used to connect or separate the driving mechanism from the operating handle.

[0020] In some embodiments, the opening and closing device further includes a transmission assembly and a movable mechanism, the driving mechanism, the transmission assembly and the movable mechanism are connected in sequence, and the driving mechanism can drive the transmission assembly to move, so that the transmission assembly drives the movable mechanism to drive the operating handle to open or close operation.

[0021] In some embodiments, the detection component is provided with at least two, and a plurality of detection components are respectively referred to as first detection component and second detection component;When the movable mechanism is located at the first position, the first detection component is in contact with the movable mechanism, and the operating handle is located at the closing position, when the movable mechanism is located at the second position, the second detection component is in contact with the movable mechanism, and the operating handle is located at the opening position.

[0022] In some embodiments, the detection assembly comprises a mounting block, an elastic plate and a pressure sensor, the mounting block is arranged in parallel with the movement direction of the operating handle, one end of the elastic plate is connected to the side of the mounting block facing the movable mechanism, the elastic plate is arranged obliquely relative to the mounting block, and the other end of the elastic plate is away from the mounting block; the pressure sensor is arranged on the side of the mounting block corresponding to the other end of the elastic plate; and the movable mechanism abuts against the elastic plate.

[0024] In some embodiments, the driving mechanism comprises a motor and a torque sensor, the torque sensor is connected to the output shaft of the motor, and the motor is used to drive the operating handle to perform closing and opening operations.

[0025] The closing and opening control method and the closing and opening device can obtain the current state of the operating handle by detecting the position of the operating handle. The operator sends a closing and opening control request to the closing and opening device. After receiving the closing and opening control request, the detected operating handle position information is compared with the closing and opening control request. If the closing and opening control request indicates that the operation performed by the driving mechanism on the operating handle is the same as the current position of the operating handle, for example, the control request indicates that the driving mechanism drives the operating handle to perform closing operation, and the operating handle is located at the closing position, the control request matches the position of the operating handle, and the control request is not executed. If the closing and opening control request indicates that the operation performed by the driving mechanism on the operating handle is different from the current position of the operating handle, for example, the control request indicates that the driving mechanism drives the operating handle to perform closing operation, and the operating handle is located at the opening position, the control request does not match the position of the operating handle, and the control request is executed to control the driving mechanism to drive the operating handle to move to the closing position. In this way, it can be judged whether to execute the closing and opening control request according to the current position of the operating handle when the closing and opening control request is received, so as to realize remote control of the operating handle to perform closing and opening operation, and effectively avoid damage caused by excessive movement of the operating handle in a certain direction, thereby effectively improving the automation degree.

[0036] In the present application, unless specifically defined and limited otherwise, if there is a description of "mounting", "connecting", "connecting", "fixing" and the like, these terms should be broadly understood.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0037] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on another element or there can be a middle element. If an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element.

[0038] In combination Figure 1 And Figure 2 As shown, Figure 1 A flowchart of a closing and opening control method according to an embodiment of the present application is shown, Figure 2 A structural schematic diagram of a closing and opening device according to an embodiment of the present application is shown. A closing and opening control method provided by an embodiment of the present application is suitable for controlling a component (not shown in the figure) to control a driving mechanism 100 to drive an operating handle (not shown in the figure) to perform closing and opening operation, so that the operating handle switches between the closing position and the closing position, which includes the following steps:

[0039] Step S1, detecting the position of the operating handle, the position of the operating handle including the closing position and the closing position.

[0040] Step S2, receiving a closing and opening control request.

[0041] Step S3, judging whether the position of the operating handle matches the switch-on / off control request.

[0042] Step S4, when the position of the operating handle matches the switch-on / off control request, the control component accepts the switch-on / off control request and controls the driving mechanism 100 to drive the operating handle to perform the switch-on / off operation according to the switch-on / off control request; when the position of the operating handle does not match the switch-on / off control request, the control component rejects the switch-on / off control request.

[0043] Referring to Figure 1 and Figure 2 , specifically, the position of the operating handle is continuously detected to know that the operating handle is currently located at the switch-off position or the switch-on position. When the switch-on / off control request is received, the switch-on / off control request is compared with the detected position of the operating handle, and whether the switch-on / off control request matches the position of the operating handle is judged according to the preset matching information. When the switch-on / off control request matches the position of the operating handle, the control component controls the driving mechanism 100 to drive the operating handle to perform the corresponding switch-on / off operation. When the switch-on / off control request does not match the position of the operating handle, the driving mechanism 100 is not controlled to drive the operating handle to perform the switch-on / off operation. Whether the received switch-on / off instruction is executed is judged according to the current position of the operating handle, which can avoid that the movement amplitude of the operating handle in a certain direction is too large and effectively avoid the damage of the equipment caused by the misoperation.

[0044] It should be noted that when the position of the operating handle matches the switch-on / off control request, it means that the current position of the operating handle is different from the movement position indicated by the switch-on / off instruction. For example, the operating handle is located at the switch-on position, and the switch-on / off instruction indicates that the operating handle performs the switch-off operation, then they match, the control component controls the driving mechanism 100 to drive the operating handle to perform the switch-off operation. If the operating handle is located at the switch-on position, and the switch-on / off instruction indicates that the operating handle performs the switch-on operation, then they do not match, the control component rejects the switch-on / off request, so that the operating handle remains in the original position, avoiding the operating handle from continuously moving in the switch-on direction.

[0045] Through the above method, the current position of the operating handle is detected, and whether the operating handle performs the switch-on / off operation is judged according to the position of the operating handle, so as to avoid that the movement amplitude of the operating handle in a certain direction is too large and cause the damage of the equipment due to the misoperation. The state of the operating handle is not manually judged, and the automation degree is improved.

[0046] In addition, the control assembly can also be used to receive a signal sent by the synchronization detection device, so as to determine whether the current power grid and the power generation vehicle have completed synchronization, if the power grid and the power generation vehicle have not completed synchronization, steps S3 and S4 are not executed, if the power grid and the power generation vehicle have completed synchronization, when receiving the on-off control request, steps S3 and S4 are normally executed, through the above setting, it is ensured that the grid connection operation is performed under the premise that the power grid and the power generation vehicle are synchronized, and the safety of the grid connection operation can be improved.

[0047] In some embodiments, the step of determining whether the on-off control request matches the position of the operating handle comprises:

[0048] obtaining operation information associated with the on-off control request, the operation information comprising a first direction parameter or a second direction parameter, wherein the first direction parameter is used to control the driving mechanism 100 to drive the operating handle to move towards the open position, and the second direction parameter is used to control the driving mechanism 100 to drive the operating handle to move towards the closed position;

[0049] When the position of the operating handle is at the open position, if the operation information comprises the second direction parameter, the on-off control request matches the position of the operating handle, otherwise, it does not match;

[0050] When the position of the operating handle is at the closed position, if the operation information comprises the first direction parameter, the on-off control request matches the position of the operating handle, otherwise, it does not match.

[0051] Specifically, the operation information comprises one of the first direction parameter and the second direction parameter. When receiving the on-off control request, the current position of the operating handle is detected, when the operating handle is currently at the open position, if the on-off control request indicates that the operating handle moves in the closed direction, the on-off control request matches the position of the operating handle, and the operating handle is controlled to move in the closed direction, if the on-off control request indicates that the operating handle moves in the open direction, the on-off control request does not match the position of the operating handle, the on-off control request is rejected, and the operating handle remains in the original position. When the operating handle is currently at the closed position, if the on-off control request indicates that the operating handle moves in the open direction, the on-off control request matches the position of the operating handle, and the operating handle is controlled to move in the open direction, if the on-off control request indicates that the operating handle moves in the closed direction, the on-off control request does not match the position of the operating handle, the on-off control request is rejected, and the operating handle remains in the original position.

[0052] Through the above method, it can be determined whether to control the operating handle to perform the on-off operation according to the position of the operating handle, the operating handle is remotely controlled to perform the on-off operation, and the equipment is prevented from being damaged due to the operating handle moving in a certain direction with an excessively large amplitude caused by a misoperation, manual judgment of the state of the operating handle is not required, and the degree of automation is improved.

[0053] In some embodiments, the step of controlling the driving mechanism 100 to drive the operating handle to perform the opening and closing operation according to the opening and closing control request comprises:

[0054] The driving mechanism 100 is connected to the operating handle, and if the opening and closing control request is an opening control request, the driving mechanism 100 drives the operating handle to move towards the opening position, and if the opening and closing control request is a closing control request, the driving mechanism 100 drives the operating handle to move towards the closing position.

[0055] When the operating handle is detected to switch to the closing position or the opening position, the driving mechanism 100 is disconnected from the operating handle.

[0056] When the driving mechanism 100 needs to drive the operating handle, i.e. after the control component receives the opening and closing control request, the driving mechanism 100 is connected to the operating handle, and the driving mechanism 100 operates to drive the operating handle to move in a specified direction, and when the operating handle is moved to the position, the driving mechanism 100 is disconnected from the operating handle.

[0057] Since the driving mechanism 100 stops operating and is disconnected from the operating handle when the operating handle is detected to move to the closing position or the opening position, after the driving mechanism 100 is disconnected from the operating handle, the operating handle is not restricted by the driving mechanism 100, and the movement of the operating handle does not affect the driving mechanism 100. For ease of understanding, for example, the operating handle moves from the opening position to the closing position, when the operating handle moves to the closing position, the driving mechanism 100 stops operating and is disconnected from the operating handle, at this time, the power transmission line normally transmits power, when the line appears overload short circuit and other situations, the operating handle appears tripping phenomenon, since the driving mechanism 100 is in a disconnected state from the operating handle, the driving mechanism 100 does not restrict the operating handle to trip to the opening position, and the operating handle drives the driving mechanism 100 to avoid reverse operation to cause damage to the driving mechanism 100.

[0058] Through the above method, the driving mechanism 100 can be connected to the operating handle when the operating handle needs to be driven to move, so as to drive the operating handle to complete the opening and closing operation, and after the operating handle is moved to the position to complete the opening and closing operation, the driving mechanism 100 is disconnected from the operating handle, thereby avoiding the situation that the driving mechanism 100 restricts the operating handle to make the operating handle unable to normally trip, and improving the safety of the equipment in use.

[0059] On the other hand, referring to Figure 2 , Figure 2The overall structure of the opening and closing device in the embodiment of the application is shown, and the application provides an opening and closing device for implementing the opening and closing control method, which comprises a driving mechanism 100, a detection assembly 200 and a control assembly. The driving mechanism 100 is used to drive the operation handle to perform opening and closing operations. The detection assembly 200 is arranged corresponding to the operation handle and is used to detect the position of the operation handle. The control assembly is electrically connected with the detection assembly 200, and is used to receive an opening and closing control request. When the opening and closing control request matches the position of the operation handle, the control assembly controls the driving mechanism 100 to drive the operation handle to perform opening and closing operations according to the opening and closing control request.

[0060] Referring to Figure 2 and Figure 3 , the driving mechanism 100 is connected with the operation handle, and can drive the operation handle to perform opening and closing operations. The control assembly is electrically connected with the detection assembly 200 to receive the detection data of the detection assembly 200. When the control assembly receives an opening and closing control request, it is judged whether the opening and closing control request matches the position of the operation handle. When the opening and closing control request matches the position of the operation handle, the control assembly controls the driving mechanism 100 to drive the operation handle to perform opening and closing operations according to the opening and closing control request.

[0061] Through the above arrangement, the opening and closing method can be controlled, the movement amplitude of the operation handle can be effectively prevented from being too large, and the automation degree can be improved.

[0062] In combination with Figure 2 , in some embodiments, the opening and closing device further comprises a clutch mechanism 300. The driving mechanism 100 is connected with the operation handle through the clutch mechanism 300. The clutch mechanism 300 is used to connect or separate the driving mechanism 100 and the operation handle.

[0063] Referring to Figure 2 , the driving mechanism 100 is connected with one end of the clutch mechanism 300, and the operation handle is connected with the other end of the clutch mechanism 300. By controlling the clutch mechanism 300, the driving mechanism 100 and the operation handle can be connected or separated. It should be noted that the driving mechanism 100 can be directly or indirectly connected with the clutch mechanism 300, and the operation handle can be directly or indirectly connected with the clutch mechanism 300, as long as the operation handle and the driving mechanism 100 can be connected and separated. Through the above arrangement, the operation handle and the driving mechanism 100 can be connected and separated, which can ensure that the driving mechanism 100 can drive the operation handle to move, avoid limiting the tripping of the operation handle, and improve the safety of use.

[0064] Further, the clutch mechanism 300 can be an electromagnetic clutch. The response speed of the electromagnetic clutch is relatively fast, which can improve the response speed when the driving mechanism 100 and the operation handle are connected and separated.

[0065] in combination Figure 2 and Figure 5 In some embodiments, the closing device further comprises a transmission assembly 400 and a movable mechanism 500, the driving mechanism 100, the transmission assembly 400 and the movable mechanism 500 are sequentially connected, the driving mechanism 100 can drive the transmission assembly 400 to move, so that the transmission assembly 400 drives the movable mechanism 500 to drive the operating handle to perform the opening operation or the closing operation.

[0066] Referring to Figure 2 and Figure 5 The transmission assembly 400 comprises a transmission gear 410 and a rotating shaft 420, the driving mechanism 100 is connected with the rotating shaft 420 to drive the rotating shaft 420 to rotate around the center axis thereof, the transmission gear 410 is provided with a plurality of transmission gears 410, one of which is connected to the end of the rotating shaft 420 away from the driving mechanism 100, and the plurality of transmission gears 410 are sequentially engaged to form a reduction gear set. The movable mechanism 500 comprises a movable seat 510 and a rack 520, the movable seat 510 is connected with the operating handle to drive the operating handle to move, the rack 520 is engaged with another transmission gear 410, by adjusting the rotating direction of the rotating shaft 420, the moving direction of the rack 520 can be driven, so that the movable seat 510 drives the operating handle to move to the opening position and the closing position. Through the above arrangement, the driving mechanism 100 can remotely control the movement of the operating handle to make the operating handle perform the opening and closing operation, and the control precision is high and the operating handle is not easy to be damaged.

[0067] In some embodiments, the detection assembly 200 is provided with at least two, and the plurality of detection assemblies 200 are respectively referred to as a first detection assembly and a second detection assembly; when the movable mechanism 500 is located at the first position, the first detection assembly is in contact with the movable mechanism 500, and the operating handle is located at the closing position, when the movable mechanism 500 is located at the second position, the second detection assembly is in contact with the movable mechanism 500, and the operating handle is located at the opening position.

[0068] Referring to Figure 3 and Figure 4, the detection assembly 200 is provided with at least two, for the convenience of understanding, here two are taken as an example, two detection assemblies 200 are respectively recorded as a first detection assembly and a second detection assembly. In the installation, the first detection assembly is arranged at a first position, and the second detection assembly is arranged at a second position, the first position is determined according to the position of the operating handle in the closed position The position of the movable mechanism 500, the second position is determined according to the position of the operating handle in the open position The position of the movable mechanism 500. The movable mechanism 500 drives the operating handle to move, when the movable mechanism 500 contacts the detection assembly 200, the current position of the movable mechanism 500 can be obtained according to the corresponding relationship between the detection assembly 200 and the operating handle, that is, when the movable mechanism 500 contacts the first detection assembly, it can be obtained that the operating handle is located in the closed position, when the movable mechanism 500 contacts the second detection assembly, it can be obtained that the operating handle is located in the open position. Through the above setting, the detection assembly 200 does not need to be directly arranged corresponding to the operating handle, that is, the detection assembly 200 does not need to directly detect the operating handle, the position of the operating handle can be easily obtained, and the installation and detection are facilitated.

[0069] In some embodiments, the detection assembly 200 includes a mounting block 210, an elastic plate 220 and a pressure sensor (not shown in the figure), the mounting block 210 is arranged in the direction of the movement of the operating handle, one end of the elastic plate 220 is connected to the side of the mounting block 210 facing the movable mechanism 500, the elastic plate 220 is arranged inclined relative to the mounting block 210, the other end of the elastic plate 220 is away from the mounting block 210; the pressure sensor is arranged on the side of the mounting block 210 corresponding to the other end of the elastic plate 220; the movable mechanism 500 abuts against the elastic plate 220.

[0070] Referring to Figure 2 and Figure 3 , the detection assembly 200 is provided with four, two of which are arranged above with small spacing, and the other two are arranged below with small spacing. In the two detection assemblies 200 located above, the upper end of the elastic plate 220 is connected with the upper end side wall of the mounting block 210, and in the two detection assemblies 200 located below, the upper end of the elastic plate 220 is connected with the upper end side wall of the mounting block 210, forming the structure shown in the figure, so as to facilitate abutting with the movable mechanism 500. The movable mechanism 500 contacts the elastic plate 220 to extrude the elastic plate 220, so that the end of the elastic plate 220 extrudes the pressure sensor, and the current position of the movable mechanism 500 can be obtained according to the stress condition of the pressure sensor. Through the above setting, on the one hand, the position of the movable mechanism 500 can be accurately detected, the detection accuracy is improved, and the movement of the operating handle to the position is ensured; on the other hand, the elastic plate 220 can provide certain limiting effect to limit the activity range of the movable mechanism 500, so as to avoid the movement amplitude of the movable mechanism 500 being too large.

[0071] For ease of understanding, it is assumed that the active mechanism 500 is in the closed state when it is in contact with two detection assemblies 200 located above at the same time, and is in the open state when it is in contact with two detection assemblies 200 located below at the same time. Taking the upward movement of the active mechanism 500 as an example, the operating handle is in the open position, i.e. the active mechanism 500 is located below, the active mechanism 500 is in contact with two detection assemblies 200 located below, after receiving the closed control request, the active mechanism 500 moves upward, and when both of the two detection assemblies 200 located above detect the contact with the active mechanism 500, it is determined that the operating handle is closed in place. By arranging two detection assemblies 200 above and below, the active mechanism 500 is in contact with two detection assemblies 200 at the same time, which can accurately position the active mechanism 500 and the operating handle, and the limiting effect of the active mechanism 500 is improved by arranging two elastic plates 220. In some other embodiments, the detection assembly 200 located at the uppermost and the detection assembly 200 located at the lowermost can be used to detect the limit position of the active mechanism 500 (exceeding this position will cause damage to the operating handle), and when the active mechanism 500 abuts against the detection assembly 200 located at the uppermost or the detection assembly 200 located at the lowermost in the case that the other two detection assemblies 200 fail, the active mechanism 500 is controlled to stop moving to avoid damage to the operating handle caused by excessive movement of the active mechanism 500.

[0072] In some embodiments, the active mechanism 500 is provided with a clamping groove 530, and the operating handle is clamped in the clamping groove 530.

[0073] Referring to Figure 1 The clamping groove 530 is arranged on one side of the active mechanism 500, the operating handle is inserted into the clamping groove 530 and abuts against the inner wall of the clamping groove 530, so that the active mechanism 500 can drive the operating handle to move.

[0074] In some embodiments, the driving mechanism 100 includes a motor 110 and a torque sensor, the torque sensor is connected with the output shaft of the motor 110, and the motor 110 is used to drive the operating handle to open and close.

[0075] Referring to Figure 1The torque sensor is used to detect the torque of the output shaft of the motor 110. When the output shaft of the motor 110 is connected with the operating handle, the operating handle can be driven to perform the opening and closing operation. It should be noted that the operating handle is provided with a structure increasing the friction with the operating handle between the opening position and the closing position due to the design, so that the operating handle is subjected to a larger resistance when moving between the opening position and the closing position, to prevent the operating handle from moving due to the gravity and other external forces, resulting in misoperation. The closing position and the opening position are provided with a clearance, and when the operating handle moves to the closing position or the opening position, the friction force acting on the operating handle is reduced. The torque of the output shaft of the motor 110 is detected by the torque sensor, and when the motor 110 operates, the torque of the output shaft suddenly decreases, which can assist in judging that the operating handle moves to the opening position or the closing position. The above setting can improve the accuracy of detecting the position of the operating handle.

[0076] In some embodiments, the opening and closing device is further provided with a mounting frame 600, and the driving mechanism 100, the detection assembly 200 and the control assembly are all mounted on the mounting frame 600, to facilitate the installation and use. Further, the mounting frame 600 can be provided with a sliding groove or a guide rail 610, and the movable mechanism 500 is clamped in the sliding groove or is slidably connected with the guide rail 610, so that the movable mechanism 500 can move along the length direction of the sliding groove or the guide rail 610.

[0077] The technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.

[0078] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as the limitation of the patent application scope. It should be noted that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
