Technical Field

[0001] The present application belongs to the technical field of detection devices, and in particular relates to a sensor. Background Art

[0002] Gas line pressure sensors are typically used to monitor and control process gas pressure to ensure proper operation of equipment and processes. They also serve as safety devices, detecting potential pressure anomalies to prevent equipment damage or process interruptions. Therefore, pressure sensors are often equipped with a display module on top, allowing users to visually monitor current gas line pressure parameters in real time.

[0003] In actual use, current pressure sensors are installed in gas pipelines. Due to the different gas flow directions in the pipelines, the pressure sensors at the corresponding positions are installed in different directions, and the orientation of the display screen on the pressure sensor is also different, which has a negative impact on engineers' observation of the display screen and reading of data. Utility Model Content

At this time, the control module can filter the position signal according to the trigger signal to fix the orientation of the image and reduce the negative impact caused by accidental touching of the rotating component.

[0021] In the technical solution of this embodiment, a card body is set on the base, and the position of the cylinder is limited by the card body so that the cylinder is not easy to rotate relative to the base, thereby making it difficult for the cable between the circuit board and the control unit to be damaged or broken due to excessive twisting.

[0051] Gas line pressure sensors are typically used to monitor and control process gas pressure to ensure proper operation of equipment and processes. They also serve as safety devices, detecting potential pressure anomalies to prevent equipment damage or process interruptions. Therefore, pressure sensors are often equipped with a display module on top, allowing users to visually monitor current gas line pressure parameters in real time.

[0052] In actual use, current pressure sensors are installed in gas pipelines. Due to the different gas flow directions in the pipelines, the pressure sensors at the corresponding positions are installed in different directions, and the orientation of the display screen on the pressure sensor is also different, which has a negative impact on engineers' observation of the display screen and reading of data.

[0053] In view of the above problems, in order to alleviate the problem that the different orientations of the sensor's display screen have a negative impact on engineers' observation of the display screen and reading of data, the present application provides a sensor, which is equipped with a rotating part and a rotary encoder to collect the position information of the rotating part through the rotary encoder, and convert the position information into a position signal and send it to the control module; a control module is set, and the orientation of the image displayed on the display component is controlled by the control module. After the control module receives the position signal sent by the rotating part, the control module controls the rotation of the image displayed on the display component. Accordingly, the user can adjust the orientation of the image of the display component by rotating the rotating part for easy observation.

[0054] The detection device in the sensor disclosed in the embodiment of the present application may include a pressure detection device, a mass flow detection device, a liquid level detection device or other detection devices. The sensor may be, but is not limited to, a pressure sensor, a mass flow meter, a liquid level sensor, etc.

[0055] For the convenience of description, the following embodiments are described by taking the sensor 100 in some embodiments of the present application as a pressure sensor 100 as an example.

[0056] refer to Figures 2 to 4 The embodiment of the present application provides a sensor 100, comprising a base 10, a rotating member 40, a rotary encoder 50, and a display assembly 60. The base 10 is provided with a control module 20 and a detection device 30, and the detection device 30 is communicatively connected to the control module 20; the rotating member 40 is rotatably connected to the base 10; the rotary encoder 50 is provided on the base 10, and is communicatively connected to the control module 20, and the rotating portion 502 of the rotary encoder 50 is connected to the rotating member 40. The rotary encoder 50 is used to collect position information of the rotating member 40 and send a position signal to the control module 20; the display assembly 60 is provided on the base 10, and is communicatively connected to the control module 20; the control module 20 is used to control the angle of the image displayed by the display assembly 60 according to the position signal.

[0057] The base 10 refers to a structure in the sensor 100 that provides a fixed foundation for other structures. The base 10 can be used to support the rotating part 40, the rotary encoder 50, the display component 60 or other structures. The sensor 100 can also be connected to other structures through the base 10; the base 10 can be a solid block structure, a hollow box structure, a frame structure or other structures. The shape of the base 10 can be cylindrical, prismatic or other shapes; the material of the base 10 can include metal, plastic or other materials.

[0058] The control module 20 refers to a structure in the sensor 100 for controlling the detection device 30, the display component 60, the rotary encoder 50 or other electronic components. The control module 20 may include a central processing unit, a memory, an input unit, an output unit and other structures.

[0059] The detection device 30 refers to a structure in the sensor 100 for detecting corresponding physical quantities or chemical quantities. The detection device 30 may include a pressure detection device, a mass flow detection device, a liquid level detection device or other detection devices to detect pressure, mass flow, liquid level and other data; the detection device 30 is communicatively connected to the control module 20. The detection device 30 can be communicatively connected to the control module 20 through a cable, or through a wireless communication unit. The detection device 30 can also be communicatively connected to the control module 20 in other ways.

[0060] The control module 20 and the detection device 30 are both disposed in the base 10 , so that the base 10 protects the control module 20 and the detection device 30 .

[0061] The rotating part 40 refers to a structure in the sensor 100 that can rotate relative to the base 10; the shape of the rotating part 40 can be a solid cylindrical structure, a hollow cylindrical structure or a structure of other shapes; the material of the rotating part 40 can include metal, plastic or other materials.

[0062] It can be understood that the rotating member 40 can only rotate relative to the base 10 and is difficult to translate relative to the base 10 .

[0063] The rotary encoder 50 is an electrical component that converts rotational mechanical displacement into an electrical signal. The rotary encoder 50 includes a fixed portion 501 and a rotating portion 502. The rotating portion 502 can rotate relative to the fixed portion 501, and the rotary encoder 500 can convert the rotational displacement of the rotating portion 502 into an electrical signal. The rotating portion 502 of the rotary encoder 50 is connected to the rotating member 40, and the fixed portion 501 of the rotary encoder 50 can be fixed relative to the base 10. Rotation of the rotating member 40 drives the rotating portion 502 to rotate relative to the fixed portion 501, thereby enabling the rotary encoder 500 to collect rotational displacement information of the rotating member 40 and generate a position signal.

[0064] Since the fixing portion 501 of the rotary encoder 50 can be fixed relative to the base 10 , the fixing portion 501 of the rotary encoder 50 can be directly connected to the base 10 or indirectly connected to the base 10 via an intermediate structure.

[0065] The rotary encoder 50 is communicatively connected to the control module 20. The rotary encoder 50 can be communicatively connected to the control module 20 via a cable, or via a wireless communication unit. The rotary encoder 50 can also be communicatively connected to the control module 20 in other ways. The rotary encoder 50 can send the collected position signal to the control module 20.

[0066] The display component 60 refers to the structure in the sensor 100 for displaying the detection data of the detection component. The display component 60 may include an LED display, an LCD display or other display; the display component 60 is arranged on the base 10, and the display can be fixedly connected to the base 10 by bonding, welding or other means, or can be detachably connected to the base 10 by screwing, snapping or other means; the rotation of the rotating part 40 relative to the base 10 is difficult to drive the display component 60 to rotate synchronously.

[0067] The rotating member 40 can be arranged on one side of the display component 60, or it can be a ring-shaped or cylindrical structure surrounding the display component 60; for example, the rotating member 40 is a cylindrical structure surrounding the display component 60, and the rotation of the rotating member 40 relative to the base 10 is not interfered with by the display component 60.

[0068] The display component 60 is communicatively connected to the control module 20 so that the control module 20 can send image information to the display component 60 for display by the display component 60; the display component 60 can be communicatively connected to the control module 20 via a cable, or can be communicatively connected to the control module 20 via a wireless communication unit. The display component 60 can also be communicatively connected to the control module 20 in other ways.

[0069] The control module 20 is communicatively connected to the rotary encoder 50, the detection device 30 and the display component 60. The control module 20 can receive the position signal sent by the rotary encoder 50 and adjust the orientation of the image displayed on the display component 60 according to the position signal; the detection device 30 can also convert the detected data into a detection signal and send it to the control module 20. The control module 20 can send the received detection signal to the display component 60 so that the display component 60 can display the relevant data information detected by the detection device 30 for the user to observe.

[0070] When the sensor 100 provided in this embodiment is in use, the user can rotate the rotating member 40 to adjust the angle of the image displayed by the display component 60 for easy observation; after the user rotates the rotating member 40, the rotary encoder 50 collects the position information of the rotating member 40 to form a position signal, and sends the position signal to the control module 20; the control module 20 receives the position signal sent by the rotary encoder 50, and adjusts the orientation of the image displayed on the display component 60 according to the position signal, so that the image displayed on the display component 60 can rotate synchronously with the rotation of the rotating member 40 for easy observation by the user.

[0071] In this embodiment, a rotating member 40 and a rotary encoder 50 are provided to collect position information of the rotating member 40 through the rotary encoder 50, and convert the position information into a position signal and send it to the control module 20; a control module 20 is provided, and the orientation of the image displayed on the display component 60 is controlled by the control module 20. After the control module 20 receives the position signal sent by the rotating member 40, the control module 20 controls the rotation of the image displayed on the display component 60. Accordingly, the user can adjust the orientation of the image of the display component 60 by rotating the rotating member 40 for easy observation.

[0072] refer to Figures 2 to 4In some embodiments, the sensor 100 further includes a trigger device 70, which is disposed on the base 10. The trigger device 70 is communicatively connected to the control module 20 and is used to send a trigger signal to the control module 20; the display component 60 can be movably disposed on the base 10, and the display component 60 can be moved to resist or separate from the trigger device 70; the control module 20 is used to receive or filter the position signal according to the trigger signal.

[0073] The trigger device 70 refers to a device in the sensor 100 for receiving external action information and generating a trigger signal. The trigger device 70 is communicatively connected to the control module 20 to send the trigger signal to the control module 20. The trigger device 70 can be a button or other structural device.

[0074] The trigger device 70 is provided on the base 10 . The trigger device 70 can be fixedly connected to the base 10 by welding, bonding or other means, or can be detachably connected to the base 10 by screwing, clamping or other means.

[0075] The display component 60 can be movably arranged on the base 10. The display component 60 can move relatively horizontally, but is not easy to rotate relative to the base 10; a slide groove, a guide rail or other structures can be set on the base 10 to limit the displacement of the display component 60; the movement of the display component 60 can be against the trigger device 70, at which time the trigger device 70 can generate a trigger signal, and the movement of the display component 60 can also be separated from the trigger device 70, at which time the trigger device 70 can also generate a trigger signal.

[0076] It can be understood that when the display component 60 is communicatively connected to the control module 20 through a wireless communication unit, the movement of the display component 60 is not likely to interfere with the communication connection between the display component 60 and the control module 20; when the display component 60 is communicatively connected to the control module 20 through a cable, the length of the cable can be made longer and greater than or equal to the maximum activity distance of the display component 60. At this time, the movement of the display component 60 is not likely to interfere with the communication connection between the display component 60 and the control module 20.

[0077] According to different actions of the display component 60, the trigger device 70 can generate different trigger signals; for example, the display component 60 abutting against the trigger device 70 can cause the trigger device 70 to generate a first trigger signal, and the display component 60 detaching from the trigger device 70 can cause the trigger device 70 to generate a second trigger signal.

[0078] Furthermore, different actions of the display component 60 can also generate more different trigger signals; for example, the display component 60 briefly presses against the trigger device 70 and detaches (for example, presses for 1 second and detaches), which can cause the trigger device 70 to generate a third trigger signal; the display component 60 presses against the trigger device 70 and detaches for a long time (for example, presses for 5 seconds and detaches), which can cause the trigger device 70 to generate a fourth trigger signal; the display component 60 presses against the trigger device 70 twice in a short period of time and detaches (for example, presses for 0.5 seconds and detaches twice in a row), which can cause the trigger device 70 to generate a fifth trigger signal.

[0079] The control module 20 is capable of receiving different trigger signals sent by the trigger device 70 and receiving or filtering the position signal sent by the rotary encoder 50 based on the different trigger signals. When the control module 20 receives the position signal, it can control the orientation of the image displayed on the display assembly 60 based on the position signal. In this case, rotation of the rotating member 40 can adjust the angle of the image displayed on the display assembly 60. When the control module 20 filters the position signal, the control module 20 no longer receives the position signal, or receives the position signal but no longer responds to the position signal and performs an action. In this case, rotation of the rotating member 40 is unable to adjust the angle of the image displayed on the display assembly 60.

[0080] For example, after the control module 20 receives the first trigger signal for the first time, the control module 20 can receive the position signal, and after the control module 20 receives the first trigger signal for the second time, the control module 20 can filter the position signal; for example, after the control module 20 receives the first trigger signal, the control module 20 can receive the position signal, and after the control module 20 receives the second trigger signal, the control module 20 can filter the position signal.

[0081] It is understandable that the control module 20 may perform other response actions in addition to receiving or filtering position signals when receiving different trigger signals.

[0082] In this embodiment, a trigger device 70 is provided, and the trigger device 70 can send a trigger signal to the control module 20, so that the control module 20 can receive or filter the position signal according to the trigger signal; the display component 60 is movably provided on the base 10, so that the user can press the trigger device 70 by pressing the display component 60, thereby facilitating the trigger device 70 to form a trigger signal according to the pressing information; without adjusting the image orientation, the user can press the display component 60 to cause the trigger component to send a trigger signal to the control module 20. At this time, the control module 20 can filter the position signal according to the trigger signal to fix the orientation of the image and reduce the negative impact caused by accidental touching of the rotating component 40.

[0083] refer to Figure 6In some embodiments, the display assembly 60 includes a bracket 61 and a display device 62 disposed in the bracket 61 . The bracket 61 is movably disposed on the base 10 . The bracket 61 is also provided with a top cover 63 covering the display device 62 .

[0084] The bracket 61 refers to a structure in the display assembly 60 used to provide a fixed foundation for the display device 62 or other structures. The bracket 61 can be a frame structure, a box structure or a structure of other shapes. The shape of the bracket 61 can be cylindrical, prismatic or other shapes; the material of the bracket 61 can include metal, plastic or other materials.

[0085] The display device 62 refers to the structure in the display component 60 for displaying images. The display device 62 can be a display screen or other device with display function. In the display component 60, the display device 62 is communicatively connected with the control module 20 so that the control module 20 can control the image displayed by the display device 62.

[0086] The bracket 61 is provided with a top cover 63 that covers the display device 62. The top cover 63 covers the display device 62 to protect the display device 62. In order to reduce interference with the clarity of the image displayed by the display device 62, the top cover 63 can be a transparent structure. The material of the top cover 63 can include glass, acrylic or other transparent materials.

[0087] Because the display assembly 60 can move relative to the base 10, a bracket 61 and a top cover 63 are provided to support the display device 62 through the bracket 61 and enable the bracket 61 to move relative to the base 10, thereby achieving the effect of the display assembly 60 moving relative to the base 10; when in use, the user can press the top cover 63 to push the bracket 61 to move relative to the base 10, thereby making the display assembly 60 move relative to the base 10.

[0088] This embodiment provides some specific structures of the display assembly 60 so that the display assembly 60 can display images and can also move relative to the base 10 , thereby facilitating the user to press the trigger device 70 by pressing the display assembly 60 .

The first guide structure 52 and the second guide structure 611 can cooperate with each other to guide the bracket 61 to move axially along the first through hole 51, so that the bracket 61 can resist or disengage from the trigger.

[0092] The first guide structure 52 can be a slide groove, in which case the second guide structure 611 is a slider slidably connected to the slide groove; the first guide structure 52 can also be a slider protruding from the side wall of the first through hole 51, in which case the second guide structure 611 is a slide groove cooperating with the slider; the first guide structure 52 can also be a guide shaft, in which case the second guide structure 611 is a sleeve sleeved on the guide shaft; it can be understood that the first guide structure 52 and the second guide structure 611 can also be other structures that cooperate with each other, and are not limited to the above-mentioned ones.

[0093] When the rotary encoder 50 includes a fixed portion 501 and a rotating portion 502 , the first through hole 51 can penetrate the fixed portion 501 and the rotating portion 502 . At this time, since the rotating portion 502 is relatively movable and the fixed portion 501 is relatively fixed, the first guide structure 52 is provided on the fixed portion 501 .

[0094] In this embodiment, a first through hole 51 is provided on the rotary encoder 50, and the trigger is provided in the first through hole 51, so that the internal structure of the sensor 100 is more compact, thereby reducing the volume of the sensor 100; a first guide structure 52 and a second guide structure 611 are provided to limit the displacement of the display component 60 through the first guide structure 52 and the second guide structure 611, so that the display component 60 can move and press the trigger device 70.

[0095] refer to Figures 2 to 4 In some embodiments, the base 10 includes a base 11 and a cylinder 12 disposed on the base 11 . The cylinder 12 is provided with a receiving cavity 121 . The detection device 30 and the control module 20 are both accommodated in the receiving cavity 121 .

[0098] The accommodating cavity 121 refers to a spatial structure formed in the cylinder 12. The accommodating cavity 121 can be a cylindrical space, a prismatic space, or a space of other shapes. The detection device 30 and the control module 20 are both accommodated in the accommodating cavity 121 to protect the detection device 30 and the control module 20 through the cylinder 12.

[0099] It can be understood that the rotary encoder 50 and the trigger device 70 can also be located in the accommodating cavity 121 and arranged close to the rotating member 40 so as to protect the rotary encoder 50 and the trigger device 70 through the cylinder 12; at this time, the rotary encoder 50 and the trigger device 70 can be supported by structural parts at a position above the cylinder 12 close to the rotating member 40.

[0100] This embodiment provides some specific structures of the base 10, so that the base 10 includes a cylinder 12, and the detection device 30 and the control module 20 are arranged in the cylinder 12, so that the detection device 30 and the control module 20 are protected by the cylinder 12, reducing the interference that the external environment may cause to the sensor 100.

[0101] refer to Figures 2 to 4 In some embodiments, the control module 20 includes a circuit board 21 disposed on the side of the cylinder 12 away from the base 11, and the circuit board 21 is provided with a fixing portion 501 of the rotary encoder 50 and a trigger device 70, and the rotary encoder 50 and the trigger device 70 are both connected to the circuit board 21; the control module 20 also includes a control unit 22 accommodated in the accommodating cavity 121, and the circuit board 21 is communicatively connected to the control unit 22.

[0102] The circuit board 21 is the carrier of the electrical components in the control module 20, and it can also provide electrical connections and communication connections for each connected electronic component to play the role of relay transmission; the control unit 22 is a structure in the control module 20 for receiving, sending and processing signals, which may include a central processing unit, memory, input devices, output devices and other structures.

[0103] The rotary encoder 50 and the trigger device 70 are both connected to the circuit board 21, and the control unit 22 is communicatively connected to the circuit board 21, so that the rotary encoder 50 and the trigger device 70 can transmit signals to the control unit 22 through the circuit board 21; the control unit 22 can be communicatively connected to the circuit board 21 via a cable, and the control unit 22 can also be wirelessly connected to the circuit board 21; for example, a wireless communication device can be set on the circuit board 21, and the control unit 22 also includes a wireless communication device, so as to realize wireless communication connection between the control unit 22 and the circuit board 21.

[0104] The circuit board 21 can be connected to the cylinder 12 and located on the side of the cylinder 12 close to the rotating part 40. The circuit board 21 can not only transmit signals but also provide a fixed basis for structures such as the rotary encoder 50 and the trigger; the circuit board 21 can be fixedly connected to the cylinder 12 by welding, bonding or other means, or can be detachably connected to the cylinder 12 by screwing, clamping or other means; for example, the circuit board 21 is connected to the cylinder 12 by bolts and is located at the upper end of the cylinder 12.

[0105] This embodiment provides some specific structures of the control module 20 so that the rotary encoder 50 and the trigger device 70 can be connected to the control module 20, and it is also convenient for the control module 20 to exchange signals with the display component 60; at the same time, making the control module 20 include a circuit board 21 and a control unit 22 also facilitates the arrangement of the control module 20.

[0106] refer to Figures 2 to 4 In some embodiments, a wire groove 122 is provided on the side of the cylinder 12 facing the base 11 , and one end of the wire groove 122 is connected to the accommodating cavity 121 , and the other end is connected to the space outside the cylinder 12 .

[0107] The wire groove 122 refers to a groove structure opened on the cylinder 12. The wire groove 122 can be a square groove, a semicircular groove, a trapezoidal groove or a groove structure of other shapes; the number of the wire grooves 122 can be one, or two or more.

[0108] One end of the wire groove 122 is connected to the accommodating cavity 121, and the other end is connected to the space outside the cylinder 12. The wire groove 122 is used to allow the cables in the accommodating cavity 121 to extend outside the cylinder 12, so that the control module 20 can be connected to other devices outside the sensor 100 through cables, and thereby exchange data and signals.

[0109] The wire groove 122 is provided on the side of the barrel 12 facing the base 11 , that is, the wire groove 122 is located on the side of the barrel 12 away from the display assembly 60 . This arrangement can reduce interference in viewing images by cable users.

[0110] Because the sensor 100 also needs to exchange signals with other external structures, in this embodiment, a wire groove 122 is set on one side of the cylinder 12 to facilitate the extension of the cable from the inside of the cylinder 12 to the outside of the cylinder 12, thereby facilitating the sensor 100 to exchange signals with other structures.

[0111] refer to Figures 2 to 4 In some embodiments, a card body (not shown in the figure) is provided on the base 11 and is clamped in the wire groove 122.

The card body can be a part of the base 11 and be integrally formed with the base 11. The card body can also be fixedly connected to the base 11 by welding, bonding or other means. The card body can also be detachably connected to the base 11 by screwing, clamping or other means.

[0113] The card body is held in the wire groove 122 to limit the displacement of the cylinder 12 relative to the base 11 , so that the cylinder 12 can be more stably connected to the base 11 and is not easily displaced with the rotation of the rotating member 40 .

[0114] It is understandable that since the wire groove 122 is also used for cables to pass through, there can be a gap between the card body and the wire groove 122 so that the card body can cooperate with the wire groove 122 to limit the position of the cylinder 12 without affecting the extension of the cables to the outside of the cylinder 12.

[0115] In this embodiment, a card body is provided on the base 11, and the position of the cylinder 12 is limited by the card body so that the cylinder 12 is not easily rotated relative to the base 11, thereby making it difficult for the cable between the circuit board 21 and the control unit 22 to be damaged or broken due to excessive twisting.

[0116] refer to Figures 2 to 4 In some embodiments, a second through hole 111 is provided on the base 11 , one end of the second through hole 111 is connected to the accommodating cavity 121 and faces the detection device 30 , and the other end of the second through hole 111 is connected to the space outside the base 11 .

[0118] One end of the second through hole 111 is connected to the accommodating cavity 121 and faces the detection device 30 , and the other end of the second through hole 111 is connected to the space outside the base 11 , so that substances outside the base 11 can enter the second through hole 111 and be detected by the detection device 30 .

[0119] For example, taking the case where the sensor 100 is installed in a gas pipeline, the gas in the gas pipeline system can enter the second through hole 111 and the detection device 30 detects relevant data of the gas.

[0120] This embodiment provides some structures of the base 11 so that the sensor 100 can be connected to the gas path, so that the detection device 30 can detect relevant parameters of the substance flowing through.

[0121] In some embodiments, the detection device 30 includes a pressure-sensitive element. In this case, the detection device 30 may be a pressure detection device 30 , and the sensor 100 may be a pressure sensor 100 .

[0122] For example, taking the case where the sensor 100 is installed in a gas pipeline, the gas in the gas pipeline system can enter the second through hole 111 , so that the detection device 30 can detect the gas pressure of the gas in the gas pipeline.

[0123] In this embodiment, the detection device 30 is a pressure-sensitive element, that is, the sensor 100 is a pressure sensor 100. The sensor 100 can detect the air pressure in the air path and display it through the display assembly 60 for easy observation by the user.

[0124] In some embodiments, the sensor 100 includes a base 10 , a control module 20 , a detection device 30 , a rotating member 40 , a rotary encoder 50 , a display assembly 60 , and a trigger device 70 .

[0125] The base 10 includes a base 11 and a cylinder 12 fixedly connected to the base 11 . A second through hole 111 is defined in the base 11 .

[0126] The detection device 30 is a pressure detection device 30 . The detection device 30 is provided on the base 11 and located in the cylinder 12 . The detection device 30 is opposite to the through hole.

[0127] The control module 20 includes a control unit 22 disposed on the detection device 30 . The control module 20 also includes a circuit board 21 disposed on the upper end of the cylinder 12 . The circuit board 21 and the control unit 22 are communicatively connected via a cable or a flexible circuit board.

[0128] Rotating Component 40 The rotating component 40 is a cylindrical structure and is rotatably connected to the upper end of the cylinder 12 .

[0129] The fixed portion 501 of the rotary encoder 50 is electrically connected to the circuit board 21 and is located inside the rotating member 40 . The rotating portion 502 of the rotary encoder 50 is connected to the rotating member 40 . A first through hole 51 is defined on the rotary encoder 50 , and a first guide structure 52 is disposed in the first through hole 51 .

[0132] When the sensor 100 provided in this embodiment is in use, the user first presses the top cover 63 to push the bracket 61 to move along the first through hole 51 and trigger the trigger device 70. At this time, the controller receives the trigger signal sent by the trigger device 70 and can receive the position signal.

[0133] Afterwards, the user can rotate the rotating member 40 to adjust the angle of the image displayed on the display component 60 for easy observation; during the process of the user rotating the rotating member 40, the rotary encoder 50 collects the position information of the rotating member 40 to form a position signal, and sends the position signal to the control module 20; the control module 20 receives the position signal sent by the rotary encoder 50, and adjusts the orientation of the image displayed on the display component 60 according to the position signal, so that the image displayed on the display component 60 can rotate synchronously with the rotation of the rotating member 40 for easy observation by the user.

[0134] After the orientation of the image meets the user's needs, the user stops rotating the rotating member 40 and presses the top cover 63 again to push the bracket 61 to move along the first through hole 51 and trigger the trigger device 70. At this time, the control receives the trigger signal sent by the trigger device 70 and is able to filter the position signal; thereafter, the position signal formed by the position information of the rotating member 40 collected by the rotary encoder 50 will be filtered by the control module 20, and the control module 20 will no longer respond to the position information and adjust the orientation of the image displayed by the display component 60 to reduce interference with the image orientation caused by external interference, false touch, etc.
