Description

Technical Field

[0001] This application relates to the field of smart wearable device technology, specifically a smart wearable electrical equipment control device. Background Technology

[0002] Currently, intelligent wearable control devices are widely used in the inspection, maintenance, and operation of electrical equipment. Existing intelligent wearable electrical equipment control devices typically consist of a processing chip, an image acquisition component, a near-eye display component, a wearing frame, and a control module. Their working principle is mainly to collect real-time operating information of field equipment such as power distribution cabinets and electrical components through the image acquisition component, transmit the information to the processing chip for analysis and processing, and then feed the data, images, and other information directly back to the operator's eyes through the near-eye display component, so as to realize close-range, visual control and maintenance of electrical equipment.

[0003] However, traditional wearable devices only use a single near-eye display mode for information output. This means that during actual maintenance work, operators need to observe both physical devices such as nearby power distribution cabinets and electrical components, as well as the near-eye display screen in front of them. The human eye has to repeatedly adjust its focus between two near-distance targets, namely physical devices and the near-eye screen. The eyes are in a state of fatigue due to frequent contraction and relaxation for a long time, which can easily lead to visual fatigue, dizziness and other discomfort symptoms, thus affecting the quality and efficiency of long-term maintenance work.

[0004] Therefore, this application provides a smart wearable electrical equipment control device to solve the above problems. Summary of the Invention

[0005] This application provides an intelligent wearable electrical equipment control device, which aims to solve the problems mentioned in the background art, such as the existing wearable electrical equipment control devices only adopting a single near-eye display mode, which requires the operator's eyes to repeatedly adjust the focus between the physical device and the near-eye screen, easily causing visual fatigue and dizziness, and reducing the quality and efficiency of long-term maintenance work.

[0006] To achieve the above objectives, this application provides the following technical solution: a smart wearable electrical equipment control device, including a processing chip, a frame, a camera fixedly connected to one side of the frame for collecting information, and a virtual display screen set on the camera for feeding back information to the user's eyes; The electrical equipment control device also includes a micro projector fixedly installed on the side of the virtual display screen away from the camera for projecting display information, and a switching structure installed on the camera for switching between the virtual display screen and the micro projector; The switching structure is equipped with a focusing structure connected to the micro projector for focusing the micro projector. The camera is connected to the input terminal of the processing chip, and the virtual display screen, micro projector, and switching structure are all connected to the output terminal of the processing chip. The focusing structure is bidirectionally connected to the processing chip. By collecting on-site information through the camera and transmitting it to the processing chip, the switching structure enables mode switching between the virtual display screen and the micro projector. This allows for near-eye information display through the virtual display screen and long-distance projection display through the micro projector, thus avoiding visual fatigue and dizziness caused by frequent focus adjustments by the human eye, thereby improving maintenance quality and comfort. At the same time, the focusing structure automatically adjusts the focus of the micro projector to ensure a clear and stable projected image, further improving visual comfort and operational convenience during electrical maintenance.

[0007] Preferably, in order to improve the wearing comfort of the device, a rubber pad for flexible contact with the head is fixedly installed on the inner side of the frame; by setting the rubber pad to make flexible contact with the head, the contact area between the frame and the head can be increased, the wearing pressure can be distributed, the squeezing and friction of the rigid frame on the head can be reduced, and the wearing comfort during long-term work can be improved.

[0008] Preferably, to facilitate the connection and use of the device with a safety helmet, the frame is fixedly connected with multiple hooks for hooking with the inner edge of the safety helmet. The multiple hooks are evenly distributed, and each hook has a threaded hole for bolt connection. By hooking and positioning the device with the inner edge of the safety helmet through the hooks, and then using the threaded holes and bolts to achieve a tight connection with the safety helmet, the device can be firmly installed on the safety helmet, improving the safety of wearing it in the industrial field.

[0009] Preferably, in order to achieve posture switching between the micro projector and the virtual display screen, the switching structure includes a driving component disposed on the camera and connected to the side of the virtual display screen away from the micro projector for driving the micro projector and the virtual display screen to switch postures, and a trigger component disposed on the driving component for opening and closing the micro projector or the virtual display screen in accordance with the posture switching; the driving component drives the virtual display screen and the micro projector to rotate and switch postures, while the trigger component automatically controls the opening and closing of the virtual display screen or the micro projector in accordance with the posture change, thereby improving the convenience and intuitiveness of mode switching.

[0010] Preferably, to facilitate the attitude switching between the micro projector and the virtual display screen, the driving component includes a connector mounted on the camera, a rotating shaft running longitudinally through the connector and rotatably connected to the connector, a concave frame mounted on the outside of the connector and fixedly connected to both ends of the rotating shaft, a protective box fixedly mounted on the connector and located below the rotating shaft, and an angle motor fixedly mounted inside the protective box for driving the rotating shaft to rotate. The rotating shaft is rotatably connected to the protective box, and the angle motor is connected to the output terminal of the processing chip. By installing the angle motor inside the protective box and connecting it to the processing chip, the rotating shaft is driven to rotate under the control of the processing chip, thereby driving the concave frame to complete the attitude switching, which is simple and quick.

[0011] Preferably, to achieve the linkage between posture switching and display mode activation / deactivation, the triggering component includes proximity switches one and two fixedly connected to the connecting base at positions corresponding to both ends of the rotating shaft; connecting plates one and two fixedly connected to both ends of the rotating shaft on the same side; metal plates one and two fixedly connected to connecting plates one and two for sensing and engaging with proximity switches one and two to activate the virtual display screen and micro projector; and two protective sleeves fixedly connected to the concave frame near the ends of the rotating shaft and respectively covering the outside of proximity switches one and two. The end of the protective sleeve away from the concave frame is rotatably connected to the connecting base. Proximity switches one and two are vertically arranged, and both proximity switches one and two are connected to the input terminal of the processing chip. By sensing and engaging with the corresponding proximity switches, metal plates one and two can transmit position signals to the processing chip, thereby activating and deactivating the virtual display screen and micro projector. Simultaneously, the protective sleeves provide dust protection for the proximity switches, ensuring a fast response time for display switching.

[0012] Preferably, to achieve automatic focusing of the projection, the focusing structure includes a distance sensor fixedly installed on one side of the lens of the micro projector for measuring the distance to the projection position, and a telescopic component mounted on the camera and connected to the connector for adjusting the projection distance of the micro projector. The distance sensor is connected to the input terminal of the processing chip, and the telescopic component is connected to the output terminal of the processing chip. The distance sensor detects the distance to the projection target in real time and transmits the signal to the processing chip. The processing chip controls the telescopic component to adjust the projection distance of the micro projector based on the distance data, thereby achieving automatic sharpening of the projected image and improving the clarity of the projection display at different distances.

[0013] Preferably, to achieve projection distance adjustment, the telescopic assembly includes a fixed frame fixedly connected to one side of the camera, an L-shaped frame passing through the fixed frame and slidably connected within the fixed frame, and an electric telescopic rod fixedly installed on the outside of the fixed frame and connected to the output end of the processing chip. The telescopic end of the electric telescopic rod is fixedly connected to the outside of the L-shaped frame away from the fixed frame, and the end of the L-shaped frame away from the fixed frame is fixedly connected to the side of the connecting seat away from the concave frame. Under the control of the processing chip, the electric telescopic rod drives the L-shaped frame to slide along the fixed frame, thereby causing the connecting seat and the micro projector to move back and forth as a whole. The projection distance can be changed by using linear telescopic motion, achieving smooth focus adjustment and improving projection clarity.

[0014] Preferably, in order to facilitate the adjustment of the distance between the virtual display screen and the eyes, a second distance measuring sensor for measuring the distance to the eyes is fixedly installed on the virtual display screen. The second distance measuring sensor is connected to the input terminal of the processing chip. By detecting the distance between the virtual display screen and the eyes in real time through the second distance measuring sensor and transmitting the signal to the processing chip, the distance between the virtual display screen and the eyes can be adjusted in conjunction with the telescopic component to realize intelligent adaptation of the distance between the eyes and the screen, thereby improving the viewing comfort and visual effect of near-eye display.

[0015] This intelligent wearable electrical equipment control device collects on-site information through a camera and transmits it to a processing chip. It uses a switching structure to switch between virtual display screen and micro projector modes. It can display near-eye information through the virtual display screen and project information from a distance through the micro projector, thereby avoiding visual fatigue and dizziness caused by frequent adjustment of focus by the human eye, thus improving maintenance quality and comfort. This intelligent wearable electrical equipment control device, through the setting of a focusing structure composed of a ranging sensor and a telescopic component, can automatically adjust the focus of the micro projector to ensure a clear and stable projected image, further improving the visual comfort and ease of operation during electrical maintenance. This intelligent wearable electrical device control unit uses a distance sensor to detect the distance between the virtual display screen and the eyes in real time and transmits the signal to the processing chip. It can be used with a telescopic component to adjust the distance between the virtual display screen and the eyes, realizing intelligent adaptation of the eye-screen distance and improving the viewing comfort and visual effect of near-eye displays.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Example 1 This embodiment provides a smart wearable electrical equipment control device, such as... Figures 1-6As shown, the intelligent wearable electrical device control device includes a processing chip, a frame 1, a camera 2 fixedly connected to one side of the frame 1 for collecting information, and a virtual display screen 3 set on the camera 2 for feeding information back to the user's eyes; the electrical device control device also includes a micro projector 4 fixedly set on the side of the virtual display screen 3 away from the camera 2 for projecting and displaying information, and a switching structure 5 set on the camera 2 for switching between the virtual display screen 3 and the micro projector 4; the switching structure 5 is provided with a focusing structure 6 connected to the micro projector 4 for focusing the micro projector 4, the camera 2 is connected to the input terminal of the processing chip, the virtual display screen 3, the micro projector 4 and the switching structure 5 are all connected to the output terminal of the processing chip, and the focusing structure 6 is bidirectionally connected to the processing chip.

[0020] In order to improve the wearing comfort of the device, a rubber pad 11 for flexible contact with the head is fixedly installed on the inner side of the frame 1. By setting the rubber pad 11 to make flexible contact with the head, the contact area between the frame 1 and the head can be increased, the wearing pressure can be distributed, the squeezing and friction of the rigid frame 1 on the head can be reduced, and the wearing comfort during long-term work can be improved.

[0021] In addition, to facilitate the connection and use of the device with a safety helmet, a number of hooks 12 for hooking with the inner edge of the safety helmet are fixedly connected to the frame 1. The hooks 12 are evenly distributed and have threaded holes 13 for bolt connection. The device can be firmly installed on the safety helmet by hooking and positioning with the inner edge of the safety helmet through the hooks 12 and then fastened to the safety helmet by bolts through the threaded holes 13. This improves the safety of wearing the device in the industrial field.

[0022] In use, frame 1 serves as the overall support carrier. Rubber pads 11 on the inner side of frame 1 flexibly contact the head, providing cushioning and pressure relief during wear. Multiple hooks 12 evenly distributed on frame 1 engage with the inner edge of the safety helmet for positioning, and threaded holes 13 on the hooks 12, along with bolts, secure the device, ensuring it is stably worn on the worker's head. This provides a reliable structural foundation for subsequent intelligent control. During operation, a camera 2 on one side of frame 1 captures real-time images and operational information of the electrical equipment. This information is transmitted to the input of a processing chip. The processing chip analyzes, processes, and calculates the received information, and based on preset logic and actual control requirements, controls the virtual display screen 3, the micro-projector 4, and the switching structure 5 via its output. The switching structure 5 enables mode switching and interlocking operation between the virtual display screen 3 and the micro projector 4. When near-eye display is required, the switching structure 5 switches the working mode to the virtual display screen 3, which then feeds the processed information back to the user's eyes, meeting the need for close-range fine viewing. When long-distance projection is required, the switching structure 5 switches the working mode to the micro projector 4, which projects the information onto an external wall or equipment surface. Simultaneously, the focusing structure 6 connected to the micro projector 4 has a bidirectional signal connection with the processing chip. The focusing structure 6 can collect projection distance information in real time and feed it back to the processing chip. The processing chip drives the focusing structure 6 to automatically adjust the focus of the micro projector 4 based on the distance data, ensuring that the projected image is always clear, thus adapting to different work scenarios such as electrical equipment maintenance and operation.

[0023] Specifically, the switching structure 5 includes a drive component 51 mounted on the camera 2 and connected to the side of the virtual display screen 3 away from the micro projector 4 for driving the micro projector 4 and the virtual display screen 3 to switch postures, and a trigger component 52 mounted on the drive component 51 for turning the micro projector 4 or the virtual display screen 3 on and off according to the posture switch; the drive component 51 includes a connector 511 mounted on the camera 2, a rotating shaft 513 that runs longitudinally through the connector 511 and is rotatably connected to the connector 511, a concave frame 512 mounted on the outside of the connector 511 and fixedly connected to both ends of the rotating shaft 513, a protective box 515 fixedly mounted on the connector 511 and located below the rotating shaft 513, and an angle motor 514 fixedly mounted inside the protective box 515 for driving the rotating shaft 513 to rotate. The rotating shaft 513 is rotatably connected to the protective box 515, and the angle motor 514 is connected to the output terminal of the processing chip.

[0024] It is worth noting that the protective box 515 is fixedly equipped with a button connected to the input terminal of the processing chip for starting the angle motor 514.

[0025] When the user needs to use the virtual display screen 3 for near-eye display, they press the button on the protective box 515. The button transmits a start signal to the processing chip, which outputs a control signal to the angle motor 514. The angle motor 514 is energized and rotates the shaft 513 relative to the connector 511 and the protective box 515. The shaft 513 then rotates the concave frame 512, the virtual display screen 3, and the micro projector 4 together to a horizontal position, making the virtual display screen 3 parallel to the user's eyes. At this time, the trigger component 52 detects this position and feeds back the position signal to the processing chip. The processing chip controls the virtual display screen 3 to turn on and the micro projector 4 to turn off. The virtual display screen 3 then directly presents the image information to the user's eyes. The device allows for close-up viewing. When the user needs to switch to using the mini projector 4 for external projection, pressing the button on the protective box 515 again triggers the processing chip to receive the signal and control the angle motor 514 to rotate the shaft 513 in the opposite direction. The concave frame 512, the virtual display screen 3, and the mini projector 4 rotate to a vertical position with the shaft 513, with the mini projector 4 facing the external projection area. At this time, the trigger component 52 detects the vertical position signal and transmits it to the processing chip. The processing chip controls the virtual display screen 3 to turn off and the mini projector 4 to turn on. The mini projector 4 projects the image onto the external wall or device surface, completing the display mode switching operation, thereby realizing the switching between the virtual display screen 3 and the mini projector 4.

[0026] Furthermore, the triggering component 52 includes proximity switches 521 and 524 fixedly connected to the connector 511 at positions corresponding to both ends of the rotating shaft 513; connecting plates 522 and 525 fixedly connected to both ends of the rotating shaft 513 and located on the same side; metal plates 523 and 526 fixedly connected to connecting plates 522 and 525 for sensing and cooperating with proximity switches 521 and 524 to activate the virtual display screen 3 and the micro projector 4; and two protective sleeves 527 fixedly connected to the concave frame 512 near the two ends of the rotating shaft 513 and respectively covering the outside of proximity switches 521 and 524. The end of the protective sleeve 527 away from the concave frame 512 is rotatably connected to the connector 511. Proximity switches 521 and 524 are vertically arranged, and both proximity switches 521 and 524 are connected to the input terminal of the processing chip.

[0027] When the angle motor 514 drives the rotating shaft 513 to rotate to a horizontal viewing position where the virtual display screen 3 faces the user's eyes, the rotating shaft 513 simultaneously drives the connecting plate 522 and the metal plate 523 to rotate to the sensing position corresponding to the proximity switch 521. The metal plate 523 and the proximity switch 521 form an effective sensing trigger. At the same time, the metal plate 526 and the proximity switch 524 move away from each other and release the sensing. The proximity switch 521 transmits the detected horizontal positioning signal to the processing chip in real time. After receiving the position signal, the processing chip performs logic processing and then controls the virtual display screen 3 to turn on and simultaneously turns off the micro projector 4, so that the device stably enters the near-eye display working mode for users to perform close-range, private information viewing operations. When the angle motor 514 drives the rotating shaft 513 to rotate to a vertical projection position where the micro projector 4 faces outwards, the rotating shaft 513 simultaneously drives the connecting plate 525 and the metal plate 526 to rotate to the sensing position corresponding to the proximity switch 524. According to the position, the second metal piece 526 and the second proximity switch 524 form an effective sensing trigger. At the same time, the first metal piece 523 and the first proximity switch 521 move away from each other and release the sensing. The second proximity switch 524 transmits the detected vertical position signal to the processing chip in real time. After receiving the position signal, the processing chip performs logic processing and then controls the virtual display screen 3 to turn off and the micro projector 4 to turn on simultaneously, so that the device can stably switch to the external projection display mode, so that the user can project information onto a distant wall or equipment surface for viewing and operation. Since the first proximity switch 521 and the second proximity switch 524 are arranged vertically, the two position detection signals can be independent and do not interfere with each other. Structurally, it avoids false triggering and false operation during the display mode switching process. At the same time, the protective cover 527 rotates synchronously with the concave frame 512 and always covers the outside of the first proximity switch 521 and the second proximity switch 524, which can provide continuous and effective dustproof, oilproof and physical collision protection for the two sets of proximity switches.

[0028] Furthermore, the focusing structure 6 includes a distance sensor 61 fixedly mounted on the lens side of the micro projector 4 for measuring the distance to the projection position, and a telescopic component 62 mounted on the camera 2 and connected to the connecting seat 511 for adjusting the projection distance of the micro projector 4. The distance sensor 61 is connected to the input terminal of the processing chip, and the telescopic component 62 is connected to the output terminal of the processing chip. The telescopic component 62 includes a fixed frame 621 fixedly connected to the side of the camera 2, an L-shaped frame 622 passing through the fixed frame 621 and slidably connected within the fixed frame 621, and an electric telescopic rod 623 fixedly mounted on the outside of the fixed frame 621 and connected to the output terminal of the processing chip. The telescopic end of the electric telescopic rod 623 is fixedly connected to the outside of the L-shaped frame 622 away from the fixed frame 621, and the end of the L-shaped frame 622 away from the fixed frame 621 is fixedly connected to the side of the connecting seat 511 away from the concave frame 512.

[0029] When the switching structure 5 rotates the micro projector 4 to a vertical projection position and the processing chip controls the micro projector 4 to turn on, the focusing structure 6 starts working simultaneously. The distance sensor 61 detects the distance between the lens of the micro projector 4 and the target surface in front, such as the wall or the surface of the device, in real time, and continuously transmits the detected distance data to the input of the processing chip. After receiving the distance signal, the processing chip performs logical calculations based on the preset clear projection distance parameters to determine whether the current projection distance is sufficient to achieve a clear image. If the distance is detected to be too far or too close, resulting in a blurry image, the processing chip immediately outputs a telescopic control command to the electric telescopic rod 623 of the telescopic component 62. After receiving the command, the electric telescopic rod 623 drives its telescopic end to telescopically extend and retract, thereby driving the L-shaped frame 622, which is fixedly connected to it, to slide linearly along the fixed frame 621. Since the L-shaped frame 622 is fixedly connected to the connecting seat 511, the L-shaped frame... The sliding of 622 synchronously drives the connecting base 511, the concave frame 512, and the micro projector 4 connected to the concave frame 512 to move back and forth as a whole, thereby changing the distance between the lens of the micro projector 4 and the projection target surface. During this process, the distance sensor 61 continuously detects the distance and feeds back the signal. The processing chip continuously adjusts the extension and retraction of the electric telescopic rod 623 according to the real-time feedback distance data until the distance between the micro projector 4 and the projection target surface reaches the preset clear projection distance. The processing chip stops outputting commands to the electric telescopic rod 623, and the electric telescopic rod 623 stops extending and retracting and maintains its current position. At this time, the image projected by the micro projector 4 reaches a clear state. Among them, the fixed frame 621 provides stable sliding support for the L-shaped frame 622, ensuring that the sliding process of the L-shaped frame 622 is smooth and without deviation, thereby ensuring the precise movement of the micro projector 4 and avoiding the projection image deviation or inaccurate focus due to movement deviation.

[0030] Example 2 Unlike Example 1, as Figure 7 As shown, in order to facilitate the adjustment of the distance between the virtual display screen and the eyes, a distance measuring sensor 31 for measuring the distance to the eyes is fixedly installed on the virtual display screen 3. The distance measuring sensor 31 is connected to the input terminal of the processing chip.

[0031] When the switching structure 5 rotates the virtual display screen 3 to a horizontal viewing position facing the user's eyes, the processing chip controls the virtual display screen 3 to turn on and the micro projector 4 to turn off. Distance sensor 1 61 then turns off, and distance sensor 2 31 simultaneously starts working, continuously performing non-contact detection of the distance between the virtual display screen 3 and the user's eyes. This allows for accurate acquisition of distance data without direct eye contact. Distance sensor 2 31 continuously transmits the real-time detected eye-screen distance signal to the input of the processing chip. Upon receiving this distance data, the processing chip combines it with preset near-eye comfortable viewing distance parameters to adapt to human eye viewing habits, avoiding visual fatigue from being too close and blurry images from being too far. It performs logical calculations and judgments to analyze whether the current eye-screen distance is within a comfortable and clear viewing range. If the processing chip determines that the current eye-screen distance is too close, it will trigger... The corresponding control logic triggers the telescopic component 62 of the focusing structure 6 to retract the electric telescopic rod 623, causing the L-shaped frame 622 to slide along the fixed frame 621. This, in turn, moves the virtual display screen 3 away from the eyes via the connecting seat 511 and the concave frame 512 until the eye-screen distance is adjusted to a preset comfortable range. When the processing chip determines that the current eye-screen distance is too far, it also triggers the telescopic component 62 to extend the electric telescopic rod 623, bringing the virtual display screen 3 closer to the eyes, thus completing the precise adjustment of the distance. When the detected eye-screen distance is within the preset comfortable range, the distance sensor 2 31 continuously feeds back a stable signal, and the processing chip does not trigger the telescopic component 62 to maintain the current position of the virtual display screen 3. This ensures that the user can comfortably view the information presented on the virtual display screen 3 for an extended period of time, further enhancing the ease of use and user-friendliness of the device.
