[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 This utility model provides a technical solution: a sensor switch based on holographic projection technology, comprising:

[0030] The outer shell 1 has an internal receiving chamber. A light-transmitting cover 2 is provided on its front side, and a terminal for connecting the power cord is provided on its back side. A control board 4, electrical components 5, and a mounting bracket 6 are installed inside. An imaging component 7 is installed on the mounting bracket 6. The imaging component 7 includes a molded light strip 9, an optical waveguide plate 8, and an image source.

[0031] Among them, the molded light strip 9 is located in front of the optical waveguide plate 8, the image source is located between the molded light strip 9 and the optical waveguide plate 8, the light rays of the image source incident on the image are emitted through the optical waveguide plate 8 to generate holographic imaging 3, and an infrared emitter 10 for detecting human hand movement information is installed inside the housing 1.

[0032] The optical waveguide plate 8 is installed inside the housing. The light rays of the incident image from the imaging component 7 pass through the optical waveguide plate 8 to generate a high-quality holographic image, which is then transmitted through the light-transmitting cover plate 2 to form a holographic image 3 corresponding to the incident image.

[0033] Specifically, the terminal connects to the power cord to provide power to the entire switch. Electrical component 5 supplies power to components such as the control board 4. Imaging component 7 generates incident image light, which, after passing through the optical waveguide plate 8, generates a high-quality holographic image. This image is then transmitted through the light-transmitting cover 2 to form a holographic image 3, which allows users to interact with the system. Through a unique structural design, holographic image 3 is achieved, eliminating the need for direct contact with the switch surface and solving the hygiene problem of existing smart switches. Furthermore, the form of holographic image 3, compared to traditional planar designs, adds a sense of technology and novelty, meeting users' demands for personalized experiences. The outer shell 1 provides overall protection and structural support, while the light-transmitting cover 2 protects the internal components and displays the holographic image. The mounting bracket 6 is used to install the imaging component 7 and the custom-molded light strip 9. All components work together to construct a complete holographic projection sensing switch system.

[0034] The control board 4 and electrical components 5 are installed inside the housing 1. The control board 4 is connected to the infrared transmitter 10 to receive data from the infrared transmitter 10 and generate control signals.

[0035] Specifically, the infrared transmitter 10 monitors the movement of objects such as human fingers in the surrounding environment in real time. When an object enters the sensing range, it transmits data to the control board 4. The control board 4 analyzes and processes the received data according to a preset algorithm to generate corresponding control signals. Utilizing infrared sensing enables contactless control, avoiding the accidental activation problems of hand-operated switches and improving the accuracy and reliability of control. It also solves the problem of existing switches being unfriendly to users with hand disabilities, making operation more convenient. Furthermore, in public places and other scenarios, contactless control further ensures hygiene and safety.

[0036] See Figure 4 Electrical component 5 provides power to control board 4, imaging assembly 7, molded light strip 9 and infrared transmitter 10.

[0037] Specifically, after the electrical component 5 is connected to the external power supply, it distributes electrical energy to the control board 4, imaging component 7, molded light strip 9, and infrared transmitter 10, ensuring that each component works normally and maintaining the stable operation of the entire switching system. Providing stable power supply to the entire system ensures the normal functioning of each component and is the foundation for the normal operation of the entire holographic projection-based induction switch. It guarantees the reliability and stability of the switch, enabling it to continuously and stably provide services to users.

[0038] See Figure 4 The pattern of the imaging component 7 can be adjusted as needed, and can be illuminated or extinguished under the control of the control panel 4.

[0039] Specifically, users can adjust the pattern of the imaging component 7 according to their own needs through specific settings such as mobile APP or cloud platform. The control board 4 controls the imaging component 7 to light up or turn off according to the user's operation instructions or preset program, thereby realizing the control of the displayed content. This meets the user's personalized needs. Users can customize the pattern of the imaging component 7 according to different scenarios, moods or usage habits, which greatly enhances the user's personalized experience. At the same time, the controllable light-up and turn-off function also helps to save energy. The imaging component 7 is turned off when it is not needed, which is in line with the concept of energy conservation and environmental protection.

[0040] See Figure 4 The light-transmitting cover plate 2, the light waveguide plate 8, the mounting bracket 6, and the control plate 4 are arranged sequentially from front to back along the long side of the outer shell 1.

[0041] Specifically, this layout allows the components to be arranged in an orderly manner inside the housing 1, ensuring that light emitted from the imaging component 7 can pass smoothly through the light-transmitting cover 2 after being refracted by the light waveguide plate 8 to form a clear holographic image 3. It also facilitates the wiring connection and signal transmission between the components, and the control board 4 can receive and process relevant signals in a timely manner. The reasonable layout design optimizes the internal structure of the entire switch, improves the space utilization, facilitates the collaborative work between the components, ensures the normal realization of holographic projection imaging and sensing control functions, and also facilitates the production, assembly and subsequent maintenance of the switch.

[0042] See Figure 4 The imaging component 7 and the holographic imaging 3 are axially symmetrical about the optical waveguide plate 8.

[0043] Specifically, the light emitted by the imaging component 7 is refracted by the optical waveguide plate 8 to form a clear and stable holographic image 3 at a specific position, allowing users to operate and interact from the optimal viewing angle. This ensures the stability and accuracy of the holographic image, enabling users to obtain a clear and intuitive operating interface, improving the convenience and interactive experience of user operation, and avoiding inconvenience caused by unstable imaging or positional deviation.

[0044] See Figure 4 The optical waveguide plate 8 is installed at an angle inside the housing 1, and the angle between the image source and the optical waveguide plate 8 is 25°~40°.

[0045] Specifically, the tilt angle of the optical waveguide plate 8 is adjusted according to the actual usage scenario and user needs, thereby changing the refraction path of light within the optical waveguide plate 8 and thus changing the angle of the holographic imaging 3 to adapt to different installation positions and user viewing habits. This enhances the adaptability of the switch, allowing users to flexibly adjust the imaging angle according to the actual situation. Whether installed at a high, low, or special location on the wall, it ensures that users can easily see and operate the holographic imaging 3, improving the practicality and applicability of the product.

[0046] See Figure 1 The light-transmitting cover 2 is made of transparent or semi-transparent glass material and has light-transmitting properties.

[0047] Specifically, this allows the holographic image light refracted by the waveguide plate 8 to pass through smoothly, forming a clear holographic image 3 on the cover surface for users to view and operate; it ensures the clear display of the holographic image, while the glass material has a certain degree of wear resistance and protection, protecting the internal imaging components 7, waveguide plate 8 and other components, without affecting the display effect of the holographic image, and extending the service life of the switch.

[0048] Working principle:

[0049] The switch is connected to the power cord through the terminal block on the back of the housing 1. The electrical component 5 distributes the power to the control board 4, the imaging component 7, the molded light strip 9 and the infrared emitter 10 to power the entire system. The mounting bracket 6 inside the housing 1 is used to support the imaging component 7 and the molded light strip 9. The components are arranged in an orderly manner inside the housing 1. The light-transmitting cover plate 2, the light waveguide plate 8, the mounting bracket 6 and the control board 4 are arranged in sequence from front to back along the long side of the housing 1 to ensure smooth light transmission and signal processing.

[0050] The image source in the imaging component 7 generates incident image light. The light is processed by the optical waveguide plate 8 and a holographic image is generated using its microchannel matrix technology. Since the imaging component 7 and the holographic image 3 are axially symmetrical about the axis of symmetry of the optical waveguide plate 8, the holographic image can be stably transmitted from the light-transmitting cover plate 2 to form a clear holographic image 3. Users can adjust the pattern of the imaging component 7 according to their needs. The control plate 4 can control its light emission or extinguishing. In addition, the angle of the holographic image 3 can be adjusted by changing the tilt angle of the optical waveguide plate 8 to change the light refraction path and thus adjust the angle of the holographic image 3 to adapt to different usage scenarios and user viewing habits.

[0051] Infrared transmitters 12 and receivers are arranged around the projection area to detect the user's finger movements in real time. The infrared transmitters 12 continuously emit infrared light. When there is no obstruction, the receiver receives the light signal and converts it into a stable electrical signal. When the user's finger blocks the infrared light, the receiver cannot receive the light and outputs a level transition signal. After processing, the signal is transmitted to the controller 4. The controller 4 analyzes the signal and outputs the corresponding control command to complete the switch opening and closing.

[0052] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
