[0031] The following description is intended to disclose the present disclosure so that those skilled in the art can implement the present disclosure. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art may readily conceive of other obvious variations. The basic principles of the present disclosure defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present disclosure.

[0032] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0033] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0034] In this disclosure, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections, or communication; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0035] In related art, the screen of a welcome machine is typically positioned outward, allowing users to directly observe the displayed content and easily touch the screen for touch operations. However, this outward-facing display makes the screen susceptible to damage, resulting in a shorter display lifespan. Furthermore, the user's touch easily leaves bacteria and viruses on the screen, which can be picked up by the next user, increasing the chance of their spread and posing a health risk.

[0036] In view of this, the present disclosure provides a medium-free holographic welcome machine, the screen of the medium-free holographic welcome machine display is difficult to damage, the display has a long service life, and is conducive to the user's subsequent contactless operation of the display content, which is conducive to protecting the user's health.

[0037] Figure 1 It is a structural diagram of the medium-free holographic welcoming machine according to an embodiment of the present disclosure. Figure 2 It is a side view schematic diagram of the medium-free holographic welcoming machine according to an embodiment of the present disclosure. Figure 3 yes Figure 2 The horizontal cross-sectional view of the medium-free holographic reception machine on the AA section line. Figures 1 to 3 The medium-free holographic welcoming machine of the embodiment of the present disclosure includes a shell 10, a display 20 and an imaging plate 30.

[0038] Optionally, the housing 10 includes an annular wall 11, a front sidewall 13, and a rear sidewall 12. The front sidewall 13 and the rear sidewall 12 are respectively fixedly connected to the annular wall 11. The bottom of the annular wall 11 is fixedly connected to a self-supporting base 40. The annular wall 11, the front sidewall 13, and the rear sidewall 12 enclose a closed cavity 101. The annular sidewall 11 is vertically arranged and has a rounded rectangular shape. The display 20 is vertically fixed to the first inner wall of the annular sidewall 11. The front sidewall 13 has the transmissive area 102 at the front opening away from the rear sidewall 12. In addition to being configured as a rounded rectangular shape, the annular sidewall 11 can also be configured as a vertical cross-section with an elliptical or oblong shape, or other shapes. The specific shape can be adjusted according to actual needs.

[0039] In other examples, the annular sidewall 11 includes an upwardly protruding arcuate top wall 111 , a downwardly protruding arcuate bottom wall 112 , and two middle straight walls 113 connected between the arcuate top wall 111 and the arcuate bottom wall 112 .

[0040] It is understandable that the cavity 101 formed in the housing 10 having the above shape has a larger volume and a larger height, which facilitates the installation of other components, such as the display 20 and the imaging board 30 .

[0041] Optionally, the transmission area 102 may be formed at the first side opening of the annular side wall 11, for example Figure 3 The transmissive area 102 may also be a light-transmitting member disposed at the front opening of the annular sidewall 11. Thus, light within the cavity 101 of the housing 10 can be transmitted to the exterior of the housing 10 through the transmissive area 102. The light-transmitting member may be a transparent glass plate or a non-transparent, light-transmitting glass / plastic / resin lens, as long as it can achieve light transmission.

[0042] The display 20 is disposed in the cavity 101 to emit imaging light for forming a screen image.

[0043] Optionally, the display 20 is vertically mounted on a sidewall adjacent to the sidewall where the transmissive area 102 is located. Furthermore, since the display 20 is disposed within the cavity 101, the screen 21 of the display 20 is also located within the cavity 101. Thus, the housing 10 can provide a certain degree of protection for the screen 21 of the display 20.

[0044] In addition, it is worth mentioning that the rounded corners of the shell 10 can focus the light emitted by the display 20, so that the light emitted by the display 20 can be fully gathered and subsequently transmitted through the transmission area 102, thereby ensuring that the corresponding image formed by the transmitted light is clearer and the display effect is better.

[0045] Optionally, the display 20 may be a screen for displaying a welcome message. The welcome message can serve as a guide for reception and can be adaptively changed according to different application scenarios of the medium-free holographic welcome machine. Thus, when the display is in use, it illuminates and displays, thereby forming a screen image containing the welcome message.

[0046] The imaging plate 30 is disposed between the display 20 and the transmission area 102 to guide the screen image to form a floating image 900 . The floating image 900 is located outside the transmission area 102 and away from the housing 10 .

[0047] Optionally, the imaging plate 30 is a light waveguide plate, which can receive the imaging light emitted by the display 20, refract the imaging light through the transmission area 102 to the outside of the transmission area 102, and transmit the imaging light to a predetermined position through the light-transmitting element of the transmission area 102, thereby forming a floating image 900 outside the transmission area 102.

[0048] In other words, the imaging light emitted by the display 20 passes through the transmissive area 102 via the imaging plate 30 and forms a floating image 900 in the area outside the transmissive area 102. Specifically, the floating image 900 is arranged symmetrically with the display 40, with the imaging plate 30 as the axis of symmetry. Furthermore, during the above process, since the display 20 is located within the cavity 101 and the screen 21 of the display 20 is also located within the housing 10, the housing 10 provides a certain degree of protection for the screen 21 of the display 20. Therefore, the screen 21 of the display 20 of the media-free holographic reception machine disclosed herein is less susceptible to external corrosion, extending its service life. Furthermore, since the screen image of the display 20 of the present invention is formed in the air outside the media-free holographic reception machine, the user can subsequently adjust the floating image 900 by performing corresponding control operations on the floating image 900 in conjunction with the operation recognition component. This allows the user to manipulate the displayed content of the display 20 without touching the transmissive area 102, preventing cross-infection in public environments and protecting the user's health.

[0049] It's also worth noting that when a perspective mirror is provided in the transmissive area 102, it's preferably a one-way mirror. This mirror can transmit light from within the housing 10 to the exterior, but prevents light from outside the housing 10 from passing through it. This shields the internal structure of the housing 10, enhancing the overall aesthetics of the media-free holographic reception machine. Furthermore, when the floating image 900 is being imaged, the mirror can appear black behind it, effectively illuminating the floating image 900 and enhancing its visual quality.

[0050] Optionally, the operation recognition component may include an infrared sensor, which may be directly mounted on the media-free holographic reception machine or externally mounted on the media-free holographic reception machine for use with the media-free holographic reception machine. The infrared sensor's sensing window covers the floating image 900 and forms a sensing coordinate matrix in the area of ​​the floating image 900. When the user performs an aerial point control on the floating image 900, the infrared rays of the sensing coordinate matrix are reflected and received by the infrared sensor. The infrared sensor then processes the information to obtain the click position and combines the back-end information with the user's touch interface, thereby controlling the media-free holographic reception machine to perform corresponding actions according to the user's touch instructions.

[0051] Preferably, the one-way mirror is formed into an oblong shape. Specifically, the one-way mirror can be an elliptical one-way mirror, or a one-way mirror formed by connecting curved plates at both ends with a straight plate in the middle. The one-way mirror of the above structure has a large area and a wider coverage area, allowing more light to pass through, thereby making the floating image 900 clearer and more complete.

[0052] Figure 4 FIG is a schematic diagram of the arrangement of the imaging plate 30, the display 20 and the transmission area 201 according to an embodiment of the present disclosure. Figure 3 and Figure 4 The imaging plate 30 is positioned vertically at a predetermined angle relative to the screen 21 of the display 20. Specifically, the predetermined angle is preferably between 25 and 45 degrees, such as between 25 and 30 degrees, between 30 and 35 degrees, between 35 and 40 degrees, or between 40 and 45 degrees. More preferably, the imaging plate 30 is positioned at a 35-degree angle relative to the screen 21 of the display 20. In this case, the floating screen image guided by the optical waveguide plate is displayed with improved effect.

[0053] In addition, the floating image 900 and the screen image formed by the optical waveguide plate are symmetrically arranged with respect to the optical waveguide plate. By adjusting the relative angle between the screen 21 of the display 20 and the optical waveguide plate, the relative angle between the plane where the floating image 900 is located and the plane where the transmission area 102 is located can be adjusted, thereby facilitating the adjustment of the relative angle between the screen 21 of the display 20 and the optical waveguide plate to meet the different observation needs of different users.

[0054] like Figure 3 As shown, when the relative angle between the optical waveguide plate and the screen 21 of the display 20 is 45 degrees, the plane of the floating image 900 is arranged parallel to the plane of the transmissive area 102. In this case, when the medium-free holographic welcome machine is in use, a user standing facing the transmissive area 102 can fully observe the welcome information displayed by the floating image 900.

[0055] In other examples, when the relative angle between the optical waveguide plate and the screen 21 of the display 20 is 35 degrees, the plane of the floating image 900 is tilted left-right relative to the plane of the transmissive area 102. In this case, when the medium-free holographic welcome machine is in use, a user standing to one side of the transmissive area 102 in the left-right direction can clearly see the welcome information displayed by the floating image 900.

[0056] It should be noted that a redundant area 103 is provided between the screen 20 and the imaging plate 30. On the one hand, the redundant area 103 is used to adapt to various installation environments and can adjust the installation position. On the other hand, it can provide light redundancy, allowing more light to be effectively refracted by the imaging plate 30, thereby making the floating image 900 clearer and more complete.

[0057] Optionally, see Figure 1 The medium-free holographic welcoming machine further includes a self-propelled base 40. The self-propelled base 40 is arranged below the housing 10 in a movable manner.

[0058] Therefore, the self-propelled base 40 can carry the shell 10 and the above-mentioned display 20, imaging board 30 and other components installed on the shell 10, and when the self-propelled base 40 moves, the self-propelled base 40 can enable the medium-free holographic welcome machine to have a walking function, thereby facilitating the user to use the medium-free holographic welcome machine. For example, the medium-free holographic welcome machine can walk in front of the user according to the user's instructions to lead the user to the designated location, or the medium-free holographic welcome machine can walk to a position close to the user according to the user's instructions for the user to operate and use.

[0059] Specifically, a rolling wheel 41 is provided at the bottom of the self-propelled base 40. When the wheel 41 rolls on the ground, the self-propelled base 40 walks on the ground. The friction between the wheel 41 and the ground is small, the wear on the ground is small, and the noise is small.

[0060] Preferably, a accommodating recess 42 that is adapted to the shape of the bottom of the shell 10 and is recessed downward is formed on the top of the self-supporting base 40 , and the shell 10 is disposed in the accommodating recess 42 .

[0061] For example, when the bottom wall of the housing 10 is a downwardly convex arc-shaped bottom wall 112 , the accommodating recess may be configured as a downwardly concave arc-shaped recess that matches the shape of the arc-shaped bottom wall 112 .

[0062] Therefore, since the accommodating recess 42 can accommodate the bottom of the shell 10 and is adapted to the shape of the bottom of the shell 10, the shell 10 and the self-propelled base 40 are firmly installed and have high connection strength. During the walking process of the self-propelled base 40, the shell 10 and the self-propelled base 40 can move in unison without detaching.

[0063] Figure 5 yes Figure 1 An enlarged diagram of part A in Figure 2. Figure 1 and Figure 5 The medium-free holographic welcoming machine further includes an environment detection component 50. The environment detection component 50 is arranged on the self-propelled base 40 to detect the surrounding environmental characteristics.

[0064] Specifically, the environment detection component 50 is a combination of one or more cameras, photoelectric detectors, and laser radars. For example, the environment detection component 50 can be one or more cameras, one or more photoelectric detectors, one or more laser radars, or a combination of at least two or three of the above components.

[0065] Thus, the environment detection component 50 can provide corresponding environment monitoring data for the movement of the self-propelled base 40 , such as detecting whether there are obstacles around, etc., so as to facilitate the smooth movement of the self-propelled base 40 .

[0066] Optionally, the self-propelled base 40 is formed with a light-collecting recess 43 , and a sidewall of the light-collecting recess 43 is formed with a light-collecting slope 4301 facing the external environment. The environment detection component 50 is disposed at the light-collecting recess 43 and is located on the light reflection path of the light-collecting slope 4301 .

[0067] Therefore, when the environmental detection element 50 detects the environmental characteristics around the self-propelled base 40 by collecting the light around the self-propelled base 40, the light located around the self-propelled base 49 and irradiated on the focusing slope 4301 can be reflected to the environmental detection component 50, so that the environmental detection component 50 can more comprehensively receive the external light around the self-propelled base 40, and further enable the environmental detection component 50 to more comprehensively detect the surrounding environmental characteristics.

[0068] Those skilled in the art will appreciate that the embodiments of the present disclosure described above and shown in the accompanying drawings are provided for illustrative purposes only and do not limit the present disclosure. The advantages of the present disclosure have been fully and effectively realized.
