The desktop telescopic image display device, through the telescopic image optical system, enlarges the image of the built-in display screen, and presents it in the form of a virtual image through the window 2 at a position not less than 3 meters in front of the human eye (preferably more than 5 meters). The user can see an enlarged virtual image of at least 3 meters away and at least 30 inches at the exit pupil position in front of the window 2, which enables the user to continue to see far during use.

[0035] The desktop telescopic image display device has a window 2 arranged on the front of the housing 1, and the window 2 is generally arranged at an angle; an opening 3 is arranged at the front of the housing 1, and the position of the opening 3 is not limited to a position lower than the window 2, but preferably a position lower than the window 2; a camera module 4 is arranged inside the housing 1 near the opening 3; preferably, the camera module 4 is arranged at a position lower than the window 2. When the housing 1 is an inclined surface at the position of the opening 3, and the light entrance hole of the image acquisition element of the camera module 4 is exposed to the opening 3, the image can be collected from the lower area between the opening 3 and the exit pupil position without changing the position of the camera module 4. In other cases, it is necessary to consider adjusting the position of the camera module 4 so that it can collect images from the lower area between the opening 3 and the exit pupil position and adapt to the user's usage habits. For this purpose, a position adjustment mechanism is introduced into the desktop telescopic image display device. The position adjustment mechanism is fixedly connected to the camera module 4, and can make the camera module 4 extend and / or rotate relative to the opening 3, so as to adjust the data acquisition area of ​​the camera module 4.

[0036] exist Figures 2 to 6 An implementation of the camera module 4 and its posture adjustment mechanism is given in the figure, wherein the camera module 4 includes a mounting seat 41, a camera and its accessory components 42 and a protective shell 43, and the posture adjustment mechanism includes a damping shaft 7 arranged on both sides of the protective shell 43; the camera and its accessory components 42 are fixedly connected to the mounting seat 41, and the mounting seat 41 covers the opening 3 before the posture of the camera and its accessory components 42 is changed; the camera and its accessory components 42 are arranged between the mounting seat 41 and the protective shell 42, and the mounting seat 41 and the protective shell 43 are fixedly connected, and the camera module 4 is rotationally connected to the outer shell 1 through the damping shaft 7, and the two ends of the damping shaft 7 are respectively fixed to the outer shell 1 and the protective shell 43, so that the protective shell 43 (as well as the mounting seat 41 and the camera and its accessory components 42) can rotate relative to the outer shell 1, thereby changing the posture of the camera module 4. Figure 2 As shown, during the rotation of the camera module 4, the light collecting element of the camera module (specifically, the light inlet 44) rotates from the opening 3 to the outside of the housing 1, and can collect data toward the lower front.

[0037] As a preferred implementation, a camera cover 8 is provided at a position corresponding to the opening 3 inside the shell 1. The camera cover 8 is fixedly connected to the shell 1 to close the opening 3 from the inside, and the camera cover 8 and the shell 1 have a space recessed inward from the opening 3 for accommodating the camera module 4; the camera cover 8 also has a limiting effect on the damping shaft 7, pressing the fixed side of the damping shaft 7 onto the shell 1.

[0038] exist Figures 7 to 10Another implementation of the camera module 4 and its posture adjustment mechanism is given in the figure. The posture adjustment mechanism includes a pop-up mechanism or a pull-out mechanism for changing the position of the camera module 4, and a limiting mechanism for fixing the camera module 4 to an initial state.

[0039] Specifically, the camera module 4 includes a drawer-type mounting seat 14, and the camera and its accessory components 15 are fixedly arranged inside the mounting seat 14. The posture adjustment mechanism includes a spring piece 16 arranged on the upper side of the drawer-type mounting seat 14, and a protrusion 17 is arranged on the upper surface of the spring piece 16 to form a limiting mechanism, and a pop-up mechanism is arranged on the rear side of the mounting seat 14. A groove 19 is arranged near the opening 3 of the outer shell 1 for limiting the protrusion 17. Pressing the spring piece 16, the protrusion 17 slides out of the groove 19, releasing the limiting effect of the outer shell 1, and the mounting seat 14 pops up, exposing the camera and its accessory components 15 arranged inside the mounting seat 14, pushing the mounting seat 14 inward, and the protrusion 17 is stuck in the groove 19, so that the camera module 4 is limited to the initial state inside the outer shell 1.

[0040] Figures 8 to 10 A specific implementation of the elastic mechanism is shown. The elastic mechanism includes a spring 24 and a pull wire 22, one end of the pull wire 22 is fixed to the mounting seat 14, the other end of the pull wire 22 is connected to one end of the spring 24, and the other end of the spring 24 is fixed to the housing 1 (through a fixing member 25). In order to adjust the direction of the pull wire 22, the pull wire 22 is passed through the gap between the housing 1 and the cover 18, and then bypasses the rotating shaft 23. In this embodiment, when the mounting seat 14 is pushed into and restricted in the opening 13, the spring 24 is in a stretched state, and when the spring sheet 16 is pressed to release the restriction, the mounting seat 14 is ejected from the opening 13 under the action of the spring 24.

[0041] In other embodiments not shown in the figures, the elastic mechanism may include only a spring. A camera cover is arranged at a position corresponding to the opening 13 on the inner side of the housing 1, and a spring is arranged between the camera cover and the camera module 4.

In the initial state, when the position of the camera module 4 is not adjusted, the camera module 4 covers the opening 3. By rotating the camera module 4 and adjusting the position of the camera module 4, the light inlet of the camera module 4 is exposed to the outside of the housing 1, thereby collecting images of the lower area between the opening 3 and the exit pupil position.

[0044] In this embodiment, and Figure 1 Similarly, an illumination module 10 is also provided in the housing 1. The illumination module 10 is preferably provided at the bottom of the housing 1 or at a position near the bottom of the lower side of the housing 1, and is used to illuminate the lower area between the opening 3 and the exit pupil position to achieve fill light. The illumination module 10 is preferably provided at a position lower than the camera module 4. A light baffle can also be provided on the front side of the illumination module 10, that is, between the illumination module 10 and the exit pupil position, to limit the light emitted forward by the illumination module 10 to prevent the light from directly entering the human eye. The light baffle is fixed to the housing 1, and the lower edge of the light baffle is lower than the lower edge of the illumination module 10. The light baffle can be provided vertically or tilted downward and forward.

[0045] In order to monitor the light intensity of the camera module image acquisition area and realize reasonable fill light, the desktop telescopic image display device also includes a light sensor 11, which is arranged at the lower part or bottom of the housing 1 and is used to collect the light intensity of the lower area between the opening 3 and the exit pupil position. The desktop telescopic image display device provides reasonable fill light suggestions or automatically adjusts the brightness of the lighting module according to the illumination monitoring result of the light sensor 11.

[0046] To sum up, the desktop telescopic image display device provided by the utility model sets the camera module inside the shell. When in use, it can be used directly or after changing the posture according to the specific setting method of the camera module. In this way, the camera module and its connecting wires are set inside the shell without being exposed, thereby avoiding accidental damage to the camera module and increasing the service life of the camera module.
