[0029] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. used in the present invention to indicate the orientation or positional relationship are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices and elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] In the description of this utility model, it should be understood that the terms "first," "second," etc. are used to describe various types of information, but such information should not be limited to these terms. These terms are merely used to distinguish information of the same type from one another. For example, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information without departing from the scope of this utility model.

[0032] In related technologies, while telescopic display devices provide myopia prevention and control functions, they are often limited by their fixed or limited adjustment capabilities and cannot flexibly adjust the display angle and position according to the user's needs, which affects the user's visual comfort and reduces the effectiveness of myopia prevention and control.

[0033] like Figure 1As shown, an embodiment of the present invention provides a telescopic image display device, which includes an optical module 10 and a driving assembly 20. The optical module 10 is used to reflect an image from a near position to a far position; the driving assembly 20 includes a first driving mechanism 21, a screw body 22 and a moving block 23. The moving block 23 is provided with an internal threaded hole, and the screw body 22 is arranged in a vertical direction and penetrates the internal threaded hole; the optical module 10 is rotatably connected to the moving block 23, and the optical module 10 can be flipped around the moving block 23 in a vertical plane; the first driving mechanism 21 is used to drive the screw body 22 to rotate, so that the moving block 23 moves along the axial direction of the screw body 22 with the optical module 10.

[0034] In this embodiment, the optical module 10 reflects the image from a near position to a far position, simulating the effect of long-distance viewing, thereby reducing the burden on the user's eyes and preventing myopia. The optical module 10 integrates precise optical components to ensure the clarity and accuracy of image transmission.

[0035] The drive assembly 20 includes a first drive mechanism 21, a screw body 22 and a moving block 23, wherein the first drive mechanism 21 can be used as a power source, and the rotational motion of the motor is converted into the rotational motion of the screw body 22 through a transmission mechanism (such as a gear set, a pulley, etc.). The first drive mechanism 21 can receive an external control signal and adjust the rotation speed and direction of the screw body 22 according to the instruction. The screw body 22 is arranged in a vertical direction, and its surface is processed with a spiral groove. The moving block 23 is internally provided with an internal threaded hole that matches the spiral groove of the screw body 22, and is connected to the linear motion of the screw body 22 by threaded matching. The moving block 23 is also provided with a rotating connection structure (such as a rotating shaft, a hinge, etc.) that is compatible with the optical module 10, so that the optical module 10 can perform a flipping motion around it.

[0036] Based on the above technical solution, when the display position of the telescopic display device needs to be adjusted, the first drive mechanism 21 is activated to drive the screw body 22 to rotate. The helical groove and the internally threaded hole cooperate to cause the movable block 23 to move the optical module 10 up and down along the axial direction of the screw body 22 to adjust the display position. As the movable block 23 moves up and down, due to the rotational connection between the optical module 10 and the movable block 23, the user can manually or automatically flip the optical module 10 in a vertical plane about the rotation center of the movable block 23, thereby adjusting the angle of the optical module and, consequently, the display angle, to meet viewing needs.

[0037] Therefore, the telescopic image display device of this embodiment, through the design of the drive assembly 20, successfully solves the technical problem of the existing technology that the display angle and position cannot be flexibly adjusted. Users can freely adjust the display position and angle of the telescopic image display device according to factors such as their own vision, viewing habits, and ambient light conditions to obtain the best visual experience and myopia prevention and control effect. The telescopic image display device has a compact structure and is easy to operate, and has a high application prospect.

[0038] In actual application, the moving block 23 carries the optical module 10 and moves along the screw body 22 to adjust the display position. However, if the movement range of the moving block 23 is not restricted, the optical module 10 may exceed its normal operating range, even causing equipment damage or safety hazards.

[0039] In one embodiment, drive assemblies 20 are provided on both sides of the optical module 10. Specifically, the left side of the optical module 10 includes a first drive mechanism 21, a screw body 22, and a moving block 23, while the right side of the optical module 10 also includes a first drive mechanism 21, a screw body 22, and a moving block 23. These two drive assemblies 20 control the left and right sides of the optical module 10, respectively, achieving synchronous drive on both sides and improving the stability and reliability of the optical module 10 during movement and flipping.

[0040] As an embodiment, the telescopic display device includes a first limit sensor 30 and a second limit sensor 40, which are spaced apart along the screw body 22, and are used to limit the moving block 23.

[0041] Specifically, a first limit sensor 30 is positioned axially along the screw body 22 at a preset starting limit point, limiting the minimum upward movement limit of the movable block 23. A second limit sensor 40 is also positioned axially along the screw body 22, but on the opposite side from the first limit sensor 30, limiting the maximum downward movement limit of the movable block 23. When the movable block 23 moves upward as the screw body 22 rotates and approaches the first limit sensor 30, the first limit sensor 30 detects the position of the movable block 23 and transmits a signal to the control system. Upon receiving the signal, the control system immediately stops the operation of the first drive mechanism 21, thereby preventing the movable block 23 from further upward movement and achieving the position limit. Similar to the first limit sensor 30, when the movable block 23 moves toward the second limit sensor 40, the second limit sensor 40 detects its position and transmits a signal to the control system. Upon receiving the signal, the control system also stops the operation of the first drive mechanism 21, limiting further movement of the movable block 23.

[0042] As an embodiment, the moving block 23 includes a block body 231 and a rotating shaft 232 . The internal threaded hole is provided in the block body 231 . The rotating shaft 232 is fixedly connected to the block body 231 . The optical module 10 is rotatably connected to the rotating shaft 232 .

[0043] Specifically, the block body 231 is the primary component of the moving block. It features an internally threaded hole that engages the spiral groove of the screw body 22 to achieve linear motion. A rotational shaft 232 is fixedly connected to the block body 231 and serves as the rotational support point for the optical module 10. The optical module 10 is rotationally connected to the rotational shaft 232 via a rotational connection mechanism.

[0044] In a telescopic display device, the rotational connection between the optical module 10 and the moving block 23 is crucial for achieving adjustment of the display angle. However, if the rotational connection is too flexible or lacks proper damping, the adjustment may be unstable or difficult to precisely control.

[0045] As an embodiment, the moving block 23 further includes a damping ring 233 . The damping ring 233 is sleeved on the rotating shaft 232 , and the damping ring 233 is disposed between the optical module 10 and the block body 231 .

[0046] Specifically, the damping ring 233 is made of an elastic material (such as rubber, silicone, etc.), and the damping ring 233 can be set to a shape that fits tightly with the rotating shaft 232 to ensure that it can be stably fixed on the rotating shaft 232. When the optical module 10 flips around the rotating shaft 232, the damping ring 233 will be subjected to the extrusion force and friction force from the optical module 10. Due to the elastic characteristics of the damping ring 233, it will provide a certain resistance to slow down the flipping speed of the optical module 10, thereby achieving the effect of damping adjustment. After the optical module 10 completes the flipping, the damping ring 233 can keep the optical module 10 at the current angle position. Therefore, this embodiment is more stable and precise when adjusting the display angle by setting the damping ring 233. The damping ring 233 can reduce the vibration and noise caused by too fast or unstable operation, thereby improving the operating experience.

[0047] As an embodiment, the telescopic display device also includes a fixed bracket 50, which is provided with an opening 51 for accommodating the optical module 10, and the optical module 10 can be flipped around the movable block 23 in the opening 51; the fixed bracket 50 is provided with a sliding groove 52 extending along the axial direction of the screw body 22, and when the first driving mechanism 21 drives the screw body 22 to rotate, the movable block 23 moves in the sliding groove 52 along the axial direction of the screw body 22.

[0048] Specifically, the fixed bracket 50 serves as the supporting structure of the entire telescopic display device. It is provided with an opening 51 for accommodating the optical module 10. The size and shape of the opening 51 match the optical module 10. The optical module 10 is stably installed in the fixed bracket 50 and can be flipped and adjusted within a certain range.

[0049] The fixing bracket 50 is further provided with a sliding groove 52 extending axially along the screw body 22 . The width and depth of the sliding groove 52 are designed according to the size of the moving block 23 to ensure that the moving block 23 can move axially along the screw body 22 in the sliding groove 52 .

[0050] In operation, the screw body 22 is driven to rotate forward or reverse by controlling the start and stop of the first drive mechanism 21, thereby driving the movable block 23 to move within the sliding groove 52. Furthermore, because the optical module 10 and the movable block 23 are rotationally connected via the rotating shaft 232 and the damping ring 233, the optical module 10 can be tilted and adjusted around the movable block 23 within the opening 51. This complex adjustment method allows the user to freely adjust the display angle as needed to obtain the optimal visual effect.

[0051] As an embodiment, the fixed bracket 50 is composed of an inner bracket 501 and an outer bracket 502. The inner bracket 501 is sleeved inside the outer bracket 502. The inner bracket 501 serves as the main load-bearing part of the fixed bracket and is provided with structural features that match the optical module 10 and the moving block 23, such as the precise size of the opening 51, the guide groove corresponding to the sliding groove 52, etc. The inner bracket 501 is made of high-strength material and can withstand the weight of the optical module 10. The inner bracket 501 is sleeved inside the outer bracket 502, and the two are fixed together by fasteners (such as screws, snaps, etc.), thereby enhancing the overall strength of the fixed bracket 50. The outer bracket 502 serves as a protective layer and auxiliary support part of the inner bracket 501. It is provided with a size and shape that matches the inner bracket 501. The outer bracket 502 is wrapped around the outside of the inner bracket 501, and the two are tightly assembled and combined to form a whole.

[0052] As an embodiment, the fixed bracket 50 includes a base 53 and side panels 54 connected to both sides of the base 53. The two side panels 54 and the base 53 enclose an opening 51. The side panels 54 are provided with a sliding groove 52 and a cavity for installing the screw body 22. The first driving mechanism 21 is arranged inside the base 53.

[0053] Specifically, the base 53 is located at the bottom of the fixed bracket 50, providing support for the entire device. The first drive mechanism 21 is located within the base 53 and is connected to the screw body 22 via a transmission mechanism to achieve its driving function. The side panel 54 defines a cavity for mounting the screw body 22 (the cavity formed by the assembly of the inner bracket 501 and the outer bracket 502).

[0054] As an embodiment, the optical module 10 includes a housing 11 and an optical element 12. The housing 11 includes a cover 111 and a flip cover 112. The optical element 12 is disposed inside the cover 111. The optical element 12 is used to reflect an image from a near position to a far position. The cover 111 is provided with an exit port 113 for emitting light. The flip cover 112 covers the exit port 113 and is rotatably connected to the top of the cover 111.

[0055] Specifically, the housing 11 serves as a protective structure, housing and securing an optical element 12 within it. The optical element 12 is responsible for reflecting images from a near position to a distant position. The housing 11 comprises a cover 111 and a flip cover 112. The cover 111 serves as the main body, and its interior space is used to mount and secure the optical element 12. The cover 111 also has an exit port 113 for emitting light. Light reflected from the optical element 12 is transmitted through the exit port 113 to a target location. The flip cover 112, a reversible component, is equipped with a rotating connection structure (such as a hinge or a rotating shaft) that matches the top of the housing 111, allowing the flip cover 112 to open and close around the rotational connection point. When closed, the flip cover 112 tightly seals the exit port 113, protecting the optical element 12 within from external factors such as dust and moisture. To adjust the light emission direction or perform other operations, the flip cover 112 is opened to the desired angle.

[0056] As an embodiment, the optical module 10 includes a second driving mechanism 13 . The second driving mechanism 13 is disposed inside the housing 111 and is configured to drive the flip cover 112 to flip relative to the top of the housing 111 .

[0057] Specifically, the second drive mechanism 13 is fixed to the inside of the cover 111 by means of screws, snaps, etc., and the second drive mechanism 13 is connected to the flip cover 112 through a mechanical transmission device (such as a transmission gear, etc.). When the second drive mechanism 13 receives a control signal, it drives the flip cover 112 to flip relative to the top of the cover 111, thereby opening the flip cover 112 and exposing the outlet 113.

[0058] As an embodiment, the first driving mechanism 21 and / or the second driving mechanism 13 is a driving motor.

[0059] Specifically, the first drive mechanism 21, serving as the power source for controlling the movement or adjustment of the optical module 10, can employ a stepper motor, servo motor, or DC motor. Because the opening and closing of the flip cover 112 is relatively simple and requires slightly less control precision than the movement and adjustment of the optical module, the second drive mechanism 13 can utilize a more cost-effective motor type, such as a DC motor or a micro-stepping motor. Both the drive motors in the first drive mechanism 21 and the second drive mechanism 13 are controlled by a control system. Based on instructions or pre-set programs, the control system sends control signals to the drive motors, enabling functions such as starting, stopping, forward and reverse rotation, and speed regulation.

[0060] As an embodiment, a counterweight 55 is provided inside the base 53 .

[0061] Specifically, the material of the counterweight 55 has a high density and is not easily deformed or damaged. Common counterweight materials include metals (such as iron, lead, etc.) and high-density plastics. The counterweight 55 can be a cube, a rectangular parallelepiped, or a specially shaped counterweight, and can be installed in the groove or gap within the base 53. This embodiment, by increasing the weight of the base 53 and rationally distributing the counterweight 55, can improve the anti-tilting capability and overall stability of the telescopic display device.

[0062] As an embodiment, a first control button 60, a second control button 70 and a switch button 80 are provided on the fixed bracket 50. The first control button 60 is used to control the operation of the first driving mechanism 21 so that the moving block 23 moves upward along the screw body 22. The second control button 70 is used for the first driving mechanism 21 to work in reverse so that the moving block 23 moves downward along the screw body 22. The switch button 80 is used to control the power on and off of the optical module 10.

[0063] As an embodiment, the optical module 10 includes a display screen, a curved screen and semi-transparent and semi-reflective glass (not shown in the drawings). Among them, the display screen is the core display component in the optical module 10, which can present images and video content. The display screen can adopt a variety of technologies such as LCD, OLED, Mini LED, etc. to achieve display effects such as high resolution, high color saturation and wide viewing angle. The curved screen has a wider viewing angle range, which adds a three-dimensional sense to the display screen. The semi-transparent and semi-reflective glass transmits and reflects light to a certain extent, so that the user can see the image on the display screen and the surrounding environment at the same time. Of course, the optical module 10 may also include other components, which are not specifically limited in this embodiment.
