Description

Technical Field

[0001] This utility model relates to the field of interactive projection technology, specifically a product display device based on interactive projection. Background Technology

[0002] In today's commercial displays and product promotion fields, interactive projection technology, with its unique interactive experience and vivid display effects, has become an important means to attract consumer attention and enhance product display effectiveness. Interactive projection-based product display devices can present product information to the audience in a dynamic and three-dimensional way, and enhance the audience's sense of participation and understanding of the product through interactive elements. As market competition intensifies, the requirements for the functionality, stability, and aesthetics of product display devices are also increasing, prompting continuous improvement and innovation in related technologies.

[0003] Existing interactive projection-based product display devices mainly consist of a projection device, an electric telescopic frame, motion capture equipment (usually an infrared camera or a depth camera), a control host, a display platform, and a projection screen (or display wall, floor, etc.). The projection device is responsible for projecting pre-made product-related images onto the display area. The electric telescopic frame is used to adjust the height of the projection device. The motion capture equipment captures the audience's movements and gestures and transmits this information to the control host. After analyzing and processing the captured information, the control host adjusts the projection content in real time to achieve interactive effects between the audience and the projected image. During the display, the projection lens is responsible for projecting a clear image, while the motion capture lens is responsible for accurately capturing interactive movements. The two work together to complete the interactive product display function.

[0004] Existing product display devices typically expose their projection lenses and motion capture lenses directly to the air. When not in use, prolonged exposure to the air makes them highly susceptible to dust accumulation. This dust buildup on the lens surface can impair light transmittance, reduce the clarity, color vibrancy, and contrast of the projected image, resulting in blurry and dim product images that fail to accurately convey product details and advantages, severely impacting usability. Therefore, there is an urgent need to develop an interactive projection-based product display device that can automatically shield the lens when not in use, reducing dust interference. Summary of the Invention

[0005] Therefore, the purpose of this utility model is to provide a product display device based on interactive projection to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a product display device based on interactive projection, comprising an electric telescopic frame and a display device body, wherein a protective frame for protecting and storing the display device body is installed on the outer wall of the electric telescopic frame, and a protective plate is rotatably installed on the display device body for shielding the interconnected projection lens group set on the outer wall of the display device body.

[0007] The protective frame is equipped with a pull plate mechanism for driving the protective plate to unfold, and the protective frame is equipped with a reset mechanism for closing the protective plate.

[0008] The pull plate mechanism includes a take-up roller rotatably installed inside the protective frame and a pull rope installed on the take-up roller, as well as a spring installed inside the protective frame and corresponding to the take-up roller. The end of the pull rope is connected to the outer wall of the protective plate. The reset mechanism includes a limit wheel and a reset wheel for guiding the protective plate to rotate and reset. When the display device body enters the protective frame, the protective plate automatically resets under the guidance of the limit wheel and the reset wheel to protect the interconnected projection lens group.

[0009] By adopting the above technical solution, the plate pulling mechanism drives the protective plate to unfold through the take-up roller, pull rope and spring, and the reset mechanism guides the protective plate to close through the limit wheel and reset wheel. With the help of the electric telescopic frame lifting, it can cover the lens to prevent dust when idle and unfold for display. No manual operation is required, which improves convenience.

[0010] Furthermore, the protective frame is not connected to the telescopic outer wall of the electric telescopic frame, and the bottom of the protective frame is designed with an opening, which is larger than the display device body.

[0011] By adopting the above technical solution, the bottom opening of the protective frame is larger than the display device body, which facilitates its entry and exit, provides reliable storage space for the device, and reduces interference from the external environment.

[0012] Furthermore, two sets of extension plates are symmetrically installed at both the upper and lower ends of the display device body, and the width of the extension plates is greater than the width of the display device body and is slidably connected to the inner wall of the protective frame.

[0013] By adopting the above technical solution, the stability of the display device body within the protective frame is limited.

[0014] Furthermore, a bottom protective plate is installed on the bottom of the extension plate at the bottom of the display device body. The width and length of the bottom protective plate are both greater than the bottom opening of the protective frame and less than the width and length of the bottom of the protective frame. A sealing gasket is provided on the end face of the bottom protective plate.

[0015] By adopting the above technical solution, dust can be prevented from entering through the bottom opening during storage, reducing the risk of dust accumulation on the lens, while also buffering the impact of collisions during storage.

[0016] Furthermore, two sets of take-up rollers are symmetrically installed inside the protective frame. Both sets of take-up rollers are located between the outer extension plates and are offset from the setting position of the outer extension plates. The ends of the pull ropes on the take-up rollers are rotatably connected to the outer wall of the protective plate.

[0017] By adopting the above technical solution, both frictional interference with the outer plate is prevented, and the force is evenly distributed when the protective plate is pulled, ensuring smooth unfolding and repositioning.

[0018] Furthermore, the length of the pull rope is greater than the length of the electric telescopic frame that can be extended or retracted.

[0019] By adopting the above technical solution, the movement of the protective plate is ensured to be unrestricted by its lifting stroke.

[0020] Furthermore, both the limiting wheel and the reset wheel are rotatably mounted on the protective frame, and the installation positions of the limiting wheel and the reset wheel are offset from the setting positions of the take-up roller and the extension plate. In addition, multiple limiting wheels are installed at equal intervals on the inner wall of the protective frame, and the outer walls of multiple limiting wheels are all in contact with each other.

[0021] By adopting the above technical solution, the limiting wheels are installed at equal intervals and are attached to the protective plate, and the reset wheel assists in contact guidance. Both of them avoid the take-up roller and the outer plate, guiding the protective plate to close and align without interference, ensuring accurate blocking.

[0022] Furthermore, the reset wheel is rotatably mounted on the bottom of the outer wall of the protective frame, and the bottom ends of the reset wheel and the bottom set of limit wheels both protrude from the bottom of the protective frame. The top surface of the bottom guard plate is provided with a storage groove corresponding to the bottom set of limit wheels.

[0023] By adopting the above technical solution, it is ensured that the setting of the limit wheel will not affect the fit between the bottom guard plate and the protective frame.

[0024] Furthermore, a limiting block is installed on the top of the display device body to limit the tilt angle of the protective plate, and the outer wall of the limiting block is designed with an inclined surface and is attached to the outer wall of the protective plate after rotation.

[0025] By adopting the above technical solution, the rotation angle is precisely limited, avoiding damage to the protective plate due to excessive rotation and collision, and ensuring the normal operation of the display function.

[0026] In summary, the present invention has the following main advantages:

[0027] This utility model uses an electric telescopic frame to lift and lower the display device body. Combined with a pull plate mechanism and a reset mechanism, it realizes the automatic opening and closing of the protective plate. During display, the protective plate unfolds to ensure the normal operation of the interactive projection lens group. When not in use, the protective plate closes to block the lens. With the help of the protective frame for storage and the bottom protective plate for sealing, dust adhesion is greatly reduced. The extension plate enhances sliding stability, and the limit wheel and reset wheel guide the protective plate to accurately reset. The limit block restricts the rotation angle. The overall design takes into account both display effect and equipment protection, reduces maintenance frequency, and is suitable for long-term use in high-position installation scenarios.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] A product display device based on interactive projection, such as Figure 1 - Figure 6 As shown, it includes an electric telescopic frame 1 and a display device body 2;

[0038] Among them, the electric telescopic frame 1 provides lifting power for the display device body 2. The display device body 2 is used to realize interactive projection display of products. Its outer wall is equipped with an interactive projection lens group 21, which is used to project dynamic images and capture audience interaction actions. The outer wall of the electric telescopic frame 1 is equipped with a protective frame 3, which is used to protect and store the display device body 2. A protective plate 4 is rotatably installed on the display device body 2, which is used to cover the interactive projection lens group 21 to prevent it from accumulating dust when not in use.

[0039] In this embodiment, a pull plate mechanism is provided inside the protective frame 3; the pull plate mechanism is used to drive the protective plate 4 to unfold so that the interactive projection lens group 21 can work.

[0040] Meanwhile, a reset mechanism is provided on the protective frame 3. The reset mechanism is used to guide the protective plate 4 to close and protect the interactive projection lens group 21.

[0041] Specifically, the pull plate mechanism includes a take-up roller 6, a pull rope 7, and a spring.

[0042] The take-up roller 6 is rotatably installed inside the protective frame 3, the pull rope 7 is installed on the take-up roller 6 and its end is connected to the outer wall of the protective plate 4, and the spring is installed inside the protective frame 3 and corresponds to the take-up roller 6 to provide the return power for the take-up roller 6.

[0043] The reset mechanism includes a limiting wheel 9 and a reset wheel 10. When the display device body 2 enters the protective frame 3, the protective plate 4 automatically resets under the guidance of the limiting wheel 9 and the reset wheel 10, blocking the interactive projection lens group 21.

[0044] In this embodiment, the protective frame 3 is connected to the outer wall of the electric telescopic frame 1 without telescopic movement. The bottom of the protective frame 3 is designed with an opening, and the bottom opening is larger than the display device body 2, which facilitates the display device body 2 to enter and exit the protective frame 3. Two sets of outer extension plates 22 are symmetrically installed at both the upper and lower ends of the display device body 2. The width of the outer extension plate 22 is larger than the width of the display device body 2 and it is slidably connected to the inner wall of the protective frame 3 to enhance the stability of the display device body 2 after it enters the protective frame 3 and prevent it from shaking.

[0045] In this embodiment, the bottom of the extension plate 22 at the bottom of the display device body 2 is equipped with a bottom protective plate 5. The width and length of the bottom protective plate 5 are both greater than the bottom opening of the protective frame 3 and less than the width and length of the bottom of the protective frame 3. Its end face is provided with a sealing gasket. When the display device body 2 is stored in the protective frame 3, the bottom protective plate 5 is in contact with the bottom of the protective frame 3 to reduce the entry of dust.

[0046] In this embodiment, two sets of take-up rollers 6 are symmetrically installed inside the protective frame 3. Both sets of take-up rollers 6 are located between the outer extension plates 22 and are offset from the setting position of the outer extension plates 22 to avoid interference with the outer extension plates 22. The ends of the pull ropes 7 are rotatably connected to the outer wall of the protective plate 4 to ensure that the pull ropes 7 can smoothly pull the protective plate 4. The length of the pull ropes 7 is greater than the length of the electric telescopic frame 1 that can be extended and retracted, ensuring that the pull ropes 7 have sufficient slack during the lifting and lowering of the display device body 2. The connection position between the pull ropes 7 and the protective plate 4 is located above the interactive projection lens group 21 and below the rotatable connection position between the protective plate 4 and the display device body 2 to ensure that the protective plate 4 can be smoothly unfolded when pulled.

[0047] In this embodiment, both the limiting wheel 9 and the reset wheel 10 are rotatably mounted on the protective frame 3, and their installation positions are offset from the setting positions of the take-up roller 6 and the extension plate 22 to avoid interference; multiple limiting wheels 9 are installed at equal intervals on the inner wall of the protective frame 3, and the outer walls of multiple limiting wheels 9 are all in contact with the outer wall of the protective plate 4, which is used to guide the closing of the protective plate 4 and continuously restrict the protective plate 4;

[0048] The reset wheel 10 is rotatably installed at the bottom of the outer wall of the protective frame 3, and the bottom ends of the reset wheel 10 and the bottom set of limit wheels 9 both protrude from the bottom of the protective frame 3. At the same time, a storage groove 51 corresponding to the bottom set of limit wheels 9 is opened on the top surface of the bottom protective plate 5, so that the limit wheels 9 can be embedded when the display device body 2 is completely stored, ensuring that the bottom protective plate 5 and the protective frame 3 fit tightly.

[0049] In this embodiment, a limiting block 8 is installed on the top of the display device body 2. The outer wall of the limiting block 8 is designed with a slope and is attached to the outer wall of the rotated protective plate 4 to limit the tilt angle of the protective plate 4 and prevent it from rotating excessively.

[0050] Through the coordinated operation of the above components, during the display, the electric telescopic frame 1 extends, causing the display device body 2 to extend out of the protective frame 3, the pull plate mechanism drives the protective plate 4 to unfold, and the interactive projection lens group 21 works; after the display ends, the electric telescopic frame 1 retracts, causing the display device body 2 to retract into the protective frame 3, and the reset mechanism guides the protective plate 4 to close and block the lens, realizing the automatic switching between protection and display, reducing the impact of dust and reducing the maintenance frequency.

[0051] The specific working principle is as follows:

[0052] When product interactive projection display is required, the electric telescopic frame 1 starts and extends, driving the display device body 2 to extend downward from inside the protective frame 3; during the extension of the display device body 2, the pull plate mechanism starts simultaneously.

[0053] Specifically, when the display device body 2 slides downward, the protective plate 4 is restricted by multiple limiting wheels 9 and cannot change its angle. As the protective plate 4 slides downward with the display device body 2, it pulls the pull rope 7, which in turn causes the take-up roller 6 to start rotating. At this time, the spring starts to store energy. When the display device body 2 slides out of the protective frame 3, the protective plate 4 will separate from the limiting wheels 9 and lose the restriction of the limiting wheels 9. At this time, the take-up roller 6 will rotate under the elastic force of the spring and start to pull the pull rope 7 upward, so that the pull rope 7 pulls the protective plate 4 to rotate outward around its rotation axis with the display device body 2.

[0054] When the protective plate 4 rotates to be in contact with the inclined surface of the outer wall of the limiting block 8, the tilt angle of the protective plate 4 is limited to prevent it from rotating excessively. After unfolding, the protective plate 4 no longer blocks the interactive projection lens group 21, ensuring that the interactive projection lens group 21 can project images normally. If the position of the display device body 2 is not adjusted to a suitable position and still needs to be lowered, the protective plate 4 will pull the rope 7 again to ensure that the display device body 2 can continue to descend.

[0055] Meanwhile, the outer extension plates 22 at the upper and lower ends of the display device body 2 are slidably connected to the inner wall of the protective frame 3 to ensure that the display device body 2 is stable and does not shake during the extension process; the take-up roller 6 is located between the two sets of outer extension plates 22 and is staggered to avoid interference with the outer extension plates 22.

[0056] After the display ends, the electric telescopic frame 1 retracts, causing the display device body 2 to move upward and gradually return to the protective frame 3. During this process, the spring will gradually drive the take-up roller 6 to retract the pull rope 7 as the display device body 2 rises, preventing the pull rope 7 from interfering with other components.

[0057] During the retraction of the main body 2 of the display device, the reset mechanism works in coordination.

[0058] Specifically, as the display device body 2 moves upward, the outer wall of the protective plate 4 contacts the reset wheel 10 on the outer wall of the protective frame 3. At this time, the reset wheel 10 will stop the protective plate 4, so that the protective plate 4 will start to rotate in the opposite direction as the display device body 2 moves upward. When the display device body 2 begins to enter the protective frame 3, the protective plate 4 will contact the limiting wheel 9. As the end of the display device body 2 enters the protective frame 3, the protective plate 4 will be in contact with the outer wall of the display device body 2 under the restriction of the limiting wheel 9, and will cover the interactive projection lens group 21 to form physical protection, so as to prevent external dust from adhering to the interactive projection lens group 21 when not in use.

[0059] When the display device body 2 is fully inserted into the protective frame 3, the bottom protective plate 5 and the sealing gasket on its end face are in contact with the bottom of the protective frame 3, further reducing the possibility of dust entering from the bottom opening of the protective frame 3.

[0060] By closing the protective plate 4 and storing it with the protective frame 3, the contact area between the interactive projection lens group 21 and the air when it is idle is reduced, thereby reducing the rate at which dust accumulates on the lens surface.

[0061] Since the devices are usually installed in high positions such as exhibition hall ceilings and high walls, each cleaning or maintenance requires the use of climbing tools, which is inconvenient and inefficient. However, this device can effectively reduce the impact of dust on the interactive projection lens group 21 by automatically closing the protective plate 4 and retracting the display device body 2 into the protective frame 3 when idle, which significantly reduces the frequency of lens cleaning and equipment maintenance and solves the problem of inconvenient cleaning of high-position devices.

[0062] Although this device can reduce the impact of dust, a small amount of dust may still enter after long-term use. At this time, the main body 2 of the display device can be extended through the electric telescopic frame 1 to clean the interactive projection lens group 21 without having to climb up frequently.

[0063] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
