Description

Technical Field

[0001] This utility model relates to the field of projection equipment, specifically a wall projection interactive device based on a laser sensor. Background Technology

[0002] A laser sensor-based wall projection interactive device is an interactive system that combines laser sensors, projection technology, and computer processing. It can realize touch, gesture recognition, and interactive projection functions on the wall. It emits an invisible laser light screen through a laser radar or laser emitter to detect the user's gestures or actions. The projector projects computer-generated images onto the wall to form an interactive display area. The user action data captured by the laser sensor is transmitted to the computer through a protocol (such as TUIO), and the computer processes it to generate interactive effects.

[0003] Interactive projection devices are typically placed in high-traffic areas of exhibition halls. Visitors often bring drinks such as milk tea. When using these devices, users usually place the drinks on the device's surface and interact by gesturing to the screen. However, due to the large crowds and the physical movements of users, the drinks can easily be spilled, contaminating the device and affecting subsequent users. Therefore, this paper proposes a wall-mounted interactive projection device based on a laser sensor to address these issues. Utility Model Content

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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a wall projection interactive device based on a laser sensor, including a projection interactive device 1. A fixed compartment 2 is fixedly disposed on the side of the housing of the projection interactive device 1. An arc-shaped toothed drive component 5 is disposed on the frame of the fixed compartment 2. A movable compartment 3 is fixedly connected to the rod of the arc-shaped toothed drive component 5. A cover compartment 4 is disposed on the upper part of the movable compartment 3. A plurality of retractable components 6 are disposed on the bottom of the fixed compartment 2. A handle 8 is disposed on the end of the arc-shaped toothed drive component 5.

[0025] The fixed compartment 2 includes: a connecting handle 21 and a hinge rod 22. The side of the fixed compartment 2 is fixedly connected to the end of the connecting handle 21. The connecting handle 21 is fixedly connected to the threaded hole of the projection interaction device 1 by bolts. The frame of the fixed compartment 2 is rotatably connected to one end of the hinge rod 22, and the other end of the hinge rod 22 is rotatably connected to the frame of the cover compartment 4.

[0026] The mobile compartment 3 includes: a support plate 31 and a second hinge rod 32. The inner frame of the mobile compartment 3 is fixedly connected to the plate body of the support plate 31. The frame of the mobile compartment 3 is rotatably connected to one end of the second hinge rod 32, and the other end of the second hinge rod 32 is rotatably connected to the frame of the cover compartment 4.

[0027] The arc-shaped tooth drive component 5 includes: a second connecting column 50, a linkage rod 51, and a power rod 52. The tooth end of the arc-shaped tooth drive component 5 is fixedly connected to the curved part of the linkage rod 51. The column of the tooth of the arc-shaped tooth drive component 5 is rotatably connected to the frame of the fixed compartment 2. One end of the linkage rod 51 is fixedly connected to one end of the second connecting column 50. The other end of the second connecting column 50 is fixedly connected to one end of the power rod 52. The other end of the power rod 52 is rotatably connected to the end of the handle 8. The other end of the linkage rod 51 is connected to the frame of the movable compartment 3.

[0028] The linkage rod 51 also includes a connecting column 511. One end of the linkage rod 51 is fixedly connected to one end of the connecting column 511, and the other end of the connecting column 511 is rotatably connected to the frame of the mobile compartment 3.

[0029] The shrinkable component 6 includes a spring 61 and a sliding column 62. The inner wall of the shrinkable component 6 is slidably connected to the column of the sliding column 62. One end of the sliding column 62 is fixedly connected to one end of the spring 61, and the other end of the spring 61 is fixedly connected to the inner wall of the shrinkable component 6.

[0030] Working principle: When the user uses the projection interactive device 1, they first grasp the handle 8 and push it downwards. The handle 8 drives the power rod 52 downwards, and the connection between the power rod 52 and the connecting column 50 rotates downwards. This causes the two teeth of the arc-shaped tooth drive 5 to rotate, which in turn causes the linkage rod 51 to move the moving chamber 3 to both sides. The meshing of the two teeth ensures that the opening of the moving chamber 3 is stable and does not wobble. As the moving chamber 3 moves, the hinge rod 32 pushes the cover chamber 4 to unfold as well. The hinge rod 22 ensures that the unfolding of the cover chamber 4 is stable and does not wobble. At this point, the user can choose whether to place their water cup on the support plate 31 or in the fixed chamber 2, depending on the shape of their cup. If the bottom of the cup can be placed stably, then... If the bottom of the cup bulges or has irregular protrusions, it can be placed in the fixed compartment 2. As the cup with an irregular bottom is placed on the retractable part 6, some of the sliding columns 62 will retract into the retractable part 6 due to the contact and pressure of the cup. The other sliding columns 62 that are not retracted into the retractable part 6 will provide all-round support for the side of the cup, preventing the cup from tipping over. After the cup is placed, pull the handle 8 upward, causing the connection between the power rod 52 and the connecting column 2 50 to move upward, causing the connection between the linkage rod 51 and the connecting column 2 50 to rotate upward, thereby completing the closure of the moving compartment 3 and the cover compartment 4. This will block the placed cup and prevent surrounding dust from falling onto the cup.

[0031] The multi-layered design of the fixed compartment 2 and the movable compartment 3 allows for the placement of water cups or other containers in different situations, and can accommodate multiple people's cups at the same time. After placement, the cover compartment 4 can be sealed to prevent dust raised by people from falling on the cups. The double-tooth engagement of the arc-shaped tooth drive component 5 makes the opening of the movable compartment 3 more stable, while the engagement of the first hinge rod 22 and the second hinge rod 32 makes the movement of the cover compartment 4 stable. Moreover, this operation method is simple and easy for tourists to use.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
