Description

Technical Field

[0001] The utility model relates to the technical field of projection, in particular to a human body induction interactive projection in an exhibition hall. Background Art

[0002] The human body sensing interactive projection in the exhibition hall is a display system that combines human body sensing technology and interactive projection technology. It can realize the interaction between users and projected images by sensing the movements and positions of the human body. The human body sensing interactive projection system in the exhibition hall has rich interactive functions. Users can interact with the projected images through gestures, touch or body movements. For example, users can control the zooming in, zooming out, rotating, etc. of the image through gestures, and can also select, drag, click and other operations by touching the screen.

[0003] Such a projection device is usually equipped with sensors and cameras for sensing the user's interactive behavior. These sensors and cameras can identify the user's gestures, touch positions or handwriting, and transmit this information to the system for processing. In the prior art, the human body sensing interactive projection device in the exhibition hall is equipped with cooling devices such as cooling fans. These cooling devices are started when the projection device is started, and the inside of the projection device is continuously cooled. The driving of devices such as cooling fans requires additional large amounts of energy, which increases the energy consumption of the device. Secondly, when there is no user interaction, components such as cameras and sensors inside the projection device are not in working condition. At this time, the overall heat dissipated inside the projection device is low, and the continuous operation of the cooling device causes excessive energy consumption, resulting in poor thermal energy management of the device.

[0004] Therefore, it is necessary to design a human body sensing interactive projection in the exhibition hall to solve the above problems. Utility Model Content

Both the air storage pipe and the main pipe are provided with two one-way valves, and the limiting directions of the two one-way valves are opposite. A valve is provided on the air storage pipe, and a push rod is fixed on the sliding plug, one end of the push rod extends to the outside of the sleeve toward the direction of the air storage pipe, an inclined block 1 and an inclined block 2 are fixed on the push rod, and the rotating rod handle of the valve is located between the inclined block 1 and the inclined block 2, the air storage pipe is connected to the interior of the projection device, and the air storage pipe and the heat dissipation pipe are respectively located at two ends inside the projection device.

[0013] The utility model has the following beneficial effects:

[0014] 1.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Embodiment 1

[0025] Reference Figure 1-5, a human body sensing interactive projection in an exhibition hall, comprising an interactive table 1 with a hollow interior, an interactive board 2 fixedly connected to the interactive table 1, a bracket 3 fixed to the interactive board 2, a projection device 4 installed at the bottom of the bracket 3, the interactive board 2 is used to display the projection image of the projection device 4, and is also an operation platform for users to interact, a plurality of heat dissipation holes 5 are arranged on both side walls of the projection device 4, a mesh cover directly facing the heat dissipation holes 5 is arranged on the projection device 4, and plays a dustproof role, a heat dissipation component for dissipating heat from the projection device 4 is arranged inside the interactive table 1, the heat dissipation component comprises a sleeve 6 fixedly connected to the interior of the interactive table 1, a sliding plug 7 is sealed and slidably connected inside the sleeve 6, a heat dissipation pipe 8 and a main pipe 14 are connected on the sleeve 6, and the main pipe 14 and the heat dissipation pipe 8 are respectively located on both sides of the sliding plug 7, the heat dissipation pipe 8 is connected with the interior of the projection device 4, and the heat dissipation component also comprises a plurality of driving parts;

[0026] The driving member includes an elastic sheet 10 fixedly connected to the upper surface of the interactive table 1, and the connection between the elastic sheet 10 and the interactive table 1 is in a sealed state. A branch pipe 11 and an air inlet pipe 12 are connected between the interactive table 1 and the elastic sheet 10. The air inlet pipe 12 is connected to the inside of the interactive table 1, and the branch pipe 11 is connected to the main pipe 14. A one-way valve 13 is provided on the branch pipe 11 and the air inlet pipe 12, and the flow limiting directions of the two one-way valves 13 are opposite. Under the action of the one-way valve 13, the outside air can only enter between the elastic sheet 10 and the interactive table 1 through the air inlet pipe 12, and the air between the two can only be discharged through the branch pipe 11. The elastic sheet 10 is made of rubber, which reduces the cost, and the elastic sheet 10 made of rubber can be deformed at various positions on its surface, which will not cause safety hazards to the user's walking. The elastic sheet 10 is provided with anti-slip grooves, which increase the friction between the elastic sheet 10 and the user's soles, and improve the overall safety of the device. The inner top surface of the interactive table 1 is provided with a plurality of dustproof nets, and the dustproof nets are directly opposite to the air inlet pipe 12. Under the effect of dustproof, dust and other impurities in the air entering between the elastic sheet 10 and the interactive table 1 can be filtered out, so that the air entering the projection device 4 will not cause damage to the components in the device.

[0027] Working principle: the projection device 4 will project an image onto the interactive board 2. When the user performs an interactive action, the sensor and camera inside the projection device 4 are in operation. The user will walk on the interactive table 1. When the user steps on the elastic sheet 10, the elastic sheet 10 will be squeezed downward, and the elastic sheet 10 will be deformed and the air inside will enter the main pipe 14 through the branch pipe 11, and then enter the sleeve 6. At this time, the space between the sliding plug 7 and the main pipe 14 is inflated, and the sliding plug 7 will move, thereby squeezing the air between the sliding plug 7 and the heat pipe 8 into the projection device 4, so as to achieve heat dissipation of the projection device 4. The deformed elastic sheet 10 will pass the outside air through the air intake pipe under the action of its own elastic force. 12 is sucked in and restored, so that every time the user walks, the projection device 4 will be cooled once. Such a setting does not need to use additional energy to drive the operation of cooling devices such as cooling fans. While cooling the device, it also reduces the use cost of the projection device 4. When there is no user interaction, the device is in a low-heat state, and there is no need to drive the cooling device to cool the projection device 4, which reduces the energy consumption of the device. It is worth mentioning that during the working hours of the exhibition hall, the user continuously steps on the elastic sheet 10 to fill the sleeve 6 with air, which is adapted to the capacity of the sleeve 6. This can reduce the number of maintenance times for the device by the staff and ensure the normal operation of the cooling component.

[0028] Embodiment 2

[0029] Embodiment 2 includes the contents of Embodiment 1, and the technical features disclosed in Embodiment 1 are also applicable to this embodiment. The technical features disclosed in Embodiment 1 will not be described repeatedly. The implementation method of human body sensing interactive projection in the exhibition hall will be further described in detail below in conjunction with the accompanying drawings.

[0030] Reference Figure 2-5, the interior of the sleeve 6 is also provided with an air storage component, the air storage component includes a spring 9 arranged between the sleeve 6 and the sliding plug 7, the sleeve 6 is also connected with an air storage pipe 15, and the air storage pipe 15 and the main pipe 14 are located on the same side of the sliding plug 7, the air storage pipe 15 and the main pipe 14 are both provided with a one-way valve 16, and the limiting directions of the two one-way valves 16 are opposite. Under the action of the one-way valve 16, the outside air can only enter the sleeve 6 through the main pipe 14, and the air in the sleeve 6 can only enter the projection device 4 through the air storage pipe 15. A valve 17 is provided on the air storage pipe 15, and the structure of the valve 17 includes a cock, a rotary rod and a rotary rod handle. The rotation of the rotary rod can control the rotation of the cock, thereby controlling the closing and opening of the valve 17. The rotary rod handle is fixed to the rotary rod and is located outside the air storage pipe 15. This structure is a prior art and will not be described in detail here. A push rod 18 is fixed on the sliding plug 7, and one end of the push rod 18 faces the direction of the air storage pipe 15 The push rod 18 extends to the outside of the sleeve 6, and an inclined block 19 and an inclined block 20 are fixed on the push rod 18, and the rotating rod handle of the valve 17 is located between the inclined block 19 and the inclined block 20, and the inclined surfaces of the inclined block 19 and the inclined block 20 are both facing the valve 17, and the distance between the inclined block 19 and the inclined block 20 is adapted to the moving distance of the sliding plug 7. The gas storage pipe 15 is connected with the inside of the projection device 4, and the gas storage pipe 15 and the heat dissipation pipe 8 are respectively located at two ends inside the projection device 4. The heat dissipation pipe 8 and the gas storage pipe 15 are both made of aluminum material to ensure the heat dissipation performance of the pipeline. When the sliding plug 7 moves in a direction away from the heat dissipation pipe 8, the hot air in the projection device 4 will be sucked into the heat dissipation pipe 8. During the flow process, under the heat dissipation performance of the aluminum material, the heat in the air in the heat dissipation pipe 8 will be dissipated, so that when the sliding plug 7 moves in a direction close to the heat dissipation pipe 8, the heat in the air entering the projection device 4 will be lower than the heat inside the projection device 4.

[0031] Working principle: when the user steps on the elastic sheet 10, the sliding plug 7 will be driven to move and the projection device 4 will dissipate heat. Different from the first embodiment, the capacity of the sleeve 6 becomes smaller. During the interaction process, each time the user steps on the elastic sheet 10, the sliding plug 7 and the push rod 18 will be pushed to one side once, and the device will be cooled once. The movement of the push rod 18 will drive the inclined block 19 to move in the direction close to the valve 17. At the same time, the air between the sliding plug 7 and the main pipe 14 will increase to realize the air storage operation. In the process of the sliding plug 7 moving to the extreme position, the push rod 18 drives the inclined block 19 to move. Under the action of the inclined surface of the inclined block 19, the inclined block 19 will squeeze the rotating rod handle of the valve 17 to make it rotate, so that the valve 17 is in an open state. Under the elastic force of the spring 9, the air between the sliding plug 7 and the main pipe 14 will be quickly squeezed into the air storage pipe 15, and then the air enters the projection device 4 to realize The heat dissipation effect on the components is achieved, and in this process, the movement of the sliding plug 7 will also suck the hot air in the projection device 4 into the sleeve 6 through the heat dissipation pipe 8, so that the hot air can be sucked away while blowing the outside air into the projection device 4, which improves the heat dissipation efficiency and ensures the heat dissipation effect. On the contrary, when the air between the sliding plug 7 and the main pipe 14 is completely squeezed into the projection device 4, that is, when the sliding plug 7 and the push rod 18 are reset, the inclined block 20 will be driven to move toward the direction of the valve 17. Under the action of the inclined surface of the inclined block 20, the inclined block 20 will squeeze the rotating rod handle on the valve 17 to reverse and reset it, thereby closing the valve 17. At this time, the user's stepping will cause the device to enter a new round of air storage process. The sensors and cameras in the projection device 4 will emit a large amount of heat during long-term interactive operations. This air storage design can quickly and effectively dissipate heat for the device to ensure the performance of the device.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
