Description

Technical Field

[0001] This invention belongs to the field of outdoor electronic equipment technology, specifically relating to a platform for intelligent interactive popular science knowledge. Background Technology

[0002] The intelligent interactive platform is an intelligent interactive all-in-one machine developed to meet people's needs for interactive communication. Currently, popular science knowledge is widely displayed in electronic energy-saving exhibition halls, specifically in the form of text, sound, graphics, images, animation, etc.

[0003] In public places such as campuses, community centers, and shopping malls, especially in open-air public spaces, the use of interactive platforms for popular science knowledge faces significant limitations. Due to factors such as temperature and weather in the outdoor environment, the lifespan of the interactive platform can be greatly affected. Therefore, existing interactive platforms need to be placed in real time according to environmental changes when used outdoors. For example, in rainy or snowy weather, the existing interactive platforms may be affected during data interaction. To address this, we propose an intelligent interactive platform for popular science knowledge. Summary of the Invention

[0004] The purpose of this invention is to provide a platform for intelligent interactive popular science knowledge, in order to solve the problems mentioned in the background art.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A platform for intelligent interaction of popular science knowledge includes a lower housing and an upper housing. The upper housing has four sides, each of which is equipped with a touch screen. The top of the upper housing has a recess, and a lens antenna for wireless transmission of popular science knowledge data is horizontally arranged at the bottom of the recess. The sides of the lower housing have a connector for wired transmission of popular science knowledge data. The inner sides of the recess are sloped, facing the lens antenna, and are equipped with metal springs for reflecting the electromagnetic wave signals of the lens antenna.

[0007] A further improvement is that a gas chamber and an air pump are provided inside the recess at the lower end of the metal spring sheet. A piston chamber is connected to the concave surface of the gas chamber facing the metal spring sheet. A piston is movably installed in the piston chamber. A connecting plate is fixedly connected to the concave surface of the metal spring sheet. A connecting pipe is provided on the end face of the gas chamber away from the air pump.

[0008] A further improvement is that the plug-in end includes an outer shell and a sealing plate that seals the outer shell. Both ends of the sealing plate are vertically provided with positioning rods. The front of the outer shell is provided with a positioning cavity that cooperates with the positioning rods to position the sealing plate. The lower end of the positioning cavity is provided with a gas interface, which is connected to the connecting pipe.

[0009] A further improvement is that the lens antenna includes a reflector mount and a lens located within the reflector mount, and an annular airbag communicating with the connecting pipe is embedded on the reflector mount and above the lens.

[0010] A further improvement is that drainage holes are provided at the bottom of the recess and on the upper housing.

[0011] The beneficial effects of this invention are as follows:

[0012] In this invention, the interactive platform can switch between wireless and wired transmission by starting the air pump to inflate or deflate the air. The overall solution is simple and practical. While switching the transmission mode, it can also effectively protect the other transmission end. Therefore, the interactive platform can be used in various outdoor environments for popular science education.

[0013] In this invention, the interactive platform can switch the data transmission mode of popular science knowledge through an air pump, and at the same time, the air pump can adjust the curvature of the outer metal spring of the lens antenna to achieve multi-angle reception of wireless data. Compared with the prior art, which frequently adjusts the pitch angle of the lens antenna to change the radiation angle of the feed, the gain effect is more obvious, and the service life of the lens antenna is longer.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above-described contents.

[0021] Example 1

[0022] like Figure 1-4 As shown, this embodiment proposes a platform for intelligent interaction of popular science knowledge. It is characterized by comprising a lower housing 1 and an upper housing 2. The upper housing 2 has four sides, each with a touch screen 3 embedded therein. A recess 4 is provided at the top of the upper housing 2, and a lens antenna 5 for wireless transmission of popular science data is horizontally arranged at the bottom of the recess 4. A plug-in terminal 6 for wired transmission of popular science data is provided on the side of the lower housing 1. The inner perimeter of the recess 4 is sloped, facing the lens antenna 5, and a metal spring 10 for reflecting the electromagnetic wave signal of the lens antenna 5 is provided.

[0023] In this embodiment, the interactive platform displays science education information and a virtual learning environment through a touch screen in an outdoor setting, creating a rich and engaging learning atmosphere. The touch screen also enables human-computer interaction. To further facilitate signal reception during science education interaction, a lens antenna is used. Lens antennas can expand communication signal coverage, improve signal quality and capacity, and offer advantages in cost and weight, making them more suitable for mobile communication, IoT, and other applications. Therefore, in outdoor mobile scenarios, the use of a lens antenna provides a more stable signal reception capability for the interactive platform.

[0024] In addition, by providing a wired transmission connector 6 in the lower housing 1, the present invention makes the interactive platform applicable to a wider range of scenarios. For example, in areas with signal shielding or unstable wireless signals, maintenance personnel can transmit popular science data via wired connection through connector 6 on-site, thus not affecting the use of the interactive platform in that area.

[0025] Connector 6 is a data transmission port for wired transmission, including but not limited to USB interface, HDMI interface, SDI interface, VGA interface, DVI interface, AV interface, etc.

[0026] In this embodiment, combined with Figure 2 The arc of the metal spring 10 is dynamically adjustable, which enables real-time reception of popular science signal data from multiple angles. Compared with the existing technology that frequently adjusts the pitch angle of the lens antenna to change the radiation angle of the feed, the gain effect is more obvious, and the service life of the lens antenna is longer.

[0027] Combination Figure 2 and 3 A gas chamber 7 and an air pump 8 are provided inside the recessed part 4 at the lower end of the metal spring 10. A piston chamber 11 is connected to the concave surface of the gas chamber 7 facing the concave surface of the metal spring 10. A piston is movably provided in the piston chamber 11. A connecting plate 12 is fixedly connected to the concave surface of the metal spring 10. A connecting pipe 9 is provided on the end face of the gas chamber 7 away from the air pump 8.

[0028] Preferably, the plug-in end 6 includes an outer shell 61 and a sealing plate that seals the outer shell 61. Both ends of the sealing plate are provided with vertical positioning rods 62. The front of the outer shell 61 is provided with a positioning cavity 63 that works with the positioning rods 62 to position the sealing plate. The lower end of the positioning cavity 63 is provided with a gas interface 64, which is connected to the connecting pipe 9.

[0029] Preferably, the lens antenna 5 includes a reflector 51 and a lens located within the reflector 51, and an annular airbag 52 connected to the connecting tube 9 is embedded on the reflector 51 and above the lens.

[0030] In this embodiment, by providing an air pump 8 and a gas chamber 7 inside the recess 4, when wired data transmission is required through the plug-in terminal 6, the air pressure of the annular airbag 52 connected through the connecting pipe 9 will gradually increase when the air pump is started to inflate the gas chamber 7. The annular airbag 52 will then inflate and expand, thus protecting the lens antenna 5. In other words, when using wired transmission, the lens antenna 5 can be covered and wrapped by the annular airbag 52.

[0031] In addition, when the annular airbag 52 is fully inflated, the metal fragment 10 will be at its maximum curvature.

[0032] In this embodiment, when the air pump 8 is started to inflate the gas chamber 7, and gas is introduced into the lower end of the positioning cavity 63 of the gas interface 64 connected to the connecting pipe 9 during inflation, the positioning rod 62 will disengage from the positioning cavity 63, thereby opening the insertion interface between the sealing plate and the outer shell 61, enabling wired data transmission of the terminal 6.

[0033] When the air pump 8 is activated to evacuate the gas chamber 7, the positioning chamber 63 and the piston chamber are in a negative pressure state, which causes the annular airbag 52 to contract. The lens antenna 5 can receive and transmit signals normally. When the positioning chamber 63 is in a negative pressure state, the positioning rod 62 can be positioned in the positioning chamber 63 under the action of negative pressure, which can effectively protect the plug end 6.

[0034] It should be noted that when the air pump 38 is pumping air, the piston can drive the connecting plate 12 to adjust the curvature of the metal spring 10, so as to adjust the maximum gain angle of the lens antenna.

[0035] Preferably, both the bottom of the recess 4 and the upper shell 2 are provided with drainage holes 13 for collecting rainwater in the recess 4 in outdoor scenarios.

[0036] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
