[0040] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0041] The invention relates to the field of interactive experiential science popularization education intelligent interactive exhibition halls, and provides a dynamic display device for geographical science popularization, which can automatically and dynamically demonstrate the geographical distribution of countries on the earth when visitors visit, thereby improving the display effect.

[0042] like Figures 1 to 4As shown, the dynamic display device includes: a display body 4, a driving component and a personnel detection component; wherein the display body 4 is provided with a suspension block and a central axis 43, and the suspension block is arranged on the surface of the display body 4, and is used to display the continental plates on the earth and the landform features of each country. By setting different shades of colors on the suspension block, or setting different protrusions or depressions on the suspension block, the altitudes or terrain features of different geographical locations can be distinguished, and the structural characteristics of the earth's continental plates are simulated. The suspension block can vividly and intuitively display geographical science knowledge.

[0043] like Figure 2 As shown, the central axis 43 is arranged inside the display body 4 and coincides with the geometric center position of the shape of the display body 4, which is conducive to keeping the main structure of the display body 4 stable during the rotation process. The display body 4 is connected to the central axis 43; the driving component is connected to the central axis 43, and is used to drive the display body 4 to rotate. The rotation torque of the driving component is transmitted to the display body 4 through the central axis 43, and the transmission efficiency is high and the transmission mode is stable, which is conducive to the long-term rotation of the display body 4; the personnel detection component is arranged at a predetermined position of the dynamic display device and is connected to the driving component signal. When the personnel detection component detects that there is personnel activity in the predetermined area, the personnel detection component is used to send a continuous trigger signal to the driving component, so that the driving component drives the display body 4 to rotate around the central axis 43.

[0044] The dynamic display device can realize autonomous start and stop of the dynamic display device based on the detection results of the personnel detection component. When the personnel detection component detects that there are visitors in the set area, it automatically triggers the display body 4 to rotate, thereby dynamically displaying the geographical distribution of countries on the earth. The dynamic display device not only realizes the automation of its own control method, but also optimizes the display effect, increases the interactivity of the dynamic display device, and improves the audience's enthusiasm for visiting. The overall shape of the display body 4 is unique, echoing the surrounding environment, and has a strong visual impact, so that the audience can learn corresponding knowledge in the process of interaction.

[0045] In some embodiments, the personnel detection component includes at least one of a visual camera, an infrared sensor, an ultrasonic sensor, a laser radar, a pressure sensor, and a sound sensor, but is not limited thereto. The personnel detection component may also use a combination of multiple detection methods to prevent misjudgment. If an infrared sensor is used, the infrared sensor should be set in the personnel viewing area; if a pressure sensor is used, the pressure sensor should be set on the ground around the dynamic display device.

[0046] In some embodiments, Figure 2As shown, the display body 4 is set to be a sphere or a shape similar to a sphere, which can not only better simulate the geographical features of various plates on the earth, but also simulate the rotation effect of the earth when the display body 4 rotates.

[0047] In some embodiments, Figure 3 and Figure 4 As shown, the driving assembly includes a rotary driving source 2 for providing power, a transmission mechanism 3 and a rotary support mechanism 1; the transmission mechanism 3 is connected to the rotary driving source 2 and the central shaft 43 respectively, and is used to transmit the torque of the rotary driving source 2 to the central shaft 43 of the display body 4, so that the display body 4 rotates; a cavity 14 is arranged inside the rotary support mechanism 1, and the transmission mechanism 3 is located inside the cavity 14. During the operation of the dynamic display device, the rotary driving source 2 can provide power for the rotation of the display body 4, and the motion state of the display body 4 can be changed by controlling the start or stop of the rotary driving source 2. The transmission mechanism 3 is arranged between the display body 4 and the rotary driving source 2, and is driven by gears or belts, so that most of the power of the rotary driving source 2 can be transmitted to the display body 4. The rotary support structure can provide bottom support for the structure of the display body 4.

[0048] In some embodiments, the rotary drive source 2 is one of an electric motor, a pneumatic motor and a hydraulic motor. Taking an electric motor (motor) as an example, Fig.11 As shown, an infrared sensing system is set up near the booth, and the infrared sensor is connected to the central control board at the same time. The central control board is connected to the air circuit of the rotating motor through wires to control the opening and closing of the rotating motor. The infrared sensing system usually consists of an infrared sensor, a processor, and related circuits. When a person or object passes through the area covered by the infrared sensor, the sensor detects the change of infrared rays and sends the signal to the processor for processing. The central control board can act as a centralized control unit (processor) to receive the signal sent by the infrared sensor and perform corresponding operations. The central control board is connected to the air circuit of the rotating motor through wires, which means that the central control board can control the opening and closing state of the rotating motor. With such a configuration, when the infrared sensor detects that a person or object passes by, it sends a signal to the central control board. Then, the central control board can connect or disconnect with the air circuit of the rotating motor through wires according to the preset logic or program, thereby controlling the operation or stop of the rotating motor.

[0049] In some embodiments, the transmission mechanism 3 is provided with a driving gear 31 and a driven gear, the driving gear 31 is eccentrically arranged with the rotation drive source 2, and the driven gear is concentrically arranged with the rotation drive source 2; this arrangement makes the center of gravity of the display body 4 on the rotation axis, the rotation process is smooth, and the shaking is reduced. In specific implementation, a gear pad can be designed between the driving gear 31, the driven gear and its supporting structure, and the gear pad can be used as a buffer material to absorb and reduce vibration and impact force in the transmission system, thereby protecting the gears and other transmission parts. The gear pad can provide a layer of buffer between the gears, reduce direct contact and friction between the gears, and thus reduce the noise and vibration of the transmission mechanism 3.

[0050] In some embodiments, the driving gear 31 is directly connected to the rotation driving source 2 or indirectly connected through a reducer, and the driven gear is connected to the central axis 43 of the display body 4, and is used to drive the display body 4 to rotate around the central axis 43. Optionally, the rotation driving source 2 can also use a reduction motor with an integrated reducer to save installation space. The motor shaft 21 and the driving gear 31 can be connected by a key.

[0051] In some embodiments, Figure 3 and Figure 4 As shown, the rotating support mechanism 1 is provided with a base and a slewing support member 15. As the supporting structure of the entire dynamic display system, the base not only supports the gravity above it, but also supports the rotating motion.

[0052] As a rotating support mechanism 1, a first flange 11 is provided on the top of the base, a second flange 431 is provided on the bottom of the display body 4, the slewing support member 15 includes an inner ring, an outer ring and a rotating body located therebetween, one of the inner ring and the outer ring is fixedly connected to the first flange 11, and the other of the inner ring and the outer ring is fixedly connected to the second flange 431, and the rotating support mechanism 1 is used to provide support for the rotating display of the display body 4.

[0053] The slewing support 15 can use a slewing support bearing specially used for slewing motion, which can withstand thrust or radial loads, rotate or continuously rotate at a low speed, has high transmission efficiency, stable transmission, can absorb vibration, has low noise, and has a wide range of uses; it usually consists of two inner and outer rings, with rolling elements (such as steel balls, rollers or sliding elements) and retainers in the middle. The slewing support bearing can withstand radial forces, axial forces and torques from all directions, and can support and carry a large amount of weight and torque. The slewing support bearing is designed to achieve 360-degree smooth slewing motion. It can achieve a large range of rotation in a small space, providing flexibility and functionality for the equipment. The slewing support bearing can accurately guide and position the slewing motion of the equipment, and maintain precise position and direction when the equipment is working. Compared with traditional bearing systems, the slewing support bearing has a compact structure and can significantly save the installation space of the equipment.

[0054] The motor gear mechanism is fastened to the upper plate with bolts. The motor gear mechanism is used in conjunction with the slewing bearing to achieve power transmission through gear meshing. It has a compact structure and is easy to maintain. It can work in harsh environments such as high temperature, low temperature, and corrosion. It requires regular maintenance and is relatively easy to install and disassemble.

[0055] In some embodiments, Figure 3 and Figure 4 As shown, the base also includes the base lower bottom plate 13 and an inner cylinder 16.
