[0034] Please see Figure 1 , Figure 1 A perspective view of the landscape display device 100 provided in this embodiment is shown. The landscape display device 100 shown in this embodiment is illustrated using the keel 214 waterwheel as an example.

[0035] Please see Figure 2 and Figure 3 The landscape display device 100 includes a waterwheel assembly 2 and a lighting display structure 1. The waterwheel assembly 2 includes a support structure 21, blades 22, and a water trough 24. The water trough 24 is disposed on the support structure 21. The blades 22 are located above the water trough 24 and connected to the support structure 21, and the blades 22 are movable relative to the support structure 21 and / or the water trough 24. There are multiple blades 22. The lighting display structure 1 includes a lighting assembly 11 and a wireless power supply assembly 12. The lighting assembly 11 includes a light-emitting unit 111 and a support member 112. The light-emitting unit 111 is disposed on the support member 112, and the support member 112 is disposed on the blades 22. The wireless power supply assembly 12 includes components for... A transmitter 121 and a receiver 122 are electrically connected to an external power source. The receiver 122 and the transmitter 121 are electrically connected through a field. The receiver 122 is located on the support member 112 and is electrically connected to the light-emitting unit 111. The transmitter 121 is located on the support structure 21 and / or the water tank 24. When the receiver 122 is close to the transmitter 121 and within a preset distance, the receiver 122 is wirelessly connected to the transmitter 121, and the light-emitting unit 111 is turned on and emits light. When the receiver 122 is far away from the transmitter 121 and moves away from the preset distance, the receiver 122 is electrically disconnected from the transmitter 121, and the light-emitting unit 111 is turned off.

[0036] Please see Figures 4 to 6The number of light-emitting units 111 is multiple. To allow each light-emitting unit 111 to be turned on and off individually for better lighting effects, the number of receivers 122 corresponds one-to-one with the number of light-emitting units 111. This ensures that each light-emitting unit 111 turns on when it receives power from its corresponding receiver 122 and turns off when the receiver 122 disconnects from the transmitter 121. Specifically, each light-emitting unit 111 is an LED bead that can emit various colors of light, such as white, red, and blue, as needed. The light-emitting side of the LED bead faces outwards, making the light visible. The back of the LED bead is connected to the support member 112, which is located on the blade 22, allowing the LED bead to rotate with the blade 22, thus producing different lighting effects as the blade 22 rotates. One, two, or more LED beads can be installed on a single blade 22, depending on actual needs. In this embodiment, multiple LED beads are installed on a single blade 22 in an array. In this embodiment, "multiple" refers to two or more quantities.

[0037] The blade 22 includes a mounting position 221 and a light-transmitting element 222. Specifically, the mounting position 221 is a groove provided in the blade 22, and the light-transmitting element 222 covers the mounting position 221, allowing light emitted by the light-emitting unit 111 to pass through the light-transmitting element 222. The light-emitting unit 111 is located in the mounting position 221, and the light-transmitting element 222 covers the mounting position 221. Light emitted by the light-emitting unit 111 can be emitted through the light-transmitting element 222 and reflected onto the water tank 24 to form a lighting effect.

[0038] The number of transmitters 121 can be greater or less than the number of receivers 122; that is, one transmitter 121 can correspond to one receiver 122, or one transmitter 121 can correspond to multiple receivers 122. When one transmitter 121 corresponds to multiple receivers 122, one transmitter 121 establishes a wireless connection with multiple receivers 122, thereby providing power to multiple LED beads. The field generated by the transmitter 121 can be received by the receiver 122, thus establishing a wireless connection between them. Specifically, the transmitter 121 and receiver 122 establish a wireless connection through a field, which can be near-field coupling or far-field coupling; energy is transferred between them through this field, thereby establishing a wireless connection. Specifically, in this embodiment, the transmitter 121 and receiver 122 use electromagnetic induction technology to establish a wireless connection. When the transmitter 121 is connected to high-frequency alternating current, it generates an alternating magnetic field. The receiver 122 generates a current in the magnetic field through electromagnetic induction, thereby powering the light-emitting unit 111 and causing it to turn on and emit light. For wireless connection to be established, the two devices must be within a preset distance. When the preset distance is exceeded, i.e., when the receiver 122 is removed from the alternating magnetic field generated by the transmitter 121, the receiver 122 cannot generate current, thus turning off the light-emitting unit 111 and preventing it from emitting light. In other embodiments, the transmitter 121 and receiver 122 can also achieve wireless connection using magnetic resonance or radio waves to control the turning on and off of the light-emitting unit 111.

[0039] It is understood that when the receiver 122 moves along with the corresponding blade 22, when the blade 22 moves to a position near the transmitter 121, the receiver 122 on the blade 22 establishes a radio connection with the nearest transmitter 121, thereby providing power to the LED beads on the blade 22 and enabling the LED beads to light up. As the blade 22 continues to move, the receiver 122 on the blade 22 disconnects from the radioly connected transmitter 121 and establishes a radio connection with the next transmitter 121, thereby continuing to power the LED beads. When the blade 22 moves to a position without a transmitter 121, the receiver 122 leaves the field of the transmitter 121, causing the receiver 122 to disconnect from the transmitter 121, thereby turning off the LED beads.

[0040] In this embodiment, the transmitting end 121 includes a first circuit board 1212 and a transmitting coil 1221, the first circuit board 1212 being electrically connected to the transmitting coil 1221; the first circuit board 1212 is disposed on the support structure 21 and / or the water tank 24, thereby fixing the transmitting end 121 to the support structure 21 and / or the water tank 24. The receiving end 122 includes a second circuit board 1222 and a receiving coil 1221, the second circuit board 1222 being electrically connected to the receiving coil 1221 and the light-emitting unit 111 respectively, and the second circuit board 1222 being connected to the support member 112, thereby fixing the receiving end 122 to the blade 22 and moving with the blade 22. In this embodiment, the transmitting coil 1221 and the receiving coil 1221 are wirelessly connected through electromagnetic induction technology or magnetic resonance technology. In this embodiment, the first circuit board 1212 converts the input DC power into high-frequency AC power and drives the transmitting coil 1221 to generate an alternating magnetic field. The first circuit board 1212 includes an LC resonant circuit to improve energy transmission efficiency and a bridge inverter circuit to achieve high-frequency conversion. The control chip on the first circuit board 1212 dynamically adjusts the power and detects the status, providing overvoltage and overcurrent protection mechanisms to ensure efficient and safe energy transmission. The receiving coil 1221 captures the alternating magnetic field of the transmitting end 121 and generates an induced current using electromagnetic induction. This current is rectified and filtered by the second circuit board 1222 and converted into DC power to supply the LED beads. The driving circuit on the second circuit board 1222 integrates a DC-DC converter to achieve regulated output, supplying power to the LED beads and controlling the display color and on / off effect of the LED beads. The second circuit board 1222 also has a control module to monitor voltage and current, dynamically adjust charging parameters, and combine overvoltage and overcurrent protection, temperature monitoring, etc., to ensure electrical safety. The second circuit board 1222 is also equipped with a resonant capacitor to match the receiving coil 1221, so as to improve the energy coupling efficiency and realize efficient and stable wireless power conversion and utilization.

[0041] Continue reading 2 and Figure 3 The waterwheel assembly 2 further includes a drive assembly 23 for driving the blades 22 to rotate relative to the support structure 21 and / or the water tank 24. The drive assembly 23 is provided with the transmitting end 121. In this embodiment, the water tank 24 is fixedly connected to the end of the support structure 21 near the ground, and the water tank 24 is fixed relative to the support structure 21. Under the drive of the drive assembly 23, the blades 22 can rotate relative to the support structure 21. During the rotation, at least one blade 22 is located above the water tank 24, so that the light emitted by the LED beads on the blades 22 can be projected onto the water tank 24, thereby producing various lighting effects, such as the lighting effect of flowing water. This avoids the use of water flowing on the water tank 24, thus avoiding the occurrence of dangerous situations caused by water flow.

[0042] Specifically, the support structure 21 includes a bracket 211 for support, a first support plate 212 and a second support plate 213, and a keel 214. Multiple brackets 211 are erected on the ground to support the landscape display device 100. The first support plate 212 is connected to the end of the bracket 211 near the ground and is located above the water tank 24. At least one blade 22 is located between the water tank 24 and the first support plate 212. The second support plate 213 is connected to the bracket 211, is parallel to the first support plate 212, and is located on the side of the first support plate 212 away from the water tank 24. To ensure the light emitted by the LED beads is properly projected onto the water tank 24, the second support plate 213, the first support plate 212, and the water tank 24 are arranged sequentially from top to bottom. Specifically, the water tank 24 is located at the end of the support 211 near the ground, the second support plate 213 is located at the end of the support 211 away from the ground, and the first support plate 212 is located between the second support plate 213 and the water tank 24. The keel 214 connects multiple blades 22 sequentially, and its cross-section along its length is approximately elliptical. The keel 214 and the blades 22 rotate around the periphery of the first support plate 212 and the second support plate 213, with a portion of the blades 22 always positioned between the first support plate 212 and the water tank 24. This ensures that a portion of the light emitted by the LED beads is always projected onto the water tank 24, creating a flowing water effect.

[0043] The drive assembly 23 includes a drive wheel 231, a driven wheel 232, and a motor 233. The motor 233, the drive wheel 231, and the driven wheel 232 are all connected to the bracket 211 for fixation. The drive wheel 231 and the driven wheel 232 are respectively located at the two ends of the first support plate 212 and the second support plate 213. The elliptical structure formed by the blade 22 and the keel 214 surrounds the outside of the first support plate 212, the second support plate 213, the drive wheel 231, and the driven wheel 232. During operation, the motor 233 drives the drive wheel 231 to rotate, which in turn drives the blade 22 to rotate, thereby driving the driven wheel 232 to rotate, causing the blade 22 to rotate around the drive wheel 231 and the driven wheel 232.

[0044] In this embodiment, the first support plate 212, the second support plate 213, the driving wheel 231 and the driven wheel 232 are all provided with a transmitter 121, so that when the blade 22 moves to the vicinity of the first support plate 212, the second support plate 213, the driving wheel 231 and the driven wheel 232, the LED beads on the blade 22 can be electrically connected, thereby emitting light and generating a light effect.

[0045] When the blade 22 moves between the first support plate 212 and the water tank 24, the receiver 122 on this part of the blade 22 is wirelessly connected to the transmitter 121 on the first support plate 212, and the light-emitting unit 111 on this part of the blade 22 turns on and emits light. When the blade 22 moves to the side of the second support plate 213 away from the first support plate 212, the receiver 122 on this part of the blade 22 is wirelessly connected to the transmitter 121 on the second support plate 213, causing the light-emitting unit 111 on this part of the blade 22 to turn on and emit light. When the blade 22 rotates to the vicinity of the driving wheel 231 or the driven wheel 232, the receiver 122 on this part of the blade 22 is wirelessly connected to the transmitter 121 on the driving wheel 231 or the driven wheel 232, respectively, causing the light-emitting unit 111 on this part of the blade 22 to turn on and emit light. This configuration allows the blade 22 to emit light at the desired position during rotation, enabling the LED beads on the blade 22 to be wirelessly charged when they rotate to that position, thus turning on and emitting light to create a lighting effect.

[0046] To enhance the lighting effect, the first support plate 212, the second support plate 213, and the water tank 24 can all be made of transparent materials, so that when light is projected onto them, better lighting effects can be produced, such as breathing light effects, water flow or wave effects, etc.

[0047] In this embodiment, the brightness of the light emitted by the LED beads can be designed according to actual needs, thereby creating different brightness levels and producing different lighting effects. To achieve this effect, the landscape display device 100 in this embodiment also includes a control component for controlling the rotation speed of the drive component 23, so that the rotation speed of the blade 22 can be adjusted. The control component can also control the power supply of the transmitter 121 and the brightness and color of the emitted light of the LED beads, thereby controlling the lighting effect.

[0048] To enhance the fun and interactivity of the landscape display device 100, a stepping component 4 is also provided for visitors to step on. The stepping component 4 is connected to the drive component 23. When visitors step on the stepping component 4, it can drive the drive component 23. Depending on the speed of stepping, the drive component 23 produces different driving effects, thereby producing different lighting effects.

[0049] To enhance the visual appeal and allow users to understand the operation of the landscape display device 100, the device also includes landscape components and photoelectric components. The landscape components include a rice paddy model and a mound model. When the drive component 23, controlled by the control component, rotates the blades 22, the light emitted by the LED beads creates water flow or wave effects on the water tank 24. This also produces the effect of water flowing over the mound and rice paddy models, causing the rice paddy model to sway, thus completing the demonstration of the landscape display device 100's operation. To better and more intuitively demonstrate the principles or application scenarios of the model, visual and auditory displays can also be provided through the photoelectric components. For example, an LED screen can be set up to display the rice growth process, animal activities in the paddy field or pond, and sound effects such as water flow or wave sounds, irrigation sounds, and animal sounds can be played. This allows visitors to intuitively and three-dimensionally experience the device's operation, thereby gaining a better understanding of it and appreciating the charm of historical inventions.

[0050] Compared to existing technologies, the landscape display device 100 provided in this application adds a lighting display structure 1 to the waterwheel component 2, enabling the landscape display device 100 to enhance lighting effects and achieve various effects such as water flow effects through lighting, thereby eliminating the need to introduce water flow, reducing danger, and improving visual effects, increasing entertainment and fun; in addition, the use of a wireless power supply component 12 eliminates the need for cables and wires, making the blades 22 less affected when rotating, and can better restore the usage scene of the ancient dragon bone 214 waterwheel, making it closer to the usage scene in ancient times, and making it easier for the audience to understand and appreciate.
