Description

Technical Field

[0001] The present invention relates to the technical field of garden landscape equipment, and particularly to a garden light and shadow device. Background Art

[0002] In garden landscape design, light and shadow devices can greatly enhance the artistic atmosphere and ornamental value of gardens, bringing unique visual experiences to tourists;

[0003] However, existing garden light and shadow devices have many deficiencies. On the one hand, most of their light-transmitting plates are fixedly installed. When maintaining the device, updating the patterns of the light-transmitting plates or adjusting the layout of the device, the disassembly and assembly process is cumbersome, consuming a large amount of manpower and time costs. On the other hand, the control methods of traditional light and shadow devices are relatively single, mostly on-site manual control, and cannot flexibly and conveniently adjust the light and shadow effects according to different scenarios and time requirements. To solve these problems, the present invention proposes a garden light and shadow device, which improves the detachable combination method of the light-transmitting plates and realizes remote APP control to enhance the practicality and intelligent level of the garden light and shadow device;

[0004] Therefore, the present invention proposes a garden light and shadow device. Summary of the Invention

The box board is arranged between the upper fixing frame and the lower fixing frame. There are a total of four box boards, and two adjacent box boards are arranged in a rectangular distribution. Projection plates are provided on all four box boards. An annular sliding frame is provided at the top of the upper fixing frame, and the upper fixing frame is rotationally connected to the circular rail through the annular sliding frame.

[0008] Further, a driving motor is provided at the bottom of the upper fixing frame. The output end of the driving motor passes through the upper fixing frame and is connected to the bottom of the lamp cover top cover. An installation cover is provided outside the driving motor at the bottom of the upper fixing frame, and a projection lamp is provided at the bottom of the installation cover.

[0009] The beneficial effects of adopting the above further scheme are as follows: After the driving motor is powered on, its output end rotates, driving the lamp cover top cover connected thereto to rotate, so as to realize the switching of different patterns or light transmission effects of the lamp cover. The projection lamp in the installation cover projects light, which is filtered and refracted by the rotating lamp cover top cover, forming dynamic light and shadow in the garden space. The driving motor, the lamp cover top cover and the projection lamp cooperate with each other to make the light and shadow effect more rich and changeable. This design realizes the dynamic presentation of light and shadow, enhancing the ornamental and interestingness of the garden; The driving motor accurately controls the rotation of the lamp cover top cover, and the projection lamp emits light stably, ensuring the stability of the light and shadow effect; The modular structure is convenient for installation and maintenance. By replacing the lamp cover top cover, the light and shadow theme can be changed, improving the applicability and flexibility of the device and reducing the operation cost.

[0010] Further, strip-shaped sliding grooves are opened at one ends of the upper fixing frame and the lower fixing frame close to each other, and strip-shaped sliding blocks are arranged at one ends of the box plates far away from each other. The box plates are slidably connected to the strip-shaped sliding grooves through the strip-shaped sliding blocks.

[0011] The beneficial effects of adopting the above further scheme are as follows: The strip-shaped sliding blocks on the box plates and the strip-shaped sliding grooves of the upper fixing frame and the lower fixing frame form a slide rail type matching structure. Through manual pushing or auxiliary mechanical drive, the box plates can slide horizontally along the strip-shaped sliding grooves. During the sliding process, the strip-shaped sliding blocks are stably guided in the sliding grooves, avoiding the deviation of the box plates, realizing the opening, splicing or position adjustment of multiple box plates, and meeting the requirements of different use scenarios. This design is convenient for quickly changing the appearance form and spatial layout of the device, such as adjusting the combination mode of the box plates according to the needs of garden activities; The cooperation between the strip-shaped sliding blocks and the sliding grooves ensures the smooth sliding and accurate positioning of the box plates, enhancing the structural stability; At the same time, the modular sliding connection makes the disassembly, installation and maintenance of the box plates convenient, facilitating the replacement of damaged parts or the update of the appearance pattern of the box plates, reducing the use cost, and improving the flexibility and practicability of the device.

The controller controls the operation of each component of the device according to the instructions, such as adjusting the light brightness and controlling the sliding of the box panel. The storage battery supplies power to all components inside the electric control box and other power-consuming parts of the device. Under the control of the controller, the speaker can play prompt sounds, background music, etc., enhancing the interactivity. This control component realizes wireless intelligent control and improves the operation convenience; with the built-in storage battery and charging module, it gets rid of the limitation of external power sources, adapts to various garden scenarios, and the Bluetooth connection facilitates remote control, expanding the usage range. The speaker enriches the functions of the device and can be used for prompting operations and creating an atmosphere. Each module is integrated into the electric control box, with a compact structure, convenient for inspection and maintenance, enhancing the practicality and intelligent level of the device.

[0014] Further, a charging interface is provided on one side of the electric control box. The output end of the charging interface is electrically connected to the input end of the charging module, and the output end of the charging module is electrically connected to the input end of the storage battery.

[0015] The beneficial effects of adopting the above further solution are as follows: The charging interface is used to connect to an external power source, such as a charger or a solar charging device. When the external power source is connected, the current is transmitted through the charging interface to the charging module. The charging module performs processes such as voltage stabilization and rectification on the input current, converts it into an electrical energy form suitable for storage in the storage battery, and then transports it to the storage battery for storage. During this process, the charging module can also perform intelligent monitoring and adjustment of the charging process to ensure charging safety and efficiency. This design provides a stable power supply replenishment path for the device, enables the storage battery to be recycled, reduces the dependence on traditional mains electricity, and improves the device's endurance. Multiple charging methods adapt to different scenario requirements, enhancing the device's applicability. The intelligent processing and monitoring of the charging module can effectively protect the storage battery, extend its service life, and reduce maintenance costs. At the same time, the standardized charging interface is convenient for operation, improving the convenience and reliability of the device's use.

[0016] Further, a heightening base frame is provided at the bottom of the electric control box. The diameter of the heightening base frame is adapted to the diameter of the electric control box. A sealing sleeve is threadedly connected to the top of the electric control box, and the inner diameter of the sealing sleeve is adapted to the diameter of the speaker.

[0017] The beneficial effects of adopting the above further solution are as follows: The heightening base frame elevates the electric control box through stable support, avoiding direct erosion of the box body by rainwater and moisture on the ground. Its diameter is adapted to the electric control box to ensure stable support.

The structures of both are simple and practical, with convenient disassembly and assembly, reducing the maintenance difficulty and cost, while ensuring the overall sealing and stability of the electric control box, and enhancing the applicability of the device in complex garden environments.

[0018] Further, the output end of the Bluetooth module is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input ends of the speaker, the driving motor, and the projection lamp.

[0019] The beneficial effects of adopting the above further solution are as follows: The Bluetooth module is responsible for receiving control instruction signals from external devices such as mobile phone APPs, and converting them into electrical signals and transmitting them to the controller. The controller, as the core processing unit, parses the received instructions and sends corresponding electrical signals to the speaker, the driving motor, and the projection lamp respectively according to different instructions. For example, when receiving a music-playing instruction, the controller controls the speaker to emit sound; if it is a light and shadow transformation instruction, the driving motor drives the lampshade to rotate, and at the same time adjusts the brightness and color of the projection lamp to achieve functional linkage. This design realizes the wireless intelligent control of the device, allowing users to remotely and conveniently operate. Through the cooperation of the Bluetooth module and the controller, functions such as audio playback, mechanical movement, and light adjustment are integrated for management, improving the automation degree of the device. The coordinated work of multiple components can create diverse sound and light effects, enhancing the ornamental value and interest of the garden. At the same time, the modular connection method facilitates later maintenance and function expansion, reducing the equipment upgrade cost.

[0020] Further, a limiting component, which is composed of right-angle baffles and limiting guard plates arranged at the corners of the upper fixed frame. There are four right-angle baffles in total, and the four right-angle baffles are distributed in a rectangle, and the distance between adjacent two right-angle baffles is equal. The limiting guard plate is in contact with the box board.

[0021] The beneficial effects of adopting the above further solution are as follows: The four right-angled baffles are rectangularly distributed at the corners of the upper fixing frame, delimiting the boundary for the sliding of the box board. When the box board slides on the strip-shaped chute, the limit guard plate contacts the surface of the box board, restricting its sliding stroke through physical blockage to prevent the box board from sliding excessively and detaching from the chute. When the box board slides to the extreme position, the limit guard plate provides a reverse resistance, cooperating with the right-angled baffles to form a stable limit structure, ensuring that the box board slides within the specified area. The limit component effectively guarantees the safety and accuracy of the box board sliding, avoiding equipment damage or personal injury caused by out-of-control sliding. The clear sliding boundary facilitates the precise control of the box board combination form, meeting the diverse layout requirements. Its structure is simple and stable, reducing the risk of equipment failure and the maintenance frequency. At the same time, the stable limit function enhances the reliability of the overall structure of the device, improving the stability and durability of the garden light and shadow device during use.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0023] 1. In the present invention, the upper fixing frame is embedded in the annular slide rail through the annular sliding frame and can achieve flexible 360° rotation under the action of the driving motor. The four box boards are installed between the upper fixing frame and the lower fixing frame in a rectangular distribution, and the strip-shaped sliders on their sides cooperate with the strip-shaped chutes of the fixing frame to ensure sliding stability. The projection plates on the box boards can filter, refract, and project the light emitted by the projection lamps. As the upper fixing frame rotates, it drives the box boards and the projection plates to rotate synchronously, realizing the dynamic change of the light and shadow angles and patterns. This design of the light box component achieves the dynamic display effect of light and shadow, enhancing the interest and attraction of the garden landscape. The annular sliding structure makes the light box rotate smoothly, reducing mechanical friction loss and extending the service life of the equipment. The modular installation of the box boards is convenient for disassembly and maintenance, and the projection plates can be quickly replaced according to needs to adjust the light and shadow style. The overall structure is compact and stable, adapting to complex outdoor environments, providing diverse choices for creating garden night landscapes, and enhancing the spatial artistic atmosphere.

[0024] 2.

[0048] Working principle:

[0049] like Figure 1-8 As shown, the upper fixing frame 21 is embedded in the annular slide rail 12 at the bottom of the lampshade top cover 11 through the annular sliding frame 211 at the top, forming a connection structure that can rotate 360 degrees. The drive motor 212 is fixed to the bottom of the upper fixing frame, and its output end is connected to the lampshade top cover. After power is turned on, the motor drives the upper fixing frame and the box plate assembly to rotate synchronously to achieve dynamic changes in the light and shadow angle. The four box plates 22 are installed in a rectangular distribution between the upper fixing frame and the lower fixing frame 23. The strip sliders 221 on the side of the box plate cooperate with the strip slide grooves 24 of the fixing frame to form a slide rail sliding structure. The projection plate 222 on the box plate emits a projection light 214. The light is filtered, refracted and projected. When the box plate rotates with the upper fixing frame, the projection plate rotates synchronously to change the projection direction and pattern of the light, creating a dynamic light and shadow effect. The Bluetooth module 37 receives control instructions such as light and shadow transformation, music playback, etc. from external devices such as mobile phone APP, and transmits the signal to the controller 36. After parsing the instructions, the controller sends electrical signals to each execution component to control the speed and direction of the drive motor 212, adjust the light and shadow rotation speed, control the brightness and color of the spotlight 214, realize the lighting effect transformation, and control the speaker 34 to play background music or prompt sound to enhance the sound and light linkage experience.
