Description

Technical Field

[0001] This utility model relates to the field of new energy application technology, and in particular to an environmentally friendly umbrella frame for solar power generation. Background Technology

[0002] The umbrella, as an ancient and widely used portable tool for sun and rain protection, has maintained its basic form for thousands of years. With modern life's increasing demands for portability and functionality, folding umbrellas have become increasingly popular due to their small size and lightweight design. However, traditional umbrellas are essentially passive protective devices, their function limited to providing shade, failing to actively collect or utilize the abundant environmental energy acting upon them, especially the most prevalent and intense solar energy.

[0003] In the sweltering summer, especially in low-latitude or high-UV-index regions, using umbrellas for sun protection is a common and effective way for pedestrians to shield themselves from the scorching sun and prevent UV damage. At this time, the open umbrella surface is directly exposed to intense solar radiation, accumulating and absorbing a large amount of solar energy. This solar energy is usually converted into heat energy and dissipated into the environment in the form of thermal radiation. People carrying or shouldering umbrellas under the blazing sun essentially have a natural, portable, small solar energy collection platform above their heads, but lack the corresponding technological means to convert this energy into valuable energy.

[0004] The abundant solar energy received by the umbrella is not being effectively captured and utilized, which is undoubtedly a huge waste of resources, especially given the large amount of solar energy present. Upgrading it to a mobile micro-power generation device with energy harvesting capabilities would realize its dual environmental value of collecting green energy and reducing carbon emissions. Utility Model Content

[0005] To overcome the shortcomings of limited functionality, a multifunctional and environmentally friendly umbrella frame that generates solar power is provided.

[0006] An environmentally friendly solar-powered umbrella frame includes a support rod with a handle connected to its bottom. Several umbrella ribs are mounted on the top of the support rod, with an umbrella canopy laid between the ribs. A fixing plate is connected to the top of the support rod, and mounting frames are rotatably connected to both sides of the fixing plate. Solar panels are installed within the mounting frames. A torsion spring is fitted onto a pivot shaft connecting the mounting frames and the fixing plate. One end of the torsion spring is connected to the pivot shaft of the mounting frames, and the other end is connected to the fixing plate. The support rod is equipped with an environmentally friendly component for energy reuse.

[0007] Optionally, the environmentally friendly component includes an adapter ring, a wire groove is opened in the support rod, a storage battery is provided at the upper end of the support rod, a charging controller connecting the solar panel and the storage battery is provided in the fixing plate, the adapter ring is rotatably connected to the top of the handle, the adapter ring is provided with a charging port, and the external charging cable of the storage battery is connected to the adapter ring through the wire groove.

[0008] Optionally, a baffle is connected to the outer side of the lower end of the support rod, and a protruding rod is connected to the top of the adapter ring. The baffle and the protruding rod are in a limiting fit. The support rod located in the inner ring of the adapter ring has several grooves. A top block is slidably connected inside the adapter ring. The top block is slidably connected to the support rod through the grooves. A return spring is provided inside the adapter ring. One end of the return spring is connected to the adapter ring, and the other end is connected to the top block.

[0009] Optionally, the outer ring of the adapter ring is connected to an anti-slip pad.

[0010] Optionally, the bottom of the mounting frame is rotatably connected to a roller.

[0011] Optionally, protective covers are connected to both ends of the top of the fixing plate, and the protective covers cover the torsion spring.

[0012] Optionally, a light is installed at the connection between the support rod and the umbrella rib, and the light is wired to the battery.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0022] Example: An environmentally friendly umbrella frame that generates solar power, such as Figures 1-5 As shown, the umbrella includes a support rod 1, a handle 2, umbrella ribs 3, umbrella canopy 4, a fixing plate 5, a mounting frame 6, a solar panel 7, a torsion spring 8, and an environmentally friendly component. The handle 2 is fixedly connected to the bottom of the support rod 1. Several unfoldable umbrella ribs 3 are installed on the top of the support rod 1, and the umbrella canopy 4 is laid between the umbrella ribs 3. The fixing plate 5 is also fixedly connected to the top of the support rod 1. The mounting frame 6 is rotatably connected to both sides of the fixing plate 5 through a pivot. The solar panel 7 is fixedly installed inside the mounting frame 6. A torsion spring 8 is sleeved on the pivot connecting the mounting frame 6 and the fixing plate 5. One end of the torsion spring 8 is fixedly connected to the pivot of the mounting frame 6, and the other end is fixedly connected to the fixing plate 5. The support rod 1 is equipped with an environmentally friendly component for energy reuse.

[0023] like Figure 2 and Figure 4 As shown, the environmental protection component includes a battery 10 and an adapter ring 11. A wire groove 9 for wiring is provided inside the support rod 1. The battery 10 is installed at the upper end of the support rod 1. A charging controller connecting the solar panel 7 and the battery 10 is installed inside the fixing plate 5. The top of the handle 2 is sleeved and rotatably connected to the adapter ring 11. The adapter ring 11 is provided with a charging port 12. The output end of the battery 10 is connected to the circuit inside the adapter ring 11 through the wires laid in the wire groove 9, and finally connected to the charging port 12.

[0024] like Figure 4 and Figure 5As shown, it also includes a baffle 13, a protruding rod 14, a top block 16, and a return spring 17. The lower outer side of the support rod 1 is connected to the baffle 13. The end of the adapter ring 11 away from the handle 2 is connected to two protruding rods 14. The protruding rods 14 cooperate with the baffle 13 to limit the rotation angle range of the adapter ring 11. On the cylindrical surface of the support rod 1 surrounded by the inner ring of the adapter ring 11, there are several grooves 15 distributed circumferentially. The top block 16 is slidably connected inside the adapter ring 11. The top block 16 is slidably connected to the support rod 1 through the grooves 15. The return spring 17 is provided inside the adapter ring 11. One end of the return spring 17 is connected to the adapter ring 11, and the other end is connected to the top block 16.

[0025] like Figure 4 As shown, it also includes an anti-slip pad 18, and the outer ring of the adapter ring 11 is connected to the anti-slip pad 18 to increase friction and facilitate manual rotation.

[0026] like Figure 3 As shown, it also includes a roller 19. The bottom of the mounting frame 6 is rotatably connected to the roller 19, which is used to roll on the umbrella surface 4 to reduce friction.

[0027] like Figure 1 As shown, it also includes a protective cover 20. The top two ends of the fixing plate 5 are connected to the protective cover 20. The protective cover 20 wraps around the torsion spring 8 and serves to prevent dust, water and foreign objects.

[0028] like Figure 2 As shown, it also includes a lighting lamp 21. The lighting lamp 21 is installed at the connection between the support rod 1 and the umbrella rib 3, and the lighting lamp 21 is wired to the storage battery 10.

[0029] When the user opens the umbrella, the umbrella ribs 3 unfold, tautning the canopy 4. The taut canopy 4 pushes the mounting frame 6 upward. Since the bottom of the mounting frame 6 contacts the canopy 4 via rollers 19, the mounting frame 6 can smoothly rotate outward around the pivot at the top of the fixing plate 5, simultaneously exposing the internal solar panel 7 to sunlight. This unfolding process twists the torsion spring 8 fitted on the pivot, allowing it to accumulate elastic potential energy. Once fully unfolded, the solar panel 7 receives sunlight and converts it into electrical energy. A charging controller integrated within the fixing plate 5 regulates this electrical energy and safely stores it in the battery 10 at the top of the support rod 1. When the user needs to charge external devices, such as mobile phones or small fans, they simply insert the charging cable into the charging port 12 on the adapter ring 11. The charging controller manages the discharge process, providing a stable output voltage through the adapter ring 11, and automatically cuts off the output to protect the battery when the battery 10 voltage is too low, thus achieving the collection and utilization of clean solar energy and achieving environmental protection goals. When closing the umbrella, the user needs to first unplug the charging cable. Then, the torsion spring 8 releases the stored elastic potential energy, driving the mounting frame 6 to rotate in the opposite direction and reset, so that the solar panel 7 fits against the outer surface of the closed umbrella 4.

[0030] When using the charging port 12 to power the device, the user can manually rotate the adapter ring 11. This operation aims to adjust the orientation of the charging port 12, making it easier to plug and unplug the charging cable, especially when alternating between holding the umbrella handle with both hands to operate the device. To ensure that the adapter ring 11 rotates smoothly and does not rotate indefinitely, the baffle 13 and the protruding rod 14 cooperate to limit the adapter ring 11 from rotating 360°. During the rotation of the adapter ring 11, the top block 16 inside slides along the groove 15 on the support rod 1. When the top block 16 slides to the edge of the groove 15 or needs to cross the protrusion between the grooves, the sidewalls between the grooves 15 push the top block 16 to move inward into the adapter ring 11, thereby compressing the return spring 17. When the adapter ring 11 stops rotating and the top block 16 is aligned with the groove 15, the return spring 17 releases its elastic force to push the top block 16 back into the groove 15. This engagement structure produces a slight damping and positioning feel, effectively preventing the adapter ring 11 from shaking or rotating arbitrarily when not in operation. In addition, the anti-slip pad 18 wrapped around the outer ring of the adapter ring 11 significantly increases the friction, making it easier for the user to apply force when rotating the adapter ring 11 and making it easier to hold the umbrella handle.

[0031] In nighttime or dimly lit environments, the user can turn on the light 21 installed at the connection between the support rod 1 and the umbrella rib 3. Powered by the battery 10, this light effectively illuminates the ground beneath the user's feet, enhancing safety during nighttime walking. The inner side of the umbrella surface 4 typically has a reflective coating or light-colored material that reflects the light from the light 21 downwards, further enhancing the lighting effect. Protective covers 20 located at both ends of the top of the fixing plate 5 prevent dust, rainwater, and other foreign objects from entering and causing the torsion spring 8 to jam or fail. They also prevent the torsion spring 8 itself from corroding due to exposure, ensuring its elastic function remains reliable over the long term.

[0032] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
