Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Example 1

[0027] like Figure 1 As shown, a multifunctional park bench based on photovoltaic power generation includes a solar power supply component 1, which utilizes photovoltaic panels with shingled technology to convert solar energy into electrical energy with maximum efficiency, thus powering the multifunctional park bench. One end of the solar power supply component 1 is equipped with an energy storage and utilization component 2, which can store and utilize electrical energy and also add a charging function to the park bench. The other end of the solar power supply component 1 is equipped with a music playback component 3, and the top of the solar power supply component 1 is fixedly connected to the park bench backrest 4.

[0028] like Figure 2 As shown, a multifunctional park bench based on photovoltaic power generation is disclosed. A solar power supply component 1 provides electricity to the multifunctional park bench using photovoltaic power generation. The solar photovoltaic panel 104 is configured as a shingled photovoltaic panel. Mounting clamping blocks 105 are detachable from the park bench seat plate 101 via mounting bolts 107. Two mounting clamping blocks 105 are symmetrically arranged about the vertical central axis of the solar photovoltaic panel 104. The top surface of the solar photovoltaic panel 104 and the top surface of the park bench seat plate 101 are on the same horizontal plane. The solar photovoltaic panel 104 employs shingled technology and uses conductive... The solar cells are connected in parallel and stacked front to back, with no metal grid lines on the surface and no gaps between the cells. This fully utilizes the usable surface area of ​​the module, reduces the line loss of traditional metal grid lines, and thus significantly improves the conversion efficiency of solar energy to electrical energy. Furthermore, the photovoltaic panel mounting backplate 103 is pressed and fixed from both ends using detachable mounting clamping blocks 105, allowing the photovoltaic panel mounting backplate 103 to be disassembled and installed. This facilitates the disassembly and replacement of the solar photovoltaic panel 104 when it is damaged, ensuring the normal power supply of this park bench.

[0029] like Figure 4 and Figure 5 As shown, a multifunctional park bench based on photovoltaic power generation includes an energy storage and utilization component 2 for storing and rationally allocating electrical energy. A wireless charger 206 is electrically connected to a voltage regulator 203, which in turn is electrically connected to a battery 202. The battery 202 is also electrically connected to a solar photovoltaic panel 104. A protective sliding plate 208 forms a sliding structure with the first leg 201 via a sliding groove 207. Two sliding grooves 207 are symmetrically arranged about the vertical central axis of the protective sliding plate 208. A first magnet 209 forms a magnetic connection with the first leg 201 via a second magnet 210. The adsorption structure allows the battery 202 to store the electrical energy converted from the photovoltaic panel and release it during use, facilitating the rational allocation of electrical energy. A voltage regulator 203 works in conjunction with the battery 202 to regulate its output voltage, ensuring a more stable output voltage and preventing damage to the user's electronic products due to voltage instability. It offers both USB and wireless charging options for enhanced convenience. A sliding protective plate 208 is located on the outside of the USB charging port 204, allowing it to be opened or closed to protect the USB charging port 204.

[0030] like Figure 3As shown, a multifunctional park bench based on photovoltaic power generation includes a music playback component 3 for playing music using a Bluetooth speaker 302 to enhance entertainment. The inner cavity of the second leg 301 is connected to the outer cavity of the second leg 301 through a sound outlet hole 307. The rain cover 308 is semi-circular in shape. The heat dissipation fins 305 are evenly spaced on the back of the heat conduction plate 304, and both the heat dissipation fins 305 and the heat conduction plate 304 are made of aluminum-copper alloy. The Bluetooth speaker 302 allows users to play their favorite music while resting. The heat conduction plate 304 and heat dissipation fins 305 are tightly attached to the back of the Bluetooth speaker 302 to dissipate the heat generated by the speaker, preventing overheating from affecting its lifespan. The sound outlet hole 307 does not obstruct the sound from being transmitted outward, and a rain cover 308 is provided on the top of each sound outlet hole 307 to prevent rainwater from falling in.

[0031] Working principle: The solar photovoltaic panel 104 adopts shingled technology and uses conductive adhesive in parallel to maximize power. During sunny periods, the solar photovoltaic panel 104 absorbs solar energy and converts it into electrical energy, which is then transmitted to the battery 202 for storage via wires. If the solar photovoltaic panel 104 is damaged after prolonged use of the park bench, the disassembly bolt 107 can be unscrewed with a tool, allowing the mounting clamping block 105 and sealing ring 106 to be removed. After the clamping limit of the mounting clamping block 105 is removed, the photovoltaic panel mounting back plate 103 and the solar photovoltaic panel 104 can be removed and replaced. The new solar photovoltaic panel 104 is installed on the top of the park bench, and its bottom wires are connected to the battery 202 to continue providing power to the multi-functional park bench. During the production process, a transparent protective layer of plastic material can be set on the top surface of the solar photovoltaic panel 104 to prevent power leakage.

[0032] When users resting on this park bench need to charge their mobile phones, they can simply place their phones on the wireless charger 206. The electrical energy stored inside the battery 202 is delivered to the wireless charger 206 through the voltage regulator 203 to charge the user's mobile phone. When other electronic products such as tablets and headphones need to be charged, the protective sliding plate 208 can be slid upwards to allow the first magnet 209 to be attracted to the second magnet 210 for fixation. Then, the charging cable can be inserted into the USB charging port 204 for charging. After charging is complete, the charging cable can be unplugged and slid downwards to allow the first magnet 209 to be attracted to the third magnet 211 for fixation. The protective sliding plate 208 can then block the outside of the USB charging port 204 for protection.

[0033] The light strip 102 is electrically connected to the voltage regulator 203, and a photosensitive relay is installed inside the light strip 102. When it gets dark, the light strip 102 can emit light to illuminate the road and enhance the aesthetics of the park.

[0034] When a user sits on this park bench, they can also connect to a Bluetooth speaker 302 via Bluetooth to play their favorite music. During playback, the sound from the Bluetooth speaker 302 can be emitted outward through the sound outlet 307, and the heat dissipation position on its back is in close contact with the heat conduction plate 304. The aluminum-copper alloy material has excellent thermal conductivity, and the heat dissipation fins 305 can dissipate heat outward.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
