Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1 , Figure 2 and Figure 3A photovoltaic table according to an embodiment of this utility model includes a table leg assembly 100, a table body assembly 200, and an energy processing assembly 300. The table leg assembly 100 is height-adjustable. The table body assembly 200 includes a table frame 210, a tabletop 230, and a solar cell 220 for low-light power generation. The table frame 210 is rotatably connected above the table leg assembly 100. The table frame 210 has a receiving groove 211, in which the solar cell 220 is disposed. The tabletop 230 covers the open end of the receiving groove 211 and is transparent. The tilt angle of the tabletop 230 relative to the ground is adjustable. The energy processing assembly 300 is electrically connected to the solar cell 220 and is used to process the electrical energy generated by the solar cell 220.

[0023] Solar cell 220 may include perovskite cells, which (such as MAPbI3) have bipolar carrier transport characteristics and an adjustable bandgap (around 1.5 eV), and can efficiently absorb visible to near-infrared light (wavelength 300-800 nm). They have high defect tolerance, maintaining high carrier mobility even with small amounts of impurities or grain boundaries.

[0024] Solar cells 220 can also be cadmium telluride cells, amorphous silicon cells, etc., and can generate electricity even under low light conditions.

[0025] The table leg assembly 100 is height-adjustable, making the photovoltaic table highly adaptable and improving the user experience. The solar cell 220 can generate electricity even in low light conditions, effectively capturing photons and converting them into electrical energy. The power processing component processes the electricity generated by the solar cell 220 and outputs it for user convenience. The tabletop 230 provides support and allows light to pass through. The table frame 210 is rotatably connected to the table leg assembly 100. The tilt angle of the tabletop 230 relative to the ground is adjustable, allowing the angle at which the solar cell 220 receives sunlight to be adjusted according to the direction of sunlight, thereby maximizing the utilization of sunlight and improving the quality and efficiency of light energy conversion into electrical energy. It also facilitates storage and portability. The adjustable tilt angle of the tabletop 230 relative to the ground and the height of the photovoltaic table enhance the flexibility and practicality of actual use.

[0026] In some embodiments, see Figure 2 , Figure 3 and Figure 4The table leg assembly 100 includes a base 110, a support rod 120, and a height adjustment bolt 130. The base 110 has a sliding groove 1121, through which the lower end of the support rod 120 slides. The table frame 210 is rotatably connected to the upper end of the support rod 120. The base 110 has a threaded hole 1122 communicating with the sliding groove 1121. The height adjustment bolt 130 is threadedly connected to the threaded hole 1122, and is used to fix the support rod 120 to the base 110. Rotating the height adjustment bolt 130 outwards allows the lower end of the support rod 120 to move up and down within the sliding groove 1121. Tightening the bolt 130 then presses against the support rod 120, preventing the lower end of the support rod 120 from moving within the sliding groove 1121, thus adjusting the overall height of the table leg assembly 100.

[0027] In some embodiments, see Figure 2 , Figure 3 and Figure 4 The support rod 120 has multiple limiting grooves 121 spaced apart along its axial direction. These grooves allow the lifting adjustment bolts 130 to extend into them. The lifting adjustment bolts 130 extend into the limiting grooves 121, restricting the movement of the inner wall of the grooves 121, thereby limiting the axial movement of the support rod 120 and ensuring that the lifting adjustment bolts 130 can securely limit the support rod 120 to a suitable height.

[0028] In some embodiments, see Figure 2 , Figure 3 and Figure 4 The base 110 includes two base rods 111, two support tubes 112, and a crossbar 113. The two base rods 111 are arranged in parallel, and the two support tubes 112 are respectively connected to the upper middle part of the two base rods 111. The two ends of the crossbar 113 are respectively connected to the two support tubes 112. There are two support rods 120, and each of the two support tubes 112 is provided with a sliding groove 1121. The lower ends of the two support rods 120 slide through the two support tubes 112 respectively. The base 110, including the base rods 111, support tubes 112, and crossbar 113, makes the overall structure of the base 110 stable and ensures the support stability of the table leg assembly 100.

[0029] In some embodiments, see Figure 1 , Figure 2 and Figure 3 Both ends of the base rod 111 are detachably connected to shock-absorbing sleeves 114. The shock-absorbing sleeves 114 can protect the base rod 111 and also reduce the noise generated during the movement of the photovoltaic table.

[0030] In some embodiments, see Figure 1 , Figure 3 and Figure 5The power processing component 300 includes an overvoltage protection module 310, a voltage regulation module 320, a power storage module 330, and a backup power supply 340. The power storage module 330 stores the electrical energy output by the solar cell 220. The voltage regulation module 320 adjusts the voltage output by the power storage module 330. The overvoltage protection module 310 limits the voltage generated by the solar cell 220. The backup power supply 340 supplies power to the voltage regulation module 320 when the output power of the solar cell 220 is insufficient. When light shines on the solar cell 220, the solar cell 220 absorbs light energy and converts it into electrical energy. The generated electricity is stored in the power storage module 330. The output voltage is adjusted by the voltage regulation module 320 and transmitted to the power output terminal. The overvoltage protection module 310 has an internal overvoltage protection circuit. The overvoltage protection module 310 limits the voltage generated by the solar cell 220 and can use overvoltage protection devices such as diodes or rheostats. The backup power supply 340 is connected to the voltage adjustment module 320. When the output power of the solar cell 220 is insufficient, it supplies power to the voltage adjustment module 320, providing a more stable power supply for charging external devices.

[0031] In some embodiments, see Figure 1 , Figure 3 and Figure 5 The photovoltaic table also includes a power output module 400, which is electrically connected to a voltage regulation module 320. The power output module 400 is used to output electrical energy. The solar cells 220 convert solar energy into electrical energy, which is then processed by the power processing component 300 and finally output by the power output module.

[0032] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The power output module 400 includes a power output interface 410, which is located on the side of the table frame 210. The power output interface 410 includes a USB interface 411 and a socket 412. The USB interface 411 and socket 412 allow for convenient wired charging of devices such as mobile phones.

[0033] In some embodiments, see Figure 1 , Figure 3 and Figure 5 The power output module 400 includes a wireless charging coil 420. A wireless charging indicator 231 is provided on the tabletop 230, and a charging progress bar display window 232 is also provided on the tabletop 230. The wireless charging coil 420 is located within the table frame 210 corresponding to the position of the wireless charging indicator 231. The wireless charging coil 420 is provided to facilitate wireless charging of mobile phones and other wireless charging devices.

[0034] In some embodiments, see Figure 1 , Figure 2 and Figure 3 Solar cell 220 is a low-light photovoltaic cell, comprising both rigid and flexible perovskite modules. Perovskite solar cells belong to the third generation of solar cells, utilizing perovskite-type organometal halide semiconductors as light-absorbing materials. They possess advantages such as high photoelectric conversion efficiency, low-light power generation, and low cost. Solar cell 220 can achieve efficient power generation under low-light conditions, is unaffected by weather, and can be used both indoors and outdoors, further expanding its application scenarios.

[0035] In some embodiments, see Figure 1 , Figure 2 and Figure 3 An angle adjustment switch 140 is provided at the connection between the table frame 210 and the table leg assembly 100. The angle adjustment switch 140 is used to adjust the tilt angle of the tabletop 230 relative to the ground. Two clamping plates are provided below the table frame 210. The upper end of the support rod 120 extends between the two clamping plates. The two clamping plates and the support rod 120 are connected by bolts. One end of the bolt is fixed to one of the clamping plates, and the other end is connected to a nut. The angle adjustment switch 140 is connected to the nut. Rotating the angle adjustment switch 140 adjusts the tightness of the nut and bolt. When the nut and bolt are loose, the table frame 210 can be rotated, thereby adjusting the tilt angle of the tabletop 230 relative to the ground. Tightening the nut by the angle adjustment switch 140 clamps the upper end of the support rod 120 with the two clamping plates, preventing the table frame 210 from rotating relative to the support rod 120, thus maintaining the tilt angle of the tabletop 230 relative to the ground.

[0036] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
