The power module includes a photovoltaic unit 130 that converts absorbed light energy into electrical energy. The photovoltaic unit 130 is disposed at the top of the shed body 120. Since the shed body 120 is located at the highest position from the ground and has less occlusion, the photovoltaic unit 130 can absorb more light. Depending on the shape of the charging device 102, the photovoltaic unit 130 may be placed at a side or the like for ease of installation.

Even if a rainy weather occurs for a long time, since the general self-mobile device 101 is provided with a rain shower module, it can automatically return to the charging device 102 when it rains, so the working time from the mobile device 101 is reduced, and the required electric energy is reduced, and the battery 150 is reduced. The stored power can be maintained without powering through other power supplies.

The circuit assembly 140 also includes a conversion circuit 143 that connects the photovoltaic unit 130 and the battery 150, respectively.

The connection mode is relatively flexible, and the photoelectric conversion module 100 is independently installed in the vicinity of the existing charging device 102 or mounted on the charging device 102, so that the shed body 120 is located above the charging device 102, since the existing charging device 102 includes The power adapter connected to the AC interface can use the power adapter as the electrical connector. The photoelectric conversion module 100 can output the AC supply voltage to the charging device 102 as long as the power adapter is electrically connected to the AC interface. Since the AC supply voltage outputted by the photoelectric conversion module 100 is a standard civilian AC voltage, it can be matched with the charging device 102. In this way, the user can use it in combination with the photoelectric conversion module 100 without changing the existing charging device 102, which not only saves energy but also avoids using an excessively long power cord. Further, since the shed body 120 is disposed at the top, the self-moving device 101 of the regenerative charging device 102 can be shielded from light or rain, and the aging or malfunction of the components of the mobile device 101 due to illumination or rain can be reduced.

The mobile device 101 may not require an external power adapter or the like, and only needs to be electrically connected to the DC input interface of the charging device 102 and the DC interface of the photoelectric conversion module 100. The photoelectric conversion module 100 can supply power to the charging device 102 through the electrical connector having the corresponding interface. For example, if the DC input voltage of the charging device 102 is 20V, the DC/DC conversion circuit converts the output voltage of the photovoltaic unit 130 or the battery 150 into a 20V DC voltage. Further, the conversion circuit 143 can also be set to adjust the parameters, and the supply voltage outputted by the conversion circuit 143 can be changed by adjusting the corresponding parameters, so that the voltage adjustment can be performed according to different electrical devices connected to the photoelectric conversion module 100.

In some embodiments, the connector further includes a mechanical connector that can securely couple the photoelectric conversion module 100 to the charging device 102. The mechanical connector includes a mounting on the bracket 110 for mounting the charging device 102 Installation location (not shown).
