According to one aspect of the present disclosure, the present disclosure provides a photovoltaic power generation device (hereinafter may also be simply referred to as a power generation device). As shown in FIG. 1 and FIG. 2, the power generating device includes a driving assembly 200 and a supporting device 10 (the supporting device 10 in this embodiment may include a first lever 300, a second lever 400, a third lever 600, and a fourth lever 700 And a first bracket 500 and a second bracket 800, as described in detail below) and at least two layers of photovoltaic power generation units 900 (which are shown in Figs. 4, 6 and 7). In the exemplary embodiment of the present disclosure, the supporting device 10 is connected to the driving assembly 200, and at least two layers of photovoltaic power generation units 900 are disposed on the supporting device 10. The driving assembly 200 can drive the supporting device 10 to drive at least two layers of photovoltaic power generation units 900 to form a collapsing mechanism, that is, to form a vertical (vertical) stack (see FIG. 2), so as to enable photovoltaic power generation that receives light The unit 900 performs photoelectric conversion. The driving assembly 200 can also drive the supporting device 10 to drive at least two layers of photovoltaic power generation units 900 to form an expanded structure, that is, to form a horizontal (horizontal) distribution (see FIG. 1), so as to enable the photovoltaic power generation unit 900 to receive light. Perform photoelectric conversion. In fact, as shown in FIG. 1 and FIG. 2, the driving assembly 200 drives the supporting device 10 to expand in an obliquely upward direction. As a result, at least two layers of photovoltaic power generation units 900 are driven by the driving module 200 to expand the photoelectric conversion area of the photovoltaic power generation unit 900 and increase the amount of power generation. The at least two layers of photovoltaic power generation units 900 are driven to close by the driving module 200.
