The window includes glass and an inner window frame for installing the glass. The top of the inner window frame is hinged on the outer window frame. The bottom of the inner window frame can abut against the side of the outer window frame facing the outside. The photovoltaic panel is arranged on the facade of the building next to the window hole and is electrically connected to the driving motor so that the driving motor can be powered by the photovoltaic panel. The driving motor is connected to the rotating shaft of the inner window frame and can drive the bottom of the inner window frame to rotate toward the outside. A self-locking mechanism is provided in the driving motor. When the window needs to be opened, the user can start the driving motor to drive the inner window frame to flip to a certain angle toward the outside, and then use the self-locking mechanism to lock the driving shaft of the driving motor to maintain the inner window frame in a state of flipping toward the outside.

[0004] However, since the window always remains in a flipped state facing outdoors when it is opened, the wind blowing from outside the window hole into the window hole will constantly impact the window, causing the self-locking mechanism to bear a heavy load. When the external wind is strong, the self-locking mechanism is prone to damage, making it impossible for the solar photovoltaic thermal window to maintain the open state normally.

[0005] In view of this, it is necessary to provide a solar photovoltaic thermal window. Utility Model Content

The locking unit 33 is detachably connected to the slider 32 and can lock the slider 32 in the slide groove when connected to the slider 32.

[0038] Through the above design, when it is necessary to open the window, the user can first control the drive motor 13 to drive the bottom of the inner window frame 12 to rotate toward the outside, and the inner window frame 12 will drive the slider 32 to move toward the outer window frame 11 through the connecting rod; after the inner window frame 12 is rotated to a suitable angle, the self-locking mechanism in the drive motor 13 locks the drive shaft of the drive motor 13 to enable the inner window frame 12 to maintain the window opening position; finally, the locking unit 33 is connected to the slider 32 to lock the slider 32 in the slide groove through the locking unit 33, so that the window can be supported by the support assembly 3, sharing the load borne by the self-locking mechanism in the drive motor 13, so as to reduce the risk of damage to the drive motor 13.
