[0037] The usage process of this utility model is as follows:

[0038] S1. Initial state: The electric telescopic mechanism is in the retracted state, such as... Figure 1 As shown, both the lower movable support 2 and the upper movable support 3 are retracted into the cover 1;

[0039] S2, Lower movable support 2 unfolds: The telescopic rod of electric cylinder 4-2 extends, and the telescopic rod drives the first movable base 4-6 to move toward the corresponding first fixed base 4-7. At the same time, the second movable base 4-4 moves toward the corresponding second fixed base 4-5. During the movement of the first movable base 4-6 and the second movable base 4-4, the first and second umbrella rib support structures are driven to unfold. The pulley 5 slides along the C-shaped pulley groove 2-6, and the lower movable support 2 drives the upper movable support 3 to unfold.

[0040] S3. Upper movable support 3 unfolds: When the electric telescopic mechanism 4 drives the lower movable support 2 to move outward to the end of its stroke, that is, when the first slide rail 2-1 slides outward along the first slide groove 1-1 to the end of its stroke, the first slide rail 2-1 activates the touch switch. The touch switch controls the micro motor to drive the gear 2-3 to rotate forward. The gear 2-3 unfolds outward through the rack 3-1. The driven mechanism ensures smooth movement during the unfolding process through the cooperation of the slide rail and the slide groove until the upper movable support 3 is fully unfolded and the micro motor stops rotating.

[0041] When both the lower movable support 2 and the upper movable support 3 are in the extended state, the solar panels installed on the cover 1, the lower movable support 2 and the upper movable support 3 fully receive sunlight and convert it into electrical energy at full load.

[0042] S4. The upper movable support 3 and the lower movable support 2 retract synchronously: The electric cylinder 4-2 and the micro motor receive the action signal at the same time. The telescopic rod of the electric cylinder 4-2 retracts inward, and the micro motor reverses until the upper movable support 3 and the lower movable support 2 retract synchronously into the cover 1, completing the retraction of the telescopic solar panel support. The cover 1 protects the solar panels installed on the lower movable support 2 and the upper movable support 3.

[0043] Based on this, the present invention can also be combined with existing technologies to further expand its application. For example, a control module and an environmental monitoring module can be installed on the telescopic solar panel bracket, and the converted electrical energy can power both of them. The control module is used to receive environmental information (including airflow, temperature, light intensity and rainfall, etc.) monitored by the monitoring module, and then control the electric cylinder 4-2 to start according to the environmental information.

[0044] This application enables the upper movable support 3 and the lower movable support 2 to be retracted into the housing 1 by activating the electric cylinder 4-2 when the external environment is harsh or the light intensity is weak, thus protecting the solar panel. Conversely, when the external environment is suitable, the upper movable support 3 and the lower movable support 2 are extended by controlling the electric cylinder 4-2, thus meeting the requirements of the solar panel to convert solar energy into light energy.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
