[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, Example 1 of the present invention, a movable steel bar shelter that automatically closes when it rains, includes a canopy 5 with rollers. A drive mechanism is connected to the canopy 5 or the rollers to move the canopy 5 or rotate the rollers. The drive mechanism is connected to a raindrop sensor 1 via a control component. The raindrop sensor 1 is a circuit board with many unconnected metal strips. When raindrops, acting as conductors, land on the metal strips, they connect the circuits and generate a signal. When the raindrop sensor 1 senses rain, the control component receives the signal and controls the drive mechanism, causing the canopy 5 to unfold to protect the steel bars.

[0030] In this embodiment, the canopy 5 is a push-pull canopy, and the driving mechanism is arranged at the front end of the push-pull canopy.

[0031] Specifically, the driving mechanism includes a head 6 provided at the front end of the canopy 5, a driving wheel provided at the bottom of the head 6, and a driving motor 61 for driving the driving wheel to rotate. The driving motor 61 is provided inside the head 6. The driving motor 61 drives the driving wheel at the bottom of the head 6 to rotate, so that the head 6 moves, thereby driving the movement of the front end of the canopy, so that the push-pull canopy is unfolded into a steel bar rainproof.

[0032] In this embodiment, Figure 1 As shown, the head 6 adopts the head at the front end of the electric telescopic door in the prior art, and the motor inside it can be selected to have a higher power according to the force of pushing and pulling the canopy 5. The control component is arranged inside the head 6; the raindrop sensor 1 is arranged on the top or side of the head 6.

[0033] In addition, if Figure 2 As shown, the head 6 is provided with a fixed power supply 4 connected to the driving motor 61 for supplying power to the driving motor 61. The head 6 is provided with a mobile battery 7 connected to the raindrop sensor 1 for supplying power to the raindrop sensor 1.

[0034] Example 2 is different from Example 1 in that Figure 2 As shown, the control assembly includes a comparator 2 and a relay 3 connected to a raindrop sensor 1 and a drive motor 61. Comparator 2 can receive signals from raindrop sensor 1 to determine the amount of rain. Relay 3 can also receive signals from comparator 2 to control the activation of motor drive motor 61, thereby moving the machine head 6.

[0035] Example 3 differs from Example 2 in that, to facilitate control of the canopy's retraction or manual deployment and retraction, a control switch connected to the drive motor 61 is provided on the head 6. Furthermore, a controller and a signal receiver connected to the drive motor 61 may be provided within the head 6, along with a remote control. The remote control includes a signal transmitter connected to the signal receiver via a signal. The remote control may employ a conventional structure.

[0036] Example 4 is different from Example 2 in that, in order to ensure the unfolding trajectory of the awning, a track that cooperates with the rollers at the bottom of the awning can be set on the ground.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that any modification to the technical solutions described in the aforementioned embodiments, or any equivalent replacement of some or all of the technical features thereof, within the spirit and principles of the present invention, does not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and should all be included in the scope of protection of the present invention.
