Description

Inductive automatic retractable awning

The invention relates to an inductive automatic retractable awning. In particular, after receiving a long-range signal or a short-range signal generated by a distance sensor through a processor, the driving member is then controlled to drive the retractable awning body to execute an unfolding command or a folding instruction. The invention of instructions.

Regardless of businesses or residences, awnings or awnings can be installed on the external doors and windows. In the early days, awnings or awnings needed to be manually driven to expand or close. Nowadays, awnings or awnings are gradually driven by electricity. Instead, the awning or awning can be unfolded or folded with the push of a button, eliminating the need for humans to do it manually.

Although electric drive can reduce human physical exertion, when the weather changes suddenly and requires the use of awnings or awnings, it is still necessary to rely on human judgment and press the button to perform the unfolding or folding function, which is really inconvenient. Therefore, China Announcement No. CN203049953U of the People's Republic of China proposes an automatic sunshade and rain awning, which includes an awning body, a light sensor, a rain sensor, a controller and a drive motor, wherein the light sensor, the rainwater The sensor and the controller are connected by signals to each other. When the light sensor senses strong light or the rain sensor senses rain, the controller will control the drive motor to unfold the awning body. If the controller does not receive a signal from strong light or rain, the controller will control the drive motor to fold the awning body.

However, this creation is only designed to sense light or rain, and then control the expansion or folding of the awning body. If a large vehicle or large object is gradually approaching and the awning body is in an unfolded state, it will not be able to automatically close it. There is a risk of damage to the awning body due to impact.

Therefore, the inventor proposes an inductive automatic telescopic awning so that the awning or awning can sense the approaching distance of a large vehicle or large object and automatically fold or unfold without having to bear the threat of damage due to collision. The awning is used to sense the approaching distance of a foreign object and automatically expand or collapse, including: a telescopic awning body with a fixed end and a movable end. The telescopic awning body includes a rotating shaft. Connected to a driving component; a distance sensor, disposed on the retractable awning body, the distance sensor senses the approaching distance of the foreign object and generates a long-range signal or a short-range signal; a processor, the signal The driving member and the distance sensor are connected. After receiving the long-range signal, the processor controls the driving member to drive the rotating shaft to make the movable end move away from the fixed end and execute an unfolding command, or the processor receives the After receiving the close-range signal, the driving member is controlled to drive the rotating shaft to make the movable end approach the fixed end and execute a folding instruction; a power supply unit is electrically connected to the driving member, the distance sensor and the processor.

Further, the retractable awning body is provided with a light sensor, the light sensor signal is connected to the processor, and the light sensor senses the intensity of light to generate a strong light signal or a weak light signal, and the processing After receiving the strong light signal, the processor controls the driving member to drive the retractable awning body to execute the unfolding instruction, or after receiving the weak light signal, the processor controls the driving member to drive the retractable awning body to execute the folding instruction. Instructions, where the collapse instruction takes precedence over the expansion instruction.

Furthermore, the retractable awning body is provided with at least one light-emitting element. The signal of the light-emitting element is connected to the processor. When the processor receives the strong light signal, the light-emitting element will be turned off. If the processor receives the weak light signal, the light-emitting element will be turned off. , then the above-mentioned light-emitting element is activated.

Further, the retractable awning body is provided with a humidity sensor, the humidity sensor signal is connected to the processor, and the humidity sensor senses the humidity in the air to generate a humidity signal or a dry signal, and the processing After receiving the moisture signal, the processor controls the driving member to drive the retractable awning body to execute the unfolding instruction, or after receiving the dry signal, the processor controls the driving member to drive the retractable awning body to execute the folding instruction. Among them, the collapsing instruction takes precedence over the unfolding instruction.

Wherein, the retractable awning body includes the rotating shaft, a supporting unit and a shielding member. The rotating shaft is located at the fixed end and is provided on a bearing member. The supporting unit includes a first supporting member, a second supporting member, a A third support member, a fourth support member and a support rod are located at the movable end, and one end of the first support member and one end of the second support member are pivotally connected to each other through a first elastic member.
