Description

An automatic steering umbrella

technical field

The invention relates to an umbrella, in particular to an automatic steering umbrella.

Background technique

Umbrellas are necessities of life. In order to deal with rainy weather, people need to go out with umbrellas. Umbrellas are widely used in a wide range of applications. Outdoor restaurants need to place large umbrellas, and stall owners in markets sometimes need umbrellas to cope with the weather. Yet the change of wind direction has driven the change of rain direction, often makes people be at a loss, also makes the function of keeping out the rain of umbrella greatly reduced, especially in unoccupied place. At present, the umbrella varieties on the market are relatively single, and the functions are also very basic, which cannot meet people's needs to a certain extent.

Contents of the invention

The technical problem to be solved by the present invention is to provide an automatic steering umbrella with humanized functions and convenient use. In order to achieve the above object, the technical solution of the present invention is an automatic steering umbrella, which includes an umbrella handle, an umbrella pole and an umbrella surface fixed on the umbrella pole, and also includes an encoder, a chip, a motor, a battery and a switch; The top of the umbrella pole is connected with the chip; the chip is also connected with a motor, a battery and a switch; the output shaft of the motor is connected with the umbrella pole; the motor, the chip and the battery are installed in the umbrella handle; a switch is arranged on the umbrella handle.

The umbrella pole is divided into two sections, and there is an included angle of 20-30° between the two sections of umbrella poles.

It is better that the lengths of the two sections of umbrella poles are equal, and the two sections of umbrella poles are combined together by threads.

The encoder is a single-turn absolute encoder with a wind vane fixed on its top.

The wind vane has two parts: a weather vane and a rotating rod. The weather vane part is made of hard material and can drive the rotating rod to rotate.

The single-turn absolute encoder is connected to the chip through the wire in the umbrella pole.

The chip is mainly composed of a 51 series single-chip microcomputer, a stepping motor drive chip and a voltage stabilizing circuit.

The motor is a four-phase hybrid stepping motor.

The batteries are four 1.5V dry battery packs.

The beneficial effect of the present invention is: ①The two sections of umbrella poles are combined together through threads, and they can be separated by dismantling the threads, which is convenient for storage. ②Compared with the traditional umbrella, the encoder, chip and motor are added, which can automatically adjust the orientation of the umbrella surface according to the wind direction, and can solve the problem caused by the change of the wind direction when it rains. ③The application objects and application occasions are wider, and it is more advantageous in unmanned places. Humanized function, simple operation and reasonable design.
