Description

Technical Field

[0001] This invention relates to the field of umbrella technology, and more particularly to a fully automatic umbrella. Background Technology

[0002] Umbrellas are a necessity in people's lives. Currently, the switch on umbrellas on the market is on the handle, but the switch on the umbrella of this invention is on the top of the umbrella shaft; a switch button is needed to open and close the umbrella, but the umbrella of this invention does not require a switch button. Summary of the Invention

[0003] A fully automatic umbrella includes a central umbrella rod (11), a retractable rod (12) on the upper part of the central umbrella rod (11) and an externally provided return spring (16), an umbrella canopy (13) at the upper end of the retractable rod (12), and a switch device inside the central umbrella rod (11). The switch device includes an angle sensor (1), a stepper motor (4), a coupling (5), a ball screw (6), a motor driver (3), a main control chip (2), a battery (15), a charging port (14), a sliding block (9), a partition (8), and a pull cord (10).

[0004] More preferably, the ball screw (6) and the central rod (11) are connected and fixed by balls (7).

[0005] More preferably, the sliding block (9) slides on the two partitions (8).

[0006] More preferably, the battery (15) is charged with a commercially available plug. Attached Figure Description

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0014] A fully automatic umbrella includes an umbrella rod (11), a retractable rod (12) on the upper part of the rod (11) and a return spring (16) on the outside, and an umbrella surface (13) on the upper end of the retractable rod (12). A switch device is provided in the upper part of the rod (11). In the switch device, a ball (7) connects the umbrella rod (11) and a ball screw (6), a pull line (10) is fixed on both sides of a sliding block (9) and connects the sliding block (9) and the retractable rod (12), the sliding block (9) in the ball screw (6) is connected to the umbrella pull line (10), a coupling (5) connects the ball screw (6) and a stepper motor (4), the stepper motor (4) is controlled by a motor driver (3) and an angle sensor (1) connected to a main control chip (2), and a battery (15) powers the device and charges it through a plug. According to the angle of the umbrella tilt, the angle sensor (1) transmits the signal to the main control chip (2). The main control chip (2) transmits the signal to the motor driver (3) to control the number of rotations of the stepper motor (4) and thus control the movement distance of the sliding block (9) on the ball screw (6). In this way, the umbrella can be opened and closed flexibly according to different postures, achieving the purpose of full automation.

[0015] In this embodiment, the term "angle sensor (1)" is a general term and does not represent any specific device. It includes angle switches, etc. Any device that controls the umbrella opening and closing by measuring angle is considered to infringe upon this patent.

[0016] When the umbrella is placed horizontally or with the canopy (13) facing down, the measured angle prevents the main control chip (2) from opening the umbrella; when the umbrella canopy (13) is facing up or tilted, the measured angle causes the main control chip (2) to control the pull cord (10) to move and open the umbrella. The reverse is also true.

[0017] The above description is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made in accordance with the scope of the present invention patent application, the structure, features and principles described herein are included within the scope of the present invention application.
