Photovoltaic Smart Bracelet

Abstract

The invention provides a photovoltaic smart wristband, which includes a base, the middle section of which is a transparent sealed tube, and a cylindrical inner core connected to the base through a rotating shaft is arranged inside; a photovoltaic panel is formed on half of the inner core surface, and the other There is a display screen on half of the peripheral surface; the two ends of the rotating shaft extend into the vertical slideway in the base respectively, and the two ends of the rotating shaft are respectively connected to a gear, and the gear meshes with a rack that can slide up and down in the slideway; the rack The upper and lower ends of the photovoltaic panel are constrained by restraint springs. When the base is stationary and facing up, the rack, gear, and rotating shaft are balanced at the position where the photovoltaic panel is facing up; the rack obtains 1m / s 2 The force required by the acceleration can make the rack overcome the elastic force of the constraint spring and slide to the limit position at the lower end of the slideway; when the rack is at the limit position at the lower end of the slideway, the gear rotates to the position where the display screen faces upward. The smart bracelet can make full use of solar energy to charge its battery, thereby eliminating or reducing the trouble of charging.

Description

Technical field [0001] The present invention relates to the field of smart wearable devices, in particular, a smart bracelet. Background technique [0002] The smart bracelet is a relatively popular smart wearable device, which is worn on the wrist for easy checking of time and body movement status. Because there are many internal sensors in the smart bracelet, and it usually maintains real-time communication with the mobile phone through the Bluetooth module, the battery life is short. Generally, it needs to be charged once a day or two, which obviously brings greater inconvenience to the user . Summary of the invention [0003] In view of the above-mentioned problems, the purpose of the present invention is to provide a photovoltaic smart bracelet, which can fully utilize solar energy to charge its battery, thereby avoiding or reducing the trouble of charging. [0004] The technical solution adopted by the present invention to achieve the technical purpose is: the photovoltaic s...
