Abstract

The utility model relates to a solar electronic watch, which belongs to an electronic watch. An electronic watch body power supply comprises a semiconductor arranged on the surface of the electronic watch body. A photovoltaic cell module is formed by connecting four silicon photovoltaic cell modules in series, wherein, the length and the width of each silicon sheet are 2.5 mm and 2.5 mm. Because of the utilization of the solar energy, the utility model has the advantage of long cell replacement period.

Description

Solar electronic watch

The utility model relates to electronic watch, particularly a kind of electronic watch with solar cell.

Electronic watch, especially quartz watch because it has advantages such as when walking is accurate, more and more are subjected to people's favor.But, for guaranteeing the normal operation of electronic watch, need change battery termly, this just brings many inconvenience to the user.Therefore, how prolonging electronic watch replacing battery has the cycle, is that a problem to be solved is arranged at present.

The purpose of this utility model is to provide a kind of solar-electricity sublist, energy when it utilizes solar cell as electronic watch illumination to be arranged, thus guaranteed the long-term use of battery in the electronic watch.

Above-mentioned purpose of the present utility model is achieved in that a kind of solar-electricity sublist, comprises an electronic watch body, and its design feature is that the power supply of this electronic watch body comprises the optical semiconductor battery plate that is arranged on the electronic watch surface.Described photovoltaic cell module is to be in series by four silicon photocell plates, and wherein the length and width of every silicon plate is of a size of 2.5 * 2.5 millimeters.

Provide embodiment of the present utility model below in conjunction with accompanying drawing, and be described in further detail.

Fig. 1 is an electronic watch structural representation of the present utility model.

Fig. 2 is a solar-electricity sublist fundamental diagram of the present utility model.

With reference to Fig. 1, the utility model solar-electricity sublist comprises an electronic watch body 1, is provided with a photovoltaic cell module 2 on its surface.This photovoltaic cell module is to adopt silicon sheet material, and at this moment, in view of the voltage of every silicon chip solar cell is about about 0.4 volt, the electric current that it produced then is directly proportional with its area.Therefore, for satisfying the requirement of electronic watch power supply, the utility model photovoltaic cell module 2 adopts 4 silicon chip serial connections to form, and wherein the length and width of each silicon chip are of a size of 2.5 * 2.5 millimeters.Obviously, except above-mentioned silicon materials, the solar cell that also can adopt other semiconductor materials to constitute.

It is the electronic watch principle of work of power supply with the solar cell that Fig. 2 has drawn.As shown in the figure, under sunshine, photovoltaic cell module 2 produces electric currents, with it and the capacitor C two ends that connect form operating voltage, drive circuit 3 in the electronic watch with this, and drive the stepper motor 4 of electronic watch inside, so the control wrist-watch the time, minute, second the pin timing.Because the life-span of solar cell is longer, as long as and have illumination just can work, therefore, when battery was used in it and the electronic watch, no matter use was daytime, still the night of unglazed photograph, electronic watch all runs well, simultaneously, because battery only just starts work in the electronic watch when unglazed the photograph, this has just prolonged the time of its use widely.What is particularly worth mentioning is that, when with the electronic watch of solar cell adapted in battery when having chargeable performance, then has more tangible advantage, this is because the unnecessary electric energy that is produced by solar cell when illumination is arranged can also be to battery charge in the electronic watch, thereby can keep its use over a long time.In addition, because electronic watch body of the present utility model can be various types of accutrones, comprise the rather well received accutron with magnetic health care at present, therefore, it has more wide practical value.

Claims

1, a kind of solar-electricity sublist, comprise an electronic watch body (1), the stepper motor (4) that is provided with circuit (3) in the electronic watch in it and drives the indicator running is characterized in that this electronic watch body (1) power supply comprises to be arranged on this lip-deep semiconductor photovoltaic cell module of electronic watch body (1) (2).

2, solar-electricity sublist according to claim 1 is characterized in that, this photovoltaic cell module (2) is to be in series by four silicon photocell plates, and wherein, the length and width of every silicon chip are of a size of 2.5 * 2.5 millimeters.
