Abstract

The utility model belongs to a time measuring instrument class, particularly an electric machinery accutron. In the utility model, a through hole is arranged on the traditional quartz accutron dial plate (2), and a solar battery (1) is fixed on the quartz accutron dial plate. Two poles of the solar battery can be connected in parallel in the power supply circuit of the quartz accutron, and both ends of the circuit and a power accumulator (4) can be connected in parallel to ensure that the accutron can normally work under the condition of no light irradiation. One end of the solar battery and a diode (5) which can prevent the power accumulator do reverse discharge for the solar battery are connected in series. The utility model is suitable for the users in village or remote regions particularly.

Description

Solar analog-type quartz accutron

The utility model belongs to the time keeping instrument class, specifically a kind of motor machine wrist-watch.

In recent years, the quartz watch of putting on market in a large number with punctual timing, advantage such as easy to use, was subjected to consumers in general's welcome deeply.But general use of this quartz watch that makes product at present just needs to change one-shot battery more than a year, therefore gives vast rural area and other long-term works or lives in backwoodsman user and bring great inconvenience.Moreover the selected battery of quartz watch of each wrist-watch manufacturer production of the whole nation also is various, is difficult to exchange.Even bought the battery that to change.Also of common occurrence because of changing the battery-operated situation that causes movement to damage accidentally.

The purpose of this utility model is in order to overcome above-mentioned deficiency, and a kind of sun power indicating quartz electronic wristwatch that utilizes luminous energy to keep the long-term normal operation of quartz watch of design.

The utility model is achieved in that opens a through hole on the dial plate of traditional crystal-oscillator watch, solar cell is fixedly mounted on the dial plate of crystal-oscillator watch.Solar cell is connected in parallel in the feed circuit of crystal-oscillator watch, for the electric energy that solar cell is produced stores, so that under the environment of no sunshine, keep quartz watch normally to move, accumulator in parallel in the current supply circuit of solar cell.For prevent unglazed according to the time electric energy in the accumulator to the solar cell back discharge, at diode of end series connection of solar cell.In order to prevent that solar cell is under strong illumination; overvoltage that produces or big electric current cause damage to the electronic component in accumulator or the quartz watch circuit; resistance of series connection and voltage-limiting protector in parallel in the current supply circuit of solar cell have so just constituted the feed circuit of sun power pointer quartz electronic watch described in the utility model.Its principle of work is: having under the situation of solar light irradiation, be installed in the electric energy that solar cell produced on the dial plate and supply with quartz watch on the one hand and make it normal operation, charging on the other hand accumulator in parallel.When no solar light irradiation, then there is accumulator to provide electric energy that quartz watch is normally moved.

Because this solar energy quartz electronic watch can utilize luminous energy to give movement interior charging accumulator, thereby has eliminated vast rural area and work or lived in the trouble that backwoodsman consumer changes battery, this wrist-watch is specially adapted to the personnel in outside work or work.

The circuit of Fig. 3 is suitable for the scheme of Fig. 2, and the circuit of Fig. 4 is suitable for the scheme of Fig. 1.

Below in conjunction with accompanying drawing the utility model is described in detail: the utility model comprises watchcase (3), dial plate (2), the quartz watch control circuit (8) that constitutes the conventional quartz electronic watch, its technical essential is to open a through hole on dial plate (2), and solar cell (1) is fixedly mounted on the dial plate (2).Employed solar cell can be that monocrystalline silicon also can be amorphous silicon.If solar cell (1) is the sheet metal base, preferably it is manufactured fan-shapedly, make that fan-shaped solar cell (1) tandem compound becomes annular more than four or four, be fixedly mounted on then on the dial plate (2), as shown in Figure 1, the through hole of at this moment opening on dial plate (2) is a circular hole.If solar cell (1) is a glass substrate, preferably it is manufactured the rectangle that constitutes by the series connection of the rectangle more than 1, it is installed on the dial plate (2), as shown in Figure 2, at this moment the through hole of opening on dial plate (2) is a slot.The two poles of the earth of solar cell (1) are connected in the feed circuit of quartz watch control circuit (8).Because solar cell (1) can only be accepted luminous energy by day, for this quartz watch can normally be moved under the situation of no rayed, at the current supply circuit two ends of solar cell (a 1) accumulator (4) in parallel, accumulator (4) can be a secondary cell, as shown in Figure 4.Accumulator (4) also can be a capacitor.As shown in Figure 3, in order to prevent that under the situation of no rayed accumulator (4) increases the loss of electric energy in the accumulator (4) to solar cell (1) discharge.Connect an isolating diode (5) in order to prevent under the irradiation of solar cell (1) at high light at an end of solar cell (1); produce too high voltage or excessive electric current; electronic component in accumulator (4) and the quartz watch control circuit is damaged; an end of solar cell (a 1) series connection current-limiting resistance (6) and in the current supply circuit of solar cell (1) voltage-limiting protector (7) in parallel; protector (7) can be a voltage stabilizing diode; as shown in Figure 4, also voltage stabilizing integrated component.Protector (7) is connected in parallel on the two ends of accumulator (4).Through the current limliting of resistance (6) and the voltage-limiting protection of protector (7), can avoid accumulator to overcharge the generation of phenomenon effectively, and work in the voltage range that quartz watch is being stipulated always like this.
