Abstract
The utility model provides a solar light-sensing rechargeable clock. The solar light-sensing rechargeable clock comprises a clock body, a solar charging panel, a storage battery and a charging switching circuit, wherein the solar charging panel and the storage battery are electrically connected with the charging switching circuit respectively, and the charging switching circuit is electrically connected with a control circuit board of the clock body. After the solar charging panel converts solar energy into electric energy, the electric energy is transmitted to the storage battery or the control circuit board of the clock body through the charging switching circuit so that the storage battery or the control circuit board can control the operation of the clock. The charging switching circuit is provided with a power supply selector switch, a brightness sensor and a voltage stabilizing circuit, and the brightness sensor selects the storage battery or the solar charging panel according to the outside brightness to directly supply power to the clock body. The solar clock not only can operate by means of the built-in storage battery, but also can generate power to operate by the utilization of solar energy, does not consume convectional electric energy and is a green and environment-friendly article for use.
Description
Technical field
The present invention relates to a kind of Application of Solar Energy field, refer in particular to a kind of sun power light sensation charging clock.
Background technology
Existing clock mostly is normal power supplies such as adopting disposable battery or rechargeable battery and powers, clock is the daily necessities that work long hours, normal power supplies needs often to change, can not energy-conserving and environment-protective, if can not in time change power supply, can cause the problem of clock suspension, affect people's live and work.
Therefore, demand providing a kind of portable clock that can utilize sustainable energy urgently, can be for clock for a long time.
Summary of the invention
A kind of sun power light sensation charging of the utility model clock, comprise clock main body, solar recharging panel, accumulator and charging conversion circuit, solar recharging panel and accumulator are electrically connected with charging conversion circuit respectively, charging conversion circuit is electrically connected with the control circuit board of clock main body, the running of control clock.
Preferably, after described solar recharging panel was converted to electric energy with sun power, the control circuit board that is sent to accumulator or clock main body through charging conversion circuit made it control the running of clock.
Preferably, described charging conversion circuit is provided with power change-over switch, luminance sensor and mu balanced circuit, and luminance sensor is selected directly to be powered to the clock main body by accumulator or solar recharging panel according to extraneous brightness.
Preferably, described accumulator is lithium battery.
Compared with prior art, the utility model sun power clock setting has the multiple power sources power supply, comprises solar cell and accumulator, when light is stronger, solar cell is powered to it, and to the accumulator accumulation of energy of charging, when photoelectricity is weak, adopt accumulator to power, like this, the sun power clock can utilize the internal battery operation, also can utilize sun power to come generator operation, it does not consume conventional electric energy, is environment-protecting articles.
Description of drawings
Fig. 1 is the structural representation of the utility model sun power clock;
Fig. 2 is the system chart of the utility model sun power clock;
Fig. 3 is the circuit block diagram of the charging conversion circuit of the utility model sun power clock.
Embodiment
Shown in seeing figures.1.and.2, the utility model sun power clock comprises clock main body 1, solar cell 2, charging conversion circuit 3 and accumulator 4, wherein, be built-in with control circuit board 10 in the described clock main body 1, solar cell 2 is electrically connected with charging conversion circuit 3, and the control circuit board 10 in charging conversion circuit 3 and the clock main body 1 is electrically connected, after solar cell 2 is converted to electric energy with sun power, be sent to the control circuit board 10 of clock main body 1 through charging conversion circuit 3, make the running of its control clock.Described accumulator 4 is electrically connected between the control circuit board 10 and charging conversion circuit 3 of clock main body, when sunny, solar cell 1 can charge to accumulator 4 by charging conversion circuit 3, so that the sun power clock light a little less than, such as night or when overcast and rainy, also can luminous lighting or displaying, described accumulator 4 is lithium battery.
With reference to shown in Figure 3, described charging conversion circuit 3 is provided with luminance sensor 30, power change-over switch 32 and mu balanced circuit 34, when luminance sensor 30 detects extraneous brightness and is higher than setting value, power change-over switch 32 is connected solar cell 2, is adjusted to suitable voltage by solar cell 2 through mu balanced circuit 34 and powers to control circuit board 10; When the brightness that detects the external world was lower than setting value, power change-over switch 32 was connected accumulators 4, was adjusted to suitable voltage by accumulator 4 through mu balanced circuit 34 and powered to control circuit board 10.
Described sun power clock is provided with two kinds of powering modes, solar cell and accumulator, under well-lighted condition, by solar cell the control circuit board of clock is powered, and accumulator 4 is charged, it can be powered to control circuit board under the weak condition of light, like this, so that the sun power clock is in the situation that need external power supply, control circuit board can be kept the operation of clock when channel status.
It is worthy of note; protection domain of the present utility model is not limited to above-mentioned instantiation mode; according to basic fundamental of the present utility model design, also can essentially identical structure driven, the layout of structure adjusted all to belong to originally be the protection domain of utility model.
