Abstract
The utility model belongs to the technical field of flashlights, relates to a flashlight displaying electric quantity by striking and in particular to the flashlight with an electric quantity display function. The flashlight displaying the electric quantity by striking comprises a flashlight body and an electric quantity displayer arranged on a surface of the flashlight body and is characterized in that the electric quantity displayer contacts a single board computer micro control unit (MCU) used for controlling the electric quantity display and an integrated circuit plate of an electric quantity detection circuit used for detecting the electric quantity of a battery of the flashlight through an elastic sensor. An electric quantity display circuit is further in parallel connection on the MCU and the detection circuit. The flashlight displaying the electric quantity by striking is simple in structure, capable of achieving rapid display after the electric quantity is detected and rapidly extinguishing the displayer and capable of effectively saving electric quantity of the battery. The flashlight can rapidly display current electric quantity again just after the flashlight is struck and then the displayer is extinguished. The flashlight displaying the electric quantity by striking can display the current electric quantity and have a low voltage warning function. When the voltage of the battery is lower than a warning value, a red light is automatically lightened and the lighting condition is maintained continuously.
Description
Technical field:
The utility model relates to a kind of flashlight that shows electric weight that clashes into, and it belongs to the flashlight technical field, particularly has the flashlight of electric quantity display function.
Background technology:
Flashlight in use often can run into the situation that battery does not have electricity.Traditional flashlight is not because there is the Presentation Function of the dump energy of battery, thus the user just can't understand in advance flashlight can also be how long luminous.The electric weight of tradition flashlight shows
In order to address the above problem, so that the user has clear and definite understanding to the electric weight of flashlight, can effectively grasp the Use Limitation of flashlight, a class solution has been proposed in the prior art, namely adopt Light-Emitting Diode to show.Under this class technical scheme, being used for the light emitting diode that electric weight shows can light always, continues shinny the time, and the also electric weight of consuming cells has increased the power consumption of flashlight.
Summary of the invention:
The purpose of this utility model is to provide a kind of little power consumption, shows in time and utilize to clash into the flashlight that the bump that can show electric weight moment shows electric weight.
The purpose of this utility model is achieved in that
A kind of flashlight that shows electric weight that clashes into, it comprises the flashlight body, be arranged on the electric-quantity display device of flashlight body surface, it is characterized in that described electric-quantity display device by elasticity sensor with contact for the single board computer MCU of control display electric weight and for detection of the surface-mounted integrated circuit of the electric quantity detecting circuit of flash-light battery electric weight; At described MCU and testing circuit electric quantity display circuit also in parallel.
Described elasticity sensor is spring sensor.
The utility model is simple in structure, can realize detecting showing rapidly behind the electric weight and extinguishing rapidly, has effectively saved the electric weight of battery, only needs bump hand torch just can again show rapidly current electric quantity again, extinguishes immediately again.Can show current electric quantity, the utility model can also have the low-voltage alarm function, and red light can automatically light and continue always and light when cell voltage is lower than warning value.
Description of drawings:
Fig. 1 is structural representation of the present utility model
Fig. 2 is schematic block circuit diagram of the present utility model
The specific embodiment:
Below in conjunction with Fig. 1 and Fig. 2 the utility model is further detailed:
It comprises flashlight body 1 the utility model, and described flashlight body 1 is prior art, and it has comprised the bulb 4 of flashlight, the switch of battery 5 and flashlight etc.In order to realize the demonstration of battery electric quantity, at the flashlight body surface electric-quantity display device 2 is set, also there has been the flashlight with electric quantity indicator in the prior art.
In order to realize the purpose of this utility model, described electric-quantity display device by an elasticity sensor 3 with contact for the single board computer MCU of control display electric weight and for detection of the surface-mounted integrated circuit 6 of the electric quantity detecting circuit of flash-light battery electric weight; At described MCU and testing circuit electric quantity display circuit also in parallel.In the present embodiment, described elasticity sensor 3 is spring sensor, utilizes elasticity sensor 3 to realize that the utility model bump shows the purpose of electric weight.
Operation principle of the present utility model is as follows:
As shown in Fig. 2 schematic block circuit diagram, when using flashlight, closed electrical source switch S battery begins power supply, MCU and testing circuit detected current battery electric quantity when illuminator was luminous, and the control electric quantity display circuit shows corresponding electric weight, extinguished by MCU and testing circuit control after showing several seconds.
When torch is in the use state, check battery electric quantity, make spring sensor SD vibration by knocking torch, spring sensor SD in the conducting of when vibration to single-chip microprocessor MCU and signal of testing circuit, MCU and testing circuit detect current battery electric quantity, and the control electric quantity display circuit shows corresponding electric weight, extinguished by MCU and testing circuit control after showing several seconds.
In the use procedure of torch, MCU and testing circuit are detecting battery electric quantity all the time, and when MCU and testing circuit detected battery electric quantity and be lower than warning value, the red light on the control electric quantity display circuit automatically lights and continues always to be lighted.
Related single board computer MCU and testing circuit and electric quantity display circuit all adopt prior art to get final product in the utility model.
