Description
Technical field
This utility model belongs to electronic instrumentation, especially relates to a kind of miniature instrument of refreshing oneself of prompting of driving for fatigue.
Background technology
Drive over a long distance or afternoon process easily occurs fatigue symptom, common method of refreshing oneself is listened to the music exactly, has tea, and pats the means of oneself specific part, but its objective effect is all more limited.The technology application of prior art in driving is tired is focused mostly on and to monitor in real time in fatigue and to be caused the attention of human pilot by sound and light alarm; In addition, also have the means of being undertaken stimulating by output high level voltage to apply, but this method have very large danger coefficient.Therefore, the general effect of prior art is undesirable, although sound and light alarm has certain stimulating effect, along with people is to the adaptability of sound, thisly refreshes oneself effect worse and worse; The rest that sound and light alarm affects Che Neifei human pilot adopts voltage export easily because the contact impedance of contact site is unfixing and produce the exciting current varied in size.Due to the skin of people under different states such as: perspire, skin surface have water or dry skin contact impedance is widely different, therefore can because the difference of contact impedance produces widely different electric current after high pressure joins corresponding site, people is easily allowed to produce electric shock feeling, too little cannot reach stimulation and to refresh oneself effect, thus affect it and normally use.
Utility model content
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of miniature instrument of refreshing oneself safe and effective, easy to use.
To achieve these goals, the technical scheme that adopts of this utility model is as follows:
A kind of miniature instrument of refreshing oneself, comprise insulation crust, electric power management circuit, constant current source generating circuit and excitation output circuit, wherein said insulation crust holds described electric power management circuit, constant current source generating circuit and excitation output circuit, described electric power management circuit is connected with described constant current source generating circuit, described constant current source generating circuit is connected with described excitation output circuit, the external two or more excitation output interface of described excitation output circuit.
Preferential, also comprise user interactions interface, described user interactions interface is respectively with electric power management circuit, constant current source generating circuit with encourage output circuit to be electrically connected.
Further, described user interactions interface is installed on the upper surface of described insulation crust.
Further, described user interactions interface be for adjust output amplitude or and the button of power supply opening and closing.
Preferential, also comprise LED warning light, described LED warning light is arranged at the side surface of described insulation crust.
Preferential, also comprise the pendant ring be connected with described insulation crust.
Preferential, described insulation crust longitudinal section is circle, rectangle, cylindrical or trapezoidal.
Adopt after said structure, this utility model compared to the prior art advantageously: technical scheme described in the utility model is neural mainly through direct physical electricity irritation hand, enlivens nervus centralis, makes brain keep clear-headed; Constant-current source exports, and electric current exports constant, can not produce different effect of stimulation because of the difference of contact site contact impedance; Thus design one safely and effectively physics to refresh oneself equipment, can install on the steering wheel easily, can grasp or the electrode of refreshing oneself of touch apparatus if feel tired out in driving conditions, can effectively refresh oneself.

Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
As shown in Figure 1 to Figure 3, this utility model embodiment provides a kind of miniature instrument of refreshing oneself, and comprises insulation crust 1, electric power management circuit 3, constant current source generating circuit 4 and excitation output circuit 5.
Described insulation crust 1 holds described electric power management circuit 3, constant current source generating circuit 4 and excitation output circuit 5, the instrument internal circuit that can ensure to refresh oneself does not produce with the metallic member of automobile and contact, while be also convenient to installation and the structure of being affiliated on the steering wheel or wrist-watch etc.Described electric power management circuit 3 is connected with described constant current source generating circuit 4, and described constant current source generating circuit 4 is connected with described excitation output circuit 5, the external two or more excitation output interface 6 of described excitation output circuit 5.In the present embodiment, described excitation output interface 6 can be electrode.Described electric power management circuit 3 is powered for each circuit, is battery powered in the present embodiment.In addition, constant current source generating circuit 4 voltage/current excitation signal, is actuated to the sine wave or square wave that are no more than 100hz-5kHz, and signal code amplitude is fixed or adjustable, but all within the scope of human-body safety.In the present embodiment, described insulation crust 1 longitudinal section is cylindrical, in addition can also be circular, rectangle or trapezoidal.
Use according to oneself demand for the ease of user, in this utility model one embodiment, this instrument of refreshing oneself also comprises user interactions interface 2, and described user interactions interface 2 is respectively with electric power management circuit 3, constant current source generating circuit 4 with encourage output circuit 5 to be electrically connected.
Therefore, user interactions interface 2 can consider two types: one, without button operation, and fixed signal exports, and the normal time is low consumes operation altogether, possesses status information instruction; Two, there is button operation, can output amplitude be adjusted, and can switching on and shutting down, possess status information instruction.In this utility model one embodiment, described user interactions interface 2 is installed on the upper surface of described insulation crust 1, described user interactions interface 2 be for adjust output amplitude or and the button of power supply opening and closing.
In this utility model one embodiment, this instrument of refreshing oneself also comprises LED warning light 7, and described LED warning light 7 is arranged at the side surface of described insulation crust 1.
In this utility model one embodiment, this instrument of refreshing oneself also comprises the pendant ring 8 be connected with described insulation crust 1.The form of this instrument of refreshing oneself for wrist-watch, pendant or can be nested on steering wheel.
Therefore, instrument of refreshing oneself described in this utility model embodiment has plural excitation output interface, can be exported one or more according to the position of excitation output interface to stimulate, stimulate output amplitude within human-body safety scope, and the size that can be exported by user interactions interface adjustment excitation.Can by hands thigmic stimulus output interface when human pilot is felt tired out, stimulate to obtain voltage/current at the regional area of excitation output interface, this stimulus signal reaches brain centres nerve by neurotransmission, enliven central nervous system, thus allow brain keep clear-headed, reach the object of refreshing oneself.
Foregoing is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
