Abstract
The invention provides a low-voltage prompting method of an intelligent key. The low-voltage prompting method comprises the steps of providing a built-in battery, a voltage detecting circuit, a low-voltage prompting unit and a charging circuit, wherein the voltage detecting circuit and the charging circuit are respectively and electrically connected with the built-in battery, and the low-voltage prompting unit is electrically connected with the voltage detecting circuit; and giving sound or sending a photo-electrical prompt through the low-voltage prompting unit when the voltage detecting circuit detects that voltage of the built-in battery is lower than a preset value. Compared with the prior art, when the voltage of the built-in battery is lower than the preset value, the low-voltage prompting method of the intelligent key sends the corresponding prompt through the low-voltage prompting unit, accordingly the battery can be replaced or is timely charged when the intelligent key is inserted into an automobile starting system, and the convenience in use is improved.
Description
Technical field
The present invention relates to a kind of low-voltage reminding method of the Intelligent key for automobile.
Background technology
At present, automobile is widely used in various occasions, and especially kart is more and more universal in popular life.Intelligent key is being brought into play important effect as a kind of important accessory of automobile aspect convenience.Usually all be built-in with battery in the Intelligent key, along with the increase of service time, the voltage in the battery can reduce gradually, if forget for a long time and change battery or charging, may cause Intelligent key can not be used for starting automobile, brings the inconvenience in the use.
Summary of the invention
The technical matters that the present invention mainly solves is that the low-voltage of existing Intelligent key can not get reminding.
In order to solve the problems of the technologies described above, the embodiment of the invention discloses a kind of low-voltage reminding method of Intelligent key, comprising:
Internal battery, voltage detecting circuit, low-voltage Tip element and charging circuit are provided, and described voltage detecting circuit and described charging circuit electrically connect with described internal battery respectively, and described low-voltage Tip element and described voltage detecting electrically connect;
After voltage that described voltage detecting circuit detects described internal battery was lower than preset value, described low-voltage Tip element was sounded or the photoelectricity prompting.
In a preferred embodiment of the present invention, the normal working voltage of described internal battery is 3.0 volts.
In a preferred embodiment of the present invention, the voltage that detects described internal battery when described voltage detecting circuit is lower than preset value, and after Intelligent key inserted the start-up system of automobile, described charging circuit charged to described internal battery by the power supply in the automobile.
In a preferred embodiment of the present invention, the power supply in described charging circuit and the automobile electrically connects.
In a preferred embodiment of the present invention, described low-voltage Tip element comprises loudspeaker and LED.
Compared to prior art, the low-voltage reminding method of described Intelligent key of the present invention is when the voltage of internal battery is lower than preset value, send corresponding prompting by the low-voltage Tip element, thereby can change battery, or Intelligent key in time charges when inserting the start-up system of automobile, promotes ease of use.
Description of drawings
In order to be illustrated more clearly in the technical scheme in the embodiment of the invention, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the framed structure synoptic diagram of low-voltage reminding method one preferred embodiment of Intelligent key of the present invention.
Embodiment
To the technical scheme in the embodiment of the invention be clearly and completely described below, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making all other embodiment that obtain under the creative work prerequisite.
The embodiment of the invention discloses a kind of low-voltage reminding method of Intelligent key, see also Fig. 1, described low-voltage reminding method comprises:
Internal battery 1, voltage detecting circuit 2, low-voltage Tip element 3 and charging circuit 4 are provided, described voltage detecting circuit 2 and described charging circuit 4 electrically connect with described internal battery 1 respectively, and described low-voltage Tip element 3 electrically connects with described voltage detecting circuit 2;
After voltage that described voltage detecting circuit 2 detects described internal battery 1 was lower than preset value, described low-voltage Tip element 3 was sounded or the photoelectricity prompting.
Wherein, the normal working voltage of described internal battery 1 is 3.0 volts, and when being lower than this voltage, described Intelligent key may not operate as normal.Described low-voltage Tip element 3 comprises that loudspeaker (not shown) and LED(figure do not show).
After voltage that described voltage detecting circuit 2 detects described internal battery 1 was lower than preset value, the loudspeaker of described low-voltage Tip element 3 were sounded or are sent the photoelectricity prompting by LED.
Power supply in described charging circuit 4 and the automobile electrically connects, the voltage that detects described internal battery 1 when described voltage detecting circuit 2 is lower than preset value, and after Intelligent key inserted the start-up system of automobile, described charging circuit 4 charged to described internal battery 1 by the power supply in the automobile.
Compared to prior art, the low-voltage reminding method of described Intelligent key of the present invention is when the voltage of internal battery is lower than preset value, send corresponding prompting by the low-voltage Tip element, thereby can change battery, or Intelligent key in time charges when inserting the start-up system of automobile, promotes ease of use.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present invention.
