Abstract
The utility model provides a low voltage prompting system for an intelligent key, which comprises 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 electrically connected with the built-in battery; the low voltage prompting unit is electrically connected with the voltage detecting circuit. Compared with the prior art, the low voltage prompting system for the intelligent key disclosed by the utility model can send out corresponding prompts by the low voltage prompting unit when the voltage of the built-in battery is lower than a pre-set value, so that the battery is replaced, or the intelligent key is inserted into a starting system of a car for charging timely, and the use convenience can be promoted.
Description
Technical field
The utility model relates to a kind of low-voltage prompt system that is applied to Intelligent key.
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.
The utility model content
The technical matters that the utility model 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 utility model embodiment discloses a kind of low-voltage prompt system of Intelligent key, described low-voltage prompt system comprises internal battery, voltage detecting circuit, low-voltage Tip element and charging circuit, 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 circuit electrically connect.
In a preferred embodiment of the present utility model, the normal working voltage of described internal battery is 3.0 volts.
In a preferred embodiment of the present utility model, the power supply in described charging circuit and the automobile electrically connects.
In a preferred embodiment of the present utility model, described low-voltage Tip element comprises loudspeaker and LED.
Compared to prior art, the low-voltage prompt system of described Intelligent key of the present utility model 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 among the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, 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 prompt system one preferred embodiment of the utility model Intelligent key.
Embodiment
To the technical scheme among the utility model embodiment be clearly and completely described below, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtain under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment discloses a kind of low-voltage prompt system of Intelligent key, see also Fig. 1, described low-voltage prompt system comprises internal battery 1, voltage detecting circuit 2, low-voltage Tip element 3 and charging circuit 4, 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.
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 prompt system of described Intelligent key of the present utility model 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 embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model description 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 utility model.
