Description
Technical field
The utility model relates to automobile key, in particular to a kind of chargeable, luminous automobile key.
Background technique
With the development of the times, automobile also develops from " the essential vehicles " to " diversification ".With economy
Development, automobile become a member in city, but since (vehicle removes outside headlight the limitation of car lighting at present, and also nothing is used for
Large-scale headlamp).Night can not carry out simple make an inspection tour to vehicle appearance and tire when picking up the car and confirm vehicle-state, in the process
It can not confirm for the electricity of car key and frequently result in key without electricity.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of car key, which, which is capable of providing, fills
Electricity, illumination, provide illumination when conveniently picking up the car at night.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of car key, including key shell, institute
It states and rechargeable battery, charging circuit board is set in key shell, USB charging interface, the USB are set on the key shell
Charging interface is connect with charging circuit board, and the charging circuit board is connect with rechargeable battery, the power supply of the rechargeable battery
Output end is connect by control switch with LED light, and the LED lamp is arranged on key shell.
The control switch is button-type mechanical switch.
Battery management system is set in the key shell, and the battery management system is connect with battery capacity indication lamp, institute
Battery capacity indication lamp is stated to be arranged on key shell.
The battery management system includes battery control unit and battery parameter acquisition unit, and the battery parameter acquisition is single
Member is connect, the battery control unit is used for basis for acquiring the remaining capacity of rechargeable battery with battery control unit
The battery dump energy control battery capacity indication lamp of acquisition shines.
The battery capacity indication lamp for issuing red light and green respectively.
The present invention has the advantages that by integrated LED lamp on the key, it is convenient can be with by LED lamp when picking up the car at night
It checks vehicle's surroundings, completes the vehicle inspection illumination before driving；Using rechargeable battery, cruising ability can be used continuously by force；
In order to reduce LED bring illumination kwh loss, information about power is indicated by red green indicator light, is powered by the USB of setting
Interface, easily passing through vehicle-mounted USB socket after vehicle start-up is key charging, conveniently supplements electricity at any time and energy is much of that
It is remaining to solve electricity.
Detailed description of the invention
Below to each width attached drawing of description of the invention expression content and figure in label be briefly described:
Fig. 1 is the utility model Key structure schematic diagram.
Specific embodiment
A specific embodiment of the invention is made further detailed below against attached drawing by the description to optimum embodiment
Thin explanation.
As shown in Figure 1, automobile key includes key shell, rechargeable battery, charging circuit board are set in key shell,
USB charging interface is set on key shell, USB charging interface is embedded on shell, for being connected to the inner and outer portion of key shell,
USBS charging interface is connect with the setting intracorporal charging circuit board of key shell, and charging circuit board is connect with rechargeable battery, can be filled
The power supply output end of battery is connect by control switch with LED light, and LED light is arranged on key shell, and set-up mode is
For preventing the slot of LED light on shell, the hole that setting is passed through for electric wire in slot, through hole is by the LED light and key in slot
The intracorporal rechargeable battery connection of spoon shell.
Control switch is arranged on shell, and by taking button switch as an example, button switch is arranged on shell, when button switch is pressed
After lower, electrical circuit is connected between rechargeable battery and LED light, and LED shines, and after putting down key switch, current supply circuit is disconnected,
LED light power-off is extinguished.
When in use, the power supply on-off control for LED light is realized by button switch, to control the bright of LED lamp
It goes out, thus convenient to use.Since LED light virtually increases the electric quantity consumption of the intracorporal battery of key shell, so setting can fill
Then battery is connect by the USB interface of setting with external charging equipment, the charging circuit board of centre setting includes pressure stabilizing electricity
Road, DC/DC circuit integration circuit board.Facilitate external equipment to connect by USB charging interface with rechargeable battery, is chargeable
Battery charging.
Due to using LED light, battery capacity can be consumed, there is the key of keyless access system for Intelligent key etc.
For, it is likely to result in cannot using for key, so must assure that the timely of key charging, due to being provided with USB charging
Mouthful, it may be convenient to it charges, it is now desired to recognize the remaining capacity information of rechargeable battery in time, whether recognize in time needs
It charges.It solves the problems, such as this, battery management system is set in key shell.
Battery management system includes battery control unit and battery parameter acquisition unit, and battery parameter acquisition unit is for adopting
The remaining capacity SOC for collecting rechargeable battery, connect with battery control unit, and battery control unit is used for the battery according to acquisition
Remaining capacity controls battery capacity indication lamp and shines.Battery parameter acquisition unit can realize voltage electricity for voltage, current acquisition unit
Stream acquisition conversion obtains SOC, and battery control unit is realized using 51 series monolithics.Battery capacity indication lamp is red for issuing respectively
Light and green comprising red LED, green LED.Red LED, green LED are arranged on key shell, for showing
Electricity is remaining, and when electricity abundance, battery control unit control issues green, when battery capacity deficiency, issues red.It provides in time
Charge reminder, to solve the consumption as using electricity caused by LED light.
One group of embedded rechargable power supplies module and LED light are installed in remote control key, are used for vehicle night failure
It can be illuminated etc. when checking problem, switch is opened when use, closed when not used.LED light but will than other headlamps
To be economical and practical, a LED bulb can be 5 to 10 years practical, and vehicle power supply and domestic power supply are available for charging, and holding can fill
The electricity of battery.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as using method concept and skill of the invention
The improvement for the various unsubstantialities that art scheme carries out, it is within the scope of the present invention.
