Background technology
At present, the walking-replacing tool such as electric motor car, automobile has been come in the family of vast ordinary people, and remote-control key makesAlso many with also more coming.Wireless remote controlled keys for automobile is the contactless electronic manipulation device for being turned on and off lock, and the device leads toCross and at least two operation buttons (typical arrangement is the button that unlocks and shut) are set on remote-control key surface, press with operationKey coordinates the wireless signal transmission circuit inside the remote-control key, this circuit be mostly using built-in button cell powered operation,When depresses button, circuit using radio wave unlocking or shutting the receiver of remote-control sytem that order is sent to lock, by receptorOrder is passed to automobile middle control mechanism, and then controls being turned on and off for lock.
Remote-control key must accomplish compact, suitably carry with and it is necessary to reliability and durability.Existing remote-control keyDisposable lithium battery or aneroid battery are used mostly as power supply, as the power consumption of remote-control key is less, batteries can be withMeet the use demand of several years.But, general key classification of waterproof is IP65, and even lower, after water inlet, key electricity is rapidExhaust；If the classification of waterproof of remote-control key is risen to IP67, although can ensure that the water resistance of key, but, in electricityWhen amount changes battery after normally exhausting, waterproof construction will be destroyed.In order to overcome the problems referred to above, the distant of rechargeable type is occurred in thatControl key, but, due to the presence of charging inlet, however it remains the problem of remote-control key waterlogged damage.
Utility model content
This utility model provides a kind of novel maintenance-free remote-control key, for solving remote-control key short life, needing to changeThe problem of battery.
In order to solve the above problems, this utility model provides a kind of novel maintenance-free remote-control key, including housing and settingMaster controller and lithium battery in the housing, the housing are provided with the operation button being connected with the master controller, the masterController is also associated with transmitting antenna, is additionally provided with the solar panel of the recessed housing, in the housing on the housingThe energy acquisition chip being connected with the solar panel is provided with, the energy acquisition chip is connected with the master controller,The solar panel is connected with super capacitor and the lithium battery respectively also by the energy acquisition chip, the lithium electricityPond is connected with the master controller by the energy acquisition chip.
The novel maintenance-free remote-control key that this utility model is provided also has following technical characteristic：
Further, the capacity of the super capacitor is 0.1F to 1F.
Further, the solar panel is the good non-crystalline silicon solar panel of the low light level.
Further, the lithium battery is chargeable lithium coin cells.
Further, the housing is resin-encapsulated housing, is provided with inner insulating layer in the housing, and the operation button isSilica gel button with the housing one.
This utility model has the advantages that：By arranging solar panel on the housing of remote-control key,Energy acquisition module and the battery being connected with solar panel is set in housing, it is possible thereby to electric energy is converted the solar into,The remote-control battery can be with life-time service without changing battery or charging；The shell of remote-control key can make once encapsulation knotStructure, waterproof sealing, pressure, shock resistance are good, are hardly damaged；The electricity that solar panel can be gathered by energy acquisition moduleCan be stored in super capacitor after carrying out boosting voltage stabilizing, power to master controller when required by energy acquisition module, energyAcquisition module can also by super capacitor overflow electrical power storage in lithium battery, which thereby enhance power-supply system safety andEfficiency during instantaneous heavy load.

Specific embodiment
Below with reference to accompanying drawing and in conjunction with the embodiments describing this utility model in detail.It should be noted that not rushingIn the case of prominent, the feature in embodiment and embodiment in this utility model can be mutually combined.
In one embodiment of novel maintenance-free remote-control key of the present utility model as shown in Figure 1 to Figure 3, the Novel freeSafeguard that remote-control key includes housing 10 and the master controller 20 that is arranged in housing 10 and lithium battery 30, housing 10 is provided with and masterThe operation button 11 that controller 20 is connected, master controller 20 are also associated with transmitting antenna 21, are additionally provided with recessed housing on housing 10Solar panel 40, is provided with the energy acquisition chip 50 being connected with solar panel 40, energy acquisition core in housing 10Piece 50 is connected with master controller 20, and solar panel 40 is electric with super capacitor 60 and lithium respectively also by energy acquisition chip 50Pond 30 is connected, and lithium battery 30 is connected with master controller 20 by the energy acquisition chip 50.It is understood that master controller20 and energy acquisition chip 50 include micro-control unit（Microcontroller Unit）, master controller 20 also includes letterNumber radiating circuit, micro-control unit and signal transmitting road are technology well known to those skilled in the art, will not be described here.The realityThe novel maintenance-free remote-control key in example is applied, and by solar panel being arranged on the housing of remote-control key, is set in housingThe energy acquisition module and battery being connected with solar panel is put, it is possible thereby to electric energy is converted the solar into, the remote control electricityPond can be with life-time service without changing battery or charging；The shell of remote-control key can make an encapsulating structure, waterproofSealing, pressure, shock resistance are good, are hardly damaged；The electric energy that solar panel is gathered can be risen by energy acquisition moduleIt is stored in super capacitor after pressure voltage stabilizing, powers to master controller when required by energy acquisition module, energy acquisition moduleThe electrical power storage that super capacitor can also be overflowed in lithium battery which thereby enhances the safety of power-supply system and instantaneously bears greatlyEfficiency during load；Specifically, solar panel, super capacitor and lithium battery can be individually for master controller and power, tooLithium battery power supply can be switched to immediately by energy-trap chip when positive energy cell panel and super capacitor electricity shortage, be improved instantaneous bigThe efficiency of load and the reliability of guarantee power supply, energy-trap chip also control the super-charge super-discharge protection of battery, it is ensured that the remote controlThe reliability of key working power.40 recessed housing 10 of solar panel causes solar panel 40 not protected by bruisingCard solar panel will not be damaged；The novel maintenance-free remote-control key is non-maintaining, classification of waterproof is high, long service life.
In the above-described embodiments, novel maintenance-free remote-control key also has following technical characteristic：The capacity of super capacitor 60For 0.1F to 1F, it is possible thereby to store the power consumption requirements that enough electric energy meet remote-control key；Solar panel 40 is using weakThe good non-crystalline silicon solar panel of photosensitiveness, can convert from ambient light light and obtain micro- electric energy as the energy of whole systemAmount source；Lithium battery 30 be chargeable lithium coin cells, energy acquisition module can also by super capacitor overflow electrical power storage arriveIn lithium battery, the efficiency when safety of power-supply system and instantaneous heavy load is which thereby enhanced.Housing 10 is resin-encapsulated housing,Inner insulating layer is provided with housing 10, operates button 11 using the silica gel button with 10 one of housing, waterproof sealing, pressure, anti-impactHit performance good, be hardly damaged.
