[detailed description of the invention]
Below in conjunction with detailed description of the invention and compare accompanying drawing this utility model is described in further details.
As shown in Figures 1 to 3, charging gun includes charging port 1, housing 2, charge button 3 and power port 4, light source 5 and control circuit plate (not shown).
In this detailed description of the invention, light source 5 includes substrate 502 and the light bar being arranged on substrate 502, and light bar is LED, is provided with multiple LED 501.Substrate 502 is arranged on the periphery of charging port 1, namely light source 5 is along the periphery cincture setting of charging port 1.So, the light source of this structure is arranged, and is suitable for gun body front end compact in design of charging, can the feature of perforate faciostenosis, meanwhile, can the region at effective lighting charging port place, thus for providing effective illumination during with charge port grafting on automobile.Preferably, substrate 502 be shaped as annular, the multiple LED 501 symmetrical distribution of annularly substrate in light bar.So, substrate and light bar are symmetrical set, and the position of the hole slot of the filling lamp bead that the charging port of the charging gun adapted is offered also is symmetrical, consequently facilitating process such charging port by mould.
Control circuit plate is arranged in housing 1.As shown in Figure 4, for the circuit connection diagram in charging gun.Control circuit plate 6 is provided with corresponding control module, and multiple pin.Wherein pin S1, S2 is switch controlling signal input pin, connects charge button 3.Pin S5, S6 are the first power input, connect power port 4, to receive external ac power source 9.Pin S3, S4 are second source input, connect battery 7, to receive the electricity supply of battery 7 when the first power input does not has power supply to input.The outfan of control circuit plate 6 connects light source 5, supplies the electricity of constant current constant voltage for the LED in light source 5.
During work, when pushing away before charge button 3, unlock charging port 1 so that charging port 1 can be connected with outside vehicle charging mouth.Meanwhile, when pushing away before charge button 3, external ac power source 9 carries out constant current constant voltage regulation by control circuit plate 6, powers light source 5.Under the irradiation of light source 5, user operation charging port 1 and the grafting of vehicle charging mouth.After charging port 1 and vehicle charging mouth grafting are good, charge button 3 resets, and charging port 1 is fixed together with vehicle charging mouth, and external ac power source 9 is vehicle charging by power port 4, charging port 1.Now, control circuit plate 6, according to the homing action of charge button 3, detects respective switch signal, controls light source 5 and extinguishes.
Being provided with battery 7 in foregoing circuit, power supply order is that external ac power source 9 is preferentially powered, and battery 7 is as compensating power supply.Control circuit plate 6 receives the electricity supply of battery 7 when the first power input does not has power supply to input.Battery 7 can be electrokinetic cell, and supply voltage can be such as 30V.By arranging battery, polytype power supply can be realized and power, power supply high-low pressure.
Preferably, control circuit plate 6 also includes battery charger (not shown in Fig. 4), and the input of battery charger connects the first power input, and outfan connects battery 7.So, when light source 5 is powered by external ac power source 9 by control circuit plate 6, also by battery charger, battery is charged, stored energy.
The charging gun of this detailed description of the invention, when charge button promotes, puts bright light source, provides enough illuminating raies for the connection procedure between the charge port on charging port and automobile.After both connect, after charge button resets, light source extinguishes, thus can provide light source lighting when sight line is poor, it is simple to the grafting between user operation port, it is ensured that the safety during use.Simultaneously, according to the charging port on charging gun, whether grafting is good with the charge port on automobile, whether i.e. charge button can reset, control light source to extinguish, thus port can be judged by the OFF state of lighting of light source whether grafting is good, work for charging gun provides instruction information, it is ensured that the effectiveness of work process.
Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to assert that of the present utility model being embodied as is confined to these explanations.For this utility model person of an ordinary skill in the technical field, make some replacements or obvious modification without departing from the concept of the premise utility, and performance or purposes are identical, all should be considered as belonging to protection domain of the present utility model.
