Description

Battery-driven car speed-limiting protection device
Technical field
The utility model relates to battery-driven car, especially relates to battery-driven car speed-limiting protection device.
Background technology
Battery-driven car especially electric motor car with two wheels is subjected to people's favor deeply with its laborsaving, convenient, economic environmental protection, extensively travels in urban and suburban roads as walking-replacing tool.Along with increasing sharply of quantity, bring many inconvenience also for control of traffic and road department thereupon, mainly show as and drive over the speed limit.Because two take turns battery-driven car and belong to unpowered vehicle, its brake system, speed-raising system all are different from self-propelled vehicle, in case et out of order or when complex situations occurring when running at high speed usually causes pernicious traffic accident to take place.Especially in the occasion of more-person-more-vehicle, as commuter time section, school doorway, traffic fork in the road etc.Therefore, electric motor car with two wheels exeeds the regulation speed to travel becomes a big hidden danger of Urban Road Traffic Accidents.
The utility model content
The utility model purpose is to provide a kind of branch place of realizing to carry out the battery-driven car speed-limiting protection device that speed limit is travelled.
For achieving the above object, the utility model can be taked following technical proposals:
Battery-driven car speed-limiting protection device described in the utility model, it comprises transmitter unit and receiving element; Described transmitter unit is made of encode circuit and the transmission circuit that is electrically connected on its mouth; Described receiving element is made of acceptor circuit, decoding scheme, handle control circuit, pulse width regulating circuit, circuit for controlling motor and sample circuit; Described acceptor circuit mouth is electrically connected with the decoding scheme input end; Decoding scheme mouth, handle control circuit mouth are electrically connected with the pulse width regulating circuit input end respectively; The pulse width regulating circuit mouth is electrically connected with the circuit for controlling motor input end; The circuit for controlling motor mouth is electrically connected with the sample circuit input end; The sample circuit mouth is electrically connected with the decoding scheme control end.
Be provided with control relay circuit at described pulse width regulating circuit mouth; Described control relay circuit is made of aerotron and the relay that is connected on its collecting electrode; The open contact of described relay is series at the power input of motor.
The utility model advantage just is to realize that branchs place carries out the traffic speed limit to battery-driven car and manage.During use, described transmitter unit is installed in the location that need carry out speed limit, when battery-driven car travels in this zone, location, the receiving element that is installed on the battery-driven car will be received the code signal that sends from transmitter unit, and export to decoding scheme; When this battery-driven car speed surpasses the speed limit that sets, the speed signal of circuit for controlling motor makes decoding scheme work through sample circuit, the pulse width regulating circuit input end is clamped in setting value, its mouth is controlled at unsaturated conducting state with the field effect transistor in the circuit for controlling motor, reduces to limit the battery-driven car moving velocity by restriction electric vehicle motor drive current.When battery-driven car speed was lower than the speed limit setting value, decoding scheme was not worked, and battery-driven car is in the cruising mode of operation.

The specific embodiment
As shown in the figure, battery-driven car speed-limiting protection device described in the utility model, it comprises transmitter unit and receiving element; Described transmitter unit is made of encode circuit and the transmission circuit that is electrically connected on its mouth; Encode circuit is made of integrated circuit PT2262, and its 17th pin is electrically connected with aerotron Q6 base stage in the transmission circuit that vibrates by resistance R 1.Described receiving element is made of acceptor circuit, decoding scheme, handle control circuit, pulse width regulating circuit, circuit for controlling motor and sample circuit; Integrated circuit MICRF002 the 10th pin in the acceptor circuit is electrically connected with the 14th pin of integrated circuit PT2272 in the decoding scheme, and the coding that receives is exported to decoding scheme; Simultaneously, the 17th pin of integrated circuit PT2272 is electrically connected with integrated circuit LM339 the 14th pin in the sample circuit in the decoding scheme, to obtain sampled signal; Integrated circuit LM339 the 8th pin in the sample circuit is electrically connected with circuit for controlling motor by sample circuit R13, gathers the battery-driven car speed signal; The output of decoding scheme is by the collecting electrode output of aerotron Q3, the collecting electrode of aerotron Q3 and handle control circuit mouth all are electrically connected with the 11st pin of integrated circuit MC33035 in the pulse width regulating circuit, the base stage of aerotron Q3 is electrically connected the grounded emitter of aerotron Q3 by the 13rd pin, the 12nd pin of integrated circuit PT2272 in resistance R 8, R9 and the decoding scheme respectively; When battery-driven car travelled below speed limit, decoding scheme was not worked like this, and aerotron Q3 ends, and the moving velocity of battery-driven car carries out regulating control by handle; When battery-driven car travels more than speed limit, the 12nd of integrated circuit PT2272 the or 13 pin output high level in the decoding scheme, aerotron Q3 amplifies conducting, the 11st pin of integrated circuit MC33035 in the pulse width regulating circuit is clamped at level on the low side, the 19th pin output low level of integrated circuit MC33035 is given the grid of field effect transistor T1, T2 in the circuit for controlling motor, make its be in unsaturated conducting state with the drive current of restriction electric vehicle motor M within setting range, play the speed limit effect.
The driving phenomenon takes place when preventing in the circuit for controlling motor that field effect transistor T1, T2 puncture, the 14th pin of integrated circuit MC33035 in the pulse width regulating circuit is electrically connected with the base stage of aerotron Q1 by resistance R 4, the grounded emitter of aerotron Q1 and collecting electrode are electrically connected with the 17th pin of integrated circuit MC33035 by the coil of relay J 1, and the open contact J11 of relay J 1 is series at the power input of motor.So when field effect pipe T1, T2 puncture, the 14th pin output low level of integrated circuit MC33035, aerotron Q1 ends, the coil losing electricity of relay J 1, the power supply that its open contact J11 action disconnects electric vehicle motor M forces battery-driven car to stop to travel.
