On personnel the outbound risk problem of personnel can occur due to effect of inertia, the present invention provides the electricity to solve the above problems
Motor-car descending safety arrestment circuit system.
The present invention is achieved through the following technical solutions:
Electric vehicle descending safety arrestment circuit system, including power supply VCC, motor M, descending safety arrestment circuit and speed regulation hand
Handle, the power supply VCC connection descending safety arrestment circuit, the speed adjusting lever connect the descending safety arrestment circuit,
The brake switch connects the descending safety arrestment circuit, and the descending safety arrestment circuit is connect with the motor；It is described
Descending safety arrestment circuit includes starting switch SB1, starting switch SB2, A.C. contactor KM1, A.C. contactor KM2, brake
Switch, descending auxiliary switch and electronic timer；The SB1 and A.C. contactor KM1 that starts switch is connected in series to form
Series arm 1, it is described to start switch SB2 and the A.C. contactor KM2 is connected in series to form series arm 2, series arm 1 with
Series arm 2 is connected in parallel, and is started switch the node between SB2 and the A.C. contactor KM2 described and is passed through the brake
Switch in parallel is connected to the road 2 of series connection, and the descending auxiliary switch is connected in series to form the road connected with the electronic timer
3, road 3 and the brake switch of series connection are connected in parallel.
The principle of above scheme of the present invention is: due to existing electric vehicle in descending often due to motor operating and the gradient
Booster action keep electric vehicle speed too fast and cause safety problem, in addition if taking emergency braking, electric vehicle in descending
On personnel the descendings safety problems such as the outbound risk of personnel can occur due to effect of inertia.The present invention is using the above scheme
By the road for the series connection that descending auxiliary switch in parallel on brake switch and electronic timer are formed, when electric car is in downhill running
In the state of, wheel drives motor M operating, and the conducting of descending auxiliary switch is closed at brake switch, short by electronic timer
The time control setting regular short circuit magneto motor lines of controller are connect, allows motor to form resistance, achievees the purpose that deceleration,
Increase descending safety.
The motor is magneto.
The present invention has the advantage that and the utility model has the advantages that
The present invention is by the combination to descending auxiliary switch, brake switch and electronic timer, when electric car is in lower hill wash
In the state of row, wheel drives motor M operating, and the conducting of descending auxiliary switch is closed at brake switch, passes through electronic timer
The time control setting regular short circuit magneto motor lines of controller are shorted, allows motor to form resistance, reaches the mesh of deceleration
, it realizes descending high security and convenience, ensure that the common security of people and Che.
