Background technology
Embrace the car The whole control system and be divided into power control system and hydraulic control system, wherein TRACTION CONTROLLER is the power traction control system, main startup of being responsible for embracing car, advance, retreat, warning, light and acceleration and deceleration.PUMP CONTROLLER is hydraulic pump control in addition, main rising, decline, upset, opening and closing of being responsible for embracing car clip pack device.
Embrace in the car use when navigating mate and take when embracing car, the SEAT SW seat switch in the circuit is connected, navigating mate with key start embrace car after, the connection of KEY SW key switch.At this time navigating mate starts an armful car ACC START SW start switch, navigating mate depresses forward gear FWD or retreats retaining REW pedal, if navigating mate was forgotten and was unclamped parking brake this moment, but the power traction control system of whole armful of car is all connected, embracing car is driven by force, but parking brake has limited the driving of armful car from machinery again, and the result causes armful car on fire because overload operation causes embracing the car electric elements.This reason of several causes has taken place at present caused embracing the situation that the car electric elements damages, and it is relatively more expensive to change armful car electric elements, brings bigger economic loss; Electric also existence on fire causes the hidden danger of fire in addition, and that will bring bigger and immeasurable loss.
Summary of the invention
The utility model provides a kind of armful of driver the safety control of stopping, and can solve navigating mate and forget when unclamping parking brake, embraces a car and is forced to drive and causes the electric current overload, the problem such as electric on fire of damaging that circuit module causes.
A kind of armful of driver safety control of stopping comprises near switch, intermediate relay ZJ, first indicator lamp, second indicator lamp, describedly is located at place, parking brake stroke position near switch, in order to detect the position of parking brake; Electrical equipment ZJ comprises coil, the first switch ZJ1 and second switch ZJ2 in the middle of described the continuing, the described series connection with the coil of intermediate relay ZJ near switch afterwards inserted between the signal power source AB, the first switch ZJ1 and second switch ZJ2 are single pole double throw switch, the moving contact a of the described first switch ZJ1 is connected with the end of signal power source AB, and two break back contact b, the c of the described first switch ZJ1 are connected in series the other end that inserts signal power source AB behind first indicator lamp, second indicator lamp respectively; The moving contact d of described second switch ZJ2 inserts and embraces the move forward and backward end of control loop CD of car, and one of them break back contact f inserts the other end of the control loop CD that moves forward and backward, and another break back contact e is vacant state.
Further, first indicator lamp is red light, and second indicator lamp is green light.
Further, at flywheel diode of the coil two ends of intermediate relay ZJ access in parallel.
The utility model utilization can actv. will be embraced driver's current state of stopping near switch and intermediate relay and be fed back with signal lamp, make proper operation in order to point out navigating mate; Can effectively prevent from embracing car again and can't drive the electric original paper of embracing car and causing under the situation of pine at parking brake and damage, well protect each electric original paper of armful car, postpone the service life of armful car, save the productive costs of enterprise greatly; That has avoided that navigating mate parking brake misoperation causes embraces car electric elements fault and safety misadventure, has improved the safety performance of armful car largely.
Description of drawings
Fig. 1 is that the utility model is embraced the stop schematic circuit diagram of safety control of driver.
Among the figure: 1-is near switch, 2-first indicator lamp, 3-second indicator lamp, 4-flywheel diode, ZJ-intermediate relay, ZJ1-first switch, ZJ2-second switch.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described.
Figure 1 shows that the utility model embraces the stop schematic circuit diagram of safety control of driver, described armful of driver safety control of stopping comprises near switch 1, intermediate relay ZJ, first indicator lamp 2, second indicator lamp 3, describedly be located at parking brake stroke position place near switch 1, in order to detect the position of parking brake; The described series connection with the coil of intermediate relay ZJ near switch 1 afterwards inserted between the signal power source AB; preferable; at flywheel diode 4 of the coil two ends of intermediate relay ZJ access in parallel; and with its formation loop; the high electro-motive force that makes its generation in the loop with continuous current system consumption, thereby play the not impaired effect of element in the protective circuit.
Described intermediate relay ZJ also comprises the first switch ZJ1 and second switch ZJ2, the first switch ZJ1 and second switch ZJ2 are single pole double throw switch, the moving contact a of the described first switch ZJ1 is connected with the end of signal power source AB, and two break back contact b, the c of the described first switch ZJ1 are connected in series the other end of first indicator lamp 2, second indicator lamp, 3 back access signal power source AB respectively.The moving contact d of described second switch ZJ2 inserts and embraces the move forward and backward end of control loop CD of car, and one of them break back contact f inserts the other end of the control loop CD that moves forward and backward, and another break back contact e is vacant state.
Principle of work of the present utility model is described below:
When parking brake is not released, near switch 1 induction less than the parking brake position and feed back to intermediate relay ZJ, contact a, the b of the intermediate relay ZJ dead electricity first switch ZJ1 connects, and first indicator lamp 2 (red light) in the control circuit is connected, and red light lighted and represented that parking brake is pulled up this moment; Intermediate relay ZJ disconnects simultaneously embraces car and moves forward and backward that (contact d, the f of second switch ZJ2 disconnects control loop, contact d is connected) with f, at this time embracing the power traction control system of car can't connect, embracing car can't drive, embrace car this moment and be in dead ship condition, so just pine and embrace the driven situation of car of parking brake can not occur, just can guarantee well that electric elements normally can overload and damage.
Otherwise, when parking brake is released, to sense the parking brake position and feed back to intermediate relay ZJ near switch 1, this moment, intermediate relay ZJ got contact a, the c connection of the electric first switch ZJ1, connect second indicator lamp 3 (green light) in the control circuit, it is released that this moment, green light lighted the expression parking brake; Intermediate relay ZJ is connected simultaneously and is embraced the car control loop CD (the contact d of second switch ZJ2, f closure) that moves forward and backward, and at this time embraces car and just can driven travel.
The utility model utilization can actv. will be embraced driver's current state of stopping near switch and intermediate relay and be fed back with signal lamp, make proper operation in order to point out navigating mate; Can effectively prevent from embracing car again and can't drive the electric original paper of embracing car and causing under the situation of pine at parking brake and damage, well protect each electric original paper of armful car, postpone the service life of armful car, save the productive costs of enterprise greatly; Most critical be avoided that navigating mate parking brake misoperation causes embrace car electric elements fault and safety misadventure, improved the safety performance of armful car largely.
