Utility model content
The utility model is for the deficiency existing for prior art, and it is simple, reasonable in design to provide a kind of structure, makes vehicle when moveing backward as the reversing fender guard based on braking during standstill that independently can carry out brake operating that faces a danger.
To achieve these goals, the utility model provides a kind of reversing fender guard based on braking during standstill, and comprise the radar being arranged on vehicle tail, described radar is connected with control circuit, and described control circuit comprises electromagnetic valve, and described electromagnetic valve connects described radar; Described electromagnetic valve is connected with braking during standstill gas circuit.
Wherein, described control circuit also comprises protection switch, and described protection switch one end connects described electromagnetic valve, and the other end is connected with relay; Described relay is connected with reversing switch.
Described braking during standstill gas circuit comprises relay valve, and described electromagnetic valve connects described relay valve, and described relay valve is connected to braking during standstill air receiver and braking during standstill air chamber.
Described electromagnetic valve is normal opened type electromagnetic valve.
Described protection switch is also connected with indicator lamp.
Described braking during standstill gas circuit also comprises braking during standstill main valve, and described electromagnetic valve is serially connected in described braking during standstill main valve delivery port and described relay valve controls between mouth.
Described reversing switch connects the control end of described relay, and described protection switch connects the mouth of described relay.
In use, be radar setting safety distance in advance, when this detections of radar has obstacle to vehicle tail and is less than setting value with the distance of obstacle, radar sends to electromagnetic valve signal, closed electromagnetic valve, and braking during standstill relay valve controls mouth and dies, braking during standstill starts, car brakeing.
The beneficial effect of this programme can be learnt according to describing of such scheme, and structure is simple, reasonable in design, making vehicle independently can carry out brake operating when moveing backward as faced a danger, ensure that safety during reversing.Arrange protection switch, so that chaufeur selects whether start automatic parking function, when protection switch closes, automatic parking function just works, and when protection switch closes simultaneously, indicator lamp can bright prompting chaufeur automatic parking function start; When not needing to start automatic parking function, close protection switch, actv. prevents the maloperation when not needing to be the potential danger that chaufeur brings, and improves usability and safety.Reversing switch connects the control end of relay, and protection switch connects the mouth of relay, and automatic parking function is only just worked when moveing backward.

Detailed description of the invention
For the technical characterstic of this programme can be clearly demonstrated, below by detailed description of the invention, this programme is set forth.
As shown in Figure 1, the utility model is a kind of reversing fender guard based on braking during standstill, and comprise the radar 11 being arranged on vehicle tail, radar 11 is connected with control circuit, and control circuit comprises normal opened type electromagnetic valve 8, and electromagnetic valve 8 connects radar 11; Control circuit also comprises protection switch 5, protection switch 5 one end connected electromagnetic valve 8, and the other end is connected with relay 3, and protection switch 5 connects the mouth of relay 3; Relay 3 is connected with reversing switch 4, and reversing switch 4 connects the control end of relay 3.Protection switch 5 is also connected with indicator lamp 6.
Electromagnetic valve 8 is connected with braking during standstill gas circuit, and braking during standstill gas circuit comprises relay valve 9, and electromagnetic valve 8 connects relay valve 9, and relay valve 9 is connected to braking during standstill air receiver 10 and braking during standstill air chamber 12 and braking during standstill air chamber 13.Braking during standstill gas circuit also comprises braking during standstill main valve 7, and electromagnetic valve 8 is serially connected in braking during standstill main valve 7 delivery port and relay valve 9 controls between mouth.
Be specially, in Fig. 1, in each valve class, alphabetical a represents the admission port of this valve, and b represents the air extractor duct of this valve, and c represents the relief port of this valve, and d represents the control mouth of this valve.
The admission port a of braking during standstill main valve 7 is connected with braking during standstill air receiver 10, and the air extractor duct b1 of braking during standstill main valve 7 is connected with normal open electromagnetic valve 8 admission port a, and normal open electromagnetic valve 8 air extractor duct b controls mouth d with relay valve 9 and is connected.
Relay valve 9 admission port a is connected with braking during standstill air receiver 10, and relay valve air extractor duct b is connected with braking during standstill air chamber 12 and braking during standstill air chamber 13 respectively.
Protection switch 5 is coupled twin switch, and key switch 2 one end of automobile is connected with car load storage battery 1 positive pole, and the other end is connected with control pin power end and one of them input pin III of protection switch 5 with the power supply input pin of relay 3 respectively.Storage battery 1 negative earth.
Control pin ground terminal is connected with connecing by reverse gear switch 4.
Indicator lamp 6 one end is connected with the output pin IV of protection switch 5, and the other end is connected to the ground.
Protection switch 5 input pin I is connected with the delivery port of relay 3, and the delivery port II of protection switch 5 is connected with electromagnetic valve one end, and the electromagnetic valve other end is connected with radar 11.
