Traditional reversing aid system is to utilize radar or camera technique to catch the information of obstacle, and after treatment with distance, signal feedback such as orientation are given chaufeur, in fact only played auxiliary effect, but above-mentioned problem can't solve still.
Summary of the invention
There are the problems referred to above in the utility model to existing technology, has proposed a kind of reverse aid, and this reverse aid can be pointed out the position of chaufeur wheel accurately, avoids maloperation and causes accident.
The utility model is realized through following technical proposal: a kind of reverse aid; Comprise feed circuit and the rotary angle transmitter that is used to respond to the bearing circle rotational angle; It is characterized in that this reverse aid also comprises the display module that is used to show the tire deflection angle, the input end of said rotary angle transmitter is connected with feed circuit; The mouth of said rotary angle transmitter is connected with display module, the ground terminal ground connection of said rotary angle transmitter.
Feed circuit power supply when the rotary angle transmitter input end; Rotary angle transmitter is according to the angle position of current bearing circle; Produce a signal; Described signal carries out treatment conversion at sensor internal, and the signal of display module after with treatment conversion show, thereby reminds the steering angle of chaufeur tire.
In above-mentioned reverse aid, described rotary angle transmitter is arranged in the wheel steering post.Rotary angle transmitter is arranged on the interior convenience of Steering gear and detects the angular signal of bearing circle accurately.
In above-mentioned reverse aid, described display module is the mechanical type DC voltmeter, on the dial plate of this DC voltmeter, is carved with three scale marks.Three scales are respectively " 1 ", " 2 ", " 3 ", when pointed " 1 ", represent that then bearing circle got to the position on a left side; When pointed " 2 ", represent that then bearing circle mediates; When pointed " 3 ", represent that then bearing circle got to the rightest position.
In above-mentioned reverse aid, described feed circuit comprise a lead, and this lead one end is connected with the reversing automobile lamp, and the other end is connected with the input end of above-mentioned rotary angle transmitter.When automobile was hung into reverse gear, input end got electric rotary angle transmitter and starts working.
In above-mentioned reverse aid, described rotary angle transmitter is the electric resistance partial pressure sensor.The input end energising, rotary angle transmitter utilizes the electric resistance partial pressure effect principle according to the position of bearing circle, produces a voltage signal, thereby utilizes voltage signal to reflect that steering wheel position lets chaufeur understand the tire position of automobile.
In above-mentioned reverse aid, described display module is located on the Auto Instrument desk.Display module is arranged on the instrument desk more intuitively gives chaufeur message feedback.
In above-mentioned reverse aid, be in series with hand switch between the input end of said rotary angle transmitter and the feed circuit.Hand switch is set can be selected to open or closing control to this device according to actual conditions.
In above-mentioned reverse aid, the voltage of described rotary angle transmitter output is vdc.
Compared with prior art, the housing of this dynamo governor has the following advantages:
1, real-time and effective reflects the residing position of tire, and driver assistance person parks safely and effectively.
2, only need a rotation direction sensor, simple in structure, cost is low, and is easy to implement.
3, be provided with hand switch, have more hommization.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, bearing circle; 2, feed circuit; 3, rotary angle transmitter; 4, display module; 5, input end; 6, mouth; 7, ground terminal; 8, hand switch.
The specific embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1, a kind of reverse aid comprises feed circuit 2 and the rotary angle transmitter 3 that is used to respond to bearing circle 1 rotational angle; This reverse aid also comprises the display module 4 that is used to show the tire deflection angle, and the input end 5 of rotary angle transmitter 3 is connected with feed circuit 2, and the mouth 6 of rotary angle transmitter 3 is connected with display module 4; Ground terminal 7 ground connection of rotary angle transmitter 3; Rotary angle transmitter 3 is arranged in bearing circle 1 Steering gear, and display module 4 is the mechanical type DC voltmeter, on the dial plate of this DC voltmeter, is carved with three scale marks; Three scales are respectively " 1 ", " 2 ", " 3 "; Feed circuit 2 comprise a lead, and this lead one end is connected with the reversing automobile lamp, and the other end is connected with the input end 5 of rotary angle transmitter 3; Rotary angle transmitter 3 is the electric resistance partial pressure sensor, and display module 4 is located on the Auto Instrument desk, is in series with hand switch 8 between the input end 5 of rotary angle transmitter 3 and the feed circuit 2, and the voltage of rotary angle transmitter 3 outputs is vdc.
When automobile is hung into reverse gear; Input end 5 energisings of rotary angle transmitter 3, rotary angle transmitter 3 gets electrician's work at this moment, and rotary angle transmitter 3 detects current voltage signal and signal output is arrived display module 4; Rotary angle transmitter 3 utilizes the electric resistance partial pressure effect to process; Rotary angle transmitter 3 in-to-in resistance change when bearing circle 1 deflection angle changes then, and then the voltage of output has produced corresponding variation, and three scales on the display module 4 are being represented three directions; When pointed " 1 ", represent that then bearing circle 1 got to the position on a left side; When pointed " 2 ", represent that then bearing circle 1 mediates; When pointed " 3 ", represent that then bearing circle 1 got to the rightest position, when pointer declines on scale mark; Then that scale of pointer deflection is bearing circle 1 steering direction; Drop between " 1 " and " 2 " like pointer, prove that the tire position takes back, beat straight bearing circle 1 like need; Only need bearing circle 1 deflection is to the right fallen the position of " 2 " up to pointer, bearing circle 1 deflection is left dropped on " 1 " position up to pointer as killing 1 of bearing circle left.Clear current bearing circle 1 deflection angle that reflects of three scale marks of display module 4, chaufeur only need be observed display module 4 and understand the residing position of vehicle tire, driver assistance person's reversing.This device is more humane is provided with hand switch 8, and chaufeur can be controlled the open and close of this device as required, when hand switch 8 is in opening; When vehicle is hung into reverse gear; This device is opened automatically, and when hand switch 8 was in closed condition, this device was in closed condition.
