Specific embodiment

It is the correct selection in reversing starting point and orientation according to the key point moved backward into position, the present invention provides vehicle laser point Reversing auxiliary apolegamy part, i.e. reverse positioning laser beam emitting head 2 (Fig. 4), including closure 6 are embedded with light transmission glass on closure 6 Glass 8, there are two LED laser heads 7 for installation (i.e. in closure 6) after transparent glass 8.Two light that two LED laser heads 7 project It is marked on the reversing arc track on automobile rear ground, a cursor a little further is as moving backward into position at 90 degree of right angles Starting point anchor point, (see in Fig. 2 4) near 90 degree of reversing circular arc；Another a bit nearly cursor is as at 45 degree of oblique angles It moves backward into the starting point anchor point of position, (see in Fig. 2 3) near 45 degree of reversing circular arc.Circular arc of moving backward is deflecting roller hard-over The arc track that reversing occurs on the ground, and refer in particular to inner arc.As long as by the cursor on the ground close to parking stall Entrance one side doorframe or ground distributor every graticule (and pay attention into 90 degree right angles or 45 degree of oblique angles), steering wheel goes to bottom and moves backward It is as correct.

Principle is described as follows, and by taking position is moved backward in the intuitive left of driver's sight as an example, Fig. 2 is falling for 90 degree of left right angle What vehicle entered position plays point location figure, and parking prepares when reversing the direction of vehicle 1 and target parking position 5 into 90 degree of right angles, direction when reversing Disk quickly turns left moves backward on earth, and steering wheel is quickly reformed when vehicle enters 5 doorway of target parking position along reversing camber line.Because of light Punctuate 4 be exactly ground reversing arc track at 90 degree right angles point (central angle of this section of circular arc be 90 degree.It is practical to add one again A spacing distance), be aligned with target parking position entrance doorframe touchdown point or ground distributor every graticule (as long as it is practical close to, after It slightly corrects and is also acceptable in face).Note that minimum turning radius R=H/sinA, A are that deflecting roller is most when steering wheel goes to bottom Big corner, H are front and back wheel distance between axles.About 3 meters of trolley minimum turning radius R (refers to inner arc, and by calculating at maximum vehicle width). Fig. 3 is that moving backward for 45 degree of left oblique angle plays point location figure into position, and parking prepares the direction of vehicle 1 and target parking position 5 when reversing At 45 degree of oblique angles, cursor point 3 is exactly the point (midpoint of about mentioned-above 90 degree of cursors point 4) moved backward at 45 degree of circular arc, with Target parking position entrance doorframe touchdown point or ground distributor are aligned every graticule.The two be it is combinative, i.e., first by Fig. 2 it is at right angle It moves backward and is positioned into cursor 4, moved backward naturally by 45 degree of oblique angles shown in Fig. 3 into cursor 3 in the process of backing up, check point is Whether no alignment, angle are 45 degree, as pre-corrected.Later be familiar with, just directly by this 45 degree of closer oblique angle move backward into The position alignment of cursor 3 reversing is just.

The reversing of right enters a principle (Fig. 1) completely with above-mentioned left, and the cursor 4 and 45 degree for being also divided into 90 degree of right angles is oblique The cursor 3 at angle can only pass through the 2 cursor points at backsight sem observation rear for no other reason than that cursor positioning scenarios directly be can't see in blind area Alignment condition.

Left and right respectively sets a this reverse positioning laser beam emitting head 2 outside vehicle, and sets on driver behavior panel or steering wheel Have and opens control switch or button.In each reverse positioning laser beam emitting head 2 two LED laser heads 7 series winding through control switch, Contact again current-limiting resistance or equivalent driving circuit, with automobile 12V for being electrically connected.Two LED laser heads 7 are mounted on closed circle Anti-pollution or rainwater in cylindricality or semicircle shell 6, is only equipped with transparent glass 8 in light beam exit wound of bullet.

For the stability of laser beam irradiation position, reverse positioning laser beam emitting head 2 will mounted in rearward highest point to It is outer outstanding more reasonable, but Bindery security, aesthetics, it is generally arranged at the fixed part (circle of the two rearview mirror supports in left and right Fig. 4 of cylindrical outer cover is suitble to fill here) or roof rear portion both sides (being suitble to for semi-circular projection shape shell is horizontal mounted in here), also wrap Include pluggable separation or not pluggable separation.

The color of LED laser Shu Guangbiao routine is red, green, blue, and shape is also wrapped in addition to a basic dot " one " or " ten " font is included, the cursor of blinking form can be also designed to by driving circuit, is made more visible in the sun.
