Above-mentioned a kind of deceleration driven is characterized in that: said visual impact piece one is triangle, and said visual impact piece two forms tetragonal triangle or trapezoidal for matching with said visual impact piece one, and said visual impact piece three is a rhombus.

Above-mentioned a kind of deceleration driven is characterized in that: the length of said visual impact piece one is 80mm～130mm, and width is 200mm～300mm; The length of said visual impact piece two is 80mm～100mm, and width is 200mm～300mm; The length of said visual impact piece three is 250mm～350mm, and width is 200mm～300mm.

Above-mentioned a kind of deceleration driven is characterized in that: said deceleration strip body is speed-reducing rubber band body or plastic-steel deceleration strip body.

The utility model compared with prior art has the following advantages:

1, the utility model is simple in structure, and novel and reasonable design is easy to install.

2, the utility model is through be provided with a plurality of plane visual impact unit in the section of going up a slope continuously; Said plane visual impact unit comprises the tangible visual impact piece of mutual aberration one, visual impact piece two and visual impact piece three; Said visual impact piece two is between visual impact piece one and visual impact piece three; Thereby when vehicle proximity deceleration; Give driver and crew's visual impact and caution, driver and crew can feel the deceleration strip height apparently higher than actual height, thereby play the effect that the driver is initiatively slowed down.

3, the realization cost of the utility model is low, and result of use is good, is convenient to promote the use of.

In sum, the utility model is simple in structure, and novel and reasonable design is given driver and crew's visual impact and caution, has improved vehicle running smoothness and safety by bus, is convenient to promote the use of.

Through accompanying drawing and embodiment, the technical scheme of the utility model is done further detailed description below.

The specific embodiment

A kind of deceleration driven as depicted in figs. 1 and 2; Comprise the deceleration strip body; Said deceleration strip body comprise the upward slope section 1 of meeting to direction to the car, dorsad direction to the car lower slope section 3 and be used to be connected the horizontal linkage section 2 of section 1 and lower slope section 3 of going up a slope; The upper end of said go up a slope section 1 and lower slope section 3 all tilts to horizontal linkage section 2; Its length direction of said upward slope section 1 upper edge is provided with a plurality of plane visual impact unit continuously; Said plane visual impact unit comprises tangible visual impact piece one 3-1 of mutual aberration, visual impact piece two 3-2 and visual impact piece three 3-3, and said visual impact piece two 3-2 are between visual impact piece one 3-1 and visual impact piece three 3-3.

As shown in Figure 1, said visual impact piece one 3-1 is a triangle, and said visual impact piece two 3-2 form tetragonal triangle or trapezoidal for matching with said visual impact piece one 3-1, and said visual impact piece three 3-3 are rhombus.The length of said visual impact piece one 3-1 is 80mm～130mm, and width is 200mm～300mm; The length of said visual impact piece two 3-2 is 80mm～100mm, and width is 200mm～300mm; The length of said visual impact piece three 3-3 is 250mm～350mm, and width is 200mm～300mm.Said deceleration strip body is speed-reducing rubber band body or plastic-steel deceleration strip body, and said deceleration strip body also can be processed by metal material.

During use; Said visual impact piece one 3-1 adopts white, and said visual impact piece two 3-2 adopt blue, and said visual impact piece three 3-3 adopt yellow; Make the driver near deceleration strip the time, produce stereo-picture; Can feel the higher and reduction of speed of deceleration strip height, horizontal linkage section 2 adopts pure whites with lower slope section 3, and its mounting method is the same with existing traditional deceleration strip.Deceleration driven should vehicle be lower than speed limit through the time impact for a short time, passenger comfort does not produce big influence; When the speed of a motor vehicle was higher than speed limit, vehicle can produce violent vibration, produced intense stimulus for driver and crew's psychology and physiology.Therefore the deceleration strip size should require design according to different deceleration values, and deceleration strip height b and descending branch length X m and speed limit Vm relation equation are:

$\mathrm{Vm}\≥3.6\sqrt{\frac{g}{2b}}\·\mathrm{Xm}---\left(1\right)$

In the relation equation (1), Vm is a speed limit;

Xm is a deceleration strip descending branch length;

B is the deceleration strip height.

The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any restriction; Every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of the utility model technical scheme.
