Abstract

The invention relates to a safety-assistant scheme for a portable transportation vehicle to project grids on the ground, which belongs to the safety-assistant scheme for the portable transportation vehicles. The principle is that a projection device which is fixed on the transportation vehicle is utilized to project the grids on the front ground, and during the driving, a driver can directly master the front road condition change through observing the grid change. Moreover, the grid light can cause the attention of pedestrians and vehicles, and the position and safety range of the transportation vehicle can be indicated.

Description

Light vehicle safety subplan at ground projection grid

Technical field:

The invention belongs to the safe subplan of the light vehicle.

Background technology:

The light vehicle (such as bicycle, battery-driven car etc.) are not enough in illumination at night, when travelling in the environment with a varied topography, often can affect riding safety because the driver can't know the resolution landform.Meanwhile, pedestrian and vehicle often are difficult to notice the light vehicle at night, also bury potential safety hazard to night running.

Existing solution generally is to increase illumination equipment (such as accessories such as dynamo lighting sets) for these type of vehicle.But the effect of this solution is also not fully up to expectations.At first, houselights and ground are angled, and light can produce shade at recessed and high spot simultaneously, and these shades are easy to disturb the driver for the correct judgement of landform.Secondly, although the light of car light can cause the attention of passerby and vehicle, for the distance of these vehicle and all around safe range more visual information can't be provided, still may cause judging by accident, even accidents caused.

Summary of the invention:

The present invention is directed to above-mentioned these problems, from the angle of throwing but not throwing light on, and then obtain a kind of brand-new solution.Groundwork of the present invention is, installation auxiliary device on the light vehicle, this device throw one group of grid to the ground in vehicle the place ahead, and in advancing, the driver can grasp the place ahead landform intuitively by observing the variation of grid.Meanwhile, device and the light of grid can cause that pedestrian and vehicle note, and indicate the safe range of this vehicle the place ahead and both sides, with its ground location.

Imagination projection ground is desirable two dimensional surface, and the working direction of the vehicle is direction straight up, then throws grid thereon, should be an X-Y scheme.This figure can be various ways, but regardless of form, all should have certain regularity at visual cognition.This regularity can be linking up of certain form or repeat etc., so that when projection surface is irregular ground, the variation that grid produces according to ground, can be by the destruction of figure regularity, such as distortion or dislocation etc., arrived by the driver is observed, and grasp accordingly the variation of landform.Accompanying drawing 3 is the example of several possible raster plane figures.

Core concept of the present invention is to observe by the landform on projection ground by the variation of the grid in the movement.The luminous componen of grenade instrumentation can adopt the multiple comparatively proven technique modules such as laser module, LED projection; And the details such as the size of grid, quantity and color all do not affect the purport of invention.

Description of drawings:

Fig. 1: the scheme drawing of grenade instrumentation, this device mainly are comprised of battery module 1, stuck-module 2 (being fixed in the relevant position of the light vehicle, such as the handlebar stem of bicycle) and grid projection module 3.

Fig. 2: projecting lamp is fixed on the bicycle, at its ground, the place ahead projection grid.

Fig. 3: imaginary projection surface is desirable two dimensional surface, and the working direction of the vehicle is direction straight up, and then the X-Y scheme of projection grid thereon can be various ways.Be six kinds of possible grid that satisfy the described condition of preamble shown in the figure, but form is not limited to these six kinds.

Fig. 4: when grid was incident upon one section complex-terrain, the grid of seeing from driver's visual angle was according to the changing condition of landform.By distortion and the dislocation of grid, the driver can judge depression 5, projection 6 and the gentle slope 4 in this section landform intuitively.

The specific embodiment:

Such as Fig. 3, projector device is fixed on the bicycle relevant position, and angle has been proofreaied and correct errorless.Starter gear, device throws grid earthward.Such as Fig. 4, the driver can change the place ahead landform of grasping directly perceived by observing grid in the process of riding.Meanwhile, device and the light of grid can cause that pedestrian and vehicle note, and indicate the safe range of this vehicle the place ahead and both sides, with its ground location.The above-mentioned specific embodiment only is used for the present invention that explains, but not limits the invention.

Claims

1. light vehicle safety subplan, installation auxiliary device on the light vehicle helps the driver to observe the place ahead landform in the environment of insufficient light, and causes the attention of pedestrian and vehicle; It is characterized in that: described device throws one group of grid to the ground in vehicle the place ahead, and in advancing, the driver can grasp the place ahead landform intuitively by observing the variation of grid; And the light of grid can cause that pedestrian and vehicle note, and position and the safe range of these vehicle of indication.

2. safe subplan as described in claim 1, it is characterized in that: imagination projection ground is desirable two dimensional surface, the working direction of the vehicle is direction straight up, then throw the X-Y scheme of grid thereon, should have certain regularity at visual cognition, linking up or repeat etc. such as certain form, so that when projection surface is irregular ground, the variation that grid produces according to ground, can be by the destruction of figure regularity, such as distortion or dislocation etc., arrived by the driver is observed, and grasp accordingly the variation of landform.
