Background technology
When testing automobile radar for backing car coverage, in traditional method of testing, need the graticule of drafting one width 3m × 3m, volume is larger, long-time easy to wear on the ground, and need for different tests the graticule drawing plurality of specifications, draw, preserve and carry all extremely inconvenient.
Utility model content
In order to solve papery graticule used when testing automobile radar for backing car coverage, draw difficult and preserve and carry the problem of inconvenience, the utility model provides a kind of equipment drawn for graticule.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The utility model provides a kind of equipment drawn for graticule, comprising: mounting bracket and the imaging device be arranged on described mounting bracket, and wherein, described imaging device comprises: laser beam emitting device; At least one imaging waffle slab, be arranged on the front of described laser beam emitting device, dismountablely be arranged in described imaging device, wherein, on described imaging waffle slab, at least one imaging waffle slab, is arranged on the front of described laser beam emitting device, described imaging waffle slab is formed with multiple horizontal edge and multiple longitudinal edge, described horizontal edge intersects mutually with longitudinal edge, limits multiple net region; Wherein, described horizontal edge and the equal printing opacity of longitudinal edge, described net region is light tight; Be arranged on the reflection unit in described imaging waffle slab front, the reflecting surface of described reflection unit is towards described imaging waffle slab; And being set in the shell of described laser beam emitting device, described imaging waffle slab and described reflection unit outside, the bottom of described shell offers a through hole passed through for light, and described through hole is just to the below of described reflection unit.
Further, described laser beam emitting device comprises: generating laser and the concavees lens group for making laser disperse, and described concavees lens group is arranged on the front of described generating laser, and described concavees lens group comprises multiple concavees lens.
Further, described imaging waffle slab is marked with coordinate figure.
Further, described imaging waffle slab is mobilizable is arranged in described shell.
Further, the reflecting surface of described reflection unit and horizontal direction are miter angle.
Further, described reflection unit is level crossing.
The beneficial effects of the utility model are: the equipment for graticule drafting that the utility model provides is in the mode of laser projection, draw graticule on the ground quickly and easily, and by being replaced with the graticule that can project into different size as waffle slab, thus more simple, the convenience that the drafting of graticule is become.

Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
As shown in Figure 1, the utility model embodiment provides a kind of equipment drawn for graticule, comprising: mounting bracket 1 and the imaging device 2 be arranged on described mounting bracket 1.Wherein, described imaging device 2 comprises:
Laser beam emitting device 3, described laser beam emitting device 3 comprises: generating laser 7 and the concavees lens group 8 for making laser disperse, described concavees lens group 8 is arranged on the front of described generating laser 7, and concavees lens group 8 comprises multiple concavees lens.The laser sent due to generating laser 7 is multiple laser beam forms, be smaller round dot when on laser beam converge a to plane, being difficult to realization makes laser be paved with whole plane, therefore can a concavees lens group 8 be set before generating laser 7, when laser beam is by producing disperse function during concavees lens, thus the area increased when laser is mapped to plane, laser is made to be paved with whole plane, as shown in Figure 2, the principle schematic of the laser beam emitting device Emission Lasers provided for the utility model embodiment.
At least one imaging waffle slab 4, is arranged on the front of laser beam emitting device 3, is dismountablely arranged in imaging device 2, can carry out the replacement of the imaging waffle slab 4 of different size as required.As shown in Figure 3, imaging waffle slab is formed with multiple horizontal edge and multiple longitudinal edge, described horizontal edge intersects mutually with longitudinal edge, limits multiple net region; Wherein, described horizontal edge and the equal printing opacity of longitudinal edge, described net region is light tight.
Reflection unit 5, is arranged on the front of imaging waffle slab 4, is a predetermined angular with horizontal direction.The reflecting surface of this reflection unit 5 towards imaging waffle slab 4, to realize reflex.In order to save manufacturing cost, reflection unit 5 can select level crossing.And
Be set in the shell 6 of laser beam emitting device 3, imaging waffle slab 4 and reflection unit 5 outside, the bottom of this shell 6 offers the through hole passed through for light for, and this through hole is just to the below of reflection unit 5.
As shown in Figure 4, for the utility model embodiment provide for graticule draw equipment use scene schematic diagram.In use, first this equipment is placed on the geographic position being beneficial to and carrying out testing automobile radar for backing car coverage, then laser beam emitting device 3 is opened, the laser that generating laser 7 is sent produces disperse function by concavees lens group 8, thus make laser be paved with imaging waffle slab 4, because imaging waffle slab 4 only has horizontal edge and longitudinal edge section printing opacity, so under the reflex of the reflecting surface of reflection unit 5, just required graticule can be formed on the ground.In order in reflection process, ensure to project to ground graticule indeformable, the reflecting surface of reflection unit 5 and horizontal direction can be made to be miter angle.
In addition, for the ease of identifying the parameter specification of each imaging waffle slab 4, imaging waffle slab 4 is also marked with coordinate figure.
Further, imaging waffle slab is also mobilizable is arranged in described shell.Imaging waffle slab 4 can carry out the movement of fore-and-aft direction in the horizontal direction, thus controls the size of projection grid.
In addition, also by raising or reducing mounting bracket 1, the size of projection grid is controlled.
Above-described is preferred implementation of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not departing under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
