This.Multiple groups lock-screw and threaded hole can be set, keep the fixation between light source module group 11 and shell 12 more firm.
Alternatively, can also be set up along it relative to the side that shell 12 moves on the lateral wall of light source module group 11 several
A threaded hole continues the threaded hole screwed in light source module group 11 after making the threaded hole 121 on the screw-in shell 12 of lock-screw 14, with
Realize the fixation between light source module group 11 and shell 12.Lock-screw 14 is set to screw in the threaded hole of different location in light source module group 1,
I.e. adjustable the distance between light outlets 111 and light hole 131.Alternatively, can also make be between light source module group 11 and shell 12
It is threadedly engaged.External screw thread is set on the lateral wall of light source module group 11, setting cooperates with the external screw thread on the inner wall of shell 12
Internal screw thread.
Certainly, the fixed form between light source module group 11 and shell 12 is not limited to above scheme, uses class in the prior art
As structure.
Groove 132 is equipped on end cap 13, groove 132 is located at the side of light hole 131 and is connected to light hole 131.?
Light barrier 133 is equipped in groove 132, light barrier 133 can slide in groove 132, to carry out different journeys to light hole 131
Degree blocks, to change the size of light hole 131.Light barrier 133 is equipped with sliding slot 1331, and fixed screw 135 passes through fixed block
Hole on 134 is connect with after the sliding slot 1331 on light barrier 133 with the threaded hole on end cap 13, and fixed block 134 is to will be light-blocking
Piece 133 is pressed in groove 132.When the shift position in groove 132 of light barrier 133, sliding slot 1331 will be relative to fixed screw
135 and fixed block 134 it is mobile, the setting of sliding slot 1331 behind 133 shift position of light barrier so that be still able to achieve between end cap 13
It is fixedly connected.Mobile relative to the position of light hole 131 by light barrier 133, adjustable light hole 131 is to light outlets 111
The coverage extent of the laser beam of sending, to change the length for the incident line being projected on projection surface.
Referring concurrently to Fig. 2, Fig. 2 shows the structural representations of the installation place of laser warning lamp in one embodiment of the invention
Figure.Laser warning lamp 1 is fixed on mounting rack 2, and mounting rack 2 is equipped with installation place 21.It is set on the shell 11 of laser warning lamp 1
There is hole location 122.Make screw 3 pass through hole location 122 to be threadedly engaged with installation place 21, to realize the fixation of laser warning lamp 1.When
So, it other conventional fixed forms such as is connected by a snap, is bonded or welded also may be used.
The structural schematic diagram of alarming light of vehicle in one embodiment of the invention is shown referring concurrently to Fig. 3 to 4, Fig. 3 to 4
(vertical view and side view).The car body 4 of automobile includes 44 on the right side of headstock 41, the tailstock 42, vehicle left side 43 and vehicle.It wherein, is edge on the left of vehicle
The left side of automobile direction of advance, vehicle right side is along the right side of automobile direction of advance.The fixing and mounting bracket 2 at headstock 41, two are swashed
Light warning lamp 1 is individually fixed in 41 both ends of headstock.Hole location is equipped on mounting rack 2 and headstock 41 to project for laser.
The laser beam that laser warning lamp 1 issues is projected on the ground of 4 left and right sides of car body and forms two incident lines 5.
In order to enable laser rays to be smoothly projeced into ground, need light emission side (being equipped with the side of end cap) court of laser warning lamp 1
Ground inclination (as shown in Figure 4).In order to play a warning role, the pedestrian and vehicle being located near automobile is enable accurately to estimate vehicle
Position to avoid vehicle, two incident lines 5 need on the outside of the contour line of car body 4, and between the contour line of car body 4
There is certain spacing.Therefore, it is also desirable to which the light emission side of laser warning lamp 1 is tilted (as shown in Figure 3) towards the outside of car body 4.
If desired the length for changing the incident line 5 can be rotated the end cap 13 on laser warning lamp 1, or adjustment laser warning lamp 1
Light source module group 11 protrude into the depth of shell 12.If desired the spacing between the incident line 5 and car body 4 is adjusted, it is alert that laser can be changed
Show the position that lamp 1 is installed on car body 4, or changes angle of the laser warning lamp 1 towards 4 outside of car body and ground.
Pedestrian or other vehicles near car body 4 close to when, due to the prompting of the incident line 5, pedestrian or other vehicles
It can go in advance far from car body 4 to other than the incident line 5, when it reaches the position of car body 4, will not collide or scrape with car body 4
It rubs.In order to improve warning, the assertive colours such as red can be set by the color for the laser rays that laser warning lamp 1 issues.
In the present embodiment, the both ends of headstock are provided with laser warning lamp, but can also be adjusted according to the actual situation.
For example, in the case where having shelter (side of such as car body closely wall) on the left of vehicle or on the right side of vehicle, it can be only the one of headstock
End setting laser warning lamp.In addition, laser warning lamp may also set up at the tailstock, or it is respectively provided at headstock and the tailstock.
In the present embodiment, laser warning lamp is set at headstock, and the incident line for being projeced into ground is along length over ends of body side
Extend to (length direction is the direction that automobile advances).Laser warning lamp can also be set on the left of vehicle and/or on the right side of vehicle, be made
The incident line extends along the width direction (width direction is the direction vertical with automobile direction of advance) of car body, or along length side
To and width direction have the incident line.
In the present embodiment, laser warning lamp is installed on to form alarming light of vehicle on automobile, in fact, having at other
It may also set up laser warning lamp in the equipment or article of risk, to play a warning role, improve safety.
It is to be illustrated to what preferable implementation of the invention carried out, but the invention is not limited to the implementation above
Example, those skilled in the art can also make various equivalent variations on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
