In addition, the descriptions of up, down, left, right, front, back, etc. used in the present invention are only relative to the relative positional relationship of the components of the present invention in the drawings.
[0026] In addition, unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art. The terms used in this specification are only for describing specific embodiments, not for limiting the present invention. The term "and / or" used herein includes any combination of one or more related listed items.
[0027] Reference Figure 1, showing a schematic diagram of the structure of a laser warning light in one embodiment of the present invention. The laser warning light 1 comprises a light source module 11, a housing 12 and an end cover 13. The housing 12 is provided with a receiving cavity, and the light source module 11 extends into the receiving cavity of the housing 12 from an opening at one end of the housing 12. The end cover 13 is provided at the end of the housing 12, and a light outlet hole 131 is provided on the end cover 13.
[0028] The light source module 11 includes components such as a laser source and a lens. The laser emitted by the laser source is refracted by the lens to form an "I"-shaped light beam, and is emitted from the light-emitting port 111. This part of the content belongs to the prior art and is not described here. The light emitted from the light-emitting port 111 is projected onto the projection surface after passing through the light-emitting hole 131, and a projection line is formed on the projection surface. Generally, the projection line can be used to demarcate areas and mark boundaries, etc.
[0029] The light source module 11 can be moved in the housing 12 to adjust the distance between the light emitting port 111 and the light exit hole 131 , thereby changing the length of the projection line projected onto the projection surface.
[0030] In this embodiment, there is a clearance fit between the light source module 11 and the housing 12, and a threaded through hole 121 is provided on the housing 12. When the front end of the light-emitting port 111 provided on the light source module 11 extends into the accommodating cavity of the housing 12, the distance between the light-emitting port 111 and the light-emitting hole 131 is adjusted to a set value (set according to the required length of the projection line), and the locking screw 14 is screwed into the threaded hole 121, and the front end of the locking screw 14 is pressed against the outer wall of the light source module 11, thereby realizing the position locking between the light source module 11 and the housing 12. Figure 1 As shown in FIG. 1 , only one locking screw 14 and threaded hole 121 are provided, but the present invention is not limited thereto. Multiple sets of locking screws and threaded holes can be provided to make the fixing between the light source module 11 and the housing 12 more stable.
[0031] Alternatively, a plurality of threaded holes may be provided on the outer wall of the light source module 11 along the direction in which it moves relative to the housing 12, so that the locking screw 14 is screwed into the threaded hole 121 on the housing 12 and then further screwed into the threaded hole on the light source module 11, so as to achieve the fixation between the light source module 11 and the housing 12. By screwing the locking screw 14 into the threaded holes at different positions on the light source module 11, the distance between the light emitting port 111 and the light emitting hole 131 can be adjusted. Alternatively, the light source module 11 and the housing 12 may be threadedly matched. An external thread is provided on the outer wall of the light source module 11, and an internal thread matching the external thread is provided on the inner wall of the housing 12.
[0032] Of course, the fixing method between the light source module 11 and the housing 12 is not limited to the above solution, and similar structures in the prior art can be used.
[0033] A groove 132 is provided on the end cover 13. The groove 132 is located at one side of the light exit hole 131 and is connected to the light exit hole 131. A light blocking sheet 133 is provided in the groove 132. The light blocking sheet 133 can slide in the groove 132, thereby blocking the light exit hole 131 to different degrees to change the size of the light exit hole 131. A slide groove 1331 is provided on the light blocking sheet 133. The fixing screw 135 passes through the hole on the fixing block 134 and the slide groove 1331 on the light blocking sheet 133 and is connected to the threaded hole on the end cover 13. The fixing block 134 is used to press the light blocking sheet 133 into the groove 132. When the light blocking sheet 133 moves in the groove 132, the slide groove 1331 will move relative to the fixing screw 135 and the fixing block 134. The setting of the slide groove 1331 enables the light blocking sheet 133 to still be fixedly connected to the end cover 13 after the light blocking sheet 133 moves. By moving the light blocking sheet 133 relative to the light exit hole 131 , the degree to which the light exit hole 131 blocks the laser light emitted from the light emitting port 111 can be adjusted, thereby changing the length of the projection line projected onto the projection surface.
[0034] Also refer to Figure 2 , Figure 2 The schematic diagram of the structure of the installation of the laser warning light in one embodiment of the present invention is shown. The laser warning light 1 is fixed on the mounting frame 2, and the mounting frame 2 is provided with a mounting portion 21. A hole 122 is provided on the housing 12 of the laser warning light 1. The screw 3 passes through the hole 122 and is threadedly engaged with the mounting portion 21, thereby achieving the fixation of the laser warning light 1. Of course, other conventional fixing methods such as snap connection, bonding or welding are also possible.
[0035] Also refer to Figures 3 to 4 , Figures 3 to 4 The schematic diagram of the structure of the automobile warning light in one embodiment of the present invention (top view and side view) is shown. The body 4 of the automobile includes the front 41, the rear 42, the left side 43 and the right side 44. The left side is the left side along the forward direction of the automobile, and the right side is the right side along the forward direction of the automobile. The mounting frame 2 is fixed at the front 41, and two laser warning lights 1 are respectively fixed at both ends of the front 41. Holes are provided on the mounting frame 2 and the front 41 for laser emission.
[0036] The laser light emitted by the laser warning light 1 is projected onto the ground on the left and right sides of the vehicle body 4 to form two projection lines 5. In order to smoothly project the laser line onto the ground, the light emitting side (i.e., the side with the end cap) of the laser warning light 1 needs to be tilted toward the ground (e.g., Figure 4 In order to play a warning role and enable pedestrians and vehicles near the car to accurately estimate the position of the car and avoid it, the two projection lines 5 need to be located outside the contour line of the car body 4 and have a certain distance from the contour line of the car body 4. Therefore, it is also necessary to tilt the light emitting side of the laser warning light 1 toward the outside of the car body 4 (as shown in FIG. Figure 3shown).
[0037] If the length of the projection line 5 needs to be changed, the end cap 13 on the laser warning light 1 can be rotated, or the depth of the light source module 11 of the laser warning light 1 extending into the housing 12 can be adjusted. If the distance between the projection line 5 and the vehicle body 4 needs to be adjusted, the position where the laser warning light 1 is installed on the vehicle body 4 can be changed, or the angle of the laser warning light 1 toward the outside of the vehicle body 4 and the ground can be changed.
[0038] When pedestrians or other vehicles near the vehicle body 4 approach, due to the reminder of the projection line 5, the pedestrians or other vehicles will move away from the vehicle body 4 in advance and move beyond the projection line 5. When they reach the position of the vehicle body 4, they will not collide or scratch the vehicle body 4. In order to improve the warning, the color of the laser line emitted by the laser warning light 1 can be set to a striking color such as red.
[0039] In this embodiment, laser warning lights are provided at both ends of the front of the vehicle, but they can also be adjusted according to actual conditions. For example, when there is an obstruction on the left or right side of the vehicle (such as one side of the vehicle body is close to a wall), a laser warning light can be provided only at one end of the front of the vehicle. In addition, the laser warning light can also be provided at the rear of the vehicle, or at both the front and rear of the vehicle.
[0040] In this embodiment, the laser warning light is arranged at the front of the vehicle, and the projection line projected on the ground extends along the length direction of the vehicle body (the length direction is the direction in which the vehicle moves forward). The laser warning light can also be arranged on the left side and / or the right side of the vehicle, so that the projection line extends along the width direction of the vehicle body (the width direction is the direction perpendicular to the direction in which the vehicle moves forward), or has projection lines in both the length direction and the width direction.
[0041] In this embodiment, the laser warning light is installed on the car to form a car warning light. In fact, the laser warning light can also be set on other dangerous equipment or objects to play a warning role and improve safety.
[0042] The above is a specific description of the preferred implementation of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
