[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0032] The present invention has a small size and low manufacturing cost. The setting of a spherical or spherical solid carrier structure can realize universal angle adjustment when the present invention is installed and used. Since the laser is easy to generate heat when working, in the present invention, the solid carrier, the light receiving part, the lens frame, the first connecting part, the second connecting part and the laser head base are all made of metal materials to facilitate the heat dissipation of the laser emitting device when working to prevent fatigue driving. Considering the heat dissipation effect and cost, the material is preferably copper or aluminum. In addition, the solid carrier, the light receiving part and the lens frame are all made of metal materials that have been treated with anti-oxidation to increase their service life.

[0034] like Figures 1-6 As shown, a laser emitting device for preventing fatigue driving includes a spherical or spherical solid carrier 1, a laser 3 with a laser head 2, and a main controller (not shown in the figure). The laser 3 has a built-in control chip, which communicates with the main controller in real time and controls the laser 3 to emit laser after receiving the control signal sent by the main controller.

[0035] In addition, the laser 3 further includes a laser head base 5. The laser head 2 is connected to the laser head base 5 by any one of mechanical connection, mechanical fit, or hot melt connection, and then a connection structure is formed in which the laser head base 5 wraps around the laser head 2.

[0036] The solid carrier 1 has a laser channel 4 that completely penetrates both sides of the solid carrier 1 for laser projection. The laser 3 is disposed in the laser channel 4 and integrated with the solid carrier 1. The solid carrier 1 and the laser 3 are connected by any one of mechanical connection, mechanical fit, or hot melt connection.

[0037] In this embodiment, the spherical or similar spherical solid carrier 1 is made of copper treated against oxidation. Copper has a high thermal conductivity and good heat dissipation performance, which can ensure that the laser emission device for preventing fatigue driving can dissipate heat quickly during use.

[0039] Based on the structure of Embodiment 1, in Embodiment 2, as Figure 3 shown, the laser emission device for preventing fatigue driving further includes a hollow first connecting member 6. The two ends of the first connecting member 6 are respectively connected to the laser channel 4 and the laser 3, and then a connection structure is formed in which the solid carrier 1 wraps around the first connecting member 6 and the first connecting member 6 wraps around the laser 3. Among them, the solid carrier 1 and the first connecting member 6, as well as the first connecting member 6 and the laser 3, can be connected by any one of mechanical connection, mechanical fit, or hot melt connection.

[0040] One end of the laser channel 4 connected to the first connecting member 6, the end of the first connecting member 6 extending into the laser channel 4, and the end of the laser head base 5 extending into the first connecting member 6 are all in the same plane.

[0042] Based on the structure of Embodiment 2, in Embodiment 3, as Figure 4As shown, the laser emission device for preventing fatigue driving further includes a hollow second connecting member 7 and a focusing lens structure member 8. By providing the focusing lens structure member 8, the laser emitted by the laser device 3 can be focused. At the same time, the focusing lens structure member 8 also has an adjustable function. By means of the focusing lens structure member 8, the size of the laser spot emitted by the laser device 3 can be changed. After the second connecting member 7 is connected to the focusing lens structure member 8, a connecting body is formed. After the connecting body is placed inside the laser channel 4 and connected to the solid carrier 1, a connecting structure is formed in which the solid carrier 1 covers the second connecting member 7 and the second connecting member 7 covers the focusing lens structure member 8. Among them, any one of mechanical connection, mechanical fit or thermal fusion connection can be adopted between the solid carrier 1 and the second connecting member 7 and between the second connecting member 7 and the focusing lens structure member 8; on this basis, the second connecting member 7 is arranged along the laser projection direction and in front of the first connecting member 6, and at the same time, the installation direction of the focusing lens structure member 8 is also the same as the laser projection direction.

[0043] At the end of the end of the second connecting member 7 adjacent to the first connecting member 6, there is a stepped portion 9 extending into the second connecting member 7, and the extended stepped portion 9 completely avoids or partially avoids the laser projection direction.

[0044] A tension spring 10 is further arranged between the focusing lens structure member 8 and the stepped portion 9. The arrangement of the tension spring 10 can prevent the focusing lens structure member 8 from slipping and unwinding threads, and ensure the focusing accuracy.

[0045] As Figure 5 shown, the first connecting member 6 and the second connecting member 7 are processed into an integral structural member.

Among them, the connection end of the light receiving member 11 and the laser channel 4 is connected by threads, and the length of the light receiving member 11 extending into the laser channel 4 can be adjusted movably.

[0048] At the end of the other end of the light receiving member 11, a cross-line lens 12 is provided for converting the point laser into a cross-shaped laser. By adjusting the length of the light receiving member 11 extending into the laser channel 4, the length of the linear laser can be adjusted, and by means of the focusing lens structure member 8, the width of the linear laser can be adjusted.

[0049] Along the laser projection direction, a lens holder 13 is further provided in front of the cross-line lens 12. A dust-proof lens 14 is further provided between the cross-line lens 12 and the lens holder 13. An anti-reflection film is plated on the dust-proof lens 14, and the anti-reflection film is an AR film.

[0050] A focusing lens 15 is further provided between the dust-proof lens 14 and the cross-line lens 12.

[0051] When the present invention is in use, the setting of the spherical or similar spherical solid carrier structure enables the present invention to achieve universal angle adjustment during installation and use. By providing a cross-line lens at the end of the light-receiving member, the point laser emitted by the laser can be converted into a linear laser. By adjusting the length of the light-receiving member extending into the laser channel, the length of the linear laser can be adjusted, and the width of the linear laser can be adjusted through the focusing lens structural member.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes.
