[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0025] See also Figures 1 to 3As shown, according to an embodiment of the present application, a new laser radar structure is provided, including a first substrate 200 and a second substrate 300, the first substrate 200 has a first mounting surface, the first mounting surface is used to install the light-emitting component, the second substrate 300 has a second mounting surface, the second mounting surface is used to install the receiving component, and the height difference between the first mounting surface and the second mounting surface is adjustable.

[0026] By setting up a new laser radar structure including a first substrate 200 and a second substrate 300, the light-emitting component and the receiving component can be installed on different circuit boards. At the same time, by setting an adjustable height difference between the first mounting surface on the first substrate 200 and the second mounting surface on the second substrate 300, lenses of different heights can be adapted to achieve the purpose of being compatible with lenses of different specifications within a certain range, so that the laser radar can be applied to different scenarios and quickly iterated.

[0027] The laser radar includes a housing 100, which has a receiving space inside. The light emitting component and the receiving component are arranged in the receiving space of the housing 100. The housing 100 provides a stable installation position for the light emitting component and the receiving component.

[0028] The laser radar further includes a cover plate, which is connected to the housing 100 and is used to seal the receiving space. By providing the cover plate, the light emitting component and the receiving component can be prevented from being contaminated by dust and dirty water.

[0029] In one embodiment, the housing 100 is a rectangular body with one side open, and the cover is rectangular. In another embodiment, both the housing 100 and the cover are triangular bodies with one side open. The inclined surface of the housing 100 and the inclined surface of the cover meet to form a storage space for the light-emitting component and the receiving component. In the embodiment of the present application, both the housing 100 and the cover are right triangle bodies with one side open.

[0030] Specifically, the cover includes a bottom surface, which is parallel to the first substrate 200 and the second substrate 300. A first opening is provided on the bottom surface at a position relative to the light-emitting component, and the first opening is provided so that the light emitted by the light-emitting component can be irradiated to the object to be detected through the first opening; a second opening is also provided on the bottom surface at a position relative to the receiving component, and the second opening is provided so that the reflected light from the object to be detected can be emitted into the receiving component through the second opening.

[0031] The first substrate 200 is disposed on the side of the light-emitting component facing away from the first opening. The side of the first substrate 200 closer to the first opening forms a first mounting surface, on which the light-emitting component is disposed. The second substrate 300 is disposed on the side of the receiving component facing away from the second opening. The side of the second substrate 300 closer to the second opening forms a second mounting surface, on which the receiving component is disposed. In this application, the provision of the first substrate 200 and the second substrate 300 provides a stable mounting position for the light-emitting component and the receiving component.

[0032] Specifically, the first substrate 200 and the second substrate 300 are slidably disposed in the housing 100 so that the height difference between the first mounting surface and the second mounting surface is adjustable to adapt to the lens heights of the transmitting and receiving components with different height differences.

[0033] As an embodiment, the heights of the first substrate and the second substrate can be set to be the same or set as one, a first pad is set between the first substrate 200 and the light-emitting chip, and a second pad is set between the second substrate 300 and the receiving chip; the heights of the first pad and the second pad are different, so that a height difference is formed between the first mounting surface and the second mounting surface.

[0034] As another embodiment, a slide rail is provided on the inner wall of the shell 100, and the slide rail extends in a direction perpendicular to the first substrate 200 and the second substrate 300. The outer edges of the first substrate 200 and the second substrate 300 are connected with a slider, and the slider extends in the same direction as the slide rail. The slider is arranged in the slide rail and can move along the extension direction of the slide rail to adjust the height difference between the first substrate 200 and the second substrate 300, that is, the height difference between the first mounting surface and the second mounting surface.

[0035] As another embodiment, a partition is provided in the accommodating space of the shell 100, and the first substrate 200 and the second substrate 300 are provided on both sides of the partition and are respectively slidably connected to the partition to adjust the height difference between the first substrate 200 and the second substrate 300, that is, the height difference between the first mounting surface and the second mounting surface. It is understandable that in order to improve the accuracy of the detection results, the transmitting end of the light-emitting component and the receiving end of the receiving component should be located in the same plane. In the present application, the height difference between the first mounting surface and the second mounting surface can be adjusted for lenses of different heights to ensure that the transmitting end of the light-emitting component and the receiving end of the receiving component should be located in the same plane, so as to achieve the purpose of compatibility with lenses of different specifications within a certain range.

[0036] Among them, in the examples of this application, see Figure 1As shown, a first slide rail 101 is provided on the inner wall of the shell 100 at a position relative to the first substrate 200, and the first slide rail 101 extends along the direction of light propagation. A first slider 103 is slidably provided in the first slide rail 101, and a first connecting rod 107 is provided on the side of the first slider 103 close to the first substrate 200. A first connecting plate 105 is provided on the end of the first connecting rod 107 away from the first slider 103, and the first connecting plate 105 is relatively fixed to the first substrate 200; a second slide rail 102 is also provided on the inner wall of the shell 100 at a position relative to the second substrate 300, and the second slide rail 102 extends in the same direction as the first slide rail 101, and a second slider 104 is slidably provided in the second slide rail 102, and a second connecting rod 108 is provided on the side of the second slider 104 close to the second substrate 300, and a second connecting plate 106 is provided on the end of the second connecting rod 108 away from the second slider 104, and the second connecting plate 106 is relatively fixed to the second substrate 300.

[0037] Specifically, in the examples of this application, see Figure 1 As shown, one end of the first connecting rod 107 away from the first slider 103 passes through the first connecting plate 105 in a direction perpendicular to the first connecting plate 105, and is threadedly connected to a first handle, so that the first connecting plate 105 can be pressed against the inner wall of the shell by screwing the first handle, so that the first substrate 200 is fixed at the first height; the end of the second connecting rod 108 away from the second slider 104 passes through the second connecting plate 106 in a direction perpendicular to the second connecting plate 106, and is threadedly connected to a second handle, so that the second connecting plate 106 can be pressed against the inner wall of the shell by screwing the second handle, so that the second substrate 300 is fixed at the second height.

[0038] When the first substrate 200 is fixed at the first height and the second substrate 300 is fixed at the second height, the emitting end of the light emitting component and the receiving end of the receiving component are coplanar.

[0039] In some possible implementations provided in this application, see Figure 3 As shown, the light-emitting component includes a light-emitting chip 400 and a light-emitting lens 500. The light-emitting chip 400 is used to emit light. The light-emitting lens 500 is arranged on the side of the light-emitting chip 400 away from the first mounting surface. The light-emitting lens 500 is used to convert the light emitted by the light-emitting chip 400 into parallel light.

[0040] By setting up the light-emitting lens 500, the light emitted by the light-emitting chip 400 can be converted into parallel light. The parallel light is irradiated perpendicularly to the bottom surface, which can avoid the influence of uneven light emission or light tilt of the light-emitting chip 400 on the intensity of light received by the receiving component. In addition, the light is focused by the light-emitting lens 500, so that the light of the light-emitting chip 400 is fully utilized.

[0041] The light emitting chip 400 is disposed on the first substrate 200 . The light emitting chip 400 may be a transmitting circuit board. The transmitting circuit board has a light source disposed toward the first opening.

[0042] Specifically, the light emitting chip 400 and the first substrate 200 may be connected by adhesive connection.

[0043] The light-emitting lens 500 is disposed on a side of the light-emitting chip 400 away from the first substrate 200 . The light-emitting lens 500 may be a light-guiding lens that adjusts the light emitted by the light-emitting chip 400 .

[0044] Specifically, the light emitted by the light emitting chip 400 passes through the light emitting lens 500 and reaches the object to be detected. The light emitting lens 500 is used to convert multi-angle light into parallel light.

[0045] In some possible implementations provided in this application, see Figure 3 As shown, the light emitting assembly further includes a first base 600 , which is disposed above the light emitting chip 400 . A first mounting hole 601 is defined on the first base 600 , and the light emitting lens 500 is disposed in the first mounting hole 601 .

[0046] By providing a first base 600 and opening a first mounting hole 601 on the first base 600, so that the light-emitting lens 500 is disposed in the first mounting hole 601, it is ensured that the light emitted by the light-emitting chip 400 is transmitted toward the light-emitting lens 500, and the light emitted by the light-emitting chip 400 is prevented from propagating between the bottom surface and the first substrate 200, thereby affecting the accuracy of the receiving component in receiving the reflected light.

[0047] The first base 600 can be made of opaque material such as black polyurethane to prevent light from penetrating.

[0048] This application does not make any further limitations.

[0049] Specifically, the first base 600 is disposed between the first substrate 200 and the bottom surface, and the first base 600 is connected to the first substrate 200 , and the connection method thereof may be an adhesive connection, etc., which is not further limited in this application.

[0050] Among them, a first mounting hole 601 is opened on the first base 600 at the light source position relative to the light emitting chip 400. The first mounting hole 601 passes through the first base 600 in a direction perpendicular to the first substrate 200. The light emitting lens 500 can be embedded in the first base 600 through the first mounting hole 601.

[0051] Specifically, a light-emitting cavity is formed within the first mounting hole 601, which serves as a propagation space for light emitted by the light-emitting chip 400. In the present application, by providing the first mounting hole 601 on the first base 600 and disposing the light-emitting lens 500 within the first mounting hole 601, all light emitted by the light-emitting chip 400 can pass through the light-emitting lens 500 to reach the object to be detected for reflection, thereby improving the intensity of the reflected light. At the same time, this prevents light emitted by the light-emitting chip 400 from entering the receiving component and directly reaching the receiving chip 800 without passing through the receiving lens 900, thereby affecting the detection results, thereby improving the accuracy of the detection results.

[0052] In the above embodiment, see Figure 1 and Figure 3 As shown, a first adjusting member 700 is connected to the hole wall of the first mounting hole 601, and the first adjusting member 700 is perpendicular to the outer edge of the light-emitting lens 500. The length of the first adjusting member extending out of the hole wall of the first mounting hole 601 in the centripetal direction of the first mounting hole 601 is adjustable.

[0053] By arranging a first adjusting member 700 on the hole wall of the first mounting hole 601 and extending the first adjusting member 700 out of the hole wall of the first mounting hole 601 in the centripetal direction of the first mounting hole 601, the length of the first adjusting member 700 can be adjusted to adapt to light-emitting lenses 500 of different diameters, thereby achieving the purpose of further compatibility with lenses of different specifications within a certain range, so that the laser radar can be applied to different scenarios and quickly iterated.

[0054] Among them, the first mounting hole 601 can be a cylindrical through hole, and a first adjusting member 700 is connected to the hole wall of the first mounting hole 601. The first adjusting member 700 is perpendicular to the outer edge of the light-emitting lens 500, and the length of the first adjustment member extending out of the hole wall of the first mounting hole 601 in the centripetal direction of the first mounting hole 601 is adjustable. The first adjusting member 700 can abut the outer edge of the light-emitting lens 500 to achieve the purpose of locking the light-emitting lens 500 and preventing the light-emitting lens 500 from shaking in the first mounting hole 601.

[0055] The outer edge of the light emitting lens 500 may be a portion of the outer periphery of the light emitting lens 500. The first adjusting member 700 being perpendicular to the outer edge of the light emitting lens 500 indicates that the first adjusting member 700 and the outer periphery tangent of the light emitting lens 500 are perpendicular to each other.

[0056] The centripetal direction of the first mounting hole 601 may be a direction from a point on the hole wall of the first mounting hole 601 to the center of the first mounting hole 601 .

[0057] It is understood that the actual inner diameter of the first mounting hole 601 is the difference between the diameter of the first mounting hole 601 and the length of the hole wall of the first mounting hole 601 extending in the centripetal direction of the first mounting hole 601. Because the length of the hole wall of the first mounting hole 601 extending in the centripetal direction of the first mounting hole 601 is adjustable, the actual inner diameter of the first mounting hole 601 can be adjusted, thereby adapting to light-emitting lenses 500 of different diameters, achieving compatibility with lenses of different specifications within a certain range, and facilitating the application of the LiDAR in different scenarios and rapid iteration.

[0058] Specifically, as one embodiment, the first adjustment member 700 is a spring. When the spring is pressed, the actual inner diameter of the first mounting hole 601 increases to accommodate a light-emitting lens 500 with a large diameter. When the spring is released, the actual inner diameter of the first mounting hole 601 decreases to accommodate a light-emitting lens 500 with a small diameter. As another embodiment, the first adjustment member 700 is a bolt. A bolt hole is provided on the wall of the first mounting hole 601 along the radial direction of the first mounting hole 601, and the bolt is disposed in the bolt hole. When the bolt is tightened to move the bolt away from the light-emitting lens 500, the actual inner diameter of the first mounting hole 601 increases to accommodate a light-emitting lens 500 with a large diameter. When the bolt is tightened to move the bolt toward the light-emitting lens 500, the actual inner diameter of the first mounting hole 601 decreases to accommodate a light-emitting lens 500 with a small diameter. In the embodiment of the present application, the first adjustment member 700 is a bolt. Compared to a spring, the bolt can fix the light-emitting lens 500 in the radial direction of the first mounting hole 601, thereby preventing the light-emitting lens 500 from shaking within the first mounting hole 601. It should be noted that the spring and the bolt can also be used in combination. The wall of the first mounting hole 601 can be provided with both a spring and a bolt. The spring is used to position the light-emitting lens 500, and the bolt is used to fix the light-emitting lens 500.

[0059] In the above embodiment, at least three first adjusting members 700 are provided, and the at least three first adjusting members 700 are evenly arranged along the circumferential direction of the first mounting hole 601 .

[0060] Among them, three, four or five first adjustment members 700 can be provided, etc., so as to limit the light-emitting lens 500 in the circumferential direction, and this application does not make further limitations.

[0061] Specifically, in the embodiment of the present application, three first adjustment members 700 are provided, and the three first adjustment members 700 are evenly arranged along the circumference of the first mounting hole 601. In the present application, by providing three first adjustment members 700 and evenly arranging the three first adjustment members 700 along the circumference of the first mounting hole 601, the light-emitting lens 500 can be limited in the circumferential direction, thereby ensuring the concentricity of the light-emitting lens 500 and the first mounting hole 601, thereby improving the accuracy of the detection results.

[0062] It should be noted that when bolts and springs are provided on the hole wall of the first mounting hole 601 at the same time, three bolts and three springs are provided. In the circumferential direction of the first mounting hole 601 , the three bolts and the three springs are alternately arranged.

[0063] In some possible embodiments provided in the present application, the receiving component includes a receiving chip 800 and a receiving lens 900. The receiving chip 800 is used to receive reflected light. The receiving lens 900 is arranged on the side of the receiving chip 800 away from the second mounting surface. The receiving lens 900 is used to converge the reflected light into parallel light.

[0064] By providing the receiving lens 900 , the reflected light can be converged into parallel light, so that the receiving chip 800 can receive the parallel light, thereby making the reflected light intensity value obtained by the receiving chip 800 more accurate, thereby improving the accuracy of the detection result.

[0065] The receiving chip 800 is disposed on the second substrate 300 . The receiving chip 800 may specifically be a receiving circuit board, and the receiving circuit board is disposed toward the first opening.

[0066] Specifically, the receiving chip 800 and the second substrate 300 may be connected by adhesive connection.

[0067] The receiving lens 900 is disposed on a side of the receiving chip 800 away from the second substrate 300 . The receiving lens 900 may specifically be a light-guiding lens, which adjusts the reflected light from the object to be detected.

[0068] Specifically, the reflected light from the object to be detected reaches the receiving chip 800 through the receiving lens 900. The receiving lens 900 is used to converge the reflected light into parallel light. The receiving chip 800 receives the parallel light, and the obtained reflected light intensity value is more accurate.

[0069] In some possible implementations provided in this application, see Figure 3 As shown, the receiving assembly further includes a second base 1000 , which is disposed above the receiving chip 800 . A second mounting hole 1001 is defined on the second base 1000 , and the receiving lens 900 is disposed in the second mounting hole 1001 .

[0070] By setting a second base 1000 and opening a second mounting hole 1001 on the second base 1000, so that the receiving lens 900 is set in the second mounting hole 1001, it can be ensured that the reflected light passing through the receiving chip 800 is transmitted toward the receiving chip 800, and the received light is prevented from propagating between the bottom surface and the second substrate 300, affecting the accuracy of the receiving chip 800 in receiving the reflected light.

[0071] Among them, the second base 1000 can be made of opaque materials such as black polyurethane to prevent light from passing through, and this application does not make further limitations.

[0072] Specifically, the second base 1000 is disposed between the second substrate 300 and the bottom surface of the shell 100 , and the second base 1000 is connected to the second substrate 300 , and the connection method thereof may be an adhesive connection, etc., which is not further limited in this application.

[0073] Among them, a second mounting hole 1001 is opened on the second base 1000 at a position relative to the receiving chip 800. The second mounting hole 1001 passes through the second base 1000 in a direction perpendicular to the bottom surface. The receiving lens 900 can be embedded in the second base 1000 through the second mounting hole 1001.

[0074] Specifically, a light-receiving cavity is formed within the second mounting hole 1001, which serves as a propagation space for reflected light. In this application, by providing the second mounting hole 1001 on the second base 1000 and positioning the receiving lens 900 within the second mounting hole 1001, the emitted light is completely transmitted through the receiving lens 900 to the receiving chip 800 for detection, thereby increasing the intensity of the reflected light. This also prevents the reflected light from entering the light-emitting component and affecting the detection results, thereby improving the accuracy of the detection results.

[0075] In the above embodiment, see Figure 1 and Figure 3 As shown, a second adjusting member 1100 is connected to the hole wall of the second mounting hole 1001, and the second adjusting member 1100 is perpendicular to the outer edge of the receiving lens 900. The length of the second adjusting member 1100 extending out of the hole wall of the second mounting hole 1001 along the centripetal direction of the second mounting hole 1001 is adjustable.

[0076] By arranging a second adjustment member 1100 on the hole wall of the second mounting hole 1001 and making the second adjustment member extend out of the hole wall of the second mounting hole 1001 in the centripetal direction of the second mounting hole 1001, the length of the second adjustment member 1100 can be adjusted to adapt to receiving lenses 900 of different diameters, thereby achieving the purpose of further compatibility with lenses of different specifications within a certain range, so that the laser radar can be applied to different scenarios and quickly iterated.

[0077] Among them, the second mounting hole 1001 can be a cylindrical through hole, and a second adjusting member 1100 is connected to the hole wall of the second mounting hole 1001. The second adjusting member 1100 is perpendicular to the outer edge of the receiving lens 900, and the length of the second adjustment member extending out of the hole wall of the second mounting hole 1001 in the centripetal direction of the second mounting hole 1001 is adjustable. The second adjusting member 1100 can abut the outer edge of the receiving lens 900 to achieve the purpose of locking the receiving lens 900 and preventing the receiving lens 900 from shaking in the second mounting hole 1001.

[0078] The outer edge of the receiving lens 900 may be a portion of the outer periphery of the receiving lens 900. The second adjusting member 1100 being perpendicular to the outer edge of the receiving lens 900 indicates that the second adjusting member 1100 and the outer periphery tangent of the receiving lens 900 are perpendicular to each other.

[0079] The centripetal direction of the second mounting hole 1001 may be a direction from a point on the hole wall of the second mounting hole 1001 to the center of the second mounting hole 1001 .

[0080] It is understood that the actual inner diameter of the second mounting hole 1001 is the difference between the diameter of the second mounting hole 1001 and the length of the second adjustment extending from the hole wall of the second mounting hole 1001 in the centripetal direction of the second mounting hole 1001. Because the length of the second adjustment extending from the hole wall of the second mounting hole 1001 in the centripetal direction of the second mounting hole 1001 is adjustable, the actual inner diameter of the second mounting hole 1001 can be adjusted, thereby adapting to receiving lenses 900 of different diameters, achieving compatibility with lenses of different specifications within a certain range, and facilitating the application of the LiDAR in different scenarios and rapid iteration.

[0081] Specifically, in one embodiment, the second adjusting member 1100 is a spring. When the spring is pressed, the actual inner diameter of the second mounting hole 1001 increases to accommodate a larger diameter receiving lens 900. When the spring is released, the actual inner diameter of the second mounting hole 1001 decreases to accommodate a smaller diameter receiving lens 900. In another embodiment, the second adjusting member 1100 is a bolt. A bolt hole is defined in the wall of the second mounting hole 1001 along the radial direction of the second mounting hole 1001, and the bolt is disposed within the bolt hole. When the bolt is tightened to move away from the receiving lens 900, the actual inner diameter of the second mounting hole 1001 increases to accommodate a larger diameter receiving lens 900. When the bolt is tightened to move toward the receiving lens 900, the actual inner diameter of the second mounting hole 1001 decreases to accommodate a smaller diameter receiving lens 900. In the embodiment of the present application, the second adjustment member 1100 is a bolt. Compared to a spring, the bolt can fix the receiving lens 900 in the radial direction of the second mounting hole 1001, thereby preventing the receiving lens 900 from shaking within the second mounting hole 1001. It should be noted that the spring and the bolt can also be used in combination. The wall of the second mounting hole 1001 can be provided with both a spring and a bolt. The spring is used to position the receiving lens 900, and the bolt is used to fix the receiving lens 900.

[0082] In the above embodiment, at least three second adjusting members 1100 are provided, and the at least three second adjusting members 1100 are evenly arranged along the circumferential direction of the second mounting hole 1001 .

[0083] Among them, the second adjustment members 1100 can be provided in three, four or five numbers, etc., so as to limit the receiving lens 900 in the circumferential direction, and this application does not make further limitations.

[0084] Specifically, in the embodiment of the present application, three second adjustment members 1100 are provided, and the three second adjustment members 1100 are evenly arranged along the circumferential direction of the second mounting hole 1001. In the present application, by providing three second adjustment members 1100 and evenly arranging the three second adjustment members 1100 along the circumferential direction of the second mounting hole 1001, the receiving lens 900 can be limited in the circumferential direction, thereby ensuring the concentricity of the receiving lens 900 and the second mounting hole 1001, thereby improving the accuracy of the detection results.

[0085] It should be noted that when bolts and springs are provided on the hole wall of the second mounting hole 1001 at the same time, three bolts and three springs are provided. In the circumferential direction of the second mounting hole 1001, the three bolts and the three springs are alternately arranged.

[0086] The new laser radar structure provided in the embodiments of the present application is configured to include a first substrate 200 and a second substrate 300, so that the light-emitting component and the receiving component can be installed on different circuit boards. At the same time, by setting an adjustable height difference between the first mounting surface on the first substrate 200 and the second mounting surface on the second substrate 300, lenses of different heights can be adapted to achieve compatibility with lenses of different specifications within a certain range, so that the laser radar can be applied to different scenarios and quickly iterated.

[0087] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0088] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application. The above are merely preferred embodiments of the present application. It should be noted that those skilled in the art may make various improvements and variations without departing from the technical principles of the present application, and such improvements and variations shall also be considered within the scope of protection of the present application.
