[0030] See also Figure 1 and Figure 2 The laser radar 1000 includes a module bracket 10, a transmitting assembly 20, a reflecting assembly 30, a limiting assembly 40, and a receiving assembly 50.

The module bracket 10, transmitting assembly 20, reflecting assembly 30, limiting assembly 40, and receiving assembly 50 are described in detail below.

[0031] For the above module bracket 10, Figure 2 and Figure 3 As shown, the module bracket 10 is provided with a mounting channel 10a, which allows the light generated by the emitting assembly 20 to flow. The module bracket 10 is provided with a first mounting groove 10b and a second mounting groove 10c. The first mounting groove 10b and the second mounting groove 10c are spaced apart, and the mounting channel 10a is located between the first mounting groove 10b and the second mounting groove 10c. The first mounting groove 10b and the second mounting groove 10c facilitate the installation of some components of the reflective assembly 30. Optionally, a spherical groove (not shown) is provided at the bottom of the first mounting groove 10b.

[0032] In some embodiments, the module bracket 10 is further provided with a first screw hole 101 , which is used to cooperate with the limiting plate 401 in the limiting assembly 40 , thereby fixing the limiting plate 401 relatively to the module bracket 10 .

The mounting groove 102 is located at one end of the mounting channel 10a. The mounting groove 102 is used for installing the emitting light source 201 in the emitting assembly 20.

[0034] In some embodiments, the module bracket 10 is provided with a limiting groove 103 connected to the installation channel 10a, and the limiting groove 103 is used to install the transmitting lens 202 in the transmitting assembly 20. The transmitting lens 202 is installed into the limiting groove 103 from the notch of the limiting groove 103. When the transmitting lens 202 needs to be replaced, the transmitting lens 202 can be removed from the notch of the limiting groove 103 for replacement.

[0036] For the above-mentioned transmitting component 20 and receiving component 50, as shown in FIG. Figure 2-Figure 4 As shown, the transmitting component 20 and the receiving component 50 are both installed on the module bracket 10. At least part of the transmitting component 20 is located at one end of the installation channel 10a. The receiving component 50 can convert the received optical signal into an electrical signal.

[0037] Specifically, the emitting assembly 20 includes an emitting light source 201 and an emitting lens 202. The emitting light source 201 is located at one end of the mounting channel 10a, and the emitting lens 202 is located at the other end of the mounting channel 10a. The emitting light source 201 and the emitting lens 202 are arranged opposite to each other. The emitting lens 202 is arranged at an inclined angle to the reflector 302 in the reflective assembly 30. The light generated by the emitting light source 201 flows through the emitting lens 202 and is transmitted to the reflector 302 in the reflective assembly 30, and is reflected by the reflector 302. Optionally, the emitting lens 202 is a convex lens.

[0038] In some embodiments, the emitting assembly 20 also includes a fixing plate 203, which is covered on the mounting groove 102. The fixing plate 203 is detachably connected to the module bracket 10. The fixing plate 203 can shield and protect the emitting light source 201 located in the mounting groove 102, and at the same time limit and fix the emitting light source 201 in the mounting groove 102.

[0039] In some embodiments, the emitting component 20 also includes a connecting piece 204, one end of which is electrically connected to the emitting light source 201, and the other end of which is electrically connected to the control circuit board 60. The connecting piece 204 is used to electrically connect the emitting component 20 and the control circuit board 60.

[0040] In some embodiments, the receiving component 50 includes a receiving lens 501, a filter 502 and a receiving chip 503. The receiving chip 503 is electrically connected to the control circuit board 60. The receiving lens 501, the filter 502 and the receiving chip 503 are arranged in sequence along the vertical direction. The receiving lens 501 receives the returned light, which is then filtered by the filter 502. Finally, the receiving chip 503 converts the optical signal into an electrical signal and outputs it to the control circuit board 60.

[0041] For the above-mentioned reflection component 30, as Figure 2-Figure 4 As shown, the reflective component 30 is installed on the module bracket 10. The reflective component 30 is located at the other end of the installation channel 10a. The reflective component 30 can receive the light emitted from the emitting lens 202. The reflective component 30 can be rotatably connected to the module bracket 10. The reflective component 30 and the emitting component 20 are arranged at an inclined angle. The reflective component 30 can be rotated at a preset angle relative to the emitting component 20.

[0042] Specifically, the reflective assembly 30 includes a reflective bracket 301 and a reflective member 302. The reflective member 302 is installed on the reflective bracket 301. The light flowing through the installation channel 10a flows toward the reflective member 302. The reflective member 302 is arranged at an inclined angle with respect to the emitting assembly 20. The reflective bracket 301 can be rotated relative to the emitting assembly 20 to adjust the inclination angle between the reflective member 302 and the emitting assembly 20. When the user needs to install the reflective member 302 to the ideal position, he only needs to rotate the reflective member 302. The reflector bracket 301 is moved to a preset position, so that the reflector 302 installed on the reflector bracket 301 can be rotated relative to the transmitting assembly 20, and then the reflector 302 can be rotated to an ideal position. After the reflector 302 is rotated to the preset position, the reflector bracket 301 can be limited by the limit assembly 40 to ensure that the reflector 302 and the module bracket 10 are in a relatively fixed state, thereby completing the installation of the reflector 302 and preventing the reflector 302 from deviating and affecting the normal operation of the laser radar. Optionally, the reflector bracket 301 can be rotated upward or downward relative to the module bracket 10, that is, to adjust the pitch angle of the reflector 302.

[0043] Specifically, the reflector bracket 301 includes a bracket body 3011, a first spherical arm 3012, and a second connecting arm 3013. One end of the first spherical arm 3012 is connected to one end of the bracket body 3011, and the other end of the first spherical arm 3012 is at least partially mounted in the spherical groove. The first spherical arm 3012 is rotatable in the spherical groove. One end of the second connecting arm 3013 is connected to the other end of the bracket body 3011, and the other end of the second connecting arm 3013 is mounted in the second mounting groove 10c. During the installation of the reflector bracket 301, to adjust the position of the reflector 302 on the bracket body 3011, the first spherical arm 3012 can be rotated so that the bracket body 3011 rotates toward the notch of the first mounting groove 10b, thereby adjusting the position of the reflector 302 on the bracket body 3011. Optionally, one end of the first spherical arm 3012 is connected to one end of the bracket body 3011 via a connecting rod 30121.

[0044] In some embodiments, a limiting column 30131 extends from the second connecting arm 3013 in a direction away from the module bracket 10 , and the limiting column 30131 is used to cooperate with the limiting plate 401 in the limiting assembly 40 to achieve limiting and fixing of the reflector bracket 301 .

[0045] It should be noted that the first spherical arm 3012 and the connecting rod 30121 form the rotating member in the present application. The rotating member is located on the side of the bracket body 3011 near the transmitting assembly 20. The rotating member is disposed in the first mounting groove 10b and can rotate within the first mounting groove 10b. The second connecting arm 3013 and the limiting post 30131 form the limiting member in the present application. The limiting member is located on the side of the bracket body 3011 near the transmitting assembly 20. The limiting member and the rotating member are spaced apart and are disposed in the second mounting groove 10c. It will be understood that to achieve the rotation of the reflector bracket 301, in some embodiments, only a single rotating member or multiple rotating members may be provided on the side of the bracket body 3011 near the transmitting assembly 20, as long as the reflector bracket 301 can rotate.

[0046] In some embodiments, the reflector bracket 301 is provided with a third mounting groove 301a and a through hole 301b connected to the third mounting groove 301a. The reflector 302 is installed in the third mounting groove 301a. The through hole 301b is arranged opposite to the other end of the mounting channel 10a. The light generated by the emitting light source 201 flows through the emitting lens 202, the through hole 301b, and the reflector 302 in sequence. Optionally, the reflector 302 is arranged obliquely in the third mounting groove 301a. The light generated by the emitting light source 201 is reflected by the reflector 302 and then emitted from the third mounting groove 301a in a vertical direction. The third mounting groove 301a is connected to the limiting groove 103 through the through hole 301b, and the emitting lens 202 is installed in the limiting groove 103.

[0047] In some embodiments, the reflective assembly 30 further includes a light baffle 303, one side of which abuts the module bracket 10, and the other side of which abuts the reflective bracket 301. The light baffle 303 is located in the gap between the module bracket 10 and the reflective bracket 301. The light generated by the emitting light source 201 is emitted from the emitting lens 202 on the module bracket 10 to the reflective member 302 on the reflective bracket 301. The provision of the light baffle 303 can prevent light from emitting from the gap between the module bracket 10 and the reflective bracket 301, thereby preventing light from being transmitted. Optionally, the light baffle 303 is light-blocking foam.

[0048] For the above-mentioned limiting component 40, as Figure 2 、 Figure 3 and Figure 5As shown, the limiting assembly 40 is detachably connected to the module bracket 10 and is used to limit and fix the reflector bracket 301. The limiting assembly 40 includes a limiting plate 401 and a first screw 402. The limiting plate 401 covers the notch of the first mounting slot 10b and the notch of the second mounting slot 10c. The limiting plate 401 abuts against the first spherical arm 3012. The limiting plate 401 is provided with a second screw hole 4011, which is arranged opposite to the first screw hole 101. One end of the first screw 402 passes through the second screw hole 4011 and is connected to the first screw hole 101. Because the limiting plate 401 abuts the first spherical arm 3012, the user can adjust the locking force of the first screw 402 by tightening or loosening the first screw 402, thereby adjusting the pressing force of the limiting plate 401 on the first spherical arm 3012.

[0049] In some embodiments, a first glue hole 4012 and a second glue hole 4013 are further provided on the limiting plate 401. The first glue hole 4012 is arranged opposite to the notch of the first mounting slot 10b, and the second glue hole 4013 is arranged opposite to the notch of the second mounting slot 10c. Part of the limiting column 30131 is inserted into the second glue hole 4013. After completing the position adjustment of the reflector 302, the user can inject glue through the first glue hole 4012 and the second glue hole 4013 to fix the first spherical arm 3012 and the module bracket 10, and fix the limiting column 30131 and the module bracket 10, thereby achieving the fixation between the reflector bracket 301 and the module bracket 10.

[0050] In some embodiments, limiting portions 4014 are extended from both ends of the limiting plate 401 , and limiting holes 40141 are provided on the limiting portions 4014 . The limiting blocks 104 are inserted into the limiting holes 40141 , thereby limiting and fixing the limiting plate 401 on the module bracket 10 .

[0051] In an embodiment of the present utility model, a module bracket 10, a transmitting component 20, a reflecting component 30 and a receiving component 50 are provided. The module bracket 10 is provided with a mounting channel 10a, the transmitting component 20 is mounted on the module bracket 10, at least part of the transmitting component 20 is located at one end of the mounting channel 10a, the light generated by the transmitting component 20 flows through the mounting channel 10a, the reflecting component 30 is mounted on the module bracket 10, the reflecting component 30 is located at the other end of the mounting channel 10a, the reflecting component 30 is rotatably connected to the module bracket 10, the reflecting component 30 and the transmitting component 20 are arranged at an inclined angle, and the reflecting component 30 can rotate relative to the transmitting component 20 at a preset angle. The receiving component 50 is installed on the module bracket 10. In this arrangement, since the reflecting component 30 can be rotated relative to the transmitting component 20, when the user needs to install the reflecting part 302 on the reflecting component 30 to the ideal position, that is, the relative ideal position between the transmitting component 20 and the reflecting component 30, it is only necessary to rotate the reflecting component 30 to the preset position, so as to adjust the relative position of the transmitting component 20 and the reflecting component 30, thereby completing the installation of the reflecting part 302 on the reflecting component 30, thereby avoiding the deviation of the reflecting component 30 and affecting the normal operation of the laser radar 1000.

[0052] The present invention also provides an embodiment of a robot, which includes the laser radar 1000 as described above. The function and structure of the laser radar 1000 can be found in the above embodiments and will not be described in detail here.
