[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0040] According to the first aspect of this application, referring to Figures 1 to 4, provides a laser radar motor, the laser radar motor includes: a base assembly 1 and a drive assembly 2, the base assembly 1 includes a base body 11 and a control board 12 fixed to the base body 11, the control board 12 is provided with a connecting hole 121; the drive assembly 2 includes a power piece 21 and a pin 22, the pin 22 is connected to the power piece 21, the pin 22 is inserted into the connecting hole 121, and the pin 22 is electrically connected to the power piece 21 and the control board 12.

[0041] The stator of the laser radar motor in the related technology is connected to the circuit board through the winding phase wire. The winding phase wire is an enameled wire and needs to be stripped and soldered on the circuit board. This connection method is relatively complicated, resulting in low assembly efficiency.

[0042] In this embodiment, the power component 21 is connected to the control board 12 via a pin 22. The power component 21 includes an iron core and a winding wound around the iron core. The winding is wound around the iron core by an automated winding machine to form the power component 21. The power component 21 is electrically connected to the pin 22. The power component 21 can then be directly plugged into the control board 12 via the pin 22, achieving an electrical connection between the power component 21 and the control board 12. There is no need for flying wires to connect the power component 21 and the control board 12, simplifying the connection process between the power component 21 and the control board 12, reducing assembly difficulty, and improving production efficiency and automation. In addition, the pin 22 is installed in the connection hole 121, which not only simplifies the assembly process, but also ensures that the power component 21 and the control board 12 are accurately aligned through the positioning of the pin 22, ensuring component position accuracy and improving the reliability of the lidar motor operation.

[0043] Reference Figures 1 to 4 In some embodiments, the driving component 2 also includes a rotating shaft 23, the power member 21 is fixedly mounted on the rotating shaft 23, one end of the rotating shaft 23 is fixedly connected to the base body 11, and the laser radar also includes a rotating component 3, the rotating component 3 is rotatably connected to the other end of the rotating shaft 23, the rotating component 3 includes a fixedly connected force-bearing member 31 and a lens 32, the force-bearing member 31 surrounds the power member 21, and the power member 21 is coupled with the force-bearing member 31 to drive the force-bearing member 31 to rotate, and the force-bearing member 31 drives the lens 32 to rotate for reflecting laser light for scanning.

[0044] In this embodiment, the power member 21 is fixed to the base body 11 via the rotating shaft 23, forming a stable driving core; the rotating assembly 3 is rotatably connected to the driving member via the rotating shaft 23, and the force-bearing member 31 is arranged around the power member 21, so that the electromagnetic force generated by the power member 21 acts on the force-bearing member 31, driving it to rotate the lens 32, thereby realizing the laser scanning function. At the same time, the base body 11, control panel 12, power member 21, rotating shaft 23, force-bearing member 31 and lens 32 in the laser radar motor are divided into a base assembly 1, a driving assembly 2 and a rotating assembly 3. Each component is modularly designed, and each module can be independently produced, assembled and debugged, which simplifies the overall production process and reduces assembly complexity. The modular structure also facilitates the replacement of damaged parts and improves maintenance efficiency.

[0045] Specifically, the base body 11 is provided with an axial hole, with the rotating shaft 23 having an interference fit therein. The base body 11 and the rotating shaft 23 are fixedly connected, and the rotating shaft 23 is positioned by the base body 11. Furthermore, the axial hole precisely positions the rotating shaft 23, ensuring accurate installation and minimizing vibration during operation. This ensures stable operation of the drive assembly 2 and the rotating assembly 3, thereby improving the overall operational reliability of the LiDAR motor. Furthermore, the control board 12 is fixedly connected to the base body 11 via fasteners.

[0046] Reference Figure 1 and Figure 2 In some embodiments, the rotating assembly 3 further includes a bracket 33 , which is rotatably connected to the rotating shaft 23 , the force-bearing member 31 is fixed to the inner peripheral side of the bracket 33 , and the lens 32 is fixedly mounted to the outer peripheral side of the bracket 33 .

[0047] In this embodiment, the bracket 33 serves as the supporting structure of the rotating component 3, and fixes the force-bearing member 31 and the lens 32 on the inner and outer sides respectively, forming a modular assembly structure. This reduces the number of parts and simplifies the assembly process, facilitates the precise positioning of the force-bearing member 31 and the power member 21, and makes the installation and positioning of the lens 32 more convenient, thereby improving the assembly efficiency and structural stability of the rotating component 3.

[0048] Specifically, in this application, the lenses 32 are provided with four sides, which are evenly distributed on the outer periphery of the bracket 33. The four lenses 32 are attached to the outer periphery of the bracket 33 by gluing or welding. In actual application, the number of lenses 32 can be set according to needs, which can be one or more than one side, preferably four.

[0049] Reference Figure 1 and Figure 3In some embodiments, the rotating assembly 3 further includes a code disk 34, which is fixedly mounted on the side of the bracket 33 facing the control board 12. The base assembly 1 further includes a sensor 13 fixed to the control board 12, and the sensor 13 is used to sense the code disk 34 to monitor the rotation angle of the base assembly 1.

[0050] In this embodiment, a code disk 34 and sensor 13 cooperate to monitor the angle of rotating assembly 3. As code disk 34 rotates with bracket 33, sensor 13 detects changes in the scale or signal on code disk 34, acquiring real-time information on the rotation angle of rotating assembly 3. This monitored data provides feedback for the scanning control of the lidar motor, enabling the system to adjust the power output of the driver based on the angle information, thereby adjusting the operation of rotating assembly 3 to meet preset requirements.

[0051] Reference Figure 1 In some embodiments, a mounting groove 333 is provided on a side of the bracket 33 facing the control board 12 , and the code wheel 34 is fixedly installed in the mounting groove 333 .

[0052] In this embodiment, a mounting slot 333, provided on the side of the bracket 33 facing the control board 12, provides a precise positioning structure for the code disc 34. By matching the shape of the mounting slot 333 with the code disc 34, the code disc 34 can be quickly and accurately installed, effectively avoiding positional deviations during installation and significantly improving the installation accuracy and assembly efficiency of the code disc 34. Furthermore, the mounting slot 333 provides a protective wrapping around the code disc 34, preventing damage to the code disc 34 from external collisions and ensuring stable operation of the code disc 34 during rotation angle monitoring, thereby ensuring the reliability and accuracy of the lidar motor angle monitoring system.

[0053] Reference Figures 1 to 4 In some embodiments, the rotating assembly 3 further includes a plurality of bearings 35 , and the bracket 33 is rotatably connected to the rotating shaft 23 via the plurality of bearings 35 , and the plurality of bearings 35 are located on the same side of the power member 21 .

[0054] In this embodiment, multiple bearings 35 provide multiple supports for the rotational connection between the bracket 33 and the rotating shaft 23, reducing shaking during rotation and improving the rotational stability of the rotating assembly 3. In addition, multiple bearings 35 are concentrated on the same side of the power member 21, which facilitates installation and maintenance of the bearings 35.

[0055] Reference Figure 1 、 Figure 5 and Figure 6 In some embodiments, a plurality of first annular grooves 331 are provided on the inner circumference of the bracket 33 , and the plurality of first annular grooves 331 are respectively located on the outer circumference of the plurality of bearings 35 . The first annular grooves 331 are used to be filled with glue to fix the bracket 33 and the outer ring of the bearing 35 .

[0056] In this embodiment, the first annular groove 331 and the glue securely connect the bracket 33 to the outer ring of the bearing 35. By filling the annular groove with glue, relative sliding between the outer ring of the bearing 35 and the inner circumference of the bracket 33 is effectively prevented, thereby enhancing the structural stability of the rotating assembly 3 and ensuring stable operation of the lidar motor.

[0057] Specifically, glue is pre-filled into the first annular groove 331 to ensure sufficient glue connection to ensure bonding strength. Glue can generally be anaerobic adhesive, structural adhesive, thermosetting adhesive, etc., and cured using the corresponding curing method. The above glue types are only used as examples and are not limited to the above glue types in actual application.

[0058] Reference Figure 1 、 Figure 5 and Figure 6 In some embodiments, a positioning ring 332 is provided on the inner circumference of the bracket 33, and the multiple bearings 35 include a first bearing 351 and a second bearing 352. Along the axial direction of the rotating shaft 23, the first bearing 351 and the second bearing 352 are respectively distributed on both sides of the positioning ring 332, one side of the positioning ring 332 abuts against the first bearing 351, and the other side of the positioning ring 332 abuts against the second bearing 352.

[0059] In this embodiment, the two axial sides of the positioning ring 332 serve as independent positioning references, allowing the machining accuracy of each side to be controlled independently. This allows for separate control of the axial assembly tolerances of the two bearings 35, preventing the tolerances of the two bearings 35 from interfering with each other and ensuring the precise axial positioning of the two bearings 35 on the shaft 23.

[0060] Reference Figure 1 、 Figure 7 and Figure 8 In some embodiments, a second annular groove 231 is provided on the outer peripheral side of the rotating shaft 23, and the distance between the second bearing 352 and the power member 21 is smaller than the distance between the first bearing 351 and the power member 21. The second annular groove 231 is located on the inner peripheral side of the second bearing 352. The second annular groove 231 is used to fill glue to fix the inner ring of the bearing 35 that connects the rotating shaft 23 and the second bearing 352.

[0061] In this embodiment, a second annular groove 231 is provided and filled with glue to achieve a fixed connection between the rotating shaft 23 and the inner ring of the bearing 35 of the second bearing 352. The glue enhances the connection strength and prevents the inner ring of the bearing 35 of the second bearing 352 and the rotating shaft 23 from rotating relative to each other, thereby ensuring the stability and reliability of power transmission.

[0062] Reference Figure 1 and Figure 3In some embodiments, the rotating assembly 3 further includes a movable retaining ring 24 and an elastic member 26. The movable retaining ring 24 is mounted on the rotating shaft 23 and is located on the side of the first bearing 351 away from the base assembly 1. Along the axial direction of the rotating shaft 23, the elastic member 26 is elastically connected between the movable retaining ring 24 and the first bearing 351, and the inner circumference of the first bearing 351 is clearance-fitted with the rotating shaft 23.

[0063] In this embodiment, the movable retaining ring 24 cooperates with the elastic member 26, and the elastic force of the wave spring is used to apply an axial preload to the first bearing 351, thereby eliminating the clearance of the bearing 35 and improving the smoothness and reliability of the motor operation; at the same time, the inner ring of the first bearing 351 is loosely matched with the rotating shaft 23, and combined with the elastic member 26, it can compensate for processing errors and thermal deformation, adapt to complex working conditions, and enhance structural stability.

[0064] Specifically, the elastic member 26 can be a wave spring, which provides axial elastic force and has a small axial dimension, making the lidar motor more compact. Furthermore, the rotating shaft 23 defines a fourth annular groove 234, into which the movable retaining ring 24 is removably mounted. A gasket 25 is disposed between the movable retaining ring 24 and the elastic member 26, with the wave spring abutting against the gasket 25.

[0065] Reference Figure 1 、 Figure 7 and Figure 8 In some embodiments, a fixed retaining ring 232 is provided on the outer peripheral side of the rotating shaft 23. Along the axial direction of the rotating shaft 23, one side of the fixed retaining ring 232 abuts against the other side of the second bearing 352, and the other side of the fixed retaining ring 232 abuts against one side of the power part 21.

[0066] In this embodiment, the axial sides of the fixed retaining ring 232 respectively axially position the second bearing 352 and the power part 21, which has a compact structure, reduces the displacement of the second bearing 352 and the power part 21 when subjected to axial force, and improves the stability of the laser radar motor during operation.

[0067] Reference Figure 1 、 Figure 7 and Figure 8 In some embodiments, along the axial direction of the rotating shaft 23 , the rotating shaft 23 is provided with a third annular groove 233 on both sides of the fixed retaining ring 232 .

[0068] In this embodiment, the rotating shaft 23 is provided with third annular grooves 233 on both sides of the fixed retaining ring 232, serving as tool relief grooves. The tool relief grooves provide space for the tool to retract during machining of the rotating shaft 23. This prevents machining errors on both sides of the fixed retaining ring 232 caused by tool retraction when machining other sections of the rotating shaft 23 to the vicinity of the fixed retaining ring 232. This ensures machining accuracy of the rotating shaft 23 and positioning accuracy of the fixed retaining ring 232.

[0069] Reference Figure 1 、 Figure 7 and Figure 8 In some embodiments, a ridge 235 is provided on the outer circumference of the rotating shaft 23 or the inner circumference of the power member 21 , and the rotating shaft 23 and the power member 21 are interference-fitted through the ridge 235 .

[0070] In this embodiment, the ridges 235 create an interference fit between the rotating shaft 23 and the power member 21, ensuring a stable connection between the rotating shaft 23 and the power member 21 and ensuring the structural stability of the lidar motor. The interference fit between the rotating shaft 23 and the power member 21 eliminates the need for other connecting parts, making assembly simple and convenient for production and processing.

[0071] Reference Figure 1 、 Figure 7 and Figure 8 In some embodiments, positioning holes 236 are respectively provided at the centers of both ends of the rotating shaft 23, and the positioning holes 236 are used for assembly positioning.

[0072] In this embodiment, the positioning holes 236 at each end of the rotating shaft 23 provide precise positioning references for assembly and commissioning of the LiDAR motor. During assembly, the positioning holes 236 cooperate with fixtures to ensure the coaxiality of the drive assembly 2 and other components (such as the base body 11 and the rotating assembly 3), thereby reducing assembly errors. During commissioning or maintenance, the positioning holes 236 facilitate the use of testing equipment to measure and calibrate the rotational accuracy of the rotating shaft 23, thereby improving the assembly efficiency and accuracy of the LiDAR motor.
