Abstract
Description
Technical Field
[0001] The utility model relates to a novel lidar turntable device, belonging to the field of radar. Background Art
[0002] Currently, the short-axis outer frame and the long-axis outer frame of the commonly used radar turntables on the market are both square structures, and are fixed to each other by screws between square plates. Although there are sealing rings to prevent wind sand and rain, due to the non-integral structure, the connection gaps between the square plates are relatively large, resulting in the sealing performance not reaching the ideal effect, thus causing wind sand and rain to enter and shortening the service life of the turntable. In addition, regular maintenance is required, increasing the use cost. There are also bearings fixed on the outer circle of the long axis
[0003] All use ordinary ball bearings. As time goes by and wind sand, rain and moisture enter, the rotational performance of the bearings is greatly reduced, resulting in jamming of the long axis rotation and motor locking, making the turntable unable to work properly. Only by constantly replacing the bearings, on the one hand, it affects the normal use requirements and also increases the output cost. Content of the Utility Model
[0004] To overcome the defects of the prior art, the utility model provides a novel lidar turntable device. The technical solution of the utility model is as follows:
[0005] A novel lidar turntable device includes a base, a longitudinal sleeve outer frame and a transverse sleeve outer frame. A housing flange is installed on the base. One end of the longitudinal sleeve outer frame is connected to the base at the housing flange. The other end of the longitudinal sleeve outer frame forms a bent end, and the bent end of the longitudinal sleeve outer frame is connected to one end of the transverse sleeve outer frame through a connecting flange. The other end of the transverse sleeve outer frame is bent and installed with a front sealing mirror cover. A rear sealing mirror cover is installed at the bent part of the longitudinal sleeve outer frame. A longitudinal rotating assembly is installed inside the longitudinal sleeve outer frame, and a transverse rotating assembly is installed inside the transverse sleeve outer frame.
[0006] The longitudinal rotating assembly includes a longitudinal sleeve, a first skeleton oil seal, a first oil nozzle and a first crossed roller bearing. The longitudinal sleeve is rotatably installed in the longitudinal sleeve outer frame through the first crossed roller bearing. The first skeleton oil seal is also sleeved on the periphery of the longitudinal sleeve near the first crossed roller bearing. The oil inlet of the first oil nozzle is located outside the longitudinal sleeve outer frame, and the oil outlet of the first oil nozzle extends to the first crossed roller bearing.
[0007] The described horizontal rotation assembly includes a horizontal sleeve, a second skeleton oil seal, a second oil nozzle, and a second crossed roller bearing. The horizontal sleeve is rotatably installed within the outer frame of the horizontal sleeve through the second crossed roller bearing. The second skeleton oil seal is also sleeved around the periphery of the horizontal sleeve near the second crossed roller bearing. The inlet of the second oil nozzle is located outside the outer frame of the horizontal sleeve, and the outlet of the second oil nozzle extends to the position of the second crossed roller bearing.
[0008] The bent section of the outer frame of the horizontal sleeve is perpendicular to the outer frame of the horizontal sleeve.
[0009] The housing flange is connected to the base by screws.
[0010] The advantages of the present utility model are as follows: The overall sealing performance is enhanced, and the wind resistance coefficient is relatively low, which improves the rotation efficiency of the turntable. Since it is a one-piece structure for sealing, the performance of blocking sand and rain is further enhanced, so the service life of the turntable is greatly improved. Due to the use of crossed roller bearings, the service life and rotational performance of the crossed roller bearings are greatly improved, which enhances the service life and performance of the turntable and the motor. Moreover, an oil nozzle is added to the outer diameter of the bearing for lubricating and cleaning the interior of the bearing in the later stage, eliminating the need to disassemble the turntable to remove the bearing for maintenance. This is convenient and fast while ensuring the integrity of the turntable, reducing the output cost. The skeleton oil seal added to the crossed roller bearing mainly prevents sand and rain from entering the internal structure, enhancing the sealing performance, further improving the protection of the motor, and increasing the service life of the turntable.

[0018] The longitudinal rotation assembly includes a longitudinal sleeve 10, a first skeleton oil seal 12, a first oil nozzle 8 and a first crossed roller bearing 9. The longitudinal sleeve 10 is rotatably installed in the longitudinal sleeve outer frame 2 through the first crossed roller bearing 9.

The transverse sleeve 11 is rotatably installed in the transverse sleeve outer frame through the second crossed roller bearing 13.

[0022] The working principle of the present utility model is:
[0023] The longitudinal rotation assembly includes a longitudinal sleeve 10, a first skeleton oil seal 12, a first oil nozzle 8, and a first crossed roller bearing 9. The longitudinal sleeve 10 rotates within the longitudinal sleeve outer frame 2 through the first crossed roller bearing 9.

The second skeleton oil seal 14 functions as a seal, and the second oil nozzle is responsible for supplying lubricating oil to the bearing.
[0025] The longitudinal rotation assembly allows the lidar to rotate longitudinally (vertically) to detect targets at different heights.
[0026] The transverse rotation assembly allows the lidar to rotate transversely (horizontally) to detect targets in different directions.
[0027] The lidar is installed within the longitudinal sleeve 10 and the transverse sleeve 11, and realizes omnidirectional rotation detection through the rotation assemblies in two directions.
[0028] The first oil nozzle 8 and the second oil nozzle supply lubricating oil to the crossed roller bearings to ensure smooth rotation and reduce wear. By controlling the rotation of the longitudinal and transverse rotation assemblies, the lidar can perform 360-degree omnidirectional scanning and detection of the surrounding environment.
