Problems solved by technology
[0003] The disadvantage of this is that it needs to be assembled to the frame as an additional intermediate step, and there are many assembly processes and the assembly process is complicated
The assembled frame and shell need to be fixed with screws again, so the mating surface between the frame and the shell is less, and the connection rigidity between the two is low
And if the frame moves inside the lidar, all lidar sub-modules attached to the frame will lose their position reference, resulting in a high risk of accuracy deviation
A lot of components are required, not only the additional configuration of the frame is required, but also additional fixed connection parts are required, resulting in an increase in the overall weight and volume of the device, which is not conducive to adapting to application environments such as aircraft and vehicles

Embodiment Construction
[0031] The implementation process of the technical solution of the present invention is described below in conjunction with specific embodiments, which are not intended to limit the present invention.
[0032] In order to simplify the structure, avoid setting the frame separately, and ensure the positioning, installation and protection of the sub-modules inside the laser radar, the invention discloses an integrated frame structure of the shell and frame applied to the laser radar, which combines the functions of the frame and the shell into one body. Through the functional transformation of the inner cavity of the shell, the present invention enables the positioning and installation of the laser radar sub-module to be realized directly by using the shell, and ensures that the internal structure of the laser radar is stable and compact, has a simple and efficient positioning frame, and can realize simple and fast installation way, while also improving the rigidity of the shell. ...

The invention discloses a shell-and-frame integrated structure and a laser radar with the same. At least two laser radar sub-modules are installed in the shell-and-frame integrated structure. The shell-and-frame integrated structure comprises a shell; a positioning supporting structure is arranged in an inner cavity of the shell, provides an installation positioning reference for the laser radar sub-modules, mechanically cooperates with the laser radar sub-modules and limits the spatial structure position relation between the laser radar sub-modules, and therefore, the shell can be used as a positioning frame of the laser radar. Through the structure of the invention, the integration of the frame and the shell is realized, and the shell plays a role in protecting and positioning the frame; and all the laser radar sub-modules are directly positioned and rooted in the shell, so that the rigidity of the shell is enhanced.
Description
technical field [0001] The invention relates to the structural design of laser radar, in particular to an integrated structure of shell and frame and laser radar with the structure. Background technique [0002] Existing laser radar products generally include at least one laser radar sub-module, which includes a circuit board, a scanning mirror, a laser transceiver module, and the like. All lidar sub-modules usually need to be installed on a frame for integrated assembly, and finally the integrated and assembled frame is loaded into the lidar casing. That is to say, all the components inside the lidar are completely fixed to the frame, and the frame as a whole is fixedly connected with the lidar casing. [0003] The disadvantage of this is that it needs to be assembled to the frame as an additional intermediate step, and there are many assembly processes and the assembly process is complicated. After the assembly, the frame and the shell need to be fixed with screws, so th...
