By disposing the buffer portion between the first abutting structure 70 and the blocking portion 20 provided in this embodiment, the force applied by the first abutting structure 70 to the blocking portion 20 can be buffered by the buffer portion, thereby effectively avoiding the phenomenon of stress concentration between the first abutting structure 70 and the blocking portion 20.

[0088] In an optional embodiment, the buffer portion provided in this embodiment includes an elastic buffer member, and the elastic buffer member provided in this embodiment is arranged on an end of the first abutting structure 70 close to the blocking body.

[0089] In an optional embodiment, the buffer portion provided in this embodiment includes an elastic buffer layer, and the elastic buffer layer provided in this embodiment is arranged on a side of the blocking body 21 away from the base assembly 30 .

[0090] In an optional embodiment, the elastic buffer layer provided in this embodiment is integrally formed with the blocking body 21 .

[0091] In summary, the implementation of the upper cover assembly, laser radar and mobile device provided in this embodiment has at least the following beneficial technical effects: the upper cover assembly provided in this embodiment, by covering the blocking part 20 on the first connecting hole 121 of the upper cover part 10, enables the first connecting hole 121 provided in this embodiment to be sealed by the blocking part 20, so that liquids and other substances in the external environment cannot enter the first connecting hole 121. When the upper cover assembly provided in this embodiment is installed on the base assembly 30 of the laser radar, since the upper cover assembly seals the first connecting hole 121 through the blocking part 20, it is difficult for liquids and other substances in the external environment to enter the interior of the laser radar through the first connecting hole 121, thereby effectively improving the sealing performance of the laser radar with the upper cover assembly provided in this embodiment.

[0092] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
