The invention relates to an automobile corner sensor which comprises a shell, a rotating pipe is arranged on the shell in a penetrating mode, the rotating pipe is rotationally connected with the shell, an angle detection device is arranged on the rotating pipe and located in the shell, and a dust removal mechanism is arranged in the shell. The dust removal mechanism comprises an air inlet pipe, the air inlet pipe is fixedly connected with the shell, air exhausted by the first exhaust pipe and the two second exhaust pipes acts on the main gear and the two auxiliary gears, dust on the main gear and the two auxiliary gears is blown away, and the dust removal efficiency is improved. Dust is prevented from being clamped between the main gear and the auxiliary gear to influence the rotation angle of the main gear driving the auxiliary gear, so that the angle detection precision is improved; dust in the shell is collected through the filter screen, dust attached to the circuit board is reduced, and the working reliability is improved; dust intercepted on the filter screen is separated from the filter screen through the inertia effect, the falling dust is collected through the collecting box, automatic cleaning of the filter screen is achieved, and the filter screen is prevented from being blocked.
本发明涉及一种汽车转角传感器,包括壳体,所述壳体上穿设有转动管,所述转动管与壳体转动连接,所述转动管上设置有角度检测装置,所述角度检测装置位于壳体内,所述壳体内设置有除尘机构;所述除尘机构包括进气管,所述进气管与外壳固定连接,本发明通过将第一排气管和两个第二排气管排出的空气作用到主齿轮和两个副齿轮上,将主齿轮和两个副齿轮上的灰尘吹离,避免灰尘卡入主齿轮和副齿轮之间而影响主齿轮驱动副齿轮的转动角度,进而提高角度检测精度;通过滤网收集壳体内的灰尘,减少电路板上灰尘的附着,提高工作可靠性;通过惯性作用使滤网上截留的灰尘与滤网分离,并通过收集箱收集掉落的灰尘,实现滤网的自动清洁,避免滤网堵塞。
