The invention discloses an automobile pedestrian warning device based on PWM signals. The device comprises an accelerator pedal mechanism, a sound production mechanism and a controller, and is characterized in that the controller is respectively connected with the accelerator pedal mechanism and the sound production mechanism through PWM signals; the accelerator pedal mechanism comprises a box body and an accelerator pedal, the controller is arranged in the box body, and the accelerator pedal is arranged at the top of the box body; the sound production mechanism comprises a shell and a loudspeaker installed in the shell, and further comprises a protective cleaning mechanism used for protecting the loudspeaker, the protective cleaning mechanism comprises a mesh enclosure, fixing blocks anda sliding groove, and the fixing blocks are symmetrically arranged at the top of the shell. The beneficial effects of the device are that the designed protective cleaning mechanism facilitates the protection of the loudspeaker in the shell, and the mesh enclosure can be pulled out for cleaning when dust is accumulated on the surface of the mesh enclosure; and through the designed limiting mechanism, the convenience of penetrating in and out of the wire is improved through a wire penetrating column, and the wire is convenient to use.

    本发明公开了一种基于PWM信号的汽车行人警示装置,包括油门踏板机构、发声机构、控制器,所述控制器分别与油门踏板机构和发声机构通过PWM信号连接;所述油门踏板机构包括箱体和油门踏板,所述箱体的内部设置有控制器,且箱体的顶部设置有油门踏板;所述发声机构包括壳体以及安装在壳体内的扬声器,还包括用于对所述扬声器进行防护的防护清洁机构,所述防护清洁机构包括网罩、固定块、滑槽,所述固定块对称设置于壳体的顶部;本发明的有益效果是:通过设计的防护清洁机构,便于对壳体内的扬声器进行防护,当网罩表面积灰时,可将网罩抽拉出进行清洁;通过设计的限位机构,利用穿线柱增加了导线穿入穿出的便利性,便于导线的使用。
