[0013] 2. In this utility model, if the driver leans out of the vehicle, triggering an infrared sensor grating signal, the alarm will continue to sound a voice alarm, reminding the driver to correct their driving posture. When the driver resumes the correct driving posture, the infrared sensor grating signal disappears and the voice alarm stops. The two gratings are the transmitting and receiving ends respectively. When the receiving end cannot sense the infrared light, the alarm sounds. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figures 1 to 5The utility model provides a technical solution: a cab offside alarm device, comprising a guide rail 1, a guide groove 101 opened inside the guide rail 1, a horizontal screw 2 rotatably arranged inside the guide groove 101, nut blocks 3 are threadedly sleeved on both ends of the screw 2, the bottom end of the nut block 3 passes through the guide groove 101 and is detachably installed with a grating 11, a bracket 4 is fixedly connected to the inside of the guide groove 101, the screw 2 is rotatably inserted inside the bracket 4, an alarm 13 and a main controller 14 are fixedly installed on the front side wall of the guide rail 1, and the main controller 14 is electrically connected to the alarm 13 and the receiving end of the grating 11.

[0022] The two gratings 11 serve as the transmitter and receiver, respectively. When the receiver loses infrared sensing, an alarm sounds. If the driver leans out of the vehicle, triggering the infrared grating signal, the main controller 14 transmits the signal to the alarm 13, which then emits a continuous voice alarm to remind the driver to correct their driving posture. Once the driver resumes the correct driving posture, the infrared sensing signal disappears, and the voice alarm stops.

[0023] A first bevel gear 5 is coaxially fixedly connected to the screw 2, an opening 102 is opened on the side wall of the guide groove 101, a positioning bar 7 is fixedly connected between the inner walls of the opening 102, a rotating shaft is rotatably inserted on the positioning bar 7, one end of the rotating shaft is fixedly connected to the second bevel gear 6, the second bevel gear 6 is in meshing contact with the first bevel gear 5, and the other end of the rotating shaft is fixedly connected to a handwheel 8.
