Anti-cheating safety belt warning device, alarm assembly, safety belt assembly and vehicle

The utility model provides an anti-cheating safety belt warning device, an alarm assembly, a safety belt assembly and a vehicle. The anti-cheating safety belt warning device comprises a vertical tension sensor used for detecting vertical tension applied to a safety belt buckle, a horizontal pressure sensor used for detecting the horizontal pressure applied to the safety belt buckle, and a safety belt state recognition device, wherein the safety belt state recognition device is electrically connected with an alarm element. The anti-cheating safety belt warning device determines whether an alarm needs to be given through comparison between the horizontal component force and vertical component force applied to the safety belt buckle and a normal force value, so that drivers or passengers are warned to wear safety belts correctly. The anti-cheating safety belt warning device can be applied to various vehicles independently and can also be matched with an existing safety belt fastening failure warning system arranged on a vehicle to form the anti-cheating safety belt alarm assembly to be further applied to the safety belt assembly which is installed on various vehicles to be used for warning drivers or passengers to wear the safety belts correctly.
