Tire burst detection device, tire and vehicle

The utility model relates to a tire burst detection device, a tire and a vehicle, and the tire burst detection device comprises a shell which is a sealed cavity capable of generating deformation under the action of preset air pressure; the capillary tube is arranged in the shell, the capillary tube is provided with a first opening and a second opening which are oppositely formed in the two ends, the first opening is located in the shell, and the second opening extends out of the shell and is used for communicating the interior of the shell with the outside; the switch is arranged on the side wall, where the shell deforms, of the shell and is configured to be closed to send out a tire burst signal when the shell deforms due to tire burst. When tire burst does not occur, the air pressure inside and outside the shell is kept balanced through the capillary tube, when tire burst occurs, the air pressure inside the shell is larger than the external air pressure, air flows outwards only through the capillary tube, the air pressure inside the shell can be larger than the external air pressure within a long period of time, and at the moment, the shell deforms under the action of the air pressure to enable the switch to be closed; tire burst signals are transmitted out for follow-up treatment of an automobile, and the safety of the automobile is guaranteed.
