Smart helmet system, helmet, and transportation vehicle

A helmet, comprising:

• a body comprising a first lock part of a helmet lock and retention straps, wherein the retention straps comprise a helmet buckle;
• and a second lock part of the helmet lock is mounted on a transportation vehicle;
• a first detection module in communication connection with a control module and configured to detect, during operation, a connection state between the first lock part and the second lock part and send information of the connection state to the control module;
• a second detection module in communication connection with the control module and configured to detect a wearing state of the helmet and send information of the wearing state to the control module;
• and
• a third detection module in communication connection with the control module and configured to detect an engagement state of the helmet buckle and send information of the engagement state to the control module, wherein
• the control module is configured to determine a wearing/return state of the helmet based on the information of the connection state, the information of the wearing state, and the information of the engagement state.

A transportation vehicle, comprising:

• a vehicle frame;
• a front wheel assembly rotatably connected with the vehicle frame;
• a rear wheel assembly rotatably connected with the vehicle frame;
• a smart helmet system;
• and
• a central control system mounted on the vehicle frame and in communication connection with the smart helmet system, wherein
• the smart helmet system comprises:
• a control module,
• a helmet body comprising a first lock part of a helmet lock and retention straps, wherein the retention straps comprise a helmet buckle, and a second lock part of the helmet lock is mounted on a transportation vehicle,
• a first detection module in communication connection with the control module and configured to detect, during operation, a connection state between the first lock part and the second lock part and send information of the connection state to the control module,
• a second detection module in communication connection with the control module and configured to detect a wearing state of the helmet and send information of the wearing state to the control module, and
• a third detection module in communication connection with the control module and configured to detect an engagement state of the helmet buckle and send information of the engagement state to the control module, wherein
• the control module is configured to determine the wearing/return state of the helmet based on the information of the connection state, the information of the wearing state, and the information of the engagement state.
