In the prior art, no related technology of an alarm device capable of reminding people inside and outside a vehicle to find hydrogen leakage in time exists.
SUMMERY OF THE UTILITY MODEL
The utility model provides a hydrogen fuel cell commodity circulation car hydrogen reveals alarm device, its purpose in time discovers hydrogen fuel cell's hydrogen and leaks, improves the security of vehicle.
In order to realize the purpose, the utility model discloses the technical scheme who takes does:
the utility model discloses a hydrogen leakage alarm device for a hydrogen fuel cell logistics vehicle, which comprises a vehicle control unit; the hydrogen leakage alarm device is provided with a hydrogen sensor and an external alarm; the hydrogen sensor is arranged in the hydrogen fuel engine room; the alarm outside the vehicle is arranged on the outer surface of the carriage of the hydrogen fuel cell logistics vehicle, and the hydrogen sensor and the alarm outside the vehicle are connected with the whole vehicle controller through signal lines.
The number of the hydrogen sensors is two, and the hydrogen sensors are distributed at different positions of the hydrogen fuel engine compartment.
The alarm outside the vehicle is a sound alarm, or a light flashing alarm, or an alarm combining sound and light flashing.
The hydrogen leakage alarm display dial is arranged on an instrument assembly of the hydrogen fuel cell logistics vehicle and connected with the whole vehicle controller through a signal line.
The alarm outside the vehicle is arranged on the front part of the carriage and the outer surface above the cockpit.
By adopting the technical scheme, when hydrogen is leaked to the hydrogen fuel engine compartment and reaches a certain content, the high-precision hydrogen sensor can send an electronic signal to the controller; hydrogen leaked in the engine compartment is detected according to the sensor to carry out sound-light alarm, so that a driver or other peripheral personnel outside the vehicle is reminded: the vehicle has hydrogen leakage fault, and the explosion-proof operation is noticed in the unlocking process of approaching or operating the vehicle so as to avoid explosion accidents and improve the safety performance of the vehicle.

The number of the hydrogen sensors 3 is two, and the hydrogen sensors are distributed at different positions of the hydrogen fuel engine compartment 4.
The alarm 1 outside the vehicle is a sound alarm, or a light flashing alarm, or an alarm combining sound and light flashing.
The hydrogen leakage alarm display dial is arranged on an instrument assembly of the hydrogen fuel cell logistics vehicle and connected with the vehicle control unit 2 through a signal line.
The alarm 1 outside the vehicle is arranged on the front part of the carriage 5 and the outer surface above the cockpit.
The utility model adds the external alarm 1 on the hydrogen fuel cell logistics vehicle, which is used for providing alarm information for drivers or peripheral personnel in the parking state and monitoring the hydrogen leakage condition of the hydrogen fuel cell cabin through the hydrogen sensor 3; and then the vehicle control unit 2 controls the alarm 1 outside the vehicle to work and provides sound and light alarm to achieve the aim.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
