Description
Technical Field
The utility model relates to the technical field of vehicles, in particular to a vehicle.
Background
Shared bicycles have become a relatively popular means of travel. A collision switch is arranged on a rear armrest of the shared bicycle seat, and when the collision switch is closed due to collision, the bicycle is judged to be ridden by multiple persons. At this time, the sharing bicycle cuts off the power output. However, the probability of misjudgment is high in the method.
In another mode, a load sensor is additionally arranged at a damping spring rod of a rear wheel of the vehicle. The load sensor sends the information of the load value of the vehicle to the main control device. The master control device judges whether the vehicle is overloaded. After confirming the overload, the main control device sends a command to the electric control device to cut off the power output. Since the weight sensed by the load cell on the rear wheel shock spring rod is substantially derived from the pressure on the seat and the rear arm rest, the weight sensed by the load cell is inaccurate in the case of a person standing at the pedal.
Therefore, a new technical solution is needed to solve the above technical problems.

The main control device carries out coupling processing on the data obtained by the load sensing device 4, calculates a real load value, judges whether the load value exceeds a preset load value or not, and further accurately judges whether a multi-person riding event exists or not.
As shown in fig. 1 and 2, the front camber load sensor is located between the third bar 303 and the second bar 302, and the rear shock-absorbing load sensor is located on the first bar 101. When the frame is deformed by a force, the front camber beam load cell detects the deformation amount at the corners of the third bar 303 and the second bar 302, and the rear shock-absorbing load cell detects the deformation amount of the first bar 101. Deformation quantities of the front bending beam load sensor and the rear shock absorption load sensor are transmitted to the digital conversion control box in the form of electric signals.

Both the front load value and the rear load value are transmitted to the main control device. The main control device couples the front load value transmitted from the corner of the third rod 303 and the second rod 302 of the vehicle to obtain the real load value. The main control device couples the rear load value transmitted from the first rod 101 of the vehicle to obtain the seat cushion load value of the first rod 101. And the main control device couples the real load value and the cushion load value to obtain a final load value of the vehicle. And the main control device judges whether the vehicle has a multi-person riding event according to the final load value of the vehicle obtained by final coupling.
The load sensors are arranged on the front bent beam and the rear shock absorber of the vehicle, so that the final load value of the vehicle can be accurately measured, and an accurate basis is provided for the main control device to judge whether a multi-person riding event occurs.
In one example, the load sensing device 4 is a resistive strain gauge.
