In comparison, in the prior art, as shown in fig. 2:

h3: the width of the cab 10;

h4: the width occupied by the pedal body 50;

h5: the effective width of the floor assembly 40.

Because the width H3 of the cab 10 is limited and the floor assembly 40 is high above the ground, the existing forklift is also provided with the pedal body 50 for the convenience of getting on and off the vehicle by the driver; in order to allow the pedal body 50 to really play a role of facilitating getting on and off of the vehicle, the size H4 must be large enough, so that the H5 size of most of vehicle types is small due to the fact that the space of H5 is necessarily compressed on the premise that H3 is limited, and H5 is a foot space, so that the operation space of a driver is small, and the comfort is poor.

However, in the pedal system 5 provided in the embodiment of the present invention, the second telescopic adjusting device drives the pedal body 50 to move in the horizontal direction, so that the pedal body 50 extends outward when the driver gets on or off the vehicle, so as to enable the driver to get on or off the vehicle more conveniently, and when the driver is in a normal driving state, the second telescopic adjusting device drives the pedal body 50 to retract, and the hidden pedal body 50 can be used to solve the problem of compressing the step space of the driver in the prior art, so as to improve the comfort of the driver during driving to a certain extent.

For the third step, when the driver is out of the seat (SA1 ═ 0), the controller controls the first electric push rod 42 of the floor manipulating system 4 to shorten (the relay KA1 ═ 1, the relay KA2 ═ 0) to lower the floor assembly 40, and controls the second electric push rod 52 of the pedal system 5 to extend (the relay KA3 ═ 1, the relay KA4 ═ 0) to extend the pedal body 50; when the first electric push rod 42 retracts to the first preset position, the first electric push rod 42 is controlled to stop, and when the second electric push rod 52 extends to the second preset position, the second electric push rod 52 is controlled to stop.

The preset position refers to the limit position which can be reached by the corresponding electric push rod.

For the fourth step, when the driver is in the seat (SA1 ═ 1), the controller controls the first electric push rod 42 of the floor manipulating system 4 to extend (the relay KA1 is 0, the relay KA2 is 1) to raise the floor assembly 40, and controls the second electric push rod 52 of the pedal system 5 to shorten (the relay KA3 is 0, the relay KA4 is 1) to retract the pedal body 50; when the first electric push rod 42 is retracted to the first memory position, the first electric push rod 42 is controlled to stop, and when the second electric push rod 52 is extended to the second memory position, the second electric push rod 52 is controlled to stop.

The memory position refers to a position which is reached before the corresponding electric push rod and can be used for improving the driving comfort of the driver.

Regarding manual switch control:

the set of switch buttons includes a first button SB1 for lowering the floor assembly 40 and a second button SB2 for raising the floor assembly 40. The push button SB1 and the push button SB2 control the shortening and extending operations of the first electric push rod 42, respectively. When the first button (SB1 ═ 1) for lowering the floor assembly 40 is pressed, the controller controls the first electric push rod 42 to shorten (the relay KA1 ═ 1, the relay KA2 ═ 0), and pulls the floor assembly 40 downward; when the second button SB2 (1) for raising the floor assembly 40 is pressed, the controller controls the first electric push rod 42 to extend (the relay KA1 (0), and the relay KA2 (1)), so as to push the floor assembly 40 to raise upward.

When each control action is stopped, the controller reads and records the position information of the electric push rod and covers the last recorded position information.
