Since the first electric putter 22 has an extending and contracting function and is capable of receiving an axial pushing force and a pulling force, the swing bracket 23 can swing upward or downward with respect to the mounting bracket 21 about the hinge point a during the extending or contracting operation of the first electric putter 22.
In addition, the fixed end of the linear guide rail 25 is fixedly connected to the swing bracket 23, the sliding end of the linear guide rail 25 is fixedly connected to the steering wheel steering gear 20 through the steering wheel mounting bracket 24, and the fixed end and the sliding end of the linear guide rail 25 can slide relatively, so that the steering wheel mounting bracket 24 and the swing bracket 23 can slide linearly relatively; the fixed end of second electric putter 26 is articulated with swing support 23, and the pin joint is d, and the expansion end of second electric putter 26 is articulated with steering wheel installing support 24, and the pin joint is e. During the extending or shortening operation of the second electric putter 26, the steering wheel mounting bracket 24 is linearly movable relative to the swing bracket 23 in a relative extending or shortening manner.

Meanwhile, the steering wheel steering device 20 is fixedly connected with the steering wheel mounting bracket 24, and is a steering system of an electric steering vehicle type, and specific contents can refer to the prior art, which is not repeated herein.
To optimize the above embodiments, the control system may be arranged to comprise an automatic control system and/or a manual control system. The automatic control system comprises a controller and a seat sensing switch electrically connected with the controller, wherein the seat sensing switch is used for triggering the controller; the manual control system comprises a controller and a switch button group electrically connected with the controller, and the controller is triggered through the switch button group to control the telescopic adjusting device to start and stop. Of course, the controller may be specifically configured as a PLC.
It should be noted that the control function of the controller is well known to those skilled in the art and is not a key point of the present application, and the key point of the present application is to implement the function of controlling the movement of the telescopic adjusting device through the connection relationship of the controller, the seat sensing switch and/or the switch button group.
The control processes of the automatic control system and the manual control system are set forth below, respectively.
Regarding the automatic control:
the first step is as follows: acquiring an induction signal of a seat sensing switch;
the second step is that: judging whether a driver is seated or not according to the induction signal;
the third step: if not, controlling the first electric push rod 22 of the forklift steering wheel operating system 2 to extend to a first preset position, and controlling the second electric push rod 26 of the forklift steering wheel operating system 2 to retract to a second preset position;
the fourth step: if yes, the first electric push rod 22 of the forklift steering wheel control system 2 is controlled to retract to the first memory position, and the second electric push rod 26 of the forklift steering wheel control system 2 is controlled to extend to the second memory position.
In the first and second steps, it is noted that the seat 30 on which the driver sits has a seat sensing switch SA1 therein, and the seat sensing switch SA1 is well known to those skilled in the art, and SA1 is 1 when the driver sits on the seat 30 and SA1 is 0 when the driver leaves the seat 30.
For the third step, when the driver is out of the seat (SA1 ═ 0), the controller controls the first electric push rod 22 of the forklift steering system 2 to extend (relay KA1 ═ 1, relay KA2 ═ 0) to raise the steering wheel 20, and controls the second electric push rod 26 of the forklift steering system 2 to shorten (relay KA3 ═ 1, relay KA4 ═ 0) to retract the steering wheel 20; when the first electric push rod 22 extends to a first preset position, the first electric push rod 22 is controlled to stop, and when the second electric push rod 26 retracts to a second preset position, the second electric push rod 26 is controlled to stop.
The preset position refers to the limit position which can be reached by the corresponding electric push rod.
In the fourth step, when the driver is in the seat (SA1 ═ 1), the controller controls the first electric push rod 22 of the forklift steering system 2 to shorten (the relay KA1 is 0 and the relay KA2 is 1) to lower the steering wheel 20 and controls the second electric push rod 26 of the forklift steering system 2 to extend (the relay KA3 is 0 and the relay KA4 is 1) to extend the steering wheel 20; when the first electric push rod 22 retracts to the first memory position, the first electric push rod 22 is controlled to stop, and when the second electric push rod 26 extends to the second memory position, the second electric push rod 26 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:
specifically, the switch button group includes a first button SB1, a second button SB2, a third button SB3, and a fourth button SB4, wherein the first button SB1 is used to raise the steering wheel 20; the second button SB2 is used to lower the steering wheel diverter 20; the third button SB3 is used to retract the steering wheel 20; the fourth button SB4 is used to extend the steering wheel 20.
When the first button (SB1 is 1) for lifting the steering wheel steering gear 20 is pressed, the controller controls the first electric push rod 22 to extend (the relay KA1 is 1, and the relay KA2 is 0), so as to push the whole set of mechanism to swing upwards (the steering wheel steering gear 20 is lifted); when the second button (SB2 is 1) for lowering the steering wheel 20 is pressed, the controller controls the first electric push rod 22 to shorten (the relay KA1 is 0, and the relay KA2 is 1), and pulls the whole mechanism to swing downwards (the steering wheel 20 is lowered); when the third button for retracting the steering wheel steering device 20 is pressed (SB3 is equal to 1), the controller controls the second electric push rod 26 to shorten (the relay KA3 is equal to 1, and the relay KA4 is equal to 0), and the whole set of mechanisms is pulled to shorten (the steering wheel steering device 20 retracts); when the fourth button SB4 (1) for extending the steering wheel 20 is pressed, the controller controls the second electric push rod 26 to extend (0 for KA3 and 1 for KA 4) to push the entire mechanism to extend (extend the steering wheel 20).
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.
