The rear ends of the front and rear turnover type handrails are hinged to a framework of the auxiliary instrument panel assembly and can turn over backwards. The left and right split type armrests are designed into a left half mode and a right half mode, the left and right half armrests are hinged to the framework of the auxiliary instrument panel assembly, and the left and right half armrests can be folded and unfolded when needed. The front and back overturning type handrails and the left and right split handrails are provided with storage spaces below, so that the storage requirement is met.

However, both the front and rear convertible armrests and the left and right split armrests have only two states, namely a natural state before adjustment and a deployed state after adjustment, and the deployed state after adjustment cannot effectively serve as the armrest function and cannot be adapted to the seat of the driver or the co-driver to achieve the optimal man-machine use state.

The handrail system has the advantages that the structural design is ingenious, the guide rail pipe 25 is kept still when the handrail system is adjusted in the front and back direction, and the second air cylinder pipe 26 moves along the guide rail pipe 25; when the air cylinder pipe 37 is adjusted left and right, the third air cylinder pipe 37 is kept still, the mounting rod passes through the third air cylinder pipe 37 to move left and right, and the upper and lower, the front and back, the left and right and the rotation are integrated into a whole through different connection relations and relative movement relations.

The detailed working principle of the application is as follows:

as shown in fig. 1, 2 and 3, when adjusting up and down, the high-pressure air of the air pump 3 is divided into two first air pipe 7 through the first air passage pipe and the dividing pipe 9, and pushes the stay bar pipe 2 to move upward, and the stay bar pipe 2 drives the handrail body 1 to move upward. When the handrail needs to move downwards, the exhaust port is opened to release pressure, and the handrail body 1 moves downwards to complete the up-and-down movement.

As shown in fig. 4 and 5, during forward and backward adjustment, the third electromagnetic switch 24 is first turned on, and the control block 240 blocks the passage of the forward extending section 250, so that the passage of the forward extending section 251 is unblocked; the high-pressure air of the air pump 3 enters the guide rail pipe 25 through the stay bar pipe 2 positioned at the front side, and enters the air chamber 28 through the airflow hole, so that the second air cylinder pipe 26 is pushed to move forward along the guide rail pipe 25, and the second air cylinder pipe 26 drives the handrail body 1 to move forward. The distance of travel is controlled by controlling the amount of gas that enters. If the handrail moves backwards, the second electromagnetic switch 23 exhausts air and releases pressure, the handrail body 1 is pulled back by the first return spring 27, and the backward movement distance is controlled by controlling the exhaust amount, namely the forward and backward movement is completed.

As shown in fig. 6, 7, 8 and 9, during left-right adjustment, the high-pressure air of the air pump 3 reaches the third rubber valve 31 through the third air passage tube 6, and when reaching a certain air pressure threshold, the third rubber valve 31 is flushed open, the air enters the stay tube 2 at the rear side, then enters the rear extension section 252, then enters the air passage in the mounting rod 36 of the rear movable assembly 2002 through the inner cavity of the rotary sleeve rod 33 and the fourth air passage tube 35, and then enters the third air tube 37 through the air hole of the mounting rod 36. The third air tube 37 is fixed, the air pushes the installation rod 36 to slide leftwards, if the installation rod needs to be reset, the fourth electromagnetic switch 34 is switched on to exhaust and release the air, the handrail body 1 is pulled back by the second reset spring 38, the backward moving distance is controlled by controlling the air displacement, and the left and right moving of the handrail body 1 is completed.

As shown in fig. 10, 11 and 12, when the rotation adjustment is performed, the third electromagnetic switch 24 is turned off, so that the stopper 240 is controlled to flow to the front extension section 250, and the passage flowing to the middle section 251 is blocked; the high-pressure air of the air pump 3 enters the front extension section 250 and the rotary air cylinder 42 through the stay bar pipe 2 positioned at the front side, the rotary air cylinder 42 is pushed to rotate along the front extension section 250, and the rotary air cylinder 42 drives the handrail body 1 to rotate. The angle of rotation is controlled by controlling the amount of gas admitted. If the handrail moves backwards, the air is exhausted and the pressure is relieved, the handrail body 1 is pulled back by the torsion spring 41, and the return angle is controlled by controlling the air exhaust amount, so that the rotary movement of the handrail is completed.
