[0067] When the height of the steering column and the instrument panel needs to be adjusted, first, the air supply to the air cylinder 16 is controlled to release the locking of the mounting frame 4, then the height adjustment motor 10 is started, the height adjustment screw 31 is driven to rotate, under the action of the screw nut mechanism, the height adjustment rotating block 8 moves up and down along the height adjustment screw 31, thereby driving the linkage seat 5, the connecting seat 3, and the mounting frame 4 to move up and down, achieving the height adjustment of the steering column and the instrument panel. During the adjustment process, the second long hole 2-2 on the guide plate 2-1 and the ball bearings 26 between the linkage seat 5 and the guide plate 2-1 guide the up and down movement of the linkage seat 5, the connecting seat 3, and the mounting frame 4. After adjustment, the height adjustment motor 10 stops working, and the air supply to the air cylinder 16 is stopped, the pneumatic locking support device compresses the dynamic locking plates 4-1 on both sides, achieving the fixation of the position of the steering column and the instrument panel.

[0068] When the angle of the steering column and the instrument panel needs to be adjusted, first, the air supply to the air cylinder 16 is controlled to release the locking of the mounting frame 4, then the angle adjustment motor 12 is started, the angle adjustment screw 13 is driven to rotate, under the action of the screw nut mechanism, the angle adjustment rotating block 6 moves linearly along the angle adjustment screw 13, thereby pulling or pushing the mounting frame 4 and the connecting seat 3 to swing around the bolt 24, achieving the angle adjustment of the steering column and the instrument panel. The cooperation gap between the mounting shaft 15 and the first long hole 11-1 can meet the swing stroke requirement of the mounting frame 4 and the connecting seat 3. After adjustment, the angle adjustment motor 12 stops working, and the air supply to the air cylinder 16 is stopped, the pneumatic locking support device compresses the dynamic locking plates 4-1 on both sides, achieving the fixation of the position of the steering column and the instrument panel.

[0069] In other embodiments of the instrument panel assembly adjustment structure: according to the transmission mode between the angle adjustment motor and the angle adjustment screw, the angle adjustment motor can also drive the angle adjustment screw to stretch and retract, at this time the end of the angle adjustment screw is hinged to the linkage bracket, and the linkage bracket does not need to be provided with a rotating block, but a hinged ear plate is provided which is hinged to the angle adjustment screw. Of course, in other embodiments, if the angle adjustment screw is a stretching and retracting motion, the angle adjustment screw can also be hinged to the instrument panel connecting frame, and the angle adjustment motor is hinged to the linkage bracket.

[0070] In other embodiments of the instrument panel assembly adjustment structure: the pneumatic locking support device can no longer be provided, and only after the height adjustment motor and the angle adjustment motor stop working, the self-locking action of the angle adjustment screw and the height adjustment screw makes the connecting bracket remain in a predetermined position, and in this case, the dynamic locking plate and the static locking plate no longer need to be provided.

[0071] In other embodiments of the instrument panel assembly adjustment structure: the mounting plate connected to the front side edge of the window on the bracket plate can also extend downward.

[0072] In other embodiments of the instrument panel assembly adjustment structure: the support plate can no longer be provided with a window, and there is no mounting plate provided at the front side edge of the window, and the motor mounting seat can be directly fixed to the bottom surface of the support plate, and the angle adjustment motor is located below the support plate.

[0073] In other embodiments of the instrument panel assembly adjustment structure: the linkage support can also be provided with two, respectively located on the outer side of the guide plate, and the angle adjustment lead screw also has two, respectively connected with a linkage support.

[0074] In other embodiments of the instrument panel assembly adjustment structure: when the angle adjustment lead screw has two and the linkage support also has two, the two linkage supports are respectively located on the outer side of the guide plate, the two angle adjustment lead screws are respectively connected with the instrument panel connecting frame, and the transmission module between the angle adjustment motor and the two angle adjustment lead screws is respectively hinged with the two linkage supports.

[0075] In other embodiments of the instrument panel assembly adjustment structure: the angle adjustment driving mechanism and the height adjustment driving mechanism can also be electric push rods, hydraulic cylinders or air cylinders.

[0076] In other embodiments of the instrument panel assembly adjustment structure: the connection position of the angle adjustment driving mechanism and the instrument panel connecting frame can also be slightly deviated from the middle of the connecting frame in the left-right direction, and will not affect the smooth swinging of the connecting support, especially when the center of gravity of the instrument panel is not in the middle.

[0077] In other embodiments of the instrument panel assembly adjustment structure: the connection position of the angle adjustment driving mechanism and the instrument panel connecting frame can also be located in the middle of the instrument panel connecting frame in the front-rear direction. Since the front-rear size of the instrument panel connecting frame is large, the distance between the connection position and the swinging axis of the pipe column connecting frame is still large, which still has the effect of increasing the power arm.

[0078] In the embodiment of the instrument panel assembly in the utility model, the instrument panel assembly comprises an instrument panel, a direction pipe column, and an adjustment structure for adjusting the height and the front-rear angle of the instrument panel and the direction pipe column, and the adjustment structure is the same as the instrument panel assembly adjustment structure in any of the above embodiments, which will not be repeated here.

[0079] In the embodiment of the vehicle in the utility model, the vehicle comprises a vehicle body and an instrument panel assembly mounted on the vehicle body, the instrument panel assembly comprises an instrument panel, a direction pipe column, and an adjustment structure for adjusting the height and the front-rear angle of the instrument panel and the direction pipe column, and the adjustment structure is the same as the instrument panel assembly adjustment structure in any of the above embodiments, which will not be repeated here.

[0080] The above merely describes preferred embodiments of the present application, and is not used to limit the present application, and the patent protection scope of the present application is subject to the claims, and any equivalent structural changes made according to the content of the specification and drawings of the present application should also be included in the protection scope of the present application.
