[0050] The features and performances of the utility model will be further described in detail in combination with the embodiments.

[0051] Embodiment 1 of the instrument desk assembly adjusting mechanism in the utility model:

[0052] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the instrument panel assembly adjusting mechanism comprises a base for fixed connection with the vehicle body and a connecting bracket for connecting the instrument panel and the steering column 14, the base comprises a base plate 1 and two left and right fixing seats 2 fixed on the base plate 1, and the two fixing seats 2 each comprise a guide plate 2-1, and the two guide plates 2-1 are arranged in parallel left and right. The base plate 1 is provided with a connecting structure for fixed connection with the vehicle body, which is a second bent edge 1-2, and the base plate 1 is fixedly connected with the cross beam 23 (as shown) in front of the vehicle cab through the second bent edge 1-2. Figure 3

[0053] The connecting bracket comprises a column connecting frame 3 for connecting with the steering column 14 and an instrument panel connecting frame 4 for connecting with the instrument panel, and the column connecting frame 3 is located at the rear side of the instrument panel connecting frame 4 and is fixed with the instrument panel connecting frame 4. The column connecting frame 3 comprises two left and right connecting arms 3-1, a connecting cylinder 3-2 for connecting with the steering column 14, and a connecting plate 3-3 for connecting with the instrument panel connecting frame 4. The two connecting arms 3-1 are located between the two guide plates 2-1, and a linkage bracket 5 is further arranged between the two guide plates 2-1, and the linkage bracket 5 is hinged with the column connecting frame 3. In combination with Figure 8 and Figure 9 As shown, the linkage bracket 5 comprises a linkage plate 5-1 and linkage side walls 5-2 connected to the left and right sides of the linkage plate 5-1, and the two linkage side walls 5-2 are respectively provided with a hinge arm 5-3, and the two hinge arms 5-3 are respectively hinged with the two connecting arms 3-1 through hinge components and the hinge components are guided up and down with the guide plates 2-1.

[0054] Specifically, the hinge component comprises a hinge shaft penetrating through the guide plates 2-1, the connecting arms 3-1 and the hinge arms 5-3, and a sleeve 25 sleeved on the hinge shaft, and a bolt 24 is adopted as the hinge shaft in the embodiment, wherein the through holes on the guide plates 2-1 and the connecting arms 3-1 are plain holes, and the through hole on the hinge arm 5-3 is a threaded hole, and the bolt 24 is connected with the threaded hole on the hinge arm 5-3, so that the assembly is relatively convenient. Of course, in other embodiments, the through holes on the guide plates 2-1, the connecting arms 3-1 and the hinge arms 5-3 can all be plain holes, and a nut is installed after the bolt 24 penetrates through the three.

[0055] The through hole on the guide plate 2-1 for the bolt 24 to penetrate through is a second long hole 2-2 extending up and down, and the guide sleeve 25 is in contact with the hole wall of the second long hole 2-2 to avoid the direct contact between the bolt 24 and the hole wall of the second long hole 2-2, thereby avoiding the abrasion of the hole wall. Further, in combination with Figure 11 ​As shown, the guide sleeve 25 includes a rectangular section 25-1 with a rectangular outer profile cross section, and the two opposite sides of the rectangular section 25-1 are in contact with the two opposite hole walls of the second long hole 2-2, and the contact area is larger, which is considered that the second long hole 2-2 does not extend vertically up and down, but extends obliquely up and down, and when the linkage bracket 5, the pipe column connecting bracket 3 and the instrument table connecting bracket 4 are adjusted in place, the weight will act on the hole walls of the second long hole 2-2 through the guide sleeve 25, so the face-to-face contact of the guide sleeve 25 and the hole walls of the second long hole 2-2 can increase the support area, which is beneficial to the stable support.

[0056] Further, the guide sleeve 25 further includes a circular section 25-2 with a circular outer profile cross section, and the circular section 25-2 is connected with the rectangular section 25-1. Figure 3 As shown, the outer side of the guide plate 2-1 is provided with a sink groove 2-5 with a groove width greater than the width of the second long hole 2-2 at the hole opening position of the second long hole 2-2, and the circular section 25-2 is located in the sink groove 2-5 and is in stop cooperation with the gasket sleeved on the bolt 24, so that the position of the guide sleeve 25 can be positioned, and the installation of the guide sleeve 25 is facilitated. Of course, in other embodiments, the gasket can not be sleeved on the bolt 24, and at this time the circular section 25-2 is directly in stop cooperation with the head of the bolt 24.

[0057] The linkage bracket 5 and the guide plates 2-1 on both sides are respectively provided with guide structures for up-down cooperation. Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown, the guide structure includes a first groove 5-6 extending up and down and closed at both upper and lower ends, which is arranged on each linkage side wall 5-2, and a second groove 2-3 extending up and down and closed at both upper and lower ends, which is arranged on each guide plate 2-1, the first grooves 5-6 and the second grooves 2-3 on both sides are oppositely arranged and the grooves are provided with balls 26 with a groove width adapted to the groove width, and the sum of the groove depths of the first grooves 5-6 and the second grooves 2-3 is equal to the diameter of the balls 26, so that the up-down guide between the linkage bracket 5 and the guide plate 2-1 can be realized, the friction force when the two relatively move can be reduced, and the limit position of the up-down movement of the linkage bracket 5 can be determined.

[0058] Further, the groove depth and groove width of the first groove 5-6 and the second groove 2-3 are equal respectively, which facilitates the machining of the grooves and the installation of the balls 26. Meanwhile, the balls 26 in the single-sided groove are provided with two or more, three in the embodiment, which is considering that the first groove 5-6 and the second groove 2-3 do not extend vertically up and down, but extend obliquely up and down. When the linkage bracket 5, the pipe column connecting bracket 3 and the instrument table connecting bracket 4 are adjusted in place, the weight thereof will act on the groove wall through the balls 26. Therefore, the supporting effect can be improved by increasing the number of balls 26, but the number should not be too much, otherwise it will affect the stroke of the linkage bracket 5 moving up and down.

[0059] In addition, as shown in Figure 8 and Figure 9 , the outer side of each linkage side wall 5-2 is provided with a first boss 5-7, and the first groove 5-6 is arranged at the position of the first boss 5-7, so as to avoid that the arrangement of the first groove 5-6 reduces the wall thickness of the linkage side wall 5-2. Meanwhile, as shown in Figure 7 , the inner side of each guide plate 2-1 is provided with a second boss 2-4, and the second groove 2-3 is arranged at the position of the second boss 2-4, so as to avoid that the arrangement of the second groove 2-3 reduces the wall thickness of the guide plate 2-1.

[0060] The linkage bracket 5 is connected with the base through a height adjustment driving mechanism for driving the linkage bracket 5, the pipe column connecting bracket 3 and the instrument table connecting bracket 4 to move up and down, as shown in Figures 1-5 , the height adjustment driving mechanism comprises a height adjustment motor 10 hinged to the base plate 1 and a height adjustment lead screw 31 driven to rotate by the height adjustment motor 10. The base plate 1 is fixed with a first mounting seat 27, and the height adjustment motor 10 is hinged to the first mounting seat 27 through a first pin shaft 28. A rotatable first rotating block 8 is installed at the middle position of the linkage bracket 5 in the left-right direction, the height adjustment lead screw 31 penetrates through the first rotating block 8 and is threadedly connected with the first rotating block 8, and the rotating axis of the first rotating block 8 and the hinge axis of the height adjustment motor 10 (i.e. the axis of the first pin shaft 28) both extend along the left-right direction.

[0061] The first rotating block 8 comprises a first connecting portion and first mounting portions located at the left and right ends of the first connecting portion, and the first connecting portion is provided with a first threaded hole threadedly connected with the height adjustment lead screw 31. The linkage bracket 5 is fixed with a pair of first clamping blocks 9, and the first mounting portions of the first rotating block 8 are located between the pair of first clamping blocks 9 and the linkage bracket 5 respectively. The first mounting portions and the first clamping blocks 9 and the first mounting portions and the linkage bracket 5 are all connected through arc surface rotation cooperation, which facilitates the rotational installation of the first rotating block 8 and is simple in structure. Specifically, as shown in Figure 8 , the linkage plate 5-1 is provided with a protrusion 5-4, and the arc surface of the linkage bracket 5 is arranged on the protrusion 5-4.

[0062] The linkage support 5 is connected with the instrument desk connecting frame 4, and an angle adjusting driving mechanism for driving the pipe column connecting frame 3 and the instrument desk connecting frame 4 to swing forward and backward around the bolt 24 (i.e. the hinge position of the pipe column connecting frame 3 and the linkage support 5) is arranged between the linkage support 5 and the instrument desk connecting frame 4. Figure 1 、 Figure 2 and Figure 4 As shown in Figs. Figure 8 and Figure 9 , the middle part of the linkage support 5 in the left-right direction and the side away from the first rotating block 8 is provided with a hinge seat 5-5, the hinge seat 5-5 is provided with a rotatable second rotating block 6, the angle adjusting screw rod 13 penetrates through the second rotating block 6 and is threadedly connected with the second rotating block 6, and the rotating axis of the second rotating block 6 and the hinge axis of the angle adjusting motor 12 (i.e. the axis of the second pin shaft 30) both extend in the left-right direction.

[0063] The structure of the second rotating block 6 is the same as that of the first rotating block 8, and as shown in Figs. Figure 9 and Figure 10 , the second rotating block 6 comprises a second connecting part 6-1 and a second mounting part 6-3 located at the left and right ends of the second connecting part 6-1, and the second connecting part 6-1 is provided with a second threaded hole 6-2 threadedly connected with the angle adjusting screw rod 13. The hinge seat 5-5 is fixed with a pair of second clamping blocks 7, and the second mounting parts 6-3 at the two ends of the second rotating block 6 are respectively located between the pair of second clamping blocks 7 and the hinge seat 5-5, and the second mounting parts 6-3 and the second clamping blocks 7 and the second mounting parts 6-3 and the hinge seat 5-5 are all connected through cam surface rotation, so that the second rotating block 6 is rotatably mounted, and the structure is simple.

[0064] In the utility model, the angle adjusting screw rod 13 is only one, the structure is relatively simple, and the configuration cost can be reduced. Meanwhile, the second rotating block 6 is located at the middle part of the linkage support 5 in the left-right direction, i.e. the connecting position of the angle adjusting screw rod 13 and the linkage support 5 is located at the middle part of the linkage support 5 in the left-right direction; the second mounting seat 29 is fixed at the middle part of the instrument desk connecting frame 4 in the left-right direction, i.e. the connecting position of the angle adjusting motor 12 and the instrument desk connecting frame 4 is located at the middle part of the instrument desk connecting frame 4 in the left-right direction, so that the force is applied in the middle, and the instrument desk connecting frame 4 and the pipe column connecting frame 3 can be more smoothly driven to swing forward and backward.

[0065] Further, the connecting position of the angle adjustment motor 12 and the instrument desk connecting frame 4 is located at the rear of the instrument desk connecting frame 4, so that the distance from the connecting position of the angle adjustment motor 12 and the instrument desk connecting frame 4 to the axis of the bolt 24 is far enough, the power arm of the front and rear swing of the instrument desk connecting frame 4 and the pipe column connecting frame 3 is increased, the angle adjustment is more labor-saving, and therefore the configuration cost of the angle adjustment driving mechanism can be reduced.

The middle part of the first support plate 4-1 is provided with a window penetrating up and down, the front side edge of the window is connected with an installation plate 4-4 extending upward, the second mounting seat 29 is fixed on the installation plate 4-4, the angle adjustment motor 12 spans across the two sides of the window, and the angle adjustment motor 12 is arranged horizontally, so that the connecting position of the angle adjustment motor 12 and the instrument desk connecting frame 4 is relatively rear, the arrangement of the angle adjustment motor 12 is facilitated, the angle adjustment motor 12 does not occupy too much space in the height direction, and the structure is relatively compact.

[0067] In addition, the left and right sides of the base plate 1 are respectively provided with a first bending plate 1-1, each first bending plate 1-1 is connected with a static locking plate 11, the left and right sides of the first support plate 4-1 are provided with a dynamic locking plate 4-3 located between the two static locking plates 11, and the instrument desk assembly adjusting mechanism further includes a pneumatic locking supporting device for pressing the dynamic locking plate 4-3 against the corresponding static locking plate 11 under the action of a spring and for releasing the pressing after aeration.

[0068] As shown in Figure 2 , the pneumatic locking supporting device includes a cylinder 16, a piston rod arranged in the cylinder 16 and sealingly matched with the cylinder 16, a cylinder cover arranged at the end of the cylinder 16, and a mounting shaft 15 penetrating through the cylinder 16, the piston rod, the cylinder cover, the two dynamic locking plates 4-3 and the two static locking plates 11, a gas cavity for introducing gas is formed between one side of the piston rod and the cylinder 16, a spring is top-mounted between the other side of the piston rod and the cylinder cover, a first force transmission sleeve 17 is sleeved on the mounting shaft 15 between the piston rod and one of the dynamic locking plates 4-3, a second force transmission sleeve 20 is sleeved on the mounting shaft 15 between the cylinder cover and the other dynamic locking plate 4-3, and the first force transmission sleeve 17 and the second force transmission sleeve 20 are used as force transmission members.

[0069] The second force transmission sleeve 20 is provided with an external thread at one end close to the corresponding movable lock plate 4-3 and is equipped with an adjusting nut 21 through the external thread, which is used to tighten the corresponding movable lock plate 4-3. The air cylinder 16 in this embodiment is an air cylinder, and the pressure medium introduced is gas. When no gas is introduced into the medium cavity, the first force transmission sleeve 17 and the adjusting nut 21 are pressed against the movable lock plates 4-3 on both sides under the action of the spring, thereby pressing and fixing the movable lock plates 4-3 on the static lock plate 11. After the air is introduced, the first force transmission sleeve 17 and the adjusting nut 21 are released from the pressing, and the instrument table connecting frame 4 can move relative to the base plate 1. The principle is similar to the elastic pressing assembly of the air cylinder disclosed in patent CN110466353B, but the adjusting nut 21 can change position to obtain better tightening effect.

[0070] At the same time, the movable lock plate 4-3 extends downward, the mounting shaft 15 is located below the first support plate 4-1, and the air cylinder 16 is located to the right of the angle adjusting motor 12. The air cylinder 16 spans across both sides of the window, which makes the locking support structure form a kind of bottom support for the instrument table connecting frame 4 and the instrument table, and the support effect is better. At the same time, the stress state of the movable lock plate 4-3 is also better. Moreover, there is no need for a large space between the first support plate 4-1 and the second support plate 4-2 to accommodate the air cylinder 16, which can reduce the size of the instrument table connecting frame 4 compared with the prior art.

[0071] Further, the second force transmission sleeve 20 is also equipped with a locking nut 22 through the external thread, which is used to tighten the adjusting nut 21 to lock the position of the adjusting nut 21 and avoid loosening of the adjusting nut 21. In addition, the portions of the mounting shaft 15 that pass through the static lock plate 11 are both threadedly equipped with a fixed nut 19 to limit the locking support structure. Moreover, the portions of the mounting shaft 15 that pass through the static lock plate 11 are both equipped with a pad 18, which is clamped between the fixed nut 19 and the static lock plate 11 to facilitate pressing of the static lock plate 11.

[0072] As shown in Figure 12 , the through hole 4-5 in the movable lock plate 4-3 for the mounting shaft 15 to pass through is a circular hole, as shown in Figure 1 , Figure 3 , the through hole in the static lock plate 11 for the mounting shaft 15 to pass through is a first long hole 11-1 extending upward and downward, and the mounting shaft 15 and the first long hole 11-1 have a sufficient fitting gap, which is not less than the front and rear swinging stroke of the instrument table connecting frame 4, to ensure that the pipe column connecting frame 3 and the instrument table connecting frame 4 can swing front and rear around the bolt 24. In addition, as shown in Figure 12 , the movable lock plate 4-3 has a certain front and rear width, which further optimizes the stress state of the movable lock plate 4-3 and ensures the support effect of the instrument table connecting frame 4 on the instrument table. At the same time, to avoid excessive weight, a weight-reducing hole 4-6 is provided on the front side and the rear side of the through hole 4-5.

[0073] The working principle of the instrument desk assembly adjusting mechanism in the utility model is as follows:

[0074] When the height of the direction column and the instrument desk needs to be adjusted, first, air is supplied to the air cylinder 16 to release the locking of the mounting frame 4, then the height adjusting motor 10 is started, the height adjusting motor 10 drives the height adjusting lead screw 31 to rotate, under the action of the screw nut mechanism, the height adjusting rotating block 8 moves up and down along the height adjusting lead screw 31, thereby driving the linkage seat 5, the connecting seat 3 and the mounting frame 4 to move up and down, so that the height of the direction column and the instrument desk is adjusted. During the adjustment, the second long hole 2-2 on the guide plate 2-1 and the ball 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 the adjustment is completed, the height adjusting motor 10 stops working, and at the same time, the air supply of the air cylinder 16 is stopped, the pneumatic locking support device presses the movable locking plates 4-1 on both sides, so that the position of the direction column and the instrument desk is fixed.

[0075] When the angle of the direction column and the instrument desk needs to be adjusted, first, air is supplied to the air cylinder 16 to release the locking of the mounting frame 4, then the angle adjusting motor 12 is started, the angle adjusting motor 12 drives the angle adjusting lead screw 13 to rotate, under the action of the screw nut mechanism, the angle adjusting rotating block 6 moves linearly along the angle adjusting lead screw 13, thereby pulling or pushing the mounting frame 4 and the connecting seat 3 to swing around the bolt 24, so that the angle of the direction column and the instrument desk is adjusted. 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 the adjustment is completed, the angle adjusting motor 12 stops working, and at the same time, the air supply of the air cylinder 16 is stopped, the pneumatic locking support device presses the movable locking plates 4-1 on both sides, so that the position of the direction column and the instrument desk is fixed.
