DETAILED DESCRIPTION

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme of the embodiments of the utility model will be clearly and completely explained in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0018] As shown in Figure 1 And Figure 2 The utility model discloses a four -way adjustable mechanism of EPS pipe column, including pipe column structure 1, mounting bracket 2, long screw rod 3, adjusting cam 4 and adjusting handle 5, pipe column structure 1 with mounting bracket 2 is connected, and is used for assembling on the car, the front end of long screw rod 3 is slidably connected in mounting bracket 2 along the front and back direction, adjusting cam 4 and adjusting handle 5 are set in the rear side of mounting bracket 2, the front side of adjusting handle 5 is provided with locking cam 51, locking cam 51 is coaxial with adjusting cam 4 distribution, and relatively rotates, the rear end of long screw rod 3 passes adjusting cam 4, locking cam 51 and adjusting handle 5 in proper order, pipe column structure 1 is used for telescoping along the up and down direction.

[0019] In the embodiment, by pulling adjusting handle 5, locking cam 51 on adjusting handle 5 is driven to rotate, so that adjusting cam 4 and locking cam 51 appear gap in axial direction, then locking cam 51 loses the limiting effect of adjusting cam 4 in front and back direction, so that long screw rod 3, pipe column moves along the front and back direction relative to mounting bracket 2, so as to realize the adjusting function of pipe column structure 1 in front and back direction. Secondly, pipe column structure 1 telescopes along the up and down direction, can realize the adjusting function of pipe column structure 1 in up and down direction. In addition, by pulling adjusting handle 5, locking cam 51 on adjusting handle 5 is driven to rotate, so that adjusting cam 4 and locking cam 51 are pasted in axial direction, locking cam 51 can be used to limit adjusting cam 4, which can prevent long screw rod 3, pipe column from moving along the front and back direction relative to mounting bracket.

[0020] Therefore, by rotating adjusting handle 5, gap appears between adjusting cam 4 and locking cam 51, long screw rod 3 drives pipe column to move along the front and back direction relative to mounting bracket, and pipe column itself telescopes along the up and down direction, which can make pipe column structure 1 adjust in up, down, front and back directions, meet the position and angle of different steering wheel adapted to different drivers, that is, can meet the reliability of product, and can improve the comfort of driver.

[0021] Optionally, as shown in Figure 1As shown, the EPS column four-way adjustable mechanism further comprises a self-locking nut 61, which is sleeved on the rear end of the long screw rod 3 and located at the rear side of the adjusting handle 5.

[0022] In this embodiment, by arranging the self-locking nut 61, the adjusting cam 4, the locking cam 51 and the adjusting handle 5 on the long screw rod 3 can be fixed on the long screw rod 3 by the self-locking nut 61 and the long screw rod 3, so as to prevent disengagement.

[0023] Optionally, as shown in the figure, Figure 1 As shown, the EPS column four-way adjustable mechanism further comprises a tapered washer 62 and a flat bearing 63, which are sleeved on the rear end of the long screw rod 3 in sequence from front to back, and located between the adjusting handle 5 and the self-locking nut 61.

[0024] In this embodiment, by arranging the tapered washer 62 between the adjusting handle 5 and the self-locking nut 61, the fastening force of the self-locking nut 61 can be increased. By arranging the flat bearing 63, the wear between the self-locking nut 61 and the tapered washer 62 can be reduced.

[0025] Optionally, as shown in the figure, Figure 2 As shown, the column structure 1 comprises an upper column barrel 11 and a lower column 12, which is coaxially distributed with the upper column barrel 11, is inserted into the upper column barrel 11 and is in clearance fit with the upper column barrel 11, and the long screw rod 3 is used to connect with the upper column barrel 11.

[0026] In this embodiment, by sliding the upper column barrel 11 relative to the lower column 12 along the axial direction, the long screw rod 3 and the upper column barrel 11 can be driven to move relative to the mounting frame along the up-down direction, so that the column structure 1 can be adjusted in the up-down direction, and the effect of ensuring the column structure 1 to be telescopic in the up-down direction is achieved.

[0027] Optionally, as shown in the figure, Figure 2 As shown, the column structure 1 further comprises a sliding groove guide rail 13, which is installed on the upper column barrel 11 and extends along the up-down direction, and the long screw rod 3 is slidingly connected to the sliding groove guide rail 13.

[0028] In this embodiment, by installing the sliding groove guide rail 13 on the upper column barrel 11 and passing the long screw rod 3 through the sliding groove guide rail 13, the long screw rod 3 can be limited by the sliding groove guide rail 13, so as to ensure the long screw rod 3 and the upper column barrel 11 to move along the up-down direction.

[0029] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features therein can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
