[0026] like Figure 2As shown, the screen compound motion adjustment mechanism A includes a driving mechanism, which is arranged below the base 1 to drive the rotation of the rotating shaft 4, so as to drive the screen 18 through the screen connection device 3.

In other words, the primary transmission worm 14 connected to the drive motor 15 constitutes the axis aa, the double gear 12 independently constitutes the axis bb, the secondary transmission gear 13 and the output shaft 4.2 of the rotating shaft 4 constitute the axis cc, the axis aa and the axis bb are interlaced, the axis bb and the axis cc are parallel to each other, the interface 4.1 of the rotating shaft 4, the screen connecting device 3 and the rotating shaft connecting pin 6 constitute the axis dd, and the fastener 8, the sliding device 5, the base 1, the screen connecting device 3 and the slider connecting pin 7 constitute the axis ee.

[0027] In this embodiment, the screen compound motion adjustment mechanism A further includes a connecting pin bushing 9, which is arranged around the slider connecting pin 7 to eliminate the axial clearance along the ee axis.

[0028] In this embodiment, the screen compound motion adjustment mechanism A further comprises a damping device 10, which is arranged around the rotating shaft connecting pin 6 to provide damping. By means of the crank feature of the rotating shaft 4 and the design of the damping device 10, the screen compound motion adjustment mechanism A makes the clearance in each degree of freedom direction smaller, and the screen 18 (see Figure 1 ) has better control over the amount of sway.

[0029] In this embodiment, the screen compound motion adjustment mechanism A further comprises two gaskets 11, which are arranged between the rotating shaft connecting pin 6 and the screen connecting device 3, and between the screen connecting device 3 and the rotating shaft 4, so as to eliminate the axial clearance along the dd axis.

[0030] In this embodiment, the screen composite motion adjustment mechanism A also includes three bushings 16, which are arranged between the rotating shaft 4 and the base 1, between the secondary transmission gear 13 and the base 1, and between the secondary transmission gear 13 and the box cover 2, so as to completely eliminate the axial clearance along the cc axis.

[0032] The implementation path of the rotation and storage compound adjustment function of the screen compound motion adjustment mechanism A includes: the driving motor 15 drives the primary transmission worm 14 to rotate, the primary transmission worm 14 transmits the motor driving torque to the double gear 12, the secondary transmission gear 13 and the rotating shaft 4, the rotating shaft 4 rotates around the cc axis and continues to transmit the torque to the screen connecting device 3 through the dd axis, and the slider device 5 always performs linear motion under the action of the slide groove 1.1 of the base 1, so that the screen connecting device 3 can perform rotational motion and can also perform linear motion to extend to achieve storage.

[0033] Insert the rotating shaft connecting pin 6 into the screen connecting device 3 and the rotating shaft 4 and then riveting, insert the slider connecting pin 7 into the screen connecting device 3 to obtain the screen connecting sub-assembly, and install the bushing 16 into the base 1 to obtain the base sub-assembly. Figure 3 The installation of the screen base subassembly is described, which is achieved by installing the screen connection subassembly on the base subassembly. The screen connection subassembly and the base subassembly are axially connected in series along the cc axis, and the output shaft 4.2 of the rotating shaft 4 is sleeved in the inner hole 16.2 of the upper and lower bushings. The assembly section 7.2 of the slider connection pin 7 first axially passes through the inner hole 5.1 of the slider device 5 along the ee axis, and then the inner hole 8.1 of the fastener 8 passes through the assembly section 7.2 of the slider connection pin 7, and the end face 8.2 of the fastener 8 fits with the base end face 5.4 of the slider device 5, and the side face 5.2 of the slider device 5 and the step face 5.3 of the slider device 5 are respectively in contact with the slide groove 1.1 of the base 1 and the lower end face of the slide groove of the base 1, so that the fastener 8 axially limits the movement of the slider device 5, so that the slider device 5 can only translate in the slide groove 1.1 of the base 1.

[0034] The cover sub-assembly can be obtained by installing the bushing 16 into the cover 2, and the gearbox sub-assembly can be obtained by installing the drive motor 15 and the transmission gear assembly into the cover sub-assembly. Figure 4 As shown, the screen base subassembly is assembled to the gear box subassembly, wherein the base 1 and the box cover 2 are connected by a plurality of bolts to install the primary transmission worm 14, the double gear 12, the secondary transmission gear 13, and the drive motor 15 in the corresponding areas of the base 1 and the box cover 2, and finally assembled to form the screen compound motion adjustment mechanism A.

[0035] like Figure 5 As shown, the different positions of the screen composite motion adjustment mechanism A include the initial mode in the middle, the co-pilot mode in the left figure, and the main driver mode in the right figure. In the co-pilot mode, the screen connection device 3 can be rotated around the cc axis through the rotation shaft 4 and pushed out along the +x / +y direction. The push-out amount is determined by the position / stroke of the slider device 5 in the base slide groove 1.1. The same applies to the main driver mode (the screen connection device 3 is pushed out along the +x / -y direction).
