Furthermore, the control arm 4 has two notches 43 arranged at a distance from each other, and half shafts 431 protrude from the inner walls of the notches 43, and the engagement between the half shafts and the first and

second driving mechanisms

As shown in fig. 4G to 4H, the base 5 has two positioning pins 51 protruding toward the ball hinge 3, which are inserted into the positioning holes 311 (see fig. 4B) of the bearing housing 31 of the ball hinge 3, respectively, for positioning, thereby mounting the bearing housing 31 of the ball hinge 3 on the base 5. In addition, the base 5 has a screw hole 52, whose cooperation with the first drive mechanism 7a and the second drive mechanism 7b will be described below. Furthermore, the base 5 also has a mounting hole 53, the fitting of which with the double knuckle bearing 8 will be described below.

The first drive mechanism 7a and the second drive mechanism 7b have the same configuration, and the following description will be specifically made by taking only the second drive mechanism 7b as an example.

As shown in fig. 3B, the second driving mechanism 7B includes a motor 71, a lead screw 76 and a first universal joint, wherein the motor 71 is connected with the lead screw 76 to drive the lead screw 76 to rotate through the motor 71, the lead screw 76 passes through the first universal joint to drive the first universal joint to move along the lead screw 76 through the rotation of the lead screw 76, and the first universal joint is connected with the control arm 4, so that the control arm 4 drives the ball head 32 of the ball joint 3 to deflect on the bearing seat 31 in response to the movement of the first universal joint along the lead screw 76. In this way, when the lead screw 76 rotates, the lead screw nut 77 can be driven to slide along the axial direction of the lead screw 76, and then the control arm 4 is pushed to start deflecting, and then the angle of the screen 1 is controlled.

The first gimbal comprises a lead screw nut 77 and a gimbal cage 78, wherein the lead screw 76 is connected through the lead screw nut 77, and the lead screw nut 77 is fitted in a groove in the middle of the gimbal cage 78, so that when the lead screw nut 77 moves along the lead screw 76, the lead screw nut 77 is allowed to rotate in the gimbal cage 78. Specifically, the lead screw nut 77 has a lead screw hole 771, and the lead screw 76 is inserted into and fitted into the lead screw hole 771. The feed screw nut 77 has a feed screw shaft 772, and the gimbal cage 78 has a first shaft hole 781, and the feed screw shaft 772 is inserted into the first shaft hole 781 to be rotatably fitted to enable the feed screw nut 77 to rotate in the gimbal cage 78. Additionally, the gimbal cage 78 also has a second axle hole 782 that cooperates with the half-axle 431 within the notch 43 of the control arm 4 to enable the gimbal cage 78 to rotate within the notch 43. In this manner, the first shaft hole 781 of the gimbal cage 78 is staggered from the axis of the second shaft hole 782 to form a gimbal to meet any mating angle with the lead screw 76.

As shown in fig. 3B, the second driving mechanism 7B further includes a first bracket 72 and a second bracket 73, wherein the motor 71 is connected to the base 5 through the first bracket 72 and the second bracket 73, the first bracket 72 and the second bracket 73 are rotatably connected, the second bracket 73 is rotatably connected with respect to the base 5, and a rotation axis of the first bracket 72 and a rotation axis of the second bracket 73 are arranged alternately. Specifically, the second driving mechanism 7b further comprises a setscrew 74 and a shaft pin 75, the first bracket 72 and the second bracket 73 are rotatably hinged by the shaft pin 75, the second bracket 73 is rotatably fixed to the screw hole 52 of the base 5 by the setscrew 74, and the axes of the setscrew 74 and the shaft pin 75 are perpendicular to each other, thereby forming a universal joint to meet the rotation requirement.

As shown in fig. 2B-3A, the mounting mechanism further includes a double knuckle bearing 8 connecting the control arm 4 and the base 5 to restrict the control arm 4 from rotating relative to the base 5 about the direction of extension of the main shaft 21. As shown in fig. 4I, the double knuckle bearing 8 includes a rod 81 and through holes 82 at both ends of the rod 81, wherein the through holes 82 can freely rotate on the rod 81. As shown in fig. 4J, the through holes 82 of the double knuckle bearing 8 are fixedly connected with the mounting hole 42 (see fig. 4F) of the control arm 4 and the mounting hole 53 (see fig. 4G) of the base 5, respectively, for example, by means of screw fastening, so that the rotational freedom of the bracket 2 is limited by the joint constraint of the double knuckle bearing 8 and the ball joint 3. Thus, according to the mounting mechanism of the present invention, the vertical pitch adjustment (rotation around the lateral direction of the vehicle body) of the screen 1 is restricted by the first drive mechanism 7a, the yaw adjustment (rotation around the longitudinal direction of the vehicle body) of the screen 1 is realized by the second drive mechanism 7b, and the rotation/shake of the screen 1 around the front-rear direction of the vehicle body is restricted by the double knuckle bearing 8, thereby realizing three-dimensional control adjustment of the screen 1 by the first drive mechanism 7a, the second drive mechanism 7b and the double knuckle bearing 8.

As shown in FIG. 3A, the mounting mechanism further includes a resilient member 9 coupled between the control arm 4 and the base 5. In this embodiment, the elastic member 9 is a spring support rod, one end of which is fixed to the control arm 4, and the other end of which is fixed to the base 5, so as to provide a continuous pre-tightening force for the control arm 4 and the base 5, thereby preventing the screen 1 from loosening and shaking caused by the gap between the first driving mechanism 7a and the second driving mechanism 7 b. It should be understood that the arrangement position of the spring stay 9 is preferably between the axial angles of the lead screws 76 of the first and

second driving mechanisms

7a and 7b, so that the deflection stability of the control arm 4 and the screen 1 is improved by the spring stay 9.

Fig. 5a 1-5 A3, 5B 1-5B 3, 5C 1-5C 3 respectively show the movement process of the up-down pitch adjustment of the screen according to the present embodiment through different viewing angles.

As shown in fig. 5a1, 5B1, and 5C1, the motor 71 of the first driving mechanism 7a pushes the gimbal cage 78 to the end of the lead screw 76 through the lead screw 76, and causes the control arm 4 and the screen 1 to deflect upward.

As shown in fig. 5a2, 5B2 and 5C2, the motor 71 of the first driving mechanism 7a slides the gimbal cage 78 to the middle of the lead screw 76 through the lead screw 76, and drives the control arm 4 and the screen 1 to turn to the vertical position.

As shown in fig. 5a3, 5B3 and 5C3, the motor 71 of the first driving mechanism 7a pulls the gimbal cage 78 to the root of the lead screw 76 through the lead screw 76, and drives the control arm 4 and the screen 1 to deflect downward.

Fig. 6a 1-6 A3, 6B 1-6B 3, 6C 1-6C 3 respectively show the movement process of the screen left and right yaw adjustment of the present embodiment through different viewing angles.

As shown in fig. 6a1, 6B1, and 6C1, the motor 71 of the second driving mechanism 7B pulls the gimbal cage 78 to the root of the lead screw 76 through the lead screw 76, and drives the control arm 4 and the screen 1 to deflect to the driving side.

As shown in fig. 6a2, fig. 6B2 and fig. 6C2, the motor 71 of the second driving mechanism 7B slides the gimbal cage 78 to the middle of the lead screw 76 through the lead screw 76, and drives the control arm 4 and the screen 1 to turn to the vertical position.

As shown in fig. 6a3, 6B3, and 6C3, the motor 71 of the second drive mechanism 7B pushes the gimbal cage 78 to the end of the lead screw 76 through the lead screw 76, and causes the control arm 4 and the screen 1 to deflect to the passenger side.
