In order to solve the problem that the vehicle-mounted display screen mechanism in the prior art cannot realize the telescopic adjustment and the angular adjustment of the vehicle-mounted display screen at the same time and requires a plurality of motor drives, the first aspect of the present utility model provides a side turning mechanism comprising a support plate 1, a support seat 2 provided on the support plate 1, and a link assembly 3 provided on the support plate 1 and drivingly connected to the support seat 2, the support seat 2 being capable of being driven by the link assembly 3 to slide between a centered position and a left offset position about a first central axis located on the right side with respect to the support plate 1, and the support seat 2 being capable of being driven by the link assembly 3 to slide between the centered position and the right offset position about a second central axis located on the left side with respect to the support plate 1, in the centered position, the support seat 2 being axially symmetrically arranged about a symmetry axis of the support plate 1 in the front-rear direction.

As shown in fig. 1, the support plate 1 may be a symmetrical structure, and is used for supporting the whole side rotating mechanism and connecting with the display screen 8. With the support plate 1 as a reference point, the relative orientation is defined: the center position can be set as the position of the supporting seat when the display screen 8 does not rotate sideways, the left offset position can be set as the position of the supporting seat when the display screen 8 faces the main driver seat, and the right offset position can be set as the position of the supporting seat when the display screen 8 faces the auxiliary driver seat; the front of the support plate 1 may be set toward the position where the driver's seat is located, the rear of the support plate 1 may be set toward the position where the vehicle instrument desk is located, and the front and rear sides of the support seat may be kept coincident with the front and rear sides of the support plate 1; with the center axis of the support plate 1 in the front-rear direction as a reference, the right side of the support plate 1 may be set to the side where the main driver's seat is located, and the left side of the support plate 1 may be set to the side where the auxiliary driver's seat is located. In the centered position, the support seat 2 may be arranged substantially axisymmetrically with respect to the symmetry axis of the support plate 1 in the front-rear direction.

Specifically, in this aspect, the movement of the support base 2 may be achieved by the link assembly 3, and when the support base 2 moves from the centered position to the left offset position (i.e., toward the main driver's seat), the support base 2 is rotated about the first center axis located on the right side by the link assembly 3 and may move forward a certain distance while being rotated sideways. The same applies to the support seat 2 being rotated from the centered position to the right offset position (i.e., toward the passenger seat) by the linkage assembly 3.

In addition, in the scheme, the movement track of the supporting seat 2 on the supporting plate 1 can be adjusted according to actual demands, the adjustment can be realized by changing the structure of the connecting rod assembly 3 (for example, the length of each connecting rod in the connecting rod assembly 3 and the like) and the rotation angle of the connecting rod assembly 3, and finally, the adjustment of the movement track of the display screen 8 is realized, so that the problems that the shielding area of the display screen 8 by a steering wheel is overlarge when the display screen rotates towards the main driving seat side and the distance between the display screen 8 and a combined switch and a steering wheel gap is too small when the display screen rotates towards the auxiliary driving side are effectively avoided.

As shown in fig. 1-3, the second end of the second link 32 may be located on an axis of symmetry of the support plate 1, and the third hinge axis is fixed in position relative to the support plate 1; in the centered position, the first hinge shaft, the second hinge shaft and the third hinge shaft are all positioned on the axis symmetry line of the support plate 1; when the second hinge shaft rotates around the third hinge shaft in the right-front direction from the center position to the left-offset position, the first link 32 (including the first hinge shaft) is driven to translate in the right-front direction, and the same is true when the second hinge shaft moves from the center position to the right-offset position.

Further, in the centered position, the second link 32 extends rearward along the axis of symmetry, and in the left offset position, the second link 32 is to the right of the axis of symmetry, and in the right offset position, the second link 32 is to the left of the axis of symmetry. As shown in fig. 1-3, in the centered position, the first end of the second link 32 may be located rearward of the second end of the second link 32, where each end point of the link assembly 3 is, in the front-to-rear direction, the first end of the first link 31, the second end of the second link 32, and the second end of the first link 31 (i.e., the first end of the second link 32) in that order from front to rear; in the left offset position, the first end of the second link 32 may be located at a right front position of the second end of the second link 32, and the second link 32 is located entirely on the right side of the symmetry axis of the support plate 1, where the end points of the link assembly 3 are, in the front-rear direction, the first end of the first link 31, the second end of the first link 31 (i.e., the first end of the second link 32), and the second end of the second link 32 in this order from front to rear, and in the right offset position, the same applies.
