In order to solve the problem that the vehicle-mounted display screen mechanism in the prior art easily causes excessive backward movement of the screen edge of the vehicle-mounted display screen and interference with an instrument desk when controlling the side rotation of the vehicle-mounted display screen, and the backward movement of the screen edge is not adjustable, the first aspect of the utility model provides a side rotation mechanism, which comprises a support plate 1 and a support seat arranged on the support plate 1, wherein the support seat can rotate between a centered position and a right offset position relative to the support plate 1 around a first central axis positioned at the left front position of the support plate 1, and the support seat can rotate between the centered position and the left offset position relative to the support plate 1 around a second central axis positioned at the right front position of the support plate 1, and the support seat is arranged in a centered position in a spool symmetrical manner relative to the central axis of the support plate 1 along the front-rear direction.

As shown in fig. 1, the support plate 1 may have a symmetrical structure, and is used for supporting the whole side rotating mechanism and connecting with the display screen assembly. With the support plate 1 as a reference point, the relative orientation is defined: the center position can be set to be the position of the supporting seat when the vehicle-mounted display screen does not rotate sideways, the right offset position can be set to be the position of the supporting seat when the vehicle-mounted display screen faces the front passenger seat, and the left offset position can be set to be the position of the supporting seat when the vehicle-mounted display screen faces the main passenger seat; the front part of the supporting plate 1 can be set to be the position of a driving seat, the rear part of the supporting plate 1 can be set to be the position of a vehicle body instrument desk, and the front side and the rear side of the supporting seat can be consistent with the front side and the rear side of the supporting 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. The deflection of the supporting seat in the side rotating mechanism can be realized by means of air cylinders, oil cylinders, motors or manual pushing by manpower and the like.

Specifically, in this scheme, when the side-turning mechanism drives the vehicle-mounted display screen to rotate from the central position to the right offset position (i.e. towards the front passenger seat), because the first central axis around is located at the left front position of the support plate 1, the vehicle-mounted display screen can only generate a smaller backward movement amount (i.e. avoid interference with the instrument desk at the rear) at the left side while guaranteeing the forward movement amount (i.e. the side-turning amplitude) at the right side. The same applies to the case that the side rotating mechanism drives the vehicle-mounted display screen to rotate from the central position to the left offset position (namely, towards the main driver seat).

And in the scheme, the specific positions of the first central axis positioned at the left front position and the second central axis positioned at the right front position can be changed according to actual requirements, so that the adjustment of the position of the vehicle-mounted display screen after the side rotation is realized. After the position change, the first central axis and the second central axis remain symmetrical with respect to the central axis of the support plate 1 in the front-rear direction.

Further, the support base comprises a first support base 3, a second support base 4 and a driving wheel 5, wherein the driving wheel 5 can be in transmission connection with the first support base 3 to drive the first support base 3 to move from the central position to the right offset position, and the driving wheel 5 can be in transmission connection with the second support base 4 to drive the second support base 4 to move from the central position to the left offset position. As shown in fig. 1, the center point of the driving wheel 5 may be disposed on the center axis of the support plate 1 in the front-rear direction. When the side rotating mechanism rotates, the driving wheel 5 can rotate in cooperation with the first supporting seat 3 or the second supporting seat 4, two driven parts are controlled by one driving part, the device structure is optimized, and the production cost is reduced. The first support seat 3 and the second support seat 4 are fixed relative to each other.

As shown in fig. 1 and 4, the first and second supporting seats 3 and 4 may be engaged with the driving wheel 5 through the first and second incomplete driven gears 31 and 41, respectively. Specifically, the support seat is engaged with the second incomplete driven gear 41 during the movement from the centered position to the left offset position, the first incomplete driven gear 31 being disengaged from the driving wheel 5; the support seat, during the movement from the centered position to the right offset position, the driving wheel 5 meshes with the first incomplete driven gear 31, the second incomplete driven gear 41 being disengaged from the driving wheel 5; with the support seat in the centered position, both the first incomplete driven gear 31 and the second incomplete driven gear 41 mesh with the driving wheel 5.
