The components of the turning mechanism of the in-vehicle display screen will be described in detail with reference to the accompanying drawings.

Referring to fig. 6 and 8, the roll-over stand 130 is pivotally connected to the fixed frame 110 by being pivotable about the hinge shaft 126 between a retracted position and a roll-over position. Specifically, the mount 110 has a mount hinge portion 116, and the mount hinge portion 116 has a mount hinge hole 117. The roll-over stand 130 has a roll-over stand hinge 132, and the roll-over stand hinge 132 has a roll-over stand hinge hole 133, and the holder hinge hole 117 is aligned with the roll-over stand hinge hole 133. The holder hinge 116 is configured as two spaced apart hinge ears with the roll-over holder hinge 132 located therebetween. The roll-over stand hinge 132 has two bushings 118, the two bushings 118 being located at the top and bottom of the roll-over stand hinge 132, respectively, and the two bushings 118 being penetrated into both ends of the roll-over stand hinge hole 133 to prevent wear of the roll-over stand hinge hole 133. The lower end of the hinge shaft 126 sequentially penetrates the hinge lug and the roll-over stand hinge 132, and the lower end of the hinge shaft 126 is sleeved with a nut, which is screw-coupled with the hinge shaft 126, so that the roll-over stand 130 is pivotably coupled with the fixing frame 110.

Referring to fig. 7, the display screen rotating assembly 150 includes a rotation driving device, a display screen connector 151 for connecting to the in-vehicle display screen 100, and a rotation driving device mounting portion 153 accommodating the rotation driving device. The rotation driving device is disposed in the rotation driving device mounting portion 153, and the rotation driving device mounting portion 153 is located below or laterally of the display screen connector 151. The rotation driving device is optionally a servo motor, and an output end of the rotation driving device is in transmission connection with the display screen connecting piece 151 to drive the vehicle-mounted display screen 100 to rotate. The display screen connector 151 is in a ring shape, the display screen connector 151 is configured to have a circular central channel 152, and accordingly, the mount 110 has a mount through hole 119, and the mount through hole 119 is disposed corresponding to the central channel 152 for the wire harness of the vehicle-mounted display screen 100 to extend through the mount 110. Of course, in an embodiment not shown, the mount through holes and/or the central channel 152 may not be provided for a wireless set-up vehicle display screen. The display screen rotating assembly 150, the second transmission gear 131 and the roll-over stand hinge 132 are all integrally arranged on the roll-over stand 130, so that high integration of parts is realized, the number of parts is reduced, the structure is compact, and the development cost is reduced.

Referring to fig. 6 and 8, the fixing frame 110 is provided with a side rotation driving device 111. The mount 110 includes a first surface 120 for attachment to a vehicle and a second surface 121 opposite the first surface 120, the second surface 121 being configured with a recess 122 recessed toward the first surface 120 to at least partially house a second drive gear 131. The first surface 120 of the fixing frame 110 has a gear receiving portion 123 receiving the first driving gear 112 and a gear cover 124 covering the gear receiving portion 123 in an axial direction of the first driving gear 112, the gear cover 124 being detachably coupled to the gear receiving portion 123 by a fastener such as a bolt or the like to protect the first driving gear 112. And, the second transmission gear 131 can be smeared with lubricating oil when being installed, so as to reduce the friction force between the second transmission gear 131 and the gear cover 124, and prevent the gear cover 124 from influencing the rotation of the second transmission gear 131 when the upper part of the first transmission gear 112 is limited.

Referring to fig. 6, the second transmission gear 131 is configured as a sector-shaped incomplete gear, and the second transmission gear 131 is located above the gear housing 123 and below the gear cover 124. The side-turning drive 111 comprises a motor 113 and an output shaft connected to the motor 113, the output shaft being meshed to a third transmission gear, the output shaft being configured as a worm 114, the third transmission gear being configured as a worm wheel 115, the third transmission gear and the first transmission gear 112 being coaxially arranged and interconnected. The structure of the worm gear can realize self-locking. The third transmission gear (worm gear 115) and the first transmission gear 112 which are coaxially arranged can reduce the rotation speed, and have good transmission strength and rigidity, and the transmission is stable.

At the second surface 121 of the mount 110, there is a driving device accommodating portion 125 accommodating the side rotation driving device 111, the driving device accommodating portion 125 being closer to the side edge of the mount 110 than the gear accommodating portion 123. This results in a more compact structure.

As shown in connection with fig. 5, the motor 113 is penetrated to the driving device accommodating part 125, and an end of the worm 114 is rotatably connected to an inner wall of the driving device accommodating part 125. The worm wheel 115 and the first transmission gear 112 are disposed in the gear housing 123. Wherein, the axis of the first transmission gear 112 is parallel to the axis of the second transmission gear 131, and the axis of the second transmission gear 131 coincides with the axis of the hinge shaft 126, so as to prevent the second transmission gear 131 from interfering with the inner wall of the recess 122 when rotating, and also keep the second transmission gear 131 meshed with the first transmission gear 112.

When the motor 113 is started by receiving the signal, the motor 113 drives the worm 114 to rotate, so that the worm wheel 115 and the first transmission gear 112 rotate, and thus the second transmission gear 131 is driven to rotate, so that the roll-over stand 130 rotates around the hinge shaft 126, and the vehicle-mounted display screen 100 is arranged on the roll-over stand 130, so that the vehicle-mounted display screen 100 realizes side rotation. In the illustrated embodiment, the hinge shaft 126 is located at the left end, which is easily understood to be a design corresponding to a left rudder vehicle type. The turning mechanism for the right rudder vehicle model may be integrally mirror-image-arranged with the illustrated turning mechanism for the left rudder vehicle model.

And the rotating mechanism of the vehicle-mounted display screen according to the present utility model further comprises an elastic member 140, the elastic member 140 may be a spring, and both ends of the elastic member 140 are respectively connected to the fixed frame 110 and the roll-over stand 130, for applying a force to the roll-over stand 130 toward the retracted position, so that a gap between the first transmission gear 112 and the second transmission gear 131 is eliminated, and transmission efficiency between the first transmission gear 112 and the second transmission gear 131 is ensured.

Further, referring to fig. 1, the present utility model discloses a vehicle including a turning mechanism according to the above-described in-vehicle display screen, and an in-vehicle display screen 100 connected to the turning mechanism.

According to the vehicle of the second aspect of the present utility model, having the functions of turning and rotating the display screen 100 sideways, the visible angle of the driver and the passengers is improved, and the user experience is improved.
