Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a rotating mechanism for an in-vehicle display device. Background Technology

[0002] The use of in-vehicle intelligent interactive devices is becoming increasingly diversified. To better meet user needs, more and more passenger vehicles are equipped with in-vehicle displays or tablets that can rotate. A mechanism enables the display / tablet to switch between landscape and portrait modes.

[0003] For example, the "Display Device and Vehicle" disclosed in Chinese Utility Model Announcement No. CN215752217U includes a display screen with a connecting portion. The central axis of the connecting portion is located off-center from the geometric center of the display screen. A drive assembly includes a power unit and a transmission worm gear driven by the power unit. The transmission worm gear is driven by the connecting portion. The power unit generates power to drive the transmission worm gear, causing the connecting portion to rotate, thereby rotating and / or lifting the display screen around the central axis of the connecting portion. While the transmission worm gear connection of the connecting portion in the application allows a single power source to drive the display screen to rotate and lift different axes, the reduction gearbox and worm gear occupy a significant amount of space, making it unsuitable for use on thin and light displays or small tablet computers.

[0066] Exemplary embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that this application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, the same reference numerals denote the same or functionally identical elements.

[0067] refer to Figures 1 to 3 The rotating mechanism of the vehicle-mounted display device mainly includes: a rotating mechanism 200, a bracket 100, and an electric drive mechanism 300. A tablet computer 1 is also fixed to the front of the rotating mechanism 200.

[0068] refer to Figures 4 to 10The rotating mechanism 200 includes a driven disk cover 210, a driven disk 220, and a charging module 230. A hole 111 is formed in the upper wall panel 110 of the bracket. The driven disk cover 210 and the driven disk 220 are assembled and fixed by clamping them together through the hole 111 from both sides using a sandwich-like structure. After assembly, the driven disk 220 and the driven disk cover 210 can rotate synchronously in the hole 111. The charging module 230 is fixed to the back of the driven disk cover 210 and rotates with it to provide wireless charging for the tablet. Multiple mounting slots 211 are provided on the rear side of the driven disk cover 210, and magnets 212 are installed in the mounting slots 211.

[0069] The tablet computer 1 is magnetically attached to the front of the driven disk cover 210. To ensure that the tablet computer 1 is fixed in the designed position, the planar distribution of the mounting slots 211 is non-circular arc shape. A rear cover 130 is also provided on the support body 100, which is assembled from the rear to cover the internal parts of the rotating mechanism 200.

[0070] The electric drive mechanism 300 includes a motor 310, a shaft 330, a drive bracket 350, and a drive disc 320. The motor 310 and the drive disc 320 are fixed to the lower wall plate 120 of the bracket via the drive bracket 350, and the drive disc 320 is driven to rotate via the shaft 330.

[0071] A synchronization mechanism connects the electric drive mechanism 300 and the rotation mechanism 200 together, and transmits the torque output by the electric drive mechanism 300 to the rotation mechanism 200, causing the driven disk 220 to rotate.

[0072] In a first embodiment of the present invention, the synchronization mechanism is a cable 231. Two non-connected grooves 321 are respectively formed on the circumference of the driving disc 320, and the two ends of the cable 231 are wound into and fixed therein. A transmission part 232 with a protruding structure is provided on the cable 231, and a limiting part 222 is provided on the circumference of the driven disc 220, with the transmission part 232 inserted into the limiting part 222. The output of the electric drive mechanism 300 drives the driven disc 220 to rotate via the cable 231 through the driving disc 320.

[0073] A baffle plate 331 is fitted onto the shaft 330 and rotates accordingly. A stop point 351 is provided on the drive bracket 350. The baffle plate 331 will touch the stop point 351 at the end of the clockwise / counterclockwise rotation stroke, thereby limiting the rotation angle of the driving disk 320 and the driven disk 220. An adjusting wheel 340 is also provided on the bracket body 100. The adjusting wheel 340 is an eccentric wheel fixed by an eccentric shaft 342.

[0074] refer to Figures 11 to 16When the rotating mechanism of the present invention is in its initial state, the tablet computer 1 is located at the first position 2 on the rotating mechanism, and the baffle 331 is in contact with the right side of the stop point 351. When the motor 310 (see other figures) drives the shaft 330 to rotate, the baffle 331 rotates accordingly, and the driven disk 220 rotates counterclockwise under the pull of the transmission part 232, driving the tablet computer 1 to rotate from the first position 2 to the second position 3. When the baffle 331 contacts the left side of the stop point 351, the motor 310 stalls, and the rotation of the tablet computer 1 ends. In this embodiment, the first position 2 is the 12 o'clock position in a planar state, and the second position 3 is the 9 o'clock position. The adjusting wheel 340 tensions the cable 231 on one side through eccentric movement.

[0075] In one embodiment not listed, the first position 2 may be at the 3 o'clock, 6 o'clock, or 9 o'clock position, and the second position 3 is rotated 90° relative to the first position 2.

[0076] Reference Figure 17 In the second embodiment of the present invention, the synchronization mechanism is a synchronous belt 233 connecting the driving disk 320 and the driven disk 220 (the arrow indicates the direction of rotation), and the motor 310 is a Hall motor, which controls the rotation angle of the plate through the motor program.

[0077] Reference Figure 18 In the third embodiment of the present invention, the synchronization mechanism is a drive link 234, which transmits power between the electric drive mechanism 300 and the rotating mechanism 200 through a reduction gear and link structure.

[0078] refer to Figure 19 and Figure 20 In the fourth embodiment of the present invention, the rotating mechanism 200 is operated manually instead of by the electric drive mechanism 300. A gear ring 221 is provided circumferentially on the driven disk 220, and a damping element 250 is provided on the upper shaft of the bracket upper wall plate 110. The damping element 250 can be a damping gear, and the rotational speed of the driven disk 220 is controlled by the meshing of the damping element 250 with the gear ring 221.
