DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] An embodiment of the present application discloses a vehicle-mounted display angle adjustment device.

[0036] Reference Figure 1 and Figure 2 The vehicle display angle adjustment device includes a housing 100, the housing 100 includes a chassis 110, an outer limit ring 120 is integrally formed on the chassis 110, a connecting ring 130 is fixedly connected to the inner edge of the outer limit ring 120, an inner limit ring 140 is fixedly connected to the inner edge of the connecting ring 130, the connecting ring 130 is arranged parallel to the chassis 110, the outer limit ring 120 and the inner limit ring 140 are both arranged perpendicular to the chassis 110, and a driving cavity 150 is formed between the outer limit ring 120 and the inner limit ring 140, an adapter flange 200 connected to the vehicle display 400 is rotatably connected to the housing 100, and a driving device 300 for driving the adapter flange 200 to rotate is arranged in the housing 100. In the embodiment of the present application, the vehicle display 400 can be directly connected to the adapter flange 200 by bolt installation, and the vehicle display 400 can also be indirectly connected to the adapter flange 200 through a screen adapter plate 410.

[0037] Reference Figure 2 The driving device 300 includes a power unit 310 and a deflection unit 320. The power unit 310 is located in the driving cavity 150 and is used to provide a power source for the deflection unit 320. The output end of the deflection unit 320 is connected to the adapter flange 200. Therefore, the power unit 310 is arranged in the driving cavity 150 in the housing 100. After the deflection unit 320 outputs power, it is connected to the adapter flange 200 to drive the vehicle display 400 to deflect, thereby reducing the size of the overall vehicle display angle adjustment device, meeting the arrangement requirements of the narrow space in the vehicle dashboard, and improving the space utilization rate in the dashboard.

[0038] Reference Figure 2 The power unit 310 includes a stator ring 311 bonded to the inner limit ring 140 and coaxially arranged with the inner limit ring 140. A control panel 312 is connected to the chassis 110. In the embodiment of the present application, the control panel 312 can adopt a PCB board. The stator ring 311 is used to generate a magnetic field and drive the deflection unit 320 to rotate when powered on. The control panel 312 is used to control the power-on state of the stator ring 311 and output the position information of the feedback vehicle display 400.

[0039] Reference Figure 2The deflection unit 320 includes a rotor assembly disposed on the inner edge of the inner stop ring 140. In the embodiment of the present application, the rotor assembly may include a rotor shaft 321 disposed on the inner edge of the inner stop ring 140, and the rotor shaft 321 directly outputs power to be directly connected to the vehicle-mounted display 400. A magnetic steel 324 is bonded to the inner wall of the rotor shaft 321. In the embodiment of the present application, the rotor shaft 321 is located at the inner edge of the stator ring 311, and the magnetic steel 324 in the rotor shaft 321 is coaxially arranged with the control panel 312, which reduces the possibility of increasing the height of the overall vehicle-mounted display angle adjustment device and improves space utilization.

[0040] Reference Figure 2 In the embodiment of the present application, the rotor assembly can also be configured as a turntable 322 fixedly connected to one end of the rotor shaft 321 facing the chassis 110, the turntable 322 is arranged parallel to the chassis 110, and the outer edge of the turntable 322 is fixedly connected to a swivel 323 arranged perpendicular to the turntable 322, the swivel 323 is located in the driving cavity 150, and the inner limit ring 140 is provided with a support assembly 330 for supporting the rotor shaft 321, and the rotor shaft 321 is rotatably connected to the support assembly 330. The swivel 323 is arranged in the driving cavity 150 in the housing 100, which reduces the size of the overall vehicle display angle adjustment device, meets the layout requirements of the narrow space in the vehicle dashboard, and improves the space utilization rate in the dashboard. The running stability of the rotor shaft 321 during rotation is improved, and the smooth deflection of the vehicle display 400 is ensured.

[0041] Therefore, the stator ring 311 is energized to generate a magnetic field under the control of the control panel 312, thereby generating a torque to drive the turntable 322, the rotating ring 323 and the rotor shaft 321 to rotate synchronously, forming an outer rotor motor structure, thereby driving the adapter flange 200 to rotate to achieve the deflection of the vehicle display 400. The outer rotor motor structure has the characteristics of low speed and high torque, stable operation, and good noise performance, which improves the operating efficiency of the overall vehicle display angle adjustment device while taking into account the viewing angles of users in different positions of the driver and the co-driver, reducing problems such as reflection and glare when users view the vehicle display 400.

[0042] Reference Figure 2The support assembly 330 includes a support plate 331 disposed on the inner stop ring 140, and the support plate 331 and the inner stop ring 140 are installed by interference fit. A mounting hole 332 matching the size of the rotor shaft 321 is provided on the support plate 331, and the rotor shaft 321 passes through the mounting hole 332. A first placement groove 333 is provided on the hole wall of the mounting hole 332, and a first bearing 334 is installed in the first placement groove 333. The outer ring of the first bearing 334 is fixedly disposed on the groove wall of the first placement groove 333, and the inner ring of the first bearing 334 is fixedly disposed on the rotor shaft 321. Therefore, the first bearing 334 bears axial and radial loads, provides support for the rotor shaft 321, and reduces the friction between the rotor shaft 321 and the support plate 331, reduces the wear of the rotor shaft 321, and improves the stability of the operation of the rotor shaft 321. The support plate 331 can also prevent impurities and debris from falling into the first bearing 334, thereby affecting the use of the first bearing 334.

[0043] Reference Figure 2 and Figure 3 , the rotor shaft 321 is connected to the adapter flange 200 through the reduction unit 340, and the reduction unit 340 is used to increase the output torque of the adapter flange 200 and reduce the output speed of the adapter flange 200. The reduction unit 340 includes a ring gear 341 arranged on the inner limit ring 140 and a sun gear 342 fixedly sleeved on the rotor shaft 321. The inner edge of the ring gear 341 is provided with a plurality of planetary gears 343 meshing with both the sun gear 342 and the ring gear 341. The plurality of planetary gears 343 are all located between the sun gear 342 and the ring gear 341. The adapter flange 200 is connected to the plurality of planetary gears 343. In the embodiment of the present application, the number of the planetary gears 343 is set to three. The ring gear 341, the sun gear 342 and the planetary gears 343 are all meshed with helical teeth. The helical teeth mesh more tightly than the straight teeth mesh, have a higher load-bearing capacity, and have good noise performance.

[0044] Therefore, when the rotor shaft 321 drives the sun gear 342 to rotate, it will drive the planetary gear 343 meshing with the sun gear 342 to rotate. The planetary gear 343 revolves around the sun gear 342 and rotates on itself, thereby driving the adapter flange 200 to rotate. The multi-tooth meshing structure enables the reduction unit 340 to withstand a larger load. The reduction unit 340 adopts a first-stage planetary reduction, and the reduction unit 340 is located at the inner edge of the positioning ring 311. The required space size is smaller and has a higher transmission efficiency. The reduction unit 340 is used to reduce the rotational speed of the yaw unit 320 when it outputs power. The use of a first-stage planetary reduction can reduce vibration and noise during operation and improve operational stability.

[0045] Reference Figure 2 and Figure 3, on the surface of the three planet gears 343 facing away from the chassis 110, there are connecting shafts 344 connected. The connecting shafts 344 are rotatably connected to the housing 100, and the three planet gears 343 are connected to the adapter flange 200 through the connecting shafts 344. The connecting shafts 344 convert the revolution motion of the planet gears 343 into the rotational motion of the adapter flange 200, providing a guiding effect for the force, so as to achieve the purpose of reducing speed and increasing torque.

[0046] Refer to Figure 2 and Figure 3 , on the inner peripheral wall of the inner limiting ring 140, there is a support ring 360 fixedly connected. The support ring 360 is coated with a self-lubricating damping bushing 350. The damping bushing 350 is pressed tightly between the adapter flange 200, the connecting shaft 344 and the support ring 360. In the embodiment of the present application, the damping bushing 350 adopts a C-shaped structure. The upper end surface of the damping bushing 350 is attached to the adapter flange 200, the lower end surface of the damping bushing 350 is attached to the flange surface of the connecting shaft 344 and the damping bushing 350 is pressed tightly between the support ring 360 and the connecting shaft 344. The damping bushing 350 can realize the adjustable axial and radial damping between the inner limiting ring 140 and the connecting shaft 344. By adjusting the axial interference amount of the upper end surface and the lower end surface of the damping bushing 350, the adjustment of the axial main damping value is realized; by adjusting the radial interference amount when the damping bushing 350 is installed, the adjustment of the radial secondary damping value is realized. The damping bushing 350 reduces the sliding friction between the adapter flange 200, the connecting shaft 344 and the support ring 360. The damping bushing 350 offsets the running clearance of the reduction unit 340, enabling the vehicle-mounted display 400 to hover at any position, improving the running stability. At the same time, the damping bushing 350 provides the damping force required when the vehicle-mounted display 400 is subjected to vibration impact, thereby reducing vibration, reducing the running noise and improving the running stability.

[0047] Refer to Figure 2 and Figure 3 , on the surface of the connecting shaft 344 facing the adapter flange 200, there is a second placement groove 345 opened. A limiting hole 347 is opened at the bottom of the second placement groove 345. A second bearing 346 is installed in the second placement groove 345. The outer ring of the second bearing 346 is fixedly arranged on the groove wall of the second placement groove 345. The rotor shaft 321 passes through the limiting hole 347 and the inner ring of the second bearing 346 is fixedly sleeved on the rotor shaft 321. In the embodiment of the present application, the first bearing 334 and the second bearing 346 are coaxially arranged. Therefore, the second bearing 346 bears axial and radial loads, provides a supporting effect on the rotor shaft 321 while reducing the friction between the rotor shaft 321 and the connecting shaft 344, reducing the wear of the rotor shaft 321 and improving the running stability of the rotor shaft 321.

[0048] Refer to Figure 2 and Figure 3A limiting groove 348 is provided on the outer edge of the rotor shaft 321, and a limiting block 349 matching the limiting groove 348 is installed in the limiting groove 348. The surface of the limiting block 349 facing the chassis 110 contacts the second bearing 346. The limiting block 349 in the embodiment of the present application adopts a retaining spring, which is compressed in the limiting groove 348 to ensure that the bearing does not generate axial displacement during operation. The retaining spring can also be used as a buffer to absorb and disperse the vibration and impact force generated by the bearing during movement, thereby reducing vibration and noise.

[0049] In addition, in the embodiment of the present application, if the output of the power unit 310 can meet the load requirements, the rotor shaft 321 can be directly connected to the vehicle-mounted display 400 to achieve the deflection of the vehicle-mounted display 400. After the structure of the reduction unit 340 is omitted, the height of the overall mechanism is further reduced, and the size of the overall vehicle-mounted display angle adjustment device is reduced, which meets the layout requirements of the narrow space in the vehicle dashboard and improves the space utilization rate in the dashboard.

[0050] The implementation principle of the embodiment of the present application is as follows: the stator ring 311 is energized to generate a magnetic field under the control of the control panel 312, thereby generating a torque to drive the turntable 322, the rotating ring 323 and the rotor shaft 321 to rotate synchronously. When the rotor shaft 321 drives the sun gear 342 to rotate, it drives the planetary gear 343 meshing with the sun gear 342 to rotate. The planetary gear 343 rotates while revolving around the sun gear 342, thereby driving the adapter shaft 344 to rotate in the housing 100. The adapter shaft 344 drives the adapter flange 200 connected to the vehicle-mounted display 400 to rotate, thereby The direction of the vehicle display 400 is deflected to take into account the viewing angles of users in different positions of the driver and the co-driver, reduce problems such as reflection and glare when users view the vehicle display 400, ensure the user's safe use while improving the user experience. Since the adapter shaft 344, the adapter flange 200, the control panel 312 and the rotor shaft 321 are all coaxially arranged, the size of the overall vehicle display angle adjustment device is reduced, meeting the layout requirements of the narrow space in the vehicle dashboard, improving the space utilization rate in the dashboard, and running smoothly while having good noise performance.
