Description

Technical Field

[0001] This invention relates to the field of automotive applications, and more particularly to a retractable, rotatable, and omnidirectional adjustment device, a display device, and an automobile. Background Technology

[0002] Currently, the fixed positions of displays on public transportation are no longer sufficient to meet the diverse viewing needs of users. Whether it's the displays on the back of cars, the small screens on the backs of airplane seats, or the advertising information screens in subway and bus carriages, their fixed height and angles are quite rigid.

[0003] This directly leads to numerous inconveniences: taller passengers may need to look down for extended periods, easily causing neck discomfort; while shorter passengers or children may be forced to look up, also experiencing fatigue. Furthermore, due to different seating positions, side or excessively far displays can cause severe viewing angle deviations and glare, significantly impacting viewing clarity and information acquisition.

[0004] In today's pursuit of personalized and comfortable experiences, this "one-size-fits-all" design approach is outdated and significantly impacts passenger travel experiences. Therefore, how to leverage technological or design innovation to give displays a degree of adjustability, enabling them to proactively adapt to different users' viewing positions and habits, has become a crucial aspect urgently needing improvement in enhancing public transportation service quality. Optimizing the human-computer interaction design of displays is an important step towards a more comfortable and convenient travel experience. Summary of the Invention

[0035] Unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as encompassing rather than being exclusive or exhaustive; that is, meaning "including but not limited to."

[0036] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0037] This invention provides a retractable, rotatable, and omnidirectional adjustment device for fixing a display screen and adjusting its position. The adjustment device includes a telescopic mechanism, a tilting mechanism, a flipping mechanism, and a rotating mechanism connected in sequence. The rotating mechanism is used to fix the display screen and can drive the display screen to rotate about the X-axis. The rotating mechanism is connected to the flipping mechanism and flips about the Y-axis under the drive of the flipping mechanism. The flipping mechanism is connected to the tilting mechanism and tilts about the Z-axis under the drive of the tilting mechanism. The tilting mechanism is slidably fixed to the telescopic mechanism, and the tilting mechanism, the flipping mechanism, and the rotating mechanism move along the X-axis, Y-axis, or Z-axis under the drive of the telescopic mechanism. In the reset state, the X-axis, Y-axis, and Z-axis... The Y-axis and Z-axis are mutually perpendicular; the flipping mechanism includes a first housing, a first driving component, a first transmission assembly, and a flipping shaft, wherein the first driving component and the first transmission assembly are housed within the first housing; the first driving component drives the first transmission assembly to operate, thereby causing the flipping shaft, which is fixedly connected to the first transmission assembly, to rotate; the first housing includes a first part and a second part that are mutually perpendicular, the first part being connected to the oscillation mechanism, and the second part being disposed close to the rotation mechanism; one end of the flipping shaft extends into the second part and is fixedly connected to the first transmission assembly, and the portion of the flipping shaft exposed outside the first housing is fixedly connected to the rotation mechanism; the flipping mechanism also includes a connecting body, one end of which is rotatably connected to the portion of the flipping shaft exposed outside the first housing, and the other end being fixedly connected to the first part.

[0038] First, the adjustment device provided by this invention cleverly integrates a telescopic mechanism, a swaying mechanism, a flipping mechanism, and a rotating mechanism into one unit, providing telescopic, swaying, flipping, and rotating movements for the display screen mounted on it. This allows the display screen to telescopically extend, rotate, and oscillate in all directions, providing users with an ideal viewing angle. Second, the configuration of the connection relationships between the telescopic mechanism, swaying mechanism, flipping mechanism, and rotating mechanism allows the adjustment device to not only provide a wide range of adjustment angles but also achieve a compact structure and small size. Third, since the first housing of the flipping mechanism includes a first part and a second part that are perpendicular to each other, one end of the flipping shaft extends into the second part and is fixedly connected to the first transmission component in the flipping mechanism. The part of the flipping shaft exposed outside the first housing is fixedly connected to the rotating mechanism and rotatably connected to one end of the connecting body. The other end of the connecting body is fixedly connected to the first part. This structural design ensures that the flipping movement of the display screen is stable and reliable.

[0039] Please see Figures 1 to 3 This invention provides a retractable, rotatable, and omnidirectional adjustment device 10, which is used to fix a display screen and adjust the position of the display screen. The specific way to adjust the position of the display screen includes, but is not limited to, one or more combinations of retraction, swaying, flipping, and rotation.

[0040] The adjustment device 10 includes a telescopic mechanism 11, a tilting mechanism 13, a flipping mechanism 15, and a rotating mechanism 17 connected in sequence. The telescopic mechanism 11, tilting mechanism 13, flipping mechanism 15, and rotating mechanism 17 can respectively drive the display screen to telescopicate, tilt, flip, and rotate. The rotating mechanism 17 is used to fix the display screen and can drive the display screen to rotate around the X-axis. The rotating mechanism 17 is connected to the flipping mechanism 15, and under the drive of the flipping mechanism 15, the rotating mechanism 17 flips around the Y-axis, thereby driving the display screen to flip around the Y-axis. The flipping mechanism 15 is connected to the tilting mechanism 13, and under the drive of the tilting mechanism 13, the flipping mechanism 15 and the rotating mechanism 17 tilt around the Z-axis, thereby driving the display screen to tilt around the Z-axis. The sway mechanism 13 is slidably fixed to the telescopic mechanism 11. The sway mechanism 13, the flipping mechanism 15 and the rotating mechanism 17 move in the X-axis, Y-axis or Z-axis direction under the drive of the telescopic mechanism 11, thereby driving the display screen to move in the X-axis, Y-axis or Z-axis direction.

[0041] It is understood that in the reset state, the X-axis, Y-axis, and Z-axis are mutually perpendicular. The reset state means that the X-axis and Y-axis are parallel to the horizontal plane, and the Z-axis is parallel to the vertical direction. In some embodiments, the reset state can be used as the initial power-on state or the power-off state. For example, when the display receives a power-off command, the control adjustment device 10 operates so that the X-axis and Y-axis are parallel to the horizontal plane, and the Z-axis is parallel to the vertical direction.

[0042] As one embodiment, the telescopic mechanism 11 can drive the sway mechanism 13, the flipping mechanism 15 and the rotating mechanism 17 to move in the X-axis direction, thereby driving the display screen to move in the X-axis direction. Here, the X-axis position is the position of the X-axis in the reset state, that is, the telescopic mechanism 11 can drive the display screen to move in the horizontal direction.

[0043] Please see Figures 1 to 5 The flipping mechanism 15 includes a first housing 151, a first driving member 152, a first transmission assembly 153, a flipping shaft 154, and a connecting body 155. The first driving member 152 and the first transmission assembly 153 are housed within the first housing 151. The flipping shaft 154 is partially located inside the first housing 151 and partially located outside the first housing 151. The end located inside the first housing 151 is fixedly connected to the first transmission assembly 153, and the portion located outside the first housing 151 is connected to the rotating mechanism 17 and the connecting body 155. The first driving member 152 drives the first transmission assembly 153 to work, and the first transmission assembly 153 drives the flipping shaft 154 to rotate, thereby driving the rotating mechanism 17 to flip, and the display screen fixed on the rotating mechanism 17 flips accordingly.

[0044] The first housing 151 includes a first portion 1511 and a second portion 1512 that are perpendicular to each other. It is understood that the first portion 1511 and the second portion 1512 are generally defined by their shapes. In some embodiments, the first portion 1511 and the second portion 1512 may also be physically separable. In some embodiments, the first portion 1511 and the second portion 1512 are integrally connected. In the illustration, the first portion 1511 and the second portion 1512 are integrally connected. The first portion 1511 is connected to the yaw mechanism 13, and the second portion 1512 is disposed near the rotation mechanism 17. In some embodiments, the first portion 1511 is connected to the yaw mechanism 13 via an "L"-shaped connector 137.

[0045] As one embodiment, the first part 1511 extends along the Y-axis direction, and the second part 1512 extends along a direction perpendicular to both the Y-axis and the Z-axis; that is, in the reset state, the second part 1512 extends along the X-axis direction. The first housing 151 is divided into two mutually perpendicular parts, which helps to reduce the product size, improve the product integration, and facilitate the setting of connectors 155, etc., to ensure the stability of the flipping.

[0046] As one embodiment, in the Z-axis direction, the height of the first portion 1511 is less than the height of the second portion 1512, which facilitates accommodating the first drive member 152 in the first portion 1511 and the first transmission assembly 153 in the second portion 1512. The bottoms of the first portion 1511 and the second portion 1512 are flush, which facilitates the configuration of the connector 155 and avoids mutual interference between the components.

[0047] As one embodiment, the first portion 1511 has the largest dimension in the Y-axis direction, and the second portion 1512 has the largest dimension in the X-axis direction in the reset state. Viewed in the Z-axis direction, the first housing 151 is L-shaped.

[0048] As one embodiment, the first drive member 152 is substantially housed within the first portion 1511, and the first transmission assembly 153 is substantially housed within the second portion 1512. The term "substantially housed" can be understood as more than half of the component being housed within the first portion 1511 or the second portion 1512.

[0049] In one embodiment, the first driving element 152 is a motor or other power source that can provide rotational power. The first transmission assembly 153 includes a plurality of gears that mesh with each other to transmit the rotational power of the first driving element 152 to a rotating shaft 154 connected to the first transmission assembly 153. The rotating shaft 154 is fixed at the axis of the gears at the end of the power transmission.

[0050] As one embodiment, the end plate 1511a of the first part 1511 away from the second part 1512 is detachable, and the side panel 1512a of the second part 1512 away from the side where the connector 155 is located is detachable, so as to facilitate the installation of the first drive member 152 and the first transmission assembly 153.

[0051] In one embodiment, one end of the flip shaft 154 is fixedly connected to the first transmission assembly 153, and the portion exposed outside the first housing 151 is fixedly connected to a rotating mechanism 17. During rotation, the flip shaft 154 can drive the rotating mechanism 17 to rotate around the flip shaft 154 as the axis. In this invention, the extension direction of the flip shaft 154 is the Y-axis direction.

[0052] As one embodiment, the flip shaft 154 passes through the second part 1512 and uses the second part 1512 as a mechanical support point. The gear in the first transmission assembly 153 connected thereto can be suspended and fixed on the flip shaft 154.

[0053] As one embodiment, the contact position between the flip shaft 154 and the first housing 151 is located at 2 / 5 to 3 / 5 of the height of the first housing 151, and further at 1 / 2 to 3 / 5 of its height, with the height of the first housing 151 in the Z-axis direction.

[0054] As one embodiment, one end of the connector 155 is rotatably connected to the portion of the flip shaft 154 exposed outside the first housing 151, and the other end is fixedly connected to the first part 1511. By providing the connector 155 between the flip shaft 154 and the first part 1511 of the flip mechanism 15, the stability of the flipping is greatly improved.

[0055] In one embodiment, the connection between the flip shaft 154 and the connecting body 155 is located at the end of the flip shaft 154 away from the first transmission component 153. In some embodiments, the end of the flip shaft 154 away from the first transmission component 153 is provided with a damping structure 156 to make the flipping smoother, and one end of the connecting body 155 is connected to the damping structure 156 to achieve a rotatable connection with the portion of the flip shaft 154 exposed in the first housing 151.

[0056] Please see Figure 6 In one embodiment, the connector 155 includes a plate 1550, a first extension plate 1551 and a second extension plate 1552 that are parallel to each other. The first extension plate 1551 and the second extension plate 1552 are vertically fixed at diagonal points on the upper surface of the plate 1550. The first extension plate 1551 is fixedly connected to the first part 1511, and the second extension plate 1552 is connected to the end of the flip shaft 154 away from the first transmission assembly 153. In some embodiments, it is connected to the damping structure 156. The structural design of the connector 155 ensures mechanical strength while avoiding interference with other components.

[0057] As one embodiment, the plate 1550 included in the connecting body 155 extends in a horizontal direction, that is, the plane containing the extension direction of the plate 1550 is perpendicular to the Z-axis. In some embodiments, the dimension of the plate 1550 in the Y-axis direction is greater than or equal to 70%*M, and the dimension in the X-axis direction in the reset state is greater than 75%*N, where M is the dimension of the rotating mechanism 17 in the Y-axis direction, and N is the distance between the second part 1512 and the rotating mechanism 17. Under these dimensional parameters, the mechanical strength of the flipping mechanism 15 can be better guaranteed, the flipping stability can be improved, and the weight distribution can be balanced.

[0058] In some embodiments, the connector 155 further includes a first reinforcing plate 1553 and a second reinforcing plate 1554. The first reinforcing plate 1553 is perpendicular to the plate body 1550 and the first extension plate 1551, and is connected to the plate body 1550 and the first extension plate 1551. The second reinforcing plate 1554 is perpendicular to the plate body 1550 and the second extension plate 1552, and is connected to the plate body 1550 and the second extension plate 1552. The first reinforcing plate 1553 and the second reinforcing plate 1554 can improve the mechanical strength of the connector 155, which is more conducive to ensuring the stability of the flipping.

[0059] As one embodiment, the distance between the second extension plate 1552 and the second part 1512 is greater than the dimension of the rotating mechanism 17 in the Y-axis direction to avoid interference during the flipping process.

[0060] As one embodiment, in the Z-axis direction, the plate 1550 is positioned lower than the flip axis 154 to avoid interference with the rotation mechanism 17.

[0061] As one embodiment, the position where the flipping shaft 154 is connected to the rotating mechanism 17 is located at 2 / 5 to 3 / 5 of the height of the rotating mechanism 17, which is beneficial to maintaining flipping stability. The height direction of the rotating mechanism 17 is the Z-axis direction.

[0062] As one embodiment, the X-axis and Z-axis form an XZ plane. The projections of the first part 1511 and the connecting body 155 in the XZ plane overlap with the projections of the second part 1512 in the XZ plane. That is, the first part 1511 and the connecting body 155 are located on one side of the second part 1512, which is beneficial to reduce the product size.

[0063] As one embodiment, the connecting body 155 and the rotating mechanism 17 are located on opposite sides of the flip shaft 154.

[0064] As one embodiment, the connection position between the first part 1511 and the connector 155 is located on the side of the first part 1511 near the flip shaft 154.

[0065] As one embodiment, the first part 1511, the connecting body 155, and the rotating mechanism 17 are located on the same side of the second part 1512.

[0066] Under one or more of the aforementioned positions and parameters, the flipping mechanism 15 not only achieves a compact structure but also ensures flipping stability.

[0067] As one embodiment, a second detector 1541 is fixed on one end face of the flip shaft 154 located in the second part 1512, for detecting the rotation angle of the flip shaft 154, and thus determining the flip angle of the display screen.

[0068] As one embodiment, the first transmission component 153 includes several helical gears with different radial dimensions and several spur gears with different radial dimensions. The helical gears and spur gears mesh sequentially so that the power transmission direction is changed by the helical gears and then the power is transmitted to the flip shaft 154 by the spur gears.

[0069] In one specific embodiment, the first transmission assembly 153 includes a first helical gear 153a, a second helical gear 153b, a third helical gear 153c, a fourth helical gear 153d, a first spur gear 153e, and a second spur gear 153f that mesh with each other in sequence. The second helical gear 153b and the third helical gear 153c, which have different radial gears, are coaxially fixed. The fourth helical gear 153d and the first spur gear 153e are coaxially fixed.
