[0029] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely exemplary of specific ways to implement and use the present disclosure, and are not intended to limit the scope of the present disclosure. When describing the structural positions of the various components, such as up, down, top, bottom, etc., the expressions of directions are not absolute, but relative. When the various components are arranged as shown in the figure, these directional expressions are appropriate, but when the positions of the various components in the figure change, these directional expressions also change accordingly.
[0030] Herein, “front”, “rear”, “up” and “down” are defined according to the actual direction of the vehicle, wherein “front” and “rear” are relative to the forward direction of the vehicle.
[0031] Herein, the terms “first”, “second” and the like are not used to limit the order of precedence and the number of components unless otherwise specified.
[0032] In this document, unless otherwise specifically defined, the terms "installation", "connection", "attachment" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in this document can be understood according to the specific circumstances.
[0033] It should be understood that the multi-directional moving mechanism for an on-vehicle display screen and the on-vehicle display screen system of the present disclosure are applicable to various appropriate transportation tools, and the term "transport tool" includes but is not limited to vehicles, ships, airplanes, etc., wherein "vehicle" includes fuel vehicles, hybrid vehicles, electric vehicles, hydrogen-powered vehicles, etc., and can be various types of vehicles, such as small cars, buses, rail vehicles, etc. In the following, the application environment of the multi-directional moving mechanism and the on-vehicle display screen system is mainly described in terms of vehicles such as small cars, but it does not exclude that the present disclosure can be applied to other types of transportation tools.
[0034] It has been recognized that while the existing ceiling-mounted display screens of vehicles provide flipping and / or translation functions, the driving mechanism (such as the hinge mechanism) occupies a large space and has the problem of being exposed during use, affecting the comfort of the passengers. In addition, the driving mechanism that provides the flipping and / or translation functions is usually distributed on both sides of the display screen, thereby limiting the width and movement range of the display screen. In addition, the driving mechanism of the existing display screen can only flip and / or translate in the front and rear directions of the vehicle, and cannot achieve multi-directional movement adjustment, and thus cannot meet the growing user needs.
[0035] According to the concept of the present disclosure, a multi-directional moving mechanism for a vehicle display screen and a vehicle display screen system using the multi-directional moving mechanism are provided, so as to realize the flipping and / or translation of the vehicle display screen in multiple directions. Figure 1 The vehicle-mounted display screen system is arranged on the top of the vehicle, such as a roof sheet metal or a roof decoration. In the illustrated embodiment, the vehicle-mounted display screen system includes a frame 100 and a crossbeam 200 attached to the frame 100, and a rotating device 300 attached to the crossbeam 200, and the vehicle-mounted display screen 400 is installed on the rotating device 300. The frame 100 is suitable for being attached to the top of the vehicle, for example, in some embodiments, the frame 100 can be constructed as a part of the roof sheet metal.
[0036] According to the present disclosure, the frame 100 defines a moving range in a substantially rectangular shape, the crossbeam 200 extends along a first direction and is attached to the frame 100, and is configured to be able to translate in a second direction along the frame 100 within the moving range, the second direction being perpendicular to the first direction, and the rotating device 300 is able to translate in the first direction along the crossbeam 200. In some embodiments, the first direction is parallel to the width direction of the vehicle, such as Figure 1 The second direction is parallel to the length direction of the vehicle or the front and rear direction of the vehicle, such as Figure 1 The vehicle-mounted display screen 400 is oriented in the X direction so that the vehicle-mounted display screen 400 can be translated in the front-rear direction of the vehicle and / or the width direction of the vehicle, wherein the vehicle-mounted display screen 400 is generally oriented in the open state. Figure 1 The rear space behind the vehicle in the lower left corner.
[0037] Advantageously, see Figure 2C The rotating device 300 includes a first rotating component 310 and a second rotating component 320 attached to each other, and the first rotating component 310 is configured to drive the vehicle-mounted display screen 400 to rotate around a first direction to be in a closed state or an open state. Figure 1 The second rotating assembly 320 is configured to drive the vehicle-mounted display screen 400 in the open state to rotate around a third direction, which is perpendicular to the first direction and / or the second direction. In the embodiment shown, the third direction is a vertical direction, such as Figure 1 In this way, the vehicle-mounted display screen 400 can not only translate in the front-rear direction of the vehicle and / or the width direction of the vehicle, but also rotate or flip around the first direction and / or the vertical third direction, effectively meeting the vehicle occupants' needs for adjusting the position of the vehicle-mounted display screen and the tilt angle in the open state in different occasions, thereby improving the user experience.
[0038] FIG. 2A to FIG. 2C The in-vehicle display screen 400 is shown to be in a closed state. In this state, the in-vehicle display screen 400 is substantially parallel to the top of the vehicle, so as to be stored in the top of the vehicle, for example, at a position biased toward the rear of the vehicle (the rear space of the vehicle).
[0039] FIG. 3A to FIG. 3B The vehicle display screen 400 is shown in an open state and compared to FIG. 2A to FIG. 2C In the position shown, the crossbeam 200 moves in the second direction (X direction) along the frame 100. In this state, the vehicle-mounted display screen 400 is rotated and unfolded around the first direction (Y direction) by the first rotating assembly 310 to be substantially perpendicular or angled to the top of the vehicle, and can be translated to a desired position in the front-rear direction of the vehicle to meet the use needs of the occupants.
[0040] FIG. 4A to FIG. 4C The vehicle display screen 400 is shown in an open state and compared to FIG. 3A to FIG. 3B In the position shown, the cross beam 200 moves along the frame 100 in the second direction (X direction) and the rotating device 300 moves along the cross beam 200 in the first direction (Y direction). In this way, the vehicle-mounted display screen 400 can be adjusted to a position facing a specific occupant to meet the usage requirements of different occupant positions.
[0041] FIG. 5A to FIG. 5C The vehicle display screen 400 is shown in an open state and compared to FIG. 4A to FIG. 4C The position shown is rotated around the third direction (Z direction) by the second rotating assembly 320. In this way, the vehicle-mounted display screen 400 can not only meet the use requirements of a specific passenger position, but also realize certain additional functions. For example, when the vehicle-mounted display screen 400 is rotated and adjusted to face the outside of the vehicle, a welcome message can be displayed when the passenger enters the vehicle.
[0042] The following describes the implementation of the multi-directional movement mechanism of the present invention. Figures 2A to 5C The specific methods of each state.
[0043] First, see Figure 2C , Figure 6 and Figure 7 The frame 100 is provided with a first guide rail 110 arranged along the second direction, and correspondingly, the crossbeam 200 is provided with a first slider 210 adapted to be driven by the first driving motor 120 to move along the first guide rail 110. Figure 7 Different moving positions of the crossbeam 200 are illustrated in solid and dashed lines. In some embodiments, the first drive motor 120 may be arranged on the frame 100, for example, at a position on the frame 100 that is offset from the first guide rail 110, such as Figure 6 In this way, the driving mechanism for realizing the translation of the vehicle-mounted display screen 400 along the second direction is hardly exposed inside the vehicle visible to the passengers. Figure 2A and Figure 2B As shown, the vehicle-mounted display screen system has an aesthetically pleasing exterior shape and can significantly improve the size of the occupied space in the vertical direction (Z direction).
[0044] Combination Figure 4C , Figure 6 and Fig.9A In some embodiments, the crossbeam 200 is provided with a rack 342 arranged along a first direction, and the rotating device 300 includes a first gear 343, which can be driven by a second driving motor 341 ( Fig.9A ) is driven to mesh with the rack 342, so that the rotating device 300 is translated along the first direction on the beam 200. Depending on different needs, the rack 342 can extend along a partial length or the entire length of the beam 200. Advantageously, the second drive motor 341 can be arranged on the rotating device to facilitate a compact layout of various components.
[0045] As described above, the vehicle-mounted display screen 400 is installed on the rotating device 300, and the rotating device 300 includes a first rotating component 310 and a second rotating component 320 attached to each other to realize the rotation of the vehicle-mounted display screen 400 around the first direction and / or the third direction. Figure 6 , FIG. 8A to FIG. 8B In some embodiments, the first rotating assembly 310 includes a third driving motor 311, a second guide rail 312 arranged along the second direction, and a second slider 313 and a third slider 314 that are adapted to be driven by the third driving motor 311 to be wedged with each other and move on the second guide rail 312 along the second direction. In this way, when the second slider 313 and the third slider 314 are wedged, the vehicle-mounted display screen 400 can be in a closed state and locked, and when the second slider 313 and the third slider 314 are disengaged and move on the second guide rail 312 along the second direction, the vehicle-mounted display screen 400 can be unlocked and can rotate around the first direction, which advantageously ensures the locking stability of the vehicle-mounted display screen in the closed state, eliminates the accidental deployment of the vehicle-mounted display screen or even equipment damage caused by misoperation in a manual operation mode, and avoids the space and cost problems caused by using an additional motor to control the locking component.
[0046] In some embodiments, the second slider 313 may be provided with a wedging groove 315, and the third slider 314 may be provided with a wedging block 316 accordingly. Fig. 8A When the position shown in FIG. 1 is moved toward the left, that is, toward the rear of the vehicle (the rear space of the vehicle), on the second guide rail 312, the wedging block 316 can be separated from the wedging state with the wedging groove 315, so that the vehicle-mounted display screen 400 is unlocked and can be rotated around the first direction to Figure 8B On the contrary, when the second slider 313 and the third slider 314 are driven by the third driving motor 311 to Figure 8B When the position shown in FIG. 1 is moved toward the right, that is, toward the front of the vehicle, on the second guide rail 312, the wedging block 316 can be moved and embedded in the wedging groove 315 so that the second slider 313 and the third slider 314 are wedged with each other. During this period, the vehicle-mounted display screen 400 rotates around the first direction to Fig. 8A In the closed state shown, the wedging second slider 313 and the third slider 314 can keep the vehicle display screen 400 in the closed state locked. In other words, the movement of the vehicle display screen rotating around the first direction to be in the open state can only be implemented after the wedging effect between the sliders is released; conversely, the wedging locking between the sliders can only be realized after the vehicle display screen is rotated to the right position to be in the closed state, which can be achieved by setting the size and position relationship of the slider, the guide rail, and the connecting parts between the first rotating component and the vehicle display screen according to different actual needs, which will not be described in detail here.
[0047] In some embodiments, the vehicle-mounted display screen 400 is connected to the rotating device 300 via a display screen bracket 410. Figure 6 , Fig. 8A and Figure 8B The display screen bracket 410 includes a connecting rod 411 and a pivot rod 412, and the connecting rod 411 can be connected to the vehicle-mounted display screen 400 by means of fasteners or bonding, for example. One end of the connecting rod 411 is pivotally connected to the rotating device 300, preferably the second rotating assembly 320, through a first pivot shaft 413, so as to be suitable for realizing rotation around a third direction, which will be described below. The pivot rod 412 can be pivotally connected between the connecting rod 411 and the first rotating assembly 310 through a second pivot shaft 414 and a third pivot shaft 415, respectively. Advantageously, the pivot rod 412 can be linked with the second slider 313 and the third slider 314, for example, it can be pivotally connected to one of the second slider 313 and the third slider 314 directly or through an intermediate piece. When the second slider 313 and the third slider 314 move on the second guide rail 312 along the second direction, one end of the pivot rod 412 can pivot around the third pivot axis 415, and then the other end pivots around the second pivot axis 414 to realize the rotation of the connecting rod 411, that is, the rotation of the vehicle-mounted display screen 400. In this way, the rotation movement of the vehicle-mounted display screen is easy to implement, low in cost and has the advantages of small size, which is particularly beneficial to the application environment of small space on the top of the vehicle.
[0048] from Fig. 8A and Figure 8B It can be seen that in some embodiments, the other end of the connecting rod 411 away from the first pivot axis 413 may be provided with a hook 416, and the second guide rail 312 may be provided with a corresponding buckle 317. In this way, the vehicle-mounted display screen in the closed state can be further locked by engaging the hook 416 and the buckle 317 with each other.
[0049] When the vehicle-mounted display screen 400 rotates around the first direction to be in the open state, Figure 6 , Fig.9A and Fig. 9B In some cases, the vehicle-mounted display screen 400 can be rotated to a desired position around the third direction through the second rotating assembly 320. In some embodiments, the second rotating assembly 320 can be attached to the second guide rail 312 to help reduce the occupied space of the rotating device 300, and includes a fourth drive motor 321 and a fourth slider 322, and the fourth slider 322 can be driven by the fourth drive motor 321 to rotate around the third direction. As described above, the display screen bracket 410 is advantageously attached to the second rotating assembly 320, so that the rotation of the fourth slider 322 can cause the vehicle-mounted display screen 400 to rotate around the third direction.
[0050] In some embodiments, the fourth slider 322 is configured as an arc-shaped toothed disc and is mounted on the second guide rail 312, for example, through an arc-shaped frame 323 that matches its shape. The display bracket 410 is suitable for being mounted on the arc-shaped frame 323 and linked therewith. The second rotating assembly 320 further includes, for example, a second gear 324 disposed on the second guide rail 312. When the vehicle-mounted display screen 400 needs to be moved from Fig.9A When the second gear 324 rotates around the third direction in the state shown, the second gear 324 can be driven by the fourth driving motor 321 to engage with the fourth slider 322 in the form of a toothed disc so that the toothed disc rotates around the third direction, thereby rotating the vehicle-mounted display screen 400 to Fig. 9B status shown and vice versa.
[0051] In some embodiments, the rotating device 300 may include a mounting bracket 330, in combination with Figure 6 , Figure 8B and Fig.9A , the first rotating assembly 310 and the second rotating assembly 320 can be mounted to the mounting bracket 330 and attached to the crossbeam 200 via the mounting bracket 330. In addition, the mounting bracket 330 can carry a driving motor (a second driving motor 341) that drives the rotating device 300 to translate in the first direction, and a driving motor (a third driving motor 311, a fourth driving motor 321) that drives the first rotating assembly 310 and the second rotating assembly 320. In this way, the driving mechanism for realizing the translation of the vehicle-mounted display screen 400 along the first direction and the driving mechanism for rotating around the first direction and the third direction are integrated in the area of the rotating device 300, and do not interfere with the movement of the vehicle-mounted display screen. The vehicle-mounted display screen system has a beautiful exterior shape, a compact structure, and no exposed driving components, which can significantly improve the size of the occupied space in the vertical direction (Z direction), such as Figure 2A and Figure 2B shown.
[0052] The multi-directional moving mechanism of the vehicle display screen system disclosed in the present invention effectively realizes the translation of the vehicle display screen in the first direction and the second direction, the rotation around the first direction and the third direction, and the locking function in the closed state with a compact layout, thereby reducing the overall size while reducing the cost. Even when the vehicle is driving, it can maintain stability in use and avoid damage caused by human misoperation, and the application is safe and reliable.
[0053] It should be understood here that the embodiments shown in the figures only show the optional shapes, sizes and arrangements of the multi-directional moving mechanism and the vehicle-mounted display screen system for the vehicle-mounted display screen according to the present disclosure. They are only for illustration and not for limitation. Other shapes, sizes and arrangements may also be adopted without departing from the concept and scope of the present disclosure.

However, it can be understood that under the creative ideas of the present disclosure, technicians in this field can make various changes and improvements to the above disclosed concepts, but they all belong to the protection scope of the present disclosure.
