Description

Technical Field

[0001] The utility model belongs to the field of displays, and particularly relates to a hinge - flip type vehicle - mounted light - field display. Background Art

[0002] With the development of vehicle intelligence, the vehicle - mounted display system has become an indispensable part of modern vehicles, providing not only entertainment and information functions, but also gradually becoming a key component to enhance driving safety and comfort. In recent years, light - field display technology has attracted much attention because it can provide realistic three - dimensional images and reduce visual fatigue caused by long - term viewing. Especially in high - end vehicles, the application of light - field screens is growing rapidly.

[0003] Most of the current light - field screens on the market adopt an embedded installation method. Once installed, the embedded light - field screen will occupy a fixed physical space, and thus cannot be adjusted in position or direction according to the user's needs, restricting its flexibility and scene adaptability during use. Moreover, due to its fixed posture, the viewing angle of the audience is limited, and thus the best viewing effect cannot be achieved. Therefore, the design method of the embedded light - field screen still cannot meet the user's requirements. Summary of the Utility Model

[0004] Aiming at the above - mentioned deficiencies of the prior art, the technical problem to be solved by the utility model is to propose a hinge - flip type vehicle - mounted light - field display.

[0005] The technical solution adopted by the utility model to solve its technical problem is to propose a hinge - flip type vehicle - mounted light - field display for installation on a central panel with a receiving cavity, including: a light - field screen assembly rotatably arranged in the receiving cavity, the light - field screen assembly having a light - field screen that can be switched between an initial position and a maximum deployment position on the central panel;

[0006] A driving assembly detachably connected to the outer wall of the central panel, the driving end of the driving assembly being movably engaged with the light - field screen to drive the light - field screen to rotate relative to the central panel;

[0007] When the light - field screen is in the initial position, the upper end surface of the light - field screen is flush with the opening end of the receiving cavity, so that the screen of the light - field screen can be retracted into the receiving cavity;

[0008] When the driving assembly drives the light - field screen to switch from the initial position to the maximum deployment position, the light - field screen rotates relative to the central panel around its position close to the opening end of the receiving cavity, so that the light - field screen can flip and extend outside the receiving cavity to place the screen of the light - field screen vertically.

[0009] In the above-mentioned hinge-flipping vehicle-mounted light field display, a rotating shaft is provided on the side of the light field screen away from its screen. The rotating shaft is close to the open end of the accommodating cavity, and the end of the rotating shaft passes through the central panel and is connected to the driving end of the driving assembly.

[0010] In the above-mentioned hinge-flipping vehicle-mounted light field display, the light field screen assembly further includes an arc-shaped protection plate connected to the bottom wall of the light field screen. The arc-shaped protection plate can cover the open end of the accommodating cavity when the light field screen is in the initial position, so that the surface of the arc-shaped protection plate is flush with the surface of the central panel.

[0011] In the above-mentioned hinge-flipping vehicle-mounted light field display, the driving assembly includes:

[0012] A driving member is provided on the outer wall of the central panel, and a driving rod is coaxially connected to the driving end of the driving member;

[0013] A worm gear, a transmission bevel gear is provided at the end of the rotating shaft extending out of the central panel. Both the driving rod and the transmission bevel gear are movably engaged with the worm gear, so that when the driving member is driven, the light field screen can be driven to switch between the initial position and the maximum unfolded position through the rotating shaft.

[0014] In the above-mentioned hinge-flipping vehicle-mounted light field display, a housing is detachably connected to the outer wall of the central panel. An installation cavity is formed in the housing, and the transmission bevel gear, the driving member, the worm gear and the driving rod are all rotatably arranged in the installation cavity.

[0015] In the above-mentioned hinge-flipping vehicle-mounted light field display, the range of rotation of the light field screen relative to the central panel is 0° - 166°.

[0016] In the above-mentioned hinge-flipping vehicle-mounted light field display, a first limiting groove and a second limiting groove are further formed in the installation cavity. A bearing is arranged in the first limiting groove, and a limiting clamping plate is detachably connected in the second limiting groove. One end of the driving rod is movably clamped by the limiting clamping plate, and the other end is connected to the inner ring of the bearing.

[0017] In the above-mentioned hinge-flipping vehicle-mounted light field display, the housing is composed of an upper cover and a lower cover. The upper cover and the lower cover jointly form the installation cavity, and a plurality of extending parts are formed at the peripheries of the upper cover and the lower cover. A connecting hole is arranged on each extending part, and a plurality of mounting seats are arranged on the central panel. The connecting hole can be penetrated by a fixing part and connected in the mounting seat.

[0018] In the above-mentioned hinge - flip type vehicle - mounted light - field display, heat - dissipation holes and sound - amplifying holes are respectively arranged on the top wall and the bottom wall of the light - field screen.

[0019] In the above - mentioned hinge - flip type vehicle - mounted light - field display, a control switch is detachably installed on the central panel, and the control switch is electrically connected to the driving member.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] (1) By switching between the initial position and the maximum deployment position, the hinge - flip type vehicle - mounted light - field display of the utility model realizes the flipping action of the light - field screen. It can not only hide the light - field screen when not in use by the user, effectively saving the space occupied in the vehicle, but also can be freely adjusted in position and screen orientation according to the usage requirements of customers, effectively meeting the usage requirements of different users, and then achieving the best viewing effect, greatly improving the flexibility and scene adaptability of the light - field screen during use.

[0022] (2) The arc - shaped protective plate can cover the opening end of the accommodation cavity when the light - field screen is in the initial position, making the surface of the arc - shaped protective plate flush with the surface of the central panel. While ensuring the overall aesthetics of the vehicle interior, it can also provide a good protection effect for the light - field screen, avoiding damage to the light - field screen caused by external object collision.

[0023] (3) By arranging bearings in the housing, the smoothness and stability of the driving member to drive the rotation of the light - field screen through the output of the driving rod, worm gear, and transmission bevel gear are effectively improved, avoiding jamming during the rotation process and affecting the user experience of customers. At the same time, using the self - locking property of the driving rod and the worm gear provides guarantee for the stability of the light - field screen at the required viewing angle.

[0031] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0032] As Figure 1 shown, in this solution, a hinge-rotating in-vehicle light field display for automobiles is mainly described in detail. However, this hinge-rotating in-vehicle light field display is not limited to being used in automobiles and can also be applied to other places, such as the seats of high-speed trains or the ceilings of carriages.

[0033] As Figures 1 to 4 shown, a hinge-rotating in-vehicle light field display of the present invention is used to be installed on the central panel 1 having an accommodation cavity 10. Among them, the in-vehicle light field display includes: a light field screen assembly 2 rotatably arranged in the accommodation cavity 10, and the light field screen assembly 2 has a light field screen 20 that can be switched between the initial position and the maximum deployment position of the central panel 1; a driving assembly 3 detachably connected to the outer wall of the central panel 1, and the driving end of the driving assembly 3 is movably engaged with the light field screen 20 to drive the light field screen 20 to rotate relative to the central panel 1; when the light field screen 20 is in the initial position, the upper end surface of the light field screen 20 is flush with the opening end of the accommodation cavity 10, so that the screen of the light field screen 20 can be retracted into the accommodation cavity 10; when the driving assembly 3 drives the light field screen 20 to switch from the initial position to the maximum deployment position, the light field screen 20 rotates relative to the central panel 1 around its position close to the opening end of the accommodation cavity 10, so that the light field screen 20 can be flipped and extended out of the accommodation cavity 10 to place the screen of the light field screen 20 in the vertical direction.

[0034] This solution mainly realizes the flip-type design of the light field screen 20. It should be noted that this in-vehicle light field display is mainly installed on the central panel 1 in the front row of the co-pilot of the car. Specifically, when the user does not use the light field screen 20, the light field screen 20 is in Figure 1In the initial position shown, the light field screen 20 is contracted into the accommodation cavity 10 at this time, and the screen of the light field screen 20 faces the inner wall of the accommodation cavity 10, thereby achieving the effect of screen protection. At the same time, in this state, the light field screen 20 can be well hidden when the user does not use it, effectively saving the space occupied in the vehicle. When the user needs to watch a movie, the driving component 3 can drive the light field screen 20 that is movably engaged with it to rotate relative to the central panel 1 after being turned on to Figure 2 the maximum deployment position shown. At this time, most of the light field screen 20 extends out of the accommodation cavity 10 and is in a vertically placed posture to ensure that the user can reach the required viewing angle in the sitting posture. It can be seen that the flip-type light field screen 20 in this solution has a relatively simple overall structure compared with the embedded light field screen 20 structure. By switching between the initial position and the maximum deployment position, the flipping action of the light field screen 20 is realized. It can not only hide the light field screen 20 when the user does not use it, effectively saving the space occupied in the vehicle, but also can be freely adjusted in position and screen orientation according to the user's usage needs, so as to meet the best viewing effect for different users when using, greatly improving the flexibility and scene adaptability of the light field screen 20 when in use.

[0035] It should be noted that the light field screen 20 adopts a combination of optical elements and ultra-high resolution LCDs. It is mainly composed of an LCD display screen and microlenses. Among them, the microlenses are hemispherical fine products installed in front of the display screen. Through the action of the microlenses, the high-pixel display content is divided into multiple tiny viewing angles, and the specific number of these viewing angles depends on the size and layout of the microlenses. Such division helps to render three-dimensional stereoscopic images. It is also because of the use of the light field screen 20 that the glare phenomenon is effectively avoided during the passenger's ride and viewing process. While improving the picture quality, the long-distance imaging of the light field screen 20 can be used to greatly reduce visual fatigue.

[0036] A rotating shaft 21 is provided on the side of the light field screen 20 away from its screen. The rotating shaft 21 is close to the opening end of the accommodation cavity 10, and the end of the rotating shaft 21 passes through the central panel 1 and is connected to the driving end of the driving component 3.

[0037] As Figures 2 to 4 shown, in this embodiment, when the driving component 3 drives the rotating shaft 21 to rotate, the light field screen 20 can be driven by the rotating shaft 21 to Figure 1 the initial position shown to be flipped to Figure 2At the maximum deployment position shown, it is precisely because the rotating shaft 21 on the light field screen 20 is connected to the opening end of the central panel 1 near the accommodation cavity 10 that during the flipping process of the light field screen 20 around the axis of the rotating shaft 21, the screen of the light field screen 20 can be fully extended outside the accommodation cavity 10, ensuring that users are not affected by the central panel 1 during the movie-watching process and effectively guaranteeing the user's movie-watching experience.

[0038] Preferably, as Figure 1 With Figure 3 Shown, the light field screen assembly 2 in this solution further includes an arc-shaped protective plate 22 connected to the bottom wall of the light field screen 20. When the light field screen 20 is in Figure 1 the initial position, at this time the arc-shaped protective plate 22 covers the opening end of the accommodation cavity 10, making the surface of the arc-shaped protective plate 22 flush with the surface of the central panel 1. While ensuring the overall aesthetics of the central panel 1 in the vehicle, it can also provide good protection for the light field screen 20, preventing damage to the light field screen 20 caused by external object collisions. During the process of the light field screen 20 flipping to the maximum deployment position, the arc-shaped protective plate 22 is located between the accommodation cavity 10 and the light field screen 20. That is to say, the arc-shaped protective plate 22 can also guide and protect the flipping movement of the light field screen 20, preventing the light field screen 20 from colliding with the inner wall of the accommodation cavity 10 during the flipping process and causing damage or even inability to be used normally.

[0039] The driving assembly 3 includes: a driving member 30 arranged on the outer wall of the central panel 1, and a driving rod 31 coaxially connected to the driving end of the driving member 30; a worm gear 32, a transmission bevel gear 210 is arranged at the end of the rotating shaft 21 extending out of the central panel 1, and both the driving rod 31 and the transmission bevel gear 210 are movably engaged with the worm gear 32, so that when the driving member 30 is driven, the light field screen 20 can be driven to switch between the initial position and the maximum deployment position through the rotating shaft 21.

[0040] As Figure 4 Shown, when the driving member 30 is turned on, the driving rod 31 coaxially connected to its driving end can be driven to rotate. It should be noted that the driving rod 31 in this solution is a worm. Therefore, under the transmission cooperation of the worm and the worm gear 32, the rotating shaft 21 can be driven to rotate through the transmission bevel gear 210, thereby realizing the free switching of the light field screen 20 between the initial position and the maximum deployment position. The overall driving structure is relatively simple and can increase the torque when driving the light field screen 20 to flip under multi-stage transmission, ensuring the smoothness and stability of the light field screen 20 during the flipping process. Moreover, this solution can also utilize the self-locking characteristic of the worm and the worm gear 32 to ensure the stability of the light field screen 20 at the viewing angle required by the user, thereby ensuring that the user's movie-watching experience is not affected.

[0041] Further, in this solution, regarding the rotation of the light field screen 20, it can be achieved by the rotation angle of the rotating shaft 21 driven when the driving member 30 is turned on, so that the light field screen 20 can be freely switched between any angles between the initial position (i.e., Figure 1 the state shown) and the maximum unfolded position (i.e., Figure 2 the state shown). Preferably, in this solution, the range of rotation of the light field screen 20 relative to the central panel 1 is 0° to 166°, so as to meet different viewing angles required by users, effectively improving the convenience of adjusting the viewing angle of the light field screen 20 and the viewing experience.

[0042] Preferably, a housing 11 is detachably connected to the outer wall of the central panel 1. An installation cavity 110 is formed inside the housing 11. The transmission bevel gear 210, the driving member 30, the worm gear 32, and the driving rod 31 are all rotatably arranged in the installation cavity 110. Through the design of the housing 11 on the outer wall of the central panel 1, it can not only provide convenience for the installation of each component in the above driving assembly 3, effectively improving the assembly efficiency of this structure, but also play a certain protective effect on each component, preventing external dust or impurities from entering and affecting the service life of the components.

[0043] A first limiting groove 110a and a second limiting groove 110b are further formed in the installation cavity 110. A bearing 110c is arranged in the first limiting groove 110a, and a limiting card plate 110d is detachably connected in the second limiting groove 110b. One end of the driving rod 31 is movably clamped by the limiting card plate 110d, and the other end is connected to the inner ring of the bearing 110c.

[0044] As Figure 4 shown, the first limiting groove 110a in this solution is mainly used for the installation of the bearing 110c, while the first limiting groove 110a is used to connect the limiting card plate 110d. During the installation process of the above driving rod 31, the bearing 110c at the end of the driving rod 31 can be used in cooperation with the first limiting groove 110a, and the other end relies on the cooperation of the limiting card plate 110d and the second limiting groove 110b, thereby ensuring the stability of the driving rod 31 during rotation, achieving the effect that the driving rod 31 and the driving end of the driving member 30 are coaxially arranged and rotate synchronously, greatly improving the stability of this structure during operation.

[0045] Preferably, as Figure 4As shown in the figure, a through hole 13 is provided on the central panel 1, and the end of the rotating shaft 21 can pass through the through hole 13, so as to realize the synchronous rotation of the worm gear 32 driving the transmission helical gear 210 and the rotating shaft 21. Preferably, in this solution, the same bearings 110c are also provided in both the through hole 13 and the housing 11. The inner ring of the bearing 110c is connected to the rotating shaft 21, thereby ensuring the smoothness of the rotating shaft 21 during rotation, and providing guarantee for the smoothness and stability when the rotating shaft 21 drives the light field screen 20 to freely switch between the initial position and the maximum deployment position.

[0046] The housing 11 is composed of an upper cover 111 and a lower cover 112. The upper cover 111 and the lower cover 112 jointly form an installation cavity 110, and a plurality of extension parts 113 are formed at the peripheries of the upper cover 111 and the lower cover 112. Each extension part 113 is provided with a connection hole 113a. A plurality of mounting seats 12 are provided on the central panel 1, and the connection hole 113a can be penetrated by a fixing member and connected in the mounting seat 12.

[0047] As Figures 1 to 4 shown in the figure, the housing 11 is installed by the upper cover 111 and the lower cover 112. Among them, when the connection hole 113a on the extension part 113 of the upper cover 111 or the lower cover 112 is aligned with the mounting seat 12, the worker can pass the fixing member through the connection hole 113a and connect it in the mounting seat 12, thereby realizing the installation between the housing 11 and the central panel 1. It should be noted that the fixing member in this solution can be replaced by other fixing members such as screws. The overall structure of this connection method is simple, convenient for installation and disassembly, and also provides convenience for subsequent maintenance and replacement.

[0048] Preferably, in this embodiment, as Figure 3 shown in the figure, heat dissipation holes 200 and sound amplification holes 201 are respectively provided on the top wall and the bottom wall of the light field screen 20. When the light field screen 20 is switched to Figure 2 the maximum deployment position shown in the figure, at this time, the sound emitted from the light field screen 20 can be externally emitted through the sound amplification hole 201 to meet the required viewing effect of the user. Similarly, during the use of the light field screen 20, through the heat dissipation hole 200, it can effectively prevent the light bulb (not shown in the figure) in the light field screen 20 from being affected by overheating and affecting normal use. It should be noted that when the user does not use the light field screen 20 (that is, when the light field screen 20 is in Figure 1 the state shown in the figure), both the heat dissipation hole 200 and the sound amplification hole 201 are in the accommodation cavity 10, effectively preventing external impurities or foreign objects from entering the light field screen 20 and shortening its service life.

[0049] Furthermore, preferably, as Figure 1As shown in the figure, a control switch 14 is detachably installed on the central panel 1. By electrically connecting the control switch 14 to the driving member 30, when the user needs to use the light field screen 20, the user can control the turning on and off of the driving member 30 through the control switch 14, and then adjust the light field screen 20 to the viewing angle required by the user. The operation is simple, which brings great convenience to the customer when watching movies.

[0050] It should be noted that the driving member 30 in this solution can be replaced by other driving devices such as servo motors and stepper motors. Through the motor hinge axle pin (not shown in the figure), the effects of shock absorption, buffering, and transmission precision compensation can be achieved. In addition, the detachable installation referred to in this solution can adopt conventional connection methods such as bolts and screws.

[0051] It should be noted that all directional indicators (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indicators will also change accordingly.

[0052] In addition, in the present invention, descriptions such as "first", "second", and "one" are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0053] In the present invention, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the internal connection of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] In addition, the technical solutions between various embodiments of the present invention can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
