[0002] With the increasingly diversified application scenarios of electronic devices, users' demands for the adjustment functions of display devices are becoming more complex and refined. Traditional display device support adjustment devices mostly adopt a single-direction adjustment or a structure design with limited degrees of freedom, which makes it difficult to simultaneously meet users' diverse needs for the position and angle of the display device in different usage scenarios.

[0003] Currently, common display device adjustment devices on the market have many limitations. For example, some screen stands only have a single forward and backward extension function, and users cannot adjust the left and right direction of the screen according to the actual viewing angle requirements, making it difficult to achieve the best viewing angle in scenarios such as multiple people watching or multiple devices operating together; other screen adjustment devices, although they have a certain rotation function, require users to manually disassemble and reinstall the screen components when adjusting the forward and backward position, which is cumbersome and easy to damage the device, greatly reducing the convenience and efficiency of use.

[0033] The present invention will now be described based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail, but well-known methods, processes, procedures, and elements are not described in detail in order to avoid obscuring the essence of the present invention.

[0034] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[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 utility model, 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 utility model, unless otherwise stated, "a plurality of" means two or more.

[0037] The telescopic tilting device provided by this utility model can be applied to various scenarios, including transportation and commercial facilities, consumer electronics and smart homes, offices and education, and industry. For example, in transportation and commercial facilities, it can be used in in-vehicle central control screens, rear-seat entertainment screens, or shopping guide screens. In consumer electronics and smart home scenarios, it can be used in smart TVs or smart home central control devices. In offices and education scenarios, it can be used in smart conference equipment or blackboard screens. In industrial scenarios, it can be used in factory control consoles or the cockpits of ships and spacecraft. The telescopic tilting device is particularly useful in space-constrained environments, allowing for horizontal telescopic extension and retraction, and left and right tilting of screen components.

[0038] The telescopic swing device provided by this utility model will be described in detail below with reference to the accompanying drawings.

[0039] like Figure 1 As shown, the telescopic and swaying device provided by this utility model is used to extend and retract the screen assembly horizontally and sway it left and right. It includes a first push-pull assembly 1, a second push-pull assembly 2, and a mounting base 3.

[0040] The first push-pull assembly 1 includes a first fixed member and a first movable member. The first fixed member is fixedly mounted on the mounting base 3, and the first movable member is movably mounted relative to the first fixed member. The first movable member is rotatably connected to the screen assembly through a first hinge shaft 4. The axis of the first hinge shaft 4 is perpendicular to the direction of movement of the first movable member.

[0041] The second push-pull assembly 2 includes a second fixed member and a second movable member. The second fixed member is fixedly mounted on the mounting base 3, and the second movable member is movably mounted relative to the second fixed member. The second movable member is rotatably connected to the screen assembly via a second hinge shaft 5. The axis of the second hinge shaft 5 is perpendicular to the direction of movement of the second movable member.

[0042] The direction of movement of the first movable component is parallel to the direction of movement of the second movable component;

[0043] The axis of the first hinge axis 4 and the axis of the second hinge axis 5 are parallel to each other.

[0044] It should be noted that the horizontal forward and backward extension described in this utility model refers to moving away from or towards the mounting base 3 along the direction of movement of the movable part in the horizontal direction; the horizontal left and right sway refers to one side of the screen assembly swinging towards the mounting base 3 and the other side swinging away from the mounting base 3 in the direction perpendicular to the direction of movement of the movable part in the horizontal direction, or one side of the screen assembly swinging away from the mounting base 3 and the other side swinging towards the mounting base 3.

[0045] The telescopic and tilting device provided by this utility model, through the coordinated design of the first push-pull component 1 and the second push-pull component 2, enables the connected screen component to simultaneously have forward and backward telescopic and left and right tilting functions. When multiple people are viewing the screen together, users do not need to perform any additional operations; they can quickly adjust the position and angle of the screen component simply by controlling the two push-pull components, ensuring that each viewer gets the best viewing angle. In multi-device collaborative operation scenarios, the orientation of the screen component can be flexibly adjusted, making it easier for users to handle content from different devices simultaneously, thereby significantly improving efficiency and user experience.

[0046] In the telescopic tilting device provided by this utility model, the fixed part is fixedly set on the mounting base 3, and the movable part is movably set relative to the fixed part. The movable part is rotatably connected to the screen assembly through the hinge shaft, and the axis of the hinge shaft is perpendicular to the movement direction of the movable part. The position and angle of the screen assembly can be adjusted by simple push-pull and rotation operations without complicated disassembly and assembly steps, which reduces the user's operation difficulty and the risk of equipment damage, and greatly improves the convenience and efficiency of use.

[0047] The telescopic and swaying device provided by this utility model integrates forward and backward telescopic and left and right swaying functions, optimizing the structural design and space utilization. This facilitates the miniaturization and integration of display devices, adapting them to more application scenarios. Furthermore, the two push-pull components, arranged parallel to each other in the direction of movement of the moving parts, provide stable and balanced power output. While enabling flexible adjustment of the screen components, this ensures that the screen components remain stable in any position, avoiding problems such as shaking or displacement.

[0048] In some embodiments, in the first push-pull assembly 1 and the second push-pull assembly 2, at least one of the fixed members is a strip slide rail, the movable member is a sliding member, and the sliding member slides in conjunction with the slide rail.

[0049] Specifically, such as Figure 1 As shown, in the first push-pull assembly 1, the first fixed member adopts the first slide rail 11, the first movable member adopts the first sliding member 12, the first slide rail 11 is fixedly set on the mounting base 3, the first sliding member 12 is slidably set on the first slide rail 11, and the first sliding member 12 is rotatably connected to the screen assembly through the first hinge shaft 4.

[0050] In the second push-pull assembly 2, the second fixed member adopts the second slide rail 21, the second movable member adopts the second sliding member 22, the second slide rail 21 is fixedly set on the mounting base 3, the second sliding member 22 is slidably set on the second slide rail 21, and the second sliding member 22 is rotatably connected to the screen assembly through the second hinge shaft 5.

[0051] The first slide rail 11 and the second slide rail 21 are arranged in parallel. Both the first slide rail 11 and the second slide rail 21 can be strip slide rails.

[0052] The telescopic tilting device provided by this utility model enables the screen assembly to tilt simultaneously with its extension and retraction, rather than requiring it to extend first before tilting. This allows for flexible front-to-back extension and left-to-right tilting in a single operation. Of course, when tilting is not required, the telescopic tilting device can also achieve only extension and retraction. That is, by sliding the first slider 12 and the second slider 22 different distances, the screen assembly can tilt simultaneously with its extension and retraction. By sliding the first slider 12 and the second slider 22 in the same direction the same distance, the screen assembly can achieve only extension and retraction, increasing the overall practicality of the device and allowing users to operate it flexibly according to their needs. This improves the space utilization and ease of operation around the telescopic tilting device.

[0053] In the above embodiments, in the first push-pull assembly 1 and the second push-pull assembly 2, the one that provides the strip slide rail and the sliding member also includes a transmission rod, one end of which is connected to the sliding member and the other end is rotatably connected to the screen assembly 6.

[0054] Specifically, such as Figure 1 As shown, the first push-pull assembly 1 may further include a first transmission rod 13. The extension direction of the first transmission rod 13 is consistent with the sliding direction of the first sliding member 12. One end of the first transmission rod 13 is fixedly connected to the first sliding member 12, and the other end is rotatably connected to the screen assembly 6 through the first hinge shaft 4.

[0055] The second push-pull assembly 2 may also include a second transmission rod 23. The extension direction of the second transmission rod 23 is consistent with the sliding direction of the second sliding member 22. One end of the second transmission rod 23 is fixedly connected to the second sliding member 22, and the other end is rotatably connected to the screen assembly 6 through the second hinge shaft 5.

[0056] When the slider slides on the slide rail, the transmission rod can efficiently transmit linear motion to the screen assembly 6, driving it to extend and retract back and forth; at the same time, the transmission rod is hinged to the screen assembly 6 through the hinge shaft, giving the screen assembly 6 rotational freedom. When the two sets of transmission rods move asynchronously, the screen assembly 6 can swing left and right.

[0057] In one specific embodiment, the transmission rod is a telescopic sleeve rod, which includes a sleeve portion and a telescopic rod. The sleeve portion is fixedly connected to the sliding member, and the telescopic rod portion is slidably inserted into the sleeve portion. The end of the telescopic rod extending out of the sleeve portion is rotatably connected to the screen assembly 6.

[0058] The transmission rod employs a telescopic sleeve structure, allowing its length to automatically adjust as the sliding member moves along the slide rail. This means that when the sliding member drives the sleeve to slide back and forth, the telescopic rod can extend or retract within the sleeve, avoiding motion interference caused by the fixed length of traditional rigid transmission rods and ensuring smooth transmission during screen extension and retraction. Simultaneously, the end of the telescopic rod extending beyond the sleeve is rotatably connected to the screen assembly 6 (e.g., hinged). In addition to allowing the screen assembly 6 to move back and forth, the asynchronous extension and retraction of the two sets of telescopic sleeves provides the screen assembly 6 with a degree of rotational freedom for left and right yaw (e.g., when one set of telescopic sleeves extends and the other shortens, the screen assembly 6 can rotate around the hinge point).

[0059] Furthermore, by adjusting the depth of the telescopic rod inserted into the sleeve, it can flexibly adapt to different installation spaces and the adjustment range of screen component 6, improving the versatility of the telescopic tilting device. The nested structure of the sleeve and the telescopic rod also reduces the space occupied by the transmission rod, making the overall device more compact.

[0060] In another specific embodiment, the transmission rod is a stepped rod, including a first large section 131, a small section 132 and a second large section 133 connected in sequence. The ends of the first large section 131 and the second large section 133 away from the small section 132 are plate-shaped structures, which are perpendicular to the first hinge axis 4. The first large section 131 and the second large section 133 are fixedly connected to the sliding member and rotatably connected to the screen assembly 6 through their respective plate-shaped structures.

[0061] The transmission rod adopts a stepped rod structure, which can reduce the load on the sliding parts, ensure the strength of the transmission rod, and increase the reliability of the connection with the sliding parts and screen assembly 6. In particular, the plate-like structure design can also facilitate the rotational connection with screen assembly 6.

[0062] In the above embodiments, such as Figure 2 As shown, the first large segment 131, the small segment 132, and the second large segment 133 can be separate structures. Each of the first large segment 131 and the second large segment 133 has a mounting hole near the end of the small segment 132. The two ends of the small segment 132 are respectively inserted into the mounting holes of the first large segment 131 and the second large segment 133. The small segment 132 can be detachably connected to the first large segment 131 and the second large segment 133 via a threaded connection, or it can be fixedly connected via an interference fit.

[0063] In some embodiments, in the first push-pull assembly 1 and the second push-pull assembly 2, at least one of the fixed members is an outer sleeve and the movable member is an inner sleeve, with the inner sleeve being movably inserted into the outer sleeve.

[0064] Specifically, in the first push-pull assembly 1, the first fixed member adopts a first outer sleeve, the first movable member adopts a first inner sleeve, the first inner sleeve is slidably disposed on the first outer sleeve, and the first inner sleeve is rotatably connected to the screen assembly 6 through the first hinge shaft 4.

[0065] In the second push-pull assembly 2, the second fixed member adopts the second outer sleeve, the second movable member adopts the second inner sleeve, the second outer sleeve is fixedly installed on the mounting base 3, and the second inner sleeve is rotatably connected to the screen assembly 6 through the second hinge shaft 5.

[0066] The first outer tube and the second outer tube are arranged in parallel.

[0067] The push-pull assembly, through its inner and outer tubing insert design, not only ensures the stability and guidance of the push-pull action, reducing swaying and offset during movement, but also enables telescopic functionality within a limited space, saving equipment space. Simultaneously, the rotating connection of the hinge axis allows the screen assembly 6 to adjust its angle around the hinge axis, meeting the user's needs from different viewing angles. This combined structure ensures both the strength and reliability of the push-pull assembly, while also giving the screen assembly 6 a high degree of movement flexibility, enhancing the device's practicality and user experience.

[0068] In some embodiments, such as Figure 3 As shown, the telescopic tilting device also includes a support assembly 7, which is disposed between the first push-pull assembly 1 and the second push-pull assembly 2. The support assembly 7 includes a third fixed member and a third movable member. The third fixed member is fixedly disposed on the mounting base 3, and the third movable member is movably disposed relative to the third fixed member and is rotatably connected to the screen assembly 6 through the third hinge shaft 8. The direction of movement of the third movable member is parallel to the direction of movement of the first movable member. The axis of the third hinge shaft 8 is perpendicular to the direction of movement of the third movable member.

[0069] Specifically, the third fixed component can be a slide rail, and the third movable component can be a slide block. The slide rail is fixedly installed on the mounting base 3, and the slide block is slidably installed on the slide rail. The slide block is rotatably connected to the screen assembly 6 through the third hinge shaft 8.

[0070] In addition, the support assembly 7 may also include a support plate, the extension direction of which is parallel to the sliding direction of the slide, one end of which is fixedly connected to the slide, and the other end of which is rotatably connected to the screen assembly 6 via a third hinge shaft 8.

[0071] By adding a support component 7 between the two sets of push-pull components, and hinge the third movable part in the support component 7 to the screen component 6 through the third hinge axis 8, a more stable and reliable motion and fixation guarantee can be provided for the screen component 6, significantly improving the stability and structural strength of the screen component 6 during the motion process.

[0072] In some embodiments, such as Figure 3 As shown, the telescopic tilting device also includes a mounting plate 9. The mounting surface of the mounting plate 9 is used to mount the back of the screen assembly 6. A connecting lug is provided on the side of the mounting plate 9 away from the mounting surface. The first hinge shaft 4 and the second hinge shaft 5 are respectively provided on different connecting lugs. The first movable member and the second movable member are rotatably connected to the screen assembly 6 through the mounting plate 9.

[0073] Specifically, such as Figure 4 As shown, a first connecting lug 91 and a second connecting lug 92 are provided on the side of the mounting plate 9 away from the mounting surface. The first connecting lug 91 is rotatably connected to the first movable member through the first hinge shaft 4, and the second connecting lug 92 is rotatably connected to the second movable member through the second hinge shaft 5.

[0074] The mounting plate 9 also has a third connecting lug 93 protruding from the side opposite to the mounting surface. The third connecting lug 93 is located between the first connecting lug 91 and the second connecting lug 92. The third connecting lug 93 is rotatably connected to the third movable part in the support assembly 7 through the third hinge shaft 8.

[0075] Along the length of the screen, the hinge points of the first movable member and the first connecting lug 91, the second movable member and the second connecting lug 92, and the third movable member and the third connecting lug 93 can be located on the same straight line. Preferably, this straight line is parallel to the length of the screen. When the screen extends and retracts relative to the mounting base 3, the three-point support can distribute the screen's gravity and thrust, avoiding excessive force on a single point. When swaying left and right, the hinge point of the third movable member and the third connecting lug 93 serves as an intermediate fulcrum, forming a seesaw-like balance structure with the first and second movable members, which can suppress screen slippage.

[0076] The mounting plate 9 is also provided with positioning holes 94, which are used to achieve precise installation, fixation and positioning when the mounting plate 9 is connected to the back of the screen, so as to ensure the accuracy and stability of the installation process.

[0077] Specifically, along the length of the mounting plate 9, positioning holes 94 are provided on the side of the first connecting lug 91 away from the second connecting lug 92, and on the side of the second connecting lug 92 away from the first connecting lug 91.

[0078] The mounting plate 9 is also provided with a cable outlet hole 95 and a fixing hole 96. The connecting cable of the screen assembly 6 passes through the cable outlet hole 95 and connects to other external devices. The fixing hole 96 cooperates with the screw to connect the back of the screen assembly 6 to the mounting plate 9, so that the screen assembly 6 is fixed on the mounting plate 9.

[0079] In other embodiments, based on the telescopic swing device provided by this utility model, such as Figure 5 As shown, the present invention also provides a display device, which includes a screen assembly 6 and the above-mentioned telescopic tilting device, wherein the first movable member and the second movable member are respectively rotatably connected to the screen assembly 6.

[0080] In the display device provided by this utility model, the screen assembly 6, under the coordinated action of the first push-pull assembly 1 and the second push-pull assembly 2, can simultaneously have the functions of forward and backward extension and left and right tilting. Moreover, the screen can tilt flexibly without relying on the prior extension.

[0081] In other embodiments, based on the display device provided by this utility model, this utility model also provides an automotive dashboard, which includes an instrument frame and the aforementioned display device, wherein the display device is mounted on the instrument frame, and the screen component 6 in the display device is exposed outside the instrument frame.

[0082] By mounting the display device within the instrument cluster, the driver can adjust the distance between themselves and the display device based on their seating position or eye level, avoiding issues of excessively close or far viewing distance caused by fixed installation of the display. In navigation and entertainment scenarios, screen component 6 can tilt towards the driver's side, shortening the distance the driver's line of sight needs to travel; it can also tilt towards the passenger's side when the passenger needs to operate the device, improving ease of interaction. The tilting function also allows the display surface to avoid direct sunlight, reducing glare through physical adjustment.

[0083] The screen component 6 is exposed on the instrument frame and is retractable, eliminating the need for reserved depth space for fixed installation. This makes the instrument panel thinner and lighter, freeing up more layout space for internal components such as wiring harnesses and sensors.

[0084] Compared to traditional embedded screens, the exposed design of screen component 6 in this invention avoids the edges of screen component 6 being obscured by the frame, thereby maximizing the display area of ​​screen component 6. This invention elevates the traditional in-vehicle screen from a static information carrier to an intelligent terminal that can actively adapt to user needs, promoting the development of in-vehicle human-machine interaction towards a more natural and safer direction.

[0085] In other embodiments, the present invention also provides an automobile that includes the aforementioned automobile dashboard or display device.

[0086] Applying the aforementioned automotive dashboards or display devices to automobiles, through the synergy of mechanical structure and intelligent control, can achieve multi-dimensional technological breakthroughs. For example, by combining sensor data such as seat position and ambient light, the movement of motors or cylinders can be controlled to achieve seamless adaptive adjustment of screen component 6, significantly enhancing the accuracy of human-machine interaction and driving safety, and propelling automobiles towards intelligence and personalization.

[0087] Those skilled in the art will understand that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0088] It should be understood that the above-described embodiments are merely exemplary and not restrictive. Without departing from the basic principles of this utility model, any obvious or equivalent modifications or substitutions made by those skilled in the art regarding the above details will be included within the scope of the claims of this utility model.
