Description

Technical Field

[0001] This invention relates to the field of vehicle display technology, and in particular to a display screen angle adjustment device that reduces design limitations. Background Technology

[0002] In-vehicle displays are human-machine interfaces installed in cars, used to display a wide range of information such as vehicle status, navigation, and communication information, providing drivers with numerous conveniences. Currently, in-vehicle central control multimedia displays generally use a fixed angle. Due to the inherent limitations of the display's viewing angle, at side viewing angles, the screen colors typically become distorted, the display effect deteriorates, and the displayed content may even become illegible. This situation is even more pronounced in strong sunlight.

[0003] To address the aforementioned issues, patent application number 201621134128.8 discloses a mounting structure for a rotatable and flip-up vehicle display screen, comprising: an instrument panel body having a receiving groove; a first rotating shaft located within the receiving groove, movably coupled to the instrument panel body, the first rotating shaft being arranged in a lateral direction; a second rotating shaft movably coupled to the first rotating shaft, the axis of the second rotating shaft being perpendicular to the axis of the first rotating shaft; and a display screen body located within the receiving groove, the display screen body being fixedly coupled to the second rotating shaft. As can be seen from the above prior art, existing automotive display screen adjustment mechanisms, through the movable design of the display screen body, allow the driver to easily adjust the display screen body to a suitable position at any time, making operation of the display screen body more convenient. However, the screen angle adjustment device in the aforementioned patent requires a large amount of space, necessitating that the surrounding design avoids the screen's movement envelope or exposes the mechanism, thus imposing certain limitations on the design. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is how to provide a display screen angle adjustment device that requires less space and reduces design limitations.

[0005] To address the aforementioned technical problems, the present invention provides a display screen angle adjustment device that reduces design limitations, comprising:

[0006] A telescopic assembly, comprising a first support component and a second support component, wherein the second support component is telescopically connected to the first support component;

[0007] The display assembly includes a third support component and a display screen. The third support component is fixedly connected to the back of the display screen and rotatably connected to a second support component. The extension and retraction direction of the second support component is not parallel to the rotation axis of the third support component. The front of the display screen is a screen for displaying text, images, and videos.

[0008] In the first working state, the non-obtuse angle formed by the screen of the display and the extension direction of the second bracket component is α1, and the length of the second bracket component extending beyond the first bracket component is L1.

[0009] In the second working state, the non-obtuse angle formed by the screen of the display and the extension direction of the second bracket component is α2, and the length of the second bracket component extending beyond the first bracket component is L2.

[0010] Where α2<α1≤90, 0<L1<L2.

[0011] In one embodiment of the present invention, the rotation axis of the third support component is perpendicular to the extension and retraction direction of the second support component.

[0012] In one embodiment of the present invention, the rotation axis of the third support component is parallel to the screen height direction of the display screen.

[0013] In one embodiment of the present invention, the third support component is connected to the second support component via a damping hinge.

[0014] In one embodiment of the present invention, the second bracket component is connected to the first bracket component via a guide rail.

[0016] In one embodiment of the present invention, the first support component is further provided with a first limiting structure for limiting the length of the second support component extending out of the first support component and a second limiting structure for limiting the length of the second support component retracting into the first support component.

[0017] In one embodiment of the present invention, both the first support component and the second support component are strip plates, and the strip plates extend along the extension and retraction direction of the second support component.

[0018] In one embodiment of the invention, the third bracket component is detachably connected to the display screen.

[0019] In one embodiment of the present invention, the display screen is a vehicle central control screen, and the first bracket component is connected to the vehicle component.

[0020] The technical solution of the present invention has the following advantages over the prior art:

[0021] 1) The display screen angle adjustment device for reducing design limitations according to the present invention includes a first support component, a second support component, and a third support component. The second support component is telescopically connected to the first support component, and the third support component is rotatably connected to the second support component. When there are obstacles around the display screen during angle adjustment, the second support component automatically extends while the display screen is rotated, allowing the display screen to overcome the obstacles and continue rotating to the required angle.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0029] Example 1

[0030] See Figure 1 As shown in the illustration, a display screen angle adjustment device that reduces design limitations includes:

[0031] The telescopic assembly includes a first support component 1 and a second support component 2, wherein the second support component 2 is telescopically connected to the first support component 1.

[0032] The display component includes a third bracket component 3 and a display screen 4. The third bracket component 3 is fixedly connected to the back of the display screen 4. The third bracket component 3 is rotatably connected to the second bracket component 2. The extension and retraction direction of the second bracket component 2 is not parallel to the rotation axis of the third bracket component 3. The front of the display screen 4 is a screen for displaying text, images and videos.

[0033] In the first working state, the non-obtuse angle formed by the screen of the above-mentioned display screen 4 and the extension direction of the above-mentioned second bracket component 3 is α1, and the length of the above-mentioned second bracket component 3 extending out of the above-mentioned first bracket component 1 is L1.

[0034] In the second working state, the non-obtuse angle formed by the screen of the above-mentioned display screen 4 and the extension direction of the above-mentioned second bracket component 2 is α2, and the length of the above-mentioned second bracket component 2 extending out of the above-mentioned first bracket component 1 is L2.

[0035] Where α2<α1≤90, 0<L1<L2.

[0036] Based on the relationship between the included angle and the extension length in the first and second working states, it can be seen that when the non-obtuse angle formed by the screen and the extension direction of the second support component is large, the extension length of the second support component beyond the first support component is small; conversely, when the non-obtuse angle formed by the screen and the extension direction of the second support component is small, the extension length of the second support component beyond the first support component is large. This invention connects the second support component to the first support component in a telescopic manner, and the third support component is rotatably connected to the second support component. When there are obstacles around the screen during angle adjustment, the second support component automatically extends while the screen is rotating, allowing the screen to overcome the obstacles and continue rotating to the desired angle. This invention achieves large-angle screen adjustment even in situations with limited space and the need to maintain the integrity of the surrounding design, overcoming the disadvantages of limited space and layout that prevent the installation of mechanisms, and fully utilizing the advantages of the design. When adjusting the screen angle, the second telescopic component automatically extends, making screen angle adjustment simple and convenient. The overall screen angle adjustment device is stable, reliable, and cost-effective. In actual use, the display screen is manually rotated around its axis of rotation. When the screen encounters an obstacle during rotation, the screen is continued to bend, at which point the second support component extends beyond the first support component, and the screen moves to its front side, allowing it to continue rotating around the obstacle. This greatly improves space utilization. Specifically, in this embodiment, to more clearly describe the working principle of the invention, the extension / retraction direction of the second support component is set to the front-back direction, meaning the second support component is extendable / retractable to the first support component in the front-back direction. The rotation axis of the third support component is set to the vertical direction, meaning the third support component is rotatable / rotatable to the second support component in the up-down direction. Therefore, the display screen can translate in the front-back direction and also swing left and right. The left side of the display screen has a left contact point 41, and the right side of the display screen has a right contact point 42. The first support component is then fixedly installed. When the display screen is bent and rotated to its left limit from its initial state, the left contact point 41 of the display screen will first contact the surrounding IP structure. After contact, if the display screen is bent to the left again, the force is transmitted to the second support component. The second support component will extend from the first support component, and the display screen will move towards the front side of the display screen along with the second support component. The display screen can continue to rotate to the left, reaching the angle required for left rotation. When the display screen is bent and rotated to its right limit from its initial state, the right contact point 42 of the display screen will first contact the surrounding IP structure. After contact, if the display screen is bent to the right again, the force is transmitted to the second support component. The second support component will extend from the first support component, and the display screen will move towards the front side of the display screen along with the second support component. The display screen can continue to rotate to the right, reaching the angle required for right rotation.

[0037] In this preferred embodiment, the rotation axis of the third support component 3 is perpendicular to the extension / retraction direction of the second support component 2. When the extension / retraction direction of the second support component is forward / backward, the rotation axis of the third support component lies in a vertical plane. This rotation axis may extend horizontally, vertically, or omnidirectionally. For example, when the rotation axis extends horizontally, the display screen can flip upwards and downwards by a certain angle; when it extends vertically, the display screen can flip to the left and right by a certain angle; and when it extends omnidirectionally, the display screen can flip in any direction by a certain angle. In this case, the third support component is connected to the second support component via a spherical connection structure. The rotation axis is primarily set according to the desired flipping method of the display screen. Specifically, in this embodiment, the rotation axis extends vertically.

[0038] In this preferred embodiment, the rotation axis of the third support component 3 is parallel to the screen height direction of the display screen 4. Specifically, in this embodiment, the rotation axis of the third support component 3 is in the up-down direction. When the viewer is on the left, the display can be tilted to the left; when the viewer is on the right, the display can be tilted to the right. The display can be used from different positions.

[0039] In this preferred embodiment, the third support component 3 is connected to the second support component 2 via a damping hinge 5. A damping hinge, also known as a hydraulic hinge, is a type of hinge that uses a novel technology to adapt to the closing speed of the door. Even when the door is closed forcefully, it closes gently, ensuring perfect and quiet movement. Because the third support component is connected to the second support component via the damping hinge, the third support component rotates relatively smoothly. After rotating to a certain position, it will not easily turn back without external force, thus allowing the display screen to maintain the required angle.

[0040] In this preferred embodiment, the second support component 2 is connected to the first support component 1 via a guide rail 6. The guide rail, made of metal or other materials, is a groove or ridge that supports, fixes, and guides moving devices or equipment while reducing friction. The longitudinal grooves or ridges on the guide rail surface are used to guide and fix machine parts, specialized equipment, instruments, etc. Guide rails, also known as slide rails, linear guide rails, or linear slide rails, are used in linear reciprocating motion applications. They have a higher rated load than linear bearings and can withstand a certain amount of torque, enabling high-precision linear motion under high loads. The connection between the second support component and the first support component via the guide rail makes the extension and retraction of the second support component smoother and more precise.

[0041] In a preferred embodiment of this invention, the display screen angle adjustment device further includes an elastic reset component 7. The reset force of the elastic reset component 7 is in the same direction as the retraction direction of the second support component 2, and the reset force of the elastic reset component 7 is slightly greater than the retraction resistance of the second support component 2. By setting the elastic reset component, the second telescopic component can automatically retract when the display screen angle is adjusted, making the display screen angle adjustment simple and convenient. The overall display screen angle adjustment device is stable and reliable, and the cost is reduced. When the display is rotated from the leftmost or rightmost extreme position to the initial position, and the display screen is manually rotated to the right, the force of the elastic reset component will exceed the resistance of the second support component, causing the elastic reset component to drive the second support component to retract into the first support component. In normal operation, the display screen does not need to be rotated. At this time, the elastic reset force of the elastic reset component keeps the second support component in the retracted state, making the entire display screen angle adjustment device more compact.

[0042] In this preferred embodiment, the elastic reset component 7 is a constant force spring. A spring is a mechanical part that works by utilizing elasticity. A part made of elastic material deforms under the action of external force and returns to its original shape after the external force is removed. It is also called a "spring". It is generally made of spring steel. There are many types of springs. According to their shape, they mainly include helical springs, spiral springs, leaf springs, and irregular springs. The constant force spring in this embodiment can be a compression spring or a tension spring. A compression spring is a helical spring that bears axial compression. The material used is mostly circular in cross section, but it is also made of rectangular or multi-strand steel wire. The spring is generally of equal pitch. The shapes of compression springs include cylindrical, conical, convex, and concave, as well as a small number of non-circular shapes. There is a certain gap between the coils of a compression spring. When subjected to external load, the spring contracts and deforms, storing deformation energy. A tension spring (also called a tension spring, or simply a tension spring) is a helical spring that bears axial tension. Tension springs are generally made of circular cross section material. When not under load, the coils of a tension spring are generally tightly closed without gaps. Choose between tension springs or compression springs and spring connection methods according to actual needs.

[0043] In a preferred embodiment of this invention, the first support component 1 is further provided with a first limiting structure 11 for limiting the length of the second support component 2 extending out of the first support component 1 and a second limiting structure 12 for limiting the length of the second support component 2 retracting into the first support component 1.

[0044] Specifically, the first and second limiting structures are essentially stop structures used to restrict the range of movement of the second support component, i.e., to prevent the second support component from moving out of the set stroke and range. The first and second limiting structures are limiting blocks, limiting plates, or limiting posts. In this embodiment, both the first and second limiting structures are limiting posts, which are fixed to the first support component, with the upper end of the limiting post protruding from the first support component.

[0045] In this preferred embodiment, both the first support component 1 and the second support component 2 are strip plates, extending along the telescopic direction of the second support component 2. The first and second support components satisfy the requirements for telescopic movement and installation. Specifically, the second support component is movably connected above the first support component, one end of the second support component cannot extend beyond the first support component, while the other end extends beyond the first support component, serving as a relatively free end. The third support component is connected to the relatively free end of the second support component.

[0046] In this preferred embodiment, the display screen 4 is a vehicle-mounted central control screen, and the first bracket component 1 is connected to the vehicle component 8. The vehicle component 8 is a crossbeam.

[0047] The central control screen is a display screen on the center console, primarily showing car audio, navigation, vehicle information, and reversing camera content. It can be a single-point touchscreen or a multi-point touchscreen. In most models, the large color screen is located near the center console, but some newer models integrate it with the instrument cluster. A larger screen does not necessarily mean clearer viewing; clarity is affected by screen resolution. Adding a large color screen later may require disassembling and modifying the center console; improper handling can damage internal components and cause abnormal noises later on. Some models' large color screens not only display rich information but also offer touch-screen human-machine interaction. The car's central control unit controls the air conditioning, audio, and entertainment systems; its functions include central control, speed control, and individual control. The button functions on the car's central control unit include: 1. Electronic stability control; 2. Hazard warning lights; 3. Parking radar and camera; 4. Internal and external air circulation system; 5. Temperature zone synchronization function. The reasons why the central control screen is not lit are: 1. The battery is dead; 2. The display screen cable connector is loose; 3. The display screen is broken; 4. The power supply is abnormal; 5. The display screen cable is broken. The method for disassembling the central control screen is: 1. Use a plastic scraper to remove the decorative strip running across the front of the central control screen; 2. Remove the four screws around the central control screen; 3. Disconnect the connecting cable socket at the back of the central control screen to remove it. Currently, most central control screens are installed in a recess, and the recess walls can easily obstruct the rotation of the central control screen. The structure of this invention allows the central control screen to rotate while occupying less space.

[0048] Example 2

[0049] See Figure 2 As shown in the illustration, the rest is the same as in Embodiment 1, except that the rotation axis of the third support component 3 is parallel to the screen width direction of the display screen 4. Specifically, in this embodiment, the rotation axis of the third support component 3 is in the left-right direction. When the viewer is at a higher position, the display can be tilted upwards; when the viewer is at a lower position, the display can be tilted downwards. The display can be used at different heights. The aforementioned automotive component is a base plate.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
