Detailed Implementation

[0020] To provide a more detailed understanding of the features and technical content of the embodiments of this application, the implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this application. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0021] This application provides an adjustment device configured to adjust a vehicle display screen.

[0022] As shown in Figure 1, one end of the adjustment device is fixedly connected to a vehicle component, and the other end is fixedly connected to the display screen assembly 14. The adjustment device includes multiple interconnected telescopic components. This allows for free adjustment of the display screen's position via these interconnected telescopic components, satisfying the user's control over the display screen and adjusting its viewing angle, thus enhancing the user experience. In this application, the adjustment device adjusts the display screen's position through multiple interconnected telescopic components. One end of the retractable component is fixedly connected to the vehicle body, and the second end of the telescopic component is connected to the display screen. When the display screen is subjected to external force, the multiple telescopic components can move in unison to extend or retract, thereby adjusting the display screen's position and viewing angle.

[0023] As shown in Figures 1-2, in some embodiments, the multiple telescopic components include a first telescopic component 11, a second telescopic component 12, and a fixing plate 13. The first end of the first telescopic component 11 is fixedly connected to a vehicle component, and the second end of the first telescopic component 11 is connected to the first end of the second telescopic component 12 via the fixing plate 13. The second end of the second telescopic component 12 is fixedly connected to a display screen component 14. The multiple telescopic components are connected by the fixing plate, resulting in a simple structure. During the extension and retraction process, there are no excessive other components used to transmit force.

[0024] In some embodiments, the second end of the first telescopic component 11 is connected to the first surface of the fixed plate 13, and the first end of the second telescopic component 12 is connected to the second surface of the fixed plate 13, with the first and second surfaces facing away from each other. In this application, the fixed plate 13 can be configured to both fix the first telescopic component 11 and the second telescopic component 12, and also support the second telescopic component 12, achieving coordinated telescopic adjustment of two levels. It is understood that when the first telescopic component 11 is retracted to its maximum folded state, it can fit against the first surface of the fixed plate 13, and when the second telescopic component 12 is retracted to its maximum folded state, it can fit against the second surface of the fixed plate 13, thus minimizing space occupation after retraction.

[0025] In some optional embodiments, the first side of the fixing plate 13 is provided with a first mounting structure, the second side of the fixing plate 13 is provided with a second mounting structure, the first mounting structure is connected to the second end of the first telescopic component 11, and the second mounting structure is connected to the first end of the second telescopic component 12.

[0026] As shown in Figures 3-4, in some embodiments, the first mounting structure on the fixing plate 13 includes a first mounting hole 132 and a first slide rail 131, and a first slider 149 is provided on the first slide rail 131; the first telescopic component 11 includes two cross-arranged first arms 111 and second arms 110, the second end of the first arm 111 is fixedly connected to the first mounting hole 132 by a first fastener, and the second end of the second arm 110 is connected to the first slider 149, and the first slider 149 can move on the first slide rail 131 to drive the first telescopic component 11 to retract or expand. The first slide rail 131 in this application is configured as a silent slide rail. The first slide rail 131 can be fixed to the fixing plate 13 by fasteners or by adhesive. The telescopic component 11 includes two intersecting first arms 111 and second arms 110. A first mounting hole can be used to pass through a first fastener, such as a pivot, and is fixedly connected to the second end of the first arm 111 so that the first arm can rotate circumferentially along the pivot. The second end of the second arm 110 is welded or riveted to a first slider. The first slider can drive the second arm 110 to move on the first slide rail 131, thereby causing the first telescopic component 11 to retract or expand. The structure of the two intersecting arms is conducive to maximizing the opening angle of the first telescopic component, thereby improving stability and maximizing the telescopic distance of the telescopic arm.

[0027] As shown in Figures 3-4, in some optional embodiments, the second mounting structure on the fixing plate 13 includes a second mounting hole 134 and a second slide rail 133, and a second slider 150 is provided on the second slide rail 133; the second telescopic component 12 includes two intersecting third arms 121 and fourth arms 120, the first end of the third arm 121 is fixedly connected to the second mounting hole 134 through a second fastener, and the first end of the fourth arm 120 is connected to the second slider 150, and the second slider 150 can move on the second slide rail 133 to drive the second telescopic component 12 to retract or expand. The second slide rail 133 in this application is set as a silent slide rail. The second slide rail 133 can be fixed to the second side of the fixing plate 13 by fasteners or by adhesive. The second telescopic component 12 is composed of two identical cross-shaped third arms 121 and fourth arms 120. The cross-shaped arrangement is conducive to the maximum opening angle of the second telescopic component, which improves stability and maximizes the telescopic distance of the telescopic arm. The silent slide rail design in this application adopts a built-in ball slide rail scheme with Z-direction support, which has the advantages of high strength and quiet and smooth operation. It ensures high support strength in the vertical direction, effectively reduces noise during the extension and retraction of the adjustment device, and makes the movement smoother and more stable.

[0028] As shown in Figure 4, in some embodiments, a first damping member 112 is provided at the intersection of the first arm 111 and the second arm 110. The first damping member 112 has a spline opening to engage the first arm 111 and the second arm 110; or the first arm 111 and the second arm 110 have mounting through holes, and the damping shaft of the first damping member 112 is interference-fitted with the mounting through hole to connect the first arm 111 and the second arm 110.

[0029] In some embodiments, a second damping member 122 is provided at the intersection of the third arm 121 and the fourth arm 120. The second damping member 122 has a spline opening to engage the third arm 121 and the fourth arm 120; or the third arm 121 and the fourth arm 120 have mounting through holes, and the damping shaft of the second damping member 122 is interference-fitted with the mounting through hole to connect the third arm 121 and the fourth arm 120.

[0030] In this application, the first damping element 112 and the second damping element 122 are preferably disposed between the two intersecting support arms to set the optimal damping torque. When the damping force exceeds the damping force, the device moves; when it is less than the damping force, the device remains stationary. This provides functions of stopping, moving, and collapsing, greatly facilitating the needs of various scenarios. Furthermore, the adjustment device moves along a fixed straight line and will not sway to the surroundings. Collapsing can be achieved using damping. When the external force exceeds a certain limit, the vehicle display adjustment device will collapse, effectively preventing accidental injury to passengers caused by rigid fixation and effectively avoiding the potential safety risks brought about by rigid structures. The first damping element 112 is positioned between the two intersecting first arms 111 and 110 of the first telescopic assembly 11, and the second damping element 122 is positioned between the two intersecting third arms 121 and 120 of the second telescopic assembly 12. The first arms 111 and 110 form a triangle with the first damping element 112, and the third arms 121 and 120 form a triangle with the second damping element 122. The triangle has high stability, effectively improving the stability and reliability of the adjustment device. In particular, the damping torque can also be set. When the external force on the display adjustment device exceeds the damping force, it moves; when the external force on the display adjustment device is less than the damping force, it remains stationary. By setting the damping, it can achieve the functions of stopping, moving, and collapsing, allowing the display adjustment device to stay at any position during the extension or retraction process, greatly improving the applicability of the motion mechanism. The scheme of setting the damping in the middle of the intersecting arms in this application can also expand the extension and retraction length of the arms and improve the stability and reliability of the adjustment.

[0031] As shown in Figure 4, in some embodiments, the length of the first arm 111 is equal to the length of the second arm 110, and the length of the third arm 121 is equal to the length of the fourth arm 120; the length of the first arm 111 is greater than or equal to the length of the third arm 121. This provides more reliable stability when the adjustment device is fully extended, and when the adjustment device is fully retracted, the second telescopic group will not exceed the edge of the fixed plate, resulting in better concealment and a more aesthetically pleasing appearance. The two intersecting first arms 111 and 110 are centered on the first damping member 112, and the lengths of each segment of the first arm 111 and 110 to the four sides of the first damping member 112 are equal. The first arm 111, the second arm 110, the third arm 121, and the fourth arm 120 are made of high-strength aluminum alloy, with enhanced Z-axis strength. The adjustment device is thin yet strong, making it more stable and less prone to tipping or overturning under external force.

[0032] In some embodiments, the cross-sectional area of ​​the first arm 111 gradually decreases from both ends to the middle; and / or the cross-sectional area of ​​the second arm 110 gradually decreases from both ends to the middle.

[0033] In some embodiments, the cross-sectional area of ​​the third arm 121 gradually decreases from both ends to the middle, and / or the cross-sectional area of ​​the fourth arm 120 gradually decreases from both ends to the middle. It is understood that the design of the arms gradually decreasing in size from both ends to the middle facilitates the placement of minimal damping at the intersection of the arms, allowing for minimal space occupation after the adjustment device is retracted, resulting in a thinner and lighter device. The larger cross-sectional area at both ends of the arms provides better support when the adjustment device is extended, thereby improving the strength and reliability of the adjustment device.

[0034] In some alternative embodiments, the fixed plate 13 has a stepped cross-section in the Z direction. Grooves can be provided on the two opposite sides of the fixed plate, and the first and second telescopic components can be stored in the two grooves respectively after retraction. Through this design, the gradient structural feature of the fixed plate is effectively utilized to achieve the thinness of the adjustment device after retraction, that is, the thickness of the adjustment device after retraction is approximately equal to that of the fixed plate. The space occupied by the first and second telescopic components after retraction can be minimized or ignored. This structural feature can save storage space to the greatest extent.

[0035] As shown in Figure 4, this application proposes a display screen assembly, including a display screen 144, a first mounting plate 141, and an adjustment device, wherein the display screen 144 and the adjustment device are connected through the first mounting plate 141.

[0036] In some alternative embodiments, the first mounting plate 141 includes a first side and a second side disposed opposite to each other, the first side being connected to the adjustment device 1, and the display screen 144 being fixedly mounted on the second side of the first mounting plate 141.

[0037] As shown in Figures 1 and 3, in some optional embodiments, the first side of the first mounting plate 141 is provided with a third mounting structure, which is connected to the second end of the second telescopic component 12 of the adjustment device 1.

[0038] In some optional embodiments, the first mounting plate 141 has a third mounting structure on its first surface, including a third mounting hole 143 and a third slide rail 142. A third slider 151 is provided on the third slide rail 142. The second end of the third support arm 121 is connected to the third mounting hole 143 through a third damping member 148. The second end of the fourth support arm 120 is connected to the third slider 151. The third slider 151 can move on the third slide rail 142 to drive the second telescopic assembly 12 to retract or expand. The third slide rail 142 is fixed to the first surface of the first mounting plate 141 by fasteners or welding; the third mounting hole is fixedly connected to the second end of the third support arm 121, preferably through a third damping member 148, which preferably dampens a rotating shaft, so that the third support arm 121 can be fixed on the first mounting plate 141 and can rotate circumferentially along the rotating shaft of the third damping member 148; the second end of the fourth support arm 120 is connected to the third slider, so that when force is applied, the third slider can drive the second end of the fourth support arm 120 to move on the third slide rail 142. The third damping member 148 is a rotating shaft damper, fixedly connected to the second end of the third support arm 121 to adjust the tilt and rotation of the display screen, thereby adjusting the display viewing angle. The rotation range is limited by the long arc surface of the rotating shaft of the third damping member 148, which has high reliability.

[0039] As shown in Figure 4, in some optional embodiments, mounting bosses are provided at both ends of the back of the display screen 144 along the length of the display screen 144. A fourth mounting hole 145 is provided on the mounting boss, and the fourth mounting hole 145 is configured to allow a fourth fastener 147 to pass through and fix the display screen 144 to the first mounting plate 141. The display screen adjustment device provided in this application can achieve stepless telescopic adjustment over a long range with a fixed path. The adjustment device has a simple structure, high stability and reliability, is thin and light (almost the same thickness as the fixing plate), has a collapsible mechanism to prevent damage caused by rigid fixing, and can achieve wide-range adjustment and multi-angle rotation.

[0040] The X direction represents the vehicle's width, the Y direction represents the vehicle's front-to-back direction, and the Z direction represents the vehicle's height. Understandably, after the first telescopic component 11 is fully retracted, it fits against the first surface of the fixed plate 13, and after the second telescopic component 12 is fully retracted, it fits against the second surface of the fixed plate 13. The fixed plate 13, with its gradient design, can be accommodated on the two gradient surfaces of the retractable components. This gradient design allows for a thinner and lighter adjustment device. The gradient downward design distance of the fixed plate 13 is approximately equal to the folded storage distance of the first telescopic component 11. This gradient design of the fixed plate 13 fully utilizes the space occupied by the first-stage telescopic component 11, reducing the space occupied by the second-stage telescopic component 12. This results in a compressed thickness of the entire adjustment structure after retraction, enabling a thinner and lighter adjustment device, avoiding the need for additional storage space, and giving the display adjustment device the advantages of being thin, light, and space-saving.

[0041] This application also proposes a vehicle, including vehicle components and an adjustment device, wherein the vehicle components are connected to the adjustment device; or, including vehicle components and a display screen assembly, wherein the vehicle components are connected to the display screen assembly.

[0042] In some alternative embodiments, vehicle components include seats and / or a center console. One seat includes a seat body 2 connected to an adjustment device. The back of the seat body 2 has a receiving cavity 21, within which a second mounting plate 22 is provided. The second mounting plate 22 is connected to a first end of a first telescopic assembly 11. The receiving cavity 21 may be equipped with a locking mechanism and a handle, allowing for bilateral position fixation when the display screen 144 is retracted behind the seat back. It supports one-handed operation, is stable and reliable, and easy to use. With such a seat, after the display screen adjustment device is retracted, the adjustment device can be hidden and stored within the cavity of the seat back.

[0043] As shown in Figures 1-3, the second mounting plate 22 is provided with a fourth mounting structure, which includes a fifth mounting hole 222 and a fourth slide rail 221. A fourth slider 52 is provided on the fourth slide rail 221, and the fourth slide rail is fixed to the side of the second mounting plate 22 near the adjusting device. The first end of the first support arm 111 is fixedly connected to the fifth mounting hole 222 by a fifth fastener 223, and the first end of the second support arm 110 is connected to the fourth slider 52. The fourth slider 52 can move within the fourth slide rail 221 to drive the first telescopic component 11 to retract or expand. In this application, the display screen adjusting device can be hidden and stored in the receiving cavity 21 of the seat back, improving the overall aesthetics. The display screen adjusting device uses lightweight aluminum alloy, which has the advantages of high strength and good stability. After the support arm of the display screen adjusting device is retracted and folded, its thickness is basically the same as that of the fixing plate 13, resulting in high overall integration. The adjusting device occupies a small volume after retraction. The receiving cavity 22 of the seat back fully accommodates the display screen adjusting device, efficiently utilizing the seat back space and avoiding occupying too much seat space and structure.

[0044] Vehicles equipped with the aforementioned adjustment devices or display screen components can adjust the position and tilt angle of the display screen through a simple mechanical telescopic structure when the user moves back or reclines the seat, thus providing a better user experience. The damped telescopic adjustment device can flexibly collapse at any telescopic adjustment position, ensuring the safety of passengers in the cabin. The adjustment device with silent sliding rails can be adjusted silently or with controllable noise during telescopic adjustment. The use of folding arms effectively saves retractable storage space and has extremely high reliability, giving it strong potential market competitiveness.
