[0037] The following describes the embodiments of the present invention with reference to the accompanying drawings, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] In a first aspect, the utility model provides an adjustment device for adjusting a vehicle display screen.

[0040] like Figure 1 As shown, one end of the adjusting device is used to be fixedly connected to a vehicle component, and the other end of the adjusting device is used to be fixedly connected to a display screen 144. The adjusting device includes a plurality of telescopic components that are interconnected. In this way, the position of the display screen can be freely adjusted through a plurality of telescopic components that are interconnected to satisfy the user's control of the display screen and adjustment of the display screen viewing angle, thereby enhancing the user's experience. The adjusting device in the utility model adjusts the position of the display screen through a plurality of telescopic components that are interconnected. One end of the telescopic 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 an external force, the plurality of telescopic components can move in conjunction to extend or retract to adjust the position and viewing angle of the display screen.

[0041] like Figure 1-2 As shown, in some embodiments, the plurality of 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 used to be fixedly connected to a vehicle component, the second end of the first telescopic component 11 is used to be connected to the first end of the second telescopic component 12 through the fixing plate 13, and the second end of the second telescopic component 12 is used to be fixedly connected to a display screen 144. The plurality of telescopic components are connected through the fixing plate, and the structure is simple, and there are no excessive other components for transmitting force during the extension and retraction of the plurality of telescopic components.

[0042] In some embodiments, the second end of the first telescopic component 11 is connected to the first surface of the fixed plate 13, the first end of the second telescopic component 12 is connected to the second surface of the fixed plate 13, and the first surface and the second surface are arranged opposite to each other. In the utility model, the fixed plate 13 can be used to fix the connection and installation of the first telescopic component 11 and the second telescopic component 12, and can also support the second telescopic component 12 to achieve two-stage telescopic joint adjustment. It can be understood that when the first telescopic component 11 is contracted to the maximum folded state, it can be fitted with the first surface of the fixed plate 13, and when the second telescopic component 12 is contracted to the maximum folded state, it can be fitted with the second surface of the fixed plate 13, so as to take up the advantage of minimum space after contraction.

[0043] In some alternative embodiments, a first mounting structure is provided on the first surface of the fixing plate 13, and a second mounting structure is provided on the second surface of the fixing plate 13. The first mounting structure is connected to the second end of the first telescopic assembly 11, and the second mounting structure is connected to the first end of the second telescopic assembly 12.

[0044] As Figure 3-4 shown, in some embodiments, the first mounting structure on the fixing plate 13 includes a first mounting hole 132 and a first slide rail 131. A first slider 149 is provided on the first slide rail 131; the first telescopic assembly 11 includes two first arms 111 and second arms 110 that are cross - arranged. The second end of the first arm 111 is fixedly connected to the first mounting hole 132 through a first fastener, and the second end of the second arm 110 is connected to the first slider 149. The first slider 149 can move on the first slide rail 131 to drive the first telescopic assembly 11 to contract or expand. Preferably, the first slide rail 131 in the present utility model is set as a silent slide rail. The first slide rail 131 can be fixed to the fixing plate 13 by fasteners or by gluing. The telescopic assembly 11 includes two first arms 111 and second arms 110 that are cross - arranged. Preferably, the first mounting hole can pass through a first fastener, such as a rotating shaft, and be fixedly connected to the second end of the first arm 111, so that the first arm can rotate circumferentially along the rotating shaft. The second end of the second arm 110 is fixedly connected to the first slider by welding or riveting. The first slider can drive the second arm 110 to move on the first slide rail 131 to drive the first telescopic assembly 11 to contract or expand. The structure in which the two arms are cross - arranged is beneficial to the first telescopic assembly to open the included angle within the maximum range, and while improving the stability, the telescopic distance of the telescopic arm is maximally increased.

[0045] As Figure 3-4As shown, in some alternative embodiments, the second mounting structure on the fixed 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 assembly 12 includes two third arms 121 and fourth arms 120 that are cross - arranged. 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. The second slider 150 can move on the second slide rail 133 to drive the second telescopic assembly 12 to contract or expand. Preferably, the second slide rail 133 in the present utility model is set as a silent slide rail. The second slide rail 133 can be fixed on the second surface of the fixed plate 13 through fasteners or can be fixed by gluing. The second telescopic assembly 12 is composed of two identical third arms 121 and fourth arms 120 that are cross - arranged. The cross - arrangement is beneficial to the second telescopic assembly to open the included angle within the maximum range, while improving the stability and maximizing the telescopic distance of the telescopic arm. In the present utility model, the silent slide rail design adopts an internal ball slide rail scheme with Z - direction support, which has the advantages of high strength and quiet and smooth operation during use, ensuring high support strength in the vertical direction, more effectively reducing the noise during the telescopic process of the adjusting device, and making the movement more smooth and stable.

[0046] As Figure 4 As shown, 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 is provided with a spline opening to clamp the first arm 111 and the second arm 110; or the first arm 111 and the second arm 110 are provided with mounting through - holes, and the damping rotating shaft of the first damping member 112 is in interference fit with the mounting through - holes to connect the first arm 111 and the second arm 110.

[0047] 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 is provided with a spline opening to clamp the third arm 121 and the fourth arm 120; or the third arm 121 and the fourth arm 120 are provided with mounting through - holes, and the damping rotating shaft of the second damping member 122 is in interference fit with the mounting through - holes to connect the third arm 121 and the fourth arm 120.

[0048] In the present utility model, the first damping member 112 and the second damping member 122 are preferably arranged in the middle of two intersecting support arms to set the optimal torque of the damping. When the force applied to the damping exceeds the damping force, it moves, and when it is less than the damping force, it remains stationary. It can perform the functions of stopping, moving, and collapsing, greatly facilitating the use requirements in multiple scenarios. Moreover, the adjusting device moves along a fixed straight line and does not swing to the periphery. The use of damping enables collapse. When the external force exceeds a certain limit, the vehicle display screen adjusting device will collapse, effectively preventing rigid fixation from causing accidental injuries to passengers and effectively avoiding potential safety risks brought by rigid structures. The first damping member 112 is arranged at the middle position between the two intersecting first support arm 111 and the second support arm 110 of the first telescopic assembly 11, and the second damping member 122 is arranged at the middle position between the two intersecting third support arm 121 and the fourth support arm 120 of the second telescopic assembly 12. A triangle is formed between the first support arm 111 and the second support arm 110 and the first damping member 112, and a triangle is formed between the third support arm 121 and the fourth support arm 120 and the second damping member 122. The triangle has high stability, effectively improving the stability and reliability of the adjusting device. In particular, the damping torque can also be set. When the external force applied to the display screen adjusting device exceeds the damping force, it moves, and when the external force applied to the display screen adjusting device is less than the damping force, it remains stationary. By setting the damping, the functions of stopping, moving, and collapsing can be achieved, enabling the display screen adjusting device to stay at any position during the extension or contraction process, greatly improving the applicability of the moving mechanism. The present utility model uses the scheme of arranging damping in the middle of the intersecting support arms, which can also increase the telescopic length of the support arms and improve the stability, reliability, and adjustment of the adjustment.

[0049] As Figure 4 shown, in some embodiments, the length of the first support arm 111 is equal to the length of the second support arm 110, and the length of the third support arm 121 is equal to the length of the fourth support arm 120; the length of the first support arm 111 is greater than or equal to the length of the third support arm 121. In this way, when the adjusting device is fully extended, it has more reliable stability. When the adjusting device is fully retracted, the second telescopic assembly will not exceed the edge of the fixed plate, with good concealment and better aesthetics. Specifically, the two intersecting first support arm 111 and the second support arm 110 take the first damping member 112 as the center point, and the lengths of each section of the first support arm 111 and the second support arm 110 to the four sides of the first damping member 112 are equal; the first support arm 111 and the second support arm 110, and the third support arm 121 and the fourth support arm 120 are made of high-strength aluminum alloy, with enhanced Z-direction strength. The adjusting device is thin, light, and high-strength, and the adjusting device with this structure is more stable and not prone to tipping or flipping after being subjected to external forces.

[0050] In some embodiments, the cross-sectional area of the first support arm 111 gradually decreases from both ends to the middle of the first support arm 111; and / or the cross-sectional area of the second support arm 110 gradually decreases from both ends to the middle of the second support arm 110.

[0051] In some embodiments, the cross-sectional area of the third arm 121 gradually decreases from both ends to the middle of the third arm 121, and / or the cross-sectional area of the fourth arm 120 gradually decreases from both ends to the middle of the fourth arm 120. It can be understood that the design of the gradual decrease of the arm from both ends to the middle is beneficial to setting the minimum damping at the position where the arms cross in the middle, so as to be suitable for the adjusted device to occupy the smallest space after contraction, making the adjusted device thinner and lighter after contraction. The cross-sectional area of both ends of the arm is larger, so that the adjusted device has a better supporting effect after being unfolded, so as to improve the strength and reliability of the adjusted device.

[0052] In some alternative embodiments, the cross-section of the fixing plate 13 in the Z direction is stepped. Preferably, grooves can be provided on the two opposite faces of the fixing plate. After the first telescopic assembly and the second telescopic assembly are contracted, they can be respectively stored in the two grooves. Through such a design, the structural characteristics of the gradient of the fixing plate are effectively utilized to realize the characteristic of being thin and light after the adjustment device is contracted, that is, the thickness of the adjustment device after contraction is approximately equal to the thickness of the fixing plate, and the space occupied by the first telescopic assembly and the second telescopic assembly after contraction can be minimized or ignored. Such a structural characteristic can save the storage space to the greatest extent.

[0053] In a second aspect, as Figure 4 shown, the present invention provides a display screen assembly, including a display screen 144, a first mounting plate 141 and an adjustment device, and the display screen 144 and the adjustment device are connected through the first mounting plate 141.

[0054] In some alternative embodiments, the first mounting plate 141 includes a first side surface and a second side surface arranged opposite to each other. The first side surface is connected to the adjustment device 1, and the display screen 144 is fixedly mounted on the second side surface of the first mounting plate 141.

[0055] As Figure 1 、 Figure 3 shown, in some alternative embodiments, the first side surface of the first mounting plate 141 is provided with a third mounting structure, and the third mounting structure is connected to the second end of the second telescopic assembly 12 of the adjustment device 1.

[0056] In some alternative embodiments, a third mounting structure is provided on the first surface of the first mounting plate 141, 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 fourth support arm 120 is connected to the third mounting hole 143 through a third damping member 148. The second end of the third support arm 121 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 contract 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 fourth support arm 120, preferably through the third damping member 148. The third damping member 148 is preferably a damping rotating shaft, so that the fourth support arm 120 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 third support arm 121 is connected to the third slider, so that when a force is applied, the third slider can drive the second end of the third support arm 121 to move on the third slide rail 142. The third damping member 148 is a shaft-type damper, which is fixedly connected to the second end of the third support arm 121 to adjust the pitch rotation of the display screen, so as to achieve the purpose of adjusting the display angle. The rotation range is limited by the long arc surface of the rotating shaft of the third damping member 148, and the reliability is high.

[0057] As Figure 4 shown, in some alternative embodiments, mounting bosses are provided at both ends of the back surface of the display screen 144 along the length direction of the display screen 144. Fourth mounting holes 145 are provided on the mounting bosses. The fourth mounting holes 145 are used for passing through fourth fasteners 147 to fixedly connect the display screen 144 and the first mounting plate 141. A display screen adjusting device provided by the present utility model can achieve stepless telescopic adjustment within a relatively long range and with a fixed path. The adjusting device has a simple structure, high stability and reliability, is thin and light, can be almost as thick as the fixing plate, has a collapse mechanism to prevent damage caused by rigid fixation, and can achieve wide-range adjustment and multi-angle rotation.

[0058] The X direction is the vehicle body width direction, the Y direction is the vehicle body front-rear direction, and the Z direction is the vehicle body height direction. It can be understood that 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 a gradient can accommodate the retracted components on the two gradient surfaces of the fixed plate 13 after the retraction components are retracted. Such a gradient design can make the adjusting device thinner and lighter. Specifically, the gradient sinking design distance of the fixed plate 13 is approximately equal to the folding and storage distance of the first telescopic component 11. The gradient design of the fixed plate 13 can make full use of the space occupied by the first-stage telescopic component 11, reduce the space occupied by the second-stage telescopic component 12, compress the thickness of the entire adjusting structure after retraction, realize the thinning and lightening of the adjusting device, avoid occupying additional storage space, and make the display screen adjusting device have the advantages of being thin, light, and space-saving.

[0059] In a third aspect, the present invention further provides a vehicle, including a vehicle component and an adjusting device, where the vehicle component is connected to the adjusting device; or, including a vehicle component and a display screen assembly, where the vehicle component is connected to the display screen assembly.

[0060] In some alternative embodiments, the vehicle component includes a seat and / or a center console. Specifically, a seat includes a seat body 2, the seat body 2 is connected to the adjusting device, a receiving cavity 21 is provided on the back of the seat body 2, and a second mounting plate 22 is provided in the receiving cavity 21. The second mounting plate 22 is connected to the first end of the first telescopic component 11. Preferably, a locking mechanism and a handle can be provided in the receiving cavity 21. When the display screen 144 is retracted to the back of the seat, bilateral position fixation can be performed, supporting single-handed operation to open, which is stable, reliable, and convenient to use. Such a seat can hide and store the adjusting device in the cavity on the back of the seat after the display screen adjusting device is retracted.

[0061] Such as Figure 1 - Figure 3As shown in the figure, the second mounting plate 22 is provided with a fourth mounting structure, and the fourth mounting structure 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 one side of the second mounting plate 22 close to the adjusting device; the first end of the first arm 111 is fixedly connected to the fifth mounting hole 222 through a fifth fastener 223, the first end of the second arm 110 is connected to the fourth slider 52, and the fourth slider 52 can move within the fourth slide rail 221 to drive the first telescopic assembly 11 to contract or expand. In the seat of the present utility model, the display screen adjusting device can be hidden and stored in the accommodation cavity 21 of the seat back, improving the overall aesthetics. The display screen adjusting device uses lightweight aluminum alloy, having the advantages of high strength and good stability. After the arms of the display screen adjusting device are contracted and folded, the thickness is basically the same as that of the fixing plate 13, with a high overall integration degree. The adjusting device has the advantages of small occupied volume after contraction. The accommodation cavity 22 of the seat back fully accommodates the display screen adjusting device, efficiently utilizing the space of the seat back and avoiding occupying too much seat space and structure.

[0062] For a vehicle configured with the above-mentioned adjusting device or display screen assembly, when the user moves the seat backward or reclines the seat, the position and pitch angle of the display screen can be adjusted through a simple mechanical telescopic structure to meet the better operation and experience of the user; the telescopic adjusting device provided with damping can be flexibly crushed at any telescopic adjustment position, highly ensuring the safety of passengers in the cabin. The adjusting device provided with a silent slide rail can be adjusted silently or with controllable noise during the telescopic adjustment process. The use of folding arms effectively saves the contraction and storage space and has extremely high reliability, having strong potential market competitiveness.
