[0046] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0047] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0048] In the description of the present invention, "plurality" means two or more.

[0049] First, the vehicle display terminal 2 according to an embodiment of the present invention is described with reference to the accompanying drawings. The vehicle display terminal 2 includes a vehicle display terminal adjustment device 1, an external main flexible screen 200 and an external auxiliary screen 300.

[0050] The following describes a vehicle-mounted display terminal adjustment device 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0051] like Figure 1-Figure 7 As shown, the vehicle-mounted display terminal adjustment device 1 includes a supporting bracket 100 and a driving mechanism 400 .

[0052] The support bracket 100 has a first surface 110 and a second surface 120 opposite to each other. The support bracket 100 includes a main support 130 and an auxiliary support 140. The auxiliary support 140 is flippable relative to the main support 130. The external main flexible screen 200 is mounted on the first surface 110 of the support bracket 100 and laid on the main support 130 and the auxiliary support 140. The external auxiliary screen 300 is mounted on the second surface 120 of the support bracket 100 and laid on the auxiliary support 140. The driving mechanism 400 is connected to the main support 130 and the auxiliary support 140.

[0053] Among them, when the auxiliary bracket 140 is flipped relative to the main bracket 130 and unfolded to one side in the length direction or one side in the width direction of the main bracket 130, the external main flexible screen 200 is unfolded to form a user interface for outputting graphic information; when the auxiliary bracket 140 is flipped relative to the main bracket 130 and folded to one side in the thickness direction of the main bracket 130, the external main flexible screen 200 is folded between the main bracket 130 and the auxiliary bracket 140, and the external auxiliary screen 300 forms a user interface for outputting graphic information.

[0054] For example, the external main flexible screen 200 may include an organic electroluminescence display (OLED). The flexibility of the external auxiliary screen 300 is less than that of the external main flexible screen 200, that is, the external main flexible screen 200 is easier to fold, and the external auxiliary screen 300 may be flexible or inflexible, that is, the external auxiliary screen 300 can be bent or not. In addition, the first surface 110 is formed with a positioning groove for accommodating the external main flexible screen 200, and the second surface 120 of the external auxiliary screen 300 is formed with a positioning groove for accommodating the external auxiliary screen 300. The positioning groove can not only position the external main flexible screen 200 and the external auxiliary screen 300, but also protect the edges of the external main flexible screen 200 and the edges of the external auxiliary screen 300 from collision damage. The first surface 110 and the second surface 120 may be located on opposite sides of the thickness direction of the supporting bracket 100. The auxiliary bracket 140 may be directly or indirectly connected to the main bracket 130.

[0055] In addition, when the external main flexible screen 200 forms a user interface, the external main flexible screen 200 can display navigation information, touch buttons, entertainment images and other graphic information. When the external auxiliary screen 300 forms a user interface, the external auxiliary screen 300 is mainly used to display touch buttons, such as air conditioning temperature and wind speed adjustment buttons.

[0056] According to the vehicle-mounted display terminal adjustment device 1 of an embodiment of the present invention, the external main flexible screen 200 is installed on the first surface 110 of the supporting bracket 100 and laid on the main bracket 130 and the auxiliary bracket 140, and the external auxiliary screen 300 is installed on the second surface 120 of the supporting bracket 100 and laid on the auxiliary bracket 140, that is, the display area of ​​the external main flexible screen 200 is larger than the display area of ​​the external auxiliary screen 300.

[0057] In addition, the driving mechanism 400 is connected to the main support 130 and the auxiliary support 140, such as Figure 1 As shown, when the auxiliary bracket 140 is flipped relative to the main bracket 130 and unfolded to one side of the length direction or one side of the width direction of the main bracket 130, the external main flexible screen 200 unfolds to form a user interface for outputting graphic information. It should be noted that when the external main flexible screen 200 is unfolded, the angle between the main bracket 130 and the auxiliary bracket 140 can be 180°. In this state, the user interface is a plane; the angle between the main bracket 130 and the auxiliary bracket 140 can be greater than 180°. In this state, the angle of the user interface is greater than 180°; the angle between the main bracket 130 and the auxiliary bracket 140 can be less than 180°. In this state, the angle of the user interface is less than 180°. In other words, the vehicle-mounted display terminal adjustment device 1 of the embodiment of the present invention does not need to limit the state of the external main flexible screen 200 after unfolding, and it is sufficient to ensure that the user interface formed by the external main flexible screen 200 can be clearly observed and effectively contacted by the user. Effective contact means that the user can touch any position on the user interface. In this way, the vehicle-mounted display terminal adjustment device 1 has low requirements on the installation environment, has higher applicability, and can be set differently according to user needs.

[0058] like Figure 2 As shown, when the auxiliary bracket 140 is flipped relative to the main bracket 130 and folded to one side in the thickness direction of the main bracket 130, the external main flexible screen 200 is folded between the main bracket 130 and the auxiliary bracket 140, and the external auxiliary screen 300 forms a user interface for outputting graphic information. In this way, the vehicle-mounted display terminal adjustment device 1 can switch between the external main flexible screen 200 forming the user interface and the external auxiliary screen 300 forming the user interface. When the external main flexible screen 200 forms the user interface, the vehicle-mounted display terminal adjustment device 1 has a larger user interface and can display more complex and larger area images. When the external auxiliary screen 300 forms the user interface, the cross-sectional area of ​​the vehicle-mounted display terminal adjustment device 1 is smaller and occupies less installation space to improve space utilization, wherein the cross-sectional area of ​​the vehicle-mounted display terminal adjustment device 1 is parallel to the cross-sectional area of ​​the main bracket 130 and perpendicular to the thickness direction of the main bracket 130.

[0059] In this way, the vehicle-mounted display terminal adjustment device 1 according to the embodiment of the present invention can not only switch between the unfolded state and the folded state, but also has the advantages of high automation and smooth movement.

[0060] The vehicle-mounted display terminal 2 according to the present invention has the advantages of high automation, smooth movement, etc. by utilizing the vehicle-mounted display terminal adjustment device 1 according to the above embodiment of the present invention.

[0061] In some embodiments of the present invention, the control unit is connected to the driving mechanism 400, and is used to control the driving mechanism 400 to drive the auxiliary bracket 140 to flip relative to the main bracket 130, wherein the control unit can receive a user input signal, for example, the input signal can be input through a touch key on the user interface, or input through a remote control, or input through a button on the vehicle. The control unit controls the driving mechanism 400 to drive at least one of the auxiliary bracket 140 and the main bracket 130 to move according to the input signal, so as to change the relative position of the auxiliary bracket 140 and the main bracket 130. In this way, the operation of flipping the auxiliary bracket 140 relative to the main bracket 130 does not need to be manually implemented, the degree of automation is high, the positioning is more accurate, the rotation speed is more uniform, and the movement stability is better.

[0062] According to some specific embodiments of the present invention, Figure 3 As shown, the auxiliary bracket 140 includes a first auxiliary bracket 141 and a second auxiliary bracket 142, and the first auxiliary bracket 141 and the second auxiliary bracket 142 are respectively flippably mounted on opposite sides of the main bracket 130. The external auxiliary screen 300 includes a first external auxiliary screen 310 and a second external auxiliary screen 320. The first external auxiliary screen 310 is mounted on the second surface 120 of the load-bearing bracket 100 and laid on the first auxiliary bracket 141, and the second external auxiliary screen 320 is mounted on the second surface 120 of the load-bearing bracket 100 and laid on the second auxiliary bracket 142. When the auxiliary bracket 140 is folded relative to the main bracket 130, the first auxiliary bracket 141 and the second auxiliary bracket 142 are aligned.

[0063] By dividing the auxiliary bracket 140 into the first auxiliary bracket 141 and the second auxiliary bracket 142, the center of gravity of the first auxiliary bracket 141 is closer to the rotation axis of the first auxiliary bracket 141, and the center of gravity of the second auxiliary bracket 142 is closer to the rotation axis of the second auxiliary bracket 142, so that the rotation of the first auxiliary bracket 141 and the second auxiliary bracket 142 is more stable. In addition, since the cross-sectional area of ​​the first auxiliary bracket 141 and the cross-sectional area of ​​the second auxiliary bracket 142 are both smaller than the cross-sectional area of ​​the auxiliary bracket 140, the movement tracks of the first auxiliary bracket 141 and the second auxiliary bracket 142 are smaller and are less likely to interfere with other objects, so that the vehicle-mounted display terminal adjustment device 1 is arranged on the entire vehicle.

[0064] In addition, the external auxiliary screen 300 is divided into a first external auxiliary screen 310 and a second external auxiliary screen 320. The external auxiliary screen 300 is more compatible with the auxiliary bracket 140, and the external auxiliary screen 300 is easy to disassemble and assemble, and the external auxiliary screen 300 is not easy to be broken.

[0065] Specifically, the size of the first auxiliary bracket 141 in the first direction (the direction indicated by the arrow A in the figure), the size of the second auxiliary bracket 142 in the first direction and the size of the main bracket 130 in the first direction are equal to each other, and the sum of the size of the first auxiliary bracket 141 in the second direction (the direction indicated by the arrow B in the figure) and the size of the second auxiliary bracket 142 in the second direction is equal to the size of the main bracket 130 in the second direction. The first direction is perpendicular to the second direction, and the flip axis of the first auxiliary bracket 141 and the flip axis of the second auxiliary bracket 142 extend along the second direction.

[0066] In this way, when the external main flexible screen 200 is folded, the first auxiliary bracket 141 and the second auxiliary bracket 142 are roughly in contact with the main bracket 130, and the first auxiliary bracket 141 and the second auxiliary bracket 142 can fully cover the external main flexible screen 200, so that after the external main flexible screen 200 is folded, the vehicle-mounted display terminal adjustment device 1 is flatter.

[0067] Accordingly, the driving mechanism 400 is multiple and includes at least a first driving mechanism 401 and a second driving mechanism 402. The first driving mechanism 401 is connected to the first auxiliary support 141 and the main support 130, and is used to drive the first auxiliary support 141 to flip relative to the main support 130. The second driving mechanism 402 is connected to the second auxiliary support 142 and the main support 130, and is used to drive the second auxiliary support 142 to flip relative to the main support 130. The first driving mechanism 401 and the second driving mechanism 402 are both connected to the control unit.

[0068] In other words, the first auxiliary bracket 141 is driven solely by the first driving mechanism 401, and the second auxiliary bracket 142 is driven solely by the second driving mechanism 402. This can not only effectively avoid interference between the first auxiliary bracket 141 and the second auxiliary bracket 142, but also the first auxiliary bracket 141 and the second auxiliary bracket 142 can be moved independently, and the overall controllability of the vehicle-mounted display terminal adjustment device 1 is higher.

[0069] According to some specific embodiments of the present invention, Figure 6 As shown, the driving mechanism 400 includes a folding bracket 410, a first folding frame 420, a second folding frame 430 and a driving module.

[0070] The first folding frame 420 and the second folding frame 430 are installed on the folding bracket 410, the first folding frame 420 is connected to the main bracket 130, for example, by threaded fasteners (bolts and screws, etc.), the second folding frame 430 is connected to the auxiliary bracket 140, for example, by threaded fasteners (bolts and screws, etc.), and the driving module is installed on the folding bracket 410, and the driving module drives the first folding frame 420 and the second folding frame 430 to rotate relative to the folding bracket 410.

[0071] For example, the main bracket 130 and the auxiliary bracket 140 can be provided with folding grooves, and the folding groove of the main bracket 130 cooperates with the first folding frame 420, and the folding groove of the auxiliary bracket 140 cooperates with the second folding frame 430, so that the surface of the first folding frame 420, the surface of the second folding frame 430 and the first surface 110 are located in the same plane, avoiding the first folding frame 420 and the second folding frame 430 causing the external main flexible screen 200 to be unable to be installed flatly, and providing more comprehensive support for the external main flexible screen 200.

[0072] Since both the main bracket 130 and the auxiliary bracket 140 have a certain thickness, if the first folding frame and the second folding frame are directly rotatably connected, or the first folding frame and the second folding frame are formed into one piece and then rotatably connected to one of the main bracket and the auxiliary bracket, when the external main flexible screen is folded, the side of the main bracket connected to the driving mechanism and the side of the auxiliary bracket connected to the driving mechanism will interfere with each other, thus causing a large gap between the main bracket and the auxiliary bracket. However, when the external main flexible screen 200 of the vehicle display terminal adjustment device 1 of the embodiment of the present invention is folded, because the folding bracket 410 is provided, and the first folding bracket 420 and the second folding bracket 430 are installed on the folding bracket 410, the folding bracket 410 can eliminate the interference between the main bracket 130 and the auxiliary bracket 140 to a certain extent, so the gap between the main bracket 130 and the auxiliary bracket 140 is small, and the main bracket 130 and the auxiliary bracket 140 fit more closely.

[0073] In addition, by providing a folding bracket 410, an installation support is provided for the driving module, so that the driving module does not need to be installed on the main bracket 130 and the auxiliary bracket 140, thereby increasing the installation space for the external main flexible screen 200 and the external auxiliary screen 300, and the driving module is not easy to interfere with the external main flexible screen 200 and the external auxiliary screen 300 when working.

[0074] Furthermore, the driving mechanism 400 also includes a first transmission shaft 440 and a second transmission shaft 450, the folding bracket 410 is provided with a first mounting hole 411 and a second mounting hole 412, the first folding frame 420 is provided with a first folding ear 421, and the second folding frame 430 is provided with a second folding ear 431, the first transmission shaft 440 is transmission-connected to the first folding ear 421 and passes through the first mounting hole 411, and the second transmission shaft 450 is transmission-connected to the second folding ear 431 and passes through the second mounting hole 412.

[0075] For example, the first folding ear 421 and the second folding ear 431 can both be provided with through holes, the first transmission shaft 440 extends into the through hole of the first folding ear 421, the first transmission shaft 440 and the through hole of the first folding ear 421 can be interference fit and have a clearance fit with the first mounting hole 411, the second transmission shaft 450 extends into the through hole of the second folding ear 431, the second transmission shaft 450 and the through hole of the second folding ear 431 can be interference fit and have a clearance fit with the second mounting hole 412.

[0076] Furthermore, both the first transmission shaft 440 and the second transmission shaft 450 can be bolts, one end of the first transmission shaft 440 is stopped at one end of the folding bracket 410 through a bolt cap, the other end of the first transmission shaft 440 is threadedly engaged with the first nut, and the first nut is stopped at the other end of the folding bracket 410, that is, the bolt cap of the first transmission shaft 440 and the first nut clamp the folding bracket 410 to ensure that the first transmission shaft 440 is fixed in a relative position to the folding bracket 410 in its axial direction.

[0077] One end of the second transmission shaft 450 is stopped at one end of the folding bracket 410 through a bolt nut, and the other end of the second transmission shaft 450 is threadedly engaged with the second nut, and the second nut is stopped at the other end of the folding bracket 410, that is, the bolt nut of the second transmission shaft 450 and the second nut clamp the folding bracket 410 to ensure that the first transmission shaft 440 is fixed in a relative position with the folding bracket 410 in its axial direction.

[0078] In this way, the first transmission shaft 440 can rotate synchronously with the first folding frame 420 and rotate relative to the folding bracket 410, and the second transmission shaft 450 can rotate synchronously with the second folding frame 430 and rotate relative to the folding bracket 410, so as to facilitate flipping between the main bracket 130 and the auxiliary bracket 140.

[0079] In addition, the first folding ear 421 can be multiple and arranged at axial intervals along the first transmission shaft 440, and the second folding ear 431 can be multiple and arranged at axial intervals along the second transmission shaft 450. The power transmission efficiency between the first folding frame 420 and the first transmission shaft 440 is higher, and the power transmission efficiency between the second folding frame 430 and the second transmission shaft 450 is higher.

[0080] There may be two first transmission shafts 440, and the two first transmission shafts 440 are respectively matched with the folding bracket 410 from both ends of the folding bracket 410, and each first transmission shaft 440 is connected with a corresponding first nut and fixed with the folding bracket 410 in the axial direction of the first transmission shaft 440. There may be two second transmission shafts 450, and the two second transmission shafts 450 are respectively matched with the folding bracket 410 from both ends of the folding bracket 410, and each second transmission shaft 450 is connected with a corresponding second nut and fixed with the folding bracket 410 in the axial direction of the second transmission shaft 450.

[0081] Optionally, the driving module includes a driving motor 510 , a worm 520 , a worm wheel 530 , a steering gear 540 , a first transmission gear 550 , a first output gear 560 , a second transmission gear 570 and a second output gear 580 .

[0082] The driving motor 510 is mounted on the folding bracket 410 and has a motor shaft 511. The worm 520 is transmission-connected to the motor shaft 511. The worm wheel 530 is rotatably mounted on the folding bracket 410 and meshes with the worm 520. The steering gear 540 is rotatably mounted on the folding bracket 410 and meshes with the worm wheel 530. The axial direction of the steering gear 540 is parallel to the axial direction of the motor shaft 511. The first transmission gear 550 is rotatably mounted on the folding bracket 410. The first output gear 560 is transmission-connected to the first transmission shaft 440 and meshes with the first transmission gear 550. The second transmission gear 570 is rotatably mounted on the folding bracket 410. The second output gear 580 is transmission-connected to the second transmission shaft 450 and meshes with the second transmission gear 570. Among them, the first transmission gear 550 meshes with the second transmission gear 570, and the steering gear 540 is transmission-connected to one of the first transmission gear 550 and the second transmission gear 570.

[0083] For example, the worm 520 can be sleeved on the motor shaft 511, and the motor shaft 511 can be interference fit with the worm 520. The worm wheel 530 and the worm 520 can be self-locked when the drive motor 510 is static, so as to avoid relative rotation between the worm wheel 530 and the worm 520 when the drive motor 510 is not driving, thereby improving the position stability of the worm wheel 530 and the worm 520, which is conducive to keeping the vehicle-mounted display terminal adjustment device 1 in the current state when the drive motor 510 is not working, so that the user interface of the external main flexible screen 200 and the external auxiliary screen 300 is more stable.

[0084] The steering gear 540 can be a bevel gear to change the direction of power transmission, wherein the rotation axis of the steering gear 540, the rotation axis of the motor shaft 511 and the rotation axis of the auxiliary bracket 140 can coincide with each other, thereby facilitating the relative rotation between the main bracket 130 and the auxiliary bracket 140.

[0085] The first output gear 560 can be sleeved on the first transmission shaft 440 and have an interference fit with the first transmission shaft 440, that is, when the first output gear 560 rotates, it drives the first transmission shaft 440 to rotate, and the first transmission shaft 440 drives the first folding frame 420 to rotate relative to the folding bracket 410. The second output gear 580 can be sleeved on the second transmission shaft 450 and have an interference fit with the second transmission shaft 450, that is, when the second output gear 580 rotates, it drives the second transmission shaft 450 to rotate, and the second transmission shaft 450 drives the second folding frame 430 to rotate relative to the folding bracket 410.

[0086] Through multiple meshing transmissions among the worm 520, the worm wheel 530, the steering gear 540, the first transmission gear 550, the first output gear 560, the second transmission gear 570 and the second output gear 580, the rotational speed of the first transmission shaft 440 input and the rotational speed of the second transmission shaft 450 input can both be less than the rotational speed of the motor shaft 511 output, so that the relative movement of the auxiliary bracket 140 is smoother.

[0087] Optionally, the driving mechanism 400 also includes a third transmission shaft 551 and a fourth transmission shaft 571, the folding bracket 410 is provided with a third mounting hole 413 and a fourth mounting hole 414, the third transmission shaft 551 passes through the third mounting hole 413 and is connected to the first transmission gear 550, the fourth transmission shaft 571 passes through the fourth mounting hole 414 and is connected to the second transmission gear 570, and the steering gear 540 is connected to the third transmission shaft 551 and the fourth transmission shaft 571.

[0088] For example, the first transmission gear 550 is sleeved on the third transmission shaft 551, the third transmission shaft 551 and the first transmission gear 550 can be interference fit and have a clearance fit with the third mounting hole 413, the second transmission gear 570 is sleeved on the fourth transmission shaft 571, the fourth transmission shaft 571 and the second transmission gear 570 can be interference fit and have a clearance fit with the fourth mounting hole 414.

[0089] Furthermore, the third transmission shaft 551 and the fourth transmission shaft 571 can both be bolts, one end of the third transmission shaft 551 is stopped at one end of the folding bracket 410 through a bolt nut, the other end of the third transmission shaft 551 is threadedly engaged with the third nut, and the third nut is stopped at the other end of the folding bracket 410, that is, the bolt nut of the third transmission shaft 551 and the third nut clamp the folding bracket 410 to ensure that the relative position of the third transmission shaft 551 and the folding bracket 410 in its axial direction is fixed.

[0090] One end of the fourth transmission shaft 571 is stopped at one end of the folding bracket 410 through a bolt nut, and the other end of the fourth transmission shaft 571 is threadedly engaged with the fourth nut, and the fourth nut is stopped at the other end of the folding bracket 410, that is, the bolt nut and the fourth nut of the fourth transmission shaft 571 clamp the folding bracket 410 to ensure that the relative position of the fourth transmission shaft 571 and the folding bracket 410 in its axial direction is fixed.

[0091] The steering gear 540 can be sleeved on one of the third transmission shaft 551 and the fourth transmission shaft 571. Assuming that the steering gear 540 is sleeved on the third transmission shaft 551, the steering gear 540 sleeve is interference fit with the third transmission shaft 551, so that the steering gear 540 sleeve drives the first transmission gear 550 to rotate through the third transmission shaft 551, the first transmission gear 550 drives the second transmission gear 570 to rotate, and the second transmission gear 570 drives the fourth transmission shaft 571 and the second output gear 580 to rotate relative to the folding bracket 410. When the steering gear 540 is sleeved on the fourth transmission shaft 571, the movement process of the steering gear 540 sleeved on the third transmission shaft 551 can be referred to.

[0092] In some embodiments of the present invention, Figure 6 As shown, the folding bracket 410 is provided with a plurality of partition plates 460 spaced apart along the length direction thereof, and the plurality of partition plates 460 define a plurality of accommodation spaces on the folding bracket 410, and the plurality of accommodation spaces at least include a first accommodation space 461, a second accommodation space 462, and a third accommodation space 463. Among them, the first folding ear 421 and the second folding ear 431 are located in the first accommodation space 461, the worm gear 530 and the steering gear 540 are located in the second accommodation space 462, and the first transmission gear 550, the first output gear 560, the second transmission gear 570, and the second output gear 580 are located in the third accommodation space 463.

[0093] For example, the first mounting hole 411, the second mounting hole 412, the third mounting hole 413 and the fourth mounting hole 414 can be set on the partition plate 460, and the third accommodating space 463 can be multiple, and the multiple third accommodating spaces 463, the multiple first folding ears 421 and the multiple second folding ears 431 correspond one to one.

[0094] In this way, multiple partition plates 460 are set up to avoid interference between the first folding ear 421, the second folding ear 431 and the various components in the driving module and ensure the stability of movement, and can also provide installation and support for the first transmission shaft 440, the second transmission shaft 450, the third transmission shaft 551 and the fourth transmission shaft 571, thereby facilitating the rotation of the first folding ear 421, the second folding ear 431 and the various components in the driving module.

[0095] Specifically, the driving mechanism 400 further includes a first cover plate 470, the folding bracket 410 is provided with a motor slot 415, the driving motor 510 is installed in the motor slot 415, the first cover plate 470 is installed on the folding bracket 410 and covers the driving motor 510, and the first cover plate 470 can be installed on the folding bracket 410 by threaded fasteners (such as bolts and screws). Among them, the first cover plate 470 is an arc-shaped cover plate, and the motor slot 415 is an arc-shaped slot, that is, the driving motor 510 is accommodated by the first cover plate 470 and the motor slot 415. In this way, the first cover plate 470 and the motor slot 415 do not need to be set too large, and the relative positions of the driving motor 510 and the folding bracket 410 can be fixed.

[0096] For example, there are two driving mechanisms 400 between the first auxiliary support 141 and the main support 130, and the ends of the two driving mechanisms 400 with the driving motors 510 are arranged opposite to each other, so that the first cover plates 470 of the two driving mechanisms 400 can be arranged as one body to reduce the installation and processing steps. In addition, the first folding frames 420 of the two driving mechanisms 400 are farther apart, and the second folding frames 430 of the two driving mechanisms 400 are farther apart, which not only makes the connection with the auxiliary support 140 and the main support 130 uniform, but also makes it less likely to interfere.

[0097] Optionally, the driving mechanism 400 further includes a second cover plate 480, which is mounted on the folding bracket 410. The worm wheel 530 has a rotating shaft, and both ends of the rotating shaft are rotatably mounted on the folding bracket 410 and the second cover plate 480, respectively. The second cover plate 480 can be mounted on the folding bracket 410 by threaded fasteners (such as bolts and screws). In this way, while ensuring that the worm wheel 530 can rotate, the worm wheel 530 is positioned in its axial direction, and the positioning accuracy of the worm wheel 530 is high.

[0098] According to some specific embodiments of the present invention, Figure 7 As shown, the vehicle-mounted display terminal adjustment device 1 also includes a limiting mechanism 600, which is connected to the main bracket 130 and the auxiliary bracket 140. The limiting mechanism 600 limits the angle range of the auxiliary bracket 140 flipping relative to the main bracket 130, that is, the limiting mechanism 600 limits the maximum angle and the minimum angle between the auxiliary bracket 140 and the main bracket 130.

[0099] The working state of the vehicle-mounted display terminal adjustment device 1 when it moves to the limit position is described in conjunction with the accompanying drawings:

[0100] When the angle between the auxiliary bracket 140 and the main bracket 130 is at its maximum value, if the driving motor 510 has a tendency to drive the auxiliary bracket 140 and the main bracket 130 to continue to expand the above angle, since the auxiliary bracket 140 and the main bracket 130 cannot move relative to each other at this time, firstly, the clearance between the gears in the driving module is gradually eliminated, and then the driving motor 510 is blocked, and at this time, the driving motor 510 can be powered off and stop outputting power;

[0101] When the angle between the auxiliary bracket 140 and the main bracket 130 is at the minimum value, if the driving motor 510 has a tendency to drive the auxiliary bracket 140 and the main bracket 130 to continue to reduce the above angle, since the auxiliary bracket 140 and the main bracket 130 cannot move relative to each other at this time, the gaps between the gears in the driving module are gradually eliminated first, and then the driving motor 510 is blocked. At this time, the driving motor 510 can be powered off and stop outputting power.

[0102] It should be noted that, by limiting the minimum angle between the auxiliary bracket 140 and the main bracket 130 through the limiting mechanism 600, it is possible to prevent the relative movement of the auxiliary bracket 140 and the main bracket 130 from being blocked by the surfaces of the external main flexible screen 200 abutting against each other when the external main flexible screen 200 is folded, thereby reducing the probability of the external main flexible screen 200 being broken, which is beneficial to increasing the service life of the vehicle-mounted display terminal adjustment device 1.

[0103] Furthermore, the limiting mechanism 600 includes a limiting bracket 610 , a first limiting bracket 620 and a second limiting bracket 630 .

[0104] The limiting bracket 610 is provided with a first limiting groove 611 and a second limiting groove 612. The first limiting bracket 620 is connected to the main bracket 130 and is rotatably installed on the limiting bracket 610. The first limiting bracket 620 is provided with a first limiting protrusion 621, and the first limiting protrusion 621 extends into the first limiting groove 611. The second limiting bracket 630 is connected to the auxiliary bracket 140. The second limiting bracket 630 is rotatably installed on the limiting bracket 610. The second limiting bracket 630 is provided with a second limiting protrusion 631, and the second limiting protrusion 631 extends into the second limiting groove 612.

[0105] For example, the first limiting frame 620 can be installed on the main bracket 130 by threaded fasteners (bolts and screws), and the second limiting frame 630 can be installed on the auxiliary bracket 140 by threaded fasteners (bolts and screws). The first limiting groove 611 and the second limiting groove 612 can be arc grooves, the first limiting groove 611 can guide the first limiting protrusion 621, and the second limiting groove 612 can guide the second limiting protrusion 631.

[0106] When the first limiting protrusion 621 stops at one end of the first limiting groove 611 close to the second limiting groove 612, and the second limiting protrusion 631 stops at one end of the second limiting groove 612 close to the first limiting groove 611, the angle between the main bracket 130 and the auxiliary bracket 140 is at a minimum value;

[0107] When the first limiting protrusion 621 stops at the end of the first limiting groove 611 away from the second limiting groove 612, and the second limiting protrusion 631 stops at the end of the second limiting groove 612 away from the first limiting groove 611, the angle between the main bracket 130 and the auxiliary bracket 140 is at its maximum value.

[0108] It can be understood that the above two states are two extreme positions of the vehicle-mounted display terminal adjustment device 1 .

[0109] In some embodiments of the present invention, Figure 7 As shown, a first meshing tooth 622 is provided at one end of the first limiting frame 620 close to the first limiting protrusion 621, and a second meshing tooth 632 is provided at one end of the second limiting frame 630 close to the second limiting protrusion 631. The first meshing tooth 622 and the second meshing tooth 632 are meshed to improve the stability of the movement of the first limiting frame 620 and the second limiting frame 630.

[0110] According to some specific embodiments of the present invention, Figure 7 As shown, the limiting bracket 610 is provided with a sealing plate 640, a fixing plate 650 and a positioning plate 660 which are arranged in sequence at intervals, the first limiting bracket 620 and the second limiting bracket 630 are located between the fixing plate 650 and the positioning plate 660, and a rotating groove 150 for mounting and accommodating the driving mechanism 400 and the limiting mechanism 600 is formed between the main bracket 130 and the auxiliary bracket 140, and the sealing plate 640 covers the end of the rotating groove 150.

[0111] For example, the rotation groove 150 may include a first rotation groove 150 and a second rotation groove 150, the first rotation groove 150 may be formed between the first auxiliary bracket 141 and the main bracket 130, two limit brackets 610 may be provided between the first auxiliary bracket 141 and the main bracket 130, and the sealing plates 640 of the two limit brackets 610 cover both ends of the first rotation groove 150. The second rotation groove 150 may be formed between the second auxiliary bracket 142 and the main bracket 130, two limit brackets 610 may be provided between the second auxiliary bracket 142 and the main bracket 130, and the sealing plates 640 of the two limit brackets 610 cover both ends of the second rotation groove 150.

[0112] Furthermore, the outer surface of the sealing plate 640 facing away from the fixing plate 650, the side surface of the auxiliary bracket 140 in the first direction, and the side surface of the main bracket 130 in the first direction are located in the same plane. When the limiting bracket 610 is located in the rotation groove 150, the surface of the limiting bracket 610 can be flush with the first surface 110, which can avoid interfering with the arrangement of the external main flexible screen 200 and can effectively support the external main flexible screen 200.

[0113] According to some specific embodiments of the present invention, Figure 4 and Figure 5 As shown, the vehicle-mounted display terminal adjustment device 1 further includes a rotating housing 700, and the first surface 110 of the supporting bracket 100 is configured with a rotating groove 150, the rotating groove 150 is located between the main bracket 130 and the auxiliary bracket 140 and extends along the flip axis of the auxiliary bracket 140, and the rotating housing 700 and the groove bottom of the rotating groove 150 are configured to be mutually adapted arcs. When the auxiliary bracket 140 is unfolded relative to the main bracket 130, the rotating housing 700 is located in the rotating groove 150; when the auxiliary bracket 140 is folded relative to the main bracket 130, the rotating housing 700 covers the gap between the auxiliary bracket 140 and the main bracket 130.

[0114] For example, the rotating shell 700 can be fixedly connected to the driving mechanism 400 and the limiting mechanism 600 to fix the relative positions of the rotating shell 700, the auxiliary bracket 140 and the main bracket 130. When the auxiliary bracket 140 is unfolded relative to the main bracket 130, the surface of the driving mechanism 400, the surface of the limiting mechanism 600 and the first surface 110 are located in the same plane, which not only avoids interfering with the arrangement of the external main flexible screen 200, but also can effectively support the external main flexible screen 200. When the auxiliary bracket 140 is folded relative to the main bracket 130, the rotating shell 700 can shield the driving mechanism 400 and the limiting mechanism 600, avoid collision and interference with the driving mechanism 400 and the limiting mechanism 600, and ensure the smoothness of the flipping of the vehicle-mounted display terminal adjustment device 1.
