[0002] With the increasing intelligence of automobiles, it has become a trend to install a vehicle screen. The appearance of the vehicle screen can meet people's demand for information and entertainment, provide integration and convenience, and assist vehicle control and display important information. The vehicle screen is configured with a rotating mechanism to adapt to different viewing angles and line of sight requirements, provide optimal viewing effect and operation convenience.

[0104] REFERENCE Figures 1 to 3A movement mechanism includes a base 100, a first transmission rod 200, a second transmission rod 300, a first driving mechanism, and a second driving mechanism. The first transmission rod 200 is rotatably connected to the base 100 about a first rotation axis L1. The second transmission rod 300 movably penetrates the first transmission rod 200 along the first rotation axis L1, and the second transmission rod 300 can rotate with the first transmission rod 200. A first end of the second transmission rod 300 is used to connect a to-be-moved member, so that the to-be-moved member can move away from or close to the base 100. In the embodiment, the to-be-moved member is a display screen 800. The first driving mechanism is used to drive the first transmission rod 200 and the second transmission rod 300 to rotate about the first rotation axis L1. The second driving mechanism is used to drive the second transmission rod 300 to translate along the first rotation axis L1. In the application, through the first transmission rod 200 and the second transmission rod 300, two-dimensional movement is realized, and rotation and translation are realized respectively. The second transmission rod 300 moves in the axial direction, so that the second transmission rod 300 can drive the display screen 800 to move away from or close to the base 100, and thus the base 100 can be arranged in the height direction of the to-be-moved member, thereby reducing the thickness size of the display screen 800. The first transmission rod 200 and the second transmission rod 300 are arranged in a nested manner, so that the second transmission rod 300 can rotate with the first transmission rod 200. Through the integrated arrangement of the nested structure, the overall space occupation can be reduced, and the limited space resource can be effectively utilized. In the application, two independent driving mechanisms are controlled, and each driving mechanism can be controlled independently without mutual interference or conflict in operation, and thus the movement range of the device can be expanded.

[0105] In some embodiments of the application, the base 100 is provided with a receiving cavity 110, and the first driving mechanism and the second driving mechanism are arranged in the receiving cavity 110. Specifically, the receiving cavity 110 is formed in the inside of the base 100. The first transmission rod 200 is rotatably connected to the base 100, a first end of the first transmission rod 200 extends into the receiving cavity 110, and a second end of the first transmission rod 200 extends out of the base 100. The second transmission rod 300 is movably sleeved to the first transmission rod 200 along the axial direction of the second transmission rod 300, a first end of the second transmission rod 300 extends into the receiving cavity 110, and a second end of the second transmission rod 300 extends out of the first transmission rod 200. The second end of the second transmission rod 300 is used to connect the display screen 800.

[0106] In some embodiments of the application, the base 100 is provided with a connecting hole extending along the first rotation axis L1, and the first transmission rod 200 is inserted into the connecting hole. The first transmission rod 200 is provided with a limiting portion, and a radial dimension of the limiting portion is greater than a radial dimension of the connecting hole.

[0107] In some embodiments, the limiting part is a boss 210, which is used to clamp the first transmission rod 200 in the base 100. It can be understood that the radial dimension of the boss 210 is greater than the radial dimension of the first transmission rod 200. As shown in Figure 3 the boss 210 is arranged at the portion of the first transmission rod 200 in the accommodating cavity 110. The arrangement of the boss 210 constitutes the limiting of the first transmission rod 200 relative to the base 100 along the direction of the first rotation axis L1, so that the first transmission rod 200 can only rotate around the first rotation axis L1 in the base 100.

[0108] On the basis of the above-mentioned embodiments, the motion mechanism includes a turntable bearing 220. The first transmission rod 200 is connected with the base 100 through the turntable bearing 220. The turntable bearing 220 includes a first bearing part and a second bearing part which are perpendicular to each other. The first bearing part is arranged in the connecting hole and extends along the axial direction of the first rotation axis L1. The inner ring of the first bearing part is connected with the first transmission rod 200, and the outer ring is connected with the base 100. The first transmission rod 200 passes through the first bearing part. The second bearing part extends along the radial direction of the first rotation axis L1. The second bearing part is arranged between the boss 210 and the base 100 and is connected with the boss 210 and the base 100, respectively. The turntable bearing 220 can support the connection between the first transmission rod 200 and the base 100 and provide bearing support when rotating, so that the first transmission rod 200 can rotate smoothly on the base 100. The turntable bearing 220 in this embodiment is a T-shaped bearing. The upper end face and the inner ring of this kind of bearing have needle bearings, which can simultaneously complete the functions of an end face bearing and a needle or ball bearing, that is, when the first transmission rod 200 rotates, the radial and axial friction forces can be reduced at the same time.

[0109] In still some embodiments, the first transmission rod 200 is connected with the base 100 through two bearings. One of the bearings is arranged in the connecting hole. The other bearing is arranged between the boss 210 and the base 100. The two bearings provide bearing support when the first transmission rod 200 rotates relative to the base.

[0110] Referring to Figure 8 and Figure 9 , the motion mechanism performs left-right deflection. In this application, the left-right deflection of the motion mechanism is achieved by the first driving mechanism:

[0111] In some embodiments of the present application, the first driving mechanism includes a first motor 600, which is arranged in the accommodating cavity 110. The motor shaft of the first motor 600 is in transmission connection with the first transmission rod 200, so that the first transmission rod 200 can rotate relative to the base 100 with the rotation of the motor shaft of the first motor 600. Through the transmission connection between the motor shaft of the first motor 600 and the first transmission rod 200, power transmission is realized. When the motor shaft of the first motor 600 rotates, the first transmission rod 200 also rotates. In this way, the first transmission rod 200 can obtain sufficient power and torque through the first driving mechanism, and precise rotation control is realized. The first motor 600 is arranged in the accommodating cavity 110, so that the structure of the entire system is more compact.

[0112] On the basis of the above-mentioned embodiments, the first end of the first transmission rod 200 is provided with a first turbine 610. The first driving mechanism further includes a first gear 620 and a first worm 630. The first gear 620 is arranged at the end of the motor shaft of the first motor 600. The first worm 630 is in engagement with the first turbine 610, and the end of the first worm 630 is provided with a second gear 640, which is in engagement with the first gear 620. Since the engagement transmission is adopted, the torque transmission is stable, the transmission efficiency is high, and the transmission ratio is adjustable. Through adjusting the engagement transmission ratio, precise adjustment of the rotation angle and speed of the first transmission rod 200 can be realized.

[0113] The above-mentioned embodiments are only one preferred implementation mode of realizing the rotation of the first transmission rod 200. The rotation driving of the first transmission rod 200 can also be realized through bevel gear transmission, chain wheel transmission, etc.

[0114] Referring to Figure 7 With Figure 8 , the movement mechanism is translated up and down. In the present application, the translation of the movement mechanism is realized through a second driving mechanism:

[0115] In some embodiments of the present application, the second driving mechanism includes a second motor 700, which is arranged in the accommodating cavity 110. The motor shaft of the second motor 700 is in transmission connection with the second transmission rod 300, so that the second transmission rod 300 can translate relative to the base 100 with the rotation of the motor shaft of the second motor 700. Through the transmission connection between the motor shaft of the second motor 700 and the second transmission rod 300, power transmission is realized. When the motor shaft of the second motor 700 rotates, the second transmission rod 300 also translates. In this way, the second transmission rod 300 can obtain sufficient power through the second driving mechanism, and precise rotation control is realized. The second motor 700 is arranged in the accommodating cavity 110, so that the structure of the entire system is more compact.

[0116] On the basis of the above-mentioned embodiments, the first end of the second transmission rod 300 is provided with a rack or a screw rod or the like capable of linear movement. Preferably, the first end of the second transmission rod 300 is provided with a rack 710 structure. The second driving mechanism further comprises a third gear 720 and a fourth gear 730. The third gear 720 is arranged at the motor shaft end of the second motor 700. The fourth gear 730 is engaged with the rack 710, the central shaft of the fourth gear 730 extends towards the second motor 700, and the end of the central shaft of the fourth gear 730 is provided with a fifth gear 740, which is engaged with the third gear 720. Due to the use of meshing transmission, the torque transmission is stable, the transmission efficiency is high, the transmission ratio can be adjusted, and the rotary motion of the motor is converted into linear motion through the rack 710. When the motor rotates, the second transmission rod 300 will move linearly along its axial direction. The multi-stage meshing transmission can adjust the speed and torque, provide a larger range of force transmission and motion control, and thus can realize precise adjustment of the moving distance and speed of the second transmission rod 300.

[0117] The above-mentioned embodiments are only one preferred implementation for realizing the translation of the second transmission rod 300. The translation of the second transmission rod 300 can also be realized through a linear gear, or through the friction fit of a friction wheel clamped at both ends, so that the up-down movement is more stable.

[0118] In some embodiments of the present application, a first bearing 351 is arranged between the second transmission rod 300 and the first transmission rod 200. The first bearing 351 provides guidance and limiting when the second transmission rod 300 translates relative to the first transmission rod 200, so that the second transmission rod 300 and the first transmission rod 200 can relatively translate without rotating; at the same time, the contact area between the second transmission rod 300 and the first transmission rod 200 when the second transmission rod 300 translates can be reduced, the friction and energy loss can be reduced, and the transmission efficiency can be improved.

[0119] Referring to Figure 6 With Figure 7 , the movement mechanism rotates up and down. In the present application, the up-down rotation of the movement mechanism is realized through a third driving mechanism:

[0120] The third driving mechanism is used to drive the base 100 and the first transmission rod 200 to rotate together about a second rotation axis L2.

[0121] The movement mechanism further comprises a fixed assembly. The base 100 is rotatably connected to the fixed assembly along the second rotation axis L2, and the third driving mechanism is used to drive the base 100 to rotate about the second rotation axis L2 relative to the fixed assembly. The included angle between the second rotation axis L2 and the first rotation axis L1 is 60° to 120°. In some specific embodiments, the second rotation axis L2 is orthogonal to the first rotation axis L1.

[0122] The third driving mechanism is arranged at the end of the base 100. The fixing assembly includes a first fixing seat 510 and a second fixing seat 520, which are arranged opposite to each other. The base 100 is arranged between the first fixing seat 510 and the second fixing seat 520, and can rotate relative to the first fixing seat 510 and the second fixing seat 520 about the second rotation axis L2. The base 100 is rotatably mounted between the first fixing seat 510 and the second fixing seat 520. The first fixing seat 510 and the second fixing seat 520 provide stable support for the base 100, ensuring the stability and balance of the base 100, so that it can maintain a stable posture during rotation. In this application, the first fixing seat 510 and the second fixing seat 520 are used to fix to the fixing member on which the rotating display screen 800 is mounted. Alternatively, a connecting member is arranged in the first fixing seat 510 and / or the second fixing seat 520, one end of the connecting member is rotatably connected to the fixing seat, and the other end of the connecting member is connected to the base 100. The connecting member is connected to the fixing seat through a bearing. One end of the connecting member is in transmission connection with the motor shaft of the third motor 540, so as to rotate with the motor shaft of the third motor 540. Alternatively, the third motor 540 directly or indirectly drives the base 100 to rotate. Specifically, the output shaft of the third motor 540 can be directly connected to the base 100, and the rotation of the base 100 is realized by rotating the rotating shaft of the third motor 540 itself. This way is simple and direct, and the rotating torque of the third motor 540 is transmitted to the base 100, so that the base 100 rotates. The output shaft of the third motor 540 is connected to the base 100 through a transmission device (such as a gear, a belt, etc.), and the rotation torque and power of the third motor 540 are transmitted to drive the rotation of the base 100. This way can select appropriate transmission ratio and mode according to requirements to meet the requirements of rotation speed, torque, etc. The connection mode of the connecting member and the base 100 includes but is not limited to key connection and bolt connection, so that the base 100 can rotate with the connecting member.

[0123] In this embodiment, the first fixing seat 510, the base 100, and the second fixing seat 520 are sequentially connected to form a rod-like structure, so as to minimize the occupied space.

[0124] On the basis of the above-mentioned embodiments, the third motor 540 is arranged in the first fixed seat 510 or the second fixed seat 520. Alternatively, the shell of the third motor 540 is fixedly connected with the first fixed seat 510 or the second fixed seat 520. By integrating the third motor 540 with the first fixed seat 510 or the second fixed seat 520, the space can be effectively saved, the third motor 540 can also improve the rigid support of the first fixed seat 510 or the second fixed seat 520, and the structure and assembly process of the whole system can be simplified. For example, the first fixed seat 510 has a cylindrical main body, the cylindrical main body forms an accommodation space for accommodating the third motor 540, and the shell of the third motor 540 is attached to and fixed to the inner side wall of the cylindrical main body. When the first fixed seat 510 is connected to the vehicle body or other external components, the fixed connection of the shell of the third motor 540 can provide additional support and rigidity, and can also prevent the third motor 540 from loosening or vibrating during operation.

[0125] In still other embodiments, the third driving mechanism is provided with a third fixed seat. The third fixed seat 530 is used to be fixed to a fixed part on which the rotating display screen 800 is mounted, or is used to be fixed to the first fixed seat 510 or the second fixed seat 520. For example, the third fixed seat 530 is fixedly mounted on the first fixed seat 510. The third fixed seat 520 is arranged at an angle with the first fixed seat 510. The motor shell of the third motor 540 is fixedly connected with the third fixed seat 530, and the motor shaft of the third motor 540 is drivingly connected with the base 100, so that the base 100 can rotate relative to the third fixed seat 530 with the rotation of the motor shaft of the third motor 540. Through the arrangement of the third fixed seat 530, the stable fixation of the rotating display screen 800 is realized, and loosening or shaking in a moving or vibrating environment is avoided. Through the rotation of the third motor 540, sufficient power and torque can be provided to drive the base 100 to rotate.

[0126] The present application controls through three independent driving mechanisms to complete the angular coverage of multi-directional motion forms. By integrating the third driving mechanism, the first driving mechanism and the second driving mechanism on the base 100, the overall size and volume of the device can be reduced, the space can be saved, and the installation is facilitated. At the same time, each driving mechanism can be controlled independently without interfering or conflicting with each other, and then can move in different dimensions at the same time, thereby expanding the motion range of the device.

[0127] In some embodiments of the present application, the base 100 is configured as a long strip structure with a receiving cavity 110. The receiving cavity 110 contains the first driving mechanism and the third driving mechanism. The end of the movement mechanism is provided with the third driving mechanism. The third driving mechanism drives the base 100 to rotate around the second rotation axis L2. The first driving mechanism, the second driving mechanism provided on the base 100, and the first transmission rod 200 and the rotating rod extending into the receiving cavity 110 rotate with the base 100 around the second rotation axis L2. The third driving mechanism directly drives the base 100 to rotate up and down, and at the same time, the first driving mechanism and the second driving mechanism are arranged in the rotating shaft, so that the compact structure increases the up-down translation and left-right deflection movement without significantly increasing the thickness of the display screen 800.

[0128] According to the above-mentioned embodiments, the first fixed seat 510 and the second fixed seat 520 can be mounted on the vehicle. Optionally, the first fixed seat 510 and / or the second fixed seat 520 is provided with a connecting piece, one end of the connecting piece is rotatably connected with the fixed seat, and the other end of the connecting piece is connected to the base 100. The connecting piece and the fixed seat are connected through a bearing. One end of the connecting piece is in transmission connection with the motor shaft of the third motor 540, so as to be able to rotate with the motor shaft of the third motor 540. The connection mode of the connecting piece and the base 100 includes but is not limited to key connection and bolt connection, so that the base 100 can rotate with the connecting piece.

[0129] The second aspect of the present application provides a display device, which comprises a screen assembly and the above-mentioned movement mechanism, and the movement mechanism is connected with the screen assembly.

[0130] According to the display device of the second aspect of the present application, the movement mechanism makes the screen assembly more flexible, convenient and comfortable during use, and improves the user experience and convenience.

[0131] In some embodiments of the present application, the screen assembly comprises a mounting shell and a display screen 800. The display screen 800 is movably connected with the mounting shell along the first rotation axis L1, that is, the degrees of freedom in other directions are limited except the direction along the first rotation axis L1, so that the first transmission rod 200 can drive the second transmission rod 300 to move in other directions. The first transmission rod 200 is fixedly connected with the mounting shell. The mounting shell and the display screen 800 can move with the first transmission rod 200. The display screen 800 is connected with the second transmission rod 300, so that the display screen 800 can move with the second transmission rod 300 along the first rotation axis L1. The mounting shell is rotatably connected with the base 100 around the first rotation axis L1.

[0132] On the basis of the above-mentioned embodiments, the mounting shell comprises a first mounting shell 121 and a second mounting shell 122.

[0133] The first mounting shell 121 is a hollow cylindrical structure with one open end, extending into the receiving cavity 110 and rotatably connected to the base 100. The first mounting shell 121 is sleeved around the first transmission rod 200, which is fixedly connected to it. The second transmission rod 300 extends outside the first mounting shell 121, which is rotatably connected to the base 100. The first mounting shell 121 houses the first transmission rod 200, serving as a rotational support between the first transmission rod 200 and the base 100, and simultaneously transmitting the rotational torque of the motion mechanism to the first transmission rod 200. The first shell provides smooth, undulating rotation in two dimensions, and its design allows it to match other components, enhancing the overall aesthetics of the device.

[0134] The second mounting shell 122 is disposed on the side of the first mounting shell 121 away from the base 100. The second mounting shell 122 is constructed as a plate-like or hollow cuboid shell structure. As mentioned above, the first transmission rod 200 is sleeved inside the first mounting shell 121, and the second transmission rod 300 is sleeved inside the first transmission rod 200. In this embodiment, the second transmission rod 300 passes through the first mounting shell 121 and extends into the second mounting shell 122. The end face of the second mounting shell 122 away from the second transmission rod 300 (i.e., the end face facing the display screen 800) is provided with a first sliding groove 131 extending in the axial direction along the first rotation axis L1. The first sliding groove 131 is used to mount the display screen 800, and the second transmission rod 300 is used to drive the display screen 800 to move along the first sliding groove 131, such as... Figure 5 As shown, the display screen 800 is equipped with a slider 810, which is disposed within the first slide groove 131. The slider 810 fits tightly with the first slide groove 131, allowing the slider 810 to move smoothly within the first slide groove 131 while maintaining high precision and stability. Optionally, the cross-sectional shape of the first slide groove 131 is similar to a dovetail, with its opening size smaller than the bottom size. The dovetail shape allows the slider 810 and the first slide groove 131 to support each other, ensuring that the slider 810 will not detach from the first slide groove 131 or shift during movement.

[0135] On the basis of the above-mentioned embodiments, the second transmission rod 300 and the first mounting shell 121 are provided with a second bearing 352. The second bearing 352 provides guidance and limiting when the second transmission rod 300 translates relative to the first mounting shell 121, so that the second transmission rod 300 can translate relative to the first mounting shell 121 without rotating; at the same time, it can reduce the contact area between the second transmission rod 300 and the first mounting shell 121 when the second transmission rod 300 translates, reduce friction and energy loss, and improve transmission efficiency. As previously described, the second transmission rod 300 and the first transmission rod 200 are provided with a first bearing 351. Through the setting of the first bearing 351 and the second bearing 352, the radial distance between the second transmission rod 300 and the first transmission rod 200 is consistent up and down.

[0136] The first transmission rod 200 is connected to the base 100 through the turntable bearing 220. The first mounting shell 121 is sleeved on the first transmission rod 200, and the first mounting shell 121 extends into the connecting hole. The inner ring of the first bearing part of the turntable bearing 220 is connected with the first mounting shell 121, and the outer ring is connected with the base 100. The upper ring of the second bearing part is connected with the boss 210, and the lower ring is connected with the base 100. That is, the first mounting shell 121 is nested below the boss 210, and preferably, the upper end surface of the first mounting shell 121 abuts against the lower end surface of the boss 210. Thus, the connection between the first transmission rod 200, the first mounting shell 121 and the turntable bearing 220 is substantially gapless. Through the connection of the inner ring with the first mounting shell 121 and the outer ring with the base 100, and the connection of the upper ring with the boss 210 and the lower ring with the base 100, the stable connection between the turntable bearing 220 and the related parts is ensured, which can provide reliable support and transmit rotating force to ensure the normal operation of the equipment.

[0137] As shown in Figure 4 In some embodiments of the present application, the second driving mechanism includes at least three groups of first connecting rods 310 and second connecting rods 320 which are cross arranged and rotationally connected with each other. Among them, the first group of first connecting rods 310 and second connecting rods 320 are hingedly connected to the second end of the second transmission rod 300 through the first hinge point 331; the second group of first connecting rods 310 and second connecting rods 320 are hingedly connected to the base 100, preferably to the second mounting shell 122, through the second hinge point 332; the third group of first connecting rods 310 and second connecting rods 320 are hingedly connected to the display screen 800 through the third hinge point 333. Preferably, two first connecting rods 310 and two second connecting rods 320 are arranged between the first hinge point 331 and the second hinge point 332, and the two first connecting rods 310 are parallel to each other, and the two second connecting rods 320 are parallel to each other. A plurality of first connecting rods 310 and a plurality of second connecting rods 320 are arranged between the second hinge point 332 and the third hinge point 333, and the plurality of first connecting rods 310 are parallel to each other, and the plurality of second connecting rods 320 are parallel to each other.

[0138] On the basis of the above-mentioned embodiments, the length of the first connecting rod 310 and the second connecting rod 320 between the first hinge point 331 and the second hinge point 332 is less than the length of the first connecting rod 310 and the second connecting rod 320 between the second hinge point 332 and the third hinge point 333. The above-mentioned connecting rod structure can be decomposed into a plurality of similar and congruent triangles, so when the first hinge point 331 is driven up and down by the second transmission rod 300, the displacement is gradually amplified and finally transmitted to the third hinge point 333, and the third hinge point 333 is connected with the display screen 800, thereby driving the display screen 800 to move up and down. The displacement amplification effect of the connecting rod mechanism makes the second transmission rod 300 only need to move up and down a small stroke to drive the display screen 800 to complete a large stroke displacement, so it will not occupy the rotation space of the base 100. When the base 100 rotates up and down, the radial force of the second transmission rod 300 and the connecting rod mechanism is borne by the first mounting shell 121 and the second mounting shell 122, so the connecting rod mechanism can be thinned in the radial thickness direction, so that the overall up and down movement mechanism will not significantly increase the thickness of the display screen 800 area.

[0139] On the basis of the above-mentioned embodiments, the second mounting shell 122 is provided with a second sliding groove 132, and the third hinge point 333 is provided with a sliding rod 340, the sliding rod 340 and the second sliding groove 132 are in sliding connection, and the sliding rod 340 is connected to the display screen 800. It can be understood that the sliding rod 340 can extend from one end face to the other end face of the second mounting shell 122 through the second sliding groove 132, so that when the sliding rod 340 slides along the second sliding groove 132, the display screen 800 can be driven to slide along the first sliding groove 131.

[0140] According to the display device provided by the application, the display screen 800 can be rotated and adjusted to a suitable position by the movement mechanism, and the space in the vehicle can be saved. The three movement mechanisms are arranged around the base 100 in a compact structure, which ensures the structural strength, avoids occupying too much space, and improves the utilization rate of the space in the vehicle. Through the movement mechanism, the screen assembly is more flexible, convenient and comfortable during use, and the user's use experience and convenience are improved.

[0141] The application also provides a vehicle comprising the above-mentioned display device. The visual experience, comfort and convenience of the driver and passengers are improved.
