DETAILED DESCRIPTION

[0035] 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.

[0037] In the description of the present invention, "plurality" means two or more.

[0038] The following describes a posture adjustment assembly 1 for an audio-visual device according to an embodiment of the present invention with reference to the accompanying drawings.

[0039] like Figure 1-Figure 4 As shown, the posture adjustment assembly 1 includes a moving mechanism 100 and a rotating mechanism 200 .

[0040] The rotating mechanism 200 and the moving mechanism 100 are connected in transmission and linked to each other. One of the rotating mechanism 200 and the moving mechanism 100 is suitable for connecting to the audio-visual device 2. The audio-visual device 2 is rotated by the rotating mechanism 200 and linearly moved by the moving mechanism 100.

[0041] It should be noted that the audio-visual device 2 refers to a device that transmits information to a user through at least one of sound and image, such as a display screen, a speaker, a sound system, etc. The following description of the present application takes the audio-visual device 2 as an example of a display screen.

[0042] For example, the start, stop and direction of the posture adjustment component 1 can be controlled by buttons, voice, gestures and other signals.

[0043] According to the posture adjustment component 1 of the embodiment of the present invention, by connecting the rotating mechanism 200 and the moving mechanism 100 by transmission and linking them to each other, one of the rotating mechanism 200 and the moving mechanism 100 is suitable for connecting with the audio-visual device 2, and the audio-visual device 2 is driven to rotate by the rotating mechanism 200 and is driven to move linearly by the moving mechanism 100, wherein the moving mechanism 100 can drive the audio-visual device 2 to move in the up and down directions, and the rotating mechanism 200 can drive the audio-visual device 2 to rotate along the circumference of the audio-visual device 2 and the rotation angle range may not exceed 90°.

[0044] When the audio-visual device 2 is a display screen, the display screen can be placed in two ways: horizontal and vertical. When the display screen is in the horizontal state, the length direction is perpendicular to the up and down direction, and when the display screen is in the vertical state, the length direction is perpendicular to the horizontal direction. In this way, when the display screen is in the horizontal state, it will not block the driver's vision, and it is also convenient for passengers to watch programs that need to be watched in the horizontal screen, and to operate operations that need to be performed in the horizontal screen; when the display screen is in the vertical state, it is convenient for passengers to watch programs that need to be watched in the vertical screen, and to operate operations that need to be performed in the vertical screen. In addition, when actually riding, it is possible that the display screen is in a position between the horizontal state and the vertical state to facilitate viewing by passengers and the driver. By switching the display screen between the horizontal state and the vertical state, the best use position and viewing angle can be achieved.

[0045] Specifically, when the display screen is rotated from a horizontal state to a vertical state, the moving mechanism 100 drives the display screen to move upward to prevent the size of the display screen from increasing in the vertical direction and interfering with the installation position; when the display screen is rotated from a vertical state to a horizontal state, the moving mechanism 100 drives the display screen to move downward to make the display screen fit the installation position, thereby improving space utilization. In addition, the moving mechanism 100 and the rotating mechanism 200 drive the display screen to move at the same time, which can improve the reliability of the movement, and only one driving mechanism is provided to drive the moving mechanism 100 and the rotating mechanism 200 at the same time, and there is no need to separately provide driving mechanisms for the moving mechanism 100 and the rotating mechanism 200. The structure of the posture adjustment component 1 is more compact, which can save assembly space and improve transmission efficiency and transmission accuracy.

[0046] Thus, the posture adjustment assembly 1 according to the embodiment of the present invention is not only capable of performing a compound motion of rotation and linear movement, but also has the advantages of compact structure, small required assembly space, high transmission efficiency and transmission precision, etc.

[0047] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the moving mechanism 100 is suitable for connecting with the audio-visual device 2, and the rotating mechanism 200 drives the moving mechanism 100 to drive the audio-visual device 2 to rotate through the moving mechanism 100, and at the same time drives the moving mechanism 100 to drive the audio-visual device 2 to move linearly. In this way, the movement complexity of the linear movement is low, the moving mechanism 100 can be connected with the audio-visual device 2, the movement stability of the audio-visual device 2 can be ensured, and the connection is convenient.

[0048] According to some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the moving mechanism 100 includes a driving gear 110 , a steering gear 120 , a first rack 130 , a second rack 140 and a fixed bracket 150 .

[0049] The driving gear 110 is connected to the rotating mechanism 200 and is suitable for being connected to the audio-visual device 2. For example, the audio-visual device 2 is mounted on the driving gear 110 by screws or other threaded fasteners, and the driving gear 110 is mounted on the rotating mechanism 200 by screws or other threaded fasteners. The rotating mechanism 200 is suitable for driving the audio-visual device 2 to rotate through the driving gear 110, the steering gear 120 is meshed with the driving gear 110, the first rack 130 and the second rack 140 are respectively arranged on both sides of the radial direction of the driving gear 110, the first rack 130 is transmission-connected to the steering gear 120, the second rack 140 is transmission-connected to the driving gear 110, and the first rack 130 and the second rack 140 are mounted on the fixed bracket 150.

[0050] For example, the fixing bracket 150 may be fixedly connected to the vehicle body, and the first rack 130 and the second rack 140 may be mounted on the fixing bracket 150 by screws or other threaded fasteners. The teeth of the first rack 130 are located on the side of the first rack 130 facing the second rack 140, and the teeth of the second rack 140 are located on the side of the second rack 140 facing the first rack 130. The driving gear 110 and the steering gear 120 may be located between the first rack 130 and the second rack 140.

[0051] By providing the driving gear 110, the driving gear 110 can be rotated synchronously with the rotating mechanism 200 to drive the display screen to rotate, and when the driving gear 110 rotates, the driving gear 110 is connected to the second rack 140 through transmission, so that the driving gear 110 can be linearly moved along the length direction of the second rack 140, thereby driving the display screen to move linearly, so that the display screen can move linearly while rotating, that is, the composite movement of rotation and linear movement of the audio-visual device 2 can be achieved through one driving structure.

[0052] In addition, a steering gear 120 is provided, and the steering gear 120 is respectively connected to the driving gear 110 and the first rack 130 in transmission, so that the steering gear 120 can change the direction of the linear movement of the driving gear 110 relative to the first rack 130, so that the driving gear 110 moves in the same direction relative to the first rack 130 and the second rack 140. In this way, the linear movement of the driving gear 110 is limited at the radially opposite ends of the driving gear 110, which can improve the stability of the linear movement of the driving gear 110.

[0053] In addition, a fixed bracket 150 is provided to fix the relative position of the first rack 130 and the second rack 140, for example, the first rack 130 and the second rack 140 are parallel, thereby ensuring the reliability of the relative position of the first rack 130 and the second rack 140, and further improving the stability of the linear movement of the driving gear 110 to avoid shaking during the linear movement of the display screen.

[0054] Alternatively, if Figure 3 and Figure 4 As shown, the fixing bracket 150 and the rotating mechanism 200 are located on a side of the driving gear 110 that faces away from the audio-visual device 2 .

[0055] Since the audio-visual device 2 needs to be located in the same space as the user so that the audio and video of the audio-visual device 2 can be better transmitted to the user, in order to avoid the fixed bracket 150 and the rotating mechanism 200 being exposed to the user's field of vision, the fixed bracket 150 and the rotating mechanism 200 are located on the side of the driving gear 110 that is away from the audio-visual device 2. This not only avoids the fixed bracket 150 and the rotating mechanism 200 from being exposed to the user's field of vision, which is convenient for the arrangement of the posture adjustment component 1, but also prevents the audio-visual device 2 from interfering with the fixed bracket 150 and the rotating mechanism 200 during rotation and linear movement, thereby increasing the displacement range of the audio-visual device 2.

[0056] Furthermore, if Figure 3 and Figure 4 As shown, the moving mechanism 100 further includes a first driven gear 131 and a second driven gear 141. The first driven gear 131 is meshed with the steering gear 120 and the first rack 130 respectively, the first driven gear 131 and the second driven gear 141 are arranged on both radial sides of the driving gear 110, and the second driven gear 141 is meshed with the driving gear 110 and the second rack 140 respectively.

[0057] By adjusting the gear ratio of the second driven gear 141 and the driving gear 110, as well as the gear ratio of the driving gear 110, the steering gear 120 and the first driven gear 131, the moving speed of the first driven gear 131 along the first rack 130 and the moving speed of the second driven gear 141 along the second rack 140 can be adjusted, thereby adjusting the speed of the linear movement of the display screen and the rotating mechanism 200 to prevent the display screen and the rotating mechanism 200 from shaking during the linear movement.

[0058] Furthermore, if Figure 3 and Figure 4 As shown, the moving mechanism 100 further includes a steering shaft 121 , a first fixed shaft 132 and a second fixed shaft 142 .

[0059] The steering shaft 121 is fixed to the rotating mechanism 200 , the steering gear 120 is rotatably sleeved on the steering shaft 121 , the first fixed shaft 132 and the second fixed shaft 142 are fixed to the rotating mechanism 200 , the first driven gear 131 is rotatably sleeved on the first fixed shaft 132 , and the second driven gear 141 is rotatably sleeved on the second fixed shaft 142 .

[0060] For example, the steering shaft 121, the first fixed shaft 132 and the second fixed shaft 142 are all threadedly connected to the rotating mechanism 200. Compared with the technical solution that the steering gear 120 and the steering shaft 121 are fixedly connected, the first driven gear 131 and the first fixed shaft 132 are fixedly connected, the second driven gear 141 is rotatably sleeved on the second fixed shaft 142 and fixedly connected, and then the steering shaft 121, the first fixed shaft 132 and the second fixed shaft 142 are rotatably installed on the rotating mechanism 200, the technical solution of the present invention can improve the connection reliability between the steering shaft 121, the first fixed shaft 132 and the second fixed shaft 142 and the rotating mechanism 200, thereby ensuring the rotation reliability of the steering gear 120, the first driven gear 131 and the second driven gear 141, so that the movement of the first driven gear and the second driven gear 141 along the first rack 130 and the second rack 140 is more reliable, and further the linear movement of the display screen and the rotating mechanism 200 is reliable.

[0061] Specifically, Figure 4 As shown, the fixing bracket 150 includes a main body 151 , a first folded edge 152 and a second folded edge 153 .

[0062] The first folded edge 152 and the second folded edge 153 are respectively bent from both ends of the main body 151 toward one side of the driving gear 110, the first rack 130 is connected to the side of the first folded edge 152 facing the second folded edge 153, and the second rack 140 is connected to the side of the second folded edge 153 facing the first folded edge 152.

[0063] For example, the first rack 130 and the second rack 140 can stop at the side of the main body 151 facing the driving gear 110, the first folded edge 152 and the first rack 130 can be connected by screws or other threaded fasteners, and the second folded edge 153 and the second rack 140 can be connected by screws or other threaded fasteners.

[0064] In this way, the fixed bracket 150 can form a semi-enclosed structure for the first rack 130 and the second rack 140, thereby improving the reliability of the relative position of the first rack 130 and the second rack 140 and the fixed bracket 150, and avoiding the first rack 130 and the second rack 140 from deflecting relative to the fixed bracket 150, so that the rotating mechanism 200 and the display screen can move stably.

[0065] According to some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the rotating mechanism 200 includes a housing 210 , a driving motor (not shown in the figure), a rotating disk 230 and a mounting bracket 240 .

[0066] The shell 210 is provided with a first rotation limit portion, the driving motor is installed on the shell 210, the rotating disk 230 is transmission-connected to the driving motor and is provided with a second rotation limit portion, the first rotation limit portion and the second rotation limit portion cooperate to limit the rotation position of the audio-visual device 2, and the mounting bracket 240 is respectively connected to the rotating disk 230 and the moving mechanism 100.

[0067] For example, the drive motor can be installed in the housing 210, and a part of the rotating disk 230 extends into the housing 210, so that the position of the transmission connection between the rotating disk 230 and the drive motor is blocked by the housing 210, thereby ensuring the reliability of the transmission connection between the rotating disk 230 and the drive motor. In addition, the cooperation of the first rotation limiter and the second rotation limiter can, on the one hand, limit the extreme rotation angle of the rotating disk 230 relative to the housing 210, thereby limiting the extreme rotation angle of the display screen, so as to prevent the display screen from excessively rotating and affecting the viewing experience or interfering with other structures, and also improve the accuracy of the rotation stroke of the display screen; on the other hand, since the moving mechanism 100 drives the linear movement of the display screen and the rotating mechanism 200 drives the rotation movement of the display screen to start and stop synchronously, when the display screen is prevented from continuing to rotate under the cooperation of the first rotation limiter and the second rotation limiter, the display screen is also prevented from continuing to move linearly, thereby limiting the linear stroke of the display screen, so as to improve the accuracy of the moving stroke of the display screen and the accuracy of the stop position.

[0068] It should be noted that the method of determining whether the rotation and linear movement of the audio-visual device 2 are in place includes but is not limited to using a displacement sensor, a current of a driving motor, and the like.

[0069] Alternatively, if Figure 3 and Figure 4 As shown, the moving mechanism 100 is connected to the end surface of the mounting bracket 240, and the outer periphery of the mounting bracket 240 is connected to the outer periphery of the rotating disk 230. For example, the driving gear 110 is mounted on the mounting bracket 240 by screws or other threaded fasteners, and the steering shaft 121, the first fixed shaft 132 and the second fixed shaft 142 are all connected to the mounting bracket 240.

[0070] Since the axial dimension of the rotating disk 230 is relatively large, the difficulty of disassembling and assembling between the mounting bracket 240 and the rotating disk 230 can be reduced by connecting the outer circumference of the mounting bracket 240 to the outer circumference of the rotating disk 230. The axial dimension of the driving gear 110 is relatively small, which is convenient for direct connection to the end face of the mounting bracket 240, simplifying the disassembly and assembly steps.

[0071] Furthermore, if Figure 3 and Figure 4 As shown, the outer circumference of the mounting bracket 240 is provided with a plurality of positioning blocks 241 and a plurality of claws 242 which are alternately arranged along its circumference, and the outer circumference of the rotating disk 230 is provided with a plurality of positioning grooves 231 and a plurality of notches 232 which are alternately arranged along its circumference, the plurality of positioning blocks 241 are inserted into the plurality of positioning grooves 231 one by one, and the plurality of claws 242 are inserted into the plurality of notches 232 one by one and are clamped to the rotating disk 230.

[0072] In this way, not only the relative positions of the mounting bracket 240 and the rotating disk 230 in the circumferential direction of the rotating disk 230 are fixed, but also the relative positions of the mounting bracket 240 and the rotating disk 230 in the axial direction of the rotating disk 230 are fixed, thereby ensuring the reliability of the relative position between the mounting bracket 240 and the rotating disk 230, and also facilitating reducing the overall volume of the mounting bracket 240 and the rotating disk 230.

[0073] Furthermore, if Figure 3 and Figure 4 As shown, the outer peripheral edge of the rotating disk 230 is provided with a plurality of mounting ears 233 arranged at intervals along its circumference, and the plurality of mounting ears 233 correspond one-to-one to the plurality of positioning blocks 241. Each mounting ear 233 is located on the outer side of the corresponding positioning block 241 and is connected to the corresponding positioning block 241 by a threaded fastener passing through the mounting ear 233.

[0074] In other words, the positioning block 241 is surrounded by the groove wall of the corresponding positioning groove 231 and the corresponding mounting ear 233, and the positioning block 241 and the mounting ear 233 are fixed by a threaded fastener. In this way, the connection strength between the rotating disk 230 and the mounting bracket 240 is further improved, and the reliability of the synchronous rotation between the rotating disk 230 and the mounting bracket 240 can be ensured.

[0075] According to some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the rotating mechanism 200 also includes at least one stage of a worm gear reduction assembly (not shown in the figure), an output gear 250 and a locking ring 260 .

[0076] The worm gear reduction assembly is installed on the housing 210 and the input end is transmission-connected to the drive motor, the output gear 250 is transmission-connected to the output end of the worm gear reduction assembly, the end surface of the output gear 250 facing the rotating disk 230 is provided with a plurality of fixing grooves arranged at intervals along the circumference of the output gear 250, the locking ring 260 is provided with a plurality of fixing protrusions, and the plurality of fixing protrusions are inserted into the plurality of fixing grooves one by one, a portion of the rotating disk 230 is inserted into the locking ring 260 and the output gear 250 and is fixed to the locking ring 260 in the circumferential direction of the locking ring 260.

[0077] Among them, a two-stage worm gear reduction assembly can be provided between the driving motor and the output gear 250, and the worm gear reduction assembly has the function of reducing speed and increasing torque, so that the rotation speed of the output gear 250 is less than the output rotation speed of the driving motor, and the torque of the output gear 250 is greater than the output torque of the driving motor, so as to ensure the stability of the output gear 250 driving the rotating disk 230 to rotate. In addition, the worm gear can realize the self-locking function to prevent the display screen from reversing in a non-human controlled state when the driving motor stops outputting driving force, so as to improve the reliability of the display screen stopping.

[0078] In addition, the locking ring 260 is used to fix the relative position between the output gear 250 and the rotating disk 230 in the circumferential direction of the rotating disk 230, that is, the locking ring 260, the output gear 250 and the rotating disk 230 rotate synchronously. In addition, a part of the rotating disk 230 is inserted into the locking ring 260 and the output gear 250, which can fix the relative position of the locking ring 260 and the output gear 250 in the radial direction of the rotating disk 230, and prevent the rotating disk 230 from deflecting relative to the locking ring 260 and the output gear 250, which can ensure that the position of the display screen during rotation is more reliable.

[0079] According to some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the rotating mechanism 200 further includes a connecting bracket 270 , a first slider 280 and a second slider 290 .

[0080] The housing 210 is mounted on the connecting bracket 270, and the first slider 280 and the second slider 290 are respectively arranged at both ends of the connecting bracket 270, for example, the first slider 280 and the second slider 290 are mounted on the connecting bracket 270 by screws or other threaded structures. The moving mechanism 100 includes a first rack 130 and a second rack 140, a first slide rail 133 is provided on the side of the first rack 130 facing the connecting bracket 270, and a second slide rail 143 is provided on the side of the second rack 140 facing the connecting bracket 270, the first slider 280 is slidably mounted on the first slide rail 133, and the second slider 290 is slidably mounted on the second slide rail 143.

[0081] For example, after the first slider 280 is installed on the first slide rail 133, it can only slide along the length direction of the first slide rail 133, and will not be relatively displaced in other directions with the first slide rail 133. After the second slider 290 is installed on the second slide rail 143, it can only slide along the length direction of the second slide rail 143, and will not be relatively displaced in other directions with the second slide rail 143.

[0082] When the driving gear 110 rotates, the first driven gear 131 will rotate relative to the first rack 130 and move along the length direction of the first rack 130, and the second driven gear 141 will rotate relative to the second rack 140 and move along the length direction of the second rack 140. The first driven gear 131 drives the rotating mechanism 200 to move along the length direction of the first rack 130 (i.e., the second rack 140) through the first fixed shaft 132 and the second driven gear 141 drives the rotating mechanism 200 through the second fixed shaft 142. At this time, the first slider 280 cooperates with the first slide rail 133 and the second slider 290 cooperates with the second slide rail 143, which can assist the movement of the rotating mechanism 200.

[0083] In this way, on the one hand, the connection strength between the rotating mechanism 200 and the first rack 130 and the second rack 140 is higher, and the first slider 280 and the second slider 290 can provide movement guides for the rotating mechanism 200 on the opposite sides of the rotating mechanism 200, which is beneficial to improving the movement stability of the rotating mechanism 200. On the other hand, the cooperation between the first slider 280 and the first slide rail 133 and the cooperation between the second slider 290 and the second slide rail 143 can share the pressure on the steering shaft 121, the first fixed shaft 132 and the second fixed shaft 142 due to the gravity of the rotating mechanism 200, thereby reducing the probability of breaking of the steering shaft 121, the first fixed shaft 132 and the second fixed shaft 142, and extending the service life of the posture adjustment component 1.

[0084] The following is an example of describing the process of adjusting the display screen from the horizontal state to the vertical state by the posture adjustment component 1 with reference to the accompanying drawings:

[0085] First, the driving force output by the driving motor is transmitted to the output gear 250 after being decelerated and torque-increased by the worm gear assembly, so as to drive the output gear 250 to rotate in the forward direction;

[0086] Then, the output gear 250 drives the rotating disk 230 to rotate through the locking ring 260, thereby driving the mounting bracket 240 fixed to the rotating disk 230 and the driving gear 110 mounted on the mounting bracket 240 to rotate. At this time, the driving gear 110 drives the display screen to rotate, and the display screen gradually rotates from the horizontal state to the vertical state;

[0087] Next, the driving gear 110 drives the second driven gear 141 and the steering gear 120 to rotate, the steering gear 120 drives the first driven gear 131 to rotate, the first driven gear 131 moves upward along the first rack 130, the second driven gear 141 moves upward along the second rack 140, the rotating mechanism 200 is driven by the driving gear 110 to move upward, at this time the first slider 280 moves upward along the first slide rail 133, and the second slider 290 moves upward along the second slide rail 143;

[0088] Finally, when the display screen rotates to the vertical state, the second rotation limit portion of the rotating disk 230 abuts against the first rotation limit portion of the housing 210 to prevent the drive motor from continuing to rotate, and the drive motor is blocked and stops moving.

[0089] The process of adjusting the display screen from the vertical state to the horizontal state by the posture adjustment component 1 is described with reference to the accompanying drawings as an example:

[0090] First, the driving force output by the driving motor is transmitted to the output gear 250 after being decelerated and torque-increased by the worm gear assembly, so as to drive the output gear 250 to rotate in the reverse direction;

[0091] Then, the output gear 250 drives the rotating disk 230 to rotate through the locking ring 260, thereby driving the mounting bracket 240 fixed to the rotating disk 230 and the driving gear 110 mounted on the mounting bracket 240 to rotate. At this time, the driving gear 110 drives the display screen to rotate, and the display screen gradually rotates from the vertical state to the horizontal state;

[0092] Next, the driving gear 110 drives the second driven gear 141 and the steering gear 120 to rotate, the steering gear 120 drives the first driven gear 131 to rotate, the first driven gear 131 moves downward along the first rack 130, the second driven gear 141 moves downward along the second rack 140, the rotating mechanism 200 is driven by the driving gear 110 to move downward, at this time, the first slider 280 moves downward along the first slide rail 133, and the second slider 290 moves downward along the second slide rail 143;

[0093] Finally, when the display screen rotates to the horizontal state, the second rotation limit portion of the rotating disk 230 abuts against the first rotation limit portion of the housing 210 to prevent the drive motor from continuing to rotate, and the drive motor is blocked and stops moving.
