DETAILED DESCRIPTION

[0049] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thoroughly and comprehensively understood.

[0050] The present application relates to a vehicle, which includes a display screen and a posture adjustment component, wherein a bracket of the posture adjustment component is installed in a cockpit, and the posture adjustment component is used to fix the display screen and drive the display screen to rotate. The display screen and the posture adjustment component can be arranged in a vehicle compartment (such as a center console), and the display screen is used to display time, date, vehicle information, vehicle environment information, and navigation information. In some embodiments, the display screen can also be used to display entertainment, communication and other information to enhance the user's driving experience.

[0051] Due to the different heights and driving styles of different users, or the different seats of the users using the display screen in the vehicle compartment (such as the driver's seat or the co-pilot's seat), the users have different viewing angle requirements for the display screen. The posture adjustment component of the present application is used to drive the display screen to rotate to meet the viewing needs of different users in different scenarios.

[0052] See also Figure 1 and Figure 2 A posture adjustment assembly 100 is provided in one embodiment of the present application.

[0053] like Figure 1 and Figure 2 As shown, the posture adjustment assembly 100 provided in the present application includes a bracket 10, a transmission mechanism 30, a drive mechanism 20 and a sensor 50. The bracket 10 includes a receiving cavity 11, the transmission mechanism 30 is at least partially located in the receiving cavity 11, and the output end of the transmission mechanism 30 is suitable for connecting to a mounting seat 90, and the mounting seat 90 is suitable for connecting to a display screen.

[0054] Specifically, in one embodiment, Figure 1 As shown, the transmission mechanism 30 includes a worm 31, a worm wheel 32 and a transmission shaft 33. The worm 31 is the input end of the transmission mechanism 30. The worm wheel 32 is transmission-connected between the worm 31 and the transmission shaft 33. The transmission shaft 33 is the output end of the transmission mechanism 30. One end of the transmission shaft 33 is used to connect to the mounting seat 90 to drive the mounting seat 90 to rotate, and the other end is used to be transmission-connected to the worm wheel 32 in the transmission mechanism 30. The transmission mechanism 30 is used to transmit power to the mounting seat 90.

[0055] The posture adjustment component 100 of the present application includes a driving mechanism 20 , and an output end of the driving mechanism 20 is connected to an input end of a transmission mechanism 30 .

[0056] Specifically, in one embodiment, Figure 1 As shown, the transmission mechanism 30 includes a reduction mechanism 80 , the output end of the driving mechanism 20 is transmission-connected to the input end of the reduction mechanism 80 , and the output end of the reduction mechanism 80 is transmission-connected to the worm 31 , thereby transmitting power to the mounting seat 90 .

[0057] That is, the transmission mechanism 30 in the posture adjustment component 100 of the present application is transmission-connected between the driving mechanism 20 and the mounting seat 90, and the end of the transmission shaft 33 away from the driving mechanism 20 is used to drive the display screen to move. When the driving mechanism 20 is working, the motor in the driving mechanism 20 transmits power to the transmission mechanism 30, driving the transmission mechanism 30 to rotate, and the transmission mechanism 30 transmits power to the mounting seat 90 through the internal mechanism action. The mounting seat 90 is connected to the display screen, and the rotation of the mounting seat 90 will drive the display screen to rotate synchronously. That is, the posture adjustment component 100 of the present application can drive the display screen to rotate relative to the vehicle compartment to meet the viewing needs of different users in different scenarios.

[0058] The posture adjustment component 100 of the present application further includes a sensor 50, which is disposed in the accommodating cavity 11. The sensor 50 is used to sense at least one of the driving mechanism 20, at least a portion of the transmission mechanism 30, and the mounting seat 90 to detect the rotation angle of the display screen.

[0059] exist Figure 1 and Figure 2 In the illustrated embodiment, the sensor 50 is fixed in the accommodating cavity 11 of the bracket 10. The sensor 50 is used to detect the rotation angle of the transmission shaft 33. When the display screen is rotated to a preset position, the sensor 50 sends a signal to the driving mechanism 20. The driving mechanism 20 that receives the signal will stop working, and the mounting base 90 stops rotating, so that the display screen stops at the preset position.

[0060] When the display screen is not yet in the preset position and has met the user's viewing needs in the current scene, the sensor 50 can also send a signal to the drive mechanism 20 based on the position that meets the user's viewing needs in the current scene. The drive mechanism 20 that receives the signal will stop working and the mounting bracket 90 will stop rotating, so that the display screen stops at the position where the user needs to view the current scene.

[0061] In addition, in one embodiment, the posture adjustment component 100 may also be provided with a circuit board 40, which is used to receive and analyze the detection results of the sensor 50, and control the start and stop of the drive mechanism 20 according to the detection results. The circuit board 40 can connect multiple sensors 50 and perform comprehensive analysis, which is more accurate and convenient than the direct communication connection between the sensor 50 and the drive mechanism 20. Other programs can also be set in the circuit board 40 to realize the start and stop of the display screen at any time, so that the user can adjust the position of the display screen at will, which is conducive to improving the user experience.

[0062] It can be understood that the vehicle of the present application adopts the above-mentioned posture adjustment component 100, which can make the display screen rotate relative to the vehicle cabin and form a reliable high-precision limit for the display screen to avoid interference between the display screen and other components in the vehicle cabin. At the same time, because the posture adjustment component 100 adopts sensor limit, it has a longer service life compared to the posture adjustment component adopting mechanical limit.

[0063] The vehicle of the present application can also adjust the display screen to a position that is convenient for users to watch based on the needs of different users, providing a better display screen viewing experience to meet the user's viewing needs in the current scenario.

[0064] Therefore, the posture adjustment component 100 of the present application detects the rotation angle of the display screen through the sensor 50 and communicates with the drive mechanism 20 to limit the maximum rotation angle of the display screen relative to the vehicle cabin (i.e., the above-mentioned preset position). At the same time, when the display screen is located at any position that does not exceed its maximum rotation angle range, the sensor 50 can send a signal to the drive mechanism 20 to make the display screen stop at the current position to meet the user's viewing needs in the current scene.

[0065] The sensor 50 of the posture adjustment component 100 of the present application is arranged in the accommodating cavity 11 of the bracket 10. The sensor 50 is arranged in the accommodating cavity 11 without the need for punching, which facilitates the connection between the sensor 50 and the bracket 10. At the same time, the sensor 50 can be protected, and the external components are prevented from contacting the sensor 50, ensuring the normal operation of the sensor 50, and improving the reliability of the posture adjustment component 100. By limiting the rotation angle of the display screen, the display screen can be prevented from interfering with and colliding with other structures in the vehicle cabin during rotation, thereby ensuring the safety of the display screen during the use of the posture adjustment component 100. At the same time, the allowable rotation angle of the display screen is related to the rotation range of the transmission mechanism 30, the drive mechanism 20 and the mounting seat 90. By limiting the maximum rotation angle of the drive mechanism 20 or the transmission mechanism 30, and avoiding the drive mechanism 20 or the transmission mechanism 30 or the mounting seat 90 from interfering with and colliding with other structures in the vehicle cabin, the goal of limiting the rotation angle of the display screen can also be achieved.

[0066] It needs to be pointed out that Figure 1 and Figure 2In the illustrated embodiment, the sensor 50 is fixed to the bracket 10 to detect the rotation angle of the display screen. In other embodiments, the sensor 50 may be fixed to the bracket 10 to detect the rotation angle of the drive mechanism 20, the transmission mechanism 30, or the mounting seat 90. The drive mechanism 20 drives the transmission mechanism 30 and the mounting seat 90 to rotate, and then drives the display screen to rotate. Therefore, the rotation angles of the drive mechanism 20, the transmission mechanism 30, and the mounting seat 90 are related to the rotation angle of the display screen. By detecting the rotation angle of the drive mechanism 20, the transmission mechanism 30, or the mounting seat 90 through the sensor 50, the rotation angle of the display screen can also be detected.

[0067] On the other hand, the sensor 50 may also be fixed to the portion of the transmission mechanism 30 located in the accommodating chamber 11 , and the sensor 50 detects the rotation angle of the driving mechanism 20 or the transmission mechanism 30 or the mounting seat 90 .

[0068] The posture adjustment component 100 of the present application can be provided with multiple sensors 50, and the multiple sensors 50 can respectively detect the rotation angles of the drive mechanism 20, the transmission mechanism 30 and the mounting seat 90. Combining the detection results of multiple sensors 50 can obtain more accurate position data of the display screen. Compared with only setting the sensor 50 at the drive mechanism 20 or other single position, the error between the detection result of the sensor 50 in the posture adjustment component 100 of the present application and the actual position of the display screen is smaller, and thus the rotation angle of the display screen can be more accurately limited.

[0069] The posture adjustment component 100 of the present application can also allow the display screen to stop at any position within the maximum rotation angle range to meet the user's viewing needs in the current scene.

[0070] When the display screen is not in the preset position and is rotated to a position that meets the user's viewing needs in the current scene, the sensor 50 can send a signal to the drive mechanism 20. The drive mechanism 20 that receives the signal will stop working and the mounting bracket 90 will stop rotating, so that the display screen stays at the position that the user needs to view in the current scene.

[0071] In one embodiment, the bracket 10 includes a first partition 12, which is used to divide the accommodating chamber 11 into a first area 111 and a second area 112. At least part of the transmission mechanism 30 is located in the first area 111, the driving mechanism 20 is located in the second area 112, and the sensor 50 is located in the first area. The sensor 50 is used to sense the transmission mechanism 30.

[0072] In one embodiment, if Figure 1 and Figure 2As shown, the transmission mechanism 30 includes a worm 31 and a worm wheel 32, the worm 31 and part of the worm wheel 32 are both located in the first area 111, the driving mechanism 20 includes a motor, the housing of the motor is embedded in the bracket 10, and the reduction mechanism 80 is transmission-connected between the worm 31 and the output shaft of the motor. The sensor 50 is located in the first area 111 and is used to sense the rotation angle of the worm 31.

[0073] In another embodiment, the sensor 50 is located in the first area 111 and is used to sense the rotation angle of the worm gear 32 .

[0074] In another embodiment, the sensor 50 is located in the first area 111 , the transmission mechanism 30 includes a transmission shaft 33 , the transmission shaft 33 is fixedly connected to the worm gear 32 , and at least a portion of the transmission shaft 33 is located in the first area 111 , and the sensor 50 is used to sense the rotation angle of the transmission shaft 33 .

[0075] It can be understood that in the above embodiment, the rotation angle of the display screen can be obtained by sensing the rotation angle of at least one of the worm 31, the worm wheel 32 and the transmission shaft 33 through the sensor 50, and then the sensor 50 and the driving mechanism 20 cooperate with each other to control the rotation of the display screen.

[0076] In one embodiment, if Figure 1 As shown, the accommodating chamber 11 includes a first side wall 13 and a second side wall 14 connected to the first partition plate 12 , and the sensor 50 is located on any one of the first partition plate 12 , the first side wall 13 and the second side wall 14 .

[0077] It can be understood that in the above embodiment, the first side wall 13 is the receiving cavity 11. Figure 1 The left side wall shown in FIG. 1 is a side wall of the first side wall 13. However, in other embodiments, the first side wall 13 may also accommodate the cavity 11. Figure 1 The right side wall shown, i.e. the sensor 50, can also be located in the accommodating cavity 11 as shown in FIG. Figure 1 on the right side wall shown.

[0078] In one embodiment, the sensor 50 is partially attached to at least two of the first partition 12, the first side wall 13, and the second side wall 14. It can be understood that the sensor 50 is attached to at least two of the first partition 12, the first side wall 13, and the second side wall 14 so that the sensor 50 has a larger fixing area, thereby improving the reliability of the sensor 50.

[0079] In one embodiment, at least one of the first partition plate 12 , the first side wall 13 , and the second side wall 14 is provided with a notch, and the sensor 50 is placed in one of the notches.

[0080] In another embodiment, there is a notch on any two of the first partition 12, the first side wall 13, and the second side wall 14. For example, the first partition 12 is provided with a first notch on one side adjacent to the first side wall 13, and the first side wall 13 is provided with a second notch on one side adjacent to the first partition 12. The first notch and the second notch correspond to each other at least in part and together form a receiving groove. The sensor 50 is placed in the receiving groove formed by the combination of at least two notches. It is understandable that in other embodiments, the first notch may also be located on the first side wall 13 or the second side wall 14; the second notch may also be located on the first partition 12 or the second side wall 14.

[0081] It is understandable that placing the sensor 50 in the receiving groove formed by the notch or at least two notches can protect the sensor 50 and prevent the sensor 50 from directly contacting other components in the first area 111. At the same time, the sensor 50 can also have a larger fixing area, thereby improving the reliability of the sensor 50.

[0082] See also Figure 3-Figure 6 ,in, Figure 3 A schematic diagram of the exploded structure of a posture adjustment component 100 provided in another embodiment of the present application is illustrated; Figure 4 A structural schematic diagram of a posture adjustment component 100 provided in another embodiment of the present application from a viewing angle is shown; Figure 5 A structural schematic diagram of another perspective of a posture adjustment component 100 provided in another embodiment of the present application is illustrated; Figure 6 A structural schematic diagram of another perspective of the posture adjustment component 100 provided in another embodiment of the present application is illustrated.

[0083] In one embodiment, if Figure 3-Figure 6 As shown, the accommodating chamber 11 is divided into a first area 111 and a second area 112 by a first partition 12. Figure 1 and Figure 2 In the first partition 12 in the embodiment, the thickness of the first partition 12 is larger, the volume of the first area 111 is smaller, and the arrangement of the components of the transmission mechanism 30 is more compact. The distance between the sensor 50 fixed on the first partition 12, the first side wall 13 and the second side wall 14 and the components of the transmission mechanism 30 is closer, and it is easier to achieve the sensing of the sensor 50. In one embodiment, the sensor 50 in the posture adjustment component 100 includes an angle sensor, which is used to directly detect the rotation angle of the display screen. When the rotation angle of the display screen reaches the maximum rotation angle, the angle sensor sends a signal to the drive mechanism 20, and the drive mechanism 20 stops working.

[0084] In another embodiment, the sensor 50 in the posture adjustment assembly 100 includes a proximity sensor, which can be used to sense the display screen and detect the relative position of the two during the rotation of the display screen relative to the bracket 10. When the relative position between the display screen and the bracket 10 reaches a preset distance, the proximity sensor sends a signal to the driving mechanism 20, and the driving mechanism 20 stops working.

[0085] It is understandable that in some embodiments, the proximity sensor can also be used to sense the transmission mechanism 30 or the mounting base 90 , and the proximity sensor rotates with the transmission mechanism 30 or the mounting base 90 to detect the relative position of the display screen and the bracket 10 .

[0086] In some embodiments, the sensor 50 is disposed in the second area 112 for sensing the driving mechanism 20 .

[0087] In one embodiment, the bracket 10 includes a first partition 12, which is used to separate the accommodating chamber 11 into a first area 111 and a second area 112. At least part of the transmission mechanism 30 is located in the first area 111, the driving mechanism 20 is located in the second area 112, and the sensor 50 is located in the second area 112. The sensor 50 is used to sense the driving mechanism 20 and can also detect the relative position of the display screen and the bracket 10.

[0088] In one embodiment, the sensor 50 in the posture adjustment component 100 can be an encoder, which is arranged inside the motor in the drive mechanism 20. The encoder is used to detect the rotation angle or number of rotations of the motor rotor or motor shaft to detect the rotation angle of the display screen. When the rotation angle of the display screen reaches the maximum rotation angle, the encoder sends a signal to the drive mechanism 20, and the drive mechanism 20 stops working. Because the encoder is built into the motor of the drive mechanism 20, it occupies a small volume, which improves the integration of the posture adjustment component 100.

[0089] In another embodiment, the sensor 50 is installed in the motor of the driving mechanism 20. The sensor 50 may be a photosensitive sensor or a magnetic sensor. In this case, the sensor 50 may also detect the rotation angle or number of rotations of the motor, thereby detecting and limiting the rotation angle of the display screen.

[0090] Therefore, the posture adjustment component 100 of the present application uses a sensor 50 to detect the rotation angle of the display screen, and then limits the rotation range of the display screen relative to the bracket 10, which can limit the rotation range of the display screen and is beneficial to controlling the accuracy of the rotation angle of the display screen, so that the display screen can stop at the position required by the user in the current scene.

[0091] It is understandable that the drive mechanism 20 is provided with a motor controller, and the drive mechanism 20 is connected to the sensor 50 through the motor controller to receive the detection signal of the sensor 50. The motor controller can determine whether the mounting seat 90 is located at the preset position according to the received detection signal, and send a start-stop command to the motor in the drive mechanism 20.

[0092] In one embodiment, the transmission mechanism 30 includes a deceleration mechanism 80 and a housing, at least part of the sensor 50 is located in the housing, and the sensor 50 is used to sense the deceleration mechanism 80 to detect the rotation angle of the display screen relative to the bracket 10 .

[0094] In one embodiment, if Figure 7 As shown, the first sensor 51 is disposed on the first partition 12 . The first sensor 51 may be an angle sensor. The first sensor 51 detects the rotation angle of the transmission mechanism 30 , and limits the current position of the display screen by limiting the rotation angle of the transmission mechanism 30 .

[0095] In one embodiment, the transmission mechanism 30 includes a reduction mechanism 80, which has a shell, the inner cavity of the shell is connected to the accommodating cavity 11 of the bracket 10, and the first sensor 51 can also be arranged in the shell to determine the current position of the display screen by sensing the rotation angle of the internal components of the reduction mechanism 80.

[0096] The above-mentioned various embodiments can detect the current position of the display screen through the first sensor 51, thereby limiting the rotation angle of the display screen.

[0097] In one embodiment, the posture adjustment component 100 includes a circuit board 40 and a connector 41. The circuit board 40 is located in the second area 112. A connecting hole is provided on the first partition 12. The connecting hole connects the first area 111 and the second area 112. The connector 41 passes through the connecting hole. The connector 41 is used to conduct the sensor 50 and the circuit board 40.

[0098] In one embodiment, if Figure 8As shown, the second area 112 is provided with a circuit board 40, and the circuit board 40 is communicatively connected between the sensor 50 and the driving mechanism 20. The circuit board 40 can receive and analyze the detection results of one or more sensors 50, and integrate the detection results to determine the rotation angle of the display, so as to obtain the current position of the display more accurately, and then control the start and stop of the driving mechanism 20 according to the current position of the display to limit the rotation angle of the display screen.

[0099] In one embodiment, the circuit board 40 can also control the display screen to start and stop at any time. The circuit board 40 is communicated with the input device and receives the user's instructions through the input device. For example, a voice recognition device recognizes the user's instructions, the user operates the control panel or buttons, etc. After receiving the user's instructions, the circuit board 40 controls the drive mechanism 20 to realize the start and stop of the display screen at any time.

[0100] In one embodiment, the posture adjustment component 100 includes a flexible circuit board, the circuit board 40 is fixed to the second area 112, one end of the flexible circuit board is connected to the circuit board 40, and the other end extends into the first area 111 to connect with the sensor 50, so that the sensor 50 is connected to the circuit board 40 through the flexible circuit board. In this embodiment, the flexible circuit board can be bent and folded arbitrarily, and the flexible circuit board can extend into the first area, and the setting is more flexible.

[0101] In one embodiment, if Fig. 9 As shown, the circuit board 40 is disposed in the second area 112 and partially extends into the first area 111 . The sensor 50 is at least partially attached to the portion of the circuit board 40 extending into the first area 111 and is electrically connected to the circuit board 40 .

[0103] In one embodiment, the transmission mechanism 30 includes a transmission shaft 33, a worm wheel 32 and a worm 31. The transmission shaft 33 is connected to the mounting seat 90. The worm 31 is connected to the output end of the driving mechanism 20. The worm 31 is meshed with the worm wheel 32. The worm wheel 32 includes a mounting hole. The worm wheel 32 is mounted on the outer side of the transmission shaft 33 through the mounting hole, so that the power output by the driving mechanism 20 is transmitted to the transmission shaft 33 through the worm wheel 32 and the worm 31.

[0104] In some embodiments, Fig.10As shown, the motor shaft axis of the motor in the driving mechanism 20 intersects with the axis of the transmission shaft 33. During the operation of the posture adjustment component 100, the motor in the driving mechanism 20 transmits power to the transmission mechanism 30, and the rotation axis of the power is changed by the transmission mechanism 30, thereby transmitting the power to the mounting seat 90, and the mounting seat 90 drives the display screen to rotate synchronously. This arrangement can reduce the overlap of the axial length of the transmission shaft 33 of the posture adjustment component 100 and the length of the worm 31, and can avoid the posture adjustment component 100 from having an excessively large size along the axial direction of the transmission shaft 33.

[0105] In other embodiments, Figure 1 and Figure 2 As shown, the motor shaft axis of the motor in the drive mechanism 20 is perpendicular to the axis of the transmission shaft 33. This arrangement can also prevent the axial length of the transmission shaft 33 of the posture adjustment component 100 from overlapping with the length of the transmission mechanism 30, and can also prevent the axial size of the posture adjustment component 100 along the transmission shaft 33 from being too large.

[0106] Therefore, the motor and the transmission shaft 33 in the driving mechanism 20 are staggered so that the motor shaft axis of the motor in the driving mechanism 20 intersects with the axis of the transmission shaft 33, which is beneficial to the spatial arrangement of the driving mechanism 20, the transmission mechanism 30 and the transmission shaft 33, thereby reducing the space occupied by the posture adjustment component 100.

[0107] The power output by the driving mechanism 20 is transmitted to the worm 31, and the worm 31 transmits the power to the worm wheel 32 through meshing, and changes the rotation axis of the power. The worm wheel 32 is fixed to the transmission shaft 33, and the worm 31 drives the transmission shaft 33 to rotate, thereby driving the display screen to rotate synchronously. The transmission mechanism 30 of the present application changes the rotation axis of the motor and transmits the power to the transmission shaft 33 through the mutual cooperation of the worm 31 and the worm wheel 32.

[0108] In other embodiments, the worm 31 and the worm wheel 32 of the transmission mechanism 30 may be bevel gears respectively. The above embodiments can all realize the function of the transmission mechanism 30 to change the axial direction of the power rotation.

[0109] In one embodiment, if Figure 3 As shown, the bracket 10 includes a bearing seat 15, in which a bearing is disposed, and a worm 31 partially extends into the bearing seat 15 and is rotatably connected to the bracket 10 via the bearing.

[0110] In one embodiment, the transmission mechanism 30 includes a housing and a reduction mechanism 80, the reduction mechanism 80 is located in the inner cavity formed by the housing, the reduction mechanism 80 is transmission-connected between the output end of the drive mechanism 20 and the input end of the transmission mechanism 30, one end of the worm 31 extends into the housing and meshes with the reduction mechanism 80, and the housing is fixedly connected to the bracket 10. The reduction mechanism 80 is used to adjust the rotation speed and torque transmitted from the motor in the drive mechanism 20 to the transmission shaft 33.

[0111] In one embodiment, if Figure 1 and Figure 2 As shown, one end of the transmission shaft 33 is fixedly connected to the mounting seat 90, and the transmission shaft 33 is fixedly connected to the display screen through the mounting seat 90. Compared with the end surface of the transmission shaft 33, the mounting seat 90 has a larger area, so that the contact area between the display screen and the mounting seat 90 is larger, and the mounting seat 90 can form a more reliable fixed connection with the display screen. At the same time, the size of the display screen can be set according to needs, and the area of ​​the mounting seat 90 can be changed to achieve mutual adaptation between the display screen and the mounting seat 90. In one embodiment, as Figure 2 As shown, the posture adjustment assembly 100 includes a damping member 61 and a first friction member 62, and the damping member 61 and the first friction member 62 are used to provide damping force during the rotation of the display screen relative to the bracket 10, ensuring the smooth rotation of the display screen and reducing noise. Specifically, the damping member 61 can be fixed to the mounting seat 90, and the first friction member 62 can be fixed to the bracket 10. The rotation of the transmission shaft 33 drives the damping member 61 located on the mounting seat 90 to rotate synchronously. During the rotation of the display screen, the damping member 61 and the first friction member 62 contact each other to generate damping force, ensuring the smooth rotation of the display screen and reducing noise during the rotation process.

[0112] In other embodiments, the damping member 61 may also be fixed to the transmission shaft 33 or the worm gear 32, and the damping member 61 rotates synchronously with the transmission shaft 33 or the worm gear 32. During the rotation of the display screen, the damping member 61 and the first friction member 62 contact each other to generate a damping force, which can also ensure the smooth rotation of the display screen and reduce noise during the rotation process.

[0113] In the above embodiment, the damping member 61 is fixed to the mounting seat 90, the transmission shaft 33 or the worm gear 32, and the first friction member 62 is fixed to the bracket 10. The damping member 61 rotates synchronously with the display screen, and the damping member 61 moves relative to the bracket 10 and the first friction member 62.

[0115] In one embodiment, the posture adjustment assembly 100 also includes a damping member 61 and at least two friction members. The bracket 10 is provided with a receiving compartment 64. The damping member 61 and at least two friction members are placed in the receiving compartment 64. One end of the damping member 61 is clamped between the two friction members, and the other end of the damping member 61 is used to connect to any one of the transmission mechanism 30, the mounting seat 90 or the driving mechanism 20.

[0116] In one embodiment, if Figure 11-Figure 14 As shown, the damping member 61 is fixed to the mounting seat 90 , and the first friction member 62 and the second friction member 63 clamp the damping member 61 so that the mounting seat 90 can rotate smoothly.

[0117] In one embodiment, the posture adjustment assembly 100 further includes a spring 66, one end of the spring 66 abuts against the bottom wall of the accommodation chamber 64, and the other end of the spring 66 abuts against a friction member;

[0118] In one embodiment, if Fig.12 and Fig.14 As shown, the spring 66 is connected between the bottom wall of the accommodating chamber 64 and the first friction member 62 .

[0119] In one embodiment, if Fig.12 As shown, the bottom wall of the accommodating chamber 64 is provided with a spring groove 641, and the spring groove 641 is used to accommodate at least part of the spring 66, so that the connection between the spring 66 and the bottom wall of the accommodating chamber 64 is more reliable.

[0120] In one embodiment, the posture adjustment assembly 100 further includes a cover plate 65 , which closes the accommodating chamber 64 , and the cover plate 65 abuts against another friction member.

[0121] In one embodiment, if Fig.11 and Fig.13 As shown, the cover plate 65 shields the accommodating chamber 64 and abuts against the second friction member 63 .

[0122] In the above embodiment, the damping member 61 is clamped by the first friction member 62 and the second friction member 63 so that the mounting seat 90 can rotate smoothly.

[0123] In one embodiment, if Fig.11 As shown, a groove 651 is provided on the side of the cover plate 65 facing the second friction member 63 , and the groove 651 is used to accommodate at least a portion of the second friction member 63 and limit the displacement of the second friction member 63 along the cover plate surface direction.

[0124] In one embodiment, the posture adjustment assembly 100 also includes screws, a first connecting hole is provided at one end of the accommodating chamber 64 adjacent to the cover plate 65, and a second connecting hole is provided on the cover plate 65, which is configured as follows: when the cover plate 65 closes the accommodating chamber 64, the second connecting hole corresponds to the first connecting hole, and some screws pass through the second connecting hole and extend into the first connecting hole.

[0125] In one embodiment, the screw can rotate relative to the cover plate 65 and the receiving chamber 64, so as to adjust the interval between the cover plate 65 and the receiving chamber 64 or the interaction force between the cover plate 65 and the friction member.

[0126] In one embodiment, if Fig.11 As shown, the screw can adjust the interaction force between the cover plate 65 and the second friction member 63 .

[0127] See also Figure 15-17 ,in Fig.15 A schematic diagram of the exploded structure of a posture adjustment component 100 provided in another embodiment of the present application is illustrated; Fig.16 A cross-sectional schematic diagram of a posture adjustment component 100 provided in an embodiment of the present application is illustrated; Fig.17 A partial structural schematic diagram of a posture adjustment component 100 provided in an embodiment of the present application is illustrated.

[0128] In one embodiment, if Figure 15-17 As shown, the damping member 61 is fixed to the worm wheel 32 , and the first friction member 62 and the second friction member 63 clamp the damping member 61 so that the worm wheel 32 can rotate smoothly.

[0129] exist Figure 2 In the illustrated embodiment, the damping member 61 is arc-shaped and has a larger contact surface. The damping member 61 is fixed on the mounting base 90 so that during the rotation of the display screen, the damping member 61 can always be in contact with the first friction member 62, thereby providing a damping force to ensure smooth rotation of the display screen.

[0130] In other embodiments, the damping member 61 may also be configured to be rectangular or polygonal. The rectangular or polygonal damping member 61 needs to cover the rotation area of ​​the first friction member 62, thereby ensuring that during the rotation of the display screen, the damping member 61 can always be in contact with the first friction member 62, thereby providing a damping force to ensure smooth rotation of the display screen.

[0131] Understandably, for Figure 11-Figure 14 The embodiment in which the middle damping member 61 is arranged on the mounting seat 90 and Figure 15-17In the embodiment where the middle damping member 61 is disposed on the worm gear 32, the aforementioned arc-shaped, rectangular or multi-shaped damping members 61 are also applicable, thereby providing a damping force to ensure the smooth rotation of the display screen.

[0132] In one embodiment, the accommodating cavity 11 has an opening, and the posture adjustment assembly 100 includes a protective shell 17 , which covers the opening to seal the accommodating cavity 11 .

[0133] In one embodiment, if Figure 3 As shown, the accommodating cavity 11 has an opening, and the posture adjustment assembly 100 includes a protective shell 17, and the protective shell 17 includes a first part and a second part, and the first part and the second part are used to enclose the first area 111 and the second area 112 respectively.

[0134] In one embodiment, if Figure 3 As shown, the bracket 10 includes a shielding shell 16, which is located on the side of the bracket 10 facing the mounting seat 90. The shielding shell 16 can separate the accommodating cavity 11 from the display screen to prevent splashing lubricating oil from contaminating the display screen, while also improving the protection capability of the accommodating cavity 11.

[0135] In one embodiment, if Figure 2 As shown, the posture adjustment assembly 100 includes a limit block 70, which is fixed to the bracket 10. The limit block 70 is used to contact the display screen when the display screen is rotated to a preset position and limit the rotation angle of the display screen.

[0136] In other embodiments, the limit block 70 can be fixed to the bracket 10 and contact the mounting seat 90 or the transmission mechanism 30, so that the display screen stops at a preset position and cannot continue to rotate. It can be understood that in some embodiments, the limit block 70 can also be fixed to components such as the transmission mechanism 30 and the mounting seat 90. When the display screen rotates to the preset position, the limit block 70 contacts the bracket 10, which can also have the effect of limiting the rotation angle of the display screen.

[0137] The setting of the limit block 70 can form a supplementary mechanical limit for the sensor 50. In the posture adjustment component 100 of the present application, when the motor of the drive mechanism 20 slips, or the components of the transmission mechanism 30 are misaligned, and the communication connection between the sensor 50 and the motor controller is not smooth, the limit block 70 can limit the rotation angle of the display screen through mechanical limit to avoid interference that may occur when the display screen rotates further after rotating to the preset position. On the other hand, after the limit block 70 forms a limit on the display screen, the motor shaft of the motor in the drive mechanism 20 cannot rotate, the motor is blocked and the current surges. At this time, the motor controller in the drive mechanism 20 detects that the current passing through the motor exceeds the preset threshold, and the motor controller can disconnect the power supply of the motor to avoid the surge of current damaging the motor.

[0138] Because the mechanical limit provided by the limit block 70 in the posture adjustment assembly 100 of the present application serves as an auxiliary measure for limiting the position of the sensor 50, during the operation of the posture adjustment assembly 100, the probability of the limit block 70 contacting the bracket 10 or other components is low, thereby ensuring the service life of the posture adjustment assembly 100 of the present application. The mechanical limit of the limit block 70 can prevent the display screen from exceeding the rotation range when the sensor 50 fails, and avoid interference and collision between the display screen and other structures of the vehicle, so as to ensure the safety of the display screen.
