For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0066] Next, reference is made to Figures 1-18 Describe the actuator 100 of the display terminal 200 according to an embodiment of the present invention, where the display terminal 200 may be a touch screen, etc., and the actuator 100 may be mounted on a fixed object such as a vehicle or a wall. In a specific example of the present invention, the actuator 100 is mounted on the vehicle body.

[0067] As Figures 1-12 shown, the actuator 100 of the display terminal 200 according to an embodiment of the present invention includes: a mounting bracket 1, a rotating disk 2 and an outer sleeve 5, where the mounting bracket 1 is used to mount the display terminal 200. Specifically, the mounting bracket 1 and the display terminal 200 (provided with corresponding interface structures) may be connected by bolts, or the mounting bracket 1 may be integrated on the back of the display terminal 200.

[0068] One of the rotating disk 2 and the mounting bracket 1 is provided with a mating groove 3, and the other of the rotating disk 2 and the mounting bracket 1 is provided with a mating projection 4, and the mating projection 4 extends into the mating groove 3. An outer member 5 is sleeved outside the mating groove 3, and the outer member 5 is configured such that the mating projection 4 contacts the mating groove 3 so that the rotating disk 2 can drive the mounting bracket 1 to rotate synchronously. Optionally, the mating projection 4 is formed as a sphere, which can facilitate the assembly of the mating projection 4. Of course, it can be understood that the mating projection 4 can also be formed into other shapes, such as a cylindrical shape. Preferably, at least a part of the peripheral wall of the mating groove 3 is an elastic peripheral wall, and the outer member 5 presses the elastic peripheral wall to deform and contact the mating projection 4 so that the rotating disk 2 can drive the mounting bracket 1 to rotate synchronously. Thereby, it is convenient for the assembly of the outer member 5 and improves the reliability when the rotating disk 2 and the mounting bracket 1 rotate synchronously.

[0069] Specifically, it can be that the rotating disk 2 is provided with a mating groove 3, and the mounting bracket 1 is provided with a mating projection 4 extending into the mating groove 3. It can also be that the rotating disk 2 is provided with a mating projection 4, and the mounting bracket 1 is provided with a mating groove 3 for accommodating the mating projection 4. It can be understood that the rotating disk 2 can cooperate with the driving unit 7, and the driving unit 7 drives the rotating disk 2 to rotate.

[0070] When assembling the rotating disk 2 and the mounting bracket 1, first insert the mating projection 4 into the mating groove 3, and then fix the outer member 5 sleeved outside the mating groove 3. During the process of fixing the outer member 5, the outer member 5 makes the inner peripheral wall of the mating groove 3 contact the mating projection 4 so that the rotating disk 2 and the mounting bracket 1 are relatively fixed. During the rotation of the rotating disk 2, it can drive the mounting bracket 1 to rotate synchronously, thereby driving the display terminal 200 to rotate to change the display angle of the display terminal 200.

[0071] According to the actuator 100 of the embodiment of the present invention, the pre-positioning installation between the mounting bracket 1 and the rotating disk 2 is realized by the cooperation of the mating projection 4 and the mating groove 3, and then the fixed installation between the mounting bracket 1 and the rotating disk 2 is realized by the way that the outer member 5 makes the inner peripheral wall of the mating groove 3 contact the mating projection 4, so that the assembly method between the rotating disk 2 and the mounting bracket 1 is simple, which can meet the installation requirements in a small space and is time-saving and labor-saving during the installation process.

[0072] Such as Figure 1 、 Figure 2 、 Figure 4 and Figure 12As shown, in some specific embodiments of the present invention, one of the rotating disk 2 and the mounting bracket 1 is provided with an annular fixing protrusion 6, the fixing protrusion 6 is sleeved outside the mating groove 3, and the outer sleeve member 5 cooperates with the fixing protrusion 6. That is to say, a part of the outer sleeve member 5 is fixed on the fixing protrusion 6, and the other end of the outer sleeve member 5 extends into the fixing protrusion 6 and contacts the peripheral wall of the mating groove 3 to squeeze the peripheral wall of the mating groove 3. Thereby, the fixing method of the outer sleeve member 5 is simple. Of course, it can be understood that the fixing method of the outer sleeve member 5 is not limited thereto. For example, the outer sleeve member 5 can be directly fixed on a part of the peripheral wall of the mating groove 3, or the outer sleeve member 5 can be directly fixed on the rotating disk 2 or the mounting bracket 1. Preferably, as Figure 8 and Figure 9 shown, the outer sleeve member 5 is a nut, so as to fix the outer sleeve member 5 outside the mating groove 3 by means of thread fit, making the fixing method of the outer sleeve member 5 simple, and making the extrusion of the outer sleeve member 5 on the peripheral wall of the mating groove 3 reliable, ensuring the fixing reliability between the mounting bracket 1 and the rotating disk 2. In a specific example of the present invention, the outer sleeve member 5 is threadedly engaged with the outer peripheral wall of the fixing protrusion 6.

[0073] As Figures 2-4 shown, according to some embodiments of the present invention, the mating groove 3 is defined by a plurality of convex blocks 30 arranged at intervals and arranged in a ring. That is to say, one of the mounting bracket 1 and the rotating disk 2 is provided with a plurality of convex blocks 30 arranged at intervals, and the plurality of convex blocks 30 are arranged in a ring to define the mating groove 3. A part of the plurality of convex blocks 30 extends out of the fixing protrusion 6, and the outer sleeve member 5 contacts at least the part of the plurality of convex blocks 30 that extends out of the fixing protrusion 6 to squeeze each convex block 30 to deform and contact the mating protrusion 4. Thereby, by using a plurality of convex blocks 30 arranged at intervals to define the mating groove 3, the structure of the mating groove 3 is simple and reliable.

[0074] In some embodiments of the present invention, as Figure 4 shown, the inner peripheral wall of the mating groove 3 is provided with a plurality of contact protrusions 31 arranged at intervals, and the plurality of contact protrusions 31 contact the mating protrusion 4. Thereby, by providing a plurality of contact protrusions 31, the friction force in contact with the mating protrusion 4 can be increased, further ensuring that the mounting bracket 1 and the rotating disk 2 can rotate synchronously. Optionally, each contact protrusion 31 is formed as a hemispherical shape. In a specific example of the present invention, as Figure 4 shown, the inner peripheral wall of each convex block 30 is provided with a plurality of contact protrusions 31, and in the axial direction, the contact protrusions 31 on each convex block 30 are distributed in two rows, so as to increase the friction force between the mating groove 3 and the mating protrusion 4.

[0075] As Figure 1 、 Figure 4 and Figure 6As shown, according to some embodiments of the present invention, a first protrusion 32 is provided in the fitting groove 3, and a first groove 40 is provided on the fitting protrusion 4. The first protrusion 32 extends into the first groove 40, thereby improving the assembly firmness between the mounting bracket 1 and the rotating disk 2. Optionally, the first protrusion 32 may be formed as a cylinder, and the cross-section of the inner peripheral wall of the first groove 40 may be formed as an annular shape.

[0076] In some specific embodiments of the present invention, such as Figure 2 、 Figure 3 、 Figures 10-12 As shown, a plurality of fitting protrusions 4 are provided on the rotating disk 2, and the fitting grooves 3 are provided on the mounting bracket 1. It can be understood that each fitting protrusion 4 correspondingly extends into one of the fitting grooves 3. Thus, by the cooperation of the plurality of fitting protrusions 4 and the plurality of fitting grooves 3, the supporting force of the rotating disk 2 on the display terminal 200 can be increased, ensuring reliable and stable rotation of the rotating disk 2 driving the display terminal 200. Specifically, the plurality of fitting protrusions 4 are spaced apart in the length direction of the display terminal 200. In a specific example of the present invention, two fitting protrusions 4 are provided on the rotating disk 2. Specifically, when the display terminal 200 is in the vertical screen form as shown in Figure 2 and Figure 3 , the two fitting protrusions 4 can be vertically spaced apart. When the display terminal 200 is in the horizontal screen form as shown in Figures 10-12 , the two fitting protrusions 4 can be horizontally spaced apart.

[0077] Such as Figure 2 、 Figure 3 and Figure 10 As shown, in some embodiments of the present invention, the mounting bracket 1 includes a plurality of fixing sub-parts 10, and each fixing sub-part 10 is provided with a fitting groove 3. The plurality of fixing sub-parts 10 are in one-to-one correspondence with the plurality of fitting protrusions 4. Specifically, each fixing sub-part 10 is mounted to the display terminal 200. Thus, by providing a plurality of fixing sub-parts 10, the installation of the mounting bracket 1 can be facilitated, and at the same time, the cost can be reduced.

[0078] Of course, it can be understood that it can also be that a plurality of fitting grooves 3 are provided on the rotating disk 2, a plurality of fitting protrusions 4 are provided on the mounting bracket 1, and the plurality of fitting grooves 3 and the plurality of fitting protrusions 4 are in one-to-one correspondence.

[0079] Such as Figure 2 、 Figure 3 、 Figures 10-12As shown, in some embodiments of the present invention, the actuator 100 further includes a driving unit 7, and the driving unit 7 cooperates with the rotating disk 2 to drive the rotating disk 2 to rotate. Thus, by providing the driving unit 7, the display terminal 200 can be driven to rotate by the driving unit 7, achieving automatic angle adjustment. Specifically, the display terminal 200 can be rotated clockwise by the driving unit 7, and the display terminal 200 can also be rotated counterclockwise by the driving unit 7.

[0080] Further, as Figure 2 , Figure 3 , Figures 10-12 shown, the actuator 100 further includes a clutch unit 8. The clutch unit 8 includes a first engaging portion 80 and a second engaging portion 81. The first engaging portion 80 is provided on the rotating disk 2 to rotate synchronously with the rotating disk 2, and the second engaging portion 81 is connected to the output end of the driving unit 7. The first engaging portion 80 and the second engaging portion 81 are normally locked to each other. When a rotational force is manually applied to the mounting bracket 1, the first engaging portion 80 can rotate relative to the second engaging portion 81. Specifically, in the normal state, the first engaging portion 80 and the second engaging portion 81 are engaged with each other under the action of an axial preloading force and can transmit torque. The first engaging portion 80 and the second engaging portion 81 form a circumferential static friction force under the action of the axial preloading force, and this circumferential static friction force forms an opening force for the first engaging portion 80 and the second engaging portion 81 to rotate relative to each other. When the torque received by the first engaging portion 80 is greater than this opening force, the first engaging portion 80 and the second engaging portion 81 rotate relative to each other to change the engaging position. When the torque received by the first engaging portion 80 is less than this opening force, the first engaging portion 80 and the second engaging portion 81 are engaged with each other to transmit torque.

[0081] When the driving unit 7 is used to drive the rotating disk 2 to rotate, the first engaging portion 80 and the second engaging portion 81 are in a locked state. The driving unit 7 drives the second engaging portion 81 to rotate, the second engaging portion 81 drives the first engaging portion 80 to rotate synchronously, and when the first engaging portion 80 rotates, it drives the rotating disk 2 to rotate, thus achieving the purpose of controlling the rotation of the rotating disk 2 in the automatic mode. When a rotational force is manually applied to the mounting bracket 1, the torque applied to the mounting bracket 1 can be transmitted to the first engaging portion 80. When the torque is not greater than the above-mentioned opening force, the first engaging portion 80 and the second engaging portion 81 remain engaged and the display terminal 200 does not rotate. When the above-mentioned torque is greater than the above-mentioned opening force, the first engaging portion 80 can rotate relative to the second engaging portion 81, so the rotating disk 2 can be manually driven to rotate, thus achieving the purpose of controlling the rotation of the rotating disk 2 in the manual mode.

[0082] It can be understood that when a rotational force is applied to the mounting bracket 1, the display terminal 200 can be directly rotated to transmit the rotational force to the mounting bracket 1.

[0083] According to the actuator 100 of the display terminal 200 according to an embodiment of the present invention, by providing a clutch unit 8, the actuator 100 has an automatic mode and a manual mode, and the manual rotation of the display terminal 200 and the automatic rotation of the display terminal 200 can be coupled into a whole, and the two screen switching methods do not interfere with each other, meeting the needs of users.

[0084] In some specific embodiments of the present invention, the clutch unit 8 has a plurality of engagement positions. At the engagement positions, the first engagement portion 80 and the second engagement portion 81 rotate synchronously. When a rotational force is manually applied to the mounting bracket 1, the first engagement portion 80 is rotatable relative to the second engagement portion 81 to switch between a plurality of engagement positions. Thus, by providing a plurality of engagement positions, the requirement of the rotation angle can be met. Specifically, the clutch unit 8 may have four engagement positions, and the rotation angle between adjacent engagement positions may be 90°. That is to say, when the first engagement portion 80 is manually rotated by 90°, the first engagement portion 80 can be rotated from the previous engagement position to the next engagement position. Of course, it can be understood that the number of engagement positions and the rotation angle between adjacent engagement positions can be set according to actual situations.

[0085] In some embodiments of the present invention, as Figures 15-18 shown, one of the first engagement portion 80 and the second engagement portion 81 is provided with an engagement protrusion 82, and the other of the first engagement portion 80 and the second engagement portion 81 is provided with a plurality of engagement grooves 83. At the engagement position, the engagement protrusion 82 extends into the engagement groove 83. Specifically, in the automatic mode, the engagement protrusion 82 extends into the corresponding engagement groove 83, the first engagement portion 80 and the second engagement portion 81 are in the engagement position, and the driving unit 7 can drive the rotating disk 2 to rotate through the clutch unit 8. When a rotational force is manually applied to the display terminal 200, the second engagement portion 81 and the driving unit 7 remain relatively stationary axially, the first engagement portion 80 axially displaces relative to the second engagement portion 81, the engagement protrusion 82 is disengaged from the engagement groove 83, and when manually rotated to the next engagement position, the engagement protrusion 82 extends into the corresponding engagement groove 83 to achieve positioning. Thus, the cooperation mode between the first engagement portion 80 and the second engagement portion 81 is simple and reliable. Thus, the purpose of engagement is achieved through the cooperation of the engagement protrusion 82 and the engagement groove 83. Not only can clear positioning be achieved, but also a good feel can be taken into account during rotation, and it can be determined whether the rotation is in place.

[0086] In a specific example of the present invention, the first engagement portion 80 is provided with a plurality of engagement protrusions 82, and the second engagement portion 81 is provided with a plurality of engagement grooves 83. At each engagement position, the plurality of engagement protrusions 82 and the plurality of engagement grooves 83 are in one-to-one correspondence. Specifically, as Figure 15 and Figure 16As shown, there are four engaging protrusions 82 and four corresponding engaging grooves 83.

[0087] In some embodiments of the present invention, the end face of the rotating disk 2 facing the second engaging portion 81 is configured as the first engaging portion 80, and the engaging protrusions 82 are provided on the rotating disk 2, thereby reducing the weight of the actuator 100. Specifically, the engaging protrusions 82 and the rotating disk 2 can be detachably connected, so that when the engaging protrusions 82 are affected in use due to wear or the like, the engaging protrusions 82 can be replaced, which is convenient for reducing the maintenance cost. Of course, it can be understood that the engaging protrusions 82 and the rotating disk 2 can also be an integral part.

[0088] In some other embodiments of the present invention, the rotating disk 2 and the first engaging portion 80 are independently processed and formed parts, and the first engaging portion 80 is fixed to the rotating disk 2. Specifically, the first engaging portion 80 can be fixed to the rotating disk 2 by means of spline connection, screw connection, snap connection, etc. As Figure 16 shown, in some specific examples of the present invention, a plurality of positioning grooves 801 are provided on the outer peripheral wall of the first engaging portion 80, and a plurality of positioning protrusions (not shown in the figure) are provided on the rotating disk 2. The plurality of positioning protrusions extend into the plurality of positioning grooves 801 one by one, thereby limiting the circumferential freedom degree of the first engaging portion 80 relative to the rotating disk 2, so that the first engaging portion 80 and the rotating disk 2 can rotate synchronously.

[0089] In some embodiments of the present invention, as Figures 15-17 shown, both the engaging groove 83 and the engaging protrusion 82 have an arc-shaped cross-section, and the root width of the engaging protrusion 82 is greater than the width of the top end of the engaging protrusion 82. The width of the open end of the engaging groove 83 is greater than the width of the bottom of the engaging groove 83, and the width of the engaging protrusion 82 gradually decreases from the root to the top end.

[0090] When the arc-shaped side surface of the engaging protrusion 82 abuts against the arc-shaped side wall of the engaging groove 83, torque can be transmitted between the first engaging portion 80 and the second engaging portion 81; when the torque between the first engaging portion 80 and the second engaging portion 81 is greater than the above-mentioned opening force, the arc-shaped side surface of the engaging protrusion 82 and the arc-shaped side wall of the engaging groove 83 slide relative to each other. When the engaging protrusion 82 abuts against the end face of the first engaging portion 80 or the second engaging portion 81, the first engaging portion 80 and the second engaging portion 81 are disengaged, and the engaging protrusion 82 slides along the end face of the first engaging portion 80 or the second engaging portion 81 to another engaging groove 83, that is, the rotation of the display terminal 200 is realized.

[0091] Due to the provision of the arc-shaped engagement groove 83 and the arc-shaped engagement projection 82, when a large torque is applied to the first engagement portion 80 and the second engagement portion 81, they can be disengaged by the relative sliding of the arc-shaped surfaces, and it is not easy to get stuck. After the engagement groove 83 and the engagement projection 82 are disengaged, the arc-shaped engagement projection 82 slides along the end face of the second engagement portion 81. The frictional force between the first engagement portion 80 and the second engagement portion 81 is small, which facilitates rapid sliding to the next engagement position and is not easy to get stuck.

[0092] As Figures 15-18 shown, when observing along the axial direction of the clutch unit 8, both the engagement groove 83 and the engagement projection 82 are fan-shaped rings concentric with the first engagement portion 80 or the second engagement portion 81, and both the engagement groove 83 and the engagement projection 82 have a fan-shaped ring cross-section concentric with the first engagement portion 80 or the second engagement portion 81. That is to say, the width of the engagement groove 83 gradually increases from the inside to the outside in the radial direction, and the width of the engagement projection 82 gradually increases from the inside to the outside in the radial direction. It can be understood that when the first engagement portion 80 and the second engagement portion 81 transmit torque, the moment received by the outer end is large. By setting the above structure, the force-receiving area of the outer end can be increased, the pressure received by the outer end can be reduced, the strength of the outer end can be enhanced, and fracture can be prevented.

[0093] As Figures 15-17 shown, the width of at least a part of the engagement projection 82 is greater than the width of the open end of the engagement groove 83, and at least one side of the engagement projection 82 abuts against the corresponding side of the engagement groove 83 so that the engagement projection 82 engages with the engagement groove 83. Thereby, it can be ensured that each engagement projection 82 engages with the corresponding engagement groove 83, and when there is a certain error between the actual rotation angle and the designed angle of the display terminal 200, each engagement projection 82 still engages with the corresponding engagement groove 83, preventing the situation where some engagement projections 82 are engaged with the corresponding engagement grooves 83 in a virtual manner. The situation of not being able to engage due to manufacturing tolerances can be avoided, the requirement for the position accuracy of the first engagement portion 80 and the second engagement portion 81 can be reduced, and the shaking and instability of the components caused by the gaps generated by production errors can be avoided.

[0094] As Figure 18 shown, both the engagement groove 83 and the engagement projection 82 have an arc-shaped cross-section, and the width of the root of the engagement projection 82 is greater than the width of the top of the engagement projection 82, the width of the open end of the engagement groove 83 is greater than the width of the bottom of the engagement groove 83, and the width of the engagement projection 82 gradually decreases from the root to the top.

[0095] The engaging groove 83 and the engaging protrusion 82 are in a circumferential clearance fit, that is, the width of the engaging groove 83 in the circumferential direction is greater than the width of the engaging protrusion 82 in the circumferential direction, the depth of the engaging groove 83 is greater than the height of the engaging protrusion 82, the width of the open end of the engaging groove 83 is greater than the width of the root of the engaging protrusion 82, and one side of the engaging protrusion 82 is pressed against one side of the engaging groove 83 so that the engaging protrusion 82 and the engaging groove 83 are engaged. In this way, the same side of the plurality of engaging protrusions 82 in the circumferential direction presses against one side wall of the corresponding engaging groove 83 to achieve the engagement of the first engaging portion 80 and the second engaging portion 81.

[0096] Preferably, as Figure 17 and Figure 18 shown, the width of the engaging groove 83 gradually decreases from the open end to the bottom, and the width of the engaging protrusion 82 gradually decreases from the root to the top. The width of the open end of the engaging groove 83 is smaller than the width of the root of the engaging protrusion 82. In other words, the central angle of the fan-shaped ring at the open end of the engaging groove 83 is smaller than the central angle of the fan-shaped ring at the root of the engaging protrusion 82. When the first engaging portion 80 and the second engaging portion 81 are engaged, the engagement position of the engaging protrusion 82 and the engaging groove 83 is related to the circumferential alignment position of the engaging protrusion 82 and the engaging groove 83.

[0097] It can be understood that, ideally (without considering the machining errors of the engaging protrusion 82 and the engaging groove 83), the two sides of each engaging protrusion 82 at the same height are respectively pressed against the two side edges of the open end of the engaging groove 83; due to machining errors, for example, the included angle between two adjacent engaging protrusions 82 is not equal to 90°, the widths of each engaging protrusion 82 are not equal, and some engaging protrusions 82 and the corresponding engaging grooves 83 may be pressed unilaterally. At least one side of the engaging protrusion 82 is pressed against the corresponding side of the engaging groove 83 so that the engaging protrusion 82 and the engaging groove 83 are engaged.

[0098] That is to say, by setting the engaging protrusion 82 and the engaging groove 83 in the above structural form, it can be ensured that each engaging protrusion 82 is engaged with the corresponding engaging groove 83, and when there is a certain error between the actual rotation angle and the designed angle of the display terminal 200, each engaging protrusion 82 remains engaged with the corresponding engaging groove 83, preventing the situation of virtual engagement between some engaging protrusions 82 and the corresponding engaging grooves 83. On the other hand, a part of the engaging protrusion 82 is engaged with the engaging groove 83, which is convenient for the engaging protrusion 82 to slide out of the engaging groove 83 during manual operation.

[0099] The depth of the engaging groove 83 is smaller than the height of the engaging protrusion 82, so that the strength of the second engaging portion 81 is high.

[0100] In some embodiments of the present invention, in order to reduce the friction between the first engaging portion 80 and the second engaging portion 81, improve the lifespan of the components, and to a certain extent improve the feel during manual rotation, an oil storage groove 84 is provided on the end surface of at least one of the first engaging portion 80 and the second engaging portion 81. In a specific example of the present invention, as Figure 15 shown, an oil storage groove 84 is provided on the end surface of the second engaging portion 81 facing the first engaging portion 80.

[0101] As Figure 11 and Figure 12 shown, in some embodiments of the present invention, the actuator 100 of the display terminal 200 further includes an elastic member 15 for applying a pressing force towards the first engaging portion 80 to the second engaging portion 81. The elastic member 15 is provided between the rotating disk 2 and the driving unit 7. Preferably, the elastic member 15 can be a spring.

[0102] In the manual mode, when a torque is applied to the first engaging portion 80, for example, when the display terminal 200 is manually rotated, a torque is generated between the first engaging portion 80 and the second engaging portion 81. When this torque is greater than the above-mentioned opening force, the engaging protrusion 82 gradually disengages from the engaging groove 83. After the engaging protrusion 82 disengages from the engaging groove 83, the second engaging portion 81 and the driving unit 7 are axially stationary relative to the vehicle body, the elastic member 15 is compressed, the first engaging portion 80 moves axially in a direction away from the second engaging portion 81, and the display terminal 200 also moves axially in a direction away from the second engaging portion 81, that is, the display terminal 200 moves backward (towards the rear of the vehicle body).

[0103] According to the actuator 100 of the embodiment of the present invention, by applying an axial pre-tightening force between the second engaging portion 81 and the first engaging portion 80 through the elastic member 15, a sufficient system positive pressure between the contact surfaces of each component is ensured, the friction force of the axial rotation of the first engaging portion 80 and the second engaging portion 81 is ensured. At the same time, it can effectively prevent the micro-vibration rotation of the display terminal 200 caused by the backlash in the driving unit 7, avoid the visual retention phenomenon caused by it, and can also prevent the risk of damage to the driving unit 7 and the clutch unit 8 caused by micro-vibration gear jamming during vibration shock. It can effectively isolate the influence of external shocks on the display terminal 200, can effectively protect the actuator 100, improve the reliability of the actuator 100, and ensure the anti-shake and anti-vibration performance of the actuator 100.

[0104] It should be noted that the system positive pressure can also be obtained in other ways, for example, by using a shoulder limit at one end and riveting, an axial retaining ring or nut tightening at the other end.

[0105] In a further embodiment of the present invention, as Figure 11As shown in the figure, the rotating disk 2 includes a mounting shaft 21 that sequentially passes through the clutch unit 8 and the drive unit 7. An elastic member 15 is sleeved on the mounting shaft 21. One end of the elastic member 15 abuts against and is fixed to the axial limiting member 9 of the mounting shaft 21, and the other end of the elastic member 15 abuts against the housing 72 of the drive unit 7. The axial fixed connection among the axial limiting member 9, the mounting shaft 21, and the rotating disk 2 limits the axial length of the system. In this way, a certain positive pressure can be maintained between the components connected in series (the pressure is provided by the compression deformation of the elastic member 15), realizing the locking function of the system, and at the same time realizing the axial limitation among the components. Optionally, the axial limiting member 9 can be a snap ring sleeved on the mounting shaft 21.

[0106] Preferably, as Figure 11 shown, the other end of the elastic member 15 abuts against the housing 72 of the drive unit 7 through a thrust bearing 16, and the thrust bearing 16 can be a thrust bearing. Thus, when the display terminal 200 rotates, the housing 72 of the drive unit 7 remains stationary, and the mounting shaft 21 rotates. By setting the thrust bearing 16, the friction between the elastic member 15 and the housing 72 of the drive unit 7 can be significantly reduced. The housing 72 of the drive unit 7 has an axial limiting portion 7212, and an annular mounting groove is formed at the axial limiting portion 7212. The thrust bearing 16 is installed in the mounting groove and abuts against one side (the bottom wall of the mounting groove) of the axial limiting portion 7212. A part of the elastic member 15 is also located in the mounting groove. In this way, the axial length of the entire actuator 100 is short.

[0107] In some embodiments of the present invention, the mounting shaft 21 is of a hollow structure, which is convenient for wire routing, making the wire routing of the harness behind the screen reasonable and beautiful. A rounded corner structure can be set at the wire outlet to prevent wire cutting.

[0108] As Figures 11-12 shown, in some embodiments of the present invention, the drive unit 7 includes: a power source 70 and a speed reduction unit 71. The output end of the power source 70 is connected to the input end of the speed reduction unit 71, and the output end of the speed reduction unit 71 is connected to the rotating disk 2. Thus, by setting the speed reduction unit 71, the rotation speed of the rotating disk 2 can be made slower to meet the viewing requirements. Specifically, the power source 70 can be a motor, an oil pump, an air pump, etc. The speed reducer can be a gear speed reducer, a belt drive reduction, and the speed reducer can also be a worm gear transmission mechanism, etc. The speed reducer can be a single-stage reduction mechanism or a multi-stage reduction mechanism.

[0109] In some embodiments of the present invention, in order to improve the driving experience of the customer and to ensure the smooth rotation of the display terminal 200, the rotation speed of the display terminal 200 can be controlled within 6 - 10 r / min. Therefore, the value range of the transmission ratio of the speed reduction unit 71 is approximately 1500 - 2000. A planetary gear train speed reducer or a double-worm reduction system with two-stage worm and helical gears can be selected according to the specific structural layout.

[0110] In some specific embodiments of the present invention, as Figure 12 shown, the reduction unit 71 is a worm gear reduction mechanism. The reduction unit 71 includes a first-stage worm 710, a first-stage gear 711, a second-stage worm 712, and a second-stage gear 713. The output end of the power source 70 is connected to the first-stage worm 710. The first-stage worm 710 meshes with the first-stage gear 711 to drive the first-stage gear 711 to rotate. The first-stage gear 711 cooperates with the second-stage worm 712 to drive the second-stage worm 712 to rotate. The second-stage worm 712 cooperates with the second-stage gear 713 to drive the second-stage gear 713 to rotate. The second-stage gear 713 is fixed on the second engagement portion 81 to drive the second engagement portion 81 to rotate. Thus, by adopting the worm gear reduction mechanism, the transmission ratio is large and the intersecting-axis arrangement can be realized. This mechanism is compact, small in volume, light in weight, and has smooth transmission and low noise. The overall layout of the reduction mechanism is flexible, facilitating wire routing, and is more suitable for the requirements of the compact space of the vehicle body and the vehicle weight limit. At the same time, it can also provide a better driving experience for users. Specifically, the first-stage gear 711 and the second-stage worm 712 can be coaxially arranged to achieve synchronous rotation. In some examples of the present invention, the power source 70 is a motor, and the first-stage worm 710 can be assembled on the motor shaft of the motor by an interference fit method.

[0111] Specifically, the second-stage gear 713 and the second engagement portion 81 can be integrally formed parts.

[0112] In some specific embodiments of the present invention, as Figures 11-14 shown, the housing 72 of the drive unit 7 includes a movement housing 720 and a sleeve 721. The power source 70 is arranged inside the movement housing 720. The sleeve 721 is fixed on the movement housing 720. The sleeve 721 is provided with a positioning hole 7210. The mounting shaft 21 of the rotating disk 2 passes through the positioning hole 7210. The sleeve 721 is provided with an axial limiting portion 7212. The second-stage gear 713 is rotatably supported on the sleeve 721. Thus, by providing the sleeve 721 and the movement housing 720, it is convenient for the assembly of the power source 70 and the reduction unit 71. Specifically, as Figure 13 and Figure 14 shown, the sleeve 721 is provided with a screw hole 7211. The sleeve 721 can be fixed on the movement housing 720 by screws.

[0113] When manually rotating the display terminal 200 to ensure that it can be rotated to a target angle, for example, the target angle can be 90°, in some embodiments of the present invention, a first positioning structure 20 is provided on the rotating disk 2, and a second positioning structure is provided on the housing 72 of the driving unit 7. The first positioning structure 20 and the second positioning structure cooperate to define the rotation angle of the rotating disk 2. Specifically, the first positioning structure 20 is a positioning pin, and the second positioning structure is an arc-shaped extending positioning groove. That is to say, the radian of the positioning groove is equal to the target rotation angle of the display terminal 200. When the rotating disk 2 rotates, the positioning pin slides in the positioning groove. When the positioning pin presses against one end of the positioning groove, it means that the display terminal 200 has rotated in place. Of course, it can be understood that the structures of the first positioning structure 20 and the second positioning structure are not limited to this. For example, the first positioning structure 20 can be a positioning pin, and the second positioning structure can be two spaced-apart limiting notches. When the positioning pin switches from pressing against one limiting notch to pressing against the other limiting notch, it means that the display terminal 200 has rotated in place.

[0114] In some embodiments of the present invention, such as Figure 2 and Figure 3 shown, the display terminal 200 is in a vertical screen form, and the driving unit 7 can drive the display terminal 200 to rotate left or right. In some other embodiments of the present invention, such as Figures 10-12 shown, the display terminal 200 is in a horizontal screen form, and the driving unit 7 can drive the display terminal 200 to rotate left or right. When the actuator 100 is applied to a vehicle, by driving the display terminal 200 to rotate left or right through the driving unit 7, the viewing needs of the driver and the co-driver can be met. It should be noted that in the description of the present invention, the display terminal 200 being in a vertical screen form means that the horizontal width of the display terminal 200 is less than the vertical length of the display terminal 200, and the display terminal 200 being in a horizontal screen form means that the horizontal length of the display terminal 200 is greater than the vertical width of the display terminal 200.

[0115] In some specific examples of the present invention, such as Figure 2 and Figure 3 shown, when the display terminal 200 is in a vertical screen form, in order to facilitate the fixing of the rotating disk 2 to the first engaging portion 80, the rotating disk 2 includes a first rotating bracket 22 and a second rotating bracket 23. A mating protrusion 4 is provided on the first rotating bracket 22, and an avoidance groove 220 is provided on the first rotating bracket 22. The second rotating bracket 23 is fixed to the first engaging portion 80. A part of the clutch unit 8 and the driving unit 7 extends into the avoidance groove 220. The first rotating bracket 22 and the second rotating bracket 23 are fixedly connected by a pin 24, and the first rotating bracket 22 and the second rotating bracket 23 can rotate synchronously.

[0116] In some embodiments of the present invention, such as Figure 12As shown, the actuator 100 further includes a safety device 17. The safety device 17 is connected to the drive unit 7. When the safety device 17 detects a shutdown condition, it controls the drive unit 7 to stop rotating. The shutdown conditions include detecting that the display terminal 200 rotates in place, the anti-pinch indication is activated due to an external obstacle encountered by the display terminal 200, etc. Thus, the safety of the actuator 100 can be improved. Specifically, the power source 70 is a motor, and the safety device 17 is a current-limiting circuit board. When it is detected that the current of the motor exceeds the set threshold current, the power supply of the motor is cut off, thereby realizing the anti-pinch and overload protection of the actuator 100. Specifically, the safety device 17 can be installed inside the housing 72 of the drive unit 7.

[0117] Specifically, after the power supply of the motor is cut off, the control system will judge whether the display terminal 200 is in an abnormal position according to the signal transmitted by the built-in gyroscope of the display terminal 200. If the signal transmitted by the gyroscope indicates that the display terminal 200 is in the landscape position or the portrait position, it means that the power supply of the motor is cut off due to reaching the position. Otherwise, it is determined that the display terminal 200 is in an abnormal position, and it is determined that the power supply of the motor is cut off abnormally due to encountering an obstruction, then a warning screen will appear to remind the customer to check for foreign objects. After the resistance disappears, it will be restarted and returned according to the customer's selection. The abnormal position determination includes manual operations in the automatic operation state. The actual abnormal position feedback processing can be designed according to the customer's requirements to define the software function. The limit locking structure of this solution can fully adapt to different software function definitions (regarding the control of abnormal positions) at the physical level.

[0118] As Figure 19 As shown, the vehicle 1000 according to an embodiment of the present invention includes: a display terminal 200 and an actuator 100. The actuator 100 is the actuator 100 of the display terminal 200 according to the above embodiment of the present invention. The actuator 100 is installed on the vehicle body of the vehicle 1000, and the display terminal 200 is installed on the actuator 100.

[0119] For the vehicle 1000 according to an embodiment of the present invention, by providing the actuator 100 according to the above embodiment of the present invention, the pre-positioning installation between the mounting bracket 1 and the rotating disk 2 is realized by the cooperation of the mating protrusion 4 and the mating groove 3, and then the fixed installation between the mounting bracket 1 and the rotating disk 2 is realized by making the inner peripheral wall of the mating groove 3 contact the mating protrusion 4 by means of the outer sleeve 5. Thus, the assembly method between the rotating disk 2 and the mounting bracket 1 is simple, which can meet the installation requirements in a small space and saves time and effort during the installation process.

[0120] Other components of the vehicle according to the embodiment of the present invention, such as the braking system and the driving control system, etc., and the operations are known to those of ordinary skill in the art and will not be described in detail here.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
