[0050] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0051] The drive mechanism 10 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0052] Reference Figures 1-6 , Figure 8 According to the first aspect of the present invention, the drive mechanism 10 can be used to drive the screen 20 to move. For example, the drive mechanism 10 can be used in a vehicle. When the drive mechanism 10 is used in a vehicle, the screen 20 can be an in-vehicle display screen, and the drive mechanism 10 can drive the in-vehicle display screen of the vehicle to move.

[0053] The drive mechanism 10 includes a base 1, a swing seat 2, and a first drive assembly 5. The swing seat 2 is rotatably mounted on the base 1. The screen 20 is adapted to be connected to the swing seat 2 and is adapted to rotate relative to the base 1 following the swing seat 2. The trajectory of the screen 20 is approximately arc-shaped. For example, the base 1 can be fixed to the instrument panel 200 of a vehicle. The rotation axis of the swing seat 2 is parallel to the left-right direction, and the swing seat 2 can swing in the up-down direction.

[0054] When the user's position relative to the base 1 remains unchanged, as the screen 20 rotates relative to the base 1 along with the swing seat 2, the orientation of the screen 20 relative to the base 1 changes, the angle between the plane where the screen 20 is located and the plane where the base 1 is located changes, and the distance between the screen 20 and the user's face, as well as the angle between the user's line of sight and the screen 20 in the vertical direction, will change to some extent.

[0055] When a user needs to use screen 20, the user can rotate the swing base 2 to change the distance between screen 20 and the user's face, as well as the angle between the user's line of sight and screen 20 in the vertical direction, and adjust screen 20 to the desired position. This allows the user to see the content on screen 20 more clearly, makes it easier for the user to operate screen 20, and makes it more convenient and comfortable for the user to use screen 20, thus meeting the usage needs of different users.

[0056] The first drive assembly 5 is adapted to drive the swing seat 2 to rotate relative to the base 1. The first drive assembly 5 includes a first motor 51, a first transmission belt 52, a first pulley 53, and a second pulley 54. The first motor 51 is disposed on the base 1, the first pulley 53 is connected to the output shaft of the first motor 51, and the second pulley 54 is connected to the swing seat 2. The first transmission belt 52 is sleeved on the first pulley 53 and the second pulley 54. For example, the swing seat 2 has a swing shaft, the base 1 has a first shaft hole, the swing shaft is adapted to pass through the first shaft hole, and the swing shaft is adapted to rotate in the first shaft hole.

[0057] When the first drive assembly 5 is working, the first motor 51 can drive the swing seat 2 to rotate relative to the base 1 through the first pulley 53, the first transmission belt 52 and the second pulley 54. This can realize the electric adjustment of the swing seat 2 and the electric adjustment of the position of the screen 20. It is simple and convenient, and makes it easy for users to adjust the screen 20.

[0058] The first pulley 53 and the second pulley 54 are connected by the first transmission belt 52 to realize the transmission between the first pulley 53 and the second pulley 54. This transmission method is called belt drive. The belt drive transmission method has a simple structure, low production cost, and is convenient to use and maintain. It can reduce the production cost of the drive mechanism 10 and facilitate maintenance personnel to inspect the drive mechanism 10. The belt drive transmission method has fewer restrictions on the relative position relationship between the first pulley 53 and the second pulley 54, which makes it easier to place the first pulley 53 and the second pulley 54, and also makes it easier to place the first motor 51 and the swing seat 2, allowing the drive mechanism 10 to be set up more compactly.

[0059] Moreover, the belt drive has a certain buffering and vibration absorption effect, which makes the first drive component 5 run more smoothly and the noise generated by the first drive component 5 during operation is small, thereby reducing the noise generated by the drive mechanism 10 during operation and improving the overall performance of the drive mechanism 10.

[0060] According to the driving mechanism 10 of the present invention, by setting the first driving component 5 to drive the swing seat 2 to move relative to the base 1, the position and angle of the screen 20 can be electrically adjusted, changing the distance between the screen 20 and the user's face and the angle between the user's line of sight and the screen 20 in the vertical direction, adjusting the screen 20 to the position and angle desired by the user, so that the user can see the content on the screen 20 more clearly, so that the user can operate the screen 20 more conveniently, so that the user can use the screen 20 more conveniently and comfortably, and meet the usage needs of different users.

[0061] Reference Figures 7-9 , Figure 12 According to some embodiments of the present invention, the drive mechanism 10 further includes a movable member 3, which is disposed on the swing base 2. The movable member 3 is movable along a first direction, which is perpendicular to the rotation axis of the swing base 2. The screen 20 is adapted to be connected to the movable member 3 and is adapted to move with the movable member 3 in the first direction. When the screen 20 moves in the first direction, the distance between the screen 20 and the base 1 changes, the angle between the screen 20 and the base 1 remains unchanged, and the distance between the screen 20 and the user's face changes.

[0062] When a user needs to use the screen 20, the user can move the movable part 3 along the first direction to change the distance between the screen 20 and the user's face, and adjust the screen 20 to the position the user wants, so that the user can see the content on the screen 20 more clearly, and the user can operate the screen 20 more conveniently, meeting the usage needs of different users.

[0063] The swing base 2 swings along the rotation axis and moves in conjunction with the moving part 3 in the first direction, so that the adjustable range of the screen 20 can be formed into a fan-shaped area. When the angle between the screen 20 and the user's line of sight in the vertical direction is fixed, there can be multiple positions where the screen 20 is at the same distance from the user. When the distance between the screen 20 and the user is fixed, there can be multiple angles between the screen 20 and the user's line of sight in the vertical direction.

[0064] This allows for a wider range of adjustment for the screen 20, resulting in more combinations of distances between the screen 20 and the user's face, as well as vertical angles between the screen 20 and the user's line of sight. This allows users to select more suitable distances and vertical angles, enabling them to see the content on the screen 20 more clearly and operate it more conveniently. Ultimately, this makes using the screen 20 more convenient and comfortable, meeting the needs of different users.

[0065] Reference Figures 7-10 , Figure 12According to some embodiments of the present invention, the movable member 3 passes through the swing seat 2, and the outer peripheral wall of the movable member 3 is provided with external threads. The drive mechanism 10 also includes a second drive assembly 6, which includes a second motor 61, a second transmission belt 62, a third pulley 63 and a fourth pulley 64. The second motor 61 is disposed on the swing seat 2, for example, the second motor 61 can be disposed on the side of the swing seat 2 away from the base 1.

[0066] The third pulley 63 is connected to the output shaft of the second motor 61. The fourth pulley 64 is sleeved on the outside of the moving part 3. The fourth pulley 64 is fixed in position relative to the swing seat 2. The inner circumferential wall of the fourth pulley 64 has an internal thread. The internal thread of the fourth pulley 64 is adapted to the external thread of the moving part 3. The second transmission belt 62 is sleeved on the third pulley 63 and the fourth pulley 64.

[0067] The internal thread of the fourth pulley 64 is adapted to the external thread of the moving part 3, which can convert the rotational motion of the fourth pulley 64 into the linear motion of the moving part 3 along the first direction. When the second drive unit is working, the second motor 61 can drive the fourth pulley 64 to rotate through the third pulley 63 and the second transmission belt 62. When the fourth pulley 64 rotates, it can drive the moving part 3 to move along the first direction, realizing the electric adjustment of the moving part 3 along the first direction. This is simple and convenient, and makes it easy for users to adjust the screen 20.

[0068] By connecting the third pulley 63 and the fourth pulley 64 with a second transmission belt 62, transmission between the third pulley 63 and the fourth pulley 64 is achieved. This transmission method is called belt drive. Belt drive has a simple structure, low production cost, and is convenient to use and maintain. It can reduce the production cost of the drive mechanism 10 and facilitate maintenance personnel to inspect the drive mechanism 10. Belt drive has fewer restrictions on the relative positional relationship between the third pulley 63 and the fourth pulley 64, which facilitates the placement of the third pulley 63 and the fourth pulley 64, as well as the placement of the second motor 61 and the swing seat 2, allowing the drive mechanism 10 to be set up more compactly.

[0069] The belt drive has a certain buffering and vibration absorption effect, which makes the second drive component 6 run more smoothly and the noise generated by the second drive component 6 during operation is small, thereby reducing the noise generated by the drive mechanism 10 during operation and improving the overall performance of the drive mechanism 10.

[0070] Reference Figures 7-10 , Figure 12 According to some embodiments of the present invention, the movable member 3 is rotatably disposed on the swing seat 2, the rotation axis of the movable member 3 extends along a first direction, and the screen 20 can rotate around the rotation axis of the movable member 3 following the movable member 3.

[0071] When adjusting the screen 20, the user can first adjust the angle between the plane where the screen 20 is located and the plane where the base 1 is located to the angle required by the user, adjust the distance between the screen 20 and the base 1 to the position required by the user, and then rotate the moving part 3 to rotate the screen 20 at a certain angle on the plane where the screen 20 is located (for example, switch the screen 20 from portrait to landscape or from landscape to portrait) to conform to the user's usage habits and meet the user's different needs.

[0072] When the drive mechanism 10 is used in a vehicle, the screen 20 is located to the side and in front of the user, and the screen 20 is lower than the user's face. The movable part 3 is rotatably mounted on the swing seat 2. The user can rotate the movable part 3 to rotate the screen 20 by a certain angle. When the user tilts their head to the side facing the screen 20 and looks down at the screen 20, the user's face can be directly facing the screen 20, so that the screen 20 is in the center of the user's field of vision. This allows the user to view the screen 20 more conveniently and comfortably without having to turn or tilt their head significantly.

[0073] Reference Figures 7-10 , Figure 12 According to some embodiments of the present invention, the drive mechanism 10 further includes a third drive assembly 7, which includes a third motor 71, a third transmission belt 72, a fifth pulley 73, and a sixth pulley 74. The third motor 71 is disposed on the swing seat 2, for example, the third motor 71 may be disposed on the side of the swing seat 2 away from the base 1. The fifth pulley 73 is connected to the output shaft of the third motor 71, the sixth pulley 74 is sleeved on the moving member 3, and the sixth pulley 74 is fixedly connected to the moving member 3. The third transmission belt 72 is sleeved on the fifth pulley 73 and the sixth pulley 74.

[0074] When the third drive component 7 is working, the third motor 71 can drive the sixth pulley 74 to rotate through the fifth pulley 73 and the third transmission belt 72. Since the sixth pulley 74 is fixedly connected to the moving part 3, the rotation of the sixth pulley 74 can drive the moving part 3 to rotate, thereby driving the screen 20 to rotate and realizing the electric adjustment of the screen 20 rotation. This is simple, convenient, and easy for users to adjust the screen 20.

[0075] By connecting the fifth pulley 73 and the sixth pulley 74 with a third transmission belt 72, transmission between the fifth pulley 73 and the sixth pulley 74 is achieved. This transmission method is called belt drive. Belt drive has a simple structure, low production cost, and is convenient to use and maintain. It can reduce the production cost of the drive mechanism 10 and facilitate maintenance personnel to inspect the drive mechanism 10. Belt drive has fewer restrictions on the relative positional relationship between the fifth pulley 73 and the sixth pulley 74, which facilitates the placement of the fifth pulley 73 and the sixth pulley 74, as well as the placement of the third motor 71 and the swing seat 2, allowing the drive mechanism 10 to be set up more compactly.

[0076] The belt drive has a certain buffering and vibration absorption effect, which makes the third drive component 7 run more smoothly, reduces the noise generated when the third drive component 7 is running, reduces the noise generated when the drive mechanism 10 is working, and improves the overall performance of the drive mechanism 10.

[0077] According to some embodiments of the present invention, a protrusion is provided on one of the outer peripheral wall of the movable member 3 and the inner peripheral wall of the sixth pulley 74, and a groove that mates with the protrusion is provided on the other of the outer peripheral wall of the movable member 3 and the inner peripheral wall of the sixth pulley 74. The groove extends along a first direction, and the protrusion is adapted to slide within the groove along the first direction. This allows the movable member 3 to be movable along the first direction while enabling the sixth pulley 74 to drive the movable member 3 to rotate. For example, the movable member can be a lead screw spline shaft.

[0078] By using the engagement of protrusions and grooves, the sixth pulley 74 can limit the movement of the moving part 3 in the circumferential direction, preventing the moving part 3 from rotating relative to the sixth pulley 74 in the first direction. This allows the sixth pulley 74 to reliably drive the moving part 3 to rotate, ensuring the structural reliability of the third drive assembly 7, ensuring the structural reliability of the drive mechanism 10, and improving the overall performance of the drive mechanism 10.

[0079] Optionally, on the first reference plane, the outer peripheral wall of the movable member 3 has a non-circular profile (e.g., a regular hexagon), and the inner peripheral wall of the sixth pulley 74 is formed to match the profile of the outer peripheral wall of the movable member 3. The first reference plane is perpendicular to the first direction. This ensures that the movable member 3 is movable along the first direction while allowing the sixth pulley 74 to drive the movable member 3 to rotate, preventing the movable member 3 from rotating relative to the sixth pulley 74 along the first direction. This ensures that the sixth pulley 74 can reliably drive the movable member 3 to rotate, guaranteeing the structural reliability of the third drive assembly 7 and the drive mechanism 10, and improving the overall performance of the drive mechanism 10.

[0080] Reference Figures 7-12 In some embodiments of the present invention, the drive mechanism 10 further includes a connecting plate 41 and a rotating member 42. The connecting plate 41 is connected to the moving member 3, and the rotating member 42 is rotatably connected to the connecting plate 41. The screen 20 is adapted to be connected to the rotating member 42. The rotation axis of the rotating member 42 and the connecting plate 41 is perpendicular to the first direction, and the rotation axis of the rotating member 42 and the connecting plate 41 is perpendicular to the rotation axis of the swing seat 2.

[0081] This allows the screen 20 to rotate around the axis of rotation between the rotating component 42 and the connecting plate 41, enabling the screen 20 to tilt towards the left or right side of the base 1. This changes the angle between the user's line of sight and the screen 20 in the left-right direction, thereby increasing the adjustable range of the screen 20's angle relative to the user. This allows the user to select a more suitable angle between the screen 20 and their line of sight in the left-right direction, making it easier for the user to see the content on the screen 20 and use the screen 20 more conveniently and comfortably, thus meeting the usage needs of different users.

[0082] Reference Figures 7-12 In some embodiments of the present invention, the drive mechanism 10 further includes a first pull wire structure 8, which includes a first spring 82, a first pull wire 83, and a first electric push rod 81. The first spring 82 is disposed between the connecting plate 41 and the screen 20 or the rotating member 42. The first pull wire 83 passes through the first spring 82, and one end of the first pull wire 83 is connected to the screen 20 or the rotating member 42, while the other end of the first pull wire 83 is connected to the first electric push rod 81. The first electric push rod 81 can drive the rotating member 42 to rotate relative to the connecting plate 41.

[0083] The following description uses an example where the first spring 82 is located between the connecting plate 41 and the screen 20, and one end of the first pull wire 83 is connected to the screen 20:

[0084] When the drive mechanism 10 is working, the first electric push rod 81 can pull the screen 20 by tightening the first pull cable 83, causing the screen 20 to rotate around the rotation axis of the rotating member 42 and the connecting plate 41, tilting the screen 20 towards the left (or right) side of the base 1, and the first spring 82 is compressed. When the first electric push rod 81 moves in the opposite direction to tightening the first pull cable 83, the first pull cable 83 is released, and the first spring 82 can drive the screen 20 to rotate around the rotation axis of the rotating member 42 and the connecting plate 41 under the action of elastic force, tilting the screen 20 towards the right (or left) side of the base 1. This allows for electric adjustment of the angle between the screen 20 and the user's line of sight in the left-right direction, which is simple, convenient, and easy for the user to adjust the screen 20.

[0085] By setting the first pull wire structure 8, the screen 20 can be tilted to the left and right sides of the base 1, which facilitates tilting and resetting the screen 20 in the left and right directions. This allows for adjustment of the angle between the screen 20 and the user's line of sight in the left and right directions. The structure is simple, easy to use, and easy to manufacture, which can reduce production costs. Moreover, the first pull wire structure 8 is a flexible component that is easy to bend, which facilitates the wiring layout. The first pull wire structure 8 can make the structure of the drive mechanism 10 more compact.

[0086] Reference Figures 7-12In some embodiments of the present invention, the drive mechanism 10 further includes an output plate 43, the screen 20 is adapted to be connected to the output plate 43, the output plate 43 is rotatably connected to the rotating member 42, and the rotation axis between the output plate 43 and the rotating member 42 is perpendicular to the rotation axis between the connecting plate 41 and the rotating member 42.

[0087] With this configuration, when the output board 43 rotates, the screen 20 can rotate around the rotation axis between the output board 43 and the rotating component 42, tilting towards the upper or lower side of the base 1, changing the angle between the user's line of sight and the screen 20 in the vertical direction, thereby increasing the adjustable range of the screen 20 relative to the user, meeting the usage needs of different users, and making it more convenient and comfortable for users to use the screen 20.

[0088] When the output plate 43 rotates around the rotation axis between the output plate 43 and the rotating member 42, the rotating member 42 can rotate around the rotation axis between the rotating member 42 and the connecting plate 41, thereby realizing the angle adjustment of the screen 20 in the vertical direction and the angle adjustment of the screen 20 in the horizontal direction, so that the user can adjust the angle of the screen 20 more conveniently and effectively.

[0089] The rotation of the output plate 43 and the rotation of the rotating component 42 work together to form a universal joint structure, which makes the adjustable trajectory of the screen 20 relative to the connecting plate 41 roughly form an umbrella surface.
