Description

Technical Field

[0001] The present invention relates to the technical field of display screen angle adjustment, and in particular to an actuator and a flip screen. Background Art

[0002] In the field of smart cockpits, when the vehicle-mounted display screen is folded, an actuator is generally used to drive the display screen to rotate. The output shaft set on the actuator is connected to the display screen, and then the display screen is driven to rotate horizontally or adjust the pitch forward and backward on the corresponding carrier, thereby achieving the angle adjustment of the display screen and the adjustment of unfolding and folding.

[0003] However, the current actuator functions are relatively simple. For horizontal angle adjustment or front and back folding, it is necessary to select an actuator with a specific angle output shaft. The functions are relatively simple and the adaptability is poor. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide an actuator and a flip screen, which solves the problem that the existing actuator has relatively single functions.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an actuator, including a housing and a first drive unit and a second drive unit arranged on the housing, the first drive unit including a first output shaft and a first drive part that drives the first output shaft to rotate, the second drive unit including a second output shaft and a second drive part that drives the second output shaft to rotate, wherein the first output shaft and the second output shaft are arranged non-parallel, and the two intersect or are in different planes.

[0006] Furthermore, the first output shaft is arranged vertically along the bottom surface of the housing, and the second output shaft is arranged horizontally along the bottom surface of the housing. The first output shaft and the second output shaft are in a non-planar vertical relationship within the housing.

[0007] By adopting the above technical solution, the space waste problem caused by the parallel arrangement of dual output shafts can be avoided by arranging them in different planes vertically or intersectingly. It not only maximizes the use of three-dimensional space, but also avoids the intersection of the motion trajectories of the two sets of drive units, reducing the risk of mechanical interference. At the same time, the two output shafts distributed vertically and horizontally also correspond to the horizontal angle adjustment and the front and rear pitch adjustment of the display screen.

[0008] Furthermore, the first driving part includes a first motor and a first gear set, the first gear set includes a first driving gear, a first duplex gear and a first driven gear, the first driving gear is connected to the output end of the first motor, the first driven gear is coaxially fixed to the outside of the first output shaft, and the first duplex gear is used to link the first driven gear and the first driving gear.

[0009] By adopting the above technical solution, the double gear set can optimize the transmission path, reduce energy loss, and ensure the stability of the output shaft rotation.

[0010] Furthermore, the second driving part includes a second motor and a second gear set, the second gear set includes a second driving gear, a second duplex gear and a second driven gear, the second driving gear is connected to the output end of the second motor, the second driven gear is coaxially fixed to the outside of the second output shaft, and the second duplex gear is used to link the second driven gear and the second driving gear.

[0011] By adopting the above technical solution, which is similar to the structure of the first drive part, it is easy to mass produce and reduce manufacturing costs. At the same time, the same gear set design ensures that the transmission characteristics of the two sets of drive units are consistent, thereby improving synchronization.

[0012] Furthermore, the axial direction of the second driving gear is parallel to the axial direction of the second duplex gear, and the axial direction of the first driving gear is perpendicular to the axial direction of the first duplex gear.

[0013] By adopting the above technical solution, the axial direction of the second drive gear is parallel to the axial direction of the second duplex gear, and the two can be linked by spur gears. The axial direction of the first drive gear is perpendicular to the axial direction of the first duplex gear, and the two use helical gears, so that the horizontally placed first motor can be linked to the vertically arranged first output shaft through the first duplex gear.

[0014] Furthermore, the shell includes a front shell and a bottom shell, which together form a cavity. The inner walls of the front shell and the bottom shell are provided with isolation ribs, which divide the cavity into multiple spaces to accommodate the first drive unit and the second drive unit through different spaces.

[0015] By adopting the above technical solution, the isolation ribs can reduce the vibration transmission of the two groups of drive units, avoid the mutual influence of pitch and horizontal adjustment actions, and at the same time, the cavities of different shapes formed by the isolation ribs and the components of different drive units are limited and accommodated.

[0016] A flip screen includes a display screen and the above-mentioned actuator. The display screen is movably arranged on a mounting shell. The actuator is arranged in the mounting shell and is linked to the display screen through a linkage mechanism. The linkage mechanism includes a first mechanism and a second mechanism. The first mechanism is used to convert the rotational motion of the first output shaft into a steering motion of the display screen on the horizontal plane of the mounting shell to adjust the horizontal display angle of the display screen. The second mechanism is used to convert the rotational motion of the second output shaft into a forward and backward pitching motion of the display screen on the mounting shell to unfold or retract the display screen.

[0017] By adopting the above-mentioned technical solution, the dual control of the horizontal steering adjustment and pitch flip function of the display screen is achieved by integrating the actuators, linkage mechanisms and mounting shells of the two drive units. This solution not only inherits the structural optimization and functional integration advantages of the actuator itself, but also further improves the overall performance and application scenario adaptability of the system through the innovative design of the linkage mechanism. First, the solution converts the two output axes of the actuator into the horizontal steering and vertical flipping actions of the display screen respectively through the first mechanism and the second mechanism in the linkage mechanism. Double-degree-of-freedom adjustment can be achieved without the traditional setting of two actuators, which significantly improves the functionality of the equipment and effectively avoids the problem of multiple actuators occupying the carrier space. At the same time, the shell of the traditional dual actuator is omitted, and only one shell is used, which effectively reduces the manufacturing cost of the product.

[0018] Furthermore, the mounting shell includes a base and a cover rotatably covered on the base, the actuator is assembled on the cover, the first mechanism includes a positioning column arranged at the axial center position of the base, the first output shaft is fixedly connected to the positioning column, and the display screen is movably arranged at the upper end of the cover.

[0019] By adopting the above technical solution, by assembling the actuator on the cover, when the first output shaft rotates around the positioning column, it will drive the entire cover to rotate on the base, and then drive the display screen on the cover to adjust the horizontal display angle.

[0020] Furthermore, rotating shafts are provided on both sides of the bottom of the display screen, which are rotatably connected to the cover plate through the rotating shafts. The second mechanism includes an output gear, a rotating gear and a linkage gear plate that links the two. The rotating gear is installed on the rotating shaft, and the output gear is installed on the second output shaft. The linkage gear plate slides linearly on the bottom of the cover plate, and its upper and lower end faces are respectively provided with racks that mesh with the output gear and the rotating gear.

[0021] By adopting the above technical solution, the tooth plate is arranged on the cover plate through linear sliding, and can slide linearly under the engagement of the output gear. During the sliding process, the tooth plate can drive the rotating gear to rotate around the rotating shaft through the rack, thereby realizing the forward and backward pitch movement of the display screen.

[0022] Furthermore, a receiving groove adapted to the size of the display screen is provided at the upper end of the cover plate, and shaft holes are provided at both sides of the bottom of the receiving groove at positions corresponding to the rotating shaft.

[0023] By adopting the above technical solution and the design of the accommodating groove, the integration degree between the display screen and the corresponding carrier after installation is improved.

[0024] Compared with the prior art, the advantages of the present invention are:

[0025] 1. By integrating the first drive unit and the second drive unit into the same housing and adopting a layout of two non-parallel, intersecting or skew output shafts, the product can use output shafts in different directions to replace traditional horizontal angle adjustment actuators and front and rear pitch and folding actuators, effectively improving the product's installation diversity, adaptability and practicality.

[0026] 2. In the present invention, the first output shaft and the second output shaft are designed to be non-parallel output shafts, such as being arranged perpendicularly or intersectingly in different planes, which can avoid the space waste problem caused by the parallel arrangement of the two output shafts. It not only maximizes the use of three-dimensional space, but also avoids the intersection of the motion trajectories of the two groups of drive units, thereby reducing the risk of mechanical interference.

[0036] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0037] Reference Figure 1An actuator is used for adjusting the angle of a display screen 5. It includes a shell 1 and a first drive unit 2 and a second drive unit 3 provided on the shell 1. The first drive unit 2 includes a first output shaft 23 and a first drive part that drives the first output shaft 23 to rotate. The second drive unit 3 includes a second output shaft 33 and a second drive part that drives the second output shaft 33 to rotate. The first output shaft 23 and the second output shaft 33 are arranged non-parallel to each other and intersect or are in different planes.

[0038] In this embodiment, by integrating the first drive unit 2 and the second drive unit 3 into the same housing 1 and adopting a layout of two non-parallel and intersecting or skew output shafts, the product can use output shafts in different directions to replace traditional horizontal angle adjustment actuators and front and rear pitch and folding actuators, effectively improving the product's installation diversity, adaptability and practicality.

[0039] In this embodiment, the first output shaft 23 and the second output shaft 33 are designed as non-parallel output shafts, such as being arranged perpendicularly or intersectingly in different planes, which can avoid the problem of space waste caused by the parallel arrangement of the two output shafts. It not only maximizes the use of three-dimensional space, but also avoids the intersection of the motion trajectories of the two groups of drive units, thereby reducing the risk of mechanical interference.

[0040] In this embodiment, the two drive units of the present application share one housing 1. Compared with the solution in which two independent actuators need to be respectively configured in different housings 1, this product effectively reduces the production cost of the product.

[0041] In this embodiment, refer to Figure 1 and 2 , (For the convenience of description, the coordinate system in the figure is Figure 2 The shell 1 is a rectangular parallelepiped as an example, with the x-axis direction being the length direction of the shell 1, the y-axis direction being the thickness of the shell 1, and the z-axis direction being the front-to-back width direction of the shell 1). The first output shaft 23 is arranged on the shell 1 along the y-axis direction, while the second output shaft 33 is arranged on the shell 1 along the x-axis direction. The positional relationship between the two is non-parallel, and they may be intersecting or skewed. Preferably, the first output shaft 23 and the second output shaft 33 are in a skewed and perpendicular intersecting relationship within the shell 1. This not only avoids the space waste problem caused by the parallel arrangement of the two output shafts, but also maximizes the use of the three-dimensional space, and avoids the intersection of the motion trajectories of the two sets of drive units, reducing the risk of mechanical interference. At the same time, the two output shafts distributed vertically and horizontally also correspond to the horizontal angle adjustment and the front-to-back pitch adjustment of the display screen 5, which facilitates the subsequent assembly between the first output shaft 23 and the second output shaft 33 and the display screen 5.

[0042] In this embodiment, refer to Figure 1 and 2The first driving part includes a first motor 21 and a first gear set 22. The first gear set 22 includes a first driving gear 221, a first duplex gear 222 and a first driven gear 224. The first motor 21 is horizontally arranged in the housing 1. The output shaft of the first motor 21 is connected to the first driving gear 221. The first output shaft 23 is arranged on the housing 1 to rotate vertically. The first duplex gear 222 is used to link the first driven gear 224 and the first driving gear 221. When the first motor 21 rotates, it drives the first driving gear 221 to rotate. The first driving gear 221 drives the first duplex gear 222 to rotate, and then drives the first output shaft 23 to rotate.

[0043] In this embodiment, a connecting shaft 223 is provided at the axis position of the first duplex gear 222, which is rotated inside the housing 1 through the first connecting shaft 223. The axis of the first duplex gear 222 and the axis of the first output shaft 23 are arranged in parallel, and both are arranged vertically on the housing 1. The axis of the first drive gear 221 is arranged horizontally. The first duplex gear 222 includes an upper gear and a lower gear, the lower gear of which is engaged with the first driven gear 224, and the upper gear of which is engaged with the first drive gear 221. The upper gear and the first drive gear 221 are both helical gears to facilitate the engagement between the vertically arranged first duplex gear 222 and the horizontally arranged first drive gear 221.

[0044] In this embodiment, refer to Figure 1 The second driving part includes a second motor 31 and a second gear set 32. The second gear set 32 includes a second driving gear 321, a second double gear 322 and a second driven gear 323. The second motor 31 is arranged adjacent to the first motor 21. The second driving gear 321 is mounted on the output end of the second motor 31. The second driven gear 323 is arranged on the second output shaft 33. The second double gear 322 is rotated by the rotating shaft 51 and is arranged on the housing 1. The second double gear 322 is between the second driven gear 323 and the second driving gear 321 for linking the two. The rotation of the second motor 31 drives the second driving gear 321 to rotate, and then drives the second output shaft 33 to rotate through the second double gear 322. The second output shaft 33 is arranged along the x-axis direction of the housing 1, and its corresponding axis is parallel to the axis of the second double gear 322 and the axis of the second output shaft 33, and is perpendicular to the axis of the first output shaft 23.

[0045] Based on the above embodiment, refer to Figure 2 The shell 1 includes a surface shell 11 and a bottom shell 12, which together form a cavity. The inner walls of the surface shell 11 and the bottom shell 12 are provided with isolation ribs 101. The isolation ribs 101 divide the cavity into multiple spaces so as to limit and accommodate related components such as the first motor 21, the second motor 31, the first gear set 22 and the second gear set 32 through different spaces.

[0046] In this embodiment, a second through hole 104 is opened on the side of the surface shell 11 and the bottom shell 12 at a position corresponding to the second output shaft 33, so that the second output shaft 33 can be connected to the external component, and a first through hole 103 is opened on the corresponding surface shell 11 and / or the bottom shell 12 at a position corresponding to the first output shaft 23, so that the first output shaft 23 can be connected to the external component.

[0047] Based on the above embodiment, a flip screen is provided, including a display screen 5, a mounting shell 4 and a linkage mechanism. Specifically, the display screen 5 is movably arranged on the mounting shell 4, the actuator is arranged in the mounting shell 4, and is linked to the display screen 5 through a linkage mechanism. The linkage mechanism includes a first mechanism and a second mechanism 44. The first mechanism is used to convert the rotational motion of the first output shaft 23 into a steering motion of the display screen 5 on the horizontal plane of the mounting shell 4 to adjust the horizontal display angle of the display screen 5. The second mechanism 44 is used to convert the rotational motion of the second output shaft 33 into a forward and backward pitching motion of the display screen 5 on the mounting shell 4 to unfold or retract the display screen 5.

[0048] Through the above-mentioned institutional settings, refer to Figure 3 , realizing a single actuator, can solve the dual control of the horizontal steering adjustment and pitch flip function of the display screen 5. This solution not only inherits the structural optimization and functional integration advantages of the actuator itself, but also further improves the overall performance and application scenario adaptability of the system through the innovative design of the linkage mechanism. First, this solution converts the two output shafts of the actuator into the horizontal steering and vertical flip actions of the display screen 5 respectively through the first mechanism and the second mechanism 44 in the linkage mechanism. Double-degree-of-freedom adjustment can be achieved without the traditional setting of two actuators, which significantly improves the functionality of the equipment and effectively avoids the problem of multiple actuators occupying the carrier space. At the same time, the shell 1 of the traditional dual actuator is omitted, and only one shell 1 is used, which effectively reduces the product manufacturing cost and the installation space occupied by the corresponding carrier.

[0049] In this embodiment, refer to Figure 3 The mounting shell 4 includes a base 42 and a cover 41 rotatably covered on the base 42. The actuator is assembled on the cover 41. Taking the base 42 as a cylindrical example, the cover 41 is circular, and the base 42 is hollow to accommodate the actuator. The display screen 5 is rotatably arranged on the upper end of the cover 41. The first mechanism includes a positioning column 43 provided at the axial center position of the base 42. The positioning column 43 is connected to the first output shaft 23 by a key. In this way, when the actuator drives the first output shaft 23 to rotate around the positioning column 43, it will drive the entire cover 41 to rotate on the base 42, thereby driving the display screen 5 on the cover 41 to adjust the horizontal display angle, thereby realizing the adjustment of the horizontal angle of the display screen 5.

[0050] In this embodiment, a accommodating groove 411 is provided at the upper end of the cover plate 41, and rotating shafts 51 are provided on both sides of the bottom of the display screen 5. Correspondingly, rotating holes 412 are opened on both sides of the inner wall of the accommodating groove 411. The display screen 5 is rotated in the rotating hole 412 through the rotating shaft 51. In this way, the display screen 5 can be folded back and forth and pitched along the Y-axis with the rotating shaft 51 as the rotation axis into the accommodating groove 411, thereby realizing the storage function and the unfolding function of the display screen 5.

[0051] Reference Figure 3 The second mechanism 44 comprises an output gear 441, a rotating gear 445 and a linkage gear plate 442 that links the two. The rotating gear 445 is mounted on the rotating shaft 51. The output gear 441 is located on one side of the housing 1 and is mounted on the second output shaft 33. The linkage gear plate 442 slides linearly on the bottom of the cover 41. The upper and lower end surfaces of the linkage gear plate 442 are respectively provided with racks that mesh with the output gear 441 and the rotating gear 445. For the sake of convenience, the rack linked to the rotating gear 445 is referred to as an upper rack 442a, the rack at the lower end of the linkage gear plate 442 is referred to as a lower rack 442b, and the rack linked to the output gear 441 is referred to as a lower rack 442b. When the second output shaft 33 drives the driving gear to rotate, it meshes with the lower rack 442b and thereby drives the linkage gear plate 442 to linearly displace. During the movement, it meshes with the rotating gear 445 through the upper rack 442a, thereby driving the display screen 5 to flip, fold or unfold back and forth with the rotating shaft 51 as the rotation axis.

[0052] In this embodiment, the linkage gear plate 442 serves as a linkage component between the output gear 441 and the rotating gear 445. Its function is to transmit the rotational motion of the output gear 441 to the rotating gear 445, thereby driving the rotating shaft 51 to rotate, and then achieving the purpose of folding the display screen 5 forward and backward. It can be imagined that the linkage gear plate 442 can also be a gear, a transmission belt or other components that can achieve the above functions. The linkage gear plate 442 is not limited to a literal toothed plate structure.

[0053] In this embodiment, taking the linkage tooth plate 442 as an elongated strip as an example, a mounting bracket 443 is provided at the bottom of the cover plate 41, and a through hole adapted to the size of the linkage tooth plate 442 is formed inside the mounting bracket 443. The linkage rack can be slidably arranged in the through hole, thereby achieving the purpose of linear sliding of the linkage rack on the cover plate 41.

[0054] In this embodiment, the function of the mounting bracket 443 is to guide the linear sliding of the linkage rack in the mounting shell 4. Therefore, the specific structure of the mounting bracket 443 can be varied and is not limited to the L-shaped structure shown in the drawings.

[0055] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
