Description

Technical Field

[0001] This utility model relates to the field of display screen angle adjustment technology, and in particular to an actuator and a flip screen. Background Technology

[0002] In the field of smart cockpits, when an in-vehicle display screen is folded, an actuator is generally used to drive the display screen to rotate. The output shaft on the actuator is connected to the display screen, which in turn drives the display screen to rotate horizontally or tilt back and forth on the corresponding carrier, thereby achieving the adjustment of the display screen angle and unfolding / folding.

[0003] However, the current actuators have relatively limited functions. For horizontal angle adjustment or forward and backward folding, it is necessary to select an actuator with a specific angle output shaft. The functions are relatively limited and the adaptability is poor. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide an actuator and a flip screen, which solves the problem that the existing actuators have relatively simple functions.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an actuator, including a housing and a first drive unit and a second drive unit disposed on the housing. The first drive unit includes a first output shaft and a first drive part for driving the first output shaft to rotate. The second drive unit includes a second output shaft and a second drive part for driving the second output shaft to rotate. The first output shaft and the second output shaft are not parallel and are intersecting or on opposite sides.

[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 skewed perpendicular relationship within the housing.

[0007] By adopting the above technical solution, the non-plane vertical or intersecting layout can avoid the 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 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 front and back tilt adjustment of the display screen.

[0008] Furthermore, the first drive section includes a first motor and a first gear set. The first gear set includes a first drive gear, a first double gear, and a first driven gear. The first drive 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. The first double gear is used to link the first driven gear and the first drive gear.

[0009] By adopting the above technical solutions, 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 drive section includes a second motor and a second gear set. The second gear set includes a second drive gear, a second double gear, and a second driven gear. The second drive 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. The second double gear is used to drive the second driven gear and the second drive gear together.

[0011] By adopting the above technical solution, the structure is similar to that of the first drive part, which facilitates mass production and reduces manufacturing costs. At the same time, the same gear set design ensures that the transmission characteristics of the two drive units are consistent and improves synchronization.

[0012] Furthermore, the axial direction of the second drive gear is parallel to the axial direction of the second double gear, while the axial direction of the first drive gear is perpendicular to the axial direction of the first double 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 double 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 double gear, and the two are linked by helical gears. In this way, the horizontally placed first motor can be linked with the vertically arranged first output shaft through the first double gear.

[0014] Furthermore, the housing includes a front shell and a bottom shell, which together form a cavity. The inner walls of both 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 rib can reduce the vibration transmission of the two sets of drive units, avoid the mutual influence of pitch and horizontal adjustment movements, and at the same time limit and accommodate the different shaped cavities formed by the isolation rib and the components of different drive units.

[0016] A flip screen includes a display screen and the aforementioned actuator. The display screen is movably mounted on a mounting housing, and the actuator is located inside the mounting housing and is linked to the display screen via 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 turning motion of the display screen on the horizontal plane of the mounting housing 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 pitching motion of the display screen on the mounting housing to unfold or retract the display screen.

[0017] By adopting the above technical solution, and by integrating the actuators, linkage mechanisms, and mounting housing of two drive units, dual control of the display screen's horizontal steering adjustment and pitch tilting functions is achieved. 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, through the first and second mechanisms in the linkage mechanism, the two output shafts of the actuator are converted into the horizontal steering and vertical tilting actions of the display screen, respectively. Dual-degree-of-freedom adjustment can be achieved without the traditional setting of two actuators, which significantly improves the functionality of the equipment, effectively avoids the problem of multiple actuators occupying carrier space, and at the same time, it eliminates the traditional dual-actuator housing, requiring only one housing, effectively reducing product manufacturing costs.

[0018] Furthermore, the mounting housing includes a base and a cover plate that rotates and fits onto the base. The actuator is mounted on the cover plate. The first mechanism includes a positioning post located at the center of the base axis, a first output shaft that is fixedly connected to the positioning post, and a display screen that is movably mounted on the upper end of the cover plate.

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

[0020] Furthermore, the bottom two sides of the display screen are provided with rotating shafts, which are rotatably connected to the cover plate. The second mechanism includes an output gear, a rotating gear, and a linkage gear plate that links the two. The rotating gear is mounted on the rotating shaft, the output gear is mounted on the second output shaft, and the linkage gear plate slides linearly on the bottom of the cover plate. 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 toothed plate is linearly slidably mounted on the cover plate and can slide linearly under the meshing of the output gear. During the sliding process, the toothed plate can drive the rotating gear to rotate around the axis through the rack, thereby realizing the forward and backward tilting action of the display screen.

[0022] Furthermore, the upper part of the cover plate is provided with a receiving groove that matches the size of the display screen, and the bottom sides of the receiving groove are provided with shaft holes corresponding to the position of the pivot.

[0023] By adopting the above technical solution, the design of the receiving slot facilitates the improvement of the integration between the display screen and the corresponding carrier after installation.

[0024] Compared with the prior art, the advantages of this utility model are:

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

[0026] 2. In this utility model, the first output shaft and the second output shaft are designed to be non-parallel output shafts, such as being arranged in opposite directions, perpendicular or intersecting, which can avoid the space waste caused by the parallel arrangement of the two output shafts. This 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.

[0035] 5 displays, 51 hinges. Detailed Implementation

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

[0037] Reference Figure 1An actuator for adjusting the angle of a display screen 5 includes a housing 1 and a first drive unit 2 and a second drive unit 3 disposed on the housing 1. The first drive unit 2 includes a first output shaft 23 and a first drive portion for driving the first output shaft 23 to rotate. The second drive unit 3 includes a second output shaft 33 and a second drive portion for driving the second output shaft 33 to rotate. The first output shaft 23 and the second output shaft 33 are not parallel and are intersecting or on opposite sides.

[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 output shafts that are non-parallel and intersecting or out of plane, the product can use output shafts in different directions to replace traditional actuators for horizontal angle adjustment and actuators for pitch and folding, 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 in opposite directions perpendicularly or intersectingly. This can avoid the space waste caused by the parallel arrangement of the two output shafts, not only maximizing the use of three-dimensional space, but also avoiding the intersection of the motion trajectories of the two sets of drive units, thus reducing the risk of mechanical interference.

[0040] In this embodiment, the two drive units of this application share a housing 1, which is different from the solution where two independent actuators need to be configured in different housings 1. This effectively reduces the production cost of the product.

[0041] In this embodiment, refer to Figure 1 and 2 (For ease of description, the coordinate system in the figure is based on...) Figure 2 Taking the housing 1 as a cuboid (x-axis, y-axis, z-axis, and z-axis directions), the first output shaft 23 is positioned on the housing 1 along the y-axis, while the second output shaft 33 is positioned on the housing 1 along the x-axis. The two output shafts are not parallel; they can be intersecting or non-parallel. Preferably, the first output shaft 23 and the second output shaft 33 are perpendicularly intersecting non-parallel within the housing 1. This not only avoids the space wastage caused by the parallel arrangement of the two output shafts and 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 vertically and horizontally distributed output shafts also correspond to the horizontal angle adjustment and front-back tilt adjustment of the display screen 5, facilitating 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 double 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 rotatably mounted on the housing 1 along the vertical direction. The first double 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 double gear 222 to rotate, which in turn drives the first output shaft 23 to rotate.

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

[0044] In this embodiment, refer to Figure 1 The second drive section includes a second motor 31 and a second gear set 32. The second gear set 32 ​​includes a second drive gear 321, a second double gear 322, and a second driven gear 323. The second motor 31 is positioned adjacent to the first motor 21. The second drive gear 321 is mounted on the output end of the second motor 31. The second driven gear 323 is mounted on the second output shaft 33. The second double gear 322 is rotatably mounted on the housing 1 via a rotating shaft 51. The second double gear 322 is positioned between the second driven gear 323 and the second drive gear 321 to link the two. The rotation of the second motor 31 drives the second drive gear 321 to rotate, which in turn drives the second output shaft 33 to rotate via the second double gear 322. The second output shaft 33 is positioned along the x-axis of the housing 1, and its axis is parallel to the axis of the second double gear 322 and the axis of the second output shaft 33, respectively, and perpendicular to the axis of the first output shaft 23.

[0045] Based on the above embodiments, referring to Figure 2 The housing 1 includes a front shell 11 and a bottom shell 12, which together form a cavity. The inner walls of the front shell 11 and the bottom shell 12 are provided with isolation ribs 101, which divide the cavity into multiple spaces 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, the sides of the front shell 11 and the bottom shell 12 are provided with second through holes 104 corresponding to the position of the second output shaft 33, so as to facilitate the connection of the second output shaft 33 with external components. The corresponding front shell 11 and / or bottom shell 12 are provided with first through holes 103 corresponding to the position of the first output shaft 23, so as to facilitate the connection of the first output shaft 23 with external components.

[0047] Based on the above embodiments, 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 mounted on the mounting shell 4, and the actuator is located inside the mounting shell 4 and is linked to the display screen 5 through the 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 the turning motion of the display screen 5 on the horizontal plane of the mounting shell 4, so as 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 the pitching motion of the display screen 5 on the mounting shell 4, so as to unfold or retract the display screen 5.

[0048] Based on the above institutional setup, referring to Figure 3 This solution enables a single actuator to control both the horizontal rotation and pitch tilt functions of the display screen 5. It not only inherits the structural optimization and functional integration advantages of the actuator itself, but also further enhances the overall system performance and application scenario adaptability through innovative design of the linkage mechanism. Firstly, the solution uses the first and second mechanisms 44 in the linkage mechanism to convert the two output shafts of the actuator into the horizontal rotation and vertical tilt movements of the display screen 5, respectively. This eliminates the need for two actuators, achieving dual-degree-of-freedom adjustment, significantly improving the device's functionality and effectively avoiding the problem of multiple actuators occupying space on the carrier. Simultaneously, it eliminates the traditional dual-actuator housing 1, requiring only one housing 1, effectively reducing product manufacturing costs and the corresponding space occupied by the carrier installation.

[0049] In this embodiment, refer to Figure 3 The mounting housing 4 includes a base 42 and a cover plate 41 that rotates and fits onto the base 42. The actuator is mounted on the cover plate 41. Taking the base 42 as cylindrical as an example, the cover plate 41 is circular. The base 42 is hollow inside to accommodate the actuator. The display screen 5 is rotatably mounted on the upper end of the cover plate 41. The first mechanism includes a positioning post 43 located at the axial position of the base 42. The positioning post 43 is connected to the first output shaft 23 by a key. When the actuator drives the first output shaft 23 to rotate around the positioning post 43, it will drive the entire cover plate 41 to rotate on the base 42, thereby driving the display screen 5 on the cover plate 41 to adjust the horizontal display angle, thus realizing the adjustment of the horizontal angle of the display screen 5.

[0050] In this embodiment, the upper end of the cover plate 41 is provided with a receiving groove 411, and the bottom sides of the display screen 5 are provided with rotating shafts 51. The inner walls of the corresponding receiving grooves 411 are provided with rotating holes 412. The display screen 5 is rotated into the rotating holes 412 through the rotating shafts 51. In this way, the display screen 5 can be folded back and forth into the receiving groove 411 with the rotating shafts 51 as the rotation axis Y, realizing the function of storing and unfolding the display screen 5.

[0051] Reference Figure 3 As a specific embodiment of the second mechanism 44, the second mechanism 44 includes 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, and 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 plate 41. Its upper and lower end faces are respectively provided with racks that mesh with the output gear 441 and the rotating gear 445. For ease of description, the rack that is linked with the rotating gear 445 is called the upper rack 442a, and the rack at the lower end of the linkage gear plate 442 that is linked with the output gear 441 is called the lower rack 442b. When the second output shaft 33 drives the drive gear to rotate, it meshes with the lower rack 442b, thereby driving the linkage gear plate 442 to move linearly. During the movement, it meshes with the rotating gear 445 through the upper rack 442a, thereby driving the display screen 5 to flip and fold or unfold around the rotating shaft 51 as the axis of rotation.

[0052] In this embodiment, the linkage tooth 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 thus achieving the purpose of tilting and folding the display screen 5. It is conceivable that the linkage tooth plate 442 can also be a gear, a transmission belt, or other components that can achieve the above functions. The linkage tooth plate 442 is not limited to the toothed structure in the literal sense.

[0053] In this embodiment, taking the linkage toothed plate 442 as an example of being long and narrow, the bottom of its cover plate 41 is provided with a mounting bracket 443. The mounting bracket 443 has a through hole that matches the size of the linkage toothed plate 442. The linkage toothed plate can be slidably disposed in the through hole, thereby achieving the purpose of linear sliding of the linkage toothed plate on the cover plate 41.

[0054] In this embodiment, the mounting bracket 443 is used to guide the linear sliding of the linkage rack within the mounting housing 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 attached 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 can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
