Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This disclosure claims priority to Chinese Patent Application No. 2023100923237, filed with the State Intellectual Property Office of China on January 30, 2023, entitled "ADJUSTING DEVICE FOR ONBOARD SCREEN, ONBOARD SCREEN ASSEMBLY AND VEHICLE," which is incorporated herein by reference in its entirety.

[0002] The present disclosure relates to the field of automotive technology, and in particular to an adjustment device for an on-board screen, an on-board screen assembly, and a vehicle. [Background technology]

[0003] The left and right swivel function of the automobile central control screen not only improves the driver's comfort and driving safety when using the screen, but also provides the front seat passenger with a comfortable viewing angle of the screen, which can greatly improve the human-machine interaction performance. In the prior art, due to the application of a large screen and the limitations of the style of the instrument panel, the field of view is greatly obstructed when swivels toward the driver's side, and the gap between the screen and the vehicle combination switch and steering wheel is small when swivels toward the front seat passenger, which may cause interference.

[0028] DETAILED DESCRIPTION OF THE DRAWINGS The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings, which are illustrative only.

[0029] The following describes an adjustment device 50 for an on-board screen according to an embodiment of the present disclosure with reference to Figures 1 to 6. Furthermore, the present disclosure also proposes an on-board screen assembly 100 and a vehicle equipped with the above-mentioned adjustment device 50 for an on-board screen.

[0030] 1 to 6, an adjustment device 50 for an on-board screen includes a screen bracket 2 and a multi-link mechanism 10. Among them, the screen bracket 2 is configurable to mount an on-board screen 6.

[0031] The multi-link mechanism 10 is movably connected to the screen bracket 2, and the multi-link mechanism 10 has an asymmetric structure. The multi-link mechanism 10 is configured to deflect and translate the screen bracket 2 toward the driver's side or toward the front passenger's side to achieve adjustment of the on-board screen 6, and the screen bracket 2 moves away from the driver's side during the adjustment process.

[0032] Specifically, the multi-link mechanism 10 has an asymmetric structure. When adjusting the on-board screen 6, the multi-link mechanism 10 can deflect and translate the screen bracket 2 toward the driver's side or toward the front passenger's side, with the screen bracket 2 moving away from the driver's side during the adjustment process. In this way, the screen bracket 2 can avoid the wiper switch, combination light switch, etc. on the steering wheel side when deflecting toward the driver's side or the front passenger's side. This therefore solves the problem of large field of view obstruction when turning toward the driver's side, and at the same time, the problem of small gaps between the on-board screen 6 and the combination switch and steering wheel when turning toward the front passenger's side.

[0033] It should be noted that the multi-link mechanism 10 translates and deflects the screen bracket 2, which means that the screen bracket 2 can translate along one direction and deflect toward another direction at the same time. In one embodiment of the present disclosure, considering the X-axis direction and the Y-axis direction in the three-axis coordinate system of the vehicle as references, the multi-link mechanism 10 can translate the screen bracket 2 along the Y-axis direction and simultaneously deflect it in the X-axis direction toward the driver's side or the front passenger's side so that the screen bracket 2 deflects and translates toward the driver's side or the front passenger's side, thereby achieving adjustment of the on-board screen 6.

[0034] Among these, the X-axis direction is the width direction of the vehicle, that is, the left-right direction, and the Y-axis direction is the length direction of the vehicle, that is, the front-rear direction.

[0035] Therefore, the motion configuration of the multi-link mechanism 10 is asymmetric, which allows the on-board screen to pivot toward the driver's side while shifting its position toward the front passenger's side, or pivot toward the front passenger's side while shifting its position toward the front passenger's side. In this way, the motion configuration of the multi-link mechanism 10 effectively solves the problem of significant obstruction of the field of view when pivoting toward the driver's side, and at the same time, the problem of small gaps between the screen and the combination switch and steering wheel when pivoting toward the front passenger's side. Compared to existing mechanisms that achieve screen deflection by stacking multiple unidirectional movements, the motion mechanism of the on-board screen adjustment device 50 of the present disclosure is relatively simple and is not easily restricted by the shape of an instrument panel, etc.

[0036] Specifically, the multi-link mechanism 10 includes a first link mechanism 3 and a second link mechanism 4, which are asymmetrically positioned and connected to the screen bracket 2. The first link mechanism 3 and the second link mechanism 4 have different movement strokes to adjust the on-board screen 6. As shown in FIG. 2 , the first link mechanism 3 and the second link mechanism 4 are designed to have asymmetric structures. The curved structure of the second link mechanism 4 allows the screen bracket 2 to move away from the driver's side during the adjustment process. Furthermore, the different movement strokes of the first link mechanism 3 and the second link mechanism 4 allow the first link mechanism 3 and the second link mechanism 4 to deflect and translate the screen bracket 2 toward the driver's side or toward the front passenger's side.

[0037] Furthermore, the first link mechanism 3 includes a first link 31, one end of which is movably connected to one side of the screen bracket 2. The second link mechanism 4 includes a second link 41 and a third link 5, one end of which is movably connected to the other side of the screen bracket 2, and the third link 5 is movably connected between the first link 31 and the second link 41. In this way, the third link 5, the first link 31, the second link 41, and the screen bracket 2 form a multi-link mechanism. The third link 5 enables the first link 31 and the second link 41 to move the screen bracket 2 along a unique trajectory, ensuring the movement stability of the multi-link mechanism.

[0038] Furthermore, the movement strokes of the first link 31 and the second link 41 are different. That is, by controlling the movement strokes of the first link 31 and the second link 41 to be different to generate the difference in the strokes, the screen bracket 2 can be driven to deflect and translate toward the driver's side or toward the front seat passenger's side.

[0039] Specifically, in the embodiment of the present disclosure, the first link 31 and the second link 41 can be disposed on the left and right sides of the screen bracket 2, respectively. The first link 31 can perform translational movement along the Y-axis direction, while the second link 41 can perform translational movement along the Y-axis direction and, at the same time, deflection movement along one side (driver's side or front passenger's side) in the X-axis direction. Based on the above asymmetrical movement of the first link 31 and the second link 41, the screen bracket 2 can move away from the driver's side during the adjustment process. Specifically, when pivoting toward the driver's side, the screen bracket 2 shifts its position toward the front passenger's side, and when pivoting toward the front passenger's side, the screen bracket 2 also shifts its position toward the front passenger's side. In this way, the screen bracket 2 effectively solves the problem of large obstruction of the field of view when turning towards the driver's side, and at the same time solves the problem of small gaps between the screen and the combination switch and the steering wheel when turning towards the front passenger's side, thereby achieving the deflection of the on-board screen 6 towards the driver's side or the front passenger's side.

[0040] Of course, the first link 31 and the second link 41 can also be disposed on the upper and lower sides, respectively, of the screen bracket 2. When the first drive assembly 32 moves the first link 31 and the second drive assembly 42 moves the second link 41, the on-board screen 6 can also be deflected upward or downward.

[0041] Furthermore, the first link mechanism 3 includes a first drive assembly 32. The first drive assembly 32 causes the first link 31 to perform translational movement. The second link mechanism 4 further includes a second drive assembly 42. The second drive assembly 42 causes the second link 41 to perform deflection and translational movement toward the front passenger side such that the movement stroke of the first link 31 is different from the movement stroke of the second link 41. It may be understood that one side of the screen bracket 2 is movably connected to one end of the first link 31, and the first drive assembly 32 causes the first link 31 to perform translational movement. Correspondingly, the other side of the screen bracket 2 is movably connected to one end of the second link 41, and the second drive assembly 42 causes the second link 41 to perform translational movement and deflection toward the front passenger side.

[0042] Furthermore, the first link 31 can translate forward, and the second link 41 can translate forward and deflect left / right. The movement strokes of the first link 31 and the second link 41 can be adjusted through the output speeds of the first drive assembly 32 and the second drive assembly 42 so that there is a difference in the speeds of the first link 31 and the second link 41. In this way, the strokes of the first link 31 and the second link 41 are different within the same operating time. The difference in the strokes provided by the first link 31 and the second link 41 can be reflected in the on-board screen 6 through the screen bracket 2, thereby achieving deflection of the on-board screen 6 toward the driver's side or the front passenger's side.

[0043] It should be noted that the forward movement mentioned above is movement towards the rear of the vehicle in the Y axis direction.

[0044] Optionally, in the embodiment of the present disclosure, a connecting bolt 7 is provided at one end of each of the first link 31 and the second link 41. As shown in FIG. 3 , the first link 31 and the second link 41 are hinged to both sides of the screen bracket 2 through the connecting bolt 7.

[0045] For example, when the on-board screen 6 needs to be deflected toward the driver's side, the first drive assembly 32 on the side closer to the driver moves the first link 31 a relatively short distance, while the second drive assembly 42 on the side farther from the driver moves the second link 41 a relatively long distance. This allows the screen bracket 2 and the on-board screen 6 to deflect toward the driver's side, as shown in FIG. 5. Similarly, when the on-board screen 6 needs to be deflected toward the front passenger's side, the second drive assembly 42 on the side closer to the front passenger moves the second link 41 a relatively short distance, while the first drive assembly 32 on the side farther from the front passenger moves the first link 31 a relatively long distance. This allows the screen bracket 2 and the on-board screen 6 to deflect toward the front passenger's side, as shown in FIG. 4. Furthermore, since the first link 31 can translate toward the front passenger side, and the second link 41 can translate and deflect toward the front passenger side, the screen bracket 2 can always move away from the driver's side during the adjustment process, which solves the problem of large obstruction of the field of view when turning toward the driver's side, and the problem of small gaps between the screen and the combination switch and steering wheel when turning toward the front passenger side.

[0046] Compared with adjustment assemblies that rotate around a fixed central axis or move in a straight line, and achieve increased movement by stacking multiple unidirectional motions, in the present disclosure, deflection is achieved through a virtual central axis formed by the first link 31 and the second link 41. There is no need to stack multiple unidirectional motions, which greatly simplifies the movement structure and facilitates fabrication and use.

[0047] In some embodiments, the first drive assembly 32 includes a first drive member 321, a first transmission member 322, and a second transmission member 323. The first drive member 321 is in transmission connection with the first transmission member 322. The second transmission member 323 is disposed on the first transmission member 322 and is movable relative to the first transmission member 322. The second transmission member 323 is movably connected to the other end of the first link 31.

[0048] In this manner, the first driving member 321 is in transmission connection with the first transmission member 322, and the second transmission member 323 is disposed on the first transmission member 322. When the first driving member 321 rotates the first transmission member 322, the second transmission member 323 can move on the first transmission member 322, thereby translating the first link 31 along the Y-axis.

[0049] Specifically, when the first driving member 321 rotates the first transmission member 322, the output shaft of the first driving member 321 rotates in cooperation with the first transmission member 322. Then, the second transmission member 323 moves on the first transmission member 322. At this time, the second transmission member 323 translates the first link 31, the screen bracket 2, and one side of the on-board screen 6 along the Y axis.

[0050] Furthermore, the second drive assembly 42 includes a second drive member 421, a third transmission member 422, and a fourth transmission member 423. The second drive member 421 is transmission-connected to the third transmission member 422. The fourth transmission member 423 is disposed on the third transmission member 422 and is movable relative to the third transmission member 422. The fourth transmission member 423 is movably connected to the other end of the second link 41. Similar to the principle of the first drive assembly 32, when driven by the second drive member 421, the fourth transmission member 423 moves on the third transmission member 422. This causes the second link 41, the screen bracket 2, and the other side of the on-board screen 6 to translate along the Y axis and, at the same time, deflect along the X axis toward the front seat passenger.

[0051] Specifically, as shown in FIG. 3 , the first transmission member 322 is a first lead screw, the second transmission member 323 is a first lead screw nut, the third transmission member 422 is a second lead screw, and the fourth transmission member 423 is a second lead screw nut. In this manner, the first drive member 321 may be a first motor. The output shaft of the motor is in driving connection with the first lead screw, and the first lead screw nut is helically engaged with the first lead screw. When the first motor is started, the first lead screw rotates in position, and the first lead screw nut rotates helically on the first lead screw, thereby translating the first link 31, the screen bracket 2, and one side of the on-board screen 6. The third transmission member 422 and the fourth transmission member 423 are disposed symmetrically on both sides of the screen bracket 2 relative to the first transmission member 322 and the second transmission member 323. Similarly, the second drive member 421 translates and deflects the second link 41, the screen bracket 2, and the other side of the on-board screen 6.

[0052] Furthermore, one end of the first lead screw nut is connected to the connecting bolt 7 at one end of the first link 31. Similarly, one end of the second lead screw nut is connected to the connecting bolt 7 at one end of the second link 41.

[0053] Of course, the first drive assembly 32 may also include only the first drive member 321 and the first transmission member 322, with the first transmission member 322 movably connected to the other end of the first link 31. When the first drive member 321 drives the first transmission member 322, the first transmission member 322 can move instead of rotating in place, thereby translating the first link 31. The second drive assembly 42 may also include only the second drive member 421 and the third transmission member 422, with the third transmission member 422 movably connected to the other end of the second link 41. When the second drive member 421 drives the third transmission member 422, the screen bracket 2 and the onboard screen 6 are deflected toward the driver's side or the front passenger's side.

[0054] The central axis of the second lead screw is biased toward the front passenger side, while the central axis of the first lead screw is parallel to the central axis formed between the front passenger and the driver. In this way, the first and second lead screws are not arranged parallel to each other, and the central axis of the second lead screw is biased toward the front passenger side. Therefore, the on-board screen 6 can be shifted toward the front passenger side while pivoting toward the driver's side, or the on-board screen 6 can be shifted toward the front passenger side while pivoting toward the front passenger side. This not only solves the problem of significant obstruction of the field of view when the on-board screen is pivoted toward the driver's side, but also solves the problem of small gaps between the screen and the combination switch and steering wheel when the on-board screen is pivoted toward the front passenger side.

[0055] Furthermore, the direction of movement of the first lead screw nut on the first lead screw and the direction of movement of the second lead screw nut on the second lead screw can be different so that the final position of the movement of the first lead screw nut and the final position of the movement of the second lead screw nut are not in the same X-axis direction. In this way, even if the output speeds of the first drive member 321 and the second drive member 421 are the same, by changing the extension directions of the first lead screw and the second lead screw, the first link 31 and the second link 41 can also deflect the screen bracket 2 and the on-board screen 6. Of course, the output speeds of the first drive member 321 and the second drive member 421 can also be combined to allow the first link 31 and the second link 41 to quickly deflect the screen bracket 2.

[0056] More specifically, the first lead screw is disposed closer to the driver and extends parallel to the Y-axis direction (i.e., the front-to-rear direction) of the vehicle, while the second lead screw is disposed closer to the front passenger and extends in a direction biased toward the front passenger, forming a specific angle with the first lead screw. In this way, the first lead screw and the second lead screw form an asymmetric structure, allowing the on-board screen 6 to pivot toward the driver's side while shifting its position toward the front passenger's side, and vice versa.

[0057] In some embodiments, one end of the third link 5 is movably connected to a position between the two ends of the second link 41 to form a triangle with the line connecting the two ends of the second link 41, and the other end of the third link 5 is movably connected to a position between the two ends of the first link 31 to form a straight line with the line connecting the two ends of the first link 31. The second lead screw on one side of the second link 41 is designed to be deflected at a specific angle, so that the line connecting the two ends of the second link 41 and one end of the third link 5 forms a triangle, which promotes deflection of the second link 41 and the third link 5 toward the driver's side or the front passenger's side.

[0058] Specifically, the first link 31 is a straight link, the second link 41 is an irregularly shaped link because the position where it connects to the third link 5 is bent toward the third link 5, and the third link 5 is an arc-shaped link. In this way, designing the second link 41 as an irregularly shaped link structure is not only beneficial for moving the screen bracket 2 away from the driver's side during the adjustment process, but also beneficial for adjusting the on-board screen 6 to be deflected toward the driver's side.

[0059] In one embodiment of the present disclosure, the first link 31 can be separated into upper and lower castings for machining, and then connected into one piece by three hinge bolts. The first link 31 is connected to the hinge bolt through two bushings 8, which can reduce wear. The front end of the first link 31 is connected to one side of the screen bracket 2 through the hinge bolt and two bushings 8. The middle part of the first link 31 is connected to the third link 5 through the hinge bolt and two bushings 8, and the third link 5 is connected to the second link 41 through the hinge bolt and two bushings 8.

[0060] In some embodiments, the adjustment device 50 for the on-board screen further includes a control device 304. The control device 304 is electrically connected to the first drive assembly 32 and the second drive assembly 42 to control starting and stopping of the first drive assembly 32 and the second drive assembly 42, respectively. The control device is specifically configured to control the first drive assembly 32 and the second drive assembly 42 to rotate at different speeds so that the movement stroke of the first link 31 is different from the movement stroke of the second link 41. In other words, by controlling the different rotation speeds of the first drive assembly 32 and the second drive assembly 42, the movement stroke of the first link 31 can be made different from the movement stroke of the second link 41 under the same time condition, thereby achieving adjustment of the on-board screen 6.

[0061] Specifically, when the control device 304 receives a signal instructing deflection toward the front passenger side, the rotational speed of the first drive member 321 is controlled to be higher than the rotational speed of the second drive member 421. After being powered on for a certain period of time, the first lead screw nut driven by the first drive member 321 moves to the end position of the first lead screw and contacts the signal switch, turning off the power to the first drive member 321 and the second drive member 421. Meanwhile, the second lead screw nut driven by the second drive member 421 moves a distance shorter than the distance of the first lead screw nut. Under the pressure of the second lead screw nut and the restraint of the third link 5, the second link 41 creates an inward swinging motion, which is transmitted to the screen bracket 2. The first link 31 also creates a forward pushing motion under the pressure of the first lead screw nut and the restraint of the third link 5, which is transmitted to the screen bracket 2. As shown in Fig. 4, the screen bracket 2 connected to the on-board screen 6 pivots left and moves forward under the combined action of the first link 31 and the second link 41, thereby achieving leftward deflection of the on-board screen 6. Correspondingly, when the control device 304 receives a signal instructing deflection toward the driver's side, the rotational speed of the second driving member 421 becomes higher than that of the first driving member 321, causing the second lead screw nut to move a longer distance than the distance of the first lead screw nut. As shown in Fig. 5, the difference in travel is reflected to the on-board screen 6 via the screen bracket 2, thereby achieving rightward deflection of the on-board screen 6.

[0062] As shown in Figure 4, the stroke of the second lead screw nut is approximately 36 mm, and the stroke of the first lead screw nut is approximately 64 mm. The entire screen rotates approximately 15° toward the front seat passenger side under the restraint of the third link 5.

[0063] As shown in Figure 5, the stroke of the second lead screw nut is approximately 58 mm, and the stroke of the first lead screw nut is approximately 38 mm. The entire screen rotates approximately 15° toward the driver's side under the restraint of the third link 5.

[0064] Therefore, the lateral pivot angle of the on-board screen 6 can be controlled under the constraint of the third link 5 by adjusting the stroke of the second lead screw nut on the second lead screw and the stroke of the first lead screw nut on the first lead screw.

[0065] The travel time for the screen to pivot toward the driver's side and the travel time for the screen to pivot toward the front-seat passenger's side can both be set as fixed values, for example, approximately 2 seconds. To achieve different movement strokes of the first and second lead screw nuts within the same time, it is necessary to adjust the travel speeds of the second and first lead screw nuts. Because the first and second lead screw nuts are threadedly engaged with the first and second lead screws, this adjustment depends on the rotation speeds of the first and second lead screws driven by the first and second drive members 321 and 421. The first and second drive members 321 and 421 may be variable-speed motors. By adjusting the rotation speeds of the motors through voltage adjustment, lateral rotation of the on-board screen 6 toward the driver or front-seat passenger can be achieved.

[0066] In some embodiments, the angle at which the screen bracket 2 is deflected toward the driver's side or the front-seat passenger's side is α, and α satisfies the relationship of 0°<α≦15°. In this way, when the on-board screen 6 is in the initial position, the on-board screen 6 is parallel to the X-axis direction of the vehicle, and when the screen bracket 2 deflects the on-board screen 6 toward the driver's side or the front-seat passenger's side, the on-board screen 6 is deflected at a certain angle with respect to the X-axis direction of the vehicle, and this deflection angle is limited to the range of 0° to 15° to ensure a good experience for both the driver and the front-seat passenger.

[0067] In some embodiments, the screen bracket 2 includes a rotation mechanism 22. One end of the rotation mechanism 22 is configured to connect with the on-board screen 6, and the rotation mechanism 22 can rotate the on-board screen 6 around its center. In this way, the rotation mechanism 22 can rotate the on-board screen 6 around the housing 21 of the rotation mechanism 22, allowing the on-board screen 6 to rotate to any angle within a 360° range. In other words, the on-board screen 6 can not only be deflected toward the driver or front seat passenger, but also rotate 360°.

[0068] The rotation mechanism 22 further includes a third drive assembly 221 and a rotating disk 222. One end of the rotating disk 222 is drivingly connected to the third drive assembly 221, and the other end is configured to be connected to the on-board screen 6. The third drive assembly 221 includes a third drive member 221b, which rotates the rotating disk 222 to rotate the on-board screen 6. In this manner, one end of the rotating disk 222 is drivingly connected to the third drive assembly 221, and the other end is fixedly connected to the on-board screen 6. When the third drive assembly 221 rotates the rotating disk 222 around the housing 21 of the rotation mechanism 22, the rotating disk 222 can rotate the on-board screen 6.

[0069] For example, the third drive assembly 221 may include a third drive member 221b and a worm gear and worm 221a. The worm gear and worm 221a can change the direction of the output power of the third drive member 221b so that the output direction of the worm gear and worm 221a is aligned with the axial direction of the rotating disk 222.

[0070] For example, the rotation mechanism 22 may further include a housing 21, a convex ring 223, a gear wheel 224, and a spring retaining ring 225. The convex ring 223 and the gear wheel 224 are sleeved sequentially on the rotating disk 222 and attached to the housing 21 through the spring retaining ring 225. In this way, it can be ensured that the rotating disk 222 rotates relative to the housing 21.

[0071] In some usage situations, if the driver notices a reflection on the screen, by clicking the "left turn" control button on the steering wheel once, the display screen will turn 15° directly towards the driver, or by pressing the "left turn" control button for a long time, the screen can stop at any position within the range of 0° to 15° during the process of turning towards the driver.

[0072] Similarly, in some usage situations, if the front seat passenger needs to see the screen, the driver can click the "right turn" control button on the steering wheel once, and the display screen will turn 15° directly toward the front seat passenger, or by pressing and holding the "right turn" control button, the screen can stop at any position within the range of 0° to 15° during the process of turning toward the front seat passenger side. A separate control button may be mounted at the front seat passenger's position, and control of the sideways turning of the screen can be achieved through the same control logic.

[0073] If it is necessary to return to the initial position, the operator simply clicks the "Center / Rotate" button once and the screen returns to its initial horizontal position from its rotated left or right state.

[0074] If the user needs to navigate or use some applications that require vertical screen operation, they can double-click the "Center / Rotate" button to switch between horizontal and vertical screens. For example, if the driver clicks "Turn Left" and then double-clicks "Center / Rotate," the mechanism will rotate toward the driver while the screen will rotate around its center to switch between horizontal and vertical screens; the two actions are performed in unison.

[0075] An on-board screen assembly 100 according to an embodiment of the second aspect of the present disclosure includes an on-board screen 6 and an adjustment device 50 for the on-board screen, where the on-board screen 6 is fixed on a screen bracket 2. Through the operation of a rotation mechanism 22, a first drive assembly 32, and a second drive assembly 42, integration of lateral pivoting and rotation functions of the on-board screen assembly 100 can be achieved.

[0076] As shown in FIG. 7, a vehicle 1000 according to an embodiment of the third aspect of the present disclosure includes an on-board screen assembly 100 and a mounting base 1, and the on-board screen assembly 100 is fixed on the vehicle 1000 through the mounting base 1.

[0077] Specifically, a plurality of mounting holes are arranged in the mounting base 1. The entire on-board screen assembly 100 can be fixed by being fixedly connected to the vehicle frame body through these mounting holes. Furthermore, the first feed screw and the second feed screw are interference-fitted with the mounting base 1 through bearings.

[0078] Therefore, by moving the first link 31 with the first drive assembly 32 and the second link 41 with the second drive assembly 42, the screen bracket 2 and the on-board screen 6 can be deflected and translated toward the driver's side or toward the front passenger's side, effectively solving the problem of large field of view obstruction when turning toward the driver's side and the problem of small gaps between the screen and the combination switch and steering wheel when turning toward the front passenger's side. Furthermore, 360-degree rotation of the on-board screen 6 can also be achieved through the rotation mechanism 22, allowing arbitrary rotation between a horizontal screen and a vertical screen. The on-board screen assembly 100 integrates both lateral pivoting and rotation functions to improve convenience of use.
