[0055] In a second aspect, an embodiment of the present application provides a vehicle, which includes a vehicle-mounted ceiling screen device as described in some of the above embodiments.

[0056] In a third aspect, an embodiment of the present application provides a method for adjusting a vehicle-mounted ceiling screen device, which includes the vehicle-mounted ceiling screen device as described in some of the above embodiments, and further includes the following steps:

[0057] S100: In response to the user's demand for using the display screen, control the driving component to drive the foldable display screen 3 to flip within the set angle range, and control the translation component 1 to drive the foldable display screen 3 to move to a distance within the set distance range from the rear passenger's eyes, and control the foldable display screen 3 to unfold within the set angle range, so that the rear passengers are at a comfortable viewing distance and angle.

[0058] In this embodiment, in response to the user's demand for using the display screen, the driving component can be controlled to drive the foldable display screen 3 to flip out of the accommodating slot 21, and the angle α1 at which the foldable display screen 3 is flipped out of the accommodating slot 21 can be controlled to perform the first angle adjustment so that its angle is a comfortable viewing angle, and the translation component 1 can be controlled to control the foldable display screen 3 on the movable plate 2 to move along the length direction of the vehicle body, and the distance L2 between the foldable display screen 3 and the eyes of the rear passengers can be controlled to be a comfortable viewing distance, and the foldable display screen 3 can be controlled to unfold at an angle α2, and the viewing angle can be adjusted for the second time. At the same time, through the structure of the foldable display screen 3 and the foldable display screen 3 can be stored in the accommodating slot 21 when not in use, its layout space is smaller than that of a traditional ceiling screen, which reduces the occupied space, can greatly expand the field of vision transparency of the cabin, and bring a better cabin experience.

[0059] Among them, Figure 3 As shown, the angle α1 range of the foldable display screen 3 flipped out of the receiving groove 21, the distance L2 between the foldable display screen 3 and the rear passengers, and the unfolding angle α2 of the foldable display screen 3, engineers can collect a large amount of data during the design and testing phase to meet the viewing experience of most users. After the vehicle-mounted ceiling screen device adaptively adjusts the setting range of the viewing distance L2, the flipping viewing angle α1 of the foldable display screen 3, and the unfolding angle α2 of the foldable display screen 3, users can also make differentiated adjustments according to their own needs, such as voice control of its distance and viewing angle or manual button control of the distance and viewing angle.

[0060] In conjunction with the third aspect, in one implementation, in S100, the following steps are included:

[0061] S101: If the user's usage requirement is mild, the driving component is controlled to drive the foldable display screen 3 in the folded state to flip to a set angle range, so that the rear passengers are at a comfortable viewing angle;

[0062] S102: Control the translation assembly 1 to drive the foldable display screen 3 to move to a distance within a set range from the eyes of the rear passengers, so that the rear passengers are at a comfortable viewing distance.

[0063] In this embodiment, if the user's usage needs are mild (such as displaying weather, calendar, meeting minutes, brief news, stocks, schedule and / or lyrics), the foldable display screen 3 does not need to perform the unfolding action (that is, the unfolding angle of the foldable display screen 3 itself is 0), and its external display screen 324 displays the above information, that is, the driving component is used to drive the folded foldable display screen 3 to flip out of the set angle range outside the accommodating groove 21, so that the rear passengers are at a comfortable viewing angle, and the translation component 1 is controlled to control the foldable display screen 3 to move along the length direction of the vehicle body to within the set distance range, so that the rear passengers are at a comfortable viewing distance.

[0064] In conjunction with the third aspect, in one implementation, in S100, the following steps are included:

[0065] S101: If the user's usage requirement is heavy, the driving component is controlled to drive the foldable display screen 3 in the folded state to flip to within a set angle range, and the foldable display screen 3 in the folded state is controlled to unfold to within the set angle range, so that the rear passengers are at a comfortable viewing angle;

[0066] S103: Control the translation assembly 1 to drive the foldable display screen 3 to move to a distance within a set range from the eyes of the rear passengers, so that the rear passengers are at a comfortable viewing distance.

[0067] In this embodiment, if the user's usage needs are heavy (such as watching movies, live broadcasts or games), the foldable display screen 3 needs to perform an unfolding action, and its inner display screen 1 311 and inner display screen 2 321 display the above information, that is, the driving component is used to drive the folded foldable display screen 3 to flip out of the accommodating slot 21 to within a set angle range, and control the folded foldable display screen 3 to unfold within the set angle range, so that the rear passengers are at a comfortable viewing angle, and control the translation component 1 to control the foldable display screen 3 to move along the length direction of the vehicle body to within a set distance, so that the rear passengers are at a comfortable viewing distance.

[0068] In conjunction with the third aspect, in one implementation, before S103, the following steps are included:

[0069] S102-1: Obtain the tilt angle of the front seat, the adjustment coordinate points of the front seat along the length direction of the vehicle body, and the torso height of the front occupant, and calculate the coordinates of the back of the front occupant's head in the vehicle coordinate system;

[0070] S102-2: Calculating the distance between the bottom of the foldable display screen 3 and the back of the front row occupant's head based on the coordinates of the back of the front row occupant's head in the vehicle coordinate system and the coordinates of the bottom of the foldable display screen 3 unfolded within a set angle range;

[0071] S102-3: If the distance between the bottom of the foldable display screen 3 and the back of the front row occupant's head is less than a set threshold, the translation component 1 is controlled to drive the foldable display screen 3 to move along the rear of the vehicle body until the distance between the foldable display screen 3 and the back of the front row occupant's head is greater than or equal to the set threshold.

[0072] In this embodiment, the user's usage demand is heavy (such as watching movies, live broadcasts or games), and the foldable display screen 3 needs to perform an unfolding action. When the foldable display screen 3 needs to perform the unfolding condition, there will be interference between the foldable display screen 3 and the back of the head of the front-row personnel (front-row passengers or drivers) along the length direction of the vehicle body, which will affect the riding experience of the front-row passengers or the driver's safe driving. Therefore, before using the translation component 1 to control the foldable display screen 3 on the movable plate 2 to move a set distance along the length direction of the vehicle body so that the rear-row passengers are at a comfortable viewing distance, the distance between the bottom end of the foldable display screen 3 and the back of the head of the front-row personnel along the length direction of the vehicle body needs to be set to be greater than or equal to the set threshold value d, so as to ensure the riding experience of the front-row passengers or the driver's safe driving.

[0073] Among them, Figure 3 As shown, according to L1=Htanα3, after calculating the length of L1, the distance of L1 is added to the X-axis direction of the coordinate point B, and the coordinate of the back of the head of the front occupant on the X-axis can be obtained, and based on the coordinate of the bottom end of the foldable display screen 3 on the X-axis, the distance between the two along the length direction of the vehicle body can be calculated.

[0074] Among them, Figure 3 As shown, the data of the front seat tilt angle α3 and the coordinate point B of the front seat adjusted along the length direction of the vehicle body can be directly obtained in the vehicle system, and the torso height data of the front row occupant can be input by the average torso height H of people in the area or the front row occupant can input the torso height H of his or her upper body, or the torso height H of the front row occupant can be obtained and calculated by taking a photo with the rear camera 322.

[0075] Among them, in the vehicle coordinate system, the X-axis direction is the vehicle length direction, the Y-axis direction is the vehicle width direction, and the Z-axis direction is the vehicle height direction. Figure 3 The side view of the vehicle body shown is the XZ axis coordinate system.

[0076] In conjunction with the third aspect, in one implementation, before S103, the following steps are included:

[0077] S102-1: Obtain a three-dimensional image of the interior of the cab captured by the rear camera 322 of the foldable display screen 3, and calculate the coordinates of the back of the front row occupant's head in the vehicle coordinate system based on the three-dimensional image;

[0078] S102-2: Calculating the distance between the bottom of the foldable display screen 3 and the back of the front row occupant's head based on the coordinates of the back of the front row occupant's head in the vehicle coordinate system and the coordinates of the bottom of the foldable display screen 3 unfolded within a set angle range;

[0079] S102-3: If the distance between the bottom of the foldable display screen 3 and the back of the front row occupant's head is less than a set threshold, the translation component 1 is controlled to drive the foldable display screen 3 to move along the rear of the vehicle body until the distance between the foldable display screen 3 and the back of the front row occupant's head is greater than or equal to the set threshold.

[0080] In this embodiment, the rear camera 322 of the foldable display screen 3 can be used to capture a three-dimensional image of the cab.
