Therefore, if the chair has the integrated table function and provides the touch screen to control and adjust the functions of the chair and the whole vehicle, the chair is pursued by consumers. There are generally three types of seats that currently provide a table:
and the small table plate is integrated on the backrest of the front row of seats and is folded and unfolded backwards for the second row of passengers to use. However, such a table is far from the second row of passengers, and is less comfortable to operate when used. And, because the table is fixed at the front row seat backrest when being folded, the seat thickness is increased, and the second row space is reduced.
The side-turning table plate integrated in the armrest on the inner side of the second row of seats is mainly provided with a vertical sliding rail, and the table plate needs to be vertically pulled upwards and then turned over and unfolded towards the inner side of the seats for use. The table plate has small area, poor practicability, low height and poor convenience. Many tables need the handrail to put down to cover the table after turning on one's side and opening, lead to the height of table must be less than the handrail height to make the table height too low, it is very inconvenient to use.
In view of the above, it would be desirable to provide a chair armrest integrated with a table and a touch screen to overcome the above technical drawbacks.

Fig. 21 shows a state where the table is not slid out.
Fig. 22 shows the table in a state of sliding out.
As shown in fig. 18-22, in one embodiment, the folding table assembly 2 comprises: the folding table board rotating shaft 21 is fixedly arranged in the accommodating cavity, and the axial direction of the folding table board rotating shaft 21 is consistent with the thickness direction of the lower body of the handrail; the vertical support arm 22 is connected with the folding table rotating shaft 21 and can rotate around the folding table rotating shaft, the microswitch triggering part 222 is arranged on the vertical support arm 22, a pin shaft 221 is further arranged on the vertical support arm 22, and the axial direction of the pin shaft 221 is consistent with the length direction of the armrest lower body 1 (namely the length direction of a vehicle); the oblique supporting arm 23 is hinged with the vertical supporting arm 22 through a pin shaft 221; one end of the connecting block 24 is hinged with the oblique supporting arm 23, and the other end is hinged with the horizontal supporting plate 25; the rear plate 27 is slidably connected to the horizontal support plate 25 by slide rails 28 provided on the horizontal support plate 25; the front plate 26 is hinged to the rear plate 27 by a hinge 211 so that the front plate 26 and the rear plate 27 can be opened relative to each other in the length direction of the armrest lower body; a horizontal stopper 29 is also provided on the horizontal support plate 25 to limit the sliding stroke of the rear plate 27 in the horizontal direction.
Preferably, a handle 251 is provided on the horizontal support plate 25 to facilitate pulling out the folding table.
In this embodiment, the table panel is divided into a front panel and a rear panel, which can be folded to save space. In addition, the folding table assembly 2 may further include another damping gear 212 disposed on the horizontal support plate to prevent the rear plate from sliding freely in the horizontal direction.
In addition, the table folding assembly may further include front and rear stoppers 210 mounted on the vertical support arms 22 to abut against the armrest upper body after the table is unfolded to prevent the table from rotating.
In one embodiment of the present invention, as shown in fig. 24, the armrest framework 11 of the armrest lower body 1 is further provided with a pneumatic brace 8 for applying a force to push the folding table assembly out of the accommodating cavity 12.
Fig. 25 schematically shows the setting state of the microswitch of the chair armrest integrated with the table plate and the touch screen in one embodiment of the invention.
Fig. 26 is a partial enlarged view at C in fig. 25.
As shown in fig. 25 and 26, in one embodiment, a micro switch mounting groove P is mounted on the handle frame 11 of the handle lower body by a bolt Q, and the micro switch 7 is provided therein. When the folding table component 2 rotates around the folding table rotating shaft 21 until the microswitch triggering piece 222 no longer presses the spring piece 71 of the microswitch, the microswitch 7 is triggered, and the motor 52 is controlled to retract the touch screen 53.
The chair armrest integrated with the table plate and the touch screen can be operated according to the following steps:
1. operating the touch screen: by pressing the touchscreen control button 58, the touchscreen 53 is automatically advanced a set distance, e.g., 56mm, and raised a set angle, e.g., 24, relative to the horizontal, as shown in fig. 27, under the drive of the motor 52. The touch area of the screen can be enlarged after the screen slides out, the visual angle of the screen can be better due to the lifting angle, and the operation is more convenient. The touch screen control button 58 is pressed again and the screen will automatically retract to the horizontal position under the drive of the motor.
2. Opening the armrest: the unlocking key 41 is pressed down, and the upper body of the handrail is unlocked; the upper body 3 of the handrail is slowly and automatically opened for a certain angle, such as 30 degrees, under the action of the damping gear, the damping rack and the power spring; when the body is opened on the handrail, the pneumatic support rod 8 can push the folding table plate out upwards for a certain distance, for example, 70mm, so that the folding table plate rotates for a certain angle, for example, 15 degrees around the rotating shaft 21 of the folding table plate, the handle 251 of the folding table plate is exposed out of the accommodating cavity 12, and the folding table plate is convenient to take out, as shown in fig. 28.
When the folding table is rotated by a set angle, for example, 15 °, the microswitch actuation member 222 on the vertical support arm 22 actuates the microswitch 7 to change from the contact state shown in fig. 29 to the release state shown in fig. 30, and the touch screen 53 is controlled to retract so as to avoid the touch screen interfering with the opened table after the handrail is put down.
The body 3 on the armrest is manually opened to 90 °, and at this time, the touch screen 53 is in a fully retracted state, and the table is rotated by a certain angle, for example, 15 °, so that the table is convenient to take out, as shown in fig. 31.
3. Opening the folding table board: the folding table is manually rotated to the upright position by the handle 251 as shown in fig. 32. The folding table is turned over so that the horizontal support plate 25 is in a horizontal state, as shown in fig. 33. The rear plate 27 is slid along the slide rails 28 as shown in fig. 34. This allows the table to be adjusted to a desired position, and in some embodiments the maximum sliding travel of the table is 207mm. The front panel 26 is flipped up so that the folding table is fully open as shown in fig. 35. Then, the upper body of the armrest is closed, and the table is used.
