Description

A seat armrest integrated with a table board and a touch screen

technical field

The invention relates to a vehicle accessory, in particular to a seat armrest.

Background technique

With the rapid development of automobile technology and the rapid growth of car ownership, consumers' demand for cars for transportation has gradually developed into the pursuit of functionality, comfort and sense of technology. Especially for SUVs and some commercial MPVs, consumers may need to carry out various activities such as office, dining, leisure and entertainment during the journey.

Therefore, if the seat has an integrated table function and provides a touch screen to control and adjust the seat function and vehicle function, it will be sought after by consumers. At present, there are generally three types of seats that provide table boards:

The tray table integrated into the backrests of the front seats can be folded back for use by the second-row passengers. However, this table board is far away from the passengers in the second row, and the operability and comfort during use are poor. Moreover, since the table board is fixed to the backrest of the front seat when it is folded, the thickness of the seat is increased and the space for the second row is reduced.

Most of the side-turning table boards integrated in the inner armrests of the second row of seats use vertical slide rails, and the table boards need to be pulled vertically upwards and then folded to the inside of the seats for use. This desk board area is little, and practicability is poor, and height is low, and convenience is poor. Many table tops require armrests to be lowered to cover the table tops after they are turned over and opened, so that the height of the top boards must be lower than the height of the handrails, so that the height of the top boards is too low, which is very inconvenient to use.

Based on this, it is desired to provide a seat armrest integrated with a table board and a touch screen to overcome the above-mentioned technical defects.

Fig. 25 schematically shows the setting state of the micro switch in an embodiment of the seat armrest integrated with the table board and the touch screen according to the present invention.

FIG. 26 is a partially enlarged view at point C in FIG. 25 .

As shown in Fig. 25 and Fig. 26, in one embodiment, on the armrest frame 11 of the lower body of the armrest, the microswitch installation groove P is installed by the bolt Q, and the microswitch 7 is located therein. When the folding table assembly 2 rotates around the folding table rotating shaft 21 until the micro switch trigger 222 no longer presses the spring leaf 71 of the micro switch, the micro switch 7 is triggered, and the motor 52 is controlled so that the touch screen 53 retracts. .

The seat armrest integrated with the table board and the touch screen according to the present invention can be operated according to the following steps:

1. Operate the touch screen: press the touch screen control button 58, and the touch screen 53 will automatically extend forward by a set distance, such as 56 mm, under the drive of the motor 52, and raise the set angle relative to the horizontal plane, such as 24 mm. °, as shown in Figure 27. After the screen slides out, the touch area of the screen can be enlarged, and the lifting angle can make the viewing angle of the screen better and more convenient to operate. Press the touch screen control button 58 again, and the screen will automatically shrink back to the horizontal state under the drive of the motor.

Open the armrest: press the unlock button 41 to unlock the upper body of the armrest; the upper body 3 of the armrest will open slowly and automatically at a certain angle, such as 30°, with the help of the damping gear, damping rack and booster spring; when the upper body of the armrest is opened, The pneumatic strut 8 will push the folding table upward for a certain distance, such as 70 mm, so that the folding table rotates around the folding table rotating shaft 21 at a certain angle, such as 15°, so that the handle 251 of the folding table is exposed from the accommodating cavity 12 , to facilitate the removal of the folding table, as shown in Figure 28.

When the folding table rotates at a set angle, such as 15°, the microswitch trigger 222 on the vertical support arm 22 triggers the microswitch 7 from the contact state shown in Figure 29 to the loose state shown in Figure 30. In the open state, the touch screen 53 is controlled to retract, so as to avoid interference between the touch screen and the opened table after the armrest is put down.

Manually continue to open the upper body 3 of the armrest to 90°. At this time, the touch screen 53 is in a fully retracted state, and the table is rotated to a certain angle, such as 15°, to facilitate taking out the table, as shown in FIG. 31 .

3. Open the folding table: Manually rotate the folding table to the vertical position through the handle 251, as shown in Figure 32. Turn over the folding table so that the horizontal support plate 25 is in a horizontal state, as shown in FIG. 33 . Slide the rear panel 27 along the slide rail 28, as shown in Figure 34. In this way, the table board can be adjusted to a proper position. In some specific embodiments, the maximum sliding stroke of the table board is 207 mm. Turn the front panel 26 upwards so that the folding table panel is fully opened, as shown in FIG. 35 . Then, close the upper body of the armrest and use the table board.

In some specific embodiments, the expanded length and width of the table can reach 280 mm × 320 mm, and there is still a minimum distance of 25 mm between the legs of the tall mannequin and the lower part of the table, so the space is sufficient and easy to use.

The combination of the technical features in this case is not limited to the combination described in the claims of this case or the combination described in the specific examples. All the technical features recorded in this case can be freely combined or combined in any way, unless they are mutually incompatible. Conflicts arise between.

It should also be noted that the above-mentioned embodiments are only specific embodiments of the present invention. Apparently, the present invention is not limited to the above embodiments, and the similar changes or deformations made thereupon can be directly obtained or easily thought of by those skilled in the art from the disclosed content of the present invention, and all should belong to the protection scope of the present invention .
