Description

Technical Field

[0001] The invention belongs to the technical field of automobile interior trim manufacturing, and in particular relates to a passenger entertainment system driven by an electric simple rotary arm and having an integrated small table. Background Art

[0002] Existing high-end cars have an armrest box between the two rear seats. With the continuous development of manufacturing technology and the continuous improvement of production processes, the armrest box has added a storage function, such as storing small items such as drinks and water cups, so that the driver can easily access these small items when needed. In addition, to meet the needs of people's fast-paced lifestyles, existing cars usually install table boards in the armrest box for passengers to work or eat. For example, CN 215501723 U discloses a "hidden folding table for automobiles." This patent installs the folding table movably in the hollow armrest box cover, but the folding table needs to be manually adjusted, and the angle and range of adjustment of the folding table are limited. CN 108621967 A discloses a "car auxiliary instrument panel with a table top and a slide rail system". This patent installs an armrest box on the auxiliary instrument panel, and inside the armrest box are installed a table top rotation support mechanism, a table top horizontal rotation mechanism connected to the table top rotation support mechanism, and a table top body installed on the table top horizontal rotation mechanism. The table top body of this patent also has the problem of requiring manual adjustment, and the adjustment angle and range of the table top body are limited.

If monitors could be installed in the rear seats of cars, it would greatly enhance the passengers' enjoyment. However, existing cars lack space for monitors in the rear seats. Therefore, it is particularly important to develop a passenger entertainment system that can integrate work, dining, and entertainment. Summary of the Invention

[0064] In addition, the electric simple rotary arm 1 described in the present invention is composed of four independent mechanisms, and there will be a small gap between each independent mechanism.

[0065] Example 2

[0066] See Figures 4 to 6 The present invention provides a simple electric swing arm, comprising a rotating mechanism 11, a telescopic mechanism 12, a tilting mechanism 13, and a flipping mechanism 14. The rotating mechanism 11 is configured to bear the entire weight and is fixedly connected to the telescopic mechanism 12 for adjusting the angle of the telescopic mechanism 12. The telescopic mechanism 12 is fixedly connected to the tilting mechanism 13, which in turn is fixedly connected to the flipping mechanism 14. The telescopic mechanism 12 is used to adjust the length, while the tilting mechanism 13 is used to adjust the tilting angle between the telescopic mechanism 12 and the tilting mechanism 13. The flipping mechanism 14 is equipped with an adjustable part, which is flipped along the X-axis and rotated along the Y-axis by the flipping mechanism 14. This swing arm structure has a 3D motion mode, enabling multi-angle and wide-range adjustment.

[0067] In addition, in order to ensure that the electric simple rotary arm is compactly installed and occupies a small space, the rotating mechanism 11, the telescopic mechanism 12, the tilting mechanism 13, and the rotating mechanism 14 of the electric simple rotary arm are designed respectively, such as Figures 7 to 11As shown, the specific structure is the same as that of Example 1.

[0068] Example 3

[0069] The present invention provides a control method for a passenger entertainment system with an integrated small table driven by an electric simple rotary arm, the method comprising the following steps:

[0070] Step S1: Open the electric door of the armrest box. You can choose to open it manually or press the operation button to open the electric door through the controller;

[0071] Step S2: After the controller senses that the electric door is open, it drives the tilt mechanism to operate, and the tilt mechanism, the rotating mechanism, and the small table in the armrest box receiving slot tilt toward the outside of the armrest box until the end of the tilt mechanism is completely offset from the upper edge of the armrest box;

[0072] Step S3: The controller drives the expansion motor to rotate, causing the expansion motor to rotate the telescopic mechanism in a clockwise direction. At this time, the tilt mechanism, the rotation mechanism, and the small table are moved away from the receiving slot of the armrest box, and the electric door of the armrest box is closed.

[0073] Step S4: The passenger controls the rotation mechanism according to actual needs. When the tray table needs to be used, the rotation mechanism controls the tray table to be flipped along the X-axis so that the front of the tray table faces upward. When the display needs to be used, the rotation mechanism controls the tray table to be flipped along the X-axis so that the display on the back of the tray table faces the passenger. When there is interference on the tray table in the vehicle, the rotation mechanism controls the tray table to be rotated along the Y-axis so that the tray table is in an upright position.

[0074] Step S5: After selecting to use the tray table or display, the passenger can adjust the length of the telescopic mechanism and the tilt angle of the tilt mechanism according to actual needs to place the tray table or display in a relatively appropriate position, thereby completing the tray table or display adjustment;

[0075] Step S6: When the small table needs to be folded up, the electric door of the armrest box is opened again, and the rotation mechanism is controlled to adjust the small table to a state parallel to the armrest box;

[0076] Step S7: Control the telescopic mechanism to reset, and then control the tilt mechanism so that the tilt mechanism, the rotating mechanism, and the small table are directly above the space between the armrest box and the electric door;

[0077] Step S8: The controller drives the expansion motor to rotate, causing the expansion motor to rotate counterclockwise. At this point, the tilt mechanism, the rotation mechanism, and the small table are close to the receiving slot of the armrest box.

[0078] Step S9: Continue to drive the tilt mechanism so that the tilt mechanism, the rotating mechanism and the small table are placed in the receiving slot of the armrest box, thereby completing the folding of the small table, and finally closing the electric door of the armrest box.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention, rather than to limit them. Although the embodiments of the present invention have been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the embodiments of the present invention.
