[0009] Advantages and beneficial effects of the present invention

[0010] 1. The present invention can drive the one-way clutch to rotate through a rotating motor, and the rotation of the one-way clutch drives the rotating shaft meshing with it to rotate, thereby driving the table assembly to open or close through the connecting bracket, and the lifting motor drives the lifting screw to rotate, and the rotation of the lifting screw drives the nut to move up and down, thereby driving the flip motion platform and the small table connected to the flip motion platform to rise or fall. The present application can perform intelligent adjustment of the small table in four directions through the control system of the car, overcoming the problem that the small table can only be adjusted manually in two directions in the existing market.

[0011] 2. The present invention provides a one-way clutch and a gear set meshing with the one-way clutch in the gear boxes on both sides of the table top rotating lifting platform. When power is off or in an emergency, the small table top can be manually closed by the cooperation of the one-way clutch and the gear set.

[0012] 3. The present invention changes the original overlapping arrangement of the PCB board and the magnetic induction coil in the wireless charging module into a parallel arrangement, thereby increasing the wireless charging function of the mobile phone while reducing the thickness of the small table, making the thickness of the small table thinner from the original 30 cm to about 26 cm.

[0013] 4. The present invention superimposes an NFC board above the magnetic induction coil. The NFC board is connected to the ECU of the seat through a wire. The adjustment status information of the small table can be set according to the needs of the passengers through the mobile phone APP. When the small table needs to be adjusted, the mobile phone only needs to be attached to the NFC board. The NFC board reads the information set in the mobile phone APP and transmits it to the ECU. The small table is adjusted through the ECU to achieve the angle and position required by the passenger. BRIEF DESCRIPTION OF THE DRAWINGS
