Passengers may need to use laptops or write documents during the ride, and during long-distance driving, passengers also need to use the time to rest.

[0003] Technicians have designed and developed car seats that can be used for working or sleeping in the car. For example, a Chinese patent (patent number ZL02217520.2; authorization announcement CN2541250Y) discloses a composite safety seat, which includes a seat body, a folding table is arranged behind the seat body backrest, the desktop of the folding table is movably connected to the seat body backrest, a telescopic rod supporting the desktop is arranged under the desktop of the folding table, one end of the telescopic rod is movably connected to the desktop, and the other end is arranged at the bottom behind the seat body, and the desktop of the folding table is provided with a foldable extension plate.

[0004] Although the folding table of the above-mentioned composite safety seat can be folded and stored, the height of the folding table and the inclination of the desktop cannot be adjusted according to the needs of the passengers, and cannot meet the requirements of passengers of different body shapes for the position of the folding table when they are working or sleeping. Moreover, when the backrest is adjusted forward or backward, the position of the desktop (including the height, angle and distance from the passenger) will change. If the position of the desktop cannot be adjusted, it will seriously affect the comfort of the passengers. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention aims to provide a hidden table which can be adjusted adaptively and a method for adaptively adjusting the same, wherein the angle, height and distance between the table and the rear passenger are adjustable, and when the backrest is flipped over, the angle, height and distance between the table and the rear passenger can be adaptively adjusted according to the angle of the backrest.

[0006] In order to achieve the above-mentioned purpose, the present invention proposes a hidden table top that can be adaptively adjusted, including a backrest and a table top, wherein the table top is stored behind the backrest and a locking mechanism is arranged between the backrest and the backrest, and the backrest is driven to rotate by a backrest motor, and also includes an internal folding motor arranged inside the backrest, a connecting rod is arranged on the internal folding motor, and the other end of the connecting rod is connected to a telescopic flipping mechanism, a mechanical arm is arranged on the telescopic flipping mechanism, and the other end of the mechanical arm is connected to a table top folding motor, and the table top folding motor is connected to the table top; when the locking mechanism is unlocked, the internal folding motor can drive the connecting rod to flip, the telescopic flipping mechanism can drive the mechanical arm to flip and extend to push out the table top, and the table top folding motor can drive the table top to flatten to realize the opening of the table top.

[0007] In the above scheme: the telescopic flipping mechanism is a telescopic flipping cylinder, or a folding motor and a telescopic motor connected together, which can realize both the telescopic function and the flipping function.

[0008] In the above scheme: it also includes a controller for controlling the backrest motor, internal folding motor, telescopic flip mechanism and table top folding motor, and the Hall signal output end of the backrest motor is connected to the signal collection end of the controller, that is, the controller can collect the Hall signal of the backrest motor.

[0009] The present invention also proposes an adaptive adjustment method for an adaptively adjustable hidden table top. Based on the adaptively adjustable hidden table top, the adaptive adjustment method includes:

[0010] S1, when the backrest is flipping, the controller collects the Hall signal of the backrest motor before and after the backrest is flipped;

[0011] S2. Calculate the deviation angle of the current movement based on the difference between the two Hall signals;

[0012] S3. Calculate the horizontal displacement generated by the current movement according to the offset angle;

[0013] S4. According to the offset angle, the table top folding motor and the internal folding motor are controlled to compensate in the opposite direction. The table top folding motor drives the table top to maintain a flat state, and the internal folding motor drives the table top to maintain its initial height from the ground. At the same time, according to the horizontal displacement, the telescopic flipping mechanism is controlled to drive the mechanical arm to extend or flip to maintain the designed distance between the table top and the rear passengers.

[0014] In the above scheme: during the backrest flipping process, the controller detects the movement state of the backrest in real time, thereby controlling the table top folding motor, internal folding motor and telescopic flipping mechanism to move in real time. When the backrest stops moving, the adaptive adjustment of the table top also ends.

[0015] The beneficial effects of the present invention are:

[0016] The table top can be folded and hidden behind the backrest when not in use, and can be automatically unfolded when in use. The angle, height and distance between the table top and the rear passenger are all adjustable, and the passenger can adjust them as needed. When the backrest is flipped, the angle, height and distance between the table top and the rear passenger can be adaptively adjusted according to the angle of the backrest. In short, the present invention occupies a small space and has a high degree of intelligence. It adopts a fully electronic control design, has a high degree of customization, and is highly safe and controllable. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1 —As shown in FIG4 , a hidden table top with adaptive adjustment is mainly composed of a backrest 1 and a table top 2. The table top 2 is stored at the rear side of the backrest 1 and a locking mechanism is provided between the table top 2 and the backrest 1. The backrest 1 is driven to rotate by a backrest motor.

[0022] An internal folding motor 3 is arranged inside the backrest 1, and a connecting rod 4 is arranged on the internal folding motor 3. The other end of the connecting rod 4 is connected to a telescopic flipping mechanism 5. A mechanical arm 6 is arranged on the telescopic flipping mechanism 5. The other end of the mechanical arm 6 is connected to a table top folding motor 7. The table top folding motor 7 is connected to the table top 2.

[0023] When the locking mechanism is unlocked, the internal folding motor 3 can drive the connecting rod 4 to flip, the telescopic flipping mechanism 5 can drive the mechanical arm 6 to flip and extend to push out the table top 2, and the table top folding motor 7 can drive the table top 2 to flip flat to achieve the opening of the table top 2.

[0024] Preferably, the telescopic flipping mechanism 5 is a telescopic flipping cylinder, or a folding motor and a telescopic motor connected together, which can realize both the telescopic function and the flipping function.

[0025] Preferably, it also includes a controller for controlling the backrest motor, the internal folding motor 3, the telescopic flipping mechanism 5 and the table top folding motor 7, and the Hall signal output end of the backrest motor is connected to the signal collection end of the controller, that is, the controller can collect the Hall signal of the backrest motor.

[0026] An adaptive adjustment method for an adaptively adjustable hidden table top, based on the above-mentioned adaptively adjustable hidden table top, the adaptive adjustment method includes:

[0027] S1. When the backrest is flipping, the controller collects the Hall signal of the backrest motor before and after the backrest 1 is flipped.

[0028] S2. Calculate the deviation angle of the current movement based on the difference between the two Hall signals.

[0029] S3. Calculate the horizontal displacement caused by the current movement according to the offset angle.

[0030] S4. According to the offset angle, the table top folding motor 7 and the internal folding motor 3 are controlled to compensate in the opposite direction. The table top folding motor 7 drives the table top 2 to maintain a flat state, and the internal folding motor 3 drives the table top 2 to maintain its initial height from the ground. At the same time, according to the horizontal displacement, the telescopic flipping mechanism 5 is controlled to drive the mechanical arm 6 to telescope or flip to maintain the designed distance between the table top 2 and the rear passenger.

[0031] Preferably, during the flipping process of the backrest 1, the controller detects the movement state of the backrest 1 in real time (the controller detects based on the Hall signal of the backrest motor), thereby controlling the real-time movement of the table top folding motor 7, the internal folding motor 3 and the telescopic flipping mechanism 5. When the backrest 1 stops moving, the adaptive adjustment of the table top 2 also ends. The table top 2 is adjusted in real time with a high degree of automation.
