The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0034] Please refer to Figure 1 and Figure 2 The purpose of the present invention is to provide a seat table automatic folding component 100, which is applied to a seat 200 in a car, a high-speed train or an airplane. The table automatic folding component 100 is installed on the rear side of a backrest 201 of the seat 200. By using the seat table automatic folding component 100, the seat 200 can realize automatic folding and automatic opening of the table 202 relative to the backrest 202, thereby realizing intelligent automatic control.

[0035] Please refer to Figures 3 to 7 The seat table automatic folding assembly 100 comprises:

[0036] A seat bracket 10, used for mounting and connecting the rear side of the seat back 201;

[0037] The table frame 20 is used to install and form a table 202;

[0038] An active connecting rod 30, both ends of which are rotatably connected to the seat support 10 and the table frame 20;

[0039] The driven connecting rod 40 has two ends which are rotatably connected to the seat support 10 and the table frame 20; and

[0040] A driving mechanism 50 is provided on one of the seat bracket 10 or the table frame 20, and the driving mechanism 50 is transmission-connected to the end of the active connecting rod 30 connected to the corresponding seat bracket 10 or the table frame 20;

[0041] Among them, the driving mechanism 50 can drive the active connecting rod 30 to rotate relative to the corresponding one of the seat bracket 10 or the table board frame 20, drive the active connecting rod 30 to rotate relative to the other of the seat bracket 10 or the table board frame 20, and the driven connecting rod 40 to rotate relative to the seat bracket 10 and the table board frame 20 respectively, so as to realize the rotational folding or rotational opening of the table board frame 20 relative to the seat bracket 10.

[0042] In this embodiment, the driving mechanism 50 drives the active connecting rod 30 to rotate, thereby driving the driven connecting rod 40, the seat frame 10, and the table frame 20 to rotate and move within a restricted trajectory, thereby realizing the relative folding or opening of the table frame 20 relative to the seat frame 10. The structure is simple and intelligent automatic control is used, avoiding manual operation or a complex control structure.

[0043] Specifically, the seat support 10 can be detachably mounted and connected to the seat back 202 to achieve structural modularization. It can be understood that in other embodiments, the seat support 10 can also be a part of the seat back 202.

[0044] Among them, at least one of the rotational connections between the active link 30 and the driven link 40 and the seat bracket 10 or the table frame 20 is a hinged structure, and a stable output of the drive is achieved through the hinge. All hinges use bearings, including but not limited to angular contact ball bearings and deep groove ball bearings, to achieve the effect of noise reduction and extended service life. In addition, a damping gasket can also be set inside the hinge structure.

[0045] Furthermore, the number of the active connecting rods 30 is set to two, which are respectively arranged at the two ends of the seat bracket 10 and the table board frame 20. The driving mechanism 50 includes a linkage shaft 51 and a driving motor 52 connected to the linkage shaft 51. The two ends of the linkage shaft 51 are respectively connected to the two active connecting rods 30.

[0046] The driving motor 52 is a self-locking motor. When the table frame 20 is opened, the self-locking property of the motor is utilized so that the table frame 20 can bear the heavy objects on the table 202 without rotating and folding in the opposite direction.

[0047] In this embodiment, by setting a pair of active connecting rods 30, the stability of the rotational connection between the table frame 20 and the seat frame 10 is further improved, and the linkage shaft 51 is set to connect the two active connecting rods 30 respectively, which increases the output stability of the driving mechanism 50. It can be understood that in other embodiments, a single active connecting rod 30 can also drive the table frame 10 and the seat frame 20 to rotate, and its setting position can be in the relative middle. In addition, even if a pair of active connecting rods 30 are set, the linkage shaft 51 can also be omitted. By driving one of the active connecting rods 30 through the driving motor 52, the other active connecting rod 30 will also rotate synchronously. Specifically, the linkage shaft 51 includes a first drive shaft 511 connected to the motor, a drive shaft 512 connected to the active connecting rod 30, and a coupling 513 connecting the first drive shaft 511 and the second drive shaft 512.

[0048] Furthermore, the driving mechanism 50 also includes an electronic control unit (ECU) connected to the driving motor, and the ECU is used to control the movement of the driving motor 52 .

[0049] Furthermore, the ECU can also receive external power supply, receive external control signals, or send status signals to the outside. In this embodiment, the ECU serves as a control center, receives external control signals and power supply to control the movement of the drive motor 52, and realizes the intelligence expansion to the outside, such as receiving the control signal of the car. It can be understood that in other embodiments, the ECU can also have its own power supply module, and the external signal received can be a control signal of an external button or a voice control signal of an external user, etc., so as to meet various intelligent needs.

[0050] Furthermore, the driving mechanism 50 also includes an angle sensor (not shown) or a gyroscope (not shown), and the angle sensor or the gyroscope is used to monitor the rotation angle of the table frame 20 and feed back to the ECU, and the ECU controls the movement of the driving motor 52 according to the rotation angle to control the table frame 20 to maintain a horizontal position in the open state. In this embodiment, the state of the table frame 20 is monitored in real time by the angle sensor or the gyroscope, so that the table 202 can always be kept in a horizontal state under different seat angles. It is understandable that when the table frame 20 is in a folded state, the angle sensor or the gyroscope does not intervene in the work, and intervenes in the work only after receiving the opening command and control.

[0051] Furthermore, the driving mechanism 50 is disposed on the table frame 20, and the active connecting rod 30 is provided with a wiring groove 31 and a wire groove cover 32 adapted to the wiring groove 31, and the wiring groove 31 and the wire groove cover 32 are used to accommodate the connection cables disposed between the ECU and the outside. In this embodiment, by providing the wiring groove 31 and the wire groove cover 32, the ECU power supply cable or communication cable is hidden, and the wiring structure is optimized.

[0052] Furthermore, the number of the driven connecting rods 40 is set to two, which are respectively set corresponding to the two active connecting rods 30; the driving mechanism 50 is set on the lower side of the table frame 20 and the front side adjacent to the seat frame 10, the first end of the active connecting rod 30 is connected to the driving mechanism 50, the second end of the active connecting rod 30 is connected to the lower side of the seat frame 10, and the two ends of the driven connecting rod 40 are respectively connected to the middle part of the table frame 20 and the upper side of the seat frame 10. Through the above structural setting, the layout structure of the active connecting rod 30, the driven connecting rod 40 and the driving mechanism 50 is optimized, the space occupied by the rotating structure is reduced, and the use state of the table frame 20 is not affected.

[0053] Furthermore, the active link 30 includes a first rod portion 33 and a second rod portion 34 bent and connected to the first rod portion 33, the length of the first rod portion 33 is greater than the length of the second rod portion 34, the bending angle between the first rod portion 33 and the second rod portion 34 is an obtuse angle, and the direction of the bending angle corresponds to the direction of the angle between the seat support 10 and the table frame 20. In this embodiment, the active link 30 is set to a quasi-L-shaped structure, and the bending angle direction thereof is adapted to the angle direction between the table frame 20 and the seat support 10 in the open state, that is, in the open state, the main part of the active link 30 can be relatively closer to the seat back 202, further reducing the space occupied by the folding structure.

[0054] Further, the driven connecting rod 40 includes a third rod portion 41, a bent portion 42 and a fourth rod portion 43 connected in sequence, the direction of the third rod portion 41 corresponds to the direction of the fourth rod portion 43, the bent portion 42 is bent relatively away from the active connecting rod 30, and the bent portion 42 corresponds to the end of the active connecting rod 30 connected to the driving mechanism 50. In this embodiment, the setting of the bent portion 42 is to make way for the connection structure between the active connecting rod 30 and the driving mechanism 50, without the need to offset the driven connecting rod 40 as a whole, thereby reducing the space occupied by the folding structure.

[0055] Furthermore, the active connecting rod 30 or the driven connecting rod 40 is respectively rotatably connected to the connecting block 11 (21) fixed to the seat bracket 10 or the table board frame 20, so that the active connecting rod 30 or the driven connecting rod 40 is respectively rotatably connected to the seat bracket 10 and the table board frame 20.

[0056] Please refer to Figure 5 and Figure 6 ,like Figure 5 As shown, the table frame 20 is in the open state. When the drive motor 52 receives the "fold" signal from the ECU, the drive motor 52 drives the active link 30 to rotate clockwise, and the entire active link 30 and the driven link 40 move according to the designed position and trajectory, driving the table frame to rotate and fold until it is completely folded. Figure 6 shown.

[0057] In the second aspect, an embodiment of the present invention further provides a seat 200 with a foldable table, including the seat table automatic folding assembly 100 according to the above-mentioned seat frame 10 installed and connected to the rear side of the seat back 201, and the table frame 20 installed to form a table 202.
