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

In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will appreciate 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 utility model is to provide an automatic folding assembly 100 for a seat table, which is applied to a seat 200 in a car, high-speed train or airplane. The automatic folding assembly 100 for the seat table is installed on the rear side of a backrest 201 of the seat 200. By utilizing the automatic folding assembly 100 for the seat table, 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 includes:

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

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

[0038] The active connecting rod 30 has two ends that are rotatably connected to the seat bracket 10 and the table frame 20;

[0039] The driven link 40 has two ends that are rotatably connected to the seat frame 10 and the table frame 20; and

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

[0041] In which, 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 table board frame 20 to rotate folding or opening 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 the intelligent automatic control is adopted, avoiding manual operation or a complex control structure.

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

[0044] At least one of the rotational connections between the active link 30 and the driven link 40 and the seat frame 10 or the table frame 20 is a hinged structure, achieving stable drive output. All hinges utilize bearings, including but not limited to angular contact ball bearings and deep groove ball bearings, to reduce noise and extend service life. Damping washers can also be incorporated into the hinged 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 providing a pair of active links 30, the stability of the rotational connection between the table frame 20 and the seat frame 10 is further improved. A linkage shaft 51 is provided to connect the two active links 30, respectively, thereby increasing the output stability of the drive mechanism 50. It is understood that in other embodiments, a single active link 30 can also drive the table frame 10 and the seat frame 20 to rotate, and it can be positioned in the relative middle. Furthermore, even if a pair of active links 30 is provided, the linkage shaft 51 can be omitted. By driving one of the active links 30 through the drive motor 52, the other active link 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 link 30, and a coupling 513 connecting the first drive shaft 511 and the second drive shaft 512.

[0048] Furthermore, the driving mechanism 50 further 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, receive external control signals, or transmit status signals externally. In this embodiment, the ECU serves as the control center, receiving external control signals and power to control the movement of the drive motor 52, thereby achieving externally extended intelligence, such as receiving vehicle control signals. It is understood that in other embodiments, the ECU may also have its own power supply module, and the external signals received may be control signals from external buttons or voice control signals from external users, thereby meeting diverse intelligent needs.

[0050] Furthermore, the drive mechanism 50 also includes an angle sensor (not shown) or a gyroscope (not shown). The angle sensor or the gyroscope is used to monitor the rotation angle of the table frame 20 and provide feedback to the ECU. The ECU controls the movement of the drive 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 horizontal under different seat angles. It is understandable that when the table frame 20 is in the folded state, the angle sensor or the gyroscope does not intervene in the work, and only intervenes after receiving the opening command and control.

[0051] Furthermore, the drive mechanism 50 is mounted on the table frame 20, and the active link 30 is provided with a wiring trough 31 and a trough cover 32 adapted to accommodate the wiring trough 31. The trough 31 and trough cover 32 are used to accommodate cables connecting the ECU to the outside world. In this embodiment, the provision of the wiring trough 31 and trough cover 32 conceals the ECU power cables or communication cables, optimizing the wiring structure.

[0052] Furthermore, there are two driven links 40, one corresponding to each of the two active links 30. The drive mechanism 50 is located on the underside of the table frame 20 and adjacent to the front of the seat frame 10. The first end of the active link 30 is connected to the drive mechanism 50, the second end of the active link 30 is connected to the underside of the seat frame 10, and the two ends of the driven link 40 are connected to the middle of the table frame 20 and the upper side of the seat frame 10, respectively. This structural arrangement optimizes the layout of the active link 30, the driven link 40, and the drive mechanism 50, reduces the space occupied by the rotating structure, and does not affect the usability of the table frame 20.

[0053] Furthermore, the active link 30 includes a first link portion 33 and a second link portion 34 that is bent and connected to the first link portion 33. The length of the first link portion 33 is greater than that of the second link portion 34. The first link portion 33 and the second link portion 34 are bent at an obtuse angle, the direction of which corresponds to the angle between the seat frame 10 and the table frame 20. In this embodiment, the active link 30 is configured as an L-shaped structure, with the angle of its bend matching the angle between the table frame 20 and the seat frame 10 in the unfolded state. Specifically, in the unfolded state, the main portion of the active link 30 can be relatively close to the seat backrest 202, further reducing the space occupied by the folding structure.

[0054] Furthermore, the driven link 40 includes a third rod portion 41, a curved portion 42, and a fourth rod portion 43, which are connected in sequence. The direction of the third rod portion 41 corresponds to the direction of the fourth rod portion 43. The curved portion 42 is bent relatively away from the active link 30 and corresponds to the end of the active link 30 connected to the drive mechanism 50. In this embodiment, the curved portion 42 is provided to make way for the connection structure between the active link 30 and the drive mechanism 50, eliminating the need to offset the entire driven link 40, thereby reducing the space occupied by the folding structure.

[0055] Furthermore, the active link 30 or the driven link 40 is respectively rotatably connected to the connecting block 11 (21) fixed to the seat frame 10 or the table frame 20, so as to realize that the active link 30 or the driven link 40 is respectively rotatably connected to the seat frame 10 and the table 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. The entire active link 30 and the driven link 40 then 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, the embodiment of the present invention also provides a seat 200 with a folding table, including the seat table automatic folding assembly 100 according to the above-mentioned method, the seat bracket 10 is installed and connected to the rear side of the seat back 201, and the table frame 20 is installed to form a table 202.

[0058] In the third aspect, an embodiment of the utility model also provides a car, including a power supply platform, a central control platform, seats and an automatic folding assembly of a seat table according to the first aspect, the driving mechanism is respectively connected to the power supply platform and the central control platform, the seat bracket is installed and connected to the rear side of the seat back, and the table frame is installed to form a table.

[0059] The automatic folding assembly of the seat table, the seat and the car provided by the present invention are equipped with a connecting rod to connect the seat frame and the table frame. The driving mechanism drives the active connecting rod to rotate and drives the driven connecting rod to rotate, so that the table frame can be rotated and folded or rotated and opened relative to the seat frame through the connection between the active connecting rod and the driven connecting rod. The automatic folding assembly of the seat table has a simple structure and can stably control the rotation of the table frame, thereby realizing the intelligence of the seat and the intelligence of the car, and providing users with a good user experience.
