[0028] The embodiments of the present invention are described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, but should not be construed as a limitation of the present invention.

[0029] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or letters in different examples.

[0030] The purpose of the present utility model is to provide an automatic folding assembly 100 for a seat table, which is applied to seats in automobiles, high-speed trains or airplanes. The table automatic folding assembly 100 is installed on the rear side of the seat backrest. By using the seat table automatic folding assembly, the seat can realize the automatic folding and automatic opening of the table relative to the backrest, and achieve intelligent automatic control.

[0031] Please refer to Figures 1 to 6 together, the seat table automatic folding assembly 100 includes:

[0032] A seat bracket 10 for installing and connecting to the rear side of the seat backrest;

[0033] A table frame 20 for installing and forming a table;

[0034] A sliding block 30, which is arranged to be able to slide up and down along the seat bracket 10 and is rotatably connected to the front side part of the table frame 20 adjacent to the seat bracket 10;

[0035] A driving mechanism 40, which is arranged on the seat bracket 10 and can drive the sliding block 30 to move; and,

[0036] A rotating link 50, the first end of the rotating link 50 is rotatably connected to the upper side part of the seat bracket 10, and the second end of the rotating link 50 is rotatably connected to the middle area of the table frame 20 in the front-rear direction.

[0037] In this embodiment, by driving the sliding of the sliding block 30 relative to the seat bracket 10 and the rotation relative to the table frame 20, the relative rotation of the table frame 20 relative to the seat bracket 10 is realized. Limited by the mutual connection between the sliding block 30 and the rotating link 50 and the seat bracket 10 and the table frame 20, the table frame 20 rotates and moves on a limited track, so as to realize the rotational folding or rotational opening relative to the seat bracket 10.

[0038] Furthermore, the seat support 10 is provided with a sliding groove 11 corresponding to the sliding block 30, and the sliding block 30 is driven by the driving mechanism 40 to slide in the sliding groove 11. In this embodiment, the sliding groove 11 matching the sliding of the sliding block 30 is provided on the seat support 10, and the shape of the sliding groove is not limited, as long as it is satisfied with limiting the sliding of the sliding block 30 in the up and down directions.

[0039] Furthermore, the chair support 10 includes a base plate 12 and an extension plate 13 extending from opposite sides of the base plate 12 facing away from the table board frame 20, the base plate 12 and the extension plate 13 enclose the sliding groove 11, the base plate 12 is provided with a strip groove 121 along the sliding groove 11, the sliding block 30 includes a base 31 received in the sliding groove 11 and a connecting portion 32 extending from the base 31 and passing through the strip groove 121, the connecting portion 32 is rotatably connected to the table board frame 20. Specifically, the connecting portion 32 is configured as two connecting pieces extending from the base 31, and the corresponding strip grooves 121 are also configured as two pieces, and the two connecting pieces are rotatably connected to the table board frame 20 respectively. This embodiment provides a connection structure of the sliding block 30 with the chair support 10 and the table board frame 20, the sliding groove 11 is surrounded by three sides, so that the sliding block 30 can be installed into the sliding groove 11 from an open side. It is understandable that the connection structure between the sliding block 30 and the seat frame 10 and the table frame 20 is not limited to this. For example, it can also be a sliding groove 11 surrounded by four sides, which is open at one end, and the sliding block 30 is installed into the sliding groove 11 through the opening at the end.

[0040] Furthermore, the driving mechanism 40 includes a driving motor 41 and a screw rod 42 that is transmission-connected to the driving motor 41. The screw rod 42 is arranged along the sliding groove 11. The base 31 is provided with a connecting hole 311 adapted to the screw rod 42. The interior of the connecting hole 311 is threadedly connected to the screw rod 42. In this embodiment, the driving mechanism 40 is configured such that the driving motor 41 drives the screw rod 42 to rotate. The screw rod 42 is threadedly matched with the sliding block 30, and the rotational motion of the screw rod 42 is converted into the linear motion of the sliding block 30 along the screw rod 42. Since the screw rod 42 has extremely high efficiency when it is in positive motion (rotational motion is converted into linear motion), a very small motor torque can generate a large linear thrust, so that a low-power driving motor 41 can be used, thereby avoiding the generation of large operating noise.

[0041] In addition, the screw rod 42 is a self-locking nut screw rod. When the table frame 20 is opened, the self-locking property of the screw rod 42 is utilized so that the table frame 20 can bear the heavy objects on the table without rotating and folding in the opposite direction.

[0042] Furthermore, the two extension plates 13 are respectively provided with opposite limiting grooves 131 along the sliding groove 11, and the base 31 is provided with limiting arms 312 adapted to the limiting grooves 131. In this embodiment, specifically, the limiting arms 312 are respectively extended from the four corners of the base 31, and the stability of the sliding of the sliding block 30 is further limited by the cooperation between the limiting grooves 131 and the limiting arms 312, thereby improving the control stability of the overall rotation structure.

[0043] Furthermore, the number of the rotating links 50 is set to two, which are respectively arranged at the two ends of the table frame 20, and the seat bracket 10 also includes a rotating shaft 14 arranged at the upper side and perpendicular to the rotating links 50, and the rotating links 50 are respectively rotatably connected to the table frame 20 and the rotating shaft 14. In this embodiment, by providing two opposite rotating links 50, the stability of the rotating structure is further improved.

[0044] Furthermore, at least one of the rotational connection between the sliding block 30 and the table frame 20, the rotational connection between the rotational link 50 and the table frame 20, and the rotational connection between the rotational link 50 and the seat bracket 10 is a hinged structure. In this embodiment, the stability of the rotational structure is achieved through the hinge, and all hinges use bearings, including but not limited to angular contact ball bearings and deep groove ball bearings, to achieve the effect of reducing noise and extending service life.

[0045] Please refer to Figure 5 Furthermore, a damping pad 60 is provided in the hinge structure. In this embodiment, the damping pad is provided to eliminate the virtual position of the table top caused by processing or assembly. Figure 5 When the table top is in a vacant position and shakes, any hinge will have a tendency to rotate, and the damping gasket 60 blocks this rotation tendency, thereby preventing the table top from being in a vacant position after opening, which affects the user experience.

[0046] Furthermore, the driving mechanism 40 includes a driving motor 41, a screw rod 42 connected to the driving motor 41, and an electronic control unit (ECU) connected to the driving motor 41. The screw rod 42 is arranged along the sliding direction of the sliding block 30. The sliding block 30 is provided with a connecting hole 311 adapted to the screw rod 42. The interior of the connecting hole 311 is threadedly connected to the screw rod 42. The ECU is used to control the movement of the driving motor 41, receive external power supply, receive external control signals, or send status signals to the outside, so as to realize the intelligent 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, so as to meet various intelligent needs.

[0047] Please refer to Figure 6 , further, the driving mechanism 40 further includes a worm 43 connected to the driving motor 41 and a worm gear 44 engaged with the worm 43, and the worm gear 44 is connected to the lead screw 42. In addition, both ends of the worm gear 44 are fixed to the housing 45 through bearings.

[0048] Further, the driving mechanism 40 further includes one of an angle sensor or a gyroscope, and the angle sensor or the gyroscope is used to monitor the rotation angle of the tabletop frame 20 and feedback it to the ECU, and the ECU controls the driving motor to move according to the rotation angle to control the tabletop frame 20 to maintain a horizontal position in the open state. It can be understood that when the tabletop frame 20 is in the folded state, the angle sensor or the gyroscope does not intervene in the work and only intervenes in the work after receiving the open command and control.

[0049] Please refer Figure 3 to Figure 4 and Figure 3 , as shown in the figure, when the tabletop frame 20 is in the folded state, when the driving motor 41 receives the "open" signal from the ECU, the driving motor 41 drives the lead screw 42 to rotate, and the lead screw 42 drives the slider 30 to move upward in translation, and the rotating link 50 and the tabletop frame 20 also move according to the designed position and trajectory, driving the tabletop frame 20 to open to the specified horizontal position, as shown in Figure 4 the figure.

[0052] The automatic folding assembly for the seat table board, the seat and the vehicle provided by the present utility model realize that the table board frame 20 rotates and folds or rotates and opens relative to the seat bracket 10 through the connection of the sliding block 30 and the rotating link 50 by setting the sliding block 30 to slide relative to the seat bracket 10 and rotate relative to the table board frame 20. The driving mechanism 40 drives the sliding block 30 to slide, thereby driving the table board frame 20 and the rotating link 50 to rotate. The automatic folding assembly 100 for the seat table board has a simple structure and realizes stable control of the rotation of the table board frame, thereby realizing the intellectualization of the seat and the vehicle, and providing a good use experience for users.
