[0041] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0042] A seat back table system according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0043] like Figure 1-5 As shown, the table system of the seat back 6 includes a table body 1; an adjustment component connected between the seat back 6 and the table body 1; and a driving member that drives the adjustment component to move to realize the rotation and movement of the table body 1 relative to the seat back 6.

[0044] According to the embodiment of the present invention, the table system of the seat back 6 is linked to the driving member and the adjustment component to adjust the rotation and movement of the table body 1 relative to the seat back 6, thereby achieving dual adjustment of the pitch angle and the fore-and-aft position of the table body 1, thereby meeting the needs of different users for the comfort of use of the table body 1 and the diversification of usage scenarios. When the angle of the seat back 6 changes, the user can drive the adjustment component through the driving member to adjust the angle of the table body 1 to a horizontal state or any other desired tilt angle, making it convenient for the user to watch videos, consult materials, etc. in a more comfortable posture, thereby improving the user's experience of using the table. The user can also drive the adjustment component through the driving member to adjust the fore-and-aft distance between the table body 1 and the human body, thereby meeting the needs of users of different body shapes and ages.

[0045] In some embodiments, the adjustment component includes: an angle adjustment mechanism 14 for adjusting the pitch angle of the table board body 1; and a displacement adjustment mechanism 12 for adjusting the front and rear position of the table board body 1.

[0046] Specifically, adjusting the pitch angle of the tabletop body 1 refers to adjusting the angle between the tabletop body 1 and the seat back 6, while adjusting the fore-aft position of the tabletop body 1 refers to adjusting the distance between the tabletop body 1 and the user. The separate design of the angle adjustment mechanism 14 and the displacement adjustment mechanism 12 allows for independent control of the pitch angle and fore-aft position, meeting the user's need for single adjustments. For example, to level the tabletop, the user only needs to activate the angle adjustment mechanism 14, while the displacement adjustment mechanism 12 remains stationary. To extend the tabletop, the user only needs to activate the displacement adjustment mechanism 12, simplifying the operation logic and facilitating user convenience.

[0047] In some embodiments, the angle adjustment mechanism 14 includes: an active link 3, including a first end and a second end, the first end is connected to the driving member, and the second end is connected to the table board body 1; a driven link 4, including a third end and a fourth end, the third end is connected to the seat back 6, and the fourth end is connected to the table board body 1.

[0048] like Figure 1-2 As shown, the first end of the active link 3 is fixedly connected to the driver, and the second end is rotationally connected to the tabletop body 1. The third end of the passive link 4 is rotationally connected to the seat back 6, and the fourth end is rotationally connected to the tabletop body 1. The active link 3, the passive link 4, the tabletop body 1, and the seat back 6 form a double rocker mechanism. The driver drives the active link 3 to rotate, and the passive link 4 rotates with it, thereby adjusting the angle of the tabletop body 1 relative to the seat back 6. This double rocker mechanism forms a stable mechanical linkage, ensuring smooth rotation of the tabletop body 1 during adjustment. The active link 3 is driven by the driver, while the passive link 4 transmits power through the connection points with the tabletop body 1 and the seat back 6, achieving precise control of the pitch angle of the tabletop body 1. Furthermore, the shapes of the active link 3 and the passive link 4 have been optimized, so that the tabletop body 1 is perpendicular to the seat back 6 when fully opened. That is, when the seat back 6 is vertical, the tabletop body 1 can still be horizontal, meeting user requirements.

[0049] In some embodiments, at least two active links 3 are spaced apart along the left and right directions of the seat back 6 ; at least two driven links 4 are spaced apart along the left and right directions of the seat back 6 ; the number of active links 3 is consistent with the number of driven links 4 .

[0050] like Figure 1 As shown, two active links 3 and two passive links 4 are spaced apart along the left and right sides of the seat back 6. When the driver drives the active links 3 to rotate, the forces on the left and right sides of the table board body 1 are balanced, ensuring the smooth rotation of the table board body 1. Three active links 3 and three passive links 4 can also be spaced apart along the left and right sides of the seat back 6. All active links 3 are uniformly driven by the driver. The increase in the number of active links 3 and passive links 4 further enhances the smooth rotation of the table board body 1. Increasing the number of active links 3 and passive links 4 will increase the size and cost of the entire seat back 6 table board system, so it is necessary to balance the stability and cost-effectiveness of the system.

[0051] In some embodiments, the angle adjustment mechanism 14 further includes: an elastic reset element connected between the driven link 4 and the seat back 6 .

[0052] Specifically, a preload is applied by the elastic reset element. This preload acts in the opposite direction of the tabletop body 1's opening. Once the tabletop body 1 is opened and its angle adjusted, the elastic reset element provides cushioning and positioning for the tabletop body 1, minimizing vibration during use and preventing angular deviation due to external impact. For example, when the driver stops operating, the elastic reset element's preload stabilizes the driven link 4, ensuring that the tabletop body 1 remains fixed at the set angle, enhancing safety.

[0053] In some embodiments, the elastic reset element is a torsion spring 5. Figure 1 As shown, the torsion spring 5 provides a preload in the direction opposite to the opening of the tabletop body 1. The helical structure of the torsion spring 5 also occupies a small space and provides uniform torque output, making it suitable for the compact space on the seatback 6. For example, the torsion spring 5 is installed at the connection point between the driven link 4 and the seatback 6. When the driving member rotates the active link 3, the torsion spring 5 deforms. After adjustment, the spring releases its elastic potential energy to help the tabletop body 1 maintain a stable angle.

[0054] In some embodiments, the displacement adjustment mechanism 12 includes: a sliding component 121 connected to the driving member and at least part of the angle adjustment mechanism 14; a guide component 123 adapted to the sliding component 121 and connected to the table top body 1.

[0055] like Figure 1 As shown, the sliding assembly 121 is connected to at least a portion of the angle adjustment mechanism 14. When the angle adjustment mechanism 14 is not moving, both the angle adjustment mechanism 14 and the sliding assembly 121 are stationary. When the driver drives the sliding assembly 121 to move relative to the guide assembly 123, the guide assembly 123 moves. The guide assembly 123 is fixedly connected to the tabletop body 1, ultimately achieving forward and backward displacement adjustment of the tabletop body 1 to meet the personalized needs of different users.

[0056] In some embodiments, the sliding assembly 121 is configured as a slider and the guide assembly 123 is configured as a rail. The combination of the slider and rail provides low-friction, high-precision linear motion, enabling precise adjustment of the front and rear displacement of the table body 1 to accommodate users of different body shapes or ages.

[0057] Optionally, the sliding assembly 121 may adopt a screw-nut structure, and the driving member drives the nut to move along the guide assembly 123 by rotating the screw, thereby pushing the table board body 1 to move forward and backward.

[0058] In some embodiments, the extension direction of the slide rail is consistent with the movement direction of the table top body 1 .

[0059] like Figure 1As shown, the slide rails are arranged along the front-to-back direction of the seat back 6, and the sliding direction of the table board body 1 is parallel to the extension direction of the slide rails, ensuring the linearity of the movement path, thereby reducing the lateral force during the adjustment process, avoiding deflection or jamming of the table board body 1 during movement, and improving the stability of the system.

[0060] In some embodiments, the adjustment assembly further includes: a connecting member 9 , and the sliding assembly 121 is connected to at least a portion of the angle adjustment mechanism 14 via the connecting member 9 .

[0061] like Figure 1-4 As shown, the sliding assembly 121 is fixedly connected to the connecting member 9, and the connecting member 9 is connected to at least part of the angle adjustment mechanism 14. The connecting member 9 serves as a connecting component between the angle adjustment mechanism 14 and the displacement adjustment mechanism 12, so that the angle adjustment mechanism 14 and the displacement adjustment mechanism 12 can influence and restrict each other to ensure the coordination of the movements of the two, and at the same time it is beneficial to reduce the overall volume of the table system and save space.

[0062] In some embodiments, the second end of the active connecting rod 3 is rotatably connected to the connecting member 9 , and the fourth end of the driven connecting rod 4 is rotatably connected to the connecting member 9 .

[0063] like Figure 1-4 As shown, the active link 3, the driven link 4, the seat back 6, and the connector 9 form a double rocker mechanism. The driving member drives the active link 3 to rotate, and the driven link 4 rotates with the active link 3, thereby achieving angle adjustment of the connector 9 relative to the seat back 6. The connector 9 is fixedly connected to the sliding assembly 121, which moves in conjunction with the guide assembly 123. The guide assembly 123 is fixedly connected to the table board body 1. That is, there is no relative rotation between the connector 9 and the table board body 1. When the angle of the connector 9 relative to the seat back 6 changes, the table board body 1 will also change relative to the seat back 6, ultimately achieving angle adjustment of the table board body 1.

[0064] Alternatively, as Figure 1 、 3 As shown, a groove is provided inside the connecting member 9, and the second end of the active connecting rod 3 and the fourth end of the driven connecting rod 4 are respectively rotatably connected to the groove inside the connecting member 9 to prevent the active connecting rod 3 and the driven connecting rod 4 from interfering with the connecting member 9 during rotation.

[0065] In some embodiments, at least two sliding assemblies 121 are spaced apart along the left and right directions of the seat back 6 ; at least two guide assemblies 123 are spaced apart along the left and right directions of the seat back 6 ; the number of sliding assemblies 121 and guide assemblies 123 is consistent.

[0066] like Figure 1As shown, two sliding assemblies 121 and two guide assemblies 123 are spaced apart along the left and right sides of the seat back 6. This ensures that the table top body 1 is subjected to balanced force during forward and backward movement, ensuring smooth movement of the table top body 1. Increasing the number of sliding assemblies 121 and guide assemblies 123 increases the size and cost of the entire seat back 6 table top system, thus balancing system stability and cost-effectiveness.

[0067] In some embodiments, at least two connecting members 9 are spaced apart along the left-right direction of the seat back 6 .

[0068] like Figure 1 As shown, two connecting members 9 are spaced apart along the left and right directions of the seat back 6. The two connecting members 9 are connected to the two sliding assemblies 121 one-to-one, the two connecting members 9 are connected to the two active connecting rods 3 one-to-one, and the two connecting members 9 are connected to the two driven connecting rods 4 one-to-one, so that the table board system of the entire seat back 6 is symmetrical on the left and right, thereby increasing the stability of the system.

[0069] In some embodiments, the driving member includes a first driving member and a second driving member; the first driving member is used to drive the angle adjustment mechanism 14; the second driving member is used to drive the displacement adjustment mechanism 12.

[0070] Specifically, the dual-drive design enables independent control of angle and displacement adjustment, meeting user needs for single adjustment. For example, a first drive, such as a rotary motor, drives the active connecting rod 3 to rotate via a gear train, while a second drive, such as a linear motor 122, drives the sliding assembly 121 to move via a lead screw nut. Users can drive either the first or second drive according to their needs. Alternatively, the second drive and angle adjustment mechanism 14 can be replaced entirely by a linear motor module.

[0071] In some optional embodiments, such as Figure 1-4As shown, the first driving member includes an angle adjustment motor 20, a coupling 21 and a rotating shaft 2. The angle adjustment mechanism 14 includes an active link 3, a driven link 4 and a torsion spring 5. A fixed plate 60 is fixedly connected to the seat back 6, and an upper bracket 62 and a lower bracket 61 are fixedly connected to the fixed plate 60. The upper bracket 62 and the lower bracket 61 are both provided with connecting holes, which are respectively used to rotatably connect the driven link 4 and the rotating shaft 2. Specifically, the output shaft of the angle adjustment motor 20 is fixedly connected to the rotating shaft through the coupling 21, and the rotating shaft passes through the hole of the lower bracket 61 on the fixed plate 60 to form a rotatable connection therewith. The rotating shaft is fixedly connected to the first end of the active link 3, and the second end of the active link 3 is rotatably connected to the connecting member 9; the fourth end of the driven link 4 is rotatably connected to the connecting member 9, and the third end of the driven link 4 is rotatably connected to the upper bracket 62 of the fixed plate 60. In practice, the active link 3, the driven link 4, the fixed plate 60, and the connector 9 form a double rocker mechanism. The angle adjustment motor 20 drives the rotating shaft 2 to rotate the active link 3, driving the second end of the active link 3 from bottom to top. The driven link 4 rotates in tandem with the active link 3, driving the fourth end of the driven link 4 from bottom to top, thereby adjusting the angle of the connector 9 relative to the seat back 6. The connector 9 never rotates relative to the tabletop body 1 and is positioned parallel to the tabletop body 1. Rotation of the connector 9 adjusts the angle of the tabletop body 1. A torsion spring 5 is installed between the driven link 4 and the fixed plate 60. Its preload force is opposite to the direction in which the tabletop body 1 opens, reducing vibration during use.

[0072] In some embodiments, the table top body 1 is a double-layer cover structure.

[0073] like Figure 1-2 As shown, the tabletop body 1 includes an upper cover 10 and a lower cover 11. The double-layer cover structure can enhance the strength and rigidity of the tabletop body 1. At the same time, space can be reserved between the upper cover 10 and the lower cover 11 to accommodate at least part of the angle adjustment mechanism 14 and the displacement adjustment mechanism 12. In addition, a snap groove 111 is provided on the lower cover 11 for forming a detachable fixed connection with the snap on the upper cover 10.

[0074] In some optional embodiments, such as Figure 1-4As shown, the second drive member includes a linear motor 122; the angle adjustment mechanism 14 includes a sliding assembly 121 and a guide assembly 123; the tabletop body 1 includes an upper cover 10 and a lower cover 11. The lower cover 11 is provided with a snap groove 111 for forming a fixed connection with the snap on the upper cover 10. The seat back 6 tabletop system also includes a connector 9. The second end of the active link 3 is rotationally connected to the connector 9, and the fourth end of the driven link 4 is rotationally connected to the connector 9. The connector 9 is also fixedly connected to the sliding assembly 121. The lower cover 11 provides support for the connector 9 and is not connected to the connector 9, facilitating the forward and backward movement of the tabletop body 1. The linear motor 122 can be installed in the sliding assembly 121, and the guide assembly 123 is fixedly connected to the lower cover 11. When the linear motor 122 drives the sliding assembly 121, the sliding assembly 121 moves relative to the guide assembly 123, which drives the tabletop body 1 to move forward and backward relative to the seat back 6. Specifically, when the first driving member stops working, the angle adjustment mechanism 14 does not move, that is, the connecting member 9 and the sliding assembly 121 do not move. When the linear motor 122 drives the sliding assembly 121, the sliding assembly 121 cannot move, so it drives the guide assembly 123 to move linearly, that is, drives the table board body 1 to move forward and backward. When the table board is not suitable, such as Figure 4 As shown, the first driving member drives the active connecting rod 3 to rotate, which drives the driven connecting rod 4 to rotate, and finally realizes the folding and storage of the table board body 1. The rotation direction of the active connecting rod 3 when the table board body 1 is opened is opposite to the rotation direction of the active connecting rod 3 when the table board body 1 is folded and stored.

[0075] In some embodiments, the seat back 6 table system further includes: a support bracket 13 rotatably disposed on the edge of the table body 1 .

[0076] like Figure 5 、 6 As shown, a rotatable support bracket 13 is also provided on the edge of the table body 1. The support bracket 13 provides an additional support point to prevent items on the table body 1 from shaking or tipping over during use. When the table body 1 is adjusted to tilt downward away from the seat back 6, the rotatable support bracket 13 is used to support mobile phones, tablets, books, etc., allowing users to read and watch movies in a more comfortable state, meeting their diverse usage needs. Damping can be provided between the support bracket 13 and the table body 1 to prevent abnormal noise during the rotation of the support bracket 13.

[0077] In some optional embodiments, such as Figure 6 As shown, the support bracket 13 can be connected to the table body 1 via a hinge axis. The user can manually flip out the bracket and rotate it to a suitable angle to place a mobile phone, tablet or book, improving the user experience. When not in use, the support bracket 13 can be embedded in the table body 1 to ensure the surface of the table body 1 is flat.

[0078] Optionally, the support bracket 13 is further provided with a positioning structure, and the support bracket 13 ensures that the support bracket 13 can be fixed at a specific angle after rotation through the positioning structure, such as a slot, to avoid accidental rebound.

[0079] In some embodiments, the seat back 6 table system further includes a control module 8 electrically connected to the drive element. Specifically, the control module 8 implements intelligent control of the drive element, thereby improving the automation level of the system.

[0080] In some embodiments, control module 8 includes a signal receiving unit for receiving user input, a data exchange unit for enabling data sharing, and an execution unit for controlling the driver. The signal receiving unit, such as a touch screen or physical buttons, allows users to customize parameter settings. The data exchange unit enables data sharing between multiple systems via a communication link, allowing for real-time access to more parameter information and enhancing the intelligent control of the desktop system.

[0081] In some embodiments, the signal receiving unit includes an adjustment button 7. Figure 7 As shown, the adjustment buttons 7 provide an intuitive physical interaction method. There are six physical buttons in the adjustment buttons 7, including a table top opening button 71, a table top retraction button 72, a table top forward rotation button 73, a table top backward rotation button 74, a forward movement button 75, and a backward movement button 76. The adjustment buttons 7 can be installed on the side of the seat to facilitate rear-seat users to adjust the pitch angle and fore-and-aft position of the table top body 1, improving user convenience.

[0082] In some embodiments, the data exchange unit can access seat back 6 angle information via the system communication bus. This real-time information, obtained via a communication bus (e.g., CAN or LIN), allows for dynamic linkage between the tabletop body 1 and the seatback 6, enhancing the user experience. For example, the control module 8 communicates with the system via the CAN bus and automatically adjusts the tabletop body 1's pitch angle based on the seatback 6 angle, achieving coordinated adjustment.

[0083] In some embodiments, the control module 8 is configured with an automatic leveling function. When the seat back 6 tilts backward, the system obtains the angle information of the seat back 6, and the control module 8 drives the driving member to move according to the preset algorithm to achieve precise control and automatically adjust the pitch angle of the table board body 1 to keep it horizontal; or the table board system detects the tilt angle of the table board body 1 through the sensor and drives the driving member to adjust it to a horizontal state. For example, when the table board tilts due to bumps during driving, the control module 8 automatically starts the leveling program to ensure the stability of the user experience. In addition, a one-touch leveling button can be set. By long pressing the start button, the angle fine-tuning or one-touch leveling function can be achieved. When it is inconvenient for the user to adjust or the adjustment angle is too large, the user can level the table board body 1 with one click, which is convenient for the user to use.

[0084] Another embodiment of the present invention provides a vehicle, comprising a vehicle body; a seat disposed in the vehicle body; and a table system such as any one of the seat backs 6 described above, mounted on the seat backs.

[0085] According to some embodiments of the present invention, the control module 8 of the seat back 6 table system is communicatively connected to the central control of the vehicle.

[0086] In some optional embodiments, the communication relationship between the table system control hardware of the seat back 6 is as follows: Figure 8 As shown, both the angle adjustment motor 20 and the linear motor 122 have encoders, and the control module 8 can obtain motor position information from the encoders. The control module 8 is also connected to the vehicle's central control system to obtain the current angle information of the seat back 6 from the vehicle's central control system. When the tabletop body 1 is in the stowed position, if the rear-seat user needs to use the small table, they can press the open button 71 to open the tabletop body 1. The tabletop control module 8 obtains the current angle information of the front-row seat back 6 from the vehicle's central control system, calculates the angle required to rotate the small tabletop to a horizontal position, and then controls the angle adjustment motor 20 to drive the tabletop body 1 to a horizontal position. If the rear-seat user wants to adjust the tabletop body 1 to a different angle, they can adjust it using the forward rotation button 73 and the backward rotation button 74. If the rear-seat user wants to adjust the distance between the tabletop body 1 and the user, they can adjust it using the forward movement button 75 and the backward movement button 76 to achieve a more comfortable use position. If the user needs to use a mobile phone or tablet to watch videos, read, etc., the support bracket 13 on the edge of the tabletop body 1 can be flipped out for support. Furthermore, when the tray table is in the open state, pressing the open button 71 again will adjust the tray table to a horizontal state. When the tray table is no longer needed, the close button 72 can be pressed to fold it up. The control module 8 calculates the number of pulse signals required to fold the tray table body 1 based on the information fed back by the encoders of the angle adjustment motor 20 and the linear motor 122, and outputs a pulse signal to control the motor to fold the tray table.

[0087] Optionally, the seat back 6 table system can be linked to the vehicle's central control system, such as the in-vehicle navigation or entertainment system, via control module 8, enabling more intelligent adjustments. For example, the user can directly control the expansion, angle, and position of the table body 1 through voice commands or the central control screen, enhancing the human-computer interaction experience.
