[0002] With the development of the vehicle industry, more and more functional requirements are being put forward for vehicles. The table board on the backrest has become more and more concerned, and passengers have higher expectations for the convenience of operation and adjustment of the table board behind the seat back.

[0003] In the prior art, the vehicle seat table is hingedly arranged on the back of the seat and the hinge is fixed. During use, the user needs to manually adjust the table to open and close it, which causes inconvenience to the user. Utility Model Content

[0004] In view of this, the utility model provides an electrically adjustable table top assembly, a seat and a vehicle to solve the problem that the existing table top has a fixed hinged position and needs to be manually adjusted by the user to open and close the table top during use, which is inconvenient to use.

[0005] In a first aspect, the utility model provides an electrically adjustable table top assembly, comprising:

[0006] The mounting plate has first rotation points on both sides in the width direction;

[0007] A sliding member is arranged along the width direction of the mounting plate and is adapted to move along the length direction of the mounting plate, and two ends of the sliding member protrude from two sides of the mounting plate in the width direction;

[0008] A table top is arranged opposite to the front side of the mounting plate, and has a free end and a rotating end. Both sides of the table top in the width direction are provided with a second rotating point located between the free end and the rotating end. The rotating end of the table top is rotatably connected to both ends of the sliding member.

[0009] Two connecting rods are respectively arranged on both sides of the table top in the width direction, one end of each connecting rod is rotatably connected to the corresponding first rotating point, and the other end of each connecting rod is rotatably connected to the corresponding second rotating point;

[0010] A driving mechanism, connected to the sliding member, and used to drive the sliding member to move along the length direction of the mounting plate;

[0011] The table top has an open state and a closed state. In the open state, the table top and the mounting plate are set at an angle and the sliding member moves close to the first rotation point. In the closed state, the table top and the mounting plate are abutted and the sliding member moves away from the first rotation point.

[0012] Beneficial effect: When the user needs to open the table board, the driving mechanism drives the sliding member to move along the length direction of the mounting plate toward the first rotation point. During the movement of the sliding member, the rotating end of the table board is driven to move toward the first rotation point. Since the second rotation point of the table board is connected to the first rotation point through two connecting rods, the two connecting rods rotate during the process of the rotating end of the table board approaching the first rotation point. The two connecting rods push the second rotation point of the table board to rotate around the rotating end of the table board, so that the table board and the mounting plate are set at an angle, and finally enter the open state, thereby realizing automatic control of the opening of the table board for the convenience of user use and improving the convenience of opening the table board. At the same time, during the process of the table board changing from the closed state to the open state, the rotating end of the table board gradually opens during the rising process, thereby avoiding interference between the table board and the user's legs and not affecting the user's leg placement space, thereby ensuring that the table board surface is at a higher position when the table board is in the open state, thereby improving the user experience.

[0013] When the user needs to close the table top, the driving mechanism drives the sliding member to move along the length direction of the mounting plate toward and away from the first rotation point. During the movement of the sliding member, the rotating end of the table top is driven to move toward and away from the first rotation point, causing the two connecting rods to rotate. The two connecting rods push the second rotation point of the table top to rotate around the rotating end of the table top, causing the table top to be attached to the mounting plate and enter a closed state, thereby realizing automatic control of the closing of the table top.

[0014] When the table top is in the open state, the second rotation point of the table top is supported by two connecting rods, and the rotating end of the table top is supported by the two ends of the sliding member, so that the rotating end of the table top is close to the mounting plate. The connection between the connecting rod, the table top and the sliding member forms a stable triangular support structure, which effectively enhances the load-bearing capacity of the table top. The structure is simple, and the driving process of the driving mechanism is smooth. The table top can be opened and closed smoothly, and the user experience is good.

[0070] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0071] In the related art, the vehicle seat table is hinged on the back of the seat and the hinge is fixed. During use, the user needs to manually adjust the table to open and close it, which causes inconvenience to the user.

[0072] In order to solve the above technical problems, the following Figures 1 to 15 , describing an embodiment of the utility model.

[0073] According to an embodiment of the present utility model, on the one hand, as Figures 1 to 10 As shown, an electrically adjustable table top assembly is provided, comprising a mounting plate 1, a sliding member 4, a table top 2, a connecting rod 3 and a driving mechanism 5.

[0074] Specifically, Figure 7 As shown, first rotation points 101 are provided on both sides of the mounting plate 1 in the width direction.

[0075] Specifically, Figures 5 to 7 As shown, the sliding member 4 is arranged along the width direction of the mounting plate 1 , and the sliding member 4 is suitable for moving along the length direction of the mounting plate 1 , and both ends of the sliding member 4 protrude from both sides of the mounting plate 1 in the width direction.

[0076] Specifically, Figures 5 to 7 As shown, the table top 2 is arranged opposite to the front side of the mounting plate 1, and the table top 2 has a free end 204 and a rotating end 202 (as shown in FIG. Fig. 9 As shown), a second rotation point 201 is provided on both sides of the table top 2 in the width direction, and the second rotation point 201 is located between the free end 204 and the rotation end 202. The rotation end 202 of the table top 2 is rotationally connected to the two ends of the sliding member 4.

[0077] Specifically, Figures 5 to 7 As shown, two connecting rods 3 are respectively arranged on both sides of the table top 2 in the width direction, one end of each connecting rod 3 is rotatably connected to the corresponding first rotation point 101, and the other end is rotatably connected to the corresponding second rotation point 201.

[0078] Specifically, Figure 5 As shown, the driving mechanism 5 is connected to the sliding member 4 , and the driving mechanism 5 is used to drive the sliding member 4 to move along the length direction of the mounting plate 1 .

[0079] The table top 2 has an open state and a closed state. In the open state (such as Figure 4 As shown), the table top 2 and the mounting plate 1 are arranged at an angle, and the sliding member 4 moves to a position close to the first rotation point 101, in the closed state (as shown Figures 5 to 7 As shown), the table top 2 is in contact with the mounting plate 1, and the sliding member 4 moves away from the first rotation point 101.

[0080] In this electrically adjustable table top assembly, when the user needs to open the table top 2, the driving mechanism 5 drives the sliding member 4 to move along the length direction of the mounting plate 1 toward the first rotation point 101. During the movement of the sliding member 4, the rotating end 202 of the table top 2 is driven to move toward the first rotation point 101. Since the second rotation point 201 of the table top 2 is connected to the first rotation point 101 through two connecting rods 3, the two connecting rods 3 rotate when the rotating end 202 of the table top 2 approaches the first rotation point 101, and the two connecting rods 3 push the second rotation point 201 of the table top 2 The rotating point 201 rotates around the rotating end 202 of the table top 2, so that the table top 2 is set at an angle with the mounting plate 1, and finally enters an open state, thereby realizing automatic control of the opening of the table top 2, so as to facilitate user use and improve the convenience of opening the table top. At the same time, in the process of the table top 2 changing from a closed state to an open state, the rotating end 202 of the table top 2 gradually opens during the rising process, thereby avoiding interference between the table top 2 and the user's legs and not affecting the user's leg placement space, thereby ensuring that the surface of the table top 2 is at a higher position when the table top 2 is in the open state, thereby improving the user's experience.

[0081] When the user needs to close the table top 2, the driving mechanism 5 drives the sliding member 4 to move along the length direction of the mounting plate 1 toward and away from the first rotation point 101. During the movement of the sliding member 4, the rotating end 202 of the table top 2 is driven to move toward and away from the first rotation point 101, so that the two connecting rods 3 rotate. The two connecting rods 3 push the second rotation point 201 of the table top 2 to rotate around the rotating end 202 of the table top 2, so that the table top 2 is attached to the mounting plate 1 and enters a closed state, thereby realizing automatic control of the closing of the table top 2.

[0082] When the table top 2 is in the open state, the second rotation point 201 of the table top 2 is supported by two connecting rods 3, and the rotating end 202 of the table top 2 is supported by the two ends of the sliding member 4, so that the rotating end 202 of the table top 2 is close to the mounting plate 1. The connection between the connecting rod 3, the table top 2 and the sliding member 4 forms a stable triangular support structure, thereby effectively enhancing the load-bearing capacity of the table top 2. The structure is simple, and the driving process of the driving mechanism 5 is smooth. The table top 2 can be opened and closed smoothly, and the user experience is good.

[0083] It should be noted that the first rotation point 101 on the mounting plate 1 is rotationally connected to the end of the connecting rod 3, which can be realized by a rotating member or by a hinge. In the embodiment of the present application, there is no specific restriction on the connection between the first rotation point 101 and the connecting rod 3. Similarly, there is no specific restriction on the connection between the second rotation point 201 on the table top 2 and the connecting rod 3.

[0084] Specifically, in the embodiment of the present application, there is no specific restriction on the shapes of the mounting plate 1 and the table top 2, and the shapes of the mounting plate 1 and the table top 2 can be set according to the specific usage scenario.

[0085] Specifically, the connecting rod 3 can be set as a straight rod or a curved rod. In the embodiment of the present application, there is no specific restriction on the shape of the connecting rod 3, and the shape of the connecting rod 3 should be selected according to the specific application scenario and requirements.

[0086] It should be noted that the driving mechanism 5 is not specifically limited in the present application, and the driving mechanism 5 may be selected from existing driving components, such as motor drive or cylinder drive.

[0087] In one embodiment, if Figures 5 to 7 As shown, the sliding member 4 is arranged on the back side of the mounting plate 1 , and first ear plates 401 are respectively arranged at both ends of the length direction of the sliding member 4 , and the first ear plates 401 are rotatably connected to the rotating end 202 through the rotating shaft 10 .

[0088] The sliding member 4 is arranged on the back of the mounting plate 1. When the table top 2 is in the closed state, the table top 2 and the mounting plate 1 can be as close to each other as possible, thereby reducing the volume of the electrically adjustable table top assembly. By arranging first ear plates 401 at both ends of the sliding member 4, the first ear plates 401 are connected to the rotating end 202 through the rotating shaft 10, so that the two ends of the sliding member 4 are rotatably connected to the rotating end 202, the structural stability of the entire assembly can be enhanced, vibration and shaking can be effectively reduced, and the table top 2 can be ensured to move smoothly during the opening and closing process.

[0089] It should be noted that the side of the mounting plate 1 facing the user is the front side, and the side facing away from the user is the back side.

[0090] Specifically, the first ear plate 401 and the rotating end 202 can be rotatably connected by snapping together. In the embodiment of the present application, no specific limitation is imposed on the manner in which the first ear plate 401 and the rotating end 202 are rotatably connected.

[0091] In one embodiment, if Figure 8 As shown, the sliding member 4 is further provided with a connecting portion 402 extending along one side of the length direction thereof and bent, and the connecting portion 402 is connected to the driving mechanism 5. By providing the bent connecting portion 402 on the sliding member 4, the sliding member 4 is connected to the driving mechanism 5 through the connecting portion 402, so that the installation of the sliding member 4 is easier. At the same time, the space occupied by the sliding member 4 can be effectively reduced by the bent connecting portion 402.

[0092] Specifically, a mounting hole can be opened on the connecting part 402, and the connecting part 402 is connected to the driving mechanism 5 through the mounting hole, or the connecting part 402 and the driving mechanism 5 can be connected by snap-fitting or fasteners. In the embodiment of the present application, no specific restriction is imposed on the connection method between the connecting part 402 and the driving mechanism 5.

In the open state, the connection between the first connecting section 301 and the second connecting section 302 is located below the tabletop of the tabletop.

[0094] The first connecting section 301 and the second connecting section 302 of the connecting rod 3 are connected at an angle. When the table top 2 is in the open state, since the connection between the first connecting section 301 and the second connecting section 302 is located below the table top of the table top, the area of ​​the extended surface of the table top 2 occupied by the second connecting section 302 can be reduced while ensuring the stability of the support of the table top 2, so that the surface of the table top 2 has a larger extension space, which can make it more convenient to place items.

[0095] Exemplary, combined Figure 4 and Fig.10 As shown, when the table top 2 is in the open state, the second connecting section 302 of the connecting rod 3 can be arranged parallel to the plane where the table top 2 is located. When the table top 2 is opened, the second connecting section 302 is located on the side of the table top 2 and does not protrude from the use surface of the table top 2, ensuring that the surface of the table top 2 has a larger extension space.

[0096] In one embodiment, if Figure 7 As shown, the first rotation point 101 is arranged near the upper end of the mounting plate 1. The first rotation point 101 is arranged near the upper end of the mounting plate 1, and when the table top 2 is in the open state, the sliding member 4 and the rotation end 202 of the table top 2 are as close to the upper end of the mounting plate 1 as possible, so that the use surface of the table top 2 is at a higher position, thereby improving the user experience.

[0097] In one embodiment, if Figures 1 to 4 As shown, it also includes a mounting shell 7, which is provided with an opening and a accommodating cavity connected to the opening, and the mounting plate 1 is located in the accommodating cavity. When the table top 2 is in a closed state, the table top 2 closes the opening. When the table top 2 is in an open state, the table top 2 extends out of the opening and is set at an angle to the mounting shell 7.

[0098] By installing the mounting plate 1 in the accommodating cavity of the mounting shell 7, when installing the electrically adjustable table board assembly, it is only necessary to install the mounting shell 7 on the back of the seat to complete the installation, thereby simplifying the installation steps and improving the installation efficiency. When the table board 2 is in the closed state, the table board 2 closes the opening, making the overall appearance of the electrically adjustable table board assembly more concise and improving the aesthetics. When the table board 2 is in the open state, by setting the table board 2 and the mounting shell 7 at a certain angle, the user can be more comfortable when using the table board 2. In addition, the mounting shell 7 provides good shielding and protection for the mounting plate 1, the sliding member 4, the driving mechanism 5 and other components, making the entire table board assembly concise in appearance.

[0099] Specifically, the embodiment of the present application does not impose any specific restrictions on the shape of the mounting shell 7, and the shape of the mounting shell 7 can be adaptively set according to the shape of the back of the seat, so that the mounting shell 7 can be installed on the back of the seat.

[0100] Specifically, the mounting plate 1 can be installed on the mounting shell 7 by fastener connection, or by snap-on connection. Any existing connection method can be selected as needed. In the embodiment of the present application, no specific restrictions are imposed on the connection method between the mounting plate 1 and the mounting shell 7.

[0101] In one embodiment, if Figure 3 and Figure 4 As shown, a storage box 9 is further provided below the opening of the mounting shell 7. The storage box 9 is openably arranged on the mounting shell 7, and a placement cavity (not shown in the figure) is reserved between the storage box 9 and the mounting shell 7.

[0102] By openably arranging a storage box 9 on the mounting shell 7, a placement cavity is left between the storage box 9 and the mounting shell 7. The arrangement of the storage box 9 can provide the user with more storage space, making it convenient for the user to store items in the placement cavity.

[0103] Specifically, a mezzanine layer may be provided on the storage box 9, and a placement cavity is formed between the mezzanine layer and the storage box 9, so that office supplies such as documents can be placed in the placement cavity.

[0106] By opening a first avoidance groove 203 near the rotating end of the table top 2, when the table top 2 is in a closed state, the first avoidance groove 203 of the table top 2 is partially located in the accommodating cavity of the area covered by the storage box 9. The first avoidance groove 203 is used to avoid the upper edge of the storage box. The first avoidance groove 203 is not exposed to the outside of the mounting shell 7, thereby ensuring the aesthetics of the electrically adjustable table top assembly. When the table top 2 is in an open state, the usable space on the surface of the table top 2 can be increased.

[0107] It should be noted that if a smaller table top 2 is required to be designed, the first avoidance groove 203 does not need to be provided near the rotating end of the table top 2 .

[0108] In one embodiment, if Figures 2 to 4 As shown, a baffle plate 8 is provided on the mounting shell 7 between the accommodating cavity and the opening, and a second avoidance groove 701 for movement of the connection between the sliding member 4 and the rotating end 202 is provided on both sides of the mounting shell 7 in the width direction of the baffle plate 8, and the table top 2 and the mounting plate 1 are separated by the baffle plate 8.

[0109] The shielding plate 8 separates the table top 2 from the mounting plate 1. When the table top 2 is in the open state, the shielding plate 8 can effectively shield the mounting plate 1, ensuring the overall beauty of the table top 2 in the open state. Second avoidance grooves 701 are provided on both sides of the shielding plate 8, so that the connection between the sliding member 4 and the rotating end 202 can slide and rotate smoothly and unimpeded, thereby improving the stability of the overall structure and the smoothness of use.

[0110] Specifically, a felt can be provided on the second avoidance groove 701. By providing the felt on the second avoidance groove 701, the connection between the sliding member 4 and the rotating end 202 can be shielded during the movement, thereby improving the overall aesthetics. The felt covering the second avoidance groove 701 can play a certain protective role, preventing dust, foreign matter or water stains from entering the second avoidance groove 701. In this way, damage and pollution to the connection between the sliding member 4 and the rotating end 202 can be reduced, and its service life can be extended.

[0111] Specifically, a circular groove 205 may be provided on the desktop of the table board 2 to facilitate placing a water cup in the circular groove 205. A wireless charger 206 may also be provided on the desktop of the table board 2 to facilitate wireless charging of electronic devices.

The light brightness or color of the multiple atmosphere lights may be combined at will, and in the embodiment of the present application, no specific limitation is imposed thereon.

[0113] In one embodiment, if Figure 6 and Figure 7 As shown, second ear plates 102 are provided on opposite sides of the mounting plate 1 in the width direction. The second ear plates 102 protrude toward the table top 2 , and a first rotation point 101 is provided on each second ear plate 102 .

[0114] By setting the second ear plate 102 on both sides of the mounting plate 1 in the width direction, the connecting rod 3 is rotatably connected to the first rotation point 101 on the second ear plate 102, so that the connecting rod 3 is rotatably connected to the mounting plate 1, the overall structural stability of the assembly can be enhanced, vibration and shaking can be effectively reduced, and the table top 2 can be ensured to move smoothly during opening and closing.

[0115] Specifically, the second ear plate 102 and the connecting rod 3 can be rotationally connected by a rotating member or by a snap-on connection. In the embodiment of the present application, no specific limitation is imposed on the rotational connection method between the second ear plate 102 and the connecting rod 3.

[0116] Specifically, the second ear plates 102 on both sides of the mounting plate 1 can be symmetrically arranged about the central axis of the mounting plate 1 .

[0117] In one embodiment, it also includes a guide rail 6 and a slider, which cooperates with the guide rail 6. The slider is suitable for moving along the length direction of the guide rail 6. The guide rail 6 extends along the length direction of the mounting plate 1 and is arranged on the mounting plate 1. The slider is arranged on the sliding member 4.

[0118] The slider is set on the sliding member 4. The cooperation between the guide rail 6 and the slider allows the slider and the sliding member 4 to move along the length direction of the guide rail 6, ensuring the smooth movement of the table top 2 during the opening and closing process.

[0119] Specifically, one or more guide rails 6 may be provided, and multiple guide rails 6 should be provided in parallel. In the embodiment of the present application, the number of guide rails 6 is not specifically limited.

[0120] Specifically, the slider can be set on the sliding member 4 through a fastener, and the slider can also be integrally formed with the sliding member 4. In the embodiment of the present application, no specific limitation is imposed on the connection method between the slider and the sliding member 4.

[0121] In one embodiment, if Figure 5 As shown, the driving mechanism 5 is provided with at least one, and the driving mechanism 5 includes a screw rod 501 and a rotating motor 502. The screw rod 501 is arranged along the length direction of the mounting plate 1, and the rotating motor 502 is connected to the screw rod 501. A nut is provided on the screw rod 501, and the nut is threadedly matched with the screw rod 501, and the nut is connected to the sliding member 4.

[0122] Since the sliding member 4 is connected to the screw rod 501, the screw rod 501 is driven to rotate by the rotating motor 502, so that the nut drives the sliding member 4 to move smoothly along the length direction of the screw rod 501, thereby driving the table top 2 to open or close. The structure is simple and easy to produce and manufacture.

[0123] Specifically, the rotating motor 502 may be an existing driving component such as an electric motor or a motor. In the embodiment of the present application, the type of the rotating motor 502 is not specifically limited.

[0124] There are several installation methods:

[0125] Example 1: Figures 11 to 13 As shown, two guide rails 6 can be provided, and one screw rod 501 and one rotary motor 502 are provided. The screw rod 501 can be provided between the two guide rails 6 or overlap the path of the guide rail 6 .

[0126] Example 2: Figure 14 to Figure 15 As shown, two guide rails 6 , two lead screws 501 and two rotary motors 502 are provided, each rotary motor 502 is connected to a corresponding lead screw 501 , and each lead screw 501 overlaps with the path of the corresponding guide rail 6 .

[0127] Example 3: Fig.15 As shown, the sliding member 4 can be provided in two pieces, and the two sliding members 4 are respectively provided on two guide rails 6 and move synchronously.

[0128] In one embodiment, at least one driving mechanism 5 is provided, and the driving mechanism includes a linear motor (not shown in the figure), and the slider is connected to the linear motor.

[0129] The slider is driven by a linear motor to move along the length direction of the guide rail 6, so that the slider drives the sliding member 4 to move smoothly along the length direction of the guide rail 6, thereby driving the table top 2 to open or close. The structure is simple and easy to produce and manufacture.

[0130] In one embodiment, it also includes a controller and a physical button, a touch button or a voice recognition module (not shown in the figure), the controller is electrically connected to the physical button, the touch button or the voice recognition module, and the controller is electrically connected to the driving mechanism 5, and is used to control the driving mechanism to drive the table top 2 to switch between an open state and a closed state according to the input signal of the physical button, the touch button or the voice recognition module.

[0131] By operating physical buttons or touching buttons, users can conveniently control the opening and closing of the table top 2. The controller can automatically adjust the operation of the driving mechanism 5 according to the user's instructions to realize the switching of the table top 2 between the open state and the closed state, thereby improving the convenience and efficiency of operation.

[0132] The controller is connected to the voice recognition module. When the user issues a voice command such as "open the table top" or "close the table top", the voice recognition module inputs the command and sends the command to the controller. The controller drives the table top to open or close according to the command input by the voice recognition module, thereby realizing a convenient voice control function.

[0133] Specifically, the embodiment of the present application does not impose any specific restrictions on the location of the physical buttons and touch buttons. For example, the physical buttons or touch buttons can be set on the mounting shell 7 or on the door handle, etc.

[0134] Specifically, the controller may be an existing controller such as a PLC (programmable logic controller), a microcontroller, a computer control system, or a vehicle controller. In the embodiments of the present application, no specific limitation is imposed on the type of controller.

[0135] For example, taking the car controller as an example, the user can issue commands such as "open the left table panel", "open the right table panel", "close the left table panel" or "close the right table panel", and the car controller drives the corresponding table panel to open or close according to the commands input by the voice module.

[0136] In one embodiment, it also includes a level detector, which is arranged in the table top 2 and is used to detect the inclination angle of the table top 2 relative to the horizontal plane. The controller is electrically connected to the level detector, and controls the driving mechanism 5 to drive the table top 2 to adjust to a horizontal state according to the detection information of the level detector in the open state.

[0137] A level detector is set inside the table top 2 to detect the inclination angle of the table top 2 relative to the horizontal plane. When the table top 2 is in the open state, when the inclination angle of the table top 2 is forced to change (for example, the seat adjustment causes the inclination angle of the table top to change), the level detector will detect the information of the inclination angle of the table top 2 and send it to the controller. The controller controls the driving mechanism 5 to drive the table top 2 to adjust to a horizontal state according to the detection information of the level detector, thereby realizing adaptive horizontal state adjustment of the table top 2.

[0138] Exemplarily, the table top 2 is installed on the driver and front passenger seats. When the table top 2 is in the open state and the driver and front passenger seats adjust their angles, the level detector will detect the inclination angle of the table top 2 and send the information to the controller. The controller controls the driving mechanism 5 to drive the table top 2 to adjust to a horizontal position according to the feedback information from the level detector for user convenience.

[0139] The working principle of the electric adjustable table top assembly in this embodiment is described as follows:

[0140] 1) Install the electrically adjustable table assembly on the vehicle seat:

[0141] The mounting plate 1 is mounted on the mounting shell 7. When installing the electric adjustable table board assembly, the installation can be completed by only mounting the mounting shell 7 on the back of the seat, which is convenient for installation.

[0142] 2) The movement process of the table top 2 from the closed state to the open state:

[0143] The controller is controlled by physical buttons or touch buttons to make the rotating motor 502 rotate in the forward direction. The rotating motor 502 drives the screw rod 501 to rotate, thereby driving the sliding member 4 to move along the length direction of the mounting plate 1 toward the first rotating point 101. During the movement of the sliding member 4, the rotating end 202 of the table board 2 is driven to move toward the first rotating point 101. Since the second rotating point 201 of the table board 2 is connected to the first rotating point 101 through two connecting rods 3, the two connecting rods 3 rotate when the rotating end 202 of the table board 2 approaches the first rotating point 101. The two connecting rods 3 push the second rotating point 201 of the table board 2 to rotate around the rotating end 202 of the table board 2, so that the table board 2 is set at an angle to the mounting plate 1 and enters an open state.

[0144] 3) The movement process of the table top 2 from the closed state to the open state:

[0145] The controller is controlled by physical buttons or touch buttons to make the rotating motor 502 rotate in the opposite direction. The rotating motor 502 drives the screw rod 501 to rotate, thereby driving the sliding member 4 to move along the length direction of the mounting plate 1 toward and away from the first rotating point 101. During the movement of the sliding member 4, the rotating end 202 of the table board 2 is driven to move toward and away from the first rotating point 101, causing the two connecting rods 3 to rotate. The two connecting rods 3 push the second rotating point 201 of the table board 2 to rotate around the rotating end 202 of the table board 2, so that the table board 2 is attached to the mounting plate 1 and enters a closed state.

[0146] According to an embodiment of the present invention, on the other hand, a seat is provided, including a seat body and an adjustable table board assembly, wherein a mounting plate 1 is arranged on the back side of the seat body.

[0147] In this chair, when the table top 2 changes from a closed state to an open state, the rotating end 202 of the table top 2 gradually opens as it rises, thereby avoiding interference between the table top 2 and the user's legs and not affecting the user's leg placement space, ensuring that the surface of the table top 2 is in a higher position when the table top 2 is in the open state, thereby improving the user's experience.

[0148] Specifically, the seat may be a vehicle seat, an airplane seat, an office seat, etc. In the embodiments of the present application, the type of seat is not specifically limited.

[0149] According to an embodiment of the present utility model, on the other hand, Figures 1 to 15 As shown, a vehicle is also provided, comprising a vehicle body and a seat.

[0150] Specifically, the seat is installed in the vehicle body.

[0151] In this vehicle, when the table top 2 is in the open state, the second rotation point 201 of the table top 2 is supported by two connecting rods 3, and the rotating end 202 of the table top 2 is supported by the two ends of the sliding member 4, so that the rotating end 202 of the table top 2 is close to the mounting plate 1, and the connection between the connecting rod 3, the table top 2 and the sliding member 4 forms a stable triangular support structure, thereby effectively enhancing the load-bearing capacity of the table top 2.

[0152] Specifically, the vehicle may be an existing vehicle such as a car, a bus, a high-speed train, etc. In the embodiments of the present application, the type of vehicle is not specifically limited.
