[0076] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0077] See also Figures 1A-1C , Figure 1A is a schematic diagram of the state of the table board body of the smart table board provided in some embodiments of the present application in the recycling mode, Figure 1B is a schematic diagram of the state of the table board body of the smart table board provided in some embodiments of the present application in the projection mode, Figure 1C is a schematic diagram of the state of the smart table board body in the storage mode provided by some embodiments of the present application. Figure 2 , Figure 2 This is a structural schematic diagram of a smart table top provided in some embodiments of the present application, in which the table top body is in projection mode.

[0078] The smart table 10 includes a table body 11 and a projection device 12. The table body 11 has at least a recycling mode, a storage mode and a projection mode, and the table body 11 can be rotated to different positions to switch between the recycling mode, the storage mode and the projection mode. The projection device 12 is located on one side of the table body 11, wherein when the table body 11 is in the projection mode, the projection screen of the projection device 12 is projected onto the table body 11. Therefore, the smart table 10 can realize the storage function and the projection function, and the multifunctional smart table 10 can meet the various needs of users.

[0079] In some embodiments, the smart table 10 is applied to a seat 20, and the seat 20 includes a seat back 21. The smart table 10 in the present application can also be applied to other fields, and the present application does not limit this. For example, the smart table 10 can be applied to other mounting parts.

[0080] In some embodiments, the table top body 11 may also have other modes, which is not limited in the present application.

[0081] In some embodiments, Figure 2 and Figure 1A As shown, the back of the seat back 21 has a receiving groove 210. When the table board body 11 is in the recovery mode, the table board body 11 is partially received in the receiving groove 210. When not in use, the table board body 11 fits the back of the seat 20, which can reduce the space occupied by the rear passengers in the car.

[0082] like Figure 1C As shown, when the table board body 11 is in the storage mode, the table board body 11 extends in a direction away from the seat back 21, and the extension direction of the table board body 11 is parallel to the first direction. Figure 1B As shown, when the table top body 11 is in the projection mode, the extension direction of the table top body 11 is inclined relative to the first direction. For example, at this time, the angle between the plane direction of the table top body 11 and the first direction is less than 60°. This is more conducive to users operating on the surface of the table top body 11, and also convenient for users to watch movies projected on the table top body 11.

[0083] It should be noted that the table board body 11 in the embodiment of the present application can be rotated to different positions relative to the seat back 21, which means that the table board body 11 can be rotated so that the angle between it and the seat back 21 is any angle between 0° and 180°, that is, the table board body 11 can stay at a position corresponding to any angle. Among them, the recycling mode, the storage mode and the projection mode correspond to one of the positions of the table board body 11 relative to the seat back 21 respectively.

[0084] In some embodiments, the table body 11 and the projection device 12 are respectively fixedly mounted on mounting parts, such as the back of a seat back 21, and for easy viewing, the projection device 12 is located above the table body 11, and the upper surface of the table body 11 is the projection receiving surface.

[0085] See also Figure 3 , Figure 3 is a schematic diagram of the side structure of the smart table provided in some embodiments of the present application. It should be noted that: Figure 3 The projection device 12 is not shown, and Figure 3 The center table board body 11 is in a retracted state. Figure 4-6 , Figure 4 is a schematic diagram of an exploded structure of a driving mechanism provided in some embodiments of the present application, Figure 5 is a schematic diagram of the structure of the table board body and the motion device provided in some embodiments of the present application, Figure 6It is a structural schematic diagram of the connection between the motion device and the driving mechanism provided in some embodiments of the present application.

[0086] The smart table top 10 may further include a driving mechanism 13 , which is connected to the table top body 11 , and is used to drive the table top body 11 to be in the recycling mode, the storage mode or the projection mode.

[0087] In some embodiments, the smart table 10 further includes a motion device 14, which is connected to a side of the table body 11 away from the projection receiving surface. The motion device 14 is movably connected between the driving mechanism 13 and the table body 11. That is, the driving mechanism 13 drives the motion device 14 to move, and the motion device 14 drives the table body 11 to move together, so that the table body 11 is in different positions.

[0088] like Figure 3 As shown, the smart table board 10 also includes a first shell 15, a second shell 16 and a third shell 17. The first shell 15, the second shell 16 and the third shell 17 can be installed inside the mounting member (such as the seat back 21), the second shell 16 is connected to the first shell 15, and the third shell 17 is connected to the second shell 16. The driving mechanism 13 is installed inside the first shell 15, and the motion device 14 is partially hidden inside the second shell 16. In this way, the motion device 14 and the driving mechanism 13 are assembled separately, which can improve the production efficiency of the product.

[0089] In some embodiments, the driving mechanism 13 includes a driving component 131 and a transmission component, and the transmission component is connected between the driving component 131 and the motion device 14 .

[0090] In some embodiments, the transmission assembly includes a first transmission member 132 and a second transmission member 133 , wherein the first transmission member 132 is movably connected to the driving assembly 131 , and the second transmission member 133 is movably connected between the motion device 14 and the first transmission member 132 .

[0091] Specific examples, such as Figure 4 and Figure 6 As shown, the driving assembly 131 includes a driving motor 1311 and a worm 1312, and the worm 1312 is mounted on the motor shaft of the driving motor 1311. The first transmission member 132 includes a gear worm, and the gear of the gear worm is meshed with the worm 1312. The second transmission member 133 includes a double gear, and the double gear includes a first gear 1331 and a second gear 1332, and the first gear 1331 is meshed with the worm 1312 of the gear worm.

[0092] like Figure 5 and Figure 6 As shown, the motion device 14 includes a driven gear 141, and the second gear 1332 is meshed with the driven gear 141 of the motion device 14, and the driven gear 141 is arc-shaped.

[0093] In some embodiments, the second housing 16 has a slide groove, and the motion device 14 further includes a sliding assembly 142 connected to the driven gear 141, and the sliding assembly 142 is slidably connected to the slide groove. Thus, the driving mechanism 13 can drive the driven gear 141 to move, thereby driving the table board body 11 to move. During the movement of the motion device 14, the sliding assembly 142 is slidably connected to the slide groove, so that the motion device 14 can achieve stable movement.

[0094] Specific examples, such as Figure 5 As shown, the sliding assembly 142 includes a first guide rail 1421 and a second guide rail 1422 , and the first guide rail 1421 and the second guide rail 1422 are respectively connected to the slide groove in a sliding manner. The driven gear 141 is arranged between the first guide rail 1421 and the second guide rail 1422 .

[0095] The moving device 14 is composed of two guide rails and a driven gear 141. The driven gear 141 can be an irregular gear. The irregular gear movement drives the two guide rails to move on the slide groove, so as to realize the change of the mode of the table board body 11. The double guide rail structure can make the table board body 11 move smoothly, and also play a role in supporting the table board body 11.

[0096] In some embodiments, the motion device 14 may further include a mounting seat 143 and a support member 144 , the sliding assembly 142 is mounted on the mounting seat 143 , the mounting seat 143 is mounted on the support member 144 , and the side of the table top body 11 away from the projection receiving surface is mounted on the support member 144 .

[0097] See also Figure 7 , Figure 7 It is a schematic diagram of the structure of the table top body and the controller provided in some embodiments of the present application.

[0098] In some embodiments, the smart table 10 further includes a controller 30, which is disposed inside the table body 11. Figure 7 Only one setting method of the controller 30 is provided, and the present application does not limit the specific position of the controller 30. The controller 30 is used to control the projection device 12 to project the projection image onto the projection receiving surface of the table board body 11 in the projection mode. It can be understood that the controller 30 is electrically connected to the projection device 12.

[0099] In another embodiment, the controller 30 may also be disposed inside a mounting member (e.g., a table or chair backrest), and the controller 30 and the projection device 12 may be connected by wire or wirelessly. In some embodiments, the smart table 10 includes a sensing device 112, which is disposed inside the table body 11. The sensing device 112 receives a touch signal and sends the touch signal to the controller 30 or the driving mechanism 13, and the controller 30 also performs a corresponding function in response to the touch signal received by the table body 11.

[0100] In some embodiments, the table top body 11 includes a base layer 111 , the table top body 11 includes a projection receiving surface, and the sensing device 112 is disposed on a side of the base layer 111 close to the projection receiving surface.

[0101] The sensing device 112 is used to sense the position touched by the user and provide feedback. The sensing device 112 can be attached or injection molded to form an integral part with the base layer 111 .

[0102] In some embodiments, the controller 30 includes a processing module, a generating module and a sending module, the processing module receives and processes the touch signal, the generating module receives the signal processed by the processing module to generate image data, and the sending module sends the image data to the projection device 12. The projection device 12 generates a projection screen (or display interface) after processing the image data, and projects the projection screen onto the table board body 11, and displays interfaces such as a music control interface, an image selection interface, and a seat control interface.

[0103] In some embodiments, the touch signal may include a first type of touch signal, and the driving mechanism 13 receives the first type of touch signal and drives the table top body 11 to move.

[0104] As a specific example, the first type of touch signal includes a finger sliding signal. When the sliding signal is detected once, the driving mechanism 13 drives the motion device 14 to control the table top body 11 to switch from one mode to another mode.

[0105] For example, when the projection mode is needed, the driving mechanism 13 of the table board body 11 can be awakened by swiping the table top with a finger, and the table board body 11 can enter the projection mode, and the table board body 11 can receive the image on the projection device 12. Then, by swiping the table top with a finger, the table board body 11 will move further, parallel to the bottom plate of the car (horizontally set), and some items can be placed. Finally, if the table board body 11 needs to be retracted and the table top is slid again with a finger, the table board body 11 will be retracted, that is, switched to the recovery mode.

[0106] In some embodiments, the touch signal further includes a second type of touch signal, and the controller 30 receives the second type of touch signal and performs a corresponding operation. The second type of touch signal includes a pressing signal of a virtual button displayed on the projection screen, and by clicking the corresponding virtual button, the passenger can change songs, watch movies, adjust the seat position, etc. in the projection mode.

[0107] In some embodiments, the table top body 11 further includes a covering layer 113 , and the covering layer 113 is disposed on a side of the sensing device 112 away from the base layer 111 , and a surface of the covering layer 113 away from the sensing device 112 is the projection receiving surface.

[0108] In some embodiments, the material of the covering layer 113 is the same as the material of the back of the seat back 21 (the surface connected to the table body 11), so as to make the overall interior of the car more beautiful. For example, the covering layer 113 can be made of leather, and the leather covering layer can also be selected according to user needs or surrounding interior decoration.

[0109] In some embodiments, the table board body 11 has a groove on one side away from the projection receiving surface or the sensing device 112, and the table board body 11 further includes a support layer 114, which is disposed in the groove and can enhance the rigidity of the table board body 11. The support layer 114 can be made of steel plate.

[0110] In some embodiments, the table top body 11 may further include a vibration motor 115 , which may be installed on the base layer 111 to provide vibration feedback to the user, so that the user can clearly know that the action is being performed, thereby avoiding multiple accidental touches by the user.
