The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0019] Example 1 See Figures 1-3 This embodiment provides a multifunctional tabletop assembly, including a linear module 1, a tabletop assembly 2, and a back panel assembly 3. The linear module 1 and the tabletop assembly 2 are located on both sides of the back panel assembly 3, and the support legs 21 on the tabletop assembly 2 pass through the through holes 22 opened on the back panel assembly 3 to be fixedly connected to the slide rails 11 on the linear module 1. The linear module 1 drives the tabletop assembly 2 to move downward to form a footrest, and the linear module 1 drives the tabletop assembly 2 to move upward to return to the tabletop.

[0020] It should be noted that the table assembly 2 has the same function as the table in existing vehicles, such as being able to fold and unfold. When unfolded, it can be used for rear passengers to work, eat, or store items. For example, the table assembly 2 is a four-bar linkage structure to perform the function of folding forward and unfolding backward. That is, the structure of the table assembly 2 in this embodiment is the same as that in the prior art. The difference is that the table assembly 2 in this embodiment is provided with a support leg 21, and the support leg 21 is fixedly connected to the linear module 1, for example, by screws to the slide rail 11 of the linear module 1.

[0021] See Figure 4 For example, the longitudinal section of the support leg 21 is V-shaped, and the opening of the V-shape faces the linear module 1; during use, the two inclined ends of the V-shape are connected to the mounting plate 23 at the same time, and the support leg 21 is installed on the linear module 1 through the mounting plate 23.

[0022] See Figure 1 , Figure 4 , Figure 5Furthermore, this embodiment also includes an electric switch 4, which is mounted on the side of the back panel assembly 3 where the linear module 1 is located. The electric switch 4 is connected to the wiring harness interface of the drive component 12 in the linear module 1 to control the movement of the linear module 1. For example, when the button on the electric switch 4 is pulled down, the linear module 1 and the table assembly 2 move down together, and the table assembly 2 can be used as a footrest to improve comfort. When the button on the electric switch 4 is pulled up, the linear module 1 and the table assembly 2 move up together, and the table assembly 2 can be used as an office table or a dining table.

[0023] In the specific implementation process, the linear module 1 is one of the following: a gear and rack linear module, a ball screw linear module, or a synchronous belt linear module.

[0024] See Figure 2 , Figure 3 , Figure 10 For example, the linear module 1 is a rack and pinion linear module. In this case, the linear module 1 further includes a rack 13, a linear guide rail 14, a gear 15, and a bracket 16. The rack 13 is fixed in the guide groove of the linear guide rail 14, the slide rail 11 is slidably connected to the linear guide rail 14, and the rack 13 is located in the space formed by the slide rail 11 and the linear guide rail 14. The output shaft of the drive member 12 is provided with the gear 15, and the gear 15 meshes with the rack 13 to drive the slide rail 11 to slide along the linear guide rail 14. The drive member 12 is mounted on the bracket 16. It should be noted that the linear module 1 The longitudinal section is H-shaped, and each vertical side of the H-shape corresponds to a fixed support leg 21. That is, the linear module 1 has two linear guide rails 14, two slide rails 11, two racks 13, and two gears 15, and one linear guide rail 14 corresponds to one slide rail 11, one rack 13, and one gear 15. It should be noted that the driving component 12 is a dual-output shaft motor, that is, each of the two output shafts is provided with a gear 15 to mesh with the rack 13 on the corresponding side, thereby driving the slide rail 11 to slide along the linear guide rail 14, so as to realize the table assembly 2 moving upward or downward.

[0025] It should be noted that the two ends of the bracket 16 are fixedly connected to the slide rail 11 on the corresponding side, and the drive member 12 is installed in the middle of the bracket 16. That is, the two ends of the bracket 16 are vertically connected to the linear guide rail 14 on the corresponding side, the drive member 12 is installed in the bracket 16, and the bracket 16, the drive member 12 and the back plate assembly 3 share the same vertical center line, which improves stability while ensuring uniform force distribution. The output shaft of the drive member 12 extends into the guide groove of the linear guide rail 14. At this time, the gear 15 is also located in the guide groove and meshes with the rack 13 for transmission.

[0026] See Figure 2 , Figure 4 For example, the table assembly 2 has two legs 21, and one leg 21 corresponds to a linear guide rail 14 in the linear module 1, which improves the stability of the table assembly 2 and facilitates the up and down movement of the table assembly 2.

[0027] See Figure 6 , Figure 9 In the specific implementation process, the back panel assembly 3 includes a back panel body 31 and a cover plate 32; two first mounting holes 33 are opened along the height direction of the back panel body 31, and the cover plate 32 is adapted and fixed in the first mounting holes 33; each first mounting hole 33 corresponds to a through hole 22, and the first mounting hole 33 communicates with the through hole 22. It should be noted that the back panel assembly 3 is used to connect and fix with external devices to accommodate the table panel assembly of this embodiment.

[0028] For example, the first mounting hole 33 is elongated, allowing the support leg 21 to pass through while the table assembly 2 moves along the height direction of the first mounting hole 33.

[0029] Furthermore, the through hole 22 is located on the side of the back plate body 31 away from the center, providing sufficient space for installation and facilitating operation.

[0030] Example 2 See Figures 4-9 This embodiment provides a chair, including the multifunctional table assembly described in Embodiment 1. It should be noted that this multifunctional table assembly is located on the back of the chair, and while having the functions of a conventional table, it can also be used as a footrest, making it more versatile and better suited to user needs.

[0031] Furthermore, this embodiment also includes a first side plate 5, a second side plate 6, and an upper connecting plate 7; the first side plate 5 and the second side plate 6 are symmetrically arranged on both sides of the upper connecting plate 7, and the two sides of the linear module 1 are respectively fixed to the first side plate 5 and the second side plate 6.

[0032] It should be noted that the first side plate 5, the second side plate 6, and the upper connecting plate 7 are all fixed to the main body of the seat back to install the table assembly onto the seat.

[0033] This embodiment is implemented as follows: When the electric switch 4 is turned on, the drive unit 12 operates and drives the gear 15 to rotate. The gear 15 meshes with the rack 13, thus causing the slide rail 11 and the bracket 16 to move simultaneously along the length of the linear guide rail 14. If it moves downwards, it can be used as a footrest (e.g.). Figure 7 If it moves upwards, it can be used as a regular tabletop (e.g. Figure 8 ).

[0034] Example 3 This embodiment provides a vehicle including the seat described in Embodiment 2. The structure of this embodiment does not require additional space inside the vehicle, thus improving the comfort of rear passengers. It is also simple in structure and easy to operate.

[0035] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
