[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0027] See Figures 1 to 6 This application provides a folding table and its automobile, which can solve the problem of the limited size of the table in the width direction of the vehicle body in the related technology, which affects the user experience.

[0028] As user demands continue to increase, vehicles not only need to offer excellent handling and driving experience, but also need to function as an extension of the workplace and home. When passengers need to read, write, or work during their journey or while resting, the table provides a comfortable experience, serving as a place to put books, drinks, mobile phones, laptops, snacks, and other items. However, due to the limitations of the sub-dashboard structure, the existing table's dimensions in the vehicle's width direction are restricted, requiring both driver and front passenger to tilt towards one side, thus affecting the user experience.

[0029] To address the issue of the limited dimensions of the tabletop in the vehicle's width direction, which affects the user experience, this application provides a folding tabletop, characterized in that it includes: a lifting base 1 and a tabletop structure 2. The tabletop structure 2 includes a support plate 20, an extension plate 21, and a folding plate 24. The support plate 20 is connected to the lifting base 1. The tabletop structure 2 has a first state, a second state, and a third state. When the tabletop structure 2 is in the first state, the support plate 20, the extension plate 21, and the folding plate 24 overlap along the vehicle's height direction. When the tabletop structure 2 is in the second state, the extension plate 21 unfolds relative to the support plate 20 along the vehicle's width direction, and the folding plate 24 overlaps with one of the extension plate 21 and the support plate 20 along the vehicle's height direction. When the tabletop structure 2 is in the third state, the extension plate 21 and the folding plate 24 unfold relative to the support plate 20 along the vehicle's width direction.

[0030] In this application, the folding table can be folded up and stowed away. Under the same layout space, the width of the folding table can be designed according to the maximum width of the sub-dashboard. The table structure 2 has three states. The table structure 2 can be extended along the width direction of the vehicle body so that the table structure 2 reaches the middle position between the driver and the front passenger, making it more convenient and comfortable to use.

[0031] The device is fixed to the body sheet metal via the lifting base 1, and can be hidden inside the sub-dashboard when not in use.

[0032] The lifting base 1 includes: a mounting base 10, a lower bracket 11 and an upper bracket 13. The lower bracket 11 is fixedly connected to the mounting base 10. The upper bracket 13 is connected to the lower bracket 11 through a drive structure. A support plate 20 is connected to the top of the upper bracket 13.

[0033] Specifically, the drive structure includes a motor, a transmission sleeve, and a lifting screw 12. One end of the motor output shaft is connected to the transmission sleeve, which is fitted onto the outer circumferential surface of the lifting screw 12 and threadedly connected to it. When the motor operates, it drives the transmission sleeve to rotate. When the transmission sleeve rotates clockwise, the lifting screw 12 moves upward, causing the upper support 13 to rise; when the transmission sleeve rotates counterclockwise, the lifting screw 12 moves downward, causing the upper support 13 to descend. The support plate 20 is fastened to the upper support 13 with multiple bolts. The upper support 13 and all structures mounted on it move up and down together via the lifting screw 12.

[0034] To make the upper support 13 more stable during movement, a guide rail is provided on the surface of the lower support 11. Correspondingly, a limiting rod is provided on the upper support 13, and the limiting rod is slidably connected to the inside of the guide rail. Taking the use of the front passenger as an example, the process of using the folding table is as follows: First, the lifting screw 12 is driven by the motor to rise, and the upper support 13 moves upward to raise the table structure 2 in the first state to a height suitable for the use of the driver and passengers. Then, the state of the table structure 2 is manually adjusted according to the actual situation: when the table structure 2 is adjusted to the second state, the extension plate 21 is unfolded relative to the support plate 20 along the width direction of the vehicle body; when the table structure 2 is adjusted to the third state, the extension plate 21 and the folding plate 24 are unfolded relative to the support plate 20 along the width direction of the vehicle body, thus forming a table structure 2 that can be used by passengers to place boxed lunches for eating or to place laptops for working.

[0035] In some possible embodiments, when the table structure 2 is in the second state, the extension plate 21 unfolds relative to the support plate 20 along the vehicle width direction, and the folding plate 24 overlaps with the extension plate 21. In this embodiment, when the table structure 2 is in the first state, the extension plate 21 is located at the top of the support plate 20, and the folding plate 24 is located at the top of the extension plate 21. When the table structure 2 changes from the first state to the third state, the extension plate 21 unfolds horizontally on the support plate 20, and the folding plate 24 unfolds by folding on the extension plate 21.

[0036] In some other possible embodiments, when the table structure 2 is in the second state, the extension plate 21 unfolds relative to the support plate 20 along the width direction of the vehicle body, and the folding plate 24 overlaps with the support plate 20. In this embodiment, when the table structure 2 is in the second state, the folding plate 24 is located at the top of the support plate 20, and the extension plate 21 is located at the top of the folding plate 24. When the table structure 2 changes from the first state to the third state, the extension plate 21 unfolds horizontally on the folding plate 24, and the folding plate 24 unfolds by folding on the support plate 20.

[0037] Furthermore, in some possible embodiments, the support plate 20 is rectangular, and the extension plate 21 is a U-shaped structure. The inner wall of the extension plate 21 is slidably connected to the side of the support plate 20. When the table structure 2 is in the first state, the support plate 20 is located inside the U-shaped cavity of the extension plate 21. In this embodiment, when the table structure 2 is in the second state, the folding plate 24 is located at the top of the extension plate 21. When the table structure 2 changes from the first state to the third state, the support plate 20 unfolds horizontally, and the folding plate 24 unfolds folded on the extension plate 21.

[0038] The above embodiments are merely various possible implementations of the embodiments of this application, and the embodiments of this application are not limited thereto.

[0039] Taking the tabletop structure 2 in the first state, with the extension plate 21 located at the top of the support plate 20 and the folding plate 24 located at the top of the extension plate 21 as an example, based on the above embodiment, in this embodiment, the extension plate 21 is slidably connected to the support plate 20 through the connecting hinge 22. When the tabletop structure 2 is in the second or third state, the top of the extension plate 21 and the top of the support plate 20 are on the same horizontal plane.

[0040] Furthermore, a first guide rail is provided on the side of the support plate 20, and a second guide rail is provided on the side of the extension plate 21; the two ends of the connecting hinge 22 are slidably connected to the first guide rail and the second guide rail respectively. When the table structure 2 is in the first state, that is, the extension plate 21 is located at the top of the support plate 20, and the connecting hinge 22 is in a vertical state; when the table structure 2 is in the second or third state, that is, the extension plate 21 is located on one side of the support plate 20, and the connecting hinge 22 is in a horizontal state, so that the top of the extension plate 21 and the top of the support plate 20 are on the same horizontal plane.

[0041] The support plate 20 and the extension plate 21 are connected by a connecting hinge 22. Both the support plate 20 and the extension plate 21 consist of upper and lower parts. A first guide rail is formed between the upper and lower parts of the support plate 20, and a second guide rail is formed between the upper and lower parts of the extension plate 21. The connecting hinge 22 includes two connecting shafts and a washer. The two connecting shafts are slidably connected within the first and second guide rails, respectively. The washer is connected between the two connecting shafts and is rotatably connected to them. The two connecting shafts of equal length are placed parallel to each other, and their ends are connected and locked by two figure-eight-shaped washers. The figure-eight-shaped washers can rotate around their respective connecting shafts, and silicone oil damping is provided between the washers and the connecting shafts. The two connecting shafts of the connecting hinge 22 are respectively sandwiched between the upper and lower parts of the support plate 20 and the extension plate 21, realizing the guiding function of the guide rails and simultaneously connecting the support plate 20 and the extension plate 21. When the tabletop structure 2 is in the first state, the connecting hinge 22 is in a vertical state so that the extension plate 21 can be stacked on the top of the support plate 20; when the tabletop structure 2 is in the second or third state, the connecting hinge 22 is in a horizontal state so that the top of the extension plate 21 and the top of the support plate 20 are on the same horizontal plane.

[0042] Based on the above embodiments, in this embodiment, the folding plate 24 is connected to the extension plate 21 through the fixing plate 23. Specifically, the extension plate 21 is provided with the fixing plate 23, and one end of the fixing plate 23 is hinged to the folding plate 24.

[0043] The fixed plate 23 is fixedly connected to the top of the extension plate 21, so that when the extension plate 21 is unfolded, the fixed plate 23 moves together with the extension plate 21. To facilitate use by the driver or front passenger, the fixed plate 23 and the extension plate 21 are connected by a rotatable bracket, which includes a first rotating seat 210 and a second rotating seat 230. Specifically, the first rotating seat 210 is fixedly connected to the top of the extension plate 21, and the second rotating seat 230 is fixedly connected to the bottom of the fixed plate 23. The first rotating seat 210 and the second rotating seat 230 are rotatably connected. The first rotating seat 210 is fastened to the extension plate 21 by screws or bolts, and the first rotating seat 210 and the second rotating seat 230 are coaxially connected. A limit structure is provided between them to restrict the rotation angle of the fixed plate 23, allowing the fixed plate 23 to rotate at most 180°. The fixed plate 23 is fastened to the second rotating seat 230 by screws or bolts.

[0044] The fixed plate 23 and the folding plate 24 are connected by a hinge, which can be either a shaft hole type or a louvered type. In this embodiment, the type of hinge is not limited, and a reasonable choice can be made according to the actual situation.

[0045] Based on the above embodiments, in this embodiment, the folding table also includes a support arm 3, one end of which is rotatably connected to the lifting base 1, and the other end is hinged to the extension plate 21.

[0046] The support arm 3 includes a first arm 30 and a second arm 31. The first arm 30 is rotatably connected to the lifting base 1. The second arm 31 is slidably connected to the first arm 30 along its length extension direction, and one end is hinged to the extension plate 21. Specifically, the first arm 30 is rotatably connected to the upper bracket 13 in the lifting base 1, so that the support arm 3 can move with the movement of the upper bracket 13. When the extension plate 21 slides relative to the support plate 20, the first arm 30 rotates relative to the upper bracket 13, and the second arm 31 slides along the length extension direction of the first arm 30 under the pull of the extension rod, so that the length of the support arm 3 extends. When the table structure 2 is unfolded for use, the second arm 31 provides support for the table structure 2; when the table structure 2 is retracted, the second arm 31 rotates along the pivot on the extension plate 21 and retracts along the first arm 30.

[0047] Therefore, the folding table in this application is fixed to the vehicle body sheet metal by the mounting base 10, and can be hidden inside the passenger dashboard when not in use. Taking the use of the front passenger as an example, the process of using the folding table is as follows: First, the lifting screw 12 driven by the motor raises the folded table structure 2 to a height suitable for the use of the driver and passengers. Then, the extension plate 21, together with the folded fixed plate 23 and the folding plate 24, is manually slid along the support plate 20 to the use side (which can be the driver's side or the passenger's side) via the connecting hinge 22. After the extension plate 21 is interactively opened to a horizontal state with the support plate 20 (see...), Figure 3 Tabletop structure 2 is in its second state (tabletop structure 2 is opened halfway). Then, the folding plate 24 is flipped open from the fixed plate 23 and flush with the fixed plate 23, thus forming a small tabletop that passengers can place for eating boxed meals or for placing laptops for work (see...). Figure 4 Tabletop structure 2 is in the third state, with tabletop structure 2 fully opened.

[0048] If the driver is using the device, the operating procedure is the same as that for the front passenger, except that before the folding panel 24 folds open the table structure 2, the fixing plate 23 needs to be rotated 180° so that the folding panel 24 unfolds along the driver's left side (e.g., Figure 5 As shown, the tabletop structure 2 is in the third state, with the tabletop structure 2 fully opened and located to the left of the lifting base 1.

[0049] In summary, the folding table in this application can be placed at the front and rear of the passenger dashboard and can be hidden; the table structure 2 can be unfolded to the left and right, providing space for the driver or passenger to rest and work respectively; the folding table can be raised, lowered, and folded away, offering the following advantages over other small table structures 2 within the same layout space:

[0050] Using one set of lifting base 1 and table structure 2 can meet the needs of the driver or passenger for rest and work respectively. There is no need to set up two sets of table structure 2 and lifting base 1. Compared with the existing technology, it reduces one set of table structure 2 and lifting base 1, making assembly simpler and more cost-effective.

[0051] The table structure 2 allows it to be more centrally positioned relative to the seating position of the driver and passengers, making it more comfortable and convenient to use;

[0052] The tabletop structure 2 offers a larger usable area, making it more comfortable to use.

[0053] Secondly, embodiments of this application provide a vehicle that includes the folding table provided in any of the above embodiments of this application.

[0054] In this application, the folding table can be folded up and stowed away. Under the same layout space, the width of the folding table can be designed according to the maximum width of the sub-dashboard. The table structure 2 has three states. The table structure 2 can be extended along the width direction of the vehicle body so that the table structure 2 reaches the middle position between the driver and the front passenger, making it more convenient and comfortable to use.

[0055] The folding table in this application is fixed to the vehicle body sheet metal via the mounting base 10. When not in use, it can be hidden inside the passenger dashboard. Taking the use of the front passenger as an example, the process of using the folding table is as follows: First, the lifting screw 12 driven by the motor raises the folded table structure 2 to a height suitable for the use of the passenger. Then, the extension plate 21, along with the folded fixed plate 23 and the folding plate 24, is manually slid along the support plate 20 to the use side (either the driver's side or the passenger's side) via the connecting hinge 22. After the extension plate 21 is interactively opened to a horizontal position with the support plate 20 (see...), Figure 3 Tabletop structure 2 is in its second state (tabletop structure 2 is opened halfway). Then, the folding plate 24 is flipped open from the fixed plate 23 and flush with the fixed plate 23, thus forming a small tabletop that passengers can place for eating boxed meals or for placing laptops for work (see...). Figure 4 Tabletop structure 2 is in the third state, with tabletop structure 2 fully opened.

[0056] If the driver is using the device, the operating procedure is the same as that for the front passenger, except that before the folding panel 24 folds open the table structure 2, the fixing plate 23 needs to be rotated 180° so that the folding panel 24 unfolds along the driver's left side (e.g., Figure 5 As shown, the tabletop structure 2 is in the third state, with the tabletop structure 2 fully opened and located to the left of the lifting base 1.

[0057] In summary, the folding table in this application can be placed at the front and rear of the passenger dashboard and can be hidden; the table structure 2 can be unfolded to the left and right, providing space for the driver or passenger to rest and work respectively; the folding table can be raised, lowered, and folded away, offering the following advantages over other small table structures 2 within the same layout space:

[0058] Using one set of lifting base 1 and table structure 2 can meet the needs of the driver or passenger for rest and work respectively. There is no need to set up two sets of table structure 2 and lifting base 1. Compared with the existing technology, it reduces one set of table structure 2 and lifting base 1, making assembly simpler and more cost-effective.

[0059] The table structure 2 allows it to be more centrally positioned relative to the seating position of the driver and passengers, making it more comfortable and convenient to use;

[0060] The tabletop structure 2 offers a larger usable area, making it more comfortable to use.
