[0049] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0050] Example 1: An elastic support base frame, as shown in Figures 1, 2, 3, 4, 5, and 6, includes a support base frame 1, a table body 2, and an elastic body 3. The table body is rotatably connected to the support base frame. This rotatable connection can be a direct rotatable connection, as shown in Figure 8, or a linkage rotatable connection achieved through a linkage structure, such as the linkage rotatable connections described in applications 202122397916.3 and 201721852454.7. The first elastic end of the elastic body contacts or is connected to the table body, and the second elastic end of the elastic body contacts or is connected to the support base frame. During the process of the table body rotating from a horizontal position to a stowed position, the elastic body is subjected to compression or tension. A first connecting platform 13 and the first elastic end of the elastic body are provided on the support base frame. The table body is provided with a second connecting platform 22 that contacts or connects to the second elastic end of the elastic body. A base frame 11 and a support frame 12 are provided on the supporting chassis frame. The table body is rotatably connected to the support frame, and the second elastic end of the elastic body contacts or connects to the support frame. There is at least one support frame. There is at least one elastic body.

[0051] In this embodiment, the elastic body is a tension spring, and there are four in total: two first tension springs 34 and two second tension springs 35. The table is stored in a vertical position when the tabletop is rotated. The folding table is stored in a vertical or near-vertical position when the tabletop rotates from a horizontal to a vertical position. When the tabletop rotates from a horizontal to a vertical position, the first tension spring 34 is under tension and in an energy-storing state. When the tabletop rotates from a vertical to a horizontal position, the second tension spring 35 is under tension and in an energy-storing state. When the tabletop rotates from a vertical to a horizontal position, the first tension spring releases its stored energy to help the user rotate the tabletop from a vertical to a horizontal position. When the tabletop rotates from a horizontal to a vertical position, the second tension spring releases its stored energy to help the user rotate the tabletop from a horizontal to a vertical position. This saves the user the force applied to the tabletop and assists the user in storing and unfolding the folding table, making it easy for the user to store and unfold the table.

[0052] As shown in Figures 1, 3, and 6, the first connecting platform 13 is a shaft component that is fixedly connected to the supporting chassis frame, and one end of the first tension spring 34 is hung on the first connecting platform 13.

[0053] As shown in Figures 4 and 5, the first connecting platform 13 is a right-angled plate. The vertical side of the right-angled plate is welded to the support frame, and the horizontal side of the right-angled plate has a connecting hole. One end of the second tension spring 35 is hung in the connecting hole.

[0054] The second connecting platform 22 is a shaft component. A second connecting platform 22 is provided at each end of the connecting plate. The second connecting platform 22 is fixedly connected to the connecting plate. The second connecting platform near the first tension spring 34 is connected to the other end of the first tension spring 34, and the second connecting platform 22 near the second tension spring 35 is connected to the other end of the second tension spring 35.

[0055] In this embodiment, the chassis frame includes a base plate, columns, and crossbeams, which are connected in sequence. There are two support frames, which are respectively set on both sides of the crossbeams. The support frames and the crossbeams form a U-shaped fork.

[0056] A connecting plate 21 is provided on the table body. The connecting plate is rotatably connected to the supporting chassis frame. The connecting plate is either fixedly connected to the table body or detachably connected. The first elastic end of the elastic body is in contact with or connected to the connecting plate.

[0057] Example 2: The scheme is basically the same as that in Example 1, except that the elastic body in this example is a torsion spring, as shown in Figures 7, 8, 9 and 10: The connecting plate is rotatably connected to the support frame via the connecting shaft 4, and a torsion spring is sleeved on the connecting shaft 4. As shown in Figure 7, the first arm 31 and the second arm 32 of the torsion spring 3 are disposed between the first connecting platform 13 and the connecting plate. The first arm contacts the bottom of the connecting plate, and the second arm contacts the side of the first connecting platform near the connecting plate.

[0058] As shown in Figure 8, the first arm 31 and the second arm 32 of the torsion spring 3 are disposed between the first connecting platform 13 and the connecting plate. The first arm contacts the top of the connecting plate, and the second arm contacts the side of the first connecting platform away from the connecting plate.

[0059] When the tabletop rotates from a horizontal to a vertical position, one torsion spring is under pressure and in a stored energy state. When the tabletop rotates from a vertical to a horizontal position, the other torsion spring is under pressure and in a stored energy state. When the tabletop rotates from a vertical to a horizontal position, one torsion spring releases its stored energy to help the user rotate the tabletop from a vertical to a horizontal position. When the tabletop rotates from a horizontal to a vertical position, the other torsion spring releases its stored energy to help the user rotate the tabletop from a horizontal to a vertical position. This saves the force that the user applies to the tabletop and assists the user in storing and unfolding the folding table, making it easy for the user to store and unfold the folding table.

[0060] Example 3 adopts a scheme that is basically the same as that of Example 1, as shown in Figures 11, 12, 13, and 14. Figure 15As shown in Figures 16, 17, 18, and 19, the difference lies in that the table in this embodiment is connected to the supporting chassis frame via a linkage assembly, forming a flip-able connection. This flip-able connection means that the table is connected to the supporting chassis frame via the linkage assembly, allowing the table to have both a stowed and a usable state. Furthermore, the table can switch between these states according to the trajectory constrained by the linkage assembly. There are many types of linkage assemblies available on the market, and they are combinations of various linkages to achieve a set goal. In this embodiment, the linkage assembly is a hinged screw structure, including a first linkage 7 and a second linkage 8. The first end of the first linkage 7 is hinged to the supporting chassis frame, and the second end of the first linkage 7 is hinged to the table body; the first end of the second linkage 8 is hinged to the supporting chassis frame, and the second end of the second linkage 8 is hinged to the table body. A first elastic body is provided between any two of the table body, the supporting chassis frame, the first connecting rod 7, and the second connecting rod 8. The first elastic end of the first elastic body is in contact or connected to one of the table body, the supporting chassis frame, the first connecting rod 7, and the second connecting rod 8, and the second elastic end of the first elastic body is in contact or connected to the other of the table body, the supporting chassis frame, the first connecting rod 7, and the second connecting rod 8. As long as the first elastic body is provided between any two of the table body, the supporting chassis frame, the first connecting rod 7, and the second connecting rod 8, there will be relative movement between the table body, the supporting chassis frame, the first connecting rod 7, and the second connecting rod 8. This allows the first elastic body to be compressed or stretched, so that when the table body is in a turned storage state or a turned use state, the first elastic body can accumulate elastic potential energy. According to the principle of conservation of energy and the kinetic energy theorem, by accumulating the kinetic energy of the table body through the first elastic body, the rotation speed of the table body can be reduced, the inertial force of the table body can be reduced, and the table body can be prevented from tipping over due to inertia. Furthermore, when the table transitions from a folded state to a usable state, or vice versa, the accumulated elastic potential energy is released, assisting the user in more easily switching between these states. For users with less strength, such as women, the elderly, and teenagers, flipping the table often presents challenges. Due to the table's weight, it may be difficult to lift when transitioning from a usable state to a vertically folded state, or vice versa. Alternatively, when transitioning from a usable state to a vertically folded state, the table's inertia may cause it to tip over the supporting frame, damaging both the table and the frame, potentially leading to injury. In this embodiment, the folded state refers to the table being vertical, while the usable state refers to the table being horizontally positioned with the supporting frame vertically positioned.

[0061] A second elastic body is provided between any two of the table body, the supporting chassis frame, the first connecting rod 7, and the second connecting rod 8. The first elastic end of the second elastic body is in contact with or connected to one of the table body, the supporting chassis frame, the first connecting rod 7, and the second connecting rod 8, and the second elastic end of the second elastic body is in contact with or connected to the other of the table body, the supporting chassis frame, the first connecting rod 7, and the second connecting rod 8. By incorporating a second elastic body between any two of the table body, supporting base frame, first link 7, and second link 8, relative movement will occur between these components. This allows the second elastic body to be compressed or stretched, accumulating elastic potential energy. This further distributes the kinetic energy of the table body, reducing its rotational speed and inertia, preventing it from tipping over. Furthermore, it makes it easier to flip the table when transitioning from its active state to a vertically folded state, thus facilitating its use.

[0062] During the process of rotating the table from the use state to the storage state, the first elastic body can be compressed or stretched.

[0063] During the process of rotating the table from the storage state to the use state, the first elastic body can be compressed or stretched.

The second end of the first base rod 71 is connected to the fixed end of the first stop 72. The supporting end of the first stop 72 is located away from the first base rod 71 and is connected to the first end of the first inner rod 73.
