The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1 and 2, fig. 1 schematically illustrates a foldable support provided by an embodiment of the present invention in a folded state; fig. 2 schematically illustrates a structure of a desktop stand provided by an embodiment of the present invention in a use state, in which a foldable stand is in an unfolded state.

As can be seen, the foldable stand of the present embodiment includes a foldable support arm and base 100.

The folding support arm comprises a first rod 300, a second rod 400 and a third rod 500 which are sequentially connected in a rotating manner through a damping connection structure 200, one end of the first rod 300 is movably connected with the base 100, and one end of the third rod 500 is used for connecting a clamping piece 600. Wherein a first rotation axis of the first lever 300 to rotate with respect to the second lever 400 is parallel to a second rotation axis of the third lever 500 to rotate with respect to the second lever 400, and projections of the first lever 300, the second lever 400, and the third lever 500 do not overlap each other on a plane on which the first rotation axis and the second rotation axis are located, so that the first lever 300, the second lever 400, and the third lever 500 can be folded to be coplanar.

The base 100 is provided with a mounting seat 110 and a receiving position 120, the mounting seat 110 is movably connected with one end of the first rod 300, and the receiving position 120 is used for receiving the first rod 300, the second rod 400 and the third rod 500 in a folded state, that is, the folding support arm is folded and received in the receiving position 120.

In the foldable bracket of this embodiment, the first rod 300, the second rod 400, and the third rod 500 are sequentially rotatably connected by the damping connection structure 200, so that the first rod 300, the second rod 400, and the third rod 500 relatively rotate with respect to each other, so that the foldable bracket can be adjusted in multiple degrees of freedom and in a wide angle range, for example, in up-down, front-back, and other directions; the damping connection structure 200 has a damping effect on two rods connected with the damping connection structure, so that the rods are not easy to shake, the stability of the support in use is improved, and the support is convenient to fix at a specific angle. The user can adjust the angle only by rotating the first rod 300, the second rod 400 and the third rod 500, and the angle adjustment is simple and convenient compared with the conventional support using the flexible support arm.

In addition, because the first rod 300, the second rod 400 and the third rod 500 are foldable and coplanar, that is, the first rod 300, the second rod 400 and the third rod 500 after being folded can be positioned on the same plane, the space volume occupied after the folding of the folding support arm is reduced, the structural size of the storage position 120 on the base 100 can be smaller, so that the structure of the folding support arm is more compact and smaller when being folded, and the carrying is convenient.

For the above-mentioned receiving positions 120, the receiving positions 120 are receiving platforms or receiving slots provided on the base 100, that is, the receiving positions 120 may be receiving platforms formed by extending the base 100, and the folding supporting arms are received and placed on the receiving platforms; or a recess formed by recessing the upper surface of the base 100 toward the lower surface, a receiving space is formed inside the recess, and the folding support arm is received in the receiving space.

Preferably, the receiving position 120 is a receiving platform formed by extending the base 100. This approach is beneficial to reducing the structural size of the base 100, while reducing the cost of the base 100 for the production materials.

In some embodiments, the mount 110 may be disposed at an end of the receiving location 120. At this time, the accommodating position 120 itself may form a counterweight portion of the base, which is beneficial to improving the structural stability of the foldable support, so that the foldable support can be stably placed on supporting surfaces such as a desktop.

With continued reference to fig. 1 and 2, in the embodiment shown, the third rod 500 is positioned between the first rod 300 and the second rod 400 when the first rod 300, the second rod 400, and the third rod 500 are folded to be coplanar. In this way, when the first rod 300, the second rod 400 and the third rod 500 are folded, the structure similar to a clip can be formed to be folded and stored in the storage position 120 of the base 100, and the storage is convenient.

Wherein the second pole 400 is located at the inner arc side of the first pole 300 and the third pole 500, and the first pole 300 and the third pole 500 are located at the inner arc side of the second pole 400, so that the third pole 500, the second pole 400 and the first pole 300 form a spiral line structure gradually spreading outward from the inside to the outside when the first pole 300, the second pole 400 and the third pole 500 are in the folded state.

With continued reference to fig. 1 and 2, in the illustrated embodiment, the second rod 400 includes a second rod upper segment 400a and a second rod lower segment 400b rotationally coupled by the damping coupling structure 200, and a third rotational axis about which the second rod upper segment 400a rotates relative to the second rod lower segment 400b is coplanar with and perpendicular to the first and second rotational axes. Wherein the second upper rod segment 400a and the second lower rod segment 400b may both be L-shaped or arc-shaped.

In this embodiment, the third axis of rotation is coplanar with and perpendicular to the first and second axes of rotation, respectively, such that the first rod 300, the second rod 400, the third rod 500, and the second rod upper segment 400a and the second rod lower segment 400b are in rotational engagement with each other. So for foldable support increases a rotational degree of freedom, can realize 360 degrees angular adjustment in space, improve foldable support's flexibility greatly, can satisfy the use scene of the daily support angular adjustment of most users, for example assist live broadcast, watch video etc..

It should be noted that in other embodiments, the third rotation axis may not be perpendicular to the first rotation axis and the second rotation axis, for example, the third rotation axis intersects with the first rotation axis and the second rotation axis but is not perpendicular to the first rotation axis and the second rotation axis.

The number of the spring clips may be one or multiple, and when the number of the spring clips is multiple, the spring clips may be sequentially arranged along the axial direction of the shaft column 221.
