[0019] For example, the automatic reset omnidirectional rotating platform of the present invention can be applied to the field of robotics where passive and automatic reset is required.

[0020] like Figure 1 As shown, an embodiment of the present invention provides an automatic reset omnidirectional rotating platform, wherein the platform includes an upper base 1, a lower base 2, a hinge mechanism 3, a connecting rod mechanism 4 and an elastic unit 5, wherein two ends of the elastic unit 5 are respectively fixedly connected to the lower surface of the upper base 1 and the upper surface of the lower base 2 to provide automatic reset, the hinge mechanism 3 is arranged on the lower surface of the upper base 1 and the upper surface of the lower base 2 to provide two degrees of freedom in two directions, the connecting rod mechanism 4 is connected to the hinge mechanism 3 (that is, the two ends of the connecting rod mechanism are respectively connected to the hinge mechanism arranged on the upper base and the hinge mechanism on the lower base), and the connecting rod mechanism 4 is a curved structure to avoid interference during movement.

[0021] Through the above technical solution, the platform can be reset by the strength of the elastic unit, and the connecting rod mechanism is connected to the hinge structure, which can move with two degrees of freedom, so that the platform can move 360° spherical surface and realize rotation. In addition, the automatic reset omnidirectional rotating platform of the present invention has the advantages of small size and light weight.

[0022] According to an embodiment of the present invention, the connecting rod mechanism 4 is a uu connecting rod mechanism.

[0023] According to an embodiment of the present invention, the connecting rod mechanism 4 is S-shaped in the radial direction of the platform.

[0024] This can avoid interference during the activity.

[0025] According to an embodiment of the present invention, the number of the connecting rod mechanisms 4 is three, and the three connecting rod mechanisms 4 form a 3-uu parallel mechanism to provide spherical-like movement for the platform.

[0026] Passive reset capability is provided through the 3-UU parallel mechanism and spring, while meeting the technical adaptability requirements of platform rotation and automatic reset.

[0027] According to an embodiment of the present invention, the elastic unit 5 is a spring.

[0028] The spring is used as an elastic unit to provide a certain rigidity, and the platform is reset by the strength of the spring.

[0029] like Figure 2As shown, the number of hinge structures can be six, and the six hinge structures include a first hinge structure 2-1, a second hinge structure 2-2, a third hinge structure 2-3, a fourth hinge structure 2-4, a fifth hinge structure 2-5 and a sixth hinge structure 2-6; the number of connecting rod mechanisms 4 is three, and the three connecting rod mechanisms 4 include a first connecting rod structure 2-7, a second connecting rod structure 2-8 and a third connecting rod structure 2-9.

[0030] Among them, the first hinge structure 2-1, the second hinge structure 2-2, and the third hinge structure 2-3 are arranged on the lower surface of the upper base 1, and the fourth hinge structure 2-4, the fifth hinge structure 2-5 and the sixth hinge structure 2-6 are arranged on the upper surface of the lower base 2; the upper ends of the first connecting rod structure 2-7, the second connecting rod structure 2-8 and the third connecting rod structure 2-9 are respectively connected to the second hinge structure 2-2, the third hinge structure 2-3 and the first hinge structure 2-1, and the lower ends of the first connecting rod structure 2-7, the second connecting rod structure 2-8 and the third connecting rod structure 2-9 are respectively connected to the fifth hinge structure 2-5, the sixth hinge structure 2-6 and the fourth hinge structure 2-4.

[0031] The rotation process of the automatic reset omnidirectional rotating platform of the present invention is as follows: Figure 3 shown.

[0032] like Figure 4 As shown, the automatic reset omnidirectional rotating platform of the present invention can be installed on a movable platform, the lower base is fixedly connected to the upper surface of the movable platform, and the upper base is connected to a rod. During the implementation process, the rod connected to the upper base can rotate at different angles according to the change of environmental conditions; after completing the operation, it can return to the initial position and angle through the passive reset ability provided by the spring.

[0033] It can be seen from the above embodiments that the automatic reset omnidirectional rotating platform of the present invention has at least the following advantages compared with the prior art: small size and light weight. In addition, the 3-uu parallel mechanism can provide 360° rotation activities; the spring can provide automatic reset capability, and the environmental adaptability of the platform can be improved by adjusting the spring elastic coefficient.

[0034] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0035] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0036] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
