Example 1

The embodiment of the application discloses a structure for realizing multi-mutual-exclusion motion through single drive.

As shown in fig. 1, a structure for realizing multiple mutually exclusive motions by a single drive includes a second mechanism M1, a sliding slot M11 disposed on the second mechanism M1, a sliding hinge connection structure H disposed in the sliding slot M11, a switching device K disposed on the second mechanism M1, a connecting rod L fixed on the sliding hinge connection structure H, a third mechanism M2 fixed at the left end of the connecting rod L, a drive structure P fixed at the right end of the connecting rod L, and a first mechanism M0 fixed together with the drive structure P.

The second mechanism M1 is provided with a pin hole for fixing the switching device K, and the switching device K can rotate along the pin hole; and the switching device K is matched with the sliding hinge connecting structure H.

When the switching device is lifted up, the sliding hinge connecting structure can freely slide in the sliding groove, and when the switching structure is put down, the sliding hinge connecting structure can be limited at the right end of the sliding groove, so that the sliding hinge connecting structure can not slide in the sliding groove.

The first mechanism M0 is provided with a mode switching mechanism for controlling the first mechanism M0 to be fixed or movable.

The second mechanism M1 is also provided with a mode switching mechanism for controlling the second mechanism M1 to be fixed or movable.

The mode conversion structure has multiple realization modes, such as a clamp, a bolt, a fixed rod, a fixed rope and the like, and the specific fixing mode can be flexibly set according to the actual use requirement. In the present application, the purpose of setting the mode switching structure is only to switch the fixed/movable state of the first mechanism and/or the second mechanism, and a person skilled in the art may set a specific structure according to his/her needs, without creative work, and will not be described herein again.

The specific motion realization process is as follows:

as shown in fig. 2, when the first mechanism and the second mechanism are both fixed by the mode conversion structure and the switching device is lifted to be separated from the sliding hinge connection structure, the driving structure stretches and retracts to drive the connecting rod connected with the driving structure to move left and right, and the connecting rod drives the third mechanism to move all together.

As shown in fig. 3, when the first mechanism is fixed through the mode conversion structure, the second mechanism is movable through the mode conversion structure, and the switching device is put down to limit the sliding hinge connection structure, the driving structure stretches out and draws back to drive the connecting rod to move left and right, and the sliding hinge connection structure cannot slide in the sliding groove under the limit of the switching device, so that the second mechanism can reciprocate left and right along with the connecting rod, and meanwhile, the third mechanism can be driven to reciprocate left and right due to the left and right movement of the connecting rod.

As shown in fig. 4, when the second mechanism is fixed through the mode switching structure, the first mechanism moves through the mode switching structure, and the switching device is put down to limit the sliding hinge connection structure, the driving structure stretches and retracts and cannot drive the connecting rod to move, so that the driving structure and the first mechanism fixed together with the driving structure perform left-right reciprocating motion under the action of a reaction force.

According to the description, the structure of the application can carry out three different and mutually exclusive motions through one driving structure, the complexity of the structure is greatly reduced, meanwhile, the utilization rate of the driving structure is effectively improved, and the requirements of the current society are better met.

In addition, the above-described embodiments are exemplary, and those skilled in the art, having benefit of this disclosure, will appreciate numerous solutions that are within the scope of the disclosure and that fall within the scope of the utility model. It should be understood by those skilled in the art that the present specification and figures are illustrative only and are not limiting upon the claims.
