Detailed Implementation

[0032] The present invention will now be described in conjunction with specific embodiments.

[0033] Example 1, as Figures 1 to 4 As shown, a multi-link door opening and closing structure includes a support body 1, a drive motor 2, a left door body 31, and a right door body 32. The drive motor 2 is fixedly installed on the support body 1, and the left door body 31 and the right door body 32 are arranged facing each other from left to right.

[0034] Among them, such as Figures 1 to 3 As shown, the left door 31 is equipped with a left connecting rod assembly 41, and the right door 32 is equipped with a right connecting rod assembly 42.

[0035] Furthermore, such as Figures 1 to 3 As shown, the power output shaft of the drive motor 2 is equipped with a torque regulator 5, the torque regulator 5 is equipped with a drive component 6, and the drive component 6 is provided with a left drive rod 61 and a right drive rod 62 that rotate synchronously. The left drive rod 61 drives the left door body 31 to move through the left connecting rod assembly 41, and the right drive rod 62 drives the right door body 32 to move through the right connecting rod assembly 42.

[0036] In the process of opening and closing the left door 31 and right door 32 of the double-leaf door structure in the multi-link door opening and closing structure of this embodiment, the drive motor 2 drives the drive component 6 to rotate through the torque regulator 5, and the left drive rod 61 and right drive rod 62 rotate synchronously. During this process, the left drive rod 61 drives the left door 31 to open and close through the left link assembly 41, and the right drive link drives the right door 32 to open and close through the right link assembly 42, thereby enabling the left door 31 and right door 32 of the double-leaf door structure to open and close.

[0037] It should be emphasized that the multi-link door opening and closing structure of this embodiment 1 uses a drive motor 2 to drive the left door body 31 and the right door body 32 to move synchronously. Compared with the prior art, the overall structure of the multi-link door opening and closing structure of this embodiment 1 is simpler.

[0038] Furthermore, regarding the torque adjuster 5 in this embodiment, the user can adaptively adjust the torque of the torque adjuster 5. When the left door 31 and the right door 32 are closed, that is, when the left door 31 and the right door 32 are rotated to the closed position respectively, the left door 31 blocks and reacts to the right door 32, and the right door 32 blocks and reacts to the left door 31. At this time, the torque adjuster 5 is subjected to an external force. When the external force is greater than the torque value set by the torque adjuster 5, slippage occurs between the power output shaft of the drive motor 2 and the torque adjuster 5. Therefore, the multi-link door opening and closing structure in this embodiment can set the closing clamping force through the torque adjuster 5, thereby achieving the anti-pinch function and high safety.

[0039] In summary, the multi-link door structure of this embodiment has the advantages of novel design, simple structure, and high safety, and only requires one motor to realize the opening and closing action of the double door structure.

[0040] Example 2, as Figures 1 to 3 As shown, the difference between this embodiment 2 and embodiment 1 is that: the left connecting rod assembly 41 includes a left first connecting rod 411 and a left second connecting rod 412. The left second connecting rod 412 is pivotally hinged to the bracket body 1, and the left second connecting rod 412 is provided with two free ends; one end of the left first connecting rod 411 is pivotally connected to the end of the left drive rod 61, the other end of the left first connecting rod 411 is pivotally connected to one of the free ends of the left second connecting rod 412, and the other free end of the left second connecting rod 412 is pivotally connected to the left door body 31.

[0041] Similarly, the right-side linkage assembly 42 includes a right-side first linkage 421 and a right-side second linkage 422. The right-side second linkage 422 is pivotally hinged to the bracket body 1 and has two free ends. One end of the right-side first linkage 421 is pivotally connected to the end of the right-side drive rod 62, and the other end of the right-side first linkage 421 is pivotally connected to one of the free ends of the right-side second linkage 422. The other free end of the right-side second linkage 422 is pivotally connected to the right-side door body 32.

[0042] Example 3, as Figure 1 As shown, the difference between this embodiment 3 and embodiment 2 is that: the end of the left door body 31 away from the left second connecting rod 412 is equipped with a left third connecting rod 413, one end of the left third connecting rod 413 is pivotally connected to the left door body 31, and the other end of the left third connecting rod 413 is pivotally connected to the bracket body 1.

[0043] Similarly, a right third link 423 is installed at the end of the right door 32 that is away from the right second link 422. One end of the right third link 423 is pivotally connected to the right door 32, and the other end of the right third link 423 is pivotally connected to the support body 1.

[0044] Example 4, as Figure 1 As shown, the difference between this embodiment four and embodiment two is that the bracket body 1 is equipped with a closed position switch 71 and an open position switch.

[0045] The multi-link door structure of this embodiment four is applied to an intelligent robot, and the closed position switch 71 and the open position switch of this embodiment four are electrically connected to the controller of the intelligent robot, and the drive motor 2 of this embodiment four is also electrically connected to the controller of the intelligent robot.

[0046] During operation, when the left door 31 or the right door 32 rotates to the closed position, the left second link 412 or the right second link 422 triggers the closed position switch 71. The closed position switch 71 sends a feedback signal to the controller of the intelligent robot, which then controls the drive motor 2 to stop moving, so that the drive motor 2 stops moving when the left door 31 and the right door 32 are closed.

[0047] When the left door 31 or the right door 32 rotates to the open position, the left second link 412 or the right second link 422 triggers the open position switch. The open position switch sends a feedback signal to the controller of the intelligent robot, which then controls the drive motor 2 to stop moving, so that the drive motor 2 stops moving when the left door 31 or the right door 32 is fully opened.

[0048] Example 5: An intelligent robot that includes the above-described multi-link door opening and closing structure.

[0049] It should be noted that, since the above-mentioned multi-link door opening and closing structure has the advantages of novel design, simple structure and high safety, the intelligent robot in this embodiment five also has the advantages of novel design, simple structure and high safety.

[0050] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
