Embodiment 1

[0036] The bidirectional driving device provided by this embodiment, such as Figure 1 to Figure 8 As shown, it includes a bidirectional driver 4, a wire slot 1 (single-layer wire slot or multi-layer wire slot is acceptable) and a ratchet assembly. The ratchet assembly is divided into a positive ratchet assembly and a reverse ratchet assembly with opposite stop directions; The components are respectively socketed and fixed with the output shafts of the two-way drive 4; there are two wire slots 1, which are respectively connected to the positive ratchet assembly and the reverse ratchet assembly; the two-way drive 4 rotates forward, and the corresponding wire slot 1 is driven to rotate through the positive ratchet assembly. The slot 1 corresponding to the anti-ratchet assembly does not rotate; the two-way driver 4 rotates in reverse, and the corresponding slot 1 is driven to rotate by the anti-ratchet assembly, and the slot 1 corresponding to the positive ratchet assembly does no...

Abstract

The invention relates to a bidirectional drive device and belongs to the technical field of drive mechanisms. The problem that in the prior art, a bidirectional drive device cannot drive two components to move independently in a time-share manner is solved. The bidirectional drive device comprises a bidirectional driver, trunkings and ratchet wheel assemblies. The ratchet wheel assemblies are divided into a positive ratchet wheel assembly and a negative ratchet wheel assembly, wherein the stop directions of the positive ratchet wheel assembly and the negative ratchet wheel assembly are contrary. The positive ratchet wheel assembly and the negative ratchet wheel assembly are fixed to an output shaft of the bidirectional driver correspondingly in a cup joint manner. The two trunkings are connected with the positive ratchet wheel assembly and the negative ratchet wheel assembly correspondingly. When the bidirectional driver rotates positively, the corresponding trunking is driven to rotate through the positive ratchet wheel assembly. When the bidirectional driver rotates negatively, the corresponding trunking is driven to rotate through the negative ratchet wheel assembly. The bidirectional drive device provided by the invention can be used for driving two ropes to move independently in a time-share manner.

Description

technical field [0001] The invention relates to a driving mechanism, in particular to a bidirectional driving device based on double ratchets. Background technique [0002] The rope is a typical rope, and the driving device transmits motion and power to the target through the rope. Due to the flexible installation between the rope and the driving device and the low weight of the moving part (rope), the response speed of the rope-driving device is very fast. [0003] In the prior art, the above-mentioned driving device is usually a two-way drive, and the two-way drivers correspond to the ropes one by one, that is, one two-way driver drives one rope. [0004] However, since the bidirectional driver can perform both forward and reverse motions, the rope-drive device can only use the forward or reverse rotation of the bidirectional driver, and cannot effectively utilize the bidirectional rotation of the bidirectional driver, resulting in waste of resources. Especially for some ...
