The assembly relationship of an embodiment of the opening and closing mechanism of the trash can according to the present invention is described below with reference to fig. 3 to 5: the first shaft seat 111 of the connecting seat 11 is correspondingly inserted into the second shaft seat 211 of the cover body 2 and the through hole on the first shaft seat 111 is relatively communicated with the through hole on the second shaft seat 211; after one end of the support shaft 4 passes through one side ends of the first shaft seat 111 and the second shaft seat 211, the torsion spring 6 and the sleeve 5 are sequentially sleeved on the support shaft 4, and then the support shaft 4 continuously passes through the other side ends of the first shaft seat 111 and the second shaft seat 211; two ends of the supporting shaft 4 are sleeved in the wiring corner connectors 7, and the wiring corner connectors 7, the sleeve 5 and the torsion spring fixing block 65 are fixed on the supporting shaft 4 and the wiring corner connectors 7 are fixed on the cover body 2 by screws; the motor 31 is fixed on the connecting seat 11, the connecting rod assembly 3 is connected between the motor 31 and the sleeve 5, one end of the linear damper 8 is fixed on the connecting seat 11, and the other end of the linear damper is connected on the sleeve 5.
The working process of the garbage can cover opening and closing mechanism provided by the utility model is as follows: when the cover is opened, the motor 31 is started, the output end 311 of the motor 31 rotates to drive the connecting rod assembly 3 to move, the connecting rod assembly 3 drives the supporting shaft 4 to rotate through the sleeve 5, the supporting shaft 4 rotates to drive the cover body 2 to rotate and open, meanwhile, the torsion spring 6 also provides a force for driving the cover body 2 to rotate and open due to elastic deformation and compression, and the telescopic rod 81 of the linear damper 8 is driven by the rotation of the sleeve 5 to be stretched; when the cover is closed, the motor 31 is started, the output end 311 of the motor 31 rotates reversely to drive the connecting rod assembly 3 to move reversely, the connecting rod assembly 3 drives the supporting shaft 4 to rotate reversely through the sleeve 5, the supporting shaft 4 rotates to drive the cover body 2 to rotate and close, meanwhile, the torsion spring 6 is compressed and deformed, and the telescopic rod 81 of the linear damper 8 is compressed by the reverse rotation of the sleeve 5 to provide damping force and realize the slow closing of the cover body 2.
Referring to fig. 1 and fig. 2 again, the intelligent trash can provided by the utility model comprises a can body 1 and the trash can opening and closing mechanism, wherein the intelligent trash can comprises a large cover 21 covering the can body 1 and a small cover 22 covering the large cover 21. In an embodiment, the lid 2 included in the opening and closing mechanism of the trash can may be a large lid 21, and the connecting seat 11 is a part of the can body 1; in another embodiment, the cover body 2 included in the opening and closing mechanism of the trash can may be a small cover 22, and the connecting seat 11 is a part of the large cover 21.
As can be seen from the above detailed description of the embodiment, the cover opening and closing mechanism of the trash can provided by the utility model is provided with the support shaft 4 fixedly connected to the cover body 2 and used for hinging the cover body 2 with the connecting seat 11, the motor 31 drives the support shaft 4 to rotate through the connecting rod assembly 3 to drive the cover body 2 to rotate to open and close, the support shaft 4 has better rigidity and has a larger contact area with the cover body 2, a better force transmission effect can be realized, the force for driving the cover body 2 to open and close is more balanced, the cover opening and closing is more stable, and the support shaft 4 is driven by the connecting rod assembly 3 to rotate to provide a larger moment.
Although the present application has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the application, and all changes, substitutions and alterations that fall within the spirit and scope of the application are to be understood as being covered by the following claims.
