Example 1
As shown in fig. 1 in conjunction with fig. 2 and 3, the lid-turning mechanism for a trash can of the present embodiment mainly includes two radial arms 10, a driving device 20, and a transmission device 30 for realizing transmission coupling between the two radial arms 10 and the driving device 20. The specific coupling between the two swing arms 10 and the transmission device 30 is as follows:
one end of each of the two swing arms 10 is used for being fixed with one side edge of a can cover 40 of the garbage can and is approximately symmetrically arranged at the left part and the right part of the side edge of the can cover 40; the two swing arms 10 are fixed with rotating shafts 11, and the rotating shafts 11 are fixed with first transmission gears 12.
The position of the transmission device 30 is approximately between the two swing arms 10, and the transmission device 30 includes a transmission rod 31 and two second transmission gears 32 fixed at two ends of the transmission rod 31. The second transmission gear 32 disposed at the left end of the transmission rod 31 is engaged with the first transmission gear 12 on the rotating shaft 11 of the left swing arm 10, and the second transmission gear 32 disposed at the right end of the transmission rod 31 is engaged with the first transmission gear 12 on the rotating shaft 11 of the right swing arm 10. When the transmission rod 31 rotates, the two swing arms 10 can be driven to rotate synchronously.
The driving device 20 is a motor, and is in transmission connection with the transmission rod 31, specifically:
as a coupling, the transmission rod 31 is directly fixed with the output shaft of the driving device 20 (not shown in the figure); alternatively, the first and second electrodes may be,
as another coupling method, an output gear 21 is fixed to the output shaft of the driving device 20, and the output gear 21 is engaged with any one of the transmission gears on the transmission rod 31. Preferably, a third transmission gear 33 is further sleeved and fixed on the outer side of the middle portion of the transmission rod 31, and the output gear 21 on the output shaft of the driving device 20 is meshed with the third transmission gear 33, so that the structure between the driving device 20 and the transmission device 30 is more compact, and the utilization rate of the installation space is improved.
In the flip-open mechanism, the transmission rod 31 of the transmission device 30 and the rotating shafts 11 on the two swing arms 10 are rotatably fixed on the can body 50 of the trash can, and the driving device 20 is also fixed on the can body 50 of the trash can. When the driving device 20 operates, the driving rod 31 is driven to rotate so as to drive the two swing arms 10 to rotate at the same time, and then the barrel cover 40 is driven to rotate around the rotating shafts 11 on the two swing arms 10, so that the barrel cover 40 is integrally, synchronously, stably and automatically opened and closed.
Further, all the cover is equipped with one or more torsional springs 13 on the pivot 11, both sides tip 130 of torsional spring 13 all stretches out towards the radial direction of torsional spring 13.

When the barrel cover 40 is closed, the barrel cover 40 presses towards the barrel body 50, so that impact collision is easy to generate, and a reaction force is generated between the two end parts 130 of the torsion spring 13 to play a role in buffering, so that strong impact between the barrel cover 40 and the barrel body 50 is avoided.
In addition, when the tub cover 40 is in the closed state, the torsion spring 13 is in the initial state, and the torsion spring 13 is set to the compression state: at this time, assuming that the tub cover 40 substantially uses the torsion spring 13 as a rotation axis, the tub cover 40 generates a torque T1 due to gravity, the torsion spring 13 generates a torque T2 due to a compressed state, the torque T2 is opposite to the torque T1, and the modulus of the torque T2 is not greater than that of the torque T1. The advantage of this arrangement is that the torsion spring 13 provides a certain support for the barrel cover 40, and the driving device 20 only needs to output a small torque to drive the barrel cover 40 to turn upwards and open, so that the load of the driving device 20 is reduced, and the energy consumption is reduced.
Further, the outer sides of the two swing arms 10 are further fixed with damping devices 14, the damping devices 14 are made of rubber or silica gel, and are used for avoiding direct collision between the barrel cover 40 and the barrel body 50, so that the overturning process of the barrel cover 40 is more stable, the damping device also has the effect of damping, and noise is reduced.
Preferably, the radial arm 10 includes a body 100 and two connecting lugs 101 fixedly connected to the outside of the lateral edges of the body 100, and the lateral shape of the body 100 of the radial arm 10 is substantially arc-shaped. Two engaging lugs 101 of the swing arm 10 are sleeved and fixed on the outer side of the rotating shaft 11, the end part of the inner side of the rotating shaft 11 penetrates out of the engaging lug 101 of the inner side, and the first transmission gear 12 is fixed on the end part of the inner side of the rotating shaft 11. In this way, an open space 102 is formed between the body 100 of the swing arm 10 and the engaging lug 101 so as to accommodate accessories such as the torsion spring 13.
Preferably, the driving device 20 is a speed reduction motor to enhance stability.
Further, the driving device 20 is further provided with an encoder 22 for acquiring a rotation angle of the output shaft of the driving device 20, and the rotation angle of the swing arm (equivalent to a rotation opening and closing angle of the barrel cover) can be obtained through simple conversion. Preferably, the encoder 22 is a grating encoder to improve the detection accuracy, and the installation requirement of the grating encoder is low. The encoder 22 is a conventional product, and therefore, the internal structure thereof will not be described.
