Detailed Description
The invention is further described with reference to the following drawings and specific embodiments.
Referring to fig. 1, a small cap coupling structure 1 of the present embodiment is used to couple a small cap 2 and a large cap 3.
Referring to fig. 2, the small lid coupling structure 1 includes a small lid rotating shaft 10 fixed to one side of the small lid 2, and a link mechanism 11 rotatably coupled to the small lid rotating shaft 10. One end of the link mechanism 11 is connected with the 4 motors.
Referring to fig. 3, the link mechanism 11 preferably includes a first link 12 and a second link 13. One end of the first link 12 is fixed with the output shaft of the motor 4, and the motor 4 drives the first link 12 to rotate when running. The other end of the first connecting rod 12 is hinged with one end of the second connecting rod 13, and the other end of the second connecting rod 13 is hinged with the small cover rotating shaft 10.
Preferably, the first connecting rod 12 is in transmission connection with the output shaft of the motor 4 through a detachable key structure, and a flat key or a spline structure can be adopted.
Referring to fig. 4 and 5 in combination with fig. 2, the large lid 3 is provided with an opening 30, and an accommodating space 31 is provided inside the opening 30.
The motor 4 is disposed in the accommodating space 31 and fixed with the large cover 3. The small lid coupling structure 1 may be partially or entirely accommodated in the accommodation space 31.
Fig. 4 and 5 show the coupling structure between the small lid 2 and the large lid 3 when the small lid 2 is in the uncapped state. When the small cover 2 is closed, the motor 4 is started and drives the first connecting rod 12 to rotate clockwise. The second link 13 is rotatably coupled to the first link 12 and the small lid rotating shaft 10, so that when the first link 12 rotates clockwise, the second link 13 is pulled to rotate relative to the first link 12, and the second link 13 also moves in the right-down direction integrally around the motor 4.
The small lid rotating shaft 10 is further provided with a first connecting portion 14, and a matching groove 15 is defined between the first connecting portion 14 and the body of the small lid rotating shaft 10.
The large lid 3 is provided with a second coupling portion 32 on a side of the opening 30 adjacent to the edge of the large lid 3. The second coupling portion 32 may be integrally formed with the large lid 3.
The fitting groove 15 of the small lid hinge 10 is fitted over the outside of the second coupling portion 32 of the large lid 3. Specifically, a part of the side wall of the fitting groove 15 abuts against the second coupling portion 32. With reference to the view direction shown in fig. 5, the end of the second link 13 is coupled to the left portion of the small lid rotary shaft 10, and the second coupling portion 32 abuts against the right portion of the small lid rotary shaft 10. Therefore, when the end of the second link 13 coupled with the small lid rotation shaft 10 moves downward, the small lid rotation shaft 10 is pulled to rotate counterclockwise around the position where the fitting groove 15 abuts against the second coupling portion 32, and the small lid 2 is driven to rotate counterclockwise to the left until it is closed with the large lid 3.
The cover opening process is the reverse process of the cover closing process, the motor 4 reversely rotates to drive the first connecting rod 12 to rotate anticlockwise and upwards, meanwhile, the second connecting rod 13 integrally moves upwards around the motor 4, the left end of the small cover rotating shaft 10 is jacked up, so that the small cover rotating shaft 10 rotates clockwise around the position where the matching groove 15 abuts against the second connecting part 32, and synchronously, the small cover 2 rotates clockwise to open the cover.
Preferably, the small cover rotating shaft 10 is fixed in the middle of the edge part of the small cover 2, so that the left part and the right part of the small cover 2 are stressed more uniformly and are not easy to deform.
Furthermore, an elastic device is arranged between the small cover 2 and the large cover 3.
Preferably, as shown in fig. 2 and 6, in the present embodiment, the elastic means is one or more torsion springs 5. Each torsion spring 5 has two torsion arms 50, wherein one torsion arm 50 of the torsion spring 5 abuts against the small lid rotation shaft 10, and the other torsion arm 50 of the torsion spring 5 abuts against the large lid 3. During the closing of the small cover 2, the torsion spring 5 is compressed to play a role of buffering; when the small cover 2 is in a closed state, the torsion spring 5 is in a compressed state, and applies torque to the small cover 2, so that when the small cover 2 is opened, the load of the motor 4 can be reduced. At this time, the motor 4 can drive the small cover 2 to rotate by outputting smaller torque than the torsion spring 5 which is not provided in a compressed state.
Preferably, one torsion arm 50 of the torsion spring 5 abuts against said first coupling portion 14 on the small lid spindle 10, and the other torsion arm 50 of the torsion spring 5 abuts against said second coupling portion 32 on the large lid 3.
The embodiments of the present invention are only used for illustration, and do not limit the scope of the claims, and other substantially equivalent alternatives that can be conceived by those skilled in the art are all within the scope of the present invention.
