AI Technical Summary
The small size of the drive motor in existing electric toilet lids results in insufficient output torque, making it difficult to start and causing an abnormal increase in current, which affects normal use.
By adding a rotational assist structure to the hinge, the spring force is used to assist the hinge rotation through the cooperation of the slider and the spring, thereby reducing the load on the drive motor.
This increases the torque of the hinge rotation, reduces the load on the drive motor, ensures normal motor operation, and avoids triggering the circuit protection mechanism.

[0017] The utility model makes further elaboration and illustration in combination with specific embodiment and description accompanying drawings:
[0018] Please refer to Figures 1 to 3The utility model provides a kind of rotary push assist force hinge, including shell 10 and rotating shaft 20, rotating shaft 20 includes boss 21 and rotating handle 22, boss 21 is rotationally arranged in the inside of shell 10, rotating handle 22 extends out the side of shell 10, first inclined block 23 is arranged in the inside of boss 21, shell 10 is further provided with sliding block 11, sliding block 11 is slidably connected with shell 10, and shell 10 limits the rotation of sliding block 11, one end of sliding block 11 is arranged in the inside of boss 21, second inclined block 111 is provided on the surface of sliding block 11 corresponding to first inclined block 23, first inclined block 23 and second inclined block 111 are slidably connected, rotating shaft 20 moves by rotating to push sliding block 11, and spring 12 is further provided in the inside of shell 10, spring 12 is arranged on the side of sliding block 11 away from rotating shaft 20.
[0019] Please refer to Figure 4 When using, shell 10 is fixed on equipment, rotating handle 22 of rotating shaft 20 extending out of shell 10 is fixedly connected with cover plate, when cover plate is in closed position, the contact area of first inclined block 23 on boss 21 and second inclined block 111 is located at the end of both, to push sliding block 11 to compress spring 12, so that the inside of hinge keeps the elastic force of pushing sliding block 11, but because the gravity of cover plate is greater than the elastic force of spring 12, so cover plate cannot be automatically lifted and kept in closed position.
[0020] Please refer to Figure 5 When the motor end of cover plate is powered to rotate in lifting direction, cover plate drives rotating shaft 20 to rotate, to make first inclined block 23 slide along second inclined block 111, sliding block 11 is pushed along shell 101 by the reset force of spring 12, because sliding block 11 is limited to rotate and can only move by shell 10, second inclined slope pushes first inclined slope towards the slope of rotating shaft 20, at this time, rotating shaft 20 is subjected to two components of axial and circumferential, but because the axial movement space of shaft is limited by the end face of shell 101, circumferential can move, so rotating shaft 20 rotates, when the resultant force of motor rotating force and the rotating force of hinge is greater than the weight of cover plate, cover plate is lifted until completely opened.
[0021] So the elastic force of spring 12 is used to assist the rotation of hinge when opening, improve the torsion of hinge rotation, reduce the load of driving motor
[0022] In the above scheme, shell 10 includes shell 101 and end cover 102, end cover 102 is fixed on one side of shell 101 by screw 103, and end cover 102 is provided with guide column 104 near the center of one side of shell 101, spring 12 is sleeved outside guide column 104, guide column 104 can limit the position of spring 12, and sliding block 11 can slide along guide column 104, to limit the purpose.

[0024] The gasket 13 is arranged between the inner wall of the shell 10 and the boss 21, and the end face friction between the boss 21 of the rotating shaft 20 and the inner wall of the shell 10 is reduced through the gasket 13. The rotating handle 22 is in a flat structure, so that when the rotating handle 22 passes through the shell 10, the rotating handle 22 and the cover plate can better avoid mutual rotation, and the rotating handle 22 and the cover plate can be better fixed.
[0025] The number of the first inclined blocks 23 is two, and the two first inclined blocks 23 are arranged at 180 degrees, and the number of the second inclined blocks 111 corresponds to that of the first inclined blocks 23, so that when the rotating shaft 20 rotates, the slider 11 can be better pushed to move from both sides, and the slider 11 is more stable under stress.
[0026] The utility model provides a kind of rotary push force assisting hinge, when using, shell is fixed on equipment, rotating handle of rotating shaft extends out the shell and is fixedly connected with cover plate, when cover plate is in closed position, the contact area of first inclined block and second inclined block on boss is located both ends, to push slider to compress spring, so that the inside of hinge keeps the spring force of pushing slider, but because the gravity of cover plate is greater than the spring force, so cover plate will not automatically lift and keep in closed position;When the motor end of cover plate is powered to rotate in lifting direction, cover plate drives rotating shaft to rotate, so that slider is not limited by first inclined block, and slider slides along shell under the push of spring reset force, because slider is limited to rotate only by shell, second inclined slope pushes first inclined slope towards the slope of rotating shaft, at this time, rotating shaft is subjected to two components of force, axial and circumferential, but because the axial movement space of shaft is limited by the end face of shell, circumferential can move, so rotating shaft rotates, when the resultant force of motor rotation force and hinge rotation force is greater than the weight of cover plate, cover plate is lifted, until completely open, so that the spring force is used to rotate hinge when opening, play auxiliary role, improve the torsion of hinge rotation, reduce the load of driving motor.
