In the present embodiment, main damped part is used as by the second torsional spring 4, elastic slice 5 is used as Auxiliary Damping component, to solve
Having determined has take-off, bow-backed when the upper cover of existing electric cooker is opened, uncap steady, and will not produce because of unbalance stress
Raw double swerve even rubs with other component, greatly improves the service life of complete machine.
Upper cover 6 is opened fully to 90 ° of detailed process and is analyzed as follows by being closed to:
When upper cover 6 is closed (early period), the torque of the first torsional spring 3 is greater than the torque of the second torsional spring 4 and the gravity of upper cover 6 produces
The sum of raw torque, the opening speed of upper cover 6 is zero at this time；
When upper cover 6 continues to open (mid-term), the torque of the first torsional spring 3 is gradually reduced, the torque of the second torsional spring 4 with it is upper
The sum of the torque that the gravity of lid 6 generates is gradually increased, until the torque of the first torsional spring 3 is equal to the torque and upper cover 6 of the second torsional spring 4
The sum of the torque that generates of gravity, at this point, the opening speed of upper cover 6 reaches maximum value；
When upper cover 6 continues to open (later period), the sum of torque that the torque of the second torsional spring 4 and the gravity of upper cover 6 generate is big
In the torque of the first torsional spring 3, the opening speed of upper cover 6 is gradually reduced by maximum, when upper cover 6 is opened to the 8/10 of entire stroke
At position, elastic slice 5 starts to compress, and completes of short duration, a small amount of resilient absorbent, so that buffer function is played for upper cover 6, when upper
When lid 6 is opened to 90 °, the opening speed of upper cover 6 is decreased to zero, at this point, the torque that gravity generates is zero, the torsion of the first torsional spring 3
Square is equal to the torque of the second torsional spring 4, and the rotation section 61 of upper cover 6 is placed in the opening of cancave cambered surface, and 5 stress of elastic slice is zero.
In the opening procedure of upper cover 6, bow-backed phenomenon will not occur for upper cover, solve existing electric cooker or other are uncapped
Hunchback problem existing for product.
