To the damping torque of mechanical damping hinge, damage caused by door and window quick crowbar is avoided, but existing mechanical damping hinge is equal
Using hydraulic structure, hydraulic device is also easy to produce oil leakage phenomenon due to production technology etc., and hydraulic oil has inflammability, so machine
Tool damp hinge cannot be used on fire-proof doors and windows, and hydraulic oil can become viscous at low ambient temperatures, loses ideal damping and makees
With often resulting in and be closed not tight problem.
Utility model content
The purpose of this utility model is to provide a kind of electromagnetic damping buffer hinges, do not have to solve existing damp hinge
There is the problem of fire protection requirement, not applicable low temperature environment.
To achieve the above object, the utility model provides a kind of electromagnetic damping buffer hinge comprising step-up gear,
Motor, rocking bar, connecting rod and fixing seat, the step-up gear include input shaft and output shaft, and the input shaft is located at described
The one side of step-up gear, the output shaft are located at the another side of the step-up gear, and the motor is fixed on institute
State the side wall of step-up gear, the output axis connection of the motor shaft of the motor and the step-up gear, the motor
Positive and negative anodes be connected to form closed circuit, one end of the rocking bar and the input shaft of the step-up gear are fixed, described to shake
The other end of bar and one end of the connecting rod are hinged, and the other end of the connecting rod is hingeably secured to the fixing seat.
Wherein, the step-up gear is multi-stage acceleration gear-box.
Wherein, the step-up gear is second level step-up gear.
Wherein, the rocking bar and the connecting rod are cylindrical rod or plate shape bar.
Wherein, the motor is dc motor.
The utility model has the following advantages that：
The utility model provides a kind of electromagnetic damping buffer hinge, and step-up gear and fixing seat are separately mounted to door
Window and sash, when door and window is by external force, the angle between door and window and sash changes, and passes through the work of rocking bar and connecting rod
With so that the output shaft of step-up gear drives motor operation, since the positive and negative anodes of motor are closure, at this time motor
Stator and rotor relative rotation, cutting magnetic line form induced current and simultaneously generate damping, prevention motor operation, and then counter make
It prevents from damaging so that the angular speed of the folding of door and window reduces used in rocking bar and connecting rod, according to the rule of electromagnetic damping, outside
The speed that power causes door and window to be closed is bigger, and the damping force of generation is also bigger；And it due to using electromagnetic damping, can apply anti-
On the door and window that fire requires, and there is no hydraulic device, is not influenced by low temperature environment, effectively solve existing damp hinge and do not have
There is the problem of fire protection requirement, not applicable low temperature environment.
In addition, the electromagnetic damping of the utility model can reduce the resonance amplitude of mechanical structure, avoid mechanical structure because
Stress, which reaches capacity, causes mechanism collapse；After facilitating door and window by temporary impact, stable state is quickly recovered to；Effectively press down
System resonance, to reduce mechanical noise；Reduce the transmitting of vibration；In the vibration insulation structure design of mechanical system, reasonably transport
With the damping structure of the utility model, the significant effect of vibration isolation, vibration damping is enabled to improve.

Specific embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
Embodiment 1
As shown in Figure 1, embodiment 1 provides a kind of electromagnetic damping buffer hinge comprising step-up gear 1, motor
2, rocking bar 3, connecting rod 4 and fixing seat 5, step-up gear 1 include input shaft (not shown) and output shaft (not shown),
Input shaft is located at the one side of step-up gear 1, and output shaft is located at the another side of step-up gear 1, and motor 2 is fixed on increasing
The side wall of fast gear-box 1, the motor shaft of motor 2 and the output axis connection of step-up gear 1, the positive and negative anodes connection of motor 2
To form closed circuit, one end of rocking bar 3 and the input shaft of step-up gear 1 are fixed, defeated to be converted to the swing of rocking bar 3
Enter the rotation of axis, one end of the other end and connecting rod 4 of rocking bar 3 is hinged, and the other end of connecting rod 4 is hingeably secured to fixing seat 5.
In use, a kind of fixed form is that step-up gear 1 is fixed on door and window 6, fixing seat 5 is fixed on sash 7
Or wall, another fixed form are that fixing seat 5 is fixed on door and window 6, by step-up gear 1 be fixed on sash 7 or
Wall, two kinds of fixed forms.
Electromagnetic damping buffer hinge provided in this embodiment does not use hydraulic oil, is not easy to cause fire, successfully avoid existing
The low embarrassment of damp hinge fire protecting performance, and electromagnetic damping can be suitable for various not by the influence of temperature, especially low temperature
Environment.
In the present embodiment, step-up gear 1 is multi-stage acceleration gear-box, preferably second level step-up gear.
In the present embodiment, rocking bar 3 and connecting rod 4 are cylindrical rod or plate shape bar.
In the present embodiment, motor 2 is dc motor.
As shown in Fig. 2, electromagnetic damping buffer hinge provided in this embodiment is in motion state, if the length of connecting rod 4 is
L1, the length of rocking bar 3 are L2, and the angular speed of door and window 6 is ω 1, and the angular speed of door and window 6 is steady state value, the phase of rocking bar 3 and door and window 6
Angular velocity is ω 2, and door and window 6 and the angle of sash 7 are θ, and the input shaft of step-up gear 1 is between door and window 6 and sash 7
The distance of hinge be L3, mounting base 5 is at a distance from the articulated position to the hinge between door and window 6 and sash 7 of connecting rod 4
L4, then the relationship of ω 1 and ω 2 be：
As ω 1=0.52rad/s, L4=L3=0.115m, functional image is as shown in figure 3, when 0<θ<When π, F` (θ)>0
(derived function of angular velocity omega 2 is greater than zero), i.e., during door and window 6 is at the uniform velocity closed, the revolving speed of the input shaft of step-up gear 1
Slowly increase, so that output shaft revolving speed increases, the revolving speed of motor is also increased with it, and electromagnetic damping power increases.
As L3=L4, as θ → π, 2 →+∞ of ω, i.e., when installing hinge, mounting base 5 is made to level off to door and window 6 and door
Hinge between window frame 7, in this way, the revolving speed of the input shaft of step-up gear 1 can become when door and window 6 is close to when being closed completely
It is very big so that electromagnetic damping power can also become very large, effectively prevent door and window 6 to damage.
