Problems solved by technology

[0002] Shock absorbers with dampers are widely used, especially in vehicles and other fields. If there is no damping, more unnecessary vibrations will be formed, which will affect the comfort of the vehicle and even affect the life of the vehicle.
However, the dampers are all realized by fluid flow, and the life and function of such shock absorbers are greatly limited

Embodiment 1

[0033] Such as figure 1 The shown electric damping shock absorber comprises a dynamic structural part 1, a static structural part 2 and an elastic element 3, and the elastic element 3 is arranged between the dynamic structural part 1 and the static structural part 2, and the linear electric mechanism The static electromagnetic part 42 is arranged on the static structural part 2, the electromagnetic moving part 41 of the linear electric mechanism is arranged on the moving structural part 1, and the electromagnetic static part 42 and the electromagnetic moving part 41 cooperate electromagnetically. .

[0034] In this embodiment, specifically, the electromagnetic static part 42 is set as an inductive closed coil, and the electromagnetic moving part 41 is set as a permanent magnet.

[0035] As an alternative embodiment, the electromagnetic static part 42 can also be changed to a permanent magnet, and the electromagnetic moving part 41 can be changed to an inductive closed coil. ...

Embodiment 2

[0037] Such as figure 2 Shown electric damper, its difference with embodiment 1 is: change described electromagnetic static part 42 into inductance non-closed coil, change described electromagnetic moving part 41 into permanent magnet, described inductance The non-closed coil communicates with the load 6 via the control unit 5 .

[0038] As an alternative embodiment, the control unit 5 is eliminated, and the inductive non-closed coil is directly connected to the load 6 .

[0039] As a convertible embodiment, the electromagnetic static part 42 is changed to a permanent magnet, and the electromagnetic moving part 41 is changed to an inductive non-closed coil, and the inductive non-closed coil is communicated with the load 6 or via the control unit 5 communicates with load 6 .

Embodiment 3

[0041] Such as image 3 The difference between the shown electric damping shock absorber and Embodiment 1 is that the electromagnetic static part 42 is changed to an inductance non-closed coil, the electromagnetic moving part 41 is set as an excitation magnet, and the inductance non-closed The coil communicates with the power source 7 via the control unit 5 .

[0042] As an alternative embodiment, the control unit 5 is eliminated, and the inductive non-closed coil is directly connected to the power supply 7 .

[0043] As a convertible embodiment, the electromagnetic static part 42 is changed to an excitation magnet, and the electromagnetic moving part 41 is changed to an inductive non-closed coil, and the inductive non-closed coil is communicated with the power supply 7 or via the control unit 5 Connect with power supply 7.

Abstract

The invention relates to a shock absorption device, and in particular to an electric damping shock absorber. The electric damping shock absorber disclosed by the invention comprises a moving structural member, a static structural member and an elastic component, wherein the elastic component is arranged between the moving structural member and the static structural member; the electromagnetic static member of a linear electric mechanism is arranged on the static structural member, the electromagnetic moving member of the linear electric mechanism is arranged on the moving structural member, and the electromagnetic static member is in electromagnetic fit with the electromagnetic moving member; or the electromagnetic static member of a rotary electric mechanism is arranged on the static structural member, the electromagnetic moving member of the rotary electric mechanism is driven by the moving structural member, and the electromagnetic static member is in electromagnetic fit with the electromagnetic moving member. According to the electric damping shock absorber disclosed by the invention, redundant shock is reduced by virtue of damping generated by the interaction of the electromagnetic static member and the electromagnetic moving member, thus a better shock absorption is achieved; a part of energy in shock can also be recovered in a structure provided with an inductive unclosed coil, thus a great effect is also achieved in the aspect of energy saving.

Description

technical field [0001] The invention relates to a shock absorber, in particular to an electric damping shock absorber. Background technique [0002] Shock absorbers with dampers are widely used, especially in vehicles and other fields. If there is no damping, more unnecessary vibrations will be formed, which will affect the comfort of the vehicle and even affect the life of the vehicle. However, the dampers are all realized by fluid flow, and the life and function of such shock absorbers are greatly limited. Therefore, need to invent a kind of novel damping shock absorber. Contents of the invention [0003] An electric damping shock absorber, comprising a dynamic structural part, a static structural part and an elastic element, the elastic element is arranged between the dynamic structural part and the static structural part; the electromagnetic static part of the linear electric mechanism is arranged on the On the static structural part, the electromagnetic moving part ...
