Description
Technical Field
The utility model belongs to the technical field of the new forms of energy electric motor car, concretely relates to new forms of energy electric motor car machine controller base damping device.
Background
At present new forms of energy electric motor car all is equipped with high-voltage electrical apparatus equipment such as machine controller, high-voltage distribution box, unification controller more, and equipment snap-on is alone or on the combination frame, and few shock attenuation measure, along with the new forms of energy electric motor car in the popularization of each trade, the use of various road conditions, vibrations too greatly can be to leading to spare part to damage, machine controller life-span shortens, causes troubles such as outage even, and then influences the normal work of motor. Especially under the working conditions of poor road conditions such as mining areas and suburbs, the vibration generated when the vehicle runs on a bumpy road surface and the vibration generated by the running of the motor can damage the running stability of the motor controller.
SUMMERY OF THE UTILITY MODEL
The utility model provides a new forms of energy electric motor car machine controller base damping device, the technical problem who solves is: reduce the motor controller vibrations, damping is fallen and is made an uproar and support motor controller.
In order to solve the technical problem, the utility model provides a new forms of energy electric motor car machine controller base damping device, its characterized in that: comprises an annular rubber shock pad, a shockproof metal washer and a bolt; two shockproof metal washers clamp an annular rubber shock pad and form a shock attenuation piece, all install a shock attenuation piece between the base of motor controller both sides and the combination frame, connect through bolt, nut.
Has the advantages that: the utility model discloses reduce the vibrations of machine controller, improved the reliability, improved work efficiency. Besides shock absorption, the damping and noise reduction device can also play a role in damping and noise reduction, and simultaneously has a role in supporting the motor controller. The design reduces the loss of the motor controller caused by vibration to the maximum extent, and improves the working efficiency at the same time.

fig. 2 the utility model discloses machine controller base shock-absorbing structure.
Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following description will be made in further detail with respect to the embodiments of the present invention.
The utility model provides a new energy electric vehicle motor controller base damping device, which comprises an annular rubber damping pad 2, shockproof metal gaskets 1 and 3 and a fixing part, wherein the annular rubber damping pad, the shockproof metal gasket and the fixing part are additionally arranged on a motor controller base;
two shockproof metal washers clamp an annular rubber shock pad to form a shock absorption piece, the shock absorption pieces are respectively fixed on the bases 5 at two sides of the motor controller 4, and the shock absorption pieces are arranged on the combined frame and connected through bolts and nuts.
Each motor controller base adopts a structural form that two shockproof metal gaskets clamp one annular rubber shock pad, and the number of the bases is four.
A shockproof metal washer is arranged on the upper surface of a frame, an annular rubber shock pad is assembled on the washer, a shockproof metal washer is arranged on the upper surface of the shock pad, a motor controller falls down, a fixing hole position of a base of the motor controller, the shockproof metal washer and the annular rubber shock pad are in a coaxial position, and finally the shockproof metal washer, the annular rubber shock pad and the motor controller are combined and fixed on the frame through bolts and nuts, so that external shock borne by the motor controller is reduced to a great extent, and reliability is improved.
By the common vibration frequency formula of the shock pad
It is known that increasing the mass (by m) of the structure supporting the shock ring and the shock pad, i.e., increasing the material density and thickness of the support structure, reduces the natural frequency f of the shock pad, and that decreasing the stiffness K of the shock ring and the shock pad, i.e., reducing the stiffness of the shock pad, reduces the natural frequency f of the shock pad.
The motor controller damping device can play a role in damping and noise reduction besides damping, and also has a role in supporting the motor controller. The design reduces the loss of the motor controller caused by vibration to the maximum extent, and improves the working efficiency at the same time.
