Variable durometer material is stirred evenly in the thermoplastic material of the elastic rubber material addition fine particle shape of liquid
And air is blasted, and it is molded the elastomer of manufactured spongy porous structure at a certain temperature, porous structure is conducive to radiate,
Thermoplastic material can be allowed to cool down as soon as possible to revert to original state after resistance wire power-off；
Current control unit is separately connected entire car controller, on-vehicle battery and resistance wire, and by adjusting on-vehicle battery
The size of current for being transmitted to resistance wire carrys out the calorific value of regulation resistance silk, and current control unit is configured as：
Driver's operation information from entire car controller is received, it is electric when driver select driving mode for motor pattern
Flow control unit disconnects on-vehicle battery and resistance wire, and helical spring is during compression and rebound due to by the anti-of conveyor screw
The hardness of active force, coil spring assembly is higher, and suspension is made more to meet the driving demand of motor pattern；When driver will drive mould
Formula is switched to comfort mode by motor pattern, and current control unit is connected to on-vehicle battery and resistance wire, makes resistance wire heating power,
To make the thermoplastic material in conveyor screw so that suspension is more accorded with so that the hardness of coil spring assembly reduces by thermal softening
Close the driving demand of comfort mode；
Under comfort mode, current control unit also receives the vibration signal from chassis shock sensor, when vibrations width
Degree is more than predetermined value and the duration is more than scheduled duration, shows vehicle just traveling on the road surface more jolted, at this time electric current
Control unit tunes up current value, and the hardness of coil spring assembly is made to further decrease, so as on the track to jolt still
Preferable comfort can be kept, is more than scheduled duration, current control unit when vibration amplitude is less than predetermined value and duration
Current value is reverted into initial size.
Preferably, current control unit also receives the signal from front truck radar, current vehicle radar detection to vehicle front
There are barrier in preset range, vehicle needs to carry out emergency braking immediately, and emergency braking will bring vehicle body by a relatively large margin
Pitching, in order to inhibit this pitching as possible, then no matter which kind of current driving mode is, current control unit all disconnects vehicle-mounted
Battery and resistance wire.
The thermoplastic material refers to that fusing point is low, easily by the material of thermal softening, be such as, but not limited to vinyon or
Igelite.
By means of the invention it is possible to its hardness is dynamically adjusted according to driver's operation information and running condition information, to
So that the soft or hard degree of electric vehicle suspension is more met the requirement of driving, optimize driving experience, and it is relative to air spring
For, it is simple in structure, it can directly install additional and realize on the basis of conventional absorber spring, reduce cost.

Specific implementation mode
With reference to the accompanying drawings, the function that the structure of the present apparatus is described in detail and is realized.
Coil spring assembly 1 include helical spring and conveyor screw 3, conveyor screw 3 by band-like variable durometer material spirally
It is formed, is set around between adjacent two spring silks 2 of the central section of helical spring, the both ends in width direction and spring silk 2
Fixed adhesion, the width of conveyor screw 3 are approximately equal to the screw pitch of helical spring, and thickness is approximately equal to the spring filament diameter of helical spring, spiral
More conductive resistance wires 4 are equipped in body 3；
Variable durometer material is stirred evenly in the thermoplastic material of the elastic rubber material addition fine particle shape of liquid
And air is blasted, and it is molded the elastomer of manufactured spongy porous structure at a certain temperature, porous structure is conducive to radiate,
Thermoplastic material can be allowed to cool down as soon as possible to revert to original state after the power-off of resistance wire 4；
Current control unit 5 is separately connected entire car controller 7, on-vehicle battery 6 and resistance wire 4, and vehicle-mounted by adjusting
The size of current that battery 6 is transmitted to resistance wire 4 carrys out the calorific value of regulation resistance silk, and current control unit 5 is configured as：
Driver's operation information from entire car controller 7 is received, it is electric when driver select driving mode for motor pattern
