Description
Technical field
The present invention relates to intelligent automobile field, particularly relate to a kind of piezoelectric type intelligent automobile suspension vibration energy recycle device.
Background technology
At present, existing intelligent automobile mostly is electric automobile, and battery is the energy source of its power and electronic electric equipment.Vibration can be produced through uneven road surface, if these vibrational energies can be reclaimed and to battery charging, the performance of intelligent automobile can be improved undoubtedly in intelligent vehicle running process.Existing Vehicle Suspension Vibration energy regenerating generation technology mainly contains: the energy generating of hydraulic pressure, induction generating and piezoelectric type generate electricity three kinds.Patent CN201010108889.7, CN201110292445.8, CN201210140401.8 and CN201210140411.1 are the energy generating of hydraulic pressure, store by vibrational energy being converted into hydraulic energy, recycling electrical power generators, this generation technology efficiency is not high, and power generation loss is larger.Patent CN201020159667.3, CN201210150249.1 and CN201210558518.8 are induction generating, by arranging magnetic field on suspension, utilize cutting magnetic induction line movement power generation in suspension vibration process, this generation technology voltage is less, energy density is not high, simultaneously larger by size impact.Piezoelectric type generation technology energy density is large, and generating efficiency is high, simultaneously also not by size impact, therefore compares first two forms of electricity generation and has more advantage.Although patent CN201310100451.8 is piezoelectric type generating, it, by realizing barrel type hydraulic shock absorber repacking, destroys original suspension frame structure, and the form be simultaneously suitable for is comparatively single.
Summary of the invention
For prior art Problems existing and defect, a kind of Novel pressure electric-type intelligent automobile suspension vibration energy recycle device is proposed.
The present invention is for solving the problems of the technologies described above by the following technical solutions:
A kind of piezoelectric type intelligent automobile suspension vibration energy recycle device, comprising: suspension on bearing spring, piezoelectric patches, bearing spring and bearing spring lower support.Wherein, bearing spring suspends and is made up of upper suspension terminal pad and upper suspended rubber boss, upper suspension terminal pad and upper suspended rubber boss are consolidated, and upper suspension terminal pad has bolt hole, and on whole bearing spring, suspension utilizes bolt to be connected with vehicle body by bolt hole.Piezoelectric patches is made up of piezoelectric and insulating material, central aperture, is set on suspended rubber boss.Be pressed in bearing spring lower support under bearing spring, utilize upper suspended rubber boss location simultaneously, and on be pressed on piezoelectric patches.Whole device is just reequiped spring-mounted upper suspension, has been set with piezoelectric patches, has not damaged suspension frame structure, and piezoelectric patches and upper suspension simultaneously by designing different size just go for multiple suspension frame structure.
When intelligent automobile travels at uneven road surface, bearing spring compresses because of tire vibration (upper jumping and lower jumping) or stretches, thus drive piezoelectric patches distortion, piezoelectric patches produces direct piezoelectric effect and discharges, can be charged to the battery of intelligent automobile by the process such as rectification circuit and capacitance energy storage afterwards, thus achieve the recycling to vibrational energy.
The present invention adopts above technical scheme compared with prior art, has following technique effect:
1. energy density is large, and generating efficiency is high;
2., not by size and structure influence, be suitable for multiple suspension;
3. structure is simple, easy to use, lasting, non-maintaining.
Accompanying drawing explanation
Fig. 1 is the structural representation of this piezoelectric type intelligent automobile suspension vibration energy recycle device.
In figure, 1-suspends terminal pad, the upper suspended rubber boss of 2-, 3-piezoelectric patches, 4-bearing spring, 5-bearing spring lower support.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
As shown in Figure 1, the invention discloses a kind of Novel pressure electric-type intelligent automobile suspension vibration energy recycle device, comprising: above suspend terminal pad 1, upper suspended rubber boss 2, piezoelectric patches 3, bearing spring 4 and bearing spring lower support 5.Wherein, upper suspension terminal pad 1 has bolt hole, is connected with vehicle body by bolt.Upper suspended rubber boss 2 is the elastic rubber of longitudinal section inverted trapezoidal, it is cemented on suspension terminal pad 1, upper suspension terminal pad 1 and upper suspended rubber boss 2 common composition bearing spring suspend, for supporting, locating bearing spring 4, and connects suspension and vehicle body.The disk lamellar body that piezoelectric patches 3 is made up of jointly piezoelectric and insulating material, its central aperture, is sleeved on the inverted trapezoidal boss of suspended rubber boss 2, and leaves gap with the bottom platform of upper suspended rubber boss 2, is beneficial to piezoelectric patches 3 and is out of shape.Top, bearing spring 4 top is pressed on piezoelectric patches 3, and make piezoelectric patches 3 have certain precompressed initial deformation, bottom is pressed in bearing spring lower support 5, and by the boss of upper suspended rubber boss 2 and the groove location and installation of bearing spring lower support 5.
When intelligent automobile travels at uneven road surface, tire rises and falls with road surface and upper jumping and lower jumping produce vibration, bearing spring 4 is caused to compress or stretch, thus drive piezoelectric patches 3 produces distortion in various degree, piezoelectric patches 3 produces direct piezoelectric effect and discharges, can be charged to the battery of intelligent automobile by the process such as rectification circuit and capacitance energy storage afterwards, thus achieve the recycling to vibrational energy.
For most spring suspension structure, this technical scheme only need design upper suspension and the piezoelectric patches 3 of different size, can realize good adaptation, also can not damage suspension frame structure simultaneously.This technical scheme structure is simple, and not by size and structure influence, energy density is large, and generating efficiency is high, easy to use, lasting, non-maintaining, has vast potential for future development.
