On ground or wall or vertical truss.
Preferably, electric vehicle includes two-wheeled motor bicycle, electro-tricycle, four-wheel electric motor car (such as new energy passenger car, bus
Vehicle and special purpose vehicle etc.).
Receiver 2 and transmitter 3 by the connection type of wireless signal, are made charging unit get rid of route by the present invention
Limitation, charging process is simple and convenient, reduces the trouble of plug, is easy to normal user operation, has flexibility, realizes electric appliance
With the contactless connection of power supply, by contactless electrically connected, it is not applicable to avoid interface, fever, fire caused by poor contact
The safety accidents such as calamity, safety greatly increase, and show vast potential for future development.
If electric energy transmission part is horizontally mounted by the present invention, i.e., transmitting disk 3 and take-up reel 2 are horizontally mounted, take-up reel 2 fills
Set on the bottom of electric vehicle 6, emit disk 3 and be installed on ground, due to ground at a distance from electric vehicle 6 farther out, cause wireless charging
The consume of electricity is larger.
Should guarantee that the operating distance of charging unit is short, again guarantee vehicle driving when gap it is sufficiently large, the two cannot
It combines.To meet charging requirement, in order to improve the efficiency of charging, after electric vehicle 6 stops in place, to make to emit disk to moving up
Dynamic, close to take-up reel, reaching suitable distance could charge.
Take-up reel 2 and transmitting disk 3 are horizontally mounted and have the following problems:
Transmission efficiency is low: to guarantee that vehicle can have in the traffic capacity in rugged and rough location, bottom and the ground of electric vehicle 6
One is greater than the ground gap of 100mm, and to guarantee normal driving, which can make transmitting disk 3 larger at a distance from take-up reel 2, to drop
The coupling coefficient of low transmission system reduces efficiency of transmission, these also increase the transmitting of transmitting disk 3 in addition to the energy consumption for increasing charging
Power increases operating cost and manufacturing cost；
Constructional difficulties: need to be in underground excavation melt pit, the installation transmitting disk 3 in melt pit, power cable also needs buried, wants simultaneously
Consider moisture-proof pressure-bearing factor, difficulty of construction is big, if necessary to increase the transmission power of transmitting disk 3, needs to install for going up and down hair
The lifting device of disk 3 is penetrated, construction cost is higher；
It is inconvenient for use: because structure is complicated, to be not easy to realize standardization, when charging needs that 3 liters of disk will be emitted by lifting device
Drop makes take-up reel 2 and transmitting disk 3 be close to suitable position, inconvenient；
Place is restricted: because of the installation electric device in melt pit and device part is raised on ground.Row on the ground
It walks and other purposes is limited；
Difficult in maintenance: transmitting disk is mounted in melt pit, easy ponding dampness, and upper surface, which has wheel, rolls and trample with pedestrian,
And easily dampness is pressurized damage in use, and disassembly is difficult when maintenance, and take-up reel is mounted on the bottom of electric vehicle, and when maintenance will bore
Enter the maintenance of vehicle bottom, repair and maintenance difficulty is big, and maintenance cost is higher, is also not easy to integrate other intelligent communication components；
Safety is poor: because transmitting disk be horizontally arranged at ground, if any metallic foreign body (such as key, coin or crown cap, easily
Draw tank etc.) when being scattered on transmitting disk 3, foreign matter can electromagnetic wave absorption fever, not only consume electric energy, and foreign matter can be made to generate heat
(or even burn red) causes fire, therefore, must carry out foreign bodies detection before charging, detects after must clearing up foreign matter after foreign matter
It can charge, and melt pit easily intakes, makes equipment moisture damage.
Preferably, by electric energy transmission part vertical (or approximate angle) installation, i.e., transmitting disk 3 and take-up reel 2 are vertically pacified
Take-up reel 2, is vertical at one end of electric vehicle by dress, and transmitting disk 3 is vertical at fixed device side, when the two is close,
Electric energy wireless transmission can be achieved, the plug and charging adapter without attaching plug arrange storage operation；
The advantages of emitting disk and take-up reel right angle setting:
Efficiency of transmission is high: the distance of transmitting disk 3 to take-up reel 2 can accomplish 10-50mm, and low energy consumption for charging, high-efficient, manufacture
It is at low cost；
Easy for construction: transmitting disk is not necessarily in melt pit, without excavating ground, is not necessarily to buried cable, installation and construction party
Just, difficulty of construction is small and cost is relatively low；
Easy to use: structure is simple, easily realizes that standardization, take-up reel are set to the tailstock or headstock (or the other conjunctions of electric vehicle
Suitable position), when charging, need to only move vehicle and alignment and positioning can be completed, without separately setting the fortune of transmitting disk or take-up reel alignment positioning
Motivation structure (such as mechanical arm)；
Place is without limitation: without melt pit and buried component, to the purposes in place without limitation；
Easy to maintain: take-up reel 2 is mounted on one end of the car body of electric vehicle, and transmitting disk 3 is set on fixed device, no dampness
Compression phenomenon, not easily damaged, maintenance difficulties are small, at low cost, and are advantageously integrated Communication Control, the components such as charging accounting, increase
User experience interest；
Highly-safe: transmitting disk 3 and take-up reel 2 are installed perpendicular to ground, are not had on foreign matter is scattered, will not be generated different
Hidden danger red and on fire is burnt in object fever, and use is safe, to reduce the detection and cleaning of transmitting disk before charging.
The foregoing is merely preferred embodiments of the present invention, are not intended to limit embodiments of the present invention and protection model
It encloses, to those skilled in the art, should can appreciate that all with made by description of the invention and diagramatic content
Equivalent replacement and obviously change obtained scheme, should all be included within the scope of the present invention.
