Description

Binding type battery-driven car

The present invention relates to dolly, parking area, the automobile of public way, the electric car on recreation ground, sightseeing ground.

In the prior art, accept the vehicle of electric power while travel, representative type has electric car, but the shortcoming of electric car is to need long stringings, and vehicle can not independent action, and vehicle sounds is big etc.

A kind of automobile that is called hybrid car has appearred recently, its dual-purpose engine petrol and electro-motor, and its shortcoming is that exhaust is non-vanishing, and the cost height.Though fuel cell improves every year, need to make the facility of fuel, weight is big in addition.

Though help environment, intrinsic energy is little only to use the battery-driven car (EV car) of battery, motor, must repeatedly charge during long distance travel.

In addition, also have and on the road surface, bury induction coil underground, the technology of (perhaps before four corners and shop stop in) makeup energy in the travelling of car, the shortcoming of this technology is must be provided with much to bury the place underground, while the little energy that travels and replenish.

The vehicle (internal energy types such as automobile, aircraft) that are loaded with whole energy exist problems such as public hazards, fuel cost height, weight are big.And all from the vehicle (external energy type such as electric car) the equipment complexity of outside energize.

The present invention is based on existing battery-driven car (EV car), invented a kind ofly also can replenish big energy under steam, and the few method of (energy supplement is used) cost of equipment (inner, external energy and use type).

Fig. 1 is that battery-driven car of the present invention (hereinafter referred to as the EV car) is driven one of the synoptic map example on the road surface.Among this figure, the 1st, feeding pannel, the 2nd, contact head or inductive head, the 3rd, EV car, the 4th, union lever (plate), the 5th, communication head.Feeding pannel 1 is supplied with vdc (or high frequency voltage) union lever 4 or is built in the interior battery of EV car by contact head (or inductive head) 2 based on source power supply, solar energy source, battery etc.

Among this figure, when the EV car was driven separately, union lever 4 was folded to the car body bottom, can be used as existing EV car and used (though at this moment also obtaining energy from feeding pannel 1, tens of/one when its value is binding).

Binding between the EV car 3, disengaging are carried out automatically.

That is, when the driver wishes automatic steering, specify the destination of travelling with the keyboard in the car, the switch that will " travel automatically " is set at ON.This information passes to another EV car by 1 to 2 communication 5.If this another EV car is when wishing the EV car (hereinafter referred to as EV1) of binding, according to transmitting position, the direction of next information based on the EV car (hereinafter referred to as EV2) of hope binding, calculate and whether can respond to, link, only under possible situation, the data of automatic steering are transferred to EV2 (also can on EV2, adorn electron camera, connecting portion with pattern recognition EV1 links).

The spacing that makes car when automatic steering is near to a certain degree the time, and the union lever at the bottom of the car is stretched out.When following distance further near the time, be considered as linking operation and end, after, EV2 follows the action of EV1 and becomes automatic steering (but braking can manually).

Fig. 2 represents to link an example of end of a period back state.

Among this figure, the connecting part of right part EV2 contacts (being electrically connected) the union lever 6,7 that stretches out from left part EV1 and the figure.

Treatment scheme legend when Fig. 3 represents to link.

During disengaging, undertaken by the switching information that sends from EV1 or EV2 from " travelling automatically " to " manually travelling ".

When sending this information from EV1, vehicle headway is drawn back in follow-up car EV2 braking, withdrawal union lever and finishing.

When sending this information from EV2, at first notify EV1, similarly break away from above-mentioned.

As mentioned above, first scheme of the present invention is to be provided with union lever 4 (electric wireline) on the EV car.

When linking in this wise, even the length of the contact head 2 of feeding pannel side is short, also can deliver to whole EV cars (among Fig. 1, the total contact bar often contacts with contact head 2 with the DP distributing pole of EV car bottom, even also can obtain electric energy for a long time under steam) to electric power by union lever.

Union lever 4 is not only supplied with each EV car to electric power, and can be also used as sensor, and this sensor can make automatic steering become possibility.With Fig. 2 this point is described below.

The right union lever 6 of the driving EV1 of elder generation, the spring 8,9 that left union lever 7 pushes follow-up car EV2 respectively, the amount of compression of establishing at this moment is respectively L1, L2, and the amount of compression of establishing minimax is respectively Lmax, Lmin, and then automatic steering satisfies following formula substantially:

Lmin＜L1 and L2＜Lmax

As long as the left and right sides motor of the follow-up car EV2 of automatic guidance, bearing circle (driving EV1 automatically earlier knocks into the back).

When L1 and L2＞Lmax, as long as EV2 stops.

When L1 and L2＜Lmin, be considered as linking and remove, EV2 becomes first driving.

The following describes automatic steering control.

If the amount of compression of the spring of right angle orientation 10,11 is L3, L4, when L1＞Lmin and L3＞Lmin, with the control setup in the automatic steering signal supply EV2 that turns right, when L2＞Lmin and L4＞Lmin, with the control setup in the automatic steering signal supply EV2 that turns left (still, when L3, L4 steep variation, be considered as abnormal condition, the control that promptly stop).

Above in the said example, be with contact method from feeding pannel to EV car supply capability, and to link be to adopt bar or the such hard object of plate to carry out.

Fig. 4 represent with noncontact method power supply, with the linking belt that is rolled into web-like of softness while the state that links the EV car that travels.

Among this figure, the 1st, feeding pannel (this not shown), in keep battery or send out the machine that shakes, the input line is the formations such as line that commercial power line, solar panels constitute, output is to connect high frequency coil 13.

High frequency coil 13 is made of 2 coils in front and back in this figure, and it is preferably vehicle headway at interval, but also can be 4 to 5m.

In addition, this coil also can be embedded in sheet rubber or resin sheet inside (in addition, the setting of feeding pannel 1 is spaced apart hundreds of rice).

Coil 14 completely is located at EV car 3 bottoms (following the into long setting of direction) with the High frequency power of induction mode acceptance from feeding pannel 1.The 25th, electric wireline that is used to link or soft copper strips etc. in travelling separately, are wound on the rear portion of EV car by the power of spring, when linking, pull out from follow-up car as shown in figure, while keep vehicle headway to travel.

Below with reference to this figure action is described.

The binding of EV car 3, disengaging are said the same with the front.

At first, communication 5 conducting of the communication of supply side 12 and EV car side just in time by above the coil 13, are given EV car driving control signal, more close after, feeding pannel 1 beginning is powered to coil 13.

This High frequency power becomes dc voltage (vdc) after being accepted by the coil 13 of EV car 3 sides, gives coupling plate 25.

Electric power on the coupling plate 25 is used for the motor driven of self or is stored in the battery, is used in other EV car simultaneously similarly.

When the EV car was advanced further, the coil 13 that coil 14 breaks away from the left side of feeding pannel 1 seemed that electric power is cut off, but at this moment because the coil 13 on the right side inserts the coil 14 of next EV car, so electric power supplies to the EV car of last tail always.

Below, be described more specifically the binding of this kind mode.

Fig. 5 is an example of expression takeup type mode of connection principle, and preceding state is represented to link in top, and the state of end of a period is represented to link in the bottom.

Among this figure, when EV car 3 was driven separately, coupling plate 4 was wound on the center link 15 by the power of spring 16.

Common electric wireline 20 and coupling plate 4 are electrically connected, and 15,16,17,20 is one group in the figure, is arranged to 2 groups but also can suitably add and subtract, and also coupling plate can be divided into 2 and be arranged to one group.

As previously mentioned, when conditions being possessed that 2 EV cars 3 link, EV car 3 upper right among Fig. 5 is automatically driven, gradually near upper left EV car among the figure, contact lever 17 leaves on the contrary gradually with above-mentioned after accommodating in the socket 18,19, when reaching vehicle headway, link and finish.

Fig. 6 is that the expression coupling plate is undulatory situation.

When driving separately, coupling plate 4 is housed in EV car 3 inside foldedly, during binding, is pulled out to follow-up car shown in figure below among the figure.

The EV car is bonded as described above, at least follow-up car automatic steering, the data that are used for automatic steering are except by the aforesaid union lever itself, also can by between the communication 5, the reception transmission of the communication of feeding pannel 12 and communication 5 or artificial satellite and communication 5 obtains.

The advantage of automatic steering is that except the automatic supply of electric power, even also can drive in bed at a distance always, the no one also can call out, and when this system is implemented on public way, exists the checking of safety, the significant problems such as modification of road traffic law.Can be earlier in recreation ground, factory place, golf field, the ground of going sightseeing etc. locate utilization.In order to ensure safety, be preferably in camera, audifier recorder are set on the EV car, shoot with video-corder reflection, the sound of the car that hinders forward march etc., the device that transmits information (with communication 5) to feeding pannel and public loop is set.
