Description

Trolley electric vehicle {trolley electric power vehicle}

The present invention relates to a trolley electric vehicle, maximizing the advantages of the conventional trolley electric vehicle and at the same time to solve the shortcomings, compared to the conventional battery-powered electric vehicles, hydrogen fuel cell vehicles or hybrid cars that have been partly operating in recent years A trolley electric vehicle that can be used as a realistic and economical means of transportation.

Automobiles, which have emerged due to the invention of internal combustion engines, are indispensable for human life, but have caused problems of energy depletion due to the main causes of environmental pollution and the enormous consumption of energy. Hydrogen fuel or internal combustion engines and hybrid vehicles combining them are being developed and used.

On the other hand, electric vehicles can be divided into three types. The first is the use of fuel cells or solar cells that generate electricity directly by heat or chemical reactions. Therefore, development of higher performance solar cells is required. The second is a car that runs on electric power stored in the battery, which is almost noiseless, vibration-free, and emits no emissions because it uses an electric motor, and does not pollute the air. While there is no need for a separate clutch or transmission, it is very easy to drive, while the battery's power storage capacity is limited, large and heavy, and the mileage per charge is short. The third method is to replenish the battery-powered car, which is a hybrid system that is equipped with a small gasoline engine and always generates electricity at constant speed and charges it with a battery. It is easy to set up gas measures.

As such, eco-friendliness is no longer mandatory for automobiles and other means of transportation, and consumers are also becoming more aware of the environment. I realized that I can't. Experts have also pointed out that carbon dioxide emissions will transform the permafrost into farmland, and that global sea levels will inevitably lead to war, and eco-friendly cars are also essential for human peace.

On the other hand, a car using a hydrogen fuel cell is too expensive compared to a general car, and a hydrogen fuel charging station has to be newly installed, which causes a lot of cost, which is a obstacle to popularization. The distance that can be driven by charging is limited, the battery is expensive and its life is short, and the driving performance of the vehicle is reduced due to the weight and volume of the battery. It is pointed out that the problem of poor wits.

In the case of eco-friendly cars, emission reduction is an absolute challenge. Efforts to reduce these emissions have led to a hybrid era, and in the early days of hybrids, the role of electricity was only 20%, but it is now up to 80%. It is expected that the era of internal combustion engines will disappear and the electric-powered electric vehicle era will come, but the issues of weight, volume, price and charging of the above-mentioned batteries still remain.

In this situation, the newly emerging method is a trolley electric vehicle, which is installed in the air on the road with electricity supply lines installed in the air, and a current collector (pantograph) is installed on the vehicle to make contact with the air lines. It is an electric car that does not have to carry a heavy battery in the vehicle by driving it.

On the other hand, the conventional trolley car has the disadvantage that the lane can not be changed freely and the line is made of a flexible conductive wire has a drawback of the complexity of the air on the road due to a number of support lines for fixing the line, curve road It is currently only used in some countries due to the difficulty of installing wires of this type to the curvature of the road.

On the other hand, a car that supplies electric power to the car by electromagnetic induction by embedding a feeder with a built-in feed coil on the floor of the road has a limitation in leveling the road surface because the distance between the feeder and the current collector is only 1 cm. In addition, when snow or rain is on the road, there is a problem that it is difficult to smoothly supply power, and there is also a disadvantage of low power transmission efficiency.

The present invention has been made to solve the above problems, an object of the present invention is a power supply for a conventional trolley-type electric vehicle relatively free from the weight problem of the vehicle due to heavy weight and volume and the high price and non-permanent battery problem By improving the device and current collector, it is possible to freely change lanes when driving, and also to simplify or omit the installation of wires at intersections, to enable smooth operation from the starting point to the destination, and even the large vehicles including small cars and trucks It is to provide an eco-friendly trolley electric vehicle that can operate with electricity.

In order to achieve the above object, the present invention is a power supply device having a rigid body wire made of a rigid body for supplying electricity to the electric vehicle running on the road on the road; A current collector for supplying electricity from the rigid wire to the electric vehicle by contacting the rigid wire of the power feeding device; An electric vehicle equipped with a rechargeable battery and an electric motor for moving electricity along the rigid wire and at the same time being continuously charged and used for moving in an area where electric power cannot be supplied from the wire; It provides a trolley electric vehicle comprising a.

In the present invention, the power feeding device is a strut which is erected at regular intervals along the road at the outer periphery of the road, a crossbar horizontally connected between the struts on the left and right sides of the road, and the height of the crossbar along the lane of the road to be adjustable It comprises a beam member that is continuously installed and a rigid wire made of a rigid body that is provided to be insulated from the beam member by an insulator insulated under the beam member and is supplied with electricity. It is installed one (one line) for each lane on the road so that when the electric vehicle changes lanes, the current collector can move from the lane before the change to the lane of the lane after the change.

Further, in the present invention, the rigid body line is continuously installed along the road, the rigid body line is not installed in the air at the intersection or the intersection of the road and the rotary point, in this area is mounted on the driving inertia of the vehicle or the vehicle It is possible to drive by the power of the rechargeable rechargeable battery, and in the area where the vehicle reenters the lane through the intersection or the rotary, the tip of the cable line is upwards so that the current collector of the electric vehicle can be guided safely to the wire. Bend.

In the present invention, the current collector is a current collector portion in contact with the rigid wire of the power supply device, the guide wing is formed on both left and right sides of the current collector to guide the current collector to the rigid wire, and the lower portion of the guide wing And a lower support means formed in the form of a universal joint positioned between the upper portion of the vehicle body, and the shape of the guide wing basically forms a wing shape in which left and right sides are inclined upward and outward, and left and right sides are respectively rear upper portions. It is desirable to form an inclined toward.

In another embodiment of the present invention, the guide wing is made of a folding type.

In addition, in the present invention, the current collector portion inside the guide wing may be manufactured in various ways such as a friction plate, a trolley shoe, a disk, a trolley roller (wheel), and the like.

In addition, the guide wing and the current collector in the present invention may be manufactured in an asymmetrical shape that can prevent the left-right symmetry or corona phenomenon.

The trolley electric vehicle according to the present invention can be operated while changing lanes freely, and can be charged while driving, and therefore, a separate charging station is not required and there is no need to stop for charging, and the electricity supply rate through the current collector is 100%. Its high power efficiency minimizes energy consumption, and the battery is used only when driving from intersections or main roads where no wires are installed to the house or garage. It can reduce the production cost, can be applied to all kinds of vehicles, not limited to small vehicles, and can be used as an electric vehicle by modifying the existing internal combustion engine cars, so that existing internal combustion engine cars, hybrid cars or hydrogen fuel electric vehicles Can be operated at a lower cost than It is expected to be able to provide environmentally friendly transportation.

Hereinafter, various embodiments of the restoring mechanism involving the horizontal rotation of the upper and lower arms and the four link will be described.

The restoring mechanism described below is a part of the configuration of the electric vehicle of the present invention, and the present invention is not limited to the restoring mechanism of the embodiments described below, and is applied to the myriad of applying the principles of the restoring mechanism described in the detailed description of the present invention. Of course, it is possible to make modifications, and the following descriptions are only limited to those parts necessary for better understanding of the present invention.

First, FIG. 17 is a sectional side view showing the center restoring mechanism N2 of the upper arm A2, and FIG. 18 is a plan view showing the operating state of the center restoring mechanism N2 shown in FIG. Restoration mechanism (N2) is the upper arm (A2) is coupled to the horizontal rotation on the lower arm (A1), the current collector 200 is separated from the power supply device (100) and at the same time (not shown sensor) The rocker (L) is screwed to the screw motor (m1) axially coupled screw (W) driven by the screw to move in the axial direction by the rotation of the screw (W), the rocker (L) is a screw housing In the inside of W1, rotation is restrained so as to be movable in the axial direction, and the screw W is fitted with a slider D freely movable along the screw W. Arm (A2) side and the hinged rod (R) is composed of a structure connected.

In the locking mechanism according to the present embodiment, when the rocker L moves toward the screw motor m1 on the drawing, the locker mechanism is in close contact with the slider D and thus suppresses the flow of the slider D, so that the horizontal rotation of the upper arm A2 is performed. When the locker L moves in the opposite direction, the slider D is freely slidable along the screw W, so that the horizontal rotation operation of the upper arm A2 is possible. That is, in the state in which the current collector on the upper end of the arm is in close contact with the rigid wire, which is the power feeding device, the screw motor m1 is driven to rotate the screw W so that the rocker L moves in the opposite direction to the screw motor m1 side. It is driven to move so that the slider (D) is free to move in the axial direction of the screw (W) to maintain a state capable of horizontal rotation of the upper arm (A2) connected to the rod (R). In addition, when the current collector 200 is spaced apart from the power supply device 100, the screw motor m1 rotates in the opposite direction to the above, and the rocker L moves toward the screw motor m1, and the slider D While being in close contact with the arm while maintaining the alignment of the front and rear of the vehicle, the slider (D) is fixed so as not to move so as not to rotate.

Cross sections of the screw housing (W1) and the rocker (L) and the slider (D) is formed in a square or polygonal shape, when formed in a circular shape may be formed a rotation preventing projection or groove on one side.

The locking mechanism according to the present embodiment may be controlled to be controlled by a separate switch provided in the vehicle or interlocked by a current collector signal of the current collector.

19 is a side cross-sectional view showing a center restoring mechanism according to another embodiment of the present invention. In this embodiment, the embodiment shown in FIG. 17 is modified without using a separate torsion spring. Compression coil spring (S ') is installed in the slider (D) to be able to flow in the housing (W1) in a state under a constant pressing force.

The embodiment shown in FIG. 19 is composed of a pure mechanical mechanism that does not require a separate power source, and the restoration mechanism by this mechanical mechanism may be variously conceived as in the embodiments described below.

20 is a plan view showing various examples of a spring-type center restoring mechanism, in which one or two springs are installed between upper and lower arms, and the upper arm is horizontally rotated from side to side, and is restored to a proper position by a spring. It is supposed to be.
