Field of the Invention The present invention relates to a cable control apparatus for charging an electric vehicle and a canopy for an electric vehicle charger having an atmospheric booth, A cable control device for charging an electric vehicle and an atmospheric booth capable of preventing slack of the charging cable connecting the electric power supply unit and monitoring the charging state while the user is resting in a separate space while charging the electric energy To a canopy for an electric vehicle charger.

Generally, a gasoline engine using a fossil fuel or an automobile equipped with a diesel engine burns gasoline or diesel to obtain a driving force, so nitrogen oxides including particulates are released to the atmosphere while fossil fuels are burned.

These substances are released into the atmosphere and become the main cause of air pollution. Such air pollution is known to generate fine dust.

As the fossil-fueled automobiles are used to generate fine dust, environmentally friendly vehicles that do not use fossil fuels are being researched and developed.

Examples of environmentally friendly vehicles include hybrid vehicles, electric vehicles and fuel cell vehicles.

Among these automobiles, electric vehicles do not emit any pollutants during the operation of automobiles, and the driving noise of the engine is small.

Electric vehicles use electric energy as driving energy, so they are equipped with a driving battery capable of storing and storing electric energy from the outside.

A driving motor is driven by using the electric energy charged in the driving battery, and a driving force is transmitted to the wheel through the transmission to drive the vehicle.

When an electric vehicle uses all the electric energy stored in the driving battery, there is no energy to drive the driving motor, so that the electric vehicle can not travel. Therefore, charging means capable of charging electric energy is required.

In order to charge the electric car with electric energy, a system which can use electricity of each household is equipped, and a charging device is installed in a parking lot of a public house, a road side or other necessary place.

Any charging means requires a charging gun connected to a charger unit which is a power supply unit, and a charging cable for connecting the charging gun and the charger unit is required.

The charging cable has an elongated state when charging electric energy into an electric vehicle, and when the charging is completed, the elongated charging cable must be returned to its original state.

Korean Patent No. 10-1372784 discloses a device for winding and winding a charging cable from a bobbin by winding a charging cable around a bobbin and rotating the bobbin using a motor.

However, there are a fast charging method and a full charging method in which an electric vehicle is charged with electric energy. In any method, a charging gun connected to a charging cable to be used and a charging connector to which the charging gun is connected include a plurality of pins Structure. Charging cable used in rapid charging system becomes thicker.

Therefore, the charging cable is connected to each of the pins, and a plurality of independent electric wires for supplying electric energy are used, and these electric wires are integrally covered to constitute a charging cable.

If an external force is applied to the charging cable, such as charging a charging cable having such a structure to a bobbin, the charging cable may be damaged. In the case of the quick charging cable, the charging cable is too thick to be wound around the bobbin. In order to wind such a thick charging cable around the bobbin, it is practically impossible to increase the diameter of the bobbin.

In addition, winding and unplugging the charging cable to the bobbin may damage the charging cable, and damage to the charging cable can cause unexpected safety hazards, including electric shock.

In addition, the charging cable is exposed to the outside and is continuously exposed to the sunlight, thus contributing to a shortening of the life span.

Further, there is an inconvenience that the user must continuously check the charging state around the electric vehicle while charging the electric vehicle with the charging cable.

Depending on the number of the charging cables 10 provided with the charging gun 8, one or more charging cable suspending means may be provided.

Since the pulling string 32 suspends the charging cable 10, it is preferable that the pulling string 32 has a strength not to be increased by the weight of the charging cable 10.

Since the first pulley 28 is rotated in the releasing direction by the weight of the charging cable 10 in a state in which the driving motor 26 is not driven substantially in this embodiment, And the elastic means (34) for rotating the first pulley (28) in the unwinding direction only when a certain force or more acts on the pulling string (32).

The elastic means 34 provided by this embodiment is connected to the second pulley 30 to restrain the free pulley 28 from rotating in the free pulley 28 together with the drive shaft 27 and at the same time, So that the first pulley 28 can be rotated in the unwinding direction.

The elastic means 34 includes a case 36 fixedly installed inside the housing 18 as shown in FIGS.

The case 36 has a substantially rectangular parallelepiped shape and is provided with a shaft 38 passing through the inner space portion thereof.

A spring 40 is provided on the outside of the shaft 38 and a reel 42 is provided on the outside of the spring 40.

In this embodiment, the inner end of the spring 40 is fixed to the shaft 38 and the outer end of the spring 40 is fixed to the reel 42.

With this configuration, the reel 42 will rotate only when an external force greater than the elastic force of the spring 40 is applied.

The control rod 44 is wound on the outer periphery of the reel 42 and the other end of the control rod 44 is wound on the second pulley 30 so that the reel 42 and the second pulley 30 So that they have an interlocking relationship.

Further, at one end of the shaft 38, an elastic force adjusting means for adjusting the elastic force of the spring 40 may be provided.

The elastic force of the spring 40 can be adjusted by forming a groove 39 in the shaft 38 and inserting a separate tool into the groove 39 and rotating the shaft.

The wheel 48 has a plurality of hooks 52 on the outer circumferential surface thereof and the stopper 50 forms a hook 54 on which the hooks 52 can be hooked.

In the canopy for an electric vehicle charger according to the embodiment of the present invention, when the electric vehicle is not charged, the charging gun 8 is placed in the charging gun mounting portion 56 as shown in Fig. 1, The pulling string 32 is wound on the first pulley 28 so that the substantially middle portion of the charging cable 10 is suspended on the pulling string 32. [

In this state, the charging cable 10 is not hanged on the ground because the charging cable 10 is suspended from the pulling string 32.

In order to charge the electric energy in such a non-charged state, the charging gun 8 is separated from the charging gun mounting portion 56, the charging gun 8 is connected to a charging socket (not shown) of the electric vehicle, 4 may be operated by operating the operation panel.

At this time, the restoring force of the spring 40 is added to the rotation direction of the second pulley 30 while the spring 40 of the elastic means 34 is unwound from the original state, The elastic force of the elastic spring 34 of the elastic means 34 can be adjusted by the self weight of the charging cable 10 when the driving of the driving motor 26 is stopped while the charging cable 10 is in the state of Fig. It is possible to prevent striking.

That is, the state shown in FIG. 2 can be maintained in a state in which the drive of the drive motor 26 is stopped when no electric energy is charged.

The elastic force of the spring 40 of the elastic means 34 is transmitted to the drive shaft 27 through the control rod 44 to restrict the rotation of the first pulley 28, This is because the pulling string 32 is not released.

The elastic means 34 adjusts the elastic force of the spring 40 so as to facilitate the use of the spring 40. In this embodiment, the elastic force of the spring 40 is adjusted by rotating the shaft 38 have.

That is, when the shaft 38 is rotated by inserting a driver or other tool into the groove 39 formed in the shaft 38, the inner end of the spring 40 is fixed to the shaft 38, The spring 40 will be wound along the direction of rotation of the shaft 38, and the elastic force will be increased or the elastic force will be reduced while being released.

When the elastic force is adjusted, the hook 38 of the stopper 50 is hooked on the stopper 52 of the wheel 48, so that the axis 38 is restrained, so that the elasticity of the spring 40 can be maintained .

The adjustment of the elastic force of the elastic means 34 not only prevents the charging cable 10 from being stuck in the state of FIG. 2 but also gives a certain degree of resistance when pulled into the state of FIG. 8, It can prevent coming.

In particular, when the charging cable 10 is suspended and stored as shown in FIG. 2, the charging cable is folded several times, so that the charging cable 10 can be formed longer.
