Description

An electric vehicle charging device equipped with an adjusting means in a charging charge}

Currently, charging cables for rapid and super-fast charging cables are heavy and inflexible, causing the cable to warp when moving to the charging port location of the vehicle, making it difficult to insert the charging gun into the charging port of the electric vehicle according to the direction and height of the charging port. The disabled, the elderly and women have difficulty charging. This is difficult to handle because fast and super fast charging cables use cables that flow high voltage and high current, and the cables and charging guns are heavy, so there is a risk of abrasion and damage to the cables and charging guns by falling or falling off the human body from the risk of electric shock. There is an urgent need to develop a charger to protect it.

Accordingly, the present invention proposes a device that can easily move to the left, right, and front charging port positions and directions of the vehicle by distributing the weight by hanging the charging cable on the circular rail, thereby preventing distortion of the charging cable, and Cable fatigue can be reduced.

In addition, it is possible to precisely align the location of the charging gun of the charging cable and the charging port of the electric vehicle by finely raising or lowering the charging cable with a small force by using the cable elevating control means. In particular, charging such as the disabled, the elderly and women Users with poor cable handling can conveniently use it, and by installing rails, charging cables and charging guns inside and outside the circular ring, various vehicles can be charged with charging guns of various specifications. In addition, it relates to an electric vehicle charging device provided with a charging cable adjustment means that can protect the human body from the risk of electric shock.

In general, in the case of a charging cable for super-fast charging, the charging cable itself is thick because of the high current flow, and the high heat is generated due to the large amount of heat generated.Therefore, a flow path through which the refrigerant for cooling is flowing is added inside the charging cable. . Therefore, in the case of fast and super fast charging cables, it is not easy to bend or bend the charging cable itself because it is not only thick and flexible.

In other words, when the charging cable for fast and super fast is introduced in the existing charging device, the user must directly handle the charging cable according to the charging port of the vehicle, but the charging cable for fast and super fast is not easy to handle due to its characteristics. User discomfort is great.

For this reason, it is possible for the user to park the vehicle in a direction in which the charging cable is easy to handle, but this also ignores the user's convenience, which causes another inconvenience in use.

That is, considering that the location of the charging port is different for each charging vehicle, and that the charging cable itself is not easy to handle due to the fact that the charging cable itself is thick and flexible due to the characteristics of the charging cable for rapid and super fast, the deformation of the charging cable is minimized while charging vehicle Even if the location of the charging port is different, there is an urgent need to develop a charging device that can supply and transport a charging cable to the location of the charging port and guide it to easily charge.

In addition, depending on the length of the charging cable or the height of the charging port of the vehicle, there may be a case where the coupling position between the charging gun of the charging cable and the charging port of the vehicle does not fit well. In this case, it is possible for general users, such as men, to pull or bend the charging cable with a certain force to match the connection position of the charging gun of the charging cable and the charging port of the vehicle, but for the handicapped, the elderly, and women, it is for rapid and super fast use. Due to the nature of the charging cable, it is neither easy nor easy to pull or bend the charging cable to align the position of the charging gun and the charging port.

Therefore, after transferring the charging cable for fast and super fast charging to the charging port location of the electric vehicle, even if the charging gun and charging port do not match, users such as the disabled, the elderly, and women can also finely adjust the charging cable up and down with little power to charge. There is also an urgent need to develop a charging device that can easily match the location of the gun and the charging port.

In order to explain the present invention and the operational advantages of the present invention and the object achieved by the implementation of the present invention, the following describes a preferred embodiment of the present invention and looks at it with reference.

First, terms used in the present application are only used to describe specific embodiments, and are not intended to limit the present invention, and expressions in the singular may include a plurality of expressions unless clearly differently in context. In addition, in the present application, terms such as "comprise" or "have" are intended to designate the presence of features, numbers, steps, actions, components, parts, or a combination thereof described in the specification, but one or more other It is to be understood that the presence or addition of features, numbers, steps, actions, components, parts, or combinations thereof, does not preclude in advance the possibility of being excluded.

In describing the present invention, when it is determined that a detailed description of a related known configuration or function may obscure the subject matter of the present invention, a detailed description thereof will be omitted.

First, the charging cable in the present specification not only includes a charging cable for fast and super fast. It is a concept that includes a general charging cable.

As shown in FIGS. 1 to 7, the electric vehicle charging device provided with a charging cable adjusting means according to the present invention includes a charging body 10, a rail guide 20, and a running movement along the rail guide 20. It is configured to include a cable elevating control means 40 for finely adjusting the sieve 30 and the charging cable (C) up and down.

First, as shown in FIGS. 1 to 3, the charging body 10 according to the present invention is formed to have a certain height and is installed standing on the ground, and a charging module for supplying charging electricity is built therein. This charging module is connected to the charging cable (C), the charging cable (C) is withdrawn to the outside, and the charging gun (CG) provided at its end is mounted on a coupler formed outside the charging body (10).

A control panel (not shown) is provided outside the charging body 10 so that the user can manipulate the amount of charging or payment of costs. The control panel 13 may be a touch screen or a button-type control panel for ease of use.

In addition, a mounting bracket 11 for installing the rail guide 20 is provided on the upper portion of the charging body 10 so that the rail guide 20 is coupled and installed. A cable holder 50 is formed on the upper part of the mounting bracket 11 so that the charging cable C drawn out from the charging body 10 can be mounted, and the cable holder 50 is toward the rail guide 20. Extends towards.

On the other hand, charging cables for rapid and super-fast charging are heavy and inflexible, causing the charging cable to warp when moving to the charging port location of an electric vehicle, and insert the charging gun into the charging port according to the direction and height of the charging port. This is not easy. Accordingly, there is a problem that charging is difficult for the handicapped, the elderly, and women because it is not easy to handle the charging cables for fast and super fast. In addition, fast and super fast charging cables are difficult to handle because they use cables that flow high voltage and high current, and they are heavy, so the cables and charging guns may be hit on the floor, fall off, and wear and damage, and users from the risk of electric shock. It has been required to develop a charging gun to protect the human body.

That is, in the conventional charging device, when the charging cable for rapid and super-fast charging has a heavy weight and the length of the charging cable is long, there is a fear that it may fall from the mounting position to the floor as shown in (a) of FIG. 8. If it falls to the floor of the charging cable, it may be worn or damaged due to friction with the floor. If the charging cable is damaged, there is a risk of electric shock, which can cause safety problems.

In addition, in the case of fast and super fast charging cables, not only the thickness of the charging cable is thick, but also high heat is generated due to the large amount of heat generated, so a cooling channel through which the cooling water flows inside the charging cable is built in for cooling by the cooling water. Therefore, in the case of fast and super fast charging cables, it is not easy to bend or bend the charging cable itself because it is not easy to bend or bend the charging cable itself because it is not only thick and flexible.

In other words, if a charging cable for rapid and super-fast is introduced in the existing charging device, the user must directly handle the charging cable according to the charging port of the electric vehicle, but the charging cable for rapid and super-fast is not easy to handle due to its characteristics. Therefore, the user's inconvenience is great.

For this reason, the cable cradle 50 as described above can support the charging cable C for rapid and super fast drawn out to the outside and stably supply it to the cable elevating adjustment means 40 to be described later.

Next, as shown in FIGS. 1 to 7, the rail guide 20 according to the present invention enables the charging cable C to be transferred to the supply position according to the location of the charging port of the electric vehicle.

To this end, the rail guide 20 includes a circular frame 21 for transporting the charging cable C to multiple points according to the charging position of the electric vehicle, and a circular rail 23 formed along the circular frame 21. Including.

In this case, the rail guide 20 has a circular shape, so that the traveling body 30 can move along the circular rail 23, so that it is used for rapid and super fast to the position of the charging port of the electric vehicle according to the stopping position of the electric vehicle. The charging cable (C) is transferred to increase user convenience.

This is due to the fact that the location of the charging port is different for each electric vehicle, and that the charging cable (C) itself is thick and flexible, depending on the characteristics of the charging cable (C) for rapid and super-fast charging, and it is not easy to handle. Even when the location of the charging port is different for each electric vehicle while minimizing the deformation of C), the charging cable (C) is supplied and transported to the location of the charging port by the circular rail guide 20 according to the present invention so that it can be charged easily and conveniently. I want to.

As shown in FIGS. 1 to 7, the traveling body 30 according to the present invention moves along the circular rail 23 of the rail guide 20 to carry the charging cable C.

For this, the traveling body 30 is mounted on the transfer bracket 31 on which the cable position adjusting means is mounted, and the transfer bracket 31 moves along the circular rail 23 of the rail guide 20 It consists of including a transfer roller 33 to enable.

That is, the conveying bracket 31 of the traveling body 30 is made of a plate-like member, and a pair of conveying rollers 33 are mounted on the upper and lower rear surfaces of the conveying bracket 31, respectively. In addition, the upper and lower conveying rollers 33 may move in contact with the upper and lower surfaces of the circular rail 23 of the rail guide 20.

The charging device according to the present invention is a manual charging device, which is mounted on the transport bracket 31 of the traveling body 30, more specifically, the traveling body 30, and the cable elevating control means ( 40) is integrally configured with the traveling body 30 so that when the user pulls the charging cable C to the charging port position of the electric vehicle, the transfer roller 33 of the traveling body 30 becomes the circular shape of the rail guide 20. Riding the rail 23, as shown in FIGS. 2 and 3, moves easily and easily in the horizontal direction to carry the charging cable C, so that the user can conveniently charge.

However, in this case, even if the charging cable (C) is transferred to the location where the charging gun (CG) of the electric vehicle is located, the charging of the charging cable (C) depends on the length of the charging cable (C) or the height of the charging port of the electric vehicle. There may be a case where the coupling position of the gun (CG) and the charging port of the electric vehicle does not fit well. In this case, in the case of general users, for example, men, it is possible to adjust the coupling position of the charging gun (CG) of the charging cable (C) and the charging port of the electric vehicle by pulling or bending the charging cable (C) with a certain force, but the disabled or the elderly And in the case of women, etc., it is neither easy nor easy to pull or bend the charging cable (C) to adjust the position of the charging gun (CG) and the charging port due to the characteristics of the charging cable (C) for rapid and super fast.

Therefore, in the present invention, after transferring the charging cable (C) to the charging port location of the electric vehicle, if the charging gun (CG) and the charging port do not fit, users such as the disabled, the elderly, and women can also use the charging cable (C) with little power. A cable elevating control means 40 is introduced so that the charging gun (CG) and the charging port can be aligned with each other by finely adjusting the upper and lower parts. Hereinafter, the cable elevating control means 40 will be described in more detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 7, the cable elevating control means 40 according to the present invention is mounted to the traveling body 30 so as to move and adjust the charging cable C in the vertical direction. It plays the role of matching the joint position of (CG) and the charging port.

The cable elevating control means 40 for this purpose is coupled to the traveling body 30, and the installation bracket 41 provided with the elevating rail 41a, and the charging cable C are mounted thereinto of the installation bracket 41. It comprises an elevating block 43 that moves on the elevating rail 41a, and a driving unit 45 that is mounted on the bracket to enable the elevating operation of the elevating block 43.

That is, the installation bracket 41 of the cable elevating control means 40 is mounted on the front of the transfer bracket 31 of the traveling body 30, and the elevating rail 41a in the vertical direction is constant in the front of the installation bracket 41 They are installed at intervals.

In addition, the elevating block 43 of the cable elevating control means 40 is provided with a through hole 43b formed in the vertical direction as shown in FIG. 7 and is coupled through the charging cable C, and the elevating block ( 43) A guide coupled to the elevating rail 41a is mounted on the rear, thereby enabling the elevating operation of the elevating block 43. In this case, the guide may be introduced into various types of guides such as the LM guide 43a.

In particular, the drive unit 45 of the cable elevating control means 40 moves up and down the charging cable (C) for rapid and super-fast, which is not easy to handle even with a small force even by users such as the disabled, the elderly, and women as described above. To enable fine tuning.

First, the diagrams of FIGS. 4 and 5 are the first embodiment of the driving unit 45 of the cable elevating control means 40, and the configuration and functions are as follows.

That is, the drive unit 45 is provided through the gas cylinder 45A mounted on the installation bracket 41, the rotation roll 45a mounted on the piston rod of the gas cylinder 45A, and the installation bracket 41 through the rotation roll 45a. ) And a connecting wire 45b connecting the elevating block 43 to each other.

The gas cylinder 45A of the driving unit 45 is mounted on the front side of the mounting bracket 41, and the rotary roll 45a is mounted on the upper end of the cylinder rod. In addition, a wire bracket 47 is provided on the front of the mounting bracket 41, and the connecting wire 45b of the driving unit 45 is connected to the wire bracket 47 and the elevating block 43 at both ends through the rotating roll 45a. Each is connected.

That is, the driving unit 45 raises and lowers the elevating block 43 by the gas pressure filled in the gas cylinder 45A, which is the weight of the elevating block 43 and the charging cable (C) initially. The connection wire 45b pressurizes the rotary roll 45a by weight, so that the piston rod of the gas cylinder 45A is completely inserted, and the elevating block 43 is located at the bottom of the elevating rail 41a.

In this state, when the charging gun (CG) of the charging cable (C) transferred to the charging position by the rail guide (20) and the traveling body (30) for charging and the charging port of the electric vehicle do not match, charging held by the user When the gun CG is slightly lifted, the piston rod is pulled out by the gas pressure inside the gas cylinder 45A. In addition, the connection wire 45b is pulled upward by the rotating roll 45a that rises and descends as the piston rod is withdrawn, and at this time, the lifting block 43 is elevated and positioned on the upper part of the lifting rail 41a. In this state, if the position of the charging gun (CG) and the charging port do not match, the charging gun (CG) and the charging port are charged by finely adjusting the position of the charging gun (CG) by lifting or pulling the charging gun (CG). You can match the bonding position of the sphere.

Next, the configuration and function of the second embodiment of the drive unit 45 of the cable elevating control means 40 shown in FIGS. 6 and 7 are as follows.

That is, the driving unit 45 includes a spring balancer 45B mounted on the installation bracket 41, a rotation roll 45a mounted on the installation bracket 41 and disposed above the spring balancer 45B, and a rotation roll 45a. It comprises a connection wire (45b) connecting the spring balancer (45B) and the elevating block (43) through.

The spring balancer 45B of the driving unit 45 is mounted on the rear side of the mounting bracket 41, and the rotating roll 45a is mounted on the roll bracket 46 provided in the front of the mounting bracket 41. In this case, a joint hole 48 is formed on the upper part of the installation bracket 41 so that the connection wire 45b is mounted on the rotating roll 45a, and both ends of the spring balancer 45B and the elevating through the joint hole 48 It is connected to block 43. In this case, a spring is mounted inside the spring balancer 45B, and the connection wire 45b is connected to the exposed end of the spring.

That is, the spring of the spring balancer 45B of the driving unit 45 has a property of exhibiting torsional compression and elasticity. Therefore, initially, when the connection wire 45b pulls the spring of the spring balancer 45B forward through the rotation roll 45a by the weight of the lifting block 43 and the charging cable C, the spring is compressed. Stays in the state. At this time, the elevating block 43 is located at the lower end of the elevating rail 41a.

In this state, when the charging gun (CG) of the charging cable (C) transferred to the charging position by the rail guide (20) and the traveling body (30) for charging and the charging port of the electric vehicle do not match, charging held by the user When the gun CG is slightly lifted, the pressure on the spring of the spring balancer 45B is released, and the connection wire 45b is pulled rearward by the elastic force. At this time, the elevating block 43 is pulled upward by the connection wire 45b pulled by the elastic force of the spring of the spring balancer 45B to elevate and locate the upper portion of the elevating rail 41a. In this state, if the position of the charging gun (CG) and the charging port do not match, the charging gun (CG) and the charging port are charged by finely adjusting the position of the charging gun (CG) by lifting or pulling the charging gun (CG). You can match the bonding position of the sphere.

Further, the vertical movement range of the elevating block 43 in the cable elevating control means 40 according to the present invention may be limited by the gas cylinder 45A or the spring balancer 45B of the driving unit 45. That is, the length of the piston rod lead in and out of the gas cylinder 45A, the length of the spring of the spring balancer 45B can be set.

However, in the present invention, the elevating height of the elevating block 43 is limited by the total length of the connection wire 45b. This is possible to set the length of the connection wire (45b) at the time of installation, and thus it is possible to artificially limit the elevating height of the elevating block 43, that is, the vertical movement distance. Therefore, in order to freely increase and decrease the moving distance of the elevating block 43, only the total length of the connecting wire 45b can be extended or reduced, and it is preferable that the moving range of the elevating block can be easily adjusted only with such a simple operation.

The electric vehicle charging device provided with a fast and super fast charging cable according to the present invention configured as described above is provided with a charging cable C by a rail guide 20 and a traveling body 30 as shown in FIGS. 2 and 3. It is possible to move freely in the horizontal direction.
