Description

TECHNICAL AREA

[0001] The present disclosure relates to a charging connection device for electric vehicles and in particular a charging connection device that is able to reduce the physical impact between a charging port of an electric vehicle and an external charging connector and to ensure a (for example, sufficient) contact area between the ports. BACKGROUND

[0002] With the increasing prevalence of electric vehicles, the demand for battery charging infrastructure is also rising. An electric vehicle stores the electrical energy supplied by an external charger in an onboard battery and is powered by this stored energy. Therefore, stability and efficiency should be considered and ensured during battery charging.

[0003] A general charging system is configured to connect an external charging connector to a charging port to supply power.

[0004] A charger can be physically coupled and electrically connected to a battery to transfer power to the battery. However, if the connection between the charging port and the charging connector is unstable in such a general charging system, power losses can occur, and there is even a risk of personal injury.

[0005] Furthermore, the physical coupling between the charging port and the charging connector leads to significant fluctuations in charging efficiency depending on the environment. The charging port and the physically coupled (e.g., to each other) charging connector are susceptible to external forces.

[0006] Furthermore, if a (for example, sufficient) electrical contact surface is not ensured, parts that are in electrical contact (for example, with each other) may overheat, or power losses may occur during fast charging or high-power supply.

[0007] Therefore, if the contact surface is not secure, the durability of the battery charging system may be affected, and the charging efficiency may also be negatively impacted.

[0008] Therefore, it would be sensible to at least create a secure contact surface. PRESENTATION OF THE INVENTION

[0009] In one embodiment, where a charging port of an electric vehicle and an external charging connector are electrically connected (for example, to each other), the present disclosure ensures a suitable (for example, sufficient) contact area between conductors.

[0010] In one embodiment, a conductive conductor of an electric vehicle charging system and a connector are designed to minimize worn, deformed, or damaged connections for charging a battery.

[0011] In one embodiment, a further aspect of the present disclosure is directed towards remedying a deteriorated charging efficiency or an interrupted charging process due to vibrations or shocks during connection and disconnection between a charging port and a charging connector, or due to an external force applied to the charging port and the charging connector during the charging process.

[0012] The present disclosure is not limited to the aspects mentioned here, and other aspects or tasks not mentioned here may arise from the following description.

[0013] An electric vehicle charging connection device according to an embodiment of the present disclosure comprises a charging connector, an inlet plug, a mounting socket, and a shock-absorbing unit. The charging connector is connected to a charger (for example, a power source) to receive electrical energy and is coupled to a charging port provided on an electric vehicle. The mounting socket is provided on the charging connector, and the inlet plug mounted on the charging port is inserted into a conductive conductor mounted in the mounting socket, such that a conductive terminal mounted on the inlet plug comes into direct contact with the mounting socket. When the inlet plug is inserted into the mounting socket, the shock-absorbing unit is deformed (for example, elastically) to bring the conductor into an electrically connected state (for example, to enable it to do so).When the inlet plug is disconnected from the mounting socket, the shock-absorbing unit ensures (for example, it allows) that the conductor returns to a standby state.

[0014] In the charging connector device for electric vehicles according to the embodiment of the present disclosure, the mounting socket can comprise a base forming part of an outer side surface of the charging connector that is coupled to the charging port while facing it, a fixed plate configured to position (for example, fix) the conductor in a position in front of the base, and a hollow cylindrical socket body with an open surface facing the base and a surface opposite the base that is provided with a socket head. The shock-absorbing unit can be a compression spring arranged between the base and the socket body.When external force is applied to the bushing body, the shock-absorbing unit can be compressed (for example, elastically) to reduce the distance between the base and the bushing body, and when the external force applied to the bushing body is no longer acting, the shock-absorbing unit can ensure (for example, enable) that the bushing body returns to its original position.

[0015] In the charging connection device for electric vehicles according to the embodiment of the present disclosure, the socket body can comprise a movable plate, which is designed as an annular rim along the outer circumference of the open surface thereof opposite the base, and a spacer which extends from the movable plate towards the base in order to limit a movement distance of the socket body towards the base.

[0016] In the charging connection device for electric vehicles according to the embodiment of the present disclosure, the socket body, the socket head, the movable plate, the spacer and the fixed plate can be provided in insulating material (for example, made of such material).

[0017] In the charging connection device for electric vehicles according to the embodiment of the present disclosure, the electrical connection state can be a state in which the socket head, while the socket body slides towards the base, approaches the conductor received in the socket body, thereby increasing the (for example, direct) contact area between the conductor and the connection entering the socket body through the socket head.

[0018] In the charging connector device for electric vehicles according to the embodiment of the present disclosure, the mounting socket can have a base forming part of an outer side surface of the charging connector that is coupled to the charging port while facing the charging port, a fixed plate configured to secure the conductor at a position in front of the base, and a hollow cylindrical socket body with an open surface facing the base and a surface opposite the base that is provided with a socket head. The shock-absorbing unit can have a first damping unit provided between the base and the socket body, and the first damping unit can dampen vibrations and shocks acting on the socket body against the base.

[0019] In the charging connector device for electric vehicles according to the embodiment of the present disclosure, the mounting socket can have a base forming part of an outer side surface of the charging connector which is coupled to the charging port while facing the charging port, a hollow cylindrical socket body which is attached in front of the base, wherein the socket body comprises an open surface facing the base and a surface opposite the base which is provided with a socket head, and a shock-absorbing end which is configured to ensure (for example, enable) that an end of the conductor is coupled to it, and to ensure (for example, enable) that the conductor enters the socket body through the open surface of the socket body and moves back and forth (for example, linearly).The shock-absorbing unit may include a second damping unit positioned between the base and the shock-absorbing end. When an external force is applied to the conductor, the second damping unit can cause (for example, allow) the shock-absorbing end to move towards the base, and when the external force applied to the conductor is removed, the second damping unit can cause (for example, allow) the shock-absorbing end to return to its original position.

[0020] A charging connection device according to at least one embodiment of the present disclosure is designed as a charging connection device provided on an electric vehicle to enable (for example, to facilitate) the attachment of a charging connector of a charger to charge a battery, and comprises a charging port, a connector, a push end, and a plug tip. The charging port is provided on the electric vehicle to enable (for example) the attachment of the charging connector to it. The connector is a conductive connector that projects (for example, linearly) forward from the charging port. The push end projects outward along the outer circumference of the lower end section of the connector, so that it has a stepped shape. The plug tip is provided at the front end of the connector.

[0021] In the charging connection device according to at least one embodiment of the present disclosure, the plug tip can be provided (for example, made) of an elastically deformable, insulating material. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present disclosure discloses a charging connection device for an electric vehicle 1.

[0029] The charging connection device for the electric vehicle 1 according to an embodiment of the present disclosure is a device for supplying a battery with energy from a power source.

[0030] The present disclosure relates to a connection device for electrically connecting a charger 2 (or a charging station), which is a power source, to a battery installed in the electric vehicle 1.

[0031] Fig. Figure 1 is a schematic view of a charging system that provides the charging connection device for the electric vehicle 1 according to an embodiment of the present disclosure.

[0032] As in Fig. As shown in Figure 1, the charging connection device according to an embodiment of the present disclosure can be mounted either on a charging port 10 provided on the electric vehicle 1 or on a charger 2 mounted at a (for example, specific) location as a power source for charging a battery.

[0033] The electric vehicle 1 is equipped with a charging port 10, through which the battery is supplied with power.

[0034] In addition, the charger 2 is equipped as a power source with a charging connector 20, which is connected to a supply cable 30.

[0035] The charging connector 20 can be disconnected from the charger 2 and move by the length of the supply cable 30.

[0036] The charging connector 20 is connected to the charging port 10 of the electric vehicle 1, which is parked near the charger 2.

[0037] The charging connection device according to the embodiment of the present disclosure can have a mounting socket 200 provided on the charging connector 20 and an inlet plug 100 provided on the charging port 10. Alternatively, the charging connection device according to the embodiment of the present disclosure can be implemented as a device that also includes both the charging connector 20 and the charging port 10, on which the mounting socket 200 and the inlet plug 100 are provided, respectively.

[0038] That is, the charging connection device according to the embodiment of the present disclosure can be implemented and embodied as the charging connector 20 on which the mounting socket 200 is provided, or as the charger 2.

[0039] Alternatively, the charging connection device according to the embodiment of the present disclosure can be implemented and designed as the charger of the electric vehicle 1, on which the inlet plug 100 is provided.

[0040] Alternatively, the charging connection device according to the embodiment of the present disclosure can be provided, for example, in the form of a charging device for electric vehicles which includes the above-mentioned components, a connection device or a charging system for electric vehicles.

[0041] Fig. Figure 2 is a cross-sectional view of the charging connection device for the electric vehicle 1 according to an embodiment of the present disclosure in order to provide a “ready state” in which the mounting socket 200 and the inlet plug 100 are separated (for example, from each other). Fig. Figure 3 is a cross-sectional view of the charging connection device for the electric vehicle 1 according to an embodiment of the present disclosure in order to provide an “electrical connection state” in which the inlet plug 100 is coupled to the mounting socket 200.

[0042] As in the Fig. 2 and Fig. As shown in Figure 3, the charging connection device according to the embodiment of the present disclosure comprises a charging port 10, a charging connector 20, an inlet plug 100, a mounting socket 200 and a shock-absorbing unit 320.

[0043] Charging port 10 is a connection for charging a battery installed in the electric vehicle 1. Charging port 10 can be mounted on the outside of the electric vehicle 1. Charging port 10 is (for example, physically) connected to the charger 2, which is a separate power source for receiving electrical energy.

[0044] The inlet connector 100 is mounted on the front of the charging port 10. The inlet connector 100 can be configured such that it protrudes straight forward from the charging port 10. In some embodiments of the present disclosure, the inlet connector 100 can be provided in multiple instances. Each inlet connector 100 is coupled and electrically connected to the mounting socket 200, which is provided on the charging connector 20.

[0045] The charging connector 20 is connected to the charger 2, which is a power source, via a supply cable 30. The charging connector 20 is connected to the charging port 10 in order to transfer power to the battery of the electric vehicle 1 via the inlet plug 100 of the charging port 10.

[0046] A portion of the outer surface of the charging connector 20, facing the charging port 10 when the charging connector 20 is coupled to the charging port 10, is designed as a base 300. The front surface of the base 300, facing the charging port 10, is provided as an actuation surface 310 (defined, for example).

[0047] The inlet connector 100 protrudes straight forward from the charging port 10. A printing end 130 may be provided on a base part of the inlet connector 100. The printing end 130 may have a stepped shape, a larger cross-sectional area than a conductive connector 110, and an external appearance that projects outwards from a base section of the connector 110.

[0048] This means that the connector 110 is designed as a linear conductor and extends (for example, linearly) forward from the pressure end 130, and an insulating plug tip 120 is connected to the distal end of the connector 110. The plug tip 120 is made of a (for example, highly) elastic material to protect the connector 110, which may have a (for example, relatively) high hardness, and can dampen an impact when the inlet plug 100 is connected to the mounting socket 200.

[0049] A conductor 710, which is conductive, may be provided to be coupled (for example, attached) relative to the base 300.

[0050] The conductor 710 can be connected to a fixed plate 700, which is mounted such that it is spaced at a predetermined distance from the actuating surface 310 of the base 300 and is held in a fixed position. One end of the conductor 710 can be connected to and fastened to the fixed plate 700.

[0051] The conductor 710 may have a coupling recess running lengthwise. The plug tip 120 and the terminal 110 of the inlet plug 100 can be received in the coupling recess in the conductor 710.

[0052] The mounting socket 200 has a socket body 400, a socket head 500, a base 300 and a conductor 710.

[0053] The socket body 400 can be a hollow cylindrical housing. The conductor 710 can be accommodated in the (for example, empty) interior of the socket body 400. The surface of the socket body 400 facing the base 300 is open, and the opposite surface of the socket body 400 is provided with a socket head 500.

[0054] The socket head 500 includes (for example, comprises) a mounting hole 510 formed in its central part. The mounting hole 510 is an entry into which the inlet plug 100 provided at the charging port 10 is inserted in such a sequence that the distal end of the inlet plug 100 enters the mounting hole 510 first.

[0055] In one embodiment, the plug tip 120, which is located at the front end of the inlet plug 100, is first guided through the mounting hole 510 in the associated mounting socket 200 and enters the socket body 400.

[0056] The plug tip 120 and the connector 110, which have penetrated the socket body 400 through the mounting hole 510, are inserted into the coupling recess in the aforementioned conductor 710.

[0057] A movable plate 600, extending outwards, can be provided along the outer circumference of the open surface of the bushing body 400. The movable plate 600 can have a ring shape formed along the outer circumference of the bushing body 400.

[0058] A spacer 610 may also be provided, which extends over a certain length from the movable plate 600 to the base 300.

[0059] The spacers 610 can be present in multiple quantities. When the bushing body 400 slides towards the base 300, the spacers 610 can restrict the distance between the actuating surface 310 of the base 300 and the movable plate 600 such that it is reduced to a predetermined distance or less.

[0060] The shock-absorbing unit 320 is provided between the bushing body 400 and the actuating surface 310 of the base 300. In one embodiment, the shock-absorbing unit 320 can be mounted between the movable plate 600, which is formed on the bushing body 400, and the actuating surface 310 of the base 300.

[0061] When the charging connector 20 and the charging port 10 are coupled (for example, to each other) and the inlet plug 100 formed at the charging port 10 penetrates the mounting socket 200, the shock-absorbing unit 320 absorbs the external force applied to the mounting socket 200.

[0062] In one embodiment, the bushing body 400, which surrounds the outer circumferences of the stationary plate 700 and the conductor 710 fixed relative to the base 300, slides towards the actuating surface 310 of the base 300, with the shock-absorbing unit 320 absorbing energy through elastic deformation. When the external force applied to the bushing body 400 ceases or is relieved, the shock-absorbing unit 320 ensures (for example, enables) that the bushing body 400 returns to its original position.

[0063] In one embodiment, the shock-absorbing unit 320 can be designed as a compression spring.

[0064] As described herein, the conductor 710 located in the socket body 400 changes its position relative to the socket body 400 when the socket body 400 is moved in the X-axis direction (for example, linearly) by the inlet plug 100 inserted into the mounting socket 200.

[0065] In the charging connection device according to the embodiment of the present disclosure, the state in which the socket body 400 is moved by the inlet plug 100 inserted into the mounting socket 200 towards the actuating surface 310 of the base 300 is provided (for example, defined) as the “electrical connection state”. In the “electrical connection state”, the inlet plug 100 can be held in a state in which it is fitted into and coupled to the mounting socket 200.

[0066] Furthermore, in the “electrical connection state”, the direct contact area between the conductive terminal 110 and the (for example, coupled to each other) conductive conductor 710 is maximized.

[0067] Conversely, when the inlet plug 100 is disconnected from the mounting socket 200, the shock-absorbing unit 320 is restored and the socket body 400 returns to its original position. As in Fig. As shown in Figure 2, the conductor 710 in the socket body 400 is spaced apart from the inner side surface of the socket head 500 by a distance between “X4” and “X5”. In the embodiment of the present disclosure, this state is provided as the “ready state” (defined, for example, as follows).

[0068] As described herein, the charging connection device operates according to the embodiment of the present disclosure (for example, systematically) to maximize the stability and efficiency of the charging system for the electric vehicle 1. The inlet plug 100 provided at the charging port 10 is coupled to the mounting socket 200 of the charging connector 20 to establish an electrical connection.

[0069] Terminal 110 and conductor 710 can be connected to each other, while a (relatively) large contact area between them is maintained by the variable internal structure of the mounting socket 200. That is, since the mounting socket 200 provided on the charging connector 20 has a variable structure, the contact area between terminal 110 and the (connected) conductor 710 is maximized, thereby ensuring (for example, providing) a stable charging efficiency during fast or ultra-fast charging.

[0070] In addition, the mounting bushing 200 has a structure that is able to absorb vibrations or external shocks acting on the bushing body 400, the bushing head 500 and the movable plate 600.

[0071] The shock-absorbing unit 320 mitigates physical shocks that occur during coupling and disconnection between the mounting socket 200 and the inlet plug 100, and ensures that the contact area between the conductive terminal 110 and the conductive conductor 710 can be adjusted (for example, variably).

[0072] The socket body (400), the socket head (500), the movable plate (600), the spacer (610), the fixed plate (700) and the plug tip (120) can be provided as insulating material (for example, made of a plastic).

[0073] Fig. 4 and Fig. Figure 5 shows cross-sectional views of a charging connection device for an electric vehicle 1a according to another embodiment of the present disclosure.

[0074] As in the Fig. 4 and Fig. As shown in Figure 5, the charging connection device for the electric vehicle 1a according to another embodiment of the present disclosure can comprise a first damping unit 330 as a shock-absorbing unit 320a.

[0075] The first damping unit 330 can be designed as a hydraulic or pneumatic cylinder. A plurality of first damping units 330 can be mounted between an actuating surface 310a of a base 300a and a movable plate 600a, which is formed along the circumference of an open surface of a bushing body 400a.

[0076] As shown, the first damping unit 330 absorbs and mitigates the external force applied to a bushing body 400a in the -X-axis direction due to the entry of an inlet plug 100a, and ensures (for example, enables) that the bushing body 400a moves without shocks in the direction of the actuating surface 310a of the base 300a.

[0077] In another embodiment, a conductor 710a is fixed relative to the base 300a and the socket body 400a, which receives the conductor 710a, is displaceable in the ± X-axis directions, for example in the longitudinal direction of the conductor 710a.

[0078] Fig. 6 and Fig. Figure 7 are cross-sectional views of a charging connection device for an electric vehicle 1b according to a further embodiment of the present disclosure.

[0079] As in the Fig. 6 and Fig.As shown in Figure 7, in a further embodiment of the present disclosure, a socket body 400b, a movable plate 600b, and a socket head 500b can be attached relative to a base 300b in the charging connection device. Furthermore, one end of a conductor 710b is connected to a shock-absorbing end 702 made of an insulating material. The conductor 710b coupled to the shock-absorbing end 702 is movable back and forth along a straight section in the ± X-axis directions within the socket body 400b, together with the movement of the shock-absorbing end 702.

[0080] In a further embodiment of the present disclosure, an actuating surface 310b of the base 300b and the shock-absorbing end 702 can be connected to each other via a plurality of second damping units 340. Each of the second damping units 340 can be designed as a shock absorber in which a damper and a spring are coupled (for example, to each other).

[0081] In the charging connection device according to a further embodiment of the present disclosure, a plug tip 120b and a terminal 110b exert an external force on the conductor 710b in the -X-axis direction as they penetrate a coupling recess formed in the conductor 710b when an inlet plug 100b is inserted through a mounting hole 510b into the socket body 400b. The conductor 710b can be coupled to the plug tip 120b and the terminal 110b, which penetrate the coupling recess, as they move (for example, gently) towards the base 300b due to the second damping units 340, which are connected to the shock-absorbing end 702 and absorb the external force and vibration.

[0082] As described herein, the charging connection device according to the present disclosure can be designed such that the coupling between the charging port 10 and the charging connector 20 is optimized and can create a connection environment that enables fast charging and ultra-fast charging (for example, enables).

[0083] According to the present disclosure, due to the structural features of an inlet plug mounted on a charging port and a mounting socket provided on a charging connector, a more secure physical coupling between the charging port and the charging connector can be achieved, thereby enabling stable current transmission and improved charging efficiency.

[0084] According to the present disclosure, when the charging connector is coupled to the charging port, it is deformed in such a way that the contact area between a conductive terminal and a conductive conductor increases, thereby preventing heat generation caused by electrically connected parts and reducing the possibility of damage or deformation of the connector.

[0085] According to the present disclosure, external shocks or vibrations can be (for example, effectively) distributed and absorbed by a shock-absorbing unit provided between the charging port and the charging connector, a connection cannot be (for example, easily) worn even by repeated coupling and disconnection between the charging port and the charging connector, and the durability of the charging connection parts can be improved.

[0087] The embodiments of the present disclosure have been described above with reference to the accompanying drawings. However, these embodiments are proposed only for illustrative purposes, and the present disclosure is not limited to the embodiments described above and the accompanying drawings.
