Description

Cabinet and charging device equipped with the same

[0001] The present invention relates to a cabinet capable of ensuring electrical stability by providing a grounding function using a door stay, and a charging device equipped with the same.

[0002] Generally, electric vehicles (EVs) have not been commercialized for a long time due to issues such as the heavy weight of the batteries mounted on the vehicle and the time required for charging, compared to gasoline or diesel cars. However, with the recent depletion of fossil fuels and environmental pollution, interest in EVs that utilize electric energy instead of fossil fuels has intensified, leading to active research and development in this area.

[0003] As a result, the adoption of electric vehicles (EVs) has been increasing recently. EVs are equipped with batteries that supply power for propulsion and store electricity within them. Therefore, to operate an EV continuously, the battery must be charged. Accordingly, infrastructure for EV charging is required, and to meet the growing demand for EVs, fixed, standing charging facilities are being installed in various locations.

[0004] Here, electrical stability and the maintenance of a long-term lifespan are key factors for establishing a stable charging infrastructure for electric vehicles. This is because charging facilities are primarily installed outdoors, such as in public buildings, park parking lots, highway rest areas, and apartment complexes.

[0005] Electric vehicle charging facilities consist of multiple electronic components, including power modules, mounted in a box-shaped case and installed in various locations as described above. At this time, securing space for installing the electric vehicle charging facilities is required.

[0006] In addition, as the adoption of electric vehicles increases, the number of times electric vehicles are charged through charging facilities per day is increasing significantly, and in this process, problems such as overloading of charging facilities and leakage of current flowing from multiple electronic components may occur.

[0007] Conventionally, to solve the above problem, a grounding method was utilized in which a grounding electrode was buried in the surrounding ground where the charging facility was installed, and the current that could leak from the charging facility was allowed to flow to the ground through a grounding connection with the grounding electrode.

[0008] However, in this case, space required for the aforementioned grounding method must be secured, and the number of necessary parts increases, which is disadvantageous in terms of cost.

[0009] Therefore, there is a need for electric vehicle charging facilities that can solve the aforementioned problems and maintain electrical stability and a long lifespan.

[0010] The present invention relates to a cabinet and a charging device equipped therewith, and more specifically, aims to provide a cabinet capable of ensuring electrical stability by providing a grounding function using a door stay and a charging device equipped therewith.

[0011] In addition, the purpose is to provide a cabinet and a charging device equipped with the same that enable simplification of the grounding method and cost reduction through a grounding method utilizing a door stay required for opening and closing the door.

[0012] In addition, the purpose is to provide a cabinet capable of stable grounding through a structure in which the link of the door stay continuously contacts the first bracket and the second bracket, and a charging device equipped with the same.

[0044] FIG. 1 is a perspective view of a charging device (100) equipped with a cabinet (300) according to an embodiment of the present invention. FIG. 2 is a front view of the charging device (100) according to an embodiment of the present invention. FIG. 3 is an enlarged view of area A of FIG. 1, illustrating the cabinet (300) according to an embodiment of the present invention.

[0045] Hereinafter, in describing a cabinet (300) and a charging device (100) equipped therewith according to an embodiment of the present invention, the left-right direction is described based on the x-axis direction, the up-down direction is described based on the y-axis direction, and the forward and rear directions are described based on the z-axis direction.

[0046] A charging device (100) according to one embodiment of the present invention may include a cabinet (300), a power module (120) housed in the cabinet (300), and a charger (150) located in the cabinet (300) and performing charging of an electric vehicle through power supplied from the power module (120). Here, the cabinet (300) serves to provide a grounding function, and more specific details regarding this will be described later.

[0047] As illustrated in FIGS. 1 and 2, the power module (120) may be located in the center of the cabinet (300). And the charging device (100) according to one embodiment of the present invention may include an output module (130) located above (in the y-axis direction) the power module (120). The output module (130) may include a DC power supply and an output terminal connected to a substrate (138). The power module (120) and the output module (130) may be electrically connected, and the output module (130) may serve to transmit power supplied from the power module (120) to a charger (150) connected to a power cable (20).

[0048] Additionally, a charging device (100) according to one embodiment of the present invention may include an input module (140). The input module (140) may be located on the lower side (y-axis direction) of the power module (120) as shown in FIGS. 1 and 2. The power module (120) and the input module (140) may be electrically connected.

[0049] Additionally, referring to FIG. 1 and FIG. 2 together, a charging device (100) according to one embodiment of the present invention may include a filter member (190) and a blower (200) housed in a cabinet (300). The case (320) of the cabinet (300) may include exhaust holes formed on both sides at positions corresponding to the filter member (190) and the blower (200), respectively. Furthermore, the efficiency of internal air circulation in the cabinet (300) can be increased through the filter member (190) and the blower (200) arranged at different heights.

[0050] Referring to FIG. 1 and FIG. 3 together, a cabinet (300) providing a grounding function according to one embodiment of the present invention may include a case (320), a door (320), a door stay (330), a conductive member (340), and a grounding cable (350). The case (320) may have a receiving space formed on the inside and may be open at the front (z-axis direction). And components including the power module (120) described above may be received on the inside of the case (320).

[0051] The door (320) is positioned at the front (z-axis direction) of the case (320), and a device capable of receiving user input regarding the charging of the electric vehicle may be provided on the front of the door (320).

[0052] In this regard, as described above, as the adoption of electric vehicles increases, the number of times electric vehicles are charged through charging facilities per day is increasing significantly. During this process, problems such as overloading of the charging facilities and leakage of current flowing from multiple electronic components may occur. Because of this, there is a risk that a user operating the input means located on the front of the aforementioned door (320) may be exposed to electric shock.

[0053] Conventionally, to solve the above problem, a grounding method was utilized in which a grounding electrode was buried in the surrounding ground where the charging facility was installed, and the current that could leak from the charging facility was allowed to flow to the ground through a grounding connection with the grounding electrode. However, in this case, the space required for the aforementioned grounding method had to be secured, and the number of necessary components increased, which was disadvantageous in terms of cost.

[0054] Accordingly, the charging device (100) according to one embodiment of the present invention aims to solve the above-mentioned problem by providing a grounding function using a door stay (330) required when opening and closing the door (320).

[0055] More specifically, a cabinet (300) according to one embodiment of the present invention may include a door stay (330) configured to connect one side of a case (320) and one side of a door (320), and to allow the door (320) to rotate in the front (z-axis direction) of the case (320). A pair of conductive members (340) may be coupled to the door stay (330). Additionally, a grounding cable (350) may be connected to the pair of conductive members (340), thereby providing a grounding function.

[0056] That is, since the charging device (100) according to one embodiment of the present invention can provide a grounding function by using the door stay (330) required when opening and closing the door (320) without using the separate grounding method described above, it is possible to structurally simplify the grounding method and reduce costs compared to the prior art.

[0057] Here, the door stay (330) may include a first bracket (331), a second bracket (332), and a link (333). The first bracket (331) is coupled to one side of the door (320) and may have a guide slit (3311) formed therein. The second bracket (332) may be coupled to one side of the case (320). And one side of the link (333) may be movably coupled along the guide slit (3311) of the first bracket (331), and the other side may be rotatably coupled to the second bracket (332).

[0058] Here, the guide slit (3311) serves to control the rotation of the door (320) by guiding the area where one side of the link (333) moves, thereby allowing the door (320) to rotate and open / close only up to a certain angle.

[0059] And a pair of conductive members (340) can be coupled to a first bracket (331) and a second bracket (332) as shown in FIG. 3, and a ground cable (350) can be connected to a pair of conductive members (340).

[0060] Here, in a cabinet (300) according to one embodiment of the present invention, the first bracket (331) and the second bracket (332) can be welded and joined to one side of the door (320) and one side of the case (320), respectively. That is, the cabinet (300) according to one embodiment of the present invention does not utilize a conventional screw fastening method for joining the door stay (330).

[0061] This is to ensure electrical stability of the door stay (330) that performs a grounding function by welding and joining the first bracket (331) and the second bracket (332) to the metal door (320) and the case (320).

[0062] In addition, the door stay (330) that performs a grounding function in the cabinet (300) according to one embodiment of the present invention may include an insulating material, thereby ensuring electrical stability as described above.

[0063] FIG. 4 is a drawing illustrating another embodiment of the cabinet (300) of the present invention. FIG. 5 is a drawing for explaining the feature in which one side of the link (333) is in contact with the first bracket (331) by the first pin member (335) in the cabinet (300) according to one embodiment of the present invention. FIG. 6 is a drawing illustrating the first pin member (335) and the second pin member (337) coupled to both ends of the link (333) in the cabinet (300) according to one embodiment of the present invention.

[0064] Referring together to FIG. 3 and FIG. 4, in a cabinet (300) according to one embodiment of the present invention, a pair of conductive members (340) may include a pair of first conductive members (341) coupled to a first bracket (331) and a link (333), and a pair of second conductive members (342) coupled to a second bracket (332) and a link (333). At this time, a grounding cable (350) may include a first grounding cable (351) connected to a pair of first conductive members (341) and a second grounding cable (352) connected to a pair of second conductive members (342).

[0065] In this case, the lengths of the first ground cable (351) and the second ground cable (352) can be reduced compared to the ground cable (350) of the structure described above through FIG. 3. By doing so, the power cable can be prevented from twisting or coming into contact with other components when the door (320) positioned at the front (z-axis direction) of the case (320) is closed, which is advantageous for ensuring electrical stability.

[0066] In addition, since the current that may leak passes from the second bracket (332) to the link (333) and from the link (333) to the first bracket (331), more stable grounding may be possible.

[0067] Accordingly, a cabinet (300) according to one embodiment of the present invention can provide a stable grounding function by combining a plurality of conductive members (340) to a door stay (330) based on the method described above and connecting a plurality of grounding cables (350) to the plurality of conductive members (340).

[0068] Referring to FIG. 5, in a cabinet (300) according to one embodiment of the present invention, the door stay (330) may include a first fastening member (334) and a first pin member (335). The first fastening member (334) may serve to fasten one side of the link (333) to the first bracket (331). The first pin member (335) may be coupled to one end of the link (333) and may come into contact with the first fastening member (334) and the first bracket (331).

[0069] This is to ensure that the link (333) moving along the guide slit (3311) of the first bracket (331) remains in continuous contact with the first bracket (331), thereby enabling stable grounding.

[0070] More specifically, the first pin member (335) may include a flat portion (3351) that contacts the first fastening member (334) and a curved portion (3352) that extends from the flat portion (3351) and contacts the first bracket (331). The first pin member (335) contacts the first fastening member (334) and the first bracket (331) and can press (P) one side of the link (333) toward the first bracket (331) by means of elastic force.

[0071] In addition, as illustrated in FIG. 6, the door stay (330) in the cabinet (300) according to one embodiment of the present invention may include a second fastening member (336) and a second pin member (337). The second fastening member (336) may serve to fasten the other side of the link (333) to the second bracket (332). The second pin member (337) may be coupled to the other end of the link (333) and may come into contact with the second fastening member (336) and the second bracket (332).

[0072] At this time, the second pin member (337) can be formed in a shape corresponding to the first pin member (335), and as described above, it can serve to enable stable grounding by ensuring that the link (333) remains in continuous contact with the second bracket (332).

[0073] Accordingly, the second pin member (337) may include a flat portion (3371) that contacts the second fastening member (336) as shown in FIG. 6, and a curved portion (3372) that extends from the flat portion (3371) and contacts the second bracket (332).

[0074] And as described above through FIG. 5, the second pin member (337) comes into contact with the second fastening member (336) and the second bracket (332), and can press the other side of the link (333) toward the second bracket (332) by means of elastic force.

[0075] Accordingly, a cabinet (300) according to one embodiment of the present invention can implement a door stay (330) capable of stably performing a grounding function by ensuring that the link (333) continuously contacts the first bracket (331) and the second bracket (332) through the first pin member (335) and the second pin member (337) coupled to both ends of the link (333).

[0076] In summary, the cabinet according to the present invention and the charging device equipped therewith can ensure electrical stability by providing a grounding function using a door stay. Furthermore, the grounding method utilizing the door stay required for opening and closing the door allows for simplification of the grounding method and cost reduction. Additionally, stable grounding is possible through a structure in which the link of the door stay remains in continuous contact with the first bracket and the second bracket.

[0077] The foregoing detailed description should not be interpreted restrictively in all respects and should be considered exemplary. The scope of the invention shall be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention are included within the scope of the invention.
