Description

[Technical Field]

[0001] The present invention relates to a vehicle lid opening and closing device that is attached to the body of a vehicle such as an automobile, covers a charging port, and has an openable and closable lid. [Background technology]

[0002] To charge the battery of an electric vehicle or plug-in hybrid vehicle (PHEV), open the lid and insert the charging connector into a quick charge port or a normal charge port.

[0003] For example, Patent Document 1 discloses a charging port device mounted on a vehicle. Figure 3 shows the technology disclosed in Patent Document 1, in which a charging port device 110 includes a port storage recess 102 formed in the surface of the vehicle body (left front fender 101), a charging port 200 provided in the port storage recess 102, a lid 111 attached to the vehicle body and covering the port storage recess 102, a lid hinge 114 attached to the vehicle body and holding the lid 111 in an openable and closable state, and a latch 400 provided on the opposite side of the lid hinge 114 from the charging port 200 in the port storage recess 102 and holding the lid 111 in a closed state.

[0004] The lid 111 is composed of a metal outer panel 112 and a resin part 113 attached to the inside of the outer panel 112. A lid hinge 114 is formed in the resin part 113 and is arranged on the front side of the port accommodating recess 102. The lid hinge 114 is formed at the end of an extending portion of the resin part 113 and is attached to the interior front of the port accommodating recess 102 so as to be able to swing. A catch 115 that engages with the latch 400 is formed in the resin part 113.

[0005] A charging port 200 that complies with the CHAdeMO charging standard is provided in the center of the port housing recess 102. A resin cap 300 that covers the charging port 200 is also provided. The cap 300 is attached to the front of the charging port 200 via a cap hinge 310 so that it can be opened and closed. A lock 320 that holds the cap 300 closed is also provided on the rear side of the charging port 200. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 7173431 Summary of the Invention [Problem to be solved by the invention]

[0007] Incidentally, the resin cap 300 that covers the charging port 200 needs to be opened at an angle exceeding 90 degrees relative to the upper surface of the charging port 200 so as not to interfere with the insertion of the charging connector. Patent Document 1 does not describe a method for opening and closing the lid 111 and the cap 300, but when the cap 300 is opened and closed manually, the cap 300 hits the resin part 113 when the lid 111 is closed with the cap 300 open.

[0008] As described above, because the cap 300 is opened at an angle exceeding 90 degrees relative to the top surface of the charging port 200, depending on the angle at which the cap 300 and the resin part 113 of the lid 111 come into contact, the cap 300 may receive a force in a direction that causes it to open further after it comes into contact with the resin part 113. In this case, the lid 111 cannot be closed. Furthermore, if an attempt is made to close the lid 111 in this state, the cap 300, the cap hinge 310, the connection between the cap 300 and the charging port 200, and the resin part 113 may be deformed or damaged.

[0009] Therefore, the present invention provides a vehicle lid opening and closing device that can close the cap and lid simultaneously even when the cap is open or the lid is closed after the cap has been forgotten to be closed, and that can prevent the cap, etc. from being deformed or damaged. [Means for solving the problem]

[0010] In order to solve the above problem, the present invention of claim 1 is a lid opening / closing device for a vehicle, comprising: a lid that opens and closes the exterior side of a charging port provided in an opening of a recess formed in a part of the vehicle body; a lid mounting member having a lid mounting portion attached to the lid and an arm that extends in a curved manner from the lid mounting portion; and a box that engages with the vicinity of the end of the arm opposite the lid mounting portion to rotatably hold the arm, has an opening formed therein for accommodating the charging port, and is mounted to the opening in the vehicle body, wherein an inner lid that is journaled on the charging port or box and enables the exterior side of the charging port to be opened and closed is attached near the opening of the charging port or box, and the lid mounting portion of the lid mounting member is formed with an inner lid guide portion that includes a recessed shape that abuts against the inner lid when the lid is moved in its closing direction to close the inner lid.

[0011] In the present invention of claim 1, an inner lid is attached near the opening of the charging port or box, and is journaled to the charging port or box, allowing the charging port to be opened and closed on the vehicle exterior side. The lid attachment portion of the lid attachment member is formed with an inner lid guide portion that includes a recessed shape that abuts against the inner lid and closes the inner lid when the lid is moved in its closing direction. Therefore, even when the inner lid (cap in Patent Document 1) is open and an operation to close the lid is performed, the inner lid abuts against the inner lid guide portion, and the inner lid can be moved in the closing direction.

[0012] As a result, even if the inner lid is open, for example, when the operator forgets to close the inner lid, the lid and the inner lid can be closed. In other words, the charger does not need to close the inner lid, but only needs to close the lid. This prevents deformation or damage to the inner lid, the charging port of the inner lid, the connection portion with the box, and the lid attachment portion of the lid.

[0013] The present invention of claim 2 is a vehicle lid opening and closing device according to the invention of claim 1, wherein the inner lid is formed with a protruding piece that protrudes in the lid direction and abuts against the inner lid guide portion, and the inner lid guide portion follows the trajectory of the tip of the protruding piece.

[0014] According to the present invention of claim 2, the inner lid is formed with a protruding piece that protrudes toward the lid and abuts against the inner lid guide portion. Therefore, when manually opening the inner lid, the inner lid can be easily opened by hooking a finger on the protruding piece. Furthermore, since the inner lid guide portion follows the path of the tip of the protruding piece, the lid and the inner lid can be closed even when the inner lid is open, for example, when the lid is closed after forgetting to close it. Furthermore, deformation or damage to the inner lid, the connection portion of the inner lid with the charging port or box, and the lid mounting portion of the lid can be prevented.

[0015] The present invention of claim 3 is a lid opening and closing device for a vehicle, in the invention of claim 2, wherein the protruding piece has a protruding portion protruding from the inner lid toward the lid and a flat portion extending from the tip portion of the protruding portion approximately parallel to the upper surface of the charging port and in a direction away from the upper surface, and the inner lid guide portion has a first recess, a second recess that accommodates the protruding piece, and an intermediate connecting portion that connects the first recess and the second recess, and in the process of the lid reaching a fully closed state, at least one of the first recess and the intermediate connecting portion abuts the flat portion and the inner lid, and presses the inner lid in the direction of closing.

[0016] In the present invention of claim 3, the protruding piece has a protruding portion that protrudes from the inner lid toward the lid, and a flat portion that extends from the tip portion of the protruding portion approximately parallel to the charging port portion and in a direction away from the charging port portion, so that when manually opening the inner lid, the inner lid can be easily opened by hooking a finger on the flat portion of the protruding piece.

[0017] In addition, the inner lid guide portion has a first recess, a second recess that accommodates the protruding piece, and an intermediate connecting portion that connects the first recess and the second recess, and in the process of the lid reaching a fully closed state, at least one of the first recess and the intermediate connecting portion abuts against the flat portion of the first recess and the inner lid of the intermediate connecting portion, pressing the inner lid in the direction of closing, so that the inner lid can also be closed reliably.

[0018] The present invention of claim 4 is the vehicle lid opening and closing device of claims 1 to 3, wherein a frame portion that abuts against a wall surface of the charge port is formed on the charge port side of the inner lid.

[0019] According to the present invention, a frame that abuts against the wall of the charge port is formed on the inner lid on the side facing the charge port, and when the inner lid is closed, the frame of the inner lid abuts against the wall of the charge port, fixing the inner lid in place. As a result, repeated contact and separation between the inner lid and the top surface of the charge port due to, for example, road surface or vehicle vibrations while driving can be prevented, preventing the generation of abnormal noise. [Effects of the Invention]

[0020] A lid opening and closing device for a vehicle includes: a lid that opens and closes the exterior side of a charging port provided in an opening of a recess formed in a part of the vehicle body; a lid mounting member having a lid mounting portion attached to the lid and an arm that curves and extends from the lid mounting portion; and a box that engages with the vicinity of the end of the arm opposite the lid mounting portion, rotatably holding the arm, and has an opening formed therein for accommodating the charging port, and is attached to the vehicle body. An inner lid that is journaled on the charging port or box and allows the exterior side of the charging port to be opened and closed is attached near the opening of the charging port or box, and the lid mounting portion of the lid is formed with an inner lid guide portion that includes a recessed shape that abuts against the inner lid and closes the inner lid when the lid is moved in its closing direction, so that the inner lid abuts against the inner lid guide portion and can be moved in the closing direction.

[0021] As a result, the lid can be closed even when the inner lid guide is open, i.e., when the lid is closed while the inner lid guide is forgotten to be closed, and deformation or damage to the inner lid, the charging port of the inner lid, the connection portion with the box, and the lid mounting portion of the lid can be prevented. [Brief explanation of the drawings]

[0022] [Figure 1] 1 is a perspective view of a vehicle lid opening and closing device in a state where a lid and an inner lid are both open (fully open). [Figure 2] 3A and 3B are a perspective view and a cross-sectional view illustrating the relationship between the inner lid and the inner lid guide portion of the vehicle lid opening and closing device during the process of closing the lid; [Figure 3] FIG. 1 is a perspective view of a conventional charging port device with both the lid and the cap open (Patent Document 1). DETAILED DESCRIPTION OF THE INVENTION

[0023] An embodiment of the present invention will be described with reference to Figures 1 and 2. A vehicle lid opening and closing device 10 of this embodiment is provided on a left front fender 2 of a vehicle body 1. Note that the present invention is not limited to the left front fender 2, and is also applicable to cases where the device is provided on other locations such as a right front fender or left and right rear fenders.

[0024] FIG. 1 is a perspective view of a vehicle lid opening and closing device with both the lid and the inner lid open (fully open). In FIG. 1, the lid 20 and the inner lid 60 open and close in the same direction. As shown in FIG. 1, a vehicle lid opening and closing device 10 is provided in an opening 4 of a recess 3 formed in the surface of a left front fender 2. The vehicle lid opening and closing device 10 includes a resin lid 20 formed in the shape of the opening 4 of the recess 3 and used to open and close the charging port 50 on the vehicle exterior side, a lid mounting member 30 mounted on the lid 20, and a box 40 that houses the end of the lid mounting member 30 opposite the lid 20. The lid 20 may be made of metal.

[0025] (Charging port 50) Charging port 50 used in this embodiment complies with the charging standard CCS (Combined Charging System), and includes an AC charging port 51 located on the upper side of the vehicle body, a DC charging port 52 located on the lower side, and an upper surface portion 53 that spans AC charging port 51 and DC charging port 52. AC charging port 51 is compatible with "normal charging" at home, and DC charging port 52 is compatible with "rapid charging" at facilities such as charging stands.

[0026] The charging port 50 includes an inner lid 60 that closes the vehicle exterior side of the DC charging port 52. The inner lid 60 is pivotally supported by an inner lid attachment portion 54 formed on an upper surface 53 of the charging port 50 via a needle-shaped metal shaft 55 and is held rotatably. Although not shown, the inner lid attachment portion 54 has a structure in which a metal plate bent at an acute angle is attached to the upper surface 53 of the charging port 50 as a stopper to prevent the inner lid 60 from opening too far, and the stopper abuts against an inner lid rotation portion 61 of the inner lid 60. Note that the structure for preventing the inner lid 60 from opening too far is not limited to the metal plate described above. The shape of the inner lid rotation portion 61 of the inner lid 60 may be, for example, a square-shaped cam, or a combination of a metal plate and a cam, or other structures may also be applied.

[0027] (Inner lid 60) The inner lid 60 includes a flat-plate-shaped cover portion 63 that is located on the vehicle exterior side of the upper surface 53 of the charge port 50 when the inner lid 60 is closed, a frame portion 64 that is connected to the cover portion 63 and can be inserted into the DC charge port 52 of the charge port 50, a protruding piece 65 that protrudes from the cover portion 63 toward the lid, and an inner lid rotating portion 61 that extends from an end located substantially opposite the protruding piece 65 and has a hole 62 formed at its tip. In this embodiment, as shown in FIG. 2 , a portion of the cover portion 63 that corresponds to the inner circumferential portion of the frame portion 64 is recessed toward the charge port 50. The cover portion 63 may also have a flat-plate shape.

[0028] When the inner lid 60 is closed, the frame portion 64 abuts against the wall surface 56 of the DC charging port 52. However, the frame portion 64 does not have to abut against the wall surface 56 of the DC charging port 52 when the inner lid 60 is closed.

[0029] The inner lid rotating portion 61 is attached to the inner lid mounting portion 54 of the charging port 50, and the shaft 55 passes through a hole 62 formed in the inner lid rotating portion 61 and is attached to the charging port 50, so that the inner lid 60 is rotatably held on the upper surface portion 53 of the charging port 50.

[0030] During AC charging, the inner lid 60 is closed and a charging connector (not shown) is inserted into the AC charging port 51. However, a portion of the upper side of the lid portion 63 of the inner lid 60 on the vehicle body side is cut out so that it does not come into contact with the charging connector for AC charging.

[0031] Meanwhile, the protruding piece 65 of the inner lid 60 includes a protruding portion 66 that protrudes obliquely from the end of the inner lid 60 on the AC charging port 51 side toward the lid 20 and in a direction away from the lid portion 63, and a flat plate portion 67 that extends from the tip of the protruding portion 66 substantially parallel to the lid portion 63 and in a direction away from the lid portion 63. The flat plate portion 67 is triangular, and one side thereof, a tip edge portion 68, abuts against an inner lid guide portion 33 formed on the lid mounting portion 31 of the lid mounting member 30, which will be described later.

[0032] (Lid mounting member 30) The lid mounting member 30 is made of resin and has a lid mounting portion 31 that is attached to the lid 20, and an arc-shaped arm 32 that extends in a large curve from the lid mounting portion 31. The lid mounting member 30 also has a catch 37 that engages with a latch 70 attached to the box 40 (described later) when the lid 20 is closed, and a rod-shaped detection piece 38 that detects whether the lid 20 is open or closed.

[0033] The lid mounting portion 31 is also formed with an inner lid guide portion 33 that comes into contact with the leading edge portion 68 of the flat plate portion 67 of the inner lid 60 when the lid 20 is moved in the closing direction. The inner lid guide portion 33 will be described in detail later. If the lid 20 is made of resin, the lid 20 and the lid mounting member 30 may be integrally molded.

[0034] In addition, the lid mounting portion 31 has a seal portion 39 that is approximately the same shape as the opening 41 for accommodating the charging port 50 of the box 40 described later, and that elastically contacts the vicinity of the opening 41 of the box 40 when the lid 20 is closed.

[0035] Incidentally, the lid mounting portion 31, excluding the inner lid guide portion 33, is versatile and can be applied to energy sources other than electric vehicles, such as fuels such as gasoline and hydrogen, so the portion including the inner lid guide portion 33 may be formed as a separate member and attached integrally to the lid mounting portion 31. In this embodiment, the portion including the inner lid guide portion 33 and the seal portion 39 is formed as a separate member and attached to the lid mounting portion 31. Therefore, in this embodiment, the lid mounting portion 31 is an integral unit to which the inner lid guide portion 33 and the seal portion 39 are attached.

[0036] (Box 40) The box 40 is made of resin and is attached to the opening 4 of the recess 3 of the vehicle body 1. The box 40 engages with the vicinity of the end of the arm 32 opposite the lid mounting portion 31 side, and rotatably holds the lid 20. The axis X indicated by the dashed dotted line is the center of rotation of the arm 32, and as is clear from FIG. 1 , the end of the arm 32 opposite the lid mounting portion 31 side is housed in the box 40 located inside the left front fender 2 forward of the opening 4 of the recess 3.

[0037] An opening 41 for accommodating the charge port 50 is formed in the box 40. A latch 70 that engages with the catch 37 of the lid mounting member 30 is attached to the rear side of the charge port 50 on the vehicle body 1. The latch 70 is a so-called push latch, and when the latch 70 is pressed from above the closed lid 20, the lid 20 rises to a half-open, unlocked state, and the lid 20 can be opened by pulling the edge of the lid 20. Conversely, when the lid 20 is pressed against the latch 70, the lid 20 is closed, and the closed state is maintained by the latch 70, and the lid 20 is locked.

[0038] Furthermore, an elongated hole 42 is formed above the latch 70. This elongated hole 42 is formed to correspond to the detection piece 38 of the lid 20. A sensor having a light-emitting element and a light-receiving element facing each other (not shown) is attached to the back of the elongated hole 42. When the lid 20 is closed, the detection piece 38 is inserted into the elongated hole 42, and the detection piece 38 is positioned between the light-emitting element and the light-receiving element, thereby confirming that the lid 20 is closed.

[0039] When the lid 20 is closed, the seal portion 39 of the lid mounting member 30 elastically contacts the periphery of the opening 41 of the box 40 to seal the gap between the lid mounting member 30 and the box 40 .

[0040] (Inner lid guide part 33) 2 is a perspective view of the vehicle lid opening and closing device 10 when the lid 20 is being closed, and a cross-sectional view illustrating the relationship between the inner lid 60 and the inner lid guide portion 33. The cross-sectional view is drawn in the approximate center of Fig. 2 and depicts the lid 20, the lid mounting portion 31, the inner lid guide portion 33 including the seal portion 39, and the inner lid 60. The upper side of the vehicle from the cross-section is indicated by a two-dot chain line to make the cross-section easier to see.

[0041] The inner lid guide portion 33 is formed along the trajectory of the tip edge portion 68 of the flat portion 67 of the protruding piece 65 of the inner lid 60, and is composed of a first recess 34, an intermediate flat portion 35 and a second recess 36 from the arm 32 side.

[0042] The first recess 34 is formed so that when the lid 20 is moved in its closing direction, the tip edge portion 68 of the flat portion 67 of the inner lid 60 abuts within the first recess 34, and at the abutment portion between the tip edge portion 68 and the first recess 34, the inclination of the first recess 34 is on the outside of the vehicle in the tangent direction of the tip edge portion 68 in the direction of closing the inner lid 60, i.e., toward the rear of the vehicle, and the tip edge portion 68 of the flat portion 67 abuts against the first recess 34, so that a force always acts on the tip edge portion 68 in the closing direction.

[0043] The intermediate flat portion 35 is connected to the first recess 34 and is formed in the direction of the catch 37 from the first recess 34. The second recess 36 has an inclined surface that protrudes slightly toward the charging port 50 from the first recess 34. The intermediate flat portion 35 may be shared with a surface of the lid mounting portion 31 other than the inner lid guide portion 33.

[0044] The second recess 36 is connected to the intermediate flat portion 35 and is formed to be able to accommodate the protruding piece 65 (the protruding portion 66 and the flat portion 67) of the inner lid 60. The depth of the second recess 36 is the same as the height of the protruding piece 65 of the inner lid 60.

[0045] At least one of the second recess 36 and the intermediate flat portion 35 is formed so that when the lid 20 is moved in the closing direction, the second recess 36 abuts against the flat portion 67 of the protruding piece 65 of the inner lid 60, and the intermediate flat portion 35 abuts against the cover portion 63 of the inner lid 60. In this embodiment, the second recess 36 abuts against the flat portion 67 of the protruding piece 65 of the inner lid 60.

[0046] The positional relationship between the lid 20 and the inner lid 60 when the lid 20 is in the process of going from fully open to fully closed will be described below. First, the case where the lid 20 is opened will be described. To fully open the lid 20, the closed lid 20 is pushed from the outside of the vehicle body 1, which pushes the latch 70, disengaging the latch 70 from the catch 37, causing the lid 20 to rise up and enter a half-open, unlocked state. Then, by pulling on the edge of the lid 20, the lid 20 can be opened to the fully open position. At this time, the inner lid 60 is closed.

[0047] Next, the inner lid 60 can be opened by hooking a finger on the flat portion 67 of the protruding piece 65 of the inner lid 60 and pulling it. Because a stopper for the inner lid 60 is attached to the charging port 50, the inner lid 60 can be opened to the fully open position without going beyond the fully open position. After that, the charging connector is inserted to start charging.

[0048] Next, we will explain how to close the lid 20. This operation involves pulling out the charging connector after charging is completed and manually closing the lid 20. As shown in Figure 2, the lid attachment portion 31 is formed with an inner lid guide portion 33, and when the lid 20 moves in the closing direction, the tip edge portion 68 of the flat portion 67 of the protruding piece 65 of the inner lid 60 first enters the first recess 34 and abuts against it.

[0049] When a force is further applied to the lid 20 in the closing direction, the first recess 34 comes into contact with the leading edge 68 of the flat portion 67 of the inner lid 60 within the first recess 34 as the lid 20 is moved in the closing direction, and since the cross section is formed in a shape that always acts on the inner lid 60 in the closing direction while the leading edge 68 of the flat portion 67 and the first recess 34 are in contact, the inner lid 60 moves in the closing direction together with the lid 20. Figure 2 shows the time when the leading edge 68 of the flat portion 67 has reached the vicinity of the end of the first recess 34.

[0050] When a force is further applied to the lid 20 in the closing direction, the tip edge 68 of the flat portion 67 moves from the first recess 34 to the intermediate flat portion 35, and the inner lid 60 continues to move together with the lid 20 in the closing direction.

[0051] When further force is applied to the lid 20 in the closing direction, the tip edge 68 of the flat plate portion 67 moves from the intermediate flat portion 35 to the second recess 36, and the inner lid 60 continues to move in the closing direction together with the lid 20. The flat plate portion 67 then abuts against the upper surface of the second recess 36. Immediately after the flat plate portion 67 abuts against the second recess 36, the lid 20 moves to a position that is approximately flush with the vehicle body 1. At this time, the frame portion 64 of the inner lid 60 is inserted and abutting against the wall surface 56 of the DC charging port 52, but the inner lid 60 is not completely closed.

[0052] When the lid 20 is further pressed, the push-latch latch 70 presses the lid 20 slightly toward the interior of the vehicle from the surface of the vehicle body 1, and the second recess 36 continues to press the flat plate portion 67 toward the interior of the vehicle, causing the cover portion 63 to abut against and be fixed to the upper surface portion 53 of the charging port 50, and the inner lid 60 is in the fully closed position.

[0053] At the same time, the latch 70 and the catch 37 engage with each other, so that the lid 20 is held by the latch 70 and locked. The lid 20 then returns to being substantially flush with the vehicle body 1. Therefore, when the lid 20 and the inner lid 60 are both fully closed, a gap exists between the second recess 36 and the flat plate portion 67, i.e., between the lid mounting portion 31 and the inner lid 60.

[0054] Furthermore, the seal portion 39 of the lid mounting member 30 elastically contacts the periphery of the opening 41 of the box 40 to seal the gap between the lid mounting member 30 and the box 40 .

[0055] As described above in detail, according to this embodiment, the following effects can be obtained. (1) In this embodiment, an inner lid 60 that enables the exterior side of the DC charging port 52 to be opened and closed is attached to the upper surface 53 of the charging port 50. The lid mounting portion 31 of the lid 20 is formed with an inner lid guide portion 33 that abuts against the inner lid 20 when the lid 20 is moved in its closing direction. Therefore, even when an operation to close the lid 20 is performed with the inner lid 60 open, the inner lid 60 abuts against the inner lid guide portion 33, allowing the inner lid 60 to be moved in the closing direction. As a result, even when an operation to close the lid 20 is performed with the inner lid 60 open, for example, when the charger forgets to close the inner lid 60, the lid 20 and the inner lid 60 can be closed. In other words, the charger does not need to close the inner lid 60; they only need to close the lid 20. Furthermore, the inner lid 60, the connection portion between the inner lid 60 and the upper surface portion 53 of the charging port 50, and the lid attachment portion 31 of the lid 20 can be prevented from being deformed or damaged.

[0056] (2) In this embodiment, the inner lid 60 is formed with a protruding piece 65 that protrudes toward the lid 20 and abuts against the inner lid guide portion 33. Therefore, when manually opening the inner lid 60, the inner lid 60 can be easily opened by hooking a finger on the protruding piece 65.

[0057] (3) In this embodiment, the inner lid guide portion 33 follows the trajectory of the protruding piece 65, so that the lid 20 and the inner lid 60 can be closed even when the inner lid 60 is open, for example, when the lid 20 is closed while the inner lid 60 is forgotten to be closed.

[0058] (4) In this embodiment, the protruding piece 65 has a protruding portion 66 that protrudes from the inner lid 60 toward the lid 20, and a flat portion 67 that extends from the tip portion of the protruding portion 66 approximately parallel to the upper surface portion 53 of the charging port 50 and in a direction away from the upper surface portion 53 of the charging port 50.The inner lid guide portion 33 has a first recess 34 and a second recess 36 that accommodates the protruding piece 65 and can abut against the tip edge portion 68 of the flat portion 67.Therefore, when manually opening the inner lid 60, the inner lid 60 can be easily opened by hooking a finger on the flat portion 67 of the protruding piece 65.

[0059] (5) In this embodiment, the second recess 36 and the intermediate flat portion 35 are configured so that when the lid 20 is pressed slightly inward from the surface of the vehicle body 1 by the push-latch type latch 70, the second recess 36 presses the flat portion 67 inward, and the cover portion 63 abuts against the upper surface portion 53 of the charging port 50, moving the inner lid 60 to the fully closed position. Therefore, when the lid 20 is fully closed, the inner lid 60 can also be reliably closed.

[0060] (6) Furthermore, when the inner lid 60 is fully closed, the frame portion 64 of the inner lid 60 abuts against the wall surface 56 of the DC charging port 52, fixing the inner lid 60 in place. This prevents the inner lid 60 and the upper surface portion 53 of the charging port 50 from repeatedly coming into and out of contact with each other due to, for example, vibrations from the road surface or vehicle vibrations while driving, thereby preventing the generation of abnormal noise.

[0061] (7) In this embodiment, the lid attachment portion 31 has a shape that is substantially the same as the opening 41 of the box 40 that accommodates the charging port 50, and is formed with a seal portion 39 that elastically contacts the vicinity of the opening 41 of the box 40 when the lid 20 is closed, thereby preventing water and dust that may enter between the vehicle body 1 and the lid 20 from entering the charging port 50. Furthermore, compared to when a seal portion that elastically contacts the recess 3 of the vehicle body 1 is formed on the lid 20, the seal portion can be made smaller, resulting in cost reduction.

[0062] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the object of the present invention.

[0063] For example, in this embodiment, the charging port 50 complies with the charging standard CCS (Combined Charging System), but it can also be applied to other charging standards.

[0064] For example, in this embodiment, the inner lid 60 is described as being a type that is attached to the DC charging port 52 of the CCS, but it may also be attached to both the DC charging port 52 and the AC charging port 51. This is also true for other charging standards.

[0065] For example, in this embodiment, the inner lid 60 is attached to the upper surface 53 of the charging port 50, but it may also be attached near the opening 41 of the box 40.

[0066] For example, in this embodiment, the flat portion 67 is abutted against the second recess 36 and pressed in the direction of closing the inner lid 60, but the intermediate flat portion 35 of the inner lid guide portion 33 may be abutted against the lid portion 63 of the inner lid 60 and pressed in the direction of closing the inner lid 60, and the lid portion 63 may be abutted against the upper surface portion 53 of the charging port 50 to bring the inner lid 60 into a fully closed position.
