Description

[Technical Field]

[0001] The present invention relates to a lid device that is attached to the body of a vehicle such as an automobile, closes a fuel filler port, a charging port, etc. of the vehicle body, and is openable and closable. [Background technology]

[0002] When refueling or filling an automobile fuel tank with fuel such as gasoline or hydrogen, the filler cap or filler lid that covers the filler or filler port on the vehicle body is opened, the fuel cap is removed, and fuel is added through the filler port, or a filler plug is inserted into the filler port to fill with hydrogen. Furthermore, when charging the battery installed in an electric vehicle that runs on an electric motor or a plug-in hybrid vehicle (PHV, PHEV) that runs on both an electric motor and an engine, electricity is supplied from an external charging facility (household power outlet, power source at a dedicated charging facility), the lid is opened and the charging plug is inserted into a charging socket, either a quick charging socket or a normal charging socket, and the battery is charged.

[0003] For example, Figures 5(a) and (b) disclose a tank flap 180 (also called a "lid") module with a push-push closure structure, which includes a recessed portion body having a pot portion 100 and a base portion 110 that can be inserted into an opening in the vehicle body, a passage opening 120 of the recessed portion body configured to receive a fuel filler neck in the region of the base portion 110, a fixed flange 130 that protrudes radially outward facing a direction away from the base portion 110, and a peripheral seal tab 140 that extends along the fixed flange 130 and is flexibly deformable, the peripheral seal tab 140 having a radially outer seal element 160 supported on a vehicle body plate 150 and a seal tab 170 that protrudes axially outward, the radial seal element 160 and the axial seal tab 170 being integrally formed (for example, Patent Document 1).

[0004] With the above structure, the seal element 160 contacts the body plate 150, while the seal tab 170 elastically contacts the tank flap 180, thereby preventing the intrusion of dirt, dust, and moisture into the recess.

[0005] 6 shows a lid seal structure for an automobile, which includes a housing 200 provided on the body of an automobile and having a recessed accommodation portion 210 in which a fuel filler opening or a power filler opening is disposed, a lid 220 for opening and closing the opening of the accommodation portion 210, an arm (not shown) for supporting the lid 220 and having a base end side rotatably attached to the housing 200, and a sealant 230 for sealing between the lid 220 and the housing 200, and the sealant 230 is provided in an annular shape on the peripheral edge of the housing 200, and a flange portion 240 is provided on the peripheral edge of the housing 200 so as to face the back surface of the lid 220, and a sealant 230 is provided in a widthwise intermediate portion of the flange portion 240 on the surface of the flange portion 240 facing the back surface of the lid 220. a base-forming recess 260 extending in the circumferential direction, in which a base 250 of the sealing material 230 is placed, the base 250 of the sealing material 230 being fixed to the inner surface of the base-forming recess 260; the sealing material 230 being plate-shaped and protruding from a flange 240 toward the lid 220, a lip 270 positioned radially outward as it approaches the tip of the protruding direction; and an auxiliary sealing material 280 being provided in an annular shape on the inner periphery of the lip 270, being plate-shaped and protruding from the flange 240 toward the lid 220, and positioned radially inward as it approaches the tip of the protruding direction; and further, an outer peripheral elastic material 290 protruding outward and extending annularly at the peripheral edge of the housing 200, which comes into contact with the vehicle body panel, is provided (for example, Patent Document 2).

[0006] With the above structure, when the lid 220 is in the closed state, the protruding tips of the lip portion 270 and the auxiliary sealant 280 contact the entire periphery of the back surface of the lid 220, and are pressed by the back surface of the lid 220, causing the lip portion 270 and the auxiliary sealant 280 to elastically deform and bend, thereby obtaining a double seal structure between the lid 220 and the housing 200 and further improving the sealing performance.

[0007] [Patent Document 1] US Patent Application Publication No. 2012 / 0161462 [Patent Document 2] Patent Publication No. 2021-54186 Summary of the Invention [Problem to be solved by the invention]

[0008] However, with the technology of Patent Document 1, for example, when a high-pressure car wash is performed, that is, when a large amount of high-pressure water enters the gap between the body plate 150 and the tank flap 180, the water may pass through the seal between the tank flap 180 and the seal tab 170 and enter the recess.

[0009] On the other hand, in the technology of Patent Document 2, the lip portion 270 and the auxiliary sealing material 280 extend from the base 250 fixed to the inner surface of the base-forming recess 260 to the outside of the vehicle, and are designed to increase the reaction force from the sealing material 230 to the lid 220 in order to accommodate the push-push closing structure. Therefore, when the lid 220 is closed, the lid 220 may protrude from the outer surface of the vehicle body, which will result in a poor appearance.

[0010] The present invention solves the above-mentioned problems and aims to provide a lid device that prevents water from entering the energy supply port even in the case of high-pressure car washing, etc., and prevents the lid from protruding from the outer surface of the vehicle body when the lid is closed. [Means for solving the problem]

[0011] A lid device according to a first aspect of the present invention for solving the above problem comprises a box attached to the outer surface of the vehicle body and having an opening formed therein corresponding to a supply port for supplying energy to the vehicle, a lid for opening and closing the exterior side of the supply port, an arm connected to the lid and box and enabling the lid to be opened and closed, and a sealing member for sealing between the box and the lid, wherein a flange portion is formed on the peripheral portion of the box so as to face the interior side of the lid, and the sealing member comprises a base portion extending from the exterior side of the flange portion toward the exterior of the vehicle, an outer sealing portion branching from the exterior tip portion of the base and extending on the peripheral side of the flange portion toward the exterior of the vehicle, and an inner sealing portion extending on the non-peripheral side of the flange portion toward the exterior of the vehicle, and wherein when the lid is closed, both the outer sealing portion and the inner sealing portion elastically contact the interior side of the lid.

[0012] In the lid device of the first aspect of the present invention, a flange portion is formed on the peripheral portion of the box so as to face the interior side of the lid, and the sealing member comprises a base portion extending from the exterior side of the flange portion toward the exterior of the vehicle, an outer seal portion branching from the exterior tip portion of the base and extending toward the peripheral side of the flange portion and toward the exterior of the vehicle, and an inner seal portion extending toward the non-peripheral side of the flange portion and toward the exterior of the vehicle.When the lid is closed, both the outer seal portion and the inner seal portion elastically contact the interior side of the lid, so that, for example, when a high-pressure car wash is performed, even if water passes through the abutment surface between the lid and the outer seal portion, the inner seal portion can prevent water from entering the supply port for supplying energy to the vehicle.

[0013] Furthermore, since the base is formed and the outer seal portion and inner seal portion branch off from the outer end of the base on the vehicle exterior side, the reaction force from the outer seal portion and inner seal portion to the lid when the lid is closed can be suppressed. As a result, the lid can be prevented from protruding from the outer surface of the vehicle body while ensuring the sealing performance between the lid and the base, and therefore the appearance can be prevented from being deteriorated.

[0014] A lid device according to a second aspect of the present invention is the lid device of the first aspect, wherein the inner seal portion is formed shorter in cross section than the outer seal portion.

[0015] The function of preventing dirt, dust, moisture, and rain from entering the supply port for supplying energy to the vehicle is mainly performed by the outer seal portion that extends around the periphery of the lid and to the outside of the vehicle, and the outer seal portion can block much of the water even when a high-pressure car wash is performed.

[0016] In the lid device according to the second aspect of the present invention, the inner seal portion is formed shorter in cross section than the outer seal portion, so that the inner seal portion blocks water that passes through the contact surface between the lid and the outer seal portion, preventing water from entering the supply port for supplying energy to the vehicle. Furthermore, the reaction force from the inner seal portion to the lid when the lid is closed can be suppressed, preventing the lid from protruding from the outer surface of the vehicle body and preventing a deterioration in appearance.

[0017] A lid device according to a third aspect of the present invention is a lid device in which, in the first and second aspects, the sealing member has an outer peripheral lip that seals between the peripheral edge of the flange portion and the outer surface of the vehicle body, and the outer peripheral lip and the base are integrally formed.

[0018] In the lid device according to the third aspect of the present invention, the sealing member has an outer lip that seals between the peripheral edge of the flange portion and the outer surface of the vehicle body, thereby sealing between the box and the outer surface of the vehicle body.

[0019] In addition, because the outer lip and base are integrally formed, the contact area between the seal member and the flange is increased, which prevents the seal member from peeling off from the flange.Furthermore, because there is no step between the outer lip and the base at the flange, the appearance is improved.

[0020] A lid device according to a fourth aspect of the present invention is the lid device according to the first to third aspects, in which the rotation shaft portion of the arm is connected to a lid opening / closing motor, and the lid is opened and closed by driving the lid opening / closing motor.

[0021] In the lid device according to the fourth aspect of the present invention, the rotation shaft of the arm is connected to a lid opening / closing motor, and the lid is opened and closed by driving the lid opening / closing motor, so the base, inner seal, and outer seal of the seal member are not pressed toward the interior of the vehicle more than they are in the state after the lid is closed, as is the case with a push-push closing structure, and as a result, the durability of the inner seal and outer seal of the seal member is increased.

[0022] Furthermore, even in a structure that includes a base portion extending from the outer surface of the flange toward the outside of the vehicle, and an outer seal portion and an inner seal portion branching off from the outer tip portion of the base, the lid can be opened and closed reliably. [Effects of the Invention]

[0023] a lid device comprising: a box attached to the outer surface of a vehicle body and having an opening formed therein corresponding to a supply port for supplying energy to the vehicle; a lid for opening and closing the exterior side of the supply port; an arm connected to the lid and the box and enabling the lid to be opened and closed; and a sealing member for sealing between the box and the lid; a flange portion formed on the peripheral portion of the box and arranged to face the interior side of the lid; and the sealing member comprising: a base portion extending from the exterior side of the flange portion to the exterior side of the vehicle; an outer seal portion branching from the exterior tip portion of the base and extending to the peripheral side of the flange portion and to the exterior side of the vehicle; and an inner seal portion extending to the non-peripheral side of the flange portion and to the exterior side of the vehicle; and when the lid is closed, both the outer seal portion and the inner seal portion elastically contact the interior side of the lid, so that, for example, even if water passes through the abutment surface between the lid and the outer seal portion when a high-pressure car wash is performed, the inner seal portion can prevent water from entering the supply port for supplying energy to the vehicle.

[0024] Furthermore, since the base is formed with an outer seal portion and an inner seal portion branching off from the outer end of the base on the vehicle exterior side, the reaction force from the outer seal portion and the inner seal portion to the lid when closed can be suppressed. As a result, the lid can be prevented from protruding from the outer surface of the vehicle body while ensuring sealing performance between the lid and the inner seal portion, thereby preventing deterioration of the appearance. For example, even if water passes through the contact surface between the lid and the outer seal portion during a high-pressure car wash, the inner seal can prevent water from entering the supply port for supplying energy to the vehicle.

DETAILED DESCRIPTION OF THE INVENTION

[0026] An embodiment of the present invention will be described with reference to FIGS. 1 to 4. The following embodiment describes a lid device 1 for a charging port 13, which is a supply port for supplying energy, located on the left front fender (body exterior surface 11) of a vehicle 10 designed for an electric vehicle or a plug-in hybrid vehicle. However, the present invention can also be applied to cases where the charging port 13 is located on the right front fender or other locations. In FIG. 1, the upper side of the page is above the vehicle, the lower side is below the vehicle, the left side is the front of the vehicle, and the right side is the rear of the vehicle. The present invention can be applied not only to charging ports for charging electricity, but also to other energy supply ports for refueling or filling an automobile fuel tank with fuel such as gasoline or hydrogen.

[0027] As shown in FIG. 1, a lid device 1 for a charging port 13 is attached to the left front fender (vehicle body exterior surface 11) of a vehicle 10. The lid device 1 includes a box 20 attached to a recess 12 in the vehicle body exterior surface 11, a lid 50 that opens and closes the exterior space of the box 20, and an arm 30 that connects the lid 50 and the box 20. The arm 30 includes a first support arm 31 that movably supports the lid 50, and a second support arm 34 that is positioned below the first support arm 31 on the vehicle 10.

[0028] The lid 50 can be moved upward over the vehicle 10 and along the vehicle body exterior surface 11 of the vehicle 10 from a fully open position shown in FIG. 1 , in which a charging plug from the charging equipment side can be connected to and accessed from a charging socket disposed in the opening 21 of the box 20, to a fully closed position shown in FIG. 2 , in which the charging plug is removed. In the fully closed position shown in FIG. 2 , the lid 50 covers the charging socket. Therefore, the lid 60 is designed to open downward over the vehicle 10.

[0029] Additionally, the first support arm 31 and the second support arm 34 connect the lid 50 and the box 20, and support the lid 50 so that it can move in the vertical direction of the vehicle 10 and along the outer surface 11 of the vehicle body 10. In the process of opening, the lid 50 is lifted to the outside of the outer surface 11 of the vehicle body and moves downward along the outer surface 11 of the vehicle body.

[0030] A flange portion 22 is formed on the outer periphery of the box 20, and the box 20 is connected to the flange portion 22 by a side wall portion 23. The box 20 has a bottom surface 24 that is located on the vehicle interior side of the flange portion 22 and in which the opening 21 is formed. The flange portion 22 is formed to face the vehicle interior side surface 53 of the lid 50.

[0031] Additionally, the bottom surface portion 24 is formed with box recesses 25 located on the front and rear sides of the opening 21 and recessed toward the vehicle interior from the bottom surface portion 24. A first support arm 31 and a second support arm 34, which will be described later, are attached to the box recesses 25.

[0032] 1, the first support arm 31 has first support arm vertical side portions 32 that are rotatably connected to first support arm box-side connecting portions 27 formed in the box recess 25, and the front and rear first support arm vertical side portions 32 are connected by first support arm connecting portions 33, which are connected to first support arm lid-side connecting portions 51 formed on the lid 50. Note that the first support arm vertical side portions 32 do not have to be connected by the first support arm connecting portions 33, and may be connected to the lid 50 individually.

[0033] The first support arm 31 is formed so that the spacing of the first support arm vertical side portion 32 narrows on the lid 50 side. This is because, in FIG. 1, the flange portion 22, side wall portion 23, and bottom surface portion 24 of the box 20 are formed so as to narrow upward, and this prevents the first support arm vertical side portion 32 from interfering with the side wall portion 23 when the lid 50 is opened or closed. For this reason, in FIG. 2, the lid 50 side of the rear first support arm vertical side portion 32 does not appear in the cross-sectional view and is therefore shown by a dashed line. The same is true for the front first support arm 31.

[0034] The second support arm 34 has second support arm vertical side portions 35 that are rotatably connected to second support arm box-side connecting portions 28 formed in the box recess 25, and the front and rear second support arm vertical side portions 35 are connected by second support arm connecting portions 36, which are connected to second support arm lid-side connecting portions 52 formed on the lid 50. Note that the second support arm vertical side portions 35 do not have to be connected by the second support arm connecting portions 36, and may be connected to the lid 50 individually.

[0035] Furthermore, the second support arm 34 is formed with a curved portion 37 (FIG. 2) that curves downward toward the vehicle when the lid 50 is open, in a position close to the connecting portion between the side wall portion 23 and the flange portion 22 of the box 20. By providing the curved portion 37, the lid 50 can be opened more widely toward the vehicle downward than if the curved portion 37 were not provided.

[0036] In this embodiment, the box 20 is made of a material obtained by mixing glass fiber with polypropylene (PP), which is excellent in terms of rigidity, strength, etc. The first support arm 31 and the second support arm 34 are made of nylon (polyamide), an engineering plastic, specifically nylon 6. However, the box 20, the first support arm 31, and the second support arm 34 are not limited to the above materials.

[0037] The first support arm box side connector 27 of the first support arm 31 and the second support arm box side connector 28 of the second support arm 34 are connected to a lid opening / closing motor (not shown), and when the lid opening / closing motor is driven, the first support arm 31 and the second support arm 34 rotate to open and close the lid 50. The lid opening / closing motor may be connected to either the first support arm 31 or the second support arm 34, rather than to both.

[0038] As shown in Figures 1 to 4, a seal member 40 is formed on the flange portion 22 of the box 20. The seal member 40 has an outer peripheral lip 41 that extends from the peripheral edge 26 of the flange portion 22 outward. The outer peripheral lip 41 is curved convexly toward the vehicle interior and tapered toward its tip. When attached to the recess 12 in the vehicle body outer surface 11, the outer peripheral lip 41 elastically contacts the recess 12 in the vehicle body outer surface 11, thereby sealing between the vehicle body outer surface 11 and the box 20. Note that the outer peripheral lip 41 may not be curved but may be linear.

[0039] The seal member 40 also includes a base 42 that extends in a substantially straight line in a substantially vertical direction from the exterior surface 22a of the flange portion 22 toward the exterior of the vehicle, an outer seal portion 43 that branches off from the exterior tip portion of the base 42 and extends toward the peripheral edge 26 of the flange portion 22, curving convexly toward the exterior of the vehicle, and an inner seal portion 44 that extends toward the non-peripheral edge side, opposite the peripheral edge 26 of the flange portion 22, curving convexly toward the exterior of the vehicle. Note that the outer seal portion 43 and the inner seal portion 44 do not have to be curved.

[0040] The base 42 is formed to be thicker than the outer seal portion 43 and the inner seal portion 44. Moreover, the outer seal portion 43 and the inner seal portion 44 are formed to have approximately the same thickness from the outer end portion of the base 42 on the vehicle exterior side to their end portions (outer seal portion end portion 43a and inner seal portion end portion 44a).

[0041] As shown in Figure 3, the outer seal portion 43 is formed longer than the inner seal portion 44, and when the lid 50 is open, the outer seal portion tip 43a of the outer seal portion 43 is located on the outside of the vehicle relative to the inner seal portion tip 44a of the inner seal portion 44.

[0042] The base 42 and the outer peripheral lip 41 are integrally formed and connected to the outer surface 22a of the flange 22. The base 42 and the outer peripheral lip 41 may be formed separately on the flange 22.

[0043] Charging is performed in the state shown in Figure 1, and after charging, when the charging plug is removed from the charging socket and the lid opening / closing motor is driven, the first support arm 31 and the second support arm 34 rotate, moving the lid 50 upward on the vehicle 10 and along the outer surface 11 of the vehicle 10, thereby closing the lid 50 (Figure 2).

[0044] 2 and 4, when the lid 50 is closed, both the outer seal portion 43 and the inner seal portion 44 of the seal member 40 elastically contact the interior side surface 53 of the lid 50. At this time, the base 42 is hardly deformed. A space S (FIG. 4) is formed between the interior side surface 53 of the lid 50, the outer seal portion 43, and the inner seal portion 44.

[0045] Since the outer seal portion 43 is formed longer than the inner seal portion 44, as shown in Figure 4, the outer seal portion 43 bends more than the inner seal portion 44, and the contact area between the outer seal portion 43 and the interior side surface 53 of the lid 50 is larger than that of the inner seal portion 44.

[0046] In this embodiment, the sealing member 40 is made of a material obtained by mixing polypropylene (PP) with EPDM (ethylene propylene diene rubber). However, the material constituting the sealing member 40 is not limited to the above material, and the sealing member 40 can be made of rubber, thermoplastic elastomer (TPE), soft synthetic resin, etc.

[0047] As described above in detail, according to this embodiment, the following effects can be obtained. (1) A flange portion 22 is formed on the peripheral portion of the box 20 so as to face the interior side surface 53 of the lid 50, and the sealing member 40 is provided with a base portion 42 that is approximately perpendicular to the exterior side surface 22a of the flange portion 22 and extends toward the exterior of the vehicle in an approximately straight line, an outer seal portion 43 that branches off from the exterior tip portion of the base 42 and extends toward the peripheral portion of the flange portion 22 and in a convex curve toward the exterior of the vehicle, and an inner seal portion 44 that extends toward the non-peripheral side of the flange portion 22 and in a convex shape toward the exterior of the vehicle.When the lid 50 is closed, both the outer seal portion 43 and the inner seal portion 44 elastically contact the interior side surface 53 of the lid 50. Therefore, for example, when a high-pressure car wash is performed, even if water passes through the abutment surface between the lid 50 and the outer seal portion 43, the inner seal portion 44 can prevent water from entering the supply port for supplying energy to the vehicle.

[0048] (2) Furthermore, the base 42 is formed, and the outer seal portion 43 and the inner seal portion 44 are formed branching off from the outer end portion of the base 42 on the vehicle exterior side. This makes it possible to suppress the reaction force from the outer seal portion 43 and the inner seal portion 44 to the lid 50 when the lid 50 is closed. This ensures sealing performance between the lid 50 and prevents the lid 50 from protruding from the outer surface of the vehicle body, thereby preventing a deterioration in appearance.

[0049] (3) In cross section, the outer seal portion 43 is formed longer than the inner seal portion 44, and when both the outer seal portion 43 and the inner seal portion 44 elastically contact the interior side surface 53 of the lid 50, the outer seal portion 43 bends more than the inner seal portion 44, increasing the contact area with the interior side surface 53 of the lid 50. This allows the outer seal portion 43 to block rainwater, moisture, dust, dirt, etc., and even in the case of a large amount of high-pressure water, such as in a high-pressure car wash, the outer seal portion 43 can reduce the amount and pressure of water, so that the inner seal portion 44, which is shorter than the outer seal portion 43, can prevent water from entering the box 20.

[0050] (4) Furthermore, since the inner seal portion 44 is formed shorter than the outer seal portion 43, the reaction force from the inner seal portion 44 to the lid 50 when the lid 50 is closed can be suppressed.

[0051] (5) The sealing member 40 has an outer lip 41 that seals between the peripheral edge 26 of the flange portion 22 and the outer body surface 11 of the vehicle 10, thereby enabling sealing between the box 20 and the outer body surface 11 of the vehicle 10.

[0052] (6) Because the outer peripheral lip 41 and the base 42 are integrally formed, the contact area with the flange portion 22 is increased, which prevents the flange portion 22 from peeling off. Furthermore, because there is no step between the outer peripheral lip 41 and the base 42 at the flange portion 22, the appearance is improved.

[0053] (7) The lid opening / closing motor rotates the first support arm 31 and the second support arm 34, moving the lid 50 upward on the vehicle 10 and along the vehicle body exterior surface 11 of the vehicle 10, thereby closing the lid 50. This prevents the inner seal portion 44 and the outer seal portion 43 of the seal member 40 from being pressed toward the interior of the vehicle more than when the lid 50 is closed, as occurs with a push-push closing structure. As a result, the durability of the inner seal portion 44 and the outer seal portion 43 of the seal member 40 is increased. Furthermore, even in a structure including a base portion 42 extending from the exterior surface 22a of the flange portion 22 toward the exterior of the vehicle, and the outer seal portion 43 and inner seal portion 44 branching from the exterior tip portion of the base portion 42, the lid 50 can be opened and closed reliably.

[0054] In addition to the aspects set forth in the claims, the present invention also includes the following aspects. 5. The lid device according to claim 3, wherein a rotation shaft of the arm of the lid is connected to a lid opening / closing motor, and the lid is opened and closed by driving the lid opening / closing motor.

[0055] 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.

[0056] For example, in the above embodiment, the lid device was of a type that could move upward on the vehicle and along the outer surface of the vehicle body from a fully open position (Figure 1) where the charging socket is accessible to the charging plug on the charging equipment side to which the charging socket is connected to, to a fully closed position (Figure 2).However, the present invention can also be applied to a lid device of a type that supports the lid as disclosed in Patent Document 1 and Patent Document 2 and has an arm whose base end is rotatably attached to the housing.

[0057] For example, in the above embodiment, the lid device was of a type in which the first support arm and the second support arm were rotated by a lid opening / closing motor, and the lid was moved upward on the vehicle and along the outer surface 11 of the vehicle body to close the lid, but the present invention can also be applied to lid devices with a push-push closing mechanism disclosed in Patent Document 1 and Patent Document 2.
