Disclosure of Invention

Technical problem to be solved by the invention

On the one hand, if water enters the vicinity of the charging port for some reason, the water may enter from a gap between a wall surface on which the charging port is mounted and the charging port. Such water immersion may accelerate degradation of resin and rubber parts, in addition to causing corrosion and contamination of metal parts. Further, since the shape and size of the charging port may vary depending on the charging standard, if the gap is sealed with a sealing member such as waterproof rubber or a grommet, a different sealing member should be prepared for each shape of the charging port, and sufficient water stopping performance may not be obtained. In particular, in vehicles having charging ports of different shapes at various destinations, there are problems that water stopping performance is lowered and performance is likely to vary.

An object of the present invention is to provide a charging port structure of a vehicle, which is designed to solve the above-described problems and can improve water stopping performance with a simple structure. The present invention is not limited to this purpose, and the operation and effect derived from each configuration described in the "embodiment" described later can be another object of the present invention by utilizing the operation and effect that cannot be obtained by the conventional technique.

Means for solving the problems

The charging port structure of a vehicle disclosed herein includes: an opening portion formed on an outer panel of the vehicle and openable and closable by a lid; an inlet fixed in a state of being inserted from the vehicle inner side into and conducted through an opening formed in an inner panel opposed to an outer panel, and provided facing an opening portion of the outer panel; a charging port holder which is fitted into an opening portion of the outer panel from an outer side of the vehicle, is provided upright in a columnar shape from the outer panel toward the inner panel, and constitutes an inner peripheral wall of the charging port so as to surround the connection terminal of the inlet; a cylindrical rib embedded in the opening of the inner panel together with the inlet and provided upright toward the outer panel side to surround the periphery of the connection terminal of the inlet; and a first sealing member provided at an inner plate side end portion of the charging port holder and elastically connected to an outer circumferential surface of the rib to seal a gap between the rib and the charging port holder.

Effects of the invention

According to the disclosed vehicle charging port structure, water stopping performance can be improved by a simple structure.

Detailed Description

[1. Constitution ]

Fig. 1 is a perspective view of a vehicle 10 to which a structure of a charging port 1 as an embodiment is applied. An opening portion 3 that incorporates an inlet 9 and can be opened and closed by a lid 11 is provided on an outer panel 2 (fig. 2) of the vehicle 10. The inlet 9 is a member for external charging provided with, for example, a connection terminal 12 (a joint). The inlet 9 is fixed in a state of being inserted into and conducted through an opening 16 formed in the inner panel 6 facing the outer panel 2 on the vehicle inside, and is provided facing the opening 3 of the outer panel 2. As shown in fig. 2, for example, a plurality of connection terminals 12 are provided to protrude in a cylindrical shape toward the outside of the inlet 9, and a power supply line 15 (wire harness) connecting the connection terminals 12 and a charging circuit of the vehicle 10 is connected to the inside of the inlet 9. As shown in fig. 3, a drain hose 18 for discharging moisture entering from the connection terminal 12 to the outside of the vehicle is connected to the vicinity of the connection portion between the power supply line 15 and the inlet 9. In addition, "upper", "lower", "inner", and "outer" shown in fig. 3 indicate directions (an upper direction, a lower direction, a vehicle width direction outer side direction, a vehicle width direction inner side direction) with respect to the vehicle 10 as a reference.

Charging port 1 shown in fig. 1 is disposed in a rear side portion of vehicle 10. Fig. 2 is an exploded perspective view for explaining a surrounding structure of an inlet 9 built in the charging port 1. The charging port 1 is provided with an outer plate 2, a charging port support 4, a first sealing member 5, an inner plate 6, an inlet support 7, an inlet support sealing member 8 and an inlet 9, wherein the outer plate 2 is provided with an opening portion 3.

The charging port holder 4 is a pillar-shaped member extending inward in the vehicle width direction from the edge of the opening portion 3, and is fixed to the outer panel 2. The cross-sectional shape of the vehicle width direction outer side end portion of charging port holder 4 is formed in a shape corresponding to opening 3 (for example, a square shape with rounded corners). On the other hand, the sectional shape of the vehicle width direction inside end portion is formed in a shape (for example, a peanut shape) surrounding the connection terminal 12 of the inlet 9. The charging port holder 4 is fitted into the opening portion 3 of the outer panel 2 from the vehicle outside, is provided upright from the outer panel 2 toward the inner panel 6 in a columnar shape, and constitutes an inner peripheral wall of the charging port 1 so as to surround the connection terminal 12 of the inlet 9. In the inner peripheral wall, a gradient at a portion above the connection terminal 12 is formed as a downward gradient substantially toward the vehicle inside. On the other hand, the gradient of the portion located below the connection terminal 12 is formed to be a downward gradient toward the vehicle outside to avoid the retention of raindrops or water droplets.

As shown in fig. 3, the charging port bracket 4 is provided upright in a cylindrical shape from the outer panel 2 toward the inner panel 6 so as to surround the connection terminal 12 of the inlet 9. A lid 11 that openably closes the opening 3 is attached to the charging port holder 4. By opening the cover 11, the connection terminal 12 of the inlet 9 becomes visible from the outside of the vehicle 10, and the charging gun or the charging cord can be connected. Further, the axial direction (orientation) of the connection terminal 12 is set to be inclined obliquely upward in view of facilitating connection of the charging gun or the charging cord.

As shown in fig. 3, the charging port holder 4 is fixed to the outer panel 2 by bolts, or is fitted and fixed to the outer panel 2 by fitting claws provided on the charging port holder 4. As shown in fig. 3, the opening 3 of the outer panel 2 is provided with a receiving portion 19 extending from an entrance (vehicle exterior side) of the opening 3 toward the vehicle compartment side. The receiving unit 19 is fitted with the charging port holder 4 and positioned. Further, a second seal 13 and a third seal 14 are attached to the vehicle width direction outer side end portion of the charging port bracket 4.

The second seal 13 is an annular seal member provided near the cover 11 of the receiving portion 19, and seals a gap between the receiving portion 19 and the charging port holder 4. The third seal 14 is an annular seal member provided at the vehicle-compartment-side bottom of the receiving portion 19, and is located closer to the gap between the vehicle-compartment-side seal receiving portion 19 and the charging port holder 4 than the second seal 13. These

seals

13, 14 seal the gap between the outer panel 2 and the charging port bracket 4. The charging port holder 4 may be formed integrally with the outer panel 2, or may be welded and fixed to the outer panel 2. In the case where the outer panel 2 and the charging port bracket 4 are integrally formed, the second seal 13 and the third seal 14 may be omitted.

The first seal 5 is a seal member provided at the vehicle width direction inner side (inner panel 6 side) end portion of the charging port holder 4. The first seal 5 is formed of, for example, a soft resin having appropriate elasticity and is molded in two colors to be integrated with the charging port holder 4 formed of a hard resin. The first seal 5 is elastically connected to an outer peripheral surface of a rib 23 described later to seal a gap between the rib 23 and the charging port holder 4. As shown in fig. 4, the first seal 5 is provided with a fixing portion 21 and a lip portion 22. The fixing portion 21 is a portion fixed to the charging port holder 4, and is formed in a columnar shape having a cross-sectional shape (for example, a peanut shape) corresponding to the vehicle width direction inside end portion of the charging port holder 4. The "front-rear inner-outer-upper-lower direction" shown in fig. 4 indicates a direction (front, rear, vehicle width direction outer side direction, vehicle width direction inner side direction, upper direction, lower direction) with respect to the vehicle 10.

The lip portion 22 extends toward the inner side of the column from the vehicle width direction inner end portion of the fixing portion 21. The first seal 5 is annular in shape with an L-shaped cross section, and is elastically connected to the outer peripheral surface of the rib 23 in a state folded back toward the outer plate 2. The lip 22 has an arcuate shape in which the tip of the lip 22 abuts against the tip of the rib 23 in a state of being elastically connected to the rib 23. As shown in fig. 5A, the vehicle width direction inside end opening of the charging port bracket 4 is in a state of being narrowed by the lip portion 22 of the first seal 5. Further, in the case where the first seal 5 is provided separately from the charging port bracket 4, the first seal 5 may be attached or adhesively fixed to the vehicle width direction inside end portion of the charging port bracket 4.

The inner panel 6 is a plate-like member to which an inlet 9 of a vehicle 10 is fixed by bolts. The inner panel 6 is provided with an opening 16 having a shape (for example, a peanut shape) corresponding to the vehicle width direction inner side end portion of the charging port bracket 4, and a fastening hole 17 for fastening the inlet bracket 7. The connection terminal 12 of the inlet 9 is inserted into the conduction opening 16 from the vehicle width direction inner side of the inner panel 6 (the back side of the inner panel 6), and is provided to protrude outward in the vehicle width direction from the inner panel 6. Further, the snap holes 17 are formed at a plurality of places around the opening 16. Further, a part of the inner panel of the vehicle 10 may be disposed as the inner panel 6, or the inner panel 6 separate from the inner panel of the vehicle 10 may be fixed to the inner panel.

The inlet bracket 7 is a ring-shaped member fixed to the opening 16 of the inner panel 6 together with the inlet 9, and is disposed separately from the inlet 9. As shown in fig. 4 and 5B, the inlet holder 7 is provided with a rib 23, an annular portion 24, a snap-in portion 25, and an inclined surface portion 26. The rib 23 is a column having a cross-sectional shape (for example, a peanut shape) corresponding to the vehicle width direction inside end portion of the charging port bracket 4, and is formed in a column shape slightly smaller than the fixing portion 21 of the first seal 5. The rib 23 is fitted into the opening 16 of the inner panel 6 together with the inlet 9, and is provided upright toward the outer panel 2 side so as to surround the periphery of the connection terminal 12 of the inlet 9. In addition, this rib 23 is provided so as to be inserted from the side opposite to the charging port bracket 4 (the vehicle width direction inner side) as viewed from the inner panel 6 to elastically connect with the lip portion 22 of the first seal 5 when the inlet 9 is fixed to the inner panel 6.

In addition, as shown in fig. 5A and 5B, each of the rib 23 on the upper side and the rib 23 on the lower side of the connection terminal 12 of the inlet 9 is in a positional relationship of contacting the lip 22 of the first seal 5. In other words, the annular lip 22 presses outward in the vehicle width direction while being in contact with the leading end of the cylindrical rib 23 and elastically deformed as a whole, thereby forming a seal structure between the charging port bracket 4 and the inlet bracket 7.

The annular portion 24 is a flat portion extending from the vehicle width direction inner end portion (base end portion) of the rib 23 to the cylindrical outer side, and is provided around the opening 16 of the inner panel 6. In other words, the rib 23 stands from the annular portion 24 in the circumferential direction of the annular portion 24. The annular portion 24 is formed in a shape corresponding to the end of the charging port holder 4 on the inner plate 6 side. The annular portion 24 is provided so as to contact the edge (the vehicle width direction inner side surface) of the opening 16 of the inner panel 6. As shown in fig. 3, the inlet housing seal 8 is sandwiched and sealed between the annular portion 24 and the inlet 9. The annular portion 24 is sandwiched between the inner plate 6 and the inlet 9. The inlet port support 7 and the inlet port 9 are fixed in a state of being bonded, for example, by the inlet port support seal 8.

The catching portion 25 is a portion that is caught in the catching hole 17 of the inner panel 6, and is inserted from the vehicle width direction inner side with respect to the catching hole 17 and fixed to the inner panel 6. The snap-in portion 25 is provided radially outward of the annular portion 24 than the rib 23. As shown in fig. 4, the inlet bracket 7 is provided with a plurality of engaging portions 25. The engaging portion 25 is formed with an engaging claw protruding outward from an end edge of the engaging hole 17 in a state of being inserted into the conductive engaging hole 17. In addition, the protruding directions of the engagement claws are set to be opposite to each other with respect to the pair of engagement portions 25 that face each other with the connection terminal 12 of the inlet 9 interposed therebetween. Thereby, the click state with respect to the inner plate 6 of the inlet bracket 7 is stabilized.

As shown in fig. 3, the inclined surface portion 26 is a planar portion extending obliquely upward from the tip end portion of the rib 23 toward the inlet 9 below the connection terminal 12 of the inlet 9 so as to form an inclined surface in the gap between the rib 23 and the connection terminal 12. The inclined surface portion 26 is provided between the inlet holder 7 and the inlet 9, and is formed in a range below the connection terminal 12 when the inlet 9 is viewed from the front. For example, as shown in fig. 4, in the rib 23 provided in a ring shape, the inclined surface portion 26 may extend from the vehicle width direction outer side end portion of the rib 23 located at the lower half (substantially half). As shown in fig. 3, the inclination angle of the inclined surface portion 26 is preferably set to an angle that is a downward gradient toward the vehicle width direction outer side.

[2. Effect ]

The "upper", "lower", "inner", and "outer" shown in fig. 6A indicate directions (upper direction, lower direction, vehicle width direction outer side direction, vehicle width direction inner side direction) with respect to the vehicle 10. When the inlet 9 is fixed to the inner panel 6, the inlet 9 and the inlet bracket 7 are pushed from the vehicle width direction inside toward the outside so that the click portion 25 of the inlet bracket 7 engages with the click hole 17 of the inner panel 6. At this time, the rib 23 of the inlet bracket 7 is inserted into the inside of the opening 16 and contacts the lip 22 of the first seal 5.

As shown in fig. 6B, the lip portion 22 of the first seal 5 elastically deforms as the rib 23 moves outward in the vehicle width direction, and the lip portion 22 is in a state of being bent and deformed relative to the fixing portion 21 while maintaining the contact between the rib 23 and the lip portion 22. Thereby, the gap between the charging port holder 4 and the inlet holder 7 is sealed. Then, the engagement portion 25 of the inlet bracket 7 is engaged with the engagement hole 17 of the inner plate 6, and the installation of the inlet bracket 7 is completed.

In the configuration of charging port 1 of the present embodiment, even when water enters the inside of charging port 1 for some reason, it is possible to appropriately discharge the water. For example, even in the case where water droplets adhere to the inner surface of the charging port bracket 4 due to rainfall during charging, the first seal 5 seals between the charging port bracket 4 and the inlet bracket 7, preventing moisture from entering. In addition, the second seal 13 and the third seal 14 seal a gap between the receiving portion 19 of the outer panel 2 and the charging port bracket 4, and prevent moisture from entering. Likewise, inlet support seal 8 seals the gap between inlet support 7 and inlet 9, preventing ingress of moisture.

Water droplets adhering to the upper portion of the connection terminal 12 on the inner surface of the charging port holder 4 move toward the vehicle interior side and adhere to the peripheral surface of the connection terminal 12. The water droplets flow downward along the outer surface of the connection terminal 12 protruding in a cylindrical shape, and are guided along the upper surface of the inclined surface portion 26 into the inner surface of the charging port holder 4. Then, water droplets on the inner surface of the charging port holder 4 are discharged to the outside of the vehicle through the gap between the outer panel 2 and the cover 11. The moisture introduced into the connection terminal 12 is discharged to the outside of the vehicle through the drain hose 18.

[3. Effect ]

(1) The charging port 1 is provided with: an opening portion 3 formed on an outer panel 2 of the vehicle 10 and openable and closable by a lid 11; and an inlet 9 fixed in a state of being inserted from the vehicle inside to be conducted into an opening 16 formed in the inner panel 6, and provided facing the opening 3 of the outer panel 2. Further, a charging port holder 4 is provided, which is fitted into the opening portion 3 of the outer panel 2 from the vehicle outside, is provided in a columnar shape standing from the outer panel 2 toward the inner panel 6, and constitutes an inner peripheral wall of the charging port 1 so as to surround the connection terminal 12 of the inlet 9. In addition, a columnar rib 23 is provided, which is fitted into the opening 16 of the inner panel 6 together with the inlet 9, and is provided upright toward the outer panel 2 side so as to surround the periphery of the connection terminal 12 of the inlet 9. Further, a first seal 5 is provided at the end of the charging port holder 4 on the inner plate 6 side, and elastically contacts the outer peripheral surface of the rib 23 to seal the gap between the rib 23 and the charging port holder 4.

With this configuration, the gap around the inlet 9 can be easily sealed by simply moving the inlet bracket 7 having the inlet 9 and the ribs 23 outward in the vehicle width direction, and a water stop structure can be formed. In addition, since the first seal 5 is elastically urged against the rib 23, even if the pressure (water pressure) acting on the gap between the charging port holder 4 and the inlet holder 7 is increased, for example, high sealing performance is easily maintained. Therefore, water stopping properties around the inlet 9 can be improved by a simple structure.

(2) The charging port 1 is structurally provided with an inlet bracket 7 separated from an inlet 9. The inlet bracket 7 is provided with a ring-shaped portion 24 and ribs 23. With this structure, even in the case where the shape of the inlet 9 differs depending on the type of vehicle and the destination of the vehicle 10, the structures of the charging port bracket 4, the first seal 5, the inner panel 6, and the like can be made common by changing the shape of the inlet bracket 7. Therefore, the number of parts and the manufacturing cost can be reduced while improving the water stopping performance around the inlet 9 by a simple structure.

(3) For example, as shown in fig. 3, the annular portion 24 of the inlet bracket 7 is sandwiched between the inner plate 6 and the inlet 9. With this configuration, the inlet bracket 7 can be prevented from slipping off the inner panel 6, and the accuracy of the attachment position of the inlet bracket 7 can be improved. In addition, since the positional deviation of the inlet bracket 7 is less likely to occur, the water stop performance can be prevented from being lowered.

(4) The inlet bracket 7 is provided with a clamping part 25 clamped on the inner plate 6. The snap-in portion 25 is provided radially outward of the annular portion 24 with respect to the rib 23. With this structure, the inlet bracket 7 can be attached to the inner panel 6 by a simple operation, and the water stop structure can be easily realized. In addition, water can be prevented from flooding the snap portion 25 or water from entering from the snap portion 25, and water-stopping properties around the inlet 9 can be further improved. Further, by arranging the pair of engaging portions 25 opposing each other sandwiching the connection terminal 12 of the inlet 9 in the projecting direction of the engaging claw, the engaging state of the inlet bracket 7 with respect to the inner panel 6 can be stabilized. Therefore, water stopping properties around the inlet 9 can be further improved.

(5) The inlet bracket 7 is provided with an inclined surface portion 26. The inclined surface portion 26 is provided extending from the rib 23 to form an inclined surface on a gap between the rib 23 and the connection terminal 12. With this structure, water can be prevented from entering from the gap between the inlet bracket 7 and the inlet 9, and the water stopping performance around the inlet 9 can be further improved. In addition, since it is easy to prevent water from flooding the inlet bracket seal 8, the mounted state of the inlet bracket 7 and the inlet 9 can be stabilized.

The inclined surface portion 26 is formed in a range below the connection terminal 12 when the inlet 9 is viewed from the front. With this configuration, even when water droplets adhere to the circumferential surface of the connection terminal 12, for example, and the water droplets drop downward, the water droplets can reliably flow outward in the vehicle width direction along the inclined surface portion 26. Therefore, water stopping properties around the inlet 9 can be further improved.

(6) The charging port 1 is structurally provided with an inlet support sealing member 8 which is clamped and installed between an inlet support 7 and an inlet 9. This improves the water-stopping property of the gap between the inlet port bracket 7 and the inlet port 9. Therefore, water stopping properties around the inlet 9 can be improved by a simple structure. In addition, relative movement of the inlet bracket 7 with respect to the inner panel 6 is less likely to occur, and the accuracy of the mounting position of the inlet bracket 7 can be improved. Further, since the positional deviation of the inlet bracket 7 is less likely to occur, the water stopping performance can be prevented from being lowered.

(7) The first seal 5 is provided with a lip portion 22 extending toward the inner peripheral side of the charging port holder 4. The lip 22 is elastically connected to the outer peripheral surface of the rib 23 in a state folded back toward the outer panel 2 side. By elastically contacting the lip 22 with the outer peripheral surface of the rib 23 in this manner, the gap between the charging port holder 4 and the inlet holder 7 can be reliably sealed, and the water-stopping property around the inlet 9 can be further improved.

(8) For example, as shown in fig. 6B, the lip portion 22 of the first seal 5 has an arcuate shape in which the tip of the lip portion 22 abuts against the tip side of the rib 23 in a state of being elastically connected to the rib 23. With this structure, the rib 23 can be flexibly held by the flexure of the lip 22, allowing a slight relative movement of the inlet port bracket 7 with respect to the charging port bracket 4 while performing appropriate positioning. Therefore, water stopping properties around the inlet 9 can be further improved.

(9) The opening 3 of the outer panel 2 is provided with a receiving portion 19 to be fitted and positioned with the charging port holder 4. Further, an annular second seal 13 is provided near the cover 11 of the receiving portion 19, and an annular third seal 14 is provided at the bottom of the receiving portion 19 on the vehicle cabin side. With this configuration, water can be prevented from entering through the gap between the receiving portion 19 of the outer panel 2 and the charging port bracket 4, and water stopping performance around the inlet 9 can be further improved. In addition, since the charging port holder 4 is attached to the receiving portion 19 via the second seal 13 and the third seal 14, the positioning accuracy of the charging port holder 4 can be improved.

(10) As shown in fig. 3, the axial direction of the connection terminal 12 of the inlet 9 is inclined obliquely upward. With this structure, for example, compared with the case where the axial direction is set vertically upward, it is possible to make water less likely to enter the opening of the terminal, and further improve water-stopping performance around the inlet 9. In addition, the operation of connecting the charging gun or the charging wire to the inlet 9 is easy, and convenience can be improved. Even if the surface of the connection terminal 12 is submerged by water and water enters from the opening of the terminal, the water can be discharged from the drain hose 18 to the outside of the vehicle.

Further, in the structure of the charging port 1 described above, the first seal 5 is integrally molded in two colors with the charging port holder 4. For example, in a first mold, the charging port holder 4 is molded of a hard resin, and in a subsequent second mold, the first seal 5 is molded of a soft resin. In this way, by thermally fusing the first seal 5 to the charging port holder 4, the gap between the first seal 5 and the charging port holder 4 can be eliminated, and the sealing performance can be further improved. In addition, the workability of component mounting can be improved as compared with the case where the first seal 5 and the charging port holder 4 are separate components.

[4. Modification ]

The above-described embodiments are merely examples and are not intended to exclude various modifications and technical applications not explicitly shown in the present embodiments. Various modifications may be made to the respective configurations of the present embodiment without departing from the gist thereof. Further, the selection may be performed as necessary or may be appropriately combined.

For example, in the above-described embodiment, although the water stop structure of the charging port 1 is described in detail, the same structure may be applied to other inlets 9. For example, the same operations and effects as those of the above-described embodiment can be obtained by using the same configuration for the fuel supply port for replenishing fuel to the internal combustion engine, the water supply port for replenishing urea water for exhaust gas purification, or the like.

In addition, in the above-described embodiment, although the structure in which the inlet port support 7 is provided separately from the inlet port 9 is shown, the inlet port support 7 and the inlet port 9 may be formed integrally. At least, if the rib 23 is provided on the inlet 9, the same action and effect as those of the above-described embodiment can be obtained.

This application is based on Japanese application filed on 22/6/2020 (Japanese patent application No. 2020-106760), the contents of which are incorporated herein by reference.

According to the charging port structure of the vehicle of the present disclosure, it is possible to improve water stopping performance by a simple structure.
