The first electrode member 11 is provided, for example, at the vehicle front end position of the electric vehicle 200, and is provided at the same height as the connection portion on the charging device 300 side. The first electrode member 11 is connected to the battery 3 inside the electric vehicle 200 via a cable or the like. The first electrode member 11 is made of, for example, a conductive metal material (copper, copper alloy, or the like) as a base material, and has a shape to be electrically connected to the second electrode member 21. As shown in FIGS. 2 and 3, the first electrode member 11 has a convex portion 11 a formed in the facing direction (X direction) facing the second electrode member 21. The convex portion 11a is configured to be insertable into the concave portion 21b formed in the second electrode member 21.

Is. The moving mechanism 13 includes, for example, metal coil springs provided at both ends in the vertical direction (Z direction) and both ends in the width direction (Y direction) of the first electrode member 11. In the electric vehicle 200, the moving mechanism 13 supports the first electrode member 11 so as to be movable in a direction (including a vertical direction and a width direction) orthogonal to the front-rear direction (X direction). The moving mechanism 13 is assumed to be electrically insulated from the first electrode member 11.

  The second electrode member 21 is a connecting portion that is arranged to be exposed to the outside of the charging device 300 and is connected to the electric vehicle 200. The second electrode member 21 is supported by, for example, a support member (not shown) that is erected upward from the ground, and is arranged at substantially the same height as the first electrode member 11 provided in the electric vehicle 200. The second electrode member 21 is connected to the charging unit 5 inside the charging device 300 via a cable or the like. The second electrode member 21 is made of, for example, a conductive metal material (copper, copper alloy, or the like) as a base material, and has a shape to be electrically connected to the first electrode member 11. As shown in FIGS. 2 and 3, the second electrode member 21 has a facing surface 21a, a recess 21b, and a connecting surface 21c.

  The facing surface 21a is a flat surface formed in the facing direction (X direction) of the second electrode member 21. The concave portion 21b is a portion formed in the facing direction (X direction) and into which the convex portion 11a of the first electrode member 11 is inserted. The concave portion 21b has a bottom surface on the front side, and the convex portion 11a is inserted into the internal space. As shown in FIG. 4, the recess 21b of the present embodiment is formed in a groove shape extending in the vertical direction (Z direction). The connecting surface 21c is a flat surface that connects the facing surface 21a and the recess 21b. The connection surface 21c of the present embodiment is an inclined surface that is inclined from the recess 21b in the facing direction (X direction) toward the direction opposite to the recess 21b. The connecting surface 21c is formed in the width direction with the recess 21b interposed therebetween. Further, the connecting surface 21c is formed symmetrically in the width direction with the facing direction as the central axis. The sliding member 31 is laminated on the coupling surface 21c of the present embodiment.

  The sliding member 31 is made of a material different from that of the second electrode member 21 having the concave portion 21b, and has the guide surface 32 that guides the convex portion 11a to slide into the concave portion 21b. The guide surface 32 is an exposed surface of the sliding member 31 opposite to the connecting surface 21c in the stacking direction, and has more edges than the connecting surface 21c. The edge of the present embodiment is, for example, a scale indicating surface roughness or the like. That is, the guide surface 32 having a small number of edges has a rough surface, and the guide surface 32 having a large number of edges has a small surface roughness. The sliding member 31 of the present embodiment is configured by combining, for example, a first sliding surface 32a, a second sliding surface 32b, and a third sliding surface 32c. The first sliding surface 32a has the roughest surface roughness among the three levels of roughness. The first sliding surface 32a is made of, for example, a brush made of metal or hard bristles. The second sliding surface 32b has an intermediate surface roughness among the three levels of roughness. The second sliding surface 32b is made of, for example, a thick non-woven fabric. The third sliding surface 32c has the finest surface roughness among the three levels of roughness. The third sliding surface 32c is made of, for example, a foam such as sponge, urethane foam, or polyethylene. In this way, the guide surface 32 is formed such that the roughness of the three sliding surfaces gradually shifts from the rough form to the dense form in the direction toward the recess 21b. In other words, the guide surface 32 is formed so that the edge gradually increases in the direction toward the recess 21b. The guide surface 32 may be formed so that the edge gradually decreases in the direction toward the recess 21b.

  It is preferable that the material applied to the three sliding surfaces of the sliding member 31 is selected according to the form of dust or poor contact that is assumed under the environment of the electrode structure 1, and is, for example, metal or resin. , Natural products, etc. The form of the sliding surface is preferably selected according to the form of dust or poor contact that is assumed under the environment of the electrode structure 1, and is formed, for example, in the form of a brush, a woven fabric, a non-woven fabric, a file, a sponge, or the like. To be done. For example, in an environment in which the electric vehicle 200 mainly travels on an unpaved road or the like, a brush with hard bristles is selected in consideration of adhesion of mud or sand. In addition, in an environment in which the electric vehicle 200 runs on a road immediately after paving a factory, a sponge containing a cleaning component is selected assuming oil stains. Further, in an environment in which the electric vehicle 200 runs on a seaside road or a paved road in winter, a hard brush containing a cleaning component is selected in consideration of salt damage and the like. The sliding member 31 may be laminated on the coupling surface 21c via an adhesive or the like, or may be laminated by driving a rivet or the like.

  The guide surface 32 is an inclined surface that inclines toward the opposite side of the recess 21b from the recess 21b in the facing direction when the projection 11a is inserted in the recess 21b. The guide surface 32 moves the convex portion 11a of the first electrode member 11 and the concave portion 21b of the second electrode member 21 relative to each other in a direction orthogonal to the facing direction of the second electrode member 21, so that the convex portion 11a is concave. To guide you.

  Next, the connecting operation between the first electrode member 11 and the second electrode member 21 in the electrode structure 1 will be described with reference to FIGS. 3 and 4.

  First, a driver (not shown) of the electric vehicle 200 drives the electric vehicle 200 toward the charging device 300 while moving the electric vehicle 200 forward, and the first electrode member 11 of the electric vehicle 200 is moved to the second position of the charging device 2. The electrode member 21 is contacted. At this time, the convex portion 11 a of the first electrode member 11 contacts the guide surface 32 of the sliding member 31. For example, the convex portion 11a is in contact with the first sliding surface 32a of the guide surface 32. When the user further moves the electric vehicle 200 forward, the convex portion 11a moves the guide surface 32 to the concave portion 21b while the first electrode member 11 moves in the width direction relative to the second electrode member 21 by the moving mechanism 13. Slide toward. The convex portion 11a slides on the guide surface 32 in the order of the first sliding surface 32a, the second sliding surface 32b, and the third sliding surface 32c, and moves toward the concave portion 21b of the second electrode member 21. For example, the convex portion 11a slides on the first sliding surface 32a to remove dust and the like adhering to the surface. For example, when the first sliding surface 32a is composed of a brush having hard bristles, mud or sand attached to the surface of the convex portion 11a is removed. Next, the convex portion 11a slides on the second sliding surface 32b, so that dust and the like not completely removed by the first sliding surface 32a are removed. For example, when the second sliding surface 32b is made of non-woven fabric or the like, fine dust and sand particles attached to the surface of the convex portion 11a are removed. Further, the convex portion 11a slides on the third sliding surface 32c, so that fine dust and the like that are not completely removed by the first sliding surface 32a and the second sliding surface 32b are removed. For example, when the third sliding surface 32c is made of sponge, oil or the like attached to the surface of the convex portion 11a is removed. In addition, the convex portion 11a slides on the sliding surfaces 32a, 32b, and 32c of the three sliding members, so that the corroded portion on the surface is removed stepwise. For example, when the first sliding surface 32a is composed of a brush having hard bristles, salt particles that promote corrosion are removed. When the second sliding surface 32b is made of a non-woven fabric, the oxide film or the like in the corroded portion is removed. When the third sliding surface 32c is made of sponge, the corroded portion can be polished. The convex portion 11a is slid on the guide surface 32 and then inserted into the concave portion 21b. By thus inserting the convex portion 11a into the concave portion 21b, the first electrode member 11 and the second electrode member 21 can be electrically connected. Since the portion of the guide surface 32 with which the convex portion 11a abuts differs depending on the situation of the electric vehicle 200, it abuts the second sliding surface 32b or the third sliding surface 32c depending on the situation of the electric vehicle 200. Even if the sliding is started toward the concave portion 21b later, the same effect as described above can be obtained.

  The electrode structure 1 described above is provided in the electric vehicle 200, the first electrode member 11 connected to the battery 3, the second electrode member 21 connected to the charging unit 5, and the electric vehicle 200 in a stopped state. The moving mechanism 13 that connects the first electrode member 11 and the second electrode member 21 by moving the first electrode member 11 relative to the second electrode member 21. The first electrode member 11 has a convex portion 11 a formed in a facing direction facing the second electrode member 21. The second electrode member 21 is a guide formed so as to face each other and having a concave portion 21b into which the convex portion 11a of the first electrode member 11 is inserted and a convex portion 11a of the first electrode member 11 slidingly guiding the concave portion 21b. And a surface 32. The guide surface 32 is formed with a plurality of edges.

  In the electrode structure 1 according to this embodiment, the protrusion 11a of the first electrode member 11 slides on the guide surface 32 of the sliding member 31 to remove dust and the like or the corroded portion attached to the protrusion 11a. You can As a result, the dirt attached to the electrodes can be removed with an inexpensive and simple structure, and the maintenance frequency of the electrodes can be suppressed. Further, since the convex portion 11a of the first electrode member 11 is inserted into the concave portion 21b of the second electrode member 21 to establish a connected state, the first electrode member 11 and the second electrode member 21 can be connected with a simple configuration. Can be connected.

  Further, the electrode structure 1 according to the present embodiment is different from the second electrode member 21 having the recess 21b, and includes the sliding member 31 laminated on the connecting surface 21c connected to the recess 21b. The guide surface 32 is an exposed surface of the sliding member 31 opposite to the connecting surface 21c in the stacking direction, and has more edges than the connecting surface 21c. Thereby, for example, when the first electrode member 11 and the second electrode member 21 are connected, the convex portion 11a of the first electrode member 11 faces the concave portion 21b of the second electrode member 21 and the guide surface of the sliding member 31. Slide 32. As a result, dust and the like adhering to the surface of the convex portion 11a can be removed, and a corroded portion on the surface of the convex portion 11a can be removed, so that the above effect can be made more reliable. Further, for example, when the function of the sliding member 31 deteriorates with time or the removal of dust or the like is insufficient, it becomes possible to remove the sliding member 31 from the connecting surface 21c and replace the sliding member 31 with improved maintainability. It becomes possible.

  Further, in the electrode structure 1 according to the present embodiment, the guide surface 32 is an inclined surface that is inclined from the recess 21b in the facing direction toward the direction opposite to the recess 21b. When the convex portion 11a in contact with the guide surface 32 slides, the electric vehicle 200 moves forward and part of the force of the first electrode member 11 toward the second electrode member 21 side is due to the action of the inclined surface. The pushing force is dispersed in the direction orthogonal to the front-back direction, and the pushing force guides the convex portion 11a to the concave portion 21b. As a result, the action of the inclined surface and the force of the electric vehicle 200 moving to move the first electrode member 11 toward the second electrode member 21 cause the first electrode member 11 and the second electrode member 21 to cross the front-back direction. The convex portion 11a can be guided to the concave portion 21b by moving the convex portion 11a relative to the concave portion 21b.

  In addition, in the electrode structure 1 according to the present embodiment, the guide surface 32 is formed so that the edge gradually increases in the direction toward the recess 21b. This makes it easier to remove dust of different sizes and types attached to the surface of the convex portion 11a and corrosion of different degrees. Further, the sliding surfaces (32a to 32c) of the same type but different in surface roughness are arranged stepwise along the sliding direction to make the surface of the convex portion 11a cleaner. Therefore, it is possible to reduce the electric resistance of the contact between the convex portion 11a and the concave portion 21b.

  In the above-described embodiment, the second electrode member 21 has a groove shape in which the recess 21b extends in the vertical direction (Z direction), but the present invention is not limited to this. FIG. 5: is a top view which shows schematic structure of the electrode member and sliding member which concern on the modification of embodiment. In the second electrode member 21A according to the modified example of the embodiment, the recess 21ba has a hemispherical bottom surface. The connection surface 21ca according to the modified example is formed so as to have a reduced diameter from the recess 21ba in the facing direction toward the direction opposite to the recess 21ba. In other words, the connecting surface 21ca has a mortar-like shape recessed from the opening on the facing surface 21a toward the recess 21ba. The coupling surface 21ca is formed radially around the recess 21ba. A sliding member 31A is laminated on the coupling surface 21ca.

  The sliding member 31A is made of a material different from that of the second electrode member 21A having the concave portion 21ba, and has the guide surface 32A that guides the convex portion 11a to slide into the concave portion 21ba. The guide surface 32A is an exposed surface of the sliding member 31 on the side opposite to the connecting surface 21c in the stacking direction, and has more edges than the connecting surface 21c. The guide surface 32A according to the modified example is configured by combining a first sliding surface 32Aa, a second sliding surface 32Ab, and a third sliding surface 32Ac that are concentrically arranged around the recess 21ba. The exposed surface of the first sliding surface 32Aa has the roughest surface roughness among the three levels of roughness. The first sliding surface 32Aa is made of, for example, a brush made of metal or hard bristles. The exposed surface of the second sliding surface 32Ab has an intermediate surface roughness among the three levels of roughness. The second sliding surface 32Ab is made of, for example, a thick non-woven fabric. The exposed surface of the third sliding surface 32Ac has the finest surface roughness among the three levels of roughness. The third sliding surface 32c is made of, for example, a foam such as sponge, urethane foam, or polyethylene. Thus, the guide surface 32A is formed so that the edge gradually increases in the direction toward the recess 21ba. Note that the guide surface 32A may be formed so that the edge gradually decreases in the direction toward the recess 21ba. The sliding member 31 may be laminated on the coupling surface 21c via an adhesive or the like, or may be laminated by driving a rivet or the like.

  In the electrode structure 1 according to the modified example of the present embodiment, the protrusion 11a of the first electrode member 11 slides on the guide surface 32A of the sliding member 31A to remove dust or the like attached to the protrusion 11a or a corroded portion. It can be removed. Further, since the guide surface 32A is formed so that the edge gradually increases in the direction toward the concave portion 21ba, it is possible to further remove dust of different sizes and types attached to the surface of the convex portion 11a and corrosion of different degrees. It will be easier. As a result, dirt attached to the electrodes can be removed with an inexpensive and simple structure. Further, the sliding surfaces (32Aa to 32Ac) of the same kind but different in surface roughness are arranged stepwise along the sliding direction to make the surface of the convex portion 11a cleaner. Therefore, it is possible to reduce the electric resistance of the contact point between the convex portion 11a and the concave portion 21ba.

  In addition, in the said embodiment and modification, although the 1st electrode member 11 was applied to the electric vehicle 200 and the 2nd electrode member 21 was applied to the charging device 300, it demonstrated, but it is not limited to this. .. That is, the first electrode member 11 may be applied to the charging device 300 and the second electrode member 21 may be applied to the electric vehicle 200. In this case, the electrode structure 1 is provided in the electric vehicle 200, the second electrode member 21 connected to the battery 3, the first electrode member 11 connected to the charging unit 5, and the electric vehicle 200 in a stopped state. The moving mechanism 13 that connects the first electrode member 11 and the second electrode member 21 by moving the second electrode member 21 relative to the first electrode member 11. The second electrode member 21 has a convex portion 11 a formed in a facing direction facing the first electrode member 11. The first electrode member 11 has concave portions 21b and 21ba which are formed in opposite directions and into which the convex portion 11a of the second electrode member 21 is inserted, and the convex portion 11a of the second electrode member 21 slides to form concave portions 21b and 21ba. And guide surfaces 32, 32A for guiding to. A plurality of edges are formed on the guide surfaces 32 and 32A. With the above structure, the electrode structure 1 in the modified example of the present embodiment can obtain the same effect as that of the electrode structure 1 described above.

  Moreover, in the said embodiment and modification, although the electrode structure 1 is equipped with the sliding members 31 and 31A laminated | stacked on the connection surfaces 21c and 21ca of the 2nd electrode member 21, it is not necessarily equipped with the sliding members 31 and 31A. is not. For example, the connecting surfaces 21c and 21ca may function as the guide surface 32. In this case, the guide surface 32 has more edges than the surface of the second electrode member 21 (for example, the facing surface 21a). Thus, it is possible to remove dust and the like adhering to the surface of the convex portion 11a without removing the sliding members 31 and 31A on the connecting surfaces 21c and 21ca, and to remove a corroded portion on the surface of the convex portion 11a. You can As a result, the component cost required for the electrode structure 1 can be suppressed.

  Further, in the above-described embodiment and modified example, the sliding members 31, 31A are configured by combining the three sliding surfaces as the guide surfaces 32, 32A, but the invention is not limited to this. For example, the sliding members 31 and 31A may have uniform surface roughness on the guide surfaces 32 and 32A. That is, it is preferable that the sliding members 31 and 31A are selected according to the form of dust or poor contact that is assumed under the environment of the electrode structure 1, and is made of, for example, metal, resin, natural product, or the like. .. The form of the sliding members 31 and 31A is preferably selected according to the form of dust or poor contact that is assumed under the environment of the electrode structure 1, and examples thereof include a brush, a woven fabric, a non-woven fabric, a file-like form, and a sponge-like form. Etc. Further, as described above, the sliding members 31 and 31A may be configured to include a cleaning component in a brush, a sponge, or the like, for example.

  Further, in the above-described embodiment and modification, the battery 3 is illustrated as the first electric device and the charging unit 5 is illustrated as the second electric device, but the present invention is not limited thereto. For example, the first electric device may be the communication device of the electric vehicle 200, and the second electric device may be the communication device of the charging device 300.

  Further, in the above-described embodiment and modification, the moving mechanism 13 is a coil spring made of metal, which is provided at both ends of the first electrode member 11 in the vertical direction (Z direction) and both ends in the width direction (Y direction). Although configured, it is not limited to this. For example, the moving mechanism 13 connects the first electrode member 11 to the second electrode member 21 by moving the first electrode member 11 from the standby position to the connection position while the electric vehicle 200 is stopped. May be included. The standby position is a position where the moving mechanism 13 is in the bent state and the first electrode member 11 is stored in the electric vehicle 200. The connection position is a position where the first electrode member 11 is in contact with the second electrode member 21 when the moving mechanism 13 is in the extended state.
