Description

[Technical field]

[0001] The present invention relates to a charging unit for a vehicle. [Background technology]

[0002] Conventionally, a vehicle charging unit is known that includes a body as a vehicle member having an opening, and a lid box as a housing that is inserted into the opening and assembled to the body (see Patent Document 1).

The inlet is electrically connected to a power source mounted on the vehicle. By fitting the charging connector to the inlet, it is possible to charge the vehicle's power source from the charging device.

[0003] In such a vehicle charging unit, a stud bolt and a through hole are provided between the body and the lid box as a guide portion for guiding insertion of the lid box into the opening. The stud bolt is provided in the lid box and protrudes linearly from the lid box toward the body. The through hole is provided in the body and is formed passing through the body so that the stud bolt can be inserted therethrough. By inserting the stud bolt into the through hole, it is possible to guide insertion of the lid box into the opening. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2015-157505 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the vehicle charging section as described in the above Patent Document 1, the stud bolt as the guide portion protrudes linearly, so that the insertion direction of the housing into the opening of the vehicle member is linear. In linear insertion, for example, if the outer surface of the housing has a portion that interferes with the edge of the opening, it is impossible to avoid interference between the interfering portion and the edge of the opening during insertion of the housing. Alternatively, it is impossible to secure a working space by increasing the gap between the edge of the opening and the housing during insertion of the housing. For this reason, if the guide portion can only perform linear guidance, it is impossible to avoid the interfering portion or secure a working space, and the degree of freedom of assembly is reduced.

[0006] The present invention has been made in consideration of the problems inherent in the conventional technology, and an object of the present invention is to provide a vehicle charging unit that can improve the degree of freedom in assembly. [Means for solving the problem]

[0007] The vehicle charging unit in this embodiment comprises a vehicle component having an opening, and a housing that is inserted into the opening and assembled to the vehicle component, and a guide portion is provided between the vehicle component and the housing to guide the insertion of the housing into the opening, and the guide portion is provided with a change portion that changes the movement trajectory of the housing during insertion of the housing into the opening. Effect of the Invention

[0008] According to the present invention, it is possible to provide a vehicle charging section that can improve the degree of freedom in assembly. [Brief description of the drawings]

[0010] Hereinafter, the vehicle charging section according to the present embodiment will be described in detail with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for the convenience of explanation and may differ from the actual ratios.

[0011] (First embodiment) The first embodiment will be described with reference to FIGS. 1 to 8. FIG.

[0012] As shown in Fig. 1, a vehicle charging unit 1 according to this embodiment is applied to charge a power source (not shown) mounted on a vehicle (not shown) such as an electric vehicle or a hybrid vehicle. The vehicle charging unit 1 can be fitted with a charging connector (not shown) electrically connected to a charging device (not shown) disposed at, for example, a power station. By fitting the charging connector to the vehicle charging unit 1, power is supplied from the charging device to the power source, and the power source is charged.

[0013] As shown in FIGS. 1 to 8, the vehicle charging unit 1 includes a vehicle member 3 and a housing 5. The vehicle member 3 and the housing 5 include a housing member 5a and a housing member 5b.

[0014] As shown in Figs. 1, 2, and 4 to 8, the vehicle member 3 is, for example, one member constituting a vehicle body. A rectangular opening 7 is provided in the center of the vehicle member 3, penetrating the vehicle member 3. An edge 9 of the opening 7 is set to be slightly larger than the outer surface of the housing 5. A plurality of (four in this example) vehicle fixing parts 11 are provided around the opening 7 of the vehicle member 3. Each of the vehicle fixing parts 11 extends cylindrically outward from one surface side of the vehicle member 3, and a nut having a screw hole formed therein is fixed integrally thereto.

[0015] As shown in FIGS. 1 to 3 and 5 to 8, the housing 5 is made of an insulating material such as synthetic resin. The housing 5 is formed in a rectangular shape similar to the opening 7 of the vehicle member 3 so that it can be inserted into the opening 7. An inlet arrangement section 13 is provided in the center of the housing 5, in which an inlet (not shown) electrically connected to a power source that can be fitted with the charging connector is arranged. The inlet is fixed to the inlet arrangement section 13 via fixing means (not shown) such as a screw or engaging means (not shown) for mutual engagement. The inlet supplies power from the charging device to the power source by fitting with the charging connector, thereby charging the power source.

[0016] An actuator mounting portion 17 is provided on the upper side of one surface of the housing 5, in which an actuator 15 that detects the state of the charging connector and the inlet is disposed. The actuator 15 is fixed to the actuator mounting portion 17 via a plurality of (here, two) screws 19. The actuator 15 is provided with a detection portion 21 that detects the state of the inlet and the charging connector. On the side of the actuator 15 opposite to the detection portion 21, for example, a protrusion 23 for operating the actuator 15 is provided. The protrusion 23 protrudes outward from the outer surface of the housing 5.

[0017] A plurality of (four in this case) housing fixing portions 25 each having a hole are provided on the outer surface of the housing 5 and extend outward. A plurality of (four in this case) bolts 27 can be inserted into the hole of the housing fixing portions 25. The hole of the housing fixing portions 25 respectively coincides with the vehicle fixing portions 11 when the housing 5 is inserted into the opening 7 of the vehicle member 3. The housing 5 is fixed to the vehicle member 3 by inserting the bolt 27 into the hole of the housing fixing portion 25 and fastening the bolt 27 to the vehicle fixing portion 11. A guide portion 29 is provided between the housing 5 and the vehicle member 3.

[0018] 1 to 8, guide portion 29 guides insertion of housing 5 into opening 7 when housing 5 is attached to vehicle member 3. Guide portion 29 has an extension portion 31 provided on housing 5 and an insertion hole 33 provided on vehicle member 3.

[0019] The extension portion 31 protrudes outward from the outer surface of the housing 5, and then extends linearly toward the vehicle member 3. The upper wall of the extension portion 31 connects both side walls. The bottom wall of the extension portion 31 is opened so that a sliding portion 37, which will be described later, can be inserted therein. A plurality of extension portions 31 (two in this example) are provided on the housing 5.

[0020] The insertion holes 33 are provided around the opening 7 of the vehicle member 3, penetrating the vehicle member 3 so that the extending portions 31 can be inserted therethrough. The insertion holes 33 are opened to a size that allows the extending portions 31 to move in the up and down direction when inserted therethrough. A plurality of insertion holes 33 (two in this example) are provided in the vehicle member 3 so that the number of insertion holes 33 is the same as the number of extending portions 31. The extending portions 31 are inserted into the insertion holes 33 when the housing 5 is assembled to the vehicle member 3.

[0021] The guide portion 29 has a rail portion 35 provided on the extension portion 31 and a sliding portion 37 provided in the insertion hole 33 .

[0022] A pair of rail portions 35 are provided on the upper wall sides of both side walls of extension portion 31, and extend into extension portion 31 along the extension direction of extension portion 31. Rail portions 35 are open at their front end side in the insertion direction of housing 5 into opening 7, and closed at their rear end side in the insertion direction.

[0023] The sliding portion 37 protrudes upward from the lower end of the edge of the insertion hole 33, and then extends along the insertion direction of the housing 5 into the opening 7. Both sides of the extending portion of the sliding portion 37 are engageable with the pair of rail portions 35, 35. When the extending portion 31 is inserted into the insertion hole 33, the sliding portion 37 engages with the rail portion 35 from the opening of the rail portion 35. When the housing 5 is inserted into the opening 7, the sliding portion 37 slides against the rail portion 35. The insertion of the housing 5 into the opening 7 is guided by the sliding between the sliding portion 37 and the rail portion 35.

[0024] Here, when the rail portion 35 is formed linearly, the housing 5 moves linearly relative to the opening 7 due to the sliding of the rail portion 35 and the sliding portion 37. At this time, if the edge portion 9 of the opening 7 and the outer surface of the housing 5 have the same shape, the housing 5 can be moved without interfering with the edge portion 9 of the opening 7. However, the protrusion portion 23 of the actuator 15 protrudes from the outer surface of the housing 5. Therefore, if the housing 5 moves linearly, the protrusion portion 23 interferes with the edge portion 9 of the opening 7, and the housing 5 cannot be moved. Therefore, the guide portion 29 is provided with a change portion 39 that changes the movement trajectory of the housing 5 during insertion of the housing 5, and changes the distance between the edge portion 9 of the opening 7 and the housing 5.

[0025] The change portion 39 is provided on the rail portion 35 and is disposed between the insertion start position and the insertion end position of the housing 5 into the opening 7. The change portion 39 has a step portion 41 formed in a stepped shape on the rail portion 35. The step portion 41 is an inclined surface that is continuously inclined from an upper portion to a lower portion so that an upper portion, which is the insertion start position of the housing 5 into the opening 7, and a lower portion, which is the insertion end position, are stepped in the rail portion 35. The step portion 41 slides against the sliding portion 37 during the insertion of the housing 5 into the opening 7. The sliding of the step portion 41 and the sliding portion 37 changes the movement trajectory of the housing 5 upward. For this reason, it is not necessary to complicate the insertion operation of the housing 5 into the opening 7, and the movement trajectory of the housing 5 can be changed by a simple operation.

[0026] In the guide portion 29, when the insertion of the housing 5 into the opening 7 is started, the upper part of the rail portion 35 and the sliding portion 37 slide. At this time, a gap through which the protrusion 23 can pass is formed between the upper end of the edge portion 9 of the opening 7 and the upper surface of the housing 5. In addition, the housing fixing portion 25 is disposed downward with respect to the vehicle fixing portion 11. In the middle of the insertion of the housing 5 into the opening 7 where the protrusion 23 has passed the edge portion 9 of the opening 7, the step portion 41 of the rail portion 35 and the sliding portion 37 slide in the guide portion 29. Due to the sliding between the step portion 41 and the sliding portion 37, the movement trajectory of the housing 5 changes upward. At this time, the upper end of the edge portion 9 of the opening 7 and the upper surface of the housing 5 are brought closer to each other so that the gap becomes smaller. When the sliding between the step portion 41 and the sliding portion 37 is completed, the lower part of the rail portion 35 and the sliding portion 37 slide in the guide portion 29. At this time, the outer surface of the housing 5 is inserted into the opening 7. As the insertion of the housing 5 into the opening 7 continues, the housing fixing part 25 comes into contact with the vehicle fixing part 11, and the insertion of the housing 5 into the opening 7 is completed. At this time, the hole part of the housing fixing part 25 and the vehicle fixing part 11 are aligned, and the housing 5 can be fixed to the vehicle member 3 via the bolt 27.

[0027] In the guide section 29 having the change portion 39, the movement trajectory of the housing 5 can be changed by the change portion 39 during insertion of the housing 5 into the opening 7. By changing the movement trajectory of the housing 5, the gap between the edge 9 of the opening 7 and the housing 5 can be changed. For example, by widening the gap between the edge 9 of the opening 7 and the housing 5, it is possible to prevent interference between the protrusion 23 of the actuator 15 protruding from the outer surface of the housing 5 due to movement of the housing 5 and the edge 9 of the opening 7. Therefore, during insertion of the housing 5, it is possible to avoid interfering parts and ensure working space, thereby improving the degree of freedom in assembly.

[0028] Here, there is a possibility that the housing 5 may be improperly assembled into the opening 7 of the vehicle member 3 in a different orientation, for example, upside down. Therefore, the guide portion 29 is provided with a restricting portion 43 that restricts the insertion of the housing 5 when the housing 5 is inserted into the opening 7 in a different orientation.

[0029] The restricting portion 43 protrudes upward from the upper wall of the extension portion 31. When the housing 5 is inserted into the opening 7 in the correct orientation, the restricting portion 43 allows the sliding portion 37 to be inserted into the rail portion 35 without interfering with the edge of the insertion hole 33. On the other hand, when the housing 5 is inserted into the opening 7 in a different orientation, i.e., upside down, the restricting portion 43 abuts against the sliding portion 37 and restricts the insertion of the extension portion 31 into the insertion hole 33. When the housing 5 is inserted into the opening 7 in a different orientation other than upside down, the restricting portion 43 abuts against the edge of the insertion hole 33 and restricts the insertion of the extension portion 31 into the insertion hole 33. Therefore, when the housing 5 is assembled to the vehicle member 3 in a different orientation, the housing 5 cannot move due to the abutment of the restricting portion 43, and erroneous assembly of the housing 5 to the vehicle member 3 can be prevented.

[0030] Such a vehicle charging unit 1 includes a vehicle member 3 having an opening 7, and a housing 5 that is inserted into the opening 7 and assembled to the vehicle member 3. A guide portion 29 that guides the insertion of the housing 5 into the opening 7 is provided between the vehicle member 3 and the housing 5. The guide portion 29 is provided with a change portion 39 that changes the movement trajectory of the housing 5 during insertion of the housing 5 into the opening 7.

[0031] In the guide section 29 having the changing section 39, the moving trajectory of the housing 5 can be changed by the changing section 39 during insertion of the housing 5 into the opening 7. By changing the moving trajectory of the housing 5, the gap between the edge 9 of the opening 7 and the housing 5 can be changed. Therefore, during insertion of the housing 5, it is possible to avoid interfering portions and ensure working space.

[0032] Therefore, in such a vehicle charging unit 1, the degree of freedom in assembly can be improved.

[0033] Furthermore, guide portion 29 has rail portion 35 that is provided in housing 5 and extends along the insertion direction of housing 5 into opening 7, and sliding portion 37 that is provided on vehicle member 3 and can slide along rail portion 35. Transition portion 39 has step portion 41 that is provided in rail portion 35 in a stepped shape.

[0034] Since the change portion 39 has a stepped portion 41 provided in a stepped shape on the rail portion 35, the sliding portion 37 is positioned at the stepped portion 41 during insertion of the housing 5 into the opening 7, thereby changing the movement trajectory of the housing 5. Therefore, it is not necessary to complicate the insertion operation of the housing 5 into the opening 7, and the movement trajectory of the housing 5 can be changed with a simple operation.

[0035] The guide portion 29 is provided with a restricting portion 43 that restricts the insertion of the housing 5 when the housing 5 is inserted into the opening 7 in a different orientation.

[0036] Therefore, when the housing 5 is assembled to the vehicle member 3 in a different orientation, the restricting portion 43 restricts the insertion of the housing 5 into the opening 7, thereby preventing erroneous assembly of the housing 5 to the vehicle member 3.

[0037] Second embodiment The second embodiment will be described with reference to FIGS.

[0038] In this embodiment, the vehicle charging unit 101 is provided with a stopper portion 103 in the guide portion 29 that restricts movement of the housing 5 in the direction of removal from the opening 7 when the housing 5 is inserted into the opening 7.

[0039] Note that the same symbols are used for configurations similar to those in the first embodiment, and functional descriptions will be omitted as the reader will refer to the first embodiment, but since the configurations are similar, the actions and effects obtained are equivalent.

[0040] As shown in Figs. 9 to 16, in the vehicle charging section 101 according to this embodiment, a notched avoiding section 105 for avoiding interference with the protrusion 23 of the actuator 15 is provided at the edge 9 of the opening 7 of the vehicle member 3. In the guide section 29, the orientation of the extension section 31 is upside down. The extension section 31 has an open upper wall and a bottom wall connecting both side walls. A pair of rail sections 35 are provided on the bottom wall sides of both side walls of the extension section 31. The restricting section 43 protrudes downward from the bottom wall of the extension section 31. The sliding section 37 protrudes downward from the upper end of the edge of the insertion hole 33 and then extends along the insertion direction of the housing 5 into the opening 7.

[0041] The change portion 39 is provided on the rail portion 35 and is disposed between the insertion start position and the insertion end position of the housing 5 with respect to the opening 7. The change portion 39 has a step portion 41 formed in a step shape on the rail portion 35. The step portion 41 is a step shape between a lower portion, which is a position before the insertion end position of the housing 5 with respect to the opening 7, and an upper portion, which is the insertion end position, in the rail portion 35. The step portion 41 moves the sliding portion 37, which has been sliding with the lower portion of the rail portion 35, to the upper portion of the rail portion 35 before the insertion end position, which is the middle of the insertion of the housing 5 into the opening 7. The movement of the sliding portion 37 by the step portion 41 changes the movement trajectory of the housing 5 downward. Therefore, it is not necessary to complicate the insertion operation of the housing 5 into the opening 7, and the movement trajectory of the housing 5 can be changed by a simple operation.

[0042] In the guide section 29 according to this embodiment, when the insertion of the housing 5 into the opening 7 is started, the lower part of the rail section 35 and the sliding section 37 slide. At this time, the protrusion 23 of the actuator 15 protruding from the outer surface of the housing 5 coincides with the avoidance section 105 of the edge section 9 of the opening 7. In addition, the housing fixing section 25 is disposed above the vehicle fixing section 11. Before the insertion of the housing 5 into the opening 7 is completed, the sliding section 37, which has been sliding against the lower part of the rail section 35, moves to the upper part of the rail section 35 by the step section 41 in the guide section 29. The movement of the sliding section 37 by the step section 41 changes the movement trajectory of the housing 5 downward. At this time, the hole of the housing fixing section 25 and the vehicle fixing section 11 coincide with each other. When the insertion of the housing 5 into the opening 7 is continued, the housing fixing section 25 comes into contact with the vehicle fixing section 11, and the insertion of the housing 5 into the opening 7 is completed. Then, a bolt 27 is inserted into the hole of the housing fixing portion 25 and fastened to the vehicle fixing portion 11 , whereby the housing 5 is fixed to the vehicle member 3 .

[0043] The guide portion 29 according to this embodiment is provided with a stopper portion 103 that restricts movement of the housing 5 in a direction in which the housing 5 leaves the opening 7. The stopper portion 103 is an opposing surface of the step portion 41 that is disposed opposite the sliding portion 37 in the direction in which the housing 5 leaves the opening 7 at the insertion end position of the housing 5 into the opening 7. The stopper portion 103 abuts against the sliding portion 37 when the housing 5 tries to move in the direction in which the housing 5 leaves the opening 7. The abutment of the stopper portion 103 and the sliding portion 37 restricts the housing 5 from moving in the direction in which the housing 5 leaves the opening 7, and the housing 5 can be prevented from leaving the opening 7. Therefore, the fixing operation of the housing fixing portion 25 and the vehicle fixing portion 11 with the bolt 27 can be stably performed.

[0044] In such a vehicle charging unit 101, the guide portion 29 is provided with a stopper portion 103 that restricts movement of the housing 5 in the direction of removal from the opening 7 when the housing 5 is inserted into the opening 7.

[0045] Therefore, the stopper portion 103 prevents the housing 5 from moving in a direction away from the opening 7, and the housing 5 can be stably assembled to the vehicle member 3. In addition, the operation of assembling the housing 5 to the vehicle member 3 can be stably performed.

[0046] Although the present embodiment has been described above, the present embodiment is not limited to this, and various modifications are possible within the scope of the gist of the present embodiment.

[0047] For example, in the vehicle charging unit according to the first embodiment, the guide unit is not provided with a stopper portion, but this is not limiting, and the guide unit according to the first embodiment may be provided with a stopper portion.

[0048] Further, the change section changes the movement trajectory of the housing in the up-down direction, but this is not limited thereto, and the movement trajectory of the housing changed by the change section may be in any direction, for example, left-right direction.

[0049] Further, the step portion of the transition portion changes the movement locus of the housing in one step, but this is not limiting. For example, a plurality of step portions may be provided to change the movement locus of the housing in multiple steps.

[0050] In addition, the extension portion and the rail portion are provided on the housing, and the insertion hole and the sliding portion are provided on the vehicle member, but this is not limited to this, and the extension portion and the rail portion may be provided on the vehicle member, and the insertion hole and the sliding portion may be provided on the housing.

[0051] Further, although two guide portions are provided between the vehicle member and the housing, this is not limiting, and one guide portion, or three or more guide portions may be provided between the vehicle member and the housing. [Explanation of symbols]
