[0037] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0038] Figure 1 It is a perspective view showing the structure near the display unit 1 and its installation part in a charging port display system (charging port display device) according to an embodiment of the present invention. Figure 2 It is a longitudinal sectional view showing the structure near the display unit 1 and its installation part according to the first embodiment. In addition, Figure 2 It is Figure 1 A sectional view taken along line A-A described in Figure 3 It is an explanatory view of the detailed structure of the display unit 1 according to the first embodiment, and is a view of observing the vicinity of the display unit 1 and its installation part from the front.

[0039] As Figure 1 , 2 shown, the display unit 1 in a charging port display system 21 according to an embodiment of the present invention is provided on a power receiving part 3 provided on, for example, the left outer wall 2 (outer wall) of an electric vehicle (hereinafter referred to as a vehicle).

[0040] The power receiving part 3 is provided with a connector 5 to which the charging plug at the end of a charging cable (power supply line) is connected. Electric power is supplied from an external power source via the charging cable (including the charging plug) and the connector to charge a charging battery (not shown) mounted on the vehicle.

[0041] An opening 6 having a substantially rectangular shape is provided on the left outer wall 2 of the vehicle, and a rectangular box-shaped frame 8 is provided so as to cover the opening 6 of the left outer wall 2 from the inside. That is, a concave portion 9, which is a space recessed from the left outer wall 2 of the vehicle toward the inside, is formed by the frame 8.

[0042] The connector 5 is fixed to the bottom wall 10, which is the wall surface on the vehicle inner side (right side in the vehicle width direction) of the frame 8, and is arranged so as to face the outside of the opening 6.

[0043] A cover 15, which is a cover body covering the opening 6, is provided on the power receiving portion 3. The cover 15 is a substantially rectangular plate shape slightly larger than the opening 6, and the front side of the vehicle is supported by a hinge 16 on the inner side of the left outer wall 2.

[0044] Therefore, by closing the cover 15, a closed state in which the opening 6 is covered is formed, and by opening the cover 15, an open state in which the opening 6 is opened and a charging plug can be connected to the connector 5 is formed.

[0045] <Display portion of the first embodiment>

[0046] As Figure 3 shown, the display portion 1 in the first embodiment of the present utility model is provided on the upper wall 18 of the frame 8 and is composed of a plurality of light emitters 20 such as LEDs. The light emitter 20 can be switched to at least white, blue, yellow, and red respectively and emit light. In addition, as shown by the double-dot chain line in Figure 2 , the light emitter 20 is arranged so as to irradiate light downward toward the connector 5.

[0047] The light emitters 20 are arranged in the left and right (vehicle front-rear direction) with the same number centered on the central position in the vehicle front-rear direction of the connector 5. In the present embodiment, two groups of five light emitters 20 are provided, for a total of ten, and are designated as 20a, 20b, 20c, 20d, and 20e from the central side toward both outer sides.

[0048] Figure 4 is a structural diagram of the charging port display system 21 including the display portion 1.

[0049] As Figure 4 shown, the charging port display system 21 includes a display portion 1, a charging port display control unit 25 (charging rate input unit, display control portion), and a cover opening / closing switch 26 (cover body open detection portion).

[0050] The lid opening / closing switch 26 is provided on the vehicle to detect the opening and closing of the lid 15. The detection information of the lid opening / closing switch 26 is input to the charging port display control unit 25. In addition, charging state information (charging rate) of the current status of the vehicle's charging battery and the operating state of the vehicle's charging system are input from the charging control unit 30, which is the control device of the vehicle's charging system, to the charging port display control unit 25. As the operating state of the charging system, for example, information such as the insertion state of the charging plug into the connector 5, a failure of the charging system, and charging completion is input.

[0051] The charging port display control unit 25 includes an input / output device, a storage device (ROM, RAM, non-volatile RAM, etc.), a central processing unit (CPU), etc., and controls the operation (display control) of the light emitters 20 in the display unit 1 according to the opening / closing state of the lid 15 and the operating state of the charging system, etc.

[0052] Next, the display method in the display unit 1 of the first embodiment will be described.

[0053] The display unit 1 changes the display method according to the following various states (1) to (6).

[0054] (1) When the lid is open (guide display)

[0055] When the lid opening / closing switch 26 inputs that the lid 15 has been opened from the closed state, the charging port display control unit 25 controls the display unit 1 in such a way as to perform a guide display in which the central light emitter 20a is lit in sequence to 20b, 20c, 20d, 20e. When the outermost light emitter 20e is lit, all the light emitters 20a to 20e are lit. The light emitters 20a to 20e are all lit in white, and are lit from the light emitter 20a to 20e, for example, in 1.5 seconds. Then, all the light emitters 20a to 20e are maintained lit. In this way, when the lid is open, a guide display in which the light illuminating the connector 5 spreads from the center to the outside is performed in the display unit 1. In addition, regarding the display when the lid is open, in addition to switching from the extinguished state to the lit state as described above, the illuminance (output) of the light emitters 20a to 20e can also be increased sequentially from the inside to the outside so that strong light spreads from the inside to the outside.

[0056] (2) During standby

[0057] During the charging standby from when the above-mentioned guide display when the lid is open is performed until the charging plug is inserted into the connector 5, all the light emitters 20a to 20e flash simultaneously in white of the same color as when the lid is open, for example, at intervals of 0.8 seconds (lit and extinguished repeatedly every 0.8 seconds).

[0058] (3) During charging

[0059] While the charging plug is inserted into the connector 5 and the charging current is supplied from an external power source to the charging battery of the vehicle, i.e., during charging, all of the light emitters 20a to 20e are simultaneously made to blink, for example, at intervals of 0.8 seconds in a color different from (1) when the lid is open and (2) during standby, for example, blue.

[0060] (4) Charging completed

[0061] When the charging of the charging battery of the vehicle is completed and input from the charging control unit 30, i.e., when the charging battery is fully charged, all of the light emitters 20a to 20e are lit in the same color (blue) as (3) during charging.

[0062] (5) Warning (insertion failure)

[0063] In the case of a relatively mild non - chargeable state such as a poor insertion of the charging plug into the connector 5, all of the light emitters 20a to 20e are simultaneously made to blink, for example, at intervals of 0.5 seconds in a color different from the colors in (1) to (4) above and a color that attracts attention (for example, yellow).

[0064] (6) Warning (charging system failure)

[0065] In the case of a relatively serious non - chargeable state such as a charging system failure, all of the light emitters 20a to 20e are simultaneously made to blink, for example, at intervals of 0.5 seconds in a color different from the colors in (1) to (5) above and a color that attracts more attention than when warning in (5) (for example, red).

[0066] As described above, the vehicle equipped with the charging port display system 21 of the first embodiment has a power receiving unit 3 supplied with power from an external power source on the left outer wall 2 of the vehicle body. The power receiving unit 3 is configured to cover the recess 9 in an openable and closable manner by a lid 15. The recess 9 is provided with a connector 5, and the connector 5 is connected to a charging plug at the end of a charging cable supplied with power from an external power source.

[0067] The display unit 1 in the charging port display system 21 of the first embodiment has 10 light emitters 20 (20a to 20e are in 2 groups) arranged near the connector 5 and emitting light inside the recess 9. Moreover, when the lid opening / closing switch 26 detects the opening operation of the lid 15, the display unit 1 changes the light emission amount of the plurality of light emitters 20 to perform a guiding display for guiding the line of sight to the connector 5. Therefore, an operator around the vehicle can easily recognize the position of the power receiving unit 3 and the opening operation of the lid 15.

[0068] The light emitters 20 of the display unit 1 in the first embodiment are arranged horizontally above the connector 5 and are configured to irradiate light toward the connector 5. Therefore, the position of the power receiving unit 3, particularly the connector 5, can be easily recognized by the light emission of the light emitters 20.

[0069] In addition, when the lid is opened, a guiding display is performed in which the light emitters 20a closer to the connector 5 among the plurality of light emitters 20 are sequentially lit toward the light emitters 20e farther away. Therefore, for an operator who wants to charge and is near the vehicle, the visibility of the position of the connector 5 can be significantly improved. In particular, the visibility can be improved in either nighttime or daytime.

[0070] The guiding display is performed once, but thereafter, during the connection standby until the charging plug is connected to the connector 5, all the light emitters 20 flash simultaneously in the same color as the guiding display. Thereby, the visibility of the position of the connector 5 can also be improved during the connection standby, and the operator can be made to recognize that it is in the connection standby. In addition, since the light emitters 20 are arranged to emit light toward the connector 5, for example, the position of the connector 5 can be easily recognized at night, and the connection of the charging plug to the connector 5 becomes easy.

[0071] In addition, during charging in which power is supplied from an external power source when the charging plug is connected to the connector 5, all the light emitters 20 flash simultaneously in a color different from that of the guiding display and the connection standby. Thereby, the operator can be made to recognize that it is charging. In particular, in the present embodiment, by flashing in blue, the operator can sensually recognize that the charging system is operating normally.

[0072] Moreover, when charging is completed, by lighting all the light emitters 20 in the same color as during charging, the operator can be easily made to recognize that the charging has been completed.

[0073] Moreover, when charging is not possible due to a poor connection of the connector, all the light emitters 20 flash simultaneously in yellow, which is different from any of the displays during the guiding display, connection standby, charging, and charging completion, so that the operator can easily recognize that charging is not possible.

[0074] In addition, when there is a failure in the charging system such that charging from an external power source is not possible even when the connector 5 and the charging plug are connected, all the light emitters 20 flash simultaneously in red, which is different from the guiding display, connection standby, charging, charging completion, and non-charging, so that the situation of non-charging can be easily recognized, and the operator can be made to recognize a relatively serious abnormality.

[0075] Thus, in the present embodiment, a display unit 1 is provided near the connector 5, and the display unit 1 has a plurality of light emitters 20 capable of emitting light of various colors such as LEDs. By switching the color and display mode, an operator near the connector 5 can easily recognize various states such as the guiding display toward the connector 5 when the lid is opened, connection standby, charging, charging completion, non-charging, and failure.

[0076] <Display unit of the second embodiment>

[0077] Figure 5 This is a front view showing the display unit 40 in the charging port display system of the second embodiment of the present utility model and the structure near its mounting portion. Figure 6 This is a schematic diagram showing a display example during charging of the display unit 40 in the second embodiment.

[0078] The charging port display system 21 of the second embodiment of the present utility model is different in the display unit compared with the charging port display system 21 of the first embodiment.

[0079] As Figure 5 、 6 shown, the display unit 40 in the second embodiment is composed of a plurality of light emitters 41 such as LEDs on the bottom wall 10 (installation surface) of the housing 8 of the fixed connector 5.

[0080] The light emitters 41 in the display unit 40 are in an arc shape centered on the connector 5, and the same number of light emitters 41 are arranged radially on the left and right (vehicle front-rear direction) of the connector 5. In this embodiment, two groups of five light emitters 41 are provided, and from the center side towards the two outer sides are light emitters 41a, 41b, 41c, 41d, and 41e respectively.

[0081] In addition, a light transmission suppression sheet 45 (light transmission suppression component) with a low light transmittance is pasted on the bottom wall 10 of the housing 8 so as to cover the light emitters 41. Thereby, it is difficult to distinguish the lit part when the light emitters 41 are not lit, and when lit in a bright environment, the visual difference from when not lit becomes significant, and it is easy to distinguish the situation that the light emitters 41 are lit. Therefore, the operator can more easily identify various states and information related to charging.

[0082] Next, the display method in the display unit 40 of the second embodiment will be described.

[0083] The display unit 40 changes the display method according to the following various states (1) to (5).

[0084] (1) When the cover is opened (guide display)

[0085] Similar to the first embodiment, when the charging port display control unit 25 inputs, via the lid opening / closing switch 26, that the lid 15 has been opened from the closed state, it lights up the light emitters 41a to 41b, 41c, 41d, 41e in this order from the central light emitter 41a. When the outermost light emitter 41e lights up, all the light emitters 41a to 41e light up. The light emitters 41a to 41e are all lit in white, and it takes, for example, 1.5 seconds to light up from the light emitter 41a to 41e. Then, all the light emitters 41a to 41e remain lit. In this way, when the lid is opened, a guiding display that lights up in an inward-to-outward expanding manner around the connector 5 is performed in the display unit 40. In addition, regarding the guiding display when the lid is opened, similar to the first embodiment, in addition to being sequentially switched from the extinguished state to the lit state, the illuminance (output) of the light emitters 20a to 20e can also be made to gradually increase from the inside to the outside to spread strong light.

[0086] (2) During connection standby

[0087] During the charging standby from when the above-mentioned guiding display when the lid is opened is performed until the charging plug is inserted into the connector 5, the light emitters 41a to 41e are lit one by one from the outside to the inside in white of the same color as when the lid is opened, for example, every 0.3 seconds, and all are lit for 0.5 seconds, and then all are extinguished for 0.5 seconds, and this operation is repeated until the charging plug is inserted.

[0088] (3) During charging

[0089] During charging, the charging port display control unit 25 changes the display mode in the display unit 40 according to the charging state (charging rate) of the vehicle's charging battery input from the charging control unit 30.

[0090] Among the multiple left and right light emitters 41a to 41e, the innermost light emitter 41a corresponds to a charging rate of 0 to 20%, the light emitter 41b corresponds to a charging rate of 21 to 40%, the light emitter 41c corresponds to a charging rate of 41 to 60%, the light emitter 41d corresponds to a charging rate of 61 to 80%, and the outermost light emitter 41e corresponds to 81 to 100%.

[0091] The charging port display control unit 25 performs action control so that the light emitter 41 corresponding to the charging rate during charging changes its color in the order of blue → white → blue, for example, every 0.5 seconds. The light emitter 41 closer to the inside than the light emitter 41 corresponding to the charging rate remains lit in blue, and the light emitter 41 closer to the outside than the light emitter 41 corresponding to the charging rate remains lit in white.

[0092] In addition, as another display example during charging, it is also possible to display all the light emitters 41 in such a way that the blue lighting flows from the outside to the inside, for example.

[0093] In addition, it is also possible to perform display in such a manner that the light emitters 41 corresponding to the charging rate and the light emitters 41 inside thereof cause blue display to flow from the outside to the inside.

[0094] (4) Charging completed

[0095] When the charging port display control unit 25 inputs the completion of charging of the charging battery from the charging control unit 30, it causes all of the light emitters 41a to 41e to light up in the same color (blue) as in the above (3) during charging. In addition, the charging completion is, for example, a range close to 100% of the charging rate (for example, the charging rate is 99 to 100%).

[0096] (5) Warning (insertion failure)

[0097] In the case of a relatively mild non-charging state such as a poor insertion of the charging plug into the connector 5, in the same manner as in the first embodiment, all of the light emitters 41a to 41e are caused to blink simultaneously at intervals of, for example, 0.5 seconds in a color different from the colors in the above (1) to (4) and in a color that draws attention (for example, yellow).

[0098] (6) Warning (charging system failure)

[0099] In the case of a relatively serious non-charging state such as a charging system failure, in the same manner as in the second embodiment, all of the light emitters 41a to 41e are caused to blink simultaneously at intervals of, for example, 0.5 seconds in a color different from the colors in the above (1) to (5) and in a color that draws more attention than in the case of (5) warning (for example, red).

[0100] As described above, the display unit 40 of the charging port display system 21 of the second embodiment has ten light emitters 41 (two groups of 41a to 41e). The ten light emitters 41 are arranged in the vicinity of the connector 5 in the same manner as in the first embodiment, emit light within the recess 9 that houses the connector 5, and when the opening operation of the lid 15 is detected, the light emission amounts of the plurality of light emitters 41 are changed to perform a guiding display that guides the line of sight to the connector 5. Therefore, it is possible to easily enable an operator around the vehicle to recognize the position of the power receiving unit 3 and the opening operation of the lid 15.

[0101] The light emitters 41 of the display unit 40 in the second embodiment are arranged on the bottom wall 10 which is the mounting surface of the connector 5, and are a plurality of left and right arc-shaped light emitters 41 (41a to 41e) arranged radially around the connector 5. Therefore, the position of the power receiving unit 3, particularly the connector 5, can be easily recognized by the light emission by the light emitters 41.

[0102] In addition, when the lid is opened, a guiding display is performed in which the light emitters 41 are sequentially lit in an order extending from the light emitter 41a closer to the connector 5 among the plurality of light emitters 41 to the light emitter 41e farther away. Therefore, for an operator who wants to charge and is near the vehicle, the visibility of the position of the connector 5 can be significantly improved in any case, especially at night and during the day.

[0103] During the connection standby after the guiding display, the following operation is repeated: the light emitters 41 are sequentially lit one by one from the light emitter 41a farther away from the connector 5 to the light emitter 41e closer to the connector 5 in the same color as the guiding display. Thereby, the visibility of the position of the connector 5 can also be improved during the connection standby, and the operator can recognize that it is in the connection standby.

[0104] In addition, during charging, the colors of the number of light emitters 41a to 41e corresponding to the charging rate of the vehicle's charging battery change between blue, which is different from that during the guiding display and connection standby, and white, which is used during the guiding display and connection standby. Thereby, the operator can recognize that it is in the charging state. In addition, since the number of light emitters whose colors change corresponding to the charging rate of the vehicle's charging battery is different, the operator can also easily recognize the charging rate. In addition, by changing the color between blue and white, the operator can perceptually recognize that the charging system is operating normally.

[0105] Moreover, by lighting all the light emitters 41 in the blue color used during charging when charging is completed, the operator can easily recognize that the charging has been completed.

[0106] Moreover, in the second embodiment, when charging cannot be performed due to a poor connection of the connector, all the light emitters 41 flash simultaneously in yellow, which is different from any of the displays during the guiding display, connection standby, charging, and charging completion. Therefore, the operator can easily recognize that charging cannot be performed.

[0107] In addition, in the second embodiment, when a failure occurs in the charging system, all the light emitters 41 flash simultaneously in red, which is different from that during the guiding display, connection standby, charging, charging completion, and when charging cannot be performed. Therefore, it is possible to easily recognize that charging cannot be performed and enable the operator to recognize a relatively serious abnormality.

[0108] The description of the embodiments is completed above, but the present utility model is not limited to the above embodiments. For example, the shapes of the display units 1 and 40 or the light emitters 20 and 41 in the above embodiments can be appropriately changed.
