In this case, when the user charges the storage battery 31 of the electric vehicle 30 and when the charging of the storage battery 31 of the electric vehicle 30 is completed, the user can charge the charging connector 11 and the charging cable 15 by the length of the distance L1 shown in FIG. Should be moved. The distance L1 is the distance between the holder 20 and the electric vehicle 30.

That is, when the user charges the storage battery 31 of the electric vehicle 30, the user sets the charging connector 11 at a position between the vehicle-side charging connection portion 32 of the electric vehicle 30 and the vehicle charging device 10. It may be moved from the electric vehicle to the electric vehicle 30. Further, when the charging of the storage battery 31 of the electric vehicle 30 is completed, the user is provided with the charging connector 11 at a position between the vehicle-side charging connection portion 32 of the electric vehicle 30 and the vehicle charging device 10. It may be moved from the holder 20 to the electric vehicle 30 and stored in the holder 20. Therefore, as compared with the case where the holder 20 is attached to the vehicle charging device 10, the user can charge the charging connector 11 when charging the storage battery 31 of the electric vehicle 30 and when the charging of the storage battery 31 of the electric vehicle 30 is completed. And the distance to handle the charging cable 15 is shortened. This reduces the workload of the user.

A large current is handled in charging the storage battery 31 of the electric vehicle 30. As described above, the charging connector 11 generally has a mass of, for example, about 1 kg. Further, the charging cable 15 has a mass of, for example, about 0.6 kg / m. Therefore, for example, when the length of the charging cable 15 is 6 m, the user needs to handle the charging cable 16 with a connector of about 4.6 kg. Here, for example, it is assumed that the charging connector 11 is housed in the vehicle charging device 10 when the storage battery 31 of the electric vehicle 30 is not charged.

When the distance between the vehicle-side charging connection portion 32 of the electric vehicle 30 and the vehicle charging device 10 is 6 m, the user needs to handle the 4.6 kg charging cable 16 with a connector for 6 m in order to charge the storage battery 31. There is. Further, even when the charging of the storage battery 31 is completed, the user needs to handle the 4.6 kg charging cable 16 with a connector for 6 m in order to store the charging cable 16 with a connector in the vehicle charging device 10. Therefore, the workload of the user when charging the storage battery 31 of the electric vehicle 30 is large.

On the other hand, in the vehicle charging system 1, the holder 20 can be attached to an attachment portion 40 provided at an arbitrary position between the vehicle side charging connection portion 32 of the electric vehicle 30 and the vehicle charging device 10. The charging cable 16 with a connector can be stored in the holder 20 at a position close to the electric vehicle 30. For example, the length of the charging cable 16 with a connector handled by the user by installing the holder 20 in the mounting portion 40 provided at the intermediate point between the vehicle-side charging connection portion 32 of the electric vehicle 30 and the vehicle charging device 10. Becomes 3m. In this case, the weight of the charging cable 16 with a connector handled by the user is only about 2.8 kg.

As a result, in the vehicle charging system 1, the work load on the user when charging the storage battery 31 of the electric vehicle 30 and when the charging of the storage battery 31 is completed is reduced. That is, since the length of the charging cable 15 handled by the user when the charging connector 11 is attached to and detached from the electric vehicle 30 is the length from the holder 20 to the electric vehicle 30, the work load on the user is reduced. This effect of reducing the work load of the user is particularly effective in reducing the physical burden on users with relatively weak strength such as women and the elderly. The mounting position of the holder 20 is preferably a position as close to the car as possible from the viewpoint of reducing the work load of the user.

Further, since the length of the charging cable 16 with a connector handled by the user becomes 3 m, the user can efficiently move the charging connector 11 from the holder 20 to the vehicle-side charging connection portion 32 of the electric vehicle 30 in a short time. Also, the charging connector 11 can be moved from the vehicle-side charging connection portion 32 of the electric vehicle 30 to the holder 20. Therefore, in the vehicle charging system 1 according to the first embodiment, the user's working time is shortened when the storage battery 31 of the electric vehicle 30 is charged and when the storage battery 31 is completely charged.

Further, when the user handles the charging connector 11 and the charging cable 15 for a long distance, the charging connector 11 and the charging cable 15 may be heavy and the user may drop the charging connector 11. If the charging connector 11 is dropped, a problem such as a failure or short circuit of the charging connector 11 due to deformation, cracking or breakage of the outer peripheral portion of the charging connection portion 13 may occur. Further, when the charging connector 11 is dropped, the charging connector 11 handles a large current, so that the charging connection portion 13a is provided with a plurality of electrical connection portions 13a due to deformation, cracking, or breakage. Problems such as poor contact, failure or short circuit of 13 may occur. Further, when the charging connector 11 is dropped, the charging connector 11 handles a large current, so that the lock mechanism 13b provided in the charging connection portion 13 cannot be locked or is not unlocked. Problems may occur. When these problems occur, there is a possibility that the storage battery 31 of the electric vehicle 30 cannot be charged.

In the vehicle charging system 1, since the distance for the user to handle the charging connector 11 and the charging cable 15 is shortened, the possibility that the user drops the charging connector 11 can be reduced. This makes it possible to reduce the occurrence of the above-mentioned problems caused by the user dropping the charging connector 11.

Further, in the electric vehicle 30, the position of the vehicle-side charging connection portion 32 when charging the storage battery 31 is determined to be one place for each vehicle type. For example, in a certain vehicle model, a vehicle-side charging connection portion 32 is provided on the front side of the vehicle. Further, in other vehicle types, the vehicle-side charging connection portion 32 is provided on the right side surface behind the vehicle. Therefore, after the vehicle charging device 10 is installed, the vehicle side of the electric vehicle 30 as seen from the vehicle charging device 10 is caused by a change in the vehicle type of the electric vehicle 30, a change in the parking direction of the electric vehicle 30, and the like. The position of the charging connection portion 32, the orientation of the vehicle-side charging connection portion 32 of the electric vehicle 30 as seen from the vehicle charging device 10, and the distance from the vehicle charging device 10 to the vehicle-side charging connection portion 32 of the electric vehicle 30 are changed. It is likely to be done.

In the vehicle charging system 1, the holder 20 is removable at an arbitrary position between the vehicle-side charging connection portion 32 of the electric vehicle 30 and the vehicle charging device 10. That is, in the vehicle charging system 1, the holder 20 can be installed at an arbitrary position between the vehicle-side charging connection portion 32 of the electric vehicle 30 and the vehicle charging device 10, and the vehicle-side charging connection of the electric vehicle 30 can be installed. It is possible to remove the holder 20 attached at an arbitrary position between the unit 32 and the vehicle charging device 10. That is, in the vehicle charging system 1, after the vehicle charging device 10 is installed, the mounting position of the holder 20 and the mounting direction of the holder 20 can be arbitrarily changed.

Therefore, in the vehicle charging system 1, the position of the vehicle-side charging connection portion 32 of the electric vehicle 30 as seen from the vehicle charging device 10 and the vehicle charging device 10 are changed after the vehicle charging device 10 is installed. The mounting position of the holder 20 and the holder 20 correspond to the orientation of the vehicle-side charging connection portion 32 of the electric vehicle 30 and the distance from the vehicle charging device 10 to the vehicle-side charging connection portion 32 of the electric vehicle 30. The mounting direction can be changed to a position where the user can easily handle the charging cable 16 with a connector. As a result, even if the vehicle type of the electric vehicle 30 or the parking direction of the electric vehicle 30 is changed after the vehicle charging device 10 is installed, the user can perform the work and charging connector for charging the storage battery 31 of the electric vehicle 30. The work of storing the 11 in the holder 20 can be efficiently performed.

Further, in the vehicle charging system 1, the charging connector 11 is housed in the holder 20 with the tip of the charging connecting portion 13 of the charging connector 11 facing diagonally downward, so that the tip of the charging connector 11 faces diagonally downward. The charging connector 11 can be stored in the posture. This makes it easier for the user to handle the charging connector 11 when the charging connector 11 is stored in the holder 20 and when the charging connector 11 is taken out from the holder 20, and the possibility of dropping the charging connector 11 is reduced. There is.

Further, in the holder 20, the charging connector 11 can be stored in the holder 20 simply by inserting the charging connection portion 13 of the charging connector 11 into the through hole 24 formed in the first connector holding portion 22a of the holder 20 from above. As a result, in the holder 20, it is easy to store the charging connector 11 and take out the charging connector 11, and the holder 20 is easy for the user to use.

Further, since the user performs the work of storing and taking out the charging connector 11 in front of the holder 20, it is necessary to secure the user's work space around the holder 20. In the holder 20, a connector holding portion 22 is provided below the charging cable winding portion 23. The charging cable winding portion 23 is provided in a region overlapping the connector holding portion 22 in the horizontal direction. That is, the holder 20 shares a space for holding the charging connector 11 and a space for holding the charging cable 15 in the horizontal direction.

As a result, the area of the holder 20 in the horizontal direction can be reduced, and the space for storing the charging cable 16 with a connector can be saved. That is, in the vehicle charging system 1, the holder 20 can be miniaturized, and the range of options for the installation location of the holder 20 is widened. Further, since the holder 20 can be miniaturized, it becomes easy to secure a work space around the holder 20 for the user to handle the charging cable 16 with a connector, and the range of options for the installation location of the holder 20 is wide. Become.

Further, the charging cable winding portion 23 serves as a barrier for drip-proofing and dust-proofing with respect to the connector holding portion 22 located at the lower part of the charging cable winding portion 23. As a result, in the holder 20, foreign matter such as water or dust that has fallen from above the connector holding portion 22 onto the connector holding portion 22 travels through the connector holding portion 22 and adheres to the charging connection portion 13 of the charging connector 11. It is possible to reduce the occurrence of short-circuit failure of the electrical connection portion 13a.

FIG. 8 is a cross-sectional view showing a modified example of the holder 20 shown in FIG. The first connector holding portion 22a may be provided parallel to the horizontal direction and at a right angle to the front side with respect to the fixing portion 21. That is, the first connector holding portion 22a may be provided perpendicular to the fixing portion 21 and parallel to the charging cable winding portion 23. In this case, the second connector holding portion 22b is not provided. Further, the distance L2 between the first connector holding portion 22a and the charging cable winding portion 23 is the charging connector 11 and the charging cable 15 when the charging connector 11 is stored in the holder 20 and when the charging connector 11 is taken out from the holder 20. Is a distance that does not come into contact with the charging cable winding portion 23.

When the holder 20 has the configuration shown in FIG. 8, the charging connector 11 can be stored in the holder 20 with the tip of the charging connection portion 13 of the charging connector 11 facing vertically downward. Since the charging connector 11 can be stored in a posture in which the tip portion of the charging connector 11 faces vertically downward, the charging connector 11 can be easily stored. Further, for example, when the position of the holder 20 is set to the height around the waist of the user, the charging connector 11 can be easily inserted into the through hole 24 when the user stores the charging connector 11 in the holder 20. As a result, the possibility that the user fails to insert the charging connector 11 into the through hole 24 and drops the charging connector 11 is reduced, and the workability of the user is improved. Further, when the user removes the charging connector 11 from the holder 20, the charging connector 11 can be easily taken out from the through hole 24, and the workability of the user is improved.

Further, in the above, the case where the charging cable winding portion 23 is provided at a right angle to the fixed portion 21 has been described, but the charging cable winding portion 23 is the same as the fixed portion 21 as seen from the fixed portion 21. The angle formed by the charging cable winding portion 23 may be an obtuse angle. As a result, when the charging cable 15 is wound around the charging cable winding portion 23, the charging cable 15 is less likely to fall off from the charging cable winding portion 23.

As described above, according to the first embodiment, the burden of handling work of the charging cable 16 with a connector generated by charging the storage battery 31 of the electric vehicle 30 can be reduced, and the storage battery 31 of the electric vehicle 30 can be charged. The work load of the accompanying user can be reduced. Further, according to the first embodiment, the miniaturization of the holder 20 makes it easier to secure a work space for the user around the holder 20.

As described above, in the holder 20a, the first side wall portion 25a and the second side wall portion 25b have a function of guiding the charge connection portion 13 to the through hole 24 when the charge connection portion 13 is housed in the holder 20a. As a result, in the holder 20a, the user can more easily store the charging connector 11 in the holder 20a, and the user can improve the workability of storing the charging connector 11.

Further, since the holder 20a has the first side wall portion 25a and the second side wall portion 25b on the side portion of the holder 20a, foreign matter such as water and dust flying from the side of the holder 20a can be collected from the charging connection portion of the charging connector 11. It is possible to prevent the entry into 13.

That is, the first side wall portion 25a and the second side wall portion 25b serve as a barrier for drip-proof against water flying from the side of the holder 20a with respect to the charging connector 11 and the connector holding portion 22. Thereby, in the holder 20a, it is possible to prevent water flying from the side of the holder 20a from entering the charging connection portion 13 of the charging connector 11 through the charging connector 11 or the connector holding portion 22.

Further, the first side wall portion 25a and the second side wall portion 25b serve as a barrier for dust protection against dust flying from the side of the holder 20a with respect to the charging connector 11 and the connector holding portion 22. Thereby, in the holder 20a, it is possible to prevent dust flying from the side of the holder 20a from entering the charging connection portion 13 of the charging connector 11 through the charging connector 11 or the connector holding portion 22.

As described above, since the charging connector 11 handles a large amount of electric power, when a foreign substance such as water or dust adheres to the electric connection portion 13a of the charging connection portion 13, a short-circuit failure of the electric connection portion 13a may occur. be. The holder 20a has the first side wall portion 25a and the second side wall portion 25b on the side portion of the holder 20a, so that a short-circuit failure of the electrical connection portion 13a caused by adhesion of foreign matter to the electrical connection portion 13a can occur.

Further, in the holder 20a, a second through hole 26b, which is a through hole 26, is formed in a corner portion formed by the first connector holding portion 22a, the second connector holding portion 22b, and the second side wall portion 25b. The lowermost portion of the holder 20a in which the through hole 26 is formed is a connection portion between the first connector holding portion 22a and the second connector holding portion 22b.

FIG. 12 is a diagram showing a discharge path of water droplets in the holder 20a shown in FIG. In FIG. 12, the moving path of water that has entered the box-shaped storage portion in which the charging connector 11 is stored is indicated by a broken line arrow. The holder 20a is provided with the side wall portion 25, so that the fixing portion 21, the first connector holding portion 22a, the second connector holding portion 22b, the first side wall portion 25a, the second side wall portion 25b, and the charging cable are provided. A box-shaped storage unit for storing the charging connector 11 is configured by the winding unit 23. In this case, if water has infiltrated into the side wall portion 25, that is, if water has infiltrated into the inside of the box-shaped storage portion, the water that has infiltrated into the inside of the box-shaped storage portion has a box shape. It tends to collect at the bottom of the storage section. In the holder 20a, the water that has entered the inside of the box-shaped storage portion flows to the lowermost part of the box-shaped storage portion by gravity, and is discharged to the outside of the box-shaped storage portion through the through hole 26. As a result, in the holder 20a, even if water enters the inside of the side wall portion 25, it is possible to prevent water from accumulating in the lower portion of the box-shaped storage portion.

Since the holder 20a can prevent water from accumulating in the lower part of the box-shaped storage part, for example, when the holder 20a is made of a rust-prone material such as iron, the water accumulated in the lower part of the box-shaped storage part. It is possible to prevent the holder 20a from rusting due to the above.

If dust has entered the inside of the side wall portion 25, that is, if dust has entered the inside of the box-shaped storage portion, the dust that has entered the inside of the box-shaped storage portion will be collected from the fixing portion 21. Even if it adheres to the first connector holding portion 22a, the second connector holding portion 22b, the first side wall portion 25a, the second side wall portion 25b, etc., the water that has entered the inside of the box-shaped storage portion flows as described above. When discharged from the through hole 26, it is discharged together with water. As a result, in the holder 20a, it is possible to prevent dust from accumulating on the lower portion of the box-shaped storage portion.

The charging connector 11 handles a large amount of electric power, and when foreign matter such as water or dust adheres to the electrical connection portion 13a of the charging connection portion 13, a short-circuit failure of the electrical connection portion 13a may occur. In the holder 20a, since the through hole 26 is formed at the lowermost portion of the holder 20a, even if foreign matter such as water and dust intrudes into the inside of the box-shaped storage portion, water is formed in the lower portion of the box-shaped storage portion. It is possible to prevent foreign matter such as dust from accumulating, and it is possible to reduce the occurrence of a short-circuit failure of the electrical connection portion 13a due to the adhesion of the foreign matter to the electrical connection portion 13a.

Further, since the holder 20a can prevent foreign substances such as water and dust from accumulating in the lower part of the box-shaped storage portion, the holder 20a can be kept clean.

In the second embodiment, the through holes 26 are formed at two corners of the box-shaped storage portion, but even if the entire lowermost portion of the box-shaped storage portion is a through hole. good. Specifically, the through hole 26 may be formed in the entire portion where the first connector holding portion 22a and the second connector holding portion 22b are connected. In this case, the first connector holding portion 22a and the second connector holding portion 22b are connected via the side wall portion 25.

Further, the position where the through hole 26 is formed, the shape of the through hole 26, and the number of the through holes 26 are not particularly limited as long as foreign substances such as water and dust can be discharged from the inside of the box-shaped storage portion as described above.

The holder 20a according to the second embodiment described above has the same effect as the holder 20 according to the first embodiment.

Further, since the holder 20a has the first side wall portion 25a and the second side wall portion 25b on the side portion of the holder 20a, foreign matter such as water and dust flying from the side of the holder 20a adheres to the electrical connection portion 13a. It is possible to reduce the occurrence of a short-circuit failure of the electrical connection portion 13a caused by the above. Further, since the holder 20a has a through hole 26 formed at the lowermost portion of the holder 20a, it is possible to prevent foreign substances such as water and dust from accumulating in the lower portion of the box-shaped storage portion, so that the holder 20a can be connected to the electrical connection portion 13a. It is possible to reduce the occurrence of short-circuit failure of the electrical connection portion 13a due to the adhesion of foreign matter.

Embodiment 3.
FIG. 13 is a front view of the holder 20b according to the third embodiment. 14 and 15 are front views showing a method of fixing the holder 20b shown in FIG. 13 to the mounting portion 40. FIG. 14 shows a state in which the screw 50 is temporarily tightened. FIG. 15 shows a state in which the screw 50 is fully tightened.

The difference between the holder 20b according to the third embodiment and the holder 20a according to the second embodiment described above is that the two screw fixing holes 21a formed in the upper region of the fixing portion 21 are the Dharma holes 21b. That is the point. Hereinafter, the points that the holder 20b is different from the holder 20a will be described. In FIGS. 13 to 15, the holder 20b has the same reference numerals as the holder 20a for the same configuration as the holder 20a, and detailed description thereof will be omitted.

The holder 20b is fixed to the mounting portion 40 by screw fixing, similarly to the holder 20a according to the second embodiment. In the holder 20b, two screw fixing holes 21a used when screwed to the mounting portion 40 are formed in a region on the lower side of the fixing portion 21. Further, the holder 20b has two Dharma holes 21b formed in the upper region of the fixing portion 21 as two screw fixing holes 21a used when the holder 20b is screwed and fixed to the mounting portion 40.

The Dharma hole 21b has a round hole shape as the opening shape of the two large and small openings. The round hole portion having a large opening in the Dharma hole 21b has a dimension larger than the maximum outer diameter portion of the screw 50 in the direction perpendicular to the axial direction of the screw 50. The round hole portion having a small opening in the Dharma hole 21b has the same dimensions as the screw fixing hole 21a, which is smaller than the maximum outer diameter portion of the screw 50 in the direction perpendicular to the axial direction of the screw 50. The Dharma hole 21b is formed with a round hole portion having a small opening on the upper side and a round hole portion having a large opening on the lower side. The round hole with a small opening is the first hole to which the screw 50 is fixed. Further, the round hole having a large opening is a second hole that is larger than the first hole and has an opening size through which the screw 50 can pass. Therefore, in the Dharma hole 21b, the first hole to which the screw 50 is fixed and the second hole having an opening size larger than the first hole through which the screw can pass are arranged side by side so as to partially overlap each other. It can be said that it is a formed hole.

When attaching the holder 20b to the mounting portion 40, first, as shown in FIG. 14, the screw 50 is temporarily tightened, and the round hole portion having a large opening in the two Dharma holes 21b is inserted into the temporarily tightened screw 50. Will be done. Next, the holder 20b is moved in the direction of the arrow shown in FIG. 15, that is, vertically downward. As a result, the small round hole portion of the opening of the Dharma hole 21b can be caught in the two temporarily tightened screws 50.

Next, the two temporarily tightened screws 50 are finally tightened, and the screws 50 are finally tightened to the two screw fixing holes 21a formed in the lower region of the fixing portion 21, so that the holder 20b is attached to the mounting portion. It is screwed to 40. At this time, the small round hole portion of the opening of the Dharma hole 21b is caught in the two temporarily tightened screws 50. Therefore, the operator does not need to manually support the holder 20b when the screw 50 is finally tightened, and the screw 50 is easily tightened.

Further, when the holder 20b is removed from the mounting portion 40, the Dharma hole 21b is provided with the screw 50 fully tightened in the two screw fixing holes 21a formed in the lower region of the fixing portion 21. The screw 50 that is finally tightened is loosened. As a result, the two screws 50 can be caught in the small round hole portion of the opening of the holder 20b. Next, the holder 20b is moved in the direction opposite to the direction of the arrow shown in FIG. 15, that is, vertically upward. As a result, the holder 20b is removed from the mounting portion 40 by moving the holder 20b toward the front side while passing the loosened screw 50 through the round hole portion having a large opening of the Dharma hole 21b.

That is, the operator loosens the two upper screws 50 screwing the holder 20b with the lower two screws 50 screwing the holder 20b removed, and raises the holder 20b upward. The holder 20b can be easily removed from the mounting portion 40 by pulling it toward you. As a result, the holder 20b can remove the holder 20b from the mounting portion 40 without removing all the screws 50.

As described above, when the holder 20b is attached / detached to / from the attachment portion 40, the holder 20b can be operated in a state where the holder 20b is caught by the two upper screws 50, so that the workability of attachment / detachment to / from the attachment portion 40 is improved. do. Further, since the holder 20b can be operated in a state where the holder 20b is caught by the two upper screws 50 when the holder 20b is attached to and detached from the mounting portion 40, there is no risk of the holder 20b being dropped unexpectedly, and the holder 20b is dropped.

It is assumed that 30 is parked on the left side of the vehicle charging device 10. In this case, the holder 20f is located between the vehicle charging device 10 and the electric vehicle 30. In this case, the distance at which the user moves the charging connector 11 to the electric vehicle 30 in order to charge the storage battery 31 of the electric vehicle 30 is defined as the distance L4. The distance L4 can be rephrased as the distance at which the charging connector 11 is moved to the holder 20f after the charging of the storage battery 31 of the electric vehicle 30 is completed.

Comparing the distance L3 and the distance L4, the distance L4 is shorter than the distance L3. Therefore, the load of the user's work is lighter in the case of the condition shown in FIG. 32 than in the case of the condition shown in FIG. 31. Therefore, when the electric vehicle 30 is parked on the left side of the vehicle charging device 10, it is preferable that the holder 20f is attached to the left side surface 18d of the housing 18 of the vehicle charging device 10.
