They are stored in the storage shelf 50 with the sides aligned in the same direction. Along with this, the clearance α on the side where the plug-in connector 21 is provided is designed so that the charging lid 32 will not interfere with the carrier 40 or other structures in anticipation that the charging lid 32 will be opened during charging. It is set wider than the clearance β on the side where the plug connector 21 is not provided. A dummy plug-in connector 22 is provided at a point-symmetrical position on the pallet 20 with respect to the plug-in connector 21 with respect to the center O of the pallet. The dummy plug-in connector 22 is the same as the plug-in connector 21 only in appearance and does not have a charging function. Further, the floor plate 12 of the storage section 10 is formed with an opening 13 for accommodating the pallet 20 and notches 14 and 15 for accommodating the plug-in connector 21 and the dummy plug-in connector 22 . A charging cord 23 is connected to the plug connector 21 . Incidentally, the charging port 31 of the electric vehicle 30 is not necessarily provided on one side in the width direction, but may be provided on one side in the front-rear direction.

The first sensor 60 has a first charging side sensor 61 and a first non-charging side sensor 62 . As shown in FIG. 1, the first charging side sensor 61 detects whether or not one widthwise side (the side where the charging port cover 32 is opened) of the stored electric vehicle 30 is within the transfer storage allowable area. It is arranged on one side in the width direction of the storage section 10 . The first non-charging side sensor 62 makes a pair with the first charging side sensor 61 and determines whether the other side in the width direction (the side without the charging port 31) of the electric vehicle 30 to be stored is within the transfer storage allowable area. It is disposed on the other side in the width direction of the storage section 10 so as to detect whether or not. The location of the first charging side sensor 61 is shifted to the right side as shown in FIG. 1 so that the transfer/storage allowable area is set wider than the opposite side in anticipation of the opening of the charging port 32 . 1 and 2, the first charging side sensor 61 and the first non-charging side sensor 62 of the first sensor 60 shown in FIGS. A laser sensor may be employed in which light receivers 61b and 62b for receiving the laser beams projected from the light projectors 61a and 62a and converting them into electric signals are disposed facing each other. However, the first charging side sensor 61 and the first non-charging side sensor 62 are not limited to laser sensors, and may be scanning type side area sensors capable of outputting physical shape data of space, or other sensors. A sensor of the form of can also be employed.

The second sensor 70 has a second charging side sensor 71 and a second non-charging side sensor 72 . As shown in FIG. 2, the second charging side sensor 71 detects whether or not the other side in the width direction of the electric vehicle 30 to be stored (the side where the charging port cover 32 is opened) is within the transfer storage allowable area. It is disposed on the other widthwise side of the storage section 10 . The second non-charging side sensor 72 makes a pair with the second charging side sensor 71 and determines whether the other side in the width direction (the side without the charging port 31) of the electric vehicle 30 to be stored is within the transfer storage allowable area. It is disposed on one side in the width direction of the warehousing section 10 so as to detect whether or not. The position of the second charging side sensor 71 is shifted to the left side as shown in FIG. 2 so that the transfer/storage allowable area is set wider than the opposite side in anticipation of the opening of the charging lid 32 . The second charging side sensor 71 and the second non-charging side sensor 72 of the second sensor 70 shown in FIGS. Similar to the sensor 62, there are light projectors 71a and 72a that incorporate light sources and project laser beams serving as detection media, and light receivers 71b and 72b that receive the laser beams projected from the light projectors 71a and 72a and convert them into electrical signals. can be adopted. However, the second charging side sensor 71 and the second non-charging side sensor 72 are not limited to laser sensors, and may be scanning type side area sensors capable of outputting physical shape data of space, or other sensors. can be employed.

1 or 2 based on the registered information as to which side in the width direction of the storage section 10 the charging port 31 of the electric vehicle 30 to be stored uses the plug-in connector 21 . As described above, the pallet 20 is called to the storage unit 10 so that the charging port 31 and the plug connector 21 of the electric vehicle 30 to be stored are located on the same side, and either the first sensor 60 or the second sensor 70 is detected. is selected to switch. Regarding the registration of which side in the width direction the charging port 31 of the electric vehicle 30 to be parked is provided, for example, on the screen of the operation panel of the mechanical parking device, as shown in FIGS. Please select the position of the charging port 31." Selection is made by pressing a button. However, in the case of condominiums and other collective housing, the user concludes a contract with the administrator to use the mechanical parking system. It is also possible for an administrator to acquire information as to which side in the width direction it is provided and input it to the control device 80 . Further, in the case where the charging port 31 of the electric vehicle 30 is provided not on one side in the width direction but on one side in the front-rear direction, the user can insert the connector 21 on either side in the width direction of the parking section 10 when entering the vehicle. Alternatively, it is sufficient to inform the manager in advance of which side the plug connector 21 is to be used at the time of making a contract.

The alarm device 90 is controlled by the control device 80 based on the detection result of either the first sensor 60 or the second sensor 70 that has been selected and switched so that the electric vehicle 30 is transported and stored on at least one side in the width direction. An alarm is issued when it is determined that the value is not within the allowable range.

On the other hand, as shown in FIG. 3, the method for detecting whether or not an electric vehicle can be parked in a mechanical parking system according to the present embodiment includes a registration step, a pallet calling step, a shift step, and a judgment step, and further includes a parking permitting step. , and a refusal step.

The registration step is a step of registering which side in the width direction of the storage section 10 the electric vehicle 30 to be stored uses the plug-in connector 21 (see step S10 in FIG. 3).

The pallet calling process is based on the information registered in the registration process, as shown in FIG. 1 or FIG. This is a step of calling the pallet 20 to the warehousing section 10 so as to do so (see step S20 in FIG. 3).

The shift step is a step of setting the transfer storage allowable area on the side registered in the registration step to be wider than the transfer storage allowable area on the unregistered side (see step S30 in FIG. 3).

The determination step is a step of determining whether or not the electric vehicle 30 is accommodated in the transfer/storage allowable areas on both sides in the width direction set in the shift step (see step S40 in FIG. 3).

The warehousing permission step is a step of permitting warehousing when it is determined in the determination step that the electric vehicle 30 is within the transfer storage allowable regions on both sides in the width direction (see step S50 in FIG. 3).

The step of refusing to enter the vehicle is a step of issuing an alarm when it is determined in the determination step that the electric vehicle 30 does not fit within the transfer/storage allowable area on at least one side in the width direction (see step S60 in FIG. 3).

Next, the operation of the above embodiment will be described.

When the user puts the electric vehicle 30 into the mechanical parking system, first, it is registered which side of the parking unit 10 in the width direction the insertion connector 21 is to be used for the electric vehicle 30 ( (see step S10 in FIG. 3). This is the registration process.

When the charging port 31 of the electric vehicle 30 to be parked is provided on the right side in the width direction, the user, as shown in FIG. Please select a position.”, press the “R” button. However, in the case of a mechanical parking device for a collective housing such as a condominium, the manager obtains information on which side in the width direction the charging port 31 is provided at the time of contract and inputs it into the control device 80 in advance. , the user does not need to register every time he/she enters the warehouse. Further, when the charging port 31 of the electric vehicle 30 is provided not on one side in the width direction but on one side in the front-rear direction, the user can insert the connector 21 on either side in the width direction of the parking section 10 when entering the vehicle. or to inform the administrator of the side to use the plug-in connector 21 in advance at the time of making a contract.

Based on the information registered in the registration process, as shown in FIG. 10, the palette 20 is called (see step S20 in FIG. 3). This is the pallet calling step.

When the pallet 20 is called to the storage section 10 , the door 11 is opened and the user moves the electric vehicle 30 onto the pallet 20 . After that, the user gets off the electric vehicle 30, and when charging is necessary, opens the charging port lid 32, connects one end of the charging cord 23 to the charging port 31, and inserts the other end of the charging cord 23. connected to the plug-in connector 21. When the connection is completed, the user exits from the mechanical parking device and performs a parking completion operation by pressing a parking button (not shown) on the control panel.

When the user performs the warehousing completion operation, the transfer storage allowable area on the side registered in the registration process is set wider than the transfer storage allowable area on the unregistered side (see step S30 in FIG. 3). This is the shift process. The shift process is performed by the control device 80 selecting and switching either the first sensor 60 or the second sensor 70 . In FIG. 1 , the first sensor 60 is selected because the charging port 31 of the electric vehicle 30 to be parked is provided on the right side in the width direction.

When the first sensor 60 is selected, the opened charging lid 32 is transferred and stored by the first charging side sensor 61 arranged on one side in the width direction of the storage section 10 (the right side in the example of FIG. 1). It is detected whether or not it is within the allowable area, and the first non-charging side sensor 62 arranged on the other side in the width direction of the storage part 10 (left side in the example of FIG. 1) detects It is detected whether the side is within the transport storage allowance area. That is, the control device 80 determines whether or not the electric vehicle 30 is accommodated in the transfer/storage allowable areas on both sides in the width direction set in the shift step (see step S40 in FIG. 3). This is the decision process.

If it is determined in the determination step that the electric vehicle 30 is within the transport and storage allowable areas on both sides in the width direction, warehousing is permitted (see step S50 in FIG. 3). This is the warehousing permission step. When the warehousing is permitted, the door 11 is closed, and the pallet 20 in the warehousing section 10 with the electric vehicle 30 mounted thereon is rotated clockwise as shown in FIG. It is turned by 90°, lifted (or lowered in the case of an underground type) by a carrier 40, laterally moved, and transported to a storage shelf 50. - 特許庁

On the other hand, if it is determined in the determination step that the electric vehicle 30 does not fit within the transfer/storage allowable area on at least one side in the width direction, the alarm device 90 issues an alarm (see step S60 in FIG. 3). ). This is the warehousing refusal step. If the entry is refused, the door 11 remains open and cannot be closed, and the user re-enters the interior of the mechanical parking device, closes the charging port cover 32, or places the electric vehicle 30 on the pallet 20. you can fix it. After that, the process returns to the determination step, and if it is determined that the electric vehicle 30 is within the transfer/storage allowable area on both sides in the width direction, the warehousing permission step is performed.

On the other hand, in the registration process, when the charging port 31 of the electric vehicle 30 to be parked is provided on the left side in the width direction, the user can see the display on the screen of the operation panel of the mechanical parking device as shown in FIG. In response to the message "Please select the position of the charging port 31", the "L" button is pressed. However, in the case of a mechanical parking device for a collective housing such as a condominium, the manager obtains information on which side in the width direction the charging port 31 is provided at the time of contract and inputs it into the control device 80 in advance. In addition, the user does not need to register each time he/she enters the warehouse, as described above. Further, when the charging port 31 of the electric vehicle 30 is provided not on one side in the width direction but on one side in the front-rear direction, the user may insert the plug-in connector 21 on either side in the width direction of the parking section 10 when entering the vehicle. Selecting whether or not to use the plug-in connector 21, or informing the administrator of the side to use the plug-in connector 21 in advance at the time of contract is the same as described above.

In the pallet calling process, based on the information registered in the registration process, as shown in FIG. The pallet 20 is called to the warehousing section 10 so as to be positioned at (see step S20 in FIG. 3).

When the pallet 20 is called to the storage section 10 , the door 11 is opened and the user moves the electric vehicle 30 onto the pallet 20 . After that, the user gets off the electric vehicle 30, and when charging is necessary, opens the charging port lid 32, connects one end of the charging cord 23 to the charging port 31, and inserts the other end of the charging cord 23. connected to the plug-in connector 21. When the connection is completed, the user exits from the mechanical parking device and performs a parking completion operation by pressing a parking button (not shown) on the control panel.

When the user performs the warehousing completion operation, as a shift process, the transfer storage allowable area on the side registered in the registration process is set wider than the transfer storage allowable area on the unregistered side (step S30 in FIG. 3). reference). In the shift process, as shown in FIG. 2, the charging port 31 of the electric vehicle 30 to be parked is provided on the left side in the width direction, so the control device 80 selects the second sensor 70 .

When the second sensor 70 is selected, the opened charging lid 32 is transported and stored by the second charging side sensor 71 arranged on the other widthwise side (the left side in the example of FIG. 2) of the storage section 10. It is detected whether or not it is within the allowable area, and the second non-charging side sensor 72 arranged on one side in the width direction of the storage part 10 (right side in the example of FIG. 2) detects It is detected whether the side is within the transport storage allowance area. That is, in the determination process, it is determined by the control device 80 whether or not the electric vehicle 30 is accommodated in the transfer/storage allowable areas on both sides in the width direction set in the shift process (see step S40 in FIG. 3).

When it is determined in the determination step that the electric vehicle 30 is within the transport and storage allowable regions on both sides in the width direction, as in the above-described warehousing permission step, warehousing is permitted (see step S50 in FIG. 3). . When the entry is permitted, the door 11 is closed, and the pallet 20 in the entry section 10 with the electric vehicle 30 mounted thereon is rotated counterclockwise as shown in FIG. 90°, is lifted (or lowered in the case of an underground type) by the carrier 40, laterally moved, and transported to the storage shelf 50.

On the other hand, if it is determined in the determination step that the electric vehicle 30 does not fit within the transfer/storage allowable area on at least one side in the width direction, the alarm device 90 issues an alarm as the step of refusing entry, as described above. (See step S60 in FIG. 3). If the entry is denied, the user can close the charging port 32 or place the electric vehicle 30 back on the pallet 20 . After that, the process returns to the determination step, and if it is determined that the electric vehicle 30 is within the transfer/storage allowable area on both sides in the width direction, the warehousing permission step is performed.

In this embodiment, unlike the inventions disclosed in Patent Documents 1 and 2, it is not necessary to change the shape of the pallet 20 itself.

Also, if the pallets 20 are stored in the storage shelf 50 without aligning the sides on which the plug connectors 21 are provided in the same direction, the charging port cover 32 that is opened during charging may not be attached to the carrier 40 or other structure. In order not to interfere with the pallets 20, it is necessary to set clearances α on both sides of the pallets 20 mounted on the carrier 40 and on both sides of the pallets 20 stored on the storage shelf 50, respectively. In this case, the width of the mechanical parking device (length in the vertical direction in FIGS. 1 and 2) must be widened by a total dimension corresponding to 2α×3=6α, and the volume of the mechanical parking device must be increased accordingly. also increases. However, in the case of this embodiment, the pallets 20 are stored in the storage shelf 50 with the sides on which the plug-in connectors 21 are provided aligned in the same direction. Thus, if there is a total dimension corresponding to α×3+β=3α+β<4α (because β<α), the charging port cover 32 opened during charging will not interfere with the carriage 40 or other structures, and the machine will not interfere. By narrowing the width of the parking system, it is possible to reduce the volume of the mechanical parking system accordingly.

Thus, the electric vehicle 30 can be stored smoothly and efficiently without changing the shape of the pallet 20 itself.

In the case of this embodiment, a dummy plug-in connector 22 is provided at a point-symmetrical position on the pallet 20 with respect to the plug-in connector 21 with respect to the center O of the pallet. With this configuration, as shown in FIG. is blocked by the dummy plug-in connector 22 . Further, as shown in FIG. 2, in a state in which the pallet 20 is accommodated in the opening 13 formed in the floor plate 12 of the storage section 10, the insertion connector 21 is accommodated in the notch 15, and the notch 14 is for the dummy insertion. It is blocked by the connector 22 . If the dummy plug-in connector 22 were not provided, the notch 15 would remain open when the plug-in connector 21 was accommodated in the notch 14 , and the plug-in connector 21 would be accommodated in the notch 15 . In this state, the notch 14 remains open. If the notch 15 and the notch 14 are left open, there is a possibility that the user may drop an object or have his/her foot tripped. However, in the case of the present embodiment, it is possible to avoid leaving the notch 15 and the notch 14 open, so that the user does not have to worry about dropping an object or tripping. Also, unlike the plug-in connector 21, the dummy plug-in connector 22 does not require any electrical parts or the like, and there is no need to worry about increased costs.

Further, in the case of this embodiment, the pallet 20 in the storage section 10 is rotated by 90° and conveyed to the storage rack 50. As shown in FIG. With this configuration, even if the insertion connector 21 of the pallet 20 is arranged on whichever side in the storage section 10 so as to correspond to the charging port 31 of the electric vehicle 30, as shown in FIG. If it is turned 90° or counterclockwise 90° as shown in FIG. This is effective in improving efficiency.

Furthermore, in the case of this embodiment, based on the detection result of either the first sensor 60 or the second sensor 70 selected and switched, the controller 80 controls the electric vehicle 30 to move to at least one side in the width direction. is provided with an alarm device 90 for issuing an alarm when it is determined that the transfer storage allowable area is not satisfied. By configuring in this way, the user can recognize that the warehousing has been refused by the alarm emitted from the alarm device 90, and can respond so that the warehousing is permitted.

On the other hand, in the present embodiment, the method for detecting whether or not an electric vehicle can be parked in a mechanical parking system that stores an electric vehicle 30 provided with a charging port 31 is such that the charging port 31 of the electric vehicle 30 to be parked is in the width direction of the parking section 10 . A registration process for registering on which side the plug-in connector 21 is to be used, and the plug-in connector 21 is registered with respect to the charging port 31 of the electric vehicle 30 to be stored based on the information registered in the registration process. A pallet calling process of calling the pallet 20 to the warehousing unit 10 so that it is located on the side of the warehousing unit 10, and a shift process of setting the transfer storage allowable area on the side registered in the registration process to be wider than the transfer storage allowable area on the unregistered side. and a judgment step of judging whether or not the electric vehicle 30 is accommodated in the transfer/storage allowable areas on both sides in the width direction set in the shift step. By performing the detection of whether or not the electric vehicle 30 can be stored in a manner that includes such a process, the electric vehicle 30 can be stored smoothly and efficiently without changing the shape of the pallet 20 itself.

Furthermore, in the method for detecting whether or not an electric vehicle can enter a parking space for a mechanical parking device according to the present embodiment, if it is determined in the determination step that the electric vehicle 30 is within the transfer/storage allowable areas on both sides in the width direction, the entrance is permitted. A warehousing permission process and a warehousing refusal process of issuing an alarm when it is determined in the determination process that the electric vehicle 30 is not within the transfer storage allowable area on at least one side in the width direction are included. In this way, if the entry permission step and the entry refusal step are further included to detect whether or not the electric vehicle 30 is allowed to enter the parking lot, the user can recognize whether entry is permitted or rejected, and an alarm is issued. If an entry is issued and entry is denied, it can be accommodated so that entry is permitted.

It should be noted that the mechanical parking system of the present invention and the method for detecting whether or not an electric vehicle can be parked in the mechanical parking system are not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention. It is of course possible to add
