[0011] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings.

[0012] <1. Overall configuration of the battery exchange system> 1 is a schematic perspective view for explaining the overall configuration of a battery exchange system according to an embodiment. The battery exchange system 100 exchanges a battery 11 of a vehicle 10. The vehicle 10 is, for example, a large vehicle such as a truck or a bus. The vehicle 10 is parked in front of the battery exchange system 100.

[0013] In the following description, the direction approaching the vehicle 10 from the battery exchange system 100 is defined as the X direction, the rear direction in the fore-and-aft direction of the vehicle is defined as the Y direction, and the up-and-down direction is defined as the Z direction. Note that, although the following description will be given of a case in which the battery exchange system 100 is disposed on only one side of the vehicle 10, the battery exchange system 100 may be disposed on both sides of the vehicle 10 so that the batteries 11 can be exchanged from both sides.

[0014] The battery exchange system 100 includes a container 110 that can be transported by a trailer, an accommodation unit 120 that accommodates the battery 11, a control unit 130, and a battery exchange device 200. The accommodation unit 120, the control unit 130, and the battery exchange device 200 are provided inside the container 110. Note that the control unit 130 is not limited to being placed inside the container 130, and may be placed outside the container 130.

[0015] The storage unit 120 is a shelf capable of storing a plurality of batteries 11 in the Y direction and the Z direction. A charging facility (not shown) is provided in the storage unit 120. The battery 11 stored in the storage unit 120 is charged by the charging facility.

[0016] The battery exchange device 200 removes the battery 11 mounted on the vehicle 10 from the vehicle 10 and stores it in a storage section 120, and also removes the charged battery 11 stored in the storage section 120 from the storage section 120 and attaches it to the vehicle 10.

[0017] The control unit 130 controls the battery exchange device 200 and the charging equipment.

[0018] When using the battery exchange device 200, the container 110 is lowered from the trailer bed to the ground using a crane or the like, and the door of the container 110 facing the vehicle 10 is opened.

[0019] <2. Battery exchange device configuration> FIG. 2 is a perspective view showing the overall configuration of the battery exchange device 200. As shown in FIG.

[0020] The battery exchange apparatus 200 has a traveling frame 210, a traveling rail 211, a first lifting frame 220, and a revolving frame 230. The traveling frame 210 moves in the ±Y directions along the traveling rail 211 by the driving force of a traveling actuator 212.

[0021] The first lifting frame 220 is provided in an internal space covered by the traveling frame 210 , and moves in the ±Z directions along the lifting rails 221 by the driving force of a first lifting actuator 222 .

[0022] The swivel frame 230 is provided in an internal space covered by the first lift frame 220, and swivels (rotates) about the Z direction as a rotation axis by the driving force of a swivel actuator 232 (FIG. 4) described later.

[0023] When the battery 11 is mounted on the vehicle 10, it is held by a battery bracket 20. The battery bracket 20 is fixed to the vehicle 10 and has the function of positioning and holding the battery 10 at a predetermined battery mounting position, as well as the function of guiding the battery 10 to a pull-out position, which will be described later.

[0024] Fig. 3 is a perspective view showing a detailed configuration of a mechanism provided in the internal space of the revolving frame 230. Fig. 4 is a perspective view showing the position of each actuator.

[0025] A first slide frame 240, a second lift frame 250, and a battery holding arm 260 are provided in the internal space of the revolving frame 230. The battery holding arm 260 may also be called a second slide frame.

[0026] The first slide frame 240 is slidably supported by a slide rail 241 fixed to the swivel frame 230 , and moves in the ±X directions by the driving force of a first slide actuator 242 .

[0027] The second lift frame 250 is supported on a guide rail 251 fixed to the first slide frame 240 so as to be able to freely rise and fall, and moves in the ±Z directions by the driving force of a second lift actuator 252 .

[0028] The battery holding arm 260 is slidably supported by a slide rail 261 fixed to the second lift frame 250, and moves in the ±X directions by the driving force of a battery holding arm actuator 262.

[0029] The battery holding arm 260 has a mounting portion 260a on which the battery 11 is mounted, and a pushing portion 260b that pushes the battery 11 in the direction of the vehicle 10. The mounting surface of the mounting portion 260a and the pushing surface of the pushing portion 260b are perpendicular to each other, and the battery holding arm 260 has a roughly L-shaped general shape when viewed from the ±Y direction.

[0030] The push-out section 260b is provided with a battery position detection camera 271 and a battery detection limit switch 272. An image obtained by the battery position detection camera 271 is sent to the control unit 130, and the control unit 130 controls the Y and Z directions of each member that moves the battery holding arm 260 based on this image. This allows the battery holding arm 260 to accurately access the position where the battery 11 is mounted, and controls the X direction position by the battery detection limit switch 272. In addition, the control unit 130 attaches a replacement battery 11 to the vehicle 10 based on position information of the battery 11 when it was removed from the vehicle 10.

[0031] The battery detection limit switch 271 has a lever that is pressed in by the side of the battery 11 when the battery 11 is placed in a predetermined position on the battery holding arm 260. The battery detection limit switch 271 detects whether the battery 11 is placed in a predetermined position on the battery holding arm 260 based on the state of this lever, and sends the detection result to the control unit 130. The control unit 130 switches the operation of each member that moves the battery holding arm 260 based on this detection result.

[0032] <3. Battery exchange device operation> Next, the operation of the battery exchange device 200 will be described.

[0033] First, as shown in FIG. 5, the battery exchange device 200 moves the traveling frame 210 in the Y direction so that the battery holding arm 260 is positioned in front of the battery 11.

[0034] Furthermore, the battery exchange apparatus 200 lowers the first lifting frame 220 to the lowest position. Note that the position of the first lifting frame 220 does not necessarily have to be the lowest position, and it may be moved to a vertical position according to the position of the battery 11.

[0035] Next, the battery exchange device 200 moves the first slide frame 240 toward the battery 11 (+X direction). This movement toward the battery 11 is performed at least until the position of the second lift frame 250 in the X direction protrudes outside the container 110.

[0036] 6, the battery exchange apparatus 200 lowers the second lifting frame 250. This lowering of the second lifting frame 250 is performed at least until the portion of the battery holding arm 260 that holds the battery 11 is positioned lower than the bottom surface of the battery 11.

[0037] Next, as shown in FIG. 7, the battery exchange apparatus 200 moves the battery holding arm 260 toward the battery 11 (+X direction).

[0038] Next, as shown in Fig. 8, the battery exchange apparatus 200 moves the battery holding arm 260 in the -X direction while the battery 11 is held by the battery holding arm 260. Here, before reaching the state shown in Fig. 8, the battery exchange apparatus 200 first slightly raises the second lifting frame 250 from the state shown in Fig. 7. The raised position at this time is a position where the locking claws 263 formed on the battery holding arm 260 lock onto the battery 11, but the battery 11 cannot be lifted by the battery holding arm 260. By moving the battery holding arm 260 in the -X direction while the locking claws 263 are locked onto the battery 11 in this way, the state shown in Fig. 8 is reached.

[0039] In the state shown in Fig. 8, the battery 11 is pulled out to the side of the vehicle 10. In other words, Fig. 8 shows a state in which the vehicle body is not present above the battery 11.

[0040] The locking claws 263 are formed at positions corresponding to the four corners of the battery 11. The locking claws 263 are provided at the four corners so as to regulate the position of the battery 11 in the X and Y directions, and consist of a total of eight claws. When the battery 11 is held by the battery holding arm 260, the locking claws 263 prevent the battery 11 from shifting in the X and Y directions.

[0041] 9, the battery exchange apparatus 200 raises the second lifting frame 250. As a result, the battery 11 moves away from the mounting base 22 of the battery bracket 20.

[0042] The battery bracket 20 has a mounting base 22 and slide rails 21 that support the mounting base 22 so that it can slide freely in the ±X directions. In addition, a positioning pin 23 is provided on the mounting base 22. A hole (not shown) into which the positioning pin 23 fits is formed in the underside of the battery 11, so that when the battery 11 is placed on the mounting base 22, the battery 11 is positioned with high accuracy and damage to the terminals due to misalignment of the battery 11 can be prevented.

[0043] Next, as shown in FIG. 10, the battery exchange apparatus 200 moves the first slide frame 240 in the −X direction until the battery 11 is located within the swivel frame 230.

[0044] Next, as shown in FIG. 11, the battery exchange device 200 rotates (turns) the swivel frame 230. By rotating the swivel frame 230 180 degrees, the battery 11 faces the storage section 120. Simultaneously with the rotation of the swivel frame 230, the traveling frame 210 and the first lifting frame 220 are moved to move the battery 11 to a desired storage position in the storage section 120. Next, the first slide frame 240, the second lifting frame 250, and the battery holding arm 260 are moved to store the battery 11 in a predetermined position in the storage section 120. Note that the operation when storing the battery 11 can be changed as appropriate depending on the configuration of the storage section 120, and is not particularly limited in the present disclosure.

[0045] The above describes the operations performed when removing the battery 11 from the vehicle 10. When installing the battery 11 in the vehicle 10, the operations performed when removing the battery 11 are essentially reversed.

[0046] To explain briefly, first, the battery exchange device 200 removes the charged battery 11 from the storage section 120. Next, the battery exchange device 200 turns the turning frame 230 and moves the traveling frame 210 and the first lifting frame 220, thereby reaching the state shown in FIG.

[0047] Next, the state of the battery exchange device 200 transitions from FIG. 9 to FIG. 8, and the battery 11 is placed on the placement stand 22. At this time, the battery 11 is positioned by the positioning pin 23 and locked by the locking claw 263.

[0048] In this state, when the battery holding arm 260 moves in the +X direction, the battery 11 is pushed out by the pushing portion 260b of the battery holding arm 260, and the position of the battery 11 transitions from Figure 8 to Figure 7. In the state of Figure 7, the battery 11 is electrically connected to the vehicle.

[0049] <4. Summary> As described above, the battery exchange system and battery exchange device of the present disclosure have the following configuration.

[0050] (1) One aspect of the battery exchange system of the present disclosure is a battery exchange system 100 that replaces a battery 11 mounted on a vehicle 10, the vehicle 10 having a bracket 20 that holds the battery 11, and a battery exchange device 200 having an arm (battery holding arm 260) that holds the battery 11 and an arm moving unit that moves the arm (battery holding arm 260), the arm moving unit having at least a first lifting unit (first lifting frame 220) that moves the arm (battery holding arm 260) in the vertical direction within the device body of the battery exchange device 200, and a second lifting unit (second lifting frame 250) that moves the arm (battery holding arm 260) in the vertical direction outside the device body.

[0051] In this way, by sharing the lifting and lowering operation of the arm (battery holding arm 260) between the first lifting section (first lifting frame 220) and the second lifting section (second lifting frame 250), a battery exchange system 100 can be realized in which the battery 11 can be removed and installed quickly and with high reliability.

[0052] That is, access to the storage section 120 is performed by the first lifting section (first lifting frame 220), and access to the battery 11 mounted on the vehicle 10 is performed by the second lifting section (second lifting frame 250), so that the battery 11 mounted on the vehicle 10 can be lifted from below by the second lifting section (second lifting frame 250), removed, and moved, even if the position of the vehicle 10 is not higher than that of the battery exchange device 200. As a result, compared to the case where the battery 11 is grasped from above and moved, for example, it is possible to prevent the battery 11 from falling off, etc., and to move it quickly with improved reliability.

[0053] Fig. 12 is a side view showing the vertical positional relationship between the battery 11 mounted on the vehicle 10 and the battery exchange apparatus 200. As shown in Fig. 12, in the battery exchange apparatus 200 of this embodiment, even if the position of the bottom surface of the battery 11 is lower than the installation position of the battery exchange apparatus 200, the arm (battery holding arm 260) can be lowered to a position lower than the bottom surface of the battery 11 by the second lifting section (second lifting frame 250). As a result, even if the vehicle 10 is on the ground at the same height as the battery exchange apparatus 200, for example, it becomes possible to lift up the battery 11, remove it, and move it. In other words, a device for jacking up the vehicle 10 or a slope is not required.

[0054] Furthermore, because the lifting and lowering operation is performed in two stages, the size of the arms when retracted can be reduced, making it easier to store the first lifting and lowering section and the second lifting and lowering section within the device body.

[0055] (2) In one aspect of the battery exchange system disclosed herein, the arm and arm moving section at least include a first slide section (first slide frame 240) that moves the arm in a direction (±X direction) toward and away from the battery 11 mounted on the vehicle 10 in an area including within the device body of the battery exchange device 200, and a second slide section (battery holding arm 260) that moves the arm in a direction (±X direction) toward and away from the battery 11 mounted on the vehicle 10 in an area outside the device body.

[0056] This allows the sliding movement in the ±X directions to occur in two stages, so that the size of the arm in its retracted state can be reduced, making it easier to store the first sliding portion and the second sliding portion within the device body.

[0057] (3) In one aspect of the battery exchange system of the present disclosure, the arm includes a mounting portion 260a for mounting the battery 11 thereon, and a pushing portion 260b for pushing the battery 11 toward the vehicle 10 (+X direction).

[0058] (4) In one embodiment of the battery exchange system disclosed herein, when removing the battery 11 from the vehicle 10, the arm moving unit moves the arm below the battery 11 held by the bracket 20, and then raises the arm to place the battery 11 on the mounting portion 260a and pulls the battery 11 into the device main body; when attaching the battery 11 to the vehicle 10, the arm moving unit moves the battery 11 removed from the storage portion 120 that houses the battery 11, outside the device main body, and then lowers the arm to move the battery 11 onto the bracket 20. The push-out portion 260b pushes the battery 11 in the direction of the vehicle 10 (+X direction) to move the battery 11 to the electrical connection position.

[0059] (5) In one embodiment of the battery exchange system of the present disclosure, the bracket 20 includes a bracket mounting portion 22 for mounting the battery 11, and a support portion (slide rail 21) for supporting the bracket mounting portion 22 so that the bracket mounting portion 22 can slide between the electrical connection position of the battery 11 in the vehicle 10 and a battery pull-out position on the side of the vehicle 10.

[0060] This allows the battery 11 to be positioned at a predetermined battery connection position with high accuracy when installing the replaced battery 11. As a result, damage to the terminals caused by misalignment of the battery 11 can be prevented.

[0061] (6) In one aspect of the battery exchange system of the present disclosure, a locking portion (locking claw 263) for locking the battery 11 is formed on the mounting portion 260a of the arm (battery holding arm 260).

[0062] This makes it possible to prevent the battery 11 from falling off the mounting portion 260a or from becoming displaced.

[0063] (7) In one aspect of the battery exchange system of the present disclosure, the mounting portion 260a of the bracket 20 is formed with a positioning pin 23 for positioning the mounted battery 11 at an electrical connection position.

[0064] This allows the battery 11 to be guided to the correct electrical connection position, and prevents damage to the terminals due to misalignment of the electrical connection position.

[0065] (8) In one embodiment of the battery exchange system of the present disclosure, the battery exchange apparatus 200 is provided within a container 110 that can be transported by a trailer.

[0066] This makes it possible to construct the battery exchange system 100 without constructing a fixed battery exchange station, simply by transporting and installing the container 110. As a result, capital investment can be significantly reduced.

[0067] (9) In one aspect of the battery exchange system of the present disclosure, the container 110 further includes a storage section 120, a charging / discharging equipment for charging the battery 11 stored in the storage section 120, and a control unit 130 for controlling the battery exchange device 200 and the charging equipment.

[0068] (10) One embodiment of the battery exchange device disclosed herein comprises an arm (battery holding arm 260) that holds a battery 11, and an arm moving unit that moves the arm (battery holding arm 260). The arm moving unit comprises at least a first lifting unit (first lifting frame 220) that moves the arm (battery holding arm 260) in the vertical direction within the main body of the battery exchange device 200, and a second lifting unit (second lifting frame 250) that moves the arm (battery holding arm 260) in the vertical direction outside the main body of the battery exchange device.

[0069] (11) In one aspect of the battery exchange device disclosed herein, the arm and arm moving section include at least a first slide section (first slide frame 240) that moves the arm in a direction (±X direction) toward and away from the battery 11 mounted on the vehicle 10 in an area including within the device body of the battery exchange device 200, and a second slide section (battery holding arm 260) that moves the arm in a direction (±X direction) toward and away from the battery 11 mounted on the vehicle 10 in an area outside the device body.

[0070] (12) In one aspect of the battery exchange device of the present disclosure, the arm includes a placement portion 260a for placing the battery 11 thereon, and a push-out portion 260b for pushing the battery 11 in the direction of the vehicle 10 (+X direction).

[0071] (13) In one aspect of the battery exchange device of the present disclosure, a locking portion (locking claw 263) for locking the battery 11 is formed on the mounting portion 260a of the arm (battery holding arm 260).

[0072] (14) One embodiment of the battery exchange apparatus of the present disclosure is mounted within a container 110 that can be transported by a trailer.

[0073] (15) One aspect of the battery exchange system disclosed herein includes a plurality of the battery exchange devices 200, and when replacing batteries of the same vehicle, while the arm of a first battery exchange device 200 is performing the operation of removing the battery 11 from the vehicle 10, the arm of a second battery exchange device 200 is performing the operation of removing the battery 11 from the battery storage section 120.

[0074] This makes it possible to realize a battery exchange system that allows the battery 11 to be replaced more quickly.

[0075] The above-described embodiment is merely an example of the embodiment of the present invention, and the technical scope of the present invention should not be interpreted as being limited by the embodiment. In other words, the present invention can be embodied in various forms without departing from the gist or main characteristics of the present invention.

[0076] In the above embodiment, the battery exchange device 200 is used in a state where the container 110 is lowered from the bed of the trailer to the ground by a crane or the like as shown in Fig. 1, but the battery exchange device 200 may be used with the container 110 remaining loaded on the bed 300 of the trailer as shown in Fig. 13 in which the same reference numerals are used for parts corresponding to those in Fig. 1. In this way, battery exchange can be performed more easily.

[0077] In addition to the above-described embodiment, the container 110 may be provided with a solar panel (not shown) and the battery 11 in the storage section 120 may be charged with electricity generated by the solar panel. The container 110 may be expanded in the longitudinal direction (±Y direction) depending on the number of batteries 11 stored, etc. The container 110 may also have a function of discharging electricity to the outside. [Industrial Applicability]

[0078] The present disclosure is widely applicable to battery exchange systems and battery exchange devices that replace batteries mounted on vehicles without manual intervention. [Explanation of symbols]
