[0042] Hereinafter, one embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0043] <1. Overall structure of the battery replacement system>

[0044] Figure 1 1 is a schematic perspective view for explaining the overall structure of the battery replacement system of the embodiment. The battery replacement system 100 replaces the battery 11 of the vehicle 10. The vehicle 10 is a large vehicle such as a truck or a bus. The vehicle 10 is parked in front of the battery replacement system 100.

[0045] In the following description, the direction from the battery replacement system 100 to the vehicle 10 is the X direction, the rearward direction in the front-to-rear direction of the vehicle is the Y direction, and the up-down direction is the Z direction. In addition, in the following description, the battery replacement system 100 is configured only on one side of the vehicle 10, but the battery replacement system 100 can also be configured on both sides of the vehicle 10 to replace the battery 11 from both sides.

[0046] The battery replacement system 100 includes: a container 110 that can be transported by a trailer, a storage unit 120 that stores the battery 11, a control unit 130, and a battery replacement device 200. The storage unit 120, the control unit 130, and the battery replacement device 200 are arranged in the container 110. In addition, the control unit 130 is not limited to being arranged in the container 130, and can also be arranged outside the container 130.

[0047] The storage section 120 is a rack capable of storing a plurality of batteries 11 in the Y direction and the Z direction. A charging device (not shown) is provided on the storage section 120. The batteries 11 stored in the storage section 120 are charged by the charging device.

[0048] The battery replacement device 200 removes the battery 11 mounted on the vehicle 10 from the vehicle 10 and accommodates it in the accommodation section 120 , and removes the charged battery 11 accommodated in the accommodation section 120 from the accommodation section 120 and mounts it on the vehicle 10 .

[0049] The control unit 130 controls the battery-replacing apparatus 200 and the charging device.

[0050] When the battery replacement device 200 is used, the container 110 is unloaded from the cargo bed of the trailer to the ground using a crane or the like, and the door of the container 110 facing the vehicle 10 is opened.

[0051] <2. Structure of battery replacement device>

[0052] Figure 2 It is a perspective view showing the overall structure of the battery replacement device 200 .

[0053] The battery exchange device 200 includes a travel frame 210, a travel rail 211, a first lift frame 220, and a revolving frame 230. The travel frame 210 moves in the ±Y direction along the travel rail 211 by the driving force of the travel actuator 212.

[0054] The first lifting frame 220 is disposed in the inner space covered by the traveling frame 210 , and moves in the ±Z directions along the lifting rails 221 by the driving force of the first lifting actuator 222 .

[0055] The rotating frame 230 is disposed in the inner space covered by the first lifting frame 220, and is rotated by means of a rotating actuator 232 ( Figure 4 )'s driving force, and rotates (rotates) with the Z direction as the rotation axis.

[0056] When mounted on the vehicle 10, the battery 11 is held by the battery holder 20. The battery holder 20 is fixed to the vehicle 10 and has the function of positioning and holding the battery 10 at a predetermined battery mounting position and guiding the battery 10 to a pull-out position described later.

[0057] Figure 3 It is a perspective view showing the detailed structure of a mechanism provided in the internal space of the revolving frame 230 . Figure 4 It is a perspective view showing the position of each actuator.

[0058] The first sliding frame 240, the second lifting frame 250 and the battery holding arm 260 are arranged in the inner space of the rotating frame 230. In addition, the battery holding arm 260 can also be called a second sliding frame.

[0059] The first slide frame 240 is slidably supported by a slide rail 241 fixed to the revolving frame 230 , and moves in the ±X directions by the driving force of the first slide actuator 242 .

[0060] The second lifting frame 250 is supported by a guide rail 251 fixed to the first slide frame 240 in a freely elevating manner, and moves in the ±Z directions by the driving force of the second lifting actuator 252 .

[0061] The battery holding arm 260 is slidably supported by a slide rail 261 fixed to the second lifting frame 250 , and moves in the ±X directions by the driving force of the battery holding arm actuator 262 .

[0062] The battery holding arm 260 has a placing portion 260a for placing the battery 11 and a pushing portion 260b for pushing the battery 11 toward the vehicle 10. The placing surface of the placing portion 260a of the battery holding arm 260 is orthogonal to the pushing surface of the pushing portion 260b, and the general shape when viewed from the ±Y direction is generally L-shaped.

[0063] The push-out portion 260b is provided with a battery position detection camera 271 and a battery detection limit switch 272. The image obtained by the battery position detection camera 271 is sent to the control unit 130, and the control unit 130 controls the positions of the components that move the battery holding arm 260 in the Y and Z directions based on the image. As a result, the battery holding arm 260 can accurately approach the position where the battery 11 is mounted, and the position in the X direction is controlled by the battery detection limit switch 272. In addition, the control unit 130 mounts the replacement battery 11 on the vehicle 10 based on the position information of the battery 11 when it is removed from the vehicle 10.

[0064] The battery detection limit switch 271 has a rod that is pressed by the side of the battery 11 when the battery 11 is placed at a predetermined position of the battery holding arm 260. The battery detection limit switch 271 detects whether the battery 11 is placed at the predetermined position of the battery holding arm 260 based on the state of the rod, and sends the detection result to the control unit 130. The control unit 130 switches the operation of each component that moves the battery holding arm 260 based on the detection result.

[0065] <3. Operation of the battery replacement device>

[0066] Next, the operation of the battery replacement device 200 will be described.

[0067] First, if Figure 5 As shown, the battery replacement device 200 moves the travel frame 210 in the Y direction so that the battery holding arm 260 is located in front of the battery 11.

[0068] The battery replacement device 200 lowers the first lifting frame 220 to the lowest position. The first lifting frame 220 may not necessarily be at the lowest position, but may be moved to a position in the vertical direction corresponding to the position of the battery 11.

[0069] Next, the battery replacement device 200 moves the first slide frame 240 toward the battery 11 (+X direction). The 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 .

[0070] Then, if Figure 6 As shown, the battery replacement device 200 lowers the second lifting frame 250. The second lifting frame 250 is lowered at least until the portion of the battery holding arm 260 holding the battery 11 reaches a position below the lower surface of the battery 11.

[0071] Then, if Figure 7 As shown, the battery replacement device 200 moves the battery holding arm 260 in the direction of the battery 11 (+X direction).

[0072] Then, if Figure 8 As shown in FIG. 1 , the battery replacement device 200 moves the battery holding arm 260 in the -X direction while the battery 11 is held by the battery holding arm 260. Figure 8 Before the state shown, first Figure 7 Starting from the state shown in the figure, the second lifting frame 250 is slightly raised. The raised position at this time is a position where the locking claw 263 formed on the battery holding arm 260 is locked with the battery 11 and the battery 11 is not lifted by the battery holding arm 260. By moving the battery holding arm 260 in the -X direction in the state where the locking claw 263 is locked with the battery 11, the battery holding arm 260 becomes Figure 8 Status shown.

[0073] Figure 8 The state shown is a state where the battery 11 is pulled out to the side of the vehicle 10. That is, Figure 8 This is a state where there is no vehicle body on the upper part of the battery 11 .

[0074] In addition, 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 restrict the position of the battery 11 in the X direction and the Y direction, and are composed 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 direction and the Y direction.

[0075] Then, if Fig. 9 As shown, the battery replacement device 200 raises the second lifting frame 250 . As a result, the battery 11 is separated from the mounting table 22 of the battery holder 20 .

[0076] The battery holder 20 includes a mounting table 22 and a slide rail 21 that supports the mounting table 22 so that the mounting table 22 can slide freely in the ±X direction. In addition, a positioning pin 23 is provided on the mounting table 22. A hole (not shown) for the positioning pin 23 to fit is formed on the lower surface of the battery 11, whereby when the battery 11 is placed on the mounting table 22, the battery 11 is positioned with high precision, and damage to the terminal caused by positional deviation of the battery 11 can be prevented.

[0077] Then, if Fig.10 As shown, the battery replacement device 200 moves the first sliding frame 240 in the −X direction until the battery 11 is located in the rotating frame 230 .

[0078] Then, if Fig.11 As shown, the battery replacement device 200 rotates the revolving frame 230. By rotating the revolving frame 230 by 180 degrees, the battery 11 is made to face the storage section 120. In addition, while the revolving frame 230 is rotating, the traveling frame 210 and the first lifting frame 220 are moved, thereby moving the battery 11 to a desired storage position of the storage section 120. Then, by moving the first sliding frame 240, the second lifting frame 250 and the battery holding arm 260, the battery 11 is stored in a predetermined position of the storage section 120. In addition, the action when storing the battery 11 can be appropriately changed according to the structure of the storage section 120, and is not particularly limited in the present disclosure.

[0079] The above has described the operation when the battery 11 is removed from the vehicle 10. When the battery 11 is mounted on the vehicle 10, an operation substantially opposite to the operation when the battery 11 is removed may be performed.

[0080] First, the battery replacement device 200 takes out the charged battery 11 from the storage unit 120. Then, the battery replacement device 200 rotates the rotating frame 230 and moves the traveling frame 210 and the first lifting frame 220. Fig.10 Status shown.

[0081] Then, the state of the battery replacement device 200 is changed from Figure 9 to Figure 8 In this way, the battery 11 is placed on the mounting table 22. At this time, the battery 11 is positioned by the positioning pin 23 and locked by the locking claw 263.

[0082] In this state, the battery holding arm 260 moves in the +X direction, so that the battery 11 is pushed out by the pushing portion 260b of the battery holding arm 260, and the position of the battery 11 is changed from Figure 8 to Figure 7 Migrate in that way. Figure 7 In this state, the battery 11 is electrically connected to the vehicle.

[0083] <4. Conclusion>

[0084] As described above, the battery replacement system and the battery replacement device of the present disclosure have the following structures.

[0085] (1) One embodiment of the battery replacement system disclosed herein is a battery replacement system 100 for replacing a battery 11 mounted on a vehicle 10, wherein the vehicle 10 includes a bracket 20 for holding the battery 11, and a battery replacement device 200 includes: an arm (battery holding arm 260) for holding the battery 11; and an arm moving unit for moving the arm (battery holding arm 260), the arm moving unit including: a first lifting unit (first lifting frame 220) for moving the arm (battery holding arm 260) at least in the up-down direction inside the device body of the battery replacement device 200; and a second lifting unit (second lifting frame 250) for moving the arm (battery holding arm 260) in the up-down direction outside the device body.

[0086] In this way, by having the first lifting part (first lifting frame 220) and the second lifting part (second lifting frame 250) share the lifting action of the arm (battery holding arm 260), a battery replacement system 100 that can quickly and highly reliably remove and install the battery 11 can be realized.

[0087] That is, the first lifting unit (first lifting frame 220) can approach the storage unit 120, and the second lifting unit (second lifting frame 250) can approach the battery 11 mounted on the vehicle 10. Therefore, even if the position of the vehicle 10 does not need to be higher than the position of the battery replacement device 200, the battery 11 mounted on the vehicle 10 can be lifted from below by the second lifting unit (second lifting frame 250) to be removed and moved. As a result, compared with the case where the battery 11 is gripped from above and moved, for example, the occurrence of the battery 11 falling off can be suppressed, and the reliability can be improved and the battery can be moved quickly.

[0088] Fig.12 1 is a side view showing the vertical positional relationship between the battery 11 mounted on the vehicle 10 and the battery replacement device 200. Fig.12 As shown, in the battery replacement device 200 of the present embodiment, even when the bottom surface of the battery 11 is located below the installation position of the battery replacement device 200, the arm (battery holding arm 260) can be lowered to a position below the bottom surface of the battery 11 by the second lifting unit (second lifting frame 250). As a result, for example, even if the vehicle 10 and the battery replacement device 200 are located on the ground at the same height, the battery 11 can be lifted and removed and moved. That is, a device or a slope for lifting the vehicle 10 is not required.

[0089] Furthermore, since the lifting and lowering operation is divided into two stages, the size of the arm in the retracted state can be reduced, thereby facilitating the accommodation of the first lifting unit and the second lifting unit into the inside of the device body.

[0090] (2) In one embodiment of the battery replacement system disclosed herein, the arm and the arm moving portion include: a first sliding portion (first sliding frame 240) that enables the arm to move at least in a direction approaching and moving away from a battery 11 mounted on a vehicle 10 in an area including the interior of a device body of the battery replacement device 200; and a second sliding portion (battery retaining arm 260) that enables the arm to move in a direction approaching and moving away from a battery 11 mounted on a vehicle 10 in an area outside the device body (±X direction).

[0091] Furthermore, since the sliding action in the ±X directions is divided into two stages, the size of the arm in the retracted state can be reduced, thereby facilitating the accommodation of the first sliding portion and the second sliding portion inside the device body.

[0092] (3) In one embodiment of the battery replacement system of the present disclosure, the arm includes a placement portion 260 a for placing the battery 11 , and a push-out portion 260 b for pushing out the battery 11 in the direction of the vehicle 10 (+X direction).

[0093] (4) In one embodiment of the battery replacement system disclosed herein, when removing the battery 11 from the vehicle 10, the arm moving unit moves the arm to the bottom of the battery 11 held by the bracket 20, and places the battery 11 on the placing portion 260a by raising the arm, and pulls the battery 11 into the device body. When installing the battery 11 on the vehicle 10, the arm moving unit moves the battery 11 removed from the accommodating portion 120 accommodating the battery 11 to the outside of the device body, and moves the battery 11 to the bracket 20 by lowering the arm, and moves the battery 11 to the electrical connection position by pushing the battery 11 in the direction of the vehicle 10 (+X direction) by the pushing unit 260b.

[0094] (5) In one embodiment of the battery replacement system disclosed herein, the bracket 20 includes: a bracket loading portion 22 for loading the battery 11; and a support portion (slide rail 21) for supporting the bracket loading portion 22 in a manner that enables the bracket loading portion 22 to slide between an electrical connection position of the battery 11 in the vehicle 10 and a battery pull-out position on the side of the vehicle 10.

[0095] Thus, when a new battery 11 is installed, the battery 11 can be positioned at a predetermined battery connection position with high accuracy. As a result, damage to the terminal caused by positional deviation of the battery 11 can be prevented.

[0096] (6) In one embodiment of the battery replacement system of the present disclosure, the locking portion (locking claw 263 ) that locks the battery 11 is formed on the placement portion 260 a of the arm (battery holding arm 260 ).

[0097] This can prevent the battery 11 from falling off the mounting portion 260 a or from being displaced.

[0098] (7) In one embodiment of the battery replacement system of the present disclosure, the bracket mounting portion 22 of the bracket 20 is provided with positioning pins 23 , and the positioning pins 23 position the mounted battery 11 at the electrical connection position.

[0099] Thus, the battery 11 is guided to the correct electrical connection position, and damage to the terminal due to deviation of the electrical connection position can be prevented.

[0100] (8) In one embodiment of the battery replacement system of the present disclosure, the battery replacement device 200 is installed in the container 110 that can be transported by a trailer.

[0101] Thus, even without constructing a fixed battery replacement station, the battery replacement system 100 can be constructed by simply transporting and installing the container 110. As a result, the equipment investment can be greatly reduced.

[0102] (9) In one embodiment of the battery replacement system of the present disclosure, the container 110 further includes a storage section 120 , a charging device for charging and discharging the battery 11 stored in the storage section 120 , and a control unit 130 for controlling the battery replacement device 200 and the charging device.

[0103] (10) A battery replacement device in one embodiment of the present invention comprises: an arm (battery holding arm 260) for holding a battery 11; and an arm moving unit for moving the arm (battery holding arm 260), the arm moving unit comprising: a first lifting unit (first lifting frame 220) for moving the arm (battery holding arm 260) at least in an up-and-down direction inside a device body of the battery replacement device 200; and a second lifting unit (second lifting frame 250) for moving the arm (battery holding arm 260) in an up-and-down direction outside the device body.

[0104] (11) In one embodiment of the battery replacement device disclosed herein, the arm and the arm moving portion further include: a first sliding portion (first sliding frame 240) that enables the arm to move at least in a direction approaching and moving away from a battery 11 mounted on a vehicle 10 in an area including the interior of a device body of the battery replacement device 200; and a second sliding portion (battery retaining arm 260) that enables the arm to move in a direction approaching and moving away from a battery 11 mounted on a vehicle 10 in an area outside the device body (±X direction).

[0105] (12) In one embodiment of the battery replacement device of the present disclosure, the arm includes a placement portion 260 a for placing the battery 11 thereon, and a push-out portion 260 b for pushing out the battery 11 in the direction of the vehicle 10 (+X direction).

[0106] (13) In one embodiment of the battery replacement device of the present disclosure, a locking portion (locking claw 263 ) for locking the battery 11 is formed on the placement portion 260 a of the arm (battery holding arm 260 ).

[0107] (14) In one embodiment of the battery replacement device of the present disclosure, the battery replacement device is installed in a container 110 that can be transported by a trailer.

[0108] (15) In one embodiment of the battery replacement system disclosed herein, there are a plurality of the above-mentioned battery replacement devices 200 including a first battery replacement device 200 and a second battery replacement device 200. When replacing the battery of the same vehicle, while the arm of the first battery replacement device 200 is removing the battery 11 from the vehicle 10, the arm of the second battery replacement device 200 is removing the battery 11 from the battery storage portion 120.

[0109] This makes it possible to realize a battery replacement system that can replace the battery 11 more quickly.

[0110] The above-mentioned embodiments are merely examples of specific implementations of the present invention, and the technical scope of the present invention should not be limited by these embodiments. That is, the present invention can be implemented in various forms without departing from the gist of the present invention or its main features.

[0111] In the above-mentioned embodiment, it is described as follows Figure 1 The battery replacement device 200 is used in a state where the container 110 has been unloaded from the cargo bed of the trailer onto the ground by a crane, etc., but it can also be used as in the case of Figure 1 Corresponding parts are marked with the same reference numerals. Fig.13 As shown, the battery replacement device 200 is used in a state where the container 110 is loaded on the cargo bed 300 of the trailer. In this way, the battery replacement can be performed more easily.

[0112] In addition to the above-mentioned embodiments, a solar panel (not shown) may be provided on the container 110, and the electricity generated by the solar panel may be used to charge the battery 11 of the storage portion 120. The container 110 may also be expanded in the longitudinal direction (±Y direction) according to the number of batteries 11 to be stored. In addition, the container 110 may also have a function of discharging to the outside.
