Description

[Technical Field]

[0001] The present invention relates to a vehicle charging system that charges an on-board battery using a charging device provided outside the vehicle, and to a vehicle equipped with such an on-board battery. [Background technology]

[0002] Among vehicles such as automobiles, there are electric vehicles that run by driving a drive motor with power stored in an on-board battery. Charging of the on-board battery is essential for such electric vehicles, and as a means for charging, vehicle charging systems that charge the on-board battery using a charging device installed outside the vehicle are known (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-109807 [Patent Document 2] Japanese Patent Publication No. 2022-26379 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the vehicle charging system described in Patent Document 1 requires the user (driver) to perform an operation to start charging after parking the vehicle in a specified location, and if the user forgets to perform the operation to start charging, the vehicle battery will not charge, which could result in the vehicle battery running out of power.Patent Document 2 also describes a vehicle charging system that uses a sensor to detect the vehicle's position and start charging, but this requires a mechanism for detecting the vehicle's position and operating the charging mechanism in addition to a mechanism for charging, which could complicate the configuration of the vehicle charging system.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to prevent forgetting to charge an in-vehicle battery with a simple configuration. [Means for solving the problem]

[0006] The vehicle charging system of the present invention is a vehicle charging system that charges an onboard battery installed in the vehicle using a charging device placed in the vehicle's parking space, wherein the vehicle comprises a link lever rotatably supported on the vehicle body, and a power receiving unit that moves between a stored position stored in the vehicle body and a protruding position in which a portion of the power receiving unit protrudes from the vehicle body in accordance with the rotational movement of the link lever, and the charging device comprises a road surface side link having an operating portion that comes into contact with the link lever, and a power supply unit that supplies power to the power receiving unit that has been moved to the protruding position, and the link lever is rotated while in contact with the operating portion.

[0007] This moves the power receiving unit from the housed position to the protruding position, and power is supplied from the power supply unit to the power receiving unit.

[0008] In addition, the vehicle of the present invention is a vehicle in which an onboard battery is charged by a charging device that is placed in the vehicle's parking space and has a road surface side link and a power supply unit, and is equipped with a vehicle side link that rotates while in contact with the road surface side link, and a power receiving unit that moves between a stored position stored in the vehicle body and a protruding position protruding from the vehicle body in accordance with the rotational movement of the vehicle side link.

[0009] This moves the power receiving unit from the housed position to the protruding position, and power is supplied from the power supply unit to the power receiving unit. [Effects of the Invention]

[0010] According to the present invention, the power receiving unit is moved from the stored position to the protruding position and power is supplied from the power supply unit to the power receiving unit, so charging of the vehicle battery starts automatically without the user having to perform any operation to start charging, and the simple configuration prevents the user from forgetting to charge.

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a vehicle charging system and a vehicle according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0013] In the following description, the forward direction of the vehicle is defined as the front, and the directions of front, rear, up, down, left and right are indicated. However, the directions of front, rear, up, down, left and right indicated below are for the convenience of explanation, and the present invention is not limited to these directions in its implementation.

[0014] The vehicle charging system 1 includes a vehicle 100 and a charging device 200 that is installed, for example, buried in a parking space 300 for the vehicle 100 (see FIG. 1).

[0015] <Vehicle configuration> First, the configuration of the vehicle 100 will be described (see FIGS. 1 to 4).

[0016] Vehicle 100 is, for example, an electric vehicle that runs solely on electrical power, and includes a drive motor 110, an on-board battery 120, and a vehicle-side link 130 (see FIG. 1). However, vehicle 100 may also be a hybrid vehicle that runs on at least one of fuel (gasoline) and electrical power.

[0017] The drive motor 110 is used as a power source for the vehicle 100. If the vehicle 100 is a hybrid vehicle, two drive modes are set: a hybrid drive mode using both the drive motor 110 and the engine as power sources, and a motor drive mode using only the drive motor 110 as power sources, and the two drive modes can be switched depending on the driving conditions, etc.

[0018] The in-vehicle battery 120 has a battery module (not shown) that stores power used in the vehicle 100, for example, power used by the drive motor 110, as well as power used by various parts of the vehicle 100 that are operated by the power and various lights provided on the vehicle 100. The in-vehicle battery 120 is charged with power from the charging device 200 via the power receiving unit 132. Note that the in-vehicle battery 120 may be configured to store, for example, regenerated power supplied from the drive motor 110, in addition to power obtained by external charging.

[0019] The vehicle-side link 130 is disposed on the underside of the vehicle body 101, and has a link lever 131 and a power receiving unit 132 (see FIGS. 1 to 4). A placement recess 102 and a guide hole 103, each of which opens downward, are formed on the underside of the vehicle body 101, and the link lever 131 of the vehicle-side link 130 is positioned in the placement recess 102 except for a portion, and the power receiving unit 132 is positioned in the placement recess 102 and the guide hole 103 (see FIG. 3). The vehicle body 101 is provided with a lid 104, which covers the guide hole 103 in an openable and closable manner (see FIGS. 2 to 4). The lid 104 is biased in a direction that closes the guide hole 103, for example, by a biasing member (not shown), such as a spring.

[0020] The link lever 131 has a link portion 133 whose longitudinal direction is the front-to-rear direction, a support shaft portion 134 connected to the rear end of the link portion 133, and an acted upon portion 135 connected to the front end of the link portion 133. A connecting hole 136 penetrating from left to right is formed in the link portion 133. The axial direction of the support shaft portion 134 is in the left-to-right direction, and the link lever 131 is supported by the vehicle body 101 in a state in which it can rotate around the support shaft portion 134 as a fulcrum. The acted upon portion 135 protrudes downward from the front end of the link portion 133 in a state inclined relative to the link portion 133, and its tip portion (lower end portion) is positioned below the underside of the vehicle body 101.

[0021] A holding mechanism (not shown) is provided on the underside of the vehicle body 101, and the link lever 131 is rotated between a holding position in which the link portion 133 is held in an approximately horizontal state by the holding mechanism, and a non-holding position in which the lock is released.

[0022] The power receiving unit 132 has a main body 137 and a connecting shaft 138. The main body 137 is formed, for example, in a cylindrical shape with its axial direction extending vertically. Required components, such as a connection terminal (not shown), are disposed or supported inside the main body 137. The bottom surface of the power receiving unit 132 forms a power receiving surface 132a. The power receiving unit 132 is connected to the vehicle battery 120, for example, via a connecting member (not shown) attached to the upper end of the main body 137. A magnet (not shown) is attached to the main body 137. The connecting shaft 138 has its axial direction extending horizontally, and one end is connected to the outer periphery of the main body 137 and is inserted into the connecting hole 136 of the link lever 131. A retaining member (not shown) is attached to the other end of the connecting shaft 138 to prevent the connecting member 142 from falling off the link lever 131.

[0023] As the link lever 131 rotates, the power receiving unit 132 moves up and down between a stored position where the entire main body 137 is stored inside the vehicle body 101 and a protruding position where the bottom end of the main body 137 protrudes from the vehicle body 101 (see FIGS. 2 and 4). The power receiving unit 132 is positioned in the stored position when the link lever 131 is in the held position, and is moved from the stored position to the protruding position by rotating the link lever 131 from the held position to the non-held position. The larger the rotation angle of the link lever 131 from the held position, the more the power receiving unit 132 protrudes from the vehicle body 101 at the protruding position.

[0024] <Charging device configuration> Next, the configuration of the charging device 200 will be described.

[0025] The charging device 200 has a placement base 201, a switch 202, a first road surface side link 203, a second road surface side link 204, and a power supply unit 205 (see FIGS. 5 to 11).

[0026] The placement base 201 is formed, for example, in a box shape, and is buried, for example, in the ground surface of the parking space 300 (see FIGS. 5 and 6). The placement base 201 is formed with an operation groove 206, two placement grooves 207, and a placement hole 208, each of which is open upward (toward the ground). The operation groove 206 is located at one end in the left-right direction of the parking space 300. The placement groove 207 is located inside the parking space 300 in the left-right direction from the switch 202, and is arranged side by side in a spaced-apart state in the front-to-back direction. A restricting portion 209 is provided at the outer end of the placement groove 207 in the front-to-back direction. The placement hole 208 is located on the opposite side of the switch 202 with the placement groove 207 in between in the left-to-right direction, and is located between the two placement grooves 207 in the front-to-back direction.

[0027] An inwardly projecting flange 210 is formed at the upper end of the placement hole 208, and the underside of the flange 210 is formed as a contact surface 210a (see FIG. 7). A power supply terminal 211 is disposed on the flange 210. One end of the power supply terminal 211 is exposed from the contact surface 210a. The other end (not shown) of the power supply terminal 211 is connected to a power source via a connecting wire or the like.

[0028] The placement hole 208 is covered by a cover portion 212 provided on the upper surface of the placement base 201 in an openable and closable manner. The cover portion 212 is biased in a direction that closes the placement hole 208 by a biasing member (not shown), such as a spring. However, the placement hole 208 may be configured to be opened and closed by the cover portion 212 sliding in the horizontal direction. The placement hole 208 may be covered by multiple cover portions 212.

[0029] The switch 202 is formed, for example, in a rectangular shape with the longitudinal direction being the front-to-rear direction, and is inserted into the operation groove 206 in a state in which it can move up and down (see FIGS. 5 and 6). The switch 202 is biased upward by a biasing member (not shown), and its upper end is in a state in which it protrudes from the ground. The upper surface of the switch 202 is formed as a pressing surface 202a. Depression parts 202b are provided at the front and rear end ends of the switch 202 in the ground, respectively.

[0030] The first road surface side link 203 and the second road surface side link 204 are respectively arranged in the two arrangement grooves 207, in a state where they are symmetrical in the front-rear direction.

[0031] The first road surface side link 203 is arranged in the arrangement groove 207 located on the front side, and has a first link portion 213A whose longitudinal direction is in the front-to-back direction, a pivot shaft portion 214 connected to the front end of the first link portion 213A, an action portion 215 connected to the rear end of the first link portion 213A, a second link portion 216 connected to approximately the center of the first link portion 213A in the front-to-back direction, and a wire member 217 whose one end is connected to the second link member.

[0032] The pivot shaft 214 has an axial direction extending left and right, and the first road surface side link 203 is supported in the arrangement groove 207 in a state where it can rotate around the pivot shaft 214 as a fulcrum. The action part 215 is, for example, cylindrical in shape with an axial direction extending left and right. The front end of the second link part 216 is provided as a joint part 218, and is connected to the first link part 213A in a state where it can rotate around the joint part 218 as a fulcrum. A regulated part 219 is provided at the rear end of the second link part 216. One end of a wire member 217 is connected to the regulated part 219. The other end of the wire member 217 is fixed to a fixing part 201a provided on the arrangement base 201. A part of the wire member 217 connected to the other end is formed as a pressed part 217a, and is positioned below the pressed part 202b of the switch 202.

[0033] The second road surface side link 204 is arranged in the arrangement groove 207 located on the rear side, and has a first link portion 213B whose longitudinal direction is in the front-to-rear direction, a rotating shaft portion 214 connected to the rear end of the first link portion 213B, an acting portion 215 connected to the front end of the first link portion 213B, a second link portion 216 connected to approximately the center in the front-to-rear direction of the first link portion 213, and a wire member 217 whose one end is connected to the second link member. The length in the longitudinal direction of the first link portion 213B is, for example, slightly shorter than the length in the longitudinal direction of the first link portion 213A.

[0034] The pivot shaft 214 has an axial direction extending left and right, and the second road surface side link 204 is supported in the arrangement groove 207 in a state in which it can rotate around the pivot shaft 214 as a fulcrum. The action part 215 is, for example, cylindrical in shape and has an axial direction extending left and right. The rear end of the second link part 216 is provided as a joint part 218, and is connected to the first link part 213B in a state in which it can rotate around the joint part 218 as a fulcrum. A regulated part 219 is provided at the front end of the second link part 216. One end of a wire member 217 is connected to the regulated part 219. The other end of the wire member 217 is fixed to a fixing part 201a provided on the arrangement base 201. A part of the wire member 217 connected to the other end is formed as a pressed part 217a, and is positioned below the pressed part 202b of the switch 202.

[0035] In addition, since the first link portion 213A in the first road surface side link 203 and the first link portion 213B in the second road surface side link 204 operate symmetrically in the front-to-rear direction, in the following explanation, both may be collectively referred to as the first link portion 213.

[0036] The first link portion 213 of the first road surface side link 203 and the second road surface side link 204 is rotatable between a lying position in which the acting portion 215 is positioned below the ground surface and an upright position in which the acting portion 215 is positioned above the ground surface (see Figures 5 and 8).

[0037] In charging device 200, when pressing surface 202a is pressed and switch 202 is moved downward, pressed portion 217a of wire member 217 is pressed downward by pressing portion 202b of switch 202. As pressed portion 217a is pressed down, regulated portion 219 is pulled outward by wire member 217, and second link portion 216 is moved outward. As second link portion 216 moves, first link portion 213 is rotated from the laid-down position to the upright position in accordance with the movement of second link portion 216. Regulated portion 219 comes into contact with restricting portion 209, and outward movement of second link portion 216 is restricted. As restricting portion 209 restricts movement of second link portion 216, rotation of first link portion 213 from the laid-down position by more than a predetermined rotation angle is restricted.

[0038] Conversely, when the pressure on switch 202 is released, switch 202 is moved upward by the biasing force of the biasing member. As switch 202 moves upward, wire member 217, which has been pressed down by depressing portion 202b, is relaxed, and the tension of wire member 217 on regulated portion 219 decreases. First link portion 213 is rotated from the upright position to the laid position by its own weight.

[0039] The power supply unit 205 has a cylindrical case 220 with its axis oriented vertically and two terminals 221 fixed inside the case 220, and is inserted into the placement hole 208 in a vertically movable state (see FIG. 7). For example, one of the two terminals 221 is provided as a positive electrode and the other as a negative electrode. The case 220 is formed of, for example, a magnetic material. The case 220 has a small diameter portion 222 and a large diameter portion 223. The large diameter portion 223 is continuous with the lower end of the small diameter portion 222, and the upper surface of the large diameter portion 223 forms a contact surface 223a. The upper end surface of the power supply unit 205 forms a power supply surface 205a, from which one ends of the two terminals 221 are exposed. The other ends of the terminals 221 are exposed from the contact surface 223a.

[0040] Power supply part 205 is movable up and down between a power supply position where contact surface 223a is in contact with contacted surface 210a of flange part 210 and terminal part 221 is electrically connected to power supply terminal 211, and a power supply position where terminal part 221 is disconnected from power supply terminal 211. When power supply part 205 is moved to the power supply position, the upper end of small diameter part 222 protrudes from arrangement hole 208 (see FIGS. 7 and 9).

[0041] In addition, in charging device 200, terminal portion 221 of power supply portion 205 may be exposed from the outer peripheral surface of large diameter portion 223, and power supply terminal 211 may be exposed from the inner peripheral surface of placement hole 208 (see Figure 10).

[0042] <Charging flow in a vehicle charging system> Next, the flow of charging in the vehicle charging system 1 will be described (see FIGS. 2, 5, and 11 to 20).

[0043] First, we will explain the state of each part before vehicle 100 enters parking space 300. In vehicle 100, link lever 131 is held in the held position, and power receiving unit 132 is positioned in the stored position (see FIG. 2). In charging device 200, first link portion 213 of first road surface side link 203 and second road surface side link 204 is positioned in the collapsed position, and power supply unit 205 is positioned in the power supply disabled position (see FIG. 5).

[0044] When the vehicle 100 enters the parking space 300 from this state, the wheels (front wheels) press the pressing surface 202a of the switch 202, causing the switch 202 to move downward. When the switch 202 moves downward, the pressing part 202b presses down the pressed part 217a of the wire member 217, causing the second link parts 216 to move outward in the front-to-rear direction, and the first link part 213 to rotate from the laid position to the raised position (see FIG. 11). At this time, the vehicle-side link 130 is not yet in contact with either the first road-side link 203 or the second road-side link 204, and the link lever 131 remains held in the held position.

[0045] When the vehicle 100 moves forward with the first link portion 213 rotated to the upright position, the acted-on portion 135 of the vehicle-side link 130 comes into contact with the acting portion 215 of the first road surface-side link 203 (see FIG. 12). At this time, the rotation of the first link portion 213 is restricted by the restricting portion 209. Therefore, when the vehicle 100 moves further forward with the acted-on portion 135 in contact with the acting portion 215, the acted-on portion 135 slides on the acting portion 215 of the first road surface-side link 203, causing the link lever 131 to rotate from the holding position to the non-holding position, and the power receiving portion 132 pushes open the lid portion 104 from the stored position to the protruding position (see FIG. 13). The link lever 131 rotated from the holding position to the non-holding position is further rotated by its own weight, and the amount of protrusion of the power receiving portion 132 from the vehicle body 101 gradually increases.

[0046] When power receiving unit 132 is moved to the protruding position, power feeding unit 205 is attracted and moved upward by the magnetic force of a magnet provided in power receiving unit 132. When power feeding unit 205 is moved to the power feeding position, power feeding unit 205 and power receiving unit 132 come into contact with each other, electrically connecting the two and forming a charging path to vehicle battery 120, thereby charging vehicle battery 120 (see FIG. 14).

[0047] On the other hand, when vehicle 100 moves backward while in-vehicle battery 120 is charged, the connection between power feeding unit 205 and power receiving unit 132 is released, and charging ends (see FIG. 15). When power feeding unit 205 and power receiving unit 132 are separated and the distance between them increases, the magnetic force acting on power feeding unit 205 from power receiving unit 132 weakens, and power feeding unit 205 descends under its own weight, moving from the position where power can be fed to the position where power cannot be fed.

[0048] Furthermore, when the vehicle 100 moves backward, the acted-on portion 135 of the vehicle-side link 130 slides on the acting portion 215 of the second road surface-side link 204, causing the link lever 131 to rotate from the non-retaining position toward the retaining position (see FIG. 16), and the link lever 131 rotates to the retaining position, causing the power receiving portion 132 to move to the stowed position (see FIG. 17). At this time, because the length of the first link portion 213B is shorter than the length of the first link portion 213A, the second road surface-side link 204 does not hinder the backward movement of the vehicle 100. When the vehicle 100 moves backward and the wheels move away from the switch 202, the switch 202 rises, and the first link portion 213 rotates from the upright position to the laid-down position.

[0049] Although the above example shows that the first link portion 213A and the first link portion 213B have different lengths in the longitudinal direction, the first link portion 213A and the first link portion 213B may have the same length in the longitudinal direction (see FIG. 18). In this case, for example, the first link portion 213A and the first link portion 213B are positioned so that they do not overlap in the front-to-rear direction, and a notch 135a is formed in the acted-on portion 135 of the link lever 131 (see FIGS. 18 to 20). As a result, the acting portion 215 of the second road-side link 204 passes through the notch 135a, so that the second road-side link 204 does not hinder the vehicle 100 from moving backward.

[0050] Thus, in the vehicle charging system 1, the vehicle 100 comprises a link lever 131 and a power receiving unit 132 that is moved between a stored position and an extended position in accordance with the rotational movement of the link lever 131, and the charging device 200 comprises a first road surface side link 203 and a second road surface side link 204 having an action part 215, and a power supply part 205 that supplies power to the power receiving unit 132 that has been moved to the extended position, and the link lever 131 is rotated while in contact with the action part 215.

[0051] As a result, power receiving unit 132 moves from the stored position to the protruding position, and power is supplied from power supply unit 205 to power receiving unit 132. Therefore, by parking vehicle 100 in parking space 300, charging of in-vehicle battery 120 starts automatically without the user having to perform any operation to start charging, making it possible to prevent forgetting to charge with a simple configuration.

[0052] In addition, a first road surface side link 203 and a second road surface side link 204 are provided, and the link lever 131 is rotated from the holding position to the non-holding position while in contact with the acting portion 215 of the first road surface side link 203, and is rotated from the non-holding position to the holding position while in contact with the acting portion 215 of the second road surface side link 204.

[0053] This causes the link lever 131 to rotate in the opposite direction depending on the road surface side link that is contacted, so that charging of the vehicle battery 120 can be started or stopped depending on the position of the link lever 131 relative to the road surface side link.

[0054] Furthermore, the power supply unit 205 is movable between a power-disabled position where it is located underground and a power-supplyable position where its upper end protrudes above ground.

[0055] Therefore, the amount of protrusion of the power receiving portion 132 from the vehicle body 101 at the protruding position can be reduced, and the vehicle-side link 130 can be made smaller.

[0056] Although the above example shows a case where a charging path to in-vehicle battery 120 is formed by contact between power receiving unit 132 and power feeding unit 205, a configuration may also be used in which a charging path to in-vehicle battery 120 is formed when power receiving unit 132 and power feeding unit 205 are in close proximity (non-contact). Even in this case, by moving power feeding unit 205 to a position where power can be fed, the distance between power receiving unit 132 and power feeding unit 205 is reduced, a good charging state is ensured, and the charging time can be shortened.

[0057] Furthermore, power supply unit 205 is moved up and down by the magnetic force of a magnet provided in power receiving unit 132. Therefore, no dedicated power source is required for moving power supply unit 205, and the configuration of vehicle charging system 1 can be simplified and the number of parts can be reduced.

[0058] Although the above example shows one power receiving unit and one power supply unit, two power receiving units and two power supply units may be provided. By providing two power receiving units and two power supply units, it becomes possible to arrange the positive and negative electrodes (terminal units) on the two power supply units, respectively.

[0059] Although the above example shows that the shape of power receiving surface 132a is substantially the same as the shape of power feeding surface 205a, the shape of the power receiving surface is not limited to this and may be, for example, a rectangular shape extending in the front-to-rear direction. By making the area of ​​the power receiving surface larger than the area of ​​the power feeding surface, it becomes easier to align the power receiving surface and the power feeding surface, and a good charging state can be easily ensured.
