[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-6591 Summary of the Invention [Problem to be solved by the invention]

[0004] In the invention of Patent Document 1, if the service bay is located underground, it is necessary to construct a service bay underground, resulting in a large-scale system. Even if the service lane is a raised floor type as shown in Figure 3 of Patent Document 1, vertical space and space for a slope to move the vehicle to the raised floor position are required, resulting in a large-scale system.

[0005] The present invention has been made in view of the above, and aims to provide a technology that allows for securing space under a vehicle with a simple configuration and enabling work to be performed under the floor. [Means for solving the problem]

[0006] The vehicle cradle of the present invention comprises a first support part that supports a first wheel of a vehicle, a second support part that supports a second wheel of the vehicle spaced from the first wheel in the width direction of the vehicle, a third support part that supports a third wheel of the vehicle spaced from the first wheel in the length direction of the vehicle, a fourth support part that supports a fourth wheel of the vehicle spaced from the third wheel in the width direction of the vehicle, a first cradle having the first support part and the second support part at a predetermined height, and a second cradle spaced from the first cradle and having the third support part and the fourth support part at a predetermined height, wherein in the first cradle, the first support part or the second support part moves in the width direction of the vehicle, and in the second cradle, the third support part and the fourth support part move in the length direction of the vehicle, and the third support part or the fourth support part also moves in the width direction.

[0007] This allows for space to be secured under the vehicle, making it possible to carry out work under the floor without using a large-scale system.

[0008] In the above, the first support portion, the second support portion, the third support portion, and the fourth support portion may each include a wheel chock that stops rotation of a wheel of the vehicle.

[0009] This makes it possible to prevent the vehicle from falling off the first support portion, the second support portion, the third support portion, and the fourth support portion.

[0010] Furthermore, in the above, the first frame has a first beam stretched across the width direction, and the first support part or the second support part that moves in the width direction clamps the first beam from above and below with wheels and moves in the width direction along the first beam; the second frame has a second beam stretched across the length direction and a first movable part that moves along the second beam, and the first movable part clamps the second beam from above and below with wheels and moves in the length direction along the second beam; the first movable part has a third beam stretched across the width direction and a second movable part that moves along the third beam, and the second movable part clamps the third beam from above and below with wheels and moves in the width direction along the third beam.

[0011] This makes it possible to prevent the moving first support part or the second support part from falling off the first frame, and to prevent the moving third support part and the fourth support part from falling off the second frame.

[0012] In addition, in the above, the support parts that move in the width direction in the first support part, the second support part, the third support part, and the fourth support part may have side plates that contact the sides of the wheels they support, and may be pushed by the wheels to move in the width direction.

[0013] This allows the distance between the first support portion and the second support portion and the distance between the third support portion and the fourth support portion to be adjusted to the tread width of the vehicle. [Effects of the Invention]

[0014] The vehicle cradle according to the present invention has an effect of ensuring space under the vehicle with a simple configuration, allowing work to be performed under the floor. [Brief explanation of the drawings]

[0027] Figure 2 is a side view of an electric vehicle EV. The electric vehicle EV has a traction battery BAT under the floor, which serves as the power source for the motor that drives the wheels. In the following description, the wheelbase of the electric vehicle EV is defined as L, and the tread width is defined as W.

[0028] 3 is a front view of the vehicle cradle 1 before the electric vehicle EV is placed on it. A worker removing the drive battery BAT from the electric vehicle EV first moves the rear wheel support part 20 in the X-axis direction so that the distance between the first support part 31 and the third support part 21 and the distance between the second support part 32 and the fourth support part 22 becomes equal to L, which is the wheelbase of the electric vehicle EV. Here, because the rear wheel support part 20 can be moved in the X-axis direction by the wheels WR of the movable part 20R and the wheels WL of the movable part 20L, the worker can easily adjust the distance between the first support part 31 and the third support part 21 and the distance between the second support part 32 and the fourth support part 22.

[0029] Furthermore, the worker sets the distance between the first support portion 31 and the second support portion 32 to be shorter than the tread width W, and the distance between the third support portion 21 and the fourth support portion 22 to be shorter than the tread width W. Here, the second support portion 32 is movable in the Y-axis direction by the wheels WC of the movable portion 30, and the fourth support portion 22 is movable in the Y-axis direction by the wheels WD of the movable portion 20C, so the worker can easily adjust the distance between the first support portion 31 and the second support portion 32 and the distance between the third support portion 21 and the fourth support portion 22.

[0030] 4A and 4B are diagrams illustrating the operation of loading an electric vehicle EV onto the vehicle cradle 1. As shown in Fig. 4A, an operator OP loads the electric vehicle EV onto the forks of a forklift FT, and then presses the left side of the left front wheel against side plate 322 and the left side of the left rear wheel against side plate 222 to move the electric vehicle EV in the +Y direction. Because the left side of the left front wheel is pressed against side plate 322 and the left side of the left rear wheel is pressed against side plate 222, as shown in Fig. 4B, the second support part 32 is moved in the +Y direction by the movable part 30, and the fourth support part 22 is moved in the +Y direction by the movable part 20C.

[0031] 5A is a diagram showing the state in which an electric vehicle EV is placed on the vehicle cradle 1. When the right front wheel is positioned on the first support part 31 and the right rear wheel is positioned on the third support part 21 as shown in FIG. 4B, the worker OP lowers the forks of the forklift FT, and places the right front wheel on the first support part 31, the left front wheel on the second support part 32, the right rear wheel on the third support part 21, and the left rear wheel on the fourth support part 22. Each wheel of the electric vehicle EV placed on the vehicle cradle 1 is positioned between the wheel chocks of the respective support parts, so that forward and backward movement is restricted.

[0032] Fig. 5B is a diagram showing a state immediately before the electric vehicle EV is placed on the vehicle stand 1. As shown in Fig. 5B, even if the distance between the first support part 31 and the third support part 21 and the distance between the second support part 32 and the fourth support part 22 are longer than the wheelbase L, when the forks of the forklift FT are lowered, the right rear wheel of the electric vehicle EV comes into contact with the wheel stopper 211F and the left rear wheel comes into contact with the wheel stopper 221F, causing the movable parts 20L and 20R to move in the +X direction, so that the distance between the first support part 31 and the third support part 21 and the distance between the second support part 32 and the fourth support part 22 can be adjusted to the wheelbase L of the electric vehicle EV.

[0033] Figure 6 is a diagram illustrating the process of removing the traction battery BAT from the electric vehicle EV. The worker OP places the table lift TL, which is used to place the traction battery BAT, under the electric vehicle EV from between the first frame 3 and the second frame 2. The worker OP places the traction battery EV, which has been removed from under the floor of the electric vehicle EV, onto the table lift TL and carries the traction battery EV out from between the first frame 3 and the second frame 2.

[0034] Here, because the electric vehicle EV is supported not by its rocker panels but by its wheels, the drive battery BAT removed from under the floor does not interfere with the support of the electric vehicle EV, allowing for easy removal. Furthermore, the vehicle cradle 1 allows the position of the rear wheel support portion 20 in the X-axis direction to be adjusted to match the wheelbase L, and the spacing between the third support portion 21 and the fourth support portion 22 and the spacing between the first support portion 31 and the second support portion 32 to be adjusted to match the tread width W, making it possible to remove the drive battery B for a variety of vehicle types, from compact to large. Furthermore, the vehicle cradle 1 allows the spacing between the third support portion 21 and the fourth support portion 22 and the spacing between the first support portion 31 and the second support portion 32 to be adjusted independently, making it possible to support electric vehicles EVs with different tread widths for the front and rear wheels. Furthermore, since the vehicle cradle 1 is separated into the first cradle 3 supporting the front wheels and the second cradle 2 supporting the rear wheels, when the worker OP or the table lift TL moves under the electric vehicle EV, there is nothing obstructing their movement, allowing them to work efficiently. Furthermore, in this embodiment, each movable part is configured to sandwich the beam, preventing them from falling off the beam. Even if the vehicle to be placed on the vehicle cradle 1 is a hybrid vehicle or a plug-in hybrid vehicle, various vehicle models can be placed on the vehicle cradle 1 to remove parts from under the floor. Furthermore, if the vehicle to be placed on the vehicle cradle 1 is an engine vehicle, various vehicle models can be placed on the vehicle cradle 1 to perform work under the floor.

[0035] [Variations] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be implemented in various other forms. For example, the above-described embodiments may be modified as follows to implement the present invention. The above-described embodiments and the following modifications may be combined with each other. The present invention also includes configurations in which the components of the above-described embodiments and modifications are appropriately combined. Furthermore, further effects and modifications can be easily derived by those skilled in the art. Therefore, the broader aspects of the present invention are not limited to the above-described embodiments and modifications, and various modifications are possible.

[0036] Fig. 7 is a front view of a vehicle cradle according to a modified example of the present invention. In the present invention, the position of support leg 212F may be shifted in the -X direction from the position shown in Fig. 1B, and the position of support leg 312R may be shifted in the +X direction from the position shown in Fig. 1B. In this modified example, even if the wheelbase L is the same, the distance from support leg 212F to support leg 312R is longer, making it possible to ensure a larger space below the electric vehicle EV.

[0037] In the present invention, the fourth support part 22 may not have the side plate 222, and the second support part 32 may not have the side plate 322. In this configuration, when the electric vehicle EV is mounted on the vehicle stand 1, the distance between the first support part 31 and the second support part 32 is adjusted in advance to match the tread width W of the electric vehicle, and the distance between the third support part 21 and the fourth support part 22 is also adjusted.

[0038] 8A and 8B are schematic diagrams of a third support section 21A according to a modified example of the present invention. The beam 23Ra is an H-shaped steel member that replaces the beam 23R and spans from the support column 25R to the support column 26R along the X-axis direction. A fixing plate 217, which is a metal strip-shaped plate, is fixed along the X-axis direction to the end of the upper surface of the beam 23Ra in the -Y direction. A plurality of through holes 217a that penetrate the fixing plate 217 in the Y-axis direction are formed in the fixing plate 217 along the X-axis direction. The support leg 212 is a member that supports the bottom plate 210 and is fixed to the base 215. The base 215 is a rectangular plate-like member, and trapezoidal side plates 213 are fixed to the ends in the +Y direction and the -Y direction. A wheel support section 216 that supports the wheel WRa is fixed below the base 215. A rectangular, plate-like side plate 214 is fixed to the side plate 213. The side plate 214 supports the wheel WRb. The third support portion 21A sandwiches the beam 23Ra between the wheels WRa and Wrb in the +Z and −Y directions, and is movable in the X-axis direction. With this configuration, the beam 23R is sandwiched vertically between the wheels WRa and WRb, and the beam 23Ra is sandwiched between the side plates 214 in the Y-axis direction, preventing the third support portion 21A from falling off the beam 23Ra. The side plates 214 are formed with through-holes 214a that penetrate in the Y-axis direction. The rod-shaped portions of pin 218, which is in the form of an eyebolt, are inserted into through-holes 214a and 217a from the −Y direction. After the right rear wheel of the electric vehicle EV is placed on the third support portion 21A, the worker inserts pin 218 into both through-holes 214a and 217a from the −Y direction. When pin 218 is inserted into both through-hole 214a and through-hole 217a, even if a force in the X-axis direction acts on third support portion 21A, pin 218 is applied to fixed plate 217, preventing rear wheel support portion 20, fourth support portion 22, and third support portion 21A from moving in the X-axis direction. Note that the other fourth support portion 22 and second support portion 32 may also have the same configuration as third support portion 21A, with corresponding fixed plates 217 provided on the beams, and pin 218 may prevent movement in the Y-axis direction.

[0039] In the present invention, the fourth support part 22 may be fixed on the movable part 20L, the third support part 21 may be movable in the Y-axis direction, and the second support part 32 may be fixed on the beam 33L, and the first support part 31 may be movable in the Y-axis direction. In this modified example, the electric vehicle EV is transported by a forklift FT from the +Y-axis direction to the -Y-axis direction and placed on the vehicle stand 1.

[0040] The front wheels may be placed on the second frame 2, and the rear wheels may be placed on the first frame 3. In this case, the fourth support part 22 supports the right front wheel of the electric vehicle EV, the third support part 21 supports the left front wheel of the electric vehicle EV, the second support part 32 supports the right rear wheel of the electric vehicle EV, and the first support part 31 supports the left rear wheel of the electric vehicle EV.
