[0025] <Overview of the Direction Correction Device> According to one embodiment, a steering correction device corrects the orientation of a stationary vehicle. For example, the vehicle's orientation is defined by yaw angle, roll angle, and pitch angle. Here, the steering correction device is installed in a battery swapping system that automatically replaces batteries mounted on the vehicle, but is not limited thereto. The steering correction device can also be installed in a system performing vehicle maintenance.

[0026] Figure 1 This is a schematic diagram showing the configuration of a battery replacement system S in which a direction correction device 1 is installed. Figure 2 This is a schematic diagram showing the steering correction device 1 raising the wheel 110 to the raised position. Figure 1 For convenience, only a part of the battery replacement system S is shown, and components such as the device for automatic battery replacement are omitted.

[0027] The battery swapping system S includes a steering correction device 1 and a fixing platform 5. The steering correction device 1 is positioned at a location corresponding to each wheel of the vehicle 100 at its stationary position. Figure 1In the diagram, only the steering correction device 1 corresponding to the right front wheel of the vehicle 100 is shown, but in reality, multiple (specifically four) steering correction devices 1 are installed.

[0028] The fixed platform 5 is a platform fixed on the travel path of the vehicle 100. The fixed platform 5 forms a path along which the wheels 110 of the vehicle 100 pass. The fixed platform 5 is located in front of and behind the steering correction device 1.

[0029] The steering correction device 1 corrects the orientation of the vehicle 100 before battery replacement. That is, the steering correction device 1 corrects the orientation of the stationary vehicle 100 to make battery replacement easier. For example, the steering correction device 1 corrects the orientation of the vehicle 100 by moving the wheels 110 of the stationary vehicle 100 in the vehicle width direction and vertical direction.

[0030] The steering correction device 1 includes a wheel receiving section 10 that supports the wheel 110. For example, for replacing the battery, such as... Figure 2 As shown, the steering correction device 1 raises the wheel receiving section 10 that supports the wheel 110. At this time, when an external force is applied to the wheel supported by the wheel receiving section 10, the wheel may move on the wheel receiving section 10.

[0031] On the other hand, the direction correction device 1 of this embodiment includes a stop 30, which restricts the movement of the wheel when the wheel receiving part 10 is raised, the details of which will be described later. Here, the stop 30 restricts the rearward movement of the wheel so that the wheel 110 is held on the wheel receiving part 10. In particular, since the stop 30 rotates as the wheel receiving part 10 moves and is in the restricted position, it is possible to prevent the wheel 110 from falling off the wheel receiving part 10 when the wheel receiving part 10 is raised.

[0032] <Detailed Configuration of the Direction Correction Device> Reference Figures 3 to 7 Describe the detailed configuration of the orientation correction device 1. Figure 3 This is a perspective view showing the direction correction device 1 when the wheel receiving section 10 is in the lowered position. Figure 4 This is a perspective view showing the direction correction device 1 when the wheel receiving section 10 is in the raised position. Figure 5 This is a schematic diagram showing the cable mechanism 50. Figure 6 This is a schematic diagram showing the state of the cable mechanism 50 when the stop part 30 is in the standby position. Figure 7 This is a diagram showing the state of the cable mechanism 50 when the stop 30 is in the restricted position. Figure 4 For ease of explanation, the stop part 30 is transparent.

[0033] As described above, the steering correction device 1 is provided at a position corresponding to each wheel 110 of the vehicle 100, but the configuration of each steering correction device 1 is the same. Therefore, the configuration of the steering correction device 1 provided at a position corresponding to the front wheel 110 (here, the right front wheel) of the vehicle 100 will be described below.

[0034] It is assumed here that vehicle 100 is a truck. When vehicle 100 is a truck, the vehicle height at the front end of vehicle 100 is often low. Therefore, in many cases, the wheel receiving part 10 for the front wheel 110 of vehicle 100 is raised. Therefore, by providing the stop part 30, the effect of preventing the wheel 110 from falling off the wheel receiving part 10 can be achieved more effectively.

[0035] like Figure 3 As shown, the steering correction device 1 includes a wheel receiving unit 10, a transmission unit 15, a lifting mechanism 20, a stop unit 30, and a cable mechanism 50.

[0036] The wheel receiver 10 supports one wheel 110 of the vehicle 100 in the stopped position. Here, the wheel receiver 10 supports the right front wheel 110 of the truck. The length of the wheel receiver 10 in the longitudinal direction is less than the diameter of the wheel 110. In this case, although the wheel receiver 10 can be made more compact, the risk of the wheel 110 detaching from the wheel receiver 10 also increases. However, by providing the stop 30, the effect of preventing the wheel 110 from detaching from the wheel receiver 10 when it is raised can be achieved more effectively. The wheel receiver 10 in... Figure 3 The lowering position shown and Figure 4 The vehicle moves up and down between the indicated elevation positions. When the wheels 110 of vehicle 100 are on the fixed platform 5 (… Figure 1 When the wheel 110 moves upward, the wheel receiving unit 10 is in the lowered position. When the direction of the wheel 110 is corrected, the wheel receiving unit 10 will move from the lowered position to the raised position.

[0037] A conveying unit 15 is disposed on the upper surface of the wheel receiving unit 10 and has the function of moving the wheel 110 supported by the wheel receiving unit 10 along the vehicle width direction. The conveying unit 15 includes a plurality of rollers 17 arranged at predetermined intervals in the vehicle width direction. The wheel 110 contacts a portion of the plurality of rollers 17. The wheel 110 can move in the vehicle width direction by the rotation of the rollers 17 in contact with the wheel 110. While the wheel 110 is in contact with the rollers 17, the wheel receiving unit 10 moves up and down between a lowered position and a raised position.

[0038] The lifting mechanism 20 moves the wheel receiving section 10 up and down. The lifting mechanism 20 raises and lowers the wheel receiving section 10, which supports the wheel 110, between a lowered position and a raised position. The lifting mechanism 20 has a motor as a power source, and uses the motor's power to move the wheel receiving section 10 up and down. Figure 3 As shown, the lifting mechanism 20 includes a lifting unit 22, a connecting member 24, and a roller unit 26.

[0039] The lifting unit 22 is integrated with the wheel receiving section 10 (in other words, the lifting unit 22 constitutes a part of the wheel receiving section 10), and lifts the wheel receiving section 10. The lifting unit 22 is positioned facing the fixed platform 5. Specifically, the lifting unit 22 is located on the side surface of the wheel receiving section 10 (the surface facing the fixed platform 5). The lifting unit 22 is provided with a plurality of pivot support units 28.

[0040] The pivot support unit 28 pivotally supports the stop portion 30. The pivot support unit 28 supports the lower surface of the stop portion 30. A plurality of pivot support units 28 are arranged at predetermined intervals along the longitudinal direction of the lifting unit 22. Therefore, the pivot support unit 28 can pivotally support the stop portion 30 relative to the lifting unit 22.

[0041] Connecting member 24 connects lifting unit 22 and roller unit 26. One longitudinal end of connecting member 24 is connected to lifting unit 22, and the other longitudinal end of connecting member 24 is connected to roller unit 26. By pivoting connecting member 24, lifting unit 22 moves up and down.

[0042] Roller unit 26 rolls on guide unit 27, which is arranged parallel to the width direction of the vehicle. For example, roller unit 26 rolls on guide unit 27 by receiving power from a motor, which drives lifting unit 22 to move up and down. Guide unit 27 is rod-shaped. When roller unit 26 rolls, connecting member 24 pivots. When roller unit 26 rolls toward the two longitudinal ends of guide unit 27 (see...), ... Figure 4 The connecting member 24 pivots in a manner that raises the lifting unit 22. Conversely, when the roller unit 26 rolls toward the longitudinal center of the guide unit 27 (see...), Figure 3 The connecting member 24 pivots in a manner that lowers the lifting unit 22.

[0043] The stop 30 restricts the movement of the wheel 110 from the wheel receiving portion 10. The stop 30 is a plate-shaped member. The stop 30 is configured such that its longitudinal direction is parallel to the vehicle width direction. When the wheel receiving portion 10 is in the raised position, the stop 30 restricts the wheel 110 from falling off the wheel receiving portion 10. Here, the stop 30 is located behind the wheel 110 in the longitudinal direction of the vehicle 100 (see...). Figure 2The lifting unit 22 prevents the wheel 110 from falling backward from the wheel receiving section 10. When the vehicle 100 is a truck, the possibility of the wheel 110 falling backward increases as the lifting unit 22 rises. Therefore, the stop 30 is provided on the rear side of the wheel receiving section 10 in the front-rear direction.

[0044] The stop 30 is configured to have a changeable position. When the wheel receiving part 10 is in the raised position, as... Figure 4 As shown, the stop 30 is in a restricted position to restrict the wheel 110 from moving from the wheel receiving portion 10. On the other hand, when the wheel receiving portion 10 is in the lowered position, as... Figure 3 As shown, the stop portion 30 is in the standby position. When the stop portion 30 is in the standby position, it does not restrict the movement of the wheel 110. It should be noted that when in the standby position, the stop portion 30 is parallel to the upper surface of the wheel receiving portion 10.

[0045] The stop portion 30 moves between a standby position and a restricted position. The stop portion 30 is pivotally supported by the wheel receiving portion 10 and pivots between the standby position and the restricted position as the wheel receiving portion 10 moves. For example, when the wheel receiving portion 10 moves from a lowered position to a raised position, the stop portion 30, located in the standby position, moves towards the restricted position. Thus, the position and orientation of the stop portion 30 change as the wheel receiving portion 10 moves.

[0046] When in the restricted position, the stop portion 30 is positioned intersecting the lifting direction (vertical direction). Specifically, the stop portion 30 in the restricted position is inclined relative to the upper surface of the wheel receiving portion 10. The angle between the stop portion 30 in the restricted position and the upper surface of the wheel receiving portion 10 is less than 90 degrees (see...). Figure 7 In this case, even if the force applied by the wheel 110 to the plate-shaped stop 30 increases, the stop 30 will not deform and can support the wheel 110 more effectively.

[0047] When in the restricted position, the stop 30 contacts the upper surface 6 of the fixed platform 5 (see...). Figure 7 This contact restricts the pivoting of the stop portion 30, thereby keeping the stop portion 30 in the restricted position. Furthermore, since the stop portion 30 is in contact with the upper surface 6 of the fixed platform 5, a reaction force acts on the stop portion 30 from the upper surface 6. Therefore, when the wheel receiving portion 10 moves from the raised position to the lowered position, the stop portion 30 receives a reaction force from the upper surface 6 of the fixed platform 5 and pivots from the restricted position to the standby position. Therefore, lowering the wheel receiving portion 10 to the lowered position facilitates the pivoting of the stop portion 30 from the restricted position to the standby position.

[0048] When the stop part 30 is in the standby position, the stop part 30 covers the gap between the wheel receiving part 10 and the fixed platform 5 (see...). Figure 6 When the stop part 30 is in the standby position, its lower surface contacts the upper surface of the wheel receiving part 10 and the upper surface of the fixed platform 5. The upper surface of the stop part 30 is located above the upper surface of the wheel receiving part 10, and its height corresponds to the thickness of the stop part 30. Therefore, the wheel 110 passes through the stop part 30 in the standby position and is positioned on the wheel receiving part 10. Without the stop part 30, when the wheel 110 passes through the gap between the fixed platform 5 and the wheel receiving part 10, it is possible that the wheel 110 will be impacted. However, by covering the gap, the stop part 30 allows the wheel 110 to move smoothly.

[0049] The cable mechanism 50 is a mechanism used to pivot the stop 30 when the wheel receiving unit 10 moves up and down. The cable mechanism 50 includes a cable 52, one end 52a of which is connected to the stop 30. When the lifting unit 22 raises the wheel receiving unit 10 to the raised position, the cable mechanism 50 pulls the stop 30 via the cable 52, causing the stop 30 to pivot from the standby position to the restricted position. Figure 3 As shown, the cable mechanism 50 is disposed on one longitudinal end of the stop portion 30. However, this disclosure is not limited thereto, and the cable mechanism 50 may also be disposed on the other longitudinal end of the stop portion 30. The cable mechanism 50 may also be disposed at the longitudinal center of the stop portion 30.

[0050] Reference Figures 5 to 7 Describe the detailed structure of the cable mechanism 50. For example... Figure 5 As shown, the cable mechanism 50 includes a cable 52, a slider 54, a retaining part 56, a guiding unit 58, a supporting unit 60, and a coupling part 62.

[0051] Here, the cable 52 is made of metal and is used to connect the stop part 30 and the fixed platform 5. Specifically, one end 52a of the cable 52 is connected to the stop part 30, and the other end 52b is connected to the fixed platform 5 (specifically, the retaining part 56). The cable 52 is arranged in a vertical direction. When the wheel receiving part 10 moves up and down, the cable 52 can move up and down along the guide unit 58.

[0052] When the wheel receiving unit 10 moves from the lowered position to the raised position, the cable 52 pulls the stop part 30. Specifically, as Figure 7 As shown, by causing the cable 52 to bend, the stop portion 30 is pulled, causing the stop portion 30 to pivot from the standby position to the restricted position. In other words, due to the tension of the cable 52, the stop portion 30 pivots from the standby position to the restricted position.

[0053] like Figure 5As shown, slider 54 is coupled to the other end 52b of cable 52. Slider 54 can move along guide unit 58. When slider 54 moves, the position of the other end 52b of cable 52 also moves. When wheel receiving part 10 is in the lowered position, the other end 52b is located at... Figure 6 The first position shown; when the wheel receiving part 10 is in the raised position, the other end 52b is located in Figure 7 The second position shown.

[0054] The retaining part 56 is coupled to the other end 52b of the cable 52 via the slider 54. While the wheel receiving part 10 is raised to the raised position, the retaining part 56 holds the other end 52b of the cable 52 in a retaining position. Specifically, the retaining part 56 holds the other end 52b in a retaining position when the wheel receiving part 10 is raised to the raised position. Even during the rising of the wheel receiving part 10 toward the raised position, the retaining part 56 holds the other end 52b in a retaining position. Furthermore, when the wheel receiving part 10 is in the raised position, the retaining part 56 holds the other end 52b in a retaining position. That is, the retaining position of the other end 52b is a second position. Therefore, one end 52a of the cable 52 pulls the stop part 30 while the other end 52b is held in the retaining position, causing the stop part 30 to pivot to a limiting position.

[0055] Here, the retaining part 56 is a spring member that pulls the other end 52b downward via the slider 54. Specifically, the spring member is a tension spring. Due to the elastic force of the tension spring, the retaining part 56 holds the other end 52b in the retaining position. One end of the spring member is connected to the support portion 54a of the slider 54, and the other end of the spring member is connected to the support portion 57a ​​of the fixing part 57. The slider 54 is pulled by the elastic force of the contracting spring member. The slider 54 rises under the action of this elastic force.

[0056] like Figure 6 As shown, a guide unit 58 is mounted on a fixed platform 5. The guide unit 58 is parallel to the vertical direction and guides the slider 54 to move vertically. The guide unit 58 includes a groove 58a extending vertically, within which the slider 54 moves. For example, when the wheel receiving part 10 moves to the raised position, the guide unit 58 guides the other end 52b to rise from the first position to the second position (holding position). Similarly, when the wheel receiving part 10 moves to the lowered position, the guide unit 58 guides the other end 52b to descend from the second position to the first position.

[0057] like Figure 6As shown, the support unit 60 is positioned above the guide unit 58 in the fixed platform 5 to contact the cable 52. Here, the support unit 60 is a shaft, and the cable 52 contacts the outer peripheral surface of the shaft. For example, when the other end 52b of the cable 52 is in the holding position, the support unit 60 contacts the bent cable 52. Therefore, the support unit 60 can keep the cable 52 taut, thereby facilitating the pulling of the stop 30 via the cable 52 and enabling the stop 30 to pivot smoothly.

[0058] The coupling part 62 rotatably couples one end 52a of the cable 52 to the stop part 30. The coupling part 62 is fixed to one end 52a. The coupling part 62 is rotatably coupled to, for example, a coupling part 32 provided on the lower surface of the stop part 30. Therefore, when the stop part 30 pivots, the coupling part 62 and one end 52a are rotatable. Thus, when the cable 52 bends with the pivoting of the stop part 30, one end 52a of the cable 52 rotates relative to the stop part 30 through the coupling part 62, thereby preventing one end 52a from twisting. Therefore, during the pivoting of the stop part 30, the cable 52 remains taut, thereby allowing one end 52a to reliably pull the stop part 30.

[0059] <Edit> Although the retaining part 56 is described as a spring member in the above description, this embodiment is not limited to this. For example, the retaining part 56 can be a weight coupled to the other end 52b located vertically below one end 52a of the cable 52. In this case, since the weight pulls the other end 52b downward, the other end 52b of the cable 52 can be held in the retaining position by a simple configuration.

[0060] Furthermore, in the above description, the stop portion 30 restricts the wheel 110 from moving backward on the wheel receiving portion 10, but this embodiment is not limited to this. For example, the stop portion 30 may be provided at a position that restricts the wheel 110 from moving forward on the wheel receiving portion 10.

[0061] Furthermore, in the above description, the steering correction device 1 provided at a position corresponding to the front wheel of the vehicle 100 includes a stop portion 30, but is not limited thereto. For example, the steering correction device 1 provided at a position corresponding to the rear wheel of the vehicle 100 may include a stop portion 30. Each steering correction device 1 provided at a position corresponding to the wheel of the vehicle 100 may include a stop portion 30.

[0062] <Effects of the Example> The direction correction device 1 in the above embodiment includes: a lifting unit 22 that lifts and supports the wheel receiving portion 10 of the wheel 110; and a stop portion 30 that is pivotally supported by the wheel receiving portion 10 between a standby position and a restricted position, for restricting the movement of the wheel 110 from the wheel receiving portion 10. Furthermore, the direction correction device 1 also includes a cable mechanism 50 with a cable 52, one end of which is connected to the stop portion 30. When the lifting unit 22 lifts the wheel receiving portion 10 to the raised position, the cable mechanism 50 pulls the stop portion 30 by the cable 52, pivoting the stop portion 30 from the standby position to the restricted position. Thus, when the wheel receiving portion 10 moves to the raised position, the cable 52 of the cable mechanism 50 pulls the stop portion 30, pivoting the stop portion 30 to the restricted position. Therefore, if the wheel 110 is subjected to an external force and tends to move when the wheel receiving portion 10 is raised, the wheel 110 will contact the stop portion 30, thereby preventing the wheel 110 from falling off the wheel receiving portion 10.

[0063] This disclosure has been described based on exemplary embodiments. The technical scope of this disclosure is not limited to the scope explained by the above embodiments, and various changes and modifications can be made within the scope of this disclosure. For example, all or part of the apparatus can be configured with any functionally or physically distributed or integrated units. Furthermore, new exemplary embodiments resulting from any combination of these are also included in the exemplary embodiments. Moreover, the effects of the new exemplary embodiments resulting from the combination also have the effects of the original exemplary embodiments.
