Description

Technical Field

[0001] The present invention relates to a boarding and disembarking device, and in particular to a boarding and disembarking device for a cockpit of a simulator. Background Art

[0002] In the past, as an example of a simulator, for example, a driving simulator described in Patent Document 1 changes the posture of a simulated vehicle body relative to a floor surface by a servo cylinder. By combining the change in the posture of the simulated vehicle body (cockpit) relative to the floor surface with an image projected onto a screen by a projector, it is possible to simulate a situation where a driver riding in the simulated vehicle body drives a car.

[0003] Getting on and off the cockpit in the simulator is performed via a boarding and alighting device such as a bridge that is arranged so as to avoid actuators such as servo cylinders provided on the floor surface.

[0007] Problems to be solved by the invention

[0008] However, the driving simulator is preferably capable of handling both the case where the cockpit is a right-hand steering wheel and the case where the steering wheel is a left-hand steering wheel. In this case, if the boarding and alighting port of the boarding and alighting device is set corresponding to the cockpit of the right-hand steering wheel, boarding and alighting relative to the cockpit in the case of the left-hand steering wheel becomes unfree. For example, the driver needs to move in a relatively narrow cockpit and move to the seat of the left-hand steering wheel. In this regard, it is considered to use two boarding and alighting devices, but in this case, problems such as increased costs arise.

[0009] Therefore, an object of the present invention is to provide a boarding and alighting device that can support boarding and alighting from different left and right boarding and alighting gates of a cockpit of a simulator using a single boarding and alighting device.

[0012] In addition, the above-mentioned boarding and alighting device may be such that the bridge further includes a telescopic mechanism.

[0013] In addition, the above-mentioned boarding and alighting device may also be that the boarding and alighting entrances are two left and right boarding and alighting entrances of the cockpit.

[0014] Furthermore, the above-mentioned boarding and descending device may be configured such that the moving mechanism includes a trapezoidal lead screw for left-right movement.

[0015] In addition, the above-mentioned boarding and descending device may be configured such that the moving mechanism includes a motor for left-right movement and a trapezoidal lead screw for left-right movement.

[0016] In addition, the above-mentioned boarding and alighting device may be configured so that boarding and alighting can be performed from left and right boarding and alighting openings of the cockpit by replacing the front end portion of the bridge frame and the safety gate near the front end portion.

[0017] In addition, the above-mentioned boarding and descending device may be configured such that the above-mentioned bridge includes a plurality of bridges, and the above-mentioned telescopic mechanism is a mechanism in which the plurality of bridges are stored in a nested structure and are extended and expanded relative to each other during use.

[0018] Furthermore, in the above-mentioned boarding and descending device, the above-mentioned telescopic mechanism may further include a ball screw and a linear guide.

[0019] In addition, the above-mentioned boarding and descending device may be configured such that the above-mentioned telescopic mechanism is composed of a pop-up bridge.

DETAILED DESCRIPTION

[0037] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0038] Figure 1 It is a perspective view showing the structure of a driving simulator 100 according to one embodiment of the present invention.

[0039] like Figure 1 As shown, the driving simulator 100 is configured to include: a cockpit 110; an actuator system 120 that moves the cockpit; a screen 130 that is used to reflect the scenery seen from the cockpit according to the movement of the cockpit; a corridor 140 that is a boarding and disembarking device relative to the cockpit 110; a platform 150 that is provided with a boarding and disembarking device and is used for the driver to board and disembark; and a concave pit 160 that is equipped with the actuator system 120 and has a bottom surface (floor surface) lower than the platform 150 (see Figure 3 (b)). The platform 150 has a base 180 for fixing the corridor bridge 140. The base 180 includes a left-right moving mechanism 190, which is a moving mechanism for moving the corridor bridge 140 to the left and right of the base 180. That is, in this embodiment, as the cockpit 110, two ( Figure 1Indicates the right steering wheel). At this time, the details of the left-right moving mechanism 190 will be described later, and according to the right steering wheel and the left steering wheel of the cockpit 110, the corridor 140 is moved left and right to the base 180, corresponding to the boarding and alighting entrance of the cockpit 110. In addition, the present embodiment relates to a simulator of a car as a driving simulator 100, but is not limited to this. For example, according to the following description, it can be seen that it can be used as a simulator of a moving body such as a railway vehicle or an airplane. In addition, in the present embodiment, the case where the driving simulator 100 has a pit 160 is described, but it is not limited to this. For example, the pit 160 may not be provided, and the platform may be simply lifted from the floor surface to a higher position according to the position of the cockpit.

[0040] Cockpit 110( Figure 1 Indicates the right steering wheel) is a simulated boarding part for the driver to board and drive, and has a steering wheel, seats, dashboard, rearview mirror, right door 115, left door 116 and other structures for simulating the driving of an actual car. In addition, the cockpit 110 has a plurality of boarding and alighting openings. In the present embodiment, there are a right boarding and alighting opening 110a and a left boarding and alighting opening 110b corresponding to the right door 115 and the left door 116, respectively. The corridor bridge (boarding and alighting device) 140 for the driver to board and alight relative to the cockpit 110 is provided on the platform 150, and its details will be described later. When the driver boards or alights, it is extended as a whole, and its front end portion becomes a position corresponding to the right boarding and alighting opening 110a of the cockpit 110 ( Figure 1 140 is shown in the state at this time). In addition, in this state, a pair of support legs 172 provided on the lower surface of the front end of the corridor bridge 140 extends into the pit 160 provided with the actuator system 120 and contacts the floor surface thereof. Thus, the front end of the corridor bridge 140 is supported by the support legs 172. In addition, when no simulation is performed, the corridor bridge 140 is in a state where the support legs 172 are retracted and the entirety is retracted and located on the platform 150 (refer to Figure 4A (a)). That is, when using the driving simulator 100, first, the corridor 140 is extended so that its front end portion corresponds to the position corresponding to the right boarding and alighting entrance 110a of the cockpit 110. Next, the driver opens the entrance door 142 on the platform 150, which is located near the front side of the corridor 140, and boards the corridor, and reaches the boarding and alighting opening 141a along the safety barrier 146, and boards the cockpit 110 through the opening. After using the driving simulator 100, in contrast to the above, the driver transfers from the cockpit 110 to the corridor 140 through the boarding and alighting opening 141a at the front end of the corridor 140, and moves to the platform 150 through the entrance door 142 located on the platform 150 side of the corridor 140. Then, the corridor 140 is retracted to be in the storage state.

[0041] Figure 2 (a) and Figure 2(b) is a schematic top view showing different stop positions of the cockpit when the cockpit 110 is a right-hand steering wheel and a left-hand steering wheel, and the positional relationship between the bridge 140 and the cockpit 110. The stop position of the cockpit is the position for the driver to board and alight during the simulation.

[0042] like Figure 2 As shown in (a), when the cockpit 110 is a right-side steering wheel, the cockpit 110 stops at a stop position to the right of the center line L1 when viewed from above the base 180. At this time, the corridor 140 is located on the right side of the base 180 to correspond to the stop position of the cockpit 110 with a right-side steering wheel.

[0043] like Figure 2 As shown in (b), when the cockpit 110 is a left-side steering wheel, the cockpit 110 stops at a stop position that reaches the left side of the center line L1 when viewed from above the base 180. At this time, the corridor bridge 140 is located on the left side of the base 180 to correspond to the stop position of the cockpit 110 with a left-side steering wheel.

[0044] Thus, in this embodiment, the cockpit 110 stops at different positions in the case of the right steering wheel and the case of the left steering wheel. Therefore, as described above, in order to cope with the different stop positions of the cockpit 110 by a corridor bridge 140, the base 180 has a left-right moving mechanism 190 described later.

[0045] Figure 3 (a) and Figure 3 (b) represents Figure 1 An enlarged top view and an enlarged side view are shown showing the positional relationship between the corridor 140 and the cockpit 110 corresponding to the right boarding and alighting gate 110a.

[0046] like Figure 3 As shown in (a), the corridor bridge 140 is extended from the platform 150 so that its front end reaches a position adjacent to the cockpit 110. At this time, the corridor bridge 140 extends toward the cockpit 110 stopped at a predetermined stop position without contacting the cockpit 110. In addition, the right door 115 of the cockpit 110 opens toward the side of the boarding and disembarking opening 141a at the front end of the corridor bridge 140, thereby ensuring the boarding and disembarking path of the driver from the corridor bridge 140 to the cockpit 110. In addition, since the corridor bridge 140 does not contact the cockpit 110, the weight of the corridor bridge 140 and the impact during extension and retraction will not be applied to the cockpit 110, and will not affect the cockpit 110 and the actuator system 120 described later. In addition, in the case of the corridor bridge 140 corresponding to the left steering wheel, the left door 116 of the cockpit 110 opens toward the side of the boarding and disembarking opening 141b at the front end of the corridor bridge 140.

[0047] In addition, if Figure 3 As shown in (b), the structure is such that when the corridor bridge 140 is extended, the bottom surface of the corridor bridge 140 and the bottom surface of the cockpit 110 are at the same height. In this way, even if the height of the cockpit 110 from the floor where the actuator system 120 is installed to the cockpit 110 is relatively high, by using the corridor bridge 140 of this embodiment, the corridor bridge 140 can be easily installed in the cockpit 110, and it can be removed. In addition, since the driver can get on and off the cockpit 110 on foot on the corridor bridge 140, it is possible to move in the same way as an actual vehicle that is boarded on foot on the ground, and a high sense of immersion can be obtained.

[0048] Reference Figure 1 , Figure 3 (b), the actuator system 120 has three actuators 121a, 121b, and 121c that are evenly separated and arranged at three locations along the circumferential direction in a manner surrounding the cockpit 110. Parts of these three actuators can be retracted in their respective axial directions, and are connected to a swing base 111 fixed to a cockpit support platform via a hexapod 124, and the cockpit support platform is provided on the bottom side of the cockpit 110. In addition, the hexapod 124 is fixed to a fixed platform 126. Thus, the actuator system 120 can drive the actuators 121a, 121b, and 121c through a driving source such as hydraulic pressure, so that the cockpit 110 moves in the X and Y axis directions. In addition, through the hexapod 124, the cockpit 110 can move in six degrees of freedom in the three-axis directions of X, Y, and Z and the rotation directions around each of these axes. The operation of the cockpit based on these actuators 121a, 121b, 121c and the hexapod 124 is controlled by a host computer (not shown).

[0049] The screen 130 is installed above the pit 160 so as to surround the cockpit 110, and projects images by a projector (not shown) suspended from the ceiling. In order to avoid the driving sources, hydraulic pipes, etc. of the actuators 121a, 121b, and 121c installed on the floor surface of the pit 160, the screen 130 is located at a predetermined height from the floor surface of the pit.

[0050] When receiving image signals from a computer (not shown), the projector projects images of scenery seen from inside the vehicle when driving on a simulated driving road, i.e., simulated images, onto the screen 130 based on the image signals. The driver obtains information on the driving road, signs, traffic lights, other vehicles, pedestrians, etc. while observing the simulated images projected on the screen 130, and performs driving operations according to the information.

[0051] Among them, the three actuators 121a, 121b, 121c, the hexapod 124 and other driving mechanisms are provided, and in particular, when the actuator of the hexapod 124 has a relatively high stroke, the height of the cockpit 110 provided on the upper side of the hexapod 124 becomes relatively high. Therefore, in this embodiment, the above-mentioned driving mechanism is provided in a pit that is a recessed portion relative to the platform 150. In addition, by providing the pit, it is configured so that boarding and disembarking to the cockpit 110 are performed using the corridor 140, and the corridor 140 provided on the platform is retractable relative to the cockpit 110.

[0052] The platform 150 is a scaffold for the driver to enter the room where the driving simulator 100 is installed and get on the upper part of the corridor 140. The platform 150 is made of concrete, for example, and has a horizontal floor surface at the upper part. In addition, the aforementioned pit 160 is provided in the center of the platform 150.

[0053] The covered bridge 140 is installed and fixed to the platform 150 via a base 180. The base 180 is fixed by being embedded in the platform 150 when laying concrete constituting the platform 150. In addition, the base 180 is supported on the floor surface of the pit 160 by fixing legs 181.

[0054] The base 180 includes a left-right moving mechanism 190, whereby the corridor 140 is moved so as to correspond to the right and left entrances 110a and 110b depending on whether the cockpit 110 has a right-hand steering wheel or a left-hand steering wheel, as described in detail later.

[0055] Figure 4A (a), (b) and Figure 4B (c) is a diagram illustrating the corridor 140 corresponding to the right boarding and alighting entrance 110a of the present embodiment. In addition, as will be described in detail later, the corridor 140 corresponding to the left boarding and alighting entrance 110b has a different structure of the front end and the boarding and alighting opening from the corridor 140 corresponding to the right boarding and alighting entrance 110a, and also has a different position on the base 180.

[0056] Figure 4A(a) is a three-dimensional diagram showing the storage state of the corridor bridge 140 corresponding to the right boarding and alighting entrance 110a according to an embodiment of the present invention. In the present embodiment, the corridor bridge 140 has a structure formed by connecting rectangular frames that also serve as safety barriers 146, namely a bridge 143. The bridge 143 has a plurality of bridges, which are composed of a first bridge 143a, which is a fixed portion to the platform 150, a second bridge 143b, which is a middle portion, and a third bridge 143c, which is a front end portion. In addition, the bridge has a telescopic mechanism, and when in use, the first bridge 143a, the second bridge 143b, and the third bridge 143c are extended and expanded relative to each other, and in addition, they are contracted and stored relative to each other in the opposite direction. The first bridge 143a of the corridor bridge 140 is fixed to a fixed platform, namely a base 180, which is used to fix to the platform 150. By means of the telescopic mechanism, when the corridor bridge 140 is in the storage state, the first bridge 143a, the second bridge 143b, and the third bridge 143c are nested with each other and contracted, so as to be stored as a whole on the base 180. In addition, for example, the bridge 143 may also be a truss structure. If the bridge 143 is a truss structure, the rigidity of the bridge 143 can be fully ensured during the telescopic state and in the state after the extension and expansion, and the telescopic state of the bridge 143 and the telescopic state of the supporting legs 172 described later will not be hindered. In addition, in the present embodiment, the bridge 143 is composed of a plurality of bridges, namely three bridges, but it is not limited to this, and for example, it may also be composed of two bridges, four bridges, or five or more bridges.

[0057] Figure 4A (b) is a perspective view showing a state of the corridor 140 corresponding to the right boarding and alighting entrance 110a according to an embodiment of the present invention being deployed in the middle of deployment. From the aforementioned storage state, the telescopic mechanism, i.e., the first telescopic motor 148a, which is a driving device for driving the telescopic mechanism, is used to rotate the telescopic mechanism, i.e., the first telescopic ball screw 148b, thereby the third bridge 143c is extended and deployed along the telescopic mechanism, i.e., the first telescopic linear guide 148c, relative to the first bridge 143a in the direction of the cockpit 110. In addition, at the same time, by rotating the second telescopic ball screw 149b using the second telescopic motor 149a, the second bridge 143b is extended and deployed along the second telescopic linear guide 149c relative to the first bridge 143a in the direction of the cockpit 110. In this way, since the telescopic mechanism is composed of a ball screw, the speed of telescopic expansion can be increased compared with the case of using other screws. In addition, as described above, the corridor 140 becomes a nested structure in which the first bridge 143a, the second bridge 143b, and the third bridge 143c move and telescope relative to each other. Thus, the corridor bridge 140 only extends toward the cockpit 110, and can prevent collision with the cockpit 110, the screen 130 and other peripheral equipment. In addition, due to such a nested structure, the number of parts is small and simple compared to the case where the bridge is telescopic in an accordion-type or a telescopic type, and the installation of the safety barrier is easy.

[0058] Figure 4B(c) is a perspective view showing the embodiment of the present invention, when the covered bridge 140 corresponding to the right boarding and alighting entrance 110a is fully deployed when in use. The second bridge 143b and the third bridge 143c are fully deployed in the extension direction relative to the first bridge 143a. In this state, as described below, in order to support the front end of the covered bridge 140, the support leg 172 extends from the storage portion 171 of the top support jack 170 relative to the floor surface in the pit 160.

[0059] When the driving simulator 100 is used, the corridor 140 is retracted and stored toward the platform 150 in the reverse order of the extension and deployment of the corridor 140 toward the cockpit 110. In addition, the corridor 140 corresponding to the left entrance 110b is also extended and retracted in the same manner as described above.

[0060] In addition, in the present embodiment, the corridor bridges 140 are stored in a nested structure, but are not limited to this. The corridor bridge having a bridge of the same length as the distance from the platform 150 to the cockpit 110 may also be a pop-up bridge that is popped up and located above the platform 150 and becomes stationary. In addition, instead of popping up, it may be a rotating bridge whose front end draws an arc track when viewed from above and rotates toward the platform 150 to become stationary. In addition, the integrally constructed bridge may also move directly to the vicinity of the cockpit 110, and also directly return to the platform 150.

[0061] In this way, the corridor bridge 140 is stored in a nested structure and unfolded in the extension direction. Further, the support leg 172 as described above is provided at the front end of the corridor bridge 140. Thus, the corridor bridge 140 can be extended toward the cockpit 110 without being hindered by the actuators 121a, 121b, 121c, hydraulic pipes, etc. along the floor surface of the pit 160. Therefore, the corridor bridge 140 can be hung on the cockpit 110 and removed regardless of the state of the floor surface on which the driving simulator is installed.

[0062] In addition, as described above, if the corridor bridge is stored in a pop-up or rotating manner, it is not necessary to make the bridge portion of the corridor bridge into a nested structure, and the corridor bridge can be hung on the cockpit 110 with a simple mechanism. In addition, in the case where the integrally structured bridge itself directly moves to the vicinity of the cockpit 110 and directly returns to the platform 150, the same effect can be obtained.

[0063] <Jack support>

[0064] Figure 5 (a) and Figure 5 (b) is an enlarged perspective view showing details of the top support jack 170 of the covered bridge 140 according to the embodiment of the present invention.

[0065] Figure 5(a) is an enlarged stereoscopic view showing a state in which the support leg 172 of the supporting jack 170, which is a retractable support device of the corridor bridge 140, is stored in the storage section 171. As described above, the support leg 172 maintains the state of being stored in the storage section 171 until the corridor bridge 140 is fully unfolded. The support leg 172 has a leg portion 172a composed of a ball screw. A jack motor 173 is installed on a drive shaft 174 for retracting the support leg 172 via a gear (not shown). As a result, when the jack motor 173 does not rotate, the support leg 172 can remain stationary relative to the storage section 171 through the friction between the leg portion 172a and the storage section 171, and the friction between the gear of the jack motor 173 and the drive shaft 174. In addition, the jack motor 173 can be kept powered on, and the holding torque of the jack motor 173 can be used to maintain the stationary state.

[0066] Figure 5 (b) is an enlarged stereoscopic view showing a state in which the support leg 172 is extended and reaches the floor surface in the pit 160 from the storage section 171. When the corridor bridge 140 is unfolded, the jack motor 173 starts to rotate from the aforementioned static state, and the driving force is transmitted to the gear, the drive shaft 174, and the leg 172a. As a result, the ball screw, i.e., the support leg 172, extends from the storage section 171 to the floor surface in the pit. The support leg 172 has a foot 172b, and when the foot 172b contacts the floor surface in the pit, the jack motor 173 stops rotating. The support leg 172 remains stationary relative to the storage section 171 through the meshing friction between the ball screw, i.e., the leg 172a, and the storage section 171 cut with an internal thread corresponding to the ball screw. Therefore, the corridor bridge 140 is supported by the support leg 172. Thus, the free end side, i.e., the front end portion, of the cantilever beam, i.e., the corridor bridge 140, is supported and fixed, and the corridor bridge 140 does not bend or twist, and the driver can safely approach the cockpit 110 using the corridor bridge 140, and can also safely board. Moreover, since the leg portion 172a is composed of a ball screw, the leg portion 172a can quickly respond to the rotation of the jack motor 173 and quickly extend and retract. In addition, as described above, the state of powering the jack motor 173 can also be maintained, and the holding torque of the jack motor 173 can be used to hold the extended support leg 172.

[0067] As mentioned above, in the present embodiment, the top support jack 170 having a ball screw, i.e., the support leg 172, is used, but the support leg is not limited thereto. For example, a trapezoidal screw or a worm gear may also be used. In addition, the support device may be such that the support leg is foldable and is folded when the support leg is stored. In addition, the top support jack 170 may also be composed of a hydraulic jack. Even when such a support device is used, the support leg can be quickly extended and retracted.

[0068] <Bridge left and right movement mechanism>

[0069] Figure 6 (a) is a schematic plan view showing a right boarding and alighting entrance 110a of a cockpit 110 according to an embodiment of the present invention, that is, a position of a corridor corresponding to a right steering wheel. Figure 6 (b) means Figure 6 (a) is an enlarged perspective view of the front end of the covered bridge, Figure 6 (c) is an enlarged stereoscopic view of the mechanism for moving the corridor bridge left and right, showing the state of the corridor bridge before it moves to the left. Figure 2 In (a) and (b), it refers to the left side and the right side of the center line L1 of the base 180, respectively.

[0070] like Figure 6 As shown in (a), when the cockpit 110 is a right-side steering wheel, when looking down at the third bridge 143c, the boarding and alighting opening 141a of the corridor bridge 140 opens to the left. Thus, the driver can board and alight from the cockpit 110 using the boarding and alighting opening 141a and the right boarding and alighting opening 110a opened on the right side of the cockpit 110.

[0071] In addition, the corridor 140 is provided with a top jack displacement plate 144 at the front end. The top jack displacement plate 144 allows the top jack 170 to rotate within a plane including the top jack displacement plate 144, and the support leg 172 of the top jack 170 can avoid the actuator, hydraulic pipe, etc. laid along the floor surface of the pit 160 and contact the floor surface of the pit 160.

[0072] like Figure 6 As shown in (b), when the cockpit 110 is for the right steering wheel, the front end safety grid 146a is lower on the right side than on the left side when viewed from the front in order to avoid the rearview mirror on the right side of the cockpit 110. In addition, the opening closing safety grid 146b is embedded on the right side of the third bridge 143c, and the boarding and alighting opening 141a is opened on the left side of the third bridge 143c.

[0073] like Figure 6 As shown in (c), the corridor 140 has a left-right moving mechanism 190 of the corridor on the side of the entrance door 142. The left-right moving mechanism 190 is composed of a left-right moving steering wheel 191 for moving the corridor 140, a left-right moving trapezoidal screw 192 for transporting the corridor 140 to either the left or right, and a left-right moving linear guide 193 as a guide when the corridor 140 moves left or right on the platform 150. In addition, as for a more detailed structure, Figure 7 (a) and (b) are explained through items.

[0074] When the corridor bridge 140 is delivered to the cockpit 110 for the right steering wheel, the corridor bridge 140 is located on the right side on the base 180 .

[0075] Among them, the cockpit 110 is replaced with a cockpit corresponding to the left steering wheel. When boarding or alighting from the left boarding and alighting entrance 110b opened to the left of the cockpit 110, the left-right moving mechanism 190 is used to move the corridor 140 to the left side of the base 180.

[0076] Figure 7 (a) is an enlarged perspective view showing the detailed structure of the left-right moving mechanism 190 according to the embodiment of the present invention, and shows a state where the covered bridge 140 has moved to the left. Figure 7 (b) is an enlarged cross-sectional view showing the detailed structure of the left-right moving mechanism 190 according to the embodiment of the present invention.

[0077] like Figure 7 As shown in (a), the left-right moving mechanism 190 comprises: a manual clamp 194, which is tightened after the bridge moves to fix the rotating shaft 195 between the steering wheel 191 for left-right movement and the ball screw 192 for left-right movement; the rotating shaft 195, which transmits the rotation of the steering wheel 191 for left-right movement to the lower equal-diameter bevel gear 196; and the equal-diameter bevel gear 196, which converts the rotation of the steering wheel 191 for left-right movement into a right-angle direction, and converts it into the rotation of the trapezoidal screw 192 for left-right movement.

[0078] like Figure 7 As shown in (b), the trapezoidal screw 192 for left-right movement includes a left stopper 197a, a right stopper 197b, and a nut 198 for positioning the nut 198 of the trapezoidal screw 192 for left-right movement against the connecting member 199 of the gallery 140. The trapezoidal screw 192 for left-right movement is engaged with the gallery 140 via the connecting member 199. Thus, in addition to the above-mentioned structure, the left-right moving mechanism 190 also includes a manual clamp 194, a rotating shaft 195, a bevel gear 196, a left stopper 197a, a right stopper 197b, a nut 198, and a connecting member 199.

[0079] For example, by manually rotating the left-right moving steering wheel 191 counterclockwise, the rotating shaft 195 rotates, and the rotation is converted into a right-angle rotation by the miter gear 196, so that the left-right moving trapezoidal screw 192 rotates, and the gallery 140 engaged with the connecting member 199 by the trapezoidal screw 192 moves to the left side of the base 180 along the left-right moving linear guide 193. At this time, the connecting member 199 hits the left stopper 197a, so that the gallery 140 stops. After the gallery 140 stops moving, the manual clamp 194 is tightened to fix the rotating shaft 195. In this way, the gallery 140 can be prevented from moving left and right.

[0080] In addition, by manually rotating the steering wheel 191 for moving left and right, the gallery bridge 140 can be moved to the left side of the base 180, thereby the left and right movement of the platform 150 can be realized by a simple structure. In addition, owing to the use of a trapezoidal screw, compared with the situation of using a ball screw, it is possible to reduce costs. And, compared with the situation of using a triangular screw, the friction force is low and the feed spacing is small, so when manually rotating the steering wheel 191 for moving left and right, it is possible to rotate with less force. But the rotation of the steering wheel 191 for moving left and right is not limited to manual, and by utilizing the left and right moving motor to rotate the trapezoidal screw 192 for moving left and right, the gallery bridge 140 can also be automatically and rapidly moved to the left and right of the base 180.

[0081] In order to correspond to the left boarding and alighting gate 110b, the front end safety gate 146a of the corridor 140 is temporarily removed and reinstalled at the front end of the corridor 140 after the front and back are replaced (see Figure 8 (b)). In addition, the safety gate 146b for opening sealing is removed and installed in a manner to block the boarding and alighting opening 141a (refer to Figure 8 (b)). Thus, by simply replacing the front end safety gate 146a and the opening closing safety gate 146b of the corridor 140, the opening of the corridor 140 can be made to correspond to the right boarding and alighting entrance 110a and the left boarding and alighting entrance 110b of the cockpit 110, respectively.

[0082] Figure 8 (a) is a schematic plan view showing the left boarding and alighting entrance 110b of the cockpit 110 according to the embodiment of the present invention, that is, the position of the corridor 140 corresponding to the left steering wheel. Figure 8 (b) means Figure 8 (a) is an enlarged perspective view of the front end of the covered bridge 140, Figure 8 (c) is an enlarged perspective view showing the left-right moving mechanism 190 for moving the gallery 140 located on the left side of the base 180 to the right side.

[0083] like Figure 8 As shown in (a), when the cockpit 110 is a left-side steering wheel, the boarding and alighting opening 141b of the corridor bridge 140 is opposite to the boarding and alighting opening 141a described above and is opened on the right side of the third bridge 143c. Thus, the driver can board and alight to the cockpit 110 using the boarding and alighting opening 141b and the left boarding and alighting opening 110b opened on the left side of the cockpit 110.

[0084] like Figure 8As shown in (b), when the cockpit 110 is a left-side steering wheel, the front end safety grid 146a is lower on the left side than on the right side when viewed from the front in order to avoid the rearview mirror on the left side of the cockpit 110. In addition, the opening closing safety grid 146b is embedded in the left side of the third bridge 143c, and the opening 141b for boarding and alighting is opened on the right side of the third bridge 143c.

[0085] like Figure 8 As shown in (c) of FIG. 1 , similarly to the above, the corridor 140 includes a left-right moving mechanism 190 for the corridor on the entrance door 142 side.

[0086] When the corridor bridge 140 is delivered to the cockpit 110 of the left steering wheel, as described above, the corridor bridge 140 moves leftward on the base 180 .

[0087] Among them, the cockpit 110 is replaced with a right-side steering wheel. When boarding or alighting from the right boarding and alighting entrance 110a opened to the right side of the cockpit 110, the left-right moving mechanism 190 is used to move the corridor 140 to the right side of the base 180 in the opposite manner to the above.

[0088] The movement of the bridge 140 to the right is opposite to the above, and is achieved by rotating the left-right moving steering wheel 191 clockwise, thereby the left-right moving trapezoidal screw 192 transports the bridge 140 to the right side of the base 180. At this time, the bridge 140 moves to the right side of the base 180 along the left-right moving linear guide 193.

[0089] In order to correspond to the right boarding and alighting entrance 110a, the front end safety barrier 146a of the corridor 140 is temporarily removed and reinstalled to the corridor 140 after the front and back are reversed (see Figure 5 (b)). In addition, the safety gate 146b for closing the opening near the front end of the corridor bridge 140 is removed and installed in a manner to block the opening 141b for boarding and alighting (see Figure 5 (b)).

[0090] In this way, one corridor 140 can be moved to the right and left sides of the base 180 by the left-right moving mechanism 190. Thus, depending on whether the cockpit 110 has a right-hand steering wheel or a left-hand steering wheel, it can correspond to different right and left entrances 110a and 110b, and passengers can board and alight from different right and left entrances 110a and 110b using one corridor 140.

[0091] <Other Implementation Methods>

[0092] Fig. 9 (a) and Fig. 9(b) is a schematic top view of another embodiment of the corridor bridge 240 of the present invention. In this embodiment, the cockpit 110 stops in a manner such that the center reaches the extension line of the center line L2 when viewed from above the base 280, and the stop position is the same even when the cockpit 110 corresponds to the right steering wheel or the left steering wheel.

[0093] Fig. 9 (a) shows another embodiment of the present invention, in which a corridor bridge 240 is located on the right side of the cockpit 110 corresponding to the cockpit 110 with a right steering wheel.

[0094] Fig. 9 (b) shows another embodiment of the present invention, in which the corridor bridge 240 is located on the left side of the cockpit 110 corresponding to the cockpit 110 with a left steering wheel.

[0095] Structures having names corresponding to those related to the aforementioned covered bridge 140 have the same functions, and thus detailed descriptions thereof are omitted.

[0096] like Fig. 9 (a) and Fig. 9 As shown in (b), the base 280 to which the gallery bridge 240 is fixed has a width wider than the base 180 described above when viewed from above. Fig. 9 Corresponding to the cockpit 110 with the right steering wheel shown in (a), the corridor bridge 240 located on the right side of the cockpit 110 can move the entire width of the base 280 to the left using the left-right moving mechanism 290 as described above. Fig. 9 (a) and (b) refer to the left and right sides of the center line L2 of the base 280, respectively.

[0097] In addition, Fig. 9 Corresponding to the cockpit 110 with the left steering wheel shown in (b), the corridor bridge 240 located on the left side of the cockpit 110 can also use the left-right moving mechanism 290 to move the entire width of the base 280 to the right.

[0098] Therefore, the cockpit 110 having the same stop position when corresponding to the right-hand steering wheel and the left-hand steering wheel can correspond to the right boarding and alighting entrance 110a and the left boarding and alighting entrance 110b through one corridor 240 .

[0099] In the above description, the cockpit 110 has a left and right boarding and alighting ports, and the cockpit 110 is replaced to correspond to the right and left steering wheels, but the present invention is not limited thereto. For example, the boarding and alighting ports of the cockpit may be only on the right or left side (in this case, they are interchangeable), or the steering wheels may be located on the left and right sides of a cockpit, and the boarding and alighting ports may also be located on the left and right sides accordingly.

[0100] According to the above-described configuration, it is possible to provide a boarding and alighting device that allows passengers to board and alight from different left and right boarding and alighting entrances of a driving simulator via a single corridor.
