Description

Technical Field

[0001] The present invention relates to a vehicle with a loading platform provided on the vehicle, which includes a loading platform.

Background Art

[0002] Conventionally, as described in Patent Document 1, a loading platform lifting device having a loading platform mounted on the rear of a vehicle and used for loading and unloading goods and stored below the loading box of the vehicle is known. The loading platform lifting device includes a loading platform, a control unit that performs a pulling-out control for pulling out the loading platform to the rear side of the vehicle and a lowering control for lowering the pulled-out loading platform, an operation unit that outputs a pulling-out signal for pulling out the loading platform, and a sensor that detects the loading platform pulled out to a predetermined position and outputs a detection signal to the control unit. When the sensor detects the loading platform at the predetermined position, the control unit restricts the movement of the pulled-out loading platform based on the pulling-out signal of the operation unit despite the continuous input of the pulling-out signal.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the loading platform lifting device described in Patent Document 1, for example, if there is a sensor malfunction such as a failure or false detection, the sensor may not detect the loading platform in its predetermined position even though it is in that position, and a pull-out signal may be output. In such cases, the loading platform being used as a step may move, which is dangerous. This problem is not limited to when the loading platform is pulled out while being used as a step, but also occurs when it is retracted.

[0006] Therefore, the present invention aims to provide a vehicle equipped with a safe loading platform. [Means for solving the problem]

[0007] The vehicle with a loading platform of the present invention comprises a vehicle body having a frame, a mounting section mounted on the frame, a loading platform drive device for loading and unloading cargo onto the mounting section, and a control device for controlling the loading platform drive device, wherein the mounting section comprises a loading platform on which cargo is placed, and an opening / closing section provided to open and close relative to the loading platform, and the loading platform drive device comprises a loading platform on which cargo is placed, the loading platform being movable between a storage position stored below the loading platform and an extended position extended horizontally around the mounting section, and the loading platform The control device comprises a drive unit that moves the opening / closing unit between the storage position and the deployed position, and raises and lowers it relative to the loading platform in the deployed position, and the control device comprises a detection unit that has a detection function to detect at least one of the opening operation from closed to open and the closing operation from open to closed of the opening / closing unit, and a control unit that performs corresponding control to drive the drive unit to move the loading platform based on the detection result of the detection unit, and after the detection unit detects the opening operation or the closing operation of the opening / closing unit, the detection unit stops the detection function of the detection unit.

[0008] With this configuration, the detection function is stopped by the detection stop control, so the detection unit does not falsely detect the opening or closing of the opening / closing part. Therefore, the loading platform can be used safely.

[0009] Furthermore, the system may also be configured to include a power supply unit that supplies power to the detection unit, the detection unit operating on power supplied from the power supply unit, and the detection stop control being a control that cuts off the power supply from the power supply unit to the detection unit.

[0010] With this configuration, the power supply to the detection unit is cut off by the detection stop control, preventing the detection unit from making false detections. Therefore, it is possible to prevent the drive unit from moving the loading platform based on false detections.

[0011] Furthermore, the detection unit may also include a signal transmission function that, as a detection function, transmits a detection signal to the control unit when it detects the opening or closing of the opening / closing unit, the control unit performs the corresponding control when it receives the detection signal, and the detection stop control is a control that disables the signal transmission function.

[0012] With this configuration, the signal transmission function is disabled by the detection stop control, so the detection unit does not erroneously detect the opening or closing of the opening / closing part and output the result to the control unit. Therefore, it is possible to prevent the drive unit from moving the loading platform based on an erroneous detection.

[0013] Furthermore, the control unit may be configured to perform the detection stop control while the corresponding control is being completed.

[0014] With this configuration, detection stop control is performed before the corresponding control is completed, thus preventing the drive unit from moving the loading platform based on false detection when using the loading platform.

[0015] Furthermore, the control unit may be configured to perform the detection stop control and then perform the corresponding control after detecting that the detection function has been stopped.

[0016] With this configuration, response control is performed only after it has been confirmed that detection stop control has been executed. Therefore, if, for example, detection stop control cannot be executed due to a malfunction in the control device, response control will not be performed. Thus, even if the detection unit continues to detect, it is possible to prevent the drive unit from being driven.

[0017] Furthermore, the control unit may be configured to execute a non-execution control, which does not execute the corresponding control, if the detection unit detects the opening or closing operation of the opening / closing unit and a predetermined time has elapsed since then, but the detection stop control is not executed.

[0018] With this configuration, for example, if there is a malfunction in the control device, such as a malfunction in the detection stop control, and the detection function is not stopped, non-execution control is performed. Therefore, even if detection results continue to be output when detection stop control is not performed, the loading platform will not be moved. Thus, the loading platform can be used safely.

[0019] Furthermore, the detection unit may include a signal transmission function that, as part of its detection function, transmits a detection signal to the control unit when it detects the opening or closing of the opening / closing unit, and the control unit may be configured to execute the non-execution control when it continuously receives signals from the detection unit for a predetermined period of time.

[0020] With this configuration, if a detection signal is received continuously for a predetermined period of time, non-execution control is performed. For example, if detection stop control is not performed, the loading platform will not be moved even if a detection signal continues to be output as a detection result. Therefore, the loading platform can be used safely. [Effects of the Invention]

Embodiments for Carrying Out the Invention

[0023] The vehicle 1 with a loading platform according to an embodiment of the present invention will be described with reference to FIGS. 1 to 11. For the sake of convenience of explanation, the front-rear direction and the up-down direction will be described based on the directions shown in FIG. 2.

[0024] As shown in FIGS. 1 and 2, the vehicle 1 with a loading platform includes a vehicle body having a frame portion 11 disposed at the front end and having a cab (not shown) with a driver's seat, a chassis frame extending rearward from the cab, a mounting portion 2 mounted on the frame portion 11, a loading platform driving device 3 provided on the frame portion 11, a control device 4 for controlling the loading platform driving device 3, and a power supply unit 5.

[0025] As shown in Figure 1, the bodywork 2 comprises a cargo bed 21 on which cargo can be placed, and an opening / closing section 22 that is provided to open and close relative to the cargo bed 21. In this embodiment, the bodywork 2 is a cargo box, and the bottom of the cargo box constitutes the cargo bed 21. The opening / closing section 22 is a door provided at the rear end of the cargo box, and in this embodiment, it is a double door that opens toward the rear. The bodywork 2 is also provided on the upper part of the frame section 11, and the cargo bed 21 extends horizontally above the frame section 11.

[0026] As shown in Figure 2, the loading platform drive device 3 comprises a loading platform 31 and a drive unit 32 that moves the loading platform 31 relative to the frame 11. The loading platform 31 comprises a main plate 311 provided at the rear end of the drive unit 32, a sub-plate 312 that is foldable and unfoldable and connected to the main plate 311, and a connecting part 313 that connects the main plate 311 and the sub-plate 312. The connecting part 313 has a hinge (not numbered) at one end that is rotatably connected to the front end of the main plate 311 and at the other end that is rotatably connected to the base end of the sub-plate 312. When stored, the loading platform 31 is in a folded state with the sub-plate 312 folded onto the main plate 311. When in use, as shown in Figure 5, the sub-plate 312 is unfolded, so that the loading platform 31 is in an unfolded state in which a continuous loading surface is formed from the upper surface of the main plate 311 to the upper surface of the sub-plate 312.

[0027] The drive unit 32 includes a slide rail 34 that is suspended from the frame 11 via a bracket 33 and extends in the front-rear direction, a front-rear drive unit 35 provided on the slide rail 34, and a lifting drive unit 36 ​​provided on the front-rear drive unit 35. A loading platform 31 is connected to the lifting drive unit 36. The slide rail 34 extends in the front-rear direction along the frame 11 below the frame 11. Furthermore, the front-rear drive unit 35 and the lifting drive unit 36 ​​are located below the slide rail 34.

[0028] The front-rear drive unit 35 is provided so as to be movable in the front-rear direction along the slide rail 34. Specifically, the front-rear drive unit 35 includes a hydraulic cylinder 351 with one end connected to the frame 11, and as the hydraulic cylinder 351 extends and retracts, the front-rear drive unit 35 moves along the slide rail 34 relative to the frame 11.

[0029] The lifting drive unit 36 ​​has a lifting mechanism 37, the front end of which is connected to the front / rear drive unit 35 and the rear end of which is connected to a loading platform 31. The lifting drive unit 36 ​​also moves in the front / rear direction relative to the frame unit 11 in conjunction with the front / rear drive unit 35.

[0030] The lifting mechanism 37 includes an auxiliary link 371 rotatably attached to the front-rear drive unit 35 within a certain range, and an upper arm 372 and a lift cylinder 373 rotatably attached to the auxiliary link 371. The tip of the lift cylinder 373 is connected to a predetermined position on the upper arm 372, and torque is applied to the upper arm 372 by its extension and retraction operation. The lifting mechanism 37 also includes a lower arm 374 rotatably attached to the front-rear drive unit 35. The lift cylinder 373 is, for example, a single-acting hydraulic cylinder. The upper arm 372 and the lower arm 374 constitute a parallel link in which the rectangle connecting their fulcrum and point of application is a parallelogram, and the extension and retraction operation of the lift cylinder 373 causes their tip sides to move up and down.

[0031] In this load-receiving platform drive device 3, the front and rear drive unit 35 moves in the front and rear direction along the slide rail 34. As shown in Figure 2, the load-receiving platform 31 moves between a stored position P1 where it is stored below the loading platform 21, and an extended position P3 where it is deployed horizontally around the loading platform 21 (rearward in this embodiment), as shown in Figure 4. Also, as shown in Figure 3, during the movement between the stored position P1 and the extended position P3, the load-receiving platform drive device 3 reaches an extended position P2 where a part of the load-receiving platform drive device 3 is positioned around the loading platform 21. In the extended position P2 of this embodiment, a part of the load-receiving platform 31 is positioned horizontally around the loading platform 21, and the other part of the load-receiving platform 31 is positioned below the loading platform 21.

[0032] Furthermore, as shown in Figure 5, the loading platform drive unit 3 in the deployed position P3 raises and lowers the loading platform 31 by driving the lifting drive unit 36, allowing the loading platform 31 to move between a raised position (indicated by a dashed line) where the floor surface of the cargo box (not shown) and the loading surface are at approximately the same height, and a grounded position (indicated by a solid line) where it is in contact with the ground. This allows loading and unloading of cargo onto the loading platform 21 by raising and lowering the loading platform 31 at the rear of the cargo box. Note that the loading platform 31 in the extended position P2 is located between the raised position and the installed position in the vertical direction.

[0033] As shown in Figure 6, the control device 4 includes a detection unit 41 that detects opening operations to open the opening / closing unit 22 from closed and closing operations to close the opening / closing unit 22 from open, a control unit 42 that controls the driving of the loading platform drive device 3 based on the detection by the detection unit 41, and an operation unit 45 in which the operator inputs operations to drive the loading platform 31. The operation unit 45 is composed of, for example, a remote control or a switch located outside the vehicle, and can input operations to move the loading platform 31 in the forward and backward directions and to raise and lower the loading platform 31.

[0034] The detection unit 41 includes a first detection unit 43 that has a detection function to detect an opening operation of the opening / closing unit 22 from closed to open and output the detection result to the control unit 42, and a second detection unit 44 that has a detection function to detect a closing operation of the opening / closing unit 22 from open to closed and output the detection result to the control unit 42.

[0035] The first detection unit 43 includes a first sensor unit 431 that detects the opening operation of the opening / closing unit 22, and a first signal unit 432 that has a signal transmission function that transmits a detection signal to the control unit 42 when the first sensor unit 431 detects the opening operation. In this embodiment, the first detection unit 43 is configured such that the first sensor unit 431 and the first signal unit 432 operate on the same power supply.

[0036] As shown in Figure 1, the first sensor unit 431 is positioned near (for example, above) the opening / closing unit 22 and is a sensor that detects the movement of the opening / closing unit 22 in conjunction with the opening operation without contact. Specifically, the first sensor unit 431 is a proximity sensor and detects when the opening / closing unit 22 passes below the first sensor unit 431 due to the opening operation. Note that the first sensor unit 431 is not limited to this configuration and can be composed of various sensors capable of detecting the opening operation.

[0037] As shown in Figure 6, the first signal unit 432 continuously emits a detection signal as a detection result when the first sensor unit 431 detects the passage of the opening / closing unit 22 due to its opening operation. In this embodiment, the first signal unit 432 continuously emits a detection signal after the first sensor unit 431 detects the passage of the opening / closing unit 22 until the power supply is cut off.

[0038] The second detection unit 44 includes a second sensor unit 441 that detects the closing operation of the opening / closing unit 22, and a second signal unit 442 that has a signal transmission function. In this embodiment, the second detection unit 44 is configured such that the second sensor unit 441 and the second signal unit 442 operate on the same power supply.

[0039] As shown in Figure 1, the second sensor unit 441 is positioned near (for example, above) the opening / closing unit 22 and is a sensor that detects the movement of the opening / closing unit 22 in conjunction with the closing operation without contact. Specifically, the second sensor unit 441 is a proximity sensor and detects when the opening / closing unit 22 passes below the second sensor unit 441 due to the closing operation. Note that the second sensor unit 441 is not limited to this configuration and can be composed of various sensors capable of detecting the opening operation.

[0040] As shown in Figure 6, the second signal unit 442 continuously emits a detection signal when the power is on until the second sensor unit 441 detects the passage of the opening / closing unit 22 due to its closing operation. That is, when the second sensor unit 441 detects the passage of the opening / closing unit 22 due to its closing operation, the second signal unit 442 stops transmitting the detection signal as a result of the detection. In this embodiment, the second signal unit 442 does not emit a detection signal until the power supply is cut off once after the second sensor unit 441 detects the passage of the opening / closing unit 22, and then until the power supply is stopped.

[0041] The control unit 42 performs corresponding control to drive the load receiving platform drive device 3 based on the detection result from the detection unit 41. The control unit 42 also controls the power supply unit 5, which will be described later, to control the power supply to the first detection unit 43 and the second detection unit 44. Specifically, the control unit 42 performs the open operation corresponding control S1 shown in Figure 7 and the closed operation corresponding control S2 shown in Figure 8 based on the input from the detection unit 41. Details of the open operation corresponding control S1 and the closed operation corresponding control S2 will be described later.

[0042] The power supply unit 5 comprises a first power supply unit 51 that supplies power to the first detection unit 43 and a second power supply unit 52 that supplies power to the second detection unit 44. In this embodiment, the power supply unit 5 is configured to supply power to the first detection unit 43 and the second detection unit 44 from the vehicle's battery (not shown). The first power supply unit 51 supplies power from the battery to the first detection unit 43 and / or cuts off the power supply, and the second power supply unit 52 supplies power from the battery to the second detection unit 44 and cuts off the power supply. Furthermore, the power supply unit 5 is controlled by the control unit 42 to supply power to the first detection unit 43 and the second detection unit 44 and to cut off the power supply. Note that the power supply unit 5 is not limited to a configuration that supplies power to the first detection unit 43 and the second detection unit 44 from the vehicle's battery.

[0043] Next, the corresponding control will be explained with reference to Figures 7 to 11. The corresponding control includes the opening operation corresponding control S1 shown in Figure 7 and the closing operation corresponding control S2 shown in Figure 8. First, the opening operation corresponding control S1 will be explained with reference to Figure 7.

[0044] The opening operation response control S1 is a control for pulling out the loading platform 31 from the storage position P1 to the extended position P2 when an opening operation is performed on the opening / closing section 22. Specifically, the opening operation response control S1 includes (1-1) first detection signal confirmation control S11, (1-2) first detection stop control S12, (1-3) second detection start control S13, (1-4) first confirmation control S14, (1-5) pull-out control S15, (1-6) pull-out timer control S16, (1-7) pull-out stop control S17, (1-8) first restart control S18, and (1-9) non-execution control S19.

[0045] (1-1) The first detection signal confirmation control S11 is a control that confirms that a detection signal has been received from the first detection unit 43. In this embodiment, when a detection signal is received from the first detection unit 43, it is determined that the opening / closing unit 22 has opened. In the first detection signal confirmation control S11, the control unit 42 repeats the first detection signal confirmation control S11 until it receives a detection signal from the first detection unit 43 (NO in the first detection signal confirmation control S11), and when it receives a detection signal from the first detection unit 43, it proceeds to the first detection stop control S12 (YES in the first detection signal confirmation control S11).

[0046] (1-2) The first detection stop control S12 is a control that stops the detection function of the first detection unit 43. In the first detection stop control S12 of this embodiment, the detection function of the first detection unit 43 is stopped by stopping the operation of both the first sensor unit 431 and the first signal unit 432. Specifically, the first detection stop control S12 controls the first power supply unit 51 to cut off the power supply to the first detection unit 43. When the power supply is cut off, the detection function of the first detection unit 43 is stopped. In other words, the first detection stop control S12 puts the first sensor unit 431 in a state where it cannot detect the opening operation of the opening / closing unit 22, and puts the first signal unit 432 in a state where it cannot transmit a detection signal.

[0047] (1-3) The second detection start control S13 is a control that starts the detection function of the second detection unit 44. In the second detection start control S13 of this embodiment, the detection function of the second detection unit 44 is started by starting the operation of both the stopped second sensor unit 441 and the second signal unit 442. Specifically, the second detection stop control S22 controls the second power supply unit 52 to start supplying power to the second detection unit 44. The detection function of the second detection unit 44 is started when the power supply is started.

[0048] (1-4) The first confirmation control S14 is a control that confirms that the detection function of the first detection unit 43 has been stopped by the first detection stop control S12. Specifically, the first confirmation control S14 includes the first timer control S141, the first signal confirmation control S142, and the first power supply confirmation control S143.

[0049] The first timer control S141 is a control that confirms that a predetermined time has elapsed since the detection signal was received in the first detection signal confirmation control S11. The predetermined time in the first timer control S141 is the amount of time required for the first detection unit 43 to stop its detection function by performing the first detection stop control S12. In the first timer control S141, if the predetermined time has elapsed, the system proceeds to the first signal confirmation control S142 (YES in the first timer control S141), and if the predetermined time has not elapsed, the system proceeds back to the first timer control S141 (NO in the first timer control S141).

[0050] The first signal confirmation control S142 is a control that confirms that the first detection unit 43 has stopped transmitting detection signals. In the first signal confirmation control S142, the control unit 42 checks whether or not it has received a detection signal from the first detection unit 43. If it has not received a detection signal, it determines that the first detection unit 43 has stopped transmitting detection signals. If it has received a detection signal, it determines that the first detection unit 43 has not stopped transmitting detection signals. For example, if the first detection unit 43 has not stopped transmitting detection signals, the detection function of the first detection unit 43 may not have been stopped in the first detection stop control S12. In the first signal confirmation control S142, if it is confirmed that the first detection unit 43 has stopped transmitting detection signals, the control proceeds to the first power supply confirmation control S143 (YES in the first signal confirmation control S142). If the first detection unit 43 has not stopped transmitting detection signals, the control proceeds to the non-execution control S19 (NO in the first signal confirmation control S142).

[0051] The first power supply confirmation control S143 is a control that confirms that the power supply to the first detection unit 43 is OFF. In the first power supply confirmation control S143, the control unit 42 checks the operating status of the first power supply unit 51 and determines that the power supply to the first detection unit 43 is OFF if the first power supply unit 51 is not supplying power to the first detection unit 43, and determines that the power supply to the first detection unit 43 is ON if the first power supply unit 51 is supplying power to the first detection unit 43. Cases in which the power supply to the first detection unit 43 is ON include, for example, when the power supply to the first detection unit 43 was not cut off in the first detection stop control S12, or when the power supply to the first detection unit 43 was cut off in the first detection stop control S12, but was subsequently restored due to some influence. In this embodiment, in the first signal confirmation control S142, if the detection signal is stopped, the first power supply confirmation control S143 is performed. Therefore, if the power supply to the first detection unit 43 is ON, it can be determined that the power supply to the first detection unit 43 was cut off in the first detection stop control S12, the transmission of the detection signal was stopped, and then the power supply to the first detection unit 43 was restarted. In the first power supply confirmation control S143, if it is confirmed that the power supply to the first detection unit 43 is OFF, the system proceeds to the withdrawal control S15 (YES in the first power supply confirmation control S143), and if the power supply to the first detection unit 43 is not OFF, the system proceeds to the non-execution control S19 (NO in the first power supply confirmation control S143).

[0052] (1-5) The pull-out control S15 controls the load-receiving platform drive unit 3 to pull out the load-receiving platform 31 from the storage position P1 to the outside of the loading platform 21 in the horizontal direction toward the deployed position P3. In the pull-out control S15 of this embodiment, the load-receiving platform 31 from the storage position P1 is pulled out to the extended position P2. Specifically, the pull-out control S15 controls the front and rear drive unit 35 of the drive unit 32 and drives the hydraulic cylinder 351 of the front and rear drive unit 35 to move the load-receiving platform 31 backward relative to the frame unit 11. In the pull-out control S15, the drive unit 32 is driven to pull out the load-receiving platform 31 until the pull-out stop control S17, which will be described later, is executed.

[0053] (1-6) The withdrawal timer control S16 is a control that confirms that a predetermined time has elapsed since the start of the withdrawal control S15. The predetermined time in the withdrawal timer control S16 is the time required from the start of the withdrawal control S15 until the load receiving platform 31 moves from the storage position P1 to the extension position P2 by the drive of the drive unit 32. In the withdrawal timer control S16, if the predetermined time has elapsed, the system transitions to the withdrawal stop control S17 (YES in the withdrawal timer control S16), and if the predetermined time has not elapsed, the system transitions back to the withdrawal timer control S16 (NO in the withdrawal timer control S16).

[0054] (1-7) The withdrawal stop control S17 is a control that stops the drive of the drive unit 32 and stops the operation of pulling the loading platform 31 outward relative to the loading platform 21. In this embodiment, after a predetermined time has elapsed since the start of the withdrawal control S15, it is determined that the loading platform 31 has been pulled out to the extended position P2, and the drive of the loading platform 31 is stopped. When the withdrawal stop control S17 is completed, the loading platform 31 is stopped at the extended position P2.

[0055] Through the above steps, when the opening / closing section 22 opens, the control to pull the loading platform 31 to the extended position P2 is completed. Subsequently, when the opening / closing section 22 closes and the opening / closing section 22 is in the closed state, the first restart control S18 is executed (1-8) to restart the detection function of the first detection unit 43. The first restart control S18 includes the first closing confirmation control S181 and the first detection restart control S182.

[0056] The first closing confirmation control S181 is a control that confirms that the opening / closing unit 22 has closed. In this embodiment, it is determined that the opening / closing unit 22 has closed when the transmission of a detection signal from the second detection unit 44 stops. In the first closing confirmation control S181, the control unit 42 repeats the first closing confirmation control S181 while it is receiving a detection signal from the second detection unit 44 (NO in the first closing confirmation control S181), and when the reception of a detection signal from the second detection unit 44 stops, it moves to the first detection restart control S182 (YES in the first closing confirmation control S181).

[0057] The first detection restart control S182 is a control that restarts the detection function of the first detection unit 43. In the first detection restart control S182 of this embodiment, the detection function of the first detection unit 43 is restarted by switching the first power supply unit 51 from a state in which power is cut off to a state in which power is supplied to the first detection unit 43. When power supply to the first detection unit 43 is restarted, the first detection unit 43 becomes capable of detecting the opening operation of the first sensor unit 431, and the first signal unit 432 does not transmit a detection signal until it detects the opening operation of the first sensor unit 431, and transmits a detection signal after it detects the opening operation of the first sensor unit 431.

[0058] As a result of the first restart control S18 described above, when the opening / closing unit 22 opens again, the first detection unit 43 can detect the opening operation and transmit a detection signal.

[0059] Furthermore, in the first signal confirmation control S142 and first power supply confirmation control S143 of the first confirmation control S14, if the first detection unit 43, which should have had its detection function stopped in the first detection stop control S12, is transmitting a detection signal or power is being supplied to the first detection unit 43, it is determined that the first detection stop control S12 has not been completed properly, and (1-9) non-execution control S19 is performed.

[0060] Non-execution control S19 is a control that does not extend the loading platform 31 based on the detection result of the first detection unit 43. In non-execution control S19, the loading platform drive device 3 is controlled so that the loading platform 31 does not move from the storage position P1, without performing any control to extend the loading platform 31 from the storage position P1. However, even when non-execution control S19 is performed, control to move the loading platform 31 by operating the operation unit 45 is still performed.

[0061] Furthermore, if non-execution control S19 is performed, notification control S191 is performed to inform the worker or other personnel that non-execution control S19 is being performed. Notification control S191 may include, for example, an error sound or an error display on a screen installed in the vehicle.

[0062] Next, with reference to Figure 8, the closing operation corresponding control S2 will be explained.

[0063] The closing operation response control S2 is a control for storing the loading platform 31 from the extended position P2 to the stored position P1 when the opening / closing section 22 is closed. Specifically, the closing operation response control S2 includes (2-1) second detection signal confirmation control S21, (2-2) second detection stop control S22, (2-3) first detection start control S23, (2-4) second confirmation control S24, (2-5) storage control S25, (2-6) storage timer control S26, (2-7) storage stop control S27, (2-8) second restart control S28, and (2-9) non-execution control S29.

[0064] (2-1) The second detection signal confirmation control S21 is a control that confirms the detection signal based on the detection result of the second detection unit 44. In this embodiment, the detection signal is continuously transmitted when the second detection unit 44 does not detect the closing operation of the opening / closing unit 22, and the transmission of the detection signal is stopped when the second detection unit 44 detects the closing operation of the opening / closing unit 22. Therefore, in the second detection signal confirmation control S21, the control unit 42 confirms that the reception of the detection signal from the second detection unit 44 has stopped. When the reception of the detection signal from the second detection unit 44 has stopped, it is determined that the opening / closing unit 22 has closed. In the second detection signal confirmation control S21, the control unit 42 repeats the second detection signal confirmation control S21 until the reception of the detection signal from the second detection unit 44 stops (NO in the second detection signal confirmation control S21), and when the reception of the detection signal from the second detection unit 44 has stopped, it moves to the second detection stop control S22 (YES in the second detection signal confirmation control S21).

[0065] (2-2) The second detection stop control S22 is a control that stops the detection function of the second detection unit 44. In the second detection stop control S22 of this embodiment, the detection function of the second detection unit 44 is stopped by stopping the operation of both the second sensor unit 441 and the second signal unit 442. Specifically, the second detection stop control S22 controls the second power supply unit 52 to cut off the power supply to the second detection unit 44. When the power supply is cut off, the detection function of the second detection unit 44 is stopped. In other words, the second detection stop control S22 puts the second sensor unit 441 in a state where it cannot detect the opening operation of the opening / closing unit 22, and puts the second signal unit 442 in a state where it cannot transmit a detection signal.

[0066] (2-3) The first detection start control S23 is a control that starts the detection function of the first detection unit 43. In the first detection start control S23 of this embodiment, the detection function of the first detection unit 43 is started by starting the operation of both the stopped first sensor unit 431 and the first signal unit 432. Specifically, in the first detection stop control S12, the first power supply unit 51 is controlled to start supplying power to the first detection unit 43. When the power supply is started, the detection function of the first detection unit 43 is started.

[0067] (2-4) The second confirmation control S24 is a control that confirms that the detection function of the second detection unit 44 has been stopped by the second detection stop control S22. Specifically, the second confirmation control S24 includes the second timer control S241, the second signal confirmation control S242, and the second power supply confirmation control S243.

[0068] The second timer control S241 is a control that confirms that a predetermined time has elapsed since the detection signal was received in the second detection signal confirmation control S21. The predetermined time in the second timer control S241 is the amount of time required for the second detection unit 44 to stop its detection function by performing the second detection stop control S22. In the second timer control S241, if the predetermined time has elapsed, the system proceeds to the second signal confirmation control S242 (YES in the second timer control S241), and if the predetermined time has not elapsed, the system proceeds back to the second timer control S241 (NO in the second timer control S241).

[0069] The second signal confirmation control S242 is a control that confirms that the second detection unit 44 has stopped transmitting detection signals. In the second signal confirmation control S242, the control unit 42 checks whether or not it has received a detection signal from the second detection unit 44. If it has not received a detection signal, it determines that the second detection unit 44 has stopped transmitting detection signals. If it has received a detection signal, it determines that the second detection unit 44 has not stopped transmitting detection signals. For example, a case in which the transmission of detection signals from the second detection unit 44 has not stopped is when the power supply to the second detection unit 44 is cut off in the second detection stop control S22, stopping the transmission of detection signals, and then the power supply to the second detection unit 44 is resumed due to some influence. In the second signal confirmation control S242, if it is confirmed that the second detection unit 44 has stopped transmitting detection signals, the control proceeds to the second power supply confirmation control S243 (YES in the second signal confirmation control S242). If the second detection unit 44 has not stopped transmitting detection signals, the control proceeds to the non-execution control S29 (NO in the second signal confirmation control S242).

[0070] The second power supply confirmation control S243 is a control that confirms that the power supply to the second detection unit 44 is OFF. In the second power supply confirmation control S243, the control unit 42 checks the operating status of the second power supply unit 52, and if the second power supply unit 52 is not supplying power to the second detection unit 44, it is determined that the power supply to the second detection unit 44 is OFF, and if the second power supply unit 52 is supplying power to the second detection unit 44, it is determined that the power supply to the second detection unit 44 is ON. Cases in which the power supply to the second detection unit 44 is ON include, for example, when the power supply to the second detection unit 44 was not cut off in the second detection stop control S22, or when the power supply to the second detection unit 44 was cut off in the second detection stop control S22, but was subsequently restored due to some influence. In this embodiment, in the second signal confirmation control S242, if the detection signal is stopped, the second power supply confirmation control S243 is performed. Therefore, if the power supply of the second detection unit 44 is ON, it can be determined that the power supply from the second power supply unit 52 to the second detection unit 44 was not cut off in the second detection stop control S22. In the second power supply confirmation control S243, if it is confirmed that the power supply of the second detection unit 44 is OFF, the system proceeds to the draw-out control S15 (YES in the second power supply confirmation control S243), and if the power supply of the second detection unit 44 is not OFF, the system proceeds to the non-execution control S29 (NO in the second power supply confirmation control S243).

[0071] (2-5) The storage control S25 controls the load receiving platform drive unit 3 to store the load receiving platform 31 from the extended position P2 towards the storage position P1, horizontally inside the load bed 21. In the storage control S25 of this embodiment, the load receiving platform 31 is moved from the extended position P2 to the storage position P1. Specifically, in the storage control S25, the front and rear drive unit 35 of the drive unit 32 is controlled, and the hydraulic cylinder 351 of the front and rear drive unit 35 is driven to move the load receiving platform 31 forward relative to the frame unit 11. In the storage control S25, the drive unit 32 is driven to pull out the load receiving platform 31 until the storage stop control S27, which will be described later, is executed.

[0072] (2-6) The storage timer control S26 is a control that confirms that a predetermined time has elapsed since the start of the storage control S25. The predetermined time in the storage timer control S26 is the time required from the start of the storage control S25 until the loading platform 31 moves from the extended position P2 to the stored position P1 by the drive of the drive unit 32. In the storage timer control S26, if the predetermined time has elapsed, the system transitions to the storage stop control S27 (YES in the storage timer control S26), and if the predetermined time has not elapsed, the system transitions back to the storage timer control S26 (NO in the storage timer control S26).

[0073] (2-7) The storage stop control S27 is a control that stops the drive of the drive unit 32 and stops the operation of storing the loading platform 31 inward relative to the loading platform 21. In this embodiment, after a predetermined time has elapsed since the start of the storage control S25, it is determined that the loading platform 31 has been stored to the storage position P1, and the drive of the loading platform 31 is stopped. When the storage stop control S27 is completed, the loading platform 31 is in a stopped state at the storage position P1.

[0074] Through the above steps, when the opening / closing section 22 is closed, the control to pull the loading platform 31 to the storage position P1 is completed. Subsequently, when the opening / closing section 22 is opened and the opening / closing section 22 is in the open state, (2-8) the second restart control S28 is executed to restart the detection function of the second detection unit 44. The second restart control S28 includes the second open confirmation control S281 and the second detection restart control S282.

[0075] The second open confirmation control S281 is a control that confirms that the opening / closing unit 22 has opened. In this embodiment, it is determined that the opening / closing unit 22 has opened when a detection signal is transmitted from the first detection unit 43. In the second open confirmation control S281, the control unit 42 repeats the second open confirmation control S281 as long as it does not receive a detection signal from the first detection unit 43 (NO in the second open confirmation control S281), and when it receives a detection signal from the first detection unit 43, it proceeds to the second detection restart control S282 (YES in the second open confirmation control S281).

[0076] The second detection restart control S282 is a control that restarts the detection function of the second detection unit 44. In the second detection restart control S282 of this embodiment, the detection function of the second detection unit 44 is restarted by switching the second power supply unit 52 from a state in which power is cut off to a state in which power is supplied to the second detection unit 44. When power supply to the second detection unit 44 is restarted, the second detection unit 44 becomes capable of detecting the closing operation of the second sensor unit 441, and the second signal unit 442 transmits a detection signal until the closing operation of the second sensor unit 441 is detected, and stops transmitting the detection signal after the closing operation of the second sensor unit 441 is detected.

[0077] As a result of the second restart control S28 described above, if the opening / closing unit 22 opens again, the second detection unit 44 can detect the opening operation and stop transmitting the detection signal.

[0078] Furthermore, in the second signal confirmation control S242 and second power supply confirmation control S243 of the second confirmation control S24, if the second detection unit 44, whose detection function should have been stopped in the second detection stop control S22, is transmitting a detection signal or power is being supplied to the second detection unit 44, it is determined that the second detection stop control S22 has not been completed properly, and (2-9) non-execution control S29 is performed.

[0079] Non-execution control S29 is a control that does not extend the loading platform 31 based on the detection result of the second detection unit 44. In non-execution control S29, the loading platform drive device 3 is controlled so that the loading platform 31 does not move from the extended position P2, without performing the control to retract the loading platform 31 from the extended position P2. Even when non-execution control S29 is performed, control to move the loading platform 31 by operating the operation unit 45 is still performed.

[0080] Furthermore, if non-execution control S29 is performed, notification control S291 is performed to inform the worker or other personnel that non-execution control S29 is being performed. Notification control S291 may include, for example, an error sound or an error display on a screen installed in the vehicle.

[0081] The opening operation control S1 and the closing operation control S2 are executed simultaneously. In the following explanation, we will use the case where the closed opening / closing section 22 is opened and then closed again as an example. In the timing charts of Figures 9 to 11, ON for the first detection unit 43 and the second detection unit 44 refers to the state in which a detection signal is transmitted, and OFF refers to the state in which a detection signal is not transmitted. First, referring to Figure 9, we will explain the case in which the loading platform 31 moves to the extended position P2 and moves to the stored position P1 in the opening operation control S1 and the closing operation control S2.

[0082] First, when the opening / closing section 22 is closed, the first detection section 43 is supplied with power from the first power supply section 51, but the first sensor section 431 does not detect the opening operation, and no detection signal is transmitted from the first signal section 432. Also, the second detection section 44 is not supplied with power from the second power supply section 52, and its detection function is stopped. Furthermore, in this state, the (1-1) first detection signal confirmation control S11 in the opening operation response control S1 and the second opening confirmation control S281 in the (2-8) second restart control S28 in the closing operation response control S2 are repeatedly performed.

[0083] Here, at timing T11, when the opening / closing unit 22 opens, the first detection unit 43 detects the opening operation and transmits a detection signal to the control unit 42. Upon receiving the detection signal from the first detection unit 43, the control unit 42 performs (1-2) first detection stop control S12 and (1-3) second detection start control S13 in the opening operation corresponding control S1, and the second detection restart control S282 of (2-8) second restart control S28 in the closing operation corresponding control S2, at timing T12. In this embodiment, (1-3) second detection start control S13 and (2-8) second detection restart control S282 of second restart control S28 are the same control.

[0084] (1-2) When the first detection stop control S12 is performed, the power supply from the first power supply unit 51 to the first detection unit 43 is cut off, and the transmission of detection signals from the first detection unit 43 stops. Also, when the second detection restart control S282 of the second detection start control S13 and the second restart control S28 of the second restart control S28 are performed, power is supplied from the second power supply unit 52 to the second detection unit 44, and a detection signal is transmitted from the second detection unit 44 to the control unit 42.

[0085] Subsequently, the control unit 42 performs (1-4) first confirmation control S14, and at timing T13, a predetermined time after timing T12, it executes first signal confirmation control S142 and first power supply confirmation control S143. Furthermore, if the control unit 42 confirms through first signal confirmation control S142 and first power supply confirmation control S143 that the first detection unit 43 does not transmit a detection signal and that the power supply to the first detection unit 43 is cut off, it performs (1-5) extraction control S15.

[0086] Then, at timing T14, after a predetermined time has elapsed from timing T13, (1-7) the withdrawal stop control S17 is performed, and the loading platform 31 is withdrawn to the extended position P2, and the driving of the loading platform drive device 3 is stopped.

[0087] Subsequently, at timing T21, when the opening / closing unit 22 closes, the second detection unit 44 detects the closing operation and stops transmitting the detection signal to the control unit 42. The control unit 42, having stopped receiving the detection signal from the second detection unit 44, performs (2-2) second detection stop control S22 and (2-3) first detection start control S23 in the closing operation response control S2, and the first detection restart control S182 of (1-8) first restart control S18 in the opening operation response control S1, at timing T22. In this embodiment, (2-3) first detection start control S23 and (1-8) first restart control S182 are the same control.

[0088] (2-2) When the second detection stop control S22 is performed, the power supply from the second power supply unit 52 to the second detection unit 44 is cut off. Also, (2-3) when the first detection start control S23 and (1-8) the first restart control S182 of the first restart control S18 are performed, power is supplied from the first power supply unit 51 to the first detection unit 43.

[0089] Subsequently, the control unit 42 performs (2-4) second confirmation control S24, and at timing T23, a predetermined time after timing T22, it executes second signal confirmation control S242 and second power supply confirmation control S243. Furthermore, if the control unit 42 confirms through second signal confirmation control S242 and second power supply confirmation control S243 that the second detection unit 44 does not transmit a detection signal and that the power supply to the second detection unit 44 is cut off, it performs (2-5) storage control S25.

[0090] Then, at timing T24, after a predetermined time has elapsed from timing T23, (2-7) storage stop control S27 is performed, and the drive of the loading platform drive unit 3 is stopped when the loading platform 31 is stored to the storage position P1.

[0091] Next, referring to Figure 10, the case in which (1-9) non-execution control S19 is performed in the opening operation corresponding control S1 will be explained. Even in this case, when the opening / closing unit 22 opens at timing T11, the first detection unit 43 detects the opening operation and transmits a detection signal to the control unit 42. Upon receiving the detection signal from the first detection unit 43, the control unit 42 performs (1-2) first detection stop control S12 and (1-3) second detection start control S13 in the opening operation corresponding control S1, and the second detection restart control S282 of (2-8) second restart control S28 in the closing operation corresponding control S2, at timing T12. Here, if the power supply from the first power supply unit 51 to the first detection unit 43 is not interrupted for any reason, the first power supply unit 51 will continue to supply power to the first detection unit 43 even after timing T12, and the first detection unit 43 will continue to transmit a detection signal.

[0092] Subsequently, the control unit 42 performs (1-4) first confirmation control S14, and at timing T13, a predetermined time after timing T12, it executes first signal confirmation control S142 and first power supply confirmation control S143. In the case shown in Figure 10, in first signal confirmation control S142, the first detection unit 43 transmits a detection signal, so the control unit proceeds to non-execution control S19. Therefore, in non-execution control S19, the control unit 42 does not pull out the loading platform 31 based on the detection result of the first detection unit 43.

[0093] Next, with reference to Figure 11, we will explain the case in which (2-9) non-execution control S29 is performed in the closing operation corresponding control S2. In this case, the pulling out of the loading platform 31 to the extended position P2 based on the detection of the opening operation is performed in the same way as in the case shown in Figure 9.

[0094] Then, at timing T21, when the opening / closing unit 22 closes, the second detection unit 44 detects the closing operation and stops transmitting the detection signal to the control unit 42. The control unit 42, having stopped receiving the detection signal from the second detection unit 44, performs (2-2) second detection stop control S22 and (2-3) first detection start control S23 in the closing operation response control S2, and the first detection restart control S182 of (1-8) first restart control S18 in the opening operation response control S1, at timing T22. If, for any reason, the power supply from the second power supply unit 52 to the second detection unit 44 is not interrupted, the second power supply unit 52 will continue to supply power to the second detection unit 44 even after timing T22. Even if power is continuously supplied to the second detection unit 44, the second detection unit 44 will not transmit a detection signal.

[0095] Subsequently, the control unit 42 performs (2-4) second confirmation control S24, and at timing T23, a predetermined time after timing T22, executes second signal confirmation control S242 and second power supply confirmation control S243. In the case shown in Figure 11, since power is supplied to the second detection unit 44 during the second power supply confirmation control S243, the control unit proceeds to non-execution control S29. Therefore, due to non-execution control S29, the control unit 42 does not retract the loading platform 31 based on the detection result of the second detection unit 44.

[0096] With the loading platform vehicle 1 configured as described above, the detection function is stopped by the detection stop control, so the detection unit 41 does not falsely detect the opening or closing of the opening / closing unit 22. Therefore, the loading platform 31 can be used safely.

[0097] Although an example of an embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0098] For example, although the case where the body section 2 is box-shaped has been described, it is not limited to this configuration. For example, the body section 2 can also be configured as a so-called flatbed, comprising a plate-shaped cargo bed 21 and side panels erected on the outer edge of the cargo bed 21. In such a configuration, the side panels constitute the opening / closing section 22. Furthermore, even when the body section 2 is box-shaped, the opening / closing section 22 is not limited to a door, and other configurations such as a sliding door can also be adopted.

[0099] Furthermore, although the example described shows the case where the opening / closing section 22 is provided at the rear end, the configuration is not limited to this, and it can also be provided on the side. In the case of such a configuration, the loading platform 31 can also be configured to unfold to the side of the vehicle.

[0100] Furthermore, although the example described was the detection of the loading platform 31 moving from the storage position P1 to the extension position P2, or from the extension position P2 to the storage position P1, based on a timer, the configuration is not limited to this. For example, the movement of the loading platform 31 from the storage position P1 to the extension position P2, or from the extension position P2 to the storage position P1, can also be detected by other means, such as a sensor provided at the extension position P2 or the storage position P1.

[0101] Furthermore, although the example described shows that the loading platform 31 is moved to the extended position P2 when the opening / closing section 22 is opened, and moved to the stored position P1 when the opening / closing section 22 is closed, it is also possible to configure the system to perform only one of these actions.

[0102] Furthermore, the configuration can be such that when the opening / closing section 22 is opened, the loading platform 31 is moved from the storage position P1 to the deployed position P3, or when the opening / closing section 22 is closed, the loading platform 31 is moved from the deployed position P3 to the deployed position.

[0103] Furthermore, although the detection unit 41 was described using the example of a case where it comprises a first detection unit 43 and a second detection unit 44, it is not limited to this configuration, and it is also possible to have a configuration that comprises only the first detection unit 43. In such a configuration, for example, it is possible to determine that the opening / closing unit 22 has been closed due to the movement of the vehicle or the storage of the loading platform 31, and to perform the first detection start control S23.

[0104] Furthermore, while the first detection stop control S12 and the second detection stop control S22 were described using the example of cutting off the power supply from the power supply unit 5 to the first detection unit 43 and the second detection unit 44, the configuration is not limited to this. For example, it is also possible to configure the system to stop only the signal transmission function, or to configure the system to stop only the operation of the first sensor unit 431 and the second sensor unit 441.

[0105] Furthermore, although the explanation described an example where the withdrawal control S15 is performed after the completion of the first detection stop control S12, and the storage control S25 is performed after the completion of the second detection stop control S22, the system is not limited to this configuration. For example, the first detection stop control S12 can be performed after the withdrawal control S15 and before the withdrawal stop control S17, and the second detection stop control S22 can be performed after the storage control S25 and before the storage stop control S27. Even with such a configuration, it is possible to suppress the movement of the loading platform 31 due to false detection.

[0106] Furthermore, although the first confirmation control S14 has been described as including the first timer control S141, the first signal confirmation control S142, and the first power supply confirmation control S143, the configuration is not limited to this. For example, a configuration that does not include the first timer control S141 is also possible. In such a configuration, for example, the first signal confirmation control S142 and the first power supply confirmation control S143 can be executed immediately after the first detection stop control S12, and the system can proceed to the draw-out control S15 when the transmission of the detection signal stops and the power supply of the first detection unit 43 is OFF. Alternatively, a configuration that does not include the first signal confirmation control S142 is also possible. In such a configuration, the system can proceed to the draw-out control S15 when the power supply of the first detection unit 43 is OFF. Even with such a configuration, since the system proceeds to the draw-out control S15 when the power supply of the first detection unit 43 is OFF and no detection signal is transmitted from the first detection unit 43, the first detection unit 43 will not erroneously detect the opening or closing of the opening / closing unit 22.

[0107] Furthermore, although the second confirmation control S24 has been described as including the second timer control S241, the second signal confirmation control S242, and the second power supply confirmation control S243, the configuration is not limited to this. For example, a configuration that does not include the second timer control S241 is also possible. In such a configuration, for example, the second signal confirmation control S242 and the second power supply confirmation control S243 can be executed immediately after the second detection stop control S22, and if the transmission of the detection signal stops and the power supply of the second detection unit 44 is OFF, the system can proceed to the storage control S25. Alternatively, a configuration that does not include the second signal confirmation control S242 is also possible. In such a configuration, the system can proceed to the storage control S25 if the power supply of the second detection unit 44 is OFF. Even with such a configuration, since the system proceeds to the storage control S25 when the power supply of the second detection unit 44 is OFF and no detection signal is transmitted from the second detection unit 44, the second detection unit 44 will not erroneously detect the opening or closing of the opening / closing unit 22.
