Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, usually, a wing body vehicle is provided with a side awning that can be opened and closed laterally below the wing door. In order to prevent fluttering or unintentional opening due to wind pressure during running, lock mechanisms are provided for the wing door and the side awning, respectively.

[0005] However, unlocking and locking of these lock mechanisms are performed manually, and in many cases, a large force is required for unlocking and locking. Therefore, a great deal of labor has been required for unlocking and locking the lock mechanisms. In particular, in the case of a large wing body vehicle, the lock mechanisms of the wing door and the side awning are often provided at a plurality of locations respectively, so it has been necessary for the user to move to the installation positions of each lock mechanism to perform unlocking and locking.

[0006] Furthermore, there was a problem with accidentally unlocking or closing these locking mechanisms instead of the other. For example, if the locking mechanism for the side panel was accidentally unlocked when the intention was to unlock the wing door to open it, the wing door's locking mechanism would remain locked. This could lead to problems such as the wing door's locking mechanism being damaged or the wing door's drive mechanism being damaged when the wing door is opened.

[0007] Therefore, the present invention aims to provide a cargo compartment opening / closing control system for a wing-body vehicle that enables safe and easy opening and closing of the wing doors and side panels. [Means for solving the problem]

[0008] The present invention provides a cargo compartment opening and closing control system for a wing body vehicle having wing doors and side panels, comprising: a lockable wing lock unit for fixing the wing doors in a predetermined closed position; a lockable side panel lock unit for fixing the side panels in a predetermined closed position; an operating unit for allowing the user to instruct the opening and closing of the wing doors; and a control unit for controlling the wing doors to open or close based on the instruction to open or close the wing doors, wherein the user can also instruct the user to unlock or lock the wing lock unit and the side panel lock unit from the operating unit, and the control unit controls the wing lock unit or the side panel lock unit to unlock or lock based on the instruction to unlock or lock the wing lock unit or the side panel lock unit.

[0009] With this configuration, not only can the wing doors be opened and closed, but the wing lock and tailgate lock can also be controlled from the operating unit. This eliminates the need for the user to move to the installation location of the wing lock and tailgate lock to unlock and lock them. [Effects of the Invention]

[0010] According to the cargo compartment opening / closing control system for a wing-body vehicle of the present invention, the wing doors and side panels can be opened and closed safely and easily. [Brief explanation of the drawing]

[0011] [Figure 1] Explanatory diagram of a wing body vehicle according to an embodiment of the present invention [Figure 2] Block diagram of a cargo compartment opening / closing control system according to an embodiment of the present invention. [Figure 3] Flowchart for unlocking and locking the tailgate lock according to an embodiment of the present invention [Modes for carrying out the invention]

[0012] The following describes the cargo compartment opening / closing control system 1 according to an embodiment of the present invention with reference to Figures 1-3.

[0013] The cargo compartment opening / closing control system 1 is for controlling the opening and closing of the cargo compartment (a pair of wing doors 21 and a pair of side panels 22) of the wing body vehicle 2.

[0014] First, using Figure 1, we will explain the basic structure related to the opening and closing of the wing door 21 and the side panel 22.

[0015] The wing body vehicle 2 includes a pair of wing doors 21, a pair of side panels 22, a floor 23, a pair of gate-type frames 24, a center frame 25, a wing drive unit 26, and a wing opening / closing confirmation unit 27.

[0016] A pair of gate-shaped frames 24 are erected from the front and rear ends of the floor surface 23. In addition, left and right side panels 22 are attached to the left and right ends of the floor surface 23 via hinges so that they can be opened and closed.

[0017] The center frame 25 connects the middle of the upper sides of a pair of portal frames 24, and the left and right wing doors 21 are attached to the center frame 25 via hinges so as to be openable and closable.

[0018] The wing drive unit 26 is for opening and closing the wing door 21. For example, an electric cylinder, a hydraulic cylinder, etc. can be considered. When an electric cylinder or the like is used as the wing drive unit 26, a configuration in which the upper part of the front portal frame 24 and the front side of the wing door 21 are connected by a front electric cylinder, and the upper part of the rear portal frame 24 and the rear side of the wing door 21 are connected by a rear electric cylinder or the like can be considered.

[0019] The wing opening / closing confirmation unit 27 is for confirming that the wing door 21 has been opened to a predetermined open position or closed to a predetermined closed position. For example, when an electric cylinder or the like is used as the wing drive unit 26, a configuration in which a stop signal is transmitted when the electric cylinder extends to the open position of the wing door 21 or contracts to the closed position can be considered.

[0020] Next, the configuration of the cargo compartment opening / closing control system 1 will be described.

[0021] The cargo compartment opening / closing control system 1 is provided inside the wing body vehicle 2. As shown in FIGS. 1 and 2, it includes a wing lock unit 11, a wing lock drive unit 12, an aori lock unit 13, an aori lock drive unit 14, an operation unit 15, and a control unit 16.

[0022] The wing lock unit 11 can lock the wing door 21 to a predetermined closed position. As the wing lock unit 11, for example, a hook or the like that connects between the wing door 2 and the portal frame 24 can be considered. Also, as the type of the wing lock unit 11, a known separable type or integral type can be considered.

[0023] The wing lock drive unit 12 is for unlocking and locking the wing lock unit 11, and for example, a small motor or the like can be considered. When a hook is used as the wing lock unit 11 and a small motor is used as the wing lock drive unit 12, a configuration in which the hook is rotated by driving the small motor to perform unlocking and locking can be considered.

[0024] The aori lock unit 13 can be locked to fix the side aori 22 at a predetermined closed position. As the aori lock unit 13, for example, a hook or the like connecting between the side aori 22 and the portal frame 24 can be considered. Also, as the type of the aori lock unit 13, a known separable type or integral type can be considered.

[0025] The aori lock drive unit 14 is for unlocking and locking the aori lock unit 13, and for example, a small motor or the like can be considered. When a hook is used as the aori lock unit 13 and a small motor is used as the aori lock drive unit 14, a configuration in which the hook is rotated by driving the small motor to perform unlocking and locking can be considered.

[0026] In addition, in this embodiment, it is assumed that the user manually opens and closes the side aori 22 itself.

[0027] The operation unit 15 is for the user to give instructions for opening and closing the wing door 21. In this embodiment, as shown in FIG. 1, it is assumed that the operation unit 15 is provided on the rear side surface of the wing body vehicle 2.

[0028] Furthermore, in the operation unit 15 of this embodiment, the user can also give instructions for unlocking and locking the wing lock unit 11 and unlocking and locking the aori lock unit 13.

[0029] In this embodiment, the operation unit 15 is provided with operation units (buttons, etc.) corresponding to the above-mentioned multiple instructions. Specifically, the operation unit 15 is provided with a first operation unit for instructing the opening of the wing door 21, a second operation unit for instructing the closing of the wing door 21, a third operation unit for instructing the unlocking of the wing lock unit 11, a fourth operation unit for instructing the locking of the wing lock unit 11, a fifth operation unit for instructing the unlocking of the tailgate lock unit 13, a sixth operation unit for instructing the locking of the tailgate lock unit 13, a seventh operation unit for simultaneously instructing the unlocking of the wing lock unit 11, the unlocking of the tailgate lock unit 13, and the opening of the wing door 21, and an eighth operation unit for simultaneously instructing the closing of the wing door 21, the locking of the wing lock unit 11, and the locking of the tailgate lock unit 13. When any of these operation units is operated, a corresponding signal is transmitted.

[0030] Furthermore, since the user may want to stop the opening and closing of the wing door 21 at a position of their choice, in this embodiment, the wing drive unit 26 is driven only while the first and second operating units are being operated by the user (for example, only while the button is pressed).

[0031] The control unit 16 controls the wing door 21 to open or close based on the opening and closing instructions for the wing door 21 transmitted from the operation unit 15. Specifically, it drives the wing drive unit 26 to open or close the wing door 21. When opening or closing the wing door 21, the drive of the wing drive unit 26 is stopped when the operation of the first or second operation unit is stopped, or when a stop signal is transmitted from the wing opening / closing confirmation unit 27.

[0032] Furthermore, in this embodiment, the control unit 16 controls the wing lock unit 11 or the tailgate lock unit 13 to unlock or lock based on the unlocking / locking instruction for the wing lock unit 11 or the tailgate lock unit 13 transmitted from the operation unit 15. Specifically, it drives the wing lock drive unit 12 or the tailgate lock drive unit 14 to unlock or lock the wing lock unit 11 or the tailgate lock unit 13.

[0033] In other words, in this embodiment, not only can the wing door 21 be opened and closed, but the unlocking and locking of the wing lock section 11 and the tailgate lock section 13 can also be controlled by operating the operation unit 15.

[0034] Traditionally, unlocking and locking the wing locks and tailgate locks was done manually, and often required considerable force. Therefore, unlocking and locking the wing locks and tailgate locks required significant effort. In particular, in the case of large wing-body vehicles, the wing locks and tailgate locks are often located in multiple places, requiring the user to move to each location to unlock and lock them.

[0035] However, in this embodiment, the control unit 16 controls the wing lock unit 11 or the tailgate lock unit 13 to unlock or lock based on the unlocking / locking instruction for the wing lock unit 11 or the tailgate lock unit 13 transmitted from the operation unit 15.

[0036] This allows the operating unit 15 to control not only the opening and closing of the wing doors 21 and side panels 22, but also the unlocking and locking of the wing lock section 11 and side panel lock section 13. This eliminates the need for the user to move to the installation location of the wing lock section 11 and side panel lock section 13 to unlock and lock them.

[0037] However, caution is required when opening the side tailgate 22, which is located near the user's height and opens to the side. If the tailgate lock 13 is unlocked due to incorrect operation of the control unit 15, the side tailgate 22 may open unintentionally and collide with the user, potentially causing injury.

[0038] Furthermore, for example, if the wing lock section 11 is supposed to be unlocked in order to open the wing door 21, but the tailgate lock section 13 is accidentally unlocked instead, the wing lock section 11 will remain locked. As a result, when the wing door 21 is opened, the wing lock section 11 may be destroyed or the wing drive section 26 may be damaged.

[0039] On the other hand, since the doors are normally opened in the order of wing door 21 → side panel 22, if the user is instructed to open them in that order, there is a high probability that the user is intentionally trying to open the side panel 22, and the risk of the user colliding with the opened side panel 22 is low.

[0040] Therefore, in this embodiment, the configuration is used in which the unlocking or locking of the wing lock section 11 and the tailgate lock section 13 is controlled by the control unit 16. As shown in Figure 3, the control unit 16 controls the tailgate lock section 13 so as not to unlock it when the wing door 21 has not been confirmed by the wing opening / closing confirmation unit 27 to have been opened to a predetermined open position.

[0041] As a result, when the wing door 21 is not open, even if the operation unit 15 is misoperated and the user is instructed to unlock the tailgate lock unit 13, the tailgate lock unit 13 will not unlock. This significantly reduces the risk associated with the unintended opening of the side tailgate 22, which is located near the user's height and opens to the side. Furthermore, even if the user intends to unlock the wing lock unit 11 to open the wing door 21 but mistakenly operates to unlock the tailgate lock unit 13, the operation will not be effective. This allows the user to realize that they have mistakenly operated to unlock the tailgate lock unit 13, preventing damage to the wing lock unit 11 or the wing drive unit 26 when the wing door 21 is opened.

[0042] Furthermore, when the control unit 15 instructs the user to unlock the wing lock unit 11, unlock the tailgate lock unit 13, and open the wing door 21 all at once, the control unit 16 controls the wing door 21, the wing lock unit 11, and the tailgate lock unit 13 in the order of unlocking the wing lock unit 11, opening the wing door 21, and unlocking the tailgate lock unit 13. After the tailgate lock unit 13 is unlocked, the user can manually open the side tailgate 22.

[0043] This makes it possible to open the cargo area of ​​the wing body vehicle 2 in a safe order with a single operation. For example, it prevents the user from colliding with the opened side panel 22, as described above.

[0044] Similarly, when the control unit 15 instructs the user to close the wing door 21, lock the wing lock unit 11, and lock the tailgate lock unit 13 all at once, the control unit 16 controls the wing door 21, the wing door 21, and the tailgate lock unit 13 in the order of locking the tailgate lock unit 13, closing the wing door 21, and locking the wing lock unit 11. In this case, the user must manually close the tailgate 22 before locking the tailgate lock unit 13.

[0045] This makes it possible to close the cargo area of ​​the wing body vehicle 2 in a safe order with a single operation. For example, if the wing door 21 is closed first, then the side panel 22, there is a possibility that a person could get caught in the space left open by the side panel 22. However, by closing the side panel 22 first, then the wing door 21, such a danger can be prevented.

[0046] As described above, in the cargo compartment opening / closing control system 1 of the wing body vehicle 2 according to this embodiment, the wing lock unit 11 or tailgate lock unit 13 is controlled to open or lock based on an instruction to unlock or lock the wing lock unit 11 or tailgate lock unit 13 from the operation unit 15.

[0047] With this configuration, the operating unit 15 can control not only the opening and closing of the wing doors 21, but also the unlocking and locking of the wing lock section 11 and the tailgate lock section 13. This eliminates the need for the user to move to the installation location of the wing lock section 11 and the tailgate lock section 13 to unlock and lock them. This is particularly effective for large wing-body vehicles where the wing lock section 11 and the tailgate lock section 13 are installed in multiple locations.

[0048] Furthermore, in the cargo compartment opening / closing control system 1 of the wing body vehicle 2 according to this embodiment, the tailgate lock unit 13 is controlled so as not to unlock the tailgate if the wing door 21 has not been confirmed by the wing opening / closing confirmation unit 27 to have been opened to a predetermined open position.

[0049] With this configuration, even if the operation unit 15 is misoperated and the user is instructed to unlock the tailgate lock unit 13 when the wing door 21 is not open, the tailgate lock unit 13 will not unlock. This significantly reduces the risk associated with the unintended opening of the side tailgate 22, which is located near the user's height and opens to the side. Furthermore, even if the user mistakenly attempts to unlock the tailgate lock unit 13 instead of the wing lock unit 11 in order to open the wing door 21, the operation will not be effective. This allows the user to realize that they have mistakenly attempted to unlock the tailgate lock unit 13, preventing damage to the wing lock unit 11 or the wing drive unit 26 when the wing door 21 is opened.

[0050] Furthermore, in the cargo compartment opening / closing control system 1 of the wing body vehicle 2 according to this embodiment, when the operation unit 15 simultaneously instructs the unlocking of the wing lock unit 11, the unlocking of the tailgate lock unit 13, and the opening of the wing door 21, the system controls the wing door 21, the wing lock unit 11, and the tailgate lock unit 13 so that the unlocking of the wing lock unit 11, the opening of the wing door 21, and the unlocking of the tailgate lock unit 13 occur in that order.

[0051] With this configuration, it becomes possible to open the cargo compartment of the wing body vehicle 2 in a safe order with a single operation.

[0052] Furthermore, in the cargo compartment opening / closing control system 1 of the wing body vehicle 2 according to this embodiment, when the operating unit 15 simultaneously instructs the closing of the wing door 21, the locking of the wing lock unit 11, and the locking of the tailgate lock unit 13, the system controls the wing door 21, the wing lock unit 11, and the tailgate lock unit 13 so that the locking of the tailgate lock unit 13, the closing of the wing door 21, and the locking of the wing lock unit 11 occur in that order.

[0053] With this configuration, it becomes possible to close the cargo compartment of the wing body vehicle 2 in a safe order with a single operation.

[0054] Furthermore, the cargo compartment opening / closing control system for a wing-body vehicle of the present invention is not limited to the embodiments described above, and various modifications and improvements are possible within the scope of the claims.

[0055] For example, in the above embodiment, the side tailgate 22 was opened and closed manually, but for example, a tailgate drive unit for opening and closing the side tailgate 22 may be provided on the wing body vehicle 2, and the side tailgate 22 may be configured to be opened and closed electrically. In this case, the configuration may be such that the opening and closing of the side tailgate 22 can be operated all at once. For example, the operation unit 15 may be provided with a ninth operation unit for simultaneously instructing the unlocking of the tailgate lock unit 13, the opening of the wing door 21, and the opening of the side tailgate 22, and a tenth operation unit for simultaneously instructing the closing of the wing door 21, the closing of the side tailgate 22, the locking of the wing lock unit 11, and the locking of the tailgate lock unit 13.

[0056] Then, when the control unit 15 instructs the operation unit 15 to unlock the wing lock unit 11, unlock the tailgate lock unit 13, open the wing door 21, and open the side tailgate 22 all at once, the control unit 16 controls the wing door 21, side tailgate 22, wing lock unit 11, and tailgate lock unit 13 so that the unlocking of the wing lock unit 11, opening of the wing door 21, unlocking of the tailgate lock unit 13, and opening of the side tailgate 22 occur in that order.

[0057] Similarly, when the control unit 15 instructs the wing door 21 to close, the side panel 22 to close, the wing lock unit 11 to lock, and the tailgate lock unit 13 to lock all at once, the control unit 16 controls the wing door 21, the side panel 22, the wing lock unit 11, and the tailgate lock unit 13 so that the closing of the side panel 22, the locking of the tailgate lock unit 13, the closing of the wing door 21, and the locking of the wing lock unit 11 occur in that order.

[0058] Furthermore, in the above embodiment, the tailgate lock unit 13 was controlled so as not to unlock unless the wing door 21 was confirmed to be open to a predetermined open position by the wing opening / closing confirmation unit 27. However, since users may partially open the wing door 21 to transport parts inside the cargo compartment, this predetermined open position is not limited to the fully open position, but may also be an intermediate open position where the door is opened to a certain extent.

[0059] Furthermore, in the above embodiment, the wing doors 21 and side panels 22 were provided in pairs on both the left and right sides, but they may be provided on only one side.

[0060] Furthermore, although hooks were used as the wing lock portion 11 and the tailgate lock portion 13 in the above embodiment, the invention is not limited to hooks as long as it is possible to unlock and lock the doors.

[0061] Furthermore, in the above embodiment, the wing opening / closing confirmation unit 27 confirmed the opening and closing in accordance with the extension and retraction of the electric cylinder, etc., but it is also possible to determine whether a predetermined open position or predetermined closed position has been reached according to the current value or rotation speed of the wing drive unit 26, or simply to provide sensors at the open position and closed position.
