Description

Technical Field

[0001] The present invention relates to a loading box cover for a vehicle, and more particularly, to a foldable loading box cover assembly having a pop-up guide rail that guides a folding operation of a cover unit. Background Art

[0002] refer to Figure 1 In a vehicle 100 such as a pickup truck, a loading bed, a load box, a loading box, etc., ie, a loading box 110 having a predetermined size, is provided at a rear end of the vehicle 100 .

[0003] The loading box 110 is provided with a cover to protect the cargo loaded in the loading box 110. In one example, the cover is provided in the form of a roller shutter 130 to reduce the volume when stored. When the roller shutter 130 is deployed or released, the upper part of the loading box 110 can be closed to prevent foreign matter such as dust from entering the cargo loaded in the loading box 110, or to prevent the cargo from being separated or ejected from the loading box 110.

[0004] The rolling curtain 130 is rolled up and accommodated in a housing 140 installed in the loading box 110, so that the rolling curtain 130 can be stored by being rolled up (see FIG. Figure 2 Part A) of the embodiment of the present invention has a problem that the internal space of the loading box 110 is reduced due to the space occupied by the housing 140, thereby reducing the available cargo loading space.

[0005] In addition, since the height h between the lower surface of the loading box 110 and the lower end of the housing 140 becomes smaller than the portion where the housing 140 is not installed, there is a problem that the utilization rate of the middle door 120 provided between the passenger compartment of the vehicle and the loading box 110 is reduced. In other words, by opening the middle door 120, a part of the long cargo can be stored in the second row seat area of ​​the passenger compartment. Since the housing 140 protrudes downward, there is a problem that the housing 140 intrudes into a part of the loading space even when the middle door is opened, thereby limiting the use of the loading space. Summary of the invention

[0006] The present invention is proposed to solve the above problems. The present invention is intended to provide a foldable loading box cover assembly for a vehicle and having a pop-up guide rail. The assembly has a portion of a guide rail for supporting and guiding the side of a slat used to cover the upper or top opening of the loading box of the vehicle. The guide rail pops up or overlaps the loading box in conjunction with the operation of the slat.

[0007] To achieve these and other objects, there is provided a collapsible loading box cover assembly for a vehicle having a pop-up guide rail. The cover assembly may include a cover unit including a plurality of slats and collapsible to cover an upper portion of a loading box of the vehicle. The cover assembly further includes a guide rail unit mounted or disposed on the upper portion of the loading box in an unfolding direction of the cover unit. The guide rail unit is configured to be pop-upable to guide sliding of upper and lower ends of the plurality of slats.

[0008] Each of the plurality of slats is alternately connected to another adjacent slat for folding, and the slat folds toward or unfolds from the loading box of the vehicle. The guide rail unit includes a lower guide rail mounted or disposed at an upper end of the loading box of the vehicle in an unfolding direction of the cover unit and configured to guide a lower end of the slat. The guide rail unit further includes an upper guide rail mounted or disposed above the lower guide rail parallel to the lower guide rail and configured to guide an upper end of the slat.

[0009] The assembly further includes a plurality of connecting members connecting the lower guide rail to the upper guide rail. When the cover unit is folded, the upper guide rail is popped out, i.e., flown out, from the lower guide rail to guide sliding of the upper end of the slat.

[0010] The plurality of connecting members may be provided at intervals in a longitudinal direction of the vehicle.

[0011] At least any one of the plurality of connecting members may be connected to a sub-connecting member.

[0012] The sub-connecting member may be connected to a connecting rod mounted or disposed along the lower guide rail. When the cover unit is unfolded, the slat may pull the connecting rod to support the sub-connecting member at a rear portion of the vehicle.

[0013] The sub-connecting member may be connected to one of the plurality of connecting members adjacent to a rear end of the vehicle.

[0014] When the cover unit is unfolded, the distal or outermost slat positioned closest to the rear end of the vehicle may support the connecting rod at the rear portion of the vehicle.

[0015] The connecting rod may be supported at the rear portion of the vehicle through a bracket connected to the distal or outermost slat positioned closest to the rear end of the vehicle.

[0016] The connecting rod may be connected to the bracket and supported at the rear portion of the vehicle by a cable configured to fold or unfold the plurality of slats.

[0017] The connecting rod may be elastically supported at a front portion of the vehicle by a spring.

[0018] A bracket connecting two adjacent slats of the plurality of slats may be provided. A slider in the form of a roller may be mounted or disposed on the bracket and configured to slide on the lower guide rail or the upper guide rail.

[0019] When the cover unit is folded, the slide mounted on the bracket connecting the upper ends of two adjacent slats can slide along the lower surface of the upper guide rail, and the slide mounted on the bracket connecting the lower ends of two adjacent slats can slide along the upper surface of the lower guide rail.

[0020] A proximal or nearest slat among the plurality of slats that is positioned closest to the front end of the vehicle may be rotatably mounted to the lower rail.

[0021] The foldable loading compartment cover assembly for a vehicle having a pop-up rail may further include a connector disposed between two adjacent slats, and each of the two adjacent slats may be hinged via the connector.

[0022] The sealing strip may be disposed between the slats and the connector and configured to seal between two adjacent slats or between each slat and the connector.

[0023] The foldable loading box cover assembly for a vehicle with a pop-up guide may further include: a drive motor; a drive gear configured to be rotated by the drive motor; and a cable engaged with the drive gear through a spiral on its outer circumference or through teeth provided in the longitudinal direction of the cable. The cable may be configured to push or pull the end of the cover unit according to the rotation of the drive gear. The far or farthest side slat of the cover unit, which is positioned to be most spaced apart from the drive motor, is pushed to unfold the cover unit or pulled to fold the cover unit.

[0024] A pair of cables may be provided and connected respectively to both ends of a remote or farthest slat of the cover unit, which slat is located maximally spaced from the drive motor.

[0025] The foldable loading box cover assembly for a vehicle with a pop-up guide rail may further include a housing in which a drive motor and a drive gear are installed. The housing may be fixed to a front end of the lower guide rail, and a cable groove in which a cable is installed may be formed in the housing.

[0026] A vehicle having a cargo box may include a foldable cargo box lid assembly having pop-up rails according to the above description.

[0027] According to the foldable loading box cover assembly for a vehicle with a pop-up guide rail of the present invention, when the upper portion of the loading box is opened, in conjunction with the folding of the slats of the cover unit, the upper guide rail may pop out from the lower guide rail to form an operating path for the slats.

[0028] Furthermore, since the upper portion of the loading box is generally flat when the slats close the upper portion of the loading box, the portion protruding to the upper portion of the loading box may disappear when the loading box is closed, making the appearance of the vehicle more beautiful.

[0029] In addition, since the slats covering the loading box are folded to the upper part of the loading box, the internal space of the loading box will not be reduced. Description of the Drawings

[0051] Hereinafter, a collapsible loading hatch cover assembly for a vehicle having a pop-up guide rail according to the present invention will be described in detail with reference to the accompanying drawings. When a component, device, element, etc. of the present invention is described as having a purpose or performing an operation, function, etc., the component, device, or element should be regarded as "configured to" meet the purpose or perform the operation or function herein. As used herein for a loading hatch, upper and lower may refer to portions of the lid when in a folded state. When the lid is in an unfolded or in-use state, these portions may be substantially in the same plane and may not, therefore, be regarded as upper and lower in the unfolded or in-use state.

[0052] The collapsible loading hatch cover assembly for a vehicle having a pop-up guide rail according to the present invention may include a lid unit 30. The lid unit 30 includes a plurality of slats 31, where each slat 31 has upper and lower ends alternately connected to another adjacent slat 31. The lid unit 30 folds towards or unfolds from the loading box 10 of the vehicle 1. The cover assembly may further include a guide rail unit 20, which is mounted on the upper part of the loading box 10 in the unfolding direction of the lid unit 30. The guide rail unit 20 is configured to pop out, i.e., jump out, for guiding the sliding of the upper and lower ends of each of the plurality of slats 31.

[0053] The guide rail unit 20 may include a lower guide rail 21, which is mounted on the upper end of the loading box 10 in the unfolding direction of the lid unit 30. The lower guide rail 21 may be configured to guide the lower end of each of the slats 31. An upper guide rail 22 may be mounted above the lower guide rail 21 parallel to the lower guide rail 21 and configured to guide the upper end of each of the slats 31.

[0054] The guide rail unit 20 further includes a plurality of connecting links 23 connecting the lower guide rail 21 and the upper guide rail 22. When the lid unit 30 is folded, i.e., in a folded state or being folded, the upper guide rail 22 pops out from the lower guide rail 21 to guide the sliding of the upper ends of the slats 31.

[0055] The lid unit 30 may include a plurality of slats 31. The slats 31 have upper and lower ends alternately connected to other adjacent slats 31 and may fold towards or unfold from the loading box 10 of the vehicle 1.

[0056] The slats 31 may be connected in one direction of the vehicle 1, for example, in the longitudinal or length direction of the vehicle 1. The slats 31 may be unfolded or folded in the longitudinal direction of the vehicle 1. When the slats 31 are unfolded, the upper part of the loading box 10 may be closed by the unfolded slats 31 of the lid unit 30. When the slats 31 are folded, the area of the upper part of the loading box 10 except for some sections may be opened.

[0057] The slats 31 may be formed to extend longer in the width direction of the vehicle 1 than in the longitudinal direction of the vehicle 1.

[0058] As described above, the front or edge and the rear or edge of the slat 31 in the longitudinal direction of the vehicle 1 can be connected to each other and folded together in the longitudinal direction of the vehicle 1.

[0059] In the slat 31, the slat 31 disposed closest to the front end of the vehicle 1, that is, the closest or nearest-side slat, can be rotatably connected to the lower guide rail 21, details of which are described below.

[0060] Connectors 32 can be provided such that each connector connects two adjacent slats 31 on each side of the vehicle. The connector 32 can be disposed between two adjacent slats 31. The rotating shaft (see 37 in Fig. 20 ) penetrates through the slat 31 and the connector 32 such that the slat 31 can be folded. For example, both side ends of each slat 31 can be bent, and the rotating shaft can pass through the bent portion and the connector 32 at each side end to connect the adjacent slats 31 to the connector 32.

[0061] The connector 32 can connect two adjacent slats 31 at intervals, and the connecting portion of the slats can be rotated to allow the cover unit 30 to be folded or unfolded.

[0062] Each slat 31 can have an extension portion 31a formed toward another slat 31 adjacent to its end. When the cover unit 30 is unfolded and the slats 31 are arranged along a plane, the extension portion 31a can cover the space between the slat 31 and the connector 32.

[0063] Brackets 33 can be installed to guide the movement of the cover unit 30 and reduce friction when the cover unit 30 is folded or unfolded. Sliding members 33a in the form of rollers can be provided on each bracket 33. When the cover unit 30 is folded, the brackets 33 can be installed to connect the upper and lower ends of two adjacent slats 31, and the sliding members 33a can be rotatably installed on the brackets 33. The sliding members 33a can be provided in the form of rollers and can perform rolling contact during sliding to reduce friction. When the cover unit 30 is folded, the sliding members 33a slide alternately along the upper guide rail 22 and the lower guide rail 21, which is described below.

[0064] Through holes 33b can be formed in each bracket 33. The rotating shaft 37 can be installed to penetrate through the through hole 33b, the corresponding slat 31, and the connector 32.

[0065] Weather strips 35 and 36 can be provided to seal between two adjacent slats 31 and between the slat 31 and the connector 32 (see Fig. 20 ).

[0066] The sealing strips 35 and 36 can be slat sealing strips 35, which seal between the slat 31 and the connector 32 when the slat 31 is deployed. The slat sealing strip 35 can be installed at the end of the slat 31 and is arranged in a form surrounding the connector 32. When the slat 31 is deployed or folded, the slat sealing strip 35 can surround the connector 32 and seal between the slat 31 and the connector 32.

[0067] Alternatively, the sealing strips 35 and 36 can be connector sealing strips 36 fastened to the connector 32 to seal between two adjacent slats 31 when the slat 31 is deployed. The connector sealing strip 36 can be fastened to the connector and is deformed by being compressed between the ends of the slat 31 when the slat 31 is deployed, while sealing between the slats 31.

[0068] Since the sealing is carried out between two adjacent slats 31 and between the slat 31 and the connector 32 by the sealing strips 35 and 36, moisture or foreign substances can be prevented from flowing into the loading box 10, thereby preventing the loading box 10 and any goods loaded in the loading box 10 from being contaminated.

[0069] The lower guide rail 21 can be installed at the upper end of the loading box 10. The lower guide rail 21 can be installed at the upper end of the loading box 10 in the longitudinal direction of the vehicle 1. The lower guide rail 21 can have an open upper part to allow the slider 33a to slide along the upper surface of the lower guide rail 21. Thus, when the cover unit 30 is folded, the lower guide rail 21 guides the lower end of the slat 31.

[0070] The closest or nearest side slat 31 positioned at the front end of the lower guide rail 21, that is, the slat 31 closest to the front end of the vehicle 1 among the slats 31, can be rotatably connected to the lower guide rail 21. The slat 31 rotatably connected to the lower guide rail 21 can only rotate individually and does not slide when the cover unit 30 is folded or deployed.

[0071] The cable slot 21a for accommodating the cable 45 can be formed in the lower guide rail 21. The cable slot 21a can be formed in the same direction as the direction of the lower guide rail 21 and can become a channel for the cable 45 to move when the cover unit 30 is deployed or folded.

[0072] The upper guide rail 22 can be installed above the lower guide rail 21 parallel to the lower guide rail 21. The upper guide rail 22 can have an open lower surface, and the slider 33a slides along the lower surface of the upper guide rail 22. Therefore, when the cover unit 30 is folded, the upper guide rail 22 can guide the upper end of the slat 31. Therefore, when the cover unit 30 is folded, the upper guide rail 22 can guide the upper end of the slat 31.

[0073] When the cover unit 30 is folded, when the slat 31 is inclined relative to the lower guide rail 21 and one end of the slat 31 moves upward, the upper guide rail 22 can pop up by separating from the lower guide rail 21 to guide the sliding of the upper end of the slat 31.

[0074] The connecting member 23 can connect the upper guide rail 22 to the lower guide rail 21. The upper end of the connecting member 23 can be hinged to the upper guide rail 22, and its lower end can be hinged to the lower guide rail 21. A plurality of connecting members 23 can be arranged at intervals in the longitudinal direction of the vehicle 1 so that the lower guide rail 21, the upper guide rail 22, and the connecting member 23 can have a four-joint link structure.

[0075] The upper guide rail 22 can overlap with the lower guide rail 21 through the connecting member 23, or can pop up from the lower guide rail 21.

[0076] In order to maintain the state where the upper guide rail 22 overlaps with the lower guide rail 21 in the state where the cover unit 30 is fully unfolded, a sub-connecting member 24 and a connecting bar 25 can be provided.

[0077] The sub-connecting member 24 and the connecting bar 25 can support at least one of the plurality of connecting members 23 to the rear of the vehicle 1 so that when the cover unit 30 is unfolded, the upper guide rail 22 is fixed in a state of overlapping with the lower guide rail 21.

[0078] In addition, when the cover unit 30 is folded, the sub-connecting member 24 and the connecting bar 25 can move in front of the upper guide rail 22 so that the upper guide rail 22 can pop up from the lower guide rail 21.

[0079] The upper end of the sub-connecting member 24 can be connected to the middle of the connecting member 23. When the lower end of the sub-connecting member 24 is pulled toward the rear of the vehicle 1, the sub-connecting member 24 pulls the connecting member 23 to fix the upper guide rail 22 in a state of overlapping with the lower guide rail 21.

[0080] The connecting bar 25 can be installed on the lower guide rail 21 in the longitudinal direction of the lower guide rail 21. One end of the connecting bar 25 can be connected to the lower end of the sub-connecting member 24 so that the connecting bar 25 pulls the sub-connecting member 24 or the sub-connecting member 24 pulls the connecting bar 25.

[0081] The sub-connecting member 24 and the connecting bar 25 can be connected in such a way that they are fixed by pulling the connecting member 23 located at the rearmost side. In other words, the sub-connecting member 24 can be connected to the connecting member 23 among the plurality of connecting members 23 that is adjacent to the rear end of the vehicle 1.

[0082] When the cover unit 30 is deployed, the distal or farthest side slat 31 positioned closest to the rear end of the vehicle 1 can support the connecting rod 25 toward the rear of the vehicle 1. Accordingly, the connecting rod 25 can pull the sub-connector 24 toward the rear of the vehicle, and the sub-connector 24 can pull the connector 23 toward the rear of the vehicle 1, such that the upper guide rail 22 overlaps with the lower guide rail 21. Accordingly, the upper guide rail 22 can be fixed to the lower guide rail 21.

[0083] The connecting rod 25 can be supported toward the rear of the vehicle 1 by a carrier 34 connected to the distal or farthest side slat 31 positioned closest to the rear end of the vehicle 1 or by a cable 45 connected to the carrier 34. In other words, when the cover unit 30 is deployed, the slat 31 positioned on the rearmost side can pull the connecting rod 25 toward the rear of the vehicle 1 while moving toward the rear of the vehicle 1.

[0084] In addition, the rear end of the connecting rod 25 can be elastically supported toward the front of the vehicle 1 by a spring 26. When the cover unit 30 starts to be deployed, the spring 26 can push the connecting rod 25 toward the front of the vehicle 1.

[0085] The loading box 10 can be provided with a drive motor 43 for folding or deploying the cover unit 30 and a cable 45 for transmitting the driving force of the drive motor 43.

[0086] A housing 41 for mounting the drive motor 43, for example, at the front end of the loading box 10 on one side of the loading box 10 and a cover 42 for covering the housing 41 can be installed, and the drive motor 43 can be installed in the housing 41. When power is applied, the drive motor 43 can operate to allow the cover unit 30 to be deployed or folded. A cable groove 41a can be formed in the housing 41, and the cable 45 is received in the cable groove.

[0087] A drive gear 44 can be fixed to the drive motor 43, and the drive gear 44 can be rotated by the drive motor 43. The drive gear 44 can transmit the driving force of the drive motor 43 to the cable 45. The drive gear 44 can be a spur gear having teeth formed around it.

[0088] The cable 45 can be formed to engage with the drive gear 44. A helix can be formed on the outer circumferential surface of the cable 45, or teeth can be formed on the cable 45 longitudinally to mesh with the drive gear 44. The cable 45 can have flexibility to be bent along the shape of the cable groove 41a or the cable groove slit 21a and can have an appropriate stiffness such that the cable 45 can push the carrier 34 connected to the other end of the cable 45.

[0089] Although the cable 45 is shown as being double-mounted between the housing 41 and the cover 42, the two cables 45 can each be connected to the drive gear 44 and the slat 31 of the cover unit 30 positioned at the rearmost end of the vehicle. Figure 7The other end of the cable 45 is shown connected to the bracket 34 of the slat 31. The bracket 34 can be fixed to the slat 31, and the other end of the cable 45 can be fixed to the bracket 34. One side of the cable 45 can engage with the drive gear 44, and the other end of the cable 45 can be connected to the rearmost remote or farthest side slat 31 mounted through the cable slot 21a. Two cables 45 can engage with the drive gear 44, and depending on the rotation direction of the drive gear 44, the cable 45 can be pulled towards the drive gear 44 or moved in the opposite direction.

[0090] The operation of the collapsible loading box cover assembly for a vehicle with a pop-up guide rail according to the present invention having the above configuration is described below.

[0091] Fig.10 and Fig.11 The state in which the cover unit 30 is folded is shown. In other words, the slats 31 can be alternately arranged to be folded in an upright state, and the upper guide rail 22 can be in a state of popping out from the lower guide rail 21. In this state, the upper guide rail 22 can be in a state of being spaced apart from the loading box 10, the slats 31 can be arranged almost perpendicular to the ground (i.e., in a substantially vertical orientation), and the connecting member 23 can be in a state of being maximally inclined with respect to the lower guide rail 21.

[0092] In this state, since the rest of the upper part of the loading box 10 except for the part where the cover unit 30 is folded is open, goods can be loaded into the loading box 10, or goods can be unloaded from the loading box 10.

[0093] Starting from this state, when the drive motor 43 is operated to close the cover unit 30, the drive motor 43 can rotate the drive gear 44, and one or more cables 45 can start to move towards the rear of the vehicle 1.

[0094] When the cable 45 moves towards the rear of the vehicle 1, the bracket 34 can also start to move towards the rear of the vehicle 1 together with the other end of the cable 45, and the cover unit 30 starts to unfold.

[0095] Fig.12 and Fig.13 The intermediate state between the state in which the cover unit 30 is maximally folded and the state in which the cover unit 30 is fully unfolded is shown.

[0096] When the cable 45 moves towards the rear of the vehicle, when the bracket 34 pulls the slat 31 positioned at the rearmost side of the cover unit 30 and moves the slat 31 towards the rear of the vehicle, the slat 31 can change from a state perpendicular to the ground to an inclined state, and the remaining slats 31 also move in sequence.

[0097] At this time, when the upper end of the slat 31 moves downward, and the upper rail 22 also moves downward, the inclination of the connecting member 23 can also be lowered.

[0098] As described above, when the cover unit 30 is unfolded, the height of the upper end of the slat 31 can be reduced, and in conjunction with this, the upper rail 22 can also become closer to the lower rail 21. In addition, the lower surface of the upper rail 22 and the upper surface of the lower rail 21 can be in an open state, and the slider 33a slides along the lower surface of the upper rail 22 or slides along the upper surface of the lower rail 21.

[0099] When the cover unit 30 is further unfolded, the height of the upper end of the slat 31 decreases, and the upper rail 22 may also become closer to the lower rail 21 .

[0100] In addition, when the inclination angle of the connecting member 23 relative to the lower rail 21 decreases, the lower end of the sub-connecting member 24 can push the connecting rod 25 toward the rear of the vehicle 1 .

[0101] Fig.14 and Fig.15 The state in which the cover unit 30 is fully unfolded is shown.

[0102] When the cable 45 moves maximally toward the rear of the vehicle 1, the slat 31 of the cover unit 30 becomes parallel to the ground, that is, in a substantially horizontal state or in parallel to the upper portion of the loading box 10. In addition, the upper rail 22 may overlap with the lower rail 21, and the slider 33a may be positioned between the upper rail 22 and the lower rail 21.

[0103] Figures 16 to 18 The state of the connecting rod 25 in each state of the cover unit 30 is shown.

[0104] Fig.16 The state in which the cover unit 30 is fully deployed is shown. The bracket 34 connected to the remote or farthest slat 31 located at the rearmost side or the cable 45 connected to the bracket 34 can push the spring seat 26a installed at the rear end of the connecting rod 25 toward the rear of the vehicle 1 to support the connecting rod 25 at the rear of the vehicle 1. Therefore, when the connecting rod 25 pushes the sub-connector 24 toward the rear of the vehicle 1 and the connecting member 23 overlaps the lower rail 21 to the maximum extent, the lower surface of the upper rail 22 can contact the upper surface of the lower rail 21, and this state is maintained.

[0105] Fig.17 The cover unit 30 is shown in a state where it starts to be folded. When the slat 31 starts to move toward the front of the vehicle 1, the spring 26 can push the spring seat 26a to move the connecting rod 25 toward the front of the vehicle 1.

[0106] Subsequently, when the lid unit 30 is folded, as the slats 31 continuously move toward the front of the vehicle 1, the bracket 34 or the cable 45 may become separated from the connecting rod 25 (see Fig.18 ).

[0107] When the lid unit 30 is deployed from the folded state, at the end point of the deployment, as the outermost or the farthest side slat 31 closest to the rear end of the vehicle 1 continuously moves toward the rear of the vehicle 1 with the bracket 34 or the cable 45 approaching the other end of the connecting rod 25 (see Fig.18 ), the bracket 34 or the cable 45 may contact the spring seat 26a and start to move the connecting rod 25 (see Fig.17 ). When the slat 31 moves to the maximum extent, the bracket 34 or the cable 45 moves the connecting rod 25 to the maximum extent to fix the upper guide rail 22 in a state overlapping with the lower guide rail 21.

[0108] Fig.19 A perspective view showing the state where the lid unit 30 is fully deployed is shown.

[0109] As Fig. 20 shown, when the lid unit 30 is fully deployed, the upper part of the loading box 10 is closed. In addition, when the lid unit 30 is fully deployed, the slats and the connector 32 can be sealed by the slat sealing strip 35 and the connector sealing strip 36 mounted on the slats 31 and the connector 32.

[0110] In the state where the lid unit 30 is fully deployed, the upper guide rail 22 covers the upper surface of the lower guide rail 21 (see Fig.21 ). Since the lower surface of the upper guide rail 22 and the upper surface of the lower guide rail 21 can be open, when the upper guide rail 22 can overlap with the lower guide rail 21, the upper guide rail 22 can be changed to a state of being joined to the lower guide rail 21, thereby preventing foreign objects from being introduced therebetween.

[0111] In order to open the loading box 10 by folding the lid unit 30 in the state where the lid unit 30 is deployed and the lid unit 30 closes the loading box 10, the above-described deployment process of the lid unit 30 can be executed in the reverse order.

[0112] That is, when the drive motor 43 rotates in the reverse direction, the cable 45 can pull the rear end of the outermost or the farthest side slat 31 toward the front of the vehicle 1. Thereafter, the slat 31 can be folded and become inclined with respect to the lower guide rail 21, and a part of the bracket 33 can move upward along the upper end of the folded slat 31. At the same time, the upper guide rail 22 can pop out by separating from the lower guide rail 21.

[0113] When the cable 45 further pulls the slat 31, the upper end of the slat 31 can move further upward while tilting from a state parallel to the ground to a state perpendicular to the ground, and the pop-out amount of the upper guide rail 22 can increase.

[0114] Thereafter, when the cable 45 pulls the slat 31 to the maximum extent, the slat 31 can be in a state perpendicular to the ground, and the cover unit 30 can be folded to the maximum extent, so as to open the upper part of the loading box 10. In addition, the upper guide rail 22 can be in a state of being ejected to the maximum extent relative to the lower guide rail 21.
