Description

Technical Field

[0001] The present invention relates to the field of automobile technology, in particular to a cargo box of a pickup truck having a variable track type rolling curtain mechanism. The present invention also relates to a car provided with the cargo box. Background Art

[0002] With the rapid development of pickup truck sales in China and the increasing number of pickup truck users, more and more demands for cargo boxes have been put forward. The traditional pickup truck cargo box has both the convenience of loading and unloading and the comfort of driving and riding.

[0003] Different users have different demands for cargo boxes. For example, traditional cargo boxes can meet the requirements for loading and unloading oil drums, turnover boxes, karts, bicycles, etc., while loading and unloading relatively square flat pallets, larger cartons, wooden boards, wooden frames and other items will be restricted by the cargo box wheel bags (that is, the bulging part inside the cargo box to avoid the wheels), which affects the convenience of loading and unloading. Only flat-bottomed cargo boxes can be used for loading and unloading. Some users will load some suitcases, electrical devices and other items when traveling, and they need flat-top cargo boxes for closed storage to ensure privacy. As of the current status of pickup trucks, they can only meet one storage function and are not compatible with three storage usage scenarios.

[0004] In other words, the current pickup truck users' demands for cargo boxes are divided into three categories. The first category is a large-volume cargo box with wheeled bags, the second category is a flat-bottom cargo box with modular loading and unloading, and the third category is a flat-top cargo box, that is, a closed cargo box with a large travel range. As for the traditional rolling shutter cover, it can only meet one or two storage scenarios and is not compatible with three storage usage scenarios. If the user chooses a large cargo box with wheeled bags, he cannot switch to a flat-bottom cargo box with modular loading and unloading, nor can he switch to a closed flat-top cargo box, which reduces the user experience. Summary of the invention

[0005] The object of the present invention is to provide a cargo box with a variable track type rolling shutter mechanism. The cargo box can be switched to a large storage cargo box with wheels and a flat bottom modular storage cargo box, thereby meeting the needs of different users for loading different goods without reducing the effective volume of the cargo box.

[0006] Another object of the present invention is to provide a pickup truck having a cargo box with the variable track roller shutter mechanism.

[0007] To achieve the above-mentioned objectives, the present invention provides a cargo box with a variable track roller shutter mechanism, comprising a cargo box and a roller shutter mechanism arranged on the front side of the cargo box, wherein slide rails cooperating with the roller shutter cover of the roller shutter mechanism are arranged on both sides of the cargo box to guide the roller shutter cover to be unfolded and retracted, wherein the slide rails comprise an upper slide rail and a lower slide rail, wherein a transition slide rail extending downward is arranged at the front end of the upper slide rail, and an adjustment slide rail is arranged between the lower end of the transition slide rail and the front end of the lower slide rail; in a first state, the adjustment slide rail is connected with the lower slide rail, and the roller shutter cover can be unfolded along the lower slide rail and extended to the rear tailgate of the cargo box to form a flat-bottom cargo box; in a second state, the adjustment slide rail is connected with the upper slide rail, and the roller shutter cover can enter the upper slide rail along the transition slide rail, unfold along the upper slide rail and extend to the rear tailgate of the cargo box to form a closed flat-cover cargo box.

[0008] Optionally, the cargo box is a split cargo box, and the rolling shutter mechanism is arranged on the front side of the cargo box.

[0009] Optionally, the cargo box is an integrated cargo box, and the rolling curtain mechanism is arranged behind the second row of seats in the cockpit and passes through the front side of the cargo box.

[0010] Optionally, the adjustment slide rail is rotatably mounted on the cargo box. In a first state, it is in a horizontal state to guide the rolling shutter cover into the lower slide rail. In a second state, it is in a vertical state after rotating 90° to guide the rolling shutter cover into the transition slide rail.

[0011] Optionally, the rolling shutter cover is provided with a supporting mechanism for supporting it from the bottom upwards after being unfolded.

[0012] Optionally, the supporting mechanism includes a sliding metal plate and a supporting rod; the sliding metal plate can be installed on the rolling shutter cover in a transversely movable manner, and the supporting rod is located under the sliding metal plate; one end of the supporting rod is connected to the rolling shutter cover through a rotating shaft, and the other end of the supporting rod is provided with a magnetic head; one end of the sliding metal plate is provided with an adjusting handle, and the other end is provided with a return pusher and a return spring for driving the support rod to return; in the storage state, the support rod is parallel to the sliding metal plate, and is adsorbed and fixed to the sliding metal plate through the magnetic head, and in the supporting state, the magnetic head of the support rod is separated from the sliding metal plate and rotated to a vertical state, and its lower end is supported on the inner bottom of the cargo box.

[0013] Optionally, the return pusher has a semicircular groove that can be matched with one arc-shaped end of the support rod and a push head for pushing the support rod to rotate in the opposite direction around the rotating shaft.

[0014] Optionally, the magnetic head of the support rod has a plane for supporting the inner bottom of the cargo box, and an arc surface is provided on one side of the plane for avoiding the inner bottom of the cargo box when the support rod rotates downward.

[0015] Optionally, the lower track fits against the upper edge of the wheel bag of the cargo box.

[0016] To achieve the above-mentioned other objective, the present invention provides a pickup truck, comprising a vehicle body and a cargo box arranged on the vehicle body, wherein the cargo box is any of the above-mentioned cargo boxes with a variable track-type rolling shutter mechanism.

[0017] The cargo box with a variable track roller shutter mechanism provided by the present invention is provided with two layers of slide rails, one of which is an upper slide rail and the other is a lower slide rail, and is provided with a transition slide rail for conducting to the upper slide rail and an adjustment slide rail for switching. The position of the roller shutter cover of the roller shutter mechanism can be controlled by adjusting the slide rail, so that the roller shutter cover can be unfolded in the lower layer and extended to the rear baffle of the cargo box to form a flat-bottom cargo box, and the roller shutter cover can also be extended to the upper layer of the cargo box and unfolded to form a closed flat-cover cargo box, thereby forming a large trunk. This double-layer slide rail structure realizes the arbitrary switching of the three storage modes of wheeled cargo box, flat-bottom cargo box, and flat-cover cargo box. At the same time, in the flat-bottom cargo box mode, the lower layer can also be used to expand the storage compartment to realize diversified storage scenarios.

[0018] The pickup truck provided by the present invention is provided with the cargo box with the variable track type rolling shutter mechanism. Since the cargo box with the variable track type rolling shutter mechanism has the above-mentioned technical effects, the pickup truck provided with the cargo box with the variable track type rolling shutter mechanism should also have the same technical effects.

[0028] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0030] like Figure 1 , Figure 7 As shown, in a specific embodiment, the cargo box with a variable track type rolling shutter mechanism provided by the present invention is mainly composed of a cargo box 1 and a rolling shutter mechanism 2 arranged on the front side of the cargo box 1, and the rolling shutter mechanism 2 is composed of components such as a rolling shutter box 21, a rolling shutter shaft 22 and a rolling shutter cover 23. The rolling shutter box 21 is provided with a rolling shutter cover entrance and exit, and the rolling shutter cover 23 is a crawler structure, which is connected by a plurality of rolling shutter plates and has a certain flexibility. It can be extended outward into a plane to carry various articles, and can also be rolled up inside the rolling shutter box 21. One end of the rolling shutter shaft 22 is connected to a motor, and driven by the motor, the rolling shutter cover 2 is extended outward or retracted.

[0031] Slide rails cooperating with the roller shutter cover 23 of the roller shutter mechanism 2 are provided on both sides of the cargo box 1 to guide the roller shutter cover 23 to unfold and retract, and the slide rails are divided into an upper slide rail 3 and a lower slide rail 4, wherein a transition slide rail 5 extending downward is provided at the front end of the upper slide rail 3, and an adjustment slide rail 6 is provided between the lower end of the transition slide rail 5 and the front end of the lower slide rail 4.

[0032] When the roller shutter cover 23 is fully retracted into the roller shutter mechanism 2, the cargo box 1 is in a large-volume wheeled cargo box storage mode. In this state, it can be used to place oil drums, turnover boxes, karts, bicycles or irregularly shaped items.

[0033] like Figure 2 , Figure 3 As shown, the adjustment slide rail 6 is rotatably mounted on the cargo box 1 and can be rotated electrically or manually, and can be selectively connected with the transition slide rail 5 of the lower slide rail 4 or the upper slide rail 3.

[0034] In the first state, the adjusting slide rail 6 is in a horizontal state and connected with the lower slide rail 4 to guide the rolling shutter cover 23 into the lower slide rail 4. The motor of the rolling shutter mechanism 2 is started to push out the tracked rolling shutter cover 23. The rolling shutter cover 23 unfolds along the lower slide rail 4 and extends to the rear tailgate of the cargo box 1 to form a flat-bottom cargo box.

[0035] In the flat-bottom cargo box mode, conventional flat pallets, larger cartons, wooden boards, and wooden frames can be placed on the upper layer of the rolling shutter cover 23, and small suitcases or irregular private items can be placed on the lower layer of the rolling shutter cover 23 to expand the storage capacity.

[0036] like Figure 4 , Figure 5 As shown, in the second state, the adjusting slide rail 6 is rotated 90° and is in a vertical state to guide the rolling shutter cover 23 to enter the transition slide rail 5, and the motor of the rolling shutter mechanism 2 is started to push out the tracked rolling shutter cover 23, and the rolling shutter cover 23 enters the upper slide rail 3 along the transition slide rail 5, and then the motor continues to push the rolling shutter cover 23 to move, unfold along the upper slide rail 23 and extend to the rear rail of the cargo box 1, forming a closed flat-cover cargo box.

[0037] In the flat-top cargo box mode, private items such as suitcases, household appliances, etc. can be placed.

[0038] When the cargo box 1 is in the flat-bottom cargo box mode, the overall load-bearing requirement of the rolling shutter cover 23 should be greater than 500kg. In order to ensure that the cargo box rolling shutter cover 23 and the track meet the strength requirements, a supporting mechanism can be provided on the rolling shutter cover 23 to support it from the bottom upward after unfolding.

[0039] Specifically, support mechanisms can be installed at multiple points of the rolling shutter cover 23, and each support mechanism is mainly composed of a sliding metal plate 7 and a support rod 8. The sliding metal plate 7 can be installed on the rolling shutter cover 23 in a transversely movable manner. The support rod 8 is located below the sliding metal plate 7. One end of the support rod 8 is connected to the rolling shutter cover 23 through a rotating shaft 9, and the other end of the support rod 8 is provided with a magnetic head 10. One end of the sliding metal plate 7 is provided with an adjusting handle 11, and the other end is provided with a return pusher 12 and a return spring 13 for driving the support rod 8 to return.

[0040] In the stored state, the support rod 8 is parallel to the sliding metal plate 7 and is fixed to the sliding metal plate 7 by the magnetic head 10. In the supported state, the magnetic head 10 of the support rod 8 is separated from the sliding metal plate 7 and rotated to a vertical state, with its lower end supported on the inner bottom of the cargo box 1.

[0041] The return pusher 12 has a semicircular groove 121 that can be matched with one arc-shaped end of the support rod 8 and a push head 122 for pushing the support rod 8 to rotate in the opposite direction around the rotation axis 9 .

[0042] The magnetic head 10 of the support rod 8 has a plane for supporting the bottom of the cargo box 1, and a curved surface is provided on one side of the plane to avoid the bottom of the cargo box 1 when the support rod 8 rotates downward.

[0043] When the support rod 8 needs to be unfolded, the adjustment handle 11 is pushed in the direction of the vehicle, so that the magnetic head 10 at the end of the support rod 8 is separated from the sliding metal plate 7 and no longer adsorbed to each other. The support rod 8 falls under the action of gravity and is fixed by suction to the sheet metal of the cargo box floor, supporting the flat-bottom cargo box to carry the goods.

[0044] When the support rod 8 needs to be retracted, the adjusting handle 11 is pushed in the direction outside the vehicle. Since the return pusher 12 needs to match the arc-shaped end of the support rod 8, the support rod 8 can be driven to rotate upward by the pushing head 122 and retracted into the rolling shutter mechanism 2. At this time, the magnetic head 10 can be re-engaged with the sliding metal plate 7, and then the adjusting handle 11 is released, the return spring 13 returns to its position, and the entire support rod 8 is retracted into the rolling shutter mechanism 2.

[0045] It should be noted here that the lower track 4 can be in contact with the upper edge of the wheel bag of the cargo box to ensure the large volume of the flat-bottom cargo box as much as possible.

[0046] The above embodiments are only preferred solutions of the present invention, and are not limited thereto. On this basis, targeted adjustments can be made according to actual needs to obtain different implementation methods. For example, when the cargo box is a split cargo box, the rolling curtain mechanism 2 is arranged at the front side of the cargo box; or, when the cargo box is an integrated cargo box, the rolling curtain mechanism 2 is arranged at the rear side of the second row of seats in the cockpit and passes through the front side of the cargo box, etc. Since there are many possible implementation methods, they will not be described one by one here.

[0047] When the cargo box with a variable track roller shutter mechanism is actually used, the roller shutter system can be adjusted according to different usage conditions. When loading and unloading irregular goods (oil drums, turnover boxes, karts, bicycles, etc.), a large-volume storage system with wheeled bags can be used for loading and storage. When loading and unloading regular square storage (flat pallets, larger cartons, wooden boards, wooden frames, etc.), the track 6 is adjusted to connect to the lower track 4, and the flat-bottom cargo box mode is opened for storage; when loading private items (luggage boxes, electrical components, etc.), the roller shutter system is connected to the upper track 3 by adjusting the track 6 to form a closed flat-cover cargo box mode for storage.

[0048] In addition to the above-mentioned cargo box with a variable track-type rolling shutter mechanism, the present invention also provides a pickup truck, including a vehicle body and a cargo box arranged on the vehicle body, wherein the cargo box is the cargo box with a variable track-type rolling shutter mechanism described above. Regarding the remaining structure of the pickup truck, please refer to the prior art, which will not be repeated in this article.

[0049] The above is a detailed introduction to the cargo box and pickup truck with a variable track roller shutter mechanism provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention, and the description of the above embodiments is only used to help understand the core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
