Description

Technical Field

[0001] The embodiments of this utility model relate to the field of transport vehicle bed technology, specifically, to a folding vehicle bed. Background Technology

[0002] In freight transportation, engineering construction, agricultural production, and daily material transfer, truck beds generally adopt an integrated fixed structure design. This means that the length, width, height, and internal capacity of the truck bed are fixed during manufacturing and cannot be adapted to actual transportation needs during use. When transporting long goods, the capacity of traditional fixed-size truck beds is often insufficient. The portion of the goods that exceeds the truck bed's dimensions requires additional binding and securing measures. This not only increases the complexity and labor intensity of loading and unloading operations but also poses safety hazards such as goods falling off or tilting during transportation. Furthermore, it may lead to violations due to exceeding the vehicle's approved loading dimensions. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a folding truck bed, which solves the technical problem that the existing truck beds generally adopt an integrated fixed structure design, which cannot adapt to goods of different lengths and sizes, and also poses safety hazards such as goods falling off and tilting during transportation.

[0006] For example, in a folding truck bed provided in at least one embodiment of the present invention, a snap-fit ​​groove is provided on the side plate adjacent to the swing plate, and a snap-fit ​​member is rotatably provided on the swing plate. The snap-fit ​​member is configured such that when the swing plate is in the enclosed position, the snap-fit ​​member can rotate to snap-fit ​​with the snap-fit ​​groove or unsnap to fix or release the swing plate.

[0007] For example, in a folding truck bed provided in at least one embodiment of the present invention, the extension plate is oscillatingly connected to the oscillating plate via a oscillating shaft; The swing plate is provided with a first insertion hole, the axis of the first insertion hole is parallel to the axis of the swing shaft, and the first insertion holes are spaced apart on one side of the swing shaft. The extension plate is provided with a second insertion hole that matches the first insertion hole. When the extension plate is configured to swing to a storage position that overlaps with the swing plate, it can be connected to the swing plate via a first fastener passing through the first and second insertion holes.

[0008] For example, in at least one embodiment of the present invention, a folding truck bed is provided, which further includes: a support frame disposed at the lower part of the bottom plate; The support rod is movable within the support frame. The support rod can be moved out of the support frame and carry the swing plate and extension plate.

[0009] For example, in a folding truck bed provided by at least one embodiment of the present invention, the swing plate has a swing frame portion, the extension plate has an extension frame portion, and when the extension plate is configured to swing to an extension position coplanar with the swing plate, the extension frame portion and the swing frame portion are arranged adjacent to each other. The support rod has a support groove for accommodating and supporting the extension frame and the swing frame.

[0010] For example, in at least one embodiment of this utility model, a flexible pad is provided at the bottom of the support groove in a folding truck bed.

[0011] For example, in at least one embodiment of the present invention, a folding truck bed is provided in which the support frame and the support rod are fixedly connected by a second fastener.

[0012] For example, in a folding truck bed provided by at least one embodiment of the present invention, the support frame has a third insertion hole, the support rod has at least two fourth insertion holes, the fourth insertion holes are spaced apart along the length of the support rod, and the second fastener can pass through the third insertion hole and one of the fourth insertion holes to fix the support frame and the support rod.

[0013] For example, in at least one embodiment of the present invention, a folding truck bed is provided, wherein the second fastener is movably disposed at the bottom of the base plate, and further includes: The elastic element, with one end set on the support frame and the other end set on the second fastener, can provide elastic tension for the second fastener to move toward the support frame.

[0014] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the extension plate can rotate relative to the swing plate around the swing axis, and can swing to overlap with the swing plate, with the plate surfaces parallel and close together. At this time, the extension plate does not occupy extra space, making it easy to compactly store the truck bed. Alternatively, it can swing to be coplanar with the swing plate, with the plate surfaces flush and extending in the same direction. At this time, the extension plate and the swing plate together form a longer load-bearing plane, further expanding the load-bearing area of ​​the truck bed. Attached Figure Description

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figures 1-6 As shown, it illustrates a folding truck bed 400 in one embodiment of the present invention, which can form a closed enclosed space for loading loose goods, and can also expand the structure to form a larger planar load-bearing area for placing extra-long goods. The overall structure is compact and easy to operate, and is suitable for various transportation scenarios such as freight and engineering.

[0025] The bottom plate 100 is the basic load-bearing component of the truck bed 400. It is flat and is used to directly carry goods. Its upper edge is connected to the four side plates 200, which together enclose and form the main space of the truck bed 400. Four side plates 200 are arranged along the four edges of the bottom plate 100. When perpendicular to the bottom plate 100, they together form the four sides of the truck bed 400. At least one side plate 200 is sway-connected to the bottom plate 100 by means of a hinge or pivot. This side plate 200 is defined as a sway plate 210. In this example, there is one sway plate 210. The sway plate 210 can rotate relative to the bottom plate 100 around the connecting shaft. It can swing to be perpendicular to the bottom plate 100 and form a closed enclosure together with the other side plates 200. At this time, the sway plate 210 is in the enclosed position, or it swings to be parallel to the bottom plate 100. At this time, the plate surface of the sway plate 210 is coplanar with the plate surface of the bottom plate 100 and becomes an extension of the bearing area of ​​the bottom plate 100. At this time, the sway plate 210 is in the bearing position.

[0026] An extension plate 300 is rotatably connected to the swing plate 210. The extension plate 300 is flat and is swayed on the swing plate 210 via a swing shaft 212, such as a hinge or pin. Specifically, it is connected to the back side of the swing plate 210 away from the interior of the truck bed 400. That is, when the swing plate 210 is in the enclosed position, the extension plate 300 is located on the outside side of the truck bed 400. The extension plate 300 can rotate relative to the swing plate 210 around the swing shaft 212. It can swing to overlap with the swing plate 210, with the plate surfaces parallel and close together. At this time, the extension plate 300 does not occupy extra space, making it easy for the truck bed 400 to be compactly stored. Alternatively, it can swing to be coplanar with the swing plate 210, with the plate surfaces flush and extending in the same direction. At this time, the extension plate 300 and the swing plate 210 together form a longer load-bearing plane, further expanding the load-bearing area of ​​the truck bed 400.

[0027] The side plate 200 adjacent to the swing plate 210, i.e., the side plate 200 that fits against the edge of the swing plate 210, is provided with a snap-fit ​​groove 220, which is a concave groove structure used to cooperate with the snap-fit ​​piece 211 to fix the swing plate 210. The snap-fit ​​piece 211 is rotatably mounted on the swing plate 210. If connected by a pin, it can rotate around the pin, and its shape matches the snap-fit ​​groove 220. When the swing plate 210 is in the enclosed position, the snap-fit ​​piece 211 can rotate to be embedded in the snap-fit ​​groove 220, realizing the rigid fixation of the swing plate 210 and the adjacent side plate 200, which is the snap-fit ​​state; when it is necessary to swing the swing plate 210, the snap-fit ​​piece 211 is rotated in the opposite direction to disengage it from the snap-fit ​​groove 220, thereby releasing the fixation, which is the release state.

[0028] Furthermore, the swing plate 210 has a first insertion hole 213, the axis of which is parallel to the axis of the swing shaft 212 of the extension plate 300, ensuring that the holes are aligned when the extension plates 300 are stacked. The first insertion hole 213 is located on one side of the swing shaft 212, corresponding to the swing path of the extension plate 300. The extension plate 300 has a second insertion hole 310, the position of which matches the first insertion hole 213. When the extension plate 300 is in the storage position, the two holes are aligned. When the extension plate 300 swings to the storage position and overlaps with the swing plate 210, the first fastener 500 is inserted into the aligned first insertion hole 213 and second insertion hole 310 to fix the extension plate 300 and the swing plate 210, preventing the extension plate 300 from swinging accidentally during transportation. The first fastener 500 can be a pin, bolt, etc.

[0029] A support frame 800 is fixedly installed at the lower part of the base plate 100. The support frame 800 is a frame-shaped structure with an internal space for accommodating the support rod 900. The support rod 900 is a rod-shaped or frame-shaped structure and is movably installed within the support frame 800. It can slide out or retract along the length of the support frame 800. When the support rod 900 moves out of the support frame 800, the swing plate 210 swings to the bearing position and the extension plate 300 swings to the extension position. The support rod 900 can support the swing plate 210 and the extension plate 300, preventing them from sagging and deforming due to the load.

[0030] The lower edge of the swing plate 210 is provided with a swing frame portion 230, and the lower edge of the extension plate 300 is provided with an extension frame portion 320. Both the swing frame portion 230 and the extension frame portion 320 are borders protruding along the edges. When the extension plate 300 is in the extended position, the extension frame portion 320 is adjacent to and aligned with the swing frame portion 230. The top of the support rod 900 has a support groove 920, the shape of which matches the swing frame 230 and the extension frame 320. Its size can be appropriately larger than the sum of the swing frame 230 and the extension frame 320. The support groove 920 is used to accommodate and support the extension frame 320 and the swing frame 230, dispersing force through surface contact and improving support stability. The bottom of the support groove 920 is provided with a flexible padding layer 910, such as a rubber pad or foam pad, to buffer the pressure of the goods, prevent wear caused by hard contact between the swing frame 230, the extension frame 320 and the support rod 900, and simultaneously enhance friction to prevent slippage.

[0031] Furthermore, the support frame 800 has a third insertion hole 810, and the support rod 900 has a fourth insertion hole 930. There are at least two fourth insertion holes 930, spaced apart along the length of the support rod 900. When the support rod 900 extends to the required length, the second fastener 600 is passed through the third insertion hole 810 of the support frame 800 and one of the fourth insertion holes 930 of the support rod 900 to fix the position of the support rod 900. When the support length needs to be adjusted, the second fastener 600 is pulled out, the support rod 900 is slid until it aligns with the corresponding fourth insertion hole 930, and then reinserted. The second fastener 600 can be a pin, bolt, etc.

[0032] Furthermore, the support frame 800 is also provided with an elastic element 700. One end of the elastic element 700 is connected to the support frame 800, and the other end is connected to the second fastener 600. Its elastic force always causes the second fastener 600 to move towards the support frame 800, that is, to apply a pulling force in the direction of insertion into the third insertion hole 810 and the fourth insertion hole 930. This can prevent the second fastener 600 from accidentally falling off during transportation and ensure that the support rod 900 is securely fixed. When it is necessary to adjust the support rod 900, it is only necessary to overcome the pulling force of the elastic element 700 and pull out the second fastener 600. The operation is convenient. The elastic element 700 can be a spring, elastic rope, etc.

[0033] Specifically, in the initial state, the swing plate 210 is perpendicular to the base plate 100 and is in the enclosed position. When the snap fastener 211 rotates to snap into the snap slot 220 of the adjacent side plate 200, the swing plate 210 is fixed. At this time, the four side plates 200 and the base plate 100 enclose the closed cargo bed 400 space for loading loose goods and preventing them from falling. At this time, the extension plate 300 is in the storage position and overlaps with the swing plate 210. The first fastener 500 passes through the first insertion hole 213 and the second insertion hole 310 to fix the extension plate 300 on the back side of the swing plate 210 without occupying extra space. The support rod 900 is retracted into the support frame 800. The second fastener 600 passes through the third insertion hole 810 of the support frame 800 and the innermost fourth insertion hole 930 of the support rod 900 to fix the support rod 900. The elastic member 700 is in a naturally stretched state, holding the second fastener 600 to prevent it from falling off.

[0034] When expansion is required, the tension of the elastic element 700 is overcome, the second fastener 600 is pulled out, and the support rod 900 is slid outward from the support frame 800 until its support groove 920 can be aligned with the swing frame portion 230 of the swing plate 210 and the extension frame portion 320 of the extension plate 300, which are about to be flipped down. The snap fastener 211 is rotated in the opposite direction to disengage it from the snap fastener groove 220 of the adjacent side plate 200, thus releasing the fixation on the swing plate 210. Then, the swing plate 210 is rotated around the swing axis 212 until it swings to a bearing position parallel to the base plate 100. At this time, the plate surface of the swing plate 210 is coplanar with the base plate 100, forming a preliminary expanded bearing plane. Pull out the first fastener 500 to release the fixation between the extension plate 300 and the swing plate 210. Rotate the extension plate 300 away from the swing plate 210 around the swing axis 212 until it swings to the extension position coplanar with the swing plate 210. At this time, the surfaces of the extension plate 300 and the swing plate 210 are flush, forming a longer bearing plane together, and the extension frame 320 and the swing frame 230 are adjacent and aligned. The support groove 920 accommodates and supports the swing frame 230 and the extension frame 320. The flexible pad 910 is in contact with the frame at this time to buffer the force and prevent slippage. At this time, the third insertion hole 810 of the support frame 800 is aligned with a fourth insertion hole 930 of the support rod 900. Under the pulling force of the elastic member 700, the second fastener 600 automatically inserts into the aligned third insertion hole 810 and fourth insertion hole 930 to fix the position of the support rod 900. At this point, the base plate 100, the swing plate 210, and the extension plate 300 form a continuous large planar load-bearing area, and the support rod 900 provides stable support at the free end, which can safely carry extra-long goods.
