[0025] See also Figure 1 and Figure 2 The present invention discloses a folding box for transporting vehicles, comprising a base frame 1, a foldable end frame 2, and a fixed frame 4 and a movable frame 5 for loading vehicles. In this embodiment, the box comprises two sets of fixed frames 4 and two sets of movable frames 5. The fixed frames 4 are fixed to the base frame 1, and the movable frames 5 have a folded state lying flat on the base frame 1 and a propped-up use state. Figure 1 and Figure 2 Of the two movable rod frames on the middle chassis 1 , one movable frame 5 is in a folded state, and the other movable frame 5 is in a use state, so as to better illustrate the detachable connection relationship between the movable frame 5 and the folding box in the present invention.

[0026] The chassis 1 consists of bottom side beams 11, bottom end beams, bottom cross beams, and bottom longitudinal beams. The bottom side beams 11 are located on either side of the chassis 1 in its width direction, while the bottom end beams are located on either side of the chassis 1 in its length direction. The bottom side beams 11 and the bottom end beams are welded together using bottom angle fittings. The bottom cross beams and bottom longitudinal beams are fixed in the space enclosed by the bottom side beams 11 and the bottom end beams. Two sets of symmetrical track slabs are laid and fixed to the chassis 1. Each set of track slabs, together with the chassis 1 structure, forms a fixed frame 4.

[0027] The end frame 2 consists of a top crossbeam and corner posts 21 fixed to each end of the top crossbeam. Top corner fittings are secured between the corner posts 21 and the top crossbeam. The bottoms of both corner posts 21 are connected to the base frame 1 via a hinge assembly 3. The hinge assembly 3 includes an outer hinge 31 and an inner hinge. The inner hinge is pivotally connected to the interior of the outer hinge 31. The corner posts 21 are welded to the inner hinge. The outer hinge 31 is secured to the bottom corner fittings and the bottom end beam.

[0028] Each set of movable frames 5 includes two lane plates and a frame body outside the lane plates. The movable frames 5 have a first end and a second end along their length. The first end of the movable frame 5 is detachably connected to the base frame 1 via a support column 6, and the second end of the movable frame 5 is detachably connected to the end frame 2 via a locking pin 56 that is retractable along the width of the movable frame 5. When both ends of the movable frame 5 are disconnected from their corresponding support structures, the movable frame 5 can be placed flat on top of the fixed frame 4 and secured with ropes, allowing the movable frame 5 to be folded and placed inside the box. The specific structure is as follows:

[0029] Combine Figure 1 and Figure 2 The support column 6 is an elongated cylindrical structure, with a first end and a second end along its length. A vertical guide slot 12 is defined in the bottom side beam 11. The first end of the support column 6 engages with the guide slot 12 for insertion and removal. Corresponding through-holes (not shown) are defined in both the end and the sidewall of the guide slot 12 to secure the two with a latch. The guide slot 12 vertically positions the support column 6, providing support for the first end of the movable frame 5.

[0030] See Figure 3 A round rod 51 is clamped to the bottom of the first end of the movable frame 5 via a clamping structure. The axis of the round rod 51 runs along the width of the movable frame 5. Applying an external force allows the round rod 51 to rotate about its axis. A column sleeve 52 is secured to each end of the round rod 51. The outer wall of the column sleeve 52 is welded to the end of the round rod 51, and the axis of the column sleeve 52 is perpendicular to the axis of the round rod 51. The column sleeve 52 serves as the outermost structure of the first end of the movable frame 5 in the width direction and mates with the corresponding support column 6.

[0031] The inner diameter of the column sleeve 52 allows it to fit snugly over the support column 6 and slide along its outer surface. The second end of the support column 6 is provided with a plurality of first mounting holes spaced apart along its length, and the column sleeve 52 is provided with a second mounting hole. The design of these first and second mounting holes is conventional in the art and therefore not shown in the figure. When the second mounting hole aligns with any of the first mounting holes, the column sleeve 52 can be secured to the support column 6 using a latch. In this manner, the first end of the movable frame 5 is slidably mounted on the support column 6, and the latch can be used to secure the movable frame 5 to different heights of the support column 6.

[0032] See Figure 4 To facilitate the folding of the movable frame 5, the guide slot 12 includes an upper slot 121 and a lower slot 122. The upper slot 121 has a larger diameter than the lower slot 122 and has a horizontal notch to accommodate the column sleeve 52 after the movable frame 5 is folded. The lower slot 122 also has a corresponding through-hole for securing the second end of the support column 6 with a latch. To fold the movable frame 5, the latch between the first end of the movable frame 5 and the second end of the support column 6 is first removed, allowing the first end of the movable frame 5 to slide along the column sleeve 52 to the second end of the support column 6, i.e., the column sleeve 52 falls into the upper slot 121. The latch between the first end of the support column 6 and the sidewall of the guide slot 12 is then removed, allowing the support column 6 to be removed and placed flat on the base frame 1. This completes the folding of the first end of the movable frame 5, which can be performed after the second end of the movable frame 5 is folded.

[0033] See Figures 5 to 8 The second end of the movable frame 5 is provided with a fixed block 53 and a sliding assembly, which includes a slider 54, a connecting sleeve 55, and a locking pin 56. A fixed block 53 is welded to both sides of the bottom of each lane plate. Each fixed block 53 has two guide holes 57 extending along the length of the movable frame 5. The two guide holes 57 are also distributed along the length of the movable frame 5.

[0034] Each fixed block 53 corresponds to a slider 54. The slider 54 has a U-shaped cross-section that precisely accommodates the fixed block 53. One side of the fixed block 53 is fixed to the bottom of the movable frame 5, while the other three sides precisely contact and slide with the inner side of the slider 54. Guide posts 58 that extend across guide holes 57 are welded to the sliders 54, allowing the sliders 54 to slide relative to the fixed blocks 53 along the length of the movable frame 5.

[0035] A connecting sleeve 55 is welded to the same-side ends of the four sliders 54 and extends along the width of the movable frame 5. A locking pin 56 is slidably mounted on each end of the connecting sleeve 55. Three interconnected positioning slots are spaced apart along its length. These three positioning slots and their interconnecting slots form an E-shaped slot 7, which extends along the length of the connecting sleeve 55. The locking pin 56 is located within the connecting sleeve 55. A lever 59 is attached to the locking pin 56, which passes through the E-shaped slot 7 and engages with each positioning slot. The lever 59 is constantly movable within the E-shaped slot 7 and can be manually moved to adjust the extension of the locking pin 56 across the width of the movable frame 5. When the lever 59 is in the middle positioning slot, the corresponding locking pin 56 is in the first position. When the lever 59 is in the positioning slot near the end of the connecting sleeve 55, the corresponding locking pin 56 is in the second position. When the lever 59 is in the positioning slot away from the end of the connecting sleeve 55, the corresponding locking pin 56 is in the third position. That is, when the locking pin 56 is located in the third position, the first position, and the second position in sequence, the extended length of the locking pin 56 gradually increases.

[0036] See Figure 9 The two corner posts 21 on the same side have protruding guide rails 22 welded to their opposing webs, running along their lengths. These webs also feature first locating holes 23 for the insertion of locking pins 56, located on the inner sides of the guide rails 22. A vertical connecting guide rail 32 and a second locating hole 33 are provided on opposing sides of the two external hinges 31, located on the inner sides of the connecting guide rails 32. When the end frame 2 is vertically opened, the guide rails 22 and connecting guide rails 32 meet. At this point, the height of the first locating hole 23 is the height at which the second end of the movable frame 5 needs to be secured after loading. The second locating hole 33 is used to secure the second end of the movable frame 5 when it is unloaded and placed flat on the base frame 1.

[0037] When the locking pin 56 is in the first position, the locking pin 56 can move inside the guide rail 22. Figure 5 and Figure 8During the up-and-down movement of the locking pin 56, since the first end of the movable frame 5 is already fixed, the longitudinal displacement caused by the up-and-down movement of the second end is achieved through the sliding structure between the sliding assembly and the fixed plate. At the same time, during the sliding process of the locking pin 56 on the inner side of the guide rail 22, when the height position of the locking pin 56 corresponds to the first positioning hole 23, the lever 59 can be operated to move the locking pin 56 to the second position, and the locking pin 56 is inserted into the first positioning hole 23, thereby fixing the second end of the movable frame 5 to the end frame 2. Figure 6 shown.

[0038] As the locking pin 56 slides inside the guide rail 22, it is blocked by the hinge assembly 3 and the U-shaped angle plate above it. When in the first position, the locking pin 56 can only fall into the bottom of the guide rail 22 and cannot enter the connecting guide rail 32. The lever 59 needs to be operated to move the locking pin 56 to the third position, causing it to retract a certain distance before it can enter the inside of the connecting guide rail 32. Similarly, if it is necessary to ensure that the second end of the movable frame 5 moves vertically when supporting the second end, it is necessary to ensure that the extended portion of the locking pin 56 can still fall into the inside of the guide rail 22 after the locking pin 56 moves out of the connecting guide rail 32. There are two ways to adjust this: one is to consider deepening the guide rail 22, and the other is to promptly operate the lever 59 to move the locking pin 56 to the second position. The latter can further reduce the height of the second end of the movable frame 5 falling in the event of an accident.

[0039] When the locking pin 56 is in the third position, the locking pin 56 can move inside the connecting guide rail 32. During the process of sliding the locking pin 56 up and down, when the height position of the locking pin 56 corresponds to the second positioning hole 33, the lever 59 can be operated to move the locking pin 56 to the first position, and the locking pin 56 is inserted into the second positioning hole 33, and the second end of the movable frame 5 is fixed to the hinge device 3. When the locking pin 56 is inserted into the second positioning hole 33, the second end of the movable frame 5 is folded, as shown in FIG. Figure 7 shown.

[0040] Based on the above support structure, when loading a vehicle, after opening the end frame 2, the first end of the movable frame 5 is fixed at an appropriate height based on the pre-installed vehicle on the fixed frame 4. The support column 6 is removed and inserted into the guide groove 12 and the column sleeve 52. After lifting the first end of the movable frame 5, the support column 6 is fixed to the guide groove 12 and the column sleeve 52 using a latch. The vehicle is then driven into the movable frame 5 using the tilting platform at the outer end of the base frame 1. After the vehicle is fixed, the lever 59 is operated to retract the locking pin 56 to release the lock of the second end of the movable frame 5. The second end of the movable frame 5 is then lifted by a forklift and the lever 59 is operated to extend the locking pin 56 at the height of the first positioning hole 23 to secure the second end of the movable frame 5. When unloading a vehicle, the vehicle on the fixed frame 4 is unloaded first. The lever 59 is then operated to release the lock of the second end of the movable frame 5, and the movable frame 5 is lowered and folded to the second positioning hole 33 to secure it, and the vehicle is driven out. The first end of the movable frame 5 is then folded.

[0041] In summary, the present invention, based on the four-space folding car transport box, optimizes the support structure at both ends of the movable frame 5. The support column 6 at one end, as in the prior art, is replaced with a plug-in type, simplifying its connection to the base frame 1. The support column 6 at the other end is moved to the corner column 21, becoming one with the corner column 21, making more efficient and effective use of the box space. The present invention utilizes the locking pin 56 in conjunction with the end frame 2, eliminating the complex process of manipulating two additional support columns 6 required in the prior art, thereby optimizing the operation method.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
