[0041] Please refer to Figure 1 - Figure 11 This embodiment provides a variable angle skeleton, including:

[0042] Center component 1, wherein a rotating connecting part 110 is provided on the periphery of the center component 1;

[0043] A connecting joint 2 is provided, the number of which corresponds to the number of the rotating connecting parts 110; the connecting joint 2 includes a first connecting part 210 and a second connecting part 220, the first connecting part 210 being rotatably connected to the rotating connecting part 110.

[0044] Adjust the locking member 3, which connects the first connecting part 210 and the rotating connecting part 110, and adjust the tightness of the connection between the two.

[0045] Support rod 4, one end of which is fixedly or rotatably connected to the second connecting part 220, and the support rod 4 can rotate relative to the center member 1 to a plane or be folded.

[0046] Since the support rod 4 is connected to the connecting joint 2, the number of support rods 4 and connecting joint 2 is the same.

[0047] In a preferred embodiment, there are four rotating connecting parts 110. The first connecting part 210 is rotatably connected to the rotating connecting part 110, so that the four support rods 4 located on the same plane can have their angles adjusted to be closer or farther apart. When the adjustment is symmetrical, the length and width of the frame are also adjusted in a standardized manner. During adjustment, the adjusting locking part 3 needs to be in a loose state. After adjusting to the specified length and width, the adjusting locking part 3 is operated to make the first connecting part 210 and the rotating connecting part 110 in a tight fixed state, and the angle between the support rods 4 can no longer be adjusted.

[0048] With the other end of the support rod 4 rotatably connected to the second connecting part 220, this variable angle frame can not only be adjusted in length and width when unfolded, but also folded and stored with the center part 1 as the end center of the support rod 4. Therefore, a transport vehicle using this variable angle frame can be installed in the chassis or corresponding side panel of the vehicle frame to flexibly adjust the length, width, length and height of the vehicle body. There is no need to make complex replacements to the structural rods in the frame. Only the locking part 3 needs to be adjusted to quickly realize the folding, storage and unfolding of the vehicle body. The operation is quick and convenient.

[0049] Please refer to Figure 4 and Figure 5 The central component 1 is a plate structure; the rotating connection part 110 is a rotating connection hole provided on the central component 1, and the number of holes is four evenly distributed; the central axes of the four rotating connection holes are parallel.

[0050] The central axis of the rotatable connection between the support rod 4 and the second connecting part 220 is oriented differently from the central axis of the rotatable connecting hole; in some embodiments, the two are perpendicular.

[0051] Please refer to Figure 2 - Figure 5 It includes a reinforcing connecting end block 5, which has a connector 510 extending into the port of the support rod 4. The support rod 4 is fixedly or rotatably connected to the second connecting part 220 through the reinforcing connecting end block 5.

[0052] When the reinforcing connecting end block 5 and the second connecting part 220 are rotatably connected, the reinforcing connecting end block 5 and the second connecting part 220 are respectively provided with a stop part 520 and a support limiting part 221. When the support rod 4 is unfolded relative to the center member 1, the support limiting part 221 abuts against the stop part 520 to prevent rotation.

[0053] The support rod 4 is generally a hollow rod. If it is directly connected to the second connecting part 220 and fastened with screws and nuts, the rod may be squeezed and deformed, and the rotation may no longer be smooth. Therefore, by adding a reinforcing connecting end block 5 and using a connector 510 to fill the port of the support rod 4, the structural strength of the end of the support rod 4 is increased. Moreover, by using the reinforcing connecting end block 5 to rotate with the second connecting part 220, wear of the support rod 4 can be well avoided.

[0054] Furthermore, by utilizing the positioning stop 520 and support limiting part 221 respectively provided on the reinforcing connecting end block 5 and the second connecting part 220, when the support rod 4 is unfolded relative to the center member 1, the support limiting part 221 abuts against the positioning stop 520 to prevent rotation. Therefore, when this frame is used as the chassis of the vehicle body, or when the frame is adjusted to a suitable position as the side plate of the vehicle frame, it can provide good support when subjected to downward pressure or side leaning by the load being transported, and will not sink or bulge.

[0055] In some embodiments, the stop portion 520 is an extended protrusion structure at the end of the reinforcing connecting block 5, and the support limiting portion 221 is a groove structure. When the extended protrusion structure abuts against the side wall of the groove, it can prevent the reinforcing connecting block 5 from rotating further with the second connecting portion 220.

[0056] Please refer to Figure 4 and Figure 5 The number of the center components 1 is two, and the connecting joint component 2 is provided with a receiving groove 230 corresponding to the rotating connecting part 110.

[0057] The two center components 1 can be arranged vertically, and the receiving groove 230 receives part of the structure of the center component 1. This can effectively prevent the connecting joint component 2 from flipping in an unnecessary direction, and has good structural stability.

[0058] Please refer to Figure 4 and Figure 5The adjusting locking component 3 is a shoulder screw assembly.

[0059] The shoulder screw assembly includes a nut rod and a screw; the outer wall of the nut rod forms the shaft rod, through which a rotating connection hole and a rotating hole on the connecting joint 2 are passed. When the nut rod and the screw are tightened, the center piece 1 and the connecting joint 2 remain fixed, and the support rod 4 cannot rotate.

[0060] Preferably, it also includes a sealing end cap 15, which is detachably connected to the connecting joint 2, sealing the nut rod and the nut part of the screw, and playing a protective role.

[0061] Please refer to Figure 1 - Figure 11 The assembly includes a connecting module 6, a sliding connecting block 9, and a fastener 10. The connecting module 6 has a sliding limiting groove 610 on its periphery, and an installation position 620 at the end of the sliding limiting groove 610. The sliding connecting block 9 is slidably engaged with the sliding limiting groove 610. The connecting module 6 has a connection position 630 at the end of the support rod 4 away from the second connecting part 220, and the support rod 4 is rotatably connected to the connection position 630. The sliding connecting block 9 and the installation position 620 are connected by the fastener 10.

[0062] Please refer to Figure 12 , Figure 13 It includes a reinforcing rod 16, with sliding connecting blocks 9 at both ends of the reinforcing rod 16; the reinforcing rod 16 is rotatably connected to two adjacent connecting modules 6 through the sliding connecting blocks 9 and the fasteners 10; a turning member 17 is provided between the two ends of the reinforcing rod 16, and the reinforcing rod 16 is folded or flattened through the turning member 17.

[0063] In some embodiments, the bending member 17 is a tube with a U-shaped cross-section, and the tube has a clearance notch at the location corresponding to the connecting reinforcing rod 16.

[0064] The reinforcing rod 16 is essentially a rod of fixed length. It assists in determining the length and width dimensions of the aforementioned variable-angle frame before connecting to the connecting module 6, enhancing the overall rigidity of the frame. It can accommodate reinforcing rods 16 of multiple lengths for future use. Furthermore, utilizing the bending or flattening capability of the reinforcing rod 16 via the bending member 17, the frame can still be folded without disconnecting the reinforcing rod 16 from the connecting module 6—a clever design.

[0065] Preferably, the reinforcing rod 16 is rotatably connected to the sliding connecting block 9 via the reinforcing connecting end block 5.

[0066] Please refer to Figure 1 - Figure 11This application also provides a vehicle, including a variable angle frame as described above, wherein the variable angle frame is any part of the vehicle's chassis, frame, or roof.

[0067] Taking a rectangular vehicle as an example, its chassis and roof are positioned opposite each other, the left and right side panels of the frame are positioned opposite each other, and the front and rear side panels of the frame are also positioned opposite each other. Therefore, when the aforementioned variable angle frame is implemented in the vehicle body, it can be flexibly matched to the corresponding positions of the chassis and frame to facilitate subsequent adjustments in length, width, height, and width-height.

[0068] Please refer to Figure 6 and Figure 11 The system includes a connecting module 6, a vertical pole 7, a scissor-type telescopic frame 8, a sliding connecting block 9, a fastener 10, and a connecting sleeve 13; the variable angle frame is the chassis of the vehicle; the scissor-type telescopic frame 8 is the vehicle frame; the connecting module 6 has a sliding limiting groove 610 on its periphery, and the end of the sliding limiting groove 610 has an installation position 620; the sliding connecting block 9 slides with the sliding limiting groove 610; the connecting module 6 has a connection position 6 at the end of the support rod 4 away from the second connecting part 220. 30. The support rod 4 is rotatably connected to the connection position 630; the upright 7 passes through the connection module 6 and is connected to the connection module 6; the connecting sleeve 13 is fitted onto the upright 7; one end of the two support rods 810 on one side of the scissor-type telescopic frame 8 is provided with the sliding connecting block 9 and connected to the connection module 6, and the other support rod 810 is detachably connected to the connecting sleeve 13; the sliding connecting block 9 and the mounting position 620 are connected by the fastener 10; a wheel 11 is detachably connected to the lower end of the upright 7.

[0069] By using the scissor-type telescopic frame 8 as the vehicle frame, the same applies when using a variable angle frame as the chassis of the vehicle. When adjusting the length and width of the vehicle body, it is not necessary to disassemble or replace the components on the frame. Simply operate the adjusting locking part 3 to adjust the variable angle frame that serves as the chassis.

[0070] In addition, the newly designed connecting module 6 and sliding connecting block 9, as the connection nodes between the chassis and the frame, have an additional sliding limit groove 610. This allows the vehicle to be assembled quickly by first using the guide rail groove of the sliding connecting block 9 and the sliding limit groove 610 to make initial contact, and then using the fastener 10 and the mounting position 620 to further tighten it, thereby reducing the complexity of installation and making it easier for personnel to use.

[0071] In some embodiments, the fastener 10 is a screw, the mounting position 620 is a threaded hole, and the sliding connecting block 9 is provided with a corresponding screw through hole.

[0072] Please refer to Figure 5- Figure 7 It includes a handle 12, and the end of the handle 12 is provided with the sliding connecting block 9; the handle 12 is connected to the connecting module 6 through the sliding connecting block 9 and the fastener 10.

[0073] The handle 12 and the sliding connecting block 9 can be rotated.

[0074] Please refer to Figure 5 - Figure 11 The support rod 4 and the connecting module 6 are connected via a connecting joint 2 and a reinforcing connecting end block 5. The first connecting part 210 of the connecting joint 2 is rotatably connected to the connecting module 6, and the first connecting part 210 is connected to the connecting position 630 via the adjusting locking member 3 to adjust the tightness of the connection. The connecting head 510 of the reinforcing connecting end block 5 extends into the port of the support rod 4 and is connected to the support rod 4. The reinforcing connecting end block 5 and the second connecting part 220 of the connecting joint 2 are respectively provided with a stop part 520 and a support limiting part 221. When the support rod 4 is flat relative to the center member 1, the support limiting part 221 abuts against the stop part 520 to prevent rotation.

[0075] The end of the support rod 4 away from the center piece 1 is connected to the connecting module 6 through the connecting joint piece 2 and the reinforcing connecting end block 5. The functional effect achieved is roughly the same as that achieved by the support rod 4 through the connecting joint piece 2 and the reinforcing connecting end block 5 and the center piece 1. This facilitates the angle adjustment of the support rod 4 with the rotating connecting part 110 as the rotation center, and also facilitates the folding and flattening of the chassis.

[0076] Please refer to Figure 6 and Figure 8 , Figure 14 , Figure 15 The connecting sleeve 13 is provided with two connecting plates 1310; the two support rods 810 in the adjacent side plates of the frame are respectively connected to the two connecting plates 1310 to be detachably connected to the upright 7; the distance between the connecting sleeve 13 and the connecting module 6 along the length direction of the upright 7 is adjustable.

[0077] Please refer to Figure 14 In some embodiments, the connecting sleeve 13 needs to be sleeved from the end of the upright 7 to connect with the upright 7.

[0078] Please refer to Figure 15In a preferred embodiment, the connecting sleeve 13 is a component assembled by bolts in half. The connecting sleeve 13 is produced from the same mold, with each half being an evenly divided part, and is assembled into a complete sleeve structure by tightening screws. In this way, when installing the connecting sleeve 13 with the upright 7 or the auxiliary rod 1410, the two halves are simply placed at the required height and then tightened with screws. Compared with the connecting sleeve 13 in the previous embodiment, the installation and disassembly are more convenient and faster.

[0079] The connecting sleeve 13 has a threaded hole. A screw passes through the threaded hole and abuts against the side wall of the upright 7 to fasten the connecting sleeve 13 to the upright 7. The connection between the connecting plate 1310 and the connecting sleeve 13 can be detached by screws. The support rod 810 and the connecting plate 1310 are rotatably connected.

[0080] Please refer to Figures 7-9 and Figure 14 , Figure 15 The system includes a retractable side panel 14; the retractable side panel 14 includes a secondary rod 1410, an extension rod 18, a scissor-type telescopic frame 8, a sliding connecting block 9, a fastener 10, a connecting sleeve 13, and a mating part 1420; there are two secondary rods 1410, each of which is connected to two connecting sleeves 13. The ends of the two support rods 810 on one side of the scissor-type telescopic frame 8 are respectively connected to the two connecting sleeves 13; the ends of the secondary rods 1410 are rotatably connected to the sliding connecting block 9; the sliding connecting block 9 is slidably engaged with the sliding limiting groove 610; the sliding connecting block 9 and the mounting position 620 are connected by the fastener 10; the secondary rod 1410 is detachably connected to the upright 7 through the mating part 1420; the extension rod 18 is connected to the secondary rod 1410.

[0081] The retractable side panel 14 is a panel that can be retracted on the side wall of the vehicle body, making it convenient for users to place more items. When not in use, it can also be retracted to the side wall of the frame. More importantly, it adopts a scissor-type telescopic frame 8, which can also be adapted to the length or width of the vehicle body without disassembling or replacing parts.

[0082] In some embodiments, the connecting module 6 is a rectangular body with four sets of sliding limit grooves 610 and mounting positions 620 on its four sides. The sliding limit grooves 610 and mounting positions 620 on the same side as the left and right sides of the frame can be connected to assembly rods (not shown) to connect the two transport vehicles into one unit.

[0083] Please refer to Figure 14 and Figure 15 In some embodiments, the mating component 1420 is a snap-fit ​​sleeve connected to the auxiliary rod 1410 or the connecting sleeve 13, and the snap-fit ​​sleeve is provided with a snap-fit ​​groove 1421 corresponding to the upright rod 7.

[0084] In some embodiments, the mating component is a magnet, and the upright 7 may be provided with a corresponding magnetic attraction component. The two can be connected by magnetic attraction to keep the retractable side panel 14 in the retracted state.

[0085] The extension rod 18 can be set in the inner wall of the secondary rod 1410, and an adjustment hole is opened on the side wall of the secondary rod 1410. A pressable protruding pin is installed. When the extension rod 18 is pulled out relative to the secondary rod 1410 and moved to a predetermined position, the protruding pin extends out of the adjustment hole to keep the extension rod 18 and the secondary rod 1410 relatively fixed.

[0086] Alternatively, the extension rod 18 can be directly fixed to one end of the auxiliary rod 1410 by bolts to achieve length adjustment of the auxiliary rod 1410.

[0087] The upright 7 can be connected to an extension rod 18, just like the auxiliary rod 1410, so that its length can be adjusted.
