It will be apparent, however, to one skilled in the art, that embodiments of the invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring embodiments of the present invention.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The following detailed description of the preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.

The utility model provides a folding container 100, folding container 100 include chassis 110 and the headwall 120 that is located chassis 110 length direction's tip. As shown in fig. 1 to 8, fig. 1 to 8 show only schematic views of the connection portions of the bottom frame 110 and the end walls 120 of the folding container 100 for the sake of brevity.

As shown in fig. 1 to 8, in the present preferred embodiment, two end walls 120 of the folding container 100 are pivotally connected to both ends of the base frame 110, respectively, i.e., the two end walls 120 are pivotally disposed with respect to the base frame 110. Preferably, an end of each end wall 120 facing the base frame 110 is provided with a connecting arm 124 for pivotal connection with the base frame 110. Thus, the headwall 120 has a transport position (i.e., a collapsed position), a vertical position, and an extended position.

As shown in fig. 1 and 5, when the end walls 120 are in the transportation position, the end walls 120 are stacked on the bottom frame 110, and the folding container 100 has a small volume and is convenient to transport. As shown in fig. 2, 6 and 8, when the end walls 120 are substantially perpendicular to the base frame 110, the end walls 120 are in a vertical position where the collapsed container 100 can be used to load cargo. As shown in fig. 3 and 7, when the end walls 120 are substantially flush with the chassis 110, the end walls 120 are in the deployed position, and the end walls 120 may serve as a transport platform for transporting cargo to the chassis 110. For example, when the folding container 100 is used for a transfer vehicle, the vehicle to be transferred may be moved onto the chassis 110 via the end wall 120.

As shown in fig. 4 to 7, in particular, the folding container 100 includes a first rotation axis and a second rotation axis. The connecting arm 124 is provided with a first pivot hole 124a and a second pivot hole 124 b. The base frame 110 is provided with a first rotation hole 113 and a second rotation hole 114. When the end wall 120 and the bottom frame 110 are perpendicular, the first pivot hole 124a and the second rotation hole 114 are coaxial, and the second pivot hole 124b and the first rotation hole 113 are coaxial. Thus, when only the first rotation shaft is inserted into the first pivot hole 124a and the second pivot hole 114, the end wall 120 is pivotally connected to the base frame 110 by the first rotation shaft. When only the second rotation shaft is inserted into the second pivot hole 124b and the first rotation hole 113, the end wall 120 is pivotally connected to the base frame 110 by the second rotation shaft. When the end wall 120 is in the vertical position, the first rotation shaft is inserted into the first pivot hole 124a and the second rotation hole 114, and the second rotation shaft is inserted into the second pivot hole 124b and the first rotation hole 113, so that the end wall 120 can be fixed on the bottom frame 110. Preferably, the first rotation hole 113 is positioned above the second rotation hole 114 in a height direction of the bottom chassis 110. The second rotation shaft is inserted into the second pivot hole 124b and the first rotation hole 113 when the headwall 120 is rotated between the transportation position and the vertical position. The first rotation shaft is inserted into the first pivot hole 124a and the second rotation hole 114 when the headwall 120 is shifted between the vertical position and the unfolded position. Thereby reducing the swing arm of the headwall 120.

As shown in fig. 1 to 7, the folding container 100 includes a hitch mechanism 180, and the hitch mechanism 180 includes a hitch seat 130 for engaging with a hitch device (such as a lifting device, or a conventional connector such as a twist lock). The hitch seat 130 is pivotally connected to the headwall 120. In the preferred embodiment, the coupling mechanism further includes a coupling seat positioning pin 140. The bottom chassis 110 has a first positioning hole 111, and the coupling seat 130 has a through hole. The coupling seat positioning pin 140 detachably passes through the through hole and the first positioning hole 111. Specifically, when the coupling seat 130 is located at the first position, the first positioning hole 111 and the through hole are coaxial. At this time, the coupling seat positioning pin 140 sequentially penetrates through the through hole and the first positioning hole 111, so that the end wall 120 is prevented from pivoting, and the end wall 120 is fixed at the transportation position. When the hitch coupler pins 140 are removed from the first alignment holes 111, the headwall 120 may be rotated relative to the base frame 110 to rotate the headwall 120 between the transport position, the upright position, and the deployed position. Therefore, the coupling seat 130 and the end wall 120 rotate together, when the end wall 120 rotates relative to the underframe 110, extra operation on the coupling seat 130 is not needed manually, and potential safety hazards caused by manual misoperation are avoided.

Preferably, as shown in fig. 5, the coupling mechanism further includes a coupling member 150 pivotally connected to the bottom chassis 110, and the first positioning hole 111 is provided on the coupling member 150. For example, the link 150 may be pivotally connected to the base frame 110, and when it is desired to position the link 130 at the first position, the first positioning hole 111 of the link 150 may be aligned with the first pivot hole 124a and fixed using the link positioning pin 140. After the coupling seat positioning pin 140 is detached, the coupling member 150 can rotate under the action of gravity, so as to avoid influencing the rotation of the end wall 120.

In the present preferred embodiment, the outer end surface of the headwall 120 (in other words, the upper surface when the headwall 120 is in the transportation position, the outer end surface away from the bottom chassis 110 when the headwall 120 is in the vertical position) has a receiving portion 122 recessed downward, and the depth of the receiving portion 122 is greater than the height of the hanging seat 130. A support 123 is arranged in the accommodating part 122, and one end of the hanging seat 130 far away from the through hole is pivotally connected to the support 123. Therefore, after the coupling seat positioning pin 140 is removed from the first positioning hole 111, the coupling seat 130 can rotate around the support 123. In the preferred embodiment, the hanging base 130 can rotate about the support 123 by approximately 180 °.

In the preferred embodiment, a part of the connecting arm 124 is disposed in the accommodating portion 122, one side surface of the connecting arm 124 is attached to one inner wall surface of the accommodating portion 122, and a part of the connecting arm 124 disposed in the accommodating portion 122 is provided with the second positioning hole 121.

In the preferred embodiment, the coupling seat positioning pin 140 is configured to detachably pass through the through hole and the second positioning hole 121 and position the coupling seat 130 at the second position, so that the coupling seat 130 pivots with the pivoting of the headwall 120. Specifically, the coupling seat 130 rotates by about 180 ° from the first position to the second position around the support 123, at this time, the second positioning hole 121 and the through hole are coaxial, and the coupling seat positioning pin 140 penetrates through the through hole and then extends into the second positioning hole 121, so that the coupling seat 130 can be fixed at the second position. Thus, the hitch seat 130 can pivot together with the headwall 120, and the hitch seat 130 does not swing when the hitch seat 130 rotates with the headwall 120. When the end wall 120 needs to be fixed in a transportation state, the coupling seat positioning pin 140 is detached from the second positioning hole 121, so that the coupling seat 130 can rotate from the second position to the first position, and then the coupling seat positioning pin 140 penetrates out of the through hole and extends into the first positioning hole 111, so that the end wall 120 can be fixed on the bottom frame 110 through the coupling seat 130.

In the preferred embodiment, when the coupling seat 130 is fixed at the second position, the coupling seat 130 is located in the accommodating portion 122. Therefore, the hanging seat 130 is prevented from being higher than the end wall 120, and when the end wall 120 is in the unfolded position, the part of the hanging seat 130 protruding out of the end wall 120 abuts against the floor, so that the end wall 120 is prevented from being suspended.

Preferably, the first pivot hole 124a and the first positioning hole 111 are coaxial when the linkage seat 130 is positioned at the first position. At this time, the coupling seat positioning pin 140 penetrates through the through hole and the first positioning hole 111, and then extends into the first pivot hole 124 a. Thereby, the end wall 120 stacked on the bottom chassis 110 can be prevented from being tilted.

In the preferred embodiment, the hanging seat 130 includes a corner member 131, and when the hanging seat 130 is fixed at the first position, the corner member 131 is disposed along the horizontal direction.

In the preferred embodiment, the bottom frame 110 has a bottom corner member 112, and the coupling seat 130 is fixed at the first position, and the corner member 131 is located above the bottom corner member 112 along the height direction of the bottom frame 110. Thus, the corner pieces 131 and bottom corner pieces 112 cooperate when the end walls 120 are in the transport position, in such a way that the corner pieces 131 and bottom corner pieces 112 can both be standard container corner pieces, so that a plurality of folding containers 100 can be stacked one on top of the other.

According to the utility model discloses a folding container 100, folding container 100 include to link mechanism 180, and the seat 130 is hung to linking of linking mechanism 180 and headwall 120 rotate together, consequently, rotate the in-process for chassis 110 at headwall 120, need not the manual work and carry out extra operation to linking seat 130, have avoided the potential safety hazard that arouses by artifical maloperation.

As shown in fig. 8 to 12, in the present embodiment, the folding container 100 further includes a balancing device 190. The balancing device 190 includes an elastic member 160, a rotating member 171, a mounting seat 172 and a pin. The rotating member 171, the mounting seat 172 and the pin constitute a rotating assembly 170. The mount 172 is fixed to the chassis 110. The mounting block 172 is provided with a first pin shaft hole. The rotating member 171 is provided with a second pin shaft hole 176 and a connecting hole 175. A pin shaft 177 is inserted through the first and second pin shaft holes 176 to pivotally connect the rotating member 171 to the mounting base 172.

The rotation member 171 includes an inner stopper 173 and an outer stopper 174. The outer surface of the inner stopper 173 and the outer surface of the outer stopper 174 are located on the positioning circle. The center of the positioning circle is on the axis of the pin shaft 177. The distance between the portion of the rotating member 171 between the inner stopper 173 and the outer stopper 174 and the axis of the pin shaft 177 is smaller than the radius of the positioning circle.

Thus, when the rotation member 171 is perpendicular to the base frame 110 (i.e., the rotation member 171 is in the upright position), the inner stopper 173 abuts against the bottom plate of the mounting seat 172. During the rotation of the end wall 120 from the vertical position to the folded position, the rotation member 171 cannot rotate in the counterclockwise direction (E direction) of fig. 10 about the pin shaft 177 and is always located at the upright position. Thus, during the rotation of the rotation member 171, the spring is stretched, and the elastic force of the spring can resist the weight of the end wall 120, i.e., the elastic force of the spring provides resistance to the rotation of the end wall to slow down the rotation speed of the end wall 120.

The rotary member 171 is always in the upright position during rotation of the headwall 120 from the folded position to the upright position. Thus, the spring is always in a stretched state during the rotation of the rotation member 171, and the elastic force of the spring can resist the gravity of the end wall 120, i.e., the elastic force of the spring provides a restoring force for the rotation of the end wall, thereby facilitating the rotation of the end wall 120 from the folded position to the vertical position.

During the rotation of the end wall 120 from the vertical position to the extended position, the rotating member 171 rotates along with the rotation of the end wall 120 from the vertical position to the predetermined angle of the rotating member about the pin 177 in the clockwise direction (direction F) of fig. 12 during the rotation of the end wall 120 to the predetermined angle of the end wall. At this time, the rotating member 171 is in an inclined position (i.e., the rotating member 171 is inclined outward with respect to the base frame 110), the outer stopper 174 abuts against the bottom plate of the mounting seat 172, and the rotating member 171 cannot continue to rotate in the direction F. Thus, the rotation member 171 is always in the inclined position as the headwall 120 continues to rotate from the headwall predetermined angle to the deployed position. Thus, when the end wall 120 continues to rotate from the end wall preset angle to the extended position, the spring is stretched, and at this time, the elastic force of the spring can resist the gravity of the end wall 120, that is, the elastic force of the spring provides resistance for the rotation of the end wall, so as to slow down the rotation speed of the end wall 120.

The rotation member 171 is always located at the inclined position during the rotation of the headwall 120 from the unfolded position to the vertical position when the headwall 120 is rotated to the predetermined angle. Thus, in the process that the end wall 120 rotates to the preset angle of the end wall, the spring is always stretched, and the elastic force of the spring can resist the gravity of the end wall 120, that is, the elastic force of the spring provides restoring force for the rotation of the end wall, thereby facilitating the rotation of the end wall 120 from the unfolded position to the vertical position.

When the headwall 120 is rotated from the headwall predetermined angle to the vertical position, the rotation member 171 is rotated from the inclined position to the upright position. During this process, the spring may be in a pre-tensioned state.

Preferably, the mounting seat 172 includes a base plate and two spaced apart connection plates disposed on the base plate. The first pin shaft hole is arranged on the connecting plate. When the rotation member 171 is perpendicular to the bottom chassis 110, the inner stopper 173 abuts against the top plane of the bottom plate, so that the rotation member 171 cannot rotate further in the direction E. When the rotating member is in the inclined position, the outer stopper 174 abuts against the base plate so that the rotating member 171 cannot continue to rotate in the direction F.

The elastic member 160 may be a spring. One end of the spring is pivotally connected to the end wall. The other end of the spring is connected to the rotation member through a connection hole 175. During rotation of the headwall, the spring force resists the weight of the headwall.

In the present embodiment, when the headwall 120 is in the vertical position and the folded position, the inner stopper 173 of the rotor 171 abuts against the top plane of the base plate. Thus, as the headwall rotates between the upright position and the collapsed position, the spring is stretched and the spring force of the spring opposes the weight of the headwall. When the end wall 120 is at the predetermined position (at this time, the rotation member 171 is at the inclined position), the outer stopper 174 abuts against the base plate. Thus, as the headwall rotates between the preset and deployed positions, the spring is stretched and the spring force of the spring opposes the weight of the headwall.

In this embodiment, when the end wall 120 rotates from the vertical position to the folded position or the unfolded position, the spring of the balancing device 190 provides resistance, so as to slow down the rotation speed of the end wall 120 and prevent the end wall 120 from being damaged. The springs of the counterbalance 190 provide a restoring force to facilitate the operation of rotating the end wall 120 when the end wall 120 is rotated from the folded position or the unfolded position to the vertical position.

The following will illustrate the use of the foldable container 100 of the present invention in the handling process of a large vehicle, such as a bus, for example. In the initial state of the folding container 100 according to the present embodiment, the end wall 120 is fixed to the transport position, and the coupling seat 130 is fixed to the first position.

Step one, as shown in fig. 4, detaching the coupling seat positioning pin 140 from the first positioning hole 111; then the hanging seat 130 is rotated by approximately 180 degrees around the support 123, even if the hanging seat 130 is rotated by 180 degrees in the direction A, the hanging seat 130 is rotated to the second position; the coupling seat positioning pin 140 penetrates through the through hole and then extends into the second positioning hole 121, so as to fix the coupling seat 130 on the end wall 120.

Step two, enabling the second rotating shaft to sequentially penetrate through the first rotating hole 113 and the second pivoting hole 124 b; then in the direction B of fig. 6, the headwall 120 is rotated approximately 90 ° about the second axis of rotation, rotating the headwall 120 from the transport position to the vertical position, as shown in fig. 2; the first rotating shaft penetrates through the second rotating hole 114 and the first pivot hole 124a in sequence, and the second rotating shaft is detached from the second pivot hole 124 b; in direction D of fig. 7, the endwall 120 is rotated approximately 90 about the first axis of rotation, rotating the endwall 120 from the upright position to the deployed position, as shown in fig. 3.

And step three, driving the bus to be transported into the bottom frame 110 from the surface, far away from the ground, of the end wall 120.

Step four, in the direction C of fig. 6, the end wall 120 is rotated by approximately 90 ° around the first rotation axis, so that the end wall 120 is rotated from the deployed position to the vertical position, as shown in fig. 2; the second rotating shaft is sequentially passed through the first rotating hole 113 and the second pivoting hole 124b to fix the end wall 120 in a vertical position, thereby completing the loading.

In the process of loading, the first step is manually fixed on the first position of the linkage hanging seat 130, and the rest steps are not required to operate the linkage hanging seat 130, so that the whole loading process is simple, convenient and fast, and manual misoperation is avoided.
