Description

Folding container for vehicle transportation

Technical Field

The present utility model relates generally to the technical field of container construction and more particularly to a folding container for vehicular transportation.

Background

In recent years, the professional shipping capacity of automobiles can not meet the export requirement of China automobiles, and how to solve the problem of shortage and tension of the automobile shipping capacity, which helps China to manufacture the sea, becomes a urgent problem to be solved.

When the common folding box is used, the end frames are erected for loading, when the empty box returns, the end frames are folded to reduce the height, and a plurality of folding boxes are folded to be used as a container for transportation, so that return transportation cost is reduced. To facilitate the ingress and egress of vehicles from the end of the folding box, the use of wallboard-free folding boxes is becoming more and more widespread, see fig. 1-4. Referring to fig. 1-2, a typical 40 foot standard folding box with a body length of 5 meters for a vehicle is used as an example, and the 40 foot standard folding box is shorter and shorter when loading 3 vehicles, and can only load 2 vehicles. And, the 40 feet standard length folding box has a margin in the length direction when loading 2 cars, resulting in the waste of the remaining length space. If 3 cars are to be accommodated, the length of the folding box is approximately 14-15 meters, exceeding the length of a 40 foot standard folding box. Referring to fig. 3 and 4, the structure of the wallless folding box adapted to load 3 vehicles is generally configured to extend both ends of the chassis of the 40-foot standard folding box outwardly, respectively, such that the extended chassis occupies a lot of space when transported, and thus, an ultra-long folding box exceeding the length of the standard folding box is transported far more than the standard length folding box.

Accordingly, there is a need to provide a folding container for vehicle transportation that at least partially addresses the above-described problems.

Hereinafter, specific embodiments of the present utility model will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the present utility model and not limit the present utility model.

First embodiment

The utility model provides a folding container for vehicle transportation. As shown in fig. 5 to 25, the folding container according to the present utility model includes a main chassis 110, an end frame 120, an extension chassis 130, and a connector. The dimension of the main chassis 110 in the length direction D1 is equal to the dimension of a standard container. The end frame 120 is pivotally connected to an end of the main chassis 110 in the length direction D1 about a first pivot axis AX1 between a folded position and an upright position. The first pivot axis AX1 is parallel to the width direction D2 of the main chassis 110. An opening 121 is formed between the end frame 120 and the main chassis 110 in the upright position for the vehicle 1 to pass through. The extension chassis 130 is movably disposed to the main chassis 110 between a collapsed position and an expanded position. The connection is disposed between the extension chassis 130 and the main chassis 110.

When the extension chassis 130 is in the folded position, the extension chassis 130 does not extend beyond the end of the main chassis 110 in the length direction D1, and the connector does not extend beyond the end of the main chassis 110 in the length direction D1. When the extension chassis 130 is in the deployed position, the free end of the extension chassis 130 extends beyond the end of the main chassis 110 and above the lower surface of the main chassis 110, and the connector extends at least partially beyond the end of the main chassis 110 and provides at least an upward force to the extension chassis 130 such that the extended chassis 130 remains in the deployed position. The extension chassis 130 in the deployed position is for mating with the main chassis 110 to carry the vehicle 1. Wherein the free end of the extension chassis 130 is higher than the lower surface of the main chassis 110, it will be appreciated that the extension chassis 130 is spaced apart from the ground 2 when the main chassis 110 is placed on the ground 2. For example, the free end of the extension chassis 130 in the unfolded position may be flush with the upper surface of the main chassis 110. The free end of the extension chassis 130 in the unfolded position may also be slightly higher than the upper surface of the main chassis 110. The free end of the extension chassis 130 in the deployed position may also be slightly below the upper surface of the main chassis 110.

According to the folding container for vehicle transportation of the present utility model, when the extension chassis 130 is located at the folding position, the extension chassis 130 does not exceed the end of the main chassis 110 along the length direction D1, and the connector does not exceed the end of the main chassis 110 along the length direction D1, at this time, the dimension of the folding container along the length direction D1 is consistent with that of the standard container, thereby facilitating flexible selection of transportation means and further facilitating reduction of transportation cost; when the extension chassis 130 is in the unfolded position, the free end of the extension chassis 130 is beyond the end of the main chassis 110 and above the lower surface of the main chassis 110, and the connector is at least partially beyond the end of the main chassis 110 and provides at least an upward force to the extension chassis 130 so that the extended chassis 130 remains in the unfolded position, the extension chassis 130 in the unfolded position is adapted to cooperate with the main chassis 110 to carry the vehicle 1, at which time the size of the folded container in the length direction D1 is larger than a standard container in order to carry more vehicles 1, thereby facilitating an improved carrying capacity of the folded container.

Referring to fig. 5 to 16, the extension chassis 130 may be movably disposed at the main chassis 110 in the length direction D1. For example, the main chassis 110 may have a first guide member 111. The extension chassis 130 may have a second guide member 131. The first guide member 111 and the second guide member 131 are slidably fitted to each other in the length direction D1 to allow the extension chassis 130 to be slidable with respect to the main chassis 110 in the length direction D1.

For example, the first guide member 111 may be configured as a guide rail, and the second guide member 131 may be configured as a slider.

Referring to fig. 6 to 16, the connection member may be configured as a support 160. One end of the support 160 is movably connected to an end of the main chassis 110. The other end of the support member 130 is used to support the extension chassis 130 when the extension chassis 130 is in the extended position and the other end of the support member 160 extends beyond the end of the main chassis 110. Wherein the other end of the support 160 may be movably connected with the extension chassis 130 so as to be capable of following the extension chassis 130 to move synchronously. Alternatively, the other end of the support 160 may be detachably connected to the extension chassis 130 at the unfolded position, not to follow the movement during the movement of the extension chassis 130, but to manually adjust the posture of the support 160 after the extension chassis 130 is moved to the unfolded position, so that the other end of the support 160 is at a position capable of providing a supporting force to the extension chassis 130.

When the extension chassis 130 is in the extended position, the other end of the supporting member 160 may apply the supporting force to the extension chassis 130 at a middle portion of the extension chassis 130 in the longitudinal direction, or at any other position such as an edge.

Preferably, the other end of the support 160 applies the supporting force to the extension chassis 130 may be a middle portion of the extension chassis 130 in the length direction. This facilitates uniform stress on the extension chassis 130.

Further, the supporting pieces 160 may be disposed at intervals in the width direction of the main chassis 110. In the illustrated embodiment, two support members 160 are provided at either end. The two support frames 160 are disposed opposite to each other.

With continued reference to fig. 6-16, for example, the extension chassis 130 may have guide slots 132. One end of the support 160 is pivotably connected to an end of the main chassis 110. The other end of the support 160 is slidably fitted to the guide groove 132 along the guide path of the guide groove 132. During the movement of the extension chassis 130 with respect to the main chassis 110, the support 160 is synchronously pivoted with respect to the main chassis 110, i.e., the support 160 is synchronously moved following the extension chassis 130. When the extension chassis 130 is located at the unfolded position, the guide groove 132 is located at the bottom of the extension chassis 130, and the other end of the support 160 exceeds the end of the main chassis 110 to support the extension chassis 130 such that the extension chassis 130 is maintained at the unfolded position. At this time, the guide groove 132 is located at the bottom of the extension chassis 130. That is, the extension chassis 130 may be supported by the support 160 to be reliably held in the deployed position, thereby enabling loading of the vehicle 1 and transportation of the vehicle 1.

Referring again to fig. 6 to 16, further, one end of the support 160 is pivotably connected to an end of the main chassis 110 about a fourth pivot axis AX4 parallel to the height direction D3 of the main chassis 110. The other end of the support 160 is slidably fitted to the guide groove 132 along the guide path of the guide groove 132. The first end of the guide groove 132 is farther from the middle of the main chassis 110 in the length direction D1 than the second end of the guide groove 132. The first end of the guide groove 132 is farther from the fourth pivot axis AX4 in the width direction D2 than the second end of the guide groove 132. The other end of the support 160 moves from the first end toward the second end of the guide groove 132 during movement of the extension chassis 130 from the collapsed position to the extended position. That is, the support 160 can pivot synchronously about the fourth pivot axis AX4 during movement of the extension chassis 130 to improve the operating efficiency of the extension chassis 130 in use.

In the embodiment shown in fig. 13 to 15, the guide groove 132 is configured as a first groove section 132a. The first groove segment 132a may be a circular arc-shaped groove segment.

In the embodiment shown in fig. 16, the guide groove 132 may include a first groove section 132a and a second groove section 132b. The first groove segment 132a intersects the length direction D1. The second groove section 132b is parallel to the length direction D1. And the first slot segment 132a is farther from the middle of the main chassis 110 in the length direction D1 than the second slot segment 132b. By providing the first slot segment 132a, the support 160 can be made to pivot during movement of the extension chassis 130 to the extended and collapsed positions. By providing the second slot segment 132b, it is facilitated to increase the length of the extension chassis 130 beyond the main chassis 110 in the length direction D1.

Referring to fig. 5 to 16, extension chassis 130 may be provided at both ends of the main chassis 110, respectively, so that both ends of the main chassis 110 may be extended, respectively, to further increase the overall length of the chassis, thereby achieving higher capacity.

In other embodiments of the present utility model, one of both ends of the main chassis 110 may be provided with an extension chassis 130.

Referring to fig. 7, 9 and 10, the extended position may be an extreme position in which the extension chassis 130 moves away from the main chassis 110.

Referring to fig. 9 and 10, in addition, the folding container for transporting the vehicle 1 may further include a transition frame 140 in the case of the unfolded position as the extreme position of the extension chassis 130. The transition frame 140 is pivotally connected to the free end of the extension chassis 130 about a third pivot axis AX3 parallel to the width direction D2 between a use position and a stowed position. The third pivot axis AX3 is parallel to the first pivot axis AX1. When the transition frame 140 is in the use position, the free end of the transition frame 140 extends outside the extension chassis 130 in the length direction D1 and below the third pivot axis AX3 to allow the vehicle 1 to be transferred from the ground 2 or the like to the extension chassis 130, the main chassis 110, in sequence, via the transition frame 140. When the transition frame 140 is in the stowed position, the free end of the transition frame 140 does not extend beyond the free end of the extension chassis 130 in the length direction D1, e.g., the transition frame 140 may rest against an upper portion of the extension chassis 130. In the case of the transition frame 140, the vehicle 1 is conveniently moved to the main chassis 110 and the extension chassis 130, so that the probability of using the lifting device can be reduced, thereby contributing to cost reduction. Wherein the free end of the transition frame 140 is below the third pivot axis AX3, it is understood that the free end of the transition frame 140 in the use position may be flush with the lower surface of the main chassis 110 or may be below the lower surface of the main chassis 110. Of course, in other embodiments, the free end of the transition frame 140 in the use position may be slightly above the lower surface of the main chassis 110.

In the case where the extension chassis 130 are provided at both ends of the main chassis 110, respectively, the transition frame 140 may be provided only to the extension chassis 130 at one end thereof for the vehicle 1 to move in from one end thereof. Of course, it will be appreciated by those skilled in the art that the transition frame 140 may also be provided to the extension frames 130 at both ends, respectively, for the vehicle 1 to move in from either end of the main frame 110 or to move in from both ends of the main frame 110 at the same time.

Referring to fig. 8, as a modified embodiment of the present embodiment, the extension chassis 130 in the unfolded position can also pivot about the second pivot axis AX2 to the transition position. The free end of the extension chassis 130 in the transitional position is below the second pivot axis AX2 to allow the vehicle 1 to transition from the ground 2 or the like to the extension chassis 130. After the vehicle 1 is moved to the extension chassis 130 or to the main chassis 110 via the extension chassis 130, the extension chassis 130 may be rotated about the second pivot axis AX2 to the deployed position. In this modified embodiment, the connection member may be connected with one of the extension chassis 130 and the main chassis 110, and may be detachably connected with the other of the extension chassis 130 and the main chassis 110 by hooking or the like. For example, the connection member may also be configured as the support member 160. One end of the support 160 is pivotally connected to an end of the main chassis 110 in the length direction D1 about the fourth pivot axis AX4, and the other end of the support 160 is for abutting against the bottom of the extension chassis 130 in the deployed position. Further, the support 160 does not move synchronously with the movement of the extension chassis 130 during the movement of the extension chassis 130 from the collapsed position to the expanded position, and it is necessary to rotate the support 160 manually. In contrast to the embodiments shown in fig. 9 and 10, movement of the extension chassis 130 from the transitional position to the deployed position may require the operation of lifting equipment such as a forklift; the manner of separately providing the transition frame 140 can help to reduce labor intensity, and is convenient to directly operate by manpower, so that the transition frame 140 rotates from the use position to the storage position. Wherein the free end of the extension chassis 130 at the transition position is lower than the second pivot axis AX2, it is understood that the free end of the extension chassis 130 may be flush with the lower surface of the main chassis 110 or may be lower than the lower surface of the main chassis 110. Of course, in other embodiments, the free end of the extension chassis 130 at the transition position may be slightly higher than the lower surface of the main chassis 110.

In the illustrated embodiment, the extension chassis 130 located at one of the two ends of the main chassis 110 may pivot from the deployed position to the transitional position.

As a modification of the present embodiment, the extension chassis 130 may include a first extension frame portion and a second extension frame portion. The first extension frame portion and the second extension frame portion correspond to positions of wheels on the left and right sides of the vehicle 1, respectively. The first extension frame portion and the second extension frame portion are disposed at intervals in the width direction D2. That is, the extension chassis 130 may be of a split-type construction. This facilitates a more effort-efficient operation of moving the portion of the extension chassis 130 between the deployed and stowed positions.

As a modification of the present embodiment, the transition frame 140 may include a first transition frame 140 portion and a second transition frame 140 portion. The first transition frame 140 and the second transition frame 140 are disposed at intervals in the width direction D2. That is, the transition frame 140 is of a split type construction.

The size of the standard container described above may be 40 feet.

According to the folding container of the present embodiment, the extension chassis 130 is provided at an end of the main chassis 110 in the longitudinal direction D1 so as to slide or roll in the longitudinal direction D1, and is a pull-out type structure. In use, the extension chassis 130 is caused to protrude outside the main chassis 110 by the pulling translation. The extension chassis 130 may be provided at intervals in the width direction D2 to form a split type structure, or may be integrated. The extension chassis 130 is located at an end of the main chassis 110, may be mounted to an upper portion of the main chassis 110 through a guide rail, or may be hidden inside the main chassis 110. After the extension chassis 130 is moved outward to the deployed position, the hinge structure provided by the end head can also be rotated downward to rest on the ground 2 as a cab apron for the vehicle 1 to go up and down the container. The extension chassis 130 may also be provided with a small rotating cab apron alone as the transition frame 140 for the vehicle 1 to be placed on and off the container. After the extension chassis 130 is moved to the deployed position, limiting may be achieved by connecting the tie rod 150 to the end frame 120, and a rotational stop may be provided at the end to prevent the extension chassis 130 from hanging down. The lower portion of the extension chassis 130 or the end of the main chassis 110 may have a support 160 that is rotatable. The support 160 may be moved in synchronization with the extension chassis 130, or may be rotated by a manual operation after the extension chassis 130 is withdrawn to provide support to the extension chassis 130.

Second embodiment

The folding container for vehicle transportation according to the second embodiment is the same as or similar to the first embodiment, and the differences are described below.

Referring to fig. 17 to 25, the extension chassis 230 according to the present embodiment is rotatably connected to an end portion of the main chassis 210 in the length direction D1 about a second pivot axis AX2 parallel to the width direction D2. That is, the extension chassis 230 is rotatably mounted to the main chassis 210.

Referring to fig. 18 to 25, further, the guide groove 232 may be extended in an extending direction perpendicular to the second pivot axis AX2. One end of the support 260 is pivotably connected to an end of the main chassis 210 about a fifth pivot axis AX5 parallel to the second pivot axis AX2. The other end of the support 260 is slidably fitted to the guide groove 232 in the extending direction. The first end of the guide groove 232 is farther from the second pivot axis AX2 than the second end of the guide groove 232. The other end of the support 260 moves from the second end to the first end of the guide groove 232 during movement of the extension chassis 230 from the collapsed position to the extended position. In the present embodiment, the support 260 is rotatable about the fifth pivot axis AX5 while the extension chassis 230 is rotatable about the second pivot axis AX2, i.e., the support 260 and the extension chassis 230 are rotated in synchronization. This contributes to an improvement in the operation efficiency.

In the embodiment shown in fig. 25, the fifth pivot axis AX5 is farther from the middle of the main chassis 210 in the length direction D1 than the second pivot axis AX 2.

According to the folding container of the present embodiment, the extension chassis 230 is hinged to an end of the main chassis 210 in a rotatable configuration. In use, the extension chassis 230 is extended out of the main chassis 210 by rotating it. The extension chassis 230 may be configured as two parts in the width direction D2, each of which is rotatable alone, or the extension chassis 230 may be rotated as a unitary structure. The angle of rotation of the extension chassis 230 may be greater than 180 degrees so that the free end of the extension chassis 230 after rotation can rest on the ground 2 to act as a ferry for the vehicle 1 to enter and exit the container. A rotating cab apron can be further arranged at the end of the extension underframe 230 to serve as a transition frame 140, and after the extension underframe 230 rotates outwards for 180 degrees to reach the unfolding position, the single rotating cab apron rotates outwards to be opened and is placed on the ground 2 to serve as a sloping cab apron for the upper and lower containers of the vehicle 1. After the extension chassis 230 is rotated 180 degrees to the unfolded position, a rotation stop bar may be further provided between the end of the main chassis 210 and the extension chassis 230 to prevent the extension chassis 230 from being hung down by fixing and limiting the tie rod 150 with the corner post 122. Auxiliary means for assisting the rotation of the extension chassis 230 may also be provided, such as a booster spring, or a booster mechanism with a connecting rod. The power assisting mechanism with the connecting rod can be a hydraulic cylinder or an electric cylinder with a telescopic rod.

Third embodiment

The folding container for vehicle transportation according to the third embodiment is the same as or similar to the second embodiment, and the differences are described below.

Referring to fig. 17-25, in conjunction with fig. 5-12, in the present embodiment, the corner posts 122 of the end frame 120 are pivotally connected to the main chassis 210 about a first pivot axis AX 1. The corner post 122 has a first stop member (not shown). The extension chassis 230 is pivotally connected to the corner post 122 about a second pivot axis AX2 that is parallel to the first pivot axis AX 1. The extension chassis 230 has a second limiting member (not shown) disposed corresponding to the first limiting member. The second stopper member is adapted to abut against the first stopper member to restrict the extension chassis 230 from pivoting in a direction approaching the main chassis 210 during the pivoting of the extension chassis 230 about the second pivot axis AX2 to the retracted position. In this way, during the rotation of the end frame 120 from the folded position to the upright position about the first pivot axis AX1, the extension chassis 230 can be driven to rotate for a certain stroke about the second pivot axis AX2 in the direction approaching the unfolded position, so as to facilitate more convenient and labor-saving adjustment of the movement of the extension chassis 230 to the unfolded position.

The extension chassis 230 according to the present embodiment may be disposed on the corner post 122 of the folding case, and when the folding corner post 122 is unfolded to the upright position in use, the extension chassis 230 is rotated to the upright position. The bottom of the extension chassis 230 is connected to the corner posts 122 by a hinge structure, and the extension chassis 230 continues to rotate outwardly alone and extends out of the box when the corner posts 122 are erected. The extension chassis 230 may be rotated outwardly by an angle greater than 90 degrees so that it can rest on the ground 2 after rotation as a cab apron for vehicles 1 entering and exiting the container. A rotating cab apron may be further disposed at the end of the extension chassis 230 to serve as a transition frame 140, so that after the rotating cab apron rotates outwards by 90 degrees, the individual end rotating cab apron rotates outwards to open and rest on the ground 2 to serve as an inclined cab apron for the upper and lower containers of the vehicle 1. After rotation, a rotation stop may be provided at the end to prevent the extension chassis 230 from hanging down by securing and limiting the tie rod 150 to the corner post 122.
