Description

Technical Field

[0001] The embodiments of this utility model relate to the field of container equipment technology, specifically to a side-tilting container. Background Technology

[0002] With the rapid development of the logistics industry, containers have become a commonly used cargo transportation tool in modern logistics, and the application of containers is becoming more and more diversified, such as portable houses made from containers.

[0003] In existing technologies, wing-type containers rely on an extension mechanism to unfold the side panels as a whole, enabling side loading and unloading of goods and expanding the operating range of the wing-type container. This makes them ideal for transporting large instruments and heavy bulk cargo. Besides facilitating loading and unloading, the unfolded side panels can also provide sunshade and rain protection, realizing the multi-functional application of components. The unfolding side panels of wing-type containers generally fall into two categories. The first type involves the side panel and a portion of the top panel being fixed together and unfolding simultaneously. This method allows for a larger unfolding angle, but the unfolded side panel is concentrated in the upper space of the top panel, resulting in a smaller arm span extending beyond the container. This method is primarily suitable for cargo loading and transportation, limiting its application scope. The second type involves simple side panel unfolding. This unfolding method has a limited, generally smaller, unfolding angle, and its arm span is limited by the size of the side panel, resulting in a smaller usable range. Therefore, improvements and optimizations to existing technologies are needed. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a side-folding container, which solves the problem of small arm span of the side panel of the wing-type container in the related art.

[0005] According to one aspect, at least one embodiment of the present invention provides a side-tilting container, comprising:

[0006] main box;

[0007] The side extension body is rotatably mounted on the side of the main housing;

[0008] The two-section extension body is rotatably mounted on the side extension body and located at the end of the side extension body away from the main body;

[0009] Both the side extension body and the two-section extension body have two states: unfolded and retracted.

[0010] For example, in at least one embodiment of the present invention, a side-tilting container further includes a side-expansion drive transmission unit, the side-expansion drive transmission unit comprising:

[0011] The swing arm is oscillatingly positioned within the main housing cavity;

[0012] Side extension support one, one end of which is hinged to the swing arm, and the other end of which is hinged to the side extension body;

[0013] After the swing arm swings, the side extension body is in the extended state, and the side extension support is configured such that the hinge point with the swing arm is located outside the main housing cavity.

[0014] For example, in a side-tilting container provided in at least one embodiment of the present invention, the side-expansion support is a linear drive component.

[0015] For example, in at least one embodiment of the present invention, a side-tilting container includes a side-expansion drive transmission unit that further comprises:

[0016] Side support component two is a linear drive component, with one end hinged to the main housing and the other end hinged to the swing arm;

[0017] Along the swing direction of the swing arm, the first side extension support and the second side extension support are located on both sides of the swing arm.

[0018] For example, in at least one embodiment of the present invention, a side-tilting container is provided, wherein a hinge support one is provided at the end of the side extension body away from the hinge point between the side extension body and the main body, and a hinge support two is provided on the second extension body, which is hinged to the hinge support one. The container also includes a second extension drive transmission unit, which includes:

[0019] A sliding block is slidably mounted on the side extension body;

[0020] One end of the connecting rod is hinged to the slide block;

[0021] Connecting rod two, one end of which is hinged to the two extended sections;

[0022] The second support component is a linear drive component, with one end hinged to the side extension body;

[0023] The other ends of the first connecting rod, the other end of the second connecting rod, and the other ends of the two extension supports are connected by a common hinge point.

[0024] For example, in a side-tilting container provided by at least one embodiment of the present invention, the first hinged support, the second hinged support, and the second-section drive transmission unit constitute a transmission group, and the number of transmission groups is several and they are distributed at intervals between the side-section body and the second-section body.

[0025] For example, in a side-flip container provided by at least one embodiment of the present invention, the number of the side extension body and the two-section extension body are the same and there are two of each. The two side extension bodies and the two two-section extension bodies are respectively distributed on the left and right sides of the main container body.

[0026] For example, in at least one embodiment of the present invention, a side-tilting container further includes an insurance unit, the insurance unit comprising:

[0027] Locking pins are installed at the front and rear ends of the side extension body;

[0028] The locking rod is slidably mounted on the outer surface of the main housing.

[0029] The latch is hinged to the locking rod and has a locking groove that mates with the locking pin;

[0030] When the side extension body is in a retracted state, the locking groove is configured to snap onto the locking pin.

[0031] For example, in a side-tilting container provided in at least one embodiment of this utility model, the safety unit further includes:

[0032] An elastic element is sleeved on the locking rod. The two ends of the elastic element act on the locking rod and the main housing respectively. The elastic element is used to provide the locking buckle with a force that moves away from the side extension body.

[0033] For example, in at least one embodiment of the present invention, a side-tilting container is provided, wherein the number of insurance units is several.

[0034] The beneficial effects of the embodiments of this utility model are as follows:

[0035] In this invention, the main body provides basic load-bearing space for goods, and the side extension is connected to the side of the main body via a rotating connection structure to realize the opening and closing function of the side. The second-section extension is connected to the inner side of the side extension via a rotating connection structure to form a two-stage unfolding structure. When it is necessary to expand the side working range, the side extension first flips outward from the folded state to the unfolded state, at which point the outer edge of the side extension extends beyond the side of the main body; the second-section extension then flips outward from the folded state to the unfolded state away from the main body, and its outer edge further extends beyond the outer edge of the side extension. Through the superposition effect of the two-stage unfolding, the arm reach of the side panel is significantly increased. Compared to existing technologies where side panels can only unfold in a single stage or in conjunction with the top panel, the tiered rotation design of the side and second-stage unfolding bodies overcomes the arm span limitations of single-stage unfolding structures. The side panel unfolding solves the problem of small unfolding angles inherent in traditional simple side panels, while the second-stage unfolding body addresses the issue of concentrated arm span in the upper space when the side panel and top panel unfold in conjunction. Both achieve tiered movement through independent rotational connection structures, allowing the side panel's unfolding path to cover both the vertical and horizontal directions of the main container side, creating a wider operating area. In the folded state, the side and second-stage unfolding bodies fit against the sides of the main container and the inner sides of the side panels, respectively, maintaining the container's overall compactness and not occupying additional transport space. In the unfolded state, the linkage of the two stages expands the side coverage, meeting the needs of loading and unloading large cargo and providing a larger support area for multi-functional applications such as sunshade and rain protection, effectively solving the problem of small arm span for existing wing-type container side panel unfolding.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0044] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0048] 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.

[0049] like Figures 1-5 As shown, this invention illustrates a side-folding container according to one embodiment. The side-folding container includes a main body 1, a side-folding body 2, and two-section folding bodies 3. The main body 1 is a cuboid structure, with side mounting areas formed on its left and right sides. The main body 1 mainly includes a bottom, two uprights on the bottom plate, and a top plate on the upper part of the uprights. The side-folding body 2 is a plate-shaped component, one side of which is rotatably connected to the side mounting area of ​​the main body 1 via a rotating connection structure (such as a hinge or a pivot). This allows the side-folding body 2 to open and close around the axis of the rotating connection structure on the side of the main body 1, forming an unfolded state and a stowed state. In the stowed state, the plate surface of the side-folding body 2 is flush with the side of the main body 1. In the unfolded state, the side-folding body 2 flips outward around the rotation axis, and the plate surface forms an angle with the side of the main body 1.

[0050] The second-section extendable body 3 is a plate-shaped component. One side of it is rotatably connected to the inner side of the side extendable body 2 (i.e., the side panel of the side extendable body 2 closest to the main body 1) via a rotatable connection structure (such as a pivot or pin). The axis of the rotatable connection structure is parallel to the rotation axes of the side extendable body 2 and the main body 1. The second-section extendable body 3 has an unfolded state and a retracted state: in the retracted state, the panel of the second-section extendable body 3 is in contact with the inner side of the side extendable body 2; in the unfolded state, the second-section extendable body 3 flips outward around its rotation axis with the side extendable body 2, and the panel of the second-section extendable body 3 forms an angle with the panel of the side extendable body 2.

[0051] The main container 1 provides basic load-bearing space for goods. The side extension 2 is connected to the side of the main container 1 via a rotating connection structure, enabling the side to open and close. The second-stage extension 3 is connected to the inner side of the side extension 2 via a rotating connection structure, forming a two-stage unfolding structure. When it is necessary to expand the side working range, the side extension 2 first flips outward from the retracted state to the unfolded state, at which point the outer edge of the side extension 2 extends beyond the side of the main container 1. The second-stage extension 3 then flips outward from the retracted state to the unfolded state in a direction away from the main container 1, and its outer edge further extends beyond the outer edge of the side extension 2. Through the superposition effect of the two-stage unfolding, the arm reach of the side panel is significantly increased. Compared to existing technologies where side panels can only unfold in a single stage or in conjunction with the top panel, the tiered rotation design of side panel 2 and second-section panel 3 overcomes the arm span limitations of a single unfolding structure. The unfolding of side panel 2 solves the problem of a small unfolding angle in traditional simple side panels, while the unfolding of second-section panel 3 solves the problem of arm span being concentrated in the upper space when the side panel and top panel unfold in conjunction. The two sections achieve tiered movement through an independent rotating connection structure, allowing the side panel's unfolding path to cover both the vertical and horizontal directions of the main container 1's side, creating a wider operating area. In the stowed state, side panel 2 and second-section panel 3 fit against the side of the main container 1 and the inner side of side panel 2, respectively, maintaining the overall compactness of the container and not occupying additional transport space. In the unfolded state, the linkage of the two panels expands the side coverage area, meeting the needs of loading and unloading large cargo and providing a larger support area for multi-functional applications such as sunshade and rain protection, effectively solving the problem of small arm span range for existing wing-type container side panel unfolding.

[0052] At the same time, such as Figure 5 As shown, two side-folding containers are symmetrically placed in one area. The two containers have side extensions 2 and two-section extensions 3 that unfold from the sides. The ends of the two two-section extensions 3 that are away from the side extensions 2 can be connected or overlapped together. A canopy-like space is formed under the two side extensions 2 and the two two-section extensions 3 to facilitate other operations.

[0053] In some examples, the structure of the side-tipping container is optimized, for example, such as Figures 1-3 As shown, the side-extension drive transmission unit 4 of the side-tilting container includes a swing arm 41 and a side-extension support 42. A swing fulcrum is provided inside the cavity of the main container 1 (i.e., the interlayer area between the side wall of the main container 1 and the internal cargo space). The swing arm 41 is a rod-shaped component, with its middle part rotatably connected to the swing fulcrum via a pin, forming a structure that can swing planarly within the cavity around the pin. The side-extension support 42 is a straight rod-shaped component, one end of which is hinged to one end of the swing arm 41 via a pin (denoted as hinge point A), and the other end is hinged to the inner surface of the side-extension body 2 (i.e., the panel surface of the side-extension body 2 near the main container 1) via a pin (denoted as hinge point B).

[0054] When the side extension body 2 needs to be unfolded, the swing arm 41 swings around the swing fulcrum in a direction away from the center of the main housing 1, and pushes the side extension body 2 to flip outward around its rotation axis with the main housing 1 through the side extension support 42; as the swing arm 41 continues to swing, the hinge point A gradually moves from the inner side of the main housing 1 chamber (i.e. the side closer to the center of the main housing 1) to the outer side (i.e. the side closer to the side wall of the main housing 1). When the side extension body 2 reaches the unfolded state, the hinge point A is completely located outside the main housing 1 chamber (i.e. outside the outer surface of the side wall of the main housing 1).

[0055] The swing arm 41, oscillating within the main container 1, utilizes the available space within the chamber, avoiding interference with the cargo space inside the main container 1 and maintaining the container's loading capacity. The side extension support 42, hinged at both ends to the swing arm 41 and the side extension body 2 respectively, converts the swing motion of the swing arm 41 into the flipping motion of the side extension body 2, transmitting power through changes in the hinge point's position. When the side extension body 2 is deployed, the hinge point between the side extension support 42 and the swing arm 41 is located outside the main container 1 chamber. This structure allows the side extension support 42 to provide a greater outward thrust to the side extension body 2 in the deployed state: the swing amplitude of the swing arm 41 within the chamber is amplified by the side extension support 42 into the flipping angle of the side extension body 2. With the hinge point shifted outward, the effective working length of the side extension support 42 increases, thereby expanding the deployment range of the side extension body 2. Compared to the extension mechanism of traditional wing-type containers, this design overcomes the stroke limitation of a single linkage drive by adjusting the swing arm 41 and the hinge point position of the side extension support 42. This significantly increases the deployment angle and reach of the side extension body 2, effectively solving the problem of limited reach in existing technologies. Simultaneously, the hinge structure between the swing arm 41 and the side extension support 42 allows for automatic adjustment of angular deviations during movement, ensuring the smoothness of the side extension body 2's deployment.

[0056] In some examples, the structure of the side-tipping container is optimized, for example, such as Figures 1-3 As shown, the side-launch support 42 of the side-tilting container is a linear drive structure, consisting of an outer tube and an inner rod. The outer tube is a hollow tubular component with one open end, and the inner rod is a rod-shaped component that can slide along the axis of the outer tube. One end of the inner rod is inserted into the open end of the outer tube, and the other end is hinged to the side-launching body 2 (hinge point B). The other end of the outer tube is hinged to the swing arm 41 (hinge point A). The inner wall of the outer tube and the outer surface of the inner rod form a sliding fit, allowing the inner rod to extend and retract along the axial direction within the outer tube, thereby changing the overall length of the side-launch support 42. For example, the side-launch support 42 can be a hydraulic cylinder or electric cylinder that can achieve linear drive in the prior art.

[0057] When the swing arm 41 swings outward around the swing fulcrum inside the main housing 1, the hinge point A moves towards the side wall of the main housing 1 along with the swing arm 41. At this time, the inner rod slides outward inside the outer tube, the length of the side extension support 42 increases, and pushes the side extension body 2 to flip outward around its rotation axis with the main housing 1. When the swing arm 41 swings inward, the inner rod slides inward inside the outer tube, the length of the side extension support 42 shortens, and pulls the side extension body 2 back to fit against the side of the main housing 1, thus realizing the storage of the side extension body 2.

[0058] The linear drive of the side extension support 42, through the sliding engagement of the outer tube and the inner rod, allows its length to automatically adjust as the distance between hinge points A and B changes during the swing of the swing arm 41, avoiding motion interference caused by the fixed length of the rigid connecting rod. When the swing arm 41 swings, the variable-length side extension support 42 can dynamically compensate for the displacement difference between the swing trajectory of the swing arm 41 and the flipping trajectory of the side extension body 2, so that the unfolding angle and stroke of the side extension body 2 are no longer limited by the fixed swing amplitude of the swing arm 41, thereby expanding the maximum unfolding angle of the side extension body 2. The length variation of the side extension support 42 allows the swing arm 41 to drive the side extension body 2 to achieve a larger flipping range with a smaller swing amplitude in the cavity, effectively improving the space utilization of the side extension drive transmission unit 4. In addition, the adjustable length design allows the tensile or compressive stress borne by the side extension support 42 during movement to be evenly distributed through the sliding of the outer tube and the inner rod, reducing local stress concentration at the hinge point, reducing the risk of component wear, and extending the service life of the drive unit.

[0059] In some examples, the structure of the side-tipping container is optimized, for example, such as Figures 1-3 As shown, the side-expansion drive transmission unit 4 of the side-tilting container also includes a second side-expansion support 43, which is a linear drive component consisting of an outer tube and an inner rod. The outer tube is a hollow tubular component with one end open, and its other end is hinged to the side wall of the main container 1 via a pin (denoted as hinge point C). The inner rod is a rod-shaped component that can slide along the axis of the outer tube, with one end inserted into the open end of the outer tube and the other end hinged to the middle area of ​​the swing arm 41 via a pin (denoted as hinge point D). The inner wall of the outer tube and the outer surface of the inner rod form a sliding fit, allowing the inner rod to extend and retract along the axial direction within the outer tube. Along the swing direction of the swing arm 41 (i.e., the tangential direction of the circumference of the swing arm 41 rotating around the swing fulcrum), the first side extension support 42 and the second side extension support 43 are located on both sides of the swing arm 41: the hinge point A of the first side extension support 42 (the hinge end with the swing arm 41) is located at one end of the swing arm 41, and the hinge point D of the second side extension support 43 is located in the middle of the swing arm 41. When the swing arm 41 swings to one side around the swing fulcrum, the first side extension support 42 is stretched or compressed to drive the side extension body 2 to unfold, while the second side extension support 43 provides a reverse support force to the swing arm 41 through its telescopic movement. For example, the second side extension support 43 can be a hydraulic cylinder or electric cylinder that can achieve linear drive in the prior art.

[0060] The adjustable length of the second side extension support 43, together with the first side extension support 42, forms a dual-drive support layout. Distributed on both sides along the swing direction of the swing arm 41, this design ensures that the swing arm 41 experiences bidirectional pushing and pulling forces during swinging. This effectively balances the torque generated by unilateral force on the swing arm 41, preventing it from tilting or jamming and improving the stability of the drive transmission unit. The adjustable length of the second side extension support 43, through the sliding cooperation between the outer tube and the inner rod, dynamically adapts to the change in distance between hinge points C and D during the swing of the swing arm 41. Working in conjunction with the first side extension support 42, it expands the effective swing amplitude of the swing arm 41: when the first side extension support 42 pushes the side extension body 2 outward, the second side extension support 43 synchronously extends and retracts to maintain the torque balance of the swing arm 41, allowing the swing arm 41 to swing at a larger angle, thereby driving the side extension body 2 to achieve a larger unfolding angle. Compared with the traditional single-sided drive method, this dual-sided adjustable length drive structure significantly improves the motion stability and structural reliability of the side extension body 2 during its deployment. At the same time, it amplifies the driving effect of the swing arm 41 through bidirectional force transmission, further increasing the arm span range of the side extension body 2, and effectively solving the problems of insufficient stability and limited arm span in the existing side plate deployment drive mechanism.

[0061] In some examples, the structure of the side-tipping container is optimized, for example, such as Figures 1-3As shown, in a side-tilting container, a hinge support 51 is provided at the end of the side extension 2 away from its hinge point with the main container 1 (i.e., the free end of the side extension 2). This hinge support 51 is a long arm structure provided on the surface of the side extension 2, and has a hinge hole. A hinge support 52 is provided at the corresponding position of the second extension 3. The second hinge support 52 is a long arm structure provided on the surface of the second extension 3, and has a hinge hole aligned with the hinge hole. The two are hinged together by a pin, allowing the second extension 3 to rotate relative to the side extension 2 around the pin. The second extension drive transmission unit 53 includes a slide 531, a connecting rod 532, a connecting rod 533, and a second extension support 534. The slide block 531 is a block-shaped component with a groove at its bottom parallel to the surface of the side extension body 2. The groove extends in the same direction as the width (when unfolded) or height (when folded) of the side extension body 2. The slide block 531 is slidably mounted on the inner side of the side extension body 2 (i.e., the surface of the side extension body 2 near the main housing 1) via the groove. The first connecting rod 532 is a rod-shaped component. One end of it is hinged to the top of the slide block 531 via a pin (referred to as hinge point E), and the other end is hinged to the common hinge point (referred to as hinge point F) of the second extension support 534 and the second connecting rod 533. The second connecting rod 533 is a rod-shaped component. One end of it is hinged to the inner side of the second extension body 3 (i.e., the surface of the second extension body 3 near the side extension body 2) via a pin (referred to as hinge point G), and the other end is hinged to hinge point F. The second-section support 534 is a linear drive component, consisting of an outer tube and an inner rod. One end of the outer tube is hinged to the outer surface of the side extension body 2 via a pin (denoted as hinge point H). The inner rod can slide along the axis of the outer tube, and its other end is hinged to hinge point F. When the inner rod of the second-section support 534 extends or retracts within the outer tube, it drives hinge point F to move. This, through connecting rod 532, pulls the slide block 531 to slide along the slide groove of the side extension body 2. Simultaneously, through connecting rod 533, it pushes the second-section extension body 3 to rotate around the hinge pin connecting it to the side extension body 2, thus realizing the unfolding or retraction of the second-section extension body 3.

[0062] The hinged connection between hinged support 51 and hinged support 52 provides a pivot point for the two-section extended body 3, allowing it to move independently relative to the side extended body 2. The sliding structure of the slide 531 along the side extended body 2 converts the telescopic motion of the two-section extended support 534 into linear sliding. Through the hinged transmission of connecting rod 532 and connecting rod 533, the linear motion is converted into the flipping motion of the two-section extended body 3. The length-adjustable two-section extended support 534 dynamically adjusts its length through the sliding cooperation between the outer tube and the inner rod to adapt to changes in the distance between the slide 531 and the two-section extended body 3, ensuring effective force transmission during the transmission process. The shared hinge point F design creates a stable triangular structure by forming the motion trajectories of connecting rod 532, connecting rod 533, and the second extension support 534. When the second extension support 534 extends or retracts, the sliding of the slide block 531 and the flipping of the second extension body 3 occur synchronously: when the slide block 531 slides towards the free end of the second extension body 2, connecting rod 533 pushes the second extension body 3 to flip outwards and unfold; when the slide block 531 slides towards the hinge end of the second extension body 2, connecting rod 533 pulls the second extension body 3 to flip inwards and retract. This transmission structure, through three-stage linkage (extension or retraction of the second extension support 534 → sliding of the slide block 531 → connecting rod transmission → flipping of the second extension body 3), breaks through the angle limitation of traditional single-stage linkage drive, allowing the unfolding angle of the second extension body 3 to be flexibly adjusted by the stroke of the slide block 531 and the extension or retraction of the second extension support 534, significantly increasing the arm span range of the second extension body 3. Meanwhile, the sliding block 531 and the sliding groove of the side extension body 2 cooperate to ensure the stability of the motion trajectory, avoid deviation or jamming during the deployment of the second-stage extension body 3, improve the reliability and coordination of the second-stage deployment mechanism, and effectively solve the problems of low transmission efficiency and limited deployment range of multi-stage deployment structures in the prior art.

[0063] In some examples, the structure of the side-tipping container is optimized, for example, such as Figures 1-3 As shown, in the side-tilting container, hinged support 1 51, hinged support 2 52, and the second-stage unfolding drive transmission unit 53 together constitute a transmission group 5. Multiple hinged supports 1 51 are evenly spaced along the length direction of the inner side of the side-tilting body 2 (i.e., the extension direction of the hinge axis between the side-tilting body 2 and the main body 1). Each hinged support 1 51 corresponds to a hinged support 2 52 on the inner side of the second-stage unfolding body 3, and the two are hinged together by a pin. At the hinge position of each hinged support 1 51 and hinged support 2 52, a second-stage unfolding drive transmission unit 53 (including a slide 531, connecting rod 1 532, connecting rod 2 533, and second-stage unfolding support 534) is provided on the outer side of the side-tilting body 2, forming multiple transmission groups 5 with identical structures. Each transmission group 5 is spaced apart along the length direction of the side-tilting body 2 and the second-stage unfolding body 3. In this example, the preferred number of transmission groups 5 is two, which reduces the number of components on the container while ensuring smooth unfolding of the second stage.

[0064] In each transmission group 5, the sliding groove of the slide block 531 extends in the same direction as the width (when unfolded) or height (when folded) of the side extension body 2. The hinge points H of the two extension supports 534 (hinged with the side extension body 2) are spaced apart along the length of the outer side of the side extension body 2. When the inner rod of the two extension supports 534 extends or retracts in the outer tube, the slide blocks 531 of all transmission groups 5 slide synchronously along their respective sliding grooves. Through the hinge transmission of connecting rod one 532 and connecting rod two 533, the corresponding two extension bodies 3 are pushed to rotate synchronously around the pins of the hinge support one 51 and the hinge support two 52, so as to realize the overall unfolding or folding of the two extension bodies 3.

[0065] The structure of multiple transmission groups 5 spaced apart along the length of the side extension body 2 and the second-stage extension body 3 ensures that each position of the second-stage extension body 3 is subjected to independent and synchronous driving force, avoiding the torsion deformation or local jamming problems of the second-stage extension body 3 caused by unilateral force when driven by a traditional single transmission group 5. The second-stage extension drive transmission units 53 of each transmission group 5 have the same structure and are spaced and aligned, ensuring that the sliding stroke of the slide 531 and the extension amount of the second-stage support 534 are consistent at all positions, keeping the unfolding angle of the second-stage extension body 3 uniform throughout its length, and improving the consistency and smoothness of the second-stage unfolding action. The spaced transmission groups 5 distribute the driving force to multiple points of application, reducing the stress intensity of a single transmission group 5, reducing wear or fatigue damage to components caused by concentrated force, and extending the service life of the second-stage extension drive transmission unit 53. Meanwhile, the transmission group 5 covers the entire length range of the side extension body 2 and the second-stage extension body 3, ensuring that there are no undriven areas during the deployment process. This solves the problem of insufficient local deployment caused by the lack of drive points in traditional multi-stage deployment structures and further expands the effective arm span range of the second-stage extension body 3.

[0066] In some examples, the structure of the side-tipping container is optimized, for example, such as Figures 1-3 As shown, the main body 1 of the side-tilting container is a cuboid structure, with its left and right sides forming side mounting areas. A side extension body 2 is rotatably connected to each of the left and right sides, and each side extension body 2 can be flipped outwards around its respective axis of rotation. A two-section extension body 3 is rotatably connected to the inner side of each side extension body 2, and each two-section extension body 3 can be flipped away from the main body 1 around its respective axis of rotation.

[0067] The symmetrical structure of two side-mounted units 2 and two two-sectioned units 3, distributed on the left and right sides of the main container 1, enables the container to be deployed in stages on both sides. The left-side side-mounted unit 2 and the two-sectioned unit 3, as well as the right-side unit and the two-sectioned unit 3, form independent two-stage deployment units. These units can operate synchronously or independently: when deployed synchronously, the side-mounted units 2 and the two-sectioned units 3 on both sides together expand the working area on both sides of the container, creating symmetrical loading and unloading spaces and shaded / rain-proof areas; when deployed independently, only one side unit can be deployed according to actual needs, improving operational flexibility. This symmetrical layout on both sides ensures a more balanced distribution of the container's center of gravity when deployed, avoiding tilting or instability issues caused by unilateral force during single-side deployment, thus improving operational safety. Compared with the existing technology of only one side unfolding structure, the side extension body 2 and the two-section extension body 3 set on both sides significantly increase the overall arm span coverage of the container through the hierarchical unfolding and superposition of the left and right sides. This effectively solves the problem of small arm span range of traditional wing-type container side panel unfolding, and at the same time expands the multi-functional application scenarios of the container (such as both sides serving as temporary sunshades or working platforms at the same time).

[0068] In some examples, the structure of the side-tipping container is optimized, for example, such as Figures 1-4 As shown, the safety unit 6 of the side-folding container includes a locking pin 61, a locking rod 62, and a locking buckle 63. The locking pin 61 is a columnar member, vertically fixed to the front and rear ends of the side-folding body 2, with its axis parallel to the rotation axis of the side-folding body 2. The locking rod 62 is a rod-shaped member with a sliding channel on the outer surface of the main container 1. The locking buckle 63 is a plate-shaped member, one end of which is hinged to the end of the locking rod 62 near the side-folding body 2 via a pin, forming a structure that can rotate around the pin. The other end of the locking buckle 63 has a locking groove 631, which is an arc-shaped or U-shaped groove adapted to the shape of the locking pin 61. When the side-folding body 2 is in the retracted state, the plate surface of the side-folding body 2 is in contact with the side of the main container 1, the locking pin 61 is aligned with the locking groove 631 of the locking buckle 63, and by rotating the locking buckle 63, the locking groove 631 is locked onto the locking pin 61, thereby locking the side-folding body 2 to the main container 1.

[0069] The locking mechanism of the locking pin 61 and the locking groove 631 of the latch 63 forms a mechanical lock when the side extension 2 is in the retracted state, preventing the side extension 2 from accidentally unfolding due to vibration or external force during transportation, thus improving the safety and reliability of container transportation. The locking rod 62 is slidably mounted on the main body 1, allowing the locking and unlocking of the latch 63 to be achieved by sliding the locking rod 62: when locking, sliding the locking rod 62 aligns the latch 63 with the locking pin 61, and rotating the latch 63 engages it; when unlocking, sliding the locking rod 62 in the opposite direction and rotating the latch 63 disengages it from the locking pin 61, making operation convenient. The hinged design of the latch 63 to the locking rod 62 allows the locking groove 631 to automatically adjust its angle according to the position of the locking pin 61, compensating for positional deviations caused by assembly errors when the side extension 2 is retracted, ensuring the stability of the locking mechanism. Compared with existing locking methods that rely on a single bolt or hook, this safety unit 6 forms a more reliable mechanical locking structure through the linkage of the locking pin 61, locking rod 62 and locking buckle 63. This effectively solves the problem of insecure locking when the wing-shaped container side panel is folded up, and at the same time, it makes it easier for operators to quickly complete locking and unlocking operations, thus improving ease of use.

[0070] In some examples, the structure of the side-tipping container is optimized, for example, such as Figures 1-4 As shown, the safety unit 6 of the side-tilting container also includes an elastic element 64, which is a helical spring with an inner diameter that matches the outer diameter of the locking rod 62. A limiting boss is provided at the end of the locking rod 62 away from the latch 63. A support frame is provided on the outer surface of the main container 1, and the locking rod 62 is slidably mounted on the support frame. The elastic element 64 is sleeved on the locking rod 62, with one end abutting against the limiting boss and the other end abutting against the support frame, forming an elastic support structure that acts on the main container 1 and the locking rod 62 respectively. The elastic element 64 is always in a compressed state, providing a force pointing away from the side extension body 2, ensuring the latching state between the locking pin 61 and the locking groove 631.

[0071] The structure of the elastic element 64 sleeved on the locking rod 62, through the cooperation of the limiting boss and the support frame, ensures that the latch 63 remains separated from the side extension body 2 in the unlocked state, avoiding jamming caused by the latch 63 accidentally contacting the locking post 61. When the side extension body 2 is in the retracted state and needs to be locked, the operator needs to overcome the elastic force of the elastic element 64 to slide the locking rod 62 closer to the side extension body 2 and rotate the latch 63, so that the locking groove 631 is engaged with the locking post 61. At this time, the compressed state of the elastic element 64 provides pre-tightening force to the locking structure, compensating for displacement caused by vibration during transportation and preventing the fit between the latch 63 and the locking post 61 from loosening. When unlocking, the elastic force of the elastic element 64 needs to be overcome to slide the locking rod 62 towards the side extension body 2 and rotate the latch 63, causing the latch 63 to disengage from the locking pin 61. The setting of the elastic element 64 forms an elastic buffer mechanism, which not only enhances the reliability of the locked state, but also avoids the wear of components that may be caused by rigid connection. At the same time, the elastic force assists to improve the comfort of operation, effectively solving the problem of unlocking difficulty or locking failure caused by external force vibration in traditional locking mechanisms.

[0072] In some examples, the structure of the side-tipping container is optimized, for example, such as Figures 1-4 As shown, the side-folding container has two safety units 6, referred to as the first safety unit 6 and the second safety unit 6. The two safety units 6 are located at the front and rear ends of the side extension 2, respectively. Through the cooperation of the two safety units 6, a double-point locking is achieved when the side extension 2 is in the folded state, improving the overall stability.

[0073] Two locking units 6 are respectively located at the front and rear ends of the side extension 2, distributing the locking force to two points of application. This avoids the problem of partial deformation or locking failure of the side extension 2 due to unilateral force on a single locking unit 6. The structure in which the latches 63 of the dual locking units 6 simultaneously engage with the corresponding locking pins 61, through coordinated locking at both the front and rear points, significantly improves the connection rigidity between the side extension 2 and the main container 1, effectively resisting vibrations or impacts during transportation and preventing the side extension 2 from accidentally unfolding due to loosening at a single point of force. The elastic element 64 ensures the long-term stability of the locked state in the two locking units 6. Compared with a single locking unit 6, the dual locking units 6 enhance the reliability of the locking mechanism through redundant design. Even if one locking unit 6 fails unexpectedly, the other can still maintain basic locking function, further improving the safety during container transportation.
