Patent Description:
The conventional storage box structure commonly includes a box body and a box cover that are combinable. Due to the fixed structure of the box body, it may not be folded, which takes up a lot of space and causes inconvenience in collection, transportation, and use. The application of storage cabinets is extremely widespread, and they may be found in almost every office or household setting, both domestically and internationally. Currently, the design of storage cabinets is mainly based on separate designs according to the different requirements of users and environments, with almost no universal storage cabinet available. Therefore, storage cabinets have significant specificity (e.g., student storage cabinets, household clothing storage cabinets, refrigerated storage cabinets, etc.) and limitations, and are only suitable for specific locations. However, as the demand for living space increases, relying solely on large storage cabinets is no longer sufficient to meet the needs of daily life. As a result, convenient small storage cabinets have emerged (e.g., small children's storage cabinets, plastic small storage cabinets, etc.). Furthermore, in many supermarkets and entertainment venues, automated storage cabinets have been designed to facilitate customer access to belongings. Although these designs meet usage requirements in certain environments, these storage cabinets still require a significant amount of space when not in use, especially in environments with limited space (e.g., households), where the issue of space occupation becomes more prominent.

The folding storage cabinet <NUM> includes a back plate <NUM>, which is formed with at least one bottom pivot part <NUM> at the bottom portion and at least one top pivot part <NUM> at the top portion. At least one back plate pivot part <NUM> is arranged on both sides between the top portion and the bottom portion respectively. Two folding side plates <NUM> are foldable in a flat manner. One side of the folding side plate <NUM> is formed with at least one first side plate pivot part <NUM>, while the other side is formed with at least one second side plate pivot part <NUM>. The first side plate pivot part <NUM> of the folding side plates <NUM> correspondingly pivotally connected to the back plate pivot part <NUM> of the back plate <NUM>. In one implementation, the folding side plate <NUM> are composed of a first side plate <NUM> and a second side plate <NUM>. At least one first side plate pivot part <NUM> is formed on one side of the first side plate <NUM>, while the other side of the first side plate <NUM> is formed with at least one third side plate pivot part <NUM>. At least one second side plate pivot part <NUM> is formed on one side of the second side plate <NUM>, and the second side plate <NUM> is formed with at least one fourth side plate pivot part <NUM> on the corresponding side of the third side plate pivot part <NUM>. The third side plate pivot part <NUM> correspondingly pivotally connected to the fourth side plate pivot part <NUM>, allowing the first side plate <NUM> and the second side plate <NUM> are foldable in a flat manner. The folding storage cabinet <NUM> also includes a frame <NUM>, the selected part of the dotted circle is a schematic diagram of another angle of the frame <NUM>. At least one fixed groove <NUM> on the top surface of the frame <NUM> and at least one fixed rod <NUM> on the bottom surface of the frame <NUM>. At least one first frame pivot part <NUM> is formed on each side of the frame <NUM> facing the two folding side plates <NUM>. The first frame pivot part <NUM> movably pivots to the second side plate pivot part <NUM> of the folding side plates <NUM>. A bottom plate <NUM>, which has at least one bottom plate pivot part <NUM> on one side of the bottom plate <NUM>. The bottom plate <NUM> may be movably pivoted to the bottom pivot part <NUM> of the back plate <NUM> through the bottom plate pivot part <NUM>, so that the bottom plate <NUM> may be folded relative to the back plate <NUM>. Additionally, a top plate <NUM> includes a cover plate <NUM> with at least one first cover plate pivot part <NUM> on one side of the top plate <NUM> and the other two opposite sides of the top plate <NUM> are each formed with at least one second cover plate pivot part <NUM>. The first cover plate pivot part <NUM> pivotally connected to the top pivot part <NUM> of the back plate <NUM>, allowing the cover plate <NUM> to be opened and folded relative to the back plate <NUM>. Two wing plates <NUM> are each formed with at least one wing plate pivot part <NUM> corresponding to one side of the two second cover plate pivot parts <NUM> of the cover plate <NUM>, the wing plate pivot part <NUM> is correspondingly pivoted to the second cover plate pivot part <NUM>, such that the wing plates <NUM> to be opened and closed relative to the cover plate. In one implementation, the folding storage cabinet <NUM> further includes a door plate <NUM>, which has at least one door plate pivot part <NUM> on one side of the door plate <NUM>. The frame <NUM> is formed with at least one second frame pivot part <NUM> on the side facing the door plate pivot part <NUM>, the door plate pivot part <NUM> is correspondingly pivoted to the second frame pivot part <NUM>, allowing the door plate <NUM> to be opened and closed relative to the frame <NUM>. The assembled configuration of the above components is shown in <FIG>. Furthermore, in one implementation, the bottom pivot part <NUM> and the top pivot part <NUM> may be formed on the frame <NUM> without being formed on the back plate <NUM>, or the bottom pivot part <NUM> may be formed on the back plate <NUM> while the top pivot part <NUM> is formed on the frame <NUM>, or the bottom pivot part <NUM> may be formed on the frame <NUM> while the top pivot part <NUM> is formed on the back plate <NUM>.

The bottom pivot part <NUM> may be formed at the bottom portion of one of the frame <NUM> and the back plate <NUM>, while the top pivot part <NUM> may be formed at the top portion of other one of the frame <NUM> and the back plate <NUM>. In one implementation, when the one of the frame <NUM> and the back plate <NUM> is the same as the other one of the frame <NUM> and the back plate <NUM>, the top pivot part <NUM> and the bottom pivot part <NUM> are both located in the same one of the frame <NUM> and the back plate <NUM>, meaning that the top pivot part <NUM> and the bottom pivot part <NUM> are simultaneously formed on the back plate <NUM> or the frame <NUM>. In another implementation, when the one of the frame <NUM> and the back plate <NUM> is different from the other one of the frame <NUM> and the back plate <NUM>, the top pivot part <NUM> is located in one of the frame <NUM> and the back plate <NUM>, while the bottom pivot part <NUM> is located in other one of the frame <NUM> and the back plate <NUM>. In other words, the bottom pivot part <NUM> may be formed on the back plate <NUM> while the top pivot part <NUM> is formed on the frame <NUM>, or the bottom pivot part <NUM> is formed on the frame body <NUM> while the top pivot part <NUM> is formed on the back plate <NUM>. The present disclosure is not limited to this. In one implementation, the first cover plate pivot part <NUM> of the cover plate <NUM> corresponds to the top pivot part <NUM>. Therefore, when the top pivot part <NUM> is set on the frame <NUM>, the first cover plate pivot part <NUM> of the cover plate <NUM> is oriented towards the top pivot part <NUM> of the frame <NUM>. In one implementation, the bottom plate pivot part <NUM> of the bottom plate <NUM> corresponds to the bottom pivot part <NUM>. Therefore, when the bottom pivot part <NUM> is set on the frame <NUM>, the bottom plate pivot part <NUM> of the bottom plate <NUM> is oriented towards the bottom pivot part <NUM> of the frame <NUM>.

In one implementation, the frame <NUM> and the back plate <NUM> may simultaneously have the bottom pivot part <NUM>, and the bottom plate pivot part <NUM> may be connected to either the frame <NUM> or the back plate <NUM> at the bottom pivot part <NUM>, and the folding direction of the bottom plate <NUM> is determined by the pivotally connecting object of the bottom plate pivot part <NUM>. In one implementation, the frame <NUM> and the back plate <NUM> may simultaneously have the top pivot part <NUM>, and the first cover plate pivot part <NUM> may be pivotally connected to either the frame <NUM> or the back plate <NUM> at the top pivot part <NUM>, and the folding direction of the cover plate <NUM> is determined by the pivotally connecting object of the first cover plate pivot part <NUM>.

<FIG> is a schematic diagram illustrating opening and closing of a top plate and a door plate of a folding storage cabinet according to another example implementation of the present disclosure. The inside of the folding storage cabinet <NUM> forms a storage space <NUM>. When the top plate <NUM> is opened relative to the back plate <NUM>, the user may place items into the storage space <NUM> on the bottom plate <NUM> from above the folding storage cabinet <NUM>. When the door plate <NUM> is opened relative to the frame <NUM>, the user may also place items into the storage space <NUM> on the bottom plate <NUM> from the front of the folding storage cabinet <NUM>. Meanwhile, it is also possible to simultaneously open the top plate <NUM> and the door plate <NUM> to retrieve or place items.

<FIG> is a schematic diagram illustrating folding of a top plate and a wing plate according to an example implementation of the present disclosure. With reference to <FIG> together. In one implementation, the two sides of the cover plate <NUM> of the top plate <NUM> are respectively pivotally connected to two wing plates <NUM>. The top plate <NUM> normally press against the two folding side plates <NUM> through the two wing plates <NUM>, resulting the top plate <NUM> is normally formed with a width H1 before the two wing plates <NUM> are folded. The wing plates <NUM> may be folded relative to the cover plate <NUM>, when the two wing plates <NUM> are folded towards the cover plate <NUM>, the top plate <NUM> forms a width H2. Comparing the width H1 with the width H2, it may be seen that the width H2 is obviously smaller than the width H1. Please refer to <FIG>, which is a schematic diagram illustrating the folding of the top plate according to another example implementation of the present disclosure. As described in <FIG>, when the folding storage cabinet <NUM> is to be folded for storage when not in use, the first step involves bending and folding the two wing plates <NUM> of the top plate <NUM> relative to the cover plate <NUM>, so that the top plate <NUM> forms the width H2. After the two wings <NUM> of the top plate <NUM> are folded, the whole top plate <NUM> may be folded relative to the back plate <NUM> and further overlapped with the back plate <NUM>, so that the top plate <NUM> may be folded inside the storage space <NUM>. Furthermore, please refer to <FIG>, which is a schematic diagram illustrating the folding of a bottom plate according to an example implementation of the present disclosure. As described in <FIG>, the bottom plate <NUM> is normally pivotally connected to the back plate <NUM> and both sides of the bottom plate <NUM> press against the two folding side plates <NUM>. Therefore, when the bottom plate <NUM> needs to be folded, the bottom of the bottom plate <NUM> may be exerted force to push the bottom plate <NUM> upward, so that the bottom plate <NUM> is folded relative to the back plate <NUM> and overlaps with the back plate <NUM>. Additionally, the folding actions of the top plate <NUM> and the bottom plate <NUM> is provided as the implementations and is not limited to the specific order shown in the figure. It is not necessary to fold the bottom plate <NUM> first and then fold the top plate <NUM> as shown in the figure, so that the top plate <NUM> covers the bottom plate <NUM>. Returning to <FIG>, the back plate <NUM> has a bottom surface A, an upper side surface B and a lower side surface C. The top pivot part <NUM> is located on the upper side surface B, and the bottom pivot part <NUM> is located on the lower side surface C. If the distance between the top pivot part <NUM> and the bottom surface A is greater than the distance between the bottom pivot part <NUM> and the bottom surface A, then when the top plate <NUM> and the bottom plate <NUM> are folded, it is necessary to fold the bottom plate <NUM> first, and then fold the top plate <NUM>, so that the top plate <NUM> and the bottom plate <NUM> may be sequentially folded into a space formed by the bottom surface A, the upper side surface B and the lower side surface C of the back plate <NUM>. If the distance between the top pivot part <NUM> and the bottom surface A is smaller than the distance between the bottom pivot part <NUM> and the bottom surface A, then when the top plate <NUM> and the bottom plate <NUM> are folded, it is necessary to fold the top plate <NUM> first, and then fold the bottom plate <NUM>. In order to sequentially fold the top plate <NUM> and the bottom plate <NUM> into a space formed by the bottom surface A, the upper side surface B and the lower side surface C of the back plate <NUM>. In order to fully fold the top plate <NUM> and the bottom plate <NUM> into the space of the back plate <NUM> without affecting the folding of the folding side plates <NUM>, the distance between the top pivot part <NUM> and the bottom surface A is not equal to the distance between the bottom pivot part <NUM> and the bottom surface A, and the difference between the two distances must be at least greater than a difference threshold. The threshold value may be the thickness of the last folded component of both the top plate <NUM> and the bottom plate <NUM>. For example, if the bottom plate <NUM> is folded first and then the top plate <NUM> is folded, the threshold value may be the thickness of the top plate <NUM> in the closed state of the wing plate <NUM>. If the top plate <NUM> is closed before the bottom plate <NUM> is closed, the difference threshold may be the thickness of the bottom plate <NUM>. In one implementation, when the top pivot part <NUM> and the bottom pivot part <NUM> are formed on the frame <NUM>, the frame <NUM> may also have a bottom surface, an upper side surface, and a lower side surface. The distance between the top pivot part <NUM> and the bottom surface of the frame <NUM>, and the distance between the bottom pivot part <NUM> and the bottom surface of the frame <NUM> are not the same, to avoid the top plate <NUM> and the bottom plate <NUM> interfering with the folding of the folding side plates <NUM>. In another implementation, if the height of the back plate <NUM> is greater than the sum of the lengths of the bottom plate <NUM> and the top plate <NUM>, that is, there is no overlap between the top plate <NUM> and the bottom plate <NUM> after folding, the distance between the top pivot part <NUM> and the bottom surface A may be equal to the distance between the bottom pivot part <NUM> and the bottom surface A.

<FIG> and <FIG> are the schematic diagrams illustrating the folding of the folding storage cabinet according to the example implementations of the present disclosure. With reference to <FIG>, after the top plate <NUM> and the bottom plate <NUM> (not shown) are folded, the top and bottom of the folding storage cabinet <NUM> are connected. Referring to <FIG>, the top plate <NUM> and the bottom plate <NUM> (not shown) of the folding storage cabinet <NUM> have been folded, and then the two folding side plates <NUM> are folded into a V-shape. Please refer to <FIG>, which shows another schematic diagram illustrating the folding of the folding storage cabinet in <FIG> according to the example implementation of the present disclosure. When the two folding side plates <NUM> are completely folded, the two folding side plates <NUM> may be folded into a flat manner, so that the overall volume of the folding storage cabinet <NUM> is greatly reduced, which is convenient for storage when not in use. In one implementation, one side of the back plate <NUM> is provided with a fastening piece <NUM>, and the side of the frame <NUM> adjacent to the fastening piece <NUM> is relatively formed with a relative fastening part <NUM>. When the two folding side plates <NUM> are bent into a flat manner, the fastening piece <NUM> may be fastened with the relative fastening part <NUM> to stably hold the folding storage cabinet <NUM>.

The following are the verification results of the bottom plate and laminate after reinforcement:.

Experiments were conducted on embodiment <NUM> and comparative embodiment <NUM> to test the compressive strength of the side plates in accordance with the present disclosure. A weight of <NUM> was applied to the bottom plate of embodiment <NUM> (referred to the bottom plate <NUM> of the present disclosure, hereinafter referred to as the bottom plate <NUM>) and the bottom plate <NUM> of comparative embodiment <NUM>, respectively. The analysis was performed using computer-aided engineering (CAE) simulation methods. The results are shown in <FIG> A representing embodiment <NUM> and <FIG> representing comparative embodiment <NUM>. Where the difference between the bottom plate <NUM> of comparative embodiment <NUM> and the bottom plate <NUM> of embodiment <NUM> is that the bottom plate <NUM> of comparative embodiment <NUM> does not include the integral reinforcing structure contained in the reinforcing structure <NUM> of the present disclosure.

Referring to Table <NUM>, the maximum deformation value of the bottom plate <NUM> in comparative embodiment <NUM> is <NUM> times higher than the bottom plate <NUM> in embodiment <NUM>. This indicates that in embodiment <NUM>, compared to comparative embodiment <NUM>, the maximum deformation value of the bottom plate <NUM> is reduced, so that the compression resistance is effectively improved.

The laminate of embodiment <NUM> of the present disclosure and comparative embodiment <NUM> were tested for compressive strength, and the laminate of embodiment <NUM> (referring to the laminate <NUM> of the present disclosure, hereinafter referred to as laminate <NUM>) and the laminate <NUM> of comparative embodiment <NUM> were respectively weighed with <NUM>, and then analyzed by CAE simulation calculation method. The results are shown in <FIG> A representing embodiment <NUM> and <FIG> representing comparative embodiment <NUM>. The difference between the laminate <NUM> of Comparative Example <NUM> and the laminate <NUM> of Embodiment <NUM> is that the laminate <NUM> does not include the integral reinforcing structure contained in the reinforcing structure <NUM> of the present disclosure.

Referring to Table <NUM>, the maximum deformation value of the laminate <NUM> in comparative embodiment <NUM> is <NUM> times greater than the laminate <NUM> in embodiment <NUM>. This indicates that in embodiment <NUM>, compared to comparative embodiment <NUM>, the maximum deformation value of the laminate <NUM> is reduced, so that the compression resistance is effectively improved.

Referring to <FIG> and <FIG>, illustrating the state before and after implementation of the folding storage cabinet according to an example implementation of the present disclosure. Two opposite sides of the bottom plate <NUM> each formed with at least one fixing part <NUM>, and the fixing part <NUM> may be formed into a hook-and-claw component, while at least one corresponding fixing part <NUM> is formed on one side of the first side plate <NUM> corresponding to the fixing parts <NUM> and another at least one corresponding fixing part <NUM> is formed on one side of the second side plate <NUM> corresponding to the fixing parts <NUM>. The corresponding fixing part <NUM> may be formed into a groove-shaped structure to fix the fixing part <NUM>, so that the bottom plate <NUM> may be fixed to the corresponding fixing part <NUM> through the fixing part <NUM> to provide a stable support when the bottom plate <NUM> is loaded with heavy objects.

Referring to <FIG> and <FIG> are the schematic diagrams illustrating a folding storage cabinet according to an example implementation of the present disclosure. The laminate <NUM> has at least one or more fixing tenons <NUM> on each opposite side. The frame <NUM> has a tenon fixing groove <NUM> formed at a position correspond to the fixing tenons <NUM>. When the laminate <NUM> is not in use, the laminate <NUM> may be fixed in the tenon fixing groove <NUM> through the fixing tenons <NUM>, so that the laminate <NUM> may be stored in an upright position correspond to the frame <NUM>. In one implementation, at least one of the fixed tenons <NUM> may be further formed with a protruding part <NUM>, the protruding part <NUM> may increase the tightness of the fixing tenons <NUM> into the tenon fixing groove <NUM>. This provides a more stable fixation of the laminate <NUM> on the frame <NUM>.

Referring to <FIG> are the schematic diagrams illustrating a folding storage cabinet according to an example implementation of the present disclosure. Please refer to <FIG>, <FIG>, and <FIG>. The first side plate <NUM> and the second side plate <NUM> shown in <FIG>. are formed with the third side plate pivot part <NUM> and the fourth side plate pivot part <NUM>. One side of the first side plate <NUM> formed with the third side plate pivot part <NUM> is formed with at least one anti-bending component <NUM>, and the second side plate <NUM> formed with the fourth side plate pivot part <NUM> is formed at least one more top pillar <NUM>. The anti-bending component <NUM> is formed with a curved slotted hole <NUM>, which may be used for the top pillar <NUM> to press against. When the first side plate <NUM> and the second side plate <NUM> are connected together, the top pillar <NUM> will be snap into the slotted hole <NUM> of the anti-bending component <NUM>. Thus, when the top plate <NUM>, the bottom plate <NUM>, and the laminate <NUM> of the folding storage cabinet <NUM> have completed the storage process, the storage space <NUM> of the folding storage cabinet <NUM> will be in a state without any object providing support. After the top pillar <NUM> is inserted into the slotted hole <NUM> of the anti-bending component <NUM>, it may provide improved resistance to bending for the connected first side plate <NUM> and second side plate <NUM>, as shown in <FIG>. It prevents the first side plate <NUM> and the second side plate <NUM> from experiencing bending deformation when subjected to minor external forces in a state where the storage space <NUM> is without any object providing support.
