[0036] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0037] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0038] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” etc. are used only as markers and are not a limitation on the number of objects or their order.

[0039] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a detachable connection, a detachable connection, or an integral part; it may be a direct connection or an indirect connection through an intermediate medium.

[0040] In order to increase the interactivity and fun of the audience during the imperial concubine parade performance, interactive elements will be added to the performance. The current interactive elements involve placing interactive products inside the performance box.

[0041] The performance box in related technologies includes a storage box and a shelf layer placed inside the storage box. With the rapid development of the tourism industry, the number of visitors increases exponentially during peak tourist seasons. When there are many audience members, the limited number of interactive products placed on the shelf layer makes it impossible to achieve sufficient interaction with the audience. To solve this problem, related technologies have taken several approaches: First, prepare multiple performance boxes to carry more interactive products during the parade, but this increases manpower and material resources, raising costs. Second, directly stack multiple shelf layers inside a single box, but this can damage some interactive products. Third, during the parade, carry only a large number of interactive products, and after distributing the interactive products in the performance box, place the carried interactive products back on the shelf layer before continuing the interaction. This method results in discontinuous interaction and adds extra work.

[0042] To solve the above problems, this invention discloses a performance device, see [link to details]. Figure 1 and Figure 2 The performance equipment includes a performance box and multiple partition placement layers 7, having a box lid 2 and a box body; the box body has a placement cavity; the inner wall of the placement cavity has multiple stepped surfaces 9 arranged sequentially along the side away from the box lid 2; along the direction away from the box lid 2, the edge size of each stepped surface 9 gradually decreases (in other words, the stepped surfaces are arranged sequentially from the center of the box body to both sides, and each stepped surface gradually approaches the center of the box body from top to bottom); a partition placement layer 7 is placed at the bottom of the placement cavity and at least part of each stepped surface 9 (for example, the partition placement layer 7 can be placed only on the stepped surfaces; or, for example, the partition placement layer 7 is placed at the bottom of the placement cavity and on each stepped surface 9), and the size of the partition placement layer 7 gradually increases along the direction closer to the box lid 2 (the size of the partition placement layer 7 is adapted to the size of each stepped surface 9). See also Figure 2 The partition layer 7 has multiple placement slots 8 for placing interactive products. In this disclosure, the internal placement cavity of the box has a stepped surface 9, allowing for more partition layers 7 to accommodate more interactive products. Furthermore, the stepped surface 9 design allows for the placement of partition layers 7 of different sizes for various interactive products, making it highly versatile. Additionally, the stepped surface 9 design allows for the quick removal of partition layers 7 without interactive products during interaction with the audience, ensuring continuity of interaction and improving audience satisfaction.

[0043] In one embodiment of this disclosure, see [link to relevant documentation]. Figures 2-5The enclosure comprises a storage box 1 and multiple stepped structures 3. The stepped structures 3 are evenly arranged within the placement cavity, with a first gap between any two adjacent stepped structures 3. In this disclosure, the stepped structures 3 and the storage box 1 are set independently, allowing the same function to be achieved simply by adding the stepped structures 3 to the existing storage box, eliminating the need to reorder related performance equipment and reducing costs. Furthermore, in this disclosure, the combination of multiple stepped structures 3 forms multiple stepped surfaces 9 within the placement cavity, and the first gap between each stepped structure 3 facilitates the removal or placement of the partition placement layer 7. When there are many interactive participants, this first gap greatly accelerates the removal efficiency of the partition placement layer 7 (after the upper interactive products are distributed, the upper partition placement layer 7 needs to be removed to distribute the interactive products on the lower partition placement layer 7), improving the continuity of interaction.

[0044] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 4 and Figure 5 The step structure 3 has multiple sub-step plates 31. Along the direction away from the lid 2, in any two adjacent sub-step plates 31, the orthographic projection of the lower sub-step plate 31 on the storage box 1 is greater than the orthographic projection of the upper sub-step plate 31 on the storage box 1, and the orthographic projection of the upper sub-step plate 31 on the storage box 1 is within the orthographic projection of the lower sub-step plate 31 on the storage box 1. In other words, along the direction away from the lid 2, the size of the sub-step plate 31 gradually increases. In this disclosure, the size of the sub-step plate 31 increases along the direction close to the center of the box body so as to form a step surface 9.

[0045] Each sub-step plate 31 is detachably connected to the storage box 1 via a fixing structure 4. In this disclosure, the step structure 3 is divided into multiple sub-step plates 31, which are detachably connected to the storage box 1, facilitating disassembly. When a sub-step plate 31 is damaged and needs to be replaced, only the damaged sub-step plate 31 needs to be replaced, without replacing the entire step structure 3, thus reducing costs. Furthermore, the corresponding sub-step plates 31 can be selectively set according to the size of the interactive product and the partition layer 7, making it more adaptable (for example, when the height of the interactive product is large, the sub-step plates 31 can be set at intervals, and the gap between two adjacent sub-step plates 31 can be larger to prevent the interactive product from being squeezed by the upper partition layer 7).

[0046] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 4The fixing structure 4 consists of fixing bolts; the sub-step plate 31 has a snap-fit ​​groove, and the fixing bolts pass through the storage box 1 and snap into the snap-fit ​​groove. In this disclosure, a step structure 3 (sub-step plate 31) can be added to the existing storage box 1. This eliminates the need to redesign the performance equipment, avoids excessive cost increases, and the use of fixing bolts for snap-fit ​​fixation facilitates installation and replacement, offering high versatility and low cost. In this disclosure, the fixing bolt portions exposed on the outside of the storage box 1 can be painted with a color layer, making the entire performance equipment more aesthetically pleasing. When it is not necessary to install too many sub-step plates 31, shorter fixing bolts can be used to seal the bolt holes on the storage box 1. This ensures the integrity of the storage box 1 and provides dustproof effects without interfering with the installation of other internal sub-step plates 31.

[0047] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 3 and Figure 5 Each sub-step plate 31 has a first surface facing the center of the central storage box 1; the first surface has an inclined surface 5 and a snap-fit ​​surface 6 connected to each other, the inclined surface 5 is set near the box cover 2 (in other words, the distance between the edge of the inclined surface 5 near the box cover 2 and the corresponding side of the box body is less than the distance between the edge of the inclined surface 5 away from the box cover 2 and the corresponding side of the box body, it can be understood that the inclined surface 5 is set towards the box cover 2), the snap-fit ​​surface 6 is attached to the outer edge of the partition placement layer 7 (it can be understood that the partition placement layer 7 is snapped into the area enclosed by the snap-fit ​​surface 6 in the same layer); the edge of the inclined surface 5 near the box cover 2 is located between the storage box 1 and the snap-fit ​​surface 6; the horizontal distance between any two adjacent inclined surfaces 5 is not less than 3cm (for example, the horizontal distance between any two adjacent inclined surfaces 5 is equal to 3cm, 4cm, 5cm, 8cm, etc.). In this disclosure, an inclined surface 5 is provided to guide the placement of the partition layer 7. This eliminates the need for high-precision alignment of the partition layer 7 with the area enclosed by the snap-fit ​​surfaces 6 on the same layer. The inclined surface 5 allows it to automatically slide into the area enclosed by the snap-fit ​​surfaces 6 under gravity, or with the aid of external force. This improves the flexibility and efficiency of partition layer 7 placement. Furthermore, this disclosure specifies that the horizontal distance between any two adjacent inclined surfaces 5 is no less than 3 cm, ensuring sufficient contact area between the partition layer 7 and the step surface 9, thus guaranteeing stable support of the partition layer 7 by the step structure 3.

[0048] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 2 The stepped structure 3 has a first end face 12 near the box cover 2, and the distance between the first end face 12 and the end face of the storage box 1 is not less than the thickness of the partition layer 7. Thus, in this disclosure, a partition layer 7 can be added to the end face of the stepped structure 3, thereby further increasing the number of interactive products.

[0049] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 2 and Figure 6 The partition layer 7 has a first structural layer 11 and a first reinforcing layer 10 covering the first structural layer 11; the material of the first structural layer 11 is foam board.

[0050] In other words, the partition layer 7 in this disclosure is formed in the following way:

[0051] First, the foam board is made to form a corresponding structure to obtain the first structural layer 11. Then, a foam curing agent is applied to the entire foam board. After the foam curing agent is cured, the first reinforcing layer 10 is formed, which is the corresponding partition placement layer 7.

[0052] In one embodiment of this disclosure, the partition layer 7 may be coated with other color layers so that the color of the partition layer 7 matches the color of the entire performance equipment, thereby improving aesthetics. For example, the partition layer 7 may be sprayed with gold paint.

[0053] In this disclosure, the partition layer 7 uses foam board as the base material, resulting in a lighter weight compared to wood, thus reducing the overall weight of the performance equipment. After being coated with a foam curing agent, it achieves high hardness, providing stable support for the interactive products, and also at a lower cost. If any partition layer 7 is damaged, it can be replaced at a low cost. Furthermore, since most foam boards are considered waste, this disclosure utilizes the foam boards for reuse, further reducing costs.

[0054] In one embodiment of this disclosure, the sub-step plate 31 has a second structural layer and a second reinforcing layer covering the second structural layer; the second structural layer is made of foam board, and the second reinforcing layer is formed by coating the foam board with a foam curing agent. In other words, the sub-step plate 31 in this disclosure is formed in the following manner:

[0055] First, the foam board is made to form a corresponding structure to obtain the second structural layer. Then, a foam curing agent is applied to the entire foam board. After the foam curing agent is cured, a second reinforcing layer is formed, which is the corresponding sub-step plate 31.

[0056] In one embodiment of this disclosure, the sub-step plate 31 can be coated with other color layers to match the color of the entire performance equipment, improving aesthetics. For example, the sub-step plate 31 can be sprayed with gold paint. In this disclosure, the sub-step plate 31 uses foam board as the base material, resulting in a relatively low weight that does not increase the overall weight of the performance equipment. After applying a foam curing agent, it achieves high hardness, providing stable support for the partition placement layer 7, and has a low cost. If any sub-step plate 31 is damaged, it can be replaced at a low cost. Furthermore, since most foam boards are considered waste, this disclosure reuses the foam boards, further reducing costs.

[0057] In one embodiment of this disclosure, the ratio of the height of the inclined surface 5 along the first direction to the height of the latching surface 6 along the first direction is no greater than 2 / 3 (for example, the ratio of the height of the inclined surface 5 along the first direction to the height of the latching surface 6 along the first direction is equal to 2 / 3, 1 / 2, 1 / 3, etc.). In this disclosure, limiting the height of the inclined surface 5 and the latching surface 6 in the first direction serves two purposes: firstly, it controls the height of the sub-step plate 31 along the first direction; secondly, it allows the latching surface 6 to be as large as possible, thus making the latching surface 6 more securely engaged with the partition layer 7. This reduces the likelihood of the interactive product shifting due to excessive shaking of the partition layer 7 caused by the movement of the performance equipment (where staff use connecting rods to move the performance equipment). Here, the first direction refers to the arrangement direction of the lid 2 and the body of the box; when the performance equipment is placed upright on the ground, the first direction is vertical.

[0058] In one embodiment of this disclosure, a lifting column (not shown in the figure) is provided between any two adjacent sub-step plates 31 along the first direction, so that a second gap exists between any two adjacent sub-step plates 31. When the second gap exists, the size of the fixing structure should be as large as possible to ensure the stability of the installation and support of the sub-step plates 31. The lifting column in this disclosure is detachably connected to the sub-step plate 31. The membrane structure of the lifting column can be the same as the membrane structure of the sub-step plate 31, including a third structural layer and a third reinforcing layer. When fixing the lifting column to the sub-step plate 31, a fixing rod insertion method can be used (one end of the fixing rod is inserted into the corresponding sub-step plate 31, and the other end is inserted into the lifting column). This facilitates replacement and is easy to operate without additional procedures.

[0059] This disclosure provides a second gap between any two sub-step plates 31, which allows for the placement of partition layers 7 of different thicknesses based on different interactive products within the performance equipment; secondly, it can prevent the upper partition layer 7 from squeezing the interactive products on the lower partition layer 7, thus avoiding damage to the interactive products.

[0060] In one embodiment of this disclosure, the box cover 2 has a telescopic hook (not shown in the figure). When the box cover 2 is opened, the telescopic hook can be manually extended out of the box cover 2. In this way, the partition layer 7 for which interactive products have been distributed and which do not have interactive products can be hung on the telescopic hook, avoiding the situation of being trampled on the ground, needing to be placed in a far place, or needing to be manually stored.

[0061] In one embodiment of this disclosure, a snap-fit ​​structure (not shown in the figure) may be provided between the box body and the box lid 2. This snap-fit ​​structure is used to fix the position between the box lid 2 and the box body when the box lid 2 is opened. In one example, the snap-fit ​​structure includes a snap-fit ​​rod. The end face of the box body has a sliding groove, and a slider is disposed within the sliding groove. One end of the snap-fit ​​rod is connected to the slider, and the other end is connected to a corresponding position on the box lid 2. The slider is completely positioned within the sliding groove, which has a snap-fit ​​groove away from the box lid 2. The size of the snap-fit ​​groove is adapted to the size of the slider (the size of the snap-fit ​​groove can be slightly larger than the size of the slider). Thus, when the box lid 2 is opened, the snap-fit ​​rod and sliding motion are activated. During the sliding process, the slider can be positioned within the snap-fit ​​groove, and the position between the box body and the box lid 2 is fixed by the limiting effect of the snap-fit ​​groove. To prevent the slider from moving out of the sliding groove, the opening size of the sliding groove is smaller than the size of the slider.

[0062] In one embodiment of this disclosure, the opening size of the sliding groove is larger than the width of the snap-fit ​​rod, and the length of the sliding groove must be sufficient to fully accommodate the snap-fit ​​rod. In this way, when the cover 2 is fastened to the box body, the snap-fit ​​rod can be completely placed inside the sliding groove and will not interfere with the fastening of the cover 2.

[0063] In another example of this disclosure, a strap (not shown in the figure) connects the lid 2 to the box body. This allows the lid 2 to be held in place at a certain point after it is opened, preventing it from falling completely and colliding with the box body, which could cause the paint on the exterior of the box body to peel off. In this example, the inner wall of the lid 2 may have an elastic element. One end of the elastic element is fixed to the lid, and the other end is connected to the strap. This allows the strap to be retracted into the performance equipment through the elastic element when the lid 2 is closed, ensuring the aesthetics of the parade.

[0064] In one embodiment of this disclosure, the storage box 1 includes a box frame and a panel surrounding the box frame. The storage box 1 is manufactured in this manner, which can reduce the weight of the entire performance equipment.

[0065] In one embodiment of this disclosure, the structure of the lid 2 is the same as that of the storage box 1.

[0066] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
