DETAILED DESCRIPTION

[0037] Exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure can be embodied in various forms without being limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0038] It should be noted that unless otherwise specified, technical terms or scientific terms used in the present application should be understood as their common meanings to those skilled in the art to which the present application pertains.

[0039] As shown in FIGS. 1 and 2, the present application provides a holding device, comprising: Figure 1 and Figure 2 As shown in FIGS. 1 and 2, the present application provides a holding device, comprising:

[0040] A housing 1 forms at least one accommodating space 11, at least two opposite inner side walls of the accommodating space 11 are first inclined surfaces 12 for bearing target objects 3, the sizes of the target objects 3 correspond to the bearing positions of the first inclined surfaces 12, and different bearing positions correspond to different sizes of the target objects 3.

[0041] A stop structure 2 is used to fix the target objects 3 to the corresponding bearing positions.

[0042] The target objects 3 of the present application can be computers and accessories (such as notebook computers, displays, etc.), or ceramic and glass products (such as vases, tableware, etc.), and the like.

[0043] The housing 1 is used to provide a safe accommodating space 11 for the target objects 3. The housing 1 with at least one accommodating space 11 can be formed by injection molding, modular splicing, or 3D printing, etc. The accommodating space 11 can have an opening for taking and placing the target objects 3 and a bottom surface. The bottom surface of the accommodating space 11 can be opposite to the opening along a first direction to ensure the stability of the structure and enhance the protection effect of the electronic device away from the opening side. The bottom surface can be provided with patterns or trademarks and other marks as needed.

[0044] The first inclined surface 12 and the bottom surface have an obtuse angle included angle, so that the target objects 3 of different sizes entering from the opening can be stably placed on the at least two opposite first inclined surfaces 12, that is, the at least two first inclined surfaces 12 have a plurality of bearing positions along the first direction, and different bearing positions correspond to different sizes of the target objects 3. The specific angle degree of the first inclined surface 12 and the bottom surface can be designed according to the size and shape of the target objects 3 to support target objects 3 of different sizes.

[0045] The accommodating space 11 can have two, three, four or even more inner side walls as the first inclined surfaces 12, of which at least two first inclined surfaces 12 are opposite to each other to ensure the stability of the first inclined surfaces 12 when bearing the target objects 3. The at least two first inclined surfaces 12 can be distributed at intervals; or the at least two first inclined surfaces 12 can be in a continuous ring shape, for example, the at least two first inclined surfaces 12 can be in a circular ring shape, at which time the accommodating space 11 is a circular truncated cone type to provide more stable support.

[0046] There may be one accommodating space 11, in which case the accommodating space 11 is used to accommodate the target object 3; or there may be two accommodating spaces 11, in which case the two accommodating spaces 11 can be connected to each other, wherein the first accommodating space 111 is used to accommodate the target object 3, at least two opposing inner sidewalls of the first accommodating space 111 are first inclined surfaces 12, and part of the inner sidewalls of the first accommodating space 111 can be recessed inward to form the second accommodating space 112. When picking up or putting down the target object 3, the operator can put his hand into the second accommodating space 112, which makes the operation easier and improves convenience and safety.

[0047] The shape of the cross-section of the receiving space 11 can be the same as the shape of the cross-section of the target object 3. For example, when the cross-section of the target object 3 is rectangular, the cross-section of the receiving space 11 can be rectangular; when the cross-section of the target object 3 is circular, the cross-section of the receiving space 11 can be circular, and so on. Alternatively, the shape of the cross-section of the receiving space 11 can be different from the shape of the cross-section of the target object 3. For example, when the cross-section of the target object 3 is irregular, the cross-section of the receiving space 11 can be rectangular or circular, etc., to simplify the processing flow of the shell 1. When the cross-section of the target object 3 is rectangular, the cross-section of the receiving space 11 can be circular. In this case, the target object 3 does not completely fit against the side wall of the receiving space 11, which is more conducive to the operator picking up and placing the target object 3.

[0048] The shell 1 can be made of materials such as polypropylene and polyethylene.

[0049] The stop structure 2 is used to enhance the stability of the target object 3. The stop structure 2 may include at least two oppositely arranged straps. The first ends of the at least two straps may be connected to the bottom surface by means of adhesive or buckles. The inner sidewall of the receiving space 11 may form at least two receiving grooves, and each strap may be completely received in one receiving groove to avoid the straps affecting the load-bearing effect on the target object 3. At the same time, this concealed design also extends the service life of the straps. After the target object 3 is placed in the load-bearing position, the at least two straps may cross each other to bind the target object 3, providing restraint to the target object 3, thereby reducing the movement of the target object 3 and enhancing the reliability of the fixation. The length of the straps should ensure that the target object 3 can be tightened, while leaving a certain adjustment margin to achieve binding of target objects 3 of all sizes. The specific length can be designed according to the size of the target object 3.

[0050] The containing device of the present application contains target objects 3 of different sizes through the containing space 11 of the shell 1. The containing space 11 has at least two opposite inner side walls that are first inclined surfaces 12. The first inclined surfaces 12 have multiple bearing positions due to their inclined characteristics, thereby achieving the bearing of target objects 3 of different sizes and improving the versatility and flexibility of the containing device, which is suitable for containing target objects 3 of various sizes. The stop structure 2 is used to firmly fix the target objects 3 in their corresponding bearing positions, preventing displacement or tilting of the target objects 3 during transportation or storage. This fixing mechanism enhances the safety of the target objects 3 and ensures the integrity of the target objects 3.

[0051] As shown in Figures 1 to 4 some embodiments, the stop structure 2 includes:

[0052] The cover 21 is movably connected to the shell 1, and the cover 21 can move to place the containing space 11 in an open state or a closed state.

[0053] When the containing space 11 is in the closed state, the cover 21 can fix the target objects 3 to the corresponding bearing positions.

[0054] The shape and size of the cover 21 match those of the shell 1 to ensure that the cover 21 can achieve the functions of closing and protection. The cover 21 can be connected to the shell 1 in a folding manner, for example, the cover 21 can be connected to the shell 1 through a hinge. Alternatively, when both the cover 21 and the shell 1 are made of paper materials, the cover 21 and the shell 1 can be folded by the paper materials, and a preset fold line can be provided at the connection between the cover 21 and the shell 1 to achieve smooth flipping of the cover 21.

[0055] The cover 21 ensures that the containing space 11 can be completely closed in the closed state, preventing external environments (such as dust and moisture) from damaging the target objects 3. In addition, the cover 21 also has a restraining function. In the closed state, the cover 21 can firmly fix the target objects 3 in their corresponding bearing positions, reducing the possibility of movement of the target objects 3 and enhancing the stability of the target objects 3.

[0056] As shown in Figure 1 and Figure 2 some embodiments, the stop structure 2 further includes:

[0057] The buffer assembly 22 has a first end connected to the cover 21. The end face of the first end of the buffer assembly 22 is completely or partially coincident with the lower surface of the cover 21.

[0058] When the containing space 11 is in the closed state, the second end of the buffer assembly 22 can abut against the target objects 3.

[0059] The buffer component 22's buffering characteristics not only secure target objects 3 of different sizes, but also effectively absorb and disperse external impact forces, reducing direct impact on the target objects 3 and achieving buffer protection. The first end of the buffer component 22 can be bonded to the cover 21; or, the first end of the buffer component 22 can be embedded in the cover 21.

[0060] The cushioning component 22 can be made of silicone, sponge, or other materials. The first end face of the cushioning component 22 can completely overlap with the lower surface of the cover 21 to increase the contact area between the cushioning component 22 and the cover 21, provide a uniform pressure distribution, and enhance the overall stability; or, the first end face of the cushioning component 22 can partially overlap with the lower surface of the cover 21 to reduce production costs and achieve a lightweight design.

[0061] like Figure 1 and Figure 2 As shown, in some embodiments, the buffer component 22 includes:

[0062] An elastic element (not shown in the figure) has its first end connected to the cover 21;

[0063] The expansion plate 221 is connected to the second end of the elastic member. The expansion plate 221 can abut against the target object 3. The elastic deformation of the elastic member is different for different bearing positions.

[0064] The elastic element can constrain target objects 3 of different sizes by utilizing its elasticity, while absorbing and dispersing external impact forces to achieve buffer protection for the target objects 3. The first end of the elastic element can be connected to the cover 21 by snap-fit ​​or adhesive, and the end face of the first end of the elastic element can completely or partially overlap with the lower surface of the cover 21. When the accommodating space 11 is closed, the direction of expansion and contraction of the elastic element can be consistent with the first direction. For target objects 3 of the same size along the first direction, the closer the bearing position is to the elastic element, the greater the elastic deformation of the elastic element; the farther the bearing position is from the elastic element, the smaller the elastic deformation of the elastic element. The elastic element can be a metal spring or a rubber spring, or a paper spring, to meet environmental protection requirements and achieve lightweight design. The number of elastic elements can be one or more, and when there are multiple elastic elements, they can be arranged at intervals.

[0065] The expansion plate 221 has a large contact area with the target object 3, uniformly transmits the force applied by the elastic member to the surface of the target object 3, enhances the fixing effect, and ensures the integrity of the target object 3. The expansion plate 221 can be connected with the second end of the elastic member by adhesion or clamping. The expansion plate 221 can be a circular plate or a rectangular plate, and the specific shape can be designed according to the shape of the target object 3 to better adapt to the shape of the target object 3. The expansion plate 221 can be made of metal or plastic to improve the fixing effect; or the expansion plate 221 can be made of materials such as silica gel, rubber, or foam to provide buffering and damping functions and ensure the integrity of the target object 3.

[0066] As shown in Figure 1 and Figure 2 , the buffer assembly 22 further comprises:

[0067] The flexible member 222 is connected with the cover 21 and the expansion plate 221 respectively, and the flexible member 222 can form a surrounding space with the cover 21 and the expansion plate 221, and the elastic member is located in the surrounding space.

[0068] The surrounding space can protect the elastic member from being exposed to the outside and reduce the influence of the external environment on it. In addition, this hidden design makes the overall structure more simple and meets the aesthetic design. The flexible member 222 can be connected with the cover 21 by adhesion or clamping, and the flexible member 222 can be connected with the peripheral edge of the expansion plate 221 by adhesion or embedding. The flexible member 222 can form a completely enclosed surrounding space with the expansion plate 221 and the cover 21 to completely wrap the elastic member inside to maximize the protection of the elastic member while maintaining the beauty and cleanliness of the overall structure; or the flexible member 222 can form a partially enclosed surrounding space with the expansion plate 221 and the cover 21 to provide some shielding and protection for the elastic member and achieve lightweight design.

[0069] The flexible member 222 does not affect the elastic deformation of the elastic member while forming the surrounding space. The flexible member 222 can be made of fabric or cloth; or the flexible member 222 can be made of paper material and folded into a flexible structure, such as Z-shaped folding, honeycomb folding, etc., to meet the environmental protection requirements. The number of flexible members 222 can be one; or the number of flexible members 222 can be multiple, for example, when the expansion plate 221 is rectangular, the number of flexible members 222 can be four, and each flexible member 222 is located on one side of the expansion plate 221 to achieve enclosure.

[0070] As shown in Figure 1 and Figure 2 , the cross-sectional area of the buffer assembly 22 gradually decreases from the first end to the second end.

[0071] The buffer assembly 22 can be frustum-shaped or wedge-shaped, with its cross-sectional area gradually decreasing from the first end (near the cover 21) to the second end (near the expansion plate 221). This gradual decrease in cross-sectional area allows stress to be gradually dispersed along the length, preventing stress concentration in a specific area and thus improving the overall durability and reliability of the buffer assembly 22. Upon impact, the larger cross-sectional area (first end) provides greater initial support, while the gradually decreasing cross-sectional area gradually absorbs energy in subsequent processes, providing a more uniform buffering effect and reducing the instantaneous impact on the target object 3. Furthermore, the smaller cross-sectional area at the second end allows for avoidance of specific locations on the target object 3, ensuring its integrity.

[0072] like Figure 3 and Figure 4 As shown, the cover 21 forms at least one accommodating space 211 communicating with the accommodating space 11, and at least two opposing inner sidewalls of the accommodating space 211 are second inclined surfaces 212.

[0073] When the accommodating space 11 is closed, the second inclined surface 212 can abut against the target object 3. The size of the target object 3 corresponds to the abutment position of the second inclined surface 212, and different bearing positions correspond to different abutment positions.

[0074] When the accommodating space 11 is closed, part of the target object 3 can be accommodated in the accommodating space 11, and another part of the target object 3 can be accommodated in the accommodating space 211. The formation method and specific structure of the accommodating space 211 can be referred to the accommodating space 11; the specific design method of the second inclined surface 212 can be referred to the first inclined surface 12, and will not be described again here.

[0075] The second inclined plane 212 and the first inclined plane 12 can have the same inclination angle to ensure symmetry and consistency, in which case the accommodating space 211 and the receiving space 11 can be mirror images of each other; the second inclined plane 212 and the first inclined plane 12 can have different inclination angles to accommodate target objects 3 of different shapes or sizes, providing a more personalized protection solution. The shape of the cross-section of the accommodating space 211 can be the same as the shape of the cross-section of the receiving space 11, for example, both of them have a circular or rectangular cross-section; or, the shape of the cross-section of the accommodating space 211 can be different from the shape of the cross-section of the receiving space 11, for example, one of them has a circular cross-section and the other has a rectangular cross-section; or, one is irregular and the other is elliptical, etc.

[0076] The combined design of the accommodation space 211 and the containing space 11 can make full use of the limited space, so that the entire containing device is more compact, saves storage space, does not need to introduce additional components, simplifies the overall structural design, reduces the assembly steps and complexity, and reduces the production cost.

[0077] As shown in Figure 3 and Figure 4 , the stop structure 2 comprises:

[0078] A plurality of clamping portions (not shown in the figure) are arranged along the inclined direction of the first inclined surface 12, and the clamping portions can clamp the target object 3.

[0079] The shape of the clamping portion is matched with the shape of the target object 3 to achieve clamping with the target object 3 and prevent displacement of the target object 3 during transportation or storage. The first inclined surface 12 can be provided with a plurality of stepped surfaces along the inclined direction thereof, and two adjacent stepped surfaces are connected by a limiting surface. The plurality of stepped surfaces of at least two opposite first inclined surfaces 12 can be one-to-one opposite, and the stepped surfaces of at least two first inclined surfaces 12 opposite to each other form a bearing position together, and the stepped surfaces of at least two first inclined surfaces 12 opposite to each other and the limiting surface adjacent to the stepped surface and close to the opening form a clamping portion. In the case that the at least two first inclined surfaces 12 are in a continuous ring shape, each clamping portion can be in a ring shape.

[0080] In the case that the cover 21 has the accommodation space 211, the cover 21 can also be provided with a plurality of clamping portions, and the cover 21 can refer to the way in which the shell 1 is provided with the clamping portions to enhance the fixing effect of the target object 3.

[0081] As shown in Figure 1 and Figure 2 , the shell 1 comprises:

[0082] The first sub-shell 131 has a first sub-containing space 131;

[0083] The second sub-shell 141 has a second sub-containing space 141; the second sub-shell 141 is located in the first sub-containing space 131, and the outer side wall of the second sub-shell 141 is attached to the inner side wall of the first sub-shell 131.

[0084] Among them, the second sub-containing space 141 can contain target objects 3 of different sizes, and at least two opposite inner side walls of the second sub-containing space 141 are the first inclined surfaces 12.

[0085] The inner side walls of the first sub-shell 131 can all extend in the first direction, facilitating production and processing; or, at least part of the inner side walls of the first sub-shell 131 can be inclined to form a third inclined surface, to provide better stress dispersion effect. The outer side walls of the second sub-shell 141 match the shape and size of the inner side walls of the first sub-shell 131, so that the outer side walls of the second sub-shell 141 fit the inner side walls of the first sub-shell 131, ensuring the stability of the whole. The outer side walls of the second sub-shell 141 can be bonded with the inner side walls of the first sub-shell 131; or, the second sub-shell 141 can be placed in the first sub-shell 131, and so on. The second sub-shell 141 can be placed in the entire first sub- containing space 131 to achieve complete placement and provide the best protection effect; or, the second sub-shell 141 can be placed in part of the first sub-containing space 131, leaving a margin in the first sub-containing space 131. During the bearing process of the first inclined surface 12, part of the target object 3 can be contained in the second sub-containing space 141, and the other part of the target object 3 can be contained in the first sub-containing space 131, achieving the containment and bearing of target objects 3 of more sizes and improving the versatility.

[0086] The first sub-shell 131 and the second sub-shell 141 are nested to form a compact whole, significantly improving the stability and protection performance of the whole, maintaining the safety of the target object 3, and optimizing the space utilization and user experience.

[0087] As shown in Figures 1 to 4 The inclination angles of the at least two first inclined surfaces 12 are the same or different;

[0088] The same inclination angles of the at least two first inclined surfaces 12 can ensure that the stress is uniformly distributed in all directions, reduce local stress concentration, improve the stability and durability of the whole structure, and more facilitate standardized production and improve production efficiency. The different inclination angles of the at least two first inclined surfaces 12 can better adapt to the complex shape of the target object 3 and provide more personalized adaptation scheme. In the case that the cover body 21 has a containing space 211, the inclination angles of the at least two second inclined surfaces 212 are the same or different. And / or,

[0089] The material of the shell 1 is a degradable material; and / or,

[0090] The material of the stop structure 2 is a degradable material.

[0091] The degradable material can be quickly decomposed into harmless substances in the natural environment, reducing long-term waste and reducing the negative impact on the environment. The degradable material can be selected from paper materials (such as corrugated paper, cardboard, etc.) made of wood fibers or other plant fibers, or paper pulp molded by paper pulp, or wood-plastic composites mixed from wood fibers and degradable plastics. The shell 1 and the stop structure 2 can be made of degradable materials, or the shell 1 and the stop structure 2 can be made of degradable materials.

[0092] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
