[0021] As most electronic products become smaller, products requiring EMI (Electromagnetic Interference) protection need additional metal shielding. Traditionally, this involves combining relatively independent upper and lower metal shells to form the shield. Assembling these shells typically involves snap-fitting or welding to create a single structure that encloses the PCB (Printed Circuit Board). This process is space-consuming in terms of structural design, cumbersome to assemble, and detrimental to ease of operation.

[0022] This utility model proposes a shell structure 100 and an electronic product to solve the above problems.

[0023] Please see Figures 1 to 2In one embodiment of the present invention, the shell structure 100 includes a plate 1 extending along a first direction and a second direction. A plurality of hollow holes 2 spaced apart along the first direction are provided on the plate 1. A spacer 3 is formed between two adjacent hollow holes 2. The spacer 3 has a spacing width in the first direction. The two inner wall surfaces of two adjacent hollow holes 2 that are close to each other in the first direction are at least partially arranged to extend back to back, so that in the second direction, the spacer 3 has a foldable area with the smallest spacing width. The foldable areas of the plurality of spacers 3 are located on the axis extending along the first direction.

[0024] The first direction and the second direction are two mutually perpendicular directions within the same plane. Furthermore, the aforementioned plate 1 is a metal structural component. In actual use, the entire plate 1 can be bent to form a complete shell structure 100, thereby encapsulating and fixing electrical components and forming a shielding structure. During the bending operation, to ensure that the plate 1 undergoes bending deformation at a preset position, such as... Figure 1 As shown, the plate 1 has a plurality of perforated holes 2 spaced apart along a first direction. A spacer 3 is formed between one end of two adjacent perforated holes 2. Specifically, the spacer 3 is formed between two inner wall structures of two adjacent perforated holes 2 that are close to each other. Furthermore, the two inner wall surfaces of two adjacent perforated holes 2 that are close to each other in the first direction extend at least partially away from each other, so the width of the spacer 3 gradually increases along the opposite extension direction of the two inner wall surfaces. At this time, a foldable area with the smallest spacing width is formed on the spacer 3. Since the plurality of perforated holes 2 are evenly distributed at intervals in the first direction, a plurality of foldable areas are formed in the first direction, and the plurality of foldable areas are located on the same axis. Therefore, during the actual bending process, the entire plate 1 can simultaneously undergo bending deformation at multiple foldable areas, ensuring the consistency of the bending position as much as possible.

[0025] Meanwhile, since the main body is a metal structural component, it has good ductility and plasticity. After bending to form the outer shell structure, the entire shell structure 100 can have a relatively stable shape. Furthermore, the shell structure 100 formed by bending the plate 1 is an integral shell. Traditional shell structures 100 are assembled structures, with the upper and lower iron shells being relatively separate. In actual installation, the upper and lower iron shells need to be pre-positioned and then fastened or welded to cover the corresponding electrical components. This process is more space-consuming in terms of structural design and is more troublesome to assemble. Compared with a split structure, the integral structure has better overall structural strength.

[0026] Furthermore, in some smaller precision instruments, the overall dimensions of the shielding housing structure 100 for certain components also need to be as small as possible. The aforementioned integrated bent housing structure 100 occupies less vertical space, thus allowing for better feasibility in structural design for more products, and also enabling greater possibilities for product innovation.

[0027] The inner wall surface of the hollow hole 2 in the first direction includes a curved section 211 and a straight section 212 connecting the curved section 211. The straight sections 212 of two adjacent hollow holes 2 are arranged in parallel, and the two curved sections 211 of two adjacent hollow holes 2 that are close to each other in the first direction extend in opposite directions. The foldable area is set corresponding to the straight section 212 of the hollow hole 2.

[0028] The perforated hole 2 corresponds to a wall shape in the easily foldable area that is mainly composed of a straight section 212 and a curved section 211. Two curved sections 211 that are close to each other in the first direction extend back to forth. For example... Figure 1 , Figure 2 and Figure 3 As shown, the curved surface segment 211 is set in the form of an arc surface. As the curved surface segment 211 extends towards the end of the plate 1 in the second direction, the gap width formed between two adjacent hollow holes 2 gradually increases. At this time, the gap distance between the two straight surface segments 212 forms the minimum gap width, and the easily foldable area is also formed between the two straight surface segments 212.

[0029] As can be seen from the above, by setting the curved surface segment 211, a foldable region with the smallest gap can be formed between the two hollow holes 2. In another embodiment of this utility model, the above-mentioned foldable region can also be formed by setting a planar angle structure. Specifically, multiple hollow holes 2 can be set in the first direction, and two planar angles can be set at both ends of the hollow holes 2 in the first direction, so that the vertices of the two planar angles in the multiple hollow holes 2 are located on the same axis in the first direction. At this time, the vertices of the angles between the two adjacent ends of two adjacent hollow holes 2 form a foldable region with the smallest gap width. When performing a specific bending operation, the plate 1 can be bent on the bending axis formed by the vertices of the multiple planar angles.

[0030] In one embodiment of this utility model, the plurality of hollow holes 2 are not arranged on the same straight line in the first direction. Specifically, the plurality of hollow holes 2 are evenly spaced in the first direction, and two adjacent hollow holes 2 are partially staggered in the second direction, so that the curved sections 211 of two adjacent hollow holes 2 are staggered in the second direction and the bending directions are opposite, and the extension direction of the straight section 212 is set at an angle to the first direction.

[0031] With the above structural design, multiple foldable regions can be formed on the same axis in the first direction, and the force on both sides of the foldable regions in the second direction is relatively uniform, ensuring that bending deformation can be formed at multiple foldable regions during the bending process.

[0032] In one embodiment of the present invention, the hollow hole 2 includes a square hole segment 22 and a triangular hole segment 21, and the triangular hole segments 21 in two adjacent hollow holes 2 are arranged close to each other; the spacer 3 is formed between two adjacent triangular hole segments 21.

[0033] like Figure 1 and Figure 2 As shown, the ends of the perforated holes 2 that are close to each other in the second direction are the triangular hole segments 21, the straight segments 212 are the two inclined sides of the triangular hole segments 21, and the curved segments 211 are formed at the intersection vertices of the two inclined sides of the triangular hole segments 21. The square hole segments 22 extend along the second direction. As the two straight segments 212 on the same perforated hole 2 extend towards the vertex of the curved segments 211, the width of the spacing portion 3 gradually increases. It is conceivable that the multiple perforated holes 2 can be hole segments formed by stamping. The square hole segments 22 extend along the second direction, and the shape of the square hole segments, in addition to square holes, can also be irregular holes, etc., provided that the easily foldable area is formed between the two straight segments 212.

[0034] The plate 1 can be bent to form an integral outer shell structure. The plate 1 includes a supporting shell portion 11 and a cover shell portion 12. A pre-folded section 4 is formed between the supporting shell portion 11 and the cover shell portion 12 so that the supporting shell portion 11 and the cover shell portion 12 are set at an angle. Part of the hollow hole 2 is provided in the pre-folded section 4.

[0035] The plate 1 can be configured as a straight plate structure, and when the entire plate 1 is bent, bending deformation can be formed at multiple easily bent areas. However, in actual operation, the deformation first occurs in the easily bent areas, so when the entire plate 1 is bent, the bending deformation formed at multiple hollow holes 2 often fails to form a relatively aesthetically pleasing bending arc.

[0036] Considering the above issues, a pre-folding section 4 is provided between the supporting shell portion 11 and the cover shell portion 12. The pre-folding section 4 is formed at the middle position of the plate body 1 in the second direction, that is, at the end connection of the supporting shell portion 11 and the cover shell portion 12. It should be noted that, as mentioned above, the plurality of hollow holes 2 are partially staggered in the second direction. In actual pre-folding, the pre-folding section 4 is formed at the plurality of hollow holes 2 at the end position of the supporting shell portion 11. The plurality of hollow holes 2 in this part are formed as follows: Figure 1 The pre-bending arc shown is preferably set to 90 degrees. During bending, force is applied from the end of the cover shell 12 away from the support shell 11. At this time, because multiple perforated holes 2 are provided at the end where the cover shell 12 and the support shell 11 meet, the strength of the plate 1 at the junction of the cover shell 12 and the pre-bending section 4 is relatively low. During actual bending, the plate 1 structure at this location will first undergo bending deformation, thus producing a bending arc corresponding to the pre-bending section 4. This, to a certain extent, ensures the aesthetics of the bent surface at the junction of the cover shell 12 and the support shell 11.

[0037] It is conceivable that the pre-folded segment 4 can also be a pre-bent structure formed on the cover shell portion 12. The pre-folded segment 4 can be formed by stamping to obtain the corresponding bending structure.

[0038] To ensure the effective engagement of the supporting shell portion 11 and the cover shell portion 12 after bending their separated ends, thus forming a relatively stable shell structure 100, the separated ends of the supporting shell portion 11 and the cover shell portion 12 are designated as engagement ends 5, and a fixing structure 51 is provided between the two engagement ends 5 for connection.

[0039] Specifically, the fixing structure 51 is configured as a snap-fit ​​structure 511, which includes a snap protrusion located on the end of the support shell portion 11 and a snap ring 512 located on the cover shell portion 12 and cooperating with the snap protrusion. At least two sets of the snap protrusion and the snap ring 512 are provided. It is conceivable that the fixing structure 51 could also be configured as a screw or pin, etc. However, the above-mentioned fixing structure 51 requires external structural operation for fixation. This is difficult to operate on miniature electronic structures, and welding is not convenient. In contrast, the snap-fit ​​structure 511 allows for detachable fixation, is convenient to operate, and has better reliability.

[0040] Furthermore, pre-bent structures are formed at the snap-fit ​​ends 5 of both the supporting shell portion 11 and the cover shell portion 12. The two pre-bent structures snap together to form a bending arc similar to that at the multiple hollow holes 2, which not only improves the shielding performance of the entire shell structure 100, but also further enhances the aesthetics of the entire shell structure 100.

[0041] To further ensure the stability of the support shell 11 and the cover shell 12 after they are fastened together, the fixing structure 51 also includes an axial limiting structure. The axial limiting structure includes a protrusion 513 and a recess 514 located on the two fastening ends 5 and cooperating with each other. The protrusion 513 and the recess 514 can be specifically configured as follows: Figure 1 The wavy end structure of the supporting shell 11 and the cover shell 12 engages with each other. When the engaging ends 5 of the supporting shell 11 and the cover shell 12 engage with each other, the protrusion 513 and the recessed part 514 engage with each other, thereby preventing relative sliding between the supporting shell 11 and the cover shell 12, and further ensuring the stability of the overall shell structure 100 formed by bending.

[0042] The housing structure 100 has a cavity for fixing electrical components. Specifically, a mounting portion 6 is provided on one end of the supporting housing portion 11 and / or the cover housing portion 12 corresponding to the cavity for fixing the electrical components. The mounting portion 6 includes a threaded hole 61 on the supporting housing portion 11 and / or the cover housing portion 12. When actually installing the electrical components, the corresponding electrical components can be installed into the cavity using screws. In addition, a plug-in portion 62 is provided on the supporting housing portion 11 and / or the cover housing portion 12 facing the cavity. The plug-in portion 62 can cooperate with the mounting hole structure on the electrical components to provide auxiliary limiting and fixing of the electrical components.

[0043] This utility model also includes an electronic product, such as Figure 1 and Figure 4As shown, the electronic product includes a housing structure 100 and circuit components 7. The specific details of the housing structure 100 are as described in the above embodiments. Because the housing structure 100 adopts all the technical solutions in the above embodiments, it possesses all the beneficial effects of the technical solutions in the above embodiments, and will not be repeated here. The circuit components 7 are mounted on the mounting portion 6 of the housing structure 100. The electrical components include, but are not limited to, circuit board structures.

[0044] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
