Description

Technical Field

[0001] The present disclosure relates to the technical field of electronic equipment, and in particular to a shielding component and an electronic device. Background Art

[0002] Shielding components are crucial components in electronic devices, shielding internal circuits from the effects of external electromagnetic waves and preventing electromagnetic waves generated by internal circuits from radiating outward. As electronic devices become thinner and smaller, the integration of electronic components within them becomes increasingly dense, placing higher demands on the size of shielding components.

[0003] Currently, shielding components are generally thick, making it difficult to meet the requirements of thinner and lighter electronic devices. For example, a shielding component that uses copper foil for heat dissipation requires multiple components, including a shielding member, copper foil, and foam, making the stacked shielding component quite thick.

[0005] The present disclosure provides a shielding assembly, which is applied to an electronic device, and includes a base and a cover; the base includes a main body and a side wall bent relative to the main body toward a first direction; the main body and the side wall together form a receiving space for installing electronic components of the electronic device; the cover is located on the side of the base away from the receiving space; the cover includes a shielding portion and a connecting portion; the shielding portion abuts against the main body, and the connecting portion extends from the shielding portion toward the first direction and is arranged opposite to the side wall; the connecting portion includes a connecting surface facing the side wall, a protrusion is provided at the end of the connecting surface in the first direction, and the side wall is provided with a recess mounted to cooperate with the protrusion.

[0006] Furthermore, the side wall includes a first bottom edge facing the first direction, and the concave portion is formed by being recessed from the first bottom edge away from the first direction.

[0007] Furthermore, the recess includes a pair of inner walls and a connecting wall connecting the pair of inner walls, and the pair of inner walls are formed by extending from the first bottom edge away from the first direction and approaching each other.

DETAILED DESCRIPTION

[0023] Here, the technical solutions in the embodiments (or "implementations") of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0024] If there are terms related to directional indications or positional relationships in the embodiments of the present disclosure (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of the present disclosure are used only for descriptive convenience and should not be understood as indicating or implying relative importance.

[0025] Shielding assemblies are important components in electronic devices, shielding internal circuits from external electromagnetic waves and preventing electromagnetic waves generated by these circuits from radiating outward. Currently, shielding assemblies are large and cannot meet the requirements for thinner and lighter electronic devices. This disclosure provides a shielding assembly and electronic device to address related technical issues.

[0026] like Figure 1As shown, the present disclosure provides a shielding assembly for use in electronic devices, comprising a base 10 and a cover 20. The base 10 includes a main body 11 and a sidewall 12 bent relative to the main body 11. The main body 11 and the sidewall 12 together form a receiving space 100 for mounting electronic components of the electronic device. The cover 20 is located on a side of the base 10 facing away from the receiving space 100.

[0027] The cover 20 includes a shielding portion 21 and a connecting portion 22. The shielding portion 21 abuts the main body 11, and the connecting portion 22 extends from the shielding portion 21 in a first direction. The connecting portion 22 is disposed opposite the side wall 12. The connecting portion 22 includes a connecting surface 220 facing the side wall 12. A protrusion 23 is provided at the end of the connecting surface 220 in the first direction. The side wall 12 is provided with a recess 121 that mates with the protrusion 23.

[0028] By positioning the protrusion 23 at the end of the connection surface 220, the connection portion 22 only needs to extend to the position of the protrusion 23, eliminating the need to extend further from the protrusion 23 along the first direction. This reduces the size of the cover 20 in the first direction, thereby reducing the overall thickness of the shielding assembly. Furthermore, the mating protrusion 23 and recess 121 improve the efficiency of assembly and disassembly of the cover 20, facilitate subsequent maintenance, and reduce costs.

[0029] The present disclosure also provides an electronic device comprising a circuit board 30, an electronic component 40, and the aforementioned shielding assembly. A base 10 is assembled to one side of the circuit board 30, and the electronic component 40 is mounted to the circuit board 30 and positioned within a receiving space 100. Because the shielding assembly of the present disclosure has a relatively low thickness, the electronic device of the present disclosure has high space utilization and is more lightweight and thinner. Furthermore, because the cover 20 has a high assembly and disassembly efficiency, the electronic device can be repaired more efficiently and at a lower cost.

[0030] like Figure 1 As shown, the main body 11 and the side wall 12 may be plate-shaped. The base 10 may be integrally stamped to increase strength. In one embodiment, the base 10 may further include a flange 13. The flange 13 extends from the side wall 12 in a direction away from the receiving space 100. The flange 13 abuts against the circuit board 30. By providing the flange 13, the contact area between the base 10 and the circuit board 30 is increased, the installation strength of the shielding assembly is improved, and the stability of the electronic device is increased.

[0031] like Figure 2As shown, the sidewall 12 includes a first bottom edge 120 facing in a first direction. In one embodiment, a recess 121 may be formed by recessing from the first bottom edge 120 away from the first direction. The recess 121 is disposed at the bottom of the sidewall 12, forming a notched structure. This eliminates the need for a wall portion below the recess 121, reducing the overall thickness of the base 10 and further reducing the thickness of the shielding assembly.

[0032] In other embodiments, the recess 121 may also be located in the middle of the side wall 12, forming a hole structure. The recess 121 is surrounded by the wall of the side wall 12 to enhance the connection strength between the protrusion 23 and the recess 121, thereby increasing the installation strength of the shielding assembly.

[0033] In the embodiment where the concave portion 121 is formed by being recessed from the first bottom edge 120 away from the first direction, as shown in FIG. Figure 1 and Figure 2 As shown, the recess 121 may include a pair of inner walls 1211 and a connecting wall 1212 connecting the pair of inner walls 1211 . The pair of inner walls 1211 extend from the first bottom side 120 away from the first direction and are close to each other.

[0034] As the pair of inner walls 1211 extend closer together, the distance between them gradually decreases. On the one hand, the protrusion 23 can be easily installed into the recess 121 from a position where the pair of inner walls 1211 are farther apart, improving the assembly efficiency of the cover 20. On the other hand, the position where the pair of inner walls 1211 are closer together provides a higher clamping force, increasing the connection strength between the protrusion 23 and the recess 121, thereby enhancing the installation stability of the cover 20.

[0035] The specific structural form of the recess 121 is not limited and can be in the shape of a "convex" character or a triangle. In other embodiments, the pair of inner walls 1211 can also be arranged in parallel to reduce manufacturing difficulty. For example, the recess 121 can be rectangular.

[0036] In embodiments where the base 10 includes a flange 13, as shown Figure 1 and Figure 2 As shown, in the direction of flange 13 extension, recess 121 can pass through sidewall 12 and flange 13. By passing recess 121 through flange 13, protrusion 23 can be assembled to sidewall 12 through flange 13. Compared to installing protrusion 23 to sidewall 12 from above flange 13, passing protrusion 23 through flange 13 allows protrusion 23 to be closer to circuit board 30, thereby further reducing the space occupied by the shielding assembly.

[0037] like Figure 1 and Figure 3As shown, the shielding portion 21 can be plate-shaped and mounted over the base 10 to provide shielding. Heat dissipating silicone grease can be applied to the shielding portion 21 to dissipate heat from the electronic components 40. The connecting portion 22 can be plate-shaped, and multiple connecting portions 22 can be provided, surrounding the base 10 to enhance shielding effectiveness. In other embodiments, the specific structural forms of the shielding portion 21 and the connecting portion 22 are not limited.

[0038] In one embodiment, if Figure 3 As shown, the connecting portion 22 may include a plate 221 and a lug 222. The plate 221 extends from the shielding portion 21 toward the first direction. The plate 221 includes a second bottom edge 2211 facing the first direction, and the lug 222 protrudes from the second bottom edge 2211. The protrusion 23 is provided on the lug 222.

[0039] By providing the lugs 222, the area of the protrusion 23 formed is increased, thereby enhancing the forming strength of the protrusion 23 and improving the installation stability of the shielding assembly. The protrusion 23 can be formed by any method, including stamping. Furthermore, the second bottom edge 2211 does not need to extend entirely along the first direction, reducing the amount of material required to manufacture the cover 20 and lowering the weight of the shielding assembly to meet lightweight requirements. In other embodiments, the connecting portion 22 may be rectangular. The specific structural form of the connecting portion 22 is not limited.

[0040] The lug 222 may include a pair of side edges 2221 and a connecting edge 2222 connecting the pair of side edges 2221. The pair of side edges 2221 may extend from the second base edge 2211 toward the first direction. The lug 222 and the second base edge 2211 have a large connection area, which can enhance the structural strength of the lug 222 and further improve the installation stability of the shielding assembly. Furthermore, the lug 222 gradually narrows in the first direction, reducing weight and achieving lightweight design.

[0041] In this embodiment, if Figure 3 As shown, the connecting edge 2222 can be parallel to the second bottom edge 2211. The lug 222 is in an inverted trapezoidal shape, which can reduce the extended length of the pair of side edges 2221, thereby further reducing the dimension of the cover 20 in the first direction and reducing the thickness of the shielding assembly. In other embodiments, the specific structural form of the lug 222 is not limited and can be an inverted triangle, rectangle, etc.

[0042] The number of lugs 222 can be multiple, and the multiple lugs 222 are spaced apart on the second bottom edge 2211. Providing multiple lugs 222 can improve the connection strength between the cover 20 and the base 10, thereby improving the installation stability of the shielding assembly. The number and distribution of the lugs 222 are not limited.

[0043] For example, when the connecting portion 22 is disposed along the length of the electronic device, the multiple lugs 222 are also disposed along the length of the electronic device on the second bottom edge 2211. When the connecting portion 22 is disposed along the width of the electronic device, the multiple lugs 222 are also disposed along the width of the electronic device on the second bottom edge 2211. When the connecting portion 22 is disposed obliquely relative to the length and width of the electronic device, the multiple lugs 222 are also disposed at intervals along the oblique direction on the second bottom edge 2211.

[0044] like Figure 4 As shown, the receiving space 100 may include a first portion 101 and a second portion 102. In a first direction, the thickness of the first portion 101 is greater than the thickness of the second portion 102. The shielding assembly disclosed herein can meet the installation requirements of electronic components 40 of different sizes.

[0045] Specifically, in one embodiment, Figure 4 As shown, the electronic component 40 includes a first electronic component 41 and a second electronic component 42. In a first direction, the thickness of the first electronic component 41 is greater than that of the second electronic component 42. The first electronic component 41 is installed in the first portion 101, and the second electronic component 42 is installed in the second portion 102.

[0046] In this embodiment, the protrusions 23 may include a first protrusion 231 and a second protrusion 232. On the connecting portion 22 near the first portion 101, since the connecting portion 22 there is thicker, the first protrusion 231 may be positioned in the middle of the connecting portion 22 to enhance the structural strength of the first protrusion 231. On the connecting portion 22 near the second portion 102, to meet the dimensional requirement of reducing the thickness, the second protrusion 232 may be positioned at the end of the connecting portion 22 there. In other embodiments, the protrusions 23 may be positioned at both ends of the connecting portion 22.

[0047] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this disclosure is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this disclosure shall be included in the scope of protection of this disclosure.
