[0052] 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.

[0053] 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 and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0054] like Figures 1 to 15 As shown, this disclosure provides a mid-frame component 1, which can be used in electronic devices such as mobile phones and tablets.

[0055] like Figures 1 to 15 As shown, the middle frame assembly 1 of this embodiment may include a middle frame, which may include a substrate 10 and an outer frame 11 surrounding the substrate 10. The substrate 10 and the outer frame 11 may form a receiving cavity 12, which may be used to accommodate components such as circuit boards, power supplies, and wireless charging components. The outer frame 11 may provide support and protection. The outer frame 11 may be a ring structure, and its shape may be rectangular or other shapes. The outer frame 11 may extend along the edge of the substrate 10. Alternatively, the substrate 10 may include a plurality of plates distributed along a direction Y intersecting the thickness direction X of the substrate 10. Each plate is located within the area enclosed by the outer frame 11 and connected to the outer frame 11. The outer frame 11 may include an outer peripheral surface 111 and an inner peripheral surface 112, and a top surface 113 connecting the outer peripheral surface 111 and the inner peripheral surface 112. The substrate 10 may be connected to the inner peripheral surface 112 of the outer frame 11, and the top surface 113 of the outer frame 11 may be perpendicular to the thickness direction X of the substrate 10. The substrate 10 and the outer frame 11 can be made of metals or alloys with good thermal conductivity, such as copper, stainless steel, and aluminum alloy. The substrate 10 and the outer frame 11 can be integrally formed by processes such as stamping and casting, and no special restrictions are made here.

[0056] The middle frame assembly 1 may further include an inner frame 13, which may be disposed on the side of the outer frame 11 near the receiving cavity 12, and at least part of the inner frame 13 may cover the top surface 113 of the outer frame 11. The inner frame 13 may extend along a rectangular or other shaped trajectory and may be a continuous ring structure, which can serve both as support and protection, and can also cooperate with the outer frame 11 to form an antenna structure for signal radiation. The inner frame 13 may be made of non-metallic materials such as plastic, and the inner frame 13 may be formed by injection molding, stamping, or other processes, without special limitations. The inner frame 13 may be connected to the outer frame 11 to form an antenna structure. The outer frame 11 may be provided with multiple connecting holes 11c, and the inner frame 13 may be provided with multiple connecting posts 131. The multiple connecting holes 11c and the multiple connecting posts 131 correspond one-to-one, and each connecting post 131 can extend into its corresponding connecting hole 11c to connect the inner frame 13 and the outer frame 11. The connecting post 131 and the connecting hole 11c can be interference-fitted to improve the connection stability between the inner frame 13 and the outer frame 11.

[0057] The antenna structure can be a continuous ring structure or it can include multiple spaced antenna segments, i.e., the inner frame 13 and the outer shell can be segmented structures. Adjacent antenna segments can be separated by insulating strips. Different antenna segments can be used for communication in different frequency bands, and the same antenna segment can be used for communication in multiple frequency bands. Thus, multiple antenna segments can be used to achieve functions such as mobile communication, wireless local area network communication, and Bluetooth communication.

[0058] In some embodiments of this disclosure, such as Figure 2 , 14 As shown in Figure 15, the outer frame 11 may be provided with a first mounting hole 11a, which extends from the side of the outer frame 11 away from the receiving cavity 12 to the side of the outer frame 11 closer to the receiving cavity 12. That is, the first mounting hole 11a extends from the outer peripheral surface 111 of the outer frame 11 to the inner peripheral surface 112 of the outer frame 11. The first mounting hole 11a may be a through hole, which may penetrate the outer frame 11, or the first mounting hole 11a may not be a through hole, and its depth may be less than the thickness of the outer frame 11. The thickness of the outer frame 11 mentioned here refers to the distance between the outer peripheral surface 111 and the inner peripheral surface 112 of the outer frame 11. The projection shape of the first mounting hole 11a in the thickness direction of the outer frame 11 may be circular, or it may be other shapes such as rectangle, trapezoid, etc., without specific limitations.

[0059] like Figure 1 , 2 As shown in Figures 7 and 8, the mid-frame assembly 1 may further include a decorative assembly 2, at least a portion of which may be disposed within the first mounting hole 11a, to decorate the mid-frame assembly 1 and enhance its aesthetics. The decorative assembly 2 may include a support frame 23 and a decorative element 24, the support frame 23 being used to support the decorative element 24. The decorative element 24 may be a diamond, but is not limited thereto.

[0060] like Figure 2 , 7 As shown in Figures 8 and 11, the support frame 23 may have a mounting portion 231 and a limiting portion 21. The mounting portion 231 may include a mounting groove 231a, in which the decorative element 24 may be mounted. For example, the decorative element 24 may be mounted in the groove 231a by processes such as inlaying or bonding. The mounting portion 231 may also include a stop plate 2311, which may be disposed at the opening of the mounting groove 231a and connected to the inner wall of the mounting groove 231a. The stop plate 2311 may be configured to prevent the decorative element 24 from detaching from the mounting groove 231a, thereby improving the stability of the installation of the decorative element 24.

[0061] The stop plate 2311 can be a continuous annular structure extending along the inner wall of the mounting groove 231a to increase its stopping area for the decorative element 24, thereby further improving its stopping ability for the decorative element 24 and further improving the stability of the installation of the decorative element 24.

[0062] The stop plate 2311 can also be a structure that extends along part of the inner wall of the mounting groove 231a. This can reduce the material used to manufacture the stop plate 2311 while ensuring good stopping ability for the decorative part 24, thus saving on manufacturing costs. Multiple stop plates 2311 can also be provided, and these multiple stop plates 2311 can be spaced apart along the inner wall of the mounting groove 231a to improve their stopping ability for the decorative part 24.

[0063] The inner walls of the stop plate 2311 and the mounting groove 231a can be a one-piece structure, that is, the inner walls of the stop plate 2311 and the mounting groove 231a can be integrally formed by processes such as stamping and casting, without any special limitations. This can improve the connection strength between the inner walls of the stop plate 2311 and the mounting groove 231a, and reduce the probability of the stop plate 2311 breaking or falling off.

[0064] The inner walls of the stop plate 2311 and the mounting groove 231a can also be separate structures, that is, the inner walls of the stop plate 2311 and the mounting groove 231a can be manufactured separately, and then the stop plate 2311 can be connected to the inner wall of the mounting groove 231a by welding, bonding or other connection methods. This can reduce the manufacturing difficulty of the mounting part 231.

[0065] The mounting part 231 can be located on the side of the limiting member 3 away from the receiving cavity 12, so that the decorative part 24 mounted on the mounting part 231 is located on the outside of the outer frame 11, thereby further improving the aesthetics of the middle frame assembly 1.

[0066] like Figure 2 , 7As shown in Figures 8, 12, and 13, the middle frame assembly 1 may further include a limiting member 3, which can engage with the limiting part 21 to prevent the decorative component 2 from detaching from the first mounting hole 11a, thereby improving the stability of the decorative component 2 installation. The limiting member 3 can be disposed on the outer frame 11, allowing the limiting member 3 to be closer to the decorative component 2 disposed in the first mounting hole 11a of the outer frame 11, facilitating the limiting member 3 to engage with the limiting part 21.

[0067] In some embodiments of this disclosure, the outer peripheral surface 111 of the limiting portion 21 may be provided with a limiting groove 21a. The limiting groove 21a may be a straight slot extending in the thickness direction X of the substrate 10, or the limiting groove 21a may be an annular groove surrounding the outer peripheral surface 111 of the limiting portion 21. There are no specific limitations on this. The limiting member 3 may pass through the first mounting hole 11a, and at least a portion of the limiting member 3 may extend into the limiting groove 21a and engage with the limiting groove 21a for limiting.

[0068] The limiting member 3 can be detachably mounted on the outer frame 11 to facilitate the installation and removal of the decorative component 2. When the decorative component 2 needs to be installed on the outer frame 11, the limiting member 3 can be mounted on the outer frame 11 and inserted into the first mounting hole 11a, so that the limiting member 3 is in a limiting engagement with the limiting groove 21a. When the decorative component 2 needs to be removed from the outer frame 11, the limiting member 3 can be removed from the outer frame 11 to separate the limiting member 3 from the limiting groove 21a. At the same time, the limiting member 3 can be installed on the outer frame 11 again when the decorative component 2 extends into the first mounting hole 11a, so as to avoid the decorative component 2 being blocked by the limiting member 3 when extending into the first mounting hole 11a.

[0069] like Figures 2 to 8 As shown, the top surface 113 of the outer frame 11 may be provided with a second mounting hole 11b extending toward the substrate 10. The second mounting hole 11b may communicate with the first mounting hole 11a, and at least part of the limiting member 3 may be located within the second mounting hole 11b. This prevents the limiting member 3 from protruding or excessively protruding from the top surface 113 of the outer frame 11, facilitating the subsequent installation of other structural members on the top surface 113 of the outer frame 11.

[0070] like Figures 2 to 13 As shown, the limiting member 3 may include a mounting block 31 and a limiting plate 32. The mounting block 31 can be installed in the second mounting hole 11b, and the limiting plate 32 can be connected to the mounting block 31 so that the limiting plate 32 is installed in the second mounting hole 11b. The end of the limiting plate 32 away from the mounting block 31 can extend into the limiting groove 21a.

[0071] Part of the limiting plate 32 can be located inside the mounting block 31, which can improve the connection strength between the limiting plate 32 and the mounting block 31, reduce the probability of the limiting plate 32 and the mounting block 31 separating, thereby reducing the probability of limiting failure between the limiting plate 32 and the limiting part 21, and ensuring the limiting effect between the limiting plate 32 and the limiting part 21.

[0072] The portion of the limiting plate 32 located within the mounting block 31 may have a curved structure 321. For example, the entire portion of the limiting plate 32 within the mounting block 31 may be a curved structure 321, or the portion of the limiting plate 32 within the mounting block 31 may be composed of both a curved structure 321 and a straight structure 322. In this embodiment, by providing the curved structure 321, the contact area between the limiting plate 32 and the mounting block 31 can be increased, thereby further improving the connection strength between the limiting plate 32 and the mounting block 31. The portion of the limiting plate 32 located outside the mounting block 31 may be a straight structure 322 to facilitate the limiting plate 32 extending into the limiting groove 21a, but this is not the only possibility; the portion of the limiting plate 32 located outside the mounting block 31 may also have a curved structure 321.

[0073] The mounting block 31 may include a body portion 311 and an engaging portion 312. The body portion 311 may be connected to the limiting plate 32. The engaging portion 312 may be provided on the outer peripheral surface 111 of the body portion 311.

[0074] In some embodiments of this disclosure, such as Figure 4 and 7 As shown, the engaging part 312 can be interference-fitted with the inner wall of the second mounting hole 11b to improve the installation strength of the mounting block 31 in the second mounting hole 11b and facilitate the installation operation of the mounting block 31. At the same time, since the wall of the second mounting hole 11b is relatively thin, the interference fit method can avoid setting other fixing structures on the wall of the second mounting hole 11b, thereby reducing the manufacturing difficulty of the outer frame 11.

[0075] Furthermore, the engaging portion 312 may include a plurality of engaging blocks 3121, which may be spaced apart around the circumference of the body portion 311 to increase the position of the interference fit between the engaging portion 312 and the inner wall of the second mounting hole 11b, thereby further improving the installation strength of the mounting block 31 within the second mounting hole 11b. Simultaneously, by dividing the engaging portion 312 into a plurality of spaced-apart engaging blocks 3121, the weight of the engaging portion 312 can be reduced, thereby reducing the weight of the middle frame assembly 1.

[0076] In other embodiments of this disclosure, such as Figure 5 and 8As shown, the inner wall of the second mounting hole 11b can be provided with a locking groove 11d. The locking groove can be located at the opening of the second mounting hole 11b and extend towards the bottom wall of the second mounting hole 11b. The locking part 312 can be located in the locking groove 11d and engage with the locking groove 11d, so as to use the locking groove 11d to lock and fix the locking part 312, ensuring the installation strength of the mounting block 31 installed in the second mounting hole 11b. The locking groove 11d can also be used to position the locking part 312, ensuring the installation accuracy of the mounting block 31. At the same time, the locking groove 11d can also be used to limit the locking part 312, preventing the mounting block 31 from shaking.

[0077] The engaging portion 312 may include a plurality of engaging blocks 3121, which are spaced apart circumferentially on the body portion 311. Multiple engaging grooves 11d may be present, spaced apart circumferentially on the second mounting hole 11b. The multiple engaging blocks 3121 and the multiple engaging grooves 11d may correspond one-to-one, with each engaging block 3121 located within its corresponding engaging groove 11d and engaging with that groove 11d. By providing multiple engaging blocks 3121 and multiple engaging grooves 11d, the installation strength and accuracy of the mounting block 31 within the second mounting hole 11b can be improved, and further, shaking of the mounting block 31 can be prevented.

[0078] Furthermore, such as Figure 4 , 5 As shown in Figure 12, the bottom wall of the second mounting hole 11b may be provided with a positioning hole 115, and the mounting block 31 may also include a positioning post 313. The positioning post 313 may be provided on the side of the body part 311 near the bottom wall of the second mounting hole 11b, and part of the positioning post 313 may be located in the positioning hole 115 to position the limiting member 3 when it is installed in the second mounting hole 11b.

[0079] In some embodiments of this disclosure, such as Figures 2 to 5 As shown, the inner frame 13 covering the top surface 113 may be provided with a third mounting hole 13a extending toward the substrate 10. The third mounting hole 13a may communicate with the second mounting hole 11b. A portion of the limiting member 3 may be located in the third mounting hole 13a to effectively prevent the inner frame 13 from blocking the limiting member 3 and preventing the limiting member 3 from being installed in the second mounting hole 11b.

[0080] The width H1 of the limiting groove 21a in the thickness direction Z of the outer frame 11 can be greater than the width H2 of the limiting plate 32 in the thickness direction Z of the outer frame 11, so as to allow for a fit tolerance between the limiting groove 21a and the limiting plate 32, avoiding the problem that the limiting groove 21a and the limiting plate 32 cannot fit properly due to insufficient machining accuracy. The difference between the width H1 of the limiting groove 21a in the thickness direction Z of the outer frame 11 and the width H2 of the limiting plate 32 in the thickness direction Z of the outer frame 11 can be greater than or equal to 0.08mm, so as to ensure that there is sufficient fit tolerance between the limiting groove 21a and the limiting plate 32, and to ensure that the limiting groove 21a and the limiting plate 32 can fit properly.

[0081] Mounting block 31 can be made of non-metallic materials such as plastic to reduce the weight of limiting member 3. However, it is not limited to this; mounting block 31 can also be made of metal to improve its structural strength. Limiting member 3 can be made of metal such as aluminum or stainless steel to give it sufficient structural strength to block decorative component 2, but it is not limited to this; limiting member 3 can also be made of non-metallic materials.

[0082] In some embodiments of this disclosure, such as Figure 11 and 15 As shown, the outer frame 11 may include a positioning platform 114, which may be located within the first mounting hole 11a. The decorative component 2 may be provided with a positioning groove 22a, which may be, but is not limited to, provided on the support frame 23. The surface of the positioning groove 22a may fit against the surface of the positioning platform 114, so as to use the positioning groove 22a and the positioning platform 114 to position the outer frame 11 and the decorative component 2, while preventing the decorative component 2 from rotating within the first mounting hole 11a, thereby improving the installation stability of the decorative component 2.

[0083] like Figure 7 and 8 As shown, the middle frame assembly 1 may further include an adhesive layer 14. The adhesive layer 14 may be located at least between the decorative component 2 and the bottom wall of the first mounting hole 11a. For example, the adhesive layer 14 may be located between the support frame 23 and the bottom wall of the first mounting hole 11a to bond the decorative component 2 to the bottom wall of the first mounting hole 11a, which can further improve the installation stability of the decorative component 2. When installing the decorative component 2, glue may be applied to the bottom wall of the first mounting hole 11a to form the adhesive layer 14. The decorative component 2 may be inserted into the first mounting hole 11a and bonded to the adhesive layer 14. Then, the limiting member 3 may be inserted into the first mounting hole 11a, and at least a portion of the limiting member 3 may extend into the limiting groove 21a.

[0084] like Figures 2 to 10As shown, to facilitate the operator in inserting the limiting member 3 into the first mounting hole 11a and to ensure that at least a portion of the limiting member 3 extends into the limiting groove 21a, the inventors improved the structure of the limiting member 3 by adding a hand-held block. This hand-held block can be connected to the mounting block 31, and when the limiting member 3 extends into the limiting groove 21a, at least a portion of the hand-held block can protrude from the outer frame 11. Simultaneously, to prevent the hand-held portion 33 from protruding from the outer frame 11 and affecting the installation of other structural components, the inventors further improved the structure of the limiting member 3 by reducing the structural strength at the connection between the hand-held portion 33 and the mounting block 31. When the limiting member 3 extends into the limiting groove 21a, the operator can apply force to the hand-held portion 33, causing it to separate from the mounting block 31.
