[0004] This application provides a protective structure for a camera module and an electronic device.

[0005] The first aspect of this application provides a protective structure for a camera module, including:

[0006] Ceramic components, including a protective surface and a mounting surface that are positioned opposite each other;

[0007] A first connector includes a first end and a second end, the first end extending into the ceramic component and the second end extending out of the mounting surface; the first connector is integrally formed with the ceramic component.

[0008] The second connector is used to fix the ceramic part by cooperating with the second end of the first connector.

[0009] In some embodiments, at least the portion of the first connector that is connected to the ceramic component is made of stainless steel; the ceramic component is in the form of ceramic powder and comes into contact with the stainless steel portion of the first connector to form a film and sinter, thereby achieving integral molding of the first connector and the ceramic component.

[0010] In some embodiments, the first connector includes a main body portion, one end of which extends out of the ceramic component for engaging with the second connector, and the sidewall of the end of the main body portion located inside the ceramic component extends outward to form a protrusion.

[0011] In some embodiments, the height of the main body is 1.6mm to 2.2mm; the distance between the end of the main body located inside the ceramic part and the mounting surface is 0.2mm to 0.6mm.

[0012] In some embodiments, the main body is cylindrical and the protrusion is annular; the diameter of the main body is 1.4mm to 1.8mm and the diameter of the protrusion is 1.8mm to 2.2mm.

[0013] In some embodiments, the mounting surface of the ceramic component is provided with a reinforcing portion, which is integrally formed with the ceramic component; the reinforcing portion surrounds the portion of the first connector that extends out of the mounting surface and is fitted with the side wall of the first connector.

[0014] In some embodiments, the thickness of the reinforcing portion is 0.1 mm to 0.2 mm.

[0015] In some embodiments, the height of the end face of the reinforcing portion away from the mounting surface is less than or equal to the height of the second end of the first connector from the mounting surface.

[0016] In some embodiments, one of the first connector and the second connector is a nut and the other is a bolt.

[0017] In some embodiments, when the first connector is a nut, a sealing portion is provided at the first end of the nut, and the sealing portion seals the internal thread hole of the nut.

[0034] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0035] If the embodiments of this application contain terms relating to directional indications or positional relationships (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 relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0036] The protective structure and electronic device of the camera module according to embodiments of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can complement or combine with each other.

[0037] This application provides a protective structure for a camera module, such as... Figures 1 to 3 As shown, the protective structure 100 includes a ceramic component 10, a first connector 20, and a second connector 30. The ceramic component 10 includes a protective surface 101 and a mounting surface 102 disposed opposite to each other. The first connector 20 includes a first end 201 and a second end 202. The first end 201 of the first connector 20 extends into the ceramic component 10, and the second end 202 extends out of the mounting surface 102. The first connector 20 is integrally formed with the ceramic component 10. The second connector 30 is used to cooperate with the second end 202 of the first connector 20 to fix the ceramic component 10.

[0038] The ceramic part 10 is used to cover and protect the camera module. The protective surface 101 of the ceramic part 10 faces outward and can withstand external impact and friction. The mounting surface 102 of the ceramic part 10 faces the camera module and is fixedly connected to other structures (such as housings, brackets, etc.) through the first connector 20 and the second connector 30.

[0039] The first connector 20 and the ceramic part 10 are integrally formed, meaning that at least a portion of the first connector 20 is embedded within the ceramic part 10 to form an integrated structure. For example, ceramic powder can be used to surround the first end 201 of the first connector 20 before sintering. After sintering, the ceramic powder becomes dense and tightly bonded to the first connector 20. Therefore, in this application, the ceramic part 10 and the first connector 20 are integrally formed, eliminating the need for adhesives or other fixation methods. This avoids structural failure caused by adhesive aging or mechanical impact, and improves the strength and reliability of the protective structure.

[0040] In one embodiment, at least the portion of the first connector 20 connected to the ceramic part 10 is made of stainless steel. The ceramic part 10, in the form of ceramic powder, contacts the stainless steel portion of the first connector 20 and forms a film for sintering, thereby achieving integral molding of the first connector 20 and the ceramic part 10. The sintering temperature range of the ceramic powder is 700℃~1000℃, and the melting temperature of stainless steel is 1400℃. Thus, the temperature difference can be used to sinter the ceramic part 10 and the first connector 20 into one piece.

[0041] Specifically, when the first connector 20 and the ceramic part 10 are integrally formed, a mold for forming the ceramic part 10 can be provided first, and the mold has a preset space inside for accommodating the first connector 20. The first connector 20 is placed into the preset space of the mold, and ceramic powder is filled into the mold, ensuring that the ceramic powder at least surrounds the first end 201 of the first connector 20. Pressure is applied to the mold to compact the ceramic powder and form a blank, followed by high-temperature sintering treatment, finally forming an integrated structure of the first connector 20 and the ceramic part 10.

[0042] In one embodiment, such as Figures 2 to 4 As shown, the first connector 20 includes a main body 21. One end of the main body 21, located within the ceramic component 10, extends outward to form a protrusion 22. The end of the main body 21 extending out of the ceramic component 10 is used to engage with the second connector 30. That is, the first end 201 of the first connector 20 forms the protrusion 22, and the second end 202 engages with the second connector 30. When the first connector 20 is subjected to external force, the force is mainly distributed along the axial direction of the main body 21. When the protrusion 22 is covered by ceramic material, it engages with the ceramic component 10, preventing the first connector 20 from moving along its axial direction. This enhances the connection strength between the protrusion 22 and the ceramic component 10, preventing the first connector 20 from detaching from the ceramic component 10 when subjected to significant external force.

[0043] In one embodiment, such as Figure 3 and Figure 4 As shown, the height 'a' of the main body 21 is 1.6mm to 2.2mm. This height is also the height of the first connector 20, specifically the height between the first end 201 and the second end 202. This arrangement ensures that the main body 21 has sufficient height to fit with the second connector 30 while avoiding excessive space occupation. In some embodiments, the height 'a' of the main body 21 can be, for example, 1.8mm, 1.9mm, 2.0mm, 2.1mm, etc.

[0044] In one embodiment, the distance b between the end of the main body 21 located inside the ceramic part 10 and the mounting surface is 0.2mm to 0.6mm, that is, the depth to which the first end 201 of the first connector 20 extends into the ceramic part 10 is 0.2mm to 0.6mm. This arrangement ensures that the first connector 20 has sufficient embedding depth to be fixed to the ceramic part 10. In some embodiments, the distance b between the end of the main body 21 located inside the ceramic part 10 and the mounting surface can be, for example, 0.3mm, 0.4mm, 0.5mm, etc.

[0045] In one embodiment, such as Figure 3 and Figure 4 As shown, the main body 21 is cylindrical, and the protrusion 22 is annular. Both the cylindrical and annular shapes are standard geometric shapes, which are easy to manufacture by stamping, turning, etc. The annular protrusion 22 can also increase the contact area between the first connector 20 and the ceramic part 10, and provide stress support in all directions, avoiding local stress concentration that could cause the first connector 20 to separate from the ceramic part 10.

[0046] In one embodiment, such as Figure 3 As shown, the diameter c of the main body 21 is 1.4mm to 1.8mm, and the diameter c of the main body 21 can be, for example, 1.5mm, 1.6mm, 1.7mm, etc.

[0047] In one embodiment, such as Figure 3 As shown, the diameter d of the protrusion 22 is 1.8mm to 2.2mm, and the diameter d of the protrusion 22 can be, for example, 1.9mm, 2.0mm, 2.1mm, etc.

[0048] In one embodiment, such as Figure 2 As shown, the mounting surface 102 of the ceramic component 10 is provided with a reinforcing portion 11, which is integrally formed with the ceramic component 10. The reinforcing portion 11 surrounds the portion of the first connector 20 that extends out of the mounting surface 102 and fits against the side wall of the first connector 20. The reinforcing portion 11 not only enhances the bonding strength between the ceramic component 10 and the first connector 20, but also improves the impact resistance, assembly stability, and sealing performance of the protective structure.

[0049] exist Figure 2 In the illustrated embodiment, the portion of the main body 21 of the first connector 20 extending out of the mounting surface 102 is fitted with the reinforcing portion 11. During the manufacturing process, the preset space in the mold used to form the ceramic part 10 is slightly larger than the diameter of the main body 21. After the first connector 20 is placed into the preset space, ceramic powder is filled into the mold, and the ceramic powder enters between the main body 21 and the inner wall of the preset space. After the ceramic powder is fired at high temperature, the aforementioned reinforcing portion 11 is formed.

[0050] In one embodiment, such as Figure 3 As shown, the thickness e of the reinforcing part 11 is 0.1 mm to 0.2 mm. The thickness e of the reinforcing part 11 can be, for example, 0.12 mm, 0.15 mm, 0.18 mm, etc.

[0051] In one embodiment, such as Figure 2 and Figure 3 As shown, the height of the end face of the reinforcing part 11 away from the mounting surface 102 is less than or equal to the height of the second end 202 of the first connector 20 from the mounting surface 102. Since the material of the reinforcing part 11 is ceramic, when the reinforcing part 11 is lower than the second end 202, it can not only play a role in structural reinforcement, but also prevent the reinforcing part 11 from breaking under the action of external force when it exceeds the second end 202.

[0052] In one embodiment, such as Figure 2 and Figure 3 As shown, the first connecting member 20 is a nut, and the second connecting member 30 is a bolt. The threaded connection of the nut and bolt provides high tensile and shear resistance, and the two are easy to assemble. In some other embodiments, the first connecting member 20 can be a bolt, and the second connecting member 30 can be a nut.

[0053] In one embodiment, such as Figure 2 As shown, when the first connector 20 is a nut, the first end 201 of the nut is provided with a sealing part 23, which seals the internal thread hole of the nut. During the manufacturing process, after the nut is placed into the preset space in the mold, ceramic powder is then filled into the mold. The sealing part 23 can prevent the ceramic powder from entering the internal thread hole of the nut and blocking the thread, ensuring that the function of the nut is not affected.

[0054] This application also provides an electronic device, such as... Figures 5 to 7 As shown, the electronic device includes a housing 200, a camera module, and the aforementioned protective structure 100.

[0055] The housing 200 can protect the camera module and other components inside the electronic device. For example... Figure 5 and Figure 8 As shown, the housing 200 includes a first plate 40 and a second plate 50. The first plate 40 includes a cutout portion 41. The cutout portion 41 can provide accommodating space for the installation of the second plate 50 and the camera module.

[0056] like Figure 9 and Figure 10 As shown, the ceramic component 10 also includes a first abutment portion 12 disposed around the mounting surface 102, the first abutment portion 12 being located on the side of the first plate 40. The second plate 50 includes a second abutment portion 51, the second abutment portion 51 being located on the side of the first plate 40 away from the first abutment portion 12.

[0057] The second connector 30 passes through the second plate 50 and the hollow part and connects with the first connector 20, clamping the first plate 40 between the first abutment 12 and the second abutment 51. The camera module is located on the side of the second plate 50 away from the ceramic part 10.

[0058] The ceramic component 10 of the protective structure 100 has high hardness and wear resistance, effectively resisting friction, scratches, and impacts during daily use. The ceramic component also has a smooth and delicate surface texture, which can enhance the aesthetics of the fairy device.

[0059] In one embodiment, such as Figure 5 and Figure 6 As shown, the ceramic part 10 is provided with a first camera hole 13 that penetrates the mounting surface and the protective surface, and the second plate 50 is provided with a second camera hole 52 that penetrates both sides of the second plate 50 and is provided in correspondence with the first camera hole 13. The camera of the camera module can take pictures through the first camera hole 13 and the second camera hole 52.

[0060] In one embodiment, the electronic device may be a product such as a computer, mobile phone, or wearable display device.

[0061] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application 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 application should be included within the scope of protection of this application.
