[0022] Those skilled in the art will recognize and understand that, according to common practice, the various features of the drawings discussed below are not necessarily drawn to scale and that the sizes of the various features and elements of the drawings may be exaggerated or reduced in order to more clearly illustrate the embodiments of the invention described herein. DETAILED DESCRIPTION

[0023] Reference will now be made specifically to the representative embodiments shown in the accompanying drawings. It should be understood that the following description is not intended to limit the embodiments to a preferred embodiment. On the contrary, it is intended to cover alternatives, modifications and equivalent forms that may be included in the spirit and scope of the embodiments defined by the appended claims.

[0024] In the following detailed description, reference is made to the accompanying drawings which form a part of the specification and in which are shown by way of illustration specific embodiments in accordance with the described embodiments. Although these embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments, it is to be understood that these examples are not limiting and that other embodiments may be used and changes may be made without departing from the spirit and scope of the described embodiments.

[0025] Recent technological advances and increased consumer demand have prompted manufacturers to include additional operating components (e.g., front camera, rear camera, antenna, etc.) into the small cavity of the housing. However, due to the delicate nature of the assembly process, these operating components are prone to misalignment when the portable electronic device is subjected to a drop event. Unfortunately, misalignment of these operating components often causes them to fail prematurely. The embodiments described herein generally relate to support structures for fixing operating components in portable electronic devices. Specifically, these support structures can still maintain the operating components in a known alignment and position even after the portable electronic device is subjected to a drop event.

[0026] To address the aforementioned deficiencies, the systems and techniques described herein relate to support structures, such as back walls, trim structures, support structures, and weld washers, that can minimize damage and / or misalignment of these operating components.

[0027] According to some embodiments, a portable electronic device is described. The portable electronic device includes a housing member defining an external side wall, a first glass cover, and a second glass cover, wherein the second glass cover includes: a first area having a first outer surface; a second area having a second outer surface vertically displaced relative to the first outer surface, wherein the second area includes a first opening, a second opening, and a third opening; and a transition area having an outer surface extending between the first outer surface and the second outer surface. The portable electronic device also includes a first camera module disposed in the first opening, a second camera module disposed in the second opening, a strobe light module disposed in the third opening, and a trimming structure having an edge of the second area covering the second glass cover.

[0028] Refer to Figure 1- Fig.12 These and other embodiments are discussed. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these drawings is for illustrative purposes only and should not be construed as limiting.

[0029] Figure 1A-1B A front isometric view and a rear isometric view of a portable electronic device according to some embodiments are shown. The portable electronic device described herein includes various support structures capable of supporting operating components in a cavity of a housing of the portable electronic device. According to some examples, the portable electronic device is a computing device, a smart phone, a laptop, a smart watch, a fitness tracker, a mobile phone, a wearable consumer device, etc. The housing of the portable electronic device may also be referred to as a shell. It should be noted that the support structures described herein can be used to fix operating components to prevent these operating components from becoming displaced or misaligned when the portable electronic device 100 is subjected to a load event (e.g., a drop event).

[0030] Figure 1AA front isometric view of a portable electronic device 100 is shown, wherein the portable electronic device 100 includes a housing 102 having a wall defining a cavity, wherein an operating component is carried in the cavity. The housing 102 may also be referred to as a housing member. The housing 102 includes a top wall 102-A, a bottom wall 102-B, and a side wall 102-C. The top wall 102-A, the bottom wall 102-B, and the side wall 102-C may define a metal band around the periphery of the housing 102 and define the cavity. The top wall 102-A, the bottom wall 102-B, and the side wall 102-C may have a curved cross section. In addition, the top wall 102-A, the bottom wall 102-B, and the side wall 102-C may include a front edge that supports a protective cover 106.

[0031] The portable electronic device 100 includes a display assembly 104 that substantially covers the entire top surface of the portable electronic device 100. The display assembly 104 may include a capacitive unit and / or a force detection unit that is capable of detecting input at the display assembly 104 and presenting a corresponding graphical output at the display assembly 104. In some embodiments, the display assembly 104 is covered by a protective cover 106, wherein the protective cover 106 is secured with a trim structure 108. Specifically, the trim structure 108 may be joined to the housing 102 using an attachment structure such as an adhesive, a weld, or the like. The protective cover 106 may prevent surface wear and scratches from damaging the display assembly 104. The protective cover 106 may be formed of a transparent material such as glass, plastic, sapphire, or the like.

[0032] In some embodiments, the top wall 102-A may be separated from the bottom wall 102-B by a partition having an insulating material 112, and the side wall 102-C may be separated from the top wall 102-A and the bottom wall 102-B by a partition having an insulating material 112. The insulating material 112 may include plastic, injection molded plastic, polyethylene terephthalate ("PET"), polyetheretherketone ("PEEK"), ceramic, etc. By incorporating the insulating material 112, the walls 102-A, 102-B, and 102-C are electrically isolated from each other.

[0033] According to some embodiments, the portable electronic device 100 includes a switch 116 carried along one of the side walls 102-C. The bottom wall 102-B includes a data connector 120 capable of providing data and / or power to the portable electronic device 100. In some examples, the connector 120 refers to a bus and power connector. The connector 120 is electrically coupled to an internal power supply (not shown) carried within the cavity. The bottom wall 102-B includes a speaker opening 122 to transmit sound output generated by a speaker module carried within the portable electronic device 100.

[0034] According to some embodiments, the portable electronic device 100 includes a first electronic component 131 and a second electronic component 132. These electronic components 131 and 132 can be used for facial recognition. In some examples, the electronic components 131 and 132 include cameras, infrared light (IR) detectors, IR light transmitters, etc. The IR light detector and the IR light transmitter can verify the user for the portable electronic device 100. The first electronic component 131 and the second electronic component 132 can be carried in a recess 134 in the protective cover 106. The recess 134 has a circular shape or a polygonal shape (e.g., a trapezoidal, rectangular, square, etc.). The recess 134 can be shorter, taller, wider, rounder, and any common shape, as long as the shape is sufficient to allow the first electronic component 131 and the second electronic component 132 to provide functions. The shape and size of the recess 134 is a design choice.

[0035] According to some examples, housing 102 includes a combination of metal materials and non-metal materials. At least one of top wall 102-A, bottom wall 102-B or side wall 102-C may be formed of metal materials (e.g., anodized aluminum, titanium, stainless steel, etc.). In some examples, top wall 102-A, bottom wall 102-B and side wall 102-C may also refer to a metal band around the periphery of portable electronic device 100. Top wall 102-A, bottom wall 102-B and side wall 102-C may have beveled edges. Top wall 102-A, bottom wall 102-B and side wall 102-C jointly define a side surface with a spline profile. According to some examples, at least one of top wall 102-A, bottom wall 102-B or side wall 102-C is formed of non-metal materials. According to some examples, non-metal materials include glass, plastic, ceramics, etc. Advantageously, using non-metallic materials can reduce the amount of electromagnetic interference associated with housing 102 and a wireless transceiver carried within housing 102. Additionally, using non-metallic materials reduces the amount of parasitic capacitance between housing 102 and any metallic support structures carried within the cavity.

[0036] According to some embodiments, the portable electronic device 100 carries one or more operating components within a cavity of the portable electronic device 100. These operating components may include circuit boards, antennas, multi-core processors, tactile feedback modules, cameras, strobe light modules, sensors, IR detectors, inductive charging coils, etc.

[0037] Figure 1BA rear isometric view of a portable electronic device 100 according to some embodiments is shown. The housing 102 may be secured to a rear wall 130, wherein the rear wall 130 is secured to the housing 102. In some examples, the rear wall 130 is formed of a non-metallic material (e.g., glass, plastic) to facilitate the passage of an electromagnetic field through the rear wall 130 to reach and charge a wireless charging coil 142 carried within the cavity. In some examples, a trimming structure 108 is secured to the rear wall 130. Additionally, the rear wall 130 may cover the wireless antenna 150-A, the wireless antenna 150-B, and the wireless antenna 150-C. In some examples, because the rear wall 130 is formed of a non-metallic material, radio frequency (RF) signals generated and / or received by the wireless antenna 150-A, the wireless antenna 150-B, and the wireless antenna 150-C may pass through the rear wall 130 with little or no interference. The rear wall 130 may be made of an RF transparent material. Although Figure 1B Not shown, the portable electronic device 100 includes a support plate having holes aligned with the positions of the wireless antennas 150-A, 150-B, and 150-C. In some examples, the rear wall 130 may be referred to as a second protective cover, and the protective cover 106 may be referred to as a first protective cover. In some examples, the rear wall 130 may be referred to as a rear protective cover, and the protective cover 106 may be referred to as a front protective cover. The first protective cover and the second protective cover may be coupled to the side wall 102-C. In addition, the side wall 102-C and at least one of the first protective cover or the second protective cover may define a cavity of the portable electronic device 100.

[0038] According to some embodiments, the portable electronic device 100 includes a camera assembly 160 carried at a corner portion of the portable electronic device 100. The camera assembly 160 may be carried in a boss 170 of the rear wall 130. Specifically, the rear wall 130 and the boss 170 may be formed as a single piece of non-metallic material (e.g., glass). In other words, the boss 170 and the rear wall 130 are a seamless piece of material. The boss 170 is raised relative to the remaining portion of the rear wall 130. Figure 1B As shown in , the remaining portion of the rear wall 130 has a first thickness, and the boss 170 has a second thickness greater than the first thickness. In some examples, the remaining portion of the rear wall 130 corresponds to the first portion of the rear wall 130, and the boss 170 corresponds to the second portion of the rear wall 130. The rear wall 130 can be characterized as a curved shape. In some examples, the rear wall 130 has a textured surface. In some examples, the rear wall 130 includes a combination of different textures. For example, the boss 170 may have a smooth surface, while the remaining portion of the rear wall 130 has a textured surface. As described herein, the textured surface may correspond to peaks separated by valleys. In addition, the peaks may correspond to positive vertical deviations relative to the nominal surface, and the valleys may correspond to negative vertical deviations relative to the nominal surface.

[0039] The camera assembly 160 includes three camera modules, such as camera module 162-A, camera module 162-B, and camera module 162-C. In some examples, camera module 162-A, camera module 162-B, and camera module 162-C represent a telephoto lens, a wide-angle lens, and an ultra-wide-angle lens, respectively. However, it should be noted that the positions of the telephoto lens, the wide-angle lens, and the ultra-wide-angle lens are interchangeable in all openings described herein. In addition, the camera assembly 160 includes a strobe light module 164 (or camera flash). The strobe light module 164 may include one or more light-emitting diodes. The boss 170 may include a cutout or opening in the material for each of the camera modules 162-A, camera modules 162-B, camera modules 162-C, and strobe light modules 164. Certain portions of the camera modules 162-A, camera modules 162-B, camera modules 162-C, and strobe light modules 164 may be configured to pass through the openings in the thickness of the boss 170. Additionally, in some examples, boss 170 carries microphone 166. Boss 170 may similarly include an opening for microphone 166. In some examples, each of camera modules 162-A, 162-B, and 162-C may include a camera turret having an outer surface that protrudes relative to an outer surface of boss 170. Advantageously, the use of boss 170 facilitates visual aspects, wherein camera modules 162-A, 162-B, and 162-C are shown as a single element. It should be noted that any number of camera modules may be incorporated into a camera assembly carried by boss 170.

[0040] The camera modules 162-A, 162-B, and 162-C of the camera assembly 160 may be arranged in a triangle, such as Figure 1B As shown. In some examples, camera modules 162-A, 162-B, and 162-C of camera assembly 160 may also be arranged in a satellite manner, such as a circular orbit. Camera modules 162-A, 162-B, and 162-C are not equidistantly spaced from strobe light module 164; however, camera modules 162-A, 162-B, and 162-C may be equidistant from each other. It should be understood by those of ordinary skill in the art that when a strobe light module emits a flash, the flash may cause a red-eye effect, which is caused by the reddening of the pupils in a color photograph of a subject, and the reddening of the pupils is caused by the flash being too close to the camera module.

[0041] In some examples, camera module 162-A is referred to as a telephoto lens, camera module 162-B is referred to as a wide angle lens, and camera module 162-C is referred to as an ultra wide angle lens. Because a wide angle lens (e.g., camera module 162-B) is more likely to be utilized when taking a photo of a subject with portable electronic device 100, other camera modules (e.g., camera module 162-A, camera module 162-C) are calibrated relative to camera module 162-B. Calibration of these camera modules 162-A, camera module 162-B, and camera module 162-C is more challenging because the triangular orientation results in calibration for multiple directions (X-axis, Y-axis). In addition, such calibration is more challenging than when the camera modules are arranged in a linear orientation.

[0042] Figure 2 A rear isometric view of a portable electronic device 200 is shown in accordance with some embodiments. Portable electronic device 200 is similar to portable electronic device 100, except that a camera assembly 260 of portable electronic device 200 includes two camera modules, such as camera module 162-A and camera module 162-B.

[0043] Camera assembly 260 is carried within boss 170 of rear wall 130. Notably, boss 170 of camera assembly 160 and camera assembly 260 have similar sizes and shapes. However, camera assembly 260 includes fewer camera modules. Advantageously, making boss 170 the same size between different embodiments of the camera assembly reduces manufacturing and material costs associated with producing different models of portable electronic devices (e.g., portable electronic device 100, portable electronic device 200). Figure 1B As shown, the boss 170 and the rear wall 130 of the portable electronic device 200 can be formed as one piece of non-metallic material (e.g., glass). In other words, the boss 170 and the rear wall 130 are a seamless piece of material. The boss 170 is raised relative to the remaining portion of the rear wall 130. The boss 170 includes openings for the strobe light module 164 and the microphone module 166. In other embodiments, it can be pointed out that the boss 170 is formed separately from the rear wall 130, and they are formed of different materials. For example, the boss 170 can be formed of metal and the rear wall 130 can be formed of glass or plastic. The metal can be bonded to the glass or plastic.

[0044] Figure 3A-3H Various perspective views of a portable electronic device according to some embodiments are shown. It should be noted that one or more features of the housing (e.g., material, shape, switch, etc.) may be different from those of the embodiment shown in FIG. Figure 3A-3H The portable electronic devices are shared among each other.

[0045] Figure 3AA perspective view of a portable electronic device 300-A according to some embodiments is shown. In some embodiments, the portable electronic device 300-A corresponds to the portable electronic device 100, such as Figure 1A-1B As shown. Portable electronic device 300-A includes a housing having a top wall 302-A, a bottom wall, and a side wall 302-B, wherein the side wall forms a metal band structure around the periphery of portable electronic device 300-A. The metal band structure may be formed of anodized aluminum, titanium, or stainless steel. The metal band structure may include a dielectric band 312, which isolates top wall 302-A from side wall 302-B. The outer surface of dielectric band 312 may be flush with the outer surface of top wall 302-A, bottom wall 302-C, and side wall 302-B. Dielectric band 312 may match the color of top wall, bottom wall, and side wall. Side wall 302-B includes a slide switch 316, which enables portable electronic device 300-A to transition between a ringing state and a silent state. Slide switch 316 can slide between an off state and an on state. When slide switch 316 is aligned with rocker switch 314 and rocker switch 318, the ringing is turned on. Rocker switches 314, 318 can respectively increase and decrease the system volume of portable electronic device 300-A.

[0046] Portable electronic device 300-A includes a rear wall 330 having a first thickness. Rear wall 330 can be characterized as having a flat surface. Raised portion 370 is formed integrally with rear wall 330 so that rear wall 330 and raised portion 370 are seamlessly connected. In other words, rear wall 330 can be formed by machining to remove material of rear wall 330. Raised portion 370 may be parallel to some parts of rear wall 330 and not parallel to other parts of rear wall 330. Raised portion 370 has a second thickness greater than the first thickness of rear wall 330. Rear wall 330 may be formed of RF transparent material (e.g., glass, etc.) to allow RF signals to pass through rear wall 330 to reach a wireless antenna carried by portable electronic device 300-A. In some examples, rear wall 330 is formed of colored glass. Colored glass may have a matte or frosted surface finish, which is defined as a texture along the surface of rear wall 330. In addition, the raised portion 370 can be formed of colored glass that matches the color of the colored glass of the rear wall 330. In some examples, the rear wall 330 and / or the raised portion 370 are visually transparent, allowing almost all visible light incident on the outer surface of the rear wall 330 to pass through. In some examples, the rear wall 330 can impart a frosted or matte appearance to the surface due to diffuse reflection of visible light incident on the surface. In addition, the rear wall 330 is transparent to electromagnetic field signals and allows the electromagnetic field to pass through the rear wall 330 to reach the wireless charging coil (e.g., the wireless charging coil 142).

[0047] The portable electronic device 300-A includes a rear wall 330 having a corner portion 306. Adjacent and near the corner portion 306 (e.g., a distance of less than 3 cm) is a raised portion 370 of the rear wall 330. However, the raised portion 370 may also be positioned near the top wall 302-A or the bottom wall of the portable electronic device 300-A. Similar to the rear wall 330, the raised portion 370 also includes an RF transparent material and an EMF transparent material (e.g., glass, etc.). In some examples, the raised portion 370 is approximately 0.2 mm to 2 mm away from the outer surface of the rear wall 330. However, it should be noted that the height of the outer surface of the raised portion 370 relative to the outer surface of the rear wall 330 can be any height as long as the height does not affect the operation and function of the camera module, the strobe light module, and the microphone module partially carried by the raised portion 370. The transition edge 372 separates the rear wall 330 from the raised portion 370, and the transition edge 372 bridges the drop between the thickness of the rear wall 330 and the thickness of the raised portion 370. In some examples, the transition edge 372 has an average thickness that is less than the thickness of the raised portion 370. In some examples, the transition edge 372 has a curved profile that is chamfered or rounded (e.g., concave). The face of the transition edge 372 is not parallel to the outer surface of the rear wall 330 and the raised portion 370. In addition, design aesthetics with different heights along the transition edge 372 can also be envisioned. The transition edge 372 can all have a consistent thickness, forming an infinite loop. The transition edge 372 can have a non-uniform thickness. In some examples, the outer surface of the raised portion 370 has a textured surface or a smooth polished surface. The outer surfaces of the rear wall 330, the transition edge 372, and the raised portion 370 can have any combination of the aforementioned surface finishes, as long as the combination does not affect the operation and function of the camera module, the strobe flash module, and the microphone module. In some examples, the surface finish can include a frosted surface appearance. The textured surface or the smooth polished surface of the outer surface of the rear wall 330, the transition edge 372, and the raised portion 370 can be formed by at least one of a chemical etching or a mechanical etching process.

[0048] The raised portion 370 has a polygonal shape with rounded corners 374. The rounded corners 374 are raised relative to the outer surface of the rear wall 330. The rounded corners 374 can be curved along a transition edge 372 disposed between the raised portion 370 and the rear wall 330. In other examples, the transition edge 372 is a straight edge instead of a curved edge. The transition edge 372 has a curved surface. It should be noted that any surface shape along the transition edge 372 can be implemented as a design choice as long as it does not affect the operation and function of the camera module, strobe light module, and microphone module that are partially carried by the raised portion 370. Although Figure 3AThe raised portion 370 is shown as being completely adjoined by the transition edge 372 , but it should also be noted that the raised portion 370 may only be partially adjoined by the transition edge 372 .

[0049] The raised portion 370 includes a plurality of openings for a camera module, a strobe light module, and a microphone module. Figure 3A As shown, the raised portion 370 includes a first camera opening 350-A, a second camera opening 350-B, a third camera opening 350-C, a strobe light opening, and a microphone opening. These openings are formed by machining through the entire thickness of the raised portion 370. Disposed in the first camera opening 350-A is a first camera module 360-A, disposed in the second camera opening 350-B is a second camera module 360-B, and disposed in the third camera opening 350-C is a third camera module 360-C. Each of the camera modules 360-A, 360-B, and 360-C may include a camera base that carries a lens element. The lens element may be centered relative to the camera base. For example, Figure 3A The center of the first lens element 366-A is shown to be centered relative to the camera base of the first camera module 360-A, the center of the second lens element 366-B is centered relative to the camera base of the second camera module 360-B, and the center of the third lens element 366-C is centered relative to the camera base of the third camera module 360-C. It should be understood by those of ordinary skill in the art that the lens elements 366-A, 366-B, and 366-C of the camera modules 360-A, 360-B, and 360-C are calibrated based on their positional relationship to each other. In other words, the positioning of the centers of the lens elements 366-A, 366-B, and 366-C may not be random. In some examples, the centers of the first camera module 360-A and the second camera module 360-B are along the same axis relative to each other, and the axis is parallel to the sidewall 302-B.

[0050] Figure 3AEach of the camera modules 360-A, 360-B, and 360-C is shown to include a turret window covering a lens element 366-A, a lens element 366-B, and a lens element 366-C. The first turret window 364-A covers the lens element 366-A, the second turret window 364-B covers the lens element 366-B, and the third turret window 364-C covers the lens element 366-C. In some examples, the outer surfaces of the first turret window 364-A, the second turret window 364-B, and the third turret window 364-C are coplanar with the outer surface of the raised portion 370. In other examples, the outer surfaces of the first turret window 364-A, the second turret window 364-B, and the third turret window 364-C are convex or concave relative to the outer surface of the raised portion 370. In some instances, the first turntable window 364-A, the second turntable window 364-B, and the third turntable window 364-C may be recessed relative to or coplanar with the outer surface of the raised portion 370 to prevent the turntable windows from being scratched when the rear surface of the portable electronic device 300-A slides on a rough surface.

[0051] Figure 3B A top view of a portable electronic device 300-A is shown according to some embodiments. Figure 3B The elevated portion 370 is shown to have a generally polygonal shape with curved / rounded edges. In some examples, the elevated portion 370 may have a shape corresponding to a circle, an oval, a rectangle, a trapezoid, a polygon, or a square, as long as such shapes do not affect the operation and functionality of the camera module, the strobe flash module, and the microphone module. The shape of the elevated portion 370 may be a design choice, Figure 3B The shapes shown should not be considered limiting of other possibilities.

[0052] Figure 3B The center of the first lens element 366-A is shown to be equidistantly spaced from the center of the second lens element 366-B and the center of the third lens element 366-C. In practice, Figure 3B A first lens element 366-A, a second lens element 366-B, and a third lens element 366-C are shown arranged according to a triangular orientation. In some examples, the first lens element 366-A, the second lens element 366-B, and the third lens element 366-C are arranged in an equilateral triangle orientation. The elevated portion includes a strobe light opening 380 for a strobe light module 382 and a microphone opening 384 for a microphone module 386. The center of the strobe light opening 380 and the center of the microphone opening 384 can be set to be unequally spaced from the first camera module 360-A, the second camera module 360-B, and the third camera module 360-C. Although Figure 3BThe strobe module 382 is shown disposed closer to the top wall 302-A and above the microphone module 386, but it should be noted that the positions of these modules may also be switched. In some examples, the center of the third camera module 360-C, the center of the strobe module 382, ​​and the center of the microphone module 386 are along the same axis relative to each other, and the axis is parallel to the side wall 302-B. In some examples, the center of the third camera opening 350-C, the center of the strobe opening 380, and the center of the microphone opening 384 are along the same axis relative to each other, and the axis is parallel to the side wall 302-B. The third camera opening 350-C may be larger than the strobe opening 380, and the strobe opening 380 may be larger than the microphone opening 384.

[0053] Figure 3B The raised portion 370 is shown disposed adjacent to the corner 306 of the portable electronic device 300-A. However, it should be noted that the raised portion 370 may also be disposed along the center of the rear wall 370, along the midline of the rear wall 370, or asymmetrically relative to the midline of the rear wall 370.

[0054] Figure 3C A perspective view of a portable electronic device 300-C according to some embodiments is shown. In some embodiments, the portable electronic device 300-C corresponds to the portable electronic device 200, such as Figure 2 As shown. The housing of the top wall 302-A, the bottom wall, and the side wall 302-B may be shared with the portable electronic device 300-C. However, the raised portion 370 of the rear wall 330 includes two camera modules, such as a first camera module 360-A and a second camera module 360-B. The raised portion 370 is raised relative to the outer surface of the rear wall 330. The raised portion 370 may be relatively Figure 3C Taller, wider, thicker, shorter, longer or more slender as shown.

[0055] Figure 3D A top view of a portable electronic device 300-C is shown according to some embodiments. As described above, the elevated portion includes two camera modules, such as a first camera module 360-A and a second camera module 360-B. Strobe light module 382 can be equidistant from the center of first lens element 366-A and the center of second lens element 366-B. Additionally, microphone module 386 can be positioned above strobe light module 382 (i.e., microphone module 386 is positioned closer to top wall 302-A).

[0056] Figure 3E According to some embodiments, a cross section DD (see Figure 3D) is a cross-sectional view of the portable electronic device 300-C. However, it should be noted that this cross-sectional view is also applicable to the portable electronic device 300-A. Figure 3E As shown, the top wall 302-A is electrically isolated from the side wall 302-B via the dielectric strip 312. The outer surface of the dielectric strip 312 may be flush with the outer surface of the top wall 302-A and the side wall 302-B. The top wall 302-A and the side wall 302-B are fixed to the trim structure that carries the protective cover 304 along the front surface of the portable electronic device 300-A. On the opposite rear surface of the portable electronic device 300-A is the rear wall 330. The rear wall 330 transitions to the elevated portion 370 along the transition edge 372. The first camera module 360-A and the second camera module 360-B are disposed in the elevated portion 370. The transition edge 372 may have a curved profile or a curved surface. The elevated portion 370 has a flat outer surface covered by the first trim structure 322-A, 322-B. The first trim structure 322-A, 322-B has an outer surface that covers certain portions of the elevated portion 370. In addition, the second trimming structures 324-A, 324-B have outer surfaces that protrude relative to the outer surfaces of the first trimming structures 322-A, 322-B. The first trimming structures 322-A, 322-B may have a uniform height or a non-uniform height. The second trimming structures 324-A, 324-B may have a uniform height or a non-uniform height.

[0057] Figure 3F-3H A top view of a portable electronic device according to some embodiments is shown. Figure 3F A top view of a portable electronic device 300-F is shown having a rear wall 330 including a raised portion 370. The raised portion 370 has a circular shape. Additionally, the strobe light opening 380 and the microphone opening 384 have circular openings. Additionally, Figure 3F The first camera opening 350-A, the second camera opening 350-B and the third camera opening 350-C are shown to be oriented in an L shape, which is defined as the second camera opening 350-B and the third camera opening 350-C are separated by a first distance, and the first camera opening 350-A and the second camera opening 350-B are separated by a second distance, wherein the first distance is less than the second distance. Figure 3F The first camera module 360-A and the second camera module 360-B are shown aligned with each other, and the second camera module 360-B and the third camera module 360-C are shown aligned with each other. Figure 3G A top view of a portable electronic device 300-G is shown having a rear wall 330 including an elevated portion 370. The elevated portion 370 has a curved trapezoidal shape. In addition, the strobe light opening 380 and the microphone opening 384 have polygonal openings and curved shaped openings. Figure 3HA top view of a portable electronic device 300-H is shown having a first camera module 360-A, a second camera module 360-B, and a third camera module 360-C oriented in a triangular orientation such that the first camera module 360-A and the third camera module 360-C are aligned along the same axis parallel to the top wall 302-A. Additionally, a microphone module 386 and a strobe light module 382 are disposed on opposite sides of the second camera module 360-B.

[0058] It should be pointed out that regarding Figures 3A-3H The sizes, features, and shapes described in any of the illustrated embodiments are merely representative of the many design possibilities that enable the camera modules, strobe light modules, and microphone modules to function as intended. The openings of the camera modules 360-A, 360-B, 360-C, strobe light modules 382, ​​and microphone modules 386 can be any combination of various shapes such as rectangular, square, circular, triangular, and the like. In one example, the first camera opening 350-A is circular and the second camera opening 350-B is polygonal. In another example, the first camera opening 350-A is circular and the second camera opening 350-B and the third camera opening 350-C are rectangular. In addition, the first opening, the second opening, and the third opening for the camera modules 360-A, 360-B, and 360-C can be oriented in an L-shaped orientation, a triangular orientation, a circular orientation, or any other orientation. It should also be noted that the positioning of the camera modules 360-A, 360-B, and 360-C within the first opening 350-A, the second opening 350-B, and the third opening 350-C are interchangeable. For example, the first camera module 360-A may be positioned in the second opening 350-B, the second camera module 360-B may be positioned in the third opening 350-C, and the third camera module 360-C may be positioned in the first opening 350-A. In addition, the positioning of the first camera module 360-A and the second camera module 360-B may be interchanged relative to the first opening 350-A and the second opening 350-B. For example, the position of the telephoto lens may be interchanged with the position of the wide-angle lens.

[0059] Figure 4An exploded perspective view of a portable electronic device 400 according to some embodiments is shown. The portable electronic device includes a housing 402 having a top wall 402-A, a bottom wall 402-B, and a side wall 402-C coupled together. The top wall 402-A, the bottom wall 402-B, and the side wall 402-C define a cavity 410 capable of carrying operating components therein. In addition, the side wall 402-C includes a metal strip 404 disposed along the periphery of the portable electronic device 400. The metal strip 404 is coupled to a rear wall 430. The rear wall 430 can be a transparent protective layer adhered or welded to the metal strip 404. The non-metallic material enables RF signals and electromagnetic fields to pass through the rear wall 430. In addition, the rear wall includes a boss 432 (or raised portion) relative to the remainder of the rear wall 430. Boss 432 includes openings 408-A, 408-B, and 408-C for camera turrets 416-A, 416-B, and 416-C, respectively. Camera turrets 416-A, 416-B, and 416-C include glass windows. Boss 432 also includes openings 460, 470 for a strobe light module and a microphone (not shown).

[0060] Metal strip 404 is coupled to support plate 450. Support plate 450 is capable of carrying electronic components (e.g., a main logic board, an auxiliary logic board, etc.). However, support plate 450 also includes multiple openings for one or more wireless antennas 452 and camera modules 410-A, 410-B, and 410-C, wherein camera modules 410-A, 410-B, and 410-C are configured to pass through the thickness of support plate 450. In some examples, wireless antenna 452 is an ultra-wideband antenna. For example, support plate 450 includes opening 428-C aligned with opening 408-C and camera module 410-C. It is worth noting that camera modules 410-A, 410-B, and 410-C are configured to pass through the thickness of support plate 450. Support plate 450 also includes a hole 480 for a wireless charging coil. Specifically, the electromagnetic field can pass through hole 480 in support plate 450 to reach the wireless charging coil. The holes 480 may correspond to areas where the support plate 450 is completely cut away / removed.

[0061] Camera modules 410-A, 410-B, and 410-C are carried by support structure 434. Support structure 434 includes respective brackets and springs for aligning each of camera modules 410-A, 410-B, and 410-C with predetermined positions (e.g., aligned with openings 408-A, 408-B, and 408-C). Once camera modules 410-A, 410-B, and 410-C are secured and aligned within the brackets of support structure 434, support structure 434 is mounted on top of the base of support plate 450. Support structure 434 can be adjusted to have different degrees of stiffness to provide an optimal load distribution path when portable electronic device 100, portable electronic device 200 is subjected to a drop event. Additionally, the support plates 450, support structures 434, and trim structures described herein may be adjusted to selectively direct loads away from the operating components and toward the housing, which is generally formed of a unibody construction and thus has greater rigidity to withstand stresses associated with the loads.

[0062] Figure 5A-Figure 5B Various cross-sectional views of a portable electronic device according to some embodiments are shown. Specifically, Figure 5A Shown along Figure 1B 500-A is a cross-sectional view of a camera assembly taken at the AA cross section of the portable electronic device 100 in FIG. The portable electronic device 100 includes a housing defined by side walls 502 and a rear wall 530. Specifically, the side walls 502 include a metal band 504 secured to the rear wall 530. In some instances, the metal band 504 is secured to the rear wall 530 via at least one of an adhesive, a fastener, or a weld. The side walls 502 carry a trim structure (not shown) that supports a protective cover 504. In some examples, the protective cover 504 covers the display assembly. The rear wall 530 may also be referred to as a rear protective cover.

[0063] The rear wall 530 is formed of a transparent material (e.g., glass) and includes an elevated portion (or boss). It is noteworthy that the rear wall 530 includes a first portion 532-A and a second portion 532-B elevated relative to the first portion 532-A. The first portion 532-A has a first thickness (T1), and the second portion 532-B has a second thickness (T2) greater than the first thickness (T1). In some examples, the second thickness (T2) is more than 1-3 times the first thickness (T1). In some examples, the first thickness is 0.7 mm and the second thickness is 1.5 mm. The second portion 532-B is elevated relative to the first portion 532-A via a transition portion 532-T. The transition portion 532-T is curved, but may also present an angle according to the design aesthetic requirements of the portable electronic device 100. In some examples, the outer surface of the second portion 532-B is parallel to or not parallel to the outer surface of the first portion 532-A. In some examples, the rear wall 530 may be characterized as having a spline shape. The first portion 532-A may be curved or wavy.

[0064] like Figure 5A As shown, the portable electronic device 100 includes a first camera module 510-A and a second camera module 510-B. It is noteworthy that the first camera module 510-A and the second camera module 510-B have a thickness that exceeds the thickness of the side wall 502. Therefore, the first camera module 510-A and the second camera module 510-B protrude and exceed the distal end (or bottom surface) of the side wall 502. However, the second portion 532-B of the rear wall 530 has a thickness sufficient to hide the first camera module 510-A and the second camera module 510-B within the cavity 506 of the portable electronic device 100. Specifically, the side wall 502 and the second portion 532-B of the rear wall 530 have a combined thickness that exceeds the thickness of the first camera module 510-A and the second camera module 510-B.

[0065] According to some embodiments, the first camera module 510-A and the second camera module 510-B are carried by the base 528. In some examples, the base 528 is formed of stainless steel, titanium, or other metals sufficient to prevent and / or minimize bending during prolonged use of the portable electronic device 100. Specifically, since the portable electronic device 100 is prone to drop events, the base 528 has sufficient rigidity to prevent the first camera module 510-A and the second camera module 510-B from becoming misaligned relative to each other. As previously described, the camera modules can be calibrated relative to each other. In addition, the first camera module 510-A and the second camera module 510-B are fixed using a base insert 527. It is worth noting that the base insert 527 has a low linear coefficient of thermal expansion (CTE) to prevent and / or minimize the expansion of the base 528 when the portable electronic device 100 is heated. Advantageously, this low CTE can also prevent and / or minimize the misalignment of the first camera module 510-A and the second camera module 510-B when heated. Additionally, first camera module 510-A and second camera module 510-B are epoxy-bonded to base 528 and base insert 527. In some examples, base insert 527 is formed of a high elastic modulus material (LCP) to minimize deflection / misalignment caused by static forces when first camera module 510-A and second camera module 510-B are assembled into portable electronic device 100. In some examples, base insert 527 has a higher stiffness than epoxy.

[0066] The first camera module 510-A includes a lens element 514-A, a lens barrel 516-A, and a turntable 512-A that accommodates the lens element 514-A and the lens barrel 516-A. The second camera module 510-B includes a lens element 514-B, a lens barrel 516-B, and a turntable 512-B that accommodates the lens element 514-B and the lens barrel 516-B. The first camera module 510-A and the second camera module 510-B are fixed to a predetermined alignment state and position using a support structure 534. Specifically, the first camera module 510-A and the second camera module 510-B are supported by the support structure 534. The support structure 534 can be fixed to the surface of the rear wall 530 via an adhesive.

[0067] According to some embodiments, the portable electronic device 100 includes a first trimming structure 522 (also referred to as an external trimming structure) and a second trimming structure 524 (also referred to as an internal trimming structure). The first trimming structure 522 and the second trimming structure 524 are welded to each other to form a trimming structure assembly and installed into the cavity 506 as a unit. When installed, the first trimming structure 522 includes an overhang having an outer surface that covers at least a portion of the second portion 532-B of the rear wall 530 (when the portable electronic device 100 is viewed with the rear wall 530 facing upward). Specifically, the first trimming structure 522 is assembled to abut against the second portion 532-B. The second trimming structure 524 is also assembled to abut against the first trimming structure 522. The second trimming structure 524 has an outer surface that protrudes relative to the outer surface of the overhang of the first trimming structure 522. Specifically, the outer surface may be coated with a diamond-like carbon (DLC) coating that prevents wear marks from affecting the visual appearance of the second trimming structure 524, while the outer surface of the first trimming structure 522 is coated with a metal coating (e.g., anodized aluminum, etc.) or is coated with a color to match the color of the sidewall 502. In some examples, the first trimming structure 522 is formed of anodized aluminum. The second trimming structure 525 may be formed of stainless steel. Advantageously, because the DLC coating is more wear-resistant than the metal coating, the outer surface of the second trimming structure 524 is protruding relative to the outer surface of the housing, thereby minimizing and / or eliminating wear marks on the outer surface of the housing, such as when the portable electronic device 100 is moved on a flat surface or object. In some examples, the DLC coating is 5-10 times more wear-resistant than the metal coating. In addition, the DLC coating may have a black appearance to disguise the presence of the first camera module 510-A and the second camera module 510-B, and to minimize stray light reflections on the first camera module 510-A and the second camera module 510-B.

[0068] According to some embodiments, the first trim structure 522 and the second trim structure 524 are sealed with O-rings 526. In some examples, a plurality of O-rings 526 are disposed across any interface between the back wall 530 and the first trim structure 522 and the second trim structure 524 to prevent moisture from entering the cavity 506. The support structure 534 can be secured to the first trim structure 522 and the second trim structure 524 via weld washers (not shown), as described with reference to FIG. Figure 7A-7B In some embodiments, the outer surfaces of turntable 512-A and turntable 512-B are coplanar with the outer surface of second trimming structure 524. It should be noted that portable electronic device 100 may utilize a single trimming structure or multiple trimming structures. In addition, Figure 5AA set of second trim structures 524 are shown disposed at opposite ends of the raised portion (e.g., raised portion 370) of the rear wall 530. These second trim structures 524 attach the first camera module 510-A and the second camera module 510-B. In addition, these second trim structures 524 may have an outer surface with a uniform height that is protruding relative to the outer surface of the overhang of the first trim structure 522.

[0069] Specifically, Figure 5B Shown along Figure 1B 500-B is a cross-sectional view of a camera assembly taken at a BB cross-section of a portable electronic device 100 in FIG. 500-B. The portable electronic device 100 includes a housing defined by side walls 502 and a rear wall 530. Specifically, the side walls 502 include a metal band 504 secured to the rear wall 530. In some instances, the metal band 504 is secured to the rear wall 530 via at least one of an adhesive, a fastener, or a weld. The side walls 502 carry a trim structure (not shown) that supports a protective cover 504. In some examples, the protective cover 504 covers the display assembly.

[0070] and Figure 5A Unlike the AA cross-section of the camera assembly 160 of the portable electronic device 100 shown in FIG, the BB cross-section of the camera assembly 160 shows a single camera module. Figure 5B A cross-sectional view 500-B of the camera assembly 160 including a third camera module 510-C is shown. The third camera module 510-C includes a lens element 514-C, a lens barrel 516-C, and a turntable 512-C that accommodates the lens element 514-C and the lens barrel 516-C. The third camera module 510-C is aligned in a triangular orientation relative to the first camera module 510-A and the second camera module 510-B. The third camera module 510-C is biased to a predetermined position using a support structure 534.

[0071] In addition, cross-sectional view 500-B shows a strobe light module 570 disposed as an opening through the thickness of the second portion 532-B of the rear wall 530. In some examples, the opening 572 is formed in the second portion 532-B. The strobe light module 570 is disposed in the opening 572. When the portable electronic device 100 is viewed with the protective cover 504 facing upward, the IR emitter and detection module 580 covers the strobe light module 570. The IR emitter and detection module 580 can be carried by the support plate 550. The opening 572 can have a circular hole defined by opposite edges of the second portion 532-B of the rear wall 530. The strobe light module 570 is sealed relative to the opposite edges by an O-ring 526. The support structure 534 includes an opening for the strobe light module 570 that is aligned with the opening 572 in the second portion 532-B. When installed, when the portable electronic device 100 is viewed with the protective cover 504 facing upward, the strobe light module 570 is covered by the support plate 550 and the support structure 534. Since the IR emitter and detection module 580 is positioned above the strobe light module 570, the strobe light module 570 cannot be too large in the Z direction. Advantageously, the boss of the rear wall 530 enables the strobe light module 570 and the IR emitter and detection module 580 to be assembled along the same Z direction.

[0072] In addition, cross-sectional view 500-B shows microphone module 560 carried within cavity 506. Microphone module 560 includes a detection component 562 that is arranged to pass through the thickness of second portion 532-B of rear wall 530. Second portion 532-B includes an opening 574 for detection component 562. In some examples, support structure 534 carries microphone 560 in a predetermined position. Support structure 534 includes an opening for microphone module 560 that is aligned with opening 574 in second portion 532-B.

[0073] Figure 6A-6B A cross-sectional view of a portable electronic device according to some embodiments is shown. Specifically, Fig. 6A Shown along Figure 2 A cross-sectional view 600 of the portable electronic device 200 taken at a CC cross section in FIG. Figure 5A-Figure 5B As shown, the portable electronic device 200 includes a housing defined by a rear wall 630 and side walls. Specifically, the side walls include a metal band fixed to the rear wall 630. In some examples, the metal band is fixed to the rear wall 630 via at least one of an adhesive, a fastener, or a weld. Figure 6B The portable electronic device 200 is shown to include a rear wall 630 having a first portion 632-A and a second portion 632-B that is elevated relative to the first portion 632-A. Fig. 6AAs shown, the portable electronic device 200 includes a first camera module 610 -A and a second camera module 610 -B. The first camera module 610 -A and the second camera module 610 -B are supported by a support structure 634 .

[0074] The first camera module 610-A includes a lens element 614-A and a lens barrel 616-A. The second camera module 610-B includes a lens element 614-B and a lens barrel 616-B. The first camera module 610-A and the second camera module 610-B are coupled to a mount 628. Advantageously, the mount 628 holds the first camera module 610-A and the second camera module 610-B toward the strobe flash module 164.

[0075] According to some embodiments, the first camera module 610-A and the second camera module 610-B are carried by a base 628. The base 628 is formed of stainless steel, titanium, or other metals sufficient to prevent and / or minimize bending during prolonged use of the portable electronic device 200. In addition, the first camera module 610-A and the second camera module 610-B are fixed using a base insert 625. It is worth noting that the base insert 625 has a low linear coefficient of thermal expansion (CTE) to prevent and / or minimize expansion of the base 628 when the portable electronic device 200 is heated. Advantageously, such a low CTE can also prevent and / or minimize misalignment of the first camera module 610-A and the second camera module 610-B when heated. In addition, the first camera module 610-A and the second camera module 610-B are bonded to the base 628 and the base insert 625 with epoxy resin. In some examples, the base insert 625 is formed of a high elastic modulus material (LCP). Using a high elastic modulus material can minimize deflection / misalignment caused by static forces when the first camera module 610 -A and the second camera module 610 -B are assembled into the portable electronic device 200 . Fig. 6A The combination of epoxy and base insert 625 is shown to achieve a near orthogonal alignment between the normals of first camera module 610 -A and second camera module 610 -B and protective cover 604 of portable electronic device 200 .

[0076] like Figure 6BAs shown, the portable electronic device 200 includes a first trimming structure 622 and a second trimming structure 624 sealed with an O-ring 626. The first trimming structure 622 and the second trimming structure 624 are installed between the rear wall 630 and the first camera module 610-A. The rear wall 630 may also be referred to as a protective cover or a glass cover. It should be noted that in other embodiments, the portable electronic device 200 may only include a single trimming structure (e.g., only the first trimming structure 622) installed between the rear wall 630 and the first camera module 610-A. It is worth noting that the rear wall 630 includes a first portion 632-A and a second portion 632-B raised relative to the first portion 632-A. The first portion 632-A has a first thickness, and the second portion 632-B has a second thickness greater than the first thickness. The support structure 634 can be fixed to the first trimming structure 622 and the second trimming structure 624 via a welding washer (not shown).

[0077] Figure 7A-7B Various perspective views of a portable electronic device according to some embodiments are shown. Figure 7A-7B As described in more detail, the use of welding washers allows different types of trim structures to be implemented into the housing of portable electronic devices 100, 200. In effect, welding washers allow different combinations of trim structures to be mounted relative to a rear wall (e.g., rear wall 130) while allowing for assembly tolerances.

[0078] Fig. 7A A perspective cross-sectional view 700-A of a portable electronic device 100 according to some embodiments is shown. The portable electronic device 100 includes a housing defined by side walls 702 and a rear wall 730. The side walls 702 and the rear wall 730 together define a cavity capable of carrying operating components therein. The side walls 702 include a metal strip 704, wherein the metal strip 704 is fixed to the rear wall 730 via at least one of an adhesive, a fastener, or a weld. The side walls 702 include a trimming structure that carries a protective cover 708. The protective cover 708 covers a display assembly 706. The display assembly 706 includes a thin film such as a light emitting diode (LED) layer.

[0079] As previously described herein, the rear wall 730 includes a first portion 732-A and a second portion 732-B. The second portion 732-B is elevated relative to the first portion 732-A such that the second portion 732-B has a second thickness (T2) greater than the first thickness (T1) of the first portion 732-A.

[0080] The portable electronic device 100 includes a camera module 710 disposed in the cavity. The camera module 710 includes a lens barrel 716 and a turntable 712. The camera module 710 is supported by a support structure 734. Fig. 7AAs shown, the support structure 734 has an L shape. Notably, the L shape enables the welding washer to fit within the opening defined by the L shape. In some examples, the welding washer is sized to fit within the thickness of the L shape.

[0081] The portable electronic device 100 includes a strobe light module 770. The strobe light module 770 is supported by a strobe light cover 774. The strobe light cover 774 includes a cover weld nut 740 to secure the strobe light cover 774 to the support structure 734. Fig. 7A As shown, the strobe light module 770 is mounted to pass through an opening 772 disposed between opposite edges of the second portion 732-B. The first trim structure 722 has an overhang covering a portion of the second portion 732-B (when viewing the portable electronic device 100 with the rear wall 730 facing upward). The second trim structure 724 has an outer surface that protrudes relative to the outer surface of the overhang of the first trim structure 722 (when viewing the portable electronic device 100 with the rear wall 730 facing upward). The first trim structure 722 and the second trim structure 724 are welded together and sealed and isolated from each other by an O-ring 726.

[0082] like Fig. 7A As shown, the IR emitter and detection module 780 covers the strobe light module 770 (when viewing the portable electronic device 100 with the protective cover 708 facing upward). In addition, the IR emitter and detection module 780 is supported by the support plate 750.

[0083] like Fig. 7A As shown, the turntable 712 of the camera module 710 protrudes slightly relative to the second portion 732-B (also referred to as the boss) of the rear wall 730. The first trimming structure 722 and the second trimming structure 724 help to accommodate the size of the camera module 710. It should be noted that without the boss of the rear wall 730, the portable electronic device 100 would require one or more trimming structures that are much taller in order to accommodate the camera module. The taller one or more trimming structures will make the portable electronic device heavier and thicker. In contrast, implementing a boss with a thicker rear wall 730 in multiple portions of the portable electronic device 100 that carry electronic components (e.g., a camera module, a strobe light module, etc.) enables the use of smaller trimming structures. In fact, it should be understood by those of ordinary skill in the art that taller trimming structures are more complicated to manufacture and assemble relative to other supporting structures of the portable electronic device.

[0084] Figure 7BA perspective cross-sectional view 700-B of a portable electronic device 100 is shown according to some embodiments. The portable electronic device 100 includes a camera module 710 having a lens barrel 716 and a turntable 712. The turntable 712 is secured in place using a first trim structure 722 and a second trim structure 724. The second trim structure 724 is secured to a portion of the turntable 712 via an adhesive 744. Additionally, the first trim structure 722 and the second trim structure 724 are sealed relative to each other and to a second portion 732-B of the rear wall 730 via an O-ring 726.

[0085] Figure 7B The support plate 750 is shown adhered to the surface of the second portion 732-B of the rear wall 730. Covering the support plate 750 is the support structure 734. Adjacent to the support structure 734 is a welding washer 742. Notably, the thickness of the welding washer 742 is less than the thickness of the support structure 734. During the manufacturing process, the first trimming structure 722 and the second trimming structure 724 are installed together. The support structure 734 is then assembled within the cavity of the portable electronic device 100 and joined to the first trimming structure 722 and the second trimming structure 724. Subsequently, the second trimming structure 724 is welded to the support structure 734 using the welding washer 742. Advantageously, the use of the welding washer 742 enables different types of trimming structures to be implemented in the portable electronic device 100 that carries three camera modules and the portable electronic device 200 that carries two camera modules. Although Figure 7A-7B For portable electronic device 100, rear wall 730 having first portion 732-A and second portion 732-B can be used interchangeably with portable electronic device 200. Welding washer 742 allows for assembly tolerances by enabling first trimming structure 722 and second trimming structure 724 to be mounted in adjacent locations. Welding washer 742 allows for tight clearance between first trimming structure 722 and second trimming structure 724. Welding washer 742 will be positioned relative to variations in the X and Y directions for different trimming structures, while welding washer 742 floats in the Z direction. In addition, welding washer 742 prevents second trimming structure 724 from impacting support structure 734, particularly where portable electronic device 100 includes multiple trimming structures. Without welding washer 742, it would be necessary to increase the clearance between support structure 734 and second trimming structure 724.

[0086] Figure 8A-8D Various perspective views of operating components of a portable electronic device 800 are shown according to some embodiments. Although described with reference to portable electronic device 100, it should also be noted that the support structures and operating components described herein may be applicable to the embodiment shown in portable electronic device 200. Fig. 8AA perspective view of a portable electronic device 800 is shown that includes a housing having sidewalls 802 that define a cavity. A support plate 850 is disposed within the cavity and secured to a metal strip of the sidewalls 802. The support plate 850 carries a support structure 834 mounted on top of a base 852 of the support plate 850.

[0087] According to some embodiments, support structure 834 includes base plate 836, and openings 808-A, 808-B, and 808-C are formed in base plate 836, and these openings are sized and aligned relative to the first camera module, the second camera module, and the third camera module (e.g., 162-A, 162-B, 162-C). Each of openings 808-A, 808-B, and 808-C is surrounded by a welding washer 842.

[0088] Specifically, the support structure 834 includes a grounding / bias spring 870 that is capable of engaging the camera module to a known position against the wall 844 of the support structure 834. In addition, the grounding / bias spring 870 also grounds the camera module. In some examples, the grounding / bias spring 870 is used as a known reference to bias the camera module into precise alignment with the support plate 850 and the opening in the rear wall (e.g., the rear wall 730). Advantageously, the grounding / bias spring 870 ensures that the aperture of the camera module is centered and aligned. In practice, the camera module can be electronically calibrated using software before being installed in the support structure 834. Therefore, the alignment of the aperture of the camera module is critical. In practice, a misaligned aperture can cause photo vignetting.

[0089] The support structure 834 also includes an opening 860 disposed in the bottom plate 836 that enables a microphone module (e.g., microphone module 560) to align with the openings in the support plate 850 and the rear wall (e.g., rear wall 730). The support structure 834 includes a tab 838 for biasing the microphone module against the wall of the support structure 834.

[0090] Figure 8BA perspective view of a support structure 834 according to some embodiments is shown. The support structure 834 includes openings 808-A, 808-B, and 808-C for camera modules (e.g., a first camera module 510-A, a second camera module 510-B, and a third camera module 510-C). The support structure 834 includes a grounding / biasing spring 870 that engages the camera module to a known position against the wall 844. Each of the openings 808-A, 808-B, and 808-C is surrounded by a welding gasket 842. In practice, the wall 844 of the support structure 834 has a height that allows clearance for the welding gasket 842. The welding gasket 842 can fit within the height of the wall 844. In practice, it is undesirable to extend the welding gasket 842 beyond the height of the wall 844.

[0091] Figure 8C A top perspective view of a camera module assembly 810 according to some embodiments is shown.

Each of the first camera module 810-A, the second camera module 810-B, and the third camera module 810-C includes a corresponding turntable such that when the first camera module 810-A, the second camera module 810-B, and the third camera module 810-C are carried by the support structure 834, the turntable protrudes relative to the distal end of the support structure 834. The first camera module 810-A, the second camera module 810-B, and the third camera module 810-C are carried within a base 820. The base 820 is mounted to a bottom plate 836 of the support structure 834. A grounding / biasing spring 870 biases the base 820 and the camera module assembly 810 to a predetermined position.

[0092] Fig.8D A bottom perspective view of a camera module assembly 810 according to some embodiments is shown. Each of the first camera module 810-A, the second camera module 810-B, and the third camera module 810-C includes a flexible cable to transmit electrical signals to / from a logic board of the portable electronic device 800. The first camera module 810-A is electrically coupled to a first flexible cable 818-A, the second camera module 810-B is electrically coupled to a second flexible cable 818-B, and the third camera module 810-C is electrically coupled to a third flexible cable (not shown).

[0093] Figure 9A-9B Various perspective views of operating components of a portable electronic device according to some embodiments are shown.

[0095] Fig.10 A top view of operating components of a portable electronic device according to some embodiments is shown. Specifically, Fig.10 A support plate 1000 is shown which may correspond to the support plate 450, as shown in FIG. Figure 4 Described. Support plate 1000 includes multiple openings for wireless antennas and camera modules. Specifically, support plate 1000 includes opening 1008-A, which can allow a first camera module (e.g., first camera module 510-A) to pass therethrough. Support plate 1000 includes opening 1008-B, which can allow a second camera module (e.g., second camera module 510-B) to pass therethrough. Support plate 1000 includes opening 1008-C, which can allow a third camera module (e.g., third camera module 510-C) to pass therethrough.

Support plate 1000 includes microphone opening 1018 to allow a microphone module (e.g., microphone module 560) to pass therethrough. The support plate 1000 also includes openings 1020-A, 1020-B, and 1020-C to allow the wireless antenna module to pass therethrough. In some examples, the wireless antenna module is an ultra-wideband antenna. Advantageously, the portable electronic device 100 or the portable electronic device 200 can use the ultra-wideband antenna to communicate with other devices having ultra-wideband antennas to perform functions. The ultra-wideband antenna can perform short-range high-bandwidth communications using a small amount of energy.

[0096] It is noteworthy that the support plate 1000 may be formed of a metal material (eg, stainless steel). Therefore, an opening is cut out from the support plate 1000 to prevent electromagnetic interference.

[0097] Fig.11 A method 1100 for forming a portable electronic device according to some embodiments is shown. Method 1100 begins at step 1102, where a rear wall (e.g., rear wall 530) having an elevated portion (boss portion) is formed. In some embodiments, rear wall 530 includes a first portion 532-A and a second portion 532-B elevated relative to first portion 532-A. In some examples, the elevated portion is formed by a machining process involving machining a portion of the glass of rear wall 530. In some examples, an opening is formed in the elevated portion that can accommodate a turntable of a camera module (e.g., first camera module 510-A).

[0098] At step 1104, the rear wall 530 is coupled to a metal strip (eg, the metal strip 504 of the side wall 502). Thus, the rear wall 530 and the side wall 502 define a cavity 506 in which an operating component can be disposed.

[0099] At step 1106, at least one trim structure (e.g., first trim structure 522 or second trim structure 524) is secured to rear wall 530. In some examples, at least one trim structure is mounted against a surface of rear wall 530. At least one trim structure covers a portion of the raised portion of rear wall 530.

[0100] At step 1108, a camera module (e.g., first camera module 510-A) is secured to support structure 534. At step 1110, support structure 534 carrying the camera module is coupled to at least one trim structure, and rear wall 530. The camera module is aligned with an opening in rear wall 530.

[0101] At step 1112 , a weld washer (eg, weld washer 742 ) is welded to at least one trim structure, and support structure 534 .
