Description

Technical Field

[0001] This application relates to the field of wearable devices, and more particularly to a decorative component and a wearable device. Background Technology

[0002] In the high-end consumer electronics and luxury goods sectors, precious metals such as gold can be used as decorative elements on products. For example, gold can be applied to watch cases using methods such as adhesive bonding or physical vapor deposition. However, these metal decorative elements are prone to detachment over long-term use or due to external environmental factors, resulting in poor reliability. Utility Model Content

[0003] This application provides a decorative component and wearable device, which solves the problem that metal decorative parts are prone to falling off during long-term use or under the influence of the external environment in the product shell of the prior art.

[0004] The embodiments of this application adopt the following technical solutions:

[0005] In a first aspect, embodiments of this application provide a decorative component, including a base and a metal decorative element. The base has a mounting position for mounting the metal decorative element, the mounting position having a front and a back facing away from each other, and an outer peripheral surface located between the front and the back, the front having a groove. The metal decorative element includes a covering portion, a fastening portion, and a limiting portion, the fastening portion being connected to a first end of the covering portion, and the limiting portion being connected to a second end of the covering portion. The fastening portion is fastened to the groove, the covering portion at least covers the mounting position, and the limiting portion is located on the back. The inner surface of the metal decorative element and the mounting position are bonded together by an adhesive.

[0006] The decorative component provided in this application embodiment has a metal decorative element installed at the mounting position of the substrate. The covering portion of the metal decorative element covers the mounting position, the fastening portion is fastened to a groove on the front of the mounting position, and the limiting portion is located on the back of the mounting position, thus physically limiting the metal decorative element. The inner surface of the metal decorative element and the mounting position are bonded together with an adhesive, achieving complete fixation of the metal decorative element to the substrate. During long-term use, or under the influence of external environmental factors such as temperature, humidity, or corrosive liquids, the metal decorative element, due to its physical limitation, is not easily detached from the substrate, resulting in good connection reliability between the metal decorative element and the substrate.

[0007] In one alternative implementation, the metal decorative element can be made of precious metals such as gold, silver, or platinum. The substrate and the metal decorative element are made of different materials; the metal decorative element is placed on the substrate, providing both aesthetic appeal and aesthetic value.

[0008] In one alternative implementation, the substrate material is ceramic, stainless steel, titanium alloy, amorphous zirconium alloy, or plastic. These substrate materials allow for good bonding with the metal decorative element, achieving a reliable connection between the metal decorative element and the substrate.

[0009] In one alternative implementation, the mounting location is a receiving groove, in which the metal decorative piece is embedded. This embedding of the metal decorative piece onto the substrate achieves a combination of the decorative piece and the substrate, resulting in a better aesthetic appearance for the substrate with the metal decorative piece installed.

[0010] In one alternative implementation, the outer surface of the covering part is adapted to the outer surface of the substrate, that is, the two surfaces are flush or close to each other. This gives the substrate with the metal decorative parts a better appearance.

[0011] In one alternative implementation, the base is a bezel or a mid-frame. Metal decorative elements can be placed on the bezel or mid-frame to create a decorative effect.

[0012] In one alternative implementation, six mounting positions are spaced along the bezel's extension direction, with a metal decorative element at each mounting position. The six metal decorative elements are arranged at intervals along the bezel. The metal decorative elements can extend a certain distance circumferentially along the bezel and cover part of the bezel's outer edge, making the metal decorative element an integral structure with the bezel.

[0013] In one alternative implementation, the mid-frame has two lugs, each lug having two mounting positions spaced apart, and each mounting position having a metal decorative element. The metal decorative element extends in a generally curved manner and wraps around the lug.

[0014] In one alternative implementation, the covering portion includes a first wall, a second wall, and a third wall connected in sequence. The first wall is inclined relative to the second wall, and the third wall is inclined relative to the second wall. The first wall is positioned opposite the front side, while the second and third walls are both positioned opposite the outer peripheral surface of the mounting position, with the third wall located near the back side. A fastening portion is connected to the inner surface of the first wall, and a limiting portion is connected to the edge of the third wall. By covering the outer edge of the substrate with the bent covering portion, the substrate on which the metal decorative element is mounted has a better aesthetic effect.

[0015] In one alternative implementation, the substrate is a bezel, with the first wall of the covering portion positioned near the front of the bezel, and the second and third walls positioned near the outer periphery of the bezel.

[0016] In one alternative implementation, the covering portion and the limiting portion are independent parts when not connected. After the covering portion is fixed to the mounting position using an adhesive, the limiting portion is bonded to the back of the mounting position, and the second end of the covering portion is welded to the limiting portion. By providing the limiting portion on the back of the mounting position, the metal decorative part is limited to the base. This method is suitable for scenarios where the limiting portion is obstructed by other components, and welding is easily achieved.

[0017] In one alternative implementation, the covering part and the limiting part are an integral structure, with the limiting part bent relative to the covering part. After the covering part is fixed to the mounting position using an adhesive, the limiting part is bent relative to the covering part, so that the limiting part is located on the back of the mounting position, thus limiting the metal decorative part to the base. This method is suitable for scenarios where the limiting part is not obstructed by other components, and the connection between the limiting part and the covering part has a good appearance and minimal impact on the overall look.

[0018] In one alternative implementation, the fastener and the slot are bonded together with adhesive, and the covering part and the outer peripheral surface of the mounting position are bonded together with adhesive. The adhesive secures the fastener to the slot and the covering part to the outer peripheral surface of the mounting position.

[0019] In one alternative implementation, a support portion is provided on the front side of the mounting position, and the covering portion is located on the support portion. The support portion can be a thin sheet or a boss on the front side. This allows the flowing adhesive to better fill the gap between the covering portion and the mounting position, and the support portion can limit the thickness of the adhesive, preventing the adhesive from completely flowing out of the gap between the covering portion and the mounting position.

[0020] In one alternative implementation, the dimension of a single metal decorative element along the outer edge of the substrate is smaller than the perimeter of the substrate's outer edge. The outer edge of the substrate can be approximately annular, such as a circle or a rounded rectangle. One or more small metal decorative elements are placed on the substrate, displaying a predetermined pattern, achieving a desired appearance effect as needed. A variety of appearance effects can be achieved. The size of the metal decorative elements can be made small, and their proportion relative to the substrate can be minimized, resulting in a lighter overall weight.

[0021] In one alternative implementation, the slot extends along a first direction, the fastener extends along the first direction, and the fastener is assembled into the slot along the first direction to limit the metal decorative piece to the substrate in the direction perpendicular to the first direction. Fastening the fastener into the slot of the substrate along the first direction limits the metal decorative piece to the substrate, reducing the likelihood of the metal decorative piece detaching from the substrate in the direction perpendicular to the first direction.

[0022] In one alternative implementation, the fastener, covering part, and limiting part can be arranged in a roughly C-shape on the cross section passing through them. The C-shaped structure is clamped at the edge of the base, fastened to the groove by the fastener, and the limiting part is located on the back of the mounting position, thereby limiting the metal decorative part to the base.

[0023] In one alternative implementation, the buckle and the cover can be an integral structure. Alternatively, the buckle and the cover can be separate parts.

[0024] In one alternative implementation, the cross-sectional shapes of the buckle and the slot can be compatible non-circular, such as both being rectangular. When the buckle is fastened to the slot, the metal decorative piece is confined to the base without wobbling, thus confining the metal decorative piece to the base in the vertical direction of the first direction.

[0025] In one alternative implementation, the covering portion extends along a second direction; multiple fasteners are arranged along the second direction. The covering portion is configured as a strip structure extending along the second direction, thus reliably securing the metal decorative piece to the substrate.

[0026] In one alternative implementation, the slots of the fasteners and the base can be configured in a one-to-one correspondence. Alternatively, two fasteners can be configured to correspond to one slot, meaning the two fasteners share one slot.

[0027] In one alternative implementation, the first end of the covering portion is provided with two buckles spaced apart along the second direction. The buckles are smaller in size along the second direction, so that the metal decorative parts are reliably fixed on the base, thereby reducing the cost of using precious metals in the buckles.

[0028] In one alternative implementation, the first end of the covering portion is provided with a plurality of fasteners spaced apart along the second direction. The plurality of fasteners are symmetrically distributed with respect to the symmetrical face of the covering portion, or they can be asymmetrically distributed.

[0029] In one alternative implementation, there may be a single fastener. The fastener may be a strip-shaped structure extending along the second direction. Alternatively, the fastener may be a protrusion, with a smaller dimension along the second direction.

[0030] In one alternative implementation, the slot can be a recess on the front side, extending along a first direction. The substrate has good mechanical strength near the slot. The fastener engages with the recess, confining the metal decorative piece to the substrate in a direction perpendicular to the first direction.

[0031] In one alternative implementation, the slot can be a through slot, extending through both the front and back sides. Through slots are easy to manufacture. The fastener engages with the through slot, confining the metal decorative piece to the base in a direction perpendicular to the first direction.

[0032] In one alternative implementation, the number of limiting portions can be one or more. For example, there can be one limiting portion, which can extend along the second direction and can be located at the middle of the second end of the covering portion. Alternatively, there can be two limiting portions, which are located at opposite ends of the second end of the covering portion.

[0033] In one alternative implementation, in the second direction, the centers of the limiting part and the fastening part can be staggered or arranged correspondingly.

[0034] In one alternative implementation, the first end of the covering portion is provided with two buckles spaced apart along the second direction, and the middle of the second end of the covering portion is provided with a limiting portion, wherein in the second direction, a limiting portion is located between the two buckles.

[0035] In one alternative implementation, the first end of the covering portion is provided with two buckles spaced apart along the second direction, and the two opposite sides of the second end of the covering portion are respectively provided with a limiting portion, with the two buckles and the two limiting portions arranged in a one-to-one correspondence.

[0036] In one alternative implementation, the metal decorative piece has multiple fasteners and mounting slots, with the slots extending along a first direction and the fasteners extending along the first direction. On a plane perpendicular to the first direction, two fasteners are arranged in a V-shape, and two corresponding slots are also arranged in a V-shape. The fasteners are fastened to the slots along the first direction in a one-to-one correspondence, thus limiting the metal decorative piece to the base along the vertical direction of the first direction.

[0037] In one alternative implementation, the buckle and the covering part can be an integral structure. One end of the buckle is connected to the first end of the covering part, and the side of the buckle is connected to the inner surface of the covering part, so that the buckle and the covering part are reliably connected. The buckle and the covering part can also be independent parts.

[0038] In one alternative implementation, the covering portion extends along a second direction; a plurality of fasteners are arranged along the second direction. The covering portion is configured as a strip structure extending along the second direction.

[0039] In one alternative implementation, the slot can be a through slot extending through both the front and back sides. Alternatively, the slot can be a recess on the front side, extending along a first direction. Both the recess and the through slot can engage with the fastener to secure the metal decorative piece to the base in a direction perpendicular to the first direction.

[0040] In one alternative implementation, the number of limiting portions can be one or more. For example, there can be one limiting portion, which can extend along the second direction and can be located at the middle of the second end of the covering portion. Alternatively, there can be two limiting portions, which are located at opposite ends of the second end of the covering portion.

[0041] In one alternative implementation, the fastener includes a first portion and a second portion. The first portion extends along a first direction and connects between a first end of the covering portion and the second portion. The width of the first portion is smaller than the width of the second portion. The slot has an undercut, and the fastener is assembled into the slot along the first direction. The second portion is fastened to the undercut to limit the metal decorative piece to the base.

[0042] In one alternative implementation, the fastener, covering part, and limiting part can be arranged in a roughly C-shape on the cross section passing through them. The C-shaped structure is clamped at the edge of the base, fastened to the groove by the fastener, and the limiting part is located on the back of the mounting position, thereby limiting the metal decorative part to the base.

[0043] In one alternative implementation, the buckle and the covering can be an integral structure. Alternatively, the buckle and the covering can be separate parts, which are fixed together by welding.

[0044] In one alternative implementation, the projection of the inverted buckle on the vertical plane of the first direction is U-shaped. Inserting the buckle, which has a first part and a second part, into the slot, such that the second part is fastened to the U-shaped inverted buckle, confines the metal decorative piece to the base along the first direction and the direction perpendicular to the first direction, preventing the metal decorative piece from easily detaching from the base.

[0045] In one alternative implementation, the opening of the U-shaped buckle can be oriented towards the outer edge of the substrate. The second part of the buckle is inserted through the opening of the buckle, so that the second part and the buckle are fastened together. The adhesive is applied by dispensing, and the adhesive can be filled between the surfaces of the buckle and the groove, and also between the inner surface of the covering part and the outer peripheral surface of the mounting position, so that the metal decorative part is reliably fixed in the mounting position.

[0046] In one alternative implementation, the covering portion and the limiting portion are an integral structure, with the limiting portion bent to cover the bottom edge of the substrate. This reliably fixes the metal decorative piece to the substrate. The limiting portion can be bent once relative to the covering portion, and the limiting portion itself can also be bent once, so that the limiting portion stably covers the bottom edge of the substrate.

[0047] In one alternative implementation, the bending position of the limiting part has a bending groove. This facilitates the bending of the limiting part to cover the second end of the substrate.

[0048] In one alternative implementation, the covering part and the limiting part are independent components when not connected. After the covering part is fixed in the mounting position using an adhesive, the limiting part is bonded to the back surface. The limiting part can be pre-fixed using spot adhesive or back adhesive. The second end of the covering part is welded to the limiting part. The welding and fixing of the covering part and the limiting part are achieved by laser spot welding or melting gold wire. This method is suitable for scenarios where the limiting part is obstructed by other components, and the welding process is easy to implement.

[0049] In one alternative implementation, the second part of the buckle can be configured with a different shape, such that the buckle is assembled into the slot along the first direction Z, the second part is fastened to the undercut, and the metal decorative piece is positioned on the base. For example, in the vertical plane of the first direction, the second part is circular. Alternatively, in the vertical plane of the first direction, the second part can be a rectangle extending along a third direction.

[0050] In one alternative implementation, there is a single fastener. This single fastener is secured in a groove in the base, allowing the metal decorative element to be held in place on the base.

[0051] In one alternative implementation, the covering portion extends along a second direction; multiple fasteners are arranged along the second direction. The covering portion is configured as a strip structure extending along the second direction. By providing two or more fasteners, the metal decorative piece can be reliably positioned on the base. The slots in the fasteners and the base can be configured in a one-to-one correspondence.

[0052] In one alternative implementation, the first end of the covering portion is provided with two buckles spaced apart along the second direction. The buckles are smaller in size along the second direction, so that the metal decorative parts are reliably fixed on the base, thereby reducing the cost of using precious metals in the buckles.

[0053] In one alternative implementation, the slot can be a recess on the front side, extending along a first direction. Alternatively, the slot can be a through slot, extending through both the front and back sides. The metal decorative piece is positioned on the base in a direction perpendicular to the first direction.

[0054] In one alternative implementation, the number of limiting portions can be one or more. For example, there can be one limiting portion, which can extend along the second direction and can be located at the middle of the second end of the covering portion. Alternatively, there can be two limiting portions, which are located at opposite ends of the second end of the covering portion.

[0055] Secondly, embodiments of this application provide a wearable device including the aforementioned decorative component. The decorative component includes a base and a metal decorative element. The metal decorative element is disposed on the base, which can be a bezel and / or a mid-frame. That is, the metal decorative element can be disposed on the bezel, or on the mid-frame, or both the bezel and the mid-frame can have metal decorative elements disposed on them. The shape, quantity, and position of the metal decorative element can be set as needed, allowing the wearable device to achieve a variety of aesthetic effects.

[0056] In one alternative implementation, the wearable device is a smartwatch / electronic watch, and circuit board assemblies, batteries, sensors, and other components can be arranged within the mid-frame. A display screen can be mounted on one side of the mid-frame, and a back cover can be mounted on the other side. The bezel is located on the side of the display screen.

[0057] In one alternative implementation, the wearable device is a mechanical watch, with the movement and other components housed within the frame. The dial and crystal can be mounted on one side of the frame, while the case back can be mounted on the other side. The bezel is positioned on one side of the dial.

[0058] In one alternative implementation, the metal decorative element includes a first decorative element and a second decorative element, with a plurality of first decorative elements disposed on the bezel and a plurality of second decorative elements disposed on the middle frame.

On the contrary, the purpose of describing the application in conjunction with embodiments is to cover other options or modifications that may arise based on the claims of this application. To provide a thorough understanding of this application, many specific details will be included in the following description. This application may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this application, some specific details will be omitted in the description. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0104] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component.

The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0109] See Figure 1A In related technologies, the metal decorative part 12 can be bonded and fixed to the product casing. For example, a mounting position 11a is machined on the watch case 11, and the metal decorative part 12 is bonded to the mounting position 11a of the watch case 11 using adhesive 13. This method is greatly affected by external environmental factors such as temperature, humidity, and corrosive liquids, and the adhesive 13 has a high probability of failure, resulting in a significant reliability risk of the metal decorative part 12 falling off.

[0110] In related technologies, metal decorative elements can be deposited onto the product casing. Physical vapor deposition (PVD) is used to plate metal onto the casing surface to form a metal coating, i.e., the metal decorative element. This method is suitable for watch bezels or large surfaces of the watch case. The metal coating thickness is relatively thin, such as 2 to 20 micrometers. In complex or high-intensity usage scenarios, the metal coating is prone to wear and peeling, resulting in the exposure of the underlying metal coating or discoloration of the transition layer, thus deteriorating the appearance.

[0111] See Figure 1B In related technologies, the metal ring 22 can be embedded in the product case, such as embedding the metal ring 22 in the bezel 21 of a watch. The metal can be wrapped and fixed to the entire surface of the product case, for example, a whole metal sheet can be nested into the surface of the case and pressed into shape. This method uses metal decorative parts arranged around the entire ring or on the front of the case, resulting in poor aesthetic diversity and fewer achievable visual effects; moreover, the large proportion of metal decorative parts makes the overall weight of the watch relatively heavy.

[0112] See Figure 2 and Figure 3This application provides a wearable device 1000, which can be a watch, bracelet, etc. The watch can be a smartwatch, electronic watch, or mechanical watch. The wearable device 1000 can include a housing. When the wearable device is a watch or bracelet, the housing can also be called a watch case. The watch case can include a bottom case 500 and a middle frame 300. Optionally, the watch case can also include a bezel 200.

[0113] In the case where the wearable device 1000 is a smartwatch / electronic watch, circuit board assemblies, batteries, sensors, and other components can be arranged inside the casing. A display screen 400 can be installed on one side of the mid-frame 300, and a back cover 500 can be installed on the other side of the mid-frame 300. A bezel 200 is located on one side of the display screen 400.

[0114] In the case of a mechanical watch (wearable device 1000), the movement and other components can be housed inside the case. The dial and crystal can be mounted on one side of the middle frame 300, and the back case 500 can be mounted on the other side. The bezel 200 is located on one side of the dial.

[0115] Wearable device 1000 includes a decorative component 100. The decorative component 100 includes a base 110 and a metal decorative element 120. The metal decorative element 120 is disposed on the base 110, which can be a bezel 200 and / or a mid-frame 300. That is, the metal decorative element 120 can be disposed on the bezel 200, or on the mid-frame 300, or both the bezel 200 and the mid-frame 300 can have metal decorative elements 120 disposed on both. The shape, quantity, and position of the metal decorative element 120 can be configured as needed, allowing the wearable device 1000 to achieve various aesthetic effects. It should be noted that this application embodiment uses a bezel and mid-frame as examples for illustration, but this application embodiment is not limited to these, and the base 110 can also be other components.

[0116] For example, the metal decorative element 120 includes a first decorative element 120a and a second decorative element 120b. A plurality of first decorative elements 120a may be provided on the bezel 200, and a plurality of second decorative elements 120b may be provided on the middle frame 300.

[0117] It should be noted that the above is merely an example. The wearable device 1000 may include only the first decorative element 120a, or only the second decorative element 120b. The first decorative element 120a may be located in a position other than the bezel 200, and the second decorative element 120b may also be located in a position other than the middle frame 300. This application embodiment does not limit the number of the first decorative element 120a and the second decorative element 120b; there may be one or more (e.g., 2, 3, 4, 5, 6, 8, etc.).

[0118] To facilitate the description of the orientation and orientation of the components of the wearable device 1000, the plane containing the bezel 200 is defined as the XY plane, with the X and Y directions lying within it. The thickness direction of the bezel 200 is defined as the Z direction, which is perpendicular to the XY plane. The terms "first direction," "second direction," and "third direction" are also mentioned below. The first direction is the Z direction, the second direction is the A direction, and the third direction is the B direction, both lying within the XY plane. The direction perpendicular to the first direction can be any direction within the XY plane, such as the X or Y direction.

[0119] See Figures 4 to 7 This application provides a decorative component 100, including a base 110 and a metal decorative element 120. The base 110 has a mounting position 111 for mounting the metal decorative element 120, combined with... Figure 8 The mounting position 111 has a front side 111a and a back side 111b facing away from each other, and an outer peripheral surface 111c located between the front side 111a and the back side 111b. The front side 111a has a groove 1111. In other words, the front side 111a and the back side 111b are arranged opposite to each other, and the outer peripheral surface 111b is connected to both the front side 111a and the back side 111b. See reference. Figure 5A , Figure 5B The metal decorative part 120 includes a covering portion 121, a fastening portion 122, and a limiting portion 123. The fastening portion 122 is connected to a first end 121a of the covering portion 121, and the limiting portion 123 is connected to a second end 121b of the covering portion 121. (See reference...) Figure 8 The fastener 122 is fastened to the slot 1111, and the covering part 121 at least covers the mounting position 111, in combination. Figure 7 , Figure 9 The limiting part 123 is provided on the back side 111b. The inner surface of the metal decorative part 120 and the mounting position 111 can be bonded together by adhesive 130.

[0120] The first end 121a and the second end 121b of the covering portion 121 can be the two opposite ends of the covering portion 121.

[0121] The outer and inner surfaces of the metal decorative element 120 are opposite sides. The outer surface of the metal decorative element 120 is the surface that is visible after the metal decorative element 120 is installed on the base 110, while the inner surface is not visible.

[0122] The adhesive 130 can be applied by dispensing, backing, or other methods. Before assembly, the adhesive 130 can be applied to the inner surface of the metal decorative part 120 or the mounting position 111, and the metal decorative part 120 can be fixed to the mounting position 111 by means of the adhesive 130.

[0123] The decorative component 100 provided in this application embodiment has a metal decorative element 120 disposed at the mounting position 111 of the base 110. The covering portion 121 of the metal decorative element 120 covers the mounting position 111, the fastening portion 122 is fastened to the groove 1111 on the front side 111a of the mounting position 111, and the limiting portion 123 is disposed on the back side 111b of the mounting position 111, thus physically limiting the metal decorative element 120. The inner surface of the metal decorative element 120 and the mounting position 111 are bonded together by an adhesive 130, achieving complete fixation of the metal decorative element 120 to the base 110. During long-term use, or under the influence of external environments such as temperature, humidity, or corrosive liquids, the metal decorative element 120, being physically limited, is not easily detached from the base 110, and the connection reliability between the metal decorative element 120 and the base 110 is good.

[0124] In some embodiments, see Figures 2 to 4 The metal decorative element 120 can be made of precious metals such as gold, silver, or platinum. The base 110 and the metal decorative element 120 are made of different materials. The metal decorative element 120 is placed on the base 110, providing both aesthetic appeal and aesthetic value. It should be noted that the materials used for the metal decorative element described above are merely examples, and other materials may also be used.

[0125] In some embodiments, see Figures 2 to 4 The substrate 110 is made of ceramic, stainless steel, titanium alloy, amorphous zirconium alloy, or plastic. These materials allow the substrate 110 to bond well with the metal decorative element 120, achieving a reliable connection between the metal decorative element 120 and the substrate 110.

[0126] In some embodiments, see Figure 6 , Figure 8 The mounting position 111 is a receiving groove, and the metal decorative part 120 is embedded in the receiving groove. The metal decorative part 120 is embedded in the base 110, realizing the combination of the metal decorative part 120 and the base 110. This gives the base 110 with the metal decorative part 120 a better appearance.

[0127] The outer surface 121c of the covering part 121 and the outer surface 110a of the base 110 are adapted to each other, that is, the two surfaces are flush or close to each other, for example, the distance between the two surfaces is within 3 mm. This gives the base 110 on which the metal decorative part 120 is installed a better appearance.

[0128] In some embodiments, see Figures 2 to 4 The base 110 is either the bezel 200 or the middle frame 300. Metal decorative elements 120 can be placed on the bezel 200 or the middle frame 300 to create a decorative effect. The shape, position, and number of the metal decorative elements 120 are not limited.

[0129] For example, see Figure 4 Along the extension direction of the bezel 200, six mounting positions 111 are spaced apart on the bezel 200, and a metal decorative element 120 is provided at each mounting position 111. The bezel 200 has six metal decorative elements 120 arranged at intervals. The metal decorative elements 120 can extend a certain distance along the circumference of the bezel 200 and cover part of the outer peripheral edge of the bezel 200, so that the metal decorative elements 120 and the bezel 200 are integrated into one structure.

[0130] For example, see Figure 2 , Figure 3 The middle frame 300 has two lugs 301, each lug 301 having two mounting positions 111 spaced apart, and each mounting position 111 having a metal decorative piece 120. The metal decorative piece 120 extends in a generally curved manner and wraps around the lug 301.

[0131] In some embodiments, see Figure 5A , Figure 8 The covering portion 121 of the metal decorative part 120 can be bent. The covering portion 121 can cover the front surface 111a and the outer peripheral surface 111c. For example, the covering portion 121 includes a first wall 1211, a second wall 1212, and a third wall 1213 connected in sequence. The first wall 1211 is inclined relative to the second wall 1212, and the third wall 1213 is inclined relative to the second wall 1212. The first wall 1211 is opposite to the front surface 111a, the second wall 1212 and the third wall 1213 are both opposite to the outer peripheral surface 111c of the mounting position 111, and the third wall 1213 is located close to the back surface 111b. The fastening portion 122 is connected to the inner surface of the first wall 1211, and the limiting portion 123 is connected to the edge of the third wall 1213. By covering the outer edge of the base 110 with the bent covering portion 121, the base 110 on which the metal decorative part 120 is mounted has a better appearance.

[0132] For example, see Figure 8 The base 110 is the bezel 200. The first wall 1211 of the covering portion 121 is disposed near the front surface of the bezel 200, and the second wall 1212 and the third wall 1213 are disposed near the outer peripheral surface of the bezel 200. During the process of assembling the metal decorative piece 120 from top to bottom into the groove 1111 of the base 110 along the first direction Z, the third wall 1213 of the covering portion 121 abuts against the surface of the mounting position 111 and undergoes slight bending deformation until the buckle 122 is fully inserted into the groove 1111 of the base 110. The third wall 1213 then deforms and returns to its original position so that the second wall 1212 and the third wall 1213 of the covering portion 121 cover the outer peripheral surface of the bezel 200.

[0133] There are several possible implementation methods for connecting the covering part 121 and the limiting part 123. Two implementation methods are given below as examples.

[0134] The first connection method between the covering part 121 and the limiting part 123: see [link / reference] Figure 5A and Figure 5B When the covering part 121 and the limiting part 123 are not connected, they are independent parts. Figure 9 After the covering part 121 is fixed to the mounting position 111 using adhesive 130, the limiting part 123 is bonded to the back surface 111b of the mounting position 111. The limiting part 123 can be pre-fixed using spot adhesive or back adhesive. The second end 121b of the covering part 121 and the limiting part 123 are welded together. The welding and fixing of the covering part 121 and the limiting part 123 are achieved by laser spot welding and melting gold wire. By setting the limiting part 123 on the back surface 111b of the mounting position 111, the metal decorative part 120 is limited to the base 110. The welding position of the covering part 121 and the limiting part 123 can be polished to smooth the weld bar and obtain a smooth surface. This method is suitable for scenarios where the limiting part 123 is obstructed by other components, and the welding process is easy to implement.

[0135] For example, see Figure 3 The base 110 is the bezel 200, the metal decorative part 120 is mounted on the bezel 200, and the limiting part 123 is disposed near the back of the bezel 200. In the wearable device, the limiting part 123 and the middle frame 300 are disposed facing each other, and the limiting part 123 is covered by the middle frame 300. The covering part 121 and the limiting part 123 can be independent parts. After the covering part 121 and the limiting part 123 are respectively assembled in the mounting position 111, the second end 121b of the covering part 121 and the limiting part 123 are welded together.

[0136] The second connection method between the covering part 121 and the limiting part 123: The covering part 121 and the limiting part 123 are an integral structure, with the limiting part 123 bent relative to the covering part 121. After the covering part 121 is fixed to the mounting position 111 using the adhesive 130, the limiting part 123 can be bent relative to the covering part 121 using processes such as riveting, so that the limiting part 123 is located on the back side 111b of the mounting position 111, thus limiting the metal decorative part 120 to the base 110. This method is suitable for scenarios where the limiting part 123 is not obstructed by other components, and the connection position between the limiting part 123 and the covering part 121 has a better appearance and less impact on the overall appearance.

[0137] For example, see Figure 3 The base 110 is the middle frame 300, the metal decorative part 120 is installed on the middle frame 300, and the limiting part 123 is located near the back of the middle frame 300. In the wearable device, the limiting part 123 is not obstructed by other components. The covering part 121 and the limiting part 123 can be an integral structure. After the covering part 121 is assembled into the mounting position 111, the limiting part 123 is bent so that it is located on the back 111b of the mounting position 111.

[0138] In some embodiments, see Figure 8 The buckle 122 and the groove 1111 are bonded together by adhesive 130, and the covering part 121 and the outer peripheral surface 111c of the mounting position 111 are bonded together by adhesive 130. The adhesive 130 secures the buckle 122 to the groove 1111 and the covering part 121 to the outer peripheral surface 111c of the mounting position 111. The adhesive 130 can be applied by dispensing, such as hot melt adhesive or epoxy adhesive. Dispensing adhesive onto the inner surface of the metal decorative part 120 or the surface of the mounting position 111 allows the uncured adhesive to flow under pressure and fill the gap between the covering part 121 and the mounting position 111 during the attachment of the metal decorative part 120 to the mounting position 111. After the adhesive 130 cures, the metal decorative part 120 is reliably fixed to the mounting position 111.

[0139] In some embodiments, see Figure 6 A support portion 1113 is provided on the front side 111a of the mounting position 111, and a covering portion 121 is located on the support portion 1113. The support portion 1113 can be a thin sheet or a boss provided on the front side 111a. Adhesive is applied to the inner surface of the metal decorative part 120 or the surface of the mounting position 111. During the process of attaching the metal decorative part 120 to the mounting position 111, the flowing adhesive can better fill the gap between the covering portion 121 and the mounting position 111. The support portion 1113 can limit the thickness of the adhesive and prevent the adhesive from flowing out completely from the gap between the covering portion 121 and the mounting position 111.

[0140] In some embodiments, see Figure 2 The dimension L1 of a single metal decorative piece 120 in the direction of the outer edge of the base 110 is smaller than the perimeter of the outer edge of the base 110. The outer edge of the base 110 can be roughly annular, such as a circle or a rounded rectangle.

[0141] See Figure 2 , Figure 4 When the metal decorative element 120 extends along the outer edge of the base 110, the dimension L1 of the metal decorative element 120 in the outer edge direction of the base 110 is the length of the covering portion 121 of the metal decorative element 120.

[0142] See Figure 2 , Figure 3 When the metal decorative part 120 bends and extends approximately along the thickness direction of the base 110, the dimension L2 of the metal decorative part 120 in the direction of the outer edge of the base 110 is the width of the covering portion 121 of the metal decorative part 120.

[0143] One or more small metal decorative parts 120 are disposed on the base 110. The metal decorative parts 120 on the base 110 present a predetermined pattern and can achieve a predetermined appearance effect as needed. There are many forms of appearance effect that can be achieved.

[0144] Compared to related technologies where the metal ring is entirely embedded in the product casing, the size of the metal decorative part 120 in this embodiment can be made smaller, and the proportion of the metal decorative part 120 relative to the base 110 is smaller, resulting in a lighter overall weight. When the metal decorative part 120 is applied to the wearable device 1000, the wearable device 1000 has a lighter weight, resulting in a better user experience.

[0145] There are several possible implementation methods when setting the buckle 122 and the slot 1111. Three possible implementation methods are given as examples below.

[0146] The first implementation method of the buckle 122 and the slot 1111 is as follows: Figures 4 to 9 As shown, both the buckle 122 and the slot 1111 extend along the first direction Z.

[0147] The second implementation method of the buckle 122 and the slot 1111 is as follows: Figures 11 to 15 As shown, the two buckle parts 122 are arranged in a figure-eight pattern, and the two slots 1111 corresponding to the two buckle parts 122 are also arranged in a figure-eight pattern.

[0148] The third implementation method of the buckle 122 and the slot 1111, such as Figures 17 to 22 As shown, the buckle 122 includes a first part 1221 and a second part 1222. The width d1 of the first part 1221 is smaller than the width d2 of the second part 1222. The slot 1111 has an undercut 1112.

[0149] The various implementations of the buckle 122 and slot 1111 can be applied to the bezel 200, the middle frame 300, or other product housings.

[0150] The following describes the implementation method of the first type of buckle 122 and slot 1111.

[0151] In some embodiments, see Figure 5A , Figure 5B , Figure 6 , Figure 8 The groove 1111 extends along the first direction Z, and the buckle 122 extends along the first direction Z. The buckle 122 is assembled in the groove 1111 along the first direction so that the metal decorative part 120 is limited to the base 110 in the direction perpendicular to the first direction (such as the X direction or the Y direction). The buckle 122 can be referred to as a rib.

[0152] The fastener 122 is fastened to the groove 1111 of the base 110 along the first direction Z, which can limit the metal decorative part 120 on the base 110 and reduce the possibility of the metal decorative part 120 detaching from the base 110 in the vertical direction of the first direction.

[0153] Combination Figure 9The limiting part 123 is connected to the second end 121b of the covering part 121 and is provided on the back side 111b of the mounting position 111. The limiting part 123 plays a limiting role in the first direction Z, reducing the situation where the metal decorative part 120 separates from the substrate 110 in the first direction Z.

[0154] On the cross section passing through the buckle 122, the covering part 121 and the limiting part 123, the buckle 122, the covering part 121 and the limiting part 123 can be arranged in a roughly C-shape. The C-shaped structure is clamped at the edge of the base 110 and fastened to the groove 1111 by the buckle 122. The limiting part 123 is provided on the back side 111b of the mounting position 111, so that the metal decorative part 120 is limited to the base 110.

[0155] The buckle 122 and the covering part 121 can be an integral structure, for example, machined using a CNC machine tool. Alternatively, the buckle 122 and the covering part 121 can be separate parts, fixed together by welding. Using the above methods, the buckle 122 and the covering part 121 of the metal decorative part 120 are easy to process.

[0156] The cross-sectional shapes of the buckle 122 and the slot 1111 can be non-circular and compatible, such as both being rectangular. When the buckle 122 is fastened to the slot 1111, the metal decorative part 120 is limited to the base 110 without shaking, thus limiting the metal decorative part 120 to the base 110 in the vertical direction (such as the X direction or the Y direction) of the first direction.

[0157] In some embodiments, see Figure 5A , Figure 6 The covering portion 121 extends along the second direction A; there are multiple fasteners 122, which are arranged along the second direction A. The second direction A is a direction within the XY plane, and can be a straight line or an arc. The covering portion 121 is configured as a strip structure extending along the second direction. By providing two or more fasteners 122, the metal decorative piece 120 can be reliably positioned on the base 110.

[0158] The buckle 122 and the slot 1111 of the base 110 can be set one-to-one. Alternatively, two buckles 122 can be set to one slot 1111, that is, two buckles 122 share one slot 1111.

[0159] For example, the first end 121a of the covering portion 121 is provided with two buckle portions 122 that are spaced apart along the second direction A. The buckle portions 122 have a small size along the second direction A, so that the metal decorative piece 120 is reliably fixed on the base 110, thereby reducing the cost of using precious metals in the buckle portions 122.

[0160] For example, the first end 121a of the covering portion 121 is provided with a plurality of fasteners 122 spaced apart along the second direction A. The plurality of fasteners 122 are symmetrically distributed with respect to the symmetrical surface of the covering portion 121, or they may be asymmetrically distributed.

[0161] In some embodiments, there may be a single fastener 122. The fastener 122 may be a strip-shaped structure extending along the second direction A. Alternatively, the fastener 122 may be protruding, and the size of the fastener 122 along the second direction A may be small. A single fastener 122 is fastened to the groove 1111 of the base 110, which can limit the metal decorative piece 120 to the base 110.

[0162] In some embodiments, see Figure 6 , Figure 8 The groove 1111 can be a recess provided on the front side 111a, and the groove extends along the first direction Z. The base 110 has good mechanical strength near the groove 1111. The fastener 122 can be fastened to the groove, limiting the metal decorative piece 120 in the vertical direction (e.g., X direction, Y direction) of the first direction to the base 110.

[0163] In other embodiments, the slot 1111 can be a through slot, extending through the front side 111a and the back side 111b. Through slots are easy to manufacture. The buckle 122 engages with the through slot, limiting the metal decorative piece 120 to the base 110 along a direction perpendicular to the first direction (e.g., X-axis, Y-axis).

[0164] When machining the slot 1111 in the substrate 110, laser processing, CNC machine tool processing, or direct forming of the blank can be used.

[0165] In some embodiments, the number of limiting portions 123 can be one or more. For example, see [reference needed]. Figure 5A The limiting part 123 is one, and the limiting part 123 can extend along the second direction A. The limiting part 123 can be disposed in the middle of the second end 121b of the covering part 121. Alternatively, refer to Figure 10 There are two limiting parts 123, which are provided at opposite ends of the second end 121b of the covering part 121.

[0166] In the second direction A, the center of the limiting part 123 and the fastening part 122 can be staggered or arranged correspondingly.

[0167] For example, see Figure 5A The first end 121a of the covering portion 121 is provided with two buckle portions 122 distributed at intervals along the second direction A, and a limiting portion 123 is provided in the middle of the second end 121b of the covering portion 121. In the second direction A, a limiting portion 123 is located between the two buckle portions 122.

[0168] Or, see Figure 10 Two buckle portions 122 are provided at the first end 121a of the covering portion 121, which are spaced apart along the second direction A. A limiting portion 123 is provided on each of the opposite sides of the second end 121b of the covering portion 121. The two buckle portions 122 and the two limiting portions 123 are arranged in a one-to-one correspondence.

[0169] The second method for implementing the buckle 122 and slot 1111 is described below.

[0170] In some embodiments, see Figures 11 to 15 The metal decorative piece 120 has multiple fasteners 122 and mounting slots 1111. The slots 1111 extend along the first direction Z, and the fasteners 122 also extend along the first direction Z. On the vertical plane (XY plane) of the first direction, two fasteners 122 are arranged in a V-shape, and two corresponding slots 1111 are also arranged in a V-shape. The fasteners 122 are fitted one-to-one into the slots 1111 along the first direction Z, thus limiting the metal decorative piece 120 to the base 110 along the vertical direction of the first direction (e.g., X-axis, Y-axis).

[0171] See Figures 14A to 14C The two fasteners 122 are arranged in a V-shape, and the distance between the two fasteners 122 can gradually decrease or gradually increase in the direction from the inner edge 120c to the outer edge 120d of the metal decorative piece 120. The two slots 1111 of the base 110 are configured to fit the two fasteners 122, so that the two fasteners 122 can be inserted into the two slots 1111 one-to-one along the first direction Z. The wall surfaces of the fasteners 122 and the wall surfaces of the slots 1111 are correspondingly arranged to absorb assembly gaps. After the two fasteners 122 are correspondingly fastened into the two slots 1111, the external force causes the metal decorative piece 120 to detach from the base 110 in the XY plane. The fasteners 122 will abut against the wall surface of the slots 1111 and be limited, and the metal decorative piece 120 is not easily detached from the base 110 along the vertical direction of the first direction (e.g., X direction, Y direction).

[0172] See Figure 12A The buckle 122 and the covering part 121 can be an integral structure. One end of the buckle 122 is connected to the first end 121a of the covering part 121, and the side of the buckle 122 is connected to the inner surface of the covering part 121, so that the buckle 122 and the covering part 121 are reliably connected. For example, it can be machined using a CNC machine tool. Alternatively, the buckle 122 and the covering part 121 can be independent parts, and they are fixed by welding. Using the above methods, the buckle 122 and the covering part 121 of the metal decorative part 120 are easy to process.

[0173] In some embodiments, see Figure 12AThe covering portion 121 extends along the second direction A; a plurality of fasteners 122 are arranged along the second direction A. The second direction A is a direction within the XY plane, and can extend as a straight line or an arc. The covering portion 121 is configured as a strip structure extending along the second direction. By providing two or more fasteners 122, the metal decorative piece 120 can be reliably positioned on the base 110.

[0174] In some embodiments, see Figure 13 , Figure 14A , Figure 14B , Figure 14C The slot 1111 can be a through slot, extending through both the front side 111a and the back side 111b. Alternatively, the slot 1111 can be a recess on the front side 111a, extending along the first direction Z. Both the recess and the through slot can engage with the buckle 122 to limit the metal decorative part 120 to the base 110 along the vertical direction of the first direction (e.g., X-axis, Y-axis). When machining the slot 1111 on the base 110, it can be manufactured using laser processing (e.g., laser engraving), CNC machine tool processing, or direct forming of the blank.

[0175] In some embodiments, the number of limiting portions 123 can be one or more. For example, see [reference needed]. Figure 14A , Figure 14B The limiting part 123 is one, and the limiting part 123 can extend along the second direction A. The limiting part 123 can be disposed in the middle of the second end 121b of the covering part 121. Alternatively, refer to Figure 16A , Figure 16B There are two limiting parts 123, which are provided at opposite ends of the second end 121b of the covering part 121.

[0176] It should be noted that, Figures 4 to 9 , Figures 11 to 15 The following description uses the example of a metal decorative element 120 being disposed on the bezel, but the embodiments of this application are not limited thereto.

[0177] The third method for implementing the buckle 122 and slot 1111 is described below.

[0178] In some embodiments, see Figures 17 to 20A The fastener 122 includes a first portion 1221 and a second portion 1222. The first portion 1221 extends along a first direction Z and connects between the first end 121a of the covering portion 121 and the second portion 1222. The width d1 of the first portion 1221 is smaller than the width d2 of the second portion 1222. The slot 1111 has an undercut 1112. The fastener 122 is assembled in the slot 1111 along the first direction Z, and the second portion 1222 is fastened to the undercut 1112 to limit the metal decorative piece 120 to the base 110.

[0179] The width d1 of the first part 1221 is the minimum dimension of the first part 1221 in the third direction B. The width d2 of the second part 1222 is the minimum dimension of the second part 1222 in the third direction B. The third direction B is a direction in the XY plane, such as the radial direction of the base 110 or a direction parallel to the radial direction of the base 110. The aforementioned buckle 122 can be called a horseshoe buckle or a T-shaped buckle.

[0180] The fastener 122 is fastened to the groove 1111 of the base 110 along the first direction Z, which can limit the metal decorative part 120 on the base 110 and reduce the possibility of the metal decorative part 120 detaching from the base 110 in the vertical direction (such as the X direction or the Y direction) of the first direction.

[0181] On the cross section passing through the buckle 122, the covering part 121 and the limiting part 123, the buckle 122, the covering part 121 and the limiting part 123 can be arranged in a roughly C-shape. The C-shaped structure is clamped at the edge of the base 110 and fastened to the groove 1111 by the buckle 122. The limiting part 123 is provided on the back side 111b of the mounting position 111, so that the metal decorative part 120 is limited to the base 110.

[0182] The buckle 122 and the covering part 121 can be an integral structure. For example, they can be machined using a CNC machine tool. Alternatively, the buckle 122 and the covering part 121 can be separate parts, which are fixed together by welding. Using the above methods, the buckle 122 and the covering part 121 of the metal decorative part 120 are easy to process.

[0183] In some embodiments, see Figure 19 On the vertical plane (XY plane) in the first direction, the projection of the inverted 1112 is U-shaped. (Combined with...) Figure 18A , Figure 20A The buckle 122, which has a first part 1221 and a second part 1222, is inserted into the slot 1111, so that the second part 1222 is fastened to the U-shaped buckle 1112. This allows the metal decorative part 120 to be limited to the base 110 along the first direction Z and the direction perpendicular to the first direction (such as the X direction and the Y direction), and the metal decorative part 120 is not easy to detach from the base 110.

[0184] For example, the opening of the U-shaped buckle 1112 may be positioned facing the outer edge of the base 110. The second portion 1222 of the buckle 122 is inserted through the opening of the buckle 1112, so that the second portion 1222 and the buckle 1112 are fastened together. The adhesive 130 is applied by dispensing, and the adhesive 130 may be filled between the surfaces of the buckle 122 and the groove 1111, and also between the inner surface of the covering portion 121 and the outer peripheral surface 111c of the mounting position 111, so that the metal decorative piece 120 is reliably fixed to the mounting position 111.

[0185] In some embodiments, see Figure 18A , Figure 18B , Figure 20A The covering portion 121 and the limiting portion 123 are an integral structure, with the limiting portion 123 bent to cover the bottom edge 110b of the base 110. This reliably fixes the metal decorative piece 120 to the base 110. This method is suitable for scenarios where the limiting portion 123 is not obstructed by other components, and the connection between the limiting portion 123 and the covering portion 121 has a good aesthetic effect and minimal impact on the overall appearance. Figure 20B , Figure 20C The limiting part 123 can be bent once relative to the covering part 121, combined with Figure 20A The limiting part 123 itself can be bent once, so that the limiting part 123 stably covers the bottom edge 110b of the substrate 110.

[0186] In some embodiments, see Figure 21 The bending position of the limiting part 123 has a bending groove 1231. The bending groove 1231 is provided to facilitate the bending of the limiting part 123 to cover the second end 121b of the substrate 110.

[0187] In other embodiments, see Figure 20A When the covering part 121 and the limiting part 123 are not connected, they are independent parts. After the covering part 121 is fixed to the mounting position 111 using adhesive 130, the limiting part 123 and the back surface 111b are bonded together. The limiting part 123 can be pre-fixed using spot adhesive or back adhesive. The second end 121b of the covering part 121 and the limiting part 123 are welded together. The welding and fixing of the covering part 121 and the limiting part 123 are achieved by laser spot welding and melting gold wire. This method is suitable for scenarios where the limiting part 123 is obstructed by other components, and the welding process is easy to implement.

[0188] In some embodiments, the second portion 1222 of the buckle 122 can be configured with different shapes, such that the buckle 122 is assembled into the slot 1111 along the first direction Z, the second portion 1222 is fastened to the undercut 1112, and the metal decorative piece 120 is limited to the base 110. For example, see Figure 18A , Figure 21 In the vertical plane (XY plane) of the first direction, the second part 1222 is circular. (See reference...) Figure 21 Alternatively, in the vertical plane (XY plane) of the first direction, the second part 1222 can be a rectangle extending along the third direction B.

[0189] In some embodiments, see Figure 18A , Figure 20A Each fastener 122 is a single fastener. A single fastener 122 is fastened to the groove 1111 of the base 110, which enables the metal decorative piece 120 to be positioned on the base 110.

[0190] In other embodiments, see Figures 23 to 25 The covering portion 121 extends along the second direction A; there are multiple fasteners 122, which are arranged along the second direction A. The second direction A is a direction within the XY plane, and can be a straight line or an arc. The covering portion 121 is configured as a strip structure extending along the second direction A. By providing two or more fasteners 122, the metal decorative part 120 can be reliably positioned on the base 110. The fasteners 122 and the slots 1111 of the base 110 can be provided in a one-to-one correspondence.

[0191] For example, the first end 121a of the covering portion 121 is provided with two buckle portions 122 that are spaced apart along the second direction A. The buckle portions 122 have a small size along the second direction A, so that the metal decorative piece 120 is reliably fixed on the base 110, thereby reducing the cost of using precious metals in the buckle portions 122.

[0192] In some embodiments, see Figure 19 The groove 1111 can be a recess located on the front side 111a, extending along the first direction Z. Alternatively, the groove 1111 can be a through groove extending through both the front side 111a and the back side 111b. Both the recess and the through groove can engage with the fastener 122 to limit the metal decorative piece 120 to the base 110 along the direction perpendicular to the first direction (e.g., X-axis, Y-axis). When machining the groove 1111 on the base 110, it can be manufactured using laser processing, CNC machine tool processing, or direct forming of the blank.

[0193] In some embodiments, the number of limiting portions 123 can be one or more. For example, see [reference needed]. Figure 24 There is one limiting part 123, which can extend along the second direction A and can be disposed in the middle of the second end 121b of the covering part 121. Alternatively, there are two limiting parts 123, which are disposed at opposite ends of the second end 121b of the covering part 121.

[0194] It should be noted that, Figures 17 to 22 , Figures 23-25 The description uses a metal decorative component 120 disposed on the middle frame as an example, but the embodiments of this application are not limited to this. It is understood that the above-described decorative component 100 can be applied to, for example... Figure 2 The wearable device 1000 shown can also be applied to other devices, such as mobile phones and tablets, to enable the metal decorative parts 120 to be set at predetermined positions on different product shells.

[0195] To confirm whether it is the decorative component 100 and wearable device 1000 of this application embodiment, the wearable device 1000 can be disassembled, and the decorative component 100 can be observed, sliced, or subjected to computed tomography scan to confirm that the substrate 110 has a mounting position 111 for mounting the metal decorative part 120. The mounting position 111 has a front side 111a and a back side 111b facing each other, and an outer peripheral surface 111c located between the front side 111a and the back side 111b. The front side 111a has a groove 1111. The metal decorative part 120 includes a covering portion 121, a fastening portion 122, and a limiting portion 123. The fastening portion 122 is connected to the first end 121a of the covering portion 121, and the limiting portion 123 is connected to the second end 121b of the covering portion 121. The fastening portion 122 is fastened to the groove 1111, the covering portion 121 at least covers the mounting position 111, and the limiting portion 123 is provided on the back side 111b. The inner surface of the metal decorative part 120 and the mounting position 111 are bonded together by adhesive 130.

[0201] The second end 121b of the covering part 121 and the limiting part 123 are welded together to form a metal decorative part 120.

[0202] This application provides a method for manufacturing a decorative component 100. A decorative component is provided at the mounting position 111 of the base 110. The covering part 121 of the decorative component covers the mounting position 111, the fastening part 122 is fastened to the groove 1111 on the front side 111a of the mounting position 111, and the limiting part 123 is provided on the back side 111b of the mounting position 111, thereby physically limiting the metal decorative component 120. The decorative component and the mounting position 111 are bonded together with an adhesive 130, thereby completely fixing the decorative component to the base 110. During long-term use, or under the influence of external environments such as temperature, humidity, or corrosive liquids, the metal decorative component 120 is physically limited and is not easily detached from the base 110, resulting in good connection reliability between the metal decorative component 120 and the base 110.

[0203] It is understood that the previous embodiments of the decorative component 100 can be applied to the manufacturing method of the decorative component 100 in the embodiments of this application, and will not be repeated here.
