[0031] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0032] At present, in order to improve the aesthetics of wearable devices, decorative parts are often set on the middle frame of the wearable devices. The removal and installation of the decorative parts may be very frequent. In addition, when removing and installing the decorative parts, the decorative parts are easily collided with the middle frame body to cause wear, which makes the overall wear resistance of the middle frame assembly poor, thereby reducing the service life of the wearable device.

[0033] In order to solve the above technical problems, the present disclosure provides a middle frame assembly and a wearable device. By providing a first clamping portion on the decorative piece and a second clamping portion cooperating with the first clamping portion on the middle frame body, the decorative piece can be detachably installed on the middle frame body, which facilitates the disassembly and installation of the decorative piece. At the same time, since an auxiliary piece in contact with the first clamping portion is provided, wear of the middle frame body during disassembly and installation of the decorative piece can be avoided, thereby improving the wear resistance of the middle frame assembly.

[0034] According to an exemplary embodiment, Figure 1-Figure 4 As shown, the embodiment of the present disclosure provides a middle frame assembly, which can be applied to wearable devices such as smart watches and smart bracelets. In the embodiment of the present disclosure, the structure of the middle frame assembly is described by taking a smart watch as an example. The middle frame assembly includes a middle frame body 10, a decorative part 20 and an auxiliary part 111. The material of the middle frame body 10 can be, for example, aluminum alloy, titanium alloy or other materials with good aesthetics, light weight, excellent corrosion resistance and heat resistance, so as to reduce the overall quality of the middle frame assembly and the wearable device and improve the wearing feeling of the user.

[0035] In the disclosed embodiment, the overall shape of the middle frame body 10 is roughly a ring, and a connection portion for the user to configure a watch strap is provided on the middle frame body 10. When the wearable device is in other shapes, the shape of the middle frame body 10 can also be adaptively adjusted. The middle frame body 10 has an installation area 103, and the installation area 103 is used to install the decorative part 20. The area of ​​the installation area 103 can be less than or equal to the area of ​​the middle frame body 10. Among them, the material of the decorative part 20 can be different from the material of the middle frame body 10. For example, in order to reduce the overall weight of the middle frame assembly and reduce the production cost, the decorative part 20 can be made of lightweight materials such as plastic and silicone. For example, in order to improve the overall aesthetics of the middle frame assembly, the decorative part 20 can be made of glass, synthetic resin and other materials, and a coating or plating decoration can also be provided on the surface of the decorative part 20. By replacing the decorative part 20 on the middle frame body 10, the personalization of the wearable device can be enhanced, reflecting the distinctive personal characteristics of the user.

[0036] The decorative member 20 is installed in the installation area 103. The decorative member 20 includes a first clamping portion (specifically, a clamping spring 22 described later). The installation area 103 is provided with a second clamping portion 11 clamped and connected with the first clamping portion, and a part of the second clamping portion 11 is provided as an auxiliary member 111. The auxiliary member 111 can be an independent structure fixed on the second clamping portion 11. The auxiliary member 111 is embedded in the edge of the middle frame body 10, and at least part of the auxiliary member 111 protrudes from the edge of the middle frame body 10. The auxiliary member 111 is used to contact and connect with the first clamping portion to reduce the collision and wear between the first clamping portion and the middle frame body 10. When the first clamping portion is clamped and connected with the second clamping portion 11, the first clamping portion is in contact and connected with the auxiliary member 111, so that the decorative member 20 can be detachably installed in the installation area 103. The auxiliary part 111 provided in the present disclosure is used as a structure that mainly contacts the decorative part 20 during the process of disassembling and assembling the decorative part 20, so as to avoid the wear of the middle frame body 10 caused by the frequent replacement of the decorative part 20. Therefore, the material of the auxiliary part 111 should be selected as a wear-resistant material with a relatively large hardness as much as possible, and the auxiliary part 111 is set as a structure independent of the middle frame body 10, so that when the auxiliary part 111 is seriously worn, it can be replaced without replacing the entire middle frame body 10, and the after-sales cost of the user is reduced. Of course, it is understandable that in some possible embodiments, the auxiliary part 111 and the middle frame body 10 can also be set as an integral structure, and a wear-resistant layer can be set on the outer surface of the auxiliary part 111. During the disassembly and assembly of the decorative part 20, the wear-resistant layer contacts the decorative part 20, so as to avoid the contact friction between the middle frame body 10 and the decorative part 20 and cause wear.

[0037] It can be understood that in the embodiment of the present disclosure, the number of the first clamping parts and the second clamping parts 11 are both two, which are arranged at the radial ends of the middle frame assembly, so as to realize the fixation between the middle frame body 10 and the decorative part 20. In the actual production process, the number of the first clamping parts and the second clamping parts 11 can also be increased according to actual needs to improve the reliability of the connection between the decorative part 20 and the middle frame body 10. The embodiment of the present disclosure does not impose too many restrictions on this.

[0038] In the disclosed embodiment, a decorative piece is provided in the middle frame assembly to improve the overall aesthetics. By providing a first clip portion on the decorative piece and providing a second clip portion on the middle frame body that cooperates with the first clip portion, the decorative piece can be detachably installed on the middle frame body, which facilitates the disassembly and installation of the decorative piece. At the same time, since part of the second clip portion is provided as an auxiliary piece, the first clip portion is in contact and connected with the auxiliary piece, which can avoid wear of the decorative piece and the middle frame body when disassembling and installing the decorative piece, thereby improving the wear resistance of the middle frame assembly and enhancing the user experience.

[0039] In some embodiments, Figure 4 As shown, the auxiliary component 111 is an independent structure fixed on the second clamping portion 11. A mounting groove 12 is provided on the edge of the middle frame body 10, and the auxiliary component 111 is fixed in the mounting groove 12 by welding or bonding. The mounting groove 12 is used to cooperate with the auxiliary component 111, and the shape of the mounting groove 12 is adapted to the shape of the auxiliary component 111 to improve the tightness and stability of the connection between the auxiliary component 111 and the middle frame body 10. For example, when the auxiliary component 111 is a cylinder, the mounting groove 12 is a cylindrical groove, and when the auxiliary component 111 is a prism, the mounting groove 12 is a prismatic groove. Of course, the auxiliary component 111 can also be set to other irregular shapes, and the shape of the auxiliary component 111 can be matched with the first clamping portion. The disclosed embodiment does not impose too many restrictions on this. Among them, the edge of the middle frame body 10 is the outer edge, that is, the side of the middle frame body 10 away from the center of the wearable device, with Figure 4 Taking the orientation shown in FIG. 1 as an example, the mounting groove 12 is arranged on the left edge of the middle frame body 10 .

[0040] In some embodiments, Figure 1-Figure 4 As shown, the middle frame body 10 is provided with a first protrusion 13, and a recessed portion 14 is formed between the first protrusion 13 and the auxiliary component 111. The first clamping portion of the decorative component 20 includes a second protrusion 211. When the decorative component 20 is installed in the installation area 103, the second protrusion 211 abuts against the auxiliary component 111, and the second protrusion 211 is clamped into the recessed portion 14, thereby improving the stability of the connection between the middle frame body 10 and the decorative component 20.

[0041] In some embodiments, Figure 2-Figure 4As shown, the decorative member 20 includes a body 21 and a snap-on spring piece 22, and the snap-on spring piece 22 is disposed on a side of the body 21 close to the middle frame body 10. The snap-on spring piece 22 includes a first end 221, a second end 222, and a connecting portion 223, and the connecting portion 223 is located between the first end 221 and the second end 222, and the connecting portion 223 is bent toward the direction close to the middle frame body 10 to form a second protrusion 211. The snap-on spring piece 22 can produce a certain elastic deformation, so as to ensure that the snap-on spring piece 22 is easy to disassemble when being snap-oned with the middle frame body 10. When the decorative piece 20 is installed on the middle frame body 10, the second protrusion 211 abuts against the recessed portion 14, pressing the middle frame body 10 to prevent the decorative piece 20 from coming off the middle frame body 10. When the decorative piece 20 is removed, an external force acts on the snap-on spring piece 22, causing the snap-on spring piece 22 to deform in a direction away from the recessed portion 14, and the friction between the snap-on spring piece 22 and the middle frame body 10 disappears, and the decorative piece 20 is removed from the middle frame body 10. The first end 221 and the second end 222 of the snap-on spring piece 22 are respectively fixedly connected to the body 21, and the fixed connection method can be welding, bonding, etc. The embodiment of the present disclosure does not impose too many restrictions on the specific connection method between the first end 221 and the second end 222 and the body 21.

[0042] In some embodiments, Figure 4 As shown, the height of the auxiliary member 111 protruding from the edge of the middle frame body 10 is greater than the height of the first protrusion 13 protruding from the middle frame body 10. Since the height of the auxiliary member 111 protruding from the edge of the middle frame body 10 is greater than the height of the first protrusion 13 protruding from the middle frame body 10, the main contact part between the first clamping part of the decorative member 20 and the middle frame body 10 is the auxiliary member 111, which can reduce the collision between the decorative member 20 and the first protrusion 13, thereby improving the wear resistance of the middle frame assembly.

[0043] In some embodiments, a first wear-resistant layer is disposed on the outer surface of the first protrusion 13; and / or the first protrusion 13 and the middle frame body 10 are an integral structure.

[0044] In one example, a first wear-resistant layer is provided on the outer surface of the first protrusion 13. The material of the first wear-resistant layer is a wear-resistant material, specifically wear-resistant rubber, high-chromium cast iron, manganese steel alloy, polymer wear-resistant material and the like, so as to improve the wear resistance of the first protrusion 13 and reduce collision damage. The first wear-resistant layer can be provided on the outer surface of the first protrusion 13 by bonding, welding, fastening connection, plating or other methods, and the embodiments of the present disclosure do not impose too many restrictions on this.

[0045] In another example, the first protrusion 13 and the middle frame body 10 are an integral structure, and the middle frame body 10 can be made of a material with high strength, excellent corrosion resistance and heat resistance, such as aluminum alloy and titanium alloy.

[0046] In another example, the first protrusion 13 and the middle frame body 10 are an integral structure, and a first wear-resistant layer is provided on the outer surface of the first protrusion 13, thereby further improving the wear resistance of the first protrusion 13 and improving the wear resistance and service life of the middle frame assembly.

[0047] In some embodiments, the Rockwell hardness of the material of the auxiliary part 111 is greater than the Rockwell hardness of the material of the middle frame body 10; and / or, a second wear-resistant layer is provided on the outer surface of the auxiliary part 111. Since the auxiliary part 111 is the main part of the middle frame body 10 that contacts the first clamping part, it is necessary to improve the wear resistance of the auxiliary part 111 to reduce wear and extend the service life of the middle frame assembly. Among them, the Rockwell hardness is usually used to measure the hardness value of materials with higher hardness. It is obtained by using a 150kg load and a diamond cone indenter. It is an indicator that determines the hardness value by the depth of plastic deformation of the indentation, and the range is 20 to 70HRC. The material of the auxiliary part 111 can be stainless steel. Preferably, the Rockwell hardness of the stainless steel material is greater than 30HRC.

[0048] In one example, the Rockwell hardness of the material of the auxiliary component 111 is greater than the Rockwell hardness of the material of the middle frame body 10 , and the wear resistance of the auxiliary component 111 is improved by setting the material of the auxiliary component 111 to be a wear-resistant material.

[0049] In another example, a second wear-resistant layer is provided on the outer surface of the auxiliary part 111, and the material of the first wear-resistant layer is a wear-resistant material, specifically, wear-resistant rubber, high chromium cast iron, manganese steel alloy, polymer wear-resistant material and the like, so as to improve the wear resistance of the surface of the auxiliary part 111. Since only one layer of wear-resistant material is provided on the outer surface, the production cost can be reduced while ensuring the wear resistance.

[0050] In another example, the Rockwell hardness of the material of the auxiliary part 111 is greater than the Rockwell hardness of the material of the middle frame body 10, and a second wear-resistant layer is provided on the outer surface of the auxiliary part 111, thereby further improving the wear resistance of the auxiliary part 111 and reducing the collision wear between the auxiliary part 111 and the first clamping part.

[0051] In some embodiments, Figure 1-Figure 4 As shown, the middle frame body 10 includes an inner ring 101 and an outer ring 102. Figure 3Taking the orientation shown in as an example, the bottom surface of the inner ring 101 and the bottom surface of the outer ring 102 are located in the same plane, the top surface of the inner ring 101 is higher than the top surface of the outer ring 102, and the area between the top surface of the outer ring 102 and the top surface of the inner ring 101 constitutes the installation area 103, the area of ​​the installation area 103 is smaller than the area of ​​the middle frame body 10, and the auxiliary part 111 is arranged at the outer edge of the inner ring 101. The side of the decorative part 20 that contacts the middle frame body 10 is provided with a first avoidance portion 201 and a second avoidance portion 202, the first avoidance portion 201 cooperates with the inner ring 101, and the second avoidance portion 202 cooperates with the outer ring 102, so that the decorative part 20 is buckled on the middle frame body 10.

[0052] In some embodiments, the inner ring 101 includes an aluminum alloy ring body, and the auxiliary part 111 includes a stainless steel cylinder. The material of the inner ring 101 can be the same as or different from that of the outer ring 102. Preferably, the inner ring 101 and the outer ring 102 are an integral structure, and the outer ring 102 is an aluminum alloy ring body integrally connected to the inner ring 101. Of course, it can be understood that the materials of the inner ring 101 and the outer ring 102 can also include titanium alloy, manganese steel alloy, etc., and the embodiments of the present disclosure do not impose too many restrictions on this. The auxiliary part 111 can include a stainless steel cylinder. Of course, it can be understood that the material of the auxiliary part 111 can also be high chromium cast iron, wear-resistant rubber, polymer wear-resistant material, etc. The shape of the auxiliary part 111 can include but is not limited to a cylinder, a triangular prism, a quadrangular prism, etc. The embodiments of the present disclosure do not impose too many restrictions on the material and shape of the auxiliary part 111, as long as it can contact with the first clamping portion, thereby reducing the direct wear between the middle frame body 10 and the decorative part 20.

[0053] According to an exemplary embodiment, the embodiment of the present disclosure provides a wearable device. In the embodiment of the present disclosure, a smart watch is taken as an example. Of course, it can be understood that the wearable device may include but is not limited to a smart watch, a smart bracelet, etc. The wearable device includes a device body and a middle frame assembly as described in the above embodiment, and the middle frame assembly is arranged on the device body.

The decorative part 20 includes a first clamping part, and the installation area 103 is provided with a second clamping part 11 that is clamped and connected with the first clamping part. A part of the second clamping part 11 is set as an auxiliary part 111, and the auxiliary part 111 is embedded in the edge of the middle frame body 10, and at least part of the area of ​​the auxiliary part 111 protrudes from the edge of the middle frame body 10. The auxiliary part 111 is used to contact and connect with the first clamping part to reduce the collision and wear between the first clamping part and the middle frame body 10. When the first clamping portion is clamped and connected with the second clamping portion 11 , the first clamping portion is in contact and connected with the auxiliary component 111 , so that the decorative component 20 is detachably installed in the installation area 103 .
