[0037] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0038] The embodiment of the present application provides an electronic device, which may be an electronic product such as a smart watch or a smart bracelet, or a camera module disposed on the back of a mobile phone or a tablet computer. The embodiment of the present application does not limit this.

[0039] Please refer to Figure 1 and Figure 2 , Figure 1 is a three-dimensional schematic diagram of an electronic device provided in an embodiment of the present application, Figure 2 yes Figure 1 The electronic device 000 may include: a device body 100 , an inner ring portion 200 , an outer ring portion 300 and an elastic limiting ring 400 .

[0040] The inner ring portion 200 in the electronic device 000 can be sleeved on the device body 100 in the electronic device 000 and connected to the edge portion of the device body 100 . The inner ring portion 200 in the electronic device 000 can have a first clamping component 201 .

[0041] The outer ring portion 300 in the electronic device 000 can be sleeved on the inner ring portion 200 in the electronic device 000 and is rotatably connected to the inner ring portion 200 in the electronic device 000. In order to more clearly see the shape of the outer ring portion 300 in the electronic device 000, please refer to Figure 3 , Figure 3 It is a schematic diagram of the three-dimensional structure of an outer ring portion provided in an embodiment of the present application. The outer ring portion 300 in the electronic device 000 may have a second clamping component 301.

[0042] Here, the inner ring portion 200 and the outer ring portion 300 in the electronic device 000 can both be circular ring structures, the edge portion of the device body 100 can also be a circular structure, and the axis line of the inner ring portion 200, the axis line of the outer ring portion 300 and the axis line of the edge portion of the device body 100 can coincide.

[0043] It should be noted that the inner ring 200 can be screwed onto the edge of the device body 100. For example, the inner ring 200 can have an internal thread, and the edge of the device body 100 can have an external thread, so that the inner ring 200 and the edge of the device body 100 can be connected together by a threaded connection.

[0044] The elastic limiting ring 400 in the electronic device 000 can be sleeved on the inner ring part 200, and the elastic limiting ring 400 can be distributed between the inner ring part 200 and the outer ring part 300. Here, the elastic limiting ring 400 in the electronic device 000 can be connected to the inner ring part 200, and the elastic limiting ring 400 can be abutted against the outer ring part 300 in a direction parallel to the axis of the inner ring part 200. Here, by arranging the elastic limiting ring 400 between the inner ring part 200 and the outer ring part 300, it can be ensured that the outer ring part 300 is not easy to fall off from the inner ring part 200.

[0045] Among them, after the outer ring part 300 is subjected to an external pulling force in a direction away from the inner ring part 200, the outer ring part 300 in the electronic device 000 can move in a direction away from the inner ring part 200, so that the first clamping part 201 in the inner ring part 200 can be clamped with the second clamping part 301 in the outer ring part 300.

[0046] In the embodiment of the present application, since the outer ring part 300 in the electronic device 000 is not subjected to the pulling force in the direction away from the inner ring part 200, the first clamping member 201 of the inner ring part 200 and the second clamping member 301 of the outer ring part 300 are separated in the direction parallel to the axis of the inner ring part 200. Therefore, the outer ring part 300 sleeved on the inner ring part 200 can rotate relative to the inner ring part 200 after receiving the rotational driving force applied from the outside. That is, after the outer ring part 300 and the inner ring part 200 are installed on the device body 100, the outer ring part 300 can rotate relative to the device body 100 after receiving the rotational driving force applied from the outside, thereby enriching the functions of the electronic device 000.

[0047] When the outer ring 300 in the electronic device 000 is subjected to a pulling force in a direction away from the inner ring 200, the outer ring 300 can move in a direction away from the inner ring 200, so that the first clamping member 201 of the inner ring 200 and the second clamping member 301 of the outer ring 300 are clamped. After the outer ring 300 is subjected to a rotational driving force applied from the outside, the outer ring 300 can rotate together with the inner ring 200. Since the inner ring portion 200 is connected to the edge portion of the device body 100 by threads, when the outer ring portion 300 is subjected to an external rotational driving force so that the outer ring portion 300 rotates together with the inner ring portion 200, the inner ring portion 200 can be screwed into the edge portion of the device body 100 or screwed out from the edge portion of the device body 100, thereby realizing the installation of the outer ring portion 300 and the inner ring portion 200 on the device body 100, or the removal of the outer ring portion 300 and the inner ring portion 200 from the device body 100.

[0048] To this end, the electronic device 000 provided in the present application can not only facilitate users to install the outer ring portion 300 and the inner ring portion 200 on the device body 100, or remove the outer ring portion 300 and the inner ring portion 200 from the device body 100, but also allow users to freely rotate the outer ring portion 300, thereby enriching the functions of the electronic device 000.

[0049] In summary, an embodiment of the present application provides an electronic device, which may include: a device body, an inner ring, an outer ring, and an elastic limit ring. When the outer ring in the electronic device is not subjected to a pulling force in the direction away from the inner ring, the first clamping part of the inner ring and the second clamping part of the outer ring are separated in a direction parallel to the axis of the inner ring. Therefore, the outer ring sleeved on the inner ring can rotate relative to the inner ring after being subjected to an externally applied rotational driving force. That is, after the outer ring and the inner ring are installed on the device body, the outer ring can rotate relative to the device body after being subjected to an externally applied rotational driving force, thereby enriching the functions of the electronic device. In the case where the outer ring portion in the electronic device is subjected to a pulling force in the direction away from the inner ring portion, after the outer ring portion is subjected to an externally applied rotational driving force, the outer ring portion can rotate together with the inner ring portion, so that during the process of rotating the outer ring portion and the inner ring portion together, the inner ring portion can be screwed into the edge portion of the device body, or can be screwed out from the edge portion of the device body, thereby realizing the installation of the outer ring portion and the inner ring portion on the device body, or the removal of the outer ring portion and the inner ring portion from the device body. The electronic device provided by the present application can not only facilitate users to install the outer ring portion and the inner ring portion on the device body, or remove the outer ring portion and the inner ring portion from the device body, but also allow users to freely rotate the outer ring portion, thereby enriching the functions of the electronic device.

[0050] In the examples of this application, please refer to Figure 4 and Figure 5 , Figure 4 is a schematic diagram of a three-dimensional structure of an elastic limiting ring provided in an embodiment of the present application, Figure 5 yes Figure 4 The elastic limiting ring 400 in the electronic device 000 may include: a limiting ring body 401 and a fixing protrusion 402 connected to the limiting ring body 401 .

[0051] It should be noted that if Figure 6 and Figure 7 As shown, Figure 6 is a partial cross-sectional view of an electronic device provided in an embodiment of the present application, Figure 7 It is a partial cross-sectional view of another electronic device provided by an embodiment of the present application. In the direction perpendicular to the axis of the inner ring portion 200, the width d1 of the clamping protrusion 402 can be greater than the width d2 of the limiting ring body 401. For this reason, the clamping protrusion 402 refers to: the part of the elastic limiting ring 400 that protrudes outward relative to the limiting ring body 401 in the direction perpendicular to the axis of the inner ring portion 200.

[0052] Please refer to Figure 6 In a direction perpendicular to the axis of the inner ring portion 200 in the electronic device 000 , the outer ring portion 300 in the electronic device 000 may have a first annular groove C1 on one side facing the inner ring portion 200 .

[0053] Among them, the limiting ring body 401 in the elastic limiting ring 400 can be sleeved on the inner ring part 200 in the electronic device 000, and at least part of the fixing protrusion 402 of the elastic limiting ring 400 can be located in the first annular groove C1 in the outer ring part 300.

[0054] In this case, after the fixing protrusion 402 in the elastic limiting ring 400 is inserted into the first annular groove C1 of the outer ring portion 300 , it can ensure that the outer ring portion 300 is not easy to fall off from the inner ring portion 200 .

[0055] In the examples of this application, please refer to Figure 4 and Figure 5 The elastic limiting ring 400 in the electronic device 000 may include a plurality of fixing protrusions 402, and the plurality of fixing protrusions 402 may be distributed around the axis of the inner ring portion 200. In this way, the plurality of fixing protrusions 402 can reliably fix the outer ring portion 300 on the inner ring portion 200, and the plurality of fixing protrusions 402 can also make the force on the outer ring portion 300 more uniform. It should be noted that the plurality of fixing protrusions 402 can be evenly distributed around the axis of the inner ring portion 200. The embodiment of the present application does not limit this.

[0056] In the examples of this application, please refer to Figure 6 and Figure 7 In the direction parallel to the axis of the inner ring 200, the width d3 of the limit ring body 401 in the elastic limit ring 400 is greater than the width d4 of the clamping protrusion 402 in the elastic limit ring 400. In this way, on the one hand, it can ensure that the elastic limit ring 400 is reliably installed on the inner ring 200, and on the other hand, it can ensure that when the outer ring 300 is subjected to a pulling force in a direction away from the inner ring 200 and moves in a direction away from the inner ring 200, the clamping protrusion 402 in the elastic limit ring 400 can easily undergo torsional deformation.

[0057] It should be noted that the elastic limiting ring 400 can be made of a metal material with elastic deformation ability, so that the elastic limiting ring 400 can be formed into a limiting ring body 401 and a fixing protrusion 402 by a stamping process, and the limiting ring body 401 and the fixing protrusion 402 can be arranged alternately, thereby simplifying the production process of the elastic limiting ring 400. In other embodiments, the limiting ring body 401 can also be made of a plastic material with elastic deformation ability, so that the elastic limiting ring 400 can be integrally formed into the limiting ring body 401 and the fixing protrusion 402 by an injection molding process. The embodiment of the present application does not limit this.

[0058] In the examples of this application, please refer to Figure 6 , in the direction perpendicular to the axis of the inner ring part 200, the inner ring part 200 in the electronic device 000 may have a second annular groove C2 on one side facing the outer ring part 300 in the electronic device 000, and at least part of the limiting ring body 401 may be located in the second annular groove C2. In this case, the second annular groove C2 on the inner ring part 200 can accurately position the elastic limiting ring 400 and ensure that the elastic limiting ring 400 is not easy to fall off from the inner ring part 200. In this case, a part of the elastic limiting ring 400 can be inserted into the first annular groove C1, and another part of the elastic limiting ring 400 can be inserted into the second annular groove C2. In this way, through the first annular groove C1 and the second annular groove C2, and the elastic limiting ring 400 clamped therebetween, it can be ensured that the outer ring part 300 sleeved on the inner ring part 200 is not easy to fall off from the inner ring part 200.

[0059] In the examples of this application, please refer to Figure 4 , the limiting ring body 401 in the electronic device 000 may have a break K1.

[0060] In this case, on the one hand, when the elastic limit ring 400 in the electronic device 000 is sleeved on the inner ring part 200 in the electronic device 000, the fracture K1 of the limit ring body 401 can be beneficial to the expansion and deformation of the elastic limit ring 400, so that the elastic limit ring 400 in the electronic device 000 is easily sleeved on the inner ring part 200 in the electronic device 000; on the other hand, when the outer ring part 300 in the electronic device 000 is installed on the inner ring part 200 in the electronic device 000, the fracture K1 of the limit ring body 401 can be beneficial to the contraction and deformation of the elastic limit ring 400, so that the outer ring part 300 is easily sleeved on the inner ring part 200.

[0061] Furthermore, after the outer ring portion 300 in the electronic device 000 is sleeved onto the inner ring portion 200 in the electronic device 000, under the action of the restoring force of the elastic limit ring 400 in the electronic device 000, the elastic limit ring 400 restores its deformation, so that the fixing protrusion 402 of the elastic limit ring 400 is inserted into the first annular groove C1 of the outer ring portion 300, thereby preventing the outer ring portion 300 from falling off the inner ring portion 200.

[0062] In the examples of this application, please refer to Figure 8 and Fig. 9 , Figure 8 is a three-dimensional diagram of an inner ring portion of an electronic device provided in an embodiment of the present application; Fig. 9 yes Figure 8 A partial enlarged view of B in the figure. In a direction parallel to the axis of the inner ring 200 of the electronic device 000 , the inner ring 200 of the electronic device 000 may have a first clamping member 201 and at least one elastic contact 202 on one side facing the outer ring 300 .

[0063] Please refer to Fig.10 and Fig.11 , Fig.10 is a three-dimensional diagram of the outer ring portion of another electronic device provided in an embodiment of the present application, Fig.11 yes Fig.10 A partial enlarged view of the portion C in the middle. The outer ring portion 300 of the electronic device 000 may have a second clamping member 301 and a plurality of grooves C3 on one side thereof facing the inner ring portion 200 of the electronic device 000 .

[0064] The plurality of grooves C3 on the outer ring portion 300 may be distributed around the axis of the inner ring portion 200 , and the elastic contacts 202 on the inner ring portion 200 may be located in any groove C3 .

[0065] In this case, after the outer ring part 300 is installed on the inner ring part 200, the elastic contact 202 on the inner ring part 200 can abut against the side of the outer ring part 300 facing the inner ring part 200. When the outer ring part 300 is subjected to the rotational driving force applied from the outside, the elastic contact 202 can slide into the groove C3 and can slide out of the groove C3. Here, after the elastic contact 202 slides into the groove C3, the elastic contact 202 will apply a force to the groove wall of the groove C3 to produce a percussion sound. To this end, during the continuous rotation of the outer ring part 300 relative to the inner ring part 200, the elastic contact 202 can continuously slide into each groove C3 in sequence and slide out of the corresponding groove C3, so that the outer ring part 300 can produce a percussion sound with a rhythmic sense, thereby improving the fun of the user in using the electronic device 000.

[0066] Please note that, please refer to Figure 8 and Fig. 9 The elastic contact 202 may be a part of the inner ring 200, and the elastic contact 202 may be an arched structure protruding from the inner ring 200 toward the outer ring 300. For example, when the inner ring 200 is made of plastic, the elastic contact 202 may be integrally formed with the inner ring 200 by an injection molding process, and when the inner ring 200 is made of metal, the elastic contact 202 may be integrally formed with the inner ring 200 by a stamping process. The present application embodiment does not limit this.

[0067] Please continue to refer to Figure 8 and Fig. 9 In order to improve the deformation capability of the arched structure of the elastic contact 202, the inner ring portion 200 of the electronic device 000 may also have a through groove C5 disposed adjacent to the arched structure, and the through groove C5 may extend along the length direction of the arched structure. Here, the through groove C5 may be distributed on both sides of the arched structure, or only on one side of the arched structure. It should be noted that Figure 8 and Fig. 9 The through groove C5 is distributed on one side of the arch structure as an example for schematic illustration. In this way, when the outer ring portion 300 is subjected to a pulling force in a direction away from the inner ring portion 200, the through groove C5 arranged adjacent to the arch structure can be more conducive to the arch structure to deform under the action of the pulling force, so that the outer ring portion 300 moves in a direction away from the inner ring portion 200, so that the first clamping member 201 of the inner ring portion 200 and the second clamping member 301 of the outer ring portion 300 are clamped.

[0068] Please refer to Figure 8 and Fig. 9The inner ring part 200 in the electronic device 000 may include: a connecting strip 203 distributed on one side of the through groove C5, and an inner ring part body 204 fixedly connected to the connecting strip 203, and the inner ring part body 204 and the connecting strip 203 are used to enclose the through groove C5.

[0069] The portion of the inner ring 200 that is bent toward one side of the outer ring 300 may be an arched structure. After the outer ring 300 is subjected to an externally applied rotational driving force, during the process of the outer ring 300 rotating around the inner ring 200, when the arched structure of the elastic contact 202 does not interfere with the groove C3 of the outer ring 300, the portion of the connecting strip 203 other than the arched structure can be bent and deformed in a direction away from the outer ring 300 and store a rebound force. When the arched structure of the elastic contact 202 slides into the groove C3 of the outer ring 300, the elastic contact 202 will apply a force to the groove wall of the groove C3 to generate a knocking sound.

[0070] In the examples of this application, please refer to Fig.10 and Fig.11 , one of the first clamping member 201 of the inner ring portion 200 and the second clamping member 301 of the outer ring portion 300 may include a plurality of clamping hooks G1. Figure 8 and Fig. 9 The other of the first clamping member 201 of the inner ring portion 200 and the second clamping member 301 of the outer ring portion 300 may include a plurality of clamping grooves C4; and the plurality of clamping hooks G1 correspond one to one with the plurality of clamping grooves C4.

[0071] It should be noted that the drawings in the present application are schematically illustrated by taking the first clamping member 201 provided on the side of the inner ring 200 facing the outer ring 300 as an example, including the clamping groove C4, and the second clamping member 301 provided on the side of the outer ring 300 facing the inner ring 200 as an example, including the clamping hook G1. In other embodiments, the first clamping member 201 of the inner ring 200 may also include the clamping hook G1, and the second clamping member 301 of the outer ring 300 may also include the clamping groove C4. The embodiments of the present application are not limited to this.

[0072] It should be noted that after the outer ring 300 of the electronic device 000 is subjected to an external pulling force in a direction away from the inner ring 200, so that the outer ring 300 can move away from the inner ring 200 as a whole in a direction parallel to the axis of the outer ring 300, the engaging hook G1 may not be exactly located in the engaging groove C4, that is, the first engaging member 201 may not be engaged with the second engaging member 301. To this end, the user not only needs to apply the pulling force to the outer ring 300, but also needs to apply a rotational driving force to the outer ring 300 simultaneously. After the outer ring 300 is subjected to the rotational driving force, the outer ring 300 can rotate relative to the inner ring 200. During this process, the outer ring 300 will continue to be subjected to the pulling force. Therefore, after each engaging hook G1 in the first engaging member 201 is aligned with the engaging groove C4 in the second engaging member 301, at least part of the engaging hook G1 can be engaged with the groove wall in the engaging groove C4. In this case, if the outer ring portion 300 is continuously subjected to a rotational driving force, the outer ring portion 300 and the inner ring portion 200 can rotate synchronously through the engagement between the first engaging member 201 and the second engaging member 301 .

[0073] In the examples of this application, please refer to Figure 7 In a direction perpendicular to the axis of the inner ring portion 200 , the inner ring portion 200 in the electronic device 000 may have a first annular protrusion T1 on one side facing the outer ring portion 300 in the electronic device 000 , and the outer ring portion 300 in the electronic device 000 may have a second annular protrusion T2 on one side facing the inner ring portion 200 in the electronic device 000 .

[0074] In the direction parallel to the axis of the inner ring portion 200 in the electronic device 000 , the second annular protrusion T2 of the outer ring portion 300 may be closer to the device body 100 than the first annular protrusion T1 of the inner ring portion 200 .

[0075] In this case, the first annular protrusion T1 and the second annular protrusion T2 are clamped together to ensure that the outer ring portion 300 sleeved on the inner ring portion 200 will not fall off the inner ring portion 200, so that the outer ring portion 300 can be more stably connected to the inner ring portion 200 for rotation.

[0076] It should be noted that, when the outer ring part 300 in the electronic device 000 is not subjected to an external pulling force, the distance between the second annular protrusion T2 in the outer ring part 300 and the first annular protrusion T1 in the inner ring part 200 can be greater than or equal to the distance between the first clamping member 201 and the second clamping member 301. In this way, it can be ensured that when the outer ring part 300 is subjected to a pulling force in a direction away from the inner ring part 200, so that the first clamping member 201 of the inner ring part 200 and the second clamping member 301 of the outer ring part 300 are clamped, the second annular protrusion T2 of the outer ring part 300 has not yet contacted with the first annular protrusion T1 of the inner ring part 200, so as to ensure that the first clamping member 201 of the inner ring part 200 and the second clamping member 301 of the outer ring part 300 can be reliably clamped.

[0077] In the examples of this application, refer to Figure 6 and Figure 7 , the inner ring part 200 in the electronic device 000 can be threadedly connected with the device body 100 in the electronic device 000. For example, the edge portion of the device body 100 can have an external thread, and the side of the inner ring part 200 facing the device body 100 can have an internal thread, and the inner ring part 200 can be threadedly connected to the edge portion of the device body 100 and apply a certain pre-tightening force. When the outer ring part 300 is not subjected to an external pulling force in a direction away from the inner ring part 200, the first clamping part 201 of the inner ring part 200 and the second clamping part 301 of the outer ring part 300 are separated. After the outer ring part 300 is subjected to a rotational driving force applied from the outside, the outer ring part 300 can rotate freely around the inner ring part 200, thereby improving the fun of the electronic device.

[0078] When the outer ring portion 300 is subjected to an external pulling force in a direction away from the inner ring portion 200, the outer ring portion 300 moves in a direction away from the inner ring portion 200, driving the fixing protrusion 402 of the elastic limit ring 400 located in the first annular groove C1 of the outer ring portion 300 to undergo torsional deformation and store torsional restoring force. The first clamping part 201 of the inner ring portion 200 and the second clamping part 301 of the outer ring portion 300 are clamped. After the outer ring portion 300 is subjected to an external rotational driving force, the outer ring portion 300 can rotate together with the inner ring portion 200, thereby installing the outer ring portion 300 and the inner ring portion 200 on the equipment body 100, or removing the outer ring portion 300 and the inner ring portion 200 from the equipment body 100. When the external pulling force on the outer ring portion 300 in the direction away from the inner ring portion 200 is released, the elastic limit ring 400 will apply a force to the first annular groove C1 of the outer ring portion 300 to move the outer ring portion 300 in the direction toward the inner ring portion 200, thereby making the first clamping part 201 of the inner ring portion 200 and the second clamping part 301 of the outer ring portion 300 no longer engaged.

[0079] It should be noted that different types of outer rings 300 and inner rings 200 can be replaced on the electronic device 000, and the outer ring 300 can cover the inner ring 200, thereby further enriching the decorative effect of the outer ring 300 on the electronic device 000. Here, different types of outer rings 300 can have different appearance colors.

[0080] In summary, an embodiment of the present application provides an electronic device, which may include: a device body, an inner ring, an outer ring, and an elastic limit ring. When the outer ring in the electronic device is not subjected to a pulling force in the direction away from the inner ring, the first clamping part of the inner ring and the second clamping part of the outer ring are separated in a direction parallel to the axis of the inner ring. Therefore, the outer ring sleeved on the inner ring can rotate relative to the inner ring after being subjected to an externally applied rotational driving force. That is, after the outer ring and the inner ring are installed on the device body, the outer ring can rotate relative to the device body after being subjected to an externally applied rotational driving force, thereby enriching the functions of the electronic device. In the case where the outer ring portion in the electronic device is subjected to a pulling force in the direction away from the inner ring portion, after the outer ring portion is subjected to an externally applied rotational driving force, the outer ring portion can rotate together with the inner ring portion, so that during the process of rotating the outer ring portion and the inner ring portion together, the inner ring portion can be screwed into the edge portion of the device body, or can be screwed out from the edge portion of the device body, thereby realizing the installation of the outer ring portion and the inner ring portion on the device body, or the removal of the outer ring portion and the inner ring portion from the device body. The electronic device provided by the present application can not only facilitate users to install the outer ring portion and the inner ring portion on the device body, or remove the outer ring portion and the inner ring portion from the device body, but also allow users to freely rotate the outer ring portion, thereby enriching the functions of the electronic device.

[0081] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.

[0082] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
