DETAILED DESCRIPTION

[0009] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0010] The terms "first," "second," etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequential sequence. It should be understood that the numerals used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and that the objects distinguished by "first," "second," etc. are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0011] The technical solutions disclosed in various embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0012] In related art, for example, a mobile phone or tablet with a camera function is equipped with a rear camera. To protect the rear camera, a decorative ring is placed on the housing (back cover) of the phone or tablet. The decorative ring has a light-transmitting area that is positioned opposite the rear camera. Currently, the decorative ring is typically secured to the back cover by bonding. However, due to limitations such as the durability and bonding area of ​​the adhesive material, such as the gradual decrease in the adhesive's viscosity and the insufficient bonding area between the decorative ring and the back cover, this can lead to poor assembly reliability between the decorative ring and the back cover, which can easily cause the decorative ring to fall off the housing.

[0013] Based on the above questions, please refer to Figures 1 to 14 The embodiment of the present application discloses an electronic device, which may be a mobile phone, a tablet computer, a laptop computer, a wearable device, a vehicle-mounted device, etc. The embodiment of the present application does not limit the specific type of the electronic device.

[0014] The above-mentioned electronic device may include a decorative ring assembly 100 and a housing 200. The housing 200 is the structural basis of the electronic device. Housings 200 of different structures include different components. For example, the housing 200 may include a front shell, a back cover, and a middle frame disposed therebetween. For another example, the housing 200 may include a front cover and a back cover, with a frame formed on the front cover or the back cover, and the frame is located between the front cover and the back cover. The back cover here may be a battery cover. The housing 200 has an inner cavity, which is used to install components such as a camera module and a circuit board of the electronic device. The housing 200 is provided with a through hole 210 connected to the inner cavity, and the through hole 210 is disposed opposite to the camera module of the electronic device.

[0015] The decorative ring assembly 100 described above may include a decorative ring body 110, a mating piece 120, and a connecting piece 130. The decorative ring body 110 is disposed outside the housing 200 and covers the through-hole 210 on the housing 200. The decorative ring body 110 is primarily used to protect the camera module of the electronic device. The decorative ring body 110 may specifically include a decorative frame and a light-transmitting cover disposed above the decorative frame. The decorative frame may be disposed around the through-hole 210 of the housing 200, and the light-transmitting cover may be disposed opposite the camera module. The mating piece 120 is disposed within the housing 200. It should be noted that the housing 200 may have an inner surface and an outer surface, wherein the inner surface is the surface of the housing 200 facing the inner cavity, and the outer surface is the surface of the housing 200 facing away from the inner cavity. The decorative ring body 110 may overlap the outer surface of the housing 200, and the mating piece 120 may overlap the inner surface of the housing 200.

[0016] The connector 130 is used to connect the decorative ring body 110 and the mating member 120. Specifically, the connector 130 has a first end and a second end facing each other. The first end of the connector 130 can be connected to one of the decorative ring body 110 and the mating member 120. The specific connection method may be bonding, clamping, or bolting. The first direction and the second direction are defined as two opposite directions. With reference to the circular through-hole 210, the first direction can be from the center to the edge of the through-hole 210, and the second direction can be from the edge to the center of the through-hole 210. A first stopper 140 extending in the first direction is provided at the second end of the connector 130. A second stopper 150 extending in the second direction is provided on the other of the decorative ring body 110 and the mating member 120. The first stopper 140 can pass through the through-hole 210 of the housing 200 and engage with the second stopper 150, thereby clamping the decorative ring body 110 and the mating member 120 to the housing 200. The cooperation relationship between the first limiting portion 140 and the second limiting portion 150 can be elastic snap connection, magnetic snap connection, rotational snap connection, etc. As long as the decorative ring body 110 and the mating part 120 can be limited respectively through the snap connection between the first limiting portion 140 and the second limiting portion 150, the embodiment of the present application does not limit the cooperation relationship between the first limiting portion 140 and the second limiting portion 150.

[0017] For example, the first end of the connector 130 can be connected to the decorative ring body 110, the second end of the connector 130 is provided with a first stopper 140 extending in the first direction, and the mating member 120 is provided with a second stopper 150 extending in the second direction. Alternatively, the first end of the connector 130 can be connected to the mating member 120, the second end of the connector 130 is provided with a first stopper 140 extending in the first direction, and the decorative ring body 110 is provided with a second stopper 150 extending in the second direction. Under the snap-fit ​​engagement between the first stopper 140 and the second stopper 150, the connector 130 can apply a force to the decorative ring body 110 and the mating member 120, forcing the two to approach each other, thereby pressing the decorative ring body 110 against the outer surface of the housing 200 and the mating member 120 against the inner surface of the housing 200, ultimately achieving the decorative ring body 110 and the mating member 120 clamping the housing 200.

[0018] From the above description, it can be seen that the electronic device disclosed in the embodiment of the present application improves the relevant technology, and utilizes the snap-fit ​​cooperation between the first limiting portion 140 and the second limiting portion 150 to enable the decorative ring body 110 and the mating part 120 to clamp the shell 200, thereby improving the assembly reliability between the decorative ring assembly 100 and the shell 200, thereby reducing the probability of the decorative ring body 110 falling off from the shell 200, and improving the durability of the electronic device.

[0019] In an optional embodiment of the present application, to improve the assembly efficiency between the decorative ring body 110, the connector 130, and the mating member 120, the first end of the connector 130 can be fixedly connected to the decorative ring body 110. The specific connection method can be bonding, bolting, etc. To ensure the structural strength of the connector 130 and the decorative ring body 110, the connector 130 and the decorative ring body 110 can also be an integrated structure, specifically, they can be manufactured by injection molding. In this embodiment, the second end of the connector 130 is provided with a first limiting portion 140 extending along the first direction, and the mating member 120 is provided with a second limiting portion 150 extending along the second direction.

[0020] Since the first end of the connecting member 130 is fixedly connected to the decorative ring body 110, during actual assembly, it is only necessary to snap the first limiting portion 140 and the second limiting portion 150 together to achieve rapid assembly of the decorative ring body 110, the connecting member 130 and the mating member 120, thereby simplifying the assembly steps and improving assembly efficiency.

[0021] like Figures 1 to 4 As shown, in the embodiment where the first end of the connector 130 is fixedly connected to the decorative ring body 110, the connector 130 may specifically include a base 131, a first elastic arm 132, and a second elastic arm 133. The base 131, the first elastic arm 132, and the second elastic arm 133 may be made of elastic plastic. The base 131 may be fixedly connected to the decorative ring body 110, and the first elastic arm 132 and the second elastic arm 133 are respectively connected to the ends of the base 131 and extend in a direction away from the decorative ring body 110. The base 131, the first elastic arm 132, and the second elastic arm 133 may be a one-piece structure, or they may be manufactured separately and then assembled together by bonding. There is a gap between the first elastic arm 132 and the second elastic arm 133 for the two to approach each other, and the end of the first elastic arm 132 and the end of the second elastic arm 133 are both provided with a first limiting portion 140, wherein the first limiting portion 140 can be a raised buckle, and accordingly, the second limiting portion 150 can also be a raised buckle, and the extension directions of the first limiting portion 140 and the second limiting portion 150 are opposite.

[0022] During the actual assembly process, a force can be applied to the first elastic arm 132 and the second elastic arm 133 passing through the through hole 210 respectively so that the two are elastically deformed and approach each other, and then the first limiting portion 140 and the second limiting portion 150 are moved relative to each other. When the first limiting portion 140 and the second limiting portion 150 move relative to each other to a position where they can be engaged with each other, the force applied to the first elastic arm 132 and the second elastic arm 133 is removed, so that the first elastic arm 132 and the second elastic arm 133 rebound and drive the first limiting portion 140 to press the second limiting portion 150, thereby realizing the engaging fit between the first limiting portion 140 and the second limiting portion 150.

[0023] In conjunction with the above content, please continue to refer to Figures 1 to 4 The mating member 120 may be provided with a first engaging hole 121, and second limiting portions 150 are respectively provided on both sides of the hole wall of the first engaging hole 121. The first elastic arm 132 and the second elastic arm 133 have a first state in which they are close to each other and a second state in which they are separated from each other. When the first elastic arm 132 and the second elastic arm 133 are in the first state, the size of the whole formed by the first elastic arm 132 and the second elastic arm 133 is small, so that the first limiting portion 140 can pass through the first engaging hole 121. When the first limiting portion 140 and the second limiting portion 150 move relative to each other to a position where they can engage with each other, the force applied to the first elastic arm 132 and the second elastic arm 133 can be removed, so that the first elastic arm 132 and the second elastic arm 133 are in the second state. At this time, the first elastic arm 132 and the second elastic arm 133 rebound and drive the first limiting portion 140 to press against the second limiting portion 150, thereby achieving the engaging engagement between the first limiting portion 140 and the second limiting portion 150.

[0024] When assembling the decorative ring body 110, the connecting piece 130 and the matching piece 120, the decorative ring body 110 can be overlapped on the outer surface of the shell 200 first, and then the first clamping hole 121 on the matching piece 120 is aligned with the first elastic arm 132 and the second elastic arm 133. After the alignment is completed, the matching piece 120 can be pressed down to make the second limiting part 150 and the first limiting part 140 slide relative to each other. At this time, the second limiting part 150 can squeeze the first limiting part 140 and drive the first elastic arm 132 and the second elastic arm 133 approach each other, and when the first elastic arm 132 and the second elastic arm 133 are in the first state, the first limiting portion 140 can pass through the first engaging hole 121; when the mating piece 120 contacts the inner surface of the housing 200, the force applied to the mating piece 120 can be removed. At this time, the first elastic arm 132 and the second elastic arm 133 rebound and drive the first limiting portion 140 to press against the second limiting portion 150, thereby achieving the engaging engagement between the first limiting portion 140 and the second limiting portion 150. Of course, the engaging piece 120 can also be overlapped on the inner surface of the housing 200 first, and then the decorative ring body 110 is pressed down, which can also achieve the engaging engagement between the first limiting portion 140 and the second limiting portion 150.

[0025] When the first limiting portion 140 and the second limiting portion 150 slide relative to each other, to enable the second limiting portion 150 to smoothly drive the first elastic arm 132 and the second elastic arm 133 toward each other, a first guide surface 141 can be provided on the side of the first limiting portion 140 away from the base 131, and a second guide surface 151 can be provided on the side of the second limiting portion 150 closer to the base 131. With the plane of the first engaging hole 121 as a reference, the first guide surface 141 and the second guide surface 151 are both arranged at a predetermined angle with respect to the plane of the first engaging hole 121. The predetermined angle can be 30°-60°, specifically 30°, 45°, 60°, etc. When the first limiting portion 140 is inserted into the first engaging hole 121, the first guide surface 141 can slide in conjunction with the second guide surface 151, thereby applying a squeezing force to the first guide surface 141 by the second guide surface 151, driving the first elastic arm 132 and the second elastic arm 133 toward each other.

[0026] In an optional embodiment of the present application, the first limiting portion 140 and the second limiting portion 150 can also be assembled by rotating and snapping. Specifically, as shown in FIG. Figures 5 to 14 As shown, the first end of the connecting member 130 can be connected to one of the decorative ring body 110 and the mating member 120, and the second end of the connecting member 130 is provided with a first stopper 140 extending along the first direction. The other of the decorative ring body 110 and the mating member 120 is provided with a second engaging hole 160, and the hole wall of the second engaging hole 160 is provided with a second stopper 150 extending along the second direction. For example, the first end of the connecting member 130 can be connected to the decorative ring body 110, and the mating member 120 is provided with the second engaging hole 160; alternatively, the first end of the connecting member 130 can be connected to the mating member 120, and the decorative ring body 110 is provided with the second engaging hole 160.

[0027] The connecting member 130 can extend into the second engaging hole 160 and be rotatably connected to the second engaging hole 160. When the connecting member 130 and the second engaging hole 160 are in a first relative position, the first limiting portion 140 and the second limiting portion 150 are offset from each other in the axial direction of the second engaging hole 160, so that the first limiting portion 140 can pass through the second engaging hole 160. When the connecting member 130 and the second engaging hole 160 are relatively rotated to the second relative position, the first limiting portion 140 and the second limiting portion 150 overlap with each other in the axial direction of the second engaging hole 160, so that the first limiting portion 140 can be engaged with the second limiting portion 150. During actual assembly, the connecting member 130 and the second engaging hole 160 can be rotated relative to each other by rotating the connecting member 130, or by rotating the second engaging hole 160, which is not limited in this embodiment of the present application.

[0028] Furthermore, at least two second limiting portions 150 may be provided at intervals along the circumference of the wall of the second engaging hole 160, with mounting notches 161 formed between adjacent second limiting portions 150. Accordingly, at least two first limiting portions 140 are provided at intervals along the second end of the connector 130, with the number of first limiting portions 140 being equal to and corresponding to the number of second limiting portions 150. When the connector 130 and the second engaging hole 160 are in a first relative position, the first limiting portions 140 can pass through the mounting notches 161. When the connector 130 and the second engaging hole 160 are rotated relative to each other to a second relative position, the first limiting portions 140 can engage with the second limiting portions 150. With the above design, on the one hand, when the first limiting portion 140 and the second limiting portion 150 are rotationally engaged, there is no need to distinguish the rotation direction, thereby reducing the difficulty of operation; on the other hand, the corresponding engagement between at least two first limiting portions 140 and at least two second limiting portions 150 can evenly distribute the force, thereby improving the reliability of assembly.

[0029] It should be added that, Figures 7 and 8 As shown, the end surface of the second limiting portion 150 for engaging with the first limiting portion 140 may include a guide section 152, a transition section 153, and a sinking section 154 arranged in sequence along the circumference of the second engaging hole 160. In the direction in which the three sections are arranged, the guide section 152 gradually rises, the transition section 153 approaches a horizontal position, and the sinking section 154 gradually descends to form a slot. When the connector 130 and the second engaging hole 160 switch from a first relative position to a second relative position, the first limiting portion 140 sequentially slides relative to the guide section 152 and the transition section 153, and ultimately engages with the sinking section 154 (slot), thereby reducing the difficulty of rotating the first limiting portion 140 and the second limiting portion 150 and improving the stability of the engagement between the first limiting portion 140 and the second limiting portion 150.

[0030] In an optional embodiment of the present application, the first end of the connector 130 can be fixedly connected to the decorative ring body 110, and the specific connection method can be bonding, bolting, etc. In order to ensure the structural strength of the connector 130 and the decorative ring body 110, the connector 130 and the decorative ring body 110 can also be an integral structure, which can be specifically produced by injection molding. In this embodiment, the second end of the connector 130 is provided with a first limiting portion 140 extending along the first direction, the matching piece 120 is provided with a second snap-fitting hole 160, and the hole wall of the second snap-fitting hole 160 is provided with a second limiting portion 150 extending along the second direction. During actual assembly, the second snap-fitting hole 160 can be driven to rotate by rotating the matching piece 120, so that the connector 130 and the second snap-fitting hole 160 are in the first relative position (such as Figure 5 ) and the second relative position (as shown Figure 6 (as shown).

[0031] Since the first end of the connecting member 130 is fixedly connected to the decorative ring body 110, during actual assembly, it is only necessary to rotate and clamp the first limiting portion 140 and the second limiting portion 150 together to achieve rapid assembly of the decorative ring body 110, the connecting member 130 and the mating member 120, thereby simplifying the assembly steps and improving assembly efficiency.

[0032] It should be added that, considering that the first limiting portion 140 needs to slide relative to the guide section 152 and the transition section 153 in sequence, and finally engage with the sinking section 154, and the position of the transition section 153 is relatively high, in order to enable the first limiting portion 140 to slide smoothly over the transition section 153, the mating piece 120 can be pressed down while rotating the mating piece 120. After the first limiting portion 140 slides to the sinking section 154, the pressure applied to the mating piece 120 is removed, and the mating piece 120 rebounds to enable the first limiting portion 140 to be stably engaged with the sinking section 154.

[0033] In another optional embodiment of the present application, Figures 9 to 14 As shown, the first end of the connecting member 130 can be driven to connect with the matching member 120, and the second end of the connecting member 130 can be rotatably engaged with the decorative ring body 110. The matching member 120 can be used to drive the connecting member 130 to rotate so that the connecting member 130 and the decorative ring body 110 are engaged or separated with each other.

[0034] Specifically, the first end of the connector 130 is provided with a first limiting portion 140 extending in a first direction. The decorative ring body 110 is provided with a second engaging hole 160. The wall of the second engaging hole 160 is provided with a second limiting portion 150 extending in a second direction. The first limiting portion 140 and the second limiting portion 150 can be assembled by rotational engagement. The mating member 120 is provided with a guide hole 122. The wall of the guide hole 122 is provided with a driving protrusion 123. The side of the connector 130 is provided with a sliding groove 1341. The sliding groove 1341 extends in a spiral shape from the first end of the connector 130 to the second end of the connector 130. One end of the sliding groove 1341 is open, and the open end of the sliding groove 1341 is located at the first end of the connector 130. The other end of the sliding groove 1341 is closed.

[0035] During actual assembly, the decorative ring body 110 can be overlapped on the first surface of the shell 200, and then the second end of the connecting member 130 can be extended into the second clamping hole 160. At this time, the first limiting portion 140 passes through the installation notch 161; then the matching member 120 and the connecting member 130 are aligned and installed so that the driving protrusion 123 in the guide hole 122 is docked with the open end of the slide groove 1341, and then the matching member 120 is pressed down so that the decorative ring body 110 and the matching member 120 are close to each other, and the driving protrusion 123 can The drive protrusion 123 enters the slide groove 1341 from the open end of the slide groove 1341. At this time, the driving protrusion 123 can limit each other with the slide groove 1341 in the axial direction of the connecting member 130, and the limited assembly of the connecting member 130 and the matching member 120 can be realized. When the driving protrusion 123 and the slide groove 1341 slide relative to each other, the driving protrusion 123 can drive the connecting member 130 to rotate, so that the connecting member 130 and the second clamping hole 160 are switched from the first relative position to the second relative position, thereby realizing the assembly of the connecting member 130 and the decorative ring body 110.

[0036] It should be noted that when the connecting member 130 and the second snap-fitting hole 160 are in the second relative position, the first limiting portion 140 can be snap-fitted with the sinking section 154. At this time, the decorative ring body 110, the mating member 120 and the connecting member 130 are in a locked state. In other words, the snap-fitting between the first limiting portion 140 and the sinking section 154 can limit the rotation of the connecting member 130, so the slide groove 1341 of the connecting member 130 and the driving protrusion 123 no longer produce relative sliding. Accordingly, by utilizing the mutual limitation of the driving protrusion 123 and the slide groove 1341 in the axial direction of the connecting member 130, the mating member 120 can be pressed against the inner surface of the shell 200, and the decorative ring body 110 can be pressed against the outer surface of the shell 200.

[0037] like Figure 11 As shown, the above-mentioned connecting member 130 may include a first column 134 and a second column 135 connected to each other. The first column 134 and the second column 135 may be an integral structure, or they may be manufactured separately and then assembled by bonding, hot-melt connection, etc. The diameter of the first column 134 is larger than the diameter of the second column 135.
