To achieve the foregoing objective, the following technical solutions are used in the embodiments of this application:
This application provides an electronic device. The electronic device includes a rear cover, a mounting member, a camera assembly, and a decorative ring. The rear cover is provided with a mounting hole. The mounting member is fixed to an inner wall of the rear cover, a part of the mounting member protrudes from the mounting hole, and the part of the mounting member that protrudes from the mounting hole is provided with a fixing hole. The camera assembly includes a lens, where the lens is fixed to the fixing hole. The decorative ring is fixed to the part of the mounting member that protrudes from the mounting hole, where the decorative ring abuts against an inner wall of the mounting hole, a surface of the decorative ring away from the mounting member is a first surface, the first surface is an inclined surface, a vertical distance between an inner ring edge of the first surface and the rear cover is a first distance, a vertical distance between an outer ring edge of the first surface and the rear cover is a second distance, and the first distance is greater than the second distance.

In the electronic device provided in this application, the decorative ring is arranged between the rear cover and the part of the mounting member that protrudes from the mounting hole, the first surface of the decorative ring is arranged to be an inclined surface, and the first distance is greater than the second distance, so that a crater structure can be formed, that is, a part of the camera assembly that protrudes from the rear cover forms a gradually diffuse structure. In this way, the protruding part of the camera assembly, the rear cover of a mobile phone, and the decorative ring form an appearance integration, thereby being conducive to improving an overall aesthetic. In addition, because the first surface of the decorative ring is the inclined surface, an inclined surface for transition is formed between the protruding part of the camera assembly and an outer wall of the rear cover. When a user holds the electronic device, the decorative ring can support a palm of the user, so the user does not feel uncomfortable due to the protruding part of the camera assembly, thereby being conducive to improving user experience.

In some embodiments of this application, the electronic device further includes a connecting member. The connecting member is arranged between the inner wall of the mounting hole and an outer wall of the decorative ring, the connecting member is connected to the mounting member, and the connecting member abuts against the rear cover and the decorative ring. By fixedly connecting the connecting member and the mounting member, connection strength of an overall structure can be improved, thereby being conducive to improving overall connection stability.

In some embodiments of this application, the connecting member includes a connecting body and a snap hook. The connecting body is arranged between the inner wall of the mounting hole and the outer wall of the decorative ring. The snap hook is connected to the connecting body to be an integral structure. A snap groove is arranged on the mounting member, and the snap hook is in a snap connection to the snap groove. In this way, through the snap connection of the snap hook and the snap groove, on one hand, the connection strength of the overall structure can be improved; and on the other hand, difficulties of mounting and disassembly can be reduced, thereby facilitating disassembly and maintenance of the electronic device.

In some embodiments of this application, a surface of the connecting body away from the snap hook is a second surface, the second surface is an inclined surface, and an inclination angle of the second surface is the same as an inclination angle of the first surface. The second surface of the connecting body is arranged to be an inclined surface and the inclination angle of the second surface is arranged to be the same as the inclination angle of the first surface. In this way, the protruding part of the camera assembly and the rear cover can further form an integral structure, that is, a smooth transition between the protruding part of the camera assembly and the rear cover, to improve an overall structure aesthetic.

In some embodiments of this application, the mounting member includes a first portion and a second portion. The first portion is fixedly connected to the inner wall of the rear cover. The second portion is connected to the first portion to be an integral structure, where the second portion protrudes from the mounting hole, and the second portion is provided with the fixing hole. The second portion protrudes from the mounting hole of the rear cover. In this way, the camera assembly can be mounted at the fixing hole of the second portion, so that a decorative board is fixed to the second portion, and a gradual transition structure between a camera protruding part and the rear cover can be implemented.

In some embodiments of this application, a step surface is formed at a junction of the first portion and the second portion, the step surface faces a direction away from the fixing hole, and the snap groove is arranged on the step surface. In this way, a snap connection between the connecting member and the mounting member can be implemented by snapping the snap hook into the snap groove.

In some embodiments of this application, a first guide inclined surface is arranged on a surface of the snap hook that faces the first portion, and the first guide inclined surface is configured to guide the snap hook to snap into the snap groove. During mounting, the first guide inclined surface enables the formation of separation along a direction parallel to an inclined surface, so that the snap hook slides along the first guide inclined surface, to allow the snap hook to snap into the snap groove.

In some embodiments of this application, a second guide inclined surface is arranged on an edge of the step surface away from the first portion, and an inclination angle of the second guide inclined surface is the same as an inclination angle of the first guide inclined surface. In this way, during mounting, when the snap hook abuts against the second portion, the first guide inclined surface and the second guide inclined surface abut against each other and slide relatively, to further reduce the difficulty of mounting.

In some embodiments of this application, an edge of the mounting hole forms an abutting portion bent in a direction facing the mounting member, and a surface of the connecting body that faces the mounting member abuts against a surface of the abutting portion away from the mounting member. In this way, the edge of the mounting hole of the rear cover can abut between the connecting body and the mounting member, thereby further improving connection strength among the rear cover, the camera assembly, and the mounting member. In addition, it is conducive to protecting the edge of the mounting hole of the rear cover and preventing a material on the edge of the mounting hole from falling off.

In some embodiments of this application, the rear cover includes a rear cover body and a decorative layer. The decorative layer is fixed to a surface of the rear cover body away from the mounting member, where the abutting portion is formed on the decorative layer. Through the decorative layer, an overall appearance of the electronic device can be further improved, and a feeling of holding the electronic device of the user can be improved.

In some embodiments of this application, the decorative layer is made of a polyurethane material. In some embodiments of this application, the rear cover body is made of a glass fiber material or a polycarbonate material.

In some embodiments of this application, a boss is formed on an inner wall of the fixing hole, and the lens is fixed to a surface of the boss that faces the outside of the electronic device. In this way, a surface of the lens can be attached and fixed to the boss, thereby reducing the difficulty of mounting and improving fixing strength of the lens.

In some embodiments of this application, the boss extends circumferentially around the fixing hole through one circle. In this way, the boss forms an annular structure around the fixing hole through one circle, to increase an attachment area between the boss and the lens, further improve the fixing strength of the lens, and improve supporting strength of the boss.

In some embodiments of this application, a plurality of bosses are arranged, and the plurality of bosses are evenly distributed circumferentially around the fixing hole. The plurality of bosses are evenly distributed. On one hand, the lens can be supported. On the other hand, materials can be reduced, thereby being conducive to reducing costs.

The housing is configured to protect components inside the electronic device <NUM>, and can make an appearance of the electronic device <NUM> more aesthetic. In addition, the rear cover <NUM> is provided with a mounting hole <NUM> to expose the camera assembly <NUM>.

<FIG> is a cross-sectional view of a partial structure of an electronic device provided in the prior art. With reference to <FIG>, the foregoing camera assembly <NUM> includes a camera body (not shown in the figure), a mounting member <NUM>, and a lens <NUM>, and the camera body is arranged inside the housing of the electronic device <NUM>. The mounting member <NUM> is mounted at the mounting hole <NUM> on the rear cover <NUM>, and a part of the mounting member protrudes from the rear cover <NUM>. The lens <NUM> is mounted at a fixing hole <NUM> on the part of the mounting member <NUM> that protrudes from the rear cover <NUM>.

To improve a photographing effect, in the prior art, a quantity of camera bodies arranged inside the electronic device <NUM> continuously increases. As a result, an overall structure of the camera assembly <NUM> is continuously enlarged. Therefore, the camera assembly <NUM> protrudes from the rear cover <NUM>, an overall structure of the electronic device <NUM> is not aesthetic enough due to the protruding part, and a sense of comfort of a user when holding the electronic device <NUM> is affected. To resolve the foregoing problem, as shown in <FIG>, in the prior art, an edge of the mounting hole <NUM> of the rear cover <NUM> is inclined and extended to form a connecting portion <NUM>. As shown in <FIG>, the connecting portion <NUM> extends in a direction close to the camera assembly <NUM>, and forms a transition structure, namely, a gradually extending crater structure, between the part of the camera assembly <NUM> that protrudes from the rear cover <NUM> and the rear cover <NUM>, so that the rear cover <NUM> and the camera assembly <NUM> of the electronic device <NUM> can form an appearance integration, thereby being conducive to an overall aesthetic of the electronic device <NUM>. In addition, when the user holds the electronic device <NUM>, the connecting portion <NUM> can support a palm or fingers of the user, thereby improving the sense of comfort of the user when holding the electronic device <NUM>.

However, when manufacturing the rear cover <NUM> in the foregoing technical solutions, a specified process step is required for forming the foregoing connecting portion <NUM>. Therefore, a production difficulty and production costs increase.

In this application, to resolve the foregoing problem, as shown in <FIG> is a diagram of a structure of an electronic device <NUM> according to an embodiment of this application, and <FIG> is a cross-sectional view of a structure of an electronic device according to an embodiment of this application. The electronic device <NUM> includes a rear cover <NUM>, a mounting member <NUM>, a decorative ring <NUM>, a connecting member <NUM>, and a camera assembly <NUM> (only a lens <NUM> of the camera assembly <NUM> is shown in <FIG>).

Specifically, as shown in <FIG>, the foregoing rear cover <NUM> is provided with a mounting hole <NUM>. As shown in <FIG>, the mounting member <NUM> includes a first portion <NUM> and a second portion <NUM>. The first portion <NUM> is fixed to the inside of the rear cover <NUM>. The second portion <NUM> protrudes from the mounting hole <NUM> of the rear cover <NUM>, and the second portion <NUM> is provided with a fixing hole <NUM>. The lens <NUM> of the camera assembly <NUM> is fixed to the fixing hole <NUM>.

In addition, as shown in <FIG>, the electronic device <NUM> provided in this application further includes a decorative ring <NUM>. The decorative ring <NUM> is attached and fixed to the second portion <NUM>, and is arranged to extend around the fixing hole <NUM> of the second portion <NUM> through one circle. A surface of the decorative ring <NUM> away from the mounting member <NUM> is a first surface <NUM>, and the first surface <NUM> is an inclined surface. A vertical distance between an inner ring edge of the first surface <NUM> and the rear cover <NUM> is a first distance, a vertical distance between an outer ring edge of the first surface <NUM> and the rear cover <NUM> is a second distance, and the first distance is greater than the second distance.

In this way, by arranging the decorative ring <NUM> between the rear cover <NUM> and the second portion <NUM> of the mounting member <NUM>, the overall aesthetic of the electronic device <NUM> is improved. The first surface <NUM> of the decorative ring <NUM> is arranged to be an inclined surface, and the first distance is greater than the second distance, so that the decorative ring <NUM> forms a crater structure between the mounting hole <NUM> of the rear cover <NUM> and the second portion <NUM> of the mounting member <NUM>. That is, a gradually extending structure is formed between a part of the second portion <NUM> that protrudes from the rear cover <NUM> and the rear cover <NUM>, so that the second portion <NUM>, the rear cover <NUM>, and the decorative ring <NUM> form an appearance integration, thereby being conducive to improving the overall aesthetic.

In addition, by arranging the first surface <NUM> of the decorative ring <NUM> to be an inclined surface, an inclined surface for transition is formed between the second portion <NUM> of the mounting member <NUM> and the rear cover <NUM>. When a user holds the electronic device <NUM>, the decorative ring <NUM> can support a palm of the user, to increase a contact area between the electronic device <NUM> and the palm of the user, so that the user does not feel uncomfortable due to the protruding part on the rear cover <NUM>, thereby being conducive to improving a sense of comfort of the user when holding the electronic device <NUM>, and improving user experience.

It is to be noted that, the first portion <NUM> of the mounting member <NUM> and the rear cover <NUM>, as well as the second portion <NUM> of the mounting member <NUM> and the decorative ring <NUM>, may be fixedly connected by using an adhesive, for example, a back adhesive. Another fixing manner may also be used, and this application sets no special limitation thereto.

As shown in <FIG>, an overall thickness of the foregoing decorative ring <NUM> may be exactly the same, that is, the decorative ring <NUM> is made by using materials with the same thickness, and a cross-section of the decorative ring is of an approximately rectangular structure. In this case, a region where the second portion <NUM> of the mounting member <NUM> is attached and fixed to the decorative ring <NUM> may just be arranged to be an inclined surface whose inclination angle is the same an inclination angle of the first surface <NUM>. In this way, it is conducive to reducing a processing difficulty of the decorative ring <NUM> to further reduce production costs.

In another embodiment, as shown in <FIG>, the overall thickness of the decorative ring <NUM> may also not be exactly the same. For example, the first surface <NUM> of the decorative ring <NUM> is arranged to be an inclined surface, and a surface opposite to the first surface <NUM> is arranged to be a planar surface, that is, the cross-section of the decorative ring <NUM> is of an approximately right-angle trapezoidal structure. In this case, the region where the second portion <NUM> of the mounting member <NUM> is attached and fixed to the decorative ring <NUM> is arranged to be a planar surface, so that a fixed connection between the decorative ring <NUM> and the second portion <NUM> can be implemented.

In addition, to further improve the overall aesthetic of the electronic device <NUM>, as shown in <FIG>, the rear cover <NUM> provided in this application may include a rear cover body <NUM> and a decorative layer <NUM>. The decorative layer <NUM> is attached and fixed to a surface of the rear cover body <NUM> away from the mounting member <NUM>. The overall aesthetic of the back of the electronic device <NUM> can be improved through the decorative layer <NUM>.

Exemplarily, the foregoing decorative layer <NUM> may be made of a PU (polyurethane, polyurethane) material. The rear cover body <NUM> is covered by using the PU material, so that the overall rear cover <NUM> is more aesthetic. In addition, elastic performance of the PU material is between plastic and rubber. Therefore, when the user holds the electronic device <NUM>, a touch feeling of the rear cover <NUM> made of the PU material is better, and the user experience can be improved.

In some embodiments, the foregoing rear cover body <NUM> may be made of a glass fiber material or a PC (Polycarbonate, polycarbonate) material, thereby forming a support.

It is to be noted that, both the foregoing decorative layer <NUM> and the rear cover body <NUM> are not limited to the foregoing materials, which may be replaced with other materials. Therefore, this application sets no special limitation thereto.

Based on this, as shown in <FIG>, the foregoing connecting member <NUM> provided in this embodiment of this application is arranged between an inner wall of the mounting hole <NUM> and an outer wall of the decorative ring <NUM>, the connecting member <NUM> is connected to the mounting member <NUM>, and the connecting member <NUM> abuts against both the rear cover <NUM> and the decorative ring <NUM>. In this way, the connecting member <NUM> is arranged between the mounting hole <NUM> of the rear cover <NUM> and the decorative ring <NUM>, and the connecting member <NUM> is connected to the mounting member <NUM>, so that overall connection strength can be improved, and a transition between the rear cover <NUM> and the decorative ring <NUM> is smoother, thereby being conducive to further improving the overall aesthetic.

In some embodiments, the connecting member <NUM>, the decorative ring <NUM>, and the mounting member <NUM> may each be of a different color, so that an appearance of the electronic device <NUM> is more colorful, and the overall aesthetic can be further improved.

Specifically, the foregoing connecting member <NUM> includes a connecting body <NUM> and a snap hook <NUM>. The connecting body <NUM> is arranged between the inner wall of the mounting hole <NUM> and the outer wall of the decorative ring <NUM>. The snap hook <NUM> is connected to the connecting body <NUM> to be an integral structure. A snap groove <NUM> is arranged on the second portion <NUM> of the mounting member <NUM>, and the snap hook <NUM> is in a snap connection to the snap groove <NUM>. Therefore, a snap connection of the connecting member <NUM> and the mounting member <NUM> can be implemented. On one hand, the snap connection of the connecting member <NUM> and the mounting member <NUM> can be implemented, to improve connection strength of an overall structure. On the other hand, difficulties of mounting and disassembly can be reduced, thereby facilitating disassembly and maintenance of the electronic device <NUM>.

In some embodiments, as shown in <FIG> and <FIG>, a step surface <NUM> may be formed between the first portion <NUM> of the mounting member <NUM> and the second portion <NUM> of the mounting member <NUM>. That is, at a junction of the second portion <NUM> and the first portion <NUM>, the second portion <NUM> is higher than the first portion <NUM> to form the step surface <NUM>, that is, the step surface <NUM> faces a direction away from the fixing hole <NUM>. In addition, the foregoing snap groove <NUM> is arranged on the step surface <NUM>, thereby allowing the snap hook <NUM> to snap into the snap groove <NUM>.

To allow the foregoing snap hook <NUM> to snap into the snap groove <NUM>, thereby reducing the difficulty of mounting, as shown in <FIG>, a first guide inclined surface <NUM> is arranged on a surface of the snap hook <NUM> that faces the first portion <NUM>, a second guide inclined surface <NUM> is arranged on an edge of the step surface <NUM> away from the first portion <NUM>, and an inclination angle of the first guide inclined surface <NUM> is the same as an inclination angle of the second guide inclined surface <NUM>. In this way, when mounting the connecting member <NUM>, when the snap hook <NUM> abuts against the second portion <NUM>, that is, the first guide inclined surface <NUM> and the second guide inclined surface <NUM> abut against each other, because the first guide inclined surface and the second guide inclined surface are inclined surfaces, a force parallel to the inclined surfaces can be generated between the first guide inclined surface and the second guide inclined surface, so that the snap hook <NUM> and the second portion <NUM> can relatively slide along the inclined surfaces, to allow the snap hook <NUM> to snap into the snap groove <NUM>, thereby being conducive to reducing the difficulty of mounting.

In addition, as shown in <FIG>, a surface of the connecting body <NUM> away from the snap hook <NUM> is a second surface <NUM>, the second surface <NUM> is an inclined surface, and an inclination angle of the second surface <NUM> is the same as an inclination angle of the first surface <NUM>. In this way, the transition between the decorative ring <NUM> and the rear cover <NUM> can be smoother, thereby being more conducive to implementation of appearance integration of the decorative ring <NUM> and the rear cover <NUM>, and further improving an overall appearance effect.

To further improve the connection strength of the overall structure, as shown in <FIG>, an edge of the mounting hole <NUM> of the rear cover <NUM> forms an abutting portion <NUM> bent in a direction close to the mounting member <NUM>, and a surface of the connecting body <NUM> that faces the mounting member <NUM> abuts against a surface of the abutting portion <NUM> away from the mounting member <NUM>. The edge of the mounting hole <NUM> of the rear cover <NUM> abuts between the connecting body <NUM> and the mounting member <NUM>. In this way, the connection strength between the rear cover <NUM> and the mounting member <NUM> can be further improved.

In addition, the edge of the mounting hole <NUM> can be hidden by the connecting body <NUM>, thereby preventing a material on the edge of the mounting hole <NUM> from falling off. For example, at the edge of the mounting hole <NUM>, the foregoing decorative layer <NUM> separates from the rear cover body <NUM>, resulting in damage to the rear cover <NUM>. Therefore, the edge of the mounting hole <NUM> can be protected, to prolong a use life of the rear cover <NUM>.

Exemplarily, the foregoing abutting portion <NUM> may be formed on an edge of the decorative layer <NUM>. In addition, an inclined surface inclined to the direction close to the mounting member <NUM> is formed on the rear cover body <NUM>, which enables the abutting portion <NUM> to be attached to the inclined surface, so that the abutting portion <NUM> can abut against the surface of the connecting body <NUM> that faces the mounting member <NUM>.

Based on this, as shown in <FIG>, the foregoing lens <NUM> is fixed to the fixing hole <NUM> on the second portion <NUM> of the mounting member <NUM>, to prevent the lens <NUM> from moving along a direction perpendicular to an axis of the fixing hole <NUM>. The lens <NUM> may abut against an inner wall of the fixing hole <NUM>, so that the lens <NUM> can be limited from moving along the direction perpendicular to the axis of the fixing hole <NUM>, and a limit is formed to the lens <NUM> to prevent the lens <NUM> from moving, which helps to ensure a photographing effect.

A side wall of the lens <NUM> and the inner wall of the fixing hole <NUM> may be fixedly connected by using an adhesive. As shown in <FIG>, a boss <NUM> may also be formed on the inner wall of the fixing hole <NUM>, and the lens <NUM> is fixed to a surface of the boss <NUM> that faces the outside of the rear cover <NUM>. The lens <NUM> can be supported by the boss <NUM>, thereby improving support strength of the overall structure. In addition, the lens <NUM> is fixedly connected to the boss <NUM>, thereby implementing a fixed connection of the lens <NUM> and the mounting member <NUM>.

In addition, the boss <NUM> may extend circumferentially around the fixing hole <NUM> through one circle, so that an attachment area between the boss <NUM> and the lens <NUM> can be increased, to improve fixing strength between the lens <NUM> and the mounting member <NUM>. Exemplarily, the lens <NUM> may be fixed to the boss <NUM> by using a back adhesive, thereby implementing the fixed connection by using the adhesive.

In another embodiment, as shown in <FIG>, a plurality of bosses <NUM> may also be arranged, and the plurality of bosses <NUM> are evenly distributed circumferentially around the fixing hole <NUM>, thereby forming a balanced support and even force. Therefore, an arrangement manner of the boss is not specifically limited in this application.

It is to be noted that, the foregoing lens <NUM> may be bonded and fixed to the boss <NUM> by using the adhesive, for example, by using the back adhesive to bond and fix the lens to the boss. Another adhesive material may also be used to perform gluing fixation. This application sets no special limitation thereto.

In the descriptions of this specification, the specific features, structures, materials, or characteristics may be combined in a proper manner in any one or more of the embodiments or examples.
