DETAILED DESCRIPTION

[0059] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be described in further detail below with reference to the drawings.

"Multiple" means two or more, unless otherwise specified.

[0061] As people's requirements for the camera function of the terminal become higher, the number and volume of camera assemblies gradually increase, the volume of camera decoration pieces also gradually increases, and the occupation of the terminal internal space by the camera decoration pieces also gradually increases.

[0062] To reduce the occupation of the terminal internal space by the camera decoration pieces, while taking into account the overall structural strength and IP68 protection requirements, the embodiments of the present application provide a camera decoration piece mounting structure.

[0063] As shown in Figure 1 , Figure 2 and Figure 6 , the camera decoration piece mounting structure includes a terminal housing 1, a camera decoration piece 2, and a sealing piece 3.

[0064] The terminal housing 1 has a mounting hole 10 for mounting the camera decoration piece 2. The material of the terminal housing 1 can be glass, ceramic, plastic, or metal, etc. When the mounting structure provided by the embodiments of the present application is applied in a mobile phone, the terminal housing 1 can be a mobile phone back cover. The shape of the mounting hole 10 matches the camera decoration piece 2, for example, it can be a circular hole or a square hole, etc.

[0065] As shown in Figure 3 and Figure 4As shown, the camera decoration 2 comprises a main body 21 and a sealing part 22, and the sealing part 22 is located on the side of the main body 21 facing the terminal shell 1. The main body 21 is connected with the outer wall of the terminal shell 1, and the connection can be adhesive. The sealing part 22 is located in the mounting hole 10. The material of the camera decoration 2 can be aluminum alloy, steel, glass, plastic, and composite materials formed by the above materials.

[0066] The sealing part 3 is connected with the inner wall of the terminal shell 1 and the end wall of the sealing part 22 away from the main body 21. The material of the sealing part 3 can be stainless steel, plastic, and aluminum alloy. The connection between the sealing part 3 and the terminal shell 1 can be adhesive, and the connection between the sealing part 3 and the sealing part 22 can be welding, adhesive, clamping, and screw connection. For example, as shown, Figure 8 As shown, the sealing part 3 and the sealing part 22 can be connected by a screw b. In order to reduce the thickness space occupied by the screw b in the terminal, the side of the sealing part 3 away from the sealing part 22 can have a counterbore 31, and the head of the screw b is located in the counterbore 31, thereby reducing the length of the head of the screw b protruding from the sealing part 3. The sealing part 3 can also be called a reinforcing part, a cover plate, a bottom plate, etc. It can be understood that the sealing part 3 can be a plate structure.

[0067] In addition, in the terminal, there is also a support structure on the bottom side of the sealing part 3, which supports the sealing part 3 to balance the external force received by the camera decoration 2, and the support structure is an antenna support or a camera support, etc.

[0068] In a possible implementation, in order to improve the sealing performance of the camera decoration mounting structure, an annular filling space a is formed between the sealing part 22 and the hole wall of the mounting hole 10. The camera decoration mounting structure further comprises a filler 4 filled in the filling space a, and the sealing part 3 seals the opening of the filling space a.

[0069] The filler 4 is a sealing and adhesive material, which can be an adhesive such as hot melt adhesive, thermosetting adhesive, silicone adhesive, UV adhesive, AB adhesive, or an elastic filling body such as a rubber ring.

[0070] The camera decoration 2 in the camera decoration mounting structure provided by the embodiment of the present application is connected with the outer wall of the terminal shell 1, so that the camera decoration 2 does not occupy too much thickness space in the terminal, which is beneficial to the thin design of the terminal.

[0071] In addition, by filling the filler 4 between the sealing part 22 of the camera decoration 2 and the hole wall of the mounting hole 10, the sealing between the camera decoration 2 and the terminal shell 1 is facilitated, and the sealing part 3 can play a pressure maintaining role on the filler 4, thereby improving the sealing effect of the filler 4.

[0072] Furthermore, by connecting the sealing member 3 with the inner wall of the terminal shell 1 and the end wall of the sealing part 22, the strength of the camera decoration member mounting structure can be enhanced, and the risk of the camera decoration member 2 falling off can be reduced. Moreover, the stress state of the terminal shell 1 is improved, and the risk of the terminal shell 1 being damaged by stress is reduced.

[0073] For example, if the sealing member 3 does not exist, when the camera decoration member 2 is impacted by external force, the camera decoration member 2 will give a great impact force to the terminal shell 1. However, the existence of the sealing member 3 can convert the impact force received by the terminal shell 1 into symmetrical pressure between the inside and outside of the terminal shell 1 as much as possible, thereby reducing the possibility of the terminal shell 1 being damaged.

[0074] Moreover, when the camera decoration member 2 is impacted by external force, the reaction force given by the support structure of the camera decoration member 2 to the sealing member 3 can be uniformly dispersed through the sealing member 3 and the adhesive c between the sealing member 3 and the terminal shell 1, thereby avoiding the occurrence of stress concentration and further reducing the possibility of the terminal shell 1 being damaged.

[0075] In a possible implementation, as shown in Figure 7 The opening of the filling space a gradually increases in the direction towards the sealing member 3.

[0076] In this way, the filling space a has an outer large and inner small structure, which facilitates the injection of the filler 4, and this structure also facilitates the pressure maintaining of the filler 4 by the sealing member 3, so that the filler 4 is more compact in the filling space a, thereby improving the sealing effect. On the other hand, the outer large and inner small structure makes it necessary to first extrude the large head portion of the filler 4 when the camera decoration member 2 has a tendency to fall off, which further enhances the anti-falling-off capability of the camera decoration member 2.

[0077] Regarding the implementation mode that the opening of the filling space a gradually increases in the direction towards the sealing member 3, the embodiments of the present application are not limited.

[0078] For example, as shown in Figure 7 The intersection area between the inner wall of the mounting hole 10 and the inner wall of the terminal shell 1 has a first chamfer structure 11. The intersection area between the side wall of the filling space a and the end wall of the sealing part 22 away from the main part 21 has a second chamfer structure 221.

[0079] The angle between the first chamfer structure 11 and the inner wall of the terminal shell 1 can be 45°, but is not limited thereto. The angle between the second chamfer structure 221 and the end wall of the sealing part 22 can be 45°-60°, but is not limited thereto.

[0080] Of course, the above implementation is only an example and does not constitute a limitation on the present application. For example, the first chamfer structure 11 and the second chamfer structure 221 can be replaced by a first rounded corner structure and a second rounded corner structure, respectively.

[0081] In a possible implementation, as shown in Figures 8-10 The side wall of the sealing portion 22 forming the filling space a can have a ring-shaped groove 222.

[0082] In this way, when the filler 4 is injected into the filling space a, the adhesion effect of the filler 4 inside the filling space a is better due to the presence of the ring-shaped groove 222. When the camera decoration 2 has a tendency to fall off, the part of the filler 4 located inside the ring-shaped groove 222 will hinder the camera decoration 2 from falling off, thereby reducing the risk of the camera decoration 2 falling off.

[0083] Moreover, the presence of the ring-shaped groove 222 also increases the surface area inside the filling space a, so that the contact area of the filler 4 with the sealing portion 22 of the camera decoration 2 is larger. The amount of the filler 4 filled into the filling space a is larger, and the sealing effect is better.

[0084] As to the specific form of the ring-shaped groove 222, the present application does not make any limitation. The shape of the cross section of the ring-shaped groove 222 includes but is not limited to the following:

[0085] As shown in Figure 8 The cross section of the ring-shaped groove 222 is in the shape of a circular arc.

[0086] As shown in Figure 9 The cross section of the ring-shaped groove 222 is in the shape of a rectangle.

[0087] As shown in Figure 10 The cross section of the ring-shaped groove 222 is in the shape of a trapezoid.

[0088] In order to better understand the camera decoration mounting structure provided by the present application, the structure of the camera decoration 2 and the sealing member 3 provided by the present application will be described in more detail as follows:

[0089] As shown in Figure 3 and Figure 4 The camera decoration 2 includes a main body portion 21 and a sealing portion 22, the sealing portion 22 at least includes a ring-shaped protrusion and is located on the side of the main body portion 21 facing the terminal housing 1. The main body portion 21 has a plurality of through holes 210, the plurality of through holes 210 are used for passing light, and the plurality of through holes 210 are located on the inner side of the sealing portion 22.

[0090] The adhesive c has a certain thickness, which can increase the gap between the body part 21 and the outer wall of the terminal shell 1. In order to reduce the gap between the body part 21 and the terminal shell 1, as shown in Figure 3 and Figure 6 , the body part 21 has a ring-shaped protrusion 211 at the edge of the side facing the terminal shell 1, and the adhesive c is located inside the ring-shaped protrusion 211, so that the ring-shaped protrusion 211 can shorten a part of the gap caused by the adhesive c.

[0091] The specific structure of the sealing member 3 changes with the camera decoration member 2, that is, the sealing member 3 is adaptively designed according to the camera decoration member 2. For example, as shown in Figure 5 , the sealing member 3 has a ring-shaped plate structure and is coaxial with the mounting hole 10. The center of the sealing member 3 has an avoiding hole 40 for avoiding the camera d.

[0092] Figure 5 The sealing member 3 shown in the middle is a square ring-shaped sealing member, and in actual application, it can also be a circular ring-shaped sealing member, etc., which is not limited by the embodiments of the application.

[0093] Next, referring to Figure 6 , the mounting process of the camera decoration member mounting structure provided by the embodiments of the application will be exemplarily described:

[0094] First, the body part 21 of the camera decoration member 2 and the outer wall of the terminal shell 1 are bonded together by the adhesive c. The bonding is achieved at the same time, and the first layer of sealing between the camera decoration member 2 and the terminal shell 1 is also achieved. The adhesive c can be double-sided tape, adhesive film, and point adhesive, etc.

[0095] Then, the filler 4 is injected into the gap (i.e. the filling space a) between the sealing part 22 of the camera decoration member 2 and the hole wall of the mounting hole 10 of the terminal shell 1, to achieve the second layer of sealing between the camera decoration member 2 and the terminal shell 1, and also to fix the camera decoration member 2 and the terminal shell 1.

[0096] Finally, the sealing member 3 is bonded to the inner wall of the terminal shell 1 by the adhesive c, and the sealing member 3 is fixed to the sealing part 22 of the camera decoration member 2, and then the mounting process of the camera decoration member mounting structure is completed.

[0097] The camera decoration member mounting structure provided by the embodiments of the application has at least the following beneficial effects:

[0098] (1) The camera decoration member 2 provided by the embodiments of the application is connected with the outer wall of the terminal shell 1, which belongs to an externally assembled camera decoration member mounting method, and can save the internal thickness space of the terminal.

[0099] (2) The first layer sealing of the camera decoration piece 2 and the terminal shell 1 is realized by the adhesion of the main body part 21 of the camera decoration piece 2 and the outer wall of the terminal shell 1, and the second layer sealing of the camera decoration piece 2 and the terminal shell 1 is realized by filling the filler 4 between the sealing part 22 of the camera decoration piece 2 and the inner wall of the mounting hole 10, and the double-layer sealing structure design realizes the IP68 protection level.

[0100] (3) By setting the sealing part 3, the falling risk of the camera decoration piece 2 can be reduced, and the stress condition of the terminal shell 1 is improved, and the possibility of damage of the terminal shell 1 under stress is reduced. At the same time, the sealing part 3 has a pressure maintaining effect on the filler 4, which can improve the sealing effect of the filler 4.

[0101] (4) By setting the opening of the filling space a gradually increasing along the direction towards the sealing part 3, the pressure maintaining effect of the sealing part 3 on the filler 4 can be improved, and the sealing effect can be improved. And this structure also reduces the falling risk of the camera decoration piece 2.

[0102] (5) By setting the annular groove 222 on the side wall of the filling space a of the sealing part 22, the adhesion ability of the filler 4 can be improved, and the possibility of falling of the camera decoration piece can be reduced.

[0103] The application also provides a terminal, which comprises the camera decoration piece mounting structure provided by the application.

[0104] The terminal provided by the application includes but is not limited to mobile phones, tablets and the like.

[0105] The scheme shown in the application can make the sealing effect of the terminal better by applying the camera decoration piece mounting structure provided by the application in the terminal.

[0106] And since the camera decoration piece mounting structure does not occupy a large thickness space of the terminal, the terminal can be made thinner, which is beneficial to the thin design of the terminal.

[0107] Furthermore, when the camera decoration piece 2 is stressed and collides, the terminal shell 1 is not easily damaged, and the camera decoration piece 2 is not easily fallen off.

[0108] The above is only an optional embodiment of the application, and does not limit the application. Any modification, equivalent replacement, improvement, etc. made within the principles of the application shall be included in the protection scope of the application.
