[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] The present application embodiment discloses a membrane assembly for a mobile phone telescopic lens. Figures 1 to 3The membrane assembly for the mobile phone telescopic lens includes a mounting ring 2 and a movable ring 3. Specifically, the mounting ring 2 is in the shape of a circular ring, and the mounting ring 2 is coaxially sleeved on the fixed part of the mobile phone telescopic lens, and there is a predetermined gap between the inner wall of the mounting ring 2 and the fixed part, and the mounting ring 2 is made of metal, preferably aluminum alloy; the movable ring 3 is also in the shape of a circular ring, and the inner diameter of the movable ring 3 is smaller than the inner diameter of the mounting ring 2, the movable ring 3 is coaxially arranged with the mounting ring 2, and the outer side wall of the movable ring 3 is slidably connected with the inner side wall of the mounting ring 2, so that the movable ring 3 can extend or retract into the mounting ring 2 along the axis of the mounting ring 2, and an abutment ring 31 is arranged on the inner side wall of the movable ring 3, the abutment ring 31 is coaxially arranged with the movable ring 3, and the abutment ring 31 is integrally arranged at the upper side edge of the inner side wall of the movable ring 3, the lower end of the abutment ring 31 is used to abut with the extending part of the telescopic lens, and the abutment ring 31 and the movable ring 31 are connected to each other. The rings 3 are all made of metal, preferably aluminum alloy. When the membrane assembly 1 is installed on the telescopic lens of the mobile phone, the membrane assembly 1 is in a state of being mounted on the telescopic lens as a whole. When the user turns on the camera to take pictures, the protruding part of the telescopic lens will extend out of the fixed part. At this time, the protruding part will abut against the abutting ring 31 on the movable ring 3, and drive the abutting ring 31 to extend together. At this time, the movable ring 3 will extend from the mounting ring 2 under the action of the protruding part, so when using the telescopic lens to take pictures, the movable ring 3 will always cover the side of the protruding part. Since the abutting ring 31 also has a certain thickness, the abutting ring 31 will also protect the edge of the mirror surface of the protruding part, so that when the mobile phone is placed, external objects will not directly contact the mirror surface of the protruding part, thereby minimizing scratches, bumps, etc. on the protruding part, and thus minimizing damage to the telescopic lens.
[0027] An upper blocking ring 21 is integrally provided on the inner wall of the mounting ring 2, and the upper blocking ring 21 is arranged at the upper edge of the mounting ring 2. The upper blocking ring 21 is coaxially arranged with the mounting ring 2. A lower blocking ring 32 is integrally provided on the outer wall of the movable ring 3, and the lower blocking ring 32 is arranged at the lower edge of the movable ring 3. When the movable ring 3 slides relative to the mounting ring 2, the outer wall of the lower blocking ring 32 will slide and abut against the inner wall of the mounting ring 2. When the movable ring 3 extends out of the mounting ring 2 to the maximum distance, the lower end face of the upper blocking ring 21 will abut against the upper end face of the lower blocking ring 32 to limit the extension of the movable ring 3. Thereby, the maximum moving distance of the movable ring 3 can be limited without affecting the extension of the movable ring 3, and the movable ring 3 can be prevented from being disconnected from the mounting ring 2 as much as possible.
[0028] A first adhesive layer 4 is provided on the lower end surface of the mounting ring 2, and the first adhesive layer 4 is used to connect with the bottom shell of the mobile phone so that the membrane assembly 1 can be stably mounted on the mobile phone to protect the telescopic lens. At the same time, a second adhesive layer 5 is provided on the lower side surface of the abutment ring 31, and the second adhesive layer 5 is used to connect with the extension portion of the telescopic lens so that the extension portion and the movable ring 3 always move synchronously to avoid the movable ring 3 from moving around when the telescopic lens is not in use. The first adhesive layer 4 and the second adhesive layer 5 can both be in the form of double-sided tape.
[0029] In this embodiment, in order to keep the membrane assembly 1 and the telescopic lens in a certified state when the telescopic lens is not in use, when the movable ring 3 is retracted into the mounting ring 2, the upper end surface of the movable ring 3 and the upper end surface of the abutting ring 31 are flush with the upper end surface of the mounting ring 2. Therefore, when the telescopic lens is not in use, the upper side of the membrane assembly 1 as a whole is in a flat state, which can enhance the appearance on the one hand and reduce the space occupied by the membrane assembly 1 on the other hand.
[0030] The present application also discloses a telescopic lens film, referring to Figures 1 to 3 , including the above-mentioned membrane assembly 1 and a glass layer 6, the glass layer 6 is arranged on the upper end surface of the abutment ring 31, and the glass layer 6 is coaxially arranged with the abutment ring 31, and the glass layer 6 completely covers the middle penetration part of the abutment ring 31, the setting of the glass layer 6 can play a dustproof effect, and at the same time, the mirror part of the telescopic lens can be protected to prevent scratches; the glass layer 6 is embedded in the abutment ring 31 so that the upper end surface of the glass layer 6 is flush with the upper end surface of the abutment ring 31, which enhances the appearance and reduces the space occupied by the telescopic lens membrane, and the abutment ring 31 is provided with a third adhesive layer 7 at the connection with the glass layer 6, and the third adhesive layer 7 can also be in the form of double-sided tape to facilitate the installation of the glass layer 6.
[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
