[0002] With the continuous development of smart electronic products, electronic devices equipped with curved screens have gained market favor due to their unique visual effects and user experience. While flat-screen phones can use adhesive to secure the screen, it's difficult to achieve a good hold on curved screens. To ensure a stable connection between the curved screen and the back cover, the two sides of the curved screen are typically attached to the back cover with glue. However, customers lack the equipment to disassemble this glue, making it a non-removable connection method for ordinary users. When a curved screen is damaged or malfunctions, ordinary users cannot replace it themselves and must rely on professional repair shops, increasing repair costs. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose an electronic device.

[0005] The electronic device of this application embodiment includes a curved screen, a connecting frame, and a back cover.

[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] like Figures 1 to 4 As shown, the electronic device 100 of this application embodiment includes a curved screen 1, a connecting frame 2, and a back cover 3. The curved screen 1 has a flat portion 101 and a curved portion 102, the curved portion 102 being connected to both sides of the flat portion 101, and the curved portion 102 having a first connecting surface 1021. The connecting frame 2 has opposing second connecting surfaces 201 and third connecting surfaces 202, the second connecting surface 201 facing the curved screen 1 and connected to the first connecting surface 1021 by adhesive. The back cover 3 has a fourth connecting surface 301 facing the connecting frame 2, each of the third connecting surface 202 and the fourth connecting surface 301 being a plane, and the third connecting surface 202 and the fourth connecting surface 301 being bonded together by adhesive.

[0025] The electronic device 100 of this application embodiment effectively ensures the connection stability of the curved screen 1 by using adhesive to connect the first connecting surface 1021 of the curved screen 1 to the second connecting surface 201 of the connecting frame 2. Since the third connecting surface 202 of the connecting frame 2 and the fourth connecting surface 301 on the back cover 3 are both flat, the third connecting surface 202 and the fourth connecting surface 301 are bonded together with adhesive. While effectively ensuring the connection stability between the connecting frame 2 and the back cover 3, the user can also remove the connecting frame 2 bonded to the back cover 3 without the need for special disassembly equipment. Therefore, when the curved screen 11 is damaged or needs to be replaced, the user can handle it independently and replace the screen himself without relying on professional repair institutions, which greatly improves the convenience of repair and reduces repair costs.

[0026] In some embodiments, at least a portion of the curved portion 102 facing the back side of the connecting frame 2 in its thickness direction constitutes a first connecting surface 1021, and the second connecting surface 201 is a curved surface and is adapted to the first connecting surface 1021.

[0027] For example, a portion of the bent portion 102 facing the back of the connecting frame 2 in its thickness direction constitutes the first connecting surface 1021, or the entire portion of the bent portion 102 facing the back of the connecting frame 2 in its thickness direction constitutes the first connecting surface 1021.

[0028] Due to the curved surface adaptation design of the first connecting surface 1021 and the second connecting surface 201, coupled with the bonding effect of adhesive 4, the connection stability between the curved screen 1 and the connecting frame 2 is improved, making the overall structure more robust. The curved design of the connecting surfaces allows for a better fit, reducing potential gaps and thus improving the sealing performance of the electronic device 100, contributing to waterproofing and dustproofing. Although adhesive 4 is used for connection, the optimized design allows for relatively easy separation of the curved screen 1 and the connecting frame 2 during maintenance, reducing maintenance difficulty and cost.

[0029] In some embodiments, the second connecting surface 201 is provided with a glue tank 2011 for receiving glue 4.

[0030] The second connecting surface 201 is provided with a dedicated adhesive groove 2011, which guides the adhesive 4 to a specific area during the connection process, thereby ensuring the uniform distribution of the adhesive 4. The adhesive groove 2011 helps to precisely control the position and amount of adhesive 4, avoiding overflow of adhesive 4 in unnecessary areas and ensuring the accuracy and efficiency of the connection. At the same time, when repairing or replacing the curved screen 1, the presence of the adhesive groove 2011 helps to quickly locate the position of the adhesive 4, simplifying the repair process and reducing the difficulty and cost of repair.

[0031] In some embodiments, the rear shell 3 is provided with a groove 302, the bottom surface of the groove 302 forms a fourth connecting surface 301, and part of the connecting frame 2 is located in the groove 302.

[0032] The interlocking design of the groove 302 and the connecting frame 2 provides additional mechanical fixation, which helps to enhance the overall structural stability of the electronic device 100 and reduce vibration and displacement during use. The presence of the groove 302 makes the connection between the connecting frame 2 and the back cover 3 more secure, and the connection strength is improved through the dual protection of physical interlocking and adhesive 5.

[0033] In some embodiments, the connecting frame 2 is provided with a first limiting part 203, and the rear shell 3 is provided with a second limiting part 303 for stopping the first limiting part 203 in the thickness direction of the rear shell 3.

[0034] The limiting parts prevent excessive compression of the adhesive 5 between the third connecting surface 202 and the fourth connecting surface 301, thus improving the connection reliability between the connecting frame 2 and the rear shell 3. Furthermore, they limit excessive movement of the connecting frame 2 on the rear shell 3, enhancing connection stability and ensuring the structural integrity of the electronic device 100 during normal use. The presence of the limiting parts prevents displacement of the connecting frame 2 due to vibration or other external factors, thereby improving the safety of the electronic device 100 and preventing potential damage or malfunction. The limiting parts also simplify the assembly process, as they provide clear positioning points, making the installation of the connecting frame 2 more accurate and faster.

[0035] In some embodiments, the first limiting portion 203 has a first arcuate surface 2031 protruding toward the curved screen 1, and the second limiting portion 303 has a second arcuate surface 3031 protruding toward the first limiting portion 203, wherein the first arcuate surface 2031 and the second arcuate surface 3031 are adapted to each other.

[0036] The curved surface design provides better resistance to external forces, such as vibration or impact, thereby enhancing connection stability and preventing the connecting frame 2 from moving on the rear shell 3. Due to the curved surface, the connection structure can better distribute stress, reducing potential damage or malfunctions caused by poor connections and improving the safety of the electronic device 100.

[0037] In some embodiments, the connecting frame 2 is provided with one of a buckle 204 and a slot 304, and the rear shell 3 is provided with the other of a buckle 204 and a slot 304, with the buckle 204 and the slot 304 being snapped together.

[0038] The connecting frame 2 is equipped with a buckle 204 or a slot 304, while the rear shell 3 is equipped with a corresponding slot 304 or buckle 204. This allows the connecting frame 2 and the rear shell 3 to be mechanically engaged by the buckle 204 and the slot 304 to achieve a limiting effect, improving the assembly efficiency of the connecting frame 2. When maintenance or replacement of parts is required, the buckle 204 can be easily removed from the slot 304 without damaging the equipment structure, facilitating user operation, saving assembly and maintenance time, and improving work efficiency.

[0039] In some embodiments, the connecting frame 2 is generally rectangular, and at least one of the first long side 205 and the second long side 206 of the connecting frame 2 is provided with a plurality of buckles 204 at intervals.

[0040] like Figure 1As shown, the rectangular design of the connecting frame 2 provides structural stability and a regular mounting surface, facilitating alignment and connection with other components. The arrangement of multiple clips 204 provides more connection points, helping to distribute stress at the joints and enhancing the overall structural stability. Since the clips 204 are distributed along the entire long side, this helps improve the precision and accuracy of assembly during the connection process. The presence of multiple clips 204 makes it easier to locate and manipulate the connection points when maintenance or component replacement is required, simplifying the maintenance process.
