[0027] The utility model provides a smart device with an integrated flexible circuit board 500, including a screen module 100, a body 200, a main board 300, a sub-board 400 and an integrated flexible circuit board 500, wherein the screen module 100 is arranged on one side of the body 200, and the main board 300 and the sub-board 400 are both arranged on the side of the body 200 away from the screen module 100; the integrated flexible circuit board 500 includes a first flexible circuit board 1 connected between the main board 300 and the sub-board 400 and a second flexible circuit board 2 connected between the main board 300 and the screen module 100, wherein the first flexible circuit board 1 includes a first The wiring extension portion 11 and the first main board connection portion 12 and the sub-board connection portion 13 are arranged at both ends of the first wiring extension portion 11, and the second flexible circuit board 2 includes a second wiring extension portion 21 and a second main board connection portion 22 and a screen connection portion 23 are arranged at both ends of the second wiring extension portion 21; the first main board connection portion 12 and the second main board connection portion 22 are both electrically connected to the main board 300, the first wiring extension portion 11 and the second wiring extension portion 21 are an integrally formed structure, the sub-board connection portion 13 is electrically connected to the sub-board 400, and the screen connection portion 23 is electrically connected to the screen module 100.

[0028] In this embodiment, functional components such as a USB interface, a motor and a speaker are arranged on the sub-board 400, and both the sub-board 400 and the screen module 100 need to achieve electrical connection by pulling a flexible circuit board 500 onto the main board 300. This embodiment simplifies production costs by integrating the first flexible circuit board 1 connecting the main board 300 and the sub-board 400 and the second flexible circuit board 2 connecting the main board 300 and the screen assembly into an integrated structure. Compared with the two separate flexible circuit boards 500 that need to be separately installed in the smart device, the integrated flexible circuit board 500 also improves assembly efficiency and reduces labor costs.

[0029] Specifically, the principle of integration is to make the external bearing structure (i.e., substrate) of the integrated flexible circuit board 500 wider to accommodate more internal wiring, wherein the interior of the flexible circuit board 500 is divided into two areas, one side for the wiring of the first flexible circuit board 1, and the other side for the wiring of the second flexible circuit board 2. According to the actual test structure, a gap of 0.5MM-1MM is separated in the middle, so that the wiring on the first flexible circuit board 1 and the second circuit board will not interfere with each other.

[0030] Furthermore, the screen module 100 is used to interact with the user and provide a visual interface. The body 200 is the main structure of the smart device, carrying various components such as the screen module 100, the main board 300, the sub-board 400 and the integrated flexible circuit board 500. The main board 300 is the core component of the smart device, responsible for controlling and managing the various functions of the device. It integrates key components such as processors, memory, storage, and is the hub of device computing and data processing. The sub-board 400 is used to connect and manage some peripheral devices or extended functions, such as USB interfaces, motors and speakers. The integrated flexible circuit board 500 is a key component for connecting various components in the smart device. It has excellent flexibility and bendability, and can easily connect the main board 300, the sub-board 400 and the screen module 100 to achieve signal and data transmission. The design of the integrated flexible circuit board 500 makes the internal structure of the smart device more concise and compact, reduces the additional space required for the traditional split flexible circuit board 500, and improves the efficiency and cost of assembly and production.

[0031] Furthermore, the first mainboard connection part 12 and the second mainboard connection part 22 are a specific area on the integrated flexible circuit board 500, and each of them at least includes a connector or a pad corresponding to the interface on the mainboard 300. This part of the structure is connected to the mainboard 300 connection part through internal wiring to ensure that the signals and data between the mainboard 300 and the integrated flexible circuit board 500 can be accurately transmitted. The sub-board 400 connector is a specific area on the integrated flexible circuit board 500, which at least includes a connector or a pad corresponding to the interface on the sub-board 400. Similarly, the screen connection part 23 includes at least a connector or a pad corresponding to the interface on the screen module 100, wherein, in this embodiment, a BTB connector is provided on the screen module 100 to be snap-fitted with the screen connection part 23, and a screen IC responsible for layout and some electronic materials are also provided on the screen connection part 23.

[0032] In this embodiment, the first mainboard connection portion 12 is electrically connected to the sub-board connection portion 13 through the internal wiring of the first wiring extension portion 11, and the second mainboard connection portion 22 is electrically connected to the screen connection portion 23 through the internal wiring of the second wiring extension portion 21. Through the internal wiring, signals and data can be accurately and quickly transmitted between different components, ensuring the normal operation and efficient performance of the device.

[0033] In this embodiment, a sheet metal hole 201 is provided on the fuselage 200, and the second wiring extension part 21 is passed through the sheet metal hole 201, and the two ends of the second wiring extension part 21 extend toward the two sides of the fuselage 200 respectively. The sheet metal hole 201 is a through hole structure. The setting of the sheet metal hole 201 optimizes the connection mode between the flexible circuit board 500 and the fuselage 200, so that the second wiring extension part 21 can pass through the fuselage 200, thereby realizing the connection with the screen module 100, which not only simplifies the assembly process and reduces the assembly difficulty, but also improves the stability and reliability of the connection. In addition, by extending the two ends of the second wiring extension part 21 toward the two sides of the fuselage 200 respectively, the layout of the flexible circuit board 500 on the fuselage 200 is more reasonable, avoiding the crossing and interference between the lines, and making the circuit board more compact as a whole, reducing the occupied space, which is conducive to realizing the miniaturization and lightweight of the device.

[0034] In this embodiment, a positioning hole 23a is also provided on the screen connection part 23, and a positioning protrusion 101 that cooperates with the positioning hole 23a is provided on the screen module 100. For the positioning hole 23a and the positioning protrusion 101, common processing methods such as injection molding and stamping molding can be adopted. The matching design of the positioning hole 23a and the positioning protrusion 101 significantly improves the accuracy and efficiency of assembly, so that the screen connection part 23 can be accurately installed at the predetermined position of the screen module 100, avoiding assembly errors caused by position deviation. At the same time, this design also simplifies the assembly process, reduces the skill requirements for operators, and thus improves production efficiency.

[0035] In this embodiment, the first mainboard connection portion 12 is provided with a first bending area 12a, the second mainboard connection portion 22 is provided with a second bending area 22a, and the sub-board connection portion 13 is provided with a third bending area 13a. The provision of each bending area enables the flexible circuit board 500 to be flexibly bent during assembly to adapt to the complex structure and space limitations inside the device, which not only simplifies the assembly process, reduces the difficulty of operation, but also improves the accuracy and efficiency of assembly.

[0036] In this embodiment, a fourth bending area 23 b connected to the screen module 100 is disposed on the screen connecting portion 23 .

[0037] In this embodiment, the body 200 is provided with a limiting groove 202 for accommodating the second flexible circuit board 2. The limiting groove 202 is designed so that one side of the second flexible circuit board 2 can be firmly limited on the edge of the limiting groove 202, thereby preventing the integrated circuit board 500 from shaking or shifting during the use of the device, and helping to ensure the stability and reliability of the integrated circuit board 500.

[0038] In this embodiment, a gap for preventing interference is provided between the internal wiring of the first wiring connection part and the internal wiring of the second wiring connection part, and the distance of the gap is set to 0.5mm to 1mm. A suitable wiring gap can reduce the attenuation and distortion during signal transmission and ensure signal quality. At the same time, it also helps to reduce electromagnetic interference (EMI) and electromagnetic radiation (EMR), improve the electromagnetic compatibility of the equipment, and enable the equipment to still operate stably in a complex electromagnetic environment. According to actual tests, a gap of 0.5MM-1MM is opened in the middle gap, and the wiring on the first flexible circuit board 1 and the second circuit board can be achieved without interfering with each other. As a preferred embodiment, there is a gap of 1mm between the internal wiring of the first wiring connection part and the internal wiring of the second wiring connection part.

[0039] In this embodiment, a third wiring extension portion 14 is disposed on the first wiring extension portion 11 , and the third wiring extension portion 14 is disposed perpendicular to the second wiring extension portion 21 .

[0040] In this embodiment, a clearance interval is provided between the first mainboard connection portion 12 and the second mainboard connection portion 22, and the distance of the clearance interval is set to 14.85 mm to 15.15 mm. The design of the clearance interval between the first mainboard connection portion 12 and the second mainboard connection portion 22 takes into account the manufacturing and assembly process of the equipment. The clearance interval of 14.85 mm to 15.15 mm is neither too narrow to increase the manufacturing difficulty nor too spacious to waste space. It makes the manufacturing and assembly process of the flexible circuit board 500 smoother and improves production efficiency. As a preferred embodiment, there is a 14.97 mm clearance interval between the first mainboard connection portion 12 and the second mainboard connection portion 22.

[0041] The present invention is described in more detail below by way of examples. However, the following examples are merely illustrative and should not be construed as limiting the scope of the present invention. Obviously, those skilled in the art may make any changes, improvements or modifications without violating the spirit of the present invention.

[0042] This example proposes a production process of a smart device with an integrated flexible circuit board 500. In the early stage of project design, the wiring interface definition of the mainboard 300 is first confirmed, and the PIN angle sequence is confirmed. According to the wiring interface definition of the mainboard 300 and the PIN angle sequence, the first flexible circuit board 1 connecting the mainboard 300 and the sub-board 400 is designed. The first flexible circuit board 1 is integrated into the second flexible circuit board 2 connecting the mainboard 300 and the screen module 100 through the integrally formed first wiring extension part 11 and second wiring extension part 21. The integration method only needs to divide two areas, with the second flexible circuit board 2 on the left and the first flexible circuit board 1 on the right. According to actual test results, a gap of 0.5MM-1MM is separated in the middle, so that the wiring on the first flexible circuit board 1 and the second circuit board can be non-interfering with each other. When the whole machine is assembled in the factory, it is only necessary to place the integrated flexible circuit board 500 on the body 200, and pass one end of the second wiring extension part 21 connected to the screen connection part 23 through the sheet metal hole 201, and then snap the screen connection part 23 and the BTB connector on the screen module 100 together to complete the assembly. This design can not only save assembly costs, but also save the mold opening costs of the first flexible circuit board 1, and is easy to assemble.

[0043] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
