In the related art, multiple electronic components are arranged in the electronic device, and the connection between the multiple electronic components is realized through wires.

[0003] For the above related technology, the arrangement of multiple wires needs to occupy the space inside the device, which is easy to cause waste of space. CONTENT OF THE UTILITY MODEL

[0004] In order to improve the space utilization, the present application provides an integrated stacking design structure and a whole machine.

[0007] By adopting the above technical solution, multiple functional units are integrated on the same mainboard, and internal signal lines are used for interconnection, which not only reduces the physical interval between different functional units, but also effectively shortens the signal transmission path. This compact layout significantly improves the overall space utilization of the system and reduces the overall volume of the device. At the same time, since the signal lines are all wired inside the mainboard, the interference of the external environment on the signal can be effectively reduced, and the stability and reliability of signal transmission are improved. In addition, through reasonable layout design, the key signal lines are better protected, further enhancing the performance of the system.

[0008] Optionally, the multiple functional units at least include an AP processing unit, a CP communication unit and a radio frequency antenna unit.

[0009] By adopting the above technical solution, the AP processing unit, the CP communication unit and the radio frequency antenna unit are integrated on the same mainboard and interconnected through signal lines, realizing efficient cooperative work between the functional units. This integrated design not only significantly reduces the internal space occupation of the whole machine, but also optimizes the signal transmission path, shortens the length of the signal lines, reduces the risk of signal attenuation and interference, thereby improving the stability and reliability of the system. In addition, by reasonably arranging each functional unit, the effective isolation and protection of the key signal are ensured, further enhancing the overall performance of the system.

At the same time, the split design of the shell enables the radio frequency antenna unit to achieve good matching at different frequency bands, ensuring stable operation of the antenna at 5G / 4G / 3G / 2G full frequency bands. In addition, this design can effectively reduce the mutual interference between antennas, further improving the overall performance and reliability of the system.
