[0035] The following details various embodiments of this utility model, illustrated with accompanying drawings. Besides these detailed descriptions, this utility model can be widely implemented in other embodiments. Any easy substitutions, modifications, or equivalent changes to the described embodiments are included within the scope of this utility model, and the claims shall prevail. In the description of this specification, many specific details and implementation examples are provided to give the reader a more complete understanding of this utility model; however, these specific details and implementation examples should not be considered as limitations of this utility model. Furthermore, well-known steps or elements are not described in the details to avoid creating unnecessary limitations on this utility model.

[0036] Mobile terminals, such as laptops, include a casing, which includes an upper shell and a lower shell. The upper shell may house a display screen and other related structures, while the lower shell may house a motherboard, CPU, memory, hard drive, graphics card, power supply, cooling system, and other related structures. This is a technology known to those skilled in the art.

[0037] This utility model adopts a new design concept and structure for the antenna structure, feet, and related parts of the casing of a mobile terminal. It should be noted that the mobile terminal using the antenna structure of this utility model can be a networked smart home appliance with feet, such as a laptop, speaker, television, or the main unit of a robot vacuum cleaner. The antenna structure is not limited to Wi-Fi; it can also be 4G, 5G, 6G, Bluetooth, etc. In the following embodiments, the mobile terminal antenna structure of this utility model will be used in a laptop for detailed description. However, it should be noted that the same structure can be applied to other networked devices with feet.

[0038] like Figure 1 and Figure 2As shown, the mobile terminal antenna structure of this utility model includes a mobile terminal housing 100, feet 200, and an antenna assembly 300. The mobile terminal housing 100 includes a bottom shell 110. The antenna assembly 300 includes an antenna motherboard (not shown), a connecting cable 310, and a radiating antenna 320. The antenna motherboard can be housed within the mobile terminal housing 100. The connecting cable 310 connects the antenna motherboard and the radiating antenna 320. The radiating antenna 320 is mounted on the feet 200, which are connected to the bottom shell 110. This utility model, through clever placement of the radiating antenna 320, maintains the integrity of the laptop's appearance while ensuring stable performance of the mobile terminal antenna structure.

[0039] In some embodiments of this utility model, the radiating antenna 320 adopts LDS (Laser-Direct-structuring) laser direct forming technology, which uses computer-controlled laser to project the laser onto the foot pad 200 according to the trajectory of the conductive pattern. It has stable performance, strong anti-interference ability, and a simplified and environmentally friendly manufacturing process.

[0040] The antenna motherboard is a circuit board that transmits and interacts with other hardware (such as CPU, memory, etc.). It is responsible for processing the receiving and sending commands of antenna signals. The antenna motherboard can be a printed circuit board or a flexible circuit board. Connector 310 connects the antenna motherboard to the radiating antenna 320, transmitting the electrical signals generated by the antenna motherboard to the radiating antenna 320 without loss, and simultaneously transmitting the antenna signals received by the radiating antenna 320 back to the antenna motherboard for processing. For example, in this embodiment, the radiating antenna 320 is a WIFI antenna. The radiating antenna 320 converts the electrical signals from the antenna motherboard into electromagnetic waves and radiates them into the air, enabling wireless communication with WIFI hotspots or other devices. At the same time, it can also efficiently capture WIFI signals in the air and convert them into electrical signals to be transmitted back to the antenna motherboard.

[0041] This invention laser-forms the radiating antenna 320 onto the foot pad 200, which, while meeting the requirements for antenna coverage, penetration, and stability, does not damage the overall appearance of the laptop.

[0042] In this utility model, such as Figure 3 and Figure 4 As shown, the radiating antenna 320 and the foot pad 200 are two-color integrated molded parts, which reduces the number of parts, simplifies the assembly process, and helps to reduce costs.

[0043] The foot pad 200 includes a connecting surface S facing the bottom shell 110, and the radiating antenna 320 is formed on the connecting surface S. When the foot pad 200 is attached to the bottom shell 110, the connecting surface S is opposite to the bottom shell 110, and the two are engaged. Figure 1When viewed from the bottom of the bottom shell 110, the connecting line 310 or the radiating antenna 320 will not be exposed, resulting in a strong overall integrity.

[0044] like Figure 3 As shown, the bottom shell 110 includes a connecting wire outlet 111 through which the connecting wire 310 passes. One end of the connecting wire 310 is connected to the antenna main board located inside the bottom shell, and after passing through the connecting wire outlet 111, it is connected to the radiating antenna 320.

[0045] In some embodiments of this utility model, the bottom shell 110 and the foot pad 200 are bonded together. For example, the bottom shell 110 is provided with a bonding area, and the foot pad 200 is bonded to the bonding area of ​​the bottom shell 110, with the bonding surface S of the foot pad 200 facing the bonding area of ​​the bottom shell 110.

[0046] In some embodiments of this utility model, the bottom shell 110 and the foot pad 200 are connected by a limiting structure 400. The foot pad 200 and the bottom shell 110 are fixedly connected by the limiting structure 400, which is firm and stable and prevents displacement.

[0047] like Figure 3 and Figure 4 As shown, the limiting structure 400 includes multiple limiting holes 410 and multiple corresponding limiting posts 420. The limiting posts 420 are inserted and fixed in the limiting holes 410 to fix the foot pad 200 to the bottom shell 110. In this embodiment, the limiting holes 410 are provided on the bottom shell 110, and the limiting posts 420 are provided on the foot pad 200.

[0048] In some embodiments, the foot pad 200 can be more securely fixed to the bottom shell 110 by a combination of adhesive bonding and limiting fixation, which can solve the problem of antenna signal connection failure or performance instability caused by the displacement of the foot pad 200.

[0049] The limiting structure 400 can also take various other structural forms to achieve precise positioning and fixation. For example, in other embodiments, the limiting structure 400 can be a mating boss and groove, a mating key and keyway, or bolt fixing, etc., which can be selected by comprehensively considering factors such as specific application scenarios, positioning accuracy requirements, assembly processability, and cost.

[0050] The mobile terminal antenna structure of this utility model cleverly sets the radiating antenna 320 on the foot pad 200, and the mobile terminal shell 100 can be set as an all-metal structure, so as to maintain the integrity of the overall appearance of the laptop while ensuring the working performance of the antenna structure.

[0051] In other embodiments of this utility model, the radiating antenna 320 of the mobile terminal antenna structure adopts an FPC or PCB antenna structure and is attached to the inner surface of the foot pad 200 with double-sided adhesive, which can also maintain the integrity of the overall appearance of the laptop.

[0052] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
