Currently, some smart wearable devices are equipped with functions such as Bluetooth, GPS, Wi-Fi, and NFC. To achieve stable communication for these functions, antennas on different frequency bands need to be configured in the smart wearable devices.

[0003] Currently, most smart wearable devices use LDS (Laser Direct Structuring) antennas, which involve forming conductive lines on the surface of the device's frame to create an antenna. Furthermore, metal decorative elements are often placed on the outer side of the frame, acting as radiators for the antenna and enhancing its signal transmission and reception capabilities.

[0004] However, if the LDS antenna in the middle frame does not meet the requirements during debugging, the entire middle frame needs to be remade. The structure of the middle frame is relatively complex, and the remaking is difficult, resulting in high modification costs. Utility Model Content

[0037] This utility model discloses an intelligent host and an intelligent wearable device. The bracket has a relatively simple structure, the first antenna is easy to remake, and the modification cost can be reduced.

[0038] Example 1

[0039] Please see Figure 1 This is a schematic diagram of the structure of a smart host 100 provided in Embodiment 1 of the present utility model. The smart host 100 includes a middle frame 10, a circuit board 20 and a bracket 30. The circuit board 20 is disposed inside the middle frame 10, and the bracket 30 is disposed on the upper surface of the middle frame 10. A first metal line is formed on the surface of the bracket 30 facing the middle frame 10. The first metal line (not shown) is configured as at least part of the first antenna and is electrically connected to the circuit board 20.

[0040] In this embodiment, a circuit board 20 is installed inside the middle frame 10, and a bracket 30 is located on the upper surface of the middle frame 10. A first metal circuit is formed on the surface of the bracket 30, and the first metal circuit is configured as a first antenna. The first metal circuit is electrically connected to the circuit board 20 to realize communication between the first antenna and the circuit board 20. In this way, when the first antenna needs to be rebuilt after debugging, the bracket 30 can be reset separately, reducing the difficulty of resetting the first antenna and thus reducing the modification cost.

[0041] Alternatively, the metal lines formed on the support 30 may be formed using LDS process or PDS process (Printed Direct Structuring), etc., and this embodiment does not specifically limit this.

[0042] In some embodiments, such as Figure 1 and Figure 2As shown, the smart host 100 also includes a metal component 40 integrally formed with the middle frame 10. The metal component 40 further includes a first metal component 41. One end of the first metal component 41 protrudes from the upper surface of the middle frame 10 and is electrically connected to the first metal circuit. The other end of the first metal component 41 extends through the middle frame 10 and into the middle frame 10, and is electrically connected to the circuit board 20. Thus, by having one end of the first metal component 41 protruding from the upper surface of the middle frame 10, the connection difficulty between the first metal circuit and the first metal component 41 can be reduced. Furthermore, by having the other end of the first metal component 41 extend through the middle frame 10 and into the middle frame 10 and be electrically connected to the circuit board 20, electrical conductivity can be achieved between the first metal circuit, the first metal component 41 as a whole, and the circuit board 20, thereby enabling communication between the first antenna and the circuit board 20.

[0043] Optionally, the smart host 100 also includes a flexible pin 50, with its two ends electrically connected to the first metal line and the first metal component 41, respectively. Thus, by connecting the two ends of the flexible pin 50 to the first metal line and the first metal component 41, typical electrical continuity between the first metal line and the first metal component 41 can be achieved. Furthermore, the elasticity of the flexible pin 50 can buffer the force when the smart host 100 is dropped or subjected to impact, preventing the electrical continuity between the first metal line and the first metal component 41 from failing.

[0044] In some embodiments, such as Figure 2 and Figure 3 As shown, the metal component 40 includes a second metal component 42, which includes a first decorative portion 421 and a first extension portion 422. The first decorative portion 421 is located on the outer side of the middle frame 10, and the first extension portion 422 extends from the first decorative portion 421 to the upper surface of the middle frame 10 and connects to the first metal line. Thus, by extending from the first decorative portion 421 to the upper surface of the middle frame 10 and connecting to the first metal line, an electrical connection between the first metal line and the second metal component 42 can be achieved. Furthermore, by having the first decorative portion 421 located on the outer side of the middle frame 10, it can serve as a radiator for the first antenna, increasing the clearance of the first antenna.

[0045] Optionally, the second metal component 42 further includes a second extension 423, which extends from the first decorative portion 421 through the middle frame 10 and into the middle frame 10, and is electrically connected to the circuit board 20. Thus, by extending from the first decorative portion 421 through the middle frame 10 and into the middle frame 10 and electrically connecting to the circuit board 20, electrical conductivity can be achieved between the first metal circuit, the second metal component 42 as a whole, and the circuit board 20, thereby enabling communication between the first antenna and the circuit board 20.

[0046] In other words, there are two communication routes between the first antenna and the circuit board 20: the first metal part 41 and the second metal part 42. They can be set simultaneously or one of them can be set. This embodiment does not make specific limitations on this.

[0047] In some embodiments, such as Figure 2 and Figure 4 As shown, the metal component 40 includes a third metal component 43, which is configured as at least a portion of the second antenna. The third metal component 43 is located on the outer side of the middle frame 10 and is electrically connected to the circuit board 20. Thus, by configuring the third metal component 43 as at least a portion of the second antenna, the smart host 100 has multiple antennas of different frequency bands, thereby supporting different communication functions.

[0048] For example, the middle frame 10 and the metal component 40 are formed using NMT molding (Nano Molding Technology). In this way, by using NMT molding to prepare the middle frame 10 and the metal component 40, the metal component 40 can extend continuously and without interruption from the outside to the inside of the middle frame 10. The impedance of the first and second antennas is low, and the metal component 40 is tightly bonded to the middle frame 10, resulting in a high degree of sealing at the joint and good waterproof performance of the smart host 100.

[0049] In some embodiments, such as Figure 4 and Figure 5 As shown, the metal component 40 also includes a fourth metal component 44, which includes a second decorative portion 441 and a third extension portion 442. The second decorative portion 441 is disposed on the outer side of the middle frame 10, and the third extension portion 442 extends from the second decorative portion 441 to be flush with the upper surface of the middle frame 10. The third extension portion 442 has a first surface 442a flush with the upper surface of the middle frame 10. A second metal line 60 is formed on the first surface 442a and the upper surface of the middle frame 10. The second metal line 60 and the fourth metal component 44 are configured as at least part of a third antenna. In this way, on the one hand, by configuring the second metal line 60 and the fourth metal component 44 as at least part of the third antenna, the smart host 100 has multiple antennas of different frequency bands, thereby supporting different communication functions. On the other hand, by being disposed on the outer side of the middle frame 10, the second decorative portion 441 can serve as a radiator of the third antenna, increasing the clearance of the third antenna. Furthermore, the third extension 442 extends from the second decorative part 441 through the middle frame 10 into the middle frame 10 and is electrically connected to the circuit board 20, thereby enabling the second metal line 60 and the fourth metal part 44 to be electrically connected to the circuit board 20, thus enabling the third antenna to communicate with the circuit board 20.

[0050] For example, the fourth metal component 44 further includes a fourth extension 443, which extends from the second decorative portion 441 through the middle frame 10 and into the middle frame 10, and is electrically connected to the circuit board 20. Thus, by extending from the second decorative portion 441 through the middle frame 10 and into the middle frame 10 and being electrically connected to the circuit board 20, the fourth metal component 44 and the second metal line 60 can be electrically connected to the circuit board 20, thereby enabling communication between the third antenna and the circuit board 20.

[0051] For example, the second metal line 60 includes a transition portion 61 and a main body portion 62. The transition portion 61 covers the first surface 442a and the upper surface of the middle frame 10, and the main body portion 62 extends from the transition portion 61 and is distributed on the upper surface of the middle frame 10. The width of the transition portion 61 is greater than the width of the main body portion 62. In this way, by making the width of the transition portion 61 greater than the width of the main body portion 62, the transition portion 61 is widened at the boundary between the first surface 442a and the upper surface of the middle frame 10, reducing the risk of open circuits that may occur when the second metal line 60 is made of two different materials, the fourth metal component 44 and the middle frame 10.

[0052] Optionally, such as Figure 6 As shown, the width of the main body 62 is d1, and the width of the transition part 61 is d2, where 4d1 ≤ d2 ≤ 8d1. If the width d of the transition part 61 is... 2, If the width d2 of the transition portion 61 is less than 4d1, then the width d2 of the transition portion 61 is relatively small, and the width d2 of the transition portion 61 is close to the width d1 of the main body portion 62. Therefore, the widening design of the transition portion 61 is not ideal. If the width d2 of the transition portion 61 is greater than 8d1, then the width d2 of the transition portion 61 is relatively large, and the difference between the width d2 of the transition portion 61 and the width d1 of the main body portion 62 is significant. This can easily lead to stress concentration and breakage of the second metal line 60 at the main body portion 62 and the transition portion 61. Therefore, the width d2 of the transition portion 61 can be 4d1≤d2≤8d1. This widening design of the transition portion 61 is more effective and can prevent stress concentration and breakage of the second metal line 60 at the main body portion 62 and the transition portion 61.

[0053] Furthermore, the width d2 of the transition portion 61 can be 4d1, 4.5d1, 5d1, 5.5d1, 6d1, 6.5d1, 7d1, 7.5d1, or 8d1, and this embodiment does not impose a specific limitation on it.

[0054] For example, the second metal line 60 is formed by PDS (Printed Direct Structuring). This PDS forming method allows the second metal line 60 to be formed simultaneously from the fourth metal part 44 and the middle frame 10, which are not known to each other, thus reducing the forming difficulty. Furthermore, compared to LDS forming, the second metal line 60 formed by PDS has higher strength and is less prone to deformation.

[0055] Optionally, the thickness of the middle frame 10 is t, where 0.8mm ≤ t ≤ 1.5mm. If the thickness t of the middle frame 10 is less than 0.8mm, then the thickness t of the middle frame 10 is relatively small, resulting in lower overall structural strength. If the thickness t of the middle frame 10 is greater than 1.5mm, then the thickness t of the middle frame 10 is relatively large, which is detrimental to the slim and lightweight design of the smart host 100. Therefore, the thickness t of the middle frame 10 can be 0.8mm ≤ t ≤ 1.5mm, resulting in higher overall structural strength and facilitating the slim and lightweight design of the smart host 100.

[0056] Furthermore, since the second metal line 60 is formed using PDS, the second metal line 60 has high strength, so the middle frame 10, which serves as a carrier for part of the second metal line 60, can have a thinner thickness, for example, reduced to less than 1 mm.

[0057] This utility model provides a smart host 100. A circuit board 20 is installed within a mid-frame 10, and a bracket 30 is located on the upper surface of the mid-frame 10. A first metal circuit is formed on the surface of the bracket 30 and configured as a first antenna. The first metal circuit is electrically connected to the circuit board 20 to achieve communication between the first antenna and the circuit board 20. Thus, when the first antenna needs to be rebuilt after debugging, the bracket 30 can be reset separately, reducing the difficulty of resetting the first antenna and thereby reducing modification costs.

The smart wearable device 200 includes a wearable component 201 and a smart host 100 in Embodiment 1. The wearable component 201 is connected to the smart host 100.

[0060] Embodiment 2 of this utility model provides a smart wearable device 200 with a lower difficulty in antenna debugging and a lower debugging and modification cost.
