[0001] The present application relates to the technical field of smart watches, and particularly to a gap antenna structure for a smart watch and a smart watch. Background Art

[0002] At present, the outer frame and the inner frame on the mainstream titanium alloy smart watches in the market are integrally formed by injection molding through NMT technology. The inner frame extends beyond the outer frame and together forms the appearance of the smart watch. A gap antenna is formed at the inner frame that extends beyond the outer frame to emit electromagnetic wave signals to the outside. After molding, a PVD coating process is also used on the surfaces of the outer frame and the inner frame to improve the appearance of the smart watch.

[0003] However, during the coating process, the surface of the gap antenna reserved on the inner frame is also covered by the coating layer and will conduct electricity with the shell metal, thereby affecting the antenna emission effect. Therefore, an additional 3D laser engraving process is required to remove the coating layer on the surface of the gap antenna, which is a complex process and increases the manufacturing cost.

[0026] In order to be able to more clearly understand the above-mentioned objects, features, and advantages of this application, the following will further describe the solutions of this application. It should be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other.

[0027] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Obviously, the embodiments in the specification are only a part of the embodiments of the present application, rather than all of the embodiments.

[0028] The following provides a detailed description of the smart watch slot antenna structure and the smart watch through specific embodiments:

[0029] Referring to Figures 1 to 4 As shown, a smart watch slot antenna structure provided by some embodiments of the present invention includes a middle frame and a decorative ring 3.

[0030] Among them, the middle frame includes an outer frame 1 and an inner frame 2. The outer frame 1 is sleeved on the outside of the inner frame 2. The inner frame 2 can transmit electromagnetic wave signals. The top of the inner frame 2 exceeds the top of the outer frame 1, and a slot antenna 21 is formed in the part where the inner frame 2 exceeds the outer frame 1 to transmit electromagnetic wave signals to the outside through the slot antenna 21. The decorative ring 3 is arranged on the top of the outer frame 1 and is sleeved on the outside of the slot antenna 21.

[0031] In specific implementation, the decorative ring 3 has a good appearance. When the decorative ring 3 is arranged on the outside of the slot antenna 21, with the cooperation of the decorative ring 3, only processes such as coating on the surface of the outer frame 1 can ensure that the smart watch has high appearance performance, without coating the surface of the inner frame 2, which can avoid covering the surface of the slot antenna 21 with a coating layer. Furthermore, it can ensure good emission effect of the slot antenna 21, and also avoid the process of removing the coating layer on the surface of the slot antenna 21 by laser engraving, reduce the processing procedures, and improve the manufacturing efficiency.

[0032] In some embodiments, referring to Figure 2 and Figure 3 As shown, the top surface of the decorative ring 3 is lower than the top surface of the inner frame 2 to form a receiving space 4 for receiving the bezel between the top surface of the decorative ring 3 and the top surface of the inner frame 2. The area of the inner frame 2 corresponding to the decorative ring 3 is formed as the slot antenna 21.

[0033] That is to say, the bezel is sleeved on the outside of the top surface of the inner frame 2. The decorative ring 3 is arranged between the bottom surface of the bezel and the top surface of the outer frame 1. The inner frame 2 located between the bottom surface of the bezel and the top surface of the outer frame 1 is formed as the slot antenna 21. The outer frame 1, the decorative ring 3 and the bezel together form a complete surface, and then the slot antenna 21 can be enclosed inside the above complete surface. Furthermore, the appearance performance of the smart watch is ensured through the outer frame 1, the decorative ring 3 and the bezel, without coating the inner frame 2, and avoiding covering the surface of the slot antenna 21 with a coating layer.

[0034] In specific implementation, the part of the inner frame 2 that extends beyond the top of the outer frame 1 is recessed towards the inner side of the inner frame 2 to form an installation space, and the decorative ring 3 is arranged in the installation space. It can be understood that the part of the inner frame 2 that extends beyond the top of the outer frame 1 is recessed relative to the outer side wall of the remaining part of the inner frame 2, thereby being able to provide a larger installation space for the decorative ring 3. Further, the outer side wall of the decorative ring 3 is recessed towards the inner side of the outer frame 1 relative to the outer side wall of the outer frame 1, avoiding protruding from the outer side of the outer frame 1, enabling a smoother transition in the appearance of the smart watch and preventing snagging on clothing or other accessories, etc.

[0035] Referring to Figure 3 As shown, the part of the inner frame 2 that extends beyond the top of the outer frame 1 has a first stepped surface 22 and a second stepped surface 23 that are angularly connected, and the first stepped surface 22 and the second stepped surface 23 jointly enclose the installation space. That is to say, the first stepped surface 22 and the second stepped surface 23 are formed by the recess of the part of the inner frame 2 that extends beyond the top of the outer frame 1. When the decorative ring 3 is installed in the installation space, the decorative ring 3 can cover the first stepped surface 22 and part of the second stepped surface 23, thereby eliminating the need for surface coating treatment on the first stepped surface 22 and part of the second stepped surface 23, and saving the subsequent laser engraving process on the surface of the slot antenna 21.

[0036] Specifically, the first stepped surface 22 is flush with the top surface of the outer frame 1, and the first stepped surface 22 and the top surface of the outer frame 1 jointly support the decorative ring 3. By the decorative ring 3, the junction between the first stepped surface 22 and the top surface of the outer frame 1 can be covered, ensuring the appearance performance of the smart watch. The decorative ring 3 is sleeved on the outside of the second stepped surface 23, and the area of the second stepped surface 23 corresponding to the decorative ring 3 forms the slot antenna 21, and the watch band is sleeved on the outside of the second stepped surface 23 outside the slot antenna 21.

[0037] It should be noted that the second stepped surface 23 is recessed towards the inner side of the inner frame 2 relative to the outer side wall of the inner frame 2, which can enable the electromagnetic wave signal to have a larger divergence angle, thereby improving the antenna emission effect.

[0038] In some embodiments, a snap structure is provided on the inner wall of the decorative ring 3, and a snap - fitting structure is provided on the outer wall of the slot antenna 21. The snap structure and the snap - fitting structure are snap - fitted, thereby fixing the device ring on the outside of the slot antenna 21, preventing the position of the decorative ring 3 from moving, and further preventing the inner frame 2 from being exposed, thus ensuring the appearance performance of the smart watch.

[0039] In specific implementation, the snap structure includes a rib integrally formed on the decorative ring 3, and the snap - fitting structure includes a slot. The rib is inserted into the slot. It can be understood that the rib protrudes from the inner wall surface of the decorative ring 3 and can thus be inserted into the slot. Through the insertion and cooperation of the rib and the slot, the decorative ring 3 can be prevented from rotating relative to the inner frame 2 and can also be prevented from detaching from the inner frame 2, ensuring stable installation and improving product quality control.

[0040] Specifically, both the number of the convex ribs and the number of the card slots are multiple. The multiple convex ribs are arranged on the inner wall of the decorative ring 3 at intervals in the circumferential direction, and the card slots are arranged in one-to-one correspondence with the buckles. That is to say, the multiple convex ribs are distributed at intervals on the inner side wall of the decorative ring 3, and the multiple card slots are distributed at intervals on the outer side wall of the inner frame 2. When the multiple convex ribs are matched with the multiple card slots one by one, the decorative ring 3 can be stably matched with the inner frame 2 at multiple positions, which can avoid excessive deformation and damage to the decorative ring 3.

[0041] Of course, it should be noted that the decorative ring 3 and the inner frame 2 can also be connected in other ways, which is not limited in this disclosure. As long as the relative displacement between the decorative ring 3 and the inner frame 2 can be restricted so that the decorative ring 3 can be stably matched with the inner frame 2.

[0042] In some embodiments, the outer frame 1 is a metal outer frame with high strength and good wear resistance, and the inner frame 2 is a plastic inner frame. With such a setting, electromagnetic wave signals can be transmitted to the outside through the inner frame 2 and the slot antenna 21. The outer frame 1 and the inner frame 2 are injection-molded into an integral structure, which can avoid using additional connectors and make the structure stable.

[0043] Specifically, the hardness of the decorative ring 3 is greater than that of the inner frame 2. It can be understood that after the metal outer frame and the plastic inner frame are integrally formed, the inner frame 2 needs to be polished. During the polishing process, the polishing amount is uncontrollable and it is easy to grind the slot antenna 21 flat. When the hardness of the decorative ring 3 is greater than that of the inner frame 2, the decorative ring 3 can protect the inner frame 2, and thus can appropriately control the polishing amount, effectively avoiding the appearance impact on the slot antenna 21 during the polishing process, reducing the risk of the slot being ground flat, and improving the process yield. Specifically, when implemented, the decorative ring 3 can transmit electromagnetic wave signals to avoid shielding or interfering with the electromagnetic wave signals.

[0044] In some embodiments, the smart watch slot antenna structure further includes a coating layer, and the coating layer covers the surface of the outer frame 1 to jointly improve the appearance performance of the smart watch with the decorative ring 3. Specifically, the surface of the outer frame 1 can be coated by PVD physical vapor deposition technology.

[0045] Some other embodiments of the present application provide a smart watch, including a watch ring and the smart watch slot antenna structure as described in any of the above embodiments. The watch ring is sleeved on the outer side of the top of the inner frame 2, and the decorative ring 3 is supported between the outer frame 1 and the watch ring. The inner frame 2 located between the bottom of the watch ring and the top of the outer frame 1 forms the slot antenna 21, so as to jointly form a complete surface through the outer frame 1, the decorative ring 3 and the watch ring. The slot antenna 21 is enclosed inside the above complete surface, that is, the outer frame 1, the decorative ring 3 and the watch ring jointly form the appearance of the smart watch, which has a high aesthetic performance.

[0046] The smart watch provided by the embodiment of the present application includes the smart watch slot antenna structure of any of the above embodiments, and thus has the beneficial effects of the smart watch slot antenna structure of any of the above embodiments, which will not be elaborated herein.
