Description

Technical Field

[0001] This invention relates to the field of watch technology, specifically to a retractable antenna cavity structure for smartwatches. Background Technology

[0002] With the rapid development of electronic technology, smartwatches have gradually entered people's homes. Compared with traditional watches, smartwatches can not only display the time, but also realize communication, Internet access and other functions, which improves the versatility of watches. The antenna is the core partner for realizing these functions, supporting its key capabilities such as communication, positioning and data transmission. To fit the compact body of the watch, the antenna often adopts a miniaturized design, such as built-in ceramic antenna, flexible PCB antenna, or conformal antenna integrated with the metal case and strap, so as to achieve efficient transmission and reception of multi-band signals such as Bluetooth, Wi-Fi, GPS, and cellular networks in millimeter-level space, becoming a smart node that can seamlessly connect to the Internet of Things.

[0003] The existing publication number CN207852925U discloses a watch device and a watch, the main purpose of which is to improve the transmission and reception effect of the antenna signal of the watch device. The main technical solution of this utility model is as follows: a watch device, including: a watch case, an antenna module and a connecting spring, the watch case is made of metal, the connecting spring is disposed inside the watch case, one end of the connecting spring is connected to the antenna module, and the other end abuts against the inner wall of the watch case under the action of elasticity, the antenna module is used to electrically connect with the watch case through the connecting spring, so that the watch case serves as the antenna radiator of the antenna module, wherein the connecting spring is made of metal.

[0004] However, in the aforementioned metal-cased watch antenna design, space constraints lead to insufficient multi-band signal performance, and the static structure is difficult to adapt to dynamic scene requirements. Specifically, in traditional designs, although the metal casing can act as a radiator, the physical size of the built-in antenna is fixed due to the compact space of the watch. In high-frequency bands, such as cellular networks and UWB, the signal gain and stability are insufficient, resulting in the static design being unable to meet the performance requirements of different scenarios. Utility Model Content

[0005] The purpose of this invention is to provide a retractable antenna cavity structure for smartwatches, in order to solve the problem that static structures in traditional metal-cased watch antenna designs are difficult to adapt to dynamic scene requirements.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A smartwatch retractable antenna cavity structure includes a watch body, a rotating cover coaxially rotatably connected to the top surface of the watch body, a liftable lifting base movably connected inside the watch body, a ceramic antenna module mounted on the top of the lifting base, a probe hole for the ceramic antenna module to extend from the surface of the rotating cover, a guide block fixedly connected to the surface of the lifting base, a spring fixedly connected between the guide block and the watch body, and an arc-shaped inclined wall that limits the movement of the guide block on the bottom surface of the rotating cover, the highest point of the arc-shaped inclined wall communicating with the probe hole.

[0008] Preferably, an L-shaped slip ring is fixedly connected to the bottom end of the rotating cover, and an annular groove for the L-shaped slip ring to rotate is provided on the surface of the watch body.

[0009] Preferably, the bottom of the rotating cover is provided with a clearance groove, which provides space for the lifting base and the ceramic antenna module to rise.

[0010] Preferably, the surface of the watch body is provided with a lifting groove for the lifting seat to move up and down.

[0011] Preferably, a cushioning pad is installed on the top of the lifting seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By extending the antenna module when needed, the effective radiation length and volume of the antenna are dynamically expanded, significantly improving the transmission and reception efficiency of high-frequency signals, especially enhancing signal strength in scenarios such as 5G communication and precise positioning;

[0014] 2. Through a scalable mechanism, the antenna shape can be automatically adjusted according to actual usage scenarios, such as weak signal environments outdoors and high-speed data transmission. While ensuring the watch's slim and lightweight appearance, it solves the pain point that static design cannot meet the performance requirements of different scenarios, and achieves a dynamic balance between antenna performance, power consumption and appearance design.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 7 This utility model provides a technical solution.

[0025] The smartwatch features a retractable antenna cavity structure, including a watch body 1. A rotating cover 4 is coaxially rotatably connected to the top surface of the watch body 1. A liftable base 6 is movably connected inside the watch body 1. A ceramic antenna module 9 is mounted on the top of the liftable base 6. A probe hole 5 is provided on the surface of the rotating cover 4 for the ceramic antenna module 9 to extend. A guide block 7 is fixedly connected to the surface of the liftable base 6. A spring 8 is fixedly connected between the guide block 7 and the watch body 1. An arc-shaped inclined wall 10 is provided on the bottom surface of the rotating cover 4 to limit the guide block 7. The highest point of the arc-shaped inclined wall 10 is connected to the probe hole 5. In the initial state, when the guide block 7... Located in the area of ​​the non-arc inclined wall 10 on the bottom surface of the rotating cover 4, the rotating cover 4 presses down on the guide block 7, restricting the guide block 7 from rising, and causing the spring 8 to store elastic potential energy. The ceramic antenna module 9 is hidden inside the watch body 1. When the rotating cover 4 is rotated until the guide block 7 is aligned with the arc inclined wall 10, the arc surface of the arc inclined wall 10 provides upward space for the guide block 7. The spring 8 releases potential energy to push the lifting seat 6 to rise until the guide block 7 reaches the highest point of the arc inclined wall 10. At this time, the ceramic antenna module 9 extends out from the probe hole 5 along with the lifting seat 6. The linkage design between the arc inclined wall 10 and the probe hole 5 ensures that the antenna remains stably extended.

[0026] An L-shaped slip ring 3 is fixedly connected to the bottom of the rotating cover 4, and an annular groove 2 for the L-shaped slip ring 3 to rotate is provided on the surface of the watch body 1.

[0027] The bottom of the rotating cover 4 is provided with a clearance groove 11, which is used to provide space for the lifting base 6 and the ceramic antenna module 9 to rise.

[0028] The surface of the body 1 is provided with a lifting groove for the lifting seat 6 to rise and fall. By setting the lifting groove, the lifting seat 6 can be raised and lowered vertically in a stable manner.

[0029] A buffer pad is installed on the top of the lifting seat 6, which helps to cushion the movement when the lifting seat 6 rises and comes into contact with the rotating cover 4.

[0030] If necessary, a sealing plug can be inserted and removed into the probe hole 5 to seal the probe hole 5 in the initial state.

[0031] Specifically, in the initial state, the lifting seat 6 inside the watch body 1 is at its lowest position, and the ceramic antenna module 9 installed on the top is completely hidden inside the watch body 1 and does not protrude from the probe hole 5 on the surface of the rotating cover 4. The guide block 7 on the surface of the lifting seat 6 is located in the non-arc inclined wall 10 area on the bottom surface of the rotating cover 4. At this time, the rotating cover 4 presses the guide block 7 with its own bottom surface, so that the spring 8 connected between the guide block 7 and the watch body 1 is compressed and stores elastic potential energy.

[0032] The L-shaped slip ring 3 at the bottom of the rotating cover 4 engages with the annular groove 2 on the surface of the watch body 1, so that the rotating cover 4 is stably coaxially mounted on the top surface of the watch body 1 and is in the initial non-rotating state.

[0033] During the extension operation of the ceramic antenna module 9, the user holds the rotating cover 4 and applies rotational force to make it rotate coaxially around the top surface of the watch body 1. The L-shaped slip ring 3 at the bottom of the rotating cover 4 rotates within the annular groove 2 of the watch body 1. As the rotating cover 4 rotates, the arc-shaped inclined wall 10 on its bottom surface gradually rotates to a position aligned with the guide block 7. When the guide block 7 is within the arc-shaped inclined wall 10, the arc-shaped surface of the arc-shaped inclined wall 10 provides upward space for the guide block 7, no longer restricting the vertical movement of the guide block 7. When the rotating cover 4 continues to rotate, the guide block 7 will be pushed upward by the elastic force of the spring 8, pushing the lifting seat 6 to move upward. The ceramic antenna module 9 on the top of the lifting seat 6 rises along with it. The ceramic antenna module 9 extends and stably keeps the lifting seat 6 rising until the guide block 7 reaches the highest point of the arc-shaped inclined wall 10. At this time, the ceramic antenna module 9 extends out from the probe hole 5 on the surface of the rotating cover 4, completing the extension action.

[0034] The clearance groove 11 at the bottom of the rotating cover 4 provides ample longitudinal movement space for the lifting seat 6 and the ceramic antenna module 9 to rise, avoiding obstruction during the rising process.

[0035] Antenna retraction operation process: Reverse operation, the user rotates the rotating cover 4 again, making it rotate in the opposite direction of the initial state. The arc-shaped inclined wall 10 gradually misaligns with the guide block 7. The guide block 7 moves from the highest point of the arc-shaped inclined wall 10 to the non-arc-shaped inclined wall 10 area on the bottom surface of the rotating cover 4. When the guide block 7 moves to the non-arc-shaped inclined wall 10 area on the bottom surface of the rotating cover 4, the rotating cover 4 forces the lifting seat 6 to move downward. The ceramic antenna module 9 descends with the lifting seat 6 and gradually retracts from the probe hole 5 into the inside of the watch body 1.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
