Abstract
Description
Technical Field
[0001] This utility model relates to the field of wearable device technology, and in particular to an antenna structure for a wearable device and a wearable device. Background Technology
[0002] Currently, in the smartwatch market, the metallic appearance and texture are highly favored by users. However, with the continuous increase in frequency bands, the pursuit of ultimate design, and the diversification and complexity of functions, antenna space is gradually deteriorating, interference is becoming increasingly difficult to handle, and signal quality is hard to guarantee effectively. A signal testing survey conducted by a consumer association in a certain city in 2019 exposed signal problems in many brands. Signal quality not only determines communication quality but is also closely related to power consumption and standby time, which is one of the core pain points for users today.
[0003] Currently, the mainstream antenna technologies used in smartwatches are LDS (Light Diode) and FPC (Flexible Printed Circuit) antennas. Both basically use spring clips as a connection structure to connect to the antenna. The difference is that LDS antennas require a decorative cover to cover the outside of the antenna for aesthetic purposes, while FPC antennas need to be made on the inner wall of the casing.
[0004] Due to the dark color of LDS (Light Diode) technology, even with five coats and five bakes of paint, it's difficult to achieve a good appearance. Therefore, an additional decorative layer is usually needed to cover the antenna, which both worsens the antenna space and limits the ID (integrated design) appearance. FPC (Fiberboard Printed Circuit) technology has many limitations in its wiring structure, greatly restricting antenna performance. Overall, both current mainstream technologies sacrifice antenna performance and increase the difficulty of structural design. Utility Model Content
[0005] This utility model provides an antenna structure for a wearable device and a wearable device in general, which can reduce the difficulty of antenna structure design and increase the antenna arrangement space in order to enhance antenna performance.
[0006] In a first aspect, this utility model provides an antenna structure for a wearable device, comprising: a transparent antenna and a housing;
[0007] The transparent antenna includes a first antenna and a second antenna, which are respectively fixed on both sides of the housing;
[0008] The housing edge is provided with a first through hole and a second through hole. The first antenna is connected to a first gold finger on the inside of the housing through the first through hole and is connected to a first antenna spring on the motherboard of the wearable device through the first gold finger. The second antenna is connected to a second gold finger on the inside of the housing through the second through hole and is connected to a second antenna spring on the motherboard of the wearable device.
[0009] Optionally, the transparent antenna is a transparent metal film layer.
[0010] Optionally, the thickness of the transparent antenna is 0.05mm to 0.1mm.
[0011] Optionally, the transparent antenna is fixed to the housing by a thermo-pressing process.
[0012] Optionally, the transparent antenna is fixed to the housing by an adhesive dispensing process.
[0013] Optionally, the antenna structure further includes a grounding spring for connecting to the grounding post of the motherboard.
[0014] Optionally, the grounding spring includes a first grounding spring and a second grounding spring.
[0015] Optionally, the housing is made of engineering plastic.
[0016] Optionally, the housing is integrally molded.
[0017] Secondly, this utility model embodiment also provides a wearable device, including the antenna structure of the wearable device as described in the first aspect.
[0018] The antenna structure for a wearable device provided in this embodiment includes a transparent antenna and a housing. The transparent antenna includes a first antenna and a second antenna, which are respectively fixed to both sides of the housing. The housing edge has a first through hole and a second through hole. The first antenna connects to a first gold finger inside the housing through the first through hole and to a first antenna spring on the wearable device's motherboard through the first gold finger. The second antenna connects to a second gold finger inside the housing through the second through hole, and the second gold finger connects to a second antenna spring on the wearable device's motherboard. By combining this with the specific structure of the wearable device and using a transparent antenna, its transparency does not affect the original color of the housing, thus eliminating the need for thicker decorative parts. Furthermore, when different colors are required, the appearance can be optimized through painting. Reducing the number of decorative parts provides more space for the transparent antenna, enhancing antenna performance and reducing the requirements and costs associated with product structure design.

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0021] Figure 2 This is a schematic diagram of the antenna structure of a wearable device provided in an embodiment of the present invention. Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] In the description of this utility model, unless otherwise explicitly specified and limited, the positional relationships described by the terms up, down, left, right, etc., refer to the direction when the image is facing the user, that is, the direction of up, down, left, right, etc., with the page as the plane when the image is displayed normally.
[0024] Figure 1 An exemplary diagram illustrates the structure of an antenna structure for a wearable device provided by this utility model. The antenna structure may include a transparent antenna 100 and a housing 200. The transparent antenna 100 is laid on the outside of the housing 200, serving as the outer surface of the housing 200.
[0025] The transparent antenna 100 is typically a transparent metal film layer, which is a transparent conductive film that can conduct electricity. It enables the design of the transparent antenna 100, is easy to install, and has properties such as waterproof, pollution-proof, and UV-proof. It does not affect signal transmission or communication performance.
[0026] like Figure 2 As shown, the transparent antenna 100 includes a first antenna 110 and a second antenna 120, which are respectively fixed to both sides of the housing 200. The housing 200 has a first through hole and a second through hole (not shown in the figure) on its edge. The first antenna 110 connects to a first gold finger inside the housing through the first through hole and to a first antenna spring on the motherboard of the wearable device through the first gold finger. The second antenna 120 connects to a second gold finger inside the housing 200 through the second through hole, and the second gold finger connects to a second antenna spring on the motherboard of the wearable device. Furthermore, the antenna structure also includes a grounding spring for connecting to the grounding post of the motherboard. The grounding spring includes a first grounding spring and a second grounding spring.
[0027] like Figure 2As shown, the first antenna 110 can be a main antenna, and the second antenna 120 is a three-in-one antenna. The main antenna includes a first antenna arm 111, a second antenna arm 112, and a third antenna arm 113. The first antenna arm 111 can be an intermediate frequency antenna arm, the second antenna arm 112 can be a high frequency antenna arm, and the third antenna arm 113 can be a low frequency antenna arm. That is to say, the main antenna can be an LTE main antenna, and the three-in-one antenna can be a combined GPS antenna, BT antenna, and WIFI antenna.
[0028] In the specific implementation process, the antenna wiring shape is first designed, and then the transparent antenna 100 film material is manufactured according to the shape drawing. Specifically, a metal mesh conductor layer is manufactured according to the drawing, and then a film is applied to the metal mesh conductor layer. The shape of this film is the same as the outer surface of the housing 200, that is, it needs to cover the outer surface of the housing 200.
[0029] To increase the space for antenna placement and avoid the impact of thickness differences on appearance, the thickness of the transparent antenna 100 can be 0.05mm to 0.1mm.
[0030] Once the transparent antenna 100 is manufactured, it can be fixed to the housing 200 using a hot-pressing process. Compared to traditional LDS antennas that require direct laser forming, this transparent antenna 100 is colorless and can directly display the exterior of the housing 200, eliminating the need for decorative parts or dark paint on the exterior of the housing 200.
[0031] In addition, the transparent antenna 100 can also be fixed to the housing 200 using conventional processes, namely by applying adhesive to the housing 200.
[0032] The aforementioned shell 200 is made of engineering plastic, such as polycarbonate (PC). This material has excellent performance, good mechanical properties, high strength, and impact resistance, and can withstand daily impacts; it has a certain degree of flame retardancy (some can meet the requirements of halogen-free flame retardancy), ensuring safe use; it is easy to process and mold, and can be made into various appearances, with relatively low cost.
[0033] The housing 200 adopts a one-piece molding design, which can save on manufacturing processes.
[0034] Based on the same technical concept, this utility model embodiment also provides a wearable device, including the antenna structure described in the above embodiments.
[0035] Based on the above embodiments, the antenna structure of the wearable device provided by this utility model includes: a transparent antenna and a housing; the transparent antenna includes a first antenna and a second antenna, which are respectively fixed on both sides of the housing; the edge of the housing is provided with a first through hole and a second through hole, the first antenna is connected to a first gold finger on the inner side of the housing through the first through hole, and is connected to a first antenna spring on the motherboard of the wearable device through the first gold finger, and the second antenna is connected to a second gold finger on the inner side of the housing through the second through hole, and the second gold finger is connected to a second antenna spring on the motherboard of the wearable device. By combining the specific structure of the wearable device and using a transparent antenna, due to its transparent characteristics, it does not affect the original color of the housing, thus eliminating the need for thicker exterior decorative parts, and the appearance color can be optimized through a painting process when different colors are required. By reducing the exterior decorative parts, more space is provided for the transparent antenna, enhancing antenna performance, while reducing the requirements and costs for product structure design.

Therefore, the appended claims are intended to be interpreted as including the alternative embodiments as well as all changes and modifications falling within the scope of the present invention.
[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope.
