Description

Technical Field

[0001] This utility model relates to the field of smartwatch technology, and in particular to a metal frame antenna structure for a smartwatch. Background Technology

[0002] In today's rapidly developing digital age, smart wearable devices such as smartwatches have become deeply integrated into people's daily lives, serving as versatile personal assistants that integrate health monitoring, information interaction, and convenient payment. As the functions of smartwatches become increasingly complex, their reliance on wireless communication becomes more pronounced, making stable and efficient signal transmission a key performance indicator.

[0003] Currently, most smartwatches with GPS positioning functions on the market use a built-in antenna structure. Because smartwatches themselves are small, while the motherboard with the GPS positioning module is relatively large, the GPS signal of models made with the conventional built-in antenna structure is not ideal. This results in weak GPS signal and inaccurate positioning when the smartwatch is used in actual use, which seriously affects the user experience.

[0004] In particular, some smartwatches have large metal decorative parts on their cases to enhance their appearance and decoration. However, these metal decorative parts can seriously interfere with the normal wireless signal transmission and reception of the built-in antenna structure, thereby further reducing the stability and effectiveness of the smartwatch's GPS signal reception and resulting in poorer positioning accuracy.

[0005] Therefore, we propose a metal frame antenna structure for smartwatches. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies. In order to enhance the appearance and decoration of smartwatches, large areas of metal decorative parts are provided on their watch cases. However, these metal decorative parts, in turn, severely interfere with the normal wireless signal transmission and reception of the built-in antenna structure, thereby further reducing the stability and effectiveness of the smartwatch's GPS signal reception and resulting in even worse positioning accuracy.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A metal frame antenna structure for a smartwatch includes a housing structure, the housing structure including a metal frame shell, the top of the metal frame shell having a plurality of signal transmission through holes, the right side of the plurality of signal transmission through holes having a rotating groove, and the right side of the rotating groove having a locking groove.

[0009] The outer shell structure is equipped with a control motherboard, and an antenna module is provided at the connection point of the control motherboard and at several signal transmission through holes.

[0010] The housing structure also has a sealing structure inside, which is used to seal the metal frame housing of the display screen when no signal expansion is required. The sealing structure includes a sealing plate with two plug-in fixing rods on the sealing plate.

[0011] The sealing structure is provided with a locking structure at the connection point. The locking structure is used to lock the sealing structure when it is sealing to prevent accidental activation. The locking structure includes a locking rack. The locking rack has grooves on both the front and back sidewalls. The bottom of the locking rack has several rack bodies. The connection point of the rack bodies is provided with a fixing member. The fixing member has several supporting sliders inside. The connection point of the rack bodies is also provided with a gear. The back side of the gear is also equipped with a rotating rod. The back side of the rotating rod is provided with a turning cap. The connection point of the turning cap is provided with a locking plate. The locking plate has a locking rod inside.

[0012] As a preferred embodiment of this utility model, the sealing plate and the two plug-in fixing rods are designed as an integral unit, and the outer sides of the two plug-in fixing rods are connected with sealing gaskets and inserted into the two signal transmission through holes of the metal frame housing.

[0013] As a preferred embodiment of this utility model, each of the two plug-in fixing rods is provided with a connecting groove, and the two connecting grooves are used to form a connection with the locking rack, thereby engaging with each other to form a limit.

[0014] As a preferred embodiment of this utility model, the locking rack can be slidably connected to the support slider of the fixing member through the sliding groove, and the fixing member is fixedly connected to the metal frame shell, thereby realizing the support and limiting of the locking rack.

[0015] As a preferred embodiment of this utility model, the gear meshes with the rack body. When the screw cap rotates, it drives the gear to rotate through the rotating rod, thereby driving the locking rack to move and insert into the connecting groove of the insertion fixing rod.

[0016] As a preferred embodiment of this utility model, the locking plate is fixedly connected to the rotating cap, and the locking rod can pass through the locking plate and the locking groove of the metal frame housing to connect, thereby locking the rotating cap and preventing accidental activation.

[0017] As a preferred embodiment of this utility model, the antenna module is electrically connected to the control motherboard via a cable.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] In this invention, several signal transmission through holes are carefully arranged on the metal frame housing, which opens up a dedicated channel for signal interaction between the antenna module and the outside world, effectively reducing the shielding and interference of metal decorative parts on the signal and ensuring smooth transmission and reception of wireless signals.

[0020] The sealing plate in the sealed structure is integrated with two plug-in fixing rods with sealing gaskets. When signal expansion is not required, the sealing plate can fit tightly against the metal frame housing, the plug-in fixing rods can be accurately inserted into the signal transmission through hole, and the sealing gaskets can effectively fill the gaps, keeping out external impurities such as moisture and dust, which greatly extends the service life of the internal electronic components.

[0021] When sealing is required, rotate the screw cap, which drives the gear to rotate through the rotating rod. The meshing action of the gear and the rack body causes the locking rack to slide smoothly along the support slider of the fixing part in the slide groove, and finally insert into the connecting groove of the insertion fixing rod to achieve a firm lock of the sealing plate. The operation is simple and intuitive.

[0022] The locking plate is fixedly connected to the screw cap, and the locking rod passes through the locking plate and is inserted into the locking groove of the metal frame housing. The double locking mechanism effectively prevents accidental activation and avoids seal failure due to accidental collision. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] like Figure 1-5 As shown, this utility model provides a technical solution: First, a suitable metal material is selected to make the metal frame housing 1. This material must have good conductivity to meet the antenna function requirements, and also have sufficient mechanical strength to ensure the overall durability of the watch.

[0034] Display screen 2 is used to display information from the smartwatch.

[0035] On the top of the metal frame housing 1, based on the signal radiation characteristics of the antenna module 31 and the internal layout of the watch, several signal transmission through holes 4 are precisely machined. The aperture, spacing and position of these through holes have been strictly designed and optimized to ensure the high efficiency of signal transmission.

[0036] Next, on the right side of the signal transmission through hole 4, a rotating groove 5 is formed using a precision mold forming process. The size of the rotating groove 5 is adapted to the screw cap 16 to be installed later, ensuring that the screw cap 16 can rotate smoothly in it. On the right side of the rotating groove 5, a customized locking groove 6 is also formed using a high-precision process to cooperate with the locking rod 18 to achieve a sealing and locking function.

[0037] The control motherboard 3 is connected to the antenna module 31:

[0038] The control motherboard 3 is carefully installed in a designated location inside the casing structure, ensuring a reasonable layout of its connection lines with other electronic components inside the watch to avoid tangling or interference. A carefully designed antenna module 31 is installed at the connection point between the control motherboard 3 and the signal transmission via 4. The antenna module 31 employs advanced microstrip antenna technology or other suitable miniaturized antenna designs to fit the limited internal space of the smartwatch.

[0039] The antenna module 31 is securely connected to the control motherboard 3 using high-quality, low-loss cables. The connection points are welded and sealed with sealant to prevent oxidation or loosening of the solder joints, thus ensuring the stability and reliability of signal transmission.

[0040] Sealing structure fabrication and installation:

[0041] The sealing plate 7 and two plug-in fixing rods 8 are manufactured using an integral injection molding process to ensure the firmness and integrity of the connection between the two. High-performance sealing gaskets are tightly attached to the outside of the two plug-in fixing rods 8. The sealing gaskets are made of wear-resistant, corrosion-resistant and highly elastic rubber material, which can not only ensure the sealing effect, but also maintain the sealing performance after multiple insertions and removals.

[0042] When installing the sealing structure onto the metal frame housing 1, precisely align the two plug-in fixing rods 8 with the signal transmission through hole 4 and insert them smoothly until the sealing plate 7 is tightly fitted to the metal frame housing 1. At this point, the sealing gasket fully fills the gaps around the through hole, forming a preliminary sealing state.

[0043] Locking structure assembly:

[0044] For the locking rack 9, a sliding groove 10 is first opened on its front and back side walls by precision milling. The surface of the sliding groove 10 is polished to reduce the coefficient of friction and ensure that the locking rack 9 can move smoothly. At the bottom of the locking rack 9, several rack bodies 11 are integrally formed. The tooth profile accuracy of the rack body 11 is strictly controlled to ensure perfect meshing with the gear 14.

[0045] The fastener 12 is installed at the corresponding position of the metal frame housing 1. Multiple support sliders 13 are pre-embedded inside the fastener 12. The support sliders 13 are made of plastic with a low coefficient of friction to provide stable support for the sliding of the locking rack 9. The gear 14 is installed at the connection of the rack body 11. The shaft of the gear 14 is connected to the rotating rod 15 by a key or fixed with a set screw to ensure the reliability of power transmission. The rotating rod 15 extends through the metal frame housing 1 to the rotating groove 5. The rotating cap 16 is firmly installed at its end. The surface of the rotating cap 16 is designed with anti-slip texture for easy operation. Finally, the locking plate 17 is fixedly connected to the rotating cap 16, and the locking rod 18 is installed inside the locking plate 17. The fit tolerance between the locking rod 18 and the locking groove 6 is controlled within a very small range to ensure the accuracy of locking.

[0046] Workflow:

[0047] In the daily wear state (sealed state), when the smartwatch is in a daily wear scenario and no signal expansion is required, the sealing structure is in a sealed state. At this time, the sealing plate 7 is tightly attached to the metal frame shell 1, the two plug-in fixing rods 8 are inserted into the signal transmission through hole 4, the sealing gasket effectively prevents moisture and dust from entering, and the locking rack 9 is supported by the fixing part 12 and is kept stable by the slide groove 10. Its rack body 11 is tightly meshed with the gear 14.

[0048] The locking lever 18 passes through the locking plate 17 and is inserted into the locking groove 6 of the metal frame housing 1, which firmly locks the screw cap 16, preventing the sealing structure from loosening due to accidental events such as wrist shaking or collisions. Users do not need to worry about external impurities damaging the internal electronic components, and the internal electronic components of the watch operate stably in a dry and clean environment.

[0049] Signal extension requirement state (unsealed): When the user is in an area with weak signal, such as a basement, remote mountainous area or dense high-rise building area, and needs to enhance the signal reception capability of the smartwatch, the operation is as follows: First, the user manually holds the screw cap 16 and rotates it counterclockwise (or according to the designed unlocking direction). The screw cap 16 drives the rotating rod 15 to rotate, and the rotating rod 15 in turn drives the gear 14 to rotate.

[0050] Due to the meshing action between gear 14 and rack body 11, locking rack 9 slides along the support slider 13 of fixing member 12 in the groove 10 away from the plug-in fixing rod 8 until locking rack 9 disengages from the connecting groove of plug-in fixing rod 8, releasing the limitation on plug-in fixing rod 8. At this time, the user can gently pull out the two plug-in fixing rods 8, open the sealing plate 7, and fully expose the signal transmission through hole 4. The antenna module 31 can perform efficient signal interaction with the external environment, improve the wireless signal transmission and reception capability of smartwatch, and ensure the stable operation of functions such as GPS navigation and Bluetooth data transmission.

[0051] To restore the sealing state, when the user leaves the area with weak signal and returns to the normal environment, and needs to restore the watch's sealing state to protect the internal components, the sealing plate 7 is realigned with the metal frame housing 1, and the two plug-in fixing rods 8 are inserted into the signal transmission through hole 4.

[0052] Then, rotate the screw cap 16 clockwise. Rotating the screw cap 16 causes the rotating rod 15 and gear 14 to rotate. The gear 14 drives the locking rack 9 to slide along the slide groove 10 towards the insertion fixing rod 8. Finally, the locking rack 9 is inserted into the connecting groove of the insertion fixing rod 8, thereby limiting the insertion fixing rod 8 again. At the same time, the locking rod 18 is reinserted into the locking groove 6 as the screw cap 16 rotates, completing the double locking and ensuring that the sealing structure is stable and reliable. The smartwatch is restored to its daily waterproof and dustproof sealed state.

[0053] 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.
