Description

Technical Field

[0001] This application belongs to the field of electronic product technology, specifically relating to a watch body and a watch. Background Technology

[0002] In related technologies, to achieve compact radio frequency design, smart wearable devices generally adopt a metal frame structure with integrated antennas. This structure requires injection molding of steel inserts into a plastic frame. One end of the steel insert is electrically connected to the metal frame through an antenna contact spring. The steel insert extends from the metal frame in a bent shape to the motherboard. The other end of the steel insert is connected to the motherboard through an antenna contact spring for power feeding, realizing a long-distance connection between the metal frame and the motherboard to achieve antenna power feeding.

[0003] However, in the quick-release watch body structure, due to the limited space occupied by the quick-release structure, it is impossible to electrically connect the metal frame to the motherboard at the location of the quick-release structure. This makes antenna feeding in the area where the quick-release structure is located a technical challenge, limiting the flexibility and performance of the radio frequency design. Summary of the Invention

[0004] The purpose of this application is to provide a watch body and a watch that can solve the problem of how to electrically connect the metal frame to the motherboard at the location of the quick-release structure without affecting the quick-release function.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a watch body, including a housing and a main board. The housing includes a plastic housing and a metal frame attached to at least a portion of the outer side of the plastic housing. The plastic housing forms a receiving cavity, and the main board is disposed within the receiving cavity.

[0007] A quick-release strap assembly is provided in each of the two opposite side walls of the plastic housing;

[0008] The watch body includes a through hole that passes through the metal frame, the watch strap quick-release assembly, and the plastic housing, and a first connector passes through the through hole;

[0009] An antenna radiator is formed on the metal frame, and the antenna radiator is electrically connected to the motherboard through the first connector.

[0010] Secondly, embodiments of this application provide a watch, a watch strap, and a watch body as described in the first aspect; the watch strap is provided with at least one snap-fit ​​portion, which is detachably connected to a watch strap quick-release assembly.

[0011] In this embodiment, the watch body includes a housing and a mainboard. The housing includes a plastic shell and a metal frame attached to at least a portion of the outer surface of the plastic shell. The plastic shell forms a receiving cavity, and the mainboard is disposed within the receiving cavity. A quick-release strap assembly is respectively disposed in two opposite sidewalls of the plastic shell. The watch body includes a through-hole penetrating the metal frame, the quick-release strap assembly, and the plastic shell, through which a first connector passes. An antenna radiator is formed on the metal frame, and the antenna radiator is electrically connected to the mainboard via the first connector. In this embodiment, a through-hole for electrical connection is established by drilling through the quick-release strap assembly and its surrounding structure in the area occupied by the quick-release strap assembly. This allows the metal frame to reliably connect to the mainboard even in the area where the quick-release strap assembly is located, improving the flexibility and performance of the radio frequency design.

[0019] Please refer to Figures 1 to 3 The present invention provides a watch body, including a housing 1 and a main board 2. The housing 1 includes a plastic housing 12 and a metal frame 11 attached to at least a portion of the outer side surface of the plastic housing 12. The plastic housing 12 forms a receiving cavity 120, and the main board 2 is disposed in the receiving cavity 120.

[0020] A quick-release strap assembly 3 is provided in each of the two opposite side walls of the plastic housing 12;

[0021] The watch body includes a through hole a through the metal frame 11, the watch strap quick release assembly 3 and the plastic housing 12, and a first connector 4 is inserted through the through hole a;

[0022] An antenna radiator is formed on the metal frame 11, and the antenna radiator is electrically connected to the main board 2 through the first connector 4.

[0023] In the above embodiment, by opening a through hole a on each of the two opposite sidewalls of the watch body, the through hole a passes through the metal frame 11, the watch strap quick-release assembly 3 and the plastic shell 12; and a first connector 4 is inserted in the through hole a, so that the first end of the first connector 4 is electrically connected to the metal frame 11 and the second end of the first connector 4 is electrically connected to the motherboard 2, thereby realizing the power supply connection between the metal frame 11 and the motherboard 2 at the watch strap quick-release position, which improves the flexibility and performance of the radio frequency design.

[0024] Alternatively, the metal frame 11 can be fixed to the outer side of the plastic housing 12 by adhesive, achieving a low-cost metal appearance solution.

[0025] In some embodiments of this application, a second connector 5 and a third connector 6 are also provided inside the receiving cavity 120;

[0026] The first end of the first connector 4 is electrically connected to the metal frame 11, and the second end of the first connector 4 is fixedly connected to the second connector 5.

[0027] The first end of the third connector 6 is electrically connected to the first connector 4, and the second end of the third connector 6 is electrically connected to the main board 2. The antenna radiator is electrically connected to the main board 2 through the first connector 4 and the third connector 6.

[0028] In this embodiment, through hole a penetrates the metal frame 11, the watchband quick-release assembly 3, and the plastic housing 12; a first connector 4 is provided in through hole a, so that the first end of the first connector 4 is electrically connected to the metal frame 11, and the second end of the first connector 4 is fixedly connected to the second connector 5 and the third connector 6 located in the receiving cavity 120; in this way, the third connector 6 can further extend the signal from the first connector 4 and connect it to the corresponding power supply interface on the motherboard 2, and the antenna radiator formed on the metal frame 11 is electrically connected to the motherboard 2 through the first connector 4 and the third connector 6, thereby realizing the power supply connection between the metal frame 11 and the motherboard 2 at the watchband quick-release position.

[0029] In some embodiments of this application, the watch strap quick-release assembly 3 includes: a main body component 31 and an elastic component 32; a mounting groove 121 is provided on the side wall of the plastic housing 12, the extension direction of the mounting groove 121 is a first direction and the groove opening of the mounting groove 121 is located at the bottom of the plastic housing 12; the main body component 31 and the elastic component 32 are movably received in the mounting groove 121, the elastic component 32 is disposed at the bottom of the mounting groove 121, one end of the main body component 31 abuts against the elastic component 32, and the other end of the main body component 31 is exposed at the groove opening of the mounting groove 121;

[0030] The main component 31 is provided with a first mounting hole 310, the first connector 4 passes through the first mounting hole 310, and the width of the first mounting hole 310 in the first direction is greater than the thickness of the first connector 4 in the first direction.

[0031] The main body component 31 is provided with a first locking part 311, a first mounting hole 310 and a second locking part 312 at intervals along the second direction. The first mounting hole 310 is disposed between the first locking part 311 and the second locking part 312. The second direction is perpendicular to the first direction.

[0032] When no external force is applied to the main body component 31, the first locking part 311 and the second locking part 312 move to the locking position under the elastic force of the elastic member 32, and the watch strap quick release assembly 3 enters the locking state; when an external force is applied to the main body component 31 toward the elastic member 32, the first locking part 311 and the second locking part 312 move to the unlocking position, and the watch strap quick release assembly 3 enters the unlocking state.

[0033] For example, such as Figure 3 In this structure, the plastic housing 12 is the main supporting structure inside the watch body, forming a receiving cavity 120, and having a mounting groove 121 formed on its side wall along a first direction. The receiving cavity 120 is used to accommodate components such as the motherboard 2. Figure 1 In the middle, the containment cavity 120 is the internal space where the motherboard 2 is located.

[0034] For example, such as Figure 1 In this design, the main component 31 is a pin that can reciprocate along a first direction. The main component 31 is housed in the mounting groove 121, with one end abutting against the elastic component 32 and the other end exposed at the opening of the mounting groove 121 for user pressing operation. The elastic component 32 can be a spring, located at the bottom of the mounting groove 121, providing elastic force to the main component 31 so that the main component 31 is locked when no external force is applied. The first locking part 311 and the second locking part 312 are provided on the main component 31 for locking engagement with the watch strap connection structure. The first mounting hole 310 is a through hole in the main component 31 for the first connector 4 to pass through.

[0035] In specific implementation, the opening of the mounting groove 121 is located at the bottom of the housing 1; one end of the elastic member 32 is fixedly connected to the bottom of the mounting groove 121, and one end of the main body member 31 extends into the mounting groove 121 and is connected to the other end of the elastic member 32. When the mounting groove 121 presses the main body member 31 inward, the main body member 31 moves in the direction toward the elastic member 32, the elastic member 32 is further compressed, the first locking part 311 and the second locking part 312 move to the unlocked position, and the watch strap quick release assembly 3 enters the unlocked state; after the external force applied to the main body member 31 is removed, under the elastic force of the elastic member 32, the main body member 31 moves in the direction away from the elastic member 32, the first locking part 311 and the second locking part 312 move to the locked position, and the watch strap quick release assembly 3 enters the locked state; wherein, when the watch strap quick release assembly 3 enters the unlocked state, the watch strap 7 is in a detachable state or an installable state; when the watch strap quick release assembly 3 enters the locked state, the watch strap 7 is locked and fixed to the watch body.

[0036] It should be noted that at the location of the quick-release strap assembly 3, since the main body 31 needs to move in the first direction to lock / unlock, this occupies space and may interfere with the antenna feed path. This embodiment of the application, by providing a through hole a and a first mounting hole 310, allows the first connector 4 to directly pass through the main body 31 of the quick-release strap assembly 3. Furthermore, the width of the first mounting hole 310 in the first direction is designed to be greater than the thickness of the first connector 4 in the first direction, allowing sufficient space for the main body 31 to move. Moreover, the first mounting hole 310 allows the first connector 4 to slide without directly compressing or pulling on it in the first direction. Thus, the first connector 4 can exist relatively fixedly, unaffected by the movement of the main body 31, thereby ensuring its structural integrity and the stability of the electrical connection.

[0037] In such Figures 1 to 3In the structure shown, under natural conditions without external force, the main body 31 abuts against the side of the first mounting hole 310 closest to the elastic member 32 due to the elastic force of the elastic member 32. When an external force is applied to the main body 31, the maximum travel of the main body 31 is the difference between the width of the first mounting hole 310 and the thickness of the first connector 4 in the first direction. That is, when the main body 31 moves to its farthest position in the mounting groove 121, the inner wall of the first mounting hole 310 on the side away from the elastic member 32 abuts against the first connector 4. Through this embodiment, the metal frame 11 can be electrically connected to the motherboard 2 at the quick-release position of the watch strap through the first connector 4, and the main body 31 can also be limited in the first direction through the first connector 4.

[0038] like Figure 2 and Figure 3 As shown, when the watch strap 7 and the watch body are in a locked connection state, the two latching parts 71 on the watch strap 7 are locked and fixed with the first locking part 311 and the second locking part 312 respectively. The latching parts 71 are confined within the mounting groove 121 formed by the plastic housing 12, and the watch strap 7 is locked and fixed to the watch body. When the main body component 31 is pressed inward at the opening of the mounting groove 121, the main body component 31 moves in the direction toward the elastic component 32, and the elastic component 32 is further compressed. The first locking part 311 and the second locking part 312 move toward the elastic component 32 until they separate from the latching parts 71. The first locking part 311 and the second locking part 312 release their limiting and fixing effect on the latching part 71, and the watch strap quick-release assembly 3 enters the unlocked state, and the latching part 71 is in a detachable state. By providing two locking parts on both sides of the first mounting hole 310, the connection stability of the watch strap 7 can be improved, and the setting requirements of the first connector 4 can be met.

[0039] In some embodiments of this application, a second mounting hole 61 is provided on the first end of the third connector 6, and the first connector 4 passes through the second mounting hole 61 and is electrically connected to the first end of the third connector 6.

[0040] Optionally, the third connector 6 is a metal plate, such as a steel sheet. The third connector 6 has a second mounting hole 61, and the third connector 6 is fitted onto the outer periphery of the first connector 4 through the second mounting hole 61. The second mounting hole 61 contacts the first connector 4 to realize the electrical connection between the first connector 4 and the third connector 6.

[0041] like Figure 1 In the middle, the third connector 6 is a bent metal plate. One end of the metal plate is electrically connected to the first connector 4 through the second mounting hole 61, and the other end of the metal plate extends towards the main board 2 and is electrically connected to the main board 2 through the spring piece 8.

[0042] In some embodiments of this application, at least one sealing ring 41 is provided circumferentially for the first connector 4. The sealing ring 41 is located between the second connector 5 and the watch strap quick-release assembly 3. The first connector 4 is sealed to the through hole a through the sealing ring 41.

[0043] See Figure 1 The first connector 4 has an annular groove on its outer periphery, located at the end furthest from the metal frame 11. This groove is situated between the second connector 5 and the quick-release strap assembly 3, preventing water from entering the watch body through the quick-release assembly 3 and achieving a 5 atm water resistance rating. It should be noted that... Figure 1 The diagram shows only one sealing ring 41. In actual implementation, two or more sealing rings 41 can be set to improve waterproof performance.

[0044] In some embodiments of this application, the first connector 4 is a screw, and the third connector 6 is a nut. The nut includes a nut body and a threaded hole opened in the nut body, and the screw is fixedly connected to the threaded hole. The third connector 6 is sandwiched between the nut and the inner sidewall of the plastic housing 12.

[0045] See Figure 1 The threaded hole of the nut body faces the through hole a. The third connector 6 is clamped between the nut and the inner wall of the plastic housing 12. The metal frame 11, plastic housing 12, watch strap quick-release assembly 3, and third connector 6 are fixedly connected by nuts and screws. The overall structure is easy to install and disassemble. Moreover, the metal nuts and screws can further increase the radiation area of ​​the antenna radiator and improve the antenna's radiation performance.

[0046] It should be noted that the first connecting part 4 being a screw and the third connecting part 6 being a nut are merely examples and are not intended to be limiting. In actual implementation, the first connecting part 4 and the second connecting part 5 can also be fixedly connected by welding or snap rings.

[0047] In related technologies, the solution of using steel inserts injection-molded into a plastic frame to achieve long-distance connection between the metal frame and the main board suffers from complex processes, long production cycles, and low production line yield. For example, if a sealing ring is required, it needs to be injection-molded again after the insert steel sheet is injection-molded; the spring needs to be precisely positioned in three dimensions using laser positioning equipment; and there are gaps between the steel insert injection-molded into the plastic frame and the plastic, resulting in poor waterproofing.

[0048] Compared to existing solutions, the solution in this application uses a mechanical coupling structure of the first connector 4, the second connector 5, the third connector 6, and the metal frame 11 to power the antenna radiator to the motherboard 2, eliminating the need for complex manufacturing processes. Furthermore, the first connector 4, the second connector 5, the third connector 6, and the metal frame 11 are assembled using standard mounting holes, and disassembly of the first connector 4 and the second connector 5 allows for complete disassembly, reducing maintenance costs and improving product manufacturing yield.

[0049] This application embodiment also provides a watch, including a watch strap 7 and a watch body as described above; the watch strap 7 is provided with at least one snap-fit ​​part 71, and the snap-fit ​​part 71 is detachably connected to the watch strap quick-release assembly 3.

[0050] The snap-fit ​​part 71, also known as the head piece, is used to lock and connect with the quick-release strap assembly 3.

[0051] In some embodiments of this application, the snap-fit ​​part 71 and the quick-release strap assembly 3 are both made of metal, and the antenna radiator is formed on the snap-fit ​​part 71, the quick-release strap assembly 3 and the metal frame 11.

[0052] See Figure 1 The first connector 4 contacts the main body 31 of the watch strap quick-release assembly 3, and the main body 31 contacts the snap-fit ​​part 71. In this way, the metal frame 11, the main body 31, the snap-fit ​​part 71, the first connector 4, the second connector 5 and the third connector 6 are all electrically connected to the motherboard, thereby increasing the number of antenna radiators and improving the radiation performance of the antenna.

[0053] In some embodiments of this application, the end of the watch strap 7 facing the watch body is provided with a first metal lug 72b and a second metal lug 72c;

[0054] When the snap-fit ​​part 71 is locked and connected to the watch strap quick-release assembly 3, the first metal lug 72b and the second metal lug 72c are electrically connected to the metal frame 11, and the antenna radiator is formed on the first metal lug 72b, the second metal lug 72c and the metal frame 11.

[0055] Optionally, the first metal lug 71b and the second metal lug 72c are electrically connected to the metal frame 11 via an elastic conductive element.

[0056] Optionally, the first metal lug 71b and the second metal lug 72c are provided with protruding structures, which are electrically connected to the metal frame 11.

[0057] In this embodiment, the metal lugs can be electrically connected to the motherboard to serve as antenna radiators, which increases the antenna radiation width and improves the antenna radiation performance.
