Antenna, ear assembly, head assembly and wearable device

[0001] The present application claims priority to the Chinese patent application No. 202410838562.7, filed on June 25, 2024, and entitled "Antenna, ear assembly, head assembly and wearable device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of electronic products, and in particular to an antenna, an ear assembly, a head assembly and a wearable device. BACKGROUND

[0003] With the development of technology and people's pursuit of healthy and convenient life, wearable devices have gradually gained popularity among consumers. There are various types of wearable devices on the market at present, including smart watches, smart bracelets, smart glasses and the like, which can monitor physiological information of users, realize wireless communication, provide positioning services and the like. However, although wearable devices have been widely used, their performance still has certain limitations, which affects the user experience and the popularity of products. SUMMARY

[0004] The present application provides an antenna, an ear assembly, a head assembly and a wearable device, which can improve the performance of the product and meet the increasing demand of users.

[0005] In a first aspect, an embodiment of the present application provides an antenna, which comprises a sleeve and an inner rod, the inner rod being used to slide in the sleeve to fold or unfold the antenna; the antenna further comprises an electrical connection structure, the electrical connection structure being used to connect the sleeve and the inner rod. In the embodiment of the present application, the electrical connection structure can be connected with the sleeve and the inner rod at all times, or connected with the sleeve and the inner rod in some cases. When the inner rod is accommodated in place in the sleeve, the antenna is folded; when the inner rod is extended from the sleeve, the antenna is unfolded. When the antenna is unfolded, the effective length of the antenna increases, and the distance from the antenna to the shell of the electronic device can be increased, so that the clearance of the antenna is increased, and the radiation aperture of the antenna is increased. When the user holds the electronic device, or the electronic device is worn on the human body (the electronic device is a wearable device), the distance from the unfolded antenna to the hand or the part of the human body where the electronic device is located can be increased, so that the absorption of the antenna signal by the human body is reduced, and the hand model decrease is reduced. Therefore, when the antenna is unfolded, the performance of the antenna can be improved.

[0006] In an implementation form of the first aspect, the electrical connection structure is arranged on the inner rod, and the electrical connection structure is elastically stretchable and contractible in the radial direction of the inner rod. By making the electrical connection structure elastically stretchable and contractible in the radial direction of the inner rod, the reliable electrical connection between the inner rod and the sleeve can be ensured when the inner rod moves relative to the sleeve, and a damping hand feeling can be provided to increase the user experience.

[0007] In an implementation form of the first aspect, the inner rod is provided with a groove, an opening of the groove faces the inner wall of the first sleeve; the electrical connection structure comprises a first contact and a first elastic element, the first elastic element is located in the groove, opposite ends of the first elastic element abut against the first contact and the bottom wall of the groove respectively, and the first contact is connected with the inner wall of the first sleeve. Through the electrical connection structure and the assembling mode thereof in this implementation form, the inner rod and the sleeve can be kept in reliable electrical connection during the movement of the inner rod. In addition, the inner rod can accommodate the electrical connection structure by using the internal space of the inner rod, without occupying the space outside the inner rod, which is conducive to the miniaturization of the product.

[0008] In an implementation form of the first aspect, a part of the first contact is located in the groove, the first contact is a tubular structure with an open end, the opening of the first contact faces the bottom wall of the groove, and the first elastic element is accommodated in the inner cavity of the first contact. The electrical connection structure and the assembling mode thereof in this implementation form can better accommodate and fix the first elastic element, so that the assembling reliability of the electrical connection structure is better, and the reliable electrical connection between the inner rod and the sleeve is ensured.

[0009] In an implementation form of the first aspect, the electrical connection structure is arranged on the outer circumferential surface of the inner rod; when the antenna is folded, the electrical connection structure is not connected with the sleeve; when the antenna is unfolded, the electrical connection structure is connected with the sleeve. In this implementation form, the electrical connection structure can be independent of the inner rod and can be assembled to the inner rod, or the electrical connection structure can also be integrally arranged on the inner rod. When the antenna is folded, the electrical connection structure is not connected with the sleeve, so that the inner rod is not connected with the sleeve, and the inner rod does not contribute to the effective length of the antenna. By connecting the electrical connection structure with the sleeve when the antenna is unfolded, the inner rod is connected with the sleeve, so that the inner rod can contribute to the effective length of the antenna, thereby improving the performance of the antenna. This implementation form can meet the needs of the product.

[0010] In an implementation form of the first aspect, one end of the sleeve is provided with an end wall, the end wall is connected with the circumferential wall of the sleeve and is bent towards the inside of the circumferential wall relative to the circumferential wall; the antenna further comprises a ring, the ring is fixed to the outer circumferential surface of the inner rod and is in sliding connection with the inner wall of the sleeve; the outer circumferential surface of the inner rod is provided with a boss, the boss is located between the end wall and the ring; when the inner rod is exposed from the sleeve, the boss is clamped with the end wall. By forming a limiting structure of the boss-end wall between the inner rod and the sleeve, the movement of the inner rod can be limited. The ring is fixed on the inner rod, and the movement reliability of the inner rod can be ensured by increasing the movement damping of the inner rod. The ring can be an insulator or a conductor. When the ring is an insulator, the ring can play a damping and sealing role. When the ring is a conductor, the ring can also play an electrical connection role, so that the inner rod and the sleeve are always kept in electrical connection, thereby enabling the antenna to continuously adjust the electrical length to meet the needs of the product.

[0011] In an implementation form of the first aspect, the sleeve comprises a barrel and a connecting head, the opening of the sleeve is arranged at the barrel, the connecting head is arranged at an end of the barrel away from the opening of the barrel, and the connecting head is detachably connected with the barrel; the inner rod is arranged at the inner side of the barrel and is slidably connected with the inner wall of the barrel. This structure of the sleeve facilitates detachable implementation of the antenna. For example, the connecting head comprises a screwing part and a hinging part connected with each other, the screwing part is inserted into the barrel and is threadedly connected with the barrel.

[0012] In an implementation form of the first aspect, the hinging part is provided with a runway-shaped through hole, the connecting member passes through the runway-shaped through hole and is fixedly connected with another part of the antenna; when the antenna is in the folded state, the connecting member is located at an end of the runway-shaped through hole close to the barrel; and in the process of switching the antenna from the folded state to the unfolded state, the runway-shaped through hole is used for moving relative to the connecting member. This implementation form can make the hinging part move first and then rotate, so that the hinging part can be seamlessly connected.

[0013] In an implementation form of the first aspect, the connecting member comprises a screw cap, and the antenna further comprises a wave washer, the wave washer is sleeved on the outer periphery of the connecting member and abuts against the screw cap and the hinging part, and the wave washer can be elastically deformed. Since the hinging part moves first and then rotates, the freedom of movement is large, and the use of the wave washer can ensure reliable connection.

[0014] In an implementation form of the first aspect, two adjacent parts of the antenna are rotatably connected, and the antenna can be bent by rotation. When a user holds the electronic device or the electronic device is worn on the human body (the electronic device is a wearable device), the distance from the bent antenna to the skin surface of the hand or the skin surface of the part of the human body where the electronic device is located can be increased, so that the absorption of the antenna signal by the human body is further reduced, and the hand mode is further reduced, so that the performance of the antenna can be improved. In addition, rotating and bending the antenna can also meet some user needs, such as reducing the space occupation of the antenna or making the antenna avoid in order to facilitate user operation under the premise of improving the performance of the antenna.

[0097] 1. Antenna

[0098] An antenna that can be installed in the electronic device will be described below.

[0099] Fig. 1 shows an assembled structure of an antenna 1 in an embodiment, and Fig. 2 shows an exploded structure of the antenna 1 of Fig. 1.

[0100] As shown in Figs. 1 and 2, the antenna 1 can include a first hinge joint 10, a first sleeve 11, a limiting member 12, a connecting joint 13, an inner rod 14, a first electrical connection structure 15, a second sleeve 16, a second electrical connection structure 17, a connecting member 18, and a gasket 19, etc. The first sleeve 11 and the second sleeve 16 can both be referred to as sleeves. The first hinge joint 10 can slide within the first sleeve 11 (to be described below), and the first hinge joint 10 can also be considered as an inner rod.

[0101] Fig. 3 shows a cross-sectional structure of the first sleeve 11 of Fig. 2 (in the embodiments of the present application, if not otherwise specified, the cross-section of the cross-sectional view of a symmetric component is its symmetry plane). As shown in Figs. 2 and 3, the first sleeve 11 can have a tubular structure with open ends. For example, the first sleeve 11 can have a tubular body 11b, and an outer peripheral surface of one end of the tubular body 11b (the outer surface around the axis of the first sleeve 11, the same below) can have a limiting portion 11a protruding therefrom, which can surround the outer peripheral surface for one turn. The limiting portion 11a can have a skirt 11c extending radially inwardly of the first sleeve 11, which can also surround the axis of the first sleeve 11 for one turn. The one end of the tubular body 11b, for example, the end facing away from the limiting portion 11a, can have external threads. In another embodiment, the structure of the first sleeve 11 can be designed as required, and is not limited to the above, for example, the first sleeve 11 can not have the limiting portion 11a and / or the external threads.

[0102] As shown in Figs. 2 and 3, the limiting member 12 can be a nut or a structure similar to a nut, and one end of the limiting member 12 can have a skirt 12a extending radially inwardly of the limiting member 12, which can also surround the axis of the limiting member 12 for one turn. The limiting member 12 can be threadedly connected with the first sleeve 11, and the skirts 12a and 11c can be located at opposite ends of an assembly formed by the limiting member 12 and the first sleeve 11, respectively. It can be understood that the assembly formed by the limiting member 12 and the first sleeve 11 can also be referred to as a sleeve. In another embodiment, the limiting member 12 is not limited to being or similar to a nut structure, but can be connected with the first sleeve 11 as required, and the limiting member 12 and the first sleeve 11 are not limited to being threadedly connected, but can be connected in any other type of detachable or non-detachable manner. Alternatively, the limiting member 12 can not be provided.

[0103] As shown in FIG. 4 and FIG. 5, the first hinge joint 10 can be a column structure, for example, and a ring-shaped protrusion 10a can be formed on the first hinge joint 10 and can surround the axis of the first hinge joint 10. A groove 10b can be formed in the first hinge joint 10 and can extend in the radial direction of the first hinge joint 10. The groove 10b can be formed, for example, in the region of the ring-shaped protrusion 10a, and the opening of the groove 10b can be formed in the outer circumferential surface of the ring-shaped protrusion 10a. A through hole 10c, which can be a threaded hole, for example, can also be formed in the first hinge joint 10. In other embodiments, the first hinge joint 10 can be designed as needed and is not limited to the above, for example, the first hinge joint 10 can not have the ring-shaped protrusion 10a, the groove 10b, and / or the through hole 10c.

[0104] In this embodiment, the second electrical connection structure 17 is independent of the first hinge joint 10 and the first sleeve 11, and the second electrical connection structure 17 is connected to the first hinge joint 10 and the first sleeve 11 through an assembly process. FIG. 6 shows the assembly cross-sectional structure of the first hinge joint 10 and the second electrical connection structure 17.

[0105] In combination with FIG. 6 and FIG. 2, the second electrical connection structure 17 can include a second elastic member 171 and a second contact member 172, for example. The second elastic member 171 has elastic expansion and contraction properties, for example, and can be a spring or the like. The second contact member 172 is a rigid member and is used to transmit the elastic force of the second elastic member 171. The second contact member 172 can be a cylindrical structure with an open end, for example, and the second elastic member 171 can be installed in the inner cavity of the second contact member 172.

[0106] As shown in FIG. 6, the second electrical connection structure 17 can be installed in the groove 10b of the first hinge joint 10, wherein the opening of the second contact member 172 can face the bottom wall of the groove 10b, the opposite ends of the second elastic member 171 can abut the bottom wall of the groove 10b and the second contact member 172 respectively, and the second contact member 172 can protrude out of the opening of the groove 10b. As will be described below, the part of the second contact member 172 protruding out of the opening of the groove 10b can abut the inner wall of the first sleeve 11, so that the second electrical connection structure 17 can elastically connect the first hinge joint 10 and the first sleeve 11. Due to the presence of the second elastic member 171, the second electrical connection structure 17 can have elastic expansion and contraction properties in the radial direction of the first hinge joint 10 (or the radial direction of the first sleeve 11), and the second electrical connection structure 17 can ensure reliable mechanical and electrical contact between the first hinge joint 10 and the first sleeve 11 throughout the sliding process of the first hinge joint 10 in the first sleeve 11, and can also provide a damping feel.

[0107] As can be understood from the above, the structure of the second contact member 172 is not limited to a cylindrical structure, and can be adjusted as desired, provided that the second contact member 172 connects the second elastic member 171 and the inner wall of the first sleeve 11. For example, the second contact member 172 can be designed as a plate-shaped structure, such that the second contact member 172 is connected between the second elastic member 171 and the inner wall of the first sleeve 11. Alternatively, the second contact member 172 can be omitted, and the second elastic member 171 can be used to directly connect the first hinge joint 10 and the first sleeve 11.

[0108] In some embodiments of the present application, a recess 10b having a certain depth is formed in the first hinge joint 10 in the radial direction, and the second electrical connection structure 17 is fitted into the recess 10b. In this way, the second electrical connection structure 17 can be accommodated in the internal space of the first hinge joint 10, without occupying the space outside the first hinge joint 10, which is conducive to the miniaturization of the product. In another embodiment of the present application, the recess 10b can not be provided on the first hinge joint 10, and the second electrical connection structure can be fixed to the outer circumferential surface of the first hinge joint 10, or to the inner wall of the first sleeve 11. It can be understood that, in order to reliably mount the second electrical connection structure, when the second electrical connection structure is mounted to the first hinge joint 10, a recess can also be provided on the first hinge joint 10, and the second electrical connection structure is mounted in the recess, which can be shallower than the recess 10b described above; when the second electrical connection structure is mounted to the inner wall of the first sleeve 11, a recess can also be formed in the inner wall of the first sleeve 11, and the second electrical connection structure is mounted in the recess. The specific structure of the second electrical connection structure is not limited, and can be, for example, a sheet-shaped structure, a block-shaped structure, a ring-shaped structure, etc., as long as it can connect the first hinge joint 10 and the first sleeve 11. The second electrical connection structure can have radial elastic expansion and contraction properties, or can have substantially no radial elastic expansion and contraction properties.

[0109] In another embodiment of the present application, the second electrical connection structure can only play an electrical connection role when the first hinge joint 10 is slid to a certain position in the first sleeve 11; when the first hinge joint 10 is in other positions, the second electrical connection structure cannot play an electrical connection role. For example, referring to FIG. 6 and FIG. 3, in this embodiment, the second electrical connection structure 17 including the second elastic member 171 and the second contact member 172 is not provided, and instead, a ring-shaped protrusion 10a provided on the outer circumferential surface of the first hinge joint 10 is used as the second electrical connection structure. The ring-shaped protrusion 10a can be integrally provided on the outer circumferential surface of the first hinge joint 10 or connected to the outer circumferential surface of the first hinge joint 10 through an assembly process. The ring-shaped protrusion 10a has a radial gap with the inner wall of the first sleeve 11. When the first hinge joint 10 is located at the skirt 11c of the first sleeve 11 and the ring-shaped protrusion 10a contacts the skirt 11c, the ring-shaped protrusion 10a electrically connects the first hinge joint 10 and the first sleeve 11; when the first hinge joint 10 is located at the skirt 12a of the limiting member 12 and the ring-shaped protrusion 10a contacts the skirt 12a, the ring-shaped protrusion 10a electrically connects the first hinge joint 10, the limiting member 12 and the first sleeve 11; when the first hinge joint 10 is slid to a position such that the ring-shaped protrusion 10a does not contact the skirt 11c and the skirt 12a, the ring-shaped protrusion 10a does not play an electrical connection role, and the first hinge joint 10 is not electrically connected to the first sleeve 11. It will be described below that when the ring-shaped protrusion 10a contacts the skirt 12a, the antenna 1 can be unfolded. Therefore, it can be said that when the antenna 1 is unfolded, the ring-shaped protrusion 10a is electrically connected to the first sleeve 11. In this embodiment, in order to make the mechanical connection between the first hinge joint 10 and the first sleeve 11 reliable and increase the damping feeling, a ring-shaped ring can be sleeved on the outer circumferential surface of the first hinge joint 10, and the ring-shaped ring is an insulator.

[0110] As shown in FIG. 2, in one embodiment, the second sleeve 16 can include a second hinge joint 162 and a sleeve body 161, and the two can form a detachable connection. Such a design facilitates the assembly and disassembly of the antenna 1. In another embodiment, the second hinge joint 162 and the sleeve body 161 can form a non-detachable connection.

[0111] FIG. 7 schematically shows the structure of the second hinge joint 162 from different perspectives. As shown in FIG. 7, the second hinge joint 162 can be generally a column structure. The second hinge joint 162 can be provided with a through hole 162a, and one end of the second hinge joint 162 can have an external thread 162b. In other embodiments, the structure of the second hinge joint 162 can be designed as needed and is not limited to the above, for example, the second hinge joint 162 can not be provided with the through hole 162a and / or the external thread 162b.

[0112] The second hinge joint 162 is used to form a rotating connection with the first hinge joint 10. FIG. 8 schematically shows the relative position relationship between the second hinge joint 162 and the first hinge joint 10, and FIG. 9 schematically shows the assembled structure of the second hinge joint 162 and the first hinge joint 10.

[0113] As shown in FIGS. 8-9, the connecting member 18 can pass through the gasket 19 and be connected with the through hole 162a on the second hinge joint 162 and the through hole 10c on the first hinge joint 10, so as to form a rotating connection between the second hinge joint 162 and the first hinge joint 10. For example, the connecting member 18 can be a screw, and the screw cap of the connecting member 18 can be arranged in sequence with the gasket 19, the second hinge joint 162 and the first hinge joint 10, that is, the connecting member 18 can pass through the gasket 19, the second hinge joint 162 and the first hinge joint 10 in sequence during assembly. Alternatively, in another embodiment, the holes for forming the rotating connection in the second hinge joint 162 and the first hinge joint 10 can be exchanged, and the screw cap of the connecting member 18 can be arranged in sequence with the gasket 19, the first hinge joint 10 and the second hinge joint 162, that is, the connecting member 18 can pass through the gasket 19, the first hinge joint 10 and the second hinge joint 162 in sequence during assembly.

[0114] For example, the gasket 19 can have elastic deformation performance, for example, the gasket 19 can be a wave gasket or other elastic gasket. Through the elastic deformation performance of the gasket 19, the connection between the connecting member 18, the second hinge joint 162 and the first hinge joint 10 can be more reliable, and the gasket 19 can avoid loosening or abnormal sound, ensure the reliable electrical connection between the second hinge joint 162 and the first hinge joint 10, and also can play a buffering and damping role. In another embodiment, the gasket 19 can also have substantially no elastic deformation performance, or the gasket 19 can be omitted.

[0115] In another embodiment, the rotating connection between the second hinge joint 162 and the first hinge joint 10 can be achieved by other suitable means, which is not limited to using the connecting member 18. For example, the second hinge joint 162 and the first hinge joint 10 can be designed in structure, and a pin shaft and a pin hole can be formed on them respectively, so that they are directly hinged.

[0116] FIG. 10 schematically shows the perspective structure of the cylinder body 161, and FIG. 11 schematically shows the cross-sectional structure of the cylinder body 161 shown in FIG. 10. As shown in FIGS. 10-11, the cylinder body 161 can have a cylindrical structure with both ends open. One end of the cylinder body 161 can be provided with an internal thread 161a, and the other end can be provided with a skirt 161b extending to the inside of the cylinder body 161 along the radial direction of the cylinder body 161, and the skirt 161b can surround the axis of the cylinder body 161 for one turn. In another embodiment, the cylinder body 161 can not be provided with the internal thread 161a and / or the skirt 161b.

[0117] As shown in FIG. 7 and FIG. 11, the external thread 162b of the second hinge joint 162 can be connected with the internal thread 161a of the barrel 161, so that the second hinge joint 162 and the barrel 161 form a detachable connection. In another embodiment, the second hinge joint 162 and the barrel 161 can form a non-detachable connection, for example, the two can be welded. Alternatively, the second sleeve 16 can be manufactured by an integral process, and the second hinge joint 162 and the barrel 161 are integrated.

[0118] FIG. 12 shows a perspective view of the inner rod 14. As shown in FIG. 12, the inner rod 14 can be generally cylindrical. The outer diameter of one end of the inner rod 14 is larger, and the part with the larger outer diameter can be referred to as the limiting portion 14b. The other end of the inner rod 14 can form an external thread 14c. The inner rod 14 can also be provided with a groove 14a, which can be provided, for example, in the area where the limiting portion 14b is located. The groove 14a can extend in the radial direction of the inner rod 14, and the opening of the groove 14a can be formed on the outer circumferential surface of the limiting portion 14b. In another embodiment, the structure of the inner rod 14 can be designed as needed and is not limited to the above, for example, the inner rod 14 can not contain the limiting portion 14b, the groove 14a and / or the external thread 14c.

[0119] FIG. 13 shows an assembled structure of the inner rod 14, the first electrical connection structure 15, the barrel 161 of the second sleeve 16, and the connector 13.

[0120] As shown in FIG. 13, the inner rod 14 can be fitted into the barrel 161, and the limiting portion 14b of the inner rod 14 can be close to the internal thread 161a of the barrel 161. According to the above, the limiting portion 14b is also close to the second hinge joint 162. When the inner rod 14 slides to the right in the barrel 161 to the limit position, the limiting portion 14b can be in contact with the skirt 161b of the barrel 161, and the skirt 161b blocks the movement of the limiting portion 14b to limit the inner rod 14 at the limit position. The external thread 14c of the inner rod 14 can be away from the internal thread 161a and exposed outside the barrel 161. The connector 13 has an internal thread, which can be, for example, a nut, and the connector 13 is threadedly connected with the external thread 14c of the inner rod 14. In another embodiment, the connector 13 and the end of the inner rod 14 exposed outside the barrel 161 can form other forms of detachable or non-detachable connection, or the connector 13 can not be provided.

[0121] In one embodiment, the first electrical connection structure 15 is independent of the inner rod 14 and the barrel 161, and the first electrical connection structure 15 is connected with the inner rod 14 and the barrel 161 by an assembly process.

[0122] In combination with FIG. 2 and FIG. 13, the first electrical connection structure 15 can include a first elastic member 151 and a first contact member 152. The first elastic member 151 has elastic performance, such as a spring or the like. The first contact member 152 is a rigid member for conducting the elastic force of the first elastic member 151. The first contact member 152 can be a cylindrical structure with one end open, and the first elastic member 151 can be installed in the inner cavity of the first contact member 152.

[0123] As shown in FIG. 13, the first electrical connection structure 15 can be installed in the groove 14a of the inner rod 14, wherein the opening of the first contact member 152 can face the bottom wall of the groove 14a, the opposite ends of the first elastic member 151 can abut the bottom wall of the groove 14a and the first contact member 152 respectively, and the first contact member 152 can be exposed from the opening of the groove 14a. The part of the first contact member 152 exposed from the opening of the groove 14a can abut the inner wall of the barrel 161, so that the first electrical connection structure 15 can elastically connect the inner rod 14 and the barrel 161. Due to the presence of the first elastic member 151, the first electrical connection structure 15 can have elastic performance along the radial direction of the inner rod 14 (or the radial direction of the barrel 161), and the first electrical connection structure 15 can ensure reliable mechanical and electrical contact between the inner rod 14 and the barrel 161 during the entire sliding process of the inner rod 14 in the barrel 161, and can also provide a damping feel.

[0124] According to the above description, it can be understood that the structure of the first contact member 152 can be adjusted as needed under the premise of ensuring that the first contact member 152 connects the first elastic member 151 and the inner wall of the barrel 161, and the first contact member 152 is not limited to a cylindrical structure. For example, the first contact member 152 can be designed as a plate structure, so that the first contact member 152 is connected between the first elastic member 151 and the inner wall of the barrel 161. Alternatively, the first contact member 152 can be omitted, and the first elastic member 151 can be directly used to connect the inner rod 14 and the barrel 161.

[0125] In some embodiments of the present application, a groove 14a with a certain depth is formed on the inner rod 14 in the radial direction, and the first electric connection structure 15 is arranged in the groove 14a. The inner space of the inner rod 14 can be used to accommodate the first electric connection structure 15, and the space outside the inner rod 14 is not occupied, which is conducive to the miniaturization of the product. In another embodiment of the present application, the groove 14a can not be provided on the inner rod 14, and the first electric connection structure can be fixed to the outer circumferential surface of the inner rod 14 or the inner wall of the barrel 161. It can be understood that, in order to reliably mount the first electric connection structure, when the first electric connection structure is mounted on the inner rod 14, a groove can also be provided on the inner rod 14, and the first electric connection structure is mounted in the groove. The groove can be shallower than the groove 14a described above; when the first electric connection structure is mounted on the inner wall of the barrel 161, a groove can also be formed on the inner wall of the barrel 161, and the first electric connection structure is mounted in the groove. The specific structure of the first electric connection structure is not limited, for example, it can be in the form of a sheet, a block, a ring, etc., as long as it can connect the inner rod 14 and the barrel 161. The first electric connection structure can have radial elastic expansion performance, or can have substantially no radial elastic expansion performance.

[0126] In another embodiment of the present application, the first electric connection structure can only play an electric connection role when the inner rod 14 is slid to a certain position in the barrel 161; when the inner rod 14 is located at other positions, the first electric connection structure cannot play an electric connection role. For example, referring to FIG. 13, in this embodiment, the first electric connection structure 15 including the first elastic member 151 and the first contact member 152 is not provided, and a limiting portion 14b provided on the outer circumferential surface of the inner rod 14 is used as the first electric connection structure. The limiting portion 14b can be integrally provided on the outer circumferential surface of the inner rod 14 or connected to the outer circumferential surface of the inner rod 14 through an assembly process. The limiting portion 14b has a radial gap with the inner wall of the barrel 161. When the limiting portion 14b of the inner rod 14 is slid to the skirt 161b of the barrel 161 and the limiting portion 14b contacts the skirt 161b, the limiting portion 14b electrically connects the inner rod 14 and the barrel 161; when the inner rod 14 is located at a position such that the limiting portion 14b does not contact the skirt 161b (for example, the position shown in FIG. 13), the limiting portion 14b does not play an electric connection role, and the inner rod 14 and the barrel 161 are not electrically connected. It will be described below that when the limiting portion 14b contacts the skirt 161b, the antenna 1 can be unfolded, and therefore it can be said that the limiting portion 14b is connected to the barrel 161 when the antenna 1 is unfolded. When the antenna 1 is folded, the limiting portion 14b is located at the position shown in FIG. 13, and therefore it can be said that the limiting portion 14b is not connected to the barrel 161 when the antenna 1 is folded. In this embodiment, in order to reliably mechanically connect the inner rod 14 and the barrel 161 and increase the damping feeling, an annular ring can be sleeved on the outer circumference of the inner rod 14, and the annular ring is an insulator.

[0127] Figure 14 illustrates a cross-sectional structure of the antenna 1 of Figure 1.

[0128] As shown in Figure 14, the first hinge 10 and the second electrical connection structure 17 can be mounted in the first sleeve 11. A portion (e.g., the left end) of the first hinge 10 can be exposed outside the first sleeve 11 for a user to press. The annular protrusion 10a of the first hinge 10 can be in contact with the skirt 11c of the first sleeve 11. The second electrical connection structure 17 elastically connects the first hinge 10 and the first sleeve 11.

[0129] As shown in Figure 14, the second sleeve 16 can be mounted in the first sleeve 11, and the second sleeve 16 can slide in the first sleeve 11. The second hinge 162 of the second sleeve 16 can be rotationally connected with the first hinge 10.

[0130] As shown in Figure 14, the inner rod 14 can be slidably mounted in the second sleeve 16, and the first electrical connection structure 15 elastically connects the inner rod 14 and the second sleeve 16. An end (e.g., the right end) of the inner rod 14 can be exposed outside the second sleeve 16 and connected with the connecting head 13. The connecting head 13 can pass through the limiting member 12 and be exposed for a user to pull.

[0131] The antenna 1 of the embodiment can be mounted in an electronic device. The antenna 1 is electrically connected with a communication module in the electronic device. The antenna 1 can receive radio frequency signals fed by the communication module and realize electromagnetic wave radiation.

[0132] The communication module refers to all devices or circuits used for generating, processing, and transmitting radio frequency signals. The communication module includes, but is not limited to, a modem, a baseband processor, a radio frequency chip (RF transceiver), a radio frequency front end, a ground feed, a matching circuit, a matching device, a transmission cable, etc. According to the functional type of the communication module, the antenna 1 can be one or more of 2G / 3G / 4G / 5G cellular antennas, or one or more of non-cellular antennas such as wireless local area networks (WLAN), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared (IR), etc.

[0133] The antenna 1 of the embodiment can be folded or unfolded along the axial direction. Figure 14 illustrates a folded state of the antenna 1. In the folded state, the length of the antenna 1 is the shortest. From the folded state shown in Figure 14, the antenna 1 can be gradually unfolded to increase the length, and the posture can also be changed. This will be described below.

[0134] Referring to FIG. 14, the radio frequency signal fed into the communication module can be received by the first sleeve 11 of the antenna 1, and can be transmitted from the first sleeve 11 to the second electrical connection structure 17, the first hinge joint 10, the second sleeve 16, the first electrical connection structure 15, the inner rod 14, and the like in sequence.

[0135] Referring to FIGS. 14 and 15, the user can pull the inner rod 14 from the connector 13, so that the inner rod 14 slides out of the second sleeve 16 to the limit position, so that the antenna 1 is in the first unfolded state shown in FIG. 15. As shown in FIG. 15, in the first unfolded state, the limiting portion 14b of the inner rod 14 is in contact with the skirt 161b of the second sleeve 16, so that the inner rod 14 cannot continue to slide out of the second sleeve 16. During the sliding process of the inner rod 14 out of the second sleeve 16, the first electrical connection structure 15 having radial elastic expansion performance can ensure reliable contact between the inner rod 14 and the second sleeve 16, and ensure electrical connection between the inner rod 14 and the second sleeve 16, so that the inner rod 14 can always receive radio frequency signals from the second sleeve 16, so that the inner rod 14 and the second sleeve 16 can both be used as antennas to realize signal transmission and reception; in addition, it can also provide a damping hand feeling and increase user experience.

[0136] In another embodiment described above, referring to FIGS. 14 and 15, the limiting portion 14b can be used as the first electrical connection structure. When the limiting portion 14b is in contact with the skirt 161b, i.e. in the first unfolded state shown in FIG. 15, the limiting portion 14b electrically connects the inner rod 14 and the second sleeve 16, so that the inner rod 14 and the second sleeve 16 can both be used as antennas to realize signal transmission and reception; when the limiting portion 14b is not in contact with the skirt 161b and is not in contact with the second hinge joint 162, the limiting portion 14b does not play an electrical connection role, the inner rod 14 and the second sleeve 16 are not electrically connected, and the inner rod 14 cannot receive radio frequency signals from the second sleeve 16, so the inner rod 14 cannot be used as an antenna; as shown in FIG. 14, when the limiting portion 14b is in contact with the second hinge joint 162, the inner rod 14 is accommodated in the second sleeve 16 and the connector 13, and the inner rod 14 does not contribute to the length of the antenna, and it can be considered that the inner rod 14 is not used as an antenna.

[0137] When the antenna 1 is unfolded, for example, unfolded to the first unfolded state shown in FIG. 15, the length of the antenna 1 increases, the distance between the antenna 1 and the shell of the electronic device becomes larger, so that the clearance of the antenna 1 increases, and the radiation aperture of the antenna 1 increases. When the user holds the electronic device, or the electronic device is worn on the human body (the electronic device is a wearable device), the distance between the unfolded antenna 1 and the hand or the part of the human body where the electronic device is located can be increased, so that the absorption of the antenna signal by the human body is reduced, and the hand model is reduced. In summary, after the antenna 1 is unfolded, the antenna performance of the antenna 1 can be improved.

[0138] Referring to FIG. 15, it can be understood that when the user unfolds the antenna 1 but does not reach the first unfolded state, the antenna performance of the antenna 1 can still be improved.

[0139] Referring to FIGS. 15 and 16, the user can continue to pull the inner rod 14 in the same direction, so that the inner rod 14 drives the second sleeve 16, and then the second sleeve 16 drives the first hinge joint 10 to slide out of the first sleeve 11, so that the first hinge joint 10 slides to the right end of the first sleeve 11, so that the antenna 1 is in the second unfolded state shown in FIG. 16. As shown in FIG. 16, in the second unfolded state, the annular protrusion 10a of the first hinge joint 10 is in contact with the skirt 12a of the limiting piece 12, so that the first hinge joint 10 cannot continue to slide out of the first sleeve 11. In the process of sliding of the first hinge joint 10, the second electric connection structure 17 having the radial elastic extension performance can ensure reliable contact between the first hinge joint 10 and the first sleeve 11, and ensure the electrical connection between the first hinge joint 10 and the first sleeve 11, so that the first hinge joint 10 can always receive the radio frequency signal from the first sleeve 11, so that the first hinge joint 10 and the first sleeve 11 can both serve as an antenna to realize signal transmission and reception; in addition, a damping hand feeling can be provided, and user experience can be improved.

[0140] In another embodiment described above, referring to FIGS. 15 and 16, the annular protrusion 10a can be used as the second electric connection structure. When the annular protrusion 10a is in contact with the skirt 12a, that is, in the second unfolded state shown in FIG. 16, the annular protrusion 10a electrically connects the first hinge joint 10 and the first sleeve 11, so that the first hinge joint 10 and the first sleeve 11 can both serve as an antenna to realize signal transmission and reception; when the annular protrusion 10a is located between the skirt 11c and the skirt 12a and does not contact both of them, the annular protrusion 10a does not play an electrical connection role, the first hinge joint 10 and the first sleeve 11 are not electrically connected, and the first hinge joint 10 cannot receive the radio frequency signal from the first sleeve 11, so the first hinge joint 10 cannot be used as an antenna.

[0141] When the antenna 1 is unfolded, for example, to the second unfolded state shown in FIG. 16, the length of the antenna 1 is further increased, and the distance between the antenna 1 and the shell of the electronic device is further increased, so that the clearance of the antenna 1 is increased, and the radiation aperture of the antenna 1 is increased. When the user holds the electronic device, or the electronic device is worn on the human body (the electronic device is a wearable device), the distance between the unfolded antenna 1 and the hand or the part of the human body where the electronic device is located can be increased, so that the absorption of the antenna signal by the human body is further reduced, and the hand model is further reduced. In summary, when the antenna 1 is unfolded, the antenna performance of the antenna 1 can be improved.

[0142] As shown in FIG. 16, it can be understood that when the user unfolds the antenna 1 from the first unfolded state, but does not reach the second unfolded state, the antenna performance of the antenna 1 can still be improved.

[0143] As shown in FIGS. 16 and 17, the user can also rotate the second sleeve 16 around the first hinge 10, for example, by 90 degrees or other angles, so that the antenna 1 is in a third unfolded state. The present embodiment does not limit the rotation direction of the second sleeve 16. For example, the second sleeve 16 can be rotated in the counterclockwise direction, or in the clockwise direction. When the user holds the electronic device, or the electronic device is worn on the human body (the electronic device is a wearable device), in the third unfolded state, the distance from the antenna 1 to the skin surface of the hand or the part of the human body where the electronic device is located can be increased, so that the absorption of the antenna signal by the human body is further reduced, and the hand mode is further reduced, so that the antenna performance of the antenna 1 can be improved. In addition, adjusting the antenna 1 to the third unfolded state can also meet some user needs, for example, reducing the space occupation of the antenna 1 or avoiding the antenna 1 to operate under the premise of improving the antenna performance.

[0144] It can be understood that the relative movement between the components of the antenna 1 is bidirectional. For example, as shown in FIG. 16, the relative movement between the inner rod 14 and the second sleeve 16 is bidirectional, that is, the inner rod 14 can also slide into the second sleeve 16, for example, slide to the left in FIG. 16; the relative movement between the second sleeve 16 and the first sleeve 11 is bidirectional, for example, the second sleeve 16 can also slide to the left end of the first sleeve 11 in FIG. 16. For example, as shown in FIG. 17, the relative movement between the second sleeve 16 and the first hinge 10 is bidirectional, for example, the second sleeve 16 can also rotate clockwise around the first hinge 10 in FIG. 17. As shown in FIG. 17, the user can push the inner rod 14 into the second sleeve 16, and then rotate the second sleeve 16 and the inner rod 14 clockwise; or the user can first rotate the second sleeve 16 clockwise, and then push the inner rod 14 into the second sleeve 16.

[0145] As can be easily understood from the foregoing, the antenna 1 of the present embodiment can be axially telescopic twice, and can also be rotated and bent. The antenna 1 can be unfolded in the above manner, so as to improve the antenna performance and improve the user experience.

[0146] It can be understood that by adjusting the number of inner rods and sleeves in the antenna, the antenna can be axially telescopic for any number of times. For example, in another embodiment, the antenna can have one inner rod and one sleeve, and can be axially telescopic for one time. Or in another embodiment, the antenna can have multiple inner rods and multiple sleeves, and the sleeves and inner rods are nested in the order of sleeve-inner rod-sleeve-inner rod-…, so that the antenna can be axially telescopic for multiple times.

[0147] As shown in Figs. 14-16, during the unfolding of the antenna 1 of the above embodiment, the first sleeve 11 with the largest outer diameter can be fixed, the inner rod 14 with the smallest outer diameter can be first extended to the right, and the second sleeve 16 with the larger outer diameter can be then extended to the right, i.e. the parts of the antenna 1 can be sequentially extended in the same direction in the order from thick to thin.

[0148] Referring to Fig. 14, in another embodiment, the inner rod 14 with the smallest outer diameter can be fixed, the first sleeve 11 with the largest outer diameter can be first moved to the left relative to the inner rod 14 and the second sleeve 16, and the second sleeve 16 with the larger outer diameter can be then moved to the left relative to the inner rod 14, so that the antenna 1 can be sequentially extended in the same direction in the order from thick to thin.

[0149] Alternatively, referring to Fig. 14, in another embodiment, the second sleeve 16 with the larger outer diameter can be fixed, the first sleeve 11 with the largest outer diameter can be moved to the left relative to the second sleeve 16, and the inner rod 14 with the smallest outer diameter can be moved to the right relative to the second sleeve 16, so that the antenna 1 can be respectively extended in opposite directions.

[0150] As shown in Fig. 17, the second sleeve 16 of the antenna 1 of the above embodiment can be axially movable and rotatable relative to the first sleeve 11, and the inner rod 14 can be axially movable but not rotatable relative to the second sleeve 16.

[0151] Referring to Fig. 17, in another embodiment, the inner rod 14 can be axially movable and rotatable relative to the second sleeve 16 after being extended from the second sleeve 16. For example, a component similar to the first hinge 10 can be arranged in the second sleeve 16, the inner rod 14 can be connected with a component similar to the second hinge 162 or the inner rod 14 can have a structure similar to the second sleeve 16 (including the sleeve body 161 and the second hinge 162), so that the inner rod 14 can be axially movable and rotatable relative to the second sleeve 16. In this embodiment, the installation position of the first electrical connection structure 15 can be similar to the installation position of the second electrical connection structure 17, so that the first electrical connection structure 15 connects the second sleeve 16 with the component similar to the first hinge 10.

[0152] Referring to Fig. 17, in another embodiment, the hinge structure of the first hinge 10 and the second hinge 162 can be cancelled, and the second sleeve 16 can be slidingly connected with the first sleeve 11, so that the second sleeve 16 can be axially movable but not rotatable relative to the first sleeve 11. In this embodiment, the second sleeve 16 and the first sleeve 11 can be reliably electrically connected through any suitable structure. In this embodiment, the inner rod 14 can be axially movable but not rotatable relative to the second sleeve 16, or the inner rod 14 can be axially movable and rotatable relative to the second sleeve 16.

[0153] In another embodiment, the antenna can not have the rotating connection design, and the antenna has no rotating bending function, but only axial telescopic function.

[0154] The following will take the above antenna 1 as an example to illustrate the assembly structure of the antenna in the electronic device.

[0155] FIGS. 18-20 are schematic diagrams of the assembly structure of the antenna 1 in the electronic device 2. The electronic device 2 can be a smart watch.

[0156] As shown in FIG. 18, in an embodiment, the electronic device 2 can include a main body 21 and the antenna 1, etc. The main body 21 is the main structural and functional part of the electronic device 2, and can include, for example, a housing 212, a display screen 211 mounted on the housing 212, and a communication module disposed in the housing 212, etc. The antenna 1 can be mounted on the housing 212, and a part of the antenna 1 can be exposed for the user to unfold or fold. For example, the limiting part 11a and the limiting member 12 of the antenna 1 can form a limiting fit with the housing 212 to fix the antenna 1 on the housing 212. The housing 212 can be provided with a feed point, and the housing 212 can be electrically connected with the communication module through the feed point, and the antenna 1 can be electrically connected with the communication module through the housing 212. For example, the axis of the antenna 1 can be substantially parallel to the display screen 211.

[0157] As shown in FIG. 18, for example, the housing 212 can include a housing body 212a and a head grain 212b, one side of the head grain 212b is connected with the housing body 212a, and the head grain 212b and the housing body 212a form a detachable connection or a non-detachable connection, and the other side of the head grain 212b can be connected with a wristband. The structure space of the housing body 212a is limited, and therefore the antenna 1 can be mounted on the head grain 212b, so that the structure space of the head grain 212b can be used to accommodate the antenna 1, and the housing body 212a can maintain a small size, which is beneficial to realize the miniaturization of the main body 21. It can be considered that the head grain 212b and the antenna 1 constitute a head grain assembly.

[0158] It can be understood that the provision of the head grain 212b and the arrangement of the antenna 1 in the head grain 212b are only examples, and are not a limitation on the embodiments of the present application. In another embodiment, the head grain 212b can be provided, and the antenna 1 can be arranged in the housing body 212a; or the antenna 1 can be arranged in the housing body 212a, and the head grain 212b can not be provided.

[0159] The antenna 1 in FIG. 18 can be in the first unfolded state as described above, i.e. the antenna 1 is axially elongated for the first time. The antenna 1 in FIG. 19 can be in the second unfolded state as described above, i.e. the antenna 1 is axially elongated for the second time. The antenna 1 in FIG. 20 can be in the third unfolded state as described above, i.e. the antenna 1 is further bent by rotation. In combination with FIGS. 18-20 and the above description, when the antenna 1 is unfolded, the distance between the antenna 1 and the housing 212 of the electronic device 2 becomes larger, so that the clearance of the antenna 1 is increased, and the radiation aperture of the antenna 1 is increased. When the antenna 1 is in the third unfolded state shown in FIG. 20, the distance between the antenna 1 and the surface of the hand can be increased, so that the absorption of the antenna signal by the human body is further reduced, and the hand model is further reduced, and thus the antenna performance of the antenna 1 can be improved. In addition, adjusting the antenna 1 to the third unfolded state can also meet some user needs, such as reducing the space occupation of the antenna 1 on the premise of improving the antenna performance, or making the antenna 1 avoid in order to be operated by the user.

[0160] It can be understood that the mounting position of the antenna 1 and the angle of the antenna 1 relative to the display screen 211 shown in FIGS. 18-20 are only examples and are not a limitation on the embodiments of the present application. According to product needs, the antenna 1 can be mounted at any position of the housing 212, and the angle of the antenna 1 relative to the display screen 211 can be any angle, for example, the axis of the antenna 1 can be substantially perpendicular to the display screen 211.

[0161] FIGS. 21-22 show the assembly structure of the antenna 3 in another embodiment, and FIG. 23 is an exploded view of the antenna 3 in FIG. 22. As shown in FIGS. 21-23, the antenna 3 can include a connecting head 30, an inner rod 37, a ring 38, a sleeve 31, a connecting piece 36, a gasket 39, a first hinge 35, an electrical connection structure 32, a connecting piece 33, and a knob 34.

[0162] As shown in FIGS. 22 and 23, the sleeve 31 can include a barrel 311 and a second hinge 312, which can be detachably connected, and such a design facilitates the assembly and disassembly of the antenna 3. In another embodiment, the barrel 311 and the second hinge 312 can be non-detachably connected.

[0163] FIG. 24 shows a cross-sectional structure of the barrel 311. As shown in FIG. 24, the barrel 311 can be a cylindrical structure with both ends open. For example, one end of the barrel 311 can have a skirt 311a extending radially inwardly of the barrel 311, and the skirt 311a can surround the axis of the barrel 311. The other end of the barrel 311 can be provided with an internal thread 311b. In another embodiment, the structure of the barrel 311 can be designed as needed, and is not limited to the above description, for example, the barrel 311 can not contain the skirt 311a and / or the internal thread 311b.

[0164] FIGS. 25 and 26 respectively illustrate the structure of the second hinge joint 312 from different perspectives. As shown in FIGS. 25 and 26, the second hinge joint 312 can be generally cylindrical in structure. One end of the second hinge joint 312 can be provided with an external thread 312a for connecting with an internal thread 311b of the barrel 311, so that the second hinge joint 312 is threadedly connected with the barrel 311. The second hinge joint 312 can also be provided with a runway-shaped through hole 312b (or waist-shaped through hole or elliptical through hole), which can be a stepped hole for example. The runway-shaped through hole 312b is used for mounting the connecting member 36 and the gasket 39, and the stepped hole facilitates the positioning of the gasket 39. The runway-shaped through hole 312b can be a smooth hole, i.e. the inner surface of the runway-shaped through hole 312b can be free of internal thread. In another embodiment, the structure of the second hinge joint 312 can be designed as required, and is not limited to the above description, e.g. the runway-shaped through hole 312b can be replaced by a circular hole, or the external thread 312a and / or the runway-shaped through hole 312b can be omitted.

[0165] FIGS. 27-29 respectively illustrate the structure of the first hinge joint 35 from different perspectives. As shown in FIGS. 27-29, the first hinge joint 35 can be generally cylindrical in structure. One end of the first hinge joint 35 can be provided with a mounting hole 35a, which can be a threaded hole for example, for mounting the connecting member 36. As shown in FIGS. 27-28, the first hinge joint 35 can also be provided with a mounting groove 35b for mounting the push block 34. As shown in FIGS. 28-29, the groove wall of the mounting groove 35b can be provided with a through hole 35c for the connecting member 33 to pass through, so that the connecting member 33 fixes the push block 34 in the mounting groove 35b. The first hinge joint 35 can also be provided with a recess 35d, which can extend in the radial direction of the first hinge joint 35, and the opening of the recess 35d can be formed on the outer peripheral surface of the first hinge joint 35. The recess 35d can not be in communication with the mounting groove 35b. The recess 35d is used for mounting the electrical connection structure 32. In another embodiment, the structure of the first hinge joint 35 can be designed as required, and is not limited to the above description, e.g. the first hinge joint 35 can not be provided with the mounting hole 35a, the mounting groove 35b, the through hole 35c and / or the recess 35d.

[0166] As shown in FIG. 30, the push block 34 can be generally block-shaped in structure, one end (e.g. the upper end in FIG. 30) of which can have an arc-shaped or arched surface, and the other end (e.g. the lower end in FIG. 30) of which can have a flat surface. The push block 34 can be provided with a mounting hole 34a for mounting the connecting member 33. The push block 34 is used for being fixed into the mounting groove 35b of the first hinge joint 35, and the push block 34 is used for being pushed by a user to move the antenna 3 (which will be described below). In another embodiment, the structure of the push block 34 can be designed as required, and is not limited to the above description. Alternatively, the push block 34 can be omitted.

[0167] Fig. 31 is an exploded structural schematic diagram for showing the relative position relationship of the second hinge joint 312, the first hinge joint 35, the connecting member 36, the gasket 39, the electrical connection structure 32, the push block 34, the connecting member 33, etc. Figs. 32 and 33 respectively show the assembled structure of the components in Fig. 31 from different perspectives.

[0168] As shown in Figs. 31-33, the connecting member 36 can pass through the gasket 39 and be connected with the runway-shaped through hole 312b on the second hinge joint 312 and the mounting hole 35a on the first hinge joint 35, so as to rotationally connect the second hinge joint 312 with the first hinge joint 35. For example, the connecting member 36 can be a screw, and the screw nut thereof can be arranged in sequence with the gasket 39, the second hinge joint 312 and the first hinge joint 35, i.e., in assembly, the connecting member 36 can pass through the gasket 39, the second hinge joint 312 and the first hinge joint 35 in sequence. Alternatively, in another embodiment, the holes for realizing the rotational connection in the second hinge joint 312 and the first hinge joint 35 can be interchanged, and the screw nut of the connecting member 36 can be arranged in sequence with the gasket 39, the first hinge joint 35 and the second hinge joint 312, i.e., in assembly, the connecting member 36 can pass through the gasket 39, the first hinge joint 35 and the second hinge joint 312 in sequence.

[0169] For example, the gasket 39 can have elastic deformation performance, such as a wave-shaped gasket or other elastic gasket. Through the elastic deformation performance of the gasket 39, the connection of the connecting member 36, the second hinge joint 312 and the first hinge joint 35 can be more reliable, avoiding looseness or abnormal sound, ensuring the reliable electrical connection of the second hinge joint 312 and the first hinge joint 35, and also playing a role of shock absorption and buffering. In another embodiment, the gasket 39 can also have substantially no elastic deformation performance, or the gasket 39 can be omitted.

[0170] In another embodiment, the rotational connection of the second hinge joint 312 and the first hinge joint 35 can be realized by other suitable means, not limited to using the connecting member 36. For example, the second hinge joint 312 and the first hinge joint 35 can be structurally designed to respectively form a pin shaft and a pin hole, so as to be directly hinged.

[0171] As shown in FIG. 31 and FIG. 32, the second hinge joint 312 can move axially relative to the first hinge joint 35 because the second hinge joint 312 is connected to the first hinge joint 35 by the connecting member 36 and the spacer 39 which are fitted in the track-shaped through hole 312b. For example, the second hinge joint 312 can move leftward along its own axis relative to the first hinge joint 35. Because the connecting member 36 and the spacer 39 are limited in the mounting hole 35a of the first hinge joint 35, the connecting member 36, the spacer 39 and the first hinge joint 35 remain relatively static, so the second hinge joint 312 also moves relative to the connecting member 36 and the spacer 39. Because the spacer 39 has elastic deformation performance, the second hinge joint 312 can be reliably connected to the first hinge joint 35 when the second hinge joint 312 moves axially relative to the first hinge joint 35. The design that the second hinge joint 312 can move axially relative to the first hinge joint 35 facilitates the seamless fit between the second hinge joint 312 and the first hinge joint 35 when the antenna 3 is folded (for example, the state shown in FIG. 32); and when the second hinge joint 312 rotates relative to the first hinge joint 35 to bend the antenna 3, it can also avoid the interference between the second hinge joint 312 and the first hinge joint 35, ensuring smooth rotation. This will be described in more detail below.

[0172] As described above, in another embodiment, the structure of the second hinge joint 312 and the first hinge joint 35 can be adjusted so that they do not interfere with each other when rotating relative to each other, at which time the track-shaped through hole 312b can be set as a circular hole.

[0173] In one embodiment, the electrical connection structure 32 can be a separate component, and the electrical connection structure 32 is connected to the first hinge joint 35 by an assembly process.

[0174] As shown in FIG. 31, the electrical connection structure 32 can include an elastic member 322 and a contact member 321, for example. The elastic member 322 has elastic expansion performance, for example, it can be a spring or the like. The contact member 321 is a rigid component for conducting the elastic force of the elastic member 322. The contact member 321 can be a cylindrical structure with one end open, for example, and the elastic member 322 can be fitted in the inner cavity of the contact member 321.

[0175] As shown in FIG. 33, FIG. 31 and FIG. 29, the electric connection structure 32 can be accommodated in the groove 35d of the first hinge joint 35, wherein the opening of the contact piece 321 can face the bottom wall of the groove 35d, the opposite ends of the elastic piece 322 can abut against the bottom wall of the groove 35d and the contact piece 321 respectively, and the contact piece 321 can be exposed from the opening of the groove 35d. As will be described below, the part of the contact piece 321 exposed from the opening of the groove 35d can abut against the shell of the electronic device, so that the electric connection structure 32 can elastically connect the first hinge joint 35 and the shell of the electronic device. Due to the existence of the elastic piece 322, the electric connection structure 32 can have the performance of elastic expansion and contraction in the radial direction of the first hinge joint 35, and can ensure that the first hinge joint 35 and the shell of the electronic device can be reliably mechanically and electrically contacted during the whole process of the sliding of the first hinge joint 35 relative to the shell of the electronic device, and can also provide a damping feeling.

[0176] As can be understood from the above, under the premise that the contact piece 321 connects the elastic piece 322 and the shell of the electronic device, the structure of the contact piece 321 can be arbitrarily adjusted as needed, and the contact piece 321 is not limited to a cylindrical structure. For example, the contact piece 321 can be designed as a plate-shaped structure, so that the contact piece 321 is connected between the elastic piece 322 and the shell of the electronic device. Alternatively, the contact piece 321 can be cancelled, and the elastic piece 322 is directly used to connect the first hinge joint 35 and the shell of the electronic device.

[0177] In some embodiments of the present application, the groove 35d with a certain depth is formed on the first hinge joint 35 in the radial direction thereof, and the electric connection structure 32 is accommodated in the groove 35d. The internal space of the first hinge joint 35 can be used to accommodate the electric connection structure 32, so that the space outside the first hinge joint 35 is not occupied, which is beneficial to realize the miniaturization of the product. In another embodiment of the present application, the groove 35d can not be provided on the first hinge joint 35, and the electric connection structure can be fixed to the outer peripheral surface of the first hinge joint 35 or the inner wall of the shell of the electronic device. It can be understood that, in order to reliably install the electric connection structure, when the electric connection structure is installed on the first hinge joint 35, a groove can also be formed on the first hinge joint 35, and the electric connection structure is installed in the groove, which can be shallower than the groove 35d described above; when the electric connection structure is installed on the inner wall of the shell of the electronic device, a groove can also be formed on the inner wall of the shell of the electronic device, and the electric connection structure is installed in the groove. The specific structure of the electric connection structure is not limited, for example, it can be in the form of a sheet, a block, a ring, etc., as long as it can connect the first hinge joint 35 and the shell of the electronic device. The electric connection structure can have the performance of elastic expansion and contraction in the radial direction, or can basically have no performance of elastic expansion and contraction in the radial direction.

[0178] As shown in FIG. 31 and FIG. 33, the knob 34 can be installed in the installation slot 35b of the first hinge joint 35, and the arc-shaped or arched end of the knob 34 can be fitted into the installation slot 35b, so that the size of the installation slot 35b can be smaller (compared with a square installation slot), which is beneficial to ensure the structural strength of the first hinge joint 35. As shown in FIG. 33 and FIG. 30, the connecting piece 33 can pass through the through hole 35c on the first hinge joint 35 and the installation hole 34a on the knob 34 to connect them, so as to fix the knob 34 in the installation slot 35b. The knob 34 and the first hinge joint 35 are connected by assembly, which is convenient for realizing the detachable assembly of the antenna 3. In another embodiment, the knob 34 can be assembled by any other suitable method, for example, the knob 34 can be fixed in the installation slot 35b by clamping or welding, or the knob 34 and the first hinge joint 35 can be integrated.

[0179] FIG. 34 shows the perspective structure of the inner rod 37. As shown in FIG. 34, the inner rod 37 can be generally cylindrical. One end of the inner rod 37 can form an external thread 37a for connecting with the connecting head 30. The inner rod 37 can further form a ring-shaped protrusion 37b and a ring-shaped protrusion 37c, which can be located at the end of the inner rod 37 away from the external thread 37a, for example. Both the ring-shaped protrusion 37b and the ring-shaped protrusion 37c can surround the axis of the inner rod 37, and each of the ring-shaped protrusion 37b and the ring-shaped protrusion 37c can form an annular groove 37d therebetween. At least one of the ring-shaped protrusion 37b and the ring-shaped protrusion 37c can be integrally provided on the outer circumferential surface of the inner rod 37 or connected to the outer circumferential surface of the inner rod 37 by an assembly process. In this embodiment, the inner rod 37 is slidably arranged in the barrel 311, the ring-shaped protrusion 37b can serve as an electrical connection structure between the inner rod 37 and the barrel 311, and the annular groove 37d can be used to install the annular ring 38, which will be described below. In another embodiment, the structure of the inner rod 37 can be designed as needed and is not limited to the above description, for example, the inner rod 37 can not be provided with the external thread 37a, the ring-shaped protrusion 37b and / or the ring-shaped protrusion 37c.

[0180] FIG. 35 shows a cross-sectional assembly structure diagram of the antenna 3, which adopts the perspective of FIG. 32. In addition, in order to clearly show the assembly structure of each component, only a part of the components of the antenna 3 is shown in cross-section in FIG. 35. FIG. 36 is a front view of the antenna 3 shown in FIG. 35.

[0181] As shown in FIG. 35 and FIG. 36, the barrel 311 and the second hinge joint 312 of the sleeve 31 can be threadedly connected. The inner rod 37 can be installed in the barrel 311 of the sleeve 31, one end of the inner rod 37 can be exposed from the barrel 311 and threadedly connected with the connecting head 30, and the ring-shaped protrusion 37b and the ring-shaped protrusion 37c of the inner rod 37 can be adjacent to the second hinge joint 312. Neither the ring-shaped protrusion 37b nor the ring-shaped protrusion 37c is in contact with the barrel 311.

[0182] As shown in FIG. 36, the annular ring 38 can be sleeved on the inner rod 37 and located between the annular protrusion 37b and the annular protrusion 37c. The annular ring 38 also contacts the inner wall of the barrel 311. The annular ring 38 can be an insulator and can also have elasticity, which can reliably connect the inner rod 37 and the barrel 311 and provide a damping feel.

[0183] As shown in FIG. 36, the second hinge joint 312 connects the barrel 311 and the first hinge joint 35. The second hinge joint 312 is rotatable with the first hinge joint 35 through the connecting member 36 and the like, which has been described above and will not be repeated here.

[0184] As shown in FIG. 36, the push block 34 can be fixed to the end of the first hinge joint 35 away from the second hinge joint 312. The connection between the push block 34 and the first hinge joint 35 has been described above and will not be repeated here.

[0185] As shown in FIG. 36 and FIG. 33, the electrical connection structure 32 can be accommodated in the groove 35d of the first hinge joint 35, and the part of the contact member 321 of the electrical connection structure 32 exposed from the opening of the groove 35d can abut against the shell of the electronic device, so that the electrical connection structure 32 can elastically connect the first hinge joint 35 and the shell of the electronic device. In the present embodiment, a feed point can be provided on the shell of the electronic device, and the shell can be electrically connected to the communication module through the feed point. Therefore, the antenna 3 can be electrically connected to the communication module through the electrical connection structure 32 and the shell.

[0186] The antenna 3 of the present embodiment can be folded or unfolded along the axial direction. FIG. 36 shows the folded state of the antenna 3, in which the length of the antenna 3 is the shortest, and the second hinge joint 312 and the first hinge joint 35 can be seamlessly connected. From the folded state shown in FIG. 36, the antenna 3 can be gradually unfolded to increase the length and also change the posture. This will be described below.

[0187] Referring to FIG. 36 and FIG. 33, the radio frequency signal fed by the communication module can be fed into the first hinge joint 35, the second hinge joint 312, the barrel 311 and the like in sequence through the electrical connection structure 32 of the antenna 3. The connecting member 30 can be a conductor. In the folded state, the first hinge joint 35, the second hinge joint 312, the barrel 311 and the connecting member 30 all serve as antennas, and the first hinge joint 35, the second hinge joint 312, the barrel 311 and the connecting member 30 can define the length of the antenna; the annular protrusion 37b of the inner rod 37 is located on the right side of the barrel 311, the inner rod 37 is accommodated in the connecting member 30 and the barrel 311, and the inner rod 37 does not contribute to the length of the antenna and can be considered not to be used as an antenna. In another embodiment, the connecting member 30 can be an insulator and not serve as an antenna.

[0188] As shown in FIGS. 36 and 37, the user can pull the inner rod 37 from the connector 30, so that the inner rod 37 slides out of the sleeve 31 to the limit position, so that the antenna 3 is in the first unfolded state shown in FIG. 37. As shown in FIG. 37, in the first unfolded state, the annular protrusion 37b of the inner rod 37 is in contact with the skirt 311a of the barrel 311, so that the inner rod 37 cannot continue to slide out of the sleeve 31, and the inner rod 37 is electrically connected with the barrel 311, and the radio frequency signal can be fed from the barrel 311 to the inner rod 37 and the connector 30. The inner rod 37 extending out of the sleeve 31 increases the length of the antenna, so the inner rod 37 can be used as an antenna. The annular protrusion 37b can be used as an electrical connection structure between the inner rod 37 and the barrel 311. During the sliding process of the inner rod 37 out of the sleeve 31, the annular ring 38 can make the inner rod 37 and the sleeve 31 in reliable mechanical contact, and also provide a damping feel to increase the user experience.

[0189] Compared with the above embodiment in which the recess 14a is formed on the inner rod 14 and the first electrical connection structure 15 is accommodated, the present embodiment uses the annular protrusion 37b as the electrical connection structure between the inner rod 37 and the barrel 311. Since there is no need to form a recess on the inner rod 37, the inner rod 37 does not need to have a large outer diameter, so it is beneficial to make the outer diameter of the inner rod 37 smaller, thereby facilitating the miniaturization of the antenna 3.

[0190] According to product requirements, in another embodiment, the inner rod 37 can also be electrically connected with the sleeve 31 at all times, rather than only when it reaches the first unfolded state. For example, a component similar to the electrical connection structure 32 can be used to connect the inner rod 37 and the sleeve 31; or the annular ring 38 can be made of a conductor to keep the inner rod 37 electrically connected with the sleeve 31 at all times. By keeping the inner rod 37 electrically connected with the sleeve 31 at all times, the length of the antenna 3 can be continuously changed, and the performance of the antenna 3 can be continuously adjusted.

[0191] When the antenna 3 is unfolded, for example, to the first unfolded state shown in FIG. 37, the length of the antenna 3 increases, and the distance from the antenna 3 to the shell of the electronic device can increase, so that the clearance of the antenna 3 increases, and the radiation aperture of the antenna 3 increases. When the user holds the electronic device, or the electronic device is worn on the human body (the electronic device is a wearable device), the distance from the unfolded antenna 3 to the hand or the part of the human body where the electronic device is located can increase, so that the absorption of the antenna signal by the human body decreases, and the hand model decreases. In summary, when the antenna 3 is unfolded, the performance of the antenna 3 can be improved.

[0192] With reference to FIGS. 37 and 38, the user can continue to pull the inner rod 37 in the same direction, so that the inner rod 37 drives the sleeve 31 away from the first hinge joint 35, so that a gap is formed between the second hinge joint 312 and the first hinge joint 35, and the connecting piece 36 moves to the right end of the second hinge joint 312 relative to the second hinge joint 312, so that the antenna 31 is in the second unfolded state shown in FIG. 38. With reference to FIGS. 38 and 31, during the relative sliding of the second hinge joint 312 and the first hinge joint 35, the elastic gasket 39 can ensure reliable contact between the second hinge joint 312 and the first hinge joint 35, and ensure reliable electrical connection between the second hinge joint 312 and the first hinge joint 35, so that the second hinge joint 312 can always receive radio frequency signals from the first hinge joint 35; in addition, a damping feel can also be provided, increasing user experience.

[0193] When the antenna 3 is unfolded, for example, to the second unfolded state shown in FIG. 38, the length of the antenna 3 is further increased, and the distance between the antenna 3 and the shell of the electronic device is further increased, so that the clearance of the antenna 3 is increased, and the radiation aperture of the antenna 3 is increased. When the user holds the electronic device, or the electronic device is worn on the human body (the electronic device is a wearable device), the distance between the unfolded antenna 3 and the hand or the part of the human body where the electronic device is located can be increased, so that the absorption of the human body to the antenna signal is further reduced, and the hand mode is further reduced. In summary, when the antenna 3 is unfolded, the antenna performance of the antenna 3 can be improved.

[0194] With reference to FIGS. 37 and 38, it can be understood that when the user unfolds the antenna 3 from the first unfolded state, but does not reach the second unfolded state, the antenna performance of the antenna 3 can still be improved.

[0195] With reference to FIGS. 38 and 39, the user can also rotate the sleeve 31 relative to the first hinge joint 35, for example, by about 90 degrees or other angles, so that the antenna 3 is in the third unfolded state. The present embodiment does not limit the rotation direction of the sleeve 31, for example, the sleeve 31 can be rotated in the counterclockwise direction, or in the clockwise direction. It can be understood that since a gap has been formed between the second hinge joint 312 and the first hinge joint 35 in the second unfolded state, the second hinge joint 312 and the first hinge joint 35 will not interfere with each other, and the relative rotation of the sleeve 31 and the first hinge joint 35 can be reliably performed.

[0196] When the user holds the electronic device or the electronic device is worn on the human body (the electronic device is a wearable device), in the third unfolded state, the distance between the antenna 3 and the surface of the hand skin or the surface of the skin of the part of the human body where the electronic device is located can be increased, so that the absorption of the antenna signal by the human body is further reduced, and the reduction of the hand model is further reduced, so that the antenna performance of the antenna 3 can be improved. In addition, adjusting the antenna 3 to the third unfolded state can also meet some user needs, such as reducing the space occupation of the antenna 3 or making the antenna 3 avoid in order to be operated by the user on the premise of improving the antenna performance.

[0197] It can be understood that the relative movement between the components of the antenna 3 is bidirectional. For example, referring to FIG. 38, the relative movement between the inner rod 37 and the sleeve 31 is bidirectional, that is, the inner rod 37 can also slide into the sleeve 31, for example, slide to the right in FIG. 38; the relative movement between the sleeve 31 and the first hinge joint 35 is bidirectional, for example, the sleeve 31 can also slide to the right relative to the first hinge joint 35 in FIG. 38.

[0198] As can be easily understood from the foregoing, the antenna 3 of the embodiment can be axially telescoped twice and can also be rotated and bent. By the above-mentioned manner, the antenna 3 can be unfolded, so as to improve the antenna performance and improve the user experience.

[0199] It can be understood that by adjusting the number of inner rods and sleeves in the antenna, the antenna can realize axial telescoping of any order. For example, in another embodiment, the antenna can have multiple inner rods and multiple sleeves, and the sleeves and inner rods are nested in the order of sleeve-inner rod-sleeve-inner rod-…, so as to realize the multiple axial telescoping of the antenna.

[0200] As shown in FIGS. 36-38, during the unfolding of the antenna 3 of the above-mentioned embodiment, the knob 34 can be fixedly arranged, and the remaining components of the antenna 3 can be sequentially elongated to the left. In another embodiment, the inner rod 37 can be fixed, and the remaining components of the antenna 3 can be sequentially elongated to the right. Or in another embodiment, the sleeve 31 can be fixed, and the remaining components of the antenna 3 can be elongated to the left and to the right, respectively.

[0201] As shown in FIG. 39, the sleeve 31 of the antenna 3 of the above-mentioned embodiment can axially move and rotate relative to the first hinge joint 35, and the inner rod 37 can axially move relative to the sleeve 31 but cannot rotate relative to the sleeve 31. Referring to FIG. 39, in another embodiment, the inner rod 37 can axially move relative to the sleeve 31 and rotate relative to the sleeve 31 after extending from the sleeve 31. The specific implementation manner can refer to the above-mentioned embodiment, which will not be repeated here.

[0202] Referring to Fig. 39, in another embodiment, the first hinge joint 35 can be replaced by a first connecting joint, such that the first connecting joint forms an axial sliding connection with the sleeve 31 and the two cannot rotate relative to each other. In this embodiment, the inner rod 37 can move axially relative to the sleeve 31 but cannot rotate relative to the sleeve 31, or the inner rod 37 can both move axially and rotate relative to the sleeve 31.

[0203] In another embodiment, the antenna can have no rotating connection design, and the antenna has no rotating bending function but only axial telescopic function.

[0204] The following will take the above-mentioned antenna 3 as an example to describe the assembly structure of the antenna in an electronic device.

[0205] Figs. 40-45 are schematic diagrams of the assembly structure of the antenna 3 in an electronic device 4. The electronic device 4 can be a smart watch.

[0206] As shown in Fig. 40, in one embodiment, the electronic device 4 can include a main body 41 and the antenna 3, etc.

[0207] The main body 41 is the main structural and functional part of the electronic device 4, and for example, can include a housing 412, a display screen 411 mounted on the housing 412, and the communication module provided in the housing 412, etc. The housing 412 can be provided with a feed point, and the housing 412 can be electrically connected with the communication module through the feed point.

[0208] As shown in Figs. 40 and 42, the housing 412 can be provided with a receiving groove 412a, and the receiving groove 412a can have openings facing different directions. The antenna 3 can be slidably mounted in the receiving groove 412a, and the connecting joint 30 and the knob 34 of the antenna 3 can respectively expose from different openings of the receiving groove 412a. The antenna 3 shown in Fig. 40 is in a folded state, and the connecting joint 30 can be substantially flush with the outer surface of the housing 412, so as to ensure the appearance experience of the electronic device 4; the part of the knob 34 exposed from the opening can be more, so as to facilitate manual operation. Exemplarily, the axis of the antenna 3 can be substantially parallel to the display screen 411.

[0209] As shown in Figs. 40 and 41, the groove wall of the receiving groove 412a can be provided with a through hole 412b, and the contact piece 321 of the electrical connection structure 32 of the antenna 3 can be clamped in the through hole 412b, and the contact piece 321 can abut against the housing 412, so that the antenna 3 can be electrically connected with the communication module through the housing 412.

[0210] For example, the through hole 412b can also be used for mounting the connecting piece 33: as shown in FIGS. 28, 33, 36, 40 and 41, the rest of the components of the antenna 3 except the knob 34 and the connecting piece 33 can be assembled into an assembly in advance, the assembly is placed into the receiving groove 412a, and the through hole 35c on the first hinge joint 35 is aligned with the through hole 412b. Then, the knob 34 is mounted into the mounting groove 35b on the first hinge joint 35, and the connecting piece 33 is inserted into the through hole 412b from one side as shown in FIG. 41 and connected to the knob 34, so that the knob 34 is fixedly connected to the first hinge joint 35. Referring to FIG. 40, after the knob 34 is fixedly connected to the first hinge joint 35, the knob 34 is pushed to the right to reach the innermost part of the receiving groove 412a, at which time the contact piece 321 is clamped in the through hole 412b. As can be seen from the above, the through hole 412b can be used for assembling the antenna 3 and limiting the contact piece 321, and such a design can simplify the product structure and ensure the appearance of the product.

[0211] As shown in FIGS. 40 and 42, the user can push the antenna 3 as a whole out of the receiving groove 412a by operating the knob 34, so that the antenna 3 is exposed from the receiving groove 412a, as shown in FIG. 42. In this process, the antenna 3 is still in the folded state, and the length of the antenna 3 does not increase, but the distance between the antenna 3 and the shell 412 increases, so that the clearance of the antenna 3 increases, and the radiation aperture of the antenna 3 increases, thereby improving the antenna performance of the antenna 3.

[0212] The antenna 3 in FIG. 43 can be in the first unfolded state, i.e., the antenna 3 is axially elongated for the first time. The antenna 3 in FIG. 44 can be in the second unfolded state, i.e., the antenna 3 is axially elongated for the second time. The antenna 3 in FIG. 45 can be in the third unfolded state, i.e., the antenna 3 is further bent by rotation. As shown in FIGS. 40-45 and described above, when the antenna 3 is exposed and unfolded from the receiving groove 412a, the distance between the antenna 3 and the shell 412 of the electronic device 4 increases, so that the clearance of the antenna 3 increases, and the radiation aperture of the antenna 3 increases; when the antenna 3 is in the third unfolded state as shown in FIG. 45, the distance between the antenna 3 and the surface of the hand can increase, so that the absorption of the antenna signal by the human body is further reduced, and the hand model is further reduced, thereby improving the antenna performance of the antenna 3. In addition, adjusting the antenna 3 to the third unfolded state can also meet some user needs, for example, reducing the space occupation of the antenna 3 or avoiding the antenna 3 to facilitate user operation under the premise of improving the antenna performance.

[0213] It is to be understood that the mounting position of the antenna 3 and the angle of the antenna 3 relative to the display screen 411 shown in Figs. 40-45 are merely examples and are not intended to limit the embodiments of the present application. According to product requirements, the antenna 3 can be mounted at any position of the housing 412, and the angle of the antenna 3 relative to the display screen 411 can be any angle, for example, the axis of the antenna 3 can be substantially perpendicular to the display screen 411.

[0214] The housing 412 shown in Figs. 40-45 does not include a head grain, which is merely an example. In another embodiment, the housing 412 can include a housing body and a head grain, one side of the head grain is connected to the housing body, the head grain and the housing body form detachable connection or non-detachable connection, and the other side of the head grain can be connected to a wristband. The head grain can be provided with the accommodation groove 412a described above. The structural space of the housing body is limited, and therefore the antenna 3 can be mounted on the head grain, so that the structural space of the head grain can be used to accommodate the antenna 3, and the housing body can be kept small in size, which is beneficial to realize the miniaturization of the main body 41. It can be considered that the head grain and the antenna 3 constitute a head grain assembly. In another embodiment, the head grain can be provided, and the antenna 3 can be arranged on the housing body.

[0215] Fig. 46 shows a structural schematic view of an antenna 5 in another embodiment, and Fig. 47 is an exploded structural schematic view of the antenna 5 shown in Fig. 46. As shown in Figs. 46 and 47, the antenna 5 can include a first part 53, a second part 52, and a rotating shaft 54, etc.

[0216] As shown in Figs. 46 and 47, the first part 53 can be substantially a long strip plate structure, for example. The opposite ends of the first part 53 in the length direction can be respectively referred to as a first end 53a and a second end 53b. The above structure of the first part 53 is merely an example, and the embodiments of the present application are not limited thereto, for example, the first part 53 can also be a column, etc.

[0217] As shown in Figs. 46 and 47, the second part 52 can be substantially a cylindrical shape, for example. The opposite ends of the second part 52 in the length direction can be respectively referred to as a third end 52e and a fourth end 52f. The rotating shaft 54 can pass through the fourth end 52f and the second end 53b and form a rotating connection therebetween. The third end 52e and the first end 53a are not connected. The above structure of the second part 52 is merely an example, and the embodiments of the present application are not limited thereto, for example, the second part 52 can also be a plate, etc. The rotating connection mode of the second part 52 and the first part 53 is not limited to the above, for example, one of the fourth end 52f and the second end 53b can form a convex shaft, and the other can form a groove, the convex shaft is inserted into the groove and forms a rotating connection.

[0218] As shown in FIG. 47, the second portion 52 can include a side wall 52b and a side wall 52d, and a gap 52c can be formed between the side wall 52b and the side wall 52d. The gap 52c can or can not extend through the second portion 52 along a radial direction of the second portion 52. In an embodiment, the gap 52c does not extend through the second portion 52 along a length direction of the second portion 52, or the length of the gap 52c is less than the length of the second portion 52, such that the side wall 52b and the side wall 52d meet at one end (e.g., the left end in FIG. 47). In an embodiment, the second portion 52 can further include a protrusion 52a, which can be disposed at the third end 52e, for example.

[0219] FIG. 47 illustrates a state where the second end 53b of the first portion 53 is rotated relative to the fourth end 52f of the second portion 52, such that the first portion 53 is unfolded relative to the second portion 52 by a certain angle. In an embodiment, the first portion 53 can be rotated relative to the second portion 52 by any angle. When the first portion 53 is folded relative to the second portion 52, the first portion 53 can be accommodated in the gap 52c. In another embodiment, the second portion 52 is not limited to the structure having the side wall 52b, the side wall 52d, and the gap 52c. For example, the second portion 52 can not form the gap 52c, and the first portion 53 can be connected to the outside of the second portion 52. When the first portion 53 and the second portion 52 are folded, the first portion 53 and the second portion 52 can be stacked.

[0220] In an embodiment, the antenna 5 can be mounted on a housing of an electronic device, and the antenna 5 can be electrically connected to a communication module of the electronic device through the housing.

[0221] In an embodiment, the antenna 5 can be detachably connected to the housing. A user can detach the antenna 5 from an initial position on the housing and fix the antenna 5 to another position on the housing. The antenna 5 can be electrically connected to the other position, so that the antenna 5 can transmit and receive signals. In an embodiment, when the antenna 5 is at the initial position, the antenna 5 can be electrically connected to the housing to transmit and receive signals, or the antenna 5 can not be electrically connected to the housing and only transmit and receive signals when the antenna 5 is connected to the other position. In an embodiment, the third end 52e of the second portion 52 can be positioned and connected to the other position, so that radio frequency signals can be fed into the third end 52e through the housing. As shown in FIGS. 46 and 47, in an embodiment, the antenna 5 can further include a cover plate 51 and a magnet 55. The magnet 55 can be accommodated in the groove 52g of the third end 52e, and the cover plate 51 can cover the opening of the groove 52g and encapsulate the magnet 55 in the groove 52g. The cover plate 51 can encapsulate and protect the magnet 55. When the third end 52e is positioned at the other position on the housing, the magnet 55 can be magnetically attracted to the magnet at the other position, so that the third end 52e can be connected to the other position. The use of magnetic attraction can facilitate the quick mounting and dismounting of the antenna 5. In another embodiment, the third end 52e can be detachably connected to the other position by any suitable means, such as snap connection, interference fit, etc.

[0222] In another embodiment, the antenna 5 forms a non-detachable connection with the housing, and the antenna 5 only works in its installation position.

[0223] The first part 53 of the antenna 5 in this embodiment can rotate relative to the second part 52 to expand or fold the antenna 5. Referring to FIG. 47, when the antenna 5 is expanded, the length of the antenna 5 increases, and the distance between the antenna 5 and the housing of the electronic device can increase, so that the clearance of the antenna 5 increases, and the radiation aperture of the antenna 5 increases. When the user holds the electronic device or the electronic device is worn on the human body (the electronic device is a wearable device), the distance between the expanded antenna 5 and the hand or the part of the human body where the electronic device is located can increase, so that the absorption of the antenna signal by the human body decreases, and the hand model decreases. In summary, when the antenna 5 is expanded, the antenna performance of the antenna 5 can be improved.

[0224] It can be understood that the antenna 5 in the above only includes two parts that can rotate relative to each other, which is only an example. In fact, according to product needs, the antenna 5 can include more parts that can rotate relative to each other, for example, the antenna 5 can include three parts that are connected in sequence and can rotate relative to each other.

[0225] In addition, the antenna 5 in the above can only be expanded or folded by rotating, which is only an example. According to product needs, in another embodiment, the antenna 5 can also be expanded or folded by axial extension and rotation, for example, referring to FIG. 47, the first part 53 can be provided in a sleeve-inner rod assembly structure, and the inner rod can slide relative to the sleeve to cause the first part 53 to axially extend.

[0226] The assembly structure of the antenna in the electronic device will be described below with the antenna 5 shown in FIG. 46 and FIG. 47 as an example.

[0227] FIG. 48-FIG. 49 are schematic diagrams of the assembly structure of the antenna 5 in the electronic device 6. The electronic device 6 can be a smart watch.

[0228] As shown in FIGS. 48 and 49, in an embodiment, the electronic device 6 can include a main body 61 and an antenna 5, etc. The main body 61 is a main structural and functional part of the electronic device 6, and can include, for example, a housing 612, a display screen 611, a cover plate 613, a magnet 614, and a communication module, etc. The display screen 611, the cover plate 613, and the magnet 614 are all mounted on the housing 612, and the cover plate 613 covers the magnet 614. The communication module is disposed in the housing 612. A feed point can be provided on the housing 612, and the housing 612 can be electrically connected to the communication module through the feed point. The antenna 5 is detachably mounted on the housing 612 at an initial position, which is different from the positions of the cover plate 613 and the magnet 614. In the initial position, the axis of the antenna 5 can be substantially parallel to the display screen 611, and the antenna 5 can be substantially accommodated in the housing 612 to ensure the appearance effect of the electronic device 6. In the initial position, the antenna 5 can be electrically connected to or not electrically connected to the housing 612.

[0229] As shown in FIGS. 48 and 49, for example, the housing 612 can include a housing body 612a and a head 612b, one side of the head 612b being connected to the housing body 612a, and the head 612b and the housing body 612a forming detachable or non-detachable connection, and the other side of the head 612b being connectable to a wristband. The structural space of the housing body 612a is limited, and therefore the antenna 5 can be detachably mounted on the head 612b, so that the structural space of the head 612b can be used to accommodate the antenna 5, and the housing body 612a can maintain a small size, which is beneficial to miniaturization of the main body 61. It can be considered that the head 612b and the antenna 5 constitute a head assembly.

[0230] FIG. 50 schematically shows the assembly structure of the antenna 5 and the head 612b. As shown in FIG. 50, the antenna 5 can be accommodated in the head 612b, the cover plate 51 of the antenna 5 can face outward, and the protrusion 52a of the antenna 5 can be exposed to facilitate the user to take out the antenna 5 from the head 612b.

[0231] It can be understood that the provision of the head 612b and the arrangement of the antenna 5 in the head 612b are only examples, and are not a limitation on the embodiments of the present application. In another embodiment, the head 612b can be provided, and the antenna 5 can be arranged in the housing body 612a; or the antenna 5 can be arranged in the housing body 612a, and the head 612b can not be provided.

[0232] As shown in FIG. 48 and FIG. 51, the user can detach the antenna 5 from the initial position on the shell 612, and can unfold the antenna 5, for example, by 180 degrees. Then, the user can position the third end 52e of the antenna 5 at the cover plate 613 on the shell 612, so that the antenna 5 is magnetically attracted to the shell 612. As shown in FIG. 52, when the antenna 5 is connected to the cover plate 613, the antenna 5 can be substantially perpendicular to the display screen 611, and the antenna 5 is electrically connected to the shell 612 for signal transmission and reception.

[0233] As shown in FIG. 52 and described above, when the antenna 5 is unfolded and placed in another position of the electronic device 6, the distance between the antenna 5 and the shell 612 of the electronic device 6 is increased, so that the clearance of the antenna 5 is increased, and the radiation aperture of the antenna 5 is increased; the distance between the antenna 5 and the skin surface of the hand can be increased, so that the absorption of the antenna signal by the human body is further reduced, and the reduction of the hand model is further reduced, and thus the antenna performance of the antenna 5 can be improved.

[0234] An embodiment in which a watch ring of a smart watch is used as an antenna will be described below.

[0235] As shown in FIG. 53, FIG. 54 and FIG. 55, the electronic device 7 can be a smart watch, and the electronic device 7 can include a shell 73, a display screen 71, a watch ring 72, a key assembly 74, a rotating shaft 75, and the like. The display screen 71, the watch ring 72, the key assembly 74 and the rotating shaft 75 can be mounted on the shell 73. The shell 73 can also be provided with a communication module. In an embodiment, the shell 73 can be provided with a feed point, and the shell 73 can be electrically connected to the communication module through the feed point. In another embodiment, the rotating shaft 75 can be provided with a feed point, and the rotating shaft 75 can be electrically connected to the communication module through the feed point.

[0236] As shown in FIG. 56, the shell 73 can be provided with a recess 73a, and the recess 73a is used to mount the key assembly 74.

[0237] As shown in FIGS. 53-55, the bezel 72 can be substantially ring-shaped, which can surround the periphery of the display screen 71. For example, the bezel 72 can have a clamping portion 72a and a hinged portion 72b, which can be located at the two radial ends of the bezel 72, respectively. The clamping portion 72a, for example, can be ring-shaped, which can be used to form a detachable snap connection with the key assembly 74, and can be referred to as a female buckle. The hinged portion 72b, for example, can be substantially cylindrical, which can be used to cooperate with the rotating shaft 75, which can pass through the inner cavity of the hinged portion 72b and be fixed on the housing 73, so as to rotatably connect the bezel 72 and the housing 73. The rotating shaft 75 can be assembled by several components, which can rotate relative to each other to drive the hinged portion 72b and the entire bezel 72 to rotate. The rotating shaft 75 and the clamping portion 72a (or the key assembly 74) can be located at the two radial ends of the bezel 72, respectively. In another embodiment, other components can be used to replace the rotating shaft 75, including but not limited to torsional springs, etc.

[0238] FIGS. 57, 58 and 59 respectively show the assembly structure of the key assembly 74 from different perspectives. As shown in FIGS. 57-59, the key assembly 74 can include a key 741, a resilient member 742 and a connecting member 743, etc. The key 741 can be substantially block-shaped, and a buckle 741a (or a male buckle) can be formed thereon. The key 741 can also be provided with a movable slot 741b, which can be a racetrack-shaped slot, for example. The key 741 can be used to be fitted into the groove 73a. The resilient member 742 can be a spring, for example, and there can be two resilient members 742, which can be installed on the same side of the key 741. The connecting member 743 can be a screw, for example, which can pass through the housing 73 and into the movable slot 741b, so as to limit the key 741, and thus the key 741 can be mounted on the housing 73 (which will be described below). The outer diameter of the connecting portion of the connecting member 743 can be smaller than the length of the movable slot 741b.

[0239] In combination with FIG. 56 and FIG. 55, the key 741 of the key assembly 74 can be fitted into the groove 73a of the housing 73, and the connecting member 743 can pass through the housing 73 and extend into the groove 73a and the movable slot 741b, so that the key 741 can be mounted on the housing 73. The resilient member 742 can be located in the groove 73a, and can elastically abut between the key 741 and the inner wall of the groove 73a.

[0240] In the state shown in FIG. 55, the buckle 741a of the key 741 can be engaged with the clamping portion 72a of the bezel 72, so that the bezel 72 is buckled on the housing 73. Due to the elastic force of the resilient member 742, the buckle 741a will be kept engaged with the clamping portion 72a, so that the bezel 72 is locked on the housing 73.

[0241] Referring to FIG. 55, when the user presses the button 741, for example, pushes the button 741 to the right, the buckle 741a will be separated from the clamping portion 72a, and at this time the bezel 72 is unlocked. After being unlocked, the bezel 72 will be flipped and unfolded by a certain angle relative to the housing 73 under the drive of the rotating shaft 75, as shown in FIG. 60. The angle of the unfolded bezel 72 relative to the housing 73 is not limited, for example, it can be about 90 degrees. When the bezel 72 is unfolded and the user releases the bezel 72, the elastic member 742 can push the button 741 to move reversely to return to the initial position.

[0242] As shown in FIGS. 54 and 60, for example, when the electronic device 7 is normally worn, the button assembly 74 can be located near the 6 o'clock position, and the rotating shaft 75 can be located near the 12 o'clock position. This design makes the button assembly 74 close to the inner side of the arm, which is convenient for the user to operate, and also makes the position of the unfolded bezel 72 conform to the user's habit. It can be understood that in another embodiment, the positions of the button assembly 74 and the rotating shaft 75 can be arbitrarily set as needed.

[0243] Referring to FIGS. 55 and 56, the user can also rotate the unfolded bezel 72 and close it to the housing 73. The clamping portion 72a will push the buckle 741a to move into the groove 73a until the clamping portion 72a and the buckle 741a are clamped again, at which time the bezel 72 is relocked.

[0244] In this embodiment, the bezel 72 can be used as an antenna. As described above, when the housing 73 is provided with a feed point and the housing 73 is electrically connected to the communication module through the feed point, the bezel 72 can be electrically connected to the communication module through the rotating shaft 75, and then the communication module, so that the radio frequency signal can be fed into the bezel 72. Alternatively, when the rotating shaft 75 is provided with a feed point and the rotating shaft 75 is electrically connected to the communication module through the feed point, the bezel 72 can be electrically connected to the communication module through the rotating shaft 75, so that the radio frequency signal can be fed into the bezel 72.

[0245] Referring to FIG. 60, when the bezel 72 is flipped and unfolded, the distance between the bezel 72 and the housing 73 can be increased, so that the clearance of the bezel 72 is increased and the radiation aperture of the bezel 72 is increased. When the electronic device 7 is worn on the human body, the distance between the unfolded bezel 72 and the hand can be increased, so that the absorption of the antenna signal by the human body is reduced and the hand model is reduced. In summary, when the bezel 72 is unfolded, the antenna performance of the bezel 72 can be improved. In addition, by providing the bezel 72 that can be flipped and unfolded, the operation interest can be increased and the user experience can be improved.

[0246] In another embodiment, the structure of the bezel 72 and the button assembly 74 can be adjusted such that they form any other type of detachable connection, not limited to the snap connection described above. In addition, the above solution can also be applied to other electronic devices having a reversible component, i.e., the electronic device can have a reversible component similar to the bezel 72, which is used as an antenna. For example, the electronic device can also be a smart bracelet.

[0247] The following will illustrate an embodiment in which the main body of an electronic device is used as an antenna.

[0248] As shown in FIGS. 61, 62 and 63, the electronic device 8 can be a smart watch, which can include a main body 81, a base 82, a button assembly 83 and a rotating shaft 84, etc.

[0249] The main body 81 is the main structural and functional part of the electronic device 8, which can include, for example, a housing 812, a display screen 811 mounted on the housing 812, and a communication module arranged in the housing 812, etc. For example, a feed point can be arranged on the housing 812, and the housing 812 can be electrically connected to the communication module through the feed point, so that the housing 812 can be used as an antenna. Other components in the main body 81 can also be used as an antenna, for example, a component arranged in the housing 812 can also be used as an antenna, which is also electrically connected to the communication module. It can be understood that a dedicated antenna can also be arranged in the housing 812, which is electrically connected to the communication module. In summary, the main body 81 in this embodiment can be used as an antenna.

[0250] As shown in FIGS. 61 and 62, the housing 812 can have a hinge portion 812a, which can be, for example, a substantially cylindrical structure. The hinge portion 812a is used to cooperate with the rotating shaft 84, which can pass through the inner cavity of the hinge portion 812a and be fixed to the base 82 to rotatably connect the housing 812 and the base 82. The rotating shaft 84 can be assembled by several components, and the components in the rotating shaft 84 can rotate relative to each other and drive the hinge portion 812a and the entire main body 81 to rotate. In another embodiment, other components can be used instead of the rotating shaft 84, including but not limited to torsional springs, etc.

[0251] As shown in FIGS. 64 and 65, the housing 812 can also have a clamping portion 812b, which is, for example, an annular structure, and is used to form a detachable snap connection with the button assembly 83, and the clamping portion 812b can be referred to as a female buckle. The clamping portion 812b and the hinge portion 812a can be located at two ends of the housing 812 (or the main body 81) in the radial direction, respectively. As shown in FIG. 62, the rotating shaft 84 and the button assembly 83 can be located at two ends of the main body 81 in the radial direction, respectively.

[0252] As shown in FIG. 62, the base 82 can have a ring shape, which can be a ring-shaped side wall, or can have a ring-shaped side wall connected with a bottom wall, which can be substantially parallel to the display screen 811. The base 82 can be provided with a recess 82a for mounting the key assembly 74. The base 82 can also have structures for cooperating with the rotating shaft 84, such as two shaft holes. In this embodiment, the base 82 can also be referred to as a housing.

[0253] Referring to FIG. 62, the key assembly 83 can have substantially the same structure as the key assembly 74 described above, for example, the key assembly 83 can also include keys, elastic members, connecting members, and the like. The keys can be formed with buckles (or male buckles), which are used to be fitted into the recess 82a of the base 82, and the buckles are used to form detachable buckle connections with the clamping portions 812b of the housing 812. The elastic members abut the inner wall of the recess 82a and the keys. The connecting members are used to pass through the base 82 and connect with the keys, so that the keys are mounted on the base 82. The structure of the key assembly 83 itself and the assembly structure of the key assembly 83, the base 82 and the housing 812 will not be repeated here.

[0254] In the state shown in FIG. 61, the key assembly 83 is clamped with the clamping portions 812b of the housing 812, so that the main body 81 is locked on the base 82, and the antenna is in a folded state.

[0255] Referring to FIGS. 64 and 65, when the user presses the keys of the key assembly 83, the main body 81 will be unlocked. After unlocking, the main body 81 will be flipped and unfolded to a certain angle relative to the base 82 under the driving of the rotating shaft 84. The angle at which the main body 81 is unfolded relative to the base 82 is not limited, for example, it can be about 70 degrees.

[0256] As shown in FIGS. 64 and 65, for example, when the electronic device 8 is normally worn, the key assembly 83 can be located near the 12 o'clock position, and the hinge portion 812a can be located near the 6 o'clock position. This design makes the display screen 811 in the unfolded main body 81 face the user, which is convenient for the user to watch. It can be understood that in another embodiment, the positions of the key assembly 83 and the hinge portion 812a can be arbitrarily set as needed.

[0257] Referring to FIGS. 64 and 65, the user can also rotate the unfolded main body 81 and close it with the base 82, so that the main body 81 is relocked by the key assembly 83.

[0258] In this embodiment, the main body 81 can be used as an antenna. As described above, the housing 812 can be provided with a feed point, and the housing 812 is electrically connected with the communication module through the feed point, so that the radio frequency signal can be fed into the housing 812.

[0259] Referring to FIG. 65, when the main body 81 is flipped and unfolded, the distance between the main body 81 and the base 82 can be increased, so that the clearance of the main body 81 is increased, and the radiation aperture of the main body 81 is increased. When the electronic device 8 is worn on the human body, the distance between the main body 81 and the hand after the main body 81 is flipped and unfolded can be increased, so that the absorption of the human body to the antenna signal is reduced, and the reduction of the hand model is reduced. In summary, when the main body 81 is unfolded, the antenna performance of the main body 81 can be improved. In addition, by providing the main body 81 that can be flipped and unfolded, the operation interest can be increased, and the user experience can be improved.

[0260] In another embodiment, the structure of the shell 812 and the key assembly 83 can be adjusted, so that the two form other arbitrary types of detachable connection, which is not limited to the above-mentioned snap connection. In addition, the above-mentioned scheme can also be applied to other electronic devices with a flip component, that is, the electronic device can have a flip component similar to the main body 81, which is used as an antenna. For example, the electronic device can also be a smart bracelet.

[0261] 2. Connection assembly

[0262] In the following, a connection assembly in an electronic device will be described, which is used to detachably connect two components in the electronic device. The electronic device can be, for example, a smart watch, a smart bracelet, or the like wearable device.

[0263] FIG. 66 shows an assembly structure of a connection assembly 9 in an embodiment, and FIG. 67 is an exploded structure diagram of the connection assembly 9 in FIG. 66. As shown in FIG. 66 and FIG. 67, the connection assembly 9 can include a cover plate 91, a connecting piece 92, an operating piece 93, a connecting piece 94, and an elastic piece 95, etc. Among them, the cover plate 91, the connecting piece 92, and the connecting piece 94 can each have two.

[0264] As shown in FIG. 66 and FIG. 67, the cover plate 91 can be generally in a flat plate structure. The cover plate 91 can be provided with a through hole 91a for mounting the connecting piece 92. For example, the cover plate 91 can have an arc-shaped side surface, and the arc-shaped side surfaces of the two cover plates 91 can be oppositely arranged, which are used to adapt to one of the components connected by the connection assembly 9. The cover plate 91 is used to cooperate with the operating piece 93 (which will be described below). The above structure and number of the cover plate 91 are only an example, and the embodiment is not limited thereto. For example, only one cover plate can be provided in the connection assembly 9, and a through hole is provided in the cover plate for the operating piece 93 to pass through, so that the two are cooperated. In another embodiment, the connection assembly 9 can not contain the cover plate 91.

[0265] As shown in FIG. 67 and FIG. 68, the operating member 93 can include a key plate 931 and a matching plate 932 protruding from the key plate 931. The key plate 931 can be substantially a flat plate, for example, in an oval shape. The matching plate 932 can protrude from one surface of the key plate 931, and the normal line of the surface can be substantially along the thickness direction of the key plate 931. The matching plate 932 can be in a bent structure, for example. An end of the matching plate 932 away from the key plate 931 can be provided with a clearance groove 932a to avoid the connecting member 92 (to be further described below). The matching plate 932 can have a first inclined surface 932b inclined relative to the surface of the key plate 931, for example, the first inclined surface 932b can be considered to be outwardly inclined relative to the key plate 931. For example, the matching plate 932 can be provided with two matching plates 932 arranged at two ends of the key plate 931, and the two first inclined surfaces 932b are arranged opposite to each other, and the two first inclined surfaces 932b can form a structure similar to an "eight" shape. One first inclined surface 932b is used to form a sliding fit with one connecting member 94 to drive the connecting member 94 to move (to be further described below).

[0266] The above structure of the operating member 93 is only an example, and the embodiment is not limited thereto. For example, in another embodiment, the structure of the matching plate 932 can be adjusted such that the matching plate 932 is not provided with the clearance groove 932a, and the purpose of avoiding the connecting member 92 can also be achieved. In another embodiment, the operating member 93 can be provided with only one matching plate 932 having the first inclined surface 932b (to be further described below). In another embodiment, the operating member 93 can not have the first inclined surface 932b, and the operating member 93 can form any type of connection with the connecting member 94 and drive the connecting member 94 to move (to be further described below).

[0267] As shown in FIG. 69, the connecting member 94 can include a pin shaft 941 and a connecting portion 942 connected with each other. For example, the connecting portion 942 can be substantially a ring structure, or the connecting portion 942 is a ring wall, and the pin shaft 941 can be connected to the outer surface of the connecting portion 942. The connecting portion 942 can be symmetrical or approximately symmetrical about the axis of the pin shaft 941. Part of the inner surface of the connecting portion 942 is inclined, which can be referred to as a second inclined surface 942a. The second inclined surface 942a and the pin shaft 941 can be located at opposite ends of the connecting portion 942, respectively, and the second inclined surface 942a can be considered to be inclined in a direction away from the pin shaft 941. The second inclined surface 942a is used to form a sliding fit with the first inclined surface 932b.

[0268] As shown in FIG. 69, the connecting member 94 can further include a connecting shaft 943, and the connecting shaft 943, the connecting portion 942 and the pin shaft 941 can be connected in sequence, and the connecting shaft 943 can be connected to the outer surface of the connecting portion 942. The connecting shaft 943 is used to cooperate with the elastic member 95.

[0269] The above structure and number of the connecting members 94 are merely examples, and the present embodiment is not limited thereto. For example, in another embodiment, the connecting members 94 can not have the second inclined surfaces 942a, and the connecting members 94 can form any type of connection with the operating member 93 as long as the operating member 93 can drive the connecting members 94 to move (which will be further described below). In another embodiment, the connecting members 94 can not have the connecting shafts 943, and other suitable structures can be used to cooperate with the elastic members 95, such as grooves formed on the connecting members 94 to cooperate with the elastic members 95.

[0270] The elastic members 95 can be elastic components such as springs. The elastic members 95 can have a symmetrical structure. The elastic members 95 can also be referred to as second elastic members.

[0271] In the present embodiment, the connecting assembly 9 can be used to connect the main body and the wristband of a wearable device, and the connecting assembly 9 can also be referred to as an ear assembly, and the connecting members 94 can also be referred to as ears, and the pin shafts 941 can also be referred to as ear pins.

[0272] FIG. 70 is a Y-Y cross-sectional structure schematic view of the connecting assembly 9 shown in FIG. 66, in which the elastic members 95 are not cross-sectioned. As shown in FIGS. 66 and 70, the connecting assembly 9 can have or approximately have a symmetrical structure, and the symmetry plane can be the Y-Y plane.

[0273] As shown in FIG. 70, the two connecting members 94 can be arranged in a spaced manner, the two pin shafts 941 can be arranged in a back-to-back manner, and the two connecting shafts 943 can be arranged in a face-to-face manner. The elastic members 95 can be connected between the two connecting shafts 943, and the elastic members 95 are used to provide elastic restoring force to the two connecting members 94. In the present embodiment, the axis of the two connecting shafts 943 and the center line of the elastic members 95 can be collinear or approximately collinear, and each connecting portion 942 can be symmetrical or approximately symmetrical about the center line of the elastic members 95.

[0274] As shown in FIG. 70, the two cooperating plates 932 of the operating member 93 can be respectively arranged in the inner cavities of the two connecting portions 942, i.e., the two cooperating plates 932 can be respectively arranged on the inner sides of the two annular walls. The first inclined surface 932b and the second inclined surface 942a are in contact in correspondence, and form a sliding connection. The first inclined surface 932b and the second inclined surface 942a in contact can be parallel or approximately parallel. The key plate 931 of the operating member 93 can be located outside the two connecting portions 942.

[0275] As shown in FIG. 70, two cover plates 91 can be respectively located at opposite sides of the operating member 93, and one cover plate 91 can correspondingly match with one matching plate 932 and one connecting member 94, wherein each cover plate 91 is used to be mounted on a first component in the electronic device and covers a part of the corresponding matching plate 932 and a part of the connecting portion 942. One connecting member 92 can correspondingly pass through the through hole 91a of one cover plate 91 and is fixed to the first component, so as to fix the cover plate 91 to the first component and make the whole connecting assembly 9 mounted on the first component (which will be described below). As shown in FIGS. 68 and 70, the avoiding slot 932a on the operating member 93 can avoid the connecting member 92.

[0276] As described above, the connecting assembly 9 can be mounted on the first component in the electronic device. Referring to FIG. 70, two pin shafts 941 are used to be connected to a second component in the electronic device. Thus, the connecting assembly 9 can connect the first component and the second component.

[0277] Referring to FIG. 70, when the user presses the key plate 931, the second inclined surface 942a in contact with each first inclined surface 932b will be extruded, so that the two connecting members 94 move towards each other and compress the elastic member 95, so that the two pin shafts 941 are separated from the second component, thereby separating the first component and the second component. Conversely, when the user no longer presses the key plate 931, under the rebounding action of the elastic member 95, the two connecting members 94 will move away from each other, so that the two pin shafts 941 are restored to be connected to the second component, thereby re-connecting the first component and the second component. Therefore, the connecting assembly 9 can realize the detachable connection of the first component and the second component, and the operation is simple and fast.

[0278] Referring to FIG. 70, by setting the connecting portion 942 as an annular wall, the operating member 93 can move in the inner cavity of the annular wall without interfering with the connecting portion 942.

[0279] As shown in FIG. 70, since the center lines of the two connecting portions 942, the two connecting shafts 943 and the elastic member 95 of the connecting assembly 9 can be collinear, the movement trajectories of the two connecting members 94 and the elastic member 95 can be the same straight line, so that the movement trajectories of the above-mentioned components are relatively stable and are not easy to be deviated. In addition, it also makes the structure of the connecting assembly 9 relatively compact and does not occupy much space, which is beneficial to realize the miniaturization of the connecting assembly 9.

[0280] In another embodiment, the operating member 93 is not limited to the above structure, as long as it can drive the two connecting members 94 to move towards each other. For example, the operating member 93 can be a mechanism composed of multiple components, such as a knob and a connecting rod mechanism, and the user can rotate the knob to drive the connecting rod mechanism to move, so that the connecting rod mechanism drives the two connecting members 94 to move towards each other.

[0281] The application of the connecting assembly 9 in the electronic device will be explained below.

[0282] FIG. 71 shows an exploded structure of the electronic device 100 in an embodiment. As shown in FIG. 71, the electronic device 100 can be a smart watch, and the electronic device 100 can include a main body 101, the connecting assembly 9, a head 102, and the like.

[0283] As shown in FIG. 71, the main body 101 is the main structural and functional part of the electronic device 100, and the main body 101 can include a housing 101b, a display 101a mounted on the housing 101b, and the like. The housing 101b can be provided with two mounting holes 101c, and only one mounting hole 101c is shown in FIG. 71 due to the viewing angle.

[0284] As shown in FIG. 71 and FIG. 72, the head 102 can have a mounting slot 102a, and the inner wall of the mounting slot 102a is provided with two through holes 102c. Exemplarily, the bottom surface of the mounting slot 102a can also be provided with two connecting columns 102b, each of which can be hollow, and the inner surface of each connecting column 102b can be provided with internal threads. The head 102 can be used to mount the connecting assembly 9 and connect to the main body 101 through the connecting assembly 9. The head 102 can also be used to connect the main body 101 and a wristband, which can form a detachable or non-detachable connection with the head 102.

[0285] The structure of the head 102 shown in FIG. 71 and FIG. 72 is only an example, and the structure of the head 102 is not limited in the embodiment. For example, the head 102 can also not have the connecting columns 102b.

[0286] FIG. 73 is a schematic view of the assembled structure of the head 102 and the connecting assembly 9, and FIG. 74 is a schematic view of the Z-Z cross-sectional structure of the assembled structure shown in FIG. 73, wherein the elastic member 95 is not cross-sectioned.

[0287] As shown in FIG. 72 and FIG. 74, the connecting assembly 9 can be installed in the mounting slot 102a of the head grain 102, the two pin shafts 941 can respectively pass through the two through holes 102c and be exposed outside the mounting slot 102a, the two cover plates 91 can be located at the opening of the mounting slot 102a, the two connecting members 92 can be respectively fixed to the two connecting columns 102b, and the key plate 931 can be higher than the cover plates 91. In this way, the two cover plates 91 and the operating member 93 can encapsulate the two connecting members 94 and the elastic member 95 in the mounting slot 102a, and the two cover plates 91 can limit the operating member 93 so that the operating member 93 cannot be separated from the head grain 102, and thus the connecting assembly 9 can be fixed on the head grain 102. In this embodiment, the connecting assembly 9 can be fixed in the head grain 102, and it can be considered that the connecting assembly 9 and the head grain 102 jointly constitute the head grain assembly 103. The head grain 102 in the head grain assembly 103 can also be used to connect the wrist strap, and thus the head grain assembly 103 can be used to connect the main body 101 and the wrist strap.

[0288] FIG. 75 and FIG. 76 respectively show the assembly structure of the head grain assembly 103 and the shell 101b from different perspectives. As shown in FIG. 71, FIG. 73 and FIG. 76, the two pin shafts 941 in the head grain assembly 103 can be respectively inserted into the two mounting holes 101c of the shell 101b, so that the head grain assembly 103 is mounted to the shell 101b. For example, as shown in FIG. 75 and FIG. 76, in order to ensure that the appearance of the electronic device 100 is simple and concise, the key plate 931 and the like in the head grain assembly 103 can be located on the inner side of the electronic device 100, that is, on the side facing away from the display screen 101a.

[0289] As shown in FIG. 73-FIG. 76, when the user presses the key plate 931, the two pin shafts 941 will move towards each other and be separated from the shell 101b, at which time the head grain assembly 103 can be separated from the shell 101b; when the user no longer presses the key plate 931, the two pin shafts 941 will move away from each other and be reconnected to the shell 101b, so that the head grain assembly 103 is reconnected to the shell 101b. The head grain assembly 103 of this embodiment can be quickly and conveniently mounted and dismounted to the main body 101 due to the installation of the connecting assembly 9.

[0290] In another embodiment, the head grain assembly 103 can be quickly mounted and dismounted to the wrist strap, wherein a mounting hole can be formed on the wrist strap, and the pin shaft 941 of the head grain assembly 103 can be detachably connected to the mounting hole on the wrist strap.

[0291] In another embodiment, the connecting assembly 9 can also be fixed to other components of the electronic device 100, such as the main body 101 or the wrist strap, and the like. For example, the connecting assembly 9 can be fixed to the shell 101b of the main body 101, and the connecting assembly 9 connects the head grain 102 or the wrist strap through the pin shaft 941. Alternatively, the connecting assembly 9 can be fixed to the wrist strap, and the connecting assembly 9 connects the head grain 102 or the main body 101 through the pin shaft 941.

[0292] Based on the connecting assembly 9 of the above embodiment, other embodiments of the connecting assembly 9 can be obtained. The following will be described.

[0293] For example, in the first embodiment, referring to FIG. 70 and FIG. 74, the two connecting members 94 in the connecting assembly 9 can be respectively referred to as a first connecting member 94 and a second connecting member 94. The first connecting member 94 can be driven by the operation member 93 to move in a direction that compresses the elastic member 95, i.e., the first connecting member 94 can move towards the second connecting member 94. The operation member 93 does not drive the second connecting member 94, and the operation member 93 can be connected to or not connected to the second connecting member 94. For example, the operation member 93 can be connected to the second connecting member 94, and the mating surfaces of the two can be parallel or approximately parallel to the movement direction of the operation member 93, for example, both of the mating surfaces can be vertical surfaces; or the operation member 93 is not connected to the second connecting member 94. In this embodiment, the second connecting member 94 can be fixedly arranged, or the second connecting member 94 can move towards the first connecting member 94 when being pressed. When the user needs to disassemble the head grain assembly 103, the user can press the operation member 93, so that the pin shaft 941 of the first connecting member 94 is separated from the main body 101 or the wrist strap, at this time the user can tilt the head grain assembly 103 relative to the main body 101 or the wrist strap and remove the pin shaft of the second connecting member 94 from the main body 101 or the wrist strap. When the user needs to assemble the head grain assembly 103, the user can first tilt the head grain assembly 103 relative to the main body 101 or the wrist strap and insert the pin shaft of the second connecting member 94 into the main body 101 or the wrist strap, and then press the operation member 93, so that the pin shaft 941 of the first connecting member 94 is aligned with the mounting hole on the main body 101 or the wrist strap, and then the operation member 93 is released, so that the pin shaft 941 of the first connecting member 94 is connected to the main body 101 or the wrist strap.

[0294] Based on the first embodiment described above, in the second embodiment, the operation member 93 can be fixedly connected to the first connecting member 94, and the movement direction of the operation member 93 can be parallel or approximately parallel to the center line of the elastic member 95. In this embodiment, the operation member 93 can be referred to as a knob, and by pushing the operation member 93, the first connecting member 94 can be driven to move towards the second connecting member 94, so as to realize the assembly and disassembly of the head grain assembly 103.

[0295] Based on the above embodiments, referring to FIG. 70, in a third embodiment, two operation members 93 can be provided, and each operation member 93 is correspondingly matched with a connecting member 94 and drives the connecting member 94 to move.

[0297] In the following, a head grain assembly in an electronic device will be described, which is used to connect a main body and a wristband in a wearable device, such as a smart watch, a smart bracelet, etc.

[0298] As shown in FIGS. 71-74, in one embodiment, the head grain assembly 103 can include a head grain 102 and a connecting assembly 9, which can be the connecting assembly 9 in any of the above embodiments. The head grain 102 can be provided with a mounting groove 102a, and the inner wall of the mounting groove 102a is provided with two through holes 102c. The connecting assembly 9 is arranged in the mounting groove 102a, and the two pin shafts 941 of the connecting assembly 9 can respectively pass through the two through holes 102c and be exposed outside the mounting groove 102a. The exposed pin shafts 941 can be connected with the main body 101 or the wristband. The structure, function and working principle of the head grain assembly 103 of the present embodiment have been described above, and will not be repeated here. The head grain assembly 103 of the present embodiment can be quickly and conveniently assembled with or disassembled from the main body 101 or the wristband due to the installation of the connecting assembly 9.

[0299] Based on the above embodiments, in another embodiment, the head grain assembly can also be provided with an antenna, and the antenna in the head grain assembly can be electrically connected with the main body of the electronic device to realize the antenna function. This will be described in the following.

[0300] FIGS. 77 and 78 show a head grain assembly 200 in another embodiment. As shown in FIGS. 77 and 78, the head grain assembly 200 can include a head grain 202, an electrical connection structure 201, a connecting assembly 9 and an antenna 1 in any of the above embodiments, and the electrical connection structure 201, the connecting assembly 9 and the antenna 1 can be mounted on the head grain 202.

[0301] In an embodiment, as shown in FIG. 77 and FIG. 78, the head grain 202 can include a first carrier 202a and a second carrier 202b, which can be connected by the antenna 1.

[0302] For example, the first carrier 202a can have a structure substantially the same as the head grain 102 described above, and the connecting assembly 9 can be fixed to the first carrier 202a. The detailed structure of the first carrier 202a and the assembly structure of the first carrier 202a and the connecting assembly 9 will not be repeated here. The first carrier 202a can also have a mounting cylinder 202c, which can have a tubular structure with two open ends.

[0303] For example, the second carrier 202b can have a mounting cylinder 202d, for example, two mounting cylinders 202d, which can have a certain spacing and can each have a tubular structure with two open ends. The mounting cylinder 202c can be located between the two mounting cylinders 202d.

[0304] As shown in FIG. 77 and FIG. 78, the antenna 1 can pass through the mounting cylinder 202c and the two mounting cylinders 202d, and the limiting part 12 and the limiting part 11a of the antenna 1 can be located outside the two mounting cylinders 202d. The limiting part 12 and the limiting part 11a can block the movement of the two mounting cylinders 202d along the axis of the antenna 1, thereby limiting the mounting cylinder 202c and the two mounting cylinders 202d, so that the first carrier 202a and the second carrier 202b are connected by the antenna 1. It can be understood that the first carrier 202a and the second carrier 202b can be independently rotated relative to the antenna 1, that is, the rotation of the two does not substantially affect each other.

[0305] In another embodiment, the carriers in the head grain assembly 200 are not limited to two, for example, one or three or more. The connection mode of the antenna 1 and the carriers in the head grain assembly 200 can be set as needed, which is not limited to the above.

[0306] As shown in FIG. 78 and FIG. 79, the electrical connection structure 201 can also be mounted to the first carrier 202a.

[0307] As shown in FIG. 79 and FIG. 80, for example, the first carrier 202a can also be provided with a mounting groove 202f and two mounting holes 202e, which can be respectively arranged at opposite ends of the mounting groove 202f, and the two mounting holes 202e can be not communicated with the mounting groove 202f. The mounting groove 202f and the two mounting holes 202e are used to mount the electrical connection structure 201.

[0308] As shown in FIG. 81 and FIG. 82, for example, the electrical connection structure 201 can include a cover plate 201a, a contact part 201b, a connecting part 201c, and an elastic part 201d, etc.

[0309] As shown in FIG. 82, the cover plate 201a can be a substantially flat plate structure, and a through hole 201e can be formed on the cover plate 201a. For example, two through holes 201e can be formed on the cover plate 201a, and the two through holes 201e can be respectively formed on opposite sides of the through hole 201f. The two through holes 201e are not in communication with the through hole 201f.

[0310] As shown in FIG. 82, the contact member 201b can be a hollow member. For example, the outer surface of the contact member 201b can form a clamping platform structure 201g. For example, two clamping platform structures 201g can be formed on opposite ends of the contact member 201b.

[0311] The connecting member 201c can be a threaded connecting member, and two connecting members 201c can be provided. The elastic member 201d can be a spring or other elastic member, and two elastic members 201d can be provided.

[0312] As shown in FIG. 82 and FIG. 81, the elastic member 201d can be arranged in the inner cavity of the contact member 201b. A portion of the contact member 201b can pass through the through hole 201f of the cover plate 201a, and the clamping platform structure 201g can abut against the cover plate 201a, so that the cover plate 201a can limit the contact member 201b. One connecting member 201c can pass through one through hole 201e of the cover plate 201a.

[0313] As shown in FIG. 82, FIG. 81 and FIG. 80, the contact member 201b and the elastic member 201d can be arranged in the mounting groove 202f of the first carrier 202a, and the elastic member 201d can elastically abut against the bottom wall of the mounting groove 202f and the inner wall of the contact member 201b. The cover plate 201a can cover the opening of the mounting groove 202f. Under the abutting action of the elastic member 201d, the portion of the contact member 201b passing through the through hole 201f of the cover plate 201a can protrude relative to the surface of the cover plate 201a. One connecting member 201c can correspond to one through hole 201e of the cover plate 201a and one mounting hole 202e of the first carrier 202a, so as to fix the cover plate 201a on the first carrier 202a, and the cover plate 201a can encapsulate the contact member 201b and the elastic member 201d in the mounting groove 202f.

[0314] The electrical connection structure 201 mounted on the first carrier 202a can be connected with the main body of the electronic device. The assembly structure of the electrical connection structure 201 and the main body will be described below.

[0315] Fig. 83 shows a schematic structure of the main body 301 of the electronic device 300. The main body 301 is the main structural and functional part of the electronic device 300, and may, for example, include a housing, a display screen mounted on the housing, and the communication module disposed in the housing. The housing can be provided with a feed point, and the housing can be electrically connected to the communication module through the feed point. For example, the housing of the main body 301 can be provided with a recess 301a for accommodating part of the electrical connection structure 201.

[0316] As shown in Figs. 77, 81, 83 and 84, the first carrier 202a of the head grain assembly 200 can be connected to the housing in the main body 301 through the connecting assembly 9. The cover plate 201a and the part of the contact 201b protruding relative to the surface of the cover plate 201a can extend into the recess 301a, and the contact 201b can be in contact with the inner wall of the recess 301a, so that the electrical connection structure 201 is electrically connected to the housing of the main body 301. Since the electrical connection structure 201 is provided with the elastic member 201d, the contact 201b can be in elastic contact with the inner wall of the recess 301a, and when the head grain assembly 200 rotates relative to the housing, the electrical connection structure 201 can be reliably connected to the housing.

[0317] In this embodiment, the antenna 1 is connected to the head grain 202, and the head grain 202 is connected to the housing in the main body 301 through the electrical connection structure 201, and the housing is electrically connected to the communication module, so that the radio frequency signal fed by the communication module can be transmitted to the antenna 1 through the housing, the electrical connection structure 201 and the head grain 202, so that the antenna 1 realizes the antenna function.

[0318] The head grain assembly 200 of this embodiment can keep the main body 301 of the electronic device 300 small in size by installing the antenna 1 in the internal space of the head grain 202, which is conducive to miniaturization; the antenna performance of the electronic device 300 can be improved by providing the expandable antenna 1; and the head grain 202 and the antenna 1 can be quickly and conveniently assembled and disassembled with the main body 301 (or the wrist strap) by providing the connecting assembly 9, which is conducive to maintenance and replacement of the head grain 202 and the antenna 1.

[0319] The second carrier 202b of the head grain assembly 200 can be used to connect the wrist strap. By allowing the second carrier 202b and the first carrier 202a to independently rotate relative to the antenna 1, the influence of the rotation of the second carrier 202b on the position of the first carrier 202a can be reduced, and the reliable connection of the electrical connection structure 201 to the main body 301 can be ensured.

[0320] The above takes the antenna 1 in the head grain assembly 200 as an example, which is not a limitation on the embodiments of the present application. In fact, the antenna in the head grain assembly 200 can be any of the antennas in the above embodiments, for example, it can also be the antenna 3 or the antenna 5, etc.
