When a user touches the touch surface 200, the conductive body 20 is used for electrically connecting the user to the circuit board 11, when the user presses the touch surface 200 along the first direction S1, the conductive body 20 is used for electrically connecting the user to the circuit board 11, and the conductive body 20 and the insulating portion 21 are used for sliding in the first direction S1 relative to the device body 10, so that the conductive key assembly 2 is used for implementing a key function. Therefore, when the wearable device 1 is worn on a user and the user contacts the touch surface 200, a loop passing through the user is formed between the contact surface 101 and the touch surface 200, the conductive body 20, the touch surface 200, and the circuit board 11 are conducted by the user, so that the circuit board 11 can be used for detecting bioelectricity of the user, the conductive key assembly 2 can realize a function of an electrode for conducting the user and the circuit board 11, and the conductive key assembly 2 can realize a function of a key when the user presses the touch surface 200 along the first direction S1.

It can be understood that, when the wearable device 1 is worn by a user and the user presses the touch panel 200 along the first direction S1, the bioelectrical information of the user can be detected by the circuit board 11, and the conductive key assembly 2 can perform a key function.

Referring to fig. 2 to 4, in some embodiments, the device body 10 may be a middle frame of the wearable device 1, and because the strength of the middle frame and the function of electromagnetic shielding are required in actual design, or even some designs require the middle frame to have an antenna function, in general, the device body 10 at least partially includes a conductive material, so that the insulating part 21 is fixedly sleeved on at least a portion of the periphery of the conductive body 20 to be connected to the device body 10 through the insulating part 21, thereby achieving an insulating connection between the conductive body 20 and the device body 10, effectively preventing the conductive material in the device body 10 from being communicated with the conductive body 20, and interfering with the current at the conductive body 20, thereby improving the bioelectricity detection accuracy of the wearable device 1.

In some embodiments, the device body 10 may include an insulating inner frame 103 and a conductive outer frame 102, the conductive outer frame 102 is disposed at the periphery of the insulating inner frame 103, the key hole 100 includes a first hole section 100a and a second hole section 100b that are communicated with each other, the first hole section 100a is disposed in the insulating inner frame 103, the second hole section 100b is disposed in the conductive outer frame 102, the circuit board 11 is disposed inside the insulating inner frame 103, an end of the conductive body 20 that is away from the touch surface 200 is located inside the insulating inner frame 103, so that the device body 10 may be made of a conductive material to form an outer frame portion exposed in an external space, so that the conductive outer frame 102 can meet use and design requirements, and meanwhile, conduction of electronic components disposed in the insulating inner frame 103 through the inner frame can be avoided, thereby reducing influence of the insulating inner frame 103 on the electronic components included in the device body 10.

Alternatively, the insulating inner frame 103 may be injection molded inside the conductive outer frame 102, so that the assembly process of the insulating inner frame 103 and the conductive outer frame 102 can be omitted, and the connection stability of the insulating inner frame 103 and the conductive outer frame 102 is high.

In some embodiments, the insulating portion 21 may be formed on at least a portion of the outer periphery of the conductive body 20 by in-mold injection molding, so that the assembling process of the insulating portion 21 and the conductive body 20 can be omitted, and the insulating portion 21 and the conductive body 20 can be connected firmly.

The inventor has found that, since the end of the conductive body 20 away from the touch surface 200 needs to be electrically connected to the circuit board 11, in order to prevent water from entering the inside of the insulating inner frame 103 through the gap between the insulating part 21 and the device body 10, and thus affecting the current at the end of the conductive body 20 away from the touch surface 200, the accuracy of bioelectricity detection of the wearable device 1 is reduced, and the waterproof requirement between the insulating part 21 and the device body 10 is high. Based on this, in some embodiments, the plurality of first protruding strips 22 may be annularly disposed on the outer periphery of the insulating portion 21, in the first direction S1, the plurality of first protruding strips 22 are disposed at intervals, a first setting groove 220 is formed between two adjacent first protruding strips 22, the first setting groove 220 may be provided with a waterproof ring 221, the outer periphery of the waterproof ring 221 is slidably and sealingly connected to the hole wall of the key hole 100 along the first direction S1, so that the insulating portion 21 can be slidably and sealingly connected to the hole wall of the key hole 100, the conductive body 20 can slidably penetrate through the water flowing through the key hole 100 along the first direction S1, and a waterproof function between the insulating portion 21 and the key hole 100 is achieved.

Further, since the waterproof ring 221 is provided separately from the insulating portion 21, when the waterproof ring 221 deteriorates over time and the waterproof sealing performance is degraded, the waterproof sealing performance between the insulating portion 21 and the hole wall of the key hole 100 can be easily restored by replacing the waterproof ring 221.

Alternatively, the first protruding strip 22 may be integrally formed on the insulating portion 21, so that the manufacturing and forming processes of the first protruding strip 22 are simple, and the connection relationship between the first protruding strip 22 and the insulating portion 21 is stable.

Alternatively, the number of the first protruding strips 22 may be greater than two to form a plurality of first setting grooves 220, so that a plurality of waterproof rings 221 can be respectively arranged in the plurality of first setting grooves 220 to further improve the waterproof property between the insulating part 21 and the hole wall of the key hole 100 by increasing the number of the waterproof rings 221, as shown in fig. 2 and 3, the number of the first protruding strips 22 is shown to be three in fig. 2 and 3 to form two first setting grooves 220, and the two waterproof rings 221 are respectively arranged in the two first setting grooves 220.

In some embodiments, the conductive body 20 or the insulating portion 21 may be provided with a second protruding portion 23 on an outer periphery thereof, the second protruding portion 23 is located on one side of the first protruding portions 22 along the first direction S1, a second installation groove 230 is formed on one side of the second protruding portion 23, a stopper 231 is arranged in the second installation groove 230, the stopper 231 may include but is not limited to a snap spring, a snap sheet, and the like, the stopper 231 is located on one side of the key hole 100 facing the inside of the device body 10, and an outer diameter of the stopper 231 is greater than an aperture of the key hole 100, the stopper 231 is configured to abut against the device body 10 to limit at least a portion of the conductive body 20 and the insulating portion 21 from being located inside the device body 10, so as to prevent the conductive body 20 and the insulating portion 21 from sliding away from the device body 10 through the key hole 100 along a second direction S2, wherein the second direction S2 is a direction opposite to the first direction S1, as shown in fig. 2 to 4, and the first direction S1 and the second direction S2 are shown by arrows in fig. 2 to 4. Therefore, in the assembly process of the conductive key assembly 2, the end of the conductive body 20 departing from the touch surface 200 can be passed through the key hole 100 to be arranged inside the insulating inner frame 103, and then the limiting member 231 is installed inside the second arrangement groove 230, so that the end of the conductive body 20 departing from the touch surface 200 is limited inside the insulating inner frame 103, on one hand, the assembly step of the conductive key assembly 2 is simple and convenient, and on the other hand, the structural stability of the assembled conductive key assembly 2 is good.

Alternatively, when the second protruding strip 23 is disposed on the insulating portion 21, the second protruding strip 23 may be integrally formed on the insulating portion 21, and when the second protruding strip 23 is disposed on the conductive body 20, the second protruding strip 23 may be integrally formed on the conductive body 20, so that the manufacturing and forming processes of the second protruding strip 23 are simple, and the connection relationship between the second protruding strip 23 and the insulating portion 21 is stable.

Alternatively, the second protruding strip 23 may be disposed at an end of the conductive body 20 away from the touch surface 200, so that the space occupied by the portion of the conductive body 20 located inside the device body 10 is smaller, so as to make the overall structure of the wearable device 1 more compact.

It can be understood that, since the end of the conductive body 20 away from the touch surface 200 is located inside the insulating inner frame 103, in other words, there is no additional insulation requirement between the end of the conductive body 20 away from the touch surface 200 and the insulating inner frame 103, even if the position-limiting member 231 comprises a conductive material, the position-limiting member 231 can be disposed in the second disposition groove 230 formed in the conductive body 20, so that the position-limiting member 231 can abut against the insulating inner frame 103 to achieve the position-limiting function.

In an alternative embodiment, the second setting groove 230 may be formed between the second protruding strip 23 and the adjacent first protruding strip 22, so that the first protruding strip 22 can be structurally reused, so as to make the structure of the conductive key assembly 2 more compact.

In another alternative embodiment, the second protruding strips 23 may include two second protruding strips 23, the two second protruding strips 23 are both disposed around the outer periphery of the conductive body 20, and the two second protruding strips 23 are disposed at intervals along the first direction S1, the second setting groove 230 is formed between the two second protruding strips 23, and since the two second protruding strips 23 are both disposed on the conductive body 20, the two second protruding strips 23 may both be made of the same material as the conductive body 20 and are integrally formed with the conductive body 20, so that the fixing acting forces applied by the two second protruding strips 23 to the limiting member 231 disposed in the second setting groove 230 are balanced, and the stability of the limiting member 231 is better in the using process.

In order to make the end of the conductive body 20 away from the touch surface 200 electrically connected to the circuit board 11 when the conductive body 20 and the insulating part 21 slide in the first direction S1 integrally relative to the apparatus body 10, in some embodiments, the end of the conductive body 20 away from the touch surface 200 may be electrically connected to the circuit board 11 through a conductive member 24, and the conductive member 24 may include, but is not limited to, an elastic sheet, a spring, a flexible circuit board, or other conductive structure capable of deforming.

When the conductive element 24 includes an elastic sheet or a spring, optionally, the conductive element 24 may have a first end 240 and a second end 241 opposite to each other, the first end 240 is disposed on the circuit board 11 and electrically connected to the circuit board 11, and the second end 241 abuts against an end of the conductive body 20 away from the touch surface 200 along the second direction S2, so that on one hand, when the conductive body 20 slides relative to the apparatus body 10 along the first direction S1 or the second direction S2, the second end 241 is kept in abutment against an end of the conductive body 20 away from the touch surface 200, so that the conductive element 24 is kept electrically connected to the conductive body 20, and on the other hand, an elastic force applied by the second end 241 to the conductive body 20 along the second direction S2 may be used as a restoring force, so that after the conductive body 20 is pressed and slides along the first direction S1, the conductive body 20 is pushed by the conductive element 24 to push the conductive body 20 to integrally slide the insulating part 21 along the second direction S2 to reset.

It should be noted that the aforementioned "abutting" of one to another includes a case where one abuts against another and one is at least partially fixedly connected to another, and a case where one abuts against another and one is movably connected to another.

Optionally, when the conductive member 24 is an elastic piece, the first end 240 may have a thickness h1, and the second end 241 may have a thickness h2, and the respective thicknesses of the first end 240 and the second end 241 may satisfy: h1 is greater than h2, so that the structural rigidity of the first end 240 is less than that of the second end 241, when the conductive body 20 slides in the first direction S1 or the second direction S2, the elastic deformation of the conductive member 24 at the first end 240 is greater than that at the second end 241, so that the acting force applied to the joint between the second end 241 and the circuit board 11 due to the elastic deformation of the second end 241 is smaller, and the connection stability between the second end 241 and the circuit board 11 is better.

Optionally, the first end 240 may also be connected to the insulating inner frame 103, so as to further reduce the elastic deformation occurring at the first end 240 by the restraining and fixing action of the first end 240 of the pair of insulating inner frames 103, thereby further improving the connection stability between the first end 240 and the circuit board 11.

Illustratively, the insulating inner frame 103 may further include a connection protrusion 103a, and the first end 240 may further include a connection hole 240a, the connection protrusion 103a extending into the connection hole 240a, so that the first end 240 is sleeved on the outer circumference of the connection protrusion 103a, thereby further restraining and fixing the first end 240 by the connection protrusion 103 a.

In some embodiments, the conductive body 20 may include a first conductive segment 201 and a second conductive segment 202, the first conductive segment 201 has a touch surface 200, the second conductive segment 202 is fixedly connected to the first conductive segment 201 and slidably disposed through the key hole 100 along the first direction S1, an insulating portion 21 is sleeved on the peripheries of the first conductive segment 201 and at least a portion of the second conductive segment 202, and an outer diameter of the first conductive segment 201 is greater than an outer diameter of the second conductive segment 202, so that an area of the touch surface 200 can be increased, and a user can touch and press the touch surface 200 by aligning with the touch surface 200.
