In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0029] See also Figures 1 to 4The key assembly 100 of the embodiment of the present application includes a main body 10 and a key rod 20. The main body 10 is used to be rotatably mounted on the housing 201 of the electronic device 200. The main body 10 is formed with a through hole 111 and a receiving groove 121 connected to the through hole 111. The key rod 20 includes a push rod portion 21 and a pressing portion 22 connected to the push rod portion 21. The push rod portion 21 passes through the through hole 111 and can be pressed to move relative to the main body 10. The pressing portion 22 is received in the receiving groove 121.

[0030] In the key assembly 100 of the embodiment of the present application, the key assembly 100 includes a main body 10 and a key stem 20. The main body 10 is rotatably mounted on the housing 201 of the electronic device 200. The main body 10 is formed with a through hole 111 and a receiving groove 121 communicating with the through hole 111. The key stem 20 includes a push rod portion 21 and a pressing portion 22 connected to the push rod portion 21. The push rod portion 21 passes through the through hole 111 and can be pressed to move relative to the main body 10. The pressing portion 22 is received in the receiving groove 121. In this way, a user can press the pressing portion 22 with their finger, causing the key stem 20 to move relative to the main body 10, achieving a press-to-trigger function. Simultaneously, the pressing portion 22 is received in the receiving groove 121. During this movement, the back of the user's hand or palm only contacts the outer portion of the main body 10. Because the main body 10 can only rotate and cannot be pressed, this prevents users from accidentally touching the key stem 20, thereby improving the user experience.

[0031] See also Figure 5 and Figure 6 The electronic device 200 according to the embodiment of the present application includes a housing 201 and the key assembly 100 according to the above embodiment, and the main body 10 is rotatably mounted on the housing 201 .

[0032] In this way, the housing 201 can protect the internal components of the electronic device 200 and prevent external shocks and vibrations from damaging the internal components of the electronic device 200. At the same time, the user can also operate and control the electronic device 200 by rotating the main body 10.

[0033] See also Figure 2 and Figure 5 The electronic device 200 of the embodiment of the present application further includes a trigger key 202 , which is disposed in the housing 201 and opposite to the push rod portion 21 . The push rod portion 21 can be pressed to move relative to the main body 10 to trigger the trigger key 202 .

[0034] In this way, the user can press the pressing portion 22 to move the button rod 20 along the through hole 111 , thereby triggering the trigger button 202 to operate the electronic device 200 .

[0035] Specifically, the button rod 20 is disposed in the through hole 111 and the receiving groove 121 of the main body 10. The main body 10 is mounted on the housing 201 of the electronic device 200. When a user needs to perform a pressing operation, they only need to press the pressing portion 22 with their fingers to cause the button rod 20 to move along the through hole 111, while the main body 10 and the housing 201 do not move relative to each other. In this way, the problem of accidental touch by the user during movement can be avoided. When the user presses the pressing portion 22, the push rod portion 21 can move along the direction of the through hole 111 toward the interior of the housing 201, so that the electronic device 200 triggers the corresponding trigger key 202, causing the trigger key 202 to operate, thereby realizing the operation of the electronic device 200.

[0036] Further, see Figure 2 and Figure 5 The electronic device 200 of the embodiment of the present application also includes a first sensing member 204 and a second sensing member 205. The first sensing member 204 is installed on the main body 10, and the second sensing member 205 is installed in the shell 201 and is arranged opposite to the first sensing member 204. The second sensing member 205 is used to cooperate with the first sensing member 204 to detect the rotation angle of the main body 10.

[0037] In this way, the second sensor 205 in the housing 201 can detect the rotation angle of the first sensor 204, and further detect the rotation angle of the main body 10. The electronic device 200 responds accordingly based on the detected angle change.

[0038] Specifically, the button rod 20 is arranged in the through hole 111 and the accommodating groove 121 of the main body 10, that is, the main body 10 device is arranged on the outside of the button rod 20. The user can rotate the main body 10 with his fingers so that the main body 10 can rotate around the through hole 111, so that the electronic device 200 triggers the corresponding trigger key 202 to operate the electronic device 200. At this time, the button rod 20 can rotate with the main body 10 or not with the main body 10, which is not limited here. For example, the user can adjust the time by rotating the main body 10, or operate a drop-down menu. In this way, the button assembly 100 can realize two input methods: button input and rotation input, making the operation of the electronic device 200 more convenient.

[0039] In the embodiment of the present application, the type of the electronic device 200 is not limited. The electronic device 200 can be a watch head of a smart watch, etc. It only needs to include a housing 201 and the button assembly 100 of the above embodiment to meet various needs.

[0040] See also Figure 7The wearable device 300 of the embodiment of the present application includes a wearing component 301 and the electronic device 200 of the above embodiment. The wearing component 301 is connected to the shell 201, and the wearing component 301 is used to wear the electronic device 200 on the user's limb.

[0041] In this way, the user can wear the wearable device 300 on the body through the wearable component 301, freeing the user's hands. At the same time, the wearable device 300 can also detect the user's physiological parameters at all times and improve the user's quality of life.

[0042] In the embodiment of the present application, there is no limitation on the type of the wearable device 300, and it can be worn on the user. For example, the wearable device 300 can be a smart bracelet or a smart watch to be worn on the wrist or arm. In this case, the wearable component 301 can be in the shape of a ring belt, that is, a watch strap, so that the wearable device 300 can better fit on the user's wrist or arm. For another example, the wearable device 300 can be smart glasses and VR equipment to be worn on the user's head. In this case, the wearable component 301 can be a glasses leg or a helmet, so that the wearable device 300 can better fit on the user's head. In addition, in the embodiment of the present application, the wearable device 300 is not limited to a specific wearing position, and it can meet the needs.

[0043] In one example, the electronic device 200 of the embodiment of the present application can be a smart watch. In this case, the button component 100 can be a component such as the crown of the smart watch, and the wearable component 301 is a watch strap. The user can wear the wearable device 300 on the wrist. Since the pressing portion 22 of the button rod 20 is accommodated in the accommodating groove 121 of the main body 10, when the user does push-ups or rides a bicycle, the arm and palm are almost at 90 degrees, and the back of the user's hand will only rest against the main body 10 and will not directly rest against the pressing portion 22 of the button rod 20, thereby avoiding the problem of accidental touch.

[0044] It is understandable that when the electronic device 200 is a smart watch or a smart bracelet, the user can detect his or her own physiological parameters through the electronic device 200. In a specific embodiment, the wearable electronic device 200 can be used to measure the electrical parameters of the user's body, such as heart rate, electrical activity of the heart, etc. In one embodiment, the user can press the button rod 20 to activate the relevant functional components, detect the user's heart rate changes, and capture the user's electrocardiogram. In another example, the user can adjust the time of the smart watch or set an alarm by rotating the main body 10. When the user wears the smart watch to sleep, the smart watch can also detect the user's sleep state to help the user adjust the sleep time in time.

[0045] In addition, in the embodiments of the present application, the material of the housing 201 is not limited, and the material of the housing 201 may include, but is not limited to, plastic, metal, alloy, etc. At the same time, in the embodiments of the present application, the material of the key assembly 100 is also not limited. In one example, when the electronic device 200 does not require an electrocardiogram function, the key assembly 100 is entirely made of metal or alloy. In another example, when the electronic device 200 requires an electrocardiogram function, the main body 10 may be made of an insulating material such as plastic, or the portion where the main body 10 contacts the housing 201 may be made of an insulating material such as plastic, to avoid electrical short circuits between the key rod 20 and the housing 201.

[0046] It is understandable that in the embodiment of the present application, the number of key assemblies 100 on the electronic device 200 is not limited, and the electronic device 200 may have one, two, or more than two key assemblies 100 to meet various needs.

[0047] See also Figure 2 In some embodiments, the shell 201 is provided with a mounting hole 203, the main body 10 includes a sleeve portion 11 through which the mounting hole 203 is formed and an end cover portion 12 connected to the sleeve portion 11, the sleeve portion 11 is formed with a through hole 111, the end cover portion 12 is formed with a receiving groove 121, and the push rod portion 21 is passed through the sleeve portion 11.

[0048] In this way, the button rod 20 can be assembled on the main body 10, and then the main body 10 can be installed in the mounting hole 203, so that the button rod 20 can move along the direction of the through hole 111, while the main body 10 cannot move along the axial direction of the mounting hole 203, thereby enabling the button assembly 100 to achieve the function of preventing accidental touch.

[0049] Specifically, the push rod 21 can be inserted into the sleeve 11, which in turn can be inserted into the mounting hole 203. The push rod 21 and the sleeve 11 have relatively small cross-sectional areas, allowing the mounting hole 203 to be designed to be relatively small. This improves the waterproof and dustproof properties of the housing 201 while still achieving input functionality. The end cap 12 and the pressing portion 22 have relatively large cross-sectional areas, making it easier for the user to press and turn the knob.

[0050] In the embodiment of the present application, the sleeve portion 11 and the end cover portion 12 can be made of plastic and formed in one piece by a mold; the sleeve portion 11 and the end cover portion 12 can also be made of metal or alloy and formed by welding or the like.

[0051] See also Figure 2 and Figure 4 In some embodiments, a first groove 112 is formed on the outer circumferential surface of the sleeve portion 11 , and the button assembly 100 further includes a first sealing member 40 , which is disposed in the first groove 112 and abuts against the inner wall of the mounting hole 203 .

[0052] In this way, the first seal 40 is arranged in the first groove 112 so that the first seal 40 fills the first groove 112 and abuts against the inner wall of the mounting hole 203, preventing water and dust from the external environment from entering the interior of the shell 201 through the gap between the sleeve portion 11 and the mounting hole 203, and the sealing reliability is higher.

[0053] It can be understood that when the main body 10 is installed in the mounting hole 203, the sleeve portion 11 and the mounting hole 203 can rotate relative to each other, so that there will be a gap between the sleeve portion 11 and the inner wall of the mounting hole 203, and thus a first groove 112 is formed on the outer peripheral surface of the sleeve portion 11, and the first seal 40 is arranged in the first groove 112. When the button assembly 100 is assembled in the mounting hole 203, the first seal 40 can fill the entire first groove 112 and at the same time resist the inner wall of the mounting hole 203, thereby achieving a sealing effect, preventing water and dust from the external environment from entering the interior of the shell 201 through the gap between the sleeve portion 11 and the mounting hole 203.

[0054] In related art, the crown of a smartwatch is typically riveted to the watch case, and the sealing ring is typically installed between the contacting surfaces of the two. Riveting can easily cause wear and even damage to the sealing ring, thus affecting the sealing effect. In the present embodiment, however, a first groove 112 is provided on the sleeve portion 11. After assembly, the first groove 112 is aligned with the inner wall of the mounting hole 203, and the first sealing member 40 is positioned within the first groove 112, abutting against the inner wall of the mounting hole 203. This prevents damage to the first sealing member 40 during assembly or pressing.

[0055] See also Figures 2 to 4 In some embodiments, the button assembly 100 further includes a second sealing member 50 . A second groove 211 is formed on the push rod portion 21 . The second sealing member 50 is disposed in the second groove 211 and abuts against the inner wall of the sleeve portion 11 .

[0056] In this way, the second seal 50 is arranged in the second groove 211 so that the second seal 50 fills the second groove 211 and abuts against the inner wall of the sleeve portion 11, preventing water and dust from the external environment from entering the interior of the shell 201 through the gap between the sleeve portion 11 and the button rod 20, further enhancing the reliability of the seal.

[0057] It can be understood that the button rod 20 and the main body 10 can move relative to each other, so there must be a gap between the button rod 20 and the main body 10. Therefore, a second groove 211 is formed on the outer peripheral surface of the push rod portion 21, and the second seal 50 is arranged in the second groove 211 to abut against the inner wall of the sleeve portion 11. The second seal 50 can fill the entire second groove 211 and at the same time abut against the inner wall of the mounting hole 203, further realizing the sealing effect and preventing water and dust from the external environment from entering the interior of the shell 201 through the gap between the sleeve portion 11 and the mounting hole 203.

[0058] In addition, when the key assembly 100 is assembled in the housing 201 , the gap between the end cover 12 and the housing 201 can be set to 0.04 mm-0.06 mm. For example, the gap between the end cover 12 and the housing 201 can be 0.05 mm.

[0059] In the embodiment of the present application, there is no limit on the number of first seals 40 and second seals 50. The number of first grooves 112 and first seals 40 needs to correspond one to one, and the number of second grooves 211 and second seals 50 also needs to correspond one to one to meet various needs. Preferably, the number of first grooves 112 and first seals 40 in the embodiment of the present application can be one, and the number of second grooves 211 and second seals 50 in the embodiment of the present application can be two.

[0060] In addition, in the embodiment of the present application, there is no limitation on the types of the first sealing member 40 and the second sealing member 50. For example, the first sealing member 40 and the second sealing member 50 can both be silicone sealing rings to meet various requirements.

[0061] See also Figures 2 to 4 In some embodiments, the button assembly 100 further includes an elastic member 30 , which is sleeved on the push rod portion 21 and has two ends of the elastic member 30 abutting against the main body 10 and the pressing portion 22 , respectively.

[0062] In this way, after the user presses the button rod 20 , the elastic member 30 can apply a force to the pressing portion 22 away from the through hole 111 , so that the button rod 20 can be reset under the force of the elastic member 30 .

[0063] Specifically, the push rod portion 21 of the button lever 20 is disposed in the through hole 111. When a user presses the push portion 22, the button lever 20 extends into the housing 201, triggering the corresponding components and causing the electronic device 200 to perform the corresponding action. When the user stops pressing the push portion 22 and releases the force exerted on the push portion 22, the elastic member 30 applies a force to the push portion 22 away from the through hole 111, causing the button lever 20 to return to its original position. In this way, the button lever 20 can move between two positions to implement the button input function.

[0064] In addition, in the embodiment of the present application, the elastic member 30 can be a spring, a spring sheet, a silicone rubber or other elastic components, which has a simple and compact structure and is easy to assemble.

[0065] Further, see Figures 2 to 4 In some embodiments, the button assembly 100 further includes a limiting member 60, and a limiting groove 212 is formed at one end of the push rod portion 21 away from the pressing portion 22. The limiting member 60 is disposed in the limiting groove 212, and the limiting member 60 is used to limit the relative position of the button rod 20 and the main body 10.

[0066] In this manner, the button rod 20 can be assembled on the main body 10 via the stopper 60 and the stopper groove 212. The stopper 60 can limit the relative position of the button rod 20 and the main body 10 to prevent the button rod 20 from falling out of the through hole 111 and the receiving groove 121 under the action of the elastic member 30. The stopper 60 can also limit the position of the button rod 20 so that the outer surface of the pressing portion 22 can be flush with or lower than the outer surface of the end cover portion 12 of the main body 10.

[0067] Specifically, the elastic member 30 is first sleeved on the push rod portion 21, and then the push rod portion 21 is passed through the through hole 111 from one side of the accommodating groove 121, so that the two ends of the elastic member 30 respectively abut the bottom wall of the accommodating groove 121 and the pressing portion 22, and at the same time, the limiting groove 212 can extend from the other end of the through hole 111, and finally the limiting member 60 is set in the limiting groove 212. At this time, the limiting member 60 can abut the end of the sleeve portion 11 away from the end cover portion 12, so that the outer surface of the pressing portion 22 can be flush with the outer surface of the end cover portion 12 of the main body 10 or can be lower than the outer surface of the end cover portion 12 of the main body 10, thereby realizing the function of preventing accidental touch, and also preventing the elastic member 30 from popping the button rod 20 out of the through hole 111. In one example, the limiting member 60 can be clamped in the limiting groove 212, so that the limiting member 60 can simultaneously press against the inner wall of the limiting groove 212 and the end of the sleeve portion 11 away from the end cover portion 12 to prevent the button rod 20 from falling out of the through hole 111 and the accommodating groove 121 under the action of the elastic member 30.

[0068] In addition, the limiting member 60 can be set in the limiting groove 212 by spot welding to prevent the limiting member 60 from falling off from the limiting groove 212 during use, causing the limiting member 60 to fail.

[0069] See also Figures 2 to 4 In some embodiments, the main body 10 further includes an insulating sleeve 70 , which is sleeved on the end cover 12 .

[0070] Thus, when the electronic device 200 has an ECG monitoring function, the insulating sleeve 70 can insulate the main body 10 and the key rod 20 from the housing 201, so that the user can normally perform the ECG monitoring function by touching the key rod 20. In addition, the insulating sleeve 70 is mounted on the end cover 12 so that the user can touch the outer edge of the main body 10, that is, touch the insulating sleeve 70, without directly touching the end cover 12 of the main body 10, and the touch feeling is better.

[0071] Specifically, the outer edge of the insulating sleeve 70 can be formed with lines for user touch, thereby increasing the friction between the user's fingers and the insulating sleeve 70, making it easier for the user to touch and rotate the main body 10. The insulating sleeve 70 can be made of metal or plastic, and there is no limitation here. The insulating sleeve 70 only needs to be wear-resistant and have a good touch feel.

[0072] See also Figures 2 to 4 In some embodiments, the button assembly 100 further includes a fixing member 80, which is formed so as to be sleeved on one end of the sleeve portion 11 away from the end cover portion 12 and can rotate relative to the shell 201 following the main body 10. The fixing member 80 is used to install a first sensing member 204. A second sensing member 205 is also installed in the shell 201. The second sensing member 205 is used to cooperate with the first sensing member 204 to detect the rotation angle of the main body 10.

[0073] In this way, the fixing member 80 is formed with an end that is sleeved on the sleeve portion 11 away from the end cover portion 12 to connect the fixing member 80 and the button rod 20 to install the main body 10 on the shell 201. At the same time, the fixing member 80 and the first sensing member 204 can follow the main body 10 to rotate relative to the shell 201, so that the second sensing member 205 can detect the rotation angle of the main body 10, and then the electronic device 200 can trigger corresponding actions through the rotation angle.

[0074] Specifically, the fixing member 80 is disposed in the housing 201 and can rotate relative to the housing 201. The user can rotate the main body 10 to drive the first sensor 204. At this time, the main body 10, the fixing member 80 and the first sensor 204 can be regarded as one body, and the rotation angle and speed are exactly the same. The second sensor 205 in the housing 201 can detect the rotation angle of the first sensor 204, and then detect the rotation angle of the main body 10. The electronic device 200 responds accordingly based on the detected angle change. For example, the user can adjust the time by rotating the main body 10, or operate a drop-down menu.

[0075] In addition, in some embodiments, the fixing member 80 is formed with a connecting hole 81, which can be a threaded hole. The sleeve portion 11 can be provided with threads, and the sleeve portion 11 can be threadedly connected to the fixing member 80 to install the main body 10 on the shell 201.

[0076] In one embodiment, the first sensing element 204 may be a light-emitting element, and the second sensing element 205 may be a photosensitive element, which can detect the angle of rotation of the light-emitting element. In another embodiment, the first sensing element 204 may be a magnetic ring having multiple magnetic poles, and the second sensing element 205 may be a magnetic sensor, which can detect changes in the magnetic poles and thus detect the angle of rotation of the main body 10. Furthermore, in the embodiments of the present application, the types of the first sensing element 204 and the second sensing element 205 are not limited; they can be selected to meet the requirements.

[0077] See also Figures 2 to 4 In some embodiments, the key assembly 100 further includes a damping member 90 , which is disposed in the accommodating groove 121 and located between the main body 10 and the key rod 20 .

[0078] In this way, the damping member 90 is arranged in the accommodating groove 121 and is located between the main body 10 and the button rod 20, so that a certain damping can be generated between the main body 10 and the button rod 20, thereby improving the feel of rotating the main body 10 or pressing the button rod 20. At the same time, the damping member 90 is wear-resistant to prevent the fingers and the pressing part 22 from wearing the main body 10.

[0079] For example, in some embodiments, a protrusion 1211 may be formed in the receiving groove 121, and a damping member 90 may be disposed between the protrusion 1211 and the inner wall of the receiving groove 121, so that the damping member 90 can move with the main body 10. When the key rod 20 is pressed or the main body 10 is rotated, relative movement can be generated between the main body 10 and the key rod 20. The damping member 90 can hinder the relative movement between the main body 10 and the key rod 20, thereby allowing the user to feel the pressing and rotating feel. The damping member 90 can be made of polyoxymethylene (POM) resin, which makes the damping member 90 have advantages such as wear resistance, good acid and alkali stability, and good thermal stability.
