[0024] The technical solutions in the implementation scheme of the application will be described clearly and completely below in conjunction with the drawings in the implementation scheme of the application.

[0025] See also Figure 1 and Figure 2 The present application provides a shell assembly 200, which includes a key 100. The shell assembly 200 also includes a shell 90. The shell 90 is provided with a key hole 91, and the inner wall of the key hole 91 is provided with a limiting protrusion 92. The key 100 is assembled in the key hole 91 of the shell 90. The key 100 includes a conductive keycap 10, a card plate 20, a conductive elastic member 30 and a conductive key column 40. The conductive keycap 10 cooperates with the key hole 91 and is partially exposed in the key hole 91. The card plate 20 is buckled into the portion of the conductive keycap 10 located in the key hole 91, and a limiting hook 21 is provided at the end of the card plate 20. The limiting hook 21 cooperates with the limiting protrusion 92, and the conductive elastic member 30 connects the card plate 20 and the conductive key column 40 to conduct electricity between the conductive keycap 10 and the conductive key column 40, and allows the conductive keycap 10 to move relative to the conductive key column 40.

[0026] It is understood that the key 100 can be used in electronic devices, which can be terminal devices such as mobile phones, tablets, and laptops, or smart wearable devices such as smart watches, smart headphones, and smart glasses. By pressing the conductive keycap 10, the conductive keycap 10 transmits the pressing torque to the conductive key column 40 via the conductive elastic member 30, so that the conductive key column 40 can trigger the key switch to send a signal to control the electronic device. The hook can hook the limit protrusion 92 to prevent the conductive keycap 10 from separating from the housing 90 through the key hole 91, thereby ensuring the safety of the key 100.

[0027] The card plate 20 is buckled with the conductive keycap 10, and the limiting hook 21 is used for limiting to ensure the limiting requirements of the key 100, and the conductive elastic member 30 is used to connect the card plate 20 and the conductive key column 40, so that the conductive key column 40 and the conductive keycap 10 are conductive to meet the effective conductivity requirements, and the conductive elastic member 30 can enable the conductive keycap 10 to move relative to the conductive key column 40, thereby effectively preventing the conductive keycap 10 from tilting and getting stuck, ensuring that the key 100 is effectively pressed, and thereby improving the effectiveness of the key 100.

[0028] In this embodiment, the conductive keycap 10 has an inner surface 11 and an outer surface 12 opposite to the inner surface 11. The inner surface 11 cooperates with the card plate 20. The outer surface 12 is used for the user to touch and press. When the key 100 is assembled in the shell 90, the outer surface 12 is exposed to the shell 90, or is roughly flush with the appearance surface of the shell 90, so that the outer surface 12 of the conductive keycap 10 can be touched and pressed by the user's fingers. The conductive keycap 10 also has a peripheral side surface 13 connected between the inner surface 11 and the outer surface 12. The peripheral side surface 13 is gap-fitted with the inner side wall of the key hole 91.

[0029] The conductive keycap 10 is made of a conductive material. The conductive keycap 10 serves as a conductive electrode. When the conductive keycap 10 is touched by a user, it can obtain the user's physiological electrical signals, and transmit the physiological electrical signals to the electronic devices inside the electronic device through the conductive elastic member 30 and the conductive key column 40, so as to use the electronic devices to obtain the user's physiological information based on the physiological electrical signals. The physiological information can be electrocardiogram data, electromyogram data, electroencephalogram data, etc. The conductive keycap 10 can be an electrocardiogram electrode, an electromyogram electrode, or an electroencephalogram electrode, etc., that is, when the conductive keycap 10 is touched by a user, it can obtain the user's electrocardiogram signal, electromyogram signal, or electroencephalogram signal, etc. The electronic device inside the electronic device can be an ECG (electrocardiogram) device, an EMG (electromyogram) device, or an EEG (electroencephalogram) device to obtain the user's physiological information.

[0030] This application uses the conductive keycap 10 as an ECG electrode as an example. When the conductive keycap 10 is touched by a user, it can transmit the user's ECG signal to an ECG device inside an electronic device to obtain the user's ECG data. This application is not limited to the conductive keycap 10 as an ECG electrode. The conductive keycap 10 can be any electrode that can transmit the user's physiological electrical signals to the electronic devices inside the electronic device.

[0031] Of course, in other embodiments, the conductive keycap 10 can be configured with a portion of conductive material and a portion of non-conductive material. For example, the main body of the conductive keycap 10 is made of ceramic material, and the outer surface 12, the peripheral side surface 13, and the inner surface 11 of the conductive keycap 10 are provided with a metal coating, and the metal coating extends from the outer surface 12 and the peripheral side surface 13 to the inner surface 11, so that the metal coating is electrically connected to the conductive elastic member 30. When the user touches the metal coating, the user's electrocardiogram signal is transmitted through the conductive elastic member 30 to the conductive key column 40, and ultimately to the ECG device inside the electronic device. For another example, the main body of the conductive keycap 10 is made of plastic material, and the conductive keycap 10 is provided with a metal block embedded in the main body, the metal block partially exposed on the outer surface 12 and the inner surface 11, and the conductive elastic member 30 is in contact with the metal block. When the user touches the conductive keycap 10, they can touch the metal block, so that the metal block transmits the user's electrocardiogram signal through the conductive elastic member 30 to the conductive key column 40, and ultimately to the ECG device inside the electronic device.

[0032] Optionally, the conductive keycap 10 is a long strip-shaped plate, and the conductive keycap 10 is made of metal.

[0033] Specifically, the inner surface 11 of the conductive keycap 10 is provided with a stabilizing boss 14, and the retaining plate 20 is securely abutted against the stabilizing boss 14. Two rivet holes 15 are defined on the end surface of the stabilizing boss 14, facing the outer surface 12. These two rivet holes 15 are used to receive rivets 16, which pass through the retaining plate 20 to secure the retaining plate 20 to the conductive keycap 10. Of course, in other embodiments, the conductive keycap 10 may also be provided with a stabilizing groove on the inner surface 11, and the retaining plate 20 may be provided with a snap-fitting boss that fits within the stabilizing groove to secure the retaining plate 20 to the conductive keycap 10.

[0034] In this embodiment, the card plate 20 is a conductive bent plate. The limiting hook 21 is formed by bending and stamping the end of the card plate 20. There are two limiting hooks 21. The two limiting hooks 21 are respectively arranged at both ends of the length direction of the card plate 20. The part of the card plate 20 between the two limiting hooks 21 abuts against the stabilizing boss 14 and is fixedly connected to the conductive elastic member 30. The two limiting hooks 21 correspond to the two ends of the length direction of the conductive keycap 10, so that the two ends of the length direction of the conductive keycap 10 are effectively limited to prevent the conductive keycap 10 from escaping from the key hole 91. The card plate 20 is provided with a connecting arm 22 between the two limiting hooks 21. The limiting hook 21 is bent relative to the connecting arm 22, and the limiting hook 21 and the connecting arm 22 are integrally arranged. The connecting arm 22 abuts against the side of the conductive keycap 10 facing the conductive key column 40, so that the connecting arm 22 and the conductive keycap 10 are stable. The limiting hook 21 can be elastically bent relative to the connecting arm 22. When installing the card plate 20 in the button hole 91, one of the limiting hooks 21 is pressed against the inner wall of the button hole 91 so that the limiting hook 21 can hook the limiting protrusion 92. Then, by squeezing the limiting hook 21 at the other end to bend and deform the connecting arm 22, the limiting hook 21 at the other end is inserted into the button hole 91 and hooks the limiting protrusion 92. This ensures that the card plate 20 is installed at the bottom of the button hole 91, and the two limiting hooks 21 can hook the limiting protrusion 92 respectively.

[0035] It is understandable that in conventional technical solutions, the key and the housing are assembled together using a snap ring assembly. For example, the housing is provided with a key post hole, the key post of the key passes through the key post hole, and the end of the key post passing through the key post hole is provided with a slot, and the snap ring is engaged in the slot to achieve a stable connection between the snap ring and the key post. By making the outer diameter of the snap ring larger than the inner diameter of the key post hole, the snap ring can be supported on the open end of the key post hole facing the inner side of the frame, preventing the key post from detaching from the key post hole, thereby assembling the key and the frame of the electronic device together. However, since space needs to be provided at the end of the key post for the sealing structure to seal with the key post hole, the combination of the end of the key post and the snap ring is limited, and the difficulty of assembling the snap ring and the key post is increased, and the stability of the key post and the snap ring is easily reduced, thereby reducing the safety of the key. Compared with conventional technologies, the embodiments of the present application adopt a method of buckling the card board 20 with the keycap to increase the stability of the card board 20 and the keycap, and facilitate the assembly of the card board 20 and the keycap. The hook of the card board 20 cooperates with the limiting protrusion 92 to prevent the card board 20 and the keycap from detaching from the key hole 91, thereby ensuring the safety of the key.

[0036] Furthermore, the card board 20 has conductive properties, and the card board 20 can be connected to the conductive keycap 10, and then the conductive elastic part 30 can be connected to the conductive key column 40 through the card board 20, so that the conductive keycap 10 can be connected to the conductive key column 40, and the conductive key column 40 can be connected to the conductive structure inside the electronic device, so that the electronic device can obtain the user's electrocardiogram data through the conductive keycap 10.

[0037] In this embodiment, the conductive elastic member 30 has elastic deformation properties and conductive properties. The conductive elastic member 30 can be composed of one device or a plurality of devices. By utilizing the elastic deformation properties of the conductive elastic member 30, the conductive keycap 10 and the card plate 20 can move relative to the conductive key column 40. When the pressing force received by the conductive keycap 10 is not directly against the conductive key column 40, one end of the conductive keycap 10 will be tilted relative to the frame. Under the elastic deformation of the conductive elastic member 30, the conductive key column 40 will not tilt with the conductive keycap 10, that is, it prevents the conductive key column 40 from being stuck with the key hole 91 of the frame, so that the conductive key column 40 can still effectively slide relative to the frame to trigger the key switch.

[0038] Specifically, the conductive elastic member 30 has two oppositely disposed ends. One end of the conductive elastic member 30 is fixedly connected to the card plate 20 and / or the conductive keycap 10, and the other end is connected to the conductive key column 40. The conductive elastic member 30 can be electrically connected to the conductive keycap 10 via the card plate 20 or directly to the conductive keycap 10. When the conductive keycap 10 is tilted relative to the housing 90, the end of the conductive elastic member 30 connected to the card plate 20 and / or the conductive keycap 10 tilts relative to the other end, allowing the conductive elastic member 30 to absorb bias kinetic energy, ensuring that the conductive key column 40 does not tilt and that the conductive key column 40 still maintains electrical connection with the conductive keycap 10.

[0039] In this embodiment, one end of the conductive key column 40 is fixedly connected to the conductive elastic member 30, while the other end is located away from the conductive elastic member 30. The end of the conductive key column 40 away from the conductive elastic member 30 is used to trigger the key switch and to provide electrical communication with the internal electrocardiogram (ECG) components of the electronic device. A sealing structure is also provided around the conductive key column 40 to ensure that the key 100 is sealed and waterproof and dustproof.

[0040] Specifically, a sealing ring 41 is provided along the circumferential direction at one end of the conductive key column 40 away from the conductive key cap 10, and the outer peripheral side wall of the sealing ring 41 is interference fit with the inner peripheral side wall of the key hole 91. The sealing ring 41 has elastic deformation properties. The sealing ring 41 can effectively prevent water, dust, and impurities from entering the inner side of the frame through the gap between the outer wall of the conductive key column 40 and the inner peripheral side wall of the key hole 91. For example, when the key 100 is applied to an electronic device, the electronic device is a smart watch. The electronic device uses the sealing ring 41 to seal the key column and the inner peripheral side wall of the key hole 91, so that the electronic device can meet the 5ATM waterproof requirement.

[0041] More specifically, a clamping groove 42 is circumferentially formed at one end of the conductive key column 40 away from the conductive elastic member 30. The sealing ring 41 is partially inserted into the clamping groove 42. The sealing ring 41 is detachably connected to the key column 31 to facilitate disassembly and maintenance of the sealing ring 41.

[0042] Optionally, the sealing ring 41 is made of silicone material to increase the elastic sealing performance and friction resistance of the sealing ring 41.

[0043] Optionally, the sealing ring 41 is made of rubber to increase the service life of the sealing ring 41 .

[0044] In one embodiment, Figure 2 As shown, the conductive elastic member 30 is provided with an elastic washer 31 and a deformable conductor 32 . The elastic washer 31 is fixedly connected to the card board 20 and the conductive key column 40 . The deformable conductor 32 is built into the elastic washer 31 and conducts electricity between the conductive key cap 10 and the conductive key column 40 .

[0045] In this embodiment, one end of the elastic gasket 31 is fixedly connected to the card board 20 and / or the conductive keycap 10, and the other end is fixedly connected to the conductive key column 40, and is provided with an inner hole 311 extending from one end to the other end. The deformable conductor 32 is at least partially located in the inner hole 311. By partially accommodating the deformable conductor 32 in the inner hole 311, the deformable conductor 32 is protected and prevented from being damaged. One end of the deformable conductor 32 contacts the conductive key column 40 to conduct with the conductive key column 40, and the other end contacts the card board 20 and / or the conductive keycap 10 to conduct with the conductive keycap 10. When the elastic gasket 31 undergoes elastic deformation, the deformable conductor 32 also deforms accordingly, and the deformable conductor 32 always remains conductive with the conductive key column 40 and the conductive keycap 10. The elastic gasket 31 mainly utilizes elastic deformation properties to ensure that the conductive keycap 10 can tilt relative to the conductive key column 40 after being subjected to a biased pressing force, and can return to its original state after the pressing force is removed. The deformable conductor 32 mainly serves to conduct electricity between the conductive key column 40 and the conductive keycap 10. Regardless of whether the conductive keycap 10 is pressed or not, the conductive key column 40 is connected to the conductive keycap 10 through the deformable conductor 32, so that the conductive keycap 10 can transmit the user's electrocardiogram signal to the electrocardiogram device inside the electronic device. The elastic gasket 31 can be made of an insulating material to insulate and protect the deformable conductor 32 to prevent the deformable conductor 32 from short-circuiting with the external circuit.

[0046] Specifically, a slot 17 is provided on the side of the conductive keycap 10 facing the conductive keypost 40 corresponding to the conductive keypost 40, and a protrusion 23 that is interference fit with the slot 17 is provided on the side of the card plate 20 facing the conductive keycap 10, and an inward-concave groove 24 is formed corresponding to the protrusion 23 on the side away from the conductive keycap 10, and the end of the deformable conductor 32 away from the conductive keypost 40 is at least partially accommodated in the groove 24.

[0047] The card slot 17 is provided on the end face of the stabilizing boss 14 so as to increase the depth of the card slot 17, thereby facilitating the stabilization of the card plate 20 and the conductive keycap 10. The protrusion 23 is formed by a stamping process. The protrusion 23 is inserted into the card slot 17 to have an interference fit with the inner wall of the card slot 17. The card slot 17 can be provided with two inner walls opposite to each other in the length direction of the conductive keycap 10 and two outer walls opposite to each other in the length direction of the card plate 20 of the protrusion 23 to have an interference fit. The card slot 17 can also be provided with four inner walls around it and four outer walls around it around it to have an interference fit. The protrusion 23 is used in conjunction with the card slot 17 to increase the structural strength of the card plate 20 and the conductive keycap 10 near the conductive elastic member 30, thereby facilitating the enhanced stability of the connection between the conductive elastic member 30 and the card plate 20 or / and the conductive keycap 10.

[0048] More specifically, to enhance the connection stability between the card plate 20 and the conductive keycap 10, the conductive keycap 10 is provided with two rivet holes 18. The two rivet holes 18 extend from the end surface of the stabilizing boss 14 toward the outer surface 12 of the conductive keycap 10. The two rivet holes 18 are located on either side of the card slot 17. The key 100 also includes two rivets 16 that pass through the card plate 20 and are interference-fitted with the two rivet holes 18, respectively.

[0049] The rivet hole 18 is close to the end of the conductive keycap 10 so that the two ends of the card plate 20 are respectively fixed to the two ends of the conductive keycap 10. The rivet 16 includes a rivet cap 161 and a rivet column 162 extending from the rivet cap 161. Two through holes are respectively provided at both ends of the connecting arm 22 of the card plate 20 near the two limiting hooks 21. The two through holes can respectively face the two rivet holes 18 of the conductive keycap 10. The rivet column 162 passes through the through hole and is inserted into the rivet hole 18. The outer peripheral side wall of the rivet column 162 is interference fit with the inner peripheral side wall of the rivet hole 18. The rivet cap 161 contacts the outer side of the open end of the through hole, so that the rivet cap 161 and the conductive keycap 10 jointly clamp the connecting arm 22, so that the card plate 20 and the conductive keycap 10 are fixed.

[0050] The key 100 also includes two reset elastic members 50, which are sleeved on the end of the rivet 16 and elastically compressed between the conductive keycap 10 and the bottom of the key hole 91. The reset elastic member 50 is a rectangular spring. One end of the reset elastic member 50 is sleeved on the rivet cap 161, so that the rivet cap 161 can be used to compress and guide the reset elastic member 50, and increase the stability of the reset elastic member 50, the conductive keycap 10 and the card plate 20. The reset elastic member 50 provides an elastic restoring force for the conductive keycap 10 to move away from the bottom of the key hole 91, so that the conductive keycap 10 can automatically reset under the elastic force of the reset elastic member 50 after the pressing force is removed. Of course, in other embodiments, the reset elastic member 50 is any one of a torsion spring, an elastic silicone block or an elastic rubber block.

[0051] In order to increase the conductive stability between the conductive elastic member 30 and the conductive keycap 10, the deformable conductor 32 is at least partially accommodated in the groove 24 to increase the contact area between the deformable conductor 32 and the card board 20 and / or the conductive keycap 10, thereby increasing the stability of the deformable conductor 32 and the card board 20 and / or the conductive keycap 10, as well as the effectiveness of electrical signal conduction.

[0052] More specifically, the end of the deformable conductor 32 away from the conductive key column 40 is inserted into the groove 24, and the end of the elastic washer 31 away from the conductive key column 40 is sleeved on the end of the deformable conductor 32 away from the conductive key column 40. The outer wall of the end of the elastic washer 31 away from the conductive key column 40 abuts the inner wall of the groove 24. The groove 24 is provided with two groove inner side walls 241 opposite to each other in the length direction of the card board 20. The outer wall of the elastic washer 31 abuts the groove inner side wall 241. It can be understood that the length direction of the card board 20 is Figure 2 The two limiting hooks 21 of the middle card plate 20 are in opposite directions. The deformable conductor 32 is roughly columnar. The outer diameter of the deformable conductor 32 is smaller than the distance between the inner side walls 241 of the two grooves, so that one end of the deformable conductor 32 does not extend out of the groove 24. By extending one end of the deformable conductor 32 into the groove 24, the deformable conductor 32 is connected to the card plate 20, and the card plate 20 is connected to the conductive keycap 10, so that the conductive keycap 10 is indirectly connected to the conductive keycap 10. The end of the elastic washer 31 away from the conductive key column 40 extends into the groove 24 to stabilize the elastic washer 31 and the card plate 20. The end of the elastic washer 31 away from the conductive key column 40 is covered around one end of the deformable conductor 32.

[0053] Optionally, the elastic gasket 31 is an elastic silicone ring or a rubber ring.

[0054] Optionally, the deformable conductor 32 is a conductive spring, a conductive spring, a conductive cable, a conductive adhesive, a conductive foam, a conductive mesh or other devices.

[0055] It is understood that the end of the elastic washer 31 extending into the groove 24 can also be connected to the cardboard 20 via adhesive, and the end of the deformable conductor 32 extending into the groove 24 can also be connected to the cardboard 20 via conductive adhesive, so as to further stabilize the deformable conductor 32 and the cardboard 20 while ensuring the conductive performance of the deformable conductor 32 and the cardboard 20. The adhesive bonding the elastic washer 31 to the cardboard 20 can also overflow onto the conductive keycap 10 through the opening in the groove 24 in the width direction of the cardboard 20, so as to further stabilize the elastic washer 31 and the conductive keycap 10. The conductive adhesive bonding the deformable conductor 32 to the cardboard 20 can also overflow onto the conductive keycap 10 through the opening in the groove 24 in the width direction of the cardboard 20, so as to ensure the fixed connection and conductive performance of the deformable conductor 32 to the cardboard 20 and the conductive keycap 10.

[0056] Furthermore, a slot 43 is provided on an end surface of the conductive key column 40 facing the conductive key cap 10 . An end of the deformable conductor 32 away from the conductive key cap 10 is inserted into the slot 43 .

[0057] Specifically, the end of the deformable conductor 32 away from the conductive keycap 10 extends relative to the elastic gasket 31 and is inserted into the slot 43. The outer peripheral side wall of the deformable conductor 32 away from the conductive keycap 10 abuts against the inner peripheral side wall of the slot 43, so that the deformable conductor 32 is fixedly connected to the conductive key column 40, and the contact area between the deformable conductor 32 and the conductive key column 40 is increased to ensure the stability of conductivity. The end face of the elastic gasket 31 away from the conductive keycap 10 tightly abuts against the end face of the conductive key column 40 and is located outside the slot 43. The elastic gasket 31 and the conductive key column 40 can be fixed by glue. The outer diameter of the elastic gasket 31 is roughly equal to the outer diameter of the conductive key column 40, so that the elastic gasket 31 has elastic recovery performance and meets the strength requirements of driving the conductive key column 40 to trigger the key switch.

[0058] Optionally, the elastic washer 31 may be integrally injection-molded with the conductive key column 40 through a two-color mold to increase the stability of the elastic washer 31 and the conductive key column 40 .

[0059] In another embodiment, see Figure 3 ,and Figure 2 The embodiment shown is substantially the same, except that the end of the deformable conductor 32 away from the conductive keypost 40 partially extends out of the groove 24 and contacts the conductive keycap 10 . Figure 3 The cross section of the button 100 shown in FIG is based on the length direction of the vertical card board 20 and parallel to the thickness direction of the card board 20. It can be understood that the length direction of the card board 20 is Figure 2The two limiting hooks 21 of the middle card plate 20 are in opposite directions, and the thickness direction of the card plate 20 is normal to the side of the card plate 20 facing the conductive keycap 10. The card plate 20 has two card plate outer side surfaces 290 that are opposite to each other in the width direction. The width direction of the card plate 20 is perpendicular to the relative directions of the two limiting hooks 21 and parallel to the normal direction of the side of the card plate 20 facing the conductive keycap 10. The groove 24 has two opposite openings 242 in the width direction of the card plate 20, and the openings 242 are adjacent to the card plate outer side surface 290. The card slot 17 has two opposite inner side surfaces 171, and the inner side surfaces 171 are opposite to the card plate outer side surface 290 and there is a gap between them, so that the groove 24 is connected to the card slot 17 through the openings 242. The outer diameter of the deformable conductor 32 is approximately equal to the inner diameter of the elastic washer 31, and the outer wall of the deformable conductor 32 abuts against the inner wall of the elastic washer 31. The outer diameter of the deformable conductor 32 is greater than the distance between the two outer side surfaces 290 of the card board. The deformable conductor 32 is provided with a pin portion 321 that extends out of the groove 24 through the opening 242. The pin portion 321 can be located within the distance between the outer side surface 290 of the card board and the inner side surface 171. The elastic washer 31 and the deformable conductor 32 are both partially accommodated within the groove 24 along the length of the card board 20. A portion of the outer wall of the elastic washer 31, distal to the conductive keycap 10, can contact the inner side surface 171, allowing the elastic washer 31 to engage with the card board 20. Another portion of the outer wall of the elastic washer 31 can also abut against two opposing inner side walls of the groove 24 parallel to the length of the card board 20, allowing the elastic washer 31 to abut against the card board 20. The pin portion 321 abuts against the inner side wall and / or bottom wall of the card board 20, allowing the deformable conductor 32 to partially contact the conductive keycap 10, thereby reducing the electrical resistance between the conductive keycap 10 and the deformable conductor 32. It is understood that the pin portion 321 may also contact the conductive keycap 10 via conductive adhesive to further enhance the connection stability between the deformable conductor 32 and the conductive keycap 10. The end of the elastic washer 31, away from the conductive keypost 40, extends from the openings on both sides of the groove 24 and contacts the inner sidewalls of the retaining slot 17, further enhancing the stability of the elastic washer 31 and the conductive keycap 10.

[0060] In another embodiment, see Figure 4 ,and Figure 2The illustrated embodiment is substantially the same, differing in that the end of the deformable conductor 32 away from the conductive key column 40 extends relative to the elastic washer 31. The outer wall of the end of the deformable conductor 32 extending from the elastic washer 31 abuts the inner wall of the groove 24. The end of the elastic washer 31 away from the conductive key column 40 abuts the cardboard 20 and is located outside the groove 24. Specifically, the outer diameter of the deformable conductor 32 is consistent with the inner diameter of the groove 24, so that the peripheral sidewalls of the deformable conductor 32 fit tightly with the inner wall of the groove 24. The deformable conductor 32 is electrically conductive to the cardboard 20, and the cardboard 20 is electrically conductive to the conductive keycap 10. The outer diameter of the elastic washer 31 is larger than the inner diameter of the groove 24, so that the elastic washer 31 abuts the connecting arm 22 of the cardboard 20. The end of the elastic washer 31 can be secured to the cardboard 20 via adhesive to ensure the stability of the elastic washer 31 and the cardboard 20.

[0061] In another embodiment, see Figure 5 ,and Figure 2 The illustrated embodiment is substantially the same, differing in that the end of the elastic washer 31 facing away from the conductive keycap 10 is inserted into the slot 43 of the conductive keypost 40, while the end of the deformable conductor 32 facing away from the conductive keycap 10 is inserted into the slot 43. Specifically, the end of the deformable conductor 32 facing away from the conductive keycap 10 is inserted into the slot 43, and the end of the elastic washer 31 facing away from the conductive keycap 10 is sleeved over the end of the deformable conductor 32 facing away from the conductive keycap 10. The outer wall of the end of the elastic washer 31 facing away from the conductive keycap 10 abuts the inner wall of the slot 43. The outer diameter of the elastic washer 31 is equal to the inner diameter of the slot 43. The outer sidewall of the end of the elastic washer 31 facing away from the conductive keycap 10 abuts the inner sidewall of the slot 43, thereby securing the elastic washer 31 to the conductive keypost 40. The deformable conductor 32 abuts the bottom of the slot 43, meaning that one end of the deformable conductor 32 and one end of the elastic washer 31 are both pluggably mated with the slot 43.

[0062] In another embodiment, see Figure 6 ,and Figure 2 The illustrated embodiment is substantially the same, differing in that the end of the elastic washer 31 facing away from the conductive keycap 10 is inserted into the slot 43, while the end of the deformable conductor 32 facing away from the conductive keycap 10 abuts against the end face of the conductive keypost 40. Specifically, the slot 43 is an annular hole. The conductive keypost 40 is provided with an abutment boss 439 within the slot 43. The end of the elastic washer 31 inserted into the slot 43 is also sleeved around the side of the abutment boss 439. The slot 43 precisely engages the elastic washer 31, enhancing the stability of the elastic insulation and the conductive keypost 40. The deformable conductor 32 is located outside the slot 43 and abuts against the end face of the abutment boss 439.

[0063] In another embodiment, see Figure 7 ,and Figure 2The illustrated embodiment is substantially the same, differing in that an elastic washer 31 is sleeved over the end of the conductive keypost 40 proximal to the conductive keycap 10, and the end of the deformable conductor 32 distal to the conductive keycap 10 is inserted into a slot 43. Specifically, one end of the conductive keypost 40 is inserted into the elastic washer 31, such that the outer peripheral sidewall of the conductive keypost 40 closely mates with the inner peripheral sidewall of the elastic washer 31, thereby securing the conductive keypost 40 and the elastic washer 31. The outer peripheral sidewall of the end of the deformable conductor 32 distal to the conductive keycap 10 abuts against the inner wall of the slot 43, increasing the contact area between the deformable conductor 32 and the conductive keypost 40 and enhancing stability.

[0064] In another embodiment, see Figure 8 ,and Figure 2 The illustrated embodiment is substantially the same, differing in that the outer wall of the deformable conductor 32, located away from the conductive keycap 10, abuts the inner wall of the slot 43, and the end of the elastic washer 31, located away from the conductive keycap 10, abuts the conductive keypost 40 and is located outside the slot 43. Specifically, one end of the deformable conductor 32 is inserted into the slot 43, so that the outer peripheral sidewall of the end of the deformable conductor 32, located away from the conductive keycap 10, closely mates with the inner peripheral sidewall of the slot 43, and the deformable conductor 32 abuts the bottom of the slot 43, thereby securing the conductive keypost 40 and the deformable conductor 32. The end of the elastic washer 31, located away from the conductive keycap 10, can be adhesively bonded to the end of the conductive keypost 40, located near the conductive keycap 10, to secure the elastic washer 31 to the conductive keypost 40.

[0065] In another embodiment, see Figure 9 ,and Figure 2 The illustrated embodiment is substantially the same, differing in that the inner sidewall of the end of the elastic washer 31 away from the conductive keycap 10 abuts the outer sidewall of the end of the conductive keypost 40 near the conductive keycap 10, and the end of the deformable conductor 32 away from the conductive keycap 10 abuts the end of the conductive keypost 40. Specifically, the elastic washer 31 is sleeved over the end of the conductive keypost 40 near the conductive keycap 10, and the end of the deformable conductor 32 away from the conductive keycap 10 abuts the end face of the conductive keypost 40. One end of the conductive keypost 40 is inserted into the elastic washer 31, so that the outer sidewall of the conductive keypost 40 and the inner sidewall of the elastic washer 31 tightly mate, thereby securing the conductive keypost 40 and the elastic washer 31.

[0066] In another embodiment, see Figure 10 ,and Figure 2The illustrated embodiments are substantially the same, differing in that a plug-in post 49 is provided at the end of the conductive keypost 40 proximate to the conductive keycap 10, a plug-in hole is provided at the end of the deformable conductor 32 distal from the conductive keycap 10, and a resilient washer 31 abuts the conductive keypost 40 and is sleeved onto the plug-in post 49 at the end distal from the conductive keycap 10. Both the resilient washer 31 and the deformable conductor 32 are sleeved onto the plug-in post 49 to increase the contact area between the deformable conductor 32 and the conductive keypost 40, ensuring conductivity between the deformable conductor 32 and the conductive keypost 40. Specifically, the inner diameter of the deformable conductor 32 is approximately equal to the outer diameter of the plug-in post 49, allowing one end of the plug-in post 40 to be inserted into the deformable conductor 32. Furthermore, the resilient washer 31 effectively protects the deformable conductor 32 and secures it to the conductive keypost 40.

[0067] In another embodiment, see Figure 11 ,and Figure 2 The illustrated embodiment is substantially the same, differing in that a boss 19 is provided on the side of the conductive keycap 10 facing the conductive keypost 40, corresponding to the conductive keypost 40. A recessed hole 25 is provided on the side of the retaining plate 20 facing the conductive keycap 10, corresponding to the boss 19. A protruding stud 26 is formed on the side of the retaining plate 20 facing the conductive keycap 10, corresponding to the recessed hole 25. The end of the elastic washer 31 facing away from the conductive keypost 40 is sleeved onto the stud 26. Specifically, the boss 19 is provided on the stabilizing boss 14, and the inner sidewall of the recessed hole 25 tightly mates with the outer sidewall of the boss 19, thereby enhancing the stability of the retaining plate 20 and the conductive keycap 10. The inner sidewall of the elastic washer 31 abuts the outer sidewall of the stud 26, thereby securing the elastic washer 31 to the retaining plate 20. The end of the deformable conductor 32 facing away from the conductive keypost 40 abuts the stud 26, i.e., the deformable conductor 32 is elastically held against the end surface of the stud 26 facing the conductive keypost 40. The deformable conductor 32 can be bonded to the end surface of the boss 26 using conductive adhesive to increase the stability of the deformable conductor 32 to the card board 20 and ensure effective electrical connection between the deformable conductor 32 and the card board 20. Of course, in other embodiments, the end of the deformable conductor 32 away from the conductive key column 40 can also be sleeved onto the boss 26 and abut against the outer wall of the boss 26 to increase the contact area between the deformable conductor 32 and the card board 20. The deformable conductor 32 can also contact the sidewall of the boss 19 to reduce the electrical resistance between the deformable conductor 32 and the conductive keycap 10.

[0068] In another embodiment, see Figure 12 ,and Figure 2The illustrated embodiment is substantially the same, differing in that the deformable conductor 32 passes through the card plate 20 and is electrically connected to the conductive keycap 10. Specifically, the card plate 20 has a through-hole 27 at the bottom of the groove 24. The deformable conductor 32 passes through the through-hole 27 and abuts against the bottom of the card slot 17, allowing the deformable conductor 32 to directly contact the conductive keycap 10. This direct contact between the deformable conductor 32 and the conductive keycap 10 reduces the electrical resistance between the deformable conductor 32 and the conductive keycap 10 and increases the stability of the deformable conductor 32 and the conductive keycap 10.

[0069] In another embodiment, see Figure 13 ,and Figure 2 The embodiments shown are roughly the same, except that the conductive elastic member 30 is provided with a conductive ring 39 and an elastic gasket 38, the elastic gasket 38 is fixedly connected to the card plate 20 and the conductive key column 40, the conductive ring 39 is sleeved on the side of the elastic gasket 38, and conducts the conductive key cap 10 and the conductive key column 40.

[0070] The elastic gasket 38 has elastic deformation performance, and the conductive ring 39 has conductive performance and deformable performance. The material of the elastic gasket 38 can be Figure 2 In the embodiment, the material of the elastic gasket 31 is the same as that of the conductive ring 39. Figure 2 The material of the deformable conductor 32 in the embodiment is the same and will not be described in detail here.

[0071] The end of the conductive ring 39 away from the conductive key column 40 is inserted into the groove 24 and abuts the bottom wall of the groove 24. The end of the elastic gasket 38 away from the conductive key column 40 is inserted into the groove 24 and abuts the bottom wall of the groove 24. The side wall of the elastic gasket 38 away from the conductive key cap 10 abuts the inner wall of the slot 43. The end of the conductive ring 39 away from the conductive key cap 10 abuts the end of the conductive key column 40 near the conductive key cap 10 and is located outside the slot 43. The elastic gasket 38 allows the conductive key column 40 to move relative to the conductive key cap 10 to prevent the conductive key cap 10 from tilting and getting stuck. The conductive ring 39 connects the conductive key column 40 to the conductive key cap 10 via the clamping plate 20, so that when the user touches the conductive key cap 10, the electrocardiogram signal is transmitted to the electrocardiogram device through the key 100.

[0072] It is understandable that Figure 13 The embodiment shown can be considered as Figure 2 The elastic washer 31 and the deformable conductor 32 in the embodiment are interchanged so that Figure 2 The elastic washer 31 forms Figure 13 Elastic gasket 38, Figure 2 The deformable conductor 32 is formed Figure 13 The present application is not limited to the above Figure 2 In the embodiment, the elastic washer 31 and the deformable conductor 32 are interchanged to obtain Figure 13 In the case of the embodiment, for example Figures 3 to 12 In the embodiment, a new embodiment obtained by exchanging the positions of the elastic washer 31 and the deformable conductor 32 is also within the protection scope of the present application.

[0073] It is understandable that in the key 100 provided in the embodiment of the present application, the conductive elastic member 30 can be composed of two components: an elastic washer 31 and a deformable conductor 32. Of course, the conductive elastic member 30 can also be a component that has both conductive properties and elastic properties. For example, the conductive elastic member 30 can be a conductive spring, so as to utilize the conductive spring to connect the conductive key column 40 and the card plate 20, so that the conductive keycap 10 is conductive with the conductive key column 40 and ensures that the conductive keycap 10 can tilt and move relative to the conductive key column 40. The conductive elastic member 30 can also be a conductive spring or an elastically deformable conductive glue. The structural form of the conductive elastic member 30 in the embodiment of the present application is not limited to the above embodiment.

[0074] The key 100 of the embodiment of the present application is not limited to the embodiment described above in which one conductive keycap 10 is connected to one conductive keypost 40 via one conductive elastic member 30. In other embodiments, one conductive keycap 10 may be connected to multiple conductive keyposts 40 via multiple conductive elastic members 30, so that one conductive keycap 10 can trigger multiple key switches and conduct electricity with an electrocardiogram device via multiple conductive keyposts 40 to obtain an electrocardiogram of the user. Of course, one conductive keycap 10 may correspond to multiple conductive keyposts 40, and the conductive elastic member 30 may be provided on one of the conductive keyposts 40 to conduct electricity with the conductive keycap 10, while the other conductive keyposts 40 may be fixedly connected to the conductive keycap 10 via non-conductive elastic members 30.

[0075] See also Figure 14 The housing 90 is provided with a key hole 91 that extends through both the outer and inner surfaces of the housing 90. After the key 100 is assembled in the key hole 91, the conductive keycap 10 is at least partially exposed outside the housing 90. When the conductive keycap 10 is pressed, the conductive keypost 40 at least partially protrudes relative to the inner surface of the housing 90, thereby triggering the key switch located within the housing 90.

[0076] Specifically, the housing 90 is provided with a frame 920, and the key hole 91 is provided in the frame 920. The frame 920 has an outer side surface 921 and an inner side surface 922 opposite the outer side surface 921. The inner side surface 922 encloses a receiving space. The receiving space is used to accommodate various functional components, such as a motherboard, key switches, cameras, sensors, memory, antennas, and the like.

[0077] The frame 920 is further provided with a first end face 923 and a second end face 924 opposite to the first end face 923. The inner side face 922 and the outer side face 921 connect the first end face 923 and the second end face 924. The first end face 923 and the second end face 924 can respectively cooperate with the front structural member and the back structural member of the electronic device, and the front structural member and the back structural member are respectively the structural member facing the user and the structural member facing away from the user when the electronic device is in use. For example, the front structural member is a display screen and the back structural member is a back cover. The first end face 923 and the second end face 924 can both be composed of a combination of flat surfaces and non-flat surfaces, that is, the first end face 923 and the second end face 924 can both be provided with a plurality of recesses and protrusions.

[0078] In this embodiment, the key hole 91 extends from the outer side surface 921 to the inner side surface 922. The inner peripheral side wall of the key hole 91 is roughly matched with the outer peripheral side wall of the conductive keycap 10 to achieve the guidance of the conductive keycap 10 by pressing and sliding relative to the frame 920. The conductive keycap 10 is partially accommodated in the key hole 91 and partially exposed from the key hole 91. When the conductive keycap 10 slides relative to the frame 920 under the pressing force, the conductive keycap 10 can be completely retracted into the key hole 91. The frame 920 is provided with two limiting protrusions 92 on the inner side wall of the key hole 91. The two limiting protrusions 92 are respectively provided on the two inner side walls of the key hole 91 opposite to each other in the direction parallel to the length of the frame 920.

[0079] Specifically, the length direction of the conductive key column 40 is roughly perpendicular to the inner side surface 922 and the outer side surface 921 of the frame 920, so that the conductive key column 40 can receive the pressing force of the conductive keycap 10 and slide relative to the frame 920 in the direction perpendicular to the inner side surface 922 and the outer side surface 921, and the sliding force of the conductive key column 40 can be concentrated on the key switch.

[0080] There is a certain sliding distance between the limiting hook 21 and the conductive keycap 10 , and the limiting protrusion 92 slides within the sliding distance, ultimately achieving effective limiting of the key 100 .

[0081] In this embodiment, the frame 920 is a metal part. The key 100 also includes an insulating sleeve 101 that is sleeved on the side of the conductive keycap 10. The insulating sleeve 101 isolates the conductive keycap 10 from the frame 920. The insulating sleeve 101 is used to isolate the frame 920 from the conductive keycap 10 to prevent the frame 920 from being connected to the conductive keycap 10, thereby preventing the user from accidentally touching the frame 920 and misjudging the user's electrocardiogram data, thereby wasting resources of the electronic device. Optionally, the insulating sleeve 101 can be integrally formed with the conductive keycap 10. The insulating sleeve 101 can be a plastic part. The insulating sleeve 101 can also be a ceramic part.

[0082] It is understood that the housing assembly 200 of the embodiment of the present application is not limited to the embodiment in which the frame 920 is assembled with a single button 100. In other embodiments, the frame 920 may be assembled with multiple buttons 100. The frame 920 may also be provided with a single button 100 and conventional buttons arranged side by side with the button 100, so as to achieve a diversified button structure of the housing assembly 200.

[0083] See also Figure 15 、 Figure 16 、 Figure 17 The present application further provides an electronic device 300, comprising a housing assembly 200 and a conductive spring 70. The conductive spring 70 is fixed within the housing 90 and elastically contacts and electrically connects to the conductive key column 40. The conductive spring 70 is configured to electrically connect to the conductive key cap 10 via the conductive key column 40 and the conductive elastic member 30, ultimately transmitting the user's electrocardiogram (ECG) signals to the ECG device within the electronic device 300.

[0084] It is understandable that the electronic device 300 of the embodiment of the present application is introduced by taking a smart watch as an example, but is not limited to smart watches and can also be other devices. The electronic device 300 can be a wearable device such as a bracelet, glasses, head-mounted device, goggles, etc. that includes the housing assembly 200, and can also be a terminal device such as a mobile phone, tablet computer, laptop computer, etc. that includes the housing assembly 200. The electronic device 300 of the present application can use the conductive keycap 10 to obtain the user's physiological electrical signals and obtain the user's physiological information. The physiological information can be electrocardiogram data, or electromyogram data, or electroencephalogram data, etc. The present application uses the conductive keycap 10 as an example of an ECG electrode, but is not limited to this. The electronic device 300 can obtain the user's ECG data, that is, the conductive keycap 10 can constitute an electrocardiograph (ECG) device.

[0085] Specifically, the conductive spring 70 includes a fixed base 71 and an elastic arm 72 that bends relative to the fixed base 71. The fixed base 71 is fixed within the housing 90 and faces the conductive key column 40. The elastic arm 72 elastically contacts the end of the conductive key column 40 away from the conductive keycap 10, thereby achieving electrical continuity between the conductive spring 70 and the conductive keycap 10. Of course, in other embodiments, the conductive spring 70 can also be fixed to one end of the conductive key column 40 and elastically contact a conductive device within the housing 90.

[0086] In this embodiment, the electronic device 300 further includes a conductive electrode 80 and a conductive assembly 110. The conductive electrode 80 is fixed to the housing 90, with a portion disposed on the outside of the housing 90 and another portion disposed on the inside of the housing 90. The conductive assembly 110 is fixed to the inside of the housing 90 and electrically connects the conductive electrode 80 and the conductive spring 70. The conductive electrode 80 and the conductive keycap 10 jointly contact two parts of the user's body, and utilize the conductive circuit inside the electronic device 300 to form a closed circuit with the user's body, thereby obtaining physiological information of the user. The conductive electrode 80 can be an electrocardiogram electrode, so that the conductive electrode 80 and the conductive keycap 10 jointly obtain the user's electrocardiogram signal, allowing the electronic device 300 to obtain the user's electrocardiogram data.

[0087] Specifically, the housing 90 also includes a rear shell 94 that covers the frame 920. The periphery of the rear shell 94 cooperates with the second end surface 924 of the frame 920. The rear shell 94 is provided with a mounting hole 941 and a back cover 942 assembled in the mounting hole 941. The back cover 942 is an insulating member. Optionally, the back cover 942 is a ceramic member. The conductive electrode 80 is provided on the back cover 942. A portion of the conductive electrode 80 is provided on the outer surface of the back cover 942 to facilitate user contact with the conductive electrode 80, and another portion is provided on the inner surface of the back cover 942 to facilitate conductive connection between the conductive electrode 80 and the conductive key column 40 via the conductive component 110. Optionally, the conductive electrode 80 is a coating layer plated on the back cover 942. Of course, in other embodiments, the rear shell 94 may also be a ceramic member, and the conductive electrode 80 is provided on the rear shell 94. The conductive electrode 80 may also be embedded in the rear shell 94.

[0088] The conductive component 110 is provided with a circuit board 120, and the conductive spring is fixed on the circuit board 120 and is conductively connected to the circuit board 120. The conductive component 110 is also provided with a main board 130 and an electrode circuit board 140. The electrode circuit board 140 extends from one side of the main board 130 and is bent relative to the main board 130. One end of the electrode circuit board 140 away from the main board 130 is electrically connected to the conductive electrode 80. The circuit board 120 extends from a side of the main board 130 away from the electrode circuit board 140. The circuit board 120 is a side key circuit board 120. The circuit board 120 is used to connect the conductive spring 70 to the main board 130 to reduce the closed path from the conductive keycap 10 to the conductive electrode 80, thereby improving the sensitivity of the conductive electrode 80 and the conductive keycap 10 in collecting user physiological signals.

[0089] More specifically, a side key connection portion 121 is provided at one end of the circuit board 120 away from the mainboard 130. A reinforcement structure is provided on the side key connection portion 121 to increase its structural strength, facilitate the attachment of the conductive spring 70 to the side key connection portion 121, and effectively support the conductive spring 70. The electronic device 300 also includes a key switch 150 disposed on the side key connection portion 121. The key switch 150 is opposite the conductive key column 40, so that pressing the conductive keycap 10 drives the conductive key column 40 to trigger the key switch 150.

[0090] The fixed base 71 is provided with a U-shaped ring located on the side of the key switch 150, and the elastic arm 72 extends from the two free ends of the U-shaped ring and is bent relative to the U-shaped ring. The elastic arm 72 is also in the shape of a U-shaped ring. The closed end of the elastic arm 72 is provided with an elastic tongue extending toward the open end of the U-shaped ring. The end of the elastic tongue is directly opposite to the key switch 150, and the elastic tongue elastically contacts the end of the conductive key column 40, so that the elastic arm 72 and the conductive keycap 10 are conductive. The fixed base 71 is isolated from the key switch 150 to prevent the conductive spring 70 from short-circuiting the key switch 150 and to prevent the trigger signal of the key switch 150 from interfering with the conductive spring 70 in transmitting physiological signals.

[0091] Optionally, the fixing base 71 and the circuit board 120 may be fixedly connected via an insulating adhesive to prevent a short circuit between the circuit board 120 and the conductive spring 70 .

[0092] Optionally, the conductive spring 70 may be a metal piece containing silver, magnesium, aluminum, copper or the like.

[0093] It can be understood that the conductive circuit connected to the key switch 150 on the circuit board 120 is routed between the two free ends of the U-shaped arm of the fixed base 71, so that the conductive circuit connected to the key switch 150 avoids the fixed base 71, so that the conductive spring 70 receives the electrical signal of the conductive keycap 10 and transmits the electrical signal independently from the key switch 150, thereby ensuring the accuracy of obtaining physiological information and the accuracy of controlling the key 100.

[0094] During the process of the conductive keycap 10 obtaining the user's electrocardiogram data, the conductive electrode 80 contacts the skin of the user's wrist, and the user's fingers touch the conductive keycap 10, and the conductive keycap 10 can be pressed or not pressed; the conductive keycap 10, the conductive elastic part 30, the conductive key column 40, the conductive spring 70, the conductive component 110, the conductive electrode 80 and the user's body form a closed conductive path, and the conductive keycap 10 and the conductive electrode 80 are combined to contact two non-equipotential parts of the user's body respectively, so that an electrocardiogram potential difference is formed between the conductive keycap 10 and the conductive electrode 80, thereby enabling the electronic device 300 to obtain the user's electrocardiogram data using the electronic devices on the electrode circuit board 140.

[0095] When the key 100 triggers the key switch 150, the user presses the conductive keycap 10 with his finger, and the conductive keycap 10 drives the elastic tongue and the elastic arm 72 to deform through the conductive key column 40, and causes the elastic tongue to contact the key switch 150, and then the key switch 150 sends a signal, finally triggering the key switch 150.

[0096] It is understood that the electronic device 300 of the present application is not limited to the above embodiment in which the conductive electrode 80 is electrically connected to the conductive keycap 10 using the electrode circuit board 140, the main board 130, and the circuit board 120. In other embodiments, the conductive electrode 80 may be electrically connected to the electrode circuit board 140, and the electrode circuit board 140 may be directly electrically connected to the conductive spring 70, and then electrically connected to the conductive keycap 10 via the conductive spring 70 and the conductive keypost 40. The structure of the conductive component 110 that electrically connects the conductive electrode 80 to the conductive keypost 40 is not limited. For example, the conductive component 110 may be provided with a coaxial cable to electrically connect the conductive keypost 40 to the conductive electrode 80, or a structure combining a coaxial cable and a circuit board 120 to electrically connect the conductive electrode 80 to the conductive keypost 40. Alternatively, a circuit conductive structure such as a printed circuit board 120, a board-to-board connector, and a flexible circuit board 120 may be provided to electrically connect the conductive electrode 80 to the conductive keypost 40.

This generates user physiological information based on the electrical signals from the conductive electrode 80 and the conductive keycap 10. It is understood that when two non-equipotential parts of the user's body contact the conductive electrode 80 and the conductive keycap 10, for example, the skin of the user's left wrist contacts the conductive electrode 80 and the finger of the right hand contacts the conductive keycap 10, the conductive electrode 80 and the conductive keycap 10 generate a voltage difference signal. The signal processing chip 160 obtains this voltage difference signal and processes it into physiological data. It is understood that the signal processing chip 160 may be an electrocardiogram chip, which can obtain the user's electrocardiogram voltage difference based on the conductive electrode 80 and the conductive keycap 10 and process the electrocardiogram voltage difference into electrocardiogram data. Of course, the signal processing chip 160 may also be an electromyographic chip or an electroencephalographic chip to process electromyographic signals or electroencephalographic signals.

[0098] In order to facilitate the user to see his or her own physiological information, the electronic device 300 also includes a display screen assembly 170 covering the frame 920, and the periphery of the display screen assembly 170 cooperates with the first end face 923 of the frame 920. The display screen assembly 170 is electrically connected to the mainboard 130, and receives physiological data from the signal processing chip 160 through the mainboard 130, and produces a displayable physiological image based on the physiological data. For example, the display screen assembly 170 can display an electrocardiogram, an electromyogram, or an electroencephalogram, etc. Of course, in other embodiments, the electronic device 300 can transmit the electrocardiogram image to other electronic devices 300 with display functions through communication networks such as Bluetooth, WiFi, 5G, and 4G, so as to display the physiological image using an external electronic device 300 with a display function.

[0099] The above is a preferred embodiment of the application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the application. These improvements and modifications are also considered to be within the scope of protection of the application.
