Referring to fig. 1, a wearable electronic device 1000 is provided in an embodiment of the present application. The wearable electronic device 1000 includes an electronic device 100 and a wearing piece 200. The wearing member 200 is connected to the electronic device 100. The electronic apparatus 100 is a functional body of the wearable electronic apparatus 1000. The wearing member 200 may be a connection structure for wearing the electronic device 100 to a wearing body, such as a bracelet, a ring, a spectacle frame, or the like.

The electronic device 100 may be fixedly attached to the wearing piece 200, or the electronic device 100 may be detachably attached to the wearing piece 200.

The present embodiment specifically describes the structure of the electronic device 100 by taking the example that the electronic device 100 can detect an electrocardiogram. Of course, the electronic device 100 may also be configured with reference to the embodiment when being used to detect other feature information, which also belongs to the protection scope of the present application.

The electronic device 100 includes an electrocardiogram detector. The electrocardiogram detector comprises one or more detection electrodes and a signal acquisition circuit connected with the detection electrodes.

The detection electrode is made of a conductive material, and the material of the detection electrode includes, but is not limited to, metal oxide, graphene, conductive graphite, conductive carbon black, single-walled carbon nanotube and multi-walled carbon nanotube. The metal may be in the form of metal nanowires, metal nanoparticles, or metal oxide nanoparticles in the detection electrode. The metal component includes, but is not limited to, gold, silver, copper, aluminum, nickel, or the like. The metal oxide composition includes, but is not limited to, Indium Tin Oxide (ITO) or fluorine doped tin oxide (FTO).

With the electronic apparatus 100 of the present embodiment, which detects an electrocardiogram, the number of the detection electrodes of the electronic apparatus 100 is at least three.

These detection electrodes may be provided on the outer surface of the housing of the electronic device 100. When the wearable electronic apparatus 1000 is worn by a subject (i.e., the wearing body described above), the detection electrodes contact the detection site of the subject to detect the electrocardiogram of the subject. Take wearable electronic device 1000 as an example of a smart watch. The electronic device 100 is a watch face of a watch, and the wearing piece 200 is a watch band of the watch. The dial can be divided into round, square, curved surface, special-shaped and the like according to the shape. The present embodiment is illustrated with the dial being square.

For convenience of description, the length direction of the electronic apparatus 100 is defined as the Y-axis direction, the width direction of the electronic apparatus 100 is defined as the X-axis direction, and the thickness direction of the electronic apparatus 100 is defined as the Z-axis direction.

Referring to fig. 2, the electronic device 100 includes a housing frame 1. Alternatively, the housing frame 1 may be a side frame of the electronic device 100. Specifically, referring to fig. 3 and 4, the electronic device 100 further includes a top case 2 and a bottom case 3 disposed opposite to each other, and the case frame 1 is connected between the top case 2 and the bottom case 3. The top case 2, the case frame 1 and the bottom case 3 enclose a housing chamber 101 forming a hermetic or near hermetic seal. The receiving chamber 101 receives a circuit board, a sensor, a battery, and other components. In other words, the top case 2, the case frame 1, and the bottom case 3 form an integral housing of the electronic apparatus 100.

Referring to fig. 3, when the wearable electronic device 1000 is worn by the detected person, the wrist surface of the detected person contacts the bottom case 3 of the electronic device 100. In this embodiment, the number of the detection electrodes 300 may be three. Of course, three are merely examples, and the number of the detection electrodes 300 is not limited. Alternatively, two detection electrodes 300 are disposed on the outer surface of the bottom case 3, and another detection electrode 300 is disposed on the outer surface of the case frame 1, and this embodiment will be described later. In other alternative embodiments, two detection electrodes 300 are provided on bottom case 3, and another detection electrode 300 is provided on top case 2. The two detection electrodes 300 provided on the bottom chassis 3 are independent of each other, i.e., the two detection electrodes 300 do not directly contact each other. When the subject wears the wearable electronic device 1000, the two detection electrodes 300 on the bottom case 3 are always in contact with the skin of the subject. The two detection electrodes 300 on the bottom shell 3 extend from the outer surface of the bottom shell 3 to the receiving cavity 101, and are connected with the signal acquisition circuit in the receiving cavity 101. The other sensing electrode 300 is also connected to the signal acquisition circuit of the housing 101.

When the wearable electronic device 1000 is worn by the left hand of the subject, both of the detection electrodes 300 contact the left hand of the subject, which is merely an example and does not limit the wearing position of the wearable electronic device 1000. The conducting loop at this time is: detection electrode 300 on left hand-bottom shell 3-signal acquisition circuit. When the right hand of the detected person touches or presses the detection electrode 300 on the housing frame 1, the conductive loop at this time is: right hand-detection electrode 300 on housing frame 1-signal acquisition circuitry. The signal acquisition circuit acquires the voltage difference between the left hand and the right hand and then forms an electrocardiogram waveform according to the voltage difference. Of the two detection electrodes 300 on the housing, one detection electrode 300 may be a driving electrode for enhancing the anti-interference capability of the signal acquisition circuit.

Optionally, the housing frame 1 described herein may also be an integral housing of the electronic device 100. In other words, key assembly 4 of electronic device 100 described herein may be located in top case 2, bottom case 3, or a side case.

Alternatively, the housing frame 1 may also be a combined housing formed by integrally forming the bottom housing 3 and the side housing of the electronic device 100, in other words, the key assembly 4 of the electronic device 100 described herein may be located on the bottom housing 3 or the side housing.

The following description will exemplify a specific structure of the electronic device 100 with reference to the drawings.

Referring to fig. 4 and 5, the electronic device 100 includes a housing frame 1, a key assembly 4 and a circuit assembly 5.

In the present embodiment, referring to fig. 5 and fig. 6, the housing frame 1 is a side housing. The housing frame 1 has an inner cavity 102 and a first through hole 103. The first through hole 103 communicates the inner cavity 102 with an external space 400 outside the housing frame 1. In other words, the housing frame 1 includes an annular inner surface 104 and an annular outer surface 105 which are oppositely disposed. The space enclosed by the inner surface 104 is an inner cavity 102 of the housing frame 1. When electronic device 100 has top case 2 and bottom case 3, an inner cavity 102 is formed by the surface of top case 2 facing bottom case 3, annular inner surface 104 of case frame 1, and the surface of bottom case 3 facing top case 2. The outer space 400 is a space of the annular outer surface 105 of the housing frame 1 facing away from the annular inner surface 104. Alternatively, the inner surface 104 of the case frame 1 may include a flat surface, a curved surface, an uneven surface, or the like. The outer surface 105 of the housing frame 1 may include a plane, a curved surface, an uneven surface, etc., and the housing frame 1 may be an independent structure formed by one material, or a composite structure or a spliced structure formed by multiple different materials through processes such as pressing, injection molding, etc.

Referring to fig. 6, the first through hole 103 penetrates from the inner surface 104 of the housing frame 1 to the outer surface 105 of the housing frame 1. The structure of the first through hole 103 is not particularly limited in the present application. For example, the first through hole 103 may be a circular hole, a square hole, an elliptical hole, a diamond hole, a pentagonal hole, a hexagonal hole, other irregular holes, and the like.

Referring to fig. 6, the key assembly 4 includes a first conductive member 41 and a second conductive member 42. The first and second

conductive members

41 and 42 may be a part or all of the detection electrode 300 disposed on the housing frame 1. The first conductive member 41 and the second conductive member 42 are made of conductive materials. The specific material can refer to the material of the detection electrode 300.

Referring to fig. 6, the first conductive member 41 is directly or indirectly connected to the housing frame 1. The direct connection means a connection manner of contacting. Indirect connection means that they are not in contact, but may be directly connected through other components. At least a portion of first conductive member 41 is located in external space 400. The first conductive member 41 may be partially disposed in the external space 400, such as a surface or a partial solid block, so that the person to be detected can directly contact the first conductive member 41. The first conductive member 41 may also be entirely provided in the external space 400. At least a portion of the second conductive member 42 is located within the first via 103. Optionally, a portion of the first conductive member 41 is disposed in the first through hole 103. Alternatively, the first conductive member 41 is entirely disposed in the first through hole 103.

Referring to fig. 6, the first conductive member 41 is elastically abutted against the second conductive member 42. The first conductive member 41 and the second conductive member 42 may be in direct contact with each other, or may be in indirect contact with each other, that is, in direct contact with each other through another structure. Wherein, the 'butt joint' includes that two buttresses are connected, and the acting force between the two buttresses in the connecting direction is greater than or equal to 0.

The first conductive member 41 and the second conductive member 42 can be electrically conducted. In other words, a conducting branch can be formed between the first conducting member 41 and the second conducting member 42.

Referring to fig. 6, the circuit assembly 5 is disposed in the cavity 102. The circuit assembly 5 includes a circuit board 51, an electrical contact 52 disposed on the circuit board 51, and a signal acquisition circuit (not shown). The circuit board 51 may be a flexible circuit board. The electrical contacts 52 are connected to the signal acquisition circuitry. Specifically, the electrical contact 52 and the signal acquisition circuit may be disposed on different circuit boards, for example, the electrical contact 52 is disposed on a flexible circuit board, the signal acquisition circuit is disposed on a motherboard, and the flexible circuit board is connected to the motherboard. In other alternative embodiments, the electrical contacts 52 and the signal acquisition circuitry may be provided on the same circuit board. For example, the electrical contacts 52 and the signal acquisition circuitry are all disposed on a flexible circuit board; alternatively, the electrical contacts 52 and the signal acquisition circuit are both disposed on the motherboard.

Referring to fig. 6, the electrical contact portion 52 abuts against an end of the second conductive member 42 away from the first conductive member 41, so that the first conductive member 41 is electrically connected to the electrical contact portion 52. When the person to be detected directly contacts the first conductive member 41, the person to be detected, the first conductive member 41, the second conductive member 42, the electrical contact portion 52 and the signal acquisition circuit are conducted, and the signal acquisition circuit can acquire the electrocardiogram information of the person to be detected. The first conductive member 41 is used to form a part or all of the detection electrode 300 for detecting biological information. Alternatively, the first conductive member 41, the second conductive member 42, and the electrical contact portion 52 may abut in sequence along the X-axis direction, the Y-axis direction, or the Z-axis direction. In the drawings of the present embodiment, the first conductive member 41, the second conductive member 42, and the electrical contact portion 52 are described as an example in which they are in contact with each other in the X-axis direction.

In this embodiment, referring to fig. 3, a third conductive member 500 is further disposed on the bottom case 3. The third conductive member 500 is at least partially disposed on the outer surface 105 of the bottom housing 3. The third conductive member 500 is connected to a signal collecting circuit. The third conductive member 500 and the first conductive member 41 are used to form a sensing electrode 300 for sensing biological information. The third conductive member 500 corresponds to one or both of the two detection electrodes 300 on the bottom chassis 3. The third conductive member 500 is disposed on the outer surface 105 of the bottom case 3. When the wearable electronic device 1000 is worn by the detected person, the signal acquisition circuit, the second conductive member 42, the first conductive member 41, the detected person and the third conductive member 500 form a conductive loop to detect the biological information of the detected person. The biological information corresponds to information collected by the signal collection circuit. In this embodiment, the biological information is electrocardiogram information.

Those skilled in the art can delete the third conductive member 500 according to actual needs. For example, in this embodiment, the third conductive member 500 is not provided, so that a complete technical solution can be formed to detect characteristic information such as temperature, pulse, blood oxygen, and the like.

Those skilled in the art can reasonably and easily change the position of the first conductive member 41, the position of the second conductive member 42, and the position of the third conductive member 500 according to actual needs, and all of them belong to the protection scope of the present application.

Compared with the integrated key assembly, the integrated key assembly directly transmits the impact force to the electrical contact part, so that under a large impact force, on one hand, the structure of the key assembly is likely to be broken due to impact, and on the other hand, the electrical contact part is likely to be broken under the large impact force, so that the structure of the electronic device is damaged, and the impact resistance of the electronic device is poor.

The electronic device 100 provided by the embodiment of the present application, by providing the split key assembly 4, the key assembly 4 can be used as a detection electrode 300, and by providing two parts of the key assembly 4 for elastic connection, when the first conductive piece 41 is collided, because the first conductive piece 41 and the second conductive piece 42 are elastically abutted, at least part of impact force can be absorbed by the elastic abutment, so as to reduce the distance that the second conductive piece 42 retreats due to the impact force, even the second conductive piece 42 cannot retreat, and further reduce the influence on the key assembly 4 itself or the key assembly 4 on the circuit assembly 5.

In this embodiment, referring to fig. 2, the top case 2 includes a display screen 21. The display screen 21 is used for displaying the biological information detected by the signal acquisition circuit, so that a person to be detected can visually see the detection result.

Optionally, the electrical contacts 52 are provided on the circuit board 51, the circuit board 51 facing the inner surface 104 of the housing frame 1. The circuit component 5 also includes a functional circuit (not shown) and a switch unit 53. The functional circuit is connected to the switching unit 53. The functional circuit may be provided on the circuit board 51 or on the motherboard. The switch unit 53 may be a key switch. When the switch unit 53 is not pressed, the functional circuit is in a short-circuited state. When the switch unit 53 receives a pressing force, the functional circuit is in a conductive state. The functional circuit is electrically connected with the control chip of the mainboard, and the functional circuit can be used for realizing one or more of functions of lightening the display screen 21, closing the display screen 21, increasing the volume, reducing the volume, taking a picture, starting a certain application program, closing a certain application program, opening the camera, closing the camera and the like after being conducted.

Referring to fig. 7, the circuit board 51 may be a flexible circuit board. The electronic device 100 further includes a circuit board support 54 for supporting the circuit board 51. The switch unit 53 is provided on the circuit board 51. Further, the electrical contact 52 is a conductive elastic sheet. The electrical contact part 52 is on the circuit board 51, the second conductive member 42 is in interference fit (contact) with the electrical contact part 52, and the first conductive member 41 and the second conductive member 42 are elastically connected. Finally, the first conductive member 41 and the electrical contact portion 52 are ensured to have good conductivity and low impedance, and normal use of electrocardiogram and other detection functions is ensured. The electrical contact 52, the first conductive member 41, and the second conductive member 42 may be optimized by a partial or full gold plating process to improve electrical conductivity and stability.

Referring to fig. 6 and 7, the electrical contact portion 52 includes a fixed end 521 and an abutting end 522 connected to the fixed end 521. The fixed end 521 is fixed to the circuit board 51. The fixed end 521 is connected with a signal acquisition circuit. The abutting end 522 is provided on a side of the switch unit 53 facing away from the flexible circuit board 51. The abutting end 522 is opposite to and spaced apart from the switch unit 53. The abutting end 522 abuts an end of the second conductive member 42 away from the first conductive member 41.

When the first conductive member 41 is pressed and the second conductive member 42 is pushed to move, the second conductive member 42 pushes the abutting end 522 to press the switch unit 53, so as to trigger the functional circuit to generate a trigger signal, thereby implementing the function of the functional circuit.

In other words, the key assembly 4 provided in the embodiment of the present application can be used as both the detection electrode 300 of the signal acquisition circuit and the trigger key of the functional circuit, so that one object of the key assembly 4 has multiple purposes, and the detection electrode 300 and the trigger key are multiplexed, so that the function integration is realized, the number of structures is reduced, and the cost and the space are saved.

Alternatively, first electrically-conductive member 41 may be a key cap of key assembly 4, and second electrically-conductive member 42 may be a key rod of key assembly 4. The key cap is a portion touched or pressed by a hand or other portion of the subject, and the key bar is a portion that transmits a current signal, a pressing force, and the like to the electrical contact portion 52.

Specifically, the first hook portion 412 and the second hook portion 413 are both hook-shaped, and the first hook portion 412 and the second hook portion 413 are arranged on two opposite sides of the main body 411 in a mirror symmetry manner. The first limiting member 61 and the second limiting member 62 may be bolts. The first limiting member 61 and the second limiting member 62 both extend along the Z-axis direction. The wall of the receiving groove 106 is provided with an insertion hole 63 adapted to the first position-limiting member 61 and an insertion hole 64 adapted to the second position-limiting member 62. The first conductive member 41 can be mounted in the accommodating groove 106 from the external space 400 side, and the two

insertion holes

63 and 64 correspond to the hook space of the first hook portion 412 and the hook space of the second hook portion 413, respectively, and at this time, the first stopper 61 and the second stopper 62 are inserted into the two

insertion holes

63 and 64 along the Z-axis direction from the side of the housing frame 1.

Optionally, since the first hook portion 412 and the second hook portion 413 are protruded relative to the main body 411, the bottom surface of the accommodating slot 106 may be provided with opposite grooves at positions corresponding to the first hook portion 412 and the second hook portion 413, and a gap may be formed between the bottom surface of the groove and the first hook portion 412 and the second hook portion 413, so that the distance between the bottom surface of the accommodating slot 106 and the outer surface 105 of the housing frame 1 may be shortened. In this manner, the thickness dimension of the housing frame 1 in the X-axis direction is reduced.

Optionally, referring to fig. 6 and fig. 7, the size of the first conductive member 41 in the Y-axis direction is far larger than the size of the first through hole 103 in the Y-axis direction. The electronic device 100 further includes a first elastic member 65 and a second elastic member 66 at least partially disposed in the receiving slot 106. The first elastic member 65 and the second elastic member 66 are respectively disposed at two opposite sides of the first through hole 103. The first elastic member 65 and the second elastic member 66 are elastically abutted against the bottom of the accommodating groove 106 and the first conductive member 41. The first elastic member 65 and the second elastic member 66 may both be in a compressed state. The first and second

elastic members

65 and 66 may provide enough elastic supporting force at opposite sides of the first through hole 103 so that any portion of the first conductive member 41 in the Y-axis direction is in a stable mounting state. Meanwhile, when the first conductive member 41 is pressed, the first and second

elastic members

65 and 66 may provide enough elastic restoring force to quickly react and restore to the original position when the pressing force of the first conductive member 41 is removed.

In this way, the first elastic member 65 and the second elastic member 66 have elastic force towards the external space 400 for the first conductive member 41, and the first limiting member 61 and the second limiting member 62 have restraining force towards the internal cavity 102 for the first conductive member 41, so that the first conductive member 41 is in a force balance state in the receiving slot 106. Meanwhile, the first hook portion 412 and the second hook portion 413 are spaced from the bottom surface of the receiving slot 106, the first limiting member 61 and the second limiting member 62 are spaced from the main body portion 411, and the first elastic member 65 and the second elastic member 66 can be further compressed, so that when the first conductive member 41 receives a pressing force toward the inner cavity 102 of the housing frame 1, the first conductive member 41 can further press the first elastic member 65 and the second elastic member 66, further press the second conductive member 42, and trigger the switch unit 53.

When the first conductive member 41 is pressed by the external pressure, the first elastic member 65, the elastic conductive member 7 and the second elastic member 66 are compressed, the first conductive member 41 moves toward the bottom of the receiving groove 106, and the first conductive member 41 pushes the second conductive member 42 to move toward the switching unit 53 to trigger the switching unit 53. When the external pressure of the first conductive member 41 is removed, the first conductive member 41 moves away from the bottom of the accommodating cavity 106 under the elastic deformation restoring force of the first elastic member 65, the elastic conductive member 7 and the second elastic member 66 until the first hooking portion 412 abuts against the first position-limiting member 61 and the second hooking portion 413 abuts against the second position-limiting member 62.

Further, the first elastic element 65 and the second elastic element 66 may be disposed close to the first hook portion 412 and the second hook portion 413, respectively, so as to increase the mounting stability of the first conductive element 41 and prevent the problems of unstable mounting, shaking, and the like.

The specific structures and specific materials of the first elastic member 65 and the second elastic member 66 are not specifically limited in this application, and optionally, the structures of the first elastic member 65 and the second elastic member 66 may be the same. For example, the first elastic member 65 and the second elastic member 66 are both springs. Alternatively, the first elastic element 65 and the second elastic element 66 may be elastic silicone, metal elastic sheet, plastic elastic sheet, or the like.

Further, referring to fig. 6 and 8, one end of the first elastic member 65 and one end of the second elastic member 66 may be fixed to the bottom surface of the receiving slot 106, so that the first elastic member 65 and the second elastic member 66 can be better fixed in the receiving slot 106. The side of the main body 411 facing the bottom surface of the receiving slot 106 may be provided with a groove 107 corresponding to the first elastic member 65 and a groove 108 corresponding to the second elastic member 66, so that a portion of the first elastic member 65 and a portion of the second elastic member 66 may be respectively received in the

grooves

107 and 108 in the main body 411, the first elastic member 65 and the second elastic member 66 may be positioned, and the thickness dimension of the housing frame 1 in the X-axis direction may be further reduced.

Optionally, the first conductive member 41 itself is made of an elastic conductive material, and the second conductive member 42 is made of a metal conductive material, when the first conductive member 41 receives an impact force, the first conductive member 41 is compressed under the impact force to absorb the impact force, so as to reduce the impact force transmitted to the circuit assembly 5 and destroy the structure on the force transmission path in the middle of transmission.

The second conductive member 42 may be in a cylindrical shape, and the specific shape may be in a cylindrical shape, a square cylindrical shape, or the like. The radial dimension of second conductive member 42 may be slightly smaller than the radial dimension of first via 103.

In an alternative embodiment, referring to fig. 6, the end of the second conductive member 42 facing the first conductive member 41 is provided with a first groove 110. A part of the conductive extensible member 71 is disposed in the first groove 110 and abuts against or is fixedly connected to the bottom of the first groove 110, on one hand, to position one end of the conductive extensible member 71, on the other hand, the inside of the second conductive member 42 provides a space for accommodating the conductive extensible member 71, and the existence of the accommodating space makes it unnecessary to reserve a space between the first conductive member 41 and the second conductive member 42, which needs to be occupied after the conductive extensible member 71 is compressed, in other words, the conductive extensible member 71 can be accommodated in the first groove 110 after being compressed, so that the distance between the first conductive member 41 and the second conductive member 42 can be used for absorbing pressure or impact force, and further, the overall assembly thickness of the first conductive member 41, the second conductive member 42, and the conductive extensible member 71 along the X-axis direction can be saved.

In an alternative embodiment, referring to fig. 6, a second groove 111 is formed on a side of the first conductive member 41 facing the second conductive member 42. The other end of the conductive expansion piece 71 abuts against or is fixedly connected with the bottom of the second groove 111.

Optionally, referring to fig. 6 and 7, the electronic device 100 further includes a sealing ring 67. The material of the sealing ring 67 includes, but is not limited to, rubber, silica gel, and the like having good sealing performance. The sealing ring 67 is disposed on the peripheral side surface of the second conductive member 42. The outer contour surface of the seal ring 67 is in contact with the hole wall of the first through hole 103 and is slidable relative thereto. The inner contour surface of the seal ring 67 is fitted to the peripheral side surface of the second conductive member 42. The sealing ring 67 itself is made of waterproof material, so that the sealing ring 67 is connected between the peripheral side surface of the second conductive member 42 and the hole wall of the first through hole 103 in a sealing manner, so as to achieve waterproofing between the second conductive member 42 and the housing frame 1, thereby preventing water from entering the circuit assembly 5 through the first through hole 103.

Further, an annular groove 68 is formed on the outer peripheral surface of the second conductive member 42, and the annular groove 68 is used for accommodating the sealing ring 67 to position the sealing ring 67. Further, the seal ring 67 is in a compressed state between the second conductive member 42 and the hole wall of the first through hole 103. The interference fit among the second conductive component 42, the sealing ring 67 and the hole wall of the first through hole 103 can realize the 5ATM waterproof requirement, namely, the waterproof performance of the component meets the atmospheric pressure waterproof degree of 5 ATM.

In a second embodiment, referring to fig. 10 and 11, the present embodiment is improved on the basis of the first embodiment, and the elastic conductive member 7 further includes an elastic pad 72.

Referring to fig. 10 and 11, the elastic pad 72 is disposed between the first conductive member 41 and the second conductive member 42, and the compressibility of the elastic pad 72 enables the first conductive member 41 and the second conductive member 42 to absorb a tolerance band under the condition of a manufacturing error, so as to ensure the stability of hand feeling of the key assembly 4 in the mass production process; the elastic gasket 72 can also ensure that the elastic gasket 72 is not easily deformed relative to the spring and the like under the limit working condition, so that more impact force can be absorbed, the key assembly 4 can buffer in the collision/falling process, the key assembly 4 cannot fail under the collision/falling condition, and the service life of the key assembly can be ensured.

Further, the elastic pad 72 is in a compressed state. In short, the elastic pad 72 is interference-fitted between the first conductive member 41 and the second conductive member 42, that is, the elastic pad 72 is pressed between the first conductive member 41 and the second conductive member 42 along the X-axis direction, the elastic pad 72 has a pressing counter force against the first conductive member 41 in the positive direction toward the X-axis direction, and the elastic pad 72 has a pressing counter force against the second conductive member 42 in the negative direction toward the X-axis direction. Thus, the elastic pad 72 can support the first conductive member 41, prevent the key assembly 4 from shaking, and improve the stability of the key assembly 4.

Specifically, referring to fig. 12, the elastic pad 72 and the conductive expansion member 71 are sleeved with each other in the X-axis direction. Optionally, the elastic pad 72 is sleeved on the outer circumference of the conductive telescopic member 71. Optionally, the conductive expansion piece 71 is sleeved on the outer circumference of the elastic pad 72. The overlapping size of the elastic gasket 72 and the conductive expansion piece 71 in the X-axis direction is reduced by the above design, so that the structures of the elastic conductive piece 7, the first conductive piece 41 and the second conductive piece 42 are more compact.

Referring to fig. 10, the side of the elastic pad 72 facing the second conductive member 42 and the bottom surface of the receiving groove 106 may be spaced apart. The elastic pad 72 may cover the first through hole 103 by an orthographic projection of the second conductive member 42 side to provide a large enough impact absorbing area and a larger supporting area for the first conductive member 41. One end of the second conductive member 42 extending into the receiving slot 106 abuts against the elastic pad 72, so that the elastic pad 72 is compressed between the first conductive member 41 and the second conductive member 42.

Referring to fig. 12, the elastic pad 72 has a second through hole 109 in communication with the first through hole 103. Referring to fig. 10, the second via 109 can be electrically connected to the first recess 110 and the second recess 111. One end of the conductive telescopic member 71 abuts against or is fixedly connected with the bottom plate of the first groove 110, the conductive telescopic member 71 penetrates through the second through hole 109, and the other end of the conductive telescopic member 71 abuts against or is fixedly connected with the bottom of the second groove 111. In this way, the conductive expansion piece 71 is disposed through the second through hole 109 to reduce the overall overlapping size of the conductive expansion piece 71 and the elastic pad 72 in the X-axis direction.

The expansion and contraction of the conductive expansion piece 71 in the X-axis direction and the expansion and contraction of the elastic pad 72 in the X-axis direction may be independent of each other and arranged in parallel. Thus, the conductive expansion element 71 and the elastic pad 72 can provide elastic supporting force for the first conductive element 41, so that the key assembly 4 can be stably mounted.

Different from the second embodiment, a part of the conductive extensible member 71 is sleeved on the peripheral side surface of the second conductive member 42, and the peripheral side surface is opposite to the hole wall of the first through hole 103, so that the contact area between the conductive extensible member 71 and the second conductive member 42 can be increased, and the electrical connection reliability between the conductive extensible member 71 and the second conductive member 42 can be improved. When the conductive expansion piece 71 is sleeved on the peripheral side surface of the second conductive member 42, one end of the conductive expansion piece 71 can be fixedly connected or slidably connected with the peripheral side surface of the second conductive member 42.

Further, referring to fig. 13, a clamping column 421 is disposed on the peripheral side surface of the second conductive member 42. The capture posts 421 extend in a radial direction.

In other words, one end of the conductive extensible member 71 in the present embodiment may be the other end of the conductive extensible member 71 in the first embodiment, or may be one end of the conductive extensible member 71 in the first embodiment.

Furthermore, the positioning posts 421 in this embodiment may be formed by forming annular grooves 68 and thinned posts on the peripheral side surface of the columnar second conductive member 42 at intervals along the X-axis direction, and forming the positioning posts 421 between the annular grooves 68 and the thinned posts.

Alternatively, the conductive expansion member 71 may be disposed in the second through hole 109, that is, the second conductive member 42, the conductive expansion member 71 and the elastic pad 72 are sequentially disposed from inside to outside in the Y-axis direction. Still alternatively, the conductive elastic member 71 may be connected with the elastic pad 72 such that the elastic pad 72 and the impact absorbing capability of the conductive elastic member 71 are superimposed in the X-axis direction. Specifically, the conductive expansion member 71 is a spring, and the conductive expansion member 71 can be arranged in the elastic gasket 72 in a penetrating manner; or, the elastic gasket 72 is clamped between two adjacent spiral coils of the conductive extensible member 71, so that the elastic gasket 72 and the conductive extensible member 71 are fixed, the connection stability between the elastic gasket 72 and the conductive extensible member 71 is improved, and the conductive extensible member 71 and the elastic gasket 72 are stacked in the X-axis direction, so that the impact absorption capacities of the elastic gasket 72 and the conductive extensible member 71 are stacked in the X-axis direction.

The end surface of the protruding portion 422 is opposed to and spaced from the bottom wall of the groove portion 414. The peripheral side surface of the protruding portion 422 is slidably connected to the peripheral side wall of the groove portion 414, so that the first conductive member 41 and the second conductive member 42 are slidably connected in the X-axis direction, the first conductive member 41 and the second conductive member 42 can be kept in contact, and further the first conductive member 41 and the second conductive member 42 are conducted, thereby increasing the electrical connection stability between the first conductive member 41 and the second conductive member 42, and the elastic structure does not need to be a conductive structure.
