[0002] As people's demands for the functionality of electronic devices increase, the requirements for the button components of these devices are also becoming more stringent. Button components can serve as electrodes for detecting biometric features. However, since these components are located on the outer surface of electronic devices, they are susceptible to impacts from collisions or drops, which can affect the circuitry connected to them. Therefore, this application proposes an electronic device with a button component that has good impact resistance, which is a technical problem that needs to be solved. Summary of the Invention

[0003] This application provides an electronic device and a wearable electronic device with a button assembly that has good impact resistance.

[0007] A circuit assembly is disposed in the inner cavity. The circuit assembly includes an electrical contact portion, which abuts against the end of the second conductive member away from the first conductive member, so that the first conductive member is electrically connected to the electrical contact portion.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The embodiments listed in this application can be appropriately combined with each other.

[0030] Please see Figure 1 The electronic device 100 provided in this application can be applied to wearable electronic devices 1000, including but not limited to smartwatches, smart bracelets, smart glasses, smart helmets, smart headphones, smart necklaces, smart rings, and other electronic devices. Optionally, the wearable electronic device 1000 includes a sensor, and its casing may have detection electrodes connected to the sensor. The wearable device can be worn on a wearable subject (human body, animal, or object, etc.), and its characteristic information is detected through contact between the detection electrodes and the wearable subject. This application uses a smartwatch as an example to illustrate the concept.

[0031] Among them, the sensors used to detect feature information include, but are not limited to, heart rate sensors, biosensors, and skin conductance sensors.

[0034] Skin conductance sensors are sensors that detect skin resistance or conductance and can be used to detect lie or to detect periods of high work or study efficiency.

[0035] Of course, the wearable electronic device 1000 can also incorporate motion sensors, environmental sensors, etc., to integrate more functions. Motion sensors include, but are not limited to, accelerometers, gyroscopes, geomagnetic sensors (electronic compass sensors), and atmospheric pressure sensors. Environmental sensors include, but are not limited to, air temperature and humidity sensors, rain sensors, light sensors, and wind speed and direction sensors.

[0036] Please see Figure 1 This application provides a wearable electronic device 1000. The wearable electronic device 1000 includes an electronic device 100 and a wearable component 200. The wearable component 200 is connected to the electronic device 100. The electronic device 100 is the functional main body of the wearable electronic device 1000. The wearable component 200 can be a bracelet, necklace, ring, eyeglass frame, or other connection structure used to wear the electronic device 100 onto the wearable main body.

[0037] The electronic device 100 may be fixedly connected to the wearable device 200, or the electronic device 100 may be detachably connected to the wearable device 200.

[0038] This embodiment uses the example of an electronic device 100 capable of detecting electrocardiograms to specifically illustrate the structure of the electronic device 100. Of course, the electronic device 100 can also be designed with reference to this embodiment when used to detect other feature information, and this also falls within the scope of protection of this application.

[0039] Electronic device 100 includes an electrocardiogram (ECG) detector. The ECG detector includes one or more detection electrodes and signal acquisition circuitry connected to the detection electrodes.

[0040] The detection electrode is made of a conductive material, including but not limited to metals, metal oxides, graphene, conductive graphite, conductive carbon black, single-walled and multi-walled carbon nanotubes. The metal in the detection electrode can be in the form of metal nanowires, metal nanoparticles, or metal oxide nanoparticles. The metal composition includes, but is not limited to, gold, silver, copper, aluminum, or nickel. The metal oxide composition includes, but is not limited to, indium tin oxide (ITO) or fluorine-doped tin oxide (FTO).

[0041] For the electronic device 100 for detecting electrocardiograms in this embodiment, the number of detection electrodes in the electronic device 100 is at least three.

[0042] These detection electrodes can be disposed on the outer surface of the casing of the electronic device 100. When the wearable electronic device 1000 is worn by the subject (i.e., the wearer mentioned above), these detection electrodes contact the subject's detection area to detect the subject's electrocardiogram. Taking a smartwatch as an example, the electronic device 100 is the watch face, and the wearable component 200 is the watch strap. The watch face can be round, square, curved, irregularly shaped, etc. This embodiment uses a square watch face as an example.

[0043] For ease of description, the length direction of the electronic device 100 is defined as the Y-axis direction, the width direction of the electronic device 100 is defined as the X-axis direction, and the thickness direction of the electronic device 100 is defined as the Z-axis direction.

[0044] Please see Figure 2 The electronic device 100 includes a housing frame 1. Optionally, the housing frame 1 can be a side frame of the electronic device 100. For details, please refer to the relevant documentation. Figure 3 and Figure 4 The electronic device 100 also includes a top shell 2 and a bottom shell 3 disposed opposite to each other, with a housing frame 1 connected between the top shell 2 and the bottom shell 3. The top shell 2, housing frame 1, and bottom shell 3 surround and form a sealed or nearly sealed receiving cavity 101. The receiving cavity 101 can accommodate circuit boards, sensors, batteries, and other devices. In other words, the top shell 2, housing frame 1, and bottom shell 3 form the overall outer casing of the electronic device 100.

[0045] Please see Figure 3When the subject wears the wearable electronic device 1000, the subject's wrist contacts the bottom shell 3 of the electronic device 100. In this embodiment, the number of detection electrodes 300 can be three. Of course, three is just an example and does not limit the number of detection electrodes 300. Optionally, two detection electrodes 300 are disposed on the outer surface of the bottom shell 3, and the other detection electrode 300 is disposed on the outer surface of the housing frame 1. This embodiment will be described in the following description. In other optional embodiments, two detection electrodes 300 are disposed on the bottom shell 3, and the other detection electrode 300 is disposed on the top shell 2. The two detection electrodes 300 disposed on the bottom shell 3 are independent of each other, that is, 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 shell 3 are always in contact with the subject's skin. 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 to the signal acquisition circuit in the receiving cavity 101. Another detection electrode 300 is also connected to the signal acquisition circuit of the receiving cavity 101.

[0046] When the wearable electronic device 1000 is worn on the left hand of the subject, both detection electrodes 300 are in contact with the subject's left hand. The left hand is merely an example and does not limit the wearing location of the wearable electronic device 1000. The conduction circuit at this time is: left hand - detection electrode 300 on the bottom shell 3 - signal acquisition circuit. When the subject's right hand touches or presses the detection electrode 300 on the housing frame 1, the conduction circuit is: right hand - detection electrode 300 on the housing frame 1 - signal acquisition circuit. The signal acquisition circuit acquires the voltage difference between the left and right hands and then generates an electrocardiogram waveform based on the voltage difference. Of the two detection electrodes 300 on the housing, one detection electrode 300 can be a driving electrode to enhance the anti-interference capability of the signal acquisition circuit.

[0047] Optionally, the housing frame 1 described in this application can also be the overall outer shell of the electronic device 100. In other words, the button assembly 4 of the electronic device 100 described in this application can be located in the top shell 2, the bottom shell 3, or the side shell.

[0048] Optionally, the housing frame 1 can also be an integrally formed combined housing of the bottom shell 3 and the side shell of the electronic device 100. In other words, the button assembly 4 of the electronic device 100 described in this application can be located in the bottom shell 3 or the side shell.

[0049] The specific structure of the electronic device 100 is illustrated below with reference to the accompanying drawings.

[0050] Please see Figure 4 and Figure 5 The electronic device 100 includes a housing frame 1, a button assembly 4, and a circuit assembly 5.

[0051] In this embodiment, please refer to Figure 5 and Figure 6 The housing frame 1 is a side shell. The housing frame 1 has an inner cavity 102 and a first through hole 103. The first through hole 103 connects the inner cavity 102 with the 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 disposed opposite to each other. The space enclosed by the inner surface 104 is the inner cavity 102 of the housing frame 1. When the electronic device 100 has a top shell 2 and a bottom shell 3, the surface of the top shell 2 facing the bottom shell 3, the annular inner surface 104 of the housing frame 1, and the surface of the bottom shell 3 facing the top shell 2 enclose the inner cavity 102. The external space 400 is the space of the annular outer surface 105 of the housing frame 1 facing away from the annular inner surface 104. Optionally, the inner surface 104 of the housing frame 1 may include a plane, a curved surface, an uneven surface, etc. The outer surface 105 of the shell frame 1 may include a flat surface, a curved surface, an uneven surface, etc. The shell frame 1 can be an independent structure formed of a single material, or a composite structure or spliced ​​structure formed of multiple different materials through processes such as pressing and injection molding.

[0052] Please see Figure 6 The first through hole 103 extends from the inner surface 104 of the housing frame 1 to the outer surface 105 of the housing frame 1. This application does not specifically limit the structure of the first through hole 103. For example, the first through hole 103 can be a circular hole, a square hole, an elliptical hole, a rhomboid hole, a pentagonal hole, a hexagonal hole, or other irregularly shaped holes, etc.

[0053] Please see Figure 6 The button assembly 4 includes a first conductive element 41 and a second conductive element 42. The first conductive element 41 and the second conductive element 42 can be understood as part or all of the detection electrode 300 disposed on the housing frame 1. Both the first conductive element 41 and the second conductive element 42 are made of conductive material. For specific material details, please refer to the material of the detection electrode 300 described above.

[0054] Please see Figure 6 The first conductive element 41 is directly or indirectly connected to the housing frame 1. Direct connection refers to a connection where parts are in contact. Indirect connection refers to a connection that is not in contact but can be directly connected through other components. At least a portion of the first conductive element 41 is located in the external space 400. The first conductive element 41 may be partially located in the external space 400, such as a surface or a partial three-dimensional block, so that the person being tested can directly contact the first conductive element 41. The first conductive element 41 may also be entirely located in the external space 400. At least a portion of the second conductive element 42 is located within the first through hole 103. Optionally, a portion of the first conductive element 41 is located in the first through hole 103. Alternatively, the entire first conductive element 41 may be located in the first through hole 103.

[0055] Please see Figure 6The first conductive element 41 and the second conductive element 42 are elastically abutted together. The first conductive element 41 and the second conductive element 42 can be directly abutted or indirectly abutted together, that is, directly abutted together through other structures. Herein, "abutting" includes the two abutting elements being connected, and there is a force greater than or equal to 0 between the two abutting elements in the connection direction.

[0056] The first conductive element 41 and the second conductive element 42 are electrically connected. In other words, a conductive branch can be formed between the first conductive element 41 and the second conductive element 42.

[0057] Please see Figure 6 The circuit assembly 5 is disposed within the inner cavity 102. The circuit assembly 5 includes a circuit board 51 and electrical contacts 52 and a signal acquisition circuit (not shown) disposed on the circuit board 51. The circuit board 51 can be a flexible circuit board. The electrical contacts 52 are connected to the signal acquisition circuit. Specifically, the electrical contacts 52 and the signal acquisition circuit can be disposed on different circuit boards. For example, the electrical contacts 52 are disposed on a flexible circuit board, and the signal acquisition circuit is disposed on a main board, with the flexible circuit board connected to the main board. In other optional embodiments, the electrical contacts 52 and the signal acquisition circuit can be disposed on the same circuit board. For example, both the electrical contacts 52 and the signal acquisition circuit are disposed on a flexible circuit board; or, both the electrical contacts 52 and the signal acquisition circuit are disposed on the main board.

[0058] Please see Figure 6 The electrical contact 52 abuts against the end of the second conductive element 42 furthest from the first conductive element 41, making the first conductive element 41 and the electrical contact 52 electrically connected. When the subject directly contacts the first conductive element 41, the subject, the first conductive element 41, the second conductive element 42, the electrical contact 52, and the signal acquisition circuit are connected, and the signal acquisition circuit can acquire the electrocardiogram information of the subject. The first conductive element 41 is used to form part or all of the detection electrode 300 for detecting biological information. Optionally, the first conductive element 41, the second conductive element 42, and the electrical contact 52 can abut sequentially along the X-axis, Y-axis, or Z-axis. In this embodiment, the illustration shows the first conductive element 41, the second conductive element 42, and the electrical contact 52 abutting sequentially along the X-axis.

[0059] In this embodiment, please refer to Figure 3A third conductive element 500 is also provided on the bottom shell 3. The third conductive element 500 is at least partially disposed on the outer surface 105 of the bottom shell 3. The third conductive element 500 is connected to the signal acquisition circuit. The third conductive element 500 and the first conductive element 41 are used to form a detection electrode 300 for detecting biological information. The third conductive element 500 corresponds to one or both of the two detection electrodes 300 on the bottom shell 3. The third conductive element 500 is disposed on the outer surface 105 of the bottom shell 3. When the subject wears the wearable electronic device 1000, the signal acquisition circuit, the second conductive element 42, the first conductive element 41, the subject, and the third conductive element 500 form a conductive circuit to detect the subject's biological information. The biological information corresponds to the information acquired by the signal acquisition circuit. In this embodiment, the biological information is electrocardiogram information.

[0060] Those skilled in the art can omit the third conductive element 500 according to actual needs. For example, a complete technical solution can be formed without the third conductive element 500 in this embodiment to detect characteristic information such as temperature, pulse, and blood oxygen.

[0061] Those skilled in the art can make reasonable and easily conceivable changes to the positions of the first conductive element 41, the second conductive element 42, and the third conductive element 500 according to actual needs, all of which fall within the protection scope of this application.

[0062] Compared to integrated button assemblies, integrated button assemblies directly transmit the impact force to the electrical contact part. Thus, under a large impact, the button assembly itself may break due to the impact, and the electrical contact part may also break under a large impact, resulting in damage to the structure of the electronic device and poor impact resistance.

[0063] The electronic device 100 provided in this application embodiment provides a split button assembly 4, which can serve as a detection electrode 300. By setting the two parts of the button assembly 4 to be elastically connected, when the first conductive element 41 is impacted, the elastic contact between the first conductive element 41 and the second conductive element 42 can absorb at least part of the impact force, thereby reducing the distance that the second conductive element 42 will retreat due to the impact force, or even preventing the second conductive element 42 from retreating, thereby reducing the impact on the button assembly 4 itself or the button assembly 4 on the circuit assembly 5.

[0064] In this embodiment, please refer to Figure 2 The top shell 2 includes a display screen 21. The display screen 21 is used to display the biological information detected by the signal acquisition circuit so that the person being tested can intuitively see the test results.

[0065] Optionally, the electrical contact 52 is disposed on the circuit board 51, with the circuit board 51 facing the inner surface 104 of the housing frame 1. The circuit assembly 5 also includes a functional circuit (not shown) and a switch unit 53. The functional circuit is connected to the switch unit 53. The functional circuit can be disposed on the circuit board 51 or on the motherboard. The switch unit 53 can be a push-button switch. When the switch unit 53 is not pressed, the functional circuit is in a short-circuit state. When the switch unit 53 is pressed, the functional circuit is in a conducting state. The functional circuit is electrically connected to the control chip of the motherboard. After being turned on, the functional circuit can be used to realize one or more of the following functions: turning on the display screen 21, turning off the display screen 21, increasing the volume, decreasing the volume, taking a picture, opening an application, closing an application, opening the camera, and closing the camera.

[0066] Please see Figure 7 The circuit board 51 can be a flexible circuit board. The electronic device 100 also includes a circuit board support 54 for supporting the circuit board 51. The switching unit 53 is disposed on the circuit board 51. Further, the electrical contact 52 is a conductive spring. The electrical contact 52 is on the circuit board 51, and the second conductive element 42 is interference-fitted (abutting) with the electrical contact 52, while the first conductive element 41 and the second conductive element 42 are elastically connected. Ultimately, this ensures good conductivity between the first conductive element 41 and the electrical contact 52, and low impedance, ensuring normal operation of detection functions such as electrocardiogram. The electrical contact 52, the first conductive element 41, and the second conductive element 42 can be optimized using partial or complete gold plating processes to improve conductivity and stability.

[0067] Please see Figure 6 and Figure 7 The electrical contact portion 52 includes a fixed end 521 and an abutment 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 to the signal acquisition circuit. The abutment end 522 is located on the side of the switching unit 53 away from the flexible circuit board 51. The abutment end 522 is opposite to the switching unit 53 and spaced apart. The abutment end 522 abuts against the end of the second conductive member 42 away from the first conductive member 41.

[0068] When the first conductive element 41 is pressed and pushes the second conductive element 42 to move, the second conductive element 42 pushes the abutment end 522 to press the switch unit 53, thereby triggering the functional circuit to generate a trigger signal and realize the function of the functional circuit.

[0069] In other words, the button assembly 4 provided in this application embodiment can serve as both a detection electrode 300 of the signal acquisition circuit and a trigger button of the functional circuit, realizing the multi-purpose use of the button assembly 4. By reusing the detection electrode 300 and the trigger button, functional integration is achieved, reducing the number of structures and saving costs and space.

[0070] Optionally, the first conductive element 41 can be the keycap of the button assembly 4, and the second conductive element 42 can be the key lever of the button assembly 4. The keycap is the part touched or pressed by the hand or other parts of the person being tested, and the key lever is the part that conducts current signals, pressing pressure, etc. to the electrical contact part 52.

A first through hole 103 connects the receiving groove 106 and the inner cavity 102 of the housing frame 1. In other words, the receiving groove 106 forms an opening on the outer surface 105 of the housing frame 1. The bottom surface of the receiving groove 106 is opposite to the opening of the receiving groove 106. The first through hole 103 penetrates the bottom surface of the receiving groove 106.

Optionally, a portion of the first conductive element 41 may be located within the receiving groove 106. Another portion of the first conductive element 41 may be located outside the outer surface 105 of the housing frame 1. In other words, the outer surface 105 of the first conductive element 41 may slightly protrude from the outer surface 105 of the housing frame 1 to form a pressing protrusion. Alternatively, yet another portion of the first conductive element 41 may be located within the first through hole 103.

Taking an insulating film as an example, the insulating film is used to insulate the button assembly 4 from the metal surfaces of the housing frame 1. Optionally, the insulating film can also be provided on multiple metal surfaces of the housing frame 1 opposite to the button assembly 4.

[0075] Optionally, the housing frame 1 may be made entirely or partially of a non-conductive material. The portion of the housing frame 1 that houses the button assembly 4 may also be made of a non-conductive material, so that there is no electrical conductivity between the housing frame 1 and the button assembly 4.

In other optional embodiments, the size of the receiving groove 106 in at least one of the X-axis or Y-axis directions may be equal to the size of the first through hole 103; or the size of the receiving groove 106 in at least one of the X-axis or Y-axis directions may be smaller than the size of the first through hole 103.

[0077] Of course, in other embodiments, the outer peripheral wall of the housing frame 1 may not be provided with a receiving groove 106, a part of the first conductive element 41 is provided in the first through hole 103, and another part of the first conductive element 41 protrudes from the outer surface 105 of the housing frame 1.

[0078] The installation method of the first conductive element 41 in the receiving groove 106 includes, but is not limited to, the following embodiments.

[0079] Optional, please refer to Figure 7 and Figure 8 The electronic device 100 also includes a first limiting member 61 and a second limiting member 62 disposed in the receiving groove 106. The first limiting member 61 and the second limiting member 62 are respectively used to limit the opposite ends of the first conductive member 41. Optionally, the first conductive member 41 includes a main body portion 411, a first hook portion 412, and a second hook portion 413. The main body portion 411 covers part or all of the opening of the receiving groove 106.

The second limiting member 62 abuts against the side of the second hook portion 413 opposite to the bottom of the receiving groove 106 and is spaced apart from the main body portion 411.

[0080] Optional, please refer to Figure 6 and Figure 8The structures of the first hook portion 412 and the second hook portion 413 can be identical, and the structures of the first limiting member 61 and the second limiting member 62 can also be identical. Specifically, both the first hook portion 412 and the second hook portion 413 are hook-shaped, and are mirror-symmetrically arranged on opposite sides of the main body portion 411. The first limiting member 61 and the second limiting member 62 can be pins. Both the first limiting member 61 and the second limiting member 62 extend along the Z-axis direction. The groove wall of the receiving groove 106 is provided with an insertion hole 63 that matches the first limiting member 61 and an insertion hole 64 that matches the second limiting member 62. The first conductive member 41 can be installed in the receiving 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 part 412 and the hook space of the second hook part 413 respectively. At this time, the first limiting member 61 and the second limiting member 62 are inserted into the two insertion holes 63 and 64 respectively from the side of the housing frame 1 along the Z-axis direction.

[0081] Optionally, since the first hook portion 412 and the second hook portion 413 protrude relative to the main body portion 411, the bottom surface of the receiving groove 106 can be provided with corresponding grooves at positions corresponding to the first hook portion 412 and the second hook portion 413. A gap can 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 receiving groove 106 and the outer surface 105 of the housing frame 1 can be shortened. In this way, the thickness dimension of the housing frame 1 in the X-axis direction is reduced.

[0082] Optional, please refer to Figure 6 and Figure 7 The dimension of the first conductive element 41 in the Y-axis direction is much larger than the dimension of the first through hole 103 in the Y-axis direction. The electronic device 100 also includes a first elastic element 65 and a second elastic element 66, at least partially disposed within the receiving groove 106. The first elastic element 65 and the second elastic element 66 are respectively disposed on opposite sides of the first through hole 103. Both the first elastic element 65 and the second elastic element 66 elastically abut against the bottom of the receiving groove 106 and the first conductive element 41. Both the first elastic element 65 and the second elastic element 66 can be in a compressed state. The first elastic element 65 and the second elastic element 66 can provide sufficient elastic support force on opposite sides of the first through hole 103 to ensure that the first conductive element 41 is stably installed in any part of the Y-axis direction. Simultaneously, when the first conductive element 41 is pressed, the first elastic element 65 and the second elastic element 66 can provide sufficient elastic restoring force to allow the first conductive element 41 to react quickly and return to its original position when the pressing force is removed.

[0083] Thus, the first elastic member 65 and the second elastic member 66 exert elastic forces on the first conductive member 41 toward the external space 400, and the first limiting member 61 and the second limiting member 62 exert constraining forces on the first conductive member 41 toward the inner cavity 102, thereby ensuring that the first conductive member 41 is in a state of force balance within the receiving groove 106. Simultaneously, the first hook portion 412 and the second hook portion 413 are spaced apart from the bottom surface of the receiving groove 106, and the first limiting member 61, the second limiting member 62, and the main body portion 411 are spaced apart. The first elastic member 65 and the second elastic member 66 can be further compressed. Thus, when the first conductive member 41 is subjected to pressure 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, and further press the second conductive member 42, triggering the switch unit 53.

[0084] When the first conductive element 41 is pressed by external pressure, the first elastic element 65, the elastic conductive element 7, and the second elastic element 66 are compressed. The first conductive element 41 moves toward the bottom of the receiving groove 106, and pushes the second conductive element 42 toward the switching unit 53 to trigger the switching unit 53. When the external pressure on the first conductive element 41 is removed, the first conductive element 41 moves away from the bottom of the receiving groove 106 under the elastic deformation restoring force of the first elastic element 65, the elastic conductive element 7, and the second elastic element 66 until the first hook portion 412 abuts against the first limiting member 61, and the second hook portion 413 abuts against the second limiting member 62.

[0085] Furthermore, the first elastic member 65 and the second elastic member 66 can be respectively positioned close to the first hook portion 412 and the second hook portion 413 to increase the installation stability of the first conductive member 41 and prevent problems such as unstable installation and shaking.

[0086] This application does not impose specific limitations on the specific structure or material of the first elastic element 65 and the second elastic element 66. Optionally, the structures of the first elastic element 65 and the second elastic element 66 can be the same. For example, both the first elastic element 65 and the second elastic element 66 can be springs. Other optional materials for the first elastic element 65 and the second elastic element 66 include elastic silicone, metal springs, and plastic springs.

[0087] Further, please refer to Figure 6 and Figure 8One end of the first elastic member 65 and one end of the second elastic member 66 can be fixed to the bottom surface of the receiving groove 106, so that the first elastic member 65 and the second elastic member 66 can be better fixed in the receiving groove 106. The side of the main body 411 facing the bottom surface of the receiving groove 106 can 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 can be respectively received in the grooves 107 and 108 in the main body 411, which can position the first elastic member 65 and the second elastic member 66, and can further reduce the thickness of the housing frame 1 in the X-axis direction.

[0088] The elastic contact between the first conductive element 41 and the second conductive element 42 includes, but is not limited to, the following two situations: one is that at least one of the first conductive element 41 and the second conductive element 42 is made of an elastic conductive material, and the first conductive element 41 and the second conductive element 42 are in direct contact; the other is that an elastic conductive element 7 is provided between the first conductive element 41 and the second conductive element 42, and the elastic conductive element 7 elastically abuts against the first conductive element 41 and the second conductive element 42.

[0089] The following description, in conjunction with the accompanying drawings, illustrates specific embodiments of the elastic contact between the first conductive element 41 and the second conductive element 42. Of course, the elastic contact between the first conductive element 41 and the second conductive element 42 in the embodiments of this application includes, but is not limited to, the following embodiments.

[0090] For the first possible implementation, please refer to Figures 6 to 8 The first conductive element 41 and the second conductive element 42 are connected by an elastic conductive element 7 (which can be elastic contact) so that the first conductive element 41 and the second conductive element 42 can move relative to each other.

[0091] Specifically, the elastic conductive component 7 includes, but is not limited to, springs, metal springs, plastic springs, elastic conductive silicone, elastic conductive rubber, elastic conductive foam, etc.

[0092] For the first conductive element 41 and the second conductive element 42 to move relative to each other, the first conductive element 41 and the second conductive element 42 can be spaced apart. An elastic conductive element 7 elastically abuts against the first conductive element 41 and the second conductive element 42. Under external force, the first conductive element 41 presses against the elastic conductive element 7, compressing the elastic conductive element 7. During the compression of the elastic conductive element 7, the first conductive element 41 gradually moves closer to the second conductive element 42. The elastic conductive element 7 can simultaneously achieve electrical connection and elastic buffering between the first conductive element 41 and the second conductive element 42.

[0093] For the first conductive element 41 and the second conductive element 42 to move relative to each other, the first conductive element 41 and the second conductive element 42 are slidably connected. When the first conductive element 41 is pressed against the elastic conductive element 7 by an external force, the first conductive element 41 slides relative to the second conductive element 42 and gradually moves closer to the second conductive element 42. The elastic conductive element 7 can simultaneously achieve electrical connection and elastic buffering between the first conductive element 41 and the second conductive element 42.

[0094] For a second possible implementation, please refer to Figure 9 The first conductive element 41 and the second conductive element 42 abut against each other. At least one of the first conductive element 41 and the second conductive element 42 is made of an elastic conductive material. For example, at least one of the first conductive element 41 and the second conductive element 42 is elastic conductive rubber, elastic conductive silicone, etc. Optionally, the first conductive element 41 itself is an elastic conductive material, and the second conductive element 42 is a metallic conductive material. When the first conductive element 41 is subjected to an impact force, the first conductive element 41 will compress under the impact force to absorb the impact force and reduce the impact force transmitted to the circuit component 5 and the structure in the force transmission path in the middle of the transmission. Optionally, the second conductive element 42 is an elastic conductive material, and the first conductive element 41 is a metallic conductive material. Other optional embodiments include the second conductive element 42 being an elastic conductive material and the first conductive element 41 being an elastic conductive material. All of the above embodiments can be used to reduce impact force.

[0095] The specific implementation of the connection between the first conductive element 41 and the second conductive element 42 via the elastic conductive element 7 includes, but is not limited to, the following implementation.

[0096] In the first implementation, please refer to Figure 7 The elastic conductive component 7 includes a conductive telescopic component 71. One end of the conductive telescopic component 71 is connected to the first conductive component 41, and this connection can be achieved through direct contact, bonding with conductive adhesive, welding, pressing together, or connection via a conductive snap-fit ​​component. The other end of the conductive telescopic component 71 is connected to the second conductive component 42, and this connection can also be achieved through direct contact, bonding with conductive adhesive, welding, pressing together, or connection via a conductive snap-fit ​​component. The conductive telescopic component 71 includes, but is not limited to, conductive springs, conductive contact sheets, and conductive silicone.

[0097] Specifically, one end of the second conductive element 42 can be located within the receiving groove 106 and abut against the first conductive element 41 via the conductive telescopic member 71. The first conductive element 41 and the second conductive element 42 can be spaced apart. The conductive telescopic member 71 is disposed between the first conductive element 41 and the second conductive element 42. The second conductive element 42 passes through the first through hole 103, and the other end of the second conductive element 42 extends into the inner cavity 102 and abuts against the electrical contact portion 52. When the first conductive element 41 pushes the conductive telescopic member 71 to compress, the conductive telescopic member 71 pushes the second conductive element 42 to move within the second through hole and press against the electrical contact portion 52, thereby performing the aforementioned biometric detection or triggering the switching unit 53 to conduct.

[0098] The second conductive element 42 may be columnar, and its specific shape may be cylindrical, square, or otherwise unrestricted. The radial dimension of the second conductive element 42 may be slightly smaller than the radial dimension of the first through hole 103.

[0099] In one alternative implementation, please refer to Figure 6 The second conductive element 42 has a first groove 110 at one end facing the first conductive element 41. A portion of the conductive telescopic element 71 is disposed in the first groove 110 and abuts against or is fixedly connected to the bottom of the first groove 110. On the one hand, this positions one end of the conductive telescopic element 71. On the other hand, the interior of the second conductive element 42 provides space to accommodate the conductive telescopic element 71. The existence of this space means that there is no need to reserve space between the first conductive element 41 and the second conductive element 42 for the space occupied by the conductive telescopic element 71 after compression. In other words, the conductive telescopic element 71 can be accommodated in the first groove 110 after compression, so that the distance between the first conductive element 41 and the second conductive element 42 can be used entirely to absorb pressure or impact, thereby saving the overall assembly thickness of the first conductive element 41, the second conductive element 42, and the conductive telescopic element 71 along the X-axis direction.

[0100] In one alternative implementation, please refer to Figure 6 A second groove 111 is provided on the side of the first conductive member 41 facing the second conductive member 42. The other end of the conductive telescopic member 71 abuts against or is fixedly connected to the bottom of the second groove 111. Of course, this embodiment can be combined with the embodiment in which a first groove 110 is provided on the side of the second conductive member 42 facing the first conductive member 41. The opening of the second groove 111 communicates with the opening of the first groove 110 to position the other end of the conductive telescopic member 71. Both the second groove 111 and the first groove 110 can accommodate a portion of the conductive telescopic member 71. The cooperation of the first groove 110 and the second groove 111 allows for the provision of a longer conductive telescopic member 71 while maintaining a small gap between the first conductive member 41 and the second conductive member 42.

[0101] Optional, please refer to Figure 6 and Figure 7The electronic device 100 also includes a sealing ring 67. The sealing ring 67 is made of materials including, but not limited to, rubber, silicone, and other materials with good sealing performance. The sealing ring 67 is fitted onto the peripheral side of the second conductive element 42. The outer contour surface of the sealing ring 67 is in contact with the wall of the first through hole 103 and can slide relative to it. The inner contour surface of the sealing ring 67 is in contact with the peripheral side of the second conductive element 42. The sealing ring 67 itself is made of waterproof material. Thus, the sealing ring 67 is sealed between the peripheral side of the second conductive element 42 and the wall of the first through hole 103, thereby achieving waterproofing between the second conductive element 42 and the housing frame 1, and preventing water from seeping into the circuit assembly 5 through the first through hole 103.

[0102] Furthermore, an annular groove 68 is provided on the outer peripheral surface of the second conductive element 42. This annular groove 68 is used to accommodate the sealing ring 67 to position the sealing ring 67. In addition, the sealing ring 67 is in a compressed state between the second conductive element 42 and the hole wall of the first through hole 103. The second conductive element 42, the sealing ring 67, and the hole wall of the first through hole 103 form an interference fit, which can achieve the 5ATM waterproof requirement, that is, the waterproofness of this component meets the 5ATM atmospheric pressure waterproof level.

[0103] In the second implementation, please refer to Figure 10 and Figure 11 This embodiment improves upon the first embodiment by including an elastic pad 72 in the elastic conductive element 7. The elastic pad 72 abuts between the first conductive element 41 and the second conductive element 42. The material of the elastic pad 72 includes, but is not limited to, elastic silicone, elastic rubber, elastic polymer, etc. The elastic pad 72 may be conductive or non-conductive.

[0104] Please see Figure 10 and Figure 11 The elastic pad 72 is disposed between the first conductive element 41 and the second conductive element 42. Utilizing the compressibility of the elastic pad 72, the first conductive element 41 and the second conductive element 42 can absorb the tolerance zone under the condition of manufacturing error, thus ensuring the stability of the feel of the button assembly 4 during mass production. The setting of the elastic pad 72 can also ensure that under extreme working conditions, the elastic pad 72 is not easily deformed compared to springs, etc., and can absorb more impact force, so that the button assembly 4 can be buffered during collision / drop, so that the button assembly 4 will not fail under collision / drop, and its service life can be guaranteed.

[0105] Furthermore, the elastic pad 72 is in a compressed state. In short, the elastic pad 72 is interference-fitted between the first conductive element 41 and the second conductive element 42, meaning that along the X-axis direction, the elastic pad 72 is pressed between the first conductive element 41 and the second conductive element 42. The elastic pad 72 exerts a compressive resistance force on the first conductive element 41 in the positive X-axis direction, and an excised compressive resistance force on the second conductive element 42 in the negative X-axis direction. This allows the elastic pad 72 to support the first conductive element 41, preventing the button assembly 4 from shaking and improving the stability of the button assembly 4.

[0106] For details, please refer to Figure 12 The elastic pad 72 and the conductive telescopic member 71 are fitted together in the X-axis direction. Optionally, the elastic pad 72 is fitted around the outer periphery of the conductive telescopic member 71. Alternatively, the conductive telescopic member 71 is fitted around the outer periphery of the elastic pad 72. This design reduces the superposition size of the elastic pad 72 and the conductive telescopic member 71 in the X-axis direction, thereby making the structure of the elastic conductive member 7, the first conductive member 41, and the second conductive member 42 more compact. In this embodiment, the elastic pad 72 is located on the side of the first conductive member 41 facing the second conductive member 42. A third groove 113 is provided on the side of the first conductive member 41 facing the second conductive member 42. A second groove 111 is located on the bottom surface of the third groove 113. The elastic pad 72 is located within the third groove 113. On the one hand, the third groove 113 provides space for positioning and receiving the elastic pad 72; on the other hand, the elastic pad 72 is located within the first conductive member 41 to reduce the superposition size of the elastic pad 72 and the first conductive member 41 in the X-axis direction, improving the compactness of the button assembly 4.

[0107] Please see Figure 10 The elastic pad 72 is spaced apart from the bottom surface of the receiving groove 106 on the side facing the second conductive member 42. The orthographic projection of the elastic pad 72 on the side where the second conductive member 42 is located can cover the first through hole 103 to provide a sufficiently large impact absorption area and a larger support area for the first conductive member 41. One end of the second conductive member 42 extending into the receiving groove 106 can abut 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.

[0108] Please see Figure 12 The elastic gasket 72 has a second through hole 109 that communicates with the first through hole 103. Please refer to the following: Figure 10The second through hole 109 can communicate with the first groove 110 and the second groove 111. One end of the conductive telescopic member 71 abuts against or is fixedly connected to the bottom plate of the first groove 110, the conductive telescopic member 71 passes through the second through hole 109, and the other end of the conductive telescopic member 71 abuts against or is fixedly connected to the bottom of the second groove 111. In this way, the conductive telescopic member 71 passes through the second through hole 109 to reduce the overall superposition size of the conductive telescopic member 71 and the elastic pad 72 in the X-axis direction.

[0109] The expansion and contraction of the conductive telescopic component 71 in the X-axis direction and the expansion and contraction of the elastic pad 72 in the X-axis direction can be arranged independently and in parallel. In this way, both the conductive telescopic component 71 and the elastic pad 72 can provide elastic support for the first conductive component 41, so that the button assembly 4 can be stably installed.

[0110] Taking the first conductive component 41 as the keycap and the second conductive component 42 as the key rod as an example, the assembly relationship between the various components in this embodiment is as follows: First, the flexible circuit board 51 is assembled (attached) onto the circuit board support 54; the circuit board support 54 is assembled onto the inner side of the housing frame 1; the sealing ring 67 is pre-fitted into the annular groove 68 of the second conductive component 42; the second conductive component 42 is assembled into the first through hole 103 of the housing frame 1, and one end of the second conductive component 42 abuts against the electrical contact portion 52 of the flexible circuit board 51; the conductive telescopic component 71 is installed into the first groove 110 of the key rod; The first elastic element 65 and the second elastic element 66 are installed in the receiving groove 106. The elastic gasket 72 is pre-processed and assembled in the third groove 113 of the first conductive element 41. The first conductive element 41 is assembled in the receiving groove 106 of the housing frame 1, so that one end of the key rod abuts against the elastic gasket 72 and the conductive telescopic element 71 abuts against the bottom of the second groove 111 of the first conductive element 41. Pre-press so that the hook space of the hook part of the first conductive element 41 corresponds to the insertion hole. Insert the first limiting element 61 and the second limiting element 62 into the two insertion holes 63 and 64 respectively and press them to the bottom to complete the assembly.

[0111] In the third implementation, please refer to Figure 13 The conductive telescopic component 71 can be a ring-shaped component. Specifically, the conductive telescopic component 71 can be a spring. Unlike the second embodiment, a portion of the conductive telescopic component 71 is fitted onto the peripheral side surface of the second conductive component 42. This peripheral side surface faces the wall of the first through hole 103, increasing the contact area between the conductive telescopic component 71 and the second conductive component 42 and improving the reliability of the electrical connection between them. When the conductive telescopic component 71 is fitted onto the peripheral side surface of the second conductive component 42, one end of the conductive telescopic component 71 can be fixedly or slidably connected to the peripheral side surface of the second conductive component 42.

[0112] Further, please refer to Figure 13The second conductive element 42 has a locking post 421 on its peripheral side. The locking post 421 extends radially. One end of the conductive telescopic element 71 engages with the locking post 421. Optionally, the locking post 421 can be annularly arranged on the peripheral side of the second conductive element 42. The conductive telescopic element 71 can be a helical spring, in which case a portion of the helical coil of the conductive telescopic element 71 can be sleeved on the locking post 421. This allows the conductive telescopic element 71 to be connected to the locking post 421 without additional connection methods, and this connection method is detachable and easy to install.

[0113] The other end of the conductive telescopic component 71 abuts against or is fixedly connected to the first conductive component 41. Specifically, the other end of the conductive telescopic component 71 can be fixedly connected to the first conductive component 41 by means of conductive adhesive bonding, welding, pressing, or other connection methods.

[0114] It should be noted that one end of the conductive telescopic member 71 in this embodiment is not limited to being the same as one end of the conductive telescopic member 71 in the first embodiment. In other words, one end of the conductive telescopic member 71 in this embodiment can be the other end of the conductive telescopic member 71 in the first embodiment, or it can be one end of the conductive telescopic member 71 in the first embodiment.

[0115] Furthermore, in this embodiment, the locking post 421 can be formed by forming an annular groove 68 and a thinned post spaced apart along the X-axis on the peripheral side of the columnar second conductive member 42, with the locking post 421 formed between the annular groove 68 and the thinned post. The annular groove 68 is used to accommodate the sealing ring 67. A conductive telescopic member 71 is sleeved on the outer peripheral surface of the thinned post, and one end of the conductive telescopic member 71 is connected to the first conductive member 41.

[0116] Further, please refer to Figure 13 The first conductive element 41 has a second groove 111 on the side facing the second conductive element 42. The end of the second conductive element 42 is located within the second groove 111 and spaced apart from the bottom of the groove. At least a portion of the peripheral surface of the second conductive element 42 is slidably connected to the groove wall of the second groove 111. During the pressing of the conductive telescopic element 71, at least a portion of the second conductive element 42 extends and retracts within the second groove 111. One end of the second conductive element 42 can directly contact the groove wall of the second groove 111 of the first conductive element 41. The second conductive element 42 remains connected to the first conductive element 41, improving the electrical contact stability between them.

[0117] Optionally, the elastic gasket 72 may not be provided between the first conductive element 41 and the second conductive element 42.

[0118] Optional, please refer to Figure 13An elastic gasket 72 may be provided between the first conductive element 41 and the second conductive element 42. Specifically, the elastic gasket 72 has a second through hole 109, which communicates with the second groove 111. The second conductive element 42 passes through the second through hole 109. Optionally, the conductive telescopic element 71 may pass through the second through hole 109, that is, the second conductive element 42, the conductive telescopic element 71, and the elastic gasket 72 are arranged sequentially from the inside to the outside in the Y-axis direction. Further optionally, the conductive telescopic element 71 may be connected to the elastic gasket 72, so that the impact absorption capacity of the elastic gasket 72 and the conductive telescopic element 71 is superimposed in the X-axis direction. Specifically, the conductive telescopic component 71 is a spring, which can be inserted into the elastic pad 72; or, the elastic pad 72 is engaged between two adjacent spiral coils of the conductive telescopic component 71 to fix the elastic pad 72 to the conductive telescopic component 71, thereby improving the connection stability between the elastic pad 72 and the conductive telescopic component 71. Furthermore, the conductive telescopic component 71 and the elastic pad 72 are stacked in the X-axis direction so that the impact absorption capacity of the elastic pad 72 and the conductive telescopic component 71 is superimposed in the X-axis direction.

[0119] Of course, the conductive telescopic member 71 can be inserted into the elastic gasket 72; or, the elastic gasket 72 can be engaged between two adjacent spiral coils of the conductive telescopic member 71, and can also be adapted to other embodiments of this application to obtain new embodiments.

[0120] In the fourth implementation, please refer to Figure 14 This embodiment is similar to the third embodiment, except that this embodiment does not have the conductive telescopic member 71 described in the third embodiment, but only has an elastic structure 78. The elastic structure 78 provides elastic support and elastic recovery force between the locking post 421 of the first conductive member 41 and the second conductive member 42.

[0121] Please see Figure 14 The elastic structure 78 has a third through hole 781. The elastic structure 78 can be a spring or an elastic washer, etc.

[0122] Please see Figure 14The second conductive element 42 may have a protrusion 422 on the side facing the first conductive element 41. The first conductive element 41 may have a groove 414 corresponding to the protrusion 422 on the side facing the second conductive element 42. The groove 414 communicates with the third through hole 781. The protrusion 422 passes through the third through hole 781. The end face of the protrusion 422 is opposite to and spaced apart from the bottom wall of the groove 414. The peripheral side of the protrusion 422 is slidably connected to the peripheral side wall of the groove 414, so that the first conductive element 41 and the second conductive element 42 are slidably connected in the X-axis direction, and the first conductive element 41 and the second conductive element 42 can maintain contact, thereby conducting between the first conductive element 41 and the second conductive element 42, increasing the electrical connection stability between the first conductive element 41 and the second conductive element 42, and the elastic structure does not need to be a conductive structure. In addition, the positions of the protrusion 422 and the groove 414 can be interchanged.

[0123] For the fifth implementation method, please refer to [link / reference]. Figure 15 This embodiment is largely similar to the third embodiment, with the conductive telescopic member 71 being annular and abutting between the first conductive member 41 and the second conductive member 42, etc. However, the difference lies in that the elastic gasket 72 passes through the axial hole of the conductive telescopic member 71. Specifically, the elastic gasket 72 is compressed within the second groove 111 of the first conductive member 41 and the first groove 110 of the second conductive member 42. Thus, the elastic gasket 72 does not need to be located on the periphery of the conductive telescopic member 71; the elastic gasket 72 fully utilizes the internal space of the conductive telescopic member 71, increasing the compactness of the arrangement of the elastic gasket 72 and the conductive telescopic member 71.

[0124] For the sixth implementation method, please refer to [link / reference]. Figure 16 The elastic conductive element 7 includes an elastic matrix 73 and a plurality of conductive substrates 74. The conductive substrates 74 are doped within the elastic matrix 73. The conductive substrates 74 enable the elastic conductive element 7 to be conductive at least in the X-axis direction. The elastic conductive element 7 can be a conductive rubber pad. The elastic substrates can be rubber pads, silicone pads, polyvinyl alcohol elastomers, or other elastomers. The conductive substrates 74 can be conductive metal particles, conductive metal wires, conductive metal filaments, conductive metal meshes, graphene, etc. Conductive metals include copper, gold, silver, aluminum, etc.

[0125] Please see Figure 17 An elastic conductive element 7, which is both elastic and conductive, is disposed in the third groove 113 of the first conductive element 41, so that elastic contact and electrical connection can be realized between the first conductive element 41 and the second conductive element 42. The elastic conductive element 7 provided in this embodiment can be a block, which occupies little space, is easy to install and has good stability.

[0126] For the seventh implementation method, please refer to Figure 18The elastic conductive element 7 also includes an elastic main body portion 75 and a conductive cover portion 76. The elastic main body portion 75 can be a rubber gasket, a silicone gasket, a polyvinyl alcohol elastomer, or other elastomers, etc.

[0127] Please see Figure 18 The elastic main body 75 includes a first surface 751 and a second surface 752 disposed opposite to each other. A portion of the conductive cover 76 is located on the first surface 751 and connected to the first conductive member 41. Another portion of the conductive cover 76 is located on the second surface 752 and connected to the second conductive member 42. The conductive cover 76 is a conductive metal layer, conductive metal foil, etc. The conductive metal is such as copper, gold, silver, aluminum, etc.

[0128] Specifically, the first surface 751 of the elastic main body 75 abuts against the first conductive member 41, so that a portion of the conductive cover 76 contacts the first conductive member 41. The second surface 752 of the elastic main body 75 abuts against the second conductive member 42, so that another portion of the conductive cover 76 contacts the second conductive member 42. Electrical conductivity exists between the portion of the conductive cover 76 and the other portion of the conductive cover 76. This achieves elastic contact and electrical connection between the first conductive member 41 and the second conductive member 42. In this embodiment, the conductive cover 76 is a thin layer, which makes the elastic conductive member 7 occupy less space, easy to install, and has good stability.

[0129] Furthermore, the conductive cover 76 is a flexible conductive film. The flexible conductive film is stretchable to accommodate the expansion and contraction of the elastic main body 75. The flexible conductive film may be a stretchable adhesive layer doped with a plurality of conductive substrates 74. The conductive substrates 74 may be conductive metal particles, conductive metal wires, conductive metal filaments, conductive metal meshes, graphene, etc. Conductive metals include copper, gold, silver, aluminum, etc. The conductive cover 76 may completely or partially cover the outer peripheral surface of the elastic main body 75; alternatively, the conductive cover 76 may spirally surround the outer peripheral surface of the elastic main body 75, so that the conductive cover 76 can accommodate the expansion and contraction of the elastic main body 75 without breaking.
