Description

Technical Field

[0001] This application belongs to the field of electronic device technology, specifically relating to a button and an electronic device. Background Technology

[0002] In related technologies, the buttons of electronic devices usually use a combination of keycaps and dome switches. When the user presses the keycap, the keycap moves toward the dome and deforms the dome. When the dome deforms to a set value, the corresponding function is triggered. In order to reduce the probability of accidental touch, the dome deformation setting value is usually set to be large. This results in a large travel of the button, which can easily lead to problems such as key jamming, play, and dome collapse. Utility Model Content

[0003] The purpose of this application is to provide a button and an electronic device that can effectively solve the technical problem that the button is prone to jamming and misalignment due to its large travel distance.

[0004] In a first aspect, embodiments of this application provide a button, including:

[0005] Piezoelectric components;

[0006] A pressure sensing component is located on one side of the piezoelectric component;

[0007] The keycap assembly is located on the side of the pressure sensing assembly that is opposite to the piezoelectric assembly;

[0008] The piezoelectric component is used to generate vibration when the pressure detection component detects that the keycap assembly is under pressure, thereby providing force feedback.

[0009] As one possible implementation, the pressure detection component includes:

[0010] The first reinforcing member is located on one side of the piezoelectric assembly;

[0011] The second reinforcing member is located on the side of the first reinforcing member that is away from the piezoelectric assembly;

[0012] A pressure sensor is disposed between the first reinforcing member and the second reinforcing member.

[0013] In one possible implementation, at least one of the first and second reinforcing members has a receiving groove, and at least a portion of the pressure sensor is disposed within the receiving groove.

[0014] As one possible implementation, the piezoelectric component includes:

[0015] Piezoelectric ceramic is disposed on the side of the pressure sensing component away from the keycap assembly;

[0016] The bracket is positioned on the side of the piezoelectric ceramic away from the pressure sensing component;

[0017] Among them, piezoelectric ceramics are used to generate vibration when the pressure detection component detects that the keycap assembly is under pressure.

[0018] As one possible implementation, the piezoelectric component further includes:

[0019] The counterweight is mounted on the support, and the counterweight and the piezoelectric ceramic are mounted on the same side of the support.

[0020] As one possible implementation, the surface area of ​​the piezoelectric ceramic facing the pressure sensing component is smaller than the surface area of ​​the pressure sensing component facing the piezoelectric ceramic.

[0021] As one possible implementation, the keycap assembly includes:

[0022] Plastic keycaps are placed on the side of the pressure sensing component that faces away from the piezoelectric component;

[0023] Metal keycaps are connected to plastic keycaps, with at least a portion of the plastic keycaps located between the metal keycaps and the pressure sensing components.

[0024] As one possible implementation, plastic keycaps are injection molded onto metal keycaps, the metal keycaps having a rubber-stretched structure, and the plastic keycaps covering the rubber-stretched structure.

[0025] As one possible implementation, it also includes:

[0026] A sealing ring is located around the periphery of the keycap assembly.

[0027] Secondly, embodiments of this application provide an electronic device, including:

[0028] The frame has mounting holes; and

[0029] As provided in the first aspect embodiment, the button is fixed to the frame, at least a portion of the keycap assembly in the button is located within the mounting hole, and there is a gap between the pressure sensing component in the button and the frame.

[0030] In this embodiment, the button includes a piezoelectric component, a pressure detection component, and a keycap assembly. The pressure detection component is used to collect the position and magnitude of the pressure, and the piezoelectric component is used to provide vibration to simulate force feedback. The pressure detection component is located on one side of the piezoelectric component, and the keycap assembly is located on the side of the pressure detection component away from the piezoelectric component. When the user touches the keycap assembly, the keycap assembly deforms or moves towards the pressure detection component, thereby causing the pressure detection component to deform. This allows the electronic device to determine the current pressing position and pressure. Furthermore, by utilizing the characteristic of the piezoelectric component to deform when energized, the piezoelectric component deforms towards the pressure detection component, thereby achieving vibration of the piezoelectric component and achieving the effect of force feedback, thus realizing the function of the button.

[0031] As mentioned above, since the key can detect touch pressure through the pressure detection component and then provide force feedback through the piezoelectric component, the keycap assembly does not need a large travel distance, or even the keycap assembly does not need to move, only to deform. This reduces the possibility of key jamming and play.

[0032] Furthermore, since the pressure detection component can detect touch pressure, multiple trigger thresholds can be set for the button, allowing users to achieve different functions through different pressing methods such as light or heavy presses, thus enriching the button's functionality.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] The following is combined with Figures 1 to 6 This application describes a button 100 and an electronic device 200 according to embodiments thereof.

[0047] Firstly, such as Figure 1 and Figure 2 As shown, this application embodiment provides a button 100, including: a piezoelectric component 110; a pressure detection component 120 disposed on one side of the piezoelectric component 110; and a keycap assembly 130 disposed on the side of the pressure detection component 120 opposite to the piezoelectric component 110; wherein, the piezoelectric component 110 is used to generate vibration when the pressure detection component 120 detects that the keycap assembly 130 is pressed, thereby providing force feedback.

[0048] In this embodiment, the button 100 includes a piezoelectric component 110, a pressure detection component 120, and a keycap assembly 130. The pressure detection component 120 is used to collect the position and magnitude of the pressure, and the piezoelectric component 110 is used to provide vibration to simulate force feedback. The pressure detection component 120 is located on one side of the piezoelectric component 110, and the keycap assembly 130 is located on the side of the pressure detection component 120 away from the piezoelectric component 110. When the user touches the keycap assembly 130, the keycap assembly 130 deforms or moves towards the pressure detection component 120, thereby causing the pressure detection component 120 to deform. This allows the electronic device 200 to determine the current pressing position and pressing force. Furthermore, by utilizing the characteristic of the piezoelectric component 110 to deform when energized, the piezoelectric component 110 deforms towards the pressure detection component 120, thereby achieving vibration of the piezoelectric component 110 and achieving the effect of force feedback, thus realizing the function of the button 100.

[0049] As mentioned above, since the key 100 can detect touch pressure through the pressure detection component 120 and then provide force feedback through the piezoelectric component 110, the keycap component 130 does not need a large travel distance, or even the keycap component 130 does not need to move, only to deform. This reduces the possibility of key 100 malfunctioning such as key jamming and play.

[0050] Furthermore, since the pressure detection component 120 can detect touch pressure, the button 100 can be set with multiple trigger thresholds, allowing users to achieve different functions through different pressing methods such as light pressing or heavy pressing, thus enriching the functions of the button 100.

[0051] When the keycap is subjected to force, it deforms, triggering the pressure detection component 120. The pressure sensor 126 detects the pressure value, and the electronic device 200 can determine the control parameters of the piezoelectric component 110 based on the pressure value. Then, it controls the piezoelectric component 110 to deform and generate vibration, thereby realizing simulated force feedback.

[0052] Furthermore, the piezoelectric component 110 can be bonded to the pressure detection component 120 via the first adhesive 150, and the pressure detection component 120 can be bonded to the keycap assembly 130 via the second adhesive 160.

[0053] like Figure 2 As shown, in one possible implementation, the pressure detection assembly 120 includes: a first reinforcing member 122 located on one side of the piezoelectric assembly 110; a second reinforcing member 124 located on the side of the first reinforcing member 122 away from the piezoelectric assembly 110; and a pressure sensor 126 disposed between the first reinforcing member 122 and the second reinforcing member 124.

[0054] Specifically, the pressure detection assembly 120 includes a first reinforcing member 122, a second reinforcing member 124, and a pressure sensor 126. The pressure sensor 126 is disposed between the first reinforcing member 122 and the second reinforcing member 124. The first reinforcing member 122 is disposed on one side of the piezoelectric assembly 110, and the second reinforcing member 124 is disposed on the side of the pressure sensor 126 away from the first reinforcing member 122. The pressure sensor 126 is protected by the first reinforcing member 122 and the second reinforcing member 124.

[0055] When the keycap is subjected to force, it deforms, causing the second reinforcing member 124 to deform as well. The second reinforcing member 124 presses against the pressure sensor 126, causing the pressure sensor 126 to detect the pressure value. The electronic device 200 can determine the control parameters of the piezoelectric component 110 based on this pressure value, and then control the piezoelectric component 110 to vibrate, thereby achieving force feedback. Furthermore, when the piezoelectric component 110 vibrates, it can strike the first reinforcing member 122, thereby increasing the force feedback.

[0056] As described above, the piezoelectric component 110 in this application can provide active force feedback, and the pressure detection component 120 can detect specific pressure values, thereby determining the user's pressing position and the magnitude of the pressing force on the button 100. Specifically, when the user presses or slides the button 100 at different positions, the pressure detection component 120 deforms to different degrees, thereby generating different electrical signals. The electronic device 200 can detect sliding, light pressing, and heavy pressing based on these electrical signals, which is beneficial to the user. When reading or taking pictures, the user can use the button 100 to quickly turn pages, zoom in or out, etc.

[0057] When a user slides on key 100, the pressure generated will move on pressure detection component 120, thereby generating a corresponding electrical signal to determine the user's sliding operation. The deformation generated by piezoelectric component 110 is localized, so that the force feedback of key 100 is concentrated at the keycap component 130, achieving fast feedback and improving the user experience.

[0058] The first reinforcing member 122 can be a metal sheet, such as a steel sheet or an aluminum alloy sheet. Similarly, the second reinforcing member 124 can be a metal sheet, such as a steel sheet or an aluminum alloy sheet.

[0059] like Figure 2 As shown, in one possible implementation, at least one of the first reinforcing member 122 and the second reinforcing member 124 has a receiving groove 128, and at least a portion of the pressure sensor 126 is disposed within the receiving groove 128.

[0060] Specifically, the first reinforcement 122 has a receiving groove 128, in which at least a portion of the pressure sensor 126 is disposed, thereby protecting the pressure sensor 126.

[0061] The first reinforcing member 122 and the pressure sensor 126 are bonded together with an adhesive.

[0062] Alternatively, the second reinforcement 124 may have a receiving groove 128, in which at least a portion of the pressure sensor 126 is disposed, thereby protecting the pressure sensor 126.

[0063] The second reinforcing member 124 and the pressure sensor 126 are bonded together with an adhesive.

[0064] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in one possible implementation, the piezoelectric component 110 includes: a piezoelectric ceramic 112 disposed on the side of the pressure detection component 120 away from the keycap assembly 130; and a bracket 114 disposed on the side of the piezoelectric ceramic 112 away from the pressure detection component 120; wherein the piezoelectric ceramic 112 is used to generate vibration when the pressure detection component 120 detects that the keycap assembly 130 is under pressure.

[0065] Specifically, the piezoelectric component 110 includes a piezoelectric ceramic 112 and a bracket 114. The piezoelectric ceramic 112 is disposed on the side of the pressure detection component 120 away from the keycap assembly 130. The piezoelectric ceramic 112 is used to generate vibration when the pressure detection component 120 detects that the keycap assembly 130 is under pressure. The vibration generated by the piezoelectric ceramic 112 being energized can be reflected in the pressure detection component 120 and then in the keycap assembly 130. The bracket 114 is disposed on the side of the piezoelectric ceramic 112 away from the pressure detection component 120, thereby achieving the function of fixing the piezoelectric ceramic 112.

[0066] The bracket 114 can be made of metal sheet, plastic sheet or polymer sheet material, such as steel sheet, aluminum alloy sheet or carbon fiber sheet, thereby reducing the size of the bracket 114 and facilitating the assembly of the button 100 in the electronic device 200.

[0067] Optionally, the bracket 114 has a through hole 1142 for mounting and fixing the bracket 114 in the electronic device 200.

[0068] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, optionally, the piezoelectric assembly 110 also includes a piezoelectric circuit board 118 electrically connected to the piezoelectric ceramic 112. The piezoelectric circuit board 118 is used to electrically connect to the circuit board in the electronic device 200. When the piezoelectric ceramic 112 is energized, it will deform, thereby realizing force feedback.

[0069] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in one possible implementation, the piezoelectric assembly 110 further includes a counterweight 116 disposed on the bracket 114, with the counterweight 116 and the piezoelectric ceramic 112 disposed on the same side of the bracket 114.

[0070] Specifically, the piezoelectric component 110 also includes a counterweight 116, which is mounted on the bracket 114. The counterweight 116 and the piezoelectric ceramic 112 are mounted on the same side of the bracket 114. The counterweight 116 increases the mass of the piezoelectric component 110, thereby increasing the vibration effect and strengthening the force feedback of the button 100.

[0071] Among them, such as Figure 2 As shown, the counterweight 116 and the piezoelectric ceramic 112 are distributed along the length direction AB of the bracket 114. Thus, when the piezoelectric ceramic 112 deforms and vibrates, the counterweight 116 and the piezoelectric ceramic 112 vibrate together, improving the force feedback effect of the button 100.

[0072] like Figure 2 , Figure 4 and Figure 5 As shown, in one possible implementation, the surface area of ​​the piezoelectric ceramic 112 facing the pressure detection component 120 is smaller than the surface area of ​​the pressure detection component 120 facing the piezoelectric ceramic 112.

[0073] Specifically, the surface area of ​​the piezoelectric ceramic 112 facing the pressure detection component 120 is smaller than the surface area of ​​the pressure detection component 120 facing the piezoelectric ceramic 112, thus making the pressure detection component 120 partially suspended relative to the piezoelectric ceramic 112. Specifically, the piezoelectric ceramic 112 can be positioned opposite the middle of the pressure detection component 120, making the pressure sensor easier to bend, improving the pressure detection accuracy of the pressure sensor, and reducing the minimum threshold that the pressure sensor can detect.

[0074] like Figure 2 As shown, in one possible implementation, the keycap assembly 130 includes: a plastic keycap 132 disposed on the side of the pressure sensing assembly 120 away from the piezoelectric assembly 110; and a metal keycap 134 connected to the plastic keycap 132, with at least a portion of the plastic keycap 132 located between the metal keycap 134 and the pressure sensing assembly 120.

[0075] Specifically, the keycap assembly 130 includes a plastic keycap 132 and a metal keycap 134. The plastic keycap 132 is disposed on the side of the pressure sensing assembly 120 away from the piezoelectric assembly 110, and the metal keycap 134 is disposed on the plastic keycap 132. The metal keycap 134 and the plastic keycap 132 are connected, and at least part of the plastic keycap 132 is located between the metal keycap 134 and the pressure sensing assembly 120. After the keycap 100 is assembled on the electronic device 200, the clearance requirements of the antenna of the electronic device 200 can be met.

[0076] Since metal is a conductor, it has a significant impact on antenna performance. Therefore, the keycap assembly 130 is divided into two parts.

[0077] like Figure 2 As shown, in one possible implementation, the plastic keycap 132 is injection molded onto the metal keycap 134, the metal keycap 134 has a rubber-pull structure 136, and the plastic keycap 132 is wrapped around the rubber-pull structure 136.

[0078] Specifically, the plastic keycap 132 is injection molded onto the metal keycap 134, the metal keycap 134 has a rubber-pull structure 136, and the plastic keycap 132 is wrapped around the rubber-pull structure 136, thereby improving the connection strength between the metal keycap 134 and the rubber keycap and reducing the possibility of the keycap assembly 130 cracking.

[0079] The adhesive-stretching structure 136 can be at least one columnar structure or other structures.

[0080] The metal keycap 134 and the plastic keycap 132 can be made by nano-injection molding or insert injection molding to meet the clearance requirements of the antenna.

[0081] like Figure 1 and Figure 2 As shown, as one possible implementation, it also includes a sealing ring 140 disposed around the periphery of the keycap assembly 130.

[0082] Specifically, the button 100 also includes a sealing ring 140 disposed on the keycap assembly 130, thereby improving the sealing effect of the button 100. When the button 100 is installed in the electronic device 200, the sealing ring 140 abuts against the frame 210 of the electronic device 200.

[0083] The sealing ring 140 can be a silicone ring, which can achieve dust and water resistance and reduce the risk of the conventional physical button 100 getting stuck or getting wet.

[0084] Alternatively, the sealing ring 140 can be disposed on the keycap assembly 130 by means of liquid injection molding or insert molding, so that the electronic device 200 can meet the IPX8 waterproof rating.

[0085] like Figure 1 As shown, in one possible implementation, the pressure detection assembly 120 also includes a pressure sensor circuit board 1262, which is electrically connected to the circuit board in the electronic device 200 to transmit the electrical signal generated by the pressure sensor 126 under pressure to the circuit board of the electronic device 200.

[0086] The key 100 provided in this application mainly includes three parts: a keycap assembly 130, a pressure detection assembly 120, and a piezoelectric assembly 110. The keycap assembly 130 is mainly used to protect the pressure detection assembly 120 and provide an appearance. The pressure detection assembly 120 is mainly used to detect the user's pressing position and pressure. The piezoelectric assembly 110 is mainly used to simulate force feedback through vibration. The pressure detection assembly 120 collects the signal of external pressure to identify the action of the human hand. The processor of the electronic device 200 controls the deformation and vibration of the piezoelectric ceramic in the piezoelectric assembly 110 to generate force feedback, so that the vibration of the entire piezoelectric assembly 110 is transmitted to the keycap through the pressure detection assembly 120 to realize force feedback.

[0087] Secondly, such as Figure 3 , Figure 4 and Figure 5 As shown, this application provides an electronic device 200, including: a frame 210 having a mounting hole 212; and a button 100 as provided in the first aspect embodiment, the button 100 being fixed to the frame 210, at least a portion of the keycap assembly 130 in the button 100 being located within the mounting hole 212, and a gap 230 being between the pressure sensing assembly 120 in the button 100 and the frame 210.

[0088] In the embodiments of this application, the electronic device 200 includes the button 100 as provided in the first aspect embodiment, and therefore has all the beneficial effects of the button 100 as provided in the first aspect embodiment, which will not be described in detail here.

[0089] Specifically, the frame 210 has a mounting hole 212, and the keycap assembly 130 is assembled in the mounting hole 212 of the frame 210, with an assembly gap 230 between them. The pressure sensor 126 is fixed in the first reinforcing member 122 and the second reinforcing member 124. The pressure sensor 126, the first reinforcing member 122 and the second reinforcing member 124 can be fixed by adhesive. Furthermore, the edge of the pressure sensor 126 is designed to be suspended, which facilitates the deformation of the second reinforcing member 124. The function of the pressure sensor 126 is to detect the deformation of the second reinforcing member 124.

[0090] The entire pressure detection assembly 120 is fixed to the bottom of the keycap assembly 130 using a second colloid 160. The piezoelectric ceramic 112 and the counterweight 116 are fixed to the bracket 114 using adhesive. One section of the bracket 114 is fixed to the frame 210. The piezoelectric assembly 110 is in close contact with the first reinforcing member 122 of the pressure detection assembly 120. The function of the piezoelectric ceramic 112 is to deform and vibrate when energized, generating force feedback. The counterweight 116 is placed at the head of the bracket 114 and amplifies the force feedback of the piezoelectric ceramic together with the bracket 114.

[0091] Optionally, the frame 210 has a screw hole 214. After the bracket 114 is installed on the frame 210, the button 100 can be fixed by passing a screw 220 through the through hole 1142 on the bracket 114 and screwing it into the screw hole 214.

[0092] Figure 6 A flowchart illustrating the user's press and force feedback of an electronic device according to an embodiment of this application is shown, as follows: Figure 6 As shown, the process by which electronic devices handle user presses and force feedback is as follows:

[0093] Step 602: The user presses the keycap assembly;

[0094] Step 604: The second reinforcement in the pressure detection assembly deforms;

[0095] Step 606: The pressure sensor in the pressure detection assembly detects the deformation of the second reinforcement and outputs a pressure signal;

[0096] Step 608: The processor processes the linear pressure-sensitive signal;

[0097] Step 610: Output control signal to piezoelectric component;

[0098] Step 612: The deformation of the piezoelectric component causes the counterweight and support to vibrate;

[0099] Step 614: The piezoelectric component vibrates and impacts the pressure detection component, and transmits the force feedback to the keycap component.

[0100] Specifically, such as Figure 5 As shown, when a user presses the keycap assembly 130 or slides on the keycap assembly 130, the pressure F is transmitted through the keycap assembly 130 to the second reinforcing member 124 of the pressure detection assembly 120, causing the second reinforcing member 124 to deform. The pressure sensor 126 in the pressure detection assembly 120 detects the different deformation amounts and deformation times of the second reinforcing member 124, and transmits the corresponding pressure-sensitive signals to the processor of the electronic device 200 for processing. Then, the processor of the electronic device 200 outputs different electrical signals to the piezoelectric assembly 110 to generate deformation vibration, thereby generating force feedback.

[0101] Since the pressure and duration of the user pressing or sliding on the keycap assembly 130 are different, the pressure sensor 126 can identify different ways of pressing the keycap assembly 130 by the deformation of the second reinforcing member 124, and output different electrical signals to the piezoelectric ceramic, thereby controlling the force and frequency of the piezoelectric assembly 110.

[0102] As described above, piezoelectric ceramics drive the counterweight 116 to vibrate and impact the pressure detection component 120. The pressure detection component 120 then transmits the vibration to the keycap assembly 130, thereby generating force feedback. The force feedback generated by this key 100 design is similar to that of a physical key. The piezoelectric ceramic 112 has a fast response speed, thus enabling rapid response. Furthermore, the force of the piezoelectric ceramic 112 is localized, concentrating the force feedback from the key 100 at the keycap assembly 130, with virtually no feedback at other locations, improving the user experience. At the same time, the structure of the key 100 meets IPX8 waterproof performance and antenna clearance requirements.

[0103] Compared with buttons in related technologies, this application uses a piezoelectric component 110 to simulate active force feedback instead of physical elastic passive force feedback. In addition to simply recognizing whether a button is pressed in related technologies, it adds the recognition of the pressing force intensity, which can realize multi-functional detection of sliding, light pressing and heavy pressing.

[0104] In this context, electronic device 200 can be a terminal or other devices besides electronic device 200. For example, electronic device 200 can be a mobile phone, tablet computer, laptop computer, PDA, in-vehicle electronic device, music playback device, private network communication terminal equipment (such as a walkie-talkie), mobile internet device (MID), augmented reality / virtual reality / mixed reality device, robot, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. It can also be a server, network attached storage (NAS), personal computer (PC), television (TV), ATM, or self-service machine, etc. This application embodiment does not specifically limit the scope of the device.

[0105] In the description of this specification, references to terms such as "an embodiment" or "specific embodiment" indicate that a particular feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0106] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
