Description

Technical Field

[0001] This utility model relates to the field of electronic devices, and in particular to a silent button structure and electronic device. Background Technology

[0002] Mechanical buttons are crucial components in electronic devices, used to control switching or adjusting settings. However, existing mechanical button structures have the following drawbacks: both the button and the PCB are made of rigid materials, resulting in a stiff tactile feel when the button is pressed against the PCB. Furthermore, the lack of a buffer zone between the button and the PCB leads to significant noise during direct contact or separation. Additionally, positive dimensional tolerances in the rigid material of the button and PCB can easily cause interference and jamming, leading to button malfunction. Utility Model Content

[0003] Therefore, it is necessary to provide a silent button structure and electronic device to address the issues of a hard feel and significant noise generated when the button contacts the PCB board.

[0004] A silent button structure includes: a PCB board; a response contact disposed on the PCB board; a button assembly facing the response contact, the button assembly being movable relative to the response contact, the button assembly having at least a first position and a second position when moving relative to the response contact, the button assembly applying a force F1 to the response contact or separating from the response contact when the button assembly is in the first position, the button assembly applying a force F2 to the response contact when the button assembly is in the second position, the F2 being greater than the F1; and a protective cover disposed on the response contact and / or the button assembly, the protective cover being located between the response contact and the button assembly.

[0005] The first aspect of this application discloses a silent button structure. Through the arrangement of the PCB board and the response contact, the movement of the button assembly can control the power on / off and speed adjustment functions of a product equipped with this silent button structure. For example, when the button assembly is in the first position, it controls the power off of the product; when the button assembly is in the second position, it controls the power on of the product. A protective cover is placed on the response contact, located between the response contact and the button assembly. The protective cover is made of a soft material, essentially acting as a protective sleeve on the response contact, thereby reducing the harsh feel when the button assembly and the response contact make contact, resulting in a better user experience. This design effectively reduces noise generated when the button assembly and the response contact make contact. Furthermore, the dimensional tolerance between the PCB board and the response contact can be positive. This positive tolerance can be offset by the slight deformation of the protective cover, ensuring a tight fit between the button assembly, the protective cover, and the response contact. The button assembly will not jam and fail, allowing for greater design flexibility and a more compact overall structure. This product can be widely used in household appliances such as televisions, air conditioners, refrigerators, audio equipment, and hair dryers, and has a wide range of applications.

[0006] In one embodiment, the protective cover is fitted over the response contact. By fitting the protective cover over the response contact, the button assembly first contacts the protective cover during button press. Because the protective cover is made of a soft material, it effectively cushions the pressure applied by the button assembly, thereby reducing the harshness between the button assembly and the response contact. This design makes button operation smoother and softer, greatly improving operational comfort.

[0007] In one embodiment, the protective cover is fitted over the button assembly. By fitting the protective cover over the button assembly, the harshness of contact between the button assembly and the response contacts can be effectively reduced, providing a softer tactile feel. This design is particularly suitable for prolonged use, reducing hand discomfort and fatigue.

[0008] In one embodiment, the button assembly is positioned opposite the response contact. This positioning allows the user to directly and accurately trigger the response contact when pressing the button assembly. This design simplifies the operation process and improves convenience and efficiency.

[0009] In one embodiment, the button assembly includes a pressure post, a pressing portion, and a limiting member. The pressure post is disposed opposite to the response contact. When the button assembly is in the first position, the pressure post applies the force F1 to the response contact; when the button assembly is in the second position, the pressure post applies the force F2 to the response contact. The pressing portion is disposed on the pressure post, and the limiting member is disposed on the pressing portion. The limiting member and the pressure post are located on the same side of the pressing portion. The pressure post ensures good contact with the response contact, resulting in a fast response speed. The limiting member restricts the movement range of the button assembly when the product is mounted on an electronic device, preventing the product from detaching from the electronic device. This design improves the product's durability and reliability.

[0010] In one embodiment, the protective cover is fitted over the pressure post. By fitting the protective cover over the pressure post, the noise generated when the pressure post contacts the response contact can be reduced. Furthermore, it effectively reduces wear caused by direct contact between the pressure post and the response contact. This protective effect helps extend the service life of the pressure post and improves the overall reliability of the product.

[0011] In one embodiment, the length of the pressure post is greater than or equal to the length of the limiting member. By making the length of the pressure post greater than or equal to the length of the limiting member, the design is more reasonable. While ensuring effective contact and separation between the button assembly and the response contact, it also ensures a shorter movement distance for the button assembly, limiting the movement range of the button assembly, thereby making operation simpler.

[0012] In one embodiment, the limiting member includes a limiting plate and a protrusion. The limiting plate is disposed on the pressing part, and the protrusion is disposed on the limiting plate at the end of the limiting plate away from the pressing part. The protrusion is used to abut against an external device. The limiting plate provides stable support for the protrusion by providing it with the protrusion. The protrusion limits the range of movement of the button assembly, preventing the button assembly from detaching from the device, thereby improving the usability of the button assembly.

[0013] In one embodiment, there are multiple limiting members, all disposed on the pressing part and located on the same side of the pressing part. Each of the multiple limiting members has a protrusion with a different orientation. The multiple limiting members better prevent the button assembly from detaching from the device, improving the product's durability and reliability. The different orientations of the protrusions allow them to abut against external devices, limiting the movement range of the button assembly and preventing it from detaching. Furthermore, it reduces the wear on individual protrusions. This design helps extend the overall lifespan of the button assembly.

[0014] In one embodiment, the protective cover has a Shore hardness of 65-70. This Shore hardness range provides the protective cover with moderate flexibility. When the user presses the button assembly, the protective cover can undergo a certain degree of elastic deformation, preventing an overly harsh feel. Compared to protective covers with excessive hardness, it offers a softer touch, reducing the impact on the user's fingers and making operation more comfortable, especially suitable for scenarios involving prolonged use of button devices.

[0015] In one embodiment, the protective cover has a thickness of 1-2 mm. This thickness range prevents the cover from being excessively bulky, allowing for rapid transfer of pressure to the response contacts when the user presses the button assembly, reducing pressing delay and making operation more responsive. Furthermore, it avoids excessive resistance to the user's fingers, resulting in smoother pressing operation.

[0016] In one embodiment, the protective cover is made of silicone material. By being made of silicone, the protective cover possesses excellent softness and elasticity. When a user presses the button, the protective cover can elastically deform, providing an extremely comfortable tactile experience for the fingers and greatly improving user comfort.

[0017] In one embodiment, the responsive contact includes a first contact head and a second contact head. The first contact head is disposed on the PCB board, and the second contact head is disposed on the first contact head. The button assembly can apply the forces F1 and F2 to the second contact head, and the protective cover is fitted onto the second contact head. The distribution of the first and second contact heads allows the protective cover to fit more effectively onto the second contact head while preventing it from contacting the PCB board and affecting its performance.

[0018] An electronic device includes: a housing assembly having a perforation; an electrical structure disposed on and inside the housing assembly; and the aforementioned silent button structure, wherein a PCB board is disposed on the electrical structure, the button assembly is disposed on the housing assembly and located at the perforation, the button assembly is movable relative to the housing assembly, and when the button assembly moves relative to the housing assembly, it has at least a first position and a second position; when the button assembly is in the first position, the electrical structure is in a first state, and when the button assembly is in the second position, the electrical structure is in a second state.

[0019] The second aspect of this application discloses an electronic device in which a button assembly corresponds to different working states of the electrical structure at different positions. Users can easily switch between different functional states according to their needs, such as switching from standby state (first state) to working state (second state), making operation simple and intuitive. This precise control helps ensure the effective execution of device functions and avoids functional malfunctions caused by inaccurate button operation. Furthermore, the silent button structure is located at the perforation, and its compact design ensures that the buttons do not appear obtrusive, contributing to a clean and aesthetically pleasing design that meets the high aesthetic demands of modern consumers for electronic devices.

[0020] In one embodiment, a protrusion is formed on the button assembly, located inside the housing assembly, and the protrusion can abut or separate from the housing assembly. By abutting against the housing assembly with the protrusion, the movement of the button assembly reaches its maximum stroke, which restricts the degree of freedom of the button assembly, thereby preventing the button assembly from detaching from the electronic device and improving the durability of the product.

[0021] In one embodiment, when the button assembly is in the first position, the protrusion abuts against the housing assembly; when the button assembly is in the second position, the protrusion separates from the housing assembly. By abutting or separating the protrusion from the housing assembly, the button assembly can control the functions of the electronic device while preventing it from detaching from the housing assembly.

[0022] In one embodiment, there are two protrusions, both of which can abut or separate from the housing assembly, and the two protrusions face opposite directions. By having the two protrusions face opposite directions, local stress concentration that could be caused by excessive force on a single protrusion is avoided, thereby reducing the risk of damage to the button assembly's own structure and further improving the reliability of the entire button structure.

[0038] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0040] Example 1

[0041] like Figure 1-3As shown, this embodiment discloses a silent button structure, including: a PCB board 1; a response contact 2 disposed on the PCB board 1; a button assembly 3 disposed towards the response contact 2, the button assembly 3 being movable relative to the response contact 2, the button assembly 3 having at least a first position and a second position when moving relative to the response contact 2, the button assembly 3 applying a force F1 to the response contact 2 or separating from the response contact 2 when the button assembly 3 is in the first position, the button assembly 3 applying a force F2 to the response contact 2 when the button assembly 3 is in the second position, the button assembly 3 applying a force F2 to the response contact 2, the F2 being greater than the F1; and a protective cover 4 disposed on the response contact 2 and / or the button assembly 3, the protective cover 4 being located between the response contact 2 and the button assembly 3.

[0042] The first aspect of this application discloses a silent button structure. Through the arrangement of the PCB board 1 and the response contact 2, the movement of the button assembly 3 can control the power on / off and speed adjustment functions of a product equipped with this silent button structure. For example, when the button assembly 3 is in the first position, it controls the power off of the product; when the button assembly 3 is in the second position, it controls the power on of the product. A protective cover 4 is disposed on the response contact 2, located between the response contact 2 and the button assembly 3. The protective cover 4 is made of a soft material, essentially acting as a protective sleeve on the response contact 2, thereby reducing the hard feel when the button assembly 3 and the response contact 2 make contact, resulting in a better user experience. This design effectively reduces the noise generated when the button assembly 3 and the response contact 2 make contact. Furthermore, the dimensional tolerance between the PCB board 1 and the response contact 2 can be positive. This positive tolerance can be offset by the slight deformation of the protective cover 4, ensuring a tight contact between the button assembly 3, the protective cover 4, and the response contact 2. The button assembly 3 will not jam and fail, allowing for greater design flexibility and a more compact overall structure. This product can be widely used in household appliances such as televisions, air conditioners, refrigerators, audio equipment, and hair dryers, and has a wide range of applications.

[0043] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the protective cover 4 is sleeved on the response contact 2. By sleeved on the response contact 2, when the button assembly 3 is pressed, the button assembly 3 first contacts the protective cover 4. Since the protective cover 4 is made of a soft material, it can effectively buffer the pressure applied by the button assembly 3, thereby reducing the harshness between the button assembly 3 and the response contact 2. This design makes the user feel a smoother and softer sensation when operating the button, greatly improving the comfort of operation.

[0044] In addition to the features of the above embodiments, this embodiment further specifies that the protective cover 4 is sleeved on the button assembly 3. By sleeved on the button assembly 3, the harshness when the button assembly 3 contacts the response contact 2 can be effectively reduced, providing a softer tactile feel. This design is particularly suitable for prolonged use, reducing hand discomfort and fatigue.

[0045] like Figure 1-3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the button assembly 3 and the response contact 2 are arranged opposite to each other. By arranging the button assembly 3 and the response contact 2 opposite to each other, the user can directly and accurately trigger the response contact 2 when pressing the button assembly 3. This design simplifies the operation process and improves the convenience and efficiency of operation.

[0046] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines: the button assembly 3 includes a pressure post 31, a pressing part 32, and a limiting member 33. The pressure post 31 is disposed opposite to the response contact 2. When the button assembly 3 is in the first position, the pressure post 31 applies the force F1 to the response contact 2. When the button assembly 3 is in the second position, the pressure post 31 applies the force F2 to the response contact 2. The pressing part 32 is disposed on the pressure post 31, and the limiting member 33 is disposed on the pressing part 32. The limiting member 33 and the pressure post 31 are located on the same side of the pressing part 32. The pressure post 31 ensures good contact with the response contact 2, resulting in a fast response speed. The limiting member 33 restricts the movement range of the button assembly when the product is installed on an electronic device, preventing the product from detaching from the electronic device. This design improves the durability and reliability of the product.

[0047] In addition to the features of the above embodiments, this embodiment further specifies that the protective cover 4 is sleeved on the pressure post 31. By sleeved on the pressure post 31, the sound emitted when the pressure post 31 contacts the response contact 2 can be reduced. Furthermore, it can effectively reduce wear when the pressure post 31 is in direct contact with the response contact 2. This protective effect helps to extend the service life of the pressure post 31 and improve the overall reliability of the product.

[0048] like Figure 1-4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the length of the pressure post 31 is greater than or equal to the length of the limiting member 33. By making the length of the pressure post 31 greater than or equal to the length of the limiting member 33, the design is more reasonable. While ensuring effective contact and separation between the button assembly 3 and the response contact 2, it also ensures a shorter moving distance for the button assembly 3, limiting the moving range of the button assembly 3, thereby making operation simpler.

[0049] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the limiting member 33 includes a limiting plate 331 and a protruding buckle 332. The limiting plate 331 is disposed on the pressing part 32, and the protruding buckle 332 is disposed on the limiting plate 331 and located at the end of the limiting plate 331 away from the pressing part 32. The protruding buckle 332 is used to abut against an external device. By disposing of the protruding buckle 332 on the limiting plate 331, the limiting plate 331 provides stable support for the protruding buckle 332. The protruding buckle 332 limits the movement range of the button assembly 3, preventing the button assembly 3 from detaching from the device, thereby improving the usability of the button assembly 3.

[0050] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of limiting members 33 is multiple, all of the multiple limiting members 33 are disposed on the pressing part 32 and are all located on the same side of the pressing part 32, and each of the multiple limiting members 33 has a protruding buckle 332 formed thereon, and the orientation of the multiple protruding buckles 332 is different. The arrangement of multiple limiting members 33 can better prevent the button assembly 3 from detaching from the device, improving the durability and reliability of the product. Because the multiple protruding buckles 332 are oriented differently, each of the multiple protruding buckles 332 can abut against an external device to limit the range of movement of the button assembly 3, preventing the button assembly 3 from detaching from the device. Furthermore, it can reduce the wear of individual protruding buckles 332. This design helps to extend the overall service life of the button assembly 3.

[0051] In addition to the features of the above embodiments, this embodiment further specifies that the Shore hardness value of the protective cover 4 is 65-70 degrees. This Shore hardness range of 65-70 degrees provides the protective cover 4 with moderate softness. When the user presses the button assembly 3, the protective cover 4 can produce a certain degree of elastic deformation, avoiding an overly stiff feeling. Compared to protective covers with excessive hardness, it provides a softer touch, reduces the impact of pressing force on the user's fingers, and makes operation more comfortable, especially suitable for scenarios involving prolonged use of button devices.

[0052] In addition to the features of the above embodiments, this embodiment further specifies that the thickness of the protective cover 4 is 1-2 mm. By limiting the thickness of the protective cover 4 to 1-2 mm, this thickness range prevents it from being excessively bulky, allowing for rapid transmission of pressure to the response contact 2 when the user presses the button assembly 3, reducing pressing delay and making the operation more sensitive. Furthermore, it avoids providing excessive resistance to the user's fingers, making the pressing operation smoother.

[0053] In addition to the features of the above embodiments, this embodiment further specifies that the protective cover 4 is made of silicone material. Because the protective cover 4 is made of silicone material, it possesses excellent softness and elasticity. When the user presses the button, the protective cover 4 can elastically deform, providing an extremely comfortable tactile experience for the fingers and greatly improving the user's operational comfort.

[0054] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the response contact 2 includes a first contact head 21 and a second contact head 22, the first contact head 21 is disposed on the PCB board 1, the second contact head 22 is disposed on the first contact head 21, the button assembly 3 can apply the force F1 and the force F2 to the second contact head 22, and the protective cover 4 is sleeved on the second contact head 22. The distribution of the first contact head 21 and the second contact head 22 allows the protective cover 4 to be better sleeved on the second contact head 22 while preventing the protective cover 4 from contacting the PCB board 1 and affecting its performance.

[0055] Example 2

[0056] like Figure 6-8 As shown, this embodiment discloses an electronic device, including: a housing assembly 100, the housing assembly 100 having a through hole 1001; an electrical structure, the electrical structure being disposed on the housing assembly 100 and located inside the housing assembly 100; and the aforementioned silent button structure 200, the PCB board 1 being disposed on the electrical structure, the button assembly 3 being disposed on the housing assembly 100 and located at the through hole 1001, the button assembly 3 being movable relative to the housing assembly 100, the button assembly 3 having at least a first position and a second position when moving relative to the housing assembly 100, the electrical structure being in a first state when the button assembly 3 is in the first position, and the electrical structure being in a second state when the button assembly 3 is in the second position.

[0057] The second aspect of this application discloses an electronic device in which a button assembly 3 corresponds to different working states of the electrical structure at different positions. Users can easily switch between different functional states according to their needs, such as switching from the device's standby state (first state) to its working state (second state), making operation simple and intuitive. This precise control helps ensure the effective execution of the device's functions and avoids functional malfunctions caused by inaccurate button operation. The silent button structure 200 is located at the through-hole 1001. The compact design of the silent button structure 200 prevents the buttons from appearing obtrusive, helping the electronic device maintain a simple and aesthetically pleasing design, meeting the high demands of modern consumers for the appearance of electronic devices.

[0058] like Figure 7 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a protrusion 332 is formed on the button assembly 3, the protrusion 332 is located inside the housing assembly 100, and the protrusion 332 can abut against or separate from the housing assembly 100. By abutting against the housing assembly 100 with the protrusion 332, the movement of the button assembly 3 reaches its maximum stroke, which can limit the degree of freedom of the button assembly 3, thereby preventing the button assembly 3 from detaching from the electronic device and improving the durability of the product.

[0059] like Figure 6 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: when the button assembly 3 is in the first position, the protruding buckle 332 abuts against the housing assembly 100; when the button assembly 3 is in the second position, the protruding buckle 332 separates from the housing assembly 100. By abutting or separating the protruding buckle 332 from the housing assembly 100, the button assembly 3 is able to control the functions of the electronic device while preventing the button assembly 3 from detaching from the housing assembly 100.

[0060] like Figure 6-8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of protrusions 332 is two, both of which can abut or separate from the housing assembly 100, and the two protrusions 332 face opposite directions. By having the two protrusions 332 face opposite directions, local stress concentration that may be caused by excessive force on a single protrusion 332 is avoided, thereby reducing the risk of damage to the button assembly 3 itself and further improving the reliability of the entire button structure.

[0061] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
