Description

Technical Field

[0001] This invention relates to the field of button technology, and more particularly to a button assembly and an electronic device. Background Technology

[0002] For buttons with two different pressing ends (such as the volume buttons on a mobile phone, where the two opposite ends are the pressing ends for adjusting the volume up and down), there is often a problem of how to avoid accidental touches caused by the two pressing ends working together.

[0003] The mobile phone side button device and mobile phone disclosed in the related technology with publication number CN102594953B adopt a support component to support the key skirt located between the two conductive bases (equivalent to two pressing ends) of the side button, so that the side button is formed into a seesaw-like structure with both ends rotatable around the key skirt as the center, so as to achieve the effect of avoiding the linkage between the two pressing ends of the side button.

[0004] However, under this design, when the phone is bumped and the impact force is applied to the side button, the impact force on the side button can only be transmitted to the support component, resulting in excessive pressure on the support component, which is prone to breakage, and the structural reliability of the side button is poor. Summary of the Invention

[0005] This invention discloses a button assembly and an electronic device. The button assembly can prevent linkage between two opposite ends, and the button assembly has good structural reliability.

[0006] To achieve the above objectives, in a first aspect, the present invention discloses a button assembly, comprising:

[0007] The button body includes a first end and a second end opposite to each other; and

[0008] An anti-interlocking mechanism, comprising a first pressure limiting tube, a first sliding plug, a second pressure limiting tube, and a second sliding plug;

[0009] The first pressure limiting tube is disposed corresponding to the first end. The first pressure limiting tube has a first pressure limiting cavity and a first opening facing the first end and communicating with the first pressure limiting cavity. The first pressure limiting cavity is used to fill fluid. The first sliding plug is located in the first pressure limiting cavity and is slidably sealed to the inner wall of the cavity of the first pressure limiting tube. The first sliding plug is used to slide in a direction away from the first opening when pressed by the first end to squeeze the fluid filled in the first pressure limiting cavity.

[0010] The second pressure limiting tube is provided corresponding to the second end. The second pressure limiting tube has a second pressure limiting cavity and a second opening facing the second end and communicating with the second pressure limiting cavity. The second pressure limiting cavity is used to fill fluid. The second sliding plug is located in the second pressure limiting cavity and is slidably sealed to the inner wall of the cavity of the second pressure limiting tube. The second sliding plug is used to slide in a direction away from the second opening when pressed by the second end to squeeze the fluid filled in the second pressure limiting cavity.

[0011] The second pressure limiting chamber is connected to the first pressure limiting chamber so that the fluid can flow between the first pressure limiting chamber and the second pressure limiting chamber.

[0012] As an optional implementation, in an embodiment of the first aspect of the present invention, the first pressure limiting tube includes a first pipe section and a second pipe section connected in communication. The first pipe section is provided with the first opening. The first plug is slidably and sealingly connected to the inner wall of the first pipe section. The second pipe section is connected to the end of the first pipe section opposite to the first opening. At least a portion of the inner diameter of the second pipe section is smaller than the inner diameter of the first pipe section.

[0013] The second pressure limiting tube includes a third pipe section and a fourth pipe section that are connected to each other. The third pipe section is provided with the second opening. The second sliding plug is slidably and sealingly connected to the inner wall of the third pipe section. The fourth pipe section is connected to the end of the third pipe section that is away from the second opening. At least part of the inner diameter of the fourth pipe section is smaller than the inner diameter of the third pipe section. The fourth pipe section is connected to the second pipe section.

[0014] As an optional implementation, in an embodiment of the first aspect of the present invention, the anti-interlocking mechanism further includes a connecting pipe, one end of which is connected to the end of the first pressure limiting pipe opposite to the first opening, and the other end of which is connected to the end of the second pressure limiting pipe opposite to the second opening. The connecting pipe is used to allow the fluid to flow between the first pressure limiting chamber, the connecting pipe, and between the connecting pipe and the second pressure limiting chamber.

[0015] As an optional implementation, in an embodiment of the first aspect of the present invention, the anti-interlocking mechanism further includes a pressure relief component, which includes a third pressure limiting pipe and a pressure limiting plug;

[0016] The third pressure limiting tube is disposed between the first end and the second end, the third pressure limiting tube has a third pressure limiting cavity, and the third pressure limiting tube is connected to the connecting tube to allow fluid to flow between the third pressure limiting cavity and the connecting tube;

[0017] The pressure limiting plug is slidably sealed to the inner wall of the third pressure limiting chamber along the sliding direction. The pressure limiting plug is used to slide along the sliding direction when the total force it receives along the sliding direction is greater than a first threshold, so that the fluid in the connecting pipe can enter the third pressure limiting chamber, thereby moving the first end and the second end from the initial position to the contracted position, or squeezing the fluid from the third pressure limiting chamber into the connecting pipe, thereby returning the first end and the second end from the contracted position to the initial position.

[0018] The initial position is the position when the first end and the second end are not subjected to additional pressing force, and the contraction position is the position when the first end and the second end are subjected to impact force simultaneously.

[0019] As an optional implementation, in an embodiment of the first aspect of the present invention, one end of the third pressure limiting tube is connected to the connecting tube, and the other end of the third pressure limiting tube is provided with a third opening connected to the third pressure limiting cavity;

[0020] The pressure relief assembly further includes an elastic element disposed within the third pressure limiting chamber. One end of the elastic element is connected to the third pressure limiting chamber, and the other end of the elastic element is connected to the pressure limiting plug. The elastic element is used to apply an elastic force along the sliding direction to the pressure limiting plug.

[0021] As an optional implementation, in an embodiment of the first aspect of the present invention, the first threshold is F0, when the first end and the second end are located at the initial position, the elastic force applied by the elastic element to the pressure limiting plug is F1, the minimum value of the impact force simultaneously received by the first end and the second end is F2, and the distance from the contraction position to the initial position is x.

[0022] When the maximum outer diameters of the first and second sliding plugs are equal, and the maximum outer diameter of the pressure-limiting plug is also equal, and both the first and second sliding plugs are designed to slide when the applied force exceeds a second threshold F3, the fluid is a liquid, and the maximum pressing force applied simultaneously by the user to the first and second ends is F4, the stiffness coefficient k of the elastic element satisfies the following:

[0023]

[0024] The units for F0, F1, F2, F3, and F4 are all N.

[0025] As an optional implementation, in an embodiment of the first aspect of the present invention, a first transmission member is movably inserted through the first opening, one end of the first transmission member points to the first slide plug, the other end of the first transmission member points to the first end, and the first end and the first slide plug are pressed against each other through the first transmission member; a second transmission member is movably inserted through the second opening, one end of the second transmission member points to the second slide plug, the other end of the second transmission member points to the second end, and the second end and the second slide plug are pressed against each other through the second transmission member.

[0026] As an optional implementation, in an embodiment of the first aspect of the present invention, the button body includes a pressing part, a first elastic connecting part, and a second elastic connecting part. The pressing part has a first end and a second end. One end of the first elastic connecting part is connected to the first end, and the other end of the first elastic connecting part is used to connect to an external structure. One end of the second elastic connecting part is connected to the second end, and the other end of the second elastic connecting part is used to connect to the external structure. Both the first pressure limiting tube and the second pressure limiting tube are used to connect to the external structure.

[0027] In a second aspect, the present invention discloses a device body and a button assembly as described in the first aspect above, wherein the button assembly is disposed on the device body.

[0028] As an optional implementation, in an embodiment of the second aspect of the present invention, the device body is provided with a button hole, the button body of the button assembly is movably disposed through the button hole, and the button body part is located inside the device body to be connected to the device body, the anti-interlocking mechanism is located inside the device body, and the first pressure limiting tube and the second pressure limiting tube are fixedly connected to the device body.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] The button assembly and electronic device provided in this invention achieve an anti-linkage effect between the first and second ends of the button body through an anti-linkage mechanism. Specifically, utilizing the elastic properties of the fluid within the first and second pressure-limiting tubes included in the anti-linkage mechanism, when the first slider is pressed and slides towards the first pressure-limiting tube, the second slider will slide away from the second pressure-limiting tube under the elastic action of the fluid. Conversely, when the second slider is pressed and slides towards the second pressure-limiting tube, the first slider will slide away from the first pressure-limiting tube under the elastic action of the fluid, thereby achieving the function of preventing linkage between the first and second ends corresponding to the first and second sliders, respectively.

[0031] Furthermore, when the button body is subjected to an impact, the first end will transfer the force to the first slider, and the second end will transfer the force to the second slider. In other words, the impact force can be distributed to the first slider and the second slider, so that the pressure generated by the impact force on the first slider and the second slider is smaller, and the first slider and the second slider are not easy to break. The overall structural reliability of the button assembly is better. Attached Figure Description

[0049] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0050] Please refer to the following: Figures 1 to 3 , Figure 1 This is a simplified cross-sectional view of the button assembly (button body in the initial position) disclosed in the first aspect of the embodiments of this application. Figure 2 This is a simplified cross-sectional view of the button assembly (with the first end of the button body being pressed) disclosed in the first aspect of the embodiments of this application. Figure 3 This is a three-dimensional structural schematic diagram of the button assembly disclosed in the first aspect of the present application. The first aspect of the present invention discloses a button assembly 1, which can be applied to, but is not limited to, electronic devices such as mobile phones, tablets, portable music players, or headphones, as at least one button included in the electronic device, realizing the button function with two pressing ends. For example, the button assembly 1 can be used as a volume adjustment button included in the electronic device, and the two pressing ends respectively realize the button function of increasing or decreasing the volume.

[0051] Specifically, the button assembly 1 includes a button body 10 and an anti-linkage mechanism 11. The button body 10 includes a first end 10a and a second end 10b, which are opposite to each other. The first end 10a and the second end 10b are the two pressing ends of the button body 10. The anti-linkage mechanism 11 includes a first pressure limiting tube 110, a first sliding plug 111, a second pressure limiting tube 112, and a second sliding plug 113. The first pressure limiting tube 110 is disposed corresponding to the first end 10a. The first pressure limiting tube 110 has a first pressure limiting cavity 110a and a first opening 110b that faces the first end 10a and communicates with the first pressure limiting cavity 110a. The first pressure limiting cavity 110a is used to fill fluid 12. The first sliding plug 111 is located in the first pressure limiting cavity 110a and is slidably sealed to the inner wall of the cavity of the first pressure limiting tube 110. The first sliding plug 111 is used to move away from the first opening 110b when pressed by the first end 10a. A sliding tube 112 is provided corresponding to the second end 10b, and has a second pressure-limiting cavity 112a and a second opening 112b that faces the second end 10b and communicates with the second pressure-limiting cavity 112a. The second pressure-limiting cavity 112a is used to fill the fluid 12. A second sliding plug 113 is located in the second pressure-limiting cavity 112a and is slidably sealed to the inner wall of the cavity of the second pressure-limiting tube 112. The second sliding plug 113 is used to slide away from the second opening 112b when pressed by the second end 10b to squeeze the fluid 12 filled in the second pressure-limiting cavity 112a. The second pressure-limiting cavity 112a communicates with the first pressure-limiting cavity 110a to allow the fluid 12 to flow between the first pressure-limiting cavity 110a and the second pressure-limiting cavity 112a. Figure 1 As shown, Figure 1 The structure of the button assembly 1 is shown when the button body 10 is not subjected to additional pressing force.

[0052] like Figure 2 As shown, when the first end 10a is pressed, the first end 10a is used to drive the first slide plug 111 to slide in a direction away from the first opening 110b. The fluid 12 in the first pressure limiting chamber 110a is pressed by the first slide plug 111 to partially flow into the second pressure limiting chamber 112a, so that the second slide plug 113 slides in a direction close to the second opening 112b, thereby driving the second end 10b to move in a direction away from the anti-linkage mechanism 11, so as to avoid the second end 10b being affected by the linkage.

[0053] When the second end 10b is pressed, the second end 10b is used to drive the second slide plug 113 to slide in a direction away from the second opening 112b. The fluid 12 in the second pressure limiting chamber 112a is pressed by the second slide plug 113 to partially flow to the first pressure limiting chamber 110a, so that the first slide plug 111 slides in a direction close to the first opening 110b, thereby driving the first end 10a to move in a direction away from the anti-linkage mechanism 11, so as to avoid the first end 10a being affected by the linkage.

[0054] Furthermore, when the button body 10 is subjected to an impact, the first end 10a transmits the force to the first slider 111, and the second end 10b transmits the force to the second slider 113. In other words, compared to the structure of the side button in the related art mentioned in the background art, which can only transmit the impact force to the support component when subjected to an impact, the button body 10 provided in this application can disperse the impact force to the first slider 111 and the second slider 113, thereby making the pressure generated by the impact force on the first slider 111 and the second slider 113 smaller, and the first slider 111 and the second slider 113 less prone to breakage. The overall structural reliability of the button assembly 1 is better.

[0055] Please refer to the following: Figure 1 , Figure 4 and Figure 5 In some embodiments, the diameter d1 of the first opening 110b may be smaller than the maximum outer diameter r1 of the first sliding plug 111, thereby preventing the first sliding plug 111 from sliding out of the first pressure limiting cavity 110a from the first opening 110b, causing the fluid 12 filled in the first pressure limiting cavity 110a to leak, and the structure of the anti-linkage mechanism 11 changes, losing its anti-linkage function.

[0056] Optionally, a first transmission member 111a, which is rod-shaped, tubular, or otherwise shaped, is movably inserted through the first opening 110b. One end of the first transmission member 111a points to the first slide plug 111, and the other end of the first transmission member 111a points to the first end 10a, so that the first end 10a and the first slide plug 111 are pressed against each other through the first transmission member 111a.

[0057] It should be noted that the phrase "one of the two points to the other" as mentioned above includes, but is not limited to, one of the two being spaced apart from the other, one of the two being abutted against the other, one of the two being fixedly connected to the other, and one of the two being movably connected to the other. Furthermore, if the relative positions of the two change, causing them to move from being spaced apart to abutting against each other, or from abutting against each other to being spaced apart, it can be considered that the two are always in a state of "one of the two pointing to the other."

[0058] In one alternative example, the first transmission member 111a may be fixedly connected to the first slide 111 at one end, and the other end may be non-fixedly connected to the first end 10a, so that the connection between the first transmission member 111a and the first slide 111 forms a more stable structure, thereby making the transmission function of the first transmission member 111a more stable.

[0059] Optionally, the first transmission component 111a can be integrally formed with the first slide plug 111 to simplify the preparation and assembly process of the first slide plug 111 and the first transmission component 111a, and to make the connection between the first transmission component 111a and the first slide plug 111 more stable.

[0060] In another alternative example, the first transmission member 111a may be non-fixedly connected at one end to the first slide 111, and the other end may be fixedly connected to the first end 10a, so that the connection between the first transmission member 111a and the first end 10a forms a more stable structure, thereby making the transmission function of the first transmission member 111a more stable.

[0061] Optionally, the first transmission component 111a can be integrally formed with the first end 10a to simplify the preparation and assembly process of the first end 10a and the first transmission component 111a, and to make the connection between the first transmission component 111a and the first end 10a more stable.

[0062] In another alternative example, the first transmission member 111a may be movably connected at one end to the first slide 111 and at the other end to the first end 10a, so that the relative positions of the first transmission member 111a with the first end 10a and the first slide 111 are relatively stable, thereby making the transmission function of the first transmission member 111a more stable.

[0063] Optionally, the first pressure-limiting tube 110 may include a first pipe section 110c and a second pipe section 110d connected in communication. The first pipe section 110c has a first opening 110b, and a first sliding plug 111 is slidably and sealingly connected to the inner wall of the first pipe section 110c. The second pipe section 110d is connected to the end of the first pipe section 110c away from the first opening 110b. At least part of the inner diameter of the second pipe section 110d is smaller than the inner diameter of the first pipe section 110c. By setting the first pressure-limiting tube 110 as a segmented structure, it is convenient to install the first sliding plug 111 from the end of the first pipe section 110c away from the first opening 110b into the first pipe section 110c, and it is also convenient to allow the fluid 12 to pass through the second pipe section 110d. The end of segment 110d used to connect to the first pipe segment 110c is filled into the second pipe segment 110d. In other words, after the second pipe segment 110d is connected to the second pressure limiting pipe 112, fluid 12 is filled into the second pipe segment 110d, the first sliding plug 111 is installed into the first pipe segment 110c, and then the first pipe segment 110c and the second pipe segment 110d are connected by threaded connection, welding or adhesive bonding, etc., without having to connect the first pressure limiting pipe 110 to the second pressure limiting pipe 112 after the first sliding plug 111 is installed and filled with fluid 12. In the process of connecting the first pressure limiting pipe 110 and the second pressure limiting pipe 112, the filled fluid 12 is easy to overflow, and the connection process is difficult.

[0064] Furthermore, since the inner diameter of at least part of the second pipe section 110d is smaller than the inner diameter of the first pipe section 110c, the first sliding plug 111 can be confined within the first pressure limiting pipe 110 through the second pipe section 110d, and will not be disengaged from the first pressure limiting pipe 110 through the second pipe section 110d, so that the structure and function of the anti-linkage mechanism 11 are both relatively stable.

[0065] Optionally, a first connecting part 110e may be provided on the outer periphery of the first pipe segment 110c. The first connecting part 110e is used to fix and connect to an external structure (such as the device body of an electronic device) by means of adhesive, snap-fit, etc., so that the first pipe segment 110c is fixedly connected to the external structure, so that the connection between the first pressure limiting pipe 110 and the external structure is more stable. Therefore, when the first sliding plug 111 slides in the first pressure limiting pipe 110, the relative position between the first pressure limiting pipe 110 and the external structure is less affected, so the structural stability of the anti-linkage mechanism 11 is better.

[0066] In some embodiments, the diameter d2 of the second opening 112b may be smaller than the maximum outer diameter r2 of the second slide plug 113, thereby preventing the second slide plug 113 from sliding out of the second pressure limiting chamber 112a from the second opening 112b, causing the fluid 12 filled in the second pressure limiting chamber 112a to leak, and the structure of the anti-linkage mechanism 11 to change, losing its anti-linkage function.

[0067] Optionally, a rod-shaped, tubular, or other shaped second transmission member 113a is movably inserted through the second opening 112b. One end of the second transmission member 113a points to the second slide plug 113, and the other end of the second transmission member 113a points to the second end 10b, so that the second end 10b and the second slide plug 113 are pressed against each other through the second transmission member 113a.

[0068] It should be noted that the phrase "one of the two points to the other" mentioned above includes, but is not limited to, one of the two being spaced apart from the other, one of the two being abutted against the other, one of the two being fixedly connected to the other, and one of the two being movably connected to the other. Furthermore, if the relative positions of the two change, causing them to change from being spaced apart to abutting against each other, or from abutting against each other to being spaced apart, it can be considered that the two are always in a state of "one of the two points to the other".

[0069] In one alternative example, the second transmission member 113a may be fixedly connected to the second slide 113 at one end, and the other end may be non-fixedly connected to the second end 10b, so that the connection between the second transmission member 113a and the second slide 113 forms a more stable structure, thereby making the transmission function of the second transmission member 113a more stable.

[0070] Optionally, the second transmission component 113a can be integrally formed with the second slide plug 113 to simplify the preparation and assembly process of the second slide plug 113 and the second transmission component 113a, and to make the connection between the second transmission component 113a and the second slide plug 113 more stable.

[0071] In another alternative example, the second transmission member 113a may be non-fixedly connected at one end to the second slide 113, and the other end may be fixedly connected to the second end 10b, so that the connection between the second transmission member 113a and the second end 10b forms a more stable structure, thereby making the transmission function of the second transmission member 113a more stable.

[0072] Optionally, the second transmission component 113a can be integrally formed with the second end 10b to simplify the preparation and assembly process of the second end 10b and the second transmission component 113a, and to make the connection between the second transmission component 113a and the second end 10b more stable.

[0073] In another alternative example, the second transmission member 113a may be movably connected at one end to the second slide 113 and at the other end to the second end 10b, so that the relative positions of the second transmission member 113a with the second end 10b and the second slide 113 are relatively stable, thereby making the transmission function of the second transmission member 113a more stable.

[0074] Optionally, the second pressure-limiting tube 112 may include a third tube segment 112c and a fourth tube segment 112d that are connected in series. The third tube segment 112c has a second opening 112b, and the second sliding plug 113 is slidably and sealingly connected to the inner wall of the third tube segment 112c. The fourth tube segment 112d is connected to the end of the third tube segment 112c that is away from the second opening 112b. At least part of the inner diameter of the fourth tube segment 112d is smaller than the inner diameter of the third tube segment 112c. The fourth tube segment 112d is connected to the second tube segment 110d. By setting the second pressure-limiting tube 112 as a segmented structure, it is convenient to install the second sliding plug 113 from the end of the third tube segment 112c away from the second opening 112b into the third tube segment 112c. On the other hand, it is convenient to... Fluid 12 is filled into the fourth pipe section 112d through the end of the fourth pipe section 112d that is connected to the third pipe section 112c. In other words, after the fourth pipe section 112d is connected to the second pipe section 110d, fluid 12 is filled into the fourth pipe section 112d, and the second sliding plug 113 is installed into the third pipe section 112c. Then, the third pipe section 112c and the fourth pipe section 112d are connected by threaded connection, welding or adhesive bonding, etc., without having to connect the second pressure limiting pipe 112 to the first pressure limiting pipe 110 after the second sliding plug 113 is installed and filled with fluid 12. During the connection process between the second pressure limiting pipe 112 and the first pressure limiting pipe 110, the filled fluid 12 is prone to overflow, and the connection process is difficult.

[0075] Furthermore, since the inner diameter of at least part of the fourth pipe section 112d is smaller than the inner diameter of the third pipe section 112c, the second sliding plug 113 can be confined within the second pressure limiting pipe 112 through the fourth pipe section 112d, and will not be disengaged from the second pressure limiting pipe 112 through the fourth pipe section 112d, so that the structure and function of the anti-linkage mechanism 11 are both relatively stable.

[0076] Optionally, a second connecting part 112e may be provided on the outer periphery of the second pipe segment 112c. The second connecting part 112e is used to fix and connect to an external structure (such as the device body of an electronic device) by means of adhesive, snap-fit, etc., so that the second pipe segment 112c is fixedly connected to the external structure, so that the connection between the second pressure limiting pipe 112 as a whole and the external structure is more stable. Therefore, when the second sliding plug 113 slides in the second pressure limiting pipe 112, the relative position between the second pressure limiting pipe 112 as a whole and the external structure is less affected, so the structural stability of the anti-linkage mechanism 11 is better.

[0077] In some embodiments, the anti-interlocking mechanism 11 may further include a connecting pipe 114. One end of the connecting pipe 114 is connected to the end of the first pressure limiting pipe 110 away from the first opening 110b, and the other end of the connecting pipe 114 is connected to the end of the second pressure limiting pipe 112 away from the second opening 112b. The connecting pipe 114 is used to supply fluid 12 to flow between the first pressure limiting chamber 110a, the connecting pipe 114, and the connecting pipe 114 and the second pressure limiting chamber 112a. Thus, by setting the connecting pipe 114, the first pressure limiting chamber 110a and the second pressure limiting chamber 112a can be indirectly connected on the one hand, and the first pressure limiting pipe 110 and the second pressure limiting pipe 112 can be separated on the other hand, making it easier for the first pressure limiting pipe 110 and the second pressure limiting pipe 112 to be respectively set to the first end 10a and the second end 10b.

[0078] Since the electronic device to which the button assembly 1 is used typically also includes other electronic components compactly arranged with the button assembly 1, the connecting pipe 114 may optionally include at least one bent section 114a to avoid obstruction by other electronic components, such as... Figure 4 As shown, Figure 4 The diagram shows that the two opposite ends of the connecting pipe 114 each include two bent sections 114a.

[0079] Considering that when the button body 10 is subjected to excessive impact force, even if the impact force is distributed and transmitted to the first slider 111 and the second slider 113 respectively through the first transmission member 111a and the second transmission member 113a, it may still cause at least one of the first transmission member 111a, the first slider 111, the second transmission member 113a, and the second slider 113 to break, resulting in the anti-linkage mechanism 11 losing its anti-linkage function. Please refer to the following: Figure 1 , Figure 4 and Figure 6 Based on this, in some embodiments, the anti-interlocking mechanism 11 may further include a pressure relief component 115. This pressure relief component 115 is used to release at least a portion of the fluid 12 filled in the first pressure-limiting chamber 110a and the second pressure-limiting chamber 112a when the impact force on the button body 10 is too large. This allows the first end 10a and the second end 10b to move as a whole from the initial position to the retracted position, thereby retracting into the interior of the electronic device body. This allows the device body to bear the excessive impact force instead of the button body 10, protecting the structure of the button assembly 1. The initial position is the position where the first end 10a and the second end 10b are not subjected to additional pressing force, and the retracted position is the position where the first end 10a and the second end 10b are simultaneously subjected to a large impact force. Figure 1 As shown, Figure 1 The diagram shows the overall structure of the button assembly 1 when the first end 10a and the second end 10b are in their initial positions, as shown below. Figure 6 As shown, Figure 6The diagram shows the overall structure of the button assembly 1 when the first end 10a and the second end 10b are in the retracted position. Figure 6 The dashed line in the middle shows the position of the first end 10a and the second end 10b when they are in the initial position.

[0080] Optionally, the pressure relief assembly 115 may include a third pressure limiting tube 1150 and a pressure limiting plug 115a. The third pressure limiting tube 1150 may have a third pressure limiting cavity 1150a. The third pressure limiting tube 1150 is connected to the connecting tube 114 to allow fluid 12 to flow between the third pressure limiting cavity 1150a and the connecting tube 114. The pressure limiting plug 115a is slidably sealed to the inner wall of the third pressure limiting cavity 1150a along the sliding direction S. The pressure limiting plug 115a is used to slide along the sliding direction S when the total force it receives along the sliding direction S is greater than a first threshold, so that the fluid 12 in the connecting tube 114 enters the third pressure limiting cavity 1150a, so that the first end 10a and the second end 10b move from the initial position to the contracted position, or squeeze the fluid 12 from the third pressure limiting cavity 1150a into the connecting tube 114, so that the first end 10a and the second end 10b return from the contracted position to the initial position.

[0081] Wherein, the sliding direction S is the relative direction between the pressure limiting plug 115a and the fluid 12 in contact with the pressure limiting plug 115a. The sliding direction S includes a first sub-sliding direction S1 and a second sub-sliding direction S2, which are opposite to each other. The first sub-sliding direction S1 is the direction from the fluid 12 in contact with the pressure limiting plug 115a towards the pressure limiting plug 115a, and the second sub-sliding direction S2 is the direction from the pressure limiting plug 115a towards the fluid 12 in contact with the pressure limiting plug 115a. Figure 1 and Figure 6 As shown, Figure 1 and Figure 6 The arrows in the diagram indicate the sliding direction S, the first sub-sliding direction S1, and the second sub-sliding direction S2.

[0082] Therefore, when the button body 10 is subjected to a large impact force, the first end 10a and the second end 10b transmit the impact force to the first slider 111 and the second slider 113 respectively through the first transmission member 111a and the second transmission member 113a. The first slider 111 and the second slider 113 simultaneously compress the fluid 12, so that the impact force is concentrated and transmitted to the pressure limiting plug 115a through the fluid 12. Since the impact force is large at this time, the total force on the pressure limiting plug 115a along the first sub-sliding direction S1 is greater than the first threshold. Therefore, the pressure limiting plug 115a slides along the first sub-sliding direction S1 under the compression of the fluid 12, so as to allow the connecting pipe 114 to slide. The fluid 12 inside enters the third pressure limiting chamber 1150a, so that some of the fluid 12 in the first pressure limiting chamber 110a and the second pressure limiting chamber 112a can flow into the connecting pipe 114 under the compression of the first sliding plug 111 and the second sliding plug 113 respectively. The first sliding plug 111 slides in the direction toward the first pressure limiting chamber 110a, and the second sliding plug 113 slides in the direction toward the second pressure limiting chamber 112a. Finally, the first end 10a and the second end 10b move from the initial position to the contracted position, thereby retracting into the device body of the electronic device in which the button assembly 1 is applied, so as to withstand the impact force through the device body and extend the service life of the button assembly 1.

[0083] Optionally, the third pressure limiting tube 1150 may be disposed between the first end 10a and the second end 10b, thereby making the structure of the anti-interlocking mechanism 11 more compact.

[0084] Furthermore, one end of the third pressure limiting tube 1150 can also be positioned between the first end 10a and the second end 10b to further improve the structural compactness of the anti-interlocking mechanism 11.

[0085] It is understood that as long as the third pressure limiting tube 1150 is directly or indirectly connected to the first pressure limiting cavity 110a and the second pressure limiting cavity 112a respectively, the pressure relief component 115 can release at least part of the fluid 12 filled in the first pressure limiting cavity 110a and the second pressure limiting cavity 112a when the impact force on the button body 10 is too large, so as to allow the first end 10a and the second end 10b to move from the initial position to the contracted position as a whole. Therefore, in other embodiments, the third pressure limiting tube 1150 can also be connected to the first pressure limiting tube 110 to directly connect to the first pressure limiting cavity 110a and indirectly connect to the second pressure limiting cavity 112a, or the third pressure limiting tube 1150 can also be connected to the second pressure limiting tube 112 to directly connect to the second pressure limiting cavity 112a and indirectly connect to the first pressure limiting cavity 110a. Furthermore, as long as there is sufficient space, the end of the third pressure limiting tube 1150 can be oriented in any direction. The orientation of the end of the third pressure limiting tube 1150 can be designed according to the actual situation, and this embodiment does not impose specific limitations.

[0086] Optionally, the third pressure-limiting tube 1150 may include a fifth tube segment 1150c and a sixth tube segment 1150d that are connected in series. The fifth tube segment 1150c has a third opening 1150b. The pressure-limiting plug 115a is slidably and sealingly connected to the inner wall of the fifth tube segment 1150c. The sixth tube segment 1150d is connected to the end of the fifth tube segment 1150c that is away from the third opening 1150b. At least a portion of the inner diameter of the sixth tube segment 1150d is smaller than the inner diameter of the fifth tube segment 1150c. The sixth tube segment 1150d is connected to the third tube segment 112c. By setting the third pressure-limiting tube 1150 as a segmented structure, it is convenient to install the pressure-limiting plug 115a from the end of the fifth tube segment 1150c away from the third opening 1150b into the fifth tube segment 1150c. This design facilitates the filling of fluid 12 into the sixth pipe section 1150d through the end of the sixth pipe section 1150d that is connected to the fifth pipe section 1150c. In other words, after connecting the sixth pipe section 1150d to the connecting pipe 114, fluid 12 can be filled into the sixth pipe section 1150d, and pressure limiting plug 115a can be installed into the fifth pipe section 1150c. Then, the fifth pipe section 1150c and the sixth pipe section 1150d can be connected by threaded connection, welding, or adhesive bonding, without having to connect the third pressure limiting pipe 1150 to the first pressure limiting pipe 110 after the pressure limiting plug 115a is installed and fluid 12 is filled. During the connection process between the third pressure limiting pipe 1150 and the first pressure limiting pipe 110, the filled fluid 12 is prone to overflow, and the connection process is difficult.

[0087] Furthermore, since the inner diameter of at least part of the sixth pipe section 1150d is smaller than the inner diameter of the fifth pipe section 1150c, the pressure relief plug 115a can be confined within the third pressure relief pipe 1150 through the sixth pipe section 1150d, and will not enter the connecting pipe 114 through the sixth pipe section 1150d, thus making the structure and function of the pressure relief assembly 115 more stable.

[0088] Optionally, a guide 115b may be fixedly connected to the side of the pressure limiting plug 115a near the sixth pipe segment 1150d. The end of the guide 115b away from the pressure limiting plug 115a is slidably inserted into the sixth pipe segment 1150d along the sliding direction S. The guide 115b is used to cooperate with the inner wall of the sixth pipe segment 1150d to further guide the sliding direction of the pressure limiting plug 115a, so that the pressure limiting plug 115a keeps sliding relative to the fifth pipe segment 1150c along the sliding direction S, thereby improving the controllability of the sliding direction of the pressure limiting plug 115a.

[0089] Optionally, the guide 115b can be integrally formed with the pressure limiting plug 115a to simplify the preparation and assembly process of the pressure limiting plug 115a and the guide 115b, and to make the connection between the guide 115b and the pressure limiting plug 115a more stable.

[0090] In some embodiments, when the impact force disappears after the first end 10a and the second end 10b move from the initial position to the contracted position, a restoring force can be applied to the pressure limiting plug 115a to make the total force on the pressure limiting plug 115a along the second sub-sliding direction S2 greater than the first threshold. This causes the pressure limiting plug 115a to slide along the second sub-sliding direction S2, thereby squeezing the fluid 12 from the third pressure limiting chamber 1150a into the connecting pipe 114. This, in turn, squeezes a portion of the fluid 12 in the connecting pipe 114 into the first pressure limiting chamber 110a and the second pressure limiting chamber 1150a, respectively. Cavity 112a is used to press the first slider 111 to slide toward the first opening 110b and the second slider 113 to slide toward the second opening 112b. The first slider 111 pushes the first end 10a away from the first opening 110b through the first transmission member 111a, and the second slider 113 pushes the second end 10b away from the second opening 112b through the second transmission member 113a, so that the first end 10a and the second end 10b automatically return to their initial positions from the retracted positions, so that the user can continue to use the button assembly 1 normally.

[0091] Optionally, the pressure relief assembly 115 may further include an elastic element 115c, which may include, but is not limited to, a spring or a sheet. The elastic element 115c is disposed in the third pressure limiting chamber 1150a. One end of the elastic element 115c is connected to the third pressure limiting chamber 1150a, and the other end of the elastic element 115c is connected to the pressure limiting plug 115a. The elastic element 115c is used to apply an elastic force along the sliding direction S to the pressure limiting plug 115a. After the first end 10a and the second end 10b move from the initial position to the contracted position, when the impact force disappears, the elastic element 115c applies an elastic force along the second sub-sliding direction S2 to the pressure limiting plug 115a as a restoring force, thereby pushing the pressure limiting plug 115a to slide along the second sub-sliding direction S2, so that the first end 10a and the second end 10b automatically return to the initial position from the contracted position.

[0092] Optionally, the elastic element 115c can be located on the side of the pressure limiting plug 115a away from the fluid 12. So when the pressure limiting plug 115a slides along the first sub-sliding direction S1, the pressure limiting plug 115a can compress the elastic element 115c between the pressure limiting plug 115a and the third pressure limiting tube 1150. So after the first end 10a and the second end 10b move from the initial position to the contracted position, the elastic element 115c can apply an elastic force along the second sub-sliding direction S2 to the pressure limiting plug 115a. And the elastic element 115c does not directly contact the fluid 12. Therefore, during use, the influence between the elastic element 115c and the fluid 12 is small.

[0093] Considering that the third pressure-limiting chamber 1150a located on the side of the pressure-limiting plug 115a away from the fluid 12 can maintain stable air pressure when connected to the external environment, thus having a smaller impact on the sliding movement of the pressure-limiting plug 115a, optionally, the third pressure-limiting tube 1150 located on the side of the pressure-limiting plug 115a away from the fluid 12 may be provided with a third opening 1150b connected to the third pressure-limiting chamber 1150a. For example, as Figure 1 and Figure 6 As shown, Figure 1 and Figure 6 The diagram shows that one end of the third pressure limiting tube 1150 is connected to the connecting tube 114, and the other end of the third pressure limiting tube 1150 is provided with a third opening 1150b connected to the third pressure limiting cavity 1150a.

[0094] Please see Figure 1 The first threshold is F0. When the first end 10a and the second end 10b are in the initial position, the elastic force applied by the elastic element 115c to the pressure limiting plug 115a is F1. The minimum impact force simultaneously experienced by the first end 10a and the second end 10b is F2. The distance from the contracted position to the initial position is x. The maximum outer diameter r1 of the first slider 111, the maximum outer diameter r2 of the second slider 113, and the maximum outer diameter r3 of the pressure limiting plug 115a are equal. Both the first slider 111 and the second slider 113 are used to slide when the applied force is greater than the second threshold F3. The fluid 12 is a liquid. When the maximum pressing force simultaneously applied by the user to the first end 10a and the second end 10b is F4, in order to... When the pressing force simultaneously applied to the first slider 111 and the second slider 113 is less than or equal to F4, the sliding distance of one of the first slider 111 and the second slider 113 is less than x, and the maximum sliding distance of the other is x. Furthermore, when the impact force simultaneously acting on the first end 10a and the second end 10b is greater than or equal to F2, at the instant that the first end 10a and the second end 10b move as a whole from the initial position to the retracted position, the sliding distance of the first slider 111 and the second slider 113 is x, and the pressure limiting plug 115a receives a total force along the first sub-sliding direction S1 greater than or equal to the first threshold F0. Optionally, the stiffness coefficient k of the elastic element 115c can satisfy:

[0095]

[0096] The units for F0, F1, F2, F3, and F4 are all N.

[0097] Therefore, when the user is using the button assembly 1 normally, the first end 10a and the second end 10b will not move from the initial position to the retracted position as a whole, thus having little impact on the normal use function of the button assembly 1. Moreover, when the impact force simultaneously received by the first end 10a and the second end 10b is the minimum F2, the pressure limiting plug 115a can slide along the first sub-sliding direction S1 to compress the elasticity, thereby causing the first end 10a and the second end 10b to move from the initial position to the retracted position. When the first end 10a and the second end 10b are no longer subjected to the impact force, the elastic restoring force can be released, and this elastic force can push the pressure limiting plug 115a to slide, so that the first end 10a and the second end 10b can automatically return from the retracted position to the initial position.

[0098] It is understandable that the maximum pressing force F4 is less than the minimum impact force F2. Based on the structural strength design of the actual button component 1 and the test results of the user's pressing force, the minimum impact force F2 can usually be approximately 1000N. For example, the minimum impact force F2 can be 700N, 800N, 900N, 1000N, 1100N, 1200N or 1300N, etc. The maximum pressing force F4 can usually satisfy: 5N≤F4≤15N. For example, the maximum pressing force F4 can be 5N, 6N, 7N, 8N, 9N, 10N, 11N, 12N, 13N, 14N or 15N, etc.

[0099] It should be noted that, ideally, the phrase "fluid 12 is liquid" mentioned above means that fluid 12 is entirely liquid. However, in practice, it is difficult to achieve a completely liquid and gas-free filling of fluid 12 due to technological limitations. Furthermore, after a period of use, some liquid leakage or loss will inevitably result in a small amount of gas being present in fluid 12. Therefore, in actual operation, "fluid 12 is liquid" means that most of fluid 12 is liquid, while fluid 12 also includes a small amount of gas. In other words, it means that the volume occupied by liquid in fluid 12 is greater than the volume occupied by gas.

[0100] Optionally, the fluid 12 may include hydraulic oil, so that the fluid 12 is not easily compressible, enabling high-efficiency energy transfer, while also having anti-wear, system lubrication, anti-corrosion, and anti-rust properties.

[0101] In other embodiments, the portion of the third pressure-limiting chamber 1150a on the side of the pressure-limiting plug 115a facing away from the fluid 12 may not be connected to the external environment. Thus, when the pressure-limiting plug 115a slides along the first sub-sliding direction S1, the pressure-limiting plug 115a can compress the gas in this portion of the third pressure-limiting chamber 1150a, causing the gas pressure in this portion of the third pressure-limiting chamber 1150a to increase. After the first end 10a and the second end 10b move from the initial position to the contracted position, this portion of gas can apply pressure to the pressure-limiting plug 115a along the second sub-sliding direction S2, so that the pressure acts as a restoring force to push the pressure-limiting plug 115a to slide along the second sub-sliding direction S2, thereby enabling the first end 10a and the second end 10b to automatically return from the contracted position to the initial position.

[0102] Please refer to the following: Figures 3 to 5 In some embodiments, the button body 10 may include a pressing portion 100, a first elastic connecting portion 101, and a second elastic connecting portion 102. The pressing portion 100 has a first end 10a and a second end 10b. One end of the first elastic connecting portion 101 is connected to the first end 10a, and the other end of the first elastic connecting portion 101 is used to connect to an external structure (e.g., the device body of an electronic device). One end of the second elastic connecting portion 102 is connected to the second end 10b, and the other end of the second elastic connecting portion 102 is used to connect to an external structure (e.g., the device body of an electronic device). A first pressure limiting tube 110 and a second pressure limiting tube are also included. Both 112 are used to connect to the external structure, so that the button body 10, the first pressure limiting tube 110, and the second pressure limiting tube 112 are respectively connected to the external structure. This can reduce the assembly error between the button body 10 and the external structure (such as the device body of an electronic device). It can also enable the pressing part 100 to automatically reset from the retracted position to the initial position independently without being subjected to additional external force, through the first elastic connecting part 101 and the second elastic connecting part 102. This allows the button body 10 to continue to be used as a button even if the anti-linkage mechanism 11 fails to reset.

[0103] Optionally, the pressing part 100 may include a main structural part 100a and a pressing part 100b. A first elastic connecting part 101 and a second elastic connecting part 102 are respectively connected to two opposite ends of the main structural part 100a. The pressing part 100b is located on the side of the main structural part 100a away from the anti-linkage mechanism 11. The pressing part 100b and one end of the main structural part 100a form a first end 10a, and the pressing part 100b and the other end of the main structural part 100a form a second end 10b. The main structural part 100a is used to connect with the first transmission member 111a and the second transmission member 112a. The components 113a exert forces on each other, and the pressing part 100 is used for the user to press. In other words, at least part of the outer surface of the pressing part 100 is exposed to the external use environment, so that the pressing part 100 and the main structural part 100a can be made of different materials respectively, so that the overall structural strength of the pressing part 100 can meet the use requirements through the main structural part 100a, and the range of materials that can be used for the pressing part 100 is wider, so as to provide the user with a better pressing feel, or the appearance color, gloss and texture of the material can meet the design requirements.

[0104] Optionally, the main structural part 100a can be integrally formed with the first elastic connecting part 101 and the second elastic connecting part 102 to simplify the preparation and assembly process of the main structural part 100a, the first elastic connecting part 101 and the second elastic connecting part 102, and to make the connection between the main structural part 100a, the first elastic connecting part 101 and the second elastic connecting part 102 more stable.

[0105] Optionally, the pressing part 100 can be injection molded on one side of the strength part to simplify the preparation and assembly process of the pressing part 100 and the strength part, and to make the connection between the pressing part 100 and the strength part more stable.

[0106] Please refer to the following: Figure 3 and Figure 7In order to output the pressed status of the button assembly 1 to an external circuit via an electrical signal, so that the external circuit can respond to the pressing indication of the first end 10a or the second end 10b of the button assembly 1, in some embodiments, the button assembly 1 may also include a circuit board 13. The circuit board 13 is disposed on the anti-linkage mechanism 11. The circuit board 13 carries a button circuit (not labeled in the figure). The button circuit has a first feed point 130 and a second feed point 131. The first feed point 130 corresponds to the first end 10a, and the second feed point 131 corresponds to the second end 10b. The button circuit is used to be electrically connected to an external circuit. When the first end 10a is pressed, the first end 10a presses against the first feed point 130, so that a first electrical signal is generated at the first feed point 130. The button circuit is used to transmit the first electrical signal to the external circuit. When the second end 10b is pressed, the second end 10b presses against the second feed point 131, so that a second electrical signal is generated at the second feed point 131. The button circuit is used to transmit the second electrical signal to the external circuit.

[0107] The first aspect of the present invention discloses a button assembly 1, which achieves the anti-linkage effect between the first end 10a and the second end 10b of the button body 10 through an anti-linkage mechanism 11.

[0108] Furthermore, when the button body 10 is subjected to an impact, it can distribute the impact force to the first slider 111 and the second slider 113, thereby reducing the pressure generated by the impact force on the first slider 111 and the second slider 113, making the first slider 111 and the second slider 113 less prone to breakage, and improving the overall structural reliability of the button assembly 1.

[0109] Furthermore, this button assembly 1 also includes a pressure relief component 115, which is used to release at least a portion of the fluid 12 filled in the first pressure limiting chamber 110a and the second pressure limiting chamber 112a when the button body 10 is subjected to excessive impact force. This allows the first end 10a and the second end 10b to move from the initial position to the retracted position, thereby retracting into the interior of the electronic device body. This allows the device body to bear the excessive impact force instead of the button assembly 1, thus protecting the structure of the button assembly 1 and extending its service life.

[0110] Please refer to the following: Figure 8 and Figure 9 , Figure 8 This is a three-dimensional structural schematic diagram of the electronic device disclosed in the second aspect of the embodiments of this application. Figure 9 yes Figure 8The electronic device shown is a cross-sectional view along the AA direction. A second aspect of the invention discloses an electronic device 2, which may include, but is not limited to, a mobile phone, tablet computer, portable music player, or headphones. The electronic device 2 includes a device body 20 and at least one button assembly 1 as described in the first aspect above. The button assembly 1 is disposed on the device body 20, such as... Figure 8 As shown, Figure 8 Taking a mobile phone as an example, the three-dimensional structure of an electronic device 2 is illustrated. Because the button assembly 1 has an anti-interlock function and good structural reliability under significant impact, the electronic device 2 has an anti-interlock function for its buttons, and the buttons of the electronic device 2 have a long lifespan.

[0111] like Figure 9 As shown, in some embodiments, the device body 20 may include, for example, a device housing. The device body 20 may have a button hole 200, and the button body 10 of the button assembly 1 may be movably disposed through the button hole 200. A portion of the button body 10 is located inside the device body 20 for connection to the device body 20 (see [link to documentation]). Figure 7 For example, it can be connected to the device body 20 through the first elastic connecting part 101 and the second elastic connecting part 102 as described above. The anti-linkage mechanism 11 is located inside the device body 20, and the first pressure limiting tube 110 and the second pressure limiting tube 112 are fixedly connected to the device body 20. Thus, the button body 10 and the first pressure limiting tube 110 and the second pressure limiting tube 112 are respectively connected to the device body 20, which can reduce the assembly error between the button body 10 and the device body 20.

[0112] It is understood that the button body 10 can also be connected to the device body 20 via a spring, spring sheet, telescopic rod assembly or other connection structure that allows the button body 10 to be movably inserted through the button hole 200. This embodiment does not specifically limit the connection structure between the button body 10 and the device body 20.

[0113] The button assembly and electronic device disclosed in the embodiments of the present invention have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the button assembly and electronic device of the present invention and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
