Description

Technical Field

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

[0002] Currently, the three-way buttons widely used in the consumer electronics field are mainly dial buttons. For example, the buttons on the control box of headphones usually use a U-shaped three-way dial switch. This three-way dial switch switches internal contacts by rotating the dial, and uses different contact combinations to connect the corresponding circuits to realize the switching of the function level; it also supports vertical pressing to trigger additional functions (such as start / stop).

[0003] However, this type of three-way rotary switch, which achieves control by tossing or pressing an arc-shaped button, often has the following problems: First, the arc-shaped button creates a large gap between its curved structure and the product's casing, which negatively impacts the product's appearance and structural compatibility; second, the rotary switch requires the product's shape to match the switch's curvature, affecting the overall aesthetics; and finally, from a user experience perspective, the arc-shaped button can only be tossed along its curved trajectory, making operation uncomfortable.

[0004] Therefore, there is an urgent need for a button device and electronic device to solve the above-mentioned technical problems. Summary of the Invention

[0005] Based on the above, the purpose of this invention is to provide a button device and electronic device that, while realizing the three-way control function of the button, can reduce the gap between the button and the product shell, improve the product's aesthetics, and enhance the user experience.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The button device includes:

[0008] The housing has a button hole on its side wall and a support wall inside the housing that is opposite to the button hole.

[0009] The circuit board is fixed inside the housing;

[0010] A tactile switch is fixed on the circuit board and electrically connected to the circuit board;

[0011] A sliding switch is fixed on the circuit board and electrically connected to the circuit board;

[0012] A button is slidably disposed at the button hole along a first direction. The button includes a pressing part, a flange part, a trigger part, and a connecting part. The pressing part faces the outside of the housing, the flange part is engaged with the inside of the button hole, and the trigger part and the connecting part both extend from the flange part into the inside of the housing. When the button is in the triggered position, the trigger part is opposite to the position of the tactile switch. The connecting part is connected to the sliding handle of the slide switch.

[0013] A spring sheet is elastically disposed between the flange and the support wall. The fixed part of the spring sheet is fixed to the flange, and the deformable part of the spring sheet is slidably connected to the support wall.

[0014] In some possible implementations, the button device further includes a reinforcing plate fixed to the surface of the support wall, a spring elastically disposed between the flange and the reinforcing plate, and the deformable portion of the spring slidingly connected to the reinforcing plate.

[0015] In some possible implementations, the fixing portion of the spring is bonded to the flange portion; and / or, the reinforcing piece is bonded to the support wall.

[0016] In some possible implementations, the connecting portion includes two claws disposed on the flange portion, the sliding handle is engaged between the two claws in a first direction, and the two claws and the sliding handle are slidably connected in a pressing direction; and / or, the trigger portion is a columnar structure disposed on the flange portion.

[0017] In some possible implementations, a positioning post is also provided on the flange, and a positioning hole is provided on the support wall. When the button is in the trigger position, the positioning post and the positioning hole are positioned opposite each other.

[0018] In some possible implementations, the surface of the flange facing the keyhole, the inner wall surface of the housing in contact with the flange, and the outer wall surface of the housing surrounding the keyhole are all parallel to each other.

[0019] In some possible implementations, the tactile switch and the slide switch are respectively fixed to both sides of the circuit board; the support wall is provided with a clearance notch, the trigger part passes through the clearance notch and cooperates with the tactile switch, and the connecting part passes through the clearance notch and connects with the slide handle.

[0020] In some possible implementations, the housing includes a detachably connected first housing and a second housing, with the keyhole located at the junction of the first housing and the second housing.

[0022] Electronic devices, including the button devices described in any of the above embodiments.

[0023] The beneficial effects of this invention are:

[0024] The button device provided by this invention, when the button is in the triggered position, allows the trigger part of the button to press against a tactile switch by vertically pressing the button, thereby triggering the tactile switch to control the start and stop of the electronic device. When the button is slid along a first direction, the connecting part of the button can drive the sliding handle of the sliding switch to move, thereby triggering the sliding switch to control functions such as volume of the electronic device. In addition, after the pressing operation stops, the spring can realize the immediate reset of the button, and the fixed part of the spring is fixedly connected to the button, while the deformable part of the spring is slidably connected to the support wall, allowing the spring to slide synchronously with the button along the first direction, avoiding interference with the sliding of the button and making the sliding of the button smoother. The button device of this invention realizes three-way control function through vertical pressing and planar sliding of the button, and the flatness of this sliding button relative to the housing is better, reducing the assembly gap between the button and the housing, improving the integrity and aesthetics of the product appearance, and improving the user experience.

[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] Existing electronic products typically use dial buttons for three-way control. The curved structure of the dial button creates two types of gaps between itself and the product casing: First, a static gap occurs when the curvature of the product's shape does not match the curvature of the dial, and the larger the curvature difference, the more noticeable the gap, especially on flat products. Second, an additional dynamic gap must be reserved to meet the operation requirements of the dial button's scrolling trigger. The combination of these two factors results in a significant gap in products using dial buttons, negatively impacting both the product's aesthetic integrity and structural adaptability.

[0042] To address the aforementioned issues, embodiments of the present invention provide a button device that can be applied to headphone control boxes or other electronic devices to reduce the gap between the button and the casing, thereby improving product aesthetics and enhancing user experience.

[0043] like Figures 1 to 10As shown, the button device in this embodiment includes a housing 1 and a circuit board 2, a tactile switch 3, a slide switch 4, a button 5, and a spring 6 disposed within the housing 1. A button hole 11 is provided on the side wall of the housing 1, and the button 5 is slidably disposed at the button hole 11 along a first direction. In this embodiment, the first direction specifically refers to the length direction of the button 5. Optionally, the housing 1 includes a first housing 101 and a second housing 102 that are detachably connected. The button hole 11 is disposed at the joint between the first housing 101 and the second housing 102. This arrangement facilitates the installation of components such as the circuit board 2, the button 5, and the spring 6, improving assembly efficiency. Specifically, during assembly, the circuit board 2, the button 5, the spring 6, and other components can be first installed inside the first housing 101, and then the second housing 102 can be snapped and fixed to the first housing 101. In this embodiment, the circuit board 2 is fixed to the first housing 101 by a fixing post, and the tactile switch 3 and the slide switch 4 are respectively fixed to the circuit board 2, and both the tactile switch 3 and the slide switch 4 are electrically connected to the circuit board 2. The button 5 includes a pressing part 51, a flange part 52, a trigger part 53, and a connecting part 54. The pressing part 51 faces the outside of the housing 1 to facilitate pressing and sliding operations by the user; the flange part 52 is disposed on the outer periphery of the pressing part 51 and is engaged with the inside of the button hole 11 to prevent the button 5 from falling out of the button hole 11; the trigger part 53 and the connecting part 54 both extend from the flange part 52 into the inside of the housing 1. The trigger part 53 cooperates with the tactile switch 3 to trigger the tactile switch 3; the connecting part 54 is connected to the sliding handle 41 of the slide switch 4 to trigger the slide switch 4. A support wall 12 is also provided inside the first housing 101, opposite to the position of the button hole 11. A spring 6 is elastically disposed between the flange part 52 and the support wall 12, and the spring 6 is used to reset the button 5 after it is pressed. Specifically, the spring 6 includes a fixing part 61 and a deformable part 62. The fixing part 61 is fixedly connected to the flange part 52, and the deformable part 62 slides in contact with the support wall 12. When the button 5 slides along the first direction, it can drive the spring 6 to move synchronously along the first direction, thereby causing the deformable part 62 to slide on the support wall 12. In this embodiment, the button 5 has a trigger position, a first position, and a second position during its stroke along the first direction. The first position and the second position are located on both sides of the trigger position. When the button 5 is in the trigger position, the trigger part 53 is opposite to the position of the tactile switch 3. At this time, pressing the button 5 vertically can cause the trigger part 53 to abut against and trigger the tactile switch 3, thereby realizing the control of the start and stop of the electronic device. During the process of the button 5 being flipped to the first position or the second position, the connecting part 54 can drive the sliding handle 41 of the sliding switch 4 to slide synchronously, thereby triggering the sliding switch 4, thereby realizing the control of the volume and other functions of the electronic device.

[0044] The button device in this embodiment achieves three-way control through vertical pressing and planar sliding of button 5. Furthermore, the sliding button 5 has better flatness relative to the housing 1, reducing both the static and dynamic gaps between the button 5 and the housing 1, thus improving the product's overall appearance and aesthetics, and enhancing the user experience. It avoids the problem of excessive gaps associated with using dial buttons. This button device is particularly suitable for products with a flat housing.

[0045] As button 5 moves along the first direction, it causes the spring 6 fixed to it to move as well. The deformable portion 62 of the spring 6 slides in contact with the support wall 12. Therefore, moving button 5 causes friction between the spring 6 and the support wall 12. Excessive friction can damage the support wall 12, potentially preventing button 5 from sliding properly. Furthermore, pressing button 5 applies pressure to the spring 6, causing it to deform and accumulate elastic potential energy. Upon releasing button 5, the spring 6 releases this elastic potential energy, pushing button 5 back to its original position. During pressing, the deformable portion 62 expands outwards when in contact with the support wall 12, and retracts inwards during release. This expansion and contraction of the spring 6 also causes friction between the deformable portion 62 and the support wall 12. Excessive friction can damage the support wall 12, further preventing button 5 from sliding properly. To address the aforementioned issues, the button device in this embodiment further includes a reinforcing plate 7. The reinforcing plate 7 is fixed to the surface of the support wall 12, and a spring plate 6 is elastically disposed between the flange portion 52 and the reinforcing plate 7. The deformable portion 62 of the spring plate 6 is slidably connected to the reinforcing plate 7. By providing the reinforcing plate 7, this embodiment can protect the surface of the support wall 12, preventing excessive wear and extending the service life of the button device. Furthermore, the reinforcing plate 7 is made of polytetrafluoroethylene (PTFE). PTFE reinforcing plates 7 have a low coefficient of friction and good wear resistance, effectively reducing frictional wear between the spring plate 6 and the reinforcing plate 7, and improving product lifespan.

[0046] Optionally, the spring 6 is made of metal. Metal springs have strong fatigue resistance and wear resistance, are not easily deformed or aged, and are suitable for high-frequency operation scenarios; moreover, metal springs can provide clear tactile and auditory feedback, improving the user experience. Specifically, the spring 6 can be made of stainless steel and manufactured through a stamping process. Optionally, the fixing part 61 of the spring 6 and the flange part 52 are fixed together with double-sided adhesive, ensuring reliable connection and convenient assembly. In addition, the reinforcing plate 7 is also fixed to the support wall 12 by adhesive to ensure the smoothness of the surface of the reinforcing plate 7, facilitating the sliding of the spring 6 on the reinforcing plate 7.

[0047] Optionally, the connecting part 54 includes two claws 541 disposed on the flange part 52. The sliding handle 41 is engaged between the two claws 541 in a first direction. With this configuration, when the button 5 slides to the first position, one of the claws 541 can push the sliding handle 41 to move. When the button 5 slides to the second position, the other claw 541 can push the sliding handle 41 to move in the opposite direction, thereby realizing the control of the slide switch 4. Furthermore, there is a movable gap between the end of the claw 541 and the housing of the slide switch 4. The two claws 541 are slidably connected to the sliding handle 41 in the pressing direction, so that when the button 5 is pressed, the claws 541 can slide relative to the sliding handle 41, thereby ensuring the smooth operation of the pressing operation.

[0048] Optionally, in this embodiment, the trigger part 53 is a columnar structure disposed on the flange part 52. Pressing the tactile switch 3 via the columnar structure ensures precise and sensitive operation. Furthermore, the flange part 52 is also provided with a positioning post 55, and the support wall 12 is provided with a positioning hole 121. When the button 5 is in the trigger position, the positioning post 55 and the positioning hole 121 are opposite each other. By pressing the button 5 vertically, the positioning post 55 can be inserted into the positioning hole 121, thus achieving the positioning of the trigger position of the button 5 and making the triggering of the tactile switch 3 by the button 5 more precise. It should be noted that when the button 5 is slid along the first direction, causing the button 5 to deviate from the trigger position, due to the abutting action between the positioning post 55 and the support wall 12, even if the button 5 is pressed, it cannot be pressed down, and therefore the tactile switch 3 will not be triggered. Furthermore, when the button device is equipped with a reinforcing plate 7, a clearance hole that communicates with the positioning hole 121 is also required on the reinforcing plate 7 so that the positioning pin 55 can pass through the clearance hole and be inserted into the positioning hole 121.

[0049] In this embodiment, the surface of the flange 52 facing the keyhole 11, the inner wall surface of the housing 1 in contact with the flange 52, and the outer wall surface of the housing 1 surrounding the keyhole 11 are all arranged parallel to each other. This parallel structural relationship fundamentally reduces the assembly gap between the key 5 and the housing 1, improves the flatness of the housing 1, and avoids the problem of excessive gap caused by using a dial button.

[0050] Optionally, in this embodiment, the tactile switch 3 and the slide switch 4 are respectively fixed on both sides of the circuit board 2, while the trigger part 53 and the connecting part 54 are spaced apart on the flange part 52 along the second direction, so that the trigger part 53 can correspond to the tactile switch 3 and the connecting part 54 can correspond to the slide switch 4. It should be noted that the second direction in this embodiment is the width direction of the button 5, and the second direction is perpendicular to the first direction. Further, the support wall 12 is provided with a clearance notch 122, and both the trigger part 53 and the connecting part 54 move within the clearance notch 122. The trigger part 53 passes through the clearance notch 122 to cooperate with the tactile switch 3, and the connecting part 54 passes through the clearance notch 122 to connect with the sliding handle 41.

[0051] This embodiment also provides an electronic device including the aforementioned button device. The button device has a three-way control function: when using the press function, pressing the button 5 vertically triggers the tactile switch 3 to control the product; when using the slide function, moving the button 5 to the first or second position moves the slide switch 4 to control the product. Applying this button device to an electronic device can reduce the gap between the housing 1 and the button 5, improving the product's aesthetics and enhancing the user experience. Specifically, this electronic device can be a headphone control box.
