Description

Technical Field

[0001] This utility model relates to the field of keyboard device technology, and in particular to a visual keypad device. Background Technology

[0002] Keyboards are one of the most common human-computer interaction input devices, widely used in computers, mobile terminals, smart devices, and other fields. Traditional keyboards mainly consist of multiple physical keys, and input signals are collected through mechanical triggering, capacitive sensing, and other methods. Their structure is mature and their response is stable.

[0003] A visual keyboard is an input device that combines a display unit with keyboard keys. Each key can display graphic and text information independently or uniformly. It supports dynamic switching of the displayed content according to the current application environment, user habits, or functional requirements, thereby improving the intuitiveness and flexibility of user operation.

[0004] However, traditional visual keyboards have poor tactile feedback and lack a clear rebound feel, making it difficult for users to accurately judge whether the key has been triggered when pressing it. This leads to operational uncertainty and can easily cause accidental or missed key presses. Utility Model Content

[0005] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a visual button device, which solves at least one of the above-mentioned technical problems and has the advantage of increasing the tactile feedback of the buttons, thus improving the customer experience.

[0006] To achieve the above objectives, this utility model provides a visual button device, comprising:

The side wall of the contact point is connected to the hole wall of the mounting through hole through an elastic connector.

[0010] A detection component is disposed at the bottom of the button frame;

[0011] Specifically, when the button body is pressed, the bottom of the button body pushes the contact point toward the detection component. When the contact point comes into contact with and is squeezed by the detection component, a sensing signal is triggered. When the button body is not pressed, the button body is reset under the action of the elastic support member, and the contact point is reset under the action of the elastic connector.

[0012] Optionally, the trigger is provided in four groups around the elastic support, and a sensing signal is triggered when all four groups of the contact points of the elastic support are in contact with the detection component.

[0015] Optionally, the elastic connector is made of silicone.

[0016] Optionally, the device includes a housing, which comprises a detachably connected front shell and a bottom shell. When the front shell and the bottom shell are connected, they enclose an internal installation space. The bottom shell has snap-fit ​​blocks on its opposite side walls, and the front shell has a snap-fit ​​groove adapted to the snap-fit ​​blocks on the side of the front shell closest to the bottom shell.

When the button body does not press the contact point, the bottom of the contact point is higher than the bottom of the mounting through hole, and the top of the contact point is higher than the top of the mounting through hole. When the button body presses the contact point to contact the detection component, the bottom of the contact point is lower than the bottom of the mounting through hole, and the top of the contact point is higher than or parallel to the top of the mounting through hole.

[0020] Optionally, the detection component is electrically connected to the display component, the detection component is a conductive film, and the display component is one of a TFT display screen, an LCD display screen, an OLED display screen, or an LED dot matrix module.

In addition, the terms "first" and "second" are only used to distinguish multiple parts or structures with the same or similar structures, and do not indicate any special limitation on the arrangement order or connection relationship.

[0043] Please refer to Figures 1 to 8 This utility model provides a visual button device, including: a button body 100, a button frame 200, a trigger 300, and a detection component 400. At least one button body 100 is provided. An elastic support 210 is provided on the top of the button frame 200, and the button body 100 is mounted on the elastic support 210 and can be reciprocated by pressing and resetting through the elastic support 210. Multiple triggers 300 are provided on the top of the button frame 200 and surrounding the elastic support 210. Each trigger 300 includes a mounting through hole 310, and a contact 320 passes through the mounting through hole 310. The sidewall of the contact 320 is connected to the wall of the mounting through hole 310 via an elastic connector 330. The detection component 400 is located at the bottom of the button frame 200.

[0044] When the button body 100 is pressed, the bottom of the button body 100 pushes the contact point 320 toward the detection component 400. When the contact point 320 contacts the detection component 400, a sensing signal is triggered. When the button body 100 is not pressed, the button body 100 resets under the action of the elastic support member 210, and the contact point 320 resets under the action of the elastic connector 330. The button body 100 refers to an independent structural component with a pressing function, which can be injection molded from plastic, metal, or composite materials. Its function is to receive the user's pressing action and transmit pressure.

[0045] Furthermore, the button frame 200 refers to the support structure that supports the button body 100 and the trigger 300. Specifically, it can be implemented using an integrally injection-molded frame structure, and its function is to provide a fixed foundation for the elastic support 210 and the trigger 300. The elastic support 210 refers to a structure that provides vertical elastic deformation, and can be implemented using silicone material. Its function is to achieve the pressing feedback of the button body 100 through deformation and reset. The trigger 300 refers to a signal triggering unit that includes a contact 320 and an elastic connector 330. The elastic connector 330 refers to an elastic element that connects the contact 320 to the wall of the mounting through hole 310, and can be implemented using a silicone sheet. Its function is to maintain the initial position of the contact 320 and reset it after the pressure is released. The contact 320 detection component 400 refers to a sensing module used to receive the displacement signal of the contact 320.

[0046] When the button body 100 is pressed, the bottom of the button body 100 pushes the contact 320 toward the detection component 400. At this time, the contact 320, while being pushed, also applies a reaction force to the button body 100, thereby increasing the button's press feel. When the contact 320 contacts the detection component 400, a sensing signal is triggered. When the button body 100 is not pressed, the button body 100 resets under the action of the elastic support 210, and the contact 320 resets under the action of the elastic connector 330. During the reset process, the contact 320 can act on the button body 100, increasing the rebound feel of the button body 100, making the rebound feel of the button body 100 clearer and reducing the occurrence of accidental and missed presses.

[0047] In this embodiment, four sets of trigger elements 300 are arranged around the elastic support 210. A sensing signal is triggered when all four sets of contacts 320 of the elastic support 210 are in contact with the detection component 400. Further, the trigger elements 300 are divided into four groups and arranged in a ring around the elastic support 210. A contact 320 passes through the mounting through hole 310 of each set of trigger elements 300, and the sidewall of the contact 320 is connected to the wall of the mounting through hole 310 via an elastic connector 330. The trigger signal condition is set so that all four sets of contacts 320 simultaneously contact the detection component 400. Specifically, when the button body 100 is pressed, its bottom applies uniform pressure to the four sets of contacts 320, pushing the contacts 320 to move downwards synchronously. The elastic connector 330 undergoes tensile deformation under pressure, allowing the contacts 320 to move axially along the mounting through hole 310. When all four sets of contacts 320 simultaneously contact the detection component 400, the detection component 400 is triggered. If only some of the contacts 320 are in contact, the detection component 400 will ignore signals that have not reached the threshold. When the button body 100 resets, the elastic support 210 pushes it upward, and the rebound force of the elastic connector 330 causes the contacts 320 to disengage from the detection component 400. The symmetrical layout of the four sets of contacts 320 can offset the problem of asynchronous contact caused by off-center pressing, reducing the risk of accidental touch.

[0048] In this embodiment, an exhaust plate 600 is provided at the bottom of the detection component 400. The exhaust plate 600 is located below the detection component 400. The exhaust plate 600 may have multiple through holes or a mesh structure to allow gas or heat to escape through the through holes. The exhaust plate 600 may be made of metal or thermally conductive plastic.

[0049] In this embodiment, a display component 800 is disposed at the bottom of the exhaust plate 600. The display component 800 includes one of a TFT display screen, an LCD display screen, an OLED display screen, or an LED dot matrix module. The display component 800 and the detection component 400 are electrically connected through a flexible circuit board or conductive lines. Specifically, when the button body 100 is pressed, the contact point 320 contacts the detection component 400 to trigger a sensing signal. The detection component 400 transmits the electrical signal to the display component 800, and the display component 800 switches the display content according to a preset program. The detection component is a conductive film, which includes a first silver paste layer and a second silver paste layer screen-printed sequentially from top to bottom. When the contact point contacts and presses the detection component, the first silver paste layer and the second silver paste layer come into contact and emit a signal.

[0050] In this embodiment, the elastic connector 330 is made of silicone. Furthermore, silicone possesses high elastic modulus and fatigue resistance; its cross-linked molecular chain structure can withstand repeated deformation without permanent deformation. The chemical stability of silicone makes it resistant to aging under long-term exposure to air or mechanical friction, thus maintaining the mechanical properties of the elastic connector 330.

[0051] In this embodiment, the housing 500 includes a detachably connected front shell 510 and a bottom shell 520. When the front shell 510 and the bottom shell 520 are connected, they enclose an internal installation space. A snap-fit ​​block 521 is provided on each of the opposite side walls of the bottom shell 520, and a snap-fit ​​groove 522 adapted to the snap-fit ​​block 521 is provided on the side of the front shell 510 closest to the bottom shell 520. Furthermore, the front shell 510 and the bottom shell 520 are detachably connected via the snap-fit ​​block 521 and the snap-fit ​​groove 522. The snap-fit ​​blocks 521 are symmetrically distributed in the middle of the side walls of the bottom shell 520. The height of the installation space matches the total thickness of the internally stacked parts. Specifically, when maintenance of the internal components is required, an external force is applied vertically to disengage the snap-fit ​​block 521 from the snap-fit ​​groove 522, thus separating the front shell 510 from the bottom shell 520. During installation, align the snap-fit ​​groove 522 of the front cover 510 with the snap-fit ​​block 521 of the bottom cover 520 and press down until the snap-fit ​​block 521 is fully embedded in the snap-fit ​​groove 522.

[0052] In this embodiment, the faceplate 510 is provided with at least one first visible through hole 710, the button frame 200 is provided with a second visible through hole 720 corresponding to the first visible through hole 710, the detection component 400 is provided with a third visible through hole 730 corresponding to the second visible through hole 720, and the exhaust plate 600 is provided with a fourth visible through hole 740 corresponding to the third visible through hole 730. The first visible through hole 710, the second visible through hole 720, the third visible through hole 730, and the fourth visible through hole 740 are combined to form a visible channel. Furthermore, the front shell 510 and the bottom shell 520 are detachably connected by a snap-fit ​​block 521 and a snap-fit ​​groove 522, facilitating the disassembly and maintenance of internal components; the first visible through-hole 710, the second visible through-hole 720, the third visible through-hole 730 and the fourth visible through-hole 740 are aligned in sequence to form a visible channel penetrating the shell 500, ensuring that the content of the display component 800 can be seen through the channel; the elastic support member 210 is set around the second visible through-hole 720, and the button body 100 is made of transparent or semi-transparent material to further optimize the light transmission effect. Combined with the layout of the elastic support member 210 around the second visible through-hole 720, the light transmission area is avoided from being blocked.
