Description

[0001] This application claims priority to Chinese Patent Application No. 202621207762.3, filed on August 5, 2026, entitled "Push-type Input Device and Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the technical field of electronic devices, and more specifically, to a push-to-put input device and an electronic device. Background Technology

[0003] Press-type input devices are commonly used human-computer interaction components in electronic devices. They are widely used in various electronic products such as keyboards, mice, push-button switches, and control buttons for smart devices. They mainly achieve operations such as command input and function switching by pressing to trigger the corresponding sensing components to output electrical signals.

[0004] Most conventional push-button input devices on the market currently only have a single elastic reset structure with a fixed elastic reset force. The pressing stroke and trigger signal have a one-to-one correspondence, enabling trigger output for a single stroke and a single function. This traditional structure has significant drawbacks in practical use: Firstly, the single elastic structure cannot achieve segmented pressing feel differentiation. The force feedback during pressing is uniform and indistinct, and users cannot intuitively perceive different operating levels through the pressing stroke, making accidental touches and misoperations very easy to occur. Secondly, a single stroke can only trigger a single function signal, only meeting basic on / off and single command input needs, and cannot adapt to the multifunctional and sophisticated interactive control needs of modern electronic products.

[0005] With the functional upgrades of smart electronic devices, users are increasingly demanding higher precision, greater functionality, and improved tactile feedback from key input devices. Segmented pressing and multi-level triggering have become core requirements for high-end input devices. Existing technologies often employ complex multi-level button designs, relying on multiple sets of sensing elements and limiting structures to achieve multi-level triggering. This not only increases the overall size, assembly difficulty, and production cost of the device, but also makes it prone to malfunctions such as jamming, reset failure, and signal triggering disorder, resulting in poor structural stability and lifespan. Summary of the Invention

[0006] The purpose of this invention is to provide a push-button input device and electronic device to solve the technical problems of complex multi-position push-button structure design, poor structural stability and service life in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, a push-button input device is provided, comprising: The housing, a first shaft core and a second shaft core stacked along the pressing direction, a first elastic element connecting the first shaft core and the second shaft core, a second elastic element connecting the second shaft core and the housing, and a sensing component for sensing the first shaft core; The first shaft and the second shaft are movable along the pressing direction, and the elastic forces of the first elastic element and the second elastic element are different; the sensing component outputs a first function signal when the first shaft moves to a first travel range in the pressing direction; the sensing component outputs a second function signal when the first shaft moves to a second travel range in the pressing direction.

[0008] By adopting the above technical solution, this device uses a combination structure of two sets of elastic elements with different elastic forces, namely the first elastic element and the second elastic element, which can accurately distinguish the two pressing strokes without the need for additional limiting structures and sensing elements. Relying on the differentiated elastic force graded structure formed by a single sensing component and the first and second elastic elements, two different functional signals can be output independently and stably. The structural layout is simple and compact, which effectively reduces the assembly difficulty and production cost of the device. At the same time, the graded pressing resistance corresponding to light and heavy presses forms a clear tactile feedback, which is suitable for the fast and precise control habits of gamers. It greatly avoids the problems of accidental touch, misoperation and single function that are easy to occur in traditional single-stroke buttons, and significantly improves the accuracy, sense of layering and user experience of button operation. It can effectively adapt to the multi-functional and refined human-computer interaction needs of input devices such as gaming devices and smart keyboards. The overall structure has strong stability, sensitive stroke trigger response and wider device compatibility.

[0009] In one embodiment, the elastic force gradients of the first elastic element and the second elastic element are matched, and when the first shaft core and the second shaft core are subjected to graded compression along the pressing direction, the first elastic element and the second elastic element can work together to drive the first shaft core to quickly reset.

[0010] In one embodiment, the elastic force of the first elastic element is less than the elastic force of the second elastic element. When the user applies a pressing force matching the first elastic element to the first shaft, the first elastic element compresses, and the first shaft moves to a first stroke range. Then, the user applies a pressing force matching the second elastic element to the first shaft, and the second elastic element compresses again, causing the first shaft to move to a second stroke range. Alternatively... The elastic force of the first elastic element is greater than that of the second elastic element. When the user applies a pressing force matching the second elastic element to the first shaft, the second elastic element is compressed, and the first shaft moves to a first stroke range. When the user applies a pressing force matching the first elastic element to the first shaft, the first elastic element is compressed again, and the first shaft moves to a second stroke range.

[0011] In one embodiment, the push-to-feed input device further includes a sensing element disposed on the first shaft core, the sensing component being used to acquire the position of the sensing element in order to output the first function signal and the second function signal.

[0012] In one embodiment, the sensing component includes a magnetic induction sensor, a photoelectric sensor, a capacitive sensor, or a contact sensor.

[0014] In one embodiment, the cover is provided with a shaft hole, and the first shaft core is clearance-fitted with the shaft hole and exposed in the shaft hole.

[0015] In one embodiment, the first shaft core is provided with a first protrusion structure in the circumferential direction, and the cover is provided with a first limiting structure for limiting the first protrusion structure around the shaft hole.

[0016] In one embodiment, the first shaft core is provided with a second protrusion structure in the circumferential direction, and the second shaft core is provided with a second limiting structure in the circumferential direction for limiting the second protrusion structure.

[0017] In a second aspect, an electronic device is provided, comprising an electronic device body and the aforementioned push-to-put input device. The electronic device body includes a keyboard body, a mouse body, a remote control body, a control panel body, a vehicle steering wheel body, a vehicle central control body, or a navigation device body; the push-to-put input device is disposed on the electronic device body.

[0018] By adopting the above-mentioned new technical solution, this press-type input device can be adapted and integrated into the main body of various types of electronic devices, expanding the application scenarios of the hierarchical press-type input structure. This enables various conventional input, control, vehicle and navigation equipment to achieve dual-function control of light press and heavy press, improving the operational precision and multi-functional interactive performance of various electronic devices. The structure has wide adaptability and strong versatility. Attached Figure Description

[0022] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating relative importance or the number of technical features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this invention will be described in more detail below with reference to specific embodiments: like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a push-to-put input device, comprising: The housing 1, the first shaft core 2 and the second shaft core 3 stacked along the pressing direction X, the first elastic element 4 connecting the first shaft core 2 and the second shaft core 3, the second elastic element 5 connecting the second shaft core 3 and the housing 1, and the sensing component 6 for sensing the first shaft core 2; The first shaft core 2 and the second shaft core 3 are movable along the pressing direction X, and the elastic forces of the first elastic element 4 and the second elastic element 5 are different; the sensing component 6 outputs a first function signal when the first shaft core 2 moves to the first travel range of the pressing direction X; the sensing component 6 outputs a second function signal when the first shaft core 2 moves to the second travel range of the pressing direction X.

[0026] The specific structure of the above technical solution is as follows: This push-type input device mainly consists of a housing 1, a first shaft core 2 and a second shaft core 3 stacked along the pressing direction, a first elastic element 4 and a second elastic element 5 with different elastic parameters, and a sensing component 6 that senses the displacement state of the first shaft core 2. The first shaft core 2 and the second shaft core 3 can move relative to each other along the pressing axis and are assembled as a whole inside the housing 1. The first elastic element 4 is correspondingly assembled between the first shaft core 2 and the second shaft core 3 to realize the elastic connection and relative reset between the first shaft core 2 and the second shaft core 3. The second elastic element 5 is correspondingly assembled between the second shaft core 3 and the housing 1 to realize the elastic support and overall reset of the second shaft core 3 relative to the housing 1. The sensing component 6 is arranged to match the displacement path of the first shaft core 2 and can monitor the pressing stroke position of the first shaft core 2 in real time and output different functional signals accordingly. The overall structure relies on the elastic difference of the first elastic element 4 and the second elastic element 5 in combination with the stacked movement structure of the double-layer shaft core to form a two-stage pressing stroke structure that can be accurately distinguished.

[0027] Please refer to the following: Figure 3 and Figure 4 Its working principle is as follows: This device can be widely used in input device scenarios such as keyboards and game buttons, especially suitable for game device button control. During game interaction, players can switch between different control functions by distinguishing between light and heavy presses. Specifically, when a player lightly presses a button, the press travel corresponds to the first travel range. Utilizing the difference in elasticity between the first elastic element 4 and the second elastic element 5, the initial light press force can only overcome the resistance of the elastic element with less elasticity, driving the first axis core 2 to move relative to the second axis core 3. At this time, the first axis core 2 moves to the preset first travel range. The sensing component 6 detects this displacement state and stably outputs the first function signal, which can correspond to basic game functions such as regular movement, selection, and normal click. Operational Functions: When the player presses the button hard, the pressing force increases further, and the pressing stroke corresponds to the second stroke range. The continuous pressing force can overcome the combined resistance of the first elastic element 4 and the second elastic element 5, driving the first shaft core 2 and the second shaft core 3 to move synchronously relative to the housing 1, so that the first shaft core 2 enters a deeper second stroke range. Based on this depth displacement state, the sensing component 6 outputs a second function signal that is different from the first function signal, which can correspond to the advanced game operation functions such as skill release, quick combo, view switching, and precise confirmation. Throughout the process, through the differentiated matching of pressing force and stroke, and in conjunction with the graded resistance characteristics of the first elastic element 4 and the second elastic element 5, the two functions are precisely distinguished and triggered, meeting the diversified control needs of game operation.

[0028] By adopting the above technical solution, this device uses a combination structure of two sets of elastic elements with different elastic forces, namely the first elastic element 4 and the second elastic element 5, stacked with a double-layer shaft core. It can accurately distinguish the two pressing strokes without adding additional limiting structures and sensing elements. Relying on the differentiated elastic force graded structure formed by the single sensing component 6 and the first elastic element 4 and the second elastic element 5, it can realize the independent and stable output of two different functional signals. The structural layout is simple and compact, which effectively reduces the assembly difficulty and production cost of the device. At the same time, the graded pressing resistance corresponding to light and heavy presses forms a clear tactile feedback, which is suitable for the fast and accurate control habits of gamers. It greatly avoids the problems of accidental touch, misoperation and single function that are easy to occur in traditional single-stroke buttons. It significantly improves the accuracy, sense of layering and user experience of button operation. It can effectively adapt to the multi-functional and refined human-computer interaction needs of input devices such as gaming devices and smart keyboards. The overall structure has strong stability, sensitive stroke trigger response and wider device compatibility.

[0029] In one embodiment, the elastic force gradients of the first elastic element 4 and the second elastic element 5 are matched. When the first shaft core 2 and the second shaft core 3 are subjected to graded compression along the pressing direction X, the first elastic element 4 and the second elastic element 5 can work together to drive the first shaft core 2 to quickly reset.

[0030] Specifically, the structure of the above technical solution is as follows: the first shaft core 2 and the second shaft core 3 are stacked and assembled along the pressing direction X; the first elastic element 4 is connected between the first shaft core 2 and the second shaft core 3; the second elastic element 5 is connected between the second shaft core 3 and the housing 1; the elastic forces of the first elastic element 4 and the second elastic element 5 are different and their elastic force gradients are matched; during the pressing process, the first shaft core 2 and the second shaft core 3 can be sequentially compressed in stages along the pressing direction X; the first elastic element 4 and the second elastic element 5 accumulate elastic potential energy respectively with the compression deformation of the corresponding shaft core; the sensing component 6 can identify the stroke position of the first shaft core 2 in real time and output the first function signal or the second function signal accordingly.

[0031] Its working principle is as follows: When the user applies pressure, the first elastic element 4 is compressed first, causing the first shaft core 2 to enter the first stroke range, depending on the magnitude of the pressure. If the pressure is further increased, the second elastic element 5 is compressed accordingly, causing the first shaft core 2 to enter the second stroke range. When the user removes part of the pressure without fully releasing the button to the initial position, the first elastic element 4, which has undergone compression deformation, directly applies a reverse rebound force to the first shaft core 2, and the second elastic element 5, which has undergone compression deformation, applies a reverse rebound force to the second shaft core 3. Relying on the layered transmission cooperation between the first shaft core 2 and the second shaft core 3, the first elastic element 4 and the second elastic element 5 form a coordinated rebound effect, jointly driving the first shaft core 2 to move back, reducing the frictional resistance and motion hysteresis during the shaft core movement, shortening the reset response time of the first shaft core 2, so that the first shaft core 2 can quickly return to the usable stroke position that can trigger the signal again without having to fully return to the initial zero position of the button.

[0032] By adopting the above technical solution, while fully retaining the hierarchical input function of the first shaft core 2 outputting the first functional signal when it moves to the first stroke range and outputting the second functional signal when it moves to the second stroke range, the structure of the first elastic element 4 and the second elastic element 5 with elastic force gradient matching is used to achieve coordinated drive reset. The rebound force released by the first elastic element 4 and the rebound force released by the second elastic element 5 are superimposed and compensated for each other, avoiding the problem of weak rebound caused by relying on the rebound of a single elastic element. In gaming devices, the RT value, or key repetition response time, is a core parameter for measuring the continuous pressing response speed of keys. A smaller RT value indicates faster key rebound and higher continuous pressing efficiency. This solution significantly shortens the key reset interval through the coordinated rebound structure of the first elastic element 4 and the second elastic element 5, effectively accelerating and optimizing the RT value in game operations, significantly reducing the time loss during the key reset phase, and improving the overall key response sensitivity. Users can quickly execute the re-press action by slightly releasing the key. The key action has low latency, supports high-frequency continuous input and fast pressing operations under short-stroke conditions, and is suitable for high-intensity control scenarios with game combos and rapid alternating triggers. It reduces operational errors caused by rebound lag, while ensuring a clear distinction between light and heavy press tactile feedback, balancing the graded press input function with the responsiveness and operational stability of key operations.

[0033] In one embodiment, the elastic force of the first elastic element 4 is less than the elastic force of the second elastic element 5. When the user applies a pressing force matching the first elastic element 4 to the first shaft core 2, the first elastic element 4 is compressed and the first shaft core 2 moves to a first stroke range. When the user applies a pressing force matching the second elastic element 5 to the first shaft core 2, the second elastic element 5 is compressed again and the first shaft core 2 moves to a second stroke range.

[0034] Specifically, the core structure newly added to the above technical solution is as follows: Compared with the traditional single elastic element and single stroke triggering press input structure, this solution adds a graded press structure with double-layer shaft core stacked and double elastic element with differentiated elastic force. Specifically, the elastic force relationship is defined as the elastic force of the first elastic element 4 being less than that of the second elastic element 5. The first elastic element 4 is independently assembled between the first shaft core 2 and the second shaft core 3, and is only responsible for the elastic reset of the first shaft core 2 relative to the second shaft core 3. The second elastic element 5 is independently assembled between the second shaft core 3 and the housing 1, and is responsible for the elastic reset of the second shaft core 3 and the overall structure. Through the matching and cooperation of the two sets of first elastic elements 4 and second elastic elements 5 with different elastic force gradients and the first shaft core 2 and second shaft core 3 that can be relatively displaced, a brand-new two-level segmented press stroke structure is formed. At the same time, relying on the original sensing component 6 to match the newly added two-level stroke structure, the precise triggering of the single sensing component 6 corresponding to the dual stroke and dual function signal is realized. This is the core new technical feature that distinguishes it from the traditional structure.

[0035] Its working principle is as follows: This solution is based on a newly added dual-elastic force gradient structure to realize a brand-new graded triggering logic. When the user or gamer presses the button, a small pressing force matching the elastic force of the first elastic element 4 is applied. This force can only overcome the weaker elastic force of the first elastic element 4, causing it to compress and deform. The second elastic element 5, due to its higher elastic force threshold, does not deform due to insufficient force. The second axis core 3 remains fixed, and only the first axis core 2 moves independently and is within the first stroke range. The sensing component 6 outputs the first function signal to realize the basic function of light pressing. When the user applies a larger pressing force matching the elastic force of the second elastic element 5, the force of the second elastic element 5 can be further overcome to compress and deform it. This causes the second axis core 3 to move synchronously with the first axis core 2, allowing the first axis core 2 to enter a deeper second stroke range. The sensing component 6 outputs the second function signal accordingly. Through the newly added two-level elastic force gradient structure, the precise correspondence and differentiation of pressing force, pressing stroke, and function signal are realized, meeting the differentiated operation needs of light pressing and heavy pressing of game buttons and multi-functional keyboards.

[0036] By adopting the above-mentioned new technical solution, this solution breaks through the technical limitations of traditional buttons with single elastic force, single stroke, and single function by adding a first elastic element 4 and a second elastic element 5 with different elastic forces and a double-layer movable shaft core. It utilizes the difference in elastic force between the first elastic element 4 and the second elastic element 5 to form two levels of pressing thresholds, and can achieve dual-function triggering without adding sensing elements and limiting structures. The new structure is simple and highly adaptable. It retains the advantages of button miniaturization and adds the core performance of segmented pressing feel and multi-level function triggering. It effectively solves the problems of traditional buttons with no operation distinction, easy accidental touch, and single function, greatly improves the sense of layering, accuracy and product functionality of pressing input, and significantly expands the applicable scenarios and performance of pressing input devices.

[0037] In one embodiment, the elastic force of the first elastic element 4 is greater than the elastic force of the second elastic element 5. When the user applies a pressing force matching the second elastic element 5 to the first shaft core 2, the second elastic element 5 is compressed, and the first shaft core 2 moves to a first stroke range. When the user applies a pressing force matching the first elastic element 4 to the first shaft core 2, the first elastic element 4 is compressed again, and the first shaft core 2 moves to a second stroke range.

[0038] Specifically, the structure of the above-mentioned new technical solution is as follows: Compared with the traditional single elastic element single stroke button structure, this solution innovatively sets up a first shaft core 2 and a second shaft core 3 arranged in layers along the pressing direction X. The first elastic element 4 is connected between the first shaft core 2 and the second shaft core 3, and the second elastic element 5 is connected between the second shaft core 3 and the housing 1. Furthermore, the elastic force of the first elastic element 4 is limited to be greater than that of the second elastic element 5. Relying on the two sets of elastic elements with different elastic forces, a two-level pressing motion structure is formed by combining the relatively movable double-layer shaft core. The sensing component 6 monitors the position of the first shaft core 2 and outputs the corresponding functional signal according to its different stroke range. Relying on the above-mentioned differentiated elastic force matching double-layer shaft core combination configuration, a graded pressing trigger architecture that is different from the existing technology is formed.

[0039] Its working principle is as follows: Based on the newly added structure, a two-stage progressive pressing logic is formed. When the user or player applies a small pressing force to the first axis core 2 that matches the elastic force of the second elastic element 5, the external force overcomes the elastic force of the second elastic element 5, causing the second elastic element 5 to compress. The load on the first elastic element 4 is insufficient to cause compression. The first axis core 2 moves synchronously with the second axis core 3 to the first stroke range. The sensing component 6 outputs the first function signal to realize the basic control function corresponding to the light press. As the pressing force is continuously increased, a larger pressing force matching the elastic force of the first elastic element 4 is applied to the first axis core 2. Under the premise that the second elastic element 5 is kept in a compressed state, the external force further overcomes the elastic force of the first elastic element 4, causing the first elastic element 4 to compress. The first axis core 2 continues to move relative to the second axis core 3 and enters the second stroke range. The sensing component 6 outputs the second function signal to realize the advanced control function corresponding to the heavy press. Relying on the elastic force gradient, the two sets of elastic elements are driven to deform in sequence, realizing the sequential triggering of the two strokes and different operation commands corresponding to different forces.

[0040] By adopting the aforementioned new technical solution, this solution utilizes a first elastic element 4 with greater elasticity and a second elastic element 5 with less elasticity, arranged in a graded manner. Together with the first shaft core 2 and the second shaft core 3, which can be relatively displaced, a progressive two-stage pressing structure is constructed. It can achieve dual-stroke, dual-function signal output without adding multiple sets of sensing components and complex limiting structures. The innovative change in the elasticity arrangement of the two-stage elastic elements forms a motion logic of first moving as a whole and then sliding relative to each other, bringing a brand-new segmented pressing feel. It can clearly distinguish between light and heavy press operations, solving the drawback of traditional pressing input devices that only have a single trigger level and cannot achieve graded force control. The structural changes are concentrated on the shaft core assembly relationship and the elasticity configuration of the elastic elements. The overall structure is simple and compact, easy to assemble, and compatible with keyboards, game control buttons, and other products, expanding the application capabilities of multi-level interaction of pressing input devices.

[0041] In one embodiment, the push-to-use input device further includes a sensing element 7 disposed on the first shaft core 2, and the sensing component 6 is used to obtain the position of the sensing element 7 to output a first function signal and a second function signal.

[0042] Specifically, the structure of the above-mentioned new technical solution is as follows: Compared with the traditional single elastic element single stroke button structure, this solution innovatively sets up a first shaft core 2 and a second shaft core 3 arranged in layers along the pressing direction X. The first elastic element 4 is connected between the first shaft core 2 and the second shaft core 3, and the second elastic element 5 is connected between the second shaft core 3 and the housing 1. The elastic force of the first elastic element 4 is limited to be greater than that of the second elastic element 5. A sensing element 7 is set on the first shaft core 2, and a sensing component 6 is arranged accordingly. The sensing component 6 identifies the stroke range of the first shaft core 2 by acquiring the real-time position information of the sensing element 7 and outputs the corresponding functional signal. A two-stage pressing motion structure is formed by relying on the two sets of elastic elements with different elastic forces and the relatively movable double-layer shaft core. The hierarchical pressing trigger architecture that is different from the existing technology is formed by relying on the above-mentioned differentiated elastic forces, double-layer shaft cores, and the cooperative configuration of sensing element 7 and sensing component 6.

[0043] Its working principle is as follows: Based on the newly added structure, a two-stage progressive pressing logic is formed. When the user or gamer applies a small pressing force to the first axis core 2, matching the elastic force of the second elastic element 5, the external force overcomes the elastic force of the second elastic element 5, causing the second elastic element 5 to compress. The load on the first elastic element 4 is insufficient to cause compression. The first axis core 2 moves synchronously with the second axis core 3 to the first stroke range. The sensing component 6 collects the position signal of the sensing element 7 and outputs the first function signal to realize the basic control function corresponding to the light press. By continuously increasing the pressing force, a larger pressing force matching the elastic force of the first elastic element 4 is applied to the first axis core 2. Under pressure, while the second elastic element 5 remains compressed, the external force further overcomes the elastic force of the first elastic element 4, causing the first elastic element 4 to compress. The first shaft core 2 continues to move relative to the second shaft core 3 and enters the second stroke range. The sensing component 6 collects the new position information of the sensing element 7 and outputs the second function signal to realize the advanced control function corresponding to the heavy press. Relying on the elastic gradient, the two sets of elastic elements are driven to deform in sequence. The sensing element 7 moves synchronously with the first shaft core 2. The sensing component 6 realizes the two strokes are triggered in sequence by recognizing the different positions of the sensing element 7, and different operation commands are corresponding to different forces.

[0044] By adopting the aforementioned new technical solution, this solution utilizes a first elastic element 4 with greater elasticity and a second elastic element 5 with less elasticity, arranged in a tiered manner. Combined with a first shaft core 2 and a second shaft core 3 that can be relatively displaced, a progressive two-stage pressing structure is constructed. A sensing element 7 is integrated into the first shaft core 2. The sensing component 6 distinguishes the pressing level by capturing the positional changes of the sensing element 7. This eliminates the need for additional sensing components and complex limiting structures, achieving dual-stroke, dual-function signal output. The innovative change in the elasticity arrangement of the two-stage elastic elements creates a motion logic of first overall movement and then relative sliding, resulting in a completely new segmented pressing feel. It clearly distinguishes between light and heavy presses, solving the drawback of traditional pressing input devices that only have a single trigger level and cannot achieve graded force control. The sensing element 7 moves synchronously with the first shaft core 2, providing direct position acquisition and stable signal response. The overall structural changes are concentrated on the shaft core assembly relationship, elastic element elasticity configuration, and sensing component layout. The structure is simple and compact, easy to assemble, and compatible with keyboards, game control buttons, and other products, effectively expanding the multi-level interactive application capabilities of pressing input devices.

[0045] In one embodiment, the sensing component 6 includes a magnetic sensing element, a photoelectric sensing element, a capacitive sensing element, or a contact sensing element.

[0046] Specifically, the structure of the above-mentioned new technical solution is as follows: Compared with the traditional single elastic element single stroke button structure, this solution innovatively sets up a first shaft core 2 and a second shaft core 3 arranged in layers along the pressing direction X. The first elastic element 4 is connected between the first shaft core 2 and the second shaft core 3, and the second elastic element 5 is connected between the second shaft core 3 and the housing 1. Furthermore, the elastic force of the first elastic element 4 is limited to be greater than that of the second elastic element 5. This device also adds a sensing element 7 on the first shaft core 2. The matching sensing component 6 can be any one of magnetic induction sensing element, photoelectric sensing element, capacitive sensing element or contact sensing element. The sensing component 6 accurately determines the different stroke ranges of the first shaft core 2 by acquiring the displacement position information of the sensing element 7 in real time and outputs the first function signal and the second function signal accordingly. Relying on the two sets of first elastic elements 4 and second elastic elements 5 with different elastic forces, combined with the relatively movable double-layer shaft core structure, the sensing element 7 and the multiple types of selectable sensing components 6 constitute a graded pressing precise triggering architecture that is different from the existing technology.

[0047] Its working principle is as follows: Based on the newly added structure, a two-stage progressive pressing logic is formed. When the user or gamer applies a small pressing force to the first axis core 2, matching the elastic force of the second elastic element 5, the external force overcomes the elastic force of the second elastic element 5, causing the second elastic element 5 to compress. The load on the first elastic element 4 is insufficient to cause compression deformation. The first axis core 2 moves synchronously with the second axis core 3 to the first stroke range. The sensing component 6 identifies the current position of the sensing element 7 on the first axis core 2 and outputs the corresponding first function signal to realize the basic control function corresponding to the light press. By continuously increasing the pressing force, a larger pressing force matching the elastic force of the first elastic element 4 is applied to the first axis core 2, and the second elastic element 5 is maintained under compression. Under the premise of the state, the external force further overcomes the elastic force of the first elastic element 4, causing the first elastic element 4 to compress. The first shaft core 2 continues to move relative to the second shaft core 3 and enters the second stroke range. The sensing component 6 collects the displacement position change of the sensing element 7 again and outputs a second function signal that is different from the first function signal, realizing the advanced control function corresponding to the heavy press. Relying on the difference in elastic force gradient between the first elastic element 4 and the second elastic element 5, the two sets of elastic elements are driven to deform progressively. With the characteristic of the sensing element 7 moving synchronously with the first shaft core 2, and with the multi-type compatible sensing component 6, the two stroke positions are accurately identified, realizing the graded triggering effect of different operating commands corresponding to different pressing pressure.

[0048] By adopting the aforementioned new technical solution, this solution uses a differentiated arrangement structure of a first elastic element 4 with greater elasticity and a second elastic element 5 with less elasticity. Combined with a double-layer shaft core that can be relatively displaced, it constructs a progressive two-stage pressing structure that first moves as a whole and then slides relative to each other. At the same time, a sensing element 7 is integrated into the first shaft core 2, and the sensing component 6 is configured with multiple selectable sensing forms such as magnetic sensing element, photoelectric sensing element, capacitive sensing element, and contact sensing element to adapt to the sensing assembly and triggering requirements of different products. It can stably achieve dual-stroke, dual-function signal output without adding multiple sets of sensing components and complex limiting structures. It effectively solves the shortcomings of traditional pressing input devices that only have a single trigger level, cannot achieve graded force control, and have poor adaptability of sensing structure. The newly added sensing and cooperating structure has direct position acquisition, stable signal response, and wide applicability. The overall innovative structure is simple and compact, easy to assemble, and highly reliable. It can be well adapted to various multi-functional pressing input products such as keyboards and game control buttons, greatly expanding the multi-level interactive performance and product compatibility range of pressing input devices.

[0049] Please refer to the following: Figure 5 In one embodiment, the housing 1 includes a base 11 and a cover 12 covering the base 11; the base 11 is provided with a guide sleeve 13, the guide sleeve 13 is provided with a first guide groove 131, one end of the second shaft core 3 is clearance-fitted with the first guide groove 131, the second shaft core 3 is provided with a second guide groove 31, one end of the first shaft core 2 is clearance-fitted with the second guide groove 31, and the other end of the first shaft core 2 protrudes outside the cover 12.

[0050] Specifically, the structure of the above-mentioned new technical solution is as follows: Compared with the traditional single-elastic-element single-stroke button structure, the housing 1 consists of a base 11 and a cover 12 covering the base 11. The base 11 is provided with a guide sleeve 13, which has a first guide groove 131. One end of the second shaft core 3 is clearance-fitted with the first guide groove 131. The second shaft core 3 is provided with a second guide groove 31. One end of the first shaft core 2 is clearance-fitted with the second guide groove 31, and the other end of the first shaft core 2 protrudes outside the cover 12. The first shaft core 2 and the second shaft core 3 are stacked along the pressing direction X. The first elastic element 4... The first shaft core 2 is connected to the second shaft core 3. The second elastic element 5 connects the second shaft core 3 to the housing 1. The elastic force of the first elastic element 4 is greater than that of the second elastic element 5. The first shaft core 2 is provided with a sensing element 7. The sensing component 6 can be a magnetic sensing element, a photoelectric sensing element, a capacitive sensing element, or a contact sensing element. The sensing component 6 obtains the position of the sensing element 7, determines the stroke range of the first shaft core 2, and outputs the corresponding first function signal and second function signal. The graded press triggering architecture is formed by relying on the double-layer guide structure, the relatively movable double shaft cores, and the two sets of elastic elements with different elastic forces.

[0051] Its working principle is as follows: the first guide groove 131 of the guide sleeve 13 and the second guide groove 31 of the second shaft core 3 guide and limit the second shaft core 3 and the first shaft core 2 respectively, ensuring that the shaft core moves smoothly along the pressing direction; when the user or player presses the first shaft core 2 exposed on the cover 12 and applies a small pressing force matching the elastic force of the second elastic element 5, the external force compresses the second elastic element 5, the first elastic element 4 does not deform temporarily, and the first shaft core 2 moves synchronously with the second shaft core 3 to the first stroke range. The sensing component 6 identifies the position of the sensing element 7 and outputs the first function signal to realize the basic light press operation; continue to increase the pressing force to match the elastic force of the first elastic element 4, and compress the first elastic element 4 while keeping the second elastic element 5 compressed. The first shaft core 2 continues to move relative to the second shaft core 3 into the second stroke range. The sensing component 6 outputs the second function signal to realize the advanced heavy press operation. The progressive two-level pressing is realized by using the elastic force difference between the two sets of elastic elements, and different operation levels are distinguished by the position change of the sensing element 7.

[0052] By adopting the above-mentioned new technical solution, the double-layer guide structure can limit the offset of the shaft core, avoid pressing and jamming, and improve the stability of movement. The first elastic element 4 with greater elasticity and the second elastic element 5 with less elasticity cooperate to form a two-stage pressing stroke of first overall movement and then relative sliding. With the sensing element 7 located on the first shaft core 2 and various optional types of sensing components 6, two functional signals can be output independently with only one set of sensing cooperation structure. There is no need to add additional limit and sensing parts. The structure is simplified and the assembly is simple. It overcomes the defects of traditional buttons that only have a single trigger position and cannot be controlled in stages. It can be adapted to keyboards, game control buttons and other products.

[0053] In one embodiment, the cover 12 is provided with a shaft hole 121, and the first shaft core 2 is clearance-fitted with the shaft hole 121 and exposed in the shaft hole 121.

[0054] Specifically, the structure of the above-mentioned new technical solution is as follows: the new cover 12 of this solution has a shaft hole 121, the first shaft core 2 is clearance-fitted with the shaft hole 121 and exposed in the shaft hole 121.

[0055] Its working principle is as follows: the shaft hole 121 forms a radial limit on the first shaft core 2, guiding the first shaft core 2 to move stably along the pressing direction X. The user can press the end of the first shaft core 2 exposed by the shaft hole 121 to input the operating force.

[0056] By adopting the above-mentioned new technical solution, the shaft hole 121 can constrain the radial sway of the first shaft core 2, improve the smoothness of the pressing motion, and at the same time, the shaft hole 121 allows the first shaft core 2 to extend out, forming an operating part that can be directly pressed by the user. The structure is simple and easy to assemble.

[0057] In one embodiment, a first protrusion structure 21 is provided on the circumference of the first shaft core 2, and a first limiting structure 122 for limiting the first protrusion structure 21 is provided on the periphery of the shaft hole 121 of the cover body 12.

[0058] Specifically, the structure of the above-mentioned new technical solution is as follows: the solution adds a first protruding structure 21 to the first shaft core 2 in the circumferential direction, and the cover 12 is provided with a first limiting structure 122 for limiting the first protruding structure 21 on the periphery of the shaft hole 121.

[0059] Its working principle is as follows: When the first shaft core 2 is pressed down, the first protrusion structure 21 moves synchronously with the first shaft core 2. When the first shaft core 2 is reset upward to the limit position, the first protrusion structure 21 can abut against the first limiting structure 122 to restrict the first shaft core 2 from continuing to come out.

[0060] By adopting the above-mentioned new technical solution, the first protrusion structure 21 and the first limiting structure 122 form an axial limiting fit, which can prevent the first shaft core 2 from falling out of the shaft hole 121 of the cover body 12. There is no need to add additional independent buckle parts, simplifying the assembly structure and improving the overall assembly stability of the device.

[0061] In one embodiment, the first shaft core 2 is provided with a second protrusion structure 22 protruding in the circumferential direction, and the second shaft core 3 is provided with a second limiting structure 32 for limiting the second protrusion structure 22 in the circumferential direction.

[0062] Specifically, the structure of the above-mentioned new technical solution is as follows: the solution adds a second protruding structure 22 to the first shaft core 2 in the circumferential direction, and a second limiting structure 32 that can limit the second protruding structure 22 in the circumferential direction to the second shaft core 3.

[0063] Its working principle is as follows: when the first shaft core 2 moves axially relative to the second shaft core 3, the second protrusion structure 22 moves synchronously with the first shaft core 2. The second protrusion structure 22 can abut against the second limiting structure 32, thereby restricting the first shaft core 2 from detaching from the second shaft core 3.

[0064] By adopting the above-mentioned new technical solution, the axial positioning between the first shaft core 2 and the second shaft core 3 is achieved by the cooperation of the second protrusion structure 22 and the second limiting structure 32, which prevents the first shaft core 2 from sliding out of the second shaft core 3, ensures that the double-layer shaft core always maintains the assembled state, has strong structural integrity, and reduces the use of independent limiting accessories.

The electronic device body includes a keyboard body, a mouse body, a remote control body, a control panel body, a vehicle steering wheel body, a vehicle central control body, or a navigation device body; the push-to-put input device is disposed on the electronic device body.

[0066] Specifically, the structure of the above-mentioned new technical solution is as follows: This solution adds an electronic device, including an electronic device body and the aforementioned push-type input device mounted on the electronic device body, wherein the electronic device body can be any one of a keyboard body, mouse body, remote control body, control panel body, vehicle steering wheel body, vehicle central control body or navigation equipment body.

[0067] Its working principle is as follows: a press-type input device with dual-stroke and dual-function graded press triggering function is integrated and installed on the main body of various electronic devices. Through the light press and heavy press graded press operation of the press-type input device, different functional signals are output to meet the multi-level control input needs of the corresponding electronic devices.

[0068] By adopting the above-mentioned new technical solution, this press-type input device can be adapted and integrated into the main body of various types of electronic devices, expanding the application scenarios of the hierarchical press-type input structure. This enables various conventional input, control, vehicle and navigation equipment to achieve dual-function control of light press and heavy press, improving the operational precision and multi-functional interactive performance of various electronic devices.
