Description

Technical Field

[0001] This utility model relates to the field of trigger button technology, specifically to a button that can be triggered by the edge. Background Technology

[0002] In aircraft control panel design, physical buttons play an irreplaceable role in mission-critical control due to their high reliability and clear tactile feedback. However, a common but often overlooked problem is that many operators tend to press the edges of buttons rather than the center. This habit can render traditionally designed buttons ineffective, posing a potentially significant threat to the reliability and safety of flight missions. Therefore, we urgently need a new type of button that can solve this problem. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a button that can be triggered by the edge to solve the technical problem that existing aircraft trigger buttons can only be triggered by the center and cannot be triggered by pressing the edge, resulting in invalid button triggering and affecting the reliability and safety of aircraft control panel operation.

[0004] According to the technical solution provided in the embodiments of this application, a button that can be triggered by the edge includes a button body, the upper part of which is snapped into the mounting groove of the button panel, and the bottom part abuts against the elastic button on the PCB board. The button body includes a button key, a wave-shaped rubber spring, and a compensation spring block; The wave-shaped rubber spring has a rectangular ring structure and is mounted on the base of the button by snapping on the bottom skirt. The bottom of the skirt has a protrusion that snaps into the groove of the base. The compensation spring block has a cylindrical structure and is snapped into a slot at the bottom of the button to trigger the elastic button on the PCB board.

[0005] Furthermore, the main body of the corrugated rubber spring is provided with multiple elliptical notches, which are evenly distributed along the circumference of the corrugated rubber spring body. These notches are used for the contraction of the corrugated rubber spring body along the pressing direction, reducing lateral expansion and avoiding friction with the side wall of the mounting groove.

[0006] Furthermore, the width of the button opening is greater than that of the button key, and the distance between the button opening and the button key is 0.1-0.5mm, preferably 0.25mm, and the opening width of the button opening is smaller than that of the mounting groove.

[0007] Furthermore, the inner side of the through hole has an arc-shaped chamfer.

[0008] Furthermore, the width of the wave-shaped rubber spring is greater than the width of the button.

[0009] Furthermore, the top of the corrugated rubber spring abuts against the top of the mounting groove.

[0010] Furthermore, the width of the base is greater than the width of the button, while the width of the base is less than the width of the mounting slot.

[0011] Furthermore, the button panel is fixed to the PCB board by bolts.

[0012] Furthermore, the wave-shaped rubber spring is made of high-damping silicone rubber, which has good elasticity and damping characteristics.

[0013] In summary, the beneficial effects of this application are as follows: 1. The button can be triggered by pressing its edge, so that the kinetic energy of the operator pressing the button edge is converted into the elastic potential energy of the wave-shaped rubber spring, and then the elastic potential energy of the wave-shaped rubber spring is converted into the kinetic energy of the compensation spring, thereby triggering the button. 2. By setting a wave-shaped rubber spring on the outside of the button, the high-damping silicone rubber is made into a wave-like spring, thereby converting the kinetic energy when pressing the edge of the button into elastic potential energy. When contracted, the wave-shaped rubber spring can compress the volume to avoid friction with the side wall, preventing the button from getting stuck in the button panel. It can also be used as a buffer for the button's rebound. Third, the button openings on the button panel use a combination of chamfers and rounded corners, which makes the deflection of the button when it is triggered at the edge smoother. In addition, this tapered design makes the horizontal frame of the button smaller, reducing the occurrence of offset. Fourth, by setting a small-diameter compensation spring at the bottom of the button body, the compensation spring allows the button body to work on keypads of different depths, thus expanding the applicability of the button body. 5. The button is connected to the wave-shaped rubber spring and the button is also connected to the compensation spring block, so that the button body has a fitting design, which improves the reliability and stability of the button during use.

Detailed Implementation

[0016] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] A button that can be triggered via the edge, such as Figure 1 and Figure 2 As shown, it includes a button body 1, the upper part of which is snapped into the mounting groove 201 of the button panel 2, and the bottom part abuts against the elastic button 301 on the PCB board 3, so that multiple bolts pass through the screw holes provided on the button panel 2, and the button panel 2, the button body 1 and the PCB board 3 are assembled and fixed by the nut at the bottom.

[0019] like Figure 4 and Figure 5As shown, the button body 1 includes a button 101, a corrugated rubber spring 102, and a compensating spring block 103. The bottom of the button 101 and the corrugated rubber spring 102 are provided with a skirt 1021. The skirt 1021 can be glued and fixed to the bottom base of the button 101 using RTV glue. The bottom of the skirt 1021 is also provided with a protrusion 1022, so that the protrusion 1022 can be snapped into the groove 1012 on the base 1011 of the button 101, thereby improving the connection stability of the button body 1. At the same time, the addition of the skirt 1021 increases the contact area between the skirt 1021 of the corrugated rubber spring 102 and the surface of the base 1011 of the button 101, thus improving the reliability of use.

[0020] like Figure 6 and Figure 7 As shown, the main body of the wave-shaped rubber spring 102 has a rectangular ring structure, and multiple elliptical notches 1023 are provided on the main body. The multiple elliptical notches 1023 are evenly distributed along the circumference of the main body of the wave-shaped rubber spring 102. They are used for the contraction of the main body of the wave-shaped rubber spring 102 along the pressing direction, converting the kinetic energy of pressing the edge of the button 101 into the elastic potential energy of the button 101 on the side wave-shaped rubber spring 102. After the finger is released, the elastic potential energy is converted into the kinetic energy of the button itself, which can successfully trigger the elastic switch. At the same time, the wave-shaped rubber spring 102 contracts along the pressing direction after being pressed, while its expansion in the horizontal and vertical directions of the pressing direction is small. This structure of the wave-shaped rubber spring 102 effectively avoids the situation where the wave-shaped rubber spring 102 expands outwards when the edge of the button 101 is pressed, causing friction with the side wall, and preventing the button 101 from getting stuck in the mounting groove 201, which would prevent the button 101 from being triggered normally.

[0021] like Figure 8 As shown, the button panel 2 is provided with a button opening 202, and the inner side of the button opening 202 has an arc-shaped chamfer. The width of the button opening 202 is greater than that of the button key 101. The distance between the button opening 202 and the button key 101 is 0.1-0.5mm, preferably 0.25mm. At the same time, the opening width of the button opening 202 is smaller than the width of the mounting groove 201. The button opening 202 on the button panel 2 uses a combination of chamfer and rounded corners, which allows the button key 101 to deflect more smoothly when triggered at the edge. In addition, this tapered design makes the horizontal frame of the button key 101 smaller, reducing the occurrence of offset.

[0022] like Figure 3 and Figure 4As shown, the compensation spring block 103 has a cylindrical structure and is snapped into the groove 1012 at the bottom of the button key 101. It is glued and fixed by RTV adhesive. By setting the compensation spring block 103 with a diameter smaller than that of the elastic button 301 at the bottom of the button body 1, the compensation spring block 103 allows the button body 1 to work on the button plate at different depths, thus expanding the applicability of the button body 1.

[0023] like Figure 8 As shown, button 101 is snapped into the corrugated rubber spring 102, and button 101 is snapped into the compensating spring block 103, so that the button body 1 has a fitting design in its structure, which improves the reliability and stability of the button when in use.

[0024] The working principle of this edge-triggered button is as follows: Existing physical buttons, when pressed at their edges, cause the button to pop up and collide hard with the button board, wasting most of the kinetic energy and preventing proper PCB signal triggering. Therefore, a button that can be triggered by its edge is proposed. A specially designed wave-shaped rubber spring 102 is placed on the outer side of the button 101 on the button body 1. When the user presses the edge of the button 101, the kinetic energy is stored as elastic potential energy in the wave-shaped rubber spring 102. The moment the finger is released, this elastic potential energy is released, causing the spring piece inside the elastic button 301 on the PCB to deform through the compensation spring block 103, successfully triggering the signal. The recoil after the spring piece deforms is absorbed by the self-damping of the wave-shaped rubber spring 102, thus meeting the usage requirements of the elastic button 301. The weight of a single button is generally around 30g. According to my country's "Airworthiness Standards for Transport Category Aircraft", the limit load factor for positive overload (pull-up) is 2.5G, the limit load factor for negative overload (pull-up lever) is 1G, and the limit load factor for lateral (roll + yaw) is ±1G. During this process, the limit overload force on the button is approximately 0.735N, which is much less than the minimum triggering force of the button (for industrial elastic buttons 301, the minimum triggering force is generally 3-5N). This provides sufficient redundancy and prevents false triggering, thereby improving the reliability of the button during use.

[0025] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
