For those skilled in the art, the specific meaning of the above terms in the embodiments can be understood according to the specific circumstances.

[0028] Specific details are provided in the following description to provide a complete understanding of the exemplary embodiments. However, those skilled in the art will understand that the exemplary embodiments can be implemented without these specific details. For example, the system may be shown in block diagrams to avoid obscuring the example with unnecessary details.

[0029] Example:

[0030] This embodiment provides a command signal press-triggered device with image display, such as... Figures 1 to 8 As shown, the device includes a press-to-display assembly and a micro-switch driving assembly. The press-to-display assembly includes an upper housing 1, a display panel 7, a display control board 9, and a mounting bracket 11. The display panel 7 is embedded at the top of the upper housing 1, and the bottom is open. The mounting bracket 11 is located inside the upper housing 1, and the display control board 9 is fixedly mounted on the mounting bracket 11. The display control board 9 is electrically connected to the display panel 7. The micro-switch driving assembly includes a lower housing 13, a driving board 5, an elastic connection assembly, and a micro switch 4. The driving board 5 is fixedly mounted inside the lower housing 13, and the elastic connection assembly and the micro switch 4 are provided on the driving board 5. The top of the lower housing 13 is open, allowing the elastic connection assembly to form an elastic connection with the mounting bracket 11. The drive board 5 is electrically connected to the micro switch 4. The drive board 5 is provided with a connection socket 16. The connection socket 16 is electrically connected to the display control board 9 through a connection cable 8. The upper housing 1 is movably fitted onto the lower housing 13. The side wall of the lower housing 13 is provided with a limiting pin 12. The side wall of the upper housing 1 is provided with a limiting groove 1A. The limiting pin 12 is inserted into the limiting groove 1A, so that the limiting pin 12 can move in the extension and retraction direction of the elastic connecting component within the limiting groove 1A. The travel of the limiting pin 12 is limited by the limiting groove 1A. The bottom of the mounting bracket 11 is provided with a boss 11A facing the micro switch 4. The boss 11A is used to approach and contact the micro switch 4 when the elastic connecting component is compressed.

[0031] In a specific application, the user can press the upper shell 1 with a finger to compress the elastic connecting assembly, and the limiting pin 12 moves in the limiting groove 1A, and the upper shell 1 and the lower shell 13 slide relative to each other. At this time, the boss 11A at the bottom of the mounting bracket 11 approaches the micro switch 4 opposite to it (the boss 11A is in a disengaged state in a natural state), and when the limiting pin 12 moves to the maximum stroke defined by the limiting groove 1A, the boss 11A contacts the micro switch 4 and triggers the micro switch 4 to send a switch signal to the driving plate 5. After receiving the switch signal of the micro switch 4, the driving plate 5 drives the display control board 9 to work, and the display panel 7 controlled by the display control board 9 displays corresponding images to realize the connection and transmission of the trigger signal and the image display after triggering. When the user releases the finger, the elastic connecting assembly automatically extends to return to the natural state, and the boss 11A leaves the micro switch 4, and the device returns to the original state. The limiting groove 1A limits the maximum stroke of the limiting pin 12 when the elastic connecting assembly is stretched and contracted, which ensures that the micro switch 4 can be triggered and avoids damage to the micro switch 4 caused by excessive stroke when pressing. The limiting groove 1A can match 4 sets of limiting pins 12 and is arranged on the four sides of the upper shell 1 and the lower shell 13.

[0032] Further, the elastic connecting assembly includes a plurality of pairs of spring positioning pins 2 and return springs 3. The spring positioning pins 2 fix the driving plate 5 in the lower shell 13 (for example, four spring positioning pins 2 are arranged, one end of each spring positioning pin 2 penetrates the driving plate 5 and is screwed into the lower shell 13 to fix the driving plate 5), and one end of the return spring 3 is installed on the corresponding spring positioning pin 2 and the other end is connected to the mounting bracket 11. The return compression spring 3 can be a 65Mn spring steel wire with a wire diameter of 0.5 mm. The 65Mn spring steel wire has a shear modulus of 78 Gpa and a permissible shear stress of 584 Mpa. The spring has an outer diameter of 5 mm, a pitch of 2 mm, an effective number of turns of 6 turns, a free length of 11 mm, a minimum load working length of 8 mm, and a maximum load working length of 6 mm. According to the working load calculation model of the cylindrical helical spring, the final return force of a single spring is about 0.5 N, and the return force of four springs is about 2 N. The torque is in the comfortable pressing force range of human fingers. When the device is not pressed, the display assembly is in a jacking state under the action of the return spring 3, the limiting pin 12 contacts the lower limit point of the limiting groove 1A, and the micro switch 4 is in a natural state at this time. When the user presses the device, the boss 11A of the mounting bracket 11 triggers the micro switch 4 to realize the connection and transmission of the signal when the limiting pin 12 contacts the upper limit point of the limiting groove 1A.

[0033] Further, at least two micro switches 4 can be arranged in parallel on the drive plate 5, and the number of the bosses 11A matches the number of the micro switches 4. Through the redundant design of the at least two micro switches 4, the device can work normally in the case of failure of a certain switch. The display control plate 9 is fixedly installed on the mounting frame 11 by M1.6X6 cross groove half-round head screws 6, and the mounting frame 11 is fixedly installed in the upper shell 1 by M1.6X4 cross groove countersunk head screws 10. The upper shell 1 is provided with a transparent protective cover 17 for covering the display panel 7, and the transparent protective cover 17 can be made of high-transparency acrylic plate. After the component is cut, polished and formed according to the size, the display panel 7 is covered by bonding the transparent protective cover 17 with the upper shell 1. The upper shell 1, the mounting frame 11 and the lower shell 13 are all made of 6061-T6 aluminum alloy material, and are processed by machining center processing technology to ensure the shape, size and smoothness of the parts, and the surface is sprayed with fine sand before black non-luster hard anodic oxidation treatment, which improves the wear resistance and surface strength of the product. The inner wall size tolerance of the upper shell 1 is strictly processed to ensure smoothness without jamming when the lower shell 13 is pressed, and the outer wall size tolerance of the lower shell 13 is strictly processed to ensure smoothness without jamming when the upper shell 1 is pressed. In addition, the movable contact surface between the upper shell 1 and the lower shell 13 can be coated with lubricating grease to reduce friction and ensure smoothness when pressed.

[0034] Further, the bottom of the lower shell 13 is provided with a positioning column 13A for positioning and welding on the master control plate. The device can be positioned and welded on the master control plate through the positioning column 13A, so as to realize the integration of multiple devices on the master control plate. The bottom of the drive plate 5 is provided with a first row of pins 14 and a second row of pins 15, and the first row of pins 14 (0.4mm pins) and the second row of pins 15 (0.6mm pins) penetrate the lower shell 13 and are connected to the external master control plate. The drive plate 5 realizes the connection of power signals and logic signals with the master control plate through the first row of pins 14 and the second row of pins 15 respectively.

[0035] Further, the display panel 7 can adopt an OLED display panel, and the display control plate 9 can adopt an OLED display control plate to realize high-definition image display. The drive plate 5 is used for filtering the power signals and logic signals required for driving the display panel. The micro switch 4 selects a KW1 series micro switch, which has a J-level quality grade, can work in the range of-55 to 80℃, has an operating life of not less than 10000 times, a contact impedance of less than 25mΩ, and an insulation impedance of more than 1000MΩ.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
