Description

Technical Field

[0001] The utility model relates to an integrated button structure, which is particularly applied to the control panel in the defense fields such as airplanes, ships, armored vehicles, etc., and belongs to the technical field of high-reliability human-computer interaction. Background Art

[0002] In the fields such as airplanes, ships, armored vehicles, etc., buttons, indicator lights, buzzers, and display screens play important input and output roles; the traditional backlit button integrates the functions of a button and an indicator light, but the traditional backlit button has a large volume and a low degree of integration. With the increasing demand for information integration of various types of equipment, the traditional backlit button can no longer well adapt to the development of the times. Summary of the Invention

[0003] The purpose of the utility model is: to provide an integrated button structure.

[0004] In order to achieve the above purpose, the technical solution of the utility model provides an integrated button structure, which includes a key shaft and a base. It is characterized in that a guiding hole is arranged on the key shaft, and the guiding hole is sleeved on the guiding shaft arranged on the base, and the key shaft can axially slide in a small range along the guiding shaft; a first buckle is arranged on the key shaft, which cooperates with a second buckle arranged on the base to limit the position, preventing the key shaft from separating from the base.

[0005] Preferably, a guide rail is arranged on the key shaft, and a guide groove is arranged on the base, and the guide groove restricts the circumferential rotation of the guide rail. If a guide groove is arranged on the key shaft and a guide rail is arranged on the base, the same effect can be achieved.

[0006] Preferably, the above solution further includes a sealing sleeve, one end of the sealing sleeve is sleeved on the key shaft, and the other end is sleeved on the base.

[0007] Preferably, the above solution further includes a key cap and a circuit board component. The key cap is sleeved on the key shaft, forming a fully enclosed or semi-enclosed cavity with the key shaft. The circuit board component is arranged in this cavity. A micro switch is arranged on the circuit board component, and the micro switch contacts the end face of the guiding shaft.

[0008] Preferably, a functional element is arranged on the circuit board component, and this functional element can be a light-emitting diode or a buzzer or a display screen, as well as a combination of the foregoing functional elements.

[0009] The utility model provides an integrated button structure, which is exquisitely structured and has a much smaller volume than the traditional backlit button; this button structure can integrate light-emitting diodes, buzzers, display screens and their corresponding various combinations, with rich integrated functions, and can provide customers with various highly integrated options.
