Description

Technical Field

[0001] This invention belongs to the technical field of push-button switches, and relates to a push-button switch with an OLED display screen. Background Technology

[0002] Programmable push-button switches are widely used in multi-function command panels of control systems and are an important component of the control station command panel. In existing programmable push-button switches, the control circuit board detects a change in the button signal state and sends the corresponding button state image data stored on an external SD card to a monitoring terminal such as a computer via a data bus for display. This means that the button switch's operating status can only be viewed on the monitoring terminal. Once away from the monitoring terminal, in the actual working environment of the push-button switch, personnel cannot intuitively and conveniently view its operating status.

[0003] Therefore, in view of the shortcomings of existing push-button switches that cannot intuitively display their working status in real time, this invention discloses a push-button switch with an OLED display screen. Summary of the Invention

[0004] The purpose of this invention is to provide a button switch with an OLED display screen, which can transmit the corresponding image to the OLED display screen in real time according to the button switch's pressed state, thereby enabling the button switch itself to intuitively and conveniently display its own working status.

[0005] This invention is achieved through the following technical solution:

[0006] A push-button switch with an OLED display includes a housing. Inside the housing, a self-resetting push-button switch and a switch position detection circuit board are disposed. The button end of the self-resetting push-button switch is connected to the inner wall of the housing via a snap-fit ​​structure, and the pin of the self-resetting push-button switch is connected to the switch position detection circuit board. An OLED display is disposed on the outer side of the housing and connected to the output end of the switch position detection circuit board.

[0007] The image to be displayed on the OLED screen is formatted and sized according to specifications and stored in external memory, which is then connected to a switch position detection circuit board. When the casing is pressed, the casing, through a snap-fit ​​structure, causes the button of the self-reset button switch to depress. This depressing of the self-reset button switch activates the switch position detection circuit board. Once the switch position detection circuit board detects this change in the button signal, it sends the image corresponding to the current depressing state of the self-reset button switch from the external memory to the OLED screen for display. This allows the display content to switch depending on the depressing scenario of the self-reset button switch.

[0008] To better realize the present invention, the outer shell further includes a base and a top cover that is movably fastened to the top of the base. A fastening structure is provided between the inner top of the top cover and the button end of the self-reset button switch. An OLED display screen is provided on the top of the fastening structure.

[0009] To better realize the present invention, the fastening structure further includes a fastening plate, the bottom of which is provided with a first fastening part that fastens with the button end of the self-resetting button switch, and the edge of which is provided with a second fastening part that fastens with the inner wall of the top cover.

[0010] To better realize the present invention, the bottom of the fastener plate is provided with a fastening groove that engages with the button end of the self-resetting button switch. A first fastening opening is provided on the side wall of the fastening groove, and a first fastening part is provided between the first fastening opening and the top of the button end of the self-resetting button switch.

[0011] To better realize the present invention, a second fastening opening is provided on the side wall of the top cover, and at least one second fastening part is provided on both sides of the fastening plate to fasten with the second fastening opening.

[0012] To better realize the present invention, the top of the fastener plate is provided with a display screen support surface, the top of the display screen support surface is provided with an OLED display screen, and the top of the top cover is provided with a transparent window corresponding to the OLED display screen.

[0013] To better realize the present invention, a limiting groove is further provided between the display support surface and the OLED display screen, and a connecting cable is provided inside the limiting groove. The OLED display screen is connected to the switch position detection circuit board through the connecting cable.

[0014] To better realize the present invention, the base is further provided with a receiving cavity, the receiving cavity is provided with a switch position detection circuit board, and a third fastening part is provided between the side wall of the receiving cavity and the switch position detection circuit board.

[0015] To better realize the present invention, the bottom of the base is provided with a plurality of pin holes, and the pins of the switch position detection circuit board extend to the outside of the pin holes.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0017] This invention connects the outer shell and the self-resetting push button switch through a snap-fit ​​structure. Pressing the outer shell moves the button end of the self-resetting push button switch, thus turning the push button switch on or off. The switch position detection circuit board detects the signal changes when the push button switch is on or off, and then sends the corresponding image of the self-resetting push button switch to an OLED display screen for real-time and intuitive display of its working status, thereby enabling the push button switch to display its own status intuitively and conveniently.
