Description

Technical Field

[0001] This utility model relates to the field of LED digital display technology, and in particular to a display switching device that combines a knob and a button. Background Technology

[0002] The display switching device is a multi-functional control device that integrates knob rotation and button pressing operations. It is used in various scenarios that require switching display content or adjusting display parameters, such as smart home control panels, industrial control instrument panels, and display adjustment components of electronic equipment. The rotation of the knob realizes the switching of display content or continuous adjustment of parameters, and the pressing of the button realizes the quick switching of specific display modes.

[0003] Traditional display switching devices consist of a knob body, button assembly, base, and internal transmission structure. In use, users rotate the knob body to switch between different display interfaces or adjust display parameters, and press the button assembly located next to the knob to switch display modes. However, it has obvious drawbacks. Since the button assembly and the knob body are set independently, they not only occupy a lot of space, making the overall structure of the device less compact, but also require users to frequently switch between the knob and the button during operation, affecting the continuity and convenience of operation.

[0004] To address the aforementioned issues, existing technologies attempt to integrate buttons into the vicinity of the knob structure to reduce device size and improve ease of operation. However, in practical use, since existing encoders are knob-type structures, adding buttons in the middle or near the knob causes motion interference between the knob rotation and button pressing. This is because the rotation trajectory of the knob and the pressing stroke of the button overlap or intersect in space, causing them to affect each other during operation and preventing normal operation. Therefore, the buttons can only be placed in other positions on the knob, failing to fundamentally solve the motion interference problem between the knob rotation and button pressing. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a display switching device that combines a knob and a button, aiming to improve the problem of motion interference between knob rotation and button pressing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a display switching device combining a knob and a button, comprising a chassis, an installation mechanism provided on the outside of the chassis, a rotating block provided on the front side of the chassis, and a button mechanism provided inside the rotating block;

[0007] The button mechanism includes a mounting bracket disposed inside the rotating block. Multiple sliders are fixedly connected to the outer wall of the mounting bracket. Multiple sliding grooves are provided on the inner wall of the chassis. The multiple sliding grooves are slidably connected to the corresponding multiple sliders. Multiple threaded holes are provided on the front side of the mounting bracket. Two mounting slots are provided on the front side of the inner wall of the mounting bracket. Buttons are slidably connected to the inner walls of the two mounting slots.

[0008] As a further description of the above technical solution:

[0009] The mounting mechanism includes a bottom ring, which is slidably connected to the outside of the chassis. The outer wall of the chassis has multiple slots 1 around its perimeter. The inner walls of the multiple slots 1 each have two annular grooves on their left and right sides. The outer walls of the bottom ring are rotatably connected to buckles. The inner walls of the multiple slots 1 each have fixed blocks 1. The outer sides of the multiple buckles each have slots 2, which engage with the corresponding blocks 1.

[0010] As a further description of the above technical solution:

[0011] The bottom of the chassis has an installation port, and a connector is fixedly connected to the inner wall of the installation port.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the bottom ring is fixedly connected to the left and right sides with claws, and the rear end of the chassis is fixedly connected to the left and right sides with two rubber pads.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the rotating block has multiple auxiliary openings on its front side, and the surfaces of the multiple auxiliary openings are all treated with anti-slip treatment.

[0016] As a further description of the above technical solution:

[0017] The chassis has two locating pins on both the upper and lower rear sides, and the front side of the outer wall of the two locating pins is rounded.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the chassis is provided with multiple slots 3, and the inner wall of each of the multiple slots 3 is provided with a block 2.

[0020] As a further description of the above technical solution:

[0021] The chassis has a rotating groove on its front side, and the rotating block is rotatably connected to the rotating groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the slider of the mounting bracket engages with the inner wall groove of the chassis to ensure that the rotating block does not affect the internal structure when it rotates. The mounting groove of the mounting bracket is slidably connected to the button to realize the switching of display mode. This structural design of the button mechanism integrates the button inside the rotating block, which solves the problem of interference between the existing encoder knob and button and the need to add buttons in other positions, thus improving the integration and practicality of the device.

[0024] 2. In this utility model, the buckle on the outside of the bottom ring engages with the slot 1 of the chassis. The annular grooves on the left and right sides of the slot 1 provide engagement gaps for the buckle. The slot 2 of the buckle engages with the locking block 1 on the inner wall of the slot 1, so that the buckle is firmly locked on the slot 1, thereby making the bottom ring stably fixed on the outer wall of the chassis. This solves the problem of unstable installation in the prior art and improves the overall reliability and stability of the device installation. Attached Figure Description
