Description

Technical Field

[0001] The utility model relates to the technical field of display screens, and in particular to a touch button assembly and a display screen. Background Art

[0002] Touch button components and displays are key parts of the user interface of modern electronic devices. They achieve touch input through capacitive, resistive, infrared or surface acoustic wave technologies, while displays use LCD, OLED, AMOLED, QLED or Micro LED technologies to present images. The integration of these components, such as touch screens, allows users to interact directly with the screen, greatly simplifying device design and providing a more intuitive user experience. With technological advances, these components are developing towards higher performance, lower energy consumption and greater intelligence, driving the innovation of electronic device forms and interaction methods, such as foldable screens and more advanced touch technologies, indicating that future electronic devices will have more diverse and personalized interactive experiences.

[0003] Existing display screens with touch control buttons are usually composed of a screen body, a screen frame, a system control board, a back panel and a touch button assembly. Because the touch button assembly needs to be close to the screen frame to achieve touch control, the existing touch button assembly is generally fixed by small screws and corresponding rods at corresponding positions. When the user needs to inspect and repair the touch button assembly, the user needs to use tools to rotate and remove the small screws, thereby removing the touch button assembly to achieve inspection and repair of the touch button assembly, which reduces the inspection efficiency to a certain extent.

[0004] Therefore, it is necessary to provide a new touch button assembly and display screen to solve the above technical problems. Utility Model Content

The clamping block is used for fixing the touch button assembly.

[0009] Preferably, a rotating hole is provided on one side of the placement frame away from the clamping block. One end of the fixing plate away from the clamping block is fixedly provided with a rotating column. Both sides of the rotating column extend movably into the rotating hole respectively.

[0010] Preferably, a sliding hole is provided on one side of the placement frame adjacent to the clamping block. The outer surface of the clamping block is movably connected to the inside of the sliding hole. The limiting member is movably arranged inside the sliding hole. One end of the limiting member away from the clamping block extends movably out of the placement frame.

[0011] Preferably, the limiting member includes a limiting column and a return spring. The limiting column is movably arranged inside the sliding hole. One end of the limiting column adjacent to the clamping block is fixedly connected to one end of the clamping block. One end of the limiting column away from the clamping block extends movably out of the placement frame. A driving member is fixedly arranged at one end of the limiting column away from the clamping block. The return spring is fixedly arranged inside the sliding hole. One end of the return spring adjacent to the clamping block is fixedly connected.

[0013] Compared with the related art, the touch button assembly and the display screen provided by the present utility model have the following beneficial effects:

[0014] When the user needs to detect and repair the touch button assembly, the user rotates the driving member. The movement of the driving member drives the clamping block to contract towards the inside of the placement frame. The clamping block disengages from the fixing plate. The clamping block releases the limit on the fixing plate. Thus, the fixing plate rotates along a corner of the placement frame. The user can remove the touch button assembly from the placement frame to facilitate the detection and repair of the touch button assembly, which improves the detection and repair efficiency to a certain extent.
