Description

Technical Field

[0001] This utility model relates to the field of improved remote control technology with display screen, specifically to a remote control with screen that has anti-drop and screen breakage function. Background Technology

[0002] Traditional remote controls with displays suffer from screen breakage due to drops. Conventional designs can only withstand drops from 1 meter, and even then, 100% protection isn't guaranteed. Drops from 1.2 or 1.5 meters are even more challenging and require foam or soft rubber for protection, yet screen breakage remains a concern. Traditional technologies require additional materials, manpower, and advanced assembly techniques, which no longer meet product quality requirements. Furthermore, the use of foam and soft rubber increases assembly difficulty and production costs, and provides poor protection for the display screen, resulting in relatively low practicality. Therefore, this paper proposes a remote control with a drop-proof screen protection function to address these issues. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a screen-mounted remote control with anti-drop and screen-shattering function. It utilizes a physical support structure to achieve anti-shattering protection for the internal display screen of the remote control, raising the screen-shattering protection requirement of the remote control to a height standard of 1.5-2 meters. No additional materials are required, saving labor and material costs, and the assembly difficulty is relatively low.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it comprises a screen lens 1, a front shell 2, a liquid crystal screen 3, conductive strips 4, a backlight plate 5, a PCBA main board 6, a bottom shell 8, a bracket 16, limiting and fixing ribs 17, a supporting boss 18, a fixing groove 19, and a mounting and fixing boss 20; the screen lens 1 is embedded and installed on the front shell 2, the liquid crystal screen 3 is installed inside the front shell 2 at the position corresponding to the screen lens 1, the backlight plate 5 presses the two conductive strips 4 onto the back of the liquid crystal screen 3, and the bottom shell 8 presses the PCBA main board 6 onto the front shell 2. Inside, the backlight panel 5 has four brackets 16 on its side, and the inner edge of the bottom shell 8 has multiple limiting and fixing ribs 17. The bottom shell 8 also has support protrusions 18 with the same number and corresponding positions as the brackets 16. Each bracket 16 is supported and installed by the corresponding support protrusions 18. The limiting and fixing ribs 17 snap the backlight panel 5 into the bottom shell 8. The bottom shell 8 has a fixing groove 19 on its edge. The front shell 2 uses the mounting and fixing protrusions 20 on its edge to insert into the fixing groove 19 to install and fix the LCD screen 3, the backlight panel 5 and the PCBA motherboard 6.

[0005] Furthermore, the front shell 2 and the bottom shell 8 are fixedly installed by interference fit of the integrally formed support boss 18 and fixing groove 19.

[0006] Furthermore, the PCBA motherboard 6 is screwed and fixed to the internal cavity formed by the front shell 2 and the bottom shell 8 by motherboard screws 7.

[0007] Furthermore, a silicone button 15 is installed on the inner side of the lower part of the faceplate 2. The silicone button 15 is connected to the PCBA mainboard 6 by contact between the negative spring 11, the connecting spring 12, the positive spring 13 and the dome 14.

[0008] Furthermore, a battery 10 is installed inside the bottom shell 8, and the battery 10 is installed on the lower part of the bottom shell 8 by a battery cover 9.

[0009] The working principle of this utility model is to transfer the force generated by the drop to avoid damage to the display screen. When the drop occurs, the external force hits the remote control shell, and the shell transmits the force to the PCBA motherboard. The PCBA motherboard then transmits the force to the bracket on the side of the backlight board. The bracket transmits the force to the overall shell through the limiting and fixing ribs on the bottom shell, thus forming an external force circulation that does not damage the internal LCD screen.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are as follows: it solves the problem of screen breakage when a remote control with a screen is dropped, eliminates the need for materials such as foam and soft rubber for screen protection, and uses a physical support structure to protect the internal display screen of the remote control from breakage. It can raise the screen protection requirement of the remote control to a height standard of 2 meters without the need for additional materials, saving labor and material costs. It is also easier to assemble, has relatively high practicality, and is suitable for widespread use. Attached Figure Description
