A paint-free room door with sound insulation structure

By using a design that alternates between double-sided paint-free panels and multi-layered aluminum honeycomb solid wood boards in the door, combined with sound insulation cotton and a keel structure, the problem of widening door gaps and insufficient sound insulation caused by temperature and humidity changes in traditional paint-free doors is solved, achieving better sound insulation and stability.

AI Technical Summary

Technical Problem

Traditional paint-free soundproof doors are prone to widening of door gaps and decreased sealing performance due to changes in temperature and humidity and uneven stress during long-term use. They also have limited sound insulation effects and cannot meet the needs of high-end venues for quiet spaces.

Method used

It adopts a double-sided paint-free panel finish, and the interior is filled with alternating layers of aluminum honeycomb solid wood boards. Combined with sound insulation cotton and keel design, the sound insulation effect and stability are improved through sound wave inlet and outlet and sound-absorbing protrusion structure.

Benefits of technology

It improves the sound insulation and stability of the door, solves the problem of reduced sealing caused by widening door gaps, and enhances the sound insulation effect.

Abstract

This utility model relates to the field of furniture, specifically disclosing a paint-free door with a soundproof structure. The door includes a door panel with an internal frame. Honeycomb aluminum panels are installed on both sides of the frame, and sound-absorbing cotton is installed on the front and back sides of the honeycomb aluminum panels. One side of the honeycomb aluminum panels and sound-absorbing cotton also has a multi-layer board, and the other side has a second multi-layer board. A decorative layer is installed on the front and back sides of the frame, sound-absorbing cotton, and multi-layer boards. This utility model, by using a double-sided paint-free panel decorative layer and an alternating layering process of aluminum honeycomb multi-layer solid wood boards inside, along with a multi-layer solid wood frame and sound-absorbing cotton added at the intervals between the decorative layer and the aluminum honeycomb, better solves the problem of balanced stress after double-sided gluing, increasing both sound insulation and door stability. The frame design, with its sound wave inlets and outlets, allows sound waves to propagate through the frame to the sound-absorbing protrusions for sound absorption, further enhancing the door's sound insulation capabilities.
