AI Technical Summary
Technical Problem
Existing composite cello back plates often deform and become unbalanced in tone due to a lack of consideration for back plate strength during long-term use. Disassembly is also cumbersome and can easily damage the back plate.
Method used
The backplate structure is reinforced with stiffeners and composite components, and tool-free disassembly is achieved through connecting components. Anti-collision strips protect the corners, and reinforcing fibers and damping layers improve strength and vibration reduction.
Benefits of technology
It improves the structural strength and ease of disassembly of the back panel, prevents deformation and damage, reduces vibration and noise, and simplifies the disassembly process.

Abstract
The utility model discloses a composite material cello backboard, comprising a body, a panel, a reinforcing member and a composite member. The utility model has the beneficial effects that the movable block is driven by the connecting rod to move towards the direction of the positioning groove, so that the locking block is gradually opened by the cambered surface on the outer side of the separating block, the locking block is separated from the inner side of the positioning groove, the connecting block loses the limit, the body is pulled out backwards, and the disassembly can be completed; it can be guaranteed that the back plate is not damaged during disassembly; the structural strength of the backboard is enhanced by arranging the reinforcing ribs, deflection deformation of the backboard can be reduced, structural fatigue or cracking caused by too large vibration amplitude can be avoided, when the cello backboard bears longitudinal tension of strings, the reinforcing fibers can prevent the backboard from tensile deformation, the damping layer can reduce the vibration amplitude of the cello during playing, and the service life of the cello is prolonged. Howling or noise is avoided, the structural strength of the back plate is effectively enhanced, and it is guaranteed that the back plate cannot deform in long-term use.
