However, the above-mentioned various structures all provide the required driving force by simple coil springs or wire-shaped torsion elastic components, so that they can be applied to small electronic devices such as mobile phones, handheld game consoles or personal digital assistants (PDAs). When it comes to products, due to the small size and light weight of the slide cover, it can indeed achieve the practicability of easy use. However, when it is applied to larger electronic products such as portable computers or tablet computers, the weight of its moving mechanism increases, and Its moving distance is also increased, which is bound to increase the elastic force of the elastic driving component and its elastic action stroke. In this way, when the sliding cover slides to the end of the opening or closing stroke, a larger impact will be generated at the same time, which is easy to cause each zero. Damage to the components. At the same time, if a unilateral push force is applied during operation, it is easy to cause the deflection of some mechanisms and affect the smooth sliding of the moving mechanism. In severe cases, it may even cause jamming and inability to move. .
