Below application example of the present invention as follows.
A kind of spring hinge of slide cover type terminal phone is provided, become curved to a direction elasticity when sliding for slippery cover plate, by excellent type spring wire warpage is that the plural arc spring wire rod (10) of arc is formed, above-mentioned plural arc spring wire rod (10) is to the combination of warpage direction, the curvature difference of above-mentioned each arc spring wire rod (10) to the combination of warpage direction, make mid portion depart from mutually to the warpage direction, in the curvature of arc spring wire rod (10), be positioned at the most inboard arc spring wire rod (10) of warpage direction and form minimum curvature, offside in outermost arc spring wire rod (10), form maximum curvature more, each two ends of plural arc spring wire rod (10) combine formation by the hinge of hinge combination with slippery cover plate and fixed head, thereby the present invention is applied to the sliding block of terminal phone as shown in figure 12, during the sliding action of terminal phone, the arc spring wire rod (10) that departs from mutually and constitute spring hinge provides suitable elastic force, makes that the sliding action of slippery cover plate is mild and roundabout.
Also have, direction outermost arc spring wire rod (10) length (L) that arc spring wire rod (10) is opposite from the most inboard arc spring wire of warpage direction (10) to warpage is more and more longer as shown in Figure 1, relatively rise with inboard arc spring wire (10), the less outer arcuate spring wire (10) of tortuous deformation amount is preparing tortuous deformation in assembling process, thereby the tortuous deformation amount of whole arc spring wire rod (10) can be evenly, when so assembling under the situation of different length, the length of in fact the most inboard arc spring wire (10) can be elongated, when but spring hinge is assembled in sliding block, possessing the approaching assembled length of the physical length of following under the situation that the most inboard arc spring wire has assembled in assembling under the situation that warpage improves.
And, as shown in Figures 2 and 3, by resilient bias according to spring wire thickness, section factor or material difference, more the most inboard, the elasticity of arc spring wire rod (10) is just more little, and therefore, the most inboard arc spring wire (10) warpage that the tortuous deformation amount is many becomes mild and roundabout, the elasticity of outermost arc bullet yellow line material (10) is replenished the most inboard arc spring wire (10) elasticity and during the sliding action of sliding block, is realized mild and roundabout slip by mutual organic action.
And, as Fig. 4,5 and shown in Figure 6, when thickness, section factor or the curvature variant part (13) of elasticity by spring wire that tortuous deformation concentrates on the mid portion of arc spring wire rod increases, the elasticity of the mid portion of the arc spring wire rod that tortuous deformation is many can increase and tortuous deformation can divide to the less both sides of elasticity and leaves, it is uniform tortuous deformation all over that the result becomes, and can improve the durability of arc spring wire rod.
And, shown in Fig. 7,8, above-mentioned arc spring wire rod (10) forms buffering joggling part (12) at mid portion, making that elasticity can be divided in the tortuous deformation process leaves, the elasticity of the mid portion of the arc spring wire rod that elasticity can be concentrated can leave by branch by buffering joggling part (12), thereby when the sliding action of sliding block, can realize mild and roundabout slip, also can improve the durability of arc spring wire rod.
Application on the industry
Therefore, the present invention is made up of the plural arc spring wire rod to the warpage deviation in driction, thereby the thickness attenuation of spring hinge can embody ultra-thinization of terminal phone.
Also have, above-mentioned plural arc spring wire rod respectively bend the curvature difference, the suitable elastic force of corresponding slippery cover plate sliding position is provided, make that the sliding action of slippery cover plate is mild and roundabout, can design various such sliding action characteristics according to designer's intention.
