Background technique
Usually, mobile terminal device can be divided into catv terminal machine or wireless terminal, as catv terminal machine, typically such as has office to use or home-use desk telephone; As wireless terminal, typically such as there are PCS (person-to-person communication service), mobile phone, PDA (PDA Personal Digital Assistant).Usually, wireless terminal provides portability and mobility to user, therefore, is also referred to as mobile communication terminal or mobile terminal device.
Along with technology is flourishing, mobile terminal device as above has surmounted the simple stage of transmitting acoustic information, can provide Word message, image information, game etc. to user, its kind is roughly divided into board-type (bartype), has the turning-lid type of lid (flip type) and folded form (folder type).
Due to when folding mobile terminal facility have a call or the time of carrying can folded formation (folder) structure of folding, therefore the problem of the length length existed in board-type, turning-lid type is solved, but, the problem that the hinge fraction that its existence connects upper folded formation and lower folded formation is easily impaired.
In order to solve the problem of this folding mobile terminal machine, proposing and making lid relative to the lid sliding type portable terminal machine of body along the semi-automatic folding of slide anteroposterior.For this reason, described lid sliding type portable terminal machine needs the hinge component that lid is combined slidably relative to the body of mobile terminal device, and described hinge component must possess the spring providing elastic force in order to carry out semi-automatic folding action.Below, the spring of the lid sliding type portable terminal machine based on prior art is described.
Fig. 1 and Fig. 2 is the reference figure of the spring for illustration of the lid sliding type portable terminal machine hinge component based on prior art.
Fig. 1 represents the initial configuration of the spring being arranged on lid sliding type portable terminal machine hinge component, and this spring is the torque spring 50 with the spring section 51 spirally reeled.
Described torque spring 50 is configured to the wire rod 51 continuous reeling curl of a circular cross section, and its one end and the other end are formed as supporting portion 52, and this supporting portion 52 is wound into circle and can by rivet support.Traditional torque spring 50 like this can only use a wire rod 51 on manufacturing with the circular cross section of advantage to make, and owing to not needing the joint between punching press and wire rod completely, therefore has the advantage that manufacturing expense is low.
But, because described torque spring 50 is formed as two-layer by the wire rod 51 reeled, therefore cause thickness to increase, and, in nearest Long travel type mobile terminal device, provide enough elastic force aspects to be restricted.In order to overcome the narrow limitation of aforesaid torque spring 50, also once attempted to form the structure two torque springs 50 being configured at a hinge component, but, there is the problem that installation space is increased in this structure, in the Long travel type mobile terminal device that the folding length of lid is long, particularly still there is the problem of the elastic force that can not provide enough.
So, in order to improve the above-mentioned shortcoming of torque spring 50, developing and using the laminated spring 60 formed by sheet elements 61 lamination of multiple arc-shaped as shown in Figure 2 recently.In this laminated spring 60, except centered by support ring 63 winding one end and the other end supporting portion 62 except, other parts are separated from each other.
Because this laminated spring 60 be made up of multiple sheet material 61 provides stronger elastic force compared to torque spring 50, therefore, not only reliably carry out the opening and closing movement of the lid of mobile terminal device, and be applicable to being applied to Long travel type mobile terminal device.
But, from enlarged view, based in the laminated spring 60 of prior art, owing to needing to utilize laser bonding 64 to engage by after the supporting portion 62 of one end of sheet material and the other end closely lamination, therefore, in order to easily carry out laser bonding 64, do not adopt the wire rod of the circular cross section of low cost of manufacture, and adopt the sheet material 61 of the square cross-section produced by drawing procedure or calendering procedure.Thus, there is the shortcoming that spring cost proportion rises in hinge component.And, guaranteeing at least to adopt three sheet materials 61 could provide enough elastic force in Long travel type mobile terminal device when adopting laminated spring 60, therefore, having increased the weight of the pressure of cost.
