Abstract
The invention discloses a soft and hard combined plate structure and aims at providing the soft and hard combined plate structure, which can avoid the fracture of a soft plate when pressing the soft plate and hard plates. The soft and hard combined plate structure comprises the soft plate (1) arranged on the inner side and the hard plates (2) arranged on the front side and the back side of the soft plate (1), and the joint heights of the hard plates (2) on the front side and the back side of the soft plate (1) with the soft plate (1) are different. The difference between the joint heights of the hard plates (2) on the front side and the back side of the soft plate (1) is set to be not less than 0.5mm. The soft and hard combined plate structure can be widely applied in the field of design of soft and hard combined plates in electronic equipment.
Description
Technical field
The present invention relates to a kind of Rigid Flex and avoid the structure of soft board fracture.
Background technology
Rigid Flex is taken into account hardboard two-sided be provided with device, preferably rigidity, satisfy the thickness of structural requirement, also taken into account the advantage of soft board bending at random.Rigid Flex is more and more widely used on electronic equipment.At present, Rigid Flex structurally all be adopt soft board at internal layer, hardboard in outer field version.Generally be to carry out the soft board that is in internal layer earlier during production, press together with hardboard again do not have the zone of hardboard, need earlier hardboard to be cut, perhaps punch out lines and in follow-up operation, remove unnecessary hardboard again.As shown in Figure 1, under regular situation because up and down the section setting of two-layer hardboard 3 is concordant, in the production process during pressing under powerful pressure effect, the soft board 4 of rigid-flex transition position is easy to be squeezed, and has very big stress.This extruding may show as soft board and be extruded to such an extent that broken string occurs, and perhaps soft board does not have bad performance in the short time, but in follow-up final assembly, even broken string appears in consumer's use, cause the situation of machine failure.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of Rigid Flex structure of avoiding the soft board fracture when the pressing rigid-flex is provided.
The technical solution adopted in the present invention is: the present invention includes the hardboard that is arranged on inboard soft board, is arranged on the positive and negative both sides of described soft board, the hardboard of the positive and negative both sides of described soft board is highly different with the applying of described soft board.
The applying difference in height setting of the hardboard of the positive and negative both sides of described soft board is not less than 0.5mm.
The invention has the beneficial effects as follows: because the height that the present invention fits the hardboard of the positive and negative both sides of described soft board and described soft board is provided with different, so, the design of staggering of the soft or hard transitional region of the present invention during described soft board obverse and reverse and hardboard pressing, this has just been avoided causing stress concentrations on described soft board, guaranteed that product can not guarantee the service life of product at soft or hard transitional region broken string in production with in by consumer's use.
Description of drawings
Fig. 1 be in the prior art rigid-flex in conjunction with the schematic diagram of situation;
Fig. 2 be among the present invention rigid-flex in conjunction with the schematic diagram of situation.
The specific embodiment
As shown in Figure 2, the present invention includes the hardboard 2 that is arranged on inboard soft board 1, is arranged on described soft board 1 positive and negative both sides, the hardboard 2 of described soft board 1 positive and negative both sides is highly different with the applying of described soft board 1.As required, the applying difference in height of the hardboard 2 of described soft board 1 positive and negative both sides is provided with than less than 0.5mm.
The present invention is provided with different by the height that the hardboard 2 of described soft board 1 positive and negative both sides and described soft board 1 are fitted, utilize the difference of this applying height to make rigid-flex when pressing, soft or hard transitional region on described soft board 1 obverse and reverse staggers, avoid on described soft board 1, producing stress and concentrated and cause described soft board 1 to occur breaking, thereby guaranteed the quality of product and the service life of product.
In sum, the present invention can be widely used in the Rigid Flex design field in the electronic equipment.
Claims (2)
1. a Rigid Flex is avoided the structure of soft board fracture, comprise the hardboard (2) that is arranged on inboard soft board (1), is arranged on the positive and negative both sides of described soft board (1), it is characterized in that: the hardboard (2) of the positive and negative both sides of described soft board (1) is highly different with the applying of described soft board (1).
2. a kind of Rigid Flex according to claim 1 is avoided the structure of soft board fracture, and it is characterized in that: the applying difference in height setting of the hardboard (2) of the positive and negative both sides of described soft board (1) is not less than 0.5mm.
