Description

Interior material with reinforced tensile force in the morphing area and morphing surface structure to which it is applied}

The present invention relates to an interior material component in which the tensile force of a morphing region is reinforced and a morphing surface structure to which the same is applied. More particularly, when a switch for operating various devices mounted on a vehicle is applied in a morphing method, the tensile force to the protruding region of the morphing switch is strengthened. It relates to an interior material component that improves product life by preventing switch marks or sagging on the skin by applying a member, and a morphing surface structure to which it is applied.

Various switches for operating driving-related devices or devices for providing various conveniences may be provided in the vehicle.

Conventionally, a push button type mechanical switch has been applied, but with the development of technology, a touch type or light sensing type electronic switch is also applied.

In such a switch structure, an empty space or a gap may be formed in the connection portion and the contact portion between the components, so that foreign substances may be introduced into the switch structure. When a foreign substance is introduced into the switch structure, a problem occurs in the operation of the switch, and in the case of an electronic switch, a problem occurs in that the electronic switch itself is damaged according to the inflow of foreign substances such as liquid.

Furthermore, the switch structures are exposed to the outside and become an element that hinders the design aesthetics of the interior of the vehicle. In particular, in recent years, with the trend of pursuing a minimalist life, an atmosphere is being created that is reluctant to reveal complex switch structures on the exterior.

Technologies for applying morphing switches to vehicles have been proposed in recent years to solve various problems of the switch structure and keep pace with changes in social atmosphere.

In the morphing switch, the switch structure is not exposed on the skin surface in normal times, but the switch structure pops up by pushing up the skin in a situation where a switch operation is required.

The pop-up operation of the morphing switch applies an external force to the vehicle interior skin, and as the pop-up operation is repeated, stress is accumulated on the skin, resulting in a problem that the switch marks remain on the skin surface after a certain period of time has elapsed.

In particular, according to the pop-up operation of the morphing switch, an external force is concentrated on the skin region corresponding to the outer portion of the switch, so that the skin region is stretched and sagged.

The disadvantage of applying such a morphing switch is that the skin is permanently deformed, which leads to a problem of having to replace the entire interior material of the vehicle to which the morphing switch is applied.

That is, in the tensile force control portion 110a of the skin member 110 , the lower surface 112 has a curved shape, and thus the thicknesses T11 , T12 , and T13 gradually become thinner from the outermost portion to the center portion. In addition, the thicknesses T13 and T14 may be constantly maintained while moving to the holding portion 110b of the skin member 110 .

The tensile force adjusting portion 110a and the holding portion 110b of the skin member 110 may be deformed into various shapes to correspond to the shape of the morphing switch.

The functional means 120 includes a plurality of concave portions 121 concavely recessed inwardly on the lower surface of the skin member 110 , and the concave portions 121 are deformed downward as the upper surface of the skin member 110 is pressed. Functionality such as cushioning can be imparted by absorbing the external force that is applied while being pressed.

In addition, the functional means 120 may include a plurality of support legs 125 and a plurality of cavity spaces 123 .

The support leg 125 forms a part of the concave portion 121 and is formed between adjacent concave portions 121 to support the concave portion 121 . That is, when the skin member 110 is pressed, the concave portion 121 may be deformed toward the lower cavity space 123 while receiving the support of the support leg 125 .

When the plurality of concave portions 121 are arranged in a uniform pattern, each side of the support leg 125 may be formed to have the same shape as each other. Alternatively, when the plurality of concave portions 121 are randomly distributed and arranged, the support legs 125 may be deformed into various shapes to correspond to the side surfaces of the adjacent concave portions 121 .

The support leg 125 may be formed such that its cross-sectional area is gradually reduced from the top to the bottom to correspond to the shape of the side surface of the concave portion 121 . That is, the support leg 125 is not bent and deformed in a specific direction when the bending direction is not set. Due to the shape of the support leg 125 , even when the skin member 110 is pressed, the support leg 125 is not deformed and can support the concave portion 121 while maintaining its shape.

The cavity space 125 may be provided between the inside of the concave portion 121 and the substrate 150 . The shape and size of the cavity space 125 may be changed according to the shape of the recess 121 and the support leg 125 .

The substrate 150 may be in contact with the lower surface of the skin member 110 to support the skin member 110 . The base material 150 may be formed in various shapes to correspond to the shape of the part where the interior parts are mounted. For example, in the case of an interior material part applied to an armrest of a vehicle, the base material 150 may be provided to correspond to the shape of the armrest, and in the case of an interior material part applied to a door trim, the base material 150 may be provided to correspond to the shape of the door trim. ) can be provided.

Also, the shape of the skin member 110 may be deformed according to the shape of the substrate 150 . That is, as the skin member 110 is installed in contact with the base material 150 , the shape of the skin member 110 is changed to correspond to the shape of the base material 150 , and the skin member 110 is formed by the base material 150 .

The support leg 125 of the functional means 120 is positioned in contact with the cushioning member 130, and since the support leg 125 itself does not deform when the skin member 110 is pressed, the support leg 135 according to the external force applied. As the buffer member 130 is deformed by pushing the buffer member 130 downward, an external force applied to the support leg 125 may be absorbed by the buffer member 130 .

That is, when the skin member 110 is pressed, the concave portion 121 may be deformed toward the cavity space 123 below while being supported by the support leg 125 , and the support leg 125 itself is bent and deformed. Since it does not, the buffer member 130 is deformed.

As described above, as the concave portion 121 is deformed toward the lower cavity space 123 according to the pressure of the skin member 110 , external force can be absorbed primarily, and the support leg 125 is formed by the buffer member 130 . As external force is absorbed secondarily while deforming by pushing downward, functionality such as cushioning can be further improved.
