With the development of society, people not only pay attention to the performance of automobiles, but also have higher requirements on automotive interiors, and the automotive interiors are expected to be cool and have more technological sense. The light effect of the automobile is a means for improving the science and technology sense and cool dazzling. For this purpose, leathers of different materials and different light transmission degrees are known, such as polyvinyl chloride (PVC) leathers, thermoplastic polyolefin elastomer (TPO) leathers, Polyurethane (PU) leathers, Thermoplastic Polyurethane (TPU) leathers, etc.
In order to exhibit a more cool lighting effect, the leather interior is required to exhibit a specific pattern when backlit. For example, the light-transmitting leather is generally applied to automobile door trim panels, the leather can penetrate a grid-shaped pattern after a backlight is turned on, in order to realize the penetrated grid shape, the conventional process adopted at present is to carry out pattern design type coating covering on the back of the leather or the back of a framework, the position covered by a coating cannot realize light transmission, and the pattern at the position uncovered by the coating forms a pattern displayed after light transmission. Or the skeleton is hollowed, and the hollowed part forms a pattern after light transmission. The methods have the disadvantages of complicated process and high processing cost, and the mechanical strength of the framework can be influenced by hollowing the framework.
In addition, EP2233366B1 discloses a decorative element comprising a light-impermeable leather layer, on which particles are applied in order to achieve a light-transmitting pattern, so that a grain surface is formed, and the leather layer is at least partially thinned so that the protrusions of the grain surface are light-impermeable and the recesses are light-transmitting, so that the light-transmitting pattern is formed upon backlighting. The method has the advantages of limited pattern complexity and definition and complicated process. Patent document CN207274074U discloses a light-transmitting ornament in which a light-transmitting first leather layer and a light-opaque second leather layer are coated on a light-transmitting base fabric in this order, the second leather layer being partially covered with CO, for example 2 And the optical fiber, the infrared light or the ultraviolet light and the like are removed by laser engraving so as to form the pattern displayed after light transmission. The pattern layer thus formed is easily worn and thus cannot be stably present for a long time.
SUMMERY OF THE UTILITY MODEL
Based on the above technical background, the to-be-solved technical problem of the utility model lies in providing a light-permeable gadget, it can realize with low costs arbitrary design, stable printing opacity pattern. The light-transmitting pattern is understood to be a bright light pattern which can be obviously shown through the ornament when light is irradiated from the back or the side of the leather; the pattern is not revealed on the surface of the trim piece when the light is illuminated from the front or not.
Therefore, the utility model provides a light-permeable decoration piece, which comprises a first leather layer and a second leather layer arranged above the first leather layer, wherein,
the first leather layer is provided with a through notch and a residual part surrounding the notch, the notch can transmit light and form a pattern, and the residual part is not transmitted with light; and is
The second leather layer is semi-transparent, and the surface of the second leather layer is provided with concave-convex patterns, so that the patterns of the notches are invisible when the second leather layer is not irradiated by backlight or sidelight, and the patterns of the notches are displayed on the visible surface of the light-permeable decoration when the second leather layer is irradiated by the backlight or the sidelight.
According to the utility model discloses, first leather layer is made by the material that is opaque to make except the notch part that runs through, the remaining part on first leather layer is opaque. When light is irradiated from the back or side of the first leather layer, light can only partially penetrate through the recesses, thereby obtaining a predetermined light-transmitting pattern.
Meanwhile, the second leather layer covering the first leather layer is made of a semi-transparent material. The second leather layer has a light transmittance of 50% to 60% when a light-colored leather material is used, and has a light transmittance of 20% to 30% when a dark-colored leather material is used. The surface of the second leather layer, particularly the visible surface, has an uneven pattern which can be formed by high-temperature embossing of the second leather layer, or the second leather layer is scraped on a release paper with a pattern to transfer the uneven pattern to the surface of the second leather layer.
The decorative pattern can give the leather pleasing to the eye texture and comfortable feeling, simultaneously, because the semi-transparency nature on second leather layer and the combination of surperficial relief pattern, play the effect of hiding to the first leather layer that is located the below, can shelter from the colour, the notch structure and the possible surface texture on first leather layer. Therefore, the notch and the pattern formed by the notch can not be seen through the visible surface when the decorative part is not irradiated by backlight or sidelight, and the light-transmitting pattern formed by the notch can be shown on the visible surface of the light-transmitting decorative part only when the decorative part is irradiated by the backlight or the sidelight. In addition, since the second leather layer is covered over the pattern layer formed of the first leather layer, the pattern layer is protected from abrasion, so that the light-transmitting pattern can be stably maintained for a long time.

Preferably, the diameter of the particles constituted by the raised portions of the pattern is < 1 mm. The most ideal uniformity of light transmission is thereby achieved.
According to the utility model discloses, the degree of depth distribution of decorative pattern on second leather layer can be even, also can be inhomogeneous. The uniform pattern depth enables uniform light transmission brightness. Uneven pattern depth can then make the decorative pattern have the stereovision as required, and some partial pattern concave-convex difference is great, and the pattern depth is darker, and some partial pattern concave-convex difference is less, and the pattern depth is lighter to lead to when being shaded or the sidelight is shone, the light-transmitting is strong different, and then forms expected printing opacity gradient.
Preferably, the first leather layer and the second leather layer used in the present invention are selected from one or more of polyvinyl chloride (PVC), thermoplastic polyolefin elastomer (TPO), Polyurethane (PU), Thermoplastic Polyurethane (TPU).
The materials of the first leather layer and the second leather layer can be the same or different. For example, the first, opaque leather layer can be a PVC foam layer or a PVC dense layer, and the second, semi-opaque leather layer associated therewith can be a PVC dense layer or a PU skin layer.
In addition to the leather materials mentioned above, other materials can in principle also be used, as long as they conform to the first leather layer, which is opaque, and the second leather layer, which is translucent.
An inner lining layer can be arranged below the first leather layer according to requirements. The lining layer can use base cloth, so that the mechanical support strength of the light-permeable decoration piece is improved, and fabric with smooth cloth grain surface is preferably adopted. The inner liner may also use a sponge to provide better softness.
