Problems solved by technology

The disadvantage is that the process of alignment is increased in the composite stage, and there is a risk of misalignment
[0010] In addition, for the weakening of the epidermis, the cold knife can improve the appearance compared to the laser, but it still cannot completely solve the problem of visible weakening lines, especially after high temperature exposure, the epidermis shrinks, and the weakening lines will become more obvious
[0011] Therefore, whether it is the overall weakening method or the step-by-step weakening method, there is a defect that the weakening line is visible

Embodiment Construction

[0032] The technical solution of the vehicle leather instrument panel and its weakening processing method proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] see figure 1 As shown, the vehicle leather instrument panel provided according to one embodiment of the present invention includes a skin layer, an intermediate layer 20 and a skeleton layer 30 arranged sequentially from top to bottom, wherein the skin layer includes a cortical layer 10 and a support layer 12 .

[0034] Further, the thickness of the cortical layer is 0.3mm-0.7mm, and the preferred solution adopted in one embodiment is 0.4mm-0.6mm. Its constituent material can be genuine leather or artificial leather, without limitation. The supporting layer has a thickness of 0.4 mm to 0.6 mm and is made of soft fabric material. The overall thickness of the epidermis is 1.0 mm to 1.2 mm.

[0035] According to the vehicle le...

Abstract

The invention discloses a vehicle leather instrument board and a weakening machining method thereof. The vehicle leather instrument board comprises a surface skin layer, an intermediate layer and a framework layer, all of which are sequentially arranged from top to bottom. The surface skin layer comprises a leather layer and a supporting layer. The thickness of the leather layer ranges from 0.3 mmto 0.7 mm. By the adoption of the provided vehicle leather instrument board, the requirement for the airbag bursting safety performance can be met, and meanwhile, the impression and the perceived quality of the surface skin layer on the surface of the instrument board are good and cannot be affected by a weakening line problem.

Description

technical field [0001] The invention relates to the field of manufacturing automotive interior parts, in particular to a vehicle leather instrument panel and a weakening processing method thereof. Background technique [0002] Mid-to-high-end models generally use soft dashboards. The structure of the soft instrument panel generally includes three layers: the skeleton layer, the middle layer and the skin layer. Wherein, the skeleton layer is an injection molded part, and the middle layer generally uses PU foam or elastic fabric, which is mainly used to increase the soft touch; and the skin layer is generally divided into cortical materials such as genuine leather or artificial leather, mainly for To meet the appearance requirements of styling, leather is generally used in luxury models. [0003] Since the airbag on the passenger side is generally arranged under the instrument panel, the instrument panel usually needs to be weakened in the airbag area to ensure the performan...
