Description

Technical Field

[0001] The utility model belongs to the technical field of heat insulation sheets, and particularly relates to a splicable automobile heat insulation sheet. Background Art

[0002] When an automobile engine is working, a large amount of heat will be generated. If it is not isolated, the temperature in the passenger compartment will rise. At the same time, due to being outdoors for a long time under the scorching sun, the temperature in the vehicle is also likely to rise. Therefore, heat insulation sheets are generally installed for heat insulation.

[0003] Automobile heat insulation sheets are generally made by stamping. However, due to different automobile models, the shapes and sizes of applicable heat insulation sheets are also different. When several smaller heat insulation sheets are assembled, gaps will be formed at the joints of the heat insulation sheets, and misaligned bonding is likely to cause an increase in the thickness of the joints of the heat insulation sheets, which is not conducive to the installation of the vehicle top trim panel. While using larger heat insulation sheets for cutting will result in an increase in the use cost of the heat insulation sheets.

[0004] Based on this, a splicable automobile heat insulation sheet assembled by multiple smaller heat insulation sheets is designed. Content of the Utility Model
