Abstract

The invention relates to an installation structure of an aluminum heat shield, which comprises an aluminum heat shield and a support member. The aluminum heat shield is provided with an installation part, the installation part is provided with a first connection hole, and the support member is provided with a second connection hole. hole; also includes an expansion sleeve and an expansion nail, the expansion sleeve is provided with a central hole in the axial direction, and the expansion sleeve includes a compression section, a first step surface, a first connecting section, and a second step surface arranged in sequence from the top end to the bottom end and the second connecting section, the radial dimension of the pressing section is greater than the radial dimension of the first connecting section, and the radial dimension of the first connecting section is greater than the radial dimension of the second connecting section; the first connecting section and the first connecting hole Cooperate, the second connecting section is matched with the second connecting hole, the first stepped surface is supported on the installation part, and the second stepped surface is supported on the supporting member; the expansion nail is interference-fitted with the central hole. The invention can reduce or even eliminate the deformation caused by the installation structure by rationally setting the installation structure of the aluminum heat shield, and can reliably fix and install the aluminum heat shield.

Description

technical field [0001] The invention relates to automobiles, in particular to an installation structure of an aluminum heat shield. Background technique [0002] A heat shield is a common part of an automobile, and the heat shield is used to block heat. The existing heat shield is generally fixed and installed in the car by bolts. Existing heat shields are generally made of heat insulating materials and / or steel, and based on the lightweight requirements of vehicles, it is necessary to use heat shields made of aluminum materials instead. However, the heat shield made of aluminum is prone to deformation. If bolts are used to fix the heat shield made of aluminum, when the bolts are tightened, the heat shield made of aluminum will deform or even break, which is not reliable. Secure the heat shield. Contents of the invention [0003] The object of the present invention is to provide a mounting structure for an aluminum heat shield, which can reliably and securely install the...
