Embodiment 1

[0037] A car heat shield such as figure 1 and figure 2 As shown, it includes an upper half cover 1 and a lower half cover 2 fixed to each other. Both the upper half cover 1 and the lower half cover 2 are sheet metal parts. An exhaust channel 3 for penetrating the exhaust pipe is formed between the cover 1 and the lower half cover 2, a large port 4 and a small port 5 are respectively formed at both ends of the exhaust channel 3, and the upper half cover 1 and the lower half cover 2 are connected to each other. A snap ring groove 6 is formed by stamping at the small port 5, and a metal mesh roll 7 for enhancing connection sealing is fixed in the snap ring groove 6. The use of metal mesh to make the seal has the following advantages: First, the material of the metal mesh is similar to that of the upper half cover 1 and the lower half cover 2, so their thermal expansion and contraction properties are also similar, thereby avoiding the small port 5 and the inlet port 5 during use...

Embodiment 2

[0041] A car heat shield such as Figure 4 and Figure 5As shown, the difference from Embodiment 1 is that the metal mesh roll 7 includes two half-ring mesh rolls 8 arranged in the snap ring groove 6, and the half-ring mesh roll 8 is helically wound by a metal mesh. There are perforations in the metal mesh, the semi-ring roll 8 is pierced with a shaped half-ring 9, the two ends of the metal mesh are fixed on the shaped half-ring 9 by spot welding, and the two ends of the shaped half-ring 9 are welded and fixed on the On the inner wall of the snap ring groove 6, the semi-ring net roll 8 is fixed, and the semi-ring structure is adopted to facilitate processing and production.

[0042] In summary:

[0043] When the present invention is used, by adopting the metal mesh roll 7 as the sealing member, firstly, the material of the metal mesh is similar to the thermal expansion and contraction performance of the upper half cover 1 and the lower half cover 2, thereby improving the cla...

Abstract

The invention discloses an automobile heat shield and relates to the field of automobile exhaust systems. The automobile heat shield comprises an upper half shield and a lower half shield which are mutually fixedly connected, wherein an exhaust passage used for penetrating into an exhaust pipe is formed between the upper half shield and the lower half shield, and two ends of the exhaust passage separately form a large port and a small port; and a clamping ring groove is arranged at the small port between the upper half shield and the lower half shield, and a metal mesh coil used for enhancingconnection sealing is fixed in the clamping ring groove. Aiming at the problem that the connection sealing performance of a heat shield is insufficient in the prior art, according to the automobile heat shield, the metal mesh coil is adopted as a sealing member, so that gaps are avoided at a connection position of the heat shield, and the sealing performance is improved; and moreover, the corrosion resistance and the service life of the metal mesh coil are better.

Description

technical field [0001] The invention relates to the field of automobile exhaust system, more specifically, it relates to an automobile heat shield. Background technique [0002] The automobile exhaust system mainly discharges the exhaust gas from the engine, and at the same time reduces the pollution of the exhaust gas and reduces the noise. Automobile exhaust systems are mainly used in light vehicles, mini-cars, passenger cars, motorcycles and other motor vehicles. An automobile exhaust system refers to a system that collects and emits exhaust gas. It generally consists of an exhaust manifold, an exhaust pipe, a catalytic converter and an exhaust temperature sensor. A heat shield for heat insulation is installed on the exhaust pipe. [0003] For the existing heat shield structure, such as the Chinese patent whose patent publication number is CN205445756U, it discloses a kind of automobile exhaust pipe heat shield, which is used to fit and be welded on the outer surface of ...
