A car variable tail throat

Abstract

The invention discloses a variable exhaust pipe sleeve of an automobile. The variable exhaust pipe sleeve comprises a gas inlet pipe, a shell, a main support, an LED lamp, a direct-current motor, a motor support, blade supports, a screw ring assembly, a steel wire circular ring, connecting sheets, a screw ring, a screw rod and blades. The gas inlet pipe is mounted at an end of the shell, the main support is mounted inside the shell, the LED lamp is mounted at one end of the main support, the direct-current motor is mounted on the motor support, the motor support is mounted in the middle of the other end of the main support, one end of each blade support is mounted on the outer side of the other end of the main support, the screw rod is mounted on a rotary shaft of the direct-current motor, one end of each connecting sheet is serially connected with one end of the corresponding connecting sheet by the steel wire circular ring, the steel wire circular ring and the connecting sheets are integrally mounted between the screw ring assembly and the screw ring to be mounted on the screw rod, and each blade is movably connected with the other end of the corresponding blade support and the other end of the corresponding connecting sheet. The variable exhaust pipe sleeve has the advantages that waste gas can be assuredly smoothly exhausted; exhaust back pressures can be increased, and loss of torque can be prevented; the variable exhaust pipe sleeve is provided with the LED lamp, accordingly, the driving safety can be improved, and tailgating can be prevented.

Description

technical field [0001] The invention relates to the related technical field of automobile exhaust pipes, in particular to an automobile variable tail throat. Background technique [0002] Tail throat is also called automobile tail throat, which is a component installed on the original exhaust tail. The tailpipe of the car muffler is used to decorate the tailpipe of the exhaust pipe. In addition to preventing the deformation of the tailpipe of the car, it also plays the role of supercharging and turbulence. It can also make the sound of the exhaust pipe slightly soft and pleasant to a certain extent, reducing noise. But the reason why many car owners buy it is because it has a strong decorative effect. [0003] Depending on the type of tail throat, there are several actual functions: 1. There are special tail throats for fire safety, such as those used on tank trucks and some special vehicles; 2. Purely aesthetic, there are many chrome-plated ones. The tail throat is fixed...

AI Technical Summary

Problems solved by technology

[0004] The tail throat of the car is installed on the exhaust pipe at the rear of the car. The existing tail throat of the car is fixed. Therefore, when the engine speed increases during the driving process of the car, the exhaust volume also increases, which is not conducive to exhaust gas. exhaust; when the car engine speed is low, the exhaust volume is small, and the exhaust back pressure cannot be changed, resulting in loss of torque
