The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] See also Figure 1-Figure 2, which is a schematic diagram of an exhaust tail pipe installation structure of a chemical vehicle proposed in one embodiment of the present invention, the exhaust tail pipe installation structure of the chemical vehicle includes a chassis mechanism 100, and an exhaust mechanism 200 disposed on the chassis mechanism 100, wherein:

[0029] In order to provide support for the exhaust mechanism 200, the chassis mechanism 100 includes a longitudinal beam assembly 110 and a cross beam assembly 120 disposed between the longitudinal beam assemblies 110, wherein the cross beam assembly 120 divides the space enclosed by the longitudinal beam assembly 110 into a first installation area, a second installation area, and a third installation area. The longitudinal beam assembly 110 includes a first longitudinal beam 111 and a second longitudinal beam 112 disposed in parallel, and the cross beam assembly 120 includes a first cross beam 121, a second cross beam 122, and a third cross beam 123 disposed in parallel, wherein the first cross beam 121, the second cross beam 122, and the third cross beam 123 are all disposed perpendicularly to the first longitudinal beam 111 and the second longitudinal beam 112.

[0030] It should be emphasized that the first longitudinal beam 111, the second longitudinal beam 112, and the first cross beam 121 enclose the first installation area; the first longitudinal beam 111, the second longitudinal beam 112, the first cross beam 121, and the third cross beam 123 enclose the second installation area; the first longitudinal beam 111, the second longitudinal beam 112, and the third cross beam 123 enclose the third installation area. The first installation area is used to install the engine, the exhaust mechanism 200 is installed in the second installation area, and the third installation area is used to install the cargo box. It is worth mentioning that the second installation area is located on the lower right side of the cab, cleverly avoiding the fuel pipe, brake oil pipe, steering oil pipe and other oil pipes to avoid the phenomenon of oil leakage causing spontaneous combustion.

[0031] Furthermore, the exhaust mechanism 200 includes a muffler assembly 210, and an exhaust pipe assembly 220 for the muffler assembly 210 and the engine. The exhaust pipe assembly 220 includes a first pipe section 221 for connecting to the engine, a second pipe section 222 connected to the third cross beam 123, a third pipe section 223 connected to the second longitudinal beam 112, and a fourth pipe section 224 for exhausting exhaust gas. The muffler assembly 210 is arranged between the first pipe section 221 and the second pipe section 222. The first pipe section 221 is mounted on the second cross beam 122 and fixedly connected to the adjacent second longitudinal beam 112 through a connecting member. The second pipe section 222 is twisted at an angle of 180°. The third pipe section 223 and the fourth pipe section 224 are both fixedly connected to the second longitudinal beam 112. In addition, the third pipe section 223 is bent into a trapezoidal shape toward the side close to the muffler assembly 210, and the fourth pipe section 224 is also bent 180° toward the direction away from the first installation area, so that the exhaust pipe opening is aligned with the rear of the vehicle.

[0032] The muffler assembly 210 includes a front muffler 211 connected to the first pipe section 221, and a rear muffler 212 connected to the second pipe section 222. The front muffler 211 and the rear muffler 212 are mounted between the second cross beam 122 and the third cross beam 123 through the support force of the first pipe section 221 and the second pipe section 222. By designing multiple channels, partitions, sound-absorbing materials, etc. inside the front muffler 211 and the rear muffler 212, the airflow is split and rubbed and collided with each other, gradually reducing the exhaust gas pressure and flow rate, thereby reducing the exhaust noise.

[0033] It should be noted that the first pipe section 221, the second pipe section 222, the third pipe section 223, and the fourth pipe section 224 are bent so as to better adapt to these space limitations and reasonably utilize the space under the chassis so that the exhaust pipe can be smoothly installed on the vehicle while avoiding various components such as the drive shaft, suspension system, and fuel tank.

[0034] In addition, proper bending can make the exhaust airflow form a certain turbulence in the pipe, increase the contact area and friction between the airflow and the pipe wall, which helps to reduce the exhaust speed and make the exhaust gas discharged more evenly. This is conducive to improving the exhaust efficiency of the engine, reducing the residual exhaust gas, and thus improving the performance of the engine. The curved exhaust pipe can also play a similar role as a "buffer", smoothing the exhaust pulse, reducing the fluctuation of the airflow and pressure changes, and making the exhaust process more stable. The curved part of the exhaust pipe can increase the length of the exhaust path and prolong the time that the exhaust gas stays in the pipe, which helps to consume the energy of the exhaust gas and reduce the exhaust noise.

[0035] In summary, according to a chemical vehicle exhaust tail pipe installation structure proposed by the present invention, by fixing the exhaust assembly to the second installation area, the exhaust mechanism is avoided from being arranged at the bottom of the engine, and gasoline or diesel is effectively prevented from leaking onto the exhaust pipe, thereby improving the safety factor. Specifically, the chassis mechanism includes a longitudinal beam assembly, and a cross beam assembly arranged between the longitudinal beam assemblies, and the cross beam assembly divides the space enclosed by the longitudinal beam assembly into a first installation area, a second installation area, and a third installation area; the exhaust mechanism includes a silencer assembly, and an exhaust pipe assembly for connecting the silencer assembly and the engine; wherein the exhaust mechanism is arranged in the second installation area, and is connected to the engine arranged in the first installation area through the exhaust pipe assembly, and the third installation area is used to install a cargo box.
