Technical Field

[0001] This utility model relates to the field of exhaust gas devices, and in particular to an exhaust gas device for automobile modification. Background Technology

[0002] With the booming development of the automotive industry and the continuous increase in car ownership, the environmental impact of vehicle exhaust emissions is becoming increasingly significant. Exhaust systems, as key devices for controlling vehicle emissions, play a crucial role in reducing pollution and protecting the environment. Whether in small cars used for urban commuting or long-haul trucks, exhaust systems are indispensable. They are not only related to air quality but also closely linked to people's health, becoming an important indicator of a vehicle's environmental performance and attracting widespread attention from all sectors of society.

[0003] Currently, traditional automotive exhaust systems have numerous problems. In terms of installation, traditional systems are complex and unstable. They typically require multiple tools and tedious operations, consuming significant time and effort, resulting in low installation efficiency. Furthermore, their fixing methods are often unreliable; during vehicle operation, vibrations and bumps can easily cause the exhaust pipe and outlet pipe to loosen or detach. This not only leads to exhaust leaks and environmental pollution but also poses safety hazards and affects the normal operation of the vehicle. Traditional systems also have shortcomings in exhaust filtration and maintenance. The filtration effect of exhaust filters is limited, making it difficult to effectively adsorb pollutants such as carbon particles in exhaust gases, failing to meet increasingly stringent environmental standards. Moreover, replacing filters in traditional systems is difficult. Due to unreasonable structural design, multiple components need to be disassembled, and sometimes even specialized technicians with special tools are required to complete the replacement, increasing maintenance and time costs. For ordinary car owners, the difficulty of frequently replacing filters leads to delayed replacements, a gradual decline in filtration effectiveness, and further exacerbation of exhaust pollution problems.

[0004] In response to this technical problem, this application proposes an exhaust device for automobile modification. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vehicle exhaust system that ensures the stability of the pipe installation, reduces the risk of pipe loosening or detachment, improves the reliability of the entire exhaust system, and reduces maintenance difficulty and cost. The convenient maintenance process allows users to replace the filter element promptly, ensuring consistently good exhaust filtration and extending the service life of the exhaust pipe.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vehicle exhaust system includes a pre-installed mounting plate. An exhaust pipe is mounted on the bottom side of the mounting plate. An exhaust transport pipe is fixedly connected to the top side of the exhaust pipe. An outlet pipe is fixedly connected to the left end of the exhaust transport pipe. A positioning baffle is rotatably connected to the bottom side of the mounting plate via a pre-set rotating shaft. A pre-set limiting post is fixedly connected to the right side of the positioning baffle. A pre-set positioning plate is fixedly connected to the bottom side of the mounting plate. The pre-set limiting post is connected to the pre-set positioning plate via a clamping assembly. A pre-set connector is connected to the rear end of the exhaust pipe via a connecting assembly. Limiting connecting plates are fixedly connected to both ends of the pre-set connector.

[0008] Furthermore, the clamping assembly includes two arc-shaped clamping plates rotatably connected to the bottom side of the preset positioning plate, and a return spring is provided on the bottom side of the reserved mounting plate.

[0009] Furthermore, one end of the reset spring is connected to the bottom side of the preset positioning plate, and the other end is connected to the top side of the arc-shaped clamping plate. The adjacent sides of the two arc-shaped clamping plates are in contact with the outer wall of the preset limiting post.

[0010] Furthermore, the connecting assembly includes two preset fixing plates fixedly connected to the rear end of the exhaust pipe. Each of the two preset fixing plates has an adjusting slide rod slidably connected inside. Each of the two adjusting slide rods has an adjusting cap threadedly connected to its front end. Each of the two adjusting slide rods has a limit adjusting ring rotatably connected to its rear end.

[0011] Furthermore, two preset limiting strips are fixedly connected to the outer walls of both adjusting slide rods, and the outer walls of the two preset limiting strips are slidably connected to the inside of the limiting connecting plate.

[0012] Furthermore, the limiting adjustment ring has through grooves at both the top and bottom, and semi-through grooves at both the left and right ends.

[0013] Furthermore, multiple exhaust gas filter elements are slidably connected inside the exhaust gas emission pipe.

[0014] Furthermore, two preset limit blocks are fixedly connected to the rear ends of both adjusting slide rods.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when installing the exhaust pipe and outlet pipe, they are placed in the placement groove of the reserved mounting plate. Through simple operations such as rotating the positioning baffle and pressing the arc-shaped clamp, the preset limit post is clamped and fixed using a return spring, completing the pre-positioning of the outlet pipe installation. Finally, reinforcing bolts are used for final fixation. This installation method is simple to operate, saves installation time, and the combination of pre-positioning and final fixation ensures the stability of the pipe installation, reduces the risk of pipe loosening or falling off, and improves the reliability of the entire exhaust system.

[0017] 2. In this utility model, when installing or replacing the exhaust gas filter element, the adjusting cap button is rotated, and the adjusting slide rod is moved horizontally using the threaded connection and limiting structure, thereby easily removing the limiting adjusting ring and disassembling the preset connector. This design makes the filter element replacement operation simple and convenient, reducing maintenance difficulty and cost. The convenient maintenance process allows users to replace the filter element in a timely manner, ensuring that the exhaust gas filtration effect is always good and extending the service life of the exhaust gas emission pipe.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 This utility model provides an embodiment of an exhaust device for automotive modification, comprising a pre-installed mounting plate 1, an exhaust pipe 2 disposed on the bottom side of the pre-installed mounting plate 1, an exhaust transport pipe 4 fixedly connected to the top side of the exhaust pipe 2, an outlet pipe 3 fixedly connected to the left end of the exhaust transport pipe 4, a positioning baffle 14 rotatably connected to the bottom side of the pre-installed mounting plate 1 via a preset rotating shaft 13, a preset limiting post 16 fixedly connected to the right side of the positioning baffle 14, a preset positioning plate 19 fixedly connected to the bottom side of the pre-installed mounting plate 1, the preset limiting post 16 being connected to the preset positioning plate 19 via an arc-shaped clamp 17, and a preset connector 5 connected to the rear end of the exhaust pipe 2 via an adjusting slide rod 8, with limiting connecting plates 12 fixedly connected to both ends of the preset connector 5. Multiple exhaust filter elements 15 are slidably connected inside the exhaust pipe 2.

[0025] Specifically, the installation steps for the exhaust pipe 2 and the outlet pipe 3 in the installation of a vehicle modification exhaust system are designed very reasonably. At the start of installation, the operator first places the exhaust pipe 2 and the outlet pipe 3 into the pre-cut slots on the bottom side of the pre-installed mounting plate 1, laying the foundation for subsequent installation. Next, the positioning baffle 14 is rotated to a horizontal position, ensuring that the top side of the positioning baffle 14 fits tightly against the bottom side of the pre-installed mounting plate 1. Regarding exhaust filtration, multiple exhaust filter elements 15 are installed inside the exhaust pipe 2. These filter elements play a crucial environmental protection role. They effectively filter the exhaust gases produced by the vehicle, focusing on the concentrated adsorption and collection of carbon particles in the exhaust gases, thereby preventing the direct emission of carbon particles into the environment and greatly reducing the pollution caused by vehicle exhaust.

[0026] Reference Figure 2 Two arc-shaped clamping plates 17 are rotatably connected to the bottom side of the preset positioning plate 19, and a return spring 18 is provided on the bottom side of the reserved mounting plate 1. One end of the return spring 18 is connected to the bottom side of the preset positioning plate 19, and the other end is connected to the top side of the arc-shaped clamping plate 17. The adjacent sides of the two arc-shaped clamping plates 17 are in contact with the outer wall of the preset limiting post 16.

[0027] Specifically, the operator presses down on the two arc-shaped clamps 17 to open them, and then places the preset limiting post 16 on the positioning baffle 14 between the two arc-shaped clamps 17. When the operator releases the arc-shaped clamps 17, the elastic potential energy generated by the previous deformation of the return spring 18 begins to function, assisting the arc-shaped clamps 17 in firmly clamping and fixing the preset limiting post 16, thus successfully achieving the pre-positioning of the air outlet pipe 3. After pre-positioning, the operator uses reinforcing bolts to finally fix the air outlet pipe 3, ensuring that the air outlet pipe is installed securely.

[0028] Reference Figure 3The exhaust pipe 2 has two pre-set fixing plates 6 fixedly connected to its rear end. Each pre-set fixing plate 6 has an adjusting rod 8 slidably connected inside it. Each adjusting rod 8 has an adjusting cap 7 threadedly connected to its front end. Each adjusting rod 8 has a limit adjusting ring 11 rotatably connected to its rear end. Each adjusting rod 8 has two pre-set limiting strips 9 fixedly connected to its outer wall, and the outer walls of the two pre-set limiting strips 9 are slidably connected inside a limit connecting plate 12. The limit adjusting ring 11 has through grooves at its top and bottom, and semi-through grooves at both its left and right ends. Each adjusting rod 8 has two pre-set limiting blocks 10 fixedly connected to its rear end.

[0029] Specifically, the installation or replacement of the exhaust filter element 15 is relatively simple. The operator rotates the adjusting cap 7, utilizing the threaded connection principle and the limiting effect of the limiting connecting plate 12 on the preset limiting strip 9, ensuring that the adjusting slide rod 8 can only move horizontally within the limiting connecting plate 12. During this process, the preset limiting block 10 at the rear end of the adjusting slide rod 8 disengages from the semi-through groove on the limiting adjusting ring 11. Then, by rotating the through groove on the limiting adjusting ring 11 to align with the preset limiting block 10, the limiting adjusting ring 11 can be easily removed. Subsequently, the preset connector 5 can also be easily disassembled, enabling subsequent operations such as the installation and replacement of the exhaust filter element 15.

[0030] Working principle: When installing the exhaust pipe 2 and the outlet pipe 3, the operator can place them in the placement groove opened on the bottom side of the reserved mounting plate 1, and then rotate the positioning baffle 14 to a horizontal position so that the top side of the positioning baffle 14 fits against the bottom side of the reserved mounting plate 1. At this time, the operator presses the two arc-shaped clamps 17 to open them, and puts the preset limiting post 16 on the positioning baffle 14 between the two arc-shaped clamps 17. The operator releases the arc-shaped clamps 17, and with the assistance of the elastic potential energy generated by the deformation of the return spring 18, the preset limiting post 16 is clamped and fixed, thereby realizing the pre-positioning of the outlet pipe 3. After positioning, the operator can finally fix the outlet pipe 3 with the reinforcing bolts.

[0031] Multiple exhaust gas filter elements 15 installed inside the exhaust pipe 2 can filter the exhaust gas generated by the vehicle, aiming to centrally adsorb and collect carbon particles in the exhaust gas to avoid direct emission and environmental pollution. When installing or replacing the exhaust gas filter element 15, the operator can rotate the adjusting cap button 7. Under the limiting action of the threaded connection and the limiting connecting plate 12 on the preset limiting strip 9, the adjusting slide rod 8 can only move in a straight line in the horizontal direction inside the limiting connecting plate 12. At this time, the preset limiting block 10 at the rear end of the adjusting slide rod 8 disengages from the semi-through groove on the limiting adjusting ring 11. Then, the through groove on the limiting adjusting ring 11 is rotated to the position aligned with the preset limiting block 10 to remove the limiting adjusting ring 11. Then, the preset connector 5 is disassembled to realize the subsequent operation of the exhaust gas filter element 15.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
