Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically to a carbon canister assembly with protective functions. Background Technology

[0002] As the automotive industry rapidly moves towards greener and more efficient practices, the performance and reliability of the carbon canister assembly, a core component of the fuel evaporation control system—a key system for reducing fuel evaporation emissions and improving fuel efficiency—are receiving increasing attention. The carbon canister assembly effectively reduces the amount of fuel vapors released into the atmosphere by adsorbing and desorbing fuel vapors, playing a crucial role in meeting increasingly stringent environmental regulations and reducing fuel consumption. However, traditional carbon canister assemblies face numerous technical bottlenecks in practical applications, severely limiting their performance and lifespan.

[0003] Existing carbon canister assemblies generally lack a robust protective mechanism in their structural design, making it difficult to cope with the challenges posed by the complex operating environment of vehicles. During vehicle operation, road bumps, engine vibrations, and the impact forces generated by external collisions directly affect the carbon canister. Traditional carbon canisters mostly adopt a single shell structure, lacking a design to buffer and disperse impact forces, which makes the carbon canister prone to shell damage and loosening of internal adsorbent materials under frequent vibration and impact. Utility Model Content

[0021] 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.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a carbon canister assembly with protective function, including a carbon canister assembly body 1 and an integrated component 2. The outer wall of the integrated component 2 is fixedly installed with the outer wall of the carbon canister assembly body 1. The integrated component 2 includes a blocking component 3, the inner wall of which is slidably connected to the outer wall of the carbon canister assembly body 1. An installation component 4 is fixedly installed on the outer wall of the bottom of the carbon canister assembly body 1. The blocking component 3 includes an inner cylinder 31, and a honeycomb plate 32 is fixedly connected to the outer wall of the inner cylinder 31. The honeycomb plate 32 extends along the inner cylinder. The honeycomb panel 31 is arranged in a circular array along its central axis. The inner wall of the honeycomb panel 32 is fixedly connected to a flexible plate 33, and the flexible plate 33 is arranged in a linear array along the outer wall of the honeycomb panel 32. The inner wall of the inner cylinder 31 is slidably connected to the outer wall of the carbon canister assembly 1. When subjected to external impact, it absorbs and disperses the impact force through its own deformation. When the vehicle encounters bumps, collisions, or compression, the external impact force acts on the honeycomb panel 32 first. The hexagonal grid structure of the honeycomb panel 32 decomposes the impact force into multiple directional components, effectively reducing the single-point stress intensity.

[0023] Mounting assembly 4 includes a mounting base 41. A bottom magnetic plate 44 is fixedly connected to the top of the mounting base 41, and the bottom magnetic plates 44 are arranged in a circular array along the central axis of the mounting base 41. A top plate 43 is magnetically attracted to the top of the bottom magnetic plate 44 by a permanent magnet 45, and the top of the permanent magnet 45 is fixedly connected to the bottom of the top plate 43. The permanent magnet 45 and the bottom magnetic plate 44 are magnetically attracted to each other. A claw 42 is fixedly connected to the bottom of the mounting base 41, and the claw 42 is arranged in a circular array along the central axis of the mounting base 41. The bottom of the mounting base 41 is connected to the carbon canister assembly 1. The outer walls of the carbon canister assembly 1 are in contact with each other. The outer wall of the bottom of the carbon canister assembly 1 is engaged with the outer wall of the claw 42. The top of the top plate 43 is fixedly connected to the bottom of the honeycomb plate 32. During installation, the bottom of the carbon canister assembly 1 is aligned with the mounting base 41. After the claw 42 is engaged, the top plate 43 is tightly attached to the bottom magnetic plate 44 under the magnetic force of the permanent magnet 45, forming a stable magnetic connection. The magnetic connection design makes the disassembly of the blocking component 3 more convenient. Only a certain external force needs to be applied to overcome the magnetic force to easily separate the top plate 43 and the bottom magnetic plate 44.

[0024] In automotive fuel evaporation control systems, the carbon canister assembly 1, as the core component for adsorbing and desorbing fuel vapors, directly affects the vehicle's emission performance and fuel economy. Traditional carbon canister assemblies suffer from insufficient protection and poor installation reliability when facing vibrations, impacts, external collisions, and frequent installation and disassembly during vehicle operation. This can easily lead to carbon canister damage and loose connections, thereby posing a risk of fuel vapor leakage. This protective carbon canister assembly solves the above problems through the innovative design of the integrated component 2, especially the synergistic effect of the blocking component 3 and the mounting component 4, providing comprehensive protection and stable support for the carbon canister.

[0025] The carbon canister assembly mainly consists of the carbon canister assembly body 1, the integrated component 2, the blocking component 3, and the mounting component 4. The carbon canister assembly body 1 is the core carrier for realizing the adsorption and desorption of fuel vapor. The integrated component 2, as the key structure for protection and installation, includes the blocking component 3 and the mounting component 4, which respectively undertake the functions of buffer protection and stable installation, ensuring the reliable operation of the carbon canister assembly under complex working conditions.

[0026] The blocking component 3 is the core protective unit of the carbon canister assembly against external impacts. Its key components include the inner cylinder 31, the honeycomb panel 32, and the flexible plate 33. The inner cylinder 31 is tightly fitted onto the outside of the carbon canister assembly body 1, forming the first physical protective barrier and providing an installation base for the subsequent buffer structure. The honeycomb panel 32 is arranged in a ring array along the central axis of the inner cylinder 31. Its unique honeycomb structure has excellent mechanical properties and can absorb and disperse the impact force through its own deformation when subjected to external impact. When the vehicle encounters bumps, collisions, or compression, the external impact force first acts on the honeycomb panel 32. The hexagonal grid structure of the honeycomb panel 32 decomposes the impact force into components in multiple directions, effectively reducing the single-point stress intensity. The flexible plate 33 is linearly arrayed along the inner wall of the honeycomb panel 32 and is made of highly elastic and wear-resistant flexible material to further buffer the impact force. The flexible characteristics of the flexible plate 33 can absorb high-frequency vibration energy, extend the service life of the carbon canister, and improve its impact resistance.

[0027] Mounting component 4 provides a convenient and stable installation method for the carbon canister assembly. Its core components include mounting base 41, bottom magnetic plate 44, permanent magnet 45, top plate 43, and claws 42. Mounting base 41 serves as the basic load-bearing structure. The claws 42 at the bottom quickly engage with the bottom of the carbon canister assembly 1, achieving initial positioning of mounting component 4. The bottom magnetic plate 44 is arranged in a circular array along the central axis of mounting base 41 and magnetically adsorbs with the top plate 43 through permanent magnet 45. During installation, the bottom of the carbon canister assembly 1 is aligned with mounting base 41. After the claws 42 engage, the top plate 43 is tightly attached to the bottom magnetic plate 44 under the magnetic force of permanent magnet 45, forming a stable magnetic connection. The magnetic connection design makes the disassembly process of blocking component 3 more convenient. Only a certain external force needs to be applied to overcome the magnetic force to easily separate the top plate 43 from the bottom magnetic plate 44, facilitating later maintenance, repair, and replacement.

[0028] In actual operation, when the vehicle is in motion, the honeycomb plate 32 and soft plate 33 of the blocking component 3 continuously play a buffering role, effectively reducing the impact of road bumps, engine vibration and other factors on the carbon canister total cost 1, maintaining the stability of the internal structure of the carbon canister, and ensuring the normal operation of the fuel vapor adsorption and desorption functions. In addition, when the blocking component 3 needs to be maintained, the operator can quickly disassemble the top plate 43 and easily remove the blocking component 3 by unlocking the claw 42, which improves maintenance efficiency.
