Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of automotive exhaust purification equipment, and in particular to a honeycomb ceramic carrier support for an automotive exhaust purifier. Background Technology
[0002] With the rapid development of the automotive industry, the environmental pollution caused by vehicle exhaust emissions is becoming increasingly serious, making vehicle exhaust purifiers a key device for reducing pollutant emissions. Honeycomb ceramic carriers, with their large specific surface area and low airflow resistance, serve as the core component of vehicle exhaust purifiers. They play a crucial role in loading catalysts and promoting full contact and chemical reactions between harmful components in exhaust gases (such as carbon monoxide, hydrocarbons, and nitrogen oxides) and the catalyst. Their performance and stability directly affect the exhaust purification effect.
[0003] However, in the existing technology, the performance of the honeycomb ceramic carrier support, as an important component for fixing and supporting the honeycomb ceramic carrier, directly affects the working state of the honeycomb ceramic carrier. In practical applications, the driving conditions of automobiles are complex, and factors such as road bumps and engine vibration will generate continuous and frequent vibrations and impacts. Most existing honeycomb ceramic carrier supports adopt simple rigid fixing structures. For example, some supports are directly connected to the carrier and the purifier shell by bolts. This method cannot effectively buffer external vibrations, making the honeycomb ceramic carrier prone to loosening and displacement under long-term vibration environment, resulting in catalyst coating wear and reduced exhaust gas purification efficiency. Utility Model Content
[0004] The purpose of this utility model is to solve the problems existing in the prior art and to propose a honeycomb ceramic carrier support for automobile exhaust purifiers.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a honeycomb ceramic carrier bracket for an automobile exhaust purifier, comprising a cylindrical bracket, multiple sets of trapezoidal plates fixedly installed on the inner wall of the cylindrical bracket, multiple sets of elastic buffer pads arranged inside the cylindrical bracket, three sets of buffer springs fixedly installed at one end of each set of trapezoidal plates, and an arc-shaped support block fixedly installed at one end of each set of elastic buffer pads.
[0006] Preferably, a connecting block is fixedly installed at the other end of each set of arc-shaped support blocks, and the other end of every three sets of buffer springs is fixed to the other end of a set of connecting blocks.
[0007] Preferably, a semi-circular baffle is fixedly installed on both sides of each set of arc-shaped support blocks.
[0008] Preferably, both ends of the cylindrical support are fixedly installed with ring seats, and the inner walls of both sets of ring seats are provided with multiple sets of bolts.
[0009] Preferably, the inner walls of both sets of annular seats are provided with long grooves, and one end of each set of bolts contacts the bottom of the inner end of the long grooves.
[0010] Preferably, each set of long grooves has a through-hole at the bottom, and a portion of each set of bolts is inserted into the interior of the multiple sets of mounting holes.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] 1. In this utility model, by setting an arc-shaped support block connected to a buffer spring on the inner wall of the cylindrical support, and setting an elastic buffer pad on the inner arc surface of the arc-shaped support block, the honeycomb ceramic carrier can be stably supported and effectively damped, reducing the impact of vibration and impact on the honeycomb ceramic carrier during vehicle operation and extending the service life of the honeycomb ceramic carrier. Secondly, by installing semi-circular baffles at both ends of each set of arc-shaped support blocks, the honeycomb ceramic carrier can be limited at both ends, making it convenient to fix the two ends of the honeycomb ceramic carrier and prevent it from moving inside the cylindrical support.
[0013] 2. In this utility model, with the cooperation of two sets of cylindrical brackets, multiple sets of mounting holes and multiple sets of bolts, the cylindrical brackets can be easily fixed to the outer shell of the car exhaust purifier, thereby enabling the installation and disassembly of the cylindrical brackets and the car exhaust purifier. This facilitates the assembly and disassembly of both, improves the ease of replacing or cleaning the honeycomb ceramic carrier inside the cylindrical brackets, and increases the efficiency of replacement or cleaning.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0021] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a honeycomb ceramic carrier support for an automotive exhaust purifier, including a cylindrical support 1. Multiple sets of trapezoidal plates 2 are fixedly installed on the inner wall of the cylindrical support 1. Multiple sets of elastic buffer pads 3 are provided inside the cylindrical support 1. Three sets of buffer springs 6 are fixedly installed at one end of each set of trapezoidal plates 2. Arc-shaped support blocks 9 are fixedly installed at one end of each set of elastic buffer pads 3. A connecting block 7 is fixedly installed at the other end of each set of arc-shaped support blocks 9. The other end of every three sets of buffer springs 6 is fixed to the other end of a set of connecting blocks 7. Semi-circular baffles 8 are fixedly installed on both sides of each set of arc-shaped support blocks 9.
[0022] The specific settings and functions of this embodiment are described in detail below. The core component of the bracket is a cylindrical bracket 1, on which trapezoidal plates 2 are evenly installed. The unique design of the trapezoidal plates 2 not only increases the contact area with the inner wall of the cylindrical bracket 1 and improves the installation stability, but also provides a reliable support structure for the installation of the buffer springs 6. Three sets of buffer springs 6 are vertically installed at one end of each set of trapezoidal plates 2, which effectively improves the shock absorption effect of the bracket.
[0023] The cylindrical support 1 is equipped with multiple sets of elastic buffer pads 3. Each set of elastic buffer pads 3 has an arc-shaped support block 9 fixedly installed at one end. The elastic buffer pads 3 are made of silicone material. Silicone has excellent elasticity and wear resistance. While playing a buffering role, it can effectively protect the surface of the honeycomb ceramic carrier from scratches and enhance the overall shock absorption performance. Each set of arc-shaped support blocks 9 has a connecting block 7 at one end, and its other end is firmly fixed to the other end of the corresponding three sets of buffer springs 6. This connection method allows the arc-shaped support block 9 to move flexibly under the elastic action of the buffer spring 6, so as to achieve dynamic clamping and fixing of the honeycomb ceramic carrier.
[0024] When the honeycomb ceramic carrier is placed inside the cylindrical support 1, the outer wall of the honeycomb ceramic carrier is in close contact with the inner arc surface of multiple sets of elastic buffer pads 3. During the driving process, the vehicle generates bumps and vibrations. The buffer spring 6 can effectively absorb the vibration energy and reduce the impact of vibration and impact on the honeycomb ceramic carrier through its own compression and extension, ensuring the stability of the honeycomb ceramic carrier in the support, thereby ensuring the normal operation of the vehicle exhaust purifier and the exhaust purification effect.
[0025] To further improve the fixation effect on the honeycomb ceramic carrier, semi-circular baffles 8 are installed at both ends of each set of arc-shaped support blocks 9. The semi-circular baffles 8 are integrally formed with the arc-shaped support blocks 9, and their diameter is slightly larger than that of the honeycomb ceramic carrier. This design can limit the two ends of the honeycomb ceramic carrier, effectively preventing it from moving axially inside the cylindrical support 1, facilitating the fixation of the two ends of the honeycomb ceramic carrier, and further enhancing the fixation stability of the support for the honeycomb ceramic carrier.
[0026] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, both ends of the cylindrical support 1 are fixedly installed with ring seats 4. The inner walls of the two sets of ring seats 4 are provided with multiple sets of bolts 5. The inner walls of the two sets of ring seats 4 are provided with long grooves 10. One end of the multiple sets of bolts 5 contacts the bottom of the multiple sets of long grooves 10 respectively. The bottom of the inner wall of each set of long grooves 10 is provided with a through mounting hole 11. A part of the multiple sets of bolts 5 is inserted into the interior of the multiple sets of mounting holes 11 respectively.
[0027] The overall effect of this embodiment is that at both ends of the cylindrical support 1, there are ring seats 4 respectively. The ring seat 4 is a key component for connecting the support to the outer shell of the car exhaust purifier. It has an ingenious structural design. The ring seat 4 is ring-shaped as a whole, and its inner wall is evenly distributed with multiple sets of long grooves 10. The long grooves 10 extend along the circumference of the ring seat 4, and the included angle between each set of adjacent long grooves 10 is equal. This evenly distributed design can ensure that the support is subjected to balanced force when fixed, and avoid local stress concentration.
[0028] Each long slot 10 has a through-hole 11, the diameter of which is adapted to the bolt 5, ensuring that the bolt 5 can be smoothly inserted and tightened. The long slot 10 has a dual function. On the one hand, its length provides a certain amount of room for the installation and adjustment of the bolt 5. In actual installation, even if there is a certain error in the position of the mounting hole 11 on the car exhaust purifier housing, it can be adapted by adjusting the position of the bolt 5 in the long slot 10, reducing the installation difficulty and improving the installation efficiency. On the other hand, the long slot 10 can alleviate the shear force on the bolt 5 caused by vibration during vehicle operation to a certain extent, preventing the bolt 5 from loosening and enhancing the reliability of the connection.
[0029] During installation, first place the honeycomb ceramic carrier into the cylindrical bracket 1. The buffer spring 6, elastic buffer pad 3, and arc-shaped support block 9 inside the cylindrical bracket 1 provide stable fixation and shock absorption protection for the honeycomb ceramic carrier. Then, place the cylindrical bracket 1 together with the honeycomb ceramic carrier into the car exhaust purifier housing, aligning the mounting holes 11 on the two sets of annular seats 4 with the corresponding mounting holes 11 on the car exhaust purifier housing. Next, insert the bolts 5 into the mounting holes 11 one by one and tighten them with a tool. By passing the bolts 5 through the mounting holes 11 on the two sets of annular seats 4, the bracket is firmly attached to the car exhaust purifier housing. The tightly fixed connection not only simplifies the operation, but also allows for easy removal of the cylindrical bracket 1 from the automotive exhaust purifier housing simply by unscrewing bolt 5 when the honeycomb ceramic carrier needs to be replaced or cleaned. This enables quick installation and disassembly of the cylindrical bracket 1 and the automotive exhaust purifier, greatly facilitating subsequent maintenance. Compared to traditional fixing methods, this structure eliminates the need for complex tools and cumbersome procedures, effectively improving the efficiency of replacing or cleaning the honeycomb ceramic carrier inside the cylindrical bracket 1, reducing maintenance and time costs, and providing convenience for the daily maintenance and upkeep of the automotive exhaust purifier.
[0030] The method of use and working principle of this device: First, during installation, the honeycomb ceramic carrier is placed into the cylindrical support 1. At this time, the shock absorption and fixing structure composed of the elastic buffer pad 3, the arc-shaped support block 9, the connecting block 7 and the buffer spring 6 inside the cylindrical support 1 begins to play its role. The elastic buffer pad 3 is made of silicone material. Its good elasticity and wear resistance allow the outer wall of the honeycomb ceramic carrier to fit tightly with the inner arc surface of the elastic buffer pad 3, providing initial buffer protection. The arc-shaped support block 9 is connected to the buffer spring 6 through the connecting block 7. Under the elastic action of the buffer spring 6, the arc-shaped support block 9 applies a clamping force to the honeycomb ceramic carrier, achieving a stable fixation of the honeycomb ceramic carrier. Subsequently, the cylindrical bracket 1 containing the honeycomb ceramic carrier is placed into the outer shell of the automobile exhaust purifier. The annular seats 4 at both ends of the cylindrical bracket 1 become the key components connecting the bracket and the outer shell. The multiple sets of long grooves 10 and mounting holes 11 on the inner wall of the annular seat 4 play an important role. The long grooves 10 are evenly distributed along the circumference, providing a certain adjustment space for the installation of bolts 5. Even if there is a positional error in the mounting holes 11 on the purifier outer shell, the alignment can be completed by adjusting the position of the bolts 5 in the long grooves 10. The bolts 5 are inserted into the mounting holes 11 and tightened to achieve a firm connection between the bracket and the outer shell of the automobile exhaust purifier, ensuring the stable installation of the entire bracket inside the purifier.
[0031] Finally, when a car is in motion, it inevitably encounters bumps and vibrations. At this time, the shock absorption function of the bracket is crucial. As the core shock absorption component, the buffer spring 6 can effectively absorb the vibration energy transmitted to the bracket during vehicle operation. When subjected to vibration and impact, the buffer spring 6 will undergo corresponding compression or extension deformation according to the magnitude of the impact force, converting the vibration energy into the elastic potential energy of the spring, thereby reducing the impact of vibration and impact on the honeycomb ceramic carrier. At the same time, the elastic buffer pad 3 also plays an indispensable role. It can further buffer minor vibrations and contact stress, preventing the honeycomb ceramic carrier from being damaged by direct hard contact with the arc-shaped support block 9. The dual shock absorption structure works together to ensure the stability of the honeycomb ceramic carrier in the bracket, enabling it to work continuously and normally, and ensuring the exhaust purification effect of the car exhaust purifier.
[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
