Description

Technical Field

[0001] This utility model belongs to the field of exhaust gas purification technology, and in particular relates to a motor vehicle exhaust gas filtration and purification device. Background Technology

[0002] Motor vehicle exhaust filtration and purification is a purification technology that filters pollutants in motor vehicle exhaust to ensure that emissions meet standards. Particulate filters are key devices in motor vehicle exhaust filtration and purification, mainly used to capture particulate matter in diesel vehicle exhaust. Its core structure is a honeycomb porous ceramic carrier with a catalytic coating on the surface. When exhaust gas passes through, particulate matter is intercepted in the pores. When the particulate matter in the filter accumulates to a certain level, it can be actively or passively regenerated by using high temperature to burn the particulate matter into carbon dioxide and discharge it, ensuring filtration efficiency and effectively reducing particulate matter emissions in exhaust gas to meet environmental standards. It is an important technical means for reducing emissions from diesel vehicles.

[0003] Existing vehicle exhaust filtration and purification devices are not convenient for installing particulate filters on vehicles. During installation, staff need to repeatedly locate the particulate filters and perform complex operations, which is time-consuming and labor-intensive, greatly reducing the installation efficiency of particulate filters. Utility Model Content

[0004] The purpose of this utility model is to provide a motor vehicle exhaust gas filtration and purification device. By setting up an installation part, it solves the problem that existing motor vehicle exhaust gas filtration and purification devices are inconvenient to install the particulate filter on the vehicle during use. During the installation process, it is necessary for the staff to repeatedly locate and perform complicated operations, which is time-consuming and labor-intensive, and greatly reduces the installation efficiency of the particulate filter.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a vehicle exhaust gas filtration and purification device, including a particulate filter. The particulate filter has an external mounting portion, which includes a bracket assembly and several locking components. The bracket assembly includes a connecting block located at the top of the particulate filter. A base is located at the bottom of the particulate filter, and two rotating parts are located at the top of the base. A second limiting block (U-shaped) with its opening facing downwards is slidably connected to the inner wall of the connecting block. Each rotating component includes a first limiting block fixedly connected to the top of the connecting block. A hinge block is hinged to the top of the base, and the top of the hinge block is fixedly connected to a locking block located on the right side. The connecting block and the base lock the particulate filter in place.

[0007] Furthermore, the locking component includes a locking block slidably connected to the inner wall of the connecting block. A limiting block three is slidably connected to the inner wall of the connecting block, and a limiting block four is slidably connected to the inner wall of the locking block. An elastic element is provided within the limiting block four. The bottoms of the two locking blocks on the left side are fixedly connected to the base, and the tops of the two locking blocks on the right side are fixedly connected to the limiting block two. Each locking block is a block with several slots. The side of the limiting block three closest to the locking block is adapted to the locking block. The elastic element includes a limiting block five slidably connected to the inner wall of the limiting block four. The side of the limiting block five closest to the locking block is fixedly connected to the limiting block three. A spring is provided on the outer wall of the limiting block five. The limiting block five passes through the limiting block four. The side of the spring closest to the limiting block four is fixedly connected to the limiting block four, and the side of the spring closest to the limiting block three is fixedly connected to the limiting block three. When the limiting block three is subjected to force, it will push the limiting block five to slide within the limiting block four without affecting the operation of the limiting block four.

[0008] Furthermore, the particle collector is provided with an unlocking part above it, which includes a rotating component and a pushing component.

[0009] Furthermore, the rotating assembly includes a rotating shaft rotatably connected to the inner wall of the connecting block. Gear 1 and Gear 2 are fixedly connected to the outer wall of the rotating shaft. Two racks 1 are slidably connected to the inner wall of the connecting block. Both racks 1 mesh with gear 2. The sides of the two racks 1 that are far apart from each other are fixedly connected to four limiting blocks 4 respectively. The rotating shaft passes through gear 1 and gear 2, and the two racks 1 are circumferentially distributed, which can simultaneously pull the four limiting blocks 4, thereby ensuring the efficiency of disassembling the particle collector.

[0010] Furthermore, the pushing component includes a groove formed on the front side of the connecting block, and a rack two is slidably connected to the inner wall of the groove, wherein the rack two meshes with a gear one and can provide power for the rotation of the gear one.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up the installation section, when installation is required, the particle trap can be placed on the connecting block, and then the base can be lifted and rotated under the action of the two hinge blocks. When the base rotates to a certain extent, the base will be kept parallel to the connecting block under the action of the first limiting block. Then the base can be pushed upward, causing the four locking blocks to slide upward and slide into the connecting block. During this process, the third limiting block will be pushed, causing the fifth limiting block to slide within the fourth limiting block, and the spring will be compressed and generate elastic force, while the fourth limiting block will not move. When the locking blocks are completely slid into the connecting block, the third limiting block will lock the locking blocks under the action of the spring force, which facilitates installation. During the assembly process, the operator does not need to repeatedly position the device. Only simple operations are needed to install the particle trap onto the vehicle, thereby improving the installation efficiency of the particle trap.

[0013] 2. By setting an unlocking mechanism, when it is necessary to disassemble the particle trap, you can insert your finger into the slide groove and push rack two to make it drive gear one to rotate. At this time, gear one will drive gear two to rotate through the shaft. Then, the two racks one will move closer to each other, thereby moving the two limit blocks four on the left and the two limit blocks four on the right closer to each other. This will cause limit block three to move away from the jamming block through several limit blocks five, thereby unlocking the jamming block. Then the base can be lowered, and the particle trap can be removed. This can simultaneously unlock all four jamming blocks and lower the base, making the disassembly of the particle trap simple and improving the efficiency of particle trap replacement.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figure 1-8 As shown, this utility model is a motor vehicle exhaust gas filtration and purification device, including a particulate filter 101, an installation part 2, and an unlocking part 3. The installation part 2 is disposed outside the particulate filter 101, and the unlocking part 3 is disposed above the particulate filter 101, wherein the unlocking part 3 is located inside the installation part 2.

[0028] The mounting section 2 includes a support assembly 21 and locking assemblies 22. The support assembly 21 is located outside the particle trap 101. Four locking assemblies 22 are provided, all located inside the support assembly 21, and are arranged in an array. The support assembly 21 includes a connecting block 211 at the top of the particle trap 101, and a base 212 at the bottom of the particle trap 101. Two rotating parts are provided on the top of the base 212. A limit block 215 is slidably connected to the inner wall of the connecting block 211. In the middle, the limiting block 215 is a C-shaped block with its opening facing downwards. The rotating component includes a limiting block 213 fixedly connected to the top of the connecting block 211. The top of the base 212 is hinged to a hinge block 214, wherein the top of the hinge block 214 is fixedly connected to the locking block 221 located on the right side. The locking component 22 includes a locking block 221 slidably connected to the inner wall of the connecting block 211. The inner wall of the connecting block 211 is slidably connected to a limiting block 222, and the inner wall of the locking block 221 is slidably connected to a limiting block 223. The limiting block 213 located on the left side is... The bottoms of both locking blocks 221 are fixedly connected to the base 212, and the tops of the two right-side locking blocks 221 are fixedly connected to the limiting block 215. Each locking block 221 has several locking slots. The limiting block 3 222 is located near the locking block 221 and is adapted to it. The limiting block 4 223 contains an elastic element, including a limiting block 5 224 that is slidably connected to the inner wall of the limiting block 4 223. The limiting block 5 224 is fixedly connected to the limiting block 3 222 on the side near the locking block 221. The outer wall of 4 is provided with a spring 225, wherein the limiting block 5 224 passes through the limiting block 4 223, the side of the spring 225 near the limiting block 4 223 is fixedly connected to the limiting block 4 223, and the side of the spring 225 near the limiting block 3 222 is fixedly connected to the limiting block 3 222. By setting the mounting part 2, it is easy to install. During the assembly process, the operator does not need to repeatedly position it. Only a simple operation is needed to install the particle collector 101 onto the vehicle, thereby improving the installation efficiency of the particle collector 101.

[0029] The unlocking part 3 is located among several locking components 22. The unlocking part 3 includes a rotating component 31 and a pushing component 32. The rotating component 31 is located above the particle trap 101, and the pushing component 32 is located above the particle trap 101. The rotating component 31 includes a rotating shaft 311 rotatably connected to the inner wall of the connecting block 211. A gear 312 is fixedly connected to the outer wall of the rotating shaft 311, and a gear 313 is fixedly connected to the outer wall of the rotating shaft 311. Two racks 314 are slidably connected to the inner wall of the connecting block 211. Both racks 314 mesh with the gears 313, and the two racks 314 are far apart from each other. One side is fixedly connected to four limiting blocks 223 respectively. The rotating shaft 311 passes through the first gear 312 and the second gear 313. The two racks 314 are circumferentially distributed. The pushing component 32 includes a sliding groove 321 opened on the front side of the connecting block 211. The inner wall of the sliding groove 321 is slidably connected to the second rack 322. The second rack 322 meshes with the first gear 312. By setting the unlocking part 3, the four locking blocks 221 can be unlocked at the same time, and the base 212 can be lowered, making the disassembly of the particle collector 101 simple and thus improving the efficiency of replacing the particle collector 101.

[0030] A specific application of this embodiment is as follows: In use, the top of the connecting block 211 is fixed to the vehicle by welding. When installation is required, the particulate trap 101 can be placed on the connecting block 211, and then the base 212 can be lifted so that it can rotate under the action of the two hinge blocks 214. When the base 212 rotates to a certain extent, the limiting block 1 213 will keep the base 212 parallel to the connecting block 211. Then the base 212 can be pushed upward so that it drives the four locking blocks 221 to slide upward and slide into the connecting block 211. During this process, the limiting block 3 222 will be pushed so that the limiting block 5 224 will slide within the limiting block 4 223, and the spring 225 will be compressed and generate elastic force, while the limiting block 4 223 will not move. When the locking block 221 is fully slid into the connecting block 211, the limiting block 3 222 will lock the locking block 221 under the action of the spring 225. When it is necessary to disassemble the particle collector 101, you can put your finger into the slide groove 321 and push the rack 2 322 to drive the gear 1 312 to rotate. At this time, the gear 1 312 will drive the gear 2 313 to rotate through the rotating shaft 311. At this time, the two racks 1 314 will move closer to each other, thereby driving the two limiting blocks 4 223 on the left and the two limiting blocks 4 223 on the right to move closer to each other. Thus, through several limiting blocks 5 224, the limiting block 3 222 will be driven away from the locking block 221, thereby unlocking the locking block 221. Then the base 212 can be put down. At this time, the particle collector 101 can be removed.
