Description

Technical Field

[0001] This utility model belongs to the field of engine aftertreatment technology, and specifically refers to an integrated aftertreatment fixing device and engine assembly. Background Technology

[0002] With the increasing emphasis on environmental protection and the development of diesel engine after-treatment technology, after-treatment mechanisms have become increasingly complex. Prior to China III emission standards (including China III), compliance with emission regulations primarily relied on the engine's own in-engine purification technology. However, after China IV emission standards were implemented, relying solely on the engine's in-engine purification was insufficient to meet stringent emission limits, necessitating the integration of a series of after-treatment technologies. The mainstream after-treatment technology is SCR technology, with DPF devices added when necessary. The after-treatment mounting system is a crucial component for securing related after-treatment parts. Different structures often require separate brackets for installation, resulting in low integration, complex structures, and large space requirements. Furthermore, the numerous separate brackets increase weight, hindering vehicle weight reduction and increasing costs. Utility Model Content

[0022] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the embodiments, unless otherwise stated, the terms "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the present application must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present application.

[0023] like Figure 1 As shown, this utility model provides an integrated post-processing fixing device, mainly including a first bracket 101, a second bracket 102, and a third bracket 103. The first bracket 101 and the second bracket 102 are detachably connected, as are the second bracket 102 and the third bracket 103. A preset distance is provided between the first bracket 101 and the third bracket 103 to create clearance space, making the installation structure of the first bracket 101, second bracket 102, and third bracket 103 more compact and space-saving. A second mounting position is provided on the second bracket 102, a first connecting part is provided on the first bracket 101, and a third connecting part is provided on the third bracket 103. Both the first and second connecting parts are connected to an external structure, thus providing a horizontal second mounting position for the second bracket 102.

[0024] Specifically, the first bracket 101 is provided with a first fixing hole 1011, the second bracket 102 is provided with a number of second fixing holes 10212 corresponding to the number and position of the first fixing holes 1011, and they are connected by bolts. The third bracket 103 is provided with a third fixing hole 1033, and the second bracket 102 is provided with a fourth fixing hole 10222 corresponding to the number and position of the third fixing holes 1033, and they are detachably connected by bolts.

[0025] In this embodiment, the connection of the first bracket 101, the second bracket 102, and the third bracket 103 can be disassembled, which enables the pre-installation of the corresponding mounting components of the first bracket 101, the second bracket 102, and the third bracket 103. Then, the first bracket 101 and the third bracket 103 are connected by the second bracket 102 to form a whole, so that the mounting components located on the second bracket 102 have a stable mounting support structure.

[0026] Furthermore, the second bracket 102 is set horizontally so that the second bracket 102 can fully support the component installed in the second mounting position.

[0027] In one embodiment, to maintain a stable support structure for the second bracket 102, the first bracket 101 and the third bracket 103 are arranged perpendicularly to the second bracket 102. In this embodiment, both the first bracket 101 and the third bracket 103 are sheet-like structures of a certain thickness and width, which can occupy a small installation space while ensuring the support strength of the first bracket 101 and the third bracket 103.

[0028] In one embodiment, the second bracket 102 is provided with a first mounting surface 1021 and a second mounting surface 1022, with a certain height difference between the first mounting surface 1021 and the second mounting surface 1022, the second mounting surface 1022 being higher than the first mounting surface 1021. In this embodiment, by providing a first mounting surface 1021 and a second mounting surface 1022 with a height difference, clearance space is provided below the second mounting surface 1022, allowing the second bracket 102 to be installed close to the body, thus reducing the installation space occupied by the second bracket 102.

[0029] In one embodiment, to facilitate the assembly of the second bracket 102 and improve its support strength, the second bracket 102 is integrally formed. The first mounting surface 1021 and the second mounting surface 1022 are arranged in parallel. A bent connecting rib 1023 is provided between the second mounting surface 1022 and the first mounting surface 1021. The bent connecting rib 1023 is perpendicular to both the first mounting surface 1021 and the second mounting surface 1022. By providing the bent connecting rib 1023, a clearance space is formed below the second mounting surface 1022.

[0030] In one embodiment, in order to facilitate the lightweighting of the second support 102, a plurality of first hollow slots are provided on the second support 102. The plurality of first hollow slots are distributed at intervals. While ensuring the support strength of the second support 102, the first hollow slots reduce the weight of the second support 102.

[0031] In one embodiment, the third bracket 103 includes a first leg 1031 and a second leg 1032, with a preset distance between the first leg 1031 and the second leg 1032 to ensure the stability of the installation structure of the third bracket 103. Simultaneously, a clearance space can also be formed between the first leg 1031 and the second leg 1032, allowing the third bracket 103 to avoid obstacles during installation, resulting in a more compact installation.

[0032] In one embodiment, such as Figure 2The present invention provides an engine assembly including the integrated aftertreatment fixing device in the above embodiments; an engine body 300, and a first bracket 101 detachably mounted on the engine body 300. In this embodiment, the first bracket 101 is mounted on the flywheel housing of the engine body 300 and is detachably connected by bolts. The third bracket 103 is detachably mounted on the engine body 300 by bolts; the aftertreatment mechanism includes a first processor 201 and a second processor 202. The first processor 201 is fixed to the fifth fixing hole 10211 of the first mounting surface 1021 by a shock-absorbing pad 2011, and the second processor 202 is fixed to the sixth fixing hole 10211 of the second mounting surface 1022 by a shock-absorbing pad 2011. The first processor 201 and the second processor 202 are connected. The second processor 202 is connected to the exhaust port of the engine body 300 through an exhaust pipe 301. The exhaust pipe is locked and fixed by a clamp. The angles of the exhaust port of the engine body 300 and the air intake of the second processor 202 can be rotated and adjusted, thereby effectively shortening the length of the exhaust pipe 301 and saving installation space.

[0033] In this application, the aftertreatment structure is mounted above the engine body 300 via the first bracket 101, the second bracket 102, and the third bracket 103. On the one hand, the overall structure is compact, the aftertreatment mechanism is detachably connected to the second bracket 102, and the first bracket 101 and the second bracket 102 are detachably connected, as are the second bracket 102 and the third bracket 103. This facilitates the overall disassembly of the aftertreatment mechanism and makes it convenient for the inspection and maintenance of the aftertreatment structure.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model. These improvements and modifications should also be considered within the scope of protection of this utility model.
