[0119] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative labor fall within the protection scope of the present application.
[0120] According to a first aspect of the present application, with reference to Figures 1 to 4 The present application provides a tail gas device 100, comprising a device body 110 and a mounting support.
[0121] The device body 110 is used for processing tail gas discharged by a power assembly 200 of a vehicle 1; the mounting support is used for mounting the device body 110 to the power assembly 200; and the mounting support is arranged on the outer side of the device body.
[0122] It can be understood that the power assembly 200 comprises an engine and a motor, wherein the engine discharges tail gas when working, and the device body 110 processes the tail gas discharged by the power assembly 200. The device body 110 comprises at least one of a muffler 111 and a catalyst 112.
[0123] Through the above technical solution, the device body 110 is mounted to the power assembly 200 by arranging the mounting support on the outer side of the device body 110, the support of the device body 110 is realized by the power assembly 200, and the whole composed of the power assembly 200 and the device body 110 can be hoisted together into the vehicle 1, thereby facilitating the assembly of the whole of the tail gas device 100 and the power assembly 200 and the vehicle.
[0124] In some embodiments of the present application, with reference to Figures 1 to 4 The mounting support is configured to mount the device body 110 to the power assembly 200 along a first direction; wherein the mounting support and the device body 110 are arranged at different positions in a second direction, and the second direction intersects the first direction.
[0125] It should be noted that the device body 110 as a whole is matched with the power assembly 200 in the first direction. Here, the first direction indicates the front-rear direction only for the convenience of introducing the specific embodiments of the present application. The first direction does not have an absolute corresponding relationship with the front-rear direction. That is, at least part of the device body 110 can be installed on the front side of the power assembly 200, or can be installed on the left side, right side, etc. of the power assembly 200.
[0126] Similarly, the second direction and the third direction do not have an absolute corresponding relationship with the left-right direction and the up-down direction. The first direction, the second direction, and the third direction of the present application only express the relative positional relationship. They only indicate the approximate orientation, not the absolute geometric relationship.
[0127] It should be noted that the mounting bracket and the device body 110 are arranged at different positions in the second direction. It can be understood that the connection between the mounting bracket and the device body 110 is arranged on the outer wall of the device body 110 in the second direction. Alternatively, the mounting bracket as a whole is arranged on the outer wall of the device body 110 in the second direction. That is, the mounting bracket is arranged on the outside of the whole formed by the device body 110 and the power assembly 200, so as to ensure that the arrangement of the mounting bracket does not affect the installation gap between the device body 110 and the power assembly 200.
[0128] By the above technical solution, the mounting bracket and the device body 110 are arranged at different positions in the second direction. The mounting bracket is arranged on the outside of the device body 110, avoiding the mounting bracket being blocked by the device body 110 or the power assembly 200, facilitating the connection between the mounting bracket and the power assembly 200. Moreover, the arrangement of the mounting bracket does not increase the installation gap between the device body 110 and the power assembly 200, reducing the influence on the volume of the whole formed by the power assembly 200 and the device body 110, and improving the stability of the installation.
[0129] In some specific embodiments, the mounting bracket is fixedly connected to the device body 110 by welding, bolt connection, etc.
[0130] In some embodiments of the present application, referring to Figures 1 to 4 The tail gas device 100 includes a plurality of mounting brackets. The plurality of mounting brackets are arranged at intervals around the circumference of the device body 110 in the first direction.
[0131] It can be understood that the plurality of mounting brackets are arranged at intervals around the circumference of the device body 110. The plurality of mounting brackets can be arranged at equal intervals or non-equal intervals.
[0132] By the arrangement of the plurality of mounting brackets, the stability of the device body 110 is improved.
[0133] In some embodiments of the present application, referring to Figures 1 to 4 , the device body 110 is provided with mounting brackets on opposite sides in the second direction.
[0134] It can be understood that the circumferential side of the device body 110 has a plurality of sides, and the mounting brackets are arranged on two opposite sides thereof.
[0135] With such a scheme, by providing mounting brackets on opposite sides of the device body 110 in the second direction, stable support for the device body 110 is ensured.
[0136] In some specific embodiments, the length of the device body 110 in the up-down direction is greater than the length of the device body 110 in the left-right direction, and mounting brackets are arranged on the left and right sides of the device body 110, facilitating the arrangement of the mounting brackets while ensuring stable support for the device body 110.
[0137] In some embodiments of the present application, referring to Figures 1 to 4 , at least two mounting brackets are arranged on opposite sides of the device body 110 in the second direction. Adjacent mounting brackets are arranged in the third direction (up-down direction), and the spacing between adjacent mounting brackets on each side can be selected according to the structure of the power assembly 200.
[0138] With such a scheme, by arranging at least two mounting brackets on opposite sides of the device body 110 in the second direction, the weight of the device body 110 can be better shared, and the overall modal of the device body 110 can be improved, avoiding the phenomenon of resonance between the device body 110 and the power assembly 200 and the problem of durable fracture of the bracket,
[0139] In some embodiments of the present application, referring to Figure 5 , Figure 7 , Figure 9 , Figure 10 , Figure 12 and Figure 13 , the mounting bracket comprises a first fixing portion 121 and a first connecting portion 122.
[0140] The first fixing portion 121 is fixedly connected to the device body 110; the first connecting portion 122 is used to be connected to the power assembly 200; the first connecting portion 122 is arranged on the side of the first fixing portion 121 away from the device body 110, so that at least part of the first connecting portion 122 is spaced apart from the device body 110, facilitating the connection of the first connecting portion 122 to the power assembly 200.
[0141] With the arrangement, the first fixing part 121 and the first connecting part 122 are arranged to facilitate the connection of the mounting bracket with the device body 110 and the power assembly 200.
[0142] In some specific embodiments, the first fixing part 121 can be welded to the device body 110, i.e., the mounting bracket can be pre-welded to the device body 110. When the exhaust device 100 is assembled with the power assembly 200, only the first connecting part 122 needs to be connected with the power assembly 200, thereby improving the assembly efficiency.
[0143] In some specific embodiments, the mounting bracket includes a first mounting bracket 120a and a second mounting bracket 120b arranged on the right side of the device body 110, and a third mounting bracket 120c and a fourth mounting bracket 120d arranged on the left side of the device body 110.
[0144] Referring to Figure 1 , Figure 5 and Figure 7 , the first fixing part 121 of the first mounting bracket 120a and the second mounting bracket 120b respectively forms a C-shaped structure, thereby improving the connection stability between the first fixing part 121 and the device body 110, and the first connecting part 122 extends away from the device body 110 by a certain distance relative to the first fixing part 121. In the present embodiment, the first connecting part 122 of the first mounting bracket 120a and the second mounting bracket 120b is arranged perpendicularly to the right side of the device body 110.

[0146] In some embodiments of the present application, the first connecting part 122 is configured to have a first mounting structure for connecting the first connecting part 122 to the power assembly 200.
[0147] In some specific embodiments, the first mounting structure can be one of a bolt hole, a clamping structure, and a concave-convex structure.
[0148] In some embodiments of the present application, referring to Figure 5 ,Figure 7 、 Figure 9 、 Figure 10 、 Figure 12 and Figure 13 The first mounting structure comprises a first mounting hole 122a. The first mounting hole 122a penetrates the first connecting part 122, and is used for passing a fastener 230 connecting the first connecting part 122 and the power assembly 200.
[0149] With the above scheme, the first connecting part 122 is connected with the power assembly 200 through the fastener 230 by the first mounting hole 122a, so that the mounting bracket can bear at least part of the weight of the device body 110.
[0150] In some specific embodiments, the fastener 230 comprises one of a bolt, a pin shaft. Correspondingly, the first mounting hole 122a can be one of a bolt hole, a taper hole.

[0152] In some embodiments of the present application, with reference to Figure 2 、 Figure 9 、 Figure 10 、 Figure 12 and Figure 13 The penetrating direction of the first mounting hole 122a intersects the first direction.
[0153] It can be understood that the penetrating direction of the first mounting hole 122a can be obliquely intersected or perpendicularly intersected with the first direction.
[0154] In some specific embodiments, with reference to Figure 1 、 Figure 5 and Figure 7 The penetrating direction of the first mounting hole 122a of the first mounting bracket 120a and the second mounting bracket 120b is parallel to the first direction; with reference to Figure 2 、 Figure 9 、 Figure 10 、 Figure 12 and Figure 13 The penetrating direction of the first mounting hole 122a of the third mounting bracket 120c and the fourth mounting bracket 120d intersects the first direction, so as to adapt to different assembly requirements.
[0155] In some embodiments of the present application, the first mounting hole 122a is configured as one of a round hole and a long hole.
[0156] It can be understood that, in order to meet the assembly, absorb the manufacturing deviation of the device body 110 and the manufacturing tolerance of the power assembly 200, the size of the first mounting hole 122a is calculated according to the size chain tolerance, and the first mounting hole 122a is opened as a round hole or a long hole according to the calculation result of the size chain, so as to meet the assembly requirement on the premise of positioning.
[0157] In some embodiments of the present application, the mounting bracket further comprises a first reinforcing rib (not shown). The first reinforcing rib extends at least from the first fixing part 121 to the first connecting part 122.

[0162] In some specific embodiments, there is a gap between the muffler 111 and the power assembly 200, that is, the muffler 111 is supported on the power assembly 200 by the mounting bracket.
[0163] In some embodiments of the present application, referring to Figures 1 to 4 , the device body 110 further comprises a catalyst 112. The catalyst 112 is used to catalytically treat the exhaust gas, and convert the harmful gases such as CO, HC and NOx in the exhaust gas into harmless carbon dioxide, water and nitrogen gas through oxidation and reduction. The catalyst 112 is connected between the exhaust gas outlet of the power assembly 200 and the muffler 111.
[0164] Specifically, the power assembly 200 comprises an engine, and the catalyst 112 is connected between the exhaust gas outlet of the engine and the gas inlet end of the muffler 111.

[0170] Specifically, the clamp band 131 is sleeved at the connection between the catalyst 112 and the supercharger 240, and the clamp band 131 is clamped by the cooperation of the connecting bolt 132 and the locking nut 133, so as to provide the required axial force and realize the connection and sealing of the catalyst 112 and the supercharger 240.
[0171] In some embodiments of the present application, referring to Figure 1 The central axis C1 of the clamp 130 is perpendicular to the first direction.
[0172] With such a scheme, by limiting the relationship between the central axis C1 of the clamp 130 and the first direction, the complete positioning of the device body 110 can be realized by cooperating the clamp 130 with the mounting bracket.
[0173] In some specific embodiments, the present application realizes the main positioning of the assembly of the device body 110 by the clamp 130 connection between the catalyst 112 and the supercharger 240, which can limit the translation of the device body 110 along the front-rear direction, the left-right direction and the up-down direction, and can limit the rotation of the device body 110 around the front-rear direction and the rotation around the up-down direction.

[0186] In some specific embodiments, the second fixing structure 212a can be a bolt hole provided on the housing 211, and the matching bracket is connected to the housing 211 by bolts.
[0187] In some specific embodiments, the muffler 111 can be supported on the housing 211 only through the matching of the mounting bracket and the matching bracket, or the muffler 111 can be supported on the timing cover 212 only through the matching of the mounting bracket and the matching bracket, or the muffler 111 can be supported on the housing 211 and the timing cover 212 simultaneously through the matching of the mounting bracket and the matching bracket.

[0189] With such a scheme, part of the matching bracket is connected to the housing 211, and the other part of the matching bracket is connected to the timing cover 212, so that the device body 110 maintains a proper distance from the engine to reduce the length of the exhaust pipe between the device body 110 and the engine, while reducing the transmission of engine vibration to the device body 110 and improving the overall modal of the muffler 111. And this scheme can disperse the weight of the device body 110 to the housing 211 and the timing cover 212, reduce the influence of the integration of the device body 110 and the power assembly 200 on the power assembly 200, and at the same time improve the stability of the device body 110.

[0203] In some embodiments of the present application, the second mounting hole 222a is configured as one of a round hole and a long hole.
[0204] It can be understood that, in order to meet the assembly and absorb the manufacturing deviation of the device body 110 and the manufacturing tolerance of the power assembly 200, the size of the second mounting hole 222a needs to be calculated according to the dimension chain tolerance, and the second mounting hole 222a needs to be opened as a round hole or a long hole according to the calculation result of the dimension chain, so as to meet the assembly requirement on the premise of positioning.
