[0031] Preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the scope of protection of the present application.

[0032] First, it should be noted that the orientation terms such as top, bottom, upward, downward, etc. mentioned herein are defined with respect to the directions in each of the accompanying drawings. These orientations are relative concepts and will therefore vary according to their positions and states. Therefore, these or other orientation terms should not be construed as restrictive.

[0033] In addition, it should also be pointed out that for any single technical feature described or implied in the embodiments herein or any single technical feature shown or implied in the accompanying drawings, these technical features (or their equivalents) can continue to be combined to obtain other embodiments not directly mentioned herein.

[0034] It should be noted that in different accompanying drawings, the same reference numerals denote the same or substantially the same components.

[0035] Figures 1 to 4 Shows different aspects of the sensor bracket 10 of the present application. The sensor bracket 10 may include: a body 100, a plurality of buckles 200, a plurality of stoppers 300, etc. In one embodiment, the sensor bracket 10 may be an integrally formed component. In one embodiment, the sensor bracket 10 may be made of plastic or plastic reinforced with metal.

[0036] The body 100 may have a generally plate-shaped structure and may provide support for other components and structures. In one embodiment, the body 100 may include one or more mounting holes 101 for fixing the sensor bracket 10 to a predetermined position.

[0037] The buckle 200 can extend from the body 100. In one embodiment, the buckle 200 may include: a connecting portion 210, a vertically extending portion 220, a first reinforcing rib 230, etc. The connecting portion 210 may include a first section 211 and a second section 212. The first section 211 and the second section 212 may be a continuous structure and form a predetermined angle with each other. In the illustrated embodiment, the second section 212 may be substantially parallel to the body 100, the first section 211 may extend from the body 100, and the predetermined angle may be between 110 degrees and 150 degrees, such that the first section 211 is non-vertical with respect to the body 100. Such a structure helps to provide structural flexibility to the buckle 200 and avoid local warping due to thermal expansion and contraction during molding.

[0038] The vertically extending portion 220 can extend from the end of the connecting portion 210 and extend perpendicular to the body 100. The top of the vertically extending portion 220 may include a hook 221, and the outer contour of the hook 221 may form an inwardly concave rounded contour 222. Such a rounded contour structure can reduce stress concentration and fracture failure and improve the durability of the component. The rounded contour 222 may have a predetermined diameter. In one embodiment, the predetermined diameter may be between 0.25 mm and 0.5 mm. For example, the predetermined diameter may be 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, or 0.5 mm. The hook 221 may be shaped to hold a sensor (not shown). For example, a plurality of hooks 221 may cooperate to hold and fix the sensor from different directions.

[0039] The first reinforcing rib 230 may be provided between the vertically extending portion 220 and the second section 212. For example, the first reinforcing rib 230 may be a structure that tapers from bottom to top. Such a structure is beneficial for demolding on the one hand and for improving the structural strength of the entire buckle 200 on the other hand. In one embodiment, each buckle 200 may include one first reinforcing rib 230. The first reinforcing rib 230 may be positioned at the bottom of the buckle 200.

[0040] The structure of the buckle 200 can effectively reduce the stress concentration on the buckle 200 and significantly reduce the value of the maximum stress.

[0041] The stop portion 300 may include: a base portion 310, a constricted portion 320, a top portion 330, etc. The base portion 310 may extend vertically from the body 100. The constricted portion 320 may extend from the top of the base portion 310 and have a tapered outer contour to form an inclined surface 321. As Figure 4As shown, the inclined surface 321 can form a certain angle relative to the surface of the main body 100. The top 330 can extend from the top of the constriction 320 and extend perpendicularly relative to the surface of the main body 100. In one embodiment, the side surface 331 of the top 330 can have a planar shape, and the side surface 331 and the inclined surface 321 can be arranged adjacent to each other. The stopper 300 can be provided with one or more second reinforcing ribs 340. The second reinforcing ribs 340 can be arranged on the side of the stopper 300 opposite to the side surface 331 and the inclined surface 321.

[0042] Such a structure of the stopper 300 is designed to make the side surface 331 and the inclined surface 321 abut against the outer surface of a sensor (not shown) together. For example, the side surface 331 and the inclined surface 321 can abut against the outer surface of the sensor together, so that the force transmitted from the sensor to the stopper 300 remains perpendicular to the side surface 331, that is, generally remains in the horizontal direction.

[0043] In addition, each stopper 300 can be arranged adjacent to each buckle 200. In one embodiment, one or more stoppers 300 and one or more buckles 200 can be respectively arranged on both sides of the sensor. The stoppers 300 and the buckles 200 on both sides of the sensor can be aligned with each other or arranged in a staggered manner. In the illustrated embodiment, three stoppers 300 are arranged on the main body 100, two of the stoppers 300 are arranged on the left side of the main body 100, and one stopper 300 is arranged on the right side of the main body 100. According to other embodiments, the stopper 300 can also be arranged at any other suitable position and an appropriate number of stoppers 300 can be provided.

[0044] This application also relates to an exhaust system. The exhaust system can include a sensor and the sensor bracket 10 described above; the sensor can be mounted on the sensor bracket 10. For example, the sensor can be clamped by the hooks 220 of a plurality of buckles 200, and a plurality of stoppers 300 can be positioned to abut against the outer surface of the sensor. In one embodiment, the sensor can be a nitrogen oxide sensor and is used to sense the content of nitrogen oxides in the vehicle exhaust.

[0045] This application also relates to a vehicle. The vehicle can include an engine and the exhaust system described above. The sensor bracket 10 described above can be mounted on the engine. In one embodiment, the sensor bracket 10 described above is used to mount a nitrogen oxide sensor.

[0046] The sensor bracket, exhaust system and vehicle of this application have the advantages of being simple and reliable, easy to implement, convenient to use, etc., and can provide improved clamping ability, improve the clamping reliability of the sensor, and at the same time improve the robustness and durability in the actual working conditions of the vehicle.
