Description

Technical Field

[0001] The utility model relates to the technical field of vehicle manufacturing, in particular to an engine component and a vehicle with the engine component. Background Art

[0002] As vehicles become more and more important in daily life, lightweight design of vehicles is also an issue that needs to be considered in the vehicle manufacturing process. The miniaturization of engines has become the goal pursued by various OEMs, and the most direct way to miniaturize engines is to reduce the length of the entire machine. The mainstream way to reduce the length of the entire machine is to place the traditional intake intercooler placed at the front end of the engine on the upper part of the engine cylinder to form a separate support structure, which is installed above the fastening bolts of the cylinder head or cylinder block, thereby achieving the goal of reducing the longitudinal length of the entire machine.

[0003] However, after the intercooler is placed from the front end of the engine to the upper part of the engine cylinder, the intercooler will exert a downward force on the supporting structure during vehicle driving. In order to increase the structural strength of the supporting structure, a larger support structure is often used for support. However, a larger supporting structure is not conducive to the lightweight design of the vehicle. In addition, an overly large supporting structure causes greater vibration and radiation noise after it is connected to the engine, which is more likely to cause more serious NVH problems. There is room for improvement. Utility Model Content

[0062] This can effectively ensure that the intercooler 3 is in a horizontal state when the engine is mounted on the vehicle, effectively reducing the vibration response and radiation noise of the intercooler 3. At the same time, the intercooler 3 can be in a high point state, effectively reducing the accumulation of cooling water, thereby avoiding the occurrence of problems such as ice in winter and ensuring the operational reliability of the intercooler 3.

[0063] In some embodiments, the first mounting plate portion 41 and / or the second mounting plate portion 42 is provided with at least one weight-reducing groove 44 and / or weight-reducing hole 45; the depth of the weight-reducing groove 44 is set to L, and satisfies: L≥1 mm.

[0064] Specifically, Figure 3-Figure 5 As shown, the first mounting plate portion 41 and / or the second mounting plate portion 42 are provided with at least one weight reducing groove 44 and / or weight reducing hole 45, that is, one of the first mounting plate portion 41 and the second mounting plate portion 42 may be provided with a weight reducing groove 44 or a weight reducing hole 45, and one of the first mounting plate portion 41 and the second mounting plate portion 42 may also be provided with both the weight reducing groove 44 and the weight reducing hole 45, and the first mounting plate portion 41 and the second mounting plate portion 42 may also be both provided with the weight reducing groove 44 or the weight reducing hole 45, and the first mounting plate portion 41 and the second mounting plate portion 42 may also be both provided with the weight reducing groove 44 and the weight reducing hole 45.

[0065] Furthermore, in the present embodiment, the first mounting plate portion 41 is provided with a weight-reducing groove 44, and a weight-reducing hole 45 is provided in the weight-reducing groove 44, and reinforcing ribs 46 are formed between the plurality of weight-reducing grooves 44; the second mounting plate portion 42 is only provided with a weight-reducing groove 44, and reinforcing ribs 46 are formed between the weight-reducing grooves 44; the depth of the weight-reducing groove 44 is set to L, and the depth L of the weight-reducing groove 44 satisfies: L ≥ 1 mm, that is, the depth L of the weight-reducing groove 44 can be set to 1 mm, etc., which can effectively reduce the weight of the mounting bracket 4 while ensuring the structural strength of the mounting bracket 4, wherein the weight-reducing hole 45 is located in the middle part of the mounting bracket 4 where the strength is less affected, and at the same time, the weight-reducing groove 44 and the weight-reducing hole 45 can also effectively suppress the problem that the large plane structure is prone to resonance, improve the end mode of the cylinder head 1, effectively reduce the vibration response and radiation noise of the mounting bracket 4, and improve the NVH performance.

[0066] The utility model also provides a vehicle.

[0067] The vehicle according to the embodiment of the utility model is provided with any one of the above-mentioned engine components.

[0068] According to the vehicle of the embodiment of the utility model, an engine assembly is provided, and the engine assembly is provided with a first mounting plate portion 41 and a second mounting plate portion 42 connected to each other. The intercooler 3 is installed above the engine and can be partially connected to the engine through the second mounting plate portion 42, thereby improving the reliability of the connection between the intercooler 3 and the engine, and reducing the vibration and radiation noise generated after the intercooler 3 is installed on the engine, thereby ensuring the NVH performance of the vehicle. The mounting bracket 4 has a simple structure, which can ensure the lightweight of the vehicle, better use effect, and a wider range of applications.
