It should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings. Without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0058] Combined Figure 1 and Figure 13 , the engine control unit assembly disclosed by the present invention includes an engine control unit 100, a bracket assembly and a shield 200; the engine control unit 100, the bracket assembly and the shield 200 are all arranged in the engine compartment of the vehicle; the bracket assembly is used to connect with the engine front panel assembly 500 and / or the engine compartment right wheel housing panel assembly 510; the shield 200 is connected with the bracket assembly, and a receiving space is formed between the shield 200 and the bracket assembly, the engine control unit 100 is connected with the bracket assembly and arranged in the receiving space, the shield 200 is made of heat-insulating and magnetic-isolating materials and can play a role in dust prevention.

[0059] The engine control unit 100 is usually also called an engine control module, which is an electronic control unit used to control a series of actuators on the engine to ensure the best engine performance. The specific structure and function of the engine control unit 100 are both prior arts and will not be elaborated here.

[0060] The shield 200 is made of a material with good electromagnetic interference resistance and heat insulation performance. Exemplarily, it can be DC01 material, which can isolate the electromagnetic interference in the engine compartment. At the same time, the shield 200 can also block the heat radiation in the engine compartment and reduce the temperature on the surface of the engine control unit 100.

[0061] Furthermore, the shield 200 is prepared from a material with a relatively low density to meet the lightweight requirements of the vehicle.

[0062] Compared with the prior art, the engine unit control assembly disclosed in the present utility model is arranged in the engine compartment. When a component of the engine control unit 100 is damaged, the engine control unit 100 can be disassembled only by removing the bracket assembly from the engine compartment, and the disassembly and repair are convenient; and the structure is simple, the production is convenient, and the cost is low; the electromagnetic interference and high temperature influence in the engine compartment are effectively reduced through the setting of the shield 200. The engine unit control assembly disclosed in the present utility model can be pre-assembled and formed, and finally installed on the vehicle, saving the assembly time.

[0063] In the present utility model, in combination with Figures 1-4 , the connection manners between the engine control unit 100, the shield 200 and the bracket assembly can be fixed connection manners such as welding, bonding, bolt fixed connection, clamping, riveting, etc., and no specific limitation is imposed herein.

[0064] In an embodiment, an identification part 101 is arranged on the engine control unit 100. The identification part 101 is used to record the relevant information of the engine control unit 100, which is convenient for parts tracking, information recording, after-sales control, etc. Exemplarily, a two-dimensional code can be pasted on the identification part 101. In order to avoid the influence of the shield 200 on the identification process of the identification part 101, in combination with Figure 3 and Figure 4 , a through avoidance hole 201 is formed in the shield 200. The avoidance hole 201 corresponds to the identification part 101 on the engine control unit 100, so as to facilitate the later traceability according to the identification part 101.

[0065] In another embodiment, the setting position of the identification part 101 is arranged towards the bracket assembly, and a corresponding avoidance hole 201 for avoiding the identification part 101 is arranged on the bracket assembly.

[0066] The shape of the above avoidance hole 201 is not limited, as long as it can ensure that the identification part 101 can be recognized. Exemplarily, the avoidance hole 201 can be a square hole.

[0067] In a specific embodiment disclosed in the present utility model, in combination with Figure 1, the engine control unit assembly is integrated with a nitrogen oxide sensor 400, and the nitrogen oxide sensor 400 is used to monitor the content of nitrogen oxides in the exhaust gas. Combining Figure 1 , the nitrogen oxide sensor 400 is arranged on the side of the shield 200 facing away from the engine control unit 100, and the nitrogen oxide sensor 400 is arranged outside the accommodating space. By integrating the nitrogen oxide sensor 400, the structure in the engine compartment can be made more compact.

[0068] Specifically, combining Figures 11-12 , the nitrogen oxide sensor 400 is arranged on the shield 200 through a sensor bracket 410. In one embodiment, the sensor bracket 410 includes a connecting plate 411 and a column 412; the first side of the connecting plate 411 is attached to and connected to the shield 200; the columns 412 are multiple and arranged on the second side of the connecting plate 411, and a fixing space is formed between the columns 412. A buckle 413 is arranged at one end of the column 412 away from the connecting plate 411, and the nitrogen oxide sensor 400 is arranged in the fixing space and is provided with a slot 401 for the buckle 413 to be embedded.

[0069] In order to reliably fix the nitrogen oxide sensor 400 in the fixing space, combining Figure 11 , a pressing protrusion 414 abutting against the nitrogen oxide sensor 400 is arranged on the second side of the connecting plate 411. When the nitrogen oxide sensor 400 is installed in the fixing space, the column 412 and the pressing protrusion 414 cooperate and press the nitrogen oxide sensor 400 from two opposite directions respectively, realizing the reliable fixation of the nitrogen oxide sensor 400 and the sensor bracket 410.

[0070] Combining Figure 1 、 Figure 4 and Figure 11 , the connecting plate 411 is bolted to the shield 200. A first connecting hole 202 is arranged on the shield 200, and a third connecting hole 415 is arranged on the connecting plate 411. The bolt passes through the first connecting hole 202 and the third connecting hole 415 and is tightened by a nut. Specifically, combining Figure 3 , the first connecting hole 202 is arranged on a boss formed by stamping the shield 200 on the side away from the engine control unit 100. The setting of the boss is used to accommodate the bolt and the nut, thereby avoiding interference between the fixation of the sensor bracket 410 and the engine control unit 100.

[0071] Since the size of the sensor bracket 410 is small, the number of the third connecting holes 415 can be two and are arranged diagonally on the connecting plate 411.

[0072] Combining Figure 1 , the bracket assembly is used to reliably fix the engine control unit 100 in the engine compartment to prevent the vibration of the engine control unit 100 from affecting its normal function.

By connecting the first mounting bracket 300 and the second mounting bracket 310 to the right wheelhouse panel assembly 510 of the engine compartment and the engine front bulkhead assembly 500 respectively, the fixed points of the engine control unit 100 in the engine compartment can be effectively increased, thereby improving the reliability of the fixed position of the engine control unit assembly and reducing the probability of vibration.

[0073] Among them, the first mounting bracket 300 is mainly used to connect to the shield 200 and fix the engine control unit 100, and the first mounting bracket 300 is fixed on the right wheelhouse panel sub-assembly 511 of the right wheelhouse panel assembly 510 of the engine compartment. The second mounting bracket 310 is in a long strip shape and is mainly used for long-distance connection and fixation between the first mounting bracket 300 and the engine front bulkhead assembly 500.

[0074] Specifically, the connection method between the first mounting bracket 300 and the second mounting bracket 310 can be fixed connection methods such as welding, bonding, bolt fixed connection, clamping, riveting or integral molding, etc., and there is no specific limitation here. Preferably, the first mounting bracket 300 and the second mounting bracket 310 are of a split structure and are detachably connected by bolts, which is convenient for disassembly and assembly.

[0075] In a specific embodiment disclosed by the present utility model, the first mounting bracket 300 includes a side plate 301 and a bottom plate 302; the first side of the side plate 301 is connected to the shield 200 and forms an accommodation space, and the engine control unit 100 is connected to the first side of the side plate 301.

[0076] Usually, the first connecting ear 305 is vertically arranged with the side plate 301, which is convenient for the connection of the second mounting bracket 310, and the second mounting bracket 310 can be bent to a certain extent according to the specific connection conditions in the engine compartment. Combining Figure 8 , second connecting holes 312 are opened at both ends of the second mounting bracket 310 to be bolt-connected to the first connecting ear 305 and the engine front bulkhead assembly 500 respectively. The side plate 301 and the bottom plate 302 are usually of an integral structure and are prepared by bending.

[0077] For a further optimized solution, the first mounting bracket 300 further includes side vertical plates 303. There are two side vertical plates 303 symmetrically arranged on the second side of the side plate 301, and the side vertical plates 303 are arranged at an angle to the side plate 301. Usually, the side vertical plates 303 are arranged perpendicular to the side plate 301. Combining with Figure 7 , the main body of the side vertical plate 303 is in the shape of a triangular plate for support. A second connecting ear 304 for bolt connection with the right wheel housing panel assembly 510 of the engine compartment can also be provided on the side vertical plate 303.

[0078] The side plate 301 and the side vertical plate 303 are usually of an integral structure and are prepared by bending.

[0079] In order to effectively reduce the structural weight, combining with Figure 7 , without affecting the structural strength, weight reduction holes can be opened on the side plate 301 and the side vertical plate 303.

[0080] In order to effectively reduce the mass of the engine control unit assembly without affecting the anti-electromagnetic interference and heat insulation performance of the shield 200, the engine control unit 100 includes a control component and a housing. The control component is arranged inside the housing, and the housing is arranged in the accommodation space and is connected to the side plate 301; along the direction of the side plate 301 towards the shield 200, the projection of the control component coincides with the projection of the shield 200, and the projection area is less than or equal to the projection area of the shield 200, that is, along the direction of the side plate 301 towards the shield 200, the control component completely falls within the protection range of the shield 200, so as to maximize the utilization of the protection performance of the shield 200 and reduce the redundant structure of the shield 200.

[0081] The vehicle disclosed by the present utility model includes an engine compartment, a front engine bulkhead assembly 500, a right wheel housing panel assembly 510 of the engine compartment, an air filter assembly 520, and the above-mentioned engine control unit assembly.

When the outside air flow enters the interior of the engine compartment, the air flow first passes through the filtration and blockage of the air filter assembly 520, and then flows to the engine control unit assembly and other positions in the engine compartment, so as to reduce the influence of dust and moisture in the air entering through the front grille of the whole vehicle on the engine control unit assembly. The shield 200 is arranged facing the air filter assembly 520, which can further prevent the surface of the engine control unit 100 from being contaminated by impurities such as dust in the air. In addition, the arrangement position of the engine control unit assembly is close to the air flow path, and the ambient temperature is lower, which can prevent the engine control unit 100 from overheating and reduce the heat dissipation cost.
