For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0042] The present embodiment relates to an air intake guide structure, which aims to reduce the intake temperature of the engine while cooling the heat dissipation device 4 by optimizing its own structure, thereby improving the performance of the engine.

[0043] In terms of overall structure, the air intake guide structure includes a first guide component 1 arranged in the front engine compartment, and a second guide component 2 located above the first guide component 1. The first guide component 1 is located in front of the heat dissipation device 4 in the front engine compartment, and the second guide component has a vent 2014 arranged corresponding to the air intake of the engine. The first guide component 1 has a main flow channel 101 arranged corresponding to the heat dissipation device 4, and a branch flow channel 109 connected to the main flow channel 101, and the branch flow channel 109 extends toward the second guide component 2, and the airflow in the branch flow channel 109 can enter the air intake of the engine through the vent 2014.

[0044] The intake air guide structure of this embodiment is conducive to guiding the cold airflow to cool the heat sink 4 by providing the main flow channel 101 on the first air guide component 1. And by providing the branch flow channel 109 connected with the main flow channel 101 on the first air guide component 1, it is conducive to guiding the cold airflow to flow directly to the vent 2014, which can reduce the temperature at the vent 2014, thereby reducing the intake air temperature of the engine, thereby improving the performance of the engine and extending the life of the engine.

[0045] Based on the overall introduction above, an exemplary structure of the air intake guide structure in this embodiment is as follows: Figures 1 to 3As shown in . In general, the first air guide component 1 is specifically located between the heat sink 4 and the bumper grille, and the heat sink 4 can be at least one of the radiator, condenser and intercooler in the prior art. The first air guide component 1 is hollow inside to facilitate the formation of the above-mentioned main channel 101. The air inlet of the main channel 101 is located at the front end of the first air guide component 1, and the air outlet of the main channel 101 is located at the rear end of the first air guide component 1. The cold air flows into the first air guide component 1 through the bumper grille, flows to the heat sink 4 through the main channel 101, and flows to the vent 2014 through the branch channel 109.

[0046] In this embodiment, sealing members are provided between the edges of the front end of the first air guide member 1 and the vehicle body, such as sealing sponge strips, to improve the sealing effect between the front end of the first air guide member 1 and the vehicle body, thereby facilitating the increase of the flow rate of the cold air flow into the first air guide member 1. In order to further improve the air intake effect of the cold air flow, Figure 2 and Figure 3 As shown in FIG, an extension portion 102 extending toward the front of the vehicle is provided at the bottom of the first air guide component 1. By providing the extension portion 102, the width of the bottom of the first air guide component 1 is larger, which is beneficial to increase the intake area of ​​the cold air flow, thereby improving the intake efficiency of the cold air flow.

[0047] As a preferred embodiment, Figures 1 to 3 As shown in , the cross section of the main channel 101 is a long strip extending in the left-right direction of the vehicle. Such a configuration is conducive to increasing the air intake area of ​​the cold air flow, thereby improving the cooling effect on the heat sink 4. In addition, in this embodiment, the top of the first air guide component 1 is tilted upward and backward along the direction of the air flow inflow, so that the air outlet area of ​​the main channel 101 is larger than the air inlet area, which is conducive to improving the cooling uniformity of the heat sink 4, thereby improving the cooling effect of the heat sink 4.

[0048] In this embodiment, the first flow guide component 1 has a plurality of connecting flow channels 103 arranged at intervals along the left-right direction of the vehicle, and the branch flow channel 109 is connected to the main flow channel 101 through the plurality of connecting flow channels 103. Here, by providing a plurality of connecting flow channels 103, it is beneficial to increase the gas flow rate flowing to the branch flow channel 109, and further to reduce the temperature at the vent 2014, that is, the engine air intake.

[0049] As a preferred embodiment, the diverter channel 109 is arranged near the end of the main channel 101 in the left-right direction of the vehicle. When the engine is arranged on one side, the diverter channel 109 and the air intake of the engine are arranged at the same end of the main channel 101. When the engine is arranged on both sides, the engine air intakes are respectively arranged at the left and right ends of the main channel 101, and the diverter channel 109 is arranged at both ends of the main channel 101. Such an arrangement is conducive to the cold air flow flowing out of the diverter channel 109 to flow directly to the air intake of the engine through the vent 2014, thereby improving the efficiency of the cold air flow in reducing the temperature at the engine air intake. For example Figure 3 As shown in FIG, the branch channel 109 and the air inlet of the engine are both located at the right end of the main channel 101. In specific implementation, the position of the branch channel 109 and the position of the air inlet of the engine can be set correspondingly.

[0050] In order to further improve the flow effect of the cold air flowing to the branch channel 109, in this embodiment, the first air guide component 1 has an intermediate channel extending in the left-right direction of the vehicle, the intermediate channel is arranged above the air inlet of the main channel 101, and each connecting channel 103 is connected to the branch channel 109 through the intermediate channel. Here, the connecting channel 103 is connected to the branch channel 109 through the intermediate channel, which is conducive to increasing the air flow in the branch channel 109, thereby improving the cooling effect at the air inlet of the engine.

[0051] In terms of specific structure, Figures 1 to 3 As shown in , the first air guide component 1 includes an air guide cover and a baffle assembly 3 arranged on the air guide cover. The main flow channel 101, the branch flow channel 109 and the connecting flow channel 103 are all arranged on the air guide cover, and the air guide cover is provided with a guide groove 1042 extending in the left and right direction of the whole vehicle. The baffle assembly 3 is blocked at the guide groove 1042 and forms an intermediate flow channel with the air guide cover.

[0052] In this embodiment, Figure 6 and Figure 7 As shown in , the notch of the guide groove 1042 is arranged toward the heat sink 4, and the baffle assembly 3 is used to block the notch, thereby facilitating the formation of an intermediate flow channel. Here, by arranging the guide groove 1042 and the baffle assembly 3 on the deflector, it is conducive to forming an intermediate flow channel, thereby improving the air intake and flow guiding effect of the cold air flow. In addition, the baffle assembly 3 can also prevent water from entering the engine through the intermediate flow channel when the vehicle is wading, thereby improving the safety of the engine.

[0053] Still refer to Figure 5As shown in , the baffle assembly 3 is detachably connected to the side of the guide cover facing the heat sink 4. As a structural example, the baffle assembly 3 includes two baffles 301, one of which is longer and the other is shorter. The two baffles 301 cooperate to block the notch of the guide groove 1042, thereby facilitating the formation of the guide groove 1042. In specific implementation, each baffle 301 is detachably connected to the first guide component 1 through the bolts passing through itself and the first guide component 1, and the nuts cooperate with each other.

[0054] When the intake temperature of the engine is too high to meet the use requirements, at least one baffle 301 can be removed, which is beneficial to increase the intake volume of the cold air flow, thereby increasing the flow rate of the cold air flow to the vent 2014. When the intake volume required by the engine is not large, the shorter baffle 301 can be removed. When the intake volume required by the engine is large, the longer baffle 301 can be removed, which is convenient for operation, thereby meeting the use requirements of different intake volumes.

[0055] In addition, the baffles 301 are detachably connected and installed on the first flow guide component 1, which facilitates the individual maintenance and replacement of each baffle 301. Of course, in specific implementation, the number of baffles 301 in the baffle assembly 3 can be adaptively increased or decreased according to usage requirements.

[0056] As a preferred embodiment, Figure 2 and Figure 3 As shown in , the air deflector is provided with a protruding portion 104 protruding forward along the front-rear direction of the vehicle, and the guide groove 1042 is provided in the protruding portion 104. The protruding portion 104 is located at the top of the air inlet and extends in the left-right direction of the vehicle, and the guide groove 1042 is provided on the side of the protruding portion 104 facing the heat dissipation device 4. Here, by providing the protruding portion 104 on the first air guide component 1 and providing the guide groove 1042 in the protruding portion 104, it is beneficial to improve the structural strength of the middle flow channel.

[0057] In addition, if Figure 3 and Figure 6As shown in , there are four connecting flow channels 103 arranged at intervals at the bottom of the middle flow channel along the left-right direction of the whole vehicle. In order to facilitate the formation of the connecting flow channel 103 on the first air guide component 1, a plurality of protrusions 1031 protruding toward the front end of the vehicle are provided below the protruding portion 104, and each protrusion 1031 is provided with a connecting groove extending through the height direction of the whole vehicle, and the notch of the connecting groove is arranged toward the heat dissipation device 4, and each connecting flow channel 103 is formed between the bottom of the baffle assembly 3 and the connecting groove. This is conducive to the cold air flow in the main channel 101 flowing upward into each connecting flow channel 103, and then flowing through the middle flow channel and the branch channel 109 in turn and then flowing out from the vent 2014. It can be understood that the number of connecting flow channels 103 can also be adaptively increased or decreased according to the use requirements.

[0058] Furthermore, the middle flow channel is provided with reinforcing ribs 1041 arranged in the vertical direction of the vehicle, and the reinforcing ribs 1041 are arranged at intervals along the airflow direction in the middle flow channel. By providing a plurality of reinforcing ribs 1041 arranged in the vertical direction of the vehicle in the middle flow channel, it is beneficial to improve the structural strength of the middle flow channel in the vertical direction of the vehicle.

[0059] like Figure 6 and Figure 7 As shown in , the reinforcing rib 1041 is in the guide groove 1042, and the reinforcing rib 1041 can divide the middle flow channel into a plurality of connected parts, and each reinforcing rib 1041 is provided with a connecting port that connects two adjacent connected parts, so as to ensure that the cold air flow flowing into the middle flow channel can flow into the branch flow channel 109. Due to the setting of the connecting port, the reinforcing rib 1041 is in a U shape with the opening facing backward, and is respectively connected to the top arm, bottom wall and groove bottom of the guide groove 1042, so as to have good connection strength. In specific implementation, the structural form, quantity and position of the reinforcing rib 1041 can also be adjusted according to the use requirements.

[0060] As a preferred embodiment, Figure 2 As shown in the figure, the top surface of the front end of the first guide member 1 is a downwardly inclined inclined surface 105, and the connecting flow channel 103 is arranged between the inclined surface 105 and the protruding portion 104. Here, the top surface of the first guide member 1 is the inclined surface 105, and the connecting flow channel 103 is arranged between the inclined surface 105 and the protruding portion 104, which is convenient for the front end of the vehicle to collapse when colliding, thereby improving the protection of pedestrians.

[0061] Furthermore, two gaps 1051 are arranged at intervals at both ends of the top of the first guide component 1. The gaps 1051 are provided to facilitate the collapse effect of the first guide component 1, thereby facilitating the collapse effect of the front end top of the first guide component 1, thereby improving the safety of the front cabin.

[0062] like Figures 1 to 3As shown in , the second air guide component 2 includes a first split body 201 and a second split body 202 disposed at the left and right ends of the first air guide component 1, and an escape space is formed between the first split body 201 and the second split body 202, and the escape space is used to escape the hood lock. Here, the installation method of the first split body 201 and the second split body 202 is easy to arrange and implement, and is conducive to the installation of the hood lock. Of course, in addition to setting the first split body 201 and the second split body 202 as a split structure, the second air guide component 2 can also be set as an integral molding. In this case, the above-mentioned escape space still needs to be formed on the second air guide component 2.

[0063] As a layout method, such as Figure 6 As shown in , the first air guide component 1 is provided with an air guide plate 108 located at the outlet of the flow diversion channel 109, and the air guide plate 108 extends toward one side of the heat sink 4. The first split body 201 is provided with the above-mentioned vent 2014, and the first split body 201 is provided at the outlet, and has a vent plate 2012 located above the air guide plate 108, and the vent 2014 is provided on the vent plate 2012. Here, the air guide plate 108 extends toward one side of the heat sink 4, and the vent plate 2012 is provided above the air guide plate 108, which is conducive to guiding the cold air flow to flow into the engine, further improving the air intake efficiency of the engine.

[0064] In terms of detailed structure, the first split body 201 is located at the right end of the first flow guide component 1, and the second split body 202 is located at the left end of the first flow guide component 1. Of course, consistent with the arrangement principle of the flow diversion channel 109, the vent 2014 is specifically arranged on the first split body 201 and / or the second split body 202, which is also determined based on the arrangement position of the engine. For example, when the engine is arranged on one side, the vent 2014 is arranged on the split body arranged at the same end as the air inlet of the engine. When the engine is arranged on both sides, the vent 2014 is respectively arranged on the first split body 201 and the second split body 202.

[0065] Combination Figure 8 and Fig. 9 As shown in , the first split body 201 in this embodiment has a main body 2011 extending along the height direction of the vehicle, the ventilation plate 2012 is connected to the top of the main body 2011 and extends to the rear of the vehicle, and a mounting plate 2013 extending to the front end of the vehicle is provided at the bottom of the main body 2011. The top ends of the first split body 201 and the second split body 202 can also provide a mounting base for the installation of peripheral components of the front cabin.

[0066] like Figure 8As shown in the figure, a concave groove 2015 is provided on the ventilation plate 2012, and the groove 2015 is open to one side of the heat dissipation device 4. The vents 2014 in this embodiment are multiple and are provided on the peripheral walls of each side of the groove 2015, which is conducive to improving the air outlet efficiency of the cold air flow. Preferably, the vents 2014 are in the shape of a long strip extending along the height direction of the vehicle, and the width of the bottom of the vents 2014 is greater than the width of the top, which is conducive to improving the outflow effect of the cold air flow, and the structure of the vents 2014 is simple and easy to process and shape.

[0067] In this embodiment, the groove 2015 is the air intake area of ​​the engine air intake port, and the cold air flow from each vent 2014 can be mixed with the nearby hot air flow in the air intake area, thereby reducing the air flow temperature in the air intake area, which is beneficial to reducing the intake temperature of the engine. It should be noted that the size of the vent 2014 in this embodiment is adapted to the cross-sectional area of ​​the engine intake pipe inlet to meet the intake volume of the engine per unit time.

[0068] In order to improve the structural strength of the first sub-body 201 and the second sub-body 202, multiple reinforcing ribs 1016 arranged at intervals are provided on both. For example, multiple reinforcing ribs 1016 are provided on both the front and rear sides of the main body 2011, and some of the reinforcing ribs 1016 are extended along the height direction of the whole vehicle, which is conducive to improving the strength of the sub-body in the height direction of the whole vehicle and has better performance. In addition, multiple reinforcing ribs 1016 located on the rear side of the main body 2011 are extended along the up and down direction of the whole vehicle, which is not only conducive to improving the structural strength of the first sub-body 201, but also allows the cold air flow to flow to the vent 2014 better, thereby achieving a better diversion effect.

[0069] Furthermore, in this embodiment, the first air guide component 1 is installed in the front cabin through the second air guide component 2. Figure 6 As shown in the figure, first mounting points 107 for connecting with the second flow guide component 2 are respectively provided on both sides of the bottom of each main body part 2011. As a structural example, the first mounting point 107 includes a plurality of first mounting holes provided on the first flow guide component 1, and first matching holes corresponding to the first mounting holes are provided on the second flow guide component 2. The first flow guide component 1 and the second flow guide component 2 are connected together by the bolts passing through the first mounting holes and the corresponding first matching holes and the nuts. In addition to the bolt connection, the first flow guide component 1 and the second flow guide component 2 in this embodiment can also be connected by a snap fastener.

[0070] In addition, if Figure 5As shown in the figure, the left and right sides of the first air guide component 1 are respectively provided with second mounting points 106 for connecting with the heat sink 4. For example, the second mounting point 106 can be a second mounting hole, and a second matching hole corresponding to the second mounting hole is provided on the heat sink 4. The first air guide component 1 and the heat sink 4 are connected together by screwing the bolts passing through the second mounting holes and the corresponding second matching holes and the nuts.

[0071] like Figure 5 and Figure 6 As shown in , a third mounting point 1022 for connecting to the heat sink 4 is provided on one of the extension parts 102. In specific implementation, the third mounting point 1022 can be a connector, and a connection hole for inserting the connector is provided on the heat sink 4, where the connector can also play a role in positioning and installation. Furthermore, a fourth mounting point 1021 for connecting to the leg anti-collision beam is provided at the bottom of each extension part 102.

[0072] The flow path of the airflow in the air intake guide structure of this embodiment is as follows: Figure 4 As shown in FIG, most of the cold air flow flowing into the main flow channel 101 flows directly to the heat sink 4 and cools the heat sink 4. A small portion of the cold air flow flows into the middle flow channel through the plurality of connecting flow channels 103, and flows into the branch flow channel 109 via the middle flow channel. The cold air flow flows to the vent 2014 via the branch flow channel 109, and the cold air flow is mixed with the hot air flow flowing back from the heat sink 4 at the vent 2014, thereby reducing the intake temperature of the engine.

[0073] In addition, the air intake guide structure is also beneficial to reduce the wind resistance of the whole vehicle, thereby reducing fuel consumption. It has been verified that the air intake guide structure in this embodiment can reduce the engine's intake temperature by an average of 2.7°C, reduce the wind resistance of the whole vehicle by 0.009cd, and reduce fuel consumption by 0.18L / 100km.

[0074] In addition, the present embodiment also relates to a vehicle, in which the air intake guide structure as described above is provided.

[0075] The vehicle of this embodiment can improve the use efficiency of the engine by providing the air intake guide structure as described above, thereby enhancing the power performance of the vehicle.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
