Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a fairing, a vehicle front compartment assembly and a vehicle. BACKGROUND

[0002] The main function of the front compartment fairing structure is to block the wind from the left and right sides and prevent the cooling airflow from escaping from the left and right sides. When this structure is applied to a hybrid vehicle, an upper and lower air inlet grille needs to be provided at the same time, so that sufficient cooling airflow can be ensured above the radiator. However, as people's requirements for the appearance and reduction of automobile resistance are becoming higher and higher, it is inevitable for the automobile industry to develop a hybrid vehicle with only a lower grille.

[0003] However, the hybrid vehicle has high heat dissipation requirements, and the coolant often enters from the top of the radiator and flows out from the bottom. In order to fully dissipate the heat of the coolant, more cooling airflow needs to be guided to the top of the radiator while only the lower grille is provided. A fully enclosed fairing can meet this requirement. However, there are still problems in the application of the current fully enclosed fairing. For example, when arranging the fully enclosed fairing, the front bumper beam needs to be bypassed or wrapped. Both of these two processing methods need to ensure that there is a certain gap between the fairing and the front bumper beam. The gap and the thickness of the fairing itself occupy the arrangement space of the front compartment in the front-rear direction of the vehicle, which makes the design freedom of the front compartment not high and the arrangement flexibility not enough.

[0063] 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 those skilled in the art without creative labor fall within the protection scope of the present application.

[0064] Please refer to Figure 1 , the present application provides a vehicle 1000, the vehicle 1000 includes an air deflector 100 or a vehicle front compartment assembly 1100.

[0065] Please refer to Figures 2 to 8 , the vehicle front compartment assembly 1100 includes the air deflector 100 and the front anti-collision beam 200, and the air deflector 100 is connected to the front anti-collision beam 200.

[0066] In some embodiments of the present application, the vehicle front compartment assembly 1100 further comprises an air outlet cover 300 connected to the air outlet cover 300, the air outlet cover 300 having an air outlet cavity 31 communicating with the air inlet channel of the engine (not shown in the figure).

[0067] In some embodiments of the present application, the vehicle front compartment assembly 1100 further comprises a front end frame upper assembly 400 connected to the air inlet cover 100 and the air outlet cover 300.

[0068] In some embodiments of the present application, the vehicle front compartment assembly 1100 further comprises a front end frame lower assembly 500 connected to the air inlet cover 100.

[0069] In some embodiments of the present application, the vehicle front compartment assembly 1100 further comprises a heat dissipation assembly 600 connected to the air inlet cover 100.

[0070] Specifically, referring again to Figure 2 and Figure 8 , the air inlet cover 100 comprises a first sub-air inlet cover 1 and a second sub-air inlet cover 2, the second sub-air inlet cover 2 is separately arranged from the first sub-air inlet cover 1, and the first sub-air inlet cover 1 and the second sub-air inlet cover 2 are located on both sides of the front crash beam 200 of the vehicle 1000 along the first direction and are connected to the front crash beam 200.

[0071] The air inlet cover, the vehicle front compartment assembly 1100 and the vehicle 1000 provided by the present application, the air inlet cover comprises a first sub-air inlet cover 1 and a second sub-air inlet cover 2, the second sub-air inlet cover 2 is separately arranged from the first sub-air inlet cover 1, and the first sub-air inlet cover 1 and the second sub-air inlet cover 2 are located on both sides of the front crash beam 200 of the vehicle 1000 along the first direction and are connected to the front crash beam 200. The present application divides the air inlet cover into the first sub-air inlet cover 1 and the second sub-air inlet cover 2, and connects the first sub-air inlet cover 1 and the second sub-air inlet cover 2 by using the structure (front crash beam 200) of the vehicle itself, realizes the upper and lower split of the air inlet cover, saves the material of the air inlet cover, and reduces the gap between the air inlet cover and the front crash beam 200, thereby reducing the space occupied by the air inlet cover in the front-rear direction of the vehicle, making the front compartment design degree of freedom high and the arrangement more flexible.

[0072] In some embodiments of the present application, the first sub-air inlet cover 1 and / or the second sub-air inlet cover 2 are respectively connected to the front crash beam 200, so as to realize the full closure of the airflow and obtain a full-closed air inlet cover, so that the air inlet cover 100 of the present application can be applied to a hybrid vehicle, and more cooling airflow can be guided to the upper side of the heat dissipation assembly (corresponding to the first sub-air inlet cover 1) while only one grille (lower grille, corresponding to the second sub-air inlet cover 2) is opened, thereby meeting the high heat dissipation demand of the hybrid vehicle.

[0073] In the embodiment, the first sub-guide cover 1 and / or the second sub-guide cover 2 are respectively sealedly connected with the front bumper beam 200 through sealing cotton.

[0074] In some embodiments of the present application, the vehicle front compartment assembly 1100 further comprises two first sealing members 840, which are located on two sides of the guide cover 100 in a second direction X intersecting the first direction Z and are respectively sealedly connected with the first sub-guide cover 1, the second sub-guide cover 2 and the front bumper beam 200. That is, the two first sealing members 840 are sealed in the gaps between the first sub-guide cover 1, the second sub-guide cover 2 and the left and right sides of the front bumper beam 200. In this way, it is beneficial to achieve full sealing of the airflow and obtain a full-sealing guide cover.

[0075] In some embodiments of the present application, the first sub-guide cover 1 and / or the second sub-guide cover 2 are respectively detachably connected with the front bumper beam 200, which is beneficial for disassembly.

[0076] In the embodiment, the first sub-guide cover 1 and / or the second sub-guide cover 2 are respectively snap-fitted with the front bumper beam 200.

[0077] In some embodiments of the present application, the first sub-guide cover 1 has a first guide cavity 10, which is communicated with an air inlet passage of an engine of the vehicle 1000 through an air outlet cavity 31. The second sub-guide cover 2 has a second guide cavity 20, which is communicated with an air inlet of an air inlet grille (not shown) of the vehicle 1000. The first guide cavity 10 and the second guide cavity 20 are communicated. In this way, part of the airflow flowing into the second guide cavity 20 from the air inlet of the air inlet grille can flow into the first guide cavity 10 from the second guide cavity 20, and flow into the air inlet passage of the engine from the first guide cavity 10, thereby meeting the air intake requirement of the engine.

[0078] In some embodiments of the present application, the second sub-ventilator 2 comprises a ventilator main body part 25 and a ventilator part 26, the ventilator main body part 25 has the second ventilator cavity 20, and the ventilator part 26 is close to the air inlet grille and located on the side of the ventilator main body part 25 away from the first sub-ventilator 1; the ventilator part 26 comprises a first ventilator surface 261, and the first ventilator surface 261 has a connection end 2611 connected with the ventilator main body part 25 and a free end 2612 away from the connection end. Among them, the first ventilator surface 261 is inclined relative to the first direction Z, and the shortest distance from the connection end 2611 of the first ventilator surface 261 to the first sub-ventilator 1 is greater than the shortest distance from the free end 2612 of the ventilator surface to the first sub-ventilator 1. That is, the first ventilator surface 261 is not parallel but obliquely inclined, and there is a certain angle between the first ventilator surface 261 and the horizontal plane. This design is mainly to make more cooling airflow flow to the upper part of the heat dissipation assembly 600, and better meet the heat dissipation requirement. When the first ventilator surface 261 adopts the inclined design, the cooling airflow flowing through has a certain vertical upward component, which can play a certain flow guiding role. The present application utilizes the structure (first ventilator surface 261) of the second sub-ventilator 2 itself to guide the flow, without the need to increase additional structural members to achieve gas guiding, thereby effectively reducing the cost.

[0079] In some embodiments of the present application, the second ventilator cavity 20 comprises an inlet end 21 facing the air inlet grille and an outlet end 22 away from the air inlet grille; wherein from the inlet end 21 to the outlet end 22, the size of the second ventilator cavity 20 along the first direction first gradually decreases and then gradually increases. The inlet of the second ventilator cavity 20 adopts a tapered design mainly to increase the flow rate of the cooling airflow, and better play a cooling and heat dissipation role. The outlet of the second ventilator cavity 20 adopts a gradually expanding design, which is connected with the lower assembly 500 of the front frame on one hand, and realizes the sealing of the bottom of the second sub-ventilator 2 by utilizing the connection with the lower assembly 500 of the front frame, thereby saving the material of the second sub-ventilator 2.

[0080] In some embodiments of the present application, the outlet end 22 faces at least part of the heat dissipation assembly 600 of the vehicle 1000.

[0081] In some embodiments of the present application, the second ventilator cavity 20 comprises a first inner wall 23 and a second inner wall 24 connected with the first inner wall 23; wherein from the inlet end 21 to the outlet end 22, the size of the second ventilator cavity 20 along the first direction is smallest at the connection of the first inner wall 23 and the second inner wall 24, and the first inner wall 23 and the second inner wall 24 are smoothly connected. That is, the connection at the tapered and gradually expanding connection is smoothly connected to reduce the hindering effect on the airflow.

[0082] In some embodiments of the present application, the connection of the first inner wall 23 and the second inner wall 24 is smoothly connected by a circular arc surface.

[0083] In some embodiments of the present application, the first sub-shroud 1 has a first mounting position 101 for mounting the air outlet cover 300.

[0084] In some embodiments of the present application, the first sub-shroud 1 further comprises at least one second mounting position 102 for mounting the upper front frame assembly 400.

[0085] In some embodiments of the present application, the upper front frame assembly 400 has at least one opening (not shown in the figure) that communicates the air outlet cavity 31 of the air outlet cover 300 and the air inlet passage of the engine.

[0086] In some embodiments of the present application, a certain number of openings are provided in the contact area between the upper front frame assembly 400 and the air outlet cover 300 to facilitate the flow of air. The hybrid vehicle in the present application only has a lower grille, and when the vehicle is in non-electric mode, the engine is working, and at this time the engine needs a certain amount of air intake, but because the vehicle only has a lower grille and uses a shroud 100 to seal the air intake, it is necessary to introduce part of the gas in the shroud 100 into the air inlet passage of the engine. The rear part of the contact area between the upper front frame assembly 400 and the air outlet cover 300 is opposite the engine air inlet guide pipe (i.e. the air inlet passage), therefore, part of the airflow in the second sub-shroud 2 can enter the air inlet guide pipe (i.e. the air inlet passage) of the engine through the openings on the air outlet cover 300 and the upper front frame assembly 400, meeting the air intake needs of the engine. At the same time, because the engine air intake area has a certain vacuum degree, under the action of the pressure difference, the cooling airflow in the air outlet cavity 31 of the air outlet cover 300 can also flow to the upper part of the heat dissipation assembly 600, playing a flow guiding role.

[0087] In some embodiments of the present application, the air outlet cover 300 and the first sub-shroud 1 are sealed by sealing cotton to prevent air leakage. In other embodiments, other sealing materials can also be used for sealing.

[0088] In some embodiments of the present application, the left and right sides of the air outlet cover 300 (the two sides of the air outlet cover 300 in the second direction X intersecting with the first direction Z) are respectively connected with the upper front frame assembly 400.

[0089] In some embodiments of the present application, the upper front frame assembly 400 is clamped with the first sub-shroud 1.

[0090] In some embodiments of the present application, the number of second mounting positions 102 is multiple, and the first mounting position 101 is located between two adjacent second mounting positions 102.

[0091] In some embodiments of the present application, the first sub-shroud 1 further comprises at least one third mounting position 103 configured to be connected with the front bumper beam 200.

[0092] In some embodiments of the present application, the third mounting position 103 is sealingly connected with the front bumper beam 200 to prevent air leakage.

[0093] In the present embodiment, the third mounting position 103 is sealingly connected with the front bumper beam 200 by sealing cotton strips. In other embodiments, other sealing materials can also be used for sealing.

[0094] In some embodiments of the present application, the second sub-ventilator 2 further comprises a fourth mounting position 201 configured to be connected with the front bumper beam 200.

[0095] In the present embodiment, the fourth mounting position 201 is sealingly connected with the front bumper beam 200 to prevent air leakage.

[0096] In the present embodiment, the third mounting position 103 is sealingly connected with the front bumper beam 200 by sealing cotton strips. In other embodiments, other sealing materials can also be used for sealing.

[0097] In some embodiments of the present application, the first sub-ventilator 1 further comprises a first mounting portion 104 and a second mounting portion 105 configured to be connected with a heat dissipation member support (not shown in the figure) of the vehicle 1000 to fix the heat dissipation assembly 600.

[0098] In some embodiments of the present application, the second sub-ventilator 2 further comprises a third mounting portion 205 and a fourth mounting portion 202 configured to be connected with a heat dissipation member support of the vehicle 1000 to fix the heat dissipation assembly 600.

[0099] In the present embodiment, the first sub-ventilator 1 is connected with the heat dissipation member support through the first mounting portion 104 and the second mounting portion 105, and the second sub-ventilator 2 is connected with the heat dissipation member support through the third mounting portion 205 and the fourth mounting portion 202, so that the first sub-ventilator 1 and the second sub-ventilator 2 can be closely attached to the heat dissipation assembly 600, thereby reducing the risk of air leakage.

[0100] In some embodiments of the present application, the first sub-ventilator 1 and the second sub-ventilator 2 are sealingly connected with the heat dissipation assembly 600, which is conducive to achieving full sealing of the airflow, obtaining a full-sealing ventilator, and preventing the intake air from escaping. At the same time, it can also prevent the hot air at the rear side of the heat dissipation assembly 600 from flowing back into the first ventilating cavity 10 and the second ventilating cavity 20 through the gap between the first sub-ventilator 1 and the second sub-ventilator 2 and the heat dissipation assembly 600, i.e., preventing the hot air from flowing back. The present application fully utilizes the existing structure of the vehicle for sealing design, without the need to add new structures.

[0101] In some embodiments of the present application, the first sub-ducting cover 1 is sealingly connected with the heat dissipation assembly 600 through the second sealing member 4. The second sub-ducting cover 2 is sealingly connected with the heat dissipation assembly 600 through the third sealing member 6.

[0102] In the present embodiment, the second sealing member 4 and the third sealing member 6 are sealing cotton strips. In other embodiments, the second sealing member 4 and the third sealing member 6 can also be other sealing materials.

[0103] In the present embodiment, the heat dissipation assembly 600 includes a first heat dissipation member 61, a second heat dissipation member 62, and a third heat dissipation member 63. The heights of the first heat dissipation member 61, the second heat dissipation member 62, and the third heat dissipation member 63 in the first direction Z increase in sequence. The first heat dissipation member 61 is arranged close to the ducting cover 100. The second heat dissipation member 62 is located between the first heat dissipation member 61 and the third heat dissipation member 63.

[0104] In other embodiments, the heat dissipation assembly 600 can also include a fourth heat dissipation member / fifth heat dissipation member, etc.

[0105] In some embodiments of the present application, the first heat dissipation member 61 is a condenser assembly. The second heat dissipation member 62 is a low-temperature radiator assembly. The third heat dissipation member 63 is a high-temperature radiator assembly. The low temperature and the high temperature are relative.

The front pedestrian protection beam assembly 700 is a comprehensive structural system specially designed for protecting pedestrians in the front part of the vehicle, and is mainly used to reduce the damage to the legs and heads of pedestrians through buffering and energy absorption when the vehicle collides with pedestrians.

[0118] In some embodiments of the present application, the front anti-collision beam 200 has a second guide surface (not shown in the figure) at the position connected with the second sub-choke 2, so as to guide the cooling airflow from the second guide cavity 20 to the first guide cavity 10.

Not only does it meet the air intake requirements of the engine in the non-pure electric mode, but also realizes the functions of upward guiding of the front compartment air inlet, preventing air from escaping and preventing heat backflow. In addition, by dividing the fairing into two parts, the traditional fully enclosed fairing arrangement requires a certain gap with the front crash beam, which saves the arrangement gap and the thickness of the fairing itself, reduces the space occupied by the fairing, realizes the space utilization rate, and makes the front compartment design more flexible.
