[0050] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0051] With the development of the vehicle industry, in order to improve product competitiveness, vehicles usually use center-mounted air conditioners instead of offset air conditioners in traditional models. The air conditioning vents of center-mounted air conditioners and offset air conditioners both include air inlets and air outlets. The air inlet of the offset air conditioner is usually set on the front enclosure body, and the air outlet is usually set on the vehicle water flow channel. The air inlet and air outlet of the center-mounted air conditioner are both set on the front enclosure body. Therefore, compared with the offset air conditioner, an air outlet is usually required on the front enclosure body of the vehicle equipped with the center-mounted air conditioner, resulting in a decrease in the rigidity of the front enclosure body.

[0052] Reference below Figure 1-Figure 7 A cowl assembly 100 of a vehicle according to an embodiment of the present invention is described.

[0053] like Figure 1 and Figure 2 As shown, the front enclosure assembly 100 of the vehicle according to the embodiment of the utility model includes: a front enclosure body 1, which is formed with an air-conditioning vent 11; a reinforcement structure 2, which is located at the front side of the front enclosure body 1, and is fixedly connected to the front enclosure body 1 and is arranged around the air-conditioning vent 11, and a first cavity 3 is formed between the reinforcement structure 2 and the front enclosure body 1, and the first cavity 3 is arranged around the air-conditioning vent 11.

[0054] The front enclosure body 1 is arranged between the passenger compartment and the engine compartment, which can isolate the noise and vibration of the engine compartment and improve the comfort of the passengers. The front enclosure body 1 is formed with an air conditioning vent 11, which includes an air inlet 111 and an air outlet 112. The air inlet 111 and the air outlet 112 are arranged along the width direction of the vehicle, that is, Figure 1 The air conditioning vents 11 can be connected to the air exchange channel between the vehicle and the outside, so that the inside of the vehicle and the outside air can be exchanged, which is conducive to delivering the cold air or warm air treated by the air conditioner into the vehicle, thereby adjusting the temperature inside the vehicle, and the air conditioning vents 11 can also discharge the air inside the vehicle to the outside of the vehicle to balance the air pressure inside and outside the vehicle, so as to make the air inside the vehicle circulate and improve the riding comfort of the passengers.

[0055] The front enclosure body 1 can support and install key components such as a clutch pedal, a brake pedal or an instrument panel. In order to improve the structural strength of the front enclosure body 1, a reinforcement structure 2 can be provided. Along the length direction of the vehicle, the reinforcement structure 2 can be located at the front side of the front enclosure body 1, that is, along the length direction of the vehicle, the reinforcement structure 2 is located on the side of the front enclosure body 1 away from the rear end of the vehicle. Providing the reinforcement structure 2 at the front side of the front enclosure body 1 can improve the structural strength of the front enclosure body 1, and can also improve the installation rigidity of key components such as a clutch pedal, a brake pedal or an instrument panel, thereby improving the safety performance of the vehicle.

[0056] The reinforcing structure 2 can be connected to the front enclosure body 1 by welding, or by bolts. However, the present application is not limited thereto, and the reinforcing structure 2 can also be connected to the front enclosure body 1 by other means, as long as the reinforcing structure 2 is fixedly connected to the front enclosure body 1. The present application takes the reinforcing structure 2 being connected to the front enclosure body 1 by welding and being arranged around the air conditioning vent 11 as an example for explanation, and the welding connection can improve the connection reliability of the reinforcing structure 2 and the front enclosure body 1, and reduce the risk of the reinforcing structure 2 falling off the front enclosure body 1, thereby improving the structural stability of the front enclosure assembly 100. The reinforcing structure 2 being arranged around the air conditioning vent 11 can make the arrangement of the reinforcing structure 2 reasonable, which is conducive to the reinforcing structure 2 strengthening the strength of the front enclosure body 1 along the circumference of the air conditioning vent 11, and reducing the risk of the front enclosure body 1 cracking due to the reduction of the structural strength near the air conditioning vent 11 on the front enclosure body 1.

[0057] As an embodiment of the present application, the reinforcing structure 2 can be set to an arc shape so that a first cavity 3 is formed between the reinforcing structure 2 and the front enclosure body 1. As an embodiment of the present application, the reinforcing structure 2 can be set to a "J" shape so that a first cavity 3 is formed between the reinforcing structure 2 and the front enclosure body 1. By forming the first cavity 3 between the reinforcing structure 2 and the front enclosure body 1 and the first cavity 3 is arranged around the air conditioning vent 11, when the vehicle collides, the first cavity 3 can collapse and absorb energy along the circumference of the air conditioning vent 11, reduce the collision force directly transmitted to the passenger compartment to cause the passenger compartment to collapse and deform, improve the collision performance of the vehicle, and thus help improve the safety of the vehicle, and the first cavity 3 can block the transmission path of engine compartment noise and vibration, reduce the risk of engine compartment noise and vibration being transmitted to the passenger compartment, improve the NVH (Noise, Vibration, Harshness) performance of the vehicle, and thus improve the comfort of the occupants.

[0058] Furthermore, the reinforcement structure 2 can be provided as at least one, and providing the reinforcement structure 2 as at least one can improve the reinforcement reliability of the reinforcement structure 2. When the reinforcement structure 2 is provided as a plurality, when one of the reinforcement structures 2 fails, the other reinforcement structures 2 can continue to play a reinforcing role, reducing the risk of reinforcement failure of the front enclosure body 1, thereby further improving the safety performance of the vehicle.

[0059] Specifically, along the length direction of the vehicle, the reinforcement structure 2 is arranged on the front side of the front enclosure body 1, which is conducive to improving the structural strength of the front enclosure body 1, thereby improving the safety performance of the vehicle. The reinforcement structure 2 is welded to the front enclosure body 1, which improves the connection reliability of the reinforcement structure 2 and the front enclosure body 1 and reduces the risk of reinforcement failure of the front enclosure body 1. A first cavity 3 is formed between the reinforcement structure 2 and the front enclosure body 1, which blocks the transmission path of engine compartment noise and vibration, reduces the risk of engine compartment noise and vibration being transmitted to the passenger compartment, improves the NVH performance of the vehicle, and further improves the comfort of the passengers. When the vehicle collides, the first cavity 3 can collapse and absorb energy, reduce the collision force directly transmitted to the passenger compartment to cause the passenger compartment to collapse and deform, improve the collision performance of the vehicle, and further help improve the safety of the vehicle.

[0060] Thus, by providing the reinforcement structure 2, the structural strength of the front enclosure body 1 can be improved, thereby improving the safety performance of the vehicle, and the first cavity 3 is formed between the reinforcement structure 2 and the front enclosure body 1, which is beneficial to improving the NVH performance of the vehicle. When the vehicle collides, the first cavity 3 can also collapse and absorb energy, reducing the collision force directly transmitted to the passenger compartment to cause the passenger compartment to collapse and deform, thereby improving the collision performance of the vehicle, and further helping to improve the safety of the vehicle.

[0061] As some embodiments of the present application, the first cavity 3 is arc-shaped, and such a configuration can make the front wall assembly 100 have better structural strength, and the arc-shaped first cavity 3 can better disperse the collision force, reduce the risk of deformation of the reinforcement structure 2 when it is subjected to a small stress, thereby reducing the risk of deformation of the reinforcement structure 2 when the vehicle is driving normally or bumping. Designing the first cavity 3 to be arc-shaped can also reduce unnecessary material use while improving the strength and rigidity of the first cavity 3, which is conducive to the lightweight design of the vehicle.

[0062] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the reinforcement structure 2 and the front enclosure body 1 jointly define a first cavity 3 .

[0063] In some embodiments of the present application, the reinforcement structure 2 and the front enclosure body 1 are connected by bolts to define a first cavity 3. In some embodiments of the present application, the reinforcement structure 2 and the front enclosure body 1 are connected by welding to define a first cavity 3. When the vehicle collides, the reinforcement structure 2 is subjected to a large collision force and collapses into the first cavity 3 to absorb energy, which can reduce the collision force directly transmitted to the passenger compartment, causing the passenger compartment to collapse and deform, which is beneficial to improving the collision performance of the vehicle, thereby further improving the safety of the vehicle.

[0064] In some embodiments of the present invention, Figure 1 , Figure 4-Figure 6 As shown, the reinforcement structure 2 may include: a first front wall reinforcement 21, a second front wall reinforcement 22 and a front wall cross beam 23, the first front wall reinforcement 21 and the second front wall reinforcement 22 are opposite and spaced apart along the width direction of the vehicle, the front wall cross beam 23 extends along the width direction of the vehicle, and the front wall cross beam 23 is connected to both the first front wall reinforcement 21 and the second front wall reinforcement 22.

[0065] The first front wall reinforcement 21 and the second front wall reinforcement 22 are arranged opposite to each other along the width direction of the vehicle. Figure 1 The first and second front wall reinforcements 21 and 22 are arranged at intervals, so that the first and second front wall reinforcements 21, 22 and the front wall cross beam 23 can be arranged around the front wall body 1, so that the reinforcement structure 2 can evenly improve the structural strength of the front wall body 1 around the front wall body 1, and reduce the risk of cracking or even disconnection of the front wall body 1 due to low local strength of the front wall body 1.

[0066] The dash cross member 23 extends along the width direction of the vehicle, which is beneficial for the dash cross member 23 to uniformly increase the rigidity of the dash body 1 along the width direction of the vehicle. When the vehicle collides, the dash cross member 23 can effectively absorb the collision force along the width direction of the vehicle, protect the safety of the passenger compartment, and reduce the risk of occupant injury.

[0067] The front wall cross beam 23 and the first front wall reinforcement 21 and the second front wall reinforcement 22 can be welded and connected, or the front wall cross beam 23 and the first front wall reinforcement 21 and the second front wall reinforcement 22 can be connected by bolts. However, the present application is not limited thereto, and the front wall cross beam 23 and the first front wall reinforcement 21 and the second front wall reinforcement 22 can also be connected by other means, as long as the front wall cross beam 23 and the first front wall reinforcement 21 and the second front wall reinforcement 22 are all connected. The present application is explained by taking the welding connection of the front wall cross beam 23 and the first front wall reinforcement 21 and the second front wall reinforcement 22 as an example, and the welding connection can improve the connection reliability of the front wall cross beam 23 and the first front wall reinforcement 21 and the second front wall reinforcement 22, reduce the risk of cracking of the front wall cross beam 23 and the first front wall reinforcement 21 and the second front wall reinforcement 22, thereby improving the structural stability of the front wall assembly 100. The front wall cross beam 23 is connected to the first front wall reinforcement 21 and the second front wall reinforcement 22, and can also transmit collision force to each other among the front wall cross beam 23, the first front wall reinforcement 21 and the second front wall reinforcement 22, thereby optimizing the force transmission path of the vehicle and reducing the risk of deformation of the reinforcement structure 2 when subjected to impact force.

[0068] In some embodiments of the present invention, Figure 1 As shown, a first cavity 3 is formed between at least one of the first dash reinforcement 21 and the dash body 1 , between the second dash reinforcement 22 and the dash body 1 , and between the dash cross beam 23 and the dash body 1 .

[0069] Among them, as an embodiment of the present application, a first cavity 3 is formed between the first front wall reinforcement 21 and the front wall body 1, between the second front wall reinforcement 22 and the front wall body 1, or between the front wall cross beam 23 and the front wall body 1. As an embodiment of the present application, a first cavity 3 is formed between the first front wall reinforcement 21 and the front wall body 1, between the second front wall reinforcement 22 and the front wall body 1, or between the front wall cross beam 23 and the front wall body 1. As an embodiment of the present application, a first cavity 3 is formed between the first front wall reinforcement 21 and the front wall body 1, between the second front wall reinforcement 22 and the front wall body 1, or between the front wall cross beam 23 and the front wall body 1. Such a setting can make the front wall assembly 100 have a variety of ways to define the first cavity 3, and the first cavity 3 can be formed at different positions according to the use requirements, so that the setting position of the first cavity 3 is more reasonable.

[0070] This application takes the example that the first cavity 3 is formed between the first front wall reinforcement 21 and the front wall body 1, between the second front wall reinforcement 22 and the front wall body 1, or between the front wall cross beam 23 and the front wall body 1 as an example for explanation. Such a configuration can increase the number of first cavities 3, which is conducive to better dispersing the collision force. When the vehicle collides, different positions of the front wall assembly 100 can collapse and absorb energy, further reducing the collision force directly transmitted to the passenger compartment to cause the passenger compartment to collapse and deform, improving the collision performance of the vehicle, and further improving the safety of the vehicle.

[0071] In some embodiments of the present invention, Figure 1 , Figure 4-Figure 6 As shown, a first sub-cavity 31 is formed between the first front enclosure reinforcement 21 and the front enclosure body 1, a second sub-cavity 32 is formed between the second front enclosure reinforcement 22 and the front enclosure body 1, and a third sub-cavity 33 is formed between the front enclosure cross beam 23 and the front enclosure body 1. The third sub-cavity 33 connects the first sub-cavity 31 and the second sub-cavity 32. The first sub-cavity 31, the second sub-cavity 32 and the third sub-cavity 33 are all constructed as parts of the first cavity 3.

[0072] Among them, by providing the first sub-cavity 31, the second sub-cavity 32 and the third sub-cavity 33, the number of cavities can be increased, and multiple cavities are conducive to better dispersing the collision force. When the vehicle collides, the first sub-cavity 31, the second sub-cavity 32 and the third sub-cavity 33 can all collapse and absorb energy, reducing the collision force directly transmitted to the passenger compartment to cause the passenger compartment to collapse and deform, thereby improving the collision performance of the vehicle, and further improving the safety of the vehicle.

[0073] The third sub-cavity 33 is connected to the first sub-cavity 31 and the second sub-cavity 32, that is, the first sub-cavity 31, the second sub-cavity 32 and the third sub-cavity 33 are connected. When the vehicle collides, the first front wall reinforcement 21, the second front wall reinforcement 22 and the front wall cross beam 23 can be used as a whole to collapse and absorb energy, thereby effectively reducing the collision force transmitted to the passenger compartment, reducing the risk of collapse and deformation of the passenger compartment, and being more conducive to protecting the passengers in the passenger compartment and improving the safety of the vehicle.

[0074] In some embodiments of the present invention, Figure 1 and Figure 7 As shown, the reinforcement structure 2 may also include: a first connecting member 24, the first connecting member 24 is connected between the first front enclosure reinforcement 21 and the front enclosure cross beam 23, a fourth sub-cavity 34 is formed between the first connecting member 24 and the front enclosure body 1, the fourth sub-cavity 34 connects the first sub-cavity 31 and the third sub-cavity 33, and the fourth sub-cavity 34 is constructed as a part of the first cavity 3.

[0075] The first connecting member 24 is connected to the first front wall reinforcement 21, and the first connecting member 24 is connected to the front wall cross beam 23, that is, the first front wall reinforcement 21 is connected to the front wall cross beam 23 through the first connecting member 24. For example, the first connecting member 24, the first front wall reinforcement 21, and the front wall cross beam 23 can be welded, or the first connecting member 24, the first front wall reinforcement 21, and the front wall cross beam 23 can be connected by bolts. However, the present application is not limited thereto, and the first connecting member 24, the first front wall reinforcement 21, and the front wall cross beam 23 can also be connected by other methods, as long as the first connecting member 24, the first front wall reinforcement 21, and the front wall cross beam 23 are fixedly connected. The present application takes the welding connection between the first connecting member 24 and the first front wall reinforcement 21 and the front wall cross beam 23 as an example for explanation. The welding connection can improve the connection reliability between the first connecting member 24 and the first front wall reinforcement 21, and the first connecting member 24 and the front wall cross beam 23, and reduce the risk of separation between the first connecting member 24 and the first front wall reinforcement 21, and the first connecting member 24 and the front wall cross beam 23, thereby helping to improve the structural stability of the reinforced structure 2.

[0076] In addition, a fourth sub-cavity 34 is formed between the first connecting member 24 and the front enclosure body 1, a first sub-cavity 31 is formed between the first front enclosure reinforcement 21 and the front enclosure body 1, a second sub-cavity 32 is formed between the second front enclosure reinforcement 22 and the front enclosure body 1, and a third sub-cavity 33 is formed between the front enclosure cross beam 23 and the front enclosure body 1. Such an arrangement can form four cavities between the reinforcement structure 2 and the front enclosure body 1, thereby facilitating better dispersion of collision forces.

[0077] The fourth sub-cavity 34 is connected to the first sub-cavity 31 and the third sub-cavity 33, and the third sub-cavity 33 is connected to the first sub-cavity 31 and the second sub-cavity 32, that is, the first sub-cavity 31, the second sub-cavity 32, the third sub-cavity 33 and the fourth sub-cavity 34 are connected. When the vehicle collides, the first front wall reinforcement 21, the second front wall reinforcement 22, the front wall cross beam 23 and the first connecting member 24 can be used as a whole to collapse and absorb energy, thereby effectively reducing the collision force transmitted to the passenger compartment, which is conducive to improving the safety of the vehicle.

[0078] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the front enclosure assembly 100 may further include: a connecting crossbeam 4, the connecting crossbeam 4 is fixedly connected to the front enclosure body 1, and the connecting crossbeam 4 is connected to the reinforcing structure 2 to form an annular force transmission structure.

[0079] The connecting crossbeam 4 and the front enclosure body 1 can be connected by welding, or the connecting crossbeam 4 and the front enclosure body 1 can be connected by bolts. In addition, the connecting crossbeam 4 and the reinforcing structure 2 are connected, and the connecting crossbeam 4 and the reinforcing structure 2 can be connected by welding, or the connecting crossbeam 4 and the reinforcing structure 2 can be connected by bolts.

[0080] As some embodiments of the present application, the connecting beam 4 can be arranged along the width direction of the vehicle (ie Figure 1 The connecting crossbeam 4 is extended in the Y direction of the vehicle body 1, and the connecting crossbeam 4 can be connected to the first front wall reinforcement 21 and the second front wall reinforcement 22. This arrangement can form a ring-shaped force transmission structure with the connecting crossbeam 4 and the reinforcement structure 2, thereby more effectively improving the structural strength of the front wall body 1, thereby further improving the safety performance of the vehicle.

[0081] As some embodiments of the present application, the reinforcement structure 2 can be configured in a "U" shape, and the connecting crossbeam 4 can be connected to the first front wall reinforcement 21 and the second front wall reinforcement 22 to form an annular force transmission structure with the reinforcement structure 2. Such a configuration can make the structural form of the reinforcement structure 2 reasonable and can effectively improve the structural strength of the front wall body 1.

[0082] Furthermore, the connecting beam 4 can have a connecting beam body 42 and a cover plate 43, the connecting beam body 42 can be constructed as a "U"-shaped structure, and the connecting beam body 42 and the cover plate 43 can be welded to form a second cavity 41 between the connecting beam body 42 and the cover plate 43.

[0083] In some embodiments of the present invention, Figure 3 As shown, the connecting beam 4 is formed with a second cavity 41 .

[0084] Among them, by forming a second cavity 41 on the connecting beam 4, when the vehicle collides, the connecting beam 4 can collapse and absorb energy, further reducing the collision force directly transmitted to the passenger compartment to cause the passenger compartment to collapse and deform, further improving the collision performance of the vehicle, and further being conducive to improving the safety of the vehicle.

[0085] As some embodiments of the present application, the cross section of the second cavity 41 can be configured as a polygon, for example, the cross section of the second cavity 41 can be configured as a triangle, a quadrilateral, etc. It can be understood that the polygonal structure has stability, and such a configuration can improve the structural strength of the connecting beam 4, so that the connecting beam 4 can effectively withstand the collision force, thereby improving the frontal collision performance of the vehicle.

[0086] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the connecting cross member 4 is designed as a lower cross member of a windshield of the vehicle.

[0087] The vehicle may have two A-pillars, and the two A-pillars may be arranged opposite to each other along the width direction of the vehicle, that is, Figure 1 The two ends of the windshield lower cross beam 4 can be connected to the A-pillars of the vehicle respectively. By configuring the connecting cross beam 4 as the windshield lower cross beam of the vehicle, the number of parts of the front wall assembly 100 can be reduced, thereby reducing the difficulty of assembling the front wall assembly 100, which is conducive to improving production efficiency. In addition, by configuring the connecting cross beam 4 as the windshield lower cross beam of the vehicle, it is conducive to realizing the lightweight design of the vehicle.
