[0001] Embodiments of the present application relate to the technical field of vehicles, and in particular to a front engine compartment reinforcing structure and a vehicle. BACKGROUND

[0002] The front engine compartment is used to provide load bearing and installation for the power system, front suspension system, etc. of a vehicle, and is an important component of the vehicle. The front engine compartment is provided with a reinforcing structure. In the process of vehicle collision, the reinforcing structure in the front engine compartment can have the functions of energy absorption and energy transmission, and therefore the rigidity of the front engine compartment plays an important role in the safety performance of the vehicle.

[0003] In addition, with the development of electric vehicles, users have high requirements for the endurance of electric vehicles, and therefore the lightweight design of the vehicle body is also increasingly required. In the related art, in order to improve the overall strength of the front engine compartment, the front engine compartment reinforcing structure includes a plurality of reinforcing beams connected between each other to improve the strength of the front engine compartment.

[0004] However, the plurality of reinforcing beams involve multiple processes such as extrusion, die casting, riveting, rivet pulling, stamping, and welding, which can easily complicate the processing technology. The complication of the processing technology can easily limit the strength of the front engine compartment reinforcing structure and affect the lightweight design of the vehicle body, thereby affecting the safety and experience of the user driving. UTILITY MODEL CONTENT

[0005] In view of this, the present application provides a front engine compartment reinforcing structure and a vehicle. The structure and processing technology of the front engine compartment reinforcing structure of the present application are simple, and can solve the problem of limited structural strength caused by the complicated process of the front engine compartment reinforcing structure, which affects the lightweight design of the vehicle body.

[0006] To achieve the above object, the technical scheme of the embodiments of the present application is as follows:

[0007] In a first aspect, the present application provides a front engine compartment reinforcing structure, which comprises:

[0008] The reinforcing beam comprises:

[0009] The first cross beam has a first end and a second end in the width direction of the vehicle;

[0010] The first side beam has a third end and a fourth end in the length direction of the first side beam, the third end is connected to the first end of the first cross beam, and at least one of the third end and the first end is used to be connected to the left front shock tower;

[0011] The second side beam has a fifth end and a sixth end along the length direction of the second side beam, the fifth end is connected with the second end of the first cross beam, at least one of the fifth end and the second end is used for connecting with the right front shock tower, the sixth end is connected with the fourth end, and at least one of the sixth end and the fourth end is used for connecting with the front wall plate;

[0012] The mounting structure is arranged on the reinforcing beam, and the mounting structure and the reinforcing beam are an integrated structure.

[0013] The front cabin reinforcing structure provided by the embodiment of the application is an integrated structure, which can improve the overall rigidity of the front cabin reinforcing structure and improve the safety performance of the vehicle. In addition, the machining process of the single part of the first cross beam, the first side beam, the second side beam and the mounting structure can be reduced, and the assembly process of the mutual connection of the first cross beam, the first side beam, the second side beam and the mounting structure can also be reduced, thereby saving the machining process and reducing the machining cost.

Since the machining accuracy is improved, the machining strength can be improved, so that the front cabin reinforcing structure has high strength reliability, thereby improving the safety performance of the vehicle.

[0015] It should be noted that the front cabin reinforcing structure provided by the embodiment of the application has high reliability, and the front cabin reinforcing structure can improve the structural strength of the front cabin to meet the strength requirements of the front cabin. Therefore, the strength requirements of the water channel structure in the front cabin are low. The water channel structure in the front cabin can be designed to be relatively simple, which is conducive to reducing the machining process and machining strength standard of the water channel structure in the front cabin, so that the water channel structure can be designed to be lightweight, which is conducive to realizing the lightweight of the whole vehicle.

[0016] The mounting structure can be used to fix at least part of the structure in the front cabin. For example, the mounting structure can be used to fix the front cabin water channel, the brake fluid pot, the heat insulation plate, the air conditioning pipeline and the like, but is not limited to this. Therefore, by integrating the mounting structure and the reinforcing beam into an integrated structure, the integration degree of the front cabin reinforcing structure can be improved, thereby saving the internal space of the front cabin and facilitating the mechanical arrangement in the front cabin.

[0062] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will further describe the specific technical solutions of the present application with reference to the drawings in the embodiments of the present application. The following embodiments are used to explain the present application, but not to limit the scope of the present application.

[0063] In the embodiments of the present application, the terms "first", "second" are only used for descriptive purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0064] In addition, in the embodiments of the present application, the orientation terms such as "upper", "lower", "left" and "right" are defined with respect to the orientation of the components shown in the drawings, and it should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and can be changed accordingly according to the change of the orientation of the components placed in the drawings.

[0065] In the embodiments of the present application, unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, "connection" can be fixed connection, or detachable connection, or integral; can be directly connected, or indirectly connected through intermediate medium.

[0066] In the embodiments of the present application, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes the elements inherent to such process, method, article or device. Without more limitation, the element defined by the sentence "including a" does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0067] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0068] This application provides a front engine compartment reinforcement structure, which is mainly used to improve the structural strength of the front engine compartment of a vehicle, thereby improving the overall vehicle safety performance. The vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Vehicles generally have wheels, a power source, and a transmission system between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate and thus driving the vehicle.

[0069] It should be noted that the type of power source of the vehicle is not limited in the embodiments of this application. For example, for fuel vehicles, the power source can refer to fuel engines such as gasoline engines and diesel engines; for electric vehicles, the power source can refer to electric motors; for hybrid vehicles, the power source can refer to engines or electric motors; for vehicles powered by other means, the power source can refer to devices that generate power.

[0070] The rigidity of a vehicle's front engine compartment plays a crucial role in its safety performance. Furthermore, with the development of electric vehicles, users have higher demands for their range, thus increasing the requirements for lightweight vehicle bodies. The front engine compartment typically incorporates a reinforcing structure to improve its overall strength. In related technologies, this reinforcing structure includes multiple interconnected reinforcing beams to further enhance the front engine compartment's strength.

[0071] However, the multiple reinforcing beams involve various processes such as extrusion, die casting, riveting, bridging, stamping, and welding, which can easily complicate the manufacturing process. This complexity can limit the strength of the front engine compartment reinforcement structure and affect the lightweight design of the vehicle body, thereby impacting the user's driving safety and experience.

[0072] The front engine compartment reinforcing structure provided by the embodiment of the present application is integrally formed with the mounting structure and the reinforcing beam, which can simplify the processing and assembly process, is conducive to reducing the processing cost and improving the processing efficiency. In addition, the mounting structure can be used to fix part of the structure in the front engine compartment, so as to improve the integration of the internal structure of the front engine compartment, reduce the complexity in the assembly process, and simplify the assembly process.

[0073] On this basis, referring to Figures 1 to 4 The embodiment of the present application also provides a front engine compartment reinforcing structure 100. The front engine compartment reinforcing structure 100 can include a reinforcing beam 110 and a mounting structure 120.

[0074] The reinforcing beam 110 includes a first cross beam 111, a first side beam 112, and a second side beam 113. The first cross beam 111 has a first end 111a and a second end 111b along the width direction X of the vehicle.

[0075] The first side beam 112 has a third end 112a and a fourth end 112b along the length direction of the first side beam 112. The third end 112a is connected to the first end 111a of the first cross beam 111, and at least one of the third end 112a and the first end 111a is used to connect the left front shock tower 200.

[0076] The second side beam 113 has a fifth end 113a and a sixth end 113b along the length direction of the second side beam 113. The fifth end 113a is connected to the second end 111b of the first cross beam 111. At least one of the fifth end 113a and the second end 111b is used to connect the right front shock tower 300. The sixth end 113b is connected to the fourth end 112b, and at least one of the sixth end 113b and the fourth end 112b is used to connect the front wall panel 400. The mounting structure 120 is arranged on the reinforcing beam 110, and the mounting structure 120 and the reinforcing beam 110 are integrally formed.

[0077] It should be noted that the front engine compartment reinforcing structure 100 includes the reinforcing beam 110 and the mounting structure 120. The mounting structure 120 and the reinforcing beam 110 being integrally formed can mean that the front engine compartment reinforcing structure 100 is integrally formed.

[0078] In the embodiment of the present application, the front engine compartment reinforcing structure 100 is integrally formed, which can improve the overall rigidity of the front engine compartment reinforcing structure 100 and is conducive to improving the safety performance of the vehicle. In addition, the processing process of the individual parts of the first cross beam 111, the first side beam 112, the second side beam 113, and the mounting structure 120 can be reduced, and the assembly process of the mutual connection of the first cross beam 111, the first side beam 112, the second side beam 113, and the mounting structure 120 can also be reduced, thereby saving the processing process and reducing the processing cost.

[0079] It is easy to understand that the one-piece molded front engine compartment reinforcement structure 100 has a simple structure and manufacturing process. Welding and riveting processes can be eliminated between the first crossbeam 111, the first side beam 112, and the second side beam 113, as well as between the first crossbeam 111, the first side beam 112, the second side beam 113 and the mounting structure 120. In particular, welding and riveting processes can easily lead to deformation and poor dimensional accuracy in the front engine compartment reinforcement structure 100. Therefore, the manufacturing accuracy of the front engine compartment reinforcement structure 100 provided in this embodiment is easy to control, and high manufacturing accuracy can be easily achieved. Since improved manufacturing accuracy can increase manufacturing strength, the front engine compartment reinforcement structure 100 can have high strength and reliability, thereby improving vehicle safety performance.

[0080] It should be noted that, due to the high reliability of the front engine compartment reinforcement structure 100 provided in this application embodiment, the front engine compartment reinforcement structure 100 can improve the structural strength of the front engine compartment to meet the strength requirements of the front engine compartment. Therefore, the strength requirements for the water channel structure inside the front engine compartment are lower. The water channel structure inside the front engine compartment can be designed to be relatively simple, which is beneficial to reducing the processing technology and processing strength standards of the water channel structure inside the front engine compartment, thereby allowing for lightweight design of the water channel structure, which is conducive to achieving overall vehicle lightweighting.

[0081] The mounting structure 120 can be used to secure at least a portion of the structure within the forward engine compartment. For example, the mounting structure 120 can be used, but is not limited to, to secure structures such as the forward engine compartment's water duct, brake fluid reservoir, heat shield, and air conditioning ducts. Therefore, integrating the mounting structure 120 with the reinforcing beam 110 into a single structure improves the integration of the forward engine compartment reinforcing structure 100, thereby saving internal space in the forward engine compartment and facilitating the mechanical layout within it.

[0082] It should be noted that since the first end 111a of the first crossbeam 111 is connected to the third end 112a of the first side beam 112, the connection between at least one of the first end 111a and the third end 112a and the left front shock absorber tower 200 can mean that after the first crossbeam 111 is connected to the first side beam 112, at least one of the first crossbeam 111 and the first side beam 112 is directly connected to the left front shock absorber tower 200. This includes the following: after the first crossbeam 111 is connected to the first side beam 112, it is connected to the left front shock absorber tower 200 via the first crossbeam 111; or, after the first crossbeam 111 is connected to the first side beam 112, it is connected to the left front shock absorber tower 200 via the first side beam 112; or, the connection point between the first crossbeam 111 and the first side beam 112 is connected to the left front shock absorber tower 200. No limitation is made in the embodiments of this application.

[0083] Similarly, since the fifth end 113a of the second side beam 113 is connected with the second end 111b of the first cross beam 111, at least one of the second end 111b and the fifth end 113a for the connection with the right front shock tower 300 can mean that at least one of the first cross beam 111 and the second side beam 113 is directly connected with the right front shock tower 300 after the first cross beam 111 is connected with the second side beam 113. This includes that the first cross beam 111 is connected with the right front shock tower 300 through the first cross beam 111 after the first cross beam 111 is connected with the second side beam 113, or the second side beam 113 is connected with the right front shock tower 300 through the second side beam 113 after the first cross beam 111 is connected with the second side beam 113, or the connection between the first cross beam 111 and the second side beam 113 is connected with the right front shock tower 300. In the embodiments of the present application, none of the above is limited.

[0084] In some embodiments of the present application, referring to Figure 1 The reinforcing beam 110 can form a triangular cast aluminum structure.

[0085] In the embodiments of the present application, the first cross beam 111, the first side beam 112 and the second side beam 113 can form a stable triangular support structure, which is beneficial to improve the strength of the front engine compartment reinforcing structure 100, thereby improving the overall strength of the vehicle and improving the safety performance of the vehicle.

[0086] In addition, by setting the reinforcing beam 110 as a triangular integrated structure, the reinforcing beam 110 and the mounting structure 120 can be a cast aluminum structure. In other words, the whole of the front engine compartment reinforcing structure 100 can be a cast aluminum structure. The front engine compartment reinforcing structure 100 can be made of aluminum material and integrally formed by casting process. It is easy to understand that the weight of aluminum material is lighter, so that the weight of the front engine compartment reinforcing structure 100 can be reduced, which is beneficial to realize the light weight of the front engine compartment, thereby realizing the light weight of the vehicle.

[0087] In addition, since the front engine compartment reinforcing structure 100 is an energy absorption component in the vehicle collision process, by setting the front engine compartment reinforcing structure 100 as a cast aluminum structure, the front engine compartment reinforcing structure 100 can absorb and disperse the collision energy when the vehicle collides, so as to protect the safety of pedestrians and internal members of the vehicle, which is beneficial to the protection of pedestrians.

[0088] In some examples, the cast aluminum structure can be but is not limited to an aluminum alloy.

[0089] In some examples, the included angle between the first side beam 112 and the first cross beam 111 can be an acute angle. The included angle between the second side beam 113 and the first cross beam 111 can be an acute angle. For example, the included angle between the first side beam 112 and the first cross beam 111 can be the same as the included angle between the second side beam 113 and the second cross beam 114.

[0090] In some examples, the thickness of the first cross beam 111 can be between 3mm and 6mm. In this way, the structural strength of the first cross beam 111 can be ensured to ensure the strength of the front engine compartment reinforcing structure 100, and the lightweight of the vehicle can be achieved. In addition, it can also facilitate processing and molding to ensure good casting performance. For example, the thickness of the first cross beam 111 can be 3mm, 4mm, 5mm, 6mm, etc.

[0091] In some examples, the thickness of the first side beam 112 can be between 3mm and 6mm. In this way, the structural strength of the first side beam 112 can be ensured to ensure the strength of the front engine compartment reinforcing structure 100, and the lightweight of the vehicle can be achieved. In addition, it can also facilitate processing and molding to ensure good casting performance. For example, the thickness of the first side beam 112 can be 3mm, 4mm, 5mm, 6mm, etc.

[0092] In some examples, the thickness of the second side beam 113 can be between 3mm and 6mm. In this way, the structural strength of the second side beam 113 can be ensured to ensure the strength of the front engine compartment reinforcing structure 100, and the lightweight of the vehicle can be achieved. In addition, it can also facilitate processing and molding to ensure good casting performance. For example, the thickness of the second side beam 113 can be 3mm, 4mm, 5mm, 6mm, etc.

[0093] In some examples, in the casting process of the front engine compartment reinforcing structure 100, the draft angle can be, but is not limited to, 2.5°.

[0094] Further, with reference to Figures 2 to 4 In some embodiments of the present application, the normal projection of at least part of the mounting structure 120 extends outside the outer contour of the normal projection of the reinforcing beam 110 in the height direction Z of the vehicle. The part of the mounting structure 120 extending outside the outer contour of the reinforcing beam 110 is provided with a reinforcing rib 129.

[0095] In the embodiments of the present application, by extending the mounting structure 120 outside the reinforcing beam 110, it can be used to connect with other structures in the front engine compartment to improve the integration of the front engine compartment reinforcing structure 100. In addition, the mounting structure 120 can improve the overall strength of the front engine compartment reinforcing structure 100.

[0096] In addition, it should be noted that in the embodiments of the present application, the specific extension direction of the mounting structure 120 is not limited. The extension direction of the mounting structure 120 can be set according to the vehicle model of different vehicles and the shape and position of the structure arranged in the front engine compartment.

[0097] In some examples, a plurality of reinforcing ribs 129 can be arranged on the reinforcing beam 110. The plurality of reinforcing ribs 129 can be arranged on at least one side surface of the first cross beam 111, the first side beam 112 and the second side beam 113 to improve the structural strength of the reinforcing beam 110. The plurality of reinforcing ribs 129 can extend in different directions. For example, the plurality of reinforcing ribs 129 can be arranged in a staggered manner to more effectively improve the structural strength of the reinforcing beam 110.

[0098] In some examples, the reinforcing beam 110 is provided with a ejector pin. The ejector pin can be used to eject the formed front cabin reinforcing structure 100 from the mold after the mold is opened, so as to facilitate subsequent processing and collection.

[0099] For example, the ejector pin can be arranged at a position where the plurality of reinforcing ribs 129 are staggered, so as to reduce the redundant structure on the reinforcing beam 110 by not additionally arranging the ejector pin at other positions of the reinforcing beam 110 while meeting the casting process.

[0100] In the embodiments of the present application, the specific shape of the ejector pin is not limited.

[0101] It should be noted that, in the embodiments of the present application, the thickness of the reinforcing rib 129 can be between 2.5 mm and 6 mm. For example, the thickness of the reinforcing rib 129 can be 2.5 mm, 3.5 mm, 4 mm, 5 mm, 6 mm, etc.

[0102] On this basis, with reference to Figure 2 and Figure 3 In some embodiments of the present application, the mounting structure 120 includes a first mounting member 121. The first mounting member 121 is arranged at the first end 111a and / or the third end 112a. The first mounting member 121 is detachably connected with the left front shock tower 200.

[0103] The mounting structure 120 includes a second mounting member 122. The second mounting member 122 is arranged at the second end 111b and / or the fifth end 113a. The second mounting member 122 is detachably connected with the right front shock tower 300.

[0104] The mounting structure 120 includes a third mounting member 123. The third mounting member 123 is arranged at the fourth end 112b and / or the sixth end 113b. The third mounting member 123 is detachably connected with the front wall panel 400.

[0105] In the embodiments of the present application, the first mounting member 121 can be used to connect the stiffening beam 110 and the left front shock tower 200. The second mounting member 122 can be used to connect the stiffening beam 110 and the right front shock tower 300. The third mounting member 123 can be used to connect the stiffening beam 110 and the front wall panel 400. Therefore, the fixing of the front engine bay stiffening structure 100 can be achieved through the first mounting member 121, the second mounting member 122 and the third mounting member 123.

[0106] Since the mounting structure 120 is an integral structure with the stiffening beam 110, the first mounting member 121, the second mounting member 122 and the third mounting member 123 are integral structures with the stiffening beam 110. Therefore, during the installation of the front engine bay stiffening structure 100, the connection processes of the first mounting member 121 and the stiffening beam 110, the second mounting member 122 and the stiffening beam 110, and the third mounting member 123 and the stiffening beam 110 can be omitted.

[0107] It should be noted that in the embodiments of the present application, the number of mounting points between the first mounting member 121 and the left front shock tower 200, the number of mounting points between the second mounting member 122 and the right front shock tower 300, and the number of mounting points between the third mounting member 123 and the front wall panel 400 are not limited, as long as the connection reliability of the front engine bay stiffening structure 100 can be ensured.

[0108] Exemplarily, two mounting points can be respectively arranged on the first mounting member 121, the second mounting member 122 and the third mounting member 123, for respectively detachably connecting with the left front shock tower 200, the right front shock tower 300 and the front wall panel 400.

[0109] In some examples, the first mounting member 121, the second mounting member 122 and the third mounting member 123 can be threadedly connected with the left front shock tower 200, the right front shock tower 300 and the front wall panel 400 through a locking member. For example, at least M8 threaded connection.

[0110] In some examples, along the length direction Y of the vehicle, a single tolerance of 2mm can be arranged between the front wall panel 400 and the third mounting member 123, so as to improve the assembly efficiency of the front engine bay stiffening structure 100 and the left front shock tower 200 and the right front shock tower 300.

[0111] Further, with reference to Figure 2 and Figure 3 In some embodiments of the present application, the mounting structure 120 comprises a first mounting assembly 124. The first mounting assembly 124 is arranged on the first cross beam 111.

[0112] The first mounting assembly 124 comprises a first connecting piece 1241. The first connecting piece 1241 extends forward along the length direction Y of the vehicle on the first cross beam 111, and the first connecting piece 1241 is provided with a first connecting hole 1241a for connecting with the front engine compartment gutter.

[0113] In some examples, the first mounting assembly 124 can comprise a second connecting piece 1242. The second connecting piece 1242 extends along the height direction Z of the vehicle on the first cross beam 111, and the second connecting piece 1242 is provided with a second connecting hole 1242a for connecting with the front engine compartment gutter.

[0114] The front engine compartment gutter can be used to collect and discharge liquid such as rainwater, so as to avoid the liquid from flowing into the key area of the vehicle body and affecting the service life and normal operation of the vehicle.

[0115] In the embodiment of the application, the first mounting assembly 124 can be used to fix the front engine compartment gutter, so as to integrate the front engine compartment gutter on the front engine compartment reinforcement structure 100, which is beneficial to improve the integration of the front engine compartment.

[0116] In some examples, the first connecting piece 1241 can be flush with the upper surface of the first cross beam 111, or Figure 3 part of the first connecting piece 1241 can protrude from the upper surface of the first cross beam 111 to support the front engine compartment gutter. For example, the first connecting piece 1241 can be a bent structure.

[0117] In some examples, the number of first connecting pieces 1241 can be multiple. The multiple first connecting pieces 1241 are arranged at intervals on the first cross beam 111 to fix different positions of the front engine compartment gutter, which is beneficial to improve the connection stability of the front engine compartment gutter.

[0118] In some examples, the first connecting hole 1241a on the first connecting piece 1241 can be but is not limited to a threaded hole for locking connection with the front engine compartment gutter.

[0119] In some examples, referring to Figure 4 Since the first connecting piece 1241 protrudes outside the reinforcement beam 110, the first connecting piece 1241 forms a cantilever structure relative to the reinforcement beam 110, therefore, in order to improve the reliability of the first connecting piece 1241, the first connecting piece 1241 can be provided with a reinforcing boss 128. The first connecting hole 1241a can be arranged on the reinforcing boss 128. For example, the threaded hole is at least M6.

[0120] For example, the outer diameter of the reinforcing boss 128 on the first connecting piece 1241 is at least 14 mm. The thickness of the reinforcing boss 128 is at least 12 mm.

[0121] In some examples, the first connecting member 1241 can further be provided with a reinforcing rib 129 for improving the structural strength of the first connecting member 1241 and the second connecting member 1242 with the reinforcing beam 110. The reinforcing rib 129 can extend from the first cross beam 111 to the first connecting hole 1241a.

[0122] The thickness of the reinforcing rib 129 can be set according to the size of the first connecting member 1241 extending from the reinforcing beam 110 and the distance between the first connecting hole 1241a and the reinforcing beam 110, which is not specifically limited in the embodiment of the present application.

[0123] In some examples, the second connecting member 1242 extends along the height direction Z of the vehicle, and thus the second connecting member 1242 can protrude from the upper surface of the first cross beam 111. The second connecting member 1242 can support the front engine compartment gutter.

[0124] The number of the second connecting member 1242 can be but not limited to one. Along the length direction (width direction X of the vehicle) of the first cross beam 111, the second connecting member 1242 can be close to the end of the first cross beam 111. The first connecting member 1241 can be close to the middle region of the first cross beam 111. The first connecting member 1241 and the second connecting member 1242 can support different regions of the front engine compartment gutter to improve the connection stability of the front engine compartment gutter.

[0125] It should be noted that the position of the first connecting member 1241 and the second connecting member 1242 on the first cross beam 111 is not limited in the embodiment of the present application, which can be set according to the structure of the front engine compartment gutter.

[0126] In some examples, referring to Figure 4 , the second connecting member 1242 protrudes from the upper surface of the first cross beam 111, for example, the second connecting member 1242 can be a boss structure. The second connecting hole 1242a is provided on the boss structure. The outer periphery of the second connecting member 1242 can also be provided with a reinforcing rib 129 to ensure the structural rigidity and strength of the second connecting member 1242.

[0127] For example, the outer diameter of the boss structure can be greater than or equal to 14 mm.

[0128] Further, referring to Figure 2 and Figure 3 In some embodiments of the present application, the mounting structure 120 further comprises a second mounting assembly 125. The second mounting assembly 125 comprises a first fixing member 1251 and a second fixing member 1252.

[0129] The first fixing member 1251 is arranged on the first cross beam 111 and extends along the rear side of the vehicle length direction Y. The first fixing member 1251 is provided with a first fixing hole 1251a for connecting with the brake fluid pot. The second fixing member 1252 is arranged on one of the first side beam 112 and the second side beam 113. The second fixing member 1252 extends towards the first cross beam 111. The second fixing member 1252 is provided with a second fixing hole 1252a for connecting with the brake fluid pot.

[0130] The brake fluid pot can be used to store brake fluid. The brake fluid plays an important role in ensuring the braking performance of the vehicle and the safety of driving.

[0131] In the embodiment of the present application, the second mounting assembly 125 can be used to fix the brake fluid pot. The second mounting assembly 125 can integrate the brake fluid pot on the front engine compartment reinforcement structure 100 to improve the integration of the front engine compartment. The brake fluid pot stores brake fluid and has a certain weight. By arranging the first fixing member 1251 and the second fixing member 1252 at different positions on the reinforcement beam 110, the weight of the brake fluid pot can be shared to improve the reliability of the brake fluid pot.

[0132] For example, the first fixing member 1251 is arranged on the first cross beam 111. The second fixing member 1252 can be arranged on the first side beam 112 or the second side beam 113.

[0133] In some examples, the brake fluid pot can be detachably connected with the first fixing member 1251 and the second fixing member 1252. The first fixing hole 1251a on the first fixing member 1251 and the second fixing hole 1252a on the second fixing member 1252 can be used for detachable connection with the brake fluid pot.

[0134] In some examples, the positions of the first fixing member 1251 and the second fixing member 1252 can be arranged according to the position and size of the brake fluid pot. For example, the first fixing member 1251 and the second fixing member 1252 can be arranged inside the triangular structure formed by the reinforcement beam 110. The first fixing member 1251 and the second fixing member 1252 are close to each other.

[0135] In some examples, referring to Figure 4 , the first fixing member 1251 and the second fixing member 1252 extend outside the reinforcement beam 110 to form a cantilever structure. The first fixing member 1251 and the second fixing member 1252 can be provided with a reinforcing rib 129 to improve the structural strength of the first fixing member 1251 and the second fixing member 1252 with the reinforcement beam 110.

[0136] Exemplarily, the reinforcing ribs 129 on the first fixing member 1251 can extend from the direction of the reinforcing beam 110 to the direction of the first fixing hole 1251a. The reinforcing ribs 129 on the second fixing member 1252 can extend from the direction of the reinforcing beam 110 to the direction of the second fixing hole 1252a.

[0137] In the first fixing member 1251, a reinforcing boss 128 can be arranged at a position corresponding to the first fixing hole 1251a. In the second fixing member 1252, a reinforcing boss 128 can also be arranged at a position corresponding to the second fixing hole 1252a, so as to improve the support stability of the brake fluid pot.

[0138] Further, referring to Figure 2 and Figure 3 In some embodiments of the present application, the mounting structure 120 further comprises a first adapter 126. The first adapter 126 is arranged on the second side beam 113 and extends along the height direction Z of the vehicle, and the first adapter 126 is provided with a first adapter hole 126a for connecting with the heat insulation plate. The axial direction of the first adapter hole 126a intersects the height direction Z of the vehicle.

[0139] The heat insulation plate can be used to block the influence of high temperature from the outside on the engine or motor, so as to reduce the possibility of overheating of the engine or motor, thereby affecting the working efficiency and service life.

[0140] In the embodiments of the present application, the first adapter 126 can be used to fix the heat insulation plate, so as to integrate the heat insulation plate on the front engine compartment reinforcing structure 100, which is beneficial to improve the integration of the front engine compartment.

[0141] Based on the structure and fixing direction of the heat insulation plate, the first adapter 126 can extend downward of the second side beam 113. Exemplarily, the axial direction of the first adapter hole 126a on the first adapter 126 can be the same as the length direction Y of the vehicle, or can be deflected relative to the length direction Y of the vehicle.

[0142] In some examples, when the first adapter 126 is located below the second side beam 113, a recess can be arranged on the upper surface of the second side beam 113 at a position corresponding to the first adapter 126. The recess can be used to improve the quality of the casting process and ensure the yield of the front engine compartment reinforcing structure 100.

[0143] Further, referring to Figure 2 and Figure 3 In some embodiments of the present application, the mounting structure 120 further comprises a second adapter 127.

The axial direction of the second adapter hole 127a intersects the height direction Z of the vehicle.

[0144] The air conditioning pipeline can be used to effectively connect air conditioning components (such as a compressor, a condenser, an evaporator, an expansion valve, etc.) installed at various positions of the automobile, to form a complete and efficient air conditioning system.

[0145] In the embodiments of the present application, the second adapter 127 can be used to fix the air conditioning pipeline, so as to integrate the air conditioning pipeline on the front engine compartment reinforcing structure 100, thereby facilitating improvement of the integration degree of the front engine compartment.

[0146] In some examples, when the second adapter 127 is located above the first cross beam 111, a recess can be arranged on the lower surface of the first cross beam 111 at a position corresponding to the second adapter 127. The recess can be used to improve the quality of the casting process and ensure the yield of the front engine compartment reinforcing structure 100.

[0147] Further, with reference to Figure 2 In some embodiments of the present application, the reinforcing beam 110 can further include a second cross beam 114. The second cross beam 114 is arranged spaced apart from the first cross beam 111 along the length direction Y of the vehicle, and the second cross beam 114 is located at the rear side of the first cross beam 111. The fourth end 112b of the first side beam 112 and the sixth end 113b of the second side beam 113 are respectively connected to the two ends of the second cross beam 114 in the length direction.

[0148] In the embodiments of the present application, the end portions of the first side beam 112 and the second side beam 113 used for connecting the front wall panel 400 can be connected through the second cross beam 114. In other words, the first cross beam 111, the first side beam 112, the second side beam 113 and the second cross beam 114 can form a quadrilateral structure, so as to improve the overall strength of the reinforcing beam 110.

[0149] In some examples, the length of the second cross beam 114 can be less than the length of the first cross beam 111. The first cross beam 111, the first side beam 112, the second side beam 113 and the second cross beam 114 can form a trapezoidal structure.

[0150] In some examples, the third mounting member 123 can be arranged on the second cross beam 114.

[0151] The embodiments of the present application also provide a vehicle. With reference to Figure 1 The vehicle can include a left front shock tower 200, a right front shock tower 300, a front wall panel 400 and a front engine compartment reinforcing structure 100.

[0152] The left front shock tower 200 and the right front shock tower 300 are arranged at intervals in the width direction X of the vehicle.
