Description

Technical Field

[0001] This application relates to the field of vehicle body structure technology, and in particular to a ventilation cover mounting bracket and vehicle. Background Technology

[0002] Torsional stiffness of a vehicle is one of the important performance indicators for evaluating the strength and rigidity of the vehicle body structure. It mainly reflects the vehicle's ability to resist torsional deformation during driving, especially on uneven roads or when subjected to lateral forces. This indicator has a significant impact on the vehicle's handling stability, safety, comfort, and durability.

[0003] In the front structure of a vehicle body, the engine compartment is a highly sensitive area for the vehicle's torsional stiffness. Therefore, the design of the ventilation cover mounting structure within the engine compartment plays a crucial role in the overall torsional stiffness of the vehicle. In related technologies, to ensure the torsional stiffness of the vehicle, traditional ventilation cover mounting structures employ multi-piece reinforced sheet metal structures and large flange supports. This results in cumbersome installation and assembly of the ventilation cover with generally poor support effectiveness. Other methods directly fix the ventilation cover to the lower air chamber partition, with both ends directly fixed to the wheel arch side beams on the left and right sides. This leads to a lack of a stable mounting foundation for the ventilation cover. Utility Model Content

[0004] In view of this, this application aims to provide a ventilation cover mounting bracket to provide a stable mounting base for the installation of ventilation covers in the front engine compartment of a vehicle.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0006] A ventilation cover mounting bracket includes a main frame; the main frame has a triangular front windshield lower crossbeam connecting bracket, and a left connecting arm and a right connecting arm extending from the two corners of the front windshield lower crossbeam connecting bracket in a direction away from the front windshield lower crossbeam connecting bracket, respectively.

[0007] The front windshield lower crossbeam connecting frame is formed by a left branch beam, a right branch beam, and a middle beam. The middle beam is located between the left connecting arm and the right connecting arm. The connection part of the left branch beam and the right branch beam is provided with a crossbeam connecting part for connecting the front windshield lower crossbeam. The ends of the left connecting arm and the right connecting arm are respectively provided with side beam connecting parts for connecting the wheel arch side beams on the corresponding sides.

[0008] Furthermore, the crossbeam connection includes a plurality of first connection holes spaced apart along the length of the lower crossbeam of the front windshield.

[0009] Furthermore, the ends of the left connecting arm and the right connecting arm each have a side beam connecting lug that protrudes toward the corresponding side of the wheel cover side beam. The side beam connecting lug can overlap with the corresponding side of the wheel cover side beam, and the side beam connecting part includes a second connecting hole provided on the side beam connecting lug.

[0010] Furthermore, the ends of the left connecting arm and the right connecting arm each have a shock absorber support connecting lug that protrudes toward the corresponding side of the shock absorber support. The shock absorber support connecting lug can overlap with the corresponding side of the shock absorber support, and the shock absorber support connecting lug is provided with a shock absorber support connecting hole for connecting the shock absorber support.

[0011] Furthermore, the main frame is integrally stamped from a metal sheet.

[0012] Furthermore, with the vertical line of the central beam as the axis of symmetry, the left branch beam, the right branch beam, the left connecting arm, and the right connecting arm are all symmetrically distributed.

[0013] Furthermore, the central beam, the left connecting arm, and the right connecting arm are arranged in the same reference plane, and the left branch beam and the right branch beam are inclined upward relative to the reference plane toward the rear of the vehicle.

[0014] Furthermore, the left connecting arm, the middle beam, and the right connecting arm are provided with a plurality of fixing holes at intervals for fixing the air chamber partition.

[0015] Furthermore, the ventilation cover mounting bracket also includes engine hood support brackets respectively disposed at the ends of the left connecting arm and the right connecting arm.

[0016] Compared with related technologies, this application has the following advantages:

[0017] (1) The ventilation cover mounting bracket of this application is a triangular front windshield lower crossbeam connecting bracket combined with the left connecting arm and the right connecting arm on both sides to form a main frame with a general "A" shaped frame structure. The connecting parts of the left branch beam and the right branch beam are located at the top of the main frame and can be reliably fixed to the front windshield lower crossbeam through the crossbeam connecting part. The side beam connecting parts at the ends of the left connecting arm and the right connecting arm can be reliably fixed to the wheel arch side beam on the corresponding side. In this way, a stable triangular support structure is formed between the left branch beam, the right branch beam and the middle beam, between the left half of the front windshield lower crossbeam, the left branch beam, the left connecting arm and the left wheel arch side beam, and between the right half of the front windshield lower crossbeam, the right branch beam, the right connecting arm and the right wheel arch side beam. This not only helps to improve the overall stability of the front structure of the vehicle, but also provides a solid installation foundation for the installation of the ventilation cover in the front engine compartment of the vehicle.

[0018] (2) The crossbeam connection part used to connect the lower crossbeam of the windshield is designed as a connection hole, which not only simplifies the processing method but also ensures reliable connection performance. By setting corresponding screw holes or mounting holes on the lower crossbeam of the windshield, the top of the main frame can be easily fixed to the lower crossbeam of the windshield using fastening bolts.

[0019] (3) By setting side beam connecting ears at the ends of the left and right connecting arms, and opening a second connecting hole on the side beam connecting ears as a side beam connecting part for connecting the wheel cover side beam, the combination of the overlapping method and the bolt connection method ensures the reliability of the connection between the two ends of the main frame and the corresponding side wheel cover side beam; at the same time, the form of the connecting hole also has the advantages of simple processing method and reliable connection performance, and the connection and assembly between the main frame and the wheel cover side beam can be easily completed by using fastening bolts.

[0020] (4) Shock absorber support connecting ears are set at the ends of the left and right connecting arms, which can effectively realize the overlapping and matching between the two ends of the main frame and the corresponding shock absorber supports, thus providing many support and connection points for the main frame, which is conducive to further improving the connection stability of the two ends of the main frame. The shock absorber support connecting ears also adopt the form of connecting holes. The fastening bolts are inserted into the shock absorber support connecting holes, which can conveniently and reliably fix the corresponding shock absorber supports. It has the advantages of simple structure and reliable connection performance.

[0021] (5) The main frame of the ventilation cover mounting bracket is made by using an integrated stamping process and metal sheet. This not only ensures the good structural strength of the main frame, but also has the technical advantage of mature and reliable processing technology.

[0022] (6) The main frame adopts a symmetrical structure. The crossbeam connection part of the left branch beam and the right branch beam can be located in the middle of the rear side of the main frame and can be fixed to the middle of the crossbeam under the front windshield. The layout of the entire main frame in the front engine compartment is also more regular, which can provide a balanced and reliable support effect for the ventilation cover.

[0023] (7) The left and right branch beams are set in an upward tilting manner, which is adapted to the height position of the crossbeam under the front windshield, so that the main frame can better meet the spatial distribution requirements of the top frame of the front cabin, and can provide more suitable installation support conditions for the installation of the ventilation cover.

[0024] (8) Multiple fixing holes are provided at intervals on the left connecting arm, right connecting arm and middle beam, providing good fixing conditions for setting the air chamber partition below the ventilation cover mounting bracket.

[0025] (9) An engine hood support frame is provided at the end of the left connecting arm and the right connecting arm, which can provide good support for the middle part of the side of the engine hood, overcoming the problem that the ends of the left connecting arm and the right connecting arm are located at a low position and there is a large gap between them and the engine hood; in addition, a buffer block can be provided at the top of the engine hood support frame, which can provide good buffering effect when the engine hood is closed, thereby reducing the noise during the engine hood closing process.

[0026] Another object of this application is to provide a vehicle equipped with the ventilation cover mounting bracket described in this application. The vehicle of this application possesses the technical advantages of the aforementioned ventilation cover mounting bracket. Attached Figure Description

[0048] Torsional stiffness is one of the important performance indicators for evaluating the strength and rigidity of a vehicle body structure. It reflects the vehicle's ability to resist torsional deformation during driving, especially on uneven roads or when subjected to lateral forces. Therefore, this indicator has a significant impact on the vehicle's handling stability, safety, comfort, and durability.

[0049] The front structure of the vehicle body, including the engine compartment, is a highly sensitive area for overall torsional stiffness. Therefore, the design of the ventilation hood mounting structure within the engine compartment plays a crucial role in the vehicle's torsional stiffness. In related technologies, to ensure overall vehicle torsional stiffness, traditional ventilation hood mounting structures employ multi-piece reinforced sheet metal structures and large flange supports. Alternatively, the ventilation hood is directly fixed to the lower air chamber partition, with both ends directly fixed to the wheel arch side beams on the left and right sides. However, in the above-mentioned ventilation hood mounting structures, the multi-piece reinforced sheet metal structures are heavy, assembly is cumbersome, and the support effect on the ventilation hood is generally poor. When the ventilation hood is directly fixed, the surrounding structural components provide poor support, and there is insufficient connection strength between the ventilation hood and the surrounding structural components, resulting in insufficient torsional stiffness in this area, which is detrimental to improving the overall vehicle's torsional stiffness and product competitiveness.

[0050] In view of the above-mentioned problems in the related technologies, this application innovatively proposes a brand-new ventilation cover mounting bracket, thereby providing a stable mounting base for the installation of ventilation covers in the front engine compartment of the vehicle.

[0051] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0052] An embodiment of the first aspect of this utility model provides a ventilation cover mounting bracket, applied to the installation of ventilation covers in the forward engine compartment; one exemplary structure is as follows: Figure 1 , Figure 2 and Figure 3 As shown.

[0053] Overall, the ventilation cover mounting bracket mainly includes a main frame 1. The main frame 1 has a triangular front windshield lower crossbeam connecting frame 10, and a left connecting arm 11 and a right connecting arm 12 extending from the two corners of the front windshield lower crossbeam connecting frame 10 away from the front windshield lower crossbeam connecting frame 10, respectively. The front windshield lower crossbeam connecting frame 10 is formed by a left branch beam 101, a right branch beam 102, and a central beam 100, with the central beam 100 located between the left connecting arm 11 and the right connecting arm 12. The left branch beam 101 and the right branch beam 102 form the other two sides of the triangle of the front windshield lower crossbeam connecting frame 10. The connection part of the left branch beam 101 and the right branch beam 102 is also provided with a crossbeam connecting part 15 for connecting the front windshield lower crossbeam 5. The ends of the left connecting arm 11 and the right connecting arm 12 are respectively provided with side beam connecting parts 16 for connecting the wheel arch side beams on the corresponding sides.

[0054] It should be noted that, based on the above-mentioned overall design concept, the technical solution of this application can adopt a variety of different specific implementation structures, forms, or configuration sequences. For example, the main frame 1 can be manufactured by integral stamping or by separate beams, which are then welded together to form the main frame 1. The crossbeam connection 15 and the side beam connection 16 can adopt various specific structural forms such as connecting holes, plug-in, and welding to achieve the corresponding beams. For parts required for the implementation of the overall solution but not covered in the above overall setup, reasonable and flexible designs can be made by referring to mature setup methods in the field and the actual situation during implementation, which will not be elaborated here. The specific implementation scheme described below in this embodiment is only one of the many solutions that can be formed by the above-mentioned combinations and variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the various solutions that can be formed by the above-mentioned combinations and variations, as well as the specific implementation scheme of this embodiment, are all within the protection scope of this application.

[0055] Still Figure 2 As shown, in some preferred exemplary embodiments, the crossbeam connecting portion 15 of this embodiment includes a plurality of first connecting holes 150 spaced apart along the length direction of the lower crossbeam 5 of the front windshield. Designing the crossbeam connecting portion 15 for connecting the lower crossbeam 5 of the front windshield as connecting holes not only simplifies the manufacturing process but also ensures reliable connection performance; by correspondingly providing screw holes or mounting holes on the lower crossbeam 5 of the front windshield, the top of the main frame 1 can be conveniently fixed to the lower crossbeam 5 of the front windshield using fastening bolts 20.

[0056] Furthermore, preferably, side beam connecting ears 13 protruding towards the corresponding wheel arch side beams can be provided at the ends of both the left connecting arm 11 and the right connecting arm 12, so that the side beam connecting ears 13 can overlap with the corresponding wheel arch side beams; based on the provision of the side beam connecting ears 13, the side beam connecting part 16 of this embodiment includes a second connecting hole 160 provided on the side beam connecting ears 13. The side beam connecting ears 13 at the end of the left connecting arm 11 are used to overlap and cooperate with the left wheel arch side beam 41 of the two wheel arch side beams, and the side beam connecting ears 13 at the end of the right connecting arm 12 are used to overlap and cooperate with the right wheel arch side beam 42 of the two wheel arch side beams, and a fastening bolt 20 is inserted into the second connecting hole 160 to achieve a fixed connection with the corresponding wheel arch side beam. By providing side beam connecting ears 13 at the ends of the left connecting arm 11 and the right connecting arm 12, and opening a second connecting hole 160 on the side beam connecting ears 13 as a side beam connecting part 16 for connecting the wheel cover side beam, the combination of the overlapping method and the bolted connection method ensures the reliability of the connection between the two ends of the main frame 1 and the corresponding side wheel cover side beam; at the same time, the form of the connecting hole also has the advantages of simple processing and reliable connection performance, and the connection and assembly between the main frame 1 and the wheel cover side beam can be easily completed by using fastening bolts 20.

[0057] Continue as Figure 2 As shown, in some preferred exemplary embodiments, the ends of the left connecting arm 11 and the right connecting arm 12 of this embodiment each have a shock absorber support connecting ear 14 protruding toward the corresponding side of the shock absorber support 7. The shock absorber support connecting ear 14 can overlap with the corresponding side of the shock absorber support 7, and the shock absorber support connecting ear 14 is provided with a shock absorber support connecting hole 140 for connecting the shock absorber support 7. By simultaneously setting shock absorber support connecting ears 14 at the ends of the left connecting arm 11 and the right connecting arm 12, the overlapping fit between the two ends of the main frame 1 and the corresponding shock absorber supports 7 can be well realized, thus providing many support and connection points for the main frame 1, which is conducive to further improving the connection stability of the two ends of the main frame 1. The shock absorber support connecting ears 14 also adopt the form of connecting holes. By using fastening bolts 20 to pass through the shock absorber support connecting holes 140, the corresponding shock absorber supports 7 can be conveniently and reliably fixed, which has the advantages of simple structure and reliable connection performance.

[0058] Regarding the specific processing of the main frame 1, as mentioned above, different processing methods can be adopted, such as integral stamping and separate processing and welding. When using separate welding, the beams in the main frame 1 can be processed from sheet metal or made from profiles such as square tubes and round tubes. However, in some preferred exemplary embodiments, the main frame 1 of this embodiment is integrally stamped from sheet metal. Using an integral stamping process to process the main frame 1 of the ventilation cover mounting bracket from sheet metal not only ensures the good structural strength of the main frame 1, but also has the technical advantage of mature and reliable processing technology.

[0059] Furthermore, the main frame 1 can be either asymmetrical or symmetrical. For example... Figure 2 As shown, in some preferred exemplary embodiments, with the vertical line of the central beam 100 as the axis of symmetry, the left branch beam 101 and right branch beam 102, as well as the left connecting arm 11 and right connecting arm 12, are symmetrically distributed. The main frame 1 adopts a symmetrical structure, and the crossbeam connecting part 15 at the connection between the left branch beam 101 and the right branch beam 102 can be located at the rear middle of the main frame 1, and can be fixed to the middle of the front windshield lower crossbeam 5. The arrangement of the entire main frame 1 in the front engine compartment is also more regular, which can provide a balanced and reliable support effect for the ventilation cover.

[0060] Continue as Figure 3 As shown, in some preferred exemplary embodiments, the central beam 100, left connecting arm 11, and right connecting arm 12 are arranged in the same reference plane, and the left branch beam 101 and right branch beam 102 are inclined upwards relative to the reference plane towards the rear of the vehicle. The degree of upward inclination can, of course, be flexibly adjusted within a reasonable range; preferably, the upward inclination angle of the plane containing the left branch beam 101 and right branch beam 102 relative to the reference plane can be set between 20° and 35°, that is, the angle α between the plane containing the left branch beam 101 and right branch beam 102 and the reference plane is 145°-165°. The upward inclination of the left branch beam 101 and right branch beam 102 is adapted to the height position of the lower crossbeam 5 of the windshield, allowing the main frame 1 to better meet the spatial distribution requirements of the top frame of the front engine compartment, and providing more suitable installation support conditions for the ventilation cover.

[0061] In addition, such as Figures 4 to 7 As shown, in some preferred exemplary embodiments, the left connecting arm 11, the middle beam 100 and the right connecting arm 12 of this embodiment are provided with a plurality of fixing holes 17 for fixing the air chamber partition 3 at intervals. Multiple fixing holes 17 are provided at intervals on the left connecting arm 11, the right connecting arm 12, and the middle beam 100, providing good fixing conditions for the air chamber partition 3 to be installed below the ventilation cover mounting bracket. The air chamber partition 3 installed in the front engine compartment can effectively isolate the engine, reducer and other components from the air conditioning unit. The location of the air chamber partition 3 is basically the same as the location of the left connecting arm 11, the middle beam 100 and the right connecting arm 12. Fixing holes 17 are opened on the above beams, and fastening bolts 20 can be passed through the fixing holes 17 and screwed to the top of the air chamber partition 3 to achieve fixed installation of the top of the air chamber partition 3. In order to improve the airtightness and sound insulation of the top of the air chamber partition 3, a gasket 30 can be added between the air chamber partition 3 and the main frame 1. The gasket 30 can be a sealing strip, soft pad, etc.

[0062] Meanwhile, auxiliary support structures can also be installed on the main frame 1. Specifically, the ventilation cover mounting bracket in this embodiment also includes engine hood support brackets 2 respectively located at the ends of the left connecting arm 11 and the right connecting arm 12. Installing engine hood support brackets 2 at the ends of the left connecting arm 11 and the right connecting arm 12 provides good support for the middle part of the engine hood side, overcoming the problem of the lower position of the ends of the left connecting arm 11 and the right connecting arm 12 and the increased gap between them and the engine hood. Furthermore, a buffer block can be installed on the top of the engine hood support bracket 2, which provides good cushioning when the engine hood is closed, thereby reducing the noise during the closing process.

[0063] In summary, the ventilation cover mounting bracket of this embodiment, the triangular front windshield lower crossbeam connecting bracket 10, and the left connecting arm 11 and right connecting arm 12 on both sides are combined into a main frame 1 with a generally "A" shaped frame structure. The connection parts of the left branch beam 101 and the right branch beam 102 are located at the top of the main frame 1 and can be reliably fixed to the front windshield lower crossbeam 5 through the crossbeam connecting part 15. The side beam connecting parts 16 at the ends of the left connecting arm 11 and the right connecting arm 12 can be reliably fixed to the wheel arch side beams on the corresponding sides. Firstly, a stable triangular support structure is formed between the left branch beam 101, the right branch beam 102, and the middle beam 100; between the left half of the lower crossbeam 5 of the front windshield, the left branch beam 101, the left connecting arm 11, and the left wheel arch side beam 41; and between the right half of the lower crossbeam 5 of the front windshield, the right branch beam 102, the right connecting arm 12, and the right wheel arch side beam 42. This not only helps to improve the overall stability of the front structure of the vehicle, but also provides a solid installation foundation for the installation of the ventilation cover in the front engine compartment of the vehicle.

[0064] An embodiment of the second aspect of this application provides a vehicle equipped with the ventilation cover mounting bracket provided in Embodiment 1. By incorporating the ventilation cover mounting bracket of this application into the front structure of the vehicle body, the vehicle can possess the technical advantages of the aforementioned ventilation cover mounting bracket.

[0065] refer to Figure 8 and Figure 9As shown, the front structure of the vehicle body includes a lower windshield crossbeam 5, wheel arch side beams extending forward from both ends of the lower windshield crossbeam 5, two engine compartment longitudinal beams 8 located on the left and right sides of the bottom of the engine compartment, a radiator upper crossbeam 6 connecting the front ends of the two wheel arch side beams, and a longitudinal beam side beam connecting plate 9 connecting the front ends of the wheel arch side beams and the engine compartment longitudinal beams 8 on the same side. The wheel arch side beams are typically designed as separate sections, including a side beam 400 arranged along the longitudinal direction of the vehicle and located above the wheels, and a front side connecting beam 401 connecting the front end of the side beam 400 and the end of the radiator upper crossbeam 6. Furthermore, shock absorber supports 7 are installed below the middle of the two side beams 400. Based on the overall layout of the aforementioned front structure of the vehicle body, the ventilation hood mounting bracket of this application can be set at the top position of the rear of the front engine compartment. The ends of the left connecting arm 11 and the right connecting arm 12 on the main frame 1 are respectively fixed to the wheel arch side beam and the shock absorber support 7 on the corresponding side. The connection parts of the left branch beam 101 and the right branch beam 102 are fixed to the lower crossbeam 5 of the front windshield through the crossbeam connection part 15, so that the ventilation hood mounting bracket becomes part of the front structure of the vehicle body. The setting of the ventilation hood mounting bracket in the front structure of the vehicle body can not only effectively enhance the overall structural strength and stability of the front structure of the vehicle body and provide a good and stable foundation for the installation of the ventilation hood, but also provide good support and buffering effect for the engine hood.

[0066] As can be seen, in the case of traditional ventilation cover mounting structures with multiple stacked and reinforced sheet metal structures and large flange support structures, the ventilation cover mounting frame of this application is adopted. Its main frame 1 is integrally stamped from a metal sheet, preferably aluminum sheet material, to form a multi-ring frame. At the same time, the shock absorber support connecting ears 14 at the ends of the left connecting arm 11 and the right connecting arm 12 are connected to the corresponding shock absorber support 7 to provide waist support and enhance the overall torsional stiffness. By investing minimal resources in local areas, the problem of weak torsional stiffness of the whole vehicle is solved. At the same time, the technical objectives of lightweight design and convenient manufacturing process are achieved, so that the ventilation cover and other structural components around the ventilation cover mounting frame can obtain good support, thereby forming a frame structure with high torsional stiffness.

[0067] The main frame 1, together with the surrounding frame structures such as the lower crossbeam 5 of the front windshield, the wheel arch side beams, and the shock absorber support 7, forms a series of triangular ring-shaped skeleton structures, which greatly improves the torsional stiffness, fatigue durability, lightweighting, and cost reduction of the front structure of the vehicle.

[0068] In specific implementation, it can be referred to Figure 8 as well as Figure 1 , Figure 2As shown, the specific structural scheme is as follows. The ventilation cover mounting bracket consists of three parts: a front windshield lower crossbeam connecting bracket 10 for connecting the front windshield lower crossbeam 5, a left connecting arm 11 for connecting the left wheel arch side beam 41, and a right connecting arm 12 for connecting the right wheel arch side beam 42. The left branch beam 101, the left half of the front windshield lower crossbeam 5, the left connecting arm 11, and the left wheel arch side beam 41 in the front windshield lower crossbeam connecting bracket 10 form a triangular ring structure. The right branch beam 102, the right half of the front windshield lower crossbeam 5, the right connecting arm 12, and the right wheel arch side beam 42 in the front windshield lower crossbeam connecting bracket 10 form a triangular ring structure. The front windshield lower crossbeam connecting bracket 10 itself also forms a triangular ring structure. The main frame 1, the left wheel arch side beam 41, the right wheel arch side beam 42, and the radiator upper crossbeam 6 also form a ring structure.

[0069] In this way, the combined effect of multiple closed triangular ring structures and a quadrilateral ring structure provides sufficient rigidity support to the vehicle body in both the Z and Y directions, ensuring that the front engine compartment has sufficient rigidity, minimizing torsional deformation, and guaranteeing the overall stability of the vehicle.

[0070] The main frame 1 is fixedly connected to the air chamber partition 3, wheel arch side beams, front windshield lower crossbeam 5, shock absorber support 7, etc., by welding or fastening bolts 20. The overall structure provides stronger support to the vehicle body in the Z and Y directions, reducing body deformation and improving the stability of the front engine compartment. On this basis, the main frame 1, wheel arch side beams, and radiator upper crossbeam 6 form a closed frame. The two ends of the radiator upper crossbeam 6 can also be connected to the corresponding side front connecting beam 401 by welding or bolting. The two ends of the radiator upper crossbeam 6 are also fixedly connected to the corresponding side engine compartment longitudinal beam 8 through the longitudinal beam side beam connecting plate 9, forming a box-shaped structure that provides sufficient rigidity and strength support to the front engine compartment and ensures the stability of the entire vehicle.

[0071] Overall, by setting up the ventilation hood mounting bracket, in conjunction with the surrounding lower windshield crossbeam 5, wheel arch side beams, shock absorber supports 7, radiator upper crossbeam 6, and engine compartment longitudinal beams 8, multiple closed ring-shaped support structures are formed. This crisscrossing frame provides excellent support for the vehicle body. The closed triangular and quadrilateral ring supports around the ventilation hood mounting bracket give the vehicle body good load-bearing capacity and resistance to deformation, maintaining the stability of the vehicle body structure. Compared to traditional sheet metal flanged and welded structures, this design offers greater stability, reduces the risk of failure due to poor durability, decreases the probability of fatigue cracks and damage, and increases the service life of the front structure of the vehicle body.

[0072] Meanwhile, the main frame 1 is made of aluminum sheet in one piece. While ensuring the strength of the vehicle body, it has lighter materials and thinner walls compared with traditional structures, thereby reducing the weight of the whole vehicle and improving the vehicle's fuel economy, acceleration performance and handling performance.
