[0002] In related technologies, the front frame of a vehicle needs to be equipped with multiple mounting points to accommodate various structures at the front of the vehicle, such as overflow tanks and hood locks. However, the design of multiple mounting points makes the front frame structure more complex and heavier. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a front-end frame assembly for a vehicle. According to this invention, the front-end frame assembly defines clearance holes for the longitudinal beams of the vehicle body and provides mounting positions for the anti-collision beams through the cooperation of a ring-shaped main frame and two side connecting parts, ensuring the stability of the front-end frame assembly. Furthermore, the entire front-end frame assembly is made of aluminum profiles, reducing weight while meeting structural strength requirements, thus achieving vehicle lightweighting.

Compared with the common steel front frame, the front frame assembly of this utility model is constructed of aluminum profiles, which can reduce the weight of the front frame assembly and achieve lightweighting. Compared with the common injection-molded front frame, aluminum profiles have good strength and toughness and can withstand various loads generated during vehicle operation, ensuring the safety performance of the vehicle. Therefore, the front frame assembly of this utility model can meet the requirements of lightweighting while ensuring the structural, functional, and performance requirements of the vehicle's front structure.

[0007] According to one embodiment of the present invention, the main frame includes: an upper crossbeam, a lower crossbeam, a left column, and a right column, wherein the upper crossbeam and the lower crossbeam are spaced apart in the height direction; the left column and the right column are connected between the upper crossbeam and the lower crossbeam and are respectively provided with a first side connecting part and a second side connecting part; wherein the upper crossbeam is provided with a first mounting sleeve, and the lower crossbeam is provided with a second mounting sleeve, wherein at least one of the second mounting sleeve and the first mounting sleeve is configured as a plurality of spaced apart in the width direction.

[0008] According to one embodiment of the present invention, the bottom of the upper crossbeam is formed with a support wall that extends in the front-rear direction and is inclined toward the lower crossbeam in the height direction. The projection of the support wall in the height direction is at least partially opposite to the lower crossbeam, and the first mounting sleeve is disposed on the support wall.

[0009] According to one embodiment of the present invention, the upper ends of the first side connecting portion and the upper ends of the second side connecting portion are respectively lower than the upper crossbeam, and the left and right ends of the upper crossbeam are respectively provided with first diagonal bracing beams between the first side connecting portion and the second side connecting portion.

[0010] According to one embodiment of the present invention, the front frame assembly further includes: a hood lock mounting bracket, which is disposed on the upper crossbeam and located in the middle of the upper crossbeam.

[0011] According to one embodiment of the present invention, the front frame assembly further includes an overflow bottle mounting bracket, which is disposed on the upper crossbeam and located on one side of the upper crossbeam in the width direction.

[0012] According to one embodiment of the present invention, the front frame assembly further includes: a second diagonal brace, wherein there are two second diagonal braces, which are respectively disposed on both sides of the lower crossbeam in the width direction.

[0014] According to one embodiment of the present invention, the bottom ends of the first outer column and the second outer column are respectively provided with lower protective plate mounting plates.

[0015] The following is a brief description of the vehicle body component according to this utility model.

[0016] The vehicle body assembly of this utility model includes a body body and a front frame assembly. The body body has a left longitudinal beam and a right longitudinal beam. Two clearance holes on the front frame assembly are respectively fitted onto the outer periphery of the left and right longitudinal beams. Therefore, during assembly, the left and right longitudinal beams can respectively engage with the two clearance holes on the front frame assembly, forming a tight integral structure between the front frame and the left and right longitudinal beams of the body body. During vehicle operation, whether subjected to frontal collision forces, lateral impact forces, or vertical bumps, the front frame and longitudinal beams can jointly bear and transmit these external forces, effectively dispersing stress and avoiding structural damage caused by localized stress concentration, significantly improving the overall structural stability and strength of the vehicle body assembly. The clearance hole design of the front frame assembly allows for a tight fit between the front frame assembly and the left and right longitudinal beams of the body body, achieving effective utilization of the front space of the vehicle body and providing more space for the arrangement of other vehicle components (such as the engine, transmission, and suspension system), which is beneficial to the overall vehicle layout. Furthermore, since the front frame assembly is made of aluminum profiles, the weight of the entire vehicle body assembly can be reduced, achieving lightweighting.

Through the avoidance hole and cooperation with the longitudinal beam of the vehicle body, the overall stability of the vehicle body structure is further improved. Moreover, the front frame assembly is made of aluminum profile, which can reduce the weight of the whole vehicle and realize the lightweighting of the vehicle.

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0034] In related technologies, the front frame of a vehicle needs to be equipped with multiple mounting points to accommodate various structures at the front of the vehicle, such as overflow tanks and hood locks. However, the design of multiple mounting points makes the structure of the front frame more complex and inevitably increases the weight of the front frame.

[0035] The following is for reference. Figures 1-3 This invention describes a front-end framework component according to an embodiment of the present invention.

[0036] The front-end frame assembly 1 according to this utility model includes: a main frame 11, a first side connecting part 12, and a second side connecting part 13. The main frame 11 is ring-shaped. The first side connecting part 12 and the second side connecting part 13 are respectively disposed on both sides of the main frame 11 in the width direction. The first side connecting part 12 and the second side connecting part 13 are respectively formed with avoidance holes 141 for avoiding longitudinal beams. The first side connecting part 12 and the second side connecting part 13 are respectively formed with mounting holes 142 for connecting anti-collision beams. The mounting holes 142 are arranged on the outer periphery of the avoidance holes 141. Among them, at least one of the main frame 11 and the first side connecting part 12 and the second side connecting part 13 is made of aluminum profile.

[0037] The front-end frame component 1 of this utility model is configured with a main frame 11, such as... Figures 1-3As shown, the main frame 11 is constructed in a ring shape. The ring-shaped main frame 11 has good structural stability and load-bearing capacity, providing sufficient strength and rigidity for the front frame, effectively resisting various forces and impacts during vehicle operation, and ensuring the stability and safety of the vehicle's front structure. The first side connecting part 12 and the second side connecting part 13 are connected to the main frame 11 on both sides of the main frame 11 in the width direction, respectively. During assembly, the first side connecting part 12 and the second side connecting part 13 can also be connected to the vehicle body. The connection between the first side connecting part 12 and the second side connecting part can further enhance the overall stability of the front frame assembly 1 after assembly with the vehicle body. The first side connecting part 12 and the second side connecting part are respectively formed with avoidance holes 141 for avoiding the longitudinal beams of the vehicle body. During assembly, the ends of the longitudinal beams of the vehicle body can pass through the avoidance holes 141 on the first side connecting part 12 and the second side connecting part 13, avoiding interference of the longitudinal beams of the vehicle body with the front frame assembly 1. Moreover, after the longitudinal beams pass through the avoidance holes 141, a limit can be formed between them and the avoidance holes 141, further improving the stability of the front frame assembly 1 assembly. Meanwhile, the first side connecting part 12 and the second side connecting part 13 are respectively provided with mounting holes 142 for installing the anti-collision beam on the outer periphery of the corresponding clearance hole 141. During assembly, the anti-collision beam can be assembled by fasteners (such as bolts) cooperating with the mounting holes 142. At this time, the vehicle longitudinal beam can also directly cooperate with the anti-collision beam after passing through the clearance hole 141, realizing the stable installation of the anti-collision beam. This allows the front frame to achieve good connection and cooperation with the vehicle's longitudinal beam and anti-collision beam, ensuring the reliability of the connection between the vehicle's front components.

[0038] Furthermore, the main frame 11, the first side connecting part 12, and the second side connecting part 13 can all be made of aluminum profiles. For example, the main frame 11 can be extruded from aluminum profiles, and the first side connecting part 12 and the second side connecting part 13 can be connected and fixed to the main frame 11 by inert gas shielded welding (or riveting, etc.). Compared with the common steel front frame, the front frame assembly 1 of this utility model is constructed of aluminum profiles, which can reduce the weight of the front frame assembly 1 and achieve lightweighting. Compared with the common injection-molded front frame, aluminum profiles have good strength and toughness and can withstand various loads generated during vehicle operation, ensuring the safety performance of the vehicle. Therefore, the front frame assembly 1 of this utility model can meet the requirements of lightweighting while ensuring the structural, functional, and performance requirements of the vehicle's front structure.

[0039] Moreover, aluminum profile extrusion dies have low development costs and are easy to maintain and cut. Therefore, the front-end frame component 1 can be expanded and developed on different models on the same platform. When facing different models, only some structures need to be appropriately adjusted without the need to open new dies. For example, when the platform for designing the front-end frame component 1 of a regular sedan needs to process the front-end frame component 1 of an SUV, only the Y and X dimensions of the front-end frame component 1 need to be adjusted. Except for the parts with changed geometric dimensions, other parts can be reused without replacing the dies. This can achieve a high commonality rate before and after the platform model evolution, greatly reducing the dies development cost and platform expansion cost, improving platform commonality, and facilitating standardized production and cost control for enterprises.

[0040] According to one embodiment of the present invention, the main frame 11 includes: an upper crossbeam 111, a lower crossbeam 112, a left column 113, and a right column 114. The upper crossbeam 111 and the lower crossbeam 112 are spaced apart in the height direction. The left column 113 and the right column 114 are connected between the upper crossbeam 111 and the lower crossbeam 112 and are respectively provided with a first side connecting part 12 and a second side connecting part 13. The upper crossbeam 111 is provided with a first mounting sleeve 151, and the lower crossbeam 112 is provided with a plurality of second mounting sleeves 152. At least one of the second mounting sleeves 152 and the first mounting sleeves 151 is configured as a plurality of spaced apart in the width direction.

[0041] like Figures 1-3 As shown, the main frame 11 consists of an upper crossbeam 111, a lower crossbeam 112, a left column 113, and a right column 114. The upper crossbeam 111 and the lower crossbeam 112 are spaced apart in the height direction. The left column 113 and the right column 114 are respectively positioned between the two crossbeams and can support the upper crossbeam 111 in the height direction. This gives the entire main frame 11 good structural stability and load-bearing capacity in three-dimensional space, effectively resisting forces and impacts from different directions during vehicle operation, and ensuring the integrity and safety of the vehicle's front-end structure. Meanwhile, the left column 113 is provided with a first side connection part 12, and the right column 114 is provided with a second side connection part 13. Through the cooperation of the two side connection parts with the vehicle body, the connection stability between the main frame 11 and the vehicle body can be enhanced. The upper crossbeam 111 is provided with a first mounting sleeve 151, and the lower crossbeam 112 is provided with a second mounting sleeve 152. The first mounting sleeve 151 and the second mounting sleeve 152 can cooperate with each other to assemble and fix the suspension. During processing, the number of the first mounting sleeve 151 and the second mounting sleeve 152 can be designed according to actual needs.

[0042] In some embodiments, a plurality of first mounting sleeves 151 spaced apart in the width direction can be provided on the upper crossbeam 111, and a plurality of second mounting sleeves 152 spaced apart in the width direction can be provided on the lower crossbeam 112. Moreover, the second mounting sleeves 152 and the corresponding first mounting sleeves 151 are correspondingly provided in the height direction. The first mounting sleeves 151 and the second mounting sleeves 152 provide a precise installation position for the vehicle radiator, ensuring that the radiator can be accurately and stably installed on the front end frame. At the same time, by adopting the method of corresponding first mounting sleeves 151 and second mounting sleeves 152, four-point suspension assembly and fixation can be achieved, reducing the impact of vibration during vehicle operation on the radiator and improving the safety of the radiator.

[0043] In some embodiments, when the suspension to be fixed is a three-point suspension, the position and quantity of the first mounting sleeve 151 and the second mounting sleeve 152 can be adaptively designed according to the actual situation. In this case, the first mounting sleeve 151 and the second mounting sleeve 152 can be misaligned in the height direction.

[0044] According to one embodiment of the present invention, the upper end of the first side connecting portion 12 and the upper end of the second side connecting portion 13 are respectively lower than the upper crossbeam 111, and the left and right ends of the upper crossbeam 111 are respectively provided with first diagonal bracing beams 161 between the first side connecting portion 12 and the second side connecting portion 13. Figures 1-3 As shown, the upper ends of the first side connecting part 12 and the second side connecting part 13 are respectively lower than the upper crossbeam 111, which allows for a clearance space at the end of the upper crossbeam 111, facilitating the arrangement of the vehicle's front-end components. During assembly, operators can more easily install and adjust related components, reducing assembly difficulty and time, and improving production efficiency. First diagonal bracing beams 161 are respectively installed between the left and right ends of the upper crossbeam 111 and the first side connecting part 12 and the second side connecting part 13, forming a stable triangular support structure. This not only improves the structural strength of the front-end frame assembly 1 itself, but the triangular structure also has extremely high stability, effectively resisting lateral and torsional forces, enhancing the structural stability of the front-end frame under complex working conditions. For example, when the vehicle turns or makes an emergency maneuver, the first diagonal bracing beam 161 can provide additional support to prevent the frame from deforming or being damaged, ensuring the vehicle's safety performance.

[0045] According to one embodiment of the present invention, a support wall 1111 extending in the front-rear direction and inclined towards the lower crossbeam 112 in the height direction is formed at the bottom of the upper crossbeam 111. The projection of the support wall 1111 in the height direction is at least partially opposite to the lower crossbeam 112, and the first mounting sleeve 151 is disposed on the support wall 1111. Figure 1As shown, a support wall 1111 is provided at the bottom of the upper crossbeam 111. The support wall 1111 is inclined. The projection of the inclined support wall 1111 in the height direction is at least partially opposite to the lower crossbeam 112. Since the first mounting sleeve 151 protrudes towards the front of the upper crossbeam 111, and it is necessary to ensure that the first mounting sleeve 151 corresponds to the second mounting sleeve 152 in the height direction when assembling the suspension, the first mounting sleeve 151 can be set on the support wall 1111. The inclined support wall 1111 can form a certain clearance space, so that the protruding first mounting sleeve 151 can correspond to the second mounting sleeve 152 in the height direction, ensuring that the suspension can be assembled normally and improving the stability of the first mounting sleeve 151 and the second mounting sleeve 152 in the suspension assembly.

[0046] According to one embodiment of this utility model, the front frame assembly 1 further includes a hood lock mounting bracket 171, which is disposed on the upper crossbeam 111 and located in the middle of the upper crossbeam 111. The hood lock mounting bracket 171 provides a stable mounting position for the hood lock, ensuring that the hood lock can be reliably installed on the front frame, realizing the normal opening and closing function of the hood and meeting the basic usage requirements of the vehicle. By placing the hood lock mounting bracket 171 on the upper crossbeam 111 and located in the middle of the upper crossbeam 111, the space of the upper crossbeam 111 is fully utilized, making the installation position of the hood lock more reasonable. This not only avoids affecting the installation and layout of other vehicle components, but also ensures the stability and reliability of the hood lock during use, avoiding problems such as loosening or falling off of the hood lock due to improper installation position.

[0047] According to one embodiment of this utility model, the front frame assembly 1 further includes an overflow tank mounting bracket 172, which is disposed on the upper crossbeam 111 and located on one side of the upper crossbeam 111 in the width direction. The overflow tank mounting bracket 172 provides a dedicated mounting position for the overflow tank, ensuring that the overflow tank can be securely installed on the front frame, realizing its normal function of storing and discharging excess coolant in the vehicle cooling system, and meeting the basic usage requirements of the vehicle cooling system. By placing the overflow tank mounting bracket 172 on the upper crossbeam 111 and located on one side of the upper crossbeam 111 in the width direction (which may be located between the hood lock mounting bracket 171 and the first mounting sleeve 151), the unused space of the upper crossbeam 111 is fully utilized, making the installation position of the overflow tank more reasonable. This not only avoids affecting the installation and layout of other key vehicle components (such as mounting sleeves, hood locks, etc.), but also ensures the stability and reliability of the overflow tank during use, avoiding problems such as overflow tank shaking and leakage caused by improper installation position.

[0048] According to one embodiment of the present invention, the front-end frame assembly 1 further includes: two second diagonal bracing beams 162, which are respectively disposed on both sides of the lower crossbeam 112 in the width direction. One end of one second diagonal bracing beam 162 is connected to the front edge of the lower crossbeam 112, and the other end is connected to the front side of the left column 113; one end of the other second diagonal bracing beam 162 is connected to the front edge of the lower crossbeam 112, and the other end is connected to the front side of the right column 114. Figures 1-3 As shown, the front frame assembly 1 also includes two second diagonal bracing beams 162. These two beams are arranged on both sides of the lower crossbeam 112 in the width direction. One beam connects to the lower crossbeam 112 and the front side of the left column 113 at both ends, while the other beam connects to the lower crossbeam 112 and the front side of the right column 114 at both ends. These two beams strengthen the connection between the two columns and the lower crossbeam 112. During vehicle operation, the front frame is subjected to forces and impacts from different directions, especially frontal collision forces. The presence of beam 162 alters the stress distribution pattern of the traditional front-end frame. When the front of the vehicle is impacted, the second diagonal brace beam 162 can absorb some of the collision energy. At the same time, the structure of the lower crossbeam 112 and the left and right columns 114 can also work together to further disperse and absorb energy, so that the stress borne by the lower crossbeam 112 and the left and right columns 114 can be more evenly distributed throughout the entire frame structure, avoiding stress concentration in a certain local area. This improves the impact resistance of the entire front-end frame assembly 1, reduces the impact of collisions on the vehicle's passenger compartment, and improves the vehicle's safety performance.

[0049] Furthermore, the arrangement of the two second diagonal braces 162 forms a stable triangular support structure. Triangular structures possess extremely high stability. The two second diagonal braces 162 connect the lower crossbeam 112 to the left column 113 and the right column 114 respectively, effectively enhancing the structural stability of the front frame in the width direction. During emergency braking or a collision, the second diagonal braces 162 provide additional support to prevent frame deformation or damage, ensuring vehicle safety.

[0050] According to one embodiment of the present invention, the first side connecting part 12 includes: a first mounting plate 121, a second mounting plate 122 and a first outer column 123. The first mounting plate 121 and the second mounting plate 122 are arranged in parallel and one end is respectively connected to the left column 113; the first outer column 123 is respectively connected to the other end of the first mounting plate 121 and the second mounting plate 122 and forms an avoidance hole 141.

[0051] The second side connection part 13 includes: a third mounting plate 131, a fourth mounting plate 132, and a second outer column 133. The third mounting plate 131 and the fourth mounting plate 132 are arranged in parallel and one end is connected to the right column 114 respectively. The second outer column 133 is connected to the other end of the third mounting plate 131 and the fourth mounting plate 132 respectively and forms an avoidance hole 141.

[0052] like Figures 1-3 As shown, in the first side connecting part 12, the first mounting plate 121 and the second mounting plate 122 are arranged in parallel and one end is connected to the left column 113 respectively. In the second side connecting part 13, the third mounting plate 131 and the fourth mounting plate 132 are arranged in parallel and one end is connected to the right column 114 respectively. The multi-plate connection method significantly enhances the connection strength between the left and right columns 114 and the two side connecting parts, so that each part of the front frame can better bear and transmit stress when subjected to various external forces, thereby improving the structural stability of the entire front frame. The first outer pillar 123 is connected to the other end of the first mounting plate 121 and the second mounting plate 122, forming a clearance hole 141. The second outer pillar 133 is connected to the other end of the third mounting plate 131 and the fourth mounting plate 132, forming another clearance hole 141. The two clearance holes 141 can respectively avoid the left and right longitudinal beams of the vehicle body, preventing interference between the front frame assembly 1 and the vehicle body longitudinal beams. Moreover, during assembly, the ends of the left and right longitudinal beams of the vehicle body can pass through the clearance holes 141. At this time, mounting holes 142 can be provided on the four mounting plates, and the vehicle bumper can be simultaneously fixed with the four mounting plates and the two longitudinal beams of the vehicle body, improving the stability of the assembly of the front frame assembly 1 and the bumper. In addition, the setting of the first outer pillar 123 and the second outer pillar 133 further enhances the overall strength and rigidity of the connection. During vehicle operation, the outer pillars can effectively resist lateral forces and torsional forces, preventing the connection from twisting or breaking due to excessive force, ensuring the stability and reliability of the front frame.

[0053] According to one embodiment of this utility model, a lower guard plate mounting plate is respectively provided at the bottom end of the first outer pillar 123 and the second outer pillar 133. The mounting plates on the bottom ends of the first outer pillar 123 and the second outer pillar 133 provide a stable mounting base for the lower guard plate. As an important protective component at the front of the vehicle, the lower guard plate effectively prevents road stones, mud, and other debris from impacting and corroding vehicle chassis components (such as the engine oil pan and transmission). The mounting plates ensure that the lower guard plate can be firmly installed on the front frame, enhancing the reliability of protection, reducing the risk of chassis component damage due to external factors, and extending the service life of the vehicle chassis components.

[0054] In some embodiments, the front-end frame assembly 1 can be mounted on the vehicle body, which typically has a left longitudinal beam and a right longitudinal beam. The two clearance holes 141 on the front-end frame assembly 1 can be respectively fitted onto the outer periphery of the left and right longitudinal beams. Therefore, during assembly, the left and right longitudinal beams can respectively engage with the two clearance holes 141 on the front-end frame assembly 1, forming a tight integral structure between the front-end frame and the left and right longitudinal beams of the vehicle body. During vehicle operation, whether subjected to frontal collision forces, lateral impact forces, or vertical bump forces, the front-end frame and longitudinal beams can jointly bear and transmit these external forces, effectively dispersing stress and avoiding structural damage caused by localized stress concentration, significantly improving the overall structural stability and strength of the vehicle body. The clearance hole 141 design of the front-end frame assembly 1 allows for a tight fit between the front-end frame assembly 1 and the left and right longitudinal beams of the vehicle body, achieving effective utilization of the front-end space of the vehicle body and providing more space for the arrangement of other vehicle components (such as the engine, transmission, suspension system, etc.), which is beneficial to the overall layout of the vehicle. Furthermore, since the front frame component 1 is made of aluminum profiles, the weight of the entire vehicle body can be reduced, achieving lightweighting.

[0055] The vehicle according to this utility model is briefly described below.

[0056] The vehicle according to this utility model includes the front frame assembly 1 in the above embodiments. Since the vehicle according to this utility model is equipped with the front frame assembly 1 in the above embodiments, the front frame assembly 1 cooperates with the main frame 11 through the first side connecting part 12 and the second side connecting part 13 to form a stable structure and provides mounting points for the bumper assembly.
