Description

Technical Field

[0001] This invention belongs to the field of automotive technology. Specifically, this invention relates to a headlight frame structure and a vehicle. Background Technology

[0002] like Figures 6 to 11 As shown, the existing automotive headlight frame structure mainly consists of five parts: the upper crossbeam section of the radiator, the radiator pillar, the connecting bracket plate, the front section baffle of the radiator frame, and the front section side plate of the radiator frame. The headlight frame assembly is formed by welding these five parts together. However, this method suffers from poor overall integrity, low precision in welding development, high tooling development costs, and a risk of weld tearing.

[0003] Existing models typically employ a multi-part welded headlight frame assembly structure. This results in a long product design and development cycle, complex structural design for each part, weak structural strength, increased vehicle weight due to the pre-reserved welding surfaces between parts, welding deformation issues, poor part precision due to multi-stage tooling development, and tearing of weld points during frontal collisions. Consequently, the headlight frame assembly has a long development cycle, high development costs, poor assembly precision, and increased vehicle weight.

[0004] An improved headlight frame structure is provided, particularly regarding how to reduce the number of parts, improve the overall integrity of the parts, and achieve a reduction in the number of parts. Summary of the Invention

Detailed Implementation

[0031] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," and similar expressions used in this document are for illustrative purposes only.

[0033] It should be noted that in the following embodiments, the terms "first", "second", "third" and "fourth" do not represent an absolute distinction in structure and / or function, nor do they represent the order of execution, but are merely for the convenience of description.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] Firstly, such as Figures 1 to 5 As shown, this embodiment of the invention provides a headlight frame structure, which consists of a headlight frame body and an upper crossbeam section 2. The headlight frame body is provided with a lamp holder to accommodate the headlight. The upper crossbeam section 2 is welded to the top connecting part 3 of the headlight frame body to form a double-layer sheet metal overlap structure. The number of Z-direction welding points in the double-layer sheet metal overlap structure is not less than 5.

[0036] Specifically, in this embodiment of the invention, the headlight frame structure is installed in the front compartment of the vehicle, and the vehicle's headlights are installed in the lamp holders. In this embodiment, the original product structure is integrated and optimized, reducing the number of assembly parts from five to two, improving the overall integrity of the parts, enhancing structural performance and strength, reducing the number of assembly parts, shortening the early development cycle, reducing the problem of welding and matching between multiple parts, solving the problem of poor precision in the original multi-part welded headlight frame assembly, and effectively reducing the weight of the headlight frame assembly. This provides effective support for weight reduction, cost reduction, and structural performance improvement in the engine compartment assembly.

[0037] In this embodiment of the invention, the original connecting bracket plate structure is cancelled and optimized. The design scheme is changed to a direct welding scheme between the upper crossbeam section 2 and the headlight frame body, which effectively solves the problem of insufficient welding strength between multiple parts. The upper part adopts a radiator column and the front side plate structure of the radiator frame for connection, which effectively solves the problem of changing the original single-layer sheet metal connection of the upper crossbeam section 2 to a double-layer sheet metal connection. Welding points are added at the Z-direction welding point position, increasing the original 1 welding point to 5, which effectively solves the problem of insufficient strength after welding the upper part of the headlight frame to the upper crossbeam section 2. The problem of insufficient Z-direction strength of the original headlight frame structure is effectively improved. The original front baffle design structure of the radiator frame is cancelled in the lower part. The radiator column and the front side plate of the radiator frame are connected as a whole, which reduces the number of parts developed and eliminates the welding between parts. In the headlight frame design process, the original structural problems are absorbed and optimized. The structural problems are improved in the new design scheme, the weak points are reinforced, the excessive strength is weakened, the original reinforcing rib structure design is changed, and the structure is reinforced with a free-form reinforcement throughout. Strengthening ribs to prevent rib breakage during a frontal collision enhances strength. Lateral reinforcing ribs are added to the lower part of the component, with the rib depth increased to 6mm (2 times the original depth). The lower edge strength of the component is significantly improved. Large notches are added in areas where strength is not critical, reducing the weight of the headlight frame component. The overall structural design optimizes the radiator column's structural strength, changing the original "U"-shaped beam design. A deep flange structure is adopted on one side of the component, with a stepped feature added to the flange location to increase the load-bearing capacity on one side. The direct force transmission design makes the product's structural structure stronger. The original "U"-shaped inner welding edge has been eliminated, optimizing the excessive structural performance in this area and replacing it with a flexible design. An extended reinforcing rib design has been added to the lamp socket cycle, strengthening the original lamp socket where reinforcement was needed and weakening other areas where structural strength was not required. This effectively improves the structural performance of the headlight frame assembly. The optimized product structure design also effectively increases the headlight installation and operation space, effectively solving the problem of insufficient installation and operation space caused by the original structure's inadequate structural performance.

[0038] In this embodiment of the invention, by optimizing the connection form between the original radiator upper crossbeam segment 2 and the radiator column and the front side plate of the radiator frame, the structure of the radiator column and the front side plate of the radiator frame is changed to an integral structure. The headlight frame is directly welded to the upper crossbeam segment 2 to form an integral connection structure. This optimizes the problem of insufficient Z-direction welding surface connection in the original structure. The original upper connection design of the headlight frame is modified by adding a flange at the top to reinforce and increase the Z-direction welding connection area between the headlight frame and the upper crossbeam segment 2. The original Z-direction connection structure with only one welding point is changed to five Z-direction welding connection points. The X-direction connection point position between the headlight frame and the upper crossbeam segment 2 is increased, thus improving the problem of insufficient Z-direction connection points between the headlight frame and the upper crossbeam segment 2. After the headlight frame was changed to an integrated structure, the performance and structural strength of individual parts were significantly improved. This effectively improved the original solution that required excessive structural strength of the upper crossbeam section 2, making the structural design of the upper crossbeam section 2 simple. The part itself does not need more structural features to optimize the structural strength of the product. The overlapping positions on both sides of the part are simplified, and the precision of individual parts is significantly improved, which can better match and overlap with the upper crossbeam of the radiator and the side longitudinal beam of the engine compartment.

[0039] By optimizing the complex design of the original upper crossbeam section 2, the design of the new upper crossbeam section 2 is simplified, improving the matching time in the early design and development process. The overall design of the parts is flattened, and the cross-sectional width is adjusted to be consistent, which helps to solve the difficulties in part forming, reduces the later part debugging cycle, and shortens the development and design time. The number of installation point features on the top surface is reduced, and the avoidance gaps on both sides of the side wall are eliminated, effectively solving the problem of part cracking at the gap under Z-direction stress in the original structure. The gaps on the side wall of the part structure are completely eliminated, improving its own structural strength. The length of the X-direction flange of the front is increased, improving the overall structural strength of the product in the Z-direction, effectively solving the problem of insufficient structural strength of the original radiator upper crossbeam. The simplification of the product structure effectively improves the individual part accuracy and welding accuracy. The overlapping position of the two ends of the parts is simplified and changed to a flat overlapping structure with a shortened overlapping length, which significantly improves the individual part accuracy at the overlapping interface of the two ends of the parts, and can better match and overlap with the radiator upper crossbeam and the engine compartment side longitudinal beam.

[0040] like Figure 1 and Figure 5As shown, the headlight frame body is a stamped sheet metal part. The headlight frame body also includes a first body part 4, a second body part 5, a third body part 6, and a fourth body part 7 connected in sequence. The top connecting part 3, the first body part 4, the second body part 5, the third body part 6, and the fourth body part 7 are integrally formed. The first body part 4 and the fourth body part 7 are arranged opposite to each other. The second body part 5 and the third body part 6 are arranged opposite to the top connecting part 3. The lamp holder is formed by the top connecting part 3, the first body part 4, the second body part 5, the third body part 6, and the fourth body part 7. The first body part 4, the second body part 5, the third body part 6, and the fourth body part 7 are located below the top connecting part 3. The top connecting part 3 is located below the upper crossbeam section 2.

[0041] In embodiments of the present invention, such as Figure 1 and Figure 5 As shown, the width of the second body part 5 is smaller than the width of the third body part 6. One end face of the second body part 5 in the width direction is flush with one end face of the third body part 6 in the width direction. The other end face of the second body part 5 in the width direction is flush with one end face of the first body part 4 in the length direction. The other end face of the third body part 6 in the width direction is flush with one end face of the fourth body part 7 in the length direction. The other ends of the first body part 4 and the other ends of the fourth body part 7 in the length direction are respectively aligned with and fixedly connected to the two ends of the top connecting part 3 in the length direction. The length directions of the first body part 4, the fourth body part 7, the second body part 5, and the third body part 6 are parallel to the Z-direction. The length directions of the second body part 5 and the third body part 6 are parallel to the Y-direction. One end of the second body part 5 in the length direction is fixedly connected to one end of the third body part 6 in the length direction. The other end of the second body part 5 in the length direction is fixedly connected to the lower end of the first body part 4. The other end of the third body part 6 in the length direction is fixedly connected to the lower end of the fourth body part 7. The X-axis is parallel to the length of the car body, the Y-axis is parallel to the width of the car body, and the Z-axis is perpendicular to both the X and Y axes. The second body part 5 and the third body part 6 are located below the lamp holder. The top surface of the second body part 5 is flush with the top surface of the third body part 6, and there is a certain distance between the bottom surface of the second body part 5 and the bottom surface of the third body part 6. The height of the bottom surface of the second body part 5 is less than the height of the bottom surface of the third body part 6, thus forming a notch below the third body part 6 and to the side of the second body part 5. This achieves weight reduction while meeting structural strength requirements. The CAE analysis results are as follows: Figure 12 As shown.

[0042] In embodiments of the present invention, such as Figure 1 and Figure 5As shown, the top connecting part 3 includes an upper connecting part 8 and an upper flange 9 connected together. The upper flange 9 is welded to the upper crossbeam section 2 and the two fit together. The upper connecting part 8 is connected to the first body part 4 and the fourth body part 7. One end of the upper flange 9 is fixedly connected to the upper end of the upper connecting part 8. The lamp holder is located below the upper connecting part 8. The upper connecting part 8 is located between the first body part 4 and the fourth body part 7. The two ends of the upper connecting part 8 in the length direction are fixedly connected to the upper ends of the first body part 4 and the fourth body part 7, respectively. The upper crossbeam section 2 is a sheet metal part. The upper crossbeam section 2 is welded to the upper flange 9 to form a double-layer sheet metal overlapping structure. The upper flange 9 and the upper crossbeam section 2 have 5 welding points, which are arranged sequentially along the length direction of the upper crossbeam section 2 to effectively improve the connection strength.

[0043] In embodiments of the present invention, such as Figure 1 and Figure 5 As shown, a first reinforcing rib 10 and a second reinforcing rib 11 are provided on the second body part 5, and a third reinforcing rib 12 is provided on the third body part 6. The two ends of the second reinforcing rib 11 are connected to the ends of the first reinforcing rib 10 and the third reinforcing rib 12, respectively. The first reinforcing rib 10 extends along the length direction of the second body part 5, the second reinforcing rib 11 extends along the width direction of the second body part 5, and the third reinforcing rib 12 extends along the length direction of the third body part 6. The first reinforcing rib 10 is located near the lower end of the second body part 5. The first reinforcing rib 10, the second reinforcing rib 11, and the third reinforcing rib 12 are continuously arranged to form a continuous reinforcing rib, avoiding the design of broken ribs. When a frontal collision occurs, the strength here is improved. The addition of lateral force-bearing reinforcing ribs at the lower part of the part can significantly improve the strength of the lower edge of the headlight frame body. Compared with the "broken ribs" of traditional dispersed parts, the continuous rib structure forms a through force transmission channel, which can effectively transmit the impact force during a frontal collision and avoid stress concentration fracture caused by broken ribs. Furthermore, the headlight frame body has fewer parts, and the reinforcing ribs can be continuously arranged along the optimal stress path, making it easy to process.

[0044] In embodiments of the present invention, such as Figure 1 and Figure 5 As shown, the third reinforcing rib 12 extends to the fourth body portion 7, that is, the third reinforcing rib 12 is provided to extend along the entire length of the third body portion 6.

[0045] In this embodiment of the invention, the depth of the first reinforcing rib 10, the second reinforcing rib 11 and the third reinforcing rib 12 is set to 6mm. By locally deepening the ribs, the maximum strength is achieved with the minimum material increment, which solves the problem of insufficient strength in weak areas of traditional equal-depth ribs.

[0046] In embodiments of the present invention, such as Figure 1 and Figure 5As shown in the figure, the first body part 4 includes a first upright post 13, a first connecting surface 14 connected to the first upright post 13, and a first flanging surface 15 connected to the first connecting surface 14. The first connecting surface 14 is located between the first upright post 13 and the first flanging surface 15. A first upper reinforcing rib 16 is provided on the first upright post 13, and multiple first upper reinforcing ribs 16 are provided. The upper end of the first upright post 13 is fixedly connected to the top connecting part 3, and the lower end of the first upright post 13 is fixedly connected to the end of the second body part 5. There is an angle between the width direction of the first upright post 13 and the width direction of the first connecting surface 14, and this angle is less than 180 degrees. One end in the width direction of the first connecting surface 14 is fixedly connected to one end in the width direction of the first upright post 13, and the other end in the width direction of the first connecting surface 14 is fixedly connected to the first flanging surface 15. The width directions of the first upright post 13 and the first connecting surface 14 are perpendicular to the Z direction. By setting an angle between the first upright post 13 and the first connecting surface 14, a step feature is formed on the first body part 4, which improves the force load on the first body part 4, changes the straight-through force transmission form of the original structure, makes the force structure of the product stronger, cancels the inner welding edge of the original "ji" - shaped structure, optimizes the over - designed structural performance here, changes it to a random design form, adds an extended - shape reinforcing rib design form during the lamp socket cycle, strengthens the positions that need to be reinforced in the original lamp socket, weakens the positions that do not require structural strength, effectively improves the structural performance of the front lamp frame assembly. After the structural optimization design of the product, the installation operation space of the front lamp is effectively increased, effectively solving the problem that the original structure has insufficient structural performance resulting in insufficient installation operation space for the front lamp and the inability to increase the operation space.

[0047] The setting of the first upper reinforcing rib 16 optimizes the lower structure of the front baffle of the radiator frame, improves the crash safety protection and collapse performance of the front of the vehicle head, changes the original structural design form of the reinforcing rib, adds a through - body random reinforcing rib structurally to avoid broken ribs in design. When a frontal collision occurs to the vehicle, the strength here is increased. Transverse force - enhancing ribs are added to the lower part of the part, and the rib depth is changed to 6 mm, which is twice the original rib depth. The strength of the lower edge of the part is significantly improved. Large gaps are added to the positions where the strength of the part is not required, reducing the weight of the single - part front lamp frame of the part.

[0048] In the embodiment of the present invention, as Figure 1 and Figure 5As shown, the fourth body part 7 includes a second column 17, a second connection surface 18 connected to the second column 17, and a second flanging surface 19 connected to the second connection surface 18. The second connection surface 18 is located between the second column 17 and the second flanging surface 19. Second upper stiffening ribs 20 are provided on the second column 17, and multiple second upper stiffening ribs 20 are provided. The upper end of the second column 17 is fixedly connected to the top connection part 3, and the lower end of the second column 17 is fixedly connected to the end of the third body part 6. There is an angle between the width direction of the second column 17 and the width direction of the second connection surface 18, and this angle is less than 180 degrees. One end in the width direction of the second connection surface 18 is fixedly connected to one end in the width direction of the second column 17, and the other end in the width direction of the second connection surface 18 is fixedly connected to the second flanging surface 19. The width directions of the second column 17 and the second connection surface 18 are perpendicular to the Z direction. By setting an angle between the second column 17 and the second connection surface 18, a step feature is formed on the second body part 5, improving the force-bearing load of the fourth body part 7, changing the straight-through force transmission form of the original structure, and making the force-bearing structure of the product stronger.

[0049] The provision of the second upper stiffening ribs 20 optimizes the structural strength of the radiator column, changes the original "U-shaped" stiffening beam design scheme to a single-sided deep flanging structure form of the part, and adds a step feature at the position of the side wall surface of the single-sided flanging, improving the single-sided force-bearing load of the part and changing the original straight-through force transmission form.

[0050] In this embodiment of the invention, by optimizing the original headlight frame product structure, the areas with insufficient structural strength are reinforced, while the areas with excessive structural strength are weakened. The original design of the lamp opening being separated vertically and horizontally is reinforced and connected, and the original disconnect between the left and right pillars is filled. This effectively improves the problem of insufficient structural strength around the lamp opening of the headlight frame. After optimization, the product structure around the lamp opening is a closed ring structure, which solves the problem of improving the overall structural strength performance of the headlight frame. The original design of the front side plate of the radiator frame is relatively weak with a shallow cross-section and insufficient structural strength. The original design is optimized to enhance the depth of the flanged sidewall in the negative Y direction of the headlight frame assembly, improving the load-bearing capacity under X-direction external forces applied in the direction of the vehicle's front, effectively improving the problem of insufficient frame strength in the front side plate of the original radiator frame. The design of the lower part of the front baffle of the radiator frame has been optimized to improve the crumple zone performance of the front end in a frontal collision. The original reinforcing rib design has been changed, and a continuous, flexible reinforcing rib has been added to prevent rib breakage. This increases strength in this area during a frontal collision. Lateral reinforcing ribs have been added to the lower part of the component, with the rib depth increased to 6mm (2 times the original depth), significantly improving the edge strength of the lower part. Large notches have been added in areas where strength is not critical to reduce the weight of the headlight frame component. The radiator pillar structure has also been optimized, changing the original "U"-shaped reinforcing beam design to a single-sided deep flange structure. The addition of stepped features to the wall surface enhances the load-bearing capacity on one side of the component, altering the original straight-through force transmission method and making the product's structural strength stronger. The original round hole on the top surface has been eliminated, increasing the strength of the top surface's structural strength. The original "U"-shaped structure's inner welded edge has been removed, addressing the issue of excessive performance at the inner welded lap joint surface of the "U"-shaped component, and replacing it with a more flexible design. Stepped reinforcing ribs have been added around the lamp opening to reinforce the weak points of the original lamp opening, while weakening other areas where structural strength is not required. This effectively solves the problem of insufficient structural strength in the headlight frame assembly. The optimized product structure design also effectively resolves the issue of insufficient installation and operation space for the headlights.

[0051] The headlight frame body and upper crossbeam section 2 are connected to the front frame assembly and wheel arch side beam assembly of the vehicle. In this embodiment of the invention, increasing the overall structural curvature of the headlight frame body and upper crossbeam section 2 can better transmit the front collision force to the front frame assembly and wheel arch side beam assembly, improving the problem of insufficient front collision performance. This effectively solves the problem of insufficient performance due to the small curvature change of the original structure, and the problem of overall structural collapse caused by front collision at this point. Optimizing the width of the original design section and adjusting it to be consistent helps to solve the difficulties in part forming, reduce the later part debugging cycle, shorten the development and design time, reduce the mounting point features on the top surface, and eliminate the two side wall features. The side-flipped edge avoids the notch, effectively solving the problem of cracking of parts at the notch when subjected to Z-direction stress in the original structure. The notch positions on the side wall of the optimized part structure have all been eliminated, improving its own structural strength. The length of the X-direction flipped edge of the front of the vehicle has been increased, improving the overall structural strength of the product in the Z-direction stress direction. This effectively solves the problem of insufficient structural strength of the original radiator upper crossbeam. The product structure simplifies the problem of individual part accuracy and welding accuracy. The overlapping position of the two ends of the part has been simplified and changed to a flat overlapping structure with a shortened overlapping length, which significantly improves the individual part accuracy at the overlapping interface of the two ends of the part, allowing for better matching and overlapping with the radiator upper crossbeam and the engine compartment side longitudinal beam.
