Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically to a front cover assembly for a vehicle. Background Technology

[0002] A vehicle hood typically consists of an outer hood panel and an inner hood panel. The inner hood panel also has an independent support section to provide stable support when the vehicle hood is opened.

[0003] With the development of the automotive industry, consumers have placed increasingly higher demands on vehicle appearance, safety, and cost control. In terms of appearance, to create a stylish and sporty look like a coupe, vehicle hoods are being designed to be increasingly low-slung. Due to this low-slung hood design, to avoid obstructing the headlights, the first vertical surface of the inner hood panel is far from the edge, resulting in insufficient cavity area between the outer and inner hood panels. This not only causes the hood's modal performance to fail to meet requirements but also makes it difficult to install the support structure. Utility Model Content

[0004] This application provides a front cover assembly for a vehicle that not only improves the modal performance of the front cover assembly but also integrates the function of a hand support rod, realizing multiple functions in one component. This improves the utilization rate of parts, reduces the number and cost of parts, and also reduces the assembly difficulty and assembly steps of the front cover assembly, thereby reducing the production cost of the front cover assembly and improving production efficiency.

[0010] In some embodiments, a portion of the first reinforcing plate and a portion of the second reinforcing plate are abutted against the inner front cover panel, and the first reinforcing plate and the second reinforcing plate are spaced apart from the outer front cover panel.

[0011] In some embodiments, the area of ​​the first reinforcing plate corresponding to the support portion is connected to the inner front cover plate via a first weld point, and the area of ​​the second reinforcing plate where the support portion is disposed is connected to the inner front cover plate via a second weld point, wherein the number of the second weld points is greater than the number of the first weld points.

[0012] In some embodiments, the area corresponding to the support portion of the first reinforcing plate is provided with a first weld point, and the area where the support portion is located of the second reinforcing plate is provided with two second weld points, which are respectively located on opposite sides of the support portion.

[0013] In some embodiments, one or more third welding points are provided near the edge of the first reinforcing plate, and the edge of the first reinforcing plate is connected to the inner front cover plate through the third welding points;

[0014] One or more fourth welding points are provided near the edge of the second reinforcing plate, and the edge of the second reinforcing plate is connected to the inner front cover plate through the fourth welding points.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.

[0030] In this application, unless otherwise expressly specified and limited, the terms "connected," "linked," "stacked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] This application provides a hood assembly for a vehicle, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0032] Reference Figure 1One embodiment of this application provides a hood assembly for a vehicle, including: an inner hood panel 2, an outer hood panel 3, and a reinforcing structure 1. The reinforcing structure 1 can be disposed between the inner hood panel 2 and the outer hood panel 3. The reinforcing structure 1 not only enhances the structural strength of the inner hood panel 2, but also optimizes the stress distribution of the hood assembly, thereby improving the modal performance of the hood assembly. Modal performance refers to the structural response characteristics of the hood assembly at vibration frequencies. In some embodiments, the reinforcing structure 1 can also be disposed on the side of the inner hood panel 2 facing away from the outer hood panel 3. The distance L between the first vertical surface 24 of the inner hood panel 2 and the headlight module 8 satisfies: L≥10mm. For example, the distance L between the first vertical surface 24 of the inner hood panel 2 and the headlight module 8 can be any value among 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, etc., or any value between two of them. This distance setting is to meet the requirements of the low-profile design of the front cover assembly, while avoiding the headlight module 8, ensuring that there is enough space between the inner panel 2 of the front cover and the headlight module 8 to avoid mutual interference, and also to improve the commonality rate of the headlight module 8.

[0033] Specifically, the inner hood panel 2 and the outer hood panel 3 are positioned opposite each other, with the inner hood panel 2 facing the vehicle engine and the outer hood panel 3 facing away from the vehicle engine. Please refer to both. Figure 2 When the hood assembly is installed in the vehicle, from the driver's cab perspective, the inner hood panel 2 has a left side 21 and a right side 22 in the vehicle width direction, and the end of the inner hood panel 2 away from the driver's cab in the vehicle length direction is the front end 23 of the inner hood panel 2.

[0034] Reference Figure 1 and Figure 2 The reinforcing structure 1 is disposed on the side of the inner front cover 2 facing the outer front cover 3, and the reinforcing structure 1 is preferably fixedly connected to the inner front cover 2. The reinforcing structure 1 can be made of metal, such as aluminum alloy or stainless steel.

[0035] Please refer to the following: Figure 3 and Figure 4 The reinforcing structure 1 may include a first reinforcing plate 11 and a second reinforcing plate 12. Both the first reinforcing plate 11 and the second reinforcing plate 12 are disposed close to the front end 23 of the inner front cover 2, and the first reinforcing plate 11 and the second reinforcing plate 12 are disposed close to the opposite sides of the inner front cover 2. This not only strengthens the structural strength of the front end 23 of the inner front cover 2, but also improves the stress distribution of the front end 23 of the inner front cover 2, thereby improving the modal performance of the front cover assembly.

[0036] Reference Figure 4The second reinforcing plate 12 is provided with a support portion 121 for supporting a hand support rod (not shown). The inner front cover plate 2 has a mounting hole 25 at a position corresponding to the support portion 121, through which the hand support rod passes. When the front cover assembly is open, one end of the hand support rod can pass through the mounting hole 25 and connect to the support portion 121. Compared to having the support portion 121 separately, integrating the hand support rod into the second reinforcing plate 12 in this application not only reduces the space occupied by the support portion 121, thus accommodating the increasingly smaller cavity design between the outer front cover plate 3 and the inner front cover plate 2, but also reduces the number of parts and assembly steps, thereby lowering the production cost of the front cover assembly and improving production efficiency.

[0037] Reference Figure 4 The support portion 121 is preferably located near the center of the second reinforcing plate 12. This ensures that the second reinforcing plate 12 has sufficient structural strength. The support portion 121 has a through-hole structure and is used to engage the hand support rod. This through-hole structure of the support portion 121 facilitates the installation and removal of the hand support rod, while providing stable support force. In this embodiment, referring to... Figure 3 The first reinforcing plate 11 can also be provided with the same through hole structure as the second reinforcing plate 12, except that the first reinforcing plate 11 is not connected to the hand support rod.

[0038] As a preferred method, refer to Figure 2 The first reinforcing plate 11 and the second reinforcing plate 12 are respectively disposed near the opposite left side 21 and right side 22 of the inner front cover panel 2. More preferably, the structures of the first reinforcing plate 11 and the second reinforcing plate 12 can be the same or similar. In this embodiment, the structures of the first reinforcing plate 11 and the second reinforcing plate 12 are symmetrically arranged, and the first reinforcing plate 11 and the second reinforcing plate 12 are symmetrically disposed on the left side 21 and right side 22 of the inner front cover panel 2, respectively. In this way, the first reinforcing plate 11 and the second reinforcing plate 12 are symmetrically distributed along the center line of the inner front cover panel 2, which can ensure that the structural strength of the left and right sides of the inner front cover panel 2 is the same or approximately the same, thereby improving the modal performance of the front cover assembly. For example, in the prior art, the free mode of the front cover assembly is 26Hz. By setting the first reinforcing plate 11 and the second reinforcing plate 12, this application improves the free mode of the front cover assembly to 28Hz, which is 7.7% higher than the 26Hz of the prior art.

[0039] In this application, by placing both the first reinforcing plate 11 and the second reinforcing plate 12 close to the front end 23 of the inner front cover panel 2, and placing the first reinforcing plate 11 and the second reinforcing plate 12 close to opposite sides of the inner front cover panel 2, the modal performance of the front cover assembly can be improved, effectively increasing the vibration frequency of the front cover assembly, enhancing the structural rigidity and stability of the front cover assembly, reducing problems such as loosening of parts and abnormal noises caused by vibration during driving, and improving the overall performance and reliability of the vehicle. The second reinforcing plate 12 is provided with a support part 121, which supports the hand support rod. That is, the second reinforcing plate 12 integrates the function of the hand support rod, realizing multiple functions in one component, improving the utilization rate of parts, reducing the number of parts and cost, and also reducing the assembly difficulty and assembly steps of the front cover assembly, thereby reducing the production cost of the front cover assembly and improving production efficiency.

[0040] In one specific implementation, refer to Figure 1 and Figure 2 A portion of the first reinforcing plate 11 and a portion of the second reinforcing plate 12 are abutted against the inner front cover panel 2. This improves the stability of the connection between the first and second reinforcing plates 11 and the inner front cover panel 2, thereby ensuring the structural strength of the inner front cover panel 2. The first and second reinforcing plates 11 and 12 are spaced apart from the outer front cover panel 3. This avoids direct contact between the first and second reinforcing plates 11 and 12 and the outer front cover panel 3. For example, when a pedestrian's head collides with the front cover assembly, the first and second reinforcing plates 11 and 12 will not affect the deformation of the outer front cover panel 3, ensuring that the outer front cover panel 3 can deform to absorb the impact force on the pedestrian, thereby reducing injury to the pedestrian's head.

[0041] The first reinforcing plate 11 and the support portion 121 can be connected by laser welding or other methods, and the second reinforcing plate 12 and the support portion 121 can also be connected by laser welding or other methods. (Refer to...) Figure 3 and Figure 4The area corresponding to the support portion 121 of the first reinforcing plate 11 is connected to the inner front cover panel 2 via a first weld point 4. The area of ​​the support portion 121 on the second reinforcing plate 12 is connected to the inner front cover panel 2 via a second weld point 5. The number of second weld points 5 is greater than the number of first weld points 4, and the first weld points 4 and second weld points 5 are asymmetrically distributed. The first reinforcing plate 11 does not require a support for the hand strut. While ensuring the connection strength between the first reinforcing plate 11 and the inner front cover panel 2, the number of first weld points 4 is reduced. This not only reduces costs but also decreases the number of exposed first weld points 4, thereby improving the overall appearance of the front cover assembly. The greater number of second weld points 5 increases the connection strength between the second reinforcing plate 12 and the inner front cover panel 2, thus meeting the strength requirements for the second reinforcing plate 12 to support the hand strut and preventing the second reinforcing plate 12 from separating from the inner front cover panel 2 under stress.

[0042] As an example, refer to Figure 3 and Figure 4 The first reinforcing plate 11 has a first welding point 4 in the area corresponding to the support part 121, and the second reinforcing plate 12 has two second welding points 5 in the area where the support part 121 is located. The two second welding points 5 are respectively located on opposite sides of the support part 121, that is, the two second welding points 5 are evenly distributed around the support part 121. The connection force between the second reinforcing plate 12 and the inner front cover 2 is more evenly distributed, thereby preventing the second reinforcing plate 12 from separating from the inner front cover 2 due to force.

[0043] Reference Figure 3 One or more third weld points 6 can be provided near the edge of the first reinforcing plate 11. The edge of the first reinforcing plate 11 is connected to the inner front cover plate 2 through the third weld points 6. The third weld points 6 can further improve the connection strength between the first reinforcing plate 11 and the inner front cover plate 2. Furthermore, the third weld points 6 are located at the edge of the first reinforcing plate 11, which can improve the modal performance of the front cover assembly. In this embodiment, there are four third weld points 6. The third weld points 6 can be formed in the same way as the first weld points 4, or they can be formed simultaneously with the first weld points 4.

[0044] Reference Figure 4 One or more fourth weld points 7 are provided near the edge of the second reinforcing plate 12. The edge of the second reinforcing plate 12 is connected to the inner front cover plate 2 through the fourth weld points 7. The fourth weld points 7 can further improve the connection strength between the second reinforcing plate 12 and the inner front cover plate 2. Furthermore, the fourth weld points 7 are located at the edge of the second reinforcing plate 12, which can improve the modal performance of the front cover assembly. In this embodiment, there are four fourth weld points 7. The fourth weld points 7 can be formed in the same way as the second weld points 5, or they can be formed simultaneously with the second weld points 5.

[0045] Reference Figure 1 , Figure 3 and Figure 4 The welding surface 13 of the reinforcing structure 1 is abutted against the inner front cover panel 2, that is, the welding surface 13 of the first reinforcing plate 11 and the welding surface 13 of the second reinforcing plate 12 are both abutted against the inner front cover panel 2. In other words, the first reinforcing plate 11 has the corresponding positions of the first welding point 4 and the third welding point 6 abutted against the inner front cover panel 2, and the second reinforcing plate 12 has the corresponding positions of the second welding point 5 and the fourth welding point 7 abutted against the inner front cover panel 2. This can improve the reliability of the welding between the first reinforcing plate 11 and the second reinforcing plate 12 and the inner front cover panel 2, thereby improving the connection strength between the first reinforcing plate 11 and the second reinforcing plate 12 and the inner front cover panel 2.

[0046] As a preferred method, refer to Figure 3 and Figure 4 The first reinforcing plate 11 may be provided with a first hollow portion 111, and the second reinforcing plate 12 may be provided with a second hollow portion 122. The first hollow portion 111 and the second hollow portion 122 can reduce the weight of the first reinforcing plate 11 and the second reinforcing plate 12, reduce material costs, and at the same time, do not affect the strength and modal performance improvement effect of the first reinforcing plate 11 and the second reinforcing plate 12.

[0047] Reference Figure 3 and Figure 4 The first reinforcing plate 11 may also be provided with a first reinforcing part 112, and the second reinforcing plate 12 may also be provided with a second reinforcing part 123. The first reinforcing plate 11 and the second reinforcing part 123 can enhance the strength of the first reinforcing plate 11 and the second reinforcing plate 12, further improving the modal performance of the front cover assembly. Furthermore, the first reinforcing part 112 and the second reinforcing part 123 protrude away from the inner front cover plate 2, meaning that the first reinforcing part 112 and the second reinforcing part 123 can have a certain distance from the inner front cover plate 2. This eliminates the need for the third welding point 6 and the fourth welding point 7 at the corresponding positions of the first reinforcing part 112 and the second reinforcing part 123, thus further reducing costs and decreasing the number of exposed third welding points 6 and fourth welding points 7, thereby improving the overall appearance of the front cover assembly.

[0048] Reference Figure 3 and Figure 4The first reinforcing plate 11 may also be provided with a first error-proof part 113, and the second reinforcing plate 12 may also be provided with a second error-proof part 124. The first error-proof part 113 and the second error-proof part 124 can prevent installation errors and improve production efficiency. As an example, the first error-proof part 113 may include a round hole and an elliptical hole, with the round hole located on the side of the first reinforcing plate 11 closer to the second reinforcing plate 12 and the elliptical hole located on the side of the first reinforcing plate 11 away from the second reinforcing plate 12. The second error-proof part 124 may also include a round hole and an elliptical hole, with the round hole located on the side of the second reinforcing plate 12 closer to the first reinforcing plate 11 and the elliptical hole located on the side of the second reinforcing plate 12 away from the first reinforcing plate 11. In some embodiments, the first error-proof part 113 and the second error-proof part 124 may also take other shapes.

[0049] Reference Figure 3 and Figure 4 The first reinforcing plate 11 and the second reinforcing plate 12 are both integrally formed structures, which can be achieved by stamping, die casting or laser cutting processes. This not only ensures the strength and precision of the first reinforcing plate 11 and the second reinforcing plate 12, but also simplifies the production process, thereby reducing manufacturing costs and improving production efficiency.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application.
