[0025] Please also read Figures 1 to 4 The hood inner panel structure, hood assembly and vehicle provided by the utility model are now described. The hood inner panel structure includes an inner panel body 1 and a reinforcing plate 2. The inner panel body 1 has a hollow cavity 11. The reinforcing plate 2 includes two side diagonal braces 3 symmetrically arranged on both sides of the center axis of the vehicle body. The rear ends of the two side diagonal braces 3 are respectively connected to the rear side edges of the hollow cavity 11, and the front ends of the two side diagonal braces 3 are respectively connected to the front side edges of the hollow cavity 11, and the front ends of the two side diagonal braces 3 are inclined and extended to the adjacent sides until they are connected.

[0026] Compared with the prior art, the hood inner panel structure provided in the present embodiment can effectively improve the structural strength of the entire hood inner panel by arranging a reinforcing plate 2 in the hollow cavity 11 of the inner panel body 1. The two side diagonal braces 3 can cooperate with the rear of the hollow cavity 11 to form a triangular reinforcement structure, which improves the bending and torsional rigidity and structural strength of the hood inner panel, helps to improve the stability of the hood assembly during the opening and closing process, and avoids deformation of the hood during production and use. The above-mentioned structure, based on the use of the hollow cavity 11 for structural weight reduction, can also use the free area of ​​the hollow cavity 11 during stamping to arrange other small-sized components, which is convenient for simultaneous stamping and forming of multiple components, helps to reduce the number of molds, improve component manufacturing efficiency, and help to reduce material costs.

[0027] In this embodiment, on the basis of satisfying the structural strength of the hood inner panel itself, the lightweight design of the structure should be considered as much as possible. The above structure sets a hollow cavity 11 on the inner panel body 1, and sets a reinforcing plate 2 in the hollow cavity 11. The reinforcing plate 2 can not only strengthen the structure of the entire hood inner panel, but also use the area outside the reinforcing plate 2 to arrange other small-sized components during the component stamping process. Multiple components can be developed and manufactured through the same mold, which is convenient for reducing the development cost of the mold.

[0028] It should be noted that the hollow cavity 11 has a circular closed side edge. For the convenience of description, the side edge of the hollow cavity 11 close to the front of the vehicle is defined as the front side edge, and the side edge of the hollow cavity 11 close to the rear of the vehicle is defined as the rear side edge.

[0029] On this basis, the above-mentioned characteristic reinforcement plate 2 adopts Figures 1 to 3 See the structure shown. Figures 1 to 3 The reinforcing plate 2 also includes at least one middle support 4, the front end of the middle support 4 is connected to the front end of the side diagonal support 3, the rear end of the middle support 4 is connected to the rear side edge of the hollow cavity 11, and the middle support 4 is located between the two side diagonal supports 3.

[0030] The middle support 4 is connected between the front edge and the rear edge of the hollow cavity 11. On the basis that the front ends of the two side diagonal supports 3 are connected as one, the front end of the middle support 4 is connected as one with the front ends of the two side diagonal supports 3, which can assist the side diagonal supports 3 in structural support.

[0031] At the same time, the middle support 4 is located between the two side diagonal supports 3, and cooperates with the side diagonal supports 3 to form a divergent shape from front to back. One or more middle supports 4 can be provided. If one is provided, it is provided along the central axis of the vehicle body. If multiple are provided, one is provided along the central axis of the vehicle body, and the other middle supports 4 are symmetrically arranged on both sides of the above-mentioned middle support 4, so as to achieve effective coverage in the width direction of the vehicle body, and effectively improve the structural strength of the hollow cavity 11.

[0032] In some embodiments, the above-mentioned feature reinforcement plate 2 can be used as follows Figures 1 to 3 See the structure shown. Figures 1 to 3 The reinforcing plate 2 further includes a transverse brace 5, the two ends of which are connected to the two side diagonal braces 3 one by one, and the transverse brace 5 is cross-arranged with the middle brace 4 and formed in one piece. By providing the transverse brace 5 extending in the width direction of the vehicle body, the middle brace 4 and the side diagonal brace 3 can be connected to each other to form a unified whole, further improving the bending and torsional rigidity and structural strength of the reinforcing plate 2, and reinforcing the plate 2 to strengthen the structure of the hood inner plate.

[0033] In this embodiment, by arranging the transverse support 5 and the middle support 4 between the two side diagonal supports 3, two triangular cavities located in front of the transverse support 5 can be formed. The two triangular cavities are located on both sides of the middle support 4, respectively, forming a right-angled triangle structure.

[0034] On this basis, a reinforcing brace 34 extending backward is also provided on the inner side of the side diagonal brace 3, and the reinforcing brace 34 can effectively support the rear portion of the side diagonal brace 3 and the rear side edge of the hollow cavity 11. At the same time, the reinforcing brace 34 can cooperate with the transverse brace 5, the middle brace 4 and the rear side edge of the hollow cavity 11 to enclose a rectangular cavity. There are two rectangular cavities, which are symmetrically distributed on both sides of the middle brace 4.

[0035] At the same time, an irregular cavity is formed on the outer side of each of the two side braces 3, and six vertically penetrating cavity structures can be formed. When the inner panel body 1 is stamped and formed by a mold, a structure of small-sized components can be arranged in the above one or more cavities, for example, a structure capable of forming components such as a fender reinforcement plate 9 or a hood support plate 8 can be arranged, so as to realize the synchronous forming of multiple components.

[0036] Specifically, the outer area of ​​the side diagonal support 3 can be used to arrange the structure for forming the fender reinforcement plate 9, and the rectangular cavity on the rear side of the transverse support 5 can be used to arrange the structure for forming the hood support plate 8. Other cavities can be used to arrange structures capable of forming other small components according to actual usage.

[0037] In summary, when the mold is used for stamping, while the mold is used to form the inner panel body 1, components such as the fender reinforcement plate 9 or the hood support plate 8 can also be formed, achieving a one-mold-multiple-piece forming effect, effectively improving the mold forming efficiency, reducing the mold development cost, and also reducing the component production cost.

[0038] In some possible implementations, the characteristic side brace 3 is as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3 The side diagonal brace 3 is provided with a first reinforcing strip 61 extending along the direction of the side diagonal brace 3, the middle brace 4 is provided with a second reinforcing strip 62 extending along the direction of the middle brace 4, and the transverse brace 5 is provided with a third reinforcing strip 63 extending along the direction of the transverse brace 5. The first reinforcing strip 61, the second reinforcing strip 62 and the third reinforcing strip 63 are crossed or connected in pairs.

[0039] In this embodiment, without increasing the thickness of the side diagonal brace 3, the structural strength of the side diagonal brace 3 is increased by providing a first reinforcement strip 61 on the side diagonal brace 3. Similarly, a second reinforcement strip 62 is provided on the middle brace 4, and a third reinforcement strip 63 is provided on the transverse brace 5, which can play the same structural reinforcement role and facilitate the lightweight design of the structure.

[0040] Specifically, taking the side brace 3 as an example, a first reinforcing strip 61 protruding upward can be provided on the top surface of the side brace 3, or a first reinforcing strip 61 protruding downward can be provided on the bottom surface of the side brace 3. The first reinforcing strip 61 is integrally formed on the side brace 3, and can achieve a structural reinforcement effect on the side brace 3. The second reinforcing strip 62 and the third reinforcing strip 63 are arranged in the same manner, which will not be described in detail here.

[0041] In some embodiments, see Figures 1 to 3 A plurality of first weight-reducing holes 64 are respectively provided on the first reinforcement strip 61 , the second reinforcement strip 62 or the third reinforcement strip 63 .

[0042] In this embodiment, by providing first weight-reducing holes 64 on the side diagonal brace 3, the middle brace 4 and the transverse brace 5, the structural weight reduction of the above components is achieved, which helps to reduce material consumption and reduce component manufacturing costs.

[0043] Specifically, taking the side brace 3 as an example, the first weight-reducing hole 64 is arranged on the first reinforcing strip 61, and the first weight-reducing hole 64 can also be arranged on the side brace 3 to enhance the weight-reducing effect of the entire side brace 3. The arrangement position of the first weight-reducing hole 64 can be selected according to the width relationship between the first reinforcing strip 61 and the side brace 3 to achieve a good weight-reducing effect. The second weight-reducing hole 73 is arranged in the same manner on the second reinforcing strip 62 and the third reinforcing strip 63, which will not be described in detail here.

[0044] In some possible implementations, the above-mentioned characteristic reinforcement plate 2 is adopted as follows Figures 1 to 3 See the structure shown. Figures 1 to 3 Connecting parts 31 are respectively provided on both sides of the reinforcing plate 2, and the connecting parts 31 are connected to the front side edges of the hollow cavity 11. Reinforcing ears 32 are also respectively provided on both sides of the reinforcing plate 2, and reinforcing ridges 33 are provided on the reinforcing ears 32.

[0045] In this embodiment, an acute angle is formed between the outer edge of the reinforcing plate 2 and the front edge of the hollow cavity 11. The structural strength of this position is relatively low, and the structure can be reinforced by the connecting portion 31. By providing the connecting portions 31 on both sides of the front end of the reinforcing plate 2, the position where the reinforcing plate 2 and the front edge of the hollow cavity 11 are connected can be structurally reinforced, thereby increasing the connection area between the front end of the reinforcing plate 2 and the front edge of the hollow cavity 11, and ensuring the structural reinforcement performance of the reinforcing plate 2.

[0046] Specifically, the connecting portion 31 is a fan-shaped structure, which is connected to the outer side of the front end of the side diagonal brace 3. The side of the connecting portion 31 away from the side diagonal brace 3 is an arc-shaped edge. The setting of the arc-shaped edge can achieve structural avoidance with other components, and at the same time form an effect of supporting between the outer edge of the side diagonal brace 3 and the front edge of the hollow cavity 11, thereby ensuring a reliable connection between the reinforcing plate 2 and the inner plate body 1.

[0047] On the basis of the above structure, the two side edges of the reinforcing plate 2 are further provided with reinforcing ears 32, which are integrally formed on the opposite sides of the two side braces 3, and the extending direction of the reinforcing ears 32 is consistent with the extending direction of the side braces 3. A plurality of reinforcing ears 32 are provided at intervals in the extending direction of the same side brace 3, so that the structure of different positions of the side brace 3 can be reinforced.

[0048] Furthermore, a reinforcing ridge 33 is provided on the reinforcing ear 32 . The reinforcing ridge 33 can be provided to protrude downward or upward, so as to further enhance the structural strength of the reinforcing ear 32 .

[0049] In some possible implementations, the above-mentioned characteristic inner plate body 1 is adopted as follows Figures 1 to 3 See the structure shown. Figures 1 to 3 A front transition strip 71 and a rear transition strip 72 are provided on the inner plate body 1. The front transition strip 71 is connected to the front side edge of the hollow cavity 11, and extends backward and upward to be connected to the front side edge of the reinforcing plate 2. The rear transition strip 72 is connected to the rear side edge of the hollow cavity 11, and extends backward and front upward to be connected to the rear side edge of the reinforcing plate 2. Second weight-reducing holes 73 are respectively provided on the front transition strip 71 and the rear transition strip 72.

[0050] In this embodiment, a front transition strip 71 and a rear transition strip 72 are provided on the inner plate body 1. The front transition strip 71 is connected to the front side edge of the hollow cavity 11, and the rear transition strip 72 is connected to the rear side edge of the hollow cavity 11. The front transition strip 71 can achieve a reliable connection with the front end of the reinforcing plate 2, and the rear transition strip 72 can achieve a reliable connection with the rear end of the reinforcing plate 2. The connecting portion 31 is located between the rear side edge of the front transition strip 71 and the outer side edge of the side brace 3, thereby improving the reliability of the structural connection.

[0051] Furthermore, the front transition strip 71 is bent and protruded upward and rearward, while the rear transition strip 72 is gradually bent and protruded upward and forward. The above structure can make the entire reinforcement plate 2 protrude upward from the plate surface of the inner plate body 1, forming an overall arching effect, which is convenient for improving the structural strength of the entire hood inner plate structure, ensuring effective support for the hood outer plate, and making the entire hood assembly have good structural stability.

[0052] By providing the second weight-reducing holes 73 on the front transition bar 71 and the rear transition bar 72, the structural weight of the front transition bar 71 and the rear transition bar 72 can be effectively reduced, thereby facilitating a good lightweight design and achieving the effect of saving materials.

[0053] In one possible implementation, see Figure 4 The hood inner panel structure also includes a hood support plate 8 connected to the top surface of the inner panel body 1. The hood support plate 8 is located at the rear side of the hollow cavity 11. Both ends of the hood support plate 8 respectively have support arms 81 extending outward and upward. The support arms 81 have a support surface that can be supported under the hood outer panel.

[0054] In this embodiment, when the inner panel body 1 is being formed, the hood support plate 8 can be formed simultaneously. The hood support plate 8 is used to be installed on the upper rear part of the inner panel body 1, and can form a supporting effect on the hood outer panel with the help of the supporting surfaces on the two support arms 81, thereby ensuring a reliable connection between the inner panel body 1 and the hood outer panel.

[0055] Specifically, the upper ends of the two support arms 81 extend horizontally to opposite sides respectively, forming a support surface that can be connected to the bottom surface of the hood outer panel, so as to increase the supporting area of ​​the hood outer panel and improve the reliability of the support.

[0056] Based on the same inventive concept, the embodiment of the present application also provides a hood assembly, which includes a hood inner panel structure. The hood assembly adopts the form of combining the inner panel body 1 and the reinforcing plate 2, which not only ensures the structural strength of the hood inner panel, but also facilitates the use of the free space in the hollow cavity 11. When the hood inner panel is formed by using a mold, other components can be formed simultaneously to achieve the effect of one mold for multiple parts, which helps to reduce the number of molds, improve the efficiency of component manufacturing, and help reduce material costs.

[0057] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, the vehicle including a hood assembly, and the vehicle has the above-mentioned effects, which will not be elaborated here.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
