Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and more particularly to an engine hood and vehicle. Background Technology

[0002] The hood is a body component at the front of a vehicle. It not only serves as a cover for the engine compartment, but also, together with the front exterior components, constitutes the front shape of the vehicle. It is one of the external parts that users can clearly perceive and touch.

[0003] For hardcore off-road vehicles, in addition to meeting the requirements of pedestrian protection and vehicle aesthetics, the engine hood also needs to have a certain load-bearing capacity so that users can stand or sit on the engine hood to take pictures or enjoy the scenery. Therefore, how to improve the load-bearing capacity of the engine hood is an issue that needs to be considered. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides an engine hood and a vehicle, which improves the rigidity and load-bearing capacity of the engine hood by setting the outer panel, the inner panel and the supporting stiffeners, thereby meeting the needs of users.

[0005] The first aspect of this application provides an engine hood, comprising:

[0006] The inner panel of the hood has reinforcing ribs that have a hollow structure.

[0007] The outer panel of the machine cover is connected to the inner panel of the machine cover;

[0008] A supporting rib is disposed between the inner panel and the outer panel of the machine cover. The supporting rib is disposed corresponding to the reinforcing rib and is connected to the inner panel and the outer panel of the machine cover.

[0009] The engine hood provided in this application embodiment features supporting ribs positioned between the inner and outer panels of the hood. These supporting ribs correspond to reinforcing ribs and are connected to both the inner and outer panels. By using these supporting ribs to compensate for the strength of the reinforcing ribs in the inner panel, which have a hollow structure, the overall rigidity and strength of the engine hood are enhanced, thereby improving its load-bearing capacity and meeting the needs of users standing or sitting on the engine hood.

[0010] Furthermore, the support ribs ensure that the inner hood panel still meets the requirements for lightweight design, thus enhancing the load-bearing capacity of the engine hood while also taking into account the economy of the inner hood panel.

[0011] In some embodiments, the supporting rib includes a rib body and a plurality of collapsible supporting legs, the rib body being disposed corresponding to the reinforcing rib, and the supporting legs being connected to the inner panel of the machine hood;

[0012] When the engine hood is subjected to force at its front end in the front-rear direction of the inner panel of the hood, the support leg collapses to absorb energy.

[0013] The aforementioned stiffener is connected to the inner panel of the hood via support legs, which provides support and increases the load-bearing capacity of the engine hood. Furthermore, when the front end of the engine hood is subjected to force, i.e., in the event of a collision, the support legs can absorb energy through collapse, thereby reducing injury to pedestrians.

[0014] In some embodiments, the main body of the rib plate includes a first rib and a plurality of second ribs. There are two first ribs. The first ribs extend along the left-right direction of the inner panel of the machine cover, and the two ribs are spaced apart in the front-back direction of the inner panel of the machine cover. The second ribs are disposed between the two first ribs, and the plurality of second ribs are spaced apart in the left-right direction of the inner panel of the machine cover.

[0015] The main body of the rib plate is reinforced by setting a first rib and multiple second ribs. The first rib extends along the left and right direction of the inner panel of the engine hood, and the second ribs extend along the front and rear direction of the inner panel of the engine hood. This provides reinforcement in the front and rear and left and right directions of the inner panel of the engine hood, thereby improving the load-bearing capacity of the engine hood.

[0016] In some embodiments, the stiffening plate body further includes a third stiffener and a fourth stiffener, at least one of the third stiffeners is disposed between two adjacent second stiffeners, and multiple fourth stiffeners are provided, which are disposed between two adjacent third stiffeners or between the third stiffeners and the first stiffeners.

[0017] The main body of the stiffening plate is constructed by setting a third and a fourth stiffening rib. The first and second stiffening ribs constitute the main structure of the stiffening plate, while the third and fourth stiffening ribs serve as branch structures of the stiffening plate. This enhances the structural strength of the supporting stiffening plate, creates more force transmission channels, and reduces the risk of local stress concentration in the main body of the stiffening plate.

[0018] In some embodiments, the reinforcing rib includes a first rib and a second rib located on both sides of the first rib in the left-right direction of the inner panel of the hood, wherein the area of ​​the hollowed-out area of ​​the first rib is larger than the area of ​​the hollowed-out area of ​​the second rib.

[0019] The first rib is located between the two second ribs, and the area of ​​the hollowed-out area of ​​the first rib is larger than that of the hollowed-out area of ​​the second rib. This allows the area where the first rib is located to achieve lightweighting while ensuring structural rigidity. The second rib is close to the boundary of the inner panel of the hood, which makes the bonding strength between the reinforcing rib and the part of the inner panel of the hood in the outer peripheral area higher, so that the inner panel of the hood as a whole has greater rigidity.

[0020] In some embodiments, the first rib portion includes an outer ring rib, an inner ring rib located inside the outer ring rib, and a plurality of connecting ribs located between the outer ring rib and the inner ring rib, with a hollow hole formed between two adjacent connecting ribs.

[0021] By designing outer ring ribs, inner ring ribs, and multiple connecting ribs, the first rib section improves the structural rigidity of the inner panel of the hood in this area while ensuring lightweight design.

[0022] In some embodiments, the second rib includes a main rib plate and a secondary rib plate connected to each other. The main rib plate extends along the left-right direction of the inner panel of the machine cover, and the main rib plate has a plurality of secondary rib plates on both sides of the inner panel of the machine cover in the front-back direction. The secondary rib plates extend along the front-back direction of the inner panel of the machine cover.

[0023] The two main stiffening plates of the second stiffening section and the two connecting stiffening plates of the first stiffening section are located on the same straight line extending in the left-right direction along the inner plate of the hood.

[0024] The aforementioned second rib is composed of a main rib plate and multiple secondary rib plates. Moreover, the two connecting ribs of the main rib plate and the first rib are located on the same straight line extending in the left and right direction along the inner panel of the machine cover. This forms a "barbell" structural design, in which the two second ribs act as "barbell plates" and the two connecting ribs of the first rib act as "barbell bars". This allows the first rib and the second rib to be connected, making the inner panel of the machine cover a high-rigidity whole.

[0025] In addition, the two main stiffening plates and the two connecting stiffeners can be regarded as the main stiffening ribs of the stiffening rib body, while the outer ring stiffener, inner ring stiffener, secondary stiffening plate and the remaining connecting stiffeners can be regarded as the branch stiffening ribs of the stiffening rib. This can make up for the problem of the large blank area on both sides of the main stiffening rib, thereby forming a strengthening effect on the inner plate of the machine cover in all directions, and also forming multiple force transmission channels to disperse and reduce the risk of local stress concentration in the inner plate of the machine cover.

[0026] In some embodiments, the first rib and the two second ribs are integrally formed.

[0027] By integrally molding the first and second ribs, the reinforcing ribs achieve good overall integrity and high structural strength.

[0028] In some embodiments, the outer panel of the hood is a sheet metal part, and the outer panel of the hood has a decorative part formed by stamping;

[0029] And / or, the outer panel of the hood is provided with a mounting area for mounting decorative parts.

[0030] By stamping the decorative parts onto the outer panel of the hood, not only are the number of parts reduced and installation steps eliminated, but the decorative parts are also stronger and less prone to damage and aging compared to plastic. Furthermore, the installation area on the outer panel allows users seeking personalized decorations to easily install them.

[0031] A second aspect of this application provides a vehicle including an engine hood as described in any of the preceding claims.

[0032] The vehicle has the technical effects of the aforementioned engine hood, which will not be elaborated further here. Attached Figure Description

[0045] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0046] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0047] The hood is a front-end component of a vehicle, serving not only as a cover for the engine but also contributing to the overall front styling of the vehicle along with other exterior parts. It is one of the most visible and tangible external components for users. For rugged off-road vehicles, in addition to meeting pedestrian protection and aesthetic requirements, the hood also needs to have sufficient load-bearing capacity to allow users to stand or sit on it for taking photos or enjoying the scenery. Therefore, improving the load-bearing capacity of the hood is a crucial consideration.

[0048] Based on this, this application provides an engine hood and a vehicle, which improves the structural strength of the engine hood at the location where the reinforcing ribs of the inner panel of the engine hood are arranged in a hollow structure by setting supporting ribs between the inner panel and the outer panel of the engine hood, thereby improving the load-bearing capacity of the engine hood and meeting the needs of users.

[0049] Furthermore, the inclusion of supporting ribs does not affect the design of the inner hood panel. The inner hood panel can be reinforced through a perforated structure, achieving a balance between impact resistance and pedestrian protection. In other words, the inclusion of supporting ribs enhances the load-bearing capacity of the engine hood while also ensuring its economic efficiency.

[0050] Reference Figures 1 to 6 Some embodiments of this application provide an engine hood, including an inner hood panel 1, an outer hood panel 2, and a support rib 3.

[0051] The inner panel 1 of the hood has a reinforcing rib 11 with a hollow structure.

[0052] The reinforcing ribs 11 of the inner panel 1 of the hood are hollow structures. This not only enables the weight reduction design of the inner panel 1 of the hood, but also allows the reinforcing ribs 11 to compensate for the strength loss of the inner panel 1 of the hood, thereby achieving a balance between the pressure resistance and impact resistance performance and the pedestrian protection performance of the inner panel 1 of the hood.

[0053] It should be noted that the aforementioned inner panel 1 of the hood can be divided into two regions: a central region 1a and an outer peripheral region 1b surrounding the central region 1a. The central region 1a is provided with the aforementioned reinforcing ribs 11. That is to say, the structure of the central region 1a of the inner panel 1 is a hollow structure, while the structure of the outer peripheral region 1b is not a hollow structure. In this way, the lightweight design of the inner panel 1 is achieved while ensuring the structural strength of the outer periphery of the inner panel 1. The central region 1a of the inner panel 1 can be understood as the exact center of the inner panel 1, symmetrical about the central axis of the inner panel 1. Alternatively, it can be understood as slightly deviated from the exact center, for example, relatively closer to the front or rear side of the inner panel 1 in the front-rear direction.

[0054] Reference Figure 3 In the diagram, the dotted line 'c' represents the central axis of the inner hood panel 1. The central axis of the inner hood panel 1 extends along its front-to-back direction and roughly coincides with the vehicle's central axis. In other words, the inner hood panel 1 has a roughly symmetrical structure, and its left-right axis of symmetry is its central axis. Therefore, the reinforcing rib 11 is also symmetrical about the central axis of the inner hood panel 1.

[0055] It should be noted that, referring to Figure 3 As shown in the diagram, the double-headed arrow X indicates the front-to-back direction of the inner hood panel 1, which is also the front-to-back direction of the vehicle. The double-headed arrow Y indicates the left-to-right direction of the inner hood panel 1, which is also the left-to-right direction of the vehicle.

[0056] Reference Figure 1 and Figure 2 The outer panel 2 of the hood is connected to the inner panel 1 of the hood. The supporting rib 3 is disposed between the inner panel 1 and the outer panel 2 of the hood. The supporting rib 3 is disposed corresponding to the reinforcing rib 11 and is connected to the inner panel 1 and the outer panel 2 of the hood.

[0057] The engine hood provided in this embodiment of the application has a supporting rib 3. The supporting rib 3 is set between the inner panel 1 and the outer panel 2 of the engine hood. The supporting rib 3 is set with a corresponding reinforcing rib 11 and is connected to the inner panel 1 and the outer panel 2 of the engine hood. In this way, the supporting rib 3 compensates for the strength of the reinforcing rib 11 with a hollow structure set in the inner panel 1 of the engine hood, thereby enhancing the overall rigidity and strength of the engine hood, thereby improving the load-bearing capacity of the engine hood and meeting the needs of users standing or sitting on the engine hood.

[0058] Furthermore, the setting of the supporting rib plate 3 allows the inner hood panel 1 to still meet the requirements of lightweight design. In this way, the load-bearing capacity of the engine hood is enhanced while the economy of the inner hood panel 1 is taken into account. There is no need to develop a new mold for the inner hood panel 1. In other words, a universal inner hood panel 1 can be used, which helps to reduce costs.

[0059] Reference Figure 3 In some embodiments, the reinforcing rib 11 includes a first rib 111 and a second rib 112 located on both sides of the first rib 111 in the left-right direction of the inner panel 1 of the hood. The area of ​​the hollowed-out area of ​​the first rib 111 is larger than the area of ​​the hollowed-out area of ​​the second rib 112.

[0060] Understandably, the first rib 111 is located between the two second ribs 112, and the area of ​​the hollowed-out region of the first rib 111 is larger than the area of ​​the hollowed-out region of the second rib 112. This allows the area where the first rib 111 is located to achieve lightweighting while ensuring structural rigidity. The second rib 112 is close to the boundary of the inner panel 1 of the hood, which makes the bonding strength between the reinforcing rib 11 and the part of the inner panel 1 of the hood located in the outer peripheral region 1b higher, so that the inner panel 1 of the hood has greater overall rigidity.

[0061] Reference Figure 3 The first rib 111 includes an outer ring rib 1111, an inner ring rib 1112 located inside the outer ring rib 1111, and a plurality of connecting ribs 1113 located between the outer ring rib 1111 and the inner ring rib 1112, with a hollow hole formed between two adjacent connecting ribs 1113.

[0062] Understandably, through the design of the outer ring rib 1111, the inner ring rib 1112 and multiple connecting ribs 1113, the structure of the first rib 111 can improve the structural rigidity of the inner panel 1 of the hood in this area while ensuring lightweight.

[0063] Specifically, refer to Figure 3 The outer ring rib 1111 is hexagonal in shape, and there are two connecting ribs 1113. Each connecting rib 1113 is located at the corner of the outer ring rib 1111. Thus, two adjacent connecting ribs 1113, the inner ring rib 1112, and the outer ring rib 1111 form a triangular structure, which makes the structure of the first rib 111 more stable and stronger.

[0064] It should be noted that the outer ring rib 1111, inner ring rib 1112 and multiple connecting ribs 1113 constituting the first rib 111 are integrally formed, thereby making the first rib 111 have good integrity and high structural strength.

[0065] Reference Figure 3The second rib section 112 includes a main rib plate 1121 and a secondary rib plate 1122 connected to each other. The main rib plate 1121 extends along the left-right direction of the inner plate 1 of the machine cover, and the main rib plate 1121 has multiple secondary rib plates 1122 on both sides of the inner plate 1 of the machine cover in the front-back direction. The secondary rib plates 1122 extend along the front-back direction of the inner plate 1 of the machine cover.

[0066] The main stiffening plates 1121 of the two second stiffening sections 112 and the two connecting stiffenings 1113 of the first stiffening section 111 are located on the same straight line extending in the left and right direction along the inner plate 1 of the machine cover.

[0067] Understandably, the second rib 112 is composed of a main rib plate 1121 and multiple secondary rib plates 1122, and the main rib plate 1121 and the two connecting ribs 1113 of the first rib 111 are located on the same straight line extending in the left and right direction along the inner plate 1 of the machine cover. This constitutes a "barbell" structural design, in which the two second ribs 112 act as "barbell plates", and the two connecting ribs 1113 of the first rib 111 act as "barbell bars", thereby connecting the first rib 111 and the second rib 112, so that the inner plate 1 of the machine cover forms a high-rigidity whole.

[0068] In addition, the two main stiffening plates 1121 and the two connecting stiffeners 1113 can also be regarded as the main stiffening ribs of the stiffening rib body 11, while the outer ring stiffener 1111, the inner ring stiffener 1112, the secondary stiffening plate 1122 and the remaining connecting stiffeners 1113 can be regarded as the branch stiffening ribs of the stiffening ribs. This can make up for the problem of the large blank area on both sides of the main stiffening ribs, thereby forming a strengthening effect on the inner plate 1 of the machine cover in all directions, and also forming multiple force transmission channels to disperse and reduce the risk of local stress concentration in the inner plate 1 of the machine cover.

[0069] The main stiffener 1121 has a perforated hole, and the perforation is formed between two adjacent secondary stiffeners 1122 on the same side of the main stiffener 1121 in the front-rear direction of the inner plate 1 of the hood. The area of ​​the perforation on the second stiffener 112 is smaller than the area of ​​the perforation on the first stiffener 111, and the width of the main stiffener 1121 is greater than the width of the connecting plate in the front-rear direction of the inner plate 1 of the hood, thus ensuring the strength of the reinforcing rib 11 on both sides in the left-right direction of the inner plate 1 of the hood.

[0070] It should be noted that the first rib 111 and the two second ribs 112 constituting the reinforcing rib 11 can be integrally formed, such as by stamping, which makes the reinforcing rib 11 have good integrity and high structural strength. In addition, the inner panel 1 of the machine cover can also be integrally formed, such as by stamping, so that the reinforcing rib 11 in the middle region 1a and the structure of the outer peripheral region 1b of the inner panel 1 of the machine cover are integrally stamped.

[0071] Reference Figure 4In some embodiments, the support rib 3 includes a rib body 31 and a plurality of collapsible support legs 32. The rib body 31 is provided corresponding to the reinforcing ribs 11 of the inner panel of the hood, and the support legs 32 are connected to the inner panel of the hood.

[0072] When the engine hood is subjected to force at its front end in the front-rear direction of the inner panel 1, the support leg 32 collapses to absorb energy.

[0073] Understandably, the main body 31 of the stiffener plate is connected to the inner panel 1 of the hood via the support leg 32, which provides support to increase the load-bearing capacity of the engine hood. Furthermore, when the front end of the engine hood is subjected to force, i.e., when a collision occurs, the support leg 32 can absorb energy through collapse, thereby reducing injury to pedestrians.

[0074] The support leg 32 can be formed during the stamping of the support rib plate 3, meaning that the rib plate body 31 and the support leg 32 are integrally stamped. The support leg 32 can be configured as a "Z-shaped" structure or a stepped structure to facilitate collapse and absorb energy during a frontal collision of the vehicle.

[0075] Among them, reference Figure 4 The main body 31 of the rib plate includes a first rib 311 and a plurality of second ribs 312. There are two first ribs 311. The first ribs 311 extend along the left and right direction of the inner plate 1 of the machine cover, and the two first ribs 311 are spaced apart in the front and back direction of the inner plate 1 of the machine cover. The second ribs 312 are disposed between the two first ribs 311, and the plurality of second ribs 312 are spaced apart in the left and right direction of the inner plate 1 of the machine cover.

[0076] Understandably, the main body 31 of the rib plate is reinforced in the front-rear and left-right directions by setting a first rib 311 and a second rib 312. The first rib 311 extends along the left-right direction of the inner plate 1 of the engine hood, and the second rib 312 extends along the front-back direction of the inner plate 1 of the engine hood, thereby improving the load-bearing capacity of the engine.

[0077] Refer again Figure 4 The aforementioned rib plate body 31 also includes a third rib 313 and a fourth rib 314. At least one third rib 313 is provided between two adjacent second ribs 312, and multiple fourth ribs 314 are provided. The fourth rib 314 is provided between two adjacent third ribs 313 or between a third rib 313 and a first rib 311.

[0078] Understandably, the first rib 311 and the second rib 312 constitute the main structure of the stiffening plate body 31, while the third rib 313 and the fourth rib 314 serve as branch structures of the stiffening plate body 31. This enhances the structural strength of the supporting stiffening plate 3, while forming more force transmission channels and reducing the risk of local stress concentration in the stiffening plate body 31.

[0079] Multiple third ribs 313 are provided between any two adjacent second ribs 312, and at least one fourth rib 314 is provided between any two adjacent third ribs 313, as well as between the outermost third rib 313 and the relatively close first rib 311. Thus, the third ribs 313 and the fourth ribs 314 form a "leaf vein" structure, with the third rib 313 serving as the main rib and the fourth rib 314 serving as the branch rib. The third rib 313 extends along the left-right direction of the inner panel 1 of the hood, while the fourth rib 314 extends along the front-back direction of the inner panel 1 of the hood.

[0080] It should be noted that the above-mentioned extension along the left and right or front and back directions of the inner panel 1 of the machine cover means that the length direction of each rib extends in a straight line along the left and right or front and back directions of the inner panel 1 of the machine cover, or has a certain inclination. In this case, the two ends of the rib in its length direction are not on the same straight line.

[0081] For example, refer to Figure 4 There are three second ribs 312, and the middle second rib 312 has a weight-reducing hole. There are two third ribs 313 between two adjacent second ribs 312, and at least one fourth rib 314 between two third ribs 313. At least one fourth rib 314 is also provided between the third rib 313 and the first rib 311.

[0082] It should be noted that the first rib 311, the second rib 312, the third rib 313 and the fourth rib 314 constituting the main body of the rib plate 31 are integrally formed, for example by stamping, which makes the main body of the rib plate 31 have good integrity and high structural strength.

[0083] In addition, the aforementioned stiffener body 31 is connected to the outer panel 2 of the machine cover by an expanding adhesive. The expanding adhesive can be selectively arranged at the connection points of each stiffener, thereby improving the connection stability between the stiffener body 31 and the outer panel 2 of the machine cover.

[0084] In some embodiments, refer to Figure 5 The aforementioned outer hood panel 2 is made of metal. That is to say, the outer hood panel 2 is a metal component, such as made of aluminum or steel, which can further improve the structural strength of the engine hood and thus improve its load-bearing capacity.

[0085] The outer panel 2 of the machine cover is a sheet metal part, and the outer panel 2 of the machine cover has a decorative part 21 formed by stamping.

[0086] Understandably, the decorative part 21 is stamped on the outer panel 2 of the hood, which not only reduces the number of parts and eliminates the installation steps, but also makes the decorative part 21 stronger and less prone to damage and aging compared to plastic.

[0087] It should be noted that the decorative part 21 mentioned above can be a structure that protrudes outward, a structure that is recessed inward, or a structure that is partially protruding outward and partially recessed inward, or other structures that create different visual effects. No specific restrictions are made here.

[0088] Reference Figure 5 and Figure 6 The outer panel 2 of the aforementioned machine cover is provided with an installation area 2a, which is used to install decorative parts 4.

[0089] Understandably, although the outer panel 2 of the hood itself is stamped and has a decorative part 21, in order to meet the user's personalized decoration needs, the outer panel 2 of the hood also has a mounting area 2a for installing decorative parts 4, which is convenient for installing decorative parts 4.

[0090] The mounting area 2a is designed as a groove. After the hood is installed on the vehicle, the bottom surface of the groove is inclined relative to the vertical direction. This makes it easier for the user to see the decorative part 4 from the front of the vehicle after installation, improving the decorative effect. Furthermore, the mounting groove can limit and accommodate the decorative part 4, making it more stable after installation.

[0091] Decorative component 4 can be a light panel, a brightly colored decorative panel, etc., without specific restrictions.

[0092] Reference Figures 1 to 6 An engine hood is provided as an example, which includes an inner hood panel 1, an outer hood panel 2, and a support rib 3.

[0093] The inner panel 1 of the hood has reinforcing ribs 11 that are hollowed out. The inner panel 1 is roughly symmetrical from left to right, and the axis of symmetry of the inner panel 1 is the central axis of the inner panel 1.

[0094] The reinforcing rib 11 includes a first rib portion 111 and second rib portions 112 located on both sides of the first rib portion 111 in the left-right direction of the inner plate 1 of the machine cover. The first rib portion 111 includes an outer ring rib 1111, an inner ring rib 1112 located inside the outer ring rib 1111, and a plurality of connecting ribs 1113 located between the outer ring rib 1111 and the inner ring rib 1112, with a hollow hole formed between two adjacent connecting ribs 1113.

[0095] The outer ring rib 1111 is hexagonal in shape, and there are two connecting ribs 1113. Each connecting rib 1113 is located at the corner of the outer ring rib 1111. Thus, two adjacent connecting ribs 1113, the inner ring rib 1112, and the outer ring rib 1111 form a triangular structure, which makes the structure of the first rib 111 more stable and stronger.

[0096] The aforementioned second rib section 112 includes a main rib plate 1121 and a secondary rib plate 1122 connected to each other. The main rib plate 1121 extends along the left-right direction of the inner panel 1 of the machine cover, and the main rib plate 1121 has multiple secondary rib plates 1122 on both sides of the inner panel 1 of the machine cover in the front-back direction. The secondary rib plates 1122 extend along the front-back direction of the inner panel 1 of the machine cover.

[0097] The main stiffening plates 1121 of the two second stiffening sections 112 and the two connecting stiffenings 1113 of the first stiffening section 111 are located on the same straight line extending in the left and right direction along the inner plate 1 of the machine cover.

[0098] The two main stiffening plates 1121 and the two connecting stiffeners 1113 can be regarded as the main stiffening ribs of the stiffening rib body 11, while the outer ring stiffener 1111, the inner ring stiffener 1112, the secondary stiffening plate 1122 and the remaining connecting stiffeners 1113 can be regarded as the branch stiffening ribs of the stiffening ribs. This can make up for the problem of the large blank area on both sides of the main stiffening ribs, thereby forming a strengthening effect on the inner plate 1 of the machine cover in all directions, and also forming multiple force transmission channels to disperse and reduce the risk of local stress concentration in the inner plate 1 of the machine cover.

[0099] The outer panel 2 of the hood is a sheet metal part, and the outer panel 2 has a decorative part 21 formed by stamping. In addition, the outer panel 2 has a mounting area 2a on the front side of the decorative part 21 in the front-rear direction of the inner panel 1, and the mounting area 2a is used to install the decorative part 4.

[0100] The supporting rib plate 3 includes a rib plate body 31 and multiple collapsible supporting legs 32. The rib plate body 31 is mainly set to correspond to the reinforcing ribs 11 of the inner panel of the hood, and the supporting legs 32 are connected to the inner panel of the hood.

[0101] When the engine hood is subjected to force at its front end in the front-rear direction of the inner panel 1, the support leg 32 collapses to absorb energy.

[0102] Among them, the main body of the stiffening plate 31 is mainly set to the first stiffening part 111 of the reinforcing rib 11, and the non-supporting leg 32 can be connected to the second stiffening part 112, thereby enhancing the load-bearing capacity of the engine hood at the first stiffening part 111 of the inner plate of the hood.

[0103] The main body 31 of the rib plate includes a first rib 311 and three second ribs 312. There are two first ribs 311. The first ribs 311 extend along the left and right direction of the inner plate 1 of the machine cover, and the two first ribs 311 are spaced apart in the front and back direction of the inner plate 1 of the machine cover. The second ribs 312 are disposed between the two first ribs 311, and the three second ribs 312 are spaced apart in the left and right direction of the inner plate 1 of the machine cover.

[0104] The aforementioned stiffening plate body 31 also includes a third stiffener 313 and a fourth stiffener 314, with two third stiffeners 313 disposed between two adjacent second stiffeners 312. Among them, a fourth stiffener 314 is disposed between two third stiffeners 313, and one or two fourth stiffeners 314 are disposed between the third stiffener 313 and the first stiffener 311.
