Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to a hinge reinforcement plate and a vehicle. Background Art

[0002] With the continuous development of automotive technology, people's requirements for vehicle performance are becoming increasingly higher, such as the high requirements for the anti-leaning performance of vehicle hoods. In traditional vehicles, hinge reinforcement plates are installed between the inner and outer panels of the hood and are generally welded to the inner panel. They mainly strengthen the hinge mounting position of the hood to prevent the rear end of the hood from vibrating severely or even causing cracks in this area due to insufficient strength at the hood hinge during long driving or on bumpy roads. However, this hinge reinforcement plate only provides local reinforcement and is difficult to achieve effective anti-leaning performance, especially for hoods with large coverage areas that integrate fender functions. Summary of the Invention

[0003] The present invention aims to solve the problem of how to improve the anti-leaning performance of the cover in the related art to a certain extent.

[0004] In order to solve the above problems at least to a certain extent, in the first aspect, the present invention provides a hinge reinforcement plate for being arranged between the inner plate and the outer plate of the machine cover, which includes a plate body, and a hinge mounting area is provided on the plate body, and the rear end of the plate body is used to extend backward from the hinge mounting area to a position close to the rear end of the inner plate, and the front end of the plate body is used to extend forward from the hinge mounting area to a calibrated position of the inner plate.

[0005] Optionally, a lock mounting area is provided on the inner panel near the front end, and the calibration position is provided near the lock mounting area in the front-to-rear direction; and / or, fender functional areas are provided on both sides of the inner panel along the left-right direction, and the calibration position is located in front of the fender functional area.

[0006] Optionally, the plate body includes an inner connecting area, an intermediate connecting area and an outer connecting area distributed in sequence along the left and right directions, the inner connecting area and the outer connecting area are both used to adhere to and connect with the inner plate, and the plate body is used to form a first cavity by enclosing the inner plate in the intermediate connecting area.

[0007] Optionally, the middle connecting area is used to bulge relative to the inner connecting area and the outer connecting area and form a first groove-shaped structure opening toward the inner plate, and the first groove-shaped structure is used to enclose the first cavity with the inner plate.

[0008] Optionally, the inner plate includes a connected top plate portion and side plate portions located on both sides of the top plate portion along the left-right direction;

[0009] In the cross section, a portion of the intermediate connection area is spaced apart from the outside of the side plate portion, and a portion of the intermediate connection area is spaced apart from the upper side of the top plate portion;

[0010] And / or, the top plate portion is provided with an intermediate bulging structure at a position spaced apart from the side plate portion; the inner connecting area includes an inner connecting edge and a transition connecting area located between the inner connecting edge and the intermediate connecting area, and the inner connecting edge is used to fit and weld with the intermediate bulging structure; the transition connecting area is recessed relative to the intermediate connecting area and the inner connecting edge, and at least a part of the transition connecting area is used to connect with the non-bulging part of the top plate portion; the hinge mounting area is provided in the transition connecting area.

[0011] Optionally, the plate body is used to fit and connect with the top plate portion at the hinge mounting area; or, the plate body is used to be spaced apart from the top plate portion in the hinge mounting area, and to fit and connect with the top plate portion on at least the front and rear sides of the hinge mounting area in the transition connection area.

[0012] Optionally, one or more deformation guiding structures are provided on the plate body. When the deformation guiding structures are provided in plurality, the plurality of deformation guiding structures are spaced apart along the front-to-back direction; the deformation guiding structure is used to guide the plate body to undergo energy-absorbing deformation at the deformation guiding structure.

[0013] Optionally, the deformation guiding structure includes one or more of a guiding groove, a weakened hole and a notched groove;

[0014] The guide groove is formed by the outward expansion of the plate body; the weakened hole is opened on the plate body and is spaced from the edge of the plate body along the left and right directions; the notch groove is set on the edge of the plate body along the left and right directions, and both sides of the notch of the notch groove are used to connect with the inner plate;

[0015] When the deformation guiding structure includes a plurality of the guiding grooves, the weakened holes and the notch grooves, the positions of the plurality of structures correspond to each other.

For example, the front end of the plate body is located in the middle front portion of the inner panel in the front-to-back direction. The hinge reinforcement plate has a large span in the front-to-back direction, and the force transmitted by the hinge to the hinge mounting area can be diffused in the front-to-back direction, thereby enhancing the rigidity of the hinge mounting area and the hood's resistance to side leaning and pull-down. In addition, the rear end of the plate body is close to the rear end of the inner panel, which can enhance the rigidity of the rear corner of the inner panel. Even if the rear end of the inner panel is significantly separated from the hinge mounting area due to, for example, the integration of a fender functional area at the rear, insufficient rigidity at the rear corner can be avoided. The hinge reinforcement plate covers a relatively large area in the front-to-rear direction along the upper edge of the inner panel, and can achieve better resistance to side leaning and pull-down performance, and can be suitable for wide coverage, such as hoods with integrated fender functions.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] In the drawings, the Z-axis represents the vertical direction, that is, the up-down position, and the positive direction of the Z-axis (that is, the direction of the arrow on the Z-axis) represents the up direction, and the negative direction of the Z-axis (that is, the direction opposite to the positive direction of the Z-axis) represents the down direction; the X-axis in the drawings represents the horizontal direction and is designated as the left-right position, and the positive direction of the X-axis (that is, the direction of the arrow on the X-axis) represents the right direction, and the negative direction of the X-axis (that is, the direction opposite to the positive direction of the X-axis) represents the left direction; the Y-axis in the drawings represents the front-back position, and the positive direction of the Y-axis (that is, the direction of the arrow on the Y-axis) represents the front side, and the negative direction of the Y-axis (that is, the direction opposite to the positive direction of the Y-axis) represents the rear side; it should be noted that the aforementioned Z-axis, Y-axis, and X-axis are merely for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0032] It should be noted that Figure 5 The AA section is the section passing through the deformation guiding structure 15 , the BB section is the section passing through the leakage hole 18 , the CC section is the section passing through the third welding portion 1212 , and the DD section is the section passing through the mounting hole 1211 , which will not be described one by one later.

[0033] like Figures 1 to 9As shown, an embodiment of the present invention provides a hinge reinforcement plate, which is used to be arranged between the inner plate 2 and the outer plate of the machine cover. The hinge reinforcement plate includes a plate body 1, and a hinge installation area 121 is provided on the plate body 1. The rear end of the plate body 1 is used to extend backward from the hinge installation area 121 to a rear end position close to the inner plate 2, and the front end of the plate body 1 is used to extend forward from the hinge installation area 121 to a calibrated position of the inner plate 2.

[0034] The method for mounting the hinge in hinge mounting area 121 is not limited and may employ relevant technologies. For example, hinge mounting area 121 may be provided with a connection interface, wherein the connection structure includes one or more mounting holes 1211, and the hinge connection base is connected to the mounting holes 1211 via a connector, which will not be described in detail here. It should be noted that in the case of a hood, two hinge reinforcement plates are generally provided, one on the left and one on the right. Only the left hinge reinforcement plate is shown in the figure.

[0035] Exemplarily, a latch mounting area 212 is provided on the inner panel 2 near the front end, and the marking position is provided near the latch mounting area 212 in the front-to-back direction.

[0036] For example, the front end of the inner panel 2 is provided with a latch mounting area 212 on both the left and right sides, and the inner panel 2 is connected to the latch mounting area 212 with a latch reinforcement plate 3. When the hinge reinforcement plate is connected to the left and right sides of the inner panel 2, the front end of the hinge reinforcement plate can be located at the rear end of the latch mounting area 212 (see FIG. 1 ). Figure 1 and Figure 3 ).

[0037] like Figure 2 As shown, exemplarily, when the inner panel 2 is provided with fender functional areas 221 on both sides along the left-right direction, the calibration position is located in front of the fender functional area 221 .

[0038] For example, in the front-rear direction, the calibration position may be located between the fender functional area 221 and the latch installation area 212 .

[0039] It should be noted that the hinge reinforcement plate of this specification can be used for the inner panel 2 integrated with the fender functional area 221 , and can also be used for the inner panel 2 not integrated with the fender functional area 221 .

[0040] This specification will later use the previous scenario as an example to illustrate the implementation and effects of the present invention. In this case, the inner panel 2 exemplifies the following: it comprises an integrally connected reinforcement edge, a top panel portion 21, and side panels 22 located on either side of the top panel portion 21 in the left-right direction. The reinforcement edge circumscribes the inner panel 2 and is typically reinforced by a concave-convex stepped structure. The side panels 22 are provided with a fender functional area 221, and the reinforcement edge includes a side reinforcement edge 23 located at the bottom of the side panels 22 (this embodiment will be used to illustrate the present invention later).

[0041] In this embodiment, the hinge reinforcement panel's body 1 is not only provided with a hinge mounting area 121, but also has a rear end extending rearward from the hinge mounting area 121 to a position near the rear end of the inner panel 2. The front end of the body 1 also extends forward from the hinge mounting area 121 to a designated position on the inner panel 2. For example, the front end of the body 1 is located at the center-front portion of the inner panel 2 in the front-to-back direction. This hinge reinforcement panel has a large front-to-back span, allowing the forces transmitted by the hinge to the hinge mounting area 121 to be dispersed in the front-to-back direction. This enhances the rigidity of the hinge mounting area 121 and improves the hood's resistance to side leaning and downward pull. Furthermore, the rear end of the body 1 is located near the rear end of the inner panel 2, enhancing the rigidity of the rear corners of the inner panel 2. This prevents insufficient rigidity at the rear corners, even if the rear end of the inner panel 2 is significantly separated from the hinge mounting area 121 due to, for example, the integration of a fender functional area 221 at the rear. The hinge reinforcement plate of the present invention covers a relatively large range along the front-to-back direction on the inner plate 2, and can achieve good resistance to side leaning and pull-down performance, and can be applied to hoods with a wide coverage area, such as those with integrated fender functions.

[0042] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 8 As shown, optionally, the plate body 1 includes an inner connecting area (not shown in the figure, which includes at least an inner connecting edge 11), an intermediate connecting area 13 and an outer connecting area 14 distributed in sequence along the left and right directions. The inner connecting area and the outer connecting area 14 are both used to fit and connect with the inner plate 2. The plate body 1 is used to enclose the inner plate 2 in the intermediate connecting area 13 to form a first cavity 16 ( Figure 8 shown).

[0043] Specifically, the inner connection area is set at the inner end of the panel body 1 in the left-right direction, that is, the end close to the center of the inner panel 2 in the left-right direction, and the outer connection area 14 is set at the outer end of the panel body 1 in the left-right direction, that is, the end close to the outside of the vehicle.

[0044] It should be noted that in the front-back direction, the inner connection area and / or the outer connection area 14 can be attached to the inner plate 2 in an alternating interval manner, and the specific connection method can adopt related technologies, such as welding connection.

[0045] As Figures 1 to 3 shown, exemplarily, taking the outer connection area 14 as an example, the outer connection area 14 can include a continuous area with equal width at various positions in the front-back direction, which can be the edge part of the plate body 1 close to the outside. The outer edge of the outer connection area 14 extends to the side strengthening edge 23 of the inner plate 2, and the contour line formed by the extension of its outer edge in the front-back direction is basically consistent with the inner contour line of the side strengthening edge 23. At this time, the outer connection area 14 includes a plurality of first welding parts 141 in the front-back direction. The first welding parts 141 can be provided with a plate-like structure. At this time, in the front-back direction, a structure protruding relative to the plate-like structure can be provided between adjacent first welding parts 141 (such as the guiding groove 151 described later. In the front-back direction, the guiding groove 151 and the first welding parts 141 are arranged at alternating intervals). At this time, while ensuring the connection stability, it can be avoided that the entire outer connection area 14 needs to be attached to the inner plate 2, the processing precision requirements can be reduced, and furthermore, the local stiffness of the outer connection area 14 can be enhanced to a certain extent, such as the bending resistance performance in the up-down direction, and the material consumption can be reduced under the condition of consistent performance.

[0046] In this way, both the inner connection area and the outer connection area 14 of the plate body 1 are attached to and connected to the inner plate 2, such as by welding. The plate body 1 and the inner plate 2 enclose a first cavity 16 in the middle connection area 13. Due to the existence of the first cavity 16, when the hood receives a leaning force from one side of the first cavity 16, such as from the left-right direction, the first cavity 16 can improve the overall stiffness and strength of its position without increasing the thickness of the hinge reinforcement plate and the inner plate 2, and improve the anti-leaning and anti-denting performance of the hood.

[0047] It should be noted that the first cavity 16 can include the cavity part formed by the depression of the inner plate 2, which will not be elaborated here.

[0048] As Figure 5 and Figure 7 shown, optionally, the middle connection area 13 bulges relative to the inner connection area and the outer connection area 14 and forms a first groove-like structure 131 with an opening facing the inner plate 2. The first groove-like structure 131 is used to enclose the first cavity 16 with the inner plate 2.

[0049] At this time, in the cross-section, that is, in the XY plane, the plate body 1 as a whole forms a "U" - shaped structure, and the first groove-like structure 131 corresponds to the main part of the "U".

[0050] In this way, the first groove-shaped structure 131 formed by the hinge reinforcement plate and the inner plate 2 can be combined to form the first cavity 16, which has a simple structure and strong practicality.

[0051] like Figure 5 and Figure 8 As shown, optionally, in the cross section, part of the middle connection area 13 is used to be spaced apart on the outside of the side plate portion 22 , and part of the middle connection area 13 is used to be spaced apart on the upper side of the top plate portion 21 .

[0052] Specifically, in the cross section, the first groove-shaped structure 131 is configured to extend along a first transition line L1 between the top plate portion 21 and the side plate portion 22 in the front-to-back direction (the first transition line L1 is a reference to FIG. Figure 3 ).

[0053] That is, the first cavity 16 is surrounded by the top plate portion 21 , the side plate portion 22 and the intermediate connecting structure.

[0054] At this time, on the one hand, the first cavity 16 is moved downward relative to the position of the inner panel 2, and the reinforced part of the inner panel 2 can be moved downward, so that the reinforcement of the lower end position of the side panel portion 22 can be enhanced. For example, when the inner panel 2 is integrated with the fender functional area 221, the anti-side leaning performance of the fender functional area 221 can be enhanced to a certain extent; on the other hand, the outer space of the side panel portion 22 of the inner panel 2 is used to form the first cavity 16, which reduces the large space occupied by the hinge reinforcement plate above the inner panel 2, and the spatial structure layout is reasonable and practical.

[0055] like Figure 2 and Figure 3 As shown, the top plate portion 21 is provided with a middle bulging structure 211 at a position spaced apart from the side plate portion 22. The middle bulging structure 211 can be used to connect with the outer plate of the hood, which can adopt relevant technology and will not be described in detail here.

[0056] like Figures 1 to 4 As shown, optionally, at this time, the inner connecting area includes an inner connecting edge 11 and a transition connecting area 12 located between the inner connecting edge 11 and the intermediate connecting area 13, and the inner connecting edge 11 is used to fit and weld with the intermediate bulging structure 211 (specifically, it can be connected to the side wall or top wall of the intermediate bulging structure 211); the transition connecting area 12 is recessed relative to the intermediate connecting area 13 and the inner connecting edge 11, and at least a portion of the transition connecting area 12 is used to connect with the non-bulging portion of the top plate portion 21; a hinge mounting area 121 is provided in the transition connecting area 12.

[0057] like Figure 4As shown, similar to the outer connecting area 14 , the inner connecting edge 11 includes a plurality of second welding portions 111 arranged along its extension direction, such as the front-to-back direction. The second welding portions 111 may include a plate-like structure similar to the first welding portions 141 .

[0058] like Figure 4 、 Figure 6 and Figure 8 As shown, the transition connection area 12 is recessed relative to the intermediate connection area 13 and the inner connection edge 11, and the transition line at the transition between the transition connection area 12 and the intermediate connection area 13 is the second transition line L2, and the transition line between the intermediate connection area 13 and the outer connection area 14 is the third transition line L3.

[0059] like Figure 6 and Figure 8 As shown, it should be noted that, similar to the way the outer connection area 14 is connected to the inner panel 2, the connection between the transition connection area 12 and the inner panel 2 can be spaced in the front-to-back direction. For example, the transition connection area 12 includes a plurality of third welding portions 1212 spaced along the front-to-back direction, thereby taking into account both the connection requirements and the reduction of the processing accuracy requirements, which is convenient for example for the subsequent assembly process.

[0060] In this way, the inner end of the hinge reinforcement plate is connected to the intermediate bulging structure 211, and the hinge reinforcement plate covers a larger area in the left-right direction, thereby enhancing the hinge reinforcement plate's resistance to leaning and denting. The transition region 12 is also recessed relative to the intermediate connecting region 13 and the inner connecting edge 11. In a cross-section passing through the connection between the transition region 12 and the inner panel 2, a second groove structure is formed, with the transition region 12 as the bottom wall and the intermediate connecting region 13 and the inner connecting edge 11 as the side edges. This second groove structure enhances the rigidity of the transition region 12, particularly in the front-to-back direction, thereby, together with the first trough-like structure 131, improving the mechanism's resistance to downward pull. Furthermore, this arrangement allows the inner edge of the first trough-like structure 131 (which can be roughly understood as the aforementioned second transition line L2) to shift outward in the left-right direction, preventing the left-right span transition of the first trough-like structure 131 from affecting its resistance to denting and side leaning. In addition, a hinge installation area 121 is provided in the transition connection area 12 , which has a reasonable location and layout and is highly practical.

[0061] like Figure 9 As shown, optionally, the board body 1 is used to be attached to and connected to the top board portion 21 at the hinge installation area 121.

[0062] In this way, the plate body 1 is in a fitting connection with the top plate portion 21 in the hinge installation area 121, such as by welding, so that the thickness of the hinge action position is thickened to ensure its rigidity.

[0063] It should be noted that, unlike the above-mentioned manner in which the plate body 1 is adhered to and connected to the top plate portion 21 at the hinge mounting area 121, in another embodiment, the plate body 1 is used to be spaced apart from the top plate portion 21 in the hinge mounting area 121, and is used to be adhered to and connected to the top plate portion 21 on at least the front and rear sides of the hinge mounting area 121 in the transition connection area 12 (not shown in this scheme figure).

[0064] like Figure 9 As shown, for example, the above-mentioned third welding parts 1212 are provided on both the front and rear sides (and also on the left and right sides) of the area where the mounting hole 1211 of the hinge mounting area 121 is located. In this way, a third cavity can be formed between the transition connection area 12, the third welding part 1212 and the inner plate 2. Due to the setting of the third cavity, at the moment of being subjected to the force transmitted by the hinge, the hinge mounting area 121 can undergo a small elastic deformation to absorb the impact kinetic energy, and then quickly transmit the force to the surrounding area through the third welding structure on the side of the hinge mounting area 121, which can improve its impact resistance to a certain extent without increasing consumables. It will not be described in detail here.

[0065] like Figures 6 to 9 As shown, optionally, along the front-to-back direction, at one or more third welding portions 1212 , in a cross section (XY plane) passing through the third welding portion 1212 , the transition connection area 12 , the inner connecting edge 11 and the top plate portion 21 of the inner plate 2 form a second cavity 17 .

[0066] Exemplarily, along the front-to-back direction, the transition connection area 12 forms a step structure at least at the connection between the hinge installation area 121 and the inner connection edge 11 .

[0067] like Figure 2 、 Figure 7 and Figure 8 As shown, the step structure includes a step surface 1213 spaced apart from the third welding portion 1212 in the vertical direction. In the cross section (XY plane) passing through the third welding portion 1212 , the step surface 1213 is used to form a second cavity 17 with the inner panel 2 .

[0068] Specifically, in this cross section, a second cavity 17 is formed between the step structure and the inner panel 2 .

[0069] In this way, on the one hand, the processing accuracy of the connection portion between the transition connection area 12 and the inner connection edge 11 can be reduced, and on the other hand, the overall force reliability of the connection portion can be enhanced through the second cavity 17 .

[0070] like Figure 4 and Figure 6As shown, in the above embodiment, optionally, one or more deformation guiding structures 15 are provided on the plate body 1. When the deformation guiding structure 15 is provided in plurality, the plurality of deformation guiding structures 15 are spaced apart along the front-to-back direction; the deformation guiding structure 15 is used to guide the plate body 1 to undergo energy absorption deformation at the deformation guiding structure 15.

[0071] Specifically, the deformation guiding structure 15 is generally a weakened area with smaller rigidity of the plate body 1, which can be deformed preferentially when subjected to a collision. Specifically, deformation occurs at the deformation guiding structure 15 so that the front and rear parts can change their relative positions, thereby absorbing the collision energy. For example, the front part can swing downward relative to the rear part.

[0072] In this way, when the hood is impacted, the hinge reinforcement plate's deformation guide structure 15 can deform in a predetermined manner, absorbing energy and reducing damage to the passenger compartment. If multiple deformation guide structures 15 are provided in the fore-aft direction, each deformation guide structure 15 can deform at different impact locations or impact forces. The deformation of each deformation guide structure 15 can also vary depending on the location of the impact. Furthermore, this can increase the overall intrusion capacity of the corresponding hinge reinforcement plate during a collision, enhancing energy absorption.

[0073] like Figure 4 and Figure 6 As shown, optionally, the deformation guiding structure 15 includes one or more of a guiding groove 151 , a weakened hole 152 and a notched groove 153 ;

[0074] The guide groove 151 is formed by the outward expansion of the plate body 1; the weakened hole 152 is opened on the plate body 1 and is spaced from the edge of the plate body 1 along the left and right directions; the notch groove 153 is provided on the edge of the plate body 1 along the left and right directions, and both sides of the notch of the notch groove 153 are used to connect with the inner plate 2;

[0075] When the deformation guiding structure 15 includes a plurality of the guiding grooves 151 , the weakened holes 152 and the notched grooves 153 , the positions of the plurality of the plurality of the guiding grooves 151 correspond to each other.

[0076] by Figure 4 Taking the case where the transition connection region 12 is provided on the panel body 1 as an example, three deformation guiding structures 15 are provided on the panel body 1. The three deformation guiding structures 15 are all located between the front end of the panel body 1 and the hinge mounting region 121. Each deformation guiding structure 15 includes a guide groove 151, a weakened hole 152, and a notched groove 153. In the front-to-back direction, the guide groove 151, weakened hole 152, and notched groove 153 of each deformation guiding structure 15 are substantially located in the same region (this region is a preset deformation region, and the extension path of the deformation region can be set to be curved as needed).

[0077] like Figure 5 and Figure 6 As shown, exemplarily, the transition connection area 12 and the outer connection area 14 are provided with guide grooves 151, the intermediate connection area 13 is provided with weakened holes 152 at the transition position connected to the transition connection area 12 and the transition position connected to the outer connection area 14, and the edge position of the inner connection edge 11 is provided with a notch groove 153, and the two side walls of the notch of the notch groove 153 form the second welding portion 111 described above.

[0078] At this time, preferably, the contours of the notch groove 153 and the weakened hole 152 are smoothly transitioned and connected, for example, the side wall of the notch groove 153 is transitionally connected to the rounded corners of other parts.

[0079] In this way, the deformation guiding structure 15 has a simple structure and can achieve better energy absorption and deformation. When the deformation guiding structure 15 includes multiple guide grooves 151, weakened holes 152, and notched grooves 153, the positions of the guide grooves 151, weakened holes 152, and notched grooves 153 can be arranged according to the structural characteristics of the plate body 1. For example, providing a guide groove 151 in the portion that mainly mates with the inner panel 2, such as the transition connection area 12, can not only serve the purpose of deformation guidance, but also, to a certain extent, prevent the transition connection area 12 from completely mates with the top plate portion 21 of the inner panel 2 through the provision of the guide groove 151, which can reduce the processing accuracy requirements for the transition connection area 12 of the hinge reinforcement plate to a certain extent. Providing a weakened hole 152 at the connection between the intermediate connection area 13, the transition connection area 12, and the outer connection area 14 can, on the basis of deformation guidance, avoid the accumulation of material at the connection caused by the formation of the guide groove 151. The notch groove 153 is provided at the inner connecting edge 11 , and the connection stability thereof can be ensured by connecting the notch sides of the notch groove 153 with the inner plate 2 , and the processing accuracy requirement can also be reduced.

[0080] In the above embodiment, the middle connecting region 13 is also used for adhesive connection with the outer panel. For example, adhesive grooves can be provided on the top or side of the middle connecting region 13, and the adhesive grooves can be spaced apart along the front-to-back direction.

[0081] Of course, the board body 1 can also be connected to the outer plate glue at other positions, such as the outer connecting area 14, which can be determined according to actual needs and will not be described in detail here.

[0082] Other structures can be set on the hinge reinforcement plate as needed, which is not a limitation. For example, a buffer block avoidance hole 1214, a leakage hole 18, etc. can be set on it, and a avoidance structure for avoiding the internal partial convex structure can also be set, which will not be described in detail here.

[0083] Another embodiment of the present invention provides a machine cover, comprising an outer panel, an inner panel 2 and the hinge reinforcement plate of the above embodiment, wherein the hinge reinforcement plate is disposed between the outer panel and the inner panel 2 .

[0084] There are two hinge reinforcement plates, which are arranged opposite to each other along the left-right direction, and are connected to the inner plate 2 .

[0085] Yet another embodiment of the present invention provides a vehicle, comprising the hood according to the above embodiment.
