Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, and more specifically, to a hood reinforcement plate structure, a hood, and a vehicle. Background Technology
[0002] Currently, in vehicle hood structures, the reinforcement of the locking area typically employs a split design. The outer hood support plate is positioned between the outer and inner hood panels, its lower part welded to the inner panel, and its upper part bonded with adhesive to provide elastic support to the outer panel. The hood lock reinforcement plate, on the other hand, is independently installed and welded separately to the inner hood panel, serving to install the latch and transmit the locking load. These two components are independently formed, manufactured using their respective molds and fixtures, and then sequentially welded to the inner hood panel, forming a localized reinforcement system for the hood lock area.
[0003] However, the above-mentioned split structure has obvious shortcomings: on the one hand, the hood lock reinforcement plate and the hood outer plate support plate require separate development of stamping dies and inspection fixtures, resulting in a large number of tooling and high development costs; on the other hand, the hood lock reinforcement plate and the hood outer plate support plate need to be installed in two separate parts, which not only increases the assembly time, but also makes the discontinuous arrangement of parts prone to poor structural continuity. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a hood reinforcement plate structure, a hood, and a vehicle.
[0005] In a first aspect, the present invention provides a hood reinforcement plate structure, comprising an integrally formed reinforcement plate body, wherein the reinforcement plate body is provided with a protruding structure, the protruding structure being formed by a local portion of the reinforcement plate body recessed along the thickness direction of the reinforcement plate body, the end face of the protruding structure away from the reinforcement plate body being configured to connect with the inner plate of the hood and a latch; the end face of the reinforcement plate body opposite to the protruding structure being configured to support the outer plate of the hood.
[0006] Optionally, the reinforcing plate body has a first adhesive groove structure on the end face opposite to the protruding structure.
[0007] Optionally, the hood reinforcement plate structure further includes a support plate disposed on the end face of the reinforcement plate body opposite to the protrusion structure, and at least a portion of the support plate is projected onto the reinforcement plate body within the outline of the protrusion structure and is configured to support the outer hood plate.
[0008] Optionally, the reinforcing plate body is provided with a through first weight-reducing hole along the thickness direction; the support plate is configured to be formed by stamping using the sheet material within the first weight-reducing hole.
[0009] Optionally, the support plate includes a first plate, a second plate, and a third plate, wherein the first plate and the third plate are both bent plates; one end of the first plate and one end of the third plate are connected to the reinforcing plate body; the other ends of the first plate and the third plate are bent and extended and respectively connected to the opposite ends of the second plate; the second plate is configured to support the outer panel of the machine cover.
[0010] Optionally, both the bends of the first plate and the bends of the third plate are provided with reinforcing structures; the reinforcing structures include at least one of the following: protrusions, reinforcing plates, or reinforcing ribs. And / or, the second plate has a second adhesive groove structure on the end face opposite to the protruding structure; And / or, the second plate has a through second weight-reducing hole along the thickness direction.
[0011] Optionally, the end face of the reinforcing plate body away from the protrusion structure is provided with a mounting groove at the edge of the protrusion structure, the first plate and the third plate are disposed in the corresponding mounting groove, and the projection of the second plate on the reinforcing plate body is located within the outline range of the protrusion structure.
[0012] Optionally, the reinforcing plate body is provided with a plurality of support feet on its periphery, and the reinforcing plate body is configured to be connected to the inner panel of the hood through the plurality of support feet.
[0013] Secondly, this utility model provides a machine cover, including an outer panel, an inner panel, and a reinforcing plate structure as described above.
[0014] Thirdly, this utility model provides a vehicle including the hood described above.
[0015] Compared with related technologies, the beneficial effects of this utility model are as follows: The reinforcing plate body is integrally molded, with some parts having recessed protrusions along its thickness. During assembly, the end face of the protrusions away from the reinforcing plate body can connect with the inner panel of the hood and the latches, while the end face of the reinforcing plate body away from the protrusions can support the outer panel of the hood. Thus, compared to the traditional separate outer panel support plate and hood lock reinforcing plate, the reinforcing plate body integrates the two into one, requiring only one set of molds and one set of inspection tools for manufacturing, greatly reducing tooling and development costs. The latch fixing and outer panel support are completed simultaneously with a single positioning weld, eliminating the need for secondary assembly and reducing assembly time. At the same time, the reinforcing plate body has no weld seams or lap joints. The latch load is directly diffused to the entire plate through the protrusions and then evenly transferred to the inner and outer panels of the hood, resulting in continuous force flow and no stress concentration, effectively improving structural strength.

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.
[0021] In related technologies, the reinforcement of the hood lock area still follows the "two-plate" approach: one outer hood support plate is sandwiched between the outer hood plate 300 and the inner hood plate 200, with its lower edge spot-welded to the inner hood plate 200 and its upper edge glued to support the outer plate; the other hood lock reinforcement plate is welded separately to the inner hood plate 200 to install the latch and withstand pulling. Both plates are molded separately, inspected separately, and stamped separately, and then welded to the inner hood plate 200 in two stages to complete the reinforcement.
[0022] However, the aforementioned split structure requires two sets of molds and two sets of inspection tools, resulting in high development costs; and during installation, it requires two loading and two positioning operations, which forces the production line cycle to be lengthened; at the same time, there is a gap between the outer support plate of the machine cover and the reinforcing plate of the machine cover lock, which prevents the continuous transmission of the lock load, reduces rigidity, and causes stress concentration.
[0023] To address the aforementioned problems, this utility model provides a machine hood reinforcement plate structure, comprising an integrally formed reinforcement plate body 100, a protruding structure 101 on the reinforcement plate body 100, the protruding structure 101 being formed by a partial portion of the reinforcement plate body 100 recessed along the thickness direction of the reinforcement plate body 100, the end face of the protruding structure 101 away from the reinforcement plate body 100 being configured to connect with the inner plate 200 of the machine hood and a latch; the end face of the reinforcement plate body 100 opposite to the protruding structure 101 being configured to support the outer plate 300 of the machine hood.
[0024] Specifically, the reinforcing plate body 100 is a one-piece molded part. During the production process, the metal plate is processed by stamping to form the reinforcing plate body 100. For example... Figure 1 As shown, a protruding structure 101 is recessed in the middle part of the reinforcing plate body 100 along the thickness direction of the reinforcing plate body 100. The shape of the protruding structure 101 matches the shape of the recessed portion 201 on the inner panel 200 of the hood. For example, the shapes of the protruding structure 101 and the recessed portion 201 on the inner panel 200 of the hood can be matching rectangles, trapezoids, or other irregular shapes. The end face of the protruding structure 101 away from the reinforcing plate body 100 is welded to the recessed portion 201 of the inner panel 200 of the hood. The latch is U-shaped and is welded to the end face of the protruding structure 101 away from the reinforcing plate body 100, and passes through the hole in the recessed portion 201 to exit the inner panel 200 of the hood. The end face of the reinforcing plate body 100 away from the protruding structure 101 (i.e., the end face of the reinforcing plate body 100 facing the outer panel 300 of the hood) is attached to the outer panel 300 of the hood, thereby supporting the outer panel 300 of the hood.
[0025] In this optional embodiment, the reinforcing plate body 100 is integrally formed, and a protruding structure 101 is formed by recessing a portion of the reinforcing plate body 100 along the thickness direction. During assembly, the end face of the protruding structure 101 away from the reinforcing plate body 100 can be connected to the inner panel 200 of the hood and the latch, while the end face of the reinforcing plate body 100 away from the protruding structure 101 can support the outer panel 300 of the hood. Thus, compared with the traditional separate outer panel support plate and hood lock reinforcing plate, the reinforcing plate body 100 integrates the two into one, requiring only one set of molds and one set of inspection tools for manufacturing, greatly reducing tooling and development costs. The latch fixing and outer panel support are completed simultaneously with one positioning welding, eliminating the need for secondary parts installation and reducing assembly time. At the same time, the reinforcing plate body 100 has no weld seams or lap gaps. The latch load is directly diffused to the entire plate through the protrusion and then evenly transferred to the inner panel 200 and the outer panel 300 of the hood. The force flow is continuous and there is no stress concentration, which effectively improves the structural strength.
[0026] In other embodiments, the reinforcing plate body 100 may also have protrusions 101 at other locations, such as both ends of the reinforcing plate body 100. This is not a limitation and depends on the actual needs.
[0027] Optionally, the end face of the reinforcing plate body 100 facing away from the protrusion structure 101 is provided with a first adhesive groove structure 102.
[0028] Specifically, such as Figure 2 As shown, the outer contour of the end face of the reinforcing plate body 100 away from the protrusion structure 101 is arc-shaped. The portion of the end face of the reinforcing plate body 100 away from the protrusion structure 101 near the edge and the portion near the protrusion structure 101 are provided with a first glue groove structure 102. The number of first glue grooves is not specifically limited and depends on actual needs. The shape of the first glue groove structure 102 can be a strip, a rectangle, or a circle, etc.
[0029] In this optional embodiment, since the end face of the reinforcing plate body 100 facing away from the protruding structure 101 directly faces the outer panel 300 of the hood, and the end face is connected to the outer panel 300 of the hood by an expanding adhesive, after the first adhesive groove structure 102 is punched out on the end face, the expanding adhesive can be constrained within the first adhesive groove structure 102: this can prevent the adhesive from overflowing and causing waste and pollution, and can also ensure that the adhesive layer thickness is uniform, so that the outer panel 300 of the hood can obtain continuous and stable elastic support; at the same time, the bottom plane of the groove and the adhesive layer form a larger bonding area, which improves the shear strength, and the anti-dent and vibration reduction performance of the outer panel 300 of the hood is improved simultaneously.
[0030] Furthermore, the first adhesive groove structure 102 is also formed by a local portion of the reinforcing plate body 100 recessed along the thickness direction of the reinforcing plate body 100. Thus, in addition to accommodating the expanding adhesive, the first adhesive groove structure 102 can also enhance the strength of the reinforcing plate body 100 at this location.
[0031] Optionally, the hood reinforcement plate structure further includes a support plate 400, which is disposed on the end face of the reinforcement plate body 100 away from the protrusion structure 101, and at least a portion of the support plate 400 is projected onto the reinforcement plate body 100 within the outline of the protrusion structure 101 and is configured to support the outer hood plate 300.
[0032] It should be noted that when closing the machine cover, the operator will generally apply pressure to the part of the outer panel 300 of the machine cover that faces the protruding structure 101 (hereinafter referred to as the locking area for ease of description). Since the protruding structure 101 itself is recessed along the thickness direction, the reinforcing plate body 100 will form a "cavity" in the recessed position and will not be able to directly support the outer panel 300 of the machine cover. The concentrated load generated by the operator pressing the locking area when closing the machine cover will lose continuous support. Over time, this will easily cause local permanent dents in the outer panel.
[0033] To address the aforementioned issues, the hood reinforcement plate structure in this embodiment further includes a support plate 400. The number of support plates 400 can be one, two, three, or four, etc., without specific limitations, and depends on actual needs. Figure 2 As shown, two support plates 400 are installed on the upper end face of the reinforcing plate body 100, and the projection of the middle part of a single support plate 400 on the reinforcing plate body 100 is within the outline range of the protruding structure 101; when the hood reinforcing plate structure is assembled, the two support plates 400 can be used to support the outer plate 300 of the hood.
[0034] In this embodiment, when there is one support plate 400, the support plate 400 preferably spans the cavity opening 105 formed by the protruding structure 101; when there are two support plates 400, the two support plates 400 are preferably arranged diagonally, with the following effect: Figure 2As shown; when there are three or more support plates 400, the multiple support plates 400 are preferably evenly distributed along the cavity opening 105 formed by the protruding structure 101.
[0035] In this optional embodiment, a support plate 400 supporting the outer panel 300 of the machine cover is installed on the end face of the reinforcing plate body 100 away from the protrusion structure 101, and its projection on the reinforcing plate body 100 is located within the outline range of the protrusion structure 101. This is equivalent to rebuilding a "bridge" at the cavity opening 105 formed by the protrusion structure 101. When the operator presses the locking area of the outer panel 300 of the machine cover, the concentrated load is first transmitted to the support plate 400, and then the support plate 400 transmits the force to the reinforcing plate body 100, and then evenly transmits it to the inner panel 200 of the machine cover through the reinforcing plate body 100, so that the outer panel 300 of the machine cover can obtain continuous and stable elastic support, and no indentation or deformation will occur even after long-term use.
[0036] Optionally, the reinforcing plate body 100 is provided with a through first weight-reducing hole 103 along the thickness direction; the support plate 400 is configured to be formed by stamping the sheet material within the first weight-reducing hole 103.
[0037] In this embodiment, the reinforcing plate body 100 is typically punched with first weight-reducing holes 103 simultaneously during the stamping process to meet lightweight requirements; while the support plate 400 is formed by stamping the sheet material within the first weight-reducing holes 103. It can be integrally stamped with the reinforcing plate body 100 during production and then separated from the first weight-reducing holes 103; alternatively, it can be formed from sheet material cut out from the first weight-reducing holes 103. The number of first weight-reducing holes 103 and the number of support plates 400 that can be made from the sheet material within the first weight-reducing holes 103 are not specifically limited and are determined according to actual needs. Figure 3 As shown, a first weight-reducing hole 103 is provided at each of the left and right ends of the reinforcing plate body 100, and the plate material in a single first weight-reducing hole 103 can be stamped to form a support plate 400.
[0038] In this optional embodiment, the support plate 400 is formed by stamping the sheet metal in the first weight reduction hole 103, which reduces the generation of waste material and eliminates the need for additional material preparation and separate processing of the support plate 400, thereby simultaneously improving material utilization and saving time.
[0039] Meanwhile, after welding the support plate 400 to the preset position of the reinforcing plate body 100, the finished product processing of the hood reinforcing plate structure can be realized.
[0040] It should be noted that although the preferred embodiment described above is the support plate 400 being formed by stamping the sheet metal within the first weight reduction hole 103, the possibility of the support plate 400 being prepared and formed independently is not excluded.
[0041] Optionally, the support plate 400 includes a first plate member 401, a second plate member 402, and a third plate member 403. Both the first plate member 401 and the third plate member 403 are bent plates. One end of the first plate member 401 and one end of the third plate member 403 are both connected to the reinforcing plate body 100. The other end of the first plate member 401 and the other end of the third plate member 403 are bent and extended and respectively connected to opposite ends of the second plate member 402. The second plate member 402 is configured to support the outer hood panel 300.
[0042] Specifically, as Figure 4 shown, the support plate 400 is generally in the shape of a "ji" character. It includes an integrally formed first plate member 401, a second plate member 402, and a third plate member 403. Among them, both the first plate member 401 and the third plate member 403 are L-shaped plates, and the second plate member 402 is a straight plate. The L-shaped long sides of the first plate member 401 and the L-shaped long sides of the third plate member 403 are respectively fitted and welded to the reinforcing plate body 100. The L-shaped short side of the first plate member 401 is angularly connected to one end of the second plate member 402, and the L-shaped short side of the third plate member 403 is also angularly connected to the other end of the second plate member 402, so that the three form a continuous arched cross-section. Among them, the second plate member 402 can be fitted with the outer hood panel 300 to support the outer hood panel 300.
[0043] In this optional embodiment, since the first plate member 401 and the third plate member 403 are first fixedly connected to the reinforcing plate body 100, then bent towards each other and respectively connected to both ends of the second plate member 402, the three form a closed "bow-shaped" force-bearing frame in the same plane: when the outer hood panel 300 is受压, the load is first transmitted to the second plate member 402, and then two symmetric force flow paths are formed through the bent sections of the first plate member 401 and the third plate member 403 and quickly spread to the reinforcing plate body 100. The flange moment of inertia possessed by the bent plate significantly improves the local bending stiffness without additional thickening, enabling the outer hood panel 300 to be continuously and stably supported and preventing the outer hood panel 300 from denting in the locking area. At the same time, the "bow-shaped" structure reserves a buffer cavity in the vertical direction to absorb impact energy.
[0044] Optionally, an installation groove 106 is provided at the edge of the end face of the reinforcing plate body 100 away from the convex structure 101. The first plate member 401 and the third plate member 403 are arranged in the corresponding installation grooves 106, and the projection of the second plate member 402 on the reinforcing plate body 100 is within the contour range of the convex structure 101.
[0045] Specifically, as Figure 2As shown, the end face of the reinforcing plate body 100 away from the protrusion structure 101 is provided with a plurality of mounting grooves 106 at the edge of the protrusion structure 101. In the structure of a single support plate 400, the second plate 402 and the third plate 403 each correspond to a mounting groove 106, that is, the second plate 402 and the third plate 403 are respectively accommodated in the corresponding mounting groove 106. At the same time, the projection of the second plate 402 on the reinforcing plate body 100 is located within the outline range of the protrusion structure 101, and supports the outer panel 300 of the hood when it is in contact with the outer panel 300 of the hood.
[0046] In this optional embodiment, when installing the support plate 400, the mounting groove 106 can not only enable the first plate 401 or the third plate 403 to be quickly positioned, but also effectively reduce the protrusion height of the second plate 402 relative to the reinforcing plate body 100, so as to avoid obstructing the installation of the outer panel 300 of the machine cover.
[0047] Optionally, a reinforcing structure 404 is provided at the bend of the first plate 401 and the bend of the third plate 403; the reinforcing structure 404 includes at least one of a protrusion, a reinforcing plate, or a reinforcing rib.
[0048] Specifically, both the first plate 401 and the third plate 403 are L-shaped plates, and each has a reinforcing structure 404 at its bend. The number of reinforcing structures 404 is not limited and depends on actual needs; the shape of the reinforcing structure 404 can be a protrusion, a reinforcing plate, or a reinforcing rib. Figure 4 As shown, the first plate 401 and the third plate 403 are respectively provided with two convex-shaped reinforcing structures 404 at the bends.
[0049] In this optional embodiment, since the bending points of the first plate 401 and the third plate 403 become stress concentration areas when subjected to force, this embodiment adds at least one of the following: a bulge, a reinforcing plate, or a reinforcing rib. The bulge increases the thickness of the cross-section plate and the moment of inertia through local shaping, which significantly enhances the bending resistance of the bending area. The reinforcing plate or reinforcing rib forms a secondary force transmission path, which quickly disperses the peak stress to the adjacent plane. The three can be used individually or in combination, which can significantly reduce the risk of plastic deformation at the bending point without increasing the overall plate thickness and weight, and ensure that the support plate 400 maintains stable load-bearing stiffness during long-term use.
[0050] Optionally, the second plate 402 has a second adhesive groove structure 405 on its end face away from the protrusion structure 101.
[0051] Specifically, the second plate 402 has a second glue groove structure 405 on the end face opposite to the protruding structure 101 (that is, the end face of the second plate 402 facing the outer panel 300 of the casing). The number of second glue groove structures 405 is not specifically limited and depends on actual needs; the shape of the second glue groove structure 405 can be elongated, rectangular, or circular, etc. Figure 4 As shown, the second plate 402 has a long strip-shaped second glue groove structure 405 on the end face opposite to the protrusion structure 101.
[0052] In this optional embodiment, since the end face of the second plate 402 facing away from the protruding structure 101 directly faces the outer panel 300 of the hood, and the end face is connected to the outer panel 300 of the hood by an expanding adhesive, after the second adhesive groove structure 405 is punched out on the end face, the expanding adhesive can be constrained within the second adhesive groove structure 405: this can prevent the adhesive from overflowing and causing waste and pollution, and can also ensure that the adhesive layer thickness is uniform, so that the outer panel 300 of the hood can obtain continuous and stable elastic support; at the same time, the bottom plane of the groove and the adhesive layer form a larger bonding area, which improves the shear strength, and the anti-dent and vibration reduction performance of the outer panel 300 of the hood is improved simultaneously.
[0053] Furthermore, the second adhesive groove structure 405 is formed by a recess in a portion of the second plate 402 along the thickness direction of the second plate 402. Thus, in addition to accommodating the expanding adhesive, the second adhesive groove structure 405 can also enhance the strength of the second plate 402 at this location.
[0054] Optionally, the second plate 402 is provided with a through second weight-reducing hole 406 along the thickness direction.
[0055] Specifically, during the stamping process, the second plate 402 is typically punched with second weight-reducing holes 406 simultaneously. The number of these holes is not limited and depends on actual requirements. For example... Figure 4 As shown, a second weight-reduction hole 406 is provided at the part of the second plate 402 adjacent to the second glue groove, so as to meet the weight reduction requirements of the support plate 400.
[0056] Optionally, the reinforcing plate body 100 is provided with a plurality of support feet 104 on its periphery, and the reinforcing plate body 100 is configured to be connected to the inner panel 200 of the hood via the plurality of support feet 104.
[0057] Specifically, such as Figure 1 As shown, multiple support feet 104 are distributed around the periphery of the reinforcing plate body 100. The number of support feet 104 is not specifically limited and depends on actual needs. The reinforcing plate body 100 can also be welded and fixed to the inner plate 200 of the machine cover through the support feet 104.
[0058] In this optional embodiment, since multiple support legs 104 are integrally stamped on the periphery of the reinforcing plate body 100, these support legs 104 form discrete multi-point connections when connected to the inner hood panel 200. This multi-point layout creates a truss-like constraint system between the reinforcing plate body 100 and the inner hood panel 200: when any support leg 104 experiences slight displacement in the lateral or longitudinal direction, the remaining support points can provide a counter-torque, significantly suppressing in-plane rotation and out-of-plane warping. This ensures that the reinforcing plate body 100 and the inner hood panel 200 are securely fixed and will not loosen even after long-term use. The connection between the reinforcing plate body 100 and the inner hood panel 200 via the multiple support legs 104 on its periphery, combined with the connection between the central protruding structure 101 and the inner hood panel 200, further enhances the stability of the fixation between the reinforcing plate body 100 and the inner hood panel 200.
[0059] An embodiment of this utility model provides a machine cover, including an outer cover panel 300, an inner cover panel 200, and a machine cover reinforcing plate structure as described above.
[0060] Specifically, such as Figure 5 , 6 As shown, the hood reinforcement plate structure is located between the outer hood plate 300 and the inner hood plate 200. The reinforcement plate body 100 is welded to the inner hood plate 200 and supports the outer hood plate 300. The protruding structure 101 is located in the recess 201 of the inner hood plate 200 and is welded and fixed to the inner hood plate 200.
