It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.
The engine cover mainly comprises an engine cover outer plate 10 and an engine cover inner plate 20, wherein an engine cover outer plate support bracket (hereinafter referred to as an outer plate support bracket 40) is fixedly arranged on the engine cover inner plate 20 in a spot welding mode and positioned at the left side and the right side of the engine cover inner plate 20, and the left and the right outer plate support brackets 40 are symmetrically arranged, for example, an example that the outer plate support bracket 40 is arranged at the right side of the engine cover inner plate 20 is given in fig. 4; after the outer cover plate 10 and the inner cover plate 20 are assembled by adopting the edge covering process, the outer plate support bracket 40 is clamped between the outer cover plate 10 and the inner cover plate 20. In addition, for the left outer panel support bracket 40, the left fender is positioned at the left lower side of the left outer panel support bracket 40, and for the right outer panel support bracket 40, the right fender is positioned at the right lower side of the right outer panel support bracket 40.
Referring to fig. 1, 3 and 4, an embodiment of the present invention provides an outer panel support bracket (hereinafter referred to as an outer panel support bracket 40) for an engine cover, which includes a support portion 42 and at least two connection portions 41, wherein the connection portions 41 are used for connecting with side edges of an inner panel 20 for the engine cover, the support portion 42 is used for supporting the side edges of an outer panel 10 for the engine cover, two ends of each connection portion 41 are respectively connected with one support portion 42, and adjacent connection portions 41 are connected through the support portion 42.
Specifically, the outer panel support bracket 40 is typically a sheet metal member, and after stamping, it forms alternately connected connection portions 41 and support portions 42, so that the outer panel support bracket 40 is approximately in a wave shape, where the connection portions 41 form wave troughs, are typically used for being connected with the side edges of the hood inner panel 20 by spot welding, the support portions 42 form wave crests, are used for supporting the side edges of the hood outer panel 10, and two ends of each connection portion 41 are respectively connected with one support portion 42, so that the outer panel support bracket 40 includes at least two connection portions 41 and at least three support portions 42, that is, at least two connection points that can be connected by spot welding are formed between the outer panel support bracket 40 and the hood inner panel 20, and at least three support points are formed between the outer panel support bracket and the hood outer panel 10. The lateral widths of the engine covers may be different for different types of engine covers, and thus the areas to be supported may be different, and at this time, the number of the connection portions 41 or the support portions 42 may be set as needed to change the length of the outer panel support bracket 40 so as to match the areas to be supported on the engine covers of different types.
In this embodiment, the outer plate support bracket 40 is added at the position of the area where the rigidity of the side edge of the engine cover is weak to support the side edge of the engine cover, the leaning strength and the deformation resistance of the side edge of the engine cover are improved by utilizing the outer plate support bracket 40, the concave resistance effect is obvious, the cost is low, and the lightweight design of the engine cover is realized by optimizing the structure of the outer plate support bracket 40. Meanwhile, the outer plate support bracket 40 is provided with the connecting parts 41 and the supporting parts 42 which are alternately connected, and two ends of each connecting part 41 of at least two connecting parts 41 are respectively connected with one supporting part 42, so that at least two connecting points which can be connected by spot welding are formed between the outer plate support bracket 40 and the inner plate 20 of the machine cover, and at least three supporting points are formed between the outer plate support bracket and the outer plate 10 of the machine cover, thus the connecting area between the outer plate support bracket 40 and the inner plate 20 of the machine cover and the supporting area between the outer plate 10 of the machine cover can be increased, and the outer plate 10 of the machine cover with larger coverage and wider side edge can be better supported.
Alternatively, the connecting portion 41 is used for connecting with the hood inner panel 20 by spot welding.
Specifically, the connecting portion 41 and the cover inner panel 20 may be connected by spot welding or by adhesion. In the assembly process of the engine cover, since the outer panel support bracket 40 is generally mounted to the cover inner panel 20, the outer panel support bracket 40 and the cover inner panel 20 form a cover inner panel assembly, and then the cover inner panel assembly and the cover outer panel 10 are assembled. And when the adhesive is adopted for bonding, the adhesive needs to be cured, and the assembly beat is easily influenced.
In the present embodiment, therefore, the assembling efficiency is improved by using the connection portion 41 for spot welding with the cover inner panel 20, and the process is simple and convenient.
Further, the respective connection portions 41 are not on the same horizontal plane.
Since the convex hull structure is generally disposed at the mounting position of the inner cover plate 20 for mounting the outer plate support bracket 40, the mounting surface of the outer plate support bracket 40 is rough, so that in this embodiment, the connecting portions 41 of the outer plate support bracket 40 are not on the same horizontal plane to adapt to the inner cover plate 20, so that the connecting portions 41 of the outer plate support bracket 40 can be attached to the inner cover plate 20, and the outer plate support bracket 40 is conveniently fixed on the inner cover plate 20 by spot welding.
Alternatively, as shown in connection with fig. 2, the orthographic projections of the supporting portion 42 and the connecting portion 41 on the same horizontal plane are on the same straight line. Wherein the horizontal plane is a plane parallel to the XY plane in fig. 1.
Specifically, the orthographic projection of the support portion 42 and the connection portion 41 on the same horizontal plane being on the same line means that after the outer panel support bracket 40 is unfolded and laid out, the support portion 42 and the connection portion 41 are on the same line, and at this time, the outer panel support bracket 40 is in a long rectangular plate structure as a whole, as shown in fig. 2.
In this way, when the developed length and the pressing depth are the same, the length of the outer panel support bracket 40 formed after the pressing process is longest when the orthographic projections of the support portion 42 and the connecting portion 41 on the same horizontal plane are on the same straight line, so that the support range of the outer panel support bracket 40 to the hood outer panel 10 is wider.
Alternatively, as shown in conjunction with fig. 1, the support portion 42 includes a first support portion 421 and a second support portion 422, both ends of the first support portion 421 are respectively connected to the two connection portions 41, the second support portion 422 constitutes both ends in the length direction of the outer panel support bracket 40, and one end of the second support portion 422 is connected to the connection portion 41, and the other end is for abutting against the hood outer panel 10. The length direction of the outer plate support bracket 40 is referred to as the Y-axis direction in fig. 1, and the width direction of the outer plate support bracket 40 is referred to as the X-axis direction in fig. 1.
Specifically, the first supporting portion 421 is located at the middle portion of the outer panel support bracket 40, and both ends thereof are respectively connected to one connecting portion 41, thus having high supporting rigidity, while the second supporting portion 422 constitutes both ends in the length direction of the outer panel support bracket 40, i.e., both front and rear ends of the outer panel support bracket 40, and one end of the second supporting portion 422 is connected to the connecting portion 41, and the other end is adapted to abut against the hood outer panel 10, such that only one end of the second supporting portion 422 is connected to the connecting portion 41, while the other end is in a free state, and the supporting rigidity is weak.
In this embodiment, the two ends of the first supporting portion 421 are respectively connected to the two connecting portions 41, so that the middle portion of the outer panel support bracket 40 has a high supporting rigidity, and the second supporting portion 422 forming the two ends of the outer panel support bracket 40 in the length direction is provided with one end connected to the connecting portion 41, and the other end is used for abutting against the hood outer panel 10, so that the rigidity of the two ends of the outer panel support bracket 40 is slightly lower, and thus the outer panel support bracket 40 can have a high supporting rigidity under a small load, and can easily flex under a large load, and the rigidity is rapidly reduced, thereby meeting the relevant requirements of the pedestrian protection law.
Alternatively, as shown in conjunction with fig. 1, the first support portion 421 extends away from the connecting portion 41 at one end thereof in a direction away from the connecting portion 41 and in a direction toward the hood outer panel 10, and the second support portion 422 forms an obtuse angle with the connecting portion 41 at each of the two ends thereof in the longitudinal direction of the outer panel support bracket 40.
Specifically, for convenience of description, the first support portion 421 constituting the front end of the outer panel support bracket 40 is described herein as an example, the rear end of the first support portion 421 is connected to the front end of the connection portion 41, and the front end of the first support portion 421 extends upward while also extending forward so that the front end of the first support portion 421 is far from the connection portion 41, thereby forming an obtuse angle with the connection portion 41, and the front end of the second support portion 422 forms an obtuse angle with the connection portion 41, and the rear end of the second support portion 422 also forms an obtuse angle with the connection portion 41, so that the outer panel support bracket 40 as a whole has a substantially "W" shaped structure or a "W" shaped structure, wherein, it is to be noted that when the connection portion 41 is provided in three or more, the outer panel support bracket 40 as a whole has a plurality of "V" shaped structures connected in sequence, which may be regarded as a "W" shaped structure.
In this embodiment, the outer plate support bracket 40 is configured in a "W" shape or a "W" like structure, so that the two ends of the outer plate support bracket 40 have support rigidity under small load impact, and can flex under large load impact to weaken the rigidity, thereby ensuring that the outer plate support bracket 40 has sufficient support rigidity and meets the pedestrian protection requirement.
Optionally, as shown in fig. 1, the first support portion 421 is provided with a first glue groove 423 extending in the length direction of the outer panel support bracket 40, and/or the second support portion 422 is provided with a second glue groove 424 extending in the width direction of the outer panel support bracket 40.
Specifically, the first glue groove 423 is generally disposed on a first support segment 4212 (described below) of the first support 421, and the second glue groove 424 is generally disposed on a second support segment 4222 (described below) of the second support 422. Since the first support 421 is located at the middle of the outer panel support bracket 40, the first support segment 4212 is generally designed to be longer, and the second support 422 is located at both ends of the outer panel support bracket 40, and the second support segment 4222 is generally designed to be shorter. Based on this, the first glue groove 423 is provided on the first support 421 in the front-rear direction and/or the second glue groove 424 is provided on the second support 422 in the left-right direction in the present embodiment.
In this embodiment, the first glue groove 423 is formed at the portion of the first supporting portion 421 for abutting against the outer cover plate 10, and the first glue groove 423 is filled with the expansion glue, and/or the second glue groove 424 is formed at the portion of the second supporting portion 422 for abutting against the outer cover plate 10, and the expansion glue is filled in the second glue groove 424, so that after the outer cover plate 10 and the inner cover plate 20 are assembled, the supporting portion 42 and the outer cover plate 10 form adhesion, so that the stability of the supporting portion 42 when supporting the outer cover plate 10 is improved, the leaning strength and the deformation resistance of the side edge of the engine cover are improved, and meanwhile, the noise and vibration of the engine cover at the mounting area of the outer cover supporting bracket 40 can be reduced by adopting an adhesion mode between the supporting portion 42 and the outer cover plate 10.
Alternatively, as shown in connection with fig. 1, the ratio of the width of the outer panel support bracket 40 to the groove width of the first adhesive groove 423 or the second adhesive groove 424 is between 2 and 6.
Specifically, since the outer panel support bracket 40 extends in the front-rear direction (i.e., the Y-axis direction in fig. 1), the width of the outer panel support bracket 40 refers to the dimension of the outer panel support bracket 40 in the X-axis direction in fig. 1, the extending direction of the first glue groove 423 is the same as the outer panel support bracket 40, the groove width of the first glue groove 423 refers to the dimension of the first glue groove 423 in the X-axis direction in fig. 1, and the groove width of the second glue groove 424 extends in the left-right direction (i.e., the X-axis direction in fig. 1), and the groove width of the second glue groove 424 refers to the dimension of the second glue groove 424 in the Y-axis direction in fig. 1. In the case of designing the outer panel support bracket 40 to be lightweight, the groove widths of the first and second glue grooves 423 and 424 are generally set to be the same and set to be a fixed value, and the width of the outer panel support bracket 40 is set to be a variable value, and if the width of the outer panel support bracket 40 is designed to be too large, the weight of the outer panel support bracket 40 is increased, which is disadvantageous in the lightweight design, and if the width of the outer panel support bracket 40 is designed to be too small, the support rigidity of the support portion 42 is reduced.
In the present embodiment, by comprehensively considering the support rigidity and the lightweight design of the outer panel support bracket 40, the outer panel support bracket 40 is balanced in both the support rigidity and the lightweight design by setting the width of the outer panel support bracket 40 to 2 to 6 times the groove width of the first glue groove 423 or the second glue groove 424.
Further, when the outer panel support bracket 40 has a "W" shape structure, that is, the number of the connection portions 41 is two, it is preferable that the width of the outer panel support bracket 40 is twice the groove width of the first adhesive groove 423 or the second adhesive groove 424. When the number of the connection portions 41 is three or more, the width of the outer panel support bracket 40 may be set to be twice or more the groove width of the first adhesive groove 423 or the second adhesive groove 424.
Alternatively, as shown in fig. 1, the first supporting portion 421 includes a first abutting section 4211 and a first supporting section 4212, the first supporting section 4212 forms an obtuse angle with the connecting portion 41, the first abutting section 4211 is used for abutting against the outer cover plate 10, the first supporting section 4212 is disposed at two ends of the first abutting section 4211, and two ends of the first supporting section 4212 are respectively connected with the first abutting section 4211 and the connecting portion 41.
Specifically, the first supporting section 4212 and the connecting portion 41 are generally in a flat plate structure, and an included angle between the two is an obtuse angle, so that the whole first supporting portion 421 is generally in a trapezoid structure with a narrow upper end and a wide lower end and an open lower end. The two first supporting sections 4212 form two oblique sides of the trapezoid structure, the first abutting section 4211 forms an upper bottom of the trapezoid structure (a lower bottom of the trapezoid structure is open), the two first supporting sections 4212 are respectively connected with the one connecting portion 41, and the first glue groove 423 is disposed on the first abutting section 4211.
In this embodiment, the first supporting portion 421 is provided to include the first abutting section 4211 and the first supporting section 4212, and the first supporting section 4212 is provided at both ends of the first abutting section 4211, so that the whole first supporting portion 421 has a trapezoid structure with a narrow upper end, a wide lower end and an open lower end, which is simple in structure and easy to manufacture, and can ensure that the first supporting portion 421 and the cover outer plate 10 form surface-to-surface contact at the first supporting section 4212, thereby better supporting the side edge of the cover outer plate 10.
Alternatively, as shown in conjunction with fig. 1, the second supporting portion 422 includes a second abutting section 4221 and a second supporting section 4222, the second abutting section 4221 is for abutting against the cover outer plate 10, and the second abutting section 4221, the second supporting section 4222 and the connecting portion 41 are sequentially connected.
Specifically, the second supporting portion 422 is integrally formed as a cantilever structure, for example, the second supporting portion 422 forming the front end of the outer plate supporting bracket 40 is formed by extending the front end of the connecting portion 41 obliquely upward for a certain distance to form the second supporting section 4222, and then extending horizontally forward to form the second abutting section 4221, so as to form the cantilever structure of the second supporting portion 422, and the second glue groove 424 is disposed on the second abutting section 4221.
In the present embodiment, by providing the second support portion 422 as a cantilever structure including the second abutment section 4221 and the second support section 4222, and supporting the cover outer panel 10 by abutment of the second abutment section 4221 with the cover outer panel 10, the second support portion 422 and the cover outer panel 10 are brought into surface-to-surface contact with each other, the contact area therebetween is increased, and thus the supporting effect is better provided.
Further, the angle between the second support section 4222 and the connection portion 41 is an obtuse angle.
Specifically, when the outer panel support bracket 40 is structurally optimized, the stiffness properties of the two ends of the outer panel support bracket 40 can be adjusted according to the included angle between the second support section 4222 and the connecting portion 41, that is, if the stiffness of the two ends of the outer panel support bracket 40 needs to be weakened, the included angle between the second support section 4222 and the connecting portion 41 can be designed to be larger, for example, an obtuse angle, and if the stiffness of the two ends of the outer panel support bracket 40 needs to be improved, the included angle between the second support section 4222 and the connecting portion 41 can be designed to be smaller, for example, a right angle. In practice, the angle between the second support segments 4222 and the connection 41 may be varied by adjusting the draft angle of the outer plate support bracket 40 at the second support portion 422.
In the present embodiment, the included angle between the second support section 4222 and the connecting portion 41 is set to be an obtuse angle, so that the outer panel support bracket 40 has both sufficient support rigidity and satisfies the pedestrian protection requirement.
Optionally, as shown in connection with fig. 1, the first support section 4212 is provided with a lightening hole 427.
Specifically, the lightening holes 427 may be holes with geometric shapes such as kidney-shaped holes, circular holes, oval holes or polygonal holes, which are not particularly limited herein, in practical applications, it is generally preferable to set the lightening holes 427 as kidney-shaped holes, and the size of the kidney-shaped holes may be adjusted according to the pedestrian protection condition, for example, if the pedestrian protection score of the engine cover at the outer panel support bracket 40 needs to be increased, the support rigidity of the area needs to be reduced, and at this time, the support rigidity of the outer panel support bracket 40 may be weakened by increasing the lightening holes 427 and extending the same to the bending position near the first glue groove 423.
In the present embodiment, the weight-reducing holes 427 are provided in the first support sections 4212 to reduce the weight of the outer panel support bracket 40 while ensuring the support rigidity of the outer panel support bracket 40, thereby realizing a lightweight design of the outer panel support bracket 40.
Optionally, as shown in connection with fig. 1, a first reinforcing rib 425 is provided at the connection between the second support segment 4222 and the connection portion 41, and/or a second reinforcing rib 426 is provided at the connection between the second abutment segment 4221 and the second support segment 4222.
In this embodiment, the connection between the second support segment 4222 and the connection portion 41 forms the first reinforcing rib 425 by stamping, and/or the connection between the second abutment segment 4221 and the second support segment 4222 forms the second reinforcing rib 426 by stamping.
