The second hinge portion is connected to the front cover. A fender, the rear end of which is connected to the bending structure, the bending structure and the first hinge portion being arranged at least in the height direction to form a first energy-absorbing cavity between them.

[0007] In some embodiments, the first hinge portion includes a fixed portion and an extension arm. The fixed portion is fixed to the fender side panel, and the hinge bracket is fixed to the fixed portion. The extension arm extends obliquely upward from the fixed portion in the negative X direction of the vehicle to form a cantilever structure. The end of the extension arm away from the fixed portion is hinged to the second hinge portion. In some implementations, the vehicle front hood system includes a side panel reinforcement connected to the fender side panel, a first hinge portion located in front of the side panel reinforcement, and the first hinge portion and the side panel reinforcement enclosing a hollow channel for wire harnesses to pass through; or, the extension arm has a hollow area for wire harnesses to pass through.
[0008] In some implementations, the vehicle front hood system includes a side panel reinforcement connected to the fender side panel, the side panel reinforcement and the extension arm being spaced apart from each other and maintaining a preset gap between them.
[0009] In some embodiments, the hinge bracket includes a fixed mating part and a bending part; the fixed mating part abuts against and is fixed to the outer side of the first hinge part in the Y direction of the vehicle, and the bending part connects the fixed mating part and the bending structure; the bending part extends from the top edge of the fixed mating part in a direction away from the fixed mating part, and the top edge of the bending part is higher than the top edge of the fixed mating part, and the bending structure extends from the top edge of the bending part inward in the Y direction of the vehicle and beyond the first hinge part.

[0018] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.
[0019] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0020] In the following description, the vehicle's forward and backward direction is the X-axis, with the forward direction being the positive X-axis and the backward direction being the negative X-axis. The vehicle's left and right direction is the Y-axis. The vehicle's up and down direction is the Z-axis, also known as the height direction.
[0021] When a pedestrian collides with a vehicle, the pedestrian's head is likely to strike the vehicle's hood, causing injury, especially in the hood hinge collision area. This area has limited space and contains hinges and struts, which are high-rigidity structures used for support, making it particularly vulnerable to injury. Therefore, designing a vehicle hood system to reduce pedestrian head injuries during collisions, and improving the safety performance of the vehicle hood system, while considering the limited space in the hood hinge collision area and without reducing the rigidity of the hinges and struts, has become a pressing technical problem in this field.
[0022] Therefore, this application provides a vehicle front hood system. Please refer to [link / reference]. Figure 1 and Figure 2 It includes the front cover 1, strut 2, fender side sealing plate 3, hinge 4, and fender 5.
[0023] One end of the strut 2 is connected to the front cover 1.
[0024] Please see Figure 5 The hinge 4 includes a hinge bracket 41, a first hinge portion 42 and a second hinge portion 43 that are hinged to each other. The first hinge portion 42 is fixed to the fender side sealing plate 3. The end of the strut 2 away from the front cover 1 is hinged to the first hinge portion 42. The bottom end of the hinge bracket 41 is fixed to the first hinge portion 42. A part of the hinge bracket 41 bends inward in the Y direction of the vehicle to form a bending structure 411. The second hinge portion 43 is connected to the front cover 1.
[0025] The fender side panel 3 provides mounting support for the hinge 4.
[0026] The rear end of the fender 5 is connected to the bending structure 411, and the bending structure 411 and the first hinge portion 42 are arranged at least in the height direction to form a first energy-absorbing cavity A between them.
[0027] The front cover 1 can also be referred to as the engine hood. The strut 2 is telescopic, which can open or close the front cover 1. The specific structure of the strut 2 is not limited, for example, it can be a gas spring, an electric strut, a hydraulic strut, etc., and there is no limitation here.
[0028] The first hinge portion 42 can be referred to as the female hinge, and the second hinge portion 43 can be referred to as the male hinge. Since the front cover 1 is connected to the second hinge portion 43, when the support rod 2 is extending or retracting, the front cover 1 rotates relative to the first hinge portion 42 around the hinge point through the second hinge portion 43, thereby allowing the front cover 1 to open or close.
[0029] The way the bottom end of the hinge bracket 41 is fixed to the first hinge part 42 is not limited, as long as there is no relative movement between the two. For example, the hinge bracket 41 and the first hinge part 42 can be welded, connected by screws, riveted, etc.
[0030] The inward bending of a portion of the aforementioned hinge bracket 41 in the Y direction of the vehicle refers to the direction in the Y direction and toward the vertical plane of the vehicle. For example, for the hinge bracket 41 on the right side of the vehicle, bending in the Y direction of the vehicle means bending to the left, and for the hinge bracket 41 on the left side of the vehicle, bending in the Y direction of the vehicle means bending to the right.
[0031] In this embodiment of the vehicle front hood system, the hinge 4 is positioned relatively far back in the X-direction of the vehicle, for example, as close as possible to the A-pillar. During the opening and closing of the front hood 1, the second hinge portion 43 drives the front hood 1 to rotate around the hinge point (the hinge point of the first hinge portion 42 and the second hinge portion 43). Since one end of the support rod 2 is hinged to the first hinge portion 42, the installation position of the support rod 2 is relatively far back. This means that the installation position of the support rod 2 does not occupy the space on the front side of the vehicle, which is beneficial for optimizing the layout of components. In addition, since the first hinge portion 42 itself has high structural strength and rigidity, using the first hinge portion 42 to install the support rod 2 can meet the structural strength requirements for the support rod 2, and there is no need to design an additional mounting bracket for the support rod 2. This not only helps to reduce the number of components and save assembly steps, but also helps to reduce the structure and contact hard points in the front hood hinge collision area E (because: if a mounting bracket is added, the mounting bracket itself must have high structural strength to meet the support requirements for the support rod 2, and at this time the mounting bracket will add an extra contact hard point).
[0032] Since the fender 5 is mounted on the hinge bracket 41, and the hinge bracket 41 includes a bending structure 411, which has the ability to absorb energy through deformation, the bending structure 411 and the first hinge part 42 are arranged at intervals in the height direction to form a first energy-absorbing cavity A. When the vehicle hood system collides with a pedestrian, the hood 1 and / or the fender 5 transmit the collision force to the bending structure 411 of the hinge bracket 41. The design of the first energy-absorbing cavity A facilitates the downward deformation of the bending structure 411 after being subjected to force, thereby absorbing the collision energy. Furthermore, the first energy-absorbing cavity A acts as a buffer area between the pedestrian and the first hinge part 42 and the strut 2, reducing the injury to the pedestrian's head during the collision and improving the safety performance of the vehicle hood system. In other words, within a limited arrangement space, without reducing the structural strength and stiffness of the hinge 4, the injury value to the human head during a pedestrian collision can be reduced.
[0033] In some embodiments, please refer to Figure 3 A portion of the fender side panel 3 is bent inward toward the vehicle in the Y direction to form a horizontal panel 31; the vehicle front cover system includes a hinge trim 6, the rear end of the hinge trim 6 is fixed to the hinge bracket 41 and forms a first mounting position 62, the front end of the hinge trim 6 is fixed to the horizontal panel 31 and forms a second mounting position 63, and the bottom edge of the portion of the hinge trim 6 between the first mounting position 62 and the second mounting position 63 is spaced apart from the horizontal panel 31 in the height direction and forms a second energy-absorbing cavity B.
[0034] The hinge trim 6 is positioned above the horizontal plate portion 31. When the front cover 1 is closed, the support rod 2 is located on one side of the hinge trim 6 in the Y-direction of the vehicle, and the first hinge portion 42 and the hinge bracket 41 are located on the other side of the hinge trim 6 in the Y-direction of the vehicle. The hinge trim 6 is used to conceal the first hinge portion 42 and the hinge bracket 41, as well as the connection position between the first hinge portion 42 and the support rod 2, and the connection position between the hinge bracket 41 and the fender 5. When the user opens the front cover 1, the user can barely see the first hinge portion 42 and the hinge bracket 41. The hinge trim 6 is positioned along the X-direction of the vehicle, and the first mounting position 62 and the second mounting position 63 respectively fix the front and rear ends of the hinge trim 6, reducing vibration and abnormal noise of the hinge trim 6 during vehicle operation.
[0035] To enhance the fixing effect, the second mounting position 63 may have one or more mounting points arranged along the X direction of the hinge trim 6. The mounting points of the second mounting position 63 cannot be located directly below the front hood hinge collision area E. The first mounting position 62 should be as far away as possible from the front hood hinge collision area E. When the second mounting position 63 has multiple mounting points, the position of the second energy-absorbing cavity B is the gap below the area between the first mounting position 62 and the mounting point closest to the first mounting position 62.
[0036] In this embodiment, based on the already integrated installation of the strut 2 and fender 5 on the hinge 4, the hinge trim 6 is further installed on the hinge bracket 41 to improve the integration. The fender 5 and the hinge trim 6 share the hinge bracket 41 as the mounting bracket, eliminating the need to design an additional mounting bracket for the hinge trim 6. This not only helps reduce the number of parts and saves assembly steps, but also helps reduce the structure within the front hood hinge collision area E. Although the hinge trim 6 and the hinge bracket 41 form an unavoidable contact hard point at the first installation position 62, this contact hard point is located above the first energy-absorbing cavity A, which can reduce the injury value to the human head in the event of a pedestrian collision.
[0037] Furthermore, when the vehicle front hood system collides with a pedestrian, the front hood 1 transmits the collision force to the hinge trim 6. The design of the second energy-absorbing cavity B facilitates the downward deformation of the hinge trim 6 under force, thereby absorbing the collision energy. Since the second mounting position 63 is not within the front hood hinge collision area E, there are no contact hard points between the hinge trim 6 and the horizontal plate portion 31 within the front hood hinge collision area E, which can further reduce the injury to the pedestrian during the collision and improve the safety performance of the vehicle front hood system.
[0038] For example, the hinge 4 includes a shaft portion 4211, one end of which is fixed to a first hinge portion 42. The shaft portion 4211 extends along the Y direction of the vehicle towards the side of the strut 2. The hinge trim 6 has a hole 61 through which the shaft portion 4211 passes, thereby passing through the hinge trim 6. The end of the strut 2 away from the front cover 1 is hinged to the shaft portion 4211.
[0039] In some embodiments, please refer to Figure 5 The first hinge portion 42 includes a fixed portion 421 and an extension arm 422. The fixed portion 421 is fixed to the fender side sealing plate 3, and the hinge bracket 41 is fixed to the fixed portion 421. The extension arm 422 extends upward from the fixed portion 421 in the negative X direction of the vehicle and forms a cantilever structure. The end of the extension arm 422 away from the fixed portion 421 is hinged to the second hinge portion 43.
[0040] The fixing part 421, the fender side sealing plate 3, and the hinge bracket 41 form a rigid integral structure, which effectively transmits the force.
[0041] The way the bottom end of the fixing part 421 is fixed to the fender side sealing plate 3 is not limited, as long as there is no relative movement between the two. For example, the fixing part 421 and the fender side sealing plate 3 can be welded, screwed, riveted, etc.
[0042] The inclined extension arm 422 can avoid the front hood hinge collision area E as much as possible, and keep the hinge point of the first hinge part 42 and the second hinge part, which have greater rigidity, as far away from the front hood hinge collision area E as possible, thereby reducing the injury to the pedestrian's head during the collision and improving the safety performance of the vehicle's front hood system.
[0043] In one embodiment, the lower part of the fixing part 421 is abutted against and fixed to the side of the fender side sealing plate 3, and the assembly direction of the two is the Y direction of the vehicle. The upper part of the fixing part 421 extends upward beyond the aforementioned horizontal plate part 31. Therefore, the upper part of the fixing part 421 is suspended, and the hinge bracket 41 is abutted against and fixed to the side of the upper part of the fixing part 421, and the assembly direction of the two is the Y direction of the vehicle.
[0044] In some embodiments, please refer to Figure 4 The vehicle front hood system includes a side panel reinforcement 7, which is connected to the fender side sealing plate 3. A first hinge portion 42 is located in front of the side panel reinforcement 7. The first hinge portion 42 and the side panel reinforcement 7 together enclose a hollow channel C for the passage of wiring harnesses. Alternatively, the extension arm 422 has a hollowed-out area for the passage of wiring harnesses. This arrangement improves the space utilization of the vehicle front hood system.
[0045] The wiring harness can be electrically connected to any electrical device. For example, in some embodiments, the support rod 2 is an electric support rod, and the wiring harness is electrically connected to the drive component of the electric support rod to provide power and / or control signals to the drive component.
[0046] In some embodiments, please refer to Figure 4 The vehicle front hood system includes a side panel reinforcement 7, which is connected to the fender side sealing plate 3. The side panel reinforcement 7 and the extension arm 422 are spaced apart from each other and maintain a preset gap D between them, without direct contact or interference.
[0047] When the vehicle front cover system of this application embodiment collides with a pedestrian, the front cover 1 transmits the collision force to the second hinge part 43. The second hinge part 43 rotates downward to the horizontal plate part 31. The existence of the preset gap D can reduce the possibility of the second hinge part 43 directly contacting and interfering with the side wall reinforcement 7 during the rotation process, reduce the injury to the pedestrian's head during the collision, and improve the safety performance of the vehicle front cover system.
[0048] In some embodiments, please refer to Figure 5 The hinge bracket 41 includes a fixed fitting portion 413 and a bending portion 412. The fixed fitting portion 413 abuts against and is fixed to the outer side of the first hinge portion 42 in the Y direction of the vehicle. The bending portion 412 connects the fixed fitting portion 413 and the bending structure 411. The bending portion 412 extends from the top edge of the fixed fitting portion 413 in a direction away from the fixed fitting portion 413, and the top edge of the bending portion 412 is higher than the top edge of the fixed fitting portion 413. The bending structure 411 extends inward from the top edge of the bending portion 412 in the Y direction of the vehicle and exceeds the first hinge portion 42. The bending portion 412, which extends in a direction away from the fixed fitting portion 413, can increase the area of the bending structure 411 and the volume of the first energy-absorbing cavity without interfering with the movement path of the strut 2, thereby improving the deformation energy-absorbing capacity of the hinge bracket 41 and the buffering capacity of the first energy-absorbing cavity.
[0049] The specific shape of the bend 412 is not limited, as long as it extends from the top edge of the fixed mating part 413 in a direction away from the fixed mating part 413. For example, the bend 412 can be arc-shaped, L-shaped, stepped, etc.
[0050] In some embodiments, please refer to Figure 2 The bend 412 includes a first plate portion 4121 and a second plate portion 4122 connected sequentially along the extension path of the bend 412. The first plate portion 4121 and the bending structure 411 face each other in the height direction, and the second plate portion 4122 connects the first plate portion 4121 and the bending structure 411. The first plate portion 4121, the second plate portion 4122, and the bending structure 411 form a U-shaped groove. The U-shaped groove structure can further improve the deformation energy absorption capacity of the hinge bracket 41 and improve the buffering capacity of the first energy absorption cavity.
[0051] In some embodiments, please refer to Figure 2The bending structure 411 includes a mounting plate 4111, with a portion of the fender 5 overlapping the upper surface of the mounting plate 4111. The vehicle hood system includes a first fastener 4112, which connects the fender 5 and the mounting plate 4111 along the vehicle's height direction. The fender 5 is tightly fitted to the mounting plate 4111 via the first fastener 4112, reducing vibration and abnormal noise of the fender 5.
[0052] As one example, please refer to Figure 2 A portion of the top of the fender 5 bends towards the Y-axis of the vehicle and closer to the center vertical plane to form a folded portion 51. The folded portion 51 overlaps the upper surface of the mounting plate 4111. The first fastener 4112 passes through from top to bottom and connects the folded portion 51 and the mounting body. The upper part of the hinge trim 6 bends along the Y-axis of the vehicle and away from the center vertical plane to form a flange 64. The flange 64 is located above the folded portion 51 and the mounting plate 4111. In this way, the fender 5 and the hinge trim 6 form a mutually cooperating shielding structure, shielding the first hinge portion 42 and the hinge bracket 41, protecting the first hinge portion 42 and the hinge bracket 41, and improving the uniformity of the appearance.
[0053] In some embodiments, please refer to Figure 3 The bent structure 411 includes a mounting sidewall 4113 connected to the mounting plate 4111. The mounting sidewall 4113 extends upward at an angle from the mounting body in the negative X-direction of the vehicle. The vehicle front hood system includes a second fastener 4114. A portion of the rear end of the hinge trim 6 overlaps the front surface of the mounting sidewall 4113. The second fastener 4114 connects the hinge trim 6 and the mounting sidewall 4113 along the X-direction of the vehicle. The hinge trim 6 is tightly fitted to the mounting sidewall 4113 via the second fastener 4114, reducing vibration and noise of the hinge trim 6.
[0054] In some embodiments, the hinge trim 6 is a one-piece injection molded part. The one-piece injection molded part is lightweight, which helps to reduce the pressure of the hinge trim 6 on the bend 412; the one-piece injection molded part has good elastic deformation capability, which can play a buffering role during collision.
[0055] This application provides a vehicle, including a vehicle front hood system according to any embodiment of this application. The vehicle front hood system, through the rational arrangement of internal components, forms one or more deformable energy-absorbing structures, which can reduce pedestrian injuries during a collision, improve vehicle safety performance, and thus enable the vehicle to meet collision protection regulations.
[0056] The above embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
