DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The embodiments of the present application provide a front protection device for an automobile, a front cover of an automobile and a vehicle, which can solve the problem that the structure of the calf protection device in the prior art is complex, a large installation space is required in the front end, and a large space is occupied, which affects the available space at the front end of the vehicle.

[0032] like Figure 1 and Figure 2 As shown, on the one hand, the present application provides a front protection device for a vehicle, which includes:

[0033] The front bumper lower lip 1 has a front end for connecting with the front bumper lower skin 6 and a rear end for connecting with the mounting crossbeam 9;

[0034] The support frame 3 is arranged on the inner side of the lower lip 1 of the front bumper. One end of the support frame 3 is connected to the inner side of the front end of the lower lip 1 of the front bumper, and the other end is used to connect to the mounting crossbeam 9. A crushing part is provided inside the support frame 3 for crushing and absorbing energy when impacted.

[0035] When installing the front bumper device, the front end of the front bumper lower lip 1 is connected to the front bumper lower skin 6, and the rear end is connected to the mounting cross beam 9. The support frame 3 is arranged on the inner side of the front bumper lower lip 1, one end of the support frame 3 is connected to the inner side of the front end of the front bumper lower lip 1, and the other end is connected to the mounting cross beam 9. A collapse portion is arranged inside the support frame 3 for collapsing and absorbing energy when impacted. Since the front bumper lower lip 1 is installed on the vehicle frame by the support frame 3 with the collapse portion, the protection effect on pedestrians can be improved by the collapse portion. Compared with the calf protection structure with a driving device, the structure is simpler and the space occupied by the installation is smaller, which solves the problem that the structure of the calf protection device in the prior art is complex, a large installation space needs to be reserved in the front end, and a large space is occupied, which affects the available space at the front end of the vehicle.

[0036] In this example, the front end of the front bumper lower lip 1 protrudes beyond the front end of the front bumper lower skin 6 .

[0037] like Figure 2 As shown, in some optional embodiments, the support frame 3 includes:

[0038] A support plate 32, the front end of which is provided with a front connecting plate 31 connected to the lower lip 1 of the front bumper, and the rear end is used to be connected to the mounting crossbeam 9, a collapse portion is provided in the support plate 32, and the support plate 32 and the front connecting plate 31 are arranged at a set angle;

[0039] The length of the crush support plate 33 is less than that of the support plate 32 , and the rear end of the crush support plate 33 is used to connect with the mounting beam 9 . When the crush portion crushes and absorbs energy, the front connecting plate 31 moves toward the mounting beam 9 until it abuts against the front end of the crush support plate 33 .

[0040] In this embodiment, the structure of the support frame 3 is specifically described. The support frame 3 includes a support plate 32 and a crush support plate 33, wherein the front end of the support plate 32 is provided with a front connecting plate 31 connected to the lower lip 1 of the front bumper, and the rear end is used to connect with the mounting cross beam 9. A crush portion is provided in the support plate 32, and the support plate 32 and the front connecting plate 31 are arranged at a set angle. The length of the crush support plate 33 is less than that of the support plate 32, and the rear end of the crush support plate 33 is used to connect with the mounting cross beam 9. When the crush portion crushes to absorb energy, the front connecting plate 31 moves toward the mounting cross beam 9 until it abuts against the front end of the crush support plate 33, absorbs the kinetic energy generated during the collision through the crush portion, and abuts against the front end of the crush support plate 33 after the crush deformation reaches a certain degree, so as to prevent the pedestrian's calf from being rolled under the vehicle due to excessive deformation, causing secondary injury.

[0041] In this example, the main function of the front connecting plate 31 is to connect the lower lip 1 of the front bumper and support the lower structure of the front bumper. In addition, it also serves as a bearing surface for bearing impact.

[0042] like Figure 1 and Figure 2 As shown, in some optional embodiments, the front end of the front bumper lower lip 1 is higher than the rear end, and the support plate 32 is substantially parallel to the front bumper lower lip 1 .

[0043] In this embodiment, the front end of the front bumper lower lip 1 is higher than the rear end, and the support plate 32 is roughly parallel to the front bumper lower lip 1. When the vehicle goes uphill or passes through some complex terrain, the front bumper lower lip 1 is prevented from contacting the ground, thereby improving the vehicle's passability.

[0044] like Figure 2 As shown, in some optional embodiments, the support plate 32 includes a collapse segment 321 and a rigid support segment 322, the front end of the rigid support segment 322 is connected to the front connecting plate 31, and the rear end is connected to the front end of the collapse segment 321, the rigid support segment 322 abuts against the front end of the collapse support plate 33, and the rear end of the collapse segment 321 is used to connect to the mounting beam 9.

[0045] In this embodiment, the structure of the support plate 32 is specifically described. The support plate 32 includes a collapse section 321 and a rigid support section 322, wherein the front end of the rigid support section 322 is connected to the front connecting plate 31, and the rear end is connected to the front end of the collapse section 321, the rigid support section 322 abuts against the front end of the collapse support plate 33, and the rear end of the collapse section 321 is used to connect to the mounting beam 9, and the front end of the collapse support plate 33 abuts against the rigid support section 322, so that the structural stability is higher. When the collapse portion collapses to absorb energy, the front connecting plate 31 moves toward the mounting beam 9, and the front end of the collapse support plate 33 slides along the rigid support section 322 until it abuts against the front connecting plate 31.

[0046] In this example, since the front bumper of the car is a plastic part, it is easy to deform and sink when heated. Currently, all car companies use bumper brackets to increase the upper fixation, but the lower fixation is not characterized. Therefore, the lower part of the front bumper has no rigid connection and still sinks. In addition, the lower part of the front bumper of the vehicle is a serious collision-prone area. Collisions always cause the replacement and repair of many parts. The cross beam 9 and the front bumper lower lip 1 are connected and installed through the collapse section 321 and the rigid support section 322 to ensure the size of the lower part of the front bumper, reduce the risk of sinking, and reduce the replacement of vehicle parts through secondary collapse energy absorption.

[0047] like Figure 2 As shown, in some optional embodiments, a guide pulley 331 is provided at the front end of the collapse support plate 33 , and the collapse support plate 33 is slidably connected to the rigid support segment 322 via the guide pulley 331 .

[0048] In this embodiment, a guide pulley 331 is provided at the front end of the collapse support plate 33, and the collapse support plate 33 is slidably connected to the rigid support section 322 via the guide pulley 331, thereby ensuring that the front end of the collapse support plate 33 slides more smoothly along the rigid support section 322, thereby preventing stagnation of the sliding process caused by friction.

[0049] like Figure 2 As shown, in some optional embodiments, the collapse section 321 is used to be set on the mounting beam 9 through the rear connecting plate 34, the rear connecting plate 34 is spaced apart from the front connecting plate 31, and the rear connecting plate 34 is connected to the rear end of the collapse support plate 33.

[0050] In this embodiment, the collapse section 321 is used to be set on the mounting beam 9 through the rear connecting plate 34. The rear connecting plate 34 is spaced apart from the front connecting plate 31. The rear connecting plate 34 is connected to the rear end of the collapse support plate 33, which facilitates the collapse section 321 and the collapse support plate 33 to be set on the mounting beam 9, and the connection effect is better.

[0051] In this example, the rear connecting plate 34 is set on the mounting crossbeam 9 by bolts. The bolt connection has reliability, convenience, economy, applicability and diversity. The reliability of the bolt connection is reflected in reliable force transmission, good toughness and plasticity, easy quality inspection, and good dynamic load resistance. The convenience of the bolt connection is reflected in the convenience of loading and unloading. The economy of the bolt connection is reflected in the relatively low price. The applicability of the bolt connection is reflected in the ease of disassembly, and it is suitable for connections and temporary connections that require assembly and disassembly of structures. The diversity of the bolt connection is reflected in the gap between the rod and the hole of the ordinary bolt, the low processing requirements of the through hole, and the simple structure.

[0052] In some optional embodiments, the crush support plate 33 is a bendable member, and when the crush portion is insufficient to absorb impact energy, the crush support plate 33 bends to assist in energy absorption.

[0053] In this embodiment, the crush support plate 33 is configured as a bendable part. When the crush part is not sufficient to absorb the impact energy, the crush support plate 33 bends to assist in energy absorption, thereby further improving the use effect of the front protection device of the automobile and preventing serious damage to the structure when the impact kinetic energy is too large, causing excessive deformation and causing the pedestrian's calf to be rolled under the vehicle, causing secondary injury.

[0054] like Figure 1 and Figure 2 As shown, on the one hand, the present application also provides a front cover of an automobile, which includes:

[0055] The front bumper lower lip 1 has a front end connected to the front bumper lower skin 6 and a rear end connected to the mounting crossbeam 9;

[0056] A support frame 3 is arranged on the inner side of the lower lip 1 of the front bumper, one end of the support frame 3 is connected to the inner side of the front end of the lower lip 1 of the front bumper, and the other end is connected to the mounting crossbeam 9. A collapsing portion is arranged inside the support frame 3 for collapsing and absorbing energy when impacted;

[0057] A front license plate 4, which is located above the front bumper lower lip 1 and connected to the upper side of the front bumper lower skin 6;

[0058] The front marker light 5 is located above the front license plate 4 and is connected to the front license plate 4 through the front bumper upper skin 7.

[0059] When installing the front bumper device, the front end of the front bumper lower lip 1 is connected to the front bumper lower skin 6, and the rear end is connected to the mounting cross beam 9. The support frame 3 is arranged on the inner side of the front bumper lower lip 1, one end of the support frame 3 is connected to the inner side of the front end of the front bumper lower lip 1, and the other end is connected to the mounting cross beam 9. A collapse portion is arranged inside the support frame 3 for collapsing and absorbing energy when impacted. The front license plate 4 is located above the front bumper lower lip 1 and connected to the upper side of the front bumper lower skin 6. The front marker light 5 is located above the front license plate 4 and connected to the front license plate 4 through the front bumper upper skin 7. Since the front bumper lower lip 1 is installed on the vehicle frame through the support frame 3 with the collapse portion, the protection effect on pedestrians can be improved through the collapse portion. Compared with the calf protection structure with a driving device, the structure is simpler and the space occupied by the installation is smaller, which solves the problem that the structure of the calf protection device in the prior art is complex, a large installation space needs to be reserved in the front end, and the space occupied is large, which affects the available space of the front end of the vehicle.

[0060] In this example, an engine hood 8 is also provided on the front cover of the automobile.

[0061] In this embodiment, the structure of the support frame 3 is specifically described. The support frame 3 includes a support plate 32 and a crush support plate 33, wherein the front end of the support plate 32 is provided with a front connecting plate 31 connected to the lower lip 1 of the front bumper, and the rear end is used to connect with the mounting cross beam 9. A crush portion is provided in the support plate 32, and the support plate 32 and the front connecting plate 31 are arranged at a set angle. The length of the crush support plate 33 is less than that of the support plate 32, and the rear end of the crush support plate 33 is used to connect with the mounting cross beam 9. When the crush portion crushes to absorb energy, the front connecting plate 31 moves toward the mounting cross beam 9 until it abuts against the front end of the crush support plate 33, absorbs the kinetic energy generated during the collision through the crush portion, and abuts against the front end of the crush support plate 33 after the crush deformation reaches a certain degree, so as to prevent the pedestrian's calf from being rolled under the vehicle due to excessive deformation, causing secondary injury.

[0062] In this embodiment, the front end of the front bumper lower lip 1 is higher than the rear end, and the support plate 32 is roughly parallel to the front bumper lower lip 1. When the vehicle goes uphill or passes through some complex terrain, the front bumper lower lip 1 is prevented from contacting the ground, thereby improving the vehicle's passability.

[0063] In this embodiment, the structure of the support plate 32 is specifically described. The support plate 32 includes a collapse section 321 and a rigid support section 322, wherein the front end of the rigid support section 322 is connected to the front connecting plate 31, and the rear end is connected to the front end of the collapse section 321, the rigid support section 322 abuts against the front end of the collapse support plate 33, and the rear end of the collapse section 321 is used to connect to the mounting beam 9, and the front end of the collapse support plate 33 abuts against the rigid support section 322, so that the structural stability is higher. When the collapse portion collapses to absorb energy, the front connecting plate 31 moves toward the mounting beam 9, and the front end of the collapse support plate 33 slides along the rigid support section 322 until it abuts against the front connecting plate 31.

[0064] In this example, since the front bumper of the car is a plastic part, it is easy to deform and sink when heated. Currently, all car companies use bumper brackets to increase the upper fixation, but the lower fixation is not characterized. Therefore, the lower part of the front bumper has no rigid connection and still sinks. In addition, the lower part of the front bumper of the vehicle is a serious collision-prone area. Collisions always cause the replacement and repair of many parts. The cross beam 9 and the front bumper lower lip 1 are connected and installed through the collapse section 321 and the rigid support section 322 to ensure the size of the lower part of the front bumper, reduce the risk of sinking, and reduce the replacement of vehicle parts through secondary collapse energy absorption.

[0065] In this embodiment, a guide pulley 331 is provided at the front end of the collapse support plate 33, and the collapse support plate 33 is slidably connected to the rigid support section 322 via the guide pulley 331, thereby ensuring that the front end of the collapse support plate 33 slides more smoothly along the rigid support section 322, thereby preventing stagnation of the sliding process caused by friction.

[0066] In this embodiment, the collapse section 321 is used to be set on the mounting beam 9 through the rear connecting plate 34. The rear connecting plate 34 is spaced apart from the front connecting plate 31. The rear connecting plate 34 is connected to the rear end of the collapse support plate 33, which facilitates the collapse section 321 and the collapse support plate 33 to be set on the mounting beam 9, and the connection effect is better.

[0067] In this embodiment, the crush support plate 33 is configured as a bendable part. When the crush part is not sufficient to absorb the impact energy, the crush support plate 33 bends to assist in energy absorption, thereby further improving the use effect of the front protection device of the automobile and preventing serious damage to the structure when the impact kinetic energy is too large, causing excessive deformation and causing the pedestrian's calf to be rolled under the vehicle, causing secondary injury.

[0068] like Figure 1 As shown, in some optional embodiments, the front end of the front bumper lower lip 1 protrudes beyond the front end of the front bumper lower skin 6 .

[0069] In this embodiment, the front end of the lower lip 1 of the front bumper protrudes out of the front end of the front bumper lower skin 6, providing sufficient support for the calf part to prevent the calf from bending in the opposite direction, thereby improving safety.

[0070] In this example, the lower lip 1 of the front bumper corresponds to the calf of the dummy 2; the front license plate 4 corresponds to the knee of the dummy 2, supporting the knee position to ensure the support force in the middle of the leg, with a height of about 450 mm; the front marker light 5 corresponds to the thigh of the dummy 2, and the front end of the front marker light 5 protrudes from the front bumper upper skin 7 to support the upper part of the thigh, and the front marker light 5 and the front bumper upper skin 7 maintain a small angle offset toward the rear end, trying to keep the front end flush to reduce the immediate damage during the collision.

[0071] like Figure 1 and Figure 2 As shown, on the other hand, the present application also provides a vehicle, which includes the above-mentioned automobile front protection device.

[0072] When installing the front bumper device, the front end of the front bumper lower lip 1 is connected to the front bumper lower skin 6, and the rear end is connected to the mounting cross beam 9. The support frame 3 is arranged on the inner side of the front bumper lower lip 1, one end of the support frame 3 is connected to the inner side of the front end of the front bumper lower lip 1, and the other end is connected to the mounting cross beam 9. A collapse portion is arranged inside the support frame 3 for collapsing and absorbing energy when impacted. Since the front bumper lower lip 1 is installed on the vehicle frame by the support frame 3 with the collapse portion, the protection effect on pedestrians can be improved by the collapse portion. Compared with the calf protection structure with a driving device, the structure is simpler and the space occupied by the installation is smaller, which solves the problem that the structure of the calf protection device in the prior art is complex, a large installation space needs to be reserved in the front end, and a large space is occupied, which affects the available space at the front end of the vehicle.

[0073] In this embodiment, the structure of the support frame 3 is specifically described. The support frame 3 includes a support plate 32 and a crush support plate 33, wherein the front end of the support plate 32 is provided with a front connecting plate 31 connected to the lower lip 1 of the front bumper, and the rear end is used to connect with the mounting cross beam 9. A crush portion is provided in the support plate 32, and the support plate 32 and the front connecting plate 31 are arranged at a set angle. The length of the crush support plate 33 is less than that of the support plate 32, and the rear end of the crush support plate 33 is used to connect with the mounting cross beam 9. When the crush portion crushes to absorb energy, the front connecting plate 31 moves toward the mounting cross beam 9 until it abuts against the front end of the crush support plate 33, absorbs the kinetic energy generated during the collision through the crush portion, and abuts against the front end of the crush support plate 33 after the crush deformation reaches a certain degree, so as to prevent the pedestrian's calf from being rolled under the vehicle due to excessive deformation, causing secondary injury.

[0074] In this embodiment, the front end of the front bumper lower lip 1 is higher than the rear end, and the support plate 32 is roughly parallel to the front bumper lower lip 1. When the vehicle goes uphill or passes through some complex terrain, the front bumper lower lip 1 is prevented from contacting the ground, thereby improving the vehicle's passability.

[0075] In this embodiment, the structure of the support plate 32 is specifically described. The support plate 32 includes a collapse section 321 and a rigid support section 322, wherein the front end of the rigid support section 322 is connected to the front connecting plate 31, and the rear end is connected to the front end of the collapse section 321, the rigid support section 322 abuts against the front end of the collapse support plate 33, and the rear end of the collapse section 321 is used to connect to the mounting beam 9, and the front end of the collapse support plate 33 abuts against the rigid support section 322, so that the structural stability is higher. When the collapse portion collapses to absorb energy, the front connecting plate 31 moves toward the mounting beam 9, and the front end of the collapse support plate 33 slides along the rigid support section 322 until it abuts against the front connecting plate 31.

[0076] In this example, since the front bumper of the car is a plastic part, it is easy to deform and sink when heated. Currently, all car companies use bumper brackets to increase the upper fixation, but the lower fixation is not characterized. Therefore, the lower part of the front bumper has no rigid connection and still sinks. In addition, the lower part of the front bumper of the vehicle is a serious collision-prone area. Collisions always cause the replacement and repair of many parts. The cross beam 9 and the front bumper lower lip 1 are connected and installed through the collapse section 321 and the rigid support section 322 to ensure the size of the lower part of the front bumper, reduce the risk of sinking, and reduce the replacement of vehicle parts through secondary collapse energy absorption.

[0077] In this embodiment, a guide pulley 331 is provided at the front end of the collapse support plate 33, and the collapse support plate 33 is slidably connected to the rigid support section 322 via the guide pulley 331, thereby ensuring that the front end of the collapse support plate 33 slides more smoothly along the rigid support section 322, thereby preventing stagnation of the sliding process caused by friction.

[0078] In this embodiment, the collapse section 321 is used to be set on the mounting beam 9 through the rear connecting plate 34. The rear connecting plate 34 is spaced apart from the front connecting plate 31. The rear connecting plate 34 is connected to the rear end of the collapse support plate 33, which facilitates the collapse section 321 and the collapse support plate 33 to be set on the mounting beam 9, and the connection effect is better.

[0079] In this embodiment, the crush support plate 33 is configured as a bendable part. When the crush part is not sufficient to absorb the impact energy, the crush support plate 33 bends to assist in energy absorption, thereby further improving the use effect of the front protection device of the automobile and preventing serious damage to the structure when the impact kinetic energy is too large, causing excessive deformation and causing the pedestrian's calf to be rolled under the vehicle, causing secondary injury.

[0080] In summary, when installing the front bumper device, the front end of the front bumper lower lip 1 is connected to the front bumper lower skin 6, and the rear end is connected to the mounting crossbeam 9. The support frame 3 is arranged on the inner side of the front bumper lower lip 1, one end of the support frame 3 is connected to the inner side of the front end of the front bumper lower lip 1, and the other end is connected to the mounting crossbeam 9. A collapse portion is arranged inside the support frame 3 for collapsing and absorbing energy when impacted. Since the front bumper lower lip 1 is installed on the vehicle frame by the support frame 3 with the collapse portion, the protection effect on pedestrians can be improved by the collapse portion. Compared with the calf protection structure with a driving device, the structure is simpler and the space occupied by the installation is smaller, which solves the problem that the structure of the calf protection device in the prior art is complex, a large installation space needs to be reserved in the front end, and a large space is occupied, which affects the available space at the front end of the vehicle.
