A front penetration light assembly

technical field

The present application relates to the technical field of automobile bodies, and in particular, to a front penetration lamp assembly.

Background technique

With the popularization of automobiles and the increase of the total number of automobiles, the automobile traffic safety is also being upgraded simultaneously. The expansion of urban roads and even the optimization of automobile parts are undoubtedly to ensure the high-efficiency traffic brought by automobiles, and at the same time protect personal safety; Among them, from the perspective of the development trend of automobiles of various brands, the front penetrating lights in automobile design are more and more common, and it has become an aesthetic trend and is increasingly popular. The front penetrating lights greatly improve the recognition of the front face of the car, and at the same time Make the car more technological and futuristic.

In the related art, the front penetration lamp has the following two installation methods:

First, the front penetrating light 4 is directly installed on the front frame 3. Referring to FIG. 1, the front penetrating light 4 is directly installed on the front frame 3 through the installation point. In this installation method, the front penetrating light 4 and the front frame 3 The distance between them is relatively short, which can prevent the overhang from being too large, causing the problem of increasing the gap between the front bumper 2 and the front cover. However, because there is not enough space between the front penetration light 4 and the front frame 3, when a pedestrian collides with a vehicle, The front penetrating light 4 cannot be moved backward, which causes great damage to the pedestrian's thigh and cannot effectively protect the pedestrian.

Second, the front penetration light 4 is installed on the front frame 3 through the support frame 1. Referring to FIG. 2, the front penetration light 4 is first installed on a support frame 1 through the installation point, and the support frame 1 is then installed on the support frame 1 through the installation point. However, since the space between the front through lamp 4 and the front frame 3 is occupied by the support frame 1, the support frame 1 mainly plays the role of supporting the front through lamp 4 and the front bumper 2, and in order to support the front through lamp 1 And the weight of the front bumper 2, the rigidity of the support frame 1 needs to be larger, generally using PP-GF30 (glass fiber reinforced polypropylene, glass fiber content 30%) material, resulting in the collision between pedestrians and vehicles, the support frame 1 It is not easy to be deformed, and the damage to pedestrians' thighs is very large, and it cannot effectively protect pedestrians.

SUMMARY OF THE INVENTION

The embodiment of the present application provides a front penetration light assembly to solve the problem in the related art that when a pedestrian collides with a vehicle, the front penetration light cannot be moved backward or the support is rigid and not easily deformed, causing great damage to the pedestrian's thigh. .

In a first aspect, a front penetration light assembly is provided, which includes:

a front-end frame, on which a resisting piece is arranged;

a front bumper, with a crumpling space formed between it and the front-end frame;

A brittle support frame, which is accommodated in the crumpling space, and two sides of the support frame are respectively connected with the front end frame and the front bumper; socket;

a front penetration light connected to the support bracket through the front bumper; and,

When a pedestrian collides with a vehicle, the abutting member is used for passing through the socket and abutting on the front bumper to support the front bumper.

In the related art, the support frame mainly plays the role of supporting the front penetrating lamp and the front bumper, and in order to support the weight of the front penetrating lamp and the front bumper, the rigidity of the supporting frame needs to be relatively large, and PP-GF30 (glass fiber) is generally used. Reinforced polypropylene, glass fiber content 30%) material, so that when pedestrians collide with vehicles, the support frame is not easy to deform, the damage to pedestrians' thighs is very large, and it cannot effectively protect pedestrians.

However, the support frame of the embodiment of the present application mainly plays the role of supporting the front through light, and uses the front-end frame to support the front bumper through the cooperation between the abutting member and the socket. Therefore, the support frame of the embodiment of the present application faces the front bumper. The support force of the bumper is shared by the front-end frame; then the support frame does not need to select materials with higher rigidity, for example, PP-TD10 (talcum powder modified polypropylene, talcum powder content is 10%) can be used. The brittleness of the material is good. When a pedestrian collides with a vehicle, the support frame can collapse and deform in the collapse space, and drive the front penetration light to move backward (to move toward the front-end frame). The front penetration light assembly will not cause hard damage to the pedestrian's thigh, and can effectively protect the pedestrian.

Moreover, when a pedestrian collides with a vehicle, the front bumper will be loose and fall down, and in the embodiment of the present application, through the cooperation between the abutting member and the socket, the abutting member is used to support the front bumper, Not only supports the front bumper, but also prevents the front bumper from falling down.

In some embodiments, the front bumper has an impact area and a non-impact area, and the socket is mounted in the non-impact area.

According to the collision simulation experiment, the collision area where the front bumper collides with the pedestrian's thigh, and the non-collision area where the front bumper does not collide with the pedestrian's thigh can be obtained. The front penetrating light of the present application also collides with the pedestrian's thigh, but the contact area between the front penetrating light and the pedestrian's thigh is small, and is not subject to the main impact of the pedestrian's thigh, and the contact area between the pedestrian's thigh and the collision area of the front bumper is large, The impact occurs mainly in the collision zone. Furthermore, if the socket is installed in the non-collision area, when a pedestrian collides in the collision area, the abutting member passes through the socket and abuts in the non-collision area of the front bumper, which not only will not hinder the collapse and deformation of the support frame, but also It will not directly give the support force to the front bumper in the collision area, which can support the front bumper without increasing the damage to the pedestrian's thigh.

In some embodiments:

forming the crumple space between the collision area and the front end frame;

The support frame includes:

a first frame housed in the crumpling space;

One end of the second frame body is connected with the bottom end of the first frame body, and the other end extends into the non-collision area, and the socket is arranged on the second frame body.

The first frame body accommodated in the crumpling space is adapted to the shape of the collision area of the front bumper, and when a pedestrian collides with the collision area, the first frame body collapses and deforms in the crumpling space, and drives the first frame body. The two frame bodies collapse and deform, thereby driving the front penetrating lights connected with the second frame body to move backward together, weakening the collision force of pedestrians, and greatly reducing the damage to pedestrians' thighs.

Furthermore, the socket is set on the second frame body, away from the collision area, so when a pedestrian collides in the collision area, the abutting member passes through the socket and abuts in the non-collision area of the front bumper, not only will it not hinder the first frame. The collapse and deformation of the body will not directly give the support force to the front bumper in the collision area, which can support the front bumper without increasing the damage to the pedestrian's thigh.

In some embodiments, the first frame is U-shaped and includes:

a horizontally arranged first section, the first section is connected with the top end of the front-end frame;

an arc-shaped second segment, one end of the second segment is connected with the first segment, and the other end extends obliquely along the inner surface of the collision area;

One end of the third segment is connected to the other end of the second segment, and the other end is connected to the second frame body.

The collision area of the front bumper is arc-shaped, protruding in the direction away from the front-end frame, and forming a large crumpling space with the front-end frame, the first frame body is accommodated in the crumpling space in a U-shape, The second segment is adapted to the inner surface of the collision area to increase the contact area with the collision area, which can basically transmit and dissipate the collision force applied to the collision area; and the U formed by the first, second and third segments There is also a large space between the first frame body and the crumpling space, which is enough for the second segment to perform crumpling deformation. The collapse energy dissipation principle of the first frame of the embodiment of the present application is as follows:

When the pedestrian collides with the collision area, since the second segment is adapted to the inner surface of the collision area, and the second segment is all in contact with the collision area, the collision force applied in the collision area is all transferred to the second segment, and the second segment is completely in contact with the collision area. The segment collapses to dissipate most of the collision force, the remaining collision force is transmitted to the front frame through the first segment, and a small amount of collision force is transmitted to the second frame through the third segment. So as to achieve the dissipation of the collision force. Moreover, the horizontal arrangement of the first section can directly dissipate the collision force in the vertical direction, and since there is a bending angle between the first section and the second section, the energy of the collision force passing through the bending angle will also be greatly weakened.

In some embodiments, the third segment is arranged in parallel with the first segment.

First, the third section is arranged in parallel with the first section, which makes the forming structure of the first frame simpler and symmetrical, which greatly reduces the forming process of the support frame and is suitable for mass production; The collision force in the vertical direction is dissipated, and since there is a bending angle between the first segment and the second segment, the energy of the collision force passing through the bending angle is also greatly weakened.

In some embodiments, the second frame includes:

a support plate, which is connected to the third section, and the front through-light is connected to the support plate;

Two supporting feet, the two supporting feet are respectively arranged at two ends of the support plate; and the sockets are opened on the supporting feet.

The outer contour shape of the support plate is adapted to the front penetrating lamp, and has a good supporting effect on the front penetrating lamp. Since the front-end frame is square, the two legs are designed to be connected to the two frames of the front-end frame respectively, which saves materials, reduces the weight of the support frame, and realizes a lightweight design.

In some embodiments:

The support plate is connected with the end of the third section away from the second section, and a step is formed between the two; the support plate is provided with a first installation slot; the front bumper is provided with a a second installation groove adapted to the first installation groove;

The front penetrating lamp includes a front penetrating lamp body, and a plug connector disposed on the front penetrating lamp body, the front penetrating lamp body is located in the step, and the plug connector penetrates through the second installation slot and the first installation slot.

The crushing energy dissipation principle of the support frame of the embodiment of the present application is as follows:

When the pedestrian collides with the collision area, since the second segment is adapted to the inner surface of the collision area, and the second segment is all in contact with the collision area, the collision force applied in the collision area is all transferred to the second segment, and the second segment is completely in contact with the collision area. The segment collapses to dissipate most of the collision force, the remaining collision force is transmitted to the front frame through the first segment, and a small amount of collision force is transmitted to the support plate through the third segment to achieve the dissipation of the collision force. Since a step is formed between the support plate and the third section, when the collision force passes through the step, its ability will be greatly weakened, and the support plate will also move backwards with the third section, thereby driving the front penetrating lamp body backwards together move; then the part of the pedestrian's thigh in contact with the front penetrating lamp body will also retract later. When the front penetrating lamp body is completely accommodated in the steps, the pedestrian's thigh will be separated from the front penetrating lamp body, thus protecting the front penetrating lamp body and pedestrians. The role of the thigh.

In some embodiments, one end of the socket is connected to the support frame, and the other end is protruded toward the front frame.

When the pedestrian does not collide with the vehicle, the abutting member does not fully protrude from the socket; when the pedestrian collides with the vehicle, the protruding end of the socket will press against the abutting member, and the abutting member protrudes from the socket and It resists against the front bumper to offset the collision force of pedestrians, which can weaken the collision force and minimize the damage to pedestrians' thighs.

In some embodiments, the socket is located below the front penetrating light.

The socket is located below the front penetrating light, which means that the socket is not located in the area where pedestrians collide with the front bumper, and it will not occupy the crumpling space, so as not to affect the collapse of the support frame and the front penetrating light.

In some embodiments, the socket is square, the length of the socket along the vehicle body width direction is greater than the diameter of the resisting member, and the length of the socket along the vehicle body height direction is equal to the diameter of the resisting member.

When a collision occurs, the front bumper will move along the length, width and height directions of the vehicle body. In order not to restrict the movement of the front bumper along the width and length directions of the vehicle body, the length of the socket along the width direction of the vehicle body is designed to be greater than The diameter of the holding piece can avoid direct hard collision between the front bumper and pedestrians, so as to weaken the hard injury of the front bumper to pedestrians’ thighs; in order to limit the movement of the front bumper along the vehicle height direction, the length of the socket along the vehicle height direction is designed to be Equal to the diameter of the abutment to prevent the front bumper from falling off.

The beneficial effects brought by the technical solution provided by this application include:

1. The support frame of the embodiment of the present application mainly plays the role of supporting the front through light, and uses the front-end frame to support the front bumper through the cooperation between the resisting member and the socket. Therefore, the support frame of the embodiment of the present application is suitable for The support force of the front bumper is shared by the front frame; then the support frame does not need to select materials with higher rigidity, for example, PP-TD10 (talcum powder modified polypropylene, talcum powder content is 10%) can be used. The brittleness of this material is good. When a pedestrian collides with a vehicle, the support frame can collapse and deform in the collapse space, and drive the front penetration lamp to move backward (to move toward the front frame), so the embodiment of the present application The front penetration light assembly will not cause hard damage to pedestrians' thighs and can effectively protect pedestrians.

2. When a pedestrian collides with a vehicle, the front bumper will loosen and fall down.

Obviously, the described embodiments It is a part of the embodiments of this application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present application.

Referring to FIGS. 3-6 , FIG. 3 is a schematic structural diagram of a front end frame; FIG. 4 is a structural schematic diagram of a front penetration lamp assembly (excluding the front bumper) provided by an embodiment of the application; A cross-sectional view in the direction B-B; FIG. 6 is a schematic structural diagram of a front through-lamp assembly (including a front bumper) provided by an embodiment of the application. The invention can solve the problem in the related art that when a pedestrian collides with a vehicle, the front penetrating light cannot be moved backwards or the supporting member has high rigidity and is not easily deformed, thereby causing great damage to the pedestrian's thigh.

The embodiment of the present application provides a front penetration light assembly, which includes a front end frame 3, a front bumper 2, a brittle support frame 1 and a front penetration light 4, and a resisting member 30 is provided on the front end frame 3; the front bumper A crush space 5 is formed between 2 and the front frame 3; the brittle support frame 1 is accommodated in the crush space 5, and the two sides of the support frame 1 are respectively connected with the front frame 3 and the front bumper 2; A socket 10 is opened through the support frame 1; the front through-light 4 is connected to the support frame 1 through the front bumper 2; on the front bumper 2 to support the front bumper 2 .

In the related art, the support frame 1 mainly plays the role of supporting the front penetrating lamp 4 and the front bumper 2, and in order to support the weight of the front penetrating lamp 1 and the front bumper 2, the rigidity of the supporting frame 1 needs to be relatively large, generally using PP-GF30 (glass fiber reinforced polypropylene, glass fiber content 30%) material, the support frame 1 is not easily deformed when a pedestrian collides with a vehicle, which causes great damage to the pedestrian's thigh and cannot effectively protect the pedestrian.

However, the support frame 1 in the embodiment of the present application mainly plays the role of supporting the front through lamp 4, and uses the front frame 3 to support the front bumper 2 through the cooperation between the abutting member 30 and the socket 10. Therefore, the present application implements In the example, the supporting force of the front bumper 2 by the support frame 1 is shared by the front end frame 3; then the support frame 1 does not need to select a material with greater rigidity, for example, PP-TD10 (talcum powder modified polypropylene, The content of talcum powder is 10%), the brittleness of this material is good, when the pedestrian collides with the vehicle, the support frame 1 can collapse and deform in the collapse space 5, and drive the front penetration lamp 4 to move backward (towards the close The direction of the front end frame 3 moves), so the front penetration lamp assembly of the embodiment of the present application will not cause hard damage to the pedestrian's thigh, and can effectively protect the pedestrian.

Moreover, when a pedestrian collides with a vehicle, the front bumper 2 may become loose and fall down. In the embodiment of the present application, through the cooperation between the abutting member 30 and the socket 10, the abutting member 30 is used to support the front bumper 30. The bumper 2 can not only support the front bumper 2, but also prevent the front bumper 2 from falling down.

Optionally, as shown in FIG. 5 , one end of the socket 10 is connected to the support frame 1 , and the other end protrudes toward the front frame 3 .

When the pedestrian does not collide with the vehicle, the resisting member 30 does not completely extend from the socket 10; when the pedestrian collides with the vehicle, the protruding end of the socket 10 is pressed against the resisting member 30, and the resisting member 30 It protrudes from the socket 10 and bears against the front bumper 2, so as to counteract the collision force of pedestrians, which can weaken the collision force and minimize the damage to the thighs of pedestrians.

Preferably, the socket 10 is located below the front penetrating lamp 4 and is 100mm-200mm away from the front penetrating lamp.

The socket 10 is located below the front penetrating light 4, which means that the socket 10 is not located in the area where pedestrians collide with the front bumper 2, so it will not occupy the collapse space 5, so as not to affect the collapse of the support frame 1 and the front penetrating light 4. .

Preferably, the socket 10 is square, the length of the socket 10 in the width direction of the vehicle body is greater than the diameter of the abutting member 30 , and the length of the socket 10 in the height direction of the vehicle body is equal to the diameter of the abutting member 30 .

When a collision occurs, the front bumper 2 will move along the length, width and height directions of the vehicle body. In order not to restrict the movement of the front bumper 2 along the width and length directions of the vehicle body, the length of the socket 10 along the width direction of the vehicle body is designed. The diameter of the front bumper 2 is larger than the diameter of the resisting member 30 to avoid direct hard collision between the front bumper 2 and pedestrians, so as to weaken the hard injury of the front bumper 2 to the pedestrian’s thighs; The length in the vehicle height direction is designed to be equal to the diameter of the abutting member 30 to prevent the front bumper 2 from falling down.

Referring to FIG. 6 , the front bumper 2 has a collision area 20 and a non-collision area 21 , and the socket 10 is installed in the non-collision area 21 .

According to the collision simulation experiment, the collision area 20 where the front bumper 2 collides with the pedestrian's thigh, and the non-collision area 21 where the collision does not collide with the pedestrian's thigh can be obtained. The front penetrating light 4 of the first embodiment of the present application also collides with the pedestrian's thigh, but the contact area between the front penetrating light 4 and the pedestrian's thigh is small, and is not subject to the main impact of the pedestrian's thigh, and the collision between the pedestrian's thigh and the front bumper 2 The contact area of the area 20 is large, and the collision mainly occurs in the collision area 20 . Furthermore, if the socket 10 is installed in the non-collision area 21 , when a pedestrian collides with the collision area 20 , the abutting member 30 passes through the socket 10 and abuts in the non-collision area 21 of the front bumper 2 , not only will not hinder the support The crushing deformation of the frame 1 will not directly give the support force to the front bumper 2 in the collision area 20, which can support the front bumper 2 without increasing the injury to the pedestrian's thigh.

7-9, further, a crush space 5 is formed between the collision area 20 and the front frame 3; the support frame 1 includes a first frame body 11 accommodated in the crush space 5, and a second frame One end of the second frame body 12 is connected to the bottom end of the first frame body 11 , the other end extends into the non-collision area 21 , and the socket 10 is provided on the second frame body 12 .

The first frame body 11 accommodated in the crush space 5 is adapted to the shape of the collision area 20 of the front bumper 2 , and when a pedestrian collides with the collision area 20 , the first frame body 11 occurs in the crush space 5 . Collapse deformation, and drive the second frame body 12 to collapse and deform, thereby driving the front penetrating light 4 connected to the second frame body 12 to move backward together, weakening the collision force of pedestrians, and greatly reducing the damage to pedestrians' thighs .

Furthermore, the socket 10 is provided on the second frame body 12 and is installed in the non-collision area 21 , then when a pedestrian collides with the collision area 20 , the abutting member 30 passes through the socket 10 and abuts against the non-collision area of the front bumper 2 . In the area 21, not only will it not hinder the collapse and deformation of the first frame body 11, but also will not directly give the support force to the front bumper 2 in the collision area 20, which can support the front bumper 2 without increasing the resistance Pedestrian thigh injury.

Referring to FIG. 7 , further, the first frame body 11 is U-shaped, which includes a horizontally arranged first segment 110 , an arc-shaped second segment 111 and a third segment 112 , the first segment 110 and the front-end frame 3 One end of the second segment 111 is connected to the first segment 110, and the other end extends obliquely along the inner surface of the collision area 20; one end of the third segment 112 is connected to the other end of the second segment 111, and the other end is connected to the second frame Body 12 is connected.

The collision area 20 of the front bumper 2 is arc-shaped, protruding in the direction away from the front-end frame 3, and a large crumpling space 5 is formed between the front-end frame 3 and the first frame body 11 in a U-shape. In the shrink space 5, the second section 111 is adapted to the inner surface of the collision area 20, increasing the contact area with the collision area 20, and can basically transmit and dissipate the collision force applied to the collision area 20; and the first section 110 There is also a large space between the U-shaped first frame body 11 formed by the second segment 111 and the third segment 112 and the crushing space 5, which is sufficient for the second segment 111 to undergo crushing deformation. The collapse energy dissipation principle of the first frame body 11 in the embodiment of the present application is as follows:

When a pedestrian collides with the collision area 20, since the second segment 111 is adapted to the inner surface of the collision area 20, and the second segment 111 is all in contact with the collision area 20, the collision force applied in the collision area 20 is all transmitted to the collision area 20. The second section 111 , the second section 111 collapses to dissipate most of the collision force, the remaining collision force is transmitted to the front frame 3 through the first section 110 , and a small amount of collision force is transmitted to the second frame through the third section 112 body 12. So as to achieve the dissipation of the collision force. Moreover, the horizontal arrangement of the first section 110 can directly dissipate the collision force in the vertical direction, and since the first section 110 and the second section 111 have a bending angle, the energy of the collision force passing through the bending angle will also be greatly weakened.

Referring to FIG. 7 , further, the third segment 112 is arranged in parallel with the first segment 110 .

First, the third section 112 is arranged in parallel with the first section 110, which makes the molding structure of the first frame body 11 simpler and more symmetrical, greatly reduces the molding process of the support frame 1, and is suitable for mass production; furthermore, the third section 112 The horizontal arrangement can directly dissipate the collision force in the vertical direction, and since the first section 110 and the second section 111 have a bending angle, the energy of the collision force passing through the bending angle will also be greatly weakened.

Referring to FIG. 9 , the second frame body 12 includes a support plate 121 and two legs 120. The support plate 121 is connected to the third section 112, and the front through light 4 is connected to the support plate 121; the two legs 120 are respectively provided on the support plate 121. The two ends of the board 121;

The outer contour shape of the support plate 121 is adapted to the front penetrating lamp 4 , and has a better supporting effect on the front penetrating lamp 4 . Since the front frame 3 is square, the two legs 120 are designed to be connected to the two frames of the front frame 3 respectively, which saves materials and reduces the weight of the support frame 1, thereby realizing a lightweight design.

Referring to FIG. 7, further, the support plate 121 is connected to the end of the third section 112 away from the second section 111, and a step 6 is formed between the two; the support plate 121 is provided with a first installation slot 13; The bumper 2 is provided with a second installation groove which is adapted to the first installation groove 13; the front penetration lamp 4 includes a front penetration lamp body 41 and a connector 40 arranged on the front penetration lamp body 41. The front penetration lamp The body 41 is located in the step 6 , and the plug 40 penetrates through the second installation groove and the first installation groove 13 .

The crushing energy dissipation principle of the support frame 1 in the embodiment of the present application is as follows:

When a pedestrian collides with the collision area 20, since the second segment 111 is adapted to the inner surface of the collision area 20, and the second segment 111 is all in contact with the collision area 20, the collision force applied in the collision area 20 is all transmitted to the collision area 20. The second section 111 , the second section 111 collapses to dissipate most of the collision force, the remaining collision force is transmitted to the front frame 3 through the first section 110 , and a small amount of collision force is transmitted to the support plate 121 through the third section 112 , to achieve the dissipation of the collision force. Since the step 6 is formed between the support plate 121 and the third section 112, when the collision force passes through the step, its ability will be greatly weakened, and the support plate 121 will move backward together with the third section 112, thereby driving the forward penetration The lamp body 41 moves backward together; then the part of the pedestrian's thigh in contact with the front penetrating lamp body 41 will also shrink back. When the front penetrating lamp body 41 is completely accommodated in the step 6, the pedestrian's thigh will be separated from the front penetrating lamp body 41. Thereby, it plays the role of protecting the front penetrating lamp body 41 and the pedestrian's thigh.

Referring to FIG. 9 , the first frame body 11 is provided with a plurality of crush holes 14 .

By opening a plurality of crush holes 14 on the first frame body 11, after the first frame body 11 is subjected to a collision force, the stress is concentrated at the crush holes 14, thereby realizing the crushing deformation of the first frame body 11, so as to achieve energy dissipation effect.
