Abstract
Description
Technical Field

[0002] In the development process of vehicles, electrification and intelligence are increasingly valued by consumers. The design concept of through lights with rich and dazzling lighting effects is used in more and more vehicle models. A vehicle lamp component, such as a through light, is usually located at the front end of the vehicle, at the position where a pedestrian's leg hits. Under the requirements of non-offset of the light, weight mode, protection of internal electronic devices, and the hardness of the housing itself, the stiffness and strength of the through light itself are relatively large, and the traditional installation method of the through light is mainly to directly install it on the front frame crossbeam, and the whole has high strength. When a pedestrian hits the front end of the vehicle, the impact energy of the leg needs to simultaneously cause the installation bracket of the through light and the front bumper bracket to fail in order to cause the leg to collapse and deform, which will cause serious harm to the pedestrian's leg and the like.

[0025] The present application provides a connection component, such asFigures 1 to 4 As shown Figure 1 is a schematic structural diagram of an embodiment of the assembly structure of the connection component and the headlight component of the present application; Figure 2 is Figure 1 a side view schematic diagram of the embodiment; Figure 3 is a schematic structural diagram of an embodiment of the connection component of the present application; Figure 4 is Figure 3 Another side view schematic diagram of the connection component of the embodiment. In this embodiment, the connection component 2 is used to connect the front bumper (not shown in the figure) of the vehicle and the headlight component 1. The connection component 2 includes a front bumper bracket 21 and a connection bracket 22. Among them, the front end face (not marked in the figure) of the front bumper bracket 21 is configured to install the front bumper; the connection bracket 22 is connected to the upper end face (not marked in the figure) of the front bumper bracket 21. The front end face (not marked in the figure) of the connection bracket 22 is configured to install the headlight component 1, and a collapse space is formed at the rear end face (not marked in the figure) of the connection bracket 22; a collapse portion 211 is provided on the upper end face of the front bumper bracket 21, and the connection bracket 22 is arranged closer to the front end face of the front bumper bracket 21 relative to the collapse portion 211.
[0026] Among them, the front end face of the front bumper bracket 21 refers to the side of the front bumper bracket 21 facing the front of the vehicle when the vehicle is in use, and the front end face of the front bumper bracket 21 can be used to install the front bumper; the upper end face of the front bumper bracket 21 refers to the side of the front bumper bracket 21 facing the upper part of the vehicle when the vehicle is in use, and can be used to install the headlight component 1; the front end face of the connection bracket 22 refers to the side of the connection bracket 22 facing the front of the vehicle when the vehicle is in use, and the front end face of the connection bracket 22 can be used to install the headlight component 1, so that the headlight component is located above the front bumper and the front bumper bracket 21; the rear end face of the connection bracket 22 refers to the side of the connection bracket 22 facing the rear of the vehicle when the vehicle is in use; the connection bracket 22 is arranged closer to the front end face of the front bumper bracket 21 relative to the collapse portion 211 means that, along the front-rear direction of the vehicle, the collapse portion 211 is located behind the connection bracket 22. The headlight component 1 can be a front through headlight component of the vehicle, etc.
[0027] In the above manner, on the one hand, a crush space 221 is formed on the rear end surface of the connecting bracket 22 for connecting the front bumper bracket 21 and the headlight assembly 1. When a pedestrian or the like impacts the headlight assembly 1, the crush space 221 serves as a buffer and energy absorption space for the connecting bracket 22, which is conducive to the connecting bracket 22 releasing the impact force and being easily broken, thereby providing a crush space 221 for the headlight assembly 1 and being able to reduce the injury caused when a pedestrian or the like impacts the headlight assembly 1. On the other hand, the front bumper bracket 21 is provided with a crush portion 211, so that when a pedestrian or the like impacts the front bumper or the front bumper bracket 21, the crush portion 211 serves as a buffer and energy absorption structure for the front bumper bracket 21, which is conducive to the front bumper bracket 21 releasing the impact force and being easily broken, thereby providing a crush space for the front bumper bracket 21 and being able to reduce the injury caused when a pedestrian or the like impacts the front bumper or the front bumper bracket 21. On the other hand, the crush portion 211 is provided on the upper end surface of the front bumper bracket 21, and the connecting bracket 22 is arranged relative to the crush portion 211 closer to the front end surface of the front bumper bracket 21, so that the crush space 221 serves as a primary crush structure for the headlight assembly 1, and the crush portion 211 on the front bumper bracket 21 serves as a secondary crush structure for the headlight assembly 1, thereby realizing a two-stage crush structure and being able to further improve the reduction of the injury caused when a pedestrian or the like impacts the headlight assembly. Therefore, this embodiment can improve the energy absorption and crush ability when the front end surfaces of the headlight assembly, the front bumper or the front bumper bracket, etc. are impacted, thereby reducing the injury to pedestrians or the like.
[0028] Furthermore, the headlight assembly 1 is integrally mounted on the front bumper bracket 21. During the normal driving of the vehicle, the main requirements for the front headlight assembly 1 and the front bumper bracket 21 are the supporting force in the first direction z, so as to improve the modal and stiffness and other performance of the headlight assembly 1 and the front bumper bracket 21 itself.
[0029] In some embodiments, the connecting bracket 22 includes a connected first connecting portion 222 and a second connecting portion 223. The first connecting portion 222 is configured to mount the headlight assembly 1, and the second connecting portion 223 is connected to the upper end surface of the front bumper bracket 21. Wherein, the included angle between the first connecting portion 222 and the second connecting portion 223 is defined as a, and 0 < a ≤ 90°, so as to form the crush space 221.
[0030] The included angle between the first connecting portion 222 of the connecting bracket 22 for connecting the headlight assembly 1 and the second connecting portion 223 for connecting the front bumper bracket 21 is set to be an acute angle. This not only enables the headlight assembly 1 to be installed above the front bumper bracket 21, but also forms a collapse space 221 between the rear end face of the first connecting portion 222, that is, the side face facing away from the headlight assembly 1, and the upper end face of the front bumper bracket 21. The connecting bracket 22 has a simple structure. When an impact force acts on the front end face of the first connecting portion 222, the first connecting portion 222 easily collapses and breaks towards the collapse space 221. This structure can improve the energy absorption, collapse, and fracture capabilities of the connecting bracket 22 when it is impacted, thereby reducing the harm to pedestrians and the like.
[0031] In some embodiments, the first connecting portion 222 extends along the first direction z, and the second connecting portion 223 extends along the second direction x and towards the rear end face of the bumper bracket 21; wherein, the first direction z is the arrangement direction of the front bumper bracket 21 and the connecting bracket 22, and the second direction x is perpendicular to the first direction z.
[0032] In the above manner, on the one hand, the first connecting portion 222 and the second connecting portion 223 are perpendicularly arranged, that is, the included angle between them is 90°. This enables the headlight assembly 1 and the front bumper bracket 21 to be connected through a vertical mounting structure, which can increase the volume of the collapse space 221 behind the headlight assembly 1, improve the collapse energy absorption ability, and solve the problem that the headlight assembly 1 becomes a hard point during the impact process, and can reduce the harm to the legs of pedestrians and the like. On the other hand, the vertical mounting structure can improve the connection stability between the headlight assembly 1 and the front bumper bracket 21, improve the reliability during the normal use of the vehicle, and facilitate the setting of the headlight assembly 1 above the front bumper bracket 21. On the other hand, the second connecting portion 223 extends along the second direction x and towards the rear end face of the bumper bracket 21, which can reduce the interference of the second connecting portion 223 on the connection between the headlight assembly 1 and the front bumper bracket 21, and the headlight assembly 1 can be directly set in contact with the upper end face of the front bumper bracket 21 to increase the connection stability between the two.
[0033] In other embodiments, the included angle between the first connecting portion 222 and the second connecting portion 223 can also be less than 90°, such as 85°, 80°, 75°, 70°, etc.
[0034] In some embodiments, the first connecting portion 222 and the second connecting portion 223 are integrally formed, or are connected by welding, riveting or other means.
[0035] In other embodiments, the second connecting portion can extend along the second direction and towards the front end face of the bumper bracket; or the second connecting portion can also extend along a third direction (not marked in the figure), wherein the third direction is perpendicular to the first direction and the second direction.
[0036] In some embodiments, the connecting component 2 includes a plurality of connecting brackets 22 arranged at intervals in a third direction, which is perpendicular to the first direction z and the second direction x. This not only increases the connection points between the headlight assembly 1 and the front bumper bracket 21, enhancing the connection stability therebetween, but also a collapse space 221 is formed behind each connecting bracket 22, and a gap is formed between two adjacent connecting brackets 22, which can communicate with a plurality of collapse spaces 221 to expand the total volume of the collapse space 221, thereby improving the energy absorption, collapse, and fracture capabilities of the connecting bracket 22 when impacted.
[0037] In some embodiments, the first connecting portion 222 can be connected to the headlight assembly 1 through mounting posts 224 such as studs, facilitating the improvement of the connection stability between the two and realizing the detachable connection therebetween. In other embodiments, they can also be connected by other connection methods.
[0038] In some embodiments, the connecting bracket 22 includes a plurality of second connecting portions 223, which are arranged at intervals in the third direction and are all connected to the first connecting portion 222, capable of increasing the connection stability between the first connecting portion 222 and the front bumper bracket 21.
[0039] In some embodiments, the second connecting portion 223 is triangularly arranged, and two sides of the triangle are respectively connected to the rear end face of the first connecting portion 222 and the upper end face of the front bumper bracket 21.
[0040] In other embodiments, the connecting bracket can also be other structures, such as an L-shaped or triangular connecting block, etc., and the second connecting portion can also be rectangularly arranged, etc.
[0041] In some embodiments, the front bumper bracket 21 includes an upper bracket 212 provided with an upper end face. The upper bracket 212 includes a first upper bracket portion 2121, a connecting portion 2122, and a second upper bracket portion 2123 that are connected in sequence. The first upper bracket portion 2121 is used to mount the headlight assembly 1, and the connecting portion 2122 is respectively arranged at an obtuse angle with the first upper bracket portion 2121 and the second upper bracket portion 2123 to form a collapse portion 211. In this way, the supporting force of the front bumper bracket 21 along the first direction z and the collapse ability along the second direction x can be improved.
[0042] Wherein, the first upper bracket portion 2121 and the second upper bracket portion 2123 can be arranged in parallel, and the included angles with the connecting portion 2122 are both set at 135°.
[0043] In other embodiments, the obtuse angles between the first upper bracket portion and the second upper bracket portion and the connecting portion can include inconsistencies.
[0044] In some embodiments, such asFigure 4 and Figure 5 As shown in Figure 5 , a weakening portion 2124 is provided at the connection between the connecting portion 2122 and the second upper support portion 2123; wherein, the structural strength of the weakening portion 2124 is less than the connection strength between the connecting portion 2122 and the second upper support portion 2123. By providing the weakening portion 2124 with a relatively small structural strength at the connection between the connecting portion 2122 and the second upper support portion 2123, the collapse ability of the connecting portion 2122 can be improved.
[0045] In some embodiments, the weakening portion 2124 includes a weakening groove (not labeled in the figure), and the structural thickness at the connection between the connecting portion 2122 and the second upper support portion 2123 can be reduced through the weakening groove, thereby reducing the structural strength at this connection.
[0046] Wherein, the notch of the weakening groove can face upward or downward.
[0047] In other embodiments, the weakening portion can also be realized through a through hole, or by reducing the material strength at the connection, etc. to implement the weakening portion.
[0048] In some embodiments, the second upper support portion 2123 can form a groove with an upward opening, and the weakening portion 2124 is provided at the connection between the bottom wall of the groove and the connecting portion 2122.
[0049] In some embodiments, reinforcing ribs (not labeled in the figure) can be provided on the above-mentioned bottom wall.
[0050] In some embodiments, reinforcing ribs (not labeled in the figure) are provided on the side wall of the groove of the second upper support portion 2123, and another weakening groove (not labeled in the figure) can be provided at the connection between the reinforcing ribs and the connecting portion 2122.
[0051] In some embodiments, the second upper support portion 2123 can be connected to the front bumper bracket 21 by welding, riveting, etc.
[0052] In some embodiments, the height difference between the first upper support portion 2121 and the second upper support portion 2123 is greater than 4 mm. In this way, it can be reduced that after the upper support 212 breaks, the root structure of the upper support 212 blocks the direct rearward movement of the entire upper support 212 along the second direction x, and the leg can better collapse and deform along the impact direction, that is, the second direction x, to absorb the remaining impact energy of the leg.
[0053] Wherein, the height difference between the first upper support portion 2121 and the second upper support portion 2123 being greater than 4 mm means that along the first direction z, the height difference between the first upper support portion 2121 and the second upper support portion 2123 is greater than 4 mm.
[0054] This height difference can be greater than 4 mm, 4.5 mm, 5 mm, or 5.5 mm, etc.
[0055] In some embodiments, the upper bracket 212 includes a plurality of second upper bracket portions 2123 arranged in the third direction and respectively connected to the connecting portion 2122. In this way, the collapse ability of the upper bracket 212 can be increased.
[0056] In some embodiments, the front bumper bracket 21 further includes a front bracket 213 located on the front end face and connected to the upper bracket 212, and the front bracket 213 has a deformation ability.
[0057] The headlight assembly 1 is integrally mounted on the front bumper bracket 21. During normal driving of the vehicle, the main requirements for the front headlight assembly 1 and the front bumper bracket 21 are the supporting force in the first direction z to improve the modal and stiffness performance of the headlight assembly 1 and the front bumper bracket 21 itself; during a collision, in the first deformation stage when a pedestrian's leg contacts the front bumper bracket 21, the leg contacts the front bracket 213 of the front bumper bracket 21, that is, the soft area b1 of the front bumper bracket 21. This soft area b1 can effectively support the front bumper skin, ensuring the surface stiffness and modal performance of the front bumper bracket 21. At the same time, the leg can drive the soft area b1 to move backward along the second direction x, and the soft area b1 deforms and absorbs energy to absorb the impact energy of the leg; as the leg impact drives the soft area b1 to move backward, in the second stage of deformation, the leg shape impacts the headlight assembly 1, that is, the first hard point b2. The headlight assembly 1 is integrally mounted on the front bumper bracket 21 by a 90° vertical mounting method. During the leg impact process, the impact force along the second direction x causes the mounting bracket of the headlight assembly 1 and the connecting bracket 22 to break and fail under the action of shear force, and the headlight assembly 1 moves backward to absorb the impact energy of the leg; after the connecting bracket 22 fails, the leg continues to move backward and contacts the second hard point b3 during the leg impact process, that is, the upper bracket 212 of the front bumper bracket 21. The upper bracket 212 is designed at 45°, that is, the induced structure of the above-mentioned obtuse angle 135°. And at the root of each upper bracket 212, there is a weakening line structure with a basic design width of 1.2 mm, such as a weakening groove. During the leg impact process, the upper bracket 212 breaks and fails at the root of the weakening line, and it is ensured that the height difference of the upper and lower end brackets of the 45° induced structure along the first direction z is greater than 5 mm, reducing the blockage of the root structure of the upper bracket 212 on the direct backward movement of the entire upper bracket along the second direction x after the upper bracket 212 breaks, so that the leg can collapse and deform better along the impact direction and absorb the remaining impact energy of the leg; since during the normal driving process of the vehicle and during the process when the front bumper or the front bumper bracket 21 of the vehicle is impacted by a leg, the front bumper bracket 21 can provide effective support, the drooping mode of the front bumper bracket 21 or the front bumper and the product performance of the headlight assembly itself can be ensured.
[0058] Through the collapse deformation in the above three stages, the collapse space during the collision process of the pedestrian's leg and the like can be increased, the performance of the leg can be improved. At the same time, the soft area b1 structure of the front bumper bracket 21 can effectively support the front bumper skin, improving the surface stiffness and modal performance of the front bumper bracket 21 or the front bumper. Moreover, the main weakening and collapse direction of the front bumper bracket 21 is the second direction x, with less weakening of the front bumper bracket 21 along the first direction z, effectively ensuring the performance requirements such as the droop and modal of the front bumper bracket 21 or the front bumper. Through this embodiment, the requirements of the headlight assembly and the performance of the front bumper bracket 21 or the front bumper product itself and the pedestrian protection performance can be effectively balanced.
[0059] The present application further proposes a vehicle frame structure, which includes the above-mentioned connection component 2, headlight assembly 1 and front bumper. For the structure of the connection component 2 and the connection structure between the connection component 2 and the headlight assembly 1 and the front bumper, reference can be made to the above embodiments, which will not be elaborated here.
[0060] The present application further proposes a vehicle, which includes the above-mentioned vehicle frame structure or the above-mentioned connection component. For the specific structure of the vehicle frame structure and the specific structure of the connection component, reference can be made to the above embodiments, which will not be elaborated here.
[0061] The connection component provided by the present application is used to connect the front bumper of a vehicle and a headlight assembly. The connection component includes a front bumper bracket and a connection bracket. Among them, the front end face of the front bumper bracket is configured to mount the front bumper; the connection bracket is connected to the upper end face of the front bumper bracket, the front end face of the connection bracket is configured to mount the headlight assembly, and a collapse space is formed on the rear end face of the connection bracket; a collapse portion is provided on the upper end face of the front bumper bracket, and the connection bracket is arranged closer to the front end face of the front bumper bracket relative to the collapse portion. In this way, on the one hand, a collapse space is formed on the rear end face of the connection bracket for connecting the front bumper bracket and the headlight assembly. When a pedestrian or the like impacts the headlight assembly, the collapse space serves as a buffer and energy absorption space for the connection bracket, which is conducive to the connection bracket releasing the impact force and being easily broken, thereby providing a collapse space for the headlight assembly and being able to reduce the injury caused when a pedestrian or the like impacts the headlight assembly. On the other hand, the front bumper bracket is provided with a collapse portion, so that when a pedestrian or the like impacts the front bumper or the front bumper bracket, the collapse portion serves as a buffer and energy absorption structure for the front bumper bracket, which is conducive to the front bumper bracket releasing the impact force and being easily broken, thereby providing a collapse space for the front bumper bracket and being able to reduce the injury caused when a pedestrian or the like impacts the front bumper or the front bumper bracket. On the further hand, the collapse portion is provided on the upper end face of the front bumper bracket, and the connection bracket is arranged closer to the front end face of the front bumper bracket relative to the collapse portion, so that the collapse space serves as a primary collapse structure for the headlight assembly, and the collapse portion on the front bumper bracket serves as a secondary collapse structure for the headlight assembly, thereby realizing a two-stage collapse structure and being able to further improve the reduction of the injury caused when a pedestrian or the like impacts the headlight assembly. Therefore, the present application can improve the energy absorption, collapse, and fracture capabilities of the front end faces of the headlight assembly, the front bumper, or the front bumper bracket, etc. when being impacted, thereby reducing the injury to pedestrians or the like.
[0062] Furthermore, in order to balance the performance requirements of the headlight assembly itself and the pedestrian protection requirements at the same time, by mounting the headlight assembly on the front bumper bracket and developing a design method that is conducive to releasing space and being easily broken, a sufficient collapse space is given to the headlight assembly, and the respective performance requirements are met at the same time. The headlight assembly of the present application is integrated onto the front bumper bracket, with a simple structure. It abandons the structural form in which the headlight assembly has its own mounting bracket different from the traditional method and is mounted on the front end frame through bolts, effectively reducing the weight of the headlight assembly and the cost; the connection bracket of the front bumper bracket and the headlight assembly can effectively and stably achieve collapse in the second direction, which is conducive to the protection of the legs; the weakening structures of the connection bracket and the front bumper bracket in the present application are all in a manner that is easily collapsible in the second direction and do not affect the first direction. Therefore, sufficient support in the first direction can be generated under the working conditions of normal vehicle driving and being impacted by the legs, ensuring the performance such as the drooping and mode of the headlight assembly, the front bumper, and their brackets.
[0063] Furthermore, the present application can adjust the height and matching relationship between the connecting bracket and the front bumper bracket according to the height of the vehicle and the different leg impact energies, taking into account the performance requirements of pedestrian protection and the front bumper itself to the greatest extent possible.
[0064] The above description is only an implementation manner of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
