[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] like Figure 1 As shown, a vehicle lamp travel protection bracket comprises a bracket body 1, one end of the bracket body 1 is connected to the vehicle lamp mounting foot 2, the other end of the bracket body 1 is connected to the vehicle body, and the middle part of the bracket body 1 has a weakened structure 4.

[0026] The weakening structure 4 is a plate-like structure, which refers to a structure with a relatively small thickness and a large plane area perpendicular to the thickness direction. When the utility model is in use, the thickness direction is the vertical direction. Figure 2 and Figure 3 The weakened structure 4 shown is a rectangular plate, and a plurality of V-shaped grooves 5 are provided on the upper surface and front and rear side surfaces of the weakened structure 4. A weakened hole that passes through from top to bottom is provided in the V-shaped groove 5 on the upper surface of each weakened structure 4, and the distance between the bottom surface of the V-shaped groove 5 and the bottom surface of the weakened structure 4 is greater than or equal to 1 mm.

[0027] The V-shaped groove 5 is provided to concentrate stress at this place when the headlight 3 is hit, so that cracks are generated in the bracket body 1 at the V-shaped groove 5. The V-shaped groove 5 is provided in three directions. No matter from which direction the headlight 3 is hit, stress concentration can be achieved through the V-shaped groove 5 in the corresponding direction. The weakening hole is provided to reduce the solid area of ​​the middle structure of the weakening structure 4, which is conducive to further cracking. The distance between the bottom surface of the V-shaped groove 5 and the bottom surface of the weakening structure 4 is the minimum thickness of the weakening structure 4. If this value is too small, the strength of the bracket body 1 will be too poor, and the ability to withstand vibration and impact will be weak.

[0028] Through the above definition, the safety bracket can meet the daily use requirements of the car. At the same time, when a pedestrian collides with the headlight 3, it can also break quickly due to the effect of stress concentration to protect the pedestrian.

[0029] Preferably, the V-shaped grooves 5 are arranged in an array along the length direction of the weakened structure 4, and the weakened holes include long holes 6 and short holes 7, the cross-sectional length a of the long holes 6 is greater than the cross-sectional length b of the short holes 7, and the long holes 6 and the short holes 7 are arranged alternately along the length direction of the weakened structure 4. The staggered arrangement weakens the structural strength to the greatest extent while ensuring the normal driving of the car, which is conducive to the rapid fracture of the weakened structure 4 during a collision. The long holes 6 and the short holes 7 can be located in the same V-shaped groove 5.

[0030] In order to ensure the beautiful structure, the long holes 6 and the short holes 7 in the utility model are respectively located in two adjacent V-shaped grooves 5, and the number of the long holes 6 in each V-shaped groove 5 is less than the number of the short holes 7 in each V-shaped groove 5. Figure 2 As shown, two short holes 7 are provided in the V-shaped groove 5, and one long hole 6 is provided in the V-shaped groove 5, which are regularly and alternately arranged in sequence, and the structure is neat and regular.

[0031] Taking into account the structural strength and breakability requirements, the ratio of the cross-sectional length b of the short hole 7 to the width d of the weakened structure 4 in this embodiment is 1 / 4 to 1 / 3, and the ratio of the cross-sectional length a of the long hole 6 to the width d of the weakened structure 4 is 1 / 2 to 2 / 3.

[0032] If the opening angle of the V-shaped groove 5 is too small or too large, the stress concentration surface area will be flat and the stress concentration effect cannot be achieved. Therefore, as a preferred embodiment, the opening angle of the V-shaped groove 5 is 90°~150°.

[0033] In a further design, an energy absorbing structure 8 is further connected between the headlight mounting foot 2 and the vehicle body. The energy absorbing structure 8 is located at the bottom of the weakened structure 4 and is arranged in close contact with the weakened structure 4. The deformable characteristics of the energy absorbing structure 8 can cause the weakened structure 4 to be disconnected by force when a pedestrian collides with the headlight 3, and the energy absorbing structure 8 itself will not be damaged. Therefore, after the weakened structure 4 is disconnected, the headlight 3 can be flexibly connected to the vehicle body through the energy absorbing structure 8, which can prevent a hard collision with a pedestrian and prevent the headlight 3 from falling. In addition, during normal driving of the vehicle, the energy absorbing structure 8 can also support the weakened structure 4 and improve its anti-bumping ability. The lower surface of the weakened structure 4 is preferably a plane (such as Figure 4 as shown).

[0034] The energy absorbing structure 8 may be a material that can be deformed by force, such as foam, rubber block or spring.

[0035] In terms of installation, the bracket body 1, the headlight mounting foot 2 and the vehicle body can be connected by welding or bolts. For easy disassembly, the bracket body 1 is preferably provided with a first mounting hole 9 connected to the headlight mounting foot 2 and a second mounting hole 10 connected to the vehicle body. The first mounting hole 9 and / or the second mounting hole 10 are waist-shaped holes or holes with a diameter larger than the connecting piece. When waist-shaped holes are used, the length direction of the waist-shaped holes is the same as the length direction of the bracket body 1. This design can adjust the installation distance according to different assembly distances to achieve matching adjustment of the headlight 3 and the vehicle front-end module. Figure 1 and Figure 2 As shown, the first mounting hole 9 and the second mounting hole 10 are both round holes, and an adjustable nut 12 is used at the first mounting hole 9 to fix the bracket body 1 and the lamp mounting foot 2, that is, the size of the first mounting hole 9 is larger than the diameter of the adjustable nut 12, and the second mounting hole 10 uses a fixed nut to fix the bracket body 1 and the vehicle body, that is, the size of the second mounting hole 10 just matches the diameter of the fixed nut.

[0036] The two ends of the energy absorbing structure 8 can be fixed by pasting. The energy absorbing structure 8 can be directly fixed to the headlight 3 and the vehicle body. After the weakening structure 4 is broken, the bracket body 1 is divided into two sections, which are respectively connected to the headlight mounting foot 2 and the vehicle body. Therefore, the energy absorbing structure 8 can also be fixed to these two sections. In the preferred embodiment of the utility model, a side panel 11 is provided at one end of the bracket body 1 connected to the vehicle body, and one end of the energy absorbing structure 8 is pasted between the two side panels 11, and the other end is pasted and fixed to the headlight mounting foot 2. The design of the side panel 11 can increase the fixing area of ​​the energy absorbing structure 8, improve the fixing effect, and prevent the energy absorbing structure 8 from falling off during vehicle driving.
