Problems solved by technology

In the prior art, the headlights and the body of the car are mostly directly fixed and connected by bolts. This connection leads to a frontal or side frontal collision even when the car is traveling at a low speed. Although the impact force is not large, the headlights are easily damaged. After an accident, it is often necessary to send it to a repair shop for overhaul
With the rapid development of the automobile industry in recent years, the replacement of headlights is also very rapid. Many headlights are expensive and the maintenance cost is high.

Embodiment 1

[0030] like Figures 1 to 4 As shown, Embodiment 1 of the present invention provides a headlight protection device. The headlight protection device includes a sliding connection part 1 , a pressing part 2 and a fastener 3 . There are prefabricated holes (not shown) on the headlight 5, and one end of the sliding connection part 1 is provided with a mounting hole 13. During installation, the connecting bolt 6 is passed through the prefabricated hole and the installation hole 13, and after tightening, the sliding connection part 1 is connected to the installation hole 13. The headlights 5 are fixedly connected, so that the two become a rigid whole, and the bolt connection is adopted here to facilitate the replacement of the sliding connecting part 1 after the headlights are impacted. In another embodiment of the present invention, a welding connection method is adopted here, which can avoid loosening of the connection between the headlight 5 and the sliding connection portion 1 ...

Embodiment 2

[0036] The difference between this embodiment and Embodiment 1 mainly lies in the shape of the connection port 11 and the distribution of the raised bars 12 . In this embodiment, as Image 6 As shown, the shape of the connection port 11 is a right-angled triangle, and the three inner corners of the right-angled triangle are all rounded, so as to eliminate the concentrated stress near each inner corner and prolong the service life of the sliding connection part 1; the fastener 3 passes through the connection port 11. The side of the smaller acute angle is connected to the pressing part 2 and the body 4 , the longer right-angled side of the connection port 11 is parallel to the vehicle's straight-forward direction, and the other right-angled side is perpendicular to the vehicle's straight-forward direction. In order to have enough space for the sliding connection part 1 to be displaced relative to the body body 4 when the headlight 5 is hit by a frontal or side-forward impact, t...

Embodiment 3

[0040] The difference between this embodiment and Embodiment 1 mainly lies in the shape of the connection port 11 and the distribution of the raised bars 12 . In this embodiment, as Figure 8 As shown, the shape of the connection port 11 is an isosceles trapezoid, and the smaller acute angle of the isosceles trapezoid is 30°˜70°. In a preferred embodiment of the present invention, the smaller acute angle of the isosceles trapezoid is 60°. The four inner corners of the isosceles trapezoid are all rounded to eliminate the concentrated stress near each inner corner and prolong the service life of the sliding connection part 1; the two parallel sides of the connection port 11 are perpendicular to the direction of the car going straight, among which the longer The parallel side is arranged on the side close to the mounting hole 13 . The fastener 3 is connected to the pressing part 2 and the body body 4 through the side of the smaller parallel side of the connecting port 1, so that...

Abstract

The invention discloses a head lamp protection device and a car. The head lamp protection device comprises a sliding connecting part (1), and a fastening part (3), one end of the sliding connecting part (1) is fixedly connected with a head lamp (5), the other end of the sliding connecting part (1) is connected with a car body (4) through the fastening part (3), under the external force effect, the sliding connecting part (1) can slide relative to the car body (4), the head lamp protection device is arranged between the head lamp (5) and the car body (4), under the condition that the front face or the side front portion of the car is in collision, when the impact force is larger than the sum of the friction force between the sliding connecting part (1) and the car body (4) and the friction force between the sliding connecting part (1) and the fastening part (3), the head lamp (5) at least can move in the direction opposite to the car straight walking direction to avoid collision, and under the condition that the impact force is not too large, the damage of the head lamp can be effectively reduced or avoided.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a headlight protection device. Background technique [0002] The headlight of a car can illuminate the front view for the driver to drive the vehicle safely. It is an indispensable and important part of the car. Especially in the process of driving at night, the headlight is a key component to ensure driving safety. Protection is very necessary. When a serious frontal or side-front collision occurs, the damage of the headlights is almost inevitable. Therefore, only how to reduce or avoid the damage of the headlights in a low-speed frontal or side-front collision is considered here. In the prior art, most of the headlights and the body are directly connected by bolts. This connection method leads to a frontal or side-to-front collision even when the car is traveling at a low speed. Although the impact force is not large, the headlights are easily damaged. , After an accident, it is oft...
