Description

Technical Field

[0001] This utility model relates to the field of mounting bracket technology, specifically a lightweight high-strength headlight mounting bracket for vehicles. Background Technology

[0002] In the automotive manufacturing industry, headlights are an important component for vehicle lighting and safe driving. The structural design and performance of their mounting brackets directly affect the stability and safety of headlight use. As the automotive industry develops towards lightweighting and intelligence, the requirements for headlight mounting brackets are becoming increasingly stringent.

[0003] Currently, most automotive headlight mounting brackets use ordinary plastic materials to reduce costs. While this reduces weight, it fails to meet the requirements for high strength and durability. On the other hand, some brackets using all-metal materials, although ensuring strength, increase the overall vehicle weight, which is detrimental to energy conservation, emission reduction, and vehicle performance improvement. Furthermore, automotive headlight mounting brackets are mostly fixed to the vehicle frame using bolts. During vehicle operation, factors such as road bumps and engine vibrations cause the bolts to be in a state of high-frequency vibration for a long time, making them extremely prone to stripping and loosening. This leads to instability in headlight installation. To address these issues, the inventor proposes a lightweight, high-strength automotive headlight mounting bracket. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a lightweight high-strength headlight mounting bracket for vehicles, comprising a mounting bracket body and a lamp body frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. In this utility model, the non-critical structural materials such as the mounting plate, auxiliary frame one and auxiliary frame two are made of glass fiber reinforced plastic, while the main structure such as the mounting bracket body and the lamp body frame are made of high-strength carbon fiber composite material.

[0022] A spring 26 is fixedly connected to the center of the top of the sliding plate 23, and the top of the spring 26 is fixedly connected to the inner wall of the inner cavity 22.

[0023] By adopting the above technical solution, the spring 26 is set so that it can still achieve the effect of reset after being inserted into the slot 3.

[0024] An auxiliary rod 24 is slidably connected to the back end of the lamp frame 2 near the inner cavity 22, and the side end of the auxiliary rod 24 is fixedly connected to the sliding plate 23. An auxiliary rod 33 is slidably connected to the back end of the mounting bracket body 1 near the inner cavity 31, and the side end of the auxiliary rod 33 is fixedly connected to the sliding plate 32.

[0025] By adopting the above technical solution, by moving the auxiliary rod 24, the fixedly connected sliding plate 23 can be raised, and by moving the auxiliary rod 33, the fixedly connected sliding plate 32 can be raised.

[0026] An arc-shaped groove 37 is provided on the outer ring of the connecting shaft 35 near the center, and a U-shaped groove 38 is provided on the center of the side of the sliding plate 32 away from the auxiliary rod 33.

[0027] By adopting the above technical solution, an arc-shaped groove 37 is opened on the outer ring of the connecting shaft 35 in order to cooperate with the sliding shaft 42 to achieve the effect of limiting the connecting shaft 35.

[0028] An installation cylinder 4 is fixedly connected to the center of the inner wall on one side of the inner cavity 31, and the installation cylinder 4 and the U-shaped groove 38 are at the same level. A sliding shaft 42 is slidably inserted into the side end of the installation cylinder 4 near the connecting shaft 35.

[0030] A spring 41 is fixedly connected to the side end of the sliding shaft 42, and the other end of the spring 41 is fixedly connected to the inner wall of the mounting cylinder 4.

[0031] By adopting the above technical solution, a spring 41 is provided on the side of the sliding shaft 42 in order to achieve the effect of resetting the sliding shaft 42.

[0032] A ball bearing 43 is provided on the side end of the sliding shaft 42 near the connecting shaft 35.

[0033] By adopting the above technical solution, the ball bearing 43 is set on the side of the sliding shaft 42 so as to cooperate with the arc groove 37 to achieve the effect of limiting the connecting shaft 35.

[0034] Mounting bracket body 1 is symmetrically fixedly connected to the upper and lower ends and near the center of the mounting bracket body 1. Auxiliary bracket 12 is fixedly connected to the side end of the mounting bracket body 1.

[0035] By adopting the above technical solution, the mounting plate 11 is used to fix the mounting bracket body 1, the auxiliary frame 12 is used to fix auxiliary components such as heat sinks, and the auxiliary frame 2 13 is used to fix auxiliary components such as wire harnesses. The mounting plate 11, auxiliary frame 12 and auxiliary frame 2 13 are non-critical parts and can be made of lightweight materials (glass fiber reinforced plastic). The mounting bracket body 1 and the lamp frame 2 are the main support structures and can be made of high-strength materials (carbon fiber composite materials).

[0036] Working principle: When using this device, firstly, the auxiliary rod 24 and auxiliary rod 33 are pushed upwards, which moves the fixedly connected shaft 34 and shaft 25 upwards. Then, the lamp frame 2 can be placed inside the mounting bracket body 1. Then, the force on the auxiliary rod 24 and auxiliary rod 33 is released, which causes the sliding plate 23 to descend under the action of the spring 26, so that the shaft 25 can be inserted into the slot 3. In addition, the sliding plate 32 will drive the shaft 34 to descend, so that the shaft 34 can be inserted into the slot 21. This completes the limiting work of the lamp frame 2. After the sliding plate 32 descends, the ball 43 will move to the arc groove 37 to complete the limiting work of the connecting shaft 35. This can enhance the limiting effect of the lamp frame 2 and avoid the stripping of the bolt due to vibration when using the bolt to limit the lamp frame 2.

[0037] In addition, non-critical structural components such as mounting plate 11, auxiliary frame 12, and auxiliary frame 2 13 can be made of glass fiber reinforced plastic, while the main structure such as mounting bracket body 1 and lamp body frame 2 can be made of high-strength carbon fiber composite material. This can reduce the area of ​​plastic material used in the structural design while maintaining the strength of the mounting bracket.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
