Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to an automotive lighting system with an impact protection structure. Background Technology

[0002] In the automotive industry, headlights are an important component of vehicles, undertaking the key functions of illumination and signal indication. With the continuous advancement of automotive technology and the increasing demands of consumers for vehicle safety and comfort, the design of automotive headlights has become increasingly complex and sophisticated. However, in actual use, automotive headlights, especially those located at the front of the vehicle, often face potential impact risks from road obstacles, pedestrian collisions, and even minor traffic accidents. Headlights are easily damaged after being impacted, causing them to fail to perform their normal illumination and signal indication functions.

[0003] Existing car headlights have a simple structure and lack anti-collision features. In the event of a vehicle accident, the headlights cannot be protected and are easily damaged, which can lead to increased maintenance costs.

[0004] The existing patent (publication number: CN217082400U) discloses an emergency accident protection car light with an anti-collision mechanism. This utility model consists of a housing, a reinforcing layer, a lens, a car light body, a protective ring assembly, a fixed plate, a base plate, a connecting block assembly, an energy-absorbing sleeve, a baffle, a protective lens, and the energy-absorbing ring assembly working together to provide protection for the car light. This solves the problem that traditional car lights have a simple structure, lack an anti-collision structure, and cannot protect the car light in the event of a vehicle accident, making the car light easily damaged and increasing maintenance costs.

[0005] To address the aforementioned issues, existing patents have provided solutions, but these solutions cannot reduce the impact force on the car headlights, nor can they provide repositioning and protection for the light-emitting body when the headlights are impacted. When existing car headlights are damaged by impact, fragments of the lamp cover and lamp cap can easily impact the light-emitting body, causing damage to the headlight.

[0006] Therefore, a car headlight with an impact protection structure is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a car headlight with an impact protection structure, which can solve the problems of existing car headlights that cannot reduce the impact force on the car headlight and cannot move and store the light-emitting body for protection when the car headlight is impacted.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a car headlight with an impact protection structure, comprising a light-emitting body, a mounting cylinder provided on the side wall of the light-emitting body, a mounting protective cylinder provided on the side wall of the mounting cylinder, a fixed lamp cover fixedly connected to the side wall of the mounting protective cylinder, a protective mechanism provided on the side wall of the fixed lamp cover, and an adjustable fixing mechanism provided at one end of the mounting protective cylinder;

[0009] The protective mechanism includes a buffer cover movably mounted on the side wall of the fixed lampshade. A lamp cover is threaded onto the side wall of the buffer cover. Three buffer grooves are provided on the side wall of the mounting protective cylinder. A buffer block is fixedly connected to the inner wall of the buffer cover. A retaining ring is bolted to the side wall of the fixed lampshade. A buffer spring is provided between the buffer block and the retaining ring. Three push rods are fixedly connected to the side wall of the buffer cover. The other end of each push rod is fixedly connected to the mounting cylinder. A movable groove is provided on the side wall of the mounting protective cylinder to movably connect with the push rods.

[0010] Preferably, the adjustable fixing mechanism includes a mounting plate fixedly connected to one end of the mounting protective cylinder. Three mounting blocks are movably arranged on the side wall of the mounting plate. Mounting grooves are formed on the side wall of the mounting blocks. Limiting protrusions are fixedly connected to the inner wall of the mounting blocks. Limiting grooves are formed on the side wall of the mounting plate. The limiting protrusions are movably connected to the limiting grooves.

[0011] Preferably, three threaded tubes are fixedly connected to the side wall of the retaining ring. The threaded tubes are located at the center of the buffer groove. An adjusting screw is threadedly connected to the middle of the threaded tube. An adjusting head is fixedly connected to one end of the adjusting screw. The side wall of the adjusting head is in contact with the buffer spring.

[0012] Preferably, a guide rod is fixedly connected to the side wall of the buffer block, a guide cylinder is fixedly connected to the side wall of the adjusting head, the guide rod and the guide cylinder are movably connected, and the buffer spring is sleeved on the side wall of the guide rod and the guide cylinder.

[0013] Preferably, a limiting protective ring is provided on the side wall of the mounting protective cylinder, the limiting protective ring is engaged with the light-emitting lamp body, and the side wall of the limiting protective ring is in contact with the mounting cylinder.

[0014] Preferably, a limiting groove is provided on the side wall of the fixed lamp cover, and a limiting ring is provided on the inner wall of the buffer cover, with the limiting ring being movably connected to the limiting groove.

[0015] Preferably, the light-emitting body includes a light-emitting core, one end of which is provided with a circuit board, one end of which is provided with a heat sink, and one end of which is provided with a connecting wire.

[0016] Preferably, heat dissipation grooves are provided on the side walls of both the mounting cylinder and the mounting protective cylinder, and the positions of the heat dissipation grooves on the side walls of the mounting cylinder and the mounting protective cylinder coincide.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application incorporates a protective mechanism. When the headlight encounters an external impact, the buffer cover is subjected to pressure, pushing the buffer block on its inner wall towards the fixed headlight cover. The buffer spring between the buffer block and the retaining ring absorbs and disperses the impact energy through its elastic deformation, effectively reducing the impact force transmitted to the headlight body. The push rod on the side wall of the buffer cover slides in the movable groove of the mounting protective cylinder. At this time, the headlight body and the mounting cylinder are moved to the center position of the mounting protective cylinder, effectively moving and storing the headlight body and the mounting cylinder for protection. This effectively avoids the risk of the headlight body being damaged by debris impacts and significantly reduces the risk of damage to the headlight body.

[0019] 2. This application features an adjustable fixing mechanism. During this process, the mounting block is movably connected to the limiting groove on the mounting plate via a limiting protrusion. This not only ensures the stable installation of the protective cylinder but also allows for fine-tuning within a certain range, making the installation of the vehicle light more convenient to adapt to different installation needs and improving the versatility and practicality of the vehicle light.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 5 This utility model provides a technical solution:

[0030] A car headlight with an impact protection structure includes a light-emitting body 1, a mounting cylinder 2 on the side wall of the light-emitting body 1, a mounting protective cylinder 3 on the side wall of the mounting cylinder 2, a fixed lamp cover 4 fixedly connected to the side wall of the mounting protective cylinder 3, a protective mechanism 5 on the side wall of the fixed lamp cover 4, and an adjustable fixing mechanism 6 at one end of the mounting protective cylinder 3.

[0031] The protective mechanism 5 includes a buffer cover 51 movably mounted on the side wall of the fixed lamp cover 4. A lamp cover 52 is threaded onto the side wall of the buffer cover 51. Three buffer grooves 53 are provided on the side wall of the mounting protective cylinder 3. A buffer block 54 is fixedly connected to the inner wall of the buffer cover 51. A retaining ring 55 is bolted to the side wall of the fixed lamp cover 4. A buffer spring 56 is provided between the buffer block 54 and the retaining ring 55. Three push rods 57 are fixedly connected to the side wall of the buffer cover 51. The other end of the push rod 57 is fixedly connected to the mounting cylinder 2. A movable groove 58 is provided on the side wall of the mounting protective cylinder 3, which is movably connected to the push rod 57.

[0032] Specifically, such as Figure 3 As shown, three threaded tubes 7 are fixedly connected to the side wall of the retaining ring 55. The threaded tubes 7 are located at the center of the buffer groove 53. An adjusting screw 8 is threadedly connected to the middle of the threaded tube 7. An adjusting head 9 is fixedly connected to one end of the adjusting screw 8. The side wall of the adjusting head 9 is in contact with the buffer spring 56.

[0033] Specifically, such as Figure 3 As shown, a guide rod 10 is fixedly connected to the side wall of the buffer block 54, and a guide cylinder 11 is fixedly connected to the side wall of the adjusting head 9. The guide rod 10 and the guide cylinder 11 are movably connected, and the buffer spring 56 is sleeved on the side walls of the guide rod 10 and the guide cylinder 11.

[0034] Specifically, such as Figure 2 As shown, a limiting protective ring 12 is provided on the side wall of the mounting protective cylinder 3. The limiting protective ring 12 is engaged with the light lamp body 1, and the side wall of the limiting protective ring 12 is in contact with the mounting cylinder 2.

[0035] Specifically, such as Figure 5 As shown, a limiting groove 13 is provided on the side wall of the fixed lamp cover 4, and a limiting ring 14 is provided on the inner wall of the buffer cover 51. The limiting ring 14 is movably connected to the limiting groove 13.

[0036] Specifically, such as Figure 3 As shown, the light-emitting lamp body 1 includes a light-emitting lamp core 15, a circuit board 16 is provided at one end of the light-emitting lamp core 15, a heat sink 17 is provided at one end of the circuit board 16, and a connecting wire 18 is provided at one end of the heat sink 17.

[0037] Specifically, such as Figure 2 As shown, heat dissipation grooves 19 are provided on the side walls of both the mounting cylinder 2 and the mounting protective cylinder 3, and the positions of the heat dissipation grooves 19 on the side walls of the mounting cylinder 2 and the mounting protective cylinder 3 overlap.

[0038] In use, the lamp body 1 serves as the core component of the vehicle lamp. A protective mounting sleeve 3 is installed on the outer side of the mounting cylinder 2, enhancing the protection of the lamp body 1. The fixed lamp cover 4 provides the first line of external protection for the vehicle lamp. The lamp cover 52 is secured by a threaded connection, facilitating daily maintenance and replacement. When the vehicle lamp encounters an external impact, the buffer cover 51 is the first to be impacted, pushing the buffer block 54 on its inner wall towards the fixed lamp cover 4. At this time, the buffer spring 56 between the buffer block 54 and the retaining ring 55 absorbs and disperses the impact energy through its elastic deformation, effectively reducing the impact force transmitted to the lamp body 1. The push rod 57 on the side wall of the buffer cover 51 slides within the movable groove 58 of the protective mounting sleeve 3. At this point, the lamp body 1 and the mounting cylinder 2 are moved to the center position of the protective mounting sleeve 3, thus protecting the lamp body 1 and the mounting cylinder 2. Effective mobile storage and protection effectively avoids the risk of damage to the light-emitting lamp body 1 from impacts by debris. The cooperation of the threaded tube 7, adjusting screw 8, and adjusting head 9 on the side wall of the retaining ring 55 allows the preload of the buffer spring 56 to be adjusted as needed. By rotating the adjusting head 9, the length of the adjusting screw 8 extending into the threaded tube 7 can be changed, thereby adjusting the compression degree of the buffer spring 56 and achieving fine control of the buffering effect. The guide rod 10 on the buffer block 54 is movably connected to the guide cylinder 11 on the adjusting head 9, ensuring the stability of the buffering process and preventing the lateral displacement of the buffer block 54. The limiting protection ring 12 provides limiting protection for the light-emitting lamp body. The composition of the light-emitting lamp core 15, circuit board 16, heat sink 17, and connecting wire 18 inside the light-emitting lamp body 1 ensures the efficient operation and good heat dissipation of the vehicle lamp.

[0039] Specifically, such as Figure 2 As shown, the adjustable fixing mechanism 6 includes a mounting plate 61 fixedly connected to one end of the mounting protective cylinder 3. Three mounting blocks 62 are movably arranged on the side wall of the mounting plate 61. Mounting grooves 63 are opened on the side wall of the mounting blocks 62. Limiting protrusions 64 are fixedly connected to the inner wall of the mounting blocks 62. Limiting grooves 65 are opened on the side wall of the mounting plate 61. The limiting protrusions 64 and the limiting grooves 65 are movably connected.

[0040] In use, the adjustable fixing mechanism 6 mainly consists of components such as mounting plate 61, mounting block 62, mounting groove 63, limiting protrusion 64, and limiting groove 65. The mounting block 62 moves on the mounting plate 61, allowing the mounting block 62 to be finely adjusted within a certain range. The mounting groove 63 on the side wall of the mounting block 62 is used to connect with the vehicle body or other fixed structures to ensure that the headlight can be securely installed on the vehicle. At the same time, the limiting protrusion 64 is fixedly connected to the inner wall of the mounting block 62. These limiting protrusions 64 cooperate with the limiting groove 65 on the side wall of the mounting plate 61 to realize the movable connection of the mounting block 62 on the mounting plate 61 and limit its range of movement, preventing the mounting block 62 from falling off or misaligning during the installation process.

[0041] By adopting the above technical solution, the problems of existing car lights being unable to reduce the impact force on the car lights and being unable to move and store the light-emitting body 1 for protection when the car lights are impacted are solved.

[0042] Working principle: When in use, the entire unit is first installed and fixed by the cooperation of the mounting block 62, mounting groove 63 and mounting plate 61. When the headlight is hit by an external impact, the buffer cover 51 is impacted first, pushing the buffer block 54 on its inner wall to move towards the fixed cover 4. At this time, the buffer spring 56 between the buffer block 54 and the retaining ring 55 absorbs and disperses the impact energy through its elastic deformation, effectively reducing the impact force transmitted to the light-emitting lamp body 1. The push rod 57 on the side wall of the buffer cover 51 slides in the movable groove 58 of the mounting protective cylinder 3. At this time, the light-emitting lamp body 1 and the mounting cylinder 2 are moved to the center position of the mounting protective cylinder 3, effectively moving and storing the light-emitting lamp body 1 and the mounting cylinder 2 for protection, effectively avoiding the risk of the light-emitting lamp body 1 being damaged by fragments.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
