Description

Technical Field

[0001] This utility model relates to the field of LED lighting equipment technology, and in particular to an anti-collision buffer device for LED lighting lamps. Background Technology

[0002] In the lighting field, LED lights are widely used due to their advantages such as energy saving, high efficiency and long life. However, in actual use scenarios, such as road lighting and construction site lighting, LED lights face various accidental collision risks such as vehicle collisions and construction collisions. Therefore, an LED lighting anti-collision buffer device is needed.

[0003] Regarding existing related technologies, the inventors believe that the following defects often exist: Most existing LED lights lack effective anti-collision buffer structures. Once they are hit, the outer shell, internal circuits and light-emitting elements of the lamps are easily damaged, which not only affects the lighting function, but also greatly increases maintenance costs and replacement frequency. Although some lamps have simple protective structures, the buffering effect is not good and cannot fully absorb the collision energy, thereby reducing the lifespan of the lamps. Utility Model Content

[0004] The technical problem to be solved by this utility model is that LED lights are easily damaged when they collide with objects in the prior art. To address this, we propose an anti-collision buffer device for LED lights.

[0005] To achieve the above objectives, this application adopts the following technical solution: an LED lighting anti-collision buffer device, comprising an outer shell, an inner shell, a buffer assembly, and a connecting assembly: the outer shell is a hollow cylinder with openings at the top and bottom, and a guide groove on the inner wall of the outer shell; the inner shell is a hollow cylinder with an outer diameter smaller than the inner diameter of the outer shell, and a guide block that mates with the guide groove on the outer wall of the inner shell; the inner shell is used to mount the main body of the LED lighting lamp; the buffer assembly includes multiple buffer springs and buffer pads; one end of each buffer spring is fixed to the inner wall of the outer shell, and the other end of each buffer spring is connected to the outer wall of the inner shell; the multiple buffer springs are evenly distributed between the inner shell and the outer shell; the buffer pads are respectively disposed on the top, bottom, and side walls of the inner shell opposite to the outer shell; the connecting assembly includes a fixing flange and connecting bolts; the fixing flange is disposed at the bottom of the outer shell, and a connecting hole is provided on the fixing flange; the fixing flange is fixedly connected to the mounting bracket by the connecting bolts.

[0006] Preferably, the outer surface of the outer casing is provided with anti-slip texture.

[0010] Preferably, the damping device is a hydraulic damper.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, through the synergistic action of multiple buffer springs, buffer pads, and damping devices, the energy generated by an impact can be effectively absorbed when an LED light is subjected to a collision. The elastic deformation of the multiple buffer springs converts the kinetic energy of the impact into elastic potential energy, the buffer pads further buffer and absorb the energy, and the damping devices slow down the movement speed of the inner shell and prolong the energy absorption time, thereby greatly reducing the impact of the collision on the LED light and protecting the internal structure and light-emitting elements of the LED light. The design of the connecting components allows this device to be easily installed on various street light poles or mounting brackets, making it widely applicable. By replacing the connecting bolts and fixing flanges of different specifications, it can also meet the needs of different installation environments, improving the versatility of the device.

[0013] In this invention, the outer shell is made of a high-strength, high-toughness alloy material, while the inner shell is made of a lightweight plastic material.

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] Reference Figures 1-4 As shown, this utility model provides a technical solution: an LED lighting anti-collision buffer device, including an outer shell 1, an inner shell 2, a buffer assembly, and a connecting assembly. The outer shell 1 is a hollow cylinder with openings at the top and bottom. The inner wall of the outer shell 1 is provided with a guide groove 3. The inner shell 2 is a hollow cylinder with an outer diameter smaller than the inner diameter of the outer shell 1. The outer wall of the inner shell 2 is provided with a guide block 4 that cooperates with the guide groove 3. The inner shell 2 is used to install the main body of the LED lighting lamp. The buffer assembly includes multiple buffer springs 5 ​​and buffer pads 6. One end of the multiple buffer springs 5 ​​is fixed to the inner wall of the outer shell 1, and the other end of the multiple buffer springs 5 ​​is connected to the outer wall of the inner shell 2. The multiple buffer springs 5 ​​are evenly distributed between the inner shell 2 and the outer shell 1. The buffer pads 6 are respectively provided at the top and bottom of the inner shell 2 and between the inner shell 2 and the outer shell 1. On the opposite sidewalls of the housing 1, the connecting assembly includes a fixing flange 7 and connecting bolts 8. The fixing flange 7 is located at the bottom of the outer housing 1 and has a connecting hole 9. The fixing flange 7 is fixedly connected to the mounting bracket by the connecting bolts 8. Through the nested structure of the outer housing 1 and the inner housing 2, together with the buffer assembly and the connecting assembly, a multi-layer anti-collision buffer system is formed. Multiple buffer springs 5 ​​are evenly distributed between the inner housing 2 and the outer housing 1. Through elastic deformation, the collision kinetic energy is converted into elastic potential energy, reducing the transmission of impact force. The buffer pads 6 on the top, bottom and sidewalls of the inner housing 2 further absorb residual energy, preventing the inner housing 2 from directly colliding with the outer housing 1 and protecting the internal LED lighting body. The fixing flange 7 and connecting bolts 8 in the connecting assembly can realize the stable connection between the device and the mounting bracket, ensuring the reliability of the anti-collision structure.

[0022] Reference Figure 1 As shown in this embodiment: the outer surface of the outer shell 1 is provided with anti-slip texture. By setting the anti-slip texture, the friction between the colliding object and the surface of the outer shell 1 can be increased, the sliding displacement of the device during the collision can be reduced, and the buffer time can be extended. By extending the collision duration, the buffer spring 5 and the buffer pad 6 can absorb energy more fully, thereby improving the overall anti-collision effect.

[0023] Reference Figure 3As shown in this embodiment: multiple buffer springs 5 ​​are high-strength helical springs. By utilizing the higher fatigue resistance and elastic recovery capability of high-strength helical springs, they can maintain stable buffering performance after multiple collisions, avoiding the decrease in anti-collision capability due to spring fatigue failure. At the same time, their structural characteristics can evenly distribute the collision force, improving the reliability of the buffer assembly.

[0024] Reference Figure 3 As shown in this embodiment: the number of guide grooves 3 and guide blocks 4 is not less than three, and they are evenly distributed along the circumference of the outer shell 1 and the inner shell 2. By having no less than three guide grooves 3 and guide blocks 4 evenly distributed along the circumference, a stable guiding structure can be formed to ensure that the inner shell 2 slides smoothly along the axial direction within the outer shell 1, avoiding deviation or jamming during collision. This design can ensure that the buffer spring 5 is subjected to uniform force, improving the stability of the device during the collision process. The outer shell 1 is made of high-strength and high-toughness alloy material, and the inner shell 2 is made of lightweight plastic material.

[0025] Reference Figure 3 As shown in this embodiment, a damping device 10 is also provided between the outer shell 1 and the inner shell 2. One end of the damping device 10 is connected to the inner wall of the outer shell 1, and the other end of the damping device 10 is connected to the outer wall of the inner shell 2. The damping device 10 can provide damping force during the collision, slow down the movement speed of the inner shell 2, prolong the energy absorption time, and prevent secondary impact damage to the LED lighting lamp by suppressing the rapid rebound of the inner shell 2, making the buffering process smoother and further improving the anti-collision effect.

[0026] Reference Figure 3 As shown in this embodiment, the damping device 10 is a hydraulic damper. By utilizing the stable damping force output characteristics of the hydraulic damper, the buffer strength can be automatically adjusted according to the collision force to adapt to different impact scenarios. Its liquid damping medium can effectively dissipate collision energy. Compared with mechanical damping structures, it is more durable, has lower maintenance costs, and ensures long-term reliable buffering performance.

[0027] Working Principle: The user fixes the device to a street light pole or designated mounting bracket using the connecting components. When the LED light is impacted, the outer shell 1 first bears the impact force. Then, the inner shell 2 slides smoothly inside the outer shell 1 under the guidance of the guide groove 3 and guide block 4. At the same time, multiple buffer springs 5 ​​begin to elastically deform, converting the kinetic energy generated by the impact into elastic potential energy, effectively reducing the transmission of impact force to the inner shell 2. The buffer pad 6 is tightly attached to the contact area between the inner shell 2 and the outer shell 1, further absorbing residual energy and preventing damage caused by direct hard collision. The damping device 10 provides stable damping force during this process, slowing down the movement speed of the inner shell 2, allowing more time for the energy to be absorbed by the buffer components, avoiding secondary impacts that may be caused by the rapid rebound of the inner shell 2. This comprehensively protects the internal structure and light-emitting elements of the LED light, ensuring that it can still work normally after being impacted and extending its service life.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
