Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a protective packaging device for vehicle headlights with an airbag-type anti-collision mechanism. Background Technology

[0002] In the field of automotive parts transportation, the packaging and protection of automotive headlights is of paramount importance. As a key component for vehicle illumination and warning, automotive headlights are mostly made of PC resin, which has advantages such as high toughness, high hardness, high strength, good light transmission, and UV resistance. However, it is extremely susceptible to damage during transportation due to collisions and shaking. Once the surface of the headlight cover is damaged or scratched, it will seriously affect the brightness and distribution of the light.

[0003] The patent CN201821431546, entitled "Turtle-style Buffer Structure and Special Packaging Box for Car Headlight Transportation," includes a central base, an upper wrapping section, and a support section. It uses three layers of corrugated cardboard to absorb impact and vibration energy, with a hollow triangular prism at the top reducing impact energy from above. The support section fits snugly with the outer box to prevent the buffer from shifting. However, this solution has significant drawbacks. Due to the rigidity of the three-layer corrugated cardboard, its energy absorption capacity is limited, making it difficult to effectively protect the internal components of the headlight during a collision during transport, resulting in poor overall protection. Another example is the use of blister-formed or injection-molded plastic shells covered with wooden crates and iron frames. While this provides some protection, it is heavy and costly, failing to meet the high-efficiency, low-cost protection requirements for long-distance or export transportation. Some solutions use non-environmentally friendly materials such as foam and bubble wrap as cushioning fillers, which are not only environmentally unfriendly but also result in large packaging volumes when used in bulk, making it difficult to achieve ideal protection.

[0004] Existing automotive headlight packaging and protection devices have shortcomings in terms of protective performance, cost control, environmental friendliness, and space utilization. Therefore, there is an urgent need for an innovative automotive headlight packaging and protection device to overcome these problems and achieve more efficient, reliable, economical, and environmentally friendly packaging and protection for automotive headlights.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a protective device for vehicle headlight collision avoidance airbag packaging, comprising an end cap and a housing, wherein a fixing component is disposed inside the housing, the fixing component comprising:

[0009] A mounting bracket is fixedly installed inside the outer casing in a grid pattern. The mounting bracket has non-penetrating holes for insertion into a mounting post.

[0010] Mounting holes are provided on the mounting bracket. The mounting holes are used to mount the vehicle light assembly. The mounting holes allow the vehicle light assembly to be suspended inside the housing, and the vehicle light assembly does not contact the housing.

[0011] At least one second airbag is fixedly disposed inside the mounting frame;

[0012] An airbag triggering device is provided inside the end cap. The airbag triggering device is used to inflate the second airbag when the device is tilted. The second airbag bulges out from inside the fixing frame into the gap between the headlight assembly and the housing.

[0013] Preferably, the airbag triggering device includes:

[0014] The first airbag is ring-shaped and its outer surface is fixedly connected to the inner wall of the end cap.

[0015] A pressure block is disposed inside the first airbag, and the pressure block is used to compress the first airbag when the device tilts.

[0016] Preferably, the end cap is provided with a groove located between the end cap and the first airbag. The groove is an arc-shaped inner groove body, which is used to guide the pressure block to slide away from the first airbag when the device returns to stability.

[0017] Preferably, the end cap is further provided with a limiting groove located on the groove. The limiting groove is an arc-shaped inner groove body. The limiting groove is used to limit the position of the pressure block when the device does not tilt violently.

[0018] Preferably, the end of the fixing frame is provided with a connecting hole, one side of the end cap is provided with a connecting tube for inserting into the connecting hole, and the other side of the end cap is provided with a venting tube communicating with the first airbag. The venting tube is located between the end cap and the groove. The venting tube is used to circulate the gas in the first airbag to the connecting tube, and the connecting tube is used to circulate the gas into the fixing frame through the connecting hole.

[0019] Preferably, there are at least two mounting brackets, and the two ends of the vehicle light assembly are respectively inserted into the mounting holes on the mounting brackets.

[0020] Preferably, the mounting bracket is provided with at least two buffer pads, which are fixedly connected to the mounting bracket and are located between the headlight assembly and the housing.

[0021] Preferably, an elastic buffer layer is provided on the outer wall of the fixing frame to provide initial buffering when the second airbag is not inflated.

[0022] Preferably, the connecting pipe is equipped with a one-way valve to prevent gas from flowing back from the fixing frame into the first airbag.

[0023] Preferably, a sealing ring is provided between the end cap and the outer shell, and the sealing ring surrounds the connection between the end cap and the outer shell to prevent the vehicle lamp assembly from being corroded by external dust and moisture during storage and transportation.

[0024] (III) Beneficial Effects

[0025] Compared with the prior art, this utility model provides a protective device for vehicle headlight collision avoidance airbag packaging, which has the following beneficial effects:

[0026] 1. This airbag-type protective packaging device for vehicle headlights uses a fixed component to suspend the headlight assembly within a fixed frame inside the outer shell, preventing direct contact between the headlight assembly and the outer shell. Combined with a second airbag inside the fixed frame, the elastic buffer layer on the outer wall of the fixed frame and the buffer pads in the mounting holes provide initial cushioning when the headlight assembly is not tilted, reducing the intensity of external forces acting directly on the headlight assembly. This achieves multi-layered, phased cushioning protection. By suspending the headlight assembly inside the outer shell, hard contact between the headlight assembly and the outer shell is further avoided, reducing the risk of scratches and compression caused by collisions.

[0027] 2. This airbag-type packaging protection device for vehicle headlights uses an airbag triggering device. When tipping occurs, the triggering device's pressure block compresses the first airbag, and gas flows through the vent pipe and connecting pipe into the second airbag. This causes the second airbag to bulge from inside the mounting bracket into the gap between the headlight assembly and the housing, filling the gap caused by shaking between the headlight assembly, the mounting bracket, and the housing. This forms an all-around airbag buffer structure, reducing the risk of damage such as loosening of internal parts and wear and tear caused by shaking, and effectively reducing the probability of headlight damage caused by collisions during transportation.

[0028] 3. This airbag-type packaging protection device for vehicle headlights, by setting grooves and limiting grooves on the end caps, can assist the pressure block in compressing the first airbag to complete the inflation action when the device is tilted. When the device returns to stability, it can guide the pressure block to reset. The limiting groove can also restrict the position of the first airbag when the device is not severely tilted, avoiding false triggering caused by normal handling or slight shaking. This saves unnecessary gas and airbag losses, and also reduces the trouble of unnecessary disassembly and inspection of the vehicle headlight components due to false triggering. It has the effect of reducing the sliding resistance of the pressure block and avoiding false triggering of the airbag, thereby improving the response sensitivity of the airbag triggering device and enhancing the stability of the packaging protection.

[0042] Example 1:

[0043] This embodiment provides a collision avoidance airbag-type packaging protection device for vehicle lights, which has the following technical features.

[0044] Please see Figure 1-8 An airbag-type protective device for vehicle headlight collision avoidance includes an end cap 1 and a housing 2. A fixing component 4 is disposed inside the housing 2. The fixing component 4 includes:

[0045] The fixing bracket 41 is fixedly installed inside the outer casing 2 in a grid pattern;

[0046] Mounting hole 45 is provided on the mounting bracket 41. Mounting hole 45 is used to install vehicle light assembly 5. Mounting hole 45 suspends vehicle light assembly 5 inside housing 2, and vehicle light assembly 5 does not contact housing 2.

[0047] Several second airbags 42 are fixedly installed inside the fixing frame 41;

[0048] An airbag triggering device 3 is provided inside the end cap 1. The airbag triggering device 3 is used to inflate the second airbag 42 when the device is tilted. The second airbag 42 bulges out from inside the mounting bracket 41 into the gap between the headlight assembly 5 and the housing 2.

[0049] It should be noted that the bottom of the outer shell 2 is welded with a mounting post, the fixing component 4 is inserted into the mounting post, and the fixing bracket 41 is provided with a non-penetrating hole for insertion into the mounting post.

[0050] The second airbag 42 is distributed in the gap between the headlight assembly 5, the mounting bracket 41 and the outer shell 2. The second airbag 42 is fixed on the mounting bracket 41 by means of bonding, welding or other methods. When the second airbag 42 is not inflated, it remains flat and is hidden inside the mounting bracket 41.

[0051] In an optional embodiment, the airbag triggering device 3 includes:

[0052] The first airbag 31 is ring-shaped and its outer surface is fixedly connected to the inner wall of the end cap 1.

[0053] A pressure block 32 is disposed inside the first airbag 31. The pressure block 32 is used to squeeze the first airbag 31 when the device is tilted.

[0054] In an optional embodiment, the end cap 1 is provided with a groove 11 located between the end cap 1 and the first airbag 31. The groove 11 is an arc-shaped inner groove body. The groove 11 is used to guide the pressure block 32 to slide away from the first airbag 31 when the device returns to stability.

[0055] In an optional embodiment, the end cap 1 is further provided with a limiting groove 12 located on the groove 11. The limiting groove 12 is an arc-shaped inner groove body. The limiting groove 12 is used to limit the position of the pressure block 32 when the device does not tilt violently.

[0056] It should be noted that both the groove 11 and the limiting groove 12 are arc-shaped inner grooves. The inner walls are polished to form a continuous, flat, and smooth curved surface without sharp edges. The limiting groove 12 is located on the arc surface of the groove 11. Compared with the groove 11, the limiting groove 12 has a larger arc-shaped concave angle, which allows the limiting groove 12 to effectively limit the sliding position of the pressure block 32 when the device does not tilt violently, ensuring that the pressure block 32 remains within the limiting groove 12 and preventing it from moving arbitrarily.

[0057] In an optional embodiment, the end of the fixing frame 41 is provided with a connecting hole 43, one side of the end cap 1 is provided with a connecting tube 14 for inserting into the connecting hole 43, and the other side of the end cap 1 is provided with a venting tube 13 communicating with the first airbag 31. The venting tube 13 is located between the end cap 1 and the groove 11. The venting tube 13 is used to circulate the gas in the first airbag 31 to the connecting tube 14, and the connecting tube 14 is used to circulate the gas into the fixing frame 41 through the connecting hole 43.

[0058] It should be noted that a fixed frame 41 is provided with two connecting holes 43. The connecting holes 43 are used to allow gas to pass into the fixed frame 41. The number and size of the connecting pipes 14 correspond to the connecting holes 43 and are used to fix the end cap 1 to the outer shell 2. This serves both to allow gas to pass through and to fix the end cap.

[0059] In an optional embodiment, there are two mounting brackets 41, with the two ends of the headlight assembly 5 inserted into the mounting holes 45 on the mounting brackets 41 respectively.

[0060] In an optional embodiment, two buffer pads 44 are provided on the mounting bracket 41. The buffer pads 44 are fixedly mounted on the mounting bracket 41 by means of bonding, welding or other methods. The buffer pads 44 are both located between the headlight assembly 5 and the housing 2.

[0061] It should be noted that the buffer pad 44 is not connected to the inside of the mounting bracket 41. The buffer pad 44 is set on the mounting bracket 41 and located between the housing 2 and the headlight assembly 5, and has the function of preventing the headlight assembly 5, which passes through the mounting hole 45, from being bumped and bent by the housing 2.

[0062] In an optional embodiment, an elastic buffer layer is provided on the outer wall of the fixing frame 41 to provide initial cushioning when the second airbag 42 is not inflated.

[0063] It should be noted that the elastic buffer layer is fixed to the outer wall of the mounting bracket 41 by means of bonding, welding or other methods. Its shape is designed to fit the corresponding position of the first airbag 31 on the mounting bracket 41. The elastic buffer layer has a hollow structure in the installation area of ​​the first airbag 31 to ensure that the first airbag 31 is not obstructed by the elastic buffer layer during inflation and triggering. At the same time, the elastic buffer layer is tightly attached to the mounting bracket 41 in other areas, providing initial buffer protection for the headlight assembly when the second airbag 42 is not inflated.

[0064] In an optional embodiment, a one-way valve is provided inside the connecting pipe 14 to prevent gas from flowing back from the fixture 41 into the first airbag 31.

[0065] In an optional embodiment, a sealing ring is provided between the end cap 1 and the outer shell 2. The sealing ring surrounds the connection between the end cap 1 and the outer shell 2 to prevent the vehicle lamp assembly 5 from being corroded by external dust and moisture during storage and transportation.

[0066] It should be noted that when the end cover 1 is opened, the connecting tube 14 on the end cover 1 is disengaged from the connecting hole 43, the gas in the fixing bracket 41 flows out from the connecting hole 43, and the second airbag 42 retracts into the fixing bracket 41 to reserve space for the movement of the vehicle light assembly 5 when it is removed from the housing 2 and the fixing bracket 41.

[0067] Working principle:

[0068] When the end cap 1 is closed, and the device is in a stable state, the pressure block 32 is located in the limiting groove 12 of the end cap 1. The first airbag 31 is not compressed and the internal gas is not released. The second airbag 42 is flat and hidden in the fixing frame 41. The elastic buffer layer on the outer wall of the fixing frame 41 provides initial buffering.

[0069] When the device tilts, the pressure block 32 slides out of the limiting groove 12 due to gravity and slides along the groove 11, compressing the first airbag 31. After the first airbag 31 is compressed, the internal gas enters the fixing frame 41 through the vent pipe 13, the connecting pipe 14, and the connecting hole 43, causing the second airbag 42, which is distributed in the gap between the headlight assembly 5, the fixing frame 41, and the outer shell 2, to inflate and fill the space between the headlight assembly 5 and the outer shell 2, forming further buffer protection and clamping and fixing the headlight assembly 5. The buffer pad 44 on the fixing frame 41 helps to prevent the headlight assembly 5 from being bent by the impact of the outer shell 2.

[0070] After the device returns to a stable state, the pressure block 32 slides away from the first airbag 31 under the guidance of the groove 11 and returns to the limiting groove 12.

[0071] When the end cap 1 is opened, the connecting tube 14 disengages from the connecting hole 43, the gas in the fixing bracket 41 flows out from the connecting hole 43, and the second airbag 42 retracts, making it easy to remove the headlight assembly 5.

[0072] In summary, by setting the fixing component 4, the headlight assembly 5 is suspended within the fixing frame 41 inside the housing 2, preventing direct contact between the headlight assembly 5 and the housing 2. Combined with the second airbag 42 inside the fixing frame 41, in the non-tilting state, the elastic buffer layer on the outer wall of the fixing frame 41 and the buffer pad 44 of the mounting hole 45 provide initial cushioning, reducing the intensity of external forces acting directly on the headlight assembly 5. This achieves multi-layered, phased buffering protection. By suspending the headlight assembly 5 inside the housing 2, hard contact between the headlight assembly 5 and the housing 2 is further avoided, reducing the risk of scratches and compression caused by collisions.

[0073] By setting up an airbag triggering device 3, when a tipping occurs, the pressure block 32 of the airbag triggering device 3 compresses the first airbag 31, and the gas is filled into the second airbag 42 through the vent pipe 13 and the connecting pipe 14, causing it to bulge from inside the fixing frame 41 toward the gap between the headlight assembly 5 and the outer shell 2, filling the gap between the headlight assembly 5, the fixing frame 41 and the outer shell 2 caused by shaking, forming an all-round airbag buffer structure, reducing the risk of damage such as loosening of internal parts and wear and tear caused by shaking, and effectively reducing the probability of damage to the headlight assembly 5 caused by collision during transportation.

[0074] By setting a groove 11 and a limiting groove 12 on the end cap 1, the pressure block 32 can assist in squeezing the first airbag 31 to complete the inflation action when the device is tilted. When the device returns to stability, the pressure block 32 can be guided to reset. The limiting groove 12 can also limit the position of the first airbag 31 when the device is not tilted violently, avoiding false triggering of the device under normal handling and slight shaking scenarios. This saves unnecessary gas and airbag losses, and also reduces the trouble of unnecessary disassembly and inspection of the headlight assembly 5 due to false triggering. It has the effect of reducing the sliding resistance of the pressure block 32 and avoiding false triggering of the airbag, thereby improving the response sensitivity of the airbag triggering device 3 and enhancing the stability of the packaging protection.
