Problems solved by technology
The use of this material can indeed ensure the airtight performance of the headlamp, but the hardness of this material is relatively high, including shA40-shA45, and its compression force is relatively large, so a large torque is required when screwing in and out of the back cover, so that Excessive torque for disassembling the rear cover
Moreover, the aging cycle of EPDM material is short, and the hardness will increase significantly after being placed for three days, and the disassembly torque will become larger, which will bring inconvenience to the disassembly and maintenance of automobile headlights.

The invention provides an automotive headlamp rear cover sealing structure which comprises a rear cover, a sealing ring and a lamp body. The rear cover is provided with a connecting part extending inthe left-right direction, the sealing ring is arranged on the connecting part in a sleeving manner, the left end of the connecting part is provided with a first sealing part extending in the inside-outside direction, the right end of the connecting part is detachably connected with the lamp body, and a second sealing part extending in the inside-outside direction is arranged on the lamp body; andthe first sealing part and the second sealing part abut against the left and right sides of the sealing ring tightly. According to the automotive headlamp rear cover sealing structure, the rear coveris detachably connected with the lamp body, and therefore mounting and demounting of the rear cover are facilitated; meanwhile, the first sealing part and the second sealing part abut against the leftand right sides of the sealing ring tightly, and therefore the sealing function on the lamp body is achieved; and in addition, the overall automotive headlamp rear cover sealing structure is simple and convenient to machine.
Description
technical field [0001] The invention relates to a sealing structure, in particular to a sealing structure for the rear cover of an automobile headlamp. Background technique [0002] With the rapid development of the automobile industry, the structure and function of automobile headlights have been fully developed. Headlights are not only required to fulfill their functional requirements, but also to meet the requirements of stronger functionality and better aesthetics. The headlights of many cars have become their unique and iconic parts. In the performance standards of automobile headlights, air tightness is one of the very important indicators. If the airtightness of the headlight is not good, it will cause water to enter the headlight, and there will be fog in the lamp, which will directly affect its function and appearance, and even cause serious car accidents and other consequences. Moreover, in the structure of the headlight, there are one or more back covers for ea...
