Description
Technical Field
[0001] The utility model belongs to the technical field of automobile manufacturing, and particularly relates to a front windshield sealing strip. Background Art
[0002] At present, rubber sealants are mostly used for the sealing of commercial vehicle body glass. As Figure 3 shown, it is the structure of the existing front windshield sealing strip of an automobile. After the existing sealing strip is assembled, the structure is as Figure 4 shown. Among them, the sheet metal stop groove and the windshield glass groove are in a parallel relationship. During assembly, the glass groove of the sealing strip is first clamped onto the front windshield glass to form a component, and then it is clamped onto the front windshield sheet metal of the automobile through the sheet metal stop groove. Due to the large area of the front windshield and the heavy weight of the front windshield glass, the operation is relatively difficult. At the same time, the requirements for the dimensional consistency of the glass and the sheet metal parts themselves are relatively high, which increases the manufacturing process difficulty. The relative position is relatively difficult to control. When the gap is small, it cannot be clamped, and when the gap is large, it is easy to loosen, affecting the clamping force. It is easy to come out during sudden braking and other situations. And because the clamping structure does not apply glue, there is a risk of water leakage inside the vehicle in rainy weather and other conditions. Summary of the Invention
[0003] The utility model aims to solve the problems existing in the existing method of using a sealing strip to clamp and seal the front windshield glass and the sheet metal part of an automobile. During assembly, due to the large area of the front windshield and the heavy weight of the front windshield glass, the operation is relatively difficult. At the same time, the requirements for the dimensional consistency of the glass and the sheet metal parts themselves are relatively high, which increases the manufacturing process difficulty. The relative position is relatively difficult to control. When the gap is small, it cannot be clamped, and when the gap is large, it is easy to loosen, affecting the clamping force. It is easy to come out during sudden braking and other situations. And because the clamping structure does not apply glue, there is a risk of water leakage inside the vehicle in rainy weather and other conditions. A front windshield sealing strip is provided. The sealing connection between the sheet metal part and the front windshield glass is realized through a glass adhesive. The outer edge of the front windshield glass is clamped and fixed through a glass groove. The first groove is enlarged by inserting the compression secondary lip of the sheet metal part into the first groove and deforming it. Furthermore, the end of the sealing cover of the strip presses the first connecting strip to press the front windshield glass, increasing the waterproof and dustproof effect.
[0004] In order to achieve the above object, the technical solution of the utility model is as follows:

[0011] 1. By changing the assembly of the front windshield sheet metal part and the front windshield from a clamping assembly process to an adhesive process, the connection between the two is realized through a glass adhesive and the sealing effect is ensured, avoiding the problems of difficult assembly and poor processing and manufacturing feasibility of the traditional structure. At the same time, the adhesive process can effectively avoid the problem of poor sealing due to small clamping force caused by the aging of the sealing strip.
[0012] 2. When the present utility model is installed, the outer panel of the A-pillar of the vehicle front panel compresses the secondary lip, and the end of one end is pushed into the first card slot, further expanding and deforming the first card slot, so that the end of the rubber strip sealing cover away from the first card slot is pressed towards the front windshield, and then the first connecting strip presses the front windshield surface, effectively increasing the dust and water prevention effect. A depression is formed between the L-shaped secondary lip corner and the outer panel of the A-pillar of the vehicle front panel, which is beneficial for drainage as a drainage ditch.
[0013] 3. By providing the decorative member of the A-pillar of the vehicle front panel, the overall appearance still maintains the effect of the traditional snap-fit structure, avoiding the defects that the caulking glue has uneven widths and heights of the glue seams due to the matching deviation of the surrounding environment, which affects the appearance.
