Description

Technical Field

[0001] The invention relates to a European-style guide groove anti-cracking structure and method, which is used for the connection between the top strip of the European-style rear door guide groove and the corner window. Background Art

[0002] At present, the European style guide groove top strip is made of PP+TPV material. The glass as a whole is joined to the top strip 1 with TPV corner material edging 3. The joint strength between the corner window 2 and the top strip 1 is maintained by the corner material. The TPV corner material itself has weak shear strength. A single force point is applied to the guide groove top strip. Due to the overall weight of the corner window, a shear torque is formed at the joint line 5, resulting in cracks at the joint line. The entire guide groove is scrapped, with a scrap rate of 70%. The qualified rate of the product before loading is low. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a European guide groove anti-cracking structure and method, which can effectively prevent the corner material from cracking due to shear force at the corner joint line.

[0004] The object of the present invention is achieved in that:

[0005] A European guide groove anti-cracking structure comprises a top strip and a glass corner window, wherein the glass corner window is combined with the top strip through edging, wherein the edging adopts TPV corner material, wherein a first clamping groove is arranged on the top strip, and a second clamping groove is arranged on the edging, wherein the first clamping groove and the second clamping groove are clamped with a support block at the same time, and the support block comprises a clamping part and an exposed part, wherein the clamping part matches with the first clamping groove and the second clamping groove, wherein a groove is arranged inside the exposed part, and a limiting part is arranged on the top of the exposed part.

[0006] Preferably, the clamping portion is provided with reinforcing ribs.

[0007] Preferably, the exposed portion is provided with a certain slope, and the thickness of the exposed portion near the clamping portion is smaller than the thickness of the top of the exposed portion.

[0008] Preferably, the support block is made of a mixed material of PP and 30% glass fiber GF.

[0009] Preferably, the first card slot and the second card slot are both U-shaped slots.

[0010] A European guide groove anti-cracking method adopts the above structure, and the anti-cracking method comprises the following steps:

[0011] Step 1: Hold the exposed part, level the two ends of the exposed part, align one end of the clamping part with the first clamping slot on the top strip, and align the other end with the second clamping slot on the edge;

[0012] Step 2: Find a starting point for installing a support block on the glass corner window, and engage the two ends of the clamping portion with the first clamping slot and the second clamping slot respectively;

[0013] Step 3: When the limiting portion contacts the first card slot or the second card slot, the card connection is completed;

[0014] Step 4: Before loading, pull the support block out of the guide groove.

[0015] The beneficial effects of the present invention are:

[0016] The present invention can prevent the cracking of the bonding line, and the cracking rate of the entire guide groove is reduced from 70% to 5%, which greatly improves the qualified rate of the product; the support block can be recycled and reused many times, which reduces the cost.
