Abstract: This article studies the waterproof principle of the general and corner parts of glass run. Aiming at the problem that the unreasonable setting of the positioning block shape of glass run will affect the waterproofing of foam found in practice, the principle and the shape setting of the positioning block are studied. The solution is given, which provides an effective solution for the subsequent glass run positioning block design.
