Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example one
The wheel arch sealing structure for the light truck comprises a wheel arch 11, a side wall metal plate 12 and a sealing strip 13, wherein the sealing strip 12 is of an integrally formed d-shaped structure, and the sealing strip of the d-shaped structure comprises a linear sealing body 13, a bubble tube 15 formed on one side of the linear sealing body 13, and a shielding edge 16 and a lip edge 17 formed at the end part of the linear sealing body 13; the edge covering 16 is bent and extended to one side along the end part of the linear sealing body 13, the bottom surface of the edge covering is covered on the end surface of the wheel arch 11, the lip edge 17 is bent and extended to the other side along the end part of the linear sealing body 13, the position of the lip edge is the same as that of the bubble tube 15, and the bottom surface of the lip edge is covered on the side wall metal plate 12. The assembling and connecting relationship of the sealing strip 13 is as follows: the plane side of the linear seal body 13 of sealing strip 13 is fixed with the bonding of wheel arch 11 through double faced adhesive tape 14, the opposite side bubble pipe 15 and the cooperation of side wall panel beating 12 pressure contact of the linear seal body 13 of sealing strip 13, the bonding structure of wheel arch 11 and sealing strip 13 is sheltered from in the visible department of outward appearance to the bank of protection 16 that sealing strip 13 upper portion right side set up, the lip limit 17 that sealing strip 13 upper portion left side set up then shelters from the junction of sealing strip 13 and side wall panel beating 12, makes the recess of bubble pipe 15 and the extrusion of side wall panel beating 12 form shield, improves the outward appearance effect.
