Above-mentioned technical matters of the present invention is mainly solved by following technical proposals: a kind of sealing band, comprise bar shaped elastic body, body establishes the sealing member of cavity in being, have can be fixed on vehicle body bottom surface, with outside withhold the relative end face in face, it is characterized in that: end face is provided with lip limit, this lip limit is strip-like resilient body, arranges along body length direction; One side on lip limit is fixed on end face, the free end opposing top oblique extension relative with fixed edge or cover on end face.This structure, weatherstrip body plays buffering, fixation, and lip limit is only main hermetically-sealed construction, is to be abutted on lip limit by car door, produces sealing effectiveness by squeezing action.Due to the free deployed configuration that a limit on lip limit is fixing, in the crumpling process of car door, play shock absorbing effect primarily of weatherstrip body, and lip limit remains good elasticity, make leak tightness remain at good state.
For ease of making, as preferably, lip limit and body are structure as a whole or Split type structure; During integrative-structure, lip limit is the shoestring extended from body matrix; During Split type structure, lip limit bonds or snaps onto on body.In addition, during Split type structure, adopt snapping to connect, lip limit can being changed easily, without the need to changing sealing band entirety, use cost and maintenance cost can be saved.
For improving anti-seismic performance, as preferably, the cavity of described body extends to body two ends.This structure, during car door crush seal bar, gas compression in the cavity of body, plays better damping, buffer action, and under larger vibrations, the power that still can provide support makes lip limit and car door keep reclining and seal.Although this measure expansion, reduce the elasticity of body, because main sealing element is lip limit, lip limit does not reduce elasticity because of this measure expansion, so sealing property can not decline.
In order to obtain good leak tightness, as preferably, the body surface relative with lip limit medial surface is outer arcuate curved surface.The structure of outer arcuate curved surface, makes lip limit and body also can keep good contact, makes also can obtain good sealing property between lip limit and body.
As a kind of additional project of selectable such scheme, the body surface relative with lip limit medial surface swells a projection, this projection along lip limit move towards arrange, and depart from connecting portion one segment distance of lip limit and body.This structure, during car door extruding, body is contacted with lip limit by protruding, and can obtain and contact effect preferably, make contact portion between the two be in same projection, each contact point is continuous print, and form complete continuous print contact surface, sealing effectiveness is better; Avoid each contact point to scatter discontinuously, make sealing surface concentrated not.
For the ease of fixing, as preferably, the bottom surface of body is provided with the latch that several can insert the corresponding fixed orifice of vehicle body.This structure, installs and changes all more for convenience.
As preferably, the main body of latch is column, on column outer peripheral face circumference be evenly equipped with some groups protruding, often organize projection and have some layers, each layer is axially arranged along column successively.This multi-layer bumps structure, has good reliability, avoids one deck structural failure just to cause entirety to come off, and when one deck lost efficacy, another layer under it still can play fixation.
As preferably, body and latch are the integral structure adopting a kind of material integral production.Can manufacturing cost be reduced, in addition, also can reduce the possibility that split type latch destroys the gas leakage of sealing band cavity.
Therefore, the present invention have rational in infrastructure, be easy to the features such as manufacture, especially there is the beneficial effect that anti-seismic performance is good, still can keep better sealing property in larger vibrations.
