Description

A kind of automobile door sealing bar

Technical field

The utility model relates to the arrangements for automotive doors annex, is specifically related to a kind of automobile door sealing bar.

Background technology

The sealing of door device is to lean on the compressive deformation of sealing band to come the slit between noggin piece; Make that vehicle body is indoor to be hedged off from the outer world; Can not only prevent that wind, rain and dust intrusion are indoor; Improve sound insulation and heat-proof quality, to keep environment inside car, impulsive force and vehicle body vibration in the process of moving in the time of can also relaxing movement parts such as car door simultaneously and close.And existing door sealing member is single seal form, promptly between car door and gusset, realizes the individual layer sealing function through the sealing strip for door frame of whole circle.No matter this hermetically-sealed construction still from the vibration damping and sound of shutter door in view of, all can not reach a kind of desirable effect from sealing effectiveness.

Summary of the invention

The purpose of the utility model is the deficiency that exists to prior art, and a kind of automobile door sealing bar is provided, and it can improve the sealing property of arrangements for automotive doors, prevents in wind, rain and the dust intrusion car protection environment inside car; Impulsive force and vehicle body vibration in the process of moving in the time of simultaneously can also relaxing closing of the door make it to have good sound insulation, heat insulation and vibration-damping function.

The described a kind of automobile door sealing bar of the utility model; Comprise back seal bar, lower seal bar; It is characterized in that: an end of said lower seal bar connects the angle through a left side and is connected with an end of back seal bar; The other end of lower seal bar connects the angle through the right side and is connected with the other end of back seal bar, constitutes door weather strip; Door weather strip embeds in the draw-in groove of vehicle door edge, and is fastened on the car door through a plurality of buckles.

Described a kind of automobile door sealing bar, the comprising and the male member of car door clamping and the foaming part that contacts with gusset of its said back seal bar; Said male member is closely knit elastomeric material, and said foaming partly is the elastomeric material of foaming, and two parts are shaped to one through the high temperature extruding.

Described a kind of automobile door sealing bar; The mounting portion that comprises buckle of its said lower seal bar and the blister part that contacts with gusset; The mounting portion of said buckle is closely knit elastomeric material, and said bubble is divided into the elastomeric material of foaming, and two parts are shaped to one through the high temperature extruding.

Described a kind of automobile door sealing bar, the material of its said back seal bar and lower seal bar is ethylene propylene diene rubber EPDM.

Said back seal bar and lower seal bar are under temperature is 120 ℃ situation, are extruded material from the mouth mould of head by the screw rod of tube inside spin, in high temperature vulcanized process, connect the angle with the right side connects corner connection through a left side afterwards, the formation door weather strip.This sealing band adopts elastomeric material to process, and sealing property is excellent, sound insulation, good damping result.

The embedded section structure of back seal strip adoption in the draw-in groove on the male member embedding car door on top, thereby is realized fixing; Contact with gusset through the blister position, play the leak free effect.Lower seal strip adoption plug-in section structure, elder generation is by the hole clipping of the termination clamping lower seal bar of buckle, and the taper position through buckle is fixed on the lower seal bar on the sheet metal component again, thereby sealing band is fixed; Contact with gusset through the blister position, play the leak free effect.Two different sections are through smart cut-grafting corner connection, thereby reach the leak free effect.

In order to strengthen the sealing function of door device, be double containment with the design of Sealing Structure of door device, the sealing system of both having formed by door case sealing band and door weather strip.The present invention is exactly on the basis of original door case sealing band, increases a door weather strip.

Owing to need good sealing property; And the gap between car door and the gusset is because production tolerance's cause can not keep two gaps between the part in full accord; So sealing band need be made with elastic body, like this during a kind of material, nearly all sealing band all selects for use elastomeric material to make in screening; Because rubber has the elasticity of good elasticity, particularly bipeltate and has especially and can not be substituted.Optimal design and material chosen through to gasket structure stopped to leak, poor air-tightness, improves the sound quality of opening/closing door of vehicle.

The beneficial effect of the utility model: through optimal design and material chosen, improved the sealing property of car door, stopped to leak, improved air-tightness, thereby improved the sound quality of opening/closing door of vehicle to gasket structure; Impulsive force and vehicle body vibration in the process of moving in the time of simultaneously can also relaxing closing of the door.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and a kind of automobile door sealing bar shown in Figure 5, comprise back seal bar 2, lower seal bar 3; One end of said lower seal bar 3 connects angle 4 through a left side and is connected with an end of back seal bar 2, and the other end of lower seal bar 3 connects angle 5 through the right side and is connected with the other end of back seal bar 2, constitutes door weather strip 1; Door weather strip embeds in the draw-in groove of vehicle door edge, and is fastened on the car door through a plurality of buckles 6.

Further, said back seal bar 2 comprises and the male member 9 of car door clamping and the foaming part 10 that contacts with gusset; Said male member is closely knit elastomeric material, and said foaming partly is the elastomeric material of foaming, and two parts are shaped to one through the high temperature extruding.The material of (referring to Fig. 2 and Fig. 7) said back seal bar 2 and lower seal bar 3 is ethylene propylene diene rubber.

Further; The mounting portion that comprises buckle 6 11 of said lower seal bar 3 and the blister part 12 that contacts with gusset; The mounting portion of said buckle is closely knit elastomeric material, and said bubble is divided into the elastomeric material of foaming, and two parts are shaped to one through the high temperature extruding.(referring to Fig. 3 and Fig. 8)
