And the reserves of non-renewable energy resources are constantly reduced, electric automobile gradually starts to lead the trend of automobile industry.With electric automobile
Widely use, its endurance is poor, and speed-raising is slow etc., and performance issue is also increasingly protruded.As long as research finds to mitigate body of a motor car
Weight, just can effectively alleviate above mentioned problem, therefore electric automobile starts largely to use all-aluminium body.But, due to aluminum processing
Low precision, the feature being easily deformed so that doorframe sealing problem turns into a new problem again.Electric automobile is used as a kind of main flow
New traffic tool, its requirement in terms of noise is also more stricter than orthodox car, due to not having orthodox car engine
Ambient noise so that Feng Zaohe makes an uproar on road the main source as electric automobile noise, and it is topmost to influence Feng Zaohe roads to make an uproar
Factor is exactly automobile sealed performance, therefore the sealing of electric automobile doorframe becomes particularly important.
In order to strengthen the sealing effectiveness of automobile door frame, traditional automobile door frame sealing means are to surround whole automobile door frame side
Edge installs one of sealing strip, passes through the enough decrements pair formed between the multiple sealing lips and doorframe metal plate face inside sealing strip
Car door is sealed.Because automobile door frame is mostly combined by multiple layer metal metal plate, therefore the automobile door frame thickness distribution of one week
Be it is uneven, and upper vehicle body and under body junction also inevitable that gap, sealing difficulty further increases.Pin
For traditional alloy automobile vehicle body, although the automobile door frame thickness skewness of one week and there is gap, vehicle peace
Fill after use, the thickness change of automobile door frame is simultaneously little, and sealing strip can keep a good sealing property after being installed in place,
But the thickness drop of aluminum material is big, the sealing strip of variable cross-section thickness can not be produced based on existing process, so as to cause doorframe close
Sealing property is poor, and sealing strip is very unstable in use, easily produces dislocation, and sealing property is extremely low.
Correspondingly, this area needs a kind of new sealing device for vehicle body doorframe to solve the above problems.

Thickness, so as to influence the sealing effectiveness of sealing strip.Similarly, as described above, the sealing device of the present utility model for vehicle body doorframe
By setting boss in the part without reinforcer 8 so that the various pieces thickness of vehicle body doorframe is roughly the same, so that sealing
Better seal effect can be reached between bar and vehicle body doorframe, its specific fit system will combine Fig. 7 and Fig. 8 in detail below
Description.
As shown in fig. 6, the figure is the section signal of the sealing strip of the sealing device of the present utility model for vehicle body doorframe
Figure.This is sentenced before vehicle body exemplified by door weather strip 2, but the use of sealing strip 2 is not limited to vehicle body front door.Door weather strip 2 before vehicle body
Comprising two inner seal lips 9 and multiple rack-shaped outboard seal lips 10, after sealing strip is installed in place, sealing lip passes through extruding zero
Part mating surface reaches certain deflection, makes it have enough extruding forces, so as to realize sealing effectiveness.Furthermore, it is necessary to illustrate
, the concrete shape and characteristic size of sealing strip are not limited；The shape and quantity of sealing lip are not limited.
As shown in fig. 7, before the figure is the vehicle body being used in combination with the sealing device of the present utility model for vehicle body doorframe
Section two-dimensional representation after sealing strip is installed on the inside of door frame lower edge at boss.Part shown in figure includes body bottom
Longeron 4, the side-wall outer-plate 1 installed in the outside of body bottom longeron 4, door weather strip 2 before vehicle body, process in body bottom longeron 4
Reinforcer 8 at the boss 6 of inner side and preceding door frame B posts.The internal structure of door weather strip 2 includes inner seal lip 9 before vehicle body
With outboard seal lip 10.The interception of this figure is before vehicle body at the cooperation of door weather strip 2 and boss 6, and door weather strip 2 is installed to before vehicle body
Behind position, the inner seal lip 9 of door weather strip 2 is squeezed in the outer surface of boss 6 and forms certain deformation quantity before vehicle body, vehicle body front door
The outboard seal lip 10 of sealing strip 2 is then squeezed in the mating surface of side-wall outer-plate 1 and forms certain deformation quantity, now, before vehicle body
The deformation tension force of door weather strip 2 itself makes it produce enough extruding forces, and sealing strip 2 is secured firmly into door frame before vehicle body
On, the presence of boss 6 in addition make it that the various pieces thickness of vehicle body doorframe is roughly the same, so that the installation of sealing strip is more steady
Gu, sealing effectiveness is greatly increased.
As shown in figure 8, before the figure is the vehicle body being used in combination with the sealing device of the present utility model for vehicle body doorframe
Section two-dimensional representation after sealing strip is installed on the inside of door frame lower edge at rivet.Part shown in figure is vertical including body bottom
Beam 4, the side-wall outer-plate 1 installed in the outside of body bottom longeron 4, door weather strip 2 before vehicle body, the reinforcer 8 at preceding door frame B posts
With the rivet 7 for body bottom longeron 4 and reinforcer 8 and/or side-wall outer-plate 1, the internal structure bag of door weather strip 2 before vehicle body
Include inner seal lip 9 and outboard seal lip 10.This figure is intercepted before vehicle body at the cooperation of door weather strip 2 and rivet 7, vehicle body front door
After sealing strip 2 is installed in place, two inner seal lips 9 of door weather strip 2 are squeezed in the riveting for union piece respectively before vehicle body
The mating surface up and down of nail 7 simultaneously produces the outboard seal lip 10 of door weather strip 2 before certain deflection, vehicle body and is then squeezed in side-wall outer-plate
In 1 mating surface and producing the deformation tension force of door weather strip 2 before certain deflection, vehicle body itself makes it produce enough extruding force
Before sealing strip 2 is firmly squeezed on door frame, the presence of boss 6 in addition causes the various pieces thickness substantially phase of vehicle body doorframe
Together, the sealing effectiveness of sealing strip 2 has obtained further strengthening.Furthermore, it is necessary to explanation, body bottom longeron 4 is with adding
The connected mode of strong part 8 and/or side-wall outer-plate 1 is not limited to rivet interlacement, therefore, not as the limit to sealing strip use occasion
System.
So far, combined preferred embodiment shown in the drawings describes the technical solution of the utility model, still, this
Art personnel are it is easily understood that protection domain of the present utility model is expressly not limited to these embodiments.
On the premise of sealing principle of the present utility model, those skilled in the art can make equivalent to correlation technique feature
Change is replaced, and the technical scheme after these are changed or replaced it is fallen within protection domain of the present utility model.
