Description
Technical Field
The invention belongs to the technical field of automobile parts, relates to an automobile door frame, and particularly relates to a lightweight automobile door frame section.
Background
The automobile door frame is generally mainly formed by rolling a plurality of folding parts and has a complex cross-sectional shape, then a reinforced middle column plate is arranged on the upper transverse direction of the door frame section, a first jogging part is rolled on one side of the door frame section for assembling the lifting glass sealing strip, a second jogging part is rolled on the other side of the door frame section for assembling the door weather strip, the door frame section of the structure is formed by rolling stainless steel materials, the automobile door frame section is heavy, the section rolling process step is complex, for example, the first jogging part and the second jogging part on the left side and the right side of the whole door frame can be seen, thus not only wasting the whole door frame material, but also the welding process is required after the rolling, the production procedure is complex, along with the development of the light weight technology, the whole automobile is required to be lighter, the quality is more reliable, and the whole door frame section is manufactured by adopting light alloy materials, so that the improvement on the existing automobile door frame section is required.
Disclosure of Invention
Aiming at the current state of the art, the invention provides a lightweight automobile door frame section with good overall strength, light weight and reduced production cost.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a lightweight car door frame section, its characterized in that, holistic section is by light alloy material extrusion molding, this section is including pocket portion and the pillar board cooperation portion of downside, the up end of pillar board cooperation portion extend straight right, up end is the outward appearance mating surface, pocket portion and pillar board cooperation portion between have connection transition portion, connection transition portion right side have door stop caulking groove portion, door stop caulking groove portion form by the raised head of the lower terminal surface of center pillar cooperation portion and the perk hook on connection transition portion right side, pocket portion and the left side of connection transition portion between have lower bevel arc mouth, the left side of lower bevel arc mouth upwards lifts up and forms lower anticreep portion, the left side of connection transition portion has smooth transition portion, smooth transition portion crooked extension right be connected with pillar board cooperation portion directly.
The biggest innovation of the invention is that the whole section can be molded by adopting a light alloy material such as aluminum alloy through an extrusion process, the biggest difference between the extrusion process and a rolling process is that the section per se has a certain thickness during extrusion, the strength is good, the material is light, the caulking groove which is originally needed to be matched with a glass sealing strip is directly omitted in order to make the section of the whole automobile door frame lighter, the smooth transition part is directly connected with the column plate matching part, the whole section structure can be seen to be only the structure of the lower bevel arc part, the left upper part of the whole section is directly omitted, the material is saved, and the production cost is reduced.
In the lightweight car door frame section, still install the roll bending center pillar board on this door frame section, roll bending center pillar board including the main part, the right-hand member of main part is buckled and is formed with pothook portion, the left side of main part have and push down flange portion and locking welt portion, locking welt portion paste on the left surface of connecting transition portion, push down flange portion, locking welt portion and lower oblique arc portion constitution supply glass sealing strip assembled lift caulking groove portion.
In the section of the lightweight automobile door frame, the lifting caulking groove is internally provided with the glass sealing strip, and the locking piece is used for locking the glass sealing strip, the locking welt part and the connecting transition part after penetrating through the lifting caulking groove.
Here again in order to install fixed whole glass sealing strip, through the structure to the center pillar board changes, can see here that the left side of roll bending center pillar board is having a flange portion that pushes down and a locking flange portion, the flange portion that pushes down here is used with lower bevel connection portion cooperation, so after glass sealing strip installs in, just can block glass sealing strip through flange portion and lower bevel connection portion down, prevent whole glass sealing strip to deviate from, in addition, in order to fix roll bending center pillar board, laminate through locking flange portion and connection transition portion, then pass through the locking piece and pass through from the lift caulking groove after with glass sealing strip, locking flange portion and connection transition portion lock, so just so make glass sealing strip inwards push down locking flange portion again, and push down flange portion pushes down glass sealing strip, even under the circumstances of saving the upper left portion of section like this, under the circumstances of saving material, also can realize glass sealing strip and center pillar board's installation, manufacturing cost has been reduced.
