Abstract
A kind of high strength special-shaped doorframe, including body, a kind of high strength special-shaped doorframe, including body, the doorframe that cross section is right-angled trapezium is bent into by body, the sealing part of doorframe is outward extended with registration arm, and the angle formed between registration arm and doorframe hypotenuse is obtuse angle；The structure of registration arm is：The tail end outward bending of body is extended with the first arm body, the head end outward bending of body is extended with the second arm body, and the first arm body and the second arm body are in overlapping shape.Not only good appearance, craft precision are guaranteed the utility model, also substantially increase production efficiency, improve product quality, can be widely applied to the automobile bodies doorframe of this class formation.
Description
Technical field
Auto parts and components field is the utility model is related to, especially a kind of high strength special-shaped doorframe.
Background technology
Doorframe is the side door plate of clamshell doors vehicle, the important component of Rear Door, primarily serves connection, fixed each door-plate
And the gap between guarantee each door of clamshell doors, prevent the effect that loaded article leaks in vehicle.
Split door frame is now：As shown in figure 1, a slotted-angle shelving 2, angle are welded on the rectangle doorframe 1 of current standard
Steelframe plays a part of to position doorframe, and the mode so combined brings a series of harm to subsequent operation, taken a lot of work, time-consuming, more
Welding rod, grinding wheel etc. are consumed, craft precision is poor, low production efficiency, the inaesthetic problem of product design.
The content of the invention
To overcome poor existing split door frame craft precision, low production efficiency, the inaesthetic technological deficiency of product design, this
Utility model proposes a kind of high strength special-shaped doorframe；Not only good appearance, craft precision are guaranteed, and also substantially increase life
Efficiency is produced, product quality is improved, can be widely used for the automobile bodies doorframe of this class formation.
Therefore, the technical solution of the utility model is：A kind of high strength special-shaped doorframe, including body, it is characterised in that：By
Body is bent into the doorframe that cross section is right-angled trapezium, and the sealing part of doorframe is outward extended with registration arm, and registration arm is oblique with doorframe
The angle formed between side is obtuse angle；The structure of registration arm is：The tail end outward bending of body is extended with the first arm body, body
Head end outward bending is extended with the second arm body, the first arm body and the second arm body in overlapping shape.
To the further restriction of above-mentioned technical proposal, the head and the tail both ends of the body are connected to by ratio-frequency welding welding manner
Together.Advantage：Ratio-frequency welding welding manner has the advantages of operating speed is fast, weld strength is high, welding quality is high.
To the further restriction of above-mentioned technical proposal, the body is steel pipe.Steel pipe have intensity it is high, it is in light weight, use
The advantages of long lifespan.
Beneficial effect：The utility model compared with prior art, has advantages below：1. doorframe is right-angled trapezium, it inclines
Hypotenuse solves doorframe and the gapless problem of column；2. the first arm body and the second arm body that bend extension instead of prior art
Slotted-angle shelving and both with doorframe one-shot forming, reduce welding procedure, while save material；3. the utility model is not only outer
Shape is attractive in appearance, and craft precision is guaranteed, and also substantially increases production efficiency, improves product quality, can be widely applied to this
The automobile bodies doorframe of class formation.
Brief description of the drawings
Fig. 1 is the structural representation in background technology.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is use state figure of the present utility model.
Embodiment
As shown in Fig. 2 a kind of high strength special-shaped doorframe, including body 3, cross section is bent into as right-angled trapezium by body
Doorframe, the sealing part of doorframe are outward extended with registration arm；The angle formed between registration arm and doorframe hypotenuse is obtuse angle；Registration arm
Structure be：The tail end outward bending of body is extended with the first arm body 4, the head end outward bending of body is extended with the second arm body 5,
In overlapping shape, the middle cavity that ensure that doorframe is right-angled trapezium for first arm body 4 and the second arm body 5；The elongated end of first arm body 4 is anti-
5 elongated ends after to bending with the second arm body are docking together, and connected mode is welded for ratio-frequency welding.
As shown in Fig. 2 the right-angled trapezium doorframe is one-time formed by roll-in or impact style；Doorframe can be according to vehicle
Needing can varying cross section size.
As shown in figure 3, enumerate carriage side door use state：After carriage side door closure, its registration arm rides over compartment frame 6
On, a corner of compartment frame so solves the problems, such as to be not easy to open the door between registration arm and doorframe hypotenuse.
Special-shaped doorframe refers to that doorframe is unconventional shape.
Claims (3)
1. a kind of high strength special-shaped doorframe, including body, it is characterised in that：The door that cross section is right-angled trapezium is bent into by body
Frame, the sealing part of doorframe are outward extended with registration arm, and the angle formed between registration arm and doorframe hypotenuse is obtuse angle；Registration arm
Structure is：The tail end outward bending of body is extended with the first arm body, the head end outward bending of body is extended with the second arm body, and first
Arm body and the second arm body are in overlapping shape.
A kind of 2. high strength special-shaped doorframe according to claim 1, it is characterised in that：The head and the tail both ends of the body pass through height
Frequency weldering welding manner links together.
A kind of 3. high strength special-shaped doorframe according to claim 1 or claim 2, it is characterised in that：The body is steel pipe.
