Abstract
The utility model discloses an integral closed big return bend of driver's back skeleton is buckled by same steel pipe to form to by last horizontal pipeline section, the lower rectangle frame that encloses of horizontal pipeline section, left riser section and right riser section, in another end of draw mode inserted steel pipe is adopted to an end of steel pipe, and be in the same place to adjacent ground solder bumps, the butt joint position is located the middle part of transverse tubule section down, the width of rectangle frame is increased to well upper portion by upper portion gradually, is remained unchanged to the lower part by well upper portion. When integral closed greater curvature sealing of tube constituted the back skeleton, the back skeleton was at durable fatigue test in -process, and partial stress energy seals on big return bend transmits the angle modulation ware rapidly through integral, only very little some be used in on the big sideboard of the left and right side of back to very easily through the durable fatigue test of back skeleton.
Description
Technical field
The utility model relates to automotive seating art field, is specifically related to a kind of part structure on officer's seat back-rest framework.
Background technology
As shown in Figure 4, officer's backrest frames forms primarily of the half of formula bend pipe 6 of side plate 4 big on the right side of big on the left of backrest side plate 3, backrest, backrest recliner core members 5 and backrest frames. On the left of backrest, the lower end of big side plate 3 is provided with backrest recliner core members 5. When backrest frames does fatigue durability test, on the left of backrest on the right side of big side plate 3, backrest the half of formula bend pipe 6 of big side plate 4 and backrest frames to weld place's stress ratio more concentrated, it is easy to fracture, thus cause test failure to pass through.
Practical novel content
The utility model aims to provide a kind of officer's backrest frames monoblock type and closes big syphon, solves officer's backrest frames welding stress and concentrates, produces fracture, cannot by the problem of test.
For this reason, the technical scheme that the utility model adopts is: a kind of officer's backrest frames monoblock type closes big syphon, it is bend by same steel pipe, and the rectangle frame surrounded by upper lateral tube section, bottom rail pipeline section, left standpipe section and right standpipe section, one termination of steel pipe adopts in another termination that draw mode inserts steel pipe, and ground connection is welded together, described docking location is positioned at the middle part of bottom rail pipeline section, the width of described rectangle frame is increased to middle top gradually by top, remains unchanged to bottom by middle top.
Preferred as such scheme, the anterior left and right of described upper lateral tube section is arranged at intervals with flattening portions, two local, rests the head on square tube for welding metal.
The beneficial effects of the utility model: backrest frames big syphon is designed to monoblock type and closes big syphon, and bend pipe two ends joint is interspersed in the other end in the way of a draw, then it is connected with welding process, and weld is positioned at the middle part of bottom rail pipeline section. When monoblock type closes big syphon welding formation backrest frames, backrest frames is in fatigue durability test process, part stress energy is closed big syphon by monoblock type and is delivered to rapidly in recliner, an only very little part acts on the big side plate of backrest left and right side, thus is very easy to by backrest frames fatigue durability test.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlargement figure of Fig. 1.
Fig. 3 is officer's backrest frames of the utility model composition.
Fig. 4 is the structural representation of tradition officer's backrest frames.
Embodiment
Below by embodiment and by reference to the accompanying drawings, the utility model is described in further detail:
Shown in composition graphs 1 Fig. 2, a kind of officer's backrest frames monoblock type closes big syphon, is bend by same steel pipe, and the rectangle frame surrounded by upper lateral tube section, bottom rail pipeline section, left standpipe section and right standpipe section. One termination of steel pipe adopts in another termination that draw mode inserts steel pipe, and ground connection is welded together. Bottom rail pipeline section is relative to upper lateral tube section, bottom rail pipeline section, left standpipe section, and the reactive force born is minimum, and therefore, docking location is positioned at the middle part of bottom rail pipeline section. The width of rectangle frame is increased to middle top gradually by top, remains unchanged to bottom by middle top, increases the intensity of whole rectangle frame.
Preferably, the anterior left and right of upper lateral tube section is arranged at intervals with flattening portion 1, two local, for welding metal headrest square tube.
Shown in composition graphs 3, flattening portion 1, local is for welding metal headrest square tube 2, and left standpipe section is welded with side plate 3 big on the left of backrest, and right standpipe section is welded with side plate 4 big on the right side of backrest.
Claims (2)
1. officer's backrest frames monoblock type closes big syphon, it is characterized in that: be bend by same steel pipe, and the rectangle frame surrounded by upper lateral tube section, bottom rail pipeline section, left standpipe section and right standpipe section, one termination of steel pipe adopts in another termination that draw mode inserts steel pipe, and ground connection is welded together, described docking location is positioned at the middle part of bottom rail pipeline section, and the width of described rectangle frame is increased to middle top gradually by top, remains unchanged to bottom by middle top.
2. close big syphon according to officer's backrest frames monoblock type according to claim 1, it is characterised in that: the anterior left and right of described upper lateral tube section is arranged at intervals with two flattening portion, local (1), for welding metal headrest square tube.
