Abstract

The utility model discloses a kind of novel backrest pipe frame, it, which includes, is bent into close-shaped pipe frame body by one whole pipe fitting, wherein, the both ends joint location of the pipe fitting is in whole pipe frame body lower end, and the one end of pipe fitting strikes out flat curved pipe, the rounded pipe in the other end, the flat curved pipe are erected on the round tube, and have process gap on the outside of the round tube.Further, the flat curved pipe is connected with round tube welding；The pipe frame body upper end has two stamped grooves；Between the flat curved pipe and the round tube to set up direction consistent with the setting direction of the pipe frame body；The both ends joint location of the pipe fitting is in the pipe frame body lower part centre position.The utility model is novel in design, makes convenient and ensures that foreign matter can drop out naturally in pipe fitting, so as to avoid shaping backing tube frame from sending the sound or influence the situation generation of whole product service life.

Description

Novel backrest pipe frame

Technical field

A kind of novel backrest pipe frame is the utility model is related to, belongs to automobile seat technical field.

Background technology

In automobile seat design process, requirement of the chair framework for intensity is often very high, because vehicle When being hit because of accident etc., the occupant of seat can produce shock loading to seat.In order to ensure the personal safety of occupant, it is necessary to Using the chair framework of high intensity, designed in addition in view of the load-carrying of vehicle entirety, also to reduce the weight of chair framework itself as far as possible Amount.Specific such as backing tube frame ordinary circumstance is that pipe frame shape is manually bent using a whole straight tube, and end is entered Row butt welding, to ensure the performance and intensity requirement of whole backing tube frame.

But in actual job, cause whole backing tube frame in movement because backing tube inframe enters such as welding impurity etc. During send the sound, and the service life of backing tube frame is influenceed, on the other hand, the utility model changes to existing backing tube frame Enter design.

The content of the invention

For above-mentioned weak point of the prior art, the utility model aims to provide a kind of novel backrest pipe frame, and it sets Meter is novel, makes convenient and ensures that foreign matter can drop out naturally in pipe fitting, and the sound or shadow are sent so as to avoid being molded backing tube frame The situation for ringing whole product service life occurs.

To achieve these goals, the technical solution of the utility model：A kind of novel backrest pipe frame, it includes by one Whole pipe fitting is bent into close-shaped pipe frame body, wherein, the both ends joint location of the pipe fitting is in whole pipe frame sheet Body lower end, and the one end of pipe fitting strikes out flat curved pipe, the rounded pipe in the other end, the flat curved pipe is erected on the circle Guan Shang, and there is process gap on the outside of the round tube.

Further, the flat curved pipe is connected with round tube welding.

Further, the pipe frame body upper end has two stamped grooves.

Further, the setting side for setting up direction and the pipe frame body between the flat curved pipe and the round tube To consistent.

Further, the both ends joint location of the pipe fitting is in the pipe frame body lower part centre position.

The beneficial effects of the utility model：Modern design, by improving the ingenious connection at pipe fitting both ends, to ensure pipe fitting Interior foreign matter can be dropped out naturally, and the sound or the situation hair of the whole product service life of influence are sent so as to avoid being molded backing tube frame It is raw.

Brief description of the drawings

Fig. 1 is stereogram of the present utility model；

Fig. 2 is Fig. 1 front view；

Fig. 3 is along the sectional view of line A-A in Fig. 2.

Embodiment

The utility model is further described with reference to specific embodiment and accompanying drawing.

A kind of novel backrest pipe frame as described in Fig. 1-Fig. 3, its include be bent into by one whole pipe fitting it is close-shaped Pipe frame body 1, wherein, the both ends joint location of pipe fitting is in the whole lower end of pipe frame body 1, and the one end punching press of pipe fitting Into flat curved pipe 3, the rounded pipe in the other end, the flat curved pipe 3 is erected on round tube, and has technique on the outside of the round tube Gap 4.

The utility model is by improving the ingenious connection at pipe fitting both ends, to ensure that foreign matter can drop out naturally in pipe fitting, So as to avoid shaping backing tube frame from sending the sound or influence the situation generation of whole product service life.

Specifically, pipe fitting one end passes through punch forming so that it turns into flat curved pipe 3, and the other end is then directly using just Beginning state is round tube, then whole pipe fitting is bent so that pipe fitting both ends, flat curved pipe 3 are ridden upon on round tube, and It is connected by welding, such as spot welding.In order to ensure the stability of whole backing tube frame, by between flat curved pipe 3 and round tube It is consistent with the setting direction of pipe frame body 1 to set up direction, and the both ends joint location of pipe fitting is among the bottom of pipe frame body 1 Position.

Finally, there are two stamped grooves 2 in the upper end of pipe frame body 1, for being used during subsequently assembling.

The technical scheme provided above the utility model embodiment is described in detail, used herein specifically Individual example is set forth to the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to help Assistant solves the principle of the utility model embodiment；Meanwhile for those of ordinary skill in the art, implement according to the utility model Example, the there will be changes in embodiment and application, in summary, this specification content should not be construed as To limitation of the present utility model.
