Description

The metal plate shell of aero seat and the connection structure of skeleton

Technical field

The utility model relates to aero seat technical fields.

Background technique

Carbon fiber is high intensity, the new fiber materials of high modulus fibre of a kind of phosphorus content 95% or more.It is by piece The organic fibers such as shape graphite microcrystal are piled up along fiber axial direction, through micro crystal graphite obtained from carbonization and graphitization processing Material.Carbon fibre composite light weight, intensity are high, in the case where meeting structural member performance requirement, can subtract with metal phase ratio Weigh 70%~80%；Carbon fibre composite also has good fatigue durability and corrosion resistance, and noise is small, vibration declines Subtracting property is good, safety is good, is particularly suitable for production aero seat skeleton.

Aero seat has metal plate coverboard, is mounted on the cladding foam that support seat is used on skeleton.But carbon fiber Skeleton and metal material coverboard between can not using be welded to connect, can only be bolted, still, the intensity of carbon fiber pipe Greatly, hardness is high, and drilling easilys lead to skeleton and splits, and reduces the security performance of skeleton.

Utility model content

In order to solve the above-mentioned technical problem the utility model, redesigns the connection structure of metal plate shell and skeleton, no Drilling can be achieved with metal plate shell on carbon fiber pipe and frame bolt is connected.

In order to achieve the above objectives, the technical solution of the utility model is as follows:

The metal plate shell of aero seat and the connection structure of skeleton, including metal plate shell and skeleton, the metal plate shell cover It covers above the skeleton；The skeleton is square, is interconnected by four L shape pipe fittings by two parts head and the tail；The pipe Part is made of inner layer metal pipe and outer layer carbon fiber pipe, and the both ends of the metal tube are exposed to outside the carbon fiber pipe；It is described There is insertion hole, the metal tube is fixed by bolts into after inserting in the hole in two connectors of two parts；The metal plate shell Body corresponds to the arc bound edge for being provided with and being coated in two parts at two parts, and the arc bound edge is bolted on institute On the middle interconnecting piece for stating two parts.

Further, the cross section of the inner layer metal pipe is regular hexagon, two parts are inserted into the transversal of hole Face is and the matched regular hexagon of the metal tube.

Further, the carbon fiber pipe is cylinder, it is entwined outside the metal tube by carbon cloth.

Further, being provided with one piece of height and the arc bound edge on the outer wall of the middle interconnecting piece of two parts The circular bosses of thickness matching have screw thread hole in the circular bosses；The arc bound edge, which corresponds to, is provided with appearance at the circular bosses The circular hole of the circular bosses insertion, after the arc bound edge is coated on the middle interconnecting piece of two parts, the circle Boss is located in the circular hole, then is locked into screw thread hole with bolt and fixes the two.

Compared with prior art, the utility model has the beneficial effects that the arc bound edge of 1. metal plate shells is solid using bolt It is scheduled in two parts of metal in skeleton, avoids and drill on carbon fiber pipe；2. skeleton uses the structure of four root canal part assembly, Easy to produce and assembling；3. inner layer metal pipe is designed to hexagonal structure, relative position that both pipe fitting is inserted into after two parts compared with For fixation, the position that adjustment pipe fitting and two parts is no longer needed in unit is locked automatically in subsequent bolt, it is raw convenient for the assembling of skeleton It produces.

Detailed description of the invention

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe.

Embodiment one

It is the skeleton of aero seat shown in Fig. 1, is square, passes through two parts, 2 head and the tail by four L shape pipe fittings 1 It interconnects.Every root canal part is made of the inner layer metal pipe 1a and outer layer carbon fiber pipe 1b that cross section is regular hexagon；Metal The both ends of pipe are exposed to outside carbon fiber pipe；Carbon fiber pipe is cylinder, is entwined outside metal tube by carbon cloth.Referring to figure 2, the interior insertion hole 2a with regular hexagon of two connectors of two parts, metal tube is fixed by bolts into after inserting in the hole.

It is metal plate shell shown in Fig. 3, the arc bound edge 3b bent downward including panel 3a and four.Metal plate is coated In the top of skeleton, four arc bound edges are respectively coated by its corresponding two parts, are locked into two parts finally by bolt Metal plate shell is connected with skeleton in middle interconnecting piece 2b.

Embodiment two

After the assembling of skeleton and metal plate shell generally uses production line, metal plate shell to be coated on skeleton, to be transferred to Subsequent processing is locked by automatic locking screw machine structure.Opposite position occurs in transfer process for metal plate shell and skeleton in order to prevent It moves, so the way of the present embodiment is as follows by Primary Location and fastening is carried out between metal plate shell and skeleton:

Referring to fig. 4, one piece of height and arc bound edge thickness matching are provided on the outer wall of the middle interconnecting piece 2b of two parts Circular bosses 2c, there is in circular bosses screw thread hole 2d.Referring to Fig. 5, arc bound edge correspond to be provided at circular bosses hold circular bosses insert The circular hole 3c entered, after arc bound edge is coated on the middle interconnecting piece of two parts, circular bosses are located in circular hole, then with bolt It is locked into screw thread hole and fixes the two.

Various modifications to these embodiments will be readily apparent to those skilled in the art, herein Defined General Principle can be real in other embodiments without departing from the spirit or scope of the present utility model It is existing.Therefore, the present invention will not be limited to the embodiments shown herein, and be to fit to it is disclosed herein Principle and the consistent widest scope of features of novelty.
