Automotive seats shock absorption device
Technical field
The present invention relates to a kind of automobile seat for child.
Background technology
In prior art, when automobile seat for child is installed to and uses on seat in automobile, automotive seats is fixed relatively conventionally, and what when the accident such as bumping, play cushioning effect is the safety strap tying up on automobile seat for child.But safety strap only can play to the children in automotive seats bumper and absorbing shock protective effect, and automotive seats itself is shielded hardly.In general, automobile seat for child comprises seat and the base being fixed together, in actual applications, when bumping, seat due to inertia can be relative base swing, this makes connection location between seat and base easily produce distortion even to rupture.
Summary of the invention
The technical problem to be solved in the present invention is to provide the automotive seats shock absorption device that a kind of seat to automotive seats plays shock-absorbing protecting.
For solving the problems of the technologies described above, the invention provides a kind of automotive seats shock absorption device, it comprises seat, is positioned at under-seat and seat formed to the base supporting, seat bottom has relative two side ends, wherein a side is connected in base rotationally, and another side is free end, between seat and base, is provided with energy-absorbing material, at the relative base of free end of seat bottom, do convergence motion and during extruding energy-absorbing material, energy-absorbing material can produce deformation.When automobile meets with collision or sudden stop, seat is because inertia can swing by relative base, and the free end of seat moves downward, and energy-absorbing material is extruded and produces deformation, so that shock absorbing effect to be provided.
Further, seat comprises seat body, is removably connected in the framework of seat body bottom, and seat is connected with base by framework, and energy-absorbing material is arranged between framework and base.Seat adopts the split-type structural of seat body and framework, is convenient to dismounting, maintenance and changes separately framework.
Further, be provided with deck in seat body, be provided with buckle on framework, seat body is coordinated mutually and is removably connected with the grafting of buckle by deck with framework.
In a kind of specific embodiment, the bottom of seat has pressing plate, and seat is connected with base by pressing plate, and energy-absorbing material is arranged between pressing plate and base.Seat adopts monolithic construction, and the pressing plate of its bottom both facilitated relative to base and rotates, and can contact well with energy-absorbing material again.
In a kind of preferred embodiment, be arranged in the two side ends of seat bottom, free end is positioned at front side, and a side that is connected in base is positioned at rear side.Here and herein other everywhere so-called " front " and " afterwards " according to actual use habit, define, the direction that the interior children of seat face is " front ", the direction that the interior children of seat carry on the back court is " afterwards ".When bumping, seat can lean forward, and the free end that is positioned at front side can move down, thereby compression energy-absorbing material makes it distortion and generation shock absorbing effect.
Preferably, energy-absorbing material can be arranged between the free end of seat bottom and the base below free end.
In a kind of specific embodiment, energy-absorbing material is foam metal.
More specifically.Energy-absorbing material is foamed aluminium.
Scope of the present invention, is not limited to the technical scheme that the particular combination of above-mentioned technical characterictic forms, and also should contain by above-mentioned technical characterictic or its equivalent feature and carry out combination in any and other technical scheme of forming simultaneously.The technical characterictic that has a similar functions such as disclosed in above-mentioned feature and the application (but being not limited to) is replaced mutually and technical scheme of forming etc.
Because technique scheme is used; the present invention compared with prior art has following advantages: seat and base adopt rotating connection mode; when bumping; the relative base of seat is done lever motion; make the energy-absorbing material between seat and base be extruded distortion; to produce buffering and damping effect, thereby provide protection to the children in seat and seat.

The specific embodiment
Below in conjunction with accompanying drawing, several preferred embodiments according to the present invention are described in detail.
Embodiment 1
Device as Figure 1-4, comprise seat 1, be positioned at seat 1 below and seat 1 is formed to the base 2 supporting, seat 1 bottom has relative two side ends, wherein a side is connected in base 2 rotationally by rotational pin 3, another side is free end, between seat 1 and base 2, is provided with energy-absorbing material 4.
In this example, be arranged in the two side ends of seat 1 bottom, free end is positioned at front side, and a side that is connected in base 2 is positioned at rear side, and this is optimal way.In addition, energy-absorbing material 4 can be arranged between the free end and the base below free end 2 of seat 1 bottom, can certainly be arranged between other position and base 2 of seat 1 bottom.
Energy-absorbing material 4 is known materials, and existing energy-absorbing material has a variety of, and such as foam metal etc., the present invention preferably adopts foamed aluminium as energy-absorbing material 4.When the relative base 2 of free end of seat 1 bottom is done convergence motion and during extruding energy-absorbing material 4, described energy-absorbing material 4 can produce deformation, to provide shock absorbing effect to seat 1.
In embodiment shown in Fig. 1-4, seat 1 comprises seat body 11, is removably connected in the framework 12 of seat body 11 bottoms, and seat 1 is connected with base 2 by described framework 12, and energy-absorbing material 4 is arranged between framework 12 and base 2.
Particularly, be provided with deck 111 in seat body 11, be provided with buckle 121 on framework 12, seat body 11 is coordinated mutually and is removably connected with the grafting of buckle 121 by deck 111 with framework 12.
Under the preferred structure condition adopting at the present embodiment, when automobile bumps or during sudden stop, seat 1 can lean forward relatively, the free end that is positioned at front side can press down, and makes the compressed distortion of energy-absorbing material, thereby produces damping, buffering effect.
Embodiment 2
Shown in Fig. 5, the present embodiment and embodiment discussed above 1 structural similitude, difference is: seat 1 does not adopt split type structure, but adopts seat 1 bottom with the monolithic construction of pressing plate 10.
As shown in Figure 5, the front end of pressing plate 10 is free end, and the rear end of pressing plate 10 is rotated and is connected by rotational pin 3 with base 2, and the front end of pressing plate 10 is free end.Energy-absorbing material 4 is arranged between pressing plate 10 and base 2, and preferably as shown in Figure 5, is arranged between free end and the base 2 of free end below.
The operating principle of the present embodiment is identical with embodiment 1 with mode, and still, difference is that the seat in the present embodiment can not be split under normal circumstances itself, thereby the suppleness of pressing plate 10 and firmness are had to certain practical application request.
As mentioned above, we are illustrated according to aim of the present invention completely, but the present invention is not limited to above-described embodiment and implementation method.The practitioner of correlative technology field can carry out different variations and enforcement in the scope of technological thought license of the present invention.
