Description
The present invention relates to the anti-inertia and the centnifugal force field of automobile, particularly a kind of automobile inertial, centrifugal force energy safety seat capable of reducing.
Automobile is in running at high speed, in case when sudden stop or collision incident occurring, powerful inertia energy is easy to the people is thrown away forward, causes huge safety hazard.To this, people have invented safety strap and safety air bag.The effect of safety strap is in the moment of sudden stop or collision human body is on the seat spacing, but shortcoming be head sometimes still can go out forward at a high speed with operator's compartment in certain part bump against; The effect of safety air bag is at the moment airbag inflation of colliding, and gives human body head with enough bufferings, and air bag is lost heart, and suffocates to avoid human body.But problem exactly just is on the dependency structure that moment loses heart, external existing numerical example causes the incident of death by suffocation because of air bag safe in utilization, and mainly concentrate on one's body the elderly, this anaerobic exercise ability that reflects the elderly is relatively poor, and safety air bag has certain technical limitation to this.Simultaneously, should it should be noted that bringing a high price of safety air bag in the market, easily circles up to ten thousand, and the problem that safety air bag solved mainly only be to cushion collide the moment human body head before hit, this constitutes one group of contradiction with the megatrend that customer in the market requires domestic automobile significantly to make a price reduction.If we can be from other angle solution simple in structure, with low cost " the moment human body head of colliding before hit " problem, promptly try every possible means inertia energy is cut out, that is petty, and one can be used as the anti-inertia safety device that low-grade automobile substitutes safety air bag, they are two years old, for high-grade automobile, safety air bag both had been installed, this anti-inertia safety device is installed again, also in having loaded onto double insurance for high-grade automobile, the meaning of its defendance human body safety is very huge to this nothing.
Simultaneously, general automobile is when turning, and we once realized the sort of tangible centrifugal action, and promptly human body is toppled over along the outside of turn direction, needs the very big strength of expense to adhere to body gesture is maintained the harm of centnifugal force when this also reflects automobile turning.To this, think like this in the Chinese patent " a kind of automotive seat that centripetal acceleration can be provided automatically " (number of patent application 96229859) and " the utility model discloses a kind of automotive seat that centripetal acceleration can be provided automatically; it comprises seat cushion, the backrest of seat and can make slide rail that seat moves forward and backward etc.; it is characterized in that: below the seat cushion of seat; two arc-shaped guide rails side by side have been installed; make seat when automobile turns round; be subjected to centrifugal action, can slide along arc-shaped guide rail, thereby provide a suitable centripetal acceleration automatically for the occupant.Whole seat links to each other with arc-shaped guide rail through four supporting wheels, and its contact surface is in the shape of the letter V.The automatic safe button is equipped with at the arc-shaped guide rail two ends.The utility model mainly is applicable to vehicular traffic, particularly roadlice.It is more comfortable that it is taken." shortcoming of this invention is; arc-shaped guide rail is in case after installing; seat institute can slidable direction just determine; be that seat can only produce displacement according to set direction; no matter and automobile is being done the motion of which kind of direction; that is to say that it solved can only be wherein a kind of of inertia energy or centrifugal force energy, and do not possess commonality widely.
The objective of the invention is to develop a kind of safety seat that will influence the automobile urgent brake car or cause when colliding the inertia energy of significant damage to subdue automatically; centrifugal force energy when it simultaneously also should be able to be with automobile turning is subdued automatically; when this device and safety strap are used; the protective effect of alternative safety air bag, thus member's personal safety effectively protected.
The object of the present invention is achieved like this.The present invention includes every basic structure of general-utility car seat, seat cushion as seat, backrest, the slide rail that seat is moved forward and backward, the control seat is along the control setup of slide rail slip and the device at adjustment chair back angle of inclination etc., it is characterized in that: under common seat cushion, part on the slide rail is divided into movable bonded assembly two parts, be chair seat board and seat support body, the flexible connection of chair seat board and backrest intercropping tiltable angle, seat support body and slide rail intercropping controollable sliding block joint, the lower end of chair seat board has rigidly fixed hemisphere, inlay on the hemispheroidal sphere many group cardan wheels are installed, each is organized cardan wheel and is evenly distributed as symmetry on the hemisphere sphere, described seat support body is the inner rigid body of hemispherical groove that is, hemisphere can slide around arc by cardan wheel all directions along hemispherical groove walls in the hemispherical groove of its lower end, be connected and fixed by many groups connecting device between chair seat board and the seat support body, described connecting device is by universal-joint, piston and piston rod etc. interconnect composition, there is a universal-joint at the two ends of every group of connecting device upper piston and piston rod, make this group connecting device and chair seat board and seat support body be rigidly connected fixing by the two universal-joints other end separately again.
After implementing aforesaid way, automobile is when turning, and chair seat board and human body upwards slide around arc along hemispherical groove automatically along the direction of centnifugal force synchronously, thereby for the occupant provides a suitable centripetal acceleration automatically, centnifugal forceization are gone; Automobile is when sudden stop, and chair seat board and human body upwards slide around arc along hemispherical groove automatically along the direction of force of inertia synchronously, by centripetal acceleration provide automatically and the distortion of piston inner spring after pulling force, centnifugal forceization is gone.
As a kind of improvement of the present invention, described connecting device has three groups, and the angle of respectively organizing on its virtual extended line between the connecting device equates.Like this, both saving in material can make the flexible connection between chair seat board and the seat support body keep balance again.
As a kind of improvement of the present invention, described cardan wheel is not for there being axle ball cardan wheel.Like this, can obtain better rolling effect.
As a kind of improvement of the present invention, its cross section, the lower end of described chair seat board is shown as
Shape like this, can make chair seat board with respect to the seat support body moving in a big way can be arranged.
As a kind of improvement of the present invention, described hemisphere inner hollow, or with more cheap lightweight material, as filling hollow spaces such as air tyre body structures, like this, both saving in material, cost-cutting can make the weight of seat greatly reduce again.
As a kind of improvement of the present invention, described piston is a dashpot piston.By the damping effect of control dashpot piston, thus can make chair seat board more slick and sly with respect to the motion of seat support body, alleviate noise.
Below in conjunction with accompanying drawing the present invention is done explanation in further detail.
Accompanying drawing 1 is an External view of the present invention, and cardan wheel adopts common form.
Accompanying drawing 2 is External views of the present invention, and cardan wheel is not have axle ball cardan wheel.
In above each width of cloth figure, (1) is seat cushion, and (2) are backrests, (3) be chair seat board, (4) be the seat support body, (5) are hemispheres, and (6) are cardan wheels, (7) be the ball that does not have on the axle ball cardan wheel, (8) be hemispherical groove, (9) are connecting devices, and (10), (11) are universal-joints, (12) be piston, (13) are piston rods.
As accompanying drawing 1 and accompanying drawing 2 findings, the present invention is actually the part under the general-utility car seat cushion (1), on the slide rail is divided into movable bonded assembly two parts, be chair seat board (3) and seat support body (4), other parts as for the general-utility car seat, control setup that slides along slide rail as slide rail that seat is moved forward and backward, control seat and the device of adjusting chair back angle of inclination etc., do not draw in two figure, this mainly is to be the succinct cause of drawing.As can be seen from Figure, its cross section display shape of the lower end of chair seat board (3) is
In fact its cross section display shape of the lower end of chair seat board (3) also can be basic oblong, but like this, please note, after chair seat board (3) is with respect to seat support body (4) inclination certain angle, the upper limb of seat support body (4) will limit chair seat board (3) and do further to tilt, and chair seat board (3) is very limited with respect to the slant range of seat support body (4), so, as preferred forms, adopt
The following end section of the chair seat board of shape (3).As can be seen from Figure, to influence the automobile urgent brake car or the agent structure of the safety seat that the inertia energy that work the mischief when colliding and the centrifugal force energy during with automobile turning are subdued automatically mainly is hemisphere (5) as the present invention, cardan wheel (6), the structure design that hemispherical groove (8) is formed, because the lower end of chair seat board (3) has rigidly fixed hemisphere (5), many group cardan wheels (6) are installed on the sphere of hemisphere (5), each is organized cardan wheel (6) and is evenly distributed as symmetry on the sphere of hemisphere (5), seat support body (4) is the inner rigid body of hemispherical groove (8) that is, hemisphere (5) can slide around arc along all directions of hemispherical groove walls in the hemispherical groove (8) of its lower end by cardan wheel (6), be connected and fixed by many group connecting devices (9) between chair seat board (3) and the seat support body (4), like this, chair seat board (3) is with respect to forming a kind of situation that cardan wheel (6) can slide relative of utilizing between the seat support body (4), the scope of sliding is in the shape of hemispherical groove (8), and the direction that slip can be done to adapt to therewith according to the difference of inertia and centrifugal force energy direction in hemispherical groove (8) is moved.Sudden stop takes place, when collision or automobile turning, because human body is strapped on the backrest (2) with safety strap, and the flexible connection of chair seat board (3) and backrest (2) intercropping tiltable angle, seat support body (4) and slide rail intercropping controollable sliding block joint, like this, when seat support body (4) is controlled with respect to the slip of slide rail, under the effect of inertia energy and centrifugal force energy, seat support body (4), slide rail and automobile bodies ground are equivalent to constitute an immovable integral body, and the fabricate block that is constituted between chair seat board (3) and backrest (2) will do to adapt to the motion of inertia and centrifugal force energy direction with respect to the seat support body (4) that is fixed, at this moment, the effect of hemispherical groove (8) performance standard sense of motion, thereby produce the suitable centripetal acceleration that adapts of sense of motion therewith automatically, thereby the further performance effect of subduing inertia and centrifugal force energy.
In accompanying drawing 1 and accompanying drawing 2, we it can also be seen that, be connected and fixed by many groups connecting device (9) between chair seat board (3) and the seat support body (4), each group connecting device (9) is by universal-joint (10), (11), piston (12) and piston rod (13) such as interconnect at composition, there is a universal-joint (10) at the two ends of every group of connecting device (9) upper piston (12) and piston rod (13), (11), again by two universal-joints (10), (11) other end separately makes this group connecting device (9) and chair seat board (3) and seat support body (4) be rigidly connected fixing, connecting device (9) has three groups, and the angle of respectively organizing on its virtual extended line between the connecting device equates.Why to adopt two universal-joints (10), (11), mainly be because because hemispherical groove (8) is being brought into play the effect of standard sense of motion, so in fact, chair seat board (3) belongs to the 3 D stereo motion with respect to the motion of seat support body (4), when this three-dimensional motion takes place, piston rod (13) on the connecting device (9) of a certain group or two groups is made extensional motion with respect to piston (12), and the piston rod (13) on the connecting device (9) of other two groups or a group may be made contractile motion with respect to piston (12), this is embodying the characteristic of this motion on the one hand, on the other hand, because piston rod (13) may not be that petty slyness with respect to the stretching or the contractile motion of piston (12), may also have either large or small noise, therefore, piston (12) is adopted to dashpot piston here, the principle that general dashpot piston is adopted gives bumper and absorbing shock for utilizing the piston inner fluid to spray from the oilhole high speed, like this, might be because the oilhole bore be too small, cause piston rod (13) slow excessively with respect to the stretching or the contractile motion speed of piston (12), thereby have influence on the effect that the present invention subdues inertia and centrifugal force energy, therefore, it is big slightly that oilhole in this dashpot piston (12) can be done, so that performance makes chair seat board more slick and sly with respect to the motion of seat support body on the basis that does not influence the ability of subduing, alleviate the effect of noise.
In the present invention, chair seat board (3) is with respect to the motion amplitude of seat support body (4), be subjected to piston rod (13) on the one hand with respect to the stretching of piston (12) or the restriction of contraction amplitude peak, can also be subjected to chair seat board (3) on the other hand with respect to seat support body (4) influence of maximum relative displacement in the vertical itself, by regulating this two parameters, just can control the largest motion amplitude of chair seat board (3) with respect to seat support body (4).After adopting above structure design, be sitting on the seat, even if do not have sudden stop, the generation of collision and turning situation, seat itself just can have certain angle of inclination, might people not just can not find this seat seat like this, needn't worry in fact, because automobile urgent brake car, inertia or centrifugal force energy when colliding and turning are generally much bigger than human weight, by the elastic parameter of control dashpot piston (12) inner spring and the size of oilhole, we can guarantee seat or difficult inclination at ordinary times fully, perhaps allow inclination by a small margin, be that the angle of inclination can not reach maxim, and have only the huge energy of inertia or centnifugal force just the angle of inclination of seat can be reached maximum.
In the present invention, if hemisphere (5) inside is not hollow, be that hemisphere (5) is a solid, that is petty, advantage is to make the center of gravity of seat on the low side, but the shortcoming too heavy and bad installation of cardan wheel (6) that is seat, this is not inconsistent with the light-duty trend of present pursued vehicle, therefore, we adopt hemisphere (5) inner hollow or with more cheap lightweight material, as air tyre body structure etc. fill hollow space way in case expendable weight also should be noted that simultaneously, by the volume of control hollow space, we just can search out an equilibrium point between the weight of the center of gravity of controlling seat and seat.
We notice, so the difference of accompanying drawing 1 and accompanying drawing 2 is adopting common cardan wheel (6) still to adopt inside to be distributed with the no axle ball cardan wheel (6) of ball (7), as preferred forms, cardan wheel (6) is not have axle ball cardan wheel, and preferably do not have axle ball cardan wheel and adopt netted many pearls of shape multi-turn cloth pearl structure, like this, both obtained good rolling effect, and avoided the problem at the stressed dead angle of ball (7), also make manufacturing of the present invention comparatively cheap.
In the present invention, the effect of slide rail is similar substantially to prior art, mainly is to make the rapid rollback of seat in the moment of colliding, return back to certain limit after, the present invention begins further performance and subdues action of inertia.
