Description
Technical field
The utility model belongs to technical field of vehicle safety, particularly relates to a kind of seat of novel anti-whiplash injury.
Background technology
Whiplash injury is a kind of cervical injuries causing front truck driver and conductor to occur due to car rear-end front truck.When rear-end collision occurs, because collision can make front truck move forward rapidly, now trunk also can move forward along with car body, but head is relative with neck free, just can fall behind in effect of inertia head portion, thus cause head and the displacement of neck occurred level, cause the generation of whiplash injury.
In order to prevent the generation of whiplash injury as much as possible; person skilled devises many for preventing seat and the chair headrest of whiplash injury; these seats and chair headrest; what have is difficult to carry out because of complex structure; what have can only single use because Self-ruined design, and cannot repeated usage, and what have makes its protective capability poor because response action is delayed; therefore, practical application effect is not very desirable.
Chinese patent 201410784851.X discloses a kind of seat that can prevent whiplash injury, and it can realize the effect preventing whiplash injury substantially, but its structure and result of use still have much room for improvement and improve part.
Utility model content
For prior art Problems existing, the utility model provides a kind of seat of novel anti-whiplash injury, and its structure is simple and easy to implement, and action response speed is fast, and timely protective capability is strong, and can repeated usage.
To achieve these goals, the utility model adopts following technical scheme: a kind of seat of novel anti-whiplash injury, comprise base, backrest and headrest, described headrest comprises pillow and pillow frame, pillow relatively can be rested the head on frame and move forward and backward, pillow frame is fixedly installed on backrest top, is characterized in: the driving compartment of described base relative vehicle can move forward and backward; Backrest is arranged on base by recliner, is also provided with buffering energy-absorbing damping resilience unit between described base and backrest; Be connected by the first guide rail sliding chute between pillow with pillow frame, pillow is driven by pinion and rack, and its middle rack is fixedly installed on pillow frame top, and gear is arranged on pillow, and wheel and rack matches, and gear is by the first driven by motor.
Described base is arranged on seat support by the second guide rail sliding chute, and seat support is fixed on vehicular drive ceiling board.
Described buffering energy-absorbing damping resilience unit comprises some Liquid and gas dampers and fixing Kato part, Liquid and gas damper is arranged on base by fixing Kato part, the recliner of the lower end of backrest is fixedly connected with dash plate, piston rod and the dash plate of Liquid and gas damper are hinged, described fixing Kato part is connected with base by bolt, base is provided with bar shaped bolt mounting groove, and bolt is positioned at bar shaped bolt mounting groove.
Described Liquid and gas damper can be replaced the water bumper and gas spring that are set up in parallel.
The beneficial effects of the utility model: the seat speed of response of anti-whiplash injury of the present utility model is faster; Armchair structure is simple, degree of freedom is many, thus better by the protected effect of seat during rear-end collision in generation, and can repeated usage.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1,2,3, 4, a kind of seat of novel anti-whiplash injury, comprise base 3, backrest 1 and headrest, described headrest comprises pillow 2 and pillow frame 13, pillow 2 relatively can be rested the head on frame 13 and move forward and backward, pillow frame 13 is fixedly installed on backrest 1 top, and the driving compartment of described base 3 relative vehicle can move forward and backward; Backrest 1 is arranged on base by recliner 5, is also provided with buffering energy-absorbing damping resilience unit between described base 3 and backrest 1; Be connected by the first guide rail sliding chute 12 between pillow 2 with pillow frame 13, pillow 2 is driven by pinion and rack, and tooth bar 11 is fixedly installed on pillow frame 13 top, and gear 10 is arranged on pillow 2, and gear 10 matches with tooth bar 11, and gear 10 is driven by the first motor 9.
Described base 3 is arranged on seat support 7 by the second guide rail sliding chute 6, and seat support 7 is fixed on vehicular drive ceiling board.
Described buffering energy-absorbing damping resilience unit comprises some Liquid and gas dampers 4 and fixing Kato part, Liquid and gas damper 4 is arranged on base by fixing Kato part, the recliner 5 of the lower end of backrest 1 is fixedly installed dash plate 8, piston rod and the dash plate 8 of Liquid and gas damper 4 are hinged, described fixing Kato part is connected with base by bolt, base is provided with bar shaped bolt mounting groove, and bolt is positioned at bar shaped bolt mounting groove.
Described Liquid and gas damper 4 can be replaced the water bumper and gas spring that are set up in parallel.
Below in conjunction with accompanying drawing, a use procedure of the present utility model is described:
Vehicle of the present utility model is installed, in normal driving process, if the super sonic tachogenerator of vehicle tail detects that rear car has the possibility that knocks into the back, the first motor 9 in very first time pillow 2 will respond fast, driven gear 10 rotates, pillow 2 is stretched out forward fast, when after pillow 2 contact head, first motor 9 stops immediately, when rear-end impact occurs, stretch out due to pillow 2 distance reduced between headrest and head, and then reduce the horizontal displacement of head and neck, that reduces head gets rid of whip effect backward.If rear-end impact does not occur, through after a period of time, the first motor 9 drives pillow 2 automatically to return initial position, achieves reusable object, because the speed of response of pinion and rack is very fast, thus adds safety.
While rear-end impact occurs, under effect of inertia, human body back can produce an application force backward to backrest 1, and yaw displacement is produced between base 3 and backrest 1, owing to being connected to Liquid and gas damper 4 between base 3 and backrest 1, during beginning, backrest 1 pair of Liquid and gas damper 4 carries out compression, but be subject to the buffering energy-absorbing function of Liquid and gas damper 4, reduce deflection kinetic energy and the deflection speed of backrest 1, resilience is started after backrest 1 reaches tilt limit, but be subject to the shock damping action of Liquid and gas damper 4, again reduce the rebound velocity of backrest 1, thus, what reduce head gets rid of forward whip effect.Recliner 5 and the second guide rail sliding chute 6 add the degree of freedom of backrest 1 and base 3, add buffer distance, and make vehicle by the process of knocking into the back, the damage that passenger is subject to is down to minimum.
Through by the active protection of headrest before knocking into the back, by buffering energy-absorbing damping resilience unit in the process of knocking into the back and the double protection of the passive protection of base that can move forward and backward, farthest prevent the generation of whiplash injury.
Scheme in embodiment is also not used to limit scope of patent protection of the present utility model, does not allly depart from the equivalence that the utility model does and implements or change, and is all contained in the scope of the claims of this case.
