The specific embodiment
Below in conjunction with accompanying drawing principle of the present invention, structure and working process are specifically described.
Fig. 1 is the integral structure scheme drawing of translational energy-absorbing seat that is used for the neck protection of rear-end impact, the last slide rail 4 that this translational energy-absorbing seat comprises chair headrest 1, Chair back 2, seat chair cushion 3, be connected with the automotive seat chair cushion, the glidepath 5 that is connected with automotive floor panel, the slideway lockable mechanism 6 and the seat position regulating handle 7 of adjusting seat front and back position; Described translational energy-absorbing seat also comprises rear-end impact translational energy-absorbing mechanism, and described translational energy-absorbing mechanism is installed in the below of seat chair cushion 3, and is arranged symmetrically in the both sides of seat; Each translational energy-absorbing mechanism comprises lock pin flat board 10, crooked steel disc cylinder 11, energy-absorbing steel disc 12, traction cylinder 14 and speed limit block 15.Fig. 2 a is the structural representation of the slideway part lock pin flat board of translational energy-absorbing seat, and crooked cylinder 11 of described steel disc and speed limit block 15 are fixed on the lock pin flat board 10, and crooked steel disc cylinder 11 is at the front end of lock pin flat board 10; Described speed limit block 15 is in the dead aft of traction cylinder 14, and described energy-absorbing steel disc 12 is placed on the top of lock pin flat board 10, and an end of energy-absorbing steel disc is walked around crooked steel disc cylinder 11 and linked to each other with traction cylinder 14, and the other end is unsettled; Described traction cylinder 14 is fixed on the slide rail 4, is provided with dull and stereotyped guide groove 9 on last slide rail 4, and an end of described lock pin flat board 10 is a guide block 18, and described guide block 18 is arranged in the dull and stereotyped guide groove 9, and lock pin flat board 10 can slide along dull and stereotyped guide groove 9.The two ends of dull and stereotyped guide groove 9 are provided with front limit piece 8 and back limiting stopper 13, described lock pin dull and stereotyped 10 and back limiting stopper 13 closed contacts.
The forward sight and the birds-eye view of seat slide structure when Fig. 3 and Fig. 4 are non-rear-end impact states.Seat locking and non-lockup state scheme drawing when Fig. 5 and Fig. 6 are non-rear-end impact states.By the lockup state (see figure 5), stir position control lever 7 to non-lockup state (see figure 6), at this moment, seat glidepath 5 and last slide rail 4 can slide relative, the occupant according to demand, forward or mobile backward seat to desired location, releasing position regulating handle is then regulated the slideway lockable mechanism 6 of seat front and back position and get back to lockup state under the effect of retracing spring 16.In the control process of position because back limiting stopper 13 restriction lock pin flat boards 10 move backward with respect to slide rail on the seat 4, and traction cylinder 14 by and the effect of the power of 15 of speed limit blocks, restriction lock pin flat board 10 travelling forward with respect to last slide rail 4.Like this, crooked steel disc cylinder 11, speed limit block 15, retracing spring 16 and the steel disc baffle plate 17 on lock pin dull and stereotyped 10 and the lock pin flat board all the time with seat on slide rail 4 move forward and backward synchronously together.
Seat is when non-serious rear-end impact; promptly normal seat position regulate and automobile front, side collision and slight situations such as rear-end impact under; when the slideway lockable mechanism 6 of adjusting position during at lock position; show as Fig. 5; the rear end of lock pin flat board 10 has the back limiting stopper 13 of enough rigidity and intensity by restriction; stop seat to front slide; avoided when head-on crash; moving forward of occupant and seat; when having guaranteed head-on crash; the rear-end impact translational energy-absorbing seat is the same with the general-utility car seat, can protect occupant's safety to a certain extent.Speed limit block 15 can provide the threshold value of certain power, and when the application force between speed limit block 15 and the traction cylinder 14 was lower than this threshold value, translational energy-absorbing mechanism can not come into force.Therefore when slight rear-end impact, speed limit block 15 stops sliding backward of slide rail 4 by the motion of the traction cylinder 14 that restriction and last slide rail 4 are connected mutually.
The side-looking of slideway part and the partial schematic diagram of Fig. 7 translational energy-absorbing seat.When the normal locking of the slideway lockable mechanism 6 of seat position adjustments, and the rear-end collision impact severity surpasses to a certain degree, when promptly traction cylinder 14 application forces that are connected when speed limit block 15 and last slide rail 4 surpassed speed limit block 15 preset threshold, translational energy-absorbing mechanism started.At this moment, lock pin dull and stereotyped 10 and last slide rail 4 can be realized slide relative by the dull and stereotyped guide groove 9 that is located on the slide rail 4; During slide relative, lock pin dull and stereotyped 10 links together with seat glidepath 5 by slideway lockable mechanism 6 lockings, and slide rail 4 slides backward relatively on the seat, thereby, realize that the relative automotive floor panel with the occupant of seat slides backward certain distance, as shown in Figure 8.
When translational energy-absorbing mechanism comes into force, slide backward in the process at seat and occupant, translational energy-absorbing mechanism provides certain comparatively stable constrained force to last slide rail 4, near platform power, thus the energy in the absorption portion collision, actv. protection occupant's neck.The constrained force that translational energy-absorbing mechanism provides is that the plastic deformation by translational energy-absorbing mechanism part parts realizes.The stabilised platform power that translational energy-absorbing mechanism obtains is to realize by the energy-absorbing steel disc 12 that traction cylinder 14 stretches on crooked steel disc cylinder 11, wherein crooked steel disc cylinder 11 is fixed on the lock pin flat board 10, can pass through bolted connection between traction cylinder 14 and the energy-absorbing steel disc 12, for guaranteeing in the whole endergonic process of steel bar, connection between energy-absorbing steel disc 12 and the traction cylinder 14 was not lost efficacy, need be in the area of contact that increases both connecting portions.The control of the size of constrained force is the size of the diameter of the thickness by energy-absorbing steel disc 12 is set and crooked steel disc cylinder 11 mainly, also can be by steel disc baffle plate 17 vertical distance apart from the center shaft of crooked steel disc cylinder 11 is set, regulate energy-absorbing steel disc 12 the go for a stroll angle of bending of bent steel disc cylinder 11 and the friction coefficient of the friction face between energy-absorbing steel disc 12 and the steel disc baffle plate 17.
The 11 rectangle steel discs that crack during speed limit block 15 adopts, the diameter of described traction cylinder 14 are greater than the slit of opening on the speed limit block 15, and plasticity or elastic deformation take place during described speed limit block 15 rear-end collisions.Speed limit block 15 is the mechanisms that the threshold value of certain force is provided, and the plastic deformation or the elastic deformation of the part material by translational energy-absorbing mechanism are realized.Wherein if plastic deformation takes place in speed limit block 15 when the threshold value of power is provided, then after translational energy-absorbing mechanism comes into force once, the speed limit block 15 that need more renew; If elastic deformation takes place when speed limit block 15 provides the threshold value of power, then after translational energy-absorbing mechanism was coming into force once, the speed limit block 15 that need not more to renew can continue to use.The threshold value of concrete power can be set by the thickness of gap width on the speed limit block 15 and speed limit block.The threshold value of power both can preestablish when producing seat, also can set by the dynamo-electric mechanism of a cover according to the actual conditions such as body weight of occupant on the seat.
The local enlarged diagram of energy-absorbing state during the slideway part rear-end collision of energy-absorbing view and translational energy-absorbing seat during the slideway part rear-end collision of Fig. 8 and Fig. 9 translational energy-absorbing seat.During rear-end impact, the back cunning of seat is subjected to the restriction of automobile interior space, particularly front-row seats, if the distance that slides backward is excessive, will cause automobile rear occupant's shank to be squeezed, thereby cause bigger damage.Therefore, interior space according to most of automobile, the bound of setting sliding distance is 150mm and 50mm, when seat slide into backward setting maximum apart from the time, lock pin flat board 10 stops seat and occupant's continuation to be moved backward by the front limit piece 8 with enough rigidity and intensity that restriction and last slide rail 4 are connected.
The back cunning that the stretch bending of translational energy-absorbing seat provided by the invention by steel bar is deformed into seat provides comparatively stable constrained force.When energy-absorbing seat is regulated at normal front and back position, need stir seat position regulating handle 7 and make chair slide lockable mechanism 6 transfer to the slide relative that non-lock position is realized seat glidepath 5 and last slide rail 4, and then realize the adjusting of the front and back position of seat.Seat is when non-rear-end impact, promptly normal seat position regulate and situations such as automobile front, side collision under, when the slideway lockable mechanism 6 of adjusting position during at lock position, the rear end of lock pin flat board 10 stops travelling forward of seat and occupant by the back limiting stopper 13 that restriction has enough rigidity and intensity.
When the application force of last slide rail and seat surpasses preset threshold, just think that rear-end impact is more serious, need to start translational energy-absorbing mechanism.During non-serious rear-end impact, speed limit block 15 limits sliding backward of slide rail by the motion of the traction cylinder 14 that restriction and last slide rail are connected mutually.When the rear-end impact generation that surpasses to a certain degree, chair slide lockable mechanism 6 still is in lock position, and lock pin dull and stereotyped 10 and last slide rail 4 can be realized slide relative by the dull and stereotyped guide groove 9 that is located on the slide rail.During slide relative, lock pin dull and stereotyped 10 links together with seat glidepath 5 by chair slide lockable mechanism locking, and slide rail slides backward relatively on the seat.Chair headrest 1, Chair back 2, the relative automotive floor panel with the occupant of seat chair cushion 3 slide backward certain distance.When translational energy-absorbing mechanism comes into force, seat can only move the distance that is no more than setting backward, concrete position limit is to realize by front limit piece 8, after last slide rail is with respect to glidepath slide relative certain distance, lock pin flat board 10 limits seat and occupant's continuation and moves backward by the front limit piece 8 that restriction has enough rigidity and intensity.
The distance that the size of threshold value and constrained force and seat slide backward can preestablish when chair mounted; also can be by the technology of active safety; body weight according to the occupant on the seat; the order of severity of information such as sitting posture and possible rear-end impact; increase or reduce the threshold value of speed limit block by the dynamo-electric mechanism of a cover; regulate the angle of bend of energy-absorbing steel disc 12 and the diameter of the crooked steel disc cylinder cylinder 11 on the lock pin flat board 10; and the realizations such as distance between adjusting steel disc block 17 and crooked steel disc cylinder cylinder 11 line of centerss are to the control of constrained force size; simultaneously; can set slide rail distance relatively backward, realize neck better protection the occupant.
