The railroad of automotive seat
Technical field
The utility model relates to a kind of railroad of automotive seat, and it mainly is applicable to the all-cis V348 commercial vehicle of Ford, belongs to the automotive trim field.
Background technology
In the prior art, when the installing space of automotive seat hour, generally be difficult to design the lifter of elevating function before and after having, and the stepless slide rail of belt lifting mechanism uses seldom especially in automotive seat.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of railroad of automotive seat, and it has the stepless slide rail function of belt lifting mechanism.
The technical scheme in the invention for solving the above technical problem is: the constructional feature of this railroad is that it mainly is made up of left slide track component, right slide track component, slide rail handle, lifting mechanism assembly, connecting rod, lifting spring, locking torsion spring, big slide rail, little slide rail, fluid column retainer, clamp shifting block, bundle assembly and long handle bar, short handle bar; Left side slide track component, right slide track component symmetry are installed, be connected with the slide rail handle by the lifting mechanism assembly, the locking torsion spring set is on connecting rod, the fluid column retainer is installed in the centre of big slide rail and little slide rail, on clamp shifting block and big slide rail, clamp is housed and the steel wire that resets respectively, bundle assembly is installed on lifting mechanism assembly and long handle bar, the short handle bar, and long handle bar, short handle bar then are installed in and separate on the lock support.
The utility model also is provided with fixed cover, separates retainer and connecting strap; Fixed cover is enclosed within on connecting rod and the locking torsion spring, and the release snare is on the locking torsion spring, and connecting strap and fixed cover weld.
The utility model compared with prior art has the following advantages and effect: reasonable in design, novelty, and simple, convenient, can realize the locking of slide rail, and can realize the front and back lifting of lifter to have market outlook preferably.

The specific embodiment
Referring to Fig. 1~Fig. 5, the utility model mainly is made up of left slide track component 1, right slide track component 6, slide rail handle 3, lifting mechanism assembly 4, connecting rod 7, lifting spring 9, locking torsion spring 12, big slide rail 15, little slide rail 17, fluid column retainer 19, clamp shifting block 20, bundle assembly 23 and long handle bar 26, short handle bar 27.Left side slide track component 1, right slide track component 6 symmetries are installed, be connected with slide rail handle 3 by lifting mechanism assembly 4, locking torsion spring 12 is enclosed within on the connecting rod 7, fluid column retainer 19 is installed in the centre of big slide rail 15 and little slide rail 17, on clamp shifting block 20 and big slide rail 15, the clamp 21 and the steel wire 22 that resets are housed respectively, bundle assembly 23 is installed in lifting mechanism assembly 4 and long handle bar 26, on the short handle bar 27, and long handle bar 26,27 on short handle bar is installed in to be separated on the lock support 25, fixed cover 11 is enclosed within on connecting rod 7 and the locking torsion spring 12, separate retainer 13 and be enclosed within on the locking torsion spring 12, connecting strap 14 and fixed cover 11 welding; In addition, left side safety strap adapter plate assembly 2 bolt ups are on left slide track component 1, and right safety strap adapter plate assembly 5 bolt ups are on right slide track component 6, cushion block 8 is enclosed within on the connecting rod 7,10 of linings are enclosed within on the connecting strap 14, slide core 16 is contained on the big slide rail 15, and fluid column 18 is contained on the fluid column retainer 19, on long handle bar 26 and short handle bar 27 extension spring 24 is installed also.
Left side slide track component 1, right slide track component 6 left-right symmetric are connected with slide rail handle 3 by lifting mechanism assembly 4.During use, upwards lift slide rail handle 3 drive clamp shifting blocks 20 and clamp 21 and move down, make clamp 21 break away from little slide rail 17, big slide rail 15 and little slide rail 17 move forward and backward under the rolling of roller.When unclamping slide rail handle 3, clamp shifting block 20 and clamp 21 move on resetting under the effect of the steel wire 22 that resets, and clamp 21 is stuck in the profile of tooth of big slide rail 15 and little slide rail 17 simultaneously, and big slide rail 15 and little slide rail 17 are become one, thereby realize the locking of slide rail.
Two lifting mechanism assemblies 4 interconnect and are fixed on left slide track component 1, the right slide track component 6, the elevating function before and after can realizing respectively.Rotating short handle bar 27 drives bundle assemblies 23, separates retainer 13 and with locking torsion spring 12 it is separated with connecting rod 7, under the mutual action of lifting spring 9 and human body self gravity, connecting rod 7 and connecting strap 14 can stretch mutually, make the purpose that circular movement is realized lifting thereby connecting rod 7 drives rocker arm assembly.When unclamping short handle bar 27, locking torsion spring 12 returns and connecting rod 7 are held tightly, and connecting rod 7 becomes one with connecting strap 14, realizes anterior lifting locking; In like manner, long handle bar 26 is used to control the elevating function at rear portion, rotates and unclamp the lifting and the lockings at 26 realizations of long handle bar rear portion.
