Specific embodiment
The technical scheme of this patent is described in more detail with reference to specific embodiment.
Refer to Fig. 1, a kind of drive-by-wire chassis, including base plate 1, sliding seat 2, rivet 4, locking pin 5, locking torsion spring 6, bracing wire
Cable wire 9 and fixed seat 11, the sliding seat 2 are rotated with base plate 1 by rivet 4 and are connected, and the two ends of rivet 4 are provided with bushing 3, are reduced
Circular hole A, the He of sliding seat 2 are provided with friction between sliding seat 2 and base plate 1, fixed fixed seat 11 in sliding seat 2, fixed seat 11
The correspondence position of base plate 1 is respectively equipped with size identical circular hole B and circular hole C, and locking pin 5 passes through fixed seat 11, sliding seat 2 and bottom
Plate 1；One end of the locking pin 5 is provided with circular hole, locks one end of torsion spring 6 through the circular hole of the end of locking pin 5, locks torsion spring 6
It is connected in sliding seat 2 by lock-screw 8 with reduction torsion spring 7, one end of reduction torsion spring 7 is installed in the side of fixed seat 11
On；The bracing wire cable wire 8 catches on the other end of locking torsion spring 6 and reduction torsion spring 7, and one end of bracing wire cable wire 8 stretches out and contracts
Enter to be installed in the line traffic control bracing wire 10 of the side of fixed seat 11.
The locking pin 5 is provided with step at the inner side of fixed seat 11, is propped up admittedly by step when integrated model is locked
Reservation 11 is realized, to the spacing of locking pin motion, when integrated model unlocks, activity being propped up by the end of locking pin 5
The madial wall of seat 2 is realized to the spacing of the motion of locking pin 5.
The locking pin 5 is multi-diameter shaft, and the diameter of axle of fixed locking torsion spring 6 one end is less than the other end diameter of axle, in integrated machine
When structure is locked, locking torsion spring 6 is against in fixed seat 11, the motion of locking pin 5 is carried out spacing；When integrated model unlocks
When, realized to the spacing of the motion of locking pin 5 by the ladder of locking pin 5 and the contact of fixed seat 11.
The locking pin 5 is that section is circular axle or square, rectangle, a kind of pin of kidney-shaped, it is ensured that sliding seat 2, solid
Reservation 11 and the corresponding hole shape of base plate 1 are consistent with locking pin 5.
The circular hole B of correspondence locking pin 5 is flange circular hole in the sliding seat 2, improves the stationarity of the motion of locking pin 5.
Flange is provided with the position of the both sides correspondence sliding seat 2 of the base plate 1, the bulk strength of base plate 1 is lifted.
Operation principle of the present utility model is：When control is connected to the line traffic control handle of the other end of line traffic control bracing wire 10, pulls and draw
During the 9 retraction line traffic control bracing wire 10 of line cable wire, bracing wire cable wire 9 drives locks the side of torsion spring 6 and the side of reduction torsion spring 7 with locking screw
Nail 8 rotates for axle, and the opposite side for locking torsion spring 6 drives locking pin 5 to be slided in circular hole A, when the inside retraction of locking pin 5 extremely
During the inner side of base plate 1, sliding seat 2 and base plate 1 are unlocked state, and reclining function is opened, when locking is needed, control line
The line traffic control handle of the other end of bracing wire 10 is controlled, external force on bracing wire cable wire 9 disappears, reduction torsion spring 7 torsion of itself is about lock
Tight screw 8 is rotated, and bracing wire cable wire 9 is pulled out into line traffic control bracing wire 10, while driving locking torsion spring 6 to rotate together, produces locking torsion spring 6
Raw torsion, locking torsion spring 6 drives the circular hole C that locking pin 5 is stretched out on the outer insertion base plate 1 of sliding seat 2, mechanism's locking；In this mistake
Cheng Zhong, if base plate pushes down locking pin 5, locking pin 5 will not be locked the drive of torsion spring 6, it is necessary to which release could drive, this
Setting be when can make user against chair back, even if others or oneself accidentally switch is opened, will not also make mechanism
Unclamp and cause the accident, it is necessary to which user leaves at back the chair back and can just realize adjustment function, safe and practical.
The better embodiment to this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, in the ken that one skilled in the relevant art possesses, can also be on the premise of this patent objective not be departed from
Make a variety of changes.
