Description

Towel bar assembly capable of preventing misuse and starting interference easily
Technical Field
The invention relates to the technical field of seats, in particular to a towel bar assembly capable of preventing misuse and starting interference due to easy access.
Background
After the seat with the seat cushion folding easy-entry function is started and the seat cushion folding function is lifted, the seat cushion always has the action that the rear end is lifted and the front end is inclined forwards, and at the moment, the seat unlocking handle towel bar is lifted to synchronously unlock the function that the seat slides forwards and backwards. If the seat cushion interferes with the towel bar at this time, the seat may lose the function of sliding back and forth in the easy entry mode and the seat cushion cannot be folded over to the designed position.
With reference to fig. 1 to 3, a towel bar 30 is fixed to a spindle 28 by a harness 41 and a spring 48, and the towel bar 30 is normally pulled up to unlock, as disclosed in FR2883521B1 (its national patent application CN1827421 a) for a forwardly moving vehicle seat having a base frame and a forwardly foldable seat back. When subjected to abuse forces, the towel bar 30 can move down to the floor because the wiring harness 41 is not lengthened. When the back-fold easy entry function (another mode of the seat easy entry function) of the seat 34 is activated, the towel bar 30 is pulled up, and the abuse-proof function cannot be realized because the wire harness 41 is tightened at this time.
A longitudinal adjuster for a vehicle seat, such as that disclosed in KR101416324B1 (the national patent application CN103079877 a), is based on the principle that a spring is provided in the unlocking lever and the rotary shaft to effect separation under abusive force. However, this patent does not work in conjunction with the easy entry function of the seat.
For example, CN206012373U discloses a parallel mop unlocking mechanism of an easy-entry seat, the towel bar has no abuse-proof function, but the towel bar can be kept stationary when the seat starting cushion is folded and the easy-entry function is achieved, in the implementation manner, when the easy-entry function of the seat is started, the rotation of the seat connecting rod drives the bracket on the framework to press down the rotating shaft in contact with the slide rail unlocking pin for unlocking, the rotating shaft structure in contact with the slide rail unlocking pin and the slide rail towel bar unlocking mechanism are two sets of independent unlocking structures, and an additional interface is provided for the framework to achieve the function.

As described with reference to fig. 8a to 8g, in the present embodiment, when assembling, the winding portion of the first torsion spring 510 is firstly sleeved into the first side end 101 of the towel bar 100, and one end of the unlocking driving portion 110 is welded to the first side end 101 of the towel bar 100 (as shown in fig. 8a to 8 c); then, the first slide rail unlocking pressing plate 400a and the second slide rail unlocking pressing plate 400b are respectively sleeved on the two side ends 101 and 102 of the towel bar 100, the two ends of the synchronous rod 300 are respectively welded with the first slide rail unlocking pressing plate 400a and the second slide rail unlocking pressing plate 400b, and one end 511 and the other end 512 of the first torsion spring 510 are correspondingly connected to the unlocking driving part 110 and the first slide rail unlocking pressing plate 400a (as shown in fig. 8d to 8 e); finally, the second torsion spring 520 is sleeved into the first side end 101 of the towel bar 100, the second end 522 of the second torsion spring 520 is correspondingly connected with the first slide rail unlocking pressing plate 400a, the first end 521 of the second torsion spring 520 is to be connected to the upper slide rail, and the first plastic sleeve 610 and the second plastic sleeve 620 are correspondingly sleeved to complete the assembly (see fig. 8f to 8 g).
The working principle of the embodiment is as follows:
as described in conjunction with fig. 9 to 11, when the towel bar 100 is not subjected to an external force, the second torsion spring 520 keeps the first rail unlocking pressing plate 400a in an original state, the first rail unlocking pressing plate 400a keeps the towel bar 100 in contact with the first rail unlocking pressing plate 400a through the first torsion spring 510 and the unlocking driving part 110 in the original state, and because the torsion spring force is an internal force of the unlocking driving part 110 to rotate the towel bar 100, the first unlocking end 1 of the unlocking driving part 110 does not apply an additional unlocking force to the second unlocking end 2 on the first rail unlocking pressing plate 400a, and simultaneously, due to the action of the second torsion spring 520, the second unlocking end 2 of the first rail unlocking pressing plate 400a does not press the unlocking pin 202a in the first side rail assembly 200a and the second unlocking end 2 of the second rail unlocking pressing plate 400b does not press the unlocking pin 202b in the second side rail assembly 200b through the synchronization rod 300, so that the upper rail 201a, the lower rail 201b and the lower rail 201aa in the first side rail assembly 200a and the second side rail assembly 200b do not press the unlocking pin 201 aa;
as described with reference to fig. 12 to 14, when the towel bar 100 needs to be unlocked, the unlocking implementing rod 103 far away from the first end side 101 and the second end side 102 is subjected to an external force and rotates in the first direction (the external force in this embodiment is upward, so the first rotation direction is a counterclockwise arrow rotation direction in fig. 12), so that the unlocking driving portion 110 located at the first end side 101 of the towel bar 100 is driven to rotate in the first direction against the resistance of the second torsion spring 520, so that the first unlocking end 1 on the unlocking driving portion 110 also rotates in the first direction and acts on the second unlocking end 2 of the first slide rail unlocking pressing plate 400a, and at the same time, the synchronization rod 300 drives the second slide rail unlocking pressing plate 400b to rotate in the first direction, so that the second unlocking end 2 of the first slide rail unlocking pressing plate 400a acts on the unlocking pin 202a of the first side slide rail assembly 200a, and the second unlocking end 2 of the second slide rail unlocking pressing plate 400b acts on the unlocking pin 202b of the second side slide rail assembly 400b, so that the upper slide rail 201a, the lower rail 201bb and the lower rail 201bb in the slide rail assembly are slid to implement unlocking. Since the unlocking driving part 110 and the slide rail unlocking pressing plate 400a are always kept in a contact state in the unlocking process, the state of the first torsion spring 510 is not changed in the unlocking process, and the whole unlocking process only needs to overcome the resistance of the second torsion spring 520 and the unlocking force of the slide rail unlocking pin;
as described in conjunction with fig. 15 to 17, when the unlocking implementation rod 103 of the towel bar 100 away from the first end side 101 and the second end side 102 is acted by a downward abusive force to rotate in the second direction (the abusive force in this embodiment is downward, so the second rotation direction is a clockwise arrow rotation direction in fig. 15), the unlocking driving part 110 located at the first end side 101 of the towel bar 100 is driven to rotate in the second direction against the resistance of the first torsion spring 510, so that the first unlocking end 1 on the unlocking driving part 110 rotates in the second direction, and at the same time, the first rail unlocking pressing plate 400a tends to rotate in the second direction under the action of the first torsion spring 510, but since the end of the first rail unlocking pressing plate 400a away from the second unlocking end directly contacts the upper rail 201a under the action of the second torsion spring 520, the upper rail 201a prevents the rail unlocking pressing plate 400a from rotating in the second direction, and finally the abusive force makes the towel bar 100 rotate in the second direction until the towel bar is attached to the floor, so as to realize the balance under the counter-acting force of the floor; after the downward abuse force disappears, the first torsion spring 510 drives the unlocking driving part 110 back to the original state.

The working principle of the embodiment is as follows:
as described in conjunction with fig. 23 to 24, when the towel bar 100 is not subjected to an external force, the first torsion spring 510 and the third torsion spring 530 keep the first rail unlocking intermediate pressing plate 700 and the second rail unlocking pressing plate 400b at the original design position, while the first rail unlocking intermediate pressing plate 700 keeps a preloaded contact state with the unlocking driving part 110 by the action of the second torsion spring 520, and as the unlocking driving part 110 is welded to the towel bar 100, the towel bar 100 keeps at the original design state, while the second rail unlocking pressing plate 400b is connected to the unlocking auxiliary pressing plate 400a 'by the synchronization rod 300, so that the unlocking auxiliary pressing plate 400a' keeps at the original design state; in an original design state, a gap exists between the unlocking driving part 110 and the unlocking auxiliary pressing plate 400a ' so that the first unlocking end 1 of the unlocking driving part 110 does not apply unlocking force to the third unlocking end 3 on the first slide rail unlocking middle pressing plate 700 and the fourth unlocking end 4 of the unlocking auxiliary pressing plate 400a ', and further the second unlocking end 2 on the unlocking auxiliary pressing plate 400a ' does not press the unlocking pin 202a in the first side slide rail assembly 200a and the second unlocking end 2 on the second slide rail unlocking pressing plate 400b does not press the unlocking pin 202b in the second side slide rail assembly 200b, so that the upper slide rails 210a and 210b and the lower slide rails 210aa and 210bb in the first side slide rail assembly 200a and the second side slide rail assembly 200b are not unlocked;
as described in conjunction with fig. 25 to fig. 26, when the towel bar 100 needs to be unlocked, the unlocking implementation rod 103 away from the first end side 101 and the second end side 102 is rotated in the first direction by an external force (the external force in this embodiment is upward, so the first rotation direction is a clockwise arrow rotation direction as shown in fig. 25), and the unlocking driving portion 110 located at the first end side 101 of the towel bar 100 is driven to rotate in the first direction against the resistance of the first torsion spring 510, so that the first unlocking end 1 on the unlocking driving portion 110 is also rotated in the first direction synchronously, and when the unlocking auxiliary pressing plate 400a ' is rotated in the first direction after contacting the unlocking auxiliary pressing plate 400a ', the second unlocking end 2 on the unlocking auxiliary pressing plate 400a ' acts on the unlocking pin 202a of the first side slide rail assembly 200 a; in the process that the unlocking auxiliary pressing plate 400a' rotates in the first direction, the synchronization rod 300 drives the second slide rail unlocking pressing plate 400b to rotate in the first direction, and when the second slide rail unlocking pressing plate 400b rotates in the first direction, the second unlocking end 2 on the second slide rail unlocking pressing plate 400b acts on the unlocking pin 202b of the second side slide rail assembly 200b, so that unlocking is realized between the upper slide rails 210a and 210b and the lower slide rails 210aa and 210bb in the first side slide rail assembly 200a and the second side slide rail assembly 200 b; in this process, since the unlocking driving part 110 is in contact with the slide rail unlocking intermediate pressing plate 700 under the action of the second torsion spring 520 in the original design state, the first slide rail unlocking intermediate pressing plate 700 rotates along with the unlocking driving part 110 in the process of rotating to the first direction;
as described in conjunction with fig. 27 to fig. 28, when the unlocking implementation rod 103 of the towel bar 100 away from the first end side 101 and the second end side 102 is acted by a downward abusive force to rotate in the second direction (the abusive force in this embodiment is downward, so the second rotation direction is a counterclockwise arrow rotation direction in fig. 27), the unlocking driving portion 110 located at the first end side 101 of the towel bar 100 is driven to rotate in the second direction against the resistance of the second torsion spring 520, so that the first unlocking end 1 on the unlocking driving portion 110 rotates in the second direction, and under the action of the second torsion spring 520, the first slide rail unlocking intermediate pressing plate 700 also tends to rotate in the second direction, but because the end of the first slide rail unlocking intermediate pressing plate 700 and the upper rail are in contact with the upper slide rail 210a under the action of the first torsion spring 510, the movement tendency is hindered, so that the first slide rail unlocking intermediate pressing plate 700 always remains motionless during this process, and because the unlocking auxiliary pressing plate 400a' always remains a gap is left between the first unlocking intermediate pressing plate 700 and the unlocking driving portion 110, so that the unlocking auxiliary pressing plate 400a force keeps constantly rotating in the direction of the floor until the floor is finally balanced, so that the floor board 100 is acted by the downward abusive force; after the downward abuse force disappears, the first torsion spring 510 and the second torsion spring 520 drive the unlocking driving part 110 to return to the original state; since the end of the first slide rail unlocking intermediate pressing plate 700 away from the third unlocking end 3 in this embodiment is pressed against the upper slide rail 210a of the first side slide rail assembly 200a, the first slide rail unlocking intermediate pressing plate 700 is limited to the upper slide rail 210a in this state and does not rotate in the second direction, i.e., is always kept in the original design state as long as the elastic limits of the first torsion spring 510 and the second torsion spring 520 are set within a reasonable range.
As described with reference to fig. 29 to 31, when the seat function with the easy entry function is activated, the seat frame 800 presses the second unlocking end 2 on the unlocking auxiliary pressing plate 400a ' and the second unlocking end 2 on the second slide rail unlocking pressing plate 400b (or presses only one of them, and the synchronous rotation of the unlocking auxiliary pressing plate 400a ' and the second slide rail unlocking pressing plate 400b is realized by the synchronization lever 300), so that the second unlocking end 2 on the unlocking auxiliary pressing plate 400a ' and the second unlocking end 2 on the second slide rail unlocking pressing plate 400b synchronously move in the first direction (the seat frame 800 in this embodiment is pressed down, so the first direction is the clockwise arrow rotation direction in fig. 29), the second unlocking end 2 of the unlocking auxiliary pressing plate 400a ' and the second unlocking end 2 of the second slide rail unlocking pressing plate 400b simultaneously act on the unlocking pin 202a of the first side slide rail assembly 200a and the unlocking pin 202b of the second side slide rail assembly 200b, so that the unlocking is realized between the upper slide rails 210a and 210b and the lower slide rails 210aa and 210bb of the first side slide rail assembly 200a and the second side slide rail assembly 200b, and as the second slide rail unlocking pressing plate 400b and the unlocking auxiliary pressing plate 400a ' keep gaps with the first slide rail unlocking middle pressing plate 700 at the original design state and have no equal-phase spring force interaction, the effect that the towel bar is not moved when the cushion turnover easy-entry function is started is achieved.
