A kind of handrail locking and release mechanism and handrail, seat-assembly and vehicle
Technical field
The utility model relates to automotive seat technical field, particularly a kind of handrail locking and release mechanismAnd handrail, seat-assembly and vehicle.
Background technology
At present, most of chairs in rear rows of vehicles middle position all can be provided with rotating handrail. Work as passengerNeed to support ancon has a rest or needs to place the article such as water tumbler or want to open amusement function and seatWhen chair correlation function (as heating, ventilation, massage etc.), passenger can rotating handrail to be set level,Then placing articles or support ancon on handrail; In the time that more passenger need to occupy back seat,Can rotating handrail so that its turn in the container cavity on back seat, to present at chairs in rear rows of vehiclesGo out larger space.
For rear row's handrail of some luxury car seats, function is compared with horn of plenty, and weight is also than general holding upHeavy-handed a lot, in the time that handrail is in the closed position, just needing to have lockable mechanism to be locked at back seatUpper, that goes out forward due to self relation with row's handrail after preventing in brake process may.
In the disclosed a kind of armrest assembly of Chinese patent Granted publication CN204020462U, vehicle rear row seatIn seat assembly and vehicle, its handrail locking and release mechanism adopt connecting rod, spring, chute and stop pinStructure, the defect that this patent exists is that connecting rod and chute design organization complexity, cost are high, installs simultaneouslyMore complicated.
In the vehicle of listing at present, locking and the release mechanism of the rear row's handrail in luxury car AudiA8Adopt steel wire, spring, screw, rotating disk (upper and lower two), rotating disk connecting rod and stop pin, its shortcoming is to turnDish (upper and lower two) project organization complexity, cost is high; Rotating disk connecting rod and rotating disk (upper and lower two) simultaneouslyMore complicated is installed, adds top rotary table (upper and lower two) highly higher, needed installing space is larger.The handrail body of the required installation site of stop pin designs also more complicated in addition, and its machining accuracy is difficult to protectCard.

Detailed description of the invention
Referring to accompanying drawing 1, locking and release mechanism that a kind of automobile seat arm providing in figure uses, bagDraw together handrail body 100 and pair of armrests mounting bracket 210,220, arrange in the bottom of handrail body 100Have a rotating shaft 110, the two ends of rotating shaft 110 are inserted into the shaft hole of pair of armrests mounting bracket 210,220211,, in 221 and spacing by jump ring 111,112, handrail body 100 just can be by rotating shaft like this110 are hinged on pair of armrests mounting bracket 210,220 and are positioned at pair of armrests mounting bracket 210,220Between, handrail body 100 around the pin joint of itself and pair of armrests mounting bracket 210,220 at open positionAnd revolution (referring to Fig. 5 and Fig. 6) between lock position.
On each handrail mounting bracket 210,220, dispose a locking hole 212,222, whole locking andRelease mechanism is arranged in handrail body 100, this locking and release mechanism handrail body 100 in lockWhile stopping state, handrail body 100 is locked on pair of armrests mounting bracket 210,220 and is positioned at automobile(not shown) in the handrail body container cavity of seat.
This locking and release mechanism comprise release lever assembly 310, a pair of release drag-line 320,330 andTo lock pin assembly 340,350.
Referring to Fig. 9, release lever assembly 310 comprises release lever mounting cup 311 and a release lever especially312, install and operation release lever 312 for convenient, in handrail body 100, be provided with a release handHandle operating cavity 120. When assembling, first release lever 312 is arranged on to release lever peace by rotating shaft 313In dress cover 311, release lever 312 just can be hinged in release lever mounting cup 311 like this, passes throughExternal force can be pulled release lever 312 and carry out release. After release lever 312 assembles, then by releaseHandle mounting cup 311 adopts four screws 314 to be fixed on the back side of handrail body 100 and by release handAt the bottom of the chamber of handle operating cavity 120, cover.
Drag-line cover 321,331 in a pair of release drag-line 320,330 is respectively by being arranged on handrail bodyClamp 131,132,133,134,135,136,137 on 100 back sides is fixed on handrail body 100On the back side, one end of the drag-line rope 322,332 of each release drag-line 320,330 (namely Fig. 1 to 4,Upper end shown in Fig. 7) be connected with release lever 312.
Referring to Fig. 7, be provided with in the bottom at handrail body 100 back sides a pair of interior locking spindle guide corbel back slab 140,150 and a pair of outer lock sleeve mounting bracket 160,170, interior locking spindle guide corbel back slab 140 and outer lock sleeve peaceBetween dress support 160, form one in order to the region C of lock pin assembly 340 to be installed, interior locking spindle guide corbel back slab150 and outer lock sleeve mounting bracket 170 between form one in order to the region D of lock pin assembly 350 to be installed.Outside each, on lock sleeve mounting bracket 160,170, dispose an outer lock sleeve guide hole 161,171,In each, on locking spindle guide corbel back slab 140,150, dispose an interior locking spindle guide and draw hole 141,151.
Each lock pin assembly 340,350 comprises back-moving spring 341,351, outer lock sleeve 342,352With interior locking shaft 343,353, outside the outer end of lock sleeve 342,352 dispose a spring rib 342a,352a. When assembling, first the inner of interior locking shaft 343,353 is assemblied in to outer lock sleeve 342,352Endoporus in and extended by the outer end of outer lock sleeve 342,352, then by back-moving spring 341,351 coverBe located on the outer peripheral face of outer lock sleeve 342,352 and make the outer end of back-moving spring 341,351 be against external lockOnly overlap 342,352 upper lock pin assembly 340,350 can being assembled of spring rib 342a, 352a.After lock pin assembly 340,350 assembles, then snap onto respectively in region C, D and make outer lock sleeve342, the inner of 352 is through the outer lock sleeve guide hole on corresponding outer lock sleeve mounting bracket 160,170161,171, the outer end of interior locking shaft 343,353 is through corresponding interior locking spindle guide corbel back slab 140,150On interior locking spindle guide draw hole 141,151, now the outer end of back-moving spring 341,351 is against outer lock sleeveOn mounting bracket 160,170. Finally by the drag-line rope of each release drag-line 320,330 322,332The other end (the namely lower end shown in Fig. 1 to 4, Fig. 7) and each lock pin assembly 340,350In outer lock sleeve 342,352 the inner connect.
Referring to Fig. 3 and Fig. 4, when release, to scratch moving release lever 312 with hand and overturn downwards, each release is drawnThe drag-line rope 322,332 of rope 320,330 pull with each lock pin assembly 340,350 in outer lockingWhen cover 342,352 moves inward, outer lock sleeve 342,352 drives corresponding interior locking shaft 343,353Also synchronously move inward, interior locking shaft 343,353 is exited on corresponding handrail mounting bracket 210,220Locking hole 212,222 and release, now back-moving spring 342,352 is compressed.
Referring to Fig. 1 and Fig. 2, when locking, hand unclamps release lever 312, each release drag-line 320,330Drag-line rope 322,332 lose pulling force, back-moving spring 342,352 drive outer lock sleeve 342,352 toOuter movement, outer lock sleeve 342,352 drives corresponding interior locking shaft 343,353 also synchronous outwards mobile,Make interior locking shaft 343,353 reinsert locking hole 212 on corresponding handrail mounting bracket 210,220,In 222 and by handrail body 100 lockings.
For can be under lockup state, interior locking shaft 343,353 reinserts smoothly corresponding handrail and installsIn locking hole 212,222 on frame 210,220, referring to Fig. 5 and Fig. 6, at each handrail mounting bracket210, on 220 inner surface, dispose the arc guide groove 213,223 of a closed at both ends, locking hole 212,222 are configured in the lower end closed place of arc guide groove 213,223; When outside interior locking shaft 343,353End exits after the locking hole 212,222 on corresponding handrail mounting bracket 210,220, handrail body 100In switching process, the outer end of interior locking shaft 343,353 is in 213, the 223 interior slips of arc guide groove.
