Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment is arranged on the desk on automotive seat, comprises Connection Block 1 and table body, and described table body comprises outer desktop 2, interior desktop 3 and straight guide 4;
Described interior desktop 3 is fixedly installed on straight guide 4, and described outer desktop 2 is enclosed within outside interior desktop 3, and described outer desktop 2 can to slip away interior desktop connect with interior desktop 3 and form desktop body along straight guide 4;
Described straight guide 4 and Connection Block 1 hinged;
Described desk also comprises the lockable mechanism stoping straight guide 4 to rotate around jointed shaft.
The Connection Block 1 of this desk is fixedly attached in the backrest back side of front-row seats of vehicle, outer desktop 2 is drawn to the state connected with interior desktop 3 along straight guide 4, move a body again to horizontality, the passenger on back seat just can use computer on table body, can bring great convenience to passenger.
As the improvement to the present embodiment, described outer desktop 2 is provided with the guidepost 5 of band dovetail furrow 5a, described guidepost 5 is also provided with dovetail furrow bottom through rectangle limit sliding chutes 5b, described straight guide 4 is provided with the dovetail form gib block 4a with dovetail furrow 5a bearing fit, described dovetail form gib block 4a is provided be arranged in rectangle limit sliding chutes 5b and with the banking pin 6 of its bearing fit.Under the directional tagging of dovetail furrow 5a and dovetail form gib block 4a, outer desktop 2 reciprocally smooth sliding, and because the miles of relative movement of banking pin 6 is subject to the restriction at the forward and backward two ends of rectangle limit sliding chutes 5b in sliding process, thus the sliding distance of outer desktop 2 can be limited.Certainly in different embodiments, dovetail furrow 5a and dovetail form gib block 4a also can adopt other structure to replace, as available T slot or T-shaped gib block.
As the improvement to the present embodiment, described lockable mechanism comprise be provided with straight runner guide holder 7, with the push rod 8 of straight runner single degree of freedom bearing fit on guide holder 7, with lock pin 9 connecting plate 10 and be provided with the push pedal 12 of oblique chute 11, described straight guide 4 is provided with the direction recess that depth direction is axially parallel with lock pin 9, described connecting plate 10 is provided with the protruding 10a with direction recess bearing fit, described Connection Block 1 is provided with the pin-and-hole 13 coordinated with the grafting of lock pin 9 detachable;
Described push pedal 12 is fixedly installed on outer desktop 2, and described guide holder 7 is relative with straight guide 4 to be fixedly installed;
One end of described push rod 8 withstands on connecting plate 10, the other end of push rod 8 is fixedly connected with trundle 14, and described trundle 14 is arranged in the oblique chute 11 of push pedal and can reciprocatingly slides along oblique chute 11;
Described connecting plate 10 is also provided with one end withstands on connecting plate 10, the other end withstands on retracing spring 15 on straight guide 4.
When desk will be used, outer desktop 2 first need be pulled out.When pulling outer desktop 2 to slide along straight guide 4, push pedal 12 is moved together with outer desktop 2, push pedal 12 is moved the trundle 14 that just can promote in oblique chute 11 and is slided along oblique chute 11, trundle 14 moves and drives push rod 8 to move along the straight runner on guide holder 7 simultaneously, the cross-sectional plane of described straight runner can be rectangle, T-shaped or dovetail form etc., push rod 8 moves and just can promote connecting plate 10 and move along the depth direction of direction recess on straight guide 4, thus make lock pin 9 exit pin-and-hole 13, at this moment just rotatable table body turns to horizontality around jointed shaft.
Certainly in different embodiments, described lockable mechanism also can be other structure, as a pin hole can be established on Connection Block, table body arranges a latch be threaded with it, described latch is inserted in pin hole and forms lockable mechanism, when needs rotary table body, rotating latch can extract latch from pin hole; This Structural lock locking mechanism structure is simple, but its operation convenience is not as the lockable mechanism disclosed in the present embodiment.
As the improvement to the present embodiment, the jointed shaft 16 of described Connection Block 1 and straight guide 4 is fixed on straight guide 4, on described jointed shaft 16, cover has the plate 17 with its normal-running fit, and described plate 17 and the detachable socket connection of Connection Block 1 and described plate 17 are fixed on Connection Block 1 by screw 18.This structure makes to pull down screw 18 and just table body can be pulled down from Connection Block 1, and ease of assembly, is conducive to enhancing productivity.
A kind of front-row seats of vehicle being provided with any desk aforementioned of the present embodiment, comprises seat body, and the Connection Block 1 of described desk is connected in the backrest back side of seat body.Passenger on this construction car front-row seats makes to sit in the back row can use desk placing articles, particularly computer that it is arranged, can be convenient for people to be convenient to use computer in riding process.
As the improvement to the present embodiment, described Connection Block 1 is fixedly connected in the backrest back side of seat body by screw, and this structure makes the dismounting of desk all convenient and swift, is also convenient to maintenance and the replacing of desk.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
