Description
Technical field
The utility model relates to the seat part technical field, particularly a kind of seat floor latch device.
Background technology
The seat that turns over function in the market before the band that manned vehicle uses mainly fastens the realization locking by the fixedly steel wire of installing on the seat on floor latch device and the vehicle body.Referring to Fig. 3 to Fig. 6, this seat floor latch device comprises parts compositions such as release lever 20, latch hook 40, latch hook mounting bracket 50, retracing spring 90, synchronizing bar 30, latch hook mounting bracket 50 is two, be fixedly mounted on the both sides of seat 10 respectively, latch hook 40 also is two, be hinged on respectively on the latch hook mounting bracket 50 and by synchronizing bar 30 and link, be provided with a retracing spring 90 between 50 between each latch hook 40 and each latch hook are installed, release lever 20 is installed on the latch hook 40.
When needs tip-up set 10, referring to Fig. 1 and Fig. 3, pull release lever 20 with hand, by the latch hook 40 (normally 2) installed on the drive floor latch devices such as synchronizing bar 30 around hinge-point 60 left-hand revolutions between itself and the latch hook mounting bracket 50, fixedly steel wire 70 backs that latch hook 40 is crossed on the vehicle body arrive open position realization release, seat 10 can overturn forward around preceding hinge-point 80, and makes the space at seat 10 rears bigger with in order to loaded with articles or for people's turnover etc.In the time of need taking seat, referring to Fig. 2 and Fig. 4 to Fig. 6, seat 10 is turned over around preceding hinge-point 80, the circular arc of latch hook 40 bottoms at first contacts with fixedly steel wire 70 on the vehicle body, forces latch hook 40 around hinge-point 60 left-hand revolutions between itself and the latch hook mounting bracket 50, cross transformation point after, under the effect of retracing spring 90, latch hook 40 hooks the fixedly steel wire 70 on the vehicle body and maintains the lock status under the effect of retracing spring 90 always, and at this moment seat 10 is locked, and waits for release next time.
Existing floor latch device in use has the following disadvantages:
1, be proof strength, usually latch hook 40 adopts thickness to obtain greater than the Used for Sheet Stamping of 5mm, to having relatively high expectations of equipment input, fine blanking part at first on cost than general towards the part height.
2, increase latch hook 40 intensity as need, usually to increase latch hook 40 width, prior art just simply is superimposed together the polylith plate, required intensity is big more, the material of required stack is many more, from the angle of cost is non-remunerative, because the material that do not needed the also passive increase in the position strengthened.
For this reason, Chinese patent Granted publication number discloses a kind of minicar back seat snap close for CN201484233, referring to Fig. 7 and shown in Figure 8, this minicar back seat snap close is made of permanent seat 1, button 2, latch hook 3, installation component and unlatching handle 8, wherein permanent seat 1 is made up of two vertical plate 1a that are symmetrical set and back connecting panel 1b, " n " type draw-in groove 1a ' is all offered in bottom at two vertical plate 1a, this draw-in groove 1a ' can cooperate with button 2 clampings, button 2 is flat " U " shape structure that crouches, and is weldingly fixed on the body platform.Link to each other by back connecting panel 1b between the back side edge at two vertical plate 1a tops, the top of this back connecting panel 1b bends forward, forms upper overturning 1c, and upper overturning 1c welds mutually with the bottom of back seat rear end.Between two vertical plate 1a of permanent seat, be provided with latch hook 3, this latch hook 3 is made of two side plate 3a that are symmetrical set and backboard 3b, the top of biside plate 3a is hinged by installation component and permanent seat vertical plate 1a, offer hook groove 3a ' in the bottom of biside plate 3a, side plate 3a can cooperate with button 2 clampings by hook groove 3a '.It can also be seen that from Fig. 7 and Fig. 8, installation component is made of swivel pin 4, locking spring 5, lining 6 and jump ring 7, the biside plate 3a of latch hook 3 is installed on the permanent seat vertical plate 1a by the swivel pin 4 that is with lining 6, swivel pin 4 is by jump ring 7 axial limitings, locking spring 5 is sleeved on the swivel pin 4, and between the biside plate 3a of latch hook, the lower surface of the open end of locking spring 5 and permanent seat upper overturning 1c connects, and the closing end of locking spring 5 overlaps mutually with the top of latch hook backboard 3b trailing flank.Trailing flank at backboard 3b is welded with horizontally disposed unlatching handle 8.
The principle of work of this minicar back seat snap close is: in the time of need overturning back seat forward, catch unlatching handle 8 with hand, and will open handle 8 and upwards carry, latch hook 3, permanent seat 1 and back seat be upward movement under the drive of opening handle 8, back seat overturns forward around the hinge-point of its bottom front simultaneously, in the process of latch hook 3 upward movements, the hook groove 3a of latch hook 3 breaks away from button 2 gradually, the draw-in groove 1a of permanent seat 1 also breaks away from button 2 gradually, after back seat turns over 90 °, back seat is upset forward automatically under the effect of gravity, contacts with body platform at last.
Though its latch hook 3 adopts the U-shaped like structure in the above-mentioned patent, but its latch hook 3 still seems thin with the latch hook position of button 2, its load-carrying capacity is very limited, the locking spring 5 that still relies on the torsion spring structure that resets of above-mentioned patent latch hook 3 resets in addition, and adopts torsion spring will be unfavorable for dismantling maintenance after installation and the generation fault.
