Description

Two sections of chair back locks of vehicle

Technical field

This utility model belongs to technical field of automobile parts and in particular to a kind of two sections of chair back of vehicle are locked.

Background technology

Traditional back of seat for vehicle is by the only single unlatching of lock and latch functions.If running into some extreme cases, such as road Jolting in face, when people's spirit is tired, stops it is impossible to backrest is adjusted out a more comfortable position backrest during long-time sitting Breath.

Content of the invention

Technical problem to be solved in the utility model is to provide one kind to have two gear latch functions and drive mechanism Row increase effect, firm two sections of chair back locks of vehicle.

This utility model is realized in：

Two sections of chair back locks of vehicle, including housing and lock, are provided with buckle and unlocking relay in housing；Described buckle tool There are two grades of lock grooves, corresponding described two grades of lock grooves are configured with double-hasp；Described housing includes upper shell and lower house；Described button Plate and described unlocking relay all pivot using one first and are connected between upper shell and lower house；On described first pivot It is wound with one first torsion spring, described first torsion spring applies the power towards sealed direction to described unlocking relay；Described upper shell Also set up one second pivot and lower house between, described second pivot is wound with one second torsion spring, described second torsion spring is to institute State buckle and apply the power towards sealed direction.

Further, adopt rivet interlacement between described upper shell and lower house, described rivet is provided with deadener layer.

Further, it is provided with buffering relay in described housing, buckle into power for buffer described lock.

The utility model has the advantage of：Buckle of the present utility model is applied to promote buckle direction to buckle by the second knob spring The power in sealed direction, and effectively lock paid by lock, makes to latch in pair state firm.The lock groove of buckle, lock paid by corresponding lock Locking bar in front and back, makes seat have two-phase lock and stops function, can adjust seat back angle, and structure is simple, firmly.

Brief description

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 is that status architecture schematic diagram paid by one grade of lock of this utility model.

Fig. 2 is that status architecture schematic diagram paid by two grades of locks of this utility model.

Specific embodiment

As depicted in figs. 1 and 2, two sections of chair back locks of vehicle, including housing and lock 1, are provided with buckle 2 and unlock in housing Relay 3；Described buckle 2 has two grades of lock grooves, and corresponding described two grades of lock grooves are configured with double-hasp 1；Described housing includes Upper shell 7 and lower house 8；Described buckle 2 and described unlocking relay 3 are all rotationally connected with upper shell using one first pivot 9 And lower house between；One first torsion spring 4 is wound with described first pivot 9, described first torsion spring 4 is to described unlocking relay 3 Apply the power towards sealed direction；One second pivot 11, described second pivot 11 is also set up between described upper shell and lower house On be wound with one second torsion spring 5, described second torsion spring 5 applies the power towards sealed direction to described buckle 2.Described upper shell and Connected using rivet 6 between lower house, described rivet 6 is provided with deadener layer.

Pay operation principle to each lock separately below to illustrate：

One section of lock is paid：

See Fig. 1, in lock body assembling and seat, lock body, with turnover seat to stand up position, latches 1 shock buckle 2, buckle 2 flick；Latch 1 start to stop to unlocking relay 3, buckle 2 is subject to the first torsion spring 4 active force, before buckle 2 resilience buckles into lock 1 Bar.

Two-stage nitration lock is paid：

See Fig. 2, unlocking relay 3 passes through the boss of buckle 2, drive buckle 2 toward sealed rightabout start；Before lock 1 Bar unlocks, turnover seat, drives lock body to buckle into locking bar 1 rear bar, buckle 2 is buckled into after lock 1 by the first torsion spring 4 active force resilience Bar.Unlocking relay 3 is acted on by the second torsion spring 5 and resetting toward sealed direction.

Unblock：

See Fig. 2, unlocking relay 3 passes through the boss of buckle 2, drive buckle 2 toward sealed rightabout start；Seat turns over Arrive, lock body departs from lock 1.

This product is arranged on seat heel row, and two-phase lock enables two grades of regulations, and 3 unlocking relay 3 start is in buckle 2 Boss encapsulated towards sealed rightabout start；It is covered with the second pivot 11, the second pivot 11 is wound with the second torsion spring 4, institute on described State the second torsion spring 4 and put on the encapsulated power towards sealed direction of buckle 2 boss.It is provided with buffering relay 10 in housing, buffer lock 1 Buckle into power；Upper lid 7 and lower cover 8 connect through rivet 6 and connect, and rivet 6 carry deadener layer, when buckle 2 resets, directly Deadener layer on contact rivet 6, plays the effect of noise reduction, when state paid by buckle 2 lock, buckle 2 stress deformation, and rivet 6 Play a supporting role above buckle 2, improve lock body intensity.

This product buckle is applied to promote buckle 2 towards the power in sealed direction to buckle 2 by the torsion spring 5 of the second pivot 11, and Effectively lock paid by lock, makes to latch in pair state firm.The lock groove of buckle 2, locking bar before and after lock paid by corresponding lock, makes vehicle Seat has two-phase lock and stops function, can adjust seat back angle, and structure is simple, firmly.

Above-described embodiment and schema non-limiting product form of the present utility model and style, any art Suitable change or modification that those of ordinary skill is done to it, all should be regarded as without departing from patent category of the present utility model.
