Description

A kind of automotive seat ground lock construction

Technical field

The utility model is related to a kind of arta vehicle seat unit；More particularly to a kind of automotive seat ground lock construction.

Background technology

The folding of automotive seat, can facilitate user according to actual conditions, improve the utilization rate of interior space.

The folding of seat is, it is necessary to set the cooperation of the ground lock construction between body platform and chair framework.Ground lock construction includes The ground lock of the rear end of chair framework bottom, and the lock pin being fixed on body platform are fixedly connected on, between ground lock and lock pin Hook and coordinate.Hook and have certain gap between the lock pin coordinated and ground lock, when driving, when the vibration of vehicle body is transferred to When ground is locked with lock pin, the noise of shock occurs between.The noise of presence can influence relaxing for passenger to a certain extent Adaptive.

The content of the invention

The purpose of this utility model is to solve, and the problem of noise occur between lock pin is locked at present.

In order to solve the above problems, the utility model proposes a kind of automotive seat ground lock construction, including it is fixedly connected present The ground lock of the rear end of chair skeleton bottom and the lock pin that is fixed on body platform, lock describedly the latch hook of interior rotation with it is described Lock pin, which is hooked, to be coordinated, in addition to the cushion pad that squeezed state is between lock pin is locked positioned at ground, and the cushion pad is used to eliminate Fit clearance between latch hook and lock pin.

Further, lock describedly including the latch hook, rotating shaft, reset tension spring, extension pin and ground lock framework；Latch hook passes through rotating shaft It is rotatably connected on and locks describedly in framework；One end of the reset tension spring is connected on latch hook, and its other end with being arranged on is locked Extension pin connection in framework；In the presence of reset tension spring, latch hook is pulled to lock pin, and hooks cooperation therewith.

Further, the limiting gasket for the spacing latch hook is arranged with the rotating shaft.

Further, in addition to the locating part locked describedly in framework is fixed on, between the locating part and base framework It is formed with the groove for installing cushion pad.

Further, in addition to unblock drawstring and unblock drawstring dististyle, one end of the unblock drawstring dististyle and unblock drawstring Connection, its other end is rotated with the latch hook and is connected, and the mated condition of the latch hook and lock pin is controlled by unlocking drawstring.

Further, the latch hook includes the first latch hook and the second latch hook being fixedly connected, and is opened up on first latch hook There is the connecting hole being connected with the reset tension spring.

The beneficial effects of the utility model are：

1st, the cushion pad in squeezed state can be deformed by it, to weaken the vibration in vehicle travel process.And lead to The weakening to vibration is crossed to avoid the noise sent between latch hook and lock pin.

2nd, the utility model is simple in construction, easy for installation.

Brief description of the drawings

The utility model is described in further detail with reference to the accompanying drawings and detailed description：

Fig. 1 is integral installation schematic diagram of the present utility model；

Fig. 2 is the enlarged drawing at A in Fig. 1；

Fig. 3 locks 2 structural representation for ground；

Fig. 4 is Fig. 2 left view；

In figure：Chair framework 1；Ground lock 2；Framework 21 is locked on ground, and reset tension spring 22, latch hook 23 hangs pin 24, rotating shaft 26, unblock Drawstring 27, unblock drawstring dististyle 28, limiting gasket 29；Lock pin 3；Locating part 41, cushion pad 42.

Embodiment

Join Fig. 1, Fig. 2, the application utility model automotive seat ground lock construction, positioned at the bottom rear end of chair framework 1.This reality With new including the ground lock 2 being fixed on chair framework 1 and the lock pin 3 being fixed on body platform, the latch hook inside 2 is locked on ground Hook and coordinate between 23 and lock pin 3.

Referring to Fig. 2, Fig. 3, Fig. 4, above-mentioned ground lock 2 includes ground lock framework 21, reset tension spring 22, latch hook 23, rotating shaft 26, extension Pin 24.Overall ground lock framework 21 is in door frame shaped, and latch hook 23 locks the bottom of framework 21 by rotating shaft 26 with being rotatably connected on；Hang pin 24 Lock the top of framework 21 with being fixedly connected on, one end of reset tension spring 22, which is hooked, to be connected on extension pin 24, and its other end, which is hooked, to be connected It is connected on latch hook 23, under the pulling force of reset tension spring 22, latch hook 23 is rotated along rotating shaft 26 to direction of pull.For convenience to turning Latch hook 23 on axle 26 is positioned, and limiting gasket 29 is arranged with rotating shaft 26, under the axial limiting of limiting gasket 29, lock Hook 23 is located at the middle part of rotating shaft 26.The left and right sides for locking framework 21 on ground is respectively fixed with locating part 41, in locating part 41 and ground Form fluted between lock framework 21, cushion pad 42 is provided with groove.

Lock pin 3 is fixed on body platform, and its position is corresponding with the position of latch hook 23, is hooked in latch hook 23 with lock pin 3 Under mated condition, the hook of latch hook 23 and lock pin 3 coordinates, and hook state is carried out by the reset tension spring 22 in extended state Keep.

When latch hook 23 and lock pin 3 are in and hooked under mated condition, cushion pad 42 be located at ground lock framework 21 and lock pin 3 it Between, and in squeezed state.Under the position-limiting action of the cushion pad 42 under squeezed state, between latch hook 23 and lock pin 3 Fit clearance is eliminated.Cushion pad 42 under squeezed state can be deformed by it, be vibrated to weaken in vehicle travel process. By reducing the relative motion between latch hook 23 and lock pin 3 to the elimination of vibration, while it also avoid because relative motion band The noise problem come.

The hook state between latch hook 23 and lock pin 3 is artificially released for convenience, and the utility model also includes unblock and drawn Band dististyle 28 and unblock drawstring 27.Unblock drawstring dististyle 28 is rotatably connected on latch hook 23, and unblock drawstring 27 is connected to unblock and drawn On band dististyle 28.

In such scheme, latch hook 23 can be stationarily connected to the first latch hook and the second latch hook together.In the first lock The edge of hook first latch hook overlapping with the second latch hook is protruding with hook portion, is offered in hook portion and the hook of reset tension spring 22 Hang the connecting hole of connection.Overlapping the first latch hook and the second latch hook can guarantee that the bulk strength of latch hook, and the hook portion protruded exists The thickness overall less than latch hook 23, can so facilitate the hook of reset tension spring 22 on integral thickness.
