A kind of wabbler mechanism of seat

Technical field

The utility model relates to furniture part technical field, in particular to a kind of wabbler mechanism of seat.

Background technique

The usual structure of the wabbler mechanism of existing market seat is sufficiently complex, and components are various, and assembly is complicated, at high cost It is high；Meanwhile existing wabbler mechanism can only have swinging condition substantially, mode is single, can not be needed according to client to swinging condition It is braked to stop oscillating motion, in addition, different swing angles when how to wave to wabbler mechanism carry out braking positioning more It is a problem, it can be seen that, it is more next that the wabbler mechanism that existing structure is complicated, mode is single has increasingly been unable to satisfy user More experience requirements.

It simplifies in order to overcome the shortcomings of the prior art, the utility model provides a kind of structure, have and wave and brake Two kinds of functional modes and the wabbler mechanism that can carry out braking the seat of positioning according to different swing angles.

Utility model content

The utility model overcomes above-mentioned the deficiencies in the prior art, provide a kind of structure simplify, have wave and It brakes two kinds of functional modes and the wabbler mechanism of the seat of braking positioning can be carried out according to different swing angles.

The technical solution of the utility model is achieved in that

A kind of wabbler mechanism of seat, including fixed frame, be articulated and connected a rocking carrier above fixed frame；The fixed frame And by the way that four-bar mechanism is arranged to realize that rocking carrier does oscillating motion relative to fixed frame between waving；In fixed frame and wave An arrestment mechanism that oscillating motion is done to brake rocking carrier is connected between frame.

The wabbler mechanism of the utility model only needs rocking carrier, fixed frame and the four-bar mechanism formed with them, just It is able to achieve oscillating motion of the rocking carrier relative to fixed frame, structure is simplified, and very simple is assembled, at low cost；Meanwhile this is practical new The wabbler mechanism of type is additionally provided with an arrestment mechanism to brake rocking carrier oscillating motion, arrestment mechanism simultaneously with fixed frame and shake Rocker connection, by arrestment mechanism and fixed frame it is relatively fixed then realize it is relatively fixed between fixed frame and rocking carrier, Solve the problems, such as that wabbler mechanism only has the single-mode of swinging condition, cannot be switched to on-position in the prior art, it is full The foot demand of user, and structure is simple, it is at low cost.

Preferably, the fixed frame includes stationary base mount and is fixed at the stationary base mount left and right sides and left and right in pairs The first side plate being arranged, the rocking carrier include waving pedestal and being fixed to wave at left and right sides of pedestal and control to set in pairs The second side plate set, parallel to each other and the two is closed between plane where plane where first side plate and the second side plate, together The first side plate and the second side plate of side are articulated and connected with two rocking bars simultaneously, two ipsilateral rocking bars, the first side plate and the The four-bar mechanism for waving rocking carrier front-rear direction is formed between two side plates.

The four-bar mechanism of the utility model, which only needs to be articulated and connected two between the first side plate and the second side plate, to wave Bar just forms the double leval jib for waving rocking carrier front-rear direction between two ipsilateral rocking bars, the first side plate and the second side plate Mechanism, structure is simple, at low cost.

Preferably, described two first side plates are located between two the second side plates, the upper end of two rocking bars is with the The top of side plate is hinged, lower hinge of the lower end of two rocking bars with the second side plate, and rocking bar and the first side plate it Between hinge joint position be higher than hinge joint position between rocking bar and the second side plate.

First side plate is fixed on fixed frame, and the second side plate is fixed on rocking carrier, by the upper end of two rocking bars with The top of first side plate is hinged, lower hinge of the lower end of two rocking bars with the second side plate, as user in use, active force It is supported at the hinge joint of two rocking bar lower ends and the second side plate lower part, is conducive to the oscillating motion for effectively realizing rocking carrier.

Preferably, the arrestment mechanism include a banking pin, one end of banking pin sequentially pass through the second ipsilateral side plate, Brake block B is connected again after brake block A and the first side plate, arc track is equipped on the first side plate, and the end of banking pin passes through arc Shape track can simultaneously take exercises along the track of arc track, and banking pin only does the sliding motion on left and right directions on the second side plate And it is waved with the second waving for side plate；The other end of banking pin is articulated and connected rotating member, rotating member by own rotation come Adjust banking pin left and right directions on slide displacement with adjust the phase between brake block A, brake block B and the first side plate from or compress State, to switch the oscillating motion state and on-position of rocking carrier.

In swinging condition, banking pin waves simultaneously with rocking carrier, and does oscillating motion along the track of arc track, As long as changing banking pin displacement in the lateral direction, be adjustable phase between brake block A, brake block B and the first side plate from Or impaction state, to switch the oscillating motion state and on-position of rocking carrier；Specifically, working as banking pin left and right directions position When shifting, a kind of situation be between brake block A, brake block B and the first side plate in mutually from or relaxation state (there are certain gaps), Rocking carrier can do oscillating motion, another situation is that, when being in impaction state between brake block A, brake block B and the first side plate, shake Rocker is fixed relative to fixed frame, and can not do oscillating motion, realizes on-position；In addition, there are one act on being by brake block A It can prevent banking pin from skidding off the first side plate, the second side plate.Amplitude difference, curved track are rocked since user is sitting on bench Road can according to need and oblique, also, the length of arc track is greater than and rocks amplitude, can reduce when rocking stop in this way Bring discomfort, simultaneously because banking pin is oval column, the both ends of arc track are half slot, can preferably be matched It closes, avoids banking pin deformation etc..

Preferably, the brake block A and brake block B are located at the two sides of the first side plate arc track, brake block A's One side is fixed with rubber sheet gasket A, and the one side of brake block B is fixed with rubber sheet gasket B, plays rubber pad in the braking state Piece A and rubber sheet gasket B is compressed with the outer peripheral edge of arc track two sides respectively.

Brake block A and brake block B clamps the rubber sheet gasket A and rubber sheet gasket B being located between the two, rubber sheet gasket A and rubber Glue gasket B friction arcuate track realizes brake block A, brake block B, relatively fixed between the first side plate, to realize braking effect Fruit；Frictional force can be enhanced in rubber sheet gasket A and rubber sheet gasket B, improves braking effect, while effectivelying prevent abnormal sound.
