Automotive seat can be adjusted for comfort, the angle of backrest now, can be made by the adjusting of angle With the demand of different occupants, Patent No. 201720516310.8, entitled " low-speed electronic vehicle seat chair back closing-folding mechanism " Utility model patent discloses a kind of low-speed electronic vehicle seat chair back closing-folding mechanism, and the applicable object of the patent is mainly low speed The backrest of electric vehicle, the concrete structure of this low-speed electronic vehicle seat chair back are shown in the attached drawing 1 of the patent, wherein holder and lean on It is connected by closing-folding mechanism between spine frame, but the closing-folding mechanism is exposed outside, very unsightly, and is received during folding Easily clip foreign matter at mechanism is rolled over, causes folding unsmooth or even fails.

Utility model content

In order to solve the above technical problems, applicant is in the mistake subsequently assembled to the above patent (201720516310.8) A kind of Cheng Zhong, it is proposed that covering at the automobile chair frame rotation of adaptability.

Technical solution is as follows：Covering at a kind of automobile chair frame rotation, key are：Including upper block piece under The lower part of block piece, the upper block piece is connect with the top of the lower block piece by connection structure and forms both ends open Half-surrounded, the lower block piece have elasticity.The covering is mounted on backrest using above-mentioned technical proposal, and from Rear surrounds folding structure, and during backrest rotates, lower block piece may contradict on holder, but due under Block piece is using softer and have both the material of certain elasticity and be made, such as rubber, lower block piece deform upon after being extruded, from Adjustment without influencing backrest, and lower block piece can automatically reply original state after this extruding revocation.

As preferred：

Above-mentioned upper block piece include two vertical faces settings on block side plate, block on two and be connected between side plate On block mainboard；

The lower block piece includes blocking side plate under two vertical face settings, and blocking side plate under two is located at two It is a it is described on block the underface of side plate, it is described on block to be provided with down immediately below mainboard and block mainboard, block mainboard under this Two sides respectively with two it is described under block side plate and connect；

The connection structure includes mutually matched connection tenon and docking fourth of the twelve Earthly Branches slot, it is described on block and set on the outer wall of mainboard Have the connection tenon, blocked under described mainboard inner wall be equipped with docking fourth of the twelve Earthly Branches slot, it is described on block mainboard outer wall and Under block the inner wall of mainboard and be fixedly connected, the connection tenon is plugged in docking fourth of the twelve Earthly Branches slot.

Upper connection between block piece and lower block piece fastens, is firm using the above structure.

Above-mentioned connection structure further includes mutually matched connection raised line and docking recess, two it is described on block the outer of side plate Its width direction of wall upper edge is respectively equipped with the docking recess, two it is described under block the inner wall upper edge of side plate its width direction point Not She You the connection raised line, it is described on block the outer wall of side plate with it is corresponding under block the inner wall of side plate and be fixedly connected, it is described Connection raised line is clamped in corresponding docking recess.It can further be reinforced between upper block piece and lower block piece using this scheme Degree of being completely embedded.

Mainboard is blocked under above-mentioned allows bit architecture, the deformation that bit architecture is allowed to include relief hole equipped with deformation, the resigning The length direction for blocking mainboard below hole under described is equipped with to step down and stitches, and the upper end for stepping down seam is connected to the relief hole, The lower end for stepping down seam extend to it is described under block the bottom of mainboard.Using this structure, block piece is extruded and deforms upon instantly Afterwards, deformation position can allow at bit architecture to deformation and expand, and influence closing-folding mechanism to be expanded to closing-folding mechanism side Operation.

The width of above-mentioned resigning seam is from the upper end toward lower end in increase tendency.In extruding becomes, under block mainboard and more lean on The deformation that generation is extruded at the position of nearly lower section is bigger, therefore needs the broader resigning seam of matching design.

Mainboard is blocked under above-mentioned and allows bit architecture equipped with two sets of deformation, and two sets of deformation allow the institute between bit architecture It states down to block mainboard lower part and turn down outwardly and forms shirt rim shape resigning portion.It can court and receipts after mainboard is extruded using being blocked under this structure The opposite side deformation of mechanism is rolled over, to not interfere with the operation of closing-folding mechanism.

It is blocked on above-mentioned and blocks the reinforced muscle reinforcement by connection of side plate difference on mainboard and its both sides.

Between above-mentioned upper block piece and lower block piece anti-overlap groove is circumferentially with along it.

The inner wall of above-mentioned upper block piece is equipped with mounting post, and mounting hole is offered in the mounting post.

Advantageous effect：Using the utility model has the beneficial effects that upper block piece and lower block piece respectively after folding structure Side is surrounded, and not only makes monnolithic case more attractive, while during adjusting backrest, lower block piece touches holder After elastic deformation occurs, to the adjustment of backrest concede enough spaces, the lower block piece deformed after adjusting the angle again Deformation can restore.
