Description

TECHNICAL FIELD

For people with difficulty in movement, efficient and reliable auxiliary retraction function is an important prerequisite for independent use of equipment, so the optimization design of related structures has become the focus of the industry.

[0004] The existing welfare seat 10 is mostly retracted into the driving structure 101 by being tilted backward, so that the welfare seat 10 is locked with the driving structure 101. The existing auxiliary retraction structure of the welfare seat 10 mostly relies on manual pushing to complete the retraction by electric driving, that is, the welfare seat 10 is first tilted backward into the driving structure 101 by the user or the helper, and then the welfare seat 10 is sent into the car or the storage space by electric or manual driving after the mechanical locking of the welfare seat 10 and the driving structure 101 is completed. However, this structure has high requirements for operation accuracy. The elderly or the disabled often have difficulty in accurately completing the docking action of tilting the welfare seat 10 backward into the driving structure 101 due to weak limb control ability and insufficient strength, and need to adjust the position repeatedly, which not only increases the operation difficulty, but also may cause locking failure due to docking deviation, affecting the retraction efficiency. For the above-mentioned related technology, the inventors believe that there is a defect that the operation threshold is high and it is difficult to independently use the requirement of precise reverse docking action.

[0043] The working principle of an auxiliary retraction structure for a welfare seat device in the present application is as follows: in the driving assembly 2, the motor 25 is connected to the guide rail 23 through the sliding block 24, at this time the gear 21 is not engaged with the rack 22, the sliding plate 3 is stationary, the tension spring 42 of the starting assembly 4 is in a natural state, one end of the rotating rod 43 is located outside the mounting plate 1, and the other end is rotationally connected to the mounting plate 1 through the rotating shaft 41; when the welfare seat moves from the side to the mounting plate 1, the welfare seat first pushes the external end of the rotating rod 43 of the starting assembly 4 to make the rotating rod 43 rotate around the rotating shaft 41, the other end of the rotating rod 43 is connected to the sliding block 24, and the rotating rod 43 rotates to synchronously drive the sliding block 24 to slide along the guide rail 23, the sliding of the sliding block 24 directly drives the motor 25 to move, and finally the gear 21 at the working end of the motor 25 is engaged with the rack 22 to provide power for the subsequent driving of the sliding plate 3; after the gear 21 is engaged with the rack 22, the motor 25 is started and drives the gear 21 to rotate, the rack 22 drives the sliding plate 3 to slide towards the welfare seat, when the sliding plate 3 moves to the preset position in the direction of the welfare seat, one side of the welfare seat abuts against the swing rod 322 of the swing driving rod 32, the swing driving rod 32 drives the lifting rod 34 to slide along the sliding groove 31 through the lifting sliding block 33, the lifting rod 34 slides to the inclined surface at the bottom end of the guide column 52, the guide column 52 is pushed to slide upward along the guide sleeve 51 through the extrusion and guiding effect of the inclined surface, the bottom plate 61 fixed at the top end of the guide column 52 is synchronously moved upward, and the whole rotating assembly 6 is lifted, after the rotating assembly 6 is lifted, the rotating plate 63 is embedded in the rotating groove 64 at the bottom of the welfare seat to form a rotating fulcrum, thereby providing structural support for the subsequent rotation and retraction of the welfare seat, after the rotating plate 63 is matched with the rotating groove 64 at the bottom of the seat, the sliding plate 3 continues to move back, at this time the rotating auxiliary assembly 7 intervenes, when the sliding plate 3 moves back, the auxiliary rod 76 of the rotating auxiliary assembly 7 first abuts against the side of the welfare seat, with the continuous movement of the sliding plate 3, the seat is passively rotated around the rotating base 62 with the rotating plate 63 as the fulcrum, and gradually moves towards the inside of the mounting plate 1, during the rotation of the seat, if the instantaneous resistance is too large, the second spring 74 in the auxiliary sleeve 71 will be buffered through the sliding of the telescopic rod 73 to avoid the rotation jamming of the welfare seat, in the process that the rotating rod 43 is pushed to rotate by the welfare seat, the locking assembly 8 acts synchronously to ensure the continuous work of the driving assembly 2, when the rotating rod 43 rotates to the position of the wedge block 87, the edge thereof first contacts the inclined surface of the wedge block 87, the wedge block 87 is forced to slide downward along the locking sleeve 85 through the extrusion of the inclined surface, when the rotating rod 43 completely passes the inclined surface, the fourth spring 86 resets to push the wedge block 87 to pop up, the non-inclined side of the wedge block 87 blocks the rotating rod 43 to prevent it from being reset under the action of the tension spring 42, after the rotating rod 43 is locked by the wedge block 87, the sliding block 24 driven thereby is fixed in position, the engagement state of the motor 25 and the rack 22 remains stable, when the welfare seat moves outward, the auxiliary sleeve 71 is first pushed to rotate around the mounting plate 1,The auxiliary sleeve 71 rotates to drive the fixed rod 81 to rotate synchronously. The fixed rod 81 drives the unlocking slider 84 to slide along the linear sliding rail 83 through the connecting rod 82. The unlocking slider 84 moves to the unlocking groove 44 of the rotating rod 43. The wedge-shaped block 87 is matched with the blocking of the rotating rod 43 to be removed. The rotating rod 43 reversely rotates around the rotating shaft 41 under the reset elastic force of the tension spring 42, drives the sliding block 24 to reset, and then makes the gear 21 disengage with the rack 22. After the rotating rod 43 is reset, the welfare seat is rotated to the position, which makes the swing rod 322 rotate around the support frame 321. At this time, the swing driving rod 32 is below the welfare seat, which does not affect the rotation of the welfare seat and the sliding of the jacking slider 33. The jacking rod 34 drives the jacking slider 33 to reset under the push of the reset rod 9. The guide column 52 slides downward under the action of the first spring 55. The second spring 74 and the third spring 75 of the rotating auxiliary assembly 7 reset. The fourth spring 86 of the locking assembly 8 drives the wedge-shaped block 87 to reset. The whole auxiliary recovery structure returns to the initial trigger state.

[0044] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
