AI Technical Summary
Technical Problem
The hinges of existing car seat tray tables lack damping, resulting in a loose feel and abnormal noise during use, and the exposed hinge mechanism affects the aesthetics.
Method used
It adopts a concealed folding damping hinge, including a bridging housing, Y-shaped damping leaf spring, cotter pin, plug, connecting plate, buffer pad and spindle. The damping force is generated through the friction pair. Combined with the self-limiting structure and U-shaped clearance, it achieves smooth operation and aesthetic concealment.
Benefits of technology
The noise has been eliminated, the feel of operation has been improved, and the stability and aesthetics of the small table when unfolding and folding have been ensured. The hidden hinge structure avoids interference.

Abstract
The utility model relates to the technical field of automobile interiors, in particular to a hidden type folding damping hinge and an automobile seat small table board with the hinge, which comprises a bridging shell, Y-shaped damping leaf springs, a cotter pin, a plug, a connecting plate, a cushion pad and a mandrel, two groups of Y-shaped damping leaf spring positioning grooves are arranged in the bridging shell, and the Y-shaped damping leaf springs are arranged in the Y-shaped damping leaf spring positioning grooves. At least two Y-shaped damping leaf springs are assembled in each set of Y-shaped damping leaf spring positioning grooves, the plugs are installed at the tail ends of the Y-shaped damping leaf spring positioning grooves, the connecting plates are rotationally arranged on the outer sides of the Y-shaped damping leaf spring positioning grooves, one ends of the buffering pads abut against the bridging shell, the other ends of the buffering pads abut against the connecting plates, and the other ends of the buffering pads abut against the connecting plates. The mandrel penetrates through the connecting plate and the bridging shell, and the mandrel and the Y-shaped damping leaf spring form a friction pair to generate damping force. According to the hinge, through the damping structure and the limiting mechanism, the stability of a table board is improved; and the overall attractiveness is improved through the hidden layout.
