[0002] A car's driving stability, comfort, safety, smoothness and off-road performance are all closely related to the suspension system in the chassis structure. Most cars now use independent suspension systems. According to their different structural forms, independent suspension systems are mainly divided into: McPherson independent suspension system, double wishbone independent suspension system, multi-link independent suspension system, drag independent suspension system, etc. The performance of McPherson independent suspension system in driving comfort is satisfactory.

[0003] At present, when the existing independent hanging type swing arm mechanism is used, it only uses a buffer to connect with the flexible part to reduce the shock of the bracket. The shock absorption effect is not very ideal and the applicability is poor. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides an independent suspension shock-absorbing bracket swing arm mechanism, which overcomes the shortcomings of the existing technology and aims to solve the problem that the existing simple sampling equipment is inconvenient to use when facing hard geology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an independently suspended shock-absorbing bracket swing arm mechanism, comprising a base, wherein the upper end of the base is symmetrically provided with two slide grooves, two sliders are symmetrically slidably connected in the slide grooves, two shock-absorbing springs are symmetrically connected on the inner groove walls of the slide grooves, the other ends of the shock-absorbing springs are connected to the corresponding sliders, two fixed plates are symmetrically arranged above the base, the upper ends of the sliders pass through the notches of the slide grooves and extend upward and are hinged to a transmission rod, the other end of the transmission rod is hinged to the corresponding fixed plate, the upper end of the base is connected to a horizontal plate, and two shock absorbers are symmetrically mounted on the upper ends of the horizontal plate, and the protruding ends of the shock absorbers are connected to the fixed plate. The upper end of the fixed plate is connected to a vertical plate, and the two vertical plates are connected to a first reciprocating screw rod that is rotated together, and a rotating part for driving the first reciprocating screw rod to rotate is installed on the vertical plate, and a movable block is threadedly connected to the rod wall of the first reciprocating screw rod, and the two vertical plates are connected to a mounting plate together, and a rotating gear is rotatably installed on the side wall of one side of the mounting plate, and the lower end of the movable block is connected to a rack, and the rotating gear is meshed with the rack, and the end of the rotating gear away from the mounting plate is connected to a longitudinal arm, and two connecting frames are symmetrically installed on the longitudinal arm, and a horizontal arm is commonly installed at the lower ends of the two connecting frames, and a cleaning component for cleaning dust on the base is installed on the base.

[0006] By adopting the above technical solution, during operation, the first reciprocating screw is rotated by the rotating member, and the rotation of the first reciprocating screw causes the movable block to perform a horizontal reciprocating motion through the action of the thread. The movement of the movable block drives the rack to move, and the movement of the rack drives the rotating gear to rotate. The rotation of the rotating gear drives the longitudinal arm to swing, and the swing of the longitudinal arm drives the connecting frame to move.
