Detailed Description

As shown in fig. 1 and 2, the suspension shock-absorbing device of the electric wheelchair comprises a support 1, a shock absorber assembly 2 and a side baffle 3, as shown in fig. 6, the support 1 comprises a

back plate

101, 2 mounting arms 102 are vertically bent from the bottom of the back plate 101, second isolation pipes 103 are welded at the mounting positions of the ends of the mounting arms 102 and the side baffle 3, as shown in fig. 5, the back plate 101 of the support 1 is fixedly connected to a driving wheel motor 19 through second screws 17 and second gaskets 18, a rotating shaft 4 passes through the second isolation pipes 103 and is matched with a disc-shaped gasket 7, a flat round head screw 12 and a hexagonal thin nut 8, the mounting arms 102 and the side baffle 3 are mounted on a chassis 14 of the electric wheelchair, as shown in fig. 4, the top of the side baffle 3 is fixed on the chassis 14 through first screws 15 and first gaskets 16, as shown in fig. 7, the shock absorber assembly 2 is structured as shown in fig. 7, the shock absorber assembly 2 is mounted between the 2 mounting arms 102, isolation tube 6 is installed to shock absorber subassembly 2 bottom, first bolt 9 passes isolation tube 6, fix shock absorber subassembly 2 on installation arm 102 with belleville washer 10 and thin nut 11 cooperation, 5 is installed at shock absorber subassembly 2 top, 5 side openings of fixed block have mounting

hole

501, 5 side openings of fixed block have with the protruding assorted spout 502 of side support 13, as shown in fig. 3, fixed block 5 utilizes second bolt 20 to pass through mounting hole 501, with flat button head screw 15, gasket 16 cooperation is installed on the side support 13 of electronic wheelchair.

During the use, when electronic wheelchair traveles on the ground of jolting, drive wheel motor 19 is run out from top to bottom, and this vibration transmits support 1 to drive support 1 through the spring in the rotation axis 4 rotation about tensile or compression shock absorber subassembly 2, absorb the impact of automobile body, restrain the vehicle and beat, improved the ground connection nature of tire to ground, guaranteed the security of wheelchair, improve the travelling comfort of user, the side shield 3 carries out the side swing spacing to shock absorber support 1 simultaneously, can ensure damper security.
