Description

Technical Field

[0001] The utility model relates to a shock-absorbing suspension structure, in particular to a shock-absorbing suspension structure of a mobility scooter for the elderly. Background Art

[0002] Most existing mobility scooters use a single cantilever structure in their front wheel suspension systems. However, due to the small size of mobility scooters, the cantilever's strength is limited, resulting in poor shock absorption and vibration resistance. When traveling on uneven and potholed roads, the front wheel can easily tilt relative to the ground, turning inward or outward. This not only increases abnormal wheel wear but also easily causes the cantilever to bend, increasing maintenance costs and even rendering the vehicle's front wheel suspension system useless. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model proposes a shock-absorbing suspension structure for elderly scooters, which is easy to install and disassemble. By adding an independent spiral shock-absorbing spring and an anti-hard collision installation structure, it facilitates the shock absorption and buffering of the vehicle's front suspension and increases driving comfort.

[0004] The cam is secured to the underside of the vehicle frame by a spring, and the cam is secured to the underside of the vehicle frame by a spring.

[0005] In the above technical solution, during actual installation, it is only necessary to sleeve the coil shock-absorbing spring onto the screw column of the shock-absorbing support frame, then align the screw column with the central screw hole on the shock-absorbing docking support plate, and then tighten it with the central fixing screw. The rear end of the shock-absorbing support frame can be fixed to the frame through the side fixing bolts. The installation is very convenient. By adding an independent coil shock-absorbing spring and an anti-hard collision installation structure on the basis of the original balance bar suspension structure, the overall structure is simple, low-cost, and easy to install, which is convenient for the vehicle's front suspension shock absorption and buffering, and increases driving comfort.

[0006] Preferably, shock-absorbing rubber pads are installed at the bottom and top of the spiral shock-absorbing spring to enhance protection of the spiral shock-absorbing spring.

[0007] Preferably, a shock-absorbing gasket is installed between the central fixing screw and the shock-absorbing docking support plate to reduce the collision between the central fixing screw and the shock-absorbing docking support plate and improve the service life of the central fixing screw.

[0008] Preferably, upwardly protruding limiting protrusions are provided on the left and right sides of the central screw hole on the shock-absorbing docking support plate to enhance the limiting of the central fixing screw.

[0009] Preferably, the folded edge is passed through the frame by a side fixing bolt and then locked by a locking nut to facilitate the docking and disassembly of the folded edge and the frame.

[0010] The beneficial effects of the shock-absorbing suspension structure of the elderly scooter provided by the utility model are as follows: the shock-absorbing suspension structure of the elderly scooter is reasonably designed and easy to install and disassemble. During actual installation, it is only necessary to sleeve the spiral shock-absorbing spring on the screw column of the shock-absorbing support frame, and then align the screw column with the center screw hole of the shock-absorbing docking support plate, and then tighten it with the center fixing screw. The rear end of the shock-absorbing support frame is fixed to the frame through the side fixing bolts. The installation is very convenient. By adding an independent spiral shock-absorbing spring and an anti-hard collision installation structure on the basis of the original balance bar suspension structure, the overall structure is simple, the cost is low, and it is easy to install, which is convenient for the front suspension shock absorption and buffering of the vehicle and increases driving comfort.
