Description

Technical Field

[0001] The utility model belongs to the technical field of shock-absorbing structures, and in particular relates to a novel nonlinear shock-absorbing structure. Background Art

[0002] Shock absorption, also known as building vibration reduction (structural energy dissipation and vibration reduction), is a shock absorber structure consisting of a piston rod inserted into a cylinder filled with oil. The piston has an orifice, allowing the oil in the two compartments separated by the piston to replenish each other. Damping is generated when the viscous oil passes through the orifice. The smaller the orifice, the greater the damping force, and the greater the oil viscosity, the greater the damping force. If the orifice size remains unchanged, when the shock absorber operates at high speeds, excessive damping will affect the absorption of shock.

The movable rod 83 is pressed to push the extrusion plate 86 to move, and at the same time, the limit ring 84 pushes the limit spring 85 to be compressed. At this time, the air inside the lubricating oil tank 81 is squeezed to pump the lubricating oil out from the upper oil pipe 82 and the lower oil pipe 87 respectively, ensuring the convenience of lubrication of the connecting shaft, improving the use effect of the equipment, and ensuring the shock absorption quality.

[0044] Specifically, the lubricating oil tank 81 and the movable frame 6 are an integrated structure, and an oil filling hole is provided on one side surface of the lubricating oil tank 81 .

[0045] By adopting the above technical solution, the stability of the installation of the lubricating oil tank 81 is ensured and the use intensity of the equipment is improved.

[0046] A unicycle comprising the nonlinear shock absorbing structure as described above, further comprising:

[0047] Frame, used to bear weight;

[0048] A battery compartment that powers the unicycle and synchronizes the frame's movement with the novel nonlinear shock-absorbing structure;

[0049] The movable frame 6 is mounted on the battery compartment, and the battery compartment is mounted on the vehicle frame.

[0050] By adopting the above technical solution, the battery compartment can be installed outside the frame, making it easier for users to perform daily maintenance on the battery compartment.

[0053] The working principle and use process of the utility model: When the utility model is in use, when an external force acts on the movable frame 6, the movable frame 6 is forced to move downward along the support component 5. At the same time, the first connecting frame 1 at one end of the third connecting frame 9 is forced to move closer to the mounting frame 4. At this time, the telescopic rod 3 contracts and the shock-absorbing spring 2 is compressed to buffer the movable frame 6. When the shock-absorbing spring 2 is reset, the movable frame 6 moves up again and releases the elastic potential energy of the shock-absorbing spring 2 through the friction force with the support component 5, thereby ensuring the shock-absorbing effect of the equipment.

[0054] During long-term use, the connecting shafts between the first connecting frame 1 and the third connecting frame 9 and the mounting frame 4 and the second connecting frame 7 need to be lubricated to improve their rotation effect. Press the movable rod 83 so that it pushes the extrusion plate 86 to move, and at the same time, the limit ring 84 pushes the limit spring 85 to be compressed. At this time, the air inside the lubricating oil tank 81 is squeezed and the lubricating oil is pumped out from the upper oil pipe 82 and the lower oil pipe 87 respectively, ensuring the convenience of lubrication of the connecting shaft, improving the use effect of the equipment, and ensuring the shock absorption quality.
