Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a bicycle shock attenuation power generation facility, including bumper shock absorber piston bush 1, the inside movable sleeve of bumper shock absorber piston bush 1 is equipped with bumper shock absorber piston 2, the outer wall integrated into one piece of bumper shock absorber piston 2 has annular plate 21, the upper end of annular plate 21 and the welding of the inner wall top of bumper shock absorber piston bush 1, the inside top intercommunication through hydraulic oil pipeline 7 and static pivot piston bush 6 in the top of bumper shock absorber piston bush 1, the inside activity of static pivot piston bush 6 is pegged graft and is had movable armature piston 8, the welding has movable armature return spring 9 between the lower extreme of movable armature piston 8 and the bottom of static pivot piston bush 6.
Specifically, a first vertical hole 10 and a second vertical hole 11 are sequentially formed in the moving armature piston 8 in a penetrating manner from left to right, a power generation check valve 12 and a damping check valve 13 are sequentially arranged in the first vertical hole 10 and the second vertical hole 11, hydraulic oil flows to a cavity of the damper piston sleeve 1 through a hydraulic oil pipeline 7, the moving armature piston 8 is reset under the action of a moving armature return spring 9, and magnetic lines of force are cut again to generate power; when the armature piston 8 is reset, the damper piston 2 continues to move, and the aforementioned hydraulic oil flowing through the power generation check valve 12 now flows in reverse through the damper check valve 13 until the damper piston 2 is completely reset. In the process, the shock absorber realizes three times of hydraulic damping shock absorption, the first time is that the hydraulic oil in the cavity of the shock absorber piston sleeve 1 flows through the hydraulic oil pipeline 7, the second time is that the hydraulic oil reversely flows through the hydraulic oil pipeline 7, and the third time is that the hydraulic oil flows through the shock absorption one-way valve 13.
Specifically, the middle part of the upper end face of the shock absorber piston sleeve 1 is welded with an upper lifting lug 4, the middle part of the lower end face of the shock absorber piston 2 is welded with a lower lifting lug 5, and the device is convenient to install through the upper lifting lug 4 and the lower lifting lug 5.
Specifically, the outer walls of the damper piston sleeve 1 and the electrostatic armature piston sleeve 6 are respectively adhered with an anti-corrosion layer, and the anti-corrosion of the damper piston sleeve 1 and the electrostatic armature piston sleeve 6 is improved through the anti-corrosion layers.
Specifically, the anti-corrosion layer is a polytetrafluoroethylene layer, the polytetrafluoroethylene layer has the characteristics of acid resistance, alkali resistance and various organic solvents resistance, is almost insoluble in all solvents, and meanwhile, the polytetrafluoroethylene layer has the characteristic of high temperature resistance.
The working principle is as follows:
during the riding process of the bicycle, when the bicycle meets a protruding road surface, the shock absorber is compressed, namely the upper lifting lug 4 and the lower lifting lug 5 are subjected to opposite force. Under the action of opposite forces, hydraulic oil and a pressure reducer spring in the shock absorber piston 2 and the shock absorber piston sleeve 1 are compressed, and the hydraulic oil flows into a cavity formed by the movable armature piston 8 and the electrostatic armature piston sleeve 6 through the hydraulic oil pipeline 7. Under the action of hydraulic oil, the electric pivot piston 8 is displaced and cuts the magnetic force lines of the electrostatic pivot piston sleeve 6 to generate electricity, and the electric pivot return spring 9 is compressed. Since the effective cross-sectional area of the moving armature piston 8 is smaller than the effective cross-sectional area of the shock absorber piston 2, the displacement and velocity of the moving armature piston 8 are greater than those of the shock absorber piston 2.
If the displacement of the shock absorber piston 2 is larger, the position of the movable armature can reach the limit, the pressure of the hydraulic oil exceeds the set pressure value of the power generation one-way valve 12 at the moment, the displacement of the piston 8 of the movable armature is kept unchanged, and the hydraulic oil flows to the other end of the electric armature through the movable armature; when the shock absorber piston 2 reaches the maximum displacement, the shock absorber piston 2 and the shock absorber piston sleeve 1 move in opposite directions, the volume of a cavity of the shock absorber piston 2 is increased, hydraulic oil flows to the cavity of the shock absorber piston sleeve 1 through a hydraulic oil pipeline 7, the moving armature piston 8 is reset under the action of a moving armature return spring 9, and magnetic lines of force are cut again to generate electricity; when the armature piston 8 is reset, the damper piston 2 continues to move, and the aforementioned hydraulic oil flowing through the power generation check valve 12 now flows in reverse through the damper check valve 13 until the damper piston 2 is completely reset. In the process, the shock absorber realizes three times of hydraulic damping shock absorption, the first time is that the hydraulic oil in the cavity of the shock absorber piston sleeve 1 flows through the hydraulic oil pipeline 7, the second time is that the hydraulic oil reversely flows through the hydraulic oil pipeline 7, and the third time is that the hydraulic oil flows through the shock absorption one-way valve 13.
If the displacement of the shock absorber piston 2 is small, the position of the movable armature cannot reach the limit position, the pressure of the hydraulic oil cannot reach the set pressure of the power generation check valve 12 at the moment, and the displacement of the movable armature piston 8 and the displacement of the shock absorber piston 2 reciprocate in a fixed proportion, so that the power generation by cutting magnetic lines of force twice and the shock absorption by hydraulic damping twice are realized.
Because the shock absorption of the bicycle is uncertain movement, the electricity generated by the power generation device is stored in the electricity storage device after being regulated by the voltage regulation device, and the electricity can be used for movement power consumption equipment.
The beneficial effects and characteristics of this scheme:
1. the shock absorber piston 2 and the moving armature piston 8 adopt different effective sectional area designs, and can amplify the movement of a smaller shock absorber to improve the power generation frequency and the power generation capacity.
2. The scheme adopts the design that the shock absorber and the power generation device are separated, so that the failure rate and the repair cost of the whole set of device can be effectively reduced; and the hydraulic oil pipeline 7 is adopted for connection, which is beneficial to arrangement on the vehicle.
3. The scheme of this scheme provides multiple spring action and multiple shock attenuation process, is favorable to improving the travelling comfort of bicycle.
4. This scheme not only can enlarge less bumper shock absorber motion, has still set up safeguard measure to prevent too big shock attenuation motion to destroy power generation facility, improved the security of whole equipment.
5. The electric armature piston 8 of the scheme is soaked in oil all the time, so that lubrication and cooling of the electric armature piston are facilitated, and safety of the device is improved.
6. The scheme provided by the scheme can generate electricity in the reciprocating process of the shock absorber.
Therefore, the scheme improves the power generation frequency, improves the power generation capacity, can effectively reduce the failure rate and the repair cost of the whole set of device, adopts the hydraulic oil pipeline 7 to be connected with the hydraulic oil pipeline, is favorable for the arrangement on a vehicle, and is favorable for improving the driving comfort of the bicycle and the safety of the whole set of device under the action of multiple springs and multiple damping processes.
