[0002] In modern engineering and mechanical design, shock absorbers are devices that protect structures and equipment from damage by reducing or absorbing mechanical vibrations and shock waves. Conventional shock absorption technologies mainly include springs, vibration dampers, and dampers, which reduce the impact of vibrations on structures by absorbing and dissipating vibration energy. However, these technologies focus primarily on vibration suppression and do not convert vibration energy into other forms of energy, so they cannot fully utilize vibration energy.

[0009] A shock-absorbing spring is fitted over the outer side of the power transmission rod, one end of the shock-absorbing spring is installed while pressing on the generator, and the other end is fixed to one side of the power transmission rod near the vibration source by a bolt fastening device;

[0010] The shock absorber for converting vibration energy into electrical energy is characterized by a vibration source vibrating and operating alternately with a shock-absorbing spring to drive a power transmission rod to reciprocate along the inner chamber of the rotor shaft, thereby rotating the rotor in one direction through a drive head.

[0011] As an improved technology, the power transmission rod is provided with an extension at one end inserted into the inner chamber of the rotor shaft, the drive head is installed on the extension so as to be rotatable around the extension, and a slider is installed on the drive head to be fitted with a spiral slanted surface.

[0012] As an improved technology, the length of the extension is longer than the length of the drive head, so that the drive head can slide along the axial direction of the extension.

[0013] As an improved technology, the unidirectional rotation mechanism includes a latch installed at the bottom of a drive head and a reverse latch fixed to a power transmission rod, and the latch and the reverse latch each have an inclined portion and a second inclined portion formed therein that engage with each other.

[0014] As an improved technology, the number of the above latches and reverse latches is multiple.

[0015] As an improved technology, the number of the spiral curved surfaces is multiple and is arranged along the axis of the rotor shaft.

The present invention can realize the effect of converting vibration energy into electrical energy by fully utilizing vibration energy, and can reduce dependence on fossil fuels and reduce environmental pollution and greenhouse gas emissions.

[0020] 2. In addition to shock absorption through shock-absorbing springs, the present invention can effectively dampen vibrations even during the process of driving the rotation of the generator rotor while the power transmission rod moves within the inner chamber of the rotor shaft. Compared to conventional single shock absorbers, the shock absorption effect is superior.

Specific details for implementing the invention

[0024] Hereinafter, the present invention will be described in detail through specific embodiments to better understand the invention, but the following embodiments do not limit the scope of protection of the present invention.

[0025] Example 1

[0026] The present embodiment discloses a shock absorber for converting vibration energy into electrical energy, comprising a generator (1) having a stator and a rotor inside, wherein the rotor shaft (2) of the rotor is in the shape of a hollow pipe and a rotor shaft inner chamber (21) is installed along the axis inside, and a spiral curved surface (22) is formed on the rotor shaft inner chamber (21).

[0027] The generator (1) is further equipped with a power transmission rod (3), one end of the power transmission rod (3) is inserted into the rotor shaft inner chamber (21) and the other end is fixed to an external vibration source (4), and a drive head (5) is installed on the end of the power transmission rod (3) inserted into the rotor shaft inner chamber (21) to be fitted with a spiral curved surface (22), and a unidirectional rotation mechanism (6) is installed inside the drive head (5).

[0028] The vibration source (4) vibrates to drive the power transmission rod (3) so that it reciprocates along the rotor shaft inner chamber (21), thereby rotating the rotor in one direction through the drive head (5) to achieve the purpose of power generation.

[0029] The power transmission rod (3) is provided with an extension (31) at one end of the rod inserted into the rotor shaft inner chamber (21), and the drive head (5) is installed on the extension (31) so as to be rotatable around the extension (31), and the drive head (5) is provided with a slider (51) that fits into the spiral curved surface (22).

[0030] The length of the extension (31) is longer than the length of the drive head (5), so that the drive head (5) can slide along the axial direction of the extension (31).

[0031] The unidirectional rotation mechanism (6) includes a latch (61) installed at the bottom of the drive head (5) and a reverse latch (62) fixed to the power transmission rod (3), and the latch (61) and the reverse latch (62) each have an inclined portion (63) and a second inclined portion (64) formed therein that engage with each other.

[0032] Since the drive head (5) slides along the axial direction of the extension (31), there is an assembly gap between the latches (61, 62). As shown in FIG. 5, when the vibration source (4) drives the power transmission rod (3) to move to the right, the drive head (5) is locked in place through the latch (61) and the reverse latch (62) under the guidance of the inclined section (63) and the second inclined section (64). Thus, the drive head (5) is pushed to the right to move along the spiral slope (22), generating a rotational torsional force to rotate the rotor. When the vibration source (4) drives the power transmission rod (3) to move to the left, the latch (61) is disengaged from the reverse latch (62), releasing the rotation lock on the drive head (5) and achieving the objective of rotating only the rotor in one direction.

[0033] In this embodiment, the number of latches (61) and reverse latches (62) is two each. The number of spiral curved surfaces (22) is three and is arranged along the axis of the rotor shaft (2). The number of sliders (51) is the same as the number of spiral curved surfaces (22).

[0034] The cross-section of the slider (51) is formed in an inverted right-angled trapezoid.

[0035] In this embodiment, a shock absorbing spring (7) is placed on the outer side of the power transmission rod (3), and one end of the shock absorbing spring (7) is installed by pressing on the generator, while the other end is fixed by a bolt fastening device (71) on one side of the power transmission rod (3) near the vibration source (4). The shock absorbing spring (7) can perform shock absorption and repulsion functions. As shown in FIG. 1, when the power transmission rod (3) moves to the left, the shock absorbing spring (7) is compressed to provide shock absorption and cushioning effects; when the vibration force to the left disappears, the compressed shock absorbing spring (7) is repulsed and pushes the power transmission rod (3) to the right, thereby disengaging the reverse latch (62) located on the power transmission rod (3) from the latch (62) and achieving the purpose of unlocking. After unlocking, the drive head (5) rotates along the rotor shaft (2) by means of the spiral curved surface (22) within the rotor shaft inner chamber (21), and simultaneously moves to the left by means of the extension (31) to prepare for the next rotation of the rotor shaft (2). By repeating this process, the objective of continuously rotating the rotor shaft (2) in one direction can be achieved.

[0036] Although specific embodiments of the present invention have been described in detail above, this is merely an example, and the present invention is not identical to the specific embodiments described above. Those skilled in the art would understand that equivalent variations and alternatives of the present invention are also included within the scope of the present invention. Therefore, all equivalent variations and modifications that do not depart from the technical spirit and scope of the present invention should be included within the scope of the present invention.
