[0039] Please refer to Figures 1 to 7 The embodiment of the utility model provides a kind of power generation module 100.The power generation module 100 includes base 1 and the transmission member 2, elastic member 3 and control panel 4 assembled in base 1.Control panel 4 is arranged on base 1, transmission member 2 is arranged above control panel 4, and elastic member 3 is connected to one end of transmission member 2.

[0040] The base 1 has a first end and a second end arranged oppositely. The base 1 is provided with a first limiting portion 11 and a second limiting portion 12 arranged along the longitudinal direction thereof, for limiting the transmission member 2. Specifically, the first limiting portion 11 is arranged at the first end, and the second limiting portion 12 is arranged at the second end. The first limiting portion 11 is provided with an inclined slot 111, which has a third end close to the first end and a fourth end away from the first end. The third end and the fourth end are not at the same height from the base 1, i.e. the third end and the fourth end are not at the same height. The second limiting portion 12 is provided with a horizontally arranged sliding groove 121, which includes a fifth end away from the second end and a sixth end close to the second end, and the fifth end and the sixth end are at the same height.

[0041] Please refer to Figures 2 to 3As shown, the transmission member 2 comprises a main body 21, a first connecting portion 24 and a second connecting portion 25 arranged on both sides of the main body 21 in the longitudinal direction. The main body 21 has a pressing end 27 and a reset end 28 arranged oppositely. The first connecting portion 24 is located at the pressing end 27, and the second connecting portion 25 is located at the reset end 28. The pressing end 27 is movably connected to the first end of the base 1, and the reset end 28 is movably connected to the second end of the base 1 through the elastic member 3. The pressing end 27 has a first position and a second position. When the pressing end 27 is in the first position, the first connecting portion 24 is located at the third end of the slot 111. When the pressing end 27 is in the second position, the first connecting portion 24 is located at the fourth end of the slot 111. The reset end 28 has a third position and a fourth position. When the reset end 28 is in the third position, the second connecting portion 25 is located at the fifth end of the sliding groove 121. When the reset end 28 is in the fourth position, the second connecting portion 25 is located at the sixth end of the sliding groove 121. Moreover, the first position and the second position of the pressing end 27 correspond to the third position and the fourth position of the reset end 28, respectively. A receiving space is arranged in the middle of the main body 21 and surrounded by the mounting wall 22. A limiting groove 23 is arranged on the mounting wall 22, and the first boss and the second boss are arranged in the limiting groove 23 in an up-down manner.

[0042] The first connecting part 24 is adapted to the first limiting part 11, and the second connecting part 25 is adapted to the second limiting part 12. The first connecting part 24 is slidably connected to the slot 111. Specifically, the first connecting part 24 extends into the slot 111 and can slide along the slot 111, so that the pressing end 27 changes between the first position and the second position, that is, the transmission part 2 is displaced in the vertical direction. The second connecting part 25 is slidably connected to the sliding groove 121. Specifically, the second connecting part 25 extends into the sliding groove 121 and can slide along the sliding groove 121, so that the reset end 28 changes between the third position and the fourth position, that is, the transmission part 2 is displaced in the horizontal direction. The design of the inclined slot 111 makes the first connecting part 24 slide from the third end to the fourth end of the slot 111 during the downward movement of the transmission part 2, and the first connecting part 24 not only produces a vertical displacement, but also moves in the horizontal direction, increasing the flexibility of displacement control. The external force drives the transmission part 2 to move downward, and the pressing end 27 changes from the first position to the second position. The first connecting part 24 of the transmission part 2 moves downward in the inclined slot 111, and the first connecting part 24 slides from the third end to the fourth end of the slot 111. The first connecting part 24 produces vertical and horizontal displacement components during the downward movement, and the movement of the first connecting part 24 in the horizontal direction makes the transmission part 2 move as a whole towards the elastic member 3. Further, the second connecting part 25 moves in the sliding groove 121 towards the elastic member 3, and at this time the second connecting part 25 slides from the fifth end to the sixth end of the sliding groove 121, and the reset end 28 changes from the third position to the fourth position, so that the transmission part 2 can move relative to the base 1, that is, move towards the elastic member 3 and further compress the elastic member 3 in the horizontal direction. When the external force disappears, the elastic member 3 resets and pushes the transmission part 2 to move reversely, that is, the transmission part 2 moves away from the elastic member 3. The second connecting part 25 slides in the sliding groove 121 away from the elastic member 3, and the reset end 28 changes from the fourth position to the third position, and drives the first connecting part 24 to slide in the slot 111 away from the elastic member 3. The first connecting part 24 will move upwards along the shape of the slot 111, and the pressing end 27 changes from the second position to the first position, so that the transmission part 2 moves upwards to reset.

[0043] In this embodiment, the first connecting part 24 and the second connecting part 25 are shaft structures arranged on both sides of the longitudinal direction of the main body part 21, specifically pin shafts. The shaft structure can reduce the friction of the first connecting part 24 and the second connecting part 25 during sliding. Compared with planar contact, the contact area of the shaft structure is smaller, so the frictional resistance is lower, to facilitate smooth sliding of the first connecting part 24 and the second connecting part 25.

[0044] In some embodiments, the transmission part 2 is made of plastic material, such as pc, to reduce the overall manufacturing cost. The second connecting part 25 is provided with an inclined guide surface on the side facing the second limiting part 12. Specifically, as shown inFigure 3 As shown, an inclined guide surface is arranged below the end surface of the second connecting part 25 and extends downwardly from the end surface. Since the pc material has a certain elasticity, during assembly, the inclined guide surface can adapt to slight deviations during assembly by virtue of the elastic properties of the material, and the inclined guide surface can guide the second connecting part 25 to be installed into the second limiting part 12.

[0045] Preferably, the transmission member 2 is further provided with an elastic arm 26 extending from the main body 21 towards the base 1. The elastic arm 26 is suspended in a natural state and maintains a certain distance from the base 1. That is, the elastic arm 26 is arranged in a spaced manner from the base 1 in a natural state. When an external force drives the transmission member 2 to move downwardly, the elastic arm 26 will abut against the control plate 4, and at this time, the elastic arm 26 is in a compressed state. When the external force disappears, the elastic arm 26 resets and provides an upward force to the transmission member 2, so as to help the transmission member 2 to reset quickly and stably, thereby improving the hand feeling of pressing the transmission member 2.

[0046] Further, the elastic arm 26 is arranged at an angle with respect to the plane on which the transmission member 2 is located, and functions as a buffer when the elastic arm 26 abuts against the control plate 4, thereby helping to reduce the direct impact between the transmission member 2 and the control plate 4 and reducing the risk of wear and damage of the parts. Preferably, the bottom of the elastic arm 26 is provided with a reinforcing rib 261, so as to strengthen the structural strength of the elastic arm 26 and buffer the impact force when the elastic arm 26 abuts against the control plate 4.

[0047] The elastic member 3 is located on the side of the transmission member 2 close to the second limiting part 12, and in this embodiment, the elastic member 3 is a spring. The side of the transmission member 2 close to the elastic member 3 is provided with a fixed column, and the base 1 is provided with a fixed seat. One end of the elastic member 3 is sleeved on the fixed seat, and the other end of the elastic member 3 is sleeved on the fixed column. The two ends of the elastic member 3 respectively abut against the fixed seat of the base 1 and the transmission member 2, and the elastic member 3 is pressed and in a force storage state. When an external force is applied to the transmission member 2, the first connecting part 24 slides along the slot 111, and the second connecting part 25 slides along the sliding groove 121, and the transmission member 2 moves towards the elastic member 3, which further compresses the elastic member 3.

[0048] Please refer to Figure 4As shown, the control plate 4 is integrated with the power generation part 5 and the signal button 6. The power generation part 5 is fixed on the control plate 4 and located in the accommodating space of the transmission part 2, and the end of the power generation part 5 is connected with the transmission part 2. The power generation part 5 comprises a rotatingly connected magnetic part 51 and a power generation part 52, and the end of the magnetic part 51 is connected with the transmission part 2. Specifically, the magnetic part 51 comprises a magnet 511 and an iron sheet 512 extending from the end of the magnet 511 towards the transmission part 2, the iron sheet 512 at least partially penetrates through the limiting groove 23 of the transmission part 2, and the iron sheet 512 is located between the first boss and the second boss. The top of the iron sheet 512 abuts against the first boss of the limiting groove 23, and the bottom of the iron sheet 512 abuts against the second boss, so as to limit the iron sheet 512 in the limiting groove 23 and synchronize the movement of the transmission part 2 and the magnetic part 51.

[0049] The power generation part 52 is provided with a coil (not shown). The power generation part 5 realizes energy conversion through the rotatingly connected magnetic part 51 and power generation part 52. When the transmission part 2 moves, the magnetic part 51 will move synchronously, i.e. the magnetic part 51 will rotate relative to the power generation part 52 under the driving of the external force, at this time the magnetic induction lines of the coil are cut, and the power generation part 52 is driven to generate electric energy. In this way, the movement energy of the transmission part 2 is effectively utilized to be converted into electric energy for other devices or systems, and the energy utilization rate and conversion efficiency are improved.

[0050] Specifically, the external force drives the transmission part 2 to move downward, the pressing end 27 changes from the first position to the second position, the first connecting part 24 of the transmission part 2 moves downward in the inclined slot 111 and drives the magnetic part 51 to rotate downward relative to the power generation part 52, the second connecting part 25 moves in the sliding groove 121 towards the elastic part 3, and the reset end 28 changes from the third position to the fourth position, so that the transmission part 2 can move relative to the base 1, i.e. moves towards the elastic part 3 and further compresses the elastic part 3. When the external force disappears, the compressed elastic part 3 starts to reset and pushes the transmission part 2 to move reversely, the second connecting part 25 slides in the sliding groove 121 towards the elastic part 3, the reset end 28 changes from the fourth position to the third position and drives the first connecting part 24 to slide in the slot 111 towards the elastic part 3, the first connecting part 24 will move upward along the shape of the slot 111, the pressing end 27 changes from the second position to the first position, and the transmission part 2 moves upward to reset. Further, the transmission part 2 drives the magnetic part 51 to rotate upward relative to the power generation part 52 to reset. In this process, when the pressing end 27 changes between the first position and the second position, the power generation part 5 is touched by the transmission part 2 to generate electricity. Specifically, the transmission part 2 drives the magnetic part 51 to rotate upward or downward relative to the power generation part 52, the magnetic part 51 cuts the magnetic induction lines of the coil, and the power generation part 52 generates electricity.

When an external force presses the key part 120, the key part 120 can move relative to the base 1 of the power generation module 100 under the external force pressing, so that the power generation module 100 generates electricity. The switch 200 integrates the power generation module 100, and converts the mechanical energy generated when the external force presses the key part 120 into electrical energy, so that the power supply and signal transmission of the switch 200 can be realized without external power supply, which not only reduces energy consumption, but also meets the concept of green environmental protection.
