[0046] The present application discloses a micro-generator module. Figures 1 to 3 , including a metal shell 100, a rocker arm 200, an elastic member 300, a magnetic assembly 400 and an electromagnetic coil assembly 500, including: the metal shell 100 includes a bottom plate 110 and two side plates 120, the two side plates 120 are respectively connected to the two sides of the bottom plate 110, and a magnetic cavity 140 is formed between the bottom plate 110 and the two side plates 120; the rocker arm 200 includes a magnetic storage part 210, a rotating arm 220 and a storage arm 230, and the magnetic storage part 210 is located at the guide In the magnetic cavity 140, the rotating arm 220 is connected to the magnetic storage portion 210 and extends to the inner side of the front end of the magnetic cavity 140 to be rotatably connected to the front end of the side plate 120. The storage arm 230 is connected to the magnetic storage portion 210 and extends to the inner side of the tail end of the magnetic cavity 140; the elastic member 300 is disposed in the magnetic cavity 140 and connected to the storage arm 230 to reset the rocker arm 200 after being pressed; the magnetic assembly 400 includes a permanent magnet 410, a first magnetic conductive sheet 420 and a second magnetic conductive sheet 430, the permanent magnet 410 is arranged in the magnetic storage part 210, the first magnetic conductive sheet is arranged on the side of the magnetic storage part 210 close to the bottom plate 110, and the second magnetic conductive sheet is arranged on the side of the permanent magnet 410 away from the bottom plate 110; the electromagnetic coil assembly 500 includes an iron core 510 and a coil 520, the iron core 510 is located on the side of the magnetic storage part 210 with the rotating arm 220 and is connected to the metal shell 100, and the coil 5 20 is wound around the outside of the iron core 510; wherein the rocker arm 200 can be pressed to switch between a first posture and a second posture. When the rocker arm 200 is in the first posture, the first magnetic conductive sheet 420 is in contact with and connected to the iron core 510, and the second magnetic conductive sheet 430 is in contact with and connected to the metal shell 100; when the rocker arm 200 is in the second posture, the first magnetic conductive sheet 420 is in contact with and connected to the metal shell 100, and the second magnetic conductive sheet 430 is in contact with and connected to the iron core 510.

[0047] Specifically, when external power supply is required, the elastic force of the elastic member 300 is overcome, and the user pushes the rocker member 200 to rotate through the magnetic storage portion 210 or the force storage arm 230 to switch the rocker member 200 from the first posture to the second posture; when the user releases the magnetic storage portion 210 or the force storage arm 230, the rocker member 200 is reset from the second posture to the first posture under the action of the elastic member 300, and so on, the rocker member 200 switches back and forth between the first posture and the second posture. Among them, when the rocker arm part 200 is maintained in the first posture under the action of the elastic part 300, the first magnetic conductive sheet 420 is in contact and connected with the iron core 510, and the second magnetic conductive sheet 430 is in contact and connected with the metal shell 100; when the user pushes the magnetic storage part 210, the magnetic storage part 210 overcomes the elastic force of the elastic part 300, the first magnetic conductive sheet 420 is in contact and connected with the metal shell 100, and the second magnetic conductive sheet 430 is in contact and connected with the iron core 510, thereby, the magnetic component 400 moves relative to the coil, so that the coil cuts the magnetic flux lines to generate current.

[0048] It can be understood that the micro-generator module adopts the above-mentioned structural form, that is, a metal shell 100 is used to form a magnetic cavity 140, and the rocker arm part 200, the elastic part 300, the magnetic component 400 and the electromagnetic coil component 500 are all arranged in the magnetic cavity 140, and the rocker arm part 200 is connected to the elastic part 300 through the backward extending force storage arm 230. Such a setting can effectively reduce the contact angle between the first magnetic conductive sheet 420, the second magnetic conductive sheet 430 and the iron core 510 and the metal shell 100, thereby increasing the contact area between the first magnetic conductive sheet 420, the second magnetic conductive sheet 430 and the iron core 510 and the metal shell 100, thereby improving the magnetic exchange efficiency. As a result, the power generation and stability of the micro-generator module are effectively guaranteed.

[0049] In other possible embodiments, when the rocker arm 200 is in the first position, the second magnetic conductive sheet 430 is in contact with the metal housing 100; when the rocker arm 200 is in the second position, the first magnetic conductive sheet 420 is not in contact with the metal housing 100; or, when the rocker arm 200 is in the first position, the second magnetic conductive sheet 430 is not in contact with the metal housing 100; when the rocker arm 200 is in the second position, the first magnetic conductive sheet 420 is in contact with the metal housing 100; or, when the rocker arm 200 is in the first position, the second magnetic conductive sheet 430 is not in contact with the metal housing 100; when the rocker arm 200 is in the second position, the first magnetic conductive sheet 420 is not in contact with the metal housing 100. It is understood that the rocker arm 200 adopts the above-mentioned working mode during application to avoid or reduce collision between the rocker arm and the metal housing 100, thereby reducing noise generated by the micro-generator module during application.

[0050] In order to realize that the elastic member 300 can be installed in the magnetic cavity 140 and provide elastic force for the force storage arm 230 located in the magnetic cavity 140, in some embodiments, refer to Figures 2 to 3 The elastic member 300 includes two spring coils 310, a first torsion arm 320 and a second torsion arm 330. The two side plates 120 are both provided with a first bent portion 123 bent toward the magnetic conductive cavity 140. The two spring coils 310 are respectively sleeved on the first bent portion 123. Each spring coil 310 is provided with a first torsion arm 320 extending roughly along its tangential direction. The first torsion arm 320 is abutted against the bottom plate 110 of the metal shell 100. Each spring coil 310 is respectively provided with the first torsion arm 320 to abut against the metal shell 100. The second torsion arm 330 is U-shaped and connected between the two spring coils 310. The cross bar of the second torsion arm 330 abuts against the side of the storage arm 230 close to the bottom plate 110. Thus, the elastic member 300 provides an elastic force for the storage arm 230 to move away from the bottom plate 110.

[0051] It will be appreciated that the aforementioned structural form of the elastic member 300 and the metal housing 100 allows the elastic member 300 to be conveniently installed within the magnetic cavity 140 and provides the elastic member 300 with a stable and sufficiently large elastic force, thereby returning the rocker arm 200 to its initial position after being pressed, thereby completing the transition between the second and first postures. In addition to the convenient installation of the elastic member 300 within the magnetic cavity 140, the aforementioned structural form of the metal housing 100 also provides a simple structure for easy manufacturing.

[0052] Furthermore, both side plates 120 are provided with a second bent portion 124 bent toward the magnetic cavity 140, and the second bent portion 124 is used to abut against the side of the second torsion arm 330 away from the bottom plate 110, thereby, the second bent portion 124 is used to limit the second torsion arm 330 to remain in the magnetic cavity 140; at the same time, the rocker arm 200 is used to limit the movement range of the second torsion arm 330 when resetting, thereby limiting the second torsion arm 330 from excessively acting on the storage arm 230, thereby preventing the second magnetic conductive sheet 430 from excessively colliding with the metal shell 100, thereby ensuring the application safety of the second magnetic conductive sheet 430, and effectively guaranteeing the service life of the micro-generator module.

[0053] To facilitate installation of the magnetic assembly 400, in some embodiments, see Figures 2 to 4, a mounting groove 211 is provided on the side of the magnetic storage part 210 close to the iron core 510, and a mounting boss 212 is provided on the left and right opposite sides of the mounting groove 211, a portion of the first magnetic conductive sheet 420 is clamped in the mounting groove 211, and the two sides of the first magnetic conductive sheet 420 are respectively pressed against the side of the mounting groove 211 close to the bottom plate 110 and the side of the mounting boss 212 close to the bottom plate 110, and the other part of the first magnetic conductive sheet 420 is exposed on the side of the magnetic storage part 210 close to the iron core 510; similarly, a portion of the second magnetic conductive sheet 430 is clamped in the mounting groove 211, and the two sides of the second magnetic conductive sheet 430 are respectively pressed against the side of the mounting groove 211 away from the bottom plate 110 and the side of the mounting boss 212 away from the bottom plate 110, and the other part of the second magnetic conductive sheet 430 is exposed on the side of the magnetic storage part 210 close to the iron core 510. The permanent magnet 410 is clamped between the two mounting bosses 212 to be located between the first magnetic conductive sheet 420 and the second magnetic conductive sheet 430. The end of the iron core 510 closest to the magnetic housing portion 210 is located between the first magnet surface and the second magnetic conductive sheet 430. Therefore, during the rotation of the magnetic housing portion 210, if the first magnetic conductive sheet 420 is in contact with the iron core 510, the second magnetic conductive sheet 430 and the iron core 510 are separated. If the second magnetic conductive sheet 430 and the iron core 510 are in contact, the first magnetic conductive sheet 420 and the iron core 510 are in contact, thereby cutting the magnetic field and generating electricity.

[0054] It can be understood that the magnetic storage portion 210 is provided with the above-mentioned mounting groove 211, and mounting bosses 212 are provided on the opposite sides of the mounting groove 211. Thus, the first magnetic conductive sheet 420, the second magnetic conductive sheet 430 and the permanent magnet can be conveniently stacked and installed in the mounting groove 211, thereby facilitating the assembly of the micro-generator module.

[0055] In order to facilitate the accurate installation of the iron core 510 in the magnetic cavity 140, more precisely, with respect to the magnetic assembly 400, in some embodiments, see Figure 2 and Figure 3 The micro-generator module also includes a fixed bracket 600 arranged in the magnetic cavity 140, and the fixed bracket 600 is made of insulating material. The fixed bracket 600 is located between the coil 520 and the magnetic storage portion 210. The fixed bracket 600 is provided with a first positioning hole 630 along the length direction of the magnetic cavity 140. The iron core 510 is passed through the first positioning hole 630 to extend between the first magnetic conductive sheet 420 and the second magnetic conductive sheet 430. Thus, the fixed bracket 600 positions the iron core 510, so that the iron core 510 is accurately installed in the magnetic cavity 140 relative to the magnetic component 400, and then the coil 520 sleeved on the outside of the iron core 510 is located in the magnetic cavity 140. Therefore, when the magnetic component 400 is rotating, the coil 520 outputs current evenly to the outside.

[0056] At the same time, the left and right sides of the fixed bracket 600 are respectively provided with limiting protrusions 610 extending toward the side plate 120. The limiting protrusions 610 are located on the side of the rotating arm 220 away from the bottom plate 110. Thus, the limiting protrusions 610 are used to limit the side of the rotating arm 220 away from the bottom plate 110, so that the rotating arm 220 rotates within a set range, thereby ensuring that the rocker arm 200 drives the magnetic assembly 400 to rotate within the effective range of the magnetic cavity 140. As can be seen from the above, through the provision of the fixed bracket 600, the fixed bracket 600 accurately positions the iron core 510 and, by limiting the range of motion of the rotating arm 220, allows the magnetic assembly 400400 to move within the effective range, thereby ensuring that the micro-generator module can generate stable power during operation.

[0057] In order to keep the fixing bracket 600 installed in the magnetic cavity 140, in one possible embodiment, the micro-generator module further includes a retaining member 700. The retaining member 700 is made of a metal material, and the two ends of the retaining member 700 are respectively connected to the side panels 120. For example, the two side panels 120 are respectively provided with a second snap hole 122, and the two ends of the retaining member 700 are respectively inserted into the second snap holes 122, so that the retaining member 700 is installed between the two side panels 120. At the same time, the retaining member 700 has a sufficient width along the front-to-back direction of the magnetic cavity 140. The retaining member 700 is partially pressed against the side of the fixing bracket 600 away from the bottom plate 110 to keep the fixing bracket 600 installed in the magnetic cavity 140, and the other portion is located on the side of the second magnetic conductive sheet 430 away from the second magnetic conductive sheet 430. Therefore, in a specific application, when the rocker arm 200 is in the first posture, the second magnetic conductive sheet 430 contacts and connects with the retaining member 700, thereby forming a magnetic connection with the metal housing 100. At this time, the first magnetic conductive sheet 420 contacts and connects with the side of the iron core 510 closer to the bottom plate 110. When the rocker arm 200 is pressed to switch from the first posture to the second posture, the first magnetic conductive sheet 420 contacts and connects with the bottom plate 110, and the second magnetic conductive sheet 430 is separated from the retaining member 700 and contacts and connects with the side of the iron core 510 farther from the bottom plate 110. As can be seen from the above, through the provision of the retaining member 700, the retaining member 700 not only secures the fixing bracket 600 in the magnetic cavity 140, but also allows the second magnetic conductive sheet 430 to be magnetically connected to the metal housing 100 through the retaining member 700, making the solution more convenient to implement.

[0058] Instead of the above-mentioned retaining member 700, in another possible embodiment, please refer to Figure 6Both side panels 120 are provided with a third bent portion 125 that is bent toward the magnetic cavity 140. The third bent portion 125 has a sufficient width along the front-to-back direction of the magnetic cavity 140. A portion of the third bent portion 125 is pressed against the side of the fixing bracket 600 away from the bottom plate 110 to maintain the fixing bracket 600 installed in the magnetic cavity 140. Another portion of the third bent portion 125 is located on the side of the second magnetic conductive sheet 430 away from the second magnetic conductive sheet 430. Therefore, in a specific application, when the rocker arm 200 is in the first posture, the second magnetic conductive sheet 430 is in contact and connection with the retaining member 700, thereby forming a magnetic connection with the metal housing 100. At this time, the first magnetic conductive sheet 420 is in contact and connection with the side of the iron core 510 closer to the bottom plate 110. When the rocker arm 200 is pressed to switch from the first position to the second position, the first magnetic conductive sheet 420 contacts and connects with the base plate 110, while the second magnetic conductive sheet 430 is separated from the third bent portion 125 and contacts and connects with the side of the core 510 away from the base plate 110. As can be seen from the above, through the provision of the third bent portion 125, the retaining frame not only securely mounts the fixing bracket 600 within the magnetic conductive cavity 140, but also allows the second magnetic conductive sheet 430 to be magnetically connected to the metal housing 100 via the third bent portion 125, making the solution more convenient to implement.

[0059] Further, see Figure 5 The bottom plate 110 is provided with an installation opening 111, and the bottom of the fixing bracket 600 is provided with a raised positioning protrusion 620. When the fixing bracket 600 is installed in the magnetic cavity 140, the positioning protrusion 620 is embedded in the installation opening 111, so that the fixing bracket 600 is accurately installed in the magnetic cavity 140, thereby ensuring that the fixing bracket 600 can accurately position the iron core 510; at the same time, after the fixing bracket 600 is relatively positioned with the bottom plate 110, the retaining member 700 can also more firmly fix the fixing bracket 600 in the magnetic cavity 140.

[0060] In some embodiments, see Figure 2 and Figure 3 The front end of the bottom plate 110 is provided with an end plate portion 130. One end of the iron core 510 is connected to the end plate portion 130, and the other end extends between the first magnetic conductive sheet 420 and the second magnetic conductive sheet 430 so as to be in contact and connected with the first magnetic conductive sheet 420 and the second magnetic conductive sheet 430. A flange 640 is provided on the top of the fixing bracket 600. The coil 520 is held between the end plate portion 130 and the flange 640 of the fixing bracket 600. The side of the flange 640 away from the coil 520 is held against the retaining member 700 or the side of the third bent portion 125. With this arrangement, the coil 520 and the fixing bracket 600 are compactly and firmly installed in the magnetic conductive cavity 140, and assembly is relatively convenient.

[0061] In some embodiments, the end plate portion 130 is provided with a second positioning hole, the first positioning hole 630 is aligned with the second positioning hole, one end of the iron core 510 is inserted and connected to the first positioning hole 630, and the other end of the iron core 510 extends toward the magnetic assembly 400. With this arrangement, the iron core 510 is conveniently installed in the magnetic cavity 140 through the end plate portion 130. It can be understood that the iron core 510 and the metal shell 100 are two independent components. With this arrangement, the iron core 510 can be accurately installed in the magnetic cavity 140, thereby allowing the coil 520 sleeved on the outside of the iron core 510 to cooperate with the magnetic assembly 400. As a result, when the magnetic assembly 400 rotates with the magnetic compartment portion 210, the coil 520 can stably output current.

[0062] In other possible embodiments, see also Figure 7 One end of the iron core 510 is integrally connected to the end plate 130, and the other end of the iron core 510 extends toward the magnetic assembly 400. With this arrangement, the iron core 510 is conveniently installed in the magnetic cavity 140 via the end plate 130. It is understood that the iron core 510 is integrally provided with the metal housing 100. During the manufacturing process of the metal housing 100, the iron core 510 is also manufactured, eliminating the need to manufacture the iron core 510 separately, thereby saving costs.

[0063] In some embodiments, see also Figure 5 The bottom plate 110 is provided with a clearance opening 112 for making way for the magnetic storage portion 210. It is understandable that, through the provision of the clearance opening 112, when the magnetic storage portion 210 is pressed, the clearance opening 112 can make way for the magnetic storage portion 210, thereby allowing the second magnetic conductive sheet 430 to contact and connect with the bottom plate 110, and increasing the contact area between the second magnetic conductive sheet 430 and the iron core 510, thereby improving the magnetic exchange efficiency, and further improving the power generation and stability of the module.

[0064] Second, see Figures 1 to 3 The embodiment of the present application provides an electrical product, including a product body and the above-mentioned micro-motion generator module, wherein the side wall of the front end portion of the side panel 120 is provided with a first snap hole 121, and the first snap hole 121 is used for snap connection with the product body. The product body can be an electronic lock, a power switch, etc. It is understandable that when the micro-motion generator module is applied to the product body, it can be conveniently installed in the product body using the first snap hole 121. The micro-motion generator module of the present application is relatively convenient to apply, and the micro-motion generator module is used to power the product body.

[0065] It can be understood that when an electrical product adopts the above-mentioned micro-generator module, when the micro-generator module needs to supply electricity to the product body, the elastic force of the elastic part 300 is overcome, and the user pushes the rocker part 200 to rotate through the magnetic storage part 210 or the storage arm 230 to switch the rocker part 200 from the first posture to the second posture; when the user releases the magnetic storage part 210, the rocker part 200 switches from the second posture to the first posture under the action of the elastic part 300, and so on, the rocker part 200 switches back and forth between the first posture and the second posture. When the rocker arm 200 is held in the first position by the elastic member 300, the first magnetic conductive sheet 420 is in contact with the iron core 510, and the second magnetic conductive sheet 430 is in contact with the metal housing 100. When the user pushes the magnetic housing 210, the magnetic housing 210 overcomes the elastic force of the elastic member 300, causing the first magnetic conductive sheet 420 to contact the metal housing 100, and the second magnetic conductive sheet 430 to contact the iron core 510. In this way, the magnetic assembly 400 moves relative to the coil, causing the coil to cut through the magnetic flux lines, generating current.

[0066] It can be understood that the micro-generator module adopts the above-mentioned structural form, that is, a metal shell 100 is used to form a magnetic cavity 140, and the rocker arm part 200, the elastic part 300, the magnetic component 400 and the electromagnetic coil component 500 are all arranged in the magnetic cavity 140, and the rocker arm part 200 is connected to the elastic part 300 through the backward extending force storage arm 230. Such a setting can effectively reduce the contact angle between the first magnetic conductive sheet 420, the second magnetic conductive sheet 430 and the iron core 510 and the metal shell 100, thereby increasing the contact area between the first magnetic conductive sheet 420, the second magnetic conductive sheet 430 and the iron core 510 and the metal shell 100, thereby improving the magnetic exchange efficiency. Therefore, the power generation and stability of the micro-generator module are effectively guaranteed, and thus sufficient and stable power can be provided to the product body for product use.

[0067] If the integrated unit is implemented in the form of a software functional unit and sold or used as an independent artifact, it can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present application, or the part that contributes to the prior art, or all or part of the technical solution can be embodied in the form of a software artifact, which is stored in a storage medium and includes several instructions for enabling a computer device (which can be a personal computer, server, or network device, etc.) to execute all or part of the steps of the method described in each embodiment of the present application. The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (ROM, read-only memory), random access memory (RAM, random access memory), disk or optical disk, and other media that can store program code.
