[0002] Currently, the application of passive wireless technology has made great progress. The power supply of many low-power electronic products has successfully broken away from the limitation of batteries and no longer needs batteries. These low-power electronic products can be self-powered by converting the mechanical energy of people operating these devices into electrical energy.

[0003] In related technologies, micro-generator modules typically have a rotating arm that drives a permanent magnet assembly to move relative to a coil unit, thereby generating current in the coil unit. However, due to the large rotation angle of the rotating arm, the contact between the magnetic conductive sheet of the permanent magnet assembly and the iron core of the coil unit is poor, resulting in poor power generation efficiency of the micro-generator module.

[0027] Product itself,

[0028] This includes the aforementioned micro-generator module, used to power the product itself.

[0029] As can be seen from the above technical solutions, the embodiments of this application have the following advantages: When external power needs to be supplied, the user overcomes the elastic force of the elastic element and pushes the rocker arm to rotate through the magnetic housing or the power storage arm, so that the rocker arm switches from the first posture to the second posture; when the user releases the magnetic housing or the power storage arm, the rocker arm switches from the second posture to the first posture under the action of the elastic element, and so on, the rocker arm switches back and forth between the first posture and the second posture. Among them, when the rocker arm is held in the first posture under the action of the elastic element, the first magnetic sheet is in contact with the iron core, and the second magnetic sheet is in contact with the metal shell; when the user pushes the magnetic housing, the magnetic housing overcomes the elastic force of the elastic element, the first magnetic sheet is in contact with the metal shell, and the second magnetic sheet is in contact with the iron core. As a result, the magnetic component moves relative to the coil, so that the coil cuts the magnetic field lines to generate current.

[0030] It is understandable that the micro-generator module adopts the above-mentioned structural form, that is, it uses a metal shell to form a magnetic cavity, and the rocker arm, elastic element, magnetic component and electromagnetic coil component are all set in the magnetic cavity. The rocker arm is connected to the elastic element through a rearward-extending energy storage arm. This arrangement can effectively reduce the contact angle between the first magnetic sheet, the second magnetic sheet and the iron core and the metal shell, thereby increasing the contact area between the first magnetic sheet, the second magnetic sheet and the iron core and the metal shell, and thus improving the magnetic force exchange efficiency. As a result, the power generation and stability of the micro-generator module are effectively guaranteed. Attached Figure Description

[0046] This application discloses a micro-generator module. Please refer to [link / reference]. Figures 1 to 3 The assembly includes a metal casing 100, a rocker arm 200, an elastic element 300, a magnetic component 400, and an electromagnetic coil assembly 500. The metal casing 100 includes a base plate 110 and two side plates 120, with the two side plates 120 respectively connected to both sides of the base plate 110, forming a magnetically conductive cavity 140 between the base plate 110 and the two side plates 120. The rocker arm 200 includes a magnetic housing 210, a rotating arm 220, and a power storage arm 230. The magnetic housing 210 is located within the magnetically conductive cavity 500. Inside the magnetic cavity 140, the rotating arm 220 is connected to the magnetic chamber 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 accumulating arm 230 is connected to the magnetic chamber 210 and extends to the inner side of the rear end of the magnetic cavity 140. The elastic element 300 is disposed inside the magnetic cavity 140 and connected to the accumulating arm 230 to reset the rocker arm 200 after being pressed. The magnetic assembly 400 includes a permanent magnet. 410. A first magnetic sheet 420 and a second magnetic sheet 430; a permanent magnet 410 is disposed in the magnetic chamber 210; the first magnetic sheet is disposed on the side of the magnetic chamber 210 near the base plate 110; the second magnetic sheet is disposed on the side of the permanent magnet 410 away from the base 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 chamber 210 with the rotating arm 220 and is connected to the metal housing 100; the coil 520... 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 sheet 420 is in contact with the iron core 510 and the second magnetic sheet 430 is in contact with the metal shell 100; when the rocker arm 200 is in the second posture, the first magnetic sheet 420 is in contact with the metal shell 100 and the second magnetic sheet 430 is in contact with the iron core 510.

[0047] Specifically, when external power is needed, the user overcomes the elastic force of the elastic element 300 by pushing the rocker arm 200 to rotate through the magnetic chamber 210 or the power storage arm 230, so that the rocker arm 200 switches from the first posture to the second posture. When the user releases the magnetic chamber 210 or the power storage arm 230, the rocker arm 200 returns to the first posture from the second posture under the action of the elastic element 300. In this way, the rocker arm 200 switches back and forth between the first posture and the second posture. When the rocker arm 200 is held in the first posture by the elastic member 300, the first magnetic sheet 420 is in contact with the iron core 510 and the second magnetic sheet 430 is in contact with the metal shell 100. When the user pushes the magnetic chamber 210, the magnetic chamber 210 overcomes the elastic force of the elastic member 300, the first magnetic sheet 420 is in contact with the metal shell 100 and the second magnetic sheet 430 is in contact with the iron core 510. As a result, the magnetic component 400 moves relative to the coil, thereby causing the coil to cut the magnetic field lines to generate current.

[0048] It is understandable that the micro-generator module adopts the above-mentioned structural form, that is, it uses a metal shell 100 to form a magnetic cavity 140, and the rocker arm 200, elastic element 300, magnetic component 400 and electromagnetic coil component 500 are all set in the magnetic cavity 140. The rocker arm 200 is connected to the elastic element 300 through a rearwardly extending storage arm 230. This arrangement can effectively reduce the contact angle between the first magnetic sheet 420, the second magnetic sheet 430 and the iron core 510 and the metal shell 100, thereby increasing the contact area between the first magnetic sheet 420, the second magnetic sheet 430 and the iron core 510 and the metal shell 100, and thus improving the magnetic force 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 posture, the second magnetic sheet 430 is in contact with the metal housing 100; when the rocker arm 200 is in the second posture, the first magnetic sheet 420 is not in contact with the metal housing 100; or, when the rocker arm 200 is in the first posture, the second magnetic sheet 430 is not in contact with the metal housing 100; when the rocker arm 200 is in the second posture, the first magnetic sheet 420 is in contact with the metal housing 100; or, when the rocker arm 200 is in the first posture, the second magnetic sheet 430 is not in contact with the metal housing 100; when the rocker arm 200 is in the second posture, the first magnetic sheet 420 is not in contact with the metal housing 100. It is understood that the rocker arm 200 adopts the above-described working form during application to avoid or reduce collisions between the rocker arm and the metal housing 100, thereby reducing the noise generated by the micro-generator module during application.

[0050] In order to enable the elastic element 300 to be installed within the magnetic cavity 140 and to provide elastic force to the energy storage arm 230 located in the magnetic cavity 140, in some embodiments, please refer to Figures 2 to 3 The elastic element 300 includes two spring coils 310, a first torsion arm 320, and a second torsion arm 330. Both side plates 120 are provided with a first bending portion 123 that bends toward the magnetic cavity 140. The two spring coils 310 are respectively sleeved on the first bending portion 123. Each spring coil 310 is provided with a first torsion arm 320 extending approximately along its tangential direction. The first torsion arm 320 abuts against the bottom plate 110 of the metal shell 100. Each spring coil 310 is provided with a 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 crossbar of the second torsion arm 330 abuts against the side of the power storage arm 230 near the bottom plate 110. Thus, the elastic element 300 provides the power storage arm 230 with an elastic force away from the bottom plate 110.

[0051] It is understandable that the elastic element 300 and the metal housing 100 adopt the above-described structural form. The elastic element 300 can be easily installed inside the magnetic cavity 140, and a stable and sufficiently large elastic force is provided for the elastic element 300, so that the rocker arm 200 can be reset to its initial position after being pressed, thereby completing the transition between the second posture and the first posture. In addition to the elastic element 300 being easily installed inside the magnetic cavity 140, the metal housing 100 adopts the above-described structural form, and the metal housing 100 has a simple structure and is easy to manufacture.

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

[0053] For ease of installation of the magnetic assembly 400, please refer to the following embodiments in some cases. Figures 2 to 4The magnetic cavity 210 has a mounting groove 211 on the side near the iron core 510, and mounting bosses 212 on opposite sides of the mounting groove 211. A portion of the first magnetic sheet 420 is engaged in the mounting groove 211, and both sides of the first magnetic sheet 420 abut against the side of the mounting groove 211 near the base plate 110 and the side of the mounting bosses 212 near the base plate 110, respectively. The other portion of the first magnetic sheet 420 is exposed on the side of the magnetic cavity 210 near the iron core 510. Similarly, a portion of the second magnetic sheet 430 is engaged in the mounting groove 211, and both sides of the second magnetic sheet 430 abut against the side of the mounting groove 211 away from the base plate 110 and the side of the mounting bosses 212 away from the base plate 110, respectively. The other portion of the second magnetic sheet 430 is exposed on the side of the magnetic cavity 210 near the iron core 510. The permanent magnet 410 is engaged between the two mounting bosses 212, positioned 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 chamber 210 is located between the first magnet surface and the second magnetic conductive sheet 430. Thus, during rotation of the magnetic chamber 210, if the first magnetic conductive sheet 420 contacts the iron core 510, the second magnetic conductive sheet 430 is separated from the iron core 510; if the second magnetic conductive sheet 430 is in contact with the iron core 510, the first magnetic conductive sheet 420 is in contact with the iron core 510, thereby achieving magnetic field cutting and power generation.

[0054] It is understood that the magnetic housing 210 is provided with the aforementioned mounting groove 211, and mounting bosses 212 are provided on both sides of the mounting groove 211. Thus, the first magnetic sheet 420, the second magnetic 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] To facilitate precise installation of the iron core 510 within the magnetic cavity 140, and more precisely, relative to the magnetic assembly 400, in some embodiments, please refer to... Figure 2 and Figure 3 The micro-generator module also includes a fixed bracket 600 disposed in the magnetic cavity 140. The fixed bracket 600 is made of insulating material and is located between the coil 520 and the magnetic chamber 210. The fixed bracket 600 has a first positioning hole 630 along the length of the magnetic cavity 140. The iron core 510 passes through the first positioning hole 630 and extends between the first magnetic sheet 420 and the second magnetic 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. This allows the coil 520, which is sleeved on the outside of the iron core 510, to be located in the magnetic cavity 140. Thus, during the rotation of the magnetic component 400, the coil 520 outputs current evenly to the outside.

[0056] Meanwhile, the fixed bracket 600 has limiting protrusions 610 extending towards the side plate 120 on its left and right sides respectively. These limiting protrusions 610 are located on the side of the rotating arm 220 away from the base plate 110. Therefore, the limiting protrusions 610 restrict the rotating arm 220 from rotating away from the base plate 110, allowing the rotating arm 220 to rotate within a set range. This ensures that the rocker arm 200 drives the magnetic component 400 to rotate within the effective range of the magnetic cavity 140. As can be seen from the above, the fixed bracket 600 precisely positions the iron core 510 and limits the movement range of the rotating arm 220, thereby ensuring that the magnetic component 400 moves within an effective range, thus guaranteeing stable power generation of the micro-generator module during operation.

[0057] To keep the fixing bracket 600 installed within the magnetic cavity 140, in one possible embodiment, the micro-generator module further includes a retainer 700 made of metal. The retainer 700 has two ends connected to the side plates 120. For example, each side plate 120 has a second snap-fit ​​hole 122, and the two ends of the retainer 700 are inserted into the second snap-fit ​​holes 122, thereby installing the retainer 700 between the two side plates 120. Simultaneously, along the front-rear direction of the magnetic cavity 140, the retainer 700 has sufficient width. Part of the retainer 700 is pressed against the side of the fixing bracket 600 away from the base plate 110 to keep the fixing bracket 600 installed within the magnetic cavity 140, while the other part is located on the side of the second magnetic sheet 430 away from the second magnetic sheet 430. Therefore, in practical applications, when the rocker arm 200 is in the first posture, the second magnetic sheet 430 contacts and connects with the retainer 700, thereby magnetically connecting with the metal casing 100. At this time, the first magnetic sheet 420 contacts and connects with the side of the iron core 510 near the base plate 110. When the rocker arm 200 is pressed to switch from the first posture to the second posture, the first magnetic sheet 420 contacts and connects with the base plate 110, and the second magnetic sheet 430 is separated from the retainer 700 and contacts and connects with the side of the iron core 510 away from the base plate 110. As can be seen from the above, through the setting of the retainer 700, the retainer not only serves to fix the fixed bracket 600 in the magnetic cavity 140, but the second magnetic sheet 430 can also magnetically connect with the metal casing 100 through the retainer 700, making the solution easier to implement.

[0058] In contrast to the aforementioned retainer 700, in another possible embodiment, please refer to... Figure 6Both side plates 120 are provided with a third bent portion 125 that bends towards the magnetic cavity 140. Along the front-rear direction of the magnetic cavity 140, the third bent portion 125 has sufficient width. Part of the third bent portion 125 is pressed against the side of the fixing bracket 600 away from the base plate 110 to hold the fixing bracket 600 within the magnetic cavity 140, while the other part is located on the side of the second magnetic sheet 430 away from the second magnetic sheet 430. Therefore, in practical application, when the rocker arm 200 is in its first posture, the second magnetic sheet 430 contacts and connects with the retaining member 700, thereby achieving magnetic connection with the metal casing 100. At this time, the first magnetic sheet 420 contacts and connects with the side of the iron core 510 near the base plate 110. When the rocker arm 200 is pressed to switch from the first posture to the second posture, the first magnetic sheet 420 contacts and connects with the base plate 110, while the second magnetic sheet 430 is separated from the third bend 125 and contacts and connects with the side of the iron core 510 away from the base plate 110. As can be seen from the above, through the setting of the third bend 125, the retainer, in addition to being used to fix the fixed bracket 600 in the magnetic cavity 140, allows the second magnetic sheet 430 to be magnetically connected to the metal shell 100 through the third bend 125, making the solution easier to implement.

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

[0060] In some embodiments, please refer to Figure 2 and Figure 3 The base plate 110 has an end plate portion 130 at its front end. One end of the iron core 510 is connected to the end plate portion 130, and the other end extends between the first magnetic sheet 420 and the second magnetic sheet 430, so as to be able to contact and connect with the first magnetic sheet 420 and the second magnetic sheet 430. The top of the fixing bracket 600 has a protruding edge 640. The coil 520 abuts between the end plate portion 130 and the protruding edge 640 of the fixing bracket 600. The side of the protruding edge 640 away from the coil 520 abuts against the side of the retainer 700 or the third bending portion 125. With this arrangement, the coil 520 and the fixing bracket 600 are compactly and securely installed in the magnetic cavity 140, and assembly is relatively convenient.

[0061] In some embodiments, the end plate portion 130 is provided with a second positioning hole, and the first positioning hole 630 is aligned with the second positioning hole. One end of the iron core 510 is inserted into the first positioning hole 630, and the other end of the iron core 510 extends toward the magnetic assembly 400. With this configuration, the iron core 510 is conveniently installed in the magnetic cavity 140 via the end plate portion 130. It is understood that the iron core 510 and the metal shell 100 are two independent components. With this configuration, the iron core 510 can be accurately installed in the magnetic cavity 140, thereby enabling the coil 520 sleeved on the outside of the iron core 510 to cooperate with the magnetic assembly 400. Thus, as the magnetic assembly 400 rotates with the magnetic chamber 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 portion 130, and the other end of the iron core 510 extends toward the magnetic component 400. This configuration allows the iron core 510 to be conveniently installed within the magnetic cavity 140 via the end plate portion 130. It is understood that the iron core 510 and the metal casing 100 are integrally integrated; the iron core 510 is also fabricated during the manufacturing process of the metal casing 100, eliminating the need for separate fabrication of the iron core 510 and saving costs.

[0063] In some embodiments, please also refer to Figure 5 The base plate 110 is provided with a clearance opening 112 for making way for the magnetic housing 210. It can be understood that by providing the clearance opening 112, the magnetic housing 210 can be moved aside during the pressing process, allowing the second magnetic sheet 430 to contact and connect with the base plate 110, and increasing the contact area between the second magnetic sheet 430 and the iron core 510, thereby improving the magnetic exchange efficiency and thus increasing the module's power generation and stability.

[0064] Secondly, please refer to Figures 1 to 3 This application provides an electrical product, including a product body and the aforementioned micro-generator module. The side wall of the front end of the side plate 120 is provided with a first snap-fit ​​hole 121, which is used for snap-fit ​​connection with the product body. The product body can be an electronic lock, without a power switch, etc. It is understood that when the micro-generator module is applied to the product body, it can be conveniently installed into the product body using the first snap-fit ​​hole 121. The micro-generator module of this application is relatively convenient to use and is used to supply power to the product body.

[0065] It is understandable that when the electrical product uses the aforementioned micro-generator module, and the micro-generator module needs to supply power to the product body, the user can overcome the elastic force of the elastic element 300 by pushing the rocker arm 200 to rotate through the magnetic chamber 210 or the power storage arm 230, so that the rocker arm 200 switches from the first posture to the second posture. When the user releases the magnetic chamber 210, the rocker arm 200 switches from the second posture to the first posture under the action of the elastic element 300. In this way, the rocker arm 200 switches back and forth between the first posture and the second posture. When the rocker arm 200 is held in its first position by the elastic member 300, the first magnetic plate 420 is in contact with the iron core 510, and the second magnetic plate 430 is in contact with the metal shell 100. When the user pushes the magnetic chamber 210, the magnetic chamber 210 overcomes the elastic force of the elastic member 300, and the first magnetic plate 420 is in contact with the metal shell 100, and the second magnetic plate 430 is in contact with the iron core 510. In this way, the magnetic component 400 moves relative to the coil, thereby causing the coil to cut magnetic field lines and generate current.

[0066] It is understandable that the micro-generator module adopts the above-mentioned structural form, that is, it uses a metal shell 100 to form a magnetic cavity 140, and the rocker arm 200, elastic element 300, magnetic component 400 and electromagnetic coil component 500 are all set in the magnetic cavity 140. The rocker arm 200 is connected to the elastic element 300 through a rearwardly extending storage arm 230. This arrangement can effectively reduce the contact angle between the first magnetic sheet 420, the second magnetic sheet 430 and the iron core 510 and the metal shell 100, thereby increasing the contact area between the first magnetic sheet 420, the second magnetic sheet 430 and the iron core 510 and the metal shell 100, and thus improving the magnetic force exchange efficiency. As a result, the power generation and stability of the micro-generator module are effectively guaranteed, and thus it can provide sufficient and stable power to the product body for product use.
