When not in use, they are not only easily affected by the external environment, but also protrude from the radio body during carrying or storage, taking up a lot of space and easily scratching other items, causing damage to the equipment or affecting the storage of other items. Therefore, a manual power generation structure for emergency radios is proposed to solve the above problems. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6This utility model provides an embodiment of a manual power generation structure for an emergency radio, comprising a radio body 1, which serves as the core of the entire device, accommodating and supporting other components. A solar panel 2 is installed inside the radio body 1, converting solar energy into electrical energy to provide additional power to the radio. A signal rod 3 is installed on the side wall of the radio body 1, used to receive broadcast signals. By adjusting its angle and length, the signal reception effect of the radio can be optimized. A gear 6 is rotatably connected inside the radio body 1, serving as a transmission component. This gear 6 transmits the manual rotational force from the rotating plate 12 to a meshing gear 9, changing the direction and speed of force transmission, making manual power generation more efficient and stable. Gear 9 is rotatably connected inside the radio body 1, and a fixing frame 7 is fixedly connected inside the radio body 1. The fixing frame 7 is used to fix the generator 8, ensuring the stability of the generator 8 during operation and preventing it from being affected by shaking or displacement, thus extending its power generation efficiency and service life. A generator 8 is fixedly connected inside the mounting frame 7. The generator 8 is a key component that converts mechanical energy into electrical energy. By manually turning the handle 13, the rotor of the generator 8 is driven to rotate via gear transmission, generating electrical energy and storing it in the storage battery 10 to provide power for the radio and other related functions. The storage battery 10 is installed inside the radio body 1. The storage battery 10 is used to store the electrical energy generated by the generator 8 and the electrical energy converted by the solar panel 2, so as to power the various functional modules of the radio when needed. A rotating shaft 11 is rotatably connected inside the radio body 1. The rotating shaft 11 provides a rotation support point for the rotating plate 12, allowing the rotating plate 12 to rotate flexibly around its axis, thereby driving the handle 13 to perform manual power generation. The rotating plate 12 is rotatably connected inside the rotating shaft 11. The handle 13 is fixedly connected to the side wall of the rotating plate 12. The handle 13 makes it easier for the user to apply force, making the rotating plate 12 rotate more easily and improving the efficiency and convenience of manual power generation. A fixing component is provided on the lower surface of the radio body 1. The fixing component is used to fix the rotating plate 12 inside the radio body 1 when the handle 13 is not used, so as to prevent it from shaking randomly. A telescopic component is provided on the side wall of the radio body 1. The fixing component includes a fixing plate 15. The fixing plate 15 serves as the basic support part of the fixing component. Its side wall is fixedly connected to the lower surface of the radio body 1, providing a stable installation position for the rotating shaft 16 and other related components.A rotating shaft 16 is fixedly connected inside the fixed plate 15. A locking block 17 is rotatably connected to the side wall of the rotating shaft 16. Under the action of the spring 19, the locking block 17 can rotate around the rotating shaft 16. When the fixing rod 14 is inserted between the locking blocks 17, the locking block 17 can lock the fixing rod 14, thereby fixing the position of the rotating plate 12. A fixing block 18 is fixedly connected to the side wall of the locking block 17. The fixing block 18 is connected to the spring 19 and is used to transmit the elastic force of the spring 19. The spring 19 is fixedly connected to the upper surface of the fixed plate 15, and the spring 19 provides the locking block 17 with The elasticity allows it to automatically reset and maintain the clamping force on the fixed rod 14. The fixed rod 14 is fixedly connected to the side wall of the rotating plate 12. The upper surface of the rotating shaft 11 is fixedly connected to the lower surface of the gear 6, ensuring that the rotating plate 12 can accurately transmit power to the gear 6 when it rotates. The gear 6 meshes with the gear 9. This meshing relationship can effectively transmit power, converting the rotation of the gear 6 into the rotation of the gear 9. The speed and torque can be changed according to the gear ratio, so that the generator 8 can generate electricity efficiently at a suitable speed. The radio body 1 has an interface 4 inside, which can be used to connect external devices, such as headphones and chargers, to expand the radio's functions. The radio body 1 also has a light 5 inside, which can provide illumination for the user in emergencies, making it easier for the user to see the surrounding environment and find items in the dark, increasing the practicality and functionality of the emergency radio.
[0037] When using this device for manual power generation, the handle 13 is rotated by hand. The handle 13 serves as the point of manual force application, allowing the user to grip and apply torque, thereby rotating the fixedly connected rotating plate 12. The rotating plate 12 transmits power, converting the rotation of the handle 13 into the rotation of the rotating shaft 11, which in turn drives the gear 6. Gear 6, as an intermediate link in the power transmission, effectively transmits and changes the speed of the power from the rotating plate 12 through its meshing with gear 9, thus driving gear 9 to rotate. The rotation of gear 9, in turn, drives the generator 8. The generator 8 is a key component that converts mechanical energy into electrical energy, and the electrical energy generated by its rotation is supplied to the battery 10. The battery 10, as an electrical energy storage device, stores the electrical energy generated by the generator 8, providing power support for devices such as radios when needed, thus achieving manual power generation and providing a reliable energy guarantee for the radio in the absence of an external power source. When not in use, the rotating plate 12 can be rotated to change the position of the handle 13, allowing it to slide into the radio body 1. During this rotation, the fixing rod 14 contacts the locking block 17. The fixing rod 14, as a component connecting the rotating plate 12 and the locking block 17, serves to position and fix the handle. When the fixing rod 14 contacts the locking block 17, it compresses it, causing the spring 19 to contract. As an elastic element, the spring 19 can store elastic potential energy when compressed and release it after the compression force disappears, returning to its original shape. During the compression and contraction of the spring 19, the locking block 17 rotates. The rotation of the locking block 17 changes its relative position with the fixing rod 14, allowing the fixing rod 14 to slide into the locking block 17, achieving a fixing effect and thus hiding the handle 13. Hiding the handle 13 effectively prevents it from being bumped or damaged during the carrying or storage of the radio, while also making the radio's appearance cleaner and reducing the inconvenience that might be caused by the exposed handle 13.
[0038] Reference Figure 5 and Figure 7The telescopic assembly includes a second fixing block 20, which provides a stable support point for the tension band 21. A mounting sleeve 22 is fixedly connected to the side wall of the radio body 1. The mounting sleeve 22 accommodates and fixes a second fixing plate 23 and related connecting components. A tension band 21 is fixedly connected to the side wall of the second fixing block 20. The tension band 21 is a key component for achieving the telescopic function; it has good flexibility and stretchability, allowing its length to be flexibly changed as needed. A second fixing plate 23 is fixedly connected inside the mounting sleeve 22. The second fixing plate 23 serves as a support structure inside the mounting sleeve 22, used to fix components such as the connecting rod 24 and the rotating column 25. A connecting rod 24 is rotatably connected inside the second fixing plate 23, connecting the tension band 21 and the rotating column 25. The tension band 21... The wall is slidably connected inside the mounting sleeve 22. This sliding connection allows the tension band 21 to move smoothly along the inner wall of the mounting sleeve 22 during extension and retraction. The side wall of the tension band 21 is fixedly connected to the side wall of the connecting rod 24, ensuring a tight connection between the tension band 21 and the connecting rod 24. This allows the tension band 21 to effectively drive the connecting rod 24 to rotate during extension and retraction. The fixing plate 23 has a rotating column 25 rotatably connected inside. The rotating column 25 serves as the connection hub between the connecting rod 24 and the tension spring 26. It can rotate around its connection point with the fixing plate 23 under the drive of the connecting rod 24. At the same time, it transmits the elastic force of the tension spring 26 to the connecting rod 24, providing elastic restoring force for the extension and retraction of the tension band 21. This allows the tension band 21 to automatically return to its initial position after extension, realizing the automatic reset of the extension and retraction function. The lower surface of the rotating column 25 is fixedly connected to the upper surface of the connecting rod 24, ensuring a rigid connection between the rotating column 25 and the connecting rod 24, enabling them to move synchronously. A tension spring 26 is fixedly connected to the side wall of the rotating column 25. The tension spring 26 can generate elastic deformation when the tension band 21 is stretched, storing elastic potential energy. When the tension force disappears, the tension spring 26 releases the elastic potential energy, driving the rotating column 25 to rotate, thereby causing the connecting rod 24 and the tension band 21 to return to their initial positions, realizing the automatic retraction function of the telescopic assembly. A fixing column 27 is fixedly connected to the upper surface of the fixing plate 23. The fixing column 27 is used to fix one end of the tension spring 26, providing a stable mounting point for the tension spring 26, limiting the displacement of the tension spring 26, and ensuring that the tension spring 26 can generate elastic deformation in a predetermined direction during the telescopic process, thereby ensuring that the tension spring 26 can stably exert the elastic restoring force and ensuring the normal operation of the telescopic assembly. The side wall of the tension spring 26 is fixedly connected to the side wall of the fixing column 27, so that the tension spring 26 can be firmly fixed on the fixing plate 23.
[0039] Before manually generating electricity using the device, the tension belt 21 can be pulled. The tension belt 21 has good flexibility and stretchability, allowing its length to be flexibly changed according to the user's pulling action. This allows the user to adjust the distance between the belt and their body according to their needs, better adapting to different usage scenarios and individual body sizes, and facilitating the subsequent fixing of the radio body 1 in a suitable position. Pulling the tension belt 21 causes the connecting rod 24 to rotate. As a key component connecting the tension belt 21 and the rotating column 25, the connecting rod 24 converts the tension of the tension belt 21 into its own rotational torque, thereby achieving force transmission and motion conversion, ensuring that the pulling action of the tension belt 21 effectively drives the rotating column 25 to rotate. The rotation of the connecting rod 24 drives the rotating column 25 to rotate. As the core transmission component of the entire telescopic assembly, the rotation of the rotating column 25 changes the state of the tension spring 26 and provides stable support and guidance for the extension and retraction of the tension spring 26, ensuring that the tension spring 26 can deform along a predetermined direction during extension and retraction, thereby storing and releasing elastic potential energy. The rotation of the rotating column 25 causes the tension spring 26 to contract. As an elastic element, the tension spring 26 stores elastic potential energy when it contracts under the influence of the rotating column 25, providing power for the subsequent rebound. This mechanism of storing and releasing elastic potential energy enables the telescopic component to achieve automatic reset and fit, increasing ease of use and comfort. The radio body 1 is then placed in a suitable position, such as on the hand, arm, or other body part. As the core of the entire device, the radio body 1 houses various electronic components and mechanical parts. Placing it on the body helps maintain stability during manual power generation, reducing the impact of shaking on power generation and reception. It also allows the user to easily access information in emergencies. Then, the tension band 21 is released, causing the tension spring 26 to rebound. The rebound of the tension spring 26 releases the previously stored elastic potential energy, converting it into kinetic energy, driving the rotating column 25 to rotate in the opposite direction. This, in turn, causes the connecting rod 24 and the tension band 21 to return to their initial positions or to fit the user's contact area. The tension strap 21 is attached to the user's contact area. The attachment of the tension strap 21 can form a relatively stable connection between the radio body 1 and the body part, preventing the radio from falling or shifting due to shaking or vibration during use, thus ensuring the safety and reliability of the equipment. At the same time, it allows the hands to operate the generator handle more freely without having to be distracted by fixing the radio, improving the convenience and efficiency of operation.
[0040] Working principle: When using this device for manual power generation, the handle 13 is rotated, which in turn rotates the rotating plate 12. This causes the rotating shaft 11 to drive the gear 6, which in turn drives the gear 9, thereby rotating the generator 8. The electrical energy generated by the generator 8 is supplied to the battery 10, thus achieving manual power generation. When not in use, the rotating plate 12 can be rotated to slide the handle 13 into the radio body 1. During rotation, the fixing rod 14 contacts the locking block 17 and is compressed, causing the spring 19 to contract and rotate. The fixing rod 14 slides into the locking block 17 to achieve a fixing effect, thereby hiding the handle 13. Before using the device to generate electricity manually, the connecting rod 24 can be rotated by pulling the tension band 21. The rotation of the connecting rod 24 drives the rotating column 25 to rotate. The rotation of the rotating column 25 will cause the tension spring 26 to contract. Then, place the radio body 1 in a suitable position, such as the hand, arm or other body part. Then release the tension band 21 to make the tension spring 26 rebound, so that the tension band 21 fits against the user's contact area, allowing the hands to operate the generator handle more freely without worrying about the radio falling or shifting.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
