DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1 、 Figure 2 and Figure 4, the utility model provides an embodiment: a power adapter with heat dissipation and anti-fall functions, including a shell 1, a protective box 2 is fixedly connected to the inside of the shell 1, the shell 1 provides good protection for the internal electronic components, and the protective box 2 provides an additional layer of protection for the adapter body 3 to prevent it from being damaged when it is hit or dropped. The outside of the protective box 2 is fixedly connected to a fixed box 23 on both sides, and the fixed box 23 is used to support and fix the slide bar 8. The inside of the two fixed boxes 23 is fixedly connected to the slide bar 8, and the slide bar 8 provides a linear sliding track for the slider 7. The outside of the two slide bars 8 is slidably connected to the slider 7. The slider 7 can slide freely on the slide bar 8, providing a fulcrum for the movable support rod 6 and the protective plate 5. One side of the multiple sliders 7 is rotatably connected to the movable support rod 6 One end of the protective box 2, the other ends of the multiple movable support rods 6 are rotatably connected to the protective plate 5, the outer sleeve of the sliding rod 8 is provided with a buffer spring 9, the buffer spring 9 can absorb and disperse the impact force, and reduce the direct impact on the adapter body 3, the outer sides of the protective box 2 are fixedly connected with fixed rods 10, the inner parts of the multiple fixed rods 10 are slidably connected with moving rods 11, the other ends of the multiple moving rods 11 are fixedly connected to the protective plate 5, both ends of the buffer spring 9 are fixedly connected to the slider 7, the outer parts of the multiple fixed rods 10 and the moving rods 11 are provided with a compression spring 12, the compression spring 12 can provide additional buffering and support when the moving rod 11 and the fixed rod 10 are subjected to external force, one end of the compression spring 12 is fixedly connected to the protective box 2, and the other end of the compression spring 12 is fixedly connected to the protective plate 5.

[0025] Safely placing the adapter body 3 into the protective box 2 can provide all-round protection for the adapter body 3. During the use of the adapter body 3, due to various unpredictable situations, the two protective plates 5 may be hit by external forces, or when the entire housing 1 accidentally falls, the protective plates 5 will play a vital role. At this time, the two protective plates 5 will squeeze the movable support rod 6. This design enables the movable support rod 6 to drive the slider 7 to slide along the outside of the slide rod 8 when it is squeezed. When the two sliders 7 slide on the slide rod 8, they will squeeze the buffer spring 9, and the buffer spring 9 will be squeezed. After being pressed, it can effectively play a buffering role, absorb and disperse external forces, and reduce direct impacts on the adapter body 3. In addition, when the protective plates 5 are hit, they will also squeeze the moving rod 11. After being squeezed, the moving rod 11 will slide toward the inside of the fixed rod 10. This action further increases the stability and protection capabilities of the entire system. At the same time, the movement of the protective plate 5 will also squeeze the compression spring 12. The intervention of the compression spring 12 provides a secondary buffer for the system, which means that after the first buffer, there is still an extra layer of protection to further reduce the impact of external shocks on the adapter body 3.

[0026] Reference Figure 3 and Figure 5The inside of the shell 1 is fixedly connected to a cylinder 13, and the output end of the cylinder 13 is fixedly connected to a push block 14. The upper part of the push block 14 is fixedly connected to a heat dissipation component, and the heat dissipation component is used to dissipate heat for the adapter body 3. The inner sides of the shell 1 are fixedly connected to limit rods 20, and the limit rods 20 play a role in guiding and limiting the range of movement of the components. The bottom of the push block 14 is fixedly connected to a limit block 19, and the limit block 19 is slidably connected to the outside of the limit rod 20. Ventilation holes 22 are provided at the bottom of the shell 1. The ventilation holes 22 help air flow and further help the heat dissipated by the heat dissipation component to dissipate to the outside. The heat dissipation component includes a fixed frame 15, which is fixedly connected to the upper part of the push block 14. The inside of the fixed frame 15 is fixedly connected to a motor 16, and the output end of the motor 16 is fixedly connected to a turntable 17. The turntable 1 The outside of 7 is fixedly connected with fan blades 18 on all sides. When the fan blades 18 rotate, airflow is generated to effectively take away the heat from the adapter body 3. The adapter body 3 is arranged inside the protective box 2. The protective box 2 provides additional protection and support for the adapter body 3. Cables 4 are fixedly connected on both sides of the adapter body 3. Cables 4 are used to connect the power adapter to an external power supply or device. The two cables 4 are inserted into the inside of the protective box 2. Two protective plates 5 are arranged on both sides of the outer shell 1. The protective plates 5 can provide protection when the adapter is hit. A reset spring 21 is provided on the outer sleeve of the limit rod 20. One end of the reset spring 21 is fixedly connected to the inside of the outer shell 1, and the other end of the reset spring 21 is fixedly connected to the limit block 19. The reset spring 21 can provide a reaction force to help the limit block 19 return to its initial position.

[0027] When the cylinder 13 is activated, its output end will apply force to push the push block 14, and the push block 14 will start to move after receiving the pushing force. During the movement, the push block 14 will drive the limit block 19, and the limit block 19 is designed to be able to slide on the outside of the limit rod 20. This sliding mechanism ensures the precise movement of the limit block 19. When the limit block 19 slides, it will come into contact with the return spring 21 and squeeze or stretch it. The design of the return spring 21 enables it to play a buffering role when it is squeezed or stretched, thereby reducing the impact force on the limit block 19 and protecting the entire system from damage. Under the guidance of the limit block 19, the push block 14 will continue to move and drive the fixed frame 15. The movement of the fixed frame 15 is A key link in the design, because it is connected to the motor 16, as the fixed frame 15 moves, the motor 16 will also move. This design allows the position of the motor 16 to be adjusted to adapt to different working requirements. The movement of the motor 16 will also drive the turntable 17 and the fan blades 18. These components are located at the lower part of the adapter body 3. They can move back and forth under the drive of the motor 16, which not only increases the air flow, but also improves the heat dissipation efficiency. When the motor 16 starts, its output end will drive the turntable 17 to rotate. When the turntable 17 rotates, it will further drive the fan blades 18 to rotate. The design of the fan blades 18 enables it to generate a strong airflow during the rotation process. This airflow effectively cools the adapter body 3.

[0028] Working principle: When in use, first put the adapter body 3 into the protective box 2. During the use of the adapter body 3, when the two protective plates 5 are hit or when the shell 1 falls, the two protective plates 5 squeeze the movable support rod 6. The movable support rod 6 is squeezed and drives the slider 7 to slide on the outside of the slide rod 8. When the two sliders 7 slide, they squeeze the buffer spring 9. The buffer spring 9 is squeezed and plays a certain buffering role. When the protective plate 5 is hit, it squeezes the moving rod 11. The moving rod 11 slides toward the inside of the fixed rod 10. The protective plate 5 moves to squeeze the compression spring 12. The compression spring 12 plays a secondary buffering role, which effectively protects the adapter body 3 and can better withstand falls and impacts in daily use, reduces damage caused by external impacts, and improves the overall durability of the adapter. Start the cylinder 13 The output end of the cylinder 13 pushes the push block 14 to move. When the push block 14 moves, it drives the limit block 19 to slide on the outside of the limit rod 20. When the limit block 19 slides, it squeezes or stretches the return spring 21, and the return spring 21 plays a buffering role on the limit block 19. Under the action of the limit block 19, the push block 14 drives the fixed frame 15 to move, and the fixed frame 15 moves to drive the motor 16 to move. The movement of the motor 16 drives the turntable 17 and the fan blades 18 to move back and forth at the lower part of the adapter body 3, and the motor 16 is started. The output end of the motor 16 drives the turntable 17 to rotate, and the turntable 17 drives the fan blades 18 to rotate. Under the action of the fan blades 18, the adapter body 3 is cooled and dissipated, which effectively drives the fan to move back and forth, increases air flow, and more effectively takes away the heat generated inside the adapter, thereby improving the heat dissipation efficiency and extending the service life of the power adapter.
