Description
Technical Field
[0001] This utility model relates to the field of high-frequency inductor technology, specifically to an improved high-frequency inductor. Background Technology
[0002] In fields such as power electronics and communication equipment, high-frequency inductors are key components, and their performance affects the overall operating efficiency. Currently, the industry's structural design of high-frequency inductors mainly focuses on optimizing internal performance, such as improving core materials, improving winding structure, and enhancing shielding design, in order to reduce high-frequency losses, broaden the frequency range, and optimize parasitic parameters. The related technical system is relatively mature. However, the installation adaptability and external protection design of high-frequency inductors have long been neglected, becoming a bottleneck restricting their reliability. Current mainstream products have obvious defects: most adopt exposed installation, making core components susceptible to damage from collisions and friction; some adopt fully encapsulated packaging, which improves protection but blocks the heat dissipation path, causing the inductor to operate at high temperatures, resulting in performance degradation, shortened lifespan, and inability to meet the needs of high power density scenarios. To resolve the conflict between protection and heat dissipation, some related technologies have been attempted, such as a novel high-frequency inductor described in Chinese patent CN 222462523 U, which combines a closed protective cabinet with water cooling. However, this solution does not include a coolant cooling circulation structure. After long-term operation, the coolant temperature rises, and the heat dissipation efficiency drops sharply, still failing to meet the long-term stable operation requirements of high-frequency inductors. In summary, the current lack of technical solutions that combine protection and efficient heat dissipation necessitates innovative design to overcome the bottleneck. Utility Model Content
[0003] In view of the shortcomings of the prior art, this utility model provides an improved high-frequency inductor, which solves the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an improved high-frequency inductor, comprising a high-frequency inductor body; Mounting plates are detachably mounted on the top and bottom of the high-frequency inductor body by bolts. Multiple rotating shafts are rotatably connected between the opposite sides of the two mounting plates, and a cover plate is fixedly mounted on the outside of any one of the rotating shafts. The upper surface of the upper mounting plate is provided with a transmission assembly for driving multiple rotating shafts to rotate synchronously. The bottom of the lower mounting plate is equipped with a servo motor whose output end is connected to one of the rotating shafts. A temperature sensor electrically connected to the servo motor is also installed on the upper surface of the lower mounting plate.
[0005] Furthermore, the top projection of the mounting plate is a regular hexagon.
[0006] Furthermore, the number of the rotating shafts is six, and they are arranged in a circular array at the six corners of the mounting plate.
[0007] Furthermore, each of the cover plates is located on the side away from the corresponding pivot and is fitted to the outer side of the adjacent pivot.
[0008] Furthermore, a protective cover is provided on the upper surface of the upper mounting plate, and a support base is provided at the bottom of the lower mounting plate.
[0009] Furthermore, the top end of each of the shafts penetrates through the upper mounting plate and extends above the upper mounting plate.
[0010] Furthermore, the transmission assembly includes multiple gears and a gear ring; Multiple gears are correspondingly sleeved on the outer side of multiple rotating shafts, and the gear ring is rotatably connected to the upper surface of the upper mounting plate and meshes with the multiple gears.
[0011] Furthermore, the output end of the servo motor is connected to the corresponding rotating shaft via a coupling.
[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects: This improved high-frequency inductor achieves a dynamic balance between protection and heat dissipation through a synchronously opening and closing cover and temperature-linked control design. Under normal conditions, the cover is closed to form a sealed protection, preventing core components from being damaged. At high temperatures, the cover automatically opens to dissipate heat quickly, preventing the decrease in permeability, inductance drift, or aging of insulation materials caused by excessive temperature. This significantly improves the operational stability and service life of the high-frequency inductor, making it suitable for high-frequency and high-power-density operating conditions.

[0015] 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.
[0016] Please see Figure 1-4 This embodiment presents an improved high-frequency inductor, which is used to protect the high-frequency inductor and to dissipate heat when an internal temperature rise is detected. It mainly consists of a high-frequency inductor body 1, a mounting plate 2, a rotating shaft 3, a cover plate 4, a transmission assembly 5, a servo motor 6, a temperature sensor 7, a protective cover 8, and a support base 9.
[0017] Specifically, the top and bottom of the high-frequency inductor body 1 are detachably connected to mounting plates 2 by bolts. The top projection shape of the mounting plate 2 is a regular hexagon. Six rotating shafts 3 are rotatably connected between the opposite sides of the two mounting plates 2. The six rotating shafts 3 are arranged in a ring array at the six corners of the mounting plate 2 to ensure balanced force and cover the outer periphery of the high-frequency inductor body 1. A cover plate 4 is fixedly installed on the outside of any rotating shaft 3. The side of each cover plate 4 away from the corresponding rotating shaft 3 is in contact with the outside of the adjacent rotating shaft 3.
[0018] In actual setup, when the six cover plates 4 are closed simultaneously, they can completely surround the high-frequency inductor body 1, forming a complete physical protective layer; when the cover plates 4 are opened, they can provide an open heat dissipation space for the high-frequency inductor body 1.
[0019] In more detail, the upper surface of the upper mounting plate 2 is provided with a transmission assembly 5 for driving the six rotating shafts 3 to rotate synchronously. The transmission assembly 5 includes six gears 501 and a gear ring 502. The six gears 501 are respectively sleeved on the outer side of the six rotating shafts 3, and the top of each rotating shaft 3 passes through the upper mounting plate 2 and extends above it. The gears 501 are fixed to the extended part of the rotating shaft 3. The gear ring 502 is rotatably connected to the upper surface of the upper mounting plate 2 and meshes with all six gears 501. The gear ring drives the multiple gears to rotate synchronously, ensuring that the rotation angle of all rotating shafts 3 is consistent, thereby realizing the synchronous opening and closing of the cover plate 4.
[0020] A servo motor 6 is installed at the bottom of the lower mounting plate 2. The output end of the servo motor 6 is connected to one of the rotating shafts 3 via a coupling to provide a power source for the rotation of the rotating shaft 3. At the same time, a temperature sensor 7 electrically connected to the servo motor 6 is installed on the upper surface of the lower mounting plate 2. The temperature sensor 7 can detect the ambient temperature around the high-frequency inductor body 1 in real time and transmit the temperature signal to the control module of the servo motor 6 to realize temperature linkage control.
[0021] In addition, a protective cover 8 is provided on the upper surface of the upper mounting plate 2. The protective cover 8 can completely cover the transmission component 5 to prevent external dust and impurities from entering the meshing area of the gear 501 and the gear ring 502, and to prevent transmission jamming or component wear. A support base 9 is fixedly provided at the bottom of the lower mounting plate 2.
[0022] It should be noted that the electrical connection between the temperature sensor 7 and the servo motor 6 in this application is a prior art that has been disclosed. For details, please refer to the authorized Chinese patent announcement number: CN107863914B, A self-adjusting system for the rotor time constant of an asynchronous motor. This application mainly protects the mechanical structure, so the electrical control method between the temperature sensor 7 and the servo motor 6 will not be described in detail.
[0023] In actual use, during normal operation and protection, the servo motor 6 drives the corresponding rotating shaft 3 to rotate. The rotating shaft 3 drives the outer gear 501 to rotate. The gear 501 drives the gear ring 502 to rotate on the upper mounting plate 2. The gear ring 502 further drives the other five gears 501 to rotate synchronously. All rotating shafts 3 rotate in the same direction, eventually driving the six cover plates 4 to close synchronously. The side of the cover plate 4 away from the rotating shaft 3 is in contact with the adjacent rotating shaft 3, forming a closed protective layer around the high-frequency inductor body 1 to prevent external collisions and friction from damaging the core components. In high-temperature heat dissipation scenarios, when the high-frequency inductor body 1 generates a large amount of heat under high-frequency operating conditions, the temperature sensor 7 detects that the ambient temperature exceeds the preset threshold and sends a signal to the servo motor 6. The servo motor 6 rotates in the opposite direction, and through the transmission component 5, it drives all the rotating shafts 3 to rotate in the opposite direction. The six cover plates 4 open synchronously, and the high-frequency inductor body 1 comes into direct contact with the outside air, and the heat is quickly dissipated until the temperature drops to a safe range. Then, the servo motor 6 drives the cover plates 4 to close again.
[0024] The working principle of the above embodiments is as follows: (1) When the high-frequency inductor is in normal operation and the temperature does not exceed the threshold, the equipment enters the normal protection mode. The operator starts the servo motor 6 through the external control command. The output end of the servo motor 6 drives the shaft 3 connected to it to rotate clockwise through the coupling. The part of the shaft 3 extending to the upper side mounting plate 2 is fitted with a gear 501. When the shaft 3 rotates, it drives the gear 501 to rotate clockwise. Since the gear 501 meshes with the gear ring 502, the rotation of the gear 501 drives the gear ring 502 to rotate clockwise on the upper surface of the upper side mounting plate 2. The gear ring 502 further meshes with the gears 501 of the other five shafts 3, driving all the gears 501 to rotate clockwise synchronously, thereby making the six shafts 3 rotate in the same direction. The cover plate 4 fixed on the outside of the shaft 3 rotates synchronously with the shaft 3. Since the side of each cover plate 4 away from the shaft 3 is in contact with the adjacent shaft 3, when the shaft 3 rotates to the preset angle, the six cover plates 4 are completely closed, forming a closed protective layer around the high-frequency inductor body 1.
[0025] (2) When the high-frequency inductor operates under high frequency and high power conditions, the winding and magnetic core generate a lot of heat, causing the ambient temperature to rise. The equipment automatically switches to high temperature heat dissipation mode. At the same time, the temperature sensor 7 on the upper surface of the lower mounting plate 2 detects the ambient temperature in real time. When the temperature exceeds the preset safety threshold, the temperature sensor 7 converts the temperature signal into an electrical signal and transmits it to the control module of the servo motor 6. After receiving the signal, the output end of the servo motor 6 rotates in the opposite direction and drives the corresponding shaft 3 to rotate counterclockwise through the coupling. The gear 501 of the shaft 3 rotates counterclockwise, driving the gear ring 502 to rotate counterclockwise, thereby driving all gears 501 to rotate counterclockwise synchronously with the shaft 3. The shaft 3 drives the cover plate 4 to rotate counterclockwise synchronously. The six cover plates 4 gradually open, and the outer periphery of the high-frequency inductor body 1 is directly exposed to the air. The heat is quickly dissipated to the outside through convection and radiation.
