[0022] Reference Figs. 1-2 The embodiments of the intelligent voltage regulator of this utility model are further described below.

[0023] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0024] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0025] A smart voltage regulator includes a housing 1. Input terminals 2 and output terminals 3 are located on the left and right sides of the housing 1. An installation cavity 4 is located inside the housing 1. A voltage regulating module, a smart control module, and a voltage detection module 9 are housed inside the installation cavity 4. The voltage regulating module is arranged sequentially from front to back within the installation cavity 4. Each voltage regulating module includes a voltage regulating circuit 5 and a power device 6. A heat dissipation structure is also provided within the voltage regulating module. By adopting the above technical solution, the smart voltage regulator has input terminals 2 and output terminals 3 on the outside of the housing. The voltage regulating module, smart control module, and voltage detection module 9 are arranged sequentially from front to back inside the installation cavity 4. This arrangement is compact and easy to adjust. The voltage regulating module also has a heat dissipation mechanism, specifically a heat sink 10 and a temperature-controlled fan on its surface. The fan 11 and the heat sink 10 are located adjacent to each other, which helps to improve heat conduction efficiency. The temperature control fan 11 is controlled by an intelligent control module. The intelligent controller can adjust the speed of the temperature control fan 11 according to the signal transmitted by the temperature sensor 17. The heat sink 10 has a multi-fin structure, and the heat flow direction of the heat sink 10 is parallel to the airflow direction of the temperature control fan 11. The side of the housing 1 is provided with ventilation holes 12. The multi-fin structure of the heat sink 10 can effectively enhance the heat conduction performance of the heat sink 10 and improve the heat dissipation effect. The heat sink 10, the temperature control fan 11 and the ventilation holes 12 on the housing are at the same height, which helps to improve the overall heat dissipation efficiency of the heat dissipation mechanism. Furthermore, thermal grease is applied between the voltage regulating circuit 5 and the heat sink 10, which can effectively transfer heat from the voltage regulating circuit 5 to the heat sink 10, further improving the heat dissipation effect.

[0026] Furthermore, the voltage regulation circuit 5 on the voltage regulation module is driven by a pulse width modulation (PWM) signal. This driving method is in digital form during signal transmission, with low noise. Moreover, this driving method is relatively mature. By adopting the above technical solution, the actual application cost is low and the control effect is good.

[0027] The intelligent voltage regulator of the present invention further includes a display module, which includes a display screen 13 and a button 14 disposed on the front surface of the housing 1. The display screen 13 and the button 14 are both connected to the intelligent control module through ribbon cables. The display screen 13 is used to reflect the input and output voltage levels, and the button 14 can turn the voltage regulation function on or off. Other functions can also be added according to the actual situation. This module can more intuitively reflect the status of the voltage regulator to the user and ensure the necessary human-machine interaction performance.

[0028] The bottom of the mounting cavity 4 is equipped with a protection module, which includes an overvoltage protection circuit 15, an overcurrent protection circuit 16, and a temperature sensor 17, and is electrically connected to the voltage regulation module and the intelligent control module. By adopting the above technical solution, the overvoltage and overcurrent protection circuits 16 on the protection module can monitor and protect against voltage and current. The temperature sensor 17 can monitor the real-time temperature and transmit the real-time temperature information to the intelligent control module, and adjust the speed of the temperature-controlled fan 11. Furthermore, both the overvoltage protection circuit 15 and the overcurrent protection circuit 16 adopt a combination structure of a fast-acting fuse and a relay, and are connected in series with the output terminal 3. The fast-acting fuse has high sensitivity; once the circuit current is overloaded, the fuse wire inside the fast-acting fuse will quickly heat up and melt, providing further protection to the circuit. The relay is used to assist the protection circuit, providing overvoltage, undervoltage, and zero-voltage protection. Fast-acting fuses and relays are commonly used in automated control circuits, and the new voltage regulator introduced in this paper is no exception; these two protective devices are also quite important in control components.

[0029] Furthermore, the outer shell 1 is made of flame-retardant ABS plastic, and the surface of the internal circuit board is coated with a conformal coating. The flame-retardant ABS plastic not only has good heat resistance, but also high hardness and corrosion resistance, with good overall performance and low cost. The conformal coating can withstand both high and low temperatures. After curing, it forms a transparent protective film with a series of superior properties such as insulation, moisture resistance, shock resistance, dust resistance, and anti-aging. As a coating, it is relatively reliable and has a strong protective ability for the circuit board. The manufacturing materials and coating materials mentioned above can also be replaced according to actual needs. It is not necessary to stick to the same material as long as it meets the requirements.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
