[0021] The utility model provides a kind of miniaturized intelligent actuator, to make the purpose, technical scheme and effect of the utility model more clear, definite, the following with reference to drawing and example of implementation are further detailed to the utility model.

[0022] In the description of the utility model, it needs to be understood that the orientation or positional relationship indicated by terms such as "up and down, left and right" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and cannot be understood as a limitation on the utility model; in addition, terms such as "mounting", "connecting" and the like should be broadly understood, and for ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0023] Please refer to Figure 1 And Figure 2 The utility model provides a kind of miniaturized intelligent actuator, including control chip 1, conductive via 2, iron core 3 and coil 4, the side of the iron core 3 is provided with the control chip 1, the edge of the control chip 1 is provided with a plurality of the conductive via 2 in row, coil 4 is fixed on the iron core 3 and the terminal of the coil 4 is respectively threaded in the conductive via 2 and is welded fixed.

[0024] In detail, the conductive via 2 includes positive power supply conductive hole and negative power supply conductive hole, the positive power supply conductive hole and negative power supply conductive hole are respectively arranged on the opposite sides of the control chip 1, the positive terminal of the coil 4 is welded in the positive power supply conductive hole, and the negative terminal is welded in the negative power supply conductive hole, that is, the positive power supply conductive hole and the negative power supply conductive hole are respectively arranged on the opposite sides, which simplifies circuit connection, reduces failure rate and improves the reliability of the actuator. More specifically, the positive power supply conductive hole and the negative power supply conductive hole are symmetrically arranged along the center line of the control chip 1.

[0025] Optionally, the positive and negative terminals of the coil 4 are carefully arranged on the left and right sides of the iron core 3, not only optimizing the space utilization, but also enhancing the stability and efficiency of the electrical connection. At the same time, the length of the control chip 1 is designed to be comparable to the thickness of the iron core 3, and such size matching enables the control chip 1 and the iron core 3 to be closely combined when the control chip 1 is installed on the iron core 3, forming a flat overall surface. This flat surface design has multiple advantages. First of all, it avoids any protruding structure, thereby significantly reducing the risk of damage due to bumps during daily use or transportation. Secondly, the flat surface is conducive to improving the heat dissipation performance, as heat can be more evenly distributed across the surface rather than concentrated in a certain point, which is crucial for maintaining the stable operation of electronic devices. In addition, this design also simplifies the manufacturing process, as there is no need for additional processing steps to smooth the surface or adjust the component positions.

[0026] In this embodiment, the conductive via 2 is in the shape of a U, and the U-shaped opening of the conductive via 2 is outwardly arranged at the edge of the control chip 1. The terminals of the coil 4 are clamped into the conductive via 2 from the U-shaped opening and fixed. The outwardly arranged conductive via 2 allows the terminals of the coil 4 to be conveniently clamped into the conductive via 2 from the U-shaped opening and fixed, ensuring good contact between the coil 4 and the conductive via 2 and simplifying the assembly process.

[0027] To reduce the number of external connections and lower the complexity and cost of the system, electronic components 5 are soldered on the control chip 1. It can be understood that the electronic components 5 are used to achieve precise control and protection functions for the actuator, and are directly soldered on the control chip 1. Specifically, these electrical components include capacitors, resistors, and inductors, etc. They play an important role in the control system, providing necessary circuit characteristics and functions. For example, capacitors can store and release electrical energy when needed, resistors can limit current and provide voltage division, and inductors can store magnetic field energy and release it when needed.

[0028] In summary, the miniaturized intelligent actuator of the present application arranges the conductive via 2, which serves as the connection point between the control chip 1 and the coil 4, on the outer edge of the control chip 1. By utilizing the edge position, there is no need to design a separate conductive via 2 in the control chip 1, which can reduce the overall volume, making the actuator more compact and portable, and facilitating installation and carrying. At the same time, it is not necessary to set aside the internal wiring position of the circuit board for setting, the terminals of the coil 4 correspond one-to-one with the conductive vias 2 at the edge of the control chip 1, and the coil 4 terminals can be directly clamped and soldered on the control chip 1. Welding from the outside of the control chip 1 has the advantage of simple welding. Therefore, the present application effectively overcomes the shortcomings of the prior art and has high industrial utilization value.

[0029] It can be understood that, for those skilled in the art, equivalent replacement or change can be made according to the technical scheme and the utility model concept of the utility model, and all these changes or replacements shall belong to the protection scope of the utility model.
