Description

Technical Field

[0001] This utility model relates to the field of servo driver technology, specifically a novel miniaturized intelligent servo driver. Background Technology

[0002] Miniaturized intelligent servo drives refer to highly integrated and compact servo drive systems, typically used to control the motion of electric motors, especially in applications requiring high precision, high response speed, and miniaturization. These drives not only possess the functions of traditional servo drives (such as adjusting motor speed, position, and torque), but also usually incorporate intelligent features, enabling them to autonomously control, diagnose, and optimize.

[0003] Currently, existing miniaturized intelligent servo drives typically have heat dissipation windows to allow the internal circuit board to communicate with the external environment. This reduces the risk of overheating of the internal circuit board during prolonged operation, which could decrease performance or cause damage. Some miniaturized intelligent servo drives incorporate cooling fans to further improve heat dissipation. These fans directly deliver outside air to the internal circuit board, improving its cooling efficiency. While this method improves heat dissipation, if the internal circuit board is large, two or more cooling fans are needed to cool different areas of the circuit board. The use of multiple cooling fans increases production costs.

[0004] Therefore, we propose a novel miniaturized intelligent servo driver to solve the above problems. Utility Model Content

[0010] Furthermore, the airflow guiding assembly includes two limiting plates fixedly disposed at the bottom of the inner side of the driver housing. The two limiting plates are symmetrical about the cooling fan. Multiple air guide plates are rotatably disposed between the two limiting plates.

Detailed Implementation

[0025] 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.

[0026] Example

[0027] like Figure 1-5 As shown in the figure, a novel miniaturized intelligent servo driver according to one embodiment of the present invention includes a driver housing 1. A support plate 2 is fixedly disposed on the lower end face of the driver housing 1. The cross-section of the support plate 2 is U-shaped. A cooling fan 3 is disposed on the lower end face of the support plate 2. The cooling fan 3 communicates with the driver housing 1. A circuit board 4 is disposed inside the driver housing 1. Heat dissipation windows 6 are opened at both ends of the driver housing 1. An airflow guide component 5 is disposed inside the driver housing 1. The airflow guide component 5 is located below the circuit board 4. The airflow guide component 5 is used to guide the airflow from the cooling fan 3 towards the circuit board 4 in a left-right back-and-forth motion.

[0028] like Figure 5As shown, the airflow guiding assembly 5 includes two limiting plates 51 fixedly mounted on the bottom inner side of the driver housing 1. The two limiting plates 51 are symmetrical about the cooling fan 3. Multiple air guide plates 52 are rotatably mounted between the two limiting plates 51. A connecting plate 53 is provided above each of the two limiting plates 51, and the multiple air guide plates 52 are rotatably connected to the two connecting plates 53. A fixing rod 54 is provided on one side of each of the two limiting plates 51. The fixing rod 54 is fixedly connected to the bottom inner side of the driver housing 1, and a helical spring 55 is fixedly connected to the fixing rod 54. One end of each of the two helical springs 55 is fixedly connected to the two connecting plates 53 respectively. A half gear 56 is rotatably mounted on one of the limiting plates 51. A transmission gear 57 is provided on one side of the half gear 56. The transmission gear 57 is rotatably connected to the limiting plate 51 and is connected to one of the air guide plates 52. A drive motor 58 is provided on one side of the half gear 56. The output end of the drive motor 58 is connected to the half gear 56. The drive motor 58 is fixedly connected to the bottom of the inner side of the driver housing 1.

[0029] The wind direction guide component 5 is used to guide the airflow from the cooling fan 3 to the circuit board 4 in a back-and-forth motion. This increases the heat dissipation range of the circuit board 4, thereby reducing the need to add a cooling fan 3 to increase the heat dissipation range of the circuit board 4, and thus effectively reducing the production cost of the device.

[0030] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, multiple mounting plates 7 are fixedly installed on the inner wall of the driver housing 1, and a cover 8 is provided on the upper end face of the driver housing 1. The cover 8 is fixedly connected to the upper end face of the multiple mounting plates 7. Mounting grooves 9 are opened on both sides of the upper end face of the support plate 2, and multiple support columns 10 are fixedly installed on the bottom inner side of the driver housing 1. The circuit board 4 is fixedly connected to the top of the multiple support columns 10.

[0031] The cover 8 serves to protect the inside of the driver housing 1 from dust. The mounting plate 7 is used to fix the cover 8 to the driver housing 1. The support column 10 not only supports the circuit board 4, but also fixes the driver housing 1 to the circuit board 4 together.

[0032] The working principle of this practical application is as follows:

[0033] When cooling the circuit board 4 inside the driver housing 1, the cooling fan 3 and drive motor 58 are started. The start of the cooling fan 3 will deliver the outside air to the circuit board 4 inside the driver housing 1. The start of the drive motor 58 will drive the half gear 56 to rotate. When the transmission teeth on the half gear 56 mesh with the transmission gear 57, the half gear 56 will drive the transmission gear 57 to rotate. The rotation of the transmission gear 57 will drive the air guide plate 52 connected to it to rotate. The air guide plate 52 will drive the other air guide plates 52 to rotate together through the connecting plate 53. When the transmission teeth of the half gear 56 and the transmission gear 57 disengage, the rotation of the air guide plate 52 will guide the air blown by the cooling fan 3 to the circuit board 4 back and forth, which can improve the heat dissipation range of the circuit board 4. The air after cooling the circuit board 4 will be discharged from the driver housing 1 through the heat dissipation window 6.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
