Description
Technical Field
[0001] This utility model relates to the field of DC servo driver technology, specifically a DC servo driver with a protective structure. Background Technology
[0002] In industrial control and other applications, the stable operation of DC servo drives is crucial. However, most existing DC servo drives have a one-piece molded housing with filters located inside the heat dissipation holes. Cleaning and maintaining these filters is inconvenient, requiring complex disassembly processes that are time-consuming and labor-intensive. Furthermore, the lack of an effective cushioning structure makes the housing susceptible to deformation from external impacts, which can damage internal components and reduce equipment reliability. Therefore, there is an urgent need for a DC servo drive structure that can address issues such as heat dissipation, dust prevention, easy cleaning, and cushioning protection. Utility Model Content

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1 to 4This utility model provides a technical solution: a DC servo driver with a protective structure, including a driver housing 1. One side of the driver housing 1 has a hollow structure. The top and bottom of the hollow structure side of the driver housing 1 are provided with slots 21. A filter protection assembly 3 is slidably installed in the slots 21. The filter protection assembly 3 includes a heat sink 31, a compression spring 34, a protective plate 35, and a filter assembly. The heat sink 31 is slidably installed in the slots 21. The top and bottom of the slots 21 are provided with arc-shaped retaining strips 32 that are adapted to the shape of the slots 21. The arc-shaped clip 32 is slidably disposed in the clip groove 21. Multiple air slots 33 are equally spaced on the clip groove 21. A mesh slot 36 is provided on one side of the heat dissipation plate 31. The filter assembly is slidably installed in the mesh slot 36. A column 34a is fixedly connected to the four corners and the center of one side of the heat dissipation plate 31. A compression spring 34 is sleeved on the column 34a. A through hole is provided on the protective plate 35. The column 34a slides through the through hole of the protective plate 35. A threaded hole is provided at one end of the column 34a. A bolt is installed in the threaded hole for fixing the protective plate 35.
[0018] Furthermore, the filter assembly consists of a filter frame 37 and a filter 38. The filter 38 is fixedly installed inside the filter frame 37, and the filter frame 37 is slidably installed inside the mesh slot 36. A push-pull column is fixedly connected to one side of the filter frame 37.
[0019] Furthermore, a heat dissipation fin 2 is installed on the side of the driver housing 1 away from the filter protection component 3. The heat dissipation fin 2 is made of aluminum alloy. Multiple hollow slots are opened on the protective plate 35. The hollow slots on the protective plate 35 are vertically distributed with the air duct 33.
[0020] Furthermore, the heat sink 31 is fixed to the driver housing 1 by screws.
[0021] The working process of this utility model is as follows:
[0022] like Figure 1 - Figure 4As shown, when the DC servo driver is working, the heat generated by the internal components is dissipated through the perforated driver housing 1. External cool air flows into the driver under the guidance of the heat sink 31 and air duct 33, exchanging heat with the hot air, thus effectively reducing the internal temperature of the driver and ensuring its operational stability and reliability. Simultaneously, the heat sink 2 also plays a supporting role in heat dissipation, further enhancing the cooling effect. The filter and protection assembly 3 not only achieves heat dissipation but also prevents external dust and impurities from entering the driver. When air passes through the filter assembly, dust and impurities are effectively filtered by the filter body 38, ensuring relatively clean air entering the driver, protecting the internal components, and extending their service life. When subjected to external impact, the protective plate 35 and compression spring 34 provide cushioning. The compression spring 34 is elastic and can absorb some energy when it is impacted, reducing the impact on the internal components of the driver and thus protecting the driver. When the filter needs to be cleaned or replaced, the operator can pull the filter frame 37 out of the screen groove 36 through the push-pull column to easily maintain the filter and reduce the difficulty and cost of maintenance.
[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
