[0002] Stepper motor drivers are crucial devices for controlling the operation of stepper motors and are widely used in industrial automation, medical devices, and smart homes. Stepper motor drivers generate a significant amount of heat during operation. If this heat cannot be dissipated in time, the temperature of the internal components will rise, affecting their operational stability and lifespan. Currently, most stepper motor driver housings on the market use a simple box-like structure, relying solely on passive heat dissipation through the housing surface, resulting in low heat dissipation efficiency. Furthermore, stepper motor drivers typically require manual installation and maintenance, and the sharp edges of the housing can easily cause discomfort and scratches. Utility Model Content

[0007] Furthermore, the housing cover is provided with terminal plug-in interfaces, indicator light ports, and DIP switch mounting ports that are connected internally and externally; the plug-in terminals, indicator lights, and DIP switches of the driver are connected to the driver circuit board via soldered pins.

[0008] Furthermore, the edge of the arc corner is provided with a slot, and the edge of the arc corner cover is provided with a insertion ridge, which is movably inserted into the slot.

[0009] Furthermore, the horizontal mounting plate, the vertical mounting plate, and the heat dissipation fin plate are integrally formed metal profiles, and the thickness of the heat dissipation fin plate is less than the thickness of both the horizontal mounting plate and the vertical mounting plate.

[0018] 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.

[0019] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Combination such as Figures 1-6 As shown in the summary, in this embodiment, a stepper motor driver housing includes a housing base 1 and a housing cover 13, which are joined by screws to form a closed space for mounting the driver circuit board.

[0020] Specifically, the shell base 1 is made of a one-piece molded metal profile (preferably aluminum profile, which combines lightweight and good thermal conductivity), including a vertically connected horizontal mounting plate 1a and a vertical mounting plate 1b. Several heat dissipation fins 1c are vertically connected to the vertical mounting plate 1b, and the heat dissipation fins 1c are located above and parallel to the horizontal mounting plate 1a. The number of heat dissipation fins 1c can be selected according to the driver power, for example, 7 fins. The spacing between two adjacent heat dissipation fins 1c is 9mm, ensuring sufficient heat dissipation area while avoiding thermal interference between fins. The thickness of the heat dissipation fins 1c is less than the thickness of the horizontal mounting plate 1a and the vertical mounting plate 1b to optimize heat dissipation efficiency while ensuring structural strength.

[0021] A through hole 1d is vertically arranged in the center of the heat sink fin plate 1c, and an active cooling unit 1e can be detachably inserted into the through hole 1d. The active cooling unit 1e includes a columnar impeller cover 1e-1. An air inlet 1e-2 and an air outlet 1e-3 are arranged opposite each other on the side of the impeller cover 1e-1. An impeller 1e-4 is arranged between the air inlet 1e-2 and the air outlet 1e-3. The impeller 1e-4 is driven to rotate by a motor 1e-5. The power receiving terminal on the motor 1e-5 is connected to the driver circuit board through a circuit. The motor 1e-5 is detachably connected to the heat sink fin plate 1c at the highest point through a motor mount 1e-6 (e.g., by screws). The motor mount 1e-6 is fixedly connected to the impeller cover 1e-1. By changing the direction of the air inlet 1e-2 and the air outlet 1e-3, the direction of the cooling airflow can be switched to adapt to different installation layouts of the driver.

[0022] The two corners of the heat sink fin plate 1c furthest from the vertical mounting plate 1b are rounded, and an arc-shaped cover 1f is provided on the rounded corners. Slots are provided on the edges of the rounded corners, and insertion ribs 1f-1 are provided on the edges of the arc-shaped cover 1f. The insertion ribs 1f-1 are movably inserted into the slots. The top of the arc-shaped cover 1f is connected to the highest heat sink fin plate 1c by screws, facilitating disassembly and maintenance. Two arc-shaped covers 1f are symmetrically arranged, and both are equidistant from the active cooling unit 1e. Ventilation recesses 1f-2 are provided near the end of the arc-shaped cover 1f on the vertical mounting plate 1b. Each ventilation recess 1f-2 is located between two adjacent heat sink fin plates 1c, further optimizing airflow for heat dissipation.

[0023] On the other hand, specifically, the housing 13 has a terminal connector 13a, an indicator light port 13b, and a DIP switch mounting port 13c that connect internally and externally. The terminals, indicator lights, and DIP switches are connected to the driver circuit board via soldered pins. The terminal connector 13a is used to connect power, control signals, and motor winding leads; the indicator light port 13b is used to mount indicator lights to display the driver's operating status; the DIP switch mounting port 13c is used to mount DIP switches to flexibly set parameters such as motor current and microstepping. The terminal connector 13a and indicator light port 13b are adjacent and located on the upper surface of the housing 13, while the DIP switch mounting port 13c is located on the side of the housing 13, a reasonable layout that facilitates operation. The upper surfaces of the housing base 1 and the housing 13 are flush, ensuring the overall flatness of the appearance.

[0024] The stepper motor driver housing provided by this utility model achieves efficient heat dissipation through the combination of an active heat dissipation unit and a heat dissipation fin plate. The arc-shaped cover eliminates sharp edges to ensure safe grip, while also having the advantage of flexible parameter adaptation. It effectively solves the shortcomings of the prior art and has high practical value.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. It should be noted that for those skilled in the art, any changes, modifications or additions without departing from the concept of the present utility model should fall within the protection scope of the present utility model.
