[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a multi-channel constant current source device, including a mounting shell 1, a maintenance top cover 2 rotatably connected to one side surface of the mounting shell 1, a component mounting mechanism 3 provided on one side surface of the mounting shell 1, a steady-state heat dissipation mechanism 4 provided on the inner wall surface of the mounting shell 1, a power input interface 5, a network interface 6, a function switch 7 and a power output interface 8 attached to one side surface of the mounting shell 1, and a functional motherboard 9 attached to one side surface of the component mounting mechanism 3;

[0024] The component mounting mechanism 3 includes a mounting base 301, which is fixedly connected to the inner wall surface of the mounting housing 1. A mounting base 302 is fixedly connected to the upper surface of the mounting base 301. A drive motor 303 is mounted on one side surface of the mounting base 302. A linkage gear 304 is fixedly connected to one side surface of the drive motor 303. A linkage belt 305 is attached to the outer surface of the linkage gear 304. A drive screw 306 is fixedly connected to one side surface of the linkage gear 304. A threaded connection is made to the outer surface of the drive screw 306. The mounting clamp 307, through the component mounting mechanism 3, enables the drive motor 303 to drive the linkage gear 304 to rotate during use. The linkage gear 304 drives five sets of linkage gears 304 to rotate via the linkage belt 305. The linkage gear 304 drives the drive screw 306 to rotate. The drive screw 306 drives the mounting clamp 307 to slide along the slide groove of the mounting base 302, positioning and clamping the functional motherboard 9. This allows for precise and rapid positioning and clamping of the functional motherboard 9, preventing component displacement during installation and improving installation efficiency and stability.

[0025] Furthermore, five sets of power output interfaces 8 and function motherboards 9 are equidistantly arranged on one side surface of the mounting housing 1. Each set of power output interfaces 8 corresponds to a set of function motherboards 9. Through the arrangement of power output interfaces 8 and function motherboards 9, multi-channel independent constant current output can be achieved during use, meeting the simultaneous working needs of multiple external devices and improving the applicability and working efficiency of the device.

[0026] Furthermore, there are five sets of linkage gears 304. Each set of linkage gears 304 is attached to one side surface of each functional motherboard 9. Through the setting of linkage gears 304, during use, the five sets of functional motherboards 9 can be synchronously and stably positioned and clamped by the mounting clamp 307, ensuring the consistency and reliability of the installation and reinforcement of each functional motherboard 9.

[0027] Furthermore, a groove is provided on one side surface of the linkage belt 305. The shape and size of the groove match the outer surface of the linkage gear 304. By setting the linkage belt 305, the contact area and friction between the linkage belt 305 and the linkage gear 304 can be increased during use, ensuring the stability and reliability of power transmission, effectively preventing slippage, and improving the working efficiency and stability of the component installation mechanism 3.

[0028] Furthermore, the steady-state heat dissipation mechanism 4 includes a heat dissipation base 401, which is fixedly connected to the inner wall surface of the inspection top cover 2. A ventilation plate 402 is fixedly connected to the inner wall surface of the heat dissipation base 401. A heat dissipation grid 403 is fixedly connected to the upper surface of the ventilation plate 402. A fixing rod 404 is fixedly connected to one side surface of the heat dissipation grid 403. A cooling fan 405 is fixedly connected to the upper surface of the heat dissipation grid 403. With the setting of the steady-state heat dissipation mechanism 4, when in use, the cooling fan 405 drives the airflow, so that the external air and the inside of the mounting housing 1 form a cooling airflow circulation. The porous ventilation plate 402 facilitates airflow. Heat is conducted through the ventilation plate 402 to the heat dissipation grid 403 exhaust device, which can effectively form a cooling airflow circulation and quickly conduct away the heat generated by the functional motherboard 9, ensuring the steady-state operation of the device.

[0029] Furthermore, one side surface of the ventilation plate 402 is porous. The cooling fan 405 is fixedly connected to one side surface of the ventilation plate 402 through the heat dissipation grid 403. With the ventilation plate 402 and the heat dissipation grid 403, the porous structure facilitates airflow and forms a cooling air duct circulation during use. The airflow driven by the cooling fan 405 is evenly dispersed through the heat dissipation grid 403, which can more efficiently conduct away the heat generated by the main board 9, improve heat dissipation efficiency, and ensure the stable operation of the device.

[0030] Furthermore, three sets of cooling fans 405 are equidistantly arranged on one side surface of the heat dissipation base 401, and five sets of steady-state heat dissipation mechanism 4 are equidistantly arranged on the upper surface of the inspection top cover 2. Through the arrangement of cooling fans 405, the airflow in the cooling duct can be made more uniform and efficient during use, quickly removing the heat generated by the functional motherboard 9 and improving the heat dissipation effect. Through the arrangement of steady-state heat dissipation mechanism 4, the five sets of functional motherboards 9 can be targeted for heat dissipation during use, ensuring that each functional motherboard 9 is at a suitable operating temperature, thereby improving the overall stability and reliability of the device.

[0031] Working Principle: When the equipment starts running, the external power supply powers the entire system. Before starting, the functional mainboard 9 needs to be installed and reinforced. First, rotate the inspection top cover 2 to directly observe the installation space inside the mounting housing 1. Fix the PCB circuit board of the constant current source control output, i.e., the functional mainboard 9. Slide the five sets of functional mainboards 9 along the upper surface of each mounting base 302 until they are in contact with the upper surface of the mounting base 302. After installation, start the drive motor 303. The drive motor 303 drives the linkage gear 304 to rotate. The rotation of the linkage gear 304 drives the linkage belt 305 to rotate, which in turn drives the five sets of linkage gears 304 to rotate together. The rotation of the linkage gears 304 drives the drive screw 306 to rotate. The rotation of the drive screw 306 then drives the mounting clamp 307, which is threaded to the outer surface of the drive screw 306, to slide along the sliding surface of one side of the mounting base 302. The slot slides to position and clamp the functional motherboard 9, preventing component displacement during installation. After installation, the inspection cover 2 is closed, the power input interface 5 and network interface 6 are connected, and the function switch 7 is pulled. After processing by the functional motherboard 9, a stable current is output to multiple external devices through the power output interface 8. While processing the current intensity, the functional motherboard 9 generates heat due to the current thermal effect. Air is driven by the cooling fan 405, and the external air and the interior of the mounting shell 1 form a cooling air duct circulation. The porous ventilation plate 402 facilitates air circulation, and the heat is conducted out of the device through the solid plate ventilation plate 402 and the heat dissipation grid plate 403 fixedly connected to one side of the ventilation plate 402, thus completing the heat dissipation and achieving stable operation of the device. The drive motor 303 is model YE2-132S-4. This completes the use of a multi-channel constant current source device.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
