Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] The electric roller controller provided by this utility model, such as Figure 1-4As shown, the device includes a PCB circuit board 1, a housing 2, and a pressing structure 3. The PCB circuit board 1 integrates a CAN communication circuit, a power supply circuit, multiple piercing structures 11, and multiple electric roller interfaces 12. The electric roller interfaces 12 are used to connect external electric roller cables, and their number can be expanded according to the application scenario. In this embodiment, two electric roller interfaces 12 are preferably provided to support simultaneous control of two external electric rollers. The piercing structures 11 have sharp piercing ends 112 for piercing the cable insulation layer to achieve electrical connection between the conductor and the PCB circuit board 1. This embodiment configures four piercing structures 11, divided into two groups. The first group of two piercing structures 11 is used to achieve electrical conduction between the power cable and the power supply circuit, and the second group of two piercing structures 11 is used to achieve electrical conduction between the CAN cable and the CAN communication circuit. The housing 2 is used to house the PCB circuit board 1, including a base 21 and a cover 22 that covers the base 21, forming a sealed protective space. The PCB circuit board 1 is fixedly mounted on the base 21, and the pressing structure 3 is located on the upper surface of the cover 22. Specifically, the pressing structure 3 includes a pressing plate 31, a pair of fixed posts 32, and a rotating shaft 33. The two fixed posts 32 are spaced apart along the length of the cover 22 on the upper surface of the cover 22. The rotating shaft 33 is rotatably inserted between the two fixed posts 32. One end of the pressing plate 31 is fixed to the rotating shaft 33, and the other end is a free end. When the free end of the pressing plate 31 is pressed down, its pressure is precisely applied to the piercing end 112 of the piercing structure 11, driving the tip of the piercing end 112 to pierce the cable insulation layer and establish a reliable electrical connection.

[0032] This invention, through the coordinated design of the piercing structure 11 and the pressing structure 3, enables direct electrical connection between the CAN cable, power cable, and PCB circuit board, solving the problems of complex procedures, low reliability, and large space occupation associated with traditional wiring methods. Furthermore, the pressing structure, through the lever principle of a rotating shaft, enables precise transmission of downward pressure.

[0033] Specifically, the piercing structure 11 is a metal conductor, including a fixed end 111 and a piercing end 112. The fixed end 111 is cylindrical, and its bottom is fixedly mounted on the PCB circuit board 1. The piercing end 112 is conical, and its tip penetrates the cover 22 and protrudes from the upper surface of the cover 22, for piercing the insulation layer of the CAN line.

[0034] To further precisely control the downward stroke of the pressure plate 31 and prevent the piercing end 112 from excessively penetrating the cable and causing conductor damage, this utility model provides two sets of baffles 221 on the upper surface of the cover 22. Each set of baffles 221 is arranged at intervals along the width direction of the cover 22 and includes two opposing baffles 221. The first set of baffles 221 is dedicated to power line positioning, and the second set of baffles 221 is dedicated to CAN line positioning. Specifically, in conjunction with... Figure 3As shown, the baffle 221 extends along the length of the cover 22 and has a concave geometric cross-section, including a pressure-bearing area 2211 in the middle and limiting areas 2212 on both sides of the pressure-bearing area 2211. The height of the limiting areas 2212 is higher than the height of the pressure-bearing area 2211. The pressure-bearing area 2211 is located below the lower pressure plate 31 and serves as a stop surface for the lower pressure plate 31. Its upper surface is higher than the tip of the puncture end 112 by a predetermined distance. When pressed down, the lower surface of the lower pressure plate 31 abuts against the upper surface of the pressure-bearing area 2211 of the baffle 221. It should be noted that during the piercing connection, the cable must first be placed horizontally above the tip of the piercing end 112. Then, the lower pressure plate 31 is pressed down until its lower surface abuts against the upper surface of the pressure-bearing area 2211. To ensure that the tip of the piercing end 112 pierces the cable's insulation layer without damaging the conductor, the height h between the upper surface of the pressure-bearing area 2211 and the tip of the piercing end 112 is equal to the cable's outer diameter minus the insulation layer's thickness. This way, when the lower pressure plate 31 abuts against the upper surface of the pressure-bearing area 2211, it can just pierce the cable's insulation layer without damaging the conductor structure. Additionally, a limiting block 2213 is provided on the upper part of the relative inner side of the limiting area 2212 of each set of baffles 221. After the cable passes between two baffles 221 in the same set, it is limited within the space below the limiting block 2213 to prevent vibration displacement.

[0035] Furthermore, the lower pressure plate 31 is pressed and fixed to the upper surface of the cover 22 by the fixing bolt 4. Specifically, the fixing bolt 4 is detachably inserted through the corresponding mounting holes on the lower pressure plate 31, the cover 22 and the base 21, for pressing and fixing the lower pressure plate 31 to the upper surface of the cover 22.

[0036] The piercing installation process of the cable of this utility model is as follows:

[0037] Step 1: Remove the fixing bolt 4 to allow the lower pressure plate 31 to rotate freely;

[0038] Step 2: Lift the lower pressure plate 31 to its maximum angle to expose the tip of the piercing end 112 of the piercing structure 11;

[0039] Step 3: Thread the cable under the limiting block 2213 of each set of baffles 221, and place the cable horizontally on top of the pressure-bearing area 2211;

[0040] Step 4: Hold the free end of the lower pressure plate 31 and press it down so that the lower surface of the lower pressure plate 31 abuts against the upper surface of the pressure-bearing area 2211 of the baffle 221.

[0041] Step 5: Tighten the fixing bolt 4.

[0042] In summary, this utility model achieves efficient and reliable connection of the CAN line through the coordinated design of the piercing structure 11, the pressing structure 3, and the baffle 221, and is simple and convenient to operate.

[0043] Furthermore, the PCB circuit board of this utility model also integrates two sets of sensor interfaces 13, a control panel interface 14, and multiple status feedback lights 15. The sensor interfaces 13 are used to connect position / temperature sensor cables, the control panel interface 14 is used to connect to the human-machine interface control panel, and the electric roller status feedback lights 15 are used to indicate the operating status of the equipment. The side wall of the cover 22 has two electric roller interface holes 222 and two sensor interface holes 223. The electric roller interface holes 222 correspond one-to-one with the plug-in ends of the electric roller interface 12, allowing external electric roller cables to be plugged in. The sensor interface holes 223 correspond one-to-one with the plug-in ends of the sensor interface 13, allowing external sensor cables to be plugged in.

[0044] In addition, the upper surface of the cover 22 has an interface hole 224 for the control panel and multiple light-transmitting holes 225. The interface hole 224 is aligned with the plug end of the control panel interface 14 for vertical insertion of the control panel cable. The multiple light-transmitting holes 225 are set one-to-one with each status feedback light 15, so that the light is transmitted outward for display.

[0045] In summary, the electric roller controller of this utility model has a high degree of integration, can monitor and control two electric rollers simultaneously, and can intuitively see the operating status of the equipment through indicator lights, demonstrating a high degree of automation and intelligence.

[0046] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
