[0016] This invention also proposes a method for using an intelligent power supply controller for power supply stations, comprising the following steps:

[0017] Step S1: During equipment installation, multiple data cables at the rear of the enclosure are clamped and fixed between the pressure plate and the base plate. The pressure plate and the base plate form a ring structure through the arc groove and the slot. Under the elastic force of the first spring, the data cables can be clamped and fixed between the pressure plate and the base plate.

[0021] Step S5: Before the moving plate approaches the corresponding button position, the third spring is energized and contracts, which can drive the pressing shaft to move towards the moving plate. When the moving plate is directly opposite the button, the third spring is de-energized and drives the pressing shaft to move, which can directly squeeze the button to achieve remote switch control and emergency braking effect.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. When staff are not around the equipment and need to perform emergency operations, the first motor in the moving mechanism is started to make the two shafts rotate synchronously, so that the two first gears rotate at the same time. Then the moving mechanism can move up and down along the tooth groove, so that the moving plate is close to the button that needs to be operated, thereby enabling remote operation of the button.

[0024] 2. When the moving plate approaches the corresponding button, the third spring is de-energized, causing the pressing shaft to move. Then, one end of the pressing shaft can directly press the button, achieving remote switch control and effective emergency braking. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Reference Figures 1-4 A smart power supply controller for power supply includes a housing 1, a control panel 6 is provided inside the housing 1, multiple buttons are provided at the front of the control panel 6, multiple data cables are provided at the rear of the control panel 6, the rear of the housing 1 is enclosed by a mesh plate 4, and the front of the housing 1 is enclosed by a cabinet door 2.

[0038] An L-shaped plate 3 is provided at the lower rear of the box 1. An installation mechanism is provided within the range of the L-shaped plate 3 inside the box 1. The installation mechanism includes a base plate 11 and multiple pressure plates 14 that abut against the surface of the base plate 11.

[0039] The inner walls on both sides of the front part of the housing 1 are provided with toothed grooves 7. A moving mechanism 9 is provided between the two toothed grooves 7. The moving mechanism 9 includes a fixed shaft 17 and two first gears 23 rotatably installed at both ends of the fixed shaft 17. The two first gears 23 mesh with the toothed grooves 7 on both sides respectively. A moving plate 20 is slidably installed on the fixed shaft 17. An elastic mechanism is provided on the moving plate 20. The elastic mechanism includes a pressing shaft 26 and a third spring 27. The third spring 27 is sleeved on the pressing shaft 26. The pressing shaft 26 is slidably inserted into the moving plate 20.

[0040] Reference Figures 5-9 Each of the two first gears 23 has a fixedly inserted rotating shaft. One end of each rotating shaft is fixedly connected to a deflection shaft 24. The two deflection shafts 24 are connected by a linkage shaft 19, which is rotatably connected to the end of the deflection shaft 24 furthest from the rotating shaft. A limit shaft 22 is also slidably connected to the surface of one of the tooth grooves 7. A first motor 21 is fixedly mounted on the limit shaft 22, and the drive end of the first motor 21 is fixedly connected to the rotating shaft of one of the first gears 23. During use, the first motor 21 drives the rotating shaft to rotate via its drive end, which in turn drives the connected first gear 23 to rotate. As the first gear 23 rotates, it can move up and down relative to the tooth groove 7. Simultaneously, when one rotating shaft rotates, it can drive the fixedly connected deflection shaft 24 to deflect. The deflection of one deflection shaft 24 can drive the other deflection shaft 24 to deflect via the linkage shaft 19, thus achieving the rotation of both rotating shafts and the synchronous rotation of the two first gears 23, allowing them to move up and down along the two tooth grooves 7.

[0041] Reference Figures 5-9A rubber pad is provided at one end of the pressing shaft 26, facing the control panel 6. One end of the third spring 27 is connected to the rubber pad, and the other end is connected to the surface of the movable plate 20. A baffle 8 is provided on the top wall of the front of the housing 1. When the third spring 27 is energized, it can retract, and when de-energized, it can naturally extend. Thus, by controlling the energization and de-energization of the third spring 27, the pressing shaft 26 can be extended and retracted, thereby moving the rubber pad and achieving the effect of pressing the button. The baffle 8 on the top wall is used to enclose the movable mechanism 9, hiding the movable mechanism 9 inside.

[0042] Reference Figures 5-9 A second connecting block 32 is provided at one end of the fixed shaft 17, and a first connecting block 25 is provided at the other end of the fixed shaft 17. Two rotating shafts pass through the second connecting block 32 and the first connecting block 25 respectively. The first connecting block 25 is located at the end near the limiting shaft 22. A threaded rod 18 is also provided below the fixed shaft 17. The two ends of the threaded rod 18 are rotatably connected to the second connecting block 32 and the first connecting block 25 respectively. The threaded rod 18 is threaded through the movable plate 20. The threaded rod 18 is a rotatable structure located in the middle, with the second connecting block 32 and the first connecting block 25 provided at both ends respectively. The second connecting block 32 and the first connecting block 25 are set according to the different structural requirements of the components at both ends.

[0043] Reference Figures 5-9 A second motor 28 is fixedly mounted on the second connecting block 32. A second gear 29 is fixedly connected to the drive end of the second motor 28. A third gear 30 meshes with the lower part of the second gear 29. A fourth gear 31 is fixedly sleeved on one end of the threaded rod 18 near the second connecting block 32. The fourth gear 31 meshes with the third gear 30. The second motor 28 can drive the second gear 29 to rotate through its drive end. The second gear 29 can drive the meshing third gear 30 to rotate. The third gear 30 can drive the meshing fourth gear 31 to rotate, thereby enabling the threaded rod 18 to rotate. As the threaded rod 18 rotates, it can drive the movable plate 20 to move.

[0044] Reference Figures 5-9 The second gear 29 and the third gear 30 are arranged vertically and connected on one side by a connecting piece, which is fixedly connected to the fixed shaft 17. The fixed shaft 17 is a structure used to support the second gear 29 and the third gear 30, so that the positions of the second gear 29 and the third gear 30 remain stable.

[0045] Reference Figure 10The control panel 6 is equipped with a display screen, and the cabinet door 2 has a window corresponding to the display screen. Multiple heat sinks 5 for heat dissipation are located at the rear of the cabinet 1. Slide grooves are provided on both sides of the L-shaped plate 3, and sliders slide within these grooves. The sliders are fixedly installed on the inner wall of the cabinet 1. An opening is formed between the lower end of the L-shaped plate 3 and the bottom wall at the rear of the cabinet 1. When the L-shaped plate 3 is moved and flipped within the range of the slide grooves, the sliders move within the range of the grooves.

[0046] Reference Figure 10 Symmetrical locking blocks 10 are arranged on the inner wall of the rear of the housing 1. The two ends of the base plate 11 are respectively locked into two locking blocks 10. Multiple arc-shaped grooves are formed on the upper surface of the base plate 11, and multiple pressure plates 14 are formed on the lower surface of the base plate 11 with slots that cooperate with the arc-shaped grooves. The arc-shaped grooves and slots are used to lock data cables and wires. A fixing plate 33 is also provided on the base plate 11. A moving shaft 13 is fixedly connected to the pressure plate 14 and passes through the fixing plate 33. A first spring 15 is sleeved on the moving shaft 13. In order to ensure that the controller's data cables are orderly and stable, the pressure plate 14 is pressed against the base plate 11 under the elastic force of the first spring 15, pressing the data cables between the arc-shaped grooves and slots, and fixing them in an orderly manner.

[0047] Reference Figure 10 A first spring 15 is positioned between a fixed plate 33 and a pressure plate 14. A pull plate 12 is positioned above the fixed plate 33, and multiple movable shafts 13 pass through the pull plate 12. The pull plate 12 has multiple bends, and a second spring 16 is installed within each bend, connecting the pull plate 12 and the fixed plate 33. During use, operators can simultaneously pull multiple movable shafts 13 using the pull plate 12, allowing for simultaneous operation of multiple shafts and facilitating the connection and disconnection of data cables. The second spring 16 maintains stability.

[0048] A method for using an intelligent power supply controller for power supply includes the following steps:

[0049] Step S1: During equipment installation, multiple data cables at the rear of the housing 1 are clamped and fixed between the pressure plate 14 and the base plate 11. The pressure plate 14 and the base plate 11 form a ring structure through the arc groove and the slot. Under the elastic force of the first spring 15, the data cables can be clamped and fixed between the pressure plate 14 and the base plate 11, thereby arranging and integrating the data cables in an orderly manner. The fixed data cables can avoid shaking, ensuring the stability of the equipment operation when it is moved. During installation and fixing, the staff only needs to pull the pull plate 12 upward, which can drive the pressure plates 14 upward through the various moving shafts 13, thereby facilitating the clamping and fixing of the data cables. The data cables are covered by an L-shaped plate 3, which can protect the data cables.

[0050] Step S2: When staff are around the equipment, they can directly operate the control panel 6 to adjust the current and voltage and effectively control the switching on and off of the equipment.

[0051] Step S3: When the staff is not around the equipment and an emergency operation is required, the remote control, the moving mechanism and the equipment are not on the same circuit, and the first motor 21 in the moving mechanism 9 is started. The first motor 21 drives one of the first gears 23 to rotate through the drive end. The shaft of the first gear 23 rotates, and the shaft drives the linkage shaft 19 to move through the deflection shaft 24, which in turn drives the other deflection shaft 24 to deflect, thereby realizing the synchronous rotation of the two shafts, so that the two first gears 23 rotate at the same time. Then the moving mechanism 9 can move up and down along the tooth groove 7, so that the moving plate 20 is close to the button that needs to be operated.

[0052] Step S4: Rotate the threaded rod 18, and move the movable plate 20 back and forth along the fixed shaft 17, so that the movable plate 20 stops precisely at the corresponding button position. The second motor 28 drives the second gear 29 to rotate through the drive end. The second gear 29 drives the third gear 30 to rotate. The third gear 30 drives the fourth gear 31 to rotate, and finally realizes the rotation of the threaded rod 18. The threaded rod 18 passes through the movable plate 20, and the movable plate 20 is limited by the fixed shaft 17. As the threaded rod 18 rotates, the movable plate 20 can move.

[0053] Step S5: Before the moving plate 20 approaches the corresponding button position, the third spring 27 is energized and contracts, which can drive the pressing shaft 26 to move toward the moving plate 20. When the moving plate 20 is directly opposite the corresponding button, the third spring 27 is de-energized and drives the pressing shaft 26 to move. Then, one end of the pressing shaft 26 can directly squeeze the button to achieve remote switch control and achieve effective emergency braking.

[0054] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
