Technical Field
[0001] This utility model relates to the field of cable performance testing technology, specifically to a charging pile cable performance testing device. Background Technology
[0002] With the rapid popularization of electric vehicles, the construction and maintenance of charging infrastructure are becoming increasingly important. Charging pile cables, as key components connecting charging piles and electric vehicles, are subject to frequent bending and stretching during use. Their mechanical properties, especially the ultimate bending angle and tensile strength, directly affect safety and durability. Therefore, precise bending angle limit testing and simple tensile performance testing of charging pile cables are essential steps in the production and quality inspection processes. Currently, the industry generally recognizes the need for specialized equipment to assess the cable's resilience under repeated bending and tensile stress to ensure it meets the requirements for long-term reliable operation.
[0003] There are simple devices in the existing technology for cable bending tests. These devices usually include clamps for fixing the cable ends. During the test, the cable is bent between two fixed points by manual or simple mechanical means. The core of these devices is to provide clamping capacity and generate bending action. However, such existing devices have difficulty in accurately controlling the applied bending angle during the bending test, and they lack effective means to measure the bending angle in real time and quantitatively.
[0004] Based on the closest existing technology mentioned above, the main technical problems are as follows: First, manual or simple mechanical bending methods cannot guarantee the uniformity and controllability of bending angle changes, and cannot accurately simulate the bending process in actual use, resulting in poor repeatability and low accuracy of test results; Second, there is a lack of effective angle quantitative indication devices, and operators cannot read the precise angle value of the cable during the bending process in real time and intuitively. They can only estimate or judge based on experience after the test, and cannot accurately record the limit bending angle when the cable sheath breaks.
[0005] Based on this, the present invention designs a charging pile cable performance testing device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0020] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8 A charging pile cable performance testing device includes a base plate 1, which serves as the installation foundation for the entire device and provides a stable support platform for other components. It also includes a clamping mechanism and a synchronous tensioning mechanism. The clamping mechanism is used to fix the cable under test, and the synchronous tensioning mechanism is used to perform synchronous bending tests on the cable. A fixing frame 2 is fixedly connected to the upper side of the base plate 1. The fixing frame 2 serves as the main support structure for installing and fixing other functional components. Two sets of mounting seats 3 are fixedly connected to the upper side of the fixing frame 2. The mounting seats 3 serve as rotating support components for installing and supporting rotating seats 4. Rotating seats 4 are rotatably connected to the inner side of the mounting seats 3. The rotating seats 4 serve as cable clamping and rotating components for fixing the cable and performing bending actions. The two sets of rotating seats 4 are installed perpendicular to each other, which facilitates standard bending tests on cables.
[0021] The inner side of the rotating base 4 is provided with an installation groove 5, which serves as a cable placement channel to accommodate the cable to be tested. A clamping plate 6 is slidably connected to the inner side of the rotating base 4. The clamping plate 6 is a movable clamping component used to clamp the cable in conjunction with the installation groove 5. A sliding groove 7 is provided on the inner side of the rotating base 4. The sliding groove 7 serves as a guide structure to limit the movement trajectory of the clamping plate 6. A locking block 8 is fixedly connected to one side of the clamping plate 6. The locking block 8 is a sliding engagement component used to engage with the sliding groove 7 to achieve the limiting sliding of the clamping plate 6. The locking block 8 is slidably connected to the inner side of the sliding groove 7. This engagement method ensures that the clamping plate 6 moves smoothly and reliably. The installation groove 5 and the bottom groove of the clamping plate 6 are compatible with the charging pile cable. This design ensures that cables of different specifications can be clamped.
[0022] The clamping mechanism is installed between the rotating seat 4 and the clamping plate 6. The clamping mechanism includes a screw 9, a push plate 11, and a positioning nut 12. The screw 9 serves as an adjusting component to drive the movement of the clamping plate 6. The screw 9 is threaded to the upper side of the rotating seat 4. This connection method facilitates the adjustment of the clamping force. A slot 10 is provided on the upper side of the clamping plate 6. The slot 10 serves as a mating structure to cooperate with the push plate 11. The push plate 11 is fixedly connected to the bottom of the screw 9. The push plate 11 serves as a transmission component to convert the rotational movement of the screw 9 into the linear movement of the clamping plate 6. The push plate 11 is also limited to a rotational connection to the inner side of the slot 10. This connection method ensures reliable transmission. The positioning nut 12 is threaded to the outside of the screw 9. The positioning nut 12 serves as a locking component to fix the position of the screw 9. The positioning nut 12 abuts against the upper side of the rotating seat 4. This arrangement facilitates operation and fixation.
[0023] Both sets of rotating seats 4 are fixedly connected to the outside of a connecting ring 15. The connecting ring 15 serves as a connecting component and is used to connect with the synchronous tensioning mechanism. A hanging ring 16 is attached to the outside of the connecting ring 15. The hanging ring 16 serves as a transition connector and is used to achieve a detachable connection between the connecting rope 17 and the connecting ring 15.
[0024] The synchronous tensioning mechanism is installed on the upper side of the fixed frame 2. The synchronous tensioning mechanism includes a rotating rod 14 and a connecting rope 17. The rotating rod 14 serves as a power transmission component, used to transmit the power of the drive motor 13. The rotating rod 14 is rotatably connected to the upper side of the fixed frame 2. This arrangement ensures smooth rotation. The installation position of the rotating rod 14 is equal to the distance between the two sets of mounting seats 3. This symmetrical arrangement ensures balanced force. The connecting rope 17 is fixedly connected to the outside of the rotating rod 14. The connecting rope 17 serves as a traction component, used to pull the rotating seat 4 to rotate. There are two sets of connecting ropes 17. This double rope design ensures synchronous action. The ends of the two sets of connecting ropes 17 are respectively fixedly connected to the outside of the two sets of hanging rings 16. This connection method achieves synchronous traction. The drive motor 13 is fixedly connected to the lower side of the fixed frame 2. The drive motor 13 serves as a power source, providing power for testing. The rotating rod 14 and the output shaft of the drive motor 13 are fixedly connected. This direct connection method ensures transmission efficiency.
[0025] An angle dial 18 is fixedly connected to the upper side of the fixed frame 2. The angle dial 18 serves as an angle indicator to display the rotation angle of the rotating seat 4. The angle dial 18 is installed at a height below the lower surface of the two sets of rotating seats 4. This arrangement facilitates observation and reading. The angle dial 18 has a quarter-circle structure, which is suitable for measuring bending angles. The two sets of rotating seats 4 are symmetrically arranged with the axis of the angle dial 18. This symmetrical design ensures accurate measurement.
[0026] A tensile testing mechanism is installed on the upper side of the mounting bracket 2. The tensile testing mechanism is used to perform tensile performance testing on the cable. The tensile testing mechanism includes a positioning seat 19, a positioning plate 20, and a fixing bolt 21. The positioning seat 19 serves as a fixed base for fixing the cable end. The positioning seat 19 is fixedly connected to the upper side of the mounting bracket 2. This fixing method ensures test stability. The positioning seat 19 is located on one side of one of the rotating seats 4. This arrangement facilitates tensile testing. The fixing bolt 21 is threadedly connected to the upper side of the positioning seat 19 and the positioning plate 20. The fixing bolt 21 serves as a fastener for fixing the positioning plate 20. The positioning plate 20 and the positioning seat 19 can be detached and installed through the fixing bolt 21. This design facilitates the installation and removal of the cable.
[0027] In this embodiment, when testing the maximum bending angle that the charging pile cable can withstand, firstly, the two sets of rotating seats 4 are moved to a mutually perpendicular position. The cable to be tested is placed in the mounting groove 5 inside the rotating seat 4. By turning the screw 9, the push plate 11 at the bottom of the screw 9 moves downward. Under the pushing of the push plate 11 and the limiting action of the sliding groove 7 and the locking block 8, the clamping plate 6 moves quickly towards the mounting groove 5, tightly abutting and clamping the cable in the mounting groove 5. Then, the positioning nut 12 is tightened to press against the upper surface of the rotating seat 4, thereby quickly locking the screw 9 and completing the stable clamping of cables of different thicknesses.
[0028] After clamping, start the drive motor 13 to drive the rotating rod 14 to rotate and wind the two sets of connecting ropes 17. The ends of the connecting ropes 17 are hooked to the connecting rings 15 through the hanging rings 16. As the connecting ropes 17 are wound and tightened, the two sets of hanging rings 16 pull the two sets of rotating seats 4 to rotate in opposite directions with the mounting seat 3 as the fulcrum, thereby forcing the cable located between the two sets of rotating seats 4 to bend. During the bending process, the operator can clearly read the real-time included angle between the two sets of rotating seats 4 by observing the indicated position of the edge of the rotating seat 4 on the angle dial 18 on the upper side of the fixed frame 2. Continue to run the drive motor 13 to gradually reduce the bending angle of the cable until the outer sheath of the cable cracks. At this time, record the included angle data indicated on the angle dial 18 to intuitively obtain the maximum bending angle that the cable can withstand.
[0029] In addition, the device can also perform tensile testing. The end of the cable is placed in the positioning seat 19 on the upper side of the fixed frame 2, and then the positioning plate 20 is placed on top of it. The positioning plate 20 is then fastened to the positioning seat 19 using the fixing bolts 21, thereby firmly installing the end of the cable in the positioning seat 19. At this time, the drive motor 13 is turned to drive the rotating seat 4 to rotate away from the positioning seat 19, so that tensile force can be applied between the cable segment clamped in the rotating seat 4 and the cable end fixed in the positioning seat 19, realizing a simple tensile performance test of the cable. Thus, the device integrates bending angle detection and tensile testing functions, making the testing function more comprehensive.
