Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable technology, and more specifically, to a charging cable for new energy vehicles. Background Technology
[0002] In existing technologies, the connection method between charging cables and charging heads for new energy vehicles usually has several inconveniences. First, the connection and disassembly process is complicated and often requires considerable operating force or special tools to complete, which brings considerable trouble and inconvenience to users.
[0003] In traditional charging cable and charging head connection designs, due to the lack of an effective automatic docking and fastening mechanism, the connection between the cable and the charging head is often not tight enough. This loose connection may lead to unstable current transmission, poor contact during charging, and even safety hazards such as arc discharge or overheating. In addition, an unreliable connection may also affect charging efficiency and slow down the charging speed.
[0004] In existing technologies, the connection between the charging cable and the charging head usually relies on manual rotation or pulling to complete the disassembly operation. This operation is cumbersome and time-consuming, especially when the cable needs to be frequently disassembled and installed. Frequent plugging and unplugging operations may cause wear on the charging interface and cable end, shortening the service life of the device. Furthermore, if the connection design is not reasonable or there is a jamming phenomenon, the disassembly process may also result in jamming or difficulty in pulling out, increasing the difficulty of operation for users.

The cable connection mechanism includes a connecting wire, a mating wire, a mating hole, a mating block, and a side-push ring. The mating hole is located at one end of the mating wire, and the mating block is installed at one end of the connecting wire, engaging with the mating hole. The side-push ring is located on the sidewalls of the connecting wire and the mating wire. The push-tightening mechanism connects the connecting wire and the mating wire. The push-tightening mechanism includes a clamping tube, an inclined block, and... The clamping tube is equipped with a series of components including a tilting block, a push spring frame, an inner push ring, a connecting rod, and an outer shift ring. Multiple tilting blocks are symmetrically installed on the inner wall of the clamping tube. The tilting blocks are slidably connected to each other. The push spring frame is installed on the side of the tilting block and can press against the side of the mating line and the connecting line. The top end of the push spring frame pushes against the side push ring, so that the connecting line and the mating line are relatively tightly connected. The inner push ring moves directionally inside the clamping tube and is slidably connected to the tilting block. The connecting rod slides longitudinally on the clamping tube, and the outer shift ring slides longitudinally on the outer wall of the clamping tube. The inner wall of the outer shift ring is connected to the connecting rod.
[0009] The present invention is further configured such that the pushing auxiliary mechanism includes an outer rotating ring, a spiral plate, a longitudinal moving ring, a spiral ring, and a spiral groove. The outer rotating ring is rotatably mounted on the outer wall of the clamping tube. The spiral plate is mounted on one end of the outer rotating ring, and the spiral ring is mounted on one end of the longitudinal moving ring. The spiral groove is provided on the spiral ring. The spiral plate and the spiral groove are slidably connected. The rotation of the outer rotating ring can drive the rotating plate to rotate. The rotating spiral plate drives the longitudinal moving ring to move longitudinally, so that the outer moving ring and the connecting rod drive the inner pushing ring to push the inclined block to move.
[0010] The present invention is further configured such that a charging head assembly is installed at one end of the mating line, and a plug is installed at one end of the charging head assembly, so that users can easily perform charging operations without worrying about poor connection between the plug and the charging port or difficulty in plugging and unplugging.
[0011] The present invention is further configured such that a longitudinal groove is provided on the side wall of the clamping tube, and the connecting rod is slidably guided in the longitudinal groove. The design of the longitudinal groove can reduce the frictional resistance of the connecting rod, improve its sliding stability, and ensure that the pushing mechanism can work more smoothly.
[0012] The present invention is further configured such that a limiting ring is installed on the outer wall of the clamping tube, and the top and bottom ends of the outer moving ring are in contact with the limiting ring to limit the movement of the outer moving ring, thereby preventing excessive movement of the outer moving ring and ensuring that each component of the system maintains the correct position during operation.
[0013] The present invention is further configured such that the inclined block is provided with an inclined rail, and the inclined block is provided with a sliding guide on the inclined rail, which can realize the precise movement of the inclined block, ensure that the docking angle and position are accurate during the pushing process, and improve the efficiency and stability of the connection.
[0014] The present invention is further configured such that the inner push rings are arranged oppositely, and the inner push rings push the symmetrical inclined blocks to move relative to each other. The symmetrical design ensures that the force applied to the inclined blocks is uniform, thereby ensuring that the connection is more stable and reliable, avoiding possible offset and uneven pressure, and enhancing the tightness of the connection.
[0015] The present invention is further configured such that one end of the connecting line is connected to a charging cable, and the pushing and tightening mechanism connects the charging cable and the charging head assembly to avoid loose connection or poor contact, thereby improving the safety and stability of the charging process.

[0018] This utility model is equipped with a cable connection mechanism. Through the mutual cooperation of the mating block, mating hole and mating wire, a tight connection between the cable and the charging head is ensured, avoiding loosening or poor contact. The side push ring design provides convenient operating space, making the connection and disassembly process simpler and faster.
[0019] This utility model is equipped with a push-tightening mechanism. The cooperation of components such as clamping tube, tilting block, and slant block enables automatic tightening when the user inserts the cable through the push spring frame and inner push ring, making the contact between the connecting wire and the mating wire tighter and ensuring stable current transmission. The inner push ring pushes the symmetrical slant blocks to move relative to each other, ensuring that the force applied to the joint is evenly distributed, thereby enhancing the stability and tightness of the connection.
[0020] This utility model is equipped with a pushing auxiliary mechanism. The design of the outer rotating ring and the spiral plate enables the rotation to drive the longitudinal moving ring to move longitudinally, thereby pushing the inner pushing ring and the inclined moving block to move, assisting the smooth progress of the connection process.

[0030] Please see Figures 1-5A new energy vehicle charging cable includes a cable connection mechanism, a push-tightening mechanism, and a push-auxiliary mechanism. The cable connection mechanism includes a connecting wire 1, a mating wire 2, a mating hole 3, a mating block 4, and a side push ring 5. The mating hole 3 is located at one end of the mating wire 2, and the mating block 4 is installed at one end of the connecting wire 1, engaging with the mating hole 3. The side push ring 5 is located on the side wall of the connecting wire 1 and the mating wire 2. The push-tightening mechanism connects the connecting wire 1 and the mating wire 2. The push-tightening mechanism includes a clamping tube 6, an inclined block 7, a tilting block 8, a push spring frame 9, an inner push ring 10, a connecting rod 11, and an outer... The shifting ring 12 and multiple sets of inclined blocks 7 are symmetrically installed on the inner wall of the clamping tube 6. The inclined shifting block 8 is slidably connected to the inclined block 7. The push spring frame 9 is installed on the side of the inclined shifting block 8. The push spring frame 9 can press against the side of the mating line 2 and the connecting line 1, and the top end of the push spring frame 9 pushes against the side push ring 5, so that the connecting line 1 and the mating line 2 are relatively tightly connected. The inner push ring 10 moves directionally inside the clamping tube 6. The inner push ring 10 and the inclined shifting block 8 are slidably connected. The connecting rod 11 slides longitudinally on the clamping tube 6. The outer shifting ring 12 slides longitudinally on the outer wall of the clamping tube 6. The inner wall of the outer shifting ring 12 is connected to the connecting rod 11.
[0031] In this embodiment, the cable connection mechanism realizes a reliable connection between the charging cable 23 and the charging head. The mating block 4 at the end of the connecting line 1 and the mating hole 3 at the end of the mating line 2 form a preliminary docking. The side push rings 5 on both sides are set on the side walls of the connecting line 1 and the mating line 2 to provide force points for pushing and tightening. The charging head assembly 18 is connected to the plug 19 through the mating line 2 to ensure circuit conduction and ensure accurate positioning and reliable connection during the connection process. The inclined blocks 7 symmetrically installed on the inner wall of the clamping tube 6 are provided with inclined rails 22. The inclined blocks 8 slide on the inclined rails 22. The inner push ring 10 moves directionally within the clamping tube 6, pushing the symmetrical inclined blocks 8 to move relative to each other. The push spring frame 9 is installed on the side of the inclined blocks 8 and can press against the side of the mating line 2 and the connecting line 1. It achieves tightening by contacting the side push ring 5 at the top. The connecting rod 11 slides within the longitudinal groove 20 of the clamping tube 6 and cooperates with the outer moving ring 12 to transmit the pushing force and achieve overall synchronous movement.
[0032] The driving auxiliary mechanism includes an outer rotating ring 13, a spiral plate 14, a longitudinal moving ring 15, a spiral ring 16, and a spiral groove 17. The outer rotating ring 13 is rotatably mounted on the outer wall of the clamping tube 6. The spiral plate 14 is mounted on one end of the outer rotating ring 13, and the spiral ring 16 is mounted on one end of the longitudinal moving ring 15. The spiral groove 17 is provided on the spiral ring 16. The spiral plate 14 and the spiral groove 17 are slidably connected. The rotation of the outer rotating ring 13 can drive the rotating plate to rotate. The rotating spiral plate 14 drives the longitudinal moving ring 15 to move longitudinally, so that the outer moving ring 12 and the connecting rod 11 drive the inner pushing ring 10 to push the inclined block 8 to move.
[0033] In this embodiment, the outer rotating ring 13 is limited to rotating on the outer wall of the clamping tube 6. The spiral plate 14 at its end is engaged with the spiral groove 17 of the spiral ring 16 on the longitudinal moving ring 15. By rotating the outer rotating ring 13, the spiral plate 14 moves in the spiral groove 17, driving the longitudinal moving ring 15 to move longitudinally. This movement is transmitted to the inner pushing ring 10 through the outer moving ring 12 and the connecting rod 11, ultimately achieving precise control of the inclined block 8. The limiting ring 21 ensures that the movement range of the outer moving ring 12 is controlled.
[0034] Please see Figures 1-5 As a supplementary embodiment of a new energy vehicle charging cable for the cable connection mechanism, the push-tightening mechanism, and the push-auxiliary mechanism: A charging head assembly 18 is installed at one end of the mating line 2, and a plug 19 is installed at one end of the charging head assembly 18. A longitudinal groove 20 is opened on the side wall of the clamping tube 6, and the connecting rod 11 is slidably guided in the longitudinal groove 20. A limiting ring 21 is installed on the outer wall of the clamping tube 6, and the top and bottom ends of the outer moving ring 12 are in contact with the limiting ring 21 for restriction. An inclined block 7 is provided with an inclined rail 22, and the inclined moving block 8 is slidably guided on the inclined rail 22. The inner push ring 10 is arranged opposite to the symmetrical inclined moving block 8 and pushes the symmetrical inclined moving block 8 to move relative to each other. A charging cable 23 is connected to one end of the connecting line 1, and the push-tightening mechanism connects the charging cable 23 and the charging head assembly 18.
[0035] More specifically, firstly, the mating block 4 is connected to the mating hole 3 through the cable connection mechanism, completing the initial connection of the cable. The connecting line 1 and the mating line 2 are fixedly connected in this way. Next, the push tightening mechanism, through the cooperation of components such as the outer moving ring 12, the connecting rod 11, and the inner push ring 10, tightly connects the connecting line 1 and the mating line 2 together. This process is achieved by the pressure of the push spring frame 9 and the sliding of the inclined block 8. During the push tightening process, the outer rotating ring 13 and the spiral structure of the push auxiliary mechanism play an auxiliary role. By rotating and pushing the longitudinal movement of the connecting rod 11 and the outer moving ring 12, the inner push ring 10 pushes the inclined block 8, making the connection more secure. Finally, the contact between the connecting line 1 and the mating line 2 becomes tighter, and the connection of the charging cable is completed. At this time, the current transmission path is stable and not easy to loosen, ensuring the electrical safety and stability during the charging process.
[0036] In summary, during the use or operation of the overall equipment: when the cable connection mechanism is required to operate, the cable connection mechanism realizes a reliable connection between the charging cable 23 and the charging head. The mating block 4 at the end of the connecting line 1 and the mating hole 3 at the end of the mating line 2 form a preliminary docking. The side push rings 5 on both sides are set on the side walls of the connecting line 1 and the mating line 2 to provide force points for pushing and tightening. The charging head assembly 18 is connected to the plug 19 through the mating line 2 to ensure circuit conduction and ensure accurate positioning and reliable connection during the connection process.
[0037] When the clamping mechanism needs to be driven to run, the inclined blocks 7 symmetrically installed on the inner wall of the clamping tube 6 are provided with inclined rails 22. The inclined blocks 8 slide on the inclined rails 22. The inner push ring 10 moves in a direction within the clamping tube 6, pushing the symmetrical inclined blocks 8 to move relative to each other. The push spring frame 9 is installed on the side of the inclined blocks 8, which can press against the side of the mating line 2 and the connecting line 1, and achieves clamping by contacting the side push ring 5 at the top. The connecting rod 11 slides in the longitudinal groove 20 of the clamping tube 6, and cooperates with the outer moving ring 12 to transmit the driving force and achieve overall synchronous movement.
[0038] When the auxiliary mechanism needs to be driven to run, the outer rotating ring 13 is limited to rotating on the outer wall of the clamping tube 6. The spiral plate 14 at its end cooperates with the spiral groove 17 of the spiral ring 16 on the longitudinal moving ring 15. By rotating the outer rotating ring 13, the spiral plate 14 moves in the spiral groove 17, driving the longitudinal moving ring 15 to move longitudinally. This movement is transmitted to the inner pushing ring 10 through the outer moving ring 12 and the connecting rod 11, ultimately achieving precise control of the inclined block 8. The limiting ring 21 ensures that the movement range of the outer moving ring 12 is controlled.
[0039] First, the mating block 4 is connected to the mating hole 3 through the cable connection mechanism, completing the initial connection of the cable. The connecting line 1 and the mating line 2 are fixedly connected in this way. Next, the push tightening mechanism, through the cooperation of components such as the outer moving ring 12, the connecting rod 11, and the inner push ring 10, tightly connects the connecting line 1 and the mating line 2 together. This process is achieved by the pressure of the push spring frame 9 and the sliding of the inclined block 8. During the push tightening process, the outer rotating ring 13 and the spiral structure of the push auxiliary mechanism play an auxiliary role. By rotating and pushing the longitudinal movement of the connecting rod 11 and the outer moving ring 12, the inner push ring 10 pushes the inclined block 8, making the connection more secure. Finally, the contact between the connecting line 1 and the mating line 2 becomes tighter, and the connection of the charging cable is completed. At this time, the current transmission path is stable and not easy to loosen, ensuring the electrical safety and stability during the charging process.
[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
