Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and more specifically, to a charging pile cable tensioning and guiding device. Background Technology

[0002] With the rapid development of the new energy vehicle industry, charging piles have become widely used as an important supporting infrastructure. During the use of charging piles, the charging cable (hereinafter referred to as the cable) is a key component connecting the charging pile and the vehicle, and its ease of operation directly affects the user's charging experience. Because high-power charging piles use thicker wires to meet the demands of high current transmission, the cables are generally quite heavy. To avoid problems such as wear, tangling, and vehicle damage caused by the cable dragging on the ground, existing technologies often install cable guiding devices on the top of the charging pile, suspending the cable in the air to reduce its weight and friction with the ground.

[0003] Currently, charging cable guide devices installed on top of charging piles are mainly divided into two types: fixed and folding extension types. Fixed guide devices have a relatively fixed installation position and guiding range, making it impossible to flexibly adjust the extension distance and direction of the charging cable according to changes in the vehicle's parking position, thus limiting the guiding range. Some devices with folding extension capabilities use a folding arm structure, expanding the coverage area of ​​the charging cable through the unfolding of multiple swing arms. However, these folding extension devices still have significant shortcomings in practical use: on the one hand, unfolding and retracting the folding arm usually requires manual operation, requiring the user to overcome both the weight of the charging cable itself and the joint resistance of the folding arm to complete the stretching; on the other hand, some devices using spring balancers for assistance generate greater rebound force as the charging cable stretches further, making it more difficult for the user to pull the cable. Furthermore, when using a spring balancer alone, excessively long charging cables will still rub against the ground, affecting their lifespan.

[0004] In summary, existing charging pile cable guiding devices have the following problems: fixed devices have limited guiding range and cannot adapt to the charging needs of different parking locations; although folding extension devices expand the coverage area, manual extension requires overcoming the weight of the cable and joint resistance, making operation laborious and inconvenient. At the same time, some assistive devices have the defect that the resistance increases with the extension distance. Therefore, in order to address this problem, this application provides a charging pile cable extension guiding device to meet the requirements. Summary of the Invention

[0005] To address the technical problem that existing guiding devices capable of expanding the guiding range of charging cables are not convenient to operate and require a large pulling force to achieve the expansion of the guiding range, this invention provides a charging cable tensioning and guiding device for charging piles.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A charging pile gun wire stretching guide device includes a charging pile body, a charging gun is inserted into one side of the charging pile body, a gun wire is fixedly arranged between the charging pile body and the charging gun, and a guide component for guiding the stretching of the gun wire is provided on the top of the charging pile body. The guide component consists of a fixing component and a transmission component. The fixing component includes a fixing base set on the top of the charging pile body, a movable bushing rotatably connected to the outer side of the fixing base, and a connecting housing fixedly connected to the outer side of the movable bushing. The mounting components enable the device to connect with various types of charging stations, allowing conventional charging stations to guide the extension of the charging cable.

[0007] The transmission assembly includes a connecting shaft fixedly connected to the inner wall of the connecting housing. A transmission guide plate for extending the guiding range of the gun line is rotatably connected to the outer side of the connecting shaft. A movable guide rail for guiding the gun line is provided at the bottom of the transmission guide plate. An adjusting rotating column for flexibly moving the gun line is slidably provided on the inner side of the movable guide rail.

[0008] The transmission component can extend the guiding range by the weight of the gun wire itself, thus requiring less manual effort from the user and ensuring ease of use, meeting the needs of convenient operation.

[0009] In the above technical solution, a first limiting block and a second limiting block are fixedly connected to the top of the transmission guide plate, and the first limiting block and the second limiting block are respectively arranged on both sides of the connecting shaft column.

[0010] In the above technical solution, one end of the movable guide rail is fixedly connected to a single column support, and the inner side of the single column support is rotatably connected to a first rotating column. The first rotating column is slidably connected to the top of the transmission guide plate, and the first rotating column is arranged in an abutting position with the second limiting block.

[0011] In the above technical solution, the end of the movable guide rail away from the single column support is fixedly connected to a combined support, and the inner side of the combined support is rotatably connected to two second rotating columns, both of which are slidably connected to the top of the transmission guide plate.

[0012] In the above technical solution, the transmission guide plate is further provided with an arc-shaped positioning end fixedly connected to one end near the second rotating column, and a lower positioning block and an upper positioning block are fixedly connected to the inner wall of the connecting housing. The lower positioning block and the upper positioning block are located at the bottom and top of the arc-shaped positioning end, respectively.

[0013] In the above technical solution, a sleeve is further provided on the outer side of the adjusting column, and a connecting base plate is fixedly connected to the bottom of the sleeve. The connecting base plate is slidably connected to the bottom of the movable guide rail.

[0014] In the above technical solution, further, a limiting collar is rotatably connected to the bottom of the connecting base plate, and the limiting collar is sleeved on the outside of the gun wire.

[0015] In the above technical solution, furthermore, a plurality of fixing bolts are inserted into the bottom of the fixing base, and the plurality of fixing bolts are threadedly connected to the charging pile body.

[0016] The technical effects and advantages of this invention are as follows: 1. By setting up a transmission component, the movable guide rail can slide at the bottom of the transmission guide plate and extend from the inside of the connecting housing, which can further extend the guiding range of the gun wire. Users can flexibly adjust the extension distance and direction of the gun wire according to the change of the vehicle parking position. Moreover, the extension of the guide rail to extend the guiding range is achieved by the weight of the gun wire itself, so that the movable guide rail can be extended without manual intervention, thus ensuring the convenience of use and meeting the needs of actual use. 2. By setting a fixing component, this invention can be installed on charging piles that do not have a gun wire guiding device, thereby enabling such conventional charging piles to have gun wire stretching and guiding capabilities. Moreover, this device is manufactured independently, which is different from the integrated production of existing charging piles with gun wire guiding capabilities, effectively reducing production costs and production difficulty.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Refer to the instruction manual appendix Figures 1-6 As shown, an embodiment of the present invention provides a charging pile gun wire stretching guide device, which includes a charging pile body 1, a charging gun 2 inserted into one side of the charging pile body 1, a gun wire 3 fixedly disposed between the charging pile body 1 and the charging gun 2, and a guide component for guiding the stretching of the gun wire 3 disposed on the top of the charging pile body 1. The guide component consists of a fixing component and a transmission component.

[0021] The fixing component includes a fixing seat 4 set on the top of the charging pile body 1. A movable bushing 5 is rotatably connected to the outside of the fixing seat 4. A connecting housing 7 is fixedly connected to the outside of the movable bushing 5. Multiple fixing bolts 6 are inserted into the bottom of the fixing seat 4. The multiple fixing bolts 6 are threadedly connected to the charging pile body 1.

[0022] It should be noted that the guide component is fixedly connected to the charging pile body 1 by multiple fixing bolts 6. This installation method can be adapted to various types of charging piles. This device can be installed on charging piles that do not have a gun line guide device, thereby enabling such conventional charging piles to have gun line stretching and guiding capabilities. Moreover, this device is manufactured independently, which is different from the existing integrated production of charging piles with gun line guiding capabilities, effectively reducing production costs and production difficulty.

[0023] The rotatable design of the movable bushing 5 enables the connecting housing 7 to have circumferential displacement, thereby allowing the gun wire 3 to be guided in a fan shape when guiding the gun wire 3, thus improving the flexibility and range of guiding the gun wire 3.

[0024] Furthermore, the transmission assembly includes a connecting shaft 8 fixedly connected to the inner wall of the connecting housing 7, a transmission guide plate 9 rotatably connected to the outer side of the connecting shaft 8 for extending the guiding range of the gun wire 3, a movable guide rail 12 for guiding the gun wire 3 provided at the bottom of the transmission guide plate 9, and an adjusting rotating column 20 slidably provided on the inner side of the movable guide rail 12 to allow the gun wire 3 to move flexibly.

[0025] A first limiting block 10 and a second limiting block 11 are fixedly connected to the top of the transmission guide plate 9. The first limiting block 10 and the second limiting block 11 are both set with equal arc contours. The first limiting block 10 and the second limiting block 11 are respectively set on both sides of the connecting shaft column 8. A single column support 13 is fixedly connected to one end of the movable guide rail 12. A first rotating column 14 is rotatably connected to the inner side of the single column support 13. The first rotating column 14 is slidably connected to the top of the transmission guide plate 9. The first rotating column 14 and the second limiting block 11 are set in an abutting position. A combined support 15 is fixedly connected to the end of the movable guide rail 12 away from the single column support 13. Two second rotating columns 16 are rotatably connected to the inner side of the combined support 15. Both second rotating columns 16 are slidably connected to the top of the transmission guide plate 9.

[0026] The movable guide rail 12 rotates on the top of the transmission guide plate 9 via the first rotating post 14 and the two second rotating posts 16, thereby enabling the movable guide rail 12 to slide at the bottom of the transmission guide plate 9. The two second rotating posts 16 are configured so that when the first rotating post 14 disengages from the top of the transmission guide plate 9, the movable guide rail 12 contacts the transmission guide plate 9 via the two second rotating posts 16, so that the movable guide rail 12 can still remain in a horizontal state and will not flip over.

[0027] An arc-shaped positioning end 17 is fixedly connected to one end of the transmission guide plate 9 near the second rotating column 16. A lower positioning block 18 and an upper positioning block 19 are fixedly connected to the inner wall of the connecting housing 7. The lower positioning block 18 and the upper positioning block 19 are located at the bottom and top of the arc-shaped positioning end 17, respectively.

[0028] The rotation angle of the transmission guide plate 9 is limited by the lower positioning block 18 and the upper positioning block 19. After the transmission guide plate 9 rotates and comes into contact with the lower positioning block 18 or the upper positioning block 19, the transmission guide plate 9 stops rotating.

[0029] A sleeve 21 is fitted onto the outer side of the adjusting column 20. A connecting base plate 22 is fixedly connected to the bottom of the sleeve 21. The connecting base plate 22 is slidably connected to the bottom of the movable guide rail 12. A limiting collar 23 is rotatably connected to the bottom of the connecting base plate 22. The limiting collar 23 is an elastic structure made of metal. A notch is opened on the lower side of the limiting collar 23, which allows the limiting collar 23 to be elastically stretched. The elastic stretching of the limiting collar 23 allows the gun wire 3 to enter the inner side of the limiting collar 23. The limiting collar 23 is fitted onto the outer side of the gun wire 3. The rotatable setting of the limiting collar 23 can improve the flexibility of the gun wire 3 and avoid the problem of the gun wire 3 twisting due to the limiting collar 23 when guiding the gun wire 3.

[0030] It should be noted that, in this process, the charging cable 3 is lifted by the limiting collar 23, which solves the problem of the charging cable 3 falling to the ground, and transfers most of the weight of the charging cable 3 to the limiting collar 23, reducing the manpower required for manual pulling. The movement of the charging cable 3 is as follows: when holding the charging gun 2 and pulling the charging cable 3, the connecting housing 7 can rotate under the action of the movable bushing 5, so that the orientation of the charging cable 3 can follow the desired direction. At the same time, by adjusting the setting of the rotating column 20, the resistance of the connecting base plate 22 during movement can be reduced, thereby enabling the limiting collar 23 to drive the charging cable 3 to move, thus guiding the charging cable 3.

[0031] When the connecting base plate 22 moves to the end of the movable guide rail 12, the movable guide rail 12 can guide the gun wire 3 to its maximum distance. However, since the gun wire 3 is located at the end of the transmission guide plate 9 near the second limit block 11, the transmission guide plate 9 flips under the influence of the weight of the gun wire 3, causing the end of the transmission guide plate 9 near the second limit block 11 to tilt downwards. When the transmission guide plate 9 is in the tilted state, the movable guide rail 12 is affected by the weight of the gun wire 3. Under the rotation of the first rotating column 14 and the two second rotating columns 16, the movable guide rail 12 moves at the bottom of the transmission guide plate 9. The sliding motion allows the movable guide rail 12 to extend from the inside of the connecting housing 7 until the second rotating column 16 is blocked by the first limiting block 10. The extension of the movable guide rail 12 from the inside of the connecting housing 7 further extends the guiding range of the gun wire 3, allowing the user to flexibly adjust the extension distance and direction of the gun wire according to changes in the vehicle's parking position. Moreover, the extension of the guiding range by the movable guide rail 12 is achieved by the weight of the gun wire 3 itself, so that the movable guide rail 12 can be extended without manual intervention, thus ensuring ease of use and meeting the needs of actual use.

[0032] When the transmission guide plate 9 rotates, it drives the arc-shaped positioning end 17 to rise until it stops after being blocked by the upper positioning block 19. The upper positioning block 19 restricts the rotation angle of the transmission guide plate 9, ensuring that the transmission guide plate 9 is in a small-angle tilt state. This ensures that the movable guide rail 12 can slide out from the connecting housing 7. At the same time, when the gun wire 3 needs to move in the direction of the arc-shaped positioning end 17, the adjusting column 20 will not generate much resistance due to the uphill movement because the transmission guide plate 9 is in a small-angle tilt. This avoids the need for more manpower when resetting the movable guide rail 12.

[0033] When the charging gun 2 is finished and the charging cable 3 is reset, the adjusting column 20 moves in the opposite direction. When it moves to the other end, the connecting base plate 22 is located on the side of the connecting shaft column 8 near the first limiting block 10. Under the influence of the weight of the charging cable 3, the transmission guide plate 9 rotates in the opposite direction until the arc-shaped positioning end 17 is blocked by the lower positioning block 18 and stops. This allows the movable guide rail 12 to slide in the opposite direction under the inclination of the transmission guide plate 9 and enter the inner side of the connecting housing 7, completing one cycle of the device. In actual use, the above operation can be repeated for reuse.
