Description

Technical Field

[0001] The utility model relates to the technical field of charging pile cable recovery, in particular to a vertical spring cable recovery device for a charging pile. Background Art

[0002] With the popularity of electric vehicles, the construction and improvement of charging facilities has become an important issue. In the process of electric vehicle charging, cable management and recycling has become a key issue. In traditional charging methods, cables are often placed or dragged randomly, which not only affects the charging efficiency, but also may cause safety hazards. Therefore, it is particularly important to design an efficient and safe cable support and return structure.

[0003] Most existing cable support structures use simple hooks or fixed brackets. Although these designs solve the problem of cable placement to a certain extent, they are obviously insufficient in cable recycling and arrangement. Users are required to drag the charging cable while holding the charging gun. Since the charging cable of electric vehicles is thicker in diameter, the cable is heavier, which consumes more physical strength of the user. In the process of dragging the cable, it is easy for the cable to rub against the ground, causing the cable to be worn or even damaged.

[0004] In summary, the cable support and return structure for charging electric vehicles is an important component of electric vehicle charging facilities. Designing an efficient and safe cable support and return structure is of great significance for improving charging efficiency, reducing operation difficulty and ensuring safety. In order to solve the above problems, the utility model proposes a vertical spring cable recovery device for charging piles. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vertical spring cable recovery device for a charging pile, comprising an assembly base and a compression spring, the bottom end limit of the compression spring is installed inside the assembly base, the top end of the compression spring is fixedly connected to a connecting seat, the upper end surface of the connecting seat is integrally formed with a pull rod, the end of the pull rod facing away from the connecting seat is fixedly connected to a fixed seat, the upper limit position of the fixed seat is rotatably mounted with a first arc-shaped clamp, the upper limit position of the first arc-shaped clamp is connected to a second arc-shaped clamp, and the charging cable limit is arranged between the first arc-shaped clamp and the second arc-shaped clamp.

[0007] The utility model is further configured that a plug hole is opened on the assembly base, a plug rod is welded to the bottom end of the compression spring, and the plug rod is plugged into the inside of the plug hole.

[0008] The utility model is further configured such that a connecting groove is provided on the assembly base at a position corresponding to the plug-in hole, a threaded hole is provided inside the assembly base at a position corresponding to the connecting groove, a first bolt is bolted in the threaded hole, and the plug-in hole and the connecting groove are tightened by the cooperation of the first bolt and the threaded hole.

[0012] The utility model is further configured such that both ends of the first arc-shaped clamping plate and the second arc-shaped clamping plate are bolted together by fourth bolts.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The vertical spring cable recovery device for the charging pile is provided with a compression spring and a pull rod. When the charging cable is pulled, the compression spring generates elastic deformation and then bends to support the charging cable, thereby avoiding the user from dragging the charging cable while moving the charging gun head. The user only needs to move the charging gun head, which saves the user's physical strength and facilitates the movement of the charging gun head.

[0015] 2. The charging pile uses a vertical spring cable recovery device. When the charging gun head is taken out for charging and put back into the charging pile, the compression spring and the pull rod support the charging cable, so that the charging cable is always off the ground, avoiding wear caused by friction between the charging cable and the ground, and increasing the service life of the charging cable.

[0016] 3. The charging pile uses a vertical spring cable recovery device. After charging is completed, the charging gun is pulled out of the charging port of the car, so that the charging cable no longer pulls the compression spring. The compression spring is used to restore the charging cable to its original state and drive the charging cable to return automatically. The charging cable is stored on the side wall of the charging pile, and then the charging gun head can be hung on the charging pile. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-5 The utility model provides a technical solution: a vertical spring cable recovery device for a charging pile, comprising an assembly base 1 and a compression spring 2. The assembly base 1 is fixedly mounted on the charging pile.

[0028] The bottom end of the compression spring 2 is limitedly installed inside the assembly base 1. Specifically, the assembly base 1 is provided with a plug hole 8, and a plug rod 9 is welded to the bottom end of the compression spring 2, and the plug rod 9 is plugged into the inside of the plug hole 8. A connecting groove 10 is provided at a position corresponding to the plug hole 8 on the assembly base 1, and a threaded hole 11 is provided inside the assembly base 1 at a position corresponding to the connecting groove 10. A first bolt 12 is bolted in the threaded hole 11, and the plug hole 8 and the connecting groove 10 are tightened by the cooperation of the first bolt 12 and the threaded hole 11. The assembly base 1 and the compression spring 2 are set to be detachably connected, which is convenient for later maintenance and repair.

[0029] The top end of the compression spring 2 is fixedly connected to a connecting seat 3 , the upper end surface of the connecting seat 3 is integrally provided with a pull rod 4 , and the end of the pull rod 4 away from the connecting seat 3 is fixedly connected to a fixing seat 5 .

[0030] In the embodiment of the utility model, an anti-collision block 13 is provided on the side wall of the fixing seat 5, and the anti-collision block 13 is bolted on the side wall of the fixing seat 5 by a second bolt 14. By providing the anti-collision block 13, a direct collision between the fixing seat 5 and the charging pile is avoided, the fixing seat 5 is protected, and the service life of the device is extended.

[0031] The fixing seat 5 is rotatably mounted with a first arc-shaped clamping plate 6 in the upper limit position. Specifically, a through hole is opened on the fixing seat 5, and a third bolt 15 is slidably inserted in the through hole. One end of the third bolt 15 is threadedly connected to the first arc-shaped clamping plate 6.

[0032] In the embodiment of the utility model: two washers 16 are sleeved on the outer side of the third bolt 15, and the two washers 16 are respectively located on both sides of the fixing seat 5. By providing the washers 16, the stability of the connection can be increased to prevent the third bolt 15 from loosening.

[0033] The upper limit of the first arc clamping plate 6 is connected to the second arc clamping plate 7, and both ends of the first arc clamping plate 6 and the second arc clamping plate 7 are bolted together by a fourth bolt 17. The charging cable limit is set between the first arc clamping plate 6 and the second arc clamping plate 7. By rotating the fourth bolt 17, the distance between the first arc clamping plate 6 and the second arc clamping plate 7 can be adjusted, thereby facilitating the clamping of charging cables of different calibers, thereby improving the applicability of the device.

[0034] Working principle:

[0035] When in use, the charging cable is inserted between the first arc-shaped clamping plate 6 and the second arc-shaped clamping plate 7. The first arc-shaped clamping plate 6 and the second arc-shaped clamping plate 7 are moved closer by rotating the fourth bolt 17 to tighten the charging cable. When the charging cable is pulled to charge, the charging cable is pulled and the first arc-shaped clamping plate 6 is driven to move.

[0036] When the threaded connection degree between the third bolt 15 and the first arc-shaped clamping plate 6 is high, the first arc-shaped clamping plate 6 is not easy to rotate on the side wall of the fixing seat 5, and then the first arc-shaped clamping plate 6 is limited and rotated on the side wall of the fixing seat 5 by rotating the third bolt 15. When the charging cable is pulled, the first arc-shaped clamping plate 6 and the second arc-shaped clamping plate 7 can rotate in the pulling direction of the charging cable, thereby improving the flexibility of the device when in use.

[0037] The charging cable is pulled, causing the compression spring 2 to produce elastic deformation and then bend, which supports the charging cable. Since the charging gun is plugged into the charging port of the car during charging, the charging cable continues to pull the compression spring 2, and the compression spring 2 remains in a deformed state. When charging is completed, the charging gun is pulled out of the charging port of the car, so that the charging cable no longer pulls the compression spring 2, and the compression spring 2 returns to its original state, driving the charging cable to automatically return to its original position, reducing the difficulty of operation.

[0038] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
