Description

Technical Field

[0001] This utility model relates to the field of charging pile technology for new energy vehicles, specifically to a cable fixing structure and a charging pile. Background Technology

[0002] With the widespread use of new energy vehicles, the demand for charging stations has also increased significantly. Currently, electric vehicle charging stations are mainly divided into floor-mounted and wall-mounted types. Regardless of whether they are floor-mounted or wall-mounted, because there is a certain distance between the charging station and the electric vehicle that needs to be charged, a relatively long charging cable is required to meet the needs.

[0003] Currently, the charging cable of a charging station extends from the front panel of the charging station itself, with the charging head connected to the end of the cable. When charging is needed, the user holds the charging head and pulls the charging cable to connect it to the vehicle. However, because the charging cables of charging stations are generally large in diameter and heavy, and are often pulled during use, they frequently become loose or detach over time. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a cable fixing structure for auxiliary fixing of the charging cable of the charging pile, so as to prevent the charging cable from becoming loose or falling off.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable fixing structure, comprising:

[0006] The base is detachably fixed to the outer shell of the charging station;

[0007] A connector is provided on the base;

[0008] The mounting sleeve is rotatably connected to the base via the connector, and the mounting sleeve can be fixed to the base via the connector. The inner diameter of the mounting sleeve is larger than the outer diameter of the charging cable.

[0009] Multiple clamping plates are provided, and these clamping plates are circumferentially spaced around the central axis of the mounting sleeve; and

[0010] A drive structure, disposed on the mounting sleeve and connected to all the clamping plates, is capable of driving all the clamping plates to move simultaneously along the radial direction of the mounting sleeve toward the central axis to clamp the charging cable passing through the mounting sleeve.

[0011] Furthermore, the driving structure includes a rotary drive source, a drive disk, a guide disk, a push rod, and a locking element. The drive disk is rotatably and coaxially mounted on the mounting sleeve. The rotary drive source is connected to the drive disk and can drive the drive disk to rotate around its center. The drive disk has multiple arc-shaped guide grooves, which are evenly spaced circumferentially. The guide disk is fixed to the mounting sleeve and stacked on top of the drive disk. The guide disk has multiple sliding grooves spaced radially and circumferentially, with each sliding groove corresponding to one of the arc-shaped guide grooves. An internal push rod is provided, which can slide along the slide groove. Each push rod has an insertion rod at its bottom, which passes through the slide groove and inserts into the arc-shaped guide groove. The insertion rod can slide within the arc-shaped guide groove. When the drive disk rotates, it can push the push rod to slide within the slide groove through the insertion rod, the slide groove, and the arc-shaped guide groove. A clamping plate is fixed to the inner end of each push rod. The rotation drive source is connected to the drive disk and can drive the drive disk to rotate. The locking member is provided on the mounting sleeve for locking the drive disk onto the mounting sleeve.

[0012] Furthermore, the rotary drive source includes a lever, and the side wall of the mounting sleeve has an annular notch communicating with its inner cavity. The lever is disposed on the drive disk and passes through the annular notch radially outward along the drive disk.

[0013] Furthermore, the locking component includes a tightening rod and a pressure plate. The side wall of the mounting sleeve has a T-shaped mounting hole communicating with its inner cavity, and the large end of the T-shaped mounting hole is located near the center. The tightening rod is inserted into the T-shaped mounting hole from the outside of the mounting sleeve, and the tightening rod is threadedly connected to the small end of the T-shaped mounting hole. The pressure plate is located in the large end of the T-shaped mounting hole and is connected to the end of the tightening rod. Rotating the tightening rod can drive the pressure plate to press against the drive disc.

[0014] Furthermore, the connector includes two connecting rods and a locking nut. The two connecting rods are arranged opposite to each other, and one end of the connecting rod is connected to the mounting sleeve, while the other end is hinged to the base via a hinge shaft. A locking nut is provided at the end of the hinge shaft. By rotating the locking nut, the locking nut can press the connecting rod onto the base.

[0015] Furthermore, the clamping plate is an arc-shaped plate.

[0016] Furthermore, an anti-slip pad is provided on the contact surface between the clamping plate and the charging cable.

[0017] A charging pile includes the aforementioned cable fixing structure, which is fixed to the outer casing of the charging pile.

[0018] The beneficial effects of this utility model are:

[0019] During installation of the aforementioned cable fixing structure and charging pile, the charging cable is passed through the center of the mounting sleeve and into the outer shell of the charging pile before being fixed to the charging pile body, completing the first fixing of the charging cable. After the outer shell of the charging pile is installed and fixed, the base is fixed to the outer shell of the charging pile. Then, according to the direction of the charging cable, the angle of the mounting sleeve is adjusted so that the direction of the mounting sleeve follows the exit direction of the charging cable. Next, the angle and position of the mounting sleeve are locked and fixed by the connectors; finally, the driving structure drives all the clamping plates to clamp the charging cable outer shell, thus completing the second fixing of the charging cable.

[0020] This cable fixing structure provides a second clamp to secure the charging cable outside the casing, preventing it from loosening or detaching during charging due to pulling or swinging. Furthermore, the adjustable angle of the mounting sleeve allows for uninterrupted cable routing, reducing bending and extending the lifespan of the charging cable in the charging station.

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0031] Please see Figures 1 to 5 This utility model provides a cable fixing structure, including a base 100, a connector 200, a mounting sleeve 300, a clamping plate 400, and a driving structure 500.

[0032] Specifically, the base 100 is detachably fixed to the outer shell 1 of the charging pile. The connection method can be by bolt fixing, snap-fit ​​fixing, or suction cup fixing.

[0033] The connector 200 is mounted on the base 100. The mounting sleeve 300 is rotatably connected to the base 100 via the connector 200, and the connector 200 can also fix the base 100 on the base 100. The inner diameter of the mounting sleeve 300 is larger than the outer diameter of the charging cable 2. There are multiple clamping plates 400, which are circumferentially spaced around the central axis of the mounting sleeve 300.

[0034] The drive structure 500 is mounted on the mounting sleeve 300 and connected to all the clamping plates 400. It can drive all the clamping plates 400 to move simultaneously along the radial direction of the mounting sleeve 300 toward the central axis to clamp the charging cable 2 passing through the mounting sleeve 300.

[0035] During installation, the charging cable 2 is passed through the center of the mounting sleeve 300, inserted into the outer shell 1 of the charging pile, and then fixed to the body of the charging pile, completing the first fixing of the charging cable 2. After the outer shell 1 of the charging pile is installed and fixed, the base 100 is fixed to the outer shell 1 of the charging pile. Then, according to the direction of the charging cable 2, the angle of the mounting sleeve 300 is adjusted so that the direction of the mounting sleeve 300 follows the exit direction of the charging cable 2. Next, the angle and position of the mounting sleeve 300 are locked and fixed by the connector 200. Then, the drive structure 500 drives all the clamping plates 400 to clamp the charging cable 2 onto the outer shell 1, thus completing the second fixing of the charging cable 2.

[0036] This cable fixing structure allows for a second clamping fixation of the charging cable 2 outside the housing 1, preventing it from loosening or detaching during charging due to pulling or swinging. Furthermore, since the angle of the mounting sleeve 300 is adjustable, the original outlet direction of the charging cable 2 remains unchanged, reducing bending and extending its lifespan.

[0037] Specifically, the drive structure 500 includes a rotary drive source 510, a drive disk 520, a guide disk 530, a push rod 540, and a locking element 550. The drive disk 520 is rotatable and coaxially mounted on the mounting sleeve 300. The rotary drive source 510 is connected to the drive disk 520 and can drive the drive disk 520 to rotate around its center. The drive disk 520 has multiple arc-shaped guide grooves, which are evenly spaced circumferentially. The guide disk 530 is fixed to the mounting sleeve 300 and stacked on top of the drive disk 520. The guide disk 530 has multiple sliding grooves spaced radially and circumferentially, and the sliding grooves correspond one-to-one with the arc-shaped guide grooves. Each sliding groove contains a push rod 540, which can slide along the sliding groove. Each push rod 540 has a insertion rod 560 at its bottom. The insertion rod 560 passes through a sliding groove and inserts into an arc-shaped guide groove, and can slide within the arc-shaped guide groove. When the drive disc 520 rotates, it can push the push rod 540 to slide within the sliding groove through the insertion rod 560, the sliding groove, and the arc-shaped guide groove. A clamping plate 400 is fixed to the inner end of each push rod 540. A rotation drive source 510 is connected to the drive disc 520 and can drive the drive disc 520 to rotate. A locking member 550 is provided on the mounting sleeve 300 to lock the drive disc 520 onto the mounting sleeve 300.

[0038] In use, with the locking element 550 released, the drive disk 520 is driven to rotate clockwise by the rotation drive source 510. Under the action of the insertion rod 560, the slide groove and the arc-shaped guide groove, all the clamping plates 400 are driven to move towards the center, which can clamp the charging cable 2. Then the locking element 550 is locked.

[0039] In this embodiment, the rotary drive source 510 includes a lever. The side wall of the mounting sleeve 300 has an annular notch communicating with its inner cavity. The lever is mounted on the drive disk 520 and passes through the annular notch radially outward along the drive disk 520. In use, with the locking member 550 released, simply moving the lever will drive the drive disk 520 to rotate. Of course, in other embodiments, the rotary drive source 510 can also be other types, such as a rotary motor, or a type that engages with other rotary actuators.

[0040] In this embodiment, the locking member 550 includes a tightening rod and a pressure plate. The side wall of the mounting sleeve 300 has a T-shaped mounting hole communicating with its inner cavity, with the larger end of the T-shaped mounting hole located near the center. The tightening rod is inserted into the T-shaped mounting hole from the outside of the mounting sleeve 300, and the tightening rod is threadedly connected to the smaller end of the T-shaped mounting hole. The pressure plate is located inside the larger end of the T-shaped mounting hole and is connected to the end of the tightening rod. Rotating the tightening rod drives the pressure plate to press against the drive disc 520.

[0041] When in use, rotating the clamping rod in the forward or reverse direction will drive the pressure plate to move inward or outward, and the drive disc 520 can be used to lock or release it.

[0042] In this embodiment, the connector 200 includes two connecting rods and a locking nut. The two connecting rods are arranged opposite each other, with one end connected to the mounting sleeve 300 and the other end hinged to the base 100 via a hinge shaft. A locking nut is provided at the end of the hinge shaft; rotating the locking nut presses the connecting rod against the base 100. In use, when the locking nut is loosened, the angle of the mounting sleeve 300 can be rotated to adjust it to the desired position, and then it can be locked.

[0043] Furthermore, in practical implementation, the clamping plate 400 can be set as an arc-shaped plate, which can further improve the fit between the clamping plate 400 and the charging cable 2, thereby increasing the clamping force. Additionally, an anti-slip pad can be provided on the contact surface between the clamping plate 400 and the charging cable 2, which can also increase the clamping force of the clamping plate 400.

[0044] This application also provides a charging pile, which includes the cable fixing structure as described in the claim, wherein the cable fixing structure is fixed to the outer shell of the charging pile.

[0045] How to use the above cable fixing structure:

[0046] The aforementioned cable fixing structure allows for a second clamping fixation of the charging cable 2 outside the housing 1, preventing it from loosening or detaching during charging due to pulling. Furthermore, since the angle of the mounting sleeve 300 is adjustable, the original orientation of the charging cable 2 remains unchanged, reducing bending and extending its lifespan.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
