Description

Movable charging cable clamp Technical Field

[0001] This invention relates to a charging cable holder, and more particularly to a movable charging cable holder that provides axial rotational freedom through a ring structure, thereby achieving a mid-section support point for the charging cable. This effectively prevents the charging cable from being unable to straighten and becoming tangled in a circle, while also preventing damage to the charging cable and charging gun head. Background Technology

[0002] With the continuous development and progress of technology, the cars on the market have shifted from traditional gasoline vehicles to electric vehicles. As time goes on, the number of electric vehicles is also increasing. Because electric vehicles only need to charge their own batteries to start and drive, and the conversion of electrical energy does not produce pollution, they have a good environmental protection effect.

[0003] On the other hand, the charging process for electric vehicles requires the use of charging stations, and the number of charging stations on the market is constantly increasing, such as upright or wall-mounted charging stations. These types of charging stations often have long charging cables so that the charging gun can extend through the cable to the charging port of the electric vehicle for charging.

[0004] To prevent the charging cable from tangling and knotting on the ground when the user uses the charging gun, current charging machines include a cable clamp to hold the middle section of the cable for support. This clamp is connected to a counterweight via a rope, allowing the user to lift the charging gun with less effort. The current cable clamp primarily connects the charging cable using two semi-circular rubber rings secured by bolts on metal rings. The charging cable and the cable clamp cannot slide or rotate relative to each other. However, with this design, when the charging cable is stretched, a section near the cable clamp connection area cannot be straightened; the affected length depends on the original position of the pulley. Furthermore, even though the charging cable itself is flexible, it can still curl when stretched.

[0005] In view of this, it is necessary to provide a movable charging cable holder that provides rotational freedom in the axial direction through a ring structure, realizes the mid-section support point of the charging cable, effectively avoids the situation where the charging cable cannot be straightened and is tangled into a circle, avoids damage to the charging cable and charging gun head, and solves the defects of the known technology.

[0006] Summary of the Invention

[0007] The purpose of this invention is to provide a movable charging cable holder that provides rotational freedom in the direction of the central axis through a semi-circular bearing, an annular bearing, or a thin metal ring, thereby achieving a mid-section support point for the charging cable and effectively preventing the charging cable from being unable to straighten and becoming tangled in a circle, thus avoiding damage to the charging cable and charging gun head.

[0008] Another objective of this invention is to provide a movable charging cable holder. The combination of a clamping assembly and a pivot assembly provides the charging cable, which is secured by the clamping assembly, with rotational freedom along its central axis. The clamping assembly can be fixed to the outer circumference of various charging cables through the engagement of two fitting parts. Furthermore, when the hanging part of the pivot assembly is fixed at a height by a rope or connected to a pulley and counterweight, it provides a mid-section support point for the charging cable. Because the clamping assembly and the charging cable have rotational freedom along their central axis relative to the pivot assembly, when the user holds the charging gun and pulls the charging cable, the movable charging cable holder allows the clamping assembly and the charging cable to rotate along their central axis, preventing the charging cable from becoming tangled and coiled, thus solving the problem of the charging cable curling under stress. On the other hand, the rotation between the clamping assembly and the pivot assembly is achieved through a ring-shaped structure, such as a semi-circular bearing, a ring bearing, or a thin metal ring, resulting in a simplified overall structure that is easy to assemble and suitable for various types of charging cables. Furthermore, the hanging part of the pivot assembly is combined with the locking protrusion of the outer casing or outer ring sleeve for fixing with a bolt, which simplifies the installation of the lifting rope. Thus, the movable charging cable holder of this invention provides support for the charging cable while solving the problem of the charging cable not being able to be straightened and coiled, effectively avoiding situations that may damage the charging cable and charging gun head.

[0040] Figure 1 is a schematic diagram of the movable charging cable clamp according to the first embodiment of the present invention for clamping a charging cable. Figure 2 is a perspective view of the movable charging cable clamp according to the first embodiment of the present invention. Figure 3 is an exploded view of the movable charging cable clamp according to the first embodiment of the present invention. Figure 4 is a cross-sectional view of the movable charging cable clamp according to the first embodiment of the present invention. Referring to Figures 1 to 4, the present invention provides a movable charging cable clamp 1 to realize the middle support point of the charging cable 9 and provide the charging cable 9 with rotational freedom in the axial direction, avoiding the situation where the charging cable cannot be straightened and twisted into a circle. In this embodiment, the movable charging cable clamp 1 includes a clamping component 10 and a pivoting component 20. The clamping component 10 is assembled and fixed to an outer peripheral surface 90 of the charging cable 9 by clamping or fitting, wherein the clamping component 10 includes a first guide groove 13, which is recessed inward and surrounds an outer peripheral wall of the clamping component, and is centered on the central axis C of the charging cable 9. Additionally, the pivot assembly 20 includes an annular structure 21 and a hanging portion 23, wherein the annular structure 21 is fitted onto the first guide groove 13 and allows the clamping assembly 10 and the charging cable 9 to rotate relative to the pivot assembly 20 about the central axis C. In other words, the clamping assembly 10 and the charging cable 9 have rotational freedom relative to the pivot assembly 20 in the direction of the central axis C.

[0041] In this embodiment, the clamping assembly 10 is fitted and fixed to the outer peripheral surface 90 of the charging cable 9 in, for example, a two-piece assembly. The clamping assembly 10 includes a first fitting 11 and a second fitting 12. The inner annular surface of the second fitting 12 is at least partially fitted onto the outer peripheral wall of the first fitting 11, such that the first fitting 11 and the second fitting 12 are connected to each other by, for example, internal and external threads, while forming a first guide groove 13 on the outer peripheral wall of the first fitting 11.

[0042] In this embodiment, the first assembly 11 has a limiting portion 110 and an inner pressure portion 111 located at opposite ends. The second assembly 12 has a pushing slope 120, which is spatially opposite to the inner pressure portion 111 of the first assembly 11. When the first assembly 11 and the second assembly 12 are connected by internal and external threads, the first guide groove 13 is formed between the limiting portion 110 and the second assembly 12. When the first assembly 11 and the second assembly 12 are connected, the pushing slope 120 presses against the inner pressure portion 111, causing the inner pressure portion 111 to press inward against the outer peripheral surface 90 of the charging cable 9. Thus, the clamping assembly 10 can be securely fitted onto the outer peripheral surface 90 of the charging cable 9. In this embodiment, the first assembly 11 includes a hollow portion 14 that penetrates the limiting portion 110 and the inner pressure portion 111, fitting and adhering to the outer peripheral surface 90 of the charging cable 9. In this embodiment, the inner pressure part 111 is more specifically provided by a plurality of protrusions surrounding the central axis C, and the plurality of protrusions are parallel to the central axis C, with one end of the first assembly 11 intersecting the second assembly 12 and protruding outward. When the first assembly 11 and the second assembly 12 are paired with each other and connected by internal and external threads, the pushing inclined surface 120 approaches and presses against the plurality of protrusions inward, so that the protrusions are firmly pressed against the outer peripheral surface 90 of the charging cable 9, thereby fixing the clamping assembly 10 to the charging cable 9. Of course, the way in which the clamping assembly 10 is fixed to the charging cable 9 by the engagement of the first assembly 11 and the second assembly 12 is not limited to the aforementioned embodiments, and any mechanism that can fit and fix the clamping assembly 10 to the charging cable 9 is applicable to the present invention. It is worth noting that after the clamping assembly 10 is fixed to the charging cable 9, a first guide groove 13 structure is provided on the outer peripheral wall, the first guide groove 13 being centered on the central axis C of the charging cable 9.

[0043] In this embodiment, the pivot assembly 20 provides the clamping assembly 10 and the charging cable 9 with rotational freedom in the C direction of the central axis through the annular structure 21. The annular structure 21 includes two semi-circular bearing portions 211 and 212, which are paired and connected to form the annular structure 21, which fits onto the first guide groove 13. Additionally, in this embodiment, the pivot assembly 20 also includes an outer sleeve 22. The inner annular surface of the outer sleeve 22 has a second guide groove 221, spatially opposite to the first guide groove 13 of the clamping assembly 10 and the annular structure 21 formed by the paired connection of the two semi-circular bearing portions 211 and 212. The inner and outer annular surfaces of the annular structure 21 are respectively accommodated in the first guide groove 13 of the clamping assembly 10 and the second guide groove of the outer sleeve 22. The outer sleeve 22 allows rotation relative to the clamping assembly 10 via the annular structure 21.

[0044] In this embodiment, the outer casing 22 includes, for example, two half-shells, each with a threaded hole 224 at its bottom, which are connected and locked together. Additionally, each of the two half-shells has a locking protrusion 222 at its top, and the hanging portion 23 is clamped between the locking protrusions 222 of the two half-shells. In this embodiment, the locking protrusion 222 includes, for example, a first locking hole 223, and the hanging portion has a second locking hole 231. The pivot assembly 20 also includes a locking member 232, which clamps the hanging portion 23 between the locking protrusions 222 of the two half-shells through the first locking hole 223 and the second locking hole 231. In this embodiment, the locking member 232 clamps the hanging portion 23 between the locking protrusions 222 of the two half-shells, for example, by engaging with a nut 233. Of course, the way the outer casing 22 connects to the hanging portion 23 can be varied according to actual application requirements, and the present invention is not limited thereto.

[0045] It should be noted that, in this embodiment, the hanging part 23 is disposed adjacent to the periphery of the annular structure 21 to achieve the suspension function. In this embodiment, the top surface of the hanging part 23 also has a through-hole 234 for assembling a hanging rope (not shown) to pass through and be fixed, so as to suspend the movable charging cable holder 1 and the charging cable 9 clamped therein. In one embodiment, one end of the hanging rope is connected to the pivot assembly 20 through the through-hole 234, for example, wrapped around the locking member 232, which helps to simplify the installation of the hanging rope. Of course, the present invention is not limited thereto. In addition, the other end of the hanging rope can be fixed at a high place or connected to a pulley and a counterweight, for example. It is worth noting that the arrangement of the hanging rope does not affect the rotational freedom of the clamping assembly 10 and the charging cable 9 in the direction of the central axis C. Since the clamping assembly 10 and the charging cable 9 have rotational freedom in the direction of the central axis C relative to the pivot assembly 20, and the hanging part 23 of the pivot assembly 20 is fixed at a high place by a hanging rope or connected to a pulley and a counterweight, it can provide a mid-section support point for the charging cable 9. When the user holds the charging gun head and pulls the charging cable, the movable charging cable holder 1 allows the clamping assembly 10 and the charging cable 9 to rotate in the direction of the central axis C, which can prevent the charging cable from being unable to straighten and tangling into a circle, and solve the problem of the charging cable 9 curling under force. Of course, the present invention is not limited to this, and will not be elaborated further.

Figure 6 is a perspective structural diagram of the movable charging cable clamp according to the second embodiment of the present invention. Figure 7 is an exploded structural diagram of the movable charging cable clamp according to the second embodiment of the present invention. Figure 8 is a cross-sectional structural diagram of the movable charging cable clamp according to the second embodiment of the present invention. In this embodiment, the movable charging cable clamp 1a is similar to the movable charging cable clamp 1 shown in Figures 1 to 4, and the same component reference numerals represent the same components, structures, and functions, which will not be described again here. Referring to Figures 5 to 8, the present invention further provides a movable charging cable clamp 1a, wherein the pivot component 20a provides the clamping component 10a and the charging cable 9 with rotational freedom in the direction of the central axis C through the annular structure 21a.

[0047] In this embodiment, the annular structure 21a is a sliding bearing, consisting of an inner ring 213 and an outer ring 214. The inner ring 213 of the sliding bearing is fitted onto the first guide groove 13. Additionally, in this embodiment, the pivot assembly 20a further includes an outer ring sleeve 22a, which is fitted onto the outer ring 214 of the sliding bearing. The outer ring sleeve 22a is, for example, integrally formed from an elastic metal ring, and can be directly fitted onto the outer ring 214 of the sliding bearing, allowing rotation relative to the clamping assembly 10a via the sliding bearing.

[0048] In this embodiment, the top of the outer ring sleeve 22a has a locking protrusion 222, which includes a first locking hole 223. Additionally, the hanging part 23 has a second locking hole 231. Furthermore, the pivot assembly 20a also includes a bolt 232, which clamps the hanging part 23 between the locking protrusions 222 through the first locking hole 223 and the second locking hole 231. In this embodiment, the bolt 232 clamps the hanging part 23 between the locking protrusions 222 of the outer ring sleeve 22a, for example, by engaging with a nut 233. Of course, the way the outer ring sleeve 22a connects to the hanging part 23 can be varied according to actual application requirements, and the present invention is not limited thereto.

[0049] On the other hand, in this embodiment, the clamping assembly 10a is also fitted and fixed to the outer peripheral surface 90 of the charging cable 9 in a combination of a first assembly 11 and a second assembly 12. In this embodiment, the limiting portion 110 of the first assembly 11 and the second assembly 12 have, for example, a hexagonal outline to facilitate the operation of the first assembly 11 and the second assembly 12 to engage and connect with each other to fix the charging cable 9. Of course, the outline of the limiting portion 110 can be adjusted according to actual application requirements, and the first guide groove 13 formed between the limiting portion 110 and the second assembly 12 is not affected by it, so it will not be described in detail here.

[0050] Figure 9 is a schematic diagram of the movable charging cable clamp according to the third embodiment of the present invention for clamping the charging cable. Figure 10 is a perspective structural view of the movable charging cable clamp according to the third embodiment of the present invention. Figure 11 is an exploded view of the movable charging cable clamp according to the third embodiment of the present invention. Figure 12 is a cross-sectional structural view of the movable charging cable clamp according to the third embodiment of the present invention. In this embodiment, the movable charging cable clamp 1b is similar to the movable charging cable clamp 1 shown in Figures 1 to 4, and the same component reference numerals represent the same components, structures, and functions, which will not be described again here. Referring to Figures 9 to 12, the present invention further provides a movable charging cable clamp 1b, wherein its pivot component 20b provides the clamping component 10 and the charging cable 9 with rotational freedom in the direction of the central axis C through a thin metal ring 22b.

[0051] In this embodiment, the pivot assembly 20b is directly fitted onto the first guide groove 13 of the clamping assembly 10 via a thin metal ring 22b. The periphery of the thin metal ring 22b also includes a locking protrusion 222, which includes a first locking hole 223. Additionally, the hanging part 23 has a second locking hole 231. The pivot assembly 20b also includes a locking member 232, which locks the locking protrusion 222 and the hanging part 23 through the first locking hole 223 and the second locking hole 231. In this embodiment, the locking member 232, for example, clamps the hanging part 23 between the locking protrusions 222 of the thin metal ring 22b by engaging with a nut 233. Of course, the way the thin metal ring 22b connects to the hanging part 23 can be varied according to actual application requirements, and the present invention is not limited thereto.

[0052] In summary, this invention provides a movable charging cable holder that provides rotational freedom along the central axis through a semi-circular bearing, an annular bearing, or a thin metal ring, thus achieving a mid-section support point for the charging cable. This effectively prevents the charging cable from becoming tangled and unable to straighten, avoiding damage to the charging cable and charging gun. The movable charging cable holder of this invention provides rotational freedom along the central axis for the charging cable held in place by the clamping assembly through the combination of a clamping component and a pivoting component. The clamping component can be fixed to the outer circumference of various charging cables through the meshing connection of two fitting parts. Furthermore, when the hanging part of the pivoting component is fixed at a height by a rope or connected to a pulley and counterweight, it provides a mid-section support point for the charging cable. Because the clamping assembly and the charging cable have rotational freedom relative to the pivot assembly in the central axis direction, the movable charging cable holder allows the clamping assembly and the charging cable to rotate in the central axis direction when the user holds the charging gun head and pulls the charging cable. This prevents the charging cable from being unable to straighten and becoming tangled, solving the problem of the charging cable curling under force. On the other hand, the rotation between the clamping assembly and the pivot assembly is achieved through a ring-shaped structure such as a semi-circular bearing, a ring bearing, or a thin metal ring. The overall structure is simple, easy to assemble, and suitable for various types of charging cables. In addition, the hanging part of the pivot assembly is combined with the locking protrusion of the outer shell or outer ring sleeve for fixing with a bolt, which simplifies the installation of the hanging rope. Thus, the movable charging cable holder of the present invention provides support for the charging cable while solving the problem of the charging cable being unable to straighten and becoming tangled, effectively avoiding situations that may cause damage to the charging cable and the charging gun head.
