Description

Technical Field

[0001] This application relates to the field of charging pile technology, and in particular to a charging gun cable suspension device and a charging pile. Background Technology

[0002] Charging stations utilize a charging cable suspension device to extend and retract the charging cable, increasing the cable's distance from the ground and reducing drag. Currently, this suspension device is designed to open and close, ensuring connection to vehicles at greater distances. However, current devices cannot fully open or close during this process, affecting the cable's ability to connect to vehicles.

[0003] Therefore, improving the ability of charging gun cables to connect to vehicles has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] This application proposes a charging gun cable suspension device and a charging pile to improve the ability of the charging gun cable to connect to a vehicle.

[0005] To achieve the above objectives, this application discloses the following technical solutions:

[0006] In a first aspect, this application provides a charging gun cable suspension device for use in charging piles. The charging gun cable suspension device includes a fixed base, a swing arm assembly, and a transmission assembly.

[0007] The fixed base is used for fixed connection with the charging pile;

[0008] The first end of the swing arm assembly is rotatably connected to the first side of the fixed base, and the second end of the swing arm assembly is used to clamp the charging gun cable of the charging pile. When the swing arm assembly is closed, the second side of the swing arm assembly is in contact with the first side of the fixed base.

[0009] The first end of the transmission component is connected to the third side of the swing arm component, and the second end of the transmission component is connected to the first side of the fixed base.

[0010] In some embodiments, when the swing arm assembly is in the open state, the angle between the second side of the swing arm assembly and the first side of the fixed base is in the range of (0°, 180°).

[0011] In some embodiments, the charging gun cable suspension device further includes a pivot assembly mounted on a first side of the fixed base, and the first end of the swing arm assembly is rotatably connected to the first side of the fixed base via the pivot assembly.

[0012] In some embodiments, the charging gun cable suspension device further includes a drive assembly mounted on either the third side of the swing arm assembly or the first side of the fixed base.

[0013] In some embodiments, one of the third side of the swing arm assembly and the first side of the fixed base includes a mounting groove, in which the drive assembly is disposed.

[0014] In some embodiments, the transmission assembly includes a guide rail, a slide bar, and a slider;

[0015] The guide rail is mounted on either the third side of the swing arm assembly or the first side of the fixed base;

[0016] The slider is slidably mounted within the guide rail;

[0017] One end of the slide bar is connected to the output shaft of the drive assembly, and the other end of the slide bar is connected to the slider.

[0018] In some embodiments, when the guide rail is disposed on the first side of the fixed base and the drive assembly is disposed on the third side of the swing arm assembly, there is a gap between the lower edge of the guide rail and the upper edge of the swing arm assembly in the height direction, and the main body of the slide ruler is disposed within the gap; wherein, on the side where the lower edge of the guide rail is located, the first end of the slide ruler is connected to the slider; on the side where the upper edge of the swing arm assembly is located, the second end of the slide ruler is connected to the output shaft of the drive assembly.

[0019] In some embodiments, the transmission assembly includes a base, a first slide bar, and a second slide bar;

[0020] One end of the first slide is connected to the output shaft of the drive assembly, and the other end of the first slide is rotatably connected to one end of the second slide.

[0021] The other end of the second slide rule is connected to the base.

[0022] In some embodiments, when the base is mounted on the first side of the fixed base and the drive assembly is disposed within the swing arm assembly, there is a gap between the lower edge of the base and the upper edge of the swing arm assembly in the height direction, and the main bodies of the first slide and the second slide are disposed within the gap; wherein, on the side where the lower edge of the base is located, the first end of the second slide is connected to the base; the second end of the second slide is rotatably connected to the first end of the first slide; on the side where the upper edge of the swing arm assembly is located, the second end of the first slide is connected to the output shaft of the drive assembly.

[0024] As can be seen from the above technical solution, since one end of the transmission component is connected to the third side of the swing arm component, the opening angle of the swing arm component is increased when the swing arm component is opened, so that the charging gun cable is dragged a longer distance, thereby enabling it to connect to vehicles at a greater distance and increasing the connection range of the charging pile.

[0044] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. The described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.

[0045] To achieve the above objectives, this application discloses the following technical solutions:

[0046] See Figure 1 and Figure 2 , Figure 1 A perspective view of the charging gun cable suspension device 10 in a closed state is disclosed; Figure 2 A perspective view of the charging gun cable suspension device 10 in the open state has been released.

[0047] The charging gun cable suspension device shown in the figure includes a fixed base 11, a swing arm assembly 12, and a transmission assembly 13. The fixed base 11 is used for fixed connection with the charging pile. The swing arm assembly 12 is used to install the charging gun cable. The first end of the swing arm assembly 12 is rotatably connected to the first side 11a of the fixed base 11, and the second end of the swing arm assembly 12 is used to clamp the charging gun cable of the charging pile. In the closed state, the second side 12a of the swing arm assembly 12 is in contact with the first side 11a of the fixed base 11. The first end of the transmission assembly 13 is connected to the third side 11c of the swing arm assembly 12, and the second end of the transmission assembly 13 is connected to the first side 11a of the fixed base 11.

[0048] Since one end of the transmission assembly 13 is connected to the third side 12b of the swing arm assembly 12, and the third side 12b intersects with the second side 12a, the opening angle of the swing arm assembly 12 is increased when the swing arm assembly 12 is opened, so that the charging gun cable is dragged a longer distance, thereby enabling the connection of vehicles at a greater distance and increasing the connection range of the charging pile.

[0049] In the illustration, the fixed base 11 can be a cuboid structure with four sides. The aforementioned first side 11a can be understood as at least one of the four sides. For example, in the illustration, two swing arm assemblies 12 are symmetrically arranged on two opposite sides. Of course, in some examples of this application, the fixed base 11 can have three sides, five sides, six sides, etc., with at least one swing arm assembly 12 on each side. When swing arm assemblies 12 are arranged on multiple sides, they are arranged in a clockwise or counterclockwise direction to reduce interference between swing arm assemblies 12 on adjacent sides during state switching. Figures 3 to 5 As shown.

[0050] In some instances, the aforementioned fixed base 11 may be a solid structure; in other instances, the fixed base 11 may be a frame structure, and adopting a frame structure can reduce the weight of the charging gun cable suspension device 10.

[0051] The swing arm assembly 12 has opposing sides, and upper and lower edges connecting the two opposing sides. To reduce the space occupied by the swing arm assembly 12 when folded, the two sides are planar structures. The aforementioned second side 12a can be understood as one of the opposing sides of the swing arm assembly 12. The third side 12b can be understood as the upper or lower edge of the swing arm assembly 12. At least one of the two opposing sides, the upper edge, and the lower edge can be a planar or curved surface. For example, if the swing arm assembly is a cuboid structure, the two sides, the upper edge, and the lower edge are planar structures; if the swing arm assembly is a cylindrical structure, the two sides, the upper edge, and the lower edge are arc-shaped structures.

[0052] In the above structure, when the swing arm assembly 12 is in the open state, the angle between the second side 12a of the swing arm assembly 12 and the first side 11a of the fixed base 11 is in the range of (0°, 180°). As a result, the swing arm assembly 12 can be extended to its longest state, thereby improving the ability of the charging gun cable to connect to the vehicle.

[0053] The swing arm assembly 12 includes at least two swing arms. In one embodiment, taking the swing arm assembly 12 as an example, the two swing arms are a first swing arm 121 and a second swing arm 122, wherein the first swing arm 121 is connected to the first side surface 11a, and the second swing arm 122 is movably connected to the first swing arm 121. Figure 3 and Figure 7 As shown.

[0054] The aforementioned swing arm assembly 12 is used to fix the charging gun cable. The charging gun cable can be connected to the swing arm assembly 12 via a flexible component, such as a rope. Additionally, the swing arm assembly 12 of this application is also provided with a cable clamp 16 for fixing the charging gun cable. This cable clamp 16 can fix the charging gun cable. The cable clamp 16 can rotate around its own axis to accommodate multi-angle adjustments of the charging gun cable.

[0055] In some examples, the charging gun cable suspension device 10 further includes a pivot assembly 14 mounted on the first side of the fixed base 11, and the first end of the swing arm assembly 12 is rotatably connected to the first side 11a of the fixed base 11 via the pivot assembly 14. Alternatively, in some examples, the first end of the swing arm assembly 12 is rotatably connected to the first side 11a of the fixed base 11 via a hinge. Any method that enables the first end of the swing arm assembly 12 to be rotatably connected to the first side 11a of the fixed base 11 is within the scope of protection of this application, such as... Figure 4 and Figure 5 Understandably, the swing arm assembly 12, which is connected to the fixed base 11 via the pivot assembly 14, requires less effort to rotate.

[0056] In some examples of this application, the charging gun cable suspension device 10 may further include a drive assembly 15, which is mounted on either the third side 12b of the swing arm assembly 12 or the first side 111 of the fixed base 11. This drive assembly 15 provides a restoring force during the switching of the swing arm assembly 12 from an open state to a closed state. The drive assembly 15 may be hydraulically controlled, electrically controlled, a door closer, etc., as long as it enables the swing arm assembly 12 to switch from an open state to a closed state, it is within the scope of protection of this application.

[0057] To reduce the external space occupied by the drive assembly 15, one of the third side 12b of the swing arm assembly 12 and the first side 111 of the fixed base 11 includes a mounting groove 1211, within which the drive assembly 15 is disposed. Arranging the drive assembly 15 within the mounting groove 1211 reduces the time the drive assembly 15 is exposed to the outside, thus extending its service life.

[0058] In some embodiments, the transmission assembly 13 may include a guide rail 131, a slider 132, and a block 133. The guide rail 131 is mounted on the other of the third side 12b of the swing arm assembly 12 and the first side 111 of the fixed base 11. The block 133 is slidably disposed within the guide rail 131. One end of the slider 132 is connected to the output shaft 151 of the drive assembly 15, and the other end of the slider 132 is connected to the block 133. The block 133 can slide along the length of the guide rail 131. When the block 133 gradually slides towards the rotating shaft assembly 14, the angle between the slider 132 and the guide rail 131 and the swing arm assembly 12 gradually increases, and the swing arm assembly 12 gradually opens. When the block 133 gradually slides away from the rotating shaft assembly 14, the angle between the slider 132 and the guide rail 131 and the swing arm assembly 12 gradually decreases, and the swing arm assembly 12 gradually closes.

[0059] When the charging cable is pulled by an external force, the swing arm assembly 12 switches from the closed state to the open state. During this process, the slider 133 moves along the length of the guide rail 131, and the two ends of the slider 132 rotate relative to the slider 133 and the drive assembly 15. After the external force is removed, the drive assembly 15 applies a restoring force, causing the slider 133 to move along the length of the guide rail 131, thereby causing the two ends of the slider 132 to rotate again relative to the slider 133 and the drive assembly 15, thus restoring the swing arm assembly 12 from the open state to the closed state.

[0060] With the guide rail 131 mounted on the first side 111 of the fixed base 11 and the drive assembly 15 mounted on the third side 12b of the swing arm assembly 12, the swing arm assembly 12 and the guide rail 131 have a gap 130a. The slide bar 132 is positioned within the gap 130a. By setting the gap 130a, the slide bar 132 can perfectly avoid collisions during rotation. As described above, the third side 12b can be the upper edge or the lower edge of the swing arm assembly 12. Therefore, the gap 130a can be located between the upper edge of the swing arm assembly 12 and the lower edge of the guide rail 131, or between the lower edge of the swing arm assembly 12 and the upper edge of the guide rail 131. Figure 6 and Figure 8 As shown.

[0061] Specifically, in the height direction, there is a gap 130a between the lower edge of the guide rail 131 and the upper edge of the swing arm assembly 12, and the main body of the slide ruler 132 is disposed within the gap 130a; wherein, on the side where the lower edge of the guide rail 131 is located, the first end of the slide ruler 132 is connected to the slider 133; on the side where the upper edge of the swing arm assembly 12 is located, the second end of the slide ruler 132 is connected to the output shaft 151 of the drive assembly 15.

[0062] See Figure 7 and Figure 8 The swing arm assembly 12 has a cuboid structure. The first end of the slide ruler 132 is connected to the lower edge of the guide rail 131 via the slider 133. The second end of the slide ruler 132 is connected to the upper edge of the swing arm assembly 12 via the output shaft 151. In the open state, the maximum angle between the guide rail 131 and the slide ruler 132 can be 180°, that is, the angle between the second side 12a of the swing arm assembly 12 and the first side 11a of the fixed base 11 can be 180°. Therefore, the swing arm assembly 12 can be fully opened.

[0063] In another embodiment of this application, another transmission assembly 13 is disclosed. Specifically, the transmission assembly 13 includes a base 134, a first slide bar 135, and a second slide bar 136. One end of the first slide bar 135 is connected to the output shaft 151 of the drive assembly 15, and the other end of the first slide bar 135 is rotatably connected to one end of the second slide bar 136. The other end of the second slide bar 136 is connected to the base 134, such as... Figure 9 As shown. Under the action of the drive assembly 15, as the angle between the first slide bar 135 and the second slide bar 136 gradually increases, the swing arm assembly 12 gradually opens; as the angle between the first slide bar 135 and the second slide bar 136 gradually decreases, the swing arm assembly 12 gradually closes.

[0064] With the base 134 mounted on the first side 111 of the fixed base 11 and the drive assembly 15 disposed within the swing arm assembly 12, there is a gap 130a between the swing arm assembly 12 and the base 134. The first slide bar 135 and the second slide bar 136 are both disposed within the gap 130a. As described above, the third side can be the upper edge or the lower edge of the swing arm assembly 12. Therefore, the gap 130a can be located between the upper edge of the swing arm assembly and the lower edge of the guide rail 131, or between the lower edge of the swing arm assembly 12 and the upper edge of the guide rail 131.

[0065] Specifically, in the height direction, there is a gap 130a between the lower edge of the base 134 and the upper edge of the swing arm assembly 12, and the main body parts of the first slide 135 and the second slide 136 are disposed within the gap 130a; wherein, on the side where the lower edge of the base 134 is located, the first end of the second slide 136 is connected to the base 134; the second end of the second slide 136 is rotatably connected to the first end of the first slide 135; on the side where the upper edge of the swing arm assembly 12 is located, the second end of the first slide 135 is connected to the output shaft 151 of the drive assembly 15.

[0066] When the swing arm assembly 12 is in the open state, the angle between the first slide bar 135 and the second slide bar 136 is 180°, and the angle between the second side 12a of the swing arm assembly 12 and the first side 11a of the fixed base 11 is 180°. Therefore, the swing arm assembly 12 can be fully opened.

[0067] like Figure 10 and Figure 11 As shown, Figure 10 A perspective view of a charging pile in a first state provided in an embodiment of this application; Figure 11 This is a perspective view of a charging pile in a second state, provided as an embodiment of this application.

[0068] This application discloses a charging pile, including a main unit 20, a charging gun cable 30, and a charging gun cable suspension device 10 as described above, wherein the swing arm assembly 12 of the charging gun cable suspension device 10 is connected to the charging gun cable 30. Since the charging gun cable suspension device 10 has the aforementioned beneficial effects, the charging pile including the charging gun cable suspension device 10 has corresponding effects.

[0069] In the first state described above, the charging pile 100 is not charging the vehicle 200; in the second state described above, the charging pile 100 is charging the vehicle 200.

[0070] When the charging pile 100 is in the first state described above, the swing arm assembly 12 is in the closed state; when the charging pile 100 is in the second state described above, the swing arm assembly 12 is in the open state.

[0071] During the process of a user pulling the charging gun cable 30 to the charging port of the vehicle 200 for charging, the transmission component 13 switches from the closed state to the open state, and the swing arm component 12 switches from the closed state to the open state. When the charging personnel pull the charging gun cable 30 to hang it on the main unit 20, the transmission component 13 switches from the open state to the closed state, and the swing arm component 12 switches from the open state to the closed state. The swing arm component 12 can bear part of the weight of the charging gun cable 30, effectively reducing the weight of the cable itself and improving the user experience when using the charging gun.

[0072] The charging gun cable suspension device 10 adopts a modular design, which can be designed into different sizes of top mounting structures according to the appearance and structural dimensions of the charging pile host 20. This results in stronger compatibility, higher assembly and maintenance efficiency, and effectively reduces the secondary development and installation costs of the product.

[0073] In addition, the charging gun cable suspension device 10 can prevent the charging gun cable 30 from dragging on the ground and occupying the charging space, making it easier for the charging vehicle owner to park, preventing the charging gun cable 30 and the gun head from being crushed, improving the service life of the charging gun cable 30, and at the same time avoiding electrical safety hazards caused by the wear and tear of the charging gun cable 30 dragging on the ground, thus improving charging safety.

[0074] The charging gun cable suspension device 10 is fixedly connected to the top of the main unit 20. The area of ​​the top device is larger than that of the charging pile, which can prevent other objects from falling from the top and causing accidental damage to the charging pile, such as rain, snow, hail, or foreign objects.

[0075] In the above context, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0076] In the description of the embodiments of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. "And / or" in this article is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone.

[0077] It should be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.
