Detailed Implementation

[0030] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0031] The charging gun is connected to an electrical wire. During charging, because the charging gun is suspended in the air, the connection between the electrical wire and the charging gun is relatively fragile. Furthermore, the electrical wire itself has a certain weight, which can cause bending at the connection point. Over time, this can lead to cracking of the outer sheath at the connection point, potentially causing safety hazards such as electrical leakage. To address these issues, this application provides a charging device and charging system, which are described in detail below.

[0032] Firstly, referring to Figures 1 to 3 This application discloses a charging device, including a clamping assembly, a charging cable 4, and a charging gun 5 connected to the first end of the charging cable 4. The clamping assembly includes two opposing clamping members 3, two movable members 2, and two force-applying mechanisms 1. The two movable members 2 are respectively connected to the two clamping members 3 and to the two force-applying mechanisms 1. The force-applying mechanisms are connected to the charging gun 5. The force-applying mechanism 1 includes an elastic member 12. The clamping assembly is in a clamping state. When the clamping assembly is in the clamping state, the force-applying mechanism 1 applies a force toward the charging cable 4 to the movable members 2 under the elastic force of the elastic member 12, so that the two clamping members 3 clamp the first end of the charging cable 4.

[0033] This charging device is compatible with various types of new energy vehicles that require charging, such as pure electric vehicles and plug-in hybrid electric vehicles. The charging gun 5 can be a liquid-cooled charging gun, which uses liquid cooling technology for heat dissipation. The charging gun 5 may be equipped with a handle 8 for easy gripping. When using this charging device to charge a new energy vehicle, the user holds the handle 8 and inserts the charging gun 5 into the charging port of the new energy vehicle. During charging, the charging cable 4 transfers electrical energy to the charging gun 5, and the charging gun 5 transfers electrical energy to the new energy vehicle.

[0034] The charging cable 4 has a first end and a second end. The first end of the charging cable 4 is electrically connected to the charging gun 5, and the second end of the charging cable 4 can be electrically connected to a charging pile or a plug. During use, the clamping assembly is in a clamping state, with two clamping members 3 clamping the first end of the charging cable 4. The force applied towards the charging cable 4 by the force-applying mechanism 1 to the moving member 2 is transmitted to the clamping members 3, causing the two clamping members 3 to tightly clamp the first end of the charging cable 4.

[0035] Two force-applying mechanisms 1 are symmetrically arranged, and two movable moving parts 2 are also symmetrically arranged. The clamping member 3 is an arc-shaped plate, and the arcs of the two clamping members 3 are symmetrical. The moving part 2 can move relative to the charging gun 5. The movement of the moving part 2 can be sliding, rotating, or a combination of these movements. The moving part 2 can include at least one rod. The preferred movement of the moving part 2 is sliding, in which case the moving part 2 is fixedly connected to the clamping member 3, and the connection method can be threaded connection, bonding, welding, etc. The force-applying mechanism 1 also includes other components besides the elastic member 12; however, the force-applying mechanism 1 may also include only the elastic member 12.

[0036] In this embodiment, when the clamping assembly is in the clamping state, the two clamping members 3 clamp and fix the first end of the charging cable 4, which can prevent the first end of the charging cable 4 from bending during use of the charging device, thereby preventing the outer sheath of the first end of the charging cable 4 from cracking and avoiding safety hazards such as leakage. In addition, when the clamping assembly is in the clamping state, the force applying mechanism 1, under the elastic force of the elastic member 12, applies a force toward the charging cable 4 to the movable member 2, thereby enabling the two clamping members 3 to maintain clamping on the first end of the charging cable 4, preventing loosening of the clamp, and adapting to charging cables 4 with different outer diameters.

[0037] The clamping assembly also has an unclamped state, in which the charging cable 4 is located outside the two clamping members 3, that is, the charging cable 4 is not located between the two clamping members 3. When the charging device is not in use, the clamping assembly can be in the unclamped state. When using this charging device, the clamping assembly must first be switched from the unclamped state to the clamped state. During this process, an external force can be manually applied to the two movable parts 2 away from the charging cable 4, so that the two movable parts 2 overcome the elastic force of the elastic member 12 and move away from the charging cable 4. When the two movable parts 2 move away from the charging cable 4, they drive the two clamping parts 3 to move away from the charging cable 4, that is, they drive the two clamping parts 3 to move in opposite directions. When the distance between the two clamping parts 3 is sufficient for the charging cable 4 to enter, the charging cable 4 is manually pulled between the two clamping parts 3. After that, the external force applied to the movable parts 2 is released. After the external force applied to the movable parts 2 is released, the force applying mechanism 1, under the action of the elastic force of the elastic member 12, drives the two movable parts 2 to move toward the charging cable 4. When the two movable parts 2 move toward the charging cable 4, they drive the two clamping parts 3 to move toward the charging cable 4, that is, they drive the two clamping parts 3 to move toward each other, so that the two clamping parts 3 clamp the first end of the charging cable 4.

[0038] After the charging device is used, if you want the charging cable 4 to come out between the two clamping parts 3, you can manually apply an external force away from the charging cable 4 to the two movable parts 2, so that the two movable parts 2 overcome the elastic force of the elastic part 12 and move away from the charging cable 4. When the two movable parts 2 move away from the charging cable 4, they will drive the two clamping parts 3 to move away from the charging cable 4, that is, drive the two clamping parts 3 to move in opposite directions. When the distance between the two clamping parts 3 is sufficient for the charging cable 4 to come out, you can manually pull out the charging cable 4.

[0039] In some embodiments, refer to Figure 2 and Figure 4 The movable part 2 is slidably connected to the charging gun 5 along a first direction, which is consistent with the relative direction of the two clamping parts 3. The force application mechanism 1 also includes a rotating part 13, which is rotatably connected to the charging gun 5 and is movably connected to the movable part 2 through a connecting shaft 14. When the clamping assembly is in the clamping state, the elastic part 12 is configured to apply elastic force to the rotating part 13 so that the rotating part 13 applies a force toward the charging cable 4 to the movable part 2 through the connecting shaft 14.

[0040] The first direction can be referenced. Figure 2 and Figure 4 The direction indicated by arrow B. The movable member 2 is slidably connected to the charging gun 5 via a guide structure extending along the first direction, such as guide segment 62 in guide member 6. At least a portion of the movable member 2 directly connected to the clamping member 3, such as the second rod 22, extends along the first direction. The elastic member 12 can be a torsion spring, a spiral spring, etc. When the clamping assembly is in the clamped state, the elastic member 12 is configured to apply a spring force to the rotating member 13, under which the rotating member 13 has a rotational tendency to rotate toward the charging cable 4. The rotating member 13 applies a force toward the charging cable 4 to the movable member 2 via the connecting shaft 14. The force toward the charging cable 4 applied by the connecting shaft 14 to the movable member 2 is parallel to the first direction.

[0041] When using this charging device, the clamping assembly must first be switched from the unclamped state to the clamped state. During this process, an external force can be manually applied to the two movable parts 2 away from the charging cable 4, causing the two movable parts 2 to slide away from the charging cable 4 against the elastic force of the elastic member 12. When the two movable parts 2 slide away from the charging cable 4, they drive the two rotating parts 13 to rotate away from the charging cable 4 against the elastic force of the elastic member 12, and drive the two clamping parts 3 to move away from the charging cable 4, that is, drive the two clamping parts 3 to move in opposite directions. When the distance between the two clamping members 3 is sufficient for the charging cable 4 to enter, manually pull the charging cable 4 between the two clamping members 3. Then, release the external force applied to the movable member 2. After the external force applied to the movable member 2 is released, under the elastic force of the elastic member 12, the two rotating members 13 rotate toward the charging cable 4, and drive the two movable members 2 to slide toward the charging cable 4. The sliding of the two movable members 2 toward the charging cable 4 drives the two clamping members 3 to move toward the charging cable 4, that is, drive the two clamping members 3 to move towards each other, so that the two clamping members 3 clamp the first end of the charging cable 4. In this embodiment, during the process of switching the clamping assembly from the unclamped state to the clamped state, the movement of the movable member 2 is sliding, and the movement of the clamping member 3 is moving, to ensure that for charging cables 4 with different outer diameters, the clamping member 3 can have sufficient contact area with the charging cable 4 to stably clamp charging cables 4 with different outer diameters.

[0042] In some embodiments, refer to Figure 2 and Figure 4 The movable component 2 includes a first rod 21, and a first groove 211 is opened on the top surface of the first rod 21. The first groove 211 extends along a second direction, which is perpendicular to the first direction. The connecting shaft 14 is slidably connected in the first groove 211, and the connecting shaft 14 is rotatably connected to the rotating component 13.

[0043] The rotating component 13 has a first shaft hole that mates with the connecting shaft 14. The first shaft hole and the connecting shaft 14 mate to achieve a rotatable connection between the connecting shaft 14 and the rotating component 13. A first anti-detachment block 15 is connected to the top of the connecting shaft 14. The first anti-detachment block 15 is located above the first shaft hole of the rotating component 13 to prevent the rotating component 13 from detaching from the connecting shaft 14.

[0044] The first rod 21 extends along the second direction. The second direction can be referenced... Figure 2 and Figure 4 The direction indicated by arrow C. When the rotating component 13 rotates, the motion component along the second direction will drive the connecting shaft 14 to slide along the first slide groove 211, and the motion component along the first direction will drive the movable component 2 to slide along the first direction. During the process of switching the clamping assembly from an unclamped state to a clamped state, the rotation of the rotating component 13 can be converted into the linear sliding of the movable component 2 by the setting of the connecting shaft 14 and the first slide groove 211.

[0045] The movable component 2 also includes a second rod 22, the two ends of which are fixedly connected to the first rod 21 and the clamping component 3, respectively. As one example, there is one second rod 22, which extends along a first direction. As another example, there are two second rods 22, which are arranged in a crisscross pattern.

[0046] In some embodiments, refer to Figure 4 A second groove 212 is provided on at least one side of the first rod 21. The second groove 212 extends along the second direction and communicates with the first groove 211. A slider 16 is fixedly connected to the connecting shaft 14. The slider 16 is slidably connected in the second groove 212.

[0047] The second slide groove 212 is located on at least one side of the first slide groove 211 along its width direction. Preferably, there is one second slide groove 212, located on the side of the first slide groove 211 opposite to the clamping member 3 along its width direction. The connection between the slider 16 and the connecting shaft 14 can be achieved through threaded connection, bonding, welding, etc. In this embodiment, the slider 16 and the second slide groove 212 prevent the connecting shaft 14 from dislodging from the first slide groove 211 and prevent the connecting shaft 14 from wobbling up and down, thus ensuring the stability of the connecting shaft 14 during sliding.

[0048] In some embodiments, refer to Figure 2 The elastic element 12 is a torsion spring; the force application mechanism also includes a fixing element 11 connected to the charging gun 5. The fixing element 11 is rotatably connected to a rotating shaft. The rotating shaft is fixedly connected to the end of the rotating element 13 away from the movable element 2. The torsion spring is sleeved on the rotating shaft, and the two ends of the torsion spring are respectively connected to the fixing element 11 and the rotating element 13.

[0049] The fixing member 11 protrudes from the outer surface of the charging gun 5 and can be a plate-like structure. The fixing member 11 can be connected to the charging gun 5 by screws, adhesive, welding, etc. A second shaft hole is provided on the fixing member 11 to mate with the rotating shaft, enabling rotational connection between the rotating shaft and the fixing member 11. The rotating shaft rotates with the rotating member 13, and the connection between the rotating shaft and the rotating member 13 can be adhesive, welding, etc. The torsion spring can be connected to the fixing member 11 and the rotating member 13 by hook connection, snap-fit, welding, etc. In this embodiment, the fixing member 11 provides a mounting point for the end of the rotating member 13 furthest from the movable member 2, and maintains a certain distance between the rotating member 13 and the charging gun 5, preventing interference between the rotating member 13 and the charging gun 5 during rotation.

[0050] In some embodiments, refer to Figure 2 and Figure 4The charging gun 5 is fixedly connected to a guide member 6, which includes a guide section 62 extending along a first direction. The movable member 2 includes a mating part 23, on which a guide groove 231 is provided. The mating part 23 is slidably connected to the guide section 62 through the guide groove 231.

[0051] The guide member 6 can be connected to the charging gun 5 via threaded connection, screw connection, bonding, welding, etc. The guide member 6 also includes a connecting section 61 connected to the guide segment 62, with one end of the connecting section 61 away from the guide segment 62 fixedly connected to the charging gun 5. The mating component 23 is fixedly connected to the second rod 22. As one example, the guide groove 231 is circumferentially closed, is a square groove, and is fitted onto the guide segment 62. As another example, the guide groove 231 is not circumferentially closed, is located at the bottom of the mating component 23, and has an open bottom. In this embodiment, the mating component 23 is slidably connected to the guide segment 62 via the guide groove 231 to limit the sliding direction of the movable component 2 and prevent the movable component 2 from deviating from the set direction during sliding.

[0052] In some embodiments, a second anti-detachment block 63 is fixedly connected to one end of the guide segment 62 away from the connecting segment 61 to prevent the mating part 23 from sliding out of the guide segment 62.

[0053] In some embodiments, refer to Figure 1 , Figure 3 and Figure 5 The charging device also includes a cable tie 9, which is used to bind the wound charging cable 4. The cable tie 9 includes a body 91, and the body 91 has a first connecting structure and a second connecting structure on two opposite sides along the thickness direction. The first connecting structure and the second connecting structure are detachably connected.

[0054] The charging cable 4 is quite long, so a portion of the charging cable 4 can be coiled up and then secured with the cable tie 9 to keep the charging cable 4 organized and prevent it from dragging on the ground, thus avoiding dirt and wear caused by the charging cable 4 dragging on the ground.

[0055] When the charging cable 4 is secured by the cable tie 9, the cable tie 9 is wound around the coiled portion of the charging cable 4, and the first connecting structure is connected to the second connecting structure to prevent the cable tie 9 from loosening. As an example, the first connecting structure is a hook and loop fastener 92, and the second connecting structure is a hook and loop fastener 93. In other examples, the first connecting structure can be a female snap, a first magnetic component, etc., and the second connecting structure can be a female snap, a second magnetic component with the opposite magnetic properties to the first magnetic component, etc.

[0056] In some embodiments, refer to Figure 3 and Figure 5The end of the belt body 91 is connected to a connecting sleeve 94, which is movably sleeved on the charging cable 4 and located between the first end and the second end of the charging cable 4.

[0057] The connection between the connecting sleeve 94 and the cable tie 91 is a fixed connection, such as adhesive bonding or heat fusion bonding. The connecting sleeve 94 can move along the length of the charging cable 4. The connecting sleeve 94 can be made of an elastic material, such as silicone or ordinary rubber. When the connecting sleeve 94 is made of an elastic material, it can remain in that position when moved to a certain position on the charging cable 4. In this embodiment, by connecting the cable tie 9 to the unwound charging cable 4 through the connecting sleeve 94, the cable tie 9 can be prevented from being lost. In addition, by moving the connecting sleeve 94, the cable tie 9 can be adjusted to a suitable position before winding the charging cable 4.

[0058] In some embodiments, refer to Figure 2 Each clamp 3 has an anti-slip pad 7 on its inner surface facing the charging cable 4.

[0059] The anti-slip pad 7 is an arc-shaped pad. A single clamping member 3 can have a single, fully-enclosed anti-slip pad 7 covering its entire inner surface. Alternatively, a single clamping member 3 can have multiple anti-slip pads 7, spaced apart. The anti-slip pad 7 is made of a flexible material, such as rubber or polyurethane. The inner surface of the anti-slip pad 7 facing the charging cable 4 may have raised anti-slip textures.

[0060] In this embodiment, by setting the anti-slip pad 7, on the one hand, the charging cable 4 can be prevented from slipping between the two clamping members 3, ensuring the clamping stability of the charging cable 4. On the other hand, it can protect the charging cable 4 and avoid the risk of the charging cable 4 being indented or damaged due to the clamping members 3 directly contacting the charging cable 4.

[0061] Secondly, embodiments of this application provide a charging system, including a charging pile and the charging device provided in the first aspect. This charging system is suitable for new energy vehicles requiring charging, such as pure electric vehicles and plug-in hybrid electric vehicles. The charging pile is electrically connected to the charging cable 4 in the charging device.

[0062] Since the charging system includes the aforementioned charging device, it also possesses the beneficial effects of the aforementioned charging device, which will not be elaborated upon here.

[0063] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0064] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of protection of this application, and these forms are all within the protection scope of this application.
