Description

[0002] With the development of the new energy field, the penetration rate of new energy vehicles is getting higher and higher. Charging piles, as energy replenishment equipment for new energy vehicles, are particularly important in terms of energy replenishment efficiency.

[0003] Circuit heating is a key factor affecting energy replenishment efficiency. In order to reliably dissipate heat from the circuit, many charging piles currently use immersion liquid cooling. Specifically, in the charging gun with a wire core liquid tube, coolant flows between the inner wall of the pipeline skin and the wire core. The coolant is used to efficiently dissipate heat from the wire core to solve the circuit heating problem.

When the bending radius of the wire core and the pipeline sheath are different, the wire core may contact the pipeline sheath, causing the pipeline sheath to be thermally deformed due to heat, which may easily cause the pipeline sheath to rupture, posing a risk of coolant leakage.

[0048] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0049] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists, A and B exist at the same time, and B exists.

They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the embodiments of the present application.

[0052] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0053] For high-power charging piles, during the charging process, the resistance of the wire core will increase as the temperature rises, which will lead to a decrease in charging efficiency. In order to control the temperature of the wire core within an appropriate range, immersion liquid cooling can be used to cool the wire core. The internal structure of the charging gun with the wire core liquid pipe in the immersion liquid cooling method and its installation method with the cabinet are as follows: Figure 1 As shown in , the heat dissipation efficiency of the wire core can be improved by dissipating the heat of the wire core through the coolant in the pipeline sheath, thereby ensuring the high efficiency of charging.

[0054] like Figure 1 As shown in , after one end of the charging gun with the wire core liquid tube is inserted into the cabinet 0200 and connected to the corresponding circuit structure, the end of the pipeline located outside the cabinet 0200 will bend due to gravity. Since the pipeline sheath 0110 is generally made of soft rubber and the wire core 0120 is generally made of metal, the two have different bending strengths and rigidities, and the corresponding bending radius is usually smaller than that of the wire core 0120. Based on this, in Figure 1 At the contact position 0130 shown in the figure, the wire core 0120 and the pipeline sheath 0110 are in contact with each other. Since the temperature of the wire core 0120 is relatively high, the heat of the wire core 0120 is transferred to the pipeline sheath 0110, causing thermal deformation of the pipeline sheath 0110. In severe cases, the pipeline sheath 0110 may rupture and the coolant 0111 may leak.

[0055] In order to solve the above problems, the present application designs a new installation structure of a charging gun with a wire core liquid pipe and a cabinet. Specifically, the wire core does not need to be bent and can be installed in a vertically extended state, so that it will not contact the pipeline skin, thereby avoiding the problem of coolant leakage due to rupture of the pipeline skin. At the same time, the wire core and the pipeline for transporting coolant are separated from each other at the end of the pipeline skin, so that the coolant can flow between the cabinet and the pipeline skin through the separately separated pipeline, thereby achieving reliable heat dissipation of the wire core and ensuring charging efficiency.

[0056] According to one aspect of the embodiment of the present application, a charging gun line installation assembly is provided. Figures 2 to 4 , Figure 2 FIG. 2 shows a partial exploded structure of a charging pile with a charging gun line installation assembly provided in an embodiment of the present application. Figure 3 The structure of the charging gun pipeline installation assembly is shown in the figure. As shown in the figure, the charging gun pipeline installation assembly 100 is applied to the cabinet 200 of the charging pile, and the charging gun pipeline installation assembly 100 includes: a pipeline sheath 110, a wire core 120, a joint 130 and a coolant pipeline 140. The wire core 120 is arranged inside the pipeline sheath 110, and the inner wall of the pipeline sheath 110 and the outer wall of the wire core 120 are used for the coolant 111 to flow. A pipeline connecting part 131 is provided at one end of the joint 130 along the vertical direction (the direction shown by the z-axis in the figure), and a pipe 1311 is provided inside the pipeline connecting part 131 (as shown in the figure). Figure 5 and Figure 6 The pipeline connection portion 131 is connected to one end of the pipeline skin 110, and the pipeline 1311 is connected to the inside of the pipeline skin 110. One end of the wire core 120 is used to connect the charging gun 300, and the other end extends into the pipeline 1311 and is fixed to the connector 130 and forms an electrical contact. The connector 130 is configured to be installed along one side of the radial direction of the pipeline skin 110 (the direction shown by the x-axis in the figure) toward the cabinet 200 and is connected to the conductive component 210 (as shown in the figure) in the cabinet 200. Figure 7 ) so that the end of the pipeline skin 110 connected to the pipeline connecting portion 131 extends approximately in the vertical direction. The coolant pipeline 140 is arranged on the pipeline connecting portion 131, one end of the coolant pipeline 140 is connected to the pipe 1311, and the other end is used to connect to the heat dissipation component 220 (as shown in FIG. Figure 8 The coolant pipeline 140 is connected to the pipeline skin 110 and is used to flow the coolant 111 between the inside of the pipeline skin 110 and the heat dissipation component 220 to dissipate heat for the wire core 120 inside the pipeline skin 110.

[0057] like Figure 2As shown in the figure, the wire core 120 accommodated inside the pipeline sheath 110 is used for transmitting current. Specifically, one end of the wire core 120 is connected to the conductive component 210 in the cabinet 200, and the other end is connected to the charging gun 300 of the charging pile 500, so as to transmit the power of the power source to the new energy vehicle through the charging gun 300, thereby charging the new energy vehicle.

[0058] There is a gap between the inner wall of the pipeline sheath 110 and the wire core 120, and the gap is used to accommodate the coolant 111. The heat generated during the conduction of the wire core 120 is discharged through the flow of the coolant 111. Specifically, a heat dissipation component 220, such as an air cooling component or a liquid cooling component, is provided in the cabinet 200. The coolant 111 that absorbs the heat of the wire core 120 enters the heat dissipation component 220 through the coolant pipeline 140, and the heat dissipation component 220 dissipates and cools the coolant 111, so that the temperature of the coolant 111 is reduced. The cooled coolant 111 can flow into the pipeline sheath 110 through the coolant pipeline 140 again to absorb the heat of the wire core 120, thereby forming a reciprocating heat dissipation, ensuring that the wire core 120 is always within a reliable temperature range, and ensuring the high efficiency of charging.

[0059] The pipeline connection part 131 and the end of the pipeline skin 110 are sealed, so that the coolant 111 stops flowing to one end of the joint 130 in the pipeline 1311, and no leakage occurs at the connection between the pipeline connection part 131 and the pipeline skin 110. The sealed connection can be achieved by hot melt connection, sealant bonding, sleeve connection and sealing clamping by a connection clip, etc., which is not limited here.

[0060] The connection between the pipe connection part 131 and the joint 130 can be as follows Figure 2 The one-piece structure shown in the figure can also be a split structure and sealed and connected to each other.

[0061] The connector 130 can be installed on the cabinet 200 by means of clamping, riveting, threaded fastener connection, etc., but it is necessary to ensure that the connector 130 is insulated from the cabinet 200 to ensure the safety of the charging pile. Specifically, in some embodiments, the connector 130 can be made of a conductive metal block, such as a copper block, an aluminum block, etc., which can not only ensure the transmission efficiency of the current, but also have good structural strength to ensure the structural stability when installed in the cabinet 200.

[0062] Regarding the protection of the pipeline sheath 110, specifically, after the joint 130 is installed along one side of the radial direction of the pipeline sheath 110 toward the cabinet 200, the pipeline sheath 110 is roughly vertical at the end connected to the pipeline connection part 131 under the action of its own gravity, that is, it extends roughly in the vertical direction. This arrangement can reduce the bending of the pipeline sheath 110 at the end connected to the cabinet 200, so that the pipeline sheath 110 and the internal wire core 120 are extended in a straight line, and there can be a certain gap between the two, reducing the risk of direct contact, reducing the thermal deformation of the pipeline sheath 110 caused by the heat of the wire core 120, and reducing the risk of rupture of the pipeline sheath 110, thereby avoiding leakage of the coolant 111. It should be noted that the extension direction of the end where the pipeline sheath 110 is connected to the cabinet 200 can extend vertically upward or downward, which is not limited here.

[0063] The end of the pipeline sheath 110 is connected to the conductive component 210 in the cabinet 200 through the joint 130, and the end of the pipeline sheath 110 extends in the vertical direction without bending. After the coolant 111 in the pipeline sheath 110 flows into the joint 130, the coolant 111 in the joint 130 needs to be sent to the heat dissipation component 220 in the cabinet 200. Figure 2 and 3 As shown in the present application, a coolant pipeline 140 is provided on the pipeline connection portion 131, which can be specifically as follows: Figure 5 As shown in the figure, an interface 1312 connected to the pipeline 1311 is arranged on the pipeline connecting part 131, and one end of the coolant pipeline 140 is sealed and connected to the interface 1312. The coolant pipeline 140 connects the interior of the pipeline sheath 110 with the heat dissipation component 220 through the pipeline 1311, so that the coolant 111 can flow between the pipeline sheath 110 and the heat dissipation component 220, thereby realizing reliable heat dissipation of the wire core 120.

[0064] In the charging gun pipeline installation assembly 100 provided in the embodiment of the present application, a connector 130 is provided at the end of the pipeline sheath 110, and the pipeline connecting part 131 on the connector 130 is connected to the pipeline sheath 110, and the connector 130 is electrically connected to the wire core 120, and the connector 130 is installed along one radial side of the pipeline sheath 110 toward the cabinet 200, so that the pipeline sheath 110 and the wire core 120 extend approximately in the same direction, reducing the bending of the pipeline sheath 110 and the wire core 120 inside it, maintaining a substantially uniform gap between the outer periphery of the wire core 120 and the pipeline sheath 110, reducing the probability of direct contact between the two, thereby reducing the risk of coolant leakage caused by rupture of the pipeline sheath 110. Furthermore, by providing a coolant pipeline 140 on the pipeline connecting portion 131 that is connected to the interior of the pipeline sheath 110 and the heat dissipation component 220 in the cabinet 200, the coolant 111 can flow between the interior of the pipeline sheath 110 and the heat dissipation component 220, thereby ensuring reliable heat dissipation of the wire core 120 by the coolant 111 and ensuring charging efficiency.

[0065] Considering that the distance between the connector and the conductive parts in the cabinet is relatively far, if the connector is inserted into the cabinet for a long distance and then connected to the conductive parts in the cabinet, it is inevitable that the volume of the connector needs to be set larger, which will affect the convenience of assembly. Figure 2 , and further combined with Figure 7 , Figure 7 The structural block diagram of the connection between the connector and the conductive component in the cabinet is shown in FIG. As shown in the figure, the connector 130 includes a conductive metal block 1301, and the conductive metal block 1301 is electrically connected to the wire core 120. The charging gun line installation assembly 100 also includes a soft copper bus 150, which is used to be at least partially disposed inside the cabinet 200 and connected between the conductive metal block 1301 and the conductive component 210, so that the conductive metal block 1301 is electrically connected to the conductive component 210 through the soft copper bus 150.

[0066] like Figure 2 As shown in the figure, connecting parts 151 can be provided at both ends of the soft copper busbar 150, the connecting part 151 at one end contacts and is fixedly connected to the conductive metal block 1301, and the connecting part 151 at the other end contacts and is fixedly connected to the conductive component 210 in the cabinet 200, so as to realize the electrical connection between the conductive metal block 1301 and the conductive component 210. Specifically, the connecting part 151 and the conductive metal block 1301 and the conductive component 210 can be fixed by rivets, threaded fasteners, welding, etc., and the electrical connection can be realized at the same time.

[0067] By setting a soft copper busbar 150, the conductive metal block 1301 is electrically connected to the conductive component 210 in the cabinet 200, thereby eliminating the need for a larger connector 130 to extend into the cabinet 200 to connect with the conductive component 210, thereby ensuring that the charging gun pipeline installation assembly 100 as a whole can be easily disassembled and assembled on the cabinet 200, facilitating the subsequent maintenance of the charging pile.

[0068] In order to improve the heat dissipation efficiency of the wire core, this application proposes an implementation method. Please refer to Figure 2 and Figure 8 The coolant pipeline 140 is a coolant output pipeline 141, and the coolant output pipeline 141 is used to supply the coolant that absorbs the heat of the wire core 120 in the pipeline skin 110 to the heat dissipation component 220. The charging gun pipeline installation assembly 100 also includes a coolant input pipeline 142, one end of which is used to communicate with the heat dissipation component 220, and the other end is connected to the pipeline skin 110. The coolant input pipeline 142 is used to supply the coolant after cooling in the heat dissipation component 220 to the pipeline skin 110.

[0069] The specific heat dissipation process is as follows: the low-temperature coolant in the heat dissipation component 220 enters the pipeline sheath 110 through the coolant input pipeline 142 to absorb the heat of the wire core 120. The temperature of the coolant that has absorbed the heat increases. The high-temperature coolant then enters the heat dissipation component 220 through the coolant output pipeline 141. After being cooled by the heat dissipation component 220, it enters the pipeline sheath 110 again to absorb the heat of the wire core 120, thereby forming a cycle.

[0070] The coolant is circulated between the heat dissipation component 220 and the pipeline skin 110 through the coolant input pipeline 142 and the coolant output pipeline 141 to improve the heat dissipation efficiency of the line core 120, thereby providing a guarantee for the charging efficiency.

[0071] It should be noted that, in some embodiments, the coolant output pipeline 141 can also be used to supply the coolant after cooling in the heat dissipation component 220 to the pipeline skin 110. Correspondingly, the coolant input pipeline is used to output the coolant that absorbs the heat of the wire core 120 in the pipeline skin 110 to the heat dissipation component 220.

[0072] Regarding the pipeline circuit structure, this application proposes an implementation method. Please refer to Figure 2 As shown in the figure, there are multiple pipeline sheaths 110, wire cores 120, connectors 130, coolant input pipelines 142 and coolant output pipelines 141, and each pipeline sheath 110, wire core 120, connector 130, coolant input pipeline 142 and coolant output pipeline 141 constitutes a group of lines, with a total of two groups of lines, one of which is a positive line and the other is a negative line.

[0073] By independently circulating heat for the positive and negative lines, that is, the positive and negative lines each have a set of coolant circulation systems, the wire cores 120 in the positive and negative lines can be cooled more efficiently.

[0074] Regarding the installation between the charging gun line and the cabinet, this application further proposes an implementation method. Please refer to the Figure 3 , and further combined with Figure 6 , Figure 6 As shown in the figure, the charging gun pipeline installation assembly 100 also includes a main pipeline sheath 160 and a pipeline connection seat 170. The main pipeline sheath 160 is wrapped on the two sets of pipeline sheaths 110. The pipeline connection seat 170 is sleeved on the main pipeline sheath 160, and the pipeline connection seat 170 is used to be fixedly connected to the cabinet 200.

[0075] Specifically, the pipeline connection seat 170 can be installed on the outer wall of the cabinet 200 by hanging, clamping, welding, threaded fastener connection, etc.

[0076] By wrapping the main pipeline sheath 160 around the two groups of pipeline sheaths 110, the two groups of lines are protected. By sleeved on the main pipeline sheath 160, the reliability of the connection between the pipeline connector 170 and the main pipeline sheath 160 can be ensured. After the pipeline connector 170 is assembled and fixed to the cabinet 200, it can be ensured that the part between the end of the pipeline sheath 110 connected to the connector 130 and the main pipeline sheath 160 can be extended in the vertical direction, ensuring that the pipeline sheath 110 at this part (that is, the end) and the wire core 120 will not come into direct contact due to bending.

[0077] In order to prevent the pipeline skin from being pulled and affecting its stability, the present application further proposes an implementation method. Please refer to Figure 6 As shown in the figure, the charging gun pipeline installation assembly 100 also includes a first pipe clamp 171 and a second pipe clamp 172, which are buckled and fixed to each other and sleeved on the outer periphery of the pipeline connection seat 170, and the first pipe clamp 171 is used to be fixedly connected to the cabinet 200, so that the pipeline connection seat 170 is fixed relative to the cabinet 200. The outer periphery of the pipeline connection seat 170 is provided with a first clamping portion 1701, and the first pipe clamp 171 and the second pipe clamp 172 are both provided with a second clamping portion 1712, and the first clamping portion 1701 and the second clamping portion 1712 are clamped to each other to limit the movement of the pipeline connection seat 170 relative to the first pipe clamp 171 and the second pipe clamp 172 in the axial direction and the rotation relative to the first pipe clamp 171 and the second pipe clamp 172 in the circumferential direction.

[0078] exist Figure 6 In the specific embodiment shown, the first clamping portion 1701 is a non-circular insert provided on the outer periphery of the pipeline connection seat 170, and the second clamping portion 1712 is a slot provided on the inner periphery of the first pipe clamp 171 and the second pipe clamp 172. When the first pipe clamp 171 and the second pipe clamp 172 are sleeved on the pipeline connection seat 170, the insert is respectively inserted into the slots on the first pipe clamp 171 and the second pipe clamp 172 to limit the pipeline connection seat 170 in the axial and circumferential directions at the same time. Of course, in other embodiments, the first clamping portion 1701 and the second clamping portion 1712 can also be a clamping fit between protrusions, a clamping fit between pins and holes, etc., which is not limited here.

[0079] like Figure 6 As shown in , a threaded hole 1711 may be provided on the side of the first pipe clamp 171 facing the second pipe clamp 172, and a through hole 1721 is correspondingly provided on the second pipe clamp 172. A threaded fastener passes through the through hole 1721 and is connected to the threaded hole 1711 on the first pipe clamp 171, thereby achieving assembly and fixation between the first pipe clamp 171 and the second pipe clamp 172. The first pipe clamp 171 may be assembled and fixed to the cabinet 200 on the side facing away from the second pipe clamp 172 by bonding, hanging, welding, threaded fastener connection, etc.

[0080] The following is a detailed description of the disassembly and assembly of the pipeline connection seat 170 on the cabinet 200:

[0081] When installing the pipeline connection seat 170 on the cabinet 200, the first pipe clamp 171 can be fixed to the cabinet first, and then the first clamping portion 1701 and the second clamping portion 1712 on the first pipe clamp 171 are clamped together, so that the pipeline connection seat 170 is pre-positioned on the first pipe clamp 171, and then the second clamping portion 1712 on the second pipe clamp 172 is clamped together with the first clamping portion 1701. At this time, the second pipe clamp 172 and the first pipe clamp 171 are buckled together and sleeved on the pipeline connection seat 170. Then, the second pipe clamp 172 and the first pipe clamp 171 are assembled and fixed to complete the installation of the pipeline connection seat 170 on the cabinet 200.

[0082] When the pipeline connection seat 170 needs to be disassembled, the pipeline connection seat 170 can be easily removed by simply removing the second pipe clamp 172 from the first pipe clamp 171 without removing the first pipe clamp 171, which is convenient and quick to operate.

[0083] By providing a first pipe clamp 171 and a second pipe clamp 172 that are interlocked and sleeved on the pipeline connecting seat 170, the pipeline connecting seat 170 can be easily disassembled and assembled on the cabinet 200, and the clamping cooperation between the second clamping part 1712 on the first pipe clamp 171 and the second pipe clamp 172 and the first clamping part 1701 on the pipeline connecting seat 170 can ensure that the pipeline connecting seat 170 will not move easily, thereby ensuring the overall stability and safety of the charging gun pipeline.

[0084] For the assembly of the joint and the cabinet, this application proposes an implementation method. Please refer to Figure 2 As shown in the figure, the charging gun pipeline installation assembly 100 also includes a base 180, and the connector 130 and the coolant pipeline 140 are at least partially accommodated in the base 180. The base 180 is used to be fixedly connected to the cabinet 200, and at the same time covers the outside of the connector 130 and the coolant pipeline 140.

[0085] For details, please continue to see Figure 2 , and further combined with Fig. 9 , Fig. 9 The structure of the charging gun pipeline installation assembly from another perspective is shown in the figure. As shown in the figure, the base 180 can be a box-shaped structure with an opening 181 on one side facing the cabinet 200, and an inlet 182 is opened at the bottom adjacent to the side where the opening 181 is located. After the connector 130 and the pipeline skin 110 extend into the base 180 from the inlet 182, the coolant pipeline 140 is connected to the pipeline skin 110. The connector 130 can be fixed in the base 180 by pouring glue in the base 180. Of course, it can be fixed by snap-on connection, threaded fastener connection, etc., which is not limited here. The connector 130 is exposed at the opening 181, so that the connector 130 is electrically connected to the conductive component 210 in the cabinet 200 through the opening 181 and the installation opening 230 on the cabinet 200, and the coolant pipeline 140 passes through the opening 181 and the installation opening 230 on the cabinet 200 to connect to the heat dissipation component 220 in the cabinet 200.

[0086] Furthermore, if Fig. 9 As shown in , for an embodiment including a positive electrode circuit and a negative electrode circuit, a separator 183 may be provided in the base 180 to insulate the connector 130 of the positive electrode circuit and the connector 130 of the negative electrode circuit from each other. For an embodiment in which a pipeline connection seat 170 is provided, one end of the pipeline connection seat 170 facing the connector 130 may be riveted or clamped to an inlet 182 of the base 180, so that the pipeline connection seat 170 closes the inlet 182, thereby improving the stability and safety of the internal circuit structure.

[0087] Furthermore, if Figure 2 and Fig. 9As shown in FIG. 1 , a connecting plate 184 may be provided at the edge of the base 180 , and the connecting plate 184 is attached to the wall of the cabinet 200 and fixedly connected to the cabinet 200 by means of threaded fasteners or the like.

[0088] By at least partially accommodating the connector 130 and the coolant pipeline 140 in the base 180, and fixing the base 180 to the cabinet 200 while covering the outer circumference of the connector 130 and the coolant pipeline 140, not only is it easy to assemble the connector 130 on the cabinet 200, but the base 180 can also protect the connector 130 and the coolant pipeline 140, thereby ensuring the safety and reliability of the charging pile.

[0089] In order to improve the airtightness of the interior of the base 180, the present application further proposes an implementation method. Fig. 9 As shown in the figure, a sealing gasket 185 is provided on one side of the base 180 for fixed connection with the cabinet 200. The sealing gasket 185 is used to be clamped between the base 180 and the cabinet 200 to seal the assembly gap between the base 180 and the cabinet 200.

[0090] Specifically, the sealing gasket 185 can be made of foam, soft rubber or other materials. By being clamped between the base 180 and the cabinet 200 when they are in contact and deforming accordingly, the assembly gap between the base 180 and the cabinet 200 is sealed, thereby ensuring the airtightness of the internal space of the base 180 and providing environmental protection for the operation of the wire core 120, the connector 130 and the coolant pipeline 140.

[0091] Considering that after the base 180 and the cabinet 200 are assembled, the corresponding assembly parts on the base 180 will inevitably be exposed, which not only affects the aesthetics, but also in bad weather conditions, such as dust, rainstorms, etc., the base 180 and the assembly parts thereon are easily affected, causing the structural stability of the base 180 to decrease. Based on this, the present application further proposes an implementation method, please refer to the detailed description again. Figure 2 and Fig. 9 As shown in the figure, the charging gun line installation assembly 100 also includes a protective shell 190, and the protective shell 190 covers the base 180. By covering the protective shell 190 on the base 180, the base 180 is covered and protected as a whole to ensure the structural stability of the base 180.

[0092] According to another aspect of the embodiment of the present application, a charging pile is provided. Figure 2 , the figure shows a partial structure of the charging pile provided in the embodiment of the present application. As shown in the figure, the charging pile 500 includes a cabinet 200 and a charging gun line installation assembly 100 in any of the above embodiments, and the charging gun line installation assembly 100 is installed on the cabinet 200.

[0093] The charging pile 500 provided in the embodiment of the present application adopts the charging gun pipeline installation assembly 100 in the above embodiment, which can ensure that the pipeline sheath 110 and the wire core 120 inside the charging gun pipeline installation assembly 100 do not need to be bent, thereby avoiding the problem of coolant leakage caused by rupture of the pipeline sheath 110, and at the same time ensure that the coolant can reliably dissipate heat to the wire core 120, thereby ensuring charging efficiency.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
