Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of charging equipment, and in particular, to a charging gun and a charging equipment. BACKGROUND

[0002] The charging gun is a connecting device for transmitting electric energy from a charging pile to an electric vehicle. After the charging gun is plugged into the electric vehicle, the charging pile can charge the electric vehicle through the charging gun. With the rapid development of the electric vehicle industry, the battery capacity of the electric vehicle is becoming larger and larger. Increasing the charging power to shorten the charging time is a method to achieve fast charging. After the charging power is increased, the heat consumption of the charging gun increases, and the high temperature of the charging gun can affect the reliability and other performances of the charging gun. Therefore, the heat dissipation efficiency of the charging gun restricts the increase of the charging power.

[0003] Liquid cooling of the charging gun is a direction to improve the heat dissipation efficiency of the charging gun. However, the temperature of the end of the power line of the charging gun connected to the power supply component of the charging pile is often high, which limits the increase of the charging power of the charging gun. CONTENT OF THE INVENTION

[0004] Embodiments of the present application provide a charging gun and a charging equipment, which can make the heat dissipation effect of the end of the power line of the charging gun connected to the power supply component of the charging pile better, and be beneficial to increasing the charging power of the charging gun.

[0005] The first aspect of the embodiments of the present application provides a charging gun, which comprises a gun head, a cable, a heat conduction member and a fixing sleeve. The cable is connected to the gun head, and the cable comprises a power line and a liquid cooling pipe. The heat conduction member is arranged at one end of the cable away from the gun head, and the surface of the heat conduction member has a wire groove and a pipe groove. The power line is arranged in the wire groove, and the liquid cooling pipe is arranged in the pipe groove. The fixing sleeve is arranged outside the heat conduction member, the power line and the liquid cooling pipe, and the fixing sleeve press-bonds the power line and the liquid cooling pipe on the heat conduction member.

[0006] The charging gun provided by the embodiments of the present application is characterized in that the end of the power line connected to the power supply component and the liquid cooling pipe are press-bonded on the heat conduction member. The heat of the end of the power line connected to the power supply component can be conducted to the liquid cooling pipe through the heat conduction member, so that the liquid cooling pipe can efficiently dissipate heat from the end of the power line away from the gun head, which is beneficial to reducing the temperature of the end of the power line connected to the power supply component, and further beneficial to increasing the charging power of the charging gun.

[0007] In addition, the power line and the liquid cooling pipe are crimped on the heat conduction piece by the fixing sleeve to achieve heat dissipation of the one end of the power line connecting the power supply assembly by the liquid cooling pipe. While the liquid cooling pipe can efficiently dissipate heat from the one end of the power line connecting the power supply assembly, the liquid cooling pipe and the power line achieve assembly of a small number of components and a simple structure, so that the components for assembly of the liquid cooling pipe and the power line are easy to process and have low cost, and the components of the one end of the charging gun connecting the power supply assembly are also easy to assemble, thereby achieving efficient heat dissipation of the one end of the power line connecting the power supply assembly by the liquid cooling pipe at low cost.

[0008] In addition, the power line and the liquid cooling pipe are crimped on the heat conduction piece by the fixing sleeve to achieve heat dissipation of the one end of the power line connecting the power supply assembly by the liquid cooling pipe. While the liquid cooling pipe can efficiently dissipate heat from the one end of the power line connecting the power supply assembly, the liquid cooling pipe and the power line achieve assembly of a small number of components and a simple structure, so that the components for assembly of the liquid cooling pipe and the power line are easy to process and have low cost, and the components of the one end of the charging gun connecting the power supply assembly are also easy to assemble, thereby achieving efficient heat dissipation of the one end of the power line connecting the power supply assembly by the liquid cooling pipe at low cost.

[0009] Furthermore, the power line is arranged in the wire slot, which can limit the position of the power line, so that the power line and the heat conduction piece have good assembly stability and reliable contact. In addition, the wire slot can also increase the contact area between the power line and the heat conduction piece, which is beneficial to heat transfer between the power line and the heat conduction piece, thereby facilitating heat dissipation of the one end of the power line away from the gun head by the liquid cooling pipe. The liquid cooling pipe is arranged in the pipe slot, which can limit the position of the liquid cooling pipe, so that the liquid cooling pipe and the heat conduction piece have good assembly stability and reliable contact. In addition, the pipe slot can also increase the contact area between the liquid cooling pipe and the heat conduction piece, which is beneficial to heat transfer between the liquid cooling pipe and the heat conduction piece, thereby facilitating heat dissipation of the one end of the power line away from the gun head by the liquid cooling pipe.

[0010] For example, the wire slot and the pipe slot can be located on the same side surface of the heat conduction piece, or the wire slot and the pipe slot can be located on different side surfaces of the heat conduction piece.

[0011] For example, the fixing sleeve can be a conductive sleeve or an insulating sleeve. For example, the fixing sleeve can be a heat shrinkable sleeve.

[0012] The heat conduction piece includes a first end surface and a second end surface, and the first end surface and the second end surface are located at both ends of the extension direction of the heat conduction piece.

[0013] In some possible embodiments, one end of the pipe groove penetrates through the first end face, and the other end of the pipe groove penetrates through the second end face. In this way, the liquid cooling pipe can be inserted into the pipe groove from the first end face and taken out of the pipe groove from the second end face, so that the liquid cooling pipe is easier to be arranged in the pipe groove, and the liquid cooling pipe is easier to be assembled with the heat conduction member. In addition, the contact area between the liquid cooling pipe and the heat conduction member can be larger, so that the heat conduction area between the liquid cooling pipe and the heat conduction member is larger, and the liquid cooling pipe is more efficient in heat dissipation of the power line. In addition, the fixing sleeve is also beneficial to the wrapping and protection of the liquid cooling pipe.

[0014] In some possible embodiments, one end of the wire groove penetrates through the first end face. In this way, the power line can be inserted into the wire groove from the first end face, so that the power line is easier to be arranged in the wire groove, and the power line is easier to be assembled with the heat conduction member. In addition, the contact area between the power line and the heat conduction member can be larger, so that the heat conduction area between the power line and the heat conduction member is larger, and the liquid cooling pipe is more efficient in heat dissipation of the power line. In addition, the fixing sleeve is also beneficial to the wrapping and protection of one end of the power line connected to the power supply assembly.

[0015] For example, the end of the wire groove away from the first end face can penetrate through the second end face, or the end of the wire groove away from the first end face can also be a closed structure.

[0016] In some possible embodiments, the size of the heat conduction member in the extension direction thereof is greater than the width of the heat conduction member. In this way, the length of the part of the heat conduction member, the power line and the liquid cooling pipe covered by the fixing sleeve can be longer, so that the power line and the liquid cooling pipe are more stably crimped on the heat conduction member.

[0017] In some possible embodiments, the surface of the heat conduction member has a plurality of pipe grooves, and the plurality of pipe grooves are arranged at intervals along the width direction of the heat conduction member. In this way, the plurality of liquid cooling pipes can be arranged on the heat conduction member. When the plurality of liquid cooling pipes are arranged on the heat conduction member, the heat conduction member can limit the positions of the plurality of liquid cooling pipes through the groove walls of the plurality of pipe grooves, so that the assembly stability of the heat conduction member and the plurality of liquid cooling pipes is better, and the contact is more reliable. In addition, when the plurality of liquid cooling pipes are arranged on the heat conduction member, the heat conduction member can be in contact with the plurality of liquid cooling pipes through the groove walls of the plurality of pipe grooves, so that the contact area between the heat conduction member and the plurality of liquid cooling pipes is larger, the heat conduction area between the heat conduction member and the plurality of liquid cooling pipes is larger, and the power line is more efficient in heat dissipation through the plurality of liquid cooling pipes.

[0018] In some possible implementation manners, the first end surface is located at one end of the heat conduction member close to the gun head along the extension direction of the cable, and the second end surface is located at one end of the heat conduction member away from the gun head along the extension direction of the cable. The plurality of pipe grooves include adjacent first pipe grooves and second pipe grooves. When one end of the pipe groove penetrates through the first end surface and the other end of the pipe groove penetrates through the second end surface, the distance between the end of the first pipe groove penetrating through the first end surface and the end of the second pipe groove penetrating through the first end surface in the width direction of the heat conduction member is smaller than the distance between the end of the first pipe groove penetrating through the second end surface and the end of the second pipe groove penetrating through the second end surface in the width direction of the heat conduction member. In this way, the part of the first liquid cooling pipe located outside the second end surface and penetrating through the first pipe groove is separated from the part of the second liquid cooling pipe located outside the second end surface and penetrating through the second pipe groove, so as to form a mounting space for avoiding other components such as bolts, so that the liquid cooling pipe is not easily damaged by contacting the bolt or other components when the bolt or other components are mounted to the side of the second end surface away from the first end surface.

[0019] In some possible implementation manners, the width of the heat conduction member at the end where the first end surface is located is smaller than the width of the heat conduction member at the end where the second end surface is located. In this way, while facilitating the realization that the distance between the end of the first pipe groove penetrating through the first end surface and the end of the second pipe groove penetrating through the first end surface in the width direction of the heat conduction member is smaller than the distance between the end of the first pipe groove penetrating through the second end surface and the end of the second pipe groove penetrating through the second end surface in the width direction of the heat conduction member, the width of the end of the heat conduction member close to the gun head can be smaller, which is beneficial to saving installation space and facilitating the assembly of the heat conduction member.

[0020] In some possible implementation manners, the heat conduction member includes a first surface and a second surface, the first surface and the second surface are respectively located at two sides in the thickness direction of the heat conduction member, the wire groove is located on the first surface, and the pipe groove is located on the second surface. The thickness of the heat conduction member is smaller than the width of the heat conduction member. In this way, the wire groove and the pipe groove are arranged on the two side surfaces in the thickness direction of the heat conduction member, which is beneficial to arranging the wire groove and the pipe groove on the heat conduction member with a smaller size, in other words, beneficial to reducing the size of the heat conduction member provided with the wire groove and the pipe groove. In addition, the wire groove and the pipe groove are respectively located on the two side surfaces in the thickness direction of the heat conduction member, so that the power line and the liquid cooling pipe are respectively located on the two sides in the thickness direction of the heat conduction member, and the fixing sleeve exerts pressure on the two sides in the thickness direction of the heat conduction member through the power line and the liquid cooling pipe, which is beneficial to stably pressing the power line and the liquid cooling pipe on the heat conduction member. In addition, the power line and the liquid cooling pipe are respectively located on the two sides in the thickness direction of the heat conduction member, so that the power line and the liquid cooling pipe are not easily interfered with each other, and the wiring is relatively easy. In addition, the thickness of the heat conduction member is smaller than the width of the heat conduction member, so that the heat transfer path between the end of the power line connected to the power supply assembly and the liquid cooling pipe is relatively short, which is beneficial to the liquid cooling pipe to more efficiently dissipate heat from the end of the power line connected to the power supply assembly.

[0021] In some possible embodiments, the charging gun further comprises an electrically conductive member. The electrically conductive member is arranged on the side of the heat-conducting member having the wire slot, and is fixed to and electrically connected with the power wire. Part of the electrically conductive member is sleeved in the fixing sleeve, and the fixing sleeve crimps the electrically conductive member to at least one of the heat-conducting member and the power wire, so as to fix the electrically conductive member to the heat-conducting member. In this way, by arranging the electrically conductive member, the electric connection between the power wire and the power supply assembly is facilitated. In addition, the electric connection between the power wire and the power supply assembly is achieved through the electrically conductive member, and the material of the heat-conducting member can be an insulating material, which can reduce the requirements for the material selection of the heat-conducting member. In addition, part of the electrically conductive member is sleeved in the fixing sleeve, and the fixing sleeve crimps the electrically conductive member to at least one of the heat-conducting member and the power wire, so that environmental factors such as vibration are less likely to cause the assembly of the electrically conductive member, the power wire and the heat-conducting member to loosen, the assembly of the electrically conductive member, the power wire and the heat-conducting member is more stable, the contact is more reliable, and in turn, problems such as an increase in the contact resistance of the end of the power wire away from the gun head and an increase in heat consumption due to the loosening of the assembly of the electrically conductive member, the power wire and the heat-conducting member are less likely to occur.

[0022] In some possible embodiments, the wire slot comprises a first slot section and a second slot section, one end of the first slot section penetrates through the end face of the first end of the heat-conducting member, and the other end of the first slot section is in communication with the second slot section. The fixing sleeve crimps the electrically conductive member to the heat-conducting member, and the part of the electrically conductive member crimped to the heat-conducting member is located at the second slot section, and the slot cavity width of the second slot section is greater than the slot cavity width of the first slot section. In this way, the slot cavity of the first slot section for accommodating the power wire is narrow, which facilitates the power wire to partially protrude from the surface of the heat-conducting member at the first slot section to contact the fixing sleeve, and facilitates the fixing sleeve to crimp the power wire to the heat-conducting member at the first slot section. The slot cavity of the second slot section for accommodating the power wire is relatively wide, which facilitates the electrically conductive member to flatten the power wire at the second slot section, so that the electrically conductive member can be more stably crimped to the heat-conducting member, thereby facilitating the stable assembly of the electrically conductive member and the heat-conducting member.

[0023] In some possible embodiments, the electrically conductive member comprises a first part and a second part connected with each other. The first part is sleeved in the fixing sleeve, and the fixing sleeve crimps the first part to at least one of the heat-conducting member and the power wire, and the second part is located outside the fixing sleeve. The second part protrudes from the surface of the side of the first part away from the heat-conducting member, and the thickness of the part of the second part protruding from the surface of the side of the first part away from the heat-conducting member is greater than or equal to the wall thickness of the fixing sleeve. In this way, when the electrically conductive member is assembled with the connecting copper bar and the like, the second part protruding can contact the connecting copper bar and the like, so that a space for accommodating the fixing sleeve can be formed between the surface of the side of the first part away from the heat-conducting member and the connecting copper bar and the like, so that the electrically conductive member is less likely to be lifted by the contact between the fixing sleeve and the connecting copper bar and the like, thereby facilitating the stable assembly of the electrically conductive member and the connecting copper bar and the like.

[0024] In some possible implementations, the conductive element has a connection hole. In the width direction of the heat-conducting element, the connection hole is located between one end of the first tube groove penetrating the second end face and one end of the second tube groove penetrating the second end face. This allows for the first and second liquid cooling tubes to be spaced apart on the side of the second end face away from the first end face to allow for the installation of fasteners connecting the conductive element. This facilitates the avoidance of the fasteners connecting the conductive element by the portions of the first and second liquid cooling tubes located outside the second end face. While facilitating the connection of the conductive elements, it also prevents the first and second liquid cooling tubes from being damaged by contact with the fasteners connecting the conductive elements.

[0025] A second aspect of this application provides a charging device, which includes a charging pile and a charging gun as described in any of the above embodiments. The charging pile includes a power supply component and a liquid supply component. One end of the power line of the charging gun is electrically connected to the gun head, and the other end of the power line is electrically connected to the power supply component. One end of the liquid cooling pipe of the charging gun is connected to the gun head, and the other end of the liquid cooling pipe is connected to the liquid supply component.

DETAILED DESCRIPTION

[0047] The terms used in the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application, and the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0048] Figure 1 A schematic view of a charging device provided in an embodiment of the present application.

[0049] AsFigure 1 As shown in the illustration, this application provides a charging device for charging electric vehicles. The charging device includes a charging pile 20 and a charging gun 10, with the charging pile 20 connected to the charging gun 10. The charging pile 20 provides electrical energy, and the charging gun 10 is a connection device that transmits electrical energy from the charging pile 20 to the electric vehicle. After the charging gun 10 is plugged into the electric vehicle, the charging pile 20 can charge the electric vehicle through the charging gun 10.

[0050] The charging gun 10 includes a gun head 100 and a cable 200, with both ends of the cable 200 connected to the gun head 100 and the charging station 20, respectively. The charging station 20 includes a power supply component 21, which can be electrically connected to the mains power supply through a charging host. The charging host can convert the current supplied by the mains power supply into the current required for charging the electric vehicle.

[0051] Figure 2 This is an explosion diagram of the end of a charging gun furthest from the gun head, provided as an embodiment of this application.

[0052] like Figure 2 As shown, and see Figure 1 The cable 200 includes a power cable 210, which includes a power wire 211 and an insulation layer (not shown) covering the outside of the power wire 211. Both ends of the power wire 211 extend out of the insulation layer. One end of the power wire 211 is electrically connected to the gun head 100, and the other end of the power wire 211 away from the gun head 100 is electrically connected to the power supply component 21.

[0053] The nozzle 100 includes a power terminal (not shown), and a power line 211 is electrically connected to the power terminal. For example, the power line 211 can be connected to the power terminal by soldering, fastener connection, or other methods.

[0054] For example, the power supply component 21 has a connecting copper busbar (not shown), and the power line 211 is electrically connected to the connecting copper busbar, such that the power line 211 is electrically connected to the power supply component 21 through the connecting copper busbar.

[0055] For example, the gun head 100 includes two power terminals, the cable 200 includes at least two power cables 210, and the power supply assembly 21 includes two connecting copper busbars, wherein one power terminal is electrically connected to one connecting copper busbar via a power line 211 of at least one power cable 210, and the other power terminal is electrically connected to another connecting copper busbar via a power line 211 of another at least one power cable 210.

[0056] For example, one of the two power terminals is a positive power terminal, and the other is a negative power terminal. One of the two connecting copper bars is a positive copper bar, and the other is a negative copper bar. The positive power terminal is electrically connected to the positive copper bar through the power line 211 of the at least one power cable 210. The negative power terminal is electrically connected to the negative copper bar through the power line 211 of the at least one power cable 210. The positive copper bar is electrically connected to the positive electrode of the power supply assembly 21. The negative copper bar is electrically connected to the negative electrode of the power supply assembly 21. The power cable 210 connecting the positive power terminal and the positive copper bar is a positive power cable. The power cable 210 connecting the negative power terminal and the negative copper bar is a negative power cable.

[0057] For example, the cable 200 further includes an outer sheath layer 220 covering the outside of the power cable 210. The outer sheath layer 220 can provide mechanical protection, insulation protection, and the like. Both ends of the power cable 210 pass through the outer sheath layer 220.

[0058] For example, the cable 200 can further include a signal cable, a grounding cable, and a filler (not shown). The outer sheath layer 220 covers the outside of the signal cable, the grounding cable, and the filler. The filler is used to fill the gap in the outer sheath layer 220. Both ends of the signal cable and the grounding cable pass through the outer sheath layer 220. The grounding cable is used to realize the grounding of the gun head 100 and the cable 200. The signal cable is used to realize the signal interaction between the gun head 100 and the charging pile 20.

[0059] In order to improve the heat dissipation efficiency of the charging gun 10, the cable 200 further includes a liquid cooling pipe 212 sleeved in the outer sheath layer 220. The charging pile 20 can further include a liquid supply assembly 22. One end of the liquid cooling pipe 212 is connected to the gun head 100. The other end of the liquid cooling pipe 212 away from the gun head 100 is connected to the liquid supply assembly 22. The liquid supply assembly 22 is used to supply cooling liquid to the liquid cooling pipe 212. The liquid cooling pipe 212 is used to transport the cooling liquid from the liquid supply assembly 22 to the gun head 100 to realize liquid cooling heat dissipation of the gun head 100.

[0060] For example, the liquid cooling pipe 212 can be in contact with the power line 211. The liquid cooling pipe 212 can realize liquid cooling heat dissipation of the power line 211.

[0061] In some examples, the power cable 210 can include the liquid cooling pipe 212. The power line 211 is covered on the surface of the liquid cooling pipe 212. The insulating layer is covered on the surface of the power line 211. Both ends of the liquid cooling pipe 212 pass through the insulating layer.

[0062] In some examples, the gun head 100 can further include a liquid cooling assembly (not shown). The liquid cooling pipe 212 is connected to the liquid cooling assembly. The liquid cooling assembly can be in contact with the power terminal. The liquid cooling assembly can realize heat dissipation of the power terminal to realize liquid cooling heat dissipation of the gun head 100.

[0063] For example, cable 200 includes at least two liquid-cooled pipes 212, at least one of which is an inlet liquid-cooled pipe and at least one of which is a return liquid-cooled pipe. For instance, one power cable 210 of cable 200 may include an inlet liquid-cooled pipe 212, and another power cable 210 of cable 200 may include a return liquid-cooled pipe 212. One end of the inlet liquid-cooled pipe is connected to the outlet end of the liquid supply assembly 22, and the other end is connected to the inlet end of the liquid cooling assembly. One end of the return liquid-cooled pipe is connected to the outlet end of the liquid cooling assembly, and the other end is connected to the return end of the liquid supply assembly 22.

[0064] Figure 3 This is a schematic diagram from one perspective of a heat-conducting component provided in an embodiment of this application. Figure 4 for Figure 3 The diagram shows another perspective of the heat-conducting component provided. In the diagram, the x-direction is the extension direction of the heat-conducting component 300, the y-direction is the width direction of the heat-conducting component 300, and the z-direction is the thickness direction of the heat-conducting component 300.

[0065] like Figure 3 , Figure 4 As shown, and refer to Figure 2 In this embodiment of the application, the charging gun 10 further includes a heat-conducting component 300, which is disposed at the end of the cable 200 away from the gun head 100. The surface of the heat-conducting component 300 has a wire groove 310 and a tube groove 320.

[0066] For example, the heat-conducting element 300 is located at the end of the power line 211 away from the nozzle 100.

[0067] For example, the wire groove 310 and the pipe groove 320 can be located on the same side of the surface of the heat conductor 300, or the wire groove 310 and the pipe groove 320 can be located on different sides of the surface of the heat conductor 300.

[0068] Figure 5 This is a schematic diagram from one perspective illustrating the interaction between a cable and a heat-conducting component, provided as an embodiment of this application. Figure 6 for Figure 5 This is a schematic diagram from another perspective showing the interaction between the cable and the heat-conducting component.

[0069] like Figure 5 , Figure 6 As shown, the power line 211 is threaded through the wire groove 310, and the liquid cooling pipe 212 is threaded through the pipe groove 320.

[0070] Figure 7 This is a schematic diagram of a charging gun located away from the gun head, as provided in an embodiment of this application.

[0071] like Figure 7As shown, the charging gun 10 further includes a fixing sleeve 400 sleeved outside the heat conduction member 300, the power line 211 and the liquid cooling pipe 212, and the fixing sleeve 400 crimps the power line 211 and the liquid cooling pipe 212 on the heat conduction member 300, so that the power line 211 and the liquid cooling pipe 212 are in contact with the heat conduction member 300.

[0072] In this way, compared with the scheme that the one end of the power line 211 connected to the power supply assembly 21 is bifurcated after the liquid cooling pipe 212 and then is welded on the connecting copper bar, the one end of the power line 211 connected to the power supply assembly 21 is crimped on the heat conduction member 300, and after the one end of the power line 211 connected to the power supply assembly 21 and the liquid cooling pipe 212 are in contact with the heat conduction member 300, the heat of the one end of the power line 211 connected to the power supply assembly 21 can be conducted to the liquid cooling pipe 212 through the heat conduction member 300, so that the liquid cooling pipe 212 can more efficiently dissipate heat from the one end of the power line 211 away from the gun head 100, which is conducive to reducing the temperature of the one end of the power line 211 connected to the power supply assembly 21, and further conducive to improving the charging power of the charging gun 10.

[0073] In addition, the heat dissipation of the one end of the power line 211 connected to the power supply assembly 21 by the liquid cooling pipe 212 is realized by crimping the power line 211 and the liquid cooling pipe 212 on the heat conduction member 300 through the fixing sleeve 400 so that the power line 211 and the liquid cooling pipe 212 are in contact with the heat conduction member 300, and while the liquid cooling pipe 212 can more efficiently dissipate heat from the one end of the power line 211 connected to the power supply assembly 21, the number of components required for assembly between the liquid cooling pipe 212 and the power line 211 is less and the structure is simpler, so that the assembly of the components of the liquid cooling pipe 212 and the power line 211 is easier to process and has lower cost, and the assembly of the components of the one end of the charging gun 10 connected to the power supply assembly 21 is also easier, and thus the cost of realizing the more efficient heat dissipation of the one end of the power line 211 connected to the power supply assembly 21 by the liquid cooling pipe 212 is lower.

[0074] In addition, the heat dissipation of the one end of the power line 211 connected to the power supply assembly 21 by the liquid cooling pipe 212 is realized by crimping the power line 211 and the liquid cooling pipe 212 on the heat conduction member 300 through the fixing sleeve 400 so that the power line 211 and the liquid cooling pipe 212 are in contact with the heat conduction member 300, and while the liquid cooling pipe 212 can more efficiently dissipate heat from the one end of the power line 211 connected to the power supply assembly 21, the number of components required for assembly between the liquid cooling pipe 212 and the power line 211 is less and the structure is simpler, so that the assembly of the components of the liquid cooling pipe 212 and the power line 211 is easier to process and has lower cost, and the assembly of the components of the one end of the charging gun 10 connected to the power supply assembly 21 is also easier, and thus the cost of realizing the more efficient heat dissipation of the one end of the power line 211 connected to the power supply assembly 21 by the liquid cooling pipe 212 is lower.

[0075] Further, the power line 211 is arranged in the wire groove 310. The wire groove 310 can limit the position of the power line 211, so that the power line 211 and the heat conduction member 300 are assembled stably and reliably. In addition, the wire groove 310 can increase the contact area between the power line 211 and the heat conduction member 300, so as to facilitate the heat transfer between the power line 211 and the heat conduction member 300, and further facilitate the heat dissipation of the liquid cooling pipe 212 to the end of the power line 211 away from the gun head 100. The liquid cooling pipe 212 is arranged in the pipe groove 320. The pipe groove 320 can limit the position of the liquid cooling pipe 212, so that the liquid cooling pipe 212 and the heat conduction member 300 are assembled stably and reliably. In addition, the pipe groove 320 can increase the contact area between the liquid cooling pipe 212 and the heat conduction member 300, so as to facilitate the heat transfer between the liquid cooling pipe 212 and the heat conduction member 300, and further facilitate the heat dissipation of the liquid cooling pipe 212 to the end of the power line 211 away from the gun head 100.

[0076] The fixing sleeve 400 is pressed on the groove wall of the wire groove 310, so that the power line 211 is in contact with the groove wall of the wire groove 310. The fixing sleeve 400 is pressed on the groove wall of the pipe groove 320, so that the liquid cooling pipe 212 is in contact with the groove wall of the pipe groove 320. In addition to the fixing function, the fixing sleeve 400 can also protect the components such as the liquid cooling pipe 212 and the power line 211 arranged in the fixing sleeve 400.

[0077] For example, the liquid cooling pipe 212 arranged in the pipe groove 320 can be a liquid inlet pipe or a liquid return pipe.

[0078] For example, the end of the insulating layer away from the gun head 100 can be arranged in the fixing sleeve 400, so as to protect the liquid cooling pipe 212 and the power line 211.

[0079] For example, the end of the power line 211 away from the gun head 100 can be arranged in the wire groove 310.

[0080] In some possible embodiments, the heat conduction member 300 is made of an electrically conductive material, for example, copper, aluminum or other metal. The power line 211 is electrically connected with the heat conduction member 300. The end of the heat conduction member 300 away from the gun head 100 along the extension direction of the cable 200 is arranged out of the fixing sleeve 400. The part of the heat conduction member 300 arranged out of the fixing sleeve 400 can be fixed with the connection copper bar and electrically connected, so as to realize the electrical connection between the power line 211 and the power supply assembly 21. For example, the heat conduction member 300 can be connected with the connection copper bar by welding, fastener connection or other methods.

[0081] For example, the liquid cooling pipe 212 arranged in the pipe groove 320 can be a liquid inlet pipe or a liquid return pipe. Figures 5-7As shown, in some other possible embodiments, the charging gun 10 further comprises an electrically-conductive member 500, which is arranged on the side of the heat-conducting member 300 having the wire slot 310, and is fixed and electrically connected with the power line 211. Part of the electrically-conductive member 500 is sleeved in the fixing sleeve 400, the fixing sleeve 400 crimps the electrically-conductive member 500 on at least one of the heat-conducting member 300 and the power line 211, so as to fix the electrically-conductive member 500 with the heat-conducting member 300, and part of the electrically-conductive member 500 outside the fixing sleeve 400 is electrically connected with the power supply assembly 21. Specifically, the part of the electrically-conductive member 500 outside the fixing sleeve 400 can be fixed and electrically connected with the connecting copper bar. For example, the electrically-conductive member 500 can be connected with the connecting copper bar by welding, fastener connection or the like.

[0082] In this way, by arranging the electrically-conductive member 500, the electric connection between the power line 211 and the power supply assembly 21 is facilitated. In addition, the electric connection between the power line 211 and the power supply assembly 21 is realized through the electrically-conductive member 500, and the material of the heat-conducting member 300 can be an insulating material, so that the requirement for the material of the heat-conducting member 300 can be reduced. In addition, part of the electrically-conductive member 500 is sleeved in the fixing sleeve 400, and the fixing sleeve 400 crimps the electrically-conductive member 500 on at least one of the heat-conducting member 300 and the power line 211, so that environmental factors such as vibration are less likely to cause the assembly of the electrically-conductive member 500, the power line 211 and the heat-conducting member 300 to loosen, and the assembly of the electrically-conductive member 500, the power line 211 and the heat-conducting member 300 is stable and reliable in contact, so that problems such as the increase of the contact resistance of the end of the power line 211 away from the gun head 100 and the increase of the heat loss caused by the loosening of the assembly of the electrically-conductive member 500, the power line 211 and the heat-conducting member 300 are less likely to occur.

[0083] For example, the electrically-conductive member 500 can be fixed with the power line 211 by welding.

[0084] In the example in which the charging gun 10 comprises the electrically-conductive member 500, the heat-conducting member 300 can be an insulating member or an electrically-conductive member. The material of the heat-conducting member 300 can comprise one or more of the following: metal, ceramic, heat-conducting polymer, etc. For example, the heat-conducting member 300 can be made of aluminum or aluminum alloy.

[0085] In some examples, the fixing sleeve 400 can be an insulating sleeve, for example, the material of the fixing sleeve 400 can be plastic.

[0086] In this way, the fixing sleeve 400 can play a role of insulation protection.

[0087] For example, the fixing sleeve 400 can be a heat shrink tubing, which allows the fixing sleeve 400 to provide insulation protection while also ensuring a more secure and convenient crimping of the heat-conducting component 300, power line 211, liquid cooling pipe 212, and conductive component 500.

[0088] In other examples, the retaining sleeve 400 can be a conductive sleeve; for example, the retaining sleeve 400 can be made of metals such as copper or aluminum.

[0089] like Figure 3 , Figure 4 As shown, the heat-conducting component 300 includes a first surface 350 and a second surface 360, which are located on both sides of the thickness direction of the heat-conducting component 300.

[0090] In some possible implementations, the wire groove 310 is located on the first surface 350, and the pipe groove 320 is located on the second surface 360.

[0091] In this way, the wire grooves 310 and tube grooves 320 are respectively set on the two sides of the heat-conducting component 300 in the thickness direction. This makes it easier to set the wire grooves 310 and tube grooves 320 on the relatively small heat-conducting component 300. In other words, it helps to reduce the size of the heat-conducting component 300 with wire grooves 310 and tube grooves 320. In addition, the wire grooves 310 and tube grooves 320 are respectively located on the two sides of the heat-conducting component 300 in the thickness direction, so that the power wire 211 and the liquid cooling pipe 212 are respectively located on the two sides of the heat-conducting component 300 in the thickness direction. The fixing sleeve 400 applies pressure to the two sides of the heat-conducting component 300 in the thickness direction through the power wire 211 and the liquid cooling pipe 212, which helps to firmly press the power wire 211 and the liquid cooling pipe 212 onto the heat-conducting component 300. In addition, the power line 211 and the liquid cooling pipe 212 are located on opposite sides of the thickness direction of the heat-conducting component 300, making it less likely for the power line 211 and the liquid cooling pipe 212 to interfere with each other, and making the wiring easier.

[0092] For example, the first surface 350 and the second surface 360 ​​are parallel planes to facilitate the relatively secure pressing of the power line 211 and the liquid cooling pipe 212 onto the heat-conducting component 300.

[0093] In some examples where the inline groove 310 is located on the first surface 350, the conductive element 500 is located on one side of the first surface 350.

[0094] In some examples where the online groove 310 is located on the first surface 350 and the tube groove 320 is located on the second surface 360, the thickness of the heat conductor 300 is less than the width of the heat conductor 300.

[0095] In this way, the heat transfer path between the end of the power line 211 connected to the power supply component 21 and the liquid cooling pipe 212 is shorter, which is conducive to the liquid cooling pipe 212 dissipating heat more efficiently at the end of the power line 211 connected to the power supply component 21.

[0096] In some other possible implementations, the wire groove 310 and the pipe groove 320 may both be located on the first surface 350 or both on the second surface 360.

[0097] In some other possible implementations, one of the wire groove 310 and the tube groove 320 may be located on the surface of the heat conductor 300 in the thickness direction, and the other of the wire groove 310 and the tube groove 320 may be located on the surface of the heat conductor 300 in the width direction.

[0098] like Figure 3 , Figure 4 As shown, the heat-conducting component 300 also includes a first end face 330 and a second end face 340. The first end face 330 and the second end face 340 are located at opposite ends of the extension direction of the heat-conducting component 300. The first end face 330 is located at the end of the heat-conducting component 300 along the extension direction of the cable 200 that is closer to the gun head 100, and the second end face 340 is located at the end of the heat-conducting component 300 along the extension direction of the cable 200 that is farther away from the gun head 100.

[0099] For example, one end of the conductive element 500 is located between the first end face 330 and the second end face 340, and the other end of the conductive element 500 is located on the side of the second end face 340 away from the first end face 330. That is, the other end of the conductive element 500 protrudes from the second end face 340. The end of the conductive element 500 located on the side of the second end face 340 away from the first end face 330 is fixed to and electrically connected to the connecting copper busbar to realize the electrical connection between the conductive element 500 and the power supply component 21.

[0100] like Figure 3 As shown, in some possible implementations, one end of the groove 310 may extend through the first end face 330.

[0101] In this way, the power wire 211 can be easily inserted into the wire groove 310 from the first end face 330, making it easier to insert the power wire 211 into the wire groove 310 and facilitating the assembly of the power wire 211 with the heat-conducting component 300. Furthermore, it allows for a larger contact area between the power wire 211 and the heat-conducting component 300, resulting in a larger heat conduction area and facilitating more efficient heat dissipation from the power wire 211 by the liquid cooling pipe 212. Additionally, it also facilitates the wrapping and protection of the end of the power wire 211 connected to the power supply component 21 by the fixing sleeve 400.

[0102] For example, the other end of the groove 310 may extend through the second end face 340.

[0103] Thus, it is easier to form the linear groove 310 penetrating the first end surface 330 and the second end surface 340 on the surface of the heat-conducting member 300, which is beneficial to the processing of the heat-conducting member 300. In addition, the part of the power line 211 can extend out of the second end surface 340, and the assembly precision between the power line 211 and the heat-conducting member 300 is low, which is beneficial to the assembly between the power line 211 and the heat-conducting member 300.

[0104] In some possible embodiments, the end of the linear groove 310 close to the gun head 100 along the extension direction of the cable 200 can be a closed structure, that is, the end of the linear groove 310 close to the gun head 100 along the extension direction of the cable 200 is located between the first end surface 330 and the second end surface 340. At this time, the power line 211 can pass into the linear groove 310 from the first surface 350.

[0105] In some possible embodiments, the end of the linear groove 310 away from the gun head 100 along the extension direction of the cable 200 can be a closed structure, that is, the end of the linear groove 310 away from the gun head 100 along the extension direction of the cable 200 is located between the first end surface 330 and the second end surface 340.

[0106] As shown in Figure 3 , Figure 5 , Figure 3 , L1 is the slot width of the first slot section 311, and L2 is the slot width of the second slot section 312. In some possible embodiments, the linear groove 310 includes the first slot section 311 and the second slot section 312, one end of the first slot section 311 penetrates the end surface of the first end of the heat-conducting member 300, and the other end of the first slot section 311 is connected with the second slot section 312. The fixing sleeve 400 is crimped on the heat-conducting member 300, and the part of the conductive member 500 crimped on the heat-conducting member 300 is located at the second slot section 312, and the slot width L2 of the second slot section 312 is greater than the slot width L1 of the first slot section 311.

[0107] Thus, the slot width of the first slot section 311 for accommodating the power line 211 is narrow, which is beneficial to the part of the power line 211 protruding from the surface of the heat-conducting member 300 at the first slot section 311 to contact the fixing sleeve 400, and is beneficial to the fixing sleeve 400 crimping the power line 211 on the heat-conducting member 300 at the first slot section 311. The slot width of the second slot section 312 for accommodating the power line 211 is wide, which is convenient for the conductive member 500 to flatten the power line 211 at the second slot section 312, so that the conductive member 500 can be stably crimped on the heat-conducting member 300, which is beneficial to the stable assembly of the conductive member 500 and the heat-conducting member 300.

[0108] In some examples in which the linear groove 310 is located at the first surface 350, the conductive member 500 is crimped on the first surface 350.

[0109] AsFigure 3 As shown, the second slot section 312 penetrates the second end surface 340 from one end away from the first slot section 311, so as to form a wide-narrow linear slot 310 on the surface of the heat conduction member 300.

[0110] As shown, along the extension direction of the linear slot 310, from the one end of the first slot section 311 connected to the second slot section 312 to the one end of the second slot section 312 away from the first slot section 311, the slot cavity width of the second slot section 312 gradually increases, so as to facilitate the positioning of the power lines 211 in the gradually diverging state in the second slot section 312, and to make the slot wall of the second slot section 312 and the power lines 211 in the gradually diverging state in the second slot section 312 have a larger contact area.

[0111] As shown, in some possible embodiments, one end of the pipe slot 320 can penetrate the first end surface 330, and the other end of the pipe slot 320 can penetrate the second end surface 340. Figure 4 In this way, the liquid cooling pipe 212 can pass into the pipe slot 320 from the first end surface 330 and pass out of the pipe slot 320 from the second end surface 340, so that it is easier to pass the liquid cooling pipe 212 in the pipe slot 320 and easier to assemble the liquid cooling pipe 212 and the heat conduction member 300. In addition, it can also make the contact area between the liquid cooling pipe 212 and the heat conduction member 300 larger, so that the heat conduction area between the liquid cooling pipe 212 and the heat conduction member 300 is larger, which is beneficial to the more efficient heat dissipation of the liquid cooling pipe 212 to the power lines 211. In addition, it is also beneficial to the wrapping and protection of the liquid cooling pipe 212 by the fixing sleeve 400.

[0112] In other possible embodiments, at least one end of the pipe slot 320 can be a sealed structure. That is, at least one end of the pipe slot 320 is located between the first end surface 330 and the second end surface 340. The liquid cooling pipe 212 can pass into or out of the pipe slot 320 from the second surface 360.

[0113] As shown, in some possible embodiments, the surface of the heat conduction member 300 has a plurality of pipe slots 320, and the plurality of pipe slots 320 are arranged at intervals along the width direction of the heat conduction member 300.

[0114] Figure 4

[0115] ​​This arrangement facilitates the placement of multiple liquid cooling pipes 212 on the heat-conducting component 300. When multiple liquid cooling pipes 212 are arranged on the heat-conducting component 300, the heat-conducting component 300 can restrict the position of the multiple liquid cooling pipes 212 through the groove walls of the multiple pipe grooves 320, resulting in better stability and more reliable contact between the heat-conducting component 300 and the multiple liquid cooling pipes 212. Furthermore, when multiple liquid cooling pipes 212 are arranged on the heat-conducting component 300, the heat-conducting component 300 can contact the multiple liquid cooling pipes 212 through the groove walls of the multiple pipe grooves 320, resulting in a larger contact area between the heat-conducting component 300 and the multiple liquid cooling pipes 212. This larger heat conduction area facilitates more efficient heat dissipation of the power line 211 through the multiple liquid cooling pipes 212.

[0116] It should be noted that in the embodiments of this application, "more" means greater than or equal to "2". For example, "more items" means greater than or equal to "2 items".

[0117] Figure 6 As shown, for example, a liquid cooling pipe 212 is installed in each pipe groove 320.

[0118] like Figures 4-6 As shown, for example, the multiple grooves 320 on the surface of the heat-conducting component 300 include adjacent first grooves 320a and second grooves 320b. The cable 200 includes multiple liquid cooling pipes 212, including first liquid cooling pipes 212a and second liquid cooling pipes 212b. The first liquid cooling pipe 212a passes through the first groove 320a, and the second liquid cooling pipe 212b passes through the second groove 320b. The fixing sleeve 400 presses the first liquid cooling pipe 212a into the groove wall of the first groove 320a and the fixing sleeve 400 presses the second liquid cooling pipe 212b into the groove wall of the second groove 320b.

[0119] For example, one of the first liquid cooling pipe 212a and the second liquid cooling pipe 212b is a liquid inlet pipe, and the other of the first liquid cooling pipe 212a and the second liquid cooling pipe 212b is a liquid return pipe.

[0120] For example, the cable 200 includes multiple power cables 210, and the multiple power cables 210 of the cable 200 include a first power cable 210a and a second power cable 210b. The first power cable 210a and the second power cable 210b are both positive power cables or both are negative power cables. The first power cable 210a includes a first liquid cooling pipe 212a, and the second power cable 210b includes a second liquid cooling pipe 212b. The power lines 211 of the first power cable 210a and the power lines 211 of the second power cable 210b can be run in the same cable tray 310 and fixed to the same conductive element 500 and electrically connected.

[0121] Figure 8 A schematic view of a conductive member and a heat-conductive member cooperating with each other according to an embodiment of the present application is provided.

[0122] In some possible implementations, the heat-conductive member 300 has a dimension in the extension direction thereof that is greater than the width of the heat-conductive member 300.

[0123] In this way, the length of the portion of the heat-conductive member 300, the power line 211 and the liquid cooling pipe 212 that is covered by the fixing sleeve 400 can be longer, which facilitates the stable crimping of the power line 211 and the liquid cooling pipe 212 on the heat-conductive member 300.

[0124] Figure 9 A schematic view of a conductive member, a heat-conductive member and a cable cooperating with each other according to an embodiment of the present application is provided.

[0125] As shown in FIG. 1, the heat-conductive member 300 has a width direction and a length direction. Figure 8 、 Figure 9 In some examples in which the pipe groove 320 penetrates the first end face 330 at one end and the second end face 340 at the other end, the distance between the end of the first pipe groove 320a penetrating the first end face 330 and the end of the second pipe groove 320b penetrating the first end face 330 in the width direction of the heat-conductive member 300 is less than the distance between the end of the first pipe groove 320a penetrating the second end face 340 and the end of the second pipe groove 320b penetrating the second end face 340 in the width direction of the heat-conductive member 300.

[0126] In this way, the portion of the first liquid cooling pipe 212a located outside the second end face 340 and passing through the first pipe groove 320a is separated from the portion of the second liquid cooling pipe 212b located outside the second end face 340 and passing through the second pipe groove 320b, so as to form a mounting space for avoiding other components such as bolts, so that the liquid cooling pipe 212 is less likely to be damaged due to contact with the bolts and other components when the bolts and other components are mounted to the side of the second end face 340 away from the first end face 330.

[0127] For example, the conductive member 500 has a connecting hole 521, and the conductive member 500 is connected to the connecting copper bar through a fastener passing through the connecting hole 521. In the width direction of the heat-conductive member 300, the connecting hole 521 is located between the end of the first pipe groove 320a penetrating the second end face 340 and the end of the second pipe groove 320b penetrating the second end face 340.

[0128] In this way, the first liquid cooling pipe 212a and the second liquid cooling pipe 212b are spaced apart from the mounting space of the fastener connecting the conductive member 500 and the connecting copper bar on the side of the second end surface 340 away from the first end surface 330, so as to facilitate the avoidance of the fastener connecting the conductive member 500 and the connecting copper bar by the part of the first liquid cooling pipe 212a outside the second end surface 340 and the part of the second liquid cooling pipe 212b outside the second end surface 340, so as to facilitate the connection of the conductive member 500 and the connecting copper bar while preventing the first liquid cooling pipe 212a and the second liquid cooling pipe 212b from being damaged by the fastener connecting the conductive member 500 and the connecting copper bar.

[0129] For example, the conductive member 500 can be connected to the connecting copper bar by a threaded fastener passing through the connecting hole 521.

[0130] In some possible embodiments, the width of the heat conduction member 300 at the end where the first end surface 330 is located is smaller than the width of the heat conduction member 300 at the end where the second end surface 340 is located.

[0131] In this way, the width of the heat conduction member 300 close to the gun head 100 is small, which is beneficial to save installation space and facilitate the assembly of the heat conduction member 300, while facilitating the spacing between the end of the first pipe groove 320a penetrating the first end surface 330 and the end of the second pipe groove 320b penetrating the first end surface 330 in the width direction of the heat conduction member 300, which is smaller than the spacing between the end of the first pipe groove 320a penetrating the second end surface 340 and the end of the second pipe groove 320b penetrating the second end surface 340 in the width direction of the heat conduction member 300.

[0132] For example, the pipe groove 320 is a straight slot 310, so that the liquid cooling pipe 212 is easier to assemble in the pipe groove 320.

[0133] For example, the width of the heat conduction member 300 gradually increases from the first end surface 330 to the second end surface 340 in the extension direction of the heat conduction member 300.

[0134] In this way, the overall strength of the heat conduction member 300 is higher and is not prone to breakage.

[0136] For example, the conductive member 500 can be connected to the connecting copper bar by a threaded fastener passing through the connecting hole 521. Figures 10-12As shown, in some possible embodiments, the conductive member 500 includes a first portion 510 and a second portion 520 connected to each other. The first portion 510 is sleeved in the fixing sleeve 400, and the fixing sleeve 400 crimps the first portion 510 on at least one of the heat-conductive member 300 and the power line 211. The second portion 520 is located outside the fixing sleeve 400. The second portion 520 protrudes from a surface of the first portion 510 on a side away from the heat-conductive member 300, and a thickness of the part of the second portion 520 protruding from the surface of the first portion 510 on the side away from the heat-conductive member 300 is greater than or equal to a wall thickness of the fixing sleeve 400.

[0137] In this way, when the conductive member 500 is assembled with the connecting copper bar and the like, the second portion 520 protruding can be in contact with the connecting copper bar and the like, so that a space for accommodating the fixing sleeve 400 can be formed between the surface of the first portion 510 on the side away from the heat-conductive member 300 and the connecting copper bar and the like, so that the conductive member 500 is less likely to be lifted by the fixing sleeve 400 in contact with the connecting copper bar and the like, and stable assembly of the conductive member 500 with the connecting copper bar and the like is facilitated.

[0138] For example, the connecting hole 521 is located in the first portion 510.

[0139] For example, the side surface of the conductive member 500 close to the heat-conductive member 300 is a plane, that is, the side surface of the first portion 510 close to the heat-conductive member 300 and the side surface of the second portion 520 close to the heat-conductive member 300 are coplanar.

[0140] In this way, stable crimping of the conductive member 500 on the power line 211 and the heat-conductive member 300 is facilitated.
