Description

Technical Field

[0001] This application relates to the field of charging equipment technology, and in particular to a charging pipeline integrated box, a charging gun assembly and a charging device. Background Technology

[0002] Currently, new energy vehicles are typically equipped with large-capacity power batteries. To achieve rapid recharging, charging equipment such as charging piles needs to provide high output power to improve the user experience. High power usually means high current, which in turn means high heat generation. Therefore, active cooling technologies such as liquid cooling are sometimes required to improve charging efficiency.

[0003] However, the connection point between the charging gun's cable assembly and the charging pile body is the weakest point in the entire cooling system. Because the liquid cooling lines and cables of the charging gun and the charging pile body connect at this point, the risk of failure is relatively high. For example, when disassembling the charging gun's cable for maintenance, coolant spillage can easily cause contamination and short circuits in the wiring, thus affecting the equipment's operation.

[0004] In related technologies, a sealant is often placed around the joints of liquid cooling pipes or cables to isolate the coolant. However, liquid cooling pipes and cables cannot be completely sealed. During the plugging and unplugging of the charging gun cable, the liquid cooling pipes are still prone to leaking coolant, which can contaminate the cables and the copper busbars of the cables, causing a short circuit risk.

Detailed Implementation

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0050] According to a first aspect of this application, this application provides a charging cable integration box, please refer to... Figures 1-6 As shown, the charging cable integration box includes a box body 100 and a liquid cooling pipe connector 400. A cavity 101 is formed in the box body 100 for accommodating at least part of the cable 200 and the liquid cooling pipe 300. The liquid cooling pipe connector 400 is connected to the box body 100. One end of the liquid cooling pipe connector 400 is used to connect to the liquid cooling pipe 300, and the other end of the liquid cooling pipe connector 400 is located on the outside of the box body 100 away from the cavity 101.

[0051] Reference Figure 1 As shown, Figure 1This is a schematic diagram of the overall structure of the charging cable integration box. The charging cable integration box integrates a cable 200 and a liquid cooling pipe 300. When applied to the charging gun assembly, the cable 200 and the liquid cooling pipe 300 are the charging gun's cable 200 and liquid cooling pipe 300. The cable 200 and the liquid cooling pipe 300 can pass through the box body 100 and are at least partially housed in the cavity 101 formed by the box body 100, thereby realizing the collection and integration of the charging gun's tail cable. The cable 200 may include a power supply cable 201 and a signal cable 202. This part of the cable 200 is housed in the box body 100 and can be connected to the charging device through corresponding connectors, thereby realizing electrical connection and communication.

[0052] The liquid cooling pipe connector 400 is connected to the housing 100 for installation and fixation, and its two ends are used to connect pipelines to supply and receive liquid cooling pipes. Specifically, one end is connected to the liquid cooling pipe 300 of the charging gun 1400, and the other end is located on the outside of the housing 100 away from the cavity 101, such as... Figure 1 On the left side, the other end can be connected to the coolant supply and return lines of the charging equipment when it is installed. This allows the coolant to circulate and dissipate heat from the charging gun 1400 and the charging cable integration box. Since the cable 200 is located inside the cavity 101 of the box 100 and the other end of the liquid cooling pipe connector 400 is located outside the box 100, the two parts are separated. This also facilitates the installation, removal, and maintenance of the supply and return lines directly from the outside. When the supply and return lines of the charging equipment's reservoir are removed, even if coolant spills, it will not spill onto the cable 200, the electrical connectors connected to the cable 200, or the charging equipment due to the shielding of the box 100, thus avoiding contamination and preventing the risk of short circuits.

[0053] In some embodiments of this application, one end of the liquid cooling pipe connector 400 is used to connect to the liquid cooling pipe 300 inside the cavity 101, and the other end of the liquid cooling pipe connector 400 passes through the side wall 102 of the box 100 and is located on the outside of the box 100 away from the cavity 101.

[0054] Reference Figure 4 As shown, in this embodiment, the liquid cooling pipe connector 400 is inserted into the box 100, so that one end of the liquid cooling pipe 300 located inside the cavity 101 is connected, and the other end passes through the side wall 102 of the box 100 and is located on the outside of the box 100 away from the cavity 101, thereby achieving the separation of the other end from the cavity 101.

[0055] In other embodiments, both ends of the liquid cooling pipe connector 400 may be located outside the housing 100. For example, the housing 100 may have a through hole for the liquid cooling pipe 300 of the charging gun 1400 to pass through the through hole and connect to one end of the liquid cooling pipe connector 400. Similarly, the other end located outside is used to connect to the liquid supply line and the liquid return line of the liquid storage tank of the charging device.

[0056] It is understood that, to achieve coolant recirculation, multiple liquid cooling pipe connectors 400 can be configured. In this embodiment, there are two liquid cooling pipe connectors 400, connected side-by-side to the housing 100. One is used to connect to the supply pipe, and the other is used to connect to the return pipe. (Refer to...) Figure 6 As shown, this is the liquid flow path of the coolant in the liquid cooling pipe joint 400, quick-release joint 600 and liquid cooling pipe 300, where the arrows indicate the direction of coolant flow.

[0057] In some embodiments of this application, the cavity 101 is an open cavity, and the other end of the liquid cooling pipe connector 400 is located on opposite sides of the opening 111 of the open cavity, opposite to the side wall 102.

[0058] Reference Figure 1 and Figure 2 As shown, in this application, the housing 100 includes a bottom shell and side shells surrounding the bottom shell, which together form an open cavity. The opening 111 of the open cavity is the opening formed by the side shells. The other end of the liquid cooling pipe connector 400 is specifically located on opposite sides of the side wall 102 from the opening 111 of the open cavity. Specifically, refer to... Figure 1 The other end of the liquid cooling pipe connector 400 is located at Figure 1 The left side of the outer side of the middle box 100, and the opening 111 of the open cavity points to the right side, so that the supply and return lines of the charging equipment reservoir connected to the cable 200 integrated in the cavity 101 and the liquid cooling pipe connector 400 are arranged separately on both sides, avoiding structural pollution and short circuit problems caused by the coolant spilling out when the charging cable integrated box is disassembled.

[0059] In addition, the open cavity of the housing 100 facilitates the installation and removal of the cables 200 and the connected electrical connectors 1200 housed therein, and also facilitates heat dissipation of the internal structure. In some cases, such as when the housing 100 is connected to a charging device and communicates with the inside of the charging device, the cooling fan of the charging device can also turbulent the airflow inside the housing 100 to further improve the heat dissipation effect.

[0060] In some embodiments of this application, the housing 100 is provided with an outer edge 103 surrounding the opening 111 of the open cavity, and the outer edge 103 is provided with a mating mounting part 113.

[0061] Reference Figure 1 and Figure 2 As shown, the housing 100 has an outer edge 103, which has a mating mounting portion 113. Specifically, the mating mounting portion 113 can be a screw hole, a snap-fit ​​structure, etc., to facilitate mating and mounting with other structures. For example, see reference... Figure 7 As shown, the charging cable integration box is installed on the charging equipment housing 1300 by bolts.

[0062] In some embodiments of this application, the charging cable integration box further includes a first seal 500, which is disposed at the outer edge 103.

[0063] In some embodiments of this application, a groove 123 is formed at the outer edge 103, and the first seal 500 is disposed at the groove 123.

[0064] Reference Figure 1 and Figure 2 As shown, in this embodiment, by providing a first sealing element 500 at the outer edge 103, a better sealing effect can be achieved when installing the charging cable integration box, preventing dust or liquid from entering the box 100 and contaminating or short-circuiting the structural components therein.

[0065] Furthermore, in this embodiment, a groove 123 is provided at the outer edge 103. Specifically, it can be a long groove 123. The groove 123 is also arranged around the outer periphery of the opening 111 of the open cavity. The first sealing element 500 is provided in the groove 123, so that the installation of the first sealing element 500 is more stable.

[0066] In some embodiments of this application, the liquid cooling pipe connector 400 is sealed to the box body 100. For example, the joint position of the liquid cooling pipe connector 400 and the box body 100 is sealed by a sealing ring or the like, thereby strengthening the sealing inside and outside the box body 100, further preventing liquid from entering the box and contaminating the inside, causing a short circuit, and preventing dust from entering.

[0067] In some embodiments of this application, the liquid cooling pipe connector 400 includes a pagoda connector 401, which is located inside the cavity 101 and is used to connect to the liquid cooling pipe 300.

[0068] The 401 pagoda connector has one threaded part for connecting to pipes or equipment with internal threads, and the other part is pagoda-shaped with a bamboo-like structure for connecting hoses, gas pipes, oil pipes, etc. This allows the pipe to be fitted over the pagoda-shaped end and secured with wire or pipe clamps, facilitating a quick and secure connection. (See reference) Figure 4As shown, the connection between the pagoda connector 401 and the liquid cooling pipe 300 is more secure, more compatible, and has better sealing, preventing coolant from flowing out and contaminating the liquid and causing short circuits in the internal structural components of the housing 100.

[0069] In some embodiments of this application, the liquid cooling pipe connector 400 includes a plurality of pagoda connectors 401 for connection to the liquid cooling pipe 300. (See also...) Figure 4 As shown, in this embodiment, the liquid cooling pipe 300 is connected by multiple, such as two pagoda connectors 401. Thus, the liquid cooling pipe connector 400 can be regarded as a T-connector, thereby realizing the diversion of coolant. By diverting the flow, the water pressure can be reduced. When the coolant is flowing, the risk of coolant leakage at the connector can be reduced, further preventing pollution and short circuit.

[0070] In some embodiments of this application, the charging cable integration box further includes a quick-release connector 600, the other end of which is used to connect a liquid supply line or a liquid return line via the quick-release connector 600.

[0071] Reference Figures 1-7 As shown, in this embodiment, a quick-release connector 600 is provided, which connects to the other end of the liquid cooling pipe connector 400 located outside the housing 100, to achieve installation and fixation. The other end of the quick-release connector 600 can be conveniently and quickly connected to the liquid supply line or return line of the charging device. For example, two quick-release connectors 600 can be connected to the liquid supply line and the return line respectively, as shown in the example below. Figure 7 As shown, when installed in a charging device, the coolant lines of the charging device can be quickly disassembled, thereby facilitating maintenance.

[0072] The 600 quick-release connector can be a quick-connect fitting; during installation, the fluid tube is directly inserted into the connector, and the internal elastic retaining ring or locking mechanism automatically clamps the fluid tube, achieving quick connection and sealing. It can also be a clamp-type quick-connect connector, where the connection is achieved by the spring on the clamp gripping and engaging the inner edge of the fluid tube.

[0073] In some embodiments of this application, the quick-release connector 600 is rotatably connected to the liquid cooling pipe connector 400.

[0074] In this embodiment, the quick-release connector 600 is rotatably connected to the liquid cooling pipe connector 400, enabling 360° rotation without dead angles. This can meet the various wiring connection requirements of the liquid cooling pipe of the charging equipment and save installation space.

[0075] In some embodiments of this application, the quick-release connector 600 includes a first connector portion 601 and a second connector portion 602 connected to each other. The second connector portion 602 is connected to the other end of the liquid cooling pipe connector 400, and the first connector portion 601 and the second connector portion 602 are arranged at an angle.

[0076] Reference Figure 2 and Figure 4 As shown, in this embodiment, the first connector portion 601 and the second connector portion 602 are arranged vertically, with the included angle between the first connector portion 601 and the second connector portion 602 being 90°. The first connector portion 601 forms a 90° angle with the liquid cooling pipe connector 400, which facilitates meeting various wiring requirements of the liquid cooling pipeline. Combined with the aforementioned rotatable connection between the quick-release connector 600 and the liquid cooling pipe connector 400, wiring becomes even more convenient.

[0077] In some embodiments of this application, at least a portion of the outer wall of the housing 100 is recessed toward the interior of the housing 100 to form a stepped structure 104, and the liquid cooling pipe joint 400 is disposed at the stepped structure 104.

[0078] Reference Figure 4 and Figure 5 As shown, part of the outer wall of the box 100 is recessed inward to form the stepped structure 104. The side wall 102 through which the liquid cooling pipe connector 400 passes is part of the stepped structure 104. Thus, when the liquid cooling pipe connector 400 is located at the stepped structure 104, it can be flush with other outer wall surfaces of the box 100 or only partially protrude, without protruding too much structural part on the box 100, so that the liquid cooling pipe connector 400 can be protected to a certain extent. On the other hand, the overall structural size of the charging cable integrated box is smaller.

[0079] In some embodiments of this application, a conduit through hole 105 is provided at the box body 100, and the conduit through hole 105 communicates with the cavity 101.

[0080] Reference Figure 1 As shown, in this embodiment, when the charging cable integration box integrates the cable 200 and the liquid cooling pipe 300, a conduit through hole 105 is provided to allow the cable 200 and the liquid cooling pipe 300 to pass through simultaneously and be partially accommodated in the cavity 101, thereby making the overall integration of the charging cable integration box higher.

[0081] In other embodiments, multiple wire holes may be provided at the housing 100 to allow different cables and liquid cooling pipes 300 to pass through respectively.

[0082] In some embodiments of this application, the charging cable integration box further includes a second seal 700, which is disposed at the cable through hole 105.

[0083] Reference Figures 1-3As shown in the embodiment of this application, by setting a second sealing element 700, the connection between the cable 200 and the liquid cooling pipe 300 and the box 100 is sealed, thereby improving the overall sealing effect of the charging pipeline integrated box and preventing external dust or liquid from flowing into the box 100 and causing pollution and short circuit.

[0084] In some embodiments of this application, the second seal 700 includes a sealing sleeve 700a, through which the cable 200 and / or the liquid cooling pipe passes. The outer side of the sealing sleeve 700a is used to seal the conduit through hole 105, and the inner side of the sealing sleeve 700a is used to seal the cable 200 and / or the liquid cooling pipe 300.

[0085] Reference Figures 1-3 As shown, in this embodiment, the second sealing element 700 can specifically be a sealing sleeve 700a made of rubber material. The sealing sleeve 700a is embedded in the conduit through hole 105. When the wire harness composed of the cable 200 and the liquid cooling pipe 300 is installed, it passes through the sealing sleeve 700a and the conduit through hole 105 to enter the cavity 101. In this way, the sealing sleeve 700a not only achieves sealing, but also protects the wire sheath at the outlet and the internal wiring, which facilitates the installation of internal components and subsequent maintenance and replacement.

[0086] In some embodiments of this application, the charging pipeline integration box also includes a limiting structure 800, which is disposed within the cavity 101.

[0087] Reference Figure 3 As shown in the embodiment of this application, by setting a limiting structure 800 in the cavity 101, the cable 200 and the liquid cooling pipe 300 can be limited and fixed by the limiting structure 800 when integrating the cable 200 and the liquid cooling pipe 300, so that the integration is more compact and prevents shaking during use.

[0088] In some embodiments of this application, the limiting structure 800 includes a wire clamp 800a, which is located inside the cavity 101 near the end of the conduit through hole 105.

[0089] Reference Figure 3 As shown in the embodiment of this application, the limiting structure 800 is specifically in the form of a wire clamp 800a, and is specifically located in the cavity 101 near the end of the wire conduit through hole 105, so as to clamp the cable 200 and liquid cooling pipe 300 entering the cavity 101 and prevent them from shaking.

[0090] The cable clamp 800a can be connected and fixed to the housing 100 by bolts or the like, or it can cooperate with the housing 100 to form a clamping opening to fix the position of the cable 200 and liquid cooling pipe 300 passing through it. Specifically, the cable 200 and / or liquid cooling pipe 300 are arranged between the cable clamp 800a and the housing 100, and the opposing surfaces of the cable clamp 800a and the housing 100 are used to clamp the cable 200 and / or liquid cooling pipe 300.

[0091] In some embodiments of this application, the charging cable integration box further includes a separator 900, which is disposed within the cavity 101 and forms at least two separate cable passages 901.

[0092] Reference Figure 2 and Figure 3 As shown, a separator 900 is provided in the cavity 101 to achieve the separation and arrangement of the cables 200. Specifically, the separator 900 forms two separate cable passages 901. When installing the cables 200, some cables 200 that need to be separated, such as some power cables 201 that have cables connecting positive and negative poles, are separated and arranged by setting the separator 900. This achieves the classification of the lines and can prevent the power cables 201 and the electrical connectors 1200 connected to the power cables 201 from contacting and short-circuiting.

[0093] In some embodiments of this application, the charging cable integration box further includes a clamp 1000, the liquid cooling pipe connector 400 is used to insert the liquid cooling pipe 300, the clamp 1000 is used to fit around the outer periphery of the liquid cooling pipe 300, and cooperates with the liquid cooling pipe connector 400 to clamp the liquid cooling pipe 300.

[0094] Reference Figure 1 and Figure 4 As shown, in this embodiment, by setting a clamp 1000, when installing the liquid cooling pipe 300, the clamp 1000 is sleeved on the outer periphery of the liquid cooling pipe 300, and the liquid cooling pipe connector 400 is inserted into the liquid cooling pipe 300 so as to cooperate in clamping the liquid cooling pipe connector 400. Specifically, it cooperates with the pagoda connector 401 of the liquid cooling pipe connector 400 to clamp the liquid cooling pipe 300 and prevent leakage.

[0095] In some embodiments of this application, the charging cable integration box further includes a cover plate 1100, which is connected to the box body 100. The opposing surfaces of the cover plate 1100 and the box body 100 are used to clamp the liquid cooling pipe connector 400.

[0096] Reference Figures 1-3As shown, in this embodiment, a cover plate 1100 is provided to cooperate with the housing 100 to clamp and fix the liquid cooling pipe connector 400, thereby achieving stable installation of the liquid cooling pipe connector 400. Specifically, the cover plate 1100 can be located inside the cavity 101, and it has screw holes for connection with the housing 100 by bolts. One end of the liquid cooling pipe connector 400 is located between the cover plate 1100 and the housing 100, thereby the cover plate 1100 cooperates with the housing 100 to press the liquid cooling pipe connector 400.

[0097] According to a second aspect of this application, a charging gun assembly is provided, including a charging cable integration box as described above, a charging gun 1400, and a cable 200 and a liquid cooling pipe 300 connected to the charging gun 1400.

[0098] The charging gun assembly of this application embodiment has the same or similar technical effects as the charging pipeline integrated box described above, and will not be described again here.

[0099] In some embodiments of this application, the liquid cooling pipe 300 passes through the housing 100 of the charging cable integrated box and communicates with the liquid cooling pipe connector 400 of the charging cable integrated box.

[0100] In this embodiment, the charging gun assembly includes a liquid cooling pipe 300, which enables heat exchange and cooling of the charging part of the charging gun, the charging pipeline integration box, and other related parts when the coolant is circulating. Specifically, the liquid cooling pipe 300 passes through the box 100 to integrate the charging gun's liquid cooling pipe 300 at the connection point with the charging device, and connects to the liquid cooling pipe connector 400 of the charging pipeline integration box to achieve pipeline connectivity. It can be understood that the other end of the liquid cooling pipe connector 400, located outside the box 100, is used to connect to the liquid supply and return pipelines of the charging device, realizing coolant circulation between the charging device and the charging gun assembly.

[0101] In some embodiments of this application, the cable 200 includes at least one of a power supply cable 201 and a signal cable 202.

[0102] In this embodiment, the cable 200 of the charging gun assembly may include a power supply cable 201 and a signal cable 202, so as to realize power supply and signal transmission to the charging gun when connected to the charging device.

[0103] In some embodiments of this application, the cable 200 passes through the housing 100 of the charging cable integration box and extends out from the opening 111 of the open cavity of the charging cable integration box.

[0104] In this embodiment, the cable 200 specifically passes through the box 100 to achieve line integration of the charging gun cable 200 at the connection point with the charging device. The cable 200 also passes through the opening 111 of the open cavity, thus partially exposing itself outside the box 100, which facilitates the installation personnel to operate the cable 200 and cooperate with other structures of the charging device for installation.

[0105] In some embodiments of this application, the charging gun assembly further includes an electrical connector 1200, and the power supply cable 201 includes at least two power supply cables 201, which are electrically connected to the electrical connector 1200.

[0106] Reference Figure 1 As shown, in this embodiment, the two power supply cables 201 specifically include a positive power line 201a and a negative power line 201b. The electrical connector 1200 is specifically a copper busbar. After the cable 200 is split at the end, it is connected to the corresponding copper busbar. The connection method can be ultrasonic welding. The copper busbar can be provided with screw holes and connected and fixed to the power module in the charging device by bolt connection to realize circuit conduction.

[0107] In some embodiments of this application, the charging gun assembly further includes a separator 900. The power supply cable 201 includes a positive power line 201a and a negative power line 201b. The separator 900 is disposed within the cavity 101 and forms at least two separate wire passages 901. The positive power line 201a and the negative power line 201b pass through the two separate wire passages 901 respectively.

[0108] Reference Figure 2 and Figure 3 As shown, the separator 900 of the charging cable integration box forms two separate wire passages 901. The positive power line 201a and the negative power line 201b are respectively passed through the two wire passages 901, which can prevent the power lines and the copper busbars connected to the power lines from contacting each other and short-circuiting.

[0109] In some embodiments of this application, the charging gun assembly further includes a second seal 700, which is disposed at the conduit through-hole 105 of the charging cable integration box.

[0110] Reference Figures 1-3 As shown in the embodiment of this application, the charging gun assembly seals the connection between the cable 200 and the liquid cooling pipe 300 and the box 100 by setting a second sealing element 700, thereby improving the overall sealing effect of the charging pipeline integrated box and preventing external dust or liquid from flowing into the box 100 and causing pollution and short circuit.

[0111] In some embodiments of this application, the second seal 700 includes a sealing sleeve 700a through which the cable 200 and / or the liquid cooling pipe passes. The outer side of the sealing sleeve 700a is used to seal the conduit through hole 105, and the inner side of the sealing sleeve 700a is used to seal the cable 200 and / or the liquid cooling pipe 300.

[0112] Reference Figures 1-3 As shown, in this embodiment, the second sealing element 700 can specifically be a sealing sleeve 700a made of rubber material. The sealing sleeve 700a is embedded in the conduit through hole 105. When the cable 200 and liquid cooling pipe 300 of the charging pile component are installed, the wire harness passes through the sealing sleeve 700a and the conduit through hole 105 and enters the cavity 101. In this way, the sealing sleeve 700a not only achieves sealing, but also protects the cable sheath at the outlet and the internal wiring, which facilitates the installation of internal components and subsequent maintenance and replacement.

[0113] In some embodiments of this application, the charging gun assembly further includes a limiting structure 800, which is disposed within the cavity 101 of the charging pipeline integration box.

[0114] Reference Figure 3 As shown in the embodiment of this application, the charging pile assembly provides a limiting structure 800 in the cavity 101 of the charging pipeline integration box. In this way, when integrating the cable 200 and the liquid cooling pipe 300, the limiting structure 800 can limit and fix the cable 200 and the liquid cooling pipe 300, thereby making the integration more compact and preventing shaking during use.

[0115] In some embodiments of this application, the limiting structure 800 includes a wire clamp 800a, which is located inside the cavity 101 near the end of the conduit through hole 105.

[0116] Reference Figure 3 As shown in the embodiment of this application, the limiting structure 800 is specifically in the form of a wire clamp 800a, and is specifically located in the cavity 101 near the end of the wire conduit through hole 105, so as to clamp the cable 200 and liquid cooling pipe 300 entering the cavity 101 and prevent them from shaking.

[0117] In some embodiments of this application, the cable 200 and / or the liquid cooling pipe 300 are disposed between the cable clamp 800a and the housing 100 of the charging cable integration box, and the opposing surfaces of the cable clamp 800a and the housing 100 are used to clamp the cable 200 and / or the liquid cooling pipe 300.

[0118] Reference Figure 3As shown in the embodiment of this application, the cable clamp 800a can be a strip structure. The cable clamp 800a can be connected and fixed to the box body 100 by bolts or the like, and cooperate with the box body 100 to form a clamping opening to clamp the cable 200 and liquid cooling pipe 300 passing through it, thereby fastening them.

[0119] In other embodiments, the wire clamp 800a can also clamp the cable 200 and the liquid cooling tube 300 separately, such as by using a wire harness structure that can be scaled up or down for clamping and securing the wires.

[0120] According to a third aspect of this application, a charging device is proposed, including a charging pipeline integration box as described above or a charging gun assembly as described above.

[0121] The charging devices in this application embodiment, such as charging piles, have the same or similar technical effects as the charging pipeline integration box and charging gun assembly described above, and will not be described in detail here.

[0122] In some embodiments of this application, the charging device further includes a housing 1300 and a fan disposed inside the housing 1300, the interior of the housing 1300 being connected to the cavity 101 of the charging pipeline integration box.

[0123] Reference Figure 7 As shown, in this embodiment, the cavity 101 of the charging cable integration box is an open cavity. When the charging cable integration box is installed, it is connected to the inside of the box 1300 through the opening 111 of the open cavity. When the fan dissipates heat inside the box 1300, the air circulation can better dissipate heat from the charging cable integration box. By further dissipating heat from this heat dissipation blind area, heat accumulation is further reduced, and its current carrying capacity is improved.
