Description

Technical Field

[0001] This application relates to the field of charging pile technology, and in particular to a charging gun, a heat dissipation component, and a charging pile. Background Technology

[0002] In related technologies, ultra-high power non-immersion liquid-cooled DC charging guns use coolant pipes to dissipate heat from the wires. However, since the wires inside the charging gun need to be connected to the power cable or conductor bar of the charging pile, and the coolant pipes need to be connected to the liquid cooling heat dissipation pipes of the charging pile, the coolant pipes and wires will separate at the tail end of the charging gun. In other words, the coolant pipes cannot provide good heat dissipation for the wires at the tail end of the charging gun.

[0003] Therefore, during the use of the charging gun, the wires located at the tail of the charging gun cannot effectively dissipate heat, thus limiting the increase of the charging current of the charging gun. Utility Model Content

[0077] 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.

[0078] This application proposes a charging gun. Figures 1 to 12 These are some embodiments of this application.

[0079] Please see Figures 1 to 3In some embodiments of this application, the charging gun 1000 includes at least one charging cable harness 10 and a heat dissipation structure 200. The end of the charging cable harness 10 is configured to be connected to the connection terminal 1. The heat dissipation structure 200 is thermally connected to the charging cable harness 10 and is configured to dissipate heat from the end of the charging cable harness 10.

[0080] In the technical solution of this application, the end of the charging harness 10 is a wire located at the tail of the charging gun 1000 in the related technology. By providing a heat dissipation structure 200 on one side of the end of the charging harness 10, the end of the charging harness 10 located at the tail of the charging gun 1000 can be effectively cooled during the use of the charging gun 1000, so that the charging current of the charging gun 1000 can be increased.

[0081] It is understood that, since the charging current of the charging gun 1000 in this application embodiment can be increased, the charging rate of the vehicle when using the charging gun 1000 in this application embodiment for charging can also be effectively improved.

[0082] In addition, the end of the charging harness 10 is connected to the connection terminal 1, and then connected to the power cable through the connection terminal 1.

[0083] In some embodiments of this application, the connection terminal 1 is the terminal portion that is inserted into the charging port of the vehicle; since the end of the charging harness 10 is separated from the coolant pipe in the related art when the charging harness 10 is connected to the connection terminal 1, that is, the end of the charging harness 10 in the above embodiments is separated from the coolant pipe, the heat dissipation structure 200 can dissipate heat from the end of the charging harness 10, thereby reducing the heat generation at the end of the charging harness 10.

[0084] In some embodiments of this application, the charging gun 1000 includes a housing 2 and a charging cable 100 located inside the housing 2. The charging cable 100 has a plurality of charging wire harnesses 10, which are connected to a power cable.

[0085] There is no limit to the number of charging cable bundles 10 that can be installed. However, adjacent charging cable bundles 10 are insulated from each other to avoid short circuits.

[0086] Similarly, the method of insulating two or more adjacent charging harnesses 10 from each other is not limited; in one embodiment, an insulating layer may be wound around the outer periphery of the charging harness 10; in another embodiment, a heat-shrinkable sleeve may be provided around the outer periphery of the charging harness 10.

[0087] In some embodiments of this application, the charging harness 10 is formed by combining multiple harnesses.

[0088] It should be noted that the multiple charging harnesses 10 include a positive wire connected to the power source and a negative wire connected to the power source.

[0089] In some embodiments of this application, the charging cable 100 includes a protective sleeve 13, and a plurality of charging cable bundles 10 are located inside the protective sleeve 13, which can provide protection for the plurality of charging cables 100.

[0090] In some embodiments of this application, the charging cable 100 also includes a plurality of small wire harnesses 11 located within the protective sleeve 13; wherein, the small wire harnesses 11 are used to connect various electronic components inside the charging gun 1000, such as control circuits, sensors, etc., to be responsible for transmitting control signals and power, and to ensure that the charging gun 1000 can work normally.

[0091] In some embodiments of this application, the charging cable 100 further includes a filler 12 located within the protective sleeve 13 and around the charging cable 100 and the small wire harness 11. The filler 12 serves to fix and protect the charging wire harness 10 and the small wire harness 11, preventing damage to them due to excessive pulling during use, and also improving the overall structural strength and durability of the charging gun 1000. Furthermore, the filler 12 may also have certain insulating properties to prevent the risk of electrical short circuits or leakage within the charging gun 1000.

[0092] In some embodiments of this application, the charging harness 10 includes a first segment 10A, which is the end of the charging harness 10; the heat dissipation structure 200 includes at least one parallel conductor 20, which is connected in parallel with at least a portion of the first segment 10A; wherein, with the total current of the charging cable 100 remaining constant, the parallel conductor 20 connected in parallel to the first segment 10A reduces the current passing through the first segment 10A. According to Joule's law, the heat generated by current passing through a conductor is proportional to the square of the current. Therefore, the reduction in the current passing through the first segment 10A reduces the heat generated by the current passing through the first segment 10A, thereby lowering the temperature of the first segment 10A and achieving good heat dissipation.

[0093] In some embodiments of this application, the parallel conductor 20 contacts the first segment 10A along its length; that is, in this embodiment, the entire parallel conductor 20 is in contact with the first segment 10A, and the cross-sectional area of ​​the bundle formed by the parallel conductor 20 and the first segment 10A is larger than the cross-sectional area of ​​the first segment 10A, thereby reducing the resistance of the part of the parallel conductor 20 in contact with the first segment 10A, thereby reducing the heat generated when current flows through the first segment 10A.

[0094] The parallel connection method between the parallel conductor 20 and the first segment 10A is not limited; it can be welding or connected through other components.

[0095] In some embodiments of this application, the two ends of the parallel conductor 20 are welded to the first sub-segment 10A so that the parallel conductor 20 is connected in parallel with the first sub-segment 10A.

[0096] Please see Figure 1 , Figure 4 and Figure 5 In some embodiments of this application, the heat dissipation structure 200 further includes at least one connector 21, and at least one end of the parallel wire 20 and the first segment 10A are connected through the connector 21; that is, in this embodiment, by providing the connector 21, the parallel wire 20 and the first segment 10A are connected in parallel, thereby reducing the temperature of the first segment 10A.

[0097] The type of connector 21 is not limited; in one embodiment, connector 21 is a crimp terminal; in another embodiment, connector 21 is a plug.

[0098] Since the parallel conductor 20 includes two ends, the connection method between the two ends of the parallel conductor 20 and the first segment 10A can be the same or different.

[0099] Please see Figure 1 In some embodiments of this application, both ends of the parallel conductor 20 are connected to the first sub-segment 10A via connector 21.

[0100] Please see Figure 4 and Figure 5 In some embodiments of this application, one end of the parallel wire 20 is connected to the first sub-segment 10A by a connector 21, and the other end of the parallel wire 20 is connected to the first sub-segment 10A.

[0101] Please refer to it again. Figure 4 and Figure 5 In some embodiments of this application, one end of the parallel wire 20 is connected to the first sub-segment 10A by a connector 21, and the other end of the parallel wire 20 is connected to one end of the first sub-segment 10A. This configuration allows the end of the parallel wire 20 to be connected to the end of the first sub-segment 10A, thereby increasing the parallel length between the first sub-segment 10A and the parallel wire 20, and thus preventing the local temperature of the first sub-segment 10A from becoming too high.

[0102] It is understandable that if only part of the first segment 10A is connected in parallel with the parallel wire 20, the temperature of the part of the first segment 10A connected in parallel with the parallel wire 20 will decrease, while the temperature of the part of the first segment 10A not connected in parallel with the parallel wire 20 will not decrease, which will limit the increase of the charging current of the charging gun 1000.

[0103] Please see Figure 4 In some embodiments of this application, one end of the parallel wire 20 is welded to one end of the first sub-segment 10A, and the other end of the parallel wire 20 is connected to the first sub-segment 10A through the connector 21, so as to realize the parallel connection of the parallel wire 20 and the first sub-segment 10A.

[0104] In some embodiments of this application, one end of the parallel conductor 20 is connected to one end of the first segment 10A by ultrasonic welding; of course, the welding method of the parallel conductor 20 and the first segment 10A is not limited to the above embodiments, and any welding method applied to cables is suitable for welding the parallel conductor 20 and the first segment 10A in this application.

[0105] Please see Figure 5 In some embodiments of this application, the parallel wire 20 and the first sub-segment 10A are integrally formed; this configuration means that when the parallel wire 20 and the first sub-segment 10A are connected in parallel, only one end of the parallel wire 20 needs to be connected to the first sub-segment 10A, which is simple, convenient and highly reliable in manufacturing.

[0106] In some embodiments of this application, the parallel conductor 20 is formed by bending at least a portion of the charging harness 10; in this embodiment, the charging harness 10 is bent to form the interconnected parallel conductor 20 and the first sub-segment 10A; wherein, the end of the parallel conductor 20 away from the first sub-segment 10A is connected or welded to the first sub-segment 10A by a connector 21, and the bent portion of the charging harness 10 is welded to the connection terminal 1 to realize the parallel connection of the first sub-segment 10A and the parallel conductor 20.

[0107] It should be noted that the parallel wire 20 is formed by bending the charging cable harness 10, which is simple, convenient and reliable. Since one end of the parallel wire 20 does not need to be welded to one end of the first segment 10A or connected by the connector 21, the internal space of the charging gun 1000 can be saved. In addition, this setting can also improve the manufacturing efficiency of the charging gun 1000.

[0108] In some embodiments of this application, one end of the parallel wire 20 is connected to the first sub-segment 10A via a connector 21, and the other end of the parallel wire 20 is connected to the connecting terminal 1; that is, in this embodiment, the parallel connection between the parallel wire 20 and the first sub-segment 1 is achieved by connecting the parallel wire 20 to the connecting terminal 1.

[0109] In some embodiments of this application, the charging harness 10 includes a first segment 10A, which is the end of the charging harness 10; the heat dissipation structure 200 includes a parallel conductor 20, which extends along the extension direction of the first segment 10A and at least a portion of the parallel conductor 20 is connected to the first segment 10A; that is, in this embodiment, the cross-sectional area of ​​the harness formed by the connection of the parallel conductor 20 and the first segment 10A is increased, thereby reducing the resistance of the portion where the parallel conductor 20 is connected to the first segment 10A, thereby reducing the heat generated when current flows through the first segment 10A.

[0110] In some embodiments of this application, the entire parallel conductor 20 is connected to the first segment 10A; this arrangement increases the portion of the first segment 10A connected to the parallel conductor 20, thereby effectively reducing the heat generated when current flows through the first segment 10A.

[0111] In some embodiments of this application, a portion of the parallel conductor 20 is connected to the first sub-segment 10A, and another portion is connected in parallel with the first sub-segment 10A, which can also effectively reduce the heat generated when current flows through the first sub-segment 10A.

[0112] In some embodiments of this application, the charging harness 10 includes a first sub-segment 10A and a second sub-segment 10B connected to each other. The first sub-segment 10A is the end of the charging harness 10, and the second sub-segment 10B is used to contact the cooling pipe 22. The cross-sectional area of ​​the first sub-segment 10A is larger than the cross-sectional area of ​​the second sub-segment 10B, that is, the resistance of the first sub-segment 10A is smaller than the resistance of the second sub-segment 10B, so as to reduce the heat generated when current is passed through the first sub-segment 10A.

[0113] In some embodiments of this application, both the first sub-segment 10A and the second sub-segment 10B are composed of multiple wire harnesses, and the number of wire harnesses constituting the first sub-segment 10A and the second sub-segment 10B is the same. Therefore, the thickness of some wire harnesses forming the first sub-segment 10A is greater than the thickness of some wire harnesses forming the second sub-segment 10B, thereby making the cross-sectional area of ​​the first sub-segment 10A larger than the cross-sectional area of ​​the second sub-segment 10B, so as to reduce the heat generated when current is passed through the first sub-segment 10A.

[0114] Since the second segment 10B can dissipate heat through the cooling pipe 22, there is no need to set the second segment 10B to have a large cross-sectional area, so as to save costs.

[0115] Please see Figures 1 to 3In some embodiments of this application, the charging harness 10 includes a first sub-segment 10A and a second sub-segment 10B connected to each other. The first sub-segment 10A is the end of the charging harness 10. The heat dissipation structure 200 also includes a cooling pipe 22, which is in contact with the second sub-segment 10B to dissipate heat from the second sub-segment 10B. The cooling pipe 22 is separate from the first sub-segment 10A. That is, in this embodiment, the cooling pipe 22 is used to dissipate heat from the second sub-segment 10B to avoid the second sub-segment 10B from getting too hot during use, thereby limiting the increase of the charging current of the charging gun 1000.

[0116] Since the cooling pipe 22 needs to be connected to the liquid cooling heat dissipation pipe of the charging pile 10000, and the charging harness 10 needs to be connected to the power cable of the charging pile 10000, the cooling pipe 22 and the charging harness 10 are partially separated, that is, the cooling pipe 22 is separated from the first sub-segment 10A.

[0117] It is understandable that by providing cooling pipes 22 and parallel wires 20, the second sub-segment 10B and the first sub-segment 10A of the charging harness 10 are cooled respectively, so that the charging current of the charging gun 1000 can be increased.

[0118] In some embodiments of this application, the wall material of the cooling pipe 22 is an insulating material, and the cooling liquid flows through the cooling pipe 22 to carry away the heat generated by the charging harness 10 when the vehicle is charging at high power.

[0119] Please see Figures 2 to 3 In some embodiments of this application, the number of cooling pipes 22 is set to four, wherein two of the four cooling pipes 22 are used to introduce coolant and the other two are used to discharge coolant.

[0120] It should be noted that there is no limit to the number of cooling pipes 22; in one embodiment of this application, there are two cooling pipes 22, one of which is used to introduce coolant and the other is used to discharge coolant.

[0121] In another embodiment of this application, three cooling pipes 22 are provided. Alternatively, one of the three cooling pipes 22 may be used to introduce coolant, and the other two may be used to discharge coolant; or two of the three cooling pipes 22 may be used to introduce coolant, and the other may be used to discharge coolant.

[0122] Please see Figure 2 In some embodiments of this application, the cooling pipe 22 is coaxially arranged with the charging harness 10, that is, the cooling pipe 22 is located inside the second sub-segment 10B to dissipate heat from the second sub-segment 10B.

[0123] Please see Figure 3In some embodiments of this application, the cooling pipe 22 is located on one side of the second sub-segment 10B, thereby dissipating heat from the second sub-segment 10B.

[0124] Please see Figure 6 This application also proposes a heat dissipation component 300 for dissipating heat from the charging gun 1000. The heat dissipation component 300 includes a mounting part 30 and a heat dissipation part 31. The mounting part 30 is used to mount the end of the charging cable harness 10, and the heat dissipation part 31 is used to dissipate heat from the end of the charging cable harness. That is, in this embodiment, by assembling the end of the charging cable harness 10 with the heat dissipation component 300, the heat dissipation part 31 can dissipate heat from the end of the charging cable harness during the use of the charging gun 1000.

[0125] The positional relationship between the heat dissipation part 31 and the mounting part 30 is not restricted.

[0126] In one embodiment, the heat dissipation part 31 and the mounting part 30 are connected to and in contact with each other, such as the heat dissipation part 31 and the mounting part 30 being integrally provided or separately assembled.

[0127] In another embodiment, the heat dissipation part 31 and the mounting part 30 do not contact each other.

[0128] In some embodiments of this application, the mounting part 30 dissipates heat from the first sub-segment 10A.

[0129] In some embodiments of this application, the heat dissipation assembly 300 further includes a limiting part 32, which is fixedly connected to the mounting part 30 to restrict the end of the charging cable harness 10 from separating from the mounting part 30. That is, in this embodiment, the mounting part 30 and the end of the charging cable harness 10 can be fixed relative to each other by the cooperation of the limiting part 32 and the mounting part 30, thereby preventing the heat dissipation assembly 300 from separating from the charging cable harness 10 during the use of the charging gun 1000, while the heat dissipation part 31 dissipates heat from the end of the charging cable harness 10.

[0130] In some embodiments of this application, a heat dissipation part 31 is provided on at least one of the mounting part 30 and the limiting part 32, so as to dissipate heat at the end of the charging cable harness 10 when the heat dissipation assembly 300 is assembled with the charging cable harness 10.

[0131] In one embodiment, a heat dissipation part 31 is provided on the mounting part 30 so as to dissipate heat at the end of the charging cable harness 10 when the heat dissipation assembly 300 is assembled with the charging cable harness 10.

[0132] In another embodiment, a heat dissipation part 31 is provided on the limiting part 32, so as to dissipate heat at the end of the charging cable harness 10 when the heat dissipation assembly 300 is assembled with the charging cable harness 10.

[0133] In another embodiment, the heat dissipation part 31 is provided on both the mounting part 30 and the limiting part 32, so as to dissipate heat at the end of the charging cable harness 10 when the heat dissipation assembly 300 is assembled with the charging cable harness 10.

[0134] Please see Figure 7 In some embodiments of this application, the heat dissipation part 31 is disposed on the mounting part 30 and is integrally disposed with the mounting part 30.

[0135] Please see Figure 8 In some embodiments of this application, the heat dissipation part 31 is provided on both the mounting part 30 and the limiting part 32, and the heat dissipation part 31 located on the mounting part 30 and the limiting part 32 are integrally formed with the mounting part 30 and the limiting part 32, respectively.

[0136] It is understandable that the heat dissipation part 31 and the mounting part 30 can be integrated into one piece, or the materials used to form the heat dissipation part 31 and the mounting part 30 can be mixed together so that the overall structure formed by the heat dissipation part 31 and the mounting part 30 has a heat dissipation function.

[0137] The heat dissipation part 31 and the limiting part 32 can also be integrated by mixing the materials used to form the heat dissipation part 31 and the limiting part 32, so that the overall structure formed by the heat dissipation part 31 and the limiting part 32 has a heat dissipation function.

[0138] It should be noted that the heat dissipation part 31 is made of thermally conductive material, that is, the heat generated at the end of the charging harness 10 can be dissipated through the heat dissipation part 31, and the thermally conductive material itself also has a heat storage function, which can resist the thermal shock of the vehicle when charging with ultra-high power and ultra-high current.

[0139] Furthermore, the heat dissipation component 300 can be installed and removed from the charging pile 10000 by means of the connection between the mounting part 30 and the limiting part 32, so that it can be designed according to the actual needs of the user.

[0140] The connection between the mounting part 30 and the limiting part 32 is not limited; it can be a bolt connection, a snap-fit ​​connection, or a structural adhesive bonding, etc.

[0141] In some embodiments of this application, thermally conductive silicone oil is provided between the first segment 10A and at least one of the limiting part 32 and the mounting part 30, thereby reducing the contact thermal resistance between the first segment 10A and at least one of the limiting part 32 and the mounting part 30.

[0142] Please see Figure 7 and Figure 8In some embodiments of this application, at least two ends of the charging harness 10 are insulated on the mounting portion 30; in this embodiment, at least a portion of the mounting portion 30 is located between the ends of two adjacent charging harnesses 10 to insulate the ends of the two adjacent charging harnesses 10; that is, the structure of the mounting portion 30 can prevent the ends of two adjacent charging harnesses 10 from contacting and short-circuiting.

[0143] Please see Figure 7 In some embodiments of this application, the combined structure of the mounting part 30 and the heat dissipation part 31 is made of a high thermal conductivity insulating material, thereby simultaneously possessing heat dissipation and insulation functions.

[0144] In some embodiments of this application, the combined structure of the mounting part 30 and the heat dissipation part 31 is made of ceramic.

[0145] In some embodiments of this application, the limiting part 32 is an insulating element, thereby playing an insulating role.

[0146] The limiting part 32 and the mounting part 30 are arranged around the periphery of the end of the charging cable harness 10 to further prevent the ends of two adjacent charging cable harnesses 10 from contacting and short-circuiting.

[0147] In some embodiments of this application, the combined structure of the limiting part 32 and the heat dissipation part 31 is made of a high thermal conductivity insulating material, thereby simultaneously possessing heat dissipation and insulation functions.

[0150] In some embodiments of this application, one of the mounting portion 30 and the limiting portion 32 is provided with a first groove 3, and the end of the charging cable harness 10 is located in the first groove 3; wherein, the other of the mounting portion 30 and the limiting portion 32 covers the opening of the first groove 3 to prevent the end of the charging cable harness 10 from detaching from the first groove 3; in this embodiment, by providing the first groove 3, the entire end of the charging cable harness 10 is located in the first groove 3 and does not come into contact with the external environment, thereby avoiding the possibility of a short circuit at the end of the charging cable harness 10.

[0151] Similarly, since the mounting part 30 or the limiting part 32 covers the opening of the first groove 3, the charging cable harness 10 is not easy to come out of the first groove 3, thereby ensuring that the heat dissipation component 300 can be assembled with the charging cable harness 10.

[0152] Furthermore, since the periphery of the end of the charging cable harness 10 is in contact with the mounting portion 30 and the limiting portion 32, it can achieve a good heat dissipation effect.

[0153] Please see Figure 7 In some embodiments of this application, the first groove 3 is disposed on the limiting portion 32.

[0159] In one embodiment, the entire limiting portion 32 can be completely located within the first groove 3.

[0160] In another embodiment, part of the limiting part 32 is located inside the first groove 3, and the other part is located outside the first groove 3.

[0161] In some embodiments of this application, the first heat sink 311 is made of metal, and the mounting part 30 and the limiting part 32 are both made of insulating material to avoid short circuits between the ends of two adjacent charging cable harnesses 10.

[0164] In another embodiment, the first groove 3 is disposed on the limiting portion 32, so the second heat sink 312 and the third heat sink 313 are both disposed on the limiting portion 32, and at least one of the second heat sink 312 and the third heat sink 313 is located in the first groove 3.

[0165] Since at least one of the second heat sink 312 and the third heat sink 313 is located within the first groove 3, in one embodiment, the second heat sink 312 can be located within the first groove 3; in another embodiment, the third heat sink 313 can be located within the first groove 3; and in yet another embodiment, both the second heat sink 312 and the third heat sink 313 can be located within the first groove 3.

[0168] The second heat sink 312, the third heat sink 313 and the end of the charging cable harness 10 are all located in the first groove 3, which can prevent the components in the heat sink 300 from separating from the end of the charging cable harness 10 after the heat sink 300 is assembled onto the charging gun 1000.
