[0076] 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.
[0077] The charging gun in the relevant technology is powered by DC. Compared with AC power, DC power does not have a natural zero crossing point. Therefore, the DC arc generated by the charging gun is difficult to extinguish naturally, which can easily lead to the ablation of the charging gun material.
[0078] This application proposes a charging gun that can effectively solve the above-mentioned technical problems. Figures 1 to 8 These are some embodiments of this application.
[0079] Please see Figures 1 to 4 In some embodiments of this application, the charging gun includes a charging harness 1, a connecting component 2, and at least one arc-extinguishing component 3. The connecting component 2 enables the charging harness 1 to be energized or de-energized; the arc-extinguishing component 3 is used to extinguish the electric arc generated between the connecting component 2 and the charging harness 1.
[0080] In the technical solution of this application, the connecting component 2 enables the charging harness 1 to be energized or de-energized; and when the charging harness 1 is energized or de-energized, the arc extinguishing component 3 can extinguish the electric arc generated between the connecting component 2 and the charging harness 1, thereby improving the reliability and service life of the charging gun.
[0081] When the charging harness 1 is powered on, the charging gun can be powered on and supply power to external devices; when the charging harness 1 is de-powered, the charging gun is de-powered and cannot supply power to external devices; the power supply of the charging gun is controlled by the connecting component 2, so that no electric arc is generated between the charging gun and the charging port of the external device during the plugging and unplugging process, so as to effectively avoid the generation of cross-current.
[0082] The connecting component 2 allows the charging harness 1 to be powered on or off without restriction.
[0083] In some embodiments of this application, a portion of the structure of the connecting component 2 is electrically connected to the charging harness 1, thereby energizing the charging harness 1 when the connecting component 2 is electrically connected to the charging harness 1, and de-energizing the charging harness 1 when the connecting component 2 is electrically disconnected from the charging harness 1.
[0084] In some other embodiments of this application, the connecting component 2 is not electrically connected to the charging harness 1. For example, if the charging harness 1 includes two parts, the connecting component 2 separates the two parts of the charging harness 1 so that the charging harness 1 is de-energized, and the connecting component 2 makes the two parts of the charging harness 1 contact so that the charging harness 1 is energized.
[0085] It can be understood that since the connection component 2 controls the power supply or power cut-off of the charging harness 1, an electric arc will be generated between the connection component 2 and the charging harness 1.
[0086] In some embodiments of this application, the arc extinguishing component 3 and the connecting component 2 are disposed on the same side; in this embodiment, by setting the arc extinguishing component 3 and the connecting component 2 to be located on the same side, the arc generated between the connecting component 2 and the charging harness 1 can quickly enter the arc extinguishing component 3, shorten the arc's travel distance, and thus improve the arc extinguishing speed.
[0087] In some embodiments of this application, the arc extinguishing component 3 and the connecting component 2 are located on the same side of the charging harness 1.
[0088] In some embodiments of this application, the arc extinguishing component 3 and the connecting component 2 are spaced apart; this arrangement allows the arc to quickly leave the connecting component 2 and allows the arc to be stretched and cooled in the air, thereby improving the service life of the arc extinguishing component 3 and the connecting component 2.
[0089] Please see Figures 5 to 6 In some embodiments of this application, the distance between the arc-extinguishing component 3 and the connecting component 2 is L1; wherein L1 satisfies: 1mm≤L1≤2mm. By setting the value of L1 to satisfy this range, the arc-extinguishing effect of the arc-extinguishing component 3 can be improved, while ensuring the service life of the arc-extinguishing component 3.
[0090] If L1 is less than 1mm, the arc may not be able to stretch sufficiently in the air, resulting in poor arc extinguishing effect of the arc extinguishing component 3. Furthermore, due to the close distance between the arc extinguishing component 3 and the connecting component 2, there may be a burning of the connecting component 2 and the arc extinguishing component 3, which would reduce their service life.
[0091] If L1 is greater than 2mm, the arc may not be able to enter the arc extinguishing component 3 smoothly, resulting in a prolonged arc extinguishing time and thus a poor arc extinguishing effect.
[0092] The value of L1 can be 1mm, 1.05mm, 1.1mm, 1.15mm, 1.2mm, 1.25mm, 1.3mm, 1.35mm, 1.4mm, 1.45mm, 1.5mm, 1.55mm, 1.6mm, 1.65mm, 1.7mm, 1.75mm, 1.8mm, 1.85mm, 1.9mm, 1.95mm, or 2mm. The value of L1 is not limited to the listed values; other unlisted values within this range also apply.
[0093] In some embodiments of this application, the arc extinguishing component 3 includes an arc extinguishing grid 31 and a permanent magnet 32. The arc extinguishing grid 31 is disposed between the permanent magnet 32 and the connecting component 2. In this embodiment, the permanent magnet 32 can attract the electric arc generated between the connecting component 2 and the charging harness 1 to pass through the arc extinguishing grid 31, so that the electric arc is elongated. At the same time, the electric arc will pass through the arc extinguishing grid 31 and be divided into several short arcs during the elongation process, thereby achieving effective arc extinguishing and improving the service life of the charging gun.
[0094] In some embodiments of this application, the interval between the arc-extinguishing grid 31 and the connecting component 2 is L2; wherein, L2 satisfies: 1mm≤L2≤2mm; in this embodiment, by setting the range of L2 to satisfy this range, the arc-extinguishing effect of the arc-extinguishing grid 31 is improved.
[0095] It should be added that after the arc is released, it needs a certain space to stretch in order to reduce its energy density. If L2 is less than 1mm, the arc cannot be stretched sufficiently, which can easily lead to an arc resistance that is too small, making it difficult for the current to decay and extinguish. In addition, the arc temperature is too high and concentrated, which can easily damage the arc extinguishing grid 31, resulting in poor arc extinguishing effect.
[0096] Meanwhile, if L2 is less than 1mm, the arc will be prematurely divided into short arcs, resulting in insufficient voltage gradient on a single grid plate of the arc extinguishing grid 31.
[0097] If L2 is greater than 2mm, the arc will not easily enter the arc-extinguishing grid 31, thus affecting the arc-extinguishing effect; at the same time, if the arc does not enter the arc-extinguishing grid 31 for a long time, the connecting component 2 will be continuously burned, thereby shortening its service life.
[0098] The value of L2 can be 1mm, 1.05mm, 1.1mm, 1.15mm, 1.2mm, 1.25mm, 1.3mm, 1.35mm, 1.4mm, 1.45mm, 1.5mm, 1.55mm, 1.6mm, 1.65mm, 1.7mm, 1.75mm, 1.8mm, 1.85mm, 1.9mm, 1.95mm, or 2mm. The value of L2 is not limited to the listed values; other unlisted values within this range also apply.
[0099] In some embodiments of this application, the distance between the permanent magnet 32 and the connecting component 2 is L3; wherein, L3 satisfies: 10mm≤L3≤20mm; in this embodiment, by setting the value of L3 to satisfy this range, the arrangement of the arc-extinguishing grid 31 between the permanent magnet 32 and the connecting component 2 is facilitated, while ensuring the arc-extinguishing effect of the arc-extinguishing component 3.
[0100] If L3 is less than 10mm, the distance between the permanent magnet 32 and the connecting component 2 is not conducive to the arrangement of the arc extinguishing grid 31. At the same time, because the distance between the permanent magnet 32 and the connecting component 2 is too close, the electric arc may hit the permanent magnet 32, thereby affecting the magnetism of the permanent magnet 32.
[0101] If L3 is greater than 10mm, the arc may not be effectively elongated due to insufficient magnetic field strength of permanent magnet 32, thus prolonging the arcing time and affecting the arc extinguishing effect of arc extinguishing component 3.
[0102] The value of L3 can be 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm, 13.5mm, 14mm, 14.5mm, 15mm, 15.5mm, 16mm, 16.5mm, 17mm, 17.5mm, 18mm, 18.5mm, 19mm, 19.5mm, or 20mm. The value of L3 is not limited to the listed values; other unlisted values within this range also apply.
[0103] In some embodiments of this application, when the charging harness 1 is energized, the current intensity of the charging harness 1 is I, and I satisfies: 200A≤I≤800A; that is, the range value of the distance L1 between the arc extinguishing component 3 and the connecting component 2 in the above embodiments is applicable to charging guns with a charging current intensity between 200A and 800A.
[0104] In some embodiments of this application, when the charging harness 1 is energized, the voltage intensity of the charging harness 1 is U; U satisfies: 200V≤U≤1000V; that is, the range value of the distance L1 between the arc extinguishing component 3 and the connecting component 2 in the above embodiments is applicable to charging guns with charging voltage intensity between 200V and 1000V.
[0105] It is understandable that the range of values for the interval L2 between the arc-extinguishing grid 31 and the connecting component 2, and the range of values for the interval L3 between the permanent magnet 32 and the connecting component 2, are applicable to charging guns with charging current intensity between 200A and 800A or charging voltage intensity between 200V and 1000V.
[0106] Furthermore, the greater the charging current intensity or charging voltage intensity, the more the magnetic field intensity of the permanent magnet 32 needs to be increased or the distance between the permanent magnet 32 and the connecting component 2 needs to be made closer; at the same time, the grid plates of the arc extinguishing grid 31 can be made denser.
[0107] The number of arc-extinguishing components 3 in the embodiments of this application is not limited; there can be one or more, and the design can be made according to actual production.
[0108] In some embodiments of this application, the connecting component 2 includes a first connector 21, which can be electrically connected to or disconnected from the charging harness 1 to energize or de-energize the charging harness 1. In this embodiment, the charging harness 1 is energized or de-energized by the electrical connection or disconnection between the first connector 21 and the charging harness 1. Since the first connector 21 and the charging harness 1 can be electrically connected or disconnected, an electric arc is generated at the part where the first connector 21 and the charging harness 1 can come into contact with or separate from each other. The arc extinguishing component 3 can extinguish the electric arc generated between the first connector 21 and the charging harness 1 when they are electrically connected or disconnected, thereby improving the reliability and service life of the charging gun.
[0109] In some embodiments of this application, L1 is the distance between the arc extinguishing component 3 and the first connector 21.
[0110] In some embodiments of this application, L2 is the spacing distance between the arc extinguishing grid 31 and the first connector 21.
[0111] In some embodiments of this application, L3 is the distance between the permanent magnet 32 and the first connector 21.
[0112] In some embodiments of this application, there are two electrical contact points between the first connector 21 and the charging harness 1. Therefore, two arc extinguishing components 3 are provided inside the charging gun. The two arc extinguishing components 3 are respectively close to the two electrical contact points between the first connector 21 and the charging harness 1, so as to extinguish the electric arc generated between the first connector 21 and the charging harness 1 in a timely manner, thereby improving the service life of the charging gun.
[0113] In some embodiments of this application, two arc-extinguishing components 3 are symmetrically distributed on both sides between the first connector 21 to ensure that the two arc-extinguishing components 3 can extinguish the electric arc generated at the two electrical contact points between the first connector 21 and the charging harness 1.
[0114] In some embodiments of this application, the charging gun further includes an operating mechanism 22, which is used to drive the first connector 21 to electrically connect or disconnect from the charging harness 1. In this embodiment, the user can control the operating mechanism 22 to drive the first connector 21 to electrically connect or disconnect from the charging harness 1, thereby controlling the charging gun to be powered on or off. During the power-on and power-off process of the charging gun, the arc extinguishing component 3 can effectively extinguish the arc generated between the first connector 21 and the charging harness 1, thereby improving the service life of the charging gun.
[0115] Similarly, since the user can control the operating mechanism 22 to drive the first connector 21 to connect or disconnect the electrical connection with the charging cable harness 1, so that the charging gun is powered on or off, the user can control the operating mechanism 22 to disconnect the electrical connection between the first connector 21 and the charging cable harness 1 when the charging gun is in the charging state, and then pull the charging gun out of the charging port. This can effectively prevent the phenomenon of electric shock caused by the charging gun being pulled out while it is charging.
[0116] The form in which the first connector 21 and the charging harness 1 are electrically connected or disconnected is not limited.
[0117] In some embodiments of this application, the operating mechanism 22 can drive the first connector 21 to move relative to the charging harness 1, thereby realizing the electrical connection or disconnection of the first connector 21 and the charging harness 1.
[0118] In some other embodiments of this application, the operating mechanism 22 can drive the first connector 21 to rotate. The first connector 21 and the charging harness 1 are combined to form a knife switch-like structure, thereby realizing the electrical connection or disconnection of the first connector 21 and the charging harness 1.
[0119] Please see Figure 2 and Figure 4 In some embodiments of this application, the first connector 21 is movable relative to the charging harness 1; that is, the first connector 21 can achieve electrical connection with or disconnect from the charging harness 1 by adjusting its position relative to the charging harness 1.
[0120] In some embodiments of this application, the operating mechanism 22 includes a first driving member 221, which is connected to the first connecting member 21 to drive the first connecting member 21 to move closer to or away from the charging cable harness 1. In this embodiment, the user can control the first driving member 221 to move the first connecting member 21 relative to the charging cable harness 1, thereby making the first connecting member 21 electrically connected or disconnected from the charging cable harness 1.
[0121] The manner in which the first driving component 221 drives the first connecting component 21 is not limited.
[0122] In some embodiments of this application, the first drive member 221 can be directly connected to the first connector 21 so that the first connector 21 can be driven to move synchronously through the movement of the first drive member 221.
[0123] In some other embodiments of this application, a transmission component may be provided between the first driving component 221 and the first connecting component 21. The first driving component 221 controls the transmission component to control the movement of the first connecting component 21.
[0124] Please see Figures 1 to 2 In some embodiments of this application, the first driving member 221 is fixedly connected to the first connecting member 21 and can drive the first connecting member 21 to move relative to the charging harness 1. The first driving member 221 has a first position and a second position. When the first driving member 221 is in the first position, the first connecting member 21 is in contact with the charging harness 1 so that the charging harness 1 is energized. When the first driving member 221 is in the second position, the first connecting member 21 is spaced apart from the charging harness 1 so that the charging harness 1 is de-energized. In this embodiment, by providing the first driving member 221 and the first connecting member 21 to be fixedly connected, the movement of the first driving member 221 itself can drive the first connecting member 21 to move so that the first connecting member 21 moves closer to or further away from the charging harness 1, thereby making the first connecting member 21 contact or spaced apart from the charging harness 1, thereby making the first connecting member 21 electrically connected or disconnected from the charging harness 1.
[0125] The switching of the first driving component 221 between the first position and the second position can be controlled manually or mechanically, and no restriction is made here.
[0126] In some embodiments of this application, the first drive member 211 is switched between a first position and a second position by the user manually moving the first drive member 211, thereby electrically connecting or disconnecting the first connector 21 from the charging harness 1.
[0127] In some embodiments of this application, the operating mechanism 22 further includes a first reset member 222, which is connected to the first drive member 221. The first reset member 222 is used to reset the first drive member 221 from the second position to the first position. That is, in this embodiment, the first reset member 222 can ensure that the first connector 21 and the charging harness 1 are always electrically connected, so that the charging gun is in the charging state and will not be disconnected when it is not subjected to external force.
[0128] In some embodiments of this application, the first driving member 221 includes a first connecting part 2211 and a first operating part 2212 connected to each other, the first connecting part 2211 being fixedly connected to the first connecting member 21; the first reset member 222 is disposed between the first operating part 2212 and the housing 4 and the first reset member 222 is an elastic member; in this embodiment, when the user presses the first operating part 2212, the first reset member 222 is compressed, and the first driving member 221 moves from the first position to the second position; when the user releases the first operating part 2212, the first reset member 222 is released, thereby driving the first driving member 221 to move from the second position to the first position.
[0129] In some embodiments of this application, the first reset member 222 includes a spring.
[0130] Please see Figures 3 to 4In some embodiments of this application, the operating mechanism 22 further includes an electromagnetic component 223, which can generate a magnetic field to drive the first connector 21 to be electrically connected or disconnected from the charging harness 1. In this embodiment, the user can control the electromagnetic component 223 to generate a magnetic field to move the first connector 21 relative to the charging harness 1, thereby making the first connector 21 electrically connected or disconnected from the charging harness 1.
[0131] In some embodiments of this application, the electromagnetic component 223 can output kinetic energy to the first connector 21 when the power is turned on or off, so that the first connector 21 can move closer to or away from the charging harness 1, thereby making the first connector 21 electrically connected or disconnected from the charging harness 1.
[0132] In some embodiments of this application, the magnetic field generated by the electromagnetic component 223 can always exist, and the direction of the magnetic field of the electromagnetic component 223 can be controlled so that the first connector 21 can move closer to or away from the charging cable harness 1.
[0133] In some embodiments of this application, the electromagnetic component 223 is capable of generating a magnetic field when energized and not generating a magnetic field when de-energized, thereby enabling the first connector 21 to move closer to or further away from the charging harness 1.
[0134] In some embodiments of this application, the electromagnetic component 223 includes a main body 2231 and a movable part 2232. The main body 2231 is capable of generating a magnetic field when energized. The movable part 2232 is fixedly connected to the first connector 21 and can be driven by the magnetic field generated by the main body 2231 to move relative to the main body 2231. The movable part 2232 moves relative to the main body 2231 so that the first connector 21 is electrically connected to or disconnected from the charging cable harness 1. That is, in this embodiment, the movable part 2232 is the kinetic energy output part of the electromagnetic component 223. The main body 2231 can generate a magnetic field and generate magnetic force to attract the movable part 2232 to move, thereby driving the first connector 21 to move so that the first connector 21 is electrically connected to or disconnected from the charging cable harness 1.
[0135] In some embodiments of this application, the main body 2231 does not generate a magnetic field when it is de-energized.
[0136] In some embodiments of this application, the movable part 2232 has a third position and a fourth position in its travel. When the main body 2231 is powered on, the movable part 2232 is in the third position, and the first connector 21 is electrically connected to the charging cable 1. When the main body 2231 is de-powered, the movable part 2232 is in the fourth position, and the first connector 21 is disconnected from the charging cable 1. That is, in this embodiment, the movable part 2232 can switch between the third position and the fourth position. When the main body 2231 is powered on, the movable part 2232 can move from the fourth position to the third position under the action of a magnetic field, so that the charging cable 1 is powered on. When the main body 2231 is de-powered, the movable part 2232 can reset from the third position to the fourth position, so that the charging cable 1 is de-powered.
[0137] There are no restrictions on the form in which the movable part 2232 resets to the fourth position when the electromagnetic component 223 is de-energized.
[0138] In some embodiments of this application, the electromagnetic component 223 is provided with a spring connected to the first connector 21. When the main body 2231 is energized, the spring is compressed, and the movable part 2232 moves from the fourth position to the third position. When the main body 2231 is de-energized, the spring releases energy, and the movable part 2232 returns to the fourth position from the third position.
[0139] In some other embodiments of this application, the electromagnetic component 223 is provided with a counterweight block that is fixedly connected to the first connector 21. When the main body 2231 is energized, the movable part 2232 overcomes the gravity of the counterweight block and moves from the fourth position to the third position. When the main body 2231 is de-energized, the gravity of the counterweight block drives the movable part 2232 to reset from the third position to the fourth position.
[0140] In some embodiments of this application, the movable part 2232 is magnetic or the component connected to the movable part 2232 is magnetic, thereby enabling the movable part 2232 to move under the drive of a magnetic field.
[0141] In some embodiments of this application, the operating mechanism 22 further includes a second connector 224, which enables the main body 2231 to be powered on or off; that is, the user can control the first connector 21 and the charging harness 1 to be electrically connected or disconnected by controlling the second connector 224 to power on or off the main body 2231.
[0142] The second connector 224 can be an electronic switch or a mechanical switch; no restriction is imposed here.
[0143] In some embodiments of this application, the operating mechanism 22 further includes a second driving member 225, which is connected to the second connecting member 224 to drive the second connecting member 224 to electrically connect or disconnect from the main body 2231. That is, in this embodiment, the user can control the second driving member 225 to move the second connecting member 224 relative to the main body 2231, thereby making the second connecting member 224 electrically connect or disconnect from the main body 2231, and thus controlling the electrical connection or disconnection between the first connecting member 21 and the charging harness 1.
[0144] The manner in which the second driving component 225 drives the second connecting component 224 is not limited.
[0145] In some embodiments of this application, the second drive member 225 can be directly connected to the second connector 224 so that the movement of the second drive member 225 drives the second connector 224 to move synchronously.
[0146] In some other embodiments of this application, a transmission component may be provided between the second driving member 225 and the second connecting member 224. The second driving member 225 controls the transmission component to control the movement of the second connecting member 224.
[0147] In some embodiments of this application, the second driving member 225 is fixedly connected to the second connecting member 224 and can drive the second connecting member 224 to move relative to the main body 2231; the second driving member 225 has a fifth position and a sixth position. When the second driving member 225 is in the fifth position, the second connecting member 224 is in contact with the main body 2231, so that the main body 2231 is energized; when the second driving member 225 is in the sixth position, the second connecting member 224 is spaced apart from the main body 2231, so that the main body 2231 is de-energized; in this embodiment, by providing the second driving member 225 and the second connecting member 224 to be fixedly connected, the movement of the second driving member 225 itself can drive the second connecting member 224 to move, so that the second connecting member 224 moves closer to or further away from the main body 2231, thereby making the second connecting member 224 contact or spaced apart from the main body 2231, thereby making the second connecting member 224 electrically connected or disconnected from the main body 2231.
[0148] The switching of the second drive unit 225 between the fifth and sixth positions can be controlled manually or mechanically, and no restriction is imposed here.
[0149] In some embodiments of this application, the second drive member 225 is switched between a fifth position and a sixth position by the user manually moving the second drive member 225, thereby electrically connecting or disconnecting the second connector 224 from the main body 2231.
[0150] In some embodiments of this application, the operating mechanism 22 further includes a second reset member 226, which is connected to the second drive member 225. The second reset member 226 is used to reset the second drive member 225 from the sixth position to the fifth position. That is, in this embodiment, the second reset member 226 can ensure that the second connector 224 and the main body 2231 are always electrically connected, so that the charging gun is in a charging state and will not be powered off when it is not subjected to external force.
[0151] In some embodiments of this application, the second driving member 225 includes a second connecting portion 2251 and a second operating portion 2252 connected to each other, the second connecting portion 2251 being fixedly connected to the second connecting member 224; the second reset member 226 is disposed between the second operating portion 2252 and the housing 4 and is an elastic member; in this embodiment, when the user presses the second operating portion 2252, the second reset member 226 is compressed, and the second driving member 225 moves from the fifth position to the sixth position; when the user releases the second operating portion 2252, the second reset member 226 is released, thereby driving the second driving member 225 to reset from the sixth position to the fifth position.
[0152] In some embodiments of this application, the second reset member 226 includes a spring.
[0153] In some embodiments of this application, the main body 2231 includes a coil 2231A and a wire 2231B. The coil 2231A is configured to generate a magnetic force when energized to drive the movable part 2232 to move. The wire 2231B is electrically connected to the coil 2231A, and the second connector 224 can be electrically connected to or disconnected from the wire 2231B. When the second connector 224 is electrically connected to the wire 2231B, the wire 2231B and the coil 2231A are energized, the coil 2231A generates a magnetic field and a magnetic force to drive the movable part 2232 to move. At this time, the first connector 21 is electrically connected to the charging harness 1. When the second connector 224 is disconnected from the wire 2231B, the wire 2231B and the coil 2231A are de-energized, the coil 2231A does not generate a magnetic field, the movable part 2232 is reset, and the first connector 21 is disconnected from the charging harness 1.
[0154] In some embodiments of this application, the main body 2231 also includes a power supply 2231C, which is connected to the wire 2231B, thereby enabling it to supply power to the coil 2231A and the wire 2231B.
[0155] In some embodiments of this application, the power supply 2231C is a 12V power supply.
[0156] In some embodiments of this application, the first connector 21 is disposed on the same side as the arc extinguishing component 3. In this embodiment, by setting the arc extinguishing component 3 and the first connector 21 to be on the same side, the arc generated between the first connector 21 and the charging harness 1 can quickly enter the arc extinguishing component 3, shortening the arc's travel distance and thereby improving the arc extinguishing speed.
[0157] In some embodiments of this application, the charging gun may also simultaneously include a first driving member 221, an electromagnetic component 223, and a second driving member 225; wherein the first driving member 221 and the electromagnetic component 223 are both used to drive the first connector 21 to electrically connect or disconnect from the charging harness 1, and the second driving member 225 is used to drive the second connector 224 to electrically connect or disconnect from the main body 2231, so that the electromagnetic component 223 is energized or de-energized. A detailed description follows.
[0158] When the first driving member 221 is in the first position and the movable part 2232 is in the third position, the first connecting member 21 is electrically connected to the charging harness 1 so that the charging harness 1 is powered on; at this time, the second driving member 225 is in the fifth position.
[0159] If it is necessary to switch the charging harness 1 from the powered-on state to the powered-off state, it can be done by controlling at least one of the first driving member 221 and the second driving member 225.
[0160] If the user controls the first driving member 221 to switch from the first position to the second position, the first connecting member 21 will move to de-energize the charging harness 1. If the second driving member 225 is still in the fifth position, the first driving member 221 will need to overcome the resistance generated by the attraction or repulsion between the main body 2231 and the moving part 2232 in the electromagnetic component 223 to switch from the third position to the fourth position.
[0161] If the user controls the second drive member 225 to switch from the fifth position to the sixth position, the movable part 2232 will switch from the third position to the fourth position, causing the first connector 21 to move and de-energize the charging cable harness 1. Since the first drive member 221 is fixedly connected to the charging cable harness 1, the first drive member 221 will also switch from the first position to the second position. Of course, the movement of the movable part 2232 from the third position to the fourth position must overcome the resistance provided by the first reset member 222.
[0162] Similarly, the user can also drive the first driving component 221 and the second driving component 225 at the same time to switch the charging harness 1 from the power-on state to the power-off state. Since the method by which the first driving component 221 and the second driving component 225 drive the charging harness 1 from the power-on state to the power-off state has been explained above, it will not be repeated here.
[0163] It is understandable that since the main body 2231 drives the movable part 2232 by magnetic force, the movable part 2232 will not cause structural interference with the main body 2231 when it is in motion. Therefore, when the charging harness is in a de-energized state, the second drive member 225 can be in the fifth position or the sixth position, as long as the movement of the first connector 21 can overcome the resistance between the main body 2231 and the movable part 2232.
[0164] In some embodiments of this application, the charging gun is equipped with a first driving component 221 and an electromagnetic component 223. The power supply to and from the electromagnetic component 223 is controlled by a second connector 224, which is an electronic switch.
[0165] At this time, the user can drive the first connector 21 to move through electronic control or manual control, and make the charging harness 1 powered on or off.
[0166] When the user controls the first drive unit 221 to drive the first connector 21 to move, the charging harness 1 is energized when the first drive unit 221 is in the first position; at this time, the electronic switch can energize or de-energize the electromagnetic component 223.
[0167] When the user drives the first connector 21 to move by controlling the electronic switch, the charging cable 1 is energized when the active part 2232 is in the third position and the first driving member 221 is in the first position; when the active part 2232 is in the fourth position, the charging cable 1 is de-energized and the first driving member 221 is in the second position.
[0168] In some embodiments of this application, the first connector 21 and the arc extinguishing component 3 are located on the same side of the charging harness 1.
[0169] In some embodiments of this application, the charging gun further includes a housing 4, which has a chamber 41. A portion of the charging harness 1, the first connector 21, and the arc extinguishing assembly 3 are all located in the chamber 41. The chamber 41 is an insulating chamber. The first connector 21 and the arc extinguishing assembly 3 are disposed in the chamber 41 to extinguish the arc inside the housing 4, thereby preventing the occurrence of cross-current.
[0170] In some embodiments of this application, the chamber 41 is formed by a ceramic enclosure.
[0171] In some embodiments of this application, the chamber 41 is filled with hydrogen gas; wherein, hydrogen gas has good arc-quenching properties to improve the reliability and service life of the charging gun.
[0172] In some embodiments of this application, the operating mechanism 22 may be disposed outside the chamber 41 to drive the first connector 21, or it may be at least partially disposed inside the chamber 41 to drive the first connector 21, without limitation.
[0173] In some embodiments of this application, a portion of the operating mechanism 22 is disposed within the chamber 41; wherein, the portion of the operating mechanism 22 disposed within the chamber 41 is used to drive the first connector 21 to electrically connect or disconnect from the charging harness 1; in this embodiment, by setting a portion of the operating mechanism 22 within the chamber 41, it is convenient to drive the first connector 21 to electrically connect or disconnect from the charging harness 1.
[0174] In some embodiments of this application, another part of the operating mechanism 22 is located outside the chamber 41. The charging gun also includes at least one latching part 5, which is connected to the part of the operating mechanism 22 located outside the chamber 41. When the first connector 21 is electrically connected to the charging harness 1, the latching part 5 is used to latch with the charging port of the external device. When the first connector 21 is disconnected from the charging harness 1, the latching part 5 is used to unlatch from the charging port of the external device. That is, in this embodiment, the latching part 5 is designed so that the charging gun can be securely latched with the charging port of the external device during charging. At the same time, when the user needs to pull the charging gun out of the charging port of the device, the latching part 5 must be controlled to unlatch from the charging port of the device. When the latching part 5 is unlatched from the charging port of the device, the electrical connection between the first connector 21 and the charging harness 1 will be disconnected to ensure the safety of the charging gun.
[0175] Please see Figure 1 , Figure 2 and Figure 7 In some embodiments of this application, a portion of the first driving member 221 is located within the chamber 41 for driving the first connector 21 to electrically connect or disconnect from the charging harness 1. Another portion of the first driving member 221 is located outside the housing 4 for user operation. The first operating part 2212 in the first driving member 221 is rotatably mounted on the housing 4, and the latching part 5 is connected to the first operating part 2212. That is, in this embodiment, the rotation of the first operating part 2212 can control whether the latching part 5 latches with the charging port of the external device, and the rotation of the first operating part 2212 can also control whether the first connector 21 is electrically connected to the charging harness 1. In other words, the first operating part 2212 can simultaneously control the latching part 5 and the first connector 21 to ensure the safety of the charging gun.
[0176] Please see Figure 3 , Figure 4 and Figure 8In some embodiments of this application, a portion of the electromagnetic component 223 and the second driving member 225 is located within the chamber 41 to drive the first connector 21 to electrically connect or disconnect from the charging harness 1. Another portion of the second driving member 225 is located outside the housing 4 for user operation. The second operating part 2252 in the second driving member 225 is rotatably mounted on the housing 4, and the latching part 5 is connected to the second operating part 2252. That is, in this embodiment, the rotation of the second operating part 2252 can control whether the latching part 5 latches with the charging port of the external device, and at the same time, the rotation of the second operating part 2252 can also control whether the first connector 21 is electrically connected to the charging harness 1. In other words, the second operating part 2252 can simultaneously control the latching part 5 and the first connector 21 to ensure the safety of the charging gun.
[0177] In some embodiments of this application, the charging harness 1 includes a first sub-segment 11 and a second sub-segment 12 spaced apart from each other; when the charging harness 1 is powered on, the connecting component 2 connects the first sub-segment 11 and the second sub-segment 12; when the charging harness 1 is powered off, the connecting component 2 is separated from at least one of the first sub-segment 11 and the second sub-segment 12; in this embodiment, by setting the connecting component 2 to disconnect the physical contact with at least one of the first sub-segment 11 and the second sub-segment 1, the connecting component 2 is disconnected from the charging harness 1, that is, the charging harness 1 is powered off.
[0178] The first sub-segment 11 and a portion of the second sub-segment 12 are located within the chamber 41, so that the connection or disconnection between the first sub-segment 11, the second sub-segment and the first connector 21 can be operated within the chamber 41, and arc extinguishing can be performed within the chamber 41.
[0179] It should be noted that there are no restrictions on the devices that the charging gun in this application embodiment can be used with; the devices can be vehicles, aircraft, electronic products, etc.
