[0053] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0054] Reference will be made below Figures 1 - 20 to describe the contactor 100, vehicle 1000, and charging pile 2000 according to embodiments of the present invention.

[0055] As Figures 1 - 5 shown, the contactor 100 according to an embodiment of the present invention includes: a terminal 10, a conduction member 20, and a driving assembly 30.

[0056] Among them, the terminal 10 includes: a first terminal 11, a second terminal 12, and a third terminal 13; the driving assembly 30 includes: a first driving coil 31, a second driving coil 32, and a microswitch 33. The microswitch 33 is rotatably disposed between the first driving coil 31 and the second driving coil 32. The microswitch 33 is connected to the conduction member 20 and is adapted to drive the conduction member 20 to switch between a first position and a second position under the magnetic force of the first driving coil 31 and the second driving coil 32.

[0057] As Figure 3 , Figure 4 and Figure 5 shown, the conduction member 20 has a first conduction section 21, a second conduction section 22, and a third conduction section 23. When the conduction member 20 is in the first position, the first conduction section 21 is electrically connected to the first terminal 11, and the third conduction section 23 is electrically connected to the second terminal 12. When the conduction member 20 is in the second position, the second conduction section 22 is electrically connected to the first terminal 11, and the third conduction section 23 is electrically connected to the third terminal 13.

[0058] Specifically, the first conduction section 21, the second conduction section 22, and the third conduction section 23 of the conduction member 20 cooperate with the first terminal 11, the second terminal 12, and the third terminal 13 of the terminal 10, and can be correspondingly configured as a switch circuit with one input terminal and two output terminals or configured as a switch circuit with one output terminal and two input terminals, which can simplify the circuit connected to the high-voltage conduction part. By using a single-pole double-throw contactor to achieve the functions of multiple contactors 100, the structure of the contactor 100 can be simplified, the space occupied by the contactor 100 can be reduced, and while reducing the production cost of the contactor 100, the number of terminals 10 (i.e., the number of contacts) can be reduced.

[0059] More importantly, the microswitch 33 is driven by the first driving coil 31 and the second driving coil 32 located on both sides of the microswitch 33, which can make full use of the width space between the first terminal 11, the second terminal 12 and the third terminal 13. Not only can the sizes of the two driving coils be set smaller, which can further improve the space occupation of the contactor 100, but also the stroke of the microswitch 33 can be achieved by adjusting the distance between the first driving coil 31 and the second driving coil 32. The fine movement stroke adjustment of the microswitch 33 is simpler and more convenient and can be adjusted according to the usage requirements.

[0060] It should be noted that the first conduction section 21 and the second conduction section 22 are selectively electrically connected to the first terminal 11 on both sides of the first terminal 11, which can increase the movement stroke of the conduction member 20 and reduce the probability of adhesion between the first conduction section 21 and the first terminal 11 and between the second conduction section 22 and the first terminal 11 during the operation of the contactor 100.

[0061] For the contactor 100 according to the embodiment of the present invention, on the one hand, compared with the technical solution of a plurality of independently arranged contactors 100, the number of contact points can be reduced, while reducing the risk points and power losses, the circuit where the contactor 100 is located can be simplified, the structure of the contactor 100 can be simplified, and the space occupation of the contactor 100 can be reduced, so as to reduce the production cost of the contactor 100 and reduce the layout difficulty; on the other hand, by driving the rotation of the microswitch 33 through two driving coils, not only can the volumes of the first driving coil 31 and the second driving coil 32 be set smaller, which can further improve the space occupation of the contactor 100, but also the stroke adjustment of the microswitch 33 can be realized by adjusting the distance between the first driving coil 31 and the second driving coil 32, which can improve the applicable range of the contactor 100, and a reasonable stroke of the microswitch 33 can reduce the probability of arcing and adhesion, ensuring the reliability of the contactor 100.

[0062] It should be pointed out that reducing the risk points and power losses means that the number of terminals 10 is less than that in the prior art, which can reduce the high-voltage loss, the number of arcing and the adhesion points caused by the moving contact, and at the same time reduce the wear caused by the operation of the contactor 100.

[0063] In some embodiments, the distance between the rotation center of the microswitch 33 and any end of the microswitch 33 is less than the distance between the contact point of the first conduction section 21 and the first terminal 11 and the rotation center of the microswitch 33, the distance between the contact point of the second conduction section 22 and the first terminal 11 and the rotation center of the microswitch 33, the distance between the contact point of the third conduction section 23 and the second terminal 12 and the rotation center of the microswitch 33, and the distance between the contact point of the third conduction section 23 and the third terminal 13 and the rotation center of the microswitch 33.

[0064] That is to say, the maximum distance from the rotation center of the microswitch 33 to any one end thereof is L1, the distance from the rotation center of the microswitch 33 to the contact point between the first terminal 11 and the first conduction section 21 is L2, the distance from the rotation center of the microswitch 33 to the contact point between the second terminal 12 and the first conduction section 21 is L3, the distance from the rotation center of the microswitch 33 to the contact point between the second terminal 12 and the third conduction section 23 is L4, and the distance from the rotation center of the microswitch 33 to the contact point between the third terminal 13 and the third conduction section 23 is L5. It should satisfy L1 < L2, L1 < L3, L1 < L4, and L1 < L5. In this way, the movement stroke of the conduction member 20 driving the third conduction section 23 is greater than the movement stroke of the microswitch 33, which can magnify the stroke of the microswitch 33 to meet the electrical clearance requirements of the high-voltage circuit connected to the contactor 100.

[0065] As Figure 2 and Figure 3 shown, the conduction member 20 and the terminal 10 are oppositely arranged in the first direction, and the driving assembly 30 and the conduction member 20 are oppositely arranged in the second direction, and the first direction is orthogonal to the second direction.

[0066] Exemplarily, the first direction can be the length direction or the width direction in the horizontal direction, and the second direction correspondingly is the height direction. In the contactor 100 of the embodiment of the present invention, the terminal 10 and the conduction member 20 are arranged at the same height, and the driving assembly 30 is arranged below or above the terminal 10 and the conduction member 20, which can reduce the probability of the contactor 100 being easily broken from the middle during long-term vibration on the vehicle, improve the service life and working stability of the contactor 100, and by hierarchically arranging the contactor 100 in the up and down direction, high-voltage and low-voltage isolation can be achieved (the upper part is the high-voltage conduction part, and the lower part is the low-voltage control part).

[0067] Thus, the arc extinguishing method of the contactor 100 is no longer limited to the form of cooperation between inert gas and magnetic blow arc extinguishing. It can also be achieved by the way of immersion in insulating liquid or without setting an arc extinguishing structure. Based on the diversity of arc extinguishing methods, there is no need to perform insulation isolation on the driving coil, which can solve the low-voltage failure problem. And because there is no need to inject inert gas, there is no need to use the ceramic and metal brazing process for the processing of the contactor 100, which can also simplify the processing process of the contactor 100, reduce the material process, improve the production efficiency, and reduce the processing cost of the contactor 100.

[0068] As Figure 4 and Figure 5As shown, in some embodiments, when the conducting member 20 is in the first position, the first conducting section 21 is electrically connected to the first terminal 11 on one side of the first terminal 11. When the conducting member 20 is in the second position, the second conducting section 22 is electrically connected to the first terminal 11 on the other side of the first terminal 11. In this way, the movement stroke during the electrical connection between the first terminal 11 and the conducting member 20 can be amplified, further reducing the probability of adhesion.

[0069] In some embodiments, during the process of the contactor 100 controlling the circuit, the opposite sides of the first conducting section 21 and the second conducting section 22 will impact the first terminal 11 during movement, and the third conducting section 23 will impact the second terminal 12 or the third terminal 13, generating working noise. To reduce the working noise of the contactor 100, a flexible metal material (e.g., soft copper composite material, soft silver composite material) can be used or a flexible metal material can be provided at the part where the conducting section contacts the terminal 10 to reduce the impact noise and improve the user experience of the contactor 100. At the same time, the technical problems of large contact resistance and high adhesion probability between the conducting member 20 and the terminal 10 can be improved.

[0070] As Figure 6 、 Figure 7 and Figure 8 shown, according to some embodiments of the present invention, the microswitch 33 includes: a body portion 331 and permanent magnets 332 located at both ends of the body portion 331. The two permanent magnets 332 can selectively magnetically attract to the first drive coil 31 or the second drive coil 32.

[0071] In this way, under the Lorentz force of the first drive coil 31 and the second drive coil 32, the permanent magnet 332 can drive the body portion 331 of the microswitch 33 to move. The body portion 331 drives the conducting member 20 to move to switch between the first position and the second position. When the conducting member 20 is in the first position or the second position, the permanent magnets 332 at both ends are respectively magnetically adsorbed on the corresponding drive coils, that is, the closed state between the terminal 10 and the corresponding conducting section can be maintained by the magnetic force of the permanent magnet 332, and there is no need to continuously energize the first drive coil 31 and the second drive coil 32, which can reduce the power consumption of the low-voltage control part and improve the energy consumption of the contactor 100.

[0072] More importantly, the microswitch 33 of the present invention is configured in a straight shape, that is, a permanent magnet 332 is provided at each end of the plate-shaped body portion 331. By adjusting the distance between the first drive coil 31 and the second drive coil 32, the rotation stroke of the microswitch 33 can be adjusted, and then the rotation stroke of the conducting member 20 can be adjusted to ensure the working reliability of the contactor 100.

[0073] In Figure 9 and Figure 10In the specific embodiments shown, the first driving coil 31 and the second driving coil 32 are arranged in series, and magnetic conductive sheets 34 are arranged at both ends of the sides facing each other. The two permanent magnets 332 can be selectively magnetically attracted to the magnetic conductive sheet 34 of the first driving coil 31 or the magnetic conductive sheet 34 of the second driving coil 32. The magnetic conductive sheet 34 is generally L-shaped, with one end connected to the end of the driving coil, and the other ends of the two magnetic conductive sheets 34 at both ends of the same driving coil extend towards each other, making the structure of the driving coil and the microswitch 33 more reasonable, and only magnetic attraction to the magnetic conductive sheet 34 is required.

[0074] It can be understood that the polarities of the ends of the two permanent magnets 332 facing away from each other are the same, and in the energized state, the polarities of the first driving coil 31 and the second driving coil 32 are opposite.

[0075] Exemplarily, as Figure 10 shown, the polarity of the permanent magnet 332 at one end of the body portion 331 is N - S pole, and the polarity of the permanent magnet 332 at the other end of the body portion 331 is S - N pole, that is, the magnetic poles of the two permanent magnets 332 facing the body portion 331 at one end are S pole, S pole respectively, and the magnetic poles of the ends facing away from each other are N pole, N pole respectively; in the energized state, the current can flow from the first driving coil 31 to the second driving coil 32. At this time, the polarity of one end of the first driving coil 31 is N pole and the other end is S pole, and the magnetic pole of the same - side end of the second driving coil 32 is S pole and the magnetic pole of the other same - side end is N pole. When the current flows from the second driving coil 32 to the first driving coil 31, the polarities of the two driving coils are exactly opposite.

[0076] In this way, when the conducting member 20 is in the first position, the permanent magnet 332 at one end of the microswitch 33 is magnetically attracted to the first driving coil 31, and the permanent magnet 332 at the other end is magnetically attracted to the second driving coil 32; when the conducting member 20 is in the second position, the permanent magnet 332 at one end of the microswitch 33 is magnetically attracted to the second driving coil 32, and the permanent magnet 332 at the other end is magnetically attracted to the first driving coil 31. As Figure 9 、 Figure 10 and Figure 12 shown, according to some embodiments of the present invention, a receiving groove a is provided on the body portion 331, and the conducting member 20 is arranged in the receiving groove a.

[0077] Specifically, the receiving groove a includes: a first groove portion a1, a second groove portion a2, and a third groove portion a3. The first groove portion a1, the second groove portion a2, and the third groove portion a3 are communicated with each other and are respectively used to accommodate the first conducting segment 21, the second conducting segment 22, and the third conducting segment 23. In this way, the fixing stability of the conducting member 20 on the microswitch 33 can be improved, so as to improve the stability of the synchronous movement of the two, avoid the conducting member 20 from moving around, and improve the working stability and reliability of the contactor 100.

[0078] Of course, the cooperation between the drive coil of the present application and the microswitch 33 is not limited to the above structure. Refer to Figure 11 As shown, in some other embodiments, the magnetic poles of the two permanent magnets 332 are located in the thickness direction of the body portion 331, and the polarities of the same side of the two permanent magnets 332 are the same. In the energized state, the polarities of the same side ends of the first drive coil 31 and the second drive coil 32 are the same, and the same technical effects as those of the above embodiments can also be achieved, which will not be elaborated here.

[0079] It can be understood that the conducting member 20 can be configured in a Y shape, a △ shape, or a T shape, and the present invention does not make specific limitations.

[0080] Furthermore, the body portion 331 is configured as an insulating member, or an insulating layer is coated in the accommodation groove a. In this way, the high-voltage isolation effect between the high-voltage conducting part and the low-voltage control part can be improved, the low-voltage failure caused by high-voltage breakdown can be avoided, and the working stability of the contactor 100 can be improved.

[0081] As Figure 1 and Figure 2 shown, in some embodiments, the contactor 100 further includes: a housing 40, the housing 40 defines an accommodation space, the terminal 10, the conducting member 20, and the drive assembly 30 are all arranged in the accommodation space, and at least a part of the terminal 10 extends out of the housing 40. In this way, through the arrangement of the housing 40, the terminal 10, the conducting member 20, and the drive assembly 30 can be separated from the outside world, and while improving the working stability, the interference of the external environment on the first drive coil 31 and the second drive coil 32 can be reduced, and the control response efficiency of the low-voltage control part can be improved.

[0082] Furthermore, a low-voltage signal terminal 50 is also arranged outside the housing 40, and the low-voltage signal terminal 50 is detachably arranged on the housing 40 and electrically connected to the first drive coil 31 or the second drive coil 32. It can be understood that, in some embodiments, the housing 40 is provided with a wire harness outlet, the part of the low-voltage signal terminal 50 extending into the housing 40 is electrically connected to the first drive coil 31 or the second drive coil 32, and the other end is led out of the housing 40 through the wire harness outlet. In some other embodiments, the low-voltage signal terminal 50 is fixed on the housing 40 in a plug-in form, a plug-in interface is correspondingly arranged on the housing 40, the plug-in interface is electrically connected to the first drive coil 31 or the second drive coil 32, and the plug-in interface is in plug-in fit with the low-voltage signal terminal 50, so that the appearance of the contactor 100 of the present invention is consistent with that of the traditional contactor 100, which is convenient for structural design and material switching, and can reduce the R & D cycle and development cost.

[0083] It should be noted that the contactor 100 of the present invention is not limited to the above structural form. In some other embodiments, by changing the plane where the installation angular coordinates of the contactor 100 are located, it can also be formed into a "horizontal" contactor 100 to change the position of the insulating medium in the housing 40 of the contactor 100 and optimize the electrical clearance distance.

[0084] According to some embodiments of the present invention, the contactor 100 further includes a sensor. The sensor is adjacent to the first terminal 11 or the second terminal 12 or the third terminal 13 or the conducting member 20 and is used to detect in real time the circuit signals of the first terminal 11 or the second terminal 12 or the third terminal 13 or the conducting member 20, where the circuit signals include: temperature change, voltage change, and current change.

[0085] In this way, by setting the sensor, as the first terminal 11 and the second terminal 12 or the third terminal 13 are conducted through the conducting member 20, both the current and the heat generation in the high-voltage circuit will change, and correspondingly, a temperature change will occur. The sensor can obtain the change information (such as temperature change, current change, etc.) during the operation of the high-voltage circuit and transmit it to the corresponding controller in the form of circuit signals. The controller determines whether the cut-off threshold of the high-voltage circuit (temperature threshold, voltage threshold, current threshold) is reached according to the circuit signals, and when it is necessary to disconnect the high-voltage circuit, controls other positions in the circuit where the contactor 100 is located to disconnect (for example, controls other contactors to disconnect). This not only eliminates the need to set a fuse to reduce high-voltage loss and cost, but also ensures that the electrical equipment can be powered by high voltage when the electrical equipment using the contactor 100 of the present invention needs to continue to work after the control circuit is disconnected, which can improve safety.

[0086] It should be noted that after the fuse melts, the high-voltage circuit is completely disconnected. However, in the present invention, by setting a controller and a sensor, even if it is necessary to disconnect the high-voltage power based on the information obtained by the sensor, under extreme conditions, high-voltage power can still be applied to improve safety. For example, when the contactor 100 of the present invention is applied to a vehicle 1000, when the circuit information indicates that the contactor 100 needs to be disconnected but the vehicle 1000 is in a dangerous situation and needs to maintain the working condition, the high-voltage power-on state can be maintained, and after driving to a safe position or after the dangerous situation is eliminated, other positions in the circuit where the contactor 100 is located are controlled to disconnect.

[0087] According to some embodiments of the present invention, the first terminal 11 is configured as an input terminal, and the second terminal 12 and the third terminal 13 are configured as output terminals; or the first terminal 11 is configured as an output terminal, and the second terminal 12 and the third terminal 13 are configured as input terminals.

[0088] That is to say, in some embodiments, the contactor 100 of the present invention can be connected to a working circuit having one input terminal and two output terminals; in other embodiments, the contactor 100 of the present invention can be connected to a working circuit in which one output terminal corresponds to two input terminals, reducing the number of contactors 100 and simplifying the high-voltage circuit to which the high-voltage conduction part is connected.

[0089] As Figure 16 , Figure 17 and Figure 18 shown, the first connection terminal 11 includes a first connection end 111 and a first interface 112 that are connected to each other, the second connection terminal 12 includes a second connection end 121 and a second interface 122 that are connected to each other, the third connection terminal 13 includes a third connection end 131 and a third interface 132 that are connected to each other, the first connection end 111 is electrically connected to the first conduction segment 21 or the second conduction segment 22, the second connection end 121 and the third connection end 131 are selectively connected to the third conduction segment 23, and the first interface 112, the second interface 122, and the third interface 132 are all configured as multiple.

[0090] That is to say, the contactor 100 of the present application can control multiple electrical devices through the same contactor 100, and multiple interfaces can be provided at each connection terminal to further simplify the circuit where the multiple electrical devices are located.

[0091] As Figure 20 shown, the charging pile 2000 according to an embodiment of the present invention includes the contactor 100 in the above embodiment.

[0092] The charging pile 2000 according to an embodiment of the present invention adopts the above contactor 100, and the technical effects are the same as those of the above contactor 100, which will not be elaborated here.

[0093] As Figure 19 shown, the vehicle 1000 according to an embodiment of the present invention includes the contactor 100 in the above embodiment.

[0094] The vehicle 1000 according to an embodiment of the present invention adopts the above contactor 100, and the technical effects are the same as those of the above contactor 100, which will not be elaborated here.

[0095] Referring to Figures 13 - 15 shown, there may be several usage scenarios when the vehicle 1000 of the present invention adopts the above contactor 100.

[0096] As Figure 13As shown, in the usage scenario where the in-vehicle discharge socket and the out-vehicle discharge socket cannot be used with loads simultaneously, the on-vehicle charger and the DC / DC converter are electrically connected to the first terminal 11 through a wire harness. The second terminal 12 is electrically connected to the in-vehicle discharge socket, and the third terminal 13 is electrically connected to the out-vehicle discharge socket. To control the conduction between the first terminal 11 and the second terminal 12 or the third terminal 13 through the low-voltage control part, the in-vehicle discharge socket with a load or the out-vehicle discharge socket with a load can be realized respectively, avoiding the phenomenon that the in-vehicle discharge socket and the out-vehicle discharge socket are connected to loads simultaneously, and improving the usage safety.

[0097] As Figure 14 shown, in the usage scenario where the DC charging socket charges the battery pack, the charging voltages of the DC charging guns equipped with different charging piles are different. Some charging guns can directly charge the battery pack, while some other charging guns need to be boosted before charging. Correspondingly, the DC charging socket can be electrically connected to the first terminal 11, the second terminal 12 is electrically connected to the battery pack and a DC boosting circuit is arranged thereon, and the third terminal 13 is directly electrically connected to the battery pack. When charging with a charging gun that needs to be boosted, the first terminal 11 and the second terminal 12 are conducted to charge after boosting. When charging without boosting, the first terminal 11 and the third terminal 13 are conducted through the conducting part 20, which can improve the adaptability of the vehicle 1000, ensure that charging guns of different specifications and sizes can be charged, and can reduce unnecessary high-voltage power loss.

[0098] As Figure 15 shown, for the vehicle's dual-motor solution, when borrowing the dual-motor windings for DC charging boosting, in order to improve the service life of the motors, in the usage scenario where the two motors are mutually replaced for DC charging boosting, the contactor 100 of the present invention can be used to control the switching between the two motors, avoiding overheating of the motor windings of a certain motor during the boosting process and extending the service life of the motors.
