Technical Field

[0001] The present invention relates to the field of contactors, and in particular to a contactor, a charging pile and a vehicle. Background Art

[0002] The rapid development of applied science and technology and the ever-changing industrial transformation are placing higher demands on the rapidly evolving vehicle. Vehicle components are becoming increasingly modular, integrated, and intelligent. On this basis, there is a growing demand for products with higher performance, enhanced safety, more convenient control, smaller size, and lighter weight.

[0003] In existing vehicle power distribution systems, in order to avoid mutual influence between multiple electrical components, multiple contactors are independently set up, resulting in complex circuit layout, large space occupation and high cost. Summary of the Invention

[0052] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0053] Reference below Figures 1-20 The contactor 100 , the vehicle 1000 , and the charging pile 2000 according to an embodiment of the present invention are described.

[0054] like Figure 1-Figure 5 As shown, the contactor 100 according to the embodiment of the present invention includes: a terminal 10 , a conducting member 20 and a driving assembly 30 .

[0055] Among them, the terminal 10 includes: a first terminal 11, a second terminal 12 and a third terminal 13; the conductive member 20 has a first conductive section 21 and a second conductive section 22, the first conductive section 21 and the second conductive section 22 are conductively connected and can rotate relative to each other, and the first conductive section 21 is fixed to the first terminal 11; the driving component 30 includes: a first driving coil 31, a second driving coil 32 and a micro switch 33, the micro switch 33 is rotatably arranged between the first driving coil 31 and the second driving coil 32, the micro switch 33 is connected to the conductive member 20, and is suitable for driving the second conductive section 22 to be selectively electrically connected to the second terminal 12 or the third terminal 13 under the action of the magnetic force of the first driving coil 31 and the second driving coil 32.

[0056] like Figure 3 、 Figure 4 and Figure 5 As shown, the conductive member 20 has a first conductive section 21 and a second conductive section 22, and the contactor 100 has a first position in which the first terminal 11 and the second terminal 12 are electrically connected via the conductive member 20, and a second position in which the first terminal 11 and the third terminal 13 are connected via the conductive member 20. In the first position, the first conductive section 21 is fixed to the first terminal 11, and the second conductive section 22 is electrically connected to the second terminal 12. In the second position, the first conductive section 21 is fixed to the first terminal 11, and the second conductive section 22 is electrically connected to the third terminal 13.

[0057] Specifically, the first conductive section 21 and the second conductive section 22 of the conductive member 20 cooperate with the first terminal 11, the second terminal 12 and the third terminal 13 of the terminal 10, and can be configured as a switching circuit with one input terminal and two output terminals or as a switching circuit with one output terminal and two input terminals. This can simplify the circuit and realize the functions of multiple contactors 100 through a single-pole double-throw contactor, simplify the structure of the contactor 100, reduce the space occupied by the contactor 100, reduce the production cost of the contactor 100, and at the same time reduce the number of terminals 10 (i.e., the number of contacts).

[0058] More importantly, the micro switch 33 is driven by the first drive coil 31 and the second drive coil 32 located on both sides of the micro switch 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 drive coils be set smaller, which can further improve the space occupied by the contactor 100, but the stroke of the micro switch 33 can be achieved by adjusting the distance between the first drive coil 31 and the second drive coil 32. The micro stroke adjustment of the micro switch 33 is simpler and more convenient, and can be adjusted according to usage requirements.

[0059] It should be noted that the relative rotation of the first conductive section 21 and the second conductive section 22 means that they can be connected by a conductive rotating connection structure to achieve relative rotation. Alternatively, they can be connected by a flexible structural member (i.e., at least a portion of the conductive member 20 is constructed as a flexible structure) and relative rotation can be achieved by bending the flexible structure. Alternatively, the conductive member 20 can be constructed as an entire flexible member and relative rotation can be achieved by bending. With this structure, the bending wear of the conductive member 20 is reduced during the rotation of the second conductive section 22, which can extend the service life of the conductive member 20 and thus improve the service life of the contactor 100.

[0060] According to the contactor 100 of the embodiment of the present invention, on the one hand, compared with the technical solution of multiple independently arranged contactors 100, the number of contacts can be reduced. While reducing risk points and power loss, the circuit in which the contactor 100 is located can be simplified, the structure of the contactor 100 can be simplified, and the space occupied by the contactor 100 can be reduced, thereby reducing the production cost of the contactor 100 and reducing the difficulty of layout. On the other hand, by driving the rotation of the micro switch 33 by two drive coils, not only can the volume of the first drive coil 31 and the second drive coil 32 be set smaller, which can further improve the space occupied by the contactor 100, but also the stroke of the micro switch 33 can be adjusted by adjusting the distance between the first drive coil 31 and the second drive coil 32, which can improve the applicability of the contactor 100. Moreover, a reasonable stroke of the micro switch 33 can reduce the probability of arcing and adhesion, thereby ensuring the reliability of the contactor 100.

[0061] It should be pointed out that reducing risk points and power loss means that the number of terminals 10 is less than that of the existing technology, which can reduce the high-voltage loss, arcing number and adhesion points caused by the moving contacts, and at the same time reduce the wear caused by the operation of the contactor 100.

[0062] In some embodiments, the distance between the rotation center of the micro switch 33 and any end of the micro switch 33 is smaller than the distance between the contact point between the second terminal 12 and the second conductive section 22 and the rotation center of the micro switch 33, and the distance between the contact point between the third terminal 13 and the second conductive section 22 and the rotation center of the micro switch 33.

[0063] That is, the maximum distance from the rotation center of microswitch 33 to either end is L1; the distance between the contact point between the second terminal 12 and the second conductive segment 22 and the rotation center of microswitch 33 is L2; ​​and the distance between the contact point between the third terminal 13 and the second conductive segment 22 and the rotation center of microswitch 33 is L3, where L1 < L2 and L1 < L3. This allows the conductive member 20 to move the second conductive segment 22 over a greater range than the microswitch 33, thus increasing the travel of the microswitch 33 to meet the electrical clearance requirements of the high-voltage circuit to which the contactor 100 is connected.

[0064] like Figure 2 and Figure 3 As shown, the conductive member 20 and the terminal 10 are arranged opposite to each other in a first direction, and the driving assembly 30 and the conductive member 20 are arranged opposite to each other in a second direction, and the first direction is orthogonal to the second direction.

[0065] Exemplarily, the first direction can be the length direction or width direction in the horizontal direction, and the second direction corresponds to the height direction. In the contactor 100 of the embodiment of the present invention, the terminal 10 and the conductive member 20 are arranged at the same height, and the drive assembly 30 is arranged below or above the terminal 10 and the conductive member 20, rather than the top-down stacking arrangement of the prior art. This can reduce the probability of fracture in the middle of the contactor 100, improve the service life and working stability of the contactor 100, and the contactor 100 is layered in the upper and lower directions to achieve high and low voltage isolation (the upper part is the high voltage conductive part, and the lower part is the low voltage control part).

[0066] Therefore, the arc extinguishing method of the contactor 100 is no longer limited to the combination of inert gas and magnetic blowing arc extinguishing, and can also be achieved by insulating liquid immersion or without setting an arc extinguishing structure. Based on the diversity of arc extinguishing methods, there is no need to insulate the drive coil, which can solve the low-voltage failure problem. Moreover, since there is no need to inject inert gas, there is no need to use ceramic and metal brazing technology to process the contactor 100, which can also simplify the processing technology of the contactor 100, reduce material processes, improve production efficiency, and reduce the processing cost of the contactor 100.

[0067] In some embodiments, during the circuit control of the contactor 100, the second conductive section 22 will collide with the second terminal 12 or the third terminal 13, generating working noise. In order to reduce the working noise of the contactor 100, the conductive part 20 of the present invention is constructed as a flexible part, and a flexible metal material (for example: soft copper composite material, soft silver composite material) can be used to reduce the impact noise and improve the user experience of the contactor 100. At the same time, it can improve the technical problems of large contact resistance and high adhesion probability between the contactor 100 and the terminal 10.

[0068] like Figure 6 、 Figure 7 and Figure 8 As shown, according to some embodiments of the present invention, the micro switch 33 includes: a main body 331 and permanent magnets 332 located at both ends of the main body 331 . The two permanent magnets 332 can selectively be magnetically attracted to the first drive coil 31 or the second drive coil 32 .

[0069] In this way, the permanent magnet 332 can drive the main body 331 of the micro switch 33 to move under the action of the Lorentz force of the first drive coil 31 and the second drive coil 32, and the main body 331 drives the conductive member 20 to move to switch between the first position and the second position, and when the conductive member 20 is in the first position or the second position, the permanent magnets 332 at both ends are magnetically adsorbed on the corresponding drive coils respectively, that is, the closed state of the terminal 10 and the corresponding conductive 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.

[0070] More importantly, the micro switch 33 of the present invention is constructed in a straight line shape, that is, a permanent magnet 332 is provided at each end of the plate-shaped main body 331. By adjusting the distance between the first drive coil 31 and the second drive coil 32, the rotation stroke of the micro switch 33 can be adjusted, and then the rotation stroke of the conductive member 20 can be adjusted to ensure the working reliability of the contactor 100.

[0071] exist Figure 9 and Figure 10 In the specific embodiment shown, in some embodiments, the first drive coil 31 and the second drive coil 32 are arranged in series, and a magnetic conductive sheet 34 is provided at both ends of the side facing each other. The two permanent magnets 332 can selectively magnetically engage with the magnetic conductive sheet 34 of the first drive coil 31 or the magnetic conductive sheet 34 of the second drive coil 32. The magnetic conductive sheet 34 is generally L-shaped, with one end connected to the end of the drive coil. The other ends of the two magnetic conductive sheets 34 at both ends of the same drive coil extend toward each other, making the structure of the drive coil and the micro switch 33 more reasonable, requiring only magnetic attraction with the magnetic conductive sheet 34.

[0072] 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 drive coil 31 and the second drive coil 32 are opposite.

[0073] For example, Figure 10 As shown, the polarity of the permanent magnet 332 located at one end of the main body 331 is N-pole-S-pole, and the polarity of the permanent magnet 332 located at the other end of the main body 331 is S-pole-N-pole, that is, the magnetic poles of the two permanent magnets 332 at one end facing the main body 331 are S-pole and S-pole, respectively, and the magnetic poles at the ends facing away from each other are N-pole and N-pole, respectively; in the energized state, current can flow from the first drive coil 31 to the second drive coil 32. At this time, the polarity of one end of the first drive coil 31 is N-pole and the other end is S-pole, and the magnetic pole of one end of the second drive coil 32 on the same side is S-pole and the magnetic pole of the other end on the same side is N-pole. When the current flows from the second drive coil 32 to the first drive coil 31, the polarities of the two drive coils are exactly opposite.

[0074] In this way, when the conductive member 20 is in the first position, the permanent magnet 332 at one end of the micro switch 33 is attracted to the first drive coil 31, and the permanent magnet 332 at the other end is attracted to the second drive coil 32; when the conductive member 20 is in the second position, the permanent magnet 332 at one end of the micro switch 33 is attracted to the second drive coil 32, and the permanent magnet 332 at the other end is attracted to the first drive coil 31.

[0075] like Figure 12 As shown, in some embodiments, the body 331 is provided with a clamping portion 333, into which the second conducting section 22 extends. Thus, the conducting member 20 can be inserted into the clamping portion 333, and the clamping portions 333 clamp the conducting member 20 on both sides, ensuring that the micro switch 33 can stably and reliably drive the second conducting section 22 to move, thereby improving the operating stability of the contactor 100.

[0076] Of course, the cooperation between the driving coil and the micro switch 33 of the present application is not limited to the above structure, see Figure 11 As shown, in other embodiments, the magnetic poles of the two permanent magnets 332 are located in the thickness direction of the main body 331, and the polarity of the two permanent magnets 332 on the same side is the same. When powered on, the polarity of the first drive coil 31 and the second drive coil 32 on the same side is the same, and the same technical effect as the above embodiment can also be achieved, which will not be repeated here.

[0077] Furthermore, the body 331 is constructed as an insulating member, or the accommodating groove is coated with an insulating layer. This can improve the high-voltage and low-voltage isolation between the high-voltage conducting portion and the low-voltage control portion, prevent high-voltage breakdown from causing low-voltage failure, and improve the operating stability of the contactor 100.

[0078] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the contactor 100 further includes a housing 40, the housing 40 defining an accommodation space, the terminal 10, the conductive member 20, and the drive assembly 30 being disposed within the accommodation space, with the terminal 10 at least partially extending out of the housing 40. Thus, by providing the housing 40, the terminal 10, the conductive member 20, and the drive assembly 30 can be isolated from the outside world, thereby improving operational stability while reducing interference from the outside environment on the first drive coil 31 and the second drive coil 32, thereby improving the control response efficiency of the low-voltage control portion.

[0079] Furthermore, a low-voltage signal terminal 50 is provided outside the housing 40. The low-voltage signal terminal 50 is pluggable and arranged on the housing 40 and is 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 wiring harness outlet, and 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 wiring harness outlet. In other embodiments, the low-voltage signal terminal 50 is fixed to the housing 40 in a plug-in manner, and a corresponding plug interface is provided on the housing 40. The plug interface is electrically connected to the first drive coil 31 or the second drive coil 32, and the plug interface low-voltage signal terminal 50 is plugged in and matched, so that the appearance of the contactor 100 of the present invention is consistent with that of the traditional contactor 100, which facilitates structural design and material switching, and can reduce the R&D cycle and development cost.

[0080] A flexible connection portion 23 is provided between the first conductive section 21 and the second conductive section 22 .

[0081] Specifically, the two ends of the flexible connection part 23 are respectively connected to the first conductive section 21 and the second conductive section 22. During the switching of the second conductive section 22 between the first position and the second position, the flexible connection part 23 bends to adjust the position of the second conductive section 22. The flexible connection part 23 has stronger anti-bending performance, which can prevent the conductive part 20 from breaking during operation, thereby extending the service life of the contactor 100.

[0082] Preferably, the flexible connecting portion 23 , the first conducting section 21 and the second conducting section 22 are made of the same material, that is, a flexible metal material.

[0083] It should be noted that the contactor 100 of the present invention is not limited to the above-mentioned structural form. In other embodiments, by changing the plane where the angular coordinates of the contactor 100 are installed, 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, it can be understood that the contactor 100 also includes a sensor, which is arranged near the first terminal 11 or the second terminal 12 or the third terminal 13 or the conductive member 20, and is used to detect the circuit signal of the first terminal 11 or the second terminal 12 or the third terminal 13 or the conductive member 20 in real time, wherein the circuit signal includes: temperature change, voltage change and current change.

[0085] In this way, by setting a sensor, as the first terminal 11 and the second terminal 12 or the third terminal 13 are connected through the conductive member 20, the current and heat generation of the high-voltage circuit will change, and corresponding temperature changes will occur. The sensor can obtain the change information (temperature change, current change, etc.) during the operation of the high-voltage circuit and transmit it to the corresponding controller in the form of a circuit signal. The controller determines whether the cut-off threshold (temperature threshold, voltage threshold, current threshold) of the high-voltage circuit is reached according to the circuit signal, and when the high-voltage circuit needs to be disconnected, controls other positions of the circuit where the contactor 100 is located to be disconnected (for example, controls other contactors to be disconnected). Not only does it not need to set a fuse to reduce high-voltage loss and reduce costs, but after the control circuit is disconnected, if the electrical equipment using the contactor 100 of the present invention needs to continue working, it can also ensure that the electrical equipment can be on high voltage, which can improve safety.

[0086] It should be pointed out that after the fuse blows, the high-voltage circuit is completely disconnected. However, by setting up a controller and a sensor, the present invention can still supply high voltage electricity to improve safety under extreme conditions, even if the high voltage electricity needs to be disconnected based on the information obtained by the sensor. For example, the contactor 100 of the present invention is used on 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 electricity state can be maintained, and after driving to a safe position or after the dangerous situation is resolved, the other positions of the circuit where the contactor 100 is located can be controlled to be disconnected.

[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, thereby reducing the number of contactors 100 and simplifying the high-voltage circuit to which the high-voltage conductive part is connected.

[0089] like Figure 16 、 Figure 17 and Figure 18As shown, the first connection terminal 11 includes: a first connection terminal 111 and a first interface 112 connected to each other, the second connection terminal 12 includes: a second connection terminal 121 and a second interface 122 connected to each other, and the third connection terminal 13 includes: a third connection terminal 131 and a third interface 132 connected to each other. The first connection terminal 111 is fixed to the first conductive section 21, and the second connection terminal 121 and the third connection terminal 131 can be selectively connected to the second conductive section 22. The first interface 112, the second interface 122 and the third interface 132 can all be constructed in multiple forms.

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

[0091] like Figure 20 As 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 the embodiment of the present invention adopts the above-mentioned contactor 100 , and the technical effects thereof are consistent with those of the above-mentioned contactor 100 , which will not be described in detail here.

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

[0094] The vehicle 1000 according to the embodiment of the present invention adopts the above-mentioned contactor 100 , and the technical effects thereof are consistent with those of the above-mentioned contactor 100 , which will not be described in detail here.

[0095] See also Figure 13-15 As shown, there may be several usage scenarios for the vehicle 1000 of the present invention using the contactor 100 .

[0096] like Figure 13 As shown, in a usage scenario where the in-vehicle discharge socket and the external discharge socket cannot carry a load at the same time, the on-board charger and the DC / DC converter are electrically connected to the first terminal 11 through a wiring harness, the second terminal 12 is electrically connected to the in-vehicle discharge socket, and the third terminal 13 is electrically connected to the external discharge socket. The low-voltage control part controls the first terminal 11 to be conductive with the second terminal 12 or with the third terminal 13, so that the in-vehicle discharge socket or the external discharge socket can be loaded respectively, thereby avoiding the phenomenon of the in-vehicle discharge socket and the external discharge socket being connected to the load at the same time, thereby improving usage safety.

[0097] like Figure 14As shown, in the usage scenario of a DC charging socket charging a battery pack, the charging voltages of DC charging guns equipped with different charging piles are different. Some charging guns can directly charge the battery pack, while 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 boost circuit is set thereon, and the third terminal 13 is directly electrically connected to the battery pack. When charging is performed with a charging gun that requires boosting, the first terminal 11 and the second terminal 12 are connected, and charging is performed after boosting. When charging is performed without boosting, the first terminal 11 and the third terminal 13 are connected through the conductive member 20, which can improve the adaptability of the vehicle 1000, ensure that charging guns of different specifications and sizes can be charged, and reduce unnecessary high-voltage power loss.

[0098] like Figure 15 As shown, for the dual-motor solution of the whole vehicle, when the dual-motor windings are used for DC charging and boosting, in order to improve the service life of the motor, the two motors are replaced with each other for DC charging and boosting. The contactor 100 of the present invention can be used to control the switching between the two motors to avoid overheating of the motor winding of a motor during the boosting process, thereby extending the service life of the motor.
