When the vehicle is in the high-voltage power-on state (i.e., the second contactor K2 and the third contactor K3 are in the on state) in a non-driving scenario, and the power battery is to be DC charged (i.e., fast charged), the low-voltage control components of the fourth contactor K4 and the fifth contactor K5 receive a contactor on signal from the host computer, and the high-voltage contacts of the fourth contactor K4 and the fifth contactor K5 are synchronously switched from the off state to the on state, and the vehicle is in the DC charging (i.e., fast charged) state. When the DC charging of the power battery is completed, the low-voltage control components of the fourth contactor K4 and the fifth contactor K5 receive a contactor off signal from the host computer, and the high-voltage contacts of the fourth contactor K4 and the fifth contactor K5 are synchronously switched from the on state to the off state.

[0129] 2.2. When the vehicle is in the high-voltage power-off state (i.e., the first contactor K1, the second contactor K2, the third contactor K3, the fourth contactor K4, and the fifth contactor K5 are all in the disconnected state), and the power battery is to be DC charged (i.e., fast charged), the third contactor K3, the second contactor K2, and the first contactor K1 are closed in sequence, and then the third contactor K3 is disconnected.

[0130] When the first contactor K1 and the second contactor K2 are both closed and the third contactor K3 is open, the fourth contactor K4 and the fifth contactor K5 begin to execute the action flow in 2.1. After the action flow in 2.1 is completed, if the vehicle needs to switch to the driving state, the second contactor K2 and the third contactor K3 do not need to continue to execute the action. If the vehicle needs to provide high voltage, the second contactor K2 and the third contactor K3 are opened, and the first contactor K1 is connected.

[0131] Scenario 3: When the vehicle needs to travel.

[0132] 3.1 When the vehicle is in the high-voltage power-on state in the non-driving scenario (i.e., the second contactor K2 and the third contactor K3 are in the on state), the fourth contactor K4 and the fifth contactor K5 do not need to perform any action process.

[0133] 3.2 When the vehicle is in the high-voltage power-off state (i.e., the first contactor K1, the second contactor K2, the third contactor K3, the fourth contactor K4 and the fifth contactor K5 are all in the disconnected state), the third contactor K3, the second contactor K2 and the first contactor K1 are closed in sequence, and then the third contactor K3 is disconnected.

[0134] Scenario 4: When the vehicle starting battery (low-voltage power supply battery) needs to be charged.

[0135] 4.1 When the vehicle is in the high-voltage power-on state (i.e., the second and third contactors K2 and K3 are in the on-state), the fourth and fifth contactors K4 and K5 do not need to perform any action procedures. The OBC / DC (onboard power supply) receives signals from the host computer and charges the starting battery (low-voltage power supply).

[0136] When the starting battery (low-voltage power supply) is fully charged, the second contactor K2 and the third contactor K3 are disconnected, and the first contactor K1 is turned on.

[0137] 4.2 When the vehicle is in the high-voltage power-off state (i.e., the first contactor K1, the second contactor K2, the third contactor K3, the fourth contactor K4, and the fifth contactor K5 are all in the disconnected state), the third contactor K3, the second contactor K2, and the first contactor K1 are closed in sequence, and then the third contactor K3 is disconnected.

[0138] When the first contactor K1 and the second contactor K2 are closed and the third contactor K3 is in the open state, the action flow in 4.1 needs to be continued.

[0139] Scenario 5: The vehicle starting battery (low-voltage power supply battery) cannot meet the power supply needs of the low-voltage load.

[0140] 5.1 When the vehicle is in the high-voltage power-on state (i.e., the second contactor K2 and the third contactor K3 are in the on-state), the fourth contactor K4 and the fifth contactor K5 do not need to perform any action procedures. The OBC / DC (on-board power supply) receives signals from the host computer and supplies power to the vehicle's low-voltage loads.

[0141] When the high-power low-voltage load is turned off and the starting battery (low-voltage power supply) can meet the power supply demand of the low-voltage load, the second contactor K2 and the third contactor K3 are disconnected, and the first contactor K1 is turned on.

[0142] 5.2 When the vehicle is in the high-voltage power-off state (i.e., the first contactor K1, the second contactor K2, the third contactor K3, the fourth contactor K4, and the fifth contactor K5 are all in the disconnected state), the third contactor K3, the second contactor K2, and the first contactor K1 are closed in sequence, and then the third contactor K3 is disconnected.

[0143] When the first contactor K1 and the second contactor K2 are closed and the third contactor K3 is in the open state, the action flow in 5.1 needs to be continued.

[0144] Scenario 6: When the vehicle needs to be charged by AC (i.e., slow charging).

[0145] 6.1 When the vehicle is in the high-voltage power-on state (i.e., the second contactor K2 and the third contactor K3 are in the on-state) in a non-driving scenario, the OBC / DC (on-board power supply) receives signals from the host computer to operate, i.e., to charge the power battery.

[0146] When the power battery is fully charged or the vehicle executes the command to end charging, if the vehicle needs to switch to driving state, the second contactor K2 and the third contactor K3 do not need to continue to perform operations; if the vehicle needs to provide high voltage, the second contactor K2 and the third contactor K3 are disconnected, and the first contactor K1 is turned on.

[0147] 6.2 When the vehicle is in the high-voltage power-off state (i.e., the first contactor K1, the second contactor K2, the third contactor K3, the fourth contactor K4, and the fifth contactor K5 are all in the disconnected state), the third contactor K3, the second contactor K2, and the first contactor K1 are closed in sequence, and then the third contactor K3 is disconnected.

[0148] When the first contactor K1 and the second contactor K2 are closed and the third contactor K3 is in the open state, the action flow in 6.1 needs to be continued.

[0149] It can be seen from the description of the working scenario of the distribution unit 2000 in this application that the distribution unit 2000 can meet the charging and discharging needs of the vehicle, and since the first contactor K1, the second contactor K2, the third contactor K3, the pre-charging resistor 9, the fourth contactor K4, and the fifth contactor K5 are all arranged in the outer shell 200, the pre-charging resistor 9 and multiple DC contactors can be integrated. The circuit layout in the distribution unit 2000 is simple, which can reduce the space occupied by multiple contactors and reduce the cost of the distribution unit 2000.

[0150] like Figure 68 As shown, in some embodiments of the present invention, the power distributor 2000 further includes a sixth contactor K6, a seventh contactor K7, and an AC charging interface. The sixth contactor K6 is connected between the positive terminal of the AC charging interface and the positive terminal of the battery terminal interface 203, and the seventh contactor K7 is connected between the negative terminal of the AC charging interface and the negative terminal of the battery terminal interface 203. By providing the sixth contactor K6, the seventh contactor K7, and the AC charging interface, an on-board charger can be connected to the AC charging interface to achieve AC charging.

[0151] In some embodiments of the present invention, the power distributor 2000 further includes: a temperature sensor and a controller, and the temperature sensor is electrically connected to the controller.

[0152] Among them, the controller can be the vehicle's original host computer, and the temperature sensor and the host computer use CAN (Controller Area Network) communication control, so that the original host computer can be used to control the temperature sensor, which is convenient for simplifying the control structure of the temperature sensor and reducing production costs.

[0153] Furthermore, the temperature sensor is used to detect the circuit signal of the first contactor K1, the second contactor K2, the third contactor K3, the fourth contactor K4, the fifth contactor K5 and / or the pre-charging resistor 9, and the controller is used to control the conduction or disconnection of the first contactor K1, the second contactor K2, the third contactor K3, the fourth contactor K4, the fifth contactor K5 and / or the pre-charging resistor 9 according to the circuit signal; wherein the circuit signal includes: temperature change, voltage change and current change, etc., which are not limited here.

[0154] In some examples, the temperature sensor is welded on the first contactor K1, the second contactor K2, the third contactor K3, the fourth contactor K4, the fifth contactor K5 and / or the pre-charging resistor 9, and the temperature sensor is electrically connected to the host computer. As the first contactor K1, the second contactor K2, the third contactor K3, the fourth contactor K4, the fifth contactor K5 and / or the pre-charging resistor 9 are turned on, the current carrying capacity and the heat generation of the high-voltage circuit will change, and the temperature will change accordingly. The temperature sensor can obtain the change information (temperature change, current carrying capacity change, etc.) during the operation of the high-voltage circuit. The temperature sensor is used to detect the temperature of the first contactor K1, the second contactor K2, the third contactor K3, the fourth contactor K4, the fifth contactor K5 and / or the pre-charging resistor 9. The temperature changes of the contactor K3, the fourth contactor K4, the fifth contactor K5 and / or the pre-charging resistor 9 are transmitted to the controller in the form of a circuit signal. The controller determines whether the cut-off threshold of the high-voltage circuit is reached according to the circuit signal, and when the high-voltage circuit needs to be disconnected, the controller controls the first contactor K1, the second contactor K2, the third contactor K3, the fourth contactor K4, the fifth contactor K5 and / or the pre-charging resistor 9 to disconnect the electrical connection. Not only is there no need to set a fuse to reduce high-voltage loss and reduce costs, but after controlling the disconnection of the contactor, if the electrical equipment using the distributor 2000 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.

[0155] It should be pointed out that after the fuse blows, the high-voltage circuit is completely disconnected. However, the present invention sets a controller and a temperature sensor. Even if the high voltage needs to be disconnected based on the information obtained by the temperature sensor, high voltage can still be supplied under extreme conditions to improve safety. For example, the distributor 2000 of the present invention is used in an electric vehicle. When the circuit information indicates that the contactor needs to be disconnected but the vehicle is in a dangerous situation and needs to maintain the working condition, the high-voltage state can be maintained, and after driving to a safe position or after the dangerous situation is resolved, the electrical connection of the first contactor K1, the second contactor K2, the third contactor K3, the fourth contactor K4, the fifth contactor K5 and / or the pre-charge resistor 9 is disconnected.

[0156] In this way, the temperature of the first contactor K1, the second contactor K2, the third contactor K3, the fourth contactor K4, the fifth contactor K5 and / or the pre-charging resistor 9 can be prevented from being too high, causing the distributor 2000 to overheat, which is beneficial to enhancing the safety of the distributor 2000. When the vehicle is in a dangerous situation and needs to maintain the working condition, the high voltage state can be maintained, thereby enhancing the practicality of the distributor 2000.

[0157] Of course, the temperature sensor may also be provided at other locations of the high-voltage circuit in other structural forms to detect the circuit signal of the high-voltage circuit, which is not limited here.

[0158] like Figure 5As shown, according to some embodiments of the present invention, the input end of the first contactor K1 is connected to the output end of the fourth contactor K4 via a first conductive bar 208, and the first conductive bar 208 is also connected to the positive terminal of the electrical control terminal interface 202. Furthermore, the input end of the second contactor K2 is connected to the output end of the fifth contactor K5 via a second conductive bar 209, and the second conductive bar 209 is also connected to the negative terminal of the electrical control terminal interface 202. Furthermore, the second conductive bar 209 includes a first sub-copper bar 2094 and a second sub-copper bar 2095. The first sub-copper bar 2094 is connected between the input end of the second contactor K2 and the negative terminal of the electrical control terminal interface 202, and the second sub-copper bar 2095 is connected between the output end of the fifth contactor K5 and the first sub-copper bar 2094. Furthermore, a fourth conductive bar 2092 is connected between the output end of the first contactor K1 and the positive terminal of the battery terminal interface 203. Furthermore, a fifth conductive bar 2093 is connected between the output end of the second contactor K2 and the positive end of the battery terminal interface 203 .

[0159] In some embodiments of the present invention, Figure 5 As shown, the distributor 2000 also includes: a first inner shell 204, the first inner shell 204 is fixedly arranged in the outer shell 200, the first contactor K1, the second contactor K2, the third contactor K3 and the pre-charging resistor 9 are integrated in the first inner shell 204, the input end and the output end of the first contactor K1 are both arranged on the first inner shell 204, and the input end and the output end of the second contactor K2 are both arranged on the first inner shell 204. Such a setting can integrate the first contactor K1, the second contactor K2, the third contactor K3 and the pre-charging resistor 9, which can make the circuit layout in the distributor 2000 simpler, further reduce the occupied space of multiple contactors, and further reduce the cost of the distributor 2000.

[0160] According to one embodiment of the present invention, Figure 6-Figure 28 As shown, the first contactor K1 and the second contactor K2 both include: a main bonding conductor 3, which is connected to the corresponding input end, and the main bonding conductor 3 is selectively electrically connected to the corresponding output end. It should be noted that the first contactor K1 and the second contactor K2 are respectively provided with a main bonding conductor 3. Taking the first contactor K1 as an example, the main bonding conductor 3 of the first contactor K1 is connected to the input end of the first contactor K1, and the main bonding conductor 3 of the first contactor K1 is selectively electrically connected to the output end of the first contactor K1.

[0161] Furthermore, the third contactor K3 includes a pre-charge bonding conductor 91. The pre-charge bonding conductor 91 and the pre-charge resistor 9 are respectively connected to the input and output of one of the first contactor K1 and the second contactor K2. The pre-charge bonding conductor 91 is selectively electrically connected to the pre-charge resistor 9. Preferably, the pre-charge bonding conductor 91 and the pre-charge resistor 9 are respectively connected to the input and output of the first contactor K1. This configuration ensures that the power distributor 2000 meets the charging and discharging requirements of the vehicle.

[0162] Furthermore, a drive component 4 is provided in the first inner shell 204, and the drive component 4 is used to drive the main bonding conductor 3 to be electrically connected to the corresponding output terminal, and the drive component 4 is also used to drive the pre-charge bonding conductor 91 to be electrically connected to the pre-charge resistor 9. Among them, the drive component 4 is used to drive the main bonding conductor 3 of the first contactor K1 to be connected to the output terminal of the first contactor K1, and the drive component 4 is used to drive the main bonding conductor 3 of the second contactor K2 to be connected to the output terminal of the second contactor K2. The control of the pre-charge bonding conductor 91 and the main bonding conductor 3 can be achieved through the same drive component 4. After the power distributor 2000 of the present application is applied to a vehicle (such as a new energy vehicle), it can meet the charging and discharging requirements of the vehicle (the charging and discharging principle is described below), and multiple contactors can be integrated together. At the same time, the risk of mutual influence between the high-voltage main circuit and the low-voltage control circuit can be avoided, which is conducive to enhancing the safety and practicality of the power distributor 2000.

[0163] Furthermore, the driving component 4 includes: a first fan-shaped portion 411, a second fan-shaped portion 412 and a third fan-shaped portion 413, the main bonding conductor 3 includes a first bonding conductor 3a and a second bonding conductor 3b, the first fan-shaped portion 411 is used to push the first bonding conductor 3a and release the push on the first bonding conductor 3a, the second fan-shaped portion 412 is used to push the second bonding conductor 3b and release the push on the second bonding conductor 3b, and the third fan-shaped portion 413 is used to push the pre-filled bonding conductor 91 and release the push on the pre-filled bonding conductor 91; wherein, when the first fan-shaped portion 411 pushes the first bonding conductor 3a, the first bonding conductor 3a is connected to the corresponding output end, when the second fan-shaped portion 412 pushes the second bonding conductor 3b, the second bonding conductor 3b is connected to the corresponding output end, and when the third fan-shaped portion 413 pushes the pre-filled bonding conductor, the pre-filled bonding conductor 91 is connected to the pre-filled resistor 9.

[0164] In some embodiments of the present invention, the drive assembly 4 further includes: a first power source 42 and a first transmission rod 43. The first power source 42 is connected to the end of the first transmission rod 43 and is used to drive the first transmission rod 43 to rotate. The first fan-shaped portion 411, the second fan-shaped portion 412, and the third fan-shaped portion 413 are all provided on the first transmission rod 43. The first fan-shaped portion 411, the second fan-shaped portion 412, and the third fan-shaped portion 413 all rotate synchronously around a first axis, and the first axis coincides with the axis of the first transmission rod 43. In particular, by driving the first transmission rod 43 to rotate through the first power source 42, the first fan-shaped portion 411, the second fan-shaped portion 412, and the third fan-shaped portion 413 can be driven to rotate simultaneously.

[0165] Furthermore, the first fan-shaped portion 411, the second fan-shaped portion 412, and the third fan-shaped portion 413 push the first bonding conductor 3a, the second bonding conductor 3b, and the pre-charge bonding conductor 91 respectively during the rotation process, and release the push on the first bonding conductor 3a, the second bonding conductor 3b, and the pre-charge bonding conductor 91, thereby making the first bonding conductor 3a and the second bonding conductor 3b conductive with the corresponding output end, and also making the pre-charge bonding conductor 91 conductive with the pre-charge resistor 9.

[0166] In some embodiments of the present invention, the power distributor 2000 further includes: a second inner housing 205, the second inner housing 205 being fixedly disposed within the outer housing 200, the fourth contactor K4 and the fifth contactor K5 being integrated within the second inner housing 205, the input and output ends of the fourth contactor K4 being both disposed on the second inner housing 205, and the input and output ends of the fifth contactor K5 being both disposed on the second inner housing 205. This configuration allows the fourth contactor K4 and the fifth contactor K5 to be integrated into one contactor, thereby simplifying the internal structure of the power distributor 2000.

[0167] Specifically, refer to Figure 7-Figure 28 A contactor according to an embodiment of the present invention is described. The contactor is a DC contactor. The contactor is integrated with at least two terminal groups, each terminal group includes a first terminal 1 (i.e., the input terminal mentioned above) and a second terminal 2 (i.e., the output terminal mentioned above). The contactor is also integrated with a pre-charge resistor 9 and a pre-charge bonding conductor 91, so as to form at least three groups of DC circuits. The contactor integrates three DC contactors together, and the pre-charge resistor 9 of the contactor has discharge capacity.

[0168] like Figure 7-Figure 28As shown, the contactor according to an embodiment of the present invention includes: at least two terminal groups, at least two main bonding conductors 3, a drive component 4, a pre-charge bonding conductor 91 and a pre-charge resistor 9. The number of terminal groups can be flexibly set according to actual usage requirements. Preferably, the terminal groups are set to two groups, and the main bonding conductors 3 are set in a one-to-one correspondence with the terminal groups. That is, one terminal group is correspondingly provided with one main bonding conductor 3, and each main bonding conductor 3 is connected to the corresponding first terminal 1. The pre-charge bonding conductor 91 and the pre-charge resistor 9 are respectively connected to the first terminal 1 and the second terminal 2 of a terminal group. For example, the pre-charge bonding conductor 91 is connected to the first terminal 1, and the pre-charge resistor 9 is connected to the second terminal 2.

[0169] It should be noted that one first wiring terminal 1 may correspond to one second wiring terminal 2 , and one first wiring terminal 1 and one second wiring terminal 2 may form a direct current circuit.

[0170] The main bonding conductor 3 is made of a conductive material, such as iron or composite metals such as soft copper (silver), so that the conductivity of the main bonding conductor 3 can be improved while reducing the weight and volume of the main bonding conductor 3, so that the main bonding conductor 3 can have a larger current carrying capacity, thereby improving the conductivity of the contactor.

[0171] At the same time, the use of composite materials such as soft copper (silver) in the main bonding conductor 3 makes the main bonding conductor 3 formed into a soft material, which solves the rigid contact that occurs when the main bonding conductor 3 contacts the second terminal 2, effectively reduces the noise generated during contact, and further enhances the practicality of the contactor.

[0172] The pre-charging resistor 9 is connected to the second terminal 2, and the main bonding conductor 3 is connected to the first terminal 1. Furthermore, the pre-charging resistor 9 is connected to a second connection terminal 92, and the pre-charging bonding conductor 91 is adapted to be bonded to the second connection terminal 92.

[0173] Among them, the drive component 4 and the host computer use CAN (controller area network) communication control, and are used for control according to CAN signals. The drive component 4 is used to drive the main bonding conductor 3 to be electrically connected to the corresponding second terminal 2, and the drive component 4 is also used to drive the pre-charge bonding conductor 91 to be electrically connected to the pre-charge resistor 9. Furthermore, the pre-charge bonding conductor 91 is electrically connected to the second connection terminal 92. The control of the pre-charge bonding conductor 91 and the main bonding conductor 3 can be achieved through the same drive component 4. After the contactor of the present application is applied to a vehicle (such as a new energy vehicle), it can meet the charging and discharging requirements of the vehicle (the charging and discharging principle is described below), and multiple contactors can be integrated together. At the same time, the risk of mutual influence between the high-voltage main circuit and the low-voltage control circuit can be avoided, which is beneficial to enhancing the safety and practicality of the contactor.

[0174] At the same time, the contactor can also include a temperature sensor, which is welded on the main bonding conductor 3 and electrically connected to the host computer. The temperature sensor is used to detect the temperature change of the main bonding conductor 3 and transmit the real-time temperature value of the main bonding conductor 3 to the host computer. The host computer then determines whether the temperature meets the threshold temperature for disconnecting the first terminal 1 and the second terminal 2. If the temperature reaches the threshold temperature, the first terminal 1 and the second terminal 2 are controlled to be disconnected, thereby preventing the temperature of the main bonding conductor 3 from being too high and causing the contactor to overheat, which is beneficial to enhancing the safety of the contactor. Of course, the temperature sensor can also be set at other positions in the DC circuit to detect the temperature of the DC circuit, which is not limited here.

[0175] Therefore, the contactor of the present application can integrate at least three DC contactors and a pre-charging resistor 9. The contactor has a pre-charging circuit that can meet the charging and discharging needs of the vehicle. Moreover, the pre-charging bonding conductor 91 and the main bonding conductor 3 can be controlled through the same drive component 4. In addition, the contactor can avoid the risk of mutual influence between the high-voltage main circuit and the low-voltage control circuit, which is beneficial to enhancing the safety and practicality of the contactor.

[0176] In some embodiments of the present invention, Figure 8 As shown, there are two terminal groups, and the first terminal 1 of one terminal group is the positive input terminal 11 and the second terminal 2 is the positive output terminal 21, and the first terminal 1 of the other terminal group is the negative input terminal 12 and the second terminal 2 is the negative output terminal 22, wherein the positive input terminal 11 and the positive output terminal 21 constitute a set of DC circuits, and the main connecting conductor 3 connected to the positive input terminal 11 can selectively control the conduction or disconnection of the positive input terminal 11 and the positive output terminal 21, and the negative input terminal 12 and the negative output terminal 22 constitute another set of DC circuits, and the main connecting conductor 3 connected to the negative input terminal 12 can selectively control the conduction or disconnection of the negative input terminal 12 and the negative output terminal 22.

[0177] Furthermore, if Figure 9 As shown, the main bonding conductor 3 may include a first bonding conductor 3 a and a second bonding conductor 3 b .

[0178] The first bonding conductor 3a is connected to the positive input terminal 11 and is used to selectively connect or disconnect the positive output terminal 21. The second bonding conductor 3b is connected to the negative input terminal 12 and is used to selectively connect or disconnect the negative output terminal 22. In other words, the first bonding conductor 3a can selectively control the connection or disconnection between the positive input terminal 11 and the positive output terminal 21, while the second bonding conductor 3b can selectively control the connection or disconnection between the negative input terminal 12 and the negative output terminal 22. Thus, the first bonding conductor 3a and the second bonding conductor 3b can selectively control the connection or disconnection of the two DC circuits.

[0179] In some embodiments of the present invention, the driving component 4 is used to drive the pre-charge bonding conductor 91 and the second connection end 92, the second bonding conductor 3b and the negative output terminal 22, and the first bonding conductor 3a and the positive output terminal 21 to selectively conduct in sequence. Specifically, after the driving component 4 receives the control signal from the host computer, the driving component 4 starts to work, such as Figure 19 As shown, the driving component 4 first drives the pre-filling joint conductor 91 to conduct with the second connection end 92, and the pre-filling circuit becomes conductive, as shown in FIG. Figure 22 As shown, the driving component 4 then drives the second bonding conductor 3b to conduct with the negative output terminal 22, which corresponds to the vehicle being in a pre-charge state of high voltage electricity. Figure 25 As shown, the driving component 4 then drives the first bonding conductor 3a to conduct with the positive output terminal 21, so that the main positive circuit of the contactor is in a conducting state, as shown in FIG. Figure 27 As shown, the driving component 4 then drives the pre-charge connection conductor 91 to disconnect from the second connection end 92, and the pre-charge circuit is in the open state. At this time, the entire vehicle is in the normal high-voltage power-keeping state. The contactor maintains this state for the entire time when the vehicle needs high-voltage power. When the vehicle needs to reduce high-voltage power, as shown in FIG. Figure 28 As shown, the driving component 4 drives the first bonding conductor 3a to be disconnected from the positive output terminal 21, and then the driving component 4 drives the first bonding conductor 3a to be disconnected from the positive output terminal 21, as shown in FIG. Figure 18 As shown, the main negative circuit, main positive circuit, and pre-charge circuit are all in the open state. At this time, the entire vehicle is in a low-voltage state. The contactor remains in this state all the time when the vehicle does not need high voltage. Therefore, this configuration allows the contactor to meet the charging and discharging needs of the vehicle and can simplify the contactor structure.

[0180] In some embodiments of the present invention, Figure 13As shown, the drive assembly 4 includes a fan-shaped drive unit 41, which is configured to rotate about a first axis. During rotation, the fan-shaped drive unit 41 pushes and releases the push of the multiple main bonding conductors 3 and the pre-filling bonding conductor 91. When the fan-shaped drive unit 41 pushes the multiple main bonding conductors 3, the multiple main bonding conductors 3 are connected to the corresponding second terminals 2. When the fan-shaped drive unit 41 pushes the pre-filling bonding conductor 91, the pre-filling bonding conductor 91 is connected to the pre-filling resistor 9. Furthermore, the fan-shaped drive unit 41 drives the pre-charge bonding conductor 91 and the second connection end 92, the first bonding conductor 3a and the positive output terminal 21, and the second bonding conductor 3b and the negative output terminal 22 to conduct during the rotation process. That is to say, when the fan-shaped drive unit 41 rotates, the fan-shaped drive unit 41 can drive the pre-charge bonding conductor 91 and the second connection end 92 to conduct, the fan-shaped drive unit 41 can also drive the second bonding conductor 3b and the negative output terminal 22 to conduct, and the fan-shaped drive unit 41 can also drive the first bonding conductor 3a and the positive output terminal 21 to conduct. It should be noted that the fan-shaped drive unit 41 first drives the pre-charge bonding conductor 91 and the second connection end 92 to conduct, and then the fan-shaped drive unit 41 drives the second bonding conductor 3b and the negative output terminal 22 to conduct. The positive output terminal 22 is turned on, and then the fan-shaped driving unit 41 drives the first bonding conductor 3a to turn on the positive output terminal 21. Then, when the fan-shaped driving unit 41 is separated from the pre-charge bonding conductor 91, the pre-charge bonding conductor 91 and the second connection end 92 are disconnected. Then, when the fan-shaped driving unit 41 is separated from the second bonding conductor 3b, the second bonding conductor 3b is disconnected from the negative output terminal 22. Then, when the fan-shaped driving unit 41 is separated from the first bonding conductor 3a, the first bonding conductor 3a is disconnected from the positive output terminal 21, thereby achieving the technical effect of driving the pre-charge bonding conductor 91 and the second connection end 92, the first bonding conductor 3a and the positive output terminal 21, and the second bonding conductor 3b and the negative output terminal 22 to be selectively turned on or off in sequence.

[0181] Specifically, if Figure 10 As shown, the fan-shaped drive portion 41 can be constructed as a fan-shaped sheet structure, and the fan-shaped drive portion 41 can rotate around the first axis, wherein the fan-shaped drive portion 41 is used to drive the main bonding conductor 3 and its corresponding second connection terminal 2 to conduct when rotating, and the fan-shaped drive portion 41 is also used to drive the pre-filled bonding conductor 91 and the second connection terminal 92 to conduct.

[0182] It should be noted that the fan-shaped drive unit 41 can drive the main bonding conductor 3 to engage with its corresponding second terminal 2, and can also drive the pre-charge bonding conductor 91 to engage with the pre-charge resistor 9. When the fan-shaped drive unit 41 does not drive the main bonding conductor 3 and the pre-charge bonding conductor 91, the main bonding conductor 3 and the pre-charge bonding conductor 91 can rely on their own elastic reset to separate the main bonding conductor 3 from its corresponding second terminal 2, and the pre-charge bonding conductor 91 from the pre-charge resistor 9. However, the present invention is not limited to this. A reset drive structure can also be provided in the contactor to drive the main bonding conductor 3 to disconnect from its corresponding second terminal 2, and to drive the pre-charge bonding conductor 91 to disconnect from the pre-charge resistor 9. The reset drive node can be provided as a torsion spring.

[0183] Preferably, if Figure 16 As shown, the main bonding conductor 3 is connected to the first terminal 1 through a metal conductor 10, and the metal conductor 10 is arranged between the first terminal 1 and the main bonding conductor 3. By arranging the metal conductor 10, it can play a conductive role between the first terminal 1 and the main bonding conductor 3, and one end of the main bonding conductor 3 can be fitted and connected to the metal conductor 10, thereby ensuring the conductivity between the first terminal 1 and the main bonding conductor 3, and the fan-shaped drive part 41 can make the main bonding conductor 3 and the second terminal 2 conductive when rotating, and then the first terminal 1 and the second terminal 2 can be conductive through the rotation of the fan-shaped drive part 41, thereby facilitating the control of the working state of the contactor to meet the different DC charging needs of users.

[0184] Furthermore, if Figure 13 As shown, the fan-shaped driving portion 41 includes a first fan-shaped portion 411, a second fan-shaped portion 412 and a third fan-shaped portion 413 spaced apart and distributed along the axial direction of the first axis, the main bonding conductor 3 includes a first bonding conductor 3a and a second bonding conductor 3b, the first fan-shaped portion 411 is used to push the first bonding conductor 3a and release the push on the first bonding conductor 3a, the second fan-shaped portion 412 is used to push the second bonding conductor 3b and release the push on the second bonding conductor 3b, and the third fan-shaped portion 413 is used to push the pre-filled bonding conductor 91 and release the push on the pre-filled bonding conductor 91.

[0185] Thus, the first fan-shaped portion 411 is used to push the first bonding conductor 3a so that the first bonding conductor 3a can control the conduction of the positive input terminal 11 and the positive output terminal 21, the second fan-shaped portion 412 is used to push the second bonding conductor 3b so that the second bonding conductor 3b can control the conduction of the negative input terminal 12 and the negative output terminal 22, and the third fan-shaped portion 413 is used to push the pre-charge bonding conductor 91 so that the pre-charge bonding conductor 91 and the pre-charge resistor 9 are conductive, that is, the first fan-shaped portion 411 and the second fan-shaped portion 412 correspond one-to-one to the first bonding conductor 3a and the second bonding conductor 3b, and the third fan-shaped portion 413 corresponds to the pre-charge bonding conductor 91, so as to facilitate the separate control of the first bonding conductor 3a, the second bonding conductor 3b, and the pre-charge bonding conductor 91 through the first fan-shaped portion 411, the second fan-shaped portion 412, and the third fan-shaped portion 413, thereby facilitating the separate conduction of one group of DC circuits.

[0186] It should be noted that when at least two terminal groups are integrated in the contactor, the number of bonding conductors and the number of fan-shaped portions should be the same as the number of first terminals 1, thereby achieving control of multiple groups of first terminals 1 and second terminals 2.

[0187] In some embodiments of the present invention, the first sector 411, the second sector 412, and the third sector 413 rotate synchronously around the first axis, that is, the first sector 411, the second sector 412, and the third sector 413 rotate simultaneously. Further, the first sector 411, the second sector 412, and the third sector 413 each include a rotating front side and a rotating rear side. It should be noted that the rotating front side means that the sector has a front side and a rear side along the rotation direction of the sector, and the front side of the sector along the rotation direction of the sector is the rotating front side, and the rear side is the rotating rear side.

[0188] During the rotation of the first sector-shaped portion 411, after the front side of the first sector-shaped portion 411 contacts the first bonding conductor 3a and before the rear side of the first sector-shaped portion 411 contacts the first bonding conductor 3a, the first sector-shaped portion 411 pushes the first bonding conductor 3a, thereby bonding the first bonding conductor 3a to its corresponding second terminal 2. It should be noted that after the rear side of the first sector-shaped portion 411 contacts the first bonding conductor 3a and before the front side of the first sector-shaped portion 411 contacts the first bonding conductor 3a, the first sector-shaped portion 411 releases its push on the first bonding conductor 3a.

[0189] During the rotation of the second sector-shaped portion 412, after the front side of the second sector-shaped portion 412 contacts the second bonding conductor 3b and before the rear side of the second sector-shaped portion 412 contacts the second bonding conductor 3b, the second sector-shaped portion 412 pushes the second bonding conductor 3b, thereby bonding the second bonding conductor 3b to its corresponding second terminal 2. It should be noted that after the rear side of the second sector-shaped portion 412 contacts the second bonding conductor 3b and before the front side of the second sector-shaped portion 412 contacts the second bonding conductor 3b, the second sector-shaped portion 412 releases its push on the second bonding conductor 3b.

[0190] During the rotation of the third sector-shaped portion 413, after the front side of the third sector-shaped portion 413 contacts the pre-fill bonding conductor 91 and before the rear side of the third sector-shaped portion 413 contacts the pre-fill bonding conductor 91, the third sector-shaped portion 413 pushes the pre-fill bonding conductor 91, thereby bonding the pre-fill bonding conductor 91 to the pre-fill resistor 9. It should be noted that after the rear side of the third sector-shaped portion 413 contacts the pre-fill bonding conductor 91 and before the front side of the third sector-shaped portion 413 contacts the pre-fill bonding conductor 91, the third sector-shaped portion 413 releases its push on the pre-fill bonding conductor 91.

[0191] In some embodiments of the present invention, the pre-charge bonding conductor 91 is connected to the first bonding conductor 3a, and the pre-charge resistor 9 is connected to the second terminal 2 of the terminal group corresponding to the first bonding conductor 3a. Along the first axis, the projection of the rotational front side of the third sector-shaped portion 413 and the projection of the rotational front side of the second sector-shaped portion 412, as well as the projection of the rotational front side of the first sector-shaped portion 411 and the projection of the rotational front side of the second sector-shaped portion 412, both form an included angle. This arrangement enables the third sector-shaped portion 413 to first push the pre-charge bonding conductor 91 into engagement with the pre-charge resistor 9, then the second sector-shaped portion 412 to push the second bonding conductor 3b into engagement with the negative output terminal 22, and finally the third sector-shaped portion 413 to push the first bonding conductor 3a into engagement with the positive output terminal 21, thereby achieving a time difference between contactor opening and closing. It should be noted that the pre-charging resistor 9 is connected in parallel with the first bonding conductor 3a, and the connection order of the contactor is that the pre-charging bonding conductor 91 is connected to the pre-charging resistor 9, then the second bonding conductor 3b is connected to the negative output terminal 22, and then the first bonding conductor 3a is connected to the positive output terminal 21.

[0192] Furthermore, along the first axis direction, the angle between the projection of the rotating front side of the first sector portion 411 and the projection of the rotating front side of the second sector portion 412 is A, satisfying the relationship: 60°≤A≤70°, preferably, A is 65°, the angle between the projection of the rotating front side of the second sector portion 412 and the projection of the rotating front side of the third sector portion 413 is B, satisfying the relationship: 20°≤B≤30°, preferably, B is 25°, by setting A to 65° and B to 25°, when the first sector portion 411, the second sector portion 412 and the third sector portion 413 rotate synchronously, it is ensured that the three contactors are opened with a time difference, thereby meeting the charging and discharging needs of the vehicle.

[0193] In some embodiments of the present invention, along the direction of the first axis, there is an angle between the projection of the front side of the second fan-shaped portion 412 and the projection of the rear side of the third fan-shaped portion 413, between the projection of the rear side of the third fan-shaped portion 413 and the projection of the rear side of the first fan-shaped portion 411, and between the projection of the rear side of the first fan-shaped portion 411 and the projection of the rear side of the second fan-shaped portion 412. This arrangement enables the third fan-shaped portion 413 to first release the pre-filled bonding conductor 91, then the second fan-shaped portion 412 to release the second bonding conductor 3b, and then the third fan-shaped portion 413 to release the first bonding conductor 3a.

[0194] In some embodiments of the present invention, Figure 13 As shown, the drive assembly 4 may further include: a first power source 42 and a first transmission rod 43, wherein the output end of the first power source 42 is connected to the end of the first transmission rod 43, and the fan-shaped drive portion 41 is provided on the first transmission rod 43. It can also be understood that the first fan-shaped portion 411, the second fan-shaped portion 412 and the third fan-shaped portion 413 are all provided on the first transmission rod 43 and are spaced apart along the axial direction of the first transmission rod 43, and the first axis coincides with the axis of the first transmission rod 43. The first power source 42 is electrically connected to the host computer, and the first power source 42 can be constructed as an electric motor, so that the speed and direction of the electric motor can be controlled by the host computer. It should be noted that the first fan-shaped portion 411, the second fan-shaped portion 412 and the third fan-shaped portion 413 are distributed on the first transmission rod 43 in a circular manner at a certain angle.

[0195] The first transmission rod 43 rotates in a clockwise direction, and the first transmission rod 43 can rotate at a uniform speed or at a non-uniform speed.

[0196] like Figure 13As shown, the output end of the first power source 42 is connected to the end of the first transmission rod 43, and the other end of the first transmission rod 43 extends in a direction away from the first power source 42. The first axis coincides with the axis of the first transmission rod 43 to ensure that the first transmission rod 43 can rotate along the first axis under the action of the first power source 42, thereby facilitating the first power source 42 to provide driving force for the first transmission rod 43 and increase the rotation speed of the driving rod.

[0197] Furthermore, if Figure 13 As shown, the second fan-shaped portion 412, the first fan-shaped portion 411, and the third fan-shaped portion 413 are all arranged on the first transmission rod 43 and are distributed in sequence along the axial direction of the first transmission rod 43, so as to facilitate the first fan-shaped portion 411 to control the first bonding conductor 3a to be conductive with the positive output terminal 21, facilitate the second fan-shaped portion 412 to control the second bonding conductor 3b to be conductive with the negative output terminal 22, and facilitate the third fan-shaped portion 413 to control the pre-charge bonding conductor 91 to be conductive with the pre-charge resistor 9.

[0198] In some embodiments of the present invention, Figure 15 and Figure 16 As shown, the main bonding conductor 3 may include a fixing portion 31 and a bonding portion 33, the fixing portion 31 and the bonding portion 33 are connected, the fixing portion 31 is fixedly connected to the corresponding first terminal 1, and the driving component 4 is suitable for driving (pushing) the bonding portion 33 to drive (push) the bonding portion 33 to engage with the corresponding second terminal 2.

[0199] Furthermore, the main bonding conductor 3 may further include a weakened portion 32, through which the fixed portion 31 and the joint portion 33 are connected. It should be noted that the first bonding conductor 3a and the second bonding conductor 3b have the same structure, each including a fixed portion 31, a weakened portion 32, and a joint portion 33. The fixed portion 31, the weakened portion 32, and the joint portion 33 are sequentially connected, and the fixed portion 31, the weakened portion 32, and the joint portion 33 may be an integrally molded structure. The fixed portion 31 and the joint portion 33 are connected via the weakened portion 32. The fixed portion 31 is fixedly connected to the first terminal 1, and the driving assembly 4 is adapted to push the joint portion 33 to engage with the second terminal 2.

[0200] Specifically, the end of the main bonding conductor 3 close to the first terminal 1 is the fixed portion 31, and the end of the main bonding conductor 3 away from the first terminal 1 is the joint portion 33. The fixed portion 31 and the joint portion 33 are connected by a weakening portion 32, that is, the weakening portion 32 is arranged between the fixed portion 31 and the joint portion 33, and the fixed portion 31 is fixedly connected to the metal conductor 10 of the first terminal 1 so as to ensure the connection stability and conductivity between the first terminal 1 and the fixed portion 31, and the fan-shaped driving portion 41 is suitable for pressing against the joint portion 33 to push the joint portion 33 to engage with the second terminal 2.

[0201] Understandably, the reference Figure 13 and Figure 15 When it is necessary to control the conduction between the first terminal 1 and the second terminal 2, the first power source 42 generates a driving force, the first transmission rod 43 rotates under the action of the driving force, and the first transmission rod 43 drives the fan-shaped driving part 41 to rotate. When the end of the fan-shaped driving part 41 away from the first transmission rod 43 contacts the joint 33, the end of the fan-shaped driving part 41 away from the first transmission rod 43 will squeeze the joint 33 to move toward the second terminal 2, thereby causing the joint 33 to engage with the second terminal 2, thereby causing the first terminal 1 and the second terminal 2 to be conductive.

[0202] When the first terminal 1 and the second terminal 2 need to be disconnected, refer to Figure 18 The first power source 42 generates a driving force, the first transmission rod 43 rotates under the action of the driving force, and the first transmission rod 43 drives the fan-shaped driving part 41 to rotate. When the end of the fan-shaped driving part 41 away from the first transmission rod 43 does not contact the joint 33, the end of the fan-shaped driving part 41 away from the first transmission rod 43 will not squeeze the joint 33. At this time, the joint 33 will automatically restore to its initial position, that is, the joint 33 is not engaged with the second terminal 2, thereby disconnecting the first terminal 1 from the second terminal 2.

[0203] For example, when it is necessary to control the conduction of the positive input terminal 11 and the positive output terminal 21, the first power source 42 generates a driving force, the first transmission rod 43 rotates under the action of the driving force, and the first transmission rod 43 drives the first fan-shaped portion 411 to rotate. When the end of the first fan-shaped portion 411 away from the first transmission rod 43 contacts the joint 333 of the first bonding conductor 3a, the end of the first fan-shaped portion 411 away from the first transmission rod 43 will squeeze the joint 33 with the first bonding conductor 3a toward the direction of the positive output terminal 21, thereby making the joint 33 engage with the positive output terminal 21, so that the first terminal 1 and the second terminal 2 are conductive.

[0204] When it is necessary to control the positive input terminal 11 and the positive output terminal 21 to be disconnected, the first power source 42 generates a driving force, the first transmission rod 43 rotates under the action of the driving force, and the first transmission rod 43 drives the first fan-shaped portion 411 to rotate. When the end of the first fan-shaped portion 411 away from the first transmission rod 43 does not contact the joint 33 of the first bonding conductor 3a, the end of the first fan-shaped portion 411 away from the first transmission rod 43 will not squeeze the joint 33. At this time, the joint 33 of the first bonding conductor 3a will automatically restore to its initial position, that is, the joint 33 is not engaged with the second terminal 2, thereby disconnecting the positive input terminal 11 and the positive output terminal 21.

[0205] The connection or disconnection between the negative input terminal 12 and the negative output terminal 22 proceeds in the same manner as the connection or disconnection between the positive input terminal 11 and the positive output terminal 21, and is performed synchronously, which will not be further described herein. Furthermore, the connection or disconnection between the pre-charge bonding conductor 91 and the second connection terminal 92 proceeds in the same manner as the connection or disconnection between the positive input terminal 11 and the positive output terminal 21, and is performed synchronously, which will not be further described herein. Furthermore, all three share a common first power source 42 and a common first transmission rod 43. Thus, the same first power source 42 enables connection between the two sets of first terminals 1 and second terminals 2, as well as connection between the pre-charge bonding conductor 91 and the second connection terminal 92, thereby reducing the number of contact points of the contactor, reducing risk points, and enhancing the safety and practicality of the contactor.

[0206] In some embodiments of the present invention, the pre-filled bonding conductor 91 has the same structure as the main bonding conductor 3. Furthermore, the structure of the pre-filled bonding conductor 91 is the same as that of the main bonding conductor 3, that is, the pre-filled bonding conductor 91 includes a fixing portion 31, a weakened portion 32 and a bonding portion 33. When it is necessary to control the conduction between the pre-filled bonding conductor 91 and the second connection end 92, the first power source 42 generates a driving force, and the first transmission rod 43 rotates under the action of the driving force, and the first transmission rod 43 drives the third fan-shaped portion 413 to rotate. When the end of the third fan-shaped portion 413 away from the first transmission rod 43 contacts the bonding portion 33 of the pre-filled bonding conductor 91, the end of the third fan-shaped portion 413 away from the first transmission rod 43 will squeeze the bonding portion 33 of the pre-filled bonding conductor 91 toward the second connection end 92, thereby causing the bonding portion 33 of the pre-filled bonding conductor 91 to engage with the second connection end 92, thereby causing the pre-filled bonding conductor 91 and the second connection end 92 to conduct.

[0207] When it is necessary to control the pre-filled joint conductor 91 and the second connection terminal 92 to be disconnected, refer to Figure 18 The first power source 42 generates a driving force, and the first transmission rod 43 rotates under the action of the driving force, and the first transmission rod 43 drives the third fan-shaped portion 413 to rotate. When the end of the third fan-shaped portion 413 away from the first transmission rod 43 does not contact the joint 33 of the pre-filled bonding conductor 91, the end of the third fan-shaped portion 413 away from the first transmission rod 43 will not squeeze the joint 33 of the pre-filled bonding conductor 91. At this time, the joint 33 of the pre-filled bonding conductor 91 will automatically restore to its initial position, that is, the joint 33 of the pre-filled bonding conductor 91 is not engaged with the second connection end 92, thereby disconnecting the pre-filled bonding conductor 91 and the second connection end 92.

[0208] In some embodiments of the present invention, Figure 16As shown, the weakened portion 32 is constructed as an arc segment, one end of which is connected to the fixing portion 31 and the other end is connected to the connecting portion 33. The weakened portion 32 is recessed toward the second terminal 2 to form a weakened cavity 321 within the weakened portion 32. The provision of the weakened cavity 321 facilitates reducing the squeezing force of the sector-shaped driving portion 41 on the connecting member when the sector-shaped driving portion 41 squeezes the connecting member to connect the connecting member to the second terminal 2, thereby reducing the consumption of the first power source 42, thereby reducing energy consumption and production costs. At the same time, when the connecting member is not connected to the second terminal 2, it facilitates the connecting member to quickly return to its initial position, thereby increasing the speed of connecting or disconnecting the first terminal 1 and the second terminal 2, and improving the working efficiency of the contactor.

[0209] In some embodiments of the present invention, Figure 7 As shown, the contactor may also include: a shell 5 (i.e., a first inner shell 204), an installation space is formed inside the shell 5, the drive component 4, the main bonding conductor 3, the pre-charging resistor 9, and the pre-charging bonding conductor 91 are all arranged on the shell 5, and the first terminal 1 and the second terminal 2 are both arranged on the shell 5, so that the drive component 4, the bonding conductor 3, the pre-charging resistor 9, and the pre-charging bonding conductor 91 do not occupy the external installation space, thereby improving the space utilization rate inside the contactor and facilitating the miniaturization design of the contactor. It should be noted that the shell 5 is made of insulating material, that is, the shell 5 can prevent the leakage problem generated by the contactor, thereby enhancing the safety of the contactor.

[0210] Furthermore, if Figure 7 As shown, the shell 5 includes an upper cover 51, and the first terminal 1 and the second terminal 2 are both arranged on the peripheral wall of the shell 5. Preferably, the first terminal 1 and the second terminal 2 are both arranged on the upper cover 51 of the shell 5 and are spaced apart, which facilitates the separate processing of the first terminal 1 and the second terminal 2 and reduces the processing difficulty.

[0211] At the same time, if Figure 7 As shown, an insulating partition 6 is provided on the outer peripheral wall of the housing 5 between the first terminal 1 and the second terminal 2. Preferably, the insulating partition 6 is provided on the upper cover 51 of the housing 5, and the insulating partition 6 extends along its width direction in a direction away from the upper cover 51. The insulating partition 6 and the upper cover 51 can be an integrally formed structure, which facilitates simultaneous processing and molding of the two, reduces production efficiency, and facilitates separating the first terminal 1 and the second terminal 2 by the insulating partition 6. It can be understood that the insulating partition 6 is made of insulating material, which can avoid the problem of electric shock adhesion between the first terminal 1 and the second terminal 2 when the electronic component is connected to the first terminal 1 and the second terminal 2, thereby enhancing the safety of the electrical connection between the first terminal 1 and the second terminal 2, and further enhancing the safety and practicality of the contactor.

[0212] It should be noted that if Figure 7 As shown, a low-voltage signal line 8 is also provided on the side wall of the housing 5. The low-voltage signal line 8 runs through the housing 5, and one end of the low-voltage signal line 8 extends into the housing 5 to connect to the drive assembly 4 in the contactor, and the other end of the low-voltage signal line 8 extends outside the housing 5 to connect to the control module. Thus, the control module and the drive assembly 4 can be connected via the low-voltage signal line 8, such as the low-voltage signal line 8 is electrically connected to the first power source 42, so as to facilitate the control of the first power source 42 through the control module, thereby achieving control of the drive assembly 4, adjusting the working state of the contactor, and facilitating meeting the user's different charging needs for the vehicle, thereby improving the user experience. However, the present invention is not limited to this. A connector can be provided on the side wall of the housing 5, and the connector replaces the low-voltage signal line 8 of the above embodiment.

[0213] In some embodiments of the present invention, Figure 7 As shown, the housing 5 may be provided with a fixing support 7 having a mounting hole 71. The housing 5 is used to mount the contactor on other components through the mounting hole 71. It should be noted that the housing 5 has a polygonal cross-section. For example, the cross-section of the housing 5 may be a quadrilateral, or the cross-section of the housing 5 may be a hexagon. Of course, in some examples, the cross-section of the housing 5 may also be a circle, etc., so that the shape of the housing 5 can be flexibly designed according to the actual structure of the contactor.

[0214] In some embodiments of the present invention, the contactor may further include: a temperature sensor and a controller (i.e., a host computer), the temperature sensor is electrically connected to the controller, and the temperature sensor is used to detect the circuit signals of the first terminal 1, the second terminal 2, the main bonding conductor 3 and / or the pre-filled bonding conductor 91, and the controller is used to control the main bonding conductor 3 to fit with the second terminal 2 and / or the pre-filled bonding conductor 91 to fit with the second terminal 2 according to the circuit signal.

[0215] Among them, the controller can be the vehicle's original host computer, and the temperature sensor and the host computer use CAN (Controller Area Network) communication control, so that the original host computer can be used to control the temperature sensor, which is convenient for simplifying the control structure of the temperature sensor and reducing production costs.

[0216] Furthermore, the temperature sensor is used to detect circuit signals of the first terminal 1, the second terminal 2, the main bonding conductor 3, and / or the pre-charge bonding conductor 91. The controller is used to control the main bonding conductor 3 to be attached to or separated from the second terminal 2 based on the circuit signals. Preferably, the circuit signal includes a temperature signal or an on / off signal of the main bonding conductor 3, which is not limited here.

[0217] In some examples, the temperature sensor is welded on the main bonding conductor 3, and the temperature sensor is electrically connected to the upper computer. As the main bonding conductor 3 connects the first terminal 1 with the second terminal 2, and / or the pre-charge bonding conductor 91 with the pre-charge resistor 9, the current carrying capacity and the 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 carrying capacity change, etc.) during the operation of the high-voltage circuit. The temperature sensor is used to detect the temperature change of the main bonding conductor 3 and / or the pre-charge bonding conductor 91, and transmit it to the controller in the form of a circuit signal. The controller determines whether the cut-off threshold of the high-voltage circuit is reached based on the circuit signal, and when the high-voltage circuit needs to be disconnected, the controller controls the drive component 4 to release the electrical connection between the main bonding conductor 3 and the second terminal 2. Not only does it not need to set a fuse to reduce high-voltage loss and reduce costs, but after the control disconnects the contactor, if the electrical equipment using the contactor 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.

[0218] 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 power under extreme conditions to improve safety, even if the high voltage power needs to be disconnected based on the information obtained by the sensor. For example, the contactor of the present invention is used in an electric vehicle. When the circuit information indicates that the contactor needs to be disconnected but the vehicle is in a dangerous situation and needs to maintain the working condition, the high-voltage power state can be maintained, and after driving to a safe position or after the dangerous situation is resolved, the electrical connection between the main connecting conductor 3 and the second terminal 2 can be disconnected.

[0219] In this way, the temperature of the main bonding conductor 3 can be prevented from being too high, which causes the contactor to overheat, thereby enhancing the safety of the contactor. When the vehicle is in a dangerous situation and needs to maintain the working condition, the high voltage state can be maintained, thereby enhancing the practicality of the contactor.

[0220] Of course, the temperature sensor may also be provided at other locations of the high-voltage circuit in other structural forms to detect the circuit signal of the high-voltage circuit, which is not limited here.

[0221] It should be noted that the positive input terminal 11 and the positive output terminal 21 constitute the main positive contactor a ( Figure 14 K1), the negative input terminal 12 and the negative output terminal 22 constitute the main negative contactor b ( Figure 14 K2), the pre-charge connection conductor 91 and the pre-charge resistor 9 constitute the pre-charge contactor c ( Figure 14 In K3), the main positive contactor a, the main negative contactor b, and the pre-charge contactor c are turned on by the actions of the first sector 411, the second sector 412, and the third sector 413, respectively. Figure 14As shown in the high voltage schematic, it can be seen that the contactor contains three DC contactors and a pre-charge resistor 9 with a discharge function. The pre-charge contactor c of the pre-charge circuit and the pre-charge resistor 9 are connected in series. There is no exposed interface on the housing 5. The two ends of their series circuit are connected to the main positive contactor a (i.e. Figure 14 The contactor does not distinguish between the first terminal 1 and the second terminal 2. During assembly, it is only necessary to ensure that the high-voltage positive and negative terminals of the same circuit are connected to the corresponding positive and negative positions on the same side of the integrated contactor baffle.

[0222] Specifically, the working principle of the contactor of the present application is described in detail below.

[0223] The first power source 42 (electric motor) receives a uniform speed rotation signal from the host computer in a stationary state, and the electric motor switches to a uniform speed rotation state.

[0224] Under the drive of the first power source 42, the rotational movement along the axis is transmitted by the rotating rod. The third sector 413 first pushes the joint 33 of the corresponding pre-charge joint conductor 91. The joint 33 is connected to the second connection end 92 on the pre-charge resistor 9 through deformation. At this time, the pre-charge circuit becomes conductive. During the whole process, the electric motor is always in a rotating state and keeps rotating ( Figure 19 Middle action 2).

[0225] Then the pre-charge contactor c and the main negative contactor b are in the on state, and the main positive contactor a is in the open state ( Figure 22 Action 3). On the whole vehicle, this corresponds to the whole vehicle being in a pre-charge state of high voltage electricity (before high voltage electricity is applied to the whole vehicle, it is necessary to pre-charge the capacitors in some on-board high-voltage components to prevent the capacitors in these high-voltage components from being short-circuited when they are instantly connected to high voltage and large current. These on-board high-voltage components include: capacitors in motor control, capacitors in generator electronic control, capacitors in compressor controller, etc.). At this time, the second fan-shaped portion 412 and the third fan-shaped portion 413 push their respective corresponding joints 33, and the main negative circuit and the pre-charge circuit are in a conductive state. Generally, the action process time of this state is X milliseconds (such as X is 200 milliseconds), and the electric motor is always in a rotating state during the entire process.

[0226] After X milliseconds, as the electric motor continues to rotate, the first sector 411 continues to rotate and pushes the corresponding joint 33, so that the main positive circuit is in the conducting state ( Figure 25Action 4). Generally, this state action process lasts Y milliseconds (e.g., Y is 500 milliseconds). During this entire process, the electric motor remains in a rotating state and continues to rotate. (Note: The values of X and Y are determined by vehicle parameters, such as the capacitance of these onboard high-voltage components, the set pre-charge capacitance percentage, the time required for vehicle insulation testing, and the program judgment time.)

[0227] After Y milliseconds, as the electric motor continues to rotate, the third sector 413 leaves the corresponding joint 33 of the pre-charge joint conductor 91, and the third sector 413 no longer pushes the corresponding joint 33, and the joint 33 returns to the state when the circuit is open, that is, the pre-charge circuit is in the open state ( Figure 27 At this point, the vehicle is in a normal high-voltage power-maintaining state. The contactor remains in this state for the entire time the vehicle requires high voltage power.

[0228] When the vehicle needs to be powered by high voltage, the electric motor receives a uniform rotation signal from the host computer and switches to a rotating state ( Figure 28 As the electric motor rotates, the second sector 412 and the first sector 411 successively leave the corresponding joint 33. The second sector 412 and the first sector 411 no longer push the corresponding joint 33, and the joint 33 returns to the state when the circuit is open, that is, the main negative and main positive circuits are in the open state ( Figure 18 At this point, the vehicle is in the low-voltage state. The contactor remains in this state for the entire time the vehicle does not require high-voltage power.

[0229] like Figure 14 and Figure 6 As shown, a vehicle charging and distribution system 1000 according to an embodiment of the present invention includes the contactor of the above embodiment.

[0230] There are two terminal groups. The first terminal 1 of one terminal group serves as a positive input terminal 11, and the second terminal 2 serves as a positive output terminal 21. The first terminal 1 of the other terminal group serves as a negative input terminal 12, and the second terminal 2 serves as a negative output terminal 22. The main bonding conductor 3 includes a first bonding conductor 3a and a second bonding conductor 3b. The first bonding conductor 3a is connected to the positive input terminal 11 and is configured to selectively mate with the positive output terminal 21. The second bonding conductor 3b is connected to the negative input terminal 12 and is configured to selectively mate with the negative output terminal 22.

[0231] Furthermore, one of the positive input terminal 11 and the positive output terminal 21 is connected to the positive terminal of the vehicle's battery terminal interface, the other of the positive input terminal 11 and the positive output terminal 21 is connected to the positive terminal of the vehicle's electronic control terminal interface, one of the negative input terminal 12 and the negative output terminal 22 is connected to the negative terminal of the battery terminal interface, and the other of the negative input terminal 12 and the negative output terminal 22 is connected to the negative terminal of the electronic control terminal interface.

[0232] It should be noted that the positive input terminal 11 and the positive output terminal 21 constitute the main positive contactor 100a ( Figure 6 K1), the negative input terminal 12 and the negative output terminal 22 constitute the main negative contactor 100b ( Figure 6 K2), the pre-charge bonding conductor 91 and the pre-charge resistor 9 constitute a pre-charge contactor 100c ( Figure 6 Middle K3).

[0233] Specifically, the charging and distribution system 1000 includes: a battery end interface, an electronic control end interface and a DC charging interface. A charging circuit is formed between the DC charging interface and the battery end interface, and a distribution circuit is formed between the electronic control end interface and the battery end interface, which are used to provide power for the entire vehicle. A main positive contactor 100a is provided on the positive end of the DC charging interface and the positive end of the battery end interface, and a main negative contactor 100b is provided on the negative end of the DC charging interface and the negative end of the battery end interface. A pre-charging circuit is also provided on the positive end of the battery end interface, and a pre-charging contactor 100c is provided on the pre-charging circuit, which is connected in series with the pre-charging resistor 9 and in parallel with the main positive contactor 100a.

[0234] It should be noted that the charging and discharging process of the vehicle has been described in the above discussion and will not be repeated here.

[0235] According to one embodiment of the present invention, Figure 29-Figure 39 As shown, the second inner shell 205 is provided with a first transmission assembly 444, a first drive coil 53 and a second drive coil 63, and the fourth contactor K4 and the fifth contactor K5 both include: a main bonding conductor 3, the main bonding conductor 3 is connected to the corresponding input end, the main bonding conductor 3 of the fourth contactor K4 is connected to the input end of the fourth contactor K4, and the main bonding conductor 3 of the fifth contactor K5 is connected to the input end of the fifth contactor K5.

[0236] Furthermore, the first transmission assembly 444 includes a first microswitch 445 and a first follower 442. The first microswitch 445 is power-connected to the first follower 442, which is connected to the main bonding conductor 3. The first drive coil 53 and the second drive coil 63 are used to generate a magnetic force to drive the first microswitch 445 in a first direction to engage the main bonding conductor 3 with the corresponding output terminal after power is applied, or to drive the first microswitch 445 in a second direction to disconnect the main bonding conductor 3 from the corresponding output terminal, thereby achieving the working effect of engaging or disconnecting the main bonding conductor 3 with the corresponding output terminal. Moreover, when the user controls the movement of the first microswitch 445, the first microswitch 445 can drive the first follower 442 to move, thereby driving the main bonding conductor 3 to move to achieve the on-off state switching of the contactor.

[0237] Furthermore, the first drive coil 53 and the second drive coil 63 are spaced apart and distributed, and the first micro switch 445 is rotatably installed around the second axis between the first drive coil 53 and the second drive coil 63. Figure 31 As shown, the first drive coil 53 and the second drive coil 63 are used to drive the first micro switch 445 to rotate about the second axis in the first direction, or the first drive coil 53 and the second drive coil 63 are used to drive the first micro switch 445 to rotate about the second axis in the second direction. It should be noted that the first direction can be clockwise and the second direction can be counterclockwise, or the first direction can be counterclockwise and the second direction can be clockwise, so that the specific structure of the contactor can be flexibly arranged according to actual needs, improving the rationality of the layout.

[0238] During the specific implementation process, a low-voltage current can be passed through the first drive coil 53 and the second drive coil 63 to generate a positive magnetic field between the first drive coil 53 and the second drive coil 63, so that the first microswitch 445 is forced to rotate in the first direction around the first axis, so that the main bonding conductor 3 is engaged with the corresponding output end, so that the contactor can conduct the high-voltage circuit; or a reverse low-voltage current can be passed through the first drive coil 53 and the second drive coil 63 to generate an opposite magnetic field between the first drive coil 53 and the second drive coil 63, so that the first microswitch 445 is forced to rotate in the second direction around the first axis, so that the main bonding conductor 3 is electrically disconnected from the corresponding output end.

[0239] Furthermore, the first transmission assembly 4 also includes: a first transmission member 443, the first transmission member 443 includes a first gear portion 431 rotating around a third axis, the first micro switch 445 includes a first arc-shaped tooth portion 441 rotating around a second axis, and the first gear portion 431 and the first arc-shaped tooth portion 441 are engaged and transmitted through a tooth structure to achieve transmission.

[0240] Furthermore, the first transmission member 443 further includes a second gear portion 432 that rotates around the third axis. The first follower 442 includes a first rack portion 421 . The second gear portion 432 and the first rack portion 421 are engaged with each other through a tooth structure for transmission.

[0241] That is to say, if Figure 33 As shown, when the first drive coil 53 and the second drive coil 63 drive the first arc-shaped tooth portion 441 to move about the first axis in the first direction, the first gear portion 431 rotates about the second axis to drive the second gear portion 432 to rotate in the same direction. The second gear portion 432 drives the first rack portion 421 to move through the tooth structure, thereby driving the main connecting conductor 3 to move, so that the first terminal 1 (input terminal) and the second terminal 2 (output terminal) are connected; Figure 35 As shown, when the first drive coil 53 and the second drive coil 63 drive the first arc-shaped tooth portion 441 to move in the second direction around the first axis, the first gear portion 431 rotates around the second axis to drive the second gear portion 432 to rotate in the same direction, and the second gear portion 432 drives the first rack portion 421 to move in the opposite direction through the tooth structure, thereby driving the main connecting conductor 3 to move in the opposite direction, so that the first terminal 1 and the second terminal 2 are disconnected.

[0242] Reference below Figure 6 、 Figure 29-Figure 39 A contactor according to an embodiment of the present invention is described.

[0243] like Figure 31 As shown, the contactor according to the embodiment of the present invention includes: a terminal group, a main bonding conductor 3 , a first transmission assembly 444 , a first drive coil 53 and a second drive coil 63 .

[0244] Among them, such as Figure 29 As shown, one end of the contactor is provided with a terminal group, which includes a first terminal 1 and a second terminal 2 that are spaced apart. Figure 31 As shown, in a specific design, the first terminal 1 and the second terminal 2 can both be constructed as terminal posts, and the high-voltage wire can be connected to the terminal posts to achieve electrical connection with the contactor.

[0245] There are at least two terminal groups, and at least two terminal groups are arranged side by side. The main bonding conductor 3 is connected to the first terminal 1, and the main bonding conductor 3 and the second terminal 2 are selectively attached. Therefore, by adjusting multiple main bonding conductors 3 simultaneously through the contactor, multiple groups of first terminal 1 and second terminal 2 can be simultaneously turned on and off, ensuring the convenience of switching the contactor on and off.

[0246] It should be noted that the first terminal 1 can be set as the input terminal and the second terminal 2 can be set as the output terminal, so that high voltage electricity can enter the contactor through the first terminal 1 and flow out of the contactor through the second terminal 2, or the first terminal 1 can be set as the output terminal and the second terminal 2 can be set as the input terminal, so that high voltage electricity can enter the contactor through the second terminal 2 and flow out of the contactor through the first terminal 1.

[0247] That is to say, the terminal groups in the present invention can be set to two groups, three groups or more groups. For example, in a specific design, the terminal groups are set to two groups, and the first terminal 1 may include a positive input terminal and a negative input terminal, and the second terminal 2 may include a positive output terminal and a negative output terminal, wherein the positive input terminal and the positive output terminal can be electrically connected through the main connecting conductor 3, and the negative input terminal and the negative output terminal can also be electrically connected through the main connecting conductor 3. Therefore, the contactor in the present invention can be constructed as an integrated on-off control structure with positive and negative poles, which has a higher degree of integration and is simpler to control and use.

[0248] The contactor is provided with a first transmission assembly 444, which includes a first microswitch 445 and a first follower 442. The first microswitch 445 is in power connection with the first follower 442, which is connected to the main bonding conductor 3. Therefore, when the user controls the movement of the first microswitch 445, the first microswitch 445 can drive the movement of the first follower 442, thereby driving the movement of the main bonding conductor 3 to achieve the on-off state of the contactor.

[0249] Among them, such as Figure 31 As shown, the driving coil has a cylindrical body, the wire is circumferentially wound around the outer wall of the cylindrical body, and the wire as a whole extends axially. When a low-voltage current is passed through the wire, the driving coil can generate a magnetic field. The magnetic field generated by the driving coil can act on the first microswitch 445. The first microswitch 445 is constructed to have a magnetic part, so that the driving coil can drive the first microswitch 445 to move.

[0250] The drive coil includes a first drive coil 53 and a second drive coil 63. Low-voltage current can be passed through the first drive coil 53 and the second drive coil 63, so that the first drive coil 53 and the second drive coil 63 can respectively construct a magnetic field. The first drive coil 53 and the second drive coil 63 are used to drive the first microswitch 445 to move in the first direction to drive the main connecting conductor 3 to engage with the second terminal 2, so that the first terminal 1 and the second terminal 2 are electrically connected, so that the contactor can conduct the circuit; the first drive coil 53 and the second drive coil 63 can also be used to drive the first microswitch 445 to move in the second direction to drive the main connecting conductor 3 to disconnect from the second terminal 2, so that the first terminal 1 and the second terminal 2 are electrically disconnected, so that the contactor can disconnect the circuit.

[0251] It can be understood that by setting the first drive coil 53 and the second drive coil 63, and making the first drive coil 53 and the second drive coil 63 drive the first micro switch 445 at the same time, the volume of a single drive coil is reduced while being able to push the first micro switch 445, so as to facilitate the overall arrangement of the contactor, and make it easy for the first drive coil 53 and the second drive coil 63 to dissipate heat, thereby improving the safety of the contactor.

[0252] The contactor of the embodiment of the present invention can drive the first micro switch 445 to move through the first drive coil 53 and the second drive coil 63, thereby driving the first follower 442 to drive the main connecting conductor 3 to move, so as to achieve synchronous connection or synchronous disconnection of multiple groups of first terminal 1 and second terminal 2, and facilitate the heat dissipation of the contactor, thereby improving the reliability and safety of the contactor.

[0253] In some embodiments, the first drive coil 53 and the second drive coil 63 are spaced apart and distributed, and the first micro switch 445 is rotatably installed around the first axis between the first drive coil 53 and the second drive coil 63. Figure 31 As shown, the first drive coil 53 and the second drive coil 63 are arranged in parallel and spaced apart, and the ends of the first drive coil 53 and the second drive coil 63 are provided with magnetic parts, and the magnetic parts are made of magnetic conductive material. When the first drive coil 53 and the second drive coil 63 are energized, the first drive coil 53 and the second drive coil 63 generate a magnetic field, and an electromagnetic space is constructed between the first drive coil 53 and the second drive coil 63. The first micro switch 445 is arranged in the electromagnetic space, so that the first drive coil 53 and the second drive coil 63 can jointly drive the first micro switch 445 to move.

[0254] The first drive coil 53 and the second drive coil 63 are used to drive the first microswitch 445 to rotate about the first axis in a first direction, or to drive the first microswitch 445 to rotate about the first axis in a second direction. It should be noted that the first direction can be clockwise and the second direction can be counterclockwise, or the first direction can be counterclockwise and the second direction can be clockwise, so that the specific structure of the contactor can be flexibly arranged according to actual needs, improving the rationality of the layout.

[0255] During the specific implementation process, a low-voltage current can be passed through the first drive coil 53 and the second drive coil 63 to generate a positive magnetic field between the first drive coil 53 and the second drive coil 63, so that the first microswitch 445 is forced to rotate in the first direction around the first axis, so that the first terminal 1 and the second terminal 2 are electrically connected, so that the contactor can conduct the high-voltage circuit; or a reverse low-voltage current can be passed through the first drive coil 53 and the second drive coil 63 to generate an opposite magnetic field between the first drive coil 53 and the second drive coil 63, so that the first microswitch 445 is forced to rotate in the second direction around the first axis, so that the first terminal 1 and the second terminal 2 are electrically disconnected.

[0256] Through the above arrangement, the first drive coil 53 and the second drive coil 63 can act together on the magnetic drive unit 44, so that the magnetic drive unit 44 has sufficient torque to drive the main bonding conductor 3 to move, thereby achieving stable switching of the on and off states of the high-voltage line.

[0257] In some embodiments, as Figure 38 As shown, the first drive coil 53 includes a first magnetic conductive portion 54 and a second magnetic conductive portion 52, and the second drive coil 63 includes a third magnetic conductive portion 61 and a fourth magnetic conductive portion 62. When the first drive coil 53 and the second drive coil 63 are energized, the polarity of the first magnetic conductive portion 54 is opposite to that of the second magnetic conductive portion 61, and the polarity of the third magnetic conductive portion 61 is opposite to that of the fourth magnetic conductive portion 62. The polarity of the first magnetic conductive portion 54 and the third magnetic conductive portion 61 is opposite, and the polarity of the second magnetic conductive portion 52 and the fourth magnetic conductive portion 62 is opposite.

[0258] That is to say, if Figure 38As shown, the main parts of the first magnetic conductive part 54, the second magnetic conductive part 52, the third magnetic conductive part 61 and the fourth magnetic conductive part 62 are constructed as a plate-like structure. The main part of the first magnetic conductive part 54 and the main part of the second magnetic conductive part 52 are fitted at both ends of the first drive coil 53 and fitted at the end of the first drive coil 53. The main parts of the third magnetic conductive part 61 and the fourth magnetic conductive part 62 are arranged at both ends of the second drive coil 63 and fitted at the end of the second drive coil 63. Therefore, when a low-voltage current is passed through the first drive coil 53 and the second drive coil 63, the first magnetic conductive part 54 and the second magnetic conductive part 52 produce opposite polarities, and when a low-voltage current is passed through the second drive coil 63, the third magnetic conductive part 61 and the fourth magnetic conductive part 62 also produce opposite polarities.

[0259] Among them, such as Figure 38 As shown, the main part of the magnetic conductive part is connected to a folding plate, which extends into the gap between the first drive coil 53 and the second drive coil 63. The folding plate of the first magnetic conductive part 54 and the folding plate of the third magnetic conductive part 61 are arranged opposite to each other, and the folding plate of the second magnetic conductive part 52 and the folding plate of the fourth magnetic conductive part 62 are arranged opposite to each other. By passing a low-voltage current through the first drive coil 53 and the second drive coil 63, the polarity of the first magnetic conductive part 54 and the third magnetic conductive part 61 are opposite, and the polarity of the second magnetic conductive part 52 and the fourth magnetic conductive part 62 are opposite.

[0260] The first micro switch 445 includes a magnetic drive part 44, wherein the first end of the magnetic drive part 44 is located between the first magnetic conductive part 54 and the third magnetic conductive part 61, and the second end of the magnetic drive part 44 is located between the second magnetic conductive part 52 and the fourth magnetic conductive part 62, and the polarity of the first end and the second end of the magnetic drive part 44 is the same.

[0261] Specifically, both ends of the magnetic driving portion 44 can be set to be N poles. When the first driving coil 53 and the second driving coil 63 are supplied with low voltage current, the second magnetic conductive portion 52 and the third magnetic conductive portion 61 can be made to have N poles, and the first magnetic conductive portion 54 and the fourth magnetic conductive portion 62 can be made to have S poles. Figure 32 As shown, the first magnetic conductive portion 54 and the first end of the magnetic driving portion 44 attract each other, and the third magnetic conductive portion 61 and the first end of the magnetic driving portion 44 repel each other, the second magnetic conductive portion 52 and the second end of the magnetic driving portion 44 repel each other, and the fourth magnetic conductive portion 62 and the second end of the magnetic driving portion 44 attract each other, so that the magnetic driving portion 44 can move in the first direction (i.e., around the first axis) Figure 31 The first end of the magnetic driving portion 44 is adhered to and adsorbed on the first magnetic conductive portion 54, and the second end of the magnetic driving portion 44 is adhered to and adsorbed on the fourth magnetic conductive portion 62, so that the first terminal 1 and the second terminal 2 are connected.

[0262] Or as Figure 34As shown, when the first drive coil 53 and the second drive coil 63 are supplied with reverse low-voltage current, the second magnetic conductive portion 52 and the third magnetic conductive portion 61 can have S poles, and the first magnetic conductive portion 54 and the fourth magnetic conductive portion 62 can have N poles. As a result, the first magnetic conductive portion 54 and the first end of the magnetic drive portion 44 repel each other, and the third magnetic conductive portion 61 and the first end of the magnetic drive portion 44 attract each other, the second magnetic conductive portion 52 and the second end of the magnetic drive portion 44 attract each other, and the fourth magnetic conductive portion 62 and the second end of the magnetic drive portion 44 repel each other, so that the magnetic drive portion 44 can rotate around the first axis in the second direction (i.e. Figure 31 ), so that the first end of the magnetic drive portion 44 is adhered and adsorbed on the third magnetic conductive portion 61, and the second end of the magnetic drive portion 44 is adhered and adsorbed on the second magnetic conductive portion 52, so that the first terminal 1 and the second terminal 2 are disconnected.

[0263] In some embodiments, as Figure 39 As shown, the first drive coil 53 includes a first magnetic conductive portion 54 and a second magnetic conductive portion 52, and the second drive coil 63 includes a third magnetic conductive portion 61 and a fourth magnetic conductive portion 62. When the first drive coil 53 and the second drive coil 63 are energized, the polarity of the first magnetic conductive portion 54 is opposite to that of the second magnetic conductive portion 52, and the polarity of the third magnetic conductive portion 61 is opposite to that of the fourth magnetic conductive portion 62. The polarity of the first magnetic conductive portion 54 and the third magnetic conductive portion 61 is the same, and the polarity of the second magnetic conductive portion 52 and the fourth magnetic conductive portion 62 is the same.

[0264] That is to say, if Figure 39 As shown, the main parts of the first magnetic conductive part 54, the second magnetic conductive part 52, the third magnetic conductive part 61 and the fourth magnetic conductive part 62 are constructed as a plate-like structure. The main part of the first magnetic conductive part 54 and the main part of the second magnetic conductive part 52 are fitted at both ends of the first drive coil 53 and are arranged opposite to the end of the first drive coil 53. The main parts of the third magnetic conductive part 61 and the fourth magnetic conductive part 62 are fitted at both ends of the second drive coil 63 and are arranged opposite to the end of the second drive coil 63. Therefore, when a low-voltage current is passed through the first drive coil 53 and the second drive coil 63, the first magnetic conductive part 54 and the second magnetic conductive part 52 produce opposite polarities, and when a low-voltage current is passed through the second drive coil 63, the third magnetic conductive part 61 and the fourth magnetic conductive part 62 also produce opposite polarities.

[0265] Among them, such as Figure 39As shown, the main body of the magnetic conductive part is connected to a folding plate, which extends into the gap between the first drive coil 53 and the second drive coil 63. The folding plate of the first magnetic conductive part 54 and the folding plate of the third magnetic conductive part 61 are arranged opposite to each other, and the folding plate of the second magnetic conductive part 52 and the folding plate of the fourth magnetic conductive part 62 are arranged opposite to each other. By passing a low-voltage current through the first drive coil 53 and the second drive coil 63, the polarity of the first magnetic conductive part 54 and the third magnetic conductive part 61 are made the same, and the polarity of the second magnetic conductive part 52 and the fourth magnetic conductive part 62 are made the same.

[0266] The first micro switch 445 includes a magnetic drive part 44, wherein the first end of the magnetic drive part 44 is located between the first magnetic conductive part 54 and the third magnetic conductive part 61, and the second end of the magnetic drive part 44 is located between the second magnetic conductive part 52 and the fourth magnetic conductive part 62. The portion of the first end of the magnetic drive part 44 close to the first drive coil 53 has an opposite polarity to the portion close to the second drive coil 63, and the portion of the second end of the magnetic drive part 44 close to the first drive coil 53 has an opposite polarity to the portion close to the second drive coil 63. The portions of the first end and the second end of the magnetic drive part 44 close to the first drive coil 53 have the same polarity, and the portions of the first end and the second end of the magnetic drive part 44 close to the second drive coil 63 have the same polarity.

[0267] Specifically, the end of the magnetic driving portion 44 facing the first driving coil 53 can be set as the N pole, and the end of the magnetic driving portion 44 facing the second driving coil 63 can be set as the S pole. Further, when the first driving coil 53 and the second driving coil 63 are supplied with low-voltage current, the first magnetic conductive portion 54 and the third magnetic conductive portion 61 can have S poles, and the second magnetic conductive portion 52 and the fourth magnetic conductive portion 62 can have N poles. Figure 32 As shown, the first magnetic conductive portion 54 and the first end of the magnetic driving portion 44 attract each other, and the third magnetic conductive portion 61 and the first end of the magnetic driving portion 44 repel each other, the second magnetic conductive portion 52 and the second end of the magnetic driving portion 44 repel each other, and the fourth magnetic conductive portion 62 and the second end of the magnetic driving portion 44 attract each other, so that the magnetic driving portion 44 can move in the first direction (i.e., around the first axis) Figure 31 The first end of the magnetic driving portion 44 is adhered to and adsorbed on the first magnetic conductive portion 54, and the second end of the magnetic driving portion 44 is adhered to and adsorbed on the fourth magnetic conductive portion 62, so that the first terminal 1 and the second terminal 2 are connected.

[0268] Or as Figure 34As shown, when the first drive coil 53 and the second drive coil 63 are supplied with reverse low-voltage current, the first magnetic conductive portion 54 and the third magnetic conductive portion 61 can have N poles, and the second magnetic conductive portion 52 and the fourth magnetic conductive portion 62 can have S poles. As a result, the first magnetic conductive portion 54 and the first end of the magnetic drive portion 44 repel each other, and the third magnetic conductive portion 61 and the first end of the magnetic drive portion 44 attract each other, the second magnetic conductive portion 52 and the second end of the magnetic drive portion 44 attract each other, and the fourth magnetic conductive portion 62 and the second end of the magnetic drive portion 44 repel each other, so that the magnetic drive portion 44 can rotate around the first axis in the second direction (i.e. Figure 31 ), so that the first end of the magnetic drive portion 44 is adhered and adsorbed on the third magnetic conductive portion 61, and the second end of the magnetic drive portion 44 is adhered and adsorbed on the second magnetic conductive portion 52, so that the first terminal 1 and the second terminal 2 are disconnected.

[0269] Through the above-mentioned arrangement, the ends of the magnetic drive part 44 on both sides of the first axis are subjected to opposite forces respectively, so that the magnetic drive part 44 can rotate stably around the first axis, thereby driving the main connecting conductor 3 to move, thereby realizing stable switching of the on and off state of the high-voltage line, and the distance between the first drive coil 53 and the second drive coil 63 can be adjusted according to actual needs to adjust the stroke size of the first microswitch 445, so that the first microswitch 445 has a larger stroke range, and the assembly method between the first microswitch 445 and the drive coil is more flexible and diverse.

[0270] In some embodiments, the first drive coil 53 and the second drive coil 63 are connected in series in the control circuit. Thus, the on and off of the first drive coil 53 and the second drive coil 63 can be synchronously controlled by a single voltage signal, thereby improving the overall reliability of the contactor.

[0271] In some embodiments, as Figure 37 As shown, the first transmission assembly 444 also includes a first transmission member 443, which includes a first gear portion 431 that rotates around the second axis. The first gear portion 431 can be a bevel gear portion or a spur gear portion. The first micro switch 445 includes a first arcuate tooth portion 441 that rotates around the first axis. The first gear portion 431 and the first arcuate tooth portion 441 are engaged and transmitted through a tooth structure. The first arcuate tooth portion 441 is fixedly connected to the magnetic drive portion 44 and can move together with the magnetic drive portion 44. The first arcuate tooth portion 441 is constructed as a fan-shaped structure, and a tooth structure is provided on the side of the first arcuate tooth portion 441 away from the first axis. The outer side of the first gear portion 431 is constructed with a tooth structure corresponding to the first arcuate tooth portion 441. The first arcuate tooth portion 441 is engaged with the first gear portion 431 to achieve transmission.

[0272] That is to say, if Figure 32 As shown, when the first drive coil 53 and the second drive coil 63 drive the magnetic drive portion 44 to move around the first axis in the first direction, the magnetic drive portion 44 drives the first arc-shaped tooth portion 441 to move around the first axis in the first direction. The first arc-shaped tooth portion 441 can drive the first gear portion 431 to rotate around the second axis through the tooth structure, thereby driving the main connecting conductor 3 to move, so that the first terminal 1 and the second terminal 2 are connected; Figure 34 As shown, when the first drive coil 53 and the second drive coil 63 drive the magnetic drive part 44 to move around the first axis toward the second direction, the magnetic drive part 44 drives the first arc-shaped tooth part 441 to move around the first axis toward the second direction, and the first arc-shaped tooth part 441 can drive the first gear part 431 to rotate around the second axis through the tooth structure to drive the main connecting conductor 3 to move in the opposite direction, so that the first terminal 1 and the second terminal 2 are disconnected.

[0273] In some embodiments, as Figure 37 As shown, the first transmission member 443 also includes a second gear portion 432 that rotates around a second axis. The second gear portion 432 is a spur gear portion. The first gear portion 431 is directly connected to the end of the second gear portion 432, and the axes of the first gear portion 431 and the second gear portion 432 coincide with each other. The first gear portion 431 is used to drive the second gear portion 432 to rotate around the second axis. The first follower 442 includes a first rack portion 421. The first rack portion 421 is constructed as a columnar structure. The first rack portion 421 is provided with a tooth structure extending along the length direction. The second gear portion 432 and the first rack portion 421 are engaged and transmitted through the tooth structure.

[0274] That is to say, if Figure 33 As shown, when the first drive coil 53 and the second drive coil 63 drive the first arc-shaped tooth portion 441 to move about the first axis in the first direction, the first gear portion 431 rotates about the second axis to drive the second gear portion 432 to rotate in the same direction. The second gear portion 432 drives the first rack portion 421 to move through the tooth structure, thereby driving the main connecting conductor 3 to move, so that the first terminal 1 and the second terminal 2 are connected; Figure 35 As shown, when the first drive coil 53 and the second drive coil 63 drive the first arc-shaped tooth portion 441 to move in the second direction around the first axis, the first gear portion 431 rotates around the second axis to drive the second gear portion 432 to rotate in the same direction, and the second gear portion 432 drives the first rack portion 421 to move in the opposite direction through the tooth structure, thereby driving the main connecting conductor 3 to move in the opposite direction, so that the first terminal 1 and the second terminal 2 are disconnected.

[0275] Through the above-mentioned arrangement, the rotation of the magnetic drive part 44 around the first axis is converted into the sliding of the first rack part 421 along a fixed direction to drive the main connecting conductor 3 to move, thereby realizing the connection and disconnection of the first terminal 1 and the second terminal 2, and making the sliding process smooth and stable, reducing the impact force when the main connecting conductor 3 is connected to the second terminal 2, thereby reducing the contact closure noise and improving the stability of the contactor.

[0276] In some embodiments, the diameter of the second gear portion 432 is greater than the diameter of the first gear portion 431. In other words, when the first gear portion 431 drives the second gear portion 432 to rotate, the rotational travel of the second gear portion 432 is greater than the rotational travel of the first gear portion 431. As a result, the travel of the first microswitch 445 can be amplified by the first transmission member 443, reducing the travel requirement of the first microswitch 445 during the switching process, facilitating the realization of a diverse layout of the entire contactor, and meeting the electrical clearance requirements of high voltage.

[0277] In some embodiments, the first rack portion 421 extends vertically, and the upper end of the first rack portion 421 is used to connect to the main bonding conductor 3, and the side wall of the lower end of the first rack portion 421 is provided with a tooth structure that meshes with the second gear portion 432. Figure 31 As shown, the first rack portion 421 is installed on one side of the second gear portion 432. The first rack portion 421 is constructed as a columnar structure. A tooth structure extending vertically is provided on one side of the first rack portion 421 close to the second gear portion 432. The first rack portion 421 can engage with the second gear portion 432 to perform transmission.

[0278] Therefore, when the driving coil 5 drives the arc-shaped tooth portion 411 to move in the first direction around the first axis, the second gear portion 432 drives the first rack portion 421 to move vertically upward through the tooth structure, so as to drive the main connecting conductor 3 to move upward, so that the first terminal 1 and the second terminal 2 are connected; and when the driving coil 5 drives the arc-shaped tooth portion 411 to move in the second direction around the first axis, the second gear portion 432 drives the first rack portion 421 to move vertically downward through the tooth structure, so as to drive the main connecting conductor 3 to move downward, so that the first terminal 1 and the second terminal 2 are disconnected.

[0279] Through the above-mentioned arrangement, the side surfaces of the main bonding conductor 3 can be attached to the side surfaces of the first input terminal 1 and the second output terminal 2 to serve as moving contacts, thereby reducing the number of moving contacts and providing the moving contacts with a sufficient bonding area to reduce the contact resistance of the moving contacts, thereby reducing the heat generation of the contactor, reducing energy loss, and reducing the possibility of adhesion of the moving contacts.

[0280] Further, such as Figure 31As shown, by sequentially arranging the plurality of main bonding conductors 3 and the first drive coil 53 and the second drive coil 63 in the vertical direction, and making the drive coil 5 and the first micro switch 445 in the horizontal direction ( Figure 31 The left and right directions in the figure are arranged opposite each other, so that the overall layout of the contactor is uniform, which is conducive to overall heat dissipation.

[0281] In some embodiments, as Figure 31 As shown, the main bonding conductor 3 is constructed in a plate shape, and a plurality of main bonding conductors 3 are provided, and the plurality of main bonding conductors 3 respectively correspond to a plurality of groups of first wiring terminals 1 and second wiring terminals 2, and the plurality of main bonding conductors 3 are all arranged along the axial extension of the drive coil so as to be evenly arranged on the upper side of the first drive coil 53 and the second drive coil 63, so that the overall layout of the contactor is reasonable.

[0282] It should be noted that the material of the main bonding conductor 3 can be a composite material such as soft copper (silver), so that the main bonding conductor 3 has a larger current carrying capacity, further reducing the resistance of the main bonding conductor 3. At the same time, the hardness of the main bonding conductor 3 is reduced, reducing the noise during the bonding process between the second terminal 2 and the main bonding conductor 3.

[0283] And as Figure 37 As shown, the first follower 442 includes a clamping portion 422 having a clamping opening 423 open toward the main bonding conductor 3. A groove is provided on the side of the clamping portion 422 away from the main bonding conductor 3. A first rack portion 421 is fixed to the inner sidewall of the groove and is used to drive the clamping portion 422 to move vertically. One end of the main bonding conductor 3 is in contact with the first terminal 1, and the other end of the main bonding conductor 3 extends into the clamping opening 423. The clamping portion 422 is used to drive the other end of the main bonding conductor 3 into contact with the second terminal 2.

[0284] Specifically, the first terminal 1 and the second terminal 2 can be arranged at the same height, and the end of the main bonding conductor 3 away from the clamping portion 422 is extended to the lower side of the first terminal 1, so that the upper side of the main bonding conductor 3 is closely connected to the lower side of the first terminal 1, and at the same time, the end of the main bonding conductor 3 close to the clamping portion 422 is extended into the clamping opening 423, so that the clamping portion 422 can limit the main bonding conductor 3. When the first rack portion 421 moves, the clamping portion 422 can drive the main bonding conductor 3 to move in the same direction. The second terminal 2 is arranged at the upper end of the side of the main bonding conductor 3 close to the clamping portion 422, as shown in FIG. Figure 33 As shown, when the main bonding conductor 3 moves to the upper limit position (ie, the vertical maximum position), the main bonding conductor 3 is connected to the second terminal 2, as shown in FIG. Figure 35As shown, when the clamping portion 422 drives the main bonding conductor 3 to move downward, the main bonding conductor 3 is disconnected from the second terminal 2, so that the first terminal 1 and the second terminal 2 are electrically disconnected.

[0285] It should be noted that the ends of multiple main bonding conductors 3 are all extended into the same clamping opening 423, and the clamping portion 422 can drive the multiple main bonding conductors 3 to move synchronously, thereby realizing the synchronous connection and disconnection of multiple groups of first terminal blocks 1 and second terminal blocks 2, and reducing the number of parts and the difficulty of installation.

[0286] In some embodiments, as Figure 33 As shown, the main bonding conductor 3 includes a fixing portion 31 and a bonding portion 33 . The fixing portion 31 is fixedly connected to the first terminal 1 . The first follower 442 is connected to the bonding portion 33 to drive the bonding portion 33 to bond with the second terminal 2 .

[0287] It can be understood that when the first micro switch 445 rotates about the first axis toward the first direction, the first follower 442 moves toward the direction away from the second terminal 2, and the first follower 442 applies a force on the joint 33 away from the second terminal 2, and the fixed part 31 and the joint 33 move relative to each other, so that the main joint conductor 3 is disconnected from the second terminal 2; and when the first micro switch 445 rotates about the first axis toward the second direction, the first follower 442 moves toward the direction close to the second terminal 2, and the second terminal 2 and the joint 33 are engaged, thereby realizing convenient switching of the on and off states of the high-voltage line.

[0288] In some embodiments, as Figure 33 As shown, a weakened portion 32 is connected between the fixed portion 31 and the engaging portion 33. Specifically, when the rack portion moves downward, it applies a downward force to the engaging portion 33, causing the weakened portion 32 to elastically deform. This causes relative movement between the fixed portion 31 and the engaging portion 33, disconnecting the main engaging conductor 3 from the second output terminal 2. When the first microswitch 445 rotates about the first axis in the second direction, the rack portion moves upward, restoring the elastic deformation of the weakened portion 32 and engaging the second output terminal 2 with the engaging portion 33.

[0289] Therefore, by providing the weakened portion 32, relative movement between the fixing portion 31 and the joining portion 33 is achieved, and plastic deformation of the joining portion 33 is avoided, so that the joining portion 33 can be repeatedly attached to the side of the second terminal 2, thereby improving the stability and reliability of the contactor.

[0290] In some embodiments, the weakened portion 32 is constructed as an arc segment, one end of the arc segment is connected to the fixing portion 31, and the other end is connected to the joint portion 33, and the weakened portion 32 has a weakened cavity 321. Figure 33As shown, the weakened portion 32 can be constructed as a downwardly protruding semicircular arc segment, the left end of the weakened portion 32 is connected to the fixing portion 31 , and the right end of the weakened portion 32 is connected to the joining portion 33 to jointly construct the main joining conductor 3 .

[0291] Furthermore, when the first follower 442 applies a downward force to the joint portion 33, the weakened portion 32 compresses and deforms, causing relative movement between the fixed portion 31 and the joint portion 33, disconnecting the main joint conductor 3 from the second terminal 2. When the first follower 442 moves upward, the elastic deformation of the weakened portion 32 is restored, and the second terminal 2 and the joint portion 33 engage. The provision of an arc-shaped weakened cavity 321 within the weakened portion 32 further reduces the overall stiffness of the weakened portion 32, making it easier for the weakened portion 32 to elastically deform when subjected to the force transmitted by the joint portion 33, thereby reducing the size requirements of the first drive coil 53 and the second drive coil 63.

[0292] In some embodiments, as Figure 29 As shown, the contactor of the embodiment of the present invention further includes a second inner housing 205. The first terminal 1 and the second terminal 2 are mounted on the second inner housing 205. The main bonding conductor 3, the first transmission assembly 444, the first drive coil 53 and the second drive coil 63 are all mounted in the second inner housing 205. The first follower 442 is in sliding engagement with the inner circumferential wall of the second inner housing 205.

[0293] That is to say, if Figure 29 As shown, the second inner shell 205 is constructed as a rectangular structure. Outwardly protruding legs 76 are provided at the diagonal positions of the second inner shell 205. These legs 76 have mounting holes 72 extending through the thickness of the second inner shell 205. Connectors can be inserted through these holes to secure the contactor. The external structure of the second inner shell 205 is consistent with that of traditional contactors, facilitating structural design and material switching. It should be noted that the sidewalls of the second inner shell 205 have openings through which low-voltage signal lines can pass through the second inner shell 205 to electrically connect to an external power source. The operator can control the on / off of the contactor using an external switch. The low-voltage signal lines can also be designed as connectors.

[0294] Furthermore, if Figure 30As shown, the second inner shell 205 has an outwardly open cavity structure. A cover structure 73 is provided at the open end. The cover structure 73 has through-holes corresponding to the first and second terminals 1 and 2. The upper portions of the first and second terminals 1 and 2 can extend into the through-holes to be mounted on the cover structure 73, thereby maintaining relative stability with the second inner shell 205. This allows the main connecting conductor 3 to move relative to the second terminal 2. The remaining portions of the first and second terminals 1 and 2, as well as the main connecting conductor 3, the first transmission assembly 444, the first drive coil 53, and the second drive coil 63 are all sealed within the second inner shell 205 by the cover structure 73, thereby isolating them from the outside world. This prevents foreign matter from entering the second inner shell 205 and provides insulation protection. Furthermore, the inner circumferential wall of the second inner shell 205 can limit the first follower 442, allowing it to slide in the same direction relative to the inner circumferential wall, ensuring a stable movement path for the main connecting conductor 3 and improving the reliability of the contactor operation.

[0295] In some embodiments, the inner peripheral wall of the second inner shell 205 is provided with a sliding guide groove 74, and the first rack portion 421 of the first follower 442 is slidably engaged with the sliding guide groove 74. Figure 36 As shown, the sliding guide groove 74 extends in the vertical direction, and the opening size of the sliding guide groove 74 is equal to the width size of the first rack portion 421. When the first rack portion 421 is installed in the sliding guide groove 74, the sliding guide groove 74 can limit the first rack portion 421 so that the first rack portion 421 can reciprocate in the height direction, thereby ensuring that the contact and disengagement process between the main bonding conductor 3 and the first terminal 1 is reliable, thereby improving the stability of the contactor.

[0296] In some embodiments, the contactor of the present invention further includes: a temperature sensor and a controller, wherein the temperature sensor is electrically connected to the controller, and the temperature sensor is used to detect circuit signals of the first terminal 1, the second terminal 2, and / or the main bonding conductor 3, and the controller is used to control the main bonding conductor 3 to engage or disconnect with the second terminal 2 according to the circuit signals; wherein the circuit signals include: temperature changes, voltage changes, and current changes. In other words, a temperature sensor can be set to monitor the main bonding conductor 3, or a temperature sensor can be set to detect the first terminal 1 and the second terminal 2, or a temperature sensor can be set to detect the first terminal 1, the second terminal 2, and the main bonding conductor 3 at the same time, thereby obtaining temperature changes, voltage changes, and current changes of the high-voltage line.

[0297] Furthermore, as the first terminal 1 and the second terminal 2 are connected through the main bonding conductor 3, the current and heat generation of the high-voltage line will change, and corresponding temperature changes will occur. The sensor can obtain the change information of the high-voltage line during operation (including temperature changes, voltage changes and current changes), and transmit it to the controller in the form of a circuit signal. The controller determines whether the cut-off threshold of the high-voltage line is reached based on the circuit signal, and when the high-voltage circuit needs to be disconnected, the controller controls the drive component to disconnect the electrical connection between the second terminal 2 and the main bonding conductor 3. Not only does it not need to set a fuse to reduce high-voltage loss, but it also reduces costs.

[0298] After controlling the contactor to disconnect, if the electrical equipment using the contactor of the present invention needs to continue operating, the controller can use the drive assembly to connect the second terminal 2 with the main connecting conductor 3 to ensure that the electrical equipment can be supplied with high voltage, thereby improving safety. For example, if the contactor of the present invention is used in an electric vehicle and circuit information indicates that the contactor needs to be disconnected but the vehicle is in a dangerous situation and needs to maintain operating conditions, the high voltage state can be maintained. After the vehicle reaches a safe location or the dangerous situation is resolved, the electrical connection between the second terminal 2 and the main connecting conductor 3 can be disconnected.

[0299] According to a specific embodiment of the present invention, Figures 40-44 As shown, the fourth contactor K4 and the fifth contactor K5 each include a main bonding conductor 3 connected to the corresponding input terminal and selectively electrically connected to the corresponding output terminal. It should be noted that the fourth contactor K4 and the fifth contactor K5 are each provided with a corresponding main bonding conductor 3. Taking the fourth contactor K4 as an example, the main bonding conductor 3 of the fourth contactor K4 is connected to the input terminal of the fourth contactor K4 and selectively electrically connected to the output terminal of the fourth contactor K4.

[0300] like Figure 40 As shown, the contactor of the present invention is integrated with at least two terminal groups, that is, the number of terminal groups can be flexibly set according to actual usage requirements. Preferably, the contactor is provided with two groups of first terminals 1 and second terminals 2. It should be noted that one first terminal 1 (input terminal) corresponds to one second terminal 2 (output terminal), and a group of first terminals 1 and second terminals 2 can form a DC circuit. In other words, the contactor of the present invention can be integrated with at least two DC circuits. At least two main bonding conductors 3, and the main bonding conductors 3 correspond one-to-one to the terminal groups.

[0301] like Figure 41As shown, a driving mechanism 75 is provided in the second inner shell 205, and the driving mechanism 75 includes a fourth fan-shaped driving portion 77. The fourth fan-shaped driving portion 77 is constructed to be rotatable around a fourth axis, and the fourth fan-shaped driving portion 77 can be constructed as a fan-shaped sheet structure; wherein, the fourth fan-shaped driving portion 77 pushes the main bonding conductor 3 of the fourth contactor K4 and the main bonding conductor 3 of the fifth contactor K5 during the rotation process, and releases the push on the main bonding conductor 3 of the fourth contactor K4 and the main bonding conductor 3 of the fifth contactor K5. When the fourth fan-shaped driving portion 77 pushes multiple main bonding conductors 3, the multiple main bonding conductors 3 are electrically connected to the corresponding output ends respectively.

[0302] Among them, the driving mechanism 75 and the host computer use CAN (Controller Area Network) communication control, which is used to realize synchronous control of the two terminal groups according to the CAN signal control, ensure the synchronization of the two groups of first terminal 1 and second terminal 2, and facilitate the user to control the contactor.

[0303] Preferably, if Figure 15 、 Figure 17 and Figure 18 As shown, the main bonding conductor 3 can be connected to the first terminal 1 through a metal conductor 10. The metal conductor 10 is provided between the first terminal 1 and the main bonding conductor 3. By providing the metal conductor 10, it can play a conductive role between the first terminal 1 and the main bonding conductor 3, and one end of the main bonding conductor 3 can be connected to the metal conductor 10 in a fitting manner, thereby ensuring the conductivity between the first terminal 1 and the main bonding conductor 3. The fourth sector-shaped driving portion 77 can push the multiple main bonding conductors 3 and release the push on the multiple main bonding conductors 3 when rotating. Specifically, When the fourth fan-shaped driving part 77 rotates, when the fourth fan-shaped driving part 77 rotates to an appropriate position, it will generate a driving force on the multiple main bonding conductors 3, so that the fourth fan-shaped driving part 77 pushes the multiple main bonding conductors 3 to make the main bonding conductors 3 elastically deform so as to fit with the second terminal 2, and when the fourth fan-shaped driving part 77 continues to rotate to another position, the fourth fan-shaped driving part 77 separates from the main bonding conductors 3 to loosen the main bonding conductors 3. At this time, the main bonding conductors 3 will rely on their own elasticity to reset, thereby separating the main bonding conductors 3 from the second terminal 2.

[0304] It should be noted that in some examples, such as Figures 40-44 In the embodiment shown, the contactor also includes a reset drive structure, which is used to drive the main bonding conductor 3 to separate from the second terminal 2, that is, the electrical connection between the main bonding conductor 3 and the second terminal 2 can be disconnected by the reset drive structure. For example, the reset drive structure can be a torsion spring, which uses the elastic deformation force of the torsion spring to push the main bonding conductor 3 to separate from the second terminal 2. Of course, the reset drive structure can also be set to other structures, as long as the structure can achieve the above-mentioned effect, and is not limited here.

[0305] like Figure 41 As shown, the fourth fan-shaped driving portion 77 includes a first sub-fan-shaped portion 78 and a second sub-fan-shaped portion 79 spaced apart and distributed along the fourth axis, the main bonding conductor 3 includes a third bonding conductor 3c and a fourth bonding conductor 3d, the first sub-fan-shaped portion 78 is used to push the third bonding conductor 3c and release the push on the third bonding conductor 3c, and the second sub-fan-shaped portion 79 is used to push the fourth bonding conductor 3d and release the push on the fourth bonding conductor 3d.

[0306] Therefore, the first sub-fan-shaped portion 78 can selectively push or release the third bonding conductor 3c, and the second sub-fan-shaped portion 79 can selectively push or release the fourth bonding conductor 3d, thereby controlling the working state of the contactor and meeting different DC charging needs of users.

[0307] It should be noted that when multiple groups of terminal groups are integrated in the contactor, the number of main bonding conductors 3 and the number of fourth fan-shaped drive parts 77 should be the same as the number of terminal groups, thereby realizing synchronous control of multiple groups of terminal groups, thereby improving the synchronization of the contactor.

[0308] Furthermore, if Figure 41 As shown, the first sub-sector-shaped portion 78 and the second sub-sector-shaped portion 79 are arranged opposite each other along the fourth axis, that is, the projections of the first sub-sector-shaped portion 78 and the second sub-sector-shaped portion 79 on the fourth axis coincide with each other, and the first sub-sector-shaped portion 78 and the second sub-sector-shaped portion 79 rotate synchronously about the fourth axis. During the rotation process, the first sub-sector-shaped portion 78 and the second sub-sector-shaped portion 79 simultaneously push the third bonding conductor 3c and the fourth bonding conductor 3d, and simultaneously release the push on the third bonding conductor 3c and the fourth bonding conductor 3d. Thus, it is possible to ensure that the first sub-sector-shaped portion 78 and the second sub-sector-shaped portion 79 can simultaneously push or release the third bonding conductor 3c and the fourth bonding conductor 3d, thereby achieving synchronous control of the third bonding conductor 3c and the fourth bonding conductor 3d, and further achieving synchronous disconnection or conduction of the first terminal 1 (input terminal) and the second terminal 2 (output terminal), thereby enhancing the synchronization of the contactor.

[0309] like Figure 41 As shown, the driving mechanism 75 also includes: a second power source 791 and a second transmission rod 792, the second power source 791 is connected to the end of the second transmission rod 792 and is used to drive the second transmission rod 792 to rotate, the first sub-fan-shaped portion 78 and the second sub-fan-shaped portion 79 are both provided on the second transmission rod 792, the first sub-fan-shaped portion 78 and the second sub-fan-shaped portion 79 both rotate synchronously around the fourth axis, and the fourth axis coincides with the axis of the second transmission rod 792.

[0310] The second power source 791 is electrically connected to the host computer. The second power source 791 can be constructed as an electric motor, which facilitates the control of the speed and direction of the electric motor by the host computer. It should be noted that the rotation direction of the second transmission rod 792 is clockwise, and the second transmission rod 792 can rotate at a uniform speed or a non-uniform speed. The second power source 791 is connected to the end of the second transmission rod 792, and the other end of the second transmission rod 792 extends in a direction away from the second power source 791. The fourth axis coincides with the axis of the second transmission rod 792 to ensure that the second transmission rod 792 can rotate along the fourth axis under the action of the second power source 791, thereby facilitating the second power source 791 to provide driving force for the second transmission rod 792 and increase the rotation speed of the second transmission rod 792.

[0311] Specifically, if Figure 41 As shown, the first sub-fan-shaped portion 78 and the second sub-fan-shaped portion 79 are both provided on the second transmission rod 792 and are distributed in sequence along the axial direction of the second transmission rod 792, so that the first sub-fan-shaped portion 78 and the second sub-fan-shaped portion 79 can simultaneously control the third bonding conductor 3c and the fourth bonding conductor 3d, so that the third bonding conductor 3c and the fourth bonding conductor 3d can synchronously turn on or off the two groups of first wiring terminals 1 and second wiring terminals 2, thereby realizing synchronous control of the two groups of first wiring terminals 1 and second wiring terminals 2, thereby improving the synchronization of the contactor.

[0312] According to some specific embodiments of the present invention, Figures 45-55 As shown, the distributor 2000 also includes: a third inner shell 206 and a fourth inner shell 207. The third inner shell 206 and the fourth inner shell 207 are both fixedly arranged in the outer shell 200. The fourth contactor K4 is arranged in the third inner shell 206. The fifth contactor K5 is arranged in the fourth inner shell 207. The input end and the output end of the fourth contactor K4 are both arranged on the third inner shell 206. The input end and the output end of the fifth contactor K5 are both arranged on the fourth inner shell 207.

[0313] Furthermore, the fourth contactor K4 and / or the fifth contactor K5 include: a second transmission assembly 100, a main bonding conductor 3 and a third drive coil 112, and the main bonding conductor 3 is connected to the corresponding input end, for example: the main bonding conductor 3 of the fourth contactor K4 is connected to the input end of the fourth contactor K4.

[0314] The second transmission assembly 100 includes a second microswitch 101, a second transmission member 109 and a second follower 108. The second microswitch 101 is engaged with the second transmission member 109 for transmission, and the second transmission member 109 is engaged with the second follower 108 for transmission, and the second follower 108 is connected to the main bonding conductor 3; the third drive coil 112 is used to drive the second microswitch 101 to move by generating magnetic force after being energized; wherein the second transmission assembly 100 is constructed to drive the second follower 108 to move through the second transmission member 109 when the second microswitch 101 moves, so that the main bonding conductor 3 is engaged with the corresponding output end.

[0315] Furthermore, the second micro switch 101 is configured to be rotatable around a fifth axis, and the second transmission member 109 is constructed to be rotatable around a sixth axis, and the fifth axis and the sixth axis are distributed vertically; the second micro switch 101 includes a second arc-shaped tooth portion 102 that rotates around the fifth axis, and the second transmission member 109 includes a third gear portion 110 that rotates around the sixth axis, and the second arc-shaped tooth portion 102 is engaged with the third gear portion 110 for transmission; the second transmission member 109 also includes a fourth gear portion 111 that rotates around the sixth axis, and the second follower 108 includes a second rack portion, and the fourth gear portion 111 is engaged with the second rack portion for transmission.

[0316] The following is based on Figure 6 、 Figures 45-55 The contactor of this embodiment will be described.

[0317] like Figure 47 As shown, the contactor according to the embodiment of the present invention includes: a first terminal 1 , a second terminal 2 , a main bonding conductor 3 , a second transmission assembly 100 and a third drive coil 112 .

[0318] Among them, such as Figure 45 As shown, one end of the contactor is provided with a first terminal 1 and a second terminal 2 at intervals, as shown in FIG. Figure 47 As shown, in a specific design, the first terminal 1 and the second terminal 2 can both be constructed as terminal posts, and the high-voltage wire can be connected to the terminal posts to achieve electrical connection with the contactor.

[0319] The main bonding conductor 3 is connected to the first terminal 1, that is, the first terminal 1 can be fixedly connected to the main bonding conductor 3, and the main bonding conductor 3 can be selectively attached to the second terminal 2. Therefore, by adjusting the main bonding conductor 3 of the contactor, the first terminal 1 and the second terminal 2 can be turned on and off, ensuring the convenience of switching the on and off state of the contactor. It should be noted that the first terminal 1 can be set as the input terminal and the second terminal 2 can be set as the output terminal, so that high voltage electricity can enter the contactor through the first terminal 1 and flow out of the contactor through the second terminal 2. Alternatively, the first terminal 1 can be set as the output terminal and the second terminal 2 can be set as the input terminal, so that high voltage electricity can enter the contactor through the second terminal 2 and flow out of the contactor through the first terminal 1.

[0320] like Figure 53 As shown, the second transmission assembly 100 includes a second microswitch 101, a second follower 108 and a second transmission member 109. The second microswitch 101, the second follower 108 and the second transmission member 109 are all provided with a tooth structure. The tooth structure of the second microswitch 101 is used to engage with the tooth structure of the second transmission member 109. When the second microswitch 101 moves, the second microswitch 101 can drive the second follower 108 to move through the tooth structure; the second follower 108 is arranged separately from the second microswitch 101, and the tooth structure of the second transmission member 109 engages with the tooth structure of the second follower 108. When the second microswitch 101 drives the second transmission member 109 to move, the second transmission member 109 can drive the second follower 108 to move through the tooth structure; the second follower 108 is fixedly connected to the movable end of the main bonding conductor 3. When the second follower 108 moves, the movable end of the main bonding conductor 3 can move together with the second follower 108.

[0321] It can be understood that by arranging a multi-stage gear transmission in the second transmission assembly 100, the movement transmitted from the second microswitch 101 to the main engaging conductor 3 can be changed during the transmission process, and the movement of the second microswitch 101 can be amplified or reduced, so that the second microswitch 101 has a larger stroke range, and the arrangement relationship between the second transmission assembly 100 and the main engaging conductor 3 is more flexible and diverse, thereby realizing the diversification of the overall layout of the contactor.

[0322] Among them, such as Figure 47As shown, the contactor includes a third drive coil 112, which has a cylindrical body. The wire is circumferentially wound around the outer wall of the cylindrical body, and the wire as a whole extends axially. When a low-voltage current is passed through the wire, the third drive coil 112 can generate a magnetic field. The second microswitch 101 is constructed to have a magnetic part. The magnetic field generated by the third drive coil 112 can act on the second microswitch 101, so that the third drive coil 112 can drive the second microswitch 101 to move.

[0323] When the second microswitch 101 moves, it can drive the second follower 108 to move via the second transmission member 109, so that the main engaging conductor 3 engages with the other of the first terminal 1 and the second terminal 2. It should be noted that when the second microswitch 101 moves in a first direction, it can drive the main engaging conductor 3 to engage with the second terminal 2, and when the second microswitch 101 moves in a second direction, it can drive the main engaging conductor 3 to disconnect from the other.

[0324] Specifically, a low-voltage current can be passed through the third drive coil 112 to generate a magnetic field, causing the second microswitch 101 to be forced to move in the first direction. At this time, the second microswitch 101 drives the main connecting conductor 3 to move through the second follower 108, so that the first terminal 1 and the second terminal 2 are electrically connected, allowing the contactor to conduct the high-voltage circuit. Alternatively, a reverse low-voltage current can be passed through the third drive coil 112 to generate a reverse magnetic field, causing the second microswitch 101 to be forced to move in the second direction. At this time, the second microswitch 101 drives the main connecting conductor 3 to move in the reverse direction through the second follower 108, so that the first terminal 1 and the second terminal 2 are electrically disconnected, allowing the contactor to disconnect the high-voltage circuit. In this way, convenient switching of the on / off state of the high-voltage circuit is achieved.

[0325] It can be understood that when a low-voltage current is passed through the third drive coil 112, the second microswitch 101 begins to move under force, and the second microswitch 101 drives the second transmission member 109 to move through the tooth structure, and the second transmission member 109 can drive the second follower 108 through the tooth structure. Through multi-stage gear transmission, the movement process of the second follower 108 is relatively smooth, so that the movement of the main bonding conductor 3 is smooth, thereby avoiding excessive acceleration of the main bonding conductor 3 and reducing the impact force of the main bonding conductor 3 during the bonding process.

[0326] According to the contactor of an embodiment of the present invention, a multi-stage gear transmission is set between the second microswitch 101 and the main engaging conductor 3 to amplify or reduce the movement of the second microswitch 101, so that the second microswitch 101 has a larger travel range, and when the third drive coil 112 drives the second microswitch 101, the movement process of the main engaging conductor 3 is smooth and stable, reducing the impact force when the main engaging conductor 3 is engaged, thereby reducing the closing noise and improving the stability of the contactor.

[0327] In some embodiments, as Figure 47 As shown, the second microswitch 101 is configured to rotate about a fifth axis, and the second transmission member 109 is configured to rotate about a sixth axis, with the fifth axis and the sixth axis being perpendicular to each other. The third drive coil 112 can drive the second microswitch 101 to rotate about the fifth axis in a first direction, or drive the second microswitch 101 to rotate about the fifth axis in a second direction. The first direction can be clockwise and the second direction can be counterclockwise, or the first direction can be counterclockwise and the second direction can be clockwise, so that the specific structure of the contactor can be flexibly arranged according to actual needs.

[0328] Through the above setting, the third drive coil 112 can drive the second microswitch 101 to rotate around the fifth axis. When the second microswitch 101 rotates around the fifth axis, it can drive the second transmission member 109 to rotate around the sixth axis perpendicular to the fifth axis. When the movement of the second microswitch 101 is transmitted to the second follower 108, the stroke range of the second follower 108 can be spatially staggered with the stroke range of the second microswitch 101, so as to efficiently utilize the space of the contactor, avoid the single-side size of the contactor being too large, and make the overall layout of the contactor more reasonable.

[0329] In some embodiments, as Figure 53 As shown, the second micro switch 101 includes a second arc-shaped tooth portion 102 rotating around a fifth axis, the second arc-shaped tooth portion 102 is constructed as a fan-shaped structure, and a tooth structure is provided on the side of the second arc-shaped tooth portion 102 away from the fifth axis, and the second transmission member 109 includes a third gear portion 110 rotating around a sixth axis, the third gear portion 110 can be constructed as a bevel gear portion or a spur gear portion, and the tooth structure of the third gear portion 110 corresponds to the tooth structure of the second arc-shaped tooth portion 102, so that the second arc-shaped tooth portion 102 can mesh with the third gear portion 110 to achieve transmission.

[0330] That is to say, if Figure 49As shown, when the third driving coil 112 drives the second arc-shaped tooth portion 102 to move around the fifth axis toward the first direction, the second arc-shaped tooth portion 102 can drive the third gear portion 110 to rotate around the sixth axis through the tooth structure, thereby driving the main connecting conductor 3 to move, so that the first terminal 1 and the second terminal 2 are connected; Figure 51 As shown, when the third driving coil 112 drives the second arc-shaped tooth portion 102 to move in the second direction around the fifth axis, the second arc-shaped tooth portion 102 can drive the third gear portion 110 to rotate around the sixth axis through the tooth structure, so as to drive the main connecting conductor 3 to move in the opposite direction, so that the first terminal 1 and the second terminal 2 are disconnected.

[0331] In some embodiments, as Figure 53 As shown, the second transmission member 109 also includes a fourth gear portion 111 that rotates around the sixth axis. The fourth gear portion 111 is constructed as a spur gear portion. The third gear portion 110 is directly connected to the end of the fourth gear portion 111, and the axes of the third gear portion 110 and the fourth gear portion 111 coincide with each other. The third gear portion 110 is used to drive the fourth gear portion 111 to rotate around the sixth axis. The second follower 108 includes a second rack portion, and the fourth gear portion 111 is engaged with the second rack portion through a tooth structure for transmission.

[0332] That is to say, if Figure 48 and Figure 49 As shown, when the third drive coil 112 drives the second arc-shaped tooth portion 102 to move around the fifth axis toward the first direction, the third gear portion 110 rotates around the sixth axis to drive the fourth gear portion 111 to rotate in the same direction. The fourth gear portion 111 drives the second rack portion to move through the tooth structure, thereby driving the main connecting conductor 3 to move, so that the first terminal 1 and the second terminal 2 are connected; as shown Figure 50 and Figure 51 As shown, when the third drive coil 112 drives the second arc-shaped tooth portion 102 to move in the second direction around the fifth axis, the third gear portion 110 rotates around the sixth axis to drive the fourth gear portion 111 to rotate in the same direction, and the fourth gear portion 111 drives the second rack portion to move in the opposite direction through the tooth structure, thereby driving the main connecting conductor 3 to move in the opposite direction, so that the first terminal 1 and the second terminal 2 are disconnected.

[0333] Through the above-mentioned arrangement, the rotation of the driving part 103 around the fifth axis is converted into the sliding of the second rack part along a fixed direction to drive the main connecting conductor 3 to move, thereby realizing the connection and disconnection of the first terminal 1 and the second terminal 2. At the same time, the sliding process is made smooth and stable, reducing the impact force when the main connecting conductor 3 is connected to the second terminal 2, thereby reducing the contact closure noise and improving the stability of the contactor.

[0334] In some embodiments, the diameter of the fourth gear portion 111 is greater than the diameter of the third gear portion 110. In other words, when the third gear portion 110 drives the fourth gear portion 111 to rotate, the rotational stroke of the fourth gear portion 111 is greater than the rotational stroke of the third gear portion 110. As a result, the stroke of the second microswitch 101 can be amplified by the second transmission member 109, reducing the stroke requirement of the second microswitch 101 during the switching process, facilitating the realization of a diverse layout of the entire contactor, and meeting the electrical clearance requirements of high voltage.

[0335] In some embodiments, the second rack portion is configured to extend vertically, and the upper end of the second rack portion is used to connect to the main bonding conductor 3, and the side wall of the lower end of the second rack portion is provided with a tooth structure that meshes with the fourth gear portion 111. Figure 47 As shown, the second rack portion is installed on one side of the fourth gear portion 111, and the lower end of the second rack portion is constructed as a columnar structure extending vertically. The lower end of the second rack portion is close to the side of the fourth gear portion 111 and is provided with a tooth structure extending vertically. The second rack portion can engage with the fourth gear portion 111 to transmit power.

[0336] Further, such as Figure 47 As shown, the upper end of the second rack portion is constructed as a columnar structure extending in the horizontal direction, so that the second rack portion as a whole is constructed into a T-shaped structure. The upper end of the second rack portion has a snap-fit groove open toward the main bonding conductor 3, and the end of the main bonding conductor 3 can extend into the snap-fit groove.

[0337] Thus, when the third drive coil 112 drives the second arc-shaped tooth portion 102 to move in the first direction around the fifth axis, the fourth gear portion 111 drives the second rack portion to move through the tooth structure, so as to drive the main connecting conductor 3 to move in the same direction, so that the first terminal 1 and the second terminal 2 are connected; and when the third drive coil 112 drives the second arc-shaped tooth portion 102 to move in the second direction around the fifth axis, the fourth gear portion 111 drives the second rack portion to move in the opposite direction through the tooth structure, so as to drive the main connecting conductor 3 to move in the opposite direction, so that the first terminal 1 and the second terminal 2 are disconnected.

[0338] In a specific processing process, the upper end and the lower end of the second rack portion can be processed separately, and after the processing is completed, the upper end and the lower end of the second rack portion are connected and fixed together to reduce the processing difficulty of the second rack portion.

[0339] Specifically, the first terminal 1 and the second terminal 2 can be arranged at the same height, and the end of the main bonding conductor 3 away from the second rack portion is extended to the lower side of the first terminal 1, so that the upper side of the main bonding conductor 3 is fitted and connected to the lower side of the first terminal 1, and at the same time, the end of the main bonding conductor 3 close to the second rack portion is extended into the card interface, so that the second rack portion can limit the main bonding conductor 3. When the second rack portion moves, the second rack portion can drive the main bonding conductor 3 to move in the same direction. The second terminal 2 is arranged above the side of the main bonding conductor 3 close to the second rack portion, as shown in FIG. Figure 48 As shown, when the main bonding conductor 3 moves to the upper limit position (ie, the vertical maximum position), the main bonding conductor 3 is connected to the second terminal 2, as shown in FIG. Figure 50 As shown, when the second rack portion drives the main bonding conductor 3 to move downward, the main bonding conductor 3 is disconnected from the second terminal 2, so that the first terminal 1 and the second terminal 2 are electrically disconnected.

[0340] Therefore, the side surfaces of the main bonding conductor 3 can be used to fit on the side surfaces of the first terminal 1 and the second terminal 2 to serve as moving contacts, thereby reducing the number of moving contacts and providing the moving contacts with sufficient bonding area to reduce the contact resistance of the moving contacts, thereby reducing the heat generation of the contactor, reducing energy loss, and reducing the possibility of adhesion of the moving contacts.

[0341] Further, such as Figure 47 As shown, by sequentially arranging the main bonding conductor 3 and the third driving coil 112 in the vertical direction, and making the third driving coil 112 and the second micro switch 101 in the horizontal direction ( Figure 47 The left and right directions in the figure are arranged opposite each other, so that the overall layout of the contactor is uniform, which is conducive to overall heat dissipation.

[0342] In another embodiment, the second rack portion is constructed to extend laterally, and one end of the second rack portion is used to be connected to the main bonding conductor 3, and the side wall of the other end of the second rack portion is provided with a tooth structure that engages with the fourth gear portion 111, the first terminal 1 and the second terminal 2 are respectively arranged opposite to the main bonding conductor 3 in the first direction, the third drive coil 112 and the second micro switch 101 are respectively arranged opposite to each other in the first direction, the first terminal 1 and the second terminal 2 are respectively arranged opposite to the third drive coil 112 in the second direction, the main bonding conductor 3 and the second micro switch 101 are respectively arranged opposite to each other in the second direction, wherein the first direction and the second direction are orthogonal.

[0343] That is to say, if Figure 55As shown, the second rack is mounted above the fourth gear portion 111. The second rack is constructed as a horizontally extending columnar structure. Its underside is provided with a tooth structure extending along its length. The second rack engages with the fourth gear portion 111, thereby transmitting power. Furthermore, the main bonding conductor 3 is vertically disposed at one end of the second rack, with the end of the second rack pressing against the sidewall of the main bonding conductor 3.

[0344] Furthermore, when the third driving coil 112 drives the second micro switch 101 to move around the fifth axis toward the first direction, the second rack portion pushes the main bonding conductor 3 toward the direction close to the output end ( Figure 55 ) and when the main bonding conductor 3 extends as a whole along the axial direction of the third driving coil, the main bonding conductor 3 is connected to the output end 2, so that the input end 1 and the output end 2 are connected; and when the third driving coil 112 drives the second micro switch 101 to move in the second direction around the fifth axis, the second rack portion pushes the main bonding conductor 3 toward a direction away from the output end ( Figure 55 The left side of the main connecting conductor 3 moves so that the main connecting conductor 3 is separated from the output terminal 2, so that the input terminal 1 and the output terminal 2 are disconnected, thereby realizing the switching of the on-off state of the high-voltage line.

[0345] In some embodiments, as Figure 53 As shown, the main bonding conductor 3 includes a fixed portion 31 and a bonding portion 33. The fixed portion 31 is fixedly connected to the first terminal 1, and the second follower 108 is connected to the bonding portion 33 to drive the bonding portion 33 to engage with the second terminal 2. It should be noted that the material of the main bonding conductor 3 can be a composite material such as soft copper (silver), which provides the main bonding conductor 3 with a greater current carrying capacity and further reduces the resistance of the main bonding conductor 3. At the same time, the hardness of the main bonding conductor 3 is reduced, thereby reducing noise during the bonding process between the second terminal 2 and the main bonding conductor 3.

[0346] It is understandable that when the second micro switch 101 rotates about the fifth axis toward the first direction, the second rack portion moves downward, and the second rack portion applies a downward force to the joint portion 33, causing the joint portion 33 to move downward, thereby disconnecting the main joint conductor 3 from the second terminal 2; and when the second micro switch 101 rotates about the fifth axis toward the second direction, the second rack portion moves upward, thereby driving the joint portion 33 to move upward, thereby engaging the second terminal 2 and the joint portion 33. In this way, convenient switching of the on / off state of the high-voltage line is achieved.

[0347] In some embodiments, a weakened portion 32 is connected between the fixed portion 31 and the engaging portion 33. That is, when the second rack portion moves downward, it applies a downward force to the engaging portion 33, causing the weakened portion 32 to elastically deform. The fixed portion 31 and the engaging portion 33 move relative to each other, disconnecting the main engaging conductor 3 from the second output terminal 2. When the second microswitch 101 rotates about the fifth axis in the second direction, the second rack portion moves upward, restoring the elastic deformation of the weakened portion 32, and engaging the second output terminal 2 with the engaging portion 33.

[0348] Therefore, by providing the weakened portion 32, relative movement between the fixing portion 31 and the joining portion 33 is achieved, and plastic deformation of the joining portion 33 is avoided, so that the joining portion 33 can be repeatedly attached to the side of the second terminal 2, thereby improving the stability and reliability of the contactor.

[0349] In some embodiments, the weakened portion 32 is constructed as an arc segment, one end of the arc segment is connected to the fixing portion 31 and the other end is connected to the joint portion 33, and a weakened cavity 321 is defined in the weakened portion 32. Figure 47 As shown, the weakened portion 32 can be constructed as a downwardly protruding semicircular arc segment, the left end of the weakened portion 32 is connected to the fixing portion 31 , and the right end of the weakened portion 32 is connected to the joining portion 33 to jointly construct the main joining conductor 3 .

[0350] Furthermore, when the second follower 108 applies a downward force to the engaging portion 33, the weakened portion 32 compresses and deforms, causing relative movement between the fixed portion 31 and the engaging portion 33, disconnecting the main engaging conductor 3 from the second terminal 2. When the second follower 108 moves upward, the elastic deformation of the weakened portion 32 recovers, and the second terminal 2 and the engaging portion 33 engage. The provision of an arc-shaped weakening cavity 321 within the weakened portion 32 further reduces the overall stiffness of the weakened portion 32, making it easier for the weakened portion 32 to elastically deform when subjected to the force transmitted by the engaging portion 33, thereby reducing the size requirements of the third drive coil 112.

[0351] In some embodiments, the second micro switch 101 includes a driving portion 103 that rotates around a fifth axis. The driving portion 103 is spaced apart and arranged horizontally outside the third driving coil 112. The first end of the driving portion 103 (e.g., Figure 54 The left end of the driving part 103 is provided with a first magnetic part 104 and a second magnetic part 105 which are relatively distributed. Figure 54 A third magnetic portion 106 and a fourth magnetic portion 107 are provided at the right end thereof so as to configure the driving portion 103 into an I-shaped structure.

[0352] Among them, such as Figure 47As shown, the third driving coil 112 includes a coil body, a first magnetic conductive sheet 113 and a second magnetic conductive sheet 114, one end of the first magnetic conductive sheet 113 is connected to one end of the coil body, and the other end of the first magnetic conductive sheet 113 extends between the first magnetic part 104 and the second magnetic part 105, one end of the second magnetic conductive sheet 114 is connected to the other end of the coil body, and the other end of the second magnetic conductive sheet 114 extends between the third magnetic part 106 and the fourth magnetic part 107.

[0353] That is to say, the coil body is extended in the longitudinal direction, and the first magnetic conductive sheet 113 and the second magnetic conductive sheet 114 are fitted and connected at the two ends of the coil body. The main parts of the first magnetic conductive sheet 113 and the second magnetic conductive sheet 114 are fitted opposite to the ends of the third driving coil 112, and a folding plate is connected to the side of the main part close to the driving part 103. The folding plate is extended along the axis of the third driving coil 112, and the folding plate of the first magnetic conductive sheet 113 extends between the first magnetic part 104 and the second magnetic part 105, and the folding plate of the first magnetic conductive sheet 113 extends between the first magnetic part 104 and the second magnetic part 105.

[0354] Therefore, by setting the first magnetic conductive sheet 113 and the second magnetic conductive sheet 114, the third drive coil 112 can simultaneously drive both ends of the second micro switch 101 to drive the second micro switch 101 to rotate stably around the fifth axis, thereby realizing stable switching of the on and off states of the high-voltage line, and reducing the size requirements for the third drive coil 112, reducing costs, and facilitating the overall layout of the contactor.

[0355] In some embodiments, the first magnetic portion 104, the second magnetic portion 105, the third magnetic portion 106, and the fourth magnetic portion 107 are all permanent magnets, wherein the first magnetic portion 104 and the second magnetic portion 105 have opposite polarities, the third magnetic portion 106 and the fourth magnetic portion 107 have opposite polarities, and the first magnetic conductive sheet 113 and the second magnetic conductive sheet 114 have opposite polarities. It should be noted that the magnetic portions located on the same side have the same polarity, such as the first magnetic portion 104 and the third magnetic portion 106 have the same magnetic properties, and when a low-voltage current is applied to the third drive coil 112, the first magnetic conductive sheet 113 and the second magnetic conductive sheet 114 can generate different polarities, thereby driving the drive portion 103 to rotate about the fifth axis.

[0356] Specifically, the inner sides of the first magnetic portion 104 and the third magnetic portion 106 can be set as N poles, and the inner sides of the second magnetic portion 105 and the fourth magnetic portion 107 can be set as S poles. When the third driving coil 112 is supplied with a positive low-voltage current, the first magnetic conductive sheet 113 is the N pole and the second magnetic conductive sheet 114 is the S pole. At this time, Figure 49As shown, the first magnetic portion 104 and the second magnetic portion 105 work together to make the first magnetic conductive sheet 113 fit on the inner side wall of the second magnetic portion 105, and at the same time, the third magnetic portion 106 and the fourth magnetic portion 107 work together to make the second magnetic conductive sheet 114 fit on the inner side wall of the third magnetic portion 106, so as to drive the second rack portion to move upward, thereby realizing the connection between the first terminal 1 and the second terminal 2; and when the third driving coil 112 is supplied with a reverse low-voltage current, the first magnetic conductive sheet 113 is the S pole and the second magnetic conductive sheet 114 is the N pole. At this time, as shown in FIG. Figure 51 As shown, the first magnetic part 104 and the second magnetic part 105 work together to make the first magnetic conductive sheet 113 adhere to the inner wall of the first magnetic part 104, and at the same time, the third magnetic part 106 and the fourth magnetic part 107 work together to make the second magnetic conductive sheet 114 adhere to the inner wall of the fourth magnetic part 107, so as to drive the second follower 108 to move downward, thereby disconnecting the connection between the first terminal 1 and the second terminal 2.

[0357] Through the above arrangement, when the third drive coil 112 is energized, the first end and the second end of the drive unit 103 can be subjected to forces in opposite directions, so that the drive unit 103 can rotate stably around the fifth axis, thereby driving the main bonding conductor 3 to move, thereby realizing stable switching of the on and off states of the high-voltage line.

[0358] In some embodiments, as Figure 45 As shown, the contactor of the embodiment of the present invention further includes a housing 206. The first terminal 1 and the second terminal 2 are mounted on the housing 206. The main bonding conductor 3, the second transmission assembly 100, the first, third, and second third drive coils 112 are all mounted within the housing 206. The second follower 108 is in sliding engagement with the inner circumferential wall of the housing 206.

[0359] That is to say, if Figure 45 As shown, the overall structure of housing 206 is rectangular. Outwardly protruding legs 76 are provided at opposite corners of housing 206. Legs 76 have mounting holes 72 extending through the thickness of the housing. Connectors can be inserted through mounting holes 72 to secure the contactor. The external structure of housing 206 is consistent with that of traditional contactors, facilitating structural design and material switching. It should be noted that the sidewalls of housing 206 have openings through which low-voltage signal lines can pass through housing 206 to electrically connect to an external power source, allowing operators to control the on / off of the contactor using an external switch. The low-voltage signal lines can also be designed as connectors.

[0360] Furthermore, if Figure 46As shown, the housing 206 has an outwardly open cavity structure, with a cover structure 73 provided at the open end. The cover structure 73 has through-holes corresponding to the first terminal 1 and the second terminal 2. The upper portions of the first terminal 1 and the second terminal 2 can extend into the through-holes to be mounted on the cover structure 73, thereby maintaining relative stability with the housing 206, allowing the main connecting conductor 3 to move relative to the second terminal 2. The remaining portions of the first terminal 1 and the second terminal 2, as well as the main connecting conductor 3, the second transmission assembly 100, and the third drive coil 112 are all sealed within the housing 206 by the cover structure 73, thereby being isolated from the outside world to prevent external impurities from entering the housing 206 and providing insulation protection. At the same time, the inner peripheral wall of the housing 206 can limit the second follower 108, allowing the second follower 108 to slide in the same direction relative to the inner peripheral wall, thereby ensuring a stable movement path of the main connecting conductor 3 and improving the reliability of the contactor operation process.

[0361] In some embodiments, the inner peripheral wall of the housing 206 is provided with a sliding guide groove 74, and the second rack portion of the second follower 108 is slidably engaged with the sliding guide groove 74. Figure 52 As shown, the sliding guide groove 74 is extended in the height direction, and the opening size of the sliding guide groove 74 is equal to the width size of the lower end of the second rack portion. When the second rack portion is installed in the sliding guide groove 74, the sliding guide groove 74 can limit the second rack portion so that the second rack portion can move back and forth vertically, thereby ensuring that the contact and disengagement process between the main bonding conductor 3 and the first terminal 1 is reliable, thereby improving the stability of the contactor.

[0362] In some embodiments, the contactor of the embodiment of the present invention further includes: a temperature sensor and a controller, the temperature sensor being electrically connected to the controller, and the temperature sensor being used to detect circuit signals of the first terminal 1, the second terminal 2, and / or the main bonding conductor 3, and the controller being used to control the main bonding conductor 3 to engage or disconnect with the second terminal 2 according to the circuit signals, wherein the circuit signals include: temperature changes, voltage changes, and current changes. In other words, a temperature sensor can be provided to monitor the main bonding conductor 3, or a temperature sensor can be provided to detect the first terminal 1 and the second terminal 2, or a temperature sensor can be provided to detect the first terminal 1, the second terminal 2, and the main bonding conductor 3 simultaneously, thereby obtaining temperature changes, voltage changes, and current changes of the high-voltage line.

[0363] It can be understood that as the first terminal 1 and the second terminal 2 are connected through the main bonding conductor 3, the current and heat generation of the high-voltage line will change, and corresponding temperature changes will occur. The temperature sensor can obtain the change information of the high-voltage line during operation (including temperature changes, voltage changes and current changes), and transmit it to the controller in the form of a circuit signal. The controller determines whether the cut-off threshold of the high-voltage line is reached based on the circuit signal, and when the high-voltage circuit needs to be disconnected, the controller controls the drive component to disconnect the electrical connection between the second terminal 2 and the main bonding conductor 3. Not only does it not need to set a fuse to reduce high-voltage loss, but it also reduces costs.

[0364] After controlling the contactor to disconnect, if the electrical equipment using the contactor of the present invention needs to continue operating, the controller can use the drive assembly to connect the second terminal 2 with the main connecting conductor 3 to ensure that the electrical equipment can be supplied with high voltage, thereby improving safety. For example, if the contactor of the present invention is used in an electric vehicle and circuit information indicates that the contactor needs to be disconnected but the vehicle is in a dangerous situation and needs to maintain operating conditions, the high voltage state can be maintained. After the vehicle reaches a safe location or the dangerous situation is resolved, the electrical connection between the second terminal 2 and the main connecting conductor 3 can be disconnected.

[0365] In some embodiments, as Figure 6 As shown, the charging and distribution system 1000 according to the embodiment of the present invention includes: the contactors in the above embodiment, the contactors are constructed as a main positive contactor 100a, a main negative contactor 100b and a pre-charging contactor 100c.

[0366] Specifically, the charging and distribution system 1000 includes: a battery end interface, an electronic control end interface, and a DC charging interface. The DC charging interface and the electronic control end interface are arranged at the same end of the contactor housing, and the battery end interface is arranged at the other end of the housing. A main positive contactor 100a is provided on the positive side of the DC charging interface and the positive side of the battery end interface, and a main negative contactor 100b is provided on the negative side of the DC charging interface and the negative side of the battery end interface. A pre-charging circuit is also provided on the positive side of the battery end interface. A pre-charging contactor 100c is provided on the pre-charging circuit in series with a pre-charging resistor and in parallel with the main positive contactor 100a.

[0367] According to an embodiment of the present invention, the charging and distribution system 1000 uses the above-mentioned contactor. By providing a multi-stage gear transmission between the second microswitch 101 and the main engaging conductor 3, the movement of the second microswitch 101 is amplified or reduced. This allows the second microswitch 101 to have a larger travel range. When the third drive coil 112 drives the second microswitch 101, the movement of the main engaging conductor 3 is smooth and stable, reducing the impact force when the main engaging conductor 3 engages, thereby reducing closing noise and improving the stability of the contactor. This can extend the operating stability, safety, and service life of the charging and distribution system 1000.

[0368] like Figure 6 、 Figures 56-67 As shown, according to the power distributor 2000 of the embodiment of the present invention, the fourth contactor K4 and / or the fifth contactor K5 include: a driving device 40, a coupling bar 30, the coupling bar 30 including a first conductive segment 301 and a second conductive segment 302, the first conductive segment 301 and the second conductive segment 302 being interconnected and rotatable relative to each other, the first conductive segment 301 being fixed to the corresponding input terminal, and the second conductive segment 301 being selectively electrically connected to or disconnected from the corresponding output terminal; the driving device 40 is configured to drive the second conductive segment 302 toward or away from the output terminal; wherein the input terminal and the output terminal are respectively arranged relative to the coupling bar 30 in a third direction, and at least one of the coupling bar 30, the input terminal, and the output terminal is arranged relative to the driving device 40 in a fourth direction, the third direction being orthogonal to the fourth direction. This arrangement allows selective connection between the input terminal and the output terminal.

[0369] Furthermore, the driving device 40 includes: a third microswitch 402 and a fourth driving coil 401. The third microswitch 402 and the fourth driving coil 401 are arranged relative to each other in the third direction. The third microswitch 402 is suitable for swinging around a fixed axis under the action of the magnetic force of the fourth driving coil 401. The third microswitch 402 is used to drive the second conductive section 302 to move toward or away from the output end. The fourth driving coil 401 is arranged relative to the input end and the output end in the fourth direction. The third microswitch 402 is arranged relative to the joint electrode 30 in the fourth direction.

[0370] Furthermore, the third micro switch 402 includes: a driving platform 403 and a connecting frame 404, one end of the connecting frame 404 is connected to the driving platform 403, and the other end of the connecting frame 404 is connected to the second conductive section 302, and the driving platform 403 is suitable for swinging under the action of the magnetic force of the fourth driving coil 401. The driving platform 403 is used to drive the connecting frame 404 to swing, thereby driving the second conductive section 302 to move toward or away from the output end.

[0371] The following is based on Figure 6 、 Figures 56-67The contactor of this embodiment will be described in detail.

[0372] like Figures 57-60 、 Figure 63 As shown, the contactor according to the embodiment of the present invention includes: a first terminal 1 and a second terminal 2 , a connecting electrode 30 , and a driving device 40 .

[0373] Among them, the joining electric bus 30 includes: a first conductive segment 301 and a second conductive segment 302, the first conductive segment 301 and the second conductive segment 302 are connected to each other and can rotate relative to each other, the first conductive segment 301 is fixed on the first terminal 1, and the second conductive segment 302 can be selectively electrically connected to or disconnected from the second terminal 2; the driving device 40 is used to drive the second conductive segment 302 to move toward or away from the second terminal 2, the first terminal 1 and the second terminal 2 are respectively arranged relative to the joining electric bus 30 in the third direction, and at least one of the joining electric bus 30, the first terminal 20 and the first terminal 1 is arranged relative to the driving device 40 in the fourth direction, and the third direction is orthogonal to the fourth direction.

[0374] Specifically, the first terminal 1 and the second terminal 2 can be selectively electrically connected or disconnected through the engaging electrical bus 30, and the driving device 40 is used to drive the engaging electrical bus 30 to move between the first position and the second position to realize the conduction and disconnection of the first terminal 1 and the second terminal 2, that is, the first position corresponds to the position where the first terminal 1 and the second terminal 2 are conductive, and the second position corresponds to the position where the first terminal 1 and the second terminal 2 are disconnected.

[0375] It should be noted that the relative rotation of the first conductive section 301 and the second conductive section 302 means that the two can be connected by a conductive rotating connection structure to achieve relative rotation, or they can be connected by a flexible structural member (i.e., at least a portion of the connecting rod 30 is constructed as a flexible structure) and relative rotation is achieved by bending the flexible structure. Alternatively, the connecting rod 30 can be constructed as an entire flexible member and relative rotation is achieved by bending. With this structure, when the second conductive section 302 rotates, the connecting rod 30 is subjected to less bending wear, which can extend the service life of the connecting rod 30 and thus improve the service life of the contactor.

[0376] Furthermore, see Figure 57 and Figure 59 As shown, the joining bar 30 is arranged relative to the first terminal 1 and the second terminal 2 in the third direction, and the joining bar 30 and the driving device 40 are arranged relative to each other in the fourth direction. For example, the third direction corresponds to the length direction or width direction on the horizontal plane, and the fourth direction corresponds to the height direction. The first terminal 1, the second terminal 2 and the joining bar 30 are arranged at the same height, and the driving device 40 is located above or below the joining bar 30 to reduce the size of the contactor in the height direction.

[0377] According to the contactor of the embodiment of the present invention, by arranging the connecting electrode 30, the first terminal 1, and the second terminal 2 relative to each other in the third direction, and arranging the driving device 40 and the connecting electrode 30 relative to each other in the fourth direction, the space occupied by the contactor can be improved, the overall length of the contactor can be shortened, the overall structural strength of the contactor can be improved, and the probability of the contactor being easily broken from the middle area in an environment where it is subjected to long-term vibration such as when used in a vehicle 10000 is reduced, thereby extending the service life of the contactor.

[0378] In addition, through the above-mentioned settings, the contactor can be layered and isolated from high and low voltages (the upper layer is the high-voltage conduction part and the lower layer is the low-voltage control part), so that the arc extinguishing method is no longer limited to the combination of inert gas and magnetic blowing arc extinguishing. It can also be achieved by overall infiltration of insulating liquid or no arc extinguishing structure is set. Based on the diversity of arc extinguishing methods, there is no need to insulate the drive device 40 from the chamber, which can solve the low-voltage failure problem. There is no need to inject inert gas, and there is no need to use ceramic and metal brazing technology to process the contactor. It can also simplify the processing technology of the contactor, reduce material processes, improve production efficiency, and reduce the processing cost of the contactor.

[0379] The first terminal 1 is fixed to the first conductive section 301, and the second terminal 2 is selectively electrically connected to the second conductive section 302. This can also reduce the number of moving contacts, reduce the high-voltage power consumption problem caused by the moving contacts, reduce the number of arcs, reduce adhesion points, and reduce the wear and tear generated by the contactor during circuit control. In summary, it reduces risk points and power loss.

[0380] Among them, during the operation of the contactor, the second conductive section 302 will collide with the second terminal 2, generating operating noise. In order to reduce the operating noise of the contactor, the bonding bus 30 of the present invention can be 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. At the same time, the use of flexible metal materials can increase the current and reduce the contact resistance between the second terminal 2 and the bonding bus 30, thereby reducing the probability of adhesion between the two.

[0381] like Figure 61 and Figure 62As shown, according to some embodiments of the present invention, the driving device 40 includes: a third microswitch 402 and a fourth driving coil 401. The third microswitch 402 and the fourth driving coil 401 are arranged relative to each other in the third direction. The third microswitch 402 is suitable for swinging around a fixed axis under the action of the magnetic force of the fourth driving coil 401. The third microswitch is used to drive the second conductive section 302 toward or away from the second terminal 2 by the magnetic force. The fourth driving coil 401 is arranged relative to the first terminal 1 and the second terminal 2 in the fourth direction. The third microswitch 402 is arranged relative to the joint electrode 30 in the fourth direction.

[0382] Specifically, the third microswitch 402 and the fourth drive coil 401 are arranged relative to each other in the third direction. The fourth drive coil 401 generates a magnetic force that can drive the third microswitch 402 to rotate around a fixed axis. The third microswitch 402 is connected to the connecting electrode 30 and is arranged relative to each other in the fourth direction to facilitate driving the connecting electrode 30 to move. The first terminal 1 and the second terminal 2 are both located above or below the fourth drive coil 401, thereby facilitating the high and low voltage isolation between the low-voltage control part and the high-voltage conduction part.

[0383] like Figures 61-64 As shown, the third micro switch 402 includes: a driving platform 403 and a connecting frame 404, one end of the connecting frame 404 is connected to the driving platform 403, and the other end of the connecting frame 404 is connected to the second conductive section 302, the driving platform 422 is suitable for swinging under the action of the magnetic force of the fourth driving coil 401, and the driving platform 403 is used to drive the connecting frame 404 to swing, thereby driving the second conductive section 42 to move toward or away from the second terminal 2.

[0384] That is to say, the third micro switch 402 is rotated around the fixed axis by cooperating with the driving platform 403 and the fourth driving coil 401, and a connecting frame 404 is provided above the driving platform 403. The connecting frame 404 and the driving platform 403 are integrally formed or fixedly connected. The driving platform 403 can rotate synchronously with the connecting frame 404. The connecting frame 404 is connected to the second conductive section 302 to drive the second conductive section 302 to swing relative to the first conductive section 301, thereby improving the movement stability of the joint electrode 30.

[0385] Preferably, the connection area between the first conductive section 301 and the second conductive section 302 is arranged relative to the driving platform 403 in the fourth direction, so that the driving platform 403 and the first conductive section 32 can swing more synchronously, which can improve the control accuracy, and the arrangement of the contactor is more compact, which can improve the integration of the contactor.

[0386] In some embodiments, the connection area between the first conductive segment 301 and the second conductive segment 302 is arranged relative to the rotation center of the third micro switch 402 in the fourth direction, that is, the swing center of the second conductive segment 302 is coaxial with the rotation center of the driving platform 403 (that is, the rotation center of the third micro switch 402), further improving the motion synchronization, control accuracy, and structural integration of the two.

[0387] In some embodiments, the other end of the connecting frame 404 is connected to the end of the second conductive segment 22 away from the first conductive segment 21 , or the other end of the connecting frame 404 is connected to the other end of the second conductive segment 22 close to the first conductive segment 21 .

[0388] That is to say, in some embodiments, the connecting frame 404 drives the second conductive segment 22 to move toward or away from the second terminal 2 by connecting to the end of the second conductive segment 22 away from the first conductive segment 21. In other embodiments, the connecting frame 404 drives the second conductive segment 22 to move toward or away from the second terminal 2 by connecting to the end of the second conductive segment 22 close to the first conductive segment 21.

[0389] In some embodiments, the other end of the connecting frame 404 is formed as a clamping portion 406. Figure 61 and Figure 62 In the first embodiment shown, the clamping portion 406 clamps the end of the second conductive section 302 away from the first conductive section 301 to effectively amplify the stroke of the third micro switch 402; or Figure 63 and Figure 64 In the second embodiment shown, the clamping portion 406 clamps the other end of the second conductive section 302, which is closer to the first conductive section 301. Compared to the first embodiment, the lengths of the connecting frame 404 at both ends can be shortened in the second embodiment, making the connecting frame 404 smaller and facilitating a lightweight and compact design of the contactor.

[0390] like Figure 61 and Figure 62 As shown, permanent magnets 405 are provided on the four corner areas of the driving platform 403, and magnetic conductive sheets are provided at both ends of the fourth driving coil 401. The magnetic conductive sheet at one end of the fourth driving coil 401 is suitable for attracting the two permanent magnets at one end of the driving platform 403, and the magnetic conductive sheet at the other end of the fourth driving coil 401 is suitable for attracting the two permanent magnets at the other end of the driving platform 403. The polarities of the two permanent magnets 405 located at the same end of the driving platform 403 are opposite.

[0391] It can be understood that after the fourth drive coil 401 is energized, the polarities of the magnetic conductive sheets at both ends are different, and the polarities of the two permanent magnets 405 located at the same end of the fourth drive coil 401 are different, so that one end of the drive platform 403 can move toward the fourth drive coil 401, and the other end can move away from the fourth drive coil 401.

[0392] Of course, the structure of the present invention is not limited to this. Two permanent magnets 405 can also be set at only one end of the driving platform 403, or one permanent magnet 405 can be set at each end, so that the permanent magnets 405 are located in the corner areas respectively, and the third micro switch 402 can be driven to rotate under the action of polar attraction or polar repulsion.

[0393] In this way, by setting the permanent magnet 405, the working state of the contactor can be maintained by the magnetic attraction of the permanent magnet 405, that is, it stays in the first position or the second position, and the fourth drive coil 401 of the low-voltage control part does not need to be continuously energized to reduce low-voltage loss and improve the energy consumption ratio of the contactor.

[0394] exist Figure 58 In the specific embodiment shown, the distance between the free end of the permanent magnet 405 and the rotation center of the third micro switch 402 is smaller than the distance between the contact point between the second terminal 2 and the second conductive section 302 and the rotation center of the third micro switch 402 .

[0395] That is, the distance between one end of the permanent magnet 405 and the rotation center of the third microswitch 402 is L1; the distance between the contact point between the second terminal 2 and the second conductive segment 302 and the rotation center of the third microswitch 402 is L2, where L1 < L2. This increases the travel of the second conductive segment 22 relative to the third microswitch 33, thereby increasing the travel of the third microswitch 402 to meet the electrical clearance requirements of the high-voltage circuit to which the contactor is connected.

[0396] like Figure 64As shown, in a specific embodiment, the driving device 40 also includes a rotating shaft, the driving platform 403 is connected to the rotating shaft and is suitable for rotating around the rotating shaft; the permanent magnet 405 includes a first magnetic pole, a second magnetic pole, a third magnetic pole and a fourth magnetic pole, the first magnetic pole has opposite polarity to the second magnetic pole and is spaced apart at one end of the driving platform 403, the third magnetic pole has opposite polarity to the fourth magnetic pole and is spaced apart at the other end of the driving platform 403, the first magnetic pole and the third magnetic pole have the same polarity and are arranged close to the fourth driving coil 401, and the second magnetic pole and the fourth magnetic pole have the same polarity and are arranged away from the fourth driving coil 401; the magnetic conductive sheet includes a first magnetic conductive sheet and a second magnetic conductive sheet, one end of the first magnetic conductive sheet is connected to one end of the fourth driving coil 401, and the other end of the first magnetic conductive sheet is arranged between the first magnetic pole and the second magnetic pole, one end of the second magnetic conductive sheet is connected to the other end of the fourth driving coil 401, and the other end of the second magnetic conductive sheet is arranged between the third magnetic pole and the fourth magnetic pole.

[0397] Exemplarily, the first magnetic pole is the N pole, the second magnetic pole is the S pole, the third magnetic pole is the N pole, and the fourth magnetic pole is the S pole. The first magnetic pole and the second magnetic pole are arranged at the same end of the driving platform 403, and the third magnetic pole and the fourth magnetic pole are arranged at the other end of the driving platform 403. When the fourth driving coil 401 is energized in the first current direction, the first magnetic pole is magnetically attracted to the first magnetic conductive sheet, and the third magnetic pole is magnetically attracted to the second magnetic conductive sheet. When the fourth driving coil is energized in the second current direction, the second magnetic pole is magnetically attracted to the first magnetic conductive sheet, and the fourth magnetic pole is magnetically attracted to the second magnetic conductive sheet. The first current direction is opposite to the second current direction.

[0398] Furthermore, the driving platform 403 is constructed as an insulating member or coated with an insulating layer. In this way, the second conducting section 302 is arranged on the connecting frame 404. The corresponding driving platform 403 is an insulating member or coated with an insulating layer, which can improve the high-voltage and low-voltage isolation between the high-voltage conducting part and the low-voltage control part, avoid high-voltage breakdown causing low-voltage failure, and improve the operating stability of the contactor.

[0399] like Figure 58 and Figure 60 As shown, according to some embodiments of the present invention, the joint electrical bus 30 further includes: a flexible connection portion 303, the flexible connection portion 303 connecting the first conductive segment 301 and the second conductive segment 302, and located between the first conductive segment 301 and the second conductive segment 302, and the second conductive segment 302 can swing relative to the flexible connection portion 303 to move toward or away from the second terminal 2.

[0400] Specifically, the two ends of the flexible connection portion 303 are connected to the first conductive section 301 and the second conductive section 302 respectively. The flexible connection portion 303 can be bent so that the second conductive section 302 can move toward or away from the second terminal 2, thereby improving the convenience of switching the contactor between the first position and the second position. By setting the flexible connection portion 303, the bending wear of the connecting electrode 30 can be reduced, thereby extending the service life of the connecting electrode 30 and thereby improving the service life of the contactor.

[0401] Furthermore, an arcuate slot 331 is defined within the flexible connection portion 303, extending through the flexible connection portion 303 along the height of the junction bus 30. This gap allows the arcuate slot 331 to deform and absorb some of the bending deformation during the bending process of the flexible connection portion 303, further reducing bending wear of the flexible connection portion 303 and effectively extending the service life of the junction bus 30.

[0402] like Figure 65 As shown, in some embodiments, the contactor further includes: a sensor 70, which is arranged near the first terminal 1 or the second terminal 2 or the joint electric bus 30 and is used to detect the circuit signal of the first terminal 1 or the second terminal 2 or the joint electric bus 30 in real time; a controller, which is electrically connected to the sensor 70 and is suitable for controlling the drive device 40 to open or close the contactor according to the circuit signal.

[0403] In this way, by setting up a controller and a sensor 70, as the first terminal 1 and the second terminal 2 are connected through the connecting electrode 30, the current and heat generation of the high-voltage circuit will change, and corresponding temperature changes will occur. The sensor 70 can obtain the change information (temperature change, current change, etc.) during the operation of the high-voltage circuit and transmit it to the 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, the controller controls the drive device 40 to disconnect the electrical connection between the second end 32 and the second terminal 2. Not only does it not need to set up a fuse to reduce high-voltage loss and reduce costs, but after controlling the disconnection of the contactor, if the electrical equipment using the contactor 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.

[0404] Specifically, if Figure 67 As shown in the figure, the conversion principle between a thermistor and its corresponding voltage is: V = (NTC / (NTC+R)) × VCC; where V is the input voltage, VCC is the standard voltage, R is the fixed resistor, and NTC is the thermistor. Therefore, the circuit signal AD is calculated as: AD = (V / VCC) × 2n = (NTC / (NTC+R)) × 2n.

[0405] In this way, by obtaining the voltage value of the thermistor, the required circuit signal can be converted.

[0406] It should be pointed out that after the fuse blows, the high-voltage circuit is completely disconnected. However, the present invention sets a controller and a sensor 70. Even if the high-voltage electricity needs to be disconnected based on the information obtained by the sensor 70, the high-voltage electricity can still be turned on under extreme conditions to improve safety. For example, the contactor of the present invention is applied to the electric vehicle 10000. When the circuit information indicates that the contactor needs to be disconnected but the vehicle 10000 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 electrical connection between the second end 32 and the second terminal 2 is disconnected.

[0407] Furthermore, the controller is used to obtain the temperature, voltage or current of the first terminal 1 or the second terminal 2 or the joint electric bar 30 according to the circuit signal;

[0408] The controller is configured to disconnect the electrical connection between the second conductive section 302 and the second terminal 2 when the temperature of the first terminal 1 or the second terminal 2 or the junction electrode 30 is greater than a first temperature threshold; and / or the voltage is greater than a first voltage threshold; and / or the current is greater than a first current threshold.

[0409] The controller is also configured to close the electrical connection between the second conductive section 302 and the second terminal 2 when the temperature of the first terminal 1 or the second terminal 2 or the joint electrical bus 30 is less than a second temperature threshold; and / or the voltage is less than a second voltage threshold; and / or the current is less than a second current threshold, wherein the second temperature threshold is less than or equal to the first temperature threshold, the second voltage threshold is less than or equal to the first voltage threshold, and the second current threshold is less than or equal to the first current threshold.

[0410] That is to say, the contactor of the present invention, by providing a sensor and a controller, can disconnect the contactor when the voltage of the high-voltage circuit to which the contactor is connected exceeds a set first voltage threshold, the current exceeds a set first current threshold, or the temperature exceeds a set first temperature threshold, thereby improving the safety of the contactor, reducing the safety hazards of the high-voltage circuit, and avoiding burning of the contactor.

[0411] Furthermore, when the voltage of the high-voltage circuit to which the contactor is connected drops below the set second voltage threshold, the current drops below the set first current threshold, or the temperature drops below the set first temperature threshold, the contactor can be controlled to close again so that the high-voltage circuit to which the contactor is connected can be switched to the working state in time, which can effectively improve the safety of use and reduce property losses.

[0412] like Figure 56As shown, according to some embodiments of the present invention, the device further includes a housing 206, which defines an accommodation space. The junction bus 30, the first terminal 1, the second terminal 2, and the drive device 40 are all disposed within the accommodation space, with at least portions of the first terminal 1 and the second terminal 2 extending out of the housing 206. Thus, the housing 206 can isolate the drive device 40 from the outside world, improving operational stability while reducing interference from the outside environment on the fourth drive coil 401 and the third microswitch 402, thereby improving the control response efficiency of the low-voltage control portion.

[0413] Furthermore, a low-voltage signal terminal 60 is provided on the outside of the housing 206. The low-voltage signal terminal 60 is pluggably provided on the housing 206 and connected to the fourth drive coil 401. In some embodiments, the housing 206 is provided with a wiring harness outlet, through which the low-voltage signal terminal 60 is led to the outside of the housing. In other embodiments, the low-voltage signal terminal 60 is fixed to the housing 206 by plugging, and a corresponding plug interface is provided on the housing 206. The plug interface introduces a metal wire into the housing 206 to electrically connect to the fourth drive coil 401.
