[0059] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

Taking the motor control system as an example, please refer to Figure 1 , Figure 1 A topological diagram of the integrated relay provided by the utility model applied in a motor control system. Figure 1The topological diagram of the integrated relay provided by the utility model in the motor control system is shown in FIG. 2. The electrical device 2000 includes a battery 2100, a motor controller 2200 and an integrated relay 1000. The battery 2100 is connected to the motor controller 2200, and the battery 2100 is used to store and release electrical energy to maintain the normal use of the motor controller 2200. The motor controller 2200 is used to connect to the motor 3000, and the motor controller 2200 can adjust the motion parameters of the motor 3000 to control the motion of the motor 3000, and drive the wheels to rotate through the motor 3000. The integrated relay 1000 is provided between the battery 2100 and the motor controller 2200. The integrated relay 1000 is used to control the on and off of the current between the battery 2100 and the motor controller 2200. Specifically, the integrated relay 1000 includes a first relay core K1 and a second relay core K2. The first end of the first relay core K1 is connected to the positive electrode of the battery 2100, and the second end of the first relay core K1 is connected to the motor controller 2200. When the first relay core K1 and the second relay core K2 are attracted, a closed loop is formed between the battery 2100 and the motor controller 2200, and the motor controller 2200 is powered on. When the first relay core K1 and the second relay core K2 are disconnected, the loop between the battery 2100 and the motor controller 2200 is disconnected, and the motor controller 2200 loses power.

[0062] The electrical device 2000 further includes a first resistor R1, and the integrated relay 1000 further includes a third relay core K3, wherein the first end of the third relay core K3 is connected to the positive electrode of the battery 2100 and the first end of the first relay, and the second end of the third relay core K3 is connected to the first resistor R1; the second end of the first resistor R1 is connected to the second end of the first relay core K1 and the electrical load. When the circuit current is too large, the controller can control the circuit of the first relay core K1 to be disconnected and the circuit of the third relay core K3 to be closed, so that the current is transmitted through the first resistor R1 instead of the first relay core K1, thereby increasing the circuit resistance and protecting the circuit safety.

[0063] The battery 2100 includes a first battery 2110 and a second battery 2120, the electrical device 2000 further includes a second resistor R2, and the integrated relay 1000 further includes a fourth relay core K4, the first end of the fourth relay core K4 is connected to the negative electrode of the first battery 2110 and the positive electrode of the second battery 2120, the second end of the fourth relay core K4 is connected to the first end of the second resistor R2, and the second end of the second resistor R2 is connected to the neutral line of the motor controller 2200. When the fourth relay core K4 is turned on, the current between the first battery 2110 and the second battery 2120 can be guided to the ground through the second resistor R2, and when the current passes through the second resistor R2, heat will be generated due to the obstruction of the second resistor R2, thereby increasing the temperature of the battery pack and improving the heat release performance of the battery pack in a low temperature environment.

[0064] The electrical device 2000 further includes a DC connector 2300. The integrated relay 1000 includes a fifth relay core K5 and a sixth relay core K6.

The first end of the sixth relay core K6 is connected to the positive electrode of the DC connector 2300, and the second end is connected to the positive electrode of the battery 2100. When the fifth relay core K5 and the sixth relay core K6 are attracted, a closed loop is formed between the DC connector 2300 and the battery 2100, and the current of the external power source can flow to the battery through the DC connector 2300, thereby realizing fast charging of the battery 2100.

[0065] The integrated relay 1000 further includes a seventh relay core K7, a first end of which is connected to the positive electrode of the DC connector 2300, and a second end of which is connected to the neutral line of the motor controller 2200. The seventh relay core K7 can form a closed loop with the fifth relay core K5. When the seventh relay core K7 and the fifth relay core K5 are turned on by the controller, the current of the DC connector 2300 can reach the neutral line of the motor controller 2200 through the seventh relay core K7, and after introducing an additional charging voltage at the neutral line, the current reaches the battery 2100, thereby achieving boost charging of the battery 2100 and improving the charging efficiency of the charging device.

[0066] The electrical equipment 2000 also includes a first capacitor C1, a first end of the first capacitor C1 is connected between the second end of the first relay core K1 and the first end of the motor controller 2200, and the first end of the first capacitor C1 is connected to the second end of the sixth relay core K6; the second end of the first capacitor C1 is connected to the second end of the fifth relay core K5, and the first capacitor C1 is used to smooth the circuit voltage, reduce the voltage fluctuation of the circuit, and absorb the harmonics of the circuit, thereby maintaining the stability of the circuit.

[0067] The electrical device 2000 further includes a second capacitor C2, a first end of the second capacitor C2 being connected to the positive electrode of the DC connector 2300, and a second end of the second capacitor C2 being connected to the second end of the motor controller 2200.

[0068] The electrical device 2000 may further include an OBC module and / or a DC module. The OBC module and the DC module are connected between the AC connector and the battery.

[0069] Please refer to Figure 2 The integrated relay 1000 includes: a housing 1 and a plurality of relay cores 3. The housing 1 is an integral part and has a mounting cavity 11. The plurality of relay cores 3 are spaced apart from each other and are packaged together in the mounting cavity 11. The technical solution of the utility model packages the relay cores 3 after the housing is eliminated in the mounting cavity 11 of the housing, thereby reducing the volume of a single relay core 3, thereby reducing the volume of the integrated relay 1000, and improving the aperture utilization rate of the integrated relay 1000 for electrical equipment.

[0070] Hereinafter, the integrated relay 1000 provided by the present invention will be described in detail with reference to the accompanying drawings.

[0071] The integrated relay 1000 includes a housing 1, which serves as a supporting frame of the integrated relay 1000 and is used to support and connect the various components of the integrated relay 1000. The housing 1 may be rectangular, square, or other regular or irregular shapes, which is not limited by the present invention. The housing 1 may be a part of a device rack or a structure independent of the device rack, which is not limited by the present invention.

[0072] The housing 1 has an opening and an installation cavity 11, the opening is connected to the installation cavity 11, the relay core 3 can be arranged in the installation cavity 11 through the opening, and multiple relay cores 3 are arranged in the installation cavity 11 at intervals. The relay core 3 is used to be connected to the control circuit of the electrical device. The relay core 3 can control the current direction of the electrical device by controlling its own on and off, thereby realizing different electrical functions. The relay cores 3 can be placed in the installation cavity 11 vertically, horizontally, or partially vertically and partially horizontally, and the utility model does not limit this.

[0073] The integrated relay 1000 also includes a potting glue 2, which is filled in the installation cavity 11 to fix the multiple relay cores 3. The potting glue 2 has two functions. First, the potting glue 2 can provide fixation for the installation of the relay core 3 in the installation cavity 11. Second, the potting glue 2 can provide support for the setting of the relay core 3 in the installation cavity 11, thereby improving the stability of the setting of the relay core 3. The material of the potting glue 2 can be epoxy resin, phenolic resin, natural fiber, or one or more thereof, and the utility model does not limit this. In one embodiment of the utility model, the potting glue 2 includes one or more of insulating resin, aluminum nitride, and boron nitride. The use of insulating resin, aluminum nitride, and boron nitride not only has good insulation, but also has good thermal conductivity. The relay core 3 can quickly conduct heat to the housing 1 through the potting glue 2, and quickly dissipate the heat outward through the housing 1, thereby reducing the influence of accumulated heat on the integrated relay 1000 and improving the stability of the integrated relay 1000.

[0074] In one embodiment of the utility model, a potting glue 2 is provided between two adjacent relay cores 3, and the potting glue 2 is filled between the relay cores 3, so as to reduce the gap between the relay cores 3, reduce the shaking amplitude of the relay core 3 when encountering vibration, and improve the anti-seismic ability of the relay core 3.

[0075] Please refer to Figure 3 The relay core 3 includes a first power terminal 31, a second power terminal 32 and a contact 33. The first power terminal 31 and the second power terminal 32 are used to be connected to the circuit of the electrical device. The relay core 3 can control the on-off of the circuit between the first power terminal 31 and the second power terminal 32 to control the on-off of the circuit of the electrical device at that location, thereby realizing circuit control of the electrical device.

[0076] The contact member 33 is movably disposed in the housing 1 and has a movement of approaching or moving away from the first power terminal 31 and the second power terminal 32, and is used to control the on and off of the current between the first power terminal 31 and the second power terminal 32. Specifically, the contact member 33 includes a main body 331 and a first contact portion 332 and a second contact portion 333 disposed at both ends of the main body 331. When the contact member 33 approaches the first power terminal 31 and the second power terminal 32, the first contact portion 332 of the contact member 33 contacts the first power terminal 31, and the second contact portion 333 contacts the second power terminal 32, so that the circuit between the first power terminal 31 and the second power terminal 32 is mutually conductive. When the connector is away from the first power terminal 31 and the second power terminal 32, the first contact portion 332 of the contact member 33 is separated from the first power terminal 31, and the second contact portion 333 is separated from the second power terminal 32, and the circuit between the first power terminal 31 and the second power terminal 32 is disconnected.

[0077] The relay core 3 also includes a fixing member 34, which is used to provide support for the arrangement of the first power terminal 31, the second power terminal 32 and the contact member 33. Specifically, the fixing member 34 has a cavity 341 with an opening at one end, and the surface of the fixing member 34 is provided with a first through hole and a second through hole connected to the cavity 341; the first power terminal 31 extends into the cavity 341 from the first through hole, and the second power terminal 32 extends into the cavity 341 from the second through hole. The contact member 33 is movably arranged in the cavity 341, and completes contact and separation with the first power terminal 31 and the second power terminal 32 in the cavity 341. The arrangement of the fixing member 34 can provide protection for the movement of the contact member 33. It can avoid other structures in the electrical equipment from affecting the movement of the contact member 33, and extend the service life of the relay core 3.

[0078] When the contact 33 is separated from the first power terminal 31 and the second power terminal 32, an arc is easily generated, and the arc may cause burns to the contact 33, the first power terminal 31 and the second power terminal 32. In order to reduce the impact of the arc on the contact 33, the first power terminal 31 and the second power terminal 32, in one embodiment of the utility model, the cavity 341 is filled with an arc extinguishing gas, which can be hydrogen, nitrogen or sulfur dioxide, and the utility model does not limit this. The arc extinguishing gas is used to extinguish the arc when an arc is generated by the contact 33, the first power terminal 31 and the second power terminal 32, to protect the safety of the contact 33, the first power terminal 31 and the second power terminal 32, and to extend the service life of the relay core 3.

[0079] The material of the fixing member 34 can be plastic or ceramic, and the present invention does not limit this. In one embodiment of the present invention, the fixing member 34 is made of ceramic, so that the fixing member 34 can provide stable support for the first power terminal 31 and the second power terminal 32, shorten the arc occurrence time, and protect the safety of the contact member 33, the first power terminal 31, and the second power terminal 32.

[0080] The relay core also includes an arc extinguishing hood 320, which is arranged on the periphery of the fixing member. When an arc is generated between the contact member 33 and the first power terminal 31 and the second power terminal 32, the arc extinguishing hood 320 can separate the arc from the contact point, and use the diffusion effect of the arc in the arc extinguishing hood 320 to quickly extinguish the arc. The arc extinguishing hood 320 will generate a large amount of heat during the arc extinguishing process. In order to reduce the accumulation of heat on the arc extinguishing hood 320 and the impact on the arc extinguishing hood 320. In one embodiment of the present application, the potting glue 2 is wrapped around the arc extinguishing hood 320 and is in direct contact with the arc extinguishing hood 320, so as to increase the contact area between the potting glue 2 and the arc extinguishing hood 320, improve the heat conduction effect of the potting glue 2 on the arc extinguishing hood 320, improve the heat dissipation effect of the arc extinguishing hood 320, reduce the impact of heat on the arc extinguishing hood 320, and improve the stability of the operation of the arc extinguishing hood 320.

[0081] The relay core 3 also includes a driving assembly 38 and a sealing cover 37. The sealing cover 37 covers the opening of the cavity 341, so that the contact 33 disposed in the cavity 341 is isolated from the outside air, thereby reducing the influence of moisture and impurities in the outside air on the contact between the contact 33 and the first terminal and the second terminal. The sealing cover 37 is also provided with a third through hole 371, and the third through hole 371 is used for the driving assembly 38 to pass through.

[0082] The driving assembly 38 is used to drive the contact member 33 to move. The driving assembly 38 can be a motor or a cylinder, and the utility model does not limit this. The driving assembly 38 includes a mounting frame 381, a stator 382 and a mover 383. The mounting frame 381 serves as a supporting frame of the driving assembly 38 and is used to support and connect various parts of the supporting assembly. The stator is arranged on the mounting frame 381, and the stator is used to generate a magnetic field, thereby driving the mover 383 to move upward. The mover 383 is at least partially sleeved in the stator 382, ​​and the mover 383 is used to drive the contact member 33 to move closer to or away from the first power terminal 31 and the second power terminal 32. Specifically, the stator 382 includes a stator core 3822 and a coil 3821. The stator core 3822 is used to provide support for the arrangement of the coil 3821, and the coil 3821 is wound on the stator core 3822. The coil 3821 is connected to an external power source and can convert the electrical energy of the external power source into magnetic energy, thereby attracting the mover 383 to move upward. The mover 383 is sleeved in the stator 382. The mover 383 includes a body 3831 and a connecting shaft 3832. The body 3831 is arranged on the side of the stator core 3822 away from the first power terminal 31 and the second power terminal 32. One end of the connecting shaft 3832 is connected to the body 3831, and the other end passes through the third through hole 371, the stator core 3822 and the third through hole 371 in sequence to connect with the contact member 33. In order not to destroy the sealing of the cavity 341, the connecting shaft 3832 and the third through hole 371 are sealed. The main body 3831 of the mover 383 is made of magnetic material. When the coil 3821 is energized, the coil 3821 generates a magnetic field at the stator core 3822, thereby attracting the main body 3831 to move upward. The main body 3831 moves upward, thereby driving the connecting shaft 3832 to move upward. The movement of the connecting shaft 3832 drives the contact 33 to move upward, and finally makes the contact 33 contact the first power terminal 31 and the second power terminal 32, and the circuit between the first power terminal 31 and the second power terminal 32 is conducted. When the coil 3821 loses power, the magnetic field generated by the coil 3821 disappears, the mover 383 falls downward under the action of gravity, the contact 33 separates from the first power terminal 31 and the second power terminal 32, and the circuit between the first power terminal 31 and the second power terminal 32 is disconnected.

[0083] In one embodiment of the present invention, the stator 382 is directly in contact with the potting compound 2, thereby increasing the contact area between the potting compound 2 and the stator 382, ​​improving the thermal conductivity of the potting compound 2 to the coil 3821, and further improving the heat dissipation capacity of the drive component 38, thereby improving the working stability of the drive component 38.

[0084] In one embodiment of the present invention, the driving assembly 38 further includes a first spring 39, which is sleeved outside the connecting shaft 3832, one end of the first spring 39 is connected to the stator core 3822, and the other end is connected to the body 3831 of the mover 383. When the coil 3821 is energized, the body 3831 moves upward and is compressed by the first spring 39. When the coil 3821 loses power, the first spring 39 is released and pushes the body 3831 to move downward, thereby accelerating the falling speed of the body 3831, and then after the coil 3821 is powered off, the connector can be quickly separated from the first power terminal 31 and the second power terminal 32, thereby improving the response speed of the relay core 3.

[0085] In one embodiment of the present invention, the driving assembly 38 further includes a second spring 310, which is sleeved on the outer periphery of the connecting shaft 3832, one end of the second spring 310 is connected to the stator core 3822, and the other end is connected to the contact member 33. In this embodiment, no matter whether the coil 3821 is energized or de-energized, no matter whether the contact member 33 is rising or falling, the second spring 310 is always in a compressed state, so that when the contact member 33 contacts the first power terminal 31 and the second power terminal 32, the second spring 310 can give the contact member 33 an upward thrust, thereby enabling the contact member 33 to be pressed against the first power terminal 31 and the second power terminal 32, thereby improving the stability of the connection between the contact member 33 and the first power terminal 31 and the second power terminal 32.

[0086] Please refer to Figure 4 and Figure 5 , the integrated relay 1000 further includes a circuit board 5, which is electrically connected to the coil 3821. A control program is integrated in the circuit board 5, and the circuit board 5 can control the on and off of the current of the coil 3821 through the setting of program control, thereby controlling the on and off of the current at both ends of the relay core 3. There are many ways to connect the circuit board 5 and the coil 3821. In one embodiment of the utility model, a wiring harness interface is provided outside the relay core 3, and the coil 3821 is electrically connected to the wiring harness interface. The integrated relay 1000 further includes a wiring harness, one end of which is connected to the circuit board 5, and the other end extends into the wiring terminal, so that the coil 3821 is electrically connected to the circuit board 5.

[0087] In some other possible implementations of the present invention, the relay core 3 further includes a signal pin 4, one end of the signal pin 4 is connected to the coil 3821, and the other end is used to connect to the circuit board 5. The signal pin 4 can be welded to the circuit board 5 or glued to the circuit board 5 by electric glue, and the present invention does not limit this. When the relay core 3 is connected to the circuit board 5, it can be as follows Figure 4 Each relay core 3 shown is equipped with a set of signal pins 4 to connect with a circuit board 5, which can also be as follows Figure 5The multiple relay cores 3 shown are equipped with a group of signal pins 4, which are connected to the circuit board 5. The utility model does not limit this. The signal pins 4 of the relay core 3 can be connected to the circuit board 5 in a direction perpendicular to the relay core 3, or in a direction parallel to the relay core 3. The utility model does not limit this. In this embodiment, the signal pins 4 are connected to the circuit board 5 instead of the wiring harness interface, which eliminates the use of the wiring harness and reduces the wiring cost of the coil 3821 and the circuit board 5.

[0088] Please refer to Figure 6 In order to connect the first power terminal 31 and the second power terminal 32 to the control circuit of the electrical equipment, the electrical equipment also includes a first wiring copper bus 35 and a second wiring copper bus 36. The first wiring copper bus 35 includes a first end and a second end that are relatively arranged, the first end is connected to the first power terminal 31, and the second end is connected to the control circuit. The second wiring copper bus 36 has a third end and a fourth end that are relatively arranged, the third end is connected to the second power terminal 32, and the fourth end is connected to the control circuit of the electrical equipment.

[0089] There are many ways to connect the first copper bar 35 to the first power terminal 31, the second copper bar 36, and the second power terminal 32. The first copper bar 35 and the first power terminal 31, the second copper bar 36, and the second power terminal 32 can be connected by screws or by bonding, and the utility model does not limit this. Considering that if the first copper bar 35 and the first power terminal 31, the second copper bar 36 and the second power terminal 32 are bonded, the stability of the connection between the first copper bar 35 and the first power terminal 31, the second copper bar 36 and the second power terminal 32 cannot be guaranteed. If the first copper bar 35 and the first power terminal 31, the second copper bar 36 and the second power terminal 32 are connected by screws, it is necessary to set a threaded hole with sufficient depth on the first power terminal 31 and the second power terminal 32 to ensure the stability of the connection between the first copper bar 35 and the first power terminal 31, the second copper bar 36 and the second power terminal 32. The provision of the threaded hole will undoubtedly increase the length of the first power terminal 31 and the second power terminal 32, thereby increasing the height of the relay core 3, and affecting the space utilization rate of the relay core 3 for the installation cavity 11. To solve the above problem, in one embodiment of the utility model, the first end of the first wiring copper bar 35 is welded to the first power terminal 31, and the third end of the second wiring copper bar 36 is welded to the second power terminal 32. Since they are no longer connected by threads, the first power terminal 31 and the second power terminal 32 do not need to reserve thread length, so as to reduce the length of the first power terminal 31 and the second power terminal 32, thereby reducing the length of the relay core 3 and improving the space utilization rate of the relay core 3 for electrical equipment.

[0090] In one embodiment of the utility model, the first power terminal 31 and the second power terminal 32 are arranged at the opening of the shell 1, and the opening is sealed by the potting glue 2, so as to prevent external moisture or dust from entering the installation cavity 11 through the opening and affecting the normal use of the relay core 3.

[0091] The first power terminal 31 and the second power terminal 32 can be either enclosed in the potting glue 2 or exposed outside the potting glue 2, and the present invention does not limit this. Specifically, in one embodiment of the present invention, the first power terminal 31 and the second power terminal 32 protrude from the opening outside the housing 1, so that the first power terminal 31 and the second power terminal 32 can be exposed outside the potting glue 2, thereby facilitating the connection between the first power terminal 31 and the first copper busbar 35 or the second power terminal 32 and the second copper busbar 36.

[0092] In another possible implementation of the utility model, the first power terminal 31 and the first copper busbar 35, and the second power terminal 32 and the second copper busbar 36 can be connected to each other first, and then potted in the installation cavity 11 by the potting glue 2. Specifically, in this implementation, the first end of the first copper busbar 35 is connected to the first power terminal 31, and the second copper busbar 36 is connected to the second power terminal 32 by welding, and the first end and the first power terminal 31, and the third end and the second power terminal 32 are all covered by the potting glue 2, so as to improve the stability of the connection between the first power terminal 31 and the first copper busbar 35, and the second power terminal 32 and the second copper busbar 36.

[0093] It can be understood that in other possible implementations of the present invention, the first end of the first wiring copper busbar 35 and the first power terminal 31 may be covered by the potting glue 2, and the second power terminal 32 and the second wiring copper busbar 36 may be exposed outside the potting glue 2, or the third end of the second wiring copper busbar 36 and the second power terminal 32 may be covered by the potting glue 2, and the first end of the first wiring copper busbar 35 and the first power terminal 31 may be exposed outside the potting glue 2. The present invention does not impose any restrictions on this.
