[0065] The electronic device 1000 may be a battery pack, a motor controller, an on-board charger, or a component integrated with the above three.

The controller can control the on and off of the current of the relay core 3, thereby controlling the on and off of the current between the battery 61 and the power load, thereby achieving the purpose of controlling the power load.

[0066] One relay core 3, two relay cores 3, or three relay cores 3 may be provided between the battery 61 and the electrical load, and the present application does not impose any restrictions on this.

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.

[0091] 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.

[0092] 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 33. In this embodiment, no matter whether the coil 3821 is energized or de-energized, no matter whether the contact 33 is rising or falling, the second spring 310 is always in a compressed state, so that when the contact 33 contacts the first power terminal 31 and the second power terminal 32, the second spring 310 can give the contact 33 an upward thrust, thereby enabling the contact 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 33 and the first power terminal 31 and the second power terminal 32.

[0093] Please refer to Figure 4 The electronic device 1000 further includes a first copper bar 35 and a second copper bar 36, and the relay core 3 is connected to the control circuit of the electronic device 1000 through the first copper bar 35 and the second copper bar 36. Specifically, the first copper bar 35 has a first end and a second end that are arranged oppositely, the first end is connected to the first power terminal 31, and the second end is connected to one of the electronic devices 6 in the electronic device 1000. The second copper bar 36 has a third end and a fourth end that are arranged oppositely, the third end is connected to the second power terminal 32, and the fourth end is connected to another electronic device 6. The electronic device 1000 can control the contact 33 of the relay core 3 to be attracted with the first power terminal 31 and the second power terminal 32, so that the electronic devices 6 arranged at both ends of the relay core 3 are connected. Similarly, the electronic device 1000 can also control the contact 33 of the relay core 3 to be separated from the first power terminal 31 and the second power terminal 32, so that the electronic devices 6 arranged at both ends of the relay core 3 are disconnected from each other.

[0094] 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 accommodating cavity 11. To solve the above problem, in one embodiment of the utility model, the first end of the first copper busbar 35 is welded to the first power terminal 31, and the third end of the second copper busbar 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.

[0095] The electronic device 1000 also includes a potting glue 2, which is used to fix the relay core 3 in the accommodating cavity 11. The potting glue 2 is filled in the accommodating cavity 11. 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 accommodating cavity 11. Second, the potting glue 2 can provide support for the arrangement of the relay core 3 in the accommodating cavity 11, thereby improving the stability of the arrangement 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 box 1 through the potting glue 2, and quickly dissipate the heat outward through the box 1, thereby reducing the influence of heat accumulation on the electronic device 1000 and improving the working stability of the electronic device 1000.

[0096] In one embodiment of the utility model, the electronic device 1000 includes a plurality of relay cores 3, which are arranged in the same accommodating cavity 11 at intervals from each other, and a potting glue 2 is provided between two adjacent relay cores 3. The relay core 3 is fixedly connected to the housing 1 through the potting glue 2, so as to reduce the gap between adjacent relay cores 3, reduce the shaking amplitude of the relay core 3 when encountering vibration, and improve the seismic resistance of the relay core 3.

[0097] 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.

[0098] 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 box body 1, and the opening is sealed by the potting glue 2, so as to prevent external moisture or dust from entering the accommodating cavity 11 through the opening and affecting the normal use of the relay core 3.

[0099] The first power terminal 31 and the second power terminal 32 can be covered 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 box body 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 wiring copper bar 35 or the second power terminal 32 and the second wiring copper bar 36.

[0100] In another possible implementation of the present invention, 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 accommodating 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, 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.

[0101] 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.

[0102] Please refer to Figure 5 The electronic device 1000 further includes a circuit board 5, which is electrically connected to the coil 3821. The controller is integrated in the circuit board 5. The controller can control the on and off of the current of the coil 3821 through the circuit board 5, thereby controlling the on and off of the current 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, the relay core 3 is provided with a wiring harness interface, and the coil 3821 is electrically connected to the wiring harness interface. The electronic device 1000 also 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.

[0103] In another possible implementation 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 of the relay core 3, and the other end is connected to the circuit board 5. The signal pin and the circuit board can be connected by welding or bonding, and the present invention does not limit this. In this implementation, the relay core 3 and the circuit board 5 are connected by the signal pin 4, thereby eliminating the use of a wiring harness, saving the space required for arranging the wiring harness, reducing the space required for installing the relay core 3, and making the layout of the electronic device 1000 more compact.

[0104] There are many ways to connect the relay core 3 to the circuit board 5 through the signal pin 4. In one embodiment of the present invention, the electronic device 1000 includes multiple relay cores 3 and multiple groups of signal pins 4. One end of the signal pin 4 is connected to the relay core 3, and the other end is connected to the circuit board. Each relay core 3 and each group of signal pins 4 are arranged in a one-to-one correspondence. When a connection failure occurs in the relay core 3, maintenance personnel can quickly check the faulty part, thereby reducing the maintenance cost of the electronic device 1000 and improving the maintenance efficiency of the electronic device 1000.

[0105] In order to improve the connection efficiency between the relay core and the circuit board, in one embodiment of the present invention, each signal pin 4 is arranged along the same side of each relay core 3, so that the connection between the circuit board 5 and the relay core 3 is concentrated on the same side of the relay core 3, thereby optimizing the wiring process between the circuit board 5 and the relay core 3, improving the wiring efficiency between the circuit board 5 and the relay core 3, and reducing the wiring cost between the circuit board 5 and the relay core 3.

[0106] Please refer to Figure 6 In other possible implementation modes of the utility model, the signal pin 4 and the circuit board may also be connected in other ways. Specifically, in this implementation mode, each signal pin includes a first section (not shown in the figure) and a second section 41 which are connected to each other. The first section is connected to the relay core 3, and the second section 41 is connected to the circuit board 5. The second sections 41 of multiple signal pins 4 are arranged in parallel and at intervals. The second sections 41 of multiple signal pins 4 are all arranged close to the same relay core 3. In this way, the connection between the signal pin 4 and the circuit board 5 is concentrated at one place, thereby reducing the movement stroke of the connecting device, speeding up the wiring rhythm of the wiring device, and improving the wiring efficiency of the wiring device connecting the signal pin 4 and the circuit board 5.
