The two support plates 21 are arranged at intervals in the transverse direction. An assembly area 20 is formed between the two support plates 21, which assembly area 20 is used for mounting and moving the first magnetic core 3.

It should be noted that, in other embodiments, the extending direction of the supporting plate 21 may not be strictly perpendicular to the substrate 1, and the extending direction of the supporting plate 21 may form a small angle with the perpendicular line of the board surface of the substrate 1.

Referring to fig. 1 to 5, both support plates 21 are provided with a chute 22 extending obliquely, and the chute 22 extends obliquely upward in a long shape in a direction away from the base plate 1. The first magnetic core 3 is movably arranged between the two supporting plates 21, that is, the first magnetic core 3 is movably arranged in the assembly area 20, and two transverse ends of the first magnetic core 3 are respectively and rotatably connected in a chute 22, so that the first magnetic core 3 can move upwards or downwards along the extending direction of the chute 22, and meanwhile, the first magnetic core 3 can rotate relative to the chute 22, that is, the first magnetic core 3 can rotate relative to the supporting plates 21 and the supporting frame 2.

When the first magnetic core 3 moves obliquely downward in the extending direction of the chute 22, the first magnetic core 3 can gradually approach the side wall of the base plate 1.

Referring to fig. 1, in some embodiments, under the action of gravity of the first magnetic core 3, the first magnetic core 3 can automatically slide down the chute 22, so that the side surface of the first magnetic core 3 abuts against the side wall surface of the substrate 1, and the first magnetic core 3 can be relatively stably maintained in this state.

When the side surface of the first magnetic core 3 abuts against the side wall surface of the substrate 1, the side wall surface of the first magnetic core 3 facing the substrate 1 is one magnetic pole surface, the side wall surface of the first magnetic core 3 facing away from the substrate 1 is the other magnetic pole surface, and the polarities of the two magnetic pole surfaces are opposite.

Referring to fig. 1 to 5, in some embodiments, the assembly area 20 penetrates the support frame 2 in a direction perpendicular to the substrate 1. Therefore, the first magnetic core 3 can be mounted in the mounting region 20 from both side openings in the penetrating direction of the mounting region 20, and further, can be fitted into the slide groove 22 of the support plate 21.

In some embodiments, the side surface of the support frame 2 away from the base plate 1 is convexly provided with a connecting rib 23 which extends transversely, the connecting rib 23 is arranged between the two support plates 21, one end of the connecting rib 23 is connected with one support plate 21, and the other end of the connecting rib 23 is connected with the other support plate 21; the other support plate 21 is connected. Therefore, the connecting rib 23 can connect the two support plates 21, improving structural stability between the two support plates 21.

In some embodiments, the connection rib 23 is located at a bottom side edge of the fitting region 20, and the fitting region 20 is formed in an area between the connection rib 23 and the two support plates 21.

Referring to fig. 1 to 5, in some embodiments, a supporting block 11 is convexly disposed on a side wall of the substrate 1 facing the supporting frame 2, and a supporting groove 111 is concavely disposed on a top surface of the supporting block 11. Meanwhile, the end of the support frame 2 is provided with a hooking portion 24 engaged with the support groove 111, and the hooking portion 24 may be bent and extended downward from the lateral end of the support plate 21 and form a hook structure. The hooking portion 24 can be detachably hooked in the supporting groove 111, thereby detachably fixing the supporting frame 2 to the side wall of the base plate 1.

In other embodiments, the support frame 2 may be integrally formed on the side wall of the substrate 1 facing the first magnetic core 3, so that the two support plates 21 are integrally formed on the side wall of the substrate 1 facing the first magnetic core 3.

In some embodiments, the support blocks 11 are provided with at least two, at least two support blocks 11 being arranged on the side wall of the substrate 1 at a lateral interval, the at least two support blocks 11 being provided separately on opposite lateral sides of the support frame 2. At the same time, at least one hook portion 24 is respectively arranged at two transverse ends of the supporting frame 2, and the at least one hook portion 24 is correspondingly hung in the supporting groove 111 of the supporting block 11 one by one. By such design, both lateral ends of the supporting frame 2 can be hung to the corresponding supporting grooves 111 on the supporting blocks 11 through the hook parts 24, so that the supporting frame 2 can be stably fixed on the side wall surface of the substrate 1.

In some embodiments, the supporting blocks 11 are provided in a plurality, the plurality of supporting blocks 11 are divided into two groups, the two groups of supporting blocks 11 are arranged on the side wall of the substrate 1 at intervals in the transverse direction, and the two groups of supporting blocks 11 are respectively arranged on two opposite transverse sides of the supporting frame 2. Each group of the supporting blocks 11 comprises a plurality of supporting blocks 11 which are arranged at intervals in sequence. Correspondingly, a plurality of hook portions 24 are respectively arranged at two transverse ends of the supporting frame 2, and the plurality of hook portions 24 are correspondingly hung in the supporting grooves 111 of the supporting blocks 11 one by one. Therefore, the support frame 2 can be engaged with the support grooves 111 of the two sets of support blocks 11 through the two sets of hook portions 24 in a one-to-one correspondence manner, so that the support frame 2 can be more stably fixed on the side wall surface of the substrate 1.

Fig. 6 is a schematic structural view of the fixing frame 5 and the first magnetic core 3 in fig. 3. Fig. 7 is an exploded view of fig. 6. Fig. 8 is a side view of the mount 5 of fig. 7. Fig. 9 is a schematic structural view of the magnetic core assembly of fig. 1 in a mating installation. Fig. 10 is a state change diagram of fig. 9.

Referring to fig. 1 to 10, in some embodiments, the magnetic core assembly further includes a fixing frame 5, the fixing frame 5 is sleeved on the outer periphery of the first magnetic core 3, and the fixing frame 5 is rotatably connected in the sliding groove 22 of the supporting frame 2, that is, the first magnetic core 3 is rotatably connected to the sliding groove 22 of the supporting frame 2 through the fixing frame 5. Specifically, two opposite ends of the fixing frame 5 are respectively provided with a rotating part 50 in a protruding manner, and the two rotating parts 50 are coaxially arranged. The two rotating parts 50 are respectively rotatably connected in a chute 22, so that the fixing frame 5 and the first magnetic core 3 can be rotatably connected on the chute 22 of the supporting frame 2.

Referring to fig. 6 to 8, in some embodiments, the fixing frame 5 includes two end plates 51 and two clamping plates 52 integrally formed. The two end plates 51 are respectively provided at opposite ends of the first magnetic core 3 in the transverse direction, specifically, one end plate 51 is provided at one end of the first magnetic core 3 near one support plate 21, and the other end plate 51 is provided at one end of the first magnetic core 3 near the other support plate 21. Two clamping plates 52 are respectively disposed on two opposite sides of the first magnetic core 3, specifically, one clamping plate 52 is disposed on one side of the first magnetic core 3 close to the substrate 1, and the other clamping plate 52 is disposed on the other side of the first magnetic core 3 facing away from the substrate 1. Meanwhile, both ends of the clamping plates 52 are respectively connected to the one end plate 51, so that a clamping space is formed between the two end plates 51 and the two clamping plates 52, and the first magnetic core 3 is clamped and fixed in the clamping space between the two end plates 51 and the two clamping plates 52. The two rotating portions 50 are respectively protruded on the outer wall of the end plate 51 facing away from the other end plate 51, and the fixing frame 5 and the first magnetic core 3 are rotatably connected in the chute 22 by the rotating portions 50.

In some embodiments, the upper and lower ends of the end plate 51 are respectively provided with a convex clamping block 53, the clamping blocks 53 extend from the end of the end plate 51 towards the first magnetic core 3 in a convex manner, and the end of the first magnetic core 3 is clamped between the two clamping blocks 53 at the two ends of the end plate 51. Therefore, the first magnetic core 3 can be limited in the fixing frame 5 by the clamping block 53.

It should be noted that, in other embodiments, the fixing frame 5 and the first magnetic core 3 may be an integrally formed structure.

Referring to fig. 1 to 10, in some embodiments, a side wall of the substrate 1 facing the first magnetic core 3 is concavely provided with a clearance groove 13. The clearance groove 13 is in direct communication with the mounting area 20. The contour shape of the clearance groove 13 is consistent with the contour shape of the combination of the first magnetic core 3 and the fixing frame 5. Meanwhile, when the first magnetic core 3 abuts against the side wall surface of the base plate 1, the clamping plate 52 of the holder 5 on the side close to the base plate 1 can be extended into the escape groove 13 and abut against the groove surface of the escape groove 13. Therefore, the clamping plate 52 of the holder 5 on the side close to the substrate 1 can be accommodated in the clearance groove 13, and the first core 3 can be abutted against the side wall surface of the substrate 1.

In some embodiments, the depth of the clearance groove 13 corresponds to the thickness of the cleat 52. Therefore, when the clamping plate 52 on the side of the fixing frame 5 close to the base plate 1 abuts against the groove surface of the avoiding groove 13, the clamping plate 52 is just completely accommodated in the avoiding groove 13, and the magnetic pole surface of the first magnetic core 3 can just be located on the side wall surface of the base plate 1, as shown in fig. 9 and 10.

It should be noted that, in other embodiments, the thickness of the clamping plate 52 may be greater than or less than the depth of the clearance groove 13.

Referring to fig. 1, 9 and 10, the second magnetic core 4 is movably disposed on the other side of the base plate 1, and the second magnetic core 4 is used for being mounted on a movable member of a household appliance such as a refrigerator, for example, a door. When the box door is closed, the box door can drive the first magnetic core 3 to be close to the box body, and then the second magnetic core 4 is close to the substrate 1 and the first magnetic core 3. When the polarities of the first magnetic core 3 and the second magnetic core 4 are matched, the polarity of the magnetic pole face of the second magnetic core 4 facing the first magnetic core 3 is opposite to the polarity of the magnetic pole face of the first magnetic core 3 facing the second magnetic core 4, that is, the polarity of the magnetic pole face of the second magnetic core 4 facing the first magnetic core 3 is opposite. Therefore, the first magnetic core 3 and the second magnetic core 4 can be opposite to each other, and then the first magnetic core 3 and the second magnetic core 4 can be respectively abutted against two opposite sides of the base plate 1, so that the box door can be sucked and fixed at the front side opening of the box body.

When the first magnetic core 3 and the second magnetic core 4 are opposite to each other, if the magnetic pole face of the first magnetic core 3 facing the second magnetic core 4 is N pole, the magnetic pole face of the second magnetic core 4 facing the first magnetic core 3 is S pole; if the pole face of the first magnetic core 3 facing the second magnetic core 4 is an S pole, the pole face of the second magnetic core 4 facing the first magnetic core 3 is an N pole.

Fig. 11 is a schematic view of the magnetic core assembly of fig. 1 in a non-matching installation. Fig. 12 is a cross-sectional view of fig. 11. Fig. 13 is a state change diagram of fig. 11. Fig. 14 is a cross-sectional view of fig. 13.

As shown in fig. 11 to 14, when the polarities of the first magnetic core 3 and the second magnetic core 4 are not matched, the polarity of the magnetic pole face of the second magnetic core 4 facing the first magnetic core 3 is the same as the polarity of the magnetic pole face of the first magnetic core 3 facing the second magnetic core 4, that is, the polarity of the magnetic pole faces of the second magnetic core 4 and the first magnetic core 3 are the same. Therefore, the first magnetic core 3 and the second magnetic core 4 can repel each other, as shown in fig. 11.

When the first magnetic core 3 and the second magnetic core 4 repel each other, if the magnetic pole face of the first magnetic core 3 facing the second magnetic core 4 is N-pole, the magnetic pole face of the second magnetic core 4 facing the first magnetic core 3 is N-pole; if the pole face of the first magnetic core 3 facing the second magnetic core 4 is the S pole, the pole face of the second magnetic core 4 facing the first magnetic core 3 is also the S pole.

Referring to fig. 13 and 14, when the second magnetic core 4 gradually approaches the first magnetic core 3, the repulsive force of the second magnetic core 4 to the first magnetic core 3 gradually increases, and the repulsive force can drive the first magnetic core 3 and the fixing frame 5 to move obliquely upward along the sliding slot 22 against the gravity of the first magnetic core 3 and the fixing frame 5, i.e. the rotating portion 50 of the fixing frame 5 moves obliquely upward along the sliding slot 22. At the same time, the friction force F of the bottom side of the chute 22 against the first magnetic core 3, the friction force F of the rotating portion 50 of the pair of holders 5 is downward along the chute 22, and the repulsive force F of the second magnetic core 4 against the first magnetic core 3 is leftward as shown in fig. 13. Therefore, under the combined action of the friction force F and the repulsive force F, a rotation moment F1 is formed, so that the first magnetic core 3 is driven to rotate along the direction of the moment F1, and the first magnetic core 3 can roll upwards along the sliding groove 22. The rotational torque F1 can cause the first magnetic core 3 to spin about its rotation axis, i.e., the rotational torque can cause the first magnetic core 3 to turn over relative to the support frame 2.

As shown in fig. 15 to 20, as the second magnetic core 4 continues to approach the substrate 1, the rotation angle of the combination of the first magnetic core 3 and the fixing frame 5 gradually increases until the first magnetic core 3 is turned to a horizontal state, as shown in fig. 15 and 16, the distance between the rotation axis of the first magnetic core 3 and the substrate 1 is greater than or equal to the rotation radius of the first magnetic core 3, and the rotation radius of the first magnetic core 3 is the rotation radius of the fixing frame 5. At this time, the rotating portion 50 of the fixing frame 5 is located at the highest position. Thereafter, the combination of the first magnetic core 3 and the fixing frame 5 continues to be turned over relative to the supporting frame 2 and moves obliquely downward along the slide groove 22, as shown in the state of fig. 17 and 18. At this time, the other magnetic surface of the first magnetic core 3 gradually faces the second magnetic core 4, the polarities of the magnetic surfaces of the second magnetic core 4 and the first magnetic core 3 facing each other are opposite, the first magnetic core 3 of the second magnetic core 4 starts to attract each other, the attraction force of the second magnetic core 4 to the first magnetic core 3 can drive the first magnetic core 3 to move obliquely downwards along the sliding groove 22 until the other magnetic surface of the first magnetic core 3 is abutted against the side wall surface of the substrate 1, and the first magnetic core 3 and the second magnetic core 4 keep a stable state facing each other, as shown in fig. 19 and 20.
