[0002] In the prior art, an electromagnet is often used to drive movement in one direction. It usually consists of a static iron core and a moving iron core. After the electromagnet is energized, the moving iron core is magnetized to generate electromagnetic attraction, and the moving iron core is pulled toward the static iron core. There are also structures on the market that can achieve "generating two opposite driving movements", which are roughly the following two solutions: 1. By switching the power direction (switching polarity) to change the direction of the magnetic field generated by the electromagnet to achieve the purpose of reverse action, but due to the mechanism principle of the force, the force applied by this solution is relatively small compared to the unidirectional electromagnet under the same volume and power supply power, and the requirements for power supply facility configuration are higher; 2.

DETAILED DESCRIPTION

[0018] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0020] The directions and positions mentioned in the present invention, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only directions or positions with reference to the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but are not intended to limit the scope of protection of the present invention.

[0021] In the present invention, the "when the electromagnetic driving component does not form an electromagnetic field" refers to an initial state where no action occurs or a reset to an initial state.

[0022] The present invention provides an electromagnet capable of controlling single- and double-action motion, which comprises: an electromagnetic drive component for receiving a power of P A The first input power and power is P B The second input power supply, P A <P B , and after receiving the first input power supply and the second input power supply, electromagnetic fields of B1 and B2 are formed respectively, and the magnetic field strength of B2 is greater than the magnetic field strength of B1; the first moving part and the second moving part are respectively arranged on both sides of the electromagnetic drive assembly, and under the action of the electromagnetic field B1, only the first moving part is caused to move in the first direction X1, and under the action of the electromagnetic field B2, the first moving part is caused to move in the first direction X1 and under the action of the electromagnetic field B2, the second moving part is caused to move in the second direction X2. That is, two electromagnetic fields with different magnetic field strengths are realized by two input power supplies of different powers, and different electromagnetic fields have different electromagnetic forces on the same moving part. By setting different external forces that break the force balance of the first moving part and the second moving part, the minimum external forces for the first moving part and the second moving part to move are different. The electromagnetic force generated by the electromagnetic field B1 on the first moving part is not less than the minimum external force for the first moving part to move, and the electromagnetic force generated on the second moving part is less than the minimum external force for the second moving part to move, so the first moving part can be moved and the second moving part cannot be moved; the electromagnetic force generated by the electromagnetic field B2 on the first moving part is not less than the minimum external force for the first moving part to move, and the electromagnetic force generated on the second moving part is not less than the minimum external force for the second moving part to move, so the first moving part and the second moving part can be moved at the same time.

[0023] The first direction of the present invention can be the same direction or different directions. Specifically, it can be set by the positional relationship between the electromagnetic field formed by the electromagnetic driving assembly under the action of the first input power source and the second input power source and the first moving part and the second moving part.

[0024] In some embodiments of the present invention, a first assisting elastic member and a second assisting elastic member are included; when the electromagnetic drive component does not form an electromagnetic field, the first assisting elastic member and the second assisting elastic member respectively store energy to form elastic forces F1T and F2T; when the first moving component moves in the first direction, the first assisting elastic member releases energy to apply an assisting force to the first moving component in the first direction; when the second moving component moves in the second direction, the second assisting elastic member releases energy to apply an assisting force to the second moving component in the second direction.

[0025] In some embodiments of the present invention, a magnet is provided, so that when the electromagnetic driving component does not form an electromagnetic field, only under the action of the magnetic field of the magnet, a magnetic force F1Y opposite to the first direction X1 is formed between the first moving part, and a magnetic force F2Y is formed on the second moving part, and F1Y>F1T, F2Y>F2T is set, that is, in the initial state, the first assisting elastic member and the second assisting elastic member are respectively kept in an energy storage state by the magnetic force F1Y and the magnetic force F2Y; it is further set that, under the action of the electromagnetic field B1, a magnetic force F1A in the first direction X1 is formed on the first moving part, and a magnetic force F1A in the second direction X2 is formed on the second moving part. The magnetic force F2A, F1A+F1T>F1Y, F2A+F2T<F2Y, can break the force balance of the first moving component to make the first moving component move, and cannot break the force balance of the second moving component to make the second moving component unable to move; under the action of the electromagnetic field B2, a magnetic force F1B is formed on the first moving component in the first direction X1 and a magnetic force F2B is formed on the second moving component in the second direction X2, F1B+F1T>F1Y, F2B+F2T>F2Y, so the force balance between the first moving component and the second moving component can be broken, so that the first moving component and the second moving component can move at the same time.

[0026] In order to achieve the setting of different electromagnetic field sizes (i.e. different input power) for triggering the two tripping modes, the technical parameters can be adjusted to achieve this. Specifically, the spring elasticity parameters can be designed to achieve: F1T>F2T, and the materials (i.e. changing the magnetic energy product), cross-sectional area (i.e. changing the magnetic flux), air gap length, etc. of the first moving part 200 and the second moving part 300 can also be changed.

[0027] The following are some specific embodiments of the present invention.

[0028] Embodiment 1: A control electromagnet capable of single or double motion, the structure of which is as follows Figure 1 As shown, it includes a housing 140 and a first moving part 200 and a second moving part 300 respectively located on two sides of the housing 140 .

[0029] like Figure 2As shown, the housing 140 is a hollow structure with openings at both ends. It is made of magnetic conductive material, and an electromagnetic drive assembly 100 is arranged therein. Specifically, the electromagnetic drive assembly 100 includes a coil 110, a coil frame 120 and a static iron core 130. The coil 110, the coil frame 120, the static iron core 130 and the housing 140 are relatively fixed and non-displaced. The coil frame 120 has a main body 121 wound with the coil 110 and a first flange 122 and a second flange 123 arranged at both ends of the main body 121. The main body 121 is provided with a through hole opening to the first flange 122 and the second flange 123. The static iron core 130 is inserted and fixed in the through hole. The first flange 122 and the second flange 123 form a holding force on the coil 110 to keep the coil 110 outside the main body 121. The coil 110 is connected to the control circuit for energizing to form a magnetic field. The static iron core 130 can be fixed by common fixing structures such as tight fit, threaded fixing, adhesive fixing, pin fixing, limit fixing, etc.

[0030] The first movable component 200 includes a first armature 210 and a first magnet 220, wherein the first magnet 220 is fixed to a side of the first armature 210 close to the housing 140, and the first armature 210 and the first magnet 220 form a relatively fixed state without displacement; the second movable component 300 includes a second armature 310 and a second magnet 320, wherein the second magnet 320 is fixed to a side of the second armature 310 close to the housing 140, and the second armature 310 and the second magnet 320 form a relatively fixed state without displacement. A first assisting elastic member 230 is provided between the first movable component 200 and the electromagnetic drive assembly 100, and a second assisting elastic member 330 is provided between the second movable component 300 and the electromagnetic drive assembly 100. The magnetic poles of the first magnet 220 and the second magnet 320 are arranged in opposite directions, that is, Figure 1 , Figure 5 As shown, when the coil is powered, the magnetic poles at both ends of the static iron core are opposite, and form magnetic repulsion forces in opposite directions with the first magnet 220 and the second magnet 320 respectively. Figure 2 As shown, the first moving part 200, the housing 140, and the second moving part 300 are sequentially fitted, and the first assisting elastic member 230 and the second assisting elastic member 330 store energy to form elastic forces F1T and F2T respectively; under the action of the magnetic housing 140 and the magnetic static iron core 130, the first magnet 220 and the second magnet 320 realize a magnetic closed loop. At this time, the first magnet 220 and the static iron core 130 form a magnetic attraction force F1Y, F1Y>F1T; the second magnet 320 and the static iron core 130 form a magnetic attraction force F2Y, F2Y>F2T; at this time, the electromagnet assembly achieves a force balance, and the first moving part 200 and the second moving part 300 will be firmly attracted and fixed on the electromagnetic drive assembly 100.

[0031] This embodiment is further configured to make F1Y-F1T<F2Y-F2T, even if the electromagnetic driving force that causes the force balance of the first moving part 200 to fail is less than the electromagnetic driving force that causes the force balance of the second moving part 300 to fail, in this way, the magnetic field strength of the electromagnetic field can be controlled by controlling the input power of the coil 110, thereby achieving different effects of only the first moving part 200 moving or the first moving part 200 and the second moving part 300 moving at the same time. The control circuit connected to the coil 110 can transmit an input power of P to the coil 110. A The first driving electrical signal and input power are P B The coil 110 receives the first driving signal and the second driving signal, and forms electromagnetic fields B1 and B2 respectively. According to Ampere's loop law, the strength of the electromagnetic field is proportional to the input power. Set P A <P B Therefore, the magnetic field strength of B2 is greater than that of B1. Under the electromagnetic field of B1, magnetic repulsion F1A and magnetic repulsion F2A are respectively formed on the first moving part 200 and the second moving part 300, and it is set that F1A+F1T>F1Y, F2A+F2T<F2Y, as shown in FIG. Figure 3 As shown, under the electromagnetic field of B1, the force balance of the first moving part 200 fails and is pushed away from the electromagnetic drive assembly 100 under the action of the magnetic repulsion force, while the force balance of the second moving part 300 does not fail and is still attracted and fixed on the electromagnetic drive assembly 100. Under the electromagnetic field of B2, magnetic repulsion F1B and magnetic repulsion F2B are formed on the first moving part 200 and the second moving part 300 respectively, and it is assumed that F1B+F1T>F1Y, F2B+F2T>F2Y, as shown in FIG. Figure 4 As shown, under the electromagnetic field of B2, the force balance of the first moving part 200 and the second moving part 300 fails, so that under the action of the magnetic repulsion force, they are simultaneously pushed away from the electromagnetic driving assembly 100.

[0032] In this embodiment, the structures and materials of the first moving part 200 and the second moving part 300 are basically the same. The setting of different electromagnetic field sizes (i.e. different input power powers) for triggering the two tripping modes is achieved only by setting the spring elastic parameters, which is relatively easy to control.

[0033] The two ends of the static iron core 130 are opened near the first flange 122 and the second flange 123; the first armature 210 is provided with a mounting groove at the center of one side close to the static iron core 130, and the first magnet 220 is arranged in the mounting groove and forms an air gap with the end of the static iron core 130; the second armature 310 is provided with a mounting groove at the center of one side close to the static iron core 130, and the second magnet 320 is arranged in the mounting groove and forms an air gap with the end of the static iron core 130. A certain air gap length is ensured to avoid mechanical jamming.

[0034] Furthermore, both the first flange portion 122 and the second flange portion 123 are provided with a limiting protrusion, the first armature 210 and the second armature 310 are respectively provided with a limiting groove, and both ends of the first assisting elastic member 230 and the second assisting elastic member 330 are radially limited in the limiting protrusion and the limiting groove.

[0035] Embodiment 2: This embodiment provides an electromagnet that can control single and double action. Its specific structure is as follows: Figure 5 , Figure 6 As shown, it includes a housing 140 and a first moving part 200 and a second moving part 300 respectively located on both sides of the housing 140. The housing 140 is a hollow structure with closed ends, and an electromagnetic drive assembly 100 is arranged therein. Specifically, the electromagnetic drive assembly 100 includes a coil 110, a coil frame 120 and a static iron core 130. The coil 110, the coil frame 120, the static iron core 130 and the housing 140 are relatively fixed and non-displaced. The coil skeleton 120 has a main body 121 wound with the coil 110 and a first flange 122 and a second flange 123 arranged at both ends of the main body 121. The main body 121 is provided with a through hole opening to the first flange 122 and the second flange 123. The static iron core 130 is inserted and fixed in the through hole. The first flange 122 and the second flange 123 form a holding force on the coil 110 to keep the coil 110 outside the main body 121. The coil 110 is connected to the control circuit to form a magnetic field by energizing. An annular groove is provided at the center of the through hole, and the static iron core 130 is fixed in the annular groove.

[0036] In this embodiment, the static iron core 130 is a magnet, the first movable part 200 includes a first armature 210, and the second movable part 300 includes a second armature 310. The first armature 210 and the second movable part 300 are both located in the through hole and are respectively located on both sides of the static iron core 130 to form an air gap with the end of the static iron core 130. Under the action of the magnetic field of the static iron core 130, a magnetic attraction is formed on the first armature 210 and the second armature 310. The first armature 210 and the second armature 310 are respectively provided with a first drive rod 240 and a second drive rod 340 passing through the openings of the first flange portion 122 and the second flange portion 123. The first armature 210 and the second armature 310 are both located in the housing 140. The first drive rod 240 and the second drive rod 340 pass through the housing 140 and are fixedly connected to the first push plate 250 and the second push plate 350.

[0037] Furthermore, the two ends of the shell 140 along the direction of the central axis L protrude to form a hollow guide column 141, and the first drive rod 240 and the second drive rod 340 respectively pass through the guide column 141; the first push plate 250 is fixedly connected with the first guide ring 260, the first guide ring 260 is adapted to the guide column 141 and is sleeved outside the guide column 141 at one end, the second push plate 350 is fixedly connected with the second guide ring 360, the second guide ring 360 is adapted to the guide column 141 and is sleeved outside the guide column 141 at the other end, the first guide ring 260 and the second guide ring 360 are outer-mounted with a first assisting elastic member 230 and a second assisting elastic member 330, and the first assisting elastic member 230 and the second assisting elastic member 330 specifically use compression springs.

[0038] In the initial state where the electromagnetic drive assembly is not powered and no electromagnetic field is formed, under the action of the magnetic field of the static iron core 130, magnetic attraction forces F1Y and F2Y are respectively formed on the first armature 210 and the second armature 310, and the first booster elastic member 230 and the second booster elastic member 330 are compressed and stored to form elastic forces F1T and F2T, F1Y>F1T, F2Y>F2T, and the first moving part 200 and the second moving part 300 maintain a force balance. The control circuit connected to the coil 110 can transmit an input power of P to the coil 110. A The first driving electrical signal and input power are P B The coil 110 receives the first driving signal and the second driving signal, and forms electromagnetic fields B1 and B2 respectively. According to Ampere's loop law, the strength of the electromagnetic field is proportional to the input power. Set P A <P B, so the magnetic field strength of B2 is greater than that of B1. Under the electromagnetic field of B1, magnetic repulsion F1A and magnetic repulsion F2A are formed on the first moving part 200 and the second moving part 300 respectively, and it is set that F1A+F1T>F1Y, F2A+F2T<F2Y, that is, under the electromagnetic field of B1, the force balance of the first moving part 200 fails and is pushed away from the electromagnetic drive component 100 under the action of the magnetic repulsion, while the force balance of the second moving part 300 does not fail and it is still attracted and fixed on the electromagnetic drive component 100. Under the electromagnetic field of B2, magnetic repulsion F1B and magnetic repulsion F2B are respectively formed on the first movable component 200 and the second movable component 300, and it is set that F1B+F1T>F1Y, F2B+F2T>F2Y, that is, under the electromagnetic field of B2, the force balance of the first movable component 200 and the second movable component 300 fails, so that under the action of the magnetic repulsion, they are simultaneously pushed away from the electromagnetic drive component 100.

[0039] In this embodiment, the structures and materials of the first moving part 200 and the second moving part 300 are basically the same. The setting of different electromagnetic field sizes (i.e. different input power powers) for triggering the two tripping modes is achieved only by setting the spring elastic parameters, which is relatively easy to control.
