[0002] A relay is an electrical control device. When the change of the input quantity (excitation quantity) reaches the specified requirement, it causes the controlled quantity to undergo a predetermined step change in the electrical output circuit. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit.

[0028] As described above, the intelligently controlled combined relay of the present invention has the following beneficial effects:

[0029] 1. The present invention leads out a plurality of single-channel conductive strips from the side of a power distribution metal plate, and arranges a plurality of output metal plates to match the single-channel conductive strips. At the same time, a plurality of electromagnets are used to control the plurality of output metal plates respectively, and the electromagnets are connected to the distributor.

It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0049] like Figure 1-Figure 10 As shown, the present invention provides an intelligently controlled combined relay, comprising: a protection mechanism 1, a circuit access mechanism 2, a relay mechanism 3, a circuit output mechanism 4, a circuit control mechanism 5 and a lower-level control device 6;

[0050] The circuit access mechanism 2, the relay mechanism 3, the circuit connection mechanism 4, the circuit control mechanism 5 and the lower control device 6 are all installed inside the protection mechanism 1, and are protected by the protection mechanism 1. The circuit access mechanism 2 and the circuit connection mechanism 4 are both led out from the inside of the protection mechanism 1, and are used to connect circuits respectively, wherein the circuit access mechanism 2 is connected to the main circuit, and the circuit connection mechanism 4 is connected to the downstream electrical equipment.

[0051] The relay mechanism 3 is installed on the circuit access mechanism 2 in a detachable manner, so that the relay mechanism 3 can be replaced with different models as needed. And the relay mechanism 3 can be easily maintained. The circuit access mechanism 4 is installed at the inner bottom of the protection mechanism 1, and the circuit access mechanism 4 is located directly below the relay mechanism 3. The circuit control mechanism 5 is installed at the inner top of the protection mechanism 1, and the circuit control mechanism 5 is located directly above the relay mechanism 3. When the circuit control mechanism 5 is energized, magnetism will be generated, and the relay mechanism 3 will be provided with thrust through the force of repulsion of like charges, so that the relay mechanism 3 and the circuit access mechanism 4 are in contact to achieve circuit connection. When the circuit control mechanism 5 loses power, the magnetism disappears, and the relay mechanism 3 quickly rebounds through the memory and elastic rebound of the metal and the adsorption of the relay mechanism 3 to the circuit control mechanism 5, thereby cutting off the circuit. The traditional one is generally a magnetic switch, which adsorbs the metal sheet to achieve connection after power is turned on. When the power is turned off, the magnetism does not disappear immediately, so the metal sheet rebounds with a delay and the sensitivity is not high.

[0052] The lower control device 6 is connected to an external power supply. After being powered on, the lower control device 6 controls the circuit control mechanism 5, so that the circuit control mechanism 5 works according to the predetermined logic in the lower control device 6 and generates magnetic thrust as planned.

[0053] The protection mechanism 1 comprises an insulating bottom shell 101 and an insulating upper shell 102 , which are buckled with each other to form a cavity for protecting electrical components.

[0054] The relay mechanism 3 includes a power distribution metal plate 301, and a plurality of single-channel conductive strips 302 extend from the side of the power distribution metal plate 301. The number of single-channel conductive strips 302 provided can control the number of downstream circuits. Specifically, the current is first concentrated on the power distribution metal plate 301, and then diverted at the single-channel conductive strips 302. When the single-channel conductive strips 302 are connected to the downstream circuit, the downstream circuit is powered. There are gaps between adjacent single-channel conductive strips 302, so that when the circuit control mechanism 5 controls the single-channel conductive strips 302, the impact on the surrounding single-channel conductive strips 302 is reduced. A permanent magnet 303 is provided above the end of the single-channel conductive strip 302. The magnetic pole of the permanent magnet 303 facing the end of the circuit control mechanism 5 is the same as the magnetic pole of the circuit control mechanism 5 facing the end of the permanent magnet 303, so that after the circuit control mechanism 5 is energized to generate magnetism, the single-channel conductive strip 302 can be pushed to bend downward under the effect of like-pole repulsion. A contact point 304 is provided below the end of the single-channel conductive strip 302 for contacting the circuit access mechanism 4 after the single-channel conductive strip 302 is bent, thereby improving the contact stability.

[0055] The circuit access mechanism 4 includes an insulating connecting plate 401, which is installed on the inner bottom of the insulating bottom shell 101. The insulating connecting plate 401 is insulated to improve the safety of the equipment. The insulating connecting plate 401 is provided with an output metal plate 402 that is adapted to the number and position of the single-channel conductive strip 302. The output metal plate 402 is led out from the inside of the protection mechanism 1 and connected to the downstream circuit or electrical equipment. A connecting contact 403 is provided on the top of the output metal plate 402. The connecting contact 403 is located directly below the contact contact 304. When the single-channel conductive strip 302 is bent downward by force, the connecting contact 403 and the contact contact 304 will come into contact, thereby connecting the entire circuit.

[0056] The circuit control mechanism 5 is clamped on the inner top of the insulating upper shell 102, so that the circuit control mechanism 5 can be disassembled and conveniently installed on the insulating upper shell 102. The number of circuit control mechanisms 5 is adapted to the number and position of the single-channel conductive strips 302, and the circuit control mechanism 5 can control a plurality of single-channel conductive strips 302 one by one. And there are gaps between all the circuit control mechanisms 5 to reduce the magnetic field interference between the circuit control mechanisms 5. In order to improve the effect, a magnetic isolation layer can be wrapped on the outer surface of the circuit control mechanism 5 so that the magnetic direction of the circuit control mechanism 5 is concentrated downward to act on the permanent magnet 303.

[0057] In some embodiments, a gap is left between the top of the permanent magnet 303 of the present invention and the bottom of the circuit control mechanism 5, and a gap is left between the bottom of the contact point 304 and the top of the connecting contact 403. Thus, when the contact point 304 and the connecting contact 403 are in contact and energized, the interference of the current on the electromagnet 501 is reduced, and each component is independently arranged, which can facilitate subsequent expansion, modification and maintenance.

[0058] In some embodiments, the output metal plate 402 of the present invention is inserted from the top of the insulating connecting plate 401 and led out from the side of the insulating connecting plate 401, so that the main body of the output metal plate 402 is supported and wrapped by the insulating connecting plate 401 to improve the strength of the output metal plate 402, and after the output metal plate 402 is supported by the insulating connecting plate 401, the contact stability of the contact contact 304 and the connecting contact 403 can be improved. The output metal plate 402 is suspended from the inner bottom of the insulating bottom shell 101 to improve safety, and the output metal plate 402 will heat up after being energized. The suspended setting can prevent the output metal plate 402 from damaging the inner wall of the insulating bottom shell 101. The output metal plate 402 is led out from the side of the insulating bottom shell 101 to connect to downstream circuits or electrical equipment.

[0059] In some embodiments, the circuit access mechanism 2 of the present invention includes a ceramic pot 201, and the axis of the ceramic pot 201 is fixedly connected to a metal rod 202. The ceramic pot 201 is provided to support and protect the metal rod 202. The lower part of the metal rod 202 is provided with an access metal sheet 203, and the access metal sheet 203 extends to the outside of the insulating bottom shell 101 and is connected to the power supply.

[0060] A connecting metal plate 204 is provided on the upper part of the metal rod 202, and the connecting metal plate 204 is overlapped with the distribution metal plate 301. The current is transmitted through the route formed by the access metal sheet 203 and the metal rod 202, and finally transmitted to the relay mechanism 3 through the connecting metal plate 204, wherein the top of the ceramic pot 201 is used to increase the contact area with the connecting metal plate 204, thereby improving the connection stability of the connecting metal plate 204.

[0061] In some embodiments, the connecting metal plate 204 of the present invention is sleeved on the metal rod 202, and a threaded hole is provided at the top of the metal rod 202. The internal thread of the threaded hole is connected to a connecting fixture 205, and the connecting fixture 205 is used to fix the connecting metal plate 204. The connecting metal plate 204 is installed in a detachable manner, so that the connecting metal plates 204 of different widths and the connecting metal plates 204 of different materials can be replaced according to different needs.

[0062] The power distribution metal plate 301 is provided with a threaded hole, and the internal thread of the threaded hole is connected with a fixing bolt 305, and the fixing bolt 305 fixes the end of the connecting metal plate 204 on the metal rod 202, thereby realizing the convenient installation of the power distribution metal plate 301 and realizing a modular installation method, which can be freely assembled according to the use requirements, and the damaged parts can be replaced separately. Compared with the traditional welding method, it is more convenient and has a lower use cost.

[0063] In some embodiments, the circuit control mechanism 5 of the present invention includes an electromagnet 501 and a terminal 502, wherein the terminal 502 is arranged at the top of the electromagnet 501; the terminal 502 extends from the top of the insulating upper shell 102 to the outside of the insulating upper shell 102, wherein the electromagnet 501 is an iron core as a whole, and an electromagnetic coil is wound around the outer surface of the iron core, and the electromagnetic coil is connected to the terminal 502. When the terminal 502 is connected to the power supply, power is supplied to the electromagnetic coil to generate magnetism, and the permanent magnet 303 is pushed by the principle of like charges repelling each other. When the electromagnet 501 is demagnetized, the permanent magnet 303 is attracted to the iron core, and the connection between the connecting contact 403 and the contact contact 304 is quickly cut off under the elastic action of the single-channel conductive strip 302, thereby improving the control sensitivity.

[0064] In some embodiments, an expansion cavity 103 is provided on the insulating upper shell 102 of the present invention. The expansion cavity 103 is provided to increase the space inside the insulating upper shell 102. The lower control device 6 is installed inside the expansion cavity 103, so that there is enough safety space between the bottom of the lower control device 6 and the top of the ceramic pot 201, reducing the influence of the metal rod 202 on the lower control device 6 after being energized.

[0065] In some embodiments, the lower control device 6 of the present invention includes a distributor 601, half of the distributor 601 is located inside the extension cavity 103, and the other half of the distributor 601 is located outside the extension cavity 103;

[0066] A multi-channel interface 602 is installed on the top of the distributor 601. The multi-channel interface 602 is used to connect to an external host computer. The distributor 601 is logically programmed by the host computer to achieve the diversification of the control mode of the electromagnet 501 to adapt to the complex working environment. A plurality of control lines 603 are arranged on the side of the distributor 601. The control lines 603 correspond to the wiring terminals 502 one by one. When the distributor 601 issues a working instruction, the instruction controls whether the control line 603 is powered or not, so that the electromagnet 501 can generate magnetism and demagnetize according to the setting. The control line 603 does not need to be exposed to the outside as shown in the attached figure of the specification. The reason why the control line 603 in the attached figure of the specification is exposed to the outside is to facilitate the cutting of a single line during subsequent maintenance.

[0067] In some embodiments, the multi-channel interface 602 of the present invention is a 32-pin interface, which has better data transmission capability than the 485 interface, and can also supply power to the distributor 601. The distributor 601 is internally provided with a PCB control board to connect the multi-channel interface 602 and the control line 603, and the control line 603 is individually controlled to realize the conversion of the working logic.

[0068] In some embodiments, the single-channel conductive strip 302 of the present invention includes a flexible metal plate 3021, a through hole is provided in the middle of the flexible metal plate 3021, and a plurality of bimetal springs 3022 are connected inside the through hole. When the downstream circuit is short-circuited or at high temperature, the bimetal spring 3022 will deform due to the characteristics of the bimetal, pulling the flexible metal plate 3021 to rebound and cut off the circuit, protecting the main circuit and electrical equipment. The specific principle is similar to that of a thermal sensitive switch. Compared with using a fuse for protection, this structure has better resilience and does not require frequent replacement of the fuse.

[0069] The specific use process of the present invention is as follows:

[0070] Use the access metal sheet 203 to connect with the main circuit, and use the output metal plate 402 to connect with the downstream circuit or electrical equipment;

[0071] Use the multi-channel interface 602 to connect to the host computer, and perform signal interaction and control power input with the host computer;

[0072] The control mode of the distributor 601 to the electromagnet 501 is set by the host computer, and can be changed at any time according to the use needs;

[0073] When the circuit needs to be powered, the electromagnet 501 at the corresponding position is controlled to be powered on to work. After being powered on, the electromagnet 501 generates magnetism that repels the permanent magnet 303 of the same polarity, so that the contact point 304 and the connecting contact point 403 overlap to form a path.

[0074] In summary, the intelligently controlled combined relay of the present invention leads out a plurality of single-channel conductive strips 302 from the side of the distribution metal plate 301, and sets a plurality of output metal plates 402 to match the single-channel conductive strips 302. At the same time, the plurality of output metal plates 402 are respectively controlled by a plurality of electromagnets 501, and the electromagnets 501 are connected to the distributor 601. Thus, when in use, the on and off of a plurality of circuits can be respectively controlled, thereby improving the control capability of the relay.

[0075] A plurality of electromagnets 501 are controlled by the distributor 601, so that the on-off between the single-channel conductive strip 302 and the output metal plate 402 is individually controlled when in use. At the same time, combined control can be performed as needed to control the on-off between one or any several single-channel conductive strips 302 and the output metal plate 402, thereby achieving the effect of diversified control modes.

[0076] By connecting the metal rod 202 and the connecting metal plate 204 in a detachable manner, and connecting the distribution metal plate 301 and the connecting metal plate 204 in a detachable manner, and fixing the insulating connecting plate 401 to the inner bottom of the insulating bottom shell 101 by bolts, and installing the electromagnet 501 on the insulating upper shell 102 in a snap-fit ​​manner, it can be freely combined and expanded according to usage requirements.

[0077] The present invention leaves gaps between the permanent magnet 303 and the contact point 304 and the bottom of the electromagnet 501 and the top of the connecting contact 403 respectively, and generates magnetism through the electromagnet 501, and pushes the contact point 304 and the connecting contact 403 to overlap and energize through the principle of like charges repelling each other. When the electromagnet 501 loses its magnetic attraction, the single-path conductive strip 302 immediately rebounds to cut off the circuit. Compared with the demagnetization method of magnetic attraction, the rebound is faster and more sensitive.

[0078] By setting a through hole in the middle of the flexible metal plate 3021 and setting a bimetallic spring 3022 in the through hole, when the downstream circuit is short-circuited or the temperature is high, the bimetallic spring 3022 will deform due to the characteristics of the bimetal and pull the flexible metal plate 3021 to rebound and cut off the circuit, thereby protecting the main circuit and electrical equipment and achieving the effect of improving safety.

[0079] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0080] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
