In addition, the present invention also relates to an electronic device comprising the electromagnetic waveguide connection structure. Background Art

[0002] In radio equipment, electromagnetic radiation transmission devices such as antennas are used to transmit or send electromagnetic waves and are widely used in communications, radar, television, navigation, remote sensing, radio astronomy, electronic countermeasures and other fields.

[0003] In the related art, the connection between two separate electromagnetic devices is essentially that each electromagnetic device corresponds to a waveguide structure, and the waveguide structures corresponding to the two electromagnetic devices are connected by thread or screw fixing.

[0004] Taking the signal transmission between the outer casing and the chassis as an example, an antenna is provided on the outer casing, and the outer casing is mounted on the chassis. The electromagnetic transmission waveguide structure of the antenna must be connected to the electromagnetic transmission waveguide structure of the electromagnetic device in the chassis. In actual operation, it is necessary to first thread the corresponding electromagnetic transmission waveguide structures of the two, and then install the outer casing as a whole on the chassis, which makes the connection more complicated; when the outer casing and the chassis are disconnected, if the outer casing is directly removed, it is easy to cause damage to the waveguide transmission line, so it is necessary to open the outer casing and disconnect the waveguide transmission lines at the same time, which makes the disassembly more complicated.

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] The core of the present invention is to provide an electromagnetic waveguide connection structure, which can realize the transmission and interruption of signals between the first electromagnetic device and the second electromagnetic device, facilitate the connection and disassembly between the first electromagnetic device and the second electromagnetic device, and the operation is simple and fast. Another core of the present invention is to provide an electronic device including the above-mentioned electromagnetic waveguide connection structure.

[0055] The electromagnetic waveguide connection structure provided by the present invention includes a waveguide transmission part, an input waveguide structure 1 and an output waveguide structure 2, which are used to realize signal transmission between a first electromagnetic device and a second electromagnetic device, specifically to realize guided transmission of electromagnetic waves. Figure 1 , Figure 7 .

[0056] The waveguide transmission part has an open transmission space to guide electromagnetic waves. The open transmission space here refers to a non-enclosed space, such as two metal plate structures arranged opposite to each other. The metal plates can be flat or L-shaped or T-shaped structures to form an open transmission space. The open transmission space has an input end and an output end.

[0057] The input waveguide structure 1 is arranged on the upper side of the open transmission space, one end of the input waveguide structure 1 is used to connect the first electromagnetic device, and the other end of the input waveguide structure 1 is plugged into the input end of the open transmission space to input the electromagnetic wave signal into the open transmission space;

[0058] The output waveguide structure 2 is arranged at the lower side of the open transmission space, and one end of the output waveguide structure 2 is plugged into the output end of the open transmission space. The electromagnetic wave signal is transmitted to the output waveguide structure 2 through the guiding effect of the open transmission space, and further the other end of the output waveguide structure 2 is connected to the second electromagnetic device to realize the transmission of the signal to the second electromagnetic device.

[0059] Thus, by plugging the input waveguide structure 1 and the output waveguide structure 2 into the open transmission space, signal transmission between the first electromagnetic device and the second electromagnetic device is achieved; and by unplugging the input waveguide structure 1 and the output waveguide structure 2 from the open transmission space, the signal between the first electromagnetic device and the second electromagnetic device is cut off.

[0060] In the above process, the convenience of connection or disassembly operation is improved by plugging, which is convenient for connecting and disconnecting signals between two electromagnetic devices. The input and output ends of the specific open transmission space are structural forms for matching plugging, which are determined according to the specific structures of the input waveguide structure 1 and the output waveguide structure 2, such as slots, which can be round, square or other shapes. The size and shape of the slots at the input and output ends of the open transmission space can be set to be the same or different.

[0061] The above-mentioned electromagnetic waveguide connection structure is used to realize signal transmission between two electromagnetic devices, and specifically includes a waveguide transmission part, an input waveguide structure 1, and an output waveguide structure 2; an open transmission space for guiding electromagnetic wave transmission is provided on the waveguide transmission part, and the input waveguide structure 1 transmits the electromagnetic wave to the output waveguide structure 2 through the open transmission space; the input waveguide structure 1 is connected to the first electromagnetic device and then plugged into the input end of the open transmission space, so that the electromagnetic wave is input into the open transmission space, and then output through the output waveguide structure 2 plugged into the output end of the open transmission space to reach the second electromagnetic device connected to the output waveguide structure 2, thereby completing the transmission of the electromagnetic wave signal between the first electromagnetic device and the second electromagnetic device; by plugging or disconnecting the input waveguide structure 1, the output waveguide structure 2 and the open transmission space, the transmission and interruption of the signal between the first electromagnetic device and the second electromagnetic device can be realized, which facilitates the connection and disassembly between the first electromagnetic device and the second electromagnetic device, and the operation is simple and quick.

[0062] On the basis of the above embodiment, the waveguide transmission part includes a first metal plate 3 and a second metal plate 4 which are arranged opposite to each other, and an open transmission space is formed between the first metal plate 3 and the second metal plate 4;

[0063] The first metal plate 3 is provided with a first signal path 5 connected to the input waveguide structure 1, and the second metal plate 4 is provided with a second signal path 6 connected to the output waveguide structure 2;

[0064] The projections of the first signal path 5 and the second signal path 6 on the first metal plate 3 or the second metal plate 4 overlap.

[0065] Please refer to Figure 1 , Figure 2 , Figure 3 The waveguide transmission part includes a first metal plate 3 and a second metal plate 4 which are arranged relatively to each other, wherein the first metal plate 3 and the second metal plate 4 form an open transmission space, that is, a certain gap open structure is maintained between the connection areas of the input waveguide structure 1 and the output waveguide structure 2 to guide the conduction of electromagnetic waves, and the electromagnetic waves are guided and transmitted in the open transmission space.

[0066] Please refer to Figure 4 , Figure 5 A first signal path 5 connected to the input waveguide structure 1 is provided on the first metal plate 3, and a second signal path 6 connected to the output waveguide structure 2 is provided on the second metal plate 4, and the connections here are all plug-in connections.

[0067] The first signal path 5 and the second signal path 6 have an overlapping area in the length direction to form a transmission mode of electromagnetic waves transmitted by the input waveguide structure 1: the electromagnetic waves input into the open transmission space are transmitted to the second signal path 6 through the first signal path 5, and then transmitted to the output waveguide structure 2 through the second signal path 6.

[0068] One end of the first signal path 5 is used for plugging into the input waveguide structure 1, and the other end has a certain distance from the output waveguide structure 2 to form another transmission mode of the electromagnetic wave transmitted by the input waveguide structure 1: the electromagnetic wave input into the open transmission space is transmitted to the output waveguide structure 2 through the first signal path 5.

[0069] The two transmission modes of electromagnetic waves correspond to two transmission directions. The electromagnetic waves guided by these two transmission directions can be transmitted in pairs, so that the loss of electromagnetic waves in the transmission process can be reduced as much as possible, thereby improving the transmission efficiency of electromagnetic waves.

[0070] In addition, the first signal path 5 is arranged to protrude from the lower side of the first metal plate 3, and the second signal path 6 is arranged to protrude from the upper side of the second metal plate 4; the upper side of the first metal plate 3 and the lower side of the second metal plate 4 are both grounded or have an insulating layer, so that the electromagnetic waves are confined between the open transmission spaces, preventing the electromagnetic waves from radiating outward, and avoiding the influence of the outside world on the electromagnetic wave transmission.

[0071] In this embodiment, the input waveguide structure 1 and the first metal plate 3 can be set as independent components or as an integrated component, and the output waveguide structure 2 and the second metal plate 4 can be set as independent components or as an integrated component. The specific use can be combined with the actual application scenario.

[0072] On the basis of any of the above embodiments, the first signal path 5 and the second signal path 6 are arranged in parallel, and the lowest point of the first signal path 5 is higher than the highest point of the second signal path 6 .

[0073] Please refer to Figure 1 , Figure 2 The first signal path 5 and the second signal path 6 are arranged in parallel and overlap in the length direction, and at least partially overlap in the width direction. The first signal path 5 and the second signal path 6 form a parallel line transmission waveguide form, so that the electromagnetic waves transmitted by the input waveguide structure 1 can be transmitted to the output waveguide structure 2 through the first signal path 5 and the second signal path 6.

[0074] The first signal path 5 and the second signal path 6 also have at least partial overlap in the width direction. In one embodiment, when the first signal path 5 and the second signal path 6 completely overlap in the width direction, the center lines of the two in the length direction are in the same vertical plane.

[0075] In another embodiment, when the first signal path 5 and the second signal path 6 only partially overlap in the width direction, that is, the center lines of the two in the length direction are not located in the same vertical plane.

[0076] Both of the above two embodiments can realize effective signal transmission of the electromagnetic waves transmitted by the input waveguide structure 1 to the output waveguide structure 2 through the first signal path 5 and the second signal path 6, so they can be selected according to different usage requirements.

[0077] The lowest point of the first signal path 5 is higher than the highest point of the second signal path 6, that is, the two signal paths are only misaligned in the length direction and will not contact each other in the height direction, thereby ensuring the reliability of the parallel line transmission waveguide structure in transmitting electromagnetic wave signals.

[0078] Based on any of the above embodiments, the center line of the first signal path 5 and the center line of the second signal path 6 are in the same vertical plane and are perpendicular to the axis of the input waveguide structure 1 or the output waveguide structure 2 .

[0079] Please refer to Figure 1 , Figure 7 , the center line of the first signal path 5 and the center line of the second signal path 6 are in the same vertical plane, and the widths of the two signal paths can be consistent.

[0080] by Figure 1 For example, the center lines of the two signal paths are horizontal, and the corresponding axes of the input waveguide structure 1 or the output waveguide structure 2 are vertical, which limits the transmission direction of the electromagnetic waves.

[0081] By limiting the center line of the signal path and the axial direction of the output / input waveguide structure, it is suitable for signal transmission between more common electromagnetic devices and facilitates the processing of the first metal plate 3 and the second metal plate 4.

[0082] Based on any of the above embodiments, the width of the first signal path 5 is greater than or equal to the width of the second signal path 6 .

[0083] like Figure 5 and Figure 6 As shown, the first signal path 5 and the second signal path 6 are both regarded as rectangular structures. The first signal path 5 and the second signal path 6 do not overlap in the height direction, overlap in the length direction, and also overlap in the width direction.

[0084] Specifically, the overlap in the width direction means that the width of the first signal path 5 is greater than or equal to the width of the second signal path 6, so that when the electromagnetic wave transmitted by the first signal path 5 is transmitted to the second signal path 6, the leakage magnetic field is reduced as much as possible, thereby improving the transmission efficiency of the electromagnetic wave.

[0085] Based on any of the above embodiments, the first signal path 5 and the second signal path 6 are centrally symmetrical about the connection midpoint between the input end and the output end.

[0086] Please refer to Figure 1 , Figure 7 The first signal path 5 and the second signal path 6 are symmetrical about the center of the connection midpoint between the input end and the output end, and the length, width and height of the two signal paths are consistent.

[0087] On this basis, the first metal plate 3 and the second metal plate 4 are also centrally symmetrical structures, the first metal plate 3 and the first signal path 5 can be integrally formed, and the second metal plate 4 and the second signal path 6 can be integrally formed, which can ensure good electromagnetic transmission performance in practical applications. In addition, it is convenient to process the entire waveguide transmission part, simplify the processing flow, and reduce the processing cost. If local damage occurs during use, it does not need to be completely replaced, reducing the cost of use.

[0088] Based on any of the above embodiments, a plug-in interface 7 is provided in the first signal path 5 and the second signal path 6, the input waveguide structure 1 is plugged into the plug-in interface 7 in the second signal path 6, and the output waveguide structure 2 is plugged into the plug-in interface 7 in the first signal path 5.

[0089] Please refer to Figure 4 , Figure 5 The plug interface 7 is a non-through hole and is arranged in the signal path. The shape and size of the plug interface 7 are not limited.

[0090] The input waveguide structure 1 is plugged into the plug-in port 7 in the second signal path 6 on the second metal plate 4, and the output waveguide structure 2 is plugged into the plug-in port 7 in the first signal path 5 on the first metal plate 3, completing the plug-in of the waveguide transmission part, the input waveguide structure 1, and the output waveguide structure 2. This plug-in process can be based on the input waveguide structure 1, the output waveguide structure 2 before being connected to the electromagnetic device, and can also be based on the input waveguide structure 1, the output waveguide structure 2 after being connected to the electromagnetic device, specifically in combination with the position of the electromagnetic device, the spatial situation, etc.

[0091] In a specific embodiment, the first electromagnetic device is connected by the input waveguide structure 1, the second electromagnetic device is connected by the output waveguide structure 2, and then the input waveguide structure 1 and the output waveguide structure 2 are correspondingly plugged into the plug interface 7, so that the signal transmission between the two electromagnetic devices can be completed;

[0092] When it is necessary to disconnect the signal transmission and the connection between the two electromagnetic devices, the input waveguide structure 1 and the output waveguide structure 2 can be unplugged from the corresponding plug-in interface 7. The operation is simple and convenient and will not damage the input waveguide structure 1 or the output waveguide structure 2.

[0093] On the basis of any of the above embodiments, a closure member is provided at the top of the plug port 7, and the closure member can be rotated to close or open the closure member of the plug port 7;

[0094] A buffer is provided at the bottom of the plug port 7 .

[0095] In this embodiment, the buffer and the closing member may also be adaptively arranged. If the buffer cannot be arranged, such as due to space limitations or installation requirements, only the closing member may be arranged.

[0096] Specifically, a sealing member is provided on the top of the plug interface 7. When the input waveguide structure 1, the output waveguide structure 2, the first metal plate 3, and the second metal plate 4 are all independent components, if signal connection is not required, the plug interface 7 can be sealed by the sealing member to prevent impurities from entering and affecting the transmission of electromagnetic waves during subsequent use. Correspondingly, when signal connection is required, the sealing member can be rotated to open the plug interface 7.

[0097] Specifically, a buffer can be set at the bottom of the plug interface 7, which is mainly used for buffering when the input waveguide structure 1, the output waveguide structure 2 and the plug interface 7 are connected, to ensure the reliability and stability during plugging, and to avoid the problem of component damage caused by excessive plugging force.

[0098] On the basis of any of the above embodiments, the input waveguide structure 1 and the first metal plate 3 are integrally formed, and the output waveguide structure 2 and the second metal plate 4 are integrally formed.

[0099] Please refer to Figure 1 , Figure 7 The input waveguide structure 1 and the first metal plate 3 are integrally formed to form a monomer of the waveguide connection device, and the output waveguide structure 2 and the second metal plate 4 are integrally formed to form another monomer of the waveguide connection device. The structures of the two monomers are essentially the same. When applied to the connection of two electromagnetic devices, the two monomers can be assembled into a centrally symmetrical structure.

[0100] The specific one-piece forming method is stamping, and the input waveguide structure 1 and the first metal plate 3 are formed as an integrated part, and the output waveguide structure 2 and the second metal plate 4 are formed as an integrated part by stamping.

[0101] In this embodiment, an integrated molding method is used to improve the modular production of the electromagnetic waveguide connection structure. Specifically, it can be applied when it is convenient to connect the electromagnetic device and the input / output waveguide structure. The two monomers are first plugged and assembled, and then the input / output waveguide structure corresponding to the monomer is connected to the electromagnetic device.

[0102] Based on any of the above embodiments, the input waveguide structure 1 includes an input port 11 and a first waveguide transmission line 12 coaxially arranged therewith, and the first waveguide transmission line 12 passes through the first metal plate 3 and extends into the insertion port 7 .

[0103] Please refer to Figure 1 , Figure 4 The input waveguide structure 1 is specifically a coaxial waveguide. The input waveguide structure 1 includes an input port 11 and a first waveguide transmission line 12 coaxially arranged therewith. The input port 11 is arranged as a whole on the outside of the first metal plate 3, that is, outside the open transmission space. The first waveguide transmission line 12 is coaxially arranged with the input port 11 and is a closed waveguide outside the open transmission space.

[0104] The first waveguide transmission line 12 has a portion disposed in the input port 11, and also has a portion passing through the first metal plate 3 and extending into the insertion port 7 at the input end of the open transmission space. That is, the first metal plate 3 is provided with an opening for the first waveguide transmission line 12 to pass through, and the size of the opening is specifically to allow the first waveguide transmission line 12 to pass through on the basis of supporting the input port 11.

[0105] Taking one implementation mode as an example, a step hole is provided on the first metal plate 3, the aperture of the top of the step hole is adapted to the input port 11, the aperture of the bottom is smaller than the top aperture and larger than the diameter of the first waveguide transmission line 12, and the input waveguide structure 1 can be directly placed into the step hole to complete the matching connection with the first metal plate 3, and the connection is reliable and stable.

[0106] The specific size of the step hole and the size of the input waveguide structure 1 can be flexibly designed based on actual conditions, and no excessive restrictions are imposed here.

[0107] In this embodiment, the first waveguide transmission line 12 passes through the first metal plate 3 and extends into the plug-in port 7. The first waveguide transmission line 12 is extended into the plug-in port 7 so as to be in close contact with the inner wall of the plug-in port 7. Preferably, the first waveguide transmission line 12 is extended into the plug-in port 7 and in contact with the bottom of the inner wall of the plug-in port 7 to ensure the overall stability of the connecting device.

[0108] Based on any of the above embodiments, the output waveguide structure 2 includes an output port 21 and a second waveguide transmission line 22 coaxially arranged therewith, and the second waveguide transmission line 22 passes through the second metal plate 4 and extends into the insertion port 7 .

[0109] Please refer to Figure 1 , Figure 5As a specific implementation, the output waveguide structure 2 and the input waveguide structure 1 are centrally symmetrical structures. The output waveguide structure 2 is also specifically a coaxial waveguide. The output waveguide structure 2 includes an output port 21 and a second waveguide transmission line 22 coaxially arranged therewith. The output port 21 is entirely arranged on the outside of the second metal plate 4, that is, outside the open transmission space. The second waveguide transmission line 22 is coaxially arranged with the output port 21 and is a closed waveguide outside the open transmission space.

[0110] The second waveguide transmission line 22 passes through the second metal plate 4 and extends into the plug interface 7 at the output end of the open transmission space. Correspondingly, a step hole may also be provided on the second metal plate 4. The aperture at the top of the step hole is adapted to the output port 21, and the aperture at the bottom is smaller than the top aperture and larger than the diameter of the second waveguide transmission line 22. The output waveguide structure 2 can be directly placed into the step hole to complete its mating connection with the second metal plate 4, and the connection is reliable and stable.

[0111] In this embodiment, the second waveguide transmission line 22 passes through the second metal plate 4 and extends into the plug-in port 7. The first waveguide transmission line 12 is extended into the plug-in port 7 to make close contact with the inner wall of the plug-in port 7. Preferably, the second waveguide transmission line 22 is extended into the plug-in port 7 and contacts with the bottom of the inner wall of the plug-in port 7 to ensure the overall stability of the connecting device.

[0112] In combination with the above embodiments, the electromagnetic waveguide connection structure provided by the present invention is tested in actual application:

[0113] like Figure 1 As shown, the input waveguide structure 1 is connected to the first electromagnetic device and extends into the plug-in port 7 on the second metal plate 4, and the output waveguide structure 2 is connected to the second electromagnetic device and extends into the plug-in port 7 on the first metal plate 3. After plugging, a simulation test is performed.

[0116] In this embodiment, the second metal plate 4 is provided with a vertically arranged guide structure, and the first metal plate 3 is provided with a positioning block extending into the guide structure to cooperate with the guide structure for guidance; or the first metal plate 3 is provided with a vertically arranged guide structure, and the second metal plate 4 is provided with a positioning block extending into the guide structure to cooperate with the guide structure for guidance. Both of these situations can be applied to the guidance when the input waveguide structure 1 and the output waveguide structure 2 are plugged in, so that the connection device can adapt to more models and has stronger applicability.

[0117] Taking a specific implementation as an example, a guide structure, such as a guide slot, is provided on the second metal plate 4, and a positioning block that can slide along the guide slot is provided on the first metal plate 3. The input waveguide structure 1 is first plugged into the first metal plate 3, and then its positioning block is extended into the guide slot, and the overall structure of the input waveguide structure 1 and the first metal plate 3 is pushed downward until the input waveguide structure 1 is accurately plugged into the plug-in port 7 on the second metal plate 4.

[0124] Taking a specific implementation as an example, a positioning column 8 is set on the second metal plate 4. The height of the positioning column 8 can be set according to the specific situation when the actual electromagnetic device is docked. On the one hand, the positioning column 8 limits the distance between the first metal plate 3 and the second metal plate 4 to a certain extent; on the other hand, the positioning column 8 and the non-through hole can ensure the reliable stability of the input / output waveguide structure and the structure after the two metal plates are connected, ensuring a stable and reliable connection. The setting here can be integrated to meet the needs of modular production and improve production efficiency.

[0125] There is no restriction on the distribution and number of specific positioning columns 8, and they can be flexibly set according to different usage requirements, different processing requirements, and different operating cost requirements without excessive restrictions.

[0126] In a specific embodiment, the positioning column 8 can be provided with several groups of different heights.
