It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Firstly, please refer to Figures 1 to 2 As shown, this utility model embodiment provides a closed-loop moving magnet electromagnetic catapult device, including a stator coil mechanism 100, a moving magnet mechanism 200 and at least one guide component 300. The moving magnet mechanism 200 is sleeved on the stator coil mechanism 100 and connected to the stator coil mechanism 100 through the guide component 300, and moves relative to the stator coil mechanism 100 along the length direction of the stator coil mechanism 100.

[0028] The stator coil mechanism 100 in this embodiment is generally a long strip-shaped block, plate, or frame structure, which is used to be placed on a foundation, mobile platform, vehicle, etc. The stator coil mechanism 100 has a slide along the length direction, and the power supply cable can be arranged inside the stator coil mechanism 100.

[0029] In this embodiment, the moving magnet mechanism 200 is generally hollow, block-shaped, frame-shaped, or similar to a sleeve. When the stator coil mechanism 100 is energized, the moving magnet mechanism 200 and the stator coil mechanism 100 generate driving or braking forces due to magnetic force. The upper surface of the moving magnet mechanism 200 is used to place the ejected material.

[0030] The guide component 300 in this embodiment can be composed of components such as roller assembly, slider and guide rail, and is used to provide guidance along a straight direction.

[0031] Specifically, the moving magnet mechanism 200 is fitted onto the stator coil mechanism 100, and the guide component 300 is set on the stator coil mechanism 100, with the guide direction consistent with the slide direction. The moving magnet mechanism 200 forms a stable moving connection with the stator coil mechanism 100 through the guide component 300.

[0032] In this way, compared with the existing open-type and open-type mover structures, the application of the closed-loop moving magnet electromagnetic catapult device provided by this utility model embodiment, through the mover magnet mechanism 200 forming a circumferentially enclosing closed structure on a section of the stator coil mechanism 100 along the length direction, can greatly improve the structural strength of the mover magnet mechanism 200, the force transmission path is more reasonable and balanced, the gap between it and the stator coil mechanism 100 is consistent during the movement, the catapult performance is more stable and reliable, the power supply cable is arranged inside the stator coil mechanism 100, there is no problem of poor contact when powering through the sliding contact line, it is easy to maintain, the manufacturing cost is lower, and the investment benefit is higher.

[0033] In some embodiments, the mover magnet mechanism 200 includes a frame assembly 210 and a plurality of mover magnets 220. The frame assembly 210 is sleeved on the stator coil mechanism 100 and connected to the stator coil mechanism 100 through a guide assembly 300.

[0034] The stator coil mechanism 100 has moving magnets 220 arranged on both sides along the height or width direction, and the moving magnets 220 are connected to the inner wall of the frame assembly 210.

[0035] Specifically, such as Figure 1 , Figure 2 As shown, the cross-section of the frame assembly 210 is roughly rectangular or a regular polygon, and each surface of the frame assembly 210 is roughly parallel to the adjacent surface of the stator coil mechanism 100. This makes the force transmission path more reasonable.

[0036] For example, such as Figure 1 As shown, the suction forces on the left and right sides act on the upper and lower supports of the frame component 210. The internal forces of the upper and lower supports counteract the suction forces on the left and right sides, and will not exert lateral forces on the guide component 300 in the left and right directions. The guide component 300 only provides vertical support. Even if there is a slight imbalance in the suction forces on the left and right sides, the lateral force acting on the guide component 300 after counteracting is extremely small, thereby greatly reducing the movement resistance and making the structure more stable.

[0037] The moving magnet 220 can include a coreless or cored structure. Alternatively, the moving magnet 220 can be arranged vertically on both sides of the stator coil mechanism 100, and correspondingly, the guide assembly 300 can be arranged horizontally on both sides of the stator coil mechanism 100, depending on actual needs. Furthermore, by connecting the moving magnet 220 to the inner wall of the frame assembly 210, the structure becomes more compact. If necessary, a shielding layer can be provided around the closed-loop moving magnet electromagnetic catapult device. The shielding layer can be fixedly installed at both ends of the stator coil mechanism 100, leaving only a slot for the catapult frame to slide, to reduce outward magnetic radiation.

[0038] Furthermore, in this embodiment, the frame assembly 210 includes a first mounting plate 211 and a second mounting plate 212. The first mounting plate 211 is arranged on both sides of the stator coil mechanism 100 along the height direction, and the first mounting plate 211 is connected to the stator coil mechanism 100 through the guide assembly 300.

[0039] Second mounting plates 212 are respectively arranged on both sides of the stator coil mechanism 100 along the width direction, and the second mounting plates 212 are connected to the adjacent first mounting plates 211. Moving magnets 220 are respectively arranged on both sides of the stator coil mechanism 100 along the width direction, and the moving magnets 220 are connected to the inner wall of the corresponding second mounting plates 212.

[0040] For example, such as Figure 1 As shown, the frame assembly 210 has a rectangular or square cross-section. The frame assembly 210 includes two upper and lower first mounting plates 211 and two left and right second mounting plates 212. The four plates are sequentially fixed together by welding or screwing. The first mounting plates 211 are connected to the stator coil mechanism 100 via a guide assembly 300. The mover magnet 220 can be fixed to the inner wall of the corresponding second mounting plate 212 by screwing or welding. The above two-part assembly structure facilitates single-piece processing and subsequent assembly, meeting the needs of large-scale rapid production.

[0041] Furthermore, in this embodiment, a positioning structure is provided between the second mounting plate 212 and the first mounting plate 211.

[0042] For example, such as Figure 1 As shown, the inner wall of the first mounting plate 211 has a positioning groove, and the side of the second mounting plate 212 facing the positioning groove matches and positions itself with the positioning groove. This ensures the stability of the connection between the second mounting plate 212 and the first mounting plate 211 and avoids relative displacement during use. Of course, other types of positioning structures can also be used instead, depending on actual needs. This embodiment does not impose too many restrictions.

[0043] And / or, a reinforcing member is provided at the connection between the second mounting plate 212 and the first mounting plate 211.

[0044] That is, reinforcing blocks or ribs can be provided at the corner connection between adjacent second mounting plates 212 and first mounting plates 211 to further increase structural strength. Furthermore, at least one of the first mounting plates 211 and second mounting plates 212 has a weight-reducing section. This weight-reducing section can be a weight-reducing hole, a weight-reducing groove, etc., and both the first mounting plate 211 and second mounting plate 212 can be provided with such weight-reducing holes or grooves, which can significantly reduce the total weight of the mover magnet mechanism 200, thereby enabling the ejection of heavier materials. This can be determined according to actual needs, and this embodiment does not impose excessive restrictions.

[0045] In some embodiments, the guide assembly 300 includes a plurality of rollers, and the rollers are spaced apart on the inner walls of the first mounting plate 211 and / or the second mounting plate 212 along the length, width and height directions. Each roller makes rolling contact with the outer wall of the stator coil mechanism 100 and is limited along the width and height directions.

[0046] That is, such as Figure 1 As shown, rollers are arranged at all four corners of the stator coil mechanism 100, and so on. Figure 2 As shown, rollers at the four corners of the stator coil mechanism 100 are spaced apart along the length direction, thereby limiting the stator coil mechanism 100 in the width and height directions, allowing it to reciprocate only along the length direction. The rollers can be connected to the inner walls of the first mounting plate 211 and / or the second mounting plate 212 via a rotating shaft. The specifications, quantity, and installation position of the rollers can be determined according to actual needs.

[0047] Of course, other types of guide components can be used instead, depending on the actual needs. This embodiment does not impose too many restrictions. It is sufficient to ensure that there is enough space between the middle of the stator coil mechanism 100 and the corresponding first mounting plate 211 for installing the sensor.

[0048] Furthermore, in this embodiment, limiting grooves 101 are provided on opposite sides of the stator coil mechanism 100, and roll in cooperation with adjacent rollers to limit movement along the width and height directions.

[0049] Specifically, such as Figure 1 As shown, two limiting grooves 101 on the stator coil mechanism 100 are arranged on both sides along the width direction, and their opening directions are opposite. Correspondingly, two rollers are arranged at intervals along the width direction on the inner wall of the first mounting plate 211. The axis of the rollers is arranged in the vertical direction. The rollers roll in the limiting grooves 101 to achieve stable limiting in the width and height directions. The structure is simple, reliable and easy to process.

[0050] It should be noted that only one limiting groove 101 needs to be arranged along the height direction, such as... Figure 1 As shown, the lower roller does not need to be equipped with a limit groove 101 to avoid repeated positioning or interference.

[0051] In some embodiments, the stator coil mechanism 100 includes a profile frame 110, a plurality of connectors 120 and a plurality of stator coils 130, with connectors 120 respectively connected to both sides of the profile frame 110 along the height direction.

[0052] Stator coils 130 are arranged on both sides of the profile frame 110 along the width direction, and the stator coils 130 are connected to adjacent connectors 120. The guide assembly 300 is connected to the corresponding connector 120 on the side away from the profile frame 110.

[0053] Specifically, such as Figure 1 As shown, the profile frame 110 can be made of aluminum profile, which can significantly reduce weight. The connector 120 can be a connecting plate, and its cross-section can be I-shaped, straight, etc. The two connectors 120 can be fixed to the upper and lower surfaces of the profile frame 110 by screwing, welding, etc. The two stator coils 130 can be fixed to the left and right sides of the connector 120 by screwing, welding, etc. The two rollers can roll in contact with the corresponding connectors 120 on both sides along the width direction, that is, the limiting groove 101 can be located on the connector 120, which facilitates single-piece processing and subsequent assembly.

[0054] In some embodiments, the closed-loop moving-magnetic electromagnetic catapult device provided in this utility model embodiment further includes: The detection assembly 400 includes a detection sensor 410 and a detection strip 420. The detection strip 420 is provided on the inner wall of the first mounting plate 211, and the detection sensor 410 is correspondingly provided on the connector 120 to detect the relative position of the stator coil mechanism 100 and the mover magnet mechanism 200.

[0055] Specifically, such as Figure 1 , Figure 2As shown, the detection sensor 410 cooperates with the detection strip 420 to detect the relative position of the stator coil mechanism 100 and the mover magnet mechanism 200. For example, the detection sensor 410 can be a magnetoelectric sensor, and the detection strip 420 can be a magnetic strip. The detection sensor 410 can be mounted on the connector 120 of the stator coil mechanism 100, facing the side corresponding to the first mounting plate 211. The detection strip 420 can be fixed to the first mounting plate 211 by means of screwing, welding, etc. The length direction of the detection strip 420 is consistent with the moving direction, so that the position can be detected in real time. The specific type, specifications, quantity, and installation position of the detection sensor 410 and the detection strip 420 can be determined according to actual needs, and no excessive restrictions are imposed in this embodiment.

[0056] Furthermore, in this embodiment, the closed-loop moving magnet electromagnetic catapult device provided by this utility model has baffles 102 on both sides of the stator coil mechanism 100 along the width direction, and the detection sensor 410 is located between the two baffles 102.

[0057] Specifically, such as Figure 1 As shown, baffles 102 are provided on both sides of the upper surface of the connector 120 along the width direction. This protects the detection sensor 410 and prevents external factors from affecting its detection. The specific type, specifications, and installation position of the baffles 102 can be determined according to actual needs, and are not specifically limited in this embodiment.

[0058] And / or, the stator coil mechanism 100 is provided with a groove 103 for the detection sensor 410 to pass through the connecting wire.

[0059] Specifically, such as Figure 1 As shown, a wire groove 103 can also be provided on the lower surface of the connector 120 to facilitate the detection sensor 410 passing through it, thereby separating it from the power supply cable of the coil, reducing interference, and improving reliability. The specific type, specifications, and installation position of the wire groove 103 can be determined according to actual needs, and are not specifically limited in this embodiment.

[0060] Secondly, such as Figure 3 As shown, this utility model embodiment also provides a closed-loop moving-magnetic electromagnetic catapult method, applied to the closed-loop moving-magnetic electromagnetic catapult device in any of the above embodiments, including the following steps: S100, a drive current is supplied to the stator coil mechanism 100 so that the mover magnet mechanism 200 moves faster on the stator coil mechanism 100.

[0061] Specifically, an external power supply device (such as a frequency converter) can be used to supply drive current to the stator coil mechanism 100. The drive current causes the mover magnet mechanism 200 to accelerate on the stator coil mechanism 100, thereby providing an initial velocity for the ejected material.

[0062] S200: After the mover magnet mechanism 200 moves to the specified speed, a braking current is supplied to the stator coil mechanism 100 so that the mover magnet mechanism 200 decelerates and stops on the stator coil mechanism 100.

[0063] Specifically, after the moving magnet mechanism 200 moves to the specified speed, the ejected material is thrown out by inertia. At this time, the stator coil mechanism 100 can be supplied with braking current by an external power supply device to make the moving magnet mechanism 200 brake quickly and avoid sliding out of the slide on the stator coil mechanism 100.

[0064] Therefore, the closed-loop moving magnet electromagnetic catapult method provided by this utility model embodiment forms a circumferentially enclosing closed structure on a section of the stator coil mechanism 100 along its length by the moving magnet mechanism 200, which can greatly improve the structural strength of the moving magnet mechanism 200, make the force transmission path more reasonable and balanced, ensure good consistency of the gap between the moving magnet mechanism 200 and the stator coil mechanism 100 during the movement, make the catapult performance more stable and reliable, and the power supply cable is arranged inside the stator coil mechanism 100, so there is no problem of poor contact when powering through the sliding contact line, which is convenient for maintenance, has low manufacturing cost, and high investment efficiency.

[0065] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
