Technical Field

[0001] The present invention relates to the field of electromagnetic acceleration, and in particular to an electromagnetic acceleration coil module and an electromagnetic acceleration launch device. Background Art

[0002] Coil-type electromagnetic acceleration technology is a modern acceleration technique that converts electrical energy into electromagnetic energy to achieve a specified speed. It boasts advantages such as smoke-free and noiseless acceleration, excellent concealment, and adjustable exit velocity and range. It has become a hot topic of research both domestically and internationally in recent years. Existing coil-type electromagnetic acceleration devices, such as the electromagnetic launch device disclosed in Chinese Utility Model Application Publication No. CN216898544U, comprise an accelerating coil module and a guide cylinder disposed axially forward of the accelerating coil module. The accelerating coil module includes a drive coil for generating electromagnetic force. A transmitting armature is disposed within the drive coil. The electromagnetic force generated by the drive coil causes the transmitting armature to move linearly along the axis of the drive coil, propelling the load at high speed. The guide cylinder guides the load as it exits the coil.

[0003] The acceleration coil module of the existing electromagnetic launch device can only launch loads of matching caliber. For different types of loads, the launch device can only be replaced as a whole. It is impossible to achieve simultaneous acceleration of different types of loads and cannot meet the requirements of launch diversity and high efficiency. Summary of the Invention

Furthermore, the present invention aims to provide an electromagnetic acceleration launch device to address the problem that existing electromagnetic acceleration launch devices cannot meet the need for launching multiple different payload types.

[0005] The electromagnetic acceleration coil module of the present invention includes a module shell, in which a plurality of acceleration coils are installed. The plurality of acceleration coils are arranged side by side in a plane perpendicular to the axis of the acceleration coil. The side of the module shell located in the axial direction of the acceleration coil is used to configure a guide cylinder of a load guide structure. The electromagnetic acceleration coil module is configured with different drive armatures for guide cylinders of different calibers. The drive armature includes a pivot rod for inserting into the inner hole of the acceleration coil and cooperating with the acceleration coil, and also includes a pushing portion at the end of the pivot rod for pushing the load. Different drive armatures contain different numbers of pivot rods, so that loads of different calibers can be driven and accelerated by different numbers of acceleration coils.

[0006] Furthermore, the cross-sectional shape and size of each accelerating coil are the same.

[0007] Furthermore, all the accelerating coils are tightly packed in the module housing.

[0008] Furthermore, the accelerating coil is a hollow regular hexagonal prism structure.

[0009] Furthermore, among the acceleration coils arranged in the module housing, a space is left in the middle of the six acceleration coils arranged circumferentially to form a heat dissipation and wiring channel for the acceleration coils.

[0010] The present invention provides a new electromagnetic acceleration coil module in a pioneering manner. The coil module arranges a certain number of acceleration coils in parallel within the module housing, which are matched with different drive armatures. Each drive armature has a common push portion but has a pivot rod portion that matches a different number of acceleration coils. In this way, different drive armatures can match different numbers of drive coils to generate acceleration driving forces of different sizes.

[0027] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0028] The electromagnetic acceleration launch device of the present invention improves the existing launch device by upgrading the electromagnetic acceleration coil module, reducing the acceleration coil from integral to zero, arranging a certain number of acceleration coils in parallel in the module housing, and cooperating with different drive armatures. Each drive armature has a common push portion but has a pivot portion that cooperates with a different number of acceleration coils. In this way, different drive armatures can cooperate with different numbers of drive coils to generate acceleration driving forces of different sizes. In this way, no matter what kind of acceleration load is targeted, the only difference in the number of drive coils that the coil module provides driving force to is that the coil module can drive different types of acceleration loads in combination with different drive armatures, thereby improving the launch capability of the electromagnetic acceleration launch device as a whole.

[0029] Specifically, based on such inventive concept, a variety of different embodiments are provided below for illustration.

[0030] like Figure 1-2 As shown, in an embodiment of an electromagnetic acceleration launch device, it includes an electrical control cabinet 2 and an electromagnetic acceleration coil module 1. A load guide structure is configured on one side of the electromagnetic acceleration coil module 1. The electrical control cabinet 2 is provided with a power supply module and a control module. The power supply module is used to supply power to the electromagnetic acceleration coil module 1, the control module is used to control the operating state of the electromagnetic acceleration coil module 1, and the load guide structure is used to guide the acceleration load to ensure the accuracy of its launch direction. These are no different from existing launch devices and will not be further described in this article. The key difference between the present invention and the prior art lies in the overall design of the electromagnetic acceleration coil module 1.

[0031] like Figure 2-5 As shown, the electromagnetic acceleration coil module 1 includes a module shell, which includes a circumferentially enclosed main shell. The main shell forms an installation cavity inside, in which the acceleration coil 10 is installed, and the axial direction of the acceleration coil 10 is consistent with the axial direction of the main shell. The cross-sectional shape of the main shell can be circular, rectangular, or other polygonal, depending on the actual use requirements. In the embodiment shown in the figure, the cross-sectional shape of the main shell is rectangular. The module shell also includes a rear sealing plate at one axial end of the main shell, and a load guide structure is configured at the other end of the main shell. The load guide structure includes a fixed base plate and a guide cylinder 5 installed on the front side of the fixed base plate. The fixed base plate is used to be fixed to the front end of the main shell. The guide cylinder 5 is used to guide the acceleration load. The driving armature is acted upon by the acceleration coil 10 to move in a straight line at high speed, and can push the acceleration load in the guide cylinder 5 along the guide cylinder 5. The acceleration coil 10 is located in the space surrounded by the main shell, the rear sealing plate, and the fixed base plate.

[0032] The acceleration coils 10 within the main housing are arranged in parallel in a plane perpendicular to the axis of the acceleration coils 10. A predetermined number of these coils are arranged according to a specific pattern (e.g., a circular array, a rectangular array, or other pattern). The guide cylinders 5 of the load guide structure can be provided as needed, with one or more of them. The diameter of each guide cylinder 5 varies depending on the type of acceleration load. However, it must be ensured that the axial projection of each guide cylinder 5 is covered by an acceleration coil 10; however, the number of acceleration coils 10 may vary depending on the diameter of the guide cylinder 5.

[0033] The electromagnetic acceleration coil module 1 is configured with different drive armatures for guide tubes 5 of different calibers. The drive armature includes a pivot rod 51 for inserting into the coil inner hole 100 of the acceleration coil 10 and cooperating with the acceleration coil 10. It also includes a pushing portion at the end of the pivot rod 51 for pushing the load. Because the number of acceleration coils 10 corresponding to guide tubes 5 of different calibers may vary, different drive armatures also contain different numbers of pivot rods 51. In this way, guide tubes 5 of different calibers, that is, loads of different calibers, can be driven and accelerated by different numbers of acceleration coils 10 to meet the load's launch requirements.

[0034] Figure 6-9 That is, four different types of drive armatures are provided. The four types of drive armatures are respectively suitable for four different diameter guide cylinders 5. Figure 2 As shown, the guide tube 5 in the load guide structure has the smallest diameter, and its axial direction corresponds to an accelerating coil 10. For the accelerating load in the guide tube 5, the driving armature used is Figure 6 The rod-shaped armature shown in FIG. When in use, the driving armature is inserted into the inner hole of the corresponding accelerating coil 10, and the front end extends out of the accelerating coil 10 and into the guide tube 5, and the rod end surface 52 constitutes a pushing portion for directly pushing the accelerating load for launch.

[0035] like Figure 2 As shown, some guide cylinders 5 in the load guide structure have larger diameters, and their axial directions correspond to two or three extending to four accelerating coils 10. For the accelerating loads in these guide cylinders 5, the driving armatures used are respectively Figure 7 、 Figure 8 、 Figure 9 The drive armature shown in the figure. A common feature of this type of drive armature is that, during use, each pivot rod 51 is inserted into the coil inner hole 100 of the corresponding acceleration coil 10. A circular push plate 53 is connected to the front end of each pivot rod 51. This push plate is located within the guide cylinder 5. This push plate 53 forms a push portion for directly pushing the acceleration load for launch. In practice, the number of pivot rods 51 in the drive armature will be determined by the number of acceleration coils 10 corresponding to the axial direction of the guide cylinder 5.

[0036] The cross-sectional shape of the acceleration coil 10 installed in the main shell can be the most traditional circle, or a square, or other regular polygons. The square or other regular polygon acceleration coil 10 is mainly a unique design of the casting shape when pouring the insulating material on the outside of the wound coil, using a mold with a molding surface as the direction or other regular polygon. Some of the acceleration coils 10 may have the same cross-sectional shape and radial size, while some may have different cross-sectional shapes and radial sizes. In one embodiment, the cross-sectional shape and radial size of the acceleration coils 10 installed in the main shell are the same, so that the arrangement of each acceleration coil 10 in the main shell is easier to ensure uniformity, and the cost of disassembly and assembly or manufacturing of the acceleration coil 10 is relatively low, and the interchangeability is better when replacing the acceleration coil 10.

[0037] The acceleration coils 10 can be fixed in the main housing by providing a fixed frame in the main housing and fixing the acceleration coils 10 one by one to the fixed frame, or by gluing the entire acceleration coils 10 after arranging them in the main housing. In a preferred embodiment, all the acceleration coils 10 are tightly packed in the main housing. That is, after all the acceleration coils 10 are packed in the main housing one by one, they are squeezed and fixed to each other. In this way, they only need to be pulled out axially during disassembly, which is convenient for assembly and disassembly. Moreover, the inner cavity of the main housing can be fully utilized as much as possible to install the acceleration coils 10. The acceleration coils 10 are arranged more densely and evenly, and the number, diameter and position of the guide cylinders 5 of the load guide structure can be set more flexibly.

[0038] Based on the above embodiments, in a preferred embodiment, the acceleration coil 10 is a hollow regular hexagonal prism. Thus, after being tightly packed within the main housing, the acceleration coils 10 can be supported and positioned by adjacent acceleration coils 10, ensuring that all acceleration coils 10 within the entire main housing are in a stable state. This ensures the stability of the acceleration coils 10 without relying on other retaining and positioning structures. Of course, in other embodiments, based on the same principle, the outer contour of the acceleration coil 10 can also be prismatic, with the side surfaces of adjacent acceleration coils 10 supporting and fitting together to achieve positioning and retention.

[0039] Considering that the acceleration coil 10 needs to lead out wires, and the acceleration coil 10 is not just one group in the axial direction, in most cases the acceleration coil 10 often includes multiple groups arranged coaxially. At this time, in order to facilitate the lead-out of the multiple coaxial groups of acceleration coils 10, it is necessary to reserve spaces 11 between the acceleration coils 10 arranged in parallel in the main housing. In this case, it is preferred to use a hollow regular hexagonal prism-shaped acceleration coil 10, such as Figure 3As shown, among the six accelerator coils 10 arranged circumferentially within the module housing, spaces 11 are left between them to form heat dissipation and wiring channels for the accelerator coils 10. This not only creates heat dissipation and wiring channels, but also ensures that all accelerator coils 10 remain stable.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall be included in the scope of protection of the present invention.
