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 transmitting device. Background Art

[0002] Coil-type electromagnetic acceleration technology is a modern acceleration technology that converts electrical energy into electromagnetic energy to make an object reach a specified speed. It has the advantages of no smoke and noise during the acceleration process, good concealment, and adjustable exit speed and range. It has become a hot topic of research at home and abroad in recent years. The existing coil-type electromagnetic acceleration device is shown in an electromagnetic launch device disclosed in the Chinese utility model application with application publication number CN216898544U. The electromagnetic launch device includes an acceleration coil module and a guide cylinder, which is arranged on the axial front side of the acceleration coil module. The acceleration coil module includes a driving coil for generating electromagnetic force. A launching armature is arranged inside the driving coil. The launching armature moves linearly along the axis direction of the driving coil under the action of the electromagnetic force generated by the driving coil. The launching armature pushes the load to move at high speed, and the guide cylinder is used to guide the load to exit the cylinder.

[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 diversification and high efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide an electromagnetic acceleration coil module to solve the problem that the existing electromagnetic acceleration coil can only launch loads with matching calibers and cannot meet the needs of launching multiple types of different loads. At the same time, the purpose of the present invention is also to provide an electromagnetic acceleration launch device to solve the problem that the existing electromagnetic acceleration launch device cannot meet the needs of launching multiple types of different loads.

[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. One side of the module shell on 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 driving armatures for guide cylinders of different calibers. The driving 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 driving armatures include 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 in a module shell, which cooperate with different drive armatures. Each drive armature has a common push portion but has an armature 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.

[0019] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0020] 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 shell, and cooperating with different drive armatures. Each drive armature has a common push portion but has a pivot rod 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 drive coils that the coil module provides driving force for it are only different in number, so 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.

[0021] Specifically, based on such inventive concept, a variety of different embodiments are provided below for illustration.

[0022] like Figure 1-2 As shown, in an embodiment of an electromagnetic acceleration launch device, it includes an electric control cabinet 2 and an electromagnetic acceleration coil module 1, one side of the electromagnetic acceleration coil module 1 is provided with a load guide structure, and the electric control cabinet 2 is provided with a power supply module and a control module, wherein the power supply module is used to supply power to the electromagnetic acceleration coil module 1, the control module is used to control the working 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 the existing launch devices, and will not be further elaborated in this article. The key difference between the present invention and the prior art is the overall design of the electromagnetic acceleration coil module 1.

[0023] like Figure 2-5 As shown, the electromagnetic acceleration coil module 1 includes a module housing, which includes a circumferentially enclosed main housing, an installation cavity is formed inside the main housing, an acceleration coil 10 is installed in the installation cavity, and the axial direction of the acceleration coil 10 is consistent with the axial direction of the main housing. The cross-sectional shape of the main housing 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 housing is rectangular. The module housing also includes a rear sealing plate at one axial end of the main housing, and a load guiding structure is configured at the other end of the main housing. The load guiding structure includes a fixed substrate and a guide cylinder 5 installed on the front side of the fixed substrate. The fixed substrate is used to be fixed on the front end of the main housing, and the guide cylinder 5 is used to guide the acceleration load. The driving armature is subjected to the action of the acceleration coil 10 and moves in a straight line at high speed, and the acceleration load in the guide cylinder 5 can be pushed out along the guide cylinder 5. The acceleration coil 10 is in the space surrounded by the main housing, the rear sealing plate and the fixed substrate.

[0024] The acceleration coils 10 in the main housing are arranged in parallel in a plane perpendicular to the axis of the acceleration coils 10, with a certain number, and arranged according to a certain rule (such as a circular array or a rectangular array or other rules). The guide cylinders 5 of the load guide structure can be set as needed, the number can be one or more, and the caliber depends on the type of acceleration load. The calibers of different guide cylinders 5 can be different. However, it must be ensured that the axial projection of each guide cylinder 5 is covered with an acceleration coil 10, but the number of acceleration coils 10 corresponding to guide cylinders 5 of different calibers may be different.

[0025] The electromagnetic acceleration coil module 1 is configured with different driving armatures for guide cylinders 5 of different calibers. The driving 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, and also includes a pushing portion for pushing the load at the end of the pivot rod 51. Because the number of acceleration coils 10 corresponding to guide cylinders 5 of different calibers may be different, the number of pivot rods 51 included in different driving armatures is also different. In this way, guide cylinders 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 launch requirements of the load.

[0026] 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 caliber guide tubes 5. Figure 2 As shown, in the load guide structure, a portion of the guide cylinder 5 has the smallest diameter, and its axial direction corresponds to an acceleration coil 10. For the acceleration load in the guide cylinder 5, the driving armature used is Figure 6 The rod-shaped armature shown in the figure is driven to be inserted into the inner hole of the corresponding accelerating coil 10 when in use, and the front end thereof extends out of the accelerating coil 10 and into the guide tube 5, and the rod end surface 52 thereof constitutes a pushing portion for directly pushing the accelerating load for launching.

[0027] 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 acceleration coils 10. For the acceleration loads in these guide cylinders 5, the driving armatures used are respectively Figure 7 , Figure 8 , Fig. 9 The driving armature shown in the figure. The common feature of this type of driving armature is that when in use, each pivot rod 51 is respectively inserted into the coil inner hole 100 of the corresponding acceleration coil 10, and the front end of all the pivot rods 51 is connected to a circular push plate, which is located in the guide cylinder 5. The push plate 53 constitutes a push portion for directly pushing the acceleration load for launching. In fact, the number of pivot rods 51 is the same as the number of acceleration coils 10 corresponding to the axial direction of different guide cylinders 5.

[0028] 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 outside the wound coil, using a mold with a molding surface as a direction or other regular polygon. Some of the acceleration coils 10 may have the same cross-sectional shape and radial size, and 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, whether it is the disassembly and assembly or the manufacturing of the acceleration coil 10, the cost is relatively low, and when replacing the acceleration coil 10, the interchangeability is better.

[0029] The acceleration coil 10 can be fixed in the main shell by setting a fixed frame in the main shell and fixing the acceleration coils 10 one by one to the fixed frame, or by gluing the whole after arranging them in the main shell. In a preferred embodiment, all the acceleration coils 10 are tightly packed in the main shell, that is, after all the acceleration coils 10 are filled in the main shell one by one, they are squeezed and fixed to each other, so that they only need to be pulled out axially during disassembly, which is convenient for disassembly and assembly. Moreover, the inner cavity of the main shell arranged in this way can be fully utilized as much as possible to install the acceleration coils 10, and the acceleration coils 10 are arranged more densely and evenly, and the number, caliber and position of the guide tubes 5 of the load guide structure will be more flexible.

[0030] Based on the above embodiments, in a preferred embodiment, the acceleration coil 10 is a hollow regular hexagonal prism structure, so that after being tightly plugged into the main housing, it can rely on the mutual support and positioning between adjacent acceleration coils 10 to ensure that all acceleration coils 10 in the entire main housing are in a stable state, and the stability of the acceleration coil 10 can be ensured without relying on other retaining and positioning structures. Of course, in some other embodiments, based on the same principle, the outer contour of the acceleration coil 10 can also be a prism, relying on the mutual support of the sides of adjacent acceleration coils 10 to achieve positioning and retention.

[0031] 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 groups of coaxial acceleration coils 10, it is necessary to reserve a space 11 between the acceleration coils 10 arranged in parallel in the main housing. At this time, it is preferred to use a hollow regular hexagonal prism-shaped acceleration coil 10, such as Figure 3As shown, among the acceleration coils 10 arranged in the module housing, a space 11 is left in the middle of the six acceleration coils 10 arranged circumferentially to form a heat dissipation and wiring channel for the acceleration coils 10. In this way, a heat dissipation and wiring channel can be formed, and all the acceleration coils 10 can be kept in a stable state by relying on the acceleration coils 10.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the contents of the description and drawings of the present invention should also be included in the protection scope of the present invention.
