Description

Technical Field

[0001] The utility model relates to the technical field of recoil simulation devices, in particular to a multi-electromagnetic recoil device. Background Technique

[0002] With the development of VR industry technology, more and more VR products are integrated into military training. Currently, military training firearms cannot simulate real shooting. Real firearms will generate a certain intensity of recoil when shooting. In order to enhance the shooting experience, some toy guns or imitation guns will design certain devices to simulate this effect to increase the fun and authenticity when players are shooting;

[0003] The Chinese published patent (Publication No.: CN219284100U) discloses an electromagnet for simulating recoil effect, which includes a housing. The two ends of the housing are horizontally sleeved with an iron top cover and a copper top cover. A winding frame is horizontally sleeved inside the housing. A coil is horizontally wound in the outer wall groove of the winding frame. The coil is composed of three sections and is distributed horizontally. A push rod is horizontally sleeved inside the winding frame. The side end of the push rod horizontally penetrates through the middle of the copper top cover, and a permanent magnet is sleeved at the other end of the push rod. By setting this kind of circular iron tube electromagnet with a similar magnetic levitation effect, through the electromagnetic force generated by the permanent magnet on the outer wall of the push rod and the coil after being energized, the push rod is pushed to hit the copper top cover to simulate the recoil of a gunshot. The action is very fast, the volume is small, it is convenient to install, and the control is simple and accurate. It can relatively realistically simulate the recoil effect generated when a firearm shoots. However, in the actual use process, it can only simulate the recoil when a firearm shoots, and the functionality is relatively single. It cannot count the number of bullets when a firearm shoots, resulting in inconvenience for players to view the fired bullets and the remaining number of bullets, reducing the experience of players. Therefore, a multi-electromagnetic recoil device is proposed. Summary of the Utility Model

[0021] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0022] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown, the embodiment of the utility model provides a multi-electromagnetic recoil device, including a gun body 1 and a recoil mechanism 2;

[0024] The gun body 1 also includes a gun body 11, a recoil mechanism 2 is installed inside the gun body 11, and the recoil mechanism 2 also includes a copper tube 21, four permanent magnets 22 are fixedly connected to the inner wall of the copper tube 21, four coils 23 are wound around the outside of the copper tube 21, a Hall sensor 28 is installed on the outer wall of the coil 23, and a PLB board 29 is installed on the top of the Hall sensor 28.

[0025] In one embodiment, the copper wires between the four coils 23 are connected end to end, and the winding directions of the four coils 23 are respectively forward, reverse, forward, and reverse staggered winding; the four coils 23 are arranged in a staggered arrangement of forward and reverse winding, and the current flows in opposite directions after power is turned on, so that the electromagnetic poles generated by two adjacent coils 23 are in opposite directions, interacting with the permanent magnet 22 in the copper tube 21 to generate multi-stage thrust, thereby improving the response speed.

[0026] In one embodiment, a spring 26 is wound around the outer wall of the copper tube 21, one end of the copper tube 21 is fixedly connected to a limiting plate 27, and both ends of the spring 26 are respectively fixedly connected to the coil 23 and one end adjacent to the limiting plate 27; due to the arrangement of the spring 26, the copper tube 21 pulls the spring 26 after moving, and the counter-pulling force of the spring 26 pulls the copper tube 21 to reset the position of the copper tube 21.

[0027] In one embodiment, a single chip microcomputer 12 is installed outside the gun body 11 , and the single chip microcomputer 12 is electrically connected to the PLB board 29 ; through the setting of the single chip microcomputer 12 , the single chip microcomputer 12 controls the voltage of the coil 23 , thereby changing the vibration frequency.

[0028] In one embodiment, the PLB board 29 is electrically connected to the coil 23; by providing the PLB board 29, the turning on and off of the coil 23 are controlled.

[0029] In one embodiment, a retaining piece 24 is fixedly connected to one end of the coil 23, a bolt 25 is fixedly connected to one end of the copper tube 21, and one end of the bolt 25 penetrates through the retaining piece 24; by providing the bolt 25, the bolt 25 slides in the retaining piece 24 to limit the movement of the copper tube 21.

[0030] When the present utility model is in operation: the voltage of the coil 23 is controlled by the single-chip microcomputer 12, the PLB board 29 activates the coil 23. The four coils 23 are arranged in an alternating manner by forward and reverse winding. After being energized, the current flows in opposite directions, so that the electromagnetic pole directions generated by two adjacent coils 23 are opposite, and interact with the permanent magnet 22 in the copper tube 21 to generate multiple segments of thrust. The permanent magnet 22 drives the copper tube 21 to move, pushing the bolt 25 to move quickly. The bolt 25 slides in the retaining piece 24 to limit the movement of the copper tube 21. The movement of the copper tube 21 generates thrust, imitating the recoil force designed for the gun body 1. At the same time, the Hall sensor 28 detects the permanent magnet 22 moving in the copper tube 21, detects the number of movements of the permanent magnet 22, and thus reads the number of shootings of the gun body 1.

[0031] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
