Description

Technical Field

[0001] The utility model belongs to the technical field of firearm simulation training, in particular to a recoil simulation mechanism. Background Art

[0002] Shooting training is the core process in real firearms training. At the moment of shooting, the gun will instantly produce extremely strong recoil. This recoil vibration itself constitutes an important part of shooting training. With the development of VR technology, for the needs of safety, economy and confrontation, using light weapons simulation training equipment instead of real bullets for shooting training in daily training has become a more convenient and efficient method recognized by the armed police, troops and military enthusiasts. Existing light weapons shooting simulation equipment mostly uses laser simulation guns, compressed gas guns and other methods. For the recoil generated by the firing of real bullets, some simulation systems do not have it. For example, the laser simulation rifle simulates the appearance of the real gun, but it emits weak lasers instead of bullets and does not generate recoil when fired. Some simulation equipment has recoil but the simulation is not strong. Some equipment uses compressed gas to generate recoil, which requires additional equipment to use, and the gas source is inconvenient to replenish, and there is a certain risk. In order to improve the trainees' full perception of the recoil of familiar firearms during training, a recoil simulation device is set in the simulation gun, which has important practical significance for actual training.

[0006] Furthermore, a shaft sleeve is provided at the front end of the main shaft, and the transmission shaft is connected and fixed to the shaft sleeve.

[0007] Furthermore, the transmission shaft is a D-shaped shaft, the shaft sleeve is a D-shaped hole shaft sleeve, and the size of the D-shaped shaft matches that of the D-shaped hole shaft sleeve.

[0008] Furthermore, a set screw is provided at the connection between the transmission shaft and the main shaft.

[0009] Furthermore, the spindle shaft table, the rear plate and the supporting slot plate are an integrated structure.

[0010] Furthermore, a bearing is provided in the circular hole.

[0011] Furthermore, a sleeve is provided at the front end of the main shaft, the thickness of the sleeve is higher than the distance between the outer surface of the spring and the main shaft, and the sleeve is fixed to the main shaft by a set screw.

[0012] Furthermore, the distance between the force-bearing plate and the rear plate can be adjusted.

[0013] Furthermore, the motor is provided with an encoder.

[0014] Furthermore, the cam and the spring are replaceable structures.

[0015] Beneficial effects:

[0016] The utility model discloses a recoil simulation mechanism, which has the characteristics of simple and compact structure, easy to carry and convenient to process; compared with other recoil devices, the recoil simulation mechanism has the advantages of fast firing speed and long firing time, and the recoil simulation mechanism can achieve accurate firing by cooperating with different sensors; the recoil size and impact strength can be adjusted by adjusting the position of the sleeve, which can be suitable for the training needs of different groups of people; after the recoil simulation mechanism is adjusted and set, the recoil simulation consistency is good.

[0017] In view of the fact that existing devices cannot achieve continuous stimulation of recoil in a short period of time or the firing effect is poor, the present invention uses a motor to directly drive the rotating shaft to drive the cam to rotate, and a spring pushes the cam to move and hit the recoil, so that the firing speed is completely the same as the motor output speed, thereby achieving an improvement in the firing speed.

[0018] In the face of the problem of decreased thrust after high-temperature demagnetization in electromagnet-type recoil devices, the firing recoil of this mechanism depends entirely on the spring thrust and the quality of the cam, and has higher stability. At the same time, replacing different springs and cams can produce different recoil forces.

[0019] By adding an encoder to the motor, the number of times the device fires can be precisely controlled. BRIEF DESCRIPTION OF THE DRAWINGS
