Simulation training device 10 includes host 100, main frame 200 and bottom bar 300.Host 100 is cuboid, main frame 200 be U-shaped structure, is rotatably coupled by the first rotation axis 400 between host 100 and main frame 200, and host 100 can be It is freely rotated in vertical direction along the first rotation axis 400 in the U-shaped groove of main frame 200.200 lower end of main frame passes through second turn Moving axis 500 and 300 one end of bottom bar are rotatably coupled, and 300 other end of bottom bar is contacted with ground, is used to support whole device.It is main Frame 200 can in the horizontal direction be freely rotated along the second rotation axis 500, since host 100 is connect with main frame 200, so main Machine 100 can also be freely rotated in the horizontal direction.In conclusion by the way that orthogonal first rotation axis 400 and second turn is arranged Moving axis 500, host 100 obtain the comprehensive ability being freely rotated.

Fixed frame 700 is housed, fixed frame 700 is U-shaped structure, fixed frame 700 and master between host 100 and main frame 200 Machine 100 is fixedly connected, and is rotatably coupled with the first rotation axis 400, i.e., fixed frame 700 can be with host 100 along the first rotation axis 400 rotate synchronously.100 inside of host includes the precision equipments (not shown) such as computer control system, sensor, fixed frame 700 mainly play support and protective effect to host 100, and above-mentioned precision equipment is prevented to be damaged.

First rotation axis, 400 both ends are connected separately with movable crank 600, and direction is perpendicular to the first rotation axis 400, training When, movable crank 600 can be used to control the rotation direction of host 100, operated more convenient.Movable crank 600 can be with Dismounting, facilitates the transport of simulation training device 10.

One end of host 100 is equipped with form 110, form 110 be include two panels convex lens 111, embedded 100 surface of host, Corresponding with trainee's eyes respectively, the main shaft of convex lens 111 is perpendicular to 100 surface of host.110 top of form is equipped with eyeshade 120,120 middle part of eyeshade is set there are one connecting rod 130, and one end which is equipped with form 110 with host 100 passes through axis pin 140 It is rotatably coupled.Eyeshade 120 is rotated along axis pin 140, eyeshade 120 can be made to be fastened on form 110 or be placed on host 100 Surface.Eyeshade 120 is bitubular shape, and when eyeshade 120 is fastened on form 110,120 one end of eyeshade covers trainee's eyes, The end generally has soft materials, and guarantee is fitted closely with trainee's face, and 120 other end of eyeshade covers form 110.It is trained Personnel can see the image in form 110 by eyeshade 120.Eyeshade 120 can fix the position of trainee's eyes, simultaneously Ambient is sheltered from, ensures observing effect.

It is 100 internal structure schematic diagram of host provided in this embodiment with reference to Fig. 3, Fig. 3.It is set inside 100 other end of host It is equipped with mounting portion 150, mounting portion 150 is used to connect the display equipment 160 of simulated training, refers in the present embodiment specifically It can show the display equipment 160 of 3-dimensional image, certain display equipment 160 can also replace with other and meet setting for training demand It is standby.Show that equipment 160 includes display screen 161, display screen 161 is set as parallel with 100 surface of host where form 110, i.e., The main shaft of convex lens 111 is perpendicular to 161 surface of display screen.Display screen 161 show image, it should by form 110 be it is trained Observed by personnel, so host 100 has hollow structure, that is, the light of a face form 110 and display equipment 160 is provided Channel 170.The light that display equipment 160 is sent out passes through form 110 by light channel 170, eventually enters into human eye.

It shows that equipment 160 is used for showing the 3-dimensional image that computer system simulation goes out, trainee is made to generate stereoscopic vision, from And realistic simulated training environment is built, display equipment 160 must coordinate convex lens 111 to use, and be specifically described as follows：

Why people has stereoscopic vision, and when being object same because of the binocular fixation of people, object is controlling two respectively Retina on be imaged, due to left and right two have spacing, so some fine distinctions of two visual angles, such difference can be led The imaging that two eyes retinas of left and right sprinkle is caused to have a certain difference, the brain visual centre of people is responsible for the two imaging overlappings Get up, become one it is complete, there is relief single object, such function to be known as binocular single vision.

What very important person was conversely speaking, simulates stereoscopic vision, it is necessary to which there will be the images of certain visual angle difference to feed respectively To left eye and right eye, to make one to feel being that object in actual observation image is the same.However, common display equipment 160 There are one display screens 161, and at this moment there are many solutions.For example, time-divided method, computer system is by the figure of left eye and right eye As alternately throwing on display screen 161, and synchronous control signal is sent out, makes the image of 110 synchronism switching images of left and right eyes of form, form Shutter is set on 110, when present image is left-eye image, closes right eye shutter；When present image is eye image, left eye is closed Shutter.Even if left eye only sees the left eye image seen, right eye only sees the right eye image seen.Human eye has the persistence of vision Physiological property, therefore without requiring right and left eyes simultaneously get different images.In another example space split plot design, by display screen 161 are divided into two regions in left and right, and left and right region shows the image of right and left eyes respectively, and the visual field of right and left eyes is isolated, and makes it Can only see itself it should be appreciated that image.After right and left eyes get different images, brain visual centre is stacked up, Form stereoscopic vision.Space split plot design is used in the present embodiment.

But if only stereoscopic vision, also it is not enough to generate the sense of reality of scene, simulation training system is in order to reduce after all The size of volume, display screen 161 is extremely limited, so the 3-dimensional image seen is smaller.Set form 110 to convex lens Mirror 111, main purpose are for magnified image.With reference to Fig. 4, Fig. 4 is the image-forming principle schematic diagram of virtual reality device 1.It is convex In lens imaging principle, object distance (distance of the object to convex lens optical center) u, image distance (convex lens at as arrive convex lens optical center Distance) v, focal length (by the light of convex lens, parallel primary optical axis, convergent point on primary optical axis to convex lens optical center away from From) relationship of f is：1/v+1/u=1/f.And when object distance u and focal length f have different relationships, the imaging mode of convex lens is not yet Together, as shown in the table：

Convex lens image-forming discipline table

As seen from the above table, for magnified image, display screen 161 is set within the focal length f of convex lens 111, at this time will be The rear portion of display screen 161 forms the virtual image of an amplification.Display screen 161 is located in the focal length of convex lens 111, and human eye penetrates convex lens Mirror 111 can see the virtual image of an amplification, and the virtual image is located at the same side of convex lens 111 with display equipment 160.

The amplification factor of convex lens is defined as k=v/u, and k=1/ (u/f-1) can be obtained by above-mentioned two formula, it is seen that adjustment object distance U and focal length f can change amplification factor k.But amplification factor k should be adjusted rationally, if amplification factor k is excessive, due to display The limited resolution of screen 161, institute are serious at virtual image pixel granular sensation；Amplification factor k is too small, the image distance v deficiency distance of distinct vision (photopic visions Distance is exactly eyes most convenient, the operating distance being most accustomed under suitable lighting condition.It is most suitable for normal eye's observation nearby Compared with the distance of wisp, about 25 centimetres.At this moment the regulatory function of human eye is less nervous, can observe for a long time and not easy to fatigue), Then the visual field is narrow, and the scene sense of reality is insufficient.

In addition to the adjustment of object distance u and focal length f, another adjustable parameter is interpupillary distance.Between interpupillary distance, that is, pupil of both eyes away from From the interpupillary distance of adult is usually changeless.When carrying out 3-dimensional image display using space split plot design, pupil is generally required Hole center, 111 optical center of convex lens, display screen 161 (after segmentation) center are on the same line, to obtain optimum visual effect Fruit.The pupil center of obvious people can not adjust, can only adjust lens, in display picture position, but for convenience still This adjustment process is known as interpupillary distance to adjust.Host 100 in the present embodiment, can be to object by the computer system built in it It automatically adjusts away from, parameters such as focal length, interpupillary distance, to meet imaging demand.

According to foregoing description, by the mutual cooperation of convex lens 111 and display equipment 160, trainee has been able to Simulated training environment true to nature is observed in form 110.But this fashion cannot complete simulated training, because trainee still cannot With the environment interaction, it is only limitted to the observation to the environment.Host 100, which has, is freely rotated ability, and biography is also equipped in host 100 Sensor, such as gyroscope can make the rotation behavior of host 100 measurement, and computer system records these measurement data, reconstruct Go out to rotate the three-dimensional motion of behavior, and is fed back to the respective change of picture on display screen 161.That is trainee's operant activity crank When 600 tumbler, it can also change accordingly through the 3-dimensional image observed by form 110, due to simulation training device 10 Rotation be comprehensive, so visual angle change of the trainee in simulated training environment is also full side.Trainee has For the ability with simulated training scene interaction, various simulated training subjects can be effectively completed.Some existing wear-types Virtual reality device will change visual angle, it is necessary to lean on moving-head, time of long duration can cause user tired, provided in this embodiment Virtual reality device 1 carries out visual angle adjustment by operant activity crank 600, the above problem is not present, and its is easy to operate, has More true experience sense.

In conclusion present embodiments providing a kind of virtual reality device 1 for simulated training, it is true to nature to have construction Simulated training environment ability, while it is easy to operate, there is good interactivity, training effect can be improved.

Obviously, above-described embodiment of the utility model is used for the purpose of clearly illustrating the utility model example, and It is not the restriction to the embodiment of the utility model.For those of ordinary skill in the art, in above description On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments It is exhaustive.All any modification, equivalent and improvement made within the spirit and principle of the present invention etc., should be included in Within the protection domain of the utility model claims.
