As seen in fig. 1, 2, 3, 4; it is obvious that in embodiments 1, 2 and 3, the direct view normal of any one of the user's eyes is not blocked, so that the user can determine the observation of the image display device by subjective awareness, and the parallax of bright and dark can be reduced because the

image display devices

Referring to fig. 5, an embodiment of the connecting member 101 of the helmet and the image display apparatus 102 applied in example 1 is described, in which the connecting member 101 includes a first connecting portion 501, a second connecting portion 503, and a connecting arm 502 connecting the first connecting portion 501 and the second connecting portion 503, wherein the first connecting portion 501 of the connecting member 101 is mounted on the helmet and can be fixed to the helmet by screws or the like; in addition, a pluggable structure may be adopted, and when the pluggable structure is adopted, when the image capturing device and the power supply are not located in the image display device 102, an electrical interface connected to the image display device 102 may be provided. The connecting arm 502 is movably connected to the first connecting portion 501 and the second connecting portion 503, for example, by a rotatable damping rotating shaft, and obviously, the image display device 102 is disposed on the second connecting portion 503, for example, up and down adjustment can be performed according to the rotating direction of the rotating shaft, and the rotated position can be stabilized after the angle adjustment, and further, the second connecting portion 503 includes a rotating mechanism, which is connected to the connecting arm 502 by the rotatable damping rotating shaft, and obviously, the rotated position can be stably adjusted according to the rotating direction of the rotating shaft, for example, up and down adjustment can be performed after the angle adjustment. A first guide rail 5031 is provided at the lower end of the rotating mechanism, the image display device 102 can move in the X-axis direction if it is disposed on the first guide rail 5031, and when the movement in the Y-axis direction is required, it can be further optimized, for example, by disposing the transition mechanism 504 at the first guide rail 5031, disposing the image display device 102 on the first slide rail 5041 at the transition mechanism 504, and disposing the image display device 102 on the first slide rail 5041, so as to achieve the movement in the Y-axis direction of the image display device 102, it is obvious that the XY-axis movement of the image display device 102 on the same plane can be achieved through the first guide rail 5031 of the rotating mechanism and the first slide rail 5041 of the transition mechanism, the image display device 102 and the second connecting portion 503 are connected by a fixing member 505, and the preferable mode of the fixing member 505 is through a universal adjusting structure (e.g. a universal ball), when the second connecting portion 503 includes the rotating mechanism 5031, or the transition mechanism 504, or both, the attachment may also be made using the fastener 505 and its associated mechanism. The structure of the connecting member 101 can obviously realize adjustment of at least one of relative positions or angles of the image display device 102 and human eyes, such as up and down, left and right, distance, and included angle between the image display device 102 and human eyes, so that a user can obtain a comfortable observation effect.

The above-described structure can also be adopted for the connection member 201 of embodiment 2; alternatively, the connector 101 (or also the connector 201, 301) may be formed from a flexible shaped member such as a serpentine tube, or as some of these, a serpentine tube may be used to perform one or both of the adjustment functions. For example, all or part of the connecting arm may be replaced by a flexible modular member, although the turning mechanism or transition mechanism 504 may be replaced by a flexible modular member to perform some or all of the functions. The angle between the display device and the eyes of a helmet wearer, the vertical direction, the left-right direction and the distance, and the angle between the sight line of the eyes of a user and the display device can be conveniently adjusted, so that the image display device can be arranged outside the normal line of the front view of the eyes.

Referring to fig. 10, an embodiment of the connection 201 of the helmet and the image display device 102 suitable for use in example 2 is described, wherein the connection 201 comprises a first connection portion 1001, a second connection portion 1003, and a connection arm 1004, the connection arm 1004 is a flexible and fixed member, generally a serpentine tube, with a length of the serpentine tube generally being 10cm-30cm, wherein the first connection portion 1001 and the second connection portion 1003 are pluggable electrical interfaces (such as electrical plugs), and meanwhile, the image display device 102 and the helmet are respectively provided with corresponding electrical interfaces (such as electrical sockets matched with the electrical plugs), and the electrical connection wires of the image acquisition device and the image display device 102 are wrapped in the serpentine tube, and in use, the first connection portion 1001 of the connection 201 is inserted into the electrical interface of the helmet, and then the second connection portion 1003 is inserted into the electrical interface of the image display device 102, the position of the image display device 102 is adjusted according to different operators, so that the purpose of observing without obstructing the sight line can be realized. In this example, the first connecting portion 1001, the second connecting portion 1003 and the connecting arm 1004 may be designed integrally, i.e. both ends of the connecting arm 1004 are designed directly as electrical interfaces. Of course, as a modification, one of the first connecting portion 1001 or the second connecting portion 1003 is designed as an electrical interface, and the other connecting portion is fixedly connected to the helmet or the image display device 102. The advantage of the above design is that the structure is simple, the coiled pipe can wrap various communication and power connection lines, and the adjustment is universal, and in addition, if the first connecting part 1001 and the second connecting part 1003 adopt a universal electrical interface, such as a pluggable electrical interface, the helmet or the image display device 102 can be respectively configured according to different requirements, thereby realizing modular assembly. The pluggable electrical interface may be, for example, a 4-pin thunderstorm (LEMO) connector (for example, lm.sg767, FGG 0B305, including a plug and a socket) according to the power and video signal requirements.

In order to ensure the comfort of human eyes, the walking of a user is not influenced; the image display device 102 described above may be arranged within a predetermined distance (e.g., within 15cm of the distance between the eye and the image display device) without normal occlusion to the emmetropia of the human eye (i.e., the direct-view state in which the pupil is located in the middle of the eye), and a liquid crystal display (e.g., 2-5 inches) of a certain size may be preferably used to facilitate observation by both eyes.

If the image display device 102 directly uses a common liquid crystal display screen without adding a lens, the distance for the liquid crystal display screen to be viewed by human eyes is limited, for example, the distance for the human eyes to observe an object is about 15CM away from the human eyes, and the object cannot be seen clearly or is easy to fatigue close to the distance; in order to ensure the comfort of observation, the connector 101 needs to be long, which affects the convenience of use.

An embodiment of the image display device 102 is described with reference to fig. 6. Fig. 6(a) is an external view of the image display device, fig. 6(b) is a schematic view of components of the image display device, and fig. 6(c) is a schematic view of an assembly of the image display device. In fig. 6, like parts are given like numbers; comprises a light shield 601, a lens 602, a first member 603, a second member 604, a display 605 and a rear cover 606;

as shown in fig. 6(b), the second member 604 is provided with a fixing member 6041, and the image display device 102 and the connector 101 can be connected by, for example, bolting.

As shown in fig. 6(c), the light shield 601 and the lens 602 are attached to the first member 603, and are fixed to a rubber ring 6032 or the like by the front portion of the first member 603; the second member 604 is connected to the first member 603 by way of interpolation, and the liquid crystal display 605 is installed in the second member 604, wherein the distance L between the lens 602 and the liquid crystal display 605 can be adjusted by releasing the screw 6031 to adjust the position of the second member 604 in the first member 603, so as to enable different user applications. Obviously, also an embodiment of the distance L parameter can be fixed, and the respective first member 603 and second member 604 can be integral.

The light shield 601 is generally a PC or rubber member, which can prevent strong sunlight from interfering with the image observation of the image display device. Obviously, the light shield 601 may also be omitted. Wherein the first member 603 and the second member 604 can also have a certain shading effect.

The liquid crystal display 605 may be a common TFT liquid crystal display, or a display of STN, OLED, LED, or the like; the lens 602 can be a magnifying glass, and can be made of various materials (for example, plastic is made of materials such as crystal material, glass and the like and curvature to make the lens, and can be a convex lens, a semi-convex lens, a Fresnel lens or other kinds of magnifying glasses, and the function of the lens is mainly two points, firstly, the lens on the LCD liquid crystal display is magnified, and secondly, the problem that images are not clear when human eyes are too close to the liquid crystal display is solved, wherein the display 605 can be parallel to the lens 602, the lens is a magnifying glass, the distance between the display and the lens is within a certain range, when only 1 lens is provided, the distance L between the display 605 and the lens 602 is preferably smaller than or equal to 1 focal length of the lens 602, and when 1 lens is provided, the normal distance between the display 605 and the central point of the group of the lens is smaller than or equal to 1 focal length of the group of the lens.

Preferably, an adjusting mechanism can be disposed between the lens 602 and the first member 603 for adjusting the distance between the lens 602 and the display 605, for example, the lens is fixed at one end of the screw device, the first member 603 is internally provided with a screw thread matching with the screw device, so that the distance between the lens 602 and the display 605 can be adjusted by screwing in or out the screw device, of course, as mentioned above, the lens is fixed at the first member 603, and then the distance between the lens 602 and the display 605 can be adjusted by releasing the screw 6031 to adjust the position between the first member 603 and the second member 604.

Fig. 6(b) is a theoretical cross-sectional view of fig. 6(a), where it can be seen that the display 605 is parallel to the lens 602 at a distance L and the display 605 is at a distance h from the edge of the mask. The surface of the display screen is point A, and the edge of the light shield is point B. Take a Fresnel lens with a 2 inch LCD screen and 3 times magnification as an example. Through experiments, when h is 70mm, when human eyes observe the infrared thermal image on the A point screen at the B point, the image is blurred and is very labored. After a Fresnel lens which is 3 times that of a C point 35mm away from the A point is arranged, when infrared thermal images on a screen of the A point are observed by human eyes at the B point, the images can be perceived to be clear, and the images are effectively amplified, so that the infrared thermal images are more beneficial to observation and do not have a feeling of being labored. Further, the same experiment was performed using the same fresnel lens for both the 1.5 inch screen and the 2.5 inch screen, with the distances of L and h fixed, and similar results were obtained. Wherein, when testing the 2.5 inch screen, the screen size is as follows: 50 × 38mm, magnifier size: 64 × 51mm, mask size: 70 x 56 mm. For the 2 inch screen test, screen size: 40 × 30mm, magnifier size: 50 × 35mm, mask size: 60 x 39 mm. 1.5 inch screen test, screen size: 30 × 23mm, magnifier size: 37 × 25mm, mask size: 40 x 28 mm.

The theoretical basis is based on the basic principle of the magnifier, as shown in fig. 9: the candle in the figure is positioned at the object distance which is less than one time of focal distance, and the absolute value of the image distance is greater than the object distance, so that the candle becomes an enlarged and upright virtual image. Therefore, when the human eyes watch the LCD screen at the image distance point, the virtual image is actually seen after being magnified, and the visual effect of the virtual image is equivalent to that the object is far away from the eyes, so that the virtual image is not blurred and labored.

Wherein the display 605 can be liquid crystal display of various sizes, preferably 1.5 inch to 3.5 inches depending on the application; the size of the glasses is larger than that of the existing monocular or binoculars, and the users can observe the glasses conveniently. The above design of the image display device 102 integrates three features of large display screen display, close-range observation and no interference from sunlight.

The effect of the user wearing the helmet is explained with reference to fig. 7;

wherein, fig. 7 (a), fig. 7 (b) and fig. 7 (c) respectively show the effect of the upper left side, the lower left side and the left side of the user relative to the eyes after wearing; the effects are obvious that the user wears comfortable and is convenient to observe, and the influence on walking is small; the connecting piece in the structure can be fixed or can be pluggable; it may also be adjustable, for example, by forming the connecting member from a flexible shape-defining member such as a coil, or as a part thereof, by bending and shaping the coil to realize the position setting and adjusting functions of the image display device in fig. 7 (a), 7 (b), and 7 (c). The angle between the display device and the eyes of a helmet wearer, the vertical direction, the left-right direction and the distance, and the angle between the sight line of the eyes of a user and the display device can be conveniently adjusted, so that the image display device can be arranged outside the normal line of the front view of the eyes.

A preferred embodiment is described with reference to fig. 7 (d); the connecting member between the image display device 703 and the helmet includes a first connecting portion 705, a second connecting portion, and a connecting arm, as described above, wherein the connecting arm is composed of a rigid member 701 (which is not bendable and is shaped), and a bendable and shaped member 702 (such as a serpentine tube) connected to the rigid member 701; the first connection part 705 is configured to be removable, and the first connection part 705 is configured to be rotatable after being connected to the helmet (after being inserted into the helmet), for example, a (e.g., damping) rotation mechanism may be provided in the interface of the helmet, or a (e.g., damping) rotation mechanism may be provided in the rigid part 701.

An example of the first connection portion in the inserted state of the helmet connection interface is described with reference to fig. 8(a), (b), wherein the helmet interface includes a rotatable component 7042, a base 7041 disposed on the rotatable component 7042, and an electrical socket 7043 located on the base 7041; and a receptacle 7011 and an electrical plug 7012 in the first connecting portion in the inserted state. Wherein the other end of the electrical outlet 7043 is connected to a suitably lengthened wire (not shown) to accommodate wire twisting and deformation under rotation. Wherein a mechanism with damping, such as a gear with damping, can be used between the rotatable component 7042 and the helmet to effect rotation, or a rotation mechanism and a rotational position locking mechanism.

The flexible shaped member 702 (e.g., serpentine tube) coupled to the rigid member 701 allows for any adjustment of bending or the like, and allows for the positioning effect as shown in fig. 7. Because the connecting arm is formed by adopting a part of rigid parts (which can not be bent and shaped) and the bendable and shaped parts, the double effects of convenience and attractiveness in adjustment can be ensured.

Further, it is preferable that the image capturing device (imaging device) is disposed inside the helmet (or in the image display device), and captures image data by external light transmitted through the opening or the optical material (e.g., the lens 706 in fig. 7 d) in the opening of the helmet. In addition, the image acquisition device can also be fixed on the connecting arm in the embodiment.

Taking the thermal imaging device installed in the helmet as an example, the infrared window (the optical material at the opening) can be made of various materials capable of transmitting infrared light, such as an artificial crystal material, preferably, single crystal germanium is used as the window material, the transmittance of the infrared light with the wavelength of 3-5 or 8-14 microns is more than 95%, and further, an anti-reflection film is additionally plated on the window material to enhance the transmittance of the infrared light. The infrared window is mounted to the helmet at the opening by means of an adhesive. Obviously, install image device inside the helmet, can reach following beneficial effect:

1) the helmet is installed inside, and all the parts forming the imaging device can be manufactured into a whole or a plurality of separated parts, so that the helmet is easy to configure and balance loads, and compared with the prior art, the helmet has improved wearing comfort.

2) The helmet is installed inside a helmet, the imaging device is in a helmet internal environment with high protection performance, and the protection performance is much simpler than that of the prior art, so that even the imaging device 1 does not need a protective shell. The weight and cost of the imaging device 100 can be greatly reduced.

3) The imaging device installed inside the helmet can reduce or even eliminate the need for installation and wiring by the user, and the failure rate and damage rate are reduced.

As a variation, the present invention may also be applied without using a helmet, as shown in fig. 11, the portable camera device includes an image capturing device 1103 and an image display device 102, the image capturing device and the image display device 102 are connected by a connecting part 1102, the connecting part 1102 may be a serpentine pipe, the serpentine pipe internally encloses electrical connecting wires of the image capturing device and the image display device 102, such as power lines and communication connecting wires, the structure of the connecting part 1102 may be the same as that of the connecting part 201 in fig. 10, a fixing device 1104 for fixing the image capturing device is provided in the housing of the image capturing device, the fixing device may be a strap, a snap-in structure or a plug-in structure, the fixing device may be tied to the head, shoulders, arms, etc. of the user by the strap, or may be fixed to a helmet provided by a third party by a plug-in structure or a snap-in structure, the user can adjust (adjust up and down, distance, left and right to the eyes, angle to the line of sight, etc.) conveniently through the connection 1102.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and decorations can be made without departing from the spirit of the present invention, and these modifications and decorations should also be regarded as being within the scope of the present invention.
