The eyepiece module is located at one end of the housing assembly and is positioned close to the human eye during use. The objective lens module is positioned away from the human head to acquire images during use. The display module is electrically connected to the control module.

[0007] A connecting mechanism connects the housing assembly and the head-wearing mechanism, allowing the eye observation device to hover over the human eye and the eyepiece module to face the human eye.

[0008] The head-mounted camera mechanism is adjustable in pitch angle and / or horizontal orientation to the head-wearing mechanism, and the head-mounted camera mechanism is connected to the control module by cable or wireless communication.

[0009] The objective lens module acquires a first image, the head camera module acquires a second image, and the display module is configured by the control module to display the first image and / or the second image. When the first image and the second image are displayed together, they are arranged side by side.

[0011] Furthermore, the head-wearing mechanism is a helmet, a hat body, or a simple headgear.

[0012] Furthermore, the simplified headgear includes a forehead support, a head circumference, and a top head support. One end of the head circumference is connected to one side of the forehead support, and the other end of the head circumference is connected to the other side of the forehead support. The top head support connects the forehead support and the head circumference. The head circumference has a first length adjustment structure, making the inner diameter of the ring formed by the head circumference and the forehead support adjustable. The top head support has a second length adjustment structure.

[0013] Furthermore, the head-mounted camera mechanism includes a base and a camera. The base is connected to the head-wearing mechanism, the base is hinged to the camera, and the base is detachably connected to the head-wearing mechanism and its horizontal orientation can be changed.

[0014] Furthermore, the connecting mechanism has a pitch adjustment mechanism, which includes at least one hinge to allow the eye observation device to change its elevation angle.

[0015] Furthermore, the head-wearing mechanism is provided with a first magnetic attraction component, and the end of the connecting mechanism away from the head-wearing mechanism or the housing assembly is provided with a second magnetic attraction component.

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a head-mounted observation device, in conjunction with the accompanying drawings and embodiments, is provided. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0047] Please refer to Figures 1-9 A head-mounted observation device, comprising:

[0048] A head-wearing mechanism 100 is used to be worn on the human head;

[0049] An eye observation device 200 includes a housing assembly 210, an eyepiece module 220, an objective lens module 230, a display module 240, and a control module 250. The eyepiece module 220, objective lens module 230, display module 240, and control module 250 are mounted on the housing assembly 210. The eyepiece module 220 is located at one end of the housing assembly 210 and is positioned close to the human eye during use. The objective lens module 230 is positioned away from the human head to acquire images during use. The display module 240 is electrically connected to the control module 250.

[0050] The connecting mechanism 300 connects the housing assembly 210 and the head-wearing mechanism 100, so that the eye observation device 200 is suspended above the human eye and the eyepiece module 220 is facing the human eye.

[0051] The head-mounted camera mechanism 400 is adjustable in pitch angle and / or horizontal orientation to the head-mounted wearing mechanism 100. The head-mounted camera mechanism 400 is connected to the control module 250 via cable 421 or wireless communication.

[0052] The objective lens module 230 acquires the first image 233, the head camera mechanism 400 acquires the second image 430, and the display module 240 is configured by the control module 250 to display the first image 233 and / or the second image 430. When the first image 233 and the second image 430 are displayed together, they are arranged side by side.

[0053] The eye observation device 200 acquires a first image 233, and the head camera mechanism 400 acquires a second image 430. The eye observation device 200 captures the image directly in front, while the head camera mechanism 400 can be configured at the top, side, front, or rear of the head-mounted device 100, and its angle is adjustable, allowing for a wider frontal view or images from other directions, thus increasing the amount of information that can be acquired. The control module 250 allows the display module 240 to display the first image 233 alone, the second image 430 alone, or both simultaneously. This enables users to acquire wide-field-of-view or multi-directional images in complex environments.

[0054] Preferably, the head-mounted camera mechanism 400 is connected in an adjustable angle via a reusable adhesive, a guide rail slider mechanism, or a magnetic attraction mechanism. Simply put, the reusable adhesive can use Velcro, which allows for easier adjustment of the pitch and horizontal orientation. For example, a first Velcro is provided at the top of the head-mounted mechanism 100, and a second Velcro is provided at the bottom of the head-mounted camera mechanism 400. Typically, the top of the head-mounted mechanism 100 is arc-shaped, and the length of the first Velcro along the front-to-back direction is greater than the length of the second Velcro, thus allowing the head-mounted camera mechanism 400 to adjust its pitch angle. Specifically, the top of the head-mounted mechanism 100 has a platform, with the front and back sides of the platform being sloped or arc-shaped. When the head-mounted camera mechanism 400 is placed on the platform, it shoots horizontally; when the head-mounted camera mechanism 400 is attached to the front and back slopes or arc-shaped surfaces, it tilts at an angle.

[0055] Please refer to Figures 1-3 The head-wearing mechanism 100 is a helmet, cap, or simple headgear.

[0056] Please refer to Figure 1 and Figure 2 The simple headgear includes a forehead support 110, a head circumference 120, and a top head support 130. One end of the head circumference 120 is connected to one side of the forehead support 110, and the other end of the head circumference 120 is connected to the other side of the forehead support 110. The top head support 130 connects the forehead support 110 and the head circumference 120. The forehead support 110 is typically made of high-strength materials such as leather, plastic, metal, or alloy. To protect the forehead, a protective pad 111 can be attached to the side of the forehead support 110 facing the head. The protective pad 111 is made of flexible materials such as silicone, rubber, foam, or leather. The head circumference 120 is typically made of flexible materials such as fabric. To facilitate the connection between the head circumference 120 and the top head support 130, a high-strength connector, such as leather, can be installed on the part of the head circumference 120 corresponding to the back of the head. The top head support 130 can be made of rigid or flexible materials as needed. When a platform is required, a rigid material is typically used, or a combination of rigid and flexible materials can be used, i.e., a rigid platform can be fixedly connected to a soft material. Simply, a platform can be glued or sewn onto fabric. The top head support 130 can be strip-shaped, i.e., one end connects to the forehead support 110 and the other end connects to the head circumference 120, or it can be cross-shaped.

[0057] Please refer to Figure 1 and Figure 2The head circumference 120 has a first length adjustment structure 121, making the inner diameter of the ring formed by the head circumference 120 and the forehead support 110 adjustable; the top head support 130 has a second length adjustment structure 131. Simply put, the forehead support 110 has perforations at both ends, and the head circumference 120 has two Velcro straps on the same side and spaced apart at both ends for length adjustment. Alternatively, the head circumference 120 has two sections, and the length of the two sections can be adjusted by tying ropes, Velcro, adjusting buckles, adjusting holes, etc. When the head support 130 is strip-shaped, it is fixedly connected to the head circumference 120 and adjustablely connected to the forehead support 110. The length can be adjusted simply by using Velcro, adjusting buckles, or adjusting holes. When the head support 130 is cross-shaped, a connecting ring can be set on the platform. The soft part connected to the platform passes through the connecting ring and is adjusted by Velcro. Similarly, the soft part connected to the forehead support 110 can also have a connecting ring set on the forehead support 110. The soft part passes through the connecting ring and is adjusted by Velcro.

[0058] Please refer to Figures 1-3 and Figure 8 The head-mounted camera mechanism 400 includes a base 410 and a camera 420. The base 410 is connected to the head-wearing mechanism 100 and is hinged to the camera 420. The base 410 and the head-wearing mechanism 100 are detachably connected and their horizontal orientation is changeable. Preferably, the base 410 and the camera 420 have a hinge locking mechanism; or, the base 410 and the camera 420 are connected by a damped hinge; or, the base 410 and the camera 420 have a positioning mechanism. Simply put, the positioning mechanism consists of a positioning groove and a positioning protrusion. Generally, there are multiple positioning grooves, and the positioning protrusion moves from one positioning groove to another during rotation. It can be understood that one of the positioning grooves and the positioning protrusions is located on the base 410 and the other is located on the camera 420. The tilt angle can be adjusted, and even the camera can be flipped forward or backward, through the hinge between the base 410 and the camera 420. The tilt angle adjustment is more convenient and precise. The pitch can be adjusted via the hinge between the base 410 and the camera 420, and the orientation can be adjusted via the detachable connection between the base 410 and the head-wearing mechanism 100. The base 410 and the head-wearing mechanism 100 can be connected in various ways, such as snap-fit ​​or threaded connections. For easy horizontal adjustment, the snaps can be arranged symmetrically or in a circular array. Alternatively, Velcro 460 can be attached to the bottom of the base 410. The base 410 can be directly connected to the camera housing 470 of the camera 420, or a hinge bracket 411 can be fixed to the base 410 and hinged to the camera housing 470.

[0059] Please refer to Figures 1-4The connecting mechanism 300 includes a pitch adjustment mechanism 310, which includes at least one hinge 311 to change the pitch angle of the eye observation device 200. The pitch adjustment mechanism 310 allows for adjustment of the pitch angle and also enables the device to be tilted upwards when not in use, facilitating direct observation through the human eye. Specifically, the pitch adjustment mechanism 310 includes a primary hinge 312 and a secondary hinge 313, thus allowing adjustment not only of the pitch but also of the distance between the eye observation device 200 and the human head.

[0060] Please refer to Figures 1-4 The head-wearing mechanism 100 is equipped with a first magnetic element 112, and the connecting mechanism 300, at the end away from the head-wearing mechanism 100 or on the housing assembly 210, is equipped with a second magnetic element 330. When the eye observation device 200 approaches the head-wearing mechanism 100 via the tilt adjustment mechanism 310, the first magnetic element 112 and the second magnetic element 330 magnetically engage. That is, when the eye observation device 200 needs to be tilted up, it maintains stability through magnetic attraction, preventing sudden drops that could cause eye injury. Simply put, one of the first magnetic element 112 and the second magnetic element 330 is a magnet, and the other is a magnet or a ferromagnetic material.

[0061] Please refer to Figures 1-4 The connecting mechanism 300 also includes a distance adjustment mechanism 320, which includes an adjustment guide rail 321, an adjustment slider 322, and a locking member 323. One of the adjustment slider 322 and the adjustment guide rail 321 is connected to the eye observation device 200, and the locking member 323 locks the relative position of the adjustment guide rail 321 and the adjustment slider 322. The distance adjustment mechanism 320 facilitates control of the distance between the eye observation device 200 and the human eye, improving comfort. Specifically, the second magnetic attractor 330 serves as the locking member 323 of the distance adjustment mechanism 320; that is, the locking member 323 is made of a magnet or ferromagnetic material, and the length of the first magnetic attractor 112 is greater than or equal to the stroke of the locking member 323.

[0062] Please refer to Figure 6 and Figure 9The display module 240 has a first display area 241 and a second display area 242 arranged side by side. When the first image 233 is displayed independently, both the first display area 241 and the second display area 242 display the first image 233. When the second image 430 is displayed independently, both the first display area 241 and the second display area 242 display the second image 430. When the first image 233 and the second image 430 are displayed simultaneously, the first display area 241 displays the first image 233, and the second display area 242 displays the second image 430. Preferably, there is a gap between the first display area 241 and the second display area 242 to avoid visual interference between the first image 233 and the second image 430. It is understood that the first display area 241 and the second display area 242 can be formed by a single screen controlled by software, or they can be formed by two screens, i.e., one screen corresponds to the first display area 241 and the other screen corresponds to the second display area 242.

[0063] Please refer to Figure 5 The eyepiece module 220 includes a first eyepiece 221 and a second eyepiece 222. The housing assembly 210 contains a first observation cavity 261 and a second observation cavity 262, which are isolated from each other. The image displayed in the first display area 241 is emitted from the first eyepiece 221 through the first observation cavity 261, and the image displayed in the second display area 242 is emitted from the second eyepiece 222 through the second observation cavity 262. This isolation of the first and second display areas 241 and 242 results in better observation and avoids image interference. Alternatively, the first and second observation cavities 261 and 262 can be formed by an observation chamber 260, i.e., by creating through holes within the observation chamber 260 to form the first and second observation cavities 261 and 262.

[0064] Please refer to Figure 7The system also includes an eyepiece focusing mechanism 270, which comprises a first focusing mechanism 271 and a second focusing mechanism 272. The first focusing mechanism 271 adjusts the refraction of the first eyepiece 221, and the second focusing mechanism 272 adjusts the refraction of the second eyepiece 222. Preferably, both the first eyepiece 221 and the second eyepiece 222 include a set of movable lenses 223 and a set of fixed lenses 224. The eyepiece focusing mechanism 270 drives the set of movable lenses 223 to move closer to or further away from the set of fixed lenses 224, thereby performing refractive adjustment. Generally, the fixed lens 224 is located at the end closer to the display module 240, and the set of movable lenses 223 is located at the end closer to the eye. Simply put, the eyepiece focusing mechanism 270 can be a linear motion mechanism, or, to improve accuracy, it can be a rotary-to-linear motion mechanism. Specifically, the movable lens 223 is connected to a slider 276. The eyepiece focusing mechanism 270 includes an inner cylinder 273 and an outer cylinder 274. The inner cylinder 273 is provided with a linear guide groove, and the outer cylinder 274 is provided with an arc-shaped guide groove. When the outer cylinder 274 rotates, the inner cylinder 273 remains stationary. The slider 276 passes through the linear guide groove and extends into the arc-shaped guide groove. To facilitate rotation, a rotating cylinder 275 can be provided as needed. The rotating cylinder 275 drives the outer cylinder 274 to rotate.

[0065] Preferably, the head-mounted camera mechanism 400 also includes an angle sensor, and the control module 250 acquires the rotation data from the angle sensor to control the second image 430 to flip. The angle sensor can be a Hall sensor, which senses whether the camera 410 is flipped through a magnetic field. For example, when the camera 410 is shooting forward, the second image 430 is displayed normally; when the camera 410 is shooting backward, the second image 430 is mirror-flipped. Simply put, the Hall sensor includes a Hall element 451 and a Hall magnet 452. The Hall element 451 is fixed inside the camera housing 470, and the Hall magnet 452 is fixed inside the base 410.

[0066] For preferred options, please refer to [the provided text]. Figure 5 The objective lens module 230 includes a camera lens 231 and a supplementary lighting lens 232. The camera lens 231 and supplementary lighting lens 232 acquire images and are connected to the control module 250 via a CMOS sensor. The supplementary lighting lens 232 is typically a low-light lens or an infrared lens, facilitating night vision. Simply put, the camera lens 231 can be equipped with a manual or electric focusing mechanism to adjust its focal length as needed. In particular, the head-mounted camera mechanism 400 may also include a supplementary lighting lens, which can be a low-light lens or an infrared lens as needed, meaning the head-mounted camera mechanism 400 can also perform night vision.

[0067] Specifically, when the first image 233 or the second image 430 is displayed alone, the first display area 241 and the second display area 242 can be cropped by software as needed to form a left-right parallax, thereby achieving a naked-eye 3D effect.

[0068] Understandably, the head-mounted camera mechanism 400 is connected to the control module 250 via cable 421 or wireless communication. Preferably, the cable 421 connection means that a port is provided on the eye observation device 200, and the cable 421 extending from the head-mounted camera mechanism 400 is plugged into the port.

[0069] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0070] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0071] In summary, this utility model provides a head-mounted observation device where an eye-observation device acquires a first image, a head-mounted camera mechanism acquires a second image, and the eye-observation device captures the view directly in front. The head-mounted camera mechanism can be configured at the top, side, front, or rear of the head-mounted device, and its angle is adjustable, allowing for a wider frontal view or views from other directions, thereby increasing the amount of information that can be acquired. The control module allows the display module to display the first image alone, the second image alone, or both images simultaneously. This enables users to acquire wide-field-of-view or multi-directional images in complex environments.

[0072] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
