[0033] Second, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive of other embodiments.

[0034] Thirdly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, the actual production should include the three-dimensional spatial dimensions of length, width, and depth.

[0035] Embodiment 1 Refer to Figure 1 and Figure 11 、 Figure 12 , which is the first embodiment of the present invention, and provides a multifunctional eyepiece display with a protection device, which includes an eyepiece assembly 100, including an eyepiece base 101 and an eyepiece barrel 102 fixed to one end thereof.

[0036] Among them, Figure 12 is the schematic diagram of the structure of the eyepiece display originally adopted in the design process of the present invention, including an eyecup 1 arranged on the outermost side, a retaining ring 2 arranged inside the eyecup 1 and applying pressure to the solder pad 4 to fix its position, and an insulating seat 3 arranged between the retaining ring 2 and the solder pad 4.

[0037] On the inner side of the eyepiece barrel 8 of the original eyepiece display, there are also arranged an eyepiece first spacer 8, an eyepiece second spacer 7, an eyepiece third spacer 6, and an eyepiece fourth spacer 5 arranged in a gradient manner. The multiple spacers act on the first eyepiece lens 15, the second eyepiece lens 16, the eyepiece cemented lens 17, the fourth eyepiece lens 18, and the fifth eyepiece lens 21, so that the multiple eyepiece lenses are located in independent display spaces and can cooperate with each other.

[0038] Among them, on the outer side of the eyepiece display, there are an OLED connector 10 and an OLED protective cover 11 that cooperate with each other, and an OLED display module 14 at the end face position of the lens. The display is also provided with multiple groups of M2 screws, including the reference numerals 12, 13, and 22 in the schematic diagram. On the outer side of the eyepiece display, there are also an O-ring 19 and a conductive sealing ring 20.

[0039] Based on the further improvement of the original design, the eyepiece barrel 102 is an existing eyepiece structure used inside. The eyepiece barrel 102 and the eyepiece base 101 are detachably fixed, and can be fixed to each other by means of snap connection, locking, or screw tightening. In this embodiment, screw connection is preferably used for fixation. Further, the eyepiece barrel 102 can be fixed to each other by means of segmented screw splicing.

[0040] The protection component 200 includes a protection cylinder 201, a control member 202, and a limiting member 203. The protection cylinder 201 is fixed outside the lens barrel 102. The control member 202 and the limiting member 203 are movably installed on the outer wall of the protection cylinder 201, and the limiting member 203 is fixedly connected to the control member 202.

[0041] Among them, the entire protection component 200 is made of metal or plastic. If cost is not considered, it can also be made of carbon fiber material to ensure the use strength.

[0042] A forehead protection groove 101a is provided at the top of one end of the lens base 101, and a defrosting groove 101b is provided at the bottom of this end of the lens base 101. A relief groove 101c is also provided in the middle of the defrosting groove 101b; the lens barrel 102 is coaxially and fixedly connected to one end of the lens base 101 away from the forehead protection groove 101a.

[0043] Among them, an observation hole is provided in the middle of the lens base 101, which is aligned with the axis of the eyepiece assembly 100, facilitating observation through the eyepiece assembly 100. And preferably, the aperture of the observation hole here is 82 mm to improve the observation experience of the operator. By increasing the eyepiece aperture, the field of view is expanded, enabling a more comprehensive observation of the target area during tactical operations and reducing visual fatigue caused by long-term use.

[0044] Furthermore, during use, when the user observes, the forehead abuts against the forehead protection groove 101a to ensure that the observed image is more stable.

[0045] The defrosting groove 101b can prevent the exhaled breath from directly entering the eyepiece window to form window fog, and then frosting at low temperatures. The relief groove 101c makes way for the nose to prevent the observer's nose from bumping against the eyepiece housing during observation while the vehicle is moving.

[0046] Symmetrically fixed to the outer wall of one end of the lens barrel 102 close to the lens base 101 are fixing plates 102a, and a collar 102b is also fixedly sleeved on the outer wall of the lens barrel 102; the fixing plates 102a are also provided with a first through hole 102a-1 and a second through hole 102a-2. Among them, the fixing plates 102a are preferably long strip-shaped plates symmetrically connected to the outer wall of the lens barrel 102.

[0047] Embodiment 2 Refer to Figures 1 to 6 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the protection cylinder 201 includes a connection seat 201a and main body sleeves 201b and auxiliary sleeves 201c coaxially fixed at both ends thereof. Among them, the main body sleeve 201b is used to protect the main body part of the lens barrel 102, and the auxiliary sleeve 201c is used to protect the lens part of the lens barrel 102.

[0048] One end of the connecting seat 201a close to the main body sleeve 201b is vertically and equidistantly fixed with sliding columns 201a-1. A first spring T1 is sleeved outside the sliding columns 201a-1, and a fixing ring 201a-2 is detachably fixed to the end of the sliding columns 201a-1.

[0049] The sliding columns 201a-1 are slidably inserted into the collar 102b, and both ends of the first spring T1 abut against the connecting seat 201a and the collar 102b respectively.

[0050] During the installation process, the main body sleeve 201b can be first sleeved on the lens part of the lens barrel 102 to ensure that the sliding columns 201a-1 pass through the collar 102b, and then the fixing ring 201a-2 is fixed to the end of the sliding columns 201a-1 by bolts. Finally, the remaining structure of the lens barrel 102 is assembled.

[0051] The outer wall of the main body sleeve 201b is axially fixedly connected with a track block 201b-1. A slideway 201b-1a is formed at the top of the track block 201b-1, and clamping grooves 201b-1b are symmetrically formed on the inner walls of the two opposite sides of the slideway 201b-1a; on the outer wall of one side of the auxiliary sleeve 201c away from the main body sleeve 201b, first hinge blocks 201c-1 are symmetrically and fixedly connected.

[0052] The control member 202 includes a cover 202a and a hinge rod 202b. A second hinge block 202a-1 is fixedly connected to the edge of the cover 202a, and third hinge blocks 202a-2 are symmetrically and fixedly connected to the middle of one side of the cover 202a.

[0053] Among them, the cover 202a can be hermetically covered at the opening end of the auxiliary sleeve 201c.

[0054] The second hinge block 202a-1 is rotatably connected between the first hinge blocks 201c-1. One end of the hinge rod 202b is rotatably inserted between the third hinge blocks 202a-2, and fourth hinge blocks 202b-1 are symmetrically and fixedly connected to the other end of the hinge rod 202b.

[0055] The limiting member 203 includes an upper snap ring 203a and a lower snap ring 203b fixed to the bottom thereof; the upper snap ring 203a includes a first arc plate 203a-1 and first connecting plates 203a-4 fixed to both ends thereof. A sliding block 203a-2 is fixedly connected to the middle of the first arc plate 203a-1, and a pressing member 203a-3 is slidably inserted on the top of the sliding block 203a-2.

[0056] Perforations 203a-4a are formed on the first connecting plates 203a-4. A plurality of groups of limiting columns 203a-4b are symmetrically fixed to the bottom of the first connecting plates 203a-4. The bottom ends of the limiting columns 203a-4b are detachably connected with a bottom plate 203a-4c, and the limiting columns 203a-4b are sleeved with a second spring T2.

[0057] The lower snap ring 203b includes a second arc plate 203b-1 and top plates 203b-2 fixed at both ends thereof. An armrest 203b-3 is also fixed on the outer arc surface of the second arc plate 203b-1. The user can change the overall position of the limiting member 203 by holding the armrest 203b-3.

[0058] A snap block 203b-2a is fixedly connected to the top end of the top plate 203b-2. The limiting post 203a-4b can be slidably inserted into the top plate 203b-2, and the snap block 203b-2a can cooperate to pass through the through hole 203a-4a and be snapped into the first through hole 102a-1 and the second through hole 102a-2.

[0059] Refer to Figure 11 , during use, the protection assembly 200 is in the protection mode. At this time, the snap block 203b-2a is engaged in the first through hole 102a-1, and the cover 202a seals and protects the lens part of the lens barrel 102.

[0060] If it is necessary to switch to the observation mode, at this time, the user only needs to hold the armrest 203b-3 with the hand and pull the lower snap ring 203b downward as a whole. At this time, the second spring T2 is compressed by force, and the snap block 203b-2a is pulled out of the first through hole 102a-1.

[0061] Further, the user pulls the armrest 203b-3 towards himself. The armrest 203b-3 drives the limiting member 203 to slide outside the main body sleeve 201b. The upper snap ring 203a pulls the cover 202a through the hinge rod 202b to open it, and the lens of the lens barrel 102 is exposed until the snap block 203b-2a slides into the second through hole 102a-2 and stops pulling.

[0062] At this time, the user can release the armrest 203b-3 and observe the surrounding environment through the observation hole provided in the middle of the lens holder 101.

[0063] During this process, the main body sleeve 201b will move as a whole with the limiting member 203 for a certain distance, so that the lens of the lens holder 101 moves forward to reach the end opening of the auxiliary sleeve 201c, avoiding the lens being too inward and causing dim light. Further, the moving main body sleeve 20 will compress and store energy in the first spring T1.

[0064] If an emergency occurs and the user needs to take shelter and also needs to ensure the safety of the eyepiece assembly 100, at this time, only need to gently pull the armrest 203b-3, pull out the snap block 203b-2a from the second through hole 102a-2, and then quickly push the armrest 203b-3 forward. At this time, the cover 202a is pushed through the hinge rod 202b to re-block the lens at the end of the main body sleeve 201b.

[0065] During this process, the first spring T1 resets, assisting in pushing the main body sleeve 201b forward to accelerate the speed of switching back to the protection mode. The remaining structures are the same as those in Embodiment 1.

[0066] Embodiment 3 Refer to Figures 1 to 11 , which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that mounting grooves 203a-2a and embedded sliding grooves 203a-2b are respectively provided at the top and bottom of the sliding block 203a-2. A sliding connection block 203a-2b1 is fixed in the middle of the embedded sliding groove 203a-2b. Through holes 203a-2b2 are also provided on both sides of the sliding connection block 203a-2b1 close to the groove wall of the embedded sliding groove 203a-2b.

[0067] One end of the sliding block 203a-2 close to the cover 202a is fixedly connected with a cross bar H. The end of the cross bar H is rotatably inserted between the fourth hinge blocks 202b-1. By the rotational connection between the fourth hinge blocks 202b-1 and the hinge rod 202b, the rotational angle of the cover 202a can be changed.

[0068] At the bottom of the mounting groove 203a-2a, top columns 203a-2a1 are symmetrically and vertically fixed. At the bottom of the mounting groove 203a-2a, horizontal insertion plates 203a-2a2 are also symmetrically and slidably arranged. The horizontal insertion plates 203a-2a2 can cooperate to slide through the through holes 203a-2b2 and be clamped into the card slots 201b-1b.

[0069] During the installation process, after the upper snap ring 203a is installed and fixed on the main body sleeve 201b, the horizontal insertion plates 203a-2a2 are in a state of being horizontally inserted into the through holes 203a-2b2 and the card slots 201b-1b.

[0070] Convex plates 203a-2a2a are symmetrically fixed at both ends of the horizontal insertion plates 203a-2a2. The convex plates 203a-2a2a can cooperate to be inserted into the card slots 201b-1b. A third spring T3 is fixed on the side of the convex plate 203a-2a2a away from the card slot 201b-1b. The other end of the third spring T3 is fixed to the vertical plates 203a-2a3 symmetrically fixed at the bottom of the mounting groove 203a-2a.

[0071] In the initial state, the third spring T3 pushes the horizontal insertion plates 203a-2a2 to extend out of the through holes 203a-2b2 on both sides. At this time, the convex plates 203a-2a2a are completely outside the sliding block 203a-2.

[0072] An inclined push groove 203a-2a2b is provided at the top of the horizontal insertion plate 203a-2a2. Fitting grooves 203a-2a2c are also symmetrically provided on the side wall of the horizontal insertion plate 203a-2a2 away from the convex plate 203a-2a2a. The top columns 203a-2a1 can be placed in the fitting grooves 203a-2a2c in a matching manner.

[0073] The pressing member 203a-3 includes a top sealing plate 203a-3a and an inserting block 203a-3b fixedly connected to the bottom thereof. On both sides of the bottom of the inserting block 203a-3b, there are symmetrically fixedly connected with pushing-back plates 203a-3c. At the end of the pushing-back plate 203a-3c, there are relatively arranged inclined surfaces X. The pushing-back plate 203a-3c is slidably inserted into the inclined pushing groove 203a-2a2b, and the inclined surface X is slidably abutted against the inner wall of the inclined pushing groove 203a-2a2b.

[0074] At the bottom end of the inserting block 203a-3b, there are symmetrically arranged ejector pin holes 203a-3b1. The ejector pin 203a-2a1 can be fitted and inserted into the ejector pin hole 203a-3b1. Between the ejector pin 203a-2a1 and the inner wall of the ejector pin hole 203a-3b1, there is also fixedly connected with a fourth spring T4. In the initial state, the fourth spring T4 jacks up the pressing member 203a-3 upward. At this time, the inserting block 203a-3b is located at the upper opening of the inclined pushing groove 203a-2a2b.

[0075] When it is necessary to install the limiting member 203, it is necessary to first fix the upper snap ring 203a. At this time, it is necessary to press down the top sealing plate 203a-3a. The inclined surface X of the inserting block 203a-3b is inserted downward along the inclined pushing groove 203a-2a2b, thereby pushing the horizontal inserting plate 203a-2a2 to contract into the sliding block 203a-2b1 and the installation groove 203a-2a. At this time, the third spring T3 contracts.

[0076] Furthermore, align the sliding snap block 203a-2 with the slideway 201b-1a and insert it. After the first arc plate 203a-1 is completely attached to the outer wall of the main body sleeve 201b, release the top sealing and resetting plate 203a-3a. The fourth spring T4 resets to jack up the pressing member 203a-3, and the pushing-back plate 203a-3c moves upward. And the horizontal inserting plate 203a-2a2 is no longer limited by the pushing-back plate 203a-3c, so that the third spring T3 resets to push the horizontal inserting plate 203a-2a2 to extend outward and insert into the through-hole 203a-2b2 and the card slot 201b-1b. At this time, the connection and fixation of the upper snap ring 203a and the main body sleeve 201b are completed.

[0077] Furthermore, when installing the lower snap ring 203b, only need to align the hole position on the top plate 203b-2 with the limiting post 203a-4b, then sleeve the top plate 203b-2 on the limiting post 203a-4b, and then sleeve the second spring T2 outside the limiting post 203a-4b. Finally, fix the bottom plate 203a-4c on the limiting post 203a-4b with a micro bolt, and the overall fixation of the limiting member 203 is completed.

[0078] This solution uses modular connection and fixation to achieve the rapid installation of the entire limiting member 203. Moreover, since the limiting member 203 has no protective measures, it is more likely to be damaged. The modular structure is more convenient for replacing damaged components, improving the reuse rate of components and reducing production costs.

[0079] During use, if this device is not needed, it is in the protection mode. At this time, the cover 202a seals and protects the lens part of the lens barrel 102. The limiting member 203 is located at the front end of the eyepiece assembly 100. At this time, the block 203b-2a is inserted into the first through hole 102a-1, and at the same time, the cross bar H maintains the sealing and protection state of the cover 202a through the hinge rod 202b.

[0080] If this device needs to be switched to the observation mode, at this time, the user needs to pull down the handrail 203b-3. The handrail 203b-3 drives the lower clamping ring 203b to move downward as a whole, and the block 203b-2a disengages from the first through hole 102a-1. Further, the user pulls the handrail 203b-3 backward, and the block 203b-2a slides along the lower part of the fixed plate 102a.

[0081] During this process, the cross bar H moves synchronously with the lower clamping ring 203b, pulls the hinge rod 202b backward, and the hinge rod 202b drives the cover 202a to rotate and open, and the lens barrel of the eyepiece assembly 100 opens.

[0082] Further, when the block 203b-2a slides to the corresponding position of the second through hole 102a-2, the user releases the handrail 203b-3. The second spring T2 pushes up the lower clamping ring 203b, so that the block 203b-2a is inserted into the second through hole 102a-2. At this time, the entire limiting member 203 is fixed and is in the rear end position of the eyepiece assembly 100, and the user can observe the surrounding environment through the lens base 101.

[0083] The remaining structure is the same as that of Embodiment 2.

[0084] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
