Abstract
Description
Technical Field
[0001] At least one embodiment of the present invention relates to the field of porthole technology, and more particularly to a marine porthole. Background Technology
[0002] Existing marine portholes are protected by external guardrails or fixed metal mesh structures. However, these methods have many drawbacks. For example, external guardrails not only affect the appearance of the ship but also significantly increase wind resistance, leading to increased energy consumption. Fixed metal mesh obstructs the view in daily life and lacks practicality in non-dangerous scenarios. When faced with attacks from cutting tools, the strength of external guardrails or fixed metal mesh is not high enough to provide effective safety protection. Summary of the Invention
[0003] In view of this, the present invention provides a marine porthole that, by providing a protective part, can provide protection when needed, and does not obstruct the field of vision when protection is not needed.
[0004] An embodiment of the present invention provides a marine porthole, comprising: a shell disposed on the inner side of the ship's wall and forming an accommodating space, wherein the ship's wall has a through hole communicating with the accommodating space; a porthole inner frame disposed on the side of the shell away from the ship's wall, wherein the porthole inner frame is provided with glass matching the shape of the through hole; a protective part disposed within the accommodating space; and a driving part configured to drive the protective part to unfold to block the through hole, or to drive the protective part to retract to one side of the accommodating space to expose the through hole.
[0005] Optionally, the protective part includes: a fixed strip located on one side of the receiving space; a rotating strip rotatably connected to the fixed strip via a first rotating shaft and connected to the driving part; and a linkage assembly connected to the fixed strip and the rotating strip respectively. When the driving part drives the rotating strip to rotate around the first rotating shaft in a first direction, the linkage assembly unfolds to block the through hole; when the driving part drives the rotating strip to rotate around the first rotating shaft in a second direction opposite to the first direction, the linkage assembly retracts to one side of the receiving space to expose the through hole.
[0006] Optionally, the linkage component includes: N unfolding bars, sequentially disposed between the fixed bar and the rotating bar, where N is greater than or equal to 1; and M connecting bars, each connecting bar being used to connect two adjacent unfolding bars, or to connect the fixed bar and an unfolding bar adjacent to the fixed bar, or to connect the rotating bar and an unfolding bar adjacent to the rotating bar, so that when the driving unit drives the rotating bar to rotate around the first axis in a first direction, the rotating bar drives the unfolding bar to rotate around the first axis in the first direction through the connecting bars; when the driving unit drives the rotating bar to rotate around the first axis in a second direction, the rotating bar pushes the unfolding bar to rotate around the first axis in the second direction through the connecting bars, where M is greater than N.
[0007] Optionally, the first end of each connecting bar is rotatably connected to one of the two adjacent unfolding bars, or rotatably connected to one of the fixed bar and the unfolding bar adjacent to the fixed bar, or rotatably connected to one of the rotating bar and the unfolding bar adjacent to the rotating bar; the second end of each connecting bar is slidably connected to the other of the two adjacent unfolding bars, or slidably connected to the fixed bar and the other of the unfolding bar adjacent to the fixed bar, or slidably connected to the rotating bar and the other of the unfolding bar adjacent to the rotating bar, so that when the linkage assembly is retracted, the connecting bar slides to be received in the other of the two adjacent unfolding bars, or received in the fixed bar and the other of the unfolding bar adjacent to the fixed bar, or received in the rotating bar and the other of the unfolding bar adjacent to the rotating bar.
[0008] Optionally, one of the two adjacent unfolding bars, the fixed bar and the other unfolding bar adjacent to the fixed bar, and the rotating bar and the other unfolding bar adjacent to the rotating bar form a receiving groove for accommodating the connecting bar.
[0009] Optionally, an arc-shaped limiting groove is formed in the accommodating space, and a sliding member matching the shape of the limiting groove is provided on the side of the unfolding bar and the rotating bar away from the first rotating axis. The unfolding bar and the rotating bar rotate around the first rotating axis based on the cooperation of the limiting groove and the sliding member.
[0010] Optionally, the rotating bar has a strip-shaped hole, and an extension plate is formed within the receiving space. The extension plate has a guide groove. The driving part includes: a driving assembly; a moving member movably connected to the driving assembly; and a driving rod movably disposed on the moving member. The driving rod passes through the guide groove and is connected to the strip-shaped hole so that when the driving assembly drives the moving member to move along the driving assembly, the driving rod moves along the guide groove, thereby driving the rotating bar to rotate around the first rotating axis based on the cooperation of the strip-shaped hole and the driving rod.
[0011] Optionally, the extension plate also forms a groove communicating with the guide groove, and a locking hole is formed on the side of the guide groove opposite to the groove. The marine porthole also includes: an elastic component extending from the groove through the guide groove to the locking hole; an unlocking component disposed on the moving component, and the extension plate also forms a locking groove matching the shape of the unlocking component; wherein, during the process of the drive rod moving from the first end of the guide groove to the second end of the guide groove, the drive rod pushes the elastic component to move into the groove; when the drive rod moves to the second end of the guide groove, the unlocking component and the locking groove prevent the drive rod from moving to the first end of the guide groove; during the process of the drive rod moving from the second end of the guide groove to the first end of the guide groove, the unlocking component pushes the elastic component to move into the groove.
[0012] Optionally, the elastic component includes: an elastic element disposed in the groove; a locking element, the first end of which is connected to the elastic element, and the second end of the locking element passing through the guide groove and disposed in the locking hole; wherein, a first slope is formed on the first side of the second end of the locking element, and a second slope is formed on the second side of the second end of the locking element; during the process of the driving rod moving from the first end of the guide groove to the second end of the guide groove, the driving rod abuts against the first slope; during the process of the driving rod moving from the second end of the guide groove to the first end of the guide groove, the unlocking element abuts against the second slope.
[0013] Optionally, when the protective part is deployed to block the through hole, the angle formed by each connecting strip and the fixing strip towards the first direction is an obtuse angle.
[0014] According to embodiments of the present invention, by placing the protective section inside the hull rather than outside the hull, the streamlined design of the ship can be maintained, preserving the overall aesthetic appearance, without increasing wind resistance, and reducing problems such as seawater corrosion and ultraviolet aging, thus extending the service life of the protective section. By providing a drive unit, the protective section can have both a retracted and an extended state. When protection is needed, the protective section can be extended to block the through-hole, providing protection; when protection is not needed, the protective section can be retracted to the side of the accommodating space, exposing the through-hole, thereby not obstructing the field of vision.

Detailed Implementation
[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0031] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

Similarly, when using expressions such as "at least one of A, B, or C," the expression should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art. For example, "a system having at least one of A, B, or C" should include, but is not limited to, systems having A alone, having B alone, having C alone, having A and B, having A and C, having B and C, and / or systems having A, B, and C.
[0034] It should also be noted that the directional terms mentioned in the embodiments, such as "up," "down," "front," "back," "left," and "right," are only for reference to the directions in the accompanying drawings and are not intended to limit the scope of protection of the present invention. Throughout the accompanying drawings, the same elements are represented by the same or similar reference numerals. Conventional structures or constructions will be omitted where they may cause confusion in understanding the present invention.
[0035] Figure 1 A diagram showing the positional relationship between a marine porthole and the ship's bulkhead according to an embodiment of the present invention is provided. Figure 2 It shows Figure 1 The illustrated embodiment is shown in a cross-sectional view cut perpendicular to the housing direction. Figure 3 It shows Figure 1 The illustrated embodiment is shown in a cross-sectional view cut parallel to the direction of the housing. Figure 4 It shows Figure 1 The illustrated embodiment is a cross-sectional view taken at another angle, parallel to the direction of the housing. Figure 5 A perspective view of a marine porthole according to an embodiment of the present invention is shown, wherein the glass is not shown. Figure 6 It shows Figure 5 A cross-sectional view of the embodiment shown.
[0036] like Figures 1-6As shown, the present invention provides a marine porthole. The marine porthole may include a housing 1, a porthole inner frame 3, a protective part 4, and a drive part 5. The housing 1 may be located inside the ship's bulkhead 2, i.e., within the cabin. The housing 1 may form an accommodating space 11. The housing 1 may be constructed in a fan-shaped, circular, or square structure, and form an accommodating space 11 in such a shape. The ship's bulkhead 2 may have a through hole 21 communicating with the accommodating space 11. The porthole inner frame 3 is located on the side of the housing 1 away from the ship's bulkhead 2 (e.g., ...). Figure 2 (The left side of the hull 1 shown). A glass 31 matching the shape of the through-hole 21 is provided on the inner frame 3 of the porthole, allowing observation of the external situation from inside the cabin through the glass 31 and the through-hole 21. The orthographic projection of the accommodating space 11 can be larger than the orthographic projection of the through-hole 21. The orthographic projection can be represented as the projection in a direction perpendicular to the hull 1. The glass 31 can be explosion-proof glass. The explosion-proof glass can be made of 8mm polycarbonate material. A porthole outer frame 8 can be installed inside the through-hole 21. The porthole outer frame 8 can be made of stainless steel. The porthole outer frame 8, the inner frame 3 of the porthole, and the hull 1 can be integrally formed.
[0037] Furthermore, the protective part 4 can be disposed within the receiving space 11. The driving part 5 can also be disposed within the receiving space 11. The driving part 5 can be used to drive the protective part 4 to unfold and block the through hole 21. The driving part 5 can also be used to drive the protective part 4 to retract to one side of the receiving space 11 to expose the through hole 21. That is, when the protective part 4 is in the unfolded state, the protective part 4 can block the through hole 21 to provide protection. When the protective part 4 is in the retracted state, the protective part 4 does not block the through hole 21, thus not affecting the field of view.
[0038] According to an embodiment of the present invention, by placing the protective part 4 on the inner side of the ship's wall 2 rather than on the outer side, the streamlined design of the ship can be maintained, the overall aesthetic appearance can be preserved, the wind resistance during navigation can be reduced, and problems such as seawater corrosion and ultraviolet aging can be reduced, thus extending the service life of the protective part 4. By providing the driving part 5, the protective part 4 can have a retracted state and an extended state. When protection is needed, the protective part 4 can be extended to block the through hole 21 to provide protection. When protection is not needed, the protective part 4 can be retracted to one side of the receiving space 11, exposing the through hole 21, thereby not affecting the field of view.
[0039] like Figures 1-2As shown, in some embodiments, a cover plate 32 and a mounting bracket 33 may also be provided on the inner frame 3 of the porthole. The glass 31 can be mounted to the inner frame 3 of the porthole via the mounting bracket 33. The mounting bracket 33 and the cover plate 32 can be rotatably connected to the inner frame 3 of the porthole, for example, by bolts. The mounting bracket 33 can be located between the cover plate 32 and the inner frame 3 of the porthole. By rotating the mounting bracket 33 and the cover plate 32, the protective part 4 can be exposed, thereby facilitating maintenance or repair of the protective part 4. By rotating the cover plate 32, the glass 31 can be covered, thereby protecting the glass 31 when observation is not required.
[0040] like Figures 1-6 As shown, in some embodiments, the protective part 4 may include a fixing strip 41, a rotating strip 42, and a linkage assembly 43. When the protective part 4 unfolds into a fan shape or a circle, the fixing strip 41 and the rotating strip 42 may extend radially along the fan shape or the circle, respectively. The fixing strip 41 is located on one side of the receiving space 11 (e.g., Figure 3 The left side of the middle and Figure 4 (Right side of the image). The rotating bar 42 is rotatably connected to the fixed bar 41 via the first rotating shaft 46. The rotating bar 42 is also connected to the drive unit 5. The drive unit 5 can drive the rotating bar 42 to rotate around the first rotating shaft 46. The linkage assembly 43 can be connected to both the fixed bar 41 and the rotating bar 42. The linkage assembly 43 can have a retracted state and an extended state. The drive unit 5 drives the rotating bar 42 to rotate around the first rotating shaft 46 in a first direction (e.g., the right side of the image). Figure 3 clockwise direction and Figure 4 When the rotating bar 42 rotates counterclockwise (in the first direction), it drives the linkage assembly 43 to rotate around the first axis 46 in the first direction, thereby unfolding the linkage assembly 43 to block the through hole 21. When the driving unit 5 drives the rotating bar 42 to rotate around the first axis 46 in the second direction opposite to the first direction (e.g., counterclockwise), the linkage assembly 43 will unfold to block the through hole 21. Figure 3 The counterclockwise direction shown and Figure 4 When the rotating bar 42 rotates clockwise, it drives the linkage component 43 to rotate around the first axis 46 in the second direction, thereby causing the linkage component 43 to retract to one side of the receiving space 11 to expose the through hole 21. The first direction can be represented as the unfolding direction, and the second direction can be represented as the retracting direction.
[0041] like Figures 1-6As shown, in some embodiments, the linkage assembly 43 may include N unfolding bars 44 and M connecting bars 45. N may be greater than or equal to 1. M may be greater than N. N and M are positive integers. When the protective part 4 unfolds into a fan shape or a circle, the unfolding bars 44 may extend in the radial direction of the fan shape or circle. The unfolding bars 44, connecting bars 45, fixing bars 41, and rotating bars 42 may be made of shear-resistant materials to have strong impact resistance; for example, the unfolding bars 44, connecting bars 45, fixing bars 41, and rotating bars 42 may be made of titanium alloy. The end of the unfolding bar 44 near the first pivot 46 is configured to gradually narrow so that the protective part 4 has a small volume when it is closed.
[0042] like Figures 1-6 As shown, N unfolding bars 44 can be sequentially arranged between the fixed bar 41 and the rotating bar 42. Each connecting bar 45 can be used to connect two adjacent unfolding bars 44, or to connect the fixed bar 41 and the unfolding bar 44 adjacent to the fixed bar 41, or to connect the rotating bar 42 and the unfolding bar 44 adjacent to the rotating bar 42.
[0043] Figure 7 A perspective view of the protective part according to an embodiment of the present invention is shown.
[0044] Furthermore, such as Figures 1-7 As shown, the connecting strip 45 may include a first connecting strip 45a, a second connecting strip 45b, and a third connecting strip 45c. The first connecting strip 45a can be used to connect two adjacent unfolding strips 44. The second connecting strip 45b can be used to connect a fixed strip 41 and an adjacent unfolding strip 44. The third connecting strip 45c can be used to connect a rotating strip 42 and an adjacent unfolding strip 44. Multiple first connecting strips 45a can be provided between two adjacent unfolding strips 44. Multiple second connecting strips 45b can be provided between the fixed strip 41 and the adjacent unfolding strip 44. Multiple third connecting strips 45c can be provided between the rotating strip 42 and the adjacent unfolding strip 44.
[0045] The drive unit 5 drives the rotating bar 42 to rotate around the first rotating shaft 46 in a first direction (e.g.) Figure 4 When the rotating bar 42 rotates in the counterclockwise direction (as shown), the connecting bar 45 drives the unfolding bar 44 to rotate around the first axis 46 in the first direction (e.g., counterclockwise). Figure 4 Rotating counterclockwise (as shown) causes the protective part 4 to unfold. The drive unit 5 drives the rotating bar 42 to rotate around the first axis 46 in the second direction (as shown). Figure 4 When the rotating bar 42 rotates (in the clockwise direction shown), it pushes the unfolding bar 44 around the first axis of rotation 46 in the second direction (as shown by the connecting bar 45). Figure 4Rotate the protective part 4 in the clockwise direction (as shown) to bring it into the retracted state.
[0046] In some embodiments, the first end of each connecting bar 45 is rotatably connected to one of two adjacent unfolding bars 44, or rotatably connected to one of the fixed bar 41 and the unfolding bar 44 adjacent to the fixed bar 41, or rotatably connected to one of the rotating bar 42 and the unfolding bar 44 adjacent to the rotating bar 42. The second end of each connecting bar 45 is slidably connected to the other of two adjacent unfolding bars 44, or slidably connected to one of the fixed bar 41 and the unfolding bar 44 adjacent to the fixed bar 41, or slidably connected to one of the rotating bar 42 and the unfolding bar 44 adjacent to the rotating bar 42, so that when the linkage assembly 43 is retracted, the connecting bar 45 slides to be received in one of the two adjacent unfolding bars 44, or received in one of the fixed bar 41 and the unfolding bar 44 adjacent to the fixed bar 41, or received in one of the rotating bar 42 and the unfolding bar 44 adjacent to the rotating bar 42.
[0047] Specifically, the first end of the first connecting strip 45a (such as...) Figure 7 The right end of the first connecting strip 45a shown can be rotatably connected to one of the two adjacent unfolding strips 44 (such as...). Figure 7 The rightmost of the two adjacent unfolding strips 44 shown), the second end of the first connecting strip 45a (as shown) Figure 7 The left end of the first connecting strip 45a shown can be slidably connected to the other of the two adjacent unfolding strips 44 (such as...). Figure 7 The leftmost of the two adjacent unfolding bars 44 shown), so that when the protective part 4 is in the retracted state, the first connecting bar 45a can be accommodated in the other of the two unfolding bars 44 (e.g., Figure 7 The leftmost of the two adjacent unfolded strips 44 shown.
[0048] Furthermore, the first end of the second connecting strip 45b (as shown) Figure 7 The right end of the second connecting strip 45b shown can be rotatably connected to one of the fixed strip 41 and the unfolding strip 44 adjacent to the fixed strip 41 (e.g., Figure 7 The right side of the fixed strip 41 (shown as the unfolded strip 44), the second end of the second connecting strip 45b (as shown) Figure 7 The left end of the first connecting strip 45a shown can be slidably connected to the other of the fixed strip 41 and the unfolding strip 44 adjacent to the fixed strip 41 (e.g., Figure 7 (as shown by the fixing strip 41), so that when the protective part 4 is in the retracted state, the second connecting strip 45b can be accommodated in the other of the fixing strip 41 and the unfolding strip 44 adjacent to the fixing strip 41 (e.g., the fixing strip 41). Figure 7 (See fixing strip 41).
[0049] Furthermore, the first end of the third connecting strip 45c (such as...) Figure 7 The right end of the third connecting bar 45c shown can be rotatably connected to one of the rotating bar 42 and the unfolding bar 44 adjacent to the rotating bar 42 (e.g., Figure 7 The rotating bar 42 shown), the second end of the third connecting bar 45c (as shown) Figure 7 The left end of the third connecting bar 45c shown can be slidably connected to the other of the rotating bar 42 and the unfolding bar 44 adjacent to the rotating bar 42 (e.g., Figure 7 The rotating bar 42 shown has an unfolding bar 44 on the left side, so that when the protective part 4 is in the retracted state, the third connecting bar 45c can be accommodated in the other of the rotating bar 42 and the unfolding bar 44 adjacent to the rotating bar 42 (e.g., the unfolding bar 44 on the left side of the rotating bar 42). Figure 7 The rotating bar 42 shown has an unfolding bar 44 on the left side. This allows the protective part 4 to have a smaller volume when it is in the folded state.
[0050] Figure 8 A perspective view of the unfolding strip, connecting strip, and fixing strip according to an embodiment of the present invention is shown.
[0051] like Figures 1-8 As shown, in some embodiments, one of the two adjacent unfolding strips 44 (e.g. Figure 3 One of the two adjacent unfolding strips 44 shown, the right unfolding strip 44, the fixing strip 41, and the unfolding strip 44 adjacent to the fixing strip 41 (e.g. Figure 3 The fixed bar 41 shown has an unfolded bar 44 on the right side, and one of the rotating bar 42 and the unfolded bar 44 adjacent to the rotating bar 42 (as shown). Figure 3 The rotating bar 42 shown is formed for connecting the first end of the connecting bar 45 (e.g., Figure 3 The right end of the connecting strip 45 shown is rotatably connected to the rotating groove 49. The first end of the connecting strip 45 (as shown) Figure 3 The right end of the connecting strip 45 shown can be formed with a first protrusion 451 that matches the shape of the rotating groove 49. Based on the cooperation between the rotating groove 49 and the first protrusion 451, the connecting strip 45 can be positioned relative to one of the two adjacent unfolding strips 44 (such as...). Figure 3 One of the two adjacent unfolding strips 44 shown, the right unfolding strip 44, the fixing strip 41, and the unfolding strip 44 adjacent to the fixing strip 41 (e.g. Figure 3 The fixed bar 41 shown is the right-side unfolded bar 44), or one of the rotating bar 42 and the unfolded bar 44 adjacent to the rotating bar 42 (e.g., the unfolded bar 44 on the right side of the fixed bar 41 shown). Figure 3 The rotating bar 42 shown rotates.
[0052] like Figures 1-8 As shown, in some embodiments, the other of the two adjacent unfolded strips 44 (such as...) Figure 3The leftmost of the two adjacent unfolding strips 44 shown), the fixing strip 41, and the other of the unfolding strips 44 adjacent to the fixing strip 41 (e.g., Figure 3 The fixed bar 41 shown), and the rotating bar 42 and the unfolding bar 44 adjacent to the rotating bar 42 (as shown) Figure 3 The unfolded bar 44 on the left side of the rotating bar 42 shown has a receiving groove 48 for accommodating the connecting bar 45. The second end of the connecting bar 45 (as shown) Figure 3 The left end of the connecting strip 45 shown can be formed with a second protrusion 452 that matches the shape of the receiving groove 48. Based on the cooperation between the receiving groove 48 and the second protrusion 452, the second end of the connecting strip 45 (such as...) can be... Figure 3 The left end of the connecting strip 45 shown is relative to the other of the two adjacent unfolding strips 44 (such as...). Figure 3 The leftmost of the two adjacent unfolding strips 44 shown), the fixing strip 41, and the other of the unfolding strips 44 adjacent to the fixing strip 41 (e.g., Figure 3 The fixed bar 41 shown), and the rotating bar 42 and the unfolding bar 44 adjacent to the rotating bar 42 (as shown) Figure 3 The unfolding bar 44 on the left side of the rotating bar 42 shown slides, so that when the protective part 4 is in the retracted state, the connecting bar 45 is housed in the receiving groove 48.
[0053] Furthermore, the lengths of the connecting strips 45 can vary. The length of the connecting strip 45 closer to the first rotating shaft 46 can be shorter than the length of the connecting strip 45 farther from the first rotating shaft 46, thus creating a fan-shaped mesh structure when the protective part 4 is unfolded. When the protective part 4 is fully unfolded and blocks the through hole 21, the connecting strips 45 between two adjacent unfolding strips 44 can be parallel, the connecting strips 45 between the fixed strip 41 and the unfolding strip 44 adjacent to the fixed strip 41 can be parallel, and the connecting strips 45 between the rotating strip 42 and the unfolding strip 44 adjacent to the rotating strip 42 can be parallel. This increases the uniformity of the protective part 4 structure, thereby improving its stability. By adjusting the number of connecting strips 45, the protective part 4 can achieve different blocking effects; for example, it can both block the intrusion of tools and weapons and retain a certain observation gap.
[0054] like Figures 1-7 As shown, in some embodiments, when the protective part 4 is fully extended to block the through hole 21, the angle α formed by each connecting strip 45 and the fixing strip 41 in the first direction can be an obtuse angle. That is, the angle formed by each connecting strip 45 and the fixing strip 41 in the extended direction is an obtuse angle, so that when the protective part 4 is retracted, the connecting strip 45 can move closer to the fixing strip 41 based on its own weight, which can reduce the external force driving.
[0055] like Figures 4-8As shown, in some embodiments, an arc-shaped limiting groove 12 is formed within the accommodating space 11. A sliding member 47 matching the shape of the limiting groove 12 is provided on the side of the unfolding bar 44 and the rotating bar 42 away from the first rotating shaft 46. Further, arc-shaped limiting grooves 12 can be formed on both inner walls of the housing 1. The two ends of the sliding member 47 can be respectively disposed in the limiting grooves 12 on the inner walls of the two sides and can slide relative to the limiting grooves 12. The unfolding bar 44 and the rotating bar 42 rotate around the first rotating shaft 46 based on the cooperation of the limiting grooves 12 and the sliding member 47. By providing the sliding member 47 and the limiting groove 12, the unfolding bar 44 and the rotating bar 42 can be prevented from deviating from the preset trajectory, thereby improving the accuracy of the protective part 4 in retracting or unfolding.
[0056] Figure 9 It shows Figure 6 Enlarged view of point A in the middle. Figure 10 It shows Figure 4 Enlarged view of point B in the middle. Figure 11 A diagram showing the positional relationship between the drive unit, the elastic component, and the guide groove according to an embodiment of the present invention is provided. Figure 12 A perspective view of a moving member, a drive rod, and an elastic component according to an embodiment of the present invention is shown.
[0057] like Figures 6-12 As shown, in some embodiments, the drive unit 5 may include a drive assembly 51, a moving member 52, and a drive rod 53. The drive assembly 51 may include a motor 54 and a lead screw 55. The moving member 52 may be connected to the drive assembly 51 and may move along the drive assembly 51. Specifically, the moving member 52 is threadedly connected to the lead screw 55, and the moving member 52 may move along the lead screw 55. The drive rod 53 is movably disposed on the moving member 52. The moving member 52 may extend in a direction perpendicular to the lead screw 55. The drive rod 53 may extend in a direction perpendicular to the moving member 52. Specifically, the moving member 52 may have a sliding hole 56, and the drive rod 53 may slide within the sliding hole 56. The rotating bar 42 may have a strip-shaped hole 421. An extension plate 17 is formed within the housing 1, that is, an extension plate 17 is formed within the receiving space 11. The extension plate 17 has a guide groove 13. The drive rod 53 may pass through the guide groove 13 and connect to the strip-shaped hole 421. When the drive assembly 51 drives the moving part 52 to move along the drive assembly 51, the drive rod 53 moves along the guide groove 13, thereby driving the rotating bar 42 to rotate around the first rotating shaft 46 based on the cooperation between the strip hole 421 and the drive rod 53. By providing the drive part 5, the folding or unfolding of the protective part 4 can be achieved relatively quickly.
[0058] like Figures 6-12As shown, in some embodiments, the extension plate 17 may also have a groove 14 communicating with the guide groove 13. A locking hole 15 is formed on the side of the guide groove 13 opposite to the groove 14. The marine porthole also includes a resilient component 6 and an unlocking component 7. The resilient component 6 is telescopic. The resilient component 6 can extend from the groove 14 through the guide groove 13 to the locking hole 15. The unlocking component 7 can be disposed on the moving member 52 and extend in a direction perpendicular to the guide groove 13. The unlocking component 7 can be parallel to the drive rod 53. The housing 1 may also have a locking groove 16 that matches the shape of the unlocking component 7. The locking groove 16 can communicate with the guide groove 13, and during the movement of the moving member 52, the unlocking component 7 can move from the guide groove 13 to the locking groove 16 or from the locking groove 16 to the guide groove 13.
[0059] Furthermore, such as Figures 10-11 As shown, at the first end of the drive rod 53 guided by the guide groove 13 (as shown) Figure 10 The right end of the guide groove 13 shown) leads to the second end of the guide groove 13 (as shown). Figure 10 During the movement of the left end of the guide groove 13 shown, the drive rod 53 pushes the elastic component 6 into the groove 14. The locking groove 16 can engage with the second end of the guide groove 13 (such as the left end of the guide groove 13). Figure 10 The left end of the guide groove 13 (shown) is connected. When the drive rod 53 moves to the second end of the guide groove 13, the unlocking member 7 can be interference-fitted with the locking groove 16 to prevent the drive rod 53 from moving to the first end of the guide groove 13 based on the cooperation between the unlocking member 7 and the locking groove 16. Thus, when the drive unit 5 does not actively drive the moving member 52, it can ensure that the drive rod 53 does not move to the first end of the guide groove 13, thereby maintaining the stability of the deployed state. It can effectively prevent the protective unit 4 from being accidentally retracted due to ship turbulence, accidental switch activation, or external impact, ensuring the stability of the protective state. Furthermore, it can still provide protection even if the motor 54 is maliciously damaged and fails.
[0060] Furthermore, when the drive unit 5 drives the moving member 52 to move in the direction of the motor 54, the moving member 52 drives the drive rod 53 to move from the second end of the guide groove 13 to the first end of the guide groove 13. During this process, the unlocking member 7 can push the elastic component 6 into the groove 14, thereby allowing the drive rod 53 to continue to move towards the first end of the guide groove 13.
[0061] like Figures 10-12 As shown, in some embodiments, the elastic component 6 may include an elastic element 61 and a locking element 62. The elastic element 61 may be disposed in the groove 14 and on the side of the groove 14 away from the guide groove 13 (e.g., Figure 11 The upper side of the groove 14 shown is connected. The first end of the locking member 62 (as shown) Figure 11 The upper end of the locking member 62 shown is connected to the elastic member 61. The second end of the locking member 62 (as shown) Figure 11 The lower end of the locking element 62 shown passes through the guide groove 13 and is inserted into the locking hole 15.
[0062] like Figures 10-12 As shown, in some embodiments, the second end of the locking member 62 (e.g. Figure 11 The first side of the lower end of the locking member 62 shown (as shown) Figure 11 A first ramp 63 is formed on the right side of the lower end of the locking member 62 shown. The second side of the second end of the locking member 62 (as shown) Figure 11 A second ramp 64 is formed on the left side of the lower end of the locking member 62 shown. During the movement of the drive rod 53 from the first end of the guide groove 13 to the second end of the guide groove 13, the drive rod 53 abuts against the first ramp 63, thereby pushing the locking member 62 towards the groove 14. During the movement of the drive rod 53 from the second end of the guide groove 13 to the first end of the guide groove 13, the unlocking member 7 abuts against the second ramp 64, thereby pushing the locking member 62 towards the groove 14.
[0063] like Figures 10-11 As shown, the guide groove 13 may include a connected transverse groove 131 and an inclined groove 132. The transverse groove 131 may be located at the first end of the guide groove 13, and the inclined groove 132 may be located at the second end of the guide groove 13. The guide groove 13 may extend horizontally from the first end to the second end and then extend upward at an incline. By setting the inclined groove 132, the impact force on the porthole can be distributed to the housing 1, which can prevent components such as the rotating bar 42 and the motor 54 from being damaged due to excessive force, and can improve the stability and safety of the protective part 4.
