[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0035] like Figure 1-7 As shown, the hatch cover 2 support structure includes: a fixed base 1, a drive assembly 3, a telescopic mechanism 4, and a locking assembly 5. The cover 2 is hinged to the top of the fixed base 1; the drive assembly 3 is installed on the side surface of the fixed base 1; the telescopic mechanism 4 is installed on the side surface of the fixed base 1, and a moving part 6 is installed at the end of the telescopic mechanism 4. The moving part 6 is slidably disposed in a slide rail 7, and the slide rail 7 is fixedly connected to the side surface of the cover 2; the locking assembly 5 is installed on the side surface of the telescopic mechanism 4, and the locking assembly 5 is used to lock and fix the telescopic mechanism 4 after it has been extended or retracted.

[0036] The drive assembly 3 includes a servo motor 31, a lead screw 32, a drive base 33, and a support plate 35. The servo motor 31 is fixedly mounted on the side surface of the fixed base 1. The output end of the servo motor 31 is connected to the lead screw 32. The drive base 33 is threaded onto the surface of the lead screw 32. The top side of the drive base 33 is connected to the telescopic mechanism 4 through the support plate 35.

[0037] In use, after the servo motor 31 is started, its output end drives the lead screw 32 to rotate around its own axis. When the lead screw 32 rotates, the drive seat 33 moves linearly along the axis of the lead screw 32. The linear motion of the drive seat 33 is converted into the angular rotation of the support plate 35, which facilitates the adjustment of the angle of the telescopic mechanism 4 by the support plate 35, thereby realizing the adjustment of the rotation angle of the telescopic mechanism 4 and thus initially controlling the opening and closing range of the cover plate 2.

[0038] The bottom end of the support plate 35 is connected to the drive seat 33 through the first rotating member 34, and the top end of the support plate 35 is equipped with a second rotating member 36. The support plate 35 is rotatably connected to the bottom side of the telescopic mechanism 4 through the second rotating member 36.

[0039] The first rotating member 34 and the second rotating member 36 are hinges.

[0040] The telescopic mechanism 4 includes a connecting frame 41, a rotating seat 42, a telescopic cylinder 43, and a telescopic rod 44. The connecting frame 41 is fixedly connected to the side surface of the fixed seat 1. A rotating shaft is fixedly connected to the inner wall of the connecting frame 41. The rotating seat 42 is sleeved on the surface of the rotating shaft. The telescopic cylinder 43 is fixedly connected to the end of the rotating seat 42. The telescopic rod 44 is slidably connected to the inner cavity of the telescopic cylinder 43. Multiple locking grooves 45 are opened on the side surface of the telescopic rod 44. The end of the telescopic rod 44 is hinged to the moving part 6 through a third rotating member 46. A hydraulic cylinder 47 is fixedly installed inside the telescopic cylinder 43. The output end of the hydraulic cylinder 47 is fixedly connected to the end of the telescopic rod 44.

[0041] The third rotating component 46 includes a third rotating frame, a third shaft, and a third rotating block. The third rotating frame is fixedly connected to the moving part 6. The third shaft is fixedly connected to the inner wall of the third rotating frame. The third rotating block is rotatably sleeved on the surface of the third shaft. The third rotating block is fixedly connected to the end of the telescopic rod 44.

[0042] In this embodiment, the connecting frame 41 is fixed to the side surface of the fixed base 1, and the rotation axis of its inner wall provides a rotation fulcrum for the rotating base 42. The rotating base 42 can rotate freely around the rotation axis. When the hydraulic cylinder 47 extends, it pushes the telescopic rod 44 to slide outward along the inner cavity of the telescopic cylinder 43 (the telescopic mechanism 4 extends); when the hydraulic cylinder 47 retracts, it pulls the telescopic rod 44 to slide inward (the telescopic mechanism 4 shortens). Since the angle of the cover plate 2 will continuously change when it rotates, the third rotating component 46 can realize the flexible rotation between the telescopic rod 44 and the moving part 6, avoiding structural jamming due to angle misalignment. The multiple locking grooves 45 on the side surface of the telescopic rod 44 are used to cooperate with the locking component 5 to fix the telescopic length, thereby satisfying the adjustment of the overall length of the telescopic mechanism 4, thereby fine-tuning the rotation angle of the cover plate 2, and at the same time providing stable support for the cover plate 2.

[0043] The locking assembly 5 includes a locking seat 51, a connecting plate 54, an elastic spring 55, a positioning seat 56, a fixing bolt 57, and a fixing head 58. The locking seat 51 is slidably connected to the side surface of the telescopic cylinder 43. The connecting plate 54 is fixedly connected to the outer end of the locking seat 51. The connecting plate 54 is elastically connected to the side surface of the telescopic cylinder 43 through the elastic spring 55. The side surface of the locking seat 51 is provided with a first fixing hole 52. A positioning seat 56 is fixedly installed on the side surface of the telescopic cylinder 43 on one side of the locking seat 51. A fixing bolt 57 is threaded through the surface of the positioning seat 56. A fixing head 58 is fixedly connected to the end of the fixing bolt 57.

[0044] The locking seat 51 is slidably connected to the side surface of the telescopic cylinder 43. The elastic springs 55 on both sides of the locking seat 51 are always in a pre-tight state, applying a pulling / pushing force to the inside of the telescopic cylinder 43, so that the inner end of the locking seat 51 engages with the surface of the telescopic rod 44, thereby fixing the telescopic rod 44 to the telescopic cylinder 43. During the fixing of the telescopic rod 44, the fixing bolt 57 is rotated, and the fixing bolt 57 pushes the fixing head 58 to engage in the second fixing hole 53, completely fixing the position of the locking seat 51 and preventing it from coming out of the locking groove 45, thereby locking the length of the telescopic mechanism 4. When retracting the telescopic rod 44, the locking seat 51 is pulled, and at the same time the fixing bolt 57 pushes the fixing head 58 to engage with the first fixing hole 52, and the locking seat 51 disengages from the locking groove 45 on the side surface of the telescopic rod 44, making it easier to retract the telescopic rod 44.

[0045] The first fixing hole 52 and the second fixing hole 53 have the same structure, and the first fixing hole 52 and the second fixing hole 53 can be engaged with the end of the fixing head 58.

[0046] The inner end of the locking seat 51 has a triangular cross-section. The inner end of the locking seat 51 is engaged with the locking groove 45. Elastic springs 55 are symmetrically arranged on both sides of the locking seat 51.

[0047] The moving part 6 includes a movable slider 61, a fixed shaft 62 and a roller 63. The movable slider 61 is slidably connected to the inner cavity of the slide rail 7. The fixed shaft 62 is fixedly connected to the side surface of the movable slider 61. The roller 63 is sleeved on the surface of the fixed shaft 62 and can roll on the side surface of the slide rail 7.

[0048] The movable slider 61 is slidably connected to the slide rail 7. When the telescopic mechanism 4 extends, retracts, or rotates, the movable slider 61 slides along the inner cavity of the slide rail 7, providing a stable guide path for the rotation of the cover plate 2. When the movable slider 61 slides, the roller 63 contacts the side surface of the slide rail 7, converting sliding friction into rolling friction, greatly reducing frictional resistance, preventing the movable slider 61 from getting stuck, eliminating frictional obstacles during the rotation of the cover plate 2, and improving the smoothness and stability of the overall movement.

[0049] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.

[0050] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
