Description

Technical Field

[0001] This utility model relates to the field of hatch technology, and in particular to an upward-opening and closing structure for a hatch. Background Technology

[0002] A hatch opening and closing structure refers to a mechanical device system used to control the opening and closing of hatches. Its core functions include: a. providing stable installation and motion guidance to ensure that the hatch maintains the correct trajectory during opening and closing; b. driving the hatch to complete the opening and closing action through electric, hydraulic or manual drive; c. achieving reliable locking in the closed state, and may integrate sealing structures, etc.

[0003] In existing hatch opening and closing structures, the sliding rails are mostly linear, which are prone to falling off or wearing out when the hatch is flipped. In addition, the lack of linkage installation components makes the hatch prone to deflection or jamming when it moves. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the problems of poor door movement stability and simple sliding guide structure in the prior art mentioned above, an upward opening and closing structure for the door is provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an upward-opening and closing structure for a hatch, including a hatch body, the hatch body being installed at the front end of the opening and closing structure, the opening and closing structure being provided with a support frame and an installation assembly, the support frame including a left support plate and a right support plate, the front part of the right support plate being provided with a horizontal "7"-shaped sliding groove, the two ends of the installation assembly being provided with a left transition frame and a right transition frame respectively, the right transition frame being provided with a sliding member extending into the sliding groove and sliding along the sliding groove, the right support plate being provided with a driving mechanism for moving the right transition frame, and the left transition frame being provided with a limiting member for limiting the installation assembly.

[0006] The left and right support plates form a stable double-sided support frame, ensuring that the hatch body is subjected to balanced forces during opening and closing, and avoiding deformation or wear caused by stress concentration on one side. The horizontal "7"-shaped groove on the right support plate cooperates with the sliding parts to realize a compound motion trajectory of the hatch first moving horizontally and then flipping upward, which saves opening space and avoids interference with the surrounding structure. The drive mechanism acts directly on the right transition frame, combined with the limiting parts of the left transition frame, to achieve coordinated control of power transmission and position locking, and improve motion accuracy.

[0007] According to one embodiment of the present invention, the installation assembly further includes a crossbeam, a left connecting seat, and a right connecting seat. The crossbeam connects the left transition frame and the right transition frame. The left connecting seat and the right connecting seat are respectively disposed on the outer surfaces of the left transition frame and the right transition frame, and are both connected to the inner wall of the hatch body.

[0008] The crossbeam connects the left and right transition frames into a whole, enhancing the torsional resistance of the installation components and preventing the hatch from swaying; the left and right connecting seats evenly distribute the load of the hatch body to the support frame, reducing local stress.

[0009] According to one embodiment of this utility model, a slide rail is provided on the outer side of the left support plate, and a left sliding plate is connected to the left transition frame. A slider is provided at the lower part of the left sliding plate that slides along the slide rail. The cooperation between the left sliding plate and the slide rail complements the sliding groove function of the right support plate, forming a double-sided synchronous guide to prevent the hatch from tilting.

[0010] According to one embodiment of this utility model, a slot is provided on the left support plate to cooperate with the limiting member. The mechanical cooperation between the limiting member and the slot provides physical locking when the hatch is fully opened or closed, without relying on electronic sensors.

[0011] According to one embodiment of the present invention, the limiting member is a pin, which forms a locking or releasing engagement with the slot.

[0012] According to one embodiment of this utility model, a second slide rail is provided on the outer surface of the right support plate, and a right sliding plate is connected to the right transition frame. A second slider is provided at the lower part of the right sliding plate, which slides along the second slide rail. The cooperation between the right sliding plate and the second slide rail serves as an auxiliary guide for the "7"-shaped slide groove, ensuring smooth movement even under extreme loads.

[0013] According to one embodiment of the present invention, the driving mechanism includes a drive motor, a transmission gear assembly, and a connecting rod assembly. The drive motor is mounted on the inner side of the right support plate, and a driving gear is provided on its output shaft. The transmission gear assembly includes a gearbox and a driven gear, a worm, and a worm wheel disposed in the gearbox. The driven gear meshes with the driving gear and is coaxially arranged with the worm. The worm wheel is mounted on a worm wheel shaft and meshes with the worm. One end of the worm wheel shaft passes through the right support plate and is connected to one end of the connecting rod assembly. The other end of the connecting rod assembly is connected to the right transition frame.

[0014] The meshing structure of the worm gear and worm wheel prevents reverse rotation, ensuring the hatch remains stationary in any position. The gear set amplifies the motor torque, making it suitable for driving heavy hatches.

[0015] According to one embodiment of this utility model, a manual device is also included. The manual device comprises a handle, a bevel gear pair, and a transmission rod. The lower end of the handle shaft is connected to the driving bevel gear of the bevel gear pair, and the driven bevel gear of the bevel gear pair is mounted on the bevel gear shaft. One end of the transmission rod is connected to the bevel gear shaft via a universal joint, and the other end is connected to the worm gear shaft via a universal joint. Manual input is transmitted to the worm gear shaft through the bevel gear pair and the universal joint, allowing operation even when power is off.

[0016] According to one embodiment of this utility model, the sliding member is a roller or a slider, which is in clearance fit with the sliding groove. The clearance fit of the roller or slider allows for slight deformation and avoids jamming.

[0017] According to one embodiment of this utility model, an upper crossbeam and a lower crossbeam are connected between the left support plate and the right support plate, and a fixing cover is connected to the outer surface of the hatch body. The upper and lower crossbeams enhance the overall rigidity of the support frame, and the fixing cover protects the internal mechanism from environmental influences.

[0018] The beneficial effects of this utility model are:

[0019] This utility model solves the jamming problem caused by single-sided drive in traditional hatches through the coordinated design of double-sided support, composite slide groove and worm gear self-locking, reduces mechanical failure rate, improves safety, extends maintenance cycle and reduces operation and maintenance costs.

[0020] The combination of the “7”-shaped slide and the upward movement optimizes the movement path, saves opening space, and improves reliability.

[0021] The parallel design of electric drive and manual device allows operation even during power outages.

[0022] Mechanical limit switches replace electronic sensors, reducing manufacturing costs. Attached Figure Description

[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0034] like Figure 1 As shown, the hatch's upward-opening and closing structure includes a hatch body 1, which is installed at the front end of the opening and closing structure. The opening and closing structure is equipped with a support frame 2 and an installation component 3. A fixing cover 6 is connected to the outer surface of the hatch body 1.

The crossbeam 33 connects the left transition frame 31 and the right transition frame 32. The left connecting seat 34 and the right connecting seat 35 are respectively located on the outer surfaces of the left transition frame 31 and the right transition frame 32, and are both connected to the inner wall of the hatch body 1. The right transition frame 32 is provided with a sliding member 321 that extends into and slides along the slide groove 221. The sliding member 321 is a roller or a slider, and is clearance-fitted with the slide groove 221. The right transition frame 32 is connected to a right sliding plate 322, and the lower part of the right sliding plate 322 is provided with a slider 323 that slides along the slide rail 222. The left transition frame 31 is connected to a left sliding plate 312, and the lower part of the left sliding plate 312 is provided with a slider 313 that slides along the slide rail 211.

[0037] like Figure 6 As shown, the left transition frame 31 is provided with a limiting member 311 of the limiting installation assembly 3. Specifically, the left support plate 21 is provided with a slot 212 that cooperates with the limiting member 311. The limiting member 311 is a pin and forms a locking or releasing cooperation with the slot 212.

[0038] like Figure 7 As shown, the drive mechanism 4 includes a drive motor 41, a transmission gear assembly 42, and a connecting rod assembly 43. The drive motor 41 is mounted on the inner side of the right support plate 22, and its output shaft is equipped with a driving gear 411. The transmission gear assembly 42 includes a gearbox 421 and a driven gear 422, a worm 423, and a worm wheel 424 disposed within the gearbox 421. The driven gear 422 meshes with the driving gear 411 and is coaxially arranged with the worm 423. The worm wheel 424 is mounted on a worm wheel shaft 425 and meshes with the worm 423. One end of the worm wheel shaft 425 passes through the right support plate 22 and is connected to one end of the connecting rod assembly 43. The other end of the connecting rod assembly 43 is connected to the right transition frame 32. Specifically, the connecting rod assembly 43 is composed of two connecting rods.

[0039] like Figure 8 As shown, the manual device 5 includes a handle 51, a bevel gear pair 52, and a transmission rod 53. The lower end of the handle 51 shaft is connected to the driving bevel gear 521 of the bevel gear pair 52, and the driven bevel gear 522 of the bevel gear pair 52 is mounted on the bevel gear shaft 523. One end of the transmission rod 53 is connected to the bevel gear shaft 523 through a universal joint 531, and the other end is connected to the worm gear 423 shaft through a universal joint 531.

[0040] Specific work process:

[0041] Initial state: The hatch body 1 is in a horizontally closed state, and the limiting piece 311 on the left transition frame 31 is inserted into the slot 212 of the left support plate 21 to prevent the hatch from being opened accidentally. The drive motor 41 is not started, the worm gear 424 and worm 423 are in a self-locking state, and the connecting rod assembly 43 has no displacement.

[0042] Electric opening: When the drive motor 41 is powered on, the output shaft drives the drive gear 411 to rotate, which is transmitted to the driven gear 422 through meshing. The driven gear 422 is coaxial with the worm 423, driving the worm 423 to rotate, which in turn drives the worm wheel 424 to rotate. The rotation of the worm wheel 424 is transmitted to the connecting rod assembly 43 through the worm wheel shaft 425, which pulls the right transition frame 32 to move along the slide groove 221. The sliding member 321 slides along the vertical part of the slide groove 221. The hatch body 1 flips up with the left connecting seat 34 and the right connecting seat 35 as the axis. After flipping up, the sliding member 321 slides along the horizontal part of the slide groove 221. At the same time, the second slider 323 of the right sliding plate 322 slides along the second slide rail 222, and the first slider 313 of the left sliding plate 312 moves up synchronously along the first slide rail 211 to ensure balance on both sides. Until the sliding member 321 reaches the rear end of the slide groove 221, the drive motor 41 stops, and the worm gear 424 and worm 423 self-lock to prevent the hatch body 1 from falling back due to gravity.

[0043] Electric closing: The drive motor 41 rotates in the opposite direction, which drives the worm wheel 424 to rotate in the opposite direction through the rotation of the gear set, the driving gear 411, the driven gear 422 and the worm 423. The connecting rod assembly 43 pushes the right transition frame 32, the sliding member 321 enters the horizontal part of the slide groove 221, the hatch body 1 moves horizontally, the sliding member 321 slides down along the vertical part of the slide groove 221, and the hatch body 1 flips down; the limiting member 311 re-engages into the slot 212 to achieve fixation.

[0044] Manual emergency operation (in case of power failure or malfunction): Turn the handle 51, and the driving bevel gear 522 will change the transmission direction through the driving bevel gear 521 of the bevel gear pair 52. The transmission rod 53 will transmit the rotation to the worm shaft 423 through the universal joint 531, replacing the motor drive. The worm 423 will drive the worm wheel 424 to rotate. The subsequent movement trajectory is the same as the electric mode, but the handle 51 needs to be turned manually continuously.

[0045] The “7”-shaped slide 221 enables the door to first flip upwards and then move horizontally, avoiding interference between the door and the surrounding structure; the left sliding plate 312 and the right sliding plate 322 slide on the slide rail 1 211 and slide rail 222 respectively, ensuring that the door does not move skewed and preventing one-sided jamming; the electric and manual dual modes cover all working conditions; the worm gear drive automatically locks when the power supply is stopped, without the need for additional energy consumption to maintain the position.

[0046] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
