Multi-stage linkage electric sliding cover mechanism

Abstract

The present application relates to the technical field of electric sliding cover of shelter, in particular to a multi-stage linkage electric sliding cover mechanism. The multi-stage linkage electric sliding cover mechanism comprises multi-stage sliding plates, and realizes the linkage sliding of each layer of sliding plates in turn through a driving device and a collision mechanism, so as to realize the opening and closing of the whole sliding cover. The whole mechanism occupies small space, can cover large opening area, and has two seemingly contradictory and incompatible advantages of "large" and "space saving". The gear and the rack adopt the inverted meshing mode, which solves the problem of easy jamming of the traditional sliding cover mechanism to the greatest extent.

Description

Technical Field

[0001] This invention belongs to the field of electric sliding cover technology for modular hospitals, specifically relating to a multi-stage linkage electric sliding cover mechanism. Background Technology

[0002] Electric sliding covers, short for electric sliding cabin roof covers, are automatic opening and closing mechanisms installed on the top of modular shelters. They are widely used in modular shelter vehicles that require openings on the top. Existing electric sliding covers are generally single-layer structures. When opened, the cover occupies a large amount of space on the top of the modular shelter, and the span of the opening it covers is relatively small, making them unsuitable for modular shelters that require large openings on the top. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of existing electric sliding covers having a large space occupation and a small opening area that can be covered. Therefore, this invention proposes an electric sliding cover mechanism that has multi-level linkage, small space occupation, and can cover a large opening area.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multi-level linkage electric sliding cover mechanism is used to cover the opening of a shelter. It includes a multi-level sliding plate group, a driving device and a collision mechanism. The multiple sliding plates of the multi-level sliding plate group are stacked, and the bottommost sliding plate is a fixed plate, which is fixed to one side of the shelter opening.

[0006] The driving device is located on the lower surface of the uppermost sliding plate; the driving device includes a motor and a drive shaft; both ends of the second drive shaft are provided with third gears, and the top of the two side walls of the cabin opening are provided with racks, and the third gears mesh with the corresponding racks; the motor drives the third gears to move along the racks through the second drive shaft.

[0007] Furthermore, the drive device also includes a reducer, a first drive shaft, a first gear, and a second gear; the middle part of the first drive shaft is fixedly connected to the output end of the reducer; there are two first gears, located at both ends of the first drive shaft respectively; the first drive shaft drives the rotation of the second drive shaft through the meshing of the second gear and the first gear on the second drive shaft.

[0008] Furthermore, the collision mechanism includes a front impact block and a rear impact block. The front impact block is located at one end of the near-drive device on the lower surface of each sliding plate, and the front impact block and the sliding plate below it are on the same plane. The rear impact block is located at one end of the far-drive device on the lower surface of each sliding plate, and a limiting block is located at one end of the near-drive device on the upper surface of each sliding plate. When the container is sealed, the rear impact block is in close contact with the limiting block.

[0009] Furthermore, each sliding plate consists of two parts: a load-bearing frame and a skin; the skin is located on top of the load-bearing frame.

[0010] Furthermore, the third gear and rack adopt an inverted meshing structure.

[0011] Furthermore, the rack is provided with an integrated sliding guide rail; a guide wheel is installed on the lower surface of each sliding plate, and the guide groove of each guide wheel is constrained in the sliding guide rail of the rack.

[0012] Furthermore, an automatic winding mechanism is installed at the end of the fixed plate near the drive unit side, and the cable led out from the control box passes through the automatic winding mechanism before being connected to the motor.

[0013] Furthermore, a limit switch is provided at the end of the top sliding plate, and a stop block corresponding to the limit switch is provided on the side wall of the container; when the multi-level sliding plate assembly is extended to the limit position, the stop block abuts against the limit switch.

[0014] Furthermore, the skin of each sliding plate adopts a multi-bending structure, and a sealing strip is provided at the edge of each sliding plate end.

[0015] The design method of the multi-stage linkage electric sliding cover mechanism proposed in this invention has the following advantages:

[0016] Through multi-level linkage design, the length of each sliding cover plate is shortened. After the sliding cover is opened, the entire mechanism can be stacked and compressed into a small space. After the sliding cover is closed, it can cover a large span opening. It is suitable for occasions where the installation space on the top of the container is limited and the opening span of the container is large.

[0017] By installing the rack only on the top of the side wall of the container and installing other mechanisms on the end of the sliding cover, the space occupied by the mechanisms in the container is greatly reduced, and the space can be left for the equipment inside the container to the maximum extent.

[0018] By protecting the drive unit within a closed box-shaped cavity and employing an inverted meshing design between the third gear and the rack, the accumulation of sand and debris at the meshing point can be effectively prevented, significantly improving the protection of the transmission mechanism and preventing jamming during operation.

[0019] By integrating the sliding guide rail into the rack and installing guide wheels on each sliding plate, it can be fully ensured that each level of sliding plate slides along the planned straight trajectory, preventing the sliding plate from deviating from the track.

[0020] By employing a multi-bending structure for the outer skin of each sliding plate and installing sealing strips at the edges of each sliding plate, the waterproof and windproof properties of the sliding cover can be fully guaranteed. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] A multi-level linkage electric sliding cover mechanism is used to cover the opening of a container house. It includes a multi-level sliding plate group 2, a driving device 3 and a collision mechanism 4. Multiple sliding plates of the multi-level sliding plate group are stacked, and the bottommost sliding plate is a fixed plate, which is fixed to one side of the container house opening.

[0030] The driving device is located on the lower surface of the uppermost sliding plate; the driving device includes a motor and a drive shaft; both ends of the second drive shaft 306 are provided with third gears 307, and the top of the two side walls of the cabin opening are provided with racks, and the third gears mesh with the corresponding racks; the motor drives the third gears to move along the racks through the second drive shaft.

[0031] Furthermore, the drive device 3 also includes a reducer 302, a first drive shaft 303, a first gear 304, and a second gear 305; the middle part of the first drive shaft is fixedly connected to the output end of the reducer; there are two first gears, which are located at the two ends of the first drive shaft respectively; the first drive shaft drives the rotation of the second drive shaft through the meshing of the second gear 305 on the second drive shaft and the first gear.

[0032] Furthermore, the collision mechanism 4 includes a front impact block 401 and a rear impact block 402. The front impact block 401 is provided at one end of the near-drive device on the lower surface of each sliding plate, and the front impact block and the sliding plate below it are located on the same plane; the rear impact block 402 is provided at one end of the far-drive device on the lower surface of each sliding plate, and a limiting block is provided at one end of the near-drive device on the upper surface of each sliding plate; in the sealed state of the container, the rear block is in close contact with the limiting block.

[0033] Furthermore, the front surfaces of the limiting groove and the rear impact block are both blocking surfaces; the rear surfaces of the limiting groove and the rear impact block are both smooth arc surfaces.

[0034] Furthermore, each sliding plate consists of two parts: a load-bearing frame 201 and a skin 202; the skin is located on top of the load-bearing frame.

[0035] Furthermore, the third gear 307 and the rack 5 adopt an inverted meshing structure.

[0036] Furthermore, the rack 5 is provided with an integrated sliding guide rail; a guide wheel 6 is installed on the lower surface of each sliding plate, and the guide groove of each guide wheel 6 is constrained in the sliding guide rail of the rack 5.

[0037] Furthermore, an automatic winding mechanism 7 is installed at the end of the fixed plate 1 near the drive device 3. The cable led out from the control box passes through the automatic winding mechanism 7 and is then connected to the motor 301.

[0038] Furthermore, a limit switch 8 is provided at the end of the top sliding plate, and a stop block corresponding to the limit switch is provided on the side wall of the cabin; when the multi-level sliding plate group is unfolded to the limit position, the stop block abuts against the limit switch.

[0039] Furthermore, the skin 202 of each sliding plate 2 adopts a multiple bending structure, and a sealing strip 9 is provided at the edge of each sliding plate 2 end.

[0040] The following is a more specific embodiment:

[0041] like Figures 1 to 6As shown, the multi-stage linkage electric sliding cover mechanism of the present invention includes a primary fixed plate 1 and multiple sliding plates 2. The number of stages of the multi-stage sliding plates 2 can be calculated based on the actual installation space and the opening size of the top of the shelter. In this embodiment, the multi-stage sliding plates 2 are set to three stages, with the topmost sliding plate defined as the first-stage sliding plate. The fixed plate 1 is fixed to the top plate of the shelter where no opening is needed. The multi-stage sliding plates 2 are stacked layer by layer and movably connected above the fixed plate 1. The sequential linkage sliding of each layer of sliding plates is realized through the driving device 3 and the collision mechanism 4, thereby realizing the opening and closing of the entire sliding cover.

[0042] The drive unit 3 is located at the end of the first-stage sliding plate and includes a motor 301, a reducer 302, a first transmission shaft 303, a first gear 304, a second gear 305, a second transmission shaft 306, and a third gear 307. These drive units are installed in a box-shaped enclosed cavity with an upper cover, effectively enhancing the drive unit's adaptability to harsh environments such as wind, sand, rain, and snow. The third gear 307 is the output gear for the final rotary motion, meshing with a rack 5, which is mounted on the top of the side walls of the container. The working process of the drive unit is as follows: first, the output shaft of the motor 301 outputs rotary motion, which is reduced by the reducer 302 and then drives the first gear 304 to rotate via the first transmission shaft 303. The first gear 304 meshes with the second gear 305, driving the second gear 305, the second transmission shaft 306, and the third gear 307 to rotate. Finally, through the meshing of the third gear 307 with the rack 5, the rotary motion of the gears is converted into the linear motion of the sliding plate. By setting up two-stage drive shafts, the span of each drive shaft can be reduced, while further decelerating the rotational motion.

[0043] The third gear 307 and rack 5 adopt an inverted meshing structure, which can effectively prevent the accumulation of sand and debris at the meshing point and effectively prevent the transmission mechanism from jamming.

[0044] The collision mechanism 4 includes a front impact block 401 and a rear impact block 402. A set of collision mechanisms 4 is installed on each side of the bottom of each sliding plate. The front impact block 401 is installed at the end closer to the drive device 3, and the rear impact block 402 is installed at the end farther from the drive device 3. When the sliding cover needs to be opened, the drive device 3 first drives the first sliding plate to move linearly in the opening direction. When the first sliding plate is about to finish its stroke, its front impact block strikes the front impact block of the second sliding plate, thus driving the second sliding plate to continue moving linearly, and so on, until the last sliding plate moves linearly. When the last sliding plate finishes its stroke, the sliding cover is fully opened. When the sliding cover needs to be closed, the drive device 3 first drives the first sliding plate to move linearly in the closing direction. When the first sliding plate is about to finish its stroke, its rear impact block strikes the front impact block of the second sliding plate, thus driving the second sliding plate to continue moving linearly, and so on, until the last sliding plate moves linearly. When the last sliding plate finishes its stroke, the sliding cover is fully closed.

[0045] Each stage of the multi-stage sliding plate 2 consists of two parts: a load-bearing frame 201 and a skin 202. In this embodiment, the load-bearing frame 201 is made of stainless steel pipe welded together, and the skin 202 is made of stainless steel sheet. The two are riveted and welded together, which can effectively reduce weight and significantly improve corrosion resistance while ensuring load-bearing capacity.

[0046] The rack 5 includes an inverted rack 501 and a rack mounting component 502. The inverted rack 501 is provided with a protruding sliding guide rail, and guide wheels 6 are installed on each level of sliding plate 2. The guide grooves of the guide wheels 6 are engaged in the sliding guide rails of the inverted rack 501, thereby ensuring that each level of sliding plate can move along the planned linear trajectory.

[0047] An automatic cable winding mechanism 7 is installed at the end of the fixed plate 1. Specifically, it is located at the end of the fixed plate 1 near the drive device. The cable led out from the control box passes through the automatic cable winding mechanism 7 and is then connected to the motor 301, ensuring the smooth winding and unwinding of the control cable and power cable during the sliding of the sliding top cover.

[0048] The end of the first-stage sliding plate is also provided with a limit switch 8 to realize the limit control of the sliding cover.

[0049] The skin 202 of the multi-level sliding plate 2 adopts a multiple bending structure, and sealing strips 9 are installed at the edges of each level of the sliding plate to ensure the waterproof and windproof properties of the sliding top cover.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
