[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a movable surface covering mechanism to prevent slippage during the winding of the cover part.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a movable surface covering mechanism, including a covering component, two tracks disposed on both sides of the surface to be covered, and a support horizontally disposed between the two tracks. The support includes two frames that move on the corresponding tracks, and a cylinder is rotatably connected between the two frames. A tubular motor is fixedly connected to one of the frames, the tubular motor is located inside the cylinder, and the output end of the tubular motor is drively connected to the cylinder. One end of the covering component is fixed to the surface to be covered, and the other end of the covering component is connected to the cylinder. The support is equipped with a power unit to drive the support to move along the length of the track.

[0005] As a further improvement of this utility model, the two frames are integrally formed with a first support column and a second support column on opposite sides. The first support column is in the shape of a through tube. The outer shell of the tubular motor extends to the first support column and is fixed thereon.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] Reference Figures 1 to 9 As shown, the movable surface covering mechanism of this embodiment includes a covering 1, two tracks 2 disposed on both sides of the surface to be covered, and a support disposed laterally between the two tracks 2. The width of the covering 1 is greater than or equal to the surface to be covered, so that the covering 1 can cover the entire surface to be covered. The track 2 is installed on opposite sides of the surface to be covered by screws; The support includes two frames 3 that move on corresponding tracks 2. A cylinder 4 is rotatably connected between the two frames 3. The length of the cylinder 4 is greater than or equal to the width of the cover 1. A tubular motor 5 is fixedly connected to one of the frames 3. The tubular motor 5 is located inside the cylinder 4, and the output end of the tubular motor 5 is connected to the cylinder 4 for transmission. The tubular motor 5 drives the cylinder 4 to rotate, thereby realizing the rolling and unfolding of the cover 1. The tubular motor 5 includes a motor and a reducer. The reducer can be a planetary gear reducer. One end of the cover 1 is fixed to the surface to be covered, such as one end of a swimming pool. The track 2 is located on opposite sides of the pool. The other end of the cover 1 is connected to the cylinder 4 to prevent the cover 1 from separating from the cylinder 4. The cover 1 and the cylinder 4 can be fixed together or connected by a slot. For example, a slot is provided on the cylinder 4, and a locking strip is formed at one end of the cover 1. The locking strip is inserted into the slot to fix the two together. The support frame is equipped with a power unit to drive the support frame to move along the length of track 2.

[0019] The power that drives the support to move is separated from the power that drives the cylinder 4 to rotate. The speed at which the support moves along the length of the track 2 is constant. The rotation speed of the cylinder 4 driven by the tubular motor 5 changes with the size of the outer diameter formed by the cover 1 being rolled up on the cylinder 4. This allows the movement of the support to be synchronized with the progress of the cover 1 being rolled up or unrolled, ensuring that the cover 1 is always taut and will not bend.

[0020] Reference Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, the two frames 3 are integrally formed with a first support column 31 and a second support column 32 on their opposite sides. The first support column 31 is a through tube to facilitate the wiring of the tubular motor 5. The wire at the tail of the tubular motor 5 can extend out of the corresponding frame 3 through the first support column 31 to connect to the external power source. The outer shell of the tubular motor 5 extends to the first support column 31 and is fixed thereto. The tubular motor 5 is fixed by the first support column 31. The cylinder 4 is rotatably connected between the first support column 31 and the second support column 32. The cylinder 4 is also a hollow tube. The first support column 31 and the second support column 32 are both inserted into the two ends of the cylinder 4.

[0021] Reference Figure 3 , Figure 4 and Figure 6As shown, the output end of the tubular motor 5 is fixedly connected to a rotating wheel 51. Multiple ribs 41 are arranged circumferentially inside the cylinder 4. The rotating wheel 51 is engaged with the ribs 41. Multiple limiting grooves are opened circumferentially on the rotating wheel 51, and the limiting grooves correspond to the ribs 41. Thus, when the tubular motor 5 works, the tubular motor 5 drives the rotating wheel 51 to rotate, and the rotation drives the cylinder 4 to rotate, thereby realizing the winding and unfolding of the cover 1.

[0022] In one embodiment of the power unit, the power unit includes a first motor 61, two flexible belts 62, and two sets of power gears 63 and transmission gears 64. The two ends of the flexible belts 62 are fixed to the two ends of the corresponding tracks 2. The power gears 63 and transmission gears 64 in the same set mesh with each other and are rotatably connected to the corresponding frame 3. The power gears 63 and transmission gears 64 are connected to the frame 3 through bearings. A first transmission rod 65 is connected between the two power gears 63. The first motor 61 is rotatably connected to one of the power gears 63. The power gear 63 is rotatably connected to the corresponding flexible belt 62. When the first motor 61 drives the power gear 63 on it to rotate, it will drive the other power gear 63 to rotate through the first transmission rod 65, so that both transmission gears 64 rotate. In one embodiment, the flexible belt 62 is a toothed belt with its teeth facing upwards. The power gear 63 meshes with the flexible belt 62, and the flexible belt 62 is always embedded in the corresponding track 2, so that when the transmission gear 64 rotates, the bracket will move synchronously.

[0023] In another embodiment, a belt gear 66 is integrally formed on the transmission gear 64, and a flexible belt 62 meshes with the top of the belt gear 66. The flexible belt 62 is also a toothed belt with its teeth facing downwards, passing over the belt gear 66 from above, and exerting a downward pressure on the belt gear 66. This can prevent the bracket from detaching from the track 2 and prevent the flexible belt 62 from slipping on the belt gear 66.

[0024] At least two positioning wheels 33 are rotatably connected to the frame 3. The positioning wheels 33 are connected to the frame 3 through bearings. The two positioning wheels 33 are located at the two ends of the bottom of the frame 3, thereby maximizing the spacing between the two positioning wheels 33 in the same frame 3. For belt gears 66 at the same height, the deformation of the flexible belt 62 can be reduced. The positioning wheel 33 presses against the flexible belt 62 on the corresponding track 2, and the two positioning wheels 33 and the belt gear 66 form a triangle, which improves the stability of the support during the movement process.

[0025] Reference Figure 2As shown, the positioning wheel 33 includes an integrally formed protruding edge 331. The protruding edge 331 is located on the outside of the corresponding track 2 and fits against it. The protruding edge 331 is arranged circumferentially along the positioning wheel 33, which limits the interval distance between the two frames 3, so that the two frames 3 will not deviate in direction or leave the track 2 during the movement of the two frames 3 along the length direction of the track 2.

[0026] Multiple crossbars connect the two frame structures 3 to improve the stability of the connection between them.

[0027] Reference Figure 9 As shown, a first groove is provided on the track 2, and the edge of the cover 1 is located between the flexible strip 62 and the corresponding track 2. At least part of the flexible strip 62 is embedded in the corresponding first groove, and the edge of the cover 1 is also embedded in the corresponding first groove. The cover 1 is pressed by the corresponding flexible strip 62, so that the sealing between the cover 1 and the covered surface is better.

[0028] The track 2 has a second groove 21 and a third groove 22 that are interconnected. The flexible strip 62 is embedded in the corresponding second groove 21, and the edge of the cover 1 is embedded in the corresponding third groove 22. When the cover 1 is wide, its middle part will sag. After the edge of the cover 1 is embedded in the corresponding third groove 22, the edge of the cover 1 is locked, reducing the sag of the middle part of the cover 1 and making the cover 1 flat.

[0029] In another embodiment of the power unit, the power unit includes a second motor and two output gears. The two output gears are rotatably connected to the corresponding frame 3. A second transmission rod is connected between the two output gears. A rack is provided on the track 2. The rack can be integrally formed on the track 2 or installed later. That is, the track 2 and the rack can be a whole or composed of two or more parts. The rack meshes with the corresponding output gear, and the output end of the second motor is connected to one of the output gears. One or more transmission gears can be set between the output end of the second motor and the corresponding output gear to achieve speed reduction and other effects.
