[0037] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0038] Example:

[0039] See also Figure 1 As shown, this embodiment provides an outdoor rainproof, symmetrical double-door skylight structure, comprising a window frame 1 and two door panels 2 mounted on the window frame 1. The window frame 1 includes two end beams 11 and two side beams 12; the end beams 11 are arranged parallel to each other, and the side beams 12 are arranged parallel to each other; the end beams 11 and the side beams 12 are arranged to form a rectangular frame structure. The upper walls of the door panels 2 are raised upward to form a convex surface 21. When the door panels 2 are closed, the convex surface 21 is flush with the outer panel surface of the cabinet.

[0040] The skylight structure further includes:

[0041] The screw motion module 3 is installed on the window frame 1, and the two door panels 2 are connected to the screw motion module 3. The screw motion module 3 is used to drive the two door panels 2 along the length direction of the side beam 12, and at the same time move toward / away from each other to realize the closing / opening of the two door panels 2. Specifically, when the two door panels 2 move away from each other, they are in the open state, and when the two door panels 2 move toward each other, they are in the closed state.

[0042] The trough 4 is provided on the side wall of the end beam 11 of the window frame 1 and extends along the length of the end beam 11. The upper end of the trough 4 is open and fixed to the outer wall of the end beam 11 by screws. The trough 4 is mainly used to collect rainwater. The ends of the trough 4 are closed, and the bottom of the trough 4 is provided with an outlet pipe 41 connected to the trough 4. In this way, rainwater collected in the trough 4 can be discharged through the outlet pipe 41.

[0043] The guide grooves 5 comprise two sets, one on each side of the side beam 12 and extending along the length of the side beam 12. The guide grooves 5 are V-shaped with an open top and are fixed to the outer side of the side beam 12 with screws. Rainwater on the door panel 2 flows to the sides and falls into the guide grooves 5.

[0044] The end of the diversion trough 5 away from the water collection trough 4 is closed, and the end of the diversion trough 5 close to the water collection trough 4 extends to the upper part of the water collection trough 4, so that the rainwater in the diversion trough 5 can flow along the diversion trough 5 to one end of the water collection trough 4 and finally flow into the water collection trough 4.

[0045] The side walls of the two door panels 2 on opposite sides are both provided with water stop grooves 6 extending along the width direction of the door panels 2 , wherein the width direction of the door panels 2 refers to the direction in which the door panels 2 are parallel to the end beams 11 .

[0046] The upper part of the water stop groove 6 is open; the two ends of the water stop groove 6 are open, and the two ends of the water stop groove 6 extend to the upper part of the two guide grooves 5. In this way, when rainwater on the door panel 2 flows toward the side of the water stop groove 6, it will eventually fall into the water stop groove 6 and then flow into the guide groove 5 from the water stop groove 6.

[0047] In this embodiment, in order to ensure the sealing of the closing portion of the two door panels 2 when the two door panels 2 are closed, this embodiment is further improved, specifically:

[0048] Reference Figure 9 As shown, on the opposite sides of the two door panels 2, one of the door panels 2 has a sunken step 23 on its lower wall. Figure 7 As shown, the upper wall of the other door panel 2 has an upper sunken step 24 that matches the lower sunken step 23. When closed, the lower sunken step 23 covers the upper part of the upper sunken step 24, and the two are butted and overlapped.

[0049] like Figure 7 As shown, a sealing groove 25 extending along the length of the upper step 24 is formed on the bottom wall of the upper step 24. A sealing strip (not shown) is embedded in the sealing groove 25, wherein the sealing strip can be a rubber strip. When the door panel 2 is closed, the two steps are butted together, and the lower step 23 presses against the sealing strip in the sealing groove 25 of the upper step 24 to achieve a seal, preventing rainwater from leaking through the gap between the two door panels 2.

[0050] like Figure 1 and Figure 3 As shown, in order to make the rainwater of the door panel 2 flow better into the guide groove 5, in this embodiment, a guide groove 22 inclined to one side of the guide groove 5 is opened on the upper wall of the door panel 2 near the guide groove 5, and the rainwater flows into the guide groove 5 through the inclined surface of the guide groove 22.

[0051] In this embodiment, combined with Figure 2 As shown, the screw motion module 3 includes two bidirectional screws 31 that are rotatably connected to the inner sides of the two side beams 12, and a stepper motor 32 installed on the window frame 1 to drive the bidirectional screw 31 to rotate; it should be noted that the bidirectional screw 31 refers to a screw with two opposite thread segments on the rod wall, that is, one segment is a positive thread and the other segment is a negative thread; and the two bidirectional screws 31 extend along the length direction of the side beam 12. Specifically, combined with Figure 6 As shown, a module base 34 extending along the length direction of the side beam 12 is fixedly connected to the inner side wall of the side beam 12 , and the bidirectional lead screw 31 is rotatably connected to the module base 34 .

[0052] The stepper motor 32 is fixedly mounted on the inner wall of the side beam 12 , and its main shaft is connected to one end of the bidirectional lead screw 31 via a coupling; thus, the stepper motor 32 drives the bidirectional lead screw 31 to rotate.

[0053] like Figure 2As shown, the two bidirectional lead screws 31 are both threadedly connected with two nut sliders 33, wherein the two nut sliders 33 are respectively arranged on the two threaded sections of the bidirectional lead screw 31, and the nut sliders 33 can be displaced along the length direction of the module base 34. In other words, each bidirectional lead screw 31 is provided with two nut sliders 33, and the two nut sliders 33 are respectively arranged on the positive thread section and the negative thread section of the bidirectional lead screw 31, so that when the bidirectional lead screw 31 rotates, the two nut sliders 33 of the bidirectional lead screw 31 can move in opposite directions at the same time.

[0054] In this embodiment, the skylight structure further includes:

[0055] like Figure 3 As shown, the floating guide rail 7 includes two groups, which are fixed to the outside of the two side beams 12 of the window frame 1 by screws. The floating guide rail 7 is long and extends along the length direction of the side beam 12; Figure 9 As shown, the middle part of the upper wall of the floating guide rail 7 protrudes upward to form a protruding section 71. Specifically, both ends of the floating guide rail 7 have limiting end surfaces 72; the upper walls of the floating guide rail 7 on both sides of the protruding section 71 are horizontal guide surfaces 73; the connection between the guide surface 73 and the protruding section 71 is a smooth arc transition section to form a floating guide slope 74.

[0056] Combine Figure 9 As shown, the floating module 8 includes two guide wheels 81 respectively provided at the lower part of the two ends of the door panel 2, and two linear motion components 82 respectively provided at the lower part of the two ends of the door panel 2; It should be noted that two guide wheels 81 are provided at both ends of each door panel 2. Specifically:

[0057] like Figure 8 As shown, inverted U-shaped support feet 811 are fixedly installed at the bottom of both ends of the door panel 2, and the guide wheel 81 is rotatably installed in the support feet 811 through an axle pin so that the guide wheel 81 can roll freely; the guide wheel 81 is movably arranged on the guide rail, that is, the guide wheel 81 can roll on the upper wall of the floating guide rail 7 along the upper wall track of the floating guide rail 7.

[0058] The linear motion assembly 82 includes a vertically arranged slide rail fixedly mounted on the side wall of the nut slider 33 , and a slide seat slidably connected to the slide rail and displaceable along the height direction of the slide rail; wherein the slide seat is fixedly connected to the door panel 2 .

[0059] Specific: such as Figure 6 As shown, the slide rail includes a U-shaped mounting plate 821, which can be made of sheet metal. The two sides of the mounting plate 821 are folded inward to form two bent portions 8211, and the two bent portions 8211 are fixedly connected to vertical guide rail portions 8212. The side of the mounting plate 821 away from the guide rail portion 8212 is fixed to the nut slider 33.

[0060] The sliding seat includes a right-angle Z-shaped connecting plate 822, which can be made of sheet metal. The connecting plate 822 is fixedly connected to the side wall close to the guide rail part 8212 with two vertically arranged sliding parts 8221. The two sliding parts 8221 are respectively slidably connected to the two guide rail parts 8212 to vertically displace along the guide rail part 8212. The upper end of the connecting plate 822 is fixedly connected to the bottom wall of the door panel 2.

[0061] Through the above-mentioned arrangement, the gravity of the door panel 2 is concentrated on the guide wheel 81 at the lower part of the door panel 2, forcing it to roll close to the upper surface of the floating guide rail 7; when the door panel 2 is in the process of opening, the guide wheels 81 on the two door panels 2 roll on the two guide surfaces 73 respectively. At this time, the two door panels 2 move horizontally inside the outer panel of the adapted cabinet. Before the two door panels 2 are closed, the guide wheels 81 of the two door panels 2 are on the floating guide slope 74, and the two door panels 2 will float upward under the guidance of the slide rail and the slide seat until the guide wheel 81 is on the upper wall of the raised section 71 and stops floating. At this time, the convex surface 21 of the upper surface of the two door panels 2 is in the same plane with the outer surface of the outer panel of the cabinet. In other words, when the door panels 2 are closed, they can be flush with the outer surface of the outer panel of the cabinet, which is more beautiful.

[0062] In this embodiment, combined with Figure 4 and Figure 5 As shown, the skylight structure also includes a linkage mechanism 9; the linkage mechanism 9 includes two coaxially arranged transmission shafts 91; wherein the two transmission shafts 91 are both rotatably connected to the inner wall of the end beam 11 on the side away from the stepper motor 32; and the two transmission shafts 91 are spaced apart from each other at opposite ends.

[0063] The opposite ends of the two transmission shafts 91 are fixedly connected to the first bevel gears 92;

[0064] The two transmission shafts 91 are fixedly connected to the opposite ends thereof with a second bevel gear 93;

[0065] The ends of the two bidirectional lead screws 31 away from the stepping motor 32 are fixedly connected to third bevel gears 94 respectively meshing with the two second bevel gears 93;

[0066] A fourth bevel gear 95 is provided between opposite ends of the two transmission shafts 91 and is respectively engaged with the two first bevel gears 92 ; wherein the fourth bevel gear 95 is fixedly connected to a rotating shaft 96 rotatably connected to the end beam 11 .

[0067] Through the above-mentioned arrangement, the two transmission shafts 91 and the two bidirectional lead screws 31 form a closed-loop motion system. If the linkage mechanism 9 is not provided, the two door panels 2 will be controlled solely by the two stepper motors 32 for movement. In this way, once one of the stepper motors 32 loses step, the rotation angles of the two stepper motors 32 will be different, and the stepper motor 32 that moves ahead will overload and trip due to excessive load torque.

[0068] In this embodiment, since a linkage mechanism 9 is provided, the two bidirectional lead screws 31 can maintain synchronous rotation under the linkage of the bevel gears and the two transmission shafts 91, and the problem of one door panel 2 opening a large distance and the other door panel 2 opening a small distance due to the stepping motor 32 losing step will not occur.

[0069] In order to be able to manually open / close the door panel 2 when an electric failure occurs, in this embodiment, a fixing seat 97 is fixedly installed on the end beam 11; the rotating shaft 96 is rotatably connected to the fixing seat 97, and the end of the rotating shaft 96 away from the fourth bevel gear 95 passes through the end beam 11 and the fixing seat 97 and is fixedly connected to a manual operating shaft 98.

[0070] In order to facilitate the rotation of the manual operating shaft 98, in this embodiment, the manual operating shaft 98 is a hexagonal shaft, which is suitable for a hexagonal wrench.

[0071] In this way, when an electric failure occurs, the manual operating shaft 98 can be rotated with the help of a wrench, which can drive the rotating shaft 96 to rotate, and then drive the two transmission shafts 91 to rotate through the meshing fourth bevel gear 95 and the first bevel gear 92, and then drive the two bidirectional screws 31 to rotate through the meshing second bevel gear 93 and the third bevel gear 94, and then drive the nut slider 33 on the bidirectional screw 31 to move, thereby achieving the purpose of opening / closing the door panel 2.

[0072] It can be seen that the linkage mechanism 9 in this embodiment has two functions. First, it can form a closed-loop motion system between the two bidirectional screws 31 and other components to solve the problem of the door panel 2 opening / closing failure caused by the stepping motor 32 losing step; second, when the electric failure occurs, the door panel 2 can be manually opened / closed, avoiding the complicated disassembly work required for maintenance.

[0073] Implementation principle:

[0074] When the two door panels 2 need to be closed, the two nut sliders 33 are driven by the two stepping motors 32 to move in the direction of approaching each other, so that the two door panels 2 will move toward the middle and gradually close. During this process, the gravity of the door panel 2 is concentrated on the guide wheel 81 at the lower part of the door panel 2, forcing it to roll close to the upper surface of the floating guide rail 7. At this time, the two door panels 2 move horizontally inside the outer panel of the adapted cabinet. Before the two door panels 2 are closed, the guide wheels 81 of the two door panels 2 are on the floating guide slope 74, and the two door panels 2 will float upward under the guidance of the slide rail and the slide seat until the guide wheel 81 is on the upper wall of the raised section 71 and stops floating. At this time, the convex surface 21 of the upper surface of the two door panels 2 is in the same plane with the outer surface of the outer panel of the cabinet. In other words, when the door panel 2 is closed, it can be flush with the outer surface of the outer panel of the cabinet, which is more beautiful.

[0075] Similarly, when the door panels 2 need to be opened, it is only necessary to control the two stepping motors 32 to rotate in the reverse direction, and the two door panels 2 will move in opposite directions and eventually be retracted inside the cabinet.

[0076] Moreover, when the door panel 2 is closed, if there is rain, since the opposite ends of the door panel 2 are provided with an upper step 24 and a lower step 23, and a sealing strip is provided, when the door panel 2 is closed, the sealing strip is squeezed and compressed to seal the door gap between the two door panels 2, so that rainwater cannot leak from the door gap, and rainwater will only flow to the sides and tail of the door panel 2. The rainwater flowing to the sides of the door panel 2 will directly enter the guide groove 5, and the rainwater flowing to the tail of the door panel 2 will flow into the water stop groove 6, and then flow from the water stop groove 6 to the water collection groove 4, and finally be discharged from the outlet pipe 41 of the water collection groove 4, so as to achieve a waterproof effect.

[0077] The above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
