[0002] Skylights are holes set on the top of an object and closed with doors and windows. Skylights are widely used, such as skylights on building roofs, skylights on vehicle roofs, and skylights in drone storage cabinets. Skylights are divided into openable and non-openable types based on whether the doors and windows can be opened. Nowadays, openable and closed skylights are generally fully automatic.

[0003] At present, the fully automatic opening and closing structure commonly used in skylights is required to ensure that the skylight is flat after closing. The movement trajectory of the skylight when closing is to move horizontally first and then lift upward. Therefore, two sets of motion mechanisms are used to complete it. One of the motion mechanisms first moves the window sash horizontally to the bottom of the window, and then the other set of motion mechanisms realizes the upward movement.

[0004] The existing skylight opening and closing structure adopts two sets of motion mechanisms, and the complexity of the motion mechanisms makes the corresponding control also more complicated. Utility Model Content

[0043] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0044] First embodiment

[0045] Refer to 1 to Figure 4 The first embodiment of the utility model provides a sunroof opening and closing structure, including a blocking plate 7 and two closed structures, which are symmetrically arranged on both sides of the blocking plate 7. The closed structure includes a floating plate 21, a base frame 22 and a multi-link mechanism. Among them, the base frame 22 is a square frame, and the floating plate 21 is a flat plate.

[0046] Reference Figure 1 and Figure 2 , Figure 1 and Figure 2The flat plate-mounted object formed by the dotted line (dashed line) in the figure represents the skylight 1, wherein a hole is provided in the middle of the skylight 1, the hole is the window of the skylight, and the flat plate near the hole is the top wall of the skylight. The base frame 22 is suitable for sliding connection to the top wall of the skylight 1, and the base frame 22 can slide between a first position 100 and a second position 200. The connecting line between the first position 100 and the second position 200 is a straight line parallel to the base frame 22, and the first position 100 is closer to the skylight 1 than the second position 200. The blocking plate 7 is provided on the sliding path of the base frame 22. The multi-link mechanism is movably connected between the floating plate 21 and the base frame 22.

[0047] Combination Figure 1 and Figure 2 In this embodiment, the base frame 22 is located below the skylight 1, and the base frame 22 is slidably connected to the top wall of the skylight through a transmission assembly. The floating plate 21 is located above the base frame 22, the base frame 22 and the floating plate 21 are parallel, and the blocking plate 7 is vertically arranged, and the blocking plate 7 is arranged at the first position 100. Figures 3 to 6 As shown, the multi-link mechanism includes a plurality of mutually parallel supporting links 23, the first end of the supporting link 23 is rotatably connected to the floating plate 21, and the second end of the supporting link 23 is rotatably connected to the base frame 22, so that the floating plate 21 can swing relative to the base frame 22. The rotation principle of the structure formed by the base frame 22, the floating plate 21 and the plurality of supporting links 23 is the same as the rotation principle of the planar four-link mechanism.

[0048] Reference Figure 1 When the skylight 1 is in the open state, the base frame 22 is located at the second position 200, and the floating plate 21 is located away from the skylight (that is, at the second position). The floating plate 21 can be closely attached to the base frame 22. In summary, the floating plate 21 is separated from the skylight 1, so that the skylight 1 is in the open state;

[0049] Reference Figure 2 When the sunroof 1 is switched to the closed state, the base frame 22 slides toward the first position 100 so that the floating plate 21 first contacts the blocking plate 7 and then slides upward along the surface of the blocking plate 7 to gradually close the sunroof 1.

[0050] Until the base frame 22 moves to the first position, at this time, the base frame abuts against the blocking plate 7, and the floating plate 21 just enters the skylight, so that the skylight 1 is completely closed.

[0051] Reference Figure 1 , Figure 2 and Figure 3 The two floating plates 21 move from their respective second positions 200 to their respective first positions 100 , so that the two floating plates 21 jointly close the skylight 1 . That is, in this embodiment, the skylight 1 is completely closed by the two floating plates 21 .

[0052] Reference Figure 1-Figure 4, the working process of this embodiment is described in detail: when in the closed state, the base frame 22 is located at the first position 100, the floating plate 21 is located directly above the base frame 22, and the floating plate 21 closes the skylight 1. At this time, the supporting link 23 is perpendicular to the base frame 22 and the floating plate 21. Of course, in other embodiments, the supporting link 23 does not need to be perpendicular to the floating plate 21.

[0053] When the sunroof 1 switches from a closed state to an open state, the transmission assembly drives the base frame 22 to slide in a direction away from the sunroof 1, that is, the base frame 22 slides toward the second position 200, pulling the support link 23 to make the first end of the support link 23 rotate downward around its second end, and the floating plate 21 moves downward under the drive of its gravity and the support link 23, that is, the floating plate 21 gradually approaches the base frame 22 and simultaneously separates from the sunroof 1, as the base frame 22 continues to slide toward the second position 200, the base frame 22 drives the floating plate 21 and the support link 23 away from the sunroof 1, until the base frame 22 reaches the second position 200, the floating plate 21 is completely separated from the sunroof 1, and at this time, the sunroof 1 is in an open state.

[0054] When the sunroof 1 switches from opening to closing, the base frame 22 slides toward the first position 100, and the floating plate 21 and the supporting link 23 slide toward the first position 100 together with the base frame 22. When the base frame 22 moves a certain distance and has not reached the first position 100 at this time, since the edge of the floating plate 21 is closer to the first position 100 than the edge of the base frame 22, the floating plate 21 first contacts the blocking plate 7 at the first position 100. At this time, the floating plate 21 is stopped by the blocking plate 7, and the floating plate 21 and the supporting link 23 cannot slide with the base frame 22 anymore. As the base frame 22 continues to slide toward the first position 100, since the first end of the support link 23 is hinged to the floating plate 21, the floating plate 21 rotates with the second end of the support link 23 as the center, so that the floating plate 21 swings relative to the base frame 22 in a direction away from the base frame 22, and then the support link 23 drives the floating plate 21 to move upward along the surface of the blocking plate 7 until the floating plate 21 enters the window of the skylight. In other words, during this process, the floating plate 21 only moves upward. When the base frame 22 moves to the first position 100, the floating plate 21 just closes the skylight 1. In this embodiment, when closing the skylight 1, the support link 23 is perpendicular to the floating plate 21 and the base frame 22.

[0055] Therefore, it can be seen from the above working process that the present embodiment uses the supporting connecting rod 23, the floating plate 21 and the base frame 22 to form a parallelogram structure, and the movement trajectory of the closed skylight 1 of the floating plate 21 is divided into the following two states: first, when the base frame 22 starts to slide from the second position 200, the floating plate 21 slides synchronously with the base frame 22, and the two move in the same direction; second, the floating plate 21 is stopped by the blocking plate 7, and then the movement directions of the floating plate 21 and the base frame 22 are perpendicular. Compared with the prior art that uses two sets of transmission mechanisms, the present embodiment only uses one set of transmission components, and the transmission component only needs to simultaneously drive the base frames 22 of the two closed structures to move toward or away from each other.

[0056] Reference Figure 4 and 5 In this embodiment, the sunroof opening and closing structure further includes a transmission assembly, which includes a slide rail 4 assembly and a power assembly. The slide rail 4 assembly includes a track and a slider that are slidably connected to each other, the track is fixedly connected to the sunroof 1, and the slider is fixedly connected to the base frame 22. The blocking plate 7 is fixedly connected to the track. The power assembly drives the slider to move relative to the slide rail 4.

[0057] In order to realize the synchronous movement of the floating plates 21 in the two groups of closed structures, the power assembly includes a synchronous belt 34, a driving wheel 31, a driven wheel 32 and a tensioning wheel 33. The driven wheel 32 and the tensioning wheel 33 are respectively arranged at the second position 200 of the slide rails 4 of the two closed structures, and the first position 100 of the two closed structures coincides with the position of the blocking plate 7. The driving wheel 31 is arranged between the driven wheel 32 and the tensioning wheel 33. The synchronous belt 34 is tensioned on the driving wheel 31, the driven wheel 32 and the tensioning wheel 33 to form a belt drive. The driving wheel 31, the driven wheel 32 and the tensioning wheel 33 are respectively installed on the track.

[0058] More specifically, each closed structure further includes a connecting piece 35. In a closed structure, the connecting piece 35 is respectively fixedly connected to the base frame 22 and the synchronous belt 34, so that the base frame 22 can move synchronously with the synchronous belt 34. In this embodiment, referring to the accompanying drawings, the driving wheel 31 and the driven wheel 32 divide the pulley into a first sub-belt and a second sub-belt, one end of the first sub-belt and one end of the second sub-belt coincide at a point on the outer edge of the driven wheel 32, and the other end of the first sub-belt and the other end of the second sub-belt coincide at a point on the outer edge of the driving wheel 31.

[0059] The base frame 22 of one closed structure is connected to the first sub-belt through the connecting piece 35; the base frame 22 of the other closed structure is connected to the second sub-belt through the connecting piece 35. Since the movement directions of the first sub-belt and the second sub-belt are opposite, when the driving wheel 31 rotates, the belt rotates accordingly, driving the base frames 22 of the two closed structures to move towards or away from each other.

[0060] Reference Figure 5 and Figure 6 The sunroof opening and closing structure further includes at least one set of sensing components, which include a sensing member 93, an opening sensor 91, and a closing sensor 92. The sensing member 93 is disposed on the base frame 22, and the closing sensor 92 is disposed at a first position 100, so that when the sensing member 93 reaches the first position 100, it can be sensed by the closing sensor 92. Similarly, the opening sensor 91 is disposed at a second position 200, so that when the sensing member 93 reaches the second position 200, it can be sensed by the opening sensor 91. The sensing component is used to determine the movement position of the base frame 22 to determine the position of the base frame 22.

[0061] In this embodiment, both the opening sensor 91 and the closing sensor 92 have a groove penetrating along the sliding direction of the base frame 22, and the sensing member 93 is disposed on a side of the base frame 22 close to the first position 100. When the base frame 22 moves to the first position 100, the sensing member 93 enters the groove of the closing sensor 92 and is sensed by the sensing unit of the closing sensor 92. When the base frame 22 moves to the second position 200, the sensing member 93 enters the groove of the opening sensor 91 and is sensed by the sensing unit of the opening sensor 91.

[0062] Reference Figure 5 In this embodiment, a roller 8 is provided on the side of the floating plate 21 near the first position 100. The roller 8 can roll on the blocking plate 7, and the roller 8 is used to guide the floating plate 21 to move upward on the surface of the blocking plate 7, thereby closing the skylight 1. Specifically, when the floating plate 21 moves to the first position 100, the roller 8 contacts the blocking plate 7, and the base frame 22 continues to move toward the first position 100. When the floating plate 21 moves upward, the roller 8 also moves upward. At this time, the friction between the floating plate 21 and the blocking plate 7 is reduced, and the floating plate 21 moves upward more smoothly.

[0063] In this embodiment, an elastic buffer pad 71 is provided on the side of the blocking plate 7 close to the base frame 22. The buffer pad 71 is located at the lower side of the blocking plate 7. The buffer pad 71 protrudes from the blocking plate 7. When the base frame 22 moves to the first position 100, the buffer pad 71 can be squeezed and deformed by the base frame 22. When the base frame 22 is located at the first position 100, the buffer pad 71 is gradually squeezed by the base frame 22 from the beginning of contacting the base frame 22. The buffer pad 71 plays a buffering role to reduce the collision between the base frame 22 and the blocking plate 7.

[0064] Reference Figure 5 and Figure 6In this embodiment, the closed structure further includes a tension spring 5, one end of which is connected to the floating plate 21, and the other end is connected to the base frame 22. The tension of the tension spring 5 makes the floating plate 21 tend to move closer to the base frame 22. With the help of the tension spring 5, when the skylight 1 is opened, once the base frame 22 starts to move, the tension of the tension spring 5 drives the floating plate 21 to move quickly toward the base frame 22. In the initial opening state, the skylight 1 can have a certain opening, so that the opening speed of the skylight 1 is increased. Moreover, during the movement, the tension spring 5 can stably ensure that the floating plate 21 is attached to the base frame 22, and the floating plate 21 and the base frame 22 will not shake at will, thereby reducing the phenomenon of collision and noise.

[0065] If there is no tension spring 5 , it is necessary to manually confirm and maintain that the edge of the floating plate 21 adjacent to the first position 100 is closer to the blocking plate 7 than the edge of the base frame 22 adjacent to the first position 100 .

[0066] Reference Figure 5 In this embodiment, the closed structure also includes a limit plate 6, which is arranged at the second position 200 and fixed on the track. The limit plate 6 is used to prevent the connecting plate from crossing the second position 200 during the movement toward the second position 200, thereby limiting the maximum distance that the base frame 22 slides toward the second position 200.

[0067] Reference Figure 6 In this embodiment, each supporting link 23 extends along its length direction so that the supporting link 23 is plate-shaped, the length direction of the supporting link 23 is perpendicular to the sliding direction of the base frame 22, and the length direction of the supporting link 23 is also perpendicular to the up-down direction, or in other words, the length direction of the supporting link 23 is parallel to its own rotation axis, and the two ends of the supporting link 23 in the width direction are respectively rotatably connected to the floating plate 21 and the base frame 22. A plurality of through holes are provided on the supporting link 23 along its length direction to form a hollow structure to reduce weight.

[0068] Furthermore, since the floating plate 21 is in the shape of a flat plate, the two ends of the plate-shaped supporting link 23 in the length direction are respectively located on the opposite side walls of the floating plate 21, thereby ensuring that the opposite sides of the floating plate 21 will not shake during the swinging process of the floating plate 21.

[0069] In other embodiments, each supporting link 23 is rod-shaped.

[0070] Second embodiment

[0071] Reference Figure 4 The second embodiment of the utility model provides a sunroof opening and closing structure, which is different from the first embodiment in that the sunroof opening and closing structure includes a blocking plate 7 and a group of closed structures.

[0072] In this embodiment, there is only one floating plate 21 , and the shape of the floating plate 21 is the same as that of the skylight 1 , so that one floating plate 21 is sufficient to close the skylight 1 .

[0073] In this embodiment, the power assembly is also different from that in the first embodiment. Although the power assembly of this embodiment can also drive the slider to move relative to the slide rail 4.

[0074] However, in detail, the slide rail 4 assembly in this embodiment can be a screw nut mechanism, the screw is the track in the slide rail 4 assembly, the nut is the slider in the slide rail 4 assembly, and the corresponding power assembly is the motor that drives the screw to rotate. Of course, the transmission assembly can also be an electric slide or similar device that has both a power source and a slide rail 4. The transmission assembly can also be composed of a cylinder as a power assembly and a slide rail 4 as a slide rail 4 assembly.

[0075] Third embodiment

[0076] The third embodiment of the utility model provides a skylight opening and closing structure, which is different from the first embodiment in that the supporting connecting rod in this embodiment is rod-shaped, and multiple supporting connecting rods are divided into two rows, and the two rows of supporting connecting rods are respectively rotatably connected to the opposite side walls of the floating plate.

[0077] Fourth embodiment

[0078] The fourth embodiment of the utility model also provides a drone docking cabinet, comprising a cabinet body and any one of the above-mentioned skylight opening and closing structures, wherein the top wall of the cabinet body is provided with a window, the top wall of the cabinet body constitutes the top wall of the skylight, the window provided on the top wall of the cabinet body constitutes the window of the skylight, and the skylight opening and closing structure is installed on the cabinet body to open and close the skylight.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
