[0026] Please refer to Figure 1 , the embodiment of the present utility model provides an opening and closing mechanism for a split cover, which is applied to a split cover, that is, the cover includes two sliding covers 3 on both sides that can be opened separately, such as the cover on the top of the unmanned aerial vehicle cockpit of an unmanned aerial vehicle command vehicle in this embodiment. It can be understood that in some other embodiments, the opening and closing mechanism of the split cover can also be applicable to the covers of other various devices and equipment.

[0027] Please refer to Figure 2, the opening and closing mechanism of the split cover includes two opening and closing components, which are respectively arranged at both ends of the cover, and each opening and closing component is connected to the two side sliding covers 3 at one end of the cover. Each opening and closing component mainly includes a lower guide rail 6, a lower rack 10, an upper rack 9, a gear 11 and an upper guide rail 7.

[0028] The upper guide rail 7 is arranged parallel to the lower guide rail 6, and here the upper rack 9 and the lower rack 10 are arranged opposite to each other vertically. Generally, during actual installation, both the upper guide rail 7 and the lower guide rail 6 are arranged horizontally.

[0029] The lower rack 10 is slidably connected to the lower guide rail 6, the upper rack 9 is slidably connected to the upper guide rail 7, the gear 11 is arranged between the upper rack 9 and the lower rack 10, and the gear 11 meshes with the upper rack 9 and the lower rack 10. The two opening and closing components can be respectively arranged at both ends of the cover, and the upper rack 9 and the lower rack 10 of each opening and closing component are used to connect the two side sliding covers 3 respectively. The upper rack 9 and the lower rack 10 are both arranged along the opening and closing direction of the cover.

[0030] Generally, the two side sliding covers 3 of the cover are located on the same plane and open and close on the same plane. In order to respectively install the two side sliding covers 3 on the lower rack 10 and the upper rack 9, each opening and closing component further includes a lower bracket 4 and an upper bracket 5. The lower rack 10 is connected to the lower bracket 4, the lower rack 10 is installed on the outside of the lower bracket 4, the bottom of the lower bracket 4 is slidably connected to the lower guide rail 6, and the lower rack 10 can be connected to one side sliding cover 3 through the lower bracket 4. The upper rack 9 is connected to the upper bracket 5, the upper rack 9 is installed at the bottom of the upper bracket 5, the outside of the upper bracket 5 is slidably connected to the upper guide rail 7, and the upper gear 11 is connected to the other side sliding cover 3 through the upper bracket 5, so that the two side sliding covers 3 are arranged flush.

[0031] More specifically, a plurality of lower sliding blocks 8 are provided at the bottom of the lower bracket 4, and the lower guide rail 6 is embedded at the bottom of each lower sliding block 8, so that each lower sliding block 8 can slide along the lower guide rail 6; a plurality of side sliding blocks 12 are provided on the outside of the upper bracket 5, and the upper guide rail 7 is embedded in each side sliding block 12, so that each side sliding block 12 can slide along the upper guide rail 7.

[0032] Moreover, due to the height difference between the upper rack 9 and the lower rack 10, the lower bracket 4 can be set as a triangular bracket. The bottom of the lower bracket 4 is arranged parallel to and slidably connected to the lower guide rail 6, and the upper part of the lower bracket 4 is arranged obliquely. When the two side sliding covers 3 are closed, the lower bracket 4 moves to the bottom of the side sliding cover 3 that is not connected to it, and will not affect the movement of this side sliding cover 3.

[0033] In order to drive the rotation of the gear 11 and drive the two side sliding covers 3 to automatically open and close, each opening and closing assembly further includes a power source, and the power source is connected to the gear 11 to drive the rotation of the gear 11. In this embodiment, the power source includes a motor 1 and a speed reducer 2 connected to the motor 1, and the main shaft of the speed reducer 2 is connected to the gear 11. In order to synchronously drive the two side sliding covers 3 to open and close by the two opening and closing assemblies, the rotation directions of the main shafts of the speed reducers of the two power sources of the two opening and closing assemblies are opposite and the rotation speeds are the same.

[0034] Considering that the cover generally has two states of being fully opened and fully closed during operation, limit blocks are provided on both the lower guide rail 6 and the upper guide rail 7 to limit the sliding strokes of the upper rack 9 and the lower rack 10. Since the two side sliding covers 3 generally move symmetrically, the limit blocks are arranged at predetermined positions so that the sliding strokes of the upper rack 9 and the lower rack 10 are the same.

[0035] When the opening and closing mechanism of the split cover is actually installed, the two opening and closing assemblies are respectively arranged at both ends of the cover, and the two opening and closing assemblies are symmetrically arranged. The lower guide rail 6 of each opening and closing assembly is installed on a horizontal installation surface, the upper guide rail 7 is installed on a vertical installation surface, and the two side sliding covers 3 are respectively fixedly connected to the upper rack 9 and the lower rack 10, and then the installation can be completed. After that, only by controlling the two power sources to drive the two gears 11 at the same rotation speed and opposite rotation directions, the two side sliding covers 3 can be controlled to open and close.

[0036] In some embodiments, for the sake of beautiful and neat appearance, the two opening and closing assemblies can be respectively arranged at both ends of the back of the cover, and the two opening and closing assemblies can be hidden inside the drone cockpit, which can also play a certain protective role for the two opening and closing assemblies.
