Description

Technical Field

[0001] The utility model belongs to the technical field of two-way synchronous door opening of a rotor hangar, and specifically relates to a six-axis rotor hangar two-way synchronous door opening mechanism. Background Technique

[0002] With the wide application of unmanned aerial vehicles (UAVs) in the inspection industry, UAVs need to frequently enter and exit the hangar for charging and storage. In order to better store and prevent sundries from entering the hangar, opening and closing doors are usually set at the hangar entrance, and the opening and closing doors are divided into single-opening doors and double-opening doors.

[0003] The existing single-opening door panel has a relatively large volume for a single panel, often has a large space limitation when opening, and the opening efficiency is slow, affecting the entry and exit of UAVs. Therefore, the double-opening door design shows better advantages compared with the single-opening door design. However, the double-opening door design requires the two door panels to be opened and closed synchronously to ensure the opening and closing speed and good sealing effect. The existing technology generally uses two synchronous motors controlled by a controller. However, this design structure is relatively complex, and the controller is prone to problems such as being not debugged well or malfunctioning, which will affect the normal opening or closing of the double-opening door. For this reason, the inventor has developed a six-axis rotor hangar two-way synchronous door opening mechanism, hoping to solve the above-mentioned technical problems. Content of the Utility Model

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0024] like Figures 1 to 6As shown in the figure, a two-way synchronous door opening mechanism for a 6-axis rotor hangar includes a hangar main body 1. A transmission mechanism is provided at the lower end of the opening of the hangar main body 1. The transmission mechanism is used to synchronously transmit power. The transmission mechanism includes push-pull rods 11. There are two push-pull rods 11. One inner end of each push-pull rod 11 is fixedly connected with a rack slide rod 16. Transmission racks 14 are fixedly connected to the inner sides of the rack slide rods 16. And follower racks 9 are fixedly connected to the sides of the outer ends of the push-pull rods 11.

[0025] In this setting, the utility model adopts a mechanical transmission method to ensure that the double doors are always in a synchronous opening and closing state. The structure is relatively simple and effective, reducing the probability of failure. At the same time, a single power source is adopted, eliminating the step of debugging the synchronous controller, making the structure work more stably and efficiently.

[0026] As Figures 1 to 6 shown, in the specific implementation, a protective box 4 is fixedly connected to the upper surface of the bottom of the opening of the hangar main body 1. Through holes are opened at both ends of the protective box 4. The through holes correspond to the outer ends of the push-pull rods 11 and are movably sleeved with them. And support feet 3 are fixedly connected to the four corners at the lower end of the hangar main body 1.

[0027] In this setting, the function of the protective box 4 is to protect the internal mechanical components and at the same time play a role in beautifying the appearance.

[0028] As Figures 1 to 6 shown, in the specific implementation, a semi-card angle 6 and a stable card angle 10 are arranged inside the protective box 4. The lower ends of the semi-card angle 6 and the stable card angle 10 are fixedly connected to the upper surface of the bottom plate of the hangar main body 1. The semi-card angle 6 corresponds to the outer end of the push-pull rod 11 and is movably clamped with it. And the stable card angle 10 corresponds to the rod body of the push-pull rod 11 and is movably sleeved with it.

[0029] In this setting, the function of the semi-card angle 6 is to ensure the close meshing of the follower rack 9 and the follower gear 8, while the function of the stable card angle 10 is to limit the push-pull rod 11 to prevent its position from shifting.

[0030] As Figures 1 to 6 shown, in the specific implementation, a fixed box 12 is arranged at the central position inside the protective box 4. The lower end of the fixed box 12 is fixedly connected to the upper surface of the bottom plate of the hangar main body 1. A transmission gear 15 is movably installed inside the fixed box 12. The transmission gear 15 corresponds to the transmission rack 14 and meshes with it. And the internal channel of the fixed box 12 corresponds to the rack slide rod 16 and is slidably sleeved with it.

[0031] In this setting, the power motor 17 rotates and drives the transmission rack 14 and the rack slide rod 16 to slide through the transmission gear 15, and the push-pull rod 11 is pushed or pulled by the rack slide rod 16 to extend outward or contract inward.

[0032] As Figures 1 to 6 shown, in the specific implementation, a motor box 5 is fixedly connected to the lower surface of the bottom plate of the hangar main body 1, a power motor 17 is fixedly installed inside the motor box 5, and the transmission shaft at the upper end of the power motor 17 penetrates through the hangar main body 1 and corresponds to the transmission shaft rod 13 fixedly connected to the center of the transmission gear 15, and is fixedly connected thereto.

[0033] In this setting, when using and controlling this device, first start the power motor 17. The power motor 17 rotates and drives the transmission rack 14 and the rack slide rod 16 to slide through the transmission gear 15.

[0034] As Figures 1 to 6 shown, in the specific implementation, follower gears 8 are movably installed inside both ends of the protection box 4. The upper end of the follower shaft rod 7 fixedly connected to the center of the follower gear 8 is fixedly installed with a double-opening door plate 2, and the shaft rod at the upper end of the double-opening door plate 2 is movably connected to the top plate of the hangar main body 1.

[0035] In this setting, when using and controlling this device, first start the power motor 17. The power motor 17 rotates and drives the transmission rack 14 and the rack slide rod 16 to slide through the transmission gear 15. The push-pull rod 11 is pushed or pulled by the rack slide rod 16 to extend outward or contract inward; when the push-pull rod 11 extends outward, the follower gear 8 is driven to rotate through the follower rack 9, and the double-opening door plate 2 is driven to close through the follower shaft rod 7. Conversely, the double-opening door plate 2 is driven to open.

[0036] As Figures 1 to 6 shown, in the specific implementation, a spring slide rail 18 is fixedly connected to the inner bottom of the hangar main body 1. A spring 22 is sleeved inside the spring slide rail 18, and a slider 23 is slidably sleeved inside the spring slide rail 18. The upper end of the slider 23 is fixedly connected to a parking platform 20. The outer two corners of the parking platform 20 are chamfered, and pulleys 21 are fixedly installed at the chamfered corners. The pulleys 21 correspond to the inner side surface of the double-opening door plate 2, and platform slide rails 19 are movably clamped on both sides of the parking platform 20. The platform slide rails 19 are fixedly connected to the inner side wall of the hangar main body 1.

[0037] In this setting, the parking platform 20 is released and extended when the double-opening door plate 2 is opened, facilitating the landing action of the drone. When the double-opening door plate 2 is closed, the outer end corner of the parking platform 20 is squeezed, causing it to retract, and together with the drone, it is stored inside the hangar main body 1.

[0038] The implementation principle of a two-way synchronous door opening mechanism for a 6-axis rotor hangar in this embodiment is as follows:

[0039] The utility model ensures that the double doors are always in a synchronous opening and closing state by adopting a mechanical transmission method. The structure is relatively simple and effective, reducing the probability of failures. At the same time, a single power source is adopted, eliminating the step of debugging the synchronous controller, making the structure work more stably and efficiently;

[0040] When using and controlling this device, first start the power motor 17. The power motor 17 rotates and drives the transmission rack 14 and the rack slide rod 16 to slide through the transmission gear 15, and the push-pull rod 11 is pushed or pulled to extend outward or contract inward through the rack slide rod 16; when the push-pull rod 11 extends outward, it drives the follower gear 8 to rotate through the follower rack 9, and drives the double door panel 2 to close through the follower shaft rod 7. On the contrary, it drives the double door panel 2 to open; the function of the semi-locking angle 6 is to ensure the close meshing of the follower rack 9 and the follower gear 8, and the function of the stable locking angle 10 is to limit the push-pull rod 11 to prevent its position from shifting; and the function of the fixed box 12 is to limit the two rack slide rods 16, so that the transmission rack 14 and the transmission gear 15 are closely meshed; among them, the parking platform 20 is released and extended when the double door panel 2 is opened, facilitating the landing action of the drone. When the double door panel 2 is closed, the outer end corner of the parking platform 20 is squeezed, causing it to retract, and the drone is stored in the hangar main body 1 together.
