Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a quick locking device for the skin of an unmanned aerial vehicle. Background Technique

[0002] With the rapid development of unmanned aerial vehicle technology, unmanned aerial vehicles are increasingly widely used in various fields. Today, in the pursuit of high performance and high convenience, unmanned aerial vehicles have gradually changed from the initial overall structure to a modular structure. As an important part of an unmanned aerial vehicle, the skin of the unmanned aerial vehicle is also the key to the unmanned aerial vehicle module. The stability and reliability of its connection structure have an important impact on the overall performance of the unmanned aerial vehicle. Traditional connection structures of the skin of unmanned aerial vehicles often have problems such as inconvenient carrying, insufficient strength, cumbersome assembly, uncontrollable locking force, poor sealing performance, and poor waterproof performance, and cannot meet the requirements of unmanned aerial vehicles for rapid takeoff and high-load operation in complex environments. Content of the Utility Model

[0003] The purpose of the utility model is to provide a quick locking device for the skin of an unmanned aerial vehicle to solve the problems put forward in the above background technique.

[0004] The above object of the utility model is achieved by the following technical solutions:

[0005] A quick locking device for the skin of an unmanned aerial vehicle, characterized in that: it includes an upper skin, a lower skin, an upper buffer pad, a lower buffer pad, a rib plate, a gear, a rack, a one-way bearing, and a base. The upper buffer pad and the lower buffer pad are respectively bonded to the upper skin and the lower skin by a bonding method, and can increase the sealing performance of the skin under the action of the internal gear. The rack is connected to the reinforcing rib inside the upper skin by bolts, and its lower part passes through a rectangular groove connected to the reinforcing rib of the lower skin. The gear and the rack are meshed with each other for transmission. One end of the gear passes through the one-way bearing and is connected to the knob by a thread, and one end is connected to the upper end of the base by a clearance fit. The base is fixedly connected to the ear plate by bolts, and the ear plate is connected to the rib plate by welding.

[0006] Furthermore, the upper skin and the lower skin are made of fiberglass and are coated on the surface of the reinforcing rib in a bonded form.

[0007] Furthermore, one end of the rack is connected to the reinforcing rib connected to the upper skin by bolts, and one end passes through a rectangular groove connected to the reinforcing rib of the lower skin.

[0008] Furthermore, the inner ring of the one-way bearing contains a keyway and is matched with the key protruding from the surface of the upper gear. So that the gear can move up and down axially, and the outer ring is connected to the reinforcing rib inside the lower skin by an interference fit.

[0009] Furthermore, the lower gear shaft and the upper part of the base are of a hollow ring structure, and a spring is installed inside.

[0010] Furthermore, the rib plate is made of lightweight aluminum alloy material and is installed in the middle part of the upper and lower skins. The ear plate protruding from one side close to the skin is connected to the rib plate by welding.

[0011] Compared with the existing utility model, the beneficial effects of the present utility model are as follows:

[0012] (1) The body is divided into three parts: the upper skin, the lower skin, and the rib plate, which can be modularly connected and has the characteristic of being convenient to carry.

[0013] (2) The connection mode between the upper skin and the lower skin is carried out by means of gear-rack meshing transmission, making the connection between the skins more firm. Under the action of the one-way bearing, the gear can rotate single-directionally to drive the rack to move in one direction, making the skin connection have the characteristics of convenient and fast connection.

[0014] (3) Under the action of the lower spring, the gear can quickly withdraw from the meshing with the rack, so as to achieve the purpose of quick disassembly.

[0015] (4) The combined action of the gear and the rubber strip can not only adjust the locking force of the skin, but also increase the sealing performance of the skin connection, making it have a certain waterproof function. Description of the Drawings

Specific Embodiment

[0022] Such as Figures 1 - 5As shown, the skin connection quick-release device includes an upper skin 1, a lower skin 2, a rib plate 3, an upper buffer pad 4, a lower buffer pad 5, a gear 6, a rack 7, and a base 8. The upper buffer pad 4 and the lower buffer pad 5 are adhesively attached to the lower ends of the upper skin 1 and the lower skin 2 respectively by bonding. The upper and lower buffer pads can play a role in waterproofing and increasing the sealing performance during the docking process of the upper and lower skins. One end of the rack 7 is connected to the stiffener 11 of the upper skin 1 by bolts, and the other end is limited by a rectangular groove 22 connected to the stiffener of the lower skin 2. The gear 6 meshes with the rack 7 for transmission.

[0023] As Figure 1 shown, the skin is wrapped around the outer surface of the stiffener in a bonded form; the rib plate 3 is made of a lighter aluminum alloy material, and a rectangular ear plate 31 is welded on one side of the rib plate and installed on the base 8 by bolts.

[0024] As Figure 2 shown, one end of the gear 6 passes through a one-way bearing 9 and is connected to a knob 63 by threads; one end is fitted with the upper end of the base 8 by clearance fit. The inner part of its lower gear shaft 62 and the upper end of the base 8 are both hollow structures, and a spring 82 is installed inside. The function of the spring enables the gear to move within a certain range in the axial direction, so as to quickly withdraw from the engagement with the rack and achieve the purpose of quick release.

[0025] As Figure 4 shown, the inner ring of the one-way bearing 9 contains a rectangular groove and is fitted with a rectangular flat key protruding from the outer surface of the upper gear shaft 61. When the knob 63 is twisted, due to the limitation of the one-way bearing 9, the gear 6 can only rotate unidirectionally, so that the gear 6 rotates to a certain position and locks itself to prevent the upper and lower skins from separating.
