Description

Technical Field

[0001] This utility model relates to the field of UAV CANbus wiring harness technology, specifically an integrated UAV CANbus wiring harness. Background Technology

[0002] With the rapid development of drone technology, it has been widely used in agriculture, surveying and mapping, image acquisition and other fields.

[0003] However, there are some problems with the existing drone wiring harness layout. A certain length of redundant wiring harness needs to be reserved during the movement of drone moving parts to avoid stretching and breakage. However, the redundant wiring harness is prone to loosening, tangling or friction with other parts when not in operation. Especially during the folding or unfolding of the arms of multi-rotor drones, wiring harness tangling may cause signal transmission interruption or mechanical jamming.

[0004] In addition, the high-frequency vibrations during drone flight can cause stress concentration at the connection between the wiring harness and the fixed structure. Long-term use can easily lead to wear of the wiring harness insulation layer and breakage of the wires. Especially in traditional rigid fixing methods, the vibration energy is directly transmitted to the root of the wiring harness, which will aggravate fatigue damage.

[0005] Therefore, this utility model provides an integrated UAV CANbus harness to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides an integrated CANbus harness for unmanned aerial vehicles (UAVs), aiming to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: an integrated UAV CANbus harness, comprising a stress-dispersing fixing seat, a support block, a connecting block, a fixing lug, and a set bolt. The stress-dispersing fixing seat is internally equipped with a harness storage mechanism. The harness storage mechanism includes a central shaft, a coil spring, a winding drum, a harness, an upper guide wheel, a lower guide wheel, and a harness fixing clamp. The outer side of the central shaft is connected to the coil spring, and the other end of the coil spring is connected to the winding drum. The winding drum has an inlet and an outlet facing each other.

[0010] As a preferred technical solution of this application, the inside of the winding drum is connected to the wire harness, and an upper guide wheel and a lower guide wheel are installed on the outside of the wire harness. The upper guide wheel and the lower guide wheel are distributed up and down along the wire harness, and a wire harness fixing clip is installed on the surface of the wire harness.

[0011] As a preferred technical solution of this application, the stress dispersion fixing seat includes a fixing seat frame body, a rectangular connecting seat, a stress dispersion connecting arm, a wire harness fixing groove, and an elastic pad. The rectangular connecting seats are connected to both sides of the fixing seat frame body, and the stress dispersion connecting arm is installed on one side of the rectangular connecting seat.

[0012] As a preferred technical solution of this application, a wire harness fixing groove is installed on the other side of the rectangular connector, and an arc-shaped groove is opened on the surface of the wire harness fixing groove, and an elastic pad is connected inside the arc-shaped groove.

[0013] As a preferred technical solution of this application, there are two connecting blocks, and one end of each connecting block is connected to the upper guide wheel and the lower guide wheel, respectively.

[0014] As a preferred technical solution of this application, there are two support blocks, one end of which is connected to a side plate, and the bottom surface of the wire harness fixing clip is connected to the side plate.

[0015] As a preferred technical solution of this application, the stress dispersion fixing seat has fixing lugs distributed circumferentially at its bottom, and set bolts are installed inside the fixing lugs. The stress dispersion fixing seat is connected to the UAV through the set bolts.

[0016] (III) Beneficial Effects

[0017] The installed wire harness storage mechanism can wrap up redundant wire harnesses in the drone, preventing them from affecting the normal operation of the drone.

[0018] By combining the winding drum and the coil spring, the redundant wire harness can be automatically contracted and released. When the movable end of the UAV is unfolded, the wire harness is released under tension and kept taut. When the movable end is reset, the coil spring drives the winding drum to neatly wind the redundant wire harness, which solves the problem of loose and tangled redundant wire harnesses in traditional systems and reduces the risk of failure caused by wire harness interference.

[0019] The arc-shaped stress-dispersing connecting arm of the stress-dispersing fixing seat is made of spring steel, which can absorb the vibration energy of the drone during flight through elastic deformation. The silicone elastic pad in the wire harness fixing groove fits tightly against the wire harness, reducing the local stress caused by rigid contact. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides an integrated drone CANbus harness, including a stress-dispersing fixing seat 1 and a harness storage mechanism 4. The stress-dispersing fixing seat 1 serves as the foundation of the device. Its fixing seat frame body 101 is made of high-strength aluminum alloy. Rectangular connecting seats 102 are bolted to both sides. One side of the rectangular connecting seat 102 has an integrally formed stress-dispersing connecting arm 103 made of spring steel with an arc-shaped structure. The other side is connected to a harness fixing groove 104 through a support block 2. An elastic pad 105 is embedded in the groove. The elastic pad 105 is made of silicone with an anti-slip texture on the surface. Four fixing lugs 5 are distributed circumferentially at the bottom of the stress-dispersing fixing seat 1. They are connected to the drone body through pre-set threaded holes by set bolts 6 to achieve overall fixation.

[0029] There are two support blocks 2, both of which are L-shaped. One end of one support block 2 is connected to the side of the stress dispersion fixing seat 1 by bolts, and the other end is connected to the wire harness fixing groove 104 by bolts. One end of the other support block 2 is connected to the stress dispersion fixing seat 1, and the other end is connected to the side plate. The wire harness fixing clip 407 is fixed to the side plate by bolts. The wire harness fixing clip 407 is a two-piece nylon clip with a rubber pad on the inside. One side of the rectangular connecting seat 102 is also connected to a connecting block 3 by bolts. There are two connecting blocks 3, which are respectively connected to the upper guide wheel 405 and the lower guide wheel 406. The guide wheel is made of polyurethane rubber wrapped around a metal hub, and the axis is rotatably connected to the connecting block 3 through a bearing.

[0030] The wire harness storage mechanism 4 is installed in the pre-reserved cavity inside the stress dispersion fixing base 1. The two ends of the central shaft 401 are fixed to the inner wall of the fixing base frame body 101 by bearings. The outer side is nested with a coil spring 402. One end of the coil spring 402 is welded to the central shaft 401, and the other end is engaged with the inner wall of the winding drum 403. The winding drum 403 has an inlet and an outlet facing each other. The inlet is closer to the center of the machine body, and the outlet is farther away from the center of the machine body. The two are 180° apart in the circumferential direction. One end of the wire harness 404 enters the winding drum from the inlet. 403, and is fixed to the inner starting end of the winding drum 403 by a buckle, the other end is led out from the outlet, passes through the lower guide wheel 406 and the upper guide wheel 405, the two wheels are distributed up and down along the wire harness 404, and finally passes through the wire harness fixing clamp 407 and is connected to the UAV moving end module. One end of the wire harness 404 is connected to the main control unit, and the other end passes through the wire harness fixing groove 104 of the stress dispersion fixing seat 1. The elastic pad 105 tightly fits the wire harness 404 to achieve fixation, and the wire entry path avoids moving parts such as the arm rotating shaft.

[0031] Working principle: When the mobile end of the drone is deployed, the wiring harness 404 is subjected to an outward pulling force. This pulling force overcomes the elastic potential energy of the coil spring 402 and drives the winding drum 403 to rotate counterclockwise around the central axis 401. The wiring harness 404 is released from the outlet of the winding drum 403. At this time, the upper guide wheel 405 and the lower guide wheel 406 rotate synchronously with the movement of the wiring harness 404, guiding the wiring harness 404 to move along a preset path. This path is consistent with the extension direction of the drone arm to avoid bending of the wiring harness 404.

[0032] When the movable end is reset, the coil spring 402 releases its elastic potential energy, causing the winding drum 403 to rotate clockwise. The wire harness 404 is wound into the winding drum 403 from the wire inlet. During the winding process, the elastic pad 105 in the wire harness fixing groove 104 constrains the fixed end wire harness 404 to prevent it from shifting with the winding action, ensuring that the wire harness 404 is neatly wound in the inner layer of the winding drum 403.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
