Description

Technical Field

[0001] This utility model relates to the technical field of unmanned aerial vehicles (UAVs), and more specifically, to a chassis component and an UAV. Background Technology

[0002] A drone is an unmanned aerial vehicle (UAV) that flies and performs tasks autonomously through computer systems and sensors. It has wide applications in many fields. For example, in aviation, drones are used for aerial photography, aerial mapping, and search and rescue; in agriculture, they are used to monitor farmland conditions, including soil moisture, crop health, and the spread of pests and diseases; and in environmental monitoring and disaster response, they can monitor air pollutants, water quality, and forest fires. Drone obstacle avoidance devices are safety equipment used to help drones avoid collisions in areas with numerous obstacles such as urban buildings, trees, and power lines. They typically use various sensors and radar technologies to perceive the surrounding environment in real time and issue timely warnings or automatically adjust their flight paths.

[0003] Chinese utility model patent CN220974564U discloses an obstacle avoidance device for unmanned aerial vehicles (UAVs), including a frame, an obstacle avoidance mechanism, and an anti-collision mechanism. A motor is fixedly installed on the side wall of the frame, and blades are fixedly installed on the output end of the motor. The obstacle avoidance mechanism includes a mounting base, a limiting block, and a pressing block. The mounting base is fixedly installed on the upper part of the frame, and a radar is installed in the inner cavity of the mounting base.

[0004] The aforementioned drones mainly reduce the risk of collision by adding anti-collision mechanisms to both sides of the frame. However, due to the radar and other mechanisms installed on the drone frame, the drone itself is quite heavy, and the frame is subjected to relatively large forces and is prone to damage when the drone lands. Utility Model Content

[0005] Therefore, in order to solve the problem that some drones, due to their large weight, experience relatively high stress on their chassis during landing, making them prone to damage, this utility model provides a chassis component and a drone, the specific technical solution of which is as follows:

[0006] On one hand, a base frame component includes a frame body, a stopping assembly, and a swing assembly; the stopping assembly includes two support units disposed at the bottom of the frame body, each support unit including a support rod, the support rod being inclined outwards from the bottom plane of the frame body; the swing assembly includes two connecting units respectively connecting the two support units to the frame body, each connecting unit including a connecting frame hinged to the frame body, and a tension spring connecting the support rod and the connecting frame; the support rod is provided with a hinged end hinged to the frame body, a spring-loaded portion connecting the tension spring, and a connecting portion hinged to the connecting frame.

[0007] The aforementioned base frame components utilize outward-sloping support rods at the bottom of the frame, connected to the connecting frame by tension springs. When the drone lands, the tension springs absorb some of the impact force and are stretched, allowing the support rods to swing outward relative to the frame, thus ensuring the base frame remains stable and reliable in the event of excessive stress.

[0008] Furthermore, the frame is provided with a connecting seat, and the connecting unit includes a connecting rod that connects the connecting seat and the connecting frame.

[0009] Furthermore, the spring-loaded part is a first collar disposed on the support rod, and the connecting part is a second collar disposed on the support rod; the support rod is respectively provided with positioning grooves that adapt to the first collar and the second collar.

[0010] Furthermore, the distance between the hinge end and the second collar is a first distance, the distance between the second collar and the first collar is a second distance, and the ratio of the second distance to the first distance is greater than 2.

[0011] Furthermore, the swing assembly also includes a swing limiting unit, wherein the connecting rod has a connecting end hinged to the connecting frame and a swing end hinged to the connecting seat; the swing limiting unit includes a swing block connected to the swing end hub and a limiting seat disposed on the connecting seat.

[0012] Furthermore, the support unit includes a placement flat rod disposed at the other end of the support rod, and the end of the placement flat rod is provided with a buffer sleeve.

[0013] Furthermore, a protective unit is provided at the bottom of the frame, the protective unit including at least four protective blocks protruding from the bottom surface of the frame.

[0014] Furthermore, the protection unit includes six protection blocks, and the side of each protection block away from the frame is provided with a rubber layer.

[0015] On the other hand, an unmanned aerial vehicle (UAV) includes a drive wing component and a base frame component; the drive wing component includes a drive seat connected to the frame and a plurality of drive wing assemblies disposed on the drive seat.

[0016] Furthermore, it also includes a power supply unit mounted on the frame; the drive wing assembly includes six drive wing units, each drive wing unit including a drive motor electrically connected to the power supply unit, a drive wing body driven by the drive motor, and a mounting arm connecting the drive motor and the drive base.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with its embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit its scope of protection.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0037] On the one hand, such as Figure 1 and Figure 2 , Figure 3 , Figure 4 As shown, a base frame component in one embodiment of the present invention includes a frame body 1, a stopping component 2, and a swing component 3. The stopping component 2 includes two support units 21 disposed at the bottom of the frame body 1. Each support unit 21 includes a support rod 22, which is inclined outward from the bottom plane of the frame body 1. The swing component 3 includes two connecting units 31 that respectively connect the two support units 21 to the frame body. Each connecting unit 31 includes a connecting frame 32 hinged to the frame body 1 and a tension spring 33 connecting the support rod 22 and the connecting frame 32. The support rod 22 is provided with a hinge end 221 hinged to the frame body 1, a spring-loaded part 222 connecting the tension spring 33, and a connecting part 223 hinged to the connecting frame 32.

[0038] The aforementioned base frame component has a support rod 22 inclined outward at the bottom of the frame 1, and a tension spring 33 connects the support rod 22 and the connecting frame 32. When the UAV lands, the tension spring 33 can absorb part of the impact force and be stretched, and the support rod 22 can swing outward relative to the frame 1, thereby ensuring that the base frame is not damaged due to excessive force, and the structure is stable and reliable.

[0039] In one embodiment, the frame 1 is provided with a connecting seat 11, and the connecting unit 31 includes a connecting rod 34 connecting the connecting seat 11 and the connecting frame 32. Thus, by using the connecting rod 34 to assist in the connection to the connecting seat 11, the swinging motion of the swing assembly 3 becomes more stable and reliable.

[0040] In one embodiment, the spring-loaded portion 222 is a first collar disposed on the support rod 22, and the connecting portion 223 is a second collar disposed on the support rod 22; the support rod 22 is respectively provided with positioning grooves for adapting to the first collar and the second collar. Thus, by fitting the first collar and the second collar onto the positioning grooves respectively, axial movement of the first collar and the second collar on the support rod 22 is prevented, thereby ensuring the swinging effect of the swing assembly 3.

[0041] In one embodiment, the distance between the hinge end 221 and the second collar is a first distance, and the distance between the second collar and the first collar is a second distance, wherein the ratio of the second distance to the first distance is greater than 2. Thus, by defining the positional relationship between the hinge end 221, the spring-loaded part 222, and the connecting part 223, a certain buffer space is ensured.

[0042] In one embodiment, the swing assembly 3 further includes a swing limiting unit 35. The connecting rod 34 has a connecting end hinged to the connecting frame 32 and a swing end hinged to the connecting seat 11. The swing limiting unit 35 includes a swing block 351 connected to the swing end hub and a limiting seat 352 disposed on the connecting seat 11. Thus, when the support rod 22 swings, the swing block 351 also swings. The limiting seat 352 limits the swing position of the swing block 351, thereby preventing the support rod 22 from swinging too much and interfering with other mechanisms.

[0043] In one embodiment, the support unit 21 includes a placement flat rod 23 disposed at the other end of the support rod 22, and the end of the placement flat rod 23 is provided with a buffer sleeve 231. Thus, when the drone lands, the buffer sleeve 231 contacts the ground, buffering a portion of the impact force.

[0044] In one embodiment, the frame 1 is provided with a protective unit 12 at its bottom, the protective unit 12 including at least four protective blocks 13 protruding from the bottom surface of the frame 1. Thus, when the drone descends at too high a speed and the resulting impact force is too great, and the swing assembly 3 cannot completely buffer the impact force, the protective blocks 13 can provide a certain degree of protection by contacting the ground.

[0045] In one embodiment, the protection unit 12 includes six protection blocks 13, each of which has a rubber layer on the side away from the frame 1. This rubber layer absorbs a certain amount of impact force, thus enhancing the protective effect.

[0046] On the one hand, such as Figure 5 As shown, an embodiment of the present invention provides a drone including a drive wing component 4 and a base frame component 5; the drive wing component 4 includes a drive seat 41 connected to the frame 1 and a plurality of drive wing assemblies 42 disposed on the drive seat 41.

[0047] In one embodiment, a power supply unit 6 is also included, mounted on the frame 1. The drive wing assembly 42 includes six drive wing units 43, each drive wing unit 43 including a drive motor 431 electrically connected to the power supply unit 6, a drive wing body 432 driven by the drive motor 431, and a mounting arm 433 connecting the drive motor 431 to the drive base 41. Thus, the six drive wing units 43 better balance the overall weight of the UAV, ensuring stability during flight and landing.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
