Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicle accessories, in particular to an anti-collision bracket for unmanned aerial vehicles. Background Art

[0002] Currently, a Chinese utility model with announcement number CN221189159U discloses an anti-collision structure for drones. The existing anti-collision brackets are independently mounted on the drone's four propellers. While this can achieve anti-collision protection for the drone's propellers, their installation requires drilling holes in the bracket used to mount the drone's propellers, which are then secured with bolts. This method has significant drawbacks: the installation is complex, drilling holes can cause irreparable damage to the propeller mounting bracket, and the presence of the mounting holes also affects the support strength of the propeller mounting bracket. To address these issues, we propose an anti-collision bracket for drones. Utility Model Content

[0003] The purpose of the utility model is to provide an anti-collision bracket for a UAV, which has the advantage of being easy to quickly adapt and install to various UAVs.

[0004] The above technical purpose of the present utility model is achieved through the following technical solutions: an anti-collision bracket for an unmanned aerial vehicle, comprising a lower chassis, four anti-collision covers fixedly connected to the surface of the lower chassis, two fixed plates fixedly connected to the top of the lower chassis, the internal threads of the fixed plates are connected to clamping screws, the clamping screws are rotatably connected to a U-shaped clamping plate through bearings, two front bars are fixedly connected to one side of the lower chassis, and two rear bars are fixedly connected to the other side of the lower chassis.

[0005] By adopting the above technical solution, the lower chassis is installed on the bottom of the drone by setting up a lower chassis, an anti-collision cover, a fixing plate, a clamping screw, a U-shaped splint, a front block and a rear block. This can prevent the drone from rubbing against the ground during landing, thereby protecting the bottom of the drone; the U-shaped splint can directly clamp the drone when driven by the clamping screw, and under the forward and backward action of the front block and the rear block on the drone, the bracket of this application and the drone can be fixed without the need for drilling and installation.

[0006] The utility model is further configured as follows: two guide grooves are provided inside the fixing plate; guide rods fixedly connected to the U-shaped clamping plate are slidably connected inside the guide grooves.

[0007] By adopting the above technical solution, the U-shaped splint is guided and limited by the setting of the guide groove and the guide rod, so that the U-shaped splint can move linearly and prevent the U-shaped splint from rotating with the rotation of the clamping screw.

[0008] The utility model is further configured as follows: one end of the clamping screw is fixedly connected to a fixing plate, the surface of the fixing plate is fixedly connected to two connecting rods, and the surface of the fixing plate is sleeved with a ring fixedly connected to the connecting rods.

[0009] By adopting the above technical solution, through the setting of the fixed disk and the connecting rod, the number of connecting rods is two. This structural design allows the user to rotate the connecting rod with two fingers, thereby driving the fixed disk to rotate through the connecting rod, and driving the clamping screw to rotate through the fixed disk.

[0010] The utility model is further configured as follows: a hidden groove is opened on one side of the fixing plate, and the collar is located inside the hidden groove.

[0011] By adopting the above technical solution, the hidden groove is provided to store the ring, thereby hiding the ring.

[0012] The utility model is further configured as follows: the four anti-collision covers are respectively sleeved on the surfaces of the four propellers of the UAV.

[0013] By adopting the above technical solution, the anti-collision cover and the propeller sleeve of the drone can avoid collision between the drone propellers.

[0014] The utility model is further configured as follows: the interior of the anti-collision cover is processed into an opening.

[0015] The purpose of adopting the above technical solution and providing an opening inside the anti-collision cover is to facilitate the installation of the drone propeller mounting bracket, so that the drone propeller can be smoothly installed inside the anti-collision cover.

[0016] In summary, the present invention has the following beneficial effects:

[0017] The utility model arranges a lower chassis at the bottom of the drone and two U-shaped clamping plates. Under the rotation of two clamping screws, the two U-shaped clamping plates clamp and limit the drone from moving up and down and left and right. The front and rear bars respectively limit the front and rear sides of the drone. This allows the installation of the anti-collision bracket without drilling holes in the drone propeller bracket. The installation of the anti-collision bracket does not damage the drone propeller bracket and is easy to install and remove. By arranging the lower chassis at the bottom of the drone, the bottom of the lower chassis can serve as a protective chassis when the drone lands, preventing wear on the bottom of the drone.

[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] Example 1:

[0025] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A crash prevention bracket for a drone comprises a lower chassis 1, four crash prevention covers 2 being fixedly connected to the surface of the lower chassis 1, two fixing plates 3 being fixedly connected to the top of the lower chassis 1, a clamping screw 4 being internally threadedly connected to the fixing plates 3, and a U-shaped clamping plate 5 being rotatably connected to the clamping screw 4 via a bearing. Two front bars 6 are fixedly connected to one side of the lower chassis 1, and two rear bars 7 are fixedly connected to the other side of the lower chassis 1. By arranging the lower chassis 1 at the bottom of the drone and providing two U-shaped clamping plates 5, and by the rotation of the two clamping screws 4, the two U-shaped clamping plates 5 clamp and limit the drone from moving up and down and left and right, and cooperating with the front bars 6 and the rear bars 7 to limit the front and rear sides of the drone respectively, the crash prevention bracket can be installed without drilling holes in the drone propeller bracket. The crash prevention bracket can be installed without damaging the drone propeller bracket and is easy to install and remove. By arranging the lower chassis 1 at the bottom of the drone, the bottom of the lower chassis 1 can serve as a protective chassis when the drone lands, preventing wear on the bottom of the drone.

[0026] Furthermore, two guide grooves 8 are provided inside the fixed plate 3, and the guide grooves 8 are slidably connected to guide rods 9 fixedly connected to the U-shaped clamping plate 5. Through the setting of the guide grooves 8 and the guide rods 9, the U-shaped clamping plate 5 is guided and limited, so that the U-shaped clamping plate 5 can move in a straight line and prevent the U-shaped clamping plate 5 from rotating with the rotation of the clamping screw 4.

[0027] Furthermore, one end of the clamping screw 4 is fixedly connected to a fixed disk 10, and two connecting rods 11 are fixedly connected to the surface of the fixed disk 10. The surface of the fixed disk 10 is provided with a ring 12 fixedly connected to the connecting rod 11. Through the arrangement of the fixed disk 10 and the connecting rod 11, the number of connecting rods 11 is two. This structural design makes it easy for the user to rotate the connecting rod 11 with two fingers, thereby driving the fixed disk 10 to rotate through the connecting rod 11, and driving the clamping screw 4 to rotate through the fixed disk 10.

[0028] Furthermore, a hidden groove 13 is provided on one side of the fixing plate 3 , and the collar 12 is located inside the hidden groove 13 . The hidden groove 13 is provided to accommodate the collar 12 , thereby hiding the collar 12 .

[0029] Furthermore, the four anti-collision covers 2 are respectively mounted on the surfaces of the four propellers of the UAV. The anti-collision covers 2 and the propellers of the UAV are mounted to prevent the propellers of the UAV from collision.

[0030] Furthermore, the interior of the anti-collision cover 2 is processed with an opening. The purpose of providing the opening inside the anti-collision cover 2 is to facilitate the installation of the drone propeller mounting bracket, so that the drone propeller can be smoothly installed inside the anti-collision cover 2.

[0031] Brief description of the usage process: When in use, rotate the clamping screw 4 counterclockwise to make the clamping screw 4 drive the U-shaped clamping plate 5 to move toward the clamping screw 4. After the U-shaped clamping plate 5 contacts the side wall of the fixing plate 3, place the lower chassis 1 on the ground, turn the bottom of the drone downward, and place the drone between the two fixing plates 3 from top to bottom.

[0032] After the drone is placed, its four propeller mounting brackets will pass through the openings of the four anti-collision covers 2 respectively, and the four propellers on the four propeller mounting brackets will be located inside the four anti-collision covers 2 respectively, and will be wrapped and protected by the four anti-collision covers 2.

[0033] The front side of the drone will contact the two front bars 6, and the rear side of the drone will contact the two rear bars 7. The drone is restricted by the front bars 6, the rear bars 7 and the bottom chassis 1, and cannot move forward, backward or downward.

[0034] By rotating the two clamping screws 4 clockwise, the two clamping screws 4 push the two U-shaped clamping plates 5 closer to the drone, and the two U-shaped clamping plates 5 are clamped on the left and right sides of the drone, thereby clamping the drone. Under the limitation of the U-shaped structure of the U-shaped clamping plates 5, the drone will not be able to move up and down, and the drone can be fixed at this time.

[0035] To disassemble, rotate the two clamping screws 4 counterclockwise, allowing them to drive one side of the two U-shaped clamping plates 5 into contact with the side walls of the two fixing plates 3. The drone can then be directly removed upwards. No drilling is required during the entire installation process, and no holes will be left after disassembly.

[0036] During the flight of the drone, the anti-collision cover 2 can prevent the propellers of the drone from colliding; the front guard bar 6 and the rear guard bar 7 can prevent the front and rear sides of the drone from colliding; and the lower chassis 1 can prevent the bottom of the drone from colliding when landing.

[0037] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
