Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) equipment technology, specifically to a collision protection structure and components for a UAV. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices. In fact, UAVs are a general term for unmanned aerial vehicles, which, from a technical perspective, can be categorized as: unmanned fixed-wing aircraft, unmanned vertical takeoff and landing aircraft, unmanned helicopters, unmanned multi-rotor aircraft, and unmanned paragliders.

[0003] For example, Chinese Patent Publication No. CN217496532U discloses a collision protection structure for a drone, including a drone body and a support plate. A rotor shaft is provided on the top of the drone body, a rotor is installed at the end of the rotor shaft, and a support plate is provided at the bottom of the end of the rotor shaft. A first collision protection net is provided below the shaft end protective shell. A fan-shaped protective frame is installed on the edge of the first collision protection net. One end of the fan-shaped protective frame is connected to the support plate, and an arc-shaped protective frame is installed at the other end of the fan-shaped protective frame. A second collision protection net is provided in the middle of the arc-shaped protective frame. A first outer shell is connected to the other end of the support plate near the rotor. The first outer shell and the second outer shell are connected by a cylindrical hinge. A support rod is installed at the bottom of the support plate.

[0004] The solution uses a first anti-collision net and a fan-shaped protective frame to protect the rotor from impacts, and support rods and buffer rods to reduce the impact force when the drone falls after an impact. However, the drone is not only affected by impacts on the rotor during flight. The camera is more valuable than the rotor, and if the camera is damaged in an impact, the drone will be difficult to recover. Furthermore, when the drone falls in an impact, it will not necessarily remain horizontal and land on a level surface. Therefore, the protective ability of the bottom buffer rod is limited. In addition, when the drone is flying in environments with dense buildings or abundant vegetation, if the camera directly impacts a cylindrical object perpendicular to the shell, such as a tree branch, or falls directly onto a slender pole, such as a guardrail, and the diameter of the cylindrical object perpendicular to the shell is smaller than the distance between the two frames, the frames will not be able to block the collision, resulting in damage to the camera. Summary of the Invention

[0005] The purpose of this invention is to provide a collision protection structure and drone components for drones, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

The upper end of the extension block is fixedly connected to the first driving plate or the second driving plate. The lower end of the bracket is provided with a movable groove for the extension block to move. The extension block and the side wall of the movable groove are elastically connected by a spring.

[0011] As a further aspect of the present invention: the anti-collision mechanism includes a first stop and a second stop. The first stop is slidably connected to the upper part of the housing, and the second stop is slidably connected to the bottom of the housing. The first stop and the second stop are symmetrically arranged on the upper and lower sides of the camera module. A movable column is fixedly connected to the end of the second stop away from the camera module. A symmetrical limiting rod is fixedly connected to the lower end of the first stop. A locking block is fixedly connected to the end of the limiting rod away from the first stop. An anti-collision plate is fitted to the lower end of the limiting rod, and the anti-collision plate is slidably connected to the bottom of the inner cavity of the housing.

[0012] As a further embodiment of the present invention: the anti-collision plate is composed of a transparent plate, a transition plate and a retaining plate. The retaining plate is attached to the side of the transition plate near the camera module. The transition plate is elastically connected to the side wall of the camera module by a spring. The transparent plate is fixedly connected to the side of the transition plate near the camera module. The retaining plate is fixedly connected to the side of the transition plate away from the camera module. A retaining groove is provided on the upper part of the retaining plate. The length of the retaining groove is less than the thickness of the retaining plate.

[0013] As a further aspect of the present invention: the antenna is disposed in the middle of the side of the housing away from the camera module, and a protective device is disposed outside the antenna. The protective device includes a protective frame, the antenna is fixedly connected to the bottom of the inner cavity of the protective frame, a movable plate is fixedly connected to the lower end of the protective frame, the movable plate is slidably elastically connected to the bottom of the inner cavity of the housing, and a shell is symmetrically disposed on the upper end of the movable plate. The lower end of the shell is fitted to the upper end of the movable plate, and the shell is fixedly connected to a first driving plate and a second driving plate near the antenna.

[0014] As a further embodiment of the present invention: the inner cavity of the outer shell is slidably connected to a limiting block, the upper end of the movable plate is provided with a limiting hole corresponding to the limiting block, the upper end of the limiting block is fixedly connected to a sliding rod, and the inner cavity of the outer shell is provided with a moving groove for use with the sliding rod, the moving groove being composed of an inclined groove and a horizontal groove.

[0017] By using the shell connecting plate and drive assembly in conjunction, when any shell is impacted, the remaining shells will retract inward. The first and second drive plates drive the anti-collision mechanism and protective device, thus protecting the entire drone regardless of where it is impacted. The second stop lever, moving column, and drive groove work together to achieve bidirectional drive of the second stop lever and the first drive lever. The spring, transition plate, and inclined groove connected to the extension block provide a certain buffer when the drone is subjected to minor collisions such as scrapes and wall friction, preventing immediate protection and affecting the drone's subsequent flight. By setting up a locking block, locking slot, and horizontal groove, the locking block and locking slot can limit the position of the anti-collision plate to prevent it from loosening due to further impact during the drone's fall. The horizontal groove can keep the height of the limiting block unchanged during the slight rebound of the first drive lever, thus achieving an elastic sliding connection between the antenna and the shell, protecting the antenna from breakage due to impact.

[0029] Please see Figure 1-3 In this embodiment of the invention, a collision protection structure for a drone includes a shell 1. Symmetrical brackets 2 are fixedly connected to the outer wall of the shell 1. A sleeve 4 is slidably connected to one end of the brackets 2 away from the shell 1. A camera module 14 is provided on the outer wall of the shell 1. A collision protection mechanism 15 is provided on one side of the outer wall of the shell 1. The input end of the collision protection mechanism 15 is located in the inner cavity of the brackets 2 and connected to the sleeve 4. The collision protection mechanism 15 is located between the symmetrical brackets 2 located near the camera module 14. The collision protection mechanism 15 is located around the camera module 14. A drive assembly 9 for driving the collision protection mechanism 15 is provided in the middle of the bottom wall of the inner cavity of the shell 1. When the sleeve 4 is impacted, the drive assembly 9 extends and retracts inward. The output end of the drive assembly 9 will drive the collision protection mechanism 15 to move closer to the camera module 14 and wrap and protect the camera module 14.

[0030] The drive assembly 9 includes a symmetrical first drive plate 91 and a second drive plate 92. Both the first drive plate 91 and the second drive plate 92 are slidably connected to the inner cavity of the bracket 2. A rack 95 is fixedly connected to the side wall of the first drive plate 91 away from the bracket 2. A gear 94 is rotatably connected to the middle of the bottom wall of the inner cavity of the housing 1. The gear 94 meshes with the rack 95. The first drive plate 91 and the second drive plate 92 are centrally symmetrical about the circular position of the gear 94. An L-shaped rod 93 is fixedly connected to the end of the second drive plate 92 away from the bracket 2. A rack 95 that meshes with the gear 94 is fixedly connected to the side of the L-shaped rod 93 near the gear 94. The L-shaped rod 93 connects the second drive plate 92 and the gear 94, which can change the position of the second drive plate 92 connected to the gear 94. That is, when the first drive plate 91 drives the gear 94 to rotate clockwise, the L-shaped rod 93... The connection position between rack 95 and gear 94 was changed so that when gear 94 rotates clockwise, rack 95 connected to L-shaped rod 93 can follow the rotation direction of gear 94. This allows the first drive plate 91 to move towards the inner cavity of housing 1, and the clockwise rotating gear 94 to extend and retract the second drive plate 92 towards the inner cavity of housing 1, and vice versa. This ensures that when any one of the housings 4 is impacted, i.e., when any one of the first drive plates 91 or the second drive plate 92 moves towards the inner cavity of housing 1, the rest will also move towards the inner cavity of housing 1, thereby driving the anti-collision mechanism 15 to protect the camera module 14. In order to avoid collision between the first drive plate 91 and the second drive plate 92 when they move towards the inner cavity of housing 1, the plane of the first drive plate 91 is specially designed to be higher than the plane of the second drive plate 92.

[0031] The casing 4 is fan-shaped with several through slots on its outer wall. A rotor 3 is installed inside the casing 4, rotatably connected to the upper part of the support 2 away from the casing 1. The top plane of the casing 4 is higher than the upper plane of the rotor 3, thus ensuring the rotor 3 is adequately protected by the casing 4 while the through slots do not obstruct the airflow from the rotor 3. A rotating wheel 5 is installed below the casing 4, rotatably connected to the support 2. The diameter of the rotating wheel 5 is larger than the diameter of the casing 4, meaning that when the casing 4 is impacted, the rotating wheel 5 is impacted before the casing 4. The rotating wheel 5 rotates under force, thus reducing the impact force on the casing 4 to some extent. Furthermore, when the casing 4 only scrapes or rubs against the wall, the rotating wheel 5 can significantly reduce the friction experienced by the casing 4. This increases the service life of the housing 4. A connecting plate 7 is fixedly connected to the middle of the lower end of the housing 4 near the housing 1. An extension block is fixedly connected to the end of the connecting plate 7 away from the housing 4. The upper end of the extension block is fixedly connected to the first drive plate 91 or the second drive plate 92. The lower end of the bracket 2 is provided with a movable groove 8 for the extension block to move. The extension block and the side wall of the movable groove 8 are elastically connected by a spring. This allows the housing 4 and the anti-collision mechanism 15 to be reset in time when the drone is subjected to a small collision or scratch that does not affect normal flight. This prevents the drone from being driven by the anti-collision mechanism 15 to wrap around the camera module 14 immediately after a small scratch, which would affect normal flight. This allows the drone to automatically take different measures when faced with different situations.

[0032] When the drone camera module 14 directly impacts a cylindrical object perpendicular to the housing 1, such as a tree branch, or falls directly onto a slender pole such as a guardrail, if the diameter of the cylindrical object perpendicular to the housing 1 is smaller than the distance between the two housings 4, the housings 4 will not be able to block the collision, resulting in damage to the camera module 14. The anti-collision mechanism 15 includes a first stop 151 and a second stop 152. The first stop 151 is slidably connected to the upper part of the housing 1, and the second stop 152 is slidably connected to the bottom of the housing 1. The first stop 151 and the second stop 152... The first and second baffles 151 and 152 are positioned on the upper and lower sides of the camera module 14, respectively. These baffles will be impacted before the camera module 14, providing comprehensive protection from both top and bottom. This avoids the situation where a single baffle on the upper part of the housing 1 is insufficient to prevent objects between the bottom and upper baffles of the camera module 14 from impacting the drone. A movable column 154 is fixedly connected to the end of the second baffle 152 furthest from the camera module 14, while the first drive plate closer to the camera module 14... The first drive plate 91 and the second drive plate 92 are provided with drive slots 96 for use with the moving column 154. An antenna 16 is provided between the first drive plate 91 and the second drive plate 92, which are far away from the camera module 14. That is, when the first drive plate 91 moves toward the inner cavity of the housing 1, it will drive the moving column 154 to move horizontally toward the inner cavity of the housing 1 through the drive slots 96, thereby driving the second stop rod 152 to move toward the inner cavity of the housing 1. The upper end of the moving column 154 is fixedly connected to the first stop rod 151. That is, when the first drive plate 91 moves, the second stop rod 152 and the first stop rod 154 move together. The stop lever 151 will move synchronously. Conversely, when the second stop lever 152 or the first stop lever 151 is impacted and moves toward the inner cavity of the housing 1, it will also drive the first drive plate 91 and the second drive plate 92 toward the housing 1 in the opposite direction through the moving column 154 and the drive groove 96. The lower end of the first stop lever 151 is fixedly connected to a symmetrical limiting rod 153. The end of the limiting rod 153 away from the first stop lever 151 is fixedly connected to a locking block. The lower end of the limiting rod 153 is fitted with an anti-collision plate 155, which is slidably connected to the bottom of the inner cavity of the housing 1.

[0033] The anti-collision plate 155 consists of a transparent plate, a transition plate, and a retaining plate. The retaining plate is attached to the side of the transition plate closest to the camera module 14. The transition plate is elastically connected to the side wall of the camera module 14 via a spring. The transition plate acts as a buffer when the drone experiences minor scrapes that do not affect flight, preventing the anti-collision plate 155 from immediately protecting the camera module 14 and thus affecting the drone's subsequent flight. The transparent plate is fixedly connected to the side of the transition plate closest to the camera module 14. When the drone is impacted, the spring contracts, pulling the anti-collision plate 155 closer to the camera module 14. At this time, the transparent plate can then wrap around and protect the camera module 14. Using the transparent plate for protection not only prevents the camera module 14 from direct impact and damage, but also allows the camera module 14 to continue capturing images of the drone's surroundings and returning them to the control terminal. After the drone crashes, the operator can quickly locate the drone's position using the returned images. Because the transition plate and camera module 14 are elastically connected... Therefore, if the drone is subjected to a secondary impact during its fall, the transparent plate may become loose, potentially damaging the camera module 14. Therefore, a locking plate is fixedly connected to the side of the transition plate away from the camera module 14. A slot 156 is provided on the upper part of the locking plate, the length of which is less than the thickness of the locking plate. When the first stop lever 151 moves the limiting lever 153 to the position of the locking plate, the anti-collision plate 155 moves closer to and fits against the camera module 14. At this time, the locking block coincides with the vertical plane of the slot 156. Under the rebound action of the spring connected to the growth block, the locking block moves horizontally with the first stop 151. At this time, the locking block will move into the slot 156. Since the first stop 151 can only move horizontally, after the locking block moves into the slot 156, the locking block restricts the movement of the anti-collision plate 155 in the vertical direction relative to the first stop 151. That is, the transparent plate will not loosen in subsequent impacts. In addition, the locking block will also restrict the position of the first drive plate 91 and the second drive plate 92, thereby releasing the limiting fixation of the antenna 16.

[0034] Antenna 16 is located in the middle of the side of housing 1 away from camera module 14. A protective device 13 is provided outside antenna 16. The protective device 13 includes a protective frame 136. Antenna 16 is fixedly connected to the bottom of the inner cavity of the protective frame 136. A movable plate 132 is fixedly connected to the lower end of the protective frame 136. The movable plate 132 is slidably and elastically connected to the bottom of the inner cavity of housing 1. The mounting frame extends out of the inner cavity of housing 1, that is, antenna 16 extends out of the inner cavity of housing 1, so that the UAV can receive signals better. The upper end of the movable plate 132 is symmetrically arranged. The device has a housing 131, the lower end of which is fitted to the upper end of a movable plate 132. The housing 131 is fixedly connected to a first drive plate 91 and a second drive plate 92 near the antenna 16. A limit block 133 is slidably connected inside the housing 131. A limit hole corresponding to the limit block 133 is provided on the upper end of the movable plate 132. When the drone is not impacted, the limit block 133 is located in the limit hole, thereby limiting the position of the movable plate 132, i.e., limiting the position of the antenna 16, thus preventing the drone from being impacted at high speeds. The sudden deceleration during flight causes the movable plate 132 to shake, resulting in the antenna 16 sliding and affecting the drone's signal reception. A sliding rod 135 is fixedly connected to the upper end of the limiting block 133. The inner cavity of the outer shell 131 has a movable groove 134 that works with the sliding rod 135. The movable groove 134 consists of an inclined groove and a horizontal groove. The inclined groove is used to lift the limiting block 133 via the sliding rod 135, allowing the limiting block 133 to disengage from the limiting hole. When the first drive plate 91 moves, it will drive the outer shell 131... The movement lifts the limiting block 133 through the inclined groove. When the first drive plate 91 moves to the limit position, the slide bar 135 moves from the lowest end of the inclined groove to the end of the horizontal groove away from the inclined groove. The horizontal groove can ensure that the height of the limiting block 133 remains unchanged when the first drive plate 91 rebounds slightly. After the limiting of the moving plate 132 is released, when the protective frame 136 is impacted, the antenna 16 will retract into the housing 1. When separated from the impacting object, the antenna 16 will re-extend out of the housing 1 to enhance the signal reception of the UAV.

[0035] A drone component includes a mounting plate 12 located in the middle of the inner cavity of a shell 1. The mounting plate 12 is positioned above a gear 94 and is fixedly connected to the bottom of the inner cavity of the shell 1. A motherboard 11 and a battery 10 are fixedly connected to the upper end of the mounting plate 12. A motor is located in the inner cavity of a bracket 2 near the rotor 3. A camera module 14, an antenna 16, and the motor are all electrically connected to the motherboard 11. A column 6 is located in the middle of the lower end of a rotating wheel 5. The column 6 passes through the rotating wheel 5 and is fixedly connected to the bracket 2. The rotating wheel 5 and the column 6 are rotatably connected. A groove is provided in the middle of the lower end of a casing 4. The width of the groove is greater than the diameter of the column 6, so that the casing 4 will not collide with the column 6 during movement.
