Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted drone technology, and more particularly to a vehicle-mounted drone and its unfolding and folding method. Background Technology

[0002] With the development of drone technology, travel enthusiasts, campers, and aerial photography enthusiasts are increasingly relying on drones for filming, especially the demand for vehicle-mounted drones. However, the folding and unfolding of the cantilever arms of traditional drones is done manually. When storing, the drone cantilever arms are manually folded and then placed in the drone's casing; they cannot be actively folded. When unfolding, the drone cantilever arms are manually opened; they also cannot be actively opened.

[0003] Furthermore, traditional drone support feet are either positioned at the lower part of the fuselage, resulting in an excessively large size for the drone in the Z-axis direction; or positioned directly below the rotor on the cantilever, which reduces the drone's size in the Z-axis direction but still occupies space in that direction. Regardless of the support foot configuration, due to the limited depth and thickness of the external spare tire compartment, it is not suitable to place it on top of the external spare tire compartment of an SUV. Summary of the Invention

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. To make the technical solutions and advantages of this application clearer, the vehicle-mounted drone and its unfolding and folding method will be described in detail below with reference to the accompanying drawings.

[0038] This application provides a vehicle-mounted drone, such as Figure 1 As shown, the vehicle-mounted drone includes: a main frame 1, a secondary frame 2, and a cantilever drive mechanism 5;

[0039] Sub-frame 2 is connected to main frame 1 via support rod 12;

[0040] Two cantilever arms 6 are respectively set at both ends of the main frame 1. The end of each cantilever arm 6 is connected to the motor rotor assembly 7 and the support leg 8. The two cantilever arms 6 at both ends of the main frame 1 are hinged by sliding pins 60. A guide groove 10 is set on the main frame, and the two sliding pins 60 are slidably connected to the guide groove 10.

[0041] The cantilever drive mechanism 5 is connected to the main frame 1. Both sliding pins 60 are connected to the cantilever drive mechanism 5. The cantilever drive mechanism 5 can drive the two sliding pins 60 to move towards and away from each other along the guide groove 10, so as to realize the folding and unfolding of the cantilever 6.

[0042] This application provides a vehicle-mounted drone, in which two cantilever arms 6 located at the same end are hinged by sliding pins 60. The two sliding pins 60 are slidably connected to guide grooves 10. Both sliding pins 60 are connected to a cantilever drive mechanism 5. The cantilever drive mechanism 5 can drive the two sliding pins 60 to move towards and away from each other along the guide grooves 10, thereby realizing the simultaneous active folding and unfolding of the four cantilever arms 6, reducing the size in the X and Y coordinate axes, and making it suitable for parking on the upper part of the spare tire box of an SUV's external spare tire.

[0043] In some embodiments, the lower end of the main frame 1 is connected to the battery compartment 3;

[0044] The lower end of the battery compartment 3 is connected to the magnetic base 4.

[0045] In order to provide constraints on the movement of the cantilever 6, in some embodiments of this application, such as Figure 1 , Figure 2 As shown, a long groove 61 is provided on the cantilever 6, and the cantilever 6 is connected to the support rod 12 through the long groove 61.

[0046] It should be noted that the motor rotor assembly 7 and the support legs 8 are both connected to the end of the cantilever 6 away from the main frame 1; the auxiliary frame 2 is connected to the upper end of the main frame 1 through four support rods 12; the four cantilever 6 are connected to the four support rods 12 one by one through long slots 61.

[0047] In some embodiments, the support leg 8 is hinged to the cantilever 6, and the support leg 8 rotates about the hinge point to achieve folding and unfolding.

[0048] In some embodiments of this application, such as Figure 2 As shown, the support frame 8 includes two side frame plates 80, a support sleeve 81, and a torsion spring pin 82; the two side frame plates 80 are connected by the support sleeve 81, and the two side frame plates 80 are also connected to the cantilever 6 by the torsion spring pin 82. The two side frame plates 80 can rotate around the torsion spring pin 82, and when the two side frame plates 80 rotate toward the main frame 1, the support frame 8 can be folded.

[0049] It should be noted that the two side frame plates 80 are symmetrically arranged on both sides of the cantilever 6. The upper part of the side frame plates 80 is located above the cantilever 6, and the lower part of the two side frame plates 80 is located below the cantilever 6. In order to provide a limit for the unfolding of the support leg 8, in some embodiments of this application, the upper part of the two side frame plates 80 is connected to the limiting sleeve 83, and the limiting sleeve 83 provides a limit for the unfolding of the support leg 8.

[0050] In some embodiments of this application, the lower parts of the two side frame plates 80 are connected to rollers 84.

[0051] In some embodiments, such as Figure 5 As shown, the cantilever drive mechanism 5 includes a motor 50, a push-pull part 1 52-2, a push-pull part 2 53-2, a rack 1 52, and a rack 2 53. The motor 50 is connected to the main frame 1. A gear 50-1 is provided on the output shaft of the motor 50. Both rack 1 52 and rack 2 53 are meshed with the gear 50-1. Push-pull part 1 52-2 is connected to rack 1 52, and push-pull part 2 53-2 is connected to rack 2 53. Push-pull part 1 52-2 and push-pull part 2 53-2 are connected to two sliding pins 60 in a one-to-one correspondence.

[0052] It should be noted that the cantilever drive mechanism 5 also includes a spacer sleeve 51. The motor 50 is fastened to the main frame 1 through the spacer sleeve 51. The spacer sleeve 51 provides space for the installation of rack 1 52 and rack 2 53. Push-pull part 1 52-2 and push-pull part 2 53-2 are respectively sleeved on two sliding pins 60.

[0053] To provide guidance for the movement of rack 52 and rack 53, in some embodiments of this application, such as Figure 3 As shown, two guide slots 11 are provided on the main frame 1;

[0054] A guide part 52-1 is provided on rack 1 52; a guide part 53-1 is provided on rack 2 53.

[0055] Guide section 1 52-1 and guide section 2 53-1 are slidably connected to the two guide grooves 2 11 in a one-to-one correspondence.

[0056] It should be noted that rack 1 52 and rack 2 53 are located on both sides of gear 50-1, and the corresponding two guide grooves 2 11 are located on both sides of gear 50-1, and the setting direction of the two guide grooves 2 11 is consistent with the setting direction of guide groove 1 10. Guide part 1 52-1 is slidably connected to one of the guide grooves 2 11, and guide part 2 53-1 is slidably connected to the other guide groove 2 11. Push-pull part 1 52-2 and push-pull part 2 53-2 are located on both sides of motor 50; when motor 50 outputs... When the shaft rotates, it drives the gear 50-1 to rotate, which in turn drives the rack 52 and rack 53 to move in opposite directions. Through the cooperation of the guide part 52-1 and guide part 53-1 with the two guide grooves 11, the movement of the rack 52 and rack 53 is guided. The rack 52 and rack 53 move in opposite directions, which can drive the two sliding pins 60 to move towards or away from each other through the push-pull part 52-2 and push-pull part 53-2, so as to realize the folding or unfolding of the cantilever 6.

[0057] In some embodiments, a winding wheel 50-2 is also provided on the output shaft of the motor 50, and a steel wire rope 13 is attached to the support sleeve 81. The other end of the steel wire rope 13 is connected to the winding wheel 50-2.

[0058] In order to guide the movement of the wire rope 13, some embodiments of this application, such as Figure 4 As shown, a guide roller 62 is installed on the cantilever 6, and the wire rope 13 passes over the upper end of the guide roller 62, then passes over the support rod 12 and is fixedly connected to the winding wheel 50-2.

[0059] When the output shaft of motor 50 rotates, it drives the take-up reel 50-2 and gear 50-1 to rotate simultaneously. The rotation of take-up reel 50-2 causes the wire rope 13 to wind around or be released from the take-up reel 50-2. When the wire rope 13 is wound around the take-up reel 50-2, it pulls the support sleeve 81, causing the support leg 8 to rotate around the torsion spring pin 82 toward the main frame 1, thus folding the support leg 8. When the wire rope 13 is released from the take-up reel 50-2, under the elastic restoring force of the torsion spring pin 82, it causes the support leg 8 to rotate around the torsion spring pin 82 away from the main frame 1, thus unfolding the support leg 8.

[0060] The vehicle-mounted drone provided in this application, after flying back to the top of the spare tire box of an off-road SUV with an externally mounted spare tire, requires the cantilever 6 and support bracket 8 to be folded and stored, so that the entire vehicle-mounted drone can adapt to the depth and thickness dimensions of the externally mounted spare tire box. The specific folding and storage process of the vehicle-mounted drone provided in this application is as follows:

[0061] In the cantilever drive mechanism 5, the motor 50 drives the gear 50-1 and the winding wheel 50-2 to rotate counterclockwise simultaneously. The guide portion 52-1 on rack 52 moves towards the center under the guidance of guide groove 11. Rack 52, through push-pull portion 52-2, pulls the sliding pin 60, causing the two hinged cantilever arms 6 to move towards the center. Simultaneously, under the constraint of support rod 12, the included angle between the two hinged cantilever arms 6 decreases. Similarly, the guide portion 53-1 on rack 53 moves towards the center under the guidance of guide groove 11. Rack 53, through push-pull portion 53-2, pulls the sliding pin 60, causing the two hinged cantilever arms 6 to move towards the center. Simultaneously, under the constraint of support rod 12, the included angle between the two hinged cantilever arms 6 decreases. This allows for the simultaneous active folding and storage of all four cantilever arms 6, reducing the dimensions in the X and Y axes, making it suitable for placement on top of the spare tire compartment of an SUV's externally mounted spare tire.

[0062] While the cantilever 6 is folded and stored, the winding wheel 50-2 rotates counterclockwise, pulling the support sleeve 81 through the steel wire rope 13. This overcomes the elastic restoring force of the torsion spring in the torsion spring pin 82, causing the support leg 8 to rotate around the torsion spring pin 82 towards the main frame 1, thus achieving the folding of the support leg 8 and reducing the dimension in the Z-axis direction.

[0063] Before a vehicle-mounted drone can take off from the top of the spare tire box of an externally mounted spare tire, the cantilever 6 and the support legs 8 need to be deployed. The specific deployment process is as follows:

[0064] In the cantilever drive mechanism 5, the motor 50 drives the gear 50-1 and the winding wheel 50-2 to rotate clockwise simultaneously. The guide portion 52-1 on rack 52 moves outward under the guidance of guide groove 11. Rack 52 pulls the sliding pin 60, along with the two hinged cantilever arms 6, outward via push-pull portion 52-2. Simultaneously, under the constraint of support rod 12, the included angle between the two hinged cantilever arms 6 increases. Similarly, the guide portion 53-1 on rack 53 moves outward under the guidance of guide groove 11. Rack 53 pulls the sliding pin 60, along with the two hinged cantilever arms 6, outward via push-pull portion 53-2. Simultaneously, under the constraint of support rod 12, the included angle between the two hinged cantilever arms 6 increases. This achieves the simultaneous active deployment of all four cantilever arms 6.

[0065] As the cantilever 6 unfolds, the winding wheel 50-2 rotates clockwise, and the wire rope 13 relaxes the tension on the support sleeve 81. Under the action of the elastic restoring force of the torsion spring in the torsion spring pin 82, the support leg 8 rotates around the torsion spring pin 82 in a direction away from the main frame 1, thereby realizing the unfolding of the support leg 8.

[0066] This application provides a vehicle-mounted drone, which has two cantilever arms 6 at the same end hinged by sliding pins 60. The two sliding pins 60 are slidably connected to guide grooves 10 and both sliding pins 60 are connected to a cantilever drive mechanism 5. The cantilever drive mechanism 5 can drive the two sliding pins 60 to move towards and away from each other along the guide grooves 10, thereby realizing the simultaneous active folding and unfolding of the four cantilever arms 6, reducing the size in the X and Y coordinate axes, and making it suitable for parking on the upper part of the spare tire box of an SUV's external spare tire. In addition, a support bracket 8 is hinged to the cantilever arms 6. The support bracket 8 is connected to the winding wheel 50-2 in the cantilever drive mechanism 5 through a steel wire rope 13, so that the folding and unfolding of the support bracket 8 is synchronized with the folding and unfolding of the cantilever arms 6.

[0067] This application also provides a method for unfolding and folding a vehicle-mounted drone, including:

[0068] The cantilever drive mechanism 5 drives two sliding pins 60 to move towards each other along the guide groove 10, thus folding the cantilever 6.

[0069] The cantilever drive mechanism 5 drives two sliding pins 60 to move in opposite directions along the guide groove 10, thus unfolding the cantilever 6.
