Description

Technical Field

[0001] This utility model relates to the field of drone start-stop technology, and in particular to a vehicle-mounted drone fixing mechanism. Background Technology

[0002] With the development of the times, the use of drones is becoming increasingly popular, covering a wider range of fields, including military, industry, and agriculture. In the current era of unprecedented social change and volatile international situations, and with national development strategies aligned with the times, the development of the low-altitude economy has become the mainstream of the industry. As a rising star of this era, drones are experiencing unstoppable growth. However, with the popularity of drones, their disadvantages are becoming increasingly apparent: their short battery life is becoming a stumbling block to the industry's progress, hindering its potential for in-depth and multi-faceted development.

[0003] To address this issue, engineers designed hangars that allow drones to charge and rest, essentially providing them with a small shelter for resupply and rest. However, fixed hangars have limited coverage radius, so vehicle-mounted hangars were designed to expand the coverage area further. But existing technology struggles to meet the demands of dynamic takeoff and landing, stability issues while the vehicle is in motion, unreliable centering and positioning during dynamic takeoff and landing, and unreliable charging. To solve these problems, a vehicle-mounted drone fixing mechanism was developed. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle-mounted drone fixing mechanism to address the above-mentioned shortcomings, thereby solving the problem of insufficient reliability of drones when charging while the vehicle is in motion.

[0005] This utility model is achieved through the following solution:

[0006] A vehicle-mounted drone fixing mechanism includes a drone housing, a magnetic suction component, a locking component, and a charging component. The charging component is located at the center of the bottom of the drone housing. The magnetic suction component surrounds the charging component. One end of the locking component is connected to the bottom plate of the drone housing, and the other end can be driven to fix the bottom plate of the drone to be fixed to the bottom plate of the drone housing.

[0007] Based on the above-mentioned vehicle-mounted UAV fixing mechanism, the overall structure of the UAV nest is funnel-shaped, and the UAV nest includes guide side plates and limiting cavity; the guide side plates are mutually integrated to form a conical cavity structure, and the limiting cavity is located at the center of the conical cavity structure.

[0008] Based on the above-mentioned vehicle-mounted drone fixing mechanism, the size of the limiting cavity is adapted to the base plate of the drone to be fixed.

[0009] Based on the above-mentioned vehicle-mounted drone fixing mechanism, the limiting cavity includes a nest vertical plate and a nest bottom plate; the nest vertical plate is arranged around the nest bottom plate in a circumferential position, so that the limiting cavity extends downward by a predetermined distance; the nest base is provided with a first magnetic suction cavity and a second magnetic suction cavity in a first direction to cooperate with the magnetic suction assembly.

[0010] Based on the above-mentioned vehicle-mounted drone fixing mechanism, the magnetic attraction component includes a first electromagnet and a second electromagnet; the first electromagnet and the second electromagnet are symmetrically arranged along the center position of the drone's base plate; at the same time, at least part of the first electromagnet is embedded in the first magnetic attraction cavity, and at least part of the second electromagnet is embedded in the second magnetic attraction cavity.

[0011] Based on the above-mentioned vehicle-mounted drone fixing mechanism, the charging component is located at the center of the drone nest base plate, and the charging component includes a through-type pin and a drone electrode mounting base; multiple drone electrode mounting bases are arranged along the center of the drone nest, and the through-type pin is located at the bottom of the drone electrode mounting base.

[0012] Based on the above-mentioned vehicle-mounted drone fixing mechanism, the drone base is provided with a first locking cavity and a second locking cavity in the second direction for locking; the first direction and the second direction are not collinear.

[0013] Based on the above-mentioned vehicle-mounted drone fixing mechanism, the locking component includes a servo motor and a rotating arm; the output end of the servo motor is connected to the rotating arm, and the rotating arm can be rotated by the action of the servo motor.

[0014] Based on the above-mentioned vehicle-mounted UAV fixing mechanism, the nest base plate is also provided with an opening slot; the rotating arm can rotate or screw into the opening slot under the action of the servo motor; the rotating arm is provided with a limiting slot and a limiting protrusion, the limiting protrusion protruding from the rotating arm, and the limiting slot is located at the bottom of the limiting protrusion; the thickness of the limiting slot is adapted to the sum of the thickness of the nest base plate and the thickness of the UAV base plate.

[0015] Based on the above-mentioned vehicle-mounted drone fixing mechanism, a support plate and a drainage component are also provided at the bottom of the drone nest; the support plate is arranged around the outer surface of the drone slot; and the drainage component is directly connected to the bottom of the drone nest.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] 1. When the drone returns to the nest, its base plate slides into the bottom of the nest. At this time, the magnetic component can make the drone base and the nest base plate make tight contact. Then, the locking component will fix the drone base to the nest base plate. This ensures that the charging component can always maintain stable contact with the drone base plate during the vehicle's movement, thus completing the charging operation.

[0018] 2. This solution utilizes the conical funnel slope of the drone nest, and through the four-sided limiting of the funnel, allows the drone to slide down the slope and successfully achieve the centering function;

[0019] 3. By using the pulling force of an electromagnet, the drone's base plate is brought into contact with the base plate of the drone's nest, achieving precise positioning;

[0020] 4. By rotating the arm to fix the drone base plate, the drone base plate is made to fit tightly with the base plate of the hangar, so as to firmly lock the drone in the center of the hangar and ensure that the drone can be stably positioned in the hangar in dynamic environments.

[0028] Example 1

[0029] like Figures 1-2 As shown, this utility model provides a technical solution:

[0030] A vehicle-mounted drone fixing mechanism includes a drone nest 1, a magnetic suction component 2, a locking component 3, and a charging component 4. The charging component 4 is located at the center of the bottom of the drone nest 1. The magnetic suction component 2 is arranged around the charging component 4. One end of the locking component 3 is connected to the base plate 122 of the drone nest, and the other end can be driven to fix the drone base plate 7 to the base plate 122 of the drone nest.

[0031] Based on the above structure, when the drone returns to the nest 1, its drone base plate 7 slides into the bottom position of the nest 1. At this time, the magnetic suction component 2 can make the drone base and the base plate of the nest 1 in close contact. Then, the locking component 3 is activated to fix the drone base on the nest base plate 122. In this way, the charging component 4 can always be stably in contact with the drone base plate 7 during the vehicle's movement to complete the charging operation.

[0032] As an example, the nest 1 has an overall funnel-shaped structure. The nest 1 may include guide side plates 11 and limiting cavities 12. The guide side plates 11 are interlocked to form a conical cavity structure, and the limiting cavity 12 is located at the center of the conical cavity structure.

[0033] The size of the limiting cavity 12 is adapted to the base plate 7 of the drone to be fixed.

[0034] Based on the above structure, when the drone returns to the nest 1, its base plate 7 for charging will slide with the guide side plate 11 and the limiting cavity 12, so that the drone base plate 7 can quickly enter the predetermined charging area for charging.

[0035] As an example, the limiting cavity 12 may include a nest vertical plate 121 and a nest bottom plate 122; the nest vertical plate 121 is arranged around the nest bottom plate 122 in a circumferential position, so that the limiting cavity 12 extends downward by a predetermined distance; a first magnetic suction cavity 123 and a second magnetic suction cavity 124 that cooperate with the magnetic suction assembly 2 are provided in a first direction of the base of the nest 1.

[0036] The magnetic attraction component 2 may include a first electromagnet 21 and a second electromagnet 22; the first electromagnet 21 and the second electromagnet 22 are symmetrically arranged along the center position of the bottom plate 122 of the machine nest; at the same time, the first electromagnet 21 is at least partially embedded in the first magnetic attraction cavity 123, and the second electromagnet 22 is at least partially embedded in the second magnetic attraction cavity 124.

[0037] Based on the above structure, the electromagnet is embedded in the magnetic suction cavity. When the drone base plate 7 is guided into the limiting cavity 12, it can directly make initial contact with the electromagnet. After the electromagnet is energized, the first electromagnet 21 and the second electromagnet 22 can make close contact with the drone base plate 7. The first electromagnet 21 and the second electromagnet 22 arranged on opposite sides can make the drone base plate 7 more evenly stressed during magnetic attraction.

[0038] As an example, the charging assembly 4 is located at the center of the nest base plate 122. The charging assembly 4 may include through-hole pins 41 and drone electrode mounting bases 42. Multiple drone electrode mounting bases 42 are arranged along the center of the nest 1, and the through-hole pins 41 are located at the bottom of the drone electrode mounting bases 42. There are 10 through-hole pins 41.

[0039] Based on the above structure, the charging operation can be performed by contacting the drone base plate 7 through the through-type pin 41 and the drone electrode mounting base 42.

[0040] As an example, a first locking cavity 125 and a second locking cavity 126 that engage with locking are provided in the second direction of the base of the machine nest 1; the first direction and the second direction are not collinear;

[0041] The locking assembly 3 may include a servo motor 31 and a rotating arm 32; the output end of the servo motor 31 is connected to the rotating arm 32, and the rotating arm 32 can be rotated by the action of the servo motor 31.

[0042] An opening slot 127 is also provided on the base plate 122 of the engine compartment; the rotating arm 32 can rotate or screw into the opening slot 127 under the action of the servo motor 31.

[0043] Based on the above structure, by setting the locking cavity and the magnetic suction cavity to be non-collinear, interference between components can be avoided. By setting the opening slot 127 on the nest base plate 122, the rotating arm 32 can be rotated out of the opening slot 127 during use to lock the drone base plate 7 and the nest base plate 122. When not in use, the rotating arm 32 can be screwed into it for placement to avoid damage to the rotating arm 32.

[0044] As an example, a limiting slot 321 and a limiting protrusion 322 can be provided on the rotating arm 32. The limiting protrusion 322 protrudes from the rotating arm 32, and the limiting slot 321 is located at the bottom of the limiting protrusion 322. The thickness of the limiting slot 321 is adapted to the sum of the thickness of the nest base plate 122 and the thickness of the UAV base plate 7.

[0045] Based on the above structure, when the rotating arm 32 is driven to rotate, it can precisely engage the base plate 122 and the drone base plate 7 into the limiting slot 321, thereby restricting the drone base plate 7 in the left and right directions. At the same time, the limiting protrusion 322 contacts the drone base plate 7, thereby restricting the drone base plate 7 in the up and down directions. Furthermore, the locking component 3 on the opposite side locks both sides of the drone base, further preventing the drone base plate 7 from moving between the drone base plate 7 and the charging component 4 during vehicle operation.

[0046] As an example, the bottom of the machine nest 1 may also be provided with a support plate 5 and a drainage component 6; the support plate 5 is arranged around the outer surface of the machine slot; the drainage component 6 is directly connected to the bottom of the machine nest 1.

[0047] Based on the above structure, the entire charging assembly 4 and the charging chamber 1 are lifted by the support plate 5, and the water that may be generated is drained away by the drainage component 6 to ensure safety during charging.

[0048] In this solution, 10 through-type pins 41 are installed on the UAV electrode mounting base 42, 2 electromagnets, 2 servo motors 31, and 2 rotating arms 32 are installed together on the nest base plate 122; the assembled nest base plate 122 and the nest 1 drainage accessories and support plate 5 are a total of 2 pieces.

[0049] The upper part of the nest 1 is connected to the external support, and the lower part is embedded with the drainage accessories of the nest 1; during the take-off and landing of the drone, it contacts the base plate 7 through the drone's base plate; under the combined action of the electromagnet and the rotating arm 32, the drone's fixing and charging functions are satisfied. The detailed steps are as follows:

[0050] Drone landing process: Electromagnet is energized - Drone base plate 7 and nest base plate 122 are in close contact - Rotating arm 32 rotates and locks drone base plate 7 - Electromagnet is de-energized;

[0051] Drone takeoff process: Electromagnet is energized - rotating arm 32 rotates to fully release drone base plate 7 - electromagnet is de-energized - drone takes off; the drone and hangar repeat this process to achieve long-term operation.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
