Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a flying lifebuoy storage and power replenishment system. Background Art

[0002] Drones are now commonly used carriers and equipment in various fields, and can be used for shooting, tracking, transportation, rescue and many other purposes.

[0003] Among them, the existing patent with announcement number CN217348190U specifically discloses an electric flying lifebuoy, which mainly includes a ring body located in the middle and four rotors located outside the ring body.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Figures 1-3 As shown, the present invention provides a flying lifebuoy storage and charging system, comprising a housing 1 and a bracket 11 disposed in the housing 1. A main charging unit 4 and a charging unit 5 are disposed within the bracket 11. The main charging unit 4 is disposed outside the housing 1 and can be used to connect to an external power source to transmit electrical energy to the housing 1. The charging unit 5 includes charging contacts disposed on the bracket 11 and on the flying lifebuoy. When storing the flying lifebuoy, the flying lifebuoy is placed restrictively on the bracket 11. After the main charging unit 4 is connected to the external power supply, the electric energy is sent into the flying lifebuoy through the power supply contacts, thereby avoiding the power outage caused by long-term storage of the flying lifebuoy.

[0025] However, if a large number of flying lifebuoys are actually stored, and if each box 1 is connected to an external power supply, the wiring of the flying lifebuoy power supply will be very complicated and increase safety risks. Therefore, in the present invention, an adapter unit is also provided in the box 1. A bracket 11 identical to the bracket 11 on the upper side of the box 1 is provided. The adapter unit specifically includes a power supply unit 7 provided in the upper bracket 11 and a secondary charging unit 8 provided in the lower bracket 11. The power supply unit 7, the secondary charging unit 8 and the main charging unit 4 in the same box 1 are all electrically connected. When multiple flying lifebuoys are to be recharged, the boxes 1 are stacked vertically, with the box 1 at the bottom connected to an external power supply, and the other boxes 1 are electrically connected through the adapter unit, with the power supply terminal 71 and the auxiliary charging terminal 82 in the power supply part 7 and the auxiliary charging part 8 respectively contacting and connecting them, thereby realizing the recharging of the flying lifebuoy in the upper box 1, thereby avoiding the situation of recharging in a messy manner.

[0026] The above-mentioned middle box 1 includes an upper cover 2 and a lower box 3. In normal use, the lower box 3 is usually placed directly on the ground or in other more complex environments, which can easily cause wear and tear on the secondary charging terminal 82, affecting subsequent charging. Therefore, in the present invention, the lower end of the bracket 11 located on the lower side is provided with a secondary charging slot 81 extending from bottom to top, and the lower box 3 is provided with a secondary charging port aligned with the secondary charging slot 81. The secondary charging terminal 82 that can move up and down is provided in the secondary charging slot 81; during charging, the secondary charging terminal 82 is controlled to move downward to the secondary charging port and contact the power supply terminal 71. In addition, the secondary charging terminal 82 is controlled to be retracted into the secondary charging slot 81 to avoid wear and tear.

[0027] To specifically control the movement of the auxiliary charging terminal 82, a pull wire 92 is connected to the upper side of the auxiliary charging terminal 82 and a charging thrust spring 91 is provided in the auxiliary charging slot 81. The pull wire 92 drives the auxiliary charging terminal 82 to move into the auxiliary charging slot 81. When the pull wire 92 is relaxed, the charging thrust spring 91 pushes the auxiliary charging terminal 82 downward, thereby achieving the purpose of automatic charging.

[0028] In combination with the above structure, a control box 9 is also provided in the center of the lower box 3. One end of the pull wire 92 extends into the control box 9, and the end of the pull wire 92 is fixedly connected to the control terminal 94. A power-off thrust spring 93 is provided between the inner wall of the control box 9 and the control terminal 94. A power-on trigger terminal 10 is also provided on the upper side of the upper cover 2. When the box body 1 is stacked for power supply, the power-on trigger terminal 10 extends into the control box 9 and is squeezed between the power-on trigger terminal 10, so that the power-on trigger terminal 10 compresses the power-off thrust spring 93, that is, relaxes the pull wire 92, so that under the action of the power-on thrust spring 91, the auxiliary charging terminal 82 moves downward until it contacts the power supply terminal 71.

[0029] In addition, the power replenishment trigger terminal 10 is composed of an elastic arc-shaped metal sheet. A sliding groove for plugging in the two ends of the metal sheet is preset on the upper side of the upper cover 2, and the middle of the metal sheet is bent and convex upward. When the box body 1 is stacked, the metal sheet is first subjected to the pressure of the box body 1, and the two ends of the metal sheet move into the sliding groove and deform until the four corners between the box bodies 1 are aligned. At this time, the metal sheet is aligned with the open mouth on the lower side of the control box 9, and the metal sheet restores its shape again and extends into the control box 9, and the metal sheet collides with the inner wall of the control box 9 to make a sound, so that it can be determined whether the alignment work before power replenishment is completed, and when pulling the upper box body 1, the metal sheet can still be squeezed and deformed, thereby facilitating the pulling and pushing of the high-level box body 1 for stacking and replenishing power.

[0030] The working principle of the present invention is: When storing the flying lifebuoy, place the flying lifebuoy in the box 1. At this time, the power supply contacts on the flying lifebuoy are in contact with the power supply contacts on the bracket 11. By connecting the power supply to the main charging unit 4 of the box 1, electric energy is transmitted to the flying lifebuoy for power supply.

[0031] In addition, when the flying lifebuoys in multiple boxes 1 are charged, the boxes 1 are stacked. Except for the bottom box 1 connected to the external power supply, the other boxes 1 transmit power through the adapter unit to complete the charging of multiple flying lifebuoys.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features in the embodiments with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
