Description

Technical Field

[0001] This invention belongs to the technical field of UAV storage and launch boxes, specifically relating to a box cover sealing and locking structure and a UAV storage and launch box. Background Technology

[0002] Reliable sealing during long-term storage of the drone within the launch box and reliable, convenient opening during launch are two crucial functions of a drone launch box. Existing drone launch boxes offer various methods for opening the lid, such as: manual opening via multiple screws connecting the box and lid; manual opening via latches; opening via explosive bolts (explosive bolt breakage and throwing); opening via explosive cords; and more complex methods involving mechanical or hydraulic opening mechanisms.

[0003] However, existing drone launcher box designs, while ensuring a reliable seal at the box opening, struggle to guarantee the reliability and ease of opening the lid. Conversely, launcher boxes that achieve reliable and easy lid opening often fail to maintain a reliable seal at the box opening, making a compromise impossible. More importantly, existing launcher box connection structures suffer from significant weight (common mechanical or hydraulic opening mechanisms typically weigh over 100 kilograms) and lengthy lid opening times; even with relatively convenient designs, opening the lid generally takes about twenty seconds. Furthermore, some launcher boxes employ fragile lid structures, but these often fail to achieve damage-free launches of the drone. Summary of the Invention

[0004] In order to solve the technical problems mentioned in the background art, the present invention aims to provide a box cover sealing and locking structure and a UAV storage and launch box, which can at least take into account the two functions of reliable sealing of the box opening and reliability and convenience when the box cover is opened.

[0005] The present invention adopts the following technical solution.

[0006] A box lid sealing and locking structure includes a sealing ring disposed at the mating part of the box lid and the box body, and an electromagnetic adsorption lock disposed inside the box body and near the box lid, wherein the box lid is adsorbed and fixed to the box body only for a specified period of time by the electromagnetic adsorption lock.

[0007] Furthermore, an electromagnetic pin is installed inside the box and near the box cover. A pin hole is provided on the inner wall of the box cover near the electromagnetic pin. The electromagnetic pin is inserted into the pin hole only during a specified time period to lock the box cover onto the box body.

[0008] In order to make it easier to open the box lid while ensuring reliable sealing, the sealing ring has a hollow cavity and is composed of a rectangular part and an arc-shaped part.

[0009] A UAV storage and launch container employing the aforementioned lid sealing and locking structure includes an elastic ejection mechanism within the container. The elastic ejection mechanism comprises a rod fixed to the container body, a spring sleeved on the rod body, the lower end of the spring being limited, and the upper end of the spring being connected to a push plate. When the lid is attached to the container body by electromagnetic force, the spring is compressed and stores energy. When the suction force between the lid and the container body is released, the lid is ejected outward by the force released from the spring.

[0010] Preferably, both the designated time period one and the designated time period two are periods before the launch of the UAV, and the designated time period two is earlier than the designated time period one.

[0011] Furthermore, the lid and body of the container are also equipped with locking bolts. Only during the long-term storage of the UAV are the lid and body sealed together by locking bolts. In this state, the electromagnetic adsorption lock is in the unlocked state (not locked), and the latch of the electromagnetic pin is in the retracted state.

[0012] Preferably, multiple sets of the electromagnetic adsorption lock, electromagnetic pin, and elastic ejection mechanism are provided and evenly arranged.

[0013] Preferably, at least two sets of lids are arranged side by side or stacked with the box body.

[0014] Furthermore, during drone transport, the locking bolts are removed, and the lid is secured to the container solely by inserting an electromagnetic pin into its hole. During this period, the lid serves to prevent rainwater from entering. Even after the locking bolts are removed, the lid retains its rainproof properties thanks to the electromagnetic pin.

[0015] Furthermore, a separate desiccant box is provided at the top rear of the box.

[0016] A method for using the aforementioned UAV storage and launch container includes the following steps: Step 1: After loading the drone into the container, close the container lid, then use only the locking bolts to lock the lid and the container, and then store it in the warehouse. Step 2: When the drone leaves the warehouse, first control the locking tongue of the electromagnetic pin to extend, and then lock the box cover to the box body by inserting the locking tongue of the electromagnetic pin into the pin hole. Then remove the locking bolts, and then transport the drone storage and launch box containing the drone to the destination. Step 3: Adjust the UAV storage and launch container to the target tilt angle according to the launch angle of the UAV; Step 4: Control the electromagnetic adsorption lock to lock, and use the electromagnetic adsorption lock to attach the lid to the box body; Step 5: First, control the retraction of the electromagnetic pin's locking tongue to make it exit the pin hole. Then, control the electromagnetic adsorption lock to unlock. At this time, the box cover is instantly pushed out by the elastic ejection mechanism, thus opening the box cover of the UAV storage and launch box.

[0017] Beneficial effects: This invention ensures both reliable sealing of the container opening and damage-free launch of the UAV, while also guaranteeing the reliability and convenience of opening the container lid. It effectively combines the functions of reliable sealing of the container opening and reliable and convenient lid opening. The UAV storage and launch container lid sealing and locking structure provided by this invention is lightweight (only a few kilograms to about twenty kilograms; even for UAVs carrying hundreds of kilograms, the weight of the sealing and locking structure is only about twenty kilograms), simple in structure, occupies little space, is easy to operate, low in cost, and provides excellent safety and sealing during long storage periods. The sealing and locking structure occupies less than one-third the space of conventional mechanical or hydraulic opening mechanisms, and the corresponding manufacturing cost can be reduced by about 50%. In particular, it can reduce the lid opening operation time from about twenty seconds to less than two seconds (steps 4 and 5), making it highly valuable for combat training and practical use.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0020] Combination Figure 4As shown, a box lid sealing and locking structure includes a sealing ring 2 disposed at the mating part of the box lid 4 and the box body 7. An electromagnetic adsorption lock 9 is disposed inside the box body 7 near the box lid 4. The electromagnetic adsorption lock 9 adsorbs and fixes the box lid 4 onto the box body 7 for a specified time period. An electromagnetic pin 8 is also disposed inside the box body 7 near the box lid 4. A pin hole 3 is disposed on the inner wall of the box lid 4 near the electromagnetic pin 8. The electromagnetic pin 8 is inserted into the pin hole 3 for a second specified time period to lock the box lid 4 onto the box body 7. Combined with... Figure 5 As shown, the sealing ring 2 has a hollow cavity 11 and is composed of a rectangular portion and an arc-shaped portion. In this embodiment, the fact that the sealing ring 2 has a hollow cavity 11 and is composed of a rectangular portion and an arc-shaped portion is crucial. Its functions include: ensuring a reliable seal between the lid 4 and the box body 7 while facilitating easier and smoother opening of the lid 4; effectively preventing the sealing ring 2 from adhering to the lid 4 during opening; and facilitating quick installation of the sealing ring 2. Example 2

[0021] Combination Figures 1 to 6 As shown, a UAV storage and launch box includes a lid 4 and a body 7. The lid 4 and body 7 are connected by a sealing and locking structure as described in Embodiment 1. An elastic ejection mechanism 10 is provided inside the body 7. The elastic ejection mechanism includes a rod 12 fixed to the body 7, and a spring 13 is sleeved on the rod 12. The lower end of the spring 13 is limited, and the upper end of the spring 13 is connected to a push plate 14. When the lid 4 is attached to the body 7 by electromagnetic force, the spring 13 is compressed and stores energy. When the attraction between the lid 4 and the body 7 is released, the lid 4 is ejected outward by the force released by the spring 13. The designated time period one and designated time period two are both periods before the UAV launch, and designated time period two is earlier than designated time period one. In this embodiment, a locking bolt 1 is also provided on the lid 4 and body 7. During long-term storage of the UAV, the lid 4 and body 7 are sealed together only by the locking bolt 1. In this state, the electromagnetic attraction lock is unlocked, and the electromagnetic pin's locking tongue is retracted. Multiple sets of electromagnetic adsorption locks 9, electromagnetic pins 8, and elastic ejection mechanisms 10 are installed and evenly distributed. Figure 2 The diagram schematically illustrates six sets of components (electromagnetic adsorption lock 9, electromagnetic pin 8, and elastic ejection mechanism 10); at least two sets of lids 4 are arranged side-by-side or stacked with the box body 7. An independent desiccant box 15 is located at the top rear end of the box body 7. The desiccant box 15 contains desiccant to absorb moisture inside the box, and a lid is provided on the outside of the box body 7. Normally, the box is sealed, allowing for easy replacement of the desiccant without opening the lid. A humidity indicator is also included to monitor the humidity level inside the box. Example 3

[0022] Combination Figures 1 to 6 As shown, a method for using the UAV storage and launch container in Embodiment 2 includes the following steps: Step 1: After loading the drones to be shipped into the box 7, close the box cover 4, and then use only the locking bolt 1 to lock the box cover 4 and the box 7, and then put them into the warehouse for storage. Step 2: When the drone leaves the warehouse, first control the locking tongue of the electromagnetic pin 8 to extend, and lock the box cover 4 onto the box body 7 through the locking tongue pin hole 3 of the electromagnetic pin 8. Then remove the locking bolt 1, and then transport the drone storage and launch box containing the drone to the destination (such as the training ground). Step 3: Adjust the UAV storage and launch container to the target tilt angle according to the launch angle of the UAV; Step 4: Control the electromagnetic adsorption lock 9 to lock (lock), and fix the lid 4 to the box body 7 by the electromagnetic adsorption lock 9; Step 5: First, control the retraction of the locking tongue of the electromagnetic pin 8, causing the locking tongue of the electromagnetic pin 8 to exit the pin hole 3. Then, control the electromagnetic adsorption lock 9 to unlock. At this time, the box cover 4 is instantly pushed out by the elastic ejection mechanism 10, realizing the opening of the box cover 4 of the UAV storage and launch box. At this time, the box cover 4 will proceed according to... Figure 6 The state shown is thrown.

[0023] In this embodiment, both the box body 7 and the box cover 4 are manufactured using a molding process, and the box body 7 and the box cover 4 are provided with grid-like reinforcing ribs. The opening and closing of the electromagnetic adsorption lock 9 and the electromagnetic pin 8 are controlled by a pre-set program. In embodiment 3, the time period from when the drone leaves the warehouse until it reaches its destination and the electromagnetic pin 8 closes can be understood as designated time period two.

[0024] During use, the latch of the electromagnetic pin 8 is extended when the power is off and retracted when the power is on. To prevent the electromagnetic pin 8 from being energized for a long time, it can be manually operated to fix it. Before releasing the locking bolt 1, the latch can also be manually ejected and inserted into the pin hole.

[0025] In use, it can also be operated as follows: Since the locking tongue of the electromagnetic pin 8 is extended when not energized, when the lid is locked by the locking bolt 1 (during long storage), the locking tongue of the electromagnetic pin 8 can be controlled to insert into the pin hole, and the locking bolt 1 acts as the main force for locking. The electromagnetic pin 8 is basically not under force. Only when the locking bolt 1 is loosened does the electromagnetic pin 8 become the main mechanism for restraining the lid. When the electromagnetic adsorption lock 9 is adsorbed, the electromagnetic pin 8 switches to an unforced state again, and it is easy to retract when energized. When there is no constraint from the electromagnetic pin 8, as long as the electromagnetic adsorption lock 9 is unlocked, it will be instantly pushed out by the elastic ejection mechanism 10.

[0026] Taking the UAV storage and launch box in Example 2 as an example, its maximum load capacity is up to 200 kg. Its advantages include: a weight of less than 20 kg (mainly the total weight of the electromagnetic adsorption lock 9, electromagnetic pin 8, and elastic ejection mechanism 10, while a mechanical or hydraulic opening mechanism meeting the same specifications weighs no less than 100 kg); simple structure and small footprint (the distance between the UAV and the inner wall of the box can be controlled within 5 cm, and the length of the box cover sealing and locking structure installation area can be controlled within approximately 15 cm; while a mechanical or hydraulic opening mechanism meeting the same specifications requires approximately 50 cm of reserved space in the installation area); easy operation, low cost, excellent safety and sealing during long storage, and a corresponding reduction in manufacturing cost of approximately 50% (the electromagnetic adsorption lock 9 and electromagnetic pin 8 in the example are small, common control devices, and the elastic ejection mechanism 10 is also composed of several simple components). In particular, it can reduce the box cover opening operation time from approximately 20 seconds to within 2 seconds (steps 4 and 5), possessing high combat training and practical value.

[0027] The UAV storage and launch box and its sealing structure in Example 1 can ensure both reliable sealing of the box opening and non-destructive launch of the UAV, as well as reliability and convenience when opening the box cover. That is, it can take into account both the reliable sealing of the box opening and the reliability and convenience when opening the box cover.
