[0033] In order to provide a further understanding of the purpose, structure, features and functions of the present invention, the following detailed description is given in conjunction with the embodiments.

[0034] Figure 1A is a schematic diagram of an unmanned vehicle according to an embodiment of the present invention. Figure 1B for Figure 1A Schematic diagram of one of the battery packs being removed from the body. Figure 1C for Figure 1A A magnified schematic diagram of the two battery packs.

[0035] Please refer to Figure 1A In this embodiment, the unmanned vehicle 100 includes a body 110 and a plurality of battery packs (three battery packs 120, 130, 140 are schematically shown). The battery packs 120, 130, 140 are detachably stacked on the body 110, wherein the body 110 uses the power of the battery packs 120, 130, 140 in sequence along the anti-gravity direction L. Here, the unmanned vehicle 100 is, for example, a drone.

[0036] In detail, each battery pack 120, 130, 140 has an assembly surface A, wherein the battery pack 140 is stacked on the battery pack 130 in a manner parallel to the assembly surface A (i.e., horizontally and transversely), and the battery pack 130 is stacked on the battery pack 120 in a manner parallel to the assembly surface A. In one embodiment, the battery pack 120 is assembled on the body 110, and the battery packs 130 and 140 are detachably stacked on the battery pack 120, wherein the battery pack 120 may be, for example, a built-in battery pack, and the battery packs 130 and 140 may be, for example, disposable battery packs. In another embodiment, the battery packs 120, 130, 140 are all disposable battery packs. It should be noted that here, three horizontally and transversely stacked battery packs 120, 130, 140 are used as an example for illustration, but are not limited thereto. In other embodiments, the number of battery packs may be added or removed according to actual usage requirements.

[0037] Since the battery packs 120, 130, 140 are installed in a horizontal stack, multiple battery packs 120, 130, 140 can be installed when the unmanned vehicle 100 takes off to expand the battery capacity, which can have the advantages of large battery capacity and long endurance. In one embodiment, the specifications of the battery packs 120, 130, 140 can be the same, wherein the specifications include battery capacity, appearance size and structural design, but are not limited thereto.

[0038] Next, please also refer to Figure 1A as well as Figure 1BIn this embodiment, the body 110 of the unmanned vehicle 100 uses the power of the battery packs 120, 130, and 140 in sequence along the anti-gravity direction L, that is, the body 110 uses the power of the battery packs 140, 130, and 120 in sequence. Therefore, the power of the battery pack 140 at the bottom will be exhausted first, and the exhausted battery pack 140 can be removed at an appropriate location or height to reduce the weight and form the unmanned vehicle 100A. At this time, the weight of the unmanned vehicle 100A is reduced, the flight performance is improved, and the flexibility is high, that is, it has the advantages of light weight and high flight speed of small batteries.

[0039] Since the battery packs 120 , 130 , 140 are installed in a horizontally stacked manner, when the battery packs 120 , 130 , 140 are added or removed, the unmanned vehicle 100 , 100A will not have a problem of losing balance due to a shift in the center of gravity.

[0040] Next, please also refer to Figure 1A , Figure 1B as well as Figure 1C In this embodiment, the battery packs 120, 130, and 140 are stacked on the body 110 in a manner of magnetizing attraction, and the battery pack 140 among the battery packs 120, 130, and 140 is removed from the body 110 in a manner of demagnetizing. Here, magnetizing refers to the generation of a magnetic field by exciting an electric current through a coil. More specifically, each battery pack 130 (or battery pack 140, battery pack 120) has a first surface S1 and a second surface S2 opposite to each other, and each battery pack 130 (or battery pack 140, battery pack 120) includes an electromagnet group E and a magnetic structure group M. The electromagnet group E is disposed on the first surface S1, and the magnetic structure group M is disposed on the second surface S2. The electromagnet group E includes an electromagnet N pole E11 and an electromagnet S pole E12, and the magnetic structure group M includes a magnetic structure N pole M11 and a magnetic structure S pole M12. The electromagnet N pole E11 and the magnetic structure S pole M12 are disposed opposite to each other, and the electromagnet S pole E12 and the magnetic structure N pole M11 are disposed opposite to each other. In one embodiment, the magnetic structure group M is, for example, a plurality of magnets or a plurality of iron sheets, but is not limited thereto.

[0041] Furthermore, each battery pack 130 (or battery pack 140, battery pack 120) also includes a battery management module P, which is electrically connected to the electromagnet group E to activate or deactivate the magnetism of the electromagnet group E. Here, each battery management module P can control the energy output of the battery pack 120 (or battery pack 130, battery pack 140), the switch of the electromagnet group E, the power detection of the battery pack 120 (or battery pack 130, battery pack 140), and the data transmission of the flight control computer of the unmanned vehicle 100 (or unmanned vehicle 100A), wherein the flight control computer can decide whether to add or remove the battery pack and which battery pack to supply power. In other words, by controlling the switch of the electromagnet group E inside each battery pack 120 (or battery pack 130, battery pack 140), the function of removing or adding the battery pack can be achieved. In addition, each battery pack 130 (or battery pack 140, battery pack 120) has a plurality of contacts C1, C2, wherein the contact C1 is located on the first surface, and the contact C2 is located on the second surface S2. When stacked, the contact C1 of the battery pack 130 can be electrically connected to the contact C2 of the battery pack 140 to achieve electrical and communication connection.

[0042] For example, the battery management module P of the battery pack 130 activates the magnetism of the electromagnet group E to magnetize and attract the magnetic structure group M of the battery pack 140 and stack them on the body 110. At this time, the N pole E11 of the electromagnet of the battery pack 130 and the S pole M12 of the magnetic structure of the battery pack 140 are magnetized and attracted, and the S pole E12 of the electromagnet of the battery pack 130 and the N pole M11 of the magnetic structure of the battery pack 140 are magnetized and attracted, so that the battery pack 140 is stacked on the battery pack 130. On the other hand, the battery management module P of the battery pack 130 turns off the magnetism of the electromagnet group E to demagnetize the magnetic structure group M of the battery pack 140 and remove it from the body 110. In short, the stacked battery packs 120, 130, and 140 can be positioned by magnetism by activating or turning off the magnetism of the electromagnet group E through the battery management module P, without relying on a locator.

[0043] Figure 2A and Figure 2B They are Figure 1A Schematic diagram of the unmanned vehicle charging. Please also refer to Figure 2A as well as Figure 2BWhen the unmanned vehicle 100 is in a state of charging, the battery pack 140 stacked on the body 110 and farthest from the body 110 causes at least one supplementary battery pack 150 on the ground charging station G to be stacked thereon to replenish the power through the method of magnetic attraction, thereby forming an unmanned vehicle 100B having the battery packs 120, 130, 140 and the supplementary battery pack 150. Here, the ground charging station G can place the fully charged supplementary battery pack 150 at a designated location. The unmanned vehicle 100 will first fly downward, so that the battery pack 140 and the supplementary battery pack 150 on the ground charging station G are magnetically attracted to form the unmanned vehicle 100B, and then fly upward away from the ground charging station G. In one embodiment, the unmanned vehicle 100 can add one or more supplementary battery packs 150 through one landing, or add one supplementary battery pack 150 through one landing, and add multiple supplementary battery packs 150 through multiple landings. It can be selected according to needs and is not limited here. In short, the purpose of long-distance flight can be achieved by setting up multiple ground charging stations G along the flight route.

[0044] Furthermore, when the power of the supplementary battery pack 150 is greater than the power of the battery pack 140, the supplementary battery pack 150 can charge the battery pack 140 (or, with the battery pack 130 and the battery pack 120), which is an upward recharge mechanism. To be more specific, when the battery pack 140 is loaded and replenished, the body 110 will not only give priority to using the power of the supplementary battery pack 150, but the supplementary battery pack 150 will also recharge the upper battery pack 140 (or, with the battery pack 130 and the battery pack 120) that is not fully charged through the upward recharge mechanism, so that the power of the battery packs 120, 130, 140 and the supplementary battery pack 150 always meets the condition that the battery pack 120≧battery pack 130≧battery pack 140≧supplementary battery pack 150. The upward recharge mechanism can ensure that the battery pack at the bottom is exhausted more quickly and the battery pack at the bottom is discarded as soon as possible, so as to achieve the effect of weight reduction. In addition, the upward recharging mechanism will prevent the upper battery pack (such as battery pack 140) from exhausting its capacity to maintain the electromagnet suction, thereby preventing the entire string of stacked battery packs (such as battery packs 120, 130, 140) from falling off.

[0045] Figure 3A and Figure 3B for Figure 1B Schematic diagram of the unmanned vehicle charging. Please also refer to Figure 1B , Figure 3A as well as Figure 3BWhen the unmanned vehicle 100A is in a state of being charged, the battery pack 140 stacked on the body 110 and farthest from the body 110 can be removed first to expose the battery pack 130. The battery pack 130 allows at least one supplementary battery pack 150 on the ground charging station G to be stacked thereon to replenish the power through magnetic attraction, thereby forming an unmanned vehicle 100C having the battery packs 120, 130 and the supplementary battery pack 150. In other words, the unmanned vehicle 100A first removes the battery pack 140 with low power or exhausted power at the bottom, and then lands on the ground charging station G, so that the battery pack 130 and the supplementary battery pack 150 on the ground charging station G are magnetically attracted to each other to form the unmanned vehicle 100C, and then flies upward away from the ground charging station G, so as to achieve the effect of unloading as soon as possible and reducing weight. In one embodiment, the unmanned vehicle 100A can add one or more supplementary battery packs 150 through one landing, or add one supplementary battery pack 150 through one landing and multiple landings to add multiple supplementary battery packs 150. The choice can be made according to needs and is not limited here.

[0046] Furthermore, when the power of the supplementary battery pack 150 is greater than the power of the battery pack 130, the supplementary battery pack 150 can charge the battery pack 130 (or, with the battery pack 120). Specifically, when the battery pack 130 is loaded and supplemented, the machine body 110 will not only give priority to using the power of the supplementary battery pack 150, but the supplementary battery pack 150 will also recharge the under-charged battery pack 130 (or, with the battery pack 120) through the upward recharge mechanism, so that the power of the battery packs 120, 130 and the supplementary battery pack 150 always meets the condition that the battery pack 120≧battery pack 130≧supplementary battery pack 150.

[0047] Figure 4A and Figure 4B for Figure 1A Another diagram of an unmanned vehicle charging. Please also refer to Figure 4A as well as Figure 4BWhen the unmanned vehicle 100 is in a state of charging, the battery pack 140 stacked on the body 110 and farthest from the body 110 causes at least one supplementary battery pack 150 on the air charging station T to be stacked thereon to replenish the power through the method of magnetic attraction, thereby forming an unmanned vehicle 100B having the battery packs 120, 130, 140 and the supplementary battery pack 150. Here, the air charging station T can place the fully charged supplementary battery pack 150 at a designated position above the drone. The unmanned vehicle 100 will first approach the air charging station T downward, so that the battery pack 140 and the supplementary battery pack 150 on the air charging station T are magnetically attracted to form the unmanned vehicle 100B, and then fly upward away from the air charging station T. In one embodiment, the unmanned vehicle 100 can attach one or more supplementary battery packs 150 by approaching once, or attach one supplementary battery pack 150 by approaching once, and attach multiple supplementary battery packs 150 by approaching multiple times, which can be selected according to needs and is not limited here. In short, the purpose of long-distance flight can be achieved by setting up multiple aerial charging stations T along the flight route.

[0048] When the power of the supplementary battery pack 150 is greater than the power of the battery pack 140, the supplementary battery pack 150 can charge the battery pack 1400 (or, with the battery pack 130 and the battery pack 120). In other words, when the battery pack 140 is loaded and supplemented, the body 110 will not only give priority to using the power of the supplementary battery pack 150, but the supplementary battery pack 150 will also recharge the undercharged battery pack 140 (or, with the battery pack 130 and the battery pack 120) through the upward recharge mechanism, so that the power of the battery packs 120, 130, 140 and the supplementary battery pack 150 always meets the condition that the battery pack 120≧battery pack 130≧battery pack 140≧supplementary battery pack 150.

[0049] Figure 5A and Figure 5B for Figure 1B Another diagram of an unmanned vehicle charging. Please also refer to Figure 1B , Figure 5A as well as Figure 5BWhen the unmanned vehicle 100A is in a state of charging, the battery pack 140 stacked on the body 110 and farthest from the body 110 is removed to expose the battery pack 130. The battery pack 130 allows at least one supplementary battery pack 150 on the aerial charging station T to be stacked thereon to replenish the power through magnetic attraction, thereby forming an unmanned vehicle 100C having the battery packs 120, 130 and the supplementary battery pack 150. In other words, the unmanned vehicle 100A can first remove the battery pack 140 with low power or exhausted power at the bottom, and then approach the aerial charging station T, so that the battery pack 130 and the supplementary battery pack 150 on the aerial charging station T are magnetically attracted to form the unmanned vehicle 100C, and then fly upward away from the aerial charging station T, so as to achieve the effect of unloading as soon as possible and reducing weight. In one embodiment, the unmanned vehicle 100A can approach and add one or more supplementary battery packs 150 at a time, or approach and add one supplementary battery pack 150 at a time and approach and add multiple supplementary battery packs 150 multiple times. The choice can be made according to the needs and is not limited here.

[0050] When the power of the supplementary battery pack 150 is greater than the power of the battery pack 130, the supplementary battery pack 150 can charge the battery pack 130 (or, with the battery pack 120). In other words, when the battery pack 130 is loaded and supplemented, the body 110 will not only give priority to using the power of the supplementary battery pack 150, but the supplementary battery pack 150 will also recharge the under-charged battery pack 130 (or, with the battery pack 120) upward through the upward recharge mechanism, so that the power of the battery packs 120, 130 and the supplementary battery pack 150 always meets the battery pack 120≧battery pack 130≧supplementary battery pack 150.

[0051] Figure 6 for Figure 1A Schematic diagram of an unmanned vehicle encountering an emergency. Please refer to Figure 6 In this embodiment, when the unmanned vehicle 100 is in an emergency state, the battery packs 130 and 140 can be removed from the body 110 by demagnetization. That is to say, if an emergency situation occurs during flight, such as jamming a gun or capturing a gun, the unmanned vehicle 100 needs to escape urgently by removing some of the battery packs 130 and 140 to reduce weight, increase altitude at the fastest speed, or escape from the scene at the highest speed. On the other hand, the battery packs 130 and 140 that are removed and fall can confuse the enemy to achieve the effect of cutting off the tail and surviving.

[0052] In summary, in the design of the unmanned vehicle of the present invention, the unmanned vehicle includes a body and a plurality of battery packs, and the plurality of battery packs are detachably stacked and arranged in the gravity direction of the body, wherein the body uses the power of the plurality of battery packs in sequence along the anti-gravity direction. Therefore, when the unmanned vehicle takes off, a plurality of battery packs can be installed, and the advantages of large battery capacity and long endurance can be obtained; and, because the battery pack at the bottom can be used preferentially, the battery pack that has run out of power can be removed, and the advantages of small battery light weight and fast flight speed can be obtained. In this way, the unmanned vehicle of the present invention can have the advantages of both large batteries and small batteries.
