At present comparatively general unmanned aerial vehicle is four rotor unmanned aerial vehicle, also has the unmanned aerial vehicle of other rotor quantity, like 2 rotors and 6 rotors, no matter which kind of unmanned aerial vehicle generally includes fuselage, horn, foot rest, power component and battery. In order to realize that the unmanned aerial vehicle can stably land on the ground, the foot rests of the unmanned aerial vehicle can protrude out of the unmanned aerial vehicle body, and the number of the foot rests is generally 4, so that the four-foot unmanned aerial vehicle can be centered on the charging platform, and the positive and negative electrodes of the unmanned aerial vehicle battery are attached to the positive and negative electrodes on the centering arm to charge the unmanned aerial vehicle battery.

Besides the above mentioned unmanned aerial vehicle battery charging by means of centralization, the energy supplement to the unmanned aerial vehicle can also be implemented by other means. For example, the mode that unmanned aerial vehicle traded the battery is generally adopted in the existing market, but the cost is very high, trades the battery and need adopt small-size arm and need realize the motion of at least two directions. Taking the battery installation mode of the existing four-rotor aircraft as an example, the long-term battery replacement can cause great abrasion to structural members such as battery buckles and the like, and the maintenance cost is high. Therefore, the unmanned aerial vehicle battery charging mode is still the main mode for energy supplement of the unmanned aerial vehicle.

When unmanned aerial vehicle descends and charges on the platform that charges, its need satisfy charging electrode on the unmanned aerial vehicle and the charging electrode on the platform that charges and stabilize the contact, just can realize charging safety.

Therefore, in order to determine whether the charging anode and the charging cathode of the unmanned aerial vehicle are effectively connected before charging the battery of the unmanned aerial vehicle, an embodiment of the present application provides a charging system for an unmanned aerial vehicle, which includes: the charging device comprises a support, and a first charging electrode, a second charging electrode and at least one first signal electrode which are arranged on the support, wherein the support is used for connecting the charging device with the unmanned aerial vehicle body; the charging platform comprises a third charging electrode, a fourth charging electrode and at least one second signal electrode, wherein the third charging electrode and the fourth charging electrode are used for being respectively connected with the first charging electrode and the second charging electrode when the unmanned aerial vehicle is parked on the charging platform so as to charge the unmanned aerial vehicle, and the at least one second signal electrode is respectively connected with the at least one first signal electrode when the unmanned aerial vehicle is parked on the charging platform so as to determine whether the first charging electrode and the second charging electrode are respectively and effectively connected with the third charging electrode and the fourth charging electrode.

In an embodiment, the support is used for connecting the charging device with a battery on the body of the unmanned aerial vehicle, so that the battery can be charged through the charging device.

When the unmanned aerial vehicle lands, it cannot be determined whether the first charging electrode and the second charging electrode are effectively connected with the third charging electrode and the fourth charging electrode, therefore, at least one first signal electrode may be additionally arranged in the charging device, and the at least one first signal electrode can be connected with the corresponding at least one second signal electrode on the charging platform to form a loop so as to provide a signal to a control system, for example, a control system of the charging system, the charging device or the charging platform, or a third-party control system independent of the charging system, the charging device and the charging platform, and when the signal is detected, it is indicated that the first charging electrode and the second charging electrode are effectively connected with the third charging electrode and the fourth charging electrode.

However, it should be noted that the number of the at least one first signal electrode and the at least one second signal electrode is not limited in the embodiments of the present application, and those skilled in the art may make different selections according to actual needs.

Meanwhile, the embodiment of the present application also does not specifically limit the types of the first signal electrode and the second signal electrode, and those skilled in the art may make different selections according to actual needs. For example, the at least one first signal electrode of the charging device comprises at least one first contact electrode for providing a level signal; and/or at least one first serial port electrode for providing a communication signal. The at least one second signal electrode of the charging platform comprises at least one second contact electrode for providing a level signal; and/or at least one second serial port electrode for providing communication signals.

In one embodiment, the contact electrodes, which may also be referred to as contact signal lines, are formed by metal contact pads. In another embodiment, the serial port electrode is an RX pin or a TX pin of a serial port signal line, which is also composed of a metal contact point.

However, it should be noted that the number and the position of the at least one first contact electrode, the at least one first serial port electrode, the at least one second contact electrode, and the at least one second serial port electrode are not specifically limited in the embodiments of the present application, and those skilled in the art may make different selections according to actual needs.

When the first contact electrode and the second contact electrode are connected, whether the first charging electrode and the second charging electrode of the charging device are effectively connected with the third charging electrode and the fourth charging electrode of the charging platform at a certain moment or not can be preliminarily determined by using the level signal transmitted by the contact electrodes. When the first serial port electrode is connected with the second serial port electrode, whether the first charging electrode and the second charging electrode are effectively connected with the third charging electrode and the fourth charging electrode of the charging platform within a preset time period or not can be further determined by utilizing communication signals sent by the serial port electrode, and therefore whether landing of the unmanned aerial vehicle is stable or not can be determined more accurately.

In one embodiment, the bracket includes: the first extension part is used for bearing a first charging electrode; and the second extension part is used for bearing a second charging electrode, wherein the charging platform is provided with a first accommodating space corresponding to the first extension part and a second accommodating space corresponding to the second extension part.

In order to avoid short circuit between the electrodes, the first charging electrode and the second charging electrode may be disposed on different extension portions, and similarly, the third charging electrode and the fourth charging electrode may be disposed in different receiving spaces.

Specifically, the first accommodating space on the charging platform is used for bearing a third charging electrode, and the second accommodating space is used for bearing a fourth charging electrode. For example, the third charging electrode is provided on an inner wall of the first accommodating space, and the fourth charging electrode device is provided on an inner wall of the second accommodating space.

The first charging electrode is arranged on the outer wall of the first extending portion, the second charging electrode is arranged on the outer wall of the second extending portion, the third charging electrode is arranged on the inner wall of the first accommodating space, and the fourth charging electrode is arranged on the inner wall of the second accommodating space, so that when the accommodating space accommodates the extending portions, the first charging electrode and the second charging electrode are respectively connected with the third charging electrode and the fourth charging electrode.

In one embodiment, at least one first signal electrode is disposed on the first extension portion and/or the second extension portion and spaced apart from the first charging electrode or the second charging electrode.

In order to determine whether the first charging electrode on the first extension portion is effectively connected with the third charging electrode in the first accommodating space on the charging platform more intuitively, the first signal electrode and the first charging electrode may be simultaneously disposed on the first extension portion, and when a signal sent by the first signal electrode is detected, it is indicated that the first extension portion has completely fallen into the first accommodating space of the charging platform, that is, the first charging electrode is effectively connected with the third charging electrode of the charging platform.

Similarly, the first signal electrode and the second charging electrode may be disposed on the second extension portion at the same time. When the first charging electrode and the second charging electrode are effectively connected with the third charging electrode and the fourth charging electrode respectively, the unmanned aerial vehicle is shown to have finished landing.

However, the number of the first signal electrodes on the first extension portion and the second extension portion is not particularly limited in the embodiments of the present application, and one first signal electrode may be carried on the first extension portion and the second extension portion, or more than one first signal electrode may be carried on the first extension portion and the second extension portion.

In order to avoid short-circuiting between the electrodes, at least one first signal electrode may be provided spaced apart from the first charging electrode or the second charging electrode.

At least one first signal electrode is disposed on an outer wall of the first extension portion and/or the second extension portion, and at least one second signal electrode is disposed on an inner wall of the first receiving space and/or the second receiving space, so that the at least one first signal electrode is connected with the at least one second signal electrode when the receiving space receives the extension portion.

In one embodiment, the bracket further includes: and the at least one third extension part is used for carrying at least one first signal electrode.

At least one first signal electrode is disposed on an outer wall of the at least one third extension portion, and at least one second signal electrode is disposed on an inner wall of the at least one third receiving space, so that the at least one first signal electrode is connected with the at least one second signal electrode when the receiving space receives the extension portion.

In order to avoid the situation that the first signal electrode and the first charging electrode or the second charging electrode are distributed on one extension part to cause short circuit between the electrodes, the first signal electrode can be separately arranged on the third extension part.

However, the number of the first signal electrodes on each of the at least one third extension portion is not specifically limited in the embodiments of the present application, and one first signal electrode may be disposed on one third extension portion, or more than one first signal electrode may be disposed on one third extension portion, and meanwhile, the embodiments of the present application are not specifically limited in the numbers of the third extension portions.

For example, the at least one third extension comprises: two third extensions, two third extensions are arranged with first extension and second extension in array, and two third extensions are arranged diagonally, and first extension and second extension are arranged diagonally.

In order to prevent the first charging electrode and the second charging electrode from being in poor contact with the third charging electrode and the fourth charging electrode of the charging platform due to the fact that the unmanned aerial vehicle is not landed smoothly or due to dirt or installation errors on the first extending portion and the second extending portion, the two third extending portions can be arranged diagonally, and the first extending portion and the second extending portion are arranged diagonally.

Fig. 1a is a schematic diagram showing a positional relationship among the first extension portion, the second extension portion, and the two third extension portions, which shows that the two third extension portions are arranged in an array with the first extension portion and the second extension portion.

As shown in fig. 1a, the first extension is located at the position of circle a, the second extension is located at the position of circle B, and the two third extensions are located at the positions of circles C and D. In other words, the four extensions are arranged in a 2 x 2 array, wherein the first extension and the second extension are arranged diagonally and the two third extensions are arranged diagonally. At this time, when signals emitted by the signal electrodes on the two third extending portions where the C and D positions are located are detected, it is indicated that the two third extending portions where the C and D positions are located have completely fallen into the accommodating space of the charging platform. Since both the diagonal third extensions have completely fallen into the receiving space of the charging platform, which means that the diagonal first and second extensions have completely fallen into the receiving space of the charging platform, the first and second charging electrodes have been effectively connected to the third and fourth charging electrodes of the charging platform.

However, when the at least one third extension includes four third extensions, as shown in fig. 1B, the first extension is located at the position of circle a, the second extension is located at the position of circle B, and the four third extensions are located at the positions of circles C, D, E and F. In other words, six extensions are arranged at six vertices of a regular hexagon. Similarly, since the four diagonal third extending portions all have completely fallen into the accommodating space of the charging platform, which means that the diagonal first extending portions and diagonal second extending portions have completely fallen into the accommodating space of the charging platform, the first charging electrode and the second charging electrode are effectively connected to the third charging electrode and the fourth charging electrode of the charging platform.

It should be noted that the arrangement of the first extension portion, the second extension portion, and the third extension portion shown in fig. 1a and 1b is only an example, and the embodiment of the present application does not limit the specific arrangement of the first extension portion, the second extension portion, and the third extension portion, which may be different according to the number of the third extension portions.

In one embodiment, when the at least one third extension comprises: two third extensions, the at least one first signal electrode comprising: when four first signal electrodes are arranged, two first signal electrodes are carried on one of the two third extending portions, and two first signal electrodes are carried on the other one of the two third extending portions. The arrangement direction of the two first signal electrodes of one of the two third extension portions and the arrangement direction of the two first signal electrodes of the other of the two third extension portions are perpendicular to each other.

As shown in fig. 1c, the left and right circular rings are located at two third extending portions, two black less than quarter circular rings in the left circular ring are two first signal electrodes facing in the horizontal direction, two black less than quarter circular rings in the right circular ring are two first signal electrodes facing in the vertical direction, and therefore the arrangement direction of the two first signal electrodes of one of the two third extending portions is perpendicular to the arrangement direction of the two first signal electrodes of the other of the two third extending portions.

Through setting up direction mutually perpendicular's two pairs of first signal electrodes, can detect the third extension and whether all fall into charging platform's third accommodation space along all directions to whether can confirm first charging electrode and second charging electrode and third charging electrode and fourth charging electrode and laminate fully more accurately.

In order to avoid that the first and second charging electrodes and the third and fourth charging electrodes are not sufficiently attached due to the extension portions being deformed in the same direction, as shown in fig. 1d, two third extension portions are diagonally arranged (on the lower left and upper right, respectively), the first and second extension portions are diagonally arranged (on the upper left and lower right, respectively), and the arrangement direction (horizontal direction) of the two first signal electrodes of one of the two third extension portions and the arrangement direction (vertical direction) of the two first signal electrodes of the other of the two third extension portions are perpendicular to each other.

The above-described embodiments have been described in which the first charging electrode and the second charging electrode are located in different extensions, and the following embodiments will focus on the description that the first charging electrode and the second charging electrode are located in the same extension.

In another embodiment of the present application, the bracket further comprises a fourth extension for carrying the first charging electrode and the second charging electrode.

In order to avoid short circuit between the first charging electrode and the second charging electrode, the first charging electrode and the second charging electrode are arranged at intervals.

In one embodiment, at least one first signal electrode is disposed on an outer wall of the fourth extension portion and spaced apart from the first and second charging electrodes. At least one second signal electrode is disposed on an inner wall of the fourth receiving space corresponding to the fourth extension portion,

in order to avoid short circuit among the at least one first signal electrode, the first charging electrode and the second charging electrode, the at least one first signal electrode is arranged at a distance from the first charging electrode and the second charging electrode.

The first signal electrode, the first charging electrode and the second charging electrode are arranged on the extension portion, so that whether the first charging electrode and the second charging electrode are effectively connected with the third charging electrode and the fourth charging electrode or not can be determined more visually, and the structure of the charging device can be simplified.

In another embodiment of the present application, all of the above-mentioned extensions may be shaped as a cone, a cylinder or a funnel, and all of the above-mentioned receiving spaces for receiving the extensions may be shaped as a cone, a cylinder or a funnel. The shape of the extension matches the shape of the corresponding receiving space, for example, when the extension is tapered, the receiving space is also tapered.

Shown as a cone in fig. 2a and a cylinder in fig. 2b and a funnel in fig. 2 c.

In an embodiment, when the first and second extensions are in the shape of a cone, a cylinder, or a funnel, the first and second charging electrodes may be carried on outer sidewalls of the cone, the cylinder, or the funnel. The circular rings on the outer side wall of the cone, cylinder or funnel are the metal contacts constituting the first and second charging electrodes, and the black circular rings shown in fig. 3a correspond to the metal contacts constituting the first and second charging electrodes.

In an embodiment, when the first extension portion and the second extension portion are shaped as a cylinder or a funnel, the first charging electrode and the second charging electrode may be carried on the outer side of the bottom surface of the cylinder or the funnel, and the ring on the outer side of the bottom surface of the cylinder or the funnel is a metal contact point constituting the first charging electrode and the second charging electrode, and the black ring shown in fig. 3a corresponds to the metal contact point constituting the first charging electrode and the second charging electrode.

In an embodiment, when the first and second extending portions are shaped as funnels, the first and second charging electrodes may be carried on outer sidewalls of the steps of the funnels, and the fold lines of the outer sidewalls of the steps of the funnels are metal contact points constituting the first and second charging electrodes, and the black fold lines as shown in fig. 3b correspond to the metal contact points constituting the first and second charging electrodes.

Of course, when the first charging electrode and the second charging electrode are disposed on the same extension portion, one of the first charging electrode and the second charging electrode may be carried on the outer side of the bottom surface of the cylinder or the funnel, and the other of the first charging electrode and the second charging electrode may be carried on the side wall of the cylinder or the funnel, and the embodiment of the present application does not specifically limit the positional relationship between the first charging electrode and the second charging electrode.

In an embodiment, when the first signal electrode and the first charging electrode or the second charging electrode are disposed on the same extension, the first charging electrode or the second charging electrode may be carried on an outer sidewall of the cone, the cylinder, or the funnel, and then the first signal electrode and the first charging electrode or the second charging electrode may be disposed on the outer sidewall of the cone, the cylinder, or the funnel at a certain distance.

In an embodiment, when the first signal electrode and the first and second charging electrodes are disposed on the same extension, the first and second charging electrodes may be carried on the outer side of the bottom surface of the cylinder or the funnel, and then the first signal electrode may be disposed on the outer side wall of the cylinder or the funnel, or disposed on the outer side of the bottom surface of the cylinder or the funnel at a distance from the first and second charging electrodes.

In one embodiment, the third charging electrode, the fourth charging electrode and the at least one second signal electrode of the charging platform are disposed inside the accommodating space to be connected/contacted with the first charging electrode, the second charging electrode and the at least one first signal electrode. The plurality of receiving spaces are distributed in the same manner as the plurality of extensions, as shown in fig. 1a and 1 b.

Taking the structure of the receiving space and the extension portion as funnel-shaped as an example, fig. 3c shows a schematic cross-sectional view of the receiving space and the extension portion provided by an embodiment of the present application. As shown in fig. 3c, the grid-dog-leg-shaped electrode of the accommodating space 31 is connected/contacted with the black dog-leg-shaped electrode of the extension 32.

However, the size of the metal contact points constituting the above electrodes is not limited in the embodiments of the present application, and for example, the metal contact points may be black circular rings as shown in fig. 3a, black semicircular rings as shown in fig. 4a, black quarter circular rings as shown in fig. 4b, or black smaller than quarter circular rings as shown in fig. 4 c. That is, the metal contact points constituting the electrode may be disposed around the ring extension or the accommodating space, or disposed around the ring extension or the accommodating space by half, a quarter, or less than a quarter.

In order to ensure that the effective contact area of the charging electrode is larger so as to realize rapid charging, the metal contact points forming the first charging electrode, the second charging electrode, the third charging electrode and the fourth charging electrode are in a circle layout of the ring extension part and the accommodating space.

In one embodiment, the serial port electrodes may be disposed on the same extension or accommodation space as the contact electrodes, i.e., one contact electrode corresponds to one serial port electrode. After detecting the level signal that contact electrode sent, reuse serial ports electrode to communicate to can confirm whether the extension at serial ports electrode and contact electrode place has fallen into charging platform's accommodation space completely.

That is to say, an extension of support can correspond an unmanned aerial vehicle's foot rest, consequently, when the support includes four extensions, unmanned aerial vehicle's four foot rests just constituted this charging device's support, and the unmanned aerial vehicle's four foot rests that set up charging electrode and first signal electrode constitute this charging device. It will be appreciated that the number of extensions may also be less than the number of feet, i.e. not all feet of the drone constitute a cradle for the charging device, e.g. two of the four feet are provided with an extension, i.e. they constitute the cradle.
